Okay, I think we can start going live. Hello everyone, I am Sanjay Gupta. I welcome you on Sanjay Gupta Tech School. So today we are having day 13 of this Appian Bootcamp and I have Ankit with me. Welcome Ankit on the channel. So Ankit will be delivering one more session on Appian and I hope those who are following the sessions, so you are finding these sessions interesting and if you need an instance or environment, so just share your request in the telegram group so that Ankit can help you to have the environment and you can do some practice. And if you want to receive timely notification, you can follow Sanjay Gupta Tech School YouTube channel, LinkedIn, Instagram and Telegram and session tracker link is available in the video's description. Okay, so with this I hand over Mike to Ankit. So Ankit will let you know a few more things and then you'll start with the session. Thank you. Thanks Sanjay sir. So if you want to watch any recorded sessions that we know, that is already we have done in like one to twelve sessions. So you can check it on the CodeMestro YouTube channel and there are other types of videos or other AP related videos so you can go through that also. And if you have any questions, any query, you can post on the CodeMestro's telegram channel and we will deliver back on that. So in our last sessions, we discussed about interfaces and expressions. Today we will discuss about process model. So process model is a very important and very powerful AP in feature. So first, what is process model? So generally, you know that as we discussed in our first session also like you know, every business has a process, right? So suppose I'm applying for a loan, so I have to fill the information, the loan information, then it will store into the database and it will go to the, you know, the approvers for approval. So the approver will do some checks like if every, you know, information is correct or not, if there is some issue in that information, then he can, he also can reject the request. So that is something like a process. So in APN, we represent this type of processes or this type of steps in a graphical manner, okay? That is process model. But process model is not only the represent graphical representation of a process of a business process, but it is in a executable form. So not only we can represent, but we can execute the process with the real time data, okay? And we can run the end to end workflow. So how it creates, I can show you. So similar to interface, other type of components, we will go to new and we'll take on process model, okay? And in this one, we can have, you know, a space between the words, okay? There's no need of underscore, like AP, get emperor details. Suppose I want user to input the information in a form. So we are saving to this folder. So like, you know, that interface, expressions rules, we save into rule type of folder, right? And documents, we save into document type of folder. So to save the process model, we create process model type of folder. Now, it has the security like AP user one, that is, that have the viewer security, AB administrator one, one have the administrator security that we can change, okay? We can have editor level of security, manager level of security, viewer level of security, initiator or deny. Now I will save this process. It will open in a process modeler. Okay, so this is process model, modeler where we create the process model. So in this one, you can see we have a start node and end node, okay? Like from here process will start and on this node process will be completed. So between two, these two nodes, we will configure our steps that we need to complete, okay? And we will connect, connect all of those nodes, all of those steps in the help of these lines. So now I'm removing this one, okay? First, you can see here we have file tab, okay? I can go to file tab, and I can configure the security again. If I want to update the security, I can update the security and there are other, you know, steps that we can use or other options that we can use, like save, save as, save as publish, version, start process for debug, print, preview, print, property and exit, okay? So we will, so like if I want to create new process model from here, I can use this one. If I want to open the process model, okay? In a particular, from a particular folder, I can use this. If I want to close, I can use this one in suppose in this particular process model or if there are multiple process models open, then I can use this closed or to close all of the process models. If I want to save the process model just to save but not to publish like the information will be saved, but those information won't be in executable form, okay? So we can use save if I want to create a different process model with, you know, clone like the same, then we can use save as if I want to publish, that means in that case, the information will be in executable form and it will create the new version. So in every case, know that whenever we do the save and publish, APN create a new version every time, like same as interface, in interface expression rule if I'm clicking on save every time, APN create the new version. So I can go to the older version and can check the code and can compare the code and I can revert also the code with the help of that. With the in the security, I can check the security and I can update the security. So it have different different levels of, you know, rights like process administrator have editor my manager viewer initiator and deny. Okay, so initiator is the lowest security level that have minimum security like an initiate the process viewer can initiate and can see the process manager have more security like and reassign the process editor can have more security than manager and then process administrator that I will share with you over the telegram group so that you can go through that. Okay, so like that this weekend, we have we can secure, you know, give the security to the process model. And now there are some properties right here, this is a property there. And you can see here, we have multiple types, like general type variables that process start form deadline alerts and data management. Okay, so first is general type. So in general time, you can see here this is process model ID. Okay, so process model ID is the unique ID in a particular environment. So suppose I am creating the I have created this process model on this environment, so it will be unique and there won't be any other process model with the same ID. Okay, every process model will have different ID. Okay, those that is process model ID. But if I deploy this particular process model on different environment, at the time process model ID will be changed. Okay. That means process model ID is unique, you know, in a same environment. But if we change the environment, process model ID will be different. Process model, you ID is the universal ID that will be same in, okay, in multiple environments. So if I'm deploying deploy this particular process model in other environment, that time also process model, you ID will be same process model ID might model ID will be changed, but process model, you ID won't change. Okay, process model link that is the name that we give to the process model okay, that where we create description is the same that we have given, but we can update from him. Then one process model display name, okay, so process display name. So you know that as you discuss process model is a blueprint, okay, or a template that define like what all manipulations on data, what all calculations on data will be there, what all nodes will be there, what all configurations will be there, but it is not a executed form. Okay, when we run the process with the particular data, then it create process instances, okay. So it, you can think like, like, suppose there is a class or there is, there is an employee, okay. So I'm asking to, you know, input the employee details and then performing some calculations on the data, storing into the database and then assigning some tasks to different different department, okay, so that is a process model that we configured. But that employee can be an employee can be anyone else, so everyone come and fill the information. So for each and every employee one instance run for a particular process model that we call process instance, okay. So this process display name in a dynamic name. That means suppose this particular process model is running for an case, so it will be different if it is running for other user like john. So in that case, it will be different. Okay, so process model display name is different, that we can define from here. Okay, we can concatenate some information here and we can create is a dynamic. Okay, like from here, we can define the process priority. It can be low, normal high. If, if suppose we are calling this process model from email that we will discuss later, but yeah, we can call process model from email. So we can get the attachments in a particular folder. Okay, so whatever I'm sending that attachment will be saved into particular folder that folder we can define here. If I want to take it from a public events, then I can click on this checkbox and this one define the time zone like if this process is running in ISP time zone or other time zone. Okay, but if I click on this checkbox, then it will override with the initiators time zone. Okay, so suppose if it is ISP, but the initiator of the process model is from other time zone, then it will override. So this is general type where we define some configuration. Now, same like interface is expression rule like an interface we create rule input right that is a variable global variable for a particular rule. Same like we create the variables in process model also, but here we call it as process variables. Okay, in interface expression rule we call it rule input. So same like interface we create the variable like by clicking here. Okay, and we can define the type like suppose I'm creating a name, it is text type parameter. If I configure it with parameter that means it will come from somewhere else. Okay, if I make it as required, that means process want to start until the value we have some values here. If it is array type or multiple type, then we click on this checkbox hidden like if I do not want to show the particular variable in the history. Okay, then I use the hidden I will show you how we can see the process history. Like this we create the variable we can create multiple num, okay, number of variables I want to create other variable I could click like this. So like this we create the variable.  So if I want to configure that interface here, I have to use this process start form. Okay, so by I can browse from here and I can use you know, configure I can add that interface here. Okay. So from interface we can pass the variables into process model also that we will discuss. Now other tab is deadline. Okay, that we can use to define the deadline of the process model. Okay, that will display. So in this one, you can define the deadline as minutes and hours as the weeks or months. Okay, or you can define the particular date and time as well if you select this one. Okay, so like this, we define the deadline of the process model. This is alerts. Okay, so suppose any of the process know even I'm running some processes for the particular process model, and it break the somewhere build somewhere due to some reason, it might be security or anything else. Okay, so APN send an alerts in the design attempt. Okay, so that will go accordingly, you know, to this group or here we can define the group or if there is any constant of the group we can define. So it will go to the group users. Okay, that is defined here. Okay, so if I suppose if I define a user here, a group here, so it will come to the users of that group. It is not a best practice to define the user here. Okay, we should define groups only. Now, data management policies. Okay, so you can see here we have four options. Okay, one is like default, that is auto archive process seven days after completion or cancellation of the process. Second is archive process, and that we can define here seven eight nine and then delete and then do not automatically clean up processes. So that means support one process model is completed. Okay, a process instance is completed. So like sir, the process instance for employee information, and I submitted my information, and it is already written to the database, and everything is done for and process more process instance is completed. Now, the process, this management policies define like how many days after completion, it will be memory. Okay, so archival is like we are not permanently delete the process instance. Okay, but we are moving from its active memory to other memory. But and it can be refactor like you know that we can again, active that process instance, okay, with the help of some smart services. But if I'm using this delete process property, in that case, it will be completely deleted. Okay, from that API, and we cannot recover that. So that is delete. So if there's anything that we need to check after process completion, we generally we use, there is any like, you know that there is any user activity in that interface. So we use archival if there is any user activity, and process is simply not as much as useful to check the history, we use the deletion policy. So these are some properties. Okay, like general type, we have discussed variables, we can create from here. If there is any interface that we need to configure, we can configure from here. If we have defined the deadline of the process model, we can define and alerts, we can define from here alerts. And you don't know, these are important parameters, we have, we should configure that if I do not define the alerts. In that case, it will, you know, send the error message to everyone. And if I do not define this archival policy, like 15 or 20 days or something like that. So the process instance will be in memory till the date. And if there are a lot of process instances, then it will consume the memory. Okay, so like this, we define the properties. Now in left side, you can see here, we have some components, right? Like script task, call integration, user input task, encrypt PDF, script as a process and event, receive message, rules and message, or there are some gateways also and complex, like jure, right? And there are more, there are more like delete records, delete from data identity. So these all are components or nodes that we can use into the process model. Okay, so suppose I'm using script task, okay, if I want to use this node, between these two, you know, that start node and end node, I have to go to here and I connect with this line. So when I debug this process model, so when I will say when publish this, okay, and if I debug by clicking here. So now it is the instance of that process model. Okay, this is process model. And this is the instance of this particular process model. If I again debug, it will create new instance. So process model is same, but it is creating multiple instance, like you can see here, this is first instance, this is second instance. Okay, if I want to edit something in instance, I can open in edit process view, and I can change something. Okay. In that case, if I edit one particular process instance, it will pose the process instance. Okay, so once I change and, you know, save the changes at the time, I have to close this one so that it will again reach out. Okay, so this, this is process instance, and this is process model. Okay. So like this, we configure the nodes. So this is one type of node or component that we call a script task. Okay, other component is user input task. Okay, so these are script tasks and user input tasks. So some of the events or tasks can be done by APN itself. Okay, like if we need some data from database, so APN itself can test the data from database. Okay, if there is any manipulation needed, like I'm asking user to fill the details, okay, of salary and system is calculating the income tax. Okay, so in that case, we will use a script task, right, because user is just inputting the data of salary or, you know, the all of the income, but system will calculate the income tax. So that calculation will be in script task. So script task is a task that is completed by system itself. Okay, there is no any user involvement in this. So that for that purpose, we use the script task. So if there is any data calculation needed, or if then if we need to pass the data, if we have to perform some of the activities where user input is, you know, sorry, user, user requirement is not there. So we use the script task. So to check the property of this one, I have to click double click on this. And you can see we have similar general take here, where you can define the name, description, task display name is similar to the process display name process display name is also dynamic and task display name is also dynamic. So whenever an instance is running, so that every run will also at no creating new instance. So for that it will have the need. In data, we have input and output. Okay, so in input, we can define the variables, okay, and then output also. So in input, whatever we variables we are creating, these are local variables, okay, similar to interface. So these local variables we can use in this not only if I create a local variable in this script task, and I want to use that local variable in this node, I cannot. Okay, I can use process variable anywhere in the in this complete process model, but cannot use the local variable that local variable that we create from this new input, we call as activity class parameter. Okay, so if I'm creating suppose employee ID here, that is number integer, okay, I can use only in this particular node in input or output, but I cannot use in the different node. So in value, whatever value I want to assign to this employee ID, we use in value. Okay, if I'm in this one, this is a edit, you know, expression editor, where we can call the you know, expression rule as well. Okay, or we can do calculations like if I want to calculate something, I can do here like if I want to calculate eight plus nine or something, or dynamically, I can use this expression editor. And if suppose I'm calculating something so that calculated value will be stored, you know, will be stored in this activity class parameter. Okay, and that activity class parameters value I can save into process variable as well. Okay, so in saving to we use process variables. And in the name is the activity class parameters. Okay, this activity class parameters, we can use in output also. So input run when node, you know, start to execute and output run when node, you know, completed the execution. Okay, so it running start and it running end. And we can create multiple input also here. Okay, similarly, we can create multiple outputs also, okay, from here. So if I want to configure the output, I have to click, I have to click on this one, then it will come and I have to click here in this expression editor. And here also I can write, you know, any data calculations, or and data manipulation. So if I want to pass the data, then also I can use this like if I want to create code any of the rule, then I can call the rule from here. Okay, and I can pass the parameters. Same like we are calling the rule into interface, we can call the rule or into process model as well. And we can pass the process variable value or activity class value into the interface or expression rule. Okay, and we can save this into the process variable from here. So like this, we use the input and output. So in input, we create the activity class parameters, and we can calculate the data. And in output also, we can do some calculations or we can manipulate the data, we can pass the data and we can store into the particular process variable. If I want to delete a particular output, I have to select and click on this one. So like this, we use the script task. Okay. So in the script task, we do not configure any interface, but we define input or output to manipulate or calculate the data. Now, this is user input task. Okay, user input task, where we define the form. Okay, so we can call any of the interface that we created. Okay, and we can so we can pull that interface from in this form type. So in general, a general type is similar to other types or other nodes, like in name, we define the name of the particular node, like if I want to get the employee information, so I will give the employee information name. Okay, I give the description task display name is again it is a dynamic name. So we create is a dynamic. Okay. And then we define the task priority. And if I want to create a quick task, the task is the task that do not display into the task that you know that in our first day, we check the there was a tempo, right, interface and there was a task that so if I define this one as big task, this particular interface that I'm configuring here, okay, want display in on this task type. Okay, similarly input and output we define here. Okay, like if I want to create input, I can create input if I want to create output I can create from create the output from here. So suppose if I want to pass some variables value into the interface, okay, or if I want to get some values from user from the interface, so I create the input. Okay, so suppose there is an interface that have two variables employee name and employee ID or a variable of CDT type, then I will create that input of same type. Okay. And that input, we can pass through to the interface. So from here, we did, you know, we call that interface, right. So suppose it came like this is an interface, right, that we created last time. And if I want to call that interface, I can click on this directly. Okay, and I will click here on search. I will search and I will select. Okay, now I will keep on. Okay, and it will ask it is asking, do you want to automatically create not input or not inputs are activity class parameter local variables to match your interfaces input. Okay, so it will automatically create those activity class parameters. Okay, so on that interface, we have two rule inputs, right, selected country and button value. So it is automatically created the activity class parameters and configured here. So mapped also. Okay, so it was the text type entities also text type, it multiple selected country and button value is multiple a single type. So it automatically created the activity class parameters and map in the perspective field. So these value part that is right side is the activity class parameters and left side the interface parameters. If I check from here data, so you can see activity class parameter is all already created automatically created. And you can check that button value also. So button value is also automatically created. Now, if I want to save this particular value that user will input into a particular variable, I have to create that variable. So I can create the variable from process variable from here, or I can create from property there also right that we created last time. So from here also I can create the variable, like if I create the selected country, for connection, like this I can create. And I can use this one. So if I want to, because, suppose I want to use the user info info information into next node, I cannot use this AC, right? That's why I have to save this into process variable. Because process variable we can use anywhere. Okay, like this we save. Now there is one tab that is assignment tab. Okay, so if I want to assign the particular interface to someone like suppose, there is a prover, okay, a prover interface and a prover interface I want to assign to the line managers group. Okay, so I will use that if I want to assign to the user who is initiating this, I will I have to use there is one function process initiator. Okay, so if I use this process initiator in that case, it will assign the task to the user who is running the initiating the process. Okay, now I can go and I can save and publish. There is one error. I think that there is an interface. Okay, so if I go and check the interface, this one, if I simply configure this section on this button one, I can save this value into rule input, like selected. We do not have any variable for this question, but we have variable for country. So I can use this one. So now, and this one, I can make it as not required. In this one value, I can use selected country or isolated country. Okay, and in saving towards them, I can do the same. So we are using this local because we do not have any local even now. So I can simply remove this. There are some error interface that we will check. And I can configure the new interface also. So now I will open this one. So that this is interface. Now I will create an interface user details. Okay, so like, similar to other interviews, I am creating this one, it will create an interface. It interface for me. Suppose I'm creating the same variable here, that selected country. Okay, and text type, it is multiple type. Because in process model, we create multiple type and button value, that is also text to it like this. And in this, I can have one drop down label countries, in choice values, I can put two countries. Secondly, choice levels, right? In value, I can use this variable, I selected country. And in saving towards them, I can use I selected country. Okay, now you can check its type. Those are but where you are null, and India is working. So I can have the test. Okay, this one, I can have it. And I can define that placeholder, like select a value. Now, if I select this one, it will have the value of 20. And like this interface, I want to go into the process model, I have to go here. Okay. And I can clear this one. I can go to search. And I have to just put this one. Okay, and we'll select this one. So now it is again asking me to create the variables. Okay, so I can select this one. But this is multiple type, right? Last time it was multiple type. That's why it is not coming into the choice. Okay. Now, this is single type. And if I select, you can see now it is here. Okay. And this process variable is also multiple type, right? So this one also, I have to change that single type. Okay, so it is automatically single. Now, if I publish this one, so there is some error. I think the error might be in the name that you defined, right, in the display name or somewhere. Okay, so like this, you know, there are some error coming. So, but once it is saved, okay, like this, so you can see here, it is saved, right? And it is defining the error that ample information at output input expression. But, you know, one, to debug this one, I can go to this file, and I can debug. Okay. And once I have, I debug this one, I, I can ask you to fill the information. Okay, so like this, we define the user input task. There are some events also here. Okay, like a start event and event. Okay, so these are events. Okay, like this, we have other events also that we will discuss in later sessions, or I will give you the link of the documentation. There are some gateways, okay, that we will generally use. Okay, so like this is absorb gateway, this is or and and complex, right? So these are four gateways. So absorb will use most of the time. So in absorb, we will have like, there will be one input and multiple output, but at the time only one output nor, you know, path will be executed. So suppose there are some conditions, okay, on basis of conditions, I want to go to different different parts. So like I can say, after submission, okay, after this interface, I put if I put this XOR, okay, and an example. Okay, like this, if I want to write the data only in case of user submit the form, okay, if users simply fill the information and cancel the form, at the time, I do not want to store the data into database. Okay, so it's depend on the choice, right? Whatever you just, you know, choice, take the choice on the interface. So in this one, we define the conditions here, like if the button value is submit, then it will go to write, if the button reaction value is not submit or anything else, then it will go to n node. So if first condition is true, okay, it won't check the second condition, okay, and it will execute that path. So in this one, at a time, only one output path will be active. If this condition is false, then it will go to the second condition. And if this is also false, then it will go to the last one. But if any of the condition is true, it will execute that path. In OR, it check all of the conditions. So suppose there are three conditions, so it checks all of the conditions. So if this is correct, it will go to this path, then it will take this path also. Second one, if this is correct, then it will go to this path also. So it will execute the multiple path, okay, wherever the conditions output is true. And it's like, it have multiple inputs, input path. Okay, so suppose there are two input path coming from to this particular one, like one from here, one from, I can just take the example, like one from here, and other from here. Okay, so there are two input path coming to this one, one from here, and other from here. We do not define any parameter in this end and gateway. Okay, so if these two paths are coming to here, okay, this end, so it will only completed when both of these paths are on this node. Okay, so suppose this path is executed on this end node, but this path is not on the end, so it won't run further. Okay, it won't go to the next node. It will be on end only. So, and gateway hold the process until all of the path, all of the parts which are configured are completed. Complex in complex we can have multiple condition at same time. Okay, like if I want to execute only one outgoing path, if I want to do one or more outgoing path, okay, or require some you know, incoming parts, okay, like suppose I want to configure that there are three input path, but I want only two input parts, okay, required to be, then I can configure like this. Okay, so these are gateways that we will use to put the condition or to divert the path. We already checked like how we can save the process model, we can save from here, but it won't create a new version, it will just save the information. Okay, but if I'm clicking on save one public, then it will save into the executable form and it will create the new version. If I want to load the older version, I have to just click on here. Okay, and I can see all of the older version have here, I can click any of the version, any of the version and I can click on load. Okay, so it will load the older version of the particular process model. Okay, smart services are like, you know, that these are smart services, or we can say process model, these are like redefined, okay, like functions, in interface, we use the functions, right, so in process model, we call functions as a smart service, okay, that is defined, you know, designed with the help of plugins. So if I want to delete some records, I can use this smart service, if I want to query into database, I can use this one. So similarly, we have a lot of smart services, some smart services like out of the boxes, smart services that we can say out of the box functions, that if you directly provide and some are customized, okay, smart service or design advice, you know, a particular organization, okay, so that is customized. So we will use these smart services whenever we have requirement, okay, like if I want to write the database, write the data into database, I will use this right to data store entity, there are other purpose like if I want to create some document, I want to send the email, I will use this one. So similarly, there are multiple smart services for different, different purpose, okay. So these smart services, you can go through one by one. But first, we have we should learn about all of the properties that process model have, how we can configure this script task, how we can configure the user input task, and how we can define the other properties. So like this, we have should learn first. So today, we covered another basics of process model, okay, like in high level, what is process model? And we did, we discussed about some property, some events, some gateway script tasks, okay, user input, how we can take the input from user that we discussed how we can configure the interface to the process model, how we can put the conditions, okay, the whole things we will discuss, we will continue on process model tomorrow, like we will configure a particular interface and we will store the data into database, okay, with the help of process model, so that we will configure tomorrow. But if you want an instance for practice, you can fill the details on this Google form or you can put the comment on Telegram channel as well. If you have any other question or any other query you can put on Telegram channel and in this email as well, that is training the code master.com. So thank you. I want to hand over to Sanjay sir. Yeah, thank you, Ankit, for sharing all the knowledge. And I think it was quite interesting because I was able to see some pictorial representation, I was able to relate Salesforce, because in Salesforce, also we have flows where we implement some processes. So yeah, so it is interesting. And if guys will be doing some practice, so I think they will be able to learn more. And tomorrow I think you will be covering more examples. Yes. Yeah. Okay, thank you everyone. So those who have joined live, thank you. And those who are watching the recording, thanks to you as well. So please share your feedback about the bootcamp. And thank you, Ankit, for sharing all the knowledge. Okay, so ending the session. Thank you, everyone.


The future. Ever wonder what it's going to be like, 20, 30, or even 40 years from now? Hello, and welcome to FuturePath. I'm Amariko Forresteri, Director of External Affairs at the NASA Lewis Research Center in Cleveland, Ohio. In the future, we all know our clothes will change, our hairstyles will change, and even the music we listen to will change. But how will the technology that's being developed today affect our lifestyles in the future? For a long time, NASA has been concerned with developing aircraft that will fly further, higher, and faster. But more recently, our concerns has changed to flying aircraft with greater fuel efficiency and protecting our air quality. NASA is developing a propulsion system which involves both the jet engine and advanced propellers. It's called the Advanced Turbo Prop System and shown here. The Advanced Turbo Prop Project combines the efficiency of the propeller with the power of the turbine. This technology base provides for the future development of the single-rotation and counter-rotation Turbo Prop propulsion systems. The idea is to reduce fuel consumption in both military and commercial aircraft. The initial concept for the Advanced Turbo Prop System first came about in the mid-1970s due to the OPEC oil embargo and the sharp rise in fuel prices. The fuel burned in a 727 or 737 jet aircraft can be reduced by as much as 50% with a propeller-driven aircraft. Advanced Turbo Prop propellers are very different from traditional propeller designs. They are very highly swept and very thin. There are 8 to 10 blades rather than the 3 or 4 blades that we are used to seeing. We therefore get more power in a smaller diameter. It allows us to fly faster, up to 600 miles per hour, and at a much higher altitude, around 35,000 feet. The noise levels of this new Turbo Prop are much less than the traditional propeller or Turbo Prop aircraft. There have been three series of flight tests in the Advanced Turbo Prop project. One, the NASA GE Boeing flight tests of the counter-rotating unducted fan on a B727 aircraft. Two, the NASA Lockheed Prop Van tests of a single rotation Advanced Turbo Prop on a Gulfstream II aircraft. And three, the GE McDonnell Douglas tests on an MD-80 aircraft. These tests verify the readiness of the Advanced Turbo Prop project for commercial engine development. Another way NASA is helping the aviation industry to a more efficient future. Another form of a propulsion system is the diesel engine. When you think of diesel engines, you probably think of certain types of cars or heavy trucks barreling down the highway. But technology developed by NASA is currently creating breakthroughs in aircraft diesel engines. NASA is also designing remarkable improvements for diesel engines and trucks. Enthusiasm for the development of diesel engines is reaching pre-World War II levels. That's when diesel engine technology was very popular for its endurance and altitude records set on long-distance flights. Although the war halted further development of aircraft diesel engines, work on the engines continued again well after the war. The United States Army is developing and designing diesel engines for helicopters. Various industries throughout the world are planning to develop aircraft diesel and diesel engines used in heavy-duty trucks are being improved upon by the Department of Energy. Diesel engines are primarily used when high power is needed and fuel consumption and durability are of concern. Trucks, stationary power plants, large ships, even tugboats use diesel engines. A man who sees a bright future in diesel technology is Mr. William Wintucky. Mr. Wintucky, who has done much research on aviation diesel, is involved with a number of projects at NASA Lewis Research Center aimed at improving diesel engines. Joint research is underway involving NASA and the Department of Energy to make diesel engines more fuel efficient. Technology to redirect fuel exhaust back into the engine could result in reduced fuel consumption of long-haul trucks by up to 30%. Mr. Wintucky explains the difference between diesel engines and gasoline engines. A diesel engine is basically the same as a gasoline engine except for the combustion process. The difference in the combustion process is that as the fuel is compressed by the piston the temperature is raised to a point where ignition is started by the heat of compression from the piston. In the gasoline engine the combustion is controlled by a spark plug and ignition is controlled when you want it started by an electrical impulse which discharges through the spark plug. In the case of the diesel engine when the fuel is raised to its auto ignition temperature the fuel ignites throughout the combustion chamber at the same time and therefore the pressure rises very rapidly just like an explosion and as a matter of fact is an explosion and that's why sometimes when you hear a diesel engine going down the street and it sounds like it's knocking you are actually hearing the explosions of the combustion process. Because of the explosions or very rapid pressure rises in the diesel combustion chamber the walls of the chamber have to be thicker and also the bearings have to be larger. Overall the engine must be much stronger to design for the explosions. Why develop better diesel engines and why create one for aircraft? Diesel fuel which is oil can be produced from a wide variety of sources such as of all things sunflower oil or peanut oil. Also diesel fuel is safer because it does not ignite on its own. Absence of an electrical ignition system eliminated radio interference another safety factor for aircraft diesels. The desire to use the fuel efficient diesel engine in aircraft is not new. The interest in aircraft diesel engines goes back as almost as far as internal combustion engine gasoline engines dating back to 1911. The main reason that diesel engines were considered for aircraft use very early on was at that time all of the gasoline engines were carbureted and one of the main problems that aircraft had was icing and with diesel fuel since the fuel was injected directly into the cylinder there was no problem with carburetor icing or ice forming in the carburetor stopping the fuel flow and of course stopping the engine. A second and almost important reason was the fact that diesel fuel does not auto ignite which was a problem in the early days of aircraft. Auto ignition is the process where the fuel ignites spontaneously or without any external source. In the case of gasoline, gasoline vaporizes very easily and the vapors are very combustible. With diesel fuel, diesel fuel does not vaporize very easily and stays as a liquid so therefore it is a much safer fuel to use. The diesel or compression ignition engine was first designed by Dr. Rudolph Diesel of Germany. By 1897 the first commercially practical diesel was put into use in the form of an industrial engine. About 1910 the heavy slow speed diesel engines were replaced with higher speed lightweight engines which provided a major step toward aviation diesel use. In 1931 the nine cylinder Packard diesel built in the US set and still holds the world diesel flight endurance record of 84 hours and 35 minutes without refueling. Credit for originating the diesel aircraft engine is given to Germany's Dr. Hugo Junkers. Dr. Junkers was interested in development of a diesel engine to power commercial aircraft. At the time there were no transatlantic flights because gasoline powered aircraft could not carry enough fuel to cross the Atlantic and still have enough room left for payload and the diesel engine was the only engine at that time known to have the fuel efficiency that would allow transatlantic flight and still have room to carry either mail or payload. So in conjunction with Lufthansa the Junkers Jumo engine was developed and installed on a number of flying boats which Lufthansa entered into transatlantic service from the Azores to South America in 1936. The Jumo continued operating until the outbreak of World War II when production turned to the more easily designed and constructed gasoline engines from military aircraft. The British developed the last major aircraft diesel engine which used a turbine to give it more power. Mr. Wintucky gives us some insight into the most fuel efficient engine ever flown. British Napier Nomad engine was very unique. It was really a very high performance turbocharger in that the exhaust gases from the engine the diesel portion were ducted into a fan-like turbine which then drove the compressor which compressed air and put it into the inlet of the diesel engine. This raised the overall pressure in the engine and allowed it to produce more power for the given size of engine that it was. And in many cases engines will produce two, three and even four times as much power when turbo charged versus when they just have a carburetor on them as would be in your normal automobile engine. Turbocharged diesel engines for aircraft are making a comeback. NASA research has inspired the US Army to develop the technology to use diesel engines in helicopters. Early in the 1980s the Army did a number of studies in looking at engines for light helicopter use and they found that through the use of a very highly turbocharged diesel engine they could get an increase of up to 50% in range or a payload that a helicopter could carry. And since for the Army fuel represents up to 70% of the amount of supplies that has to be transported to the battlefield a 50% savings in fuel or a 50% increase in payload represents a tremendous savings to the Army and a reduction in a logistics problem. So the Army was very much interested in the use of the diesel engine to lower part of its fuel requirements. The Army really took the expertise that NASA had developed during the time that it was looking at the aircraft diesel engine and is now using this expertise in its own program. The engine being developed by the Army for helicopters is expected to be operating by the mid-1990s and work is being done to develop materials and lubricants able to withstand the high temperatures, high speed and high pressure of an aircraft diesel engine. The oil that you use in your car runs at the most about 350 degrees Fahrenheit whereas in the engine for the helicopter we're talking about running as high as 800 degrees Fahrenheit. There is no oil now commercially available that will withstand these temperatures. There are lubricants that can operate at these temperatures but they cost thousands of dollars and the goal of our program is to develop new lubricants that will be economically feasible and operate within the temperature limitations that are required to produce the power for this engine. It is hoped the United States Army's efforts with diesel technology will result in a safer more fuel efficient and economical helicopter fleet. The diesel engine's low fuel consumption feature is valuable to countries such as Italy and Japan where fuel is very costly and also to the USSR where long-range flights abound. Decades ago scientists were able to see the promise of diesel engines in aircraft. The previous work is the firm foundation on which today's research can stand. Research that NASA and people such as Mr. Wintucky believe is important and could result in 21st century aircraft diesel engines. Now let's talk about another engine you've probably never even heard of the Sterling engine. As part of the work being done in today's dynamic aerospace industry NASA Lewis Research Center is further developing a rather remarkable engine which was invented surprisingly way back in 1816. Named after Robert Sterling its inventor the Sterling engine very well could be the most exciting and efficient new type of energy conversion device in space within the foreseeable future. Already the engine has been developed and tested successfully as an automotive engine using less fuel than the car engines we use now and the Sterling engine can use a variety of fuels gasoline diesel fuel alcohol kerosene and others. During this report though we will explore this fascinating engine in its possible uses in space. Logically we begin by asking how does the Sterling engine work? Simply put the engine works because of a difference in temperature. One end is kept hot while the other is cold. Within the engine a displacer piston moves gas from the hot end to the cold end and back again. As that gas moves its pressure changes. When the pressure is high the gas pushes against a power piston causing an output of energy. Since the heat input is supplied externally anything that will burn or make heat such as solar or nuclear power fossil or gaseous fuels or even garbage will make the Sterling engine run. NASA is working to develop materials that can withstand extremely high temperatures to be used in the construction of the Sterling engine. There are two kinds of Sterling engines the kinematic and the free piston. The free piston shows the most promise as a source of electric power in space. This concept is relatively new approximately 25 years old. In their basic form both types have a piston and a displacer. In the kinematic engine the piston and displacer are connected to other parts of the engine but in the free piston the piston and displacer are not physically connected to anything and move solely by forces and pressures within the engine. At NASA's Sterling engine project office Jim Dudenhofer special project manager had this to say about the Sterling suitability for use in space. So we have gas bearings to eliminate friction and wear. We have a totally hermetically sealed unit which helps us with gas leakage and permeation in the long term. Bear in mind we're talking about an engine when we talk about space that must live out there without a mechanic for anywhere from 7 to 20 years. And so long life and good maintainability are essential for a space power engine. NASA Lewis Research Center continues its work with the Sterling engine as part of a project called the Civil Space Technology Initiative. The purpose is to develop various technologies for future use in space. Until about 1985 there were free piston Sterling machines that could generate only a maximum of three kilowatts of electricity. NASA in trying to increase power output developed with mechanical technology incorporated a 25 kilowatt electric machine. Now NASA is trying to find out how much larger Sterling engines can be made. Initial studies indicate power levels as high as 500 kilowatts per machine and possibly even higher. And finally why develop the Sterling engine now when already power has been generated in space in other ways for years? Jim Dudenhofer answers. Space technology is growing by leaps and bounds and instead of needing hundreds of watts in space we are now are going to be we're on the threshold of needing millions of watts. If we're going to colonize Mars, if we're going to colonize the moon, if we're going to manufacture in space we need tremendous amounts of electrical power. Photovoltaics simply become too large. The great big solar panels that we're all accustomed to seeing simply become too large. They're too difficult to move. They have some limitations in polar orbits because of the problems encountered with the Van Allen radiation belts. Solar dynamic machines of which Sterling is one can operate any place that there is a source of heat be it the sun, be it nuclear. A Sterling engine once it's supplied heat can function and it can produce large amounts of electrical power output in a relatively small and lightweight package. And that's our purpose for being involved in this type of technology development work. The amazing Sterling engine, one of the most efficient heat engines made and just one of the many technologies being developed today at NASA Lewis Research Center. Now that we have a background on understanding how the Sterling engine works let's view a short animated piece on the development of the Sterling engine for its use in space. The free piston Sterling engine effort is directed at high efficiency, long life and a high specific power to meet NASA's needs for future space missions. The successful tests of the 25 kilowatts space power demonstrator engine at 650 degrees K in 1985 completed phase one. Phase two of the three phase Sterling program is now underway leading to the design, fabrication and testing of a 1050 degree Kelvin super alloy Sterling engine. This is one of several conceptual designs. The successful development of the 1050 K experimental Sterling engine provides a low-cost basis for the low-risk future development of the phase three refractory alloy 1300 K engine. It will also provide a variable alternative power conversion system for an early flight demonstration of the SP100 nuclear space power reactor. The performance objectives of a typical single cylinder design are alternator output 25 kilowatts of electricity engine efficiency 30 percent inlet temperature 1050 degrees Kelvin outlet temperature 525 degrees Kelvin working fluid helium engine alternator frequency 90 Hertz specific mass 6.4 kilograms per kilowatt of electricity operational life over seven years. With lessons learned in the 650 phase one engine program the super alloy phase two engine is being confidently designed for high performance and long life with current nickel base super alloys. The free piston Sterling engine achieves its high performance in part due to its simplicity of design and operation. Its major features are the heat exchanger assembly which will have only 40 heater cooler modules to significantly reduce the number of welded tube joints. The displacer one of three moving parts is a 5 kilogram piston floating on a film of helium and shuttles the working fluid from the hot expansion space to the cold compression space and vice versa. The reciprocating action of the 12 kilogram power piston caused by the working fluid produces electrical power in the linear alternator. The 12 kilogram balanced piston oscillates to fully counteract the combined vibrations of the displacer and power pistons. Alternate engine designs employ opposed sets of pistons synchronized to eliminate the need for a balanced piston. Magnets in the power piston oscillate through the stator laminations to produce alternating current. The pressure volume diagram shows the cyclic variation of pressure and volume in the working space between the power and displacer pistons. The area enclosed by this diagram is indicative of the engine's thermodynamic power. The following computer generated animation shows relative motions of the three pistons. For clarity their speeds have been greatly reduced from the normal 90 cycles per second operating frequency. We hope you've enjoyed our program. I'm Amarico Forestieri hoping you'll walk with me again along the future path at the NASA Lewis Research Center in Cleveland, Ohio.


Derek Rose, who is best known as the superstar professional basketball player for the New York Knicks and the NBA, has managed to snag some pretty luxurious real estate in California and formerly Chicago where he started his career. During his time with the Chicago Bulls, Rage snagged a swanky three bedroom four bathroom condo near the top floor of Chicago's Trump Tower that he fell in love with while staying at the hotel for three weeks.  This 13,000 foot residence that features an infinity pool and panoramic views of Los Angeles is a showstopper. Ladies and gentlemen, this is a house tour that you do not want to miss. In these videos, we don't reveal any real addresses and even though we've done house tours of our own, please do not show up at any private residences because it's not safe for anybody. Derek Rose has had quite the lucrative career, killing it in professional ball, garnering a net worth of $90 million and currently earns the veteran minimum NBA salary of $2.1 million per season. However, in this peak, he earned $21 million playing for the Knicks. In a typical year, he earns $12-15 million from endorsements alone, most notably that lucrative Adidas deal. After being drafted by the Bulls in 2008, Rose signed a shoe deal with Adidas for $1 million a year. In 2012, he signed a deal with Adidas that ultimately could be worth $185 million. He has also signed deals with Wilson Sporting Goods, Skull Candy Headphones, Powerade, Force Factor Sports Drinks, and a suburban Chicago Nissan dealership. Now while he was making bank playing pro ball, he managed to snag that big ticket with Adidas. Some of the notable deal insights include $185 million overall deal value over 14 years, an agreement that Adidas pays him at least $12 million per year. In addition, he has given an additional $5 million per year for appearance fees and access to a private jet for transportation. Rose could earn up to an additional $6.5 million per year in royalties based on sales. Adidas contract pays Derek's older brother $250,000 per year as a consultant, while the contract pays his childhood friend $75,000 as a consultant as well. Derek Rose sounds like a pretty good friend, taking care of his brother and his childhood best friend. Good thing that he got that ticket inked because 64 days after signing the contract, Derek tore his ACL and has never been the same. Needless to say, Rose has enough money from salary and endorsements to last him a lifetime. And I've gotta say, some of these homes that he's owned are pretty sick. What's going on guys, it's Clyde Smith, and today we're bringing you another house tour right here on Famous Entertainment. Now I did notice about 95% of you watching aren't subscribed, so be sure to hit that subscribe button because we drop a new video daily. If you like these videos, ring that bell for notifications, follow me on the gram, and as per usual, let me know who's house tour is next down in those comments below. Alright, let's get into this video. Fresh off becoming the NBA's youngest MVP, Rose had splashed out $2.8 million for a three bedroom, four bathroom condo near the top floor of Chicago's Trump Tower. The 84th floor, 3,000 square foot unit is located in the 92 storey near Northside building. It offers panoramic views of the city, including both the river and Lake Michigan. Rose claimed that he fell in love with the place during a three week stay at the hotel. It's definitely an unbelievable feeling just being up there. The view is nice, and I don't take it for granted, it's a blessing. Rose financed the purchase with a $1.7 million mortgage and eventually purchased the one bedroom unit next door. Knocking down the wall in between them and expanded his space into a bigger, more open floor plan. Decked out with elegant mahogany wood flooring, the living room features floor to ceiling windows that boast a stunning view, enormous white columns, and a cozy fireplace. The kitchen is decked out with stainless steel appliances, an electric stove, marble countertops, and an island perfectly centered in the room. By the looks of it, there was ample storage space in the custom cabinetry and the island.  Rose's master bathroom features dual sinks, two large standing showers, and a colossal soaking tub perfectly centered between the two, perfect for relaxation. The Trump Tower is the second largest skyscraper in Chicago, and the residence is filled with a number of lux amenities. The residence features arguably downtown Chicago's most exclusive rooftop, restaurant, and bar. The residence at the Trump is a posh outdoor lounge space that features extraordinary views of the city while serving glamorous refreshments and cocktails that are ideal for warm summer seasons. The mezzanine level of Trump Tower Chicago is the unique and stylish rebar lounge, which features downtown's best specialty cocktails perfect for an after-work social gathering or a fabulous night on the town. Also located on the 16th floor is the glamorous 16 restaurant, a Michelin star-rated dining experience that's among the best in the city. The Trump Tower residence also features a private pool looking out to the city from 14 floors up. The pool was 75 meters in length and features three full-length tap lanes. Additionally, guests at the pool enjoy available dining services while they relax poolside. The fitness center features a spacious and bright space that overlooks the Chicago River, and comes complete with free weights, resistance machines, and all the best cardio equipment to help make getting in your daily exercise a thing of luxury. Possibly the most glamorous spot in the residence was the spa at the Trump that sparks 23,000 square feet and boasts 11 spa treatment rooms, making Rosa's relaxing experience a thing of beauty and can include anything from massages to facials and relaxation programs and beauty treatments. Rosa's next big real estate purchase was a stunner, as the home features over 13,000 square feet and boasts eight bedrooms and nine bathrooms. The home features a resort-like sanctuary with three distinct structures, including a main residence, wellness center, and guest house that was used for Rosa's Adidas commercial, Basketball is Everything. The home features floor-to-ceiling glass walls and clean edges and an outdoor entertainment area on the elevated patio deck. Let me tell you guys, this home is absolutely filled with luxurious amenities, including a private screening room, perfect for going over game day footage. Rosa's gymnasium that puts regular gyms to shame in his very own wellness center that comes complete with change rooms, jacuzzi, and steam rooms. In addition, the home features a parking lot for up to 25 people. So we're willing to bet that he's thrown a few team parties at this residence and a wine cellar that comes complete with a wine tasting room. One of the most lavish features of this house includes the easy in and out floor with retractable walls, but we'll get to the outdoor area in just a minute. The home features a number of glamorous living spaces that come complete with a profusion of lavish furnishings, abundance of cozy fireplaces and custom fixtures and fittings throughout. One living space connects to the pool area and features a sleek kitchen that comes complete with stainless steel appliances, marble countertops and an elegant island perfectly centered in the room. In addition, Rosa's home features a butler's pantry that's basically the size of a basketball court. Rosa's master bedroom features a profusion of sleek furnishings, fireplace, flat screen television and private access to the rooftop entertainment area.  Perfect for relaxation. As glamorous as the interior of the home is, the backyard features a glamorous infinity pool and spa, outdoor barbecue and bar and kitchen with fireplace and entertainment area. In addition, guests lucky enough to visit can take the party to the second level patio deck with panoramic views of both the rolling lawns and California landscape. All right, so I think I'll bring this house tour to an end right here. We got to take a quick look at Derrick Rose's homes and that new dig that he picked out in Los Angeles. After seeing that fancy little abode he snagged, what did you think? Was it everything that you'd expect out of Derrick Rose? I mean, personally, I'm a huge fan of that backyard in Los Angeles. I mean, an infinity pool can't go wrong with that. Out of all the features in Derrick's home, which ones were your favorite? You guys can even go ahead and let me know in the comment section down below. My name is Clyde Smith, and I'll see you guys in the next video.


Wednesday woke up having this mixed very smoothie for breakfast So we're filming another episode for dive today We're also gonna have a photo shoot since it's a new season with our new guest So I have to go to the shop to get my hair makeup done and I figure that I would cut my hair today I'm gonna go back to a short bob because my hair right now Gosh focus focus focus focus. Hello. Oh my gosh Okay, I want to cut it one last time before I start growing it out again Professional took me a year to do it. She doesn't have five seconds Are you satisfied? Yeah, you're higher If you want to put do one where you like Good morning guys, I am about to go hit the gym. I'm in the Super comfy airy lightweight Soft t-shirt from Yjack. Yes, they are the sponsor of today's video. So thank you so much to Yjack So I'm going to spend my day wearing different Yjack shirts and telling you a little bit about them. But for now, I am going to go work out. I Have changed into another Yjack t-shirt same style but different color Yjack is a company that creates basics for men and women And what separates them from other brands is that they manufacture this specific type of cotton called Xfina Xfina is a cotton that's made with extra long staple cotton yarn Which is the highest grade yarn with only 8% of the entire world's cotton yarn production. It's so smooth Silky, it's very elastic and so lightweight and cooling. So it's Perfect for the summer. You can just recognize how good the quality is by just the fabric So I just showed you guys this basic round neck t-shirt But they have many other styles on their website boat neck boxy tee v-necks Mock tees you have a lot of different designs to choose from these have been like my favorite basics these days Seriously, thank you to Yjack for sponsoring this video and making such comfortable Breedable t-shirts for me to live in they have both a USA website and a Korea website I will leave all the links in the description box below and you can use the code Ashley for 15% off your order at checkout It's time for a meal and I felt like it's been a while since I had kimchi fried rice So I'm gonna make kimchi fried rice one of the few dishes. I know how to make I'm also gonna cut these two spams So a secret behind these supposed spam looking things. These are plant-based pork from Omni pork They're vegan brand and they were kind enough to send me some of their products, and I'm finally Trying them out. I have my kimchi right here. They're so Fermented so sour just the way I like them It's so hard to cook in the summertime I'm sweating so much right now Thank you Kimchi fried rice I've ever made If you're a vegan, maybe try this out. It's called Omni pork. They started selling it on Market Curly That last few drops of sesame oil really Ties everything together. I feel like I Just love anything sesame sesame oil sesame seed sesame snacks Back from radio and yes, you guessed it. I'm in another wine jack t-shirt. I'm going to do my nails So going to the nail salon is very time-consuming and it can get kind of expensive So I kept seeing ads for this brand called Ohora Ohora Ohora and it's like semi cured gel so you stick it on your nail and you cure it a little more with the UV lamp and You get fresh new cute gel nails I went all out bought a bunch no regrets and I'm gonna do my nails right now I filed them into the shape that I want and I'm gonna put some cute nail designs on it I think I'm gonna go with this one But they have different sizes so you can choose what you want They give you two prep gels and they also give you a filer a stick used to remove I'm gonna use the prep pad first make sure there's no like oil on my nails I remember when I first started going to the salon to get my nails done It was like late junior high school and it was like high school and all we could get was a regular manicure and we had to Patiently dry them under the fan for like 10 minutes and be careful for like six hours after that just in case I But my fingers onto something or have to pee You know when pulling down the zipper pulling your pants down pulling them up and now Everything's so well made. You don't have to wait for your nails to dry They dry right away under this UV lamp. Of course, I'm sure it's not the best for the nails, but Once in a while should be fine. Okay, so I think the nail primer is dry Thicker than I thought.  I feel like my posture is getting bad Harder than I thought. I only did three fingers so far and it took 20 minutes Guys, I'm finally done with one hand. Hooray That took about Forty three minutes not bad considering that to get my nails done I do an hour round trip commute and getting my nails done itself takes about an hour and a half So 43 minutes. I think it's pretty good If I have something urgent the next day if I have like a schedule But I can't make an appointment at the nail salon I will use this if you especially enjoy doing your nails and doing like artsy stuff Then you guys will enjoy it. It does take practice I feel like you have to get used to it. My left hand definitely looks better because I did them after I did my right hand I wasn't very good with it in the very beginning, but when I was doing the left hand it went by super quickly so yeah, I like the fact that you can do your nails in the comfort of your own home and not have to worry about bumping into someone at the nail salon that might have COVID or something I don't really know how to take care of my cuticles. That's another con when you go to the nail salon They make your cuticles all pretty and nice and clean So it doesn't give me the same satisfaction as you know going to the salon and Looking at my hand after it's done Anyways, it was a fun experience I think the most important thing is how long will it last so I'll keep you guys updated about these self gel nails Okay, it's literally 12 a.m So I'm going to sleep now. It has been a long day. Happy Saturday everyone. I'm stepping out now I'm actually filming the girl talk part 3 with Joan and Subini today and I rented out a studio So I got to go out buy wine buy some snacks and head on over. I'll see you guys in a bit with Joan and Subini Okay, we'll talk about our favorite alcoholic drink. Wait nails. Oh my god. What are you going? Oh, hold on. You're wrong This looks like what I got done. I know right? I fell for their ad through YouTube Oh my god, I don't I didn't know it works. It works I'm not sure I remember the YouTube ads and chicken Yeah, you know what she was like, that's one of the 16 chicken ads that I've never seen before in my life Okay, grab this stuff on the island with Matt or me Oh yeah, I want to do that I want to do like one, two, three, okay, okay Let's do that one We finished filming and we came to a cafe Wearing this still I'm wearing it still She's still wearing it We ordered some coffee and some vegan gluten-free dessert Can we do like a quick cheers? Yes, cheers again Can we try the avocado cake? Yes, I'm really curious I was worried about this one too They pumpkin? No, I have faith in this one They pumpkin The avocado is really good Let's give a cheers I came back home, changed because it was way too hot And now I'm on my way to a studio More details a little later Well, you already posted that you're... So you could upload it It's, I don't know yet Okay But it will come out soon Thanks for having me Of course You did a great job Thanks, Sam I was either thinking of investing in a new camera Or a new computer But I thought the computer is more urgent Once I saw the colorful ones that were released I really wanted the blue one Or the mint one Or the yellow one I just wanted to see them in person and decide So I went to the Apple store But it turns out the one in Karoskir Only has three colors But me being the dummy that I am I bought a wireless keyboard while I was there Because I was like, okay It's gonna take a while for the iMac to come But I want the new keyboard So it's easier for me to edit on my laptop While I wait But if you order the iMac The wireless keyboard and the wireless mouse Come with the iMac There's no option to take it out Pay less money It's just included in the price for the iMac So now I have two Bluetooth keyboards I'm gonna have to sell one of them On Tangam Market I wish I could have double checked Before purchasing It's just that I went all the way to the Apple store And I was like, I have to get something That was on my mind So I was like, okay I've been needing the Bluetooth keyboard For a while So let me just get it I feel so dumb right now Anyways, you'll find out which color I went with In the next video Once the iMac comes And I can't wait to have a bigger screen So I don't have to like Be this close to the screen while editing But for now Please look forward to the Girl Talk video And episode number one for season two Of Dive Studios has been released So please go check it out And also look forward to My collab with Usong and his next album Thank you so much for watching Bye


The prevalence of malnutrition among cancer patients in Kenya is high, with 33.1% of patients being at risk of malnutrition according to the malnutrition universal screening tool, MUST, and 13.4% of patients having actual malnutrition. Additionally, 14.1% of patients have catexia, which is characterized by significant weight loss and low fat-free mass index. Smoking and age are both predictors of malnutrition and catexia, respectively. Furthermore, only 18.6% of patients have received any form of nutrition services. These findings suggest that there is a need for improved nutrition services for cancer patients in Kenya. This article was authored by L. Ukaduka, Z. N. Bukania, Waiipanga, and others.


In today's video, I am going to find the new Yu-Gi-Oh! Monster Box. I'm here at Walmart. It's late. It's 10.30, closing 30 minutes.  So I'm about to go in there, and I'm gonna find one. Just mark my words. We're about to do it right now. So, let's go. There they are. These things are gigantic.  These things are ridiculously large. Look how big this is. It is at, like, the pictures don't do it justice. This thing's like over a foot. It's like a foot and a half long.  I'm interested to see what's inside. The light just went off, so let's get back. Alright, guys. I officially found the new Monster Box. Now, as I mentioned already, this is the most ridiculously sized box of all time. As you can see, my gigantic head, it's three of them. I mean, it is very large. Another thing I noticed as I was going to look at this is, I'm not seeing any packs in here. No packs. Maybe? Okay, let's just take a look at it. You can't even see it. It's too big.  Before Monster Box, I don't even know what monster meant. It just meant another version of Mystery Box. But here, we have a monster-sized box, so it checks out. It's the battle edition. So if you're, I guess, dual edition, really, one structure deck, one play mat, one portfolio, one 50-count sleeve, and one card case. Okay, so none of that is a booster pack. So that's going to make this a little bit harder to have a video on, but we're going to open it up. I mean, it doesn't seem like there's any packs, but let's find out what's inside. I have two of these. I guess we're going to open both and then maybe give away some items from in here. It's going to be a very large package. And you guys know all you international people, you guys find ways to win the giveaways. So I'm going to end up sending it to you guys. It's going to be a box like this big. It's got $50 a ship that are something crazy. But yeah, we'll just, we'll give away like one contents or something like that. I don't know. We'll figure it out. But all you have to do, like the video, be subscribed, turn on notifications. Let me know down below. What do you think about these monster boxes, which are a monster size? I don't know. This is a strange box. It's a lot different than the normal one, so maybe it'll be good. All right. So two of these were $56.90. So keep that in mind. We're looking at what is the math? $28 each, a little bit more than that. A little bit less than $29, $2850, $2840, $2845. There we go. We figured it out. Something like that. So they were, I mean, not that bad for how big it is, but as you see, there's only a few things in here. So let's see if we get our money back here. We'll try to make our money back, I guess. There's no pack, so it's going to be a little interesting, but I'm going to have to open this over here. This thing is gigantic.  But when seeing these at Walmart, when I was walking in just from the door, I was like, I see them. That's it. There's nothing else that could be. All right. We're just going to have to go one. We're just going to have to do it over here like this. So first off, Play Mat. Okay. Wait, wait, wait. Did I see Elemental Heroes over? Wait a second. Elemental Hero. That could mean something. And by mean something, I mean, this would be pretty sick. We got an Elemental Hero Mat. So Elemental Heroes, Elemental Heroes, Elemental, wait. These are all Elemental Hero Game. Oh, I could have just read that. Elemental Hero Game Mat. This seems promising. I'm not going to lie. We got to open this up. We got to see. I mean, there's no packs to open today. So we got to, I mean, I think at least unless we get duped or something. But let's just see. What does this Elemental Hero Game Mat look like? It's got to be sweet.  Here's, okay. Wait a second. Okay. I love Elemental Hero Game Mat. That is awesome. Here's what I don't like is when the merch is just the artwork from the card in a square, put next to the artwork in another card in a square. If I'm Konami, I'm making some cool, like, you know, action shot of like Burst in a Tricks, Clayman, Sparkman, Avian, like all like up on here, like different, like not this exact same pose, like doing the same thing. I'm looking for some sort of like, you know, new artwork on this thing, not necessarily just like the squares. So while it is cool, it's also, I don't know. It feels like it could be better though. They do have some pretty cool ones as well. So I don't know. That's just, I think it's pretty cool. It's not bad. It's definitely a cool archetype. All right. Next item we have, okay. We have the portfolio. This is Dogmatica, Ecclesia, and the Fallen of Albaaz. There we go. Albaaz, Ecclesia, and Tribe Brigade. Where's the Tribe Brigade? I can't see it. So shiny. Wait, it's on the back. Oh, maybe it's on the back. So shiny. I can't even show you guys. Okay. Maybe if I go like this, I'm going to try not to hit the mic. There we go. There's the better look at that. So there's the binder portfolio, whatever you want to call this thing. So yeah, you have a, this is just basically an accessory monster box so far. Okay. Next we have a thing of sleeves. Okay. Okay. Now we're talking. You've won me over. Caribo Collection with Decay. Caribo Collection card sleeves. That's pretty cool. 50 card sleeves of Magikaribo, the legend. Okay. These are pretty sweet. These are pretty awesome. The Magikaribo, just rocking it right there. The Dark Magician hat on the Caribo, the Dark Magician wand. That's pretty sick. I'm a big fan. That's my favorite item so far. All right. We got two more items we have. Okay. Look at this. Elements of Hero card case. That's the skyscraper right there. The skyscraper card case. I'm not going to. Okay. What is this tape? Is this taped back on? What in the world? It looks like they just taped it back on. That's weird. Okay. But this is a really cool deck box. I'm not going to lie. This is, oh, that's good. Is that the Flame Wingman? Up there? Yeah. It looks like the Flame Wingman. That's nice. I'm a fan of this. I like this deck box. Hold 70 sleeved cards.  Wait, they're dice in there? No, that's the separator. Wait, if you played a 60 card deck, who's most people don't? You could fit your extra deck in here. Huh. Interesting. So if you're playing 60 cards, bad luck. Though, if you are playing, I just dropped it.  All right. Last item is our structure deck. And we got the Dark World First Edition structure deck. That's pretty sweet. Though now that I think about it, I think this is the new one. So I don't think you could even get a non-first edition version. But either way, pretty cool. There's a lot of, you know, of Dark World, of Dark World, of Dark World. Look at that. It's just so consistent because it's all of Dark World. That is a pretty nice looking structure deck. I'm not going to lie. I like the look of it. It looks cool. I feel like in a few years, I could see this one being like, it just looks like it would be expensive in about five years. But it probably won't be, to be honest. It'll get it like 50 reprints, but still awesome. And that's it. That's everything. But honestly, like, you kind of get a lot of value, like in terms of the merch. But the question is, if you're going to get the merch, why not just buy it separately? But maybe you did save a little bit of money. We'll have to see what the total was for that monster box. Maybe it was less than the 2845 that you would have spent with the bad intacts and everything. I said less. Maybe it would be worth more, you know? So it's actually worth it. You get a little mini discount. But the thing is, you don't really get to pick the ones you want. So it's like, is it worth it to get randomized ones? So maybe, maybe not. Let me try this second one. Let's see what we can get. Interesting product. I'll say that. It's definitely different, which is, I mean, I'm not mad. It's nice to see something different every once in a while. Though monster box used to be my favorite one because they had a great variety of packs. And then they kind of went downhill. So I said monster box. Wasn't it the one that had that terrible hidden arsenal chapter one as the cover recently? And then I guess this is the newest one. By the way, MJ holding down here. You can see a classic MJ holding. Yeah, it's always them. More products. Let's see what we get this time. Is there going to be any variants at all? Let's find out. That looks like that is an elemental hero game mat, which guess what? We have already seen this because it is the exact same. I don't know if we're going to expect different stuff or not, but we didn't there. All right. Item number two, come on. Give us something different. Do not be the Dogmatica Ecclesia portfolio. Please. It is the Dogmatica Ecclesia. The Fallen of Albas and the tribe brigade nine pocket dualist portfolio so far, which it is the monster box. There tends to be less variety in the monster box and they're continuing that here. We have yet another of the same portfolio. All right. We still got three more items. I believe there's going to be something different. Let's go. Let's go to sleeves. I would like these to be the same. They'll be different. Of course. Oh, they're not. Okay. Caribo collection. I do like the Caribo collection. I really like magic Caribo. It's pretty sweet. I'm not going to lie, but not any different. Two more items. Let's see if this deck is different. Let's see if it's taped. It feels like it is. It is the same deck box. Okay. So this doesn't necessarily mean that they will always be these, but our two have been exactly the same so far. So we're looking like it is likely you are not going to lie. I'm a huge fan of this deck box. I can't speak the deck box and the sleeves. I really like. Okay. Last item. Will it be a dark world structure deck? Hmm. Based on the feel of it. Just feel a little different actually. It feels like it's a little smaller. Oh, the site. Wait, is this a European deck? That's why it feels different. This is definitely not a USA deck. It's a lot smaller. Ours were super tall and a little bit thicker and a little bit maybe skinnier this way. No, man. Maybe the same. I don't know. This is definitely UK CA. Is that United Kingdom in Canada or is that just random things that just happen to look like UK? But I'm pretty sure that this is UK product. English edition doesn't really tell us that much unlimited. Okay. So we got a different deck. So it looks like the variety you can get is the decks, but unfortunately no packs in here. All right. And because there were no packs, I'm going to add a couple packs. I have my own mystery pack. First edition, not a majesty. First edition, soul burning volcano, soul fusion first dead and two extreme victory first dead. So let's open these up. Try to get starlight stardust. I got to open a couple packs for you guys. Monster boxes. Sure. They're fine. I mean, not something I'm going to buy again because it's all accessories. And to be honest, accessories are what I'm always trying to get rid of because they take up so much room and I just end up with a bunch of them. I'm like, I can't use all this stuff. So I'm always just trying to get rid of accessories, not get more. So yeah, not super exciting for me, but maybe if you are like, if you actually need like a deck box sleeves and a mat, you can get it all at once, which is actually pretty nice to be able to access that all at one time. So I only did three from the back. So that'll work. 10 dangle. Now we're looking for. So I do see some value in having that. But at the same time, it isn't that expensive. I'm really, if you think about getting the mat and everything that actually probably isn't a terrible value. What did I just open? I don't remember where the ghost would be. I'm going to do one for the back. We have battle box. It'd be really cool if we got a ghost rapid puncher. We have chief second and scatter shot. So we are over to soul fusion. We can get that colossus guys. That'd be pretty nice. It's a nice card. It is a nice card for big rumors about it. One, two, three. I don't know if this is a four because I don't open this set because it's in the age of death where there was no star lights, no oldies, no nothing. It was the highest car was a secret rare. So really boring to open unless you're trying to get that thunder dragon colossus. Here we go. And you're not going to get it there. Okay.  I did not get it. Two backs left extreme victory. We're back all the way in 2011. So 13 year old pack right here.  It took me forever to get it. I guess they're not mystery boxes. Monster boxes completely different. One, two, three. I don't remember the pack trick. I think it is the weird one. Let's do it real quick. Let's get the ghost. Sure. I've never gotten it before out of this set screen psychic witch rucks and special reboot localized tornado self momification mental seeker power up adapter psychic reactor psy beast and the mech lord army of whizzle. One more pack first day. Got to believe we can do this. You can make it happen. Last pack up today. Hopefully you guys enjoyed the video. If you guys would let me know what you think about the mystery boxes and don't forget to subscribe. If you enjoyed the video and want to see more like this or different from this can do all the stuff. Also, good. Check out poker rucks. I posted a new video recently. I really like it. I think it was pretty cool. It's a little bit different than what we normally do, but we're at 6500 subs getting close to that 10 game giving away a Nintendo switch on that channel when we hit there. So if you are interested in that, go support me on poker rucks. Seven ceremony. We have force resonator TGX 300. We have a buster blaster, not the buster blaster, the buster blaster even more intimidating. And a final card red dragon vase. So that was a little bit of a dud opening, but that's okay. Followed up an awesome product. Not a dud product at all. Okay. You could argue it was a dud product. I don't know. It's up to you guys on what you think.  The toe and foe show. Puff. It's a new man. Esther Deanna. America. Deutsche KK beats another side show. Ian Moosley Jr. Barney Robert F. Thomas. Blaine Changeling and Adele. So Galicia Jr. Thank you guys for supporting the channel and I'll see you guys in the next one. Peace.


Now, in the context of the next bullet which I have put here soil water air interaction most of the time what people have done is they have talked about soil water interaction. Any example? The whole classical geomechanics is based on the concept of soil water interaction. You start from hydrometer test, adiabatic limit test, consolidation test, direct shear test, permeability test, shear strength test, adiabatic limits everything is soil water interaction. What is then be added here is soil water air interaction, why, why air is required to be added here? Substances in it which may react directly with soil or it may react with water and it may have a different effect from soil, for example like sulphur attaches with oxygen it forms like sulphur, oxygen and hydrogen, sulphur and water, sulphur dioxide and water mixes and they form H2SO4 and they react with soil and they contaminate. Best example is Taj Mahal which has been which has been corroded by this acid rate. Correct. Ground water is in abundance, take the example of India only. How many places, can you put them, can you mark them on the map of the country that these are the places where ground water is in abundance or in other words do you think that ground water is scarce? It has been like there is a decrease of the ground water sources. Okay. Recently like. Alright, so it is becoming scarce day by day. Alright. Now the classical concepts of geomechanics are you always saturate samples to get some property, hydraulic conductivity, how did you do the test? Compact the sample in the mold, allow it to saturate overnight or 72 hours, 48 hours and so on and then do the test. Tract shell test, saturate the sample, then find out the shear stress. Consolidation test, saturate the sample, find out the characteristics. What is the meaning of this? These are the situations which you are simulating are practically not feasible. Why? I asked you the question how many places in the country have enough water? In other words, how many locations in the country have water tables which are going to saturate the entire soil mass which lies in the zone of interest of an engineer? Do you agree with this? Somewhere water table will be 300 feet deep, somewhere it will be 400 feet deep, somewhere it will not exist, somewhere it will be 100 feet deep. What I am trying to convey here is in a deceptive way is the classical geomechanics type of situation where you saturated the sample to find out its property are very very rare in nature. But what do you do? You get the properties in the laboratory by simulating a condition which is non-existent. Clear? In other words, most of these soil deposits are having three phases. They have air also, they have water also and they have solids also. And that is where you have to study the interaction of solid phase, water phase and the air phase if you want to understand this material in a better way. And then slowly and slowly you add the concept of contamination on all the three phases. So, you were talking about the solid phase, liquid phase and gaseous phase in a another word, another form. Soils may get contaminated with a solid phase, liquid phase or gaseous phase. Similarly, water may get contaminated with solid phase, liquid phase or gaseous phase. Similarly, air may have, of course it will not have solid phases, but it may have suspensions, it may have liquid phase of some other material in the air form or the vapor form and so on. So, once you put this system, I think it must be now clear that where the technology is leading to. When you study soil technology, what we are trying to do is we are trying to go much more into the intricacies of the interaction between different phases of the system and it is always futuristic. That means what you have been doing, what you know till date, you are going to add on to the present day knowledge. Let us see further shrinkage. People have already studied a lot this phenomena. We will try to revisit shrinkage and the mechanisms, swelling and cracking characteristics of soil. These are the issues which require a lot of attention of geotechnical engineers and civil engineers. Hydraulic conductivity and mass transport phenomena. Another way of saying mass transport, contaminant transport is basically mass transport. Hydraulic conductivity is simple passage of water through the soil mass and mass transport phenomena would be when we talk about contaminants passing through it, heat passing through it, electrical current passing through it and so on. Now, incidentally if you know these properties, you may develop new models to understand the behavior of the soil mass or the rocks. Thermal and electrical properties of the soils. Where would you require thermal properties of the soils to be incorporated in the model? Can you give any idea why it is so important? Any other simplest possible situation which you may come across every day? See what is the difference in designing the foundation for a simple residential building and the buildings which are going to have some industrial units. And to complicate the problem further, if I say that this industry happens to be a forging unit or where the furnaces are there, what would be the difference in the foundation of a residential building and the buildings which are going to house these type of facilities? See, power supply cables that might be in the soil, they might be buried in the soil. So, whenever there is current passing properties. That is one of the examples. That is right. Yes. So, because of this thermal cracking may take place. Any other examples, the question which I was asking you. So, if you have forges or if you have furnaces for which you are going to or let us say underground storage of nuclear waste, radioactive waste or let us say hazardous waste at elevated temperature and so on. What should be the difference in the foundation and the type of properties of soils which are required? Now, this is where the thermal effects are going to come on the system. Please understand one thing. Till now, you have studied only the response of mechanical loading on the soil mass. You have never bothered about the loading in the form of excessive heat, thermal gradients. How soil is going to behave? Clear? And so on. So, this is where actually in this type of problem as she says rightly, buried pipelines, cables, conduits, refrigeration system, forges, hammers, ovens, furnaces, you know designing these foundations plus in nuclear waste, hazardous waste, the waste which are at very high or elevated temperatures. You have to understand the interaction between heat and geomaterial and contaminant. This is what you have been asking. It is a good example of how environmental conditions will augment or change the interaction properties between different attributes. Electrical properties as some of you answered, yes. I think you are quite close that electrical properties because of surface charges, passing of current, earthing of electrical utilities. This is where actually you are required to study electrical properties. These are some new concepts which we are talking about. Apart from all this, do you get some idea or hints where these properties can be used? Well, I will answer this question. These properties are being used for modeling purpose. Just to give you an example, if you are talking about soil-water air interaction and if you are going to do your conventional hydraulic conductivity test, where you are saturating sample or the water is seeping through the soil mass, what happens to this air component? There is no air component. That means, truly speaking, by doing conventional test, you cannot capture the response of a system in three phase, clear? And this is where you have to use some external amount of energy or external type of energy to model how hydraulic conductivity phenomena can be studied, can be understood and so on. Now, this is where actually if you pass current through the soil mass, you must have done in your undergraduate some experiments. You have the teledestrous paper, you cut out the sheet pile or a drain and then by using copper sulfate solution, you can pass the current through this teledestrous paper and you can draw the flow lines and equipotential lines. I hope you must have done this experiment. This is one of the ways how electrical analogy can be used to define the porous media properties, clear? In a slightly complicated way, if I know the electrical properties and thermal properties of the soil mass, I can model its property and its behavior in a better way. Keeping all these three phases intact. Now, did you ask a question to yourself ever when you were doing hydraulic conductivity test? By mistake, if you leave the samples, let us say for few months in the permeometer, what is going to happen? Why you should do this test only for 72 hours? There is no interaction in nature which is limited to only 72 hours. You agree? Then why should I simulate a condition for 72 hours interaction only in the laboratory? So, these are the typical questions actually which are coming in the minds of the researchers. You agree? So, how to get the answers? Because no interaction is limited to 72 hours or 24 days or whatever or 28 days of curing of concrete and all. Once the structure is existing in the environment, it is going to be there forever, at least for 25 years, 50 years. And in a climate like Bombay, what you did not like about IIT Bombay? The first site, you go to IIT Kanpur, IIT Delhi or some other place, you may like to see something which you are not finding in IIT Bombay, the quality of the building. Why? The environment is so aggressive here. Why it is so aggressive? See sure, what is in the air? Humidity. Humidity carries what? Not sulphur, chlorides. And these chlorides keep on penetrating into the concrete. What happens? The average life of building here is hardly 7 years, 10 years, 12 years at the most. This is what is known as chloride impregnation in concrete on which lot of research is being done. So, these are modeling tools. These are the philosophies by which you can understand how a system is behaving. And of course, the radiation effects on soil, India is becoming a superpower in terms of atomic energy. But believe me, we do not have people who can handle the issues which are being asked a question by the atomic energy. Why? Our civil engineers are not trained for dealing with challenges associated with radiation effects on soils. So, this is the need of the hour where you should have all these things when the entire course cannot be limited to only this. But of course, these are the few major, I would say, topics or subtopics which have to be included in this type of a scenario, existing scenario. Anything else which you would like to add here? Having studied all this, you were talking about gen, the application part. So, the whole idea is you study everything, but then ultimately you have to apply it somewhere. So, whatever research or whatever concepts you are revisiting or you are evolving, they have to be applied in some form. So, what are the applications of these concepts? Unfortunately, the course may not be in a very systematic or an organized manner. You may find it. But on and off, I will be giving you examples which are related to these topics. And again, as I said that this subject is in a very nascent stage. Frankly speaking, even I do not know many things myself and I am trying to get the answers from my students like Prima, Pashit and Kunal who are working on different problems and giving me answers and educating me every day. But of course, it is a learning procedure. The process goes on and on.


Let me show you something cool So what just happened here? This power supply created a current a flow of electrons traveled over here to a capacitor Now a capacitor is two metal plates in an insulating oil Charge can't flow through the oil from one plate to another So it builds up on one of the plates charging it negatively the other plate is left with a positive charge This creates a potential difference some voltage across the capacitor Potential difference is kind of like potential energy the more charge you build up between the plates The more voltage you have and the more energy you have stored in the capacitor I've been charging this capacitor for about 20 minutes, and it's charged up now to about 3000 volts from this potential difference. You can calculate that there's 450 joules of energy in this capacitor So that energy just sits there until I flip this switch When I do that I'm completing a circuit where an iron wire connects the two plates of the capacitor Imagine just drawing the Hoover dam Huge water flow. It's the same thing here electrons will rush from the negative plate through the iron wire to the positive plate and the wire can't handle all that current Now the voltage in the capacitor after it's been charged up is going to be really high That means there's a lot of energy that's going to flow through the iron wire Because the wire has some resistance and is very thin it can't handle all this energy as the current flows through it Some energy dissipates out as heat, but there's just so much heat that the wire explodes Now the wire actually explodes before all the charge can finish leaving the capacitor So I'm going to take this copper bar and touch it to the two capacitor plates so it can finish discharging Now the thick copper bar has a much bigger cross-sectional area than the thin iron wire and has less resistance So it dissipated the energy better and didn't explode
