I'm the manager of the infrastructure team with SafeWork New South Wales. We have an overall silica strategy but I guess it's important today for you to recognise that most of what I'm going to be covering while I will cover the overarching strategy is about what we in the construction and asbestos services team are doing with particularly the infrastructure and construction industry sectors. Our work health and safety roadmap was developed after we became SafeWork New South Wales. We split from the old work cover New South Wales into three sectors which was the workers compensation, the workers compensation regulator and obviously SafeWork which is the work health and safety regulator. Focus on really declining fatalities and serious injuries and particularly I think we're ever increasing focus on illness which I think is a really important focus that we probably haven't had as much to do with over a good 10-year history so it's really good to see that we are having a better focus in that space. We've got some clear action areas and I guess the one that really falls into this is about those high-risk calm in terms of those injuries and illnesses and it's also about us being an exemplar regulator so for us part of the work that we've been doing with the industry sector is really about getting buying from everyone across the industry and making sure that what we're doing is actually providing some benefit but also that we're able to bring industry along with us. So why are we focusing on silica? As part of the coming together of SafeWork there was a lot of analysis done on the data and international and national research. From that SafeWork came up with two specific chemicals that they were going to focus on and one of them happened to be silica. So we've put that in our health and safety in terms of controlling that exposure and that's across the board not only in the construction sector but across the board but I'm going to be talking about what we're going to do in the construction sector and obviously some of the biggest reasons why we're doing that is the amount of tunneling that is going on across the state but also the amount of work in sandstone and rock that's happening not only in tunneling but also in residential and excavation work that's happening across the state. So this is just an understanding of our hazardous chemicals and materials exposure strategy at focus around a number of different types of activities that we're doing which is both doing that site type activity inspections, getting out their workplace visits, creating that awareness around illnesses and particularly in relation to silica which I still think people don't have a great awareness of the effects and what those long term health effects are and we're also doing a lot of research so we've also had a work health and safety centre of excellence initiated. We've got a number of data researchers who are working at both the international and national level in terms of improving our data in that space. So what is it that we really want to achieve through this program? Firstly I think awareness is one of the big factors and still that lack of awareness is a real issue. We have the biggest construction boom that's ever happened in this state. We have workers working in these types of environments who have never been in that type of environment before and while we have some experienced people who have been, we've also got this whole range and a new group of people who are coming in who just don't have that awareness so that's a big part of what we're trying to do. It's also for us to understand and I think as an organisation for us we never had a full understanding of what was actually happening underground and probably as an organisation historically we haven't really had a lot to do with it apart from some of the major tunnel collapses and things that have happened in the past we haven't on an ongoing nature actually been down in the tunnels. So for us that was a big part of it, developing our own people in terms of understanding what's going on. To work collaboratively with industry and that's obviously a big part if we don't get industries buying into the things that we're doing we've already lost the caper. We have a lot of specialised and highly skillful people across the industry sectors who we need to work with and we need to get on board in terms of making this change that will be long term and hopefully will be of benefit to the future generations. We've conducted a number of site visits within the tunnels and that's every major tunneling project in the metropolitan region and been doing assessments, hygiene assessments, we've been actually looking at the data and we've been looking at the work practices that are happening across those tunneling contractors and really been gathering that information on what is good practice, what do we expect that we should see down there and what are some of the challenges or what are some of the areas where we think we can actually improve and make a difference in terms of reducing that silica exposure. Again continuing in collaborative discussions and I think we've initiated an air quality monitoring group which I'll talk about a little bit later but I think that's been a really successful way to get all the major players together and actually just start these discussions about where we're at and where as an industry do we want to get to. And I think certainly from my point of view it's been a really successful group to get together and actually shows what people can do where they have the will to actually get together and start talking about some of these things. I guess it's always important to when we are going about these things it's important to look at the good things that are happening and certainly in this industry sector as opposed to a number of other different sectors there are a lot of positive things happening in the silica space and I think as an industry sector it's an opportunity for them to actually influence and provide positive futures for other industry sectors where we can start making changes after the ones we've made in this industry. So without going through all of them some of the ventilation that we've seen is really good when it's put in place properly and it's really effective in terms of what you're trying to achieve. We have had use and it's consistent and inconsistent at times of misting systems the use of rattles and curtains blocking off areas of the workspace and setting up the proper ventilation to get rid of these dusts. Issues that prevent people having to get out of cabins. There was a lot of problems. You have positive pressure cabins which is fantastic but if you open in a door it takes away from the engineering control that you put in place. So in terms of that it's been really good and there's certainly been some good compliance rates in certain areas down in the tunnels. So there has been some really positive things that have occurred but along with that there's obviously also some challenges and some of the challenges that we're trying to work through at the moment with the different joint ventures is really what does that good practice looks like. For us as a regulator we've been going down and doing visits to all these tunnels and the practices across the tunnels are sometimes quite different. So the challenge for us and I think for the contractors themselves is to say firstly why are they different and if they are different are they providing the same level of safety that we would expect. So there's some of the things that we're really going to be working on over the next couple of months in terms of trying to achieve a better consistency and in particular that reducing the concentrations of silica just it is a challenge and there are areas where it's just sometimes very difficult to achieve but then there are other controls that you have to put in place if that is the case. The level of awareness we sort of talked about and I think across the board in this sort of environment there's always been a really heavy reliance on PPE and I think wherever we can look at options in terms of those engineering controls and how we can actually control these things at the source that's always going to be a much more positive benefit if we get to that space rather than the lower order controls. So one of the things we're really proud of is the Air Quality Working Group I think that's been a really significant achievement in terms of getting a group of people who are often opposed in terms of the types of contracts that they have together to actually come together and start talking which I think has actually been a major achievement and that committee is really about trying to say, you know, what are we about? This is not about getting anyone's technological advances or having an improvement in contract relationships this is all about sharing information on the health and safety and how we reduce the exposure to this type of dust and I think, you know, it was a hard to start with but now we're actually there I think it's really showing some good results. It's also about sharing the results of de-identified silica monitoring the mines do it really well, they have a really mature dust committee that are very mature in the way that they share information and I think if we could get to that space it would be a really positive environment and place to be in. It's about sharing what good practices are and in terms of those inconsistencies, you know, is this one better than this one or is this one better than this one and why is that, you know, is it going to create extra costs or resource issues or actually is that just the one that we all should be using so I think those conversations can all be beneficial and also obviously getting feedback on the challenges that are faced by everyone and one of the things that we see constantly is that the challenges remain the same across the tunnels and you're all facing the same challenges so if you can come together and deal with it on a conglomerate basis it's always going to be beneficial and also as a consultation mechanism for that guidance material I want to develop some what does actually best practice look like in this field so we've currently had three meetings we've got two subcommittees that have been initiated one is looking at health monitoring and I think, you know, for all of us in the room it's pretty clear that there's some real gaps in terms of the way different people are doing health monitoring and in particular in terms of the way that people move across different work sites how that health monitoring is affected is a real issue that we're actually trying to tackle and again come up with a consistent kind of approach to what that should look like there's also some work being done on this training package which is really around, you know, what does a good induction look like you know, where should our people be in terms of that education space before they get into a tunnel or one of these workplaces we've done some joint visits with hygienists as I mentioned before and that's across all the tunnels to have a look at the results and to just see what's going on down there and we've also done a couple of visits to the mine rescue facility and it's interesting to see the different approaches from the mine sector to the tunneling sector and obviously there are differences in terms of the types of environment that are down there but there's a lot of similarities as well so I think that's been a good thing for us just to finish off I'd like to say that it's been really great working with the industry we've now got a number of meetings with all the joint venture partners where we're actually going to discuss what we can do now in terms of some changes and how we can reduce that silica exposure with really basic things that can happen right now and then what are we going to do in terms of being able to work with you in some of these more complex areas of exposures where we haven't quite got to what best practice or even what compliance might look like for instance so particularly some of the back end works that are starting to happen benching, you know, even some of the above ground works I think we're quite there yet so looking forward to the next couple of months and being able to get to a place where we're being able to deliver a bit more in terms of what compliance looks like so thank you


Sister. Sister. No. Oh, okay. What happens when friends become as close to you as sisters? Keep watching to find out what book we're talking about today. I'm Kyla Denignio and Merry Christmas Eve. Happy Christmas Eve. This is another video for Vlogmas 2022 and I am covering book reviews every single day for 12 days, okay? So today we're talking about the book Sister, Sister. This book was written by Eric Drumdicky. The genre of the book is fiction. The theme of the book is African American literature. So this book is really important to me because this is one of the first books that Eric Drumdicky wrote. So let me give you a little bit of background because I'm a big fan girl for him. So Eric Drumdicky actually was an engineer for a number of years. Originally from Memphis, he moves to California. He works as an engineer and his friend asked him to go to a creative writing course. He went to the course and fell in love with writing and then the rest is history, right? And I learned that from one of the interviews that he gave because I always read the author's notes in the back of the books. I watch any interviews that I could find with him, listen to them as well because he's really one of my favorite authors, okay? So one of the most important things in this book is when Black meets Chiquita. There is drama, there's cheating, there's love letters, there's brick, crazy stuff that happens, right? And it's really funny because as you're reading the book, you find out later that Chiquita actually is from Memphis and she ends up going back home to meet up with some family but you actually see that Eric Drumdicky constantly mentions Memphis or Tennessee in his books. He really has that strong tie to Memphis and he makes sure that he leaves those little treats and books for the reader to find. So Black and Chiquita, who are these people, right? This is really important because these are two sisters who aren't related but become really close friends and then you have Black and Red and they actually are blood sisters, don't look anything alike and then this actually could be called complicated families because the book also includes Brown who is the brother of Black and Red, right? Black, Red, Brown. All of them together make up a family but then you actually get to see how Chiquita comes in and she becomes a really close, a really tight part of the family as well, okay? So the way that Chiquita meets Black is really important because everything from there is a snowball. I mean snowball. It does not stop, it does not slow down at all. The pace of the book is very, very fast and I love to watch Red and her relationship with her husband Black as she's starting to date and Chiquita in her issues and finding out is blood thicker than water, okay?  If you're not blood relatives, it's just water. So would I reread the book Sister, Sister? Absolutely yes, okay? One of the strongest reasons why I would reread it is because Airdrum Dickies books are time capsules, okay? Sister, Sister was published in 1996. You want to hear people talking about C phones, pagers, calling answering machines. This book captures all of the jargon, all of the technology, all of the stuff that people were doing in 1996. I sound like a historian but yeah, with this being one of the first books that he wrote, it really is important to go back and read even out of order as I'm going through Vlogmas because you need to see the current books that came out within the last couple years and then books that he was writing back at the beginning of his writing career, okay? So thank you for hanging out with me for Vlogmas 2022. This was video 11 as a part of a 12-day series that I'm doing one book review every day for 12 days leading up until Christmas, okay? So if you enjoyed this book, if you believe that blood is stronger than water, get in the comments, talk to me about it, talk to me about whether or not you've read this book or if this book even sounds interesting to you, okay? So I will see you tomorrow for another video of Vlogmas and thank you for watching. Bye.


Can you answer that now? I don't know the answer to that question. I don't know the answer to either of those questions I don't know how many you've had no whether there are any were any no personal knowledge of this matter I don't I don't I don't recollect the answer to that question. Hello and welcome back So I just got done watching the oversight hearings of AG Merrick Garland And all I can say is that I'm very worried for this country Merrick Garland is brazenly partisan and corrupt But he knows he has the media and we'll get away with it and it gets real bad During the heated questions from Republicans Merrick Garland seems to suggest that his Jewish religion Somehow puts him above scrutiny and shields him from criticism We're gonna analyze Garland's insane response to completely legitimate questions But first a quick capitalism break with noble gold Do you want to take control of your financial future, but just don't know where to start? Noble gold investments understands investing in precious metals may sound confusing But the team at noble gold investments make it easy right now Noble gold investments is offering a free five ounce silver America the beautiful bullion coin for qualified accounts So why wait let's get started right now go to noblegoldinvestments.com now That's noblegoldinvestments.com the only gold company I trust and remember there is always risk in investment And there are no guarantees of any kind The Justice Department was founded in the wake of the Civil War and in the midst of reconstruction with the first principle task of Bringing to justice white supremacists and others who terrorize black Americans to prevent them from exercising Their civil rights just imagine the actions they can justify taking in the name of their safety Government officials are accountable to the people and their elected representatives Garland and those agents are just servants of the public and Deserve every bit of criticism. They're getting that promise is also why I am here My family fled religious persecution in Eastern Europe at the start of the 20th century My grandmother was one of five children Born in what is now Belarus made it to the United States As did two of her siblings The other two did not Those two were killed in the Holocaust Notice how he sounds like he could be any Democrat politician or a pundit on CNN or MSNBC Notice how he couches his actions in the fight against white supremacy. He's doing this to justify himself to the woke He was half the country and maybe a little bit more to think that what he's done is okay because he's doing it to white Supremacists when you see your political opponents as literal Nazis then you can justify doing anything to destroy them And that is what leads to what you're about to see never in my life What I would thought that I would see such a politicized DOJ never in my life what I thought I would see such a Department of justice that didn't obey their own rules never in my life Did I think I would see the egregious investigations conducted on your you under your watch? Or the blatant disregard of the First Amendment by FBI field offices under your watch And never in my life did I think I would see our great DOJ Turned to an into a politicized weapon to be wielded by an investigation to attack Political rivals for that you must be held accountable I hold you accountable for the labeling of parents as domestic terrorists Standing up for the their proper education of their own children I hold you accountable for the anti-catholic memo Imagine sending agents undercover into Roman Catholic churches because they were supposedly domestic terrorists The actions of the DOJ are on you the decline of Americans trust in our federal law enforcement is on you The popped political weaponization of the DOJ is on you Attorney General I need a simple yes or no to the following just yes or no because we don't have much time Do you agree that traditional Catholics are violent extremists? Yes or no? Let me answer what you've said in that long list of Happy to answer all of those attorney general I control the time I'm gonna ask you to answer the questions I asked control time by asking me a substantial number of things And I didn't ask you those things. I will answer the attorney general through the chair I ask you do you agree that traditional Catholics are violent extremists? I have no idea what you're what the traditional means here Let me just go to church may I answer your question? Yes idea that someone with my family background Would discriminate against any religion is so outrageous.  Oh, no, sorry, I'm of Scottish heritage and my people were oppressed So I couldn't possibly be guilty of racism bigotry or xenophobia He's above scrutiny for a policy that happened under his leadership that targeted Catholics because he's Jewish Get the out. What does that even mean? Is he saying that a German person in his same position could legitimately be accused of these things? But somehow he's above him because he's Jewish as racist that he would try and slither away from Accountability for his partisan targeting of Democrats opponents by using his religion as a shield tells you all you need to know It's all good, of course and Garland actually gives it away. Yes, the idea that someone with my family background Would discriminate against any religion is so outrageous This is so absurd Mr. Attorney General, it was your FBI that did this it was your FBI that was sending and we have the memos We have the emails we're sending undercover agents into Catholic churches both I and the director Have said that we were appalled by that memo So then you agree that they're not extremist you were appalled by that memo. Are they extremists or not? Attorney General, I think that are they extremist or not attorney general in that memo Are they extremist or not? I'm asking a simple question say no if you think that was wrong. Flicks are not extremists.  Tell me yes or no, please. I don't have no time. I don't know the answer to that Now you see now This right here is how you know Garland is full of it first He says that he couldn't ever possibly be accused of discrimination and the very thought is outrageous to conceive But then one asked if the person who made this anti-Catholic document had been punished suddenly he has no idea or interest Does anyone think for a moment that if somebody within the FBI or DOJ put out a similar document about Jewish or Muslim people Not only would Merrick Garland know about it, but everybody on the planet would know about it And that person would be publicly punished Merrick Garland is a straight-up scumbag And there are lots of other gems that happen throughout this hearing which will go over during a live stream on Rumble tomorrow night Let me know in the comments what you all think about these hearings, and I'll see you all in the next one Thanks for watching


and not to security martyrs. The Niger army says 104 members of the Islamic State of Ostavikin province, Iswab, and their families have surrendered to the troops in Borno State. The army disclosed this on Monday via a verified Facebook page where it shared photos of some of the repentance terrorists and their relatives. According to the army, the former Iswab fighters surrendered their weapons on Saturday to troops of the 25 tax force brigade at Dambuartad of Borno State. A breakdown of the figure shows that 20 of those received by the soldiers are men, 27 of them are women, and the remaining 55 are children.


If you've invested in generating these data sets, why would you keep them to yourself? I think that data sharing and open data is really important for the whole scientific society. I think there is great value in collaboration. I think nobody wants to reinvent the wheel which is already there. We make our data accessible, we make our results accessible, we also make our technology accessible. It saves time to use the data that is publicly available. It saves money too. And there is such power in the data collaboration because that increases confidence in results. So the first step in this process is that we typically pre-print our papers on a website called BioArchive. It's a paper repository. This is completely open access and it's slightly nerve-wracking. You finalize your manuscript, you hit submit and within a few hours that is completely open to the public. This is quite a new concept. You sometimes get a lot of interest on Twitter, a lot of debate and discussion about your paper. So you get immediate feedback. So it can be nerve-wracking but it's also extremely satisfying as well. Knowing that you are making your work available immediately and there's not an 18 month delay before the public see the work. I think it's the worst thing if you develop something new and then nobody will use it because they can't access it. So for us it's really to give us a wider reach to enable people to use it. So that's why we release as much as we can when we publish. It's changed the field of cancer research because again with this kind of data availability all the computational modelers can access this data freely. They can easily get into this field and bring new models, bring new insights to this data. They can work together, collaborate with cancer biologists to get new insights to get better prediction capability. I think our main aim is to find cure for diseases. In my research I have shared within WashU my code and my data and I have also used people's data in the campus. If I can go ahead and download the data or use the data that has already been analyzed. The entire idea is that so that people can go ahead and save their time and gain knowledge from the data that is already being used. We developed this technology to apply to our questions on stem cell biology so a very specific area. But people are seeing the opportunity to apply this technology to cancer biology questions, developmental biology questions and this is giving us direct feedback because they're saying to us, hey it works in the system, this is what we're finding. Then other people are telling us we're finding this issue with the technology, it doesn't translate very well to this system and that's giving us ideas and inspiration for how we can tweak our technology so it works in a more broadly applicable way. And I also think that the future trend is to have more of this collaborative effort and make precision medicine a reality. Ultimately as scientists we should be trying to make an impact, we should be trying to move the process of discovery forward. Reproducing each other's result and hoping that we have cure for diseases like cancer. Then eventually I think we have better prediction models, better technologies to help our patients. So why wouldn't we share our findings? I would definitely like to see this whole process expanded of open source public data and I'm very happy that I'm working at this age of where this is actively evolving and I'm happy to do my part.


Hello friends, let us discuss the factors which affect the cardiac output. So let's start with this equation and see what are the factors affecting the cardiac output. So anything which increases heart rate and increases stroke volume will increase the cardiac output. Now this stroke volume is in turn dependent on two things. One is shortening of the muscle fibre. More the shortening of the muscle fibre that is more it is contracting it will cause increase in the stroke volume. And the second aspect is the size of the ventricle. More the size of the ventricle that means there is more muscle mass. So obviously its contraction will cause increase in the stroke volume. So now let us see what things will affect these aspects. So first thing we will see is two limbs of the autonomic nervous system. So first is sympathetic activity. Sympathetic activity increase in sympathetic activity leads to both increase in heart rate as well as causes increase in the stroke volume by causing increase in the shortening of the muscle fibre. On the other hand there is parasympathetic activity. Parasympathetic activity decreases the heart rate but has minimal effect on the stroke volume. This we should be very clear that parasympathetic activity basically supplies the SA node and it affects the heart rate and not stroke volume because there is minimal parasympathetic innovation on the muscle as such. Then next is the effect of the preload as we have told that there are mainly four factors which are important heart rate, stroke volume, preload and afterload. So preload also affects both heart rate as well as the stroke volume. So preload increases heart rate. This occurs by a phenomenon known as bain bridge reflex. This is basically that whenever there is increase in the preload certain nerve fibres in atrium are stimulated and via reflex mechanisms they increase the heart rate. Plus there is also some direct stretching of SA node which leads to increase in heart rate. Then this preload also increases the stroke volume by increasing the shortening of the muscle fibre. This happens because of Frank Starling law. Now Frank Starling law says that force of contraction is directly proportional to the initial length of the muscle fibre. So whenever preload increases what happens that it stretches the muscle fibre that is increases the initial length of the muscle fibre causing increase in the shortening of the muscle fibre. So see this preload is already incorporated into this equation. Now when we think about preload we should be very clear that there are multiple factors which affect preload itself. So preload is first of all affected by blood volume. So increase in the blood volume will increase the preload. Then there is a effect of gravity that means suppose we change our position from lying to standing then in that case the preload decreases. Then there is contraction of our skeletal muscles and abdominal muscles that also affect the preload. Then there is ventricular compliance that means how stiff or how compliant the ventricle is that means if it is very stiff so it will not relax and if it doesn't relax it will affect the feeling of the heart so that ventricular compliance is another factor. Then there is atrial contraction because atrial contraction causes the last push. It is responsible for approximately 10% of feeling of the ventricles. So atrial contraction will also affect the preload. Then another very important factor is venous compliance that means how much blood can veins accommodate. Now this depends on the diameter of the veins. So if veins have lesser diameter then that means they will push the blood towards the heart so that is venous compliance. Then push from the heart itself that is contraction of the heart that means we can say the cardiac output that also affects the preload. If heart is not contracting obviously the blood will not move. So this phenomena is known as vis atergo push from behind is vis atergo. So if there is a push from behind there is also a pull from front that is known as vis affronte. So there is another factor vis affronte which affects the preload. This is basically whenever there is increase in the size of the thoracic cavity as during inspiration. So it creates a negative pressure in the thoracic cavity and this creates a pull force for the blood. So this also affects the preload. Okay there is quite a overlap of the arrows but don't worry we will just in the end we will make a clearer flowchart for you to take it. Okay now what about afterload? Well afterload actually decreases stroke volume. So it actually decreases the shortening of the muscle fiber. So it is at this level that afterload acts and decreases the shortening of the muscle fiber. So see this is also incorporated in the equation itself because afterload is affecting the stroke volume. Now right now we have drawn just one on one arrows which are affecting these four factors preload, afterload, heart rate and stroke volume. But there is lot of crisscross also because the sympathetic activity affects the venous compliance as well. When there is increase in the sympathetic activity it causes venoconstriction and venoconstriction will in turn lead to increase in the preload. So sympathetic activity is affecting heart rate, stroke volume as well as the preload. Also it increases the afterload because sympathetic activity causes constriction of the arterioles which are responsible for peripheral resistance. So this sympathetic activity increases the afterload as well. Then there is something known as force frequency relationship that means increase in heart rate causes increase in the stroke volume. This is known as force frequency relationship or also known as Bowditch phenomena. So this happens because when heart rate is more it causes with each cardiac impulse there is increase in calcium inside the cardiac muscle and as you might be aware that calcium is important for contraction. So this increase in calcium leads to increase in the stroke volume. So guys these are the factors which affect the cardiac output. Let me just show you a summary of all these factors in a clearer project. So this is a clearer summary.

Now let us look at a study done by some students whom I supervised, so I will simply go to their presentation. So this team of students led by one Carlos, they took part in a global competition, ARWA student design competition for a hybrid ultra heavy like lift cargo vehicle. And they called this as Hulk VT because VT is still Virginia Tech. So you can see the idea is to come up with a vehicle for 2020 which can combine aircraft, airship and overcraft technologies. And look at the serious requirements or the large design requirements. You have to carry 1.2 million pounds of cargo over a distance of 6000 nautical miles around 12000 kilometers approximately nonstop and at a speed of 110 knots. So these students carried out a critical study of the design requirements and the ones which are in red color are the 3 design drivers that they established. And you can see that the amount of cargo to be carried is like something like 9 tanks or 6 Apache helicopters, they have to be taken nonstop and delivered. So they came up with this design and I will take you through the work that they did. This is a presentation which was made by them. So here is a picture which looks at the largest ship in the world and it compares the dimensions of the proposed airship with all the big aircraft, Hindenburg and the biggest ship. And this is the design cycle that was followed. They started with an envelope, did the structural analysis, did the overcraft work, performance estimation, stability, total weight and then I treat it till it was converged. So there are many types of cargo to be carried, not just one type, it is on the big list. So which combination of that cargo is going to give you the maximum space requirement you do not know in the beginning. So what they did is they did various types of combinations of the cargo to be carried and then they sized the envelope. This is a picture that they came up with for typically how their cargo given will look like. And this is the final configuration of the crew compartment or the place where the crew, this vehicle is going to fly for a very long time nonstop. So you cannot have just pilot and co-pilot, you will have to have people who can be rested and replaced. So there are 4 bunk beds, at any given time there will be 8 people operating this particular vehicle. Then they started by defining just a simple oblate spheroid shape with length, width and height and then they did some kind of a parametric study on the effect of the drag coefficient CDV, volumetric drag coefficient with respect to this L by W ratio and L by H ratio. So they found that as long as you stay within 3 L by W and within something like 4 or 5 L by H the drag does not increase rapidly. Similarly they located a panel code which was available in literature for axisymmetric bodies of revolution and then they did the validation of that particular code. So you can see the dots that you see red and blue dots are the numbers obtained by them against the data which they got from literature. And then again shape parameter versus the lift coefficient. So it remains pretty flat as far as the L by W is concerned but L by H length by width there is a marked effect especially when you go towards the large values. So with all these studies this is the final shape that was decided. So the bottom portion will have some contour and the top will have some contour. This is the cross sectional shape. And then again further studies they studied for various buoyancy levels what kind of CD is surface area and CD will be available. And the same kind of system which we saw compressed gas system, a similar system is being proposed here for reducing the volume. It is impossible for you to use conventional ballonet in this particular system because the ballonet will occupy such a large part of the envelope there will be hardly any space available. This is some work on the basic structural dynamic modeling of the configuration. So you can see there are these, the blue line for example is the buoyant lift along the length from 0 to 1. The blue line gives you the aerodynamic load distribution, sorry the buoyant load distribution and that will purely vary by the cross section because it is purely a function of the density. The red one is the aerodynamic lift which will be more at the more of the quarter chord. So you will have a similar kind of a peak. Then structural weight will also be distributed purely as per the cross sectional area except when you come to the central area where you have the, where you have the payload. But the structure of the vehicle itself will generally vary as per the cross sectional area. This is the gondola weight which suddenly increases. Then you have fuel weight, fuel is kept inside the tanks. Fuel is only at the rear and then the envelope weight variation. Then they got the bending moment diagram and the shear force diagrams. They did structure analysis of the basic framework. So look at the amount of work it is involved in doing all these calculations. And finally one student I remember was focusing only on the air cushion vehicle system. So he studied what kind of vehicle systems can be considered and he zeroed into the air cushion system. So then he started looking at the theory and design of air cushion craft and then he designed a system which would be able to take care of the loads and he did the cost estimation also, what it will cost to make it. Then engine selection was based on the data available for existing engines for large aircraft. So this particular graph shows the cruising altitude on the X axis versus the cruising speed and he has plotted various aircraft which are large cargo carriers and this is the point for Halkuiti which is near the sky cat and the cargo lifter. Of course as you are going towards the airships you will come to lower altitude and lower speeds. Then from the data available on the internet and from the engine manufacturer there were 4 possible engines which were shortlisted, they were studied in detail and then finally one of the engines was chosen. And then in aircraft design we do what is called as constant analysis where each of the design requirements are to be analyzed on a graph having wing loading on the X axis and power loading or thrust loading on the Y axis and these lines indicate the constraints. So the area below these lines is infeasible and the area on the left and the right of the line is infeasible, sorry the area on the right of the line is infeasible. So with that you find out the operational point. Similarly one group of students were focusing on the sizing of the fins and they actually did calculations for stability, calculations for the moment coming when there is a one engine run out and then came up with the exact dimensional requirements. The fins are not small, you can see the horizontal tail is 11,000 square feet. Then one group was focusing on basically the central rowdy control so that the movements are not beyond what the aircraft can handle and with that you got the central gravity range for the aircraft. And then finally we had a 3D drawing of the aircraft, weight breakdown. So you can see that around 30% of the weight is basically for the internal structure. This is 26%, fuel weight is around 30% and payload is 28%. So the amount of fuel you need to carry is roughly matching with the amount of payload that you are supposed to carry in this particular example. And other things are very small in size, gondola is only 7%, material of the envelope is just 3%. Then these are other airships which they plotted, mission analysis, how it will perform. You can notice it is 6000 nautical miles and then they did a very nice animation which I do not have it being on from the place where it is supposed to take off that is Fort Lewis in Washington. What route will it take to fly to Busan in Korea which is supposed to be the place where they will be delivering it. Then cost analysis is very important because the whole exercise was to be judged against what is the cost that you will incur per kilometer per kg for transporting cargo as compared to other means. So for that they looked at what is called as the Dapka 4 model from Rand Corporation and then I will not go into the details but there are you know large amount of terms explaining various cost component. Important point is that if you produce one airship, just one airship is produced then the entire R&D cost is going to be put on one airship but if you produce more of them then some part of the cost can be offset onto the airships sold. So you can notice here that operating cost can come down from 1.16 dollars per pound to 1 dollar per pound. This represents around 17% improvement by making a larger quantity and they compared the location of Hulk VT with respect to water based transport, rail, truck, air and space. So it is somewhat matching with air cargo and then this is just some comments students made at the end of the presentation about what they learned in this exercise because they worked with me on this for about a year along with their course on aircraft design. And then this was submitted to the competition.


As my friends will happily tell you one of my greatest irritations is when there's a situation where there's some miscommunication occurring and somebody says oh, we've had a communication breakdown because In reality, there is no such thing as a communication breakdown despite the fact that it's one of my favorite Led Zeppelin songs of all time Communication is not like a car engine. It does not break down. It's not something mechanical that has a breakdown like that We have miscommunications, but that's not a it's not something that can break down per se now again It's a there is a specific process though to communication in which we can have miscommunications and misunderstandings and and unintended consequences through misinterpretation and so forth, but but there's no such things communication breakdown So I want to take a look today though at the process of communication the process of communication not the engine of communication but the process of communication that takes place here and so to do that I want to take a look at the transactional model of communication So this is the most contemporary most recent model of communication that we utilize and really demonstrates the different elements of the Communication process quite quite well here. So so we start off with this cool guy, right? This cool guy and and he's just hanging out He sees though that his buddy over here is doing something equally cool and he thinks to himself He thinks to himself Wow, that's so cool. That's so cool. I should tell him about how cool it is, right? I should tell him how cool it is so He does he says cool beans dude, right? He lets him know that what he's doing He thinks what he's doing is cool, right? And so there we have the beginning of the communication process So this person is communicating something to another person, right? I could be to another person could be to a group of people could be to himself But but we have the the communication process starting here So the first couple elements that we can recognize in this process are the first communicator Which we call communicator a and then the other person is communicator b, right? We call that person communicator b and we call them a and b We used to call them sender and receiver about the truth is they're both sending and receiving at all times So so they're not really a sender and a receiver. They are both senders and receivers So it's easier just to call them communicator a and communicator b to differentiate between the two the two sides of the communication here So communicator a has something that he wants to communicate to communicator b, right? And and the and what that is them the content of what that person is trying to communicate We call the message the message is what that person is trying to communicate What is the message he's trying to communicate that you're doing something really cool over there So he's this cool being student. So the message there is that cool being student. It's what he's trying to to communicate there Now he also has to communicate this somehow, right? So we have the what of what's being communicated in the message But the how comes through what we call the channel or channels. There could be more than one channel So the channel could just be you know using your voice to say so it could be that he called this person on The phone and said that it could be that he texted him left a post at no you smoke signals. Whatever The however or or whatever ways that was communicated Either way or ways that was communicated is what we call the channel the method through which the message was sent So we have this person communicator a Sending something to communicator b. That's the message and they send it through the channel and so far so good, right? But we see that this is really only one way But what if the other person after hearing, you know, cool beans did they recognize that this person like what they're doing? So they want to respond in some fashion, right? So what we know in terms of the transactional models that communication does not just flow one way as is indicated here It actually flows in two different directions. So if this person wanted to say, you know after he hears cool beans Do do you want to say hey, thanks, dude, and he does a little dab, right? Give them a little dab and in addition of that then we see that this communication really is operating in two different directions Not just one, right? So we have the message which is the the cool beans, dude But then we also have what we call the feedback Right feedback could be verbal or nonverbal response from the other person or people or whatever But whatever way that's communicated in return is what we call feedback So again, it could be verbal communication such as the thanks, dude It could be the dab which would be nonverbal communication or some facial expression or whatever Any kind of communication could be feedback in return, right? So now we have this transactional process It's a back and forth and and it's happening simultaneously. All of this is happening all at once As this person is delivering their message, they're presumably getting feedback and so forth. So so now we have the first Five elements of the communication process here. There are going to be seven total But we have communicator A, communicator B, the message, the channel and feedback are the first five So we've got a good start here. We've got the transactional part of the process going on But let's say that while this is all happening That there's there could be some construction going on in the background or there could be noisy traffic Or they're trying to pay attention and not get hit by a car or whatever Or the somebody could be watching TV or their roommates watching TV or somebody's watching TV in the other room And all of this could be distracting could be interrupting this communication could be making it more difficult To send and receive these messages, right? This is what we would call Noise anything that interferes then with the sending or receiving of those that message or feedback or interferes with that communication Is what we call noise and those little squiggly lines there indicate that it's interrupting. It's interfering there Noise could be something that we hear and oftentimes is again if there's loud construction or loud traffic or something It could be interfering with the way that or how effectively we can actually hear what's going on and be able to listen effectively But noise could also be other environmental factors like if it's too hot or too cold in the room It's hard to pay attention, right? Or it could be internal things like you're hungry or you have a headache or you're just distracted It could be something psychological like just being distracted You're making your grocery list instead of really paying attention to what the other person is saying so noise comes in lots of different shapes and sizes and formats and So but and noise is anything that would interfere with the sending or receiving of that message or feedback anything that interferes with the Communication process there would be noise So now we've got that sixth element of noise The last one that we're gonna look at here is what we call context and you can see context just kind of wraps around everything It encircles and encapsulates every part of the communication process because what we know is that communication does not happen in a vacuum, right? It happens somewhere some time some place with someone and so there are a variety of different factors involved in the context It could be things like the environment You get as it noises at hot is it cold is it is it a library?  What's the environment in which the communication is taking place? What's the relationship between those two people? Are they best friends? Are they total strangers? Is it a parent and a child? Is it you know, somebody in a romantic relationship? So those types of things will affect what's being said and how it's being said I mean even just a difference between an acquaintance and your best friend You swap those people out and there's a totally different communication experience happening They're based on the context of that relationship. You also have the situation again. Just what's the you know Is this an emergency situation? Is this just a casual situation? Is it what's the what's the overall? situation that's in which this communication is taking place and then Culture is a big part of this as well. The culture really informs and and Influences every aspect of this communication and it's part of that context It just encapsulates everything and infuses everything with new meaning and new interpretation And so culture would also be an aspect of context to consider in this situation and in any situation so so there you have it those are the seven elements of the Transactional model of communication and really no matter what kind of communication you're engaged in whether it's interpersonal meaning You know you and one other person or if it's you know A public speaking situation where it's you and then a group of people on the other side or whether you are both people you're Communicator a and communicator b you're talking to yourself in that situation All seven of these elements are in place at all times and really are just variables then based on What makes up the context what makes up communicator b? What is the noise that's going on there? These are all variables, but any kind of communication really comes down to these seven elements as we see here in the transactional model of communication If you have questions about the this model of communication or anything else related to the process of communication please feel free to email me be happy to chat with you that way and and interact with you that way and You can be communicator a and I'll be communicator b And we'll we'll you know sort things out in that way So I hope this helps you better understand the communication process not the mechanism of communication that can't break down Right, but but it can lead to misunderstandings misinterpretations or ideally will lead to effective communication scenarios So I hope this has been informative and helpful for you in understanding the communication process


Colleagues, this presentation will take exactly seven minutes, no longer. Ter and Morsana is a collaboration between municipalities, universities, museums, heritage sites and citizens. Cities involved are, for instance, Liège, Aachen, Jülich, Hele, Tongre and Maastricht. All cities in the direct surroundings. And the University of Liège has the lead in this project. The goal is to do research and to explain the common history and the shared identity of some major cities of the Euridio-Muse Rhine. The Euridio-Muse Rhine is situated in the border area of the Netherlands, Belgium and Germany. And you are, at this moment, at the heart of it. In which three languages are spoken, being spoken, and a variety of dialects. Ter and Morsana will construct and write new storylines, make 3D scans of existing remains, that is, archaeological remains, churches and town halls. Ter and Morsana will reconstruct models by combining new storylines and freshly made 3D scans. It will compose films, exhibitions, make augmented and virtual reality products and also do research on ethics, user rights, techniques, sustainable storage and future use. The focus on this short presentation will be how will Ter and Morsana come to write new storylines? Ter and Morsana will focus on the connections, on the relationships and the interdependencies between cities. And we will use the historical 3D matrix model. Ter and Morsana will use a framework based on research and a network based on knowledge and personal involvement. This is a picture of the historical 3D matrix model which I've developed and which you are not able to read. But that's okay and I will explain. I call this a model because it is based on an approach, a way of thinking and is not a fill-in form. It's very simple but very effective. In this matrix three X's are present. The first X is geographically based. For instance, cities as Maastricht, Achillege and Tongra are summed up. The second X is chronologically based and divided into historical distinctive periods. The third X and the third dimension is theme-based. For instance, geomorphology, economy, politics, society or language. Each cell requires selected information and at the end of the line the interdependencies and conclusions are being summed up. By using this model it is important to let go of the usual conventions, use proven facts and figures only and let new insights emerge. The principle of the model are use not as much information as possible and today we are talking about data, big data and even more data. But now it is usable to use not as much information as possible but as little as possible. Be selective. Select your information on specificness and distinctiveness. Think about what is really distinctive and leave the rest of the information for the moment. And then focus and describe the interconnectivity, the relationships and the complementarity amongst places and themes in time and based on these distinctiveness. Using this approach try to describe firstly what are the distinctive features for Maastricht in for instance Roman times based on for instance trade. Start with a long list and then create a short list of what is really distinctive. Be selective. And what are those of Hele, Ache and Liège? The first result cell then will show the composed distinctive features of the Eurydio in Roman times on trade or any other aspect you chose. Secondly, now that we have the Roman result then describe what are the distinctive features in Maurevingian times, in Kerylingian times, in late medieval times etc. The second result cell will show the composed distinctive features of the whole Eurydio on trade, infrastructure etc. through time. And then thirdly the third result cell describes when all the cells are completed the shared history and the common identity of the Eurydio in its completeness based on the selective and distinctive elements. Using this model following aspects have to be stressed. Really focused on distinctiveness through time the specific historical identity of each city will appear. By reducing information the picture becomes clearer instead of blurred by an overdose of information. After reconstructing the reduced information and its conclusions and consequences should be checked and checked again especially with the omitted information. I would like to give one example. Several books have been written on the Roman city of Maastricht with its roads, graves, a sanctuary, a bridge, a thermal based in complex houses, fortifications, sculpture fragments and many many finds. But Maastricht was not a Roman city, it was a small Roman settlement with a special function. In fact Maastricht can best be described when approached using the historical 3D matrix model as a settlement with only one distinctive feature and that is the combination of a road and a bridge. And one specific function and it was that Maastricht served as a harbour or port for Tongere to the west and Ache and Heale to the east. Further information is unnecessary for this analysis and blurse of view. This concise role description helps us to investigate how the settlement functioned within the economical and transport network in the Eurigio and brings lots of research questions. I've tested this approach on for instance the 4th century late Roman Castellum of Maastricht and its functions, it helps us to understand. More examples are available but cannot be presented in the short presentation. I would like to mention on the Merovingian period, graves, saints and minting On early Christianity, Saint-Savage is of Tongere, Lambertus of Maastricht and the moving of the bishops seas between those cities. And on the industrialization of the Eurigio-Muse Rhine, the relationships between Liège, Ache Stolberg, Maastricht and Vervier. Dear colleagues, what's next? I hope I explained in short the way in which Taro-Mozana will bring new storylines which will be combined with new 3D scans, new 3D reconstructions and new 3D models. Taro-Mozana will newly describe the relationships between the archaeological remains and the historical sources, cities and settlements. What is necessary to achieve these expected results? Discipline and selection and above all distinctiveness. Reduction of information is not easy and always disputable. But we need discipline, we need a whip. Intense collaboration is needed with the surrounding areas and cities. We need their knowledge and their data. And an open mind is needed but also a warning and that is what we learned today. Every selection is a form of interpretation and a step away of our primary data. Dear colleagues, thank you for your attention.


Now here's where stuff gets weird and I told you there's always more to the story when I'm talking about this stuff So here's where it is. All right, so we're actually going to use reinforcement schedules to decrease Behavior, this is odd because like we said the definition of reinforcement is to maintain or increase a particular behavior All right, so what we're going to do now is we're going to use reinforcement to actually slow behavior down So we're going to be talking about reinforcing different rates of behavior Okay, so that's the key here so we can use reinforcement to decrease rates Reinforcement schedules will maintain behavior at a particular rate so you can change that schedule and you get a clear effect on behavior You're still reinforcing not punishing the person or anything like that It's just that you're saying that what used to take maybe I used to require 15 responses per week or something like that now I'm requiring four responses per week and anything more than that four is Going to be ignored and anything and anything less than that four is going to be ignored But I'm going to reduce that behavior from 15 down to down to four Again, it's not punishment. You are not trying to reduce a behavior so to speak You know, it's not that contingency sort of thing to reduce that it's talking about changing the rate of a behavior You still want the behavior to occur. You're just maintaining it at a different rate You're not trying to get it down to zero So it's like at one of these differential reinforcement of low rates of behavior So trl differential reinforcement of low rates of behavior So the question to you guys what what do we mean by differential? All right, so think about that for a second before you go you know pause and pause the video and think about that for a minute but what we're really getting at here is That we're going to respond differently. We're going to reinforce differently So differential meaning we're waiting for something particular to happen before we reinforce. That's all we really mean by differential so differential a drl Will we can focus on a limited responding situation? So we're going to say a given number of responses is allowed over a time period So for example, some people like to participate in class All right, so some people participate in class at higher rates than other people do so you can actually get maybe you've got somebody That participates too much so you can put them on a differential reinforcement schedule A drl a low rate our limited responding situations where you say, okay only two or three comments a day are going to be reinforced I'm not going to reinforce you if you do any more than two comments And so that's your dr. You're lowering that rate. We can also talk about spaced responding So you've got that limited responding. We can also pace somebody with this Responding does not occur for a given amount of time and after that period has passed the first response will be reinforced so again What we're thinking about here is that if you make a particular response, I'm not going to let you say anything again I'm not gonna reinforce you. I'm not gonna call on you or whatever until you know, 20 minutes has passed I'm gonna slow down that rate of respond a lot of kids get you know Really excited and they start going really fast and asking lots of questions and doing all these things You can start to slow that down using a drl spaced responding procedure But again, it's differential reinforcement. So what are you using as the reinforcer? Well, that's up to you You've got to figure out what's reinforcing behavior and what tools you can use like I said earlier the premium principle Is a good one that you can focus on here But the idea with this is that it's a it's a it's kind of a special type of schedule, right? So you're scheduling reinforcers after a certain number of behaviors This one's a bit odd dr. Zero DRO There's some argument in the field as to what this really is is these there's such thing as a dr. Zero and Yeah, I don't know okay Because this starts to violate that rule of contingency when we're thinking about reinforcement So supposedly reinforcement the definition of it that we've that we're using is a contingent application of a stimulus following a behavior Right application or removal following a behavior that requires that you do something But a dr. Zero says we're gonna reinforce you if the response does not happen during a given time So I like to think of this as a Reinforcing reinforcing Abstaining behavior So if you abstain from a response for X amount of time, then I will reinforce you for that Right, it's a very applicable sort of thing You can do this really really really well and it works really well with fading and all these other things right? But again if the unwanted behavior happens during the interval, you know, again, we're looking for a Behavior not to occur which is a bit odd it kind of then logically goes backwards here If the behavior does happen during the particular interval that DR0 interval that you're after then you actually reset the interval. Again, there's the logical problem that we talked about. So what, again, instead of thinking of this as DR0, you can also think of it as DRO instead of DR0 because really what you're doing is you're just reinforcing any other response in a sense. So you're reinforcing other responses other than something other than the one that you don't want. So you're just making sure that one particular thing doesn't happen. It's a bit of an odd thing. And I just mentioned about fading and here's why. You want to go ahead and start with a very simple success thing here. So the idea is make it easy for them. So if you've got a kid that's talking out of turn, basically tell them that, okay, you need to remain silent for the next two minutes and then you're going to reinforce her. And then the next time it's four minutes and then it's eight minutes and so on and so forth. And you can fade that procedure up to an entire classroom setting. So you're going to change that duration but you start small to give those early successes and you can start getting reinforcers. And then once you get reinforcers, behavior starts to maintain and you can put additional differential requirements on that. This one's useful, differential reinforcement of incompatible responding, so DRI. So the response being reinforced must prevent the undesirable response from occurring. So think about what is incompatible with smoking a cigarette. So if we're wanting to set somebody up on a DRI schedule, what's incompatible with smoking this cigarette? Let's see, is walking incompatible with smoking? No, probably not. Is talking incompatible? No, probably not. Is studying in a library incompatible? Probably most libraries, you can't smoke in them, so maybe that one works. So you're going to reinforce other behaviors, behaviors that are not the smoking, but they have to be incompatible with it. I think the example I've got up here is swimming.  So it's an incompatible response. In the classroom, my teacher used to do this one all the time with me. Either I had to sit on my hands because my hands were always messing with my neighbors and flicking my pens and doing all weird stuff.  So the other thing that she would have me do, I'm taking back one of my teachers here, was the four on the floor thing and I'd be leaning back in your chair and all that stuff. So I know I'd always fall over and disrupt the class. So the idea was four on the floor. With all four feet of the chair on the floor, there's no way for you to be leaning back in the chair. So it's incompatible. Sitting in standing, smoking and swimming, all sorts of good examples there. So differential reinforcement of incompatible behavior, when you've got a behavior happening either in yourself or with a kiddo that you do not want, find a behavior to replace it with. So find a behavior that, and that's what we're trying to do is we're going to reinforce another behavior. So smoking is automatically reinforced by the nicotine. So we're going to try and reinforce something else here and reinforce it at a rate that will eventually replace that smoke. I mean, it's a challenge. This is pretty cool stuff for the classroom. It's a little harder to use DRI outside of the classroom at a lot of times, but it's definitely a useful procedure. Differential reinforcement of alternative behavior. So our alternative responding. So we're going to reinforce anything other than something. So it's similar to DRI, but the response doesn't have to be incompatible. It just has to be different. So as you saw in the background, I'm going to reinforce you for drinking the water rather than for drinking the beer. They're not completely incompatible. We kind of do both at the same time, but you know, two glasses supposedly, but the idea is we're going to reinforce the something else, something other than the inappropriate response or something, an alternative to the inappropriate responses. So DRA, DRI are some of the most useful procedures you're going to run into in behavior analysis. They're unbelievably used in an unbelievable frequency because they're very effective. We use them in combination with other procedures such as extinction and punishment and timeouts and all that stuff. And we'll talk about how to kind of integrate all these, but the basics here are just that you're going to reinforce something else. You're going to reinforce something incompatible or you're going to reinforce abstaining, right? So those are kind of those three approaches that we're going to take. And then we're going to apply those at further level as we start to add other techniques. All right, see you soon.


My what in the hell, my two? Pretty lit, man Why does it make me want to do the Irish tap dance? I just learned that right now in this very moment What is up you guys? Realistic Gaming here, and today we are in arts and crafts Backroom.exe as you can see we got a giant arts and crafts taking over our screener. Let's go to school. Shall we? Oh, hi Oh, Baldi? Welcome to my school house. Oh, it's moved by a towel. Oh Okay, so we just no clipped into the back Although there it is the the sock The demonic evil sock All right, it has begun. I think Okay, this is weird you walk and look with the WASD. It's so weird. I never played a game like this Okay, it says uh he has more notebooks than you if you had no books give them to him. Oh, that's not good. Oh No, oh, okay, we're dead. Oh My god, it's like Slenderman. We just got consumed by a frickin sock monster. All right, let's give it another go Welcome to my school house. Yeah, should have Baldi Just no clip already come on to notebook. Oh Wait he actually no clip different this time does the time you just like He flipped this time around okay, so Here goes nothing. I see 13 at the bottom of the screen. I think we have to collect 13 Everyone gets the tension. I quit. Oh wait. I see a click mark Okay, this bar is filling up Look, oh, okay, so we have to delete everything on the chalkboards that we come across all right So instead of notebooks we delete everything on the on the chalkboard from what it seems like Okay, and we are trapped in the back rooms. Is that it? Is that I see one down here my god Okay, so each chalkboard has something written on chalkboard and that is Baldi. Oh my god. He's raging. Why is Baldi always raging? I mean he only rages Okay, it didn't go away The first one we raced we raced what was written. Okay, apparently on that check on that chalkboard It doesn't erase whatever is written on it and now let's go have a look around over here. Wait. I see. Oh Shrek Dude, what the heck is going on here I don't think we were meant to see this at all because oh my god. He's doing splits I'm gonna shrink to split throw. He's a big fella Okay, this one's empty. What okay? We have ten more to go. All right, uh, I'll leave you two to your business Whatever the heck it is that you guys are doing. I Don't think we were meant to see that guys, but whatever. Let's keep on moving Let's just pour some bleach in our eyes and I pretend like it didn't happen. Oh gee healthy But I hear like static. I wonder if that's a arts and crafts Wait that that's a picture of arts and crafts This is restroom Okay, this is strange. Oh Another door is closed. Wait, we're trapped in here No, we're trapped. Okay. No, we're not. Oh my god. I was gonna start a panic, bro I'm gonna have a panic attack. Oh Oh, that's a close one All right, let's go back this way because it did come from over here, okay Baldi says you can't hide from me. Ha ha ha That that actually sounds like something that he would arts and crafts would say himself Okay, we need eight more. Oh Okay, we found another one nice math equals math math equals more math math math math math math math. Yeah, that's right math isn't fun, bro like Once you do you solve a problem and you think you're done you got to keep solving it. It's like infinite. Oh, okay Wait what play time? This has to be the exit, right? Okay, I think this is the exit once we get all the chalkboards Once we hit up all the chalkboards.  Baldi says you can't hide from okay We did this one bruh my god about to do the same one again. Okay, this program is a cancer Okay We need six more Come on. Oh This went on the floor Wonder what it says an apple a day. I Can't read it. So you can't look down an apple a day saves lives. I mean that is what that is true guys Eat your fruits. Oh No, he's right there. Okay. No, let's turn around. I Have to go that way because they have not been on this side of the map Okay, there's an wait Is this the empty one from the start? This is the star right bro. I really did that one. Oh No Please don't please don't We got a hide in the corner Okay, nice Oh my god, I thought we were gone is there. Oh What happened here? There's actually chairs in this one cool And then there's a tree And the apple fell I Guess that was them that goes back to an apple a day saves lives.
