guys it is uh sunday afternoon and we are gonna go out in a little bit and go meet the kids for something different i don't know you know we're just gonna try things one of the kids brian the adopted son has always wanted to go to um he's very food oriented and he's always wanted to stop at a particular truck stop on i5 and aurora oregon that has both subway sandwiches and cinnabon i don't know why so guess what we're doing today driving down to aurora to go to subway sandwich and cinnabon i don't know anyway i've been upstairs in the art room doing some cleaning i need to put some clothes in the dryer i think did a little bit of rearranging so that my crochet patterns i'm not actively using are here an easy to reference to pull out what i need they're not clogging up and weighing down my bag i did reorganize the bag a little bit dug out some i have this thing for jingly charms on most of my bags and so yeah and moved to some stuff that didn't need to be in here into the other room there's a few more things over here that don't really need to be over here or they could go somewhere else i don't know if i'm gonna deal with them right now but yeah i did also sweep the floor because i kind of made a mess yesterday so yeah we've also been updating our christmas shopping list because the kids um we're doing name exchanges uh secret santa that's it so we don't have to buy gifts for everybody you just have to buy gifts for your name and so um that means that we all have to put gift lists together which bob and i are doing uh today before we go have subway instant upon i don't know if we're gonna go anywhere else i don't know if i can talk mister into going to anywhere else we'll see we're gonna take the truck though so that ought to be a fun ride i don't think it's too far away so i don't think there's any need to bring my bag unfortunately but yeah quite sunday but there's nothing wrong with that i'll be back how does that look um i'm gonna try to talk mister into stopping by a walmart on the way home i not only want to check out some different walmarts and see what their yarn and craft selection is like ours seems to be lacking all the time and they may all like be that way right now um but i don't know and um more importantly i'd like to add a pumpkin to my collection so there's that i have a collection of outdoor pumpkins we did break one last year and i do love pumpkins and so yeah we'll see i'll be back hey guys it is monday october 23rd 4 30 p.m i know right i have been up here in the corner all day today other than doing a couple of quick chores working on mr bob's sweater and um altering the pattern to fit him i really wanted the sweater to fit well so i've only gotten one sleeve done but i only have one more to go i was hoping to get the sweater done today but i didn't really think i would because i knew the first sleeve would kind of be a challenge um for he has long arms and then the way they wanted me to do the cuff um was just not tight enough on his wrist so i took had to frog that a couple of times anyway i got it to fit him finally yay i need to make a couple of notes and um take a break do do a couple other things like quite a huge list of stuff i've got to get done this week uh art and youtube stuff so you know besides i want to get this done for him so yeah all right i'm going to make some notes set this aside for the moment um and um get my bag ready i think if i do any more crocheting tonight i think it'll probably be the granny square afghan um maybe i don't know on my keyboard i don't know um but i'm going to turn the computer on i try to get a couple quick things done there before mr gets off at work um and yeah anyway it's just it's been a quiet day and i've been able to crochet all day and i love it and i forgot one of the reasons i prefer crochet over knitting yes i can do both um knitting i have to think more about and knitting makes my hands hurt crochet i've literally been here in the chair all day i haven't probably taken as many breaks as i need to and my hands feel fine so yeah i do have compression gloves in case i need them so and i will now that i'm done i will do some you know finger exercises so all right that's it for the minute i'll be back i got two of the scheduled posts for november done after i finished the one sleeve on the sweater i got my november daily drawing and journaling journal done it's all ready to go it's all prepped it's just drying i have to film the arty trio video and edit it and then edit the vlog tomorrow also having some work done on a leaky window that's under warranty tomorrow so will i actually get the filming for the arty trio video film tomorrow i don't know i'm not babysitting so we'll see and the old arty trio video journal she's done she's empty i can't put any more in here i just realized i did the last page last month so gotta get a new one out anyway we'll see how tomorrow goes it's time for dinner and i think we have to move some furniture out of the way for tomorrow morning when the window people come to fix the window all right i'll be back but it is tuesday october 24th uh pretty sure yes at 9 46 a.m if the gentleman is here from the window manufacturer to clean and reseal the window um because we had a problem with it leaking and it's covered under lifetime warranty and um so that's being done right now i'm just relaxing here at the moment and i got a cup of coffee sitting next to me i'm gonna work on bob's sweater today and edit the vlog those two things have to be done today um we'll see what else i get up to i do have an arty trio video to film so there's that sometime this week ish sooner rather than later probably anyway uh yeah i need more coffee can you tell all right i'll be back so i let the daughter know that the window people were here fixing um what they needed to fix and gone done and gone already and uh she's still going to keep doing your home because they have a baby play date with some of her friends and their kids and he has swimming lessons he's already taking swimming lessons he's doing very well um but she might need help tomorrow so that works for me i told her just let me know because if not i will like run errands and stuff tomorrow um i am going to since i've confirmed that i'm not having him today i'm going to go ahead and film arty trio today and try to get that edited and the vlog edited and that way that's done one and done and then the only other thing i have to work on for the rest of the week is bob's sweater and getting his sweater done so that sounds like a plan to me all right i'm gonna put a few things back because we had to move stuff out of the way for the window guy because that transom window was leaking that's what they were fixing it wasn't sealed properly at the factory so they sent a um workman out to reseal it and so hopefully that's fixed no more problem it does have a lifetime warranty so if it's not well yeah anyway all right that's it for the minute i'll be back table by myself so i got a way for mr bob to be done with this meetings and be able to take a break so anyway and meanwhile i guess it's been a while since i initially initialized erased properly my sd card for my video camera so that's doing i also got tired of moving my tripod out of the painting corner and realized i got two more tripods in the closet that i picked up at the goodwill so now we have a table tripod and a painting tripod this one cost me like 12 bucks so if you're all wanting to film a video you need a tripod for something maybe just doing plain air and you want to set up an outdoor painting stand there's a million videos on that on youtube um thrift for a tripod don't go by one new anyway all right that's it for the minute i'll be back cards wear out who knew good thing i have another one great way to start the day okay it's about 3 30 ish i got the artsy trio video filmed it is now edited and saved and i got the vlog edited it's saving and i'll get everything scheduled before i turn the computer off today and i'm going to make myself a spider web thing for halloween a crocheted spider web thing and i had this old baroto knitting scarf kit i've had this so long these and these are the instructions for knitting because i do know how to knit it's not my favorite i think i'm going to split the yarn i'm never going to make the scarf so i'm going to split the yarn up and i don't know if i have enough but i'm going to take some black acrylic i have and i have this was in the kit and i'm going to put those together and make a sort of a sparkly spider web thing to wear and then this is also yarn in the kit this is baroco optic there's enough for a scarf here which i could make a scarf out of it but i think i might do something else to say what exactly i don't know yet but it's interesting yarn um so but that's not a today project um right now i am going to let the computer do its thing and i'm going to continue work on bob's sweater i started the other sleeve so that's a priority so anyway i'm just going to snuggle up in my corner in my chair under my blanket and crochet because why not all right i'll be there you guys it is wednesday morning october 25th pretty sure anyway um unexpected babysitting this morning because the daughter had a client she had to help with a property inspection and my daughter's in real estate for those that don't know i'll link her website down below if you're in the state of oregon and you need realty help she can do that if she's too far away from you uh for her and you to help you she can recommend somebody so anyway uh she did that this morning polys was working and so she's like mom can you babysit i said sure because you know um as you all know um if you follow me on other social media i got bob's sweater done last night i'll put a couple pictures up here turned out really cute the fits really well i took a little longer with it than i would have for a sweater for myself because i really haven't made one for him in a really long time and i wanted to make sure the fit was right so anyway it is all of 47 degrees outside and rainy yay i love that because i get to wear sleeves um we're gonna go run out and run our errands that we usually do Wednesday morning but we're gonna do now we're gonna run to the peel box check it it's been a couple of weeks i'm gonna go to value village because it's literally right there i need some more thrifted or scrap yarns for the scrap blanket i need variegated yarns so i'm going to and we're making this blanket out of scraps thrifted bits bits i'm gifted and inexpensive yarns if i have to buy anything it's an expensive yarn so we're gonna go to value village and see what they have if they have anything and then i probably will stop at walmart i'm kind of checking out all the walmarts near me to see who has sort of the better stocked yarn selection although i think they're all pretty much the same it just depends if you hit it when they've stocked the shelves well or not so yeah anyway we're going to go check it out this morning we have two walmarts near us but i'm going to go to the one near to the po box today bob is going out of town for work next week i don't have a problem with telling you all that because by the time you all see this he's going to be back but while he's gone i might drive over to the other one okay headed over to the last stop which is picking up a prescription um my walmart was pretty well stocked for yarn today um although the yarn department is constantly a mess and i guess i looked like i worked there which okay because somebody kept asking me questions i said i'm sorry i don't work here i did try to help her anyway that's probably why she thought i worked there so anyway um i'm planning another afghan so they did actually this time have the colors i wanted so i did buy them because it's cheaper to get it at walmart than anywhere else and now i have them i can just set it aside with the other crochet projects i have planned um blankets are good for me to work on when we're um on a road trip or you know i'm dealing with anxiety or you know i just need to keep myself busy then i stopped at joanne's they had i did find two balls to add to the thrifted and and gifted and scrap bits afghan i'm currently working on one was on clearance one was on sale they're both variegated um because i'm alternating variegated and solid i have four of them now i need to sit and look through them all anyway um kind of looking for a good crochet magazine so if you all have a particular one that you like if you crochet let me know because there used to be a lot more of them out there than there is but you know i think crocheting's not as popular as it used to be i don't know anyway we're going to go pick up their prescription then i got to go home and have lunch it's one o'clock and i'm starving so yeah i'll be back guys junior's here today i'm babysitting hopefully you can't hear that music in the background i'll try to drown it out if i can and uh anyway i am boiling some carrots for him because we're going to make some baby food and i have some leftover applesauce which i already made and he by the way he loves apples um i was up here for a bit before he came i know dark hello um and i decided to add a spider web to the back of my halloween shirt so spider web on the back spider web on the front spider necklace yeah i even have some plastic flies i'm thinking about gluing some flies on there i know it's really but you know yeah flies i have flies flies so anyway but we'll do that later i don't can't do it right now because junior's here so anyway all right i'll be back bob is still at his masonic lodge meeting um but while he's been gone i made great progress on the scrap yarn afghan we went through four balls of yarn that were in my bag four set afghan so yay um the balls that are left are all fairly large um i'm anticipating when the afghan's done it's going to fit it at the very least a double bed but probably a queen yeah it's going to be it's going to be big um and then then on to the next i do have a sweater for myself i want to make actually at least two but yeah we won't talk about that anyway i'm gonna play some puzzling games now give my hands a little break and uh wait for mr to get home that's really all there is to do now so i'll be back good morning everybody it is 10 o 2 a.m friday october 26th i think or 27th i don't know it's friday though it's family dinner night so i'm gonna go run out and get stuff for said dinner not going to do the full grocery shopping um because i don't want to and during covid bob and i got used to grocery shopping together and i kind of dislike going by myself now to be honest there's always stuff that he wants that he doesn't write down and he forgets to write down and i don't know to get because i don't have esp anyway and same for me there's always something one of us wants the other one has no idea so it's easier to just go together but we're having family dinner night i made a list i need to get some stuff for jr and um we're having pizza so nine times out of 10 family dinner night is pizza um it's been that way for the entire almost 40 years i've known mr b um he loves pizza sometimes we make homemade pizza sometimes we buy pizza we don't rarely we rarely anymore do frozen pizza that although that is the thing occasionally um today we're going to do pop and murphy's pizza which is a taken bake style pizza so kind of half and half sort of following somebody looks like they might be getting a ticket anyway um so i'm gonna go pick up the pizza i'm gonna get a few groceries gonna get some stuff for jr and i need to go on the buy nothing group today and see if anybody has a spare stroller because jr is big he doesn't fit in his old stroller anymore and it would be easier for everybody if we just had a spare stroller our house so um we don't need a car seat yet because i am not comfortable taking that baby anywhere in the car so there's that and we're babysitting tomorrow because mommy's got to work and daddy's working on their addition on their house so uh pops and i um our babysitting so here's that anyway let's go get our errands done see what we can see okay saturday afternoons just before five o'clock i have a vlog before now because we've been babysitting all day um both kids had to work and somebody had to watch the baby so um that was us so we are going to uh go grocery shopping at some point tonight i don't know if we're doing it right this second or i guess we're doing it now so and i have to work on or i want to work on my blanket some more we're gonna clean up the house a little bit and then head over to the grocery store i'll be back okay bob is downstairs watching tv and i am already in my pajamas because jr is already six months old and well he's and he's switching from formula to food baby food and well he spits up a lot so there's that and oh my god nailed a couple of times i am checking a couple of project bags where i'm kind of saving up yarn for more afghans yes this is going to be one of them i have and or was gifted or thrifted do they even make these yarns anymore this one is joann's sensations confetti and then there's also a ball of lion brand fancy fur anyway i'm gonna pair them up with something planar and at some point that's going to be another blanket um in fact i have some um yarn coming for that i ordered last night that'll be the main solid calm color there's some black in that ball in that bag but we'll see um then i have this which is just chunky yarn hold on let's go over here this is the one i need to look at because of course my glasses came off because why wouldn't they um will you stay there maybe hold on how about there that's a little better so i have a bunch of this chunky yarn from just different places um thrifted gifted i didn't i don't think i bought any of this um and i think i'm going to make it into a blanket like the one i'm working on now i'll put picture here um so i have random balls different kinds of stripey variegated tweedy they're all chunky so what i do is i do multicolor solid multicolor solid so i wanted to make sure um i have enough solids at least to get started so like these two could go i have a teal one that i'm going to order oh that's funny these two look like they're the same yarn gifted thrifted so interesting i need a purple i probably need more blue and gray or pink okay i have i there's yellow okay i have a clue now i also have this red i don't i don't know we'll use the red somewhere maybe we'll use the red with um rainbow this doesn't work all right so anyway that's going to be another blanket so have a good sale with some coupons on the mary maxine website so i think i'm gonna order just a few balls so now that i'm sure what colors i need anyway our day was mainly spent um taking care of thomas and paying attention to him and not really doing anything else which is as it should be and um then after he left we went grocery shopping real quick and i came home and put my pajamas on and yeah anyway he nailed my shirt i didn't even notice so i walked around the grocery store with babies spit up all over me yay me anyway tomorrow is going to be a quiet day at home so i'm going to work on my blanket and hopefully get some walking in we do have another storm coming in but i want to try to get some walking in before that um bob has um something he's doing with the kids and um they're going to go out and do that and they're going to do it like first thing in the morning and i am not about that i'm going to be here with my coffee and my crochet yeah anyway that's it for the minute i have lots of project bags filled with yarn ready to go and paintings i'm going to work on i'm getting commissioned for some journally travel sketchbook things from trips people have already gone on and i actually want to do one for myself for our virginia trip and i figured out where that safe place was in the art room where i put all my virginia bits and pieces and found it and put it over here on the table so if you're interested in fiber content sewing i've got a sewing project right here i've got a few of those lined up um i just finished making myself a halloween hairband hair barret um and um you know just wherever my creative muse takes me it could be anywhere if you're interested in contact like that then i sure would appreciate like share and subscribe maybe help that bell notification icon for new videos because i seem to be vlogging every wednesday but the other videos just come at random so you never know anyway uh questions comments or concerns are down below relevant links are in the video description and i do have a private facebook group for patrons and supporters of facebook messenger group so if you would love to be a patron and be into that chat and have ready access to me i also post things on a monthly basis in patreon for them um then that link is also down below i also have a facebook um art and inspiration group so if you'd like to be a part of that links down there all right that's it for now don't forget to go out have a great day have a great week do something nice for yourself because you deserve it i'm going to go order some more yarn i'll be back


We are Boilermakers, black and gold, founded in 1869 on agriculture and mechanics. Today, home to over 200 majors, more than 36,000 students and thousands of research projects each year. We are a nationally ranked and globally recognized school, smack dab in the Midwest, drawing students from more than 125 different countries, and creating a network of more than 450,000 alumni around the globe. We didn't choose Purdue because we thought it would be easy. We chose Purdue because we knew it was going to be hard. We are inventors and dreamers. We are problem solvers and doers. We plant our feet in the earth as we reach all the way to the moon. We believe that trains can be mascots. Fountain should be run through and that bell towers were meant to be built one brick higher, our Boilermakers.


So, this afternoon we will present to you measurements that we did on gold, so we changed from uranium which was in the program to gold. The lecture that we give is practically the same. Just that the element that we measured was different, we were not completely ready with the analysis of our uranium data. So, I will present the results of the transmission measurements and afterwards Kim will go through the capture measurements and then this afternoon we will continue also with the EHS and we will use the data, some data that I will show you here and that you will be processing then with the EHS gold. So, just to remind you what Carlos already gave you in transmission what we do is we try to determine the transmission in order to get access to the total cross-section. So, it is a very simple formula that is also why it is almost one of the most accurate cross-section data that you can determine. So, what you need to have is to such that you can apply this formula is that your measurements are done in a good transmission geometry and that you can realize by properly collimating just before the sample, just when the neutrons are reaching the sample and by properly collimating the neutrons with the detector. So, this is again a view on where we have, here we have the sample changer and here we have places to put background filters. Now, very important is that we alternate sample in sample out measurements and I will come to that later on. So, we do every ten minutes about the sample out and then ten minutes of sample in measurement. Here, you see the detector which is a lithium glass interlator and packed in a plastic bag in order to avoid a background from the light. So, here you see a typical measurement of a sample out and you can notice here the dips here which are due to fixed filters which you place in the beam. So, we have a sodium filter and a cobalt filter which we continuously keep in the beam in order to control the background. So, this is when we do a sample out measurement now. Now, then we place a sample in the beam, in this case it's an aluminium and a gold metal foil of 3mm thick and then you see here the effect of the gold and you see all these resonance dips which are due to gold. Now, we were mostly interested in this region here since we want to determine from these measurements the total cross section in what we call the unresolved resonance region. So, in order to do that we need to have a signal which is background free and here I show you how we determine the background. So, the total background is given here with a red curve and you see that it hits all these resonances where the product of n-sigma total is so high that neutrons cannot go through the sample and that they in principle cannot reach the detector. So, neutrons which are in the beam can in principle not reach the detector there. So, therefore we can easily use these dips here to estimate our background. And this background is a combination of different components. We have of course the time independent components which are coming from cosmic rays from whatever or from any other radiation which is not directly related to the beam. Then we have a rather important component which is related to the neutrons which are captured in the moderator and you have an n-gamma reaction in hydrogen which emits a 2.2 Mv gamma line. And this is for us this gamma line, this 2.2 Mv gamma ray produces almost the same amplitude spectrum as a neutron that we detect. So, we cannot differentiate in amplitude. We cannot do a gamma n discrimination in our detector so we will always detect this gamma ray and the component here is represented by this green curve here. Then we have an additional component which is due to neutrons which go through the beam, which go through the sample and they come into our measurement station and then they are scattered through the walls etc. And this is also a time dependent component which is represented here by the brown curve. So, we have done a series of measurements to characterize the time behaviour of these components by putting a lot of black resonance filters in the beam and now we know how these time components or these decay constants of these exponentials, we know their magnitude, we know these time constants. Now what changes when we, this is now the background when the sample is in the beam. Now, we of course have also to do the same game when the sample is out of the beam. And now look on the right hand side here. Here you will see the background, this red line here represented here with a green line and you see that it's different. And that is due to the fact that the sample changes the background. When the sample is in the beam, your background is completely different, but not the shape. So, what we do then is if we have to fixed black resonance filters in the beam, we can always adjust these amplitudes. And so we have always a very good handle on the background and we can also account for the presence of filters or the presence of samples in the beam. So then, if we do a background correction, sample in on the sample in and a background correction on sample out, and we correct also for that time effects, then we just make the ratio of the two background corrected spectra and we have our transmission. Just a division and that you will do this afternoon also. Now we put in just a k-factor here. And this k-factor is one and we put an uncertainty of 3% on it. And this here accounts for systematic effects on our background correction. So where did we get this k-factor from? Again, that is done by a series of measurements with black resonance filters and then checking the difference between the measured points here and the red line. And then we can do statistics on them and from that we determine the 3%. Then we have an additional factor and that is the n here, which is again one. Since all the spectra which we use in this equation, they are normalized to the neutron output of our machine. We have somewhere on the roof a BF3 counter which gives us the intensity of the neutron production. Now we each time divide the spectra by the neutron intensity. Now of course there is a variation on this counter. This counter is also not 100% stable and to account for instabilities on the normalization to the neutron intensity, we put an n factor here but this one has an uncertainty of 0.25%. And why is this uncertainty so low? That is because we alternate. We do sample in, sample out. So practically we have only to account for short instabilities, short time instabilities. It's not long time instabilities but short time instabilities. So in principle the n here accounts for the short time instabilities of the neutron monitor. So this is summarized here. So now we can produce our experimental transmission and we can account for systematic effects on the background and we can account for systematic effects due to the normalization to the B intensity. So from that we have the transmission as function of time of light and then we use them for two types of analogies. So where we can still separate the resonances from each other, we do a resonance shape analysis. So this is the so-called resolved resonance region and then we also use this, in this part here we can't separate the resonances anymore. There we do average cross sections and we do an unresolved resonance analysis. So let me take this picture again. So if you have the width of a resonance and you have indicated here by capital gamma and you have the distance between two resonances, the resonance region is that region where the distance between resonances is larger than the width. Now in the resolved resonance region there the resolution of the spectrometer is smaller than the width of the resonances. So we can separate the resonances. In the unresolved resonance region the resonance structure is still there so the resonances are still separated from each other but we don't see it. But there is still resonance fluctuations and that is very important to keep this in mind. So from the resolved resonance region what we do is we analyze single resonances and we try to determine the resonance parameters from a resonance shape analysis. And next week you will get some lectures on the R matrix theory. So what we do is we determine for example for this resonance here the 4.9EV resonance in gold from this transmission measurement we can determine both the neutron width which gives you the probability to form the compound nucleus and also is related to neutron scattering but we can also determine the radiation width even without doing a capture measurement since the radiation width comes from the shape from the width of this profile here. And this is so we determine from the transmission directly the neutron width and the capture width. We even don't need the capture measurement to get here the full resonance parameters. So in the unresolved resonance region here you see we can't separate them anymore the resonances so we cannot analyze for resonance parameters. So then what we do is we determine an average transmission and from this average transmission we determine average resonance parameters to reconstruct the cross-section. Now this is the equation for the transmission so the transmission is the exponential minus N the area density the amount the number of atoms per unit area multiplied by the total cross-section so if I calculate the average transmission that is given by this equation but the average transmission is not the exponential of N multiplied by the average cross-section or if you do a Taylor development of this one here and you average 10 then you get this expression. You see here that there is an additional term and if your cross-section is still varying if there are still fluctuations in your cross-section then the average transmission is not directly related to this term to the average cross-section. You need to correct for this additional contribution here and that is given here so the average transmission is not equal to this value here. OK so then the total cross-section cannot be calculated like this so here I give you if you would just take the logarithmic of the average transmission and divide by the area density that is not the average cross-section in the unresolved resonance region. So what we need to do is we need to correct for this and so what we do is this term here is nothing else than the average transmission divided by E minus N on the average total cross-section and that is given by this term so this accounts for still resonance fluctuations and these once we have this correction factor then we can calculate the average total cross-section. So and this correction factor can be calculated based on Monte Carlo calculation so what we do is we simulate a resonance structure based on prior information on prior average parameters so in principle we have to loop since we want to determine the average parameters but we need the average parameters to construct this correction factor so what we do is we build just a series of resonances and we reconstruct the cross-section and then we can recalculate then we can calculate this correction factor here but it's practically that is straightforward to do so once we have this correction factor so this is the one that you should not calculate this total cross-section but once we have this correction factor then we can calculate our average cross-section and you see that in this region here you would have a huge bias of about almost 10% so in your cross-section if you would not correct for this resonance fluctuations so that is a full bias it's not an uncertainty your correction is wrong your cross-section is then wrong but the further you go the less there are fluctuations in your cross-sections and then this this equation or the correction factor approaches once so this equation starts to be valid so yeah this is then the cross-section which we can get out so now we have to propagate of course the uncertainties so if we properly propagate these uncertainties which I said so decay 3% to end 0.25% and then the uncertainty on the area density of the sample which is about 0.22% we get a total cross-section average total cross-section as function of neutron energy in the unresolved resonance region with an uncertainty of about 1-2% now you can compare with data in the literature and you see that all these data that they agree very well so now we have of course to report this total cross-section and here I give you an example of how you can do it so we have the energy bins where we have calculated the average cross-section we report this correction factor that we applied and then of course we need also to report the covariance and for that we just use our HGS structure, our HGS formalism so we report the uncorrelated uncertainties and the correlated uncertainty components so in this case here this is the column with uncorrelated uncertainty components by just propagating the counting statistics due to the input spectra then we have the correlated component due to the K factor on the background very simple it's the partial derivative of the total cross-section here this equation versus K multiplied with the uncertainty of K then we have the uncertainty due to the normalization to the beam intensity which comes from the 0.25% of the stability of the beam monitor partial derivative of total cross-section with respect to N and its uncertainty and then the aerial density now you can easily verify where your biggest uncertainty component is coming from and so what we said is total cross-sections or transmission measurements provide you a very accurate experimental observable of 0.25% approximately that is the transmission but this 0.25% here is at the end the largest contribution to the uncertainty since practically the 0.25% is here on the average transmission but due to the fact that you have the aerial density included your total uncertainty here is dominated by this normalization and becomes about 1.5% on the total cross-section and that is due to the normalization to this 0.25% intensity but you see that with the AGS structure you can easily verify where your uncertainty components are coming from so the total cross-section the total uncertainty on the total cross-section here is nothing else than you just have to square all these terms and sum them and then you have the total uncertainty but you can also build the full covariance matrix so the S matrix in this case is 20 by 3 as a dimension of 20 by 3 so that is then the full reporting of the results now when you bring this data to XFAR you need also to provide all this information about your neutron source that we used to moderate the beam, the angle of our beam flight path with respect to the moderator, the filters that we used sample properties and detector properties so this all has to go also in XFAR and there is in the report we have there there is a template you just have to fill in the information that is related to your experiment so and that is what I wanted to say I want to make two remarks here so whenever you want to do measurements at our facility you can apply for access to our facility and you find information on our transnational access scheme on this website page we also have opportunities for students we provide financial support to participate in experimental programs and you can find information on that scheme here and then Tim will go now to the capture except if there are still questions so this year is basically this is a scheme to support it gives you travel support and accommodation support and it is meant for our master students our PhD students but we do not provide the PhD grant but if you are making a PhD and you think that it would be beneficial for you to add an experimental program to your PhD at our facility then we can provide you some financial support other questions?


Hello, can everyone hear me? Why don't you guys come on in here? Well, we're going to talk about containers. This is a pretty cool OpenStack Summit. This is Diamante's first OpenStack Summit. And we were kind of hoping that when we came with a container message that people would be interested. And it's been really cool to speak to so many people who are either already doing containers who plan to be doing it very soon.  Talk about your container requirements. We'd love to show you a demo and enter you to win a Ferrari drive for a day, if that sounds interesting to you. So I'm going to talk a little bit about why people are doing containers. This may be something that you've already seen around, but there are some real benefits to why developers are rapidly adopting containers. There's a promise of application portability. No one wants to be locked in to a particular cloud provider or particular vendor. You want to be able to deploy your application where you want it to be. There's a great developer productivity that comes from being able to decompose a problem into smaller, bite-sized chunks. And when you take those microservices, you can very easily scale out your application. So this is the promise of containers. And it's really very exciting. I encourage you to go to some meetups and then check it out. Like a lot of new technologies, though, there are a few rough areas. You look at how easy it is, really, to get application portability and to move your containers around. Google did a great job at GCP Next talking about some of this complexity. You don't just do your Docker run. You have to be able to deploy all the different components of the application, including all your infrastructure, your network, your storage, which are still thorny issues for a lot of people. And that takes a lot of time to actually get that done. Then you think about improving productivity. Well, now you start stepping through all the individual steps you need to actually deploy that container and make it operate at scale with the performance you require. And unfortunately, typically, when people get through this process, it's a highly manual process. People end up hard-wiring their systems, dedicating infrastructure for their containerized applications. They deploy individual databases, individual parts of their applications onto hardware. And at the end of the day, it does work, but it's very expensive. And you end up with that fixed configuration. And to me, that's the antithesis of cloud and containers and agility. So we think that there is a better approach. Diamante, we took a fresh look at what it means to run containers at scale. And we purpose-built what I believe is the only purpose-built conversion for structure for containers that allows you to rapidly deploy your containers into production. I'll give you a little demo to show you exactly how it works. The first thing we offer is virtualized I-O network and storage for every container in your environment so that you can guarantee the performance and the scale that you get for each of your containerized workloads. We provide isolation for the network and storage in the same concept as how your container runtime, your docker, your rocket, for example, provides a degree of isolation from CPU and memory at a process perspective.  We package our product as a converged infrastructure appliance that we cluster together for high availability and linear scalable performance. So come by our booth. We'll show you exactly how it works. The benefits of our approach gives you easy container migration with no vendor lock-in. There's no code changes required. There's no special drivers at all. You basically take your containerized applications. You deploy them with your open source orchestration tools. We work with Kubernetes, Docker, Mesos, and others as well. We make it very, very easy to set up your network and storage for your containers. It's done automatically, in fact. You don't have to manually tweak and tune your infrastructure as many people are accustomed to doing.  So very easy to get started, very quick to deploy your containerized applications. So we provide, and this is a shot of our graphical interface, and we'll talk more about this. We provide a very easy way to deploy network interfaces and storage volumes for each of your containers. Think about how you're going to introduce containers into your current environment. How are you going to make sure that your existing services like DNS and DHCP, load balancers and firewalls continue to work? It's actually a significant challenge. There's a lot of work going on, and you may see some others here talking about that as well. Well, we allow you to define in software however many interfaces you want for each of your containers. We allow you to define in software the storage volumes that you want for your containers. But we do it all with guaranteed performance so you know what you're going to get. The promise of containers is enabling you to deploy a very high density of workload, lots of containers on the same infrastructure. Well, that brings with it problems of noisy neighbors. Anyone who's ever deployed applications in a public cloud knows that one minute things are fast and the next minute it can slow down because of all those workloads that are beating against each other.  And if you look at the type of utilization you can get, right, typically what we've seen people doing is running their infrastructure at 10% utilization because they want to get that performance guarantee but the only way they can get that performance guarantee is by over provisioning systems and manually dedicating hardware. We allow you to run 80, 90% utilize because every workload, every container has guaranteed access to its network and storage IO resources. And again, this is all with standard Linux, no special coding, no special drivers required. We make it very easy for you to inspect the performance to be able to see what the configuration is if you ever need to troubleshoot or you want to create a new application, you want to scale your application. It's not easy in most environments to get visibility into what's going on, to be able to know where my performance bottlenecks are as I'm trying to scale out my application. Well, first of all, we make it automatic. As I'll show you in a second as we go through a little demo, we allow you to use open source APIs, vendor agnostic APIs to define your network and storage requirements. And then if you want to close the loop and actually see how those are being delivered, see how your application is performing. You can do that through our graphical interface. You can export that information to third party systems like elk or any other monitoring system you may have. So let's take a look at how do we do this? How do we do this in a way that's truly vendor agnostic, no lock in, no customization? Well, the first thing is we allow you to define your networks such that they'll work with your existing data center environment. We have a very simple command line where you can define your interfaces. We then allow you to create storage volumes. Very, very simple approach to get a block resource that you know is going to scale. This is an example of open source orchestration working with Kubernetes. We've contributed code to the Kubernetes 1.2 release that came out last month that allows you to take your existing pod definition and simply add to it vendor agnostic open source options to define the performance requirements, the quality of service performance tiers that you have for network and storage in that container. And now what do you do? You use your open source tools to deploy the application. There is no special command required to get those applications deployed. Now, in a real environment, you're going to have multi-tenancy. You're going to have many different applications operating at the same time.  Well, what happens? Are we going to conflict with each other? Right? Is your application going to run slower? Is my application going to start running slower? Well, every application in the Diamante environment operates with guaranteed performance. And what you can see on the screen is you can see that each container, here we have a multi-tenant environment using standard MongoDB, Docker images, MySQL, Nginx, whatever you want to run. Each of these containers has an assigned SLA or a performance tier. So they all coexist and they're all sharing very high throughput IO. We're delivering literally hundreds of thousands of IO's per second, all in a guaranteed environment for each individual container. And the way that we can do this is because of our appliance model. We are able to create these virtualized resources, network and storage, connect them to the Linux operating system in your choice of Linux and then map those into the container namespace so that each container has direct access to resources that you know are going to perform at the level you require. What does this really all mean at the end of the day? So there's no more manual tuning. A lot of us, you know, IT background, we're used to months long efforts of customization and special deployment procedures. With Diamante, you use your standard open source tools, there's nothing special or proprietary that you're doing and you're not spending months tuning performance. You simply request what you want in a simple declarative model and you get it delivered to you literally within seconds. So we work with some users who spend a lot of time custom engineering IOPS and latency and network bandwidth and all these other complex topologies. We break it down to a few minutes to get set up and literally zero seconds trying to extract that performance level that you're looking for. All of this with standard runtime, your existing applications. What we've also seen unfortunately is that when people do this level of customization, they lock themselves into a particular architecture and so six, 12, 18 months later when things change, they have to start from scratch. They do a forklift upgrade, they bring in whole new infrastructure and they start again. With Diamante, you don't do that. You need more performance, you ask for it. You say, I need more storage, I need more network and you get it because it's all controlled in software and enforced in our appliance. We also looked at the performance of data. You know, in a traditional shared storage model that many of us are familiar with, iSCSI, Fiber Channel, whatever you may be using, NFS to try to get access to your data from your application. You know, best case you're looking at a millisecond of access time, you're looking at 90% IO weight, which is slowing down your application. That's why people over provision, that's why people are running a 10% utilization. We take a zero off that, we divide it in 10. We give you 100 microseconds of shared storage access. So if you want to be able to deploy an application literally within seconds to be able to get higher performance than you have today, you can take our approach, stop by and we'll show you exactly how it all works. But you're able to get that with full mobility. You're able to deploy your application anywhere in the Diamante environment and get access to your data protected with low latency and guaranteed performance. Because you're not over provisioning, because you're able to take advantage of what you're actually buying, right? You're not buying something and only using 10% of it. We're delivering 6x the utilization. So it's fewer things you have to manage, less overall cost, less power, less overhead in your data center. So this is how we talk about a standard based approach where you can migrate your containers, keep them as is, you don't have to change anything, but you have the ability to get much greater performance, much faster deployment without ever being locked in. You can put your containers on Diamante. If you like it, you can stay, if you don't, you can leave, you haven't lost anything because you haven't made any changes or any customizations to your application. If you prefer a particular open source orchestration or you build your own, we work with that as well. We have open APIs, we are committed to the open source ecosystem, we contribute code on a regular basis to make sure that we can extend the vendor agnostic notion of network and storage requirements in this container landscape. Think about the time to market, whereas it typically takes people weeks and months of planning to be able to actually deploy their application at the level of scale and performance that they require. We make it very easy to do within seconds. So it's much easier to get your application deployed and operating as you need it to be. We're working with users in the media space, in the financial services industry, in the service provider industry, in the web infrastructure industry. These are all users who care about deterministic results, getting their applications deployed, making them successful without having to re-architect and constantly retune their infrastructure and their applications. We'd love to talk to you further. We'd love to learn more about your containerized requirements. We'd love to enter you a chance to win a Ferrari for a day. So please come by, yeah, you like that, there we go. So come on by, A-15 right there by the entrance. Please stop by, we'd love to hear what you have to say. And I'll be around here if you wanna ask any questions. Happy to take those questions. Thank you very much.


So, by now you know that buttoin is more stable than but1in, right? This is because in but2in we have these hydrogen atoms. We in fact have 1, 2, 3 and 4, 5, 6. We have 6 hydrogen atoms that are attached at this alpha position that can undergo hyperconjugation with this double bond compared to only 2 hydrogen atoms in case of but1in, right? So therefore these pi electrons can get delocalized more in case of but2in making this molecule more stable, right? Now one of the ways in which we can actually test this experimentally is by checking for the heat of hydrogenation of but1in and but2in. So what does this heat of hydrogenation mean? Well, hydrogenation simply refers to the addition of hydrogen and it turns out that whenever we add gaseous hydrogen to alkene, it turns out that some amount of heat is always released. Now why does this happen exactly? We will come to this in a short while. But if you look at this heat, amount of heat that is released, this heat of hydrogenation, then you will see that these values are somewhat different, right? If you come and take a look at but1in, then the heat of hydrogenation of but1in is 30.3 kilojoules per mole minus of 30.3 kilojoules per mole. So this basically means that 30.3 kilojoules of heat is released. Then I add gaseous hydrogen to one mole of but1in. Now if you compare this with the heat of hydrogenation of but2in, both the cis and the trans form, let's not worry too much about the cis and trans right now. But if you look at the heat of hydrogenation of but2in, you can see that these values are slightly lower, right? It's around 28 kilojoules per mole. So how does this heat of hydrogenation relate to the stability of but1in and but2in? Let's find out in this video. Now whenever we add hydrogen to an alkene, let's say but1in, we actually get an alkene, in this case we are going to get butane. Now this reaction is actually really slow and we need to add some catalyst like some finely divided nickel to drive up the rate of this reaction. And we are going to talk about this in detail, how this reaction exactly works in a later video. But the bottom line is what actually happens is that these hydrogen molecules, this come and collide against this double bond. And this leads to the formation of new carbon hydrogen bonds along with the breaking of these carbon carbon pi bond and these hydrogen hydrogen bonds. So this leads to the formation of an alkene. So we have said that hydrogenation of alkenes is always exothermic, right? So how can we be so sure about that? Well, if you look at what's going on, you'll see that we are actually breaking this carbon carbon pi bond. So we are actually breaking one carbon carbon pi bond. And we are breaking these hydrogen hydrogen bonds, one hydrogen hydrogen sigma bond. So we are breaking one hydrogen hydrogen sigma bond. While on the other hand, we are forming two carbon hydrogen sigma bonds, right? So we are actually forming two carbon hydrogen sigma bonds. Now as you must be aware, it takes energy to break bonds but energy is released in the form of heat when new bonds get formed, right? You must also know that it's actually far easier to break pi bonds compared to breaking sigma bonds. So therefore, because we are breaking one pi bond and one sigma bond but forming two sigma bonds in its place and these carbon hydrogen sigma bonds are really strong. They're almost as strong as these hydrogen hydrogen bonds. So therefore, the amount of energy that's going to be released is going to be greater than the amount of energy required to break these bonds, right? So therefore, the change in energy, in chemistry we actually calculate these changes under constant pressure and we call it the change in enthalpy. The change in enthalpy is always going to be negative, right? This reaction is always going to be exothermic as it involves the breaking of these weak carbon-carbon pi bonds and the formation of really strong carbon-hydrogen sigma bonds. Now to understand these changes in enthalpies, let's simply call this the change in energies. A good way to picture these changes is in the form of an energy diagram. Now because this reaction is exothermic, energy is released during the course of the reaction. So this means that the energy of the products that are formed has to be lower compared to my starting material compared to the energy of my reactants, right? In other words, because change in energy is negative and change means final minus of initial. So the change in energy will be the energy of the products minus of energy of the reactants because this term is negative. So this clearly shows that the energy of the product has to be lower compared to the energy of the reactant, right? Now we can make sense of this data that I showed you earlier. These are experimentally determined values and this shows that the heat of hydrogenation of Butte 1 in is minus of 30.3 kilojoules per mole, right? So this basically means that the energy of my product which is Butte is lower than my starting point is lower than the energy of my reactants by 30.3 kilojoules, right? So this energy difference is going to be 30.3 kilojoules. Now if we turn our attention to the heat of hydrogenation of Butte, let's consider this trans Butte for reference. Its experimental heat of hydrogenation is only 27.6 kilojoules, right? Its only minus of 27.6 kilojoules per mole. So what happens when we hydrogenate Butte? Well if we add hydrogen to Butte, Butte 2 in, then even out here these hydrogens will get added to this double bond and we are going to get Butte, right? So even in Butte 2 in, we get the same product Butte as in case of Butte 1 in, but the experimental heat of hydrogenation this time turns out to be lower and its 27.6 kilojoules, right? So in case of Butte 2 in, the energy of the product which even out here is Butte, so it's still going to be at the same energy level, the energy of the product this time is only 27.6 kilojoules lower than the energy of the reactant, right? So this means that the energy of the reactant which is Butte 2 in has to be somewhere around here, right? So this energy diagram is going to look something like this and the difference between these two energies which is nothing but 30.3 minus of 27.6, so it's 2.7 kilojoules. This has to be the exact same energy difference even out here. So this shows that experimentally Butte 2 in is more stable, it has less energy compared to Butte 1 in, right? So what's going on? Why is the heat of hydrogenation lower in case of Butte 2 in compared to Butte 1 in? Well, the answer to this question as you must have guessed is hyperconjugation. Even though in both these cases we are breaking this carbon-carbon pi bond and replacing them with carbon hydrogen bonds, but because of hyperconjugation this pi bond in Butte 2 in is more stable, it's more delocalized. So therefore it's more stable and difficult to break, difficult to break. So therefore the amount of energy that's actually required to break the carbon-carbon pi bond out here is going to be higher compared to this one, right? So even though the amount of energy that's released is almost the same on forming this Butte in molecule, but the amount of energy that's required to break this bonds is going to be slightly higher in case of Butte 2 in, right? So therefore the total energy change, the total heat that's going to be liberated is going to be slightly lower in case of Butte in as slightly more energy is consumed during the bond breaking process of Butte 2 in compared to Butte 1 in. Now what about the differences in heat of hydrogenation between the cis and the transform of Butte 2 in? Now before you figure that out, let me give you an important hint. In cis-Butte in we have these alkyl groups that are placed closer to each other. So think of this as electron clouds. So these groups they can ripple, they can suffer repulsion thereby increasing the energy of the molecule and making it relatively less stable. On the other hand, because these groups are placed further away in transform, there is no such repulsion. So the energy of the transform is relatively lower, it's more stable compared to the cis form. Now that you have this information in hand, which amongst these two do you think will have a higher heat of hydrogenation? You can pause the video and think about this for a moment. Well, in both these cases, it doesn't matter if I take cis-Butte 2 in or trans-Butte 2 in, in both these cases on adding hydrogen, I am going to get Butte in. I am going to get Butte in both these cases. So therefore the energy of the product that is going to get formed is going to be the same. So if I look at my energy diagram, the energy of the product is going to be same in both the cases. But because cis is slightly higher in energy due to this repulsion between these alkyl groups compared to the transform, so therefore the heat of hydrogenation, the heat of hydrogenation in case of cis is going to be slightly higher compared to the heat of hydrogenation in the transform, right? In fact if we look at the data, let's get our data out. You can see that experimentally trans-Butte has a slightly lower heat of hydrogenation compared to cis-Butte, right? So therefore we can now go ahead and make a rule. We can say that if the product formed on the hydrogenation of two different alkenes is the same, then more stable the alkene, lower will be the heat of hydrogenation, right? So we can say that if the products formed are the same, then more stable my starting alkene, this means lower will be the heat of hydrogenation, lower will be the heat of hydrogenation, right?


My RV mission to explore new worlds to seek out new life and new civilizations and to go Where no space is left behind. Let's talk about RV storage hacks Hey everybody, it's Robin with creativity RV and when you live on the road space is at a premium So today I'm gonna show you my favorite small space storage hacks The first hack is right behind me I realized I had all this space behind my couch and a bunch of books stuck up in a cabinet and That I couldn't even see so this is what I came up with. I figured out that I had this ledge behind my couch That wasn't being used and I found these little storage containers that fit back there and hold a whole bunch of books So I can see everything that I want to read and they don't fall over while I'm traveling. The next hack is to get high Not that kind of high Most of us have a bunch of unused space in our cabinets like I did for my canned goods So I just took some regular cardboard and I made these separators and I have different types of products in each slot So I actually know when I'm running low on something and then when I travel they don't go anywhere And I have this weird cabinet in my bathroom I couldn't figure out what to put here and then I realized I could use it for paper products Oh, yeah, I got a bunch back here Hored in the toilet paper For stuff like this I do like to keep items in their packages because they create a natural barrier so things don't fall over while I'm traveling The next hack is to keep things in Perspective if you wear glasses like me you probably can't find them I was always losing mine until I came up with this hack I realized I had all of these extra command hook cord keepers and I could just pop one up on the wall like this and Then my glasses would hang right in there and I do this all over the house The next hack is to get boxed in now You don't have to buy storage containers for this you can use whatever you have around your house You can use an old frozen dinner container or whatever you might have for me. I have these old baskets They weren't doing anybody any good inside of a drawer So I hang them with command hooks right here on the bathroom wall I have some wipes and some q-tips and body wipes and lotion and then over on my bathroom cabinet I have these other skinny ones you can see that they are attached to the wall with another command hook So these don't move while I'm traveling and now I don't have to dig around in a drawer for these things So like toothpaste toothbrush micellar water the stuff that I use every day and all boxes are great for just Organizing drawers like keys and glasses and like Kenny Rogers said you got to know how to fold them Right I've done a video on this before but if you can learn to fold things in a little tiny satchel like this You can fit a lot more stuff in your drawers, and if they're not stacked on top of each other you can see what's there over here I Have t-shirts and I can see what every single one is and I can pull one out Without wrecking everything else if you're still short on space Just hang in there for me I wear hoodies a lot, but they take up way too much room inside of a drawer or a closet So for me I hang them all behind the bedroom door just on some removable command strips Then when the bedroom door is open you don't really see them The last hack is just channel your inner MacGyver now I'm not talking about making a bomb out of a piece of chewing gum and some string here I'm saying figure out what needs to get done around your house and think about what you have just laying around that can Do it behind me is a roll of toilet paper now My RV did not come with a toilet paper holder attached to the wall But even if there was one I wouldn't have kept toilet paper on it because my cat would just eat it So I needed a way to store my toilet paper that was high off the ground This basket had these weird hooks that I never used for anything if I tried to put a towel on it They just fell off But then I thought what if I took a little baby bungee and Hung it right here. If you don't have something like this You can just put two command hooks up on the wall and put a string through it. Voila toilet paper holder I tell you life is so much easier in a small space once you get the storage figured out I hope you guys can use one or two of these if you have a favorite hack for small space storage Put it down below. I would love to read about it I hope you're all staying happy and healthy out there and doing something that you love everybody Have happy travels and be free


Yeah, obviously with kids, especially grasswoods, football, I think, especially if you're not in the academy or outside the academy, you've got different levels. And the key drive, in fact, for every session is fun. It's fun and learning, and you need to find the right mix to do it. If you give too much too soon, the quality won't be there, so it doesn't really have any effect. So it's a fine line. If you have selected academy players, it's like driving a car. You know, the better the players, the faster the car, the faster you can go. So the players will always respond to the environment you create. You as a coach, you are the one that has to put the menu together that is right for the players you're working with. I think the main thing is to know what you want to do, because it's not the same to be an academy coach than to be a professional coach than to be a... So because if you want to be an academy coach, you need to be patient. You need to teach the players the first skills, the first kind of things. And if you want to be a professional coach, it's going to be more difficult, because there is just one or two leagues in each country, so we are 40 coaches just to manage, so it's difficult. And then if you decide to be an academy coach, to be clear that you need to, again, to be patient, to teach the players. And again, for me, the main thing is to know clear what you want to do. And the main thing for me, as I told you at the beginning that my father told me, is to be yourself. And to do the things that you think that they are the right thing for the team. Because at the end, you are the reflection of the players. And for me, the main thing is when a team on the pitch reflects the personality of their coach. In terms of their own development, to go and watch as many good coaches working as they possibly can. And try and analyse what those good coaches are doing. And if they get access to them, ask them why they did things, how they did things, how they got to that particular position. As far as working with young players, first of all, they have to understand that the young player won't make mistakes. There's absolutely no problem. There was a young lad out there who looked a little bit upset when he'd lost the ball and it resulted in a goal and he could have played forward. He looked as if he didn't mean that to happen. He was working really, really hard. So the important thing is that he doesn't go home thinking, you know, my world's just ended because it hasn't. They make mistakes, they hopefully learn from those mistakes. So you have to understand that the game that we see as coaches, when we're not right in amongst it, is an awful lot easier than the game that they're actually playing in. And one of the things I can tell you for sure about when I've been coaching is I've never made a bad pass. You know, I don't make bad decisions when I'm standing on the sides. I know that you should pass at this moment at that angle at that speed. It's really easy. It's really easy. I made plenty of mistakes when I was a player. So it's vitally important that coaches recognise that. It's also important to recognise where the players are and that if the players can't do something, you know, and they found that difficult today, certainly as we moved on from the earlier practices, if they can't do it, then it's vitally important that the coach looks at a way of getting them to a position where they will be able to do it. So for me, looking at the boys there, I would have to take them back to a more technical practice and embed that in before. So my first practice for them leading up to what happened at the end would be very different. How long will that take? I don't know. It depends on the players. I've been really fortunate in that I've worked with some very, very strong groups. And those groups have moved on really quickly. And I've worked with weaker groups who have taken longer to get to the same position. And that's the way things are.  Well, the job with the coach is to make the players better and hopefully get them to a position where they can do it. And yeah, you're not a magician, but I do believe you can help players to become better. They might not become good enough for where they want to get to and where you want them to get to, but they can certainly improve. And so patience, looking at yourself as a coach and finding another way, finding a different way of helping the group, but also individuals within the group because they're all different. Yeah, I mean, I think for me it's about, I know sometimes for those people it's hard to have the time to really spend lots of time thinking about coaching, but I think the time that you have, for me, is just get as much resources as you can just to increase your understanding first and foremost. The second thing for me is that the sessions don't have to be complicated. You can take, especially for the younger age kids, you can take really simple games and just put them into a coaching session and just utilize them to inspire. For me, it's about positivity with the young players. It's about creating a situation where they're not fearful of making a poor pass. They're relaxed on the ball. They enjoy it. They're infused by it first and foremost. And then I think as you start to then advance as a coach, the one thing I would say then is try your best to try to make the practice have some semblance of a game. So if you're going into nine V9 games and you might be playing three defenders, three midfielders, three attackers as you set up, you know, try and use some of those games to teach a little bit of spatial awareness. You know, how can we spread out and create a bit of space? You know, how can we utilize that space a little bit? And because then they can use those principles to take through as the kids get a little bit older and need a little bit more understanding of the game in terms of those principles. But enthusiasm for me is you can't beat it, you know, regardless of your knowledge of the game. For me, absolutely the best information will be the game is changing, you know, and certainly a thirst for knowledge, a hard work putting in the extra hours, doing the over and above. And it's, you know, there are, you know, two types of learnings.  And certainly to try and put as many hours as you can, you know, on the training pitch, because that's where, you know, where you build up your confidence is our taking sessions. And sometimes that's very difficult. It's very difficult for a young aspiring coach that wants to coach, but isn't managing a team, you know, maybe doing part coaching with the team. And so it's trying to get as many coaching hours in as you can. And sometimes that might be, you know, dropping down the age levels. And that might be somebody that really wants to be coaching senior players, but it's taking, you know, the under 18s or the under 16s. Now, for me, as opposed to waiting for that opportunity and not getting them hours on the training pitch, I think it's important that they do. And if that means dropping down a level to perhaps where they want to be coaching, then for me, it's vitally important to get them coaching hours in, because that's what, you know, builds up your confidence. Going into management, what builds up your confidence is all of them team talks that you have to do. So whether it's a senior group, a girls group, a ladies group, men's group, then pre-match talks, halftime talks, debriefs. So spend as much time as you can and don't be afraid that if you can't get what you want to help somebody else out, take another team that you perhaps didn't want to take, but it's really about putting in them hours. And of course, that thirst for knowledge. We're near also where it's important to get your badges, your qualifications, because in this day and age, it's very much a requirement. I think you've got to see yourself and say, do I add value? As a coach, be it a Academy Director or a assistant under 11 coach on the night, whatever it may be, do I as an individual add value to this system, to this development model? What do I have to do to make sure I keep adding value? And that's what I always found. You have to challenge yourself. You have to go the extra mile. You may be the last one at the session locking the gates at 10 o'clock. You may be the first one there in the morning. Whatever it may be, you add that value as basic as it may sound, take the visit, go to the course, I'm tired. I need to see the family. But you have to go and get yourself qualified as best you possibly can. And the moment you stop pushing, others will go past you. The moment you stand still, others just fly past because it's the world's game. Everyone wants to be involved in football. They want to be in the highest possible position. They want to keep pushing forward and they'll show a hunger and an appetite to educate themselves. You have to make sure you do the same. But if you can turn around and say, I add value by doing this, then I think you've been a good place.

Included in this week's updates from the Circuit Python team, Dan now has HCI underscore BLEIO working completely for Nordic UART as a peripheral. This means he can use the Bluefruit LE Connect app to talk to Circuit Python over BLE using an ESP32 co-processor available on, for example, the M4 Airlift or the PyPortal. It is satisfying to finally see an end-to-end test working after being heads down in this code for weeks. He has a little cleanup to do, but will be submitting a PR soon. Jeff has continued working on the Sharp Memory Display PR, which was recently merged. STM32 support for SDIO was also belatedly merged after some neglect. He also did further work to reduce the memory usage on M0 boards so that we could add a new Japanese translation of the core. Melissa finally got the Matrix Portal library merged in and now it is part of the bundle. If you're interested, you can look at it on GitHub. It has been used in a project that has a learn guide written. You can check out John Park's on-air sign. She's been working with John Park to write a couple of additional demos for using this library, so be sure to catch John Park's workshop each week to learn more. Another big project that she's been working on is to try and get the STM32 MP1 working with Blinka. She spent some time building a custom Debian image so that installing Blinka on it would be much easier. Although the image currently isn't working, she is working with an engineer on the DigiKey forums to figure out the issue and then she can resume getting it working. In the meantime, she is working on porting the PyTFT installation from a shell script over to Python so that it will be simpler and easier to add new displays and maintain.

a long time and this is going to be a great experience. Yeah, so let's talk a little bit about the Sitski here. It is aptly named, right? And this is for people who use wheelchairs and need other limited mobility. And as you can see here, there are these two little outriggers here. And if you've ever been to Hawaii, you're familiar with the outrigger boats. It's the same concept here. Instead of having two floats to the side to stabilize the water, there are two little pieces of equipment here that stabilize on the snow. And the participants this week, they're able to lean left and right. It helps stabilize it. Some folks, when they go down, they have a ski instructor behind them. It's almost like Santa Claus style, right? Like, that's the best way I can describe it. People are laughing. But, you know, when you go down, there's various levels of mobility here. And what this week is all about is testing the limits and participants are going to be going down. They're going to be, you know, building up to as much independence as they can get. And you've been able to meet with some of the participants this week. What's that been like? It's been great. I have seen veterans here that I saw at previous events, the golf clinic that we also co-sponsor with the VA. And so it's old friends, new friends. It's been wonderful. And it's encouraging to see them excited to get out and do the events here at the snow. Absolutely. It is exciting. I'm excited for you. I can't wait for you to go down to see how it's all going to be. We'll talk to you down there. And again, this event is co-presented by the VA partnership that goes back decades. We could not do the event without them. This is Matt Sancing. Make sure you're following along at winnersportsclinic.org for all of our coverage and tune in for more coverage.


Grass trimmers are great for tidying up the edges of your lawn after mowing, and they're available in three different power types. Corded grass trimmers plug into the mains electric, so are ideal for trimming and edging smaller compact gardens. Cordless grass trimmers are better for larger gardens, allowing you to move further from the house or power source, and there are also petrol power trimmers, which are the best at tackling long grass, coarse weeds, or rougher vegetation. They're great if you have a wild garden to keep looking nice.

I'm Paul Gennaro, and I'm a Navy veteran. I started out as an air traffic controller, stationed at NAS Norfolk, 88 to 91. Then I switched to a print and broadcast journalist, we used to call it a JL at the time, and I did that for the balance of my career. I was stationed at Naval Communications Station, Harold E. Halt in Xmouth, Western Australia, and then also at Submarine Base Pearl Harbor. One of the things I've learned as a hiring manager is you can look at a resume and you can take some things away from it. I've seen people that have a bachelor's degree and two master's degrees, and then you hire them with your very enthusiastic, and they don't necessarily deliver to your expectations. A lot of what it really comes down to is character. Anybody that's gonna come into a new organization is gonna have to learn that organization. So what's their character, what are their values? One of the things that I've found is people that come out of the military, for the most part, have exceptional leadership skills, have exceptional work ethic, understand that it's about teamwork and collaboration, doing whatever it takes to get the job done. And I'm the first, I joke with my team, to say I'm not the smartest guy in the world, but one of the things I do think I bring is the ability to do whatever it takes to get the job done, a sense of duty, a sense of overcoming whatever the obstacles to the mission are, and I think the folks that I work for appreciate that. I was fortunate to be there during the 50th anniversary of the attack on Pearl Harbor. So I had two Navy grandfathers. One was on the USS Shea during World War II. They took down eight planes, had a kamikaze, hit them, and just did phenomenal things and survived. Another grandfather hit the beaches at Iwo Jima with the Marines. So I had a lot of respect and admiration for those World War II veterans. When they would come back, and you'd be able to take them on a tour of this base 50 years later, I still get chills thinking about it, because the sense of duty, the sense of service to the country, and it's one of the things I love about working for AECOM right now. We do a good amount of work for the US government, the US Navy, the Department of Defense. After 9-11, we were the program manager that helped rebuild the Pentagon and get it back up and running a year later. That's cool stuff to do.
