The Bumble Nums

Today, the Bumble Nums are going to make

Underwater Watermelon salad

But what's the secret ingredient?

One big underwater watermelon

Just past the orchard by the pond,

the Bumble Nums are getting ready to go diving for underwater watermelons

There's Grumble.

Yum

There's Humble

Yum yum

And there's Stumble

Uh…Stumble

That's better

Okay, Bumble Nums, we need one big underwater watermelon

for our underwater watermelon salad

And where do underwater watermelons grow?

Under water, of course!

Okay, Bumble Nums, on the count of three

1…2…3..

Yum, yum, yum

The underwater watermelons grow way down at the bottom

Yum yum

Deeper, deeper, deeper, still

All the way down to the very bottom

Look, there it is

The underwater watermelon patch

Now to find a big underwater watermelon

Yum

You're right Humble,

that's a big underwater watermelon

Yum

Yes, Grumble, that's an even bigger underwater watermelon

Yum yum yum

Yum

Wow, Stumble, you found the biggest underwater watermelon of all

Yum…yum…

Hmm...

I think that vine is too strong

Grumble has an idea

Yummm!!!

Splash-tastic!

Now do you have the big underwater watermelon?

Now that we have the secret ingredient to make our underwater watermelon salad,

it's time for the cooking countdown!

10…9…8…7…6…

5…4…3…2…1

Bumble Nums, you've done it again

That underwater watermelon salad looks pretty tasty

Mmm

Mmm

Mmm

How does it taste Bumble Nums?

How To Use A Laser Cutter - Lightblade 32 The Russ Formula for Successful Photo Engraving - Duration: 43:45.

welcome to another Lightblade Learning Lab in a fairly recent session I attempted to

give you all the knowledge I had about photo engraving now I've since

been able to learn a little bit more and rationalize all that I've learned into a

fairly simple set of instructions now there are some calculations in there but

nothing difficult and what I'm going to do today is to summarize in just this

one simple session how to go about producing excellent quality photo engravings

these are basic rules and they will guarantee to get you good quality product

but you might decide to veer away from those rules and experiment for yourself

that's your choice I'm only giving you the foundation upon which you can build now

to go along with this session we have a two-page document here which summarizes

all the steps that I'm going to demonstrate to you today so in

conjunction with some of the fiddly details that I'm going to show you on

the video you can go through the basic steps here with this document that will

be published on the Thinklaser website now today's session

we'll start right at the beginning and we're going to do every step of the

process but in future you won't need to carry out every single step of this

process only some of the steps because once you've gathered the information

today it will be valid for the future step number one is to choose the lens

that you're going to use now the one thing that you will find about doing

engraving work

is that the nozzle will tend to get sticky around the outside because of the

way in which the fumes will come upwards and stick to the outside of the nozzle

so from time to time you'll need to inspect the nozzle and maybe clean it

with some acetone now before you do that you might want to check that you've got

a nice clean hole in the end of your nozzle and you can do that with a two

and a half millimeter drill literally just make sure the nozzle is clear and

then we'll just clean the outside of the nozzle there now the inside does tend to

get a bit fogged and messed up but it's not essential to get in there to clean

it although from time to time I do just to take the debris off the inside of the

nozzle as well your Thinklaser machine will be supplied with three lenses it has a 2

inch lens which to be honest is normally a very good quality meniscus lens now if

when you look in there you'll see that it's a greeny color and if you hold it

up to the light you will not be able to see through the lens and that's because

it's made of a material called gallium arsenide now most lenses that you can

get the cheaper lenses are made from something called zinc selenide which

work perfectly well this is a good quality lens and the meniscus lens helps

to focus the light down to a slightly sharper point so

whatever lanes you're using and I would normally recommend for engraving work

the use of one a half-inch lens but sadly this system does not allow you to

use a one and a half inch lens a two inch lens will be perfectly okay you're

pretty able to produce perfectly good results with a two inch lens but you

would get slightly better results with a one and a half inch lens and if we get

time I have got an adaption for this system which will allow me to put one

and a half inch lens in here and we'll see what the difference in the quality

of the pictures are and I think you'll see that there isn't a huge difference

so step number one Choose your lens and make sure it's in good working order clean

and the next thing is to make sure it's correctly focused now I've shown you

this photo engraving of one of my old girlfriends on previous occasion it is

almost the perfect formula but not quite now as

I've mentioned before this binary picture is composed of just dots there

is a white background and dark dots now it looks as though we've got lots of

different shades of dots in that picture not true

they are literally one color dot but it's the mixing of the white background

with the different densities of those dark dots that creates this impression

of a grayscale now that's a very very important thing to remember the white

background is very important if you make the dots too big or you overlap the dots

because you try and make the picture too higher-resolution your eye will not be

able to sort out a white background it will just have a series of dark dots and

so the grayscale effect that you're looking for

disappears today is all about the rules for getting the features of this picture

correct the dots the size of the dots the power of the dots and the resolution

of the picture that you start with now with a card which is what this is or

leather a natural leather maybe a piece of MDF and all those sorts of

materials wood they're all what I call organic materials they will burn and

they will burn with a brown mark which is great because Brown is quite a dark

mark so we can have a dark dot on a white background which is exactly what

we want to get the good quality picture

now when it comes to what I call mineral materials slate stone granite or

plastics like maybe clear acrylic the situation is different we do not get

black dots we get a black background or a clear background with in the case of

acrylic but we get white dots now that means to say that the picture has to be

converted into a negative before you print it so something else that we're

going to talk about along the way for the purpose of this exercise I'm going

to be using a white card it's about one millimeter thick and to be honest I

think it's the sort of card fairly soft card that you probably would make beer

mats of it's not high quality but it's nice and soft so it's actually very good for

doing pictures on and it's not expensive to buy

now it is important that you use a piece of the material that you're going to

work on to do these settings because what we're going to do now is find not

only the focus but we're also going to find the size of the dot and to do that

we need to be working on the correct material because different materials

will produce different size dots

okay now my focus gauges are basically this one is millimeters and this is 0.5

of millimeter so for instance this one runs from I think one to 20 and this one

runs from 1.5 to twenty point five because I've added an extra half a

millimeter onto the bottom so they're very simple gauges to make

and what we're going to do is we're going to lift this up

and we're gonna drop it down initially onto the 8-millimeter step

we're going to run my test program and that's it that's all the program is so

this is seven point five just drop it down on to seven point five now I'm

going to do a manual inspection on these using this device here now this is

something called a linen gauge and it's a very handy device that you will

probably need to measure these and to look at these with now this is easily

available on you get it off eBay for about five pounds for a plastic version ten

times magnification which is absolutely super for doing this job so I put all

the details in my separate write-up. No for 6.0

not really for 6.5, 7.0 looks a lovely clean set of holes with dots, 7.5 not bad but

in general I would think I've got a crisper set of holes at 7.0 & 8.0 that's not

particularly brilliant either but we'll see those under the microscope and

you'll see what I mean now this little pattern is very carefully designed to

tell you all sorts of things the first thing it will do it will enable you

to estimate the size of the dot and I would say that we are looking at dots

that are probably 0.2 diameter and I'll explain more about that when we see

them under the microscope now before I try and describe what we're seeing under

the microscope let's just take a look at the pattern that I laid down as the

basis of the test what we've got here is a set of pixels these are very carefully

sized each one of these pixels or spaces on the bottom line is 0.1 of a

millimeter let's take the bottom line for example if I see a dot then a space

then a dot and the space is the same size as the dot then I can estimate

that I've got 0.1 millimeter dots now if the dots touch on that

bottom row then it can only be because the dots are 0.2 diameter now we can

apply the same principle to the next two rows of dots so if I get point two dots

there will be a dot a space a dot a space a dot a space and the space

between the dots should be the same size as the dots themselves so that will tell

me that I've got 0.2 dots and then obviously if the dots are touching then

it means those dots are point four diameter and of course between the point

two and the point 4 we can estimate a 0.3 dot. so i don't expect anybody

to be using point 4 dots but if you've got your focus badly set you may well

find that you've got 0.4 dots now the purpose of the top line with those

dashes on it there's nothing to do with sizing the dots that's all to do with

assessing what power we're going to use to do the picture and that will become

obvious as we do the next test later on now this bitmap pattern will be

available on the Thinklaser website but you'll have to put your own

parameters to it and what I suggest you do is to run this at fairly low values

first of all I would set the speed at about 50 millimeters a second we've

talked quite a bit about high frequency impact engraving and how there is this

strange pre ionization zone on your tube before it really kicks in and starts

developing power most engraving really needs to be done at low power and this

particular zone up to on most tubes it could be 12 could be 14% you will need

to test your own tube to find out where the limit for that zone is and I would

stay inside that zone if you possibly can because you will get much better

results on both my machines I can safely say 11 or 12 percent stays inside that

zone so I'm going to set this to say 12 percent we need to make sure that we've

got none of this stuff here ticked we're just going to use standard x-swing but

bear in mind what I told you was that the size of these dots is 0.1

millimeters therefore that's what we're going to be using for a pitch 0.1

so let's go and have a look at the results that we got right we're

gonna check out the test pattern for our 2 inch focal length lens now the first

thing we did was to set the gap underneath the nozzle to 6 millimeters

and here's what we got now our first two lines at the bottom here ah hmm

well they're not really two lines are they they're a bit of a blur you

certainly can't see any dots so let's move to six point five and all of a

sudden we can see some dots that's half a millimeter difference in the focus

makes a significant difference so let's step up to seven millimeters and here we

are we can see definite dots now please excuse me I've got no idea what these

funny s-shaped things are here they're supposed to be single pixels like the

line above but they're not and my suspicion is that I've got two pixels

overlaid on top of each other and I've got a scan left and a scan right which

is shown up there so I'm gonna have to go and check my pixel pattern out before

I release it to you guys it doesn't make any difference because what we're trying

to establish is the quality of the dots on those bottom two lines and if I show

you the seven millimeter at the bottom here and the 7.5 at the top they're

fairly similar but if you look closely at the 7.5 ones and compare them to the

7 millimeter ones you'll find that the 7.5 are slightly bigger dots you know

it's only a very slight subtle difference but that's what you're

looking for there's only half a millimeter difference in these focal

distances and that is obviously quite critical even on a 2-inch lens which is

what we've got in here where the focal depth is supposed to be more tolerant

this demonstrates just how critical you need to be with your settings so we're

going to settle with the 7 millimeter and we'll concentrate on that now

because what we've got to do is to establish the size of the dot what from

that pattern yeah well it's not too bad because remember I described to you that

here we've got these little black dots and they're definitely all touching

there's no gap gap gap so if you had a dot gap gap then you could say well I've

got point 1 dots that was the pitch of those along the bottom line there and we

can confirm that we've actually got point 2 dots because remember what I

said about the second pattern up if we get a dot a space a dot a space and

those dots and spaces look approximately the same then we've got point two dots

well we've got two important pieces of information off that test this is

critical knowing what the dot size is and the second thing is to make sure you

get the focus set dead right because if you don't get the focus dead right then

you'll finish up with the dot that's even bigger than that so what we tried

to do when we look down this pattern here is to find the smallest crispest

dots and that tells us where the correct focus point is now before we move off of

our focal distance here I will just mention again something that I nearly

forgot and that is the fact that in addition to a two inch lens this machine

is also supplied with a two and a half and a 4 inch lens now I would honestly

suggest you do not try and use either of those lenses for this sort of work

now the only time you'd want to probably use something like that is if you're a

little bit on the I won't say desperate side but there's no other solution is if

you've got an object like this that you're trying to engrave a picture onto

and it's got a curved surface you'll need to make sure that as you scan

backwards and forwards along that curved surface you don't get too much change in

the quality of the picture and a 4-inch lens has got a much longer a depth of

focus on it so yeah it may have a use it will also be a much coarser picture now

I'm using the word coarse there but what I really mean there's less pixels per

inch because the dot size will be bigger

every picture has got an inherent resolution in it if it's a bitmap or a

photograph and if you check out what that is it will always tell you that it

is pixels per inch PPI now this machine and we've already started doing it works

in millimeters if we look over here we've already decided that the dot size

is 0.2 of a millimeter so somewhere along the way we've got to

define what resolution we can use that point 2.dot for, so there are twenty five point

four millimeters in one inch okay now these are pixels per inch so there is

twenty five point four millimeters now if we divide that twenty five point four

by 0.2

which is the size of our pixel dot we've got to make sure that our pixel is the

same size as our dot and that will give us an answer of 127

pixels per inch so that's the resolution of the picture

that we can work with anything more than that resolution and our dots will start

to overlap and if we overlap the dots you remember we're going to finish up

with double burns here we've got a picture at 127 dots per inch and if we

draw a pattern and we've got the correct ratio of black

to white in that set of pixels so here we've got some dots at 300 pixels per

inch and of course what happens if I've got my point two dots and what will

happen is the point two dots will do that and all the gaps that you'd planned

to have will disappear and all these will overlap and double burn so you know

this is going to be a complete mess so I urge you do not mess with this number

that's what the equation says you should use use it so let's go and have a look

now putting our picture into RDWorks and setting this magic number okay so

there's my picture imported into RDWorks and you'll recognize this picture

is something that we have used before I'm going to put the bitmap handle around

it and just take a look at what its properties are so at the moment it

clearly tells me at the top here at 600 pixels per inch which is fine now while

I'm in here I'm going to put these to zero just put some new handles around

that and up here we can see that we've got a picture size of a hundred and one

millimeters now I've already put the padlock on so that the proportions

remain the same because I want the horizontal dimension to go up to a4 size

which is 297 and there we go now if I put the bitmap handle on again you will

see something else has happened it was 600 pixels per inch remember well we've

now changed the size of the picture and an RDWorks has actually rescaled it for

us to a different resolution now remember just a few moments ago we

established at the best resolution that we could ever work with was 127 pixels

per inch well first of all just make sure that these two are set to 0

forget the invert we're not going to be using a mineral material we're going to be using

an organic material we're going to set the output resolution to what we found

we had to set it to 127 pixels per inch okay so we can say apply to

view but now what we're going to do we are going to dither the picture and we're going

to dither the picture with dot graphics and now we shall say apply to view and

there we go we can see we've got all sorts of dots in there and now we've got

this in dot form we can see how the picture is going to change now this is

where you need some skill some experience some luck because you've got

to basically distort this picture slightly to get a good quality result

onto your page it won't come out quite like this so what we're going to do is

we're gonna take the brightness up to start with because almost certainly we

shall need a brighter picture but go up in five percent steps or there abouts

4.2 and apply to view not much difference let's have ten percent well

you can see that we're bringing in some of the hairs in the background here

we're getting a bit more of the background coming forward but it's a

little bit washed out so we need to crisp it up with contrast so again we'll

go up in five percent steps apply to view five percent step again

ten percent

and maybe one more 15% now this piece of software is very very limited in its

ability to play with the picture and sometimes you need to work on this

picture in a piece of external software before you bring it in

but I'm not going to do that today we're going to stay here we'll try and make

the best of a bad job here so let's take the the brightness up again I don't

think we can get a great deal better than that we've got quite a crisp eye

there as you can see this eye is not bad either so we can apply that to the view

which we've already done and then we'll apply it to the source we need to click

on here and there we go so you see that picture now tends to pop out at you it's

got more brightness in it and we can see more of these hairs in the background if

you were going to put this picture onto acrylic or some mineral material what

you would do you would go back into the bitmap handle once you're happy with the

picture and you can see it on your screen looking good you can go back in

there and you could you cannot any longer play with the contrast and the

brightness they're fixed you could possibly reset the resolution if you

wanted to but we're not going to but you do get the opportunity to go back and

invert apply to view and there we go now there is absolutely no way that you'd be

able to work on this picture in a negative form unless you've got some

sort of perverted brain so you don't actually convert to an inverted form

until the very last minute so now and we've got to set the parameters well we

know that it's going to be a scan and we're not going to be blowing we'll try

11% and see what happens now we want nothing ticked down here at all we're

going to leave it with X swing which means it's going to scan in both

directions and this time the interval we know what the interval is

because we determined that when we said the dot size was naught point two of a

millimeter so that's what we set the resolution

into the picture to one to seven which is equivalent to point two so we know

what the interval is the only thing that we don't know at the moment is what

speed we're going to run at and this is quite a critical factor this is one of

the secrets that I have discovered I know from work that I've recently done

that it takes three milliseconds or somewhere in that sort of region for a

single pixel to reach its full power now if you want to push the power up to 20

30 40 50 percent it may well take longer but I know that when we're using dots

we're working right down at very low powers and at low power 3 milliseconds

is an adequate amount of time to allow a single pixel to form properly the next

thing is we've already determined that our dot size is 0.2 of a

millimeter so there's 1 millimeter and therefore we have 5 pixels in every

millimeter now that's quite important because we're now going to take 3

milliseconds for a pixel to form times 5 pixels per millimeter and the net result

is it's going to take 15 milliseconds for a millimetres worth of pixels the

speed of the machine is set as millimeters per second and so therefore

if we take one second and one second is equivalent to a thousand milliseconds

and we take that thousand milliseconds and we find out how many 15 milli second

intervals or how many millimeters there are what it amounts to is 67 and so we

set the speed to 67 millimeters per second so we now go in and do that and

we set the speed to 67 that's not something we can change

okay so there's all the parameters set we should now save this and go back to

the machine I've got my head set down at the bottom right hand corner if you

remember and so we'll just set the origin there and do a frame check

now this is going to take a long time to do so

we should come back and see it

and there we go I think you can probably see the effectiveness of the cross flow

there you can see the smoke being drawn away

if you look very closely you can see dots but when we pull away

I think he'll agree that's a pretty good photo rendition

now that's what you can expect by being careful but doing it slowly

I also think you'll see there's a significant improvement between what we

were trying to do about six weeks ago

and that there is no comparison I was scrabbling

around in the dark when I was doing that

that took about 40 minutes to produce that picture

and I'm sure you'll agree it's been worth it we can see all sorts of detail

on the hairs out here you can see all these little teeny-weeny hairs on his

beard down here we can even see these rings

you know there is a huge amount of detail in there that was not evident on

the original when we first looked at it look we can see the sword in the

background that's been pulled out so now I'm just going to remove the 2-inch lens

and replace it with a one and a half inch lens

there's our 2" lens and this was a 4" lens where I've taken the lens

the 4" lens out of the back of the tube and in the front of the tube here

I've put an O ring and I've modified the inside of the nozzle itself now that

allows me to pop a smaller this is normally a 20 millimeter lens system

here I've got an 18 millimeter diameter one and a half inch focal length lens

now we always put it flat side down and on top of that I'll put a small

compression tube and by the time I screw that in there against the o-ring

it's completely solid just very lightly clamped okay so now we've got a 1.5

inch length in here but I stress again this is not something that's standard

and available from Thinklaser this is something that I've designed and made

myself we're going to use the same paper but we've got to go through exactly the

same exercise because we've changed the focal lengths and we don't know what

size the dot is that we're going to produce and we don't know exactly what

the focal length is so we need to prove it while we're here at the moment what I

want to do is just point out to you the fact that I have got a mild steel plate

sitting on top of the bars and this mild sheet steel sheet is approximately level

with the frame of the page there's a good reason why I like using this steel

plate first of all as you can see I can put magnets on it

secondly it does not allow the air to pass down through it it blocks off the

air that would normally pass through either the bars or the honeycomb table

that you have on the top here and in this particular instance what will

happen is the air passes across the top of the table like this to those holes at

the back there now that produce a cross flow which is

absolutely essential in my opinion when you are engraving because you don't want

the air to go that I mean let's face it if this is the size of the picture and

that's the size of the open area around it there's more open area than there is

picture so what will happen is you'll get most of your air just disappearing

straight down there and it have no cleaning or purging effects on the top

surface of this this graphic that we're going to work with so I always make sure

that I get a cross flow a very high speed cross flow to pull the fumes

backwards and the other thing that I do and I

mentioned it before is that we set the set the graphic start point down here so

that when we engrave we shall be engraving backwards and forwards like

this in gradually moving towards the back of the machine and that means that

all the smoke that's generated during the engraving process is being pulled

backwards now it tends to come up in the air before it goes backwards so very

little of it as ever going to reach this clean paper here but just in case it

does by going backwards it means that we're going to not get any of that

debris painting our picture we're going to leave the picture that we're

producing in a nice clean smoke-free environment now this steel plate is not

something that is standard on the Thinklaser machine you're gonna have to make

this for yourself don't get any plated material just plain raw mild steel if it

goes a little bit rusty or a little bit messy picking up fumes and condensation

particularly if you're doing MDF you can get horrible Brown mucky stuff on the

surface there so acetone will clean it off and if it goes rusty then all you

need is an industrial cleaning pad and this abrasive pad will keep your table

nice and clean so we think this is seven and a half mil

so what I'm going to do I'm going to start eight and a half and we'll work

our way for a millimeter above and a millimeter below the ideal setting point

now I will inspect these mmm and then we can look at them under the microscope

there's better separation between 7:00 than there is between the 7.5

so in fact I'm going to award that one

the prize seven millimetre and now we're going to

estimate the dot size now this is going to be interesting

that's my estimate for that one 0.15 so they're slightly

smaller which means we've got to go back and we've got to revise the picture

because we've got to reset the pixels per inch we could run the same picture

but I don't want to do that because the rules are the rules

so I've redrawn the picture so that it's got an interval 0.15 and a resolution of

170 pixels per inch now what we got to do is calculate the speed which I can

modify here on the machine the key thing is three milliseconds is the time that

we're working with for a single dot this time we've got one millimeter and in one

millimeter we're going to divide that by 0.15 and that equals 6.7 pixels per

millimeter we've got this magic number of three milliseconds that applies

regardless of the number of pixels per inch that's just a fixed constant

consequently we're gonna have to multiply the three milliseconds

by the number of pixels per millimeter so that tells us it's going to take 20

milliseconds to do a millimeters worth of pixels remember our speed as

millimeters per second so in one second we have a thousand milliseconds and

we're going to divide that thousand milliseconds by 20 that's going to

generate a speed of 50 millimeters a second higher resolution lower speed so

we've now got to set the speed to 50 millimeters a second because we've

reduced the speed the chances are that we shall probably have to reduce the

power as well at the moment the power is set to 12% so now we've got to go back

to our test pattern again

now I'm sure it's pretty obvious to you that 10% is so much lighter than the 11%

there's a huge difference there between those two but there isn't a huge

difference between 11 12 and 13 in terms of color but there probably is in terms

of depth of pixel so what we've got to do now is very carefully look to see

whether or not we're going to use 11 or 12 now that's one of the reasons why

when we look at this pattern you'll see there's a load of bars across the top

they are multiple pixels and they will help us to decide whether or not we

should choose 11 or 12 is 12 burning too deep relative to a single pixel or is 11

a more balanced view between one pixel and a group of pixels and that's an

assessment that we've got to try and make

but I think I'm gonna settle on 12%

because 13% the dots are getting just a little bit bigger the color difference

is not huge so I think we'll settle on 12%

so 12% and 50 millimeters a second those are the settings

we were very pleased with the quality of picture produced by the two-inch lens

let me show you what happens with a one and a half inches

it's quite staggering I have to say I did not think it would be as big a

difference as that now part of the advantage of this is the fact it's got a

deeper color to it and when you think about it the reason for the deeper color

is because although I've reduced the power very slightly

the energy density in the lens is twice as much as it is in this lens so I've

got a much sharper hit but look at the clarity of some of this stuff down here

this is the same picture by the way I haven't messed with the tonal range of

the picture it's exactly the same picture as this one the only difference

is the fact that it's done with the 2-inch lens and probably the the color

difference between the two is because we've got a higher power density in each

one of these dots okay so I was slightly wrong again there

is a big difference between a one and a half inch and a 2 inch lens

but the whole purpose of today's project was to demonstrate that there is a

formula that you can follow to get a good quality photo engraving I'm

extremely pleased at the results we got today the 2-inch lens was exactly what I

expected it to be it was a good quality rendition of the original but when we

compare it to the one and a half inch lens where we get a really good deep

contrasting picture because we're able to get a much deeper burn it does show

you the value of having the right material in the background and the right

concentration of energy I think we've got much higher energy densities here

that's able to produce this burn without actually etching away the material if

you start overlapping your dots you get a 3d feel to your picture and there are

no 3d feels to either of these pictures so I know that my dot quality is good

these are exactly the same picture these are exactly the same cards these are

done as it happens and exactly the same power this one was done at 12% this one

was done at 12% I think this one was done at 67 millimeters a second and this

one was done at 50 millimeters a second this is lower energy density and faster

which maybe accounts for why it's slightly more washed out now I'm not

trying to put Thinklaser into a tight corner or anything like that but I think

that you can see from these results that the difference between the 2" lens

and the 1.5" inch lens which is not available as standard is

quite staggeringly different now without anything to compare it with this is

still quite a nice photograph but this one here is something a bit special this

is almost a perfect sepia photograph so we've succeeded in our aim there is a

formula which will guarantee that you get almost the perfect photo engraving I

think that in a future session we ought to take this a little bit further and go

into mineral materials such as glass slate and maybe into plastics like

acrylic which are things that people tend to use a lot of so whether we use the

same picture which might be a good comparison to see just how we get on

with this picture within different materials we'll have to see but thank

you very much for your time today and I'll see you in the next session

North Korea Continues Work on Second Barge Used for SLBM Testing - Duration: 0:40.

Pyongyang is reportedly continuing work on a second barge for testing submarine-launched

ballistic missiles.

That's according to U.S.-based North Korea monitoring website 38 North.

Commercial satellite images of the Nampo Navy Shipyard on North Korea's west coast taken

on September 1st and 21st... shows the regime could be attempting to do one or more of several

things: developing a ballistic missile for the West Sea...; salvaging barge parts; or

studying the barge so it can build its own in future.

Various aspects of SLBM designs can be tested using such a facility, the first one played

a key role in developing the Pukguksong-1.

FOA Webinar: Reducing Overscreening for Breast, Cervical, and Colorectal Cancers among Older Adults - Duration: 36:09.

>>Hello everyone. Thank you for joining us today for the Funding Opportunity Announcement

Webinar: Linking the Provider Recommendations to Adolescent HPV Vaccine Uptake. Before passing

the presentation over to our speaker Dr. Sarah Kobrin, I would like to give you a few tips

for getting the most out of today's webinar. All attendees will be in listen mode only.

Please feel free to submit your questions throughout the presentation in the Q&A panel.

We will ask them on your behalf during the Q&A portion of the webinar. If you need closed

captioning, please refer to the Media Viewer panel. Today's webinar is being recorded and

will be posted online at a later date. We have a feedback survey as well, please take

a moment to complete that at the end of today�s webinar. With that I will pass the presentation

over to our speaker. >> Good afternoon everyone. My name is Sarah

Kobrin. Thank you for your interest in making time today to hear more about the announcement.

For those that are more experience, forgive me doing a bit of an overview about the program.

Sponsoring this research interest in HPV vaccine. And how NIH funding works for people who are

less familiar. >> This is a helpful slide about the WebEx

logistics as mentioned. You can ask Jennifer if you have any questions.

>> A moment about myself, I know many of you since I�ve seen the list. My name is Sarah

Kobrin acting chief of the health system and interventions research branch here at NCI.

Part of the healthcare delivery research program. In our branch, we are very interested in the

kind of multilevel understanding system context approaches to prevention and control intervention.

As an outline for the talk I will give you some background. More details about the FOA

itself. And the primary focus will be a chance to ask questions. And to hear the answers.

>> This is a very simple schematic of our division organizational structure. NCI has

several different divisions. We are extramarital division, working with investigators like

yourselves around the country. Called the Division of Cancer Control and Population

Sciences. We have several different programs within the division. I work in the healthcare

delivery research program. >> Within that program we have three different

branches. The one that I sent is in the middle of the schematic is health systems and interventions.

I have colleagues who studied outcomes, another type of relevant outcomes, as well as healthcare

assessment branch, which holds Medicaid database and study of other types of care delivery

processes. >> The next few slides are information relevant

to all of the NIH funded research. Not specific to this announcement but to give an overview.

It is true that most of what NIH funds is investigator-initiated grants. For those who

are familiar with parent mechanisms, those came into being because once we went through

electronic, there was a box that needed to be filled in with type of name of an announcement.

Most people use that parent announcement so they can bring in their own ideas, not something

that we have called for. As a specific area of interest. We also publish announcements

of different kinds, and different funding opportunity announcements, which is a generic.

And these are three of the major distinctions among them. RFA stands for request for applications.

That is the only one of these three where money is set aside. The three share the fact

they are authored by someone inside the Institute who identified the area of research and goes

through a multi-level and elaborate process of approvals within the Institute to publish

this as an area of interest. The distinction for the RFA, along with the approval to publish

interest is the commitment to spend a certain amount of money under the application that

come in. They have generally a single receipt date. Sometimes a repeating one or a one-shot

opportunity. And they are always reviewed by a separate scientific review group. Not

one of the standing panels that most of NIH applications are reviewed by.

>> And they we have to a different type of PA, program announcements, and a PAR. Both

of these are without money set aside but do have the endorsement of the Institute leadership

as an area of science we wish to promote. A regular program announcement usually has

three receipt dates in a year. And is approve for a three-year period. Once it is open,

it is open for all those receipt dates for 3 years. The difference between PA and PAR

which is the R, which can stand for several different things. It can be a special receipt

date. You may not use ordinary receipt dates in one year. It could be a separate referral

process and a separate review. In this case, the announcement we are talking about is a

PAR. Meaning no money is set aside for it. The priority area is endorsed by the Institute

and there is a separate panel coming together to review the announcement.

>> Also relevant to the current announcement, there are three different levels or mechanisms

of research projects that people submit applications for funding.

>> The smallest one is that R03. The R03 and the R21 share a two-year period. But the R21

has more money. And the R01, or the research project grants, is the main type of grant

we fund. And they differ in scope, in terms of years that can be funded, the amount of

money funded, and several important other differences. In order to do an R01, it is

necessary that you have pilot data in place and a circumscribed research project well

justified by existing data by an experience investigators or team. The R21 is a two-year

period. It is often for new exploratory development of types of projects. And I will talk about

how each mechanism applies or plays out in relation to this HPV vaccine announcement.

>> The smallest is the R03 and can also be 2 years. It is less money and not considered

to be something for that is very experimental or very innovative. It is required to be different

from what others have done. It does not have to be risky. R21 are often considered risky

and R03 is a great mechanism for collecting the preliminary data in order to submit an

R01. People also develop measurements or conceptual modules that define projects with the R03.

>> Now I will speak to you specifically about this particular funding opportunity. I am

sure that you have signed on because you are interested in the topic and promotion of the

HPV vaccine. And there is a lot of evidence of a provider�s recommendation. And it is

a central component to successful uptake. The purpose of this PAR is to place that provider

recommendation into the healthcare delivery context and to understand how the delivery

system either enhances or inhibits the effectiveness of that recommendation. Not strictly speaking

a study of the provider recommendations itself but how that recommendation is in the context

of the delivery system. So, the characteristics of the provider, the parent patient or both,

and the clinical setting. Those are the kinds of contextual variables that we are interested

in understanding. And how the effect whether the provider makes a recommendation and whether

that recommendation results in the uptake of the vaccine.

>> My view is that to do this kind of work, expertise is needed and cancer prevention

and control in both adult and childhood behavior. Immunization promotion and healthcare delivery.

And because those areas of expertise are so diverse, and not commonly found in another

type of behaviors, that are promoted in care and reviewed routinely by NIH with their standing

studies. This announcements has its own separate review panel to bring together the needed

expertise. >> The three types of studies on this slide

map approximately three different mechanisms described earlier. The first is to identify

characteristics, provider characteristic, the parent or patient practice level. The

same three levels being mentioned across the announcement. The focus here is on the identifying

characteristics and that is the type of project that might be done with a smaller R03 mechanism

for example. >> The second type of study is to identify

mechanism, unfortunately that is a different use of the word mechanisms. This is mechanisms

on the causal sense by which these characteristics identified operate to enhance or inhibit uptake.

A more sophisticated conceptual model might be a risky effort that R21 could fund.

>> And the third type of study is developing and test interventions. To increase vaccine

uptake by targeting identified characteristics at two or more of these levels. The R01, R03,

R21 labels don�t appear in here, because any one of them might fit to a different mechanism

in the grant sense. It is a rough guideline for how they fit.

>> The components of this announcement are focused on essential to writing and perhaps

reviewing applications and interest in funding an application that is responsive to this

announcement. They should have all characteristics and key elements.

>> Primary data needs to be collected in a clinical setting where HPV vaccine is being

both recommended and administered. There is a context around the recommendation that it

can take place and come to the point of vaccine administration. Because we have very strong

interest in improving public health in the U. S., and primary recommendation by the vaccine,

for boys and girls. Many proposal to focus on both, unless there is some compelling scientific

or reason. The reviewer will decide what is compelling. For excluding one of the groups.

>> Similarly, because particularly at the time we were writing this we wanted to focus

on public health -- even though this is a research announcement to promote public health

directly in the United States. We wanted to focus on closing the disparities of the HPV

vaccine. As you know, in this particular behavior, and disparities that are similarly expected.

And for other kinds of healthcare delivery services, have turned out to be different.

Populations may have lower access to other things have tended to have higher access to

the HPV vaccine. The point is not to define how this vaccine disparity is compared to

others, but how these applications must focus on populations where vaccine uptake is lower

than the national average. Finally and perhaps the most integral to the health announcement

from a scientific perspective, necessary to consider and measure characteristics of all

three levels. That is to say the provider is one level, patient parent as a combined

level and practice. >> Some details on this slide, information

specific to the announcements, and some good practice for any time you are applying for

NIH funding. Read the announcement carefully. And even though the meat of it is in one section.

Section two and four are the places with the most details unique to an application are

included. It is true every single detail is relevant. Relevant to all NIH grant applicants.

>> These announcement. The first submissions were September of last year, exactly one year

ago. As I said before the standard submission dates apply. All three regular dates and the

three years open for -- if you look up for NIH submission dates it follows the regular

dates. >> There is no letter of intent that is due.

If interested in how soon you can start your research after you submit your application,

you can find the standard dates for NIH as well. Do we have a link? Or could we add a

link to NIH standard dates? I am not sure if we have it on here.

>> Currently the announcement is scheduled to expire July 2019. Whether an actual end,

or starting one year from now. Working on having it renewed depends on how many people

apply in work is being done. >> As with any NIH application, start early

and allow yourself time for getting into the system and mistakes that come through the

system. And the final application to be approved and received before that end date.

>> This is information to contact me. I know many of you have contacted me. We are going

to be posting the webinar and FAQ. Jennifer mentioned it will be recorded. You will hear

questions and answers to come. We will take that group of questions and answers to put

them on the website. >> Here is a promotion for our social media

presence. Stay connected with us. I am looking forward to hearing your questions.

>> Okay any questions? >> The first question that came in, I will

read and answer it, if you are proposing to assess the effectiveness of an intervention

that is aimed at two levels? The provider and the practice setting, is that acceptable

for this FOA? >> The answer is for both R21 and the R01

it is necessary conceptualize and measure all three levels. It is not necessary to intervene

at all three levels. If you are interested in intervening at two levels you need to have

both baseline and outcome measures reflecting your understanding how the different levels

influence each other. It could be interaction or mediation or different analytical ways

to think about it. But you should be conceptualized how for example the provider and practice.

If you are intervening with the provider and make a change on the provider. How will it

affect the routine of the nurses? To give shots after five minutes? Or changing something

that has an impact at the practice level as well. It is not okay to do one from column

A or column B or column C. >> Another question is whether older teens

and younger adults can be included? The answer is they can but the primary focus still needs

to be on the 11 and 12-year-olds. If it makes sense within a clinical setting, to be vaccinating

everyone eligible is fine as long as you have the power and focus on the 11 and 12-year-olds.

>> Someone asked about the special review panel. Rather than one of the standing study

sections that exist for CSR, the Center for Scientific Review, a separate panel managed

by CSR is put together for every one of these reviews. Bringing together expertise that

is necessary for understanding changing kids and adult behavior in healthcare setting.

And measuring healtchare delivery as well as individual levels. There is a separate

panel that reviews these every time. And I have the opportunity to talk with that panel.

In a conversation like this one. So they understand the intention before they review the application.

>> Another question is whether secondary data can be used? In the text of the announcement

it does say, as I mentioned to you earlier, it is necessary to collect primary data in

a clinical setting. It is possible to use secondary data for the purposes of identifying

the population who have lower uptake. It�s necessary that you have to do primary data

collection to identify the group. The main focus of the research needs to include primary

data collection. >> Another question. Is it okay to include

nine and 10-year-olds? Yes the answer is the same. The recommendation for the vaccine begins

as early as nine. There are clinical settings in the U. S. beginning vaccine recommendations

as age 9 as routine practice. That is fine but the main focus needs to be 11 and 12-year-olds

as that is what the national recommendation is.

>> Another question is whether the delivery setting has to be able to document low uptake?

The simple answer is yes. The more complicated answer is there are different ways of getting

it. Secondary data that is available to show that I may be in extrapolation from state

or county level data. There needs to be good faith effort towards identifying that this

particular population has lower uptake. And of course it will be the reviewer who decides

it that argument is made convincingly. >> We have a lot of questions about funding

-- how does funding work for PAR? Most of NIH funds is what we call investigator initiated.

Even though it is in response to a call for our particular scientific area of interest.

Funded through the same research project pool of money that NIH has to spend on research

funding every year. There is not money set aside. But there is an enormous fund.

>> One question what does an early investigator and first-time R01 do on a scoring process?

A first time investigator or new investigator is someone who has not successfully competed

for R01 level award in the past. Both very important. Successfully means you can submit

and not be funded 10 times. Which of course we do not want. If it happens you cannot lose

your new investigator status until you have successfully competed. That you are no longer

a new investigator. You receive your first R01, then you are not. The competed part is

also important. A person is getting the role of PI for the project. If they have never

before successfully competed, it is still a new investigator. You might be in the role

of PI for R01 that someone else competed for and it does not change or new investigator

status when you apply for one yourself. >> Whether you need to request a special review

panel? No you need to identify you are submitting in response to this PAR. And then you will

be assigned. A word to the wise, when you have submitted and you see where it has been

assigned, double check that CSR did not make a mistake and send it to a different review

panel. We do that before every review. Check submissions to make sure nothing went awry.

It would be helpful for you to be part of that quality chain.

>> The special review panel does not have a separate name. You do not need to know that.

You do not need to request it. It is just the special emphasis panel put together for

this PAR. >> When you look where you have been assigned,

it should say the name of the PAR for review. >> Is it necessary to address completion of

the vaccine series? The answer is no. If you have the time, and that is the type of intervention

you are prepared to do, by all means. But the focus of the announcements let you decide.

>> How broadly is primary care provider defined? I think what I said earlier, you need to be

in a context where someone can make a recommendation and that person or other people can deliver

the vaccine. Presumably that is mostly pediatricians or family doctors. I am less interested in

defining primary care providers than in primary care providers who can both make the recommendation

and in the same context in delivering the vaccine.

>> Is there a preference in the PAR for proposals that include two or more delivery systems

over one? No. In the long answer is it would be very hard within a regular R01 budget to

be looking at two different delivery system. In hypothesizing about the differences between

them. If you can by all but that is not the expectation.

>> There is a question that I am unsure about. It�s about percentile. Do they compete with

other grants for different PAR and investigator initiated calls? Short answer is yes. As I

said there is one very large budget at NIH for all of the non-RFA funding opportunities.

Yes is the answer because money is not that aside. One thing to know, R03 is not percentile.

None of these proposal are percentile. Because they are being reviewed with the standing

study section they get compared to � hold on -- I may have said the wrong thing. They

are in fact percentile in compassion to CSR all. Meaning everything that gets reviewed

though all the standing study sections in CSR, the scores of proposals reviewed under

this PAR get compared to that whole list in order to have percentile developed.

>> But R03 do not get percentile. >> A question about the appropriateness of

the investigator who has clinical expertise with HPV related cancers. And quality improvement

but no published manuscripts on the vaccine. Would it be better to submit a R21 than an

R03? First of all it is good to see you understand that if you do not have preliminary data you

would not be thinking about R01. >> In choosing between an R21 and R03, I think

you are much better guided not by your own experience but by the nature of the research

want to do. Is it a small project? Like developing a new set of measures for a particular population?

Collecting preliminary data for developing an intervention later? Those might be more

appropriate for R03. And R21 if you have something a bit riskier. Beginning to understand the

mechanism by which the different characteristics of the setting influence each other. That

requires collection of more data. That is more risky in the sense that nothing positive

will be learned. Again it is about the research you want to do, and the cost between R03 and

R01 and the maximum budget. >> If you want to work in a state, where vaccine

uptake is high? And the interest is in identifying a vulnerable population or a population with

low vaccine uptake. There is nothing about this announcement that makes it specific to

a state. The national immunization survey are reported by state. But there are many

other sources of local information about vaccine uptake. There is no necessity to choose a

state to work in where vaccine is low across the state. There is a necessity to identify

the population where vaccine uptake is low. >> Whether applicants who have not had prior

NIH funding before encourage to apply? The answer is yes. Different kinds of questions

can be answered. More or less experience with working in an area certainly enthusiastically

encourage to apply. You can talk to me to find out the best fit and resources available

to you in your own expertise and team. >> I do not see any more questions. Given

that I will think everyone very much for taking time today. The questions and answers will

be typed up in a more formal and practiced way. We

will be putting thank you's on

the website. You

are welcome to contact me. And

I hope that

you will apply. It is an important problem. Thank you

for your time. This is

the

end

of today's webinar. Goodbye.

Case: VR Experience for the Dutch Fire Department - Duration: 1:58.

We are Warp Industries and we develop VR training courses for companies to train their employees

For example Safety and Security training courses

and what do you when their is fire on an oil rig

but also leadership, retail and medical training

The only thing you need is a smart phone and VR goggles.

You can train when where and where-ever you want.

and that flexibility will save you a lot of money, planning and resources

and because we use 360 video

the training is super realistic

For the Fire Department we created three scenarios for a live safe campaign

In the first scenario you have to make sure your house is save before going to bed.

In the second scenario you have to know what to do when you have to escape during an emergency.

And in the third scenario you have to act during a kitchen fire

and all these scenarios are available in both app stores

How does a scenario come to life?

We start off with a brainstorm session with the customer

Here we combine our VR knowledge with the learning objectives and protocols of the experts

Next is the filming, which usually takes a day.

We use 360 video and actors

Lastly we combine all elements in an app so everyone with a smartphone can play

The experience is highly appreciated by people of basically any age.

Ranging from five and six year old kids to senior citizens

Everyone is enthusiastic and they all want to play the VR experience again at home.

and, very important, to pass on the message

Very cool experience, and confronted me with the different scenarios that can play out

and that only one mistake can lead to very dangerous situations

Interesting to see how a situation really is, which you normally don't experience

Your house isn't on fire every week...

Security Awareness: Important for all Businesses - Duration: 1:58.

We're a small business.

Why would any hacker be interested in our website?

Hackers don't care who you are Or what you do

Every business has data of value to hackers somewhere.

Emails and passwords, sensitive customer and supplier information

Data they can sell or hold hostage for ransom. And while a few big attacks make news,

it's in smaller businesses that cyber attacks are soaring.

Hackers use your own information to impersonate you.

Your profile and connections on LinkedIn. The school where you graduated.

On Facebook, they can see you're married, have kids,

and went on a vacation to Yosemite. They have everything they need to make an

email seem real And face it: You're at work.

You're busy, you're distracted, And that email looks authentic,

You click.

Most security awareness training fails because it doesn't change a person's behavior.

And smaller organizations start from a false sense of security as it is.

For awareness to become second nature, vigilance and alertness to threats must be ever-present.

Ingrained.

A mental default It took over a decade for the routine use

of seat belts to become a social norm!

And how did that happen?

A steady, educational drumbeat spread over an extended period of time.

It takes long-term effort for people to form new habits….and people are the first line

of defense against today's security threats.

Drive your risk closer to zero with Summit's Security Awareness Service.

It's habit forming.
