That equals uv.

Integration by parts. uv.

A CT scanner, UV lights.

live in high UV areas.

live in low UV areas.

the thickness of that varnish relative to that globe

We heard about the atmosphere as a thin layer of varnish.

So that's the uv term right there.

Look at some of the major latitudinal transgressions people from high UV areas going to low UV and vice versa.

If you had a big globe with a coat of varnish on it,

So the integration by parts just tells us that the integral of uv prime is equal to uv minus the integral of

Between 1520 and 1867, 12 million, 500 people were moved from high UV to low UV areas in the transatlantic slave trade.

So we have this integral of u prime v is going to be equal to this, uv minus the integral of uv prime.

There is a lot of varnish still sitting there, several retouches, and some over cleaning.

And we can still say, from 0 to infinity of uv prime.

Now, if we take the integral of both sides of this equation, we get uv is equal to the antiderivative of u prime v plus the antiderivative of uv prime.

The integral of u well, let's say uv prime, because that will match what we have up here better is equal to both functions without the derivitives, uv minus the integral of the opposite.

We've seen UV scales go off the charts, which are a known consequence of geoengineering, ozone destruction.

And now, we have uv prime, so u is minus 1 over s e to the minus st.

What's very, very important here is that the earliest humans evolved in high UV environments, in equatorial Africa.

However, this was a disadvantage in the more southern climates, where increased UV radiation led to cancer and decreased fertility.

Let's see, so the Laplace transform of t is equal to uv. u is t, v is this right here.

But the active irradiation, during the UV and for an hour after it, there is dilation of the blood vessels.

Now, if I were to integrate both sides, I get uv this should be review is equal to the integral of u prime v, with respect to dt but I'm just doing a little bit of shorthand now plus the integral of uv prime.

It's times minus 1 s, e to the minus st. e to the minus st, that's the uv term right there.

Or, maybe you've wondered how UV rays from the sun can actually cause skin cancer, unless you have mother nature's natural sunblock

So we put patients with these subjects under the UV, and their NO levels do go up, and their blood pressure goes down.

This is same as looking through earth's atmosphere that absorbs UV radiation through the ozone layer or in, infrared bands of molecular water absorption.

Now the really hot pink and red areas are those parts of the world that receive the highest amounts of UV during the year.

Madonna of the Chair that when just shining a UV light on it you suddenly see another, different lady, aged lady, I should rather say.

You know every season when we come to this farm, when somebody wants a can of beans, a little coffee, even some of this floor varnish for a Saturday night, they got to pay you double.

Then all of a sudden, I started worrying about photosynthesis and the pH balance, and the UV radiation, and all this different stuff that would make my jalapeños grow.

And when we shone UV at them, or when we warmed them up to the same level as the lamps, but didn't actually let the rays hit the skin, this didn't happen.

Space doesn't naturally have what we need to survive when we travel there no air, it's too hot or too cold, no ozone to protect us from those nasty UV rays, either.

let's make this what we want to solve for, so we can get the integral of uv prime is equal to we can just subtract this from that side of the equation, so it's equal I'm just swapping the sides, so I'm just solving for this, and to solve for this, I just subtract this from that, so it's equal to uv minus the integral of u prime v.

If we had UV eyes or X ray eyes, we would really see the dynamic and dramatic effects of our Sun's magnetic activity the kind of thing that happens on other stars as well.

Different amounts of UV hit different parts of the Earth at different times of year, so you can actually work out those stores of nitric oxide the nitrates, nitrites, nitrosothiols in the skin cleave to release NO.

And what we've shown is that doing a sham irradiation this is the thick line here this is shining UV on the arm so it warms up but keeping it covered so the rays don't hit the skin.

So this Laplace transform, which is this, is equal to uv, which is equal to e to the minus st, times v, f of t, minus the integral and, of course, we're going to have to evaluate this from 0 to infinity.

So this is going to be equal to uv. u, I'll use this t to the n, so u is t to the n, that's our u, times v, which is e let me write this down so it's minus there's a minus sign there, so we put the minus.

So when we want to learn whether a planet is habitable, whether it might be amenable to life, we want to know not only how much total light it receives and how warm it is, but we want to know about its space weather this high energy radiation, the UV and the X rays that are created by its star and that bathe it in this bath of high energy radiation.
