They had been making ritonavir for two years. They knew its exact chemical composition and every part of the process used to make it, so they check all the input ingredients again, all the settings, every temperature setting and procedure.
“Crystalline” means the atoms are arranged in one of six orderly patterns called crystal systems. Having a “specific chemical composition ” means it can be described with a particular recipe of chemical elements. And “formed by geological processes” means it’s cooked up in nature.
So we are born of the ocean. Each of us has about 98% similar chemical composition of blood similar to seawater. The amniotic fluid in which a fetus develops is about 99% similar to seawater.
They’re all over the planet! And mineralogists — geologists who specialize in minerals — identify them by their chemical composition and physical properties. But sometimes this takes quite a bit of… investigation.
It just depends how thick the clouds are whether you keep observing through the clouds or you have to stop because there's just nothing coming And it confirms that the whole story I have told you about the chemical composition and they're telling us that we can look back in time
I’m about to say a lot of words. A mineral is an inorganic material with a solid, crystalline structure and a specific chemical composition formed by geological processes. An “inorganic material” is not made from the carbon molecules associated with living things.
And out of that formed the Moon. But what didn't make sense for a long time were the isotopic studies that we had in the chemical composition between the Moon and the Earth. Those are now coming into much clearer focus in terms of how hot the Earth was, how wet the Earth was, how big that body was, what kind of angle that body had
What we're really measuring is the structure of the density of stars as you get further away from the Galactic Center, and as you get further away Now, the three different histograms correspond to different assumptions about the exact chemical composition of the star, and that actually tweaks the color, absolute magnitude
that thing. And the Mercury was pretty much, as you probably are aware and many of you studied all this stuff was that Scott Carpenter had a lot of problems on his flight because sensing and now we can go to the Moon without landing and find out what the chemical composition of the surface is anywhere we want to look just doing it remotely. So that was one of
In geology, the word “rock” has a specific meaning: a solid cluster of one or more minerals. Minerals, by the way, are solid crystals with a specific chemical composition , formed by geological processes. Dwayne one of us is gonna have to change.
That color comes from a sparkling mineral called olivine. But the colors would start changing as we moved into the mantle transition zone — an area of increasing temperature and pressure that causes the chemical composition to shift. The deeper you go, the hotter and more densely packed the minerals are.
Let's get to the heart of the matter. So my work is often called stellar archaeology because we take these survivor stars that are in the Milky Way today, and we study their chemical composition so that we can their age, or at least their formation era, due to the small amounts of heavy elements in them.
Nothing about the context, the stratigraphic unit, I should say, of this artifact. But if you use your budget correctly and you get a few key samples, because, of course, what mass spec is doing is giving you the exact chemical composition .
that thing. And the Mercury was pretty much, as you probably are aware and many of you studied all this stuff was that Scott Carpenter had a lot of problems on his flight because the rocks we thought we'd see on the surface. So when Dave and Jim brought rocks back they did a chemical composition analysis and then they compared that with what we got from remote
that thing. And the Mercury was pretty much, as you probably are aware and many of you studied all this stuff was that Scott Carpenter had a lot of problems on his flight because atmosphere, we'll let you know." So they called me back a few hours later and said we figured out what it is." I said, "Oh, okay what is it?""Chemical composition it's urine."
