WHAT IT DOES

The term theoretical chemistry may be defined as the mathematical description of chemistry. The term computational chemistry is generally used when a mathematical method is sufficiently well developed that it can be automated for implementation on a computer. Note that the words exact and perfect do not appear in these definitions. Very few aspects of chemistry can be computed exactly, but almost every aspect of chemistry has been described in a qualitative or approximately quantitative computational scheme. The biggest mistake a computational chemist can make is to assume that any computed number is exact. However, just as not all spectra are perfectly resolved, often a qualitative or approximate computation can give useful insight into chemistry if the researcher understands what it does and does not predict.

This requirement should have been unnecessary since clause 4.2.1 requires the quality system to be maintained. However, what it does do is overcome any ambiguity by defining the occasions when the control plan has to be updated.

There is, then, the problem of determining for each discipline what it does in the way of diseovery and proof, what eriteria it uses for measuring the quality of its data, how strietly it can apply canons of evidence, and in general, of determining the route or pathway by whieh the discipline moves from its raw data through a longer or shorter proeess of interpretation to its conclusion . 

If you have a health and safety committee, you could list what it does, who is on it and how often it meets. 

The Environmental Protection Agency s Web site explains how acid rain forms, what it does to the environment, and ways we can all help reduce the presence of acid rain. 

There is no magic in the functions nyquist () or bode (). We could have done all our calculations using the more basic freqrespo function. What it does is essentially making the s=jco substitution numerically in a given transfer function G(s). A sample usage is... 

Usually, types are partial descriptions. They say, If you do X to one of my members, the resulting response will have this property and that property. But they don t always tell you everything there is to know about the outcome, and they don t tell you what will happen if you perform actions that aren t mentioned. This incompleteness is important, because it means that type specs can be easily combined or extended, essentially by and-ing them together. A type is quite different from a class in a programming language, which is a prescription telling the object how to do what it does. 

Specifications describe how a client can use a component. What we really want to say about a component is what it does its behavior, or the actions it takes part in. We have seen how to specify the externally visible behavior of a type by specifying actions in terms of a type model of attributes. Because the component doesn t necessarily have to be implemented along the same lines as its model, the implementation need not explicitly represent distinct objects that belong to the types used within that model. Those types are used to structure the static model and relate it to the business. 

In some cases, we are interested both in what an action achieves from beginning to end and also what it does while in operation For example ... 

Abstract diagrams are good for many purposes. At the whiteboard, you want to exhibit the main ideas of something without all the details of program code. Perhaps you want to say what it does and not how, or what it requires of other components that plug in to it. And whether it s a single procedure or an entire planetwide distributed system, you want to fit it all on one board and convey useful things about it. 

We describe an object s behavior using a type, with two parts to its specification the operation specifications (usually pre- and postconditions) defining what it does and the static model, providing the vocabulary of terms for the operation specs. 

The specification of a component goes hand-in-hand with the design for the process within which it is used. You cannot specify the component without having some idea of how it is going to be used you cannot define how it will be used, without knowing something about what it does. 

EDTA is called a chelate. Describe specifically what it does. You will need to explore other chapters to answer this question. 

What is a photomultiplier tube Describe what it does and how it works. 

UPS hires people that will fit into its culture and who will fit into this iterative improvement and measurement work place. Remember, the people that UPS avoids are those wanting a fast track to the top. UPS is looking for those who want to be part of a team that is the best at what it does and who love the blocking and tackling of business. The payoff for a job well done is the opportunity to... 

Some people may disagree with this success trait. I have noticed a strong correlation between high achievers and big sex drives. This does not mean that in order to make money you have to have lots of sex. (Although there might be a correlation to how much money you have to how many sexual offers you get ) What it does mean is... 

How a particular drug is able to achieve what it does to make one feel reheved (i.e., mode of action). 

It s like people think they re going to take a pill and it s a happy pill, and then they re going to be happy. And really what it does is it balances out feelings. But it s a fairytale if people think they re going to take a pill and then run out in the street and say, I m happy. .. . 

The word Principle in Chymistry must not be understood in too nice a sense for the substances which are so called, are only Principles in respect of us, and as we can advance no farther in the division of bodies but we well know that they may be still divided into abundance of other parts, which may more justly claim. .. the name of Principles wherefore such substances are to be understood by Chymical Principles, as are separated and divided, so far as we are capable of doing it by our weak imperfect powers. And because Chymistry is an Art that demonstrates what it does, it receives for fundamental only such things as are palpable and demonstrable. ... 

There are several ways of identifying whether a compound is an acid or a base, depending on what it does with protons and electrons pH and pOH calculations, along with the values of dissociation constants K and /CJ, can help chemists determine the properties of these acids and bases. 

Scope of the system what it includes and what it does not include... 

Another aside. There is a trivial, and fun, bit of nomenclature which I have used for years. I have, in my notes, referred to psilocybin as PSOP (because of the phosphate thing) and psilocin as PSOH (because of the exposed OH group). I have gotten into the habit of referring to the acetate as PSOA, the O-methyl ether as PSOM and the chemical intermediate O-benzyl ether as PSOB. I know that this will never catch on, but I still do it because it is convenient and a bit campy. One code that is not mine, but Sandoz s, is CMY for 1-methyl-psilocin. I know it has been looked at in a clinical environment, but I have not idea as to its activity. It is a simple thing to make. I would love to know what it does. 

This is all pharmacology. These are answers to the question, what does the drug do A second point must be loudly mentioned here, one that concerns the questions, "How does it do what it does, and where does it go to do it " Allow me to tell a tale based on an old, made up, Sufi legend. 

List four molecules that have this function. You should name the additional pathway where each of these is found and briefly describe what it does in this second pathway. Do not use a redox cofactor as one of your choices.
