Word use

Moisture is a word used commonly to describe any volatile liquid or vapor iavolved ia dryiag ie, it is not used selectively to mean only water. 

Guide words—simple words used to qualify the intention in order to guide and stimulate creative thinking and so discover deviations. Table 26-2 describes commonly used guide words.

In recent years there has been a greater appreciation of the word use." As society and engineers have become more aware of the systems or process aspects of nature, it has become clear that the use of natural resources must stop short of abuse. 

Interestingly, the product actually isolated from alkyne hydration is not the vinylic alcohol, or enol (ene + ol), but is instead a ketone. Although the enol is an intermediate in the reaction, it immediately rearranges to a ketone by a process called keto-enol tautomerisni. The individual keto and enol forms are said to be tautomers, a word used to describe constitutional isomers that interconvert rapidly. With few exceptions, the keto-enol tautomeric equilibrium lies on the side of the ketone enols are almost never isolated. We ll look more closely... 

Dextrorotatory (Section 9.3) A word used to describe an optically active substance that rotates the plane of polarization of plane-polarized light in a right-handed (clockwise) direction. 

Suprafacial (Section 30.6) A word used to describe the geometry of pericyclic reactions. Suprafacial reactions take place on the same side of the two ends of a -n electron system. 

The one-pot multistep process has been named in various ways domino, cascade, tandem, timed, consecutive, transmissive, etc. Sometimes the word used does not describe the real meaning of the procedure in that there is no conformity between the customary use of the term and the chemical transformation. These terms were recently defined more pertinently [59]. 

Used oil is any oil that has been refined from crude oil or any synthetic oil that has been used and, as a result of such use, is contaminated by physical or chemical impurities. In other words, used oil must meet each of the following three criteria origin, use, and contamination. First, the used oil...

Spintronics [136-138] is a word used to describe transport in a mesoscopic junction in which the transport medium (or the electrodes) contain unpaired electron spins. There are different aspects of spintronics, but the simplest idea is that one can transport spin without necessarily transporting charge. This leads to the idea of a molecular spin transistor, and other spin phenomena such as spin valves and spin gates.

Architecture is a word used loosely to mean many different things yet it is one of the most important aspects of the design of a system and has far-reaching effects on its success. 

Titration is a general word used in many different disciplines. Any time a solution of known concentration is used to find the amount of an unknown component in another solution, it can be called a titration. Although this type of analysis is very old, it still finds widespread used in chemical analysis. Titrations are used in soil analysis to measure soil acidity, soil organic matter content, and various constituents isolated from soil, particularly ammonia. 

We see immediately that as long as the sphere stays in one 0 the probability of having two electrons with the same spin in it is very small. When the sphere overlaps with two different 0 the probability increases. How large should the sphere be It turns out that it is useful to choose the sphere in such a way that the probability of having two electrons with opposite spin is the same, independently of r [9]. In other words, using the expression of /J2.dciO icr, ncri) for r = 2, (T =/= [Pg.287]

A catalyst is a substance that increases the rate at which a chemical reaction reaches equilibrium. Catalysis is the word used to describe the action of the catalyst. Heterogeneous catalysis describes the enhancement in the rate of a chemical reaction brought about by the presence of an interface between two phases [2],... 

In Pt(lOO) and PKllO), therefore, the delay of platinum oxidation is likely the cause of the delay of the COad oxidation. As for Pt(lll), however, water is considered as the oxygen source. Therefore, the large potential shift is considered as the result of difficulty in using water as the oxygen source. In other words, using more concentrated acid affects more the COad oxidation by water than the COad oxidation by Pt-OH. 

The necessity for the somewhat long-winded wording used in SAQ 6.12 explains why Reinmuth first proposed such a shorthand notation (in 1957). 

As discussed, the major purpose of the investigation is prevention. The tone and choice of words used in the formal report should reflect the attitude of preventing a repeat of a similar incident rather than affixing the blame.
