What else

Figure 4.3b is a schematic representation of the behavior of S and V in the vicinity of T . Although both the crystal and liquid phases have the same value of G at T , this is not the case for S and V (or for the enthalpy H). Since these latter variables can be written as first derivatives of G and show discontinuities at the transition point, the fusion process is called a first-order transition. Vaporization and other familiar phase transitions are also first-order transitions. The behavior of V at Tg in Fig. 4.1 shows that the glass transition is not a first-order transition. One of the objectives of this chapter is to gain a better understanding of what else it might be. We shall return to this in Sec. 4.8. [Pg.207]

A nitrogen atom at X results in a variable downfield shift of the a carbons, depending in its extent on what else is attached to the nitrogen. In piperidine (45 X = NH) the a carbon signal is shifted by about 20 p.p.m., to ca. S 47.7, while in A-methylpiperidine (45 X = Me) it appears at S 56.7. Quaternization at nitrogen produces further effects similar to replacement of NH by A-alkyl, but simple protonation has only a small effect. A-Acylpiperidines show two distinct a carbon atoms, because of restricted rotation about the amide bond. The chemical shift separation is about 6 p.p.m., and the mean shift is close to that of the unsubstituted amine (45 X=NH). The nitroso compound (45 X = N—NO) is similar, but the shift separation of the two a carbons is somewhat greater (ca. 12 p.p.m.). The (3 and y carbon atoms of piperidines. A- acylpiperidines and piperidinium salts are all upfield of the cyclohexane resonance, by 0-7 p.p.m. [Pg.15]

The overall circulating pattern, including the circulation time and the deviation of the circulation times, can never be neglected. No matter what else a mixer does, it must be able to circulate fluid throughout an entire vessel appropriately. If it cannot, then that mixer is not suited for the task being considered. [Pg.1625]

A coking operation has about 1 million cubic meters per year of excess coke oven gas that it generally sends to flares. (A) Instead of burning this offgas in flares, what else could be done with it (B) What is the value of this gas (assume it to be essentially natural gas or methane) ... [Pg.147]

Ciroc, a French vodka made from grapes—what else —was introduced in the New York area two weeks ago, after opening out of town in Chicago. Two years in development, it was created for the United States market, and may find its way back to France eventually if it sells well here. [Pg.213]

Those of us who are strong enough, we are not supposed to be quiet and go away and die. We re not supposed to commit suicide. We have the obligation to say what we see, to share our observations. We re supposed to find one another, to work together, to have some sort of impact on the way our society is organized, and the way the economy impacts life and health. I don t know what else to do. I don t have a better plan. [Pg.99]

I have found that it helps me to stay calm and let my body and adrenals rest. That alone can make a difference. The more often I can do that, the better. And for me, a lot of getting well is learning how to set boundaries. If I don t take care of myself, I m not going to get better. I ve had to learn when I ve had enough, when to say no, when I m too tired to do any more regardless of what else is on my list. [Pg.214]

Every time a verb is mentioned, draw an action and add to your list of questions Who and what else participates in that What is its effect on their state The answers to these questions lead you to draw object types and to write postconditions these in turn lead to associations and attributes with which to illustrate the effects. [Pg.37]

Given that actions may overlap, we must take a broader view of the meaning of a postcondition. For example, sale means that, somewhere between the start and the end of the action, the wholesaler s till gets fatter by the price of the items. But does it If you compare the actual contents of the till before and after the sale, the difference is probably not the same as is documented. It depends on what else has happened during that interval other sales may have been completed the manager may have taken the cash to the bank there may have been a refund or a robbeiy. [Pg.197]

These activities are discussed below with respect to the case studies presented in (chapters 2-14) in this book. The aim is to highlight what else needs to be done in the future. [Pg.477]

Hell, what else can one ask for Well, as it turned out, we can ask for more. I found this out when, after ten years of dedicated, loyal, and exceptional service, they promoted someone over me for the superintendent s position. [Pg.13]

If the answer to either question 7a, 7b, 7c, or 7d is NO, or if the answer to question 7e is YES, then brainstorm what else would have to occur or what other conditions would have to be satisfied for Fact B to lead to Fact A. Generate the questions or list the data needed to answer the hypothetical questions/concerns. [Pg.195]

If you add a lot of series resistance - enough to limit the current heating - they behave like a ratty zener and can recover lots of times. You have to see what else happens when you add that much resistance - might destroy other needed features - or maybe it s tolerable. [Pg.18]
