Some General Definitions

Before going further let us remember the general definitions of such notions as solubility, solidus, and Hquidus.

After a listing of some general definitions relating to crystalline polymers (Section 1), the subject is divided into sections dealing, successively, with local structural arrangements at the scale of a few bond lengths (Section 2), morphological aspects (Section 3), molecular conformation within polymer crystals (Section 4) and, finally, kinetic aspects of crystallization (Section 5). An alphabetical index of terms is provided for the convenience of the reader. 

The Canadian Income Tax Act IT-285R2 dated March 31, 1994 gives some general definitions and remarks on depreciation of property and capital cost allowance. Schedule II lists the types of property divided into classes, percentage depreciation and description of the property. Some examples are given in Table 5.4. 

There are many such laws governing different types of measurements. The three most frequently used will be discussed in later sections of this chapter, but first some general definitions and the concept of the random variable are introduced. 

Some general definitions of a second order reaction... 

We have seen that a base can be defined as combining with a proton and, therefore, requires at least one lone pair of electrons. A more general definition of acids and bases, due to G. N. Lewis, describes a base as any species (atom, ion or molecule) which can donate an electron pair, and an acid as any species which can accept an electron pair— more simply, a base is an electron-pair donor, an acid an electron-pair acceptor. Some examples of Lewis acids and bases are ... 

The definite eause of the slip phenomenon that oeeurs within an impeller is not known. However, some general reasons ean be used to explain why the flow is ehanged. 

A general definition of log P and log D, in its simplest form, can be given as the logarithm of the ratio (P or D) of the concentration of species of interest (the drug in a pharmaceutical context) in each phase, assuming the phases are immiscible and well separated prior to analysis. P is defined as the partition coefficient, whereas D is the distribution coefficient. However, the simplest form does not reveal some of the intricacies of the determination and use of these parameters, and further explanation is necessary. 

Conventional rubber compound analysis requires several instrumental techniques, in addition to considerable pretreatment of the sample to isolate classes of components, before these selected tests can be definitive. Table 2.5 lists some general analytical tools. Spectroscopic methods such as FTIR and NMR often encounter difficulties in the analysis of vulcanised rubbers since they are insoluble and usually contain many kinds of additives such as a curing agent, plasticisers, stabilisers and fillers. Pyrolysis is advantageous for the practical analysis of insoluble polymeric materials. 

This rather general definition conveys some idea of the properties of this elusive substance. 

The agents in this class are bicyclophosphates and bicyclothiophosphates. This class of agents is not specifically listed in the Chemical Weapons Convention nor is it covered by the language of the general definitions in the Schedules. Some of these chemicals have been used as fire retardants, oil lubricants, and for medicinal research. They also occur as breakdown products in some synthetic turbine engine lubricants and some rigid polyurethane foams. 

Before scientifically sound research can be performed on a subject, clear definitions must be set. Although, this may seem a logical step, Osborn (Osborn et al., 1988) highlighted that this has been a stumbling block for research in safety science since its inception. Definitions of concepts like accidents, incidents, near misses, risk, and safety, are known in the field of safety science, but interpreted differently in various situations. Unclear and ambiguous definitions lead to misinterpretations and confusion and must be avoided. Therefore, some general concepts used in safety science and the definitions used in this thesis are discussed in this Section. In the remainder of this thesis specific concepts will be defined where appropriate and can also be found in a list of acronyms and definitions presented in the beginning of this thesis. 

Figure 5. The limiting (gravitational) mass Mum, according to generalized definition given in the present work, is plotted as a function of the Bag constant. Solid (dashed) lines show the results for the GM3+Bag (GMl+Bag) model. In both cases we take a = 30 MeV/fm2. The values of some measured masses of compact stars in radio pulsars and in Vela X-l and Cygnus X-2 are also reported for comparison.

Studies of the simple electron transfer properties of coordinated dioxygen are in a preliminary stage. The definition of reactivity patterns is obscured by inconsistencies and the lack of key pieces of information, as indicated by the comments above. Nevertheless, there is hope that some general features will emerge ...
