Reasons for study

The ultimate reason for studying water clusters is of course to understand tire interactions in bulk water (tliough clusters are interesting in tlieir own right, too, because finite-size systems can have special properties). There has been...

The Characteristic Function.—The calculation of moments is often quite tedious because of difficulties that may be encountered in evaluating the pertinent integrals or sums. This problem can be simplified quite often by calculation of the so-called characteristic function of the distribution from which, as we shall see, all moments can be derived by means of differentiation. This relationship between the characteristic function and moments is sufficient reason for studying it at this time however, the real significance of the characteristic function will not become apparent until we discuss the central limit theorem in a later section. 

The primary reason for studying aqueous plutonium photochemistry has been the scientific value. No other aqueous metal system has such a wide range of chemistry four oxidation states can co-exist (III, IV, V, and VI), and the Pu(IV) state can form polymer material. Cation charges on these species range from 1 to 4, and there are molecular as well as metallic ions. A wide variety of anion and chelating complex chemistry applies to the respective oxidation states. Finally, all of this aqueous plutonium chemistry could be affected by the absorption of light, and perhaps new plutonium species could be discovered by photon excitation. 

The two main reasons for studying the reversible reaction (3) were (a) to complete the picture of the Koch reaction in terms of quantitative information and (b) to set up a scale of reactivity towards a neutral nucleophile for carbonium ions of different structure. The first item is important from a practical point of view because there are reactions competing with the carbonylation step (3), which can be divided into intramolecular and intermolecular processes. Rearrangement of the intermediate alkylcarbonium ion, e.g. 

MOLECULAR DYNAMICS STUDY OF DNA SOLUTIONS. One of the main reasons for studying water is because of its importance in biological environment. 

Mention has previously been made of the traditional analytical expertise in quantitating chemical degradation. What is not commonly known is that there are two business reasons for studying chemical degradation attendant to compound storage. In the first business reason the compound store is considered as inventory, and corporate policies and procedures relevant to inventory apply, e.g. inven-... 

Trial number and location and definition of specific crop fractions to be sampled had been a significant reason for study rejection prior to 1996. This particular guideline has helped resolve these issues in studies conducted since that time. 

Also, NIRS detection in reflectance mode can be used for TLC [762]. The main reason for studying the applicability of NIRS as an in situ detection tool in TLC is that adsorbents such as silica gel have no strong absorption in the NIR region background... 

One of the major reasons for studying the ESR of this series of Co(II)-corrinoids is that this spectral tool may give information on the mechanism of corrin-dependent enzymes. Cleavage of the Co—C—cr-bond has been studied in a few enzymes by using Co(II) ESR, and there is evidence... 

Activation is a major reason for studying the pathways and products from the breakdown of organic molecules in natural ecosystems and waste disposal systems which lead to environmental discharges [9,23,93 - 97,127,146,147,149,... 

Some of the motivational reasons for studying the subjects presented in this hook are that they are of considerable practical importance, they are challenging, and they are fun. 

Since the time of Schardinger, one of the most important reasons for studying the cyclodextrins was for the information they might yield on the structure of starch and of the well known blue iodine-starch complex. In fact, the similarity between the iodine-starch reaction and the iodine-alpha cyclodextrin reaction was first noted by Schardinger in 1911, in his final paper on the cyclodextrins. 

Because an important reason for studying ionic reactions in the gas phase, rather than in the condensed phase, is to eliminate the strong moderating effects of the solvent, it is generally desirable that the buffer gas serve only as a chemically inert physical medium in which the reactants are suspended and thermalized. In the VHP... 

The main reasons for studying rheology (stress-strain relationships) in this chapter are (1) to determine the suitability of materials to serve specific applications and (2) to relate the results to polymer structure and form. Studying structure-property relationships allows a better understanding of the observed results on a molecular level resulting in a more knowledgeable approach to the design of materials. 

We may regard the commercial polymers which have broad technical application separately. The photosensitivity of such materials, as a rule, is caused by impurities and dopants. The main reason for studying their photoelectrical processes is the clearance of the stabilization problems. 

This is one reason for studying crystal shapes. Another and more weighty reason is that crystal shapes tell us a great deal about the relative dimensions and the symmetries of the atomic and molecular space-patterns constituting the crystalline material. 

The content of this chapter is closely related to permeation, which is the transport of a solute across a layer of solvent (or membrane) under the action of a difference in activity. For example, the permeation of hydrogen through a metal foil has been studied, particularly for palladium [F.A. Lewis (1967)] and iron [J. P. Hirth (1980) H. H. Johnson (1988)]. One reason for studying the permeation of hydrogen through iron is to understand the hydrogen embrittlement of steel.
