Obscure subject

Given previous film s portrayal of Bond as having expert knowledge on obscure subjects, ranging from the makeup of brandy Diamonds Are Forever) to limited astronaut training (Moonraker), it would not be hard to envision Bond learning the necessary details himself, thus rendering Natalya s presence is superfluous. 

Since 1970 the subject of amoiphous semiconductors, in particular silicon, has progressed from obscurity to product commercialisation such as flat-panel hquid crystal displays, linear sensor arrays for facsimile machines, inexpensive solar panels, electrophotography, etc. Many other appHcations are at the developmental stage such as nuclear particle detectors, medical imaging, spatial light modulators for optical computing, and switches in neural networks (1,2). 

The Birch reduction of a benzenoid compound involves the addition of two electrons and two protons to the ring. The order in which these additions occur has been the subject of both speculation and study. Several reviews of the subject are available and should be consulted for details. The present discussion is concerned with summarizing data that is relevant to understanding the reaction from the preparative point of view. For convenience, reaction intermediates are shown without indicating their solvation by liquid ammonia. This omission should not obscure the fact that such solvation is largely responsible for the occurrence of the Birch reduction. 

Before starting an electrochemical promotion experiment, one should check carefully that the catalytic reaction under study is not subject to external or internal mass transfer limitations within the desired operating temperature range, which can obscure or even completely hide the electrochemical promotion effect. 

Record changes shall not obscure previously recorded information. Such audit trail information shall be retained for a period at least as long as that required for the subject electronic records and shall be available for agency review and copying. 

This book seeks essentially to provide a rigorous, yet lucid and comprehensible outline of the basic concepts (phenomena, processes, and laws) that form the subject matter of modem theoretical and applied electrochemistry. Particular attention is given to electrochemical problems of fundamental significance, yet those often treated in an obscure or even incorrect way in monographs and texts. Among these problems are some, that appear elementary at first glance, such as the mechanism of current flow in electrolyte solutions, the nature of electrode potentials, and the values of the transport numbers in diffusion layers.

The concept of a control is a device or mechanism to detect variations in the monitored procedure that are significant enough to produce a detectable result. In the case of IHC stains, the inability of subjective visual assessment to detect significant stain results has obscured this major source of variation for most users. This author has worked with quantitative evaluations of his-tochemical stains for many years. Initial attempts at quantitative evaluation of IHC stains clearly indicated that current practice does not provide adequate control of IHC stain protocols. 

Although a high level of plasma renin appears to identify a subject likely to respond to (3-blockers the relationship between the reduction in renin level and fall in blood pressure is still obscure. While some investigators claim good correlations between the reduction in renin and blood pressure others find no such correlation (20). In fact, Stokes et al (34) showed that pindolol was able to maintain the fall in blood pressure produced by chronic administration of propranolol without maintaining the reduction in renin. 

Gas-phase solvation has so far given only very indirect evidence concerning the structure and details of molecular interactions in solvation complexes. Complex geometries and force constants, which are frequently subjects of theoretical calculations, must therefore be compared with solution properties, however, the relevant results are obscured by influences arising from changes in the bulk liquid or by the dynamic nature of the solvation shells. With few exceptions, structural information from solutions cannot be adequately resolved to yield more than a semiquantitative picture of individual molecular interactions. The concepts used to convert the complex experimental results to information for structural models are often those of solvation numbers 33>, and of structure-making or structure-... 

Let us turn next to a problem in the area of dental disease, namely, dental caries. This is a disease the etiology of which is, when one considers all the current evidence, very obscure. The application to this problem of our general formula (p. 211) calls for a search for the metabolic peculiarities which may be concerned in dental caries, but unfortunately metabolic peculiarities in the field which seems most likely to be pertinentmineral metabolismare virtually unknown as of the present writing. Are they unknown because they do not exist or because they have not been looked for The latter seems most probable in view of our previous discussions related to the subject (pp. 4 and 153).
