It was later confirmed by Ide and Chung [119] that these observations were also valid for thermotropics. Small-diameter rods of a longitudinal PLC (a copolyester based on 2,6-hydroxynaphthoic acid, terephthalic acid and p-aminophenol) were annealed above its crystal melting temperature in the nematic state for different periods of time. The dependence of the Young modulus at room temperature on the

With the latter background to the problem and the framework for chemical weathering in mind, the author would like to outline the plan that will be followed for the remainder of this paper (1) the study area will be described from the standpoint of hydrogeologic environment (geology, topography and climate) and the hydrodynamics and general aspects of the groundwater... 

With thermodynamic background and general structural features relevant to ligand affinity enumerated, attention may now be turned to the detailed structural aspects of the active site and its surroundings. As was shown crudely in Figure... 

The objective of this chapter is to highlight fundamental chemical and physicochemical aspects of general importance for sewer systems and in-sewer processes. The contents are selected with this in mind, and the focus is on chemical and physicochemical concepts adapted to this purpose. The chapter is written to serve as a solid background for understanding process-related aspects considering the sewer as a reactor.

Part I gives a general introduction and presents the theoretical, methodological and experimental aspects of thermal risk assessment. The first chapter gives a general introduction on the risks linked to the industrial practice of chemical reactions. The second chapter reviews the theoretical background required for a fundamental understanding of mnaway reactions and reviews the thermodynamic and kinetic aspects of chemical reactions. An important part of Chapter 2 is dedicated to the heat balance of reactors. In Chapter 3, a systematic evaluation procedure developed for the evaluation of thermal risks is presented. Since such evaluations are based on data, Chapter 4 is devoted to the most common calorimetric methods used in safety laboratories. 

Several comprehensive review articles have appeared in recent years dealing with general aspects and applications of chiral CE separation.f A comprehensive list of more than 280 drugs separate by chiral CE, including the respective chiral selectors and background electrolytes, appears in a review article by Giibitz and Schmid. Chiral CE has also... 

Against this background the Handbook of Environmental Chemistry will discuss the environmental aspects of the industrial use of polymers in two volumes called Polymers - Opportunities and Risks I General and Environmental Aspects and Polymers - Opportunities and Risks II Sustainability, Product Design and Processing. The scope of these volumes is to take a critical view on the chances and potential of polymers, recognizing their risks in reference to enviromnental issues arising from their production and application. 

Kalantary makes a general outline on mycotoxins and fusarium toxins as environmental toxicants, their mycotoxicosis, the historical background of trichothecene mycotoxins and toxicological aspects. 

In this article the general outline on mycotoxins and fusarium toxins as environmental toxicants their mycotoxicosis, the historical backgrounds of trichothecene mycotoxins chemistry and toxicological aspects were described. In order to protect the environment as well as human from these toxins and also to find a potential antidote for these toxins it is worthy to work in this area of research. 

I recall that ten or fifteen years ago one of the questions was Is it really useful to lower blood pressure The consensus at that time seemed to be that you had better leave it alone. For a talk presented in mid-1955, I was interested in getting some reflection of the amount of interest in hypertension and its therapy, and plotted as a reflection of interest the number of publications that appeared per year, covering the chemistry, pharmacology, and clinical aspects of hypertension. Using the same general background of available literature, this chart shows clearly the rapid increase in interest in hypertension and its therapy as reflected by the literature.
