Catalytic Polymerization of Olefins
1st Edition
Volume 25
T. Keii + 1 more
English
This book covers the proceedings of a symposium which was attended by researchers from all over the world who reported on and discussed recent advances in the field of catalytic polymerization of olefins.Over two decades have elapsed since the discovery of the Ziegler-Natta catalyst. Tremendous research effort has been aimed at improving this marvelous catalyst. In twenty-five years since the first publication, more than 15,000 papers and patents on the subject and on related subjects have appeared. This effort has yielded new generations of Ziegler-Natta catalysts with superior activity and stereospecificity. The complexities arising from the heterogeneity of the catalyst, however, have hindered understanding of the catalytic processes which take place on the catalyst surface. Nevertheless, many fundamental features of the catalyst system have now been clarified reasonably well. Recently a highly active homogeneous catalytic system has been developed, which is capable of catalyzing even isotactic polymerization of propene. There is no doubt that this finding will not only contribute to our understanding of the detailed mechanism of polymerization but also stimulate the development of various kinds of tailored polymers. Thus this subject will remain of paramount importance in the development of chemistry and polymer science for a long time to come.
Kinematic Hydrology and Modelling
1st Edition
Volume 26
M.E. Meadows + 1 more
English
Requiring little mathematical background, the book provides tools for hydraulic engineers and hydrologists concerned with estimating catchment runoff and floods. It condenses widely spread research literature on the subject of kinematic hydrology and emphasizes basic principles so it should be of value to students and teachers in these areas. The book is comprehensive and yet written in a basic way enabling practitioners to pick out relevant sections and apply them to real problems. It also contains a valuable collection of charts and equations as well as simple computer programs for modelling catchment runoff and stream flow using the kinematic equations.A wide spectrum of hydrological processes can be analyzed using the kinematic equations. Overland flow, stream flow and even groundwater flow can be studied. A review of the assumptions behind the theory indicates where alternative equations are more accurate. The book thus provides tools for hydrological simulation, stormwater system design and catchment management. It will be particularly useful for professors and students in postgraduate and senior years in hydrology, and practicing engineers and hydrologists in stormwater, flood and water resources fields.
Spider Mites
1st Edition
Volume 1B
Bozzano G Luisa
English
This two-part volume with contributions from more than 50 international specialists, provides an up-to-date text and brings together facts and views of acarologists specialized in various aspects of the biology of spider mites. The need for such a treatment of scientific progress and recommended topics for future research exists among students, commencing in the study of acarology and plant protection, as well as among those engaged in acarological research and teaching. Both books will serve to provide a synthesis of much of the knowledge on basic and applied aspects of the biology of spider mites and their natural enemies; stimulate students to analyse critically the views propounded by the authors of the book, and instigate research into environmentally safe and cost effective means of pest control.
Liquid Chromatography Detectors
2nd Edition
Volume 33
R.P.W. Scott
English
The renaissance of liquid chromatography took place in the late 1960's and early 1970's. The first edition of this book published in 1977 described the detectors that were available at that time and which provided a performance matching that of the contemporary equipment with which they were associated. It is interesting to note that the most popular detectors then (the UV detector, the refractometer detector, the fluorescence detector and the electrical conductivity detector) are still the most commonly used detectors nearly a decade later. Detector design, however, has changed very significantly over the intervening years. Modern high efficiency columns provide very narrow peaks and very fast separations, and thus the physical design of the detectors had to change to meet these new challenges. In 1977, there was little real understanding of the important role played by the detector in the overall function of the chromatographic system and although some of the factors were pointed out in the first edition of this book, in retrospect they appeared to be little understood.This second edition gives an entirely new presentation of the subject of liquid chromatography detectors. It contains sections dealing with the fundamental aspects of the interaction between columns and detectors and the interaction between ancillary equipment and the detector. It brings the reader up-to-date with new designs and novel detecting systems that have been developed since 1977 and extends significantly the subject of the association of the liquid chromatography detector with spectroscopic techniques. In particular the book now explores the association of liquid chromatography with nuclear magnetic resonance, infrared and atomic absorption spectrometry. This book not only gives a comprehensive treatment of the subject of liquid chromatographic detectors and provides a rational procedure for defining their performance and so permit valid comparisons, but also discusses detector performance in relation to the whole of the chromatographic system.

Progress in Medicinal Chemistry
1st Edition
Volume 23
English
There are five main subject areas in this volume in the series on medicinal chemistry. The first is a review of the understanding of Alzheimer's disease and the development of drugs for its treatment; the second, looking at recent efforts in modifying a naturally occuring anticancer (campothecin) for chemotherapy; the third covers the problem of getting a drug to a specific site within the context of phosphates and phosphonates; a survey of sterilization using aldehydes for the destruction of microbes both inside and outside the human body is reviewed in the fourth; and the last chapter is an account of the progress made in the biologically active enantiomer for complex synthetic asymmetric drug molecules.
Fluoride Research 1985
Selected Papers from the 14th Conference of the International Society for Fluoride Research, Morioka, Japan, 12-15 June 1985
1st Edition

Some of the world's leading scientists in fluoride research have contributed to the 49 research and review papers in this book. While different methods for fluoride determination have been known for many years, information concerning the determination of submicrograms of fluoride is lacking. This volume contains articles that describe newly developed techniques used for fluoride determination and their application to the analysis of biological samples. In addition, facts about inorganic fluoride air pollution in several countries and its influence on vegetation, animals, and humans are described. Although the book is primarily directed to investigators in the area of fluoride research, it should be of value to public health officials, medical, dental, and veterinary scientists, ecologists, and environmental scientists.
