Groundwater Discharge Tests: Simulation and Analysis
1st Edition
Volume 37
D. Clarke
English
This book describes microcomputer programs which can be used to simulate or analyse water production well and aquifer discharge test data. Computer graphics are used to help visualise the data, and output to plotters is also catered for. Simple confined aquifers, leaky confined aquifers, unconfined aquifers and a variety of boundary conditions are dealt with.The book and the microcomputer programs it describes will allow the reader to apply very flexible computer techniques to the analysis of his well and aquifer discharge test data. The speed of the microcomputer analyses will give the user the opportunity of looking at his data in more ways than he would otherwise be able to, thus giving insights into the data that would not otherwise be possible. The simulation programs permit the production of type curve data, which can then be used in comparison with the real data, or used in becoming familiar with the operation of the analysis programs.Although primarily intended for practicing hydrogeologists and universities teaching hydrogeology, this book would also be of interest to anyone having an interest in the effects of groundwater extraction. The programs will run on IBM PCs and compatibles with colour graphics.

Studies in Logic and the Foundations of Mathematics, Volume 123: Constructivism in Mathematics: An Introduction, Vol. II focuses on various studies in mathematics and logic, including metric spaces, polynomial rings, and Heyting algebras. The publication first takes a look at the topology of metric spaces, algebra, and finite-type arithmetic and theories of operators. Discussions focus on intuitionistic finite-type arithmetic, theories of operators and classes, rings and modules, linear algebra, polynomial rings, fields and local rings, complete separable metric spaces, and located sets. The text then examines proof theory of intuitionistic logic, theory of types and constructive set theory, and choice sequences. The book elaborates on semantical completeness, sheaves, sites, and higher-order logic, and applications of sheaf models. Topics include a derived rule of local continuity, axiom of countable choice, forcing over sites, sheaf models for higher-order logic, and complete Heyting algebras. The publication is a valuable reference for mathematicians and researchers interested in mathematics and logic.
Vestibulospinal Control of Posture and Locomotion
1st Edition
Volume 76
English
This volume publishes the review articles presented by the invited speakers at the Satellite Meeting to the Barany Society Meeting held in Bologna, Italy during June 1987. The subject matter in this book is divided into seven main sections. The first three present basic neuroanatomical and neurophysiological aspects of vestibulospinal reflexes and document the neck afferent and visual influences on these reflexes. The following sections deal with the control of locomotion, posture, and eye-head-trunk coordination by vestibulospinal signals. The final section provides current knowledge on the processes underlying compensation of vestibulospinal deficits. An overall review precedes each main section so that the reader is informed as to which questions are still controversial and require further investigation. In this way a basis is provided for those needing a current account of the field of vestibulospinal reflexes. Due to the extensive length of the contents, only the number of articles presented per session is listed below.
Analysis of Water Resource Systems
1st Edition
Volume 32
L. Votruba
English
Water resource systems research provides a basis for rational water management in large basins. The design and operation of water resource systems are both the most complicated and the most important tasks of water management. This book deals with the basic issues involved in the application of systems sciences to water management.A survey of the systems sciences (the general systems theory, cybernetics, systems engineering, operations research and systems analysis) is presented, as well as the methods for water resource systems analysis and for water resource systems analysis and for their evaluation. The mathematical methods used in systems theory have been given detailed treatment. Linear and dynamic programming have been used as models of optimal programming. Since many practical tasks require the simulation models of water resource systems, apart from their principles and a detailed description, the simulation language for computing programming has been included. Other methods of operations research and their application to water resource systems have been analysed and evaluated. Some of these are: models of inventory theory, models of queuing theory, graphs, network analysis, and some special methods like the out-of-kilter algorithm, the chance-constrained model and the chance-constrained model combined with the simluation model. One chapter is devoted to information and information systems in water management. The final part of the book deals with prospects for water resource systems development.The book is intended for engineers and decision-makers involved in projects, operation and research. However, it can be used by students in high schools, technical universities and by graduate students. It will serve as an up-to-date source of information about the principles and methodology of water resource analysis and design.
Automatic Methods of Analysis
1st Edition
Volume 9
M. Valcárcel + 1 more
English
This new monograph provides a comprehensive overview of the state of the art of the automation of laboratory processes in analytical chemistry. The topics have been chosen according to such criteria as the degree of consolidation, scope of application and most promising trends.The first part of the book begins with the basic principles behind the automation of laboratory processes, then describes automatic systems for sampling and sample treatment. In the second part the principal types of analysers are discussed: continuous, batch and robotic. The third part is devoted to the automation of analytical instrumentation: spectroscopic, electroanalytical and chromatographic techniques and titrators. The last part presents some examples of the application of automation to clinical chemistry, environmental pollution monitoring and industrial process control.The text is supplemented by 290 figures and 800 literature references. It is written primarily for scientists directly involved in laboratory work and those responsible for industrial planning and control, research centres, etc. It will also be of interest to analytical chemists wishing to update their knowledge in this area, and will be of especial interest to scientists directly related to environmental sciences or clinical chemistry.

Heterogeneous Catalysis and Fine Chemicals
1st Edition
Volume 41

The recession in the traditional heavy industries along with the development of advanced technologies in all the industrial countries has meant that the impact of heterogeneous catalysis in the synthesis of fine chemicals is becoming increasingly noticeable. The first International Symposium on Heterogeneous Catalysis and Fine Chemicals is to be seen in this perspective. Organised by the Laboratory of Catalysis in Organic Chemistry of the University of Poitiers within the framework of the International Symposia of the `Centre National de la Recherche Scientifique' (CNRS), the symposium provided an opportunity for contact between academic researchers and manufacturers, users (or potential users) of solid catalysts for fine chemical synthesis.Two panels of industrial and academic researchers - one on selective hydrogenation, the other on selective synthesis of substituted aromatics - showed that heterogeneous catalysis already plays a significant role in fine organic chemistry. The main topics of the symposium were introduced in six plenary lectures and three invited communications, maintaining a balance between the industrial and the academic points of view. Some 60 research papers were submitted from which the Scientific Committee selected the 35 communications (oral or poster) which fitted most closely the theme of the symposium. All are reproduced in full in this Proceedings volume.

This volume completes the account of physical methods used in biochemistry that was covered in Volume 11A, which was published in 1985. It deals with fast reaction methods, high performance liquid chromatography of peptides and proteins, fluorescence spectroscopy, neutron and X-ray scattering techniques, and also Raman and resonance spectroscopy which have in recent years been used to an increasing extent in biochemistry. This addition to the invaluable series New Comprehensive Biochemistry will be of interest to all those working in the fields of biochemistry and biophysics.
