Wetlands of Bottomland Hardwood Forests
1st Edition
Volume 11
J.R. Clark + 1 more
English
These Proceedings comprise two parts. Part I contains eight contributed papers on hydrology, fauna, soils, forests, agriculture and ecology. Part II comprises reports resulting from the five interdisciplinary workgroups whose participants included ecologists, botanists, zoologists, engineers, hydrologists, agrologists, dendrologists, resource managers and other specialists. Their aim was to evaluate conservation and management practices for wetland portions of the bottomland forests of the southeastern United States and to provide technical advice to responsible federal agencies. Thus the book is a state-of-knowledge review of scientific literature and current research, particularly that necessary to understand the effects of alterations such as forest clearing, land drainage or levee building that impair natural functions, i.e. production of timber, maintenance of water quality, flood water storage, support of migrating waterfowl and fish, carbon dioxide balance of the atmosphere etc.
Basic Elements
1st Edition
Volume 5A
English
Developments in Soil Science, 5A: Soil Chemistry: A: Basic Elements focuses on the advancements in the processes, methodologies, principles, and approaches involved in soil chemistry. The selection first elaborates on the composition of the soil, chemical equilibria, and surface interaction between the soil solid phase and the soil solution. Topics include properties of the liquid layer adjacent to the solid phase, influence of the interaction between solid and liquid phase on soil properties, reactions involving the transfer of protons and/or electrons, calculation of equilibrium constants from thermodynamic data, solid phase components, and gas phase. The manuscript then takes a look at the adsorption of cations and anions by soil, common solubility equilibria in soils, and transport and accumulation of soluble soil components. Discussions focus on solute displacement in soil, transport with and in the liquid phase, iron oxides and hydroxides, carbonate equilibria, anion exclusion at negatively charged surfaces, and highly selective adsorption of cations by soil. The text ponders on the pollution of soil, saline and sodic soils, and chemical equilibria and soil formation, including weathering and soil minerals, reverse weathering, sodication of soils upon irrigation, chemical aspects of the reclamation of saline and sodic soils, and recognition and prediction of soil pollution. The selection is a valuable source of data for researchers wanting to study soil chemistry.
Rapidly Quenched Materials
1st Edition
H. Fredriksson + 2 more
English
The 327 papers in this two-volume set cover a wide range of topics concerning the production, processing and properties of rapidly quenched melts. Various techniques for the production of non-equilibrium materials are also discussed, including solid state amorphization by rapid interdiffusion and thermobaric quenching.

Experimental Heat Transfer, Fluid Mechanics and Thermodynamics 1993
1st Edition
M.D. Kelleher + 3 more
English
The papers contained in this volume reflect the ingenuity and originality of experimental work in the areas of fluid mechanics, heat transfer and thermodynamics. The contributors are drawn from 27 countries which indicates how well the worldwide scientific community is networked. The papers cover a broad spectrum from the experimental investigation of complex fundamental physical phenomena to the study of practical devices and applications. A uniform outline and method of presentation has been used for each paper.
Control of Membrane Function: short-term and long-term
1st Edition
J.M. Ritchie + 2 more
English
A critical factor in cell-to-cell interactions is the presence in the cell membrane of highly specific ion channels controlled by specific receptors that are bound to, and activated by, a gamut of external hormones and neurotransmitters. Through both this action on ion channels, and action on other membrane components (such as G-proteins), extracellular signals alter intracellular events, usually through the mediation of second messengers, and so provide the basis for the transduction mechanism connecting extracellular signals with intracellular effectors. This volume deals with the various ways that such membrane function is controlled.
Time-of-Flight Mass Spectrometry and its Applications
1st Edition
E.W. Schlag
English
The resurgence of time-of-flight mass spectrometry (TOF-MS) has had its origin in the simplicity of construction and application of such instruments together with the high transmission and the great increase in resolution that has been achieved. The instrument lends itself naturally to a coupling with pulsed laser sources, though this is not a prerequisite. It also affords a time resolution far beyond that traditionally achieved with mass spectrometric rapid scan techniques - a recent example being the real-time analysis of a multi-component mixture from an automobile exhaust. Furthermore, the mass range appears to be extremely large: mass up to 500 kDa and beyond what is being readily measured in the laboratory today.The present set of contributions attempts to give a survey of current applications from many of the active groups in the field. A variety of new applications are considered which are no doubt just the beginning of large new areas of application. By presenting this work in book form it is hoped that it will be of help to the many groups intending to initiate work in this rapidly expanding new area of mass spectrometry.
Reliability Analysis and Prediction
A Methodology Oriented Treatment
1st Edition
Volume 15
K.B. Misra
English
This book equips the reader with a compact information source on all the most recent methodological tools available in the area of reliability prediction and analysis. Topics covered include reliability mathematics, organisation and analysis of data, reliability modelling and system reliability evaluation techniques. Environmental factors and stresses are taken into account in computing the reliability of the involved components. The limitations of models, methods, procedures, algorithms and programmes are outlined. The treatment of maintained systems is designed to aid the worker in analysing systems with more realistic and practical assumptions. Fault tree analysis is also extensively discussed, incorporating recent developments. Examples and illustrations support the reader in the solving of problems in his own area of research. The chapters provide a logical and graded presentation of the subject matter bearing in mind the difficulties of a beginner, whilst bridging the information gap for the more experienced reader. The work will be of considerable interest to engineers working in various industries, research organizations, particularly in defence, nuclear, chemical, space or communications. It will also be an indispensable study aid for serious-minded students and teachers.
Chromatography Today
5th Edition
C.F. Poole + 1 more
English
Chromatography Today provides a comprehensive coverage of various separation methods: gas, liquid, thin-layer, and supercritical fluid-chromatography... and capillary electrophoresis. Particular attention is paid to the optimization of these techniques in terms of kinetic parameters and retention mechanisms. When these facts are understood, method selection and optimization becomes a more logical process. Sample preparation methods are treated fully as they frequently represent an integral part of the total analytical method. Also described are preparative-scale separations used for isolating significant amounts of product which are generally achieved under conditions that are not identical to those used for analytical separations. The most common hyphenated methods used for sample identification are discussed from the perspective of the information they yield and the requirements of common interfaces. The scope and level of discussion are designed to be appropriate for various user groups. This book should be suitable for use as a graduate-level student textbook in separation science, a text for professional institutes offering short courses in chromatography, and as a self-study guide for chromatographers to refresh their knowledge of the latest developments in the field. The book is extensively illustrated with over 200 figures, 110 tables and 3,300 references, largely to the contemporary literature.

The objective of this book is to provide information to be used as a basis for evaluating the fragile, shaky structure of global food production. The volume analyses the data by region and by intensity of cultivation; and furnishes information about the yield response, giving some indication of the health of the plants. It will be invaluable to all plant and crop scientists as well as to agriculturalists.
