Inorganic Nitrogen in Plants and Microorganisms summarizes new experimental data, ideas and conclusions on the whole metabolic spectrum: - transport through the cell membranes, - the distribution within plant organs, - nitrate and nitrite reduction with their complicated genetic and physiological regulation, - the assimilation of ammonium and dinitrogen.
Die Datenmengen, die bei der Modellierung, der Simulation und der Überwachung von Umweltprozessen anfallen, sind heute schon so groß, daß sie nur noch mit Supercomputersystemen in verantwortbaren Zeiten sinnvoll bearbeitet werden können.
"e;The problems involved in separating complex macromolecules require under- standing not only the chromatographic process but also the physicochemical behavior of the solutes.
Supercomputing is an important science and technology that enables the scientist or the engineer to simulate numerically very complex physical phenomena related to large-scale scientific, industrial and military applications.
Genital Papillomavirus Infections provides a state of the art survey on the clinical aspects, diagnosis, treatment, and prevention of genital papillomavirus infections, written by experts in the respective fields.
Rarely have the many mechanisms that might underlie neural plasticity been examined as explicitly as they are in this broad, lavishly illustrated treatment of plasticity in the somatosensory system.
Starting with the description of meteorological variables in forest canopies and its parameter variations, a numerical three-dimentional model is developed.
The purpose of this volume is to highlight some current areas of poxvirus research which are likely to be particularly fruitful in the upcoming few years.
The new field of applied genetic research, genetic toxicology and mutation research investigates the muta- genicity and cancerogenicity of chemicals and other agents.
Professor Hermann Remmert, führender Ökologie-Experte und Autor zahlreicher wissenschaftlicher Publikationen, gibt hier eine gut lesbare und auch für den Laien verständliche Einführung in die viel-diskutierte Thematik: Naturschutz.
The new field of applied genetic research, genetic toxicology and mutation research investigates the mutagenicity and cancerogenicity of chemicals and other agents.
Roughly nine years ago, the two editors met for the first time in Amsterdam, the Netherlands at the EURO III meeting (organized by the Association of European Operational Research Societies) there.
This monographic work authored by eminent neurophysiologists will be of major interest to researchers investigating the visual system or working in behavioral neuroscience and sleep research.
All relevant ecological aspects of plankton, especially seasonal changes in the species composition, the role of competition for limiting resources in species replacements, the role of parasitism, predation and competition in seasonal succession are treated in detail considering phytoplankton, zooplankton and bacteroplankton.
Leading international experts contribute to this selection of reviews covering the merging fields of growth factors, differentiation factors, and cytokines.
With the growing recognition during the last two centuries that the Earth has an immense age and processes over long periods of time have changed the morphology and composition of the Earth's crust, geologists have become increasingly interested in determination of absolute ages.
In a very real sense, much of North American physiological plant ecol- ogy began in the Basin and Range and has been researched there over the last four decades.
This two-volume treatise, the collected effort of more than 50 authors, represents the first comprehensive survey of the chemistry and biology of the set of molecules known as peptide growth factors.
I have been privileged to witness and participate in the great growth of knowledge on chemical carcinogenesis and mutagenesis since 1939 when I entered graduate school in biochemistry at the University of Wisconsin- Madison.

Environments at Risk is designed as an introductory text and uses case histories of environmental impact assessment to raise issues important in controlling environmental problems.
This book is based on our two books, published in the USSR and translated in a number of other countries Conservation of living nature: problems and perspectives (1983) and The levels of conservation of living nature (1985).
This book is the fruit of a study group on perception and action that worked at the Center for Interdisciplinary Research (ZiP) of the University of Bielefeld, FRG in the academic year 1984-1985.
Ecophysiology of Desert Arthropods and Reptiles starts with a new classification of the world's deserts, based upon the type of precipitation and the effect on their faunas of arthropods and reptiles.
The 5th edition of this successful Glossary has been completely revised, updated and supplemented by up-to-date terms used in genetic engineering and molecular genetics.
Infectious diseases are transmitted through variousdifferent mechanisms including person to personinteractions, by insect vectors and via verticaltransmission from a parent to an unborn offspring.
A massive phytoplankton bloom, locally termed "e;brown tide"e;, suddenly appeared in Long Island marine bays in 1985, colored the water a dark brown, decimated eelgrass beds and caused catastrophic starvation and recruitment failure of commercially important bay scallop populations.
Although retroviruses have long been associated with a variety of animal diseases, active research in the field of human retroviruses dates from the discovery of human immunodefici- ency virus (HIV) in association with acquired immunodefici- ency syndrome (AIDS).
Candida, which was discovered more than a century ago as a causative organism of oral thrush, is now thought to potentially infect almost every tissue of the human body.
