Michael Evenari's biography unfolds his exciting, manifold life: his love for botany, the confrontation with political events as a youngster and his thrilling experience of helping in the development of Israel.
The understanding of pollutant transformations, sorption and transport in soils and uptake by plants is the key to controlling contaminant movement towards groundwater and accumulation in food-chains.
The Fourth International Workshop on "e;In Vitro Effects of Mineral Dusts on Cells"e; was held on September 20 - 23, 1988 in Auberge Estrimont, Orford, Quebec, Canada.
More than 25 years ago, when ultrasound diagnostic methods were first intro- duced into gynecology and obstetrics, few of the pioneers of these techniques sus- pected what importance sonographic diagnosis was destined to assume.
Dieses Sammelwerk gibt neben einer Einführung in die makroskopische Anatomie der Regenbogenforelle eine detaillierte Beschreibung der Histologie der einzelnen Organe bzw.
Given the problems of the environment in relation to the ever-growing civi- lization activities of man, it is not surprising that in recent years more and more related data have been collected, phenomena have been observed and concerns have been expressed.
The floricultural industry has been undergoing an unprecedented revolu- tion in terms of the type of commodity produced and the production and marketing technology in both developed and developing countries.
During the intensification of research activities in the Southern Ocean in recent years, both at national levels and through international cooperation in such projects as BIOMASS with its FIBEX and SIBEX phases, the need was felt increasingly for closer collaboration between biologists, meteorologists, and oceanographers in the study of the interaction between the atmospheric forces, the water masses, and the living resources.
This preface is being written at a time of exceptional public interest in the North Sea, following media head- lines on toxic algal blooms, the mass mortality of common seals, and concern over pollution levels.
An overview of speciation theory reveals an increasingly held view that many events leading to the origin of new species occur in transient, unstable populations.
The concept of controlled release has attracted increasing attention over the last two decades, with the applications of this technology proliferating in diverse fields in- cluding medicine, agriculture and biotechnology.
Properly treated sewage effluent becomes an alternative source of irrigation water, and at the same time it provides a convenient means of sewage disposal through land treatment to prevent potential health and environmental hazards caused by uncontrolled flow of wastewater.
In March, 1983 a workshop on Pollutants in Porous Media was hosted by the Institute of Soils and Water of the Agricultural Research Organi- zation in Bet Dagan, Israel.
Communication is both a prerequisite and manifestation of social organization and in this sense several chapters of this volume are aimed to investigate the way vocal communication serves its ultimate function of maintaining social organization.
With improved microscope and preparation techniques, studies of histo- logical structures of plant organisms experienced a revival of interest at the end of the 19th century.
Wood is formed in an essentially water-saturated environment in the living tree, and the cell wall remains in this state until the water flow from the roots is interrupted, such as by felling the tree.
In Physical Processes in Estuaries the present day knowledge of the physics of transport phenomena in estuaries and their mathematical treatment is summarized: It is divided into following parts: - Water movements in estuaries - Estuarine fronts and river plumes - Internal waves and interface stability - Fine sediment transport, aggregation of particles, settling velocity of mud flocs - Sedimentation and erosion of fine sediments.
It is widely recognized that spiral grain in trees severely reduces the value of sawn timber through warping and loss of strength, and that it also causes problems for other wood uses as diverse as transmission poles or plywood.
The structural complexity of lignin has continually challenged the in- genuity of researchers to develop suitable methods for its charac- terization prior to and following a wide variety of chemical, biologi- cal, and physical treatments.
Advances in Comparative and Environmental Physiology provides comprehensive, integrated reviews giving sound, critical, and provocative summaries of our present knowledge in environmental and comparative physiology, from the molecular to the organismic level.
There can be little doubt that, to use the parlance of the advertising world, the elasmobranch fishes have a "e;high profile image"e; in today's world.
Von der Arbeits gruppe Systemforschung an der Universität Osnabrück wird im Auftrag der International Union of Biologica1 Sciences (IUBS) ein Projekt zur Erstellung von sogenannten Element-Konzentrations Katastern in Ökosystemen (ECCE) entwickelt, das alle großen Ökosysteme der Erde einschließen soll.
