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.

Acromegaly is a relatively rare chronic disease.

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.

Sympathetic afferent fibers originate from a visceral organ, course in the thoracolumbar rami communicantes, have cell bodies located in dorsal root ganglia, and terminate in the gray matter of the spinal cord.

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.

Wood is the usual end product of a forestry operation.

An increase in the demand for wood results in improved recovery and less residual biomass in the forests.

Wood as found in trees and bushes was of primary importance to ancient humans in their struggle to control their environment.

Isolated protoplasts are a unique tool for genetic manipulation of plants.

Das Buch enthält die Beiträge der Tagung "Neurowissenschaft und Ethik", die 1986 in Jakobsberg bei Bonn auf Einladung des Bundeskanzlers stattfand und sich mit den ethischen Fragen befaßte, die in den sich rasch entwickelnden Neurowissenschaften und der Neuromedizin eine Rolle spielen und schon jetzt in die öffentliche Diskussion eingetreten sind.

Die homonymen Hemianopsien - halbseitige, beide Augen betreffende Gesichtsfeldausfälle - sind so häufig, daß sie zum klinischen Alltag gehören.

This thorough study is an assessment of the risks involved with the deliberate release of microorganisms modified by means of genetic engineering.

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.

In this book the latest data available on transduction mechanisms of drug stimuli are presented.

One of the most impressive works of scholarship in the field of experimental pharmacology has been the Heffter-Heubner Handbuch der experimentellen Pharmakologie, internationalized some years ago under the title Handbook 0/ Experimental Pharmacology and kept up to date by a series of numbered Ergiin- zungswerke or supplementary volumes which have now replaced in importance the original Handbuch.

This is the second time that I have had the honor of opening an interna- tional symposium dedicated to the functions of the hippocampus here in Pecs.
