The "e;raison d'etre"e; of hierarchical dustering theory stems from one basic phe- nomenon: This is the notorious non-transitivity of similarity relations.
Das Buch enthält die Beiträge der ersten gemeinsamen Tagung der Gesellschaft für Toxikologie und Forensische Chemie und der Gesellschaft für Suchtforschung zum Thema "Die Bedeutung chemisch-toxikologischer Analysen von Suchtstoffen - Diagnostische, forensische und therapeutische Maßnahmen".
Mathematical biology - the use of mathematical ideas andmodels in the biosciences - is a fast growing, very excitingand increasingly important inderdisciplinary field.
Die Assimilation von anorganischen Stickstoff - Nitrat, Ammonium - durch die höhere Pflanze ist für das Leben von ähnlich fundamentaler Bedeutung wie die Assimilation des Kohlenstoffs.
The Gmelin Formula Index and its First Supplement covered those volumes of the Eighth Edition of the Gmelin Handbook which had been issued up to the end of 1979.
Advances in genetics, molecular biology and gene delivery technologies in recent years have led to new gene therapy strategies for treatment of a variety of diseases.
As dogmas in stem cell research are losing their impact and recent findings regarding the use and cultivation of stem cells and tissue transplantation have opened up new therapeutic avenues, this Ernst Schering Research Foundation Workshop was initiated to highlight current and future approaches in this field.
The title "e;Stem Cells from Cord Blood, In Utero Stem Cell Develop- ment, and Transplantation-Inclusive Gene Therapy"e; suggests that more than one topic is combined in one workshop.
A number of chapters present the most novel research on testicular and epididymal functions or on more general fields of hormone action and molecular cell biology as it is now a tradition.
Reasoning in terms of molecular recognition may be traced back to Emil Fischer, who practiced the art of chemistry at Humboldt University in Prussian Berlin a century ago.
When Rolf Dahlgren and I embarked on preparing this book series, Rolf took prime responsibility for monocotyledons, which had interested him for a long time.

It is now widely accepted that cells have the ability to initiate a program of gene-directed death, a process called "e;apoptosis"e; which may also be used as an innovative strategy for therapeutic intervention in cancer therapy.
Cell biology has made an appreciable impact on the evaluation of physiological and pathophysiological processes leading to a more detailed understanding of the signaling mechanisms by which cells communicate in vivo and in vitro and modify adaptively.
The study of membrane traffic in reconstituted cell-free systems has generated an unprecedented amount of new information on the biochemistry, molecular biology and genetics of membrane-based molecular events that underly normal and abnormal cellular function.
This volume - the first of this series dealing with angiosperms - comprises the treatments of 73 families, representing three major blocks of the dicotyledons: magnoliids, centrosperms, and hamamelids.
Chemical defence by means of toxins poisonous to otherorganisms, be they animals or plants, is widespread amongstthe plant kingdom - including microorganisms as well.
