Several model systems have been used to understand the cellular and molecular mechanisms of differentiation of mammalian nerve cells. Each model system has unique advantages and disadvantages and is suited for the study of only certain aspects of differentiation. In this book, the techniques of these models and the usefulness and limita­ tion of each model system are discussed. An awareness of the use and misuse of each model system is importa...

While translating this book, I was in close communication with the author, S. S. Shvarts (Schwarz), who read and commented on the entire translated manuscript. In particular, any ambiguities as to the identity of organisms described only by common names in the original text were removed, because the author kindly supplied the Latin names in all such cases. Com­ mon names are retained in the translation, but the Latin names are also added where...

Conventional food safety and quality research have traditionally dealt with the whole organism or food product, either plant or animal, or with the microorganisms that associate with these food-producing plants and ani­ mals at various stages of growth, development, and maturation. However, conventional research methods no longer are sufficient to bring about the improvements in quality and safety of foods that are demanded in today's marketpl...

The past decade has witnessed a vigorous growth in activities toward the development of a variety of biomedical devices ranging from the simple A-V shunt to the complex artificial heart. Re­ search and development teams have been created comprising engi­ neers, material scientists and clinicians and, perhaps for the first time, such groups are collaboratively bringing their respec­ tive talents to bear on problems associated with defects in th...

These papers stem from the ISOTT Meeting held at Churchill College, Cambridge, from July 27th to 30th, 1986. Although the sun did not shine so brightly as during the Cambridge meeting in 1977, the communications and discussions were as lively and informative and some heat, as well as light, was generated in the presentation of differing views. The meeting was conducted in a generally informal way which allowed maximum time for discussion but t...

Scope of the book, and acknowledgements.- The articles are focused on 'real problems' in body-fluid analysis, typically with a final chromatographic separation of ~g or often ng amounts if the aim is quantitation. The pitfalls may not be realized by a typical chemist (cf. remarks in #A-3), but he may excel in metabolite iden­ tification - which this book covers to a fair extent. Where identity is known, and the metabolite could interfere in th...

The risks of measuring risk.- Session I: Statistical Inference of Risks.- The proper interpretation of significance tests in risk assessment.- Remarks on sequential designs in risk assessment.- Epidemiologic studies of toxic response ¿ significance requirements.- Biological models in epidemiology: radiation carcinogenesis.- Session II: Risks of Prenatal Exposures.- Dose-response relationships for adult and prenatal exposures to methylmercury.-...

This translation from Russian into English of the monograph Hematopoi­ etic and Lymphoid Tissue in Culture by E. A. Luriya provides us for the first time with a comprehensive review of the massive amount of work carried out in the USSR in this important area of biological research. Historically, the pioneering tissue culture studies of Maksimov, Popov, Chasovnikov, and their colleagues working in Russia in the early part of this century provid...

The Cargese Summer Institute 1975 on Weak and EZeotromagnetio Interaotions at High Energies was organized by the Universite Pierre et Marie Curie (M. LEVY et J. L. BASDEVANT)~ the KathoZieke Universiteit te Leuven (R. GASTMANS) and the Universite CathoZique de Louvain (D. SPEISER~ J. WEYERS) who made in 1973 the first oon­ taots with some Zeoturers~ who~ on the advioe of NATO joined their efforts and worked in oommon. It was the 16th Summer In...

Microbiology has undergone a number of metamorphoses in its relatively brief existence. It has been in approximate succession, morphology, epidemiology, biochemistry, genetics, and molecular biology. It is also becoming a significant parcel of cell surface studies. The one embodiment which has remained elusiv- particularly for bacteriology - is the taxonomic one. This may have been a blessing in disguise because it encouraged microbiologists t...

During August 1980 a group of 85 physicists from 57 laboratories in 21 countries met in Erice for the 18th Course of the International School of Subnuclear Physics. The countries represented were Argentina, Austria, Belgium, Bulgaria, Canada, China, Colombia, Czechoslovakia, the Federal Republic of Germany, France, Hungary, Israel, Italy, Japan, the Netherlands, Poland, Spain, Switzerland, the United Kingdom, the United States of America, and ...

In 1977 I was asked to prepare aseries of twenty lectures introducing the design of real-time software to undergraduate electrical engineers at the University of Essex. At that time the advent of low-cost microprocessors was causing a minor revolution in the computer industry. The decreasing cost of hardware resulted in a mushrooming of the number of real-time applications being attempted. Many of these innovations were conducted by electrical...

The central theme for this volume was chosen since consumers have great interest in purchasing low fat, low salt and reduced cholesterol meat, poultry and fish products. As in past volumes, experts in the field have been chosen to write chapters with emphasis on their breadth of knowl­ edge in each specific area. Efforts were also made to obtain authors from different countries in order to give the book a worldwide perspective. Chapter I stres...

Einerseits sind Chirurgen, Kardiotechniker und Intensivmediziner mit einer rasanten Weiterentwicklung von Kreislaufassistenzsystem konfrontiert, andererseits mit der ständigen Optimierung etablierter Verfahren der Herz-Lungen-Maschinen-Chirurgie. Die Themenbereiche des vorliegenden Buches sind: - Intraaortale Ballongegenpulsation - Extrakorporale respiratorische Unterstützung - Ventrikuläre Pumpsysteme Es bietet dem Leser eine aktuelle Informa...

Es sollen neben der reinen Praxis der Werkstatt die wissenschaftlichen Grundlagen der Arbeitsverfahren beleuchtet, nicht minder aber die wirtschaftlichen Fragen zur Diskussion gestellt werden." Mit dieser Zielsetzung wurde die Werkstattstechnik 1907 von Georg Schlesinger gegründet. Die für diesen Band ausgewählten Beiträge zur Produktionstechnik aus den Jahren 1907-1992 spiegeln die Entwicklung vom Beginn der Massenfabrikation bis zur fraktale...

Das Handbuch für Webtexter fasst ein heißes Eisen an: Texten für das Internet. Wie unterscheiden sich Webtexte von ihren gedruckten Vorfahren? Warum kann ich nicht einfach meine bewährten Konzepte ins Web übertragen? Welche Faustregeln gibt es für Texte im Web? Dieses Buch bleibt keine Antwort schuldig: Beispiele aus der Praxis belegen, wie wichtig die Wahl der richtigen Worte ist und wie man aktive, klare, persönliche, spannende, strukturiert...

Der bekannte Astronom Karl Schwarzschild (1873-1916) gilt als der Begründer der Astrophysik und als hervorragender Forscher mit einer erstaunlichen Bandbreite seiner Interessen. Arbeiten zur Himmelsmechanik, Elektrodynamik und Relativitätstheorie weisen ihn als vorzüglichen Mathematiker und Physiker auf der Höhe seiner Zeit aus. Untersuchungen zur Photographischen Photometrie, Optik und Spektroskopie zeigen den versierten Beobachter, der sein ...
