sonst. Bücher. Zustand: Neu. Neuware - Jugular vein and carotid artery cannulations are among the most widely used surgeries in research labs around the world. These cannulations are extremely important for confirmed intravenous delivery of test substances and arterial blood collection. Cannulation reduces the stress of multiple sampling as observed in association with tail vein or orbital sinus techniques (Ling, 2003; Flynn, 1988; Cocchetto, 1983). Very few adverse effects, including a possible rise of corticosterones and a decrease in platelets, are associated with indwelling catheters except under chronic conditions (Fagin, 1983; Richman, 1980).Typically, technicians teach these skills to incoming employees and move on to graduate studies or other fields. A resulting 'oral history' of cannulation has been passed down from technician to technician. I have endeavored to capture these techniques on paper. Through the years, I have searched for and collected a number of training materials and guides for teaching purposes. This is my attempt to compile all the necessary information in one source.The contents of this manual include two cannulation procedures detailed in a format of materials, instruction, and pictorial for each step. In addition, the manual is rounded out with information regarding procedures for anesthesia, pre- and post- operatives, anatomy, bleeding techniques using catheters implanted, and rat biodata compiled from numerous sources. The content is thoroughly researched and reported based on over 80 references and 7 reviewers' suggestions.…

Buch. Zustand: Neu. Neuware - Over the past twenty-five years, the effects of the spatial distribution and scaling of resources on animal populations have been increasingly studied in wildlife biology, landscape ecology, conservation biology, and related fields. However, spatial patterns change over time. In Temporal Dimensions of Landscape Ecology: Wildlife Responses to Variable Resources, the authors discuss the effects that temporal changes in resources have on animal populations. Resource availability and quality are not distributed homogeneously over time, depending for example on predictable changes in seasons, mating and birthing cycles, unpredictable resource pulses and weather-related phenomena, ecological disturbances, and historical legacies.Temporal Dimensions of Landscape Ecology brings together chapters that address the idea of current as well as historical temporal influences on resource availability, quality, and distribution. The authors draw attention to the neglected temporal issues so important to understanding species and community responses. This book will be of interest to both wildlife and conservation students and practitioners working with temporal and spatial scale issues.…

Buch. Zustand: Neu. Neuware - Thermal drying has been recognized as an important unit operation as it is ener- intensive and has a decisive effect on the quality of most products that are dried commercially. Escalating energy costs, demand for eco-friendly and sustainable te- nologies as well as the rising consumer demand for higher quality products, have given fresh incentives to industry and academia to devote great effort to drying R&D. Fortunately, this area does not demand a massive perfusion of R&D funds to come up with valuable insights and innovations, with only a few exceptions. Indeed, there is already a sustainable level of R&D support-both in terms of human and nancial resources-around the world. Emerging economies of the world, such as China, B- zil, India, etc, have picked up the slack caused by the fully developed economies of the west moving towards nanotechnologies. Overall, the global R&D effort has been rising despite precipitous drops in North America and Europe. With 12-25% of the national industrial energy consumption attributable to industrial drying in developed countries, it is only a matter of time before high energy costs will stimulate further R&D in drying.…

Taschenbuch. Zustand: Neu. Neuware - Diese dritte Auflage wurde zusammen mit dem zweitgenannten Autor kritisch durchgesehen, ergänzt und verbessert. Ein weiteres Kapitel über geometrische Funktionentheorie und schlichte Funktionen enthält einen Beweis der Bieberbachschen Vermutung.'Der . vorliegende zweite Band der Funktionentheorie erfüllt voll die Erwartungen, die der erste Band geweckt hat. Wieder beeindrucken vor allem die hochinteressanten historischen Bemerkungen zu den einzelnen Themenkreisen, als besonderer Leckerbissen wird das Gutachten von Gauß über Riemanns Dissertation vorgestellt. Jedes einzelne Kapitel enthält ausführliche Literaturangaben. Ferner werden oft sehr aufschlussreiche Hinweise auf die Funktionentheorie mehrerer Veränderlicher gegeben. Die vielen Beispiele und Übungsaufgaben bilden eine wertvolle Ergänzung der brillant dargelegten Theorie. Der Rezensent bedauert, dass ihm nicht schon als Student ein derartig umfassendes, qualitativ hochstehendes Lehrbuch zur Verfügung stand.'Monatshefte für Mathematik.…

Buch. Zustand: Neu. Neuware -Membranverfahren werden in den Ingenieur- und Naturwissenschaften unter anderem in der Medizin-, Wasser- und Lebensmitteltechnik als Alternative zu konventionellen Verfahrensstrategien eingesetzt. Aufgrund der wachsenden Anforderungen an Prozesse in der Umwelttechnik und in der chemischen Industrie zählen Membranverfahren zu den Schlüsseltechnologien des 21. Jahrhunderts. Die zum Grundverständnis von Membranprozessen erforderlichen Zusammenhänge werden in diesem Lehrbuch und Nachschlagewerk erörtert. Ausgehend von klar dargestellten Grundlagen werden die Werkzeuge und Methoden zur Auslegung von Membranverfahren erarbeitet und anhand von Beispielen dargestellt. Des Weiteren wird der Stand der Technik sowie das Entwicklungspotential der einzelnen Verfahren vorgestellt.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg Deutsch.…
