This reference book originates from the interdisciplinary research cooperation between academia and industry. In three distinct parts, latest results from basic research on stable enzymes are explained and brought into context with possible industrial applications. Downstream processing technology as well as biocatalytic and biotechnological production processes from global players display the enormous potential of biocatalysts. Application of "extreme" reaction conditions (i.e. unconventional, such as high temperature, pressure, and pH value) - biocatalysts are normally used within a well defined process window - leads to novel synthetic effects. Both novel enzyme systems and the synthetic routes in which they can be applied are made accessible to the reader. In addition, the complementary innovative process technology under unconventional conditions is highlighted by latest examples from biotech industry.
Does a plant shrink at night and swell in the day, like an animal breathing in and out? For a long time, the Galenic concept of spiritus provided a causal explanation for human and animal life and perception. Albert the Great (1200-1280), whose honorific acknowledges among other things his pioneering work on biology, extended the concept to plants. This is only one of the remarkable concepts studied in this book, the first comparative study of Albert's concept of spiritus. It unveils the Arabic roots of his early psychophysiology and the original developments found in his mature Aristotelian paraphrases.
Essays on the depiction of animals, birds and insects in early medieval material culture, from texts to carvings to the landscape itself. For people in the early Middle Ages, the earth, air, water and ether teemed with other beings. Some of these were sentient creatures that swam, flew, slithered or stalked through the same environments inhabited by their human contemporaries. Others were objects that a modern beholder would be unlikely to think of as living things, but could yet be considered to possess a vitality that rendered them potent. Still others were things half glimpsed on a dark night or seen only in the mind's eye; strange beasts that haunted dreams and visions or inhabited exoti...
This volume contains a collection of papers from the research program “Protective Artificial Respiration (PAR)”. In 2005 the German Research Association DFG launched the research program PAR which is a joint initiative of medicine and fluid mechanics. The main long-term objective of this program is the development of a more protective artificial respiratory system to reduce the physical stress of patients undergoing artificial respiration. To satisfy this goal 11 projects have been defined. In each of these projects scientists from medicine and fluid mechanics do collaborate in several experimental and numerical investigations to improve the fundamental knowledge on respiration and to develop a more individual artificial breathing concept.
This book explores the changing perspective of astrology from the Middle Ages to the Early Modern Era. It introduces a framework for understanding both its former centrality and its later removal from legitimate knowledge and practice. The discussion reconstructs the changing roles of astrology in Western science, theology, and culture from 1250 to 1500. The author considers both the how and the why. He analyzes and integrates a broad range of sources. This analysis shows that the history of astrology—in particular, the story of the protracted criticism and ultimate removal of astrology from the realm of legitimate knowledge and practice—is crucial for fully understanding the transition ...

Audioarchive - d.h. Archive, die historische Tondokumente aufbewahren und dokumentieren - befinden sich in diesen Jahren in einer kritischen Phase: Ihre Bestände sind auf Tonträger gespeichert, die inzwischen nicht nur technisch veraltet sind (vor allem Tonbänder, aber auch Walzen, Kassetten, Schallplatten), sondern auch ihre Speicherqualität durch einen fortschreitenden, massiven Alterungsprozess in vielen Fällen eingebüßt haben. Nicht selten sind einzelne Dokumente bereits schwer geschädigt, und es besteht die akute Gefahr, dass umfangreiche Bestände unwiederbringlich verloren gehen. In den meisten Archiven ist diese Bedrohung längst erkannt worden, und aufwändige Datensicherung...
Along the last several decades, it has been progressively appreciated that immunology plays an overwhelming role in the physiology and pathophysiology of most organs, tissues, and biological systems in multicellular organisms. Accordingly, several immunological parameters are used in research and clinical laboratories with the purpose of investigating, diagnosing, and monitoring a variety of pathological conditions. The rapidly evolving field of laboratory testing in immunology poses several challenges to professionals working in research and clinical laboratories, medical practice, educational activities, in vitro diagnostic industry, and regulatory agencies. Regular analytes, such as album...
