Das Lebensmittelmonitoring ist ein gemeinsam von Bund und Landern durchgefuhrtes Untersuchungsprogramm, das die amtliche Lebensmitteluberwachung der Bundeslander erganzt. Wahrend die Lebensmitteluberwachung vor allem durch verdachts- und risikoorientierte Untersuchungen die Einhaltung lebensmittelrechtlicher Vorschriften kontrolliert, ist das Lebensmittelmonitoring ein System wiederholter reprasentativer Messungen und Bewertungen von Gehalten an unerwunschten Stoffen wie Pflanzenschutzmitteln, S...

This book provides information on all aspects of modern nanoelectronics and approaches the topics from the engineering point of view, with physics used when needed. It does not require advanced mathematics or hard knowledge of chemistry. Every chapter includes questions for understanding and topics for discussion. Problems are also supplied at the end of the book on selective issues where the students need to practice some calculations and use their skills to compare different devices and system...

Modern Methods of Plant Analysis When the handbook Modern Methods of Plant Analysis, was first introduced in 1954, the considerations were: 1. the dependence of scientific progress in biology on the improvement of existing and the introduction of new methods; 2. the difficulty in finding many new analytical methods in specialized journals which are normally not accessible to experimental plant biologists; 3. the fact that in the methods sections of papers the description of methods is frequently...

The past decade has seen increased awareness of the possibility of using lipases for modification of lipids and related compounds. A major goal of application studies has been the development of systems allowing the efficient reaction of lipophilic and hydrophilic substrates with lipases. Ingenious reaction systems using immobilized, entrapped and retained lipases have been developed and some scaled up to industrial scale. This special issue includes contributions from established workers in the...

Miniturization and high throughput assay technology have brought the power of molecular evolution to the bioscience laboratory. Applied wisely, the evolutionary approach can quickly yield the desired result even where other methods have failed. From library generation by random or directed mutagenesis to screening and selection techniques -- the crucial steps for successful evolutionary biotechnology are described in detail in this practical guide that also includes valuable troubleshooting hint...

This book contains papers presented at the Second International Conference on Solid State Science and Technology 2006, ICSSST 2006, a three-day conference on solid state science and technology. The conference provides a forum for the exchange of knowledge in a highly interdisciplinary field and brings together scientists working in academic and applied research in the field of solid state science and technology.

The fields of microfluidics and BioMEMS are significantly impacting cell biology research and applications through the application of engineering solutions to human disease and health problems. The dimensions of microfluidic channels are well suited to the physical scale of biological cells, and the many advantages of microfluidics make it an attractive platform for new techniques in biology. This new professional reference applies the techniques of microsystems to cell culture applications....

The passenger pigeon, the great auk, the Tasmanian tiger—the memory of these vanished species haunts the fight against extinction. Seeking to save other creatures from their fate in an age of accelerating biodiversity loss, wildlife advocates have become captivated by a narrative of heroic conservation efforts. A range of technological and policy strategies, from the traditional, such as regulations and refuges, to the novel—the scientific wizardry of genetic engineering and synthetic biology—se...

Polymers have achieved an enviable position as the class of materials having the highest volume of production, exceeding that of both metals and ceramics. The meteoric rise in the production and utilization of polymers has been due to advances in polymer synthesis which allow the creation of specific and well-defined molecular structures, to new knowledge concerning the relationships between polymer structure and properties, and to an improved understanding of how processing can be used as a too...

With the high interest in renewable resources, the field of algal biotechnology has undergone a huge leap in importance in recent years. The book Microalgae Biotechnology - Integration and Economy treats integrated approaches to bring the high potential of microalgae into application, accelerate the development of really working production processes and put finally the products on the market. Close interaction of biology and process engineering becomes visible in the described processes. The big...

This review of recent developments in our understanding of the role of microbes in sustainable agriculture and biotechnology covers a research area with enormous untapped potential. Chemical fertilizers, pesticides, herbicides and other agricultural inputs derived from fossil fuels have increased agricultural production, yet growing awareness and concern over their adverse effects on soil productivity and environmental quality cannot be ignored. The high cost of these products, the difficulties...

This book presents a comprehensive study of the handling of fresh fruits in the developing world from harvesting to the shelf. With annual losses ranging from 30-40% due to lack of knowledge on proper handling practices and value addition, this book's information on postharvest handling and quality testing is crucial for reducing these losses and improving the quality and safety of fresh fruits in these areas. With its added focus on marketing and organized retail aspects, Postharvest Quality As...
