A strong synergism between the chemical, agricultural, and related sciences is highly desirable. This handbook attempts to provide in easily accessible detail up-to-date information relevant to the stability of foods and beverages. Highly qualified scientists have compiled an extraordinary amount of data on the chemical, biochemical, and microbiological stability, along with sensory aspects, of selected foods and beverages. These data have been distilled and are presented mostly in tabular form, with a minimum of commentary whenever possible.****A total of 17 chapters (10 on food, 7 on beverages) by renowned experts in their particular fields from the United States, Europe, and Japan present a wealth of food and beverage stability information in handbook format. In particular, the chapters on fish and shellfish, cheese, and meat are remarkable in presenting data not readily available in an easily digestible form.****This handbook, encompassing as it does aging, shelf life, and stability--in short, the knowledge necessary to ensure preservation of our food supply--should help to bring about the above-mentioned synergism between chemical, agricultural, and related sciences. It is expected to fill a need, especially through the convenience of its tabular presentations.

    The ultimate motivation for the study which is the subject of this book was the need to draw conclusions on the impact of man's activity on natural ecosystems. The results characterize the situation of the south-Moravian floodplain forest in the period of fading uncontrolled floods before the extensive technical measures successively changed the moisture regime by eliminating inundation and lowering the level of underground water. This publication is unique in Czechoslovakia as it records the ecological situation in the floodplain forest prior to the major and irreversible changes. The study also documents the exceptional role played by the Central-European floodplain forest in maintaining the gene pool and structure of the one thousand or so species in flora and fauna of an agricultural region.

    Plant Growth and Development: A Molecular Approach presents the field of plant development from both molecular and genetic perspectives. This field has evolved at a rapid rate over the past five years through the increasing exploitation of the remarkable plant Arabidopsis. The small genome, rapid life cycle, and ease of transformation of Arabidopsis, as well as the relatively large number of laboratories that are using this plant for their research, have lead to an exponential increase in information about plant development mechanisms.In Plant Growth and Development: A Molecular Approach Professor Fosket synthesizes this flood of new information in a way that conveys to students the excitement of this still growing field. His textbook is based on notes developed over more than ten years of teaching a course on the molecular analysis of plant growth and development and assumes no special knowledge of plant biology. It is intended for advanced undergraduates in plant development, as well as those in plant molecular biology. Graduate students and researchers who are just beginning to work in the field will also find much valuable information in this book. Each chapter concludes with questions for study and review as well as suggestions for further reading. Illustrated with two-color drawings and graphs throughout, and containing up-to-date and comprehensive coverage, Plant Growth and Development: A Molecular Approach will excite and inform students as it increases their understanding of plant science.
