Book Description
This collection discusses the variety of specific molecular reactions by means of which plants respond to physiological and toxic stress conditions. It focuses on the characterization of the molecular mechanisms that underlie the induction of toxicity and the triggered responses and resistances. The nine chapters, all written by prominent researchers, examine heavy metal toxicity, aluminum toxicity, arsenic toxicity, salt toxicity, drought stress, light stress, temperature stress, flood stress and UV-B stress. In addition, information on the fundamentals of stress responses and resistance mechanisms is provided. The book addresses researchers and students working in the fields of plant physiology and biochemistry.​

Book Description
A NATO Advanced Study Institute on "Light as Energy Source and Information Carrier in Plant Photo physiology" was held at Volterra, Italy, from September 26 to October 6, 1994, in order to consider the fundamental role that light plays in plant growth and development. This book summarises the main lectures given at this meeting which concentrated on both photochemical energy conversion and signalling (photosensing) aspects. Light harvesting and conversion into chemical energy in photosynthesis occurs at the level of chlorophyll/carotenoid containing photosystems in plants. Pigments are non covalently bound to a variety of polypeptides which serve as a specific scaffolding, necessary to determine the energy coupling between pigments and thus allowing rapid excitation energy trasfer from the antenna to the special reaction centre chlorophylls. Data from transient, time resolved spectroscopies, in the femtosecond and picosecond domain, together with model calculations, suggest that this process occurs in the 20-100 picosecond time span. The special ~ll u~ture of reaction centre complexes, ensures rapid primary charge separation, probably in the order of 1-3 picoseconds, with subsequent charge stabilisation reactions proceeding in the hundreds of picoseconds range. The recently resolved crystallographic structure of LHCII, the principal antenna complex of plants, allows precise determination of pigment-pigment distances and thus permits calculation of approximate chlorophyll-chlorophyll Forster hopping rates, which are in good agreement with time resolved measurements.

Book Description
Wastewater Microbiology focuses on microbial contaminants found in wastewater, methods of detection for these contaminants, and methods of cleansing water of microbial contamination. This classic reference has now been updated to focus more exclusively on issues particular to wastewater, with new information on fecal contamination and new molecular methods. The book features new methods to determine cell viability/activity in environmental samples; a new section on bacterial spores as indicators; new information covering disinfection byproducts, UV disinfection, and photoreactivation; and much more. A PowerPoint of figures from the book is available at ftp://ftp.wiley.com/public/sci_tech_med/wastewater_microbiology.

Book Description
During the past few decades we have witnessed an era of remarkable growth in the field of molecular biology. In 1950 very little was known ofthe chemical constitution of biological systems, the manner in which information was transmitted from one organism to another, or the extent to which the chemical basis of life is unified. The picture today is dramatically different. We have an almost bewildering variety of information detailing many different aspects oflife at the molecular level. These great advances have brought with them some breath-taking insights into the molecular mechanisms used by nature for replicating, distributing and modifying biological information. We have learned a great deal about the chemical and physical nature of the macro molecular nucleic acids and proteins, and the manner in which carbohydrates, lipids and smaller molecules work together to provide the molecular setting of living systems. It might be said that these few decades have replaced a near vacuum of informa tion with a very large surplus. It is in the context of this flood of information that this series of monographs on molecular biology has been organized. The idea is to bring together in one place, between the covers of one book, a concise assessment of the state of the subject in a well-defined field. This will enable the reader to get a sense of historical perspective what is known about the field today - and a description of the frontiers of research where our knowledge is increasing steadily.

Book Description
"Leben ist die schonste Erfindung der Natur und der Tod ist ihr Kunstgriff, viel Leben zu haben" . J. W. v. Goethe Life is the most beautiful invention of nature, and death is her device to exhibit most life. The eminent British biologist Sir Vincent B. Wigglesworth noted in 1939 that insects are an ideal medium in which to study all problems of physiology. Many fundamental discoveries in biology, particularly genetics and development, have been made on the basis of studies conducted in insects. Because of their ex treme adaptability and diversity, an appropriate insect model is available for the study of virtually any biological problems. The applicability to other groups, including mammals, of basic studies conducted on insects has helped in the gradual acceptance of the fundamental unity of biochemical principles as a dogma among biologists, as well as among enlightened medical scientists. With the recent upsurge of interest in the study of the aging process, in sects have been increasingly employed not only for the investigation of basic mechanisms of aging, but also to gain insight into the evolution of aging and senescence. If only one aging mechanism exists, it is foreseeable that some in sects, especially Drosophila, will help to unravel its molecular basis. Because of their diversity, existing studies in the gerontology of insects are widely scat tered in various specialized journals. This wealth of existing information has not, as yet, been brought together in a synthesized and comprehensive form.
