Book Description
The bibi iograp hy includes papers in a l I fields of photosynthesis research - from stu dies of model biochemical and biophysical systems of t he photosynt hes is mechanism to primary prod ucti on studied by t he so-ca Ile d growth analysis . In addition to papers devoted enti rel y to photosynth es is, papers on other topics are inc luded if t hey con t ai n data on photosynthetic activity, photorespiration, chloroplast structure, chlo rophylland carotenoid synthesi s and destruction, eta., or if they conta in valuable methodological information (measurement of selected environmentaI factars, leaf area, eta.) . In many branches it has been difficult to defi ne th e limits of int erest for photosynthesis researchers. This problem has arisen e. g. in topics deal ing with t he transfer of gases, where - in addition to t he papers on ca rbon dioxide transfe r - so me pape rs on water vapour transfer are included, these being of general appl icat ion or bringing new approaches . On th e other hand, m any papers deal ing wit h the anatomy and phys io logy of stomata have been omitted, if the aspect of ca rbon dioxide or water vapour exchange has not been discussed.

Book Description
The Biochemistry of Plants: A Comprehensive Treatise, Volume 8: Photosynthesis provides information pertinent to the biochemistry of photosynthesis. This book focuses on the photosynthesis of higher plants but some consideration is given to algal and bacterial photosynthesis. Organized into 11 chapters, this volume begins with an overview of the excitation of a light-harvesting pigment by an absorbed light quantum. This text then discusses the evidence to support the hypothesis that chlorophyll–protein complexes are represented at the supramolecular level by some of the intramembranous particles seen on chloroplast freeze-fracture faces. Other chapters consider the absorption of light energy by accessory pigments and transferred to chlorophyll in the blue-green, red, and brown algae. This book discusses as well that certain cyanobacteria respond to the color of the incident light by altering their biliprotein composition. The final chapter deals with dark reaction of photosynthesis. This book is a valuable resource for plant biochemists, neurobiochemists, molecular biologists, senior graduate students, and research workers.

Book Description
Since 1963 the Research Materials Information Center has been answering inquiries on the availability, preparation, and properties of ultrapure inorganic research specimens. It has been possible to do this with reasonable efficiency by searching an automated coded microfilm collection of the report and open literature and of data sheets and question naires provided by commercial and research producers of pure materials. With the growth of the collection to over 70,000 documents and the increase in the demand for more general background information, it has been necessary to compile bibliographies on an increasing variety of subjects. These have been used as indexes to the microfilmed documents for more efficient searching, and in the past distributed in response to individual requests. However, their size and number no longer permit so casual and uneconomic a method of distribution. The "ORNL Solid State Physics Literature Guides" is a practical alternative. Organization The subject organization of the bibliography is given by the Table of Contents. Each section is preceded by a collection of reviews, bibliographies, and "general" papers (i.e., those dealing with methods or equipment rather than single materials, or with such a wide variety of materials that no subsection was appropriate). Coverage is generally from 1960 to mid-1970. Emphasis is on inorganic materials.

Book Description
More than ten years ago, the first genetically modified foods took their place on the shelves of American supermarkets. But while American consumers remained blissfully unconcerned with the new products that suddenly filled their kitchens, Europeans were much more wary of these “Frankenfoods.” When famine struck Africa in 2002, several nations refused shipments of genetically modified foods, fueling a controversy that put the issue on the world's political agenda for good. In Food Fray, esteemed molecular biologist Dr. Lisa H. Weasel brings readers into the center of this debate, capturing the real-life experiences of the scientists, farmers, policymakers and grassroots activists on the front lines. Here she combines solid scientific knowledge and a gripping narrative to tell the real story behind the headlines and the hype. Seminal and cutting-edge, Food Fray enlightens and informs and will allow readers to make up their own minds about one of the most important issues facing us today.

Book Description
Modeling Uncertainty in the Earth Sciences highlights the various issues, techniques and practical modeling tools available for modeling the uncertainty of complex Earth systems and the impact that it has on practical situations. The aim of the book is to provide an introductory overview which covers a broad range of tried-and-tested tools. Descriptions of concepts, philosophies, challenges, methodologies and workflows give the reader an understanding of the best way to make decisions under uncertainty for Earth Science problems. The book covers key issues such as: Spatial and time aspect; large complexity and dimensionality; computation power; costs of 'engineering' the Earth; uncertainty in the modeling and decision process. Focusing on reliable and practical methods this book provides an invaluable primer for the complex area of decision making with uncertainty in the Earth Sciences.
