Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this handbook is to provide members of the Forest Service with conversion factors and forest measurements that are more or less frequently encountered in forest literature. These are expressed in tabular form where it appears most advantageous to do so; in the other cases a series of alignment charts have been prepared, which permit the direct determination of values in multiple form. There are included also certain other tables giving data more or less commonly used in forest calculations.

Download or read book Mineral Salts Absorption in Plants written by J. F. Sutcliffe and published by Elsevier. This book was released on 2013-10-22 with total page 209 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mineral Salts Absorption in Plants details the contemporary knowledge regarding the mineral salt absorption mechanisms of plants. The title first covers the history of mineral salt absorption in plants, and then proceeds to tackling the experimental materials and methods. Next, the selection discusses the mechanisms of ion transport. Chapter 4 deals with the factors affecting salt absorption, while Chapter 5 talks about salt absorption and metabolisms. In the sixth chapter, the text covers the structural aspects of salt absorption in cells. The seventh chapter discusses the salts relations of vascular plants. The selection also talks about the soil as a source of mineral salts, along with salt tolerance. The book will be of great use to botanists and horticulturists. Students and researchers in the field of mineral nutrition will also benefit from the text.

Download or read book Physiological Plant Ecology II written by Otto L. Lange and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 747 pages. Available in PDF, EPUB and Kindle. Book excerpt: O. L. LANGE, P. S. NOBEL, C. B. OSMOND, and H. ZIEGLER In the original series of the Encyclopedia of Plant Physiology, plant water relations and photosynthesis were treated separately, and the connection between phenomena was only considered in special chapters. O. STOCKER edited Vol ume III, Pjlanze und Wasser/Water Relations of Plants in 1956, and 4 years later, Volume V, Parts I and 2, Die COrAssimilation/The Assimilation of Carbon Dioxide appeared, edited by A. PIRSON. Until recently, there has also been a tendency to cover these aspects of plant physiology separately in most text books. Without doubt, this separation is justifiable. If one is specifically inter ested, for example in photosynthetic electron transport, in details of photophos phorylation, or in carbon metabolism in the Calvin cycle, it is not necessary to ask how these processes relate to the water relations of the plant. Accordingly, this separate coverage has been maintained in the New Series of the Encyclopedia of Plant Physiology. The two volumes devoted exclusively to photosynthesis are Volume 5, Photosynthesis I, edited by A. TREBST and M. AVRON, and Volume 6, Photosynthesis II, edited by M. GIBBS and E. LATZKO. When consider ing carbon assimilation and plant water relations from an ecological point of view, however, we have to recognize that this separation is arbitrary.

This book was released on 2012-12-06 with total page 167 pages. Available in PDF, EPUB and Kindle. Book excerpt: Residues of pesticides and other "foreign" chemicals in foodstuffs are of concern to everyone everywhere; they are essential to food production and manufacture, yet without surveillance and intelligent control some of those that persist could at times conceivably endanger the public health. The object of "Residue Reviews" is to provide concise, critical reviews of timely advances, philosophy, and significant areas of accomplished or needed endeavor in the total field of residues of thes. e chemicals in foods, in feeds, and in transformed food products. These reviews are either general or specific, but properly they may lie in the domains of analytical chemistry and its methodology, biochemistry, human and animal medicine, legislation, pharmacology, physiology, regulation, and toxicology; certain a:ffairs in the realm of food technology that are concerned specifically with pesticide and other food-additive problems are also appropriate subject matter. The justification for the preparation of any review for this book series is that it deals with some aspect of the many real problems arising from the presence of residues of foreign chemicals in foodstuffs. The scope of "Residue Reviews" is international. It encompasses those matters, in any country, which are involved in allowing pesticide and other plant-protecting chemicals to be used safely in producing, storing, and shipping crops. Added plant or animal pest-control chemicals or their metabolites that may persist into' meat and other edible animal products (milk and milk products, eggs, etc.
