Available in PDF, EPUB and Kindle. Book excerpt: The Kjeldahl Method for Organic Nitrogen volume presents a broad and comprehensive survey of the method as applied to natural products and organic nitrogen compounds. The quantitative determination of an element as widely distributed as nitrogen is of great importance, and the truth of this is borne out by the tremendous amount of literature published throughout the years. The analysis of nitrogen can be divided into two classes: inorganic and organic. This book is concerned only with organic nitrogen compounds, and specifically their determination by the Kjeldahl method. The book opens with a chapter on the historical background and the work leading to the evolution of the method. This is followed by separate chapters that discuss each of the several divisions of the method, e.g., salt addition, reduction, oxidation, catalysts, distillation.

Book excerpt: Of all the advances in agriculture, it is the use of nitrogen fertilizers that has provided the greatest increase in crop yield. The study of nitrogen metabolism is thus of vital importance. Additionally, because nitrogen is a constituent of such a wide range of plant metabolites, the study of their chemistry and biochemistry engages the attention of many plant scientists. This book covers recent developments in this field. Topics include the study of root nodules; the uptake, assimilation, and transport of ammonium and nitrate; amino acid metabolism; the distribution and synthesis of seed proteins; and recent research on polyamines, cyanogenic glycosides, and alkaloids. There are also chapters on denitrification and the impact of nitrogen on agricultural productivity and the environment. With contributions from international experts, this volume will interest all plant physiologists and phytochemists as well as biochemists interested in the behavior of nitrogen compounds.

Book excerpt: Semimicro Quantitative Organic Analysis focuses on the analytical phase of research and chemistry of natural products, as well as analysis of gases and methods used in identifying iodine and other substances. The manuscript first offers information on the determination of carbon, hydrogen, and nitrogen, and the use of Kjeldahl and Dumas methods in the determination of nitrogen. The book also ponders on the determination of halogens, including the use of ethanolamine-sodium, Carius, and sodium peroxide fusion methods and the Liepert volumetric method for iodine. The publication discusses the determination of sulfur and phosphorus, as well as the alkali-nitrate fusion method for converting organic phosphorus to orthophosphate and Woy's procedure for weighing phosphorus as phosphomolybdic anhydride. The text also reviews the determination of methoxyl and ethoxyl and acetyl groups; determination of neutralization equivalent and molecular weights; and determination of volatile fatty acids. The manuscript is a dependable reference for readers interested in the chemistry of natural products.

Available in PDF, EPUB and Kindle. Book excerpt: 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 ex isting and the introduction of new methods; 2. the difficulty in finding many new analytical methods in specialized jour nals 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 so compact, or even sometimes so incomplete that it is dif ficult to reproduce experiments. These considerations still stand today. The series was highly successful, seven volumes appearing between 1956 and 1964. Since there is still today a demand for the old series, the publisher has decided to resume publication of Modern Methods of Plant Analysis. It is hoped that the New Series will be just as acceptable to those working in plant sciences and related fields as the early volumes undoubtedly were. It is difficult to single out the major reasons for success of any publication, but we believe that the methods published in the first series were up-to-date at the time and presented in a way that made description, as applied to plant material, com plete in itself with little need to consult other publications. Contribution authors have attempted to follow these guidelines in this New Series of volumes.

Book excerpt: River Pollution 1: Chemical Analysis discusses methods of detecting and determining the various forms of pollution and the interpretation of results. It aims to provide a chemical background for, and supplement to, the information on analytical methods, and to review critically other methods which may be useful in certain circumstances for research, control work, and field tests. The book begins with a description of river surveys, and physical and chemical methods for determining river pollution. Separate chapters cover methods to determine the presence of dissolved oxygen, combined nitrogen, sulfur compounds, carbon dioxide, free chlorine, metallic contaminants, and carbon compounds. Subsequent chapters discuss the estimation of less important substances which may sometimes be encountered in pollution problems; and the significance of chemical and physical tests and the interpretation of the results of an analysis. This book is intended for those interested in chemical analysis as applied to river pollution problems, sewage, and trade wastes.

This book was released on 2023-06-28 with total page 179 pages. Available in PDF, EPUB and Kindle. Book excerpt: High-throughput technologies are those that allow the generation of large-scale data related to omic analysis (such as genomics, transcriptomics, proteomics, phenomics, and metabolomics). Currently, the development and use of these technologies has gone hand-in-hand with the development of bioinformatics tools, which have allowed the integration of omics-based data to understand crucial knowledge about the molecular systems that underlie the various functions of the plants. In recent years, there has been a huge development in the field of high-throughput biology, which is attributed to an era of tech startups. Genomics studies in plants, for instance, have benefited from advances in high-throughput technologies, such as high-throughput genotyping, which have allowed us to investigate the regulation and function of thousands of genes and genomic regions involved in a novel adaptation. In fact, with current high-throughput technologies, it is possible to recover substantial portions of the plant diversity, which is a key input for genetic improvement programs, food security and conservation programs. The integration of multilevel biological data, involving investigations at the molecular level (in genomics, transcriptomics, proteomics, and metabolomics, among others), have allowed more comprehensive studies, which broadens the opportunities to clarify key molecular aspects involved in the physiological responses to abiotic stresses.

Available in PDF, EPUB and Kindle. Book excerpt: Since the book first appeared in 1976, Methods of Seawater Analysis has found widespread acceptance as a reliable and detailed source of information. Its second extended and revised edition published in 1983 reflected the rapid pace of instrumental and methodological evolution in the preceding years. The development has lost nothing of its momentum, and many methods and procedures still suffering their teething troubles then have now matured into dependable tools for the analyst. This is especially evident for trace and ultra-trace analyses of organic and inorganic seawater constituents which have diversified considerably and now require more space for their description than before. Methods to determine volatile halocarbons, dimethyl sulphide, photosynthetic pigments and natural radioactive tracers have been added as well as applications of X-ray fluorescence spectroscopy and various electrochemical methods for trace metal analysis. Another method not previously described deals with the determination of the partial pressure of carbon dioxide as part of standardised procedures to describe the marine CO2 system.

This book was released on 2012-12-06 with total page 414 pages. Available in PDF, EPUB and Kindle. Book excerpt: The large and rapidly expanding body ofliterature related to nitrogen cycling in both managed and native terrestrial ecosystems reflects the importance accorded to the behaviour of this vital and often limiting nutrient. Research at the organism, ecosystem and landscape levels commonly addresses questions concerning nitrogen acquisition, internal cycling and retention. Goals for this research include increased agricultural productivity and a better understanding of human impact on local, regional and global nitrogen cycles. Nitrogen cycle research in tropical regions has a long and distinguished history. Research on different aspects of nitrogen cycling in ecosystems of the tropics has been carried out in many regions. In relatively few instances has there, however, been a focus on the biogeochemical cycles at the ecosystem level. The meeting resulting in this volume was an attempt to bring together existing information on nitrogen cycling in ecosystems of Latin America and the Caribbean and discuss this in an ecosystem context.
