Se analiza cómo la temperatura, la radiación, las características de los suelos, las aguas de riego y el manejo que realizan los agricultores determinan el rendimiento del arroz. El objetivo fue conocer el sistema de producción arroz en Entre Ríos y determinar cuales son los factores más importantes que limitan el crecimiento y la productividad del cultivo; identificando la brecha entre el rendimiento actual y potencial a nivel de campo. Luego de un capítulo introductorio donde se presentan las generalidades del cultivo de arroz en Argentina, los fundamentos, los objetivos e hipótesis de la investigación realizada; en el Capítulo II, se describe el medio físico y las características del área de estudio, así como los aspectos de la fisiología y la genética del arroz. En el Capítulo III se presentan en detalle los materiales y métodos empleados. Se trata de 180 observaciones en campos de agricultores, durante 4 años, donde se evaluaron variables de suelo, clima, agua, manejo, estructura del cultivo, absorción de nutrientes. Más de 80 variables fueron analizadas estadísticamente y mediante un proceso lógico deductivo, que tiende a identificar los factores que determinan el rendimiento. El Capítulo IV muestra los resultados presentando los distintos factores en forma individual. Se analizó el efecto de las temperaturas extremas (frío y calor) sobre el rendimiento y de las temperaturas medias sobre la duración de los períodos fenológicos. Se estimó el rendimiento potencial para Entre Ríos en 14 Mg/ha, siendo la producción media de 7 Mg/ha y habiéndose registrado un máximo de 13,7 Mg/ha en ensayos experimentales. Con la genética disponible existe una brecha explorable de 3 Mg/ha ente el rendimiento actual y el alcanzable. Los componentes del cultivo más importantes fueron el número de panojas por unidad de superficie y el número de granos llenos por panoja.

Book excerpt: This publication deals with key issues in land tenure, especially as they relate to food insecurity and rural development situations. Land tenure issues are frequently ignored in rural development interventions, with often long-lasting, negative results. This guide is designed to assist technical officers in governments and civil society in understanding why and how land tenure issues should be considered in rural development projects. It analyses important contexts such as environmental degradation, gender discrimination, and conflicts, where land tenure is currently of critical concern.

Available in PDF, EPUB and Kindle. Book excerpt: Soil and Sediment Remediation discusses in detail a whole set of remediative technologies currently available to minimise their impact. Technologies for the treatment of soils and sediments in-situ (landfarming, bioscreens, bioventing, nutrient injection, phytoremediation) and ex-situ (landfarming, bio-heap treatment, soil suspension reactor) will be discussed. The microbiological, process technological and socio-economical aspects of these technologies will be addressed. Special attention will be given to novel biotechnological processes that utilise sulfur cycle conversions, e.g. sulfur and heavy metal removal from soils. Also the potential of phytoremediation will be highlighted. In addition, treatment schemes for the clean-up of polluted megasites, e.g. harbours and Manufactured Gaswork Plants (MGP), will be elaborated. The aim of Soil and Sediment Remediation is to introduce the reader in: the biogeochemical characteristics of soil and sediments- new techniques to study soil/sediment processes (molecular probes, microelectrodes, NMR) clean up technologies for soils polluted with organic (PAH, NAPL, solvents) or inorganic (heavy metals) pollutants- preventative and remediative strategies and technologies available in environmental engineering novel process applications and bioreactor designs for bioremediation the impact of soil pollution on society and its economic importance.

Book excerpt: In the second edition of Biometricai Genetics, which appeared in 1971, we set out to give a general account of the subject as it had developed up to that time. Such an account necessarily had to be comprehensive and reasonably detailed. Although it could be, and indeed has been, used by those who were making an acquaintance with this branch of genetics for the first time, it went beyond their needs. We have been encouraged therefore to write an introduction to the genetical analysis of continuous variation aimed primarily at senior undergraduate and postgraduate students, and concentrating on basic considerations, basic principles and basic techniques. This has meant, of course, omitting all reference to some phenomena of more restricted interest, notably sex-linkage, ma ternal effects, haploidy and polyploidy. It has meant, too, that even with some phenomena which have been included, like interactions, linkage and effective factors, the discussions cannot go into full detail. Anyone who is interested, however, can find further information in Biometricai Genetics, to which detailed references have been given where it ap peared that these would be helpful. The order of presentation has been changed with the aim of making it easier for beginners.

This book was released on 2010 with total page 728 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report considers the biological and behavioral mechanisms that may underlie the pathogenicity of tobacco smoke. Many Surgeon General's reports have considered research findings on mechanisms in assessing the biological plausibility of associations observed in epidemiologic studies. Mechanisms of disease are important because they may provide plausibility, which is one of the guideline criteria for assessing evidence on causation. This report specifically reviews the evidence on the potential mechanisms by which smoking causes diseases and considers whether a mechanism is likely to be operative in the production of human disease by tobacco smoke. This evidence is relevant to understanding how smoking causes disease, to identifying those who may be particularly susceptible, and to assessing the potential risks of tobacco products.

Available in PDF, EPUB and Kindle. Book excerpt: When WILHELM RUHLAND developed his plan for an Encyclopedia of Plant Physiol ogy more than three decades ago, biology could still be conveniently subdivided into classical areas. Even within plant physiology, subdivisions were not too difficult to make, and general principles could be covered sufficiently in the two introductory volumes of the Encyclopedia on the physical and chemical basis of cell biology. But the situation changed rapidly even during the 12-year publication period of the Encyclopedia (1955-1967). The new molecular direction of genetics and structural research on biopolymers had an integrating effect on all other biological fields, including plant physiology, and it became increasingly difficult to keep previously distinct areas separated. RUHLAND'S overall plan included 18 volumes and about 22,000 pages. It covered the entire field of plant physiology, in most cases from the very beginning. But, as each volume appeared, it was clear that its content would soon be outdated.

Book excerpt: Tropical Stream Ecology describes the main features of tropical streams and their ecology. It covers the major physico-chemical features, important processes such as primary production and organic-matter transformation, as well as the main groups of consumers: invertebrates, fishes and other vertebrates. Information on concepts and paradigms developed in north-temperate latitudes and how they do not match the reality of ecosystems further south is expertly addressed. The pressing matter of conservation of tropical streams and their biodiversity is included in almost every chapter, with a final chapter providing a synthesis on conservation issues. For the first time, Tropical Stream Ecology places an important emphasis on viewing research carried out in contributions from international literature. - First synthetic account of the ecology of all types of tropical streams - Covers all of the major tropical regions - Detailed consideration of possible fundamental differences between tropical and temperate stream ecosystems - Threats faced by tropical stream ecosystems and possible conservation actions - Descriptions and synstheses life-histories and breeding patterns of major aquatic consumers (fishes, invertebrates)
