Agrometeorology

Category : Technology & Engineering
Languages : en
Pages : 333

Book Description
Agrometeorology is a comparatively young science. The beginnings of agrometeorological work came in the 20's of this century, when agrometeorology was a working branch of climatology. In the years following 1950 it then developed widely to an independent science. In this process, agrome teorology has not only gained a vast knowledge of the influence of meteorological conditions on plants and livestock in agriculture and damage prevention, but additionally evolved new advisory methods which are of great practical use in agriculture. Up to the present time there has been practically no specific training for an agrometeorologist. Agrometeoro logists are drawn, according to their training, from the ranks of general meteorology or from agriculture and its related biological disciplines. They must, therefore, them selves gather the knowledge for their agrometeorological work and combine for themselves the complex of agrome teorology from biological and meteorological information. This is usuaIIy far from easy, as the relevant literature is scattered among the most widely differing journals, partly in little-known foreign languages, and is thus very difficult of access. Comprehensive writings are to be found only in very few partial fields of agrometeorology. The subject of training problems has thus been treated as of utmost importance at the meetings ofthe Commission for Agrometeorology (CAgM) of the World Meteorological Organization (WMO), especially as agrometeorology has won such great significance and useful ness not only in the so-called underdeveloped countries in advancing a more productive agriculture, but also in coun tries whose agricultural standard is already high.

Adverse Reproductive Outcomes in Families of Atomic Veterans

Author: Institute of Medicine
Publisher: National Academies Press
ISBN: 0309176115
Category : Medical
Languages : en
Pages : 107

Book Description
Over the past several decades, public concern over exposure to ionizing radiation has increased. This concern has manifested itself in different ways depending on the perception of risk to different individuals and different groups and the circumstances of their exposure. One such group are those U.S. servicemen (the "Atomic Veterans" who participated in the atmospheric testing of nuclear weapons at the Nevada Test Site or in the Pacific Proving Grounds, who served with occupation forces in or near Hiroshima and Nagasaki, or who were prisoners of war in or near those cities at the time of, or shortly after, the atomic bombings. This book addresses the feasibility of conducting an epidemiologic study to determine if there is an increased risk of adverse reproductive outcomes in the spouses, children, and grandchildren of the Atomic Veterans.

Biologic Effects of Light 2001

Pages : 530

Book Description
As humans ventured into the twentieth century, the industrialized countries were confronted with the scourge of rickets. Although solariums were becoming common in the early 1900s and phototherapy was gaining popularity as a result of the awarding of a Nobel Prize to Finsen in 1903, it wasn't until 1921 when Hess and Unger demonstrated that rickets could be cured by exposure to sunlight that the healthful benefit of sun exposure appreciated. In 1941, Apperly (Cancer Research; 1: 191-195, 1941) noted that the occasional increased risk of skin cancer was associated with a decreased risk of many other more common and serious cancers. The alarming increase in the number of cases of skin cancer, especially melanoma, has caused great concern about the negative role of sunlight in health. The Sixth International Arnold Rikli Symposium on the Biologic Effects of Light was held in Boston, Massachusetts from June 16th - 18th, 2001. The goal of this Symposium was to focus on the very popular practice of tanning either by sunlight or by artificial light sources and the overall impact this practice has on health and disease. The program was organized by members of the Scientific Advisory Committee and my co-chair emeritus, Professor Ernst G. Jung. The Program Committee organized an outstanding state-of-the-art program that was enthusiastically received by the participants.

Ecological Consequences of Artificial Night Lighting

Author: Catherine Rich
Publisher: Island Press
ISBN: 1597265969
Category : Nature
Languages : en
Pages : 480

Book Description
While certain ecological problems associated with artificial night lighting are widely known-for instance, the disorientation of sea turtle hatchlings by beachfront lighting-the vast range of influences on all types of animals and plants is only beginning to be recognized. From nest choice and breeding success of birds to behavioral and physiological changes in salamanders, many organisms are seriously affected by human alterations in natural patterns of light and dark. Ecological Consequences of Artificial Night Lighting is the first book to consider the environmental effects of the intentional illumination of the night. It brings together leading scientists from around the world to review the state of knowledge on the subject and to describe specific effects that have been observed across a full range of taxonomic groups, including mammals, birds, reptiles and amphibians, fishes, invertebrates, and plants. Ecological Consequences of Artificial Night Lighting provides a scientific basis to begin addressing the challenge of conserving the nighttime environment. It cogently demonstrates the vital importance of this until-now neglected topic and is an essential new work for conservation planners, researchers, and anyone concerned with human impacts on the natural world.

Health Effects of Exposure to Low Levels of Ionizing Radiation

Author: National Research Council
Publisher: National Academies
ISBN: 0309039959
Category : Science
Languages : en
Pages : 436

Book Description
This book reevaluates the health risks of ionizing radiation in light of data that have become available since the 1980 report on this subject was published. The data include new, much more reliable dose estimates for the A-bomb survivors, the results of an additional 14 years of follow-up of the survivors for cancer mortality, recent results of follow-up studies of persons irradiated for medical purposes, and results of relevant experiments with laboratory animals and cultured cells. It analyzes the data in terms of risk estimates for specific organs in relation to dose and time after exposure, and compares radiation effects between Japanese and Western populations.

Languages : en
Pages : 622

Book Description
University Physics is a three-volume collection that meets the scope and sequence requirements for two- and three-semester calculus-based physics courses. Volume 1 covers mechanics, sound, oscillations, and waves. Volume 2 covers thermodynamics, electricity and magnetism, and Volume 3 covers optics and modern physics. This textbook emphasizes connections between between theory and application, making physics concepts interesting and accessible to students while maintaining the mathematical rigor inherent in the subject. Frequent, strong examples focus on how to approach a problem, how to work with the equations, and how to check and generalize the result. The text and images in this textbook are grayscale.

Biological Effects of Ultraviolet Radiation

Author: Walter Harm
Publisher: Cambridge University Press
ISBN: 9780521293624
Category : Science
Languages : en
Pages : 234

Book Description
Originally published in 1980, this book examines the effects of ultraviolet radiation on the genetic material of cells and the repair mechanisms by which many cells can reverse the damage caused by UV. The work was intended to be a combination textbook/introductory monograph for graduate and advanced undergraduate students in photobiology, biophysics, microbiology, and genetics. It was the first volume in an introductory series on topics in biophysics sponsored by the International Union of Pure and Applied Biophysics.
