Download or read book Seasonal Variations in Light Scattering in the New York Region and Their Relation to Sources written by and published by . This book was released on 1980 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Light scattering data collected during two periods of intensive sampling in New York City (one during summer months and one during winter months) are discussed and analyzed for diurnal patterns, their relationship to pollutant emission sources, meteorological parameters, and the size distribution and chemical composition of the ambient aerosol. The lack of a diurnal pattern for light scattering in summer in combination with a strong positive association with ozone and wind direction dependency suggests that in summer the transport of an aged aerosol in photochemically rich air masses rather than local emissions of primary pollutants is largely responsible for the observed levels of light scattering in New York City. Winter levels of light scattering observed in New York City, while approximately 50% lower than summer levels, were much less dependent on wind direction and closely related to pollutant emissions from local sources. This suggests that locally generated aerosol dominates light scattering in the winter. Particles 0.1.mu.m to 1.3.mu.m in diameter were strongly correlated with light scattering in New York City during both summer and winter periods. However, a given volume of aerosol between 0.1.mu.m and 1.3.mu.m scattered more light in summer than in winter, indicating the fresher nature of the winter aerosol. Variance in dry particulate light scattering was found to principally account for light extinction variance (calculated from airport visibility observations) in summer and winter. Sulfate aerosol was strongly correlated with light scattering during both summer and winter periods.
Download or read book Watershed Management for Potable Water Supply written by National Research Council and published by National Academies Press. This book was released on 2000-02-17 with total page 569 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1997, New York City adopted a mammoth watershed agreement to protect its drinking water and avoid filtration of its large upstate surface water supply. Shortly thereafter, the NRC began an analysis of the agreement's scientific validity. The resulting book finds New York City's watershed agreement to be a good template for proactive watershed management that, if properly implemented, will maintain high water quality. However, it cautions that the agreement is not a guarantee of permanent filtration avoidance because of changing regulations, uncertainties regarding pollution sources, advances in treatment technologies, and natural variations in watershed conditions. The book recommends that New York City place its highest priority on pathogenic microorganisms in the watershed and direct its resources toward improving methods for detecting pathogens, understanding pathogen transport and fate, and demonstrating that best management practices will remove pathogens. Other recommendations, which are broadly applicable to surface water supplies across the country, target buffer zones, stormwater management, water quality monitoring, and effluent trading.

Available in PDF, EPUB and Kindle. Book excerpt: "Among the crucial problems that confront mankind today are those associated with a degraded environment. This book examines the extent to which warfare and other military activities contribute to such degradation. The military capability to damage the environment and to cause ecological disruption has escalated, and there is no sign that the level of conflict in the world is decreasing. The military use and abuse of each of the several major global habitats -- temperate, tropical, desert, arctic, insular, and oceanic -- are evalusated separately in the light of the civil use and abuse of that habitat"--Dust jacket.

Download or read book The Great Riots of New York 1712 to 1873 written by J. T. Headley and published by Cosimo Classics. This book was released on 1873 with total page 380 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the most popular writers of his day-and one most unjustly forgotten-J.T. Headley thrilled audiences with his tales of real-life history. This 1873 work is an enthralling collection of accounts of urban upheaval in one of the U.S.'s most historically vital cities: New York. Here, Headley offers us highly readable and informative reports on: - the negro riots of 1712-1741 - the Stamp Act riot of 1765 - the doctors' riot of 1788 - the abolition riots 1834-5 - the flour riot of 1837 - the draft riots of 1863 - and more. Anyone interested in the history of New York City will find this a fascinating read. American writer and journalist JOEL TYLER HEADLEY (1813-1897) was an editor at the *New York Tribune* and wrote extensively on historical matters. Among his many books are *Washington and His Generals* (1847), *Life of Cromwell* (1848), and the bestselling *Life of Washington* (1857).

Download or read book The Cerrados of Brazil written by Paulo S. and published by Columbia University Press. This book was released on 2013-02-05 with total page 409 pages. Available in PDF, EPUB and Kindle. Book excerpt: The massive grasslands of Brazil -- known as the cerrados -- which cover roughly a quarter of its land surface and are among the most threatened regions in South America, have received little media attention. This book brings together leading researchers on the area to produce the first detailed account in English of the natural history and ecology of the cerrado/savanna ecosystem. Given their extent and threatened status, the richness of their flora and fauna, and the lack of familiarity with their unique ecology at the international level, the cerrados are badly in need of this important and timely work.
Download or read book Risk Assessment Methods written by V.T. Covello and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: Much has already been written about risk assessment. Epidemiologists write books on how risk assessment is used to explore the factors that influence the distribution of disease in populations of people. Toxicologists write books on how risk assess ment involves exposing animals to risk agents and concluding from the results what risks people might experience if similarly exposed. Engineers write books on how risk assessment is utilized to estimate the risks of constructing a new facility such as a nuclear power plant. Statisticians write books on how risk assessment may be used to analyze mortality or accident data to determine risks. There are already many books on risk assessment-the trouble is that they all seem to be about different sUbjects! This book takes another approach. It brings together all the methods for assessing risk into a common framework, thus demonstrating how the various methods relate to one another. This produces four important benefits: • First, it provides a comprehensive reference for risk assessment. This one source offers readers concise explanations of the many methods currently available for describing and quantifying diverse types of risks. • Second, it consistently evaluates and compares available risk assessment methods and identifies their specific strengths and limitations. Understand ing the limitations of risk assessment methods is important. The field is still in its infancy, and the problems with available methods are disappoint ingly numerous. At the same time, risk assessment is being used.

Download or read book Gardens of the Roman Empire written by Wilhelmina F. Jashemski and published by Cambridge University Press. This book was released on 2017-12-28 with total page 656 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Gardens of the Roman Empire, the pioneering archaeologist Wilhelmina F. Jashemski sets out to examine the role of ancient Roman gardens in daily life throughout the empire. This study, therefore, includes for the first time, archaeological, literary, and artistic evidence about ancient Roman gardens across the entire Roman Empire from Britain to Arabia. Through well-illustrated essays by leading scholars in the field, various types of gardens are examined, from how Romans actually created their gardens to the experience of gardens as revealed in literature and art. Demonstrating the central role and value of gardens in Roman civilization, Jashemski and a distinguished, international team of contributors have created a landmark reference work that will serve as the foundation for future scholarship on this topic. An accompanying digital catalogue will be made available at: www.gardensoftheromanempire.org.
