This publication provides a structured approach to analyzing hazards to groundwater quality, assessing the risk they may cause for a specific supply, setting priorities in addressing these, and developing management strategies for their control. This book summarizes which pathogens and chemicals are relevant to human health, how they are transported, reduced, removed or retarded; provides practical guidance on characterizing the drinking-water catchment area and assessing potential health hazards; provides guidance on prioritising both hazards and management responses; presents key information on potential management actions and explains their integration into a comprehensive Water Safety Plan from catchment to consumer; and describes policy, land-use planning and implementation of pollution prevention, groundwater, with overviews of specific management approaches applicable to agriculture, sanitation, industry, mining, military sites, waste disposal and traffic.--Publisher's description.
"An eloquent and essential correction to contemporary discussions of the American working class."—The Nation From the ongoing issues of poverty, health, housing, and employment to the recent upsurge of lethal police-community relations, the black working class stands at the center of perceptions of social and racial conflict today. Journalists and public policy analysts often discuss the black poor as “consumers” rather than “producers,” as “takers” rather than “givers,” and as “liabilities” instead of “assets.” In his engrossing history, Workers on Arrival, Joe William Trotter, Jr., refutes these perceptions by charting the black working class’s vast contributions to the making of America. Covering the last four hundred years since Africans were first brought to Virginia in 1619, Trotter traces the complicated journey of black workers from the transatlantic slave trade to the demise of the industrial order in the twenty-first century. At the center of this compelling, fast-paced narrative are the actual experiences of these African American men and women. A dynamic and vital history of remarkable contributions despite repeated setbacks, Workers on Arrival expands our understanding of America’s economic and industrial growth, its cities, ideas, and institutions, and the real challenges confronting black urban communities today.
Evidence-based medicine is a concept that has come to the fore in the past few years. Clinicians are increasingly encouraged to practise patient management based on available evidence in the scientific literature. For example, new pharmacological therapies are only used when large randomized trials have 'proven' that a particular drug is better than existing ones. This is also the case in surgical specialties, although surgery has traditionally seen a lack of useof this information, with individual surgeon's preferences being most influential in treatment choices. However, more recently, there has been a large expansion of trials and studies aimed at providingsurgeons with information to guide their choices using firm evidence. This new edition has been revised and expanded to include new data where relevant, and also features a new chapter on pituitary surgery. Landmark Papers in Neurosurgery 2e remains a key collection of the most important trials and studies in neurosurgery, allowing the reader to rapidly extract key results, and making it essential reading for all neurosurgeons and trainees in the field.
The chapters of Studies on Periodontal Disease comprise four parts. Part 1 provides basic sciences from the general to the particular. The findings of cell culture and animal models supply the mechanism between periodontal disease and oxidative stress. In part 2, human clinical studies are mainly addressed. The effects of periodontal therapy on circulating oxidative stress are also discussed. The relationships between periodontal disease and systemic diseases are examined in part 3. The involvement of oxidative stress and inflammation are discussed through in vivo and in vitro study results. Part 4 discusses future strategies, including the effects of antioxidants and nutrition on periodontal disease. This thorough examination of the relationship between oxidative stress and periodontal disease is essential reading for researchers in oxidative stress and periodontal clinicians, alike.
