A guide to the methodologies, typical mathematical notation, and assumptions used in risk assessment calculations Risk Assessment describes the methodologies, the math, and assumptions needed in risk assessment calculations and explores the various statistical analysis procedures that are used for estimating the parameters employed in risk assessment approaches. The author—a noted expert in the field—outlines a logical step-by-step approach to assessment: Identify a hazard; Analyze the risk associated with that hazard; and Determine if the elimination, or control of the risk is warranted. The text puts the focus on assessing environmental risk and describes the basics used in hypothesis testing to determine when there are differences in environmental quality at various locations. The author describes statistical techniques in approachable terms that are designed to be understandable to the non-statistician. The text downplays mathematical notation while offering clear explanations for the development of equations. It highlights applications with numerous examples of problems of censored data as they influence the use of alternative tests. In addition, the text focuses on both parametric and non-parametric procedures. This important resource: Describes in understandable terms the methodologies, typical mathematical notation, and assumptions used in risk assessment calculations Explores the fundamental calculation procedures and approaches for risk characterization Contains a wealth of example problems of interpretations of environmental monitoring results and shows how each procedure is used Includes problems at the end of each chapter that stress the fundamental concepts outlined Written for senior undergraduate and graduate students and as a course text in engineering, Risk Assessment offers a guide to the fundamental calculation procedures and methodologies for characterizing risk in clear and accessible terms.
Constructed wetlands are proving to be the best natural treatment system for landfill leachates. Most of the contaminants in landfill leachates are degraded in treatment wetlands. Potential for long-term sustainability and significant cost savings are attractive features of this eco-technology. Documentation of the experience in this use of constructed wetlands has been limited. Constructed Wetlands for the Treatment of Landfill Leachates is the first compilation of the results of research from North America and Europe. Originally presented at an international symposium, this collection of papers offers the most recent research findings from the leading researchers in this new and innovative natural treatment system. Specific issues addressed in the text include: leachate characteristics, and the potential for treatability by constructed wetlands wetland treatment, processes and transformation use of constructed wetlands in cold climatic conditions assessment of the tolerance of wetland plants to the toxicity of leachates role of plants in the treatments of leachates integrated wetland systems performance of different wetland treatment systems cost comparisons of wetland technology vs. traditional treatment technologies The potential for environmental contamination due to leachates from landfills is increasing, and there is an urgent need to find ways and means to treat leachates in a sustainable way Constructed Wetlands for the Treatment of Landfill Leachates will provide an invaluable source of information on the subject for scientists, engineers, practitioners, policy makers, and regulatory officials.
This book reveals the most significant medical fraud in history. The theory that you can prevent illness by injecting poisons into the bodies of healthy people is dangerous quackery and sin. All true science has proven the practice of vaccination to be ineffective and unsafe. But the medical establishment has been lured into the superstitious practice, hook, line, and sinker. It is not merely a matter of ignorance that the debilitating practice flourishes. It is, at its core, being promoted by those who know it is unsafe and ineffective. There is a malevolent spirit behind the practice. It is part of a conspiracy against God and man. While most doctors are unwitting, some are willing minions of that old serpent, called the Devil, and Satan, who are quite happy to kill people for profit. Jesus describes such men: "Ye are of your father the devil, and the lusts of your father ye will do. He was a murderer from the beginning, and abode not in the truth, because there is no truth in him. When he speaketh a lie, he speaketh of his own: for he is a liar, and the father of it." John 8:44.
Supported by a companion skills volume and website, Foundation Studies for Caring is a comprehensive introductory text for all health professionals, which maps directly on to the key skills framework. Taking a student-centred learning and interprofessional approach, it is the most inclusive and engaging theory text in the market.
