The importance of accurate sample preparation techniques cannot be overstated--meticulous sample preparation is essential. Often overlooked, it is the midway point where the analytes from the sample matrix are transformed so they are suitable for analysis. Even the best analytical techniques cannot rectify problems generated by sloppy sample pretreatment. Devoted entirely to teaching and reinforcing these necessary pretreatment steps, Sample Preparation Techniques in Analytical Chemistry addresses diverse aspects of this important measurement step. These include: * State-of-the-art extraction techniques for organic and inorganic analytes * Sample preparation in biological measurements * Sample pretreatment in microscopy * Surface enhancement as a sample preparation tool in Raman and IR spectroscopy * Sample concentration and clean-up methods * Quality control steps Designed to serve as a text in an undergraduate or graduate level curriculum, Sample Preparation Techniques in Analytical Chemistry also provides an invaluable reference tool for analytical chemists in the chemical, biological, pharmaceutical, environmental, and materials sciences.

Global aquaculture production has grown rapidly over the last 50 years. It is generally accepted that there is limited potential to increase traditional fisheries since most fish stocks are well or fully exploited. Consequently increased aquaculture production is required in order to maintain global per capita fish consumption at the present level. Fish farming enables greater control of product quality and safety, and presents the possibility of tailoring products according to consumer demands. This important collection reviews safety and quality issues in farmed fish and presents methods to improve product characteristics.The first part of the book focuses on chemical contaminants, chemical use in aquaculture and farmed fish safety. After an opening chapter discussing the risks and benefits of consumption of farmed fish, subsequent contributions consider environmental contaminants, pesticides, drug use and antibiotic resistance in aquaculture. Part two addresses important quality issues, such as selective breeding to improve flesh quality, the effects of dietary factors including alternative lipids and proteins sources on eating quality, microbial safety of farmed products, parasites, flesh colouration and off-flavours. Welfare issues and the ethical quality of farmed products are also covered. The final part discusses ways of managing of product quality, with chapters on HACCP, monitoring and surveillance, authenticity and product labelling.With its distinguished editor and international team of contributors, Improving farmed fish quality and safety is a standard reference for aquaculture industry professionals and academics in the field. - Reviews safety and quality issues in farmed fish and presents methods to improve product characteristics - Discusses contaminants, persistent organic pollutants and veterinary drug residues and methods for their reduction and control - Addresses important quality issues, genetic control of flesh characteristics and the effects of feed on product nutritional and sensory quality

This publication presents as a reference document the first issuance of the national guidelines for health planning as they were published by the department of health, education, and welfare on march 28, 1978. This is accompanied by a reprinting from the federal register of the preambles to the final rule and to the two notices of proposed rulemaking which preceded the final rule. A purpose of these guidelines is to assist health systems agencies in developing health systems plans and to help clarify and coordinate national health policy. This first issue consists of resource standards with respect to nine specific categories of health services and facilities. General hospital beds, obstetrical inpatient services, neonatal special care units, pediatric inpatient services, open heart surgery, cardia catheterization, radiation therapy, computed tomographic scanners, and end-stage renal disease.

No issue is more hotly debated than how, or even if, a politician's private life affects his public competence. In "A Question of Character John F. Kennedy's two lives--public and private--are examined to answer this timely question. Respected historian and biographer Thomas C. Reeves reveals discrepancies between JFK's public persona, which has reached mythic proportions, and his scandalous private behavior. Most illuminating is the constant theme or Joe Kennedy's almost total control of JFK's behavior and politics throughout most of his son's career. "The John Kennedy who emerges from these pages was not a man of good moral character. He was reared not to be good but to win." -- "Los Angeles Times Reeves has provided the most truthful and balanced assessment of John F. Kennedy to date. Written more in sorrow than in anger, "A Question of Character explores the sensitive and difficult question of how people, and history itself, ought to judge the relationship between personal character and national leadership.
