A comprehensive survey of the use of ultrasound in management of infertile patients is presented in this publication. Particular atten-tion is given to recently developed techniques such as assessment of endometrial changes, ovarian blood flow measurements, and per-cutaneous oocyte retrieval for in vitro fertilization. The very re-cent technique of transvaginal sonography is presented and richly illus-trated with original results obtained in biopsy-guided oocyte re-trieval, and in the precise delineation of follicle size and number for infertility treatment. Guidance in the interpretation of ultrasonic findings, which include potential limitations and pitfalls, is provided in each chapter. Researchers and practitioners interested in the management of infertile patients will find this volume indispensable.

Thousands of people continue to die from heat. Heat illnesses and advice for preventing heat casualties at work, during heatwaves, sport and the effects of global warming are described. A new perspective on thermoregulation integrates physiological and psychophysical regulated variables. Heat stress indices, the WBGT and the SWreq are presented. It is time to understand and routinely use computer simulations of people in hot conditions. How to understand how a model can be constructed is also described. This book provides an accessible, concise and comprehensive coverage into how people respond to heat and how to predict and avoid heat causalities. A practical productivity model, and Burn thresholds, complete the book which begins with up to date knowledge on measurement of heat stress, heat strain, metabolic rate and the thermal properties and influences of clothing.Features Provides methods and regulations through international standards Illustrates the WBGT and analytical heat stress indices and how to construct a thermal model Discusses the role of clothing on heat stress and thermal strain Presents a new model for predicting productivity in the heat Offers a new method of human thermoregulation Considers heat illness and prevention during heatwaves and in global warming

This practical, two volume handbook provides a critical look at state-of -the-art ultrasound techniques and equipment. It is a comprehensive reference with numerous black/white and color ultrasonograms, tables and graphs. The volumes include extensive literature citations which assist the investigator in finding more in-depth references.This work focuses on the recent remarkable expansion in both diagnostic techniques and clinical applications. It reports findings based on an unusually large patient population over al long time period. It presents the accuracy and limitations of various aspects of ultrasound.

Athletes and nonathletes frequently consume too little water or fluids, affecting exercise performance as well as overall health. This book comprehensively reviews the aspects relating to body fluid balance, rehydration, and physical exercise. It provides background on body water balance and turnover, topics related to electrolyte balance, and sweating as the basis for thermoregulatory and fluid homeostasis during exercise. In addition, chapters cover body water balance evaluation and regulation; cardiovascular and metabolic responses to fluid imbalance; effects of dehydration on aerobic power, muscle strength, and cognitive function; fluid intake timing; and optimal beverage selection.

The book is comprised of more than a dozen chapters on fungi from different substrates including fossilized leaves. It discusses association of fungi occurring on important plants, some animals, and saprophytic substrates. Besides the taxonomic information, some ecological aspects like distribution and substrate/host preferences are discussed.

This updated and expanded Second Edition of Dr. Erickson's Analytical Chemistry of PCBs appears a decade after the first and is completely revised and updated. The changes from the First Edition reflect the significant growth in the area and a growing appreciation of the importance of PCB analysis to our culture. This book is a comprehensive review of the analytical chemistry of PCBs. It is part history, part annotated bibliography, part comparison, and part guidance. Featuring a new chapter on analyst/customer interactions and several new appendices, the Second Edition is an invaluable resource for both chemists with no experience in PCB analysis and seasoned PCB researchers. All topics have been more thoroughly treated and updated in this new edition to reflect advances made in the last decade, especially:

Over the past four centuries botanists and gardeners in the British Isles have gathered, maintained and propagated many varying species of plants. Their work has been documented in innumerable books and articles which are often difficult to trace. The Dictionary of British and Irish Botanists and Horticulturalists represents a time-saving reference source for those who wish to discover more about the lives and achievements of the horticulturalists listed. The dictionary's utility comes not only from indicating the major publications of the named authors, but also the location of their herbaria and manuscripts.; The previous 1977 edition of the Dictionary has for many years been a much used source of information for botanists, botanic artists and archivists. In this revised edition the scope has been expanded to include among its 13,000 entries flower painters in addition to botanical artists over 1400 entries and, for the first time, garden designers.; Finally the Dictionary should have international appeal since so many botanists and gardeners worked on collective plants overseas, in particular in North America and the British Commonwealth.; Each entry gives, wherever possible, details of dates and places of birth and death, educational qualifications, professional posts, honours and awards, publications, location of plant collections, manuscripts, drawings and portraits. Its main function, however, is to provide further biographical references to books and periodicals. Comprehensive classified indices facilitate access by professions and activities, countries, and plant interests.

An exhaustive treatment of all British and Irish botanists through 1976.
