This is a unique compilation on the use of leaching/extraction methods in different fields. The use of leaching test methods is increasing in various areas including: waste treatment and disposal; incineration of waste; soil clean-up and reuse of cleaned soil; sludge treatment. This has led to (and may increasingly lead to) the development of a large number of very similar tests in these different fields. However, these developments are taking place with no clear understanding of their mutual relationships. In view of these developments, efforts are needed to harmonize the leaching procedures that could be adapted for different matrices, as well as validate the use of existing tests in other fields. The development of a wide variety of leaching/extraction tests for different matrices is undesirable from a regulatory point of view and undesirable for industry. Clarity in testing is crucial in producer-consumer relations. This collective document will assist in improving the understanding of leaching from a variety of sources and will, where appropriate, help to bring together the approaches used in different technical fields and in different countries.
The publication of the Department of Health White Paper "The Health of the Nation" (1992) and "Our Healthier Nation" (1998) gave emphasis to the importance of nutritional health of the nation at all ages. It is clear that the achievement of specific targets for pregnancy and infancy as set out in the White Paper will involve the training of all health care professionals in nutrition education. This book responds to the challenge and focuses on good nutrition for and during pregnancy, in low birth-weight infants, and during infancy. It has a strong public health emphasis, dealing with health prevention issues for the Nation's younger population. The text is written as a scientific reference book for those seeking to apply science in the support of a successful pregnancy and in the prevention of nutritional problems during foetal and early post-natal life. The importance of optimal nutrition during these periods of life is emphasised by the overwhelming evidence that nutritional problems in early embryonic life may cause congenital malformations and during late foetal life and early post natal life may set the molecular programme for later disease development.
This volume presents the proceedings of the International Conference on The Science and Engineering of Recycling for Environmental Protection (WASCON 2000), of which a number of themes have been identified. All are inter-related and inter-dependent in so far as potential users of secondary, recovered or recycled material have to be assured that the material is environmentally safe and stable. It is the environmental challenge that forms a leading theme for the conference, and the themes of quality assurance and quality control support this aspect. In terms of use of 'recovered' materials, science and engineering play important and inter-dependent roles and this is reflected in themes which f...
"This publication deals with the broodmare, which is the key animal in the Equine chain. In the new competitive context of Equine Industry, the mare should foal a healthy offspring yearly at an optimum cost. The foal should be born and weaned at the accurate months of the year to fit the particular goals of production, i.e. races, sports or leisure horses. The improvement of knowledge of the biology of pregnancy and lactation on the one hand and of the nutrition and the interaction between nutrition and physiology of reproduction on the other hand is of major concern to the equine industry. The book is divided in six parts: - Pregnancy - Lactation - The foal - Feeding practices and pasture m...
The taking in and use of food and other nourishing material by the body. Nutrition is a 3-part process. First, food or drink is consumed. Second, the body breaks down the food or drink into nutrients. Third, the nutrients travel through the bloodstream to different parts of the body where they are used as "fuel" and for many other purposes. To give the body proper nutrition, a person has to eat and drink enough of the foods that contain key nutrients. This book examines new and important research in this field.
The International Symposium on Ruminant Physiology (ISRP) is the premier forum for presentation and discussion of advances in knowledge of the physiology of ruminant animals. This book brings together edited versions of the keynote review papers presented at the symposium.
This book is designed to provide a comprehensive insight into current perspectives and challenges in adipose tissue biology. In Adipose Tissue Biology, scientists and clinicians discuss adipocyte precursors, differentiation and growth, brown and white adipose tissue, gender, inflammation, dietary and genetic determinants of fat mass, together with evolutionary and developmental aspects of adiposity.
Hormones and Reproduction of Vertebrates, Volume 2: Amphibians is the second of five second-edition volumes representing a comprehensive and integrated overview of hormones and reproduction in fishes, amphibians, reptiles, birds, and mammals. The book includes coverage of endocrinology, neuroendocrinology, physiology, behavior, and anatomy of amphibian reproduction. It provides a broad treatment of the roles of pituitary, thyroid, adrenal, and gonadal hormones in all aspects of reproduction, as well as descriptions of major life history events. New to this edition is a concluding assessment of the effect of environmental influences on amphibians. Initial chapters in this book broadly examine...
International Review of Cytology presents current advances and comprehensive reviews in cell biology, both plant and animal. Articles address structure and control of gene expression, nucleocytoplasmic interactions, control of cell development and differentiation, and cell transformation and growth. Authored by some of the foremost scientists in the field, each volume provides up-to-date information and directions for future research.This volume brings together current information on the localization and roles of RNAs in cell-lineage determination and subsequent patterning in embryonic development. Guest co-editor Lawrence Etkin is one of the leading researchers in molecular genetics of Xeno...
