The Value of Fibre


Book Description

Dietary fibre has been associated with impaired nutrient utilisation and reduced animal performance. A minimum amount of dietary fibre is required to maintain normal physiological functions in the gastrointestinal tract. This book reviews the latest advances in the understanding of dietary fibre for animal nutrition. Fibre clearly has more value than was once thought. This book attempts to define not only the analytical constraints but also the advances in understanding its role in intestinal development and health in both swine and poultry. It identifies how we can exploit fibre to the advantage of the host. Stimulating the gastrointestinal microbiota (often referred to as the second brain) to digest more fibre creates a more favourable environment for intestinal health. This outcome is especially important in antibiotic free diets. The type of fibre employed, the use of exogenous enzymes and the interaction between them, the gastrointestinal microbiota and the host will be covered in detail throughout the chapters. This book discusses the practical application of this research and has been written for all animal scientists, nutritionists, feed producers and anyone interested in exploring new developments in the understanding of dietary fibre.




Dietary Fibre — A Component of Food


Book Description

Dietary fibre is now recognized as a vital component of good daily nutrition, yet its properties and specific role in the digestive system are still being investigated. The involvement of government agencies, the food industry and health professionals - as well as public interest - make this global overview, Dietary Fibre - A Component of Food, an important contribution to the literature on the subject. The cooperation of experts from different research centers and their peer review of each other's papers enhance the value of the book, since it presents consolidated views and objective assessments on such key issues as fibre analysis and mineral bioavailability. The seventeen chapters are grouped into three sections. The background papers deal with biochemical and analytical characteristics: e.g. the physico-chemical properties of food polysaccharides and bacterial fermentation in the colon. The papers on physiological effects deal with the physiological function of dietary fibre throughout the gastrointestinal tract: its influence on protein, lipid and carbohydrate digestion and absorption and its role in bile acid metabolism and faecal bulking. The third section of papers focuses on the prevention and treatment of disease: gastrointestinal disorders, obesity, diabetes mellitus, and hyperlipidemias.

Dietary Fiber


Book Description

Dietary fibre is a broad term that includes non-digestible complex carbohydrates, such as cellulose, hemicellulose, mucilage and colloids, like pectin, carrageenan and arabic, xanthan or guar gum. Dietary fibre is a plant basic structural factor and exists in water-soluble and non-soluble form. Soluble fibre is found in certain fruits and vegetables such as oranges, apples, bananas, broccoli and carrots. It also exists in large amounts in legumes such as peas, soybeans, lentils and beans. Secondary sources include oat bran, soybeans, nuts and seeds. Sources of insoluble fibre are whole grain foods, wheat bran, nuts and seeds. Vegetables, such as green beans, leek, cabbage, cauliflower, broccoli, radish and carrot are high-fibre foods. Purported benefits of fibre include gastro-intestinal health, cardiovascular health, weight management, satiety, glycemic control and prebiotics. Recommended intakes, 2035 g/day for healthy adults and children over age 5, are not being met, because intake of good sources of dietary fibre, fruits, vegetables, whole and high-fibre grain products, and legumes are low. The importance of food fibres has led to the development of a large and potential market for fibre-rich products and ingredients and nowadays there is a trend to find new sources of dietary fibre. In recent years, dietary fibre has received increasing attention from researchers and industry due to the likely beneficial effects on the reduction of cardiovascular and diverticulitis diseases, blood cholesterol, diabetes, and colon cancer. The contributors to this volume provide an assessment of not only the impact of the biological and functional potential of different dietary fibre sources but also their health implications.

Forensic Examination of Fibres


Book Description

In order for forensic fibre examiners to fully utilize fibre and textile evidence during their analysis, they require not only specialised forensic knowledge but also in-depth knowledge of fibres, yarns and fabrics themselves. Production, both the chemical and physical structure, and the properties of these materials is required in order to determine the value of fibre evidence. This includes knowing production figures, fashion changes, sudden arrivals of new materials, dye variability, and numerous other factors that may have a bearing on the information obtained. Fully updated with the latest advances, Forensic Examination of Fibres, Third Edition continues in the tradition of the First (1992) and Second Editions (1999) as the premier text on the subject of forensic fibre analysis. The international team of contributing authors detail the recovery of the evidence—through the different stages of laboratory examination—to the evaluation of the meaning of findings. The coverage has been considerably expanded, and all material, has been revised and wholly updated. Topics covered include examining damaged textiles, infrared microspectroscopy and thin layer chomatography, and colour analyses. This edition also highlights the critical role of quality assurance in ensuring the reliability of the technical observations and results, and, in doing so, looks at the implications of supervisory managers and labs in the accurate and responsible analysis of such evidence. Features include: Outlining evidentiary process from collecting and preserving the evidence at the crime scene through the laboratory analysis of fibres Detailing the latest developments and emerging technologies including Kevlar and other such advances in fibre technology Coverage of a broad array of fibres both, natural (cellulose, protein, and mineral) and man-made fibres including synthetic, inorganic and regenerated Forensic Examination of Fibres, Third Edition is a much-needed update to the classic book, serving as an indispensable reference to crime scene technicians, laboratory forensic scientists and microscopists, students in police, forensic, and justice science programs.

Fiber


Book Description

The world of fiber optic connections reaching neighborhoods, homes, and businesses will represent as great a change from what came before as the advent of electricity. The virtually unlimited amounts of data we’ll be able to send and receive through fiber optic connections will enable a degree of virtual presence that will radically transform health care, education, urban administration and services, agriculture, retail sales, and offices. Yet all of those transformations will pale compared with the innovations and new industries that we can’t even imagine today. In a fascinating account combining policy expertise and compelling on-the-ground reporting, Susan Crawford reveals how the giant corporations that control cable and internet access in the United States use their tremendous lobbying power to tilt the playing field against competition, holding back the infrastructure improvements necessary for the country to move forward. And she shows how a few cities and towns are fighting monopoly power to bring the next technological revolution to their communities.
