Download or read book Textiles of the Viking North Atlantic written by Alexandra Lester-Makin and published by Boydell & Brewer. This book was released on 2024-04-23 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: An examination of the uses, meanings, and social impact of Viking Age textiles. This volume offers the first full study of archaeological fabrics and their decoration found in the North Atlantic region and dating broadly from the Viking or Norse period. With contributions from both academic scholars and practitioners, it shows how approaching early medieval textiles from archaeological, historical and literary contexts, and through the processes of learning and employing the traditional skills of making them, brings about a more nuanced understanding of early medieval cloths: their creation, use and meanings within their respective societies. The book is divided into two parts. The first, "Textiles and their Interpretation", takes the reader on a journey from how wool was processed in the Viking Age, and the conservator's role in preserving and interpreting archaeological textiles, to different types of analyses that researchers use to understand and explain textiles from across the wide area of the Viking-influenced North Atlantic region. The second, "Understanding through Replicating", investigates the results of practical experiments in the reconstruction of surviving medieval fabrics and the resulting empirical conclusions that can be made about their manufacture and wider cultural implications.
Download or read book Energy Metabolism in Farm Animals written by M.W. Verstegen and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 511 pages. Available in PDF, EPUB and Kindle. Book excerpt: Animal production systems have changed dramatically over the last two decades. Knowledge of energy metabolism and environmental physio logy has increased as appears from many textbooks on these disciplines. The contents of the symposia on energy metabolism of farm animals show this and they have initially focussed on feed evaluation and later on com parative aspects of energy metabolism. They show part of the progress being made. Application of knowledge of energy metabolism for animals has a long history since Lavoisier. In addition to this, studies about the environ mental requirements of animals have shown that we are still far from ac curate assessment of these requirements in terms of nutrients and ener gy. I n model studies on energy metabolism researchers have recognized the interaction between the environment and the energy requirements of animals. Estimation of energy requirements has been done in physiolo gical, physical and behavioural studies. The impact of conditions as en countered by animals in various production systems has been approached from different viewpoints related to these different disciplines. In addi tion, various kinds of infections (bacterial, parasitic: subclinical, clini cal) have been evaluated only recently with regard to their effect on pro tein and/or energy metabolism and thus on production. People working in the field of feed evaluation have defined how che mical and physical properties of nutrition infiuence energy to be derived for maintenance and production.
Download or read book Embryonic Mortality in Farm Animals written by J.M. Sreenan and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reproductive wastage is a major inefficiency in all livestock production with embryonic mortality accounting for a major portion of this loss. Accordingly the Commission of the European Communities encouraged the organisation of a seminar on embryonic mortality in farm animals which was held in Brussels on the 11th and 12th of December 1984. This book contains the text of the papers, discussions and final summary presented at that Seminar. As a background to the Seminar, the extent and timing of embryonic loss was described for farm animals. Particular consideration was then given to the various mechanisms and signals, both embryonic and uterine in origin, that are so far known to be involved in the establishment of pregnancy. Possible causes of embryonic death including physiological, endocrinological, genetic and immunological components were outlined and discussed. The final summary contains general conclusions from the Seminar and recommendations for future research work on this topic. J.M. Sreenan M.G.

This book was released on 2012-12-06 with total page 203 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains the contributions to a workshop on stress in farm animals held on April 17-18,1986 at the Pietersberg Con ference Centre Oosterbeek. The workshop was financed by the Commis sion of the European Communities from its budget for the coordina tion of Community Agricultural Research and the Agricultural Uni versity of Wageningen (The Netherlands). Its aim was to bring together experts from different disciplines all having in common that in one way or another they were involved in stress research. Such a multidisciplinary encounter should not only provide an interesting description of present day knowledge on stress, but also promote a more integrated view on stress phenomena as they occur in higher vertebrates. In the course of this workshop the following fields of research were related to stress: endocrinology, immunology, pathology, neurobiology, ethology and theoretical bio logy. Each of these relationships was introduce& by one speaker presenting a concise state of the art. The same relationship was elaborated by a second speaker implementing the available knowledge as far as possible to the farm animal situation. Therefore in this book each discipline is represented by a duo and introduced by some integrating remarks.
Download or read book Improving Genetic Disease Resistance in Farm Animals written by Akke Jitske Akkermans and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 189 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication contains the proceedings of a seminar held in Brussels on November 8-9, 1988. The title of the seminar was "Reducing the costs of disease by improving resistance through genetics". The seminar was held as an activity of the Community Programme for the Coordination of Agricultural Research, 1984-1988. Costs of disease depend on losses caused by morbidity, mortality and production decreases and on the costs of preventive measures including vaccination and medication. Production losses often contribute a major portion to the total costs. To reduce costs of disease preventive measures like vaccination, preventive medication and hygienic procedures are applied. Genetic resistance is an attractive preventive measure because of its consistent nature in the next generations, because it precludes veterinary services and because there are no side-effects. Constraints are the long term investment, relatively slow progress per generation (in combination with production traits) and the considerable lack of knowledge about inheritance of resistance mechanisms in farm animals.

Download or read book Diagnostic Ultrasound and Animal Reproduction written by M.A.M. Taverne and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 123 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of ultrasonic imaging techniques for diagnostic purposes in veteri nary medicine and animal science has lagged far behind their use in human medicine. In the area of domestic animal reproduction, diagnostic ultrasono graphy has a relatively short history. Reports on B-mode scanning first appeared as late as 1969, when Stouffer and co-workers used it for counting foetal numbers in late gestation sheep. After Lindahl had re-evaluated the potential of two-dimensional ultrasonography for pregnancy diagnosis in sheep in 1976, results of the first large scale field-trials by Fowler and Wilkins on predicting foetal numbers during the first half of gestation in sheep were published as recently as 1980. In this year also the first paper, by Palmer and co-workers, on ultrasonic scanning of the uterus and ovaries in the mare appeared. The improvement of diagnostics which was achieved by the application of this technique is illustrated by its present routine use in clinical equine practice and sheep breeding. Besides offe ring an accurate early pregnancy diagnosis in species such as the horse, cow, sheep, goat, pig and dog, ultrasonography enables the visualization of ovarian and uterine structures for the identification of both physiological and pathological conditions. In this way it replaces or supplements the more common diagnostic techniques used by the general practitioner so far. Ultrasonography has also opened several new lines of research for clini cians and research workers.
Download or read book Summer Mastitis written by G. Thomas and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Community meeting has been organised, since over the past 15 years in different countries of Western Europe including Scandinavia, a lot of research has been directed to the summer mastitis problem. Summer mastitis in cattle is a well known disease which, because of its abruptness and the difficulties concerned in defining the predisposing factors and the pathogens involved, is hard to control. Moreover, as it is anticipated that in the transmission of the bacteria one or more dipterans are involved, the complexity in defining the disease and hence co-ordinating our scientific knowledge in relation to practical control was stimulus enough for this workshop to be organised. Our aims can be summarised in the following goals: 1. Exchange of information in the practical, technical and scientific field in order to stimulate a co-ordinated research approach at a time in which the cattle husbandry sector is under great economical stress. 2. Inform research workers from countries where the disease is or seems to be, not endemic, on aspects that might be of interest for them in the approach of comparable problems. 3. To draw up conclusions and recommendations with regard to future research activities in order to avoid needless duplication of effort.

Available in PDF, EPUB and Kindle. Book excerpt: In spite of the availability of modern broad-spectrum anthelmintic drugs, the prevention and control of helminth zoonoses remain a challenge to human and veterinary parasitologists and to physicians and veterina rians working on the field. Although the life cycles of most helminths of zoonotic importance are well known, there are still major gaps in our knowledge especially in the fields of epidemiology, diagnosis and treat ment The International Colloquium on Helminth Zoonoses held at the Institute of Tropical Medicine, Antwerp, 11-12 December 1986, laid emphasis on more recent advances made in the control and epidemiology of these zoonotic diseases. The disease complexes echinococcosis/hydatidosis, taeniasis/cysticercosis and the larva migrans-syndrome were dealth with in considerable detail. In the first chapter the phenomenon of strain variation in Echinococcus spp. is examined in the light of newer findings. The progress made in recent years towards a more specific diagnosis and drug targeting in hydatidosis is reported. In the second chapter recent advances in immunisation and treatment of cysticercosis are dealt with. The possibili ty of the existence of strain differences in Taenia saginata is also dis cussed. The third chapter is devoted to trematode zoonoses with particular reference to the situation in South-east Asia, Senegal (schistosomiasis) and Liberia (paragonimiasis). In the last chapter the larva migrans syndrome is treated in detail with special attention to its etiology and and diagnosis. Reports on lesser known nematode zoonoses like mammomono gamosis and oesophagostomiasis are included.

This book was released on 2012-12-06 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: The success of a scientific workshop depends on a delicate blend of many types of ingredients. Most important is to select a provocative topic which is at the forefront of a current investigative study. Coupled together with a relatively small but distinguished group of active research scientists known for their continued record of contributing significant findings, one has the firm foundation for an exciting and rewarding investment of time and effort. This was the setting for the first workshop organized by the European Association for Veterinary Pharmacology and Toxicology. Ruminants have been domesticated for many centuries and have served mankind as a source of dairy products, meat, wool and power. The ruminant stomach has long been - and still is - a major concern for physiologists, pathologists, clinicians and pharmacologists. This workshop was organized and convened in an attempt to strengthen the basic science of the ruminant stomach, as it applies to an economically important group of mammals. To achieve this, various topics were covered by specialists which ensured presentation of new data, followed by discussions. In this book, reviews are presented on the different topics: motility (control and regulation, neurotransmitters and endogenous substances involved); flow of digesta (comparative aspects, role of content and metabolites); food intake; rumen metabolism (chemical manipulation, metabolism of xenobiotics and drugs); pharmacology of forestomach motility and, the reticulo-rumen as a pharmacokinetic compartment.
