  • The Analysis of Response in Crop and Livestock Production

    • 3 Edición
    • John L. Dillon + 1 más
    • Inglés
    The role of the agricultural scientist is to manipulate crop and livestock response phenomena so that they serve society's needs better, enabling countries to obtain full benefit from their agricultural resources. By producing food more efficiently, resources can be made available for non-agricultural development and other needs beyond the essentials of food and fibre. This text provides an introductory outline of the analytical principles involved in appraising the efficiency of crop-fertilizer and livestock-feed response. It provides students of both agricultural science and economics with a simple but formal exposition of the why, how and wherefore of the principles of crop and livestock analysis, thereby helping to further co-operative effort among biological and economic researchers. The third edition has been updated and revised, with additions relating to the principles of modelling, the concept of economic duality as pertinent to response processes, the appraisal of aggregate response, and the economics of response research.

  • Learning and Memory

    A Biological View
    • 1 Edición
    • Joe L. Jr. Martinez
    • Inglés
    Learning and Memory: A Biological View is a comprehensive textbook about the neurobiology of learning and memory. Topics covered include developmental approaches to the memory process; anatomical correlates of neuronal plasticity; drugs that modulate learning and memory; and biochemical correlates of learning and memory. The link between aging and memory is also discussed, along with electrophysiological approaches to the study of memory. Comprised of 12 chapters, this book begins with a review of historical traditions that influenced research on the biological basis of learning and memory. Experimental findings suggesting that the engram for a simple classically conditioned skeletal response may be in the cerebellum are also presented. The next chapter emphasizes the importance of anatomical mechanisms that could mediate learning, plasticity, and memory storage in young and adult animals. Subsequent chapters explore the influence of peripheral hormones and particularly opioid peptides on complex behavior such as learning and memory; the contribution of individual neurotransmitter systems to learning; the psychopathology of aging; and long-term potentiation as a model of the way the central nervous system stores information. Learning in complex vertebrate systems and direct stimulation of various brain nuclei are also examined. The final chapter presents a neurobehavioral analysis of the structure of memory formation that utilizes lesions and explores human memory pathology. This monograph is intended for advanced undergraduate students, graduate students, and research workers in the field of memory.

  • T and B Lymphocytes: Recognition and Function

    • 1 Edición
    • Fritz Bach
    • Inglés
    T and B Lymphocytes: Recognition and Function is the 16th volume of the 1979 ICN-UCLA Symposia on Molecular and Cellular Biology. This book is organized into seven sections, encompassing 74 chapters that summarize molecular level progress in the field of immunobiology. It emphasizes cell membrane, techniques developed for its analysis, and varied products of the major histocompatibility complex, as well as other receptors on cells of the immune system. The book starts by describing two approaches for molecular association evaluation. First is the use of artificial membranes or lipid vesicles for the incorporation of antigens for recognition by T-lymphocytes both at the afferent and efferent levels. Second is the chemical crosslinking of cell surface components with a variety of different crosslinking reagents. This is followed by a discussion on the molecular nature of a T-cell receptor that provides insights of the target(s) recognized by T-lymphocytes. Several chapters discuss data dealing with the issue of the apparent differential recognition by T- and B-cells while both use the same VH genes. Antiidiotypic sera, together with the activity of ""regulator"" T-cells, are also discussed, with regard to their role in networks of regulation of the immune response. This book presents works demonstrating that human T-lymphocytes can also be cloned and both noncytotoxic proliferating T-lymphocytes and Tc can be so obtained. This is along with the continuing studies regarding heterogenity of B-lymphocytes as well as macrophages. Part V focuses on the interaction between lymphocyte and virus and molecular modifications of viral-infected cells. The subsequent section deals with recognition, reactivities, and function of T- and B-lymphocytes. Considerable chapters in this section discuss T-cell cytotoxicity, dichotomy of MHC control over anti H-Y cytotoxic T-cell responses, mouse alloantibodies, and mixed lymphocyte reactions. The concluding part describes immunological tools, such as synthetic membranes and cloned T-cells with biological function.

    • Inglés
    Viral Transformation and Endogenous Viruses is a collection of papers presented at the symposium on ""Viral Transformation and Endogenous Viruses"" held at Vanderbilt University on April 1-2, 1974. Contributors discuss the viral function(s) responsible for the transformation of the cells that are infected with oncogenic viruses, emphasizing the type of changes that characterize transformed cells and the regulatory mechanisms that are altered after malignant transformations. This volume is organized into 10 chapters and begins with an overview of DNA-containing tumor viruses, particularly Simian Virus 40 (SV40) and its mutants with DNA deletions, insertions, and duplications. The integration and transcription of adenovirus DNA is considered, along with the characteristics of temperature-sensitiv... mutants of these viruses. The reader is then introduced to the chemistry and biology of RNA-containing tumor viruses, which are useful reagents to study neoplastic transformation both in vivo and in vitro. A major aspect of these viruses concerns the analysis of their genome at the chemical and genetic levels. The last part of the book is devoted to biochemical and genetic analyses of endogenous viruses isolated from avian cells. This book is a valuable resource for scientists and investigators in fields such as pathology, molecular virology, molecular biology, microbiology, oncology, and biochemistry.

  • An Introduction to Animal Law

    • 1 Edición
    • Cooper
    • Inglés
    Legislation relating to animals has ancient origins and in many civilizations certain species have held particular significance, be it religious, cultural, nutritional, or sporting. As a general rule, the law was primarily concerned with animals as property, rather than in need of protection, until the 19th century. Since the 1970s animal law has proved to be a growth area in the production and enforcement of both national and international legislation. This has been particularly so in the areas of conservation and welfare and there has been extensive legal and philosophical consideration of the status of animals.This book is not intended to be a standard text, but rather a handbook in the true sense, a guide for the lay person--namely, to help the non-lawyer to understand the basic concepts of animal law and to provide the lawyer (who is the lay person in the world of animal science) with an introduction to relevant concepts and literature which are not normally found in the conventional legal texts.
