    • 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.

    • Arnold Reif
    • Inglés
    Immunity to Cancer documents the proceedings of a conference on ""Immunity to Cancer"" held at Williamsburg, Virginia, September 10-12, 1984. This was the first open conference since the New York Academy of Sciences meeting in 1975 that attempted to address the entire range of topics encompassed by tumor immunology and immunotherapy. The papers presented in this volume were invited from experts in diverse areas of tumor immunology and closely related subjects. There was an attempt to proceed logically from a consideration of the antigenicity of tumors and the use of monoclonal antibodies to examine specific antigens, to a review of regulatory and effector mechanisms. Immunological approaches to therapy were then considered systematically, both for classical modes of immunotherapy and for the newly expanded categories of biological response modifiers or biomodulators. Also included were papers on vaccination against cancer and on the analogy between the strategies for chemotherapy and immunotherapy.

    Origins of Molecular Biology: A Tribute to Jacques Monod consists of contributions of scientists narrating their experiences with Jacques Monod. Significantly, the history of various discoveries Jacques Monod made is unfolded. This book pictures Jacques Monod through the eyes of his technician, secretary, peers, friends, and even opponents. It notes that the depiction of the same discovery may be told differently by different scientists who worked at the same time in the same laboratory. The personality of the contributor sometimes influences the narration. Through this book, one can learn how a great scientist receives, discusses, rejects, accepts, assimilates, and creates ideas; how ideas are turned into experiments; how experimental results are interpreted and how concepts are born. In a word, it tells how science is constructed.

    Until the 1980s, global increases in food production exceeded the concomitant growth of human populations. However, progressively agriculture is becoming unable to meet the world-wide per capita needs for food. Unless there is major international cooperation in addressing the problems associated with population control, it is predicted that the global human population will reach more than 14 billion by the year 2050, with provision of adequate food, fuel and space for such an increased population unachievable.These problems are accentuated by factors such as world-wide reductions in soil fertility, the accelerating degradation of land that is suitable for food production through soil erosion, the world-wide trend for migration of human populations from rural habitats to cities and extremely rapid rates of global deforestation.Possib... solutions to global sustainability in agriculture and natural resources must involve an integration of ecological, sociological, cultural, and economic considerations, as well as mandated international and national policies. This publication outlines these problems and attempts to seek solutions.

    Molecular and Cellular Approaches to the Control of Proliferation and Differentiation focuses on molecular and cellular approaches used to control cell proliferation and differentiation. This book discusses the basic mechanisms involved in the regulation of cell growth, emphasizing the coupling of proliferation and the progressive expression of several specific cellular phenotypes. This text is organized into three sections encompassing 12 chapters and begins with an introduction to cell proliferation and how it is regulated by growth factors and nuclear protooncogenes in cell proliferation. The book then discusses mitosis and its investigation by means of the cell biological, genetic, biochemical, and immunological approaches, along with the model for mitotic regulation. The next chapters examine the manner in which cell structure is involved in the selective expression of genes associated with proliferation and differentiation and, how gene expression in response modulates both intracellular (nuclear matrix and cytoskeleton) and extracellular (extracellular matrix) architecture. The extent to which common signaling mechanisms and regulatory events are operative in the control of proliferation and differentiation is also addressed. The book concludes by analyzing the involvement of histone modifications in the condensation of mitotic chromosomes. This book is of interest to advanced undergraduate students, as well as to graduate students and researchers in genetics, cell biology, biological chemistry, microbiology, and immunology.
