    • Inglés
    Power Plants: Effects on Fish and Shellfish Behavior reviews the effects of power plant construction, operation, and maintenance on the behavior of fish and important shellfish populations such as blue crabs, crayfish, lobsters, penaeid shrimp, and bivalve molluscs. The emphasis is on the link between power plant design and fish aggregation phenomena. The effects of biocides and temperature on fish behavior are also examined. This book is comprised of 13 chapters and begins with a discussion on the economic relevance of power plants and their environmental impact on fish and shellfish populations. The potential of power generating facilities to act as a physical stimulus for fish aggregation is then considered. The effect of parameters associated with power plants, such as temperature and biocides, on fish behavior is the subject of subsequent chapters. The ecological and behavioral characteristics influencing entrainment of fish eggs and young at cooling water intakes are analyzed. This monograph is oriented to those involved in assessment of power plants on aquatic communities, including consultants, state and federal regulators, and electrical utility personnel, as well as researchers in physiology, ecology, and ethology.

    • A.G. Norman
    • Inglés
    Soybean Physiology, Agronomy, and Utilization attempts to cover and treat in logical sequence the factors that contribute to the potential and versatility of soybeans. The soybean is a major crop plant in the United States. Based on the utilization of the bean, or products therefrom, a substantial soybean industry has also developed. Its uses, agricultural and industrial, primarily depend on the high content of both protein (ca. 40%) and oil (ca. 20%) in the bean. The book begins by discussing soybean production in the United States and worldwide; the uses and economics of soybean products; and the soybean in physiological research. It explains the growth and development of soybeans. It discusses the physiological processes responsible for assimilating the plant body from the environment, namely photosynthesis, nitrogen fixation, and nitrate reduction. Subsequent chapters examine the impact of environmental variables—such as light, temperature, water, wind, and pests—on soybean plant characteristics as well as soybean breeding, production, processing, and utilization.

    • Joseph Lobue
    • Inglés
    Humoral Control of Growth and Differentiation, Volume I: Vertebrate Regulatory Factors is a part of two-volume work that introduces the reader to humoral control of growth and differentiation in vertebrates. This volume gives emphasis on chemical messengers, which have received relatively little attention in standard treatises on endocrine physiology for a number of reasons. Organized into three parts, this book begins with the physiological significance of chalones. This class of hormones is intimately associated with mitotic homeostasis as inhibitors of cell division. The book then looks into the aspects of blood cell formation and release, as well as the humoral control of organs and tissue growth. This volume also includes chapters discussing the humoral changes occurring in diseases of the blood and other pathologic states. The humoral factors influencing lymphocyte proliferation in culture are also explained. Moreover, this volume examines the effects of the more orthodox hormones upon skeletal growth and regeneration.

    • Inglés
    The Developmental Biology of Reproduction documents the proceedings of the 33rd symposium of the Society for Developmental Biology. Reproductive Biology was selected as the main theme of the symposium. The symposium aimed to draw center attention on basic aspects of reproduction in both plants and animals in the hope of stimulating research that might provide the necessary foundation for effective, practical control of human reproduction. Five areas were selected for emphasis: the formation of eggs and sperm; the activation of the egg to develop into an embryo; the genetic and biochemical events underlying the early development of the embryo; the hormonal controls operating in the reproductive process; and the general control of implantation and growth of the mammalian embryo in the uterus. Thirteen reports were given by distinguished researchers in each of these areas. All biologists interested in a broad understanding of problems of reproduction will find this symposium interesting and important for their own work.

  • Acidic Proteins of the Nucleus

    • 1 Edición
    • Ivan Cameron
    • Inglés
    Acidic Proteins of the Nucleus focuses on the functional role of acidic nuclear proteins in differential gene expression. Historically, these proteins are referred to as acidic in nature because they are insoluble in dilute mineral acids and their amino acid composition shows a preponderance of acidic over basic amino acid residues. After an introduction to DNA-binding proteins and transcriptional control in prokaryotic and eukaryotic systems, the subsequent chapters describe various approaches for isolating, separating, and characterizing acidic nuclear proteins. The core chapters specifically cover the isolation, fractionation, and characterization of acidic nuclear phosphoproteins, and the role of these proteins in cell proliferation, cell differentiation, and cell cycle. The last two chapters address the role of acidic nuclear protein in binding steroid hormones and in gene regulation. Each chapter contains some previously unpublished work and provides recommendations for future research. This book will be a good reference background for researchers of acidic nuclear proteins.

    • Inglés
    The Soil-Plant System in Relation to Inorganic Nutrition focuses on the soil-plant system in relation to the inorganic nutrition of plants. More specifically, the book investigates the dynamics of ion uptake in relation to those physical and chemical processes that must be considered both in understanding any observation made on the soil-plant system and in predicting the results of any stress placed on the system. This volume is organized into two parts encompassing seven chapters and begins with an overview of the inorganic nutrition of plants grown in the soil-plant system. This book then discusses the uptake of nutrient ions from the soil into the plant system. The emphasis is on fundamental aspects of ion movement from the soil into and through the soil solution, then into the plant root, and finally into the shoot. The next chapters consider the more practical aspects of the supply of nutrients to plants grown in the soil-plant system and how it can best be supplemented. This book examines the use of isotopes with respect to solid-phase-soil-sol... relationships; movement of ions to the roots, into the roots (active or passive), and translocation to the shoot; the mobility of nutrients; laboratory, greenhouse, and field evaluation of soil nutrient supply; and when, where, and what kind of fertilizer to apply. This book will be of interest to botanists, biologists, students, and research workers engaged in the physical and biological sciences.
