  • Groundwater Resource Development

    • 1st Edition
    • L Hamill + 1 more
    • English
    Groundwater Resource Development describes the basic steps involved in the development of a groundwater resource in the search for productive aquifers. This book discusses groundwater exploration, construction and testing of water wells, water quality and pollution considerations, and groundwater management. This text is comprised of 10 chapters and begins by presenting the steps in the evaluation, development, and management of an aquifer for water supply. The reader is then introduced to the fundamentals of groundwater, with emphasis on their origin and occurrence as well as the influence of porosity and permeability on groundwater accumulation, migration, and distribution. The chapters that follow focus on groundwater exploration, assessment of aquifer recharge and potential well yield, and factors affecting the quality of groundwater. The issues to be considered in well design and construction are also highlighted, along with aquifer hydraulics and pumping tests, groundwater pollution, and optimum management of groundwater resources. This text concludes with a chapter on techniques used in modeling the response of a groundwater reservoir. This book will be of value to geologists, civil engineers, environmental scientists, mathematicians, chemists, water well contractors, and others involved in the profession of water engineering.
  • The Origins of Agriculture

    An Evolutionary Perspective
    • 1st Edition
    • David Rindos
    • English
    The Origins of Agriculture: An Evolutionary Perspective presents an alternative approach to understanding cultural variation and change. It aims to demonstrate that domestication and the origin of agricultural systems are best understood by attempting to explicate the evolutionary forces that affected that development of domesticates and agricultural systems. The book begins by discussing cultural change, the domestication of plants, and the origin of agricultural systems in the most general of terms. It considers Darwinism in some depth, concentrating on the relationship between natural selection and cultural change. Subsequent chapters examine the world of domestication and agriculture and present a series of concepts that may permit a more natural explanation for these processes. These include concepts such as incidental domestication, specialized domestication, and agricultural domestication. The final two chapters present models for the origin and spread of agricultural systems based upon Darwinian evolutionary theory.

  • Animal Memory

    • 1st Edition
    • Werner K. Honig + 1 more
    • English
    Animal Memory is based on the proceedings of a symposium held at Dalhousie University in the summer of 1969. Each of the seven chapters provide broad coverage of the topic with which it is concerned, and the experimental work reported is representative of the most significant developments in the field. The book includes two studies on associative memory—the memory of one event which is essential to its association (over a delay) with subsequent events. One study shows that shows that animals can remember events from one learning trial to the next and that their behavior will be determined largely by the sequences of trials with differing outcomes; the other presents research on the association of flavors with toxicosis in a conditioning paradigm. Separate chapters deal with retentive memory—the retention and forgetting of learned behavior over time; and the physiological basis of memory in terms of consolidation theory. These studies demonstrate that animals do forget and examine theories of forgetting. The final chapter provides a critical discussion based on all of the foregoing material in which the topics covered in the book are related to current work on human retention and forgetting.
  • Insecticides

    Analytical Methods for Pesticides, Plant Growth Regulators, and Food Additives, Vol. 2
    • 1st Edition
    • Gunter Zweig
    • English
    Analytical Methods for Pesticides, Plant Growth Regulators, and Food Additives, Volume II: Insecticides contains detailed analytical procedures for analysis of 47 widely used insecticides. This volume is composed of 47 chapters that cover the history, biological and chemical properties, and physical constants of these insecticides. Each chapter presents first the general information, followed by intensive discussion of the methods of occurrence and residue analysis of the insecticide. Methods of analysis covered in each chapter include chemical methods, gas-liquid chromatography, colorimetry, and enzymatic techniques. Each chapter also provides analysis of phosphorus and acetylcholinesterase inhibition of the insecticide, which is classified into two groups, namely, organochlorine and organophosphorus. Agriculturists, analytical chemists, and toxicologists will find this book rewarding.
  • Micro Aerosol

    Physiology, Pharmacology, Therapeutics
    • 1st Edition
    • Lucien Dautrebande
    • English
    Microaerosols: Physiology, Pharmacology, Therapeutics presents a summary of the experimental and technical data on aerosols. This book focuses on the production, measurement, sampling, and biological importance of submicroscopic and submicronic air-borne particles and to their pharmacological, therapeutic, and physiological effects after their deposition in the respiratory tract. Organized into 22 chapters, this book begins with an overview of the process of obligatory liquid filtration. This text then examines the factors that affect the sizing and numbering of aerosols, including the duration of the aerosol dispersion into a closed space, the duration of aerosol sampling, and the location of the particles. Other chapters consider the authenticity of the penetration of aerosols into the pulmonary depths. This book discusses as well the recommendations for preparations of airway dilating solutions. The final chapter deals with the effects on the lungs of airway constricting substances dispersed in aerosols. This book is a valuable resource for physicians.
  • Pigment Cell Growth

    Proceedings of the Third Conference on the Biology of Normal and Atypical Pigment Cell Growth
    • 1st Edition
    • Myron Gordon
    • English
    Pigment Cell Growth covers the proceedings of the Third Conference on the Biology of Normal and Atypical Pigment Cell Growth. The book focuses on the nature of the pigment cell and its contained melanin. The selection first offers information on the origin of the mammalian pigment cell and its role in the pigmentation of hair and relations between developing melanophores and embryonic tissues in the Mexican axolotl. The book also examines the genetic control of pigmentation in the fowl; relationship of atypical pigment cell growth to gonadal development in hybrid fishes; and estrogen, thyroid hormone, and the differentiation of pigment cells in the brown leghorn. The publication takes a look at dendritic melanoblasts in metastatic squamous cell carcinoma; microscopic analysis of normal melanoblasts, nevus cells, and melanoma cells; and analysis of skin color in living human subjects by spectrophotometric means. The selection is a dependable source of data for readers interested in pigment cell growth.

A chapter is devoted to the arterial blood gases and rheumatoid disease. Another section focuses on the functional effects and treatment of diffuse fibrosing alveolitis. The book can provide useful information to scientists, doctors, students, and researchers.
  • Water Relations in Membrane Transport in Plants and Animals

    • 1st Edition

    • English
    Water Relations in Membrane Transport in Plants and Animals contains the presentations in a symposium dealing with Water Relations in Membranes in Plants and Animals, during the 27th Annual Fall Meeting of the American Physiological Society held at The University of Pennsylvania, 17-19 August 1976. The purpose of the symposium was to explore the common modes of water regulation in plants and animals. In these proceedings, the mechanisms employed to restrict water flow across plant and metazoan animal cells are described. Putative differences in mechanisms of water regulation retained by plant versus animal cells become inconsequential in the light of the numerous similarities: dependence upon bioelectric potentials maintained across cell membranes, energy dependence of uphill water movement, and solute coupling during water transport. The presentations can be organized into four. The first takes up specific mechanisms of water transport in plants. The second and third parts deal with specific mechanisms in invertebrates and vertebrates, respectively. The fourth part covers generalized mechanisms common to plants and animals.
