    • David Forsyth
    • Inglés
    How Life Began: A Speculative Study in Modern Biology is a seven-chapter text that covers some broad and wide conceptions about biological life origin. The opening chapters deal with the significant biological research on comprehensive interpretation of the human body and the beginning of primal germinal existence of Homo sapiens. These chapters also look into the influence of heredity and environment on human origin. These topics are followed by a presentation of the idea that biological life is a universal phenomenon. The discussion then shifts to the evolutionary aspect of human life existence. The concluding chapters describe the concept of life struggle for existence and the associated idea of the species survival of the fittest. Biologists, evolutionists, and research workers who are interested in the issue of life beginning and existence will find this book invaluable.

    Principles of Epidemiology: A Self-Teaching Guide consists of a series of problem-solving exercises designed to introduce and guide readers toward an understanding of the principles and methods of epidemiology, rather than the epidemiology of specific diseases or subject areas such as ""infectious disease"" or ""chronic disease"" epidemiology. The guide has been formulated to be used by itself or as a supplement to standard textbooks. It illustrates and illuminates the principles and concepts of epidemiology and provides the reader an opportunity to practice the application of these principles in a logical sequence. The guide is divided into 14 exercises. Each exercise will help readers to understand principles or methods used by epidemiologist. Topics covered include the patterns of disease, populations at risk and risk assessment, screening for disease, investigation of an epidemic, etiology of disease, principles of causation, study design in epidemiologic investigation, data interpretation, and the uses and applications of epidemiology.

    • Inglés
    Eutrophication of Deep Lakes focuses on research and experiments that are deemed valuable to mitigate the eutrophication of lakes. Containing the contributions of authors who have continuously conducted studies in this field, the book proceeds by pointing out how the loading concept can serve as a basis in the control of eutrophication. This discussion is seconded by discussions on the factors affecting the eutrophication of freshwaters in Norway. Particularly given attention in this book is the phosphorous content of small and large lakes. The relationship of pollution and eutrophication is also noted. The large inputs of nutrients into lakes is emphasized, and then the application of the US OECD eutrophication study results to deep lakes is discussed. The book also points to the stage of eutrophication of lakes in Norway, and particularly concerns the effect of eutrophication on living organisms in lakes. A review of the toxic substances that affect these organisms is also presented. The text is a valuable source of information for researchers and readers who are interested in studying how eutrophication affects the natural composition of lakes; how this process affects life in lakes; and the control measures and processes that need to be taken to control it.

    • Inglés
    Comparative Vertebrate Morphology provides a comprehensive discussion of vertebrate morphology. The structure-function concept at the level of organs and organ systems is fundamental to an understanding of comparative evolutionary morphology. It is upon these three interrelated aspects—structure, function, and evolution— that that contents of this volume have been organized and presented. The book opens with a discussion of general concepts on vertebrate evolution. This is followed by separate chapters on vertebrate phylogeny, skeletal components, the cranial and postcranial skeleton, muscular tissues, muscular system, and development of the integument, nervous tissues, sense organs, nervous system structure, nervous pathways, and endocrines. Subsequent chapters deal with the digestive, respiratory, circulatory, excretory and water balance, and reproductive systems. This book was designed to meet the needs of a one-semester course for students who have already had an introductory course in biology. It is assumed that the lectures will be supplemented by a laboratory with its own laboratory manual. The organization of the text allows the instructor to coordinate the laboratory and lecture portions of the course.

    A Neurological Study of Newborn Infants considers the consistencies and inconsistencies of neonatal neurological signs. The possibility of a relationship between pre- and perinatal complications of pregnancy and later cerebral dysfunction has led to an increasing interest in the early detection of these defects in the newborn infant. This book is divided into nine chapters, and begins with a presentation of standardized procedures to obtain reliable information from the neurological examination. The next chapters deal with the developmental course of neurological signs during the first days of life. The final chapters discuss the potential effects of obstetrical and postnatal conditions on the developmental course and the consistency of neurological signs throughout the neonatal period. This book is an invaluable source for developmental biologists, neurologists, pediatricians, and obstetricians.

  • Plant Virology

    • R. E. F. Matthews
    • Inglés
    Plant Virology, Second Edition, was written to cover the substantial developments in many areas of plant virology since the first edition was published. Advances have been made in all branches of the subject, but these have been most far reaching with respect to the structure of viruses and of their components, and in the understanding of how viral genomes are organized and how viruses replicate in cells. Significant developments have also occurred in the understanding of how viruses are transmitted by invertebrates and in the application of control measures for specific diseases. The taxonomy of viruses has advanced significantly, and there are now 25 internationally approved families and groups of plant viruses. All these developments have required that most sections be entirely rewritten. This book is intended primarily for graduate students in plant pathology, plant virology, general virology, and microbiology, and for teachers and research workers in these fields. It should also prove useful to some people in related disciplines—molecula... biologists, biochemists, plant physiologists, and entomologists.
