  • The Rumen and Its Microbes

    • 1 Edición
    • Robert E. Hungate
    • Inglés
    The Rumen and Its Microbes is a contribution to the ecology of this important microbial habitat. Relatively few microbial habitats have been subjected to a thorough quantitative ecological analysis. The rumen fermentation is peculiarly suitable because of its relatively constant and continuous nature and because of the very rapid rates of conversion of organic matter. Although analysis of the ruminant-microbe symbiosis is still far from complete, knowledge is sufficient for formulation of principles and for identification and measurement of important parameters. The first eight chapters of the book include a description of the rumen and its microbes, their activities, and the extent of these activities. This basic biology provides a framework in which applications to agriculture can be evaluated. These applications are discussed in the last four chapters: host metabolism, variation in the rumen, possible practical applications, and abnormalities in rumen function.

    Poulsson’s Text-Book of Pharmacology and Therapeutics, Second English Edition covers the considerable progress in understanding the basic principles, applications, and classifications of drugs and other organic compounds of therapeutic interest. This text is divided into six chapters, each dealing with a specific classification of drugs. The first chapter describes the so-called protoplasmic poisons, which are organic substances that are characterized by their specific effects after absorption on the nervous and muscular systems, while local effects are altogether absent or insignificant. The second chapter examines the organic remedies that principally act locally, such as at the point of application, while the action after absorption is unimportant or is not utilized in medicine. The third and fourth chapters explore the main groups containing the inorganic bodies. These chapters demonstrate that the inorganic compounds differ from the organic, whose activity is due to the unchanged entire molecules, and they are subjected to dissociation. The fifth chapter considers the digestive ferments and foodstuffs, while the sixth chapter is concerned with antitoxins and bacterial products. This book will be of value to pharmacologists, pharmacists, researchers, and pharmacology and pharmacy students.

    • Inglés
    The Principal Diseases of Lower Vertebrates presents the material published by Heinz H. Reichenbach-Klinke between 1957 and 1962 in three separate volumes as ""Krankheiten der Aquarienfische"" (Alfred Kernen, Stuttgart), ""Krankheiten der Amphibien,"" and ""Krankheiten der Reptilien"" (Gustav Fischer, Stuttgart). The scope of the work has been enlarged with material contributed by E. Elkan who has also done the translation. Representatives of the main groups of parasites affecting fish have been presented as far as possible. The book is organized into three parts covering the diseases of fishes, amphibians, and reptiles. Experience has shown that those who keep, or are interested in, one kind of lower vertebrate will sooner or later also take an interest in one of the other groups. It was therefore thought expedient to include what is at present known of lower vertebrate pathology in one volume, even at the risk of some repetition where fishes, amphibians, and reptiles suffer from similar diseases or are the victims of identical parasites.

  • The Value of Agricultural Land

    • 1 Edición
    • Colin Clark
    • Inglés
    The Value of Agricultural Land is concerned with the value of agricultural land and covers topics ranging from land rents, transport costs, and land use as well as land prices and agricultural rents. This book has seven chapters; the first of which discusses the principles underlying the value of agricultural land, with emphasis on rent and the views of David Ricardo. The next chapter focuses on Von Thünen’s theory of rents, transport costs, and land use. In particular, it examines Von Thünen’s argument that transport costs were the cause, and rents the consequence, of important differentiations of agricultural, dairy, and forest production, according to distance from the market. The use of production functions and programming to estimate the marginal productivity of land is then explained, along with agricultural rents actually paid in different countries and periods. This book concludes with an analysis of prices of land in relation to ""residual incomes."" Agricultural economists and policymakers will find this book extremely helpful.
