  • Urea as a Protein Supplement

    • 1st Edition
    • Michael H. Briggs
    • English
    Urea as a Protein Supplement presents the significant advances that have been made in ruminant nutrition. This book examines the role of the rumen flora and fauna as synthesizers of protein from non-protein nitrogen sources such as ammonium compounds and urea. Organized into four parts encompassing 23 chapters, this book starts with an overview of the use of urea and other non-protein nitrogen sources in ruminant nutrition. This text then explores the various methods that may be used for the preparation of urea, which involves the dehydration of ammonium carbamate produced by the reaction of carbon dioxide and ammonia at high pressure and temperature. Other chapters consider the ways in which urea could be utilized to increase protein supplies. The final chapter deals with the hydrolysis of urea by urease to ammonia and carbon dioxide, which has been used as a method for determining urea for many years. Agricultural scientists and farmers will find this book useful.

  • Measurements for Stresses in Machine Components

    • 1st Edition
    • V. F. Yakovlev + 1 more
    • English
    Measurements for Stresses in Machine Components focuses on the state of stress and strain of components and members, which determines the service life and strength of machines and structures. This book is divided into four chapters. Chapter I describes the physical basis of several methods of measuring strains, which includes strain gauges, photoelasticity, X-ray diffraction, brittle coatings, and dividing grids. The basic concepts of the electric strain gauge method for measuring stresses inside machine components are covered in Chapter II. Chapter III elaborates on the results of experimental work on stresses and strains in linear, plane, and three-dimensional states of stress under static load conditions. The last chapter is devoted to examples for experimental stress analysis of plane and three-dimensional states of stresses under dynamic loads. Conclusions drawn from the theoretical and experimental investigations discussed in this text are provided at the end. This publication is intended for engineers and technicians, but is also a good reference for students researching on the stress or strains of machine components.

  • Primitive Money

    In its Ethnological, Historical and Economic Aspects
    • 2nd Edition
    • Paul Einzig
    • English
    Primitive Money: In its Ethnological, Historical and Economic Aspects: Second Edition, Revised and Enlarged deals with the study of the role of money in the past and in selected regions of the world. This selection is divided into three sections, designated as Book I, Book II, and Book III. Book I discusses the ethnology of money extending back to more than 5,000 years ago, to the dark age when not much written evidence existed, and to today's various communities scattered around the world. The text covers the regions of Oceania, Asia, Africa, and the Americas. Book II looks into the historical aspect of money, from the ancient period comprising prehistoric currencies such as tools and ornaments, to the Medieval period, and then to modern times. Book III is the theoretical section that attempts to define primitive money, its functions, and its perceived value. This book applies something modern when it discusses primitive monetary policy, such as active and passive attitudes of the State, restrictionist policy, stabilizationist policy, and expansionist monetary policy. This section also discusses the philosophy of primitive money, and its economic and historical roles. The change from primitive to modern money is examined, and the future prospects such as the continuance or redemption of primitive money is discussed. Anthropologists, sociologists, economists, historians, students and academicians doing sociological research, and even businessmen and industrialists can benefit from reading this text.

  • Society, Schools and Progress in Scandinavia

    The Commonwealth and International Library: Education and Educational Research
    • 1st Edition
    • Willis Dixon
    • Edmund King
    • English
    Society, Schools and Progress in Scandinavia is one of a mutually supporting series of books on SOCIETY, SCHOOLS AND PROGRESS in a number of important countries or regions. Society, schools, and progress are here surveyed in the world's most significant countries not simply for reasons of technological or political strength, but because of the widely relevant decisions in education now being taken. The present volume is intended to give students and other persons interested in Scandinavia sufficient information and comment to begin to understand the contemporary scene in Denmark, Norway, and Sweden. The book opens with an overview of Scandinavia—its geography, social policy and welfare, politics and administration, and tradition and contemporary policy. This is followed by separate chapters on education in Denmark, Norway, and Sweden, covering administration, the school system, family influences, and background social forces. The final chapter presents an evaluation of progress and change in Scandinavia.

  • Mechanisms of Release of Biogenic Amines

    Proceedings of an International Wenner-Gren Center Symposium Held in Stockholm, February 1965
    • 1st Edition
    • U. S. Von Euler + 2 more
    • English
    Wenner-Gren Center International Symposium Series, Volume 5: Mechanisms of Release of Biogenic Amines provides information pertinent to the fundamental aspects of the release of biogenic amines. This book discusses the physiology, biochemistry, and pharmacology of the biogenic amines. Organized into 39 chapters, this volume begins with an overview of the release of amines, which is implicated in functional disturbances characteristic of different diseases. This text then examines the concepts of cell structure that are significant to the release of neurohumoral agents. Other chapters consider the fluorescence reaction, which made it possible to work out a practical histochemical procedure. This book describes as well a few examples in which the monoaminergic transmitter is not revealed as a diffuse cytoplasmic fluorescence. The final chapter deals with acetylcholine as the only brain amine investigated, which could be influenced by the tremorgenic agents during the period of tremor. This book is a valuable resource for biochemists, morphologists, pharmacologists, and physiologists.

    Education and Social Change provides a basic introduction to educational studies, with a viewpoint for decision. This book discusses the increasing number of educational influences at work outside the schools and colleges. Organized into three parts encompassing 10 chapters, this book starts with an overview of the influences affecting the schools as well as affecting the entire life in which the schools have to take on a different meaning. This text then examines the educational institutions and describes how their purposes, structures, and populations are undergoing unprecedented change. Other chapters deal with the transformation of the teaching–learning role itself, with reference to the teachers. This book discusses as well the relevance of all educational sciences. The final chapter briefly examines some of the main questions that need to be asked again because of all the changes in education's purposes and instrumentality. This book is a valuable resource for students and teachers.
