    • Inglés
    Economics of Food Processing in the United States aims to provide an economic overview of the food processing industries in the United States; to explore the firm-level implications of social, economic, technological, and institutional forces for selected food processing industries; and to uncover some of the implications for consumers, raw product producers, and the national economy of the major trends observed in food industries. The book begins by evaluating the major forces shaping demand, supply, prices, and trade in processed foods. It then considers major trends in technical processes; major forces in marketing, distribution, and structure; and major trends in regulation. The next few chapters explore these trends for five specific food processing industries, which represent major types of products processed: fruits and vegetables, meat, milk, grain and soybeans, and wine. After the specific industries have been examined, the final two chapters treat these industries in the context of the national and international economy. Students preparing for careers, researchers, and industry participants who study these firms and industries and the various approaches to solving their economic and management problems will benefit from the information in this volume and from its approach to presenting the dynamics of the food processing industries.

    • Alec Rickard + 3 más
    • Inglés
    Owing to man-made intervention, the shrub-steppe now represents a rapidly disappearing landscape in the arid regions of North America. This book represents a systems-level study of ecological variables affecting water balance, and responses to perturbation. The study focused on a very large, protected, landscape unit, comprising a natural ``watershed'' area located in the semi-arid western United States. Long-term and concurrent data sets were established with a view towards establishing system-level responses to manipulative interventions, and natural perturbations like wildfire. These data sets were established for micrometeorology, climatology, mineral cycling in soils, nutrient and mineral pathways in springs and streams, vegetational dynamics, and population changes on the site. In synthesizing nearly twenty years of data, the more interesting ecosystem level responses concerned vegetational recovery and water balance. For instance, the synthesis uniquely demonstrates the interaction of biotic and non-biotic factors and their integrated effect on regional water balance. However, special attention was also paid to species diversity and the genetic resource pool represented at this site.This book will be of primary interest as a reference resource to land managers and wildlife specialists, and as a research study for scientists interested in systems-level ecology. Conservation-minded citizens who take more than a cursory interest in ecology will also find it interesting.

    Feeding and Nutrition of Nonhuman Primates is a report of a two-day meeting that aims to evaluate the knowledge and information regarding the diet of primates. The meeting also aims to recommend significant information necessary to accomplish a standardized diet for this species. The study of primates' diet is relevant, because it will serve as baseline data for biomedical research. Comprised of 16 chapters, this volume starts off with the concept of selecting nonhuman primates in the biological research. The next topics are about the observations regarding the feeding behavior of the nonhuman primates and their nutritional status. Also discussed are the feeding problems encountered by imported primates. Other problem areas in the subject of diet and nutrition are also discussed, such as the effect of altering the dietary amino acids on the nutrition of a rhesus monkey and malnutrition during early life. The following chapters describe the nutritional requirements of nonhuman primates including macaque monkeys, Cebus monkeys, squirrel and woolly monkeys, marmosets, and baboons. The observations regarding their feeding behavior are also discussed. Topics regarding nutritional deficiency diseases as well as their syndromes and diseases affecting their usefulness in nutrition research are also covered in this book. This compilation of research is a relevant resource for professionals, scientists, and researchers in primate studies and biological/biomedica... research.

    • Inglés
    Rodent Malaria reviews significant findings concerning malaria parasites of rodents, including their taxonomy, zoogeography, and evolution, along with life cycles and morphology; genetics and biochemistry; and concomitant infections. This volume is organized into eight chapters and begins by sketching out the history of the discovery of rodent as well as aspects of parasitology, immunology, and chemotherapy. These concepts are investigated two decades following Ignace Vincke's major discovery and Meir Yoeli's successful establishment of the method of cyclical transmission of the parasite. The following chapters focus on the taxonomy and systematics of the subgenus Vinckeia, with reference to the concepts of species and subspecies of animals and the degree to which they apply to malaria parasites, in particular to those of rodents. The discussion then shifts to how the rodent malaria parasites provide a unique insight into the subcellular organization of Plasmodium species, the use of rodent malaria as an experimental model to study immunological responses, and infectious agents that interact with malaria parasites. The book concludes with a chapter on malaria chemotherapy, with emphasis on the value of rodent malaria in antimalarial drug screening and the use of antimalarial drugs as biological probes. This book will be of interest to protozoologists and physicians as well as those from other disciplines including biochemistry, immunology, pharmacology, cell biology, and genetics.

    • Inglés
    Perspectives on Plant Competition is mainly about addressing the many different perspectives in plant competition and finding a common ground among them. Its aim is that through this common ground, new theories can be created. Encompassing 20 chapters, this book is divided into three parts. Part I, Perspectives on the Determinants of Competitive Success, consists of eight chapters. This section deals mainly on the question of determination of competitive success. Different writers put forward various definitions of competition and competitive success to shed light on the question at hand. In the second part of this book, an opposing set of views regarding the consequences of competitive interactions for the plant community structure is provided. This section emphasizes the idea that competition is not the sole force in natural communities. Each chapter in this part focuses on a certain aspect of competition as seen in different communities – across and within habitats – and systems. Part III, which comprises of four chapters, focuses on the competition within the context of interaction of plants with organisms on the other trophic levels. The chapters set forth the idea that competition depends on the impacts of herbivores, parasites, and symbionts. The concluding part of the book greatly emphasizes the need to integrate the mechanisms of competition into the framework of the entire food web.
