Applied Process Design for Chemical and Petrochemical Plants: Volume 2

"It is important that scientists think about and know their history - where they came from, what they have accomplished, and how these may affect the future. Weed scientists, similar to scientists in many technological disciplines, have not sought historical reflection. The technological world asks for results and for progress. Achievement is important not, in general, the road that leads to achievement. What was new yesterday is routine today, and what is described as revolutionary today may be considered antiquated tomorrow. Weed science has been strongly influenced by technology developed by supporting industries, subsequently employed in research and, ultimately, used by farmers and crop growers. The science has focused on results and progress. Scientists have been--and the majority remain--problem solvers whose solutions have evolved as rapidly as have the new weed problems needing solutions. In a more formal sense, weed scientists have been adherents of the instrumental ideology of modern science. That is an analysis of their work, and their orientation reveals the strong emphasis on practical, useful knowledge; on know how. The opposite, and frequently complementary orientation, that has been missing from weed science is an emphasis on contemplative knowledge; that is, knowing why. This book expands on and analyzes how these orientations have affected weed sciences development. Key Features. The first analytical history of weed science to be written. Compares the development of weed science, entomology and plant pathology. Identifies the primary founders of weed science and describes their role"

"Integrated Pest Management: Current Concepts and Ecological Perspective presents an overview of alternative measures to traditional pest management practices using biological control and biotechnology. The removal of some highly effective broad-spectrum chemicals, caused by concerns over environmental health and public safety, has resulted in the development of alternative, reduced risk crop protection products. These products, less toxic to the environment and easily integrated into biological control systems, target specific life stages or pest species. Predation recognized as a suitable, long-term strategy effectively suppresses pests in biotechnological control systems. Integrated Pest Management covers these topics and more. It explores the current ecological approaches in alternative solutions, such as biological control agents, parasites and predators, pathogenic microorganisms, pheromones and natural products as well as ecological approaches for managing invasive pests, rats, suppression of weeds, safety of pollinators, role of taxonomy and remote sensing in IPM and future projections of IPM. This book is a useful resource to entomologists, agronomists, horticulturists, and environmental scientists. Key Features. Fills a gap in the literature by providing critical analysis of different management strategies that have a bearing on agriculture, sustainability and environmental protection. Synthesizes research and practice on integrated pest management. Emphasizes an overview of management strategies, with critical evaluation of each in the larger context of ecologically based pest management"

"Postharvest Handling: A Systems Approach introduces a new concept in the handling of fresh fruits and vegetable. Traditional treatments have been either physiologically based with an emphasis on biological tissue or technologically based with an emphasis on storage and handling. This book integrates all processes from production practices through consumer consumption with an emphasis on understanding market forces and providing fresh product that meets consumer expectations. Postharvest physiologists and technologists across the disciplines of agricultural economics, agricultural engineering, food science and horticulture along with handlers of minially-processed products within the fresh produce fruit and vegetable processing industries will find this to be an invaluable source of information. Key Features

Resource Structure of Agriculture: An Economic Analysis focuses on the quantitative economic analysis of the agricultural industry. The book first discusses the theory of resource demand. Topics include decision milieu in agriculture; aggregate demand for an input; and notes on the statistical estimation of the demand function for an input. The text also examines the role of labor in agriculture, including agricultural wages, migration from agriculture, and regional labor supply. The monograph underscores the use of machineries in the agricultural sector. Analysis of post-war demand for power and machinery; early developments in agricultural mechanization; trends in the use of other machinery; and supply conditions for agricultural machinery are discussed. The text also looks at the use of fertilizers and pesticides in the agricultural sector, as well the need to invest in farm buildings. The book examines the demand for resources and supply of agricultural products. Future pattern of resource use and technological change; interactions between demands for different resources; and resource demand and a derived supply elasticity are discussed. The text is a valuable source of data for readers interested in the economic analysis of the agricultural industry.

"Following the successful first edition, this revised edition, contains 680 pages and 900 color photos and diagrams, covering every imaginable symptom, pest and disease affecting the tomato. This is the definitive work on the diseases and disorders of the tomato, a worldwide crop of significant economic importance. Key Features. Includes over 300 high quality colour photographs. Explains how to examine and identify diseases of the foliage, roots, neck, stalk and fruit. Enables readers to diagnose and combat both parasitic and non-parasitic diseases of the tomato plant and fruit"
