Book Description
This text provides readers with an in-depth exploration of how biological control functions and how it can be safely employed to solve pest problems and enhance nature conservation. It covers the principles behind biological control techniques and their implementation, and incorporates practical examples from the biological control of a variety of pests. It contains detailed chapters on conserving natural enemies through environmental management, importation of new natural enemies for control of pests, augmentation of natural enemies through rearing and release, and the development and application of pathogens and biopesticides.

Book Description
A complex pile of Tertiary volcanic rocks in the central San Juan Mountains, Colo., consists of welded ash-flow tuffs, lava flows, and breccias from several sources. A more limited sequence within this assemblage originated in or bordering the Creede caldera and is the subject of this report. The Creede caldera sequence consists of five major ash-flow formations, locally interlayered lava flows, a succeeding lava-flow formation, and the volcanic-clastic Creede Formation.

Book Description
Modern Power Station Practice, Volume 5: Chemistry and Metallurgy focuses on power station chemistry and metallurgy. The book first offers information on power station chemistry, including the use, preparation, sampling, storage, and transport of coal to power stations. Other considerations include the commercial use of ash, analysis and testing of coal and coke, gas-side cleaning of boilers, oil firing, burner fuels, testing of fuel oils and gases, and air pollution. The text also reviews water treatment relative to the operation of boilers. The corrosion of metals; sampling and analysis of feed water, boiler water, and steam; instrumentation for quality control; and on-load corrosion of boilers are discussed. The book also looks at cooling water systems in water treatment plants. Topics include water softening, evaporators, sources and quality of raw water, demineralization, and boiler feed water composition. The text also gives emphasis to plant cleaning and inspection and metallurgy and welding. The book is a valuable reference for readers interested in power station chemistry and metallurgy.
