Book Description
The purpose of this report is to present an assessment of several alternatives to distillation as a means of separating ethanol from fermentation beers. Process flowsheets, capital and operating cost summaries, and energy requirements are presented. Each process is assessed in terms of nearness to commercial adaptability and ranked according to energy-efficiency and cost using a state-of-the art distillation process for comparison.

Book Description
Preliminary evaluation indicates that separation of ethanol and water can be accomplished with less energy than is now needed in conventional distillation processes. The state of development for these methods varies from laboratory investigation to commercially available processes. The processes investigated were categorized by type of separation depending on their ability to achieve varying degrees of ethanol/water separation. The following methods were investigated: ethanol extraction with CO2 (the A.D. Little process); solvent extraction of ethanol; vacuum distillation; vapor recompression distillation; dehydration with fermentable grains; low temperature blending with gasoline; molecular sieve adsorption; and reverse osmosis.

Book Description
A major problem of conventional economic theory as applied to long-run economic change is its unduly narrow and static character, which compromises its capacity to handle conceptually a social process inherently systemic, complex and dynamic. At the same time there is a growing realization in relevant government and industrial circles (reinforced by the example of Japan) that effective economic policy-making needs a strategic, and therefore a technological, content. Long-Run Economics suggests a more realistic conceptual framework for the analysis of economic and technological change. Borrowing from other disciplines, such as sociology, psychology and biology, the authors develop a model that is evolutionary and systemic in character. Special emphasis is given to the role of information flows in the innovative process, while the overall argument is illustrated by two case studies, photovoltaics and fuel ethanol. Finally, the book stresses the strategic importance of science and technology policy and the role of appropriate institutions in facilitating long-run economic change.

Book Description
A Guide to the World of the Yeasts J. F. T. Spencer and D. M. Spencert As the well-known authority on yeasts, the late Professor Rose, frequently pointed out, it is impossible for one person to present, in a single volume, the details of the life, composiotion, habitats, relationships, and actual and potential uses to man kind of the 500 (at last count) known species of yeasts. This book confirms the truth of this statement. However, our aim is actually more modest than that, and this book is an attempt to introduce the general reader, and possibly some inter ested specialists, to the lives of the yeasts in their natural and more artificial habitats, their use by human beings, and to give some idea of the wonderfully complex activities within the yeast cell, the characteristics of the metabolism and molecular biology of yeasts, and the applications of these characteristics to life in the present-dayworld ofhuman existence. The book proceeds from a brief chapter on what is and is not known of the origins and early history of the yeasts, through a description of their classification, relationships, habitats and general life style, their external morphology and internal structures and mechanisms within their cells, the regulatory mechanisms controlling processes such as signal transmis sion, mating, cell fusion, and many others.
