The Office of Technology Assessment is currently preparing an assessment of energy from biological processes. In the course of this study we have carried out an extensive analysis of alcohol fuels from agricultural products. This technical memorandum presents these findings in response to congressional interest in synthetic fuels. The purpose of the memorandum is to illuminate the technical and non-technical issues surrounding the development of gasohol. It discusses the resource base, production technologies, and economics of gasohol, and its use as a transportation fuel. The report also contains a discussion of the environmental problems and benefits of producing and using gasohol, and the social and institutional issues about using agricultural products for energy.While the memorandum does not present an analysis of policy issues, it does provide estimates of how much gasohol can be used at what cost, and the long-term prospects for ethanol production. All are important to the current congressional debate over development of a gasohol policy.
The history of initial actions in a war contains lessons of special value for the professional soldier and for all students of military problems. Northwest Africa abounds in such lessons, for it covers the first massive commitments of American forces in World War II. The continent of Africa became a gigantic testing ground of tactics, weapons, and training evolved through years of peace. The invasion stretched American resources to the limit. Simultaneously the country was trying to maintain a line of communications to Australia, to conduct a campaign at Guadalcanal, to support China in the war against Japan, to arm and supply Russia's hard-pressed armies on the Eastern Front, to overcome the U-boat menace in the Atlantic, to fulfill lend-lease commitments, and to accumulate the means to penetrate the heart of the German and Japanese homelands. The Anglo-American allies could carry out the occupation of Northwest Africa only by making sacrifices all along the line. Two campaigns occurred there: Operation TORCH which swiftly liberated French North Africa from Vichy French control, followed by a longer Allied effort to destroy all the military forces of the Axis powers in Africa. The latter concentrated in Tunisia, where the front at one time extended more than 375 miles, and fighting progressed from scattered meeting engagements to the final concentric thrust of American, British, and French ground and air forces against two German and Italian armies massed in the vicinity of Bizerte and Tunis. The planning, preparation, and conduct of the Allied operations in Northwest Africa tested and strengthened the Anglo-American alliance. Under General Dwight D. Eisenhower a novel form of command evolved which proved superior to adversities and capable of overwhelming the enemy. Richard W. Stephens Maj. Gen., U.S.A. Chief of Military History
Few people intentionally consider durability when designing a home, but rather rely on experience and market acceptance to make design decisions. This approach to design works best in a stable housing market where architectural preferences and material choices do not change or change very slowly. The housing market, however, tends to be dynamic rather than stable and new materials and preferences influence the market continuously, sometimes in dramatic ways. This dynamic condition also places a responsibility on designers and builders to properly apply their experiences, which are often based on older construction methods and materials, to new materials and design conditions. As a result, it is important to understand why certain practices have been effective (or ineffective) in the past so that they can be properly interpreted and considered in the design and construction of modern homes. Durability by Design: A Guide for Residential Builders and Designers is intended to raise the awareness and understanding of building durability as a design consideration in housing. The Guide covers basic concepts of durability and presents recommended practices -including numerous construction details and design data- for matters such as moisture management, ultraviolet (UV) protection, insects, decay, corrosion, and natural hazards. Some attention is also given to matters that may be considered serviceability issues related to normal wear-and-tear, aesthetics, or functions not immediately associated with durability. The contents of this Guide will help to preserve and promote "tried-and-true" practices and concepts related to housing durability, and present them in a manner that can be used to cost-effectively design the durable homes of the future.
These tales have their scenes laid in Silesia and Bohemia. For centuries they have come down in the shape of tradition from generation to generation. Silesia, the land of their birth, has had an eventful history. Originally a part of Poland, it was drawn under the influence of the German king, Frederick Barbarossa, about 1163. Many names of places suggest that the original population was Celtic. For four centuries it was almost continuously under the domination of Bohemia. It was annexed to that country about 1472. It was finally added to Prussia by Frederick the Great. Bohemia derives its name from a Celtic tribe. It forms the borderline between the German and Slavonic races. Rübezahl, the hero of these tales is a spirit prince and exercises supreme authority over all other gnomes in his district. He is superior to them in many particulars. What his real appearance is no one really knows. He can make himself so beautiful that Apollo is ugly in comparison. On the other hand, he may, and he often does, assume an appearance so terrible that old women hurriedly mutter a fervent prayer, brave men take to flight, and young maidens sink in unconsciousness. His character is as changeable as his form.
This history of the Burbages, The Globe Theatre and the early staging of Shakespeare's plays is based on a lifetime of research into the role of the Burbage family in the Elizabethan theater, especially in Shakespeare productions. This work remains indispensable, especially for its extracts from contemporary sources detailing the plays produced, the actors, controversies of the time, censorship, other acting companies, and much else.This title is cited and recommended by the Cambridge Bibliography of English Literature.
A documented and highly charged contemporary indictment of the Belgian exploitation of Africa during the height of the imperialistic age, first published in 1906 with the support of British antislavery organizations. This expose, by a horrified British investigator, of the atrocities committed against the natives of the Congo by soldiers in the employ of King Leopold of Belgium has an introduction by Sir Harry H. Johnston.This title is cited and recommended by The American Historical Association's Guide to Historical Literature.

Approximately 20 million Americans work some form of nonstandard work schedule. These schedules, which require that an individual work during nondaytime hours, noncontinuous hours, or for extended periods, are referred to as "shift work." Recent advances in the understanding of the biological rhythms of the body and their control by the brain indicate that shift work can disrupt these rhythms, with possible adverse consequences for the worker. This report is the third in a series of OTA studies being conducted under an assessment of "New Developments in Neuroscience." It was requested by the House Committees on Appropriations; Energy and Commerce; Science, Space, and Technology; Veterans Affairs; and the Senate Subcommittee on Science, Technology, and Space of the Committee on Commerce, Science, and Transportation. The report discusses biological rhythms: what they are, how they are controlled by the brain, and the role they play in regulating physiological and cognitive functions. The major focus of the report is the examination of the effects of nonstandard work hours on biological rhythms and how these effects can interact with other factors to affect the health, performance, and safety of workers. In addition, the report describes the Federal regulatory framework related to work hours and the current status of biological rhythm and shift work research. The report presents a range of options for congressional action related to the amount of research being conducted on these topics, the collection of relevant workplace statistical data, and the congressional role in ensuring the well-being of individuals engaged in nonstandard hours of work.
Pharmaceutical costs are among the fastest growing components of health care costs today. Although increases in the inflation-adjusted prices of ethical drugs and perceived high prices of new drugs have been a concern of congressional committees for over 30 years, the growing Federal role in paying for prescription drugs has increased the concern over the appropriateness of prices relative to the costs of bringing new drugs to market. Specific policies of U.S. and other governments can alter the delicate balance between costs and returns to pharmaceutical R&D, with ramifications for the future health of Americans, for health care costs, and for the future of the U.S. pharmaceutical industry. OTA's report focuses mainly on the economic side of the R&D process. Pharmaceutical R&D is an investment, and the principal characteristic of an investment is that money is spent today in the hopes of generating even more money in the future. Pharmaceutical R&D is a risky investment; therefore, high financial returns are necessary to induce companies to invest in researching new chemical entities. Changes in Federal policy that affect the cost, uncertainty and returns of pharmaceutical R&D may have dramatic effects on the investment patterns of the industry. Given this sensitivity to policy changes, careful consideration of the effects on R&D is needed. The specific request for this study came from the House Committee on Energy and Commerce and its Subcommittee on Health and the Environment. The Senate Committee on the Judiciary's Subcommittee on Antitrust, Monopolies, and Business Rights endorsed the study. OTA was assisted in this study by an advisory panel of business, consumer, and academic leaders chaired by Frederick M. Scherer, Ph.D., Professor of Economics, John E Kennedy School of Government at Harvard University. OTA gratefully acknowledges the contribution of each of these individuals. As with all OTA reports, the final responsibility for the content of the assessment rests with OTA.
This manual contains the engineering tools and concepts that have proven useful in planning, constructing, and maintaining drainage systems for successful long-term irrigation projects. The manual is not a textbook. Mathematical and experimental development of the engineering tools has generally not been included. Indeed, not even all the innovative ways to use the tools are included. The manual provides drainage engineers a ready reference and guide for making accurate estimates of drainage requirements. Design and construction criteria, if followed with reason, will result in reliable drainage systems for irrigated areas.All the methods and techniques covered in the manual have proven to be very satisfactory through observed field conditions on irrigated lands throughout the world. Some methods have a more elegant development and basis in science than others, but all have been designed to solve practical problems in the field.
This book describes briefly some of the methods frequently employed for the propagation of deciduous fruit trees as well as a number of the trees and shrubs used for the adornment of home grounds. Practical details concerning the care and handling of tree seeds, the culture of seedlings, the successive steps in the handling of cuttings, layers, grafts, and buds in order to succeed in these operations, as well as the methods of propagation most suitable for the several kinds of woody plants, are presented.

CONTENTSThe Moral Obligation to Be Intelligent,The Call to Service,The Mind of Shakespeare,Magic and Wonder in Literature In different ways the four essays set forth one theme -- the moral use to which intelligence might be put, in rendering our admirations and our loyalties at once more sensible and more noble. At the time of original publication in 1915, John Erskine, Ph.D., was Associate Professor of English at Columbia University.
When Francis Bacon wrote the New Atlantis in the early 17th century, he envisioned a state-supported research institution in which knowledge could be applied to 'enlarge the bounds of Human Empire, to the effecting of all things possible." Among the research facilities to increase the protection and material comforts of the inhabitants of his imaginary island, Bacon imagined an Engine House to study all types of motion, including flight. National aeronautical research laboratories in Europe and the United States in the early 20th century reflected Bacon's vision of science applied to the practical problems of flight. Commitment to innovation accompanied Bacon's belief in progress. His utopia honored inventors, not politicians or academics.In 1941 the same commitment to innovation and industrial progress won federal funding for a laboratory in Cleveland, Ohio. Local and national leaders expected the new laboratory to promote innovations in aircraft engine technology to help win the war against Germany. Contributions to the development of superior engines for military and passenger aircraft after World War II justified the large federal investment in research facilities and personnel. Today this laboratory is the NASA Lewis Research Center. In contrast to the isolation of the ideal research institution of Bacon's vision, Lewis took shape in a flesh-and-blood world of personalities, national security concerns, and postwar capitalism.Two transitions, both precipitated by advances in propulsion technology, provide the structure for my history: the revolution in jet propulsion during World War II, and the launch of Sputnik in October 1957. Each had significant national political, military, and economic repercussions. Each forced the laboratory to restructure its research program and to redefine its relationships with its three constituencies--the military, industry, and academia. Within this framework I have distinguished one theme that recurs throughout the laboratory's history--the tension between fundamental or basic research and development. In the process of writing my history I found that these terms could not be defined in any absolute sense. Their meaning is enmeshed in the history of Lewis, and the definitions of research and development changed as Lewis evolved. As an institution, Lewis engaged in a continuing reevaluation of its role within the American propulsion community and, after the formation of NASA in 1958, within a vastly expanded federal bureaucracy.
This guide has been written by experts in the field to provide you, a consumer, with information about the use of solar energy to heat the water you use in your home. It is no secret that energy costs have been rising rapidly in the past several years, and that conventional sources of energy are in short supply.As more and more people feel the impact of the rising cost and limited availability of some types of energy, increasing attention is being given to the energy available in sunlight. No longer just a fad for some individual experimenters, no longer only a subject for scientific and engineering studies, solar energy applications are now a matter of intense interest to almost everyone.Of all of the ways in which we can capture and use solar energy to meet our needs, providing hot water is perhaps the simplest and most economical for the homeowner. Many manufacturers now make equipment and systems to provide solar-heated water, and many firms around the country are qualified to install, maintain, and service them. The Federal government and several states even provide tax credits to help cover the cost of solar energy systems.But deciding to buy and install a solar hot water system still requires you to consider a number of factors---whether the system will save you money now or in the future, what kind of system to buy and from whom to buy it, whether to install it yourself or have it installed, and similar matters. This guide is designed to provide some of the information you will need to make these decisions, and to tell you where to get the rest of the information you may need to install or have installed a satisfactory solar hot water system.
Since the invention of the Bushnell Keg in 1776, mine warfare has been an important element of naval warfare. The use of mines and countermeasures to mines has figured significantly in every major armed conflict and nearly every regional conflict in which the United States has been involved since the Revolutionary War. Mine warfare has been increasingly important and effective since World War I. Mines presently on the world arms markets are relatively inexpensive, easy to procure, reliable and effective, and difficult for intelligence agencies to track. The mine, as a weapon system, has an extremely favorable investment return (cost of mine to cost of damage ratio) for the miner. Despite the logic and effectiveness of maintaining the mine element of war at sea on an even footing with the other naval warfighting specialties, throughout its history, the U.S. Navy has devoted proportionally fewer resources to mine warfare. As a result, despite the emergence of the U.S. Navy as the world's premier maritime power whose individual warfighting capabilities generally are superior to those of other navies, its mine countermeasure capabilities have lagged behind. The old adage that those who will not learn the lessons of history are doomed to repeat them has persistently applied to the mine warfare aspect of the U.S. Navy. North Arabian Gulf operations of the U.S. Navy in Desert Storm contain some bitter experiences, including the mission-aborting mine strikes to two major warships, as well as the controversy over the decision not to land U.S. Marines in Kuwait. Despite the unfortunate nature of the initial Desert Storm experience and the need to recapture expertise in MCM, the U.S. Navy and Allied navies did have substantial success in countering the nearly 1,300 naval mines deployed by the Iraqis and emerged victorious in the MCM element of Desert Storm warfighting as in the other aspects of that war. This positive conclusion to the mine clearance campaign in the North Arabian Gulf was because of the unparalleled material and logistics support from the Department of the Navy's shore establishment and the cooperation of many allied nations in the coalition effort. In addition to national support and multinational cooperation, the enabling elements of this success were the ability of the American Bluejacket to learn and adapt quickly, combined with good tactical command in the fields. Of special note is that as the course of the mine clearance campaign progressed, the Naval Component Command leadership came to understand, appreciate, and support the complex warfighting nature of mine clearance operations.
