The use of photoelectron spectroscopy, primarily x-ray photoelectron spectroscopy, to obtain information on the electronic structure of a wide variety of solids (especially the bulk electronic structure of solids) is covered. Both valence band and core-level spectra, as well as a few cases of photon excited Auger electron spectroscopy, are employed in the investigations to derive information on N(E). The effect of several modulations inherent in the measured I(E)'s, such as final state band structure, cross section, and relaxation, is discussed. Examples of many-electron interactions in PES are given. Some experimental aspects of PES and AES studies are given with emphasis on sample preparation techniques. Multiple splitting of core levels is examined using the Mn levels in MnF/sub 2/ as a detailed case study. Core level splittings in transition metals, rare earth metals, transition metal halides and several alloys are also reported. The application of PES to the study of the chemical bond in some crystalline semiconductors and insulators, A/sup N/B/sup 8-N/ and A/sup N/B/sup 10-N/ compounds is treated, and a spectroscopic scale of ionicity for these compounds is developed from the measured ''s-band'' splitting in the valence band density of states.

This monograph deals with the properties of Alfven waves and with their application to fusion. The book is divided into 7 chapters dealing with linear properties in homogeneous and inhomogeneous plasmas. Absorption is treated by means of kinetic theory. Instabilities and nonlinear processes are treated in Chapters 1 to 6, and the closing chapter is devoted to theory and experiments in plasma heating by Alfven waves. (MOW)

A letter report issued by the Government Accountability Office with an abstract that begins "How to fund public television has been a concern since the first noncommercial educational station went on the air in 1953. The use of federal funds to help support public television has been a particular point of discussion and debate. This report reviews (1) the organizational structure of public television, (2) the programming and other services that public television provides, (3) the current funding sources for public television, (4) the extent to which public television stations are increasing their nonfederal funding sources and developing new sources of nonfederal support, and (5) the extent to which public television benefits financially from business ventures associated with programming and how this compares with commercial broadcasters. GAO reviewed revenue, membership, and programming data for all public television licensees. GAO also interviewed officials from 54 of public television's 173 licensees, the Corporation for Public Broadcasting, the Public Broadcasting Service, federal agencies, and producers of commercial and public television programming"

This report discusses the unique characteristics that may dictate that government programs in support of broadband deployment be structured differently than conventional infrastructure programs.

Part I of the report discusses how the meaning of “the press” has expanded from printed material to include a wide range of broadcast and electronic media. Satellites, computers, electronic bulletin boards, teletex, videotext, and other new ways of gathering, editing, and delivering news are blurring legal and regulatory distinctions between common carriers and “the press, ” thus changing arguments about the constitutional rights that they have each enjoyed. Part II addresses freedom of speech and press as they apply to scientific communications and technological know-how. As science and technology become ever more important to our economy and our military strength, the delicate balance between individual rights and the national interest becomes both more important and more difficult to maintain.

On the 20th anniversary of the first lunar landing mission, Apollo 11, President Bush outlined a program that would put the United States on an aggressive track to return to the Moon to stay, and to land humans on Mars. The president's space policy calls for expanding human presence an activity beyond Earth orbit into the Solar System; obtaining scientific, technological and economic benefits for the American people; encouraging private sector participation in space; improving the quality of life on the Earth; strengthening national security; and promoting international cooperation in space. The Space Exploration Initiative accomplishes these goals. In August 1989, NASA began an extensive review to summarize the technology and strategies for going back to the Moon and on to Mars. To obtain the final objective, major topical activities were defined. These activities were incremental capabilities to be achieved to fulfill the national space vision. They include: (1) moon waypoints (lunar exploration; preparation for mars; habitation; lunar based observation; fuels; energy to earth); (2) asteroids waypoints; and (3) mars waypoints. The six national space vision are (1) to increase our knowledge of solar system and beyond; (2) to rejuvenate interest in Science and engineering; (3) to refocus the US …

This article provides a broad overview of the Human Genome Project, with particular emphasis on work being done at Los Alamos. It tries to emphasize the scientific aspects of the project, compared to the more speculative information presented in the popular press. There is a brief introduction to modern genetics, including a review of classic work. There is a broad overview of the Genome Project, describing what the project is, what are some of its major five-year goals, what are major technological challenges ahead of the project, and what can the field of biology, as well as society expect to see as benefits from this project. Specific results on the efforts directed at mapping chromosomes 16 and 5 are discussed. A brief introduction to DNA libraries is presented, bearing in mind that Los Alamos has housed such libraries for many years prior to the Genome Project. Information on efforts to do applied computational work related to the project are discussed, as well as experimental efforts to do rapid DNA sequencing by means of single-molecule detection using applied spectroscopic methods. The article introduces the Los Alamos staff which are working on the Genome Project, and concludes with brief discussions on ethical, …
