The Regional Resource Centers for Innovation (RRCIs) promote networking among the various regional, state, and local specialists who provide services to inventors and small business innovators. This networking facilitates the rapid deployment of I&I technologies that provide solutions for the energy challenges facing the U.S.

The Salt Lake metropolitan area faces some interesting economic and environmental challenges. It ranks eighth in the nation in population growth, so managing its increasing numbers without spoiling the beauty of its high mountain valley may seem to be a contradiction in goals. In addition, the 2002 Winter Olympics will attract almost 2 million visitors during February, when Salt Lake's unusual topography encourages its highest levels of air pollution. The Clean Cities Coalition is working with the Salt Lake Olympic Organizing Committee to find clean vehicles to transport visitors to and from the various Olympic venues. A major goal of the Coalition is to keep as many AFVs as possible in Utah after the Olympics.

Interview with Mary Jane Dellinger. The interview includes Dellinger's personal experiences about working as a riveter at Armstrong Cork and Rubber Company during World War II, and assembling time fuses for bombs at the Hamilton Watch Company. Dellinger also talks about pre-war work experience in silk mills, effects of the Great Depression on her family, her marriage to Clair Dellinger, personal motivations for seeking defense work, her decision to change jobs and work for Armstrong Cork and Rubber Company, her work on the F4U Corsair fuselage assembly line, sexual harassment, production incentives and awards, war bond drives, shift work, transportation arrangements, and her decision to quit.

Caporaso, Barletta and Neil (CBN) found in a solution to the problem of the single-bunch beam breakup in a linac[1]. However, their method applies only to the case of a beam traveling in a strongly betatron-focused linac under the influence of the resistive wall impedance. We suggest in this paper a method for dealing with the same problem. Our methods is more general; it applies to the same problem under any impedance, and it applies to a linac with or without external betatron focusing.

Solar Electricity--The Power of Choice (formerly NREL PV Working With Industry) is a quarterly newsletter devoted to the research and development activities performed by NREL staff in concert with their industry and university partners. This issue is devoted to NREL's renewables workshop for farmers and ranchers, presented at the National Western Stock Show in Denver; the PV Industry Roadmap; the Siemens Solar Industries celebration of 200 MW of cumulative PV module production; and a profile of ''PV Beyond the Horizon'' initiative. The editorialist for this issue is Tim Anderson of the University of Florida.

This fact sheet describes what was newly added to the AFDC and Clean Cities (and other DOE) Web sites.

The National Renewable Energy Laboratory's Solar Energy Research Facility in Golden, Colorado, uses a stair-step configuration to allow daylight and heat into the office areas, while the laboratories in the back of the building are in a more controlled environment where tight levels of ventilation, humidity, temperature, and light are critical. A unique mechanical system makes the most of the natural environment and the building's design to efficiently heat and cool the building at an annual utility bill savings of almost $200,000 per year.

Radiation can damage cellular components, including DNA. Organisms have developed a panoply of means of dealing with DNA damage. Some repair paths have rather narrow substrate specificity (e.g. photolyases), which act on specific pyrimidine photoproducts in a specific type (e.g., DNA) and conformation (double-stranded B conformation) of nucleic acid. Others, for example, nucleotide excision repair, deal with larger classes of damages, in this case bulky adducts in DNA. A detailed discussion of DNA repair mechanisms is beyond the scope of this article, but one can be found in the excellent book of Friedberg et al. [1] for further detail. However, some DNA damages and paths for repair of those damages important for photobiology will be outlined below as a basis for the specific examples of genetic and molecular analysis that will be presented below.

Organisms living on the earth are exposed to solar radiation, including its ultraviolet (UV) components (for general reviews, the reader is referred to Smith [1] and Young et al. [2]). UV wavelength regions present in sunlight are frequently designated as UVB (290-320 nm) and UVA (320-400 nm). In today's solar spectrum, UVA is the principal UV component, with UVB present at much lower levels. Ozone depletion will increase the levels of UVB reaching the biosphere, but the levels of UVA will not be changed significantly [3]. Because of the high efficiency of UVB in producing damage in biological organisms in the laboratory experiments, it has sometimes been assumed that UVA has little or no adverse biological effects. However, accumulating data [4, 5], including action spectra (efficiency of biological damage as a function of wavelength of radiation; see Section 5) for DNA damage in alfalfa seedlings [6], in human skin [7], and for a variety of plant damages (Caldwell, this volume) indicate that UVA can induce damage in DNA in higher organisms. Thus, understanding the differential effects of UVA and UVB wavebands is essential for estimating the biological consequences of stratospheric ozone depletion.

Application of high pressure significantly alters the interatomic distance and thus the nature of intermolecular interaction, chemical bonding, molecular configuration, crystal structure, and stability of solid [1]. With modern advances in high-pressure technologies [2], it is feasible to achieve a large (often up to a several-fold) compression of lattice, at which condition material can be easily forced into a new physical and chemical configuration [3]. The high-pressure thus offers enhanced opportunities to discover new phases, both stable and metastable ones, and to tune exotic properties in a wide-range of atomistic length scale, substantially greater than (often being several orders of) those achieved by other thermal (varying temperatures) and chemical (varying composition or making alloys) means. Simple molecular solids like H{sub 2}, C, CO{sub 2}, N{sub 2}, O{sub 2}, H{sub 2}O, CO, NH{sub 3}, and CH{sub 4} are bounded by strong covalent intramolecular bonds, yet relatively weak intermolecular bonds of van der Waals and/or hydrogen bonds. The weak intermolecular bonds make these solids highly compressible (i.e., low bulk moduli typically less than 10 GPa), while the strong covalent bonds make them chemically inert at least initially at low pressures. Carbon-carbon single bonds, carbon-oxygen double bonds and nitrogen-nitrogen triple bonds, for example, …

Characterizing an adaptive optics (AO) system refers to understanding its performance and limitations. The goal of an AO system is to correct wavefront aberrations. The uncorrected aberrations, called the residual errors and referred to in what follows simply as the errors, degrade the image quality in the science camera. Understanding the source of these errors is a great aid in designing an AO system and optimizing its performance. This chapter explains how to estimate the wavefront error terms and the relationship between the wavefront error and the degradation of the image. The analysis deals with the particular case of a HartmannShack wavefront sensor (WFS) and a continuous deformable mirror (DM), although the principles involved can be applied to any AO system.

Interview with accountant and Army veteran William Barsanti. The interview includes Barsanti's personal experiences about the European Theater during World War II, his youth in an Italian immigrant family, graduating from high school and enrolling in college, then in the Enlisted Reserve Corps, being inducted into the U.S. Army, basic training, being selected for the Army Specialized Training Program, transferring to the 106th Infantry Division, and his assignment to Cannon Company as a supply sergeant. Barsanti also talks about the living conditions at Stalag XII-A and Stalag II-D, Stargard, Germany, evacuating to Bremervorde, Germany, liberation, and his postwar business career in Europe.
