The most important factor in limiting the stability of dye-sensitized solar cells is the use of volatile liquid solvents in the electrolytes, which causes leakage during extended operation especially at elevated temperatures. This, together with the necessary complex sealing of the cells, seriously hampers the industrial-scale manufacturing and commercialization feasibilities of DSSCs. The objective of this program was to bring about a significant improvement in the performance and longevity of dye-based solar cells leading to commercialization. This had been studied in two ways first through development of low volatility solid, gel or liquid electrolytes, second through design and fabrication of TiO2 sculptured thin film electrodes.

A low energy neutrino factory (LENF) is defined, for the purpose of this report, to accelerate a muon beam to a total energy in the range of 10-14 GeV, and store it in a decay ring directing a resulting neutrino beam to a detector 2200-2300 km distant. The machine should be ultimately capable of producing 10{sup 21} decays toward that detector per year of 10{sup 7} s. We consider such a neutrino factory to be the accelerator defined in the Interim Design Report (IDR) of the International Design Study for the Neutrino Factory (IDS-NF), modified to remove the final stage of acceleration, possibly modifying the remaining acceleration stages to adjust the final energy, and replacing the decay ring with one designed for the lower energy and shorter baseline. We discuss modifications to that design which would reduce the cost of the machine at the price of a reduction in neutrino production, down to as low as 10{sup 20} decays per year. These modifications will not preclude eventually upgrading the machine to the full production of 10{sup 21} decays per year. The eventual cost of a machine which achieves the full production through a series of lower-production stages should not exceed …

Taking a bottom-up approach, this report examines seven primary drivers of wind turbine prices in the United States, with the goal of estimating the degree to which each contributed to the doubling in turbine prices from 2002 through 2008, as well as the subsequent decline in prices through 2010 (our analysis does not extend into 2011 because several of these drivers are best gauged on a full-year basis due to seasonality issues). The first four of these drivers can be considered, at least to some degree, endogenous influences – i.e., those that are largely within the control of the wind industry – and include changes in: 1) Labor costs, which have historically risen during times of tight turbine supply; 2) Warranty provisions, which reflect technology performance and reliability, and are most often capitalized in turbine prices; 3) Turbine manufacturer profitability, which can impact turbine prices independently of costs; and 4) Turbine design, which for the purpose of this analysis is principally manifested through increased turbine size. The other three drivers analyzed in this study can be considered exogenous influences, in that they can impact wind turbine costs but fall mostly outside of the direct control of the wind industry. These …

Intracellular Dynamics of Energy-Transducing Organelles. The location and interaction of intracellular organelles is important for exchange of substrate and product between compartments for optimum functioning of biochemical pathways and energy transduction. Plastids and stromules, tubular plastid extensions, are highly dynamic in many plant tissues. Stromules can connect two or more plastids and proteins and macromolecular complexes can be transferred between them. Stromules have been observed to form close contacts with other organelles, the plasma membrane, and can pass through channels in the nucleus. Chloroplasts move in response to light and mechanical stimulus. Especially in non-green cells, plastids change shape and position, and stromules extend and retract. Stromules appear to be involved in recycling of chloroplast proteins when photosynthesis is limited, through an autophagic process that results in degradation of portions of the stromal contents without complete destruction of the chloroplast. Mutations in several genes known to mediate chloroplast division result in altered stromule morphology in some cells. Plastid and stromule motility is mediated by the actin cytoskeleton. The possible role of myosins in chloroplast movement was investigated by labeling the cargo-binding tails of six Arabidopsis myosin XI proteins with yellow fluorescent protein (YFP). The fluorescent proteins were found to localize …

The iButton is a 'one-wire', temperature sensor and data logger in a short metal cylinder package 17 mm in diameter and 6 mm tall. The device is designed to be attached to a surface and acquire temperature samples over time periods as short as 1 second to as long as 300 minutes. Both 8-bit and 16-bit samples are available with 8kB of memory available. Lifetime is limited to an internal battery that cannot be replaced or recharged. The RF test interest originated with the concern that the data logger could inadvertently record electrical emanations from other nearby equipment. The normal operation of the data logger does not support high speed sampling but the control interface will operate at either 15.4 kbps or 125 kbps. There were no observable effects in the operation of the module or in the data that could be attributed to the use of RF energy. They made the assumption that these devices would potentially show RF sensitivity in any of the registers and in the data memory equally, therefore gross changes in the data might show RF susceptibility. No such sensitivity was observed. Because significant power levels were used for these tests they can extrapolate downward …

A solid object, such as a simplified approximation to an implosion core defined by the 17% intensity contour, can be described by a sum of spherical harmonics, following the notation of Butkov (Mathematical Physics, ISBN 0-201-00727-4, 1968; there are other notations so care is required), with Pl(x) being the usual (apparently standard) Legendre polynomial. For the present purposes, finding the volume and surface area of an implosion core defined by P0, P2, P4, M0, and M4, I will restrict the problem to consider only A{sub 00}, A{sub 20}, A{sub 40}, and A{sub 44}, with the phase angle set to eliminate the sin(m{phi}) term. Once the volume and surface area are determined, I will explore how these coefficients relate to measured quantities A0, A2/A0, A4/A0, M0, and M4/M0.

The National Museum of the Pacific War presents an oral interview with Evan Riley. Riley was born in Nashville, Tennessee 5 September 1921. At a very young age, he and his four siblings were placed into an orphanage and he tells of growing up during the Depression. Joining the US Army in 1942, he was selected to attend Officer Candidate School and graduated as a second lieutenant in 1943. He then received training in the tank corps at Fort Knox, Kentucky. After spending several months at Camp Cooke, California, he requested a transfer to an Airborne unit. He was accepted and sent to Fort Benning, Georgia where he transferred from being a tank officer to being an infantry officer. Upon completing his paratroop training he joined the 511th Parachute Infantry Regiment of the 11th Airborne Division on Luzon in June 1945. The unit was on Okinawa preparing for the invasion of Japan when Japan surrendered. On 28 August 1945 the unit landed at Atsugi, Japan as a part of the Occupation forces. He was then sent to Sendai where he served for nine months before returning to Fort Bragg, North Carolina. Following the end of World War II, Riley remained …
