A recently developed coda magnitude methodology was applied to selected broadband stations in Turkey for the purpose of testing the coda method in a large, laterally complex region. As found in other, albeit smaller regions, coda envelope amplitude measurements are significantly less variable than distance-corrected direct wave measurements (i.e., L{sub g} and surface waves) by roughly a factor 3-to-4. Despite strong lateral crustal heterogeneity in Turkey, we found that the region could be adequately modeled assuming a simple 1-D, radially symmetric path correction for 10 narrow frequency bands ranging between 0.02 to 2.0 Hz. For higher frequencies however, 2-D path corrections will be necessary and will be the subject of a future study. After calibrating the stations ISP, ISKB, and MALT for local and regional distances, single-station moment-magnitude estimates (M{sub w}) derived from the coda spectra were in excellent agreement with those determined from multi-station waveform modeling inversions of long-period data, exhibiting a data standard deviation of 0.17. Though the calibration was validated using large events, the results of the calibration will extend M{sub w} estimates to significantly smaller events which could not otherwise be waveform modeled due to poor signal-to-noise ratio at long periods and sparse station coverage.

The mobilization of arsenic was examined in a system where the deposition of iron and arsenic have been substantially modified by large-scale manipulations. This engineering practice was designed to decrease arsenic concentrations in water supplied to the City of Los Angeles. Accomplishing this objective, however, has resulted in significant accumulation of arsenic and iron in the sediments of a reservoir on the Los Angeles Aqueduct. Arsenic and iron are released into the porewater at depth in the sediment, consistent with reductive dissolution of iron(III) oxyhydroxides. Factors influencing the possible re-sorption of arsenic onto residual iron(III) oxyhydroxides solids have been examined. Reduction of As(V) to As(III) alone cannot account for arsenic mobilization since arsenic occurs in the solid phase as As(III) well above the depth at which it is released into the porewater. Competition from other porewater constituents could suppress re-sorption of arsenic released by reductive dissolution.

A stable estimate of the earthquake source spectra in the western Alps is obtained using an empirical method based on coda envelope amplitude measurements described by Mayeda et al. (2003) for events ranging between M{sub W} {approx} 1.0 to {approx}5.0. We calibrated path corrections for consecutive narrow frequency bands ranging between 0.2 and 25.0-Hz using a simple 1-D model for 5 three-component stations of the Regional Seismic network of Northwestern Italy (RSNI). The 1-D assumption performs well, even though the region is characterized by a complex structural setting involving strong lateral variations in the Moho depth. For frequencies less than 1.0-Hz, we tied our dimensionless, distance-corrected coda amplitudes to an absolute scale in units of dyne-cm by using independent moment magnitudes from long-period waveform modeling for 3 moderate magnitude events in the region. For the higher frequencies, we used small events as empirical Green's functions, with corner frequencies above 25.0-Hz. For each station, the procedure yields frequency-dependent corrections that account for site effects, including those related to f{sub max}, as well as those related to S-to-coda transfer function effects. After the calibration was completed, the corrections were applied to the entire data-set composed of 957 events. Our findings using the …

Testimony issued by the General Accounting Office with an abstract that begins "Following the terrorist attacks of September 11, 2001, the Bush administration developed and published seven national strategies that relate, in part or in whole, to combating terrorism and homeland security. These were National Security Strategy of the United States of America; National Strategy for Homeland Security; National Strategy for Combating Terrorism; National Strategy to Combat Weapons of Mass Destruction; National Strategy for the Physical Protection of Critical Infrastructure and Key Assets; National Strategy to Secure Cyberspace; and the 2002 National Money Laundering Strategy. In view of heightened concerns about terrorism and homeland security, GAO was asked to identify and define the desirable characteristics of an effective national strategy and to evaluate whether the national strategies related to terrorism address those characteristics. The purpose of this testimony is to report on GAO's findings on this matter."

In this paper we propose a novel visibility-culling technique for optimizing the computation and rendering of opaque isosurfaces. Given a continuous scalar field f (x) over a domain D and an isovalue w, our technique exploits the continuity of f to determine conservative visibility bounds implicitly, i.e., without the need for actually computing the isosurface f{sup -1}(w). We generate Implicit Occluders based on the change in sign of f *(x) = f (x)-w, from positive to negative (or vice versa) in the neighborhood of the isosurface. Consider, for example, the sign of f * along a ray r cast from the current viewpoint. The first change in sign of f * within D must contain an intersection of r with the isosurface. Any additional intersection of the isosurface with r is not visible. Implicit Occluders constitute a general concept that can be exploited algorithmically in different ways depending on the framework adopted for visibility computations. In this paper, we propose a simple from-point approach that exploits well-known hardware occlusion queries.

Separating the metals from the glass is the first step in recycling end-of-life cadmium telluride photovoltaic modules and manufacturing scrap. We accomplished this by leaching the metals in solutions of various concentrations of acids and hydrogen peroxide. A relatively dilute solution of sulfuric acid and hydrogen peroxide was found to be most effective for leaching cadmium and tellurium from broken pieces of CdTe PV modules. A solution comprising 5 mL of hydrogen peroxide per kg of PV scrap in 1 M sulfuric acid, gave better results than the 12 mL H{sub 2}O{sub 2}/kg, 3.2 M H{sub 2}SO{sub 4} solution currently used in the industry. Our study also showed that this dilute solution is more effective than hydrochloric-acid solutions and it can be reused after adding a small amount of hydrogen peroxide. These findings, when implemented in large-scale operation, would result in significant savings due to reductions in volume of the concentrated leaching agents (H{sub 2}SO{sub 4} and H{sub 2}O{sub 2}) and of the alkaline reagents required to neutralize the residuals of leaching.

A Monte Carlo method for the estimation of {beta}-delayed {gamma}-ray spectra following fission is described that can accommodate an arbitrary time-dependent fission rate and photon collection history. The method invokes direct sampling of the independent fission yield distributions of the fissioning system, the branching ratios for decay of individual fission products and the spectral distributions for photon emission for each decay mode. Though computationally intensive, the method can provide a detailed estimate of the spectrum that would be recorded by an arbitrary spectrometer, and can prove useful in assessing the quality of evaluated data libraries, for identifying gaps in these libraries, etc. The method is illustrated by a first comparison of calculated and experimental spectra from decay of short-lived fission products following the reactions {sup 235}U(n{sub th}, f) and {sup 239}Pu(n{sub th}, f). For general purpose transport calculations, where detailed consideration of the large number of individual {gamma}-ray transitions in a spectrum may be unnecessary, it is shown that an accurate and simple parameterization of a {gamma}-ray source function can be obtained. These parametrizations should provide high-quality average spectral distributions that should prove useful in calculations describing photons escaping from thick attenuating media.

The National Museum of the Pacific War presents an oral interview with Tom Anderson. Anderson dropped out of college in 1941 and hitchhiked from Texas to San Diego. There he worked for Consolidated Aircraft, drafting plans for the B-32, B-36, and C-99. He then transferred to the Fort Worth plant, where he stayed until 1944, when he enlisted in the Navy. He was selected for radar technician training, and after boot camp he studied electronics in Chicago, followed by airborne radar training in Corpus Christi. He had a lifelong interest in flying and looked forward to his first duty assignment. But when the war ended in Japan, his radar conning class was cancelled and he was reassigned to the radar shop of CASU-5 at the Naval Air Station in San Diego. Anderson was discharged into the Armed Guard in March 1946, taking up work at the Fiscal and Disbursement Office of the Adjutant General at Camp Mabry. In 1950 he returned to school and joined the Army Reserves, retiring in 1966 as a lieutenant colonel.
