Economic evaluation of the MIT process for manufacture of ethanol
This report summarizes the results of an economic evaluation of the MIT process for the manufacture of ethanol from cellulosic residues. Conceptual process designs were developed for two cases, Case A which is based on the experimental data obtained to date, and Case B which hypothesizes the suppression of acid byproducts. Manufacturing costs, including profit, were estimated at $12.20/million Btu for Case A and $9.40/million Btu for Case B. These are equivalent to about $1.05 and $0.80/gal ethanol respectively. These economic estimates may be slightly on the low side since they do not consider feedstock storage nor working capital requirements. Nevertheless, the manufacturing costs for Case A appear to be comparable to those of the manufacture of ethanol from corn. The plant size used for this analysis was 1500 ton/day corn stover. This is considered to be a realistic size. The conceptual plants make about 27 million gal/yr ethanol in Case A and 41 million gal/yr in Case B. The MIT process appears to be one of the more promising programs being developed under contract for DOE. It is recommended that the process research be continued. Three areas of concern were identified which must be investigated before the process can …

Foreign Medical Schools: Education Should Improve Monitoring of Schools That Participate in the Federal Student Loan Program
A letter report issued by the Government Accountability Office with an abstract that begins "Each year, the federal government makes a significant financial investment in the education and training of the U.S. physician workforce. A quarter of that physician workforce is composed of international medical graduates (IMG) and they include both U.S. citizens and foreign nationals. In fiscal year 2008, the federal government loaned $633 million to U.S. students enrolled in foreign institutions--including medical students--through the Federal Family Education Loan (FFEL) program. The government also makes a substantial domestic investment in the graduate training of the physician workforce. For example, in fiscal year 2008, federal support for residency training in the United States amounted to nearly $9 billion. As with medical students educated in the United States, this training is required of all IMGs--U.S. citizens and foreign nationals alike--who seek to practice medicine without supervision in the United States. The Department of Education (Education), which administers the federal student loan program, must also monitor foreign schools that seek to participate in the program with respect to specific statutory requirements. Among these is the statutory requirement that at least 60 percent of their students who take the U.S. medical licensing exam …

Community Investment: Los Angeles's Use of a Community Development Block Grant Exemption
Correspondence issued by the General Accounting Office with an abstract that begins "Under the Department of Housing and Urban Development's (HUD) Community Development Block Grant (CDBG) program, entitlement communities--also called grantees--receive funds that they can spend to support specific community development activities, such as rehabilitating housing, improving public facilities, and providing public services. Most grantees are prohibited by statute from spending more than 15 percent of their CDBG funding on public service activities, such as child care, health care, and crime prevention. However, in the aftermath of the 1992 Los Angeles civil unrest, Congress gave an exemption from this statutory cap to two grantees--the City of Los Angeles and the County of Los Angeles--allowing them to spend up to 25 percent of their funds on public services. In December 2001, the exemption was extended through 2003. Between 1993 and 2001, the City of Los Angeles spent between 20 and 25 percent of its CDBG funding to support public service activities, while the County of Los Angeles spent between 9 and 20 percent. According to HUD data for 1999 through 2001, the city and county used a majority of their public service funding to support general public services and either youth …

Building Partner Capacity: Actions Needed to Strengthen DOD Efforts to Assess the Performance of the Regional Centers for Security Studies
A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Defense's (DOD) five Regional Centers for Security Studies (Regional Centers) share similarities and differences with other DOD institutions that provide training and education, including professional military education, advanced degree-conferring, and professional development institutions, in terms of curriculum topics, targeted audience, and program format. GAO found that they all offer training and educational programs and activities to help participants understand security and military matters and to enhance their knowledge, skills, and experiences in these matters. However, there are notable differences in that the Regional Centers generally focus on helping foreign participants understand and respond to regional security issues; generally target a foreign civilian and military personnel audience; and offer shorter and typically less formal courses of study. The Regional Centers support DOD policy objectives with curricula designed to enhance security and foster partnerships through education and exchanges. By contrast, other DOD training and education organizations focus their curricula on military operations and leadership. While the Regional Centers' target audience is foreign civilian and military officials, the other DOD educational organizations typically aim their programs and activities at U.S. servicemembers at all career levels.

Advanced Amine Solvent Formulations and Process Integration for Near-Term CO2 Capture Success
This Phase I SBIR project investigated the economic and technical feasibility of advanced amine scrubbing systems for post-combustion CO2 capture at coal-fired power plants. Numerous combinations of advanced solvent formulations and process configurations were screened for energy requirements, and three cases were selected for detailed analysis: a monoethanolamine (MEA) base case and two “advanced” cases: an MEA/Piperazine (PZ) case, and a methyldiethanolamine (MDEA) / PZ case. The MEA/PZ and MDEA/PZ cases employed an advanced “double matrix” stripper configuration. The basis for calculations was a model plant with a gross capacity of 500 MWe. Results indicated that CO2 capture increased the base cost of electricity from 5 cents/kWh to 10.7 c/kWh for the MEA base case, 10.1 c/kWh for the MEA / PZ double matrix, and 9.7 c/kWh for the MDEA / PZ double matrix. The corresponding cost per metric tonne CO2 avoided was 67.20 $/tonne CO2, 60.19 $/tonne CO2, and 55.05 $/tonne CO2, respectively. Derated capacities, including base plant auxiliary load of 29 MWe, were 339 MWe for the base case, 356 MWe for the MEA/PZ double matrix, and 378 MWe for the MDEA / PZ double matrix. When compared to the base case, systems employing advanced solvent formulations and …

Heats of Formation of Triplet Ethylene, Ethylidene, and Acetylene
Heats of formation of the lowest triplet state of ethylene and the ground triplet state of ethylidene have been predicted by high level electronic structure calculations. Total atomization energies obtained from coupled-cluster CCSD(T) energies extrapolated to the complete basis set limit using correlation consistent basis sets (CBS), plus additional corrections predict the following heats of formation in kcal/mol: Delta H0f(C2H4,3A1) = 80.1 at 0 K and 78.5 at 298 K, and Delta H0f(CH3CH,3A") = 86.8 at 0 K and 85.1 at 298 K, with an error of less than +-1.0 kcal/mol. The vertical and adiabatic singlet-triplet separation energies of ethylene were calculated as Delta ES-T,vert = 104.1 and Delta ES-T,adia = 65.8 kcal/mol. These results are in excellent agreement with recent quantum Monte Carlo (DMC) values of 103.5 +- 0.3 and 66.4 +- 0.3 kcal/mol. Both sets of computational values differ from the experimental estimate of 58 +- 3 kcal/mol for the adiabatic splitting. The computed singlet-triplet gap at 0 K for acetylene is Delta ES-T,adia(C2H2) = 90.5 kcal/mol, which is in notable disagreement with the experimental value of 82.6 kcal/mol. The heat of formation of the triplet is Delta H0f(C2H2,3B2) = 145.3 kcal/mol. There is a systematic underestimation of …

Low-level detection and quantification of Plutonium(III, IV, V,and VI) using a liquid core waveguide
Understanding the aqueous chemistry of plutonium, in particular in environmental conditions, is often complicated by plutonium's complex redox chemistry. Because plutonium possesses four oxidation states, all of which can coexist in solution, a reliable method for the identification of these oxidation states is needed. The identification of plutonium oxidation states at low levels in aqueous solution is often accomplished through an indirect determination using series of liquid-liquid extraction procedures using oxidation state specific reagents such as HDEHP and TTA. While these methods, coupled with radioactive counting techniques provide superior limits of detection they may influence the plutonium redox equilibrium, are time consuming, waste intensive and costly. Other analytical methods such as mass spectrometry and radioactive counting as stand alone methods provide excellent detection limits but lack the ability to discriminate between the oxidation states of the plutonium ions in solution.

Direct observation of photoinduced bent nitrosyl excited-state complexes
Ground state structures with side-on nitrosyl ({eta}{sup 2}-NO) and isonitrosyl (ON) ligands have been observed in a variety of transition-metal complexes. In contrast, excited state structures with bent-NO ligands have been proposed for years but never directly observed. Here we use picosecond time-resolved infrared spectroscopy and density functional theory (DFT) modeling to study the photochemistry of Co(CO){sub 3}(NO), a model transition-metal-NO compound. Surprisingly, we have observed no evidence for ON and {eta}{sup 2}-NO structural isomers, but have observed two bent-NO complexes. DFT modeling of the ground and excited state potentials indicates that the bent-NO complexes correspond to triplet excited states. Photolysis of Co(CO){sub 3}(NO) with a 400-nm pump pulse leads to population of a manifold of excited states which decay to form an excited state triplet bent-NO complex within 1 ps. This structure relaxes to the ground triplet state in ca. 350 ps to form a second bent-NO structure.

Electronic Properties of LiFePO4 and Li doped LiFePO4
The potential use of different iron phosphates as cathodematerials in lithium-ion batteries has recently been investigated.1 Oneof the promising candidates is LiFePO4. This compound has severaladvantages in comparison to the state-of-the-art cathode material incommercial rechargeable lithium batteries. Firstly, it has a hightheoretical capacity (170 mAh/g). Secondly, it occurs as mineraltriphylite in nature and is inexpensive, thermally stable, non-toxic andnon-hygroscopic. However, its low electronic conductivity (~;10-9 S/cm)results in low power capability. There has been intense worldwideresearch activity to find methods to increase the electronic conductivityof LiFePO4, including supervalent ion doping,2 introducingnon-carbonaceous network conduction3 and carbon coating, and theoptimization of the carbon coating on LiFePO4 particle surfaces.4Recently, the Li doped LiFePO4 (Li1+xFe1-xPO4) synthesized at ARL hasyield electronic conductivity increase up to 106.5 We studied electronicstructure of LiFePO4 and Li doped LiFePO4 by synchrotron based soft X-rayemission (XES) and X-ray absorption (XAS) spectroscopies. XAS probes theunoccupied partial density of states, while XES the occupied partialdensity of states. By combining XAS and XES measurements, we obtainedinformation on band gap and orbital character of both LiFePO4 and Lidoped LiFePO4. The occupied and unoccupied oxygen partial density ofstates (DOS) of LiFePO4 and 5 percent Li doped LiFePO4 are presented inFig. 1. Our experimental results clearly indicate …

Self-induced rainout from a nuclear weapon
The conclusions we have reached are that rainout of fresh radioactive debris occurred at Hiroshima and Nagasaki, that this precipitation was initiated either by the weapon itself or by the ensuing fires or by both, and that self-induced rainout can occur and deposit sufficient amounts of radioactivity on the ground to pose a significant collateral damage hazard.

Differential Thermal Analysis of Uranium Tetrafluoride-Uranium Dioxide Mixtures
Abstract: "Approximate melting points have been determined for five samples of uranium tetrafluoride representing incompletely converted uranium dioxide and covering the range from about 2 to 20 w/o UO2, using the method of differential thermal analysis. The results indicate the melting temperatures are in the range of 920 to 980 C. No significant correlation between melting point and UO2 content was observed, possibly because of calcite formation. Similar results were obtained on synthetic mistakes of UF4 containing from 10 to 40 w/o UO2."
