Advanced Hydrogen Transport Membranes for Vision 21 Fossil Fuel Plants (open access)

Advanced Hydrogen Transport Membranes for Vision 21 Fossil Fuel Plants

The objective of this project is to develop an environmentally benign, inexpensive, and efficient method for separating hydrogen from gas mixtures produced during industrial processes, such as coal gasification. Currently, this project is focusing on four basic categories of dense membranes: (1) mixed conducting ceramic/ceramic composites, (2) mixed conducting ceramic/metal (cermet) composites, (3) cermets with hydrogen permeable metals, and (4) layered composites with hydrogen permeable alloys. The primary technical challenge in achieving the goals of this project will be to optimize membrane composition to enable practical hydrogen separation rates and chemical stability. Other key aspects of this developing technology include catalysis, ceramic processing methods, and separation unit design operating under high pressure. To achieve these technical goals, Eltron Research Inc. has organized a consortium consisting of CoorsTek, Sued Chemie, Inc. (SCI), Argonne National Laboratory (ANL), and NORAM. Hydrogen permeation rates in excess of 50 mL {center_dot} min{sup -1} {center_dot} cm{sup 2} at {approx}440 C were routinely achieved under less than optimal experimental conditions using a range of membrane compositions. Factors that limit the maximum permeation attainable were determined to be mass transport resistance of H{sub 2} to and from the membrane surface, as well as surface contamination. Mass transport resistance …

An Analysis of Price Determination and Markups in the Air-Conditioning and Heating Equipment Industry (open access)

An Analysis of Price Determination and Markups in the Air-Conditioning and Heating Equipment Industry

In this report we calculate the change in final consumer prices due to minimum efficiency standards, focusing on a standard economic model of the air-conditioning and heating equipment (ACHE) wholesale industry. The model examines the relationship between the marginal cost to distribute and sell equipment and the final consumer price in this industry. The model predicts that the impact of a standard on the final consumer price is conditioned by its impact on marginal distribution costs. For example, if a standard raises the marginal cost to distribute and sell equipment a small amount, the model predicts that the standard will raise the final consumer price a small amount as well. Statistical analysis suggest that standards do not increase the amount of labor needed to distribute equipment the same employees needed to sell lower efficiency equipment can sell high efficiency equipment. Labor is a large component of the total marginal cost to distribute and sell air-conditioning and heating equipment. We infer from this that standards have a relatively small impact on ACHE marginal distribution and sale costs. Thus, our model predicts that a standard will have a relatively small impact on final ACHE consumer prices. Our statistical analysis of U.S. Census …

Calcium Carbonate Production by Coccolithaphorid Algae in Long Term, Carbon Dioxide Sequestration (open access)

Calcium Carbonate Production by Coccolithaphorid Algae in Long Term, Carbon Dioxide Sequestration

Predictions of increasing levels of anthropogenic carbon dioxide (CO{sub 2}) and the specter of global warming have intensified research efforts to identify ways to sequester carbon. A number of novel avenues of research are being considered, including bioprocessing methods to promote and accelerate biosequestration of CO{sub 2} from the environment through the growth of organisms such as coccolithophorids, which are capable of sequestering CO{sub 2} relatively permanently. Calcium and magnesium carbonates are currently the only proven, long-term storage reservoirs for carbon. Whereas organic carbon is readily oxidized and releases CO{sub 2} through microbial decomposition on land and in the sea, carbonates can sequester carbon over geologic time scales. This proposal investigates the use of coccolithophorids--single-celled, marine algae that are the major global producers of calcium carbonate--to sequester CO{sub 2} emissions from power plants. Cultivation of coccolithophorids for calcium carbonate (CaCO{sub 3}) precipitation is environmentally benign and results in a stable product with potential commercial value. Because this method of carbon sequestration does not impact natural ecosystem dynamics, it avoids controversial issues of public acceptability and legality associated with other options such as direct injection of CO{sub 2} into the sea and ocean fertilization. Consequently, cultivation of coccolithophorids could be carried …

Centers for Disease Control and Prevention: Agency Leadership Taking Steps to Improve Management and Planning, but Challenges Remain (open access)

Centers for Disease Control and Prevention: Agency Leadership Taking Steps to Improve Management and Planning, but Challenges Remain

A letter report issued by the General Accounting Office with an abstract that begins "The scope of work at the Centers for Disease Control and Prevention (CDC) has evolved since 1946 from a focus on communicable diseases, like malaria, to a wide and complex range of public health responsibilities. The agency's Office of the Director (OD) faces considerable management challenges to ensure that during public health crises the agency's nonemergency but important public health work continues apace. In 2002, the agency's OD began taking steps aimed at organizational change. GAO has observed elsewhere that major change management initiatives can take at least 5 to 7 years. In this report, GAO examined the extent to which organizational changes have helped balance OD's oversight of CDC's emergent and ongoing public health responsibilities. Specifically, GAO examined OD's (1) executive management structure, (2) approach to overseeing the agency's work, and (3) approach to setting the agency's priorities."

Climate Change: Analysis of Two Studies of Estimated Costs of Implementing the Kyoto Protocol (open access)

Climate Change: Analysis of Two Studies of Estimated Costs of Implementing the Kyoto Protocol

Correspondence issued by the General Accounting Office with an abstract that begins "In 1992 the United States ratified the United Nations Framework Convention on Climate Change, which was intended to stabilize the buildup of greenhouse gases in the earth's atmosphere but did not impose binding limits on emissions. In July 1997, when preliminary negotiations on a new climate agreement were under way, the Senate passed a resolution expressing the sense of the Senate that the Clinton administration should not agree to limits on U.S. greenhouse gas emissions if such an agreement did not include economically developing nations or if it could seriously harm the U.S. economy. In December 1997 the United States participated in drafting the Kyoto Protocol, an international agreement to specifically limit greenhouse gas emissions. The Protocol did not impose limits on developing nations' emissions, and its possible effect on the U.S. economy was the subject of numerous studies during that period, including the two studies that are the subject of this report. Although the U.S. government signed the Protocol in 1998, the Clinton administration did not submit it to the Senate for advice and consent, which are necessary for ratification. In March 2001, President Bush announced that …

Competitive sorption of cadmium and lead in acid soils of central Spain (open access)

Competitive sorption of cadmium and lead in acid soils of central Spain

The bioavailability and ultimate fate of heavy metals in the environment are controlled by chemical sorption. To assess competitive sorption of Pb and Cd, batch equilibrium experiments (generating sorption isotherms) and kinetics sorption studies were performed using single and binary metal solutions in surface samples of four soils from central Spain. For comparisons between soils, as well as, single and binary metal solutions, soil chemical processes were characterized using the Langmuir equation, ionic strength, and an empirical power function for kinetic sorption. In addition, soil pH and clay mineralogy were used to explain observed sorption processes. Sorption isotherms were well described by the Langmuir equation and the sorption kinetics were well described by an empirical power function within the reaction times in this study. Soils with higher pH and clay content (characterized by having smectite) had the greatest sorption capacity as estimated by the maximum sorption parameter (Q) of the Langmuir equation. All soils exhibited greater sorption capacity for Pb than Cd and the presence of both metals reduced the tendency for either to be sorbed although Cd sorption was affected to a greater extent than that of Pb. The Langmuir binding strength parameter (k) was always greater for Pb …

Consumer Protection: Federal and State Agencies Face Challenges in Combating Predatory Lending

A chapter report issued by the General Accounting Office with an abstract that begins "While there is no universally accepted definition, the term "predatory lending" is used to characterize a range of practices, including deception, fraud, or manipulation, that a mortgage broker or lender may use to make a loan with terms that are disadvantageous to the borrower. No comprehensive data are available on the extent of these practices, but they appear most likely to occur among subprime mortgages--those made to borrowers with impaired credit or limited incomes. GAO was asked to examine actions taken by federal agencies and states to combat predatory lending; the roles played by the secondary market and by consumer education, mortgage counseling, and loan disclosure requirements; and the impact of predatory lending on the elderly."

The Department of Homeland Security Needs to Fully Adopt a Knowledge-based Approach to Its Counter-MANPADS Development Program

Correspondence issued by the General Accounting Office with an abstract that begins "In late 2002, terrorists fired surface-to-air missiles at an Israeli airliner departing from Mombasa, Kenya--the first time man-portable air defense systems (MANPADS) had been used to attack commercial aircraft in a non-combat zone. Given concerns about the vulnerability of the commercial airline industry and the potential impact of an attack in the United States, the House Committee on Armed Services and the House Committee on Transportation and Infrastructure, Aviation Subcommittee, requested that we conduct an assessment of the federal government's efforts to address the MANPADS threat against commercial aircraft, including its nature and extent; the Department of Defense's monitoring of Stinger missiles exported to other countries; and U.S. bilateral and multilateral efforts to address international MANPADS proliferation. After we began work on this assessment, the Department of Homeland Security (DHS) took steps to initiate a 2-year system development and demonstration program for a counter-MANPADS system and awarded the initial contracts in January 2004. On December 4, 2003, we briefed Congress on our views about DHS's approach to developing the system. This report summarizes that information and transmits the portion of the briefing related to DHS's counter-MANPADS development effort. …

THE DEVELOPMENT OF COAL-BASED TECHNOLOGIES FOR DEPARTMENT OF DEFENSE FACILITIES (open access)

THE DEVELOPMENT OF COAL-BASED TECHNOLOGIES FOR DEPARTMENT OF DEFENSE FACILITIES

The third phase of a three-phase project investigating the development of coal-based technologies for US Department of Defense (DOD) facilities was completed. The objectives of the project were to: decrease DOD's dependence on foreign oil and increase its use of coal; promote public and private sector deployment of technologies for utilizing coal-based fuels in oil-designed combustion equipment; and provide a continuing environment for research and development of coal-based fuel technologies for small-scale applications at a time when market conditions in the US are not favorable for the introduction of coal-fired equipment in the commercial and industrial capacity ranges. The Phase III activities were focused on evaluating deeply-cleaned coals as fuels for industrial boilers and investigating emissions control strategies for providing ultra-low emissions when firing coal-based fuels. This was addressed by performing coal beneficiation and preparation studies, and bench- to demonstration-scale emissions reduction studies. In addition, economic studies were conducted focused on determining cost and market penetration, selection of incentives, and regional economic impacts of coal-based technologies.

Direct evidence of the fermi-energy-dependent formation of Mn interstitials in modulation doped Ga1-yAlyAs/Ga1-xMnxAs/Ga1-yAlyAs heterostructures (open access)

Direct evidence of the fermi-energy-dependent formation of Mn interstitials in modulation doped Ga1-yAlyAs/Ga1-xMnxAs/Ga1-yAlyAs heterostructures

Using ion channeling techniques, we investigate the lattice locations of Mn in Ga{sub 1-x}Mn{sub x}As quantum wells between Be-doped Ga{sub 1-y}Al{sub y}As barriers. The earlier results showed that the Curie temperature T{sub C} depends on the growth sequence of the epitaxial layers. A lower T{sub C} was found in heterostructures in which the Ga{sub 1-x}Mn{sub x}As layer is grown after the modulation-doped barrier. Here we provide direct evidence that this reduction in T{sub C} is directly correlated with an increased formation of magnetically inactive Mn interstitials. The formation of interstitials is induced by a shift of the Fermi energy as a result of the transfer of holes from the barrier to the quantum well during the growth.

DropTests of 325 Pound 6M Packages (open access)

DropTests of 325 Pound 6M Packages

There are many factors which affect the performance of a drum closure during drop tests. Important test conditions are: weight of package, height of drop, and angle of impact. Structural characteristics of the package determine its ability to withstand the test conditions imposed. These characteristics include: package diameter, shell material and thickness, strength of internal fill material (e.g., fiberboard), and configuration of closure (clamp-ring, bolted flange, etc.). For the clamp-ring closure configuration a study of published drop test results has shown that packages having a weight ratio of less than 50 per cent were typically able to retain their lids in hypothetical accident condition, 30-ft drop tests. Those having weight ratios greater than 50 per cent typically failed. Prior testing over the integrity of the clamp-ring closure, consistently demonstrated that the clamp-ring is unable to retain the drum lid in thirty foot drop tests of packages containing the maximum allowed weight (640 lb), which confirms the previous studies. To determine if the clamp-ring closure is adequate for packages with lower weight contents, a series of tests were performed on packages weighing around 325 lb (i.e., a typical shipping weight for DOE packages) at a range of impact angles as detailed …

ENHANCED PRACTICAL PHOTOSYNTHETIC CO2 MITIGATION

This quarterly report documents significant achievements in the Enhanced Practical Photosynthetic CO{sub 2} Mitigation project during the period from 10/2/2003 through 1/1/2004. As indicated in the list of accomplishments below we have seen very encouraging results from the model scale tests in terms of organism growth rates and we have begun the final tests necessary to meet our project goals. Specific results and accomplishments for the fourth quarter of 2003 include: (1) Bioreactor support systems and test facilities--(A) The solar collector is working well and has survived the winter weather. (B) The improved high-flow CRF-2 test system has been used successfully to run several long-term growth tests with periodic harvesting events. The high flow harvesting system performed well. The mass measurement results after a 4-week test show 275% growth over the initial mass loading. This figure would have been higher had there been no leakage and handling losses. Carbon dating of biomass from this test is planned for carbon uptake estimation. The next test will include direct measurement of carbon uptake in addition to organism mass measurements. (C) Qualitative organism growth testing has begun in the pilot scale bioreactor. Some issues with uniformity of organism loading, fluid leakage and evaporation …
