Health Resources and Services Administration: Many Underserved Areas Lack a Health Center Site, and Data Are Needed on Service Provision at Sites
Testimony issued by the Government Accountability Office with an abstract that begins "Health centers funded through grants under the Health Center Program--managed by the Health Resources and Services Administration (HRSA) of the U.S. Department of Health and Human Services (HHS)--provide comprehensive primary care services for the medically underserved. The statement GAO is issuing today summarizes an August 2008 report, Health Resources and Services Administration: Many Underserved Areas Lack a Health Center Site, and the Health Center Program Needs More Oversight (GAO-08-723). In that report, GAO examined to what extent medically underserved areas (MUA) lacked health center sites in 2006 and 2007. To do this, GAO obtained and analyzed HRSA data and grant application"

Higher Education: Approaches to Attract and Fund International Students in the United States and Abroad
A letter report issued by the Government Accountability Office with an abstract that begins "Following September 11, 2001, the number of international students coming to the United States dropped for the first time in over 30 years. While enrollments have rebounded, the U.S. image has declined in the Muslim world and elsewhere. To improve global attitudes toward America, the U.S. government funds higher education for international students to facilitate exchanges, promote understanding among peoples in different countries, and build capacity in developing nations. To provide insight on how higher education is used to advance public diplomacy and development assistance goals, we examined (1) the objectives the United States and selected peer governments seek to advance through higher education for international students and the approaches they employ to attract international students, and (2) the characteristics of major U.S. and peer government programs that fund higher education for international students to support public diplomacy and development goals. GAO collected information from the United States, Australia, China, the European Commission, Germany, and the United Kingdom."

Hospital Emergency Departments: Bibliography (GAO-09-348SP, April 30, 2009), an E-supplement to GAO-09-347
Other written product issued by the Government Accountability Office with an abstract that begins "This is an e-supplement to GAO-09-347. This document presents a bibliography of a literature review conducted as part of our work on emergency department crowding (GAO-09-347). As part of our work to analyze and report on information made available since 2003 about (1) three indicators of emergency department crowding--ambulance diversion, wait times, and patient boarding, and (2) factors that contribute to emergency department crowding, we conducted a literature review of 197 articles, including articles published in peer-reviewed and other periodicals, publications from professional, research, and other organizations, and reports issued by federal and state agencies. In examining the information made available since 2003 about indicators of crowding during our literature review, we also analyzed articles for what was reported on the effect of crowding on patient quality of care and proposed strategies to address crowding. In order to obtain these articles, we conducted structured searches of 16 research databases and obtained articles identified as a result of interviews with federal officials, professional and research organizations, and subject-matter experts, and through searches of related Web sites. We reviewed 197 articles, publications, and reports (which we call articles) …

Hospital Emergency Departments: Crowding Continues to Occur, and Some Patients Wait Longer than Recommended Time Frames
A letter report issued by the Government Accountability Office with an abstract that begins "Hospital emergency departments are a major part of the nation's health care safety net. Of the estimated 119 million visits to U.S. emergency departments in 2006, over 40 percent were paid for by federally-supported programs. These programs--Medicare, Medicaid, and the State Children's Health Insurance Program--are administered by the Department of Health and Human Services (HHS). There have been reports of crowded conditions in emergency departments, often associated with adverse effects on patient quality of care. In 2003, GAO reported that most emergency departments in metropolitan areas experienced some degree of crowding (Hospital Emergency Departments: Crowded Conditions Vary among Hospitals and Communities, GAO-03-460). For example, two out of every three metropolitan hospitals reported going on ambulance diversion--asking ambulances to bypass their emergency departments and instead transport patients to other facilities. GAO was asked to examine information made available since 2003 on emergency department crowding. GAO examined three indicators of emergency department crowding--ambulance diversion, wait times, and patient boarding--and factors that contribute to crowding. To conduct this work, GAO reviewed national data; conducted a literature review of 197 articles; and interviewed officials from HHS and professional and research …

Laser Timing Jitter Measurements using a Dual-Sweep Streak Camera at the A0 Photoinjector
Excellent phase stability of the drive laser is a critical performance specification of photoinjectors such as Fermilab's A0 photoinjector (A0PI). Previous efforts based on the measurement of the power spectrum of the signal of a fast photodiode illuminated by the mode locked infrared laser pulse component indicated a phase jitter of less than 1.4 ps (technique limited). A recently procured dual sweep plugin unit and existing Hamamatsu C5680 streak camera were used to study the phase stability of the UV laser pulse component. Initial measurements with the synchroscan vertical sweep unit locked to 81.25 MHz showed that the phase slew through the micropulse train and the phase jitter micropulse to micropulse were two key aspects that could be evaluated. The phase slew was much less than 100 fs per micropulse, and the total phase jitter (camera, trigger, and laser) was approximately 300 fs RMS for measurements of 50-micropulse trains. Data on the macropulse phase stability were also obtained. A possible upgrade to achieve better phase stability will be also discussed.

Linear pi-Acceptor-Templated Dynamic Clipping to Macrobicycles and[2]Rotaxanes
Functional rotaxanes are one of the representative nanoscale molecular machines that have found applications in many areas, including molecular electronics, nanoelectromechanical systems (NEMS), photo controllable smart surfaces, and nanovalves. With the advent of molecular recognition and self-assembly, such molecular compounds can now be obtained efficiently through template-directed synthesis. One of the common strategies of making [2]rotaxanes involves the clipping of a macrocycle around a preformed dumbbell-shaped template in a [1+1] or [2+2] manner. While early examples were based on irreversible kinetic pathway through covalent bond formation, recent advances on reversible dynamic covalent chemistry (DCC) has attracted great attention to this field. By virtue of thermodynamically controlled equilibria, DCC has provided highly efficient and versatile synthetic routes in the selection of specific products from a complex system. Among the several reversible reactions in the category of DCC reactions, the imine formation has proven to be very versatile in macrocyclization to give complex interlocked molecular compounds. Cryptands are three dimensional bicyclic hosts with preorganized cavities capable of inclusion of ions and small molecules. Replacing the nitrogen bridgeheads in common cryptands with aromatic ring systems gives cyclophane-based macrobicycles. The introduction of aromatic ring systems into a preorganized cage-like geometry facilitates ion-{pi} interactions and …

Long-Term Carbon Injection Field Test for 90% Mercury Removal for a PRB Unit a Spray Dryer and Fabric Filter: Final Scientific/Technical Report
The power industry in the U.S. is faced with meeting regulations to reduce the emissions of mercury compounds from coal-fired plants. Injecting a sorbent such as powdered activated carbon (PAC) into the flue gas represents one of the simplest and most mature approaches to controlling mercury emissions from coal-fired boilers. The purpose of this test program was to evaluate the long-term mercury removal capability, long-term mercury emissions variability, and operating and maintenance (O&M) costs associated with sorbent injection on a configuration being considered for many new plants. Testing was conducted by ADA Environmental Solutions (ADA) at Rocky Mountain Power’s (RMP) Hardin Station through funding provided by DOE/NETL, RMP, and other industry partners. The Hardin Station is a new plant rated at 121 MW gross that was first brought online in April of 2006. Hardin fires a Powder River Basin (PRB) coal and is configured with selective catalytic reduction (SCR) for NOx control, a spray dryer absorber (SDA) for SO2 control, and a fabric filter (FF) for particulate control. Based upon previous testing at PRB sites with SCRs, very little additional mercury oxidation from the SCR was expected at Hardin. In addition, based upon results from DOE/NETL Phase II Round I …

National Preparedness: FEMA Has Made Progress, but Needs to Complete and Integrate Planning, Exercise, and Assessment Efforts
A letter report issued by the Government Accountability Office with an abstract that begins "Hurricane Katrina was the most destructive disaster in our nation's history and it highlighted gaps in preparedness for a catastrophic disaster. The Federal Emergency Management Agency (FEMA), a component within the Department of Homeland Security (DHS), is the lead federal agency responsible for developing a national preparedness system. The system includes policies and plans as well as exercises and assessments of capabilities across many public and private entities. GAO was asked to assess the extent to which FEMA has (1) developed policies and plans that define roles and responsibilities; (2) implemented the National Exercise Program, a key tool for examining preparedness; (3) developed a national capabilities assessment; and (4) developed a strategic plan that integrates these elements of the preparedness system. GAO analyzed program documents, such as after-action reports, and visited six states located in disaster regions. While the results of these visits are not generalizable, they show how select states carry out their efforts."

The Nation's Long-Term Fiscal Outlook: March 2009 Update
Other written product issued by the Government Accountability Office with an abstract that begins "The new President, the new Congress, and the American people have been understandably focused on addressing problems with financial markets and responding to the economic downturn. However, the nation will need to apply the same level of intensity to the nation's long-term fiscal challenge. As shown in the figure below and the attached charts, GAO's updated simulations continue to show escalating and persistent debt that illustrates the long-term fiscal outlook is unsustainable. By 2025, debt held by the public under the Alternative simulation exceeds the historical high reached in the aftermath of World War II."

Neutron Energy Measurements in Radiological Emergency Response Applications
We present significant results in recent advances in the determination of neutron energy. Neutron energy measurements are a small but very significant part of radiological emergency response applications. Mission critical information can be obtained by analyzing the neutron energy given off from radioactive materials. In the case of searching for special nuclear materials, neutron energy information from an unknown source can be of paramount importance.

New Markets Tax Credit: Minority Entities Are Less Successful in Obtaining Awards Than Non-Minority Entitities
A letter report issued by the Government Accountability Office with an abstract that begins "The Community Development Financial Institutions (CDFI) Fund in the Department of the Treasury has awarded $19.5 billion of the $26 billion in New Markets Tax Credits (NMTC) it is authorized to award through 2009 to encourage investment in low-income communities. The NMTC allows investors to claim a tax credit in exchange for investing in Community Development Entities (CDE) that reinvest the funds in qualified communities. Recent congressional interest has focused on participation by minority CDEs. As requested, this report (1) identifies the number of minority and non-minority CDEs that have applied to the CDFI Fund and received NMTC awards, (2) explains the process by which the CDFI Fund makes NMTC awards and summarizes application scores, (3) describes challenges, if any, minority and non-minority CDEs face in applying for and receiving NMTC awards and (4) identifies efforts the CDFI Fund and others are taking to assist minority CDEs in applying for NMTC awards. GAO analyzed CDFI Fund application data and interviewed minority and non-minority CDE officials, the CDFI Fund, and industry groups."

Novel Dual-Functional Membrane for Controlling Carbon Dioxide Emissions from Fossil Fuel Power Plants
CO{sub 2} captured from coal-fired power plants represents three-quarters of the total cost of an entire carbon sequestration process. Conventional amine absorption or cryogenic separation requires high capital investment and is very energy intensive. Our novel membrane process is energy efficient with great potential for economical CO{sub 2} capture. Three classes of microporous sol-gel derived silica-based membranes were developed for selective CO{sub 2} removal under simulated flue gas conditions (SFG), e.g. feed of 10% vol. CO{sub 22} in N{sub 2}, 1 atm total pressure, T = 50-60 C, RH>50%, SO2>10 ppm. A novel class of amine-functional microporous silica membranes was prepared using an amine-derivatized alkoxysilane precursor, exhibiting enhanced (>70) CO{sub 2}:N{sub 2} selectivity in the presence of H{sub 2}O vapor, but its CO{sub 2} permeance was lagging (<1 MPU). Pure siliceous membranes showed higher CO{sub 2} permeance (1.5-2 MPU) but subsequent densification occurred under prolonged SFG conditions. We incorporated NiO in the microporous network up to a loading of Ni:Si = 0.2 to retard densification and achieved CO2 permeance of 0.5 MPU and CO{sub 2}:N{sub 2} selectivity of 50 after 163 h exposure to SFG conditions. However, CO{sub 2} permeance should reach greater than 2.0 MPU in order to achieve …
