Isotope applications in the environmental field (open access)

Isotope applications in the environmental field

Established uses of enriched isotopes in the environmental field were surveyed to determine future trends in isotope needs. Based on established isotope uses, on the projected increase in the pollution problem, and on the apparent social and economic pressure for pollution abatement, a significant demand for enriched isotopes appears to be developing for the assessment and control of air, water, and soil pollutants. Isotopic techniques will be used in combination with conventional methods of detection and measurement, such as gas chromatography, x-ray fluorescence, and atomic absorption. Recent advances in economical isotope separation methods, instrumentation, and methodology promise to place isotopic technology within the reach of most research and industrial institutions. Increased application of isotope techniques appears most likely to occur in areas where data are needed to characterize the movement, behavior, and fate of pollutants in the environment.

Electronic Waste: Actions Needed to Provide Assurance That Used Federal Electronics Are Disposed of in an Environmentally Responsible Manner

A letter report issued by the Government Accountability Office with an abstract that begins "Over the past decade, the executive branch has taken steps to improve the management of used federal electronics. Notably, in 2003, EPA helped to pilot the Federal Electronics Challenge (FEC)—a voluntary partnership program that encourages federal facilities and agencies to purchase environmentally friendly electronic products, reduce the impacts of these products during their use, and manage used electronics in an environmentally safe way. EPA also led an effort and provided initial funding to develop third-party certification so that electronics recyclers could show that they are voluntarily adhering to an adopted set of best practices for environmental protection, worker health and safety, and security practices. In 2006, GSA issued its Personal Property Disposal Guide to assist agencies in understanding the hierarchy for disposing of excess personal property, including used electronic products: reutilization, donation, sale, and abandonment or destruction. In 2007 and 2009, executive orders were issued that, among other things, established improvement goals and directed agencies to develop and implement improvement plans for the management of used electronics. The Office of Management and Budget, the Council on Environmental Quality, and the Office of the Federal Environmental Executive …

Electronic Personal Health Information Exchange: Health Care Entities' Reported Disclosure Practices and Effects on Quality of Care (open access)

Electronic Personal Health Information Exchange: Health Care Entities' Reported Disclosure Practices and Effects on Quality of Care

A letter report issued by the Government Accountability Office with an abstract that begins "To promote the use of information technology for the electronic exchange of personal health information among providers and other health care entities, Congress passed the Health Information Technology for Economic and Clinical Health (HITECH) Act. It provides incentives intended to promote the widespread adoption of technology that supports the electronic sharing of data among hospitals, physicians, and other health care entities. Pursuant to a requirement in the HITECH Act, GAO is reporting on practices implemented by health information exchange organizations, providers, and other health care entities that disclose electronic personal health information. GAO's specific objectives were to describe (1) the practices implemented for disclosing personal health information for purposes of treatment, including the use of electronic means for obtaining consent, as reported by selected health information exchange organizations, their participating providers, and other entities; and (2) the effects of the electronic sharing of health information on the quality of care for patients as reported by these organizations. To address both objectives, GAO conducted case studies of 4 of more than 60 operational health information exchanges and a selection of each of the exchanges' participating providers."

Information Technology: Departments of Defense and Energy Need to Address Potentially Duplicative Investments

A letter report issued by the Government Accountability Office with an abstract that begins "Although the Departments of Defense (DOD) and Energy (DOE) use various investment review processes to identify duplicative investments, GAO found that 37 of its sample of 810 investments were potentially duplicative. These investments account for about $1.2 billion in total information technology (IT) spending for fiscal years 2007 through 2012. For example, GAO identified four DOD Navy personnel assignment investments—one system for officers, one for enlisted personnel, one for reservists, and a general assignment system—each of which is responsible for managing similar functions. While GAO did not identify any potentially duplicative investments at the Department of Homeland Security (DHS) within its sample, DHS officials have independently identified several duplicative investments and systems."

Electronic Prescribing: CMS Should Address Inconsistencies in Its Two Incentive Programs That Encourage the Use of Health Information Technology (open access)

Electronic Prescribing: CMS Should Address Inconsistencies in Its Two Incentive Programs That Encourage the Use of Health Information Technology

A letter report issued by the Government Accountability Office with an abstract that begins "Congress established two CMS-administered programs--the Electronic Prescribing Program and the Electronic Health Records (EHR) Program--that provide incentive payments to eligible Medicare providers who adopt and use health information technology, and penalties for those who do not. The Medicare Improvements for Patients and Providers Act of 2008 required GAO to report on the Electronic Prescribing Program. To do so, GAO examined how CMS determines which providers receive incentive payments and avoid penalties from that program and how many providers received incentive payments in 2009. Also, GAO was asked to examine how the requirements of the two programs compare. GAO reviewed relevant laws and regulations, interviewed CMS officials, and analyzed CMS data on incentive payments made for 2009, which were the most recent data available for a full year."

Measuring Performance: The Corporation for National and Community Service Faces Challenges Demonstrating Outcomes

A letter report issued by the Government Accountability Office with an abstract that begins "CNCS officials expect that most grantees from its main programs will adopt at least 1 of the agency’s 16 agency-wide performance measures. Specifically, officials told us that AmeriCorps State and National and VISTA grantees will adopt at least 1 of CNCS’s performance measures by fiscal year 2012, and Senior Corps grantees will adopt at least 1 measure by fiscal year 2013. However, officials also said that they plan to fund some activities that do not fall under the performance measures, particularly activities that meet local needs and/or are innovative. For example, CNCS has funded grantees in the state of Washington to carry out gang violence prevention activities to address this community challenge. This could present challenges for CNCS as it balances accountability, using its performance measures to assess the impact of grantees’ service activities, with flexibility, allowing grantees to take on projects that meet local needs. CNCS may find it difficult to demonstrate the effectiveness of its service activities that fall outside its performance measures. Additionally, CNCS faces challenges using its performance measures to promote accountability among its Senior Corps grantees, as legal restrictions make it …

Physics design of a cold neutron source for KIPT neutron source facility. (open access)

Physics design of a cold neutron source for KIPT neutron source facility.

Argonne National Laboratory (ANL) of USA and Kharkov Institute of Physics and Technology (KIPT) of Ukraine have been collaborating on the conceptual design development of a neutron source facility. It is based on the use of an electron accelerator driven subcritical (ADS) facility with low enriched uranium fuel, using the existing electron accelerators at KIPT of Ukraine [1]. The neutron source of the subcritical assembly is generated from the interaction of 100-KW electron beam, which has a uniform spatial distribution and the electron energy in the range of 100 to 200 MeV, with a natural uranium target [2]. The main functions of the facility are the production of medical isotopes and the support of the Ukraine nuclear power industry. Neutron beam experiments and material studies are also included. Over the past two-three decades, structures with characteristic lengths of 100 {angstrom} and correspondingly smaller vibrational energies have become increasingly important for both science and technology [3]. The characteristic dimensions of the microstructures can be well matched by neutrons with longer vibrational wavelength and lower energy. In the accelerator-driven subcritical facility, most of the neutrons are generated from fission reactions with energy in the MeV range. They are slowed down to the …

High Efficiency Solar Power via Separated Photo and Voltaic Pathways (open access)

High Efficiency Solar Power via Separated Photo and Voltaic Pathways

This project demonstrates a novel nanostructured solar cell architecture capable of achieving high efficiency levels that is relatively simple and inexpensive to manufacture. The high efficiency will be achieved by the novel structure that separates the path of the photons from the path of the generated charge carriers. In this way, the photon path can be long for maximum light absorption, while the path for carriers can be short for maximum electronic energy harvesting. The combination of maximum light absorption coupled with maximum carrier harvesting is the basis for the expected high efficiency. The project will develop high efficiency solar cell prototypes utilizing this unique nanostructured architecture. The project addresses the fundamental limitation inherent in all current solar cell designs, and which opens a pathway to development for high efficiency solar cells at low cost. Realizing this goal will result in a levelized cost of electricity in the range of 10¢/kWh, which would achieve the long-sought goal of making photovoltaic electricity cost competitive with fossil-fuel generated electricity without any governmental subsidies. This breakthrough would spur the already rapid growth in the photovoltaic industry to an explosive pace, with significant, widespread benefit to the national economy and the nation’s energy security. …
