Resource use efficiency of closed plant production system with artificial light: Concept, estimation and application to plant factory

PubMed Central

KOZAI, Toyoki

2013-01-01

Extensive research has recently been conducted on plant factory with artificial light, which is one type of closed plant production system (CPPS) consisting of a thermally insulated and airtight structure, a multi-tier system with lighting devices, air conditioners and fans, a CO2 supply unit, a nutrient solution supply unit, and an environment control unit. One of the research outcomes is the concept of resource use efficiency (RUE) of CPPS. This paper reviews the characteristics of the CPPS compared with those of the greenhouse, mainly from the viewpoint of RUE, which is defined as the ratio of the amount of the resource fixed or held in plants to the amount of the resource supplied to the CPPS. It is shown that the use efficiencies of water, CO2 and light energy are considerably higher in the CPPS than those in the greenhouse. On the other hand, there is much more room for improving the light and electric energy use efficiencies of CPPS. Challenging issues for CPPS and RUE are also discussed. PMID:24334509

During the 2 1/2 days of the workshop, a number of issues relating to obtaining frequency-stable operation and to the catalytic control of laser gas chemistry were discussed, and specific recommendations concerning future activities were drafted.

The early history of the closed loop fiber optic gyro and derivative sensors at McDonnell Douglas, Blue Road Research and Columbia Gorge Research

NASA Astrophysics Data System (ADS)

Udd, Eric

2016-05-01

On September 29, 1977 the first written disclosure of a closed loop fiber optic gyro was witnessed and signed off by four people at McDonnell Douglas Astronautics Company in Huntington Beach, California. Over the next ten years a breadboard demonstration unit, and several prototypes were built. In 1987 the fundamental patent for closed loop operation began a McDonnell Douglas worldwide licensing process. Internal fiber optic efforts were redirected to derivative sensors and inventions. This included development of acoustic, strain and distributed sensors as well as a Sagnac interferometer based secure fiber optic communication system and the new field of fiber optic smart structures. This paper provides an overview of these activities and transitions.

Top management and management science: An exploratory study in 15 Federal civilian agencies

White, M. J.

1971-01-01

A study of the relation between top managers in Federal agencies and the operations research and management science (OR/MS) group is reported. Sixteen managers were questioned about the following characteristics: closeness of top managers to OR/MS groups; top managers' attitudes toward the OR/MS activities; relation between closeness and these attitudes; and top managers' use of OR/MS groups. It is concluded that OR/MS is relevant to many top managers and that OR/MS has begun to play a role in decisions. Top management attitudes and actions are not related in obvious ways. The consequences to top management's use of and closeness to an OR/MS group need not be the success of the group as a professional, innovative, research-oriented unit.

Studies on maximum yield of wheat for the controlled environments of space

NASA Technical Reports Server (NTRS)

Bugbee, B. G.; Salisbury, F. B.

1986-01-01

The economic feasibility of using food-producing crop plants in a closed ecological Life-Support System (CELSS) will ultimately depend on the energy and area (or volume) required to provide the nutritional requirements for each person. Energy and area requirements are, to some extent, inversely related; that is, an increased energy input results in a decreased area requirement and vice versa. A major goal of the research effort was to determine the controlled-environment good-production efficiency of wheat per unit area, per unit time, and per unit energy input.

Effect of accuracy of wind power prediction on power system operator

NASA Technical Reports Server (NTRS)

Schlueter, R. A.; Sigari, G.; Costi, T.

1985-01-01

This research project proposed a modified unit commitment that schedules connection and disconnection of generating units in response to load. A modified generation control is also proposed that controls steam units under automatic generation control, fast responding diesels, gas turbines and hydro units under a feedforward control, and wind turbine array output under a closed loop array control. This modified generation control and unit commitment require prediction of trend wind power variation one hour ahead and the prediction of error in this trend wind power prediction one half hour ahead. An improved meter for predicting trend wind speed variation is developed. Methods for accurately simulating the wind array power from a limited number of wind speed prediction records was developed. Finally, two methods for predicting the error in the trend wind power prediction were developed. This research provides a foundation for testing and evaluating the modified unit commitment and generation control that was developed to maintain operating reliability at a greatly reduced overall production cost for utilities with wind generation capacity.

Davis, J. E.

1972-01-01

The Brayton rotating unit (BRU), operating on a gas bearing system, has been designed, fabricated, and demonstrated for use in a closed Brayton cycle space power conversion system. The BRU uses a binary mixture of xenon and helium (molecular weight, 83.8) as the cycle working fluid and bearing lubricating medium and was designed to produce from 2.25 to 10.5 kw sub e of 1200 Hz three-phase electrical power. The single-shaft rotating assembly operates at a design speed of 36,000 rpm and comprises a radial single-stage compressor, a four-pole Rice alternator rotor, and a radial inflow turbine. Four units, a dynamic simulator and three component research packages, were supplied to the NASA Lewis Research Center for performance testing and further development.

[The Clinical Investigation Centers in France: Whatzat? What for? How does it work?].

PubMed

Montagne, O; Le Corvoisier, P

2008-01-01

For the last 15 years, French university-affiliated hospitals have dramatically modified how biomedical research is conducted in France. Multidisciplinary and technically complex research projects are increasingly difficult to conduct in clinical units. To ensure quality, good clinical practice, and security, platforms dedicated to clinical research with specific staff have been implanted. These units, called Clinical Investigation Centers (CICs), are open to academic and industrial investigators working in the medical fields involving patients and healthy volunteers. The CICs' activities are always closely related to the university hospital research programs and can also serve as a tool for locally implanted clinical and fundamental research teams (INSERM). Nowadays, clinical research requires specific tools and platforms. To enhance French university hospital research efficiency and provide a more open research environment, all investigators, on-site as well as from other institutions, are invited to use these cohesive research facilities and skills to conduct protocols that are fully adapted to their needs in optimal conditions of professional clinical research.

2011-03-01

To describe a framework to assist pediatric intensive care unit physicians in conducting follow-up meetings with parents after their child's death. Many childhood deaths occur in pediatric intensive care units. Parents of children who die in pediatric intensive care units often desire a follow-up meeting with the physician(s) who cared for their child. Prior research conducted by the Collaborative Pediatric Critical Care Research Network on the experiences and perspectives of bereaved parents and pediatric intensive care unit physicians regarding the desirability, content, and conditions of follow-up meetings. The framework includes suggestions for inviting families to follow-up meetings (i.e., developing an institutional system, invitation timing, and format); preparing for the meeting (i.e., assessing family preferences; determining location, attendees, and discussion topics; reviewing medical and psychosocial history); structure of the meeting (i.e., opening, closing, and developing a meeting agenda); communicating effectively during the meeting; and follow-up for both parents and physicians. This framework is based on the experience and perspectives of bereaved parents and pediatric intensive care unit physicians. Future research should be conducted to determine the extent to which physician-parent follow-up meetings provide a benefit to parents, families, physicians, and other healthcare providers participating in these encounters.

Internal medicine in the United States and Germany: mutual influences from 1870 to today.

PubMed

Schulte-Bockolt, Arnd; Soergel, Konrad H; Stein, Juergen

2016-11-01

Over the past 140 years, the close academic and clinical interactions in Internal Medicine between German-speaking countries and the United States have been through three distinct stages. From 1870 until the First World War, German medical research, teaching, and university organization served as a model for U.S. medical schools and practice. However, after World War I, medical education reforms were implemented in the U.S., and due also to radical economic and political changes at home, German medicine lost its pioneering role. Furthermore, many scientists and clinicians were forced to emigrate in the face of racial and political persecution in Germany and Austria. Since the Second World War, American medicine has grown further to become the world leader in research, training, and clinical practice. The earlier trend of American physicians studying abroad was thus reversed, with many of today's foremost German physicians completing clinical and research training in the United States.

Experimental Validation of a Closed Brayton Cycle System Transient Simulation

NASA Technical Reports Server (NTRS)

Johnson, Paul K.; Hervol, David S.

2006-01-01

The Brayton Power Conversion Unit (BPCU) located at NASA Glenn Research Center (GRC) in Cleveland, Ohio was used to validate the results of a computational code known as Closed Cycle System Simulation (CCSS). Conversion system thermal transient behavior was the focus of this validation. The BPCU was operated at various steady state points and then subjected to transient changes involving shaft rotational speed and thermal energy input. These conditions were then duplicated in CCSS. Validation of the CCSS BPCU model provides confidence in developing future Brayton power system performance predictions, and helps to guide high power Brayton technology development.

Lan, Si; Fang, Ni; Lin, Hai Peng; Ye, Shi Qi

2018-06-01

With the promotion of the street system, residential quarters and units of the compound gradually open. In this paper, the relationship between traffic flow and traffic flow is established for external roads, and the road resistance model is established by internal roads. We propose a balanced distribution model from the two aspects of road opening conditions and traffic flow inside and outside the district, and quantitatively analyze the impact of the opening and closing on the surrounding roads. Finally, it puts forward feasible suggestions to improve the traffic situation and optimize the network structure.

The Non-innocent Phenalenyl Unit: An Electronic Nest to Modulate the Catalytic Activity in Hydroamination Reaction

Mukherjee, Arup; Sen, Tamal K.; Ghorai, Pradip Kr; Mandal, Swadhin K.

2013-01-01

The phenalenyl unit has played intriguing role in different fields of research spanning from chemistry, material chemistry to device physics acting as key electronic reservoir which has not only led to the best organic single component conductor but also created the spin memory device of next generation. Now we show the non-innocent behaviour of phenalenyl unit in modulating the catalytic behaviour in a homogeneous organic transformation. The present study establishes that the cationic state of phenalenyl unit can act as an organic Lewis acceptor unit to influence the catalytic outcome of intermolecular hydroamination reaction of carbodiimides. For the present study, we utilized organoaluminum complexes of phenalenyl ligands in which the phenalenyl unit maintains the closed shell electronic state. The DFT calculation reveals that the energy of LUMO of the catalyst is mainly controlled by phenalenyl ligands which in turn determines the outcome of the catalysis. PMID:24084653

Objective To describe a framework to assist pediatric intensive care unit physicians in conducting follow-up meetings with parents after their child's death. Many childhood deaths occur in pediatric intensive care units. Parents of children who die in pediatric intensive care units often desire a follow-up meeting with the physician(s) who cared for their child. Data Sources Prior research conducted by the Collaborative Pediatric Critical Care Research Network on the experiences and perspectives of bereaved parents and pediatric intensive care unit physicians regarding the desirability, content, and conditions of follow-up meetings. Results The framework includes suggestions for inviting families to follow-up meetings (i.e., developing an institutional system, invitation timing, and format); preparing for the meeting (i.e., assessing family preferences; determining location, attendees, and discussion topics; reviewing medical and psychosocial history); structure of the meeting (i.e., opening, closing, and developing a meeting agenda); communicating effectively during the meeting; and follow-up for both parents and physicians. Conclusion This framework is based on the experience and perspectives of bereaved parents and pediatric intensive care unit physicians. Future research should be conducted to determine the extent to which physician-parent follow-up meetings provide a benefit to parents, families, physicians, and other healthcare providers participating in these encounters.

2012-01-01

Background We aimed to establish levels of consumer involvement in randomised controlled trials (RCTs), meta-analyses and other studies carried out by the UK Medical Research Council (MRC) Clinical Trials Unit across the range of research programs, predominantly in cancer and HIV. Methods Staff responsible for studies that were included in a Unit Progress Report (MRC CTU, April 2009) were asked to complete a semi-structured questionnaire survey regarding consumer involvement. This was defined as active involvement of consumers as partners in the research process and not as subjects of that research. The electronic questionnaires combined open and closed questions, intended to capture quantitative and qualitative information on whether studies had involved consumers; types of activities undertaken; recruitment and support; advantages and disadvantages of involvement and its perceived impact on aspects of the research. Results Between October 2009 and April 2010, 138 completed questionnaires (86%) were returned. Studies had been conducted over a 20 year period from 1989, and around half were in cancer; 30% in HIV and 20% were in other disease areas including arthritis, tuberculosis and blood transfusion medicine. Forty-three studies (31%) had some consumer involvement, most commonly as members of trial management groups (TMG) [88%]. A number of positive impacts on both the research and the researcher were identified. Researchers generally felt involvement was worthwhile and some felt that consumer involvement had improved the credibility of the research. Benefits in design and quality, trial recruitment, dissemination and decision making were also perceived. Researchers felt they learned from consumer involvement, albeit that there were some barriers. Conclusions Whilst most researchers identified benefits of involving consumers, most of studies included in the survey had no involvement. Information from this survey will inform the development of a unit policy on consumer involvement, to guide future research conducted within the MRC Clinical Trials Unit and beyond. PMID:22243649

Thornton, Michael C.; Taylor, Robert Joseph; Chatters, Linda M.; Forsythe-Brown, Ivy

2016-01-01

African American and Black Caribbean relations dominate research on interactions across black ethnic divides. Using National Survey of American Life data, we explore a different aspect of black interethnic attitudes: how close these groups feel toward Africans. African Americans and Black Caribbeans were largely similar in their feelings of closeness to Africans. For Black Caribbeans, younger and male respondents, those reporting higher levels of financial strain, living in the northeast and persons who immigrated to the United States at least 11 years ago, report feeling especially close to Africans. Being male was the only significant correlate among African Americans. The findings are discussed in relation to how race, ethnicity and national origin shape personal identities within the U.S. and their significance for intergroup perceptions. These broader issues warrant further consideration in light of assertions that race as a defining feature of American life and intergroup relations is obsolete. PMID:28943747

Parallel Distributed Processing Theory in the Age of Deep Networks.

PubMed

Bowers, Jeffrey S

2017-12-01

Parallel distributed processing (PDP) models in psychology are the precursors of deep networks used in computer science. However, only PDP models are associated with two core psychological claims, namely that all knowledge is coded in a distributed format and cognition is mediated by non-symbolic computations. These claims have long been debated in cognitive science, and recent work with deep networks speaks to this debate. Specifically, single-unit recordings show that deep networks learn units that respond selectively to meaningful categories, and researchers are finding that deep networks need to be supplemented with symbolic systems to perform some tasks. Given the close links between PDP and deep networks, it is surprising that research with deep networks is challenging PDP theory. Copyright © 2017. Published by Elsevier Ltd.

Development and research program for a soil-based bioregenerative agriculture system to feed a four person crew at a Mars base

NASA Astrophysics Data System (ADS)

Silverstone, S.; Nelson, M.; Alling, A.; Allen, J.

For humans to survive during long-term missions on the Martian surface, bioregenerative life support systems including food production will decrease requirements for launch of Earth supplies, and increase mission safety. It is proposed that the development of ``modular biospheres''- closed system units that can be air-locked together and which contain soil-based bioregenerative agriculture, horticulture, with a wetland wastewater treatment system is an approach for Mars habitation scenarios. Based on previous work done in long-term life support at Biosphere 2 and other closed ecological systems, this consortium proposes a research and development program called Mars On Earth™ which will simulate a life support system designed for a four person crew. The structure will consist of /6 × 110 square meter modular agricultural units designed to produce a nutritionally adequate diet for 4 people, recycling all air, water and waste, while utilizing a soil created by the organic enrichment and modification of Mars simulant soils. Further research needs are discussed, such as determining optimal light levels for growth of the necessary range of crops, energy trade-offs for agriculture (e.g. light intensity vs. required area), capabilities of Martian soils and their need for enrichment and elimination of oxides, strategies for use of human waste products, and maintaining atmospheric balance between people, plants and soils.

Disparities in health, poverty, incarceration, and social justice among racial groups in the United States: a critical review of evidence of close links with neoliberalism.

PubMed

Nkansah-Amankra, Stephen; Agbanu, Samuel Kwami; Miller, Reuben Jonathan

2013-01-01

Problems of poverty, poor health, and incarceration are unevenly distributed among racial and ethnic minorities in the United States. We argue that this is due, in part, to the ascendance of United States-style neoliberalism, a prevailing political and economic doctrine that shapes social policy, including public health and anti-poverty intervention strategies. Public health research most often associates inequalities in health outcomes, poverty, and incarceration with individual and cultural risk factors. Contextual links to structural inequality and the neoliberal doctrine animating state-sanctioned interventions are given less attention. The interrelationships among these are not clear in the extant literature. Less is known about public health and incarceration. Thus, the authors describe the linkages between neoliberalism, public health, and criminal justice outcomes. We suggest that neoliberalism exacerbates racial disparities in health, poverty, and incarceration in the United States. We conclude by calling for a new direction in public health research that advances a pro-poor public health agenda to improve the general well-being of disadvantaged groups.

Designing Research Services: Cross-Disciplinary Administration and the Research Lifecycle

NASA Astrophysics Data System (ADS)

Madden, G.

2017-12-01

The sheer number of technical and administrative offices involved in the research lifecycle, and the lack of shared governance and shared processes across those offices, creates challenges to the successful preservation of research outputs. Universities need a more integrated approach to the research lifecycle that allows us to: recognize a research project as it is being initiated; identify the data associated with the research project; document and track any compliance, security, access, and publication requirements associated with the research and its data; follow the research and its associated components across the research lifecycle; and finally recognize that the research has come to a close so we can trigger the various preservation, access, and communications processes that close the loop, inform the public, and promote the continued progress of science. Such an approach will require cooperation, communications, and shared workflow tools that tie together (often across many years) PIs, research design methodologists, grants offices, contract negotiators, central research administrators, research compliance specialists, desktop IT support units, server administrators, high performance computing facilities, data centers, specialized data transfer networks, institutional research repositories, institutional data repositories, and research communications groups, all of which play a significant role in the technical or administrative success of research. This session will focus on progress towards improving cross-disciplinary administrative and technical cooperation at Penn State University, with an emphasis on generalizable approaches that can be adopted elsewhere.

The neurovascular unit - concept review.

PubMed

Muoio, V; Persson, P B; Sendeski, M M

2014-04-01

The cerebral hyperaemia is one of the fundamental mechanisms for the central nervous system homeostasis. Due also to this mechanism, oxygen and nutrients are maintained in satisfactory levels, through vasodilation and vasoconstriction. The brain hyperaemia, or coupling, is accomplished by a group of cells, closely related to each other; called neurovascular unit (NVU). The neurovascular unit is composed by neurones, astrocytes, endothelial cells of blood-brain barrier (BBB), myocytes, pericytes and extracellular matrix components. These cells, through their intimate anatomical and chemical relationship, detect the needs of neuronal supply and trigger necessary responses (vasodilation or vasoconstriction) for such demands. Here, we review the concepts of NVU, the coupling mechanisms and research strategies. © 2014 Scandinavian Physiological Society. Published by John Wiley & Sons Ltd.

Partnership research models are useful for achieving the integration of CCS and EBP, since they involve close observation of and participation by clinicians and practitioners in the research process, and often use integrated qualitative and quantitative mixed methods. We illustrate this with 3 examples of work that can help integrate CCS and EBP: ongoing collection of information from patients, clinicians and staff, or "evidence farming"; close study and continuous improvement of activities and accommodations; and use of evidence of tacit, implicit cultural scripts and norms, such as being "productive," as well as explicit scripts. From a research practice point of view, collaborative partnerships will likely produce research with culture and context bracketed in, and will contribute stronger research models, methods, and units of analysis. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

According to the opinion of many researchers, a culture of microalgae may serve as a regenerator of atmosphere in the cabin of a spaceship. To use microalgae for these objectives, it was necessary to have an automatic unit possessing a high productivity of the cultivation process. This unit, containing a minimum of equipment, enables carrying on for an unlimited time the cultivation of algae without a drop in their productivity. The unit meeting these requirements (the cultivator) was developed by the authors and will be described in the presentation. The stability of the microalga photosynthetic system is characterized by the fact that after 70% biosynthesis repression by the ultraviolet radiation, a full regeneration of the productivity level takes place within 24 hours. In our experiments the system was functioning with the stable estimated productivity for many days (up to two months without interruption). During the process, no biological inhibitions to permanent performance and further prolongation of its life were found. As to the productivity, stability and control, the described biotechnological method may appear to be useful as a link of the closed ecosystem.

Enhancing US-Japan Cooperation to Combat Antimicrobial Resistance

PubMed Central

2014-01-01

The Global Health Security Agenda (GHSA) is aimed at preventing, detecting, and responding to infectious disease threats. To move toward these goals, the United States has committed to partner with at least 30 countries around the world. One of the objectives of the GHSA includes “[p]reventing the emergence and spread of antimicrobial drug resistant organisms.” Antimicrobial resistance (AMR) has become a growing global health security problem, with inappropriate use of antimicrobial medications in humans and animals and a lack of new antimicrobial medications contributing to this problem. While AMR is a growing global concern, working on it regionally can make this multifaceted problem more manageable. The United States and Japan, both world leaders in the life sciences, are close allies that have established cooperative programs in medical research and global health that can be used to work on combating AMR and advance the GHSA. Although the United States and Japan have cooperated on health issues in the past, their cooperation on the growing problem of AMR has been limited. Their existing networks, cooperative programs, and close relationships can and should be used to work on combating this expanding problem. PMID:25470465

Local knowledge, environmental politics, and the founding of ecology in the United States. Stephen Forbes and "The Lake as a Microcosm" (1887).

PubMed

Schneider, D W

2000-12-01

Stephen Forbes's "The Lake as a Microcosm" is one of the founding documents of the science of ecology in the United States. By tracing the connections between scientists and local fishermen underlying the research on floodplain lakes presented in "The Lake as a Microcosm," this essay shows how the birth of ecology was tied to local knowledge and the local politics of environmental transformation. Forbes and the other scientists of the Illinois Natural History Survey relied on fishermen for manual labor, expertise in catching fish, and knowledge of the natural history of the fishes. As Forbes and his colleagues worked in close contact with fishermen, they also adopted many of their political concerns over the privatization of the floodplain and became politically active in supporting their interests. The close connection between scientists and local knowledge forced the ecologists to reframe the boundaries of ecology as objective or political, pure or applied, local or scientific.

Vibration test data from an operating 2 kWe closed-Brayton-cycle (CBC) power conversion system (PCS) located at the NASA Glenn Research Center was used for a comparison with a dynamic disturbance model of the same unit. This effort was performed to show that a dynamic disturbance model of a CBC PCS can be developed that can accurately predict the torque and vibration disturbance fields of such class of rotating machinery. The ability to accurately predict these disturbance fields is required before such hardware can be confidently integrated onto a spacecraft mission. Accurate predictions of CBC disturbance fields will be used for spacecraft control/structure interaction analyses and for understanding the vibration disturbances affecting the scientific instrumentation onboard. This paper discusses how test cell data measurements for the 2 kWe CBC PCS were obtained, the development of a dynamic disturbance model used to predict the transient torque and steady state vibration fields of the same unit, and a comparison of the two sets of data.

As indoor mobile navigation suffers from low positioning accuracy and accumulation error, we carried out research into an integrated location system for a robot based on Kinect and an Inertial Measurement Unit (IMU). In this paper, the close-range stereo images are used to calculate the attitude information and the translation amount of the adjacent positions of the robot by means of the absolute orientation algorithm, for improving the calculation accuracy of the robot's movement. Relying on the Kinect visual measurement and the strap-down IMU devices, we also use Kalman filtering to obtain the errors of the position and attitude outputs, in order to seek the optimal estimation and correct the errors. Experimental results show that the proposed method is able to improve the positioning accuracy and stability of the indoor mobile robot.

3. A Closed Aquatic System for Space and Earth Application

NASA Astrophysics Data System (ADS)

Slenzka, K.; Duenne, M.; Jastorff, B.; Ranke, J.; Schirmer, M.

Increased durations in space travel as well as living in extreme environments are requiring reliable life support systems in general and bioregenerative ones in detail. Waste water management, air revitalization and food production are obviously center goals in this research, however, in addition a potential influence by chemicals, drugs etc. released to the closed environment must be considered. On this basis ecotoxicological data become more and more important for CELSS (Closed Ecological Life Support System) development and performance. The experiences gained during the last years in our research group lead to the development of an aquatic habitat, called AquaHab (formerly CBRU), which is a closed, self-sustaining system with a total water volume of 9 liters. In the frame program of a R&D project funded by the state of Bremen and OHB System, AquaHab is under adaptation to become an ecotoxicological research unit containing for example Japanese Medaka or Zebra Fish, amphipods, water snails and water plants. Test runs were standardized and analytical methods were developed. Beside general biological and water chemical parameters, activity measurements of biotransforming enzymes (G6PDH, CytP450-Oxidase, Peroxidase) and cell viability tests as well as residual analysis of the applied substance and respective metabolites were selected as evaluation criteria. In a first series of tests low doses effects of TBT (Tributyltin, 0.1 to 20 μgTBT/l nominal concentration) were analyzed. The AquaHab and data obtained for applied environmental risk assessment will be presented at the assembly.

The purpose of this study was to gain insight into the use and storage of supplies in the neonatal intensive care and women's health units of Parkland Hospital in Dallas, Texas. Construction of a new Parkland Hospital is underway, with completion of the 862-bed, 2.5-million square feet hospital in 2014. Leaders from the hospital and representatives from one of its major vendors collaborated on a research study to evaluate the hospital's current supply management system and develop criteria to create an improved system to be implemented at the new hospital. Approach includes qualitative and quantitative methods, that is, written survey, researcher observations, focus groups, and evaluation of hospital supply reports. Approaching the ideal location of supplies can be best approached by defining a nurse's activity at the point of care. Determining an optimal supply management system must be approached by understanding the "what" of caregivers' activities and then determining the "where" of the supplies that support those activities. An ideal supply management system locates supplies as close as possible to the point of use, is organized by activity, and is standardized within and across units. © The Author(s) 2015.

Radiation Protection

NASA Astrophysics Data System (ADS)

Grupen, Claus

Radiation protection is a very important aspect for the application of particle detectors in many different fields, like high energy physics, medicine, materials science, oil and mineral exploration, and arts, to name a few. The knowledge of radiation units, the experience with shielding, and information on biological effects of radiation are vital for scientists handling radioactive sources or operating accelerators or X-ray equipment. This article describes the modern radiation units and their conversions to older units which are still in use in many countries. Typical radiation sources and detectors used in the field of radiation protection are presented. The legal regulations in nearly all countries follow closely the recommendations of the International Commission on Radiological Protection (ICRP). Tables and diagrams with relevant information on the handling of radiation sources provide useful data for the researcher working in this field.

Development and research program for a soil-based bioregenerative agriculture system to feed a four person crew at a Mars base.

2003-01-01

For humans to survive during long-term missions on the Martian surface, bioregenerative life support systems including food production will decrease requirements for launch of Earth supplies, and increase mission safety. It is proposed that the development of "modular biospheres"--closed system units that can be air-locked together and which contain soil-based bioregenerative agriculture, horticulture, with a wetland wastewater treatment system is an approach for Mars habitation scenarios. Based on previous work done in long-term life support at Biosphere 2 and other closed ecological systems, this consortium proposes a research and development program called Mars On Earth(TM) which will simulate a life support system designed for a four person crew. The structure will consist of 6 x 110 square meter modular agricultural units designed to produce a nutritionally adequate diet for 4 people, recycling all air, water and waste, while utilizing a soil created by the organic enrichment and modification of Mars simulant soils. Further research needs are discussed, such as determining optimal light levels for growth of the necessary range of crops, energy trade-offs for agriculture (e.g. light intensity vs. required area), capabilities of Martian soils and their need for enrichment and elimination of oxides, strategies for use of human waste products, and maintaining atmospheric balance between people, plants and soils. c2002 COSPAR.

Research ethics across the 49th parallel: the potential value of pilot testing "equivalent protections" in Canadian research institutions.

PubMed

Lavery, James V; McDonald, Michael; Meslin, Eric M

2005-01-01

Canada and the United States share the world's largest trade partnership and an increasing concern about divergent regulatory approaches to common industries. Canadian research institutes receive more research funding from the U.S. National Institutes of Health than any other country, much of it to fund multi-centre and collaborative research between the two countries. Because of these close economic and research ties, and the extensive similarities between the two countries in the review and oversight of ethics in human subjects research, we propose that Canada would be an ideal country for a pilot-test of the feasibility of "equivalent protections," a U.S. regulation that permits comparison of protections for human subjects between institutions in the two countries. The "equivalent protections" has been advocated by various bodies in the United States as a potentially beneficial mechanism for improving oversight of foreign trials. As well, we argue that "equivalent protections" could prove to be valuable for Canada in five specific ways: (1) by potentially reducing administrative burden on Canadian research institutions administering U.S. federal research funding; (2) by creating symbolic value of an explicit recognition by the United States that procedures normally followed for the protection of human subjects in Canadian research institutions are at least equivalent to those provided by the U.S. regulations; (3) by lowering the opportunity cost of investing in research in Canada; (4) by affording Canada an opportunity to enhance its leadership role in international research by offering an alternative to the U.S. regulatory model for the protection of human subjects; and (5) by providing a model for how the idea of equivalent protections might be addressed for research funded by Canadian agencies but conducted in other countries.

Felt Obligation to Help Others as a Protective Factor Against Losses in Psychological Well-being Following Functional Decline in Middle and Later Life

PubMed Central

2009-01-01

This study examined felt obligation to help others in two domains (close others and society) as protective factors against losses in psychological well-being following functional decline. Lagged-dependent regression models were estimated using data from 849 respondents aged 35–74 years and without any functional limitations at baseline in the 1995–2005 National Survey of Midlife in the United States. Greater felt obligation to help close others protected against declining self-acceptance in the face of more severe functional decline, and greater felt obligation to help society protected against declining personal growth and self-acceptance. Greater felt obligation to help close others and society protected against increasing depressive symptoms at younger ages in adulthood. Findings suggest the importance for additional research on how aspects of altruism can promote psychological adaptation to declining functional health in middle and later life. PMID:19825942

A liquid-delivery device that provides precise reward control for neurophysiological and behavioral experiments.

PubMed

Mitz, Andrew R

2005-10-15

Behavioral neurophysiology and other kinds of behavioral research often involve the delivery of liquid rewards to experimental subjects performing some kind of operant task. Available systems use gravity or pumps to deliver these fluids, but such methods are poorly suited to moment-to-moment control of the volume, timing, and type of fluid delivered. The design described here overcomes these limitations using an electronic control unit, a pressurized reservoir unit, and an electronically controlled solenoid. The control unit monitors reservoir pressure and provides precisely timed solenoid activation signals. It also stores calibration tables and does on-the-fly interpolation to support computer-controlled delivery calibrated directly in milliliters. The reservoir provides pressurized liquid to a solenoid mounted near the subject. Multiple solenoids, each supplied by a separate reservoir unit and control unit, can be stacked in close proximity to allow instantaneous selection of which liquid reward is delivered. The precision of droplet delivery was verified by weighing discharged droplets on a commercial analytical balance.

The air transportation industry birthplace of reliability-centered maintenance

The 1980s and 1970s provided a timely opportunity for examining and radically changing the process called {open_quotes}preventive maintenance{close_quotes} as it is applied to the aircraft used for scheduled air transportation. The Federal Aviation Administration and four major airlines, United, American, Pan American and Trans World, were the {open_quotes}principals{close_quotes} in that process. While United`s work with the FAA on the Boeing 737 had opened the door a crack, the Boeing 747 presented a major opportunity to radically improve the process for maintenance program design. That program was guided by the results of United`s analyses of failure data from operations of severalmore » fleets, each larger than 100 aircraft, and the concurrent experience of American, Pan American and Trans World. That knowledge provided the insights necessary to support an entirely different approach to maintenance program design. As a result, while United`s existing maintenance program required scheduled overhaul of 339 items on each DC-8, it required overhaul of only 8 items on the B-7471 Although the initial thrust of that work focused on components of active systems, there was concurrent work focused on items whose principal function was to carry the loads associated with operations. That program focused on the classification of structurally-significant items and their classification as {open_quotes}safe life{close_quotes} or {open_quotes}damage tolerant{close_quote} to determine what periodic replacements or repeated inspections were required. That work came to the attention of the Department of Defense which supported preparation of the book-length report by F. Stanley Nowlan and Howard F.

Westfall, Catherine

2003-03-01

Historians of science have tended to focus exclusively on scale in investigations of largescale research, perhaps because it has been easy to assume that comprehending a phenomenon dubbed "Big Science" hinges on an understanding of bigness. A close look at Lawrence Berkeley Laboratory's Bevalac, a medium-scale "mezzo science" project formed by uniting two preexisting machines--the modest SuperHILAC and the grand Bevatron--shows what can be gained by overcoming this preoccupation with bigness. The Bevalac story reveals how interconnections, connections, and disconnections ultimately led to the development of a new kind of science that transformed the landscape of large-scale research in the United States. Important lessons in historiography also emerge: the value of framing discussions in terms of networks, the necessity of constantly expanding and refining methodology, and the importance of avoiding the rhetoric of participants and instead finding words to tell our own stories.

According to the recent worldwide estimation by the GLOBOCAN project, in total, 12.7 million new cancer cases and 7.6 million cancer deaths occurred in 2008. The worldwide number of cancer survivors within 5 years of diagnosis has been estimated at be almost 28.8 million. Informal caregivers, such as family members and close friends, provide essential support to cancer patients. The authors of this report provide an overview of issues in the study of informal caregivers for cancer patients and long-term survivors in the United States and Europe, characterizing the caregivers commonly studied; the resources currently available to them; and their unmet needs, their psychosocial outcomes, and the psychosocial interventions tailored to their special circumstances. A broad overview of the state of research and knowledge, both in Europe and the United States, and observations on the directions for future research are provided. PMID:23695928

2011-01-01

The present article presents a comprehensive review and analysis of quantitative research conducted in the United States on chaplaincy and closely related topics published between 2000 and 2009. A combined search strategy identified 49 quantitative studies in 13 journals. The analysis focuses on the methodological sophistication of the studies, compared to earlier research on chaplaincy and pastoral care. Cross-sectional surveys of convenience samples still dominate the field, but sample sizes have increased somewhat over the past three decades. Reporting of the validity and reliability of measures continues to be low, although reporting of response rates has improved. Improvements in the use of inferential statistics and statistical controls were also observed, compared to previous research. The authors conclude that more experimental research is needed on chaplaincy, along with an increased use of hypothesis testing, regardless of the research designs that are used.

Origami Metamaterial based on Pattern Rigidity

NASA Astrophysics Data System (ADS)

Chen, Yan; You, Zhong

Origami inspired mechanical metamaterials are made from a tessellation of origami units. Their mechanical behaviour is closely related to the behaviour of the origami units used. In this article, we focus on a family of metamaterials that are created by the tessellation of the square twist origami units. Generally a square twist origami unit can have four distinct hill-valley crease arrangements, two of which are rigidly foldable whereas the others are not. The rigidly foldable unit has, in general, lower stiffness than that of the non-rigidly foldable one if the facets can easily rotate about the creases. We shall show that it is possible to put rigidly foldable and non-rigidly foldable units together to form a geometrically compatible tessellation, and the stiffness of the overall structure based on such a tessellation is primarily decided by the number of non-rigid units. By astutely placing such units in a tessellation, we are able to create a metamaterial with a tunable stiffness.

Laboratory research shows that eye-closure during memory retrieval improves both the amount and the factual accuracy of memory reports about witnessed events. Based on these findings, we developed the Eye-Closure Interview, and examined its feasibility (in terms of compliance with the instructions) and effectiveness (in terms of the quantity and quality of reported information) in eyewitness interviews conducted by the South African Police Service. Police interviewers from the Facial Identification Unit were randomly assigned to receive Eye-Closure Interview training or no training. We analyzed 95 interviews with witnesses of serious crimes (including robbery, rape, and murder), some of whom were instructed to close their eyes during salient parts of the interview. Witnesses in the control condition rarely spontaneously closed their eyes, but witnesses in the Eye-Closure Interview condition kept their eyes closed during 97% of their descriptions, suggesting that the Eye-Closure Interview would be easy to implement in a field setting. Although witnesses who closed their eyes did not remember more information overall, the information they provided was considered to be of significantly greater forensic relevance (as reflected in 2 independent blind assessments, 1 by a senior police expert and 1 by a senior researcher). Thus, based on the findings from this field study and from previous laboratory research, we conclude that implementation of the Eye-Closure Interview in witness interviews would help police interviewers to elicit more valuable information from witnesses, which could be relevant to the police investigation and/or in court.

Effects of eliminating psychiatric rehabilitation from the secure levels of a mental-health service system.

2013-11-01

Psychiatric rehabilitation (PR) is widely recognized as a treatment approach and an array of evidence-based practices effective for promoting the recovery of people with serious mental illness (SMI). However, its use in institutional settings is not widespread for unclear reasons. Policymakers may sometimes believe the superiority of PR in controlled research does not apply in the real world, for various reasons. This study exploits an unusual set of real-world circumstances surrounding the closure of a well-developed PR program in a state hospital. The program was closed after a period of mental-health services reform that significantly augmented the surrounding community-service system. The PR program was converted to conventional medical-institutional model-treatment units with no reduction in beds or funding within the state hospital. A database composed of public documents was used to analyze the consequences of the closing. Within the institution, the consequences included a persistent presence of long-term difficult-to-discharge patients, a slowed discharge rate, a net increase in the hospital's per capita treatment costs, and higher use of restraint/seclusion. Effects were also detectable in the surrounding mental-health service system, including degraded outcome of community-based step-down services and increased pressure on emergency/crisis services. The consequences of closing the program are consistent with expectations based on research, and demonstrate danger in assuming that real world exigencies obviate research findings.

Prohibited or regulated? LSD psychotherapy and the United States Food and Drug Administration.

PubMed

Oram, Matthew

2016-09-01

Over the 1950s and early 1960s, the use of the hallucinogenic drug lysergic acid diethylamide (LSD) to facilitate psychotherapy was a promising field of psychiatric research in the USA. However, during the 1960s, research began to decline, before coming to a complete halt in the mid-1970s. This has commonly been explained through the increase in prohibitive federal regulations during the 1960s that aimed to curb the growing recreational use of the drug. However, closely examining the Food and Drug Administration's regulation of LSD research in the 1960s will reveal that not only was LSD research never prohibited, but that the administration supported research to a greater degree than has been recognized. Instead, the decline in research reflected more complex changes in the regulation of pharmaceutical research and development. © The Author(s) 2016.

　An increasing number of cases of research misconduct and whistle-blowing in the fields of medicine and life sciences has created public concern about research integrity. In Europe and the United States, there has been a large focus on poor reproducibility in life science research, and poor reproducibility is largely associated with research misconduct. Research integrity is equally crucial in the pharmaceutical sciences, which play an important role in medical and life sciences. Individual cases of research misconduct have not been investigated in detail in Japan, because it was generally believed that only researchers with strong or strange personalities would participate in misconduct. However, a better understanding of research misconduct will enable more in-depth discussions about research integrity, which is now known to be closely associated with normal research activities. Here I will introduce information on various contemporary activities being performed to create a sound research environment, drawn from practices in universities, pharmaceutical companies, and government agencies. I will also discuss ways in which individual researchers can promote research integrity.

The Ambient and Perturbed Solar Wind: From the Sun to 1 AU

Steinolfson, R. S.

1997-01-01

The overall objective of the proposed research was to use numerical solutions of the magnetohydrodynamic (MHD) equations along with comparisons of the computed results with observations to study the following topics: (1) ambient solar wind solutions that extend from the solar surface to 1 astronomical unit (AU), contain closed magnetic structures near the Sun, and are consistent with observed values; (2) magnetic and plasma structures in coronal mass ejections (CMES) as they propagate to the interplanetary medium; (3) relation of MHD shocks to CMEs in the interplanetary medium; (4) interaction of MHD shocks with structures (such as other shocks, corotating interaction regions, current sheets) in the interplanetary plasma; and (5) simulations of observed interplanetary structures. A planned close collaboration with data analysts served to make the model more relevant to the data. The outcome of this research program is an improved understanding of the physical processes occurring in solar-generated disturbances in the interplanetary medium between the Sun and 1 AU.

2003-01-01

Several major airports around the United States have, or plan to have, closely-spaced parallel runways. This project complemented current and previous research by examining the pilots ability to control their position longitudinally within their approach stream.This project s results considered spacing for separation from potential positions of wake vortices from the parallel approach. This preventive function could enable CSPA operations to very closely spaced runways. This work also considered how pilot involvement in longitudinal spacing could allow for more efficient traffic flow, by allowing pilots to keep their aircraft within tighter arrival slots then air traffic control (ATC) might be able to establish, and by maintaining space within the arrival stream for corresponding departure slots. To this end, this project conducted several research studies providing an analytic and computational basis for calculating appropriate aircraft spacings, experimental results from a piloted flight simulator test, and an experimental testbed for future simulator tests. The following sections summarize the results of these three efforts.

Several National Park Service units in the Intermountain region possess a number of closely related management needs relative to the abundance of wild ungulates and their herbivory effects on plants and ecosystem processes. In 1993, the then National Biological Service (NBS) - now U.S. Geological Survey, Biological Resources Discipline (USGS, BRD)­ initiated a series of research studies in four park units in the Intermountain West., into the abundance and effects of ungulates on park ecosystems. Each of these parks received a number of similar research study elements including: (a) a number of new ungulate grazing exclosures (n = 12-21 exclosures per park); (b) aerial survey sightability models to estimate population sizes of ungulates; (e) measures of biomass production and consumption rates near the exclosures and across the landscape; (d) studies of the effects of the grazing on plant abundance, species diversity, and ecosystem effects; and (e) computer model simulations (SAVANNA) of the effects on the ecosystem and plant resources of different ungulate management scenarios. One park unit, Rocky Mountain National Park, Colorado, received funding from the U.S. Geological Survey (USGS, BRD) and parallel funding from NPS for an intensive research study of the effects of elk on the park ecosystems.

Ethical Considerations in Research Participation Virality.

PubMed

Ellis-Barton, Carol

2016-07-01

This article seeks to commence and encourage discussion around the upcoming ethical challenges of virality in network structures. When the call for participation in a research project on lupus in Ireland went from an advertisement in a newsletter to a meme (unit of transmissible information) on a closed Facebook page, the ethical considerations of virality were raised. The article analyzes the Association of Internet Researchers guidelines, Facebook policies, and the context of privacy in relation to virality. Virality creates the leverage for methodological pluralism. The nature of the inquiry can determine the method rather than the other way around. Viral ethical considerations are evolving due to the cyber world becoming the primary meme of communication, with flexibility in the researcher's protocol providing opportunities for efficient, cost-effective, and diverse recruitment. © The Author(s) 2016.

Where does good quality qualitative health care research get published?

PubMed

Richardson, Jane C; Liddle, Jennifer

2017-09-01

This short report aims to give some insight into current publication patterns for high-quality qualitative health research, using the Research Excellence Framework (REF) 2014 database. We explored patterns of publication by range and type of journal, by date and by methodological focus. We also looked at variations between the publications submitted to different Units of Assessment, focussing particularly on the one most closely aligned with our own research area of primary care. Our brief analysis demonstrates that general medical/health journals with high impact factors are the dominant routes of publication, but there is variation according to the methodological approach adopted by articles. The number of qualitative health articles submitted to REF 2014 overall was small, and even more so for articles based on mixed methods research, qualitative methodology or reviews/syntheses that included qualitative articles.

Initial Closed Operation of the CELSS Test Facility Engineering Development Unit

Kliss, Mark

1995-01-01

As part of the NASA Controlled Ecological Life Support System (CELSS) Program, a CELSS Test Facility (CTF) is being planned for installation on the Space Station. The CTF will be used to provide data on the productivity and efficiency of a variety of CELSS higher plant crops grown sequentially from seed to harvest in the microgravity environment of the Space Station. Stringent environmental control will be maintained while fundamental crop productivity issues, such as carbon dioxide uptake and oxygen production rates, water transpiration rates, and biomass accumulation rates are obtained for comparison with ground-based data. In order to obtain an early realistic determination of the subsystem and system requirements necessary to provide the appropriate environmental conditions specified for CTF crop productivity experiments, an Engineering Development Unit (EDU) has been constructed and is undergoing initial operational testing at NASA Ames Research Center. The EDU is a ground-based testbed which will be used to characterize the integrated performance of major subsystem technologies, to evaluate hardware candidates and control strategies required for the CTF, and to further define the ability to meet CTF requirements within present Space Station constraints. This paper describes the initial closed operational testing of the EDU. Measured performance data are compared with the specified functional requirements and results from initial closed testing are presented. Plans for future science and technology testing are discussed.

The portable Contamination Analysis Unit (CAU) measures trace quantities of surface contamination in real time. The detector head of the portable contamination analysis unit has an opening with an O-ring seal, one or more vacuum valves and a small mass spectrometer. With the valve closed, the mass spectrometer is evacuated with one or more pumps. The O-ring seal is placed against a surface to be tested and the vacuum valve is opened. Data is collected from the mass spectrometer and a portable computer provides contamination analysis. The CAU can be used to decontaminate and decommission hazardous and radioactive surfaces by measuring residual hazardous surface contamination, such as tritium and trace organics. It provides surface contamination data for research and development applications as well as real-time process control feedback for industrial cleaning operations and can be used to determine the readiness of a surface to accept bonding or coatings. 1 fig.

Policy makers continue to debate whether or not to increase the share of health care expenditures in United Kingdom. On the other hand, the pressure of operating within tight budgets and the advances in technology are forcing more locally based hospitals to close. One that could be used by policy makers as a benchmark is the measure of relative performance of hospitals. Many researchers have examined the source of inefficiency in health sectors (see, for example, Harris et al., Oper. Res. Soc. 57:801-811, 2000, Ozcan et al., Med. Case 30:781-784, 1992; Ozcan et aL., J. Med. Syst. 20(3)141-150, 1996; and Grosskopf and Valdmanis, J. Health. Econ. 6:89-107, 1987 but there is no evidence of measuring performance of neonatal care units of Scottish hospitals in the DEA literature. The purpose of this paper is to measure both technical and scale efficiency using data envelopment analysis in a selection of 22 neonatal care units in Scotland. The analysis suggests that major inefficiency likely exists in health care production in United Kingdom. There is potential for improving productivity by 20%.

Massey, J. L.

1976-01-01

Work on partial unit memory codes continued; it was shown that for a given virtual state complexity, the maximum free distance over the class of all convolutional codes is achieved within the class of unit memory codes. The effect of phase-lock loop (PLL) tracking error on coding system performance was studied by using the channel cut-off rate as the measure of quality of a modulation system. Optimum modulation signal sets for a non-white Gaussian channel considered an heuristic selection rule based on a water-filling argument. The use of error correcting codes to perform data compression by the technique of syndrome source coding was researched and a weight-and-error-locations scheme was developed that is closely related to LDSC coding.

Theory and experiment research for ultra-low frequency maglev vibration sensor.

PubMed

Zheng, Dezhi; Liu, Yixuan; Guo, Zhanshe; Zhao, Xiaomeng; Fan, Shangchun

2015-10-01

A new maglev sensor is proposed to measure ultra-low frequency (ULF) vibration, which uses hybrid-magnet levitation structure with electromagnets and permanent magnets as the supporting component, rather than the conventional spring structure of magnetoelectric vibration sensor. Since the lower measurement limit needs to be reduced, the equivalent bearing stiffness coefficient and the equivalent damping coefficient are adjusted by the sensitivity unit structure of the sensor and the closed-loop control system, which realizes both the closed-loop control and the solving algorithms. A simple sensor experimental platform is then assembled based on a digital hardware system, and experimental results demonstrate that the lower measurement limit of the sensor is increased to 0.2 Hz under these experimental conditions, indicating promising results of the maglev sensor for ULF vibration measurements.

Relational mobility explains between- and within-culture differences in self-disclosure to close friends.

PubMed

Schug, Joanna; Yuki, Masaki; Maddux, William

2010-10-01

In the current research, we tested a novel explanation for previously demonstrated findings that East Asians disclose less personal information to other people than do Westerners. We propose that both between- and within-culture differences in self-disclosure to close friends may be explained by the construct of relational mobility, the general degree to which individuals in a society have opportunities to form new relationships and terminate old ones. In Study 1, we found that cross-cultural differences (Japan vs. United States) in self-disclosure to a close friend were mediated by individuals' perceptions of relational mobility. In Study 2, two separate measures of relational mobility predicted self-disclosure within a single culture (Japan), and this relationship was mediated by the motivation to engage in self-disclosure to strengthen personal relationships. We conclude that societies and social contexts higher in relational mobility (in which relationships can be formed and dissolved relatively easily) produce stronger incentives for self-disclosure as a social-commitment device.

Cultural Differences in Professional Help Seeking: A Comparison of Japan and the U.S.

Mojaverian, Taraneh; Hashimoto, Takeshi; Kim, Heejung S.

2013-01-01

Previous research has found cultural differences in the frequency of support seeking. Asians and Asian Americans report seeking support from their close others to deal with their stress less often compared to European Americans. Similarly, other research on professional help seeking has shown that Asians and Asian Americans are less likely than European Americans to seek professional psychological help. Previous studies link this difference to multitude of factors, such as cultural stigma and reliance on informal social networks. The present research examined another explanation for cultural differences in professional help seeking. We predicted that the observed cultural difference in professional help seeking is an extension of culture-specific interpersonal relationship patterns. In the present research, undergraduate students in Japan and the United States completed the Inventory of Attitudes toward Seeking Mental Health Services, which measures professional help seeking propensity, psychological openness to acknowledging psychological problems, and indifference to the stigma of seeking professional help. The results showed that Japanese reported greater reluctance to seek professional help compared to Americans. Moreover, the relationship between culture and professional help seeking attitudes was partially mediated by use of social support seeking among close others. The implications of cultural differences in professional help seeking and the relationship between support seeking and professional help seeking are discussed. PMID:23426857

Faculty productivity is essential for academic medical centers striving to achieve excellence and national recognition. The objective of this study was to evaluate whether and how academic Departments of Medicine in the United States measure faculty productivity for the purpose of salary compensation. We surveyed the Chairs of academic Departments of Medicine in the United States in 2012. We sent a paper-based questionnaire along with a personalized invitation letter by postal mail. For non-responders, we sent reminder letters, then called them and faxed them the questionnaire. The questionnaire included 8 questions with 23 tabulated close-ended items about the types of productivity measured (clinical, research, teaching, administrative) and the measurement strategies used. We conducted descriptive analyses. Chairs of 78 of 152 eligible departments responded to the survey (51% response rate). Overall, 82% of respondents reported measuring at least one type of faculty productivity for the purpose of salary compensation. Amongst those measuring faculty productivity, types measured were: clinical (98%), research (61%), teaching (62%), and administrative (64%). Percentages of respondents who reported the use of standardized measurements units (e.g., Relative Value Units (RVUs)) varied from 17% for administrative productivity to 95% for research productivity. Departments reported a wide variation of what exact activities are measured and how they are monetarily compensated. Most compensation plans take into account academic rank (77%). The majority of compensation plans are in the form of a bonus on top of a fixed salary (66%) and/or an adjustment of salary based on previous period productivity (55%). Our survey suggests that most academic Departments of Medicine in the United States measure faculty productivity and convert it into standardized units for the purpose of salary compensation. The exact activities that are measured and how they are monetarily compensated varied substantially across departments.

Large Unmanned Aircraft System Operations in the National Airspace System - the NASA 2007 Western States Fire Missions

The National Aeronautics and Space Administration (NASA) Dryden Flight Research Center (DFRC) Ikhana (ee-kah-nah) project executed the 2007 Western States Fire Missions over several of the western United States using an MQ-9 unmanned aircraft system (UAS) in partnership with the NASA Ames Research Center, the United States Forest Service, and the National Interagency Fire Center. The missions were intended to supply infrared imagery of wildfires to firefighters on the ground within 10 minutes of data acquisition. For each of the eight missions, the NASA DFRC notified the Federal Aviation Administration (FAA) of specific flight plans within three or fewer days of the flight. The FAA Certificate of Waiver or Authorization (commonly referred to as a COA ) process was used to obtain access to the United States National Airspace System. Significant time and resources were necessary to develop the COA application, perform mission planning, and define and approve emergency landing sites. Unique aspects of flying unmanned aircraft created challenges to mission operations. Close coordination with FAA headquarters and air traffic control resulted in safe and successful missions that assisted firefighters by providing near-real-time imagery of selected wildfires.

Mechanisms involved in the psychological distress of Black Caribbeans in the United States

NASA Astrophysics Data System (ADS)

Govia, Ishtar O.

The mental health of ethnic minorities in the United States is of urgent concern. The accelerated growth of groups of ethnic minorities and immigrants in the United States and the stressors to which they are exposed, implores academic researchers to investigate more deeply health disparities and the factors that exacerbate or minimize such inequalities. This dissertation attended to that concern. It used data from the National Survey of American Life (NSAL), the first survey with a national representative sample of Black Caribbeans, to explore mechanisms that involved in the psychological distress of Black Caribbeans in the United States. In a series of three studies, the dissertation investigated the role and consequence of (1) chronic discrimination, immigration factors, and closeness to ethnic and racial groups; (2) personal control and social support; and (3) family relations and social roles in the psychological distress of Black Caribbeans. Study 1 examined how the associations between discrimination and psychological distress were buffered or exacerbated by closeness to ethnic group and closeness to racial group. It also examined how these associations differed depending on immigration factors. Results indicated that the buffering or exacerbating effect of ethnic and racial group closeness varied according to the type of discrimination (subtle or severe) and were more pronounced among those born in the United States. Using the stress process framework, Study 2 tested moderation and mediation models of the effects of social support and personal control in the association between discrimination and distress. Results from a series of analyses on 579 respondents suggested that personal control served as a mediator in this relationship and that emotional support exerted a direct distress deterring function. Study 3 investigated sex differences in the associations between social roles, intergenerational family relationship perceptions and distress. Results suggested that positive relationships with an adult son/daughter and with a father, and negative relationships with a mother increased men's distress. Few social roles increased the negative effect that women and men's relationships with an adult son/daughter had on their distress. Multiple roles also increased the negative effect that women's relationships with an adult son/daughter had on their distress. On the other hand, few social roles decreased the distress associated with men's high conflict relationships with mothers. The findings from these three studies suggested that modeling immigrant and ethnic minority mental health requires sensitivity to their immigrant and ethnic minority statuses and to the contexts in which these group members carry out their daily activities.

Is HINARI appropriate for medical students in the developing world?

2012-04-01

The Health InterNetwork Access to Research Initiative (HINARI), which arose in response to medical literature needs in developing countries, gives online access to scientific information to a variety of institutions throughout the world. This is a great resource; however, little research has been performed on the effectiveness and usefulness of HINARI, specifically to medical schools. Our study sought to find out whether the textbooks (e-books) available on HINARI could form a virtual library that would cover the curriculum of a medical school. After categorising and reviewing the medically relevant e-books on HINARI, we found that they were insufficient in providing adequate subject material relevant to medical school curricula from Rwanda, the United Kingdom and the United States. This literature gap could be closed by additional medical textbooks being made available from contributing publishers. An increase of only 14% in HINARI e-book resources would provide material for the entire medical school curriculum. © 2011 Blackwell Publishing Ltd.

We present a high precision deflectometry system (DS) controlled deformable mirror (DM) solution for optical system. Different from wavefront and non-wavefront system, the DS and the DM are set to be an individual integrated DCDM unit and can be installed in one base plate. In the DCDM unit, the DS can directly provide the influence functions and surface shape of the DM to the industrial computer in any adaptive optics system. As an integrated adaptive unit, the DCDM unit could be put into various optical systems to realize aberration compensation. In this paper, the configuration and principle of the DCDM unit is introduced first. Theoretical simulation on the close-loop performance of the DCDM unit is carried out. Finally, a verification experiment is proposed to verify the compensation capability of the DCDM unit.

Prior studies supported an association between intensive care unit (ICU) organizational model or staffing patterns and outcome in critically ill patients. To examine the association of closed versus open models with patient mortality across adult ICUs in King County (WA). Cohort study of patients with acute lung injury (ALI). ICU structure, organization, and patient care practices were assessed using self-administered mail questionnaires completed by the medical director and nurse manager. We defined closed ICUs as units that required patient transfer to or mandatory patient comanagement by an intensivist and open ICUs as those relying on other organizational models. Outcomes were obtained from the King County Lung Injury Project, a population-based cohort of patients with ALI. The main endpoint was hospital mortality. Of 24 eligible ICUs, 13 ICUs were designated closed and 11 open. Complete survey data were available for 23 (96%) ICUs. Higher physician and nurse availability was reported in closed versus open ICUs. A total of 684 of 1,075 (63%) of patients with ALI were cared for in closed ICUs. After adjusting for potential confounders, patients with ALI cared for in closed ICUs had reduced hospital mortality (adjusted odds ratio, 0.68; 95% confidence interval, 0.53, 0.89; P = 0.004). Consultation by a pulmonologist in open ICUs was not associated with improved mortality (adjusted odds ratio, 0.94; 95% confidence interval, 0.74, 1.20; P = 0.62). These findings were robust for varying assumptions about the study population definition. Patients with ALI cared for in a closed-model ICU have reduced mortality. These data support recommendations to implement structured intensive care in the United States.

A liquid level sensor based on a closed field circuit comprises a ring oscillator using a symmetrical array of plate units that creates a displacement current. The displacement current varies as a function of the proximity of a liquid to the plate units. The ring oscillator circuit produces an output signal with a frequency inversely proportional to the presence of a liquid. A continuous liquid level sensing device and a two point sensing device are both proposed sensing arrangements. A second set of plates may be located inside of the probe housing relative to the sensing plate units. The second set of plates prevent any interference between the sensing plate units.

2008-11-01

Lawrence Livermore National Laboratory's E/O program in Fusion Science and Plasma Physics now includes both `pre-service' as well as `in-service' high school science teacher professional development activities. Teachers are instructed and mentored by `master teachers' and LLNL plasma researchers working in concert. The Fusion/Plasma E/O program exploits a unique science education partnership that exists between LLNL's Science Education Program and the UC Davis Edward Teller Education Center. For `in-service' teachers, the Fusion & Astrophysics Teacher Research Academy (TRA) has four levels of workshops that are designed to give in-service high school science teachers experience in promoting and conducting research, most notably in the filed of plasma spectroscopy. Participating teachers in all four TRA levels may earn up to ten units of graduate credit from Cal-State University East Bay, and may apply these units toward a Masters of Science in Education. For `pre-service' teachers, the Science Teacher and Researcher (STAR) program, as a partnership with the California State University System, includes attracting undergraduate science majors to teaching careers by allowing them to pursue professional identities as both a research scientist as well as a science teacher. Participating `pre-service' STAR students are provided research internships at LLNL and work closely with the `in-service' TRA teachers. Results from the continuum `pre-service' to `in-service' science teacher professional development programs will be presented.

Do people with intellectual disability require special human subjects research protections? The interplay of history, ethics, and policy.

PubMed

Feudtner, Chris; Brosco, Jeffrey P

2011-01-01

People with intellectual disability (ID) have a long history of discrimination and stigmatization, and a more recent history of pride and self-advocacy. The early history suggests that people with ID are a vulnerable population and deserve special research protections as do some other groups; the disability rights movement of the late 20th century aligns people with ID more closely with the principle of autonomy that has guided clinical and research ethics for the last 40 years. In examining the history of people with ID and the prevailing framework of human subjects research protections in the United States, we conclude that people with ID do not require special protection in human subjects research. The protections that have already been put in place for all individuals, if conscientiously and effectively implemented, achieve the right balance between safeguarding the interest of human research subjects and empowering individuals who choose to do so to participate in research.

The National Energy Strategy of 1991/1992 provides only the broadest of Outlines for a strategy to ensure a viable nuclear energy generation capability for electrical power. The FY 93 and FY 94 federal defense budgets provide minimum support to maintain a nuclear powered shipbuilding capability within the United States. These two industries are closely related and are vital strategic assets. The United States must implement a more comprehensive strategy to Preserve the core design and production technologies of the nuclear power industry.

The effect of hospital unit layout on nurse walking behavior.

PubMed

Yi, Lu; Seo, Hyun-Bo

2012-01-01

To confirm a new method for the research question, "How do different hospital unit layouts affect nurses' walking behavior and distance?" Concern is renewed regarding nurses' long walking distances because of the trend toward larger patient rooms with family areas inside, resulting in a larger overall unit size. Studies have found unit design characteristics that support nurses' efficient walking, but few have done it in units designed for patient- and family-centered care. To examine the effect of unit design on nurses' walking behavior, the authors propose a new method of observing a specific task. The authors observed nurses during the task of medication administration. Contrary to their hypotheses, results showed: (1) Experienced nurses had more unnecessary stops and longer walking distances than new nurses because of interactions; and (2) nurses in the smaller wing of the unit walked more than those in the larger wing of the same unit. The authors posit that the closeness between the nurses' path to the medication supply room and the central nurses' station affected the frequency of interactions and prompted a deviation from the shortest and most efficient path during medication administration. Observing a specific task to identify the effect of unit layout was effective, determining that overall unit shape or unit layout type might not be a good predictor of nurses' walking behavior; instead the characteristics of the path that connects functional spaces such as patient room and medication area might better predict nurses' walking behavior.

The elk herd that frequents Fossil Butte National Monument, a subset of the West Green River elk population, provides visitors with seasonal opportunities to view an iconic species of the western United States. Throughout the year, these elk range across a variety of private, State, and Federal lands within close proximity to the Monument. These lands are managed differently for various uses which can create challenging wildlife-management issues and influence the herd’s seasonal movements and distribution. Research lead by the USGS investigates some of the factors associated with these seasonal changes.

In a world in which customers are increasingly looking for solutions to their own concerns on how to make a better globalized world, new organizational strategies are emerging to approach the customer in the current third millennium. Servant leadership, which involves putting employees’ needs first and serving the broader society, is emerging as a new strategic mechanism to approach the customer in line with the new social values-driven Marketing 3.0 era. Yet research has ignored the role and the various mechanisms servant leadership might utilize to improve customer service performance of their service units. Spanning 185 hotels located in Spain, a sample of 247 service units –in close contact with customers– was used to investigate whether servant leadership enhances customer service performance through shaping a service climate within the service unit. Results revealed that service climate mediates the positive influence of servant leadership on customer service performance. Managers can use these findings to note the value of leading the service unit in a servant friendly direction, which is better aligned with the new aspirations of customers today. PMID:28559873

The research aimed to enhance Grade 10 Thai students' scientific argumentation in learning about electric field through science, technology, and society (STS) approach. The participants included 45 Grade 10 students who were studying in a school in Nongsonghong, Khon Kaen, Thailand. Methodology regarded interpretive paradigm. The intervention was the force unit which was provided based on Yuenyong (2006) STS approach. Students learned about the STS electric field unit for 4 weeks. The students' scientific argumentation was interpreted based on Toulmin's argument pattern or TAP. The TAP provided six components of argumentation including data, claim, warrants, qualifiers, rebuttals and backing. Tools of interpretation included students' activity sheets, conversation, journal writing, classroom observation and interview. The findings revealed that students held the different pattern of argumentation. Then, they change pattern of argumentation close to the TAP. It indicates that the intervention of STS electric field unit enhance students to develop scientific argumentation. This finding may has implication of further enhancing scientific argumentation in Thailand.

The impact of three recent coal-fired power plant closings on Pittsburgh air quality: A natural experiment.

2017-01-01

Relative to the rest of the United States, the region of southwestern Pennsylvania, including metropolitan Pittsburgh, experiences high ambient concentrations of fine particulate matter (PM 2.5 ), which is known to be associated with adverse respiratory and cardiovascular health impacts. This study evaluates whether the closing of three coal-fired power plants within the southwestern Pennsylvania region resulted in a significant decrease in PM 2.5 concentration. Both PM 2.5 data obtained from EPA ground stations in the study region and aerosol optical depth (AOD) data retrieved from the Moderate Resolution Imaging Spectroradiometer (MODIS) instruments onboard the Terra and Aqua satellites were used to investigate regional air quality from January 2011 through December 2014. The impact of the plant closings on PM 2.5 concentration and AOD was evaluated using a series of generalized additive models. The model results show that monthly fuel consumption of the Elrama plant, which closed in October of 2012, and monthly fuel consumption of both the Mitchell and Hatfield's Ferry plants, which closed in October of 2013, were significant predictors of both PM 2.5 concentration and AOD at EPA ground stations in the study region, after controlling for multiple meteorological factors and long-term, region-wide air quality improvements. The model's power to predict PM 2.5 concentration increased from an adjusted R 2 of 0.61 to 0.68 after excluding data from ground stations with higher uncertainty due to recent increases in unconventional natural gas extraction activities. After preliminary analyses of mean PM 2.5 concentration and AOD showed a downward trend following each power plant shutdown, results from a series of generalized additive models confirmed that the activity of the three plants that closed, measured by monthly fuel consumption, was highly significant in predicting both AOD and PM 2.5 at 12 EPA ground stations; further research on PM 2.5 emissions from unconventional natural gas extraction is needed. With many coal-fired power plants scheduled to close across the United States in the coming years, there is interest in the potential impact on regional PM 2.5 concentrations. In southwestern Pennsylvania, recent coal-fired power plant closings were coupled with a boom in unconventional natural gas extraction. Natural gas is currently seen as an economically viable bridge fuel between coal and renewable energy. This study provides policymakers with more information on the potential ambient concentration changes associated with coal-fired power plant closings as the nation's energy reliance shifts toward natural gas.

Shemanski Aldrich, Rosalie; Cerel, Julie

2009-01-01

Each year there are over 31,000 suicides in the United States, constituting a significant problem in every respect. It is important for research efforts to focus on the communication elements involved in suicide prevention because the messages produced by individuals close to those who have suicidal thoughts have the potential to save a life. The current manuscript presents the theory of planned behavior (TPB) as a foundation to increase understanding of what message content would be most effective to convince an individual to intervene when someone is suicidal. Suicide and suicidal behaviors are briefly reviewed, as is the TPB. Then it is argued how and why TPB can help construct persuasive messages. The authors suggest that TPB guide the content of persuasive messages. Messages created in combination of persuasive theories with TPB are likely to encourage an individual to intervene when someone is suicidal. A key element to suicide prevention is intervention by close others. Use of TPB provides an increased understanding of how to persuade close individuals to intervene when an individual is suicidal.

NASA has been conducting research into reducing sonic boom and changing FAA regulations to allow for supersonic commercial transport over land in the United States. This particular study looks at a plume passing through a shock generated from an aft deck on a nacelle; the aft deck is meant to represent the trailing edge of a wing. NASA Langley Research Center USM3D CFD code results are compared to the experimental data taken at the NASA Glenn Research Center 1-foot by 1-foot Supersonic Wind Tunnel. This study included examining two turbulence models along with different volume sourcing methods for grid generation. The results show that using the k-epsilon turbulence model within USM3D produced shock signatures that closely follow the experimental data at a variety of nozzle pressure ratio settings.

2017-05-01

Because space missions produce pathophysiological alterations such as cardiovascular disorders and bone demineralization which are very common on Earth, biomedical research in space is a frontier that holds important promises not only to counterbalance space-associated disorders in astronauts but also to ameliorate the health of Earth-bound population. Experiments in space are complex to design. Cells must be cultured in closed cell culture systems (from now defined experimental units (EUs)), which are biocompatible, functional, safe to minimize any potential hazard to the crew, and with a high degree of automation. Therefore, to perform experiments in orbit, it is relevant to know how closely culture in the EUs reflects cellular behavior under normal growth conditions. We compared the performances in these units of three different human cell types, which were recently space flown, i.e. bone mesenchymal stem cells, micro- and macrovascular endothelial cells. Endothelial cells are only slightly and transiently affected by culture in the EUs, whereas these devices accelerate mesenchymal stem cell reprogramming toward osteogenic differentiation, in part by increasing the amounts of reactive oxygen species. We conclude that cell culture conditions in the EUs do not exactly mimic what happens in a culture dish and that more efforts are necessary to optimize these devices for biomedical experiments in space. Impact statement Cell cultures represent valuable preclinical models to decipher pathogenic circuitries. This is true also for biomedical research in space. A lot has been learnt about cell adaptation and reaction from the experiments performed on many different cell types flown to space. Obviously, cell culture in space has to meet specific requirements for the safety of the crew and to comply with the unique environmental challenges. For these reasons, specific devices for cell culture in space have been developed. It is important to clarify whether these alternative culture systems impact on cell performances to allow a correct interpretation of the data.

A Gas-Cooled-Reactor Closed-Brayton-Cycle Demonstration with Nuclear Heating

Lipinski, Ronald J.; Wright, Steven A.; Dorsey, Daniel J.; Peters, Curtis D.; Brown, Nicholas; Williamson, Joshua; Jablonski, Jennifer

2005-02-01

A gas-cooled reactor may be coupled directly to turbomachinery to form a closed-Brayton-cycle (CBC) system in which the CBC working fluid serves as the reactor coolant. Such a system has the potential to be a very simple and robust space-reactor power system. Gas-cooled reactors have been built and operated in the past, but very few have been coupled directly to the turbomachinery in this fashion. In this paper we describe the option for testing such a system with a small reactor and turbomachinery at Sandia National Laboratories. Sandia currently operates the Annular Core Research Reactor (ACRR) at steady-state powers up to 4 MW and has an adjacent facility with heavy shielding in which another reactor recently operated. Sandia also has a closed-Brayton-Cycle test bed with a converted commercial turbomachinery unit that is rated for up to 30 kWe of power. It is proposed to construct a small experimental gas-cooled reactor core and attach this via ducting to the CBC turbomachinery for cooling and electricity production. Calculations suggest that such a unit could produce about 20 kWe, which would be a good power level for initial surface power units on the Moon or Mars. The intent of this experiment is to demonstrate the stable start-up and operation of such a system. Of particular interest is the effect of a negative temperature power coefficient as the initially cold Brayton gas passes through the core during startup or power changes. Sandia's dynamic model for such a system would be compared with the performance data. This paper describes the neutronics, heat transfer, and cycle dynamics of this proposed system. Safety and radiation issues are presented. The views expressed in this document are those of the author and do not necessarily reflect agreement by the government.

The method of soil improvement, using the combination of prefabricated vertical drain (PVD) and preloading, was used to accelerate the process of consolidation and the consolidation settlement in the runway of Kualanamu International Airport, which was constructed on the soft soil sediment like silty clay. In this research, the investigated area was the runway of Kualanamu International Airport zone I which had 11 meter-thickness of soft soil. Geotechnic instruments surveyed was settlement plate. Monitoring was done toward the behavior of landfill such as basic soil settlement. The result were compared with the analysis of finite element method of full scale in Mohr-Coulomb model by verifying the vertical drain of asymmetric unit cell and equivalent plane strain unit cell condition. The results of the research showed that there were an interesting behavior between the data in field observation and finite element of Mohr-Coulomb model. It was also found that the result of soil settlement of finite element method of Mohr-Coulomb model was closed to the result of settlement plate monitoring.

Neurogenetics is an emerging discipline in Peru that links basic research with clinical practice. The Neurogenetics Research Center located in Lima, Peru is the only unit dedicated to the specialized care of neurogenetic diseases in the country. From the beginning, neurogenetics research has been closely linked to the study of Huntington’s Disease (HD), from the PCR genotyping of the HTT gene, to the current haplogroup studies in HD. Research in other monogenic diseases led to the implementation of alternative methodologies for the genotyping of Fragile X and Myotonic Dystrophy Type 1. Both, national and international collaborative efforts have facilitated the discovery of new genetic variants in complex multigenic diseases such as Parkinson’s disease and Alzheimer’s disease. Additionally, multidisciplinary education and mentoring have allowed for the training of new neurogenetics specialists, supporting the sustained growth of the discipline in the country. The promotion of research in Peru has spurred the growth of neurogenetics research, although limitations in infrastructure, technology, and education remain a challenge for the further growth of research in this field.

The Crop Growth Research Chamber (CGRC) has been defined by CELSS principle investigators and science advisory panels as a necessary ground-based tool in the development of a regenerative life support system. The focus of CGRC research will be on the biomass production component of the CELSS system. The ground-based Crop Growth Research Chamber is for the study of plant growth and development under stringently controlled environments isolated from the external environment. The chamber has importance in three areas of CELSS activities: (1) crop research; (2) system control and integration, and (3) flight hardware design and experimentation. The laboratory size of the CGRC will be small enough to allow duplication of the unit, the conducting of controlled experiments, and replication of experiments, but large enough to provide information representative of larger plant communities. Experiments will focus on plant growth in a wide variety of environments and the effects of those environments on plant production of food, water, oxygen, toxins, and microbes. To study these effects in a closed system, tight control of the environment is necessary.

The rise of pathophysiologic research in the United States: the role of two Harvard hospitals.

PubMed

Tishler, Peter V

2013-01-01

Pathophysiologic research, the major approach to understanding and treating disease, was created in the 20th century, and two Harvard-affiliated hospitals, the Peter Bent Brigham Hospital and Boston City Hospital, played a key role in its development. After the Flexner Report of 1910, medical students were assigned clinical clerkships in teaching hospitals. Rockefeller-trained Francis Weld Peabody, who was committed to investigative, pathophysiologic research, was a critical leader in these efforts. At the Brigham, Harvard medical students observed patients closely and asked provocative questions about their diseases. Additionally, physicians returned from World War I with questions concerning the pathophysiology of wartime injuries. At the Boston City Hospital's new Thorndike Memorial Laboratory, Peabody fostered investigative question-based research by physicians. These physicians expanded pathophysiologic investigation from the 1920s. Post-war, Watson and Crick's formulation of the structure of DNA led shortly to modern molecular biology and new research approaches that are being furthered at the Boston Hospitals.

The University of Kansas Center for Research, Inc. was commissioned by the Kansas Energy Office and the US Department of Energy to conduct a review of certain oil shales in Kansas. The purpose of the study focused on making an inventory and assessing those oil shales in close stratigraphic proximity to coal beds close to the surface and containing significant reserves. The idea was to assess the feasibility of using coal as an economic window to aid in making oil shales economically recoverable. Based on this as a criterion and the work of Runnels, et al., (Runnels, R.T., Kulstead, R.O.,more » McDuffee, C. and Schleicher, J.A., 1952, Oil Shale in Kansas, Kansas Geological Survey Bulletin, No. 96, Part 3.) five eastern Kansas black shale units were selected for study and their areal distribution mapped. The volume of recoverable oil shale in each unit was calculated and translated to reserves. The report concludes that in all probability, extraction of oil shale for shale oil is not feasible at this time due to the cost of extraction, transportation and processing. The report recommends that additional studies be undertaken to provide a more comprehensive and detailed assessment of Kansas oil shales as a potential fuel resource. 49 references, 4 tables.« less

Design parameters for toroidal and bobbin magnetics. [conversion from English to metric units

NASA Technical Reports Server (NTRS)

Mclyman, W. T.

1974-01-01

The adoption by NASA of the metric system for dimensioning to replace long-used English units imposes a requirement on the U.S. transformer designer to convert from the familiar units to the less familiar metric equivalents. Material is presented to assist in that transition in the field of transformer design and fabrication. The conversion data makes it possible for the designer to obtain a fast and close approximation of significant parameters such as size, weight, and temperature rise. Nomographs are included to provide a close approximation for breadboarding purposes. For greater convenience, derivations of some of the parameters are also presented.

Where Planets Take up Residence

NASA Technical Reports Server (NTRS)

2007-01-01

This diagram illustrates that mature planetary systems like our own might be more common around twin, or binary, stars that are either really close together, or really far apart.

NASA's Spitzer Space Telescope observed that debris disks, which are signposts of mature planetary systems, are more abundant around the tightest and widest of binary stars it studied. Specifically, the infrared telescope found significantly more debris disks around binary stars that are 0 to 3 astronomical units apart (top panel) and 50 to 500 astronomical units apart (bottom panel) than binary stars that are 3 to 50 astronomical units apart (middle panel). An astronomical unit is the distance between Earth and the sun.

In other words, if two stars are as far apart from each other as the sun is from Jupiter (5 astronomical units) or Pluto (40 astronomical units), they would be unlikely to host a family of planetary bodies.

The Spitzer data also revealed that debris disks circle all the way around both members of a close-knit binary (top panel), but only a single member of a wide duo (bottom panel). This could explain why the intermediately spaced binary systems (middle panel) can be inhospitable to planetary disks: they are too far apart to support one big disk around both stars, and they are too close together to have enough room for a disk around just one star.

Drosophila suzukii Matsumura (spotted wing drosophila) has recently become a serious pest of a wide variety of fruit crops in the United States as well as in Europe, leading to substantial yearly crop losses. To enable basic and applied research of this important pest, we sequenced the D. suzukii genome to obtain a high-quality reference sequence. Here, we discuss the basic properties of the genome and transcriptome and describe patterns of genome evolution in D. suzukii and its close relatives. Our analyses and genome annotations are presented in a web portal, SpottedWingFlyBase, to facilitate public access. PMID:24142924

[Mobile Health Units: An Analysis of Concepts and Implementation Requirements in Rural Regions.

PubMed

Hämel, K; Kutzner, J; Vorderwülbecke, J

2017-12-01

Access to health services in rural regions represents a challenge. The development of care models that respond to health service shortages and pay particular attention to the increasing health care needs of the elderly is an important concern. A model that has been implemented in other countries is that of mobile health units. But until now, there is no overview of their possible objectives, functions and implementation requirements. This paper is based on a literature analysis and an internet research on mobile health units in rural regions. Mobile health units aim to avoid regional undersupply and address particularly vulnerable population groups. In the literature, mobile health units are described with a focus on specific illnesses, as well as those that provide comprehensive, partly multi-professional primary care that is close to patients' homes. The implementation of mobile health units is demanding; the key challenges are (a) alignment to the needs of the regional population, (b) user-oriented access and promotion of awareness and acceptance of mobile health units by the local population, and (c) network building within existing care structures to ensure continuity of care for patients. To fulfill these requirements, a community-oriented program development and implementation is important. Mobile health units could represent an interesting model for the provision of health care in rural regions in Germany. International experiences are an important starting point and should be taken into account for the further development of models in Germany. © Georg Thieme Verlag KG Stuttgart · New York.

The Relationships of Intergroup Ideologies to Ethnic Prejudice: A Meta-Analysis.

PubMed

Whitley, Bernard E; Webster, Gregory D

2018-04-01

This meta-analysis summarizes the results of research on the relationships of majority group members' endorsement of assimilation, colorblindness, multiculturalism, and the relative relationships of colorblindness and multiculturalism to ethnic prejudice. Random effects analyses found that assimilation was positively related to explicit prejudice ( g. = 0.80), multiculturalism was negatively related to both explicit ( g. = -0.26) and implicit prejudice ( g. = -0.19), and colorblindness was negatively related to explicit prejudice ( g. = -0.07). Multiculturalism was more closely associated with low prejudice than colorblindness ( g. = 0.15). Effect sizes varied as a function of methodology (experimental vs. correlational), country in which research was conducted (United States vs. other countries), and, in experimental studies of multiculturalism, type of prime used (abstract vs. concrete). Discussion points include methodological issues, groups used as targets of prejudice, national diversity norms, additional issues raised in the studies reviewed, and directions for future research.

This African Journal of Disability supplement focuses on papers presented at the third AfriNEAD Symposium in 2011. In this closing editorial, we want to give an overview of the rationale and major modes of operation of the African Network for Evidence-to-Action on Disability (AfriNEAD) with special focus on recommendations made at the 2011 AfriNEAD Symposium. AfriNEAD is guided and informed by the United Nations Convention on the Rights of Persons with Disabilities (UNCRPD) for its research themes. The issues that emerged from AfriNEAD 2011 ranged from children and youth with disabilities; education across the lifespan; economic empowerment; the development process in Africa; health, HIV and AIDS and community-based rehabilitation; holistic wellness; to research evidence and utilisation. Disability-related stigma, the value of emancipatory research and the need to recognise a broader scope of valid methodologies were also highlighted.

Can Standards Increase Consumer Welfare? Evidence from a Change in Clothes Washer

DOE Office of Scientific and Technical Information (OSTI.GOV)

Chen, Xiaomei; Roberts, Michael J.; Yang, Hung-Chia

We study prices and sales of individual clothes washer models before, during and after a 2007 standard that banned manufacture (but not sale) of low-e ciency units and increased the threshold for Energy Star certi cation. While quantities sold of washer models banned from manufacture decreased sharply, prices for banned models increased only modestly. At the same time, sales of higher-e ciency units rose markedly while prices for high-e ciency units declined. On average, washer e ciency increased but prices changed little. A simple welfare analysis indicates that consumer welfare loss from banned washers was far outweighed by gains frommore » lower-priced high-e ciency units. While a full cost-bene t analysis is not feasible with the available data, we estimate a lower-bound gain in consumer surplus equal to 6-16 percent of total sales. This result may accord with earlier theoretical research that shows quality standards can increase welfare in monopolistically competitive industries that possess increasing returns to scale (Ronnen, 1991). Thus, if energy e ciency is a close proxy for quality, energy e ciency standards may increase competition, market e ciency and welfare.« less

Identification of subsurface microorganisms at Yucca Mountain; Second quarterly report, October 1, 1993--December 31, 1993

Stetzenbach, L.D.

1993-12-31

The primary effort of this past quarter was to develop a procedure where accumulated data files could be evaluated to determine the naming consistency and inter-relationships of the various species which have been identified by the Microbial Identification System (MIDI) system. This involved a series of steps, including the clustering of similarly named organisms in a dendrogram format to determine how closely similarly named isolates are related. The experience of other researchers using the MIDI system has shown that clusters which are joined at a Euclidian distance of 10 or less belong to the same species. Strains which are verymore » similar cluster at less than 6 Euclidian units and clusters below two units have nearly identical fatty acid patterns. When the dendrograms derived from the springs were scrutinized, some organisms were found which did not match the pattern of their named group. Then a decision was made whether to rename the isolates and exclude them from the group or redefine the group. This decision was assisted by plotting the principal components derived from an analysis of the fatty acid composition of members of the genus. Each species can be examined by the same procedure to determine group homogeneity. In these 2-dimensional plots members of the same species are roughly bounded by a box of 100 squared units while closely related strains are grouped more tightly together. The 2-dimensional plot of isolates of Micrococcus luteus demonstrates the presence of three identifiable sub-species.« less

De Steur, Hans; Mehta, Saurabh; Gellynck, Xavier; Finkelstein, Julia L

2017-04-01

Genetic engineering has been successfully applied to increase micronutrient content in staple crops. Nutrition evidence is key to ensure scale-up and successful implementation. Unlike conventional plant breeding efforts, research on the efficacy or effectiveness of GM biofortified crops on nutritional status in human populations is lacking. This review reports on the potential role of GM biofortified crops in closing the micronutrient gap - increasing the dietary intake of micronutrients in human populations. To date, one clinical trial in the United States reported a high bio-conversion rate of β-carotene in Golden Rice, and potential effects of GM biofortified crop consumption on dietary intake and nutritional outcomes are promising. However, further research needs to confirm the ex ante assessments in target regions. Copyright © 2017. Published by Elsevier Ltd.

Conceptual design studies and experiments related to cavity exhaust systems for nuclear light bulb configurations

1972-01-01

Investigations of various phases of gaseous nuclear rocket technology have been conducted. The principal research efforts have recently been directed toward the closed-cycle, vortex-stabilized nuclear light bulb engine and toward a small-scale fissioning uranium plasma experiment that could be conducted in the Los Alamos Scientific Laboratory's Nuclear Furnace. The engine concept is based on the transfer of energy by thermal radiation from gaseous fissioning uranium, through a transparent wall, to hydrogen propellant. The reference engine configuration is comprised of seven unit cavities, each having its own fuel transparent wall and propellant duct. The basic design of the engine is described. Subsequent studies performed to supplement and investigate the basic design are reported. Summaries of other nuclear light bulb research programs are included.

The primary emphasis of this research was to investigate the foundations of phthalate (PAEs) pollutant source researches and then firstly confirmed the concept of the coefficient of volatile strength, namely phthalate total content in per unit mass and unit surface area of pollutant sources. Through surveying and evaluating the coefficient of volatile strength of PAEs from typical plastic products, this research carried out reasonable classification of PAEs pollutant sources into three categories and then investigated the relationship amongst the coefficient of volatile strength as well as other environmental factors and the concentration level of total PAEs in indoor air measured in environment chambers. Research obtained phthalate concentration results under different temperature, humidity, the coefficient of volatile strength and the closed time through the chamber experiment. In addition, this study further explored the correlation and ratio of influencing factors that affect the concentration level of total PAEs in environment chambers, including environmental factors, the coefficient of volatile strengths of PAEs and contents of total PAEs in plastic products. The research created an improved database system of phthalate the coefficient of volatile strengths of each type of plastic goods, and tentatively revealed that the volatile patterns of PAEs from different typical plastic goods, finally confirmed that the coefficient of volatile strengths of PAEs is a major factor that affects the indoor air total PAEs concentration, which laid a solid foundation for further establishing the volatile equation of PAEs from plastic products.

The Sarcoma Policy Checklist was created by a multidisciplinary expert group to provide policymakers with priority areas to improve care for sarcoma patients. This paper draws on this research, by looking more closely at how France, Germany, Italy, Spain, Sweden and the United Kingdom are addressing each of these priority areas. It aims to highlight key gaps in research, policy and practice, as well as ongoing initiatives that may impact the future care of sarcoma patients in different European countries. A pragmatic review of the published and web-based literature was undertaken. Telephone interviews were conducted in each country with clinical and patient experts to substantiate findings. Research findings were discussed within the expert group and developed into five core policy recommendations. The five identified priority areas were: the development of designated and accredited centres of reference; more professional training; multidisciplinary care; greater incentives for research and innovation; and more rapid access to effective treatments. Most of the countries studied have ongoing initiatives addressing many of these priorities; however, many are in early stages of development, or require additional funding and resources. Gaps in access to quality care are particularly concerning in many of Europe's lower-resourced countries. Equitable access to information, clinical trials, innovative treatments and quality specialist care should be available to all sarcoma patients. Achieving this across Europe will require close collaboration between all stakeholders at both the national and European level.

In-home air filtration for improving cardiovascular health: Lessons from a CBPR study in public housing

2013-01-01

Background Particulate air pollution, including from motor vehicles, is associated with cardiovascular disease. Objectives To describe lessons learned from installing air filtration units in public housing apartments next to a major highway. Methods We reviewed experience with recruitment, retention and acceptance of the air filtration units. Results Recruitment and retention have been challenging, but similar to other studies in public housing. Equipment noise and overheated apartments during hot weather have been notable complaints from participants. In addition, we found that families with members with Alzheimer’s or mental disability were less able to tolerate the equipment. Conclusions For this research the primary lesson is that working closely with each participant is important. A future public health program would need to address issues of noise and heat to make the intervention more acceptable to residents. PMID:23543021

Propulsion simulation test technique for V/STOL configurations

1983-01-01

Ames Research Center is developing the technology for turbine-powered jet engine simulators so that airframe/propulsion system interactions on V/STOL fighter aircraft and other highly integrated configurations can be studied. This paper describes the status of the compact multimission aircraft propulsion simulator (CMAPS) technology. Three CMAPS units have accumulated a total of 340 hr during approximately 1-1/2 yr of static and wind-tunnel testing. A wind-tunnel test of a twin-engine CMAPS-equipped close-coupled canard-wing V/STOL model configuration with nonaxisymmetric nozzles was recently completed. During this test approximately 140 total hours were logged on two CMAPS units, indicating that the rotating machinery is reliable and that the CMAPS and associated control system provide a usable test tool. However, additional development is required to correct a drive manifold O-ring problem that limits the engine-pressure-ratio (EPR) to approximately 3.5.

Estimating the extent of impervious surfaces and turf grass across large regions

Claggett, Peter; Irani, Frederick M.; Thompson, Renee L.

2013-01-01

The ability of researchers to accurately assess the extent of impervious and pervious developed surfaces, e.g., turf grass, using land-cover data derived from Landsat satellite imagery in the Chesapeake Bay watershed is limited due to the resolution of the data and systematic discrepancies between developed land-cover classes, surface mines, forests, and farmlands. Estimates of impervious surface and turf grass area in the Mid-Atlantic, United States that were based on 2006 Landsat-derived land-cover data were substantially lower than estimates based on more authoritative and independent sources. New estimates of impervious surfaces and turf grass area derived using land-cover data combined with ancillary information on roads, housing units, surface mines, and sampled estimates of road width and residential impervious area were up to 57 and 45% higher than estimates based strictly on land-cover data. These new estimates closely approximate estimates derived from authoritative and independent sources in developed counties.

Accumulation and subsequent compression of carbon dioxide that is removed from the space cabin are two important processes involved in a closed-loop air revitalization scheme of the International Space Station (ISS). The 4-Bed Molecular Sieve (4BMS) of ISS currently operates in an open loop mode without a compressor. The Sabatier Engineering Development Unit (EDU) processes waste CO2 to provide water to the crew. This paper reports the integrated 4BMS, air-cooled Temperature Swing Adsorption Compressor (TSAC), and Sabatier EDU testing. The TSAC prototype was developed at NASA Ames Research Center (ARC). The 4BMS was modified to a functionally flight-like condition at NASA Marshall Space Flight Center (MSFC). Testing was conducted at MSFC. The paper provides details of the TSAC operation at various CO2 loadings and corresponding performance of the 4BMS and Sabatier.

Mind over matter? The role of individual perceptions in understanding the social ecology of housing environments for individuals with psychiatric disabilities.

PubMed

Townley, Greg; Kloos, Bret

2014-12-01

There is a disagreement in place-based research regarding whether objective indicators or individual perceptions of environments are better predictors of well-being. This study assessed environmental influences on well-being for 373 individuals with psychiatric disabilities living independently in 66 neighborhoods in the southeastern United States. Three questions were examined utilizing random effects models: (1) How much variance in personal and neighborhood well-being can be explained by neighborhood membership? (2) What is the relationship between participant perceptions of neighborhood quality and researcher ratings of neighborhood quality? and (3) What is the relative influence of individual perceptions, perceptions aggregated by neighborhood, and researcher ratings of neighborhood quality in predicting personal and neighborhood well-being? Results indicate that individual perceptions of neighborhood quality were more closely related to well-being than either aggregated perceptions or researcher ratings. Thus, participants' perceptions of their neighborhoods were more important indicators of their well-being than objective ratings made by researchers. Findings have implications for measurement approaches and intervention design in placed-based research.

Sound Environments Surrounding Preterm Infants Within an Occupied Closed Incubator.

PubMed

Shimizu, Aya; Matsuo, Hiroya

2016-01-01

Preterm infants often exhibit functional disorders due to the stressful environment in the neonatal intensive care unit (NICU). The sound pressure level (SPL) in the NICU is often much higher than the levels recommended by the American Academy of Pediatrics. Our study aims to describe the SPL and sound frequency levels surrounding preterm infants within closed incubators that utilize high frequency oscillation (HFO) or nasal directional positive airway pressure (nasal-DPAP) respiratory settings. This is a descriptive research study of eight preterm infants (corrected age<33 weeks) exposed to the equipment when placed in an incubator. The actual noise levels were observed and the results were compared to the recommendations made by neonatal experts. Increased noise levels, which have reported to affect neonates' ability to self-regulate, could increase the risk of developing attention deficit disorder, and may result in tachycardia, bradycardia, increased intracranial pressure, and hypoxia. The care provider should closely assess for adverse effects of higher sound levels generated by different modes of respiratory support and take measures to ensure that preterm infants are protected from exposure to noise exceeding the optimal safe levels.

2017-01-01

Herbal and dietary supplements (HDS) are used increasingly both in the United States and worldwide, and HDS-induced liver injury in the United States has increased proportionally. Current challenges in the diagnosis and management of HDS-induced liver injury were the focus of a 2-day research symposium sponsored by the American Association for the Study of Liver Disease and the National Institutes of Health. HDS-induced liver injury now accounts for 20% of cases of hepatotoxicity in the United States based on research data. The major implicated agents include anabolic steroids, green tea extract, and multi-ingredient nutritional supplements. Anabolic steroids marketed as bodybuilding supplements typically induce a prolonged cholestatic but ultimately self-limiting liver injury that has a distinctive serum biochemical as well as histological phenotype. Green tea extract and many other products, in contrast, tend to cause an acute hepatitis-like injury. Currently, however, the majority of cases of HDS-associated liver injury are due to multi-ingredient nutritional supplements, and the component responsible for the toxicity is usually unknown or can only be suspected. HDS-induced liver injury presents many clinical and research challenges in diagnosis, identification of the responsible constituents, treatment, and prevention. Also important are improvements in regulatory oversight of nonprescription products to guarantee their constituents and ensure purity and safety. The confident identification of injurious ingredients within HDS will require strategic alignments among clinicians, chemists, and toxicologists. The ultimate goal should be to prohibit or more closely regulate potentially injurious ingredients and thus promote public safety.

One of the more serious adverse outcomes of military airborne operations is closed-head injuries. This investigation examined risk factors for closed-head injuries in an Army airborne infantry unit. Closed-head injuries were defined as energy exchanges in which the head contacted the ground or an object and the soldier sought medical care for external trauma, headache, loss of consciousness, or altered mental state. Injury data were obtained by investigators in the drop zone and diagnoses were confirmed by a physician. Operational data on potential injury risk factors were obtained from routine reports published by the infantry unit. Weather data were obtained using a pocket weather tracker. There were 96,132 jumps resulting in 310 closed-head injuries for a crude incidence of 3.22/1000 jumps. In 98% of known cases the injury was associated with parachute landings. Multivariate logistic regression revealed that independent risk factors for closed-head injuries included night jumps, combat loads, higher wind speeds, higher temperatures, enlisted rank, and entanglements. This study identifies the current incidence and extrinsic risk factors for closed-head injuries during military airborne operations. Although it is necessary to conduct airborne training under realistic conditions, trainers and commanders should be aware of these risks and plan airborne operations accordingly.

Performance of a High-Fidelity 4kW-Class Engineering Model PPU and Integration with HiVHAc System

NASA Technical Reports Server (NTRS)

Pinero, Luis R.; Kamhawi, Hani; Shilo, Vlad

2016-01-01

The High Voltage Hall Accelerator (HiVHAc) propulsion system consists of a thruster, power processing unit (PPU), and propellant feed system. An engineering model PPU was developed by Colorado Power Electronics, Inc. funded by NASA's Small Business Innovative Research Program. This PPU uses an innovative 3-phase resonant converter to deliver 4 kW of discharge power over a wide range of input and output voltage conditions. The PPU includes a digital control interface unit that automatically controls the PPU and a xenon flow control module (XFCM). It interfaces with a control computer to receive highlevel commands and relay telemetry through a MIL-STD-1553B interface. The EM PPU was thoroughly tested at GRC for functionality and performance at temperature limits and demonstrated total efficiencies a high as 95 percent. Integrated testing of the unit was performed with the HiVHAc thruster and the XFCM to demonstrate closed-loop control of discharge current with anode flow. Initiation of the main discharge and power throttling were also successfully demonstrated and discharge oscillations were characterized.

Given their clinical, research, and administrative purposes, scores on the Acute Physiology and Chronic Health Evaluation (APACHE) II should be reliable, whether calculated by health care personnel or a clinical information system. To determine reliability of APACHE II scores calculated by a clinical information system and by health care personnel before and after a multifaceted quality improvement intervention. APACHE II scores of 37 consecutive patients admitted to a closed, 15-bed, university-affiliated intensive care unit were collected by a research coordinator, a database clerk, and a clinical information system. After a quality improvement intervention focused on health care personnel and the clinical information system, the same methods were used to collect data on 32 consecutive patients. The research coordinator and the clerk did not know each other's scores or the information system's score. The data analyst did not know the source of the scores until analysis was complete. APACHE II scores obtained by the clerk and the research coordinator were highly reliable (intraclass correlation coefficient, 0.88 before vs 0.80 after intervention; P = .25). No significant changes were detected after the intervention; however, compared with scores of the research coordinator, the overall reliability of APACHE II scores calculated by the clinical information system improved (intraclass correlation coefficient, 0.24 before intervention vs 0.91 after intervention, P < .001). After completion of a quality improvement intervention, health care personnel and a computerized clinical information system calculated sufficiently reliable APACHE II scores for clinical, research, and administrative purposes.

Constraining the Type Ia Supernova Progenitor: The Search for Hydrogen in Nebular Spectra

NASA Astrophysics Data System (ADS)

Leonard, Douglas C.

2007-12-01

Despite intense scrutiny, the progenitor system(s) that gives rise to Type Ia supernovae remains unknown. The favored theory invokes a carbon-oxygen white dwarf accreting hydrogen-rich material from a close companion until a thermonuclear runaway ensues that incinerates the white dwarf. However, simulations resulting from this single-degenerate, binary channel demand the presence of low-velocity Hα emission in spectra taken during the late nebular phase, since a portion of the companion's envelope becomes entrained in the ejecta. This hydrogen has never been detected, but has only rarely been sought. Here we present results from a campaign to obtain deep, nebular-phase spectroscopy of nearby Type Ia supernovae, and include multiepoch observations of two events: SN 2005am (slightly subluminous) and SN 2005cf (normally bright). No Hα emission is detected in the spectra of either object. An upper limit of 0.01 Msolar of solar abundance material in the ejecta is established from the models of Mattila et al., which, when coupled with the mass-stripping simulations of Marietta et al. and Meng et al., effectively rules out progenitor systems for these supernovae with secondaries close enough to the white dwarf to be experiencing Roche lobe overflow at the time of explosion. Alternative explanations for the absence of Hα emission, along with suggestions for future investigations necessary to confidently exclude them as possibilities, are critically evaluated. Some of the data presented herein were obtained at the W. M. Keck Observatory, which is operated as a scientific partnership among the California Institute of Technology, the University of California, and the National Aeronautics and Space Administration. The Observatory was made possible by the generous financial support of the W. M. Keck Foundation. Additional observations were obtained at the Gemini Observatory, which is operated by the Association of Universities for Research in Astronomy, Inc., under a cooperative agreement with the NSF on behalf of the Gemini partnership: the National Science Foundation (United States), the Particle Physics and Astronomy Research Council (United Kingdom), the National Research Council (Canada), CONICYT (Chile), the Australian Research Council (Australia), CNPq (Brazil), and CONICET (Argentina).

Impact of an aseptic procedure for breaking the integrity of the urinary drainage system on the development of catheter-associated urinary tract infections in the intensive care unit.

PubMed

Powers, Jan

2016-12-01

Catheter associated urinary tract infections (CAUTI) are a common complication in the hospital, especially in intensive care units (ICU). These infections are directly linked to the use of an indwelling urinary catheter. One commonly identified factor related to the development of CAUTI has been thought to be violating the integrity of the closed drainage system. However, a paucity of research exists to support or refute this practice. The primary purpose of this observational study was to assess if there is a relationship between CAUTI incidence and breaking the closed drainage system using an aseptic procedure. A process improvement effort was developed to ensure an aseptic technique was utilised when there was a need to break the integrity of the urinary drainage system. Because this was a new practice and not supported by the Centres for Disease Control (CDC) recommendations, this change in practice was evaluated as an observational study. In an eight month period there were 53 documented breaks in the urinary drainage system. There were 28 total cases of CAUTI overall during this same time period. Only four patients with a system break developed a CAUTI (7.5%). In almost 93% of the patients where aseptic technique was used for breaks in the drainage system, there was no occurrence of CAUTI. A follow-up evaluation was performed after a year of this practice in three adult ICUs. During this three month evaluation period, there were 47 documented cases of breaking this system using aseptic technique. Of the patients who had a documented break in their drainage system, none developed subsequent CAUTIs. One commonly identified factor related to the development of CAUTI has been thought to be violating the integrity of the closed drainage system. However, a paucity of research exists to support or refute this practice. This observational study found that utilising an aseptic technique to break the integrity system did not result in an associated increase in CAUTI. Copyright © 2016 Elsevier Ltd.

We propose a novel risk stratified followup protocol for use after urethroplasty and explore potential cost savings. Decision analysis was performed comparing a symptom based, risk stratified protocol for patients undergoing excision and primary anastomosis urethroplasty vs a standard regimen of close followup for urethroplasty. Model assumptions included that excision and primary anastomosis has a 94% success rate, 11% of patients with successful urethroplasty had persistent lower urinary tract symptoms requiring cystoscopic evaluation, patients in whom treatment failed undergo urethrotomy and patients with recurrence on symptom based surveillance have a delayed diagnosis requiring suprapubic tube drainage. The Nationwide Inpatient Sample from 2010 was queried to identify the number of urethroplasties performed per year in the United States. Costs were obtained based on Medicare reimbursement rates. The 5-year cost of a symptom based, risk stratified followup protocol is $430 per patient vs $2,827 per patient using standard close followup practice. An estimated 7,761 urethroplasties were performed in the United States in 2010. Assuming that 60% were excision and primary anastomosis, and with more than 5 years of followup, the risk stratified protocol was projected to yield an estimated savings of $11,165,130. Sensitivity analysis showed that the symptom based, risk stratified followup protocol was far more cost-effective than standard close followup in all settings. Less than 1% of patients would be expected to have an asymptomatic recurrence using the risk stratified followup protocol. A risk stratified, symptom based approach to urethroplasty followup would produce a significant reduction in health care costs while decreasing unnecessary followup visits, invasive testing and radiation exposure.

The {open_quotes}Golfe du Lion{close_quotes} Pleistocene shelf deposits are used as modern analogues of ancient deltaic and shallow water siliciclastic deposits. At least 6 cyclic superimposed sedimentary packages constituting a seaward thickening wedge are documented, including major progradational clinoforms units bounded by regional unconformities, with their updip terminations. Seismic correlations and geometry models, together with age dating and facies analysis of the uppermost units have been used at regional scale. They allowed to differentiate allocyclic from autocyclic events, to improve our knowledge of the nature of tectonic control on architecture, and to rely the different seismic units, inside the packages, tomore » the environmental changes from interglacial highstand to glacial lowstand in 4 to 5th order cycles. An alternative model of {open_quotes}forced regression{close_quotes} during sea level lowstand was documented and validated. The different illustrated sedimentary units, related to specific parts of the relative sea level curve along a short duration/high amplitude cycle, are: (i) the {open_quotes}forced regression{close_quotes} deposits (ii) the late lowstand massive sands onto the outer shelf (iii) the early transgressive backstepping (?) beach sands, (iii) the late transgressive backslapping parasequences. The sand content inferred from the seismic facies, comforted with the uppermost units facies from data cores, is in agreement with this model.« less

2010-01-01

This study describes a large database of closed medical professional liability (MPL) claims involving family physicians in the United States. The purpose of this report is to provide information for practicing family physicians that will be useful in improving the quality of care, thereby reducing the incidence of patient injury and the consequent frequency of MPL claims. The Physician Insurers Association of America (PIAA) established a registry of closed MPL claims in 1985. This registry contains data describing 239,756 closed claims in the United States through 2008. The registry is maintained for educational programs that are designed to improve quality of care and reduce patient injury MPL claims. We summarized this closed claims database. Of 239,756 closed claims, 27,556 (11.5%) involved family physicians. Of these 27,556 closed claims, 8797 (31.9%) resulted in a payment, and the average payment was $164,107. In the entire registry, 29.5% of closed claims were paid, and the average payment was $209,156. The most common allegation among family medicine closed claims was diagnostic error, and the most prevalent diagnosis was acute myocardial infarction, which represented 24.1% of closed claims with diagnostic errors. Diagnostic errors related to patients with breast cancer represented the next most common condition, accounting for 21.3% of closed claims with diagnostic errors. MPL issues are common and are important to all practicing family physicians. Knowledge of the details of liability claims should assist practicing family physicians in improving quality of care, reducing patient injury, and reducing the incidence of MPL claims.

Ackeret, J.; Keller, D. C.

1942-01-01

Hot-air engines with dynamic compressors and turbines offer new prospects of success through utilization of units of high efficiencies and through the employment of modern materials of great strength at high temperature. Particular consideration is given to an aerodynamic prime mover operating on a closed circuit and heated externally. Increase of the pressure level of the circulating air permits a great increase of limit load of the unit. This also affords a possibility of regulation for which the internal efficiency of the unit changes but slightly. The effect of pressure and temperature losses is investigated. A general discussion is given of the experimental installation operating at the Escher Wyss plant in Zurich for a considerable time at high temperatures.

2012-01-01

This article describes a review of the Biomedical Research Units (BRU) scheme, undertaken for the Department of Health. This review was a perceptions audit of senior executives involved in the scheme, and explored what impact they felt the scheme is having on the translational research landscape. More specifically, we investigated whether and how institutional relationships between NHS and academic partners, industry and other health research system players are changing because of the scheme; how the scheme is helping build critical mass in specific priority disease areas; and the effects of any changes on efforts to deliver the broader goals set out in Best Research for Best Health. The views presented are those of study informants only. The information obtained through our interviews suggests that the BRU scheme is significantly helping shape the health research system to pursue translational research and innovation, with the clear goal of realising patient benefit. The BRUs are already contributing to observable changes in institutional relationships between the NHS and academic partners: trusts and medical schools are collaborating more closely than in the past, have signed up to the same vision of translational research from bench to bedside, and are managing and governing targeted research resources more professionally and transparently than in the past. There is also a stronger emphasis on engaging industry and more strategic thinking about strengthening regional and national collaboration with other hospital trusts, PCTs, research organisations, networks and development agencies. The scheme is also transforming capacity building in the health research system. This includes (i) developing and modernising facilities and equipment for translation; (ii) building a critical mass of human resources through recruitment and training, as well as improving retention of existing expertise; and (iii) helping ensure a steady flow of funds needed to sustain research activity and accelerate movement through the innovation pipeline. A number of centres are also trying to recreate the BRU model in new disease areas, with their own resources.

This report presents the results of Run 262 performed at the Advanced Coal Liquefaction R&D Facility in Wilsonville, Alabama. The run started on July 10, 1991 and continued until September 30, 1991, operating in the Close-Coupled Integrated Two-Stage Liquefaction mode processing Black Thunder Mine subbituminous coal (Wyodak-Anderson seam from Wyoming Powder River Basin). A dispersed molybdenum catalyst was evaluated for its performance. The effect of the dispersed catalyst on eliminating solids buildup was also evaluated. Half volume reactors were used with supported Criterion 324 1/16`` catalyst in the second stage at a catalyst replacement rate of 3 lb/ton of MFmore » coal. The hybrid dispersed plus supported catalyst system was tested for the effect of space velocity, second stage temperature, and molybdenum concentration. The supported catalyst was removed from the second stage for one test period to see the performance of slurry reactors. Iron oxide was used as slurry catalyst at a rate of 2 wt % MF coal throughout the run (dimethyl disulfide (DMDS) was used as the sulfiding agent). The close-coupled reactor unit was on-stream for 1271.2 hours for an on-stream factor of 89.8% and the ROSE-SR unit was on-feed for 1101.6 hours for an on-stream factor of 90.3% for the entire run.« less

Research and Technology Activities Supporting Closed-Brayton-Cycle Power Conversion System Development

NASA Technical Reports Server (NTRS)

Barrett, Michael J.

2004-01-01

The elements of Brayton technology development emphasize power conversion system risk mitigation. Risk mitigation is achieved by demonstrating system integration feasibility, subsystem/component life capability (particularly in the context of material creep) and overall spacecraft mass reduction. Closed-Brayton-cycle (CBC) power conversion technology is viewed as relatively mature. At the 2-kWe power level, a CBC conversion system Technology Readiness Level (TRL) of six (6) was achieved during the Solar Dynamic Ground Test Demonstration (SD-GTD) in 1998. A TRL 5 was demonstrated for 10 kWe-class CBC components during the development of the Brayton Rotating Unit (BRU) from 1968 to 1976. Components currently in terrestrial (open cycle) Brayton machines represent TRL 4 for similar uses in 100 kWe-class CBC space systems. Because of the baseline component and subsystem technology maturity, much of the Brayton technology task is focused on issues related to systems integration. A brief description of ongoing technology activities is given.

Yellow mealworm (Tenebrio molitor L.) is one of the animal candidates for space bioregenerative life support systems. In this study, T. molitor was involved in a 105-day multi-crew closed integrative BLSS experiment for a tentative rearing study. The results showed that the overall bioconversion rate (ratio of T. molitor gained to the total feed consumed) of T. molitor reared in the closed system was 8.13%, while 78.43% of the feed was excreted as frass. T. molitor reared in the closed system had a good nutritional composition. The eight essential amino acids (EAAs) in T. molitor larvae accounted for 41.30% of its total amino acids, and most EAA contents were higher than the suggested amino acid pattern recommended by the FAO/WHO. T. molitor sample obtained in this work was high in polyunsaturated fatty acids, and low in saturated fatty acids, indicating that the composition of fatty acids was beneficial to human health. In the open environment outside the experimental system, we simultaneously reared three parallel groups of larval T. molitor using the same feeding regime and temperature condition. Compared with T. molitor reared in the open environment, larvae reared in the closed system grew slower. With the course of time t, the growth rate of T. molitor in the open environment was 0.839e(0.017t) times that of larvae in the closed system. This paper can provide data for future design and improvement of BLSS containing a T. molitor rearing unit. Copyright © 2015 The Committee on Space Research (COSPAR). Published by Elsevier Ltd.

Nonlinear mathematical modeling and sensitivity analysis of hydraulic drive unit

NASA Astrophysics Data System (ADS)

Kong, Xiangdong; Yu, Bin; Quan, Lingxiao; Ba, Kaixian; Wu, Liujie

2015-09-01

The previous sensitivity analysis researches are not accurate enough and also have the limited reference value, because those mathematical models are relatively simple and the change of the load and the initial displacement changes of the piston are ignored, even experiment verification is not conducted. Therefore, in view of deficiencies above, a nonlinear mathematical model is established in this paper, including dynamic characteristics of servo valve, nonlinear characteristics of pressure-flow, initial displacement of servo cylinder piston and friction nonlinearity. The transfer function block diagram is built for the hydraulic drive unit closed loop position control, as well as the state equations. Through deriving the time-varying coefficient items matrix and time-varying free items matrix of sensitivity equations respectively, the expression of sensitivity equations based on the nonlinear mathematical model are obtained. According to structure parameters of hydraulic drive unit, working parameters, fluid transmission characteristics and measured friction-velocity curves, the simulation analysis of hydraulic drive unit is completed on the MATLAB/Simulink simulation platform with the displacement step 2 mm, 5 mm and 10 mm, respectively. The simulation results indicate that the developed nonlinear mathematical model is sufficient by comparing the characteristic curves of experimental step response and simulation step response under different constant load. Then, the sensitivity function time-history curves of seventeen parameters are obtained, basing on each state vector time-history curve of step response characteristic. The maximum value of displacement variation percentage and the sum of displacement variation absolute values in the sampling time are both taken as sensitivity indexes. The sensitivity indexes values above are calculated and shown visually in histograms under different working conditions, and change rules are analyzed. Then the sensitivity indexes values of four measurable parameters, such as supply pressure, proportional gain, initial position of servo cylinder piston and load force, are verified experimentally on test platform of hydraulic drive unit, and the experimental research shows that the sensitivity analysis results obtained through simulation are approximate to the test results. This research indicates each parameter sensitivity characteristics of hydraulic drive unit, the performance-affected main parameters and secondary parameters are got under different working conditions, which will provide the theoretical foundation for the control compensation and structure optimization of hydraulic drive unit.

This report summarizes previous investigations of aquatic biological communities, habitat, and contaminants in streams and selected large lakes within the Great Salt Lake Basins study unit as part of the U.S. Geological Survey?s National Water-Quality Assessment Program (NAWQA). The Great Salt Lake Basins study unit is one of 59 such units designed to characterize water quality through the examination of chemical, physical, and biological factors in surface and ground waters across the country. The data will be used to aid in the planning, collection, and analysis of biological information for the NAWQA study unit and to aid other researchers concerned with water quality of the study unit. A total of 234 investigations conducted during 1875-1998 are summarized in this report. The studies are grouped into three major subjects: (1) aquatic communities and habitat, (2) contamination of streambed sediments and biological tissues, and (3) lakes. The location and a general description of each study is listed. The majority of the studies focus on fish and macroinvertebrate communities. Studies of algal communities, aquatic habitat, riparian wetlands, and contamination of streambed sediment or biological tissues are less common. Areas close to the major population centers of Salt Lake City, Provo, and Logan, Utah, are generally well studied, but more rural areas and much of the Bear River Basin are lacking in detailed information, except for fish populations..

Power in health care organizations: contemplations from the first-line management perspective.

PubMed

Isosaari, Ulla

2011-01-01

The aim of this paper is to examine health care organizations' power structures from the first-line management perspective. What liable power structures derive from the theoretical bases of bureaucratic, professional and result based organizations, and what power type do health care organizations represent, according to the empirical data? The paper seeks to perform an analysis using Mintzberg's power configurations of instrument, closed system, meritocracy and political arena. The empirical study was executed at the end of 2005 through a survey in ten Finnish hospital districts in both specialized and primary care. Respondents were all first-line managers in the area and a sample of staff members from internal disease, surgical and psychiatric units, as well as out-patient and primary care units. The number of respondents was 1,197 and the response percentage was 38. The data were analyzed statistically. As a result, it can be seen that a certain kind of organization structure supports the generation of a certain power type. A bureaucratic organization generates an instrument or closed system organization, a professional organization generates meritocracy and also political arena, and a result-based organization has a connection to political arena and meritocracy. First line managers regarded health care organizations as instruments when staff regarded them mainly as meritocracies having features of political arena. Managers felt their position to be limited by rules, whereas staff members regarded their position as having lots of space and influence potential. If the organizations seek innovative and active managers at the unit level, they should change the organizational structure and redistribute the work so that there could be more space for meaningful management. This research adds to the literature and gives helpful suggestions that will be of interest to those in the position of first-line management in health care.

To evaluate the feasibility of a wearable artificial pancreas system, the Diabetes Assistant (DiAs), which uses a smart phone as a closed-loop control platform. Twenty patients with type 1 diabetes were enrolled at the Universities of Padova, Montpellier, and Virginia and at Sansum Diabetes Research Institute. Each trial continued for 42 h. The United States studies were conducted entirely in outpatient setting (e.g., hotel or guest house); studies in Italy and France were hybrid hospital-hotel admissions. A continuous glucose monitoring/pump system (Dexcom Seven Plus/Omnipod) was placed on the subject and was connected to DiAs. The patient operated the system via the DiAs user interface in open-loop mode (first 14 h of study), switching to closed-loop for the remaining 28 h. Study personnel monitored remotely via 3G or WiFi connection to DiAs and were available on site for assistance. The total duration of proper system communication functioning was 807.5 h (274 h in open-loop and 533.5 h in closed-loop), which represented 97.7% of the total possible time from admission to discharge. This exceeded the predetermined primary end point of 80% system functionality. This study demonstrated that a contemporary smart phone is capable of running outpatient closed-loop control and introduced a prototype system (DiAs) for further investigation. Following this proof of concept, future steps should include equipping insulin pumps and sensors with wireless capabilities, as well as studies focusing on control efficacy and patient-oriented clinical outcomes.

2008-10-01

Behavior models have provided an accident proneness concept based on life change unit (LCU) factors. This paper describes the development of a Korean Life Change Unit (KLCU) model for workers and managers in fatal accident areas, as well as an evaluation of its application. Results suggest that death of parents is the highest stress-giving factor for employees of small and medium sized industries a rational finding the viewpoint of Korean culture. The next stress-giving factors were shown to be the death of a spouse or loved ones, followed by the death of close family members, the death of close friends, changes of family members' health, unemployment, and jail terms. It turned out that these factors have a serious effect on industrial accidents and work-related diseases. The death of parents and close friends are ranked higher in the KLCU model than that of Western society. Crucial information for industrial accident prevention in real fields will be provided and the provided information will be useful for safety management programs related to accident prevention.

One-Two Punch: Utilizing Teacher Research Experiences and Related Classroom Activities to Increase Student Interest in STEM

NASA Astrophysics Data System (ADS)

Wold-Brennon, R.; Cooper, S. K.

2014-12-01

Through collaborations between scientists and educators, the Consortium for Ocean Leadership developed a series of marine geosciences classroom activities and lesson plans -- including the Adopt-a-Microbe project, a collection of hands-on science lessons that use the sub-seafloor microbiology topics to provide engaging pathways for K-12 students to learn about the world around them. The goal of these activities has been to introduce youth to deep ocean exploration, inspire interest in microbial oceanography, and foster higher education goals and career paths in related sciences for our youth. From the beginning, these lessons were developed in close working relationships between scientists and educators, and the lessons geared towards middle school have been recently piloted with the intent to maximize sustained student interest in STEM topics. While teaching these units, educators used surveys, polls, group discussions, and interviews to shed light on correlations between student interest in STEM and their close proximity to exemplary and enthusiastic educators and student leaders who are active in STEM activities such as research projects and expeditions. Educators continue to use Adopt-a-Microbe and related expedition science-based lessons to explore the broader impacts of their professional development in the Geosciences on their students' professed interest in STEM.

Reasoning in molecular genetics: From a cognitive model to instructional design

NASA Astrophysics Data System (ADS)

Duncan, Ravit Golan

Effective instruction strives to help students construct deep and meaningful understandings in a domain. A key component of designing such instruction is a good understanding of relevant aspects of student cognition in the domain. This entails understanding both the cognitive obstacles to learning and the knowledge elements that are crucial to successful reasoning in the domain. While understandings of student cognition are not a prescription for design, they can nonetheless help instructional-designers and design-researchers focus the design and suggest where and what scaffolding should be incorporated into the instructional sequence and activities. In this dissertation I first discuss my research of the cognitive aspects of reasoning in molecular genetics. By studying both high school and college level students' reasoning about genetic phenomena, I have constructed a conceptual model of reasoning in this domain. The model depicts critical types of domain-specific knowledge, the relationships between them, and their role in facilitating reasoning about genetic phenomena. I then describe the design and evaluation of a high school project-based curricular unit in genetics. The unit was developed by a collaborative team of teachers and a researcher and was enacted in a local public high school. The design process was closely guided by our understandings of student cognition in genetics and the resulting instructional intervention was aimed at scaffolding student engagement with important disciplinary strategies and concepts.

Biofeedback for Better Vision

NASA Technical Reports Server (NTRS)

1990-01-01

Biofeedtrac, Inc.'s Accommotrac Vision Trainer, invented by Dr. Joseph Trachtman, is based on vision research performed by Ames Research Center and a special optometer developed for the Ames program by Stanford Research Institute. In the United States, about 150 million people are myopes (nearsighted), who tend to overfocus when they look at distant objects causing blurry distant vision, or hyperopes (farsighted), whose vision blurs when they look at close objects because they tend to underfocus. The Accommotrac system is an optical/electronic system used by a doctor as an aid in teaching a patient how to contract and relax the ciliary body, the focusing muscle. The key is biofeedback, wherein the patient learns to control a bodily process or function he is not normally aware of. Trachtman claims a 90 percent success rate for correcting, improving or stopping focusing problems. The Vision Trainer has also proved effective in treating other eye problems such as eye oscillation, cross eyes, and lazy eye and in professional sports to improve athletes' peripheral vision and reaction time.

Toward a Social Psychology of Race and Race Relations for the Twenty-First Century.

Richeson, Jennifer A; Sommers, Samuel R

2016-01-01

The United States, like many nations, continues to experience rapid growth in its racial minority population and is projected to attain so-called majority-minority status by 2050. Along with these demographic changes, staggering racial disparities persist in health, wealth, and overall well-being. In this article, we review the social psychological literature on race and race relations, beginning with the seemingly simple question: What is race? Drawing on research from different fields, we forward a model of race as dynamic, malleable, and socially constructed, shifting across time, place, perceiver, and target. We then use classic theoretical perspectives on intergroup relations to frame and then consider new questions regarding contemporary racial dynamics. We next consider research on racial diversity, focusing on its effects during interpersonal encounters and for groups. We close by highlighting emerging topics that should top the research agenda for the social psychology of race and race relations in the twenty-first century.

Research on Geographical Environment Unit Division Based on the Method of Natural Breaks (Jenks)

NASA Astrophysics Data System (ADS)

2013-11-01

Zoning which is to divide the study area into different zones according to their geographical differences at the global, national or regional level, includes natural division, economic division, geographical zoning of departments, comprehensive zoning and so on. Zoning is of important practical significance, for example, knowing regional differences and characteristics, regional research and regional development planning, understanding the favorable and unfavorable conditions of the regional development etc. Geographical environment is arising from the geographical position linkages. Geographical environment unit division is also a type of zoning. The geographical environment indicators are deeply studied and summed up in the article, including the background, the associated and the potential. The background indicators are divided into four categories, such as the socio-economic, the political and military, the strategic resources and the ecological environment, which can be divided into more sub-indexes. While the sub-indexes can be integrated to comprehensive index system by weighted stacking method. The Jenks natural breaks classification method, also called the Jenks optimization method, is a data classification method designed to determine the best arrangement of values into different classes. This is done by seeking to minimize each class's average deviation from the class mean, while maximizing each class's deviation from the means of the other groups. In this paper, the experiment of Chinese surrounding geographical environment unit division has been done based on the natural breaks (jenks) method, the geographical environment index system and the weighted stacking method, taking South Asia as an example. The result indicates that natural breaks (jenks) method is of good adaptability and high accuracy on the geographical environment unit division. The geographical environment research was originated in the geopolitics and flourished in the geo-economics. The main representatives of the geopolitics are German geographer Friedrich Ratzel, British geographer Mackinder and American geographical politician Nicholas John Spykman etc. The main representative of the geo-economics is American geographical economist Edward Luttwak. China has the most neighboring countries in the world, and its geographical environment is extremely complex. With the continuous development of globalization, China's relations with neighboring countries have become more complex and more closely. So it is very meaningful to have depth research on geographical environment unit division of China.

Aerospace medicine at Brooks AFB, TX: hail and farewell.

PubMed

Nunneley, Sarah A; Webb, James T

2011-05-01

With the impending termination of USAF operations at Brooks Air Force Base (AFB) in San Antonio, TX, it is time to consider its historic role in Aerospace Medicine. The base was established in 1917 as a flight training center for the U.S. Army Air Service and in 1926 became home to its School of Aviation Medicine. The school moved to San Antonio's Randolph Field in 1931, but in 1959 it returned to Brooks where it occupied new facilities to support its role as a national center for U.S. Air Force aerospace medicine, including teaching, clinical medicine, and research. The mission was then expanded to encompass support of U.S. military and civilian space programs. With the abrupt termination of the military space program in 1969, research at Brooks focused on clinical aviation medicine and support of advanced military aircraft while continuing close cooperation with NASA in support of orbital spaceflight and the journey to the Moon. Reorganization in the 1990s assigned all research functions at Brooks to the Human Systems Division and its successors, leaving to USAFSAM the missions related to clinical work and teaching. In 2002 the USAF and the city of San Antonio implemented shared operation of Brooks as a "City-Base" in the hope of deflecting threatened closure. Nevertheless, under continuing pressure to consolidate military facilities in the United States, the 2005 Base Closure and Realignment Commission ordered Brooks closed by 2011, with its aerospace medicine functions relocated to new facilities at Wright-Patterson AFB in Dayton, OH.

Spacelab

NASA Image and Video Library

1992-06-01

The first United States Microgravity Laboratory (USML-1) was one of NASA's science and technology programs that provided scientists an opportunity to research various scientific investigations in a weightlessness environment inside the Spacelab module. It also provided demonstrations of new equipment to help prepare for advanced microgravity research and processing aboard the Space Station. The USML-1 flew in orbit for extended periods, providing greater opportunities for research in materials science, fluid dynamics, biotechnology (crystal growth), and combustion science. This is a close-up view of the Drop Physics Module (DPM) in the USML science laboratory. The DPM was dedicated to the detailed study of the dynamics of fluid drops in microgravity: their equilibrium shapes, the dynamics of their flows, and their stable and chaotic behaviors. It also demonstrated a technique known as containerless processing. The DPM and microgravity combine to remove the effects of the container, such as chemical contamination and shape, on the sample being studied. Sound waves, generating acoustic forces, were used to suspend a sample in microgravity and to hold a sample of free drops away from the walls of the experiment chamber, which isolated the sample from potentially harmful external influences. The DPM gave scientists the opportunity to test theories of classical fluid physics, which have not been confirmed by experiments conducted on Earth. This image is a close-up view of the DPM. The USML-1 flew aboard the STS-50 mission on June 1992, and was managed by the Marshall Space Flight Center.

Stakeholders' engagement with Ebola therapy research in resource limited settings.

2015-06-26

The current Ebola Virus Disease (EVD) outbreak in West Africa is the largest in history. As of February 18(th) 2015, 23,258 cases of EVD have been cumulatively reported from Nigeria, Senegal, Guinea, Liberia, Mali, Sierra Leone, Spain, the United Kingdom and the United States of America resulting in more than 9,000 deaths. It is therefore exigent to develop prevention and treatment therapies for EVD. Several new EVD treatments are in clinical development at this time. Based on lessons learned, four critical processes need to be implemented before clinical trials begin. First, all global EVD research need to be coordinated to promote data sharing and synergistic overlap, while reducing unnecessary duplication of efforts. The World Health Organization is well-placed to undertake such an endeavor. Second, governments of affected nations where trials are being proposed need to lead discussions regarding immediate access to any proven medications for epidemics. Also, governments need to leverage international resources to support and expand existing national expertise to jointly conduct high-caliber clinical research; and resources must be used to enhance local technical skills and expand existing personnel. Third, ethics committees must review protocols, monitor the research process, and work closely with research scientists to insure the ethical integrity of research throughout the trials. Fourth, community advisory boards (CAB) need to be formed, linked with existing community leadership structures and organized in conjunction with trial implementation. These community structures should work together with ethics committees to facilitate the study design, informed consent process, and study implementation. We must facilitate communication and mutual understanding between trial communities and research teams, and promote positive collaborations between all stakeholders engaged in EVD research. The community engagement process for EVD research is crucial to address myths and misconceptions, and to promote study volunteers' understanding of the research details. The collaboration between all stakeholders is crucial for continued long term partnership to address EVD outbreak and none of the stakeholders should be left behind in ongoing efforts to develop EVD therapies.

Efficacy and enlightenment: LSD psychotherapy and the Drug Amendments of 1962.

PubMed

Oram, Matthew

2014-04-01

The decline in therapeutic research with lysergic acid diethylamide (LSD) in the United States over the course of the 1960s has commonly been attributed to the growing controversy surrounding its recreational use. However, research difficulties played an equal role in LSD psychotherapy's demise, as they frustrated researchers' efforts to clearly establish the efficacy of treatment. Once the Kefauver Harris Drug Amendments of 1962 introduced the requirement that proof of efficacy be established through controlled clinical trials before a drug could be approved to market, the value of clinical research became increasingly dependent on the scientific rigor of the trial's design. LSD psychotherapy's complex method of utilizing drug effects to catalyze a psychological treatment clashed with the controlled trial methodology on both theoretical and practical levels, making proof of efficacy difficult to obtain. Through a close examination of clinical trials performed after 1962, this article explores how the new emphasis on controlled clinical trials frustrated the progress of LSD psychotherapy research by focusing researchers' attention on trial design to the detriment of their therapeutic method. This analysis provides a new perspective on the death of LSD psychotherapy and explores the implications of the Drug Amendments of 1962.

2007-06-01

Team work is considered a central component of palliative care. Within this comparatively young field of medicine, the emergence of new institutions (eg, palliative care units) highlights the challenge of establishing a completely new team. This study focuses on the factors, which enhance both the success and outcome criteria of good team work from the perception of team members in a palliative care unit. The palliative care team at the University Hospital of Aachen (n = 19) was interviewed 1 year after the unit's startup by the means of semistructured interviews. Interview texts were analysed using qualitative content analysis. Factors crucial to cooperation in the team members' views were close communication, team philosophy, good interpersonal relationships, high team commitment, autonomy and the ability to deal with death and dying. Moreover, close communication was by far the most frequently mentioned criteria for cooperation. Team performance, good coordination of workflow and mutual trust underpin the evaluation of efficient team work. Inefficient team work is associated with the absence of clear goals, tasks and role delegation, as well as a lack of team commitment. In a new team, close communication is particularly important for staff as they reorientate themselves to the dynamics of a new peer group. The results confirm the overwhelming importance of clarity, commitment and close, positive exchange among team members for successful team work.

Introduction to workshop on iron screening and supplementation in iron-replete pregnant women and young children.

Taylor, Christine L; Brannon, Patsy M

2017-12-01

The NIH Office of Dietary Supplements convened a public workshop on iron screening and supplementation in iron-replete pregnant women and young children in 2016 in Bethesda, Maryland. The starting point for the workshop was the recent reports from the US Preventive Services Task Force concluding that there was insufficient evidence to evaluate the benefits and harms associated with iron screening and routine supplementation among asymptomatic pregnant women and young children (6-24 mo old) in the United States. The goal of the workshop was to explore and refine understanding about the existing knowledge gaps and research needs associated with these preventive services for these groups. Given the focus on the United States, planning for the workshop took into account the higher iron status in the United States compared with developing countries and, in turn, included a focus on iron-replete individuals consistent with the U-shaped risk curve for nutrient-health relations. Topic areas included adaptations in iron homeostasis associated with pregnancy and young childhood, the impact of inflammation, measurement of iron status, current estimates of iron status for pregnant women and young children in the United States and in Europe, and emerging evidence suggesting adverse effects associated with iron supplementation of iron-replete individuals. A crosscutting dialogue conducted at the close of the workshop formed the basis for a workshop summary that specified evidence gaps and research needs in a range of areas centered on the relation of these adaptations of iron homeostasis with the response to and risk from iron supplementation as well as the need for indicators informative of the full continuum of iron status and based on health outcomes, not just erythropoiesis. © 2017 American Society for Nutrition.

Columbus Closure Project Released without Radiological Restrictions

DOE Office of Scientific and Technical Information (OSTI.GOV)

Henderson, G.

2007-07-01

The Columbus Closure Project (CCP), a historic radiological research complex, was cleaned up for future use without radiological restriction in 2006. The CCP research and development site contributed to national defense, nuclear fuel fabrication, and the development of safe nuclear reactors in the United States until 1988 when research activities were concluded for site decommissioning. In November of 2003, the Ohio Field Office of the U.S. Department of Energy contracted ECC/E2 Closure Services, LLC (Closure Services) to complete the removal of radioactive contamination from of a 1955 era nuclear sciences area consisting of a large hot cell facility, research reactormore » building and underground piping. The project known as the Columbus Closure Project (CCP) was completed in 27 months and brought to a close 16 years of D and D in Columbus, Ohio. This paper examines the project innovations and challenges presented during the Columbus Closure Project. The examination of the CCP includes the project regulatory environment, the CS safety program, accelerated clean up innovation, project execution strategies and management of project waste issues and the regulatory approach to site release 'without radiological restrictions'.

The Brayton Power Conversion Unit (BPCU) is a closed cycle system with an inert gas working fluid. It is located in Vacuum Facility 6 at NASA Glenn Research Center. Was used in previous solar dynamic technology efforts (SDGTD). Modified to its present configuration by replacing the solar receiver with an electrical resistance heater. The first closed-Brayton-cycle to be coupled with an ion propulsion system. Used to examine mechanical dynamic characteristics and responses. The focus of this work was the validation of a computer model of the BPCU. Model was built using the Closed Cycle System Simulation (CCSS) design and analysis tool. Test conditions were then duplicated in CCSS. Various steady-state points. Transients involving changes in shaft rotational speed and heat input. Testing to date has shown that the BPCU is able to generate meaningful, repeatable data that can be used for computer model validation. Results generated by CCSS demonstrated that the model sufficiently reproduced the thermal transients exhibited by the BPCU system. CCSS was also used to match BPCU steady-state operating points. Cycle temperatures were within 4.1% of the data (most were within 1%). Cycle pressures were all within 3.2%. Error in alternator power (as much as 13.5%) was attributed to uncertainties in the compressor and turbine maps and alternator and bearing loss models. The acquired understanding of the BPCU behavior gives useful insight for improvements to be made to the CCSS model as well as ideas for future testing and possible system modifications.

Bozeman, Montana, United States - mike@adventureandscience.org(2) College of the Atlantic. Bar Harbor, Maine, United States - abby.barrows@coa.eduSince World War II, global plastic production and consumption has increased dramatically. Plastics released into the environment may break down into smaller pieces through physical, biological and chemical processes. These small particles, referred to as microplastics, are less than 5mm in size and are a pollutant of emerging concern in both marine and freshwater environments. Since 2013, researcher Abigail Barrows and ASC have been conducting a global survey of microplastic distribution by utilizing the outdoor skills of adventurers. ASC recruits, trains and manages volunteers with specialized skills (surfers, long-distance open-ocean rowers, sailors, hikers, mountaineers, kayakers and others) to collect marine and freshwater samples from remote environments. Of the nearly 1500 samples collected worldwide to date (from areas as remote as the edge of Antarctica and the wilderness of Alaska) 90% contain microplastic, with an average of 8 pieces/1L of water. Samples are also in preparation for micro-Raman spectroscopy to determine source materials. In 2016 and 2017 the survey is focusing on freshwater around the globe. In the United States samples are being collected from the length of the 4th longest river system in the world, the Missouri-Mississippi. ASC has adventurous citizen scientists sampling in the mountain headwaters near Yellowstone National Park to the delta of the Mississippi River near New Orleans. This citizen-driven observation allows research at a geographic scale simply not possible through traditional methods. ASC works closely with Barrows and other researchers to develop water sampling protocols that allow volunteers to collect research grade data. This includes the use of POV cameras to review volunteers' sample collection methods, incorporating self-assessment into data collection, online training and refreshers, and app-based field data recording.

The botánica as a culturally appropriate health care option for Latinos.

PubMed

Gomez-Beloz, A; Chavez, N

2001-10-01

The purpose of this study was to make a preliminary assessment of the botánica as a culturally appropriate health care option for Latinos in the United States. Closed-ended interviews were carried out using a questionnaire with 26 customers of a botánica located in a primarily urban Mexican American community in the United States. Sample gender was predominantly female with an average age of 38 years and income in the range of $15,000-$29,999 per year. Most participants were married (16), had children (17), and most (22) had formal education. Products purchased at the botánica included herbs, religious amulets, and other products. Although botánicas are commonly believed to provide remedies only for folk illnesses, the participants in this study reported seeking remedies primarily for somatic illnesses. The respondents used the services of conventional health care providers interchangeably with the botánica, making the botánica an important health care resource for Latinos in the United States. Further research should be carried out to better understand the role of botánicas in health care delivery.

When politics meets science: What impact might Brexit have on organ donation and transplantation in the United Kingdom?

Brexit may lead to major political, societal, and financial changes-this has significant implications for a tax revenue funded healthcare system such as the United Kingdom's (UK) National Health Service. The complex relationship between European Union (EU) legislation and clinical practice of organ donation and transplantation is poorly understood. However, it is unclear what impact Brexit may have on organ donation and transplantation in the UK and EU. This work aims to describe the current legislative interactions affecting organ donation and transplantation regulation and governance within the UK and EU. We consider the potential impact of Brexit on the practical aspects of transplantation such organ-sharing networks, logistics, and the provision of health care for transplant patients when traveling to the EU from the UK and vice versa, as well as personnel, and research. Successful organ donation and transplantation practices rely on close collaboration and co-operation across Europe and throughout the United Kingdom. The continuation of such relationships, despite the proposed legislative change, will remain a vital and necessary component for the ongoing success of transplantation programs. © 2018 The Authors.

Bean, Corliss N; Fortier, Michelle; Post, Courtney; Chima, Karam

2014-10-01

Within the United States, close to 45 million youths between the ages of 6 and 18 participate in some form of organized sports. While recent reviews have shown the positive effects of youth sport participation on youth health, there are also several negative factors surrounding the youth sport environment. To date, a comprehensive review of the negative physical and psychological effects of organized sport on youth has not been done and little to date has documented the effect organized sport has on other players within a family, particularly on parents and siblings. Therefore the purpose of this paper is to conduct a review of papers on the negative effects of organized sport on the youth athlete and their parents and siblings. Articles were found by searching multiple databases (Physical Education Index and Sociology, Psychology databases (Proquest), SPORTDiscus and Health, History, Management databases (EBSCOhost), Science, Social Science, Arts and Humanities on Web of Science (ISI), SCOPUS and Scirus (Elsevier). Results show the darker side of organized sport for actors within the family unit. Ideas for future research are drawn and recommendations are made to optimize the youth sport experience and family health.

The study of urban spatial interaction is closely linked to that of economic geography, urban planning, regional development, and so on. Currently, this topic is generating a great deal of interest among researchers who are striving to find accurate ways to measure urban spatial interaction. Classical spatial interaction models lack theoretical guidance and require complicated parameter-adjusting processes. The radiation model, however, as proposed by Simini et al. with rigorous formula derivation, can simulate directional urban spatial interaction. We applied the radiation model in China to simulate the directional migration number among 337 nationwide research units, comprising 4 municipalities and 333 prefecture-level cities. We then analyzed the overall situation in Chinese cities, the interaction intensity hierarchy, and the prime urban agglomerations from the perspective of migration. This was done to ascertain China’s urban spatial interaction and regional development from 2000 to 2010 to reveal ground realities. PMID:28141853

Barta, William D.; Shelton, Deborah; Cepelak, Cheryl; Gallagher, Colleen

2015-01-01

In the United States, the phenomenon of mass incarceration has created a public health crisis. One strategy for addressing this crisis involves developing a correctional agency – academic institution partnership tasked with augmenting the quality and quantity of evidence-based healthcare delivered in state prisons and attracting a greater number of health professionals to the field of correctional health research. Using a Connecticut correctional agency – academic institution partnership as a case example, the present paper examines some of the key challenges encountered over the course of a 3-year capacity-building initiative. Particular attention is given to agency and institution characteristics both at the structural level and in terms of divergent stakeholder perspectives. The authors find that future partnership development work in this area will likely benefit from close attention to predictable sources of temporal variation in agency capability to advance project-related aims.

A topological index of graph G is a numerical parameter related to G which characterizes its molecular topology and is usually graph invariant. In the field of quantitative structure-activity (QSAR)/quantitative structure-activity structure-property (QSPR) research, theoretical properties of the chemical compounds and their molecular topological indices such as the Randić connectivity index, atom-bond connectivity (ABC) index and geometric-arithmetic (GA) index are used to predict the bioactivity of different chemical compounds. A dendrimer is an artificially manufactured or synthesized molecule built up from the branched units called monomers. In this paper, the fourth version of ABC index and the fifth version of GA index of certain families of nanostar dendrimers are investigated. We derive the analytical closed formulas for these families of nanostar dendrimers. The obtained results can be of use in molecular data mining, particularly in researching the uniqueness of tested (hyper-branched) molecular graphs.

Nuclear quadrupole resonance detection of explosives: an overview

NASA Astrophysics Data System (ADS)

Miller, Joel B.

2011-06-01

Nuclear Quadrupole Resonance (NQR) is a spectroscopic technique closely related to Nuclear Magnetic Resonance (NMR) and Magnetic Resonance Imaging (MRI). These techniques, and NQR in particular, induce signals from the material being interrogated that are very specific to the chemical and physical structure of the material, but are relatively insensitive to the physical form of the material. NQR explosives detection exploits this specificity to detect explosive materials, in contrast to other well known techniques that are designed to detect explosive devices. The past two decades have seen a large research and development effort in NQR explosives detection in the United States aimed at transportation security and military applications. Here, I will briefly describe the physical basis for NQR before discussing NQR developments over the past decade, with particular emphasis on landmine detection and the use of NQR in combating IED's. Potential future directions for NQR research and development are discussed.

Key Data Gaps Regarding the Public Health Issues Associated with Opioid Analgesics

Schmidt, Teresa D.; Haddox, J. David; Nielsen, Alexandra E.; Wakeland, Wayne; Fitzgerald, John

2014-01-01

Most pharmaceutical opioids are used to treat pain and they have been demonstrated to be effective medications for many. Their abuse and misuse pose significant public health concerns in the United States. Research has provided much insight into the prevalence, scope, and drivers of opioid abuse, but a holistic understanding is limited by a lack of available data regarding key aspects of this public health problem. Twelve data gaps were revealed during the creation of a systems-level computer model of medical use, diversion, nonmedical use, and the adverse outcomes associated with opioid analgesics in the United States. Data specific to these gaps would enhance the validity and real-world applications of systems-level models of this public health problem, and would increase understanding of the complex system in which use and abuse occur. This paper provides an overview of these gaps, argues for the importance of closing them, and provides specific recommendations for future data collection efforts. PMID:24554390

Privatization in a publicly funded health care system: the U.S. experience.

PubMed

Himmelstein, David U; Woolhandler, Steffie

2008-01-01

The United States has four decades of experience with the combination of public funding and private health care management and delivery, closely analogous to reforms recently enacted or proposed in many other nations. Extensive research, herein reviewed, shows that for-profit health institutions provide inferior care at inflated prices. The U.S. experience also demonstrates that market mechanisms nurture unscrupulous medical businesses and undermine medical institutions unable or unwilling to tailor care to profitability. The commercialization of care in the United States has driven up costs by diverting money to profits and by fueling a vast increase in management and financial bureaucracy, which now consumes 31 percent of total health spending. The Veterans Health Administration system--a network of government hospitals and clinics--has emerged as the leader in quality improvement and information technology, indicating the potential for public sector excellence and innovation. The poor performance of U.S. health care is directly attributable to reliance on market mechanisms and for-profit firms, and should warn other nations from this path.

Re-visiting the Causes of Cancer

Cancer.gov

Sir Richard Peto, FRS, is Professor of Medical Statistics and Epidemiology at the University of Oxford, UK, and Co-Director of the Clinical Trial Service Unit and Epidemiological Studies Unit (CTSU). He collaborated for decades with Richard Doll on cancer epidemiology, and in 1981, they co-authored an influential report, “The Causes of Cancer – Quantitative estimates of avoidable risks of cancer in the US today” (JNCI 66:1191). Since then, his close attention to the details of how epidemiological evidence and trial evidence is interpreted has shown that the importance of factors such as tobacco, blood pressure and cholesterol have been much underestimated: we actually know more than we thought we did about major avoidable causes of cancer and of vascular disease. In 1989, Peto was made a Fellow of the Royal Society of London for introducing meta-analyses of randomised trials, was knighted by Queen Elizabeth in 1999 for services to epidemiology, and received in 2010 and 2011 the Cancer Research UK and the BMJ Lifetime Achievement Award.

800 Hours of Operational Experience from a 2 kW(sub e) Solar Dynamic System

Shaltens, Richard K.; Mason, Lee S.

1999-01-01

From December 1994 to September 1998, testing with a 2 kW(sub e) Solar Dynamic power system resulted in 33 individual tests, 886 hours of solar heating, and 783 hours of power generation. Power generation ranged from 400 watts to over 2 kW(sub e), and SD system efficiencies have been measured up to 17 per cent, during simulated low-Earth orbit operation. Further, the turbo-alternator-compressors successfully completed 100 start/stops on foil bearings. Operation was conducted in a large thermal/vacuum facility with a simulated Sun at the NASA Lewis Research Center. The Solar Dynamic system featured a closed Brayton conversion unit integrated with a solar heat receiver, which included thermal energy storage for continuous power output through a typical low-Earth orbit. Two power conversion units and three alternator configurations were used during testing. This paper will review the test program, provide operational and performance data, and review a number of technology issues.

Sex Differences in Virtual Network Characteristics and Sexual Risk Behavior among Emerging Adults

Cook, Stephanie H.; Bauermeister, José A.; Zimmerman, Marc A.

2016-01-01

Emerging adults (EAs)ages 18 to 24 account for a large proportion of all sexually transmitted infections (STIs), HIV infections, and unintended pregnancies in the United States. Given the increased influence of online media on decision-making, we examined how EA online networks were associated with sexual risk behaviors. We used egocentric network data collected from EAs aged 18 to 24 years old across the United States (N=1,687) to examine how online norms (e.g., acceptance of HIV infections, other STIs, and pregnancy) and network characteristics (i.e., network size and density; ties' closeness, race, age, and sex similarities) were associated with participants' unprotected vaginal intercourse (UVI) in the last 30 days. Findings suggested that in male EAs, there was a strong association between sexual norms, structural characteristics, and sexual risk behavior compared to females. Researchers and practitioners may wish to address online peer norms and EAs' online network composition when developing online sexual risk prevention tools. PMID:28083447

Exposure to the Tips From Former Smokers Campaign Among Adolescents in the United States.

PubMed

Zhao, Xiaoquan; Cai, Xiaomei

2016-05-01

Evaluation of the Tips from Former Smokers (Tips) campaign in the United States so far has focused exclusively on adult smokers. This study provides evidence on the level of exposure to Tips among adolescents in the United States, an important secondary audience for the campaign. Data came from the 2013 National Youth Tobacco Survey (N = 18 406). Exposure to Tips was measured by ad recall. Characteristics of adolescents reporting exposure versus no exposure were examined through a series of bivariate analysis linking exposure to smoking status, demographics, and important risk factors. Most adolescents in the United States (63%, 95% confidence interval [CI] = 60.6%, 65.3%) were exposed to at least one Tips ad. Current smokers (70.6%, 95% CI = 67.7%, 73.4%), noncurrent smokers (67.7%, 95% CI = 65.5%, 69.7%), and high-risk never-smokers (63.8%, 95% CI = 60.2%, 67.2%) reported greater exposure than low-risk never-smokers (60.7%, 95% CI = 57.8%, 63.5%; all P < .05). Those who reported exposure were more likely to be female; be older in age; be white (vs. Hispanic); live with a smoker; have less firm smoking rules in the family; have one or more friends using tobacco or are not sure; have been exposed to tobacco advertising from one or more sources; and have skipped classes in the past 30 days. Tips has significant reach among adolescents in the United States, particularly among those with smoking experience and those whose life environments include more pro-smoking influences. Close monitoring of the Tips' impact on this important population is needed. This study shows substantial adolescent awareness of the Tips campaign in the United States. This evidence has important implications for the comprehensive evaluation of the public health impact of Tips. So far research on Tips has focused almost entirely on adult smokers. Findings of this study suggest that the potential impact of Tips on adolescents, particularly those at high risk of smoking, should become an integral part of the evaluation research agenda. © The Author 2015.

You say "lean finely textured beef," I say "pink slime".

PubMed

Reid, Rita-Marie Cain

2014-01-01

In 2012, American Broadcasting Companies, Inc. (ABC) broadcast a segment on its evening news show regarding the manufacture of "lean finely textured beef" by Beef Products, Inc. (BPI). The broadcast, as well as follow-up reports and social media communications, repeatedly referred to the product as "pink slime," a term originated by a United States Department of Agriculture (USDA) employee for the processed meat. The market backlash against the product was immediate and intense. Ultimately, BPI closed three processing plants, cut hundreds of jobs, and filed for bankruptcy. BPI sued ABC and others for food libel, defamation, and tortious interference. This research analyzes those claims and defenses and discusses the future of such cases.

Monitoring Potential Transport of Radioactive Contaminants in Shallow Ephemeral Channels: FY2015 and FY2016

Mizell, Steve A; Miller, Julianne J; McCurdy, Greg

The Desert Research Institute (DRI) is conducting a field assessment of the potential for contaminated soil to be transported from the Smoky Contamination Area (CA) as a result of storm runoff. This activity supports Nevada Nuclear Security Administration (NNSA) efforts to complete regulatory closure of the Soils Corrective Action Unit (CAU) contamination areas. The work is intended to confirm the likely mechanism of transport and determine the meteorological conditions that might cause movement of contaminated soils, as well as determine the particle size fraction that is most closely associated with transported radionuclide-contaminated soils.

Sociology, medicine and the construction of health-related sociology.

PubMed

Barros, Nelson Filice de; Nunes, Everardo Duarte

2009-02-01

Starting from a paper about closing the gap between sociology and medicine in Brazil and the United Kingdom that was published in 1971, a historical update was made with the aim of reflecting on the new shapes of health-related teaching and research within the social and human sciences, in these two countries. The methodology was qualitative and the study was developed using secondary data. The reflections were developed through the authors' immersion in Brazilian and British realities. It was concluded that the interface between sociology and health has expanded, although persistent old difficulties exist in relation to the structure and focus of the healthcare system, medical school power and medical student culture.

Battered police: risk factors for violence against law enforcement officers.

PubMed

Covington, Michele W; Huff-Corzine, Lin; Corzine, Jay

2014-01-01

Although we hear more about violence committed by the police, violence against police officers is also a major problem in the United States. Using data collected from the Orlando, Florida Police Department files, this study examines situational variables, offender characteristics, and officer demographics that may correlate with violence directed at law enforcement officers. Logistic regression results indicate that battery against one or more police officers is significantly more likely when multiple officers are involved, when offenders are women, when offenders are larger than average as measured by body mass index (BMI), and when offenders are known to have recently consumed alcohol. We close with a discussion of policy implications and directions for future research.

Regenerable Air Purification System for Gas-Phase Contaminant Control

NASA Technical Reports Server (NTRS)

Constantinescu, Ileana C.; Finn, John E.; LeVan, M. Douglas; Lung, Bernadette (Technical Monitor)

2000-01-01

Tests of a pre-prototype regenerable air purification system (RAPS) that uses water vapor to displace adsorbed contaminants from an adsorbent column have been performed at NASA Ames Research Center. A unit based on this design can be used for removing trace gas-phase contaminants from spacecraft cabin air or from polluted process streams including incinerator exhaust. During the normal operation mode, contaminants are removed from the air on the column. Regeneration of the column is performed on-line. During regeneration, contaminants are displaced and destroyed inside the closed oxidation loop. In this presentation we discuss initial experimental results for the performance of RAPS in the removal and treatment of several important spacecraft contaminant species from air.

Grover, Sandeep

2011-01-01

Over the years Consultation-Liaison (C-L) psychiatry has contributed significantly to the growth of the psychiatry and has brought psychiatry very close to the advances in the medicine. It has also led to changes in the medical education and in the providing comprehensive management to the physically ill. In India, although the General Hospital Psychiatric units were established in 1930s, C-L Psychiatry has never been the main focus of training and research. Hence there is an urgent need to improve C-L Psychiatry services and training to provide best and optimal care to the patients and provide best education to the trainees. PMID:22135437

Harvey Cushing and some Australian connections: part 1 - early life and work.

PubMed

Roxanas, M G

2010-02-01

Before World War 1 both the United States of America and Australia had rather rudimentary medical systems. Enterprising practitioners in both countries tended to look to continental Europe (especially Germany) and the United Kingdom as places of medical renown. The outbreak of World War 1 changed this but also enabled doctors from both the United States and Australia to work in military hospitals in Europe. The interactions that occurred were important for their professional development and led to some close associations between American and antipodean doctors. Examples of these were the experiences of Harvey Cushing, a burgeoning American neurosurgeon, which he recounted in his diary. His commentary merits close inspection and analysis. An account of some of Cushing's Australian connections post World War 1 is given in Part 2 (in press). Copyright 2009 Elsevier Ltd. All rights reserved.

Dekeyser, S; Beclin, E; Descamps, D

2011-04-01

The closed system PCR for the rapid detection of vanA and vanB genes (Xpert vanA/vanB Cepheid(®)) was evaluated in our laboratory, to improve the rapidity of the response and thus the management of patients and isolation measures during two GRE outbreaks. From March to December2009, 565 samples were analysed by PCR associated to bacterial culture initially for all samples for 2months (n = 75), and thereafter for PCR-positive samples only. In this study, sensitivity and negative predictive values of the PCR were 100%. Specificity was evaluated in the presence and absence of outbreak: 69.3 and 76.8% respectively. The variability of false positive rates between units were lower in nonepidemic than during epidemic phase. The global false positive rate was 23.9%. This easy-to-use technology provides rapid results… four samples are tested in 1h versus 72h for culture. Despite its reagent cost, it represents an important hospital diagnostic tool: improvement of the management of cohorting areas and patient transfer between units, adaptation of isolation measures and treatments. However, culture remains necessary to confirm any positive result obtained by PCR and for epidemiological surveillance. Copyright © 2010 Elsevier Masson SAS. All rights reserved.

REN, GANG; LIU, JINXIN; LI, HONGCHANG

A closed-loop proportional-integral (PI) control software is provided for fully mechanically controlled automated electron microscopic tomography. The software is developed based on Gatan DigitalMicrograph, and is compatible with Zeiss LIBRA 120 transmission electron microscope. However, it can be expanded to other TEM instrument with modification. The software consists of a graphical user interface, a digital PI controller, an image analyzing unit, and other drive units (i.e.: image acquire unit and goniometer drive unit). During a tomography data collection process, the image analyzing unit analyzes both the accumulated shift and defocus value of the latest acquired image, and provides the resultsmore » to the digital PI controller. The digital PI control compares the results with the preset values and determines the optimum adjustments of the goniometer. The goniometer drive unit adjusts the spatial position of the specimen according to the instructions given by the digital PI controller for the next tilt angle and image acquisition. The goniometer drive unit achieves high precision positioning by using a backlash elimination method. The major benefits of the software are: 1) the goniometer drive unit keeps pre-aligned/optimized beam conditions unchanged and achieves position tracking solely through mechanical control; 2) the image analyzing unit relies on only historical data and therefore does not require additional images/exposures; 3) the PI controller enables the system to dynamically track the imaging target with extremely low system error.« less

Cryopreservation of red blood cells.

PubMed

Lagerberg, Johan W

2015-01-01

Cryopreservation of red blood cell concentrates (RBCs) is an important method for maintaining an inventory of rare RBC units and managing special transfusion circumstances. The permeating additive glycerol is used as a cryoprotectant to protect RBCs against freezing damage. The use of thawed RBCs was hampered a 24-h outdating period due to potential bacterial contamination when a functionally open system was used for addition and removal of the glycerol. With the introduction of a functionally closed system for the glycerolization and deglycerolization of RBC units, extended post-thaw storage became possible. Here, we describe the cryopreservation of red blood cells according to the high-glycerol method, using a functionally closed processing system.

Solar energy receiver

Schwartz, Jacob

1978-01-01

An improved long-life design for solar energy receivers provides for greatly reduced thermally induced stress and permits the utilization of less expensive heat exchanger materials while maintaining receiver efficiencies in excess of 85% without undue expenditure of energy to circulate the working fluid. In one embodiment, the flow index for the receiver is first set as close as practical to a value such that the Graetz number yields the optimal heat transfer coefficient per unit of pumping energy, in this case, 6. The convective index for the receiver is then set as closely as practical to two times the flow index so as to obtain optimal efficiency per unit mass of material.

Ecohydrological controls on soil moisture and hydraulic conductivity within a pinyon‐juniper woodland

USGS Publications Warehouse

Lebron, I.; Madsen, M.D.; Chandler, D.G.; Robinson, D.A.; Wendroth, O.; Belnap, J.

2007-01-01

The impact of pinyon‐juniper woodland encroachment on rangeland ecosystems is often associated with a reduction of streamflow and recharge and an increase in soil erosion. The objective of this study is to investigate vegetational control on seasonal soil hydrologic properties along a 15‐m transect in pinyon‐juniper woodland with biocrust. We demonstrate that the juniper tree controls soil water content (SWC) patterns directly under the canopy via interception, and beyond the canopy via shading in a preferred orientation, opposite to the prevailing wind direction. The juniper also controls the SWC and unsaturated hydraulic conductivity measured close to water saturation (K(h)) under the canopy by the creation of soil water repellency due to needle drop. We use this information to refine the hydrologic functional unit (HFU) concept into three interacting hydrologic units: canopy patches, intercanopy patches, and a transitional unit formed by intercanopy patches in the rain shadow of the juniper tree. Spatial autoregressive state‐space models show the close relationship between K(h) close to soil water saturation and SWC at medium and low levels, integrating a number of influences on hydraulic conductivity.

Nearshore drift dynamics of natural versus artificial seagrass wrack

NASA Astrophysics Data System (ADS)

Baring, Ryan J.; Fairweather, Peter G.; Lester, Rebecca E.

2018-03-01

Drifting macrophytes such as seagrass and macroalgae are commonly found washed ashore on sandy beaches but few studies have investigated the drift trajectories of macrophytes whilst near to the coast. This is the first study to investigate the surface drifting of small clumps of seagrass released at various distances from shore, across multiple days with contrasting wind and tidal conditions, in a large gulf in southern Australia. Natural and artificial radio-tagged seagrass units generally travelled in the same directions as tides but trajectories were variable across sampling days and when tagged units were released at different distances from shore. Natural and artificial units diverged from each other particularly on days when wind speeds increased but generally drifted in the same direction and ended up within close proximity to each other at the 6-h endpoint. During calm conditions, tagged seagrass units drifted with tides for 0.25-5 km and, during one sampling day when wind speeds increased, drifted for >5 km over the 6-h time period. Only tagged units that were released closest to shore stranded on sandy beaches within the six hours of observation, so it would be difficult to predict the eventual stranding location on shorelines for macrophytes released further offshore. This study provides evidence of the variability of macrophyte drift dynamics near to coastlines. Acknowledging this variability is essential for further understanding of the ecological significance of allochthonous material arriving at shorelines, which should be integrated into future research and management of sandy-beach ecosystems.

Umbilical cord blood transplantation from HLA-identical siblings provides good results in children. These results support targeted efforts to bank family cord blood units that can be used for a sibling diagnosed with a disease which can be cured by allogeneic hematopoietic stem cell transplantation or for research that investigates the use of allogeneic or autologous cord blood cells. Over 500 patients transplanted with related cord blood units have been reported to the Eurocord registry with a 4-year overall survival of 91% for patients with non-malignant diseases and 56% for patients with malignant diseases. Main hematologic indications in children are leukemia, hemoglobinopathies or inherited hematologic, immunological or metabolic disorders. However, family-directed cord blood banking is not widely promoted; many cord blood units used in sibling transplantation have been obtained from private banks that do not meet the necessary criteria required to store these units. Marketing by private banks who predominantly store autologous cord blood units has created public confusion. There are very few current validated indications for autologous storage but some new indications might appear in the future. Little effort is devoted to provide unbiased information and to educate the public as to the distinction between the different types of banking, economic models and standards involved in such programs. In order to provide a better service for families in need, directed-family cord blood banking activities should be encouraged and closely monitored with common standards, and better information on current and future indications should be made available.

The (ab)normal-social-personality catena: Exploring The Journal of Abnormal and Social Psychology during the interwar years.

PubMed

Davidson, Ian J

2018-05-01

This article is a cocitation network analysis of The Journal of Abnormal and Social Psychology ( JASP ) from 1925 to 1942. The analysis was conducted to help shed light on the historical roots of the intellectual and institutional relationships among social, personality, and abnormal psychology. JASP was a main venue for the boundary work of early- to mid-twentieth-century American psychologists. One of the main goals of these various research communities was to appropriate psychoanalytic and sociological concepts into preferred methods and approaches that favored an individualistic, quantifiable, and ultimately normal subject. Five major research communities are identified using the citations, and historically contextualized: Community #1, Measuring Social Aspects; Community #2, Psychometrics; Community #3, Operationalizing Psychoanalysis; Community #4, Introversion Studies; and Community #5, Experimental Social Psychology. This analysis demonstrates how disciplinary psychologists, at least within JASP , were united by the work of delimiting their research from closely aligned fields studying the same concepts-even while psychologists' methodological commitments to experimentalism or psychological testing might have ostensibly divided them. Possible future research incorporating post-World War II research and dynamic networking approaches is recommended. (PsycINFO Database Record (c) 2018 APA, all rights reserved).

Ambient Pressure Test Rig Developed for Testing Oil-Free Bearings in Alternate Gases and Variable Pressures

NASA Technical Reports Server (NTRS)

Bauman, Steven W.

1990-01-01

The Oil-Free Turbomachinery research team at the NASA Glenn Research Center is conducting research to develop turbomachinery systems that utilize high-speed, high temperature foil (air) bearings that do not require an oil lubrication system. Such systems combine the most advanced foil bearings from industry with NASA-developed hightemperature solid-lubricant technology. New applications are being pursued, such as Oil- Free turbochargers, auxiliary power units, and turbine propulsion systems for aircraft. An Oil-Free business jet engine, for example, would be simpler, lighter, more reliable, and less costly to purchase and maintain than current engines. Another application is NASA's Prometheus mission, where gas bearings will be required for the closed-cycle turbine based power-conversion system of a nuclear power generator for deep space. To support these applications, Glenn's Oil-Free Turbomachinery research team developed the Ambient Pressure Test Rig. Using this facility, researchers can load and heat a bearing and evaluate its performance with reduced air pressure to simulate high altitude conditions. For the nuclear application, the test chamber can be purged with gases such as helium to study foil gas bearing operation in working fluids other than air.

The Cincinnati Observatory as a Research Instrument for Undergraduate Research

Abel, Nicholas; Regas, Dean; Flateau, Davin C.; Larrabee, Cliff

2016-06-01

The Cincinnati Observatory, founded in 1842, was the first public observatory in the Western Hemisphere. The history of Cincinnati is closely intertwined with the history of the Observatory, and with the history of science in the United States. Previous directors of the Observatory helped to create the National Weather Service, the Minor Planet Center, and the first astronomical journal in the U.S. The Cincinnati Observatory was internationally known in the late 19th century, with Jules Verne mentioning the Cincinnati Observatory in two of his books, and the Observatory now stands as a National Historic Landmark.No longer a research instrument, the Observatory is now a tool for promoting astronomy education to the general public. However, with the 11" and 16" refracting telescopes, the Observatory telescopes are very capable of collecting data to fuel undergraduate research projects. In this poster, we will discuss the history of the Observatory, types of student research projects capable with the Cincinnati Observatory, future plans, and preliminary results. The overall goal of this project is to produce a steady supply of undergraduate students collecting, analyzing, and interpreting data, and thereby introduce them to the techniques and methodology of an astronomer at an early stage of their academic career.

Spinal tuberculosis is the most common form of skeletal tuberculosis. However, there were limited data to evaluate the trend of spinal tuberculosis research. This study aims to investigate the trend of spinal tuberculosis research and compare the contribution of research from different countries and authors. Spinal tuberculosis-related publications from 1994 to 2015 were retrieved from the Web of Science database. Excel 2013, GraphPad Prism 5, and VOSviewer software were used to analyze the search results for number of publications, cited frequency, H-index, and country contributions. A total of 1558 papers were identified and were cited 16,152 times as of January 25, 2016. The United States accounted for 15.1% of the articles, 22.3% of the citations, and the highest H-index (33). China ranked third in total number of articles, fifth in citation frequency (815), and ranked seventh in H-index (13). The journal Spine (IF 2.297) had the highest number of publications. The author Jain A.K. has published the most papers in this field (20). The article titled "Tuberculosis of the spine: Controversies and a new challenge" was the most popular article and cited a total of 1138 times. The keyword "disease" was mentioned the most for 118 times and the word "bone fusion" was the latest hotspot by 2015. Literature growth in spinal tuberculosis is slowly expanding. Although publications from China are increasing, the quality of the articles still requires improvements. Meanwhile, the United States continues to be the largest contributor in the field of spinal tuberculosis. According to our bibliometric study, bone fusion may be an emerging topic within spinal tuberculosis research and is something that should be closely observed.

On January 14, 2004, the President of the United States announced a new vision for the United States civil space program. The Administrator of the National Aeronautics and Space Administration (NASA) has the responsibility to implement this new vision. The President also created a Presidential Commission 'to obtain recommendations concerning implementation of the new vision for space exploration.' The President's Commission recognized that achieving the exploration objectives would require significant technical innovation, research, and development in focal areas defined as 'enabling technologies.' Among the 17 enabling technologies identified for initial focus were advanced structures; advanced power and propulsion; closed-loop life support and habitability; extravehicular activity system; autonomous systems and robotics; scientific data collection and analysis; biomedical risk mitigation; and planetary in situ resource utilization. The Commission also recommended realignment of NASA Headquarters organizations to support the vision for space exploration. NASA has aggressively responded in its planning to support the vision for space exploration and with the current considerations of the findings and recommendations from the Presidential Commission. This presentation will examine the transformation and realignment activities to support the vision for space exploration that are underway in the microgravity materials science program. The heritage of the microgravity materials science program, in the context of residence within the organizational structure of the Office of Biological and Physical Research, and thematic and sub-discipline based research content areas, will be briefly examined as the starting point for the ongoing transformation. Overviews of future research directions will be presented and the status of organizational restructuring at NASA Headquarters, with respect to influences on the microgravity materials science program, will be discussed. Additional information is included in the original extended abstract.

Progressive Derechos in the Presence of Closed Upper-level Subtropical Anticyclones

NASA Astrophysics Data System (ADS)

Guastini, C.; Bosart, L. F.

2013-12-01

Progressive derechos are a type of long-lived mesoscale convective system that produces large swaths of wind damage. In contrast to their serial derecho counterparts, which form in association with extratropical cyclones, progressive derechos often occur in the presence of benign synoptic conditions on the poleward side of closed upper-level subtropical anticyclones. Forecasters have been known to struggle predicting progressive derechos with any certainty due to the common lack of large-scale support for severe weather in regimes dominated by anticyclonic conditions. This study will classify a group of days on which there was a closed upper-level anticyclone over the United States and a progressive derecho did not occur and a group of days on which there was a closed upper-level anticyclone over the United States and a progressive derecho did occur, examine the synoptic environments of the two groups, and identify derecho null cases. By analyzing the null cases, derecho failure modes will be determined, which will help forecaster situational awareness and reveal the science behind the environmental conditions necessary for, and detrimental to, derecho development. This presentation will include climatologies of both derechos and closed upper-level anticyclones over the United States for June, July, and August of the years 1994-2013 (the modern radar era). The presentation will also include closed anticyclone-relative composites of both derecho cases and derecho null cases. The composites will elucidate which conditions are necessary for, and which are detrimental to, derecho development. The hypothesis is that derecho failure days occur due either to the lack of a triggering mechanism or other phenomena working against convective development such as a strong capping inversion or transverse ageostrophic circulations around an upper-level jet creating subsidence in an otherwise favorable environment. A representative case study will be included to highlight a common derecho failure mode.

Controlling high-throughput manufacturing at the nano-scale

Cooper, Khershed P.

2013-09-01

Interest in nano-scale manufacturing research and development is growing. The reason is to accelerate the translation of discoveries and inventions of nanoscience and nanotechnology into products that would benefit industry, economy and society. Ongoing research in nanomanufacturing is focused primarily on developing novel nanofabrication techniques for a variety of applications—materials, energy, electronics, photonics, biomedical, etc. Our goal is to foster the development of high-throughput methods of fabricating nano-enabled products. Large-area parallel processing and highspeed continuous processing are high-throughput means for mass production. An example of large-area processing is step-and-repeat nanoimprinting, by which nanostructures are reproduced again and again over a large area, such as a 12 in wafer. Roll-to-roll processing is an example of continuous processing, by which it is possible to print and imprint multi-level nanostructures and nanodevices on a moving flexible substrate. The big pay-off is high-volume production and low unit cost. However, the anticipated cost benefits can only be realized if the increased production rate is accompanied by high yields of high quality products. To ensure product quality, we need to design and construct manufacturing systems such that the processes can be closely monitored and controlled. One approach is to bring cyber-physical systems (CPS) concepts to nanomanufacturing. CPS involves the control of a physical system such as manufacturing through modeling, computation, communication and control. Such a closely coupled system will involve in-situ metrology and closed-loop control of the physical processes guided by physics-based models and driven by appropriate instrumentation, sensing and actuation. This paper will discuss these ideas in the context of controlling high-throughput manufacturing at the nano-scale.

Endorsement of sexist ideology in Taiwan and the United States: social dominance orientation, right-wing authoritarianism, and deferential family norms.

PubMed

Lee, I-Ching

2013-01-01

Despite close relationships between men and women in daily lives, gender inequality is ubiquitous and often supported by sexist ideology. The understanding of potential bases of sexist ideology is thus important. According to Duckitt's dual-process model (2001), different worldviews may explain different types of sexist ideology. Individuals who hold a "competitive world" worldview tend to endorse group-based dominance. This lends itself to the endorsement of hostile sexism, because hostile sexism is an obvious form of male dominance. Conversely, individuals who hold a "dangerous world" worldview tend to adhere to social cohesion, collective security, and social traditions. This lends itself to the endorsement of benevolent sexism, because benevolent sexism values women who conform to gender norms. As predicted by Duckitt's model, research has shown that social dominance orientation, a general orientation towards the endorsement of group-based dominance, is closely associated with hostile sexism. Furthermore, right-wing authoritarianism, which measures adherence to social traditions, is closely associated with benevolent sexism. Due to the interdependent nature of gender relationships, the current research proposed that a relationship-based belief in hierarchy, deferential family norms, and norms depicting proper manners among family members should predict the endorsement of hostile and benevolent sexism, after controlling for social dominance orientation and right-wing authoritarianism. As predicted, according to student samples collected in Taiwan and the US, the endorsement of deferential family norms predicted the endorsement of hostile sexism and of benevolent sexism, respectively. In addition, among men and women, social dominance orientation predicted hostile sexism more strongly (as opposed to benevolent sexism), whereas right-wing authoritarianism predicted benevolent sexism more strongly (as opposed to hostile sexism). Implications regarding relationship norms, social dominance orientation, right-wing authoritarianism, and sexist ideology are discussed.

Closing the mental health gap in low-income settings by building research capacity: perspectives from Mozambique.

Neuropsychiatric disorders are the leading cause of disability worldwide, accounting for 22.7% of all years lived with disability. Despite this global burden, fewer than 25% of affected individuals ever access mental health treatment; in low-income settings, access is much lower, although nonallopathic interventions through traditional healers are common in many venues. Three main barriers to reducing the gap between individuals who need mental health treatment and those who have access to it include stigma and lack of awareness, limited material and human resources, and insufficient research capacity. We argue that investment in dissemination and implementation research is critical to face these barriers. Dissemination and implementation research can improve mental health care in low-income settings by facilitating the adaptation of effective treatment interventions to new settings, particularly when adapting specialist-led interventions developed in high-resource countries to settings with few, if any, mental health professionals. Emerging evidence from other low-income settings suggests that lay providers can be trained to detect mental disorders and deliver basic psychotherapeutic and psychopharmacological interventions when supervised by an expert. We describe a new North-South and South-South research partnership between Universidade Eduardo Mondlane (Mozambique), Columbia University (United States), Vanderbilt University (United States), and Universidade Federal de São Paulo (Brazil), to build research capacity in Mozambique and other Portuguese-speaking African countries. Mozambique has both the political commitment and available resources for mental health, but inadequate research capacity and workforce limits the country's ability to assess local needs, adapt and test interventions, and identify implementation strategies that can be used to effectively bring evidence-based mental health interventions to scale within the public sector. Global training and research partnerships are critical to building capacity, promoting bilateral learning between and among low- and high-income settings, ultimately reducing the mental health treatment gap worldwide.

Bamsey, Matthew; Schubert, Daniel; Zabel, Paul; Poulet, Lucie; Zeidler, Conrad

In 2011, the DLR Institute of Space Systems launched a research initiative called EDEN - Evolution and Design of Environmentally-closed Nutrition-Sources. The research initiative focuses on bioregenerative life support systems, especially greenhouse modules, and technologies for future crewed vehicles. The EDEN initiative comprises several projects with respect to space research, ground testing and spin-offs. In 2014, EDEN’s new laboratory officially opened. This new biological cleanroom laboratory comprises several plant growth chambers incorporating a number of novel controlled environment agriculture technologies. This laboratory will be the nucleus for a variety of plant cultivation experiments within closed environments. The utilized technologies are being advanced using the pull of space technology and include such items as stacked growth systems, PAR-specific LEDs, intracanopy lighting, aeroponic nutrient delivery systems and ion-selective nutrient sensors. The driver of maximizing biomass output per unit volume and energy has much application in future bioregenerative life support systems but can also provide benefit terrestrially. The EDEN laboratory also includes several specially constructed chambers for advancing models addressing the interaction between bioregenerative and physical-chemical life support systems. The EDEN team is presently developing designs for containerized greenhouse modules. One module is planned for deployment to the German Antarctic Station, Neumayer III. The shipping container based system will provide supplementation to the overwintering crew’s diet, provide psychological benefit while at the same time advancing the technology and operational readiness of harsh environment plant production systems. In addition to hardware development, the EDEN team has participated in several early phase designs such as for the ESA Greenhouse Module for Space System and for large-scale vertical farming. These studies often utilize the Institute of Space Systems Concurrent Engineering Facility.

On December 12-13, 2011, the United Nations Office for the Coordination of Humanitarian Affairs (OCHA) hosted a humanitarian policy and research conference on the theme of "Risk, Adaptation and Innovation in Humanitarian Action." The four sessions of the conference covered humanitarian action in a changing world, adaptation and innovation in humanitarian action, humanitarian action in protracted and violent conflict, and effective humanitarian action. This special report contains summaries of presentations in each session and the conclusions resulting from the discussions throughout. Through a process of open discussion, debate, and a closing survey, the conference participants identified four top priorities in humanitarian research for the coming years: evidence-driven humanitarian decision-making; accountability and transparency; risk and agility; and partnership. In addition to plans for a 2nd Annual Research and Policy conference in December of 2012, specific outcomes of the conference include a series of regional workshops in 2012 and 2013, launching with Asia, Africa and the Middle East; creation of Policy Working Groups (PWG) for each research priority identified; and a new flagship OCHA publication, to be launched in late 2012 or early 2013, which will share the progress made on the research priorities identified.

The organization of scientists and its relation to scientific productivity: Perceptions of Chinese stem cell researchers

PubMed Central

Zhang, Joy Yueyue

2013-01-01

Chinese government funding of R&D ranks third in the world. Yet China ranks only 17th in terms of scientific productivity per unit of investment. The author recently conducted fieldwork on the team structure of 22 Chinese stem cell research groups. Interview data suggest that although Chinese research groups closely resemble their international counter-parts in many respects, there are also significant differences which are perceived by interviewees to affect levels of scientific productivity. One characteristic of Chinese research teams is a common deficiency in middle-layer positions. This shortage of experienced professionals is perceived by scientists participating in this study to have led to two consequences. First, inexperienced student researchers often form the backbone of scientific teams in China, which leads to frequent interruptions of research and extended laboratory training. Second, research teams consist of a relatively small number of personnel. These structural features are seen to create excessive social boundaries, which impede the exchange of information and further worsens the segmentation of resources. This article engages the question of the extent to which interviewees’ local ‘embedded’ understandings of these difficulties may make a productive contribution to the analysis of the structural, and infra-structural, organization of Chinese professional bioscience teams.

Turbine design and application volumes 1, 2, and 3

NASA Technical Reports Server (NTRS)

Glassman, Arthur J. (Editor)

1994-01-01

NASA has an interest in turbines related primarily to aeronautics and space applications. Airbreathing turbine engines provide jet and turboshaft propulsion, as well as auxiliary power for aircraft. Propellant-driven turbines provide rocket propulsion and auxiliary power for spacecraft. Closed-cycle turbine engines using inert gases, organic fluids, and metal fluids have been studied for providing long-duration electric power for spacecraft. Other applications of interest for turbine engines include land-vehicle (cars, trucks, buses, trains, etc.) propulsion power and ground-based electrical power. In view of the turbine-system interest and efforts at Lewis Research Center, a course entitled 'Turbine Design and Application' was presented during 1968-69 as part of the In-house Graduate Study Program. The course was somewhat revised and again presented in 1972-73. Various aspects of turbine technology were covered including thermodynamic and fluid-dynamic concepts, fundamental turbine concepts, velocity diagrams, losses, blade aerodynamic design, blade cooling, mechanical design, operation, and performance. The notes written and used for the course have been revised and edited for publication. Such a publication can serve as a foundation for an introductory turbine course, a means for self-study, or a reference for selected topics. Any consistent set of units will satisfy the equations presented. Two commonly used consistent sets of units and constant values are given after the symbol definitions. These are the SI units and the U.S. customary units. A single set of equations covers both sets of units by including all constants required for the U.S. customary units and defining as unity those not required for the SI units. Three volumes are compiled into one.

Art and science in health care research: pushing at open doors or locked in institutions?

Research methods are usually dictated and driven by the research question. In the context of research in "closed" systems--for example, offender health settings--it is imperative that the research question takes into consideration the context in which the research is located. Conducting research that has action, transformation, and creativity at its heart is a significant challenge in closed cultures, for both the researcher and the researched. Using two exemplars, we question whether researchers should adopt a safe approach to researching these closed cultures and to what extent they should engage in methodological tensions and ethical dilemmas that provoke and support reflection on change. By reflecting on our previous research studies, we aim not so much to provide a definitive answer to this question but to suggest that researchers give careful consideration to the methods appropriate to both the context of the research and its purpose.

Lewandowski, Edward J.; Oriti, Salvatore M.; Schifer, Niholas A.

2016-01-01

Significant progress was made developing the Advanced Stirling Radioisotope Generator (ASRG) 140-W radioisotope power system. While the ASRG flight development project has ended, the hardware that was designed and built under the project is continuing to be tested to support future Stirling-based power system development. NASA Glenn Research Center recently completed the assembly of the ASRG Engineering Unit 2 (EU2). The ASRG EU2 consists of the first pair of Sunpower's Advanced Stirling Convertor E3 (ASC-E3) Stirling convertors mounted in an aluminum housing, and Lockheed Martin's Engineering Development Unit (EDU) 4 controller (a fourth-generation controller). The ASC-E3 convertors and Generator Housing Assembly (GHA) closely match the intended ASRG Qualification Unit flight design. A series of tests were conducted to characterize the EU2, its controller, and the convertors in the flight-like GHA. The GHA contained an argon cover gas for these tests. The tests included measurement of convertor, controller, and generator performance and efficiency; quantification of control authority of the controller; disturbance force measurement with varying piston phase and piston amplitude; and measurement of the effect of spacecraft direct current (DC) bus voltage on EU2 performance. The results of these tests are discussed and summarized, providing a basic understanding of EU2 characteristics and the performance and capability of the EDU 4 controller.

Auditory brain development in premature infants: the importance of early experience.

PubMed

McMahon, Erin; Wintermark, Pia; Lahav, Amir

2012-04-01

Preterm infants in the neonatal intensive care unit (NICU) often close their eyes in response to bright lights, but they cannot close their ears in response to loud sounds. The sudden transition from the womb to the overly noisy world of the NICU increases the vulnerability of these high-risk newborns. There is a growing concern that the excess noise typically experienced by NICU infants disrupts their growth and development, putting them at risk for hearing, language, and cognitive disabilities. Preterm neonates are especially sensitive to noise because their auditory system is at a critical period of neurodevelopment, and they are no longer shielded by maternal tissue. This paper discusses the developmental milestones of the auditory system and suggests ways to enhance the quality control and type of sounds delivered to NICU infants. We argue that positive auditory experience is essential for early brain maturation and may be a contributing factor for healthy neurodevelopment. Further research is needed to optimize the hospital environment for preterm newborns and to increase their potential to develop into healthy children. © 2012 New York Academy of Sciences.

Polar decomposition for attitude determination from vector observations

NASA Technical Reports Server (NTRS)

Bar-Itzhack, Itzhack Y.

1993-01-01

This work treats the problem of weighted least squares fitting of a 3D Euclidean-coordinate transformation matrix to a set of unit vectors measured in the reference and transformed coordinates. A closed-form analytic solution to the problem is re-derived. The fact that the solution is the closest orthogonal matrix to some matrix defined on the measured vectors and their weights is clearly demonstrated. Several known algorithms for computing the analytic closed form solution are considered. An algorithm is discussed which is based on the polar decomposition of matrices into the closest unitary matrix to the decomposed matrix and a Hermitian matrix. A somewhat longer improved algorithm is suggested too. A comparison of several algorithms is carried out using simulated data as well as real data from the Upper Atmosphere Research Satellite. The comparison is based on accuracy and time consumption. It is concluded that the algorithms based on polar decomposition yield a simple although somewhat less accurate solution. The precision of the latter algorithms increase with the number of the measured vectors and with the accuracy of their measurement.

Opportunistic toenail onychomycosis. The fungal colonization of an available nail unit space by non-dermatophytes is produced by the trauma of the closed shoe by an asymmetric gait or other trauma. A plausible theory.

PubMed

Zaias, N; Escovar, S X; Rebell, G

2014-08-01

Opportunistic onychomycosis is defined, when a non-dermatophyte mould is cultured from an abnormal nail unit in the absence of a dermatophyte. The presumption is that the mould has caused the abnormal clinical appearance of the nail unit, yet there are no data available to substantiate this claim. Reports have only identified the mould being recovered from the nail unit niche. A review of the published dermatologic literature describing toenail opportunistic onychomycosis by non-dermatophyte fungi has shown toenails with onycholysis, nail bed (NB) keratosis and nail plate surface abnormalities. The appearance of these clinical changes is indistinguishable from the diagnosis of the Asymmetric Gait Nail Unit Signs (AGNUS). AGNUS is produced by the friction of the closed shoe in patients with an asymmetric gait, resulting primarily from the ubiquitous uneven flat feet. Most commonly, species of Acremonium (Cephalosporium), Aspergillus, Fusarium, Scopulariopsis and rarely species of many different fungi genera are capable of surviving and reproducing in a keratinous environment and change the clinical appearance of the involved nail unit. AGNUS toenails predispose to the colonization by the non-dermatophyte opportunistic fungi but not by dermatophyte fungi. © 2014 European Academy of Dermatology and Venereology.

Whole genome sequencing and phylogenetic analysis of Bluetongue virus serotype 2 strains isolated in the Americas including a novel strain from the western United States.

Bluetongue is a potentially fatal arboviral disease of domestic and wild ruminants that is characterized by widespread edema and tissue necrosis. Bluetongue virus (BTV) serotypes 10, 11, 13, and 17 occur throughout much of the United States, whereas serotype 2 (BTV-2) was previously only detected in the southeastern United States. Since 1998, 10 other BTV serotypes have also been isolated from ruminants in the southeastern United States. In 2010, BTV-2 was identified in California for the first time, and preliminary sequence analysis indicated that the virus isolate was closely related to BTV strains circulating in the southeastern United States. In the current study, the whole genome sequence of the California strain of BTV-2 was compared with those of other BTV-2 strains in the Americas. The results of the analysis suggest co-circulation of genetically distinct viruses in the southeastern United States, and further suggest that the 2010 western isolate is closely related to southeastern strains of BTV. Although it remains uncertain as to how this novel virus was translocated to California, the findings of the current study underscore the need for ongoing surveillance of this economically important livestock disease.

Liver Injury from Herbal and Dietary Supplements

Navarro, Victor; Khan, Ikhlas; Björnsson, Einar; Seeff, Leonard B.; Serrano, Jose; Hoofnagle, Jay H.

2017-01-01

Herbal and dietary supplements (HDS) are used increasingly both in the United States and worldwide and HDS induced liver injury in the U.S. has increased proportionally. Current challenges in the diagnosis and management of HDS-induced liver injury were the focus of a 2-day research symposium sponsored by the American Association for the Study of Liver Disease and the National Institutes of Health. HDS-induced liver injury now accounts for 20% of cases of hepatotoxicity in the United States based on research data. The major implicated agents include anabolic steroids, green tea extract, and multi-ingredient nutritional supplements (MINS). Anabolic steroids marketed as bodybuilding supplements typically induce a prolonged cholestatic, but ultimately self-limiting liver injury that has a distinctive serum biochemical as well as histological phenotype. Green tea extract and many other products, in contrast, tend to cause an acute-hepatitis like injury. Currently, however, the majority of cases of HDS-associated liver injury are due to MINS, and the component responsible for the toxicity is usually unknown or can only be suspected. HDS-induced liver injury presents many clinical and research challenges, in diagnosis, identification of the responsible constituents, treatment and prevention. Also important are improvements in regulatory oversight of non-prescription products to guarantee their constituents and insure purity and safety. The confident identification of injurious ingredients within HDS will require strategic alignments among clinicians, chemists, and toxicologists. The ultimate goal should be to prohibit or more closely regulate potentially injurious ingredients and thus promote public safety. PMID:27677775

Stem cell treatments in China: rethinking the patient role in the global bio-economy.

PubMed

Chen, Haidan; Gottweis, Herbert

2013-05-01

The paper looks in detail at patients that were treated at one of the most discussed companies operating in the field of untried stem cell treatments, Beike Biotech of Shenzhen, China. Our data show that patients who had been treated at Beike Biotech view themselves as proactively pursuing treatment choices that are not available in their home countries. These patients typically come from a broad variety of countries: China, the United Kingdom, the United States, South Africa and Australia. Among the patients we interviewed there seemed to be both an awareness of the general risks involved in such experimental treatments and a readiness to accept those risks weighed against the possible benefits. We interpret this evidence as possibly reflecting the emergence of risk-taking patients as 'consumers' of medical options as well as the drive of patients to seek treatment options in the global arena, rather than being hindered by the ethical and regulatory constraints of their home countries. Further, we found that these patients tend to operate in more or less stable networks and groups in which they interact and cooperate closely and develop opinions and assessments of available treatment options for their ailments. These patients also perform a multiple role as patients, research subjects, and research funders because they are required to pay their way into treatment and research activities. This new social dynamics of patienthood has important implications for the ethical governance of stem cell treatments. © 2011 Blackwell Publishing Ltd.

Blaschke, Sabine; Müller, Gerhard A; Bergmann, Günther

2008-04-01

Configuration of the interdisciplinary emergency unit within the university clinic of Göttingen was successfully reorganized during the past two years. All emergencies except traumatologic, gynecologic and pediatric emergencies are treated within this functional unit which is guided by the center of internal medicine. It is organized in a three shift operation manner over a period of 24 hours. Due to a close interdisciplinary collaboration between different departments patients receive optimal diagnostic and therapeutic treatment within a short period of time. To improve processes within the emergency department a series of measures were taken including the -establishment of an intermediate care unit for unstable patients, setting up of special diagnostic and therapeutic units for the acute coronary syndrome as well as stroke, implementation of standardized clinical pathways, establishment of an electronic data processing network in close communication with all diagnostic entities, introduction of a quality assurance system and reduction of medical costs. Reorganization measures lead to a substantial optimization and acceleration of emergency proceedings and thus, provides optimal patient care around the clock. In addition, medical costs could clearly be reduced at the interface between preclinical and clinical emergency medicine.

Co-Authorship and Bibliographic Coupling Network Effects on Citations

PubMed Central

Biscaro, Claudio; Giupponi, Carlo

2014-01-01

This paper analyzes the effects of the co-authorship and bibliographic coupling networks on the citations received by scientific articles. It expands prior research that limited its focus on the position of co-authors and incorporates the effects of the use of knowledge sources within articles: references. By creating a network on the basis of shared references, we propose a way to understand whether an article bridges among extant strands of literature and infer the size of its research community and its embeddedness. Thus, we map onto the article – our unit of analysis – the metrics of authors' position in the co-authorship network and of the use of knowledge on which the scientific article is grounded. Specifically, we adopt centrality measures – degree, betweenneess, and closeness centrality – in the co-authorship network and degree, betweenness centrality and clustering coefficient in the bibliographic coupling and show their influence on the citations received in first two years after the year of publication. Findings show that authors' degree positively impacts citations. Also closeness centrality has a positive effect manifested only when the giant component is relevant. Author's betweenness centrality has instead a negative effect that persists until the giant component - largest component of the network in which all nodes can be linked by a path - is relevant. Moreover, articles that draw on fragmented strands of literature tend to be cited more, whereas the size of the scientific research community and the embeddedness of the article in a cohesive cluster of literature have no effect.

Closing the translation gap for justice requirements in international research.

PubMed

Pratt, Bridget; Zion, Deborah; Lwin, Khin Maung; Cheah, Phaik Yeong; Nosten, Francois; Loff, Bebe

2012-09-01

Bioethicists have long debated the content of sponsors and researchers' obligations of justice in international clinical research. However, there has been little empirical investigation as to whether and how obligations of responsiveness, ancillary care, post-trial benefits and research capacity strengthening are upheld in low- and middle-income country settings. In this paper, the authors argue that research ethics guidelines need to be more informed by international research practice. Practical guidance on how to fulfil these obligations is needed if research groups and other actors are to successfully translate them into practice because doing so is often a complicated, context-specific process. Case study research methods offer one avenue for collecting data to develop this guidance. The authors describe how such methods have been used in relation to the Shoklo Malaria Research Unit's vivax malaria treatment (VHX) trial (NCT01074905). Relying on the VHX trial example, the paper shows how information can be gathered from not only international clinical researchers but also trial participants, community advisory board members and research funder representatives in order to: (1) measure evidence of responsiveness, provision of ancillary care, access to post-trial benefits and research capacity strengthening in international clinical research; and (2) identify the contextual factors and roles and responsibilities that were instrumental in the fulfilment of these ethical obligations. Such empirical work is necessary to inform the articulation of obligations of justice in international research and to develop guidance on how to fulfil them in order to facilitate better adherence to guidelines' requirements.

Publication trends of research on diabetes mellitus and T cells (1997–2016): A 20-year bibliometric study

PubMed Central

He, Yifei; Chen, Rong; Zhou, Jingjing; Li, Ming

2017-01-01

Introduction Diabetes Mellitus (DM) is a huge burden for human health. Recent studies show the close relationship between DM and T cells. We investigated the trend in DM and T cells research. Methods Using the Web of Science database, we searched the publications on DM and T cells in 1997–2016, and studied the source data using bibliometric methodology. Excel 2016, GraphPad Prism 5, and VOSviewer software were used to analyze the publication trend in DM and T cells research. Results We found a total of 1077 publications with 38109 citations up to January 23, 2017. The highest contribution came from the United States, with 48.38% of the publications, 61.44% of the citations and the highest H-index (74). China had the 5th place for total publications, but ranked 11th both for citation frequency (604) and H-index (13). The inflection point of the global DM and T cells publications was in 2000. Journal of Immunology published the most related articles (164). Santamaria P. was the leading scholar in this field with the most publications (35). The keywords “regulatory T cell” and “autoimmune diabetes” were mentioned more than 300 times. Furthermore, type 2 (T2)DM, T cell immunoglobulin and mucin domain (TIM) and obesity are becoming popular research topics in this field. Conclusion The quantity of publications on DM and T cells grew rapidly around year 2000, but has relatively decreased recently. The United States had the leading position in global research. There was a discrepancy between productivity and quality of publications from China. Latest progress is most likely first published by the Journal of Immunology. Santamaria P., Roep B.O. and Peakman M. were the pioneer scholars in this field. Most researchers have focused on “regulatory T cell” and “autoimmune diabetes” research. In future, T2DM, TIM and obesity may be the popular areas. PMID:28926600

With the signing of the ITER Joint Implementing Agreement in November 2006, the ITER Members have now established the framework for construction of the project, and the ITER Organization has begun work at Cadarache. The review of recent progress in the physics basis for burning plasma experiments encompassed by the PIPB will be a valuable resource for the project and, in particular, for the current Design Review. The ITER design has been derived from a physics basis developed through experimental, modelling and theoretical work on the properties of tokamak plasmas and, in particular, on studies of burning plasma physics. The `ITER Physics Basis' (IPB), published in 1999, has been the reference for the projection methodologies for the design of ITER, but the IPB also highlighted several key issues which needed to be resolved to provide a robust basis for ITER operation. In the intervening period scientists of the ITER Participant Teams have addressed these issues intensively. The International Tokamak Physics Activity (ITPA) has provided an excellent forum for scientists involved in these studies, focusing their work on the high priority physics issues for ITER. Significant progress has been made in many of the issues identified in the IPB and this progress is discussed in depth in the PIPB. In this respect, the publication of the PIPB symbolizes the strong interest and enthusiasm of the plasma physics community for the success of the ITER project, which we all recognize as one of the great scientific challenges of the 21st century. I wish to emphasize my appreciation of the work of the ITPA Coordinating Committee members, who are listed below. Their support and encouragement for the preparation of the PIPB were fundamental to its completion. I am pleased to witness the extensive collaborations, the excellent working relationships and the free exchange of views that have been developed among scientists working on magnetic fusion, and I would particularly like to acknowledge the importance which they assign to ITER in their research. This close collaboration and the spirit of free discussion will be essential to the success of ITER. Finally, the PIPB identifies issues which remain in the projection of burning plasma performance to the ITER scale and in the control of burning plasmas. Continued R&D is therefore called for to reduce the uncertainties associated with these issues and to ensure the efficient operation and exploitation of ITER. It is important that the international fusion community maintains a high level of collaboration in the future to address these issues and to prepare the physics basis for ITER operation.

2003-01-01

Open-File Report 03-281 contains a digital geologic map database of the Elsinore 7.5’ quadrangle, Riverside County, California that includes: 1. ARC/INFO (Environmental Systems Research Institute, http://www.esri.com) version 7.2.1 coverages of the various elements of the geologic map. 2. A Postscript file to plot the geologic map on a topographic base, and containing a Correlation of Map Units diagram (CMU), a Description of Map Units (DMU), and an index map. 3. Portable Document Format (.pdf) files of: a. This Readme; includes in Appendix I, data contained in els_met.txt b. The same graphic as plotted in 2 above. Test plots have not produced precise 1:24,000-scale map sheets. Adobe Acrobat page size setting influences map scale. The Correlation of Map Units and Description of Map Units is in the editorial format of USGS Geologic Investigations Series (I-series) maps but has not been edited to comply with I-map standards. Within the geologic map data package, map units are identified by standard geologic map criteria such as formation-name, age, and lithology. Where known, grain size is indicated on the map by a subscripted letter or letters following the unit symbols as follows: lg, large boulders; b, boulder; g, gravel; a, arenaceous; s, silt; c, clay; e.g. Qyfa is a predominantly young alluvial fan deposit that is arenaceous. Multiple letters are used for more specific identification or for mixed units, e.g., Qfysa is a silty sand. In some cases, mixed units are indicated by a compound symbol; e.g., Qyf2sc. Even though this is an Open-File Report and includes the standard USGS Open-File disclaimer, the report closely adheres to the stratigraphic nomenclature of the U.S. Geological Survey. Descriptions of units can be obtained by viewing or plotting the .pdf file (3b above) or plotting the postscript file (2 above).

Increasing chronic disease research capacity in Guatemala through a mentoring program.

PubMed

Barnoya, Joaquin; Monzon, Jose C; Colditz, Graham A

2013-09-12

The Chronic Disease Research Fellowship Program (RFP) aims to build the research capacity of recent medical graduates to support the development of chronic disease control strategies. Guatemala is undergoing an epidemiologic transition. However, given the way universities and the health care system are structured, it lacks an environment that fosters research careers and generates the required knowledge to implement sound public health policies and clinical strategies. The RFP was implemented at the Cardiovascular Unit of Guatemala. This 4-year Program recruited two one-year fellows and provided funding to define a research topic, write a protocol and implement the research. Strong emphasis is placed on developing skills in knowledge translation and exchange to bridge the "know-do" gap. Close mentoring relationships between the Principal Investigator and former and current fellows are fostered through the Program. The mentoring Program has generated strategic data to support the implementation of sound chronic disease control strategies, mainly related to tobacco control. Results have been presented nationally and internationally. Research training has included principles of biostatistics and epidemiology, and a journal club. The Program is increasingly generating interest among medical graduates to pursue further research training abroad and is building local research capacity. Fellows and research assistants have created a research network in Guatemala and abroad. The main obstacle the Program faces is ensuring long-term sustainability. A mentoring program can lead to an increase in research interest and capacity in a low-income country with little research infrastructure.

Inside story on the legal challenge to EPA`s municipal waste combustor rule: The mouse that roared, Round 1

DOE Office of Scientific and Technical Information (OSTI.GOV)

Jenkins, L.S.

1997-12-01

An article in the Deseret News, one of two general circulation newspapers in Salt Lake City, Utah, dated December 13, 1996, reported that {open_quotes}David{close_quotes} took on {open_quotes}Goliath{close_quotes} and won. The article referred to the Davis County Solid Waste Management and Energy Recovery Special Service District`s (the {open_quotes}District{close_quotes}) victory on its challenge to the EPA`s municipal waste combustor rules. On December 6, 1996, the United States Court of Appeals for the District of Columbia Circuit ruled that the EPA violated the plain language of Section 129 of the Clean Air Act, when it wrote size categories for municipal waste combustors ({open_quotes}MWCs{close_quotes})more » based on aggregate plant capacity, rather than unit capacity. The District argued that Congress divided the universe of MWC units into two categories: those with unit capacities above 250 tons per day, and those with unit capacities equal to or less than 250 tons per day. The EPA, however, had set the dividing line at 248 tons per day aggregate plant capacity in its municipal waste combustor rule. The Court said this was wrong. The Deseret News report certainly echoed the feelings of the District. Those of you familiar with the EPA, the process of judicial review of administrative rule making, and the Biblical story of David and Goliath, however, will quickly see that this is not the best metaphor to describe what happened. When David slew Goliath, that was the end of Goliath. He didn`t get back up. Of course, that will not happen to the EPA in the Davis County case. Like an 800-pound gorilla, it will always get back up after being challenged by a mouse. This paper tells the story of the challenge to the MWC rule from the District`s perspective. The District has not been popular with either the EPA or many industry players. But, the District was faced with a real problem that, given the District`s location and the local economy, forced its hand in this case.« less

Regenerable Air Purification System for Gas-Phase Contaminant Control

NASA Technical Reports Server (NTRS)

Constantinescu, Ileana C.; Qi, Nan; LeVan, M. Douglas; Finn, Cory K.; Finn, John E.; Luna, Bernadette (Technical Monitor)

2000-01-01

A regenerable air purification system (RAPS) that uses water vapor to displace adsorbed contaminants from an. adsorbent column into a closed oxidation loop is under development through cooperative R&D between Vanderbilt University and NASA Ames Research Center. A unit based on this design can be used for removing trace gas-phase contaminants from spacecraft cabin air or from polluted process streams including incinerator exhaust. Recent work has focused on fabrication and operation of a RAPS breadboard at NASA Ames, and on measurement of adsorption isotherm data for several important organic compounds at Vanderbilt. These activities support the use and validation of RAPS modeling software also under development at Vanderbilt, which will in turn be used to construct a prototype system later in the project.

In the United States, racial/ethnic minority, rural, and low-income populations continue to experience suboptimal access to and quality of health care despite decades of recognition of health disparities and policy mandates to eliminate them. Many health care interventions that were designed to achieve health equity fall short because of gaps in knowledge and translation. We discuss these gaps and highlight innovative interventions that help address them, focusing on cardiovascular disease and cancer. We also provide recommendations for advancing the field of health equity and informing the implementation and evaluation of policies that target health disparities through improved access to care and quality of care.

The OTEC connection - Power from the sea

NASA Astrophysics Data System (ADS)

Petty, D.

1980-02-01

OTEC is discussed as a means of contributing to United States energy self-sufficiency. The technology involved in the conversion of ocean thermal gradients found in tropical regions to electricity transmittable by submarine cable is examined, with attention given to the operating principles of open- and closed-cycle Rankine engines and design considerations for the evaporators, condensers and heat exchangers. The environmental impact and economics of OTEC are considered, and Department of Energy research projects in areas of OTEC technology including heat transfer, biofouling, environmental assessment, underwater electrical transmission and mooring and test plants are indicated. It is pointed out that US islands presently offer excellent markets for early commercial OTEC plants, with Gulf Coast markets requiring further technology developments to be economically attractive.

Massive unseen companions to hot faint underluminous stars from SDSS (MUCHFUSS). Analysis of seven close subdwarf B binaries

The project Massive Unseen Companions to Hot Faint Underluminous Stars from SDSS (MUCHFUSS) aims at finding hot subdwarf stars with massive compact companions like massive white dwarfs (M > 1.0 M⊙), neutron stars or stellar mass black holes. The existence of such systems is predicted by binary evolution theory and recent discoveries indicate that they exist in our Galaxy. First results are presented for seven close binary sdBs with short orbital periods ranging from ≃ 0.21 d to 1.5 d. The atmospheric parameters of all objects are compatible with core helium-burning stars. The companions are most likely white dwarfs. In one case the companion could be shown to be a white dwarf by the absence of light-curve variations. However, in most cases late type main sequence stars cannot be firmly excluded. Comparing our small sample with the known population of close sdB binaries we show that our target selection method aiming at massive companions is efficient. The minimum companion masses of all binaries in our sample are high compared to the reference sample of known sdB binaries.

Air Force Research Laboratory Spacecraft Cryocooler Endurance Evaluation Facility Closing Report

NASA Astrophysics Data System (ADS)

Armstrong, J.; Martin, K. W.; Fraser, T.

2015-12-01

The Air Force Research Laboratory (AFRL) Spacecraft Component Thermal Research Group has been devoted to evaluating lifetime performance of space cryocooler technology for over twenty years. Long-life data is essential for confirming design lifetimes for space cryocoolers. Continuous operation in a simulated space environment is the only accepted method to test for degradation. AFRL has provided raw data and detailed evaluations to cryocooler developers for advancing the technology, correcting discovered deficiencies, and improving cryocooler designs. At AFRL, units of varying design and refrigeration cycles were instrumented in state-of-the-art experiment stands to provide spacelike conditions and were equipped with software data acquisition to track critical cryocooler operating parameters. This data allowed an assessment of the technology's ability to meet the desired lifetime and documented any long-term changes in performance. This paper will outline a final report of the various flight cryocoolers tested in our laboratory. The data summarized includes the seven cryocoolers tested during 2014-2015. These seven coolers have a combined total of 433,326 hours (49.5 years) of operation.
