Sample records for exchange program alternative

  1. Exchange program. Alternative options for purchase of environmentally friendly vehicles in Stockholm

    Energy Technology Data Exchange (ETDEWEB)

    Rader Olsson, Amy [Inregia AB, Stockholm (Sweden); Elam, N. [Atrax Energi AB, Goeteborg (Sweden)

    1999-11-01

    The city of Stockholm has decided to exchange 300 of its gasoline-driven vehicles for vehicles which emit fewer hazardous pollutants. A vehicle exchange program is being developed based on analyses which describe the driving patterns of Stockholm's vehicles, alternative fuel technology status, and financing alternatives. This report comprises the first two analyses, that of Stockholm's fleet driving patterns and alternative fuel technology options. The report has four major sections: * a technical analysis of the status of certain fuels and vehicles, including prognoses of availability in Sweden and the future development potential of each. (electric, biogas, ethanol, RME), * a driving study, which identifies those vehicles currently in Stockholm's fleet which could be exchanged for alternatively-fueled vehicles, * an analysis of five purchase package alternatives, and * a location analysis, which describes the accessibility of vehicles in each alternative to alternative fuel refueling facilities in Stockholm. Given current prices and availability of the alternative fuels and vehicles studied, we recommend a high share of electric and biogas vehicles for purchases during 1997. The cost-effectiveness of different vehicle types in their reduction of various hazardous pollutants, may however change dramatically as prices and availability of vehicles changes and the market for alternative fuels develops. Accessibility to alternative fuel refueling facilities is adequate in Stockholm, though not always ideal. To improve the accessibility of biogas vehicles further, we suggest a third biogas refueling facility in the city's northeastern area (Ropsten, Vaertahamnen). If MFO chooses to purchase a significant number of diesel passenger vehicles to be driven on RME; we propose that a facility in the northeastern area would improve accessibility more than another facility in southern Stockholm.

  2. Chemical exchange program analysis.

    Energy Technology Data Exchange (ETDEWEB)

    Waffelaert, Pascale

    2007-09-01

    As part of its EMS, Sandia performs an annual environmental aspects/impacts analysis. The purpose of this analysis is to identify the environmental aspects associated with Sandia's activities, products, and services and the potential environmental impacts associated with those aspects. Division and environmental programs established objectives and targets based on the environmental aspects associated with their operations. In 2007 the most significant aspect identified was Hazardous Materials (Use and Storage). The objective for Hazardous Materials (Use and Storage) was to improve chemical handling, storage, and on-site movement of hazardous materials. One of the targets supporting this objective was to develop an effective chemical exchange program, making a business case for it in FY07, and fully implementing a comprehensive chemical exchange program in FY08. A Chemical Exchange Program (CEP) team was formed to implement this target. The team consists of representatives from the Chemical Information System (CIS), Pollution Prevention (P2), the HWMF, Procurement and the Environmental Management System (EMS). The CEP Team performed benchmarking and conducted a life-cycle analysis of the current management of chemicals at SNL/NM and compared it to Chemical Exchange alternatives. Those alternatives are as follows: (1) Revive the 'Virtual' Chemical Exchange Program; (2) Re-implement a 'Physical' Chemical Exchange Program using a Chemical Information System; and (3) Transition to a Chemical Management Services System. The analysis and benchmarking study shows that the present management of chemicals at SNL/NM is significantly disjointed and a life-cycle or 'Cradle-to-Grave' approach to chemical management is needed. This approach must consider the purchasing and maintenance costs as well as the cost of ultimate disposal of the chemicals and materials. A chemical exchange is needed as a mechanism to re-apply chemicals on site. This

  5. Exchange Rate Dynamics under Alternative Optimal Interest Rate Rules

    OpenAIRE

    Binici, Mahir; Cheung, Yin-Wong

    2011-01-01

    We explore the role of interest rate policy in the exchange rate determination process. Specifically, we derive exchange rate equations from interest rate rules that are theoretically optimal under a few alternative settings. The exchange rate equation depends on its underlying interest rate rule and its performance could vary across evaluation criteria and sample periods. The exchange rate equation implied by the interest rate rule that allows for interest rate and inflation inertia under co...

    Full Text Available Donor-recipient ABO and/or HLA incompatibility used to lead to donor decline. Development of alternative transplantation programs enabled transplantation of incompatible couples. How did that influence couple characteristics? Between 2000 and 2014, 1232 living donor transplantations have been performed. In conventional and ABO-incompatible transplantation the willing donor becomes an actual donor for the intended recipient. In kidney-exchange and domino-donation the donor donates indirectly to the intended recipient. The relationship between the donor and intended recipient was studied. There were 935 conventional and 297 alternative program transplantations. There were 66 ABO-incompatible, 68 domino-paired, 62 kidney-exchange, and 104 altruistic donor transplantations. Waiting list recipients (n=101 were excluded as they did not bring a living donor. 1131 couples remained of whom 196 participated in alternative programs. Genetically unrelated donors (486 were primarily partners. Genetically related donors (645 were siblings, parents, children, and others. Compared to genetically related couples, almost three times as many genetically unrelated couples were incompatible and participated in alternative programs (P<0.001. 62% of couples were genetically related in the conventional donation program versus 32% in alternative programs (P<0.001. Patient and graft survival were not significantly different between recipient programs. Alternative donation programs increase the number of transplantations by enabling genetically unrelated donors to donate.

  12. Challenges, alternatives, and paths to sustainability for health information exchange efforts.

    Science.gov (United States)

    Vest, Joshua R; Campion, Thomas R; Kaushal, Rainu

    2013-12-01

    Health information exchange (HIE) is a promising approach to improving the cost and quality of healthcare. We sought to identify the strengths and weaknesses of organizational models to achieve exchange, and what can be done to ensure the sustainability and effectiveness of exchange efforts. We interviewed state and national health informatics policy experts (n = 17). Data were collected as part of an evaluation of the Health Care Efficiency and Affordability Law for New Yorkers (HEAL NY) program and included respondents from both the private and public sectors. Data were analyzed using a general inductive and comparative approach with open coding of themes. Interviewees generally viewed HIE as a public or societal good to be valued. However, they identified challenges with the regional health information organization (RHIO) model of facilitating exchange including: economics, organizational issues, and geography. RHIOs were contrasted against alternative methods of exchange such as Direct, enterprise HIE, and vendor-mediated exchange. HIE is a difficult undertaking due to political and economic reasons. Alternatives to the RHIO model have features that may be more attractive to participants, but may be of less public benefit. Using states as intermediaries and mandating exchange under public health law may avoid the challenges facing exchange efforts. Moving forward, policies will have to address the shortcomings of each HIE model to ensure information is effectively shared between providers to maximize health benefits.

    Kimmel, N. A.

    1984-01-01

    Four subscale solid rocket motor tests were conducted successfully to evaluate alternate nozzle liner, insulation, and exit cone structural overwrap components for possible application to the Space Shuttle Solid Rocket Motor (SRM) nozzle asasembly. The 10,000 lb propellant motor tests were simulated, as close as practical, the configuration and operational environment of the full scale SRM. Fifteen PAN based and three pitch based materials had no filler in the phenolic resin, four PAN based materials had carbon microballoons in the resin, and the rest of the materials had carbon powder in the resin. Three nozzle insulation materials were evaluated; an aluminum oxide silicon oxide ceramic fiber mat phenolic material with no resin filler and two E-glass fiber mat phenolic materials with no resin filler. It was concluded by MTI/WD (the fabricator and evaluator of the test nozzles) and NASA-MSFC that it was possible to design an alternate material full scale SRM nozzle assembly, which could provide an estimated 360 lb increased payload capability for Space Shuttle launches over that obtainable with the current qualified SRM design.

    2009-07-01

    The suitability of a high surface area graphite (HSAG) as proton exchange membrane fuel cell (PEMFC) catalyst support has been evaluated and compared with that of the most popular carbon black: the Vulcan XC72. It has been observed that Pt is arranged on the graphite surface resulting in different structures which depend on the catalysts synthesis conditions. The influence that the metal particle size and the metal-support interaction exert on the catalysts degradation rate is analyzed. Temperature programmed oxidation (TPO) under oxygen containing streams has been shown to be a useful method to assess the resistance of PEMFC catalysts to carbon corrosion. The synthesized Pt/HSAG catalysts have been evaluated in single cell tests in the cathode catalytic layer. The obtained results show that HSAG can be a promising alternative to the traditionally used Vulcan XC72 carbon black when suitable catalysts synthesis conditions are used. (author)

Alternative transportation programs such as employers programs, youth programs and institutional programs have environmental, economic, social and community benefits such as reduced emissions and greater transportation efficiency which lead to improved quality of life, health and sustainability of the transportation system. Organizations implement alternative transportation programs because of a commitment to; environmental responsibility, improving air quality, offering employee benefits, GHG reductions and corporate leadership. The programs are often initiated by large urban centres experiencing transportation-related problems such as congestion, air pollution or infrastructure capacity constraints. The U-Pass was presented as example of a very successful program that promotes change in behaviour at institutions to increase transit ridership. Telework also offers the opportunity of eliminating commutes. Ridematching is another key marketing tool employed by many organizations. The most successful programs are those with the greatest financial resources because sustained funding is necessary for program delivery, expansion and community acceptance. refs., tabs., figs.

  6. Dormancy programs as emerging antimetastasis therapeutic alternatives

    We recently published that the retinoid-responsive gene NR2F1 (nuclear receptor subfamily 2, group F, member 1) mediates postsurgical dormancy of local residual tumor cells and disseminated tumor cells. Importantly, the combination of azacytidine with retinoids induces dormancy of malignant tumor cells by reinstating the NR2F1-regulated gene program. These findings open the door to the development of strategies that may stop minimal residual disease from becoming life-threatening metastases. PMID:27308542

    Utilities around the nation are promoting residential conservation through a variety of program activities, ranging from customer education programs to financial incentive programs to direct installation programs. This report was undertaken to evaluate some of these alternative program designs, to compare their achievements against those of the RCS program, and to suggest program planning directions that seem most promising. Interviews with program managers were used to elucidate the rationale behind the alternative programs and to discuss program effectiveness. The experiences of nine utilities and one nonutility organization are reviewed. Program managers' opinions about RCS and their experiences with thirteen other programs are summarized. The effectiveness of the alternative program designs are compared and some implications for conservation program planning and implementation are highlighted.

    This report presents the status of the US Department of Energy`s alternative fuel vehicle demonstration and performance tracking programs being conducted in accordance with the Energy Policy and Conservation Act. These programs comprise the most comprehensive data collection effort ever undertaken on alternative transportation fuels and alternative fuel vehicles. The report summarizes tests and results from the fifth year. Electric vehicles are not included in these programs, and the annual report does not include information on them. Since the inception of the programs, great strides have been made in developing commercially viable alternative fuel vehicle technologies. However, as is the case in the commercialization of all new technologies, some performance problems have been experienced on vehicles involved in early demonstration efforts. Substantial improvements have been recorded in vehicle practicality, safety, and performance in real-world demonstrations. An aspect of particular interest is emissions output. Results from light duty alternative fuel vehicles have demonstrated superior inservice emissions performance. Heavy duty alternative fuel vehicles have demonstrated dramatic reductions in particulate emissions. However, emissions results from vehicles converted to run on alternative fuel have not been as promising. Although the technologies available today are commercially viable in some markets, further improvements in infrastructure and economics will result in greater market expansion. Information is included in this report on light and heavy duty vehicles, transit buses, vehicle conversions, safety, infrastructure support, vehicle availability, and information dissemination.

    The Hawaii Alternative Fuels Utilization Program originated as a five-year grant awarded by the US Department of Energy (USDOE) to the Hawaii Natural Energy Institute (HNEI) of the University of Hawaii at Manoa. The overall program included research and demonstration efforts aimed at encouraging and sustaining the use of alternative (i.e., substitutes for gasoline and diesel) ground transportation fuels in Hawaii. Originally, research aimed at overcoming technical impediments to the widespread adoption of alternative fuels was an important facet of this program. Demonstration activities centered on the use of methanol-based fuels in alternative fuel vehicles (AFVs). In the present phase, operations were expanded to include flexible fuel vehicles (FFVs) which can operate on M85 or regular unleaded gasoline or any combination of these two fuels. Additional demonstration work was accomplished in attempting to involve other elements of Hawaii in the promotion and use of alcohol fuels for ground transportation in Hawaii.

    An alternative separation of short-range exchange and correlation energies is used in the framework of second-order range-separated density-functional perturbation theory. This alternative separation was initially proposed by Toulouse and relies on a long-range-interacting wave function instead...... of the noninteracting Kohn-Sham one. When second-order corrections to the density are neglected, the energy expression reduces to a range-separated double-hybrid (RSDH) type of functional, RSDHf, where "f" stands for "full-range integrals" as the regular full-range interaction appears explicitly in the energy...... on the potential energy curves in the equilibrium region, improving the accuracy of binding energies and equilibrium bond distances when second-order perturbation theory is appropriate....

    Yaningsih, Indri; Wijayanta, Agung Tri

    2017-01-01

    The effects of twisted tapes using various wings with alternate axes on heat transfer, flow friction and thermal performance characteristics in a concentric tube heat exchanger are experimentally investigated. The influence of wing shape including triangle, rectangle and trapezoid are also studied. The experiments are performed using twisted tape with the constant wing-chord ratio (d/W) of 0.31, constant wing-span ratio (b/W) of 0.23 and constant twist ratio (y/W) of 3.8, over a Reynolds number range of 5800-18,500. The alternate axes are made by arranging each plane of twisted tape to 60-degree difference about the adjacent plane. The tests using the plain tube and tube with typical twisted tape were also conducted for a comparison. The results show that both heat transfer rate and friction factor associated with all twisted tape are consistently higher than those without twisted tape. Under the similar operating conditions, Nusselt number, friction factor as well as thermal performance factor given by the tape with alternate-axes and trapezoidal wings are higher than those given by the others. The maximum thermal performance factor of 1.44 is found with the use of twisted tape with alternate-axes and trapezoidal wings, where the heat transfer rate and friction factor increase to 1.91 and 5.2 times of those in the plain tube, respectively.

    The objective was to support administration and operation of the US-Russian Geoscience Student Exchange Program. During the grant period, thirty Russian geoscience students have completed the program. The students selected to participate in the program were recent graduates in geoscience from the leading Russian universities. On the students arrival in the US, the DOE grant provided funds for a one-week cultural orientation program through the facility of the Meridian House International, Washington DC. The students then traveled to Houston where they participated in a technical orientation in the offices of the petroleum company sponsors. Students spent two-semesters in US universities and a ten-week internship at the offices of the sponsoring oil companies or at the DOE facility in Bartlesville, Oklahoma. At the end of the program students returned to Russia where they are currently employed by the ministry and/or one of the US international oil companies. Some decided to continue their education and enrolled in US universities in Russian and the US. The list of participating students and their present status is attached.

  16. Assessment of breath-by-breath alveolar gas exchange: an alternative view of the respiratory cycle.

    Cettolo, V; Francescato, Maria Pia

    2015-09-01

    Breath-by-breath (BbB) determination of the O2 flux at alveolar level implies the identification of the start and end points of each respiratory cycle; Grønlund defined them as the times in two successive breaths showing equal expiratory gas fractions. Alternatively, the start and end points of each breath might be linked to the ratio between the exchangeable and non-exchangeable gases. The alternative algorithm is described and evaluated with respect to the algorithm proposed by Grønlund. Oxygen and carbon dioxide fractions, and ventilatory flow at the mouth were continuatively recorded in 20 subjects over 6 min at rest and during a cycloergometer exercise including 4 increasing intensities lasting 6 min each. Alveolar BbB oxygen uptake was calculated from the gas and flow traces by means of the two methods at stake. Total number of analysed breaths was 14,257. The data obtained with the two methods were close to the identity line (average slope 0.998 ± 0.004; R > 0.994; n > 334 in all subjects). Average difference between the O2 uptake data obtained by the two methods amounted to -0.27 ± 1.29 mL/min, whilst the standard deviation of the differences was 11.5 ± 4.6 mL/min. The relative percentage difference was independent from the O2 uptake and showed an average bias amongst subjects close to zero (-0.06 ± 0.15 %). The alternative timing of the respiratory cycle provided congruent O2 uptake data and made the identification of the start and end points of each breath more robust without introducing systematic errors.

    The adoption of sustainable land management strategies and practices that respond to current climate and human pressures requires both assessment tools that can lead to better informed decision-making and effective knowledge-exchange mechanisms that facilitate new learning and behavior change. We propose a learning-centered participatory approach that links land management assessment and knowledge exchange and integrates science-based data and stakeholder perspectives on both biophysical and socio-economic attributes. We outline a structured procedure for a transparent assessment of land management alternatives, tailored to dryland management, that is based on (1) principles of constructivism and social learning, (2) the participation of stakeholders throughout the whole assessment process, from design to implementation, and (3) the combination of site-specific indicators, identified by local stakeholders as relevant to their particular objectives and context conditions, and science-based indicators that represent ecosystem services of drylands worldwide. The proposed procedure follows a pattern of eliciting, challenging, and self-reviewing stakeholder perspectives that aims to facilitate learning. The difference between the initial baseline perspectives and the final self-reviewed stakeholder perspectives is used as a proxy of learning. We illustrate the potential of this methodology by its application to the assessment of land uses in a Mediterranean fire-prone area in East Spain. The approach may be applied to a variety of socio-ecological systems and decision-making and governance scales. Copyright © 2016 Elsevier Ltd. All rights reserved.

    2011-01-01

    What are the perceived benefits of a clinical exchange experience designed as part of a program to promote acceptance and use of evidence-based medicine (EBM) in naturopathic clinical practice? Nine faculty members participated in a focus group (n = 6) or a structured interview (n = 3) to assess experience in the program. Investigators independently analyzed transcribed notes for common experience themes. ANALYSIS AND INTERPRETATION: Six major themes emerged: integrating EBM into naturopathic clinical teaching, strengthening of professional relationships, exposure to clinical experiences outside the usual naturopathic scope, reaffirmation of naturopathic training and profession, observation of clinical and administrative resources and practices, and recommendations for future clinical exchanges. A clinical exchange experience was viewed as a favorable way to promote EBM appreciation within the complementary and alternative medicine educational community and to foster improved clinical experiences for faculty and their students and patients.

  4. Return Rates for Needle Exchange Programs: A Common Criticism Answered

    Directory of Open Access Journals (Sweden)

    Ksobiech Kate

    2004-04-01

    Full Text Available Abstract This study searched the available needle exchange program (NEP literature for return rate data. A total of 26 articles were found. The overall worldwide return rate was 90%, although this ranged from a low of 15% to a high of 112%. U.S. NEP return rates were gathered from only eight studies, indicating a clear need for more data, although U.S. return rates were comparable to those from NEPs outside of the U.S. One underlying assumption made by opponents of NEPs is that IDUs will not return needles to the distribution site, thereby potentially increasing the risk of health problems to the surrounding community from exposure to contaminated needles. This study's results suggest that NEPs are relatively successful in taking in used needles, although it is generally unclear where the needles were originally acquired, and if IDUs return their own needles, or are returning needles for a social network. Ways for AIDS Service Organizations to capitalize on these brief encounters with IDUs, as well as public policy implications of the findings, are discussed.

    The growing popularity of complementary and alternative medicine (CAM), of which estimated 38% of adults in the United States used in 2007, has engendered changes in medical school curricula to increase students' awareness of it. Exchange programs between conventional medical schools and CAM institutions are recognized as an effective method of interprofessional education. The exchange program between Albert Einstein College of Medicine (Einstein, Yeshiva University) and Pacific College of Oriental Medicine, New York campus (PCOM-NY) is in its fifth year and is part of a broader relationship between the schools encompassing research, clinical training, interinstitutional faculty and board appointments, and several educational activities. The Einstein/PCOM-NY student education exchange program is part of the Einstein Introduction to Clinical Medicine Program and involves students from Einstein learning about Chinese medicine through a lecture, the experience of having acupuncture, and a four-hour preceptorship at the PCOM outpatient clinic. The students from PCOM learn about allopathic medicine training through an orientation lecture, a two-and-a-half-hour dissection laboratory session along side Einstein student hosts, and a tour of the clinical skills center at the Einstein campus. In the 2011/2012 offering of the exchange program, the participating Einstein and PCOM students were surveyed to assess the educational outcomes. The data indicate that the exchange program was highly valued by all students and provided a unique learning experience. Survey responses from the Einstein students indicated the need for greater emphasis on referral information, which has been highlighted in the literature as an important medical curriculum integrative medicine competency.

    2002-10-01

    This ethnographic study, a component of another study that examined the lived experiences of a small group of pregnant teenagers, focused on the social and learning environment of an alternative school program for pregnant and parenting female adolescents, aged 13 to 19. Field notes, participant observation, group discussion, and informal conversational data were gathered over a 16-week period. Analysis of the data revealed four major themes: nurture and positive regard, sisterhood and belonging, mentoring and sense of family, and proactive learning environment and academic pride. The girls who attended the program developed close relationships with their peers and teachers. Many of them experienced academic success for the first time and reported that pregnancy and impending motherhood motivated them to do better in school. Recommendations for a more comprehensive school-based approach to meeting the needs of pregnant and parenting teens are made, particularly after the babies are born.

    2013-06-01

    This paper describes the development, implementation and evaluation of a semester-long exchange program between two Bachelor of Science in Nursing programs in the USA and Denmark. Nurses globally need to provide culturally sensitive care for an ethnically diverse population. Competencies on how to do so should start in basic nursing programs. A useful strategy is through immersion into another culture through an exchange program. Little is known about successful strategies for two-way or 360° exchange programs between schools from different countries. Guided by experiential learning theory, we developed an exchange program with the objective of enhancing nursing students' cultural competence through knowledge building, attitudes and behaviour development. Lessons learned and implications for educational institutions and policy are discussed. In internationalization of nursing education, an awareness of underlying cultural values regarding nursing competence and taking appropriate action are important for success. Other areas for a successful exchange program include matching of courses or content across schools, clear objectives and evaluation plans. Finally, flexibility and open communication are key components when setting up a 360° exchange program. © 2013 The Authors. International Nursing Review © 2013 International Council of Nurses.

    Jacobs, Fabian; Stegmann, Karsten; Siebeck, Matthias

    2014-03-04

    Universities are increasingly organizing international exchange programs to meet the requirements of growing globalisation in the field of health care. Analyses based on the programs' fundamental theoretical background are needed to confirm the learning value for participants. This study investigated the extent of sociocultural learning in an exchange program and how sociocultural learning affects the acquisition of domain-specific competencies. Sociocultural learning theories were applied to study the learning effect for German medical students from the LMU Munich, Munich, Germany, of participation in the medical exchange program with Jimma University, Jimma, Ethiopia. First, we performed a qualitative study consisting of interviews with five of the first program participants. The results were used to develop a questionnaire for the subsequent, quantitative study, in which 29 program participants and 23 matched controls performed self-assessments of competencies as defined in the Tuning Project for Health Professionals. The two interrelated studies were combined to answer three different research questions. The participants rated their competence significantly higher than the control group in the fields of doctor-patient relationships and communication in a medical context. Participant responses in the two interrelated studies supported the link between the findings and the suggested theoretical background. Overall, we found that the exchange program affected the areas of doctor-patient relationships and effective communication in a medical context. Vygotsky's sociocultural learning theory contributed to explaining the learning mechanisms of the exchange program.

    2014-06-01

    This work enters in the optics of the denitrification of a polluted water by two membrane techniques, the Donnan dialysis (DD) and the ion exchange membrane bioreactor (IEMB), using a conventional barrier, composed by an anion exchange membrane (AEM), and a hybrid barrier, where the AEM is combined to an anion exchange textile (AET). The effects of the hydrodynamic factor and the nature of the carbon source on the transfer and the reduction of nitrate ions were studied. The study results obtained through the DD showed the effectiveness of the hybrid barrier in the recovery and concentration of nitrate ions. This was also recorded during denitrification by the hybrid process, called the ion exchange membrane textile bioreactor (IEMTB), with a significant reduction of nitrates, compared to IEMB, due to the efficiency of the Pseudomonas aeruginosa biofilm formed at the surface of the AET. Here, the permselectivity of the membrane and the good bioreduction of the pollutants are no longer major conditions to the better performance of the process. The application of IEMTB in the denitrification of groundwater, having a nitrate concentration of 96.67 ppm, shows a total reduction of nitrate ions without changing the quality of the water. Indeed, the analysis of the recovered water, or yet the treated water, shows the absence of the bacterium by-products and concentrations in the nitrates and nitrites which are, respectively, equal to 0.02±0.01 ppm, and inferiors to the detection limit (<0.02 ppm).

    Enormously large amount of heat produced by human activities is now mostly wasted into the environment without use. To realize a sustainable society, it is important to develop practical solutions for waste heat recovery. Here, we demonstrate that a tubular thermoelectric device made of tilted multilayer of Bi(0.5)Sb(1.5)Te3/Ni provides a promising solution. The Bi(0.5)Sb(1.5)Te3/Ni tube allows tightly sealed fluid flow inside itself, and operates in analogy with the standard shell and tube heat exchanger. We show that it achieves perfect balance between efficient heat exchange and high-power generation with a heat transfer coefficient of 4.0 kW/m(2)K and a volume power density of 10 kW/m(3) using low-grade heat sources below 100°C. The Bi(0.5)Sb(1.5)Te3/Ni tube thus serves as a power generator and a heat exchanger within a single unit, which is advantageous for developing new cogeneration systems in factories, vessels, and automobiles where cooling of excess heat is routinely carried out.

  7. A clinical student exchange program organized by cardiothoracic department: feedback of participants.

    Science.gov (United States)

    Tirilomis, Theodor; Schoendube, Friedrich A

    2013-03-29

    The development of a student exchange program was an essential part of the cooperation between the Medical Schools of the University of Goettingen (Germany) and the University of Thrace in Alexandroupolis (Greece). The student exchange program started in 2008 and was performed once a year. The experiences of this program and the feedback of participants are presented. Although organized by the Dept. of Thoracic, Cardiac, and Vascular Surgery, the approach of the program was multidisciplinary. Participants also attended Continuous Medical Education activities primary addressed to physicians. At the end of the program, the participants evaluated the program anonymously. The educational units were rated via a 4-grade system. Additionally, it was possible to comment both positive and negative aspects of the program. Twenty-nine educational units were evaluated. The practical teaching units yielded a better result than the classical teaching units (93% of practical units were evaluated as "very good" vs. 74% of lectures/seminars). The Continuous Medical Education activities were evaluated less favorable (only 61% were evaluated as "very good"). The student exchange program enhanced effective teaching and learning. Courses supporting practical medical skills were extremely positive evaluated. Continuous Medical Education activities are not suitable for students and therefore, we do not include such an event anymore. Additionally, the program created an excellent forum for contact and communication between the students of the two universities.

  9. Bounded energy exchange as an alternative to the third law of thermodynamics

    Energy Technology Data Exchange (ETDEWEB)

    Heidrich, Matthias, E-mail: Heidrich_Matthias@web.de

    2016-10-15

    This paper introduces a postulate explicitly forbidding the extraction of an infinite amount of energy from a thermodynamic system. It also introduces the assumption that no measuring equipment is capable of detecting arbitrarily small energy exchanges. The Kelvin formulation of the second law is reinterpreted accordingly. Then statements related to both the unattainability version and the entropic version of the third law are derived. The value of any common thermodynamic potential of a one-component system at absolute zero of temperature is ascertained if some assumptions with regard to the state space can be made. The point of view is the phenomenological, macroscopic and non-statistical one of classical thermodynamics.

  12. Alternative extraction of alkaloid anticarcinogens from Brazilian "vinca rosea" using Ion exchange chromatography

    Directory of Open Access Journals (Sweden)

    Sérgio Freire de Carvalhaes

    Full Text Available Extracts in ethanol and ethanol-ammonia of dried leaves from Catharanthus roseus, gathered at Rio de Janeiro state, were adsorbed in a strongly acidic cation exchange resin with sulfonic acid group, using the finite bath method, resulting in an alkaloid retained fraction and an acidic and neutral unretained fraction. High Performance Liquid Chromatography showed the isolation of the alkaloid fraction to be highly selective and with good performance, with an absence of alkaloids in the unretained fraction, while the retained fraction presented 1,54-6,35 mg/g of vindoline and 0,12-0,91 mg/g of vinblastine, common for an alkaloid-rich concentrate, usually obtained by classic extraction with several steps using solvents.

    2007-01-01

    Two teachers from the town of San Pedro de Atacama, in the northern desert of the South American nation of Chile, arrive in Magdalena, New Mexico, Sunday, January 28, for a two-week visit that is part of a Sister Cities program sponsored by Associated Universities, Inc. (AUI), the nonprofit research corporation that operates the National Radio Astronomy Observatory (NRAO). They will be accompanied by their town's mayor. Myriam Nancy Rivera Mercado, Head of the high school in San Pedro, Gabriela Fernanda Rodriguez Moraleda, a tourism teacher there, and San Pedro Mayor Sandra Berna Martinez will begin a visit that includes classroom observations in the Magdalena schools, a reception hosted by the Magdalena Village Council, and a Mayor's Breakfast with Magdalena Mayor Jim Wolfe. They also will meet local residents, tour the Bosque del Apache National Wildlife Refuge with a second-grade class, visit an area ranch, tour the Very Large Array (VLA) radio telescope, and see Socorro's Community Arts Party. "These teachers will learn much about New Mexico, the United States, and our educational system, and will take this new knowledge back to their students and their community," said NRAO Education Officer Robyn Harrison. The visit is part of a Sister Cities program initiated and funded by AUI, which operates the NRAO for the U.S. National Science Foundation. Radio astronomy is a common link between San Pedro de Atacama and Magdalena. San Pedro is near the site of the Atacama Large Millimeter/submillimeter Array (ALMA), an international telescope project now under construction with funding by major partners in North America, Europe, and Japan. Magdalena is near the site of NRAO's VLA radio telescope. In Magdalena, the Village Council and Mayor Wolfe formalized their participation in the Sister Cities program last September, and San Pedro ratified the program in December. In San Pedro, the ceremony ratifying the agreement was attended by U.S. Ambassador to Chile Craig K

  14. THE EFFECT OF ERASMUS EXCHANGE PROGRAM ON ATTITUDES TOWARDS LEARNING ENGLISH FOREIGN LANGUAGE

    Directory of Open Access Journals (Sweden)

    Aylin GÜRLEK

    2016-04-01

    Full Text Available As a result of globalization the societies have got closer and there has occurred a link between countries and cultures in terms of trade, immigration and the exchange of information and ideas. Erasmus Exchange Program is another way of sharing cultures and information. Erasmus Exchange Program has paved the way for participants to think in different dimensions. Culture and language may be preferred as the selection of these dimensions. In this sense, sharing culture plays a major role among the objectives of Erasmus Program. In addition, culture may be represented with the use of EFL among the advantages of this program. Gardner (1985 states that the attitudes are important elements of learning process and suggests that the more positive attitudes a learner develop, the more achievement s/he gets during learning process. The study of Jenkins (2009 revealed that Erasmus Exchange Program helps participants to develop an appreciation towards the idea of being a non-native speaker of English in a multicultural environment. Put another way, English plays another major role and in this study the ultimate purpose has been determined to indicate changes in the attitudes of Erasmus Students at Kahramanmaraş Sütçü İmam University in Turkey towards learning EFL after Erasmus Exchange Program. 18 items in a questionnaire and a semi-structured interview have been conducted within the study. There are 65 participants in this study who studied in different European countries during an educational period. The results of the study indicate that living and studying in a multicultural environment either strengthened their already positive attitudes towards learning EFL or helped the participants to develop positive attitudes.

    Wingate, Lory Mitchell

    2017-01-01

    The National Radio Astronomy Observatory’s (NRAO) National and International Non-Traditional Exchange (NINE) Program teaches concepts of project management and systems engineering to chosen participants within a nine-week program held at NRAO in New Mexico. Participants are typically graduate level students or professionals. Participation in the NINE Program is through a competitive process. The program includes a hands-on service project designed to increase the participants knowledge of radio astronomy. The approach demonstrate clearly to the learner the positive net effects of following methodical approaches to achieving optimal science results.The NINE teaches participants important sustainable skills associated with constructing, operating and maintaining radio astronomy observatories. NINE Program learners are expected to return to their host sites and implement the program in their own location as a NINE Hub. This requires forming a committed relationship (through a formal Letter of Agreement), establishing a site location, and developing a program that takes into consideration the needs of the community they represent. The anticipated outcome of this program is worldwide partnerships with fast growing radio astronomy communities designed to facilitate the exchange of staff and the mentoring of under-represented groups of learners, thereby developing a strong pipeline of global talent to construct, operate and maintain radio astronomy observatories.

  18. Ion-Exchange Membrane Chromatography as an Alternative Method of Separation of Potato y Virus

    Directory of Open Access Journals (Sweden)

    2015-12-01

    Full Text Available Procedures of separation of virus particles from a plant material are multistage. Furthermore often they are difficult in terms of methodology and require use of expensive, highly specialist equipment and yield of separation is often low. The antigen obtained is often degraded and contains admixtures of other proteins. Therefore, generation of high quality and specificity antibodies based on such antigen is very difficult and quality of the antibodies has impact on reliability, sensitivity and unambiguity of results of immunodiagnostic tests (e.g. ELISA that are currently conventionally used to detect vegetable viruses. In this study three conventionally-performed methods of separation of potato virus Y (PVY were compared and a method of separation based on membrane chromatography, as an alternative separation technique, has been presented. It has been demonstrated that in proper process conditions good quality virus preparation can be obtained.

    To develop a durable proton-exchange membrane (PEM) for fuel-cell applications, a series of sulfonated poly(benzoxazole thioether sulfone)s (SPTESBOs) are designed and synthesized, with anticipated good dimensional stability (via acid-base cross linking), improved oxidative stability against free radicals (via incorporation of thioether groups), and enhanced inherent stability (via elimination of unstable end groups) of the backbone. The structures and the degree of sulfonation of the copolymers are characterized using Fourier-transform infrared spectroscopy, and nuclear magnetic resonance spectroscopy ({sup 1}H NMR and {sup 19}F NMR). The electrochemical stabilities of the monomers are examined using cyclic voltammetry in a typical three-electrode cell configuration. The physicochemical properties of the membranes vital to fuel-cell performance are also carefully evaluated under conditions relevant to fuel-cell operation, including chemical and thermal stability, proton conductivity, solubility in different solvents, water uptake, and swelling ratio. The new membranes exhibit low dimensional change at 25 C to 90 C and excellent thermal stability up to 250 C. Upon elimination of unstable end groups, the co-polymers display enhanced chemical resistance and oxidative stability in Fenton's test. Further, the SPTESBO-HFB-60 (HFB-60=hexafluorobenzene, 60 mol% sulfone) membrane displays comparable fuel-cell performance to that of an NRE 212 membrane at 80 C under fully humidified condition, suggesting that the new membranes have the potential to be more durable but less expensive for fuel-cell applications.

    Improvements were made to the Adaptive Maneuvering Logic (AML) computer program, a computer-generated, air-to-air combat opponent. The primary improvement was incorporating a measure of performance, the exchange ratio, defined as the statistical measure of number of enemy kills divided by number of friendly losses. This measure was used to test a new modification of the AML's combat tactics. When the new version of the AML competed against the old version, the new version won with an exchange ratio of 1.4.

    1.0 (iRER1.0, peak velocity (PV, heart rate (HR, and rate of perceived exertion (RPE. One-way repeated measure analysis variance was used, following Bonferroni post hoc test. Agreement between parameters was evaluated by Pearson correlation and dispersion error. There were no significant differences between iRER1.0 and VT2 parameters. The correlations were significant between iRER1.0 and VT2 parameters for absolute and relative VO2, speed, and HR (r=0.95; r=0.60; r=0.72; r=0.81, respectively. A small mean error (-0.2 km·h-1 was observed between iRER1.0 and VT2. However, it was also observed an overestimation trend for high speeds. In conclusion, iRER1.0 can be used as an alternative method to detect AT in long distance runners. However, its use is limited in runners with high aerobic capacity.

    Goldwater, Jason; Jardim, Juliette; Khan, Tasnuva; Chan, Karen

    2014-01-01

    Clinovations Government Solutions (CGS) was contracted in 2013 to conduct a mixed-methods evaluation of the District of Columbia (D.C.) Health Information Exchange (HIE) program as part of their Cooperative Agreement Grant funded by the Office of the National Coordinator in 2010. The evaluation was to focus on the progress of the HIE, how many providers and hospitals were participating in the program, and what benefits were being realized through the use of the HIE. During the course of the evaluation, the CGS team found that the use of the HIE to support public health reporting was one of its core elements. The D.C. HIE is one of 56 HIE that were funded out of the Cooperative Agreement program. The HIE program was managed by the District of Columbia Department of Health Care Finance (DHCF), which also manages the District of Columbia Medicaid Program. The program was initially designed to accomplish the following: developing state-level directories and enabling technical services for HIE within and across states; ensuring an effective model for governance and accountability; coordinating an integrated approach with Medicaid and public health; and developing or updating privacy and security requirements for HIE within and across state borders. As the evaluation progressed, the CGS team discovered that the relationship between the DHCF and the District of Columbia Department of Health (DOH) had become a cornerstone of the D.C. HIE program. The CGS team used a mixed-methods approach for the evaluation, including a review of documents developed by the DHCF in its HIE program, including its original application. We also conducted 10 key informant interviews and moderated two small-group discussions using a semistructured protocol; and we developed a survey that measured the use, satisfaction, and future sustainability of the HIE for over 200 providers within the District of Columbia. While the evaluation focused on the D.C. HIE program in its entirety, the results

    2015-11-01

    Syringe distribution policies continue to be debated in many jurisdictions throughout the USA. The Baltimore Needle and Syringe Exchange Program (NSP) operated under a 1-for-1 syringe exchange policy from its inception in 1994 through 1999, when it implemented a restrictive policy (2000-2004) that dictated less than 1-for-1 exchange for non-program syringes. Data were derived from the Baltimore NSP, which prospectively collected data on all client visits. We examined the impact of this restrictive policy on program-level output measures (i.e. distributed : returned syringe ratio, client volume) before, during and after the restrictive exchange policy. Through multiple logistic regression, we examined correlates of less than 1-for-1 exchange ratios at the client level before and during the restrictive exchange policy periods. During the restrictive policy period, the average annual program-level ratio of total syringes distributed : returned dropped from 0.99 to 0.88, with a low point of 0.85 in 2000. There were substantial decreases in the average number of syringes distributed, syringes returned, the total number of clients and new clients enrolling during the restrictive compared to the preceding period. During the restrictive period, 33 508 more syringes were returned to the needle exchange than were distributed. In the presence of other variables, correlates of less than 1-for-1 exchange ratio were being white, female and less than 30 years old. With fewer clean syringes in circulation, restrictive policies could increase the risk of exposure to HIV among Injection Drug Users (IDUs) and the broader community. The study provides evidence to the potentially harmful effects of such policies. © 2015 Australasian Professional Society on Alcohol and other Drugs.

    The transit bus program is designed to provide a comprehensive study of the alternative fuels currently used by the transit bus industry. The study focuses on the reliability, fuel economy, operating costs, and emissions of vehicles running on the various fuels and alternative fuel engines. The alternative fuels being tested are methanol, ethanol, biodiesel and natural gas. The alternative fuel buses in this program use the most common alternative fuel engines from the heavy-duty engine manufacturers. Data are collected in four categories: Bus and route descriptions; Bus operating data; Emissions data; and, Capital costs. The goal is to collect 18 months of data on each test bus. This report summarizes the interim results from the project to date. The report addresses performance and reliability, fuel economy, costs, and emissions of the busses in the program.

    Kanazawa Institute of Technology (KIT) supported a high school international exchange program between Komatsu Senior High School of Japan and Daejeon Science High School of South Korea through the delivery of a two-day pre-college engineering seminar in 2008. Students were asked to build stronger and more attractive bridges using as little balsa wood as possible. We delivered the course content through four pedagogical methods: the Plan-Do-Check-Action Cycle, hands-on exercises, cooperative learning, and presentations in English. Students also gained technical knowledge and an international way of thinking. This paper discusses the experience of supporting a high school international exchange program and the results of student feedback.

    Full Text Available Simple and quick hybridization procedures and ways to keep pollen grains viable for long periods are sought in plant breeding programs to provide greater work flexibility. The presentstudy was carried out to assess the efficiency of pollinations made shortly after flower emasculationand the viability of stored pollen from Eucalyptus camaldulensis and Eucalyptus urophylla clones cultivated in Northwestern Minas Gerais State. Controlled pollinations were carried out at zero, one,three, five and seven days after emasculation. Hybridization efficiency was assessed by thepercentage of viable fruits, number of seeds produced per fruit, percentage of viable seeds and also bycytological observation of the pollen development along the style. Flower buds from clones of the twospecies were collected close to anthesis to assess the viability of pollen grain storage. Pollen was thencollected and stored in a freezer (-18oC for 1, 2 and 3 months. Pollen assessed was carried out by invitro and in vivo germination tests. The efficiency of the pollinations varied with their delay and alsobetween species. The greatest pollination efficiency was obtained when they were carried out on thethird and fifth day after emasculation, but those performed simultaneously with emasculationproduced enough seeds to allow this practice in breeding programs. The decrease in pollen viabilitywith storage was not sufficiently significant to preclude the use of this procedure in artificialhybridization.

By deepening mutual understanding between Japan and China through this program, young Japanese and Chinese engineers can work toward their common goal of economic prosperity in their respective countries, while building partnerships based on mutual trust and respect.

  18. A computer program for designing fin-and-tube heat exchanger for EGR cooler application

    Science.gov (United States)

    Syaiful, Marwan, M. A.; Tandian, N. P.; Bae, M.

    2016-03-01

    EGR (exhaust gas recirculation) cooler is a kind of heat exchanger that is used to cool exhaust gas recirculation prior to be mixed with fresh air in an intake manifold of vehicle in order to obtain good reduction of NOxemissions. A fin-and-tube heat exchanger is more preferred as an EGR cooler than a shell-and-tube heat exchanger in this study due to its compactness. Manually designing many configurations of fin-and-tube heat exchanger for EGR cooler application consumes a lot of time and is high cost. Therefore, a computer aided design process of EGR cooler is required to overcome this problem. The EGR cooler design process was started by arranging the sequences of calculation algorithm in a computer program. A cooling media for this EGR cooler is air. The design is based on the effectiveness-number transfer unit (NTU) method. The EGR cooler design gives the geometry, heat transfer surface area, heat transfer coefficient and pressure drop of the EGR cooler. Comparison of the EGR cooler Nusselt number obtained in this study and that reported in literature shows less than 6.2% discrepancy.

    Full Text Available Spanish Educational Laws over the past years have been promoting the widespread use of English as the vehicle for teaching and learning in most curricular subjects. This trend is evincing new needs especially among higher education students. Consequently, Spanish Universities are looking for ways to provide international training involving global partnerships. The Polytechnic University of Madrid, Spain (UPM, and the University of British Columbia, Okanagan, Canada (UBCO have come together to offer opportunities for international collaboration and learning, thus facilitating virtual encounters among Spanish and Canadian students. The Language Exchange Program between the UPM and UBCO acts as a model for sustainability innovation in language and culture engagement as the students can interact with native speakers in communication tasks. This interdisciplinary initiative supports the latest methodological principles observed in the Common European Framework for Languages [1], such as autonomous and life-long learning, self-assessment and peer-assessment as well as the incorporation of new technologies to the learning process. Additionally the 'virtual' mobility is provided at no extra cost. This article presents the preliminary results of two virtual exchange programs that have been offering varied forms of study which are venue-independent, promoting collaborative work and cultural exchange.

    Injection drug use is an ongoing urban health crisis in China and one of the largest drivers of the transmission of HIV/AIDS. Sentinel surveillance sites in Yunnan province show upwards of 20% of injection drug users (IDUs) are HIV positive. Though the Ministry of Health has scaled-up needle exchange programs (NEPs), they have not received official government recognition nor have they been extensively evaluated to explore factors influencing their acceptability and feasibility. Using in-depth qualitative interviews conducted from February to July 2008 with 35 participants consisting of IDUs and other key stakeholders, we explored facilitators and barriers to accessing needle exchange programs in Kunming, the capital of Yunnan province. Content analysis was conducted to identify themes including attitudes toward NEPs and harm reduction, barriers to access, and suggestions for improvement. Themes that emerged included fears of breached confidentiality and police interference at the exchange sites and tensions between the public health and law enforcement perspective. Low levels of NEP-related knowledge and awareness were uniformly reported among interviewees. Suggestions to facilitate an increase in NEP acceptance included raising awareness of harm reduction and HIV more generally, offering services such as psychological counseling, job training and behavioral therapy at NEPs, and increasing communication between police, government, and public health officials. High rates of HIV infection among injection drug users in China have prompted rapid scale up of NEPs. Additional adaptations are necessary, however, to increase needle exchange use among injection drug users. This study finds that an urgent need to raise awareness of NEPs among policy makers and IDUs and act upon identified steps for developing social-structural interventions to create enabling environments that facilitate increased access to NEPs among injection drug users in Kunming.

    The Utility Nuclear Waste and Transportation Program of the Edison Electric Institute (EEI/UWASTE) has conducted reviews of the US DOE`s repository program through its Repository Information Exchange Team (RIET or Team). Eight such reviews have been conducted since 1985 covering topics that include repository program management and control; repository schedule; repository budget; quality assurance; site characterization; repository licensing; environmental issues; and institutional and public information activities. The utility industry has used these repository program reviews as a forum for providing DOE`s Office of Civilian Radioactive Waste Management (OCRWM) with comments on the direction of the repository program, advice for future actions regarding quality assurance activities and repository licensing, and suggestions for management and control of the Repository Program. The most significant recommendations made by the utility industry through the RIET are discussed along with any subsequent action by OCRWM in response to or subsequent to utility industry recommendations. The process used by the RIET to develop its recommendations to OCRWM regarding the repository program is also discussed.

    This program is a consortium of six research-based universities in Canada, Mexico, and the U.S (Michigan Tech, Buffalo, McGill, Waterloo, UNAM and Colima) funded by the Department of education in the US and equivalent organizations in Canada and Mexico as part of the NAFTA agreement. The focus area for the mobility program is mitigation of geological natural hazards in North America. The consortium universities will exchange students and faculty in several engineering and science disciplines (e.g. environmental engineering, civil engineering, geological engineering, social sciences and geology) involved in the study of natural geological hazards. Students in the social sciences also will be exchanged, recognizing that the solution of natural hazards problems involves critical political, social, and economic aspects. Students will be mobilized among the participating universities through one- to two-semester visits and up to 60 more students will be mobilized via short-term, intensive courses. Student activities will consist of three stages: intensive language training, natural hazards coursework, and professional or research internships with local industries, agencies or at the host university. In each of the next three years there will be a joint advanced volcanology class run via videoconferencing and a three week field trip to areas of volcanological interest in Canada, US and Mexico. The course and field trip foci for the next three years are: 2006: Megaeruptions/ LongValley and Yellowstone; 2007: Volcanic edifice failure/ Cascades and Western Canada 2008: Convergent plate Boundary Volcanism/ Mexican Volcanic Belt Although the six universities will have first access to the exchange we are constructing ways for other volcanology programs to share the teleconference courses and field trips.

    In response to the growing need to train a new generation of clinician scientists, a research program was developed to train medical students in integrative, complementary, and alternative medicine (ICAM) research early in their careers. A total of 25 students (100%) successfully completed a 10-week program. Students reported significantly increased levels of knowledge in all 7 integrative, complementary, and alternative medicine topics at the conclusion of the program. All students presented their work at one or more local research symposia. In addition, the average number of quality research outputs, which included manuscripts, awards, and abstracts presented at national and international meetings, was 1.5 per student, which exceeded benchmarks based on prior program outcomes. Results from this program may be useful when planning larger or longer-term projects aimed at attracting physicians who will become our next generation of academicians, researchers, and healers.

    France is a low-incidence country for tuberculosis (TB). Consequently screening is focused on high-risk populations, in particular migrants. The aim of this study was to evaluate the epidemiology of TB among international exchange students in the Department of Isère and the screening programs used. We carried out an organizational audit based on interviews with physicians involved in the management of TB in Isère. We conducted a retrospective descriptive study based on a case series of foreign students treated for TB from 2003 to 2013 inclusively. Forty-six international exchange students were treated for active TB during this time, representing an average incidence of 284/100,000. Two thirds of our studied population were Africans, 72% were asymptomatic at the time of screening. A quarter of our cohort developed TB after the initial screening. Thirty-one cases were confirmed bacteriologically, mainly through bronchoscopy. Outcome (radiological and clinical) on quadruple therapy was satisfactory in all patients. Two patients relapsed, one of them with multi-drug resistant TB. Our work confirms that international exchange students are a population at high risk of TB and that screening of this population is essential. The significant number of active TB cases diagnosed after the initial screening stresses the importance of diagnosis and follow up of patients with latent TB infection. Copyright © 2017 SPLF.

  1. Bureaucratic discretion and alternative teacher certification: understanding program variation in Missouri.

    Directory of Open Access Journals (Sweden)

    Ethan B. Heinen

    2007-06-01

    Full Text Available Alternative teacher certification literature has contributed significantly to our understanding of this approach to teacher preparation. However, this literature has more often than not treated alternative teacher certification programs (ATCPs as a black box, thus ignoring program heterogeneity. The present study examines how and why five ATCPs in Missouri have evolved in different ways. To understand this variation and its potential significance for researchers and practitioners, we use political science literature on bureaucratic discretion to understand programs' varied responses within the same state policy context. Using a multiple case study design, we present two key findings. First, external factors such as the state's regulatory approach, programs' relationships with school districts, and programs' relationship with external partners shape program coordinators' perceptions of their discretionary authority. Second, within an environment of limited regulation, programs responded to these external factors in ways that shaped programs in dramatically different ways. These approaches ranged from formal partnerships with large urban school districts and philanthropic funders to alternative certification programs that were at least partially blended with existing undergraduate and post baccalaureate teacher preparation programs. In our discussion, we explore how state attempts to widen the discretionary space between the rules may have allowed external interests (e.g., school districts, and external funders to backfill that space in ways that limit the potential for programs to provide high quality preparation experiences. This study explores these consequences and trade offs in order to inform policy makers and practitioners who are concerned with fostering innovative and creative ways to prepare high quality teachers.

    Background: Participation and to stay in a health program depends on many factors. One of these programs is Needle Exchange Program (NEP) in prisons. Objectives: The current study aimed to evaluate the retention of injecting drug prisoners and find the related factors in Iran. Patients and Methods: This cohort study analyzed data about injecting drug male prisoners who were participated in NEP in three Iranian prisons. Data was collected from October 2009 to June 2010. A proper approach of survival analyses including Kaplan-Meier method, Log-Rank test, and Cox Proportional Hazard Model were used to evaluate Injecting Drug Users (IDUs) retention in NEP and its determinants. Results: Out of 320 prisoners, 167 were from Isfahan Central Prison, 82 from Tehran-Ghezel-Hesar Prison, and 71 from Hamadan Central Prison. Two-hundred and fifty prisoners (78.4%) had history of drug injection; and drug injection was the most common choice for 115 persons (35.9%). Participants were followed up for 29 weeks, the mean (SD) time of retention in the program was 24.1 (0.6) weeks. There was a significant relationship between age, number of used needles per week, duration of addiction, age of addiction onset, as well as imprisonment age, main method of drug use, type of main using drug, Hepatitis B Virus (HBV) infection, job status, reason of arrestment, history of involvement in harm reduction programs, and the length of retention (P addiction (P = 0.048), and retention. Conclusions: Tattooing and longer duration of addiction were two important factors that significantly increased retention in the program. In contrast, history of using harm reduction services was the factor that decreased persistence. The risk of quitting the program may decrease about 68% in those who did not involve in harm reduction programs. PMID:26405681

    2013-09-12

    To assess the academic performance and experiences of local, international, and collaborative exchange students enrolled in a 4-year Australian bachelor of pharmacy degree program. Survey instruments exploring the demographics, background, and academic and cultural experiences of students during the program were administered in 2005 to students in all 4 years. Additionally, grades from each semester of the program for students (406 local, 70 international, 155 exchange) who graduated between 2002 and 2006 were analyzed retrospectively. The main differences found in the survey responses among the 3 groups were in students' motivations for choosing the degree program and school, with international and collaborative exchange students having put more thought into these decisions than local students. The average grades over the duration of the program were similar in all 3 demographic groups. However, local students slightly outperformed international students, particularly at the start of the year, whereas collaborative exchange students' grades mirrored those of local students during the 2 years prior to leaving their home country of Malaysia but more closely mirrored those of international students in the final 2 years after arriving on campus in Australia. Despite differences in academic backgrounds and culture, international and exchange students can perform well compared to local students in a bachelor of pharmacy program and were actually more satisfied than local students with the overall experience. Studying in a foreign country can negatively influence academic grades to a small extent and this is probably related to adjusting to the new environment.

    Rebecca A. Clothey

    2016-05-01

    Full Text Available This paper looks at an alternative curriculum model for study abroad designed specifically to address some of the needs of non-traditional students enrolled in an online education program. In order to meet the needs of non-traditional students and provide quality international programming for them, it is necessary first to understand their restraints to studying abroad, and then to design alternative educational models that can address these challenges. The paper describes the challenges of balancing the need to create quality international learning opportunities for education students, with the limitations faced by non-traditional online adult learners who have families and full-time jobs. It is based on an action research case study of two study abroad programs implemented for online students at a northeastern four-year research-one institution of higher education.

    To describe how Malagasy and Norwegian nursing students experience an educational exchange program in Madagascar. Previous studies show that nursing students participating in an educational exchange program enhanced their cultural knowledge and experienced personal growth. However, few studies have described two-way exchange programs, including experiences from both the hosts' and the guest students' perspectives. This study applies a descriptive qualitative design. Data were collected in 2015 by means of five semi-structured interviews with Malagasy students and two focus group interview sessions with Norwegian students. They were analysed using qualitative content analysis. The study was conducted in Madagascar. The data analyses revealed one main theme and two sub-themes related to the Malagasy and Norwegian nursing students' experiences. Main theme: complementary knowledge sharing; sub-themes: (1) learning from each other and (2) challenges of working together. The findings indicate that both the Malagasy and Norwegian nursing students experienced the exchange program as valuable and essential in exchanging knowledge. They also highlighted challenges, linked mainly to language barriers and the lack of available resources. Copyright © 2016 Elsevier Ltd. All rights reserved.

    2014-12-01

    The paper deals with the main problems of Russian energy system development that proves necessary to provide educational programs in the field of renewable and alternative energy. In the paper the process of curricula development and defining teaching techniques on the basis of expert opinion evaluation is defined, and the competence model for renewable and alternative energy processing master students is suggested. On the basis of a distributed questionnaire and in-depth interviews, the data for statistical analysis was obtained. On the basis of this data, an optimization of curricula structure was performed, and three models of a structure for optimizing teaching techniques were developed. The suggested educational program structure which was adopted by employers is presented in the paper. The findings include quantitatively estimated importance of systemic thinking and professional skills and knowledge as basic competences of a masters' program graduate; statistically estimated necessity of practice-based learning approach; and optimization models for structuring curricula in renewable and alternative energy processing. These findings allow the establishment of a platform for the development of educational programs.

    Site-specific recombinase mediated cassette exchange (RMCE) enables the transfer of the gene of interest (GOI) into pre-selected genomic locations with defined expression properties. For the generation of recombinant production cell lines, this has the advantage that screening for high transcription rates at the genome integration site would be required only once, with the possibility to reuse the selected site for new products. Here, we describe a strategy that aims at the selection of transcriptionally active genome integration sites in Chinese Hamster Ovary (CHO) cells by using alternate start codons in the surface reporter protein CD4, in combination with FACS sorting for high expressers. The alternate start codon reduces the translation initiation efficiency and allows sorting for CHO cells with the highest transcription rates, while RMCE enables the subsequent exchange of the CD4 against the GOI. We have shown that sorted cell pools with the CD4 reporter gene containing the alternate start codon CTG lead to higher GFP signals and higher antibody titers upon RMCE as compared to cell pools containing the ATG start codon of the CD4 reporter. Despite the absence of any subcloning step, the final cell pool contained the CD4 gene in a single genome integration site. © 2017 Wiley Periodicals, Inc.

  19. Conserved alternative and antisense transcripts at the programmed cell death 2 locus

    2007-01-01

    Full Text Available Abstract Background The programmed cell death 2 (Pdcd2 gene on mouse chromosome 17 was evaluated as a member of a highly conserved synteny, a candidate for an imprinted locus, and a candidate for the Hybrid sterility 1 (Hst1 gene. Results New mouse transcripts were identified at this locus: an alternative Pdcd2 mRNA skipping the last two coding exons and two classes of antisense RNAs. One class of the antisense RNA overlaps the alternative exon and the other the entire Pdcd2 gene. The antisense RNAs are alternative transcripts of the neighboring TATA-binding protein gene (Tbp that are located mainly in the cell nucleus. Analogous alternative PDCD2 forms truncating the C-terminal domain were also detected in human and chicken. Alternative transcripts of the chicken PDCD2 and TBP genes also overlap. No correlation in the transcription of the alternative and overlapping mRNAs was detected. Allelic sequencing and transcription studies did not reveal any support for the candidacy of Pdcd2 for Hst1. No correlated expression of Pdcd2 with the other two genes of the highly conserved synteny was observed. Pdcd2, Chd1, and four other genes from this region were not imprinted in the embryo. Conclusion The conservation of alternative transcription of the Pdcd2 gene in mouse, human and chicken suggests the biological importance of such truncated protein. The biological function of the alternative PDCD2 is likely to be opposite to that of the constitutive form. The ratio of the constitutive and alternative Pdcd2 mRNAs differs in the tissues, suggesting a developmental role. The identified Tbp-alternative Pdcd2-antisense transcripts may interfere with the transcription of the Pdcd2 gene, as they are transcribed at a comparable level. The conservation of the Pdcd2/Tbp sense-antisense overlap in the mouse and chicken points out its biological relevance. Our results also suggest that some cDNAs in databases labeled as noncoding are incomplete alternative cDNAs of

    Computerized cognitive behavioral therapy (cCBT) programs have been shown to be both acceptable and effective with youth. However, their use with more vulnerable youth, such as early school leavers, remains relatively unstudied. This study explored student and staff attitudes toward the use of cCBT in an alternative education setting. Student and staff needs were assessed using the Requirements development approach (Van Velsen, Wentzel, & Van Gemert-Pijnen, 2013). An online staff survey (n = 16) was conducted to provide information on the context of delivery, and stakeholder requirements were further explored in four student workshops (n = 32) and staff group discussions (n = 12). Students' requirements in relation to program look and feel were reflective of issues with literacy and concentration. Activity- rather than text-based programs were considered easier to learn from, whereas attractive design with features such as connecting with others were thought necessary to keep young people engaged. Students wanted to learn practical skills on improving their mental health and well-being, using content that is positive, encouraging, and credible and that can be tailored to individual needs. Anonymity and voluntary participation were considered essential when delivering cCBT in the context of alternative education, as well as additional access from home to ensure timeliness of support. Staff required both flexibility and careful planning and timetabling in order to deliver cCBT in the alternative education setting and to support student engagement. The findings provide novel insight into the needs and preferences of vulnerable youth, with important implications for the implementation of computerized mental health programs in alternative education settings. A better understanding of user needs and preferences is critical for improving the uptake and impact of e-mental health resources.

    The U.S. Department of Energy (DOE) is currently conducting a Nonproliferation Alternative Systems Assessment Program (NASAP) to identify nuclear fuel cycle options that pose inherently low risks of nuclear weapons proliferation while retaining the major benefits of nuclear energy. During FY 1978, the desirability and effectiveness of alternative nuclear fuel cycles will be examined in terms of the cycles' proliferation risk, technical feasibility, economic feasibility, and potential environmental and health effects. Final recommendations based on these several assessments may be made late in FY 1978. Carefully planned, highly efficient research strategies will be required to complete the necessary assessments within the anticipated time frame. The purpose of this report is to identify and evaluate alternative strategies for organizing the environmental and health (E and H) effects assessment. Following a brief review of the range of alternative nuclear fuel cycles under consideration, the report consists of three major sections. A discussion of what presently appear to be the most significant environmental and health issues associated with alternative fuel cycles is presented in Section 2. Major choice points in developing an effective assessment strategy, and the range of options available at each, are identified and evaluated in Section 3. Section 4 summarizes conclusions and recommends courses of action for proceeding with the detailed NASAP environmental assessment.

    GAUSTEQ was a Germany-U.S. exchange program in nuclear theory whose purpose was to focus research efforts on QCD studies of hadrons and nuclei, centered around the current and future research programs of Jefferson Lab and the Gesellschaft fur Schwerionenforschung (GSI) in Germany. GAUSTEQ provided travel support for theoretical physicists at US institutions conducting collaborative research with physicists in Germany. GSI (with its Darmstadt and Helmholtz Institute Mainz braches) served as the German “hub” for visits of U.S. physicists, while Jefferson Lab served as the corresponding “hub” for visits of German physicists visiting U.S. institutions through the reciprocal GUSTEHP (German-US Theory Exchange in Hadron Physics) program. GAUSTEQ was funded by the Office of Nuclear Physics of the U.S. Department of Energy, under Contract No.DE-SC0006758 and officially managed through Old Dominion University in Norfolk, Virginia. The program ran between 2011 and 2015.

    Development of improved communication and education strategies is important to make alternatives to the use of animals, and the broad range of applications of the 3Rs concept better known and understood by different audiences. For this purpose, the Center for Alternatives to Animal Testing in Europe (CAAT-Europe) together with the Transatlantic Think Tank for Toxicology (t(4)) hosted a three-day workshop on "Teaching Alternative Methods to Animal Experimentation". A compilation of the recommendations by a group of international specialists in the field is summarized in this report. Initially, the workshop participants identified the different audience groups to be addressed and also the communication media that may be used. The main outcome of the workshop was a framework for a comprehensive educational program. The modular structure of the teaching program presented here allows adaptation to different audiences with their specific needs; different time schedules can be easily accommodated on this basis. The topics cover the 3Rs principle, basic research, toxicological applications, method development and validation, regulatory aspects, case studies and ethical aspects of 3Rs approaches. This expert consortium agreed to generating teaching materials covering all modules and providing them in an open access online repository.

    Until the early 2000s, there was only one needle exchange program (NEP) offered in Mexico. In 2004, the second Mexican NEP opened in Tijuana, but its utilization has not been studied. We studied predictors of initiating NEP during its early expansion in Tijuana, Mexico. From April 2006 to April 2007, people who inject drugs (PWID) residing in Tijuana who had injected within the last month were recruited using respondent-driven sampling. Weighted Poisson regression incorporating generalized estimating equations was used to identify predictors of initiating NEP, while accounting for correlation between recruiter and recruits. NEP uptake increased from 20% at baseline to 59% after 6 months. Among a subsample of PWID not accessing NEP at baseline (n = 480), 83% were male and median age was 37 years (Interquartile Range: 32-43). At baseline, 4.4% were HIV-infected and 5.9% had syphilis titers >1:8. In multivariate models, factors associated with NEP initiation (p 2500 pesos/month (ARR: .66); and reporting needle sharing (ARR: .71). Uptake of NEP expansion in Tijuana was vigorous among PWID. We identified a range of factors that influenced the likelihood of NEP initiation, including police interaction. These findings have important implications for the scale-up of NEP in Mexico. © American Academy of Addiction Psychiatry.

    Interoperability and data-exchange are critical for the survival of government information management programs. E-government initiatives are transforming the way the government interacts with the public. More information is to be made available through web-enabled technologies. Programs such as the NASA's Scientific and Technical Information (STI) Program Office are tasked to find more effective ways to disseminate information to the public. The NASA STI Program is an agency-wide program charged with gathering, organizing, storing, and disseminating NASA-produced information for research and public use. The program is investigating the use of a new protocol called the Open Archives Initiative (OAI) as a means to improve data interoperability and data collection. OAI promotes the use of the OAI harvesting protocol as a simple way for data sharing among repositories. In two separate initiatives, the STI Program is implementing OAI In collaboration with the Air Force, Department of Energy, and Old Dominion University, the NASA STI Program has funded research on implementing the OAI to exchange data between the three organizations. The second initiative is the deployment of OAI for the NASA technical report server (TRS) environment. The NASA TRS environment is comprised of distributed technical report servers with a centralized search interface. This paper focuses on the implementation of OAI to promote interoperability among diverse data repositories.

    A novel exon microarray format that probes gene expression with single exon resolution was employed to elucidate critical features of a vertebrate muscle alternative splicing program. A dataset of 56 microarray-defined, muscle-enriched exons and their flanking introns were examined computationally in order to investigate coordination of the muscle splicing program. Candidate intron regulatory motifs were required to meet several stringent criteria: significant over-representation near muscle-enriched exons, correlation with muscle expression, and phylogenetic conservation among genomes of several vertebrate orders. Three classes of regulatory motifs were identified in the proximal downstream intron, within 200nt of the target exons: UGCAUG, a specific binding site for Fox-1 related splicing factors; ACUAAC, a novel branchpoint-like element; and UG-/UGC-rich elements characteristic of binding sites for CELF splicing factors. UGCAUG was remarkably enriched, being present in nearly one-half of all cases. These studies suggest that Fox and CELF splicing factors play a major role in enforcing the muscle-specific alternative splicing program, facilitating expression of a set of unique isoforms of cytoskeletal proteins that are critical to muscle cell differentiation. Supplementary materials: There are four supplementary tables and one supplementary figure. The tables provide additional detailed information concerning the muscle-enriched datasets, and about over-represented oligonucleotide sequences in the flanking introns. The supplementary figure shows RT-PCR data confirming the muscle-enriched expression of exons predicted from the microarray analysis.

    Highlights: • Motivating alternative RHR heat exchanger tube-side flow path and determining required capacity. • Calculate NSSS and containment response during 24-h SBO for Chinshan BWR-4 plant. • RETRAN and GOTHIC models are developed for NSSS and containment, respectively. • Safety relief valve blowdown flow and energy to drywell are generated by RETRAN. • Analyses are performed with and without reactor depressurization, respectively. - Abstract: The extended Station Blackout (SBO) of 24 h has been analyzed with respect to the containment response, in particular the suppression pool temperature response, for the Chinshan BWR-4 plant of MARK-I containment. The Chinshan plant, owned by Taiwan Power Company, has twin units with rated core thermal power of 1840 MW each. The analysis is aimed at determining the required alternative cooling water flow capacity for the residual heat removal (RHR) heat exchanger when its tube-side sea water cooling flow path is blocked, due to some reason such as earthquake or tsunami, and is switched to the alternative raw water source. Energy will be dissipated to the suppression pool through safety relief valves (SRVs) of the main steam lines during SBO. The RETRAN model is used to calculate the Nuclear Steam Supply System (NSSS) response and generate the SRV blowdown conditions, including SRV pressure, enthalpy, and mass flow rate. These conditions are then used as the time-dependent boundary conditions for the GOTHIC code to calculate the containment pressure and temperature response. The shaft seals of the two recirculation pumps are conservatively assumed to fail due to loss of seal cooling and a total leakage flow rate of 36 gpm to the drywell is included in the GOTHIC model. Based on the given SRV blowdown conditions, the GOTHIC containment calculation is performed several times, through the adjustment of the heat transfer rate of the RHR heat exchanger, until the criterion that the maximum suppression pool temperature

    Full Text Available An alternative optimization technique via multiobjective programming for constrained optimization problems with interval-valued objectives has been proposed. Reduction of interval objective functions to those of noninterval (crisp one is the main ingredient of the proposed technique. At first, the significance of interval-valued objective functions along with the meaning of interval-valued solutions of the proposed problem has been explained graphically. Generally, the proposed problems have infinitely many compromise solutions. The objective is to obtain one of such solutions with higher accuracy and lower computational effort. Adequate number of numerical examples has been solved in support of this technique.

    Recombinant measles virus nucleoproteins (rMeV N) and fusion (F) proteins were characterized as major antigenic proteins expressed in insect cells mediated by recombinant baculoviruses (rBVs). Band intensities were analyzed by Western blotting to recognize IgG and IgM antibodies against the rMeV N and F proteins in human sera and cerebrospinal fluids (CSFs) from patients with measles infections. Positive results from the blots using the rMeV N were consistent with the results of enzyme-linked immunosorbent assays (ELISAs) in which whole viral proteins were used as antigens. Human sera and CSFs reacted more strongly with the rMeV N than with the rMeV F proteins prepared in an identical expression system. For efficient and reliable purification, ion-exchange chromatography using Source Q anion resin was applied, and high-purity rMeV N protein was harvested. To characterize the similarity with the native viral protein to purified N protein, structural mimicry of purified recombinant proteins with intact rMeV N was shown through transmission electron microscopy, and the truncation and the phosphorylation status of the expressed protein were analyzed. These results suggest that the rMeV N purified by ion-exchange chromatography has features similar to those of naïve N including a self-assembled structure, phosphorylation and antigenic function. Thus, these expression and purification methods can be applied to the large-scale production of the rMeV N, which is essential for the development of new diagnostic tools and vaccines for acute and chronic MeV infections.

    Full Text Available Student mobility, provided through student exchange programs, is becoming one of the crucial elements of higher education institutions, especially in teacher training programs. The purpose of this study was to identify the reasons why Farabi exchange students chose to benefit from the program, the challenges faced by the students during the process and their suggestions regarding the exchange program and hence to evaluate the findings in terms of the purpose and functioning of the exchange program. In this qualitative research study, participants consisted of students who had taken advantage of the Farabi Exchange Program (n=5 and of students wishing to participate in the program (n=3 in various departments of a school of education. Data collected through a semi-structured interview form and a voice recorder were analyzed through descriptive and content analysis techniques. The findings demonstrated that the students benefited from the program due to two main factors: Domestic reasons (missing their families, financial facilities provided by the exchange program, and being in solidarity with the family members and reasons related to the Public Personnel Selection Examination (KPSS. It was also shown that the problems faced by students were due to the lack of an appropriate orientation program by Farabi offices, which strengthened the feeling of alienation among the students. The participants’ recommendations for the program were found to be pertinent to eliminating the problem about the lack of orientation.

    Today, computational fluid dynamics (CFD) is widely used in industry because of the availability of high performance computers. However, full-scale analysis poses problems owing to the limited resources and time. In this study, the performance and optimal size of a heat exchanger were calculated using the effectiveness-number of transfer units (ε-NTU) method and a database of characteristics heat exchanger. Information about the geometry and performance of various heat exchangers is collected, and the performance of the heat exchanger is calculated under the given operating conditions. To determine the optimal size of the heat exchanger, a Genetic Algorithm (GA) is used, and MATLAB and REFPROP are used for the calculation.

    2014-07-01

    In 2007 there was a sudden increase in HIV cases among intravenous drug users (IDUs) in Iceland. In 2007 - 2011 there were 34 new HIV cases among IDUs compared to four in the previous four year period. The purpose of this study was to assess whether needle exchange programs (NEPs) were cost-effective in preventing the spread of HIV among IDUs in Iceland. Cost-utility analysis was conducted from a societal perspective. Costs are presented at the 2011 price level and values were discounted using a 3% discount rate. A ten year period, 2011 - 2020 was compared with and without NEPs. The Incremental Cost-Utility Ratio (ICUR) was calculated as societal cost per quality adjusted life year (QALY). Sensitivity analysis was performed on study assumptions. The estimated societal costs associated with HIV infections among IDUs from 2011 - 2020 was 914.369.621 ISK without NEP and 947.653.758 ISK with NEP. Excess societal cost due to NEP was 33.284.137 ISK. Societal utility from NEP was 7,39 QALYs. Additionally, NEP prevented 4-5 HIV infections. The ICUR of providing NEP was 4.506.720 ISK. According to WHO an intervention is considered cost-effective if the ICUR is less than three-fold national GDP per capita. In 2011 the GDP per capita in Iceland was 15.315.000 ISK. Sensitivity analysis on study assumptions yielded a societal cost within the WHO limit. Therefore, the results indicate that NEPs are cost-effective in preventing the spread of HIV among IDUs in Iceland.

    Background Estonia has experienced an HIV epidemic among intravenous drug users (IDUs) with the highest per capita HIV prevalence in Eastern Europe. We assessed the effects of expanded syringe exchange programs (SEP) in the capital city, Tallinn, which has an estimated 10,000 IDUs. Methods SEP implementation was monitored with data from the Estonian National Institute for Health Development. Respondent driven sampling (RDS) interview surveys with HIV testing were conducted in Tallinn in 2005, 2007 and 2009 (involving 350, 350 and 327 IDUs respectively). HIV incidence among new injectors (those injecting for 80%), and young adults (mean ages 24 to 27 years). The proportion of new injectors decreased significantly over the years (from 21% in 2005 to 12% in 2009, p = 0.005). HIV prevalence among all respondents stabilized at slightly over 50% (54% in 2005, 55% in 2007, 51% in 2009), and decreased among new injectors (34% in 2005, 16% in 2009, p = 0.046). Estimated HIV incidence among new injectors decreased significantly from 18/100 person-years in 2005 and 21/100 person-years in 2007 to 9/100 person-years in 2009 (p = 0.026). Conclusions In Estonia, a transitional country, a decrease in the HIV prevalence among new injectors and in the numbers of people initiating injection drug use coincided with implementation of large-scale SEPs. Further reductions in HIV transmission among IDUs are still required. Provision of 70 or more syringes per IDU per year may be needed before significant reductions in HIV incidence occur.

    Full Text Available Concerns have been raised regarding environmental manganese exposure since high exposures have been associated with neurological disorders. The USA Environmental Protection Agency most recent human health risk assessment of inhaled manganese conducted in 1993 identified specific areas of uncertainty regarding manganese pharmacokinetics. This led to the development of a test rule under the USA Clean Air Act that required the generation of pharmacokinetic information on the inorganic manganese combustion products of the organometallic fuel additive methylcyclopentadienyl manganese tricarbonyl (MMT. The Alternative Tier 2 testing program for MMT, described in this paper, has yielded substantial pharmacokinetic data and has enabled the generation of physiologically based pharmacokinetic (PBPK models for manganese. These models are capable of predicting tissue manganese concentrations across a variety of dose routes, levels, and durations while accounting for factors such as age, gender, and reproductive status, enabling the consideration of tissue dosimetry in future risk assessments.

    MSWT-01, Mobile Surface Water Treatment, producing 1m3 per hour, is an alternative for providing clean water in flood disaster areas, and was developed at Bandung State Polytechnic for Manufacturing (Polman) as a part of institution research project. The combination of cartridge or membrane technology such as carbon block, MF, UF and filtration media is used for this machine, instead of coagulation-flocculation with chemical addition, due to emergency purposes related with its treatment processing time. The idea is that MSWT could be combined with Production Based Education (PBE) concept in Polman as a vocational education institution and students 'CSR', students social activities. With the number of implementation trials in real flood area condition, MSWT will be developed further based on the technical output result. The manufacturing process for improving or adding necessary features could be implemented as a student's project in PBE system. This might be an ideal combination alternative for such vocational institution that students get the product media for their PBE program and implement their work as a defined social activity. They will learn and experience related technical matters and more social interactions with the people and other disaster stakeholder as well.

  9. Altruistic donor triggered domino-paired kidney donation for unsuccessful couples from the kidney-exchange program.

    2010-04-01

    Between January 2000 and July 2009, 132 individuals inquired about altruistic kidney donation to strangers. These donors were willing to donate to genetically and emotionally unrelated patients. Some altruistic donors wished to donate to a specific person, but most wished to donate anonymously. In domino-paired donation, the altruistic donor donates to the recipient of an incompatible couple; the donor of that couple (domino-donor) donates to another couple or to the waiting list. In contrast to kidney-exchange donation where bilateral matching of couples is required, recipient and donor matching are unlinked in domino-paired donation. This facilitates matching for unsuccessful couples from the kidney-exchange program where blood type O prevails in recipients and is under-represented in donors. Fifty-one altruistic donors (39%) donated their kidney and 35 domino-donors were involved. There were 29 domino procedures, 24 with 1 altruistic donor and 1 domino-donor, 5 with more domino-donors. Eighty-six transplantations were performed. Donor and recipient blood type distribution in the couples limited allocation to blood type non-O waiting list patients. The success rate of domino-paired donation is dependent on the composition of the pool of incompatible pairs, but it offers opportunities for difficult to match pairs that were unsuccessful in the kidney-exchange program.

  11. The Anne Frank Haven: A case of an alternative educational program in an integrative Kibbutz setting

    1992-01-01

    The essential features of the programme of the Anne Frank Haven are the complete integration of children from low SES and different cultural backgrounds with Kibbutz children; a holistic approach to education; and the involvement of the whole community in an "open" residential school. After 33 years, it is argued that the experiment has proved successful in absorbing city-born youth in the Kibbutz, enabling at-risk populations to reach significant academic achievements, and ensuring their continued participation in the dominant culture. The basic integration model consists of "layers" of concentric circles, in dynamic interaction. The innermost circle is the class, the learning community. The Kibbutz community and the foster parents form a supportive, enveloping circle, which enables students to become part of the outer community and to intervene in it. A kind of meta-environment, the inter-Kibbutz partnership and the Israeli educational system, influence the program through decision making and guidance. Some of the principles of the Haven — integration, community involvement, a year's induction for all new students, and open residential settings — could be useful for cultures and societies outside the Kibbutz. The real "secret" of success of an alternative educational program is the dedicated, motivated and highly trained staff.

  12. The hybrid experimental simplex algorithm--an alternative method for 'sweet spot' identification in early bioprocess development: case studies in ion exchange chromatography.

    The capacity to locate efficiently a subset of experimental conditions necessary for the identification of an operating envelope is a key objective in many studies. We have shown previously how this can be performed by using the simplex algorithm and this paper now extends the approach by augmenting the established simplex method to form a novel hybrid experimental simplex algorithm (HESA) for identifying 'sweet spots' during scouting development studies. The paper describes the new algorithm and illustrates its use in two bioprocessing case studies conducted in a 96-well filter plate format. The first investigates the effect of pH and salt concentration on the binding of green fluorescent protein, isolated from Escherichia coli homogenate, to a weak anion exchange resin and the second examines the impact of salt concentration, pH and initial feed concentration upon the binding capacities of a FAb', isolated from E. coli lysate, to a strong cation exchange resin. Compared with the established algorithm, HESA was better at delivering valuable information regarding the size, shape and location of operating 'sweet spots' that could then be further investigated and optimized with follow up studies. To test how favorably these features of HESA compared with conventional DoE (design of experiments) methods, HESA results were also compared with approaches including response surface modeling experimental designs. The results show that HESA can return 'sweet spots' that are equivalently or better defined than those obtained from DoE approaches. At the same time the deployment of HESA to identify bioprocess-relevant operating boundaries was accompanied by comparable experimental costs to those of DoE methods. HESA is therefore a viable and valuable alternative route for identifying 'sweet spots' during scouting studies in bioprocess development. Copyright © 2012 Elsevier B.V. All rights reserved.

  17. Improvement in Vision Parameters for Participants Treated With Alternative Therapies in a 3-day Program.

    2015-01-01

    Eye conditions that are considered progressive and degenerative and for which the causation is generally poorly understood or not understood within conventional medicine can respond to natural therapeutic interventions that result in arrest and/or improvement of morbidity, with enhanced functional results. Because many of the treated conditions are age related, a delay of disease progression for 5 or even 10 y can mean an additional decade of independence for seniors. The 11 included ocular conditions are ordinarily considered incurable by any method except surgery and, even with surgery, the outcomes can be variable and/or transient. The research intended to demonstrate the effectiveness of alternative modalities-intravenous (IV) nutrition, oxidative therapy, microcurrent stimulation, and syntonic light therapy-in improving vision in chronic eye conditions, even when administered for a short period. The study was a retrospective, open-label, single-group design. All participants in the 3-d conference during the period covered were selected. The setting was ophthalmologist Edward Kondrot's Healing the Eye and Wellness Center near Tampa, FL, USA. The participants in this study were all patients attending 1 of 11 CAM treatment events at the author's center within 2 y. Each session lasted 3 d and the number of participants in each session ranged from 5-15 (mean = 13). The cohort numbered 152 patients who were diagnosed with ≥1 of 11 types of eye disease. Seventy-eight percent of the patients had either age-related macular degeneration (ARMD) or glaucoma, which, taken together, are the leading cause of blindness in persons >65 y. Each of 4 alternative modalities was provided at least once to each participant: (1) IV nutrition, (2) oxidative therapy, (3) microcurrent stimulation, and (4) syntonic light therapy. On the first day, a detailed treatment plan for each participant was developed. Each day consisted of 2 therapeutic eye programs, a stress reduction program

    1997-03-01

    The Alternative Fuels for Vehicles Fleet Demonstration Program (AFV-FDP) was a multiyear effort to collect technical data for use in determining the costs and benefits of alternative-fuel vehicles in typical applications in New York State. During 3 years of collecting data, 7.3 million miles of driving were accumulated, 1,003 chassis-dynamometer emissions tests were performed, 862,000 gallons of conventional fuel were saved, and unique information was developed about garage safety recommendations, vehicle performance, and other topics. Findings are organized by vehicle and fuel type. For light-duty compressed natural gas (CNG) vehicles, technology has evolved rapidly and closed-loop, electronically-controlled fuel systems provide performance and emissions advantages over open-loop, mechanical systems. The best CNG technology produces consistently low tailpipe emissions versus gasoline, and can eliminate evaporative emissions. Reduced driving range remains the largest physical drawback. Fuel cost is low ($/Btu) but capital costs are high, indicating that economics are best with vehicles that are used intensively. Propane produces impacts similar to CNG and is less expensive to implement, but fuel cost is higher than gasoline and safety codes limit use in urban areas. Light-duty methanol/ethanol vehicles provide performance and emissions benefits over gasoline with little impact on capital costs, but fuel costs are high. Heavy-duty CNG engines are evolving rapidly and provide large reductions in emissions versus diesel. Capital costs are high for CNG buses and fuel efficiency is reduced, but the fuel is less expensive and overall operating costs are about equal to those of diesel buses. Methanol buses provide performance and emissions benefits versus diesel, but fuel costs are high. Other emerging technologies were also evaluated, including electric vehicles, hybrid-electric vehicles, and fuel cells.

  1. Bidirectional Exchanges of Medical Students Between Institutional Partners in Global Health Clinical Education Programs: Putting Ethical Principles into Practice.

    Science.gov (United States)

    Rohrbaugh, Robert; Kellett, Anne; Peluso, Michael J

    One-third of US medical students participate in global health (GH) education, and approximately one-quarter of US medical schools have structured programs that offer special recognition in GH. GH clinical electives (GHCEs) are opportunities for students to experience a medical system and culture different from their own. GHCEs are administered through institutional affiliation agreements, often between an institution in a high-income country (HIC) and one in a low- or middle-income country (LMIC). Although these agreements suggest the exchange of students in both directions, GHCEs are traditionally characterized by students from HICs traveling to LMICs. The goal of this study was to investigate the availability of opportunities for students from LMICs participating in GHCEs at partner institutions in HICs and to describe the costs of these opportunities for students from LMICs. We conducted a web-based search of 30 US institutions previously identified as having structured programs in GH. We determined which of these schools have programs that accept medical students from international schools for GHCEs, as well as the administrative requirements, types of fees, and other costs to the international student based on information available on the web. Descriptive statistics were employed for the quantitative analysis of costs. We found that, although the majority of US institutions with structured GH programs sending students to sites abroad accept international students at their sites in the United States, nearly one-fifth of programs do not offer such opportunities for bidirectional exchange. We also characterized the substantial costs of such experiences, because this can represent a significant barrier for students from LMICs. Access to GHCEs in US partner institutions should be an important underlying ethical principle in the establishment of institutional partnerships. The opportunities available to and experiences of students from LMIC partner institutions are

  2. Equipoise: ethical, scientific, and clinical trial design considerations for compatible pair participation in kidney exchange programs.

    2015-06-01

    Compatible living donor/recipient pair participation (CPP) in kidney exchange (KE) transplantation may substantially increase transplant volumes and significantly mitigate the O blood group donor shortage in KE. Initial ethical analysis did not support CPP for two primary reasons: (1) KE would be "unbalanced," and (2) the possibility of undue influence experienced by the compatible pair living donor. Recent developments with CPP (modeling studies and small clinical experiences), have demonstrated substantial potential for increasing KE volumes. This encouraged us to reconsider initial ethical concerns, with a focus on the potential for a design of a prospective CPP clinical trial. This ethical reconsideration led us to conclude that the concept of unbalanced kidney exchanges (manifested primarily by differential benefit between compatible and incompatible pairs) is no longer as clear cut as originally conceived. In addition, application of two concepts substantially diminishes ethical concerns including: (1) "quasi-compatible" pairs, and (2) a priori definition of mitigating factors. We conclude that genuine uncertainty exists regarding whether kidney exchange is best performed with or without compatible pair participation and that a clinical trial is therefore warranted. © Copyright 2015 The American Society of Transplantation and the American Society of Transplant Surgeons.

    Community College students account for over 40% of all undergraduates in the US as well as the majority of minority students attending undergraduate courses. With issues in the geosciences such as; being the least diverse of all major STEM fields, an increasing number of retiring geoscientists, and a projected geoscience job growth not matching the number of geoscience graduates, the geoscience community needs to look at community colleges as a solution to these issues. A key factor for students entering and excelling in the geoscience is the opportunity for formative undergraduate field experiences. Formative field experiences go beyond one-day field excursions by incorporating field projects, interactive learning, and community building between participants in regions students are unfamiliar with. Unfortunately, these types of formative experiences often require logistics and resources that are not available or known to community college faculty. In order to build a framework for implementing formative field experiences by community colleges a two-week "field exchange" between two community colleges with different geological, social, and cultural settings was conducted. Supported with a supplemental grant from NSF, the "Border to Beltway" program provided 11 students from El Paso Community College and another 13 from Northern Virginia Community College with two one-week regional geology field trips: First, to West Texas in March 2014, and second, to the mid-Atlantic region in May 2014. Students were selected based on academic standing, non-traditional (minority, female, over 35, veteran) status, and interest in geology. Qualitative data collected from participants regarding the implementation of the field exchange include; student perception of geology before and after exchange, challenges students faced in the field or traveling for the first time, quantity and quality of projects given, and working with others from different backgrounds.

    Progression through the mitotic cell cycle requires periodic regulation of gene function at the levels of transcription, translation, protein-protein interactions, post-translational modification and degradation. However, the role of alternative splicing (AS) in the temporal control of cell cycle is not well understood. By sequencing the human transcriptome through two continuous cell cycles, we identify ~1300 genes with cell cycle-dependent AS changes. These genes are significantly enriched in functions linked to cell cycle control, yet they do not significantly overlap genes subject to periodic changes in steady-state transcript levels. Many of the periodically spliced genes are controlled by the SR protein kinase CLK1, whose level undergoes cell cycle-dependent fluctuations via an auto-inhibitory circuit. Disruption of CLK1 causes pleiotropic cell cycle defects and loss of proliferation, whereas CLK1 over-expression is associated with various cancers. These results thus reveal a large program of CLK1-regulated periodic AS intimately associated with cell cycle control. DOI: http://dx.doi.org/10.7554/eLife.10288.001 PMID:27015110

    To minimize the mortality rates of individuals affected by disasters, providing high-quality food relief during the initial stages of an emergency is crucial. The goal of this study was to develop a formulation for a high-energy, nutrient-dense prototype using linear programming (LP) model as a novel method for developing formulations for food products. The model consisted of the objective function and the decision variables, which were the formulation costs and weights of the selected commodities, respectively. The LP constraints were the Institute of Medicine and the World Health Organization specifications of the content of nutrients in the product. Other constraints related to the product's sensory properties were also introduced to the model. Nonlinear constraints for energy ratios of nutrients were linearized to allow their use in the LP. Three focus group studies were conducted to evaluate the palatability and other aspects of the optimized formulation. New constraints were introduced to the LP model based on the focus group evaluations to improve the formulation. LP is an appropriate tool for designing formulations of food products to meet a set of nutritional requirements. This method is an excellent alternative to the traditional 'trial and error' method in designing formulations. © 2017 Society of Chemical Industry. © 2017 Society of Chemical Industry.

    2014-12-01

    The history of alternative medicine is perhaps as long as the history of human medicine. The development of evidence-based medicine has not annihilated alternative medicine. On the contrary, more people turn to alternative medicine because this approach to treatment serves as an effective remedial or supportive treatment when used in conjunction with evidence-based medicine. In contemporary healthcare, alternative medicine is now an essential part of integrated medicine. In Taiwan, most professional medical practitioners have not received proper education about alternative medicine and therefore generally lack comprehensive knowledge on this subject. While alternative medicine may be effective when used with some patients, it may also impart a placebo effect, which helps restore the body and soul of the patients. Medical staff with advanced knowledge of alternative medicine may not only help patients but also improve the doctor-patient relationship. There is great diversity in alternative medicine, with some alternative therapies supported by evidence and covered by insurance. However, there also remain fraudulent medical practices that may be harmful to health. Medical staff must be properly educated so that they can provide patients and their family a proper understanding and attitude toward alternative medicine. Therefore, alternative medicine should be included in the standard medical education curriculum. Offering classes on alternative medicine in university for more than 10 years, the author shares his experiences regarding potential content, lecture subjects, group experience exercises, and in-class activities. This article is intended to provide a reference to professors in university medical education and offer a possible model for alternative medicine education in Taiwan.

    1999-09-01

    The ACE program furthered the national security interests of the US by promoting technical approaches to the implementation and verification of arms control treaties that the international community embraces. The Cox Committee report suggests that uncontrolled interactions were taking place between US and Chinese nuclear weapons scientists in the course of the ACE program. On the contrary, elaborate controls were in place at the very beginning and remained in place to control the interactions and protect US national security information. The ACE program payoff to national security was just beginning and its suspension, resulting from the Cox reports allegations, is a setback to US-China progress on arms control.

    Hospital-based violence intervention programs (HVIP) aim to reduce violent-injury recidivism by providing intensive case management services to high-risk patients who were violently injured. Although HVIP have been found effective at reducing recidivism, few studies have sought to identity how long their effects last. Additionally, prior studies have been limited by the fact that HVIP typically rely on self-report or data within their own healthcare system to identify new injuries. Our aim was to quantify the long-term recidivism rate of participants in an HVIP program using more objective and comprehensive data from a regional health information exchange. The study included 328 patients enrolled in Prescription for Hope (RxH), an HVIP, between January 2009 and August 2016. We obtained RxH participants' emergency department (ED) encounter data from a regional health information exchange database from the date of hospital discharge to February 2017. Our primary outcome was violent-injury recidivism rate of the RxH program. We also examined reasons for ED visits that were unrelated to violent injury. We calculated a 4.4% recidivism rate based on 8 years of statewide data, containing 1,575 unique encounters. More than 96% of participants were matched in the state database. Of the 15 patients who recidivated, only five were admitted for their injury. More than half of new violence-related injuries were treated outside of the HVIP-affiliated trauma center. The most common reasons for ED visits were pain (718 encounters), followed by suspected complications or needing additional postoperative care (181 encounters). Substance abuse, unintentional injuries, and suicidal ideation were also frequent reasons for ED visits. The low, long-term recidivism rate for RxH indicates that HVIPs have enduring positive effects on the majority of participants. Our results suggest that HVIP may further benefit patients by partnering with organizations that work to prevent suicide

    The Department of Energy is analyzing long-term storage and disposition alternatives for surplus weapons-usable fissile materials. A number of different disposition alternatives are being considered. These include facilities for storage, conversion and stabilization of fissile materials, immobilization in glass or ceramic material, fabrication of fissile material into mixed oxide (MOX) fuel for reactors, use of reactor based technologies to convert material into spent fuel, and disposal of fissile material using geologic alternatives. This paper will focus on how the objectives of reducing security and proliferation risks are being considered, and the possible facility impacts. Some of the areas discussed in this paper include: (1) domestic and international safeguards requirements, (2) non-proliferation criteria and measures, (3) the threats, and (4) potential proliferation, safeguards, and security issues and impacts on the facilities. Issues applicable to all of the possible disposition alternatives will be discussed in this paper. However, particular attention is given to the plutonium immobilization alternatives.

    Different higher education backgrounds in China and Germany led to challenges in the curriculum design at the beginning of our cooperative bachelor program in Optoelectronics Engineering. We see challenges in different subject requirements from both sides and in the German language requirements for Chinese students. The curriculum was optimized according to the ASIIN criteria, which makes it acceptable and understandable by both countries. German students are integrated into the Chinese class and get the same lectures like their Chinese colleagues. Intercultural and curriculum challenges are successfully solved. The results are summarized to provide an example for other similar international programs.

    Studies of batterer intervention and prevention programs (BIPPs) offer mixed results regarding their effect on recidivism. The purpose of this study was to examine the effectiveness of BIPP for cases assigned to a misdemeanor family court. This study focused on determining whether BIPP cases, compared with alternative sanctions, had significantly lower recidivism rates 12 months after program involvement. Findings indicated that BIPP was more effective than jail or regular dismissal in reducing the likelihood of future arrests, but not plea deferred adjudication and conditional dismissal. Results argue toward the efficacy of some form of treatment versus simply receiving jail time. © The Author(s) 2015.

  11. An EMT-driven alternative splicing program occurs in human breast cancer and modulates cellular phenotype.

    2011-08-01

    Full Text Available Epithelial-mesenchymal transition (EMT, a mechanism important for embryonic development, plays a critical role during malignant transformation. While much is known about transcriptional regulation of EMT, alternative splicing of several genes has also been correlated with EMT progression, but the extent of splicing changes and their contributions to the morphological conversion accompanying EMT have not been investigated comprehensively. Using an established cell culture model and RNA-Seq analyses, we determined an alternative splicing signature for EMT. Genes encoding key drivers of EMT-dependent changes in cell phenotype, such as actin cytoskeleton remodeling, regulation of cell-cell junction formation, and regulation of cell migration, were enriched among EMT-associated alternatively splicing events. Our analysis suggested that most EMT-associated alternative splicing events are regulated by one or more members of the RBFOX, MBNL, CELF, hnRNP, or ESRP classes of splicing factors. The EMT alternative splicing signature was confirmed in human breast cancer cell lines, which could be classified into basal and luminal subtypes based exclusively on their EMT-associated splicing pattern. Expression of EMT-associated alternative mRNA transcripts was also observed in primary breast cancer samples, indicating that EMT-dependent splicing changes occur commonly in human tumors. The functional significance of EMT-associated alternative splicing was tested by expression of the epithelial-specific splicing factor ESRP1 or by depletion of RBFOX2 in mesenchymal cells, both of which elicited significant changes in cell morphology and motility towards an epithelial phenotype, suggesting that splicing regulation alone can drive critical aspects of EMT-associated phenotypic changes. The molecular description obtained here may aid in the development of new diagnostic and prognostic markers for analysis of breast cancer progression.

  13. Nuclear proliferation and civilian nuclear power: report of the Nonproliferation Alternative Systems Assessment Program. Volume VIII. Advanced concepts

    Energy Technology Data Exchange (ETDEWEB)

    1979-12-01

    The six advanced concepts for nuclear power systems that were selected for evaluation are: the fast mixed-spectrum reactor; the denatured molten-salt reactor; the mixed-flow gaseous-core reactor; the linear-accelerator fuel-regenerator reactor; the ternary metal-fueled electronuclear fuel-producer reactor; and the tokamak fusion-fission hybrid reactor. The design assessment was performed by identifying needs in six specific areas: conceptual plant design; reactor-physics considerations; fuel cycle alternatives; mechanical and thermal-hydraulic considerations; selection, development, and availability of materials; and engineering and operability. While none of the six concepts appears to be a credible commercial alternative to the liquid-metal fast-breeder within the Nonproliferation Alternative Systems Assessment Program horizon of 2025, there are a number of reasons for continued interest in the fast mixed-spectrum reactor: it is a once-through cycle fast reactor with proliferation risk characteristics similar to those of the light-water reactor; only about one-third as much uranium is required as for the once-through light-water reactor; the system will benefit directly from fast-breeder development programs; and, finally, the research and development required to develop the high-burnup metal fuel could benefit the on-going liquid-metal fast-breeder reactor program. Accordingly, a limited research and development effort on the high-burnup fuel seems justified, at present.

  15. Sequential computation of elementary modes and minimal cut sets in genome-scale metabolic networks using alternate integer linear programming

    Energy Technology Data Exchange (ETDEWEB)

    Song, Hyun-Seob; Goldberg, Noam; Mahajan, Ashutosh; Ramkrishna, Doraiswami

    2017-03-27

    Elementary (flux) modes (EMs) have served as a valuable tool for investigating structural and functional properties of metabolic networks. Identification of the full set of EMs in genome-scale networks remains challenging due to combinatorial explosion of EMs in complex networks. It is often, however, that only a small subset of relevant EMs needs to be known, for which optimization-based sequential computation is a useful alternative. Most of the currently available methods along this line are based on the iterative use of mixed integer linear programming (MILP), the effectiveness of which significantly deteriorates as the number of iterations builds up. To alleviate the computational burden associated with the MILP implementation, we here present a novel optimization algorithm termed alternate integer linear programming (AILP). Results: Our algorithm was designed to iteratively solve a pair of integer programming (IP) and linear programming (LP) to compute EMs in a sequential manner. In each step, the IP identifies a minimal subset of reactions, the deletion of which disables all previously identified EMs. Thus, a subsequent LP solution subject to this reaction deletion constraint becomes a distinct EM. In cases where no feasible LP solution is available, IP-derived reaction deletion sets represent minimal cut sets (MCSs). Despite the additional computation of MCSs, AILP achieved significant time reduction in computing EMs by orders of magnitude. The proposed AILP algorithm not only offers a computational advantage in the EM analysis of genome-scale networks, but also improves the understanding of the linkage between EMs and MCSs.

    Statistical and genetic programming techniques have been used to predict the software development effort of large software projects. In this paper, a genetic programming model was used for predicting the effort required in individually developed projects. Accuracy obtained from a genetic programming model was compared against one generated from the application of a statistical regression model. A sample of 219 projects developed by 71 practitioners was used for generating the two models, whereas another sample of 130 projects developed by 38 practitioners was used for validating them. The models used two kinds of lines of code as well as programming language experience as independent variables. Accuracy results from the model obtained with genetic programming suggest that it could be used to predict the software development effort of individual projects when these projects have been developed in a disciplined manner within a development-controlled environment.

    Described herein is encouraging chemical biology. Chemistry to elucidate fundamental elementary reactions involved in various phenomena and actual conditions of key molecules must be supported by physics for understanding behavior of electrons. The research themes attracting attention recently include sex pheromones of insects, photosynthesis, reactions involving antigens or antibodies, recognition of molecules, memorizing and leaning, and so on. Fundamentals of the life-related phenomena are being elucidated from structures of the related substances and reaction mechanisms involved by the NMR and X-ray diffraction analyses to determine structures of these substances and also by theoretical quantum chemistry to understand electron transfer phenomena within life-related molecules. Also described are international academic exchange programs promoted by the Ministry of Education. Academic researches for the pursuit of truth are crossing the borders in nature. International exchange to promote information exchange and joint researches by researchers of different nationalities pursuing common themes is indispensable for scientific development. The Ministry of Education has been promoting the international academic exchange programs by providing subsidies for international academic researches, promoting international exchange projects at various institutions, such as national universities, inter-university organizations and Japan Society for the Promotion of Science, and supporting scientific projects promoted by UNESCO. 1 fig., 1 tab.

  9. Evolutionary effects of alternative artificial propagation programs: implications for viability of endangered anadromous salmonids.

    Most hatchery programs for anadromous salmonids have been initiated to increase the numbers of fish for harvest, to mitigate for habitat losses, or to increase abundance in populations at low abundance. However, the manner in which these programs are implemented can have significant impacts on the evolutionary trajectory and long-term viability of populations. In this paper, we review the potential benefits and risks of hatchery programs relative to the conservation of species listed under the US Endangered Species Act. To illustrate, we present the range of potential effects within a population as well as among populations of Chinook salmon (Oncorhynchus tshawytscha) where changes to major hatchery programs are being considered. We apply evolutionary considerations emerging from these examples to suggest broader principles for hatchery uses that are consistent with conservation goals. We conclude that because of the evolutionary risks posed by artificial propagation programs, they should not be viewed as a substitute for addressing other limiting factors that prevent achieving viability. At the population level, artificial propagation programs that are implemented as a short-term approach to avoid imminent extinction are more likely to achieve long-term population viability than approaches that rely on long-term supplementation. In addition, artificial propagation programs can have out-of-population impacts that should be considered in conservation planning.

    2013-06-01

    In 2011, anecdotal data indicated that 3,4-methylene-dioxy-pyrovalerone (MDPV) might become popular among needle exchange program (NEP) clients in Hungary as a possible substitute for formerly used substances such as amphetamines and heroin. The aim of the study reported here was to examine how the emergence of MDPV influenced the choice of the injecting substance among NEP clients. A total of 183 injecting drug users (IDUs) participating in the largest NEP in Budapest agreed to participate in the study and report on their drug use habits. During 2011, remarkable changes occurred in the structure of the primary injected substances. Amphetamine was cited as the primary injected substance by 45.9% of the respondents and MDPV by 48.1%. Close to half of the former amphetamine injectors had switched to MDPV (64 persons, 45.1%) as had 10 (41.7%) of the former heroin injectors and 11 (78.6%) of those using other substances (cocaine and mephedrone). The appearance of MDPV on the illegal drug market had a substantial effect on the drug use patterns of the IDU population. Further research should be conducted to explain the changes, that might include the purity, price and availability of amphetamine and heroin.

    2009-01-01

    Most chiropractic colleges do not offer independent neuroscience courses because of an already crowded curriculum. The Palmer College of Chiropractic Florida has developed and implemented an integrated neuroscience program that incorporates neurosciences into different courses. The goals of the program have been to bring neurosciences to students, excite students about the interrelationship of neuroscience and chiropractic, improve students' understanding of neuroscience, and help the students understand the mechanisms underpinning the chiropractic practice. This study provides a descriptive analysis on how the integrated neuroscience program is taught via students' attitudes toward neuroscience and the comparison of students' perceptions of neuroscience content knowledge at different points in the program. A questionnaire consisting of 58 questions regarding the neuroscience courses was conducted among 339 students. The questionnaire was developed by faculty members who were involved in teaching neuroscience and administered in the classroom by faculty members who were not involved in the study. Student perceptions of their neuroscience knowledge, self-confidence, learning strategies, and knowledge application increased considerably through the quarters, especially among the 2nd-year students. The integrated neuroscience program achieved several of its goals, including an increase in students' confidence, positive attitude, ability to learn, and perception of neuroscience content knowledge. The authors believe that such gains can expand student ability to interpret clinical cases and inspire students to become excited about chiropractic research. The survey provides valuable information for teaching faculty to make the course content more relevant to chiropractic students.

  15. Alternative Ultrasound Gel for a Sustainable Ultrasound Program: Application of Human Centered Design.

    Directory of Open Access Journals (Sweden)

    Margaret Salmon

    Full Text Available This paper describes design of a low cost, ultrasound gel from local products applying aspects of Human Centered Design methodology. A multidisciplinary team worked with clinicians who use ultrasound where commercial gel is cost prohibitive and scarce. The team followed the format outlined in the Ideo Took Kit. Research began by defining the challenge "how to create locally available alternative ultrasound gel for a low-resourced environment? The "End-Users," were identified as clinicians who use ultrasound in Democratic Republic of the Congo and Ethiopia. An expert group was identified and queried for possible alternatives to commercial gel. Responses included shampoo, oils, water and cornstarch. Cornstarch, while a reasonable solution, was either not available or too expensive. We then sought deeper knowledge of locally sources materials from local experts, market vendors, to develop a similar product. Suggested solutions gleaned from these interviews were collected and used to create ultrasound gel accounting for cost, image quality, manufacturing capability. Initial prototypes used cassava root flour from Great Lakes Region (DRC, Rwanda, Uganda, Tanzania and West Africa, and bula from Ethiopia. Prototypes were tested in the field and resulting images evaluated by our user group. A final prototype was then selected. Cassava and bula at a 32 part water, 8 part flour and 4 part salt, heated, mixed then cooled was the product design of choice.

  1. Sequential computation of elementary modes and minimal cut sets in genome-scale metabolic networks using alternate integer linear programming.

    2017-08-01

    Elementary (flux) modes (EMs) have served as a valuable tool for investigating structural and functional properties of metabolic networks. Identification of the full set of EMs in genome-scale networks remains challenging due to combinatorial explosion of EMs in complex networks. It is often, however, that only a small subset of relevant EMs needs to be known, for which optimization-based sequential computation is a useful alternative. Most of the currently available methods along this line are based on the iterative use of mixed integer linear programming (MILP), the effectiveness of which significantly deteriorates as the number of iterations builds up. To alleviate the computational burden associated with the MILP implementation, we here present a novel optimization algorithm termed alternate integer linear programming (AILP). Our algorithm was designed to iteratively solve a pair of integer programming (IP) and linear programming (LP) to compute EMs in a sequential manner. In each step, the IP identifies a minimal subset of reactions, the deletion of which disables all previously identified EMs. Thus, a subsequent LP solution subject to this reaction deletion constraint becomes a distinct EM. In cases where no feasible LP solution is available, IP-derived reaction deletion sets represent minimal cut sets (MCSs). Despite the additional computation of MCSs, AILP achieved significant time reduction in computing EMs by orders of magnitude. The proposed AILP algorithm not only offers a computational advantage in the EM analysis of genome-scale networks, but also improves the understanding of the linkage between EMs and MCSs. The software is implemented in Matlab, and is provided as supplementary information . hyunseob.song@pnnl.gov. Supplementary data are available at Bioinformatics online.

  2. AlterBBN: A program for calculating the BBN abundances of the elements in alternative cosmologies

    Arbey, Alexandre

    2012-01-01

    We describe AlterBBN, a public C program for evaluating the abundances of the elements generated by Big-Bang nucleosynthesis (BBN). This program enables the user to compute the abundances of the elements in the standard model of cosmology, and additionally provides possibilities to alter the assumptions of the cosmological model in order to study their consequences on the abundances of the elements. In particular the baryon-to-photon ratio and the effective number of neutrinos, as well as the expansion rate and the entropy content of the Universe during BBN can be modified in AlterBBN. Such features allow the user to test the cosmological models by confronting them to BBN constraints. A presentation of the physics of BBN and the features of AlterBBN is provided here under the form of a manual.

    Orthogonal high-resolution separations are critical for attaining improved analytical dynamic range and protein coverage in proteomic measurements. High pH reversed-phase liquid chromatography (RPLC) followed by fraction concatenation affords better peptide analysis than conventional strong-cation exchange (SCX) chromatography applied for the two-dimensional proteomic analysis. For example, concatenated high pH reversed-phase liquid chromatography increased identification for peptides (1.8-fo...

  5. From Punishment to Treatment: The “Clinical Alternative to Punitive Segregation” (CAPS Program in New York City Jails

    2016-02-01

    Full Text Available The proliferation of jails and prisons as places of institutionalization for persons with serious mental illness (SMI has resulted in many of these patients receiving jail-based punishments, including solitary confinement. Starting in 2013, the New York City (NYC jail system developed a new treatment unit for persons with SMI who were judged to have violated jail rules (and previously would have been punished with solitary confinement called the Clinical Alternative to Punitive Segregation (CAPS unit. CAPS is designed to offer a full range of therapeutic activities and interventions for these patients, including individual and group therapy, art therapy, medication counseling and community meetings. Each CAPS unit requires approximately $1.5 million more investment per year, largely in additional staff as compared to existing mental health units, and can house approximately 30 patients. Patients with less serious mental illness who received infractions were housed on units that combined solitary confinement with some clinical programming, called Restrictive Housing Units (RHU. Between 1 December 2013 and 31 March 2015, a total of 195 and 1433 patients passed through the CAPS and RHU units, respectively. A small cohort of patients experienced both CAPS and RHU (n = 90. For these patients, their rates of self-harm and injury were significantly lower while on the CAPS unit than when on the RHU units. Improvements in clinical outcomes are possible for incarcerated patients with mental illness with investment in new alternatives to solitary confinement. We have started to adapt the CAPS approach to existing mental health units as a means to promote better clinical outcomes and also help prevent jail-based infractions. The cost of these programs and the dramatic differences in length of stay for patients who earn these jail-based infractions highlight the need for alternatives to incarceration, some of which have recently been announced in NYC.

    To determine the impact of the implementation of a needle-exchange program (NEP) on the spread of human immunodeficiency virus (HIV) in an injection drug user (IDU) community. We conducted a Monte Carlo simulation study of a theoretical population of 10000 IDUs. The population was followed monthly from 1984 to 2000. HIV was assumed to be transmitted only by needle sharing. The NEP was introduced in 1989 and evaluated over a period of 11 years. The impacts of the proportion of the population attending the NEP, the risk level of IDUs attending the NEP, the reduction in needle-sharing frequency, and the number of new needle-sharing partners acquired at the NEP on prevalence and incidence of HIV were determined. Increasing the proportion of the population who always attend the NEP and eliminating needle-sharing incidents among IDUs who always attended the NEP were the most effective ways of reducing the spread of HIV. Attracting high-risk users instead of lower risk users to the NEP also reduced the spread of HIV, but to a lesser extent. NEPs are effective at reducing the spread of HIV; even under the worst case scenario of low risk users more likely to attend the NEP, one additional partner per month as a result of attending the NEP, and poor NEP attendance, the estimated prevalence was still less than that from the scenario without an NEP. Under our model, NEPs were shown to reduce the spread of HIV significantly. Efforts should be focused on getting as many IDUs as possible to become regular NEP attenders and stop sharing needles rather than partially reducing the frequency of sharing by a larger number of IDUs.

    Incarceration is common among people who inject drugs. Prior research has shown that incarceration is a marker of elevated risk for opioid overdose, suggesting that the criminal justice system may be an important, under-utilized venue for implementing overdose prevention strategies. To better understand the feasibility and acceptability of such strategies, we evaluated the utilization of naloxone-based overdose prevention training among people who inject drugs with and without a history of incarceration. We surveyed clients who utilize a multi-site syringe exchange program (SEP) in 2 cities in the Midwestern United States. Participants completed an 88-item, computerized survey assessing history of incarceration, consequences associated with injection, injecting practices, and uptake of harm reduction strategies. Among 543 respondents who injected drugs in the prior 30 days, 243 (43%) reported prior incarceration. Comparing those with and without a history of incarceration, there were no significant differences with respect to age, gender, or race. Those who observed an overdose, experienced overdose, and received training to administer or have administered naloxone were more likely to report incarceration. Overall, 69% of previously incarcerated clients had been trained to administer naloxone. People who inject drugs with a history of incarceration appear to have a higher risk of opioid overdose than those never incarcerated, and are more willing to utilize naloxone as an overdose prevention strategy. Naloxone training and distribution is an important component of comprehensive prevention services for persons with opioid use disorders. Expansion of services for persons leaving correctional facilities should be considered. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    2001-03-01

    In Marseille, southeastern France, HIV prevention programs for injection drug users (IDUs) simultaneously include access to sterile syringes through needle exchange programs (NEPs), legal pharmacy sales and, since 1996, vending machines that mechanically exchange new syringes for used ones. The purpose of this study was to compare the characteristics of IDUs according to the site where they last obtained new syringes. During 3 days in September 1997, all IDUs who obtained syringes from 32 pharmacies, four NEPs and three vending machines were offered the opportunity to complete a self-administered questionnaire on demographics, drug use characteristics and program utilization. Of 485 individuals approached, the number who completed the questionnaire was 141 in pharmacies, 114 in NEPs and 88 at vending machines (response rate = 70.7%). Compared to NEP users, vending machine users were younger and less likely to be enrolled in a methadone program or to report being HIV infected, but more likely to misuse buprenorphine. They also had lower financial resources and were less likely to be heroin injectors than both pharmacy and NEP users. Our results suggest that vending machines attract a very different group of IDUs than NEPs, and that both programs are useful adjuncts to legal pharmacy sales for covering the needs of IDUs for sterile syringes in a single city. Assessment of the effectiveness and cost-effectiveness of combining such programs for the prevention of HIV and other infectious diseases among IDUs requires further comparative research.

    2003-01-01

    Full Text Available The feasibility of using augmented block designs and spatial analysis methods for early stage selection in eucalyptus breeding programs was tested. A total of 113 half-sib progenies of Eucalyptus urophylla and eight clones were evaluated in an 11 x 11 triple lattice experiment at two locations: Posto da Mata (Bahia, Brazil and São Mateus (Minas Gerais, Brazil. Four checks were randomly allocated within each block. Plots consisted of 15 m long rows containing 6 plants spaced 3 m apart. The girth at breast height (cm/plant was evaluated at 19 and 26 months of age. Variance analyses were performed according to the following methods: lattice design, randomized complete block design, augmented block design, Papadakis method, moving means method, and check plots. Comparisons among different methods were based on the magnitude of experimental errors and precision of the estimates of genetic and phenotypic parameters. General results indicated that augmented block design is useful to evaluate progenies and clones in early selection in eucalyptus breeding programs using moderate and low selection intensities. However, this design is not suitable for estimating genetic and phenotypic parameters due to its low precision. Check plots, nearest neighbour, Papadakis (1937, and moving means methods were efficient in removing the heterogeneity within blocks. These efficiencies were compared to that in lattice analysis for estimation of genetic and phenotypic parameters.

    2015-04-01

    Full Text Available Natural killer (NK cells comprise a heterogeneous population of cells important for pathogen defense and cancer surveillance. However, the functional significance of this diversity is not fully understood. Here, we demonstrate through transcriptional profiling and functional studies that the activating receptor DNAM-1 (CD226 identifies two distinct NK cell functional subsets: DNAM-1+ and DNAM-1− NK cells. DNAM-1+ NK cells produce high levels of inflammatory cytokines, have enhanced interleukin 15 signaling, and proliferate vigorously. By contrast, DNAM-1− NK cells that differentiate from DNAM-1+ NK cells have greater expression of NK-cell-receptor-related genes and are higher producers of MIP1 chemokines. Collectively, our data reveal the existence of a functional program of NK cell maturation marked by DNAM-1 expression.

    1992-03-01

    This report documents work undertaken by the Pacific Northwest Laboratory (PNL) and its contractors to assist the Bonneville Power Administration (Bonneville) in assessing the potential environmental consequences of new power resources. A major purpose of this effort is to describe and evaluate the techniques available for economic valuation of environmental costs. Another is to provide estimates of the environmental costs associated with specific power resources called for under Bonneville's Resource Programs.

Many of these elements were not present by design but accentuated value, an element rarely included in concept-oriented curriculum approaches including those that purport to incorporate affect as an outcome measure. The possibilities for an alternative and more organic model of curricular change are discussed.

  13. MLP: A Parallel Programming Alternative to MPI for New Shared Memory Parallel Systems

    Taft, James R.

    1999-01-01

    Recent developments at the NASA AMES Research Center's NAS Division have demonstrated that the new generation of NUMA based Symmetric Multi-Processing systems (SMPs), such as the Silicon Graphics Origin 2000, can successfully execute legacy vector oriented CFD production codes at sustained rates far exceeding processing rates possible on dedicated 16 CPU Cray C90 systems. This high level of performance is achieved via shared memory based Multi-Level Parallelism (MLP). This programming approach, developed at NAS and outlined below, is distinct from the message passing paradigm of MPI. It offers parallelism at both the fine and coarse grained level, with communication latencies that are approximately 50-100 times lower than typical MPI implementations on the same platform. Such latency reductions offer the promise of performance scaling to very large CPU counts. The method draws on, but is also distinct from, the newly defined OpenMP specification, which uses compiler directives to support a limited subset of multi-level parallel operations. The NAS MLP method is general, and applicable to a large class of NASA CFD codes.

  14. Nuclear proliferation and civilian nuclear power. Report of the Nonproliferation Alternative Systems Assessment Program. Volume VIII. Advanced concepts

    Energy Technology Data Exchange (ETDEWEB)

    1980-06-01

    The goal of the Nonproliferation Alternative Systems Assessment Program has been to provide recommendations for the development and deployment of more proliferation-resistant civilian nuclear-power systems without jeopardizing the development of nuclear energy. In principle, new concepts for nuclear-power systems could be designed so that materials and facilities would be inherently more proliferation-resistant. Such advanced, i.e., less-developed systems, are the subject of this volume. Accordingly, from a number of advanced concepts that were proposed for evaluation, six representative concepts were selected: the fast mixed-spectrum reactor; the denatured molten-salt reactor; the mixed-flow gaseous-core reactor; the linear-accelerator fuel-regenerator reactor; the ternary metal-fueled electronuclear fuel-producer reactor; and the tokamak fusion-fission hybrid reactor.

    In potato (Solanum tuberosum L.) suspension cells, the expression of the gene encoding alternative oxidase (AOX) and H2O2 accumulation were induced by treatment with beta-glucan elicitor. The inhibition of catalase activity enhanced both AOX mRNA expression and the production of H2O2, whereas the ascorbate peroxidase inhibitor did not have any effect on these responses. Simultaneous inhibition of catalase and AOX activities in elicited cells dramatically increased H2O2 accumulation, leading to the disruption of mitochondrial membrane potential (deltapsi(m)) and programmed cell death (PCD). The results demonstrate, for the first time, that not only AOX but also catalase plays a central role in the suppression of mitochondrial deltapsi(m) breakdown and PCD induced by beta-glucan elicitor.

    Village- and central nucleus-based schemes were simulated and evaluated for their relative bio-economic efficiencies, using Ethiopia's Menz sheep as example. The schemes were: village-based 2-tier (Scheme-1) and 1-tier (Scheme-2) cooperative village breeding schemes, dispersed village-based nuclei scheme (Scheme-3), conventional 2-tier central nucleus-based scheme (Scheme-4), and schemes linking a central nucleus and village multiplier nuclei with selection in central nucleus (Scheme-5) or in both central and village nuclei (Scheme-6). Among village-based schemes, Scheme-1 gave the highest genetic progress, while Scheme-2 was economically the most efficient with genetic gain in the breeding objective of Birr 5.6 and a profit of Birr 37.2/ewe/year. The central nucleus schemes were more efficient than the village schemes. Scheme-4 was the most efficient with genetic gain in the breeding objective of Birr 13.5 and a profit of Birr 71.2, but is operationally more difficult as it requires a very large central nucleus. The choice between village and central nucleus-based schemes would depend on local conditions (availability of infrastructure, logistics and technical knowhow and support). Linking central nucleus with village-based nuclei (Scheme-6) would be a feasible option to overcome the operational difficulties of the conventional central nucleus scheme. If a village-based breeding program is envisaged as should be the 1st step in most low-input systems, then Scheme-2 is the most efficient. To scale out to an entire Menz breed level, Scheme-3 would be recommended. © 2014 Blackwell Verlag GmbH.

  17. Critiques of World-Systems Analysis and Alternatives: Unequal Exchange and Three Forms of Class and Struggle in the Japan–US Silk Network, 1880–1890

    Full Text Available Sympathetic critics of world-system analysis contend that its systemic level of abstraction results in one-sided generalizations of systemic change. Unequal exchange theory and commodity chain analysis similarly reduce distinct and historical forms of labor and their interrelationships to common functional and ahistorical essences. This paper applies an incorporated comparisons method to give historical content to an understanding of unequal exchange and global inequality through a study of the Japan–US silk network’s formation and change during the mid 1880–1890s. Analysis of unequal exchange processes requires, in this case, an examination of the mutual integration and transformation of distinct labor and value forms —peasant sericulture, ?lature wage-labor, and industrial silk factory wage-labor—and the infundibular market forces they structured. These relations were decisively conditioned by new landlordism and debt-peonage, class-patriarchy, state mediations, migration, and by peasant and worker struggles against deteriorating conditions. Indeed, the transitional nature of the silk network’s formation, which concluded the Tokugawa system and decisively contributed to Japan’s emergence as a nation-state of the capitalist world-economy, was signi?ed by the very last millenarian and quasi-modern peasant uprising in 1884 among indebted sericulturists, the very ?rst recorded factory strikes in 1885–86, by women raw silk reelers in K?fu, and by strikes among unionizing workers in patriarchal and mechanized silk factories in Paterson, New Jersey, 1885–86 (Boles 1996, 1998. The “local” conditions of each con?ict were molded by the interdependence of those conditions that constituted a formative part of the world-system and its development. In the face of struggles and intensifying world-market competition, Japanese and US manufacturers took opposite spatial strategies of regional expansion to overcome the structural constraints of

    Although barter is often perceived as something that proceeded money, barter is still used. The focus of the paper is on barter exchanges. Barter exchanges are used both in developing countries as well as in developed countries (including the U.S.). They are used by both organizations...... and individuals. They usually allow to exchange good but some include also services. Some exchanges allow only for bi-directional barter, i.e. when only two parties are involved in the exchange. But probably most of the barter exchanges use barter money; this makes it easier to exchange goods and services...

    1980-01-22

    This report is the result of a study carried out to determine options and alternatives for the Education Programs Division (EPD) of the Department of Energy. In the conduct of this study, numerous individuals from various concerned institutions were interviewed. While the project scope clearly precluded contact with every involved or potentially involved party, a concerted effort was made to obtain a representative sampling of the opinions and views of relevant government, academic and private sector agencies and organizations. A listing of those contacted, excluding the Department of Energy, is provided. In addition to interviews, an extensive range of literature was drawn upon including memoranda, brochures, program statements, school-enrollment data, speeches and the like. It was determined during this study that a wide range of public and private institutions are actively involved in the energy-education field. Oil companies, utilities, public interest groups, schools, agencies at every level of government, and others are formulating and delivering education which is enormously varied. It was concluded, however, that the public is not being reached, partially because current efforts are unfocused and partially because the public has become inured to problems and resistant to many of the traditional means of education. The study found that within this crowded and varied energy education field the Department of Energy is well placed to begin to provide direction and focus to the widespread activity now occurring.

    The main aim of this research was to describe the availability and integration of supportive care programs (SCPs), particularly complementary and alternative medicine (CAM) services, for adults in Australian oncology treatment centers. We systematically searched 124 Australian hospitals listed as having an oncology department out of a total of 1157 hospitals listed in the Australian Hospitals and Aged Care Databases (2014), and assessed their website and relevant leaflets. Direct contact was made with a relevant staff member in each hospital. Data were collected regarding the range of SCP and CAM services available. Of the 124 hospitals, 89 (72%) provide nonspecific guidance to SCP or a staff member (e.g. social worker or care coordinator) who directs patients, advising them about SCP; 35 hospitals (28%) provide active referral to SCP, of which 24 of 35 (69%) include CAM in their service, with individual variation in how it is incorporated. Only 11 (46%) of these 24 CAM incorporated oncology centers in Australia provided systematically integrated CAM programs. The majority of Australian oncology departments do not have CAM incorporated into their services. In those that do, less than half had systemically integrated CAM. The types of CAM available, how they are accessed and how they are integrated varied across hospitals. Further research is required to understand how to successfully and systematically integrate cancer-specific supportive care such as CAM into Australian cancer services. © 2016 John Wiley & Sons Australia, Ltd.

    About half of all patients with cancer use complementary or alternative medicine (CAM). In 2013, we started a lecture program for patients, followed by evidence-based recommendations on counseling on CAM. These recommendations have been published before by this working group. The aim of the program is to provide scientific facts on the most often used CAM methods in standardized presentations which help patients discuss the topic with their oncologists and support shared decision making. The article presents the evaluation of the pilot phase. Participants received a standardized questionnaire before the start of the lecture. The questionnaire comprises four parts: demographic data, data concerning experience with CAM, satisfaction with the lecture, and needs for further information on CAM. In 2013, seven lectures on CAM were given in cooperation with regional branches of the German Cancer Society in several German states. Four hundred sixty patients and relatives took part (75% females and 16% males). Forty-eight percent formerly had used CAM. Most often named sources of information on CAM were print media (48%) and the Internet (37%). Most participants rated additional written information valuable. About one third would like to have an individual consultation concerning CAM. A standardized presentation of evidence on CAM methods most often used, together with recommendations on the self-management of symptoms, is highly appreciated. The concept of a highly interactive lecture comprising is feasible and if presented in lay terminology, adequate. In order to give additional support on the topic, written information should be provided as the first step.

    To implement and to assess the efficacy of a school-based, sport team-centered program to prevent young female high school athletes' disordered eating and body-shaping drug use. Prospective controlled trial in 18 high schools, with balanced random assignment by school to the intervention and usual-care control conditions. We enrolled 928 students from 40 participating sport teams. Mean age was 15.4 years, 92.2% were white, and follow-up retention was 72%. The ATHENA (Athletes Targeting Healthy Exercise and Nutrition Alternative) curriculum's 8 weekly 45-minute sessions were incorporated into a team's usual practice activities. Content was gender-specific, peer-led, and explicitly scripted. Topics included healthy sport nutrition, effective exercise training, drug use and other unhealthy behaviors' effects on sport performance, media images of females, and depression prevention. We assessed participants by confidential questionnaire prior to and following their sport season. We determined program effects using an analysis of covariance-based approach within the Generalized Estimating Equation framework. Experimental athletes reported significantly less ongoing and new use of diet pills and less new use of athletic-enhancing substances (amphetamines, anabolic steroids, and sport supplements) (Pdiet pills (P<.05), vomiting to lose weight (P<.05), and use of tobacco (P<.05) and muscle-building supplements (P<.005). The program's curriculum components were altered appropriately (controlling mood [P<.005], refusal skills [P = .05], belief in the media [P<.005], and perceptions of closest friends' body-shaping drug use [P<.001]). Sport teams are effective natural vehicles for gender-specific, peer-led curricula to promote healthy lifestyles and to deter disordered eating, athletic-enhancing substance use, and other health-harming behaviors.

  3. Model study of the Mediterranean-Atlantic water exchange prior to the Messinian Salinity Crisis: An alternative to the "siphon theory"

    During the Late Miocene the Mediterranean Sea and the Atlantic Ocean were connected by means of two marine passages - the Betic and Rifian corridors. The severe restriction of these corridors due to tectonic processes, in combination with glacio-eustatic sea-level fluctuations, resulted in the so-called Messinian Salinity Crisis. During this event thick sequences of evaporites were deposited in the Mediterranean Sea evidencing dramatic changes in the palaeoenvironmental conditions. Although the present-day water exchange through the Strait of Gibraltar has been extensively studied, little is certain about the gateway dynamics leading up to the Messinian Salinity Crisis. Knowledge of the behavior of these corridors would be important to be able to link observations (e.g., sedimentary record, faunal or isotope studies) to the corresponding gateway geometries. The objective of this work is to gain physics-based understanding into the role of the interplay of the depth of the two gateways on the Atlantic-Mediterranean water exchange before the Salinity Crisis. To this end we use the regional ocean circulation model SbPOM, which is a parallel version of the Princeton Ocean Model, and Upper Tortonian palaeogeography. The experiments cover systematically various shoaling sequences ranging from relatively deep to closed corridors. Our results do not support the classic "siphon theory" proposed by Benson et al. (1991) for a double gateway scenario prior to the Messinian Salinity Crisis. These authors suggest unidirectional flow from the Atlantic into the Mediterranean via the Rifian corridor and Mediterranean outflow through the Betic one. In contrast, we find that different flow configurations are possible depending on the depth of one corridor relative to the other. More specifically, when one corridor is shallower than approximately half the depth of the other one, there is one-way flow through the shallow corridor and two-way flow in the deep one. In contrast, when one

    Full Text Available Globally, blended learning (BL technologies have been increasingly applied in a variety of fields, both public and private sectors. In recent years, universities, public and private businesses and organizations are among those employing blended learning methods and technologies in training and re-training of professionals in the workforce. In Malaysia, the increasing use of blended learning to enhance learning and enriching of soft skills among professionals and individuals in the work place is evident. The advancement of technology is an onset to many new avenues and tool for learning and teaching, and it is the coalescing of these various technologies with particular pedagogy or andragogy has helped to popularize BL. However, when an institution makes the critical choice of delivery methods, it is pertinent that the university needs to consider various success factors. One in particular is student-centered approach that entails the need to understand the students as the beneficiary of learning, and the support system they need to help them learn. This qualitative study reports in detail the experience of a small group of students undertaking Executive Diplomas at Executive Development Centre (EDC, Universiti Utara Malaysia as they progress through their Executive program. This paper looks at learning experiences as described by the learners- it is their story, their experience, and their perspective. This study suggests that BL offered a comfortable middle ground, and has lots of potential in higher education in Malaysia. It is a pedagogical alternative that could play a significant role not only for teaching Business Communication, but has the potential to promote lifelong learning initiatives in Malaysia in a much meaningful and inviting way. Although this study shows that BL contributed a significant and meaningful learning particularly for adult learners, it needs more definitive studies. Such information can be used to guide policy makers

    Mesoporous catalysts with enhanced oxygen reduction reaction (ORR) activity for PEM fuel cells are synthesized by alternating sputtering of Pt and Co onto gas diffusion layers with microporous layers. Co is acting as a template for synthesis of a porous Pt nanostructure. For such proposed Pt-Co catalysts the kinetic current in the ORR was found to be increased by a factor of up to 16 and the mass specific current in PEM single cells by a factor of up to 7. Co was found to be deposited at the grain boundary of the Pt layer and dissolves under acidic conditions resulting in a mesoporous Pt catalyst which is advantageous for gas diffusion catalysts. Microstructural and compositional parameters were optimised in order to obtain a high kinetic current and lower onset potential for the ORR. The most favourable Co layer thickness was determined to be 2 nm. The optimal Pt-Co catalyst can be synthesized by continuously varying the Pt layer thickness. The highest Pt mass activity was found at a layer thickness of 30.5 nm. Catalysts were characterised by SEM, EDX, electrochemical half cell and PEM single cell tests.

    This quasi-experimental study examined the effects of the Promoting Alternative Thinking Strategies (PATHS) Preschool Program on the outcomes of children's social-emotional competence, perceived relationships between teacher and children and teachers' ability to create a positive classroom atmosphere. Two hundred and eighty five children (48-72 months) and teachers in Izmir participated in the intervention, and 280 children (48-72 months) and teachers participated as comparison group. Intervention teachers implemented PATHS in their classrooms. For data triangulation, multiple sources of data were collected in the study. Classrooms were observed using two different scales. Teacher rated students using another two different scales. Children were assessed with an interview to evaluate their perceptions of relationships. Intervention group teachers reported greater improvement of children's social-emotional skills, interpersonal relationship skills and emotion regulation. Furthermore, when observed intervention group children showed higher levels of pro-social behaviour, increased levels of compliance, better problem solving skills and more positive feelings. Intervention group children also described their relationships with their teachers as significantly more positively. Finally, intervention group teachers perceived more dependency in their relationships with children. © 2017 International Union of Psychological Science.

    Learning how to use a computer-based communication system can be challenging for people with severe aphasia even if the system is not word-based. This study explored cognitive and linguistic factors relative to how they affected individual patients’ ability to communicate expressively using C-Speak Aphasia, (CSA), an alternative communication computer program that is primarily picture-based. Ten individuals with severe non-fluent aphasia received at least six months of training with CSA. To assess carryover of training, untrained functional communication tasks (i.e., answering autobiographical questions, describing pictures, making telephone calls, describing a short video, and two writing tasks) were repeatedly probed in two conditions: 1) using CSA in addition to natural forms of communication, and 2) using only natural forms of communication, e.g., speaking, writing, gesturing, drawing. Four of the ten participants communicated more information on selected probe tasks using CSA than they did without the computer. Response to treatment also was examined in relation to baseline measures of non-linguistic executive function skills, pictorial semantic abilities, and auditory comprehension. Only nonlinguistic executive function skills were significantly correlated with treatment response. PMID:21506045

    Alleviating the personal and social burden associated with substance use disorders requires the implementation of a comprehensive strategy, including outreach, education, community interventions, psychiatric treatment, and access to needle exchange programs (NEP), where peer support may be available. Given that substantial research underscores the potential benefits of peer support in psychiatric interventions, we aimed to conduct a national survey to examine key domains of mental health status in people who inject drugs (PWID) in New Zealand. PWID were recruited from 24 pharmacies and 16 dedicated peer-based needle exchanges (PBNEs) across the country. We focused on two mental health outcomes: (1) affective dysregulation, across the three emotional domains of the Depression Anxiety Stress Scale, due to its role in the maintenance of continued drug use, and (2) positive cognition and effective health- and drug-related information exchange with the provider, using the Satisfaction with Life Scale and an ad hoc questionnaire, respectively, in view of their association with improved mental health outcomes. We hypothesized that access to peer support would be associated with mental health benefits for PWIDs. Remarkably, the results of a multistep regression analysis revealed that irrespective of sex, age, ethnicity, main drug used, length of drug use, and frequency of visits to the NEP, the exclusive or preferential use of PBNEs predicted significantly lower depression and anxiety scores, greater satisfaction with life, and increased health-related information exchange with the service provider. These findings demonstrate for the first time an association between access to peer support at PBNEs and positive indices of mental health, lending strong support to the effective integration of such peer-delivered NEP services into the network of mental health services for PWID worldwide.

    Infectious disease remains a significant social and health concern in the United States. Preventing more people from contracting HIV/AIDS or Hepatitis C (HCV), requires a complex understanding of the interconnection between the biomedical and social dimensions of infectious disease. Opiate addiction in the US has skyrocketed in recent years. Preventing more cases of HIV/AIDS and HCV will require dealing with the social determinants of health. Needle exchange programs (NEPs) are based on a harm reduction approach that seeks to minimize the risk of infection and damage to the user and community. This article presents an exploratory small-scale quantitative study of the injection drug using habits of a group of injection drug users (IDUs) at a needle exchange program in Fresno, California. Respondents reported significant decreases in high risk IDU behaviors, including sharing of needles and to a lesser extent re-using of needles. They also reported frequent use of clean paraphernalia. Greater collaboration between social and health outreach professionals at NEPs could provide important frontline assistance to people excluded from mainstream office-based services and enhance efforts to reduce HIV/AIDS or HCV infection.

    This paper uses concepts from social networks and social exchange theories to describe the implementation of evidence-based practices in afterschool programs. The members of the LEGACY Together Afterschool Project team have been involved in conducting collaborative research to migrate a behavioral strategy that has been documented to reduce disruptive behaviors in classroom settings to a new setting-that of afterschool programs. We adapted the Paxis Institute's version of the Good Behavior Game to afterschool settings which differ from in-school settings, including more fluid attendance, multiple age groupings, diverse activities that may take place simultaneously, and differences in staff training and experience (Barrish et al. in J Appl Behav Anal 2(2):119-124, 1969; Embry et al. in The Pax Good Behavior Game. Hazelden, Center City, 2003; Hynes et al. in J Child Serv 4(3):4-20, 2009; Kellam et al. in Drug Alcohol Depend 95:S5-S28, 2008; Tingstrom et al. in Behav Modif 30(2):225-253, 2006). This paper presents the experiences of the three adult groups involved in the implementation process who give first-person accounts of implementation: (1) university-based scientist-practitioners, (2) community partners who trained and provided technical assistance/coaching, and (3) an afterschool program administrator. We introduce here the AIMS model used to frame the implementation process conceptualized by this town-gown collaborative team. AIMS builds upon previous work in implementation science using four phases in which the three collaborators have overlapping roles: approach/engagement, implementation, monitoring, and sustainability. Within all four phases principles of Social Exchange Theory and Social Network Theory are highlighted.

    Our current understanding of terrestrial carbon processes is represented in various models used to integrate and scale measurements of CO{sub 2} exchange from remote sensing and other spatiotemporal data. Yet assessments are rarely conducted to determine how well models simulate carbon processes across vegetation types and environmental conditions. Using standardized data from the North American Carbon Program we compare observed and simulated monthly CO{sub 2} exchange from 44 eddy covariance flux towers in North America and 22 terrestrial biosphere models. The analysis period spans {approx}220 site-years, 10 biomes, and includes two large-scale drought events, providing a natural experiment to evaluate model skill as a function of drought and seasonality. We evaluate models' ability to simulate the seasonal cycle of CO{sub 2} exchange using multiple model skill metrics and analyze links between model characteristics, site history, and model skill. Overall model performance was poor; the difference between observations and simulations was {approx}10 times observational uncertainty, with forested ecosystems better predicted than nonforested. Model-data agreement was highest in summer and in temperate evergreen forests. In contrast, model performance declined in spring and fall, especially in ecosystems with large deciduous components, and in dry periods during the growing season. Models used across multiple biomes and sites, the mean model ensemble, and a model using assimilated parameter values showed high consistency with observations. Models with the highest skill across all biomes all used prescribed canopy phenology, calculated NEE as the difference between GPP and ecosystem respiration, and did not use a daily time step.

  2. Microscale Regenerative Heat Exchanger

    The device described herein is designed primarily for use as a regenerative heat exchanger in a miniature Stirling engine or Stirling-cycle heat pump. A regenerative heat exchanger (sometimes called, simply, a "regenerator" in the Stirling-engine art) is basically a thermal capacitor: Its role in the Stirling cycle is to alternately accept heat from, then deliver heat to, an oscillating flow of a working fluid between compression and expansion volumes, without introducing an excessive pressure drop. These volumes are at different temperatures, and conduction of heat between these volumes is undesirable because it reduces the energy-conversion efficiency of the Stirling cycle.

  3. Cryptographic Combinatorial Securities Exchanges

    Science.gov (United States)

    Thorpe, Christopher; Parkes, David C.

    We present a useful new mechanism that facilitates the atomic exchange of many large baskets of securities in a combinatorial exchange. Cryptography prevents information about the securities in the baskets from being exploited, enhancing trust. Our exchange offers institutions who wish to trade large positions a new alternative to existing methods of block trading: they can reduce transaction costs by taking advantage of other institutions’ available liquidity, while third party liquidity providers guarantee execution—preserving their desired portfolio composition at all times. In our exchange, institutions submit encrypted orders which are crossed, leaving a “remainder”. The exchange proves facts about the portfolio risk of this remainder to third party liquidity providers without revealing the securities in the remainder, the knowledge of which could also be exploited. The third parties learn either (depending on the setting) the portfolio risk parameters of the remainder itself, or how their own portfolio risk would change if they were to incorporate the remainder into a portfolio they submit. In one setting, these third parties submit bids on the commission, and the winner supplies necessary liquidity for the entire exchange to clear. This guaranteed clearing, coupled with external price discovery from the primary markets for the securities, sidesteps difficult combinatorial optimization problems. This latter method of proving how taking on the remainder would change risk parameters of one’s own portfolio, without revealing the remainder’s contents or its own risk parameters, is a useful protocol of independent interest.

    This study explores the acceptability, the barriers to the implementation of needle and syringe exchange programs (NSPs) and the potential improvement strategies in China from the perspectives of governmental health and public security officials. Purposive sampling was used for recruitment of participants who had been involved in NSPs implementation. Semi-Structured individual interviews were conducted in Mandarin to address three aspects of NSPs: (1) participants' attitudes towards NSPs, (2) participants' opinions on the effectiveness and barriers of NSPs, and (3) suggestions for improving the program. Content analysis was used to analyse the translated interview data. A total of 68 participants from 12 Hunan counties were interviewed (34 from each of the Bureau of Health and the Narcotic Division). Both groups recognised the importance and effectiveness of NSPs in HIV prevention, but public security officials regarded NSPs as a temporary intervention in place of punitive measures. Most health officials (32/34) regarded the main barriers to its implementation as administrative and structural, whereas participants from Narcotics Division (n=24) questioned the legitimacy of NSPs and concerned about the poor management of drug users' risk behaviours. Close cooperation between the health and public security sectors, engagement of the drug user community and an enabling policy environment were reportedly to be critical for potential improvements of NSPs in China. Misconceptions about NSPs encourage drug users' addictive behaviour, and an unclear leadership and insufficient support de-motivate the participants from the Bureau of Health and the Narcotics Division to actively support the program implementation.

    Background There is growing concern about the human resources needed to care for increasing numbers of patients receiving antiretroviral therapy in resource-limited settings. We evaluated an alternative model, community-based, comprehensive antiretroviral program staffed primarily by peer health workers and nurses. Methods We conducted a retrospective cohort study of patients receiving antiretroviral therapy during the first 10 months of program enrollment beginning in late 2003. Virologic, immunologic, clinical, and adherence data were collected. Results Of 360 patients started on treatment, 258 (72%) were active and on therapy approximately two years later. Viral load testing demonstrated that 86% of active patients (211 of 246 tested) had a viral load <400 copies/mL. The median CD4 increase for active patients was 197 cells/mm3 (IQR, 108–346). Patients with either a history of antiretroviral use or lack of CD4 response were more likely to experience virologic failure. Survival was 84% at one year and 82% at two years. WHO stage 4 was predictive of both not sustaining therapy and increased mortality. Conclusions A community-based antiretroviral treatment program in a resource-limited setting can provide excellent AIDS care over at least a two year period. A comprehensive program based upon peer health workers and nurses provides an effective alternative model for AIDS care. PMID:19194316

    2005-12-01

    Full Text Available Family strengthening has become a source of growing interest, research, and program design in the fields of prevention and treatment for problems of youth delinquency, school failure, alcohol, tobacco and other drug abuse (ATOD. Despite many studies that illustrate the positive outcomes of family strengthening programs and family-focused interventions, their use in communities has not advanced commensurate with their promise. This article offers a rationale for why programming efforts should continue to be directed towards family strengthening efforts as opposed to youth-focused only interventions. In addition, a community-based, family-strengthening alternative is described that addresses issues of youth delinquency while reducing barriers associated with availability, accessibility, and cost.

    This report summarizes the Phase I research and development work performed during the March 13, 2015 to July 13, 2016 period. The proposal for this work was submitted in response to NASA Research Announcement NNH14ZOA001N, "Space Technology Research, Development, Demonstration, and Infusion 2014 (SpaceTech-REDDI-2014)," Appendix 14GCD-C2 "Game Changing Development Program, Advanced Oxygen Recovery for Spacecraft Life Support Systems Appendix" The Task Agreement for this Phase I work is Document Control Number: GCDP-02-TA-15015. The objective of the Phase I project was to demonstrate in laboratories two Engineering Development Units (EDU) that perform critical functions of the low temperature carbon dioxide electrolysis and the catalytic conversion of carbon monoxide into carbon and carbon dioxide. The low temperature carbon dioxide electrolysis EDU was built by the University of Delaware with Dr. Feng Jiao as the principal investigator in charge of this EDU development (under NASA Contract NNC15CA04C). The carbon monoxide catalytic conversion EDU was built by the NASA Glenn Research Center with Kenneth Burke as the principal investigator and overall project leader for the development of both EDUs. Both EDUs were successfully developed and demonstrated the critical functions for each process. The carbon dioxide electrolysis EDU was delivered to the NASA Johnson Space Center and the carbon monoxide catalytic conversion EDU was delivered to the NASA Marshall Spaceflight Center.

    Energy Technology Data Exchange (ETDEWEB)

    None

    1979-12-01

    The purpose of this volume is to assess the proliferation vulnerabilities of the present deployment of civilian nuclear-power systems within the current nonproliferation regime and, in light of their prospective deployment, to consider technical and institutional measures and alternatives which may contribute to an improved regime in which nuclear power could play a significant part. An assessment of these measures must include consideration of their nonproliferation effectiveness as well as their bearing upon energy security, and their operational, economic, and political implications. The nature of these considerations can provide some measure of their likely acceptability to various nations. While any final assessment of such measures and alternatives would have to examine the circumstances particular to each nation, it is hoped that the more generic assessments conducted here will be useful in suggesting guidelines for developing an improved nonproliferation regime which also helps to meet nuclear-energy needs. One chapter outlines the existing nonproliferation regime, including the Treaty for the Non-Proliferation of Nuclear Weapons (NPT), International Atomic Energy Agency (IAEA) safeguards, bilateral and multilateral requirements for agreements of cooperation and transfers of technology, and existing provisons for sanctions for violation of nonproliferation commitments. The chapter then proceeds to an assessment of various alternatives for providing assurance of fuel supply in light of this current regime. Another chapter examines a set of technical and institutional measures and alternatives for various components of once-through and closed fuel cycles. The components of the once-through fuel cycle assessed are enrichment services and spent-fuel management; the components of closed fuel cycles assessed are reprocessing and plutonium management and fast-breeder reactor (FBR) deployment.

    Vixen is a collection of enabling technologies for uninhibited distributed object computing. In the Spring of 1995 when Vixen was proposed, it was an innovative idea very much ahead of its time. But today the technologies proposed in Vixen have become standard technologies for Enterprise Computing. Sun Microsystems J2EE/EJB specifications, among others, are independently proposed technologies of the Vixen type. I have brought Vixen completely under the J2EE standard in order to maximize interoperability and compatibility with other computing industry efforts. Vixen and the Enterprise JavaBean (EJB) Server technologies are now practically identical; OIL, another Vixen technology, and the Java Messaging System (JMS) are practically identical; and so on. There is no longer anything novel or patentable in the Vixen work performed under this grant. The above discussion, notwithstanding, my independent development of Vixen has significantly helped me, my university, my students and the local community. The undergraduate students who worked with me in developing Vixen have enhanced their expertise in what has become the cutting edge technology of their industry and are therefore well positioned for lucrative employment opportunities in the industry. My academic department has gained a new course: "Multi-media System Development", which provides a highly desirable expertise to our students for employment in any enterprise today. The many Outreach Programs that I conducted during this grant period have exposed local Middle School students to the contributions that NASA is making in our society as well as awakened desires in many such students for careers in Science and Technology. I have applied Vixen to the development of two software packages: (a) JAS: Joshua Application Server - which allows a user to configure an EJB Server to serve a J2EE compliant application over the world wide web; (b) PCM: Professor Course Manager: a J2EE compliant application for configuring a

    2013-01-01

    In Next Generation Microchannel Heat Exchangers, the authors’ focus on the new generation highly efficient heat exchangers and presentation of novel data and technical expertise not available in the open literature.  Next generation micro channels offer record high heat transfer coefficients with pressure drops much less than conventional micro channel heat exchangers. These inherent features promise fast penetration into many mew markets, including high heat flux cooling of electronics, waste heat recovery and energy efficiency enhancement applications, alternative energy systems, as well as applications in mass exchangers and chemical reactor systems. The combination of up to the minute research findings and technical know-how make this book very timely as the search for high performance heat and mass exchangers that can cut costs in materials consumption intensifies.

    Jensen, Pernille Foged; Rand, Kasper Dyrberg

    2016-01-01

    Hydrogen exchange (HX) monitored by mass spectrometry (MS) is a powerful analytical method for investigation of protein conformation and dynamics. HX-MS monitors isotopic exchange of hydrogen in protein backbone amides and thus serves as a sensitive method for probing protein conformation...... and dynamics along the entire protein backbone. This chapter describes the exchange of backbone amide hydrogen which is highly quenchable as it is strongly dependent on the pH and temperature. The HX rates of backbone amide hydrogen are sensitive and very useful probes of protein conformation......, as they are distributed along the polypeptide backbone and form the fundamental hydrogen-bonding networks of basic secondary structure. The effect of pressure on HX in unstructured polypeptides (poly-dl-lysine and oxidatively unfolded ribonuclease A) and native folded proteins (lysozyme and ribonuclease A) was evaluated...

    Augmentative and alternative communication (AAC) promotes communicative participation and language development for young children with complex communication needs. However, the motor, linguistic, and cognitive demands of many AAC technologies restrict young children's operational use of and influence over these technologies. The purpose of the current study is to better understand young children's participation in programming vocabulary "just in time" on an AAC application with minimized demands. A descriptive study was implemented to highlight the participation of 10 typically developing toddlers (M age: 16 months, range: 10-22 months) in just-in-time vocabulary programming in an AAC app with visual scene displays. All 10 toddlers participated in some capacity in adding new visual scene displays and vocabulary to the app just in time. Differences in participation across steps were observed, suggesting variation in the developmental demands of controls involved in vocabulary programming. Results from the current study provide clinical insights toward involving young children in AAC programming just in time and steps that may allow for more independent participation or require more scaffolding. Technology designed to minimize motor, cognitive, and linguistic demands may allow children to participate in programming devices at a younger age.

    Over one-third of U.S. medical schools offer combined baccalaureate/MD (BA/MD) degree programs. A subset of these truncate the premedical phase, reducing total time to the MD degree. Data comparing educational outcomes of these programs with those of conventional pathways are limited. The authors reviewed demographic characteristics and medical school performance of all 2,583 students entering Northwestern University Feinberg School of Medicine from 1999 to 2013, comparing students in the Honors Program in Medical Education (HPME), an accelerated seven-year program, versus non-HPME medical students. They evaluated Alpha Omega Alpha (AOA) selection, quintile performance distribution from the Medical Student Performance Evaluation, United States Medical Licensing Examination (USMLE) scores, and Match outcomes. A total of 560 students (21.7%) entered through the HPME. HPME students were on average 2.2 years younger and less likely (15/537 [2.8%] versus 285/1,833 [15.5%]) to belong to a racial/ethnic group underrepresented in medicine. There were no significant differences in AOA selection, quintile performance distribution, or USMLE scores. More HPME students entered internal medicine (161/450 [35.8%] versus 261/1,265 [20.6%]), and fewer chose emergency medicine (25/450 [5.6%] versus 110/1,265 [8.7%]) and obstetrics-gynecology (9/450 [2.0%] versus 67/1,265 [5.3%]). The academic performances of medical students in the two programs studied were equivalent. Accelerated BA/MD programs might play a role in ameliorating the length and cost of a medical education. The academic success of these students absent the usual emphasis on undergraduate GPA and Medical College Admission Test scores supports efforts to redefine medical student selection criteria.

  13. Alternative additives; Alternative additiver

    Energy Technology Data Exchange (ETDEWEB)

    2007-08-15

    In this project a number of industrial and agricultural waste products have been characterised and evaluated in terms of alkali-getter performance. The intended use is for biomass-fired power stations aiming at reducing corrosion or slagging related problems. The following products have been obtained, characterised and evaluated: 1) Brewery draff 2) Danish de-gassed manure 3) Paper sludge 4) Moulding sand 5) Spent bleaching earth 6) Anorthosite 7) Sand 8) Clay-sludge. Most of the above alternative additive candidates are deemed unsuitable due to insufficient chemical effect and/or expensive requirements for pre-treatment (such as drying and transportation). 3 products were selected for full-scale testing: de-gassed manure, spent bleaching earth and clay slugde. The full scale tests were undertaken at the biomass-fired power stations in Koege, Slagelse and Ensted. Spent bleaching earth (SBE) and clay sludge were the only tested additive candidates that had a proven ability to react with KCl, to thereby reduce Cl-concentrations in deposits, and reduce the deposit flux to superheater tubes. Their performance was shown to nearly as good as commercial additives. De-gassed manure, however, did not evaluate positively due to inhibiting effects of Ca in the manure. Furthermore, de-gassed manure has a high concentration of heavy metals, which imposes a financial burden with regard to proper disposal of the ash by-products. Clay-sludge is a wet clay slurring, and drying and transportation of this product entails substantial costs. Spent bleaching does not require much pre-treatment and is therefore the most promising alternative additive. On the other hand, bleaching earth contains residual plant oil which means that a range of legislation relating to waste combustion comes into play. Not least a waste combustion fee of 330 DKK/tonne. For all alternative (and commercial) additives disposal costs of the increase ash by-products represents a significant cost. This is

  14. Alternative Labeling Programs and Purchasing Behavior toward Organic Foods: The Case of the Participatory Guarantee Systems in Brazil

    Full Text Available Regulatory standards and certification models are essential tools guaranteeing the authenticity of organic products. In particular, third-party certification is useful to consumers since it provides guarantees regarding production processes and food quality. In an attempt to cope with the costs and bureaucratic procedures related to the adoption of such certification, groups of small producers have begun to rely upon alternative quality assurance systems such as Participatory Guarantee Systems (PGS. This study contextualizes and analyzes the PGS scheme and describes the Brazilian Rede Ecovida de Agroecologia network. We then investigate the effect of various factors on Brazilian consumers’ purchasing behavior for organic products guaranteed by PGS. The results show that employed and older consumers who live in rural and suburban areas are more likely to buy organic PGS products.

    Energy Technology Data Exchange (ETDEWEB)

    1980-06-01

    The purpose of this volume is limited to an assessment of the relative effects that particular choices of nuclear-power systems, for whatever reasons, may have on the possible spread of nuclear-weapons capabilities. This volume addresses the concern that non-nuclear-weapons states may be able to initiate efforts to acquire or to improve nuclear-weapons capabilities through civilian nuclear-power programs; it also addresses the concern that subnational groups may obtain and abuse the nuclear materials or facilities of such programs, whether in nuclear-weapons states (NWS's) or nonnuclear-weapons states (NNW's). Accordingly, this volume emphasizes one important factor in such decisions, the resistance of nuclear-power systems to the proliferation of nuclear-weapons capabilities.

    Volume IV provides time and cost estimates for positioning new nuclear power systems for commercial deployment. The assessment also estimates the rates at which the new systems might penetrate the domestic market, assuming the continuing viability of the massive light-water reactor network that now exists worldwide. This assessment does not recommend specific, detailed program plans and budgets for individual systems; however, it is clear from this analysis that any of the systems investigated could be deployed if dictated by national interest.

    Evaluation of effects of mass media-based health interventions requires accurate assessments of exposure, which can be difficult to obtain when young children are the primary audience. Alam Simsim, the Egyptian version of Sesame Street, aired nationally in Egypt to teach preschoolers about numeracy, literacy, and gender-equitable attitudes. The purpose of this article was to assess the effect of the program through a first-of-its-kind household-level survey that interviewed caretakers (n = 426) and preschoolers (n = 486). The authors introduced and tested the efficacy of a parsimonious measure of exposure: children's recognition of the primary characters of the program. Overall, the authors' models explained as much as 53% of the variance in children's learning; exposure to the program was significantly associated with learning. Furthermore, the parsimonious measure of exposure was as effective as a more elaborate child-reported measure. Relative to these two measures of exposure, caretakers' report of children's viewing was not as good a predictor of learning.

    Fracassini, Massimo; Pasinetti Fracassini, Laura E.; Pasinetti, Antonio L.

    1988-07-01

    The Anthropic Principle, a new trend of modern cosmology, claims that the origin of life and the development of intelligent beings on the Earth is the result of highly selective biological processes, strictly tuned in the fundamental physical characteristics of the Universe. This principle could account for the failure of some programs of search for extraterrestrial intelligences (SETI) and suggests the search for strict solar analogs as a primary target for SETI strategies. In this connection, the authors have selected 22 solar analogs and discussed their choice.

    Women who inject drugs (WWID) are at heightened risk for HIV due to biological, behavioral, and structural factors. Pre-exposure prophylaxis (PrEP) could aid in HIV prevention for WWID. However, little is known about WWID awareness of PrEP, which is a necessary step that must occur before PrEP uptake. We report factors associated with greater awareness among WWID to identify efficient means of awareness dissemination. Data from the 2015 National HIV Behavioral Surveillance (NHBS) system cycle on injection drug use collected in New York City (NYC) were used. Bivariable analyses, using chi-squared statistics, were conducted to examine correlates of awareness of PrEP with socio-demographic, behavioral, and health care variables. Multivariable logistic regression was used to estimate adjusted associations and determine differences in awareness of PrEP. The analysis consisted of 118 WWID. Awareness of PrEP was relatively low (31%), and risk factors were high. In the last 12 months, almost two thirds (65%) reported condomless sex, approximately one third (31%) reported transactional sex, and one third (32%) reported sharing injection equipment. In multivariable logistic regression, increased PrEP awareness was associated with reported transactional sex (AOR 3.32, 95% CI 1.22-9.00) and having a conversation about HIV prevention at a syringe exchange program (SEP) (AOR 7.61, 95% CI 2.65-21.84). We did not find race, education, household income, age, binge drinking, or sexual identity to be significantly associated with PrEP awareness. Large proportions of WWID were unaware of PrEP. These findings suggest that social networks (specifically sex work and SEP networks) are an efficient means for disseminating messaging about prevention materials such as PrEP. We recommend that SEP access increase, SEP processes be adopted in other health care settings, and WWID networks be utilized to increase PrEP awareness.

    Full Text Available Abstract Recent data suggest that globally, between 5% and 10% of all new HIV cases are the result of unsafe injecting practices, and experts agree that reducing these practices is key to tackling the spread of HIV. And yet, despite the overwhelming evidence that providing sterile syringes to injection drug users (IDU through syringe exchange programs (SEPs or other means is an effective way of reducing HIV transmission among high-risk subpopulations, IDU in most settings still do not have access to sterile injecting equipment or if they do, access remains too restricted to effectively reduce the risk of HIV transmission. Vorobjov and colleagues have presented in this journal an interesting and timely study from Estonia comparing individuals who obtain syringes from SEPs and those who obtain syringes from pharmacies. As the authors point out, Estonia faces an unacceptably high HIV incidence rate of 50 new HIV cases per 100,000, this rate driven primarily by injection drug use. As such, the authors argue that Estonia's SEP network does not have the capacity to serve a growing IDU population at risk of transmitting HIV and pharmacy dispensation of clean syringes may be one potential approach to decreasing syringe sharing among high-risk injectors. It may be overly optimistic to consider the impact of higher threshold interventions such as pharmacy-based SEPs, given that IDU populations that engage in HIV risk behaviours such as syringe sharing are often hidden or hard to reach. Despite the need for a cautious approach, however, the findings presented by Vorobjov et al. may chart one potential course towards a more comprehensive societal response to reducing the health harms associated with injection drug use.

    For the promotion of research exchanges on global environmental preservation with developing countries, Ms. Malee Santikunaporn, lecturer of Faculty of Engineering, Thammasat University, Bankok, Thailand was invited. Desulfurization/denitrification facilities, which are being widely spread in developed countries, have marked effects, but high prices are an obstacle to the spread in developing countries. To make them spread in developing countries, it is needed to develop the technology which is low in price and meets the actual state in developing countries. As a technology with high viability, a system to simultaneously remove SOx and NOx was cited in which Cu is used as catalyst and adsorbent and into which the catalyst regeneration process is integrated. Considering it, technical exchanges on Cu-SiO{sub 2} catalyst as the basic theme were made during September 26 - December 23, 1999. Through visits on and exchanges with Tokyo Institute of Technology, ICEET, University of Kyoto, etc., understanding was deepened about how each country is tackling environmental problems. The theme 'Oxidative sorption of SO2 by Cu-SiO{sub 2} catalyst: characteristics of catalyst' could deepen knowledge/information of the developmental research as a system for simultaneous removal of SOx/NOx. The data obtained indicated great practicality of Cu-SiO{sub 2}. (NEDO)

    Chronic pain remains an enigma which mystifies the most experienced clinicians. The traditional approaches to malignant pain employ narcotic analgesics, radiotherapy, surgical intervention, and chemotherapy. Within the context of a "therapeutic community" oriented pain unit, we attack this major public health problem differently. The use of non-narcotic analgesics, mood altering medications, various forms of psychotherapy (individual, group, family, gestalt, psychomotor) and peer pressure when used in conjunction with various physical modalities of treatment (including biofeedback, transcutaneous electrical nerve stimulator, physical therapy, whirlpool, massage, ice, heat, etc.) appear most efficacious. Frequently, the powerful tools of psychological medicine are taken for granted; yet, depression in the United States is widespread and so significantly complicates medical illness that any treatment program designed for pain patients must be holistic in its orientation if it is to be effective.

    The authors have investigated the possibility of collecting different aldehydes and ketones on different sorbents such as silica gel, molecular sieve and charcoal followed by solvent extraction, DNPH derivatization and HPLC/UV analysis. Carbonyl collection efficiencies for these sorbents were calculated relative to a DNPH coated C{sub 18} sep-pak cartridge. From a limited number of laboratory experiments, at various concentrations, it appears that silica gel tubes can be used for sampling aldehydes (collection efficiencies {approximately} 1), whereas charcoal tubes are suitable for collecting ketones. Molecular sieve was found to be unsuitable for collecting most of the carbonyl studied. The authors also report the development of a fully automated 24-port carbonyl sampler specially designed for EPA`s PAMS program.

    An experimental program examining the interaction between several fuel and light duty automotive engine combinations is detailed. Combustion systems addressed covered indirect and direct injection diesel and spark ignited stratified charge. Fuels primarily covered D2, naphtha and intermediate broadcut blends. Low ignition quality diesel fuels were also evaluated. The results indicate the baseline fuel tolerance of each combustion system and enable characteristics of the systems to be compared. Performance, gaseous and particulate emissions aspects were assessed. The data obtained assists in the selection of candidate combustion systems for potential future fuels. Performance and environmental penalties as appropriate are highlighted relative to the individual candidates. Areas of further work for increased understanding are also reviewed.

    This project seeks to improve the efficiency of the plutonium anion-exchange process for purifying Pu through the development of alternate ion-exchange media. The objective of the project in FY15 was to develop and test a porous foam monolith material that could serve as a replacement for the current anion-exchange resin, Reillex® HPQ, used at the Savannah River Site (SRS) for purifying Pu. The new material provides advantages in efficiency over the current resin by the elimination of diffusive mass transport through large granular resin beads. By replacing the large resin beads with a porous foam there is much more efficient contact between the Pu solution and the anion-exchange sites present on the material. Several samples of a polystyrene based foam grafted with poly(4-vinylpyridine) were prepared and the Pu sorption was tested in batch contact tests.

    2008-07-01

    Energy supply and use is of fundamental importance to society. Although the interactions between energy and environment were originally local in character, they have now widened to cover regional and global issues, such as acid rain and the greenhouse effect. It is for this reason that there is a need for covering the direct and indirect economic and environmental impacts of energy acquisition, transport, production and use. In this paper, particular attention is directed to ways of resolving conflict between economic and environmental goals by encouraging a power plant to consider co-firing biomass and refuse-derived fuel (RDF) with coal simultaneously. It aims at reducing the emission level of sulfur dioxide (SO(2)) in an uncertain environment, using the power plant in Michigan City, Indiana as an example. To assess the uncertainty by a comparative way both deterministic and grey nonlinear mixed integer programming (MIP) models were developed to minimize the net operating cost with respect to possible fuel combinations. It aims at generating the optimal portfolio of alternative fuels while maintaining the same electricity generation simultaneously. To ease the solution procedure stepwise relaxation algorithm was developed for solving the grey nonlinear MIP model. Breakeven alternative fuel value can be identified in the post-optimization stage for decision-making. Research findings show that the inclusion of RDF does not exhibit comparative advantage in terms of the net cost, albeit relatively lower air pollution impact. Yet it can be sustained by a charge system, subsidy program, or emission credit as the price of coal increases over time.

  12. Teacher Identity and Self-efficacy Development in an Alternative Licensure Program for Middle and High School Math and Science Teachers

    Science.gov (United States)

    West, Robert J.

    This mixed-method case study focused on the phenomenon of the transition from student to teacher. The educational system in the United States is constantly shifting to provide the correct number of teachers for our nations' schools. There is no simple formula for this process and occasionally an area of need arises that is not being met. Recently, the demand for science and math teachers in the K-12 system has outpaced the supply of new teachers (Business-Higher Education Forum, 2011). To complicate the problem further, teachers are leaving the field in record numbers both through retirement and attrition (National Commission on Teaching and America's Future, 2007). Particularly hard hit are poor rural schools with low-performing students, such as the schools of Appalachia (Barley, 2009; Goodpaster, Adedokun, & Weaver, 2012). Out of this need, alternative licensure programs for teachers have developed. The alternative teacher-training program studied in this research is the Woodrow Wilson Teaching Fellowship (WWTF) website, "The Woodrow Wilson Ohio Teaching Fellowship seeks to attract talented, committed individuals with backgrounds in the STEM fields---science, technology, engineering, and mathematics---into teaching in high-need Ohio secondary schools" (para. 2) . The researcher was interested in the formation of teacher identity and self-efficacy as these constructs have been shown to manifest in highly effective teachers that are likely to remain in the field of teaching (Beaucamp & Thomas 2009; Klassen, Tze, Betts, & Gordon, 2010). The research method included in-depth interviews, mixed with pretest/posttest administrations of the Teacher Sense of Efficacy Scale (TSES) (Tschannen-Moran & Woolfolk Hoy 2001) given during the teacher-training period and again following the first year of professional teaching. Results from both the TSES and the interviews indicate that the participants had a successful transition into teaching. They both felt and demonstrated that

    Full Text Available Abstract Background Landmark based geometric morphometrics (GM allows the quantitative comparison of organismal shapes. When applied to systematics, it is able to score shape changes which often are undetectable by traditional morphological studies and even by classical morphometric approaches. It has thus become a fast and low cost candidate to identify cryptic species. Due to inherent mathematical properties, shape variables derived from one set of coordinates cannot be compared with shape variables derived from another set. Raw coordinates which produce these shape variables could be used for data exchange, however they contain measurement error. The latter may represent a significant obstacle when the objective is to distinguish very similar species. Results We show here that a single user derived dataset produces much less classification error than a multiple one. The question then becomes how to circumvent the lack of exchangeability of shape variables while preserving a single user dataset. A solution to this question could lead to the creation of a relatively fast and inexpensive systematic tool adapted for the recognition of cryptic species. Conclusions To preserve both exchangeability of shape and a single user derived dataset, our suggestion is to create a free access bank of reference images from which one can produce raw coordinates and use them for comparison with external specimens. Thus, we propose an alternative geometric descriptive system that separates 2-D data gathering and analyzes.

    Full Text Available This study examines how homeschooling, unschooling and alternative learners have been portrayed in five recent films and television programs. It also investigates whether the media are grounding their representations of these students and their parents in reality, or if it is disseminating harmful stereotypes that may have detrimental effects for those who choose to learn in this manner in real life.In the wake of numerous (and often misguided school reform efforts across North America and much of the developed world, many students and their parents have become disillusioned with traditional forms of formal education and find themselves turning to homeschooling, unschooling and other methods of alternative learning that have gained steam and a great deal of credibility over the past decade (Lloyd, 2009. Lloyd (2009 notes that approximately 1.5 million students in the United States of America are homeschooled, with 10-15% of that number representing unschoolers. Homeschooling is a term with which most are familiar. It refers to children who receive their education at home rather than in the confines of a formal classroom. Unschooling, which can differ greatly from homeschooling, is a term used to classify a range of educational philosophies and practices predicated on allowing children to learn through life experience, play and social interaction without being forced to perform tasks by interfering adults (Ricci, 2009, p. 12. While these are two separate and competing educational philosophies, they have been lumped together for the purposes of this paper as the media texts used as the data sources for this study often blur the boundaries between these methods of learning. After a brief exploration of media culture and the ever increasing influence that television and films are having as socialization agents in the lives of youth and adults alike, this study will investigate how students who pursue alternative forms of learning are being

    1979-12-01

    The Nonproliferation Alternative Systems Assessment Program (NASAP) has characterized and assessed various reactor/fuel-cycle systems. Volume IX provides, in summary form, the technical descriptions of the reactor/fuel-cycle systems studied. This includes the status of the system technology, as well as a discussion of the safety, environmental, and licensing needs from a technical perspective. This information was then used in developing the research, development, and demonstration (RD and D) program, including its cost and time frame, to advance the existing technology to the level needed for commercial use. Wherever possible, the cost data are given as ranges to reflect the uncertainties in the estimates. Volume IX is divided into three sections: Chapter 1, Reactor Systems; Chapter 2, Fuel-Cycle Systems; and the Appendixes. Chapter 1 contains the characterizations of the following 12 reactor types: light-water reactor; heavy-water reactor; water-cooled breeder reactor; high-temperature gas-cooled reactor; gas-cooled fast reactor; liquid-metal fast breeder reactor; spectral-shift-controlled reactor; accelerator-driven reactor; molten-salt reactor; gaseous-core reactor; tokamak fusion-fisson hybrid reactor; and fast mixed-spectrum reactor. Chapter 2 contains similar information developed for fuel-cycle facilities in the following categories: mining and milling; conversion and enrichment; fuel fabrication; spent fuel reprocessing; waste handling and disposal; and transportation of nuclear materials.

    Here we report that prioritizing sites in order of rarity-weighted richness (RWR) is a simple, reliable way to identify sites that represent all species in the fewest number of sites (minimum set problem) or to identify sites that represent the largest number of species within a given number of sites (maximum coverage problem). We compared the number of species represented in sites prioritized by RWR to numbers of species represented in sites prioritized by the Zonation software package for 11 datasets in which the size of individual planning units (sites) ranged from <1 ha to 2,500 km2. On average, RWR solutions were more efficient than Zonation solutions. Integer programming remains the only guaranteed way find an optimal solution, and heuristic algorithms remain superior for conservation prioritizations that consider compactness and multiple near-optimal solutions in addition to species representation. But because RWR can be implemented easily and quickly in R or a spreadsheet, it is an attractive alternative to integer programming or heuristic algorithms in some conservation prioritization contexts.

    Participation in external quality assessment programs is critical to ensure quality clinical laboratory testing. Commercially available proficiency test panels for HIV-1 virus load testing that are used commonly in external quality assessment programs remain a financial obstacle to resource-limited countries. Maintaining cold-chain transportation largely contributes to the cost of traditional liquid proficiency test panels. Therefore, we developed and evaluated a proficiency test panel using dried tube specimens that can be shipped and stored at ambient temperature. This dried tube specimens panel consisted of 20 μl aliquots of a HIV-1 stock that were added to 2 ml tubes and left uncapped for drying, as a preservation method. The stability of dried tube specimens at concentrations ranging from 10² to 10⁶·⁵ RNA copies/ml was tested at different temperatures over time, showing no viral load reduction at 37 °C and a decrease in viral load smaller than 0.5 Log₁₀ at 45 °C for up to eight weeks when compared to initial results. Eight cycles of freezing-thawing had no effect on the stability of the dried tube specimens. Comparable viral load results were observed when dried tube specimen panels were tested on Roche CAPTAQ, Abbott m2000, and Biomerieux easyMAG viral load systems. Preliminary test results of dried proficiency test panels shipped to four African countries at ambient temperature demonstrated a low inter assay variation (SD range: 0.29-0.41 Log₁₀ RNA copies/ml). These results indicated that HIV-1 proficiency test panels generated by this methodology might be an acceptable alternative for laboratories in resource-limited countries to participate in external quality assessment programs.

    The present review attempts to evaluate the importance of efficient equipment diffusion in reducing energy consumption, based upon the Study-case of an air conditioned exchange program in Manaus city of Amazonas. In spite of the existence, in the actual market, of efficient technology, it has been, yet, badly diffused, mostly due to economical and informative laps. Therefore, once tried to demonstrate the potential benefits, in technical gains, of energy efficiency offered by efficient Air conditioned equipment, through a plan that favors the consumer's participation as an active contributor in the dissemination process of efficient technology, and a following program for efficiency evaluation, beside a tributary evaluation proposal, so that technology becomes accessible to the general population, attempting its benefices. In addition, the environmental benefits of that specific proposal are analyzed, trough the developed recycling program. (author)

  5. Technology choice and development in Brazil: An assessment of Brazil's alternative fuel program and the agriculture, manufacturing, energy, and service sectors

    Science.gov (United States)

    Nolan, Lucy A.

    Technology choice profoundly affects a country's development process because capital-intensive and labor-intensive technologies have different socioeconomic linkages within the economy. This research examines the impacts of technology choice through the use of a social accounting matrix (SAM) framework. SAM-based modeling determines the direct and indirect effects of technology choice on development, particularly poverty alleviation in Brazil. Brazil's alternative fuel program was analyzed as a special example of technology choice. Two ethanol production technologies and the gasoline sector were compared; to make the study more robust, labor and capital intensive technologies were evaluated in the production of agriculture, manufacturing, energy, and services. Growth in these economic sectors was examined to assess the effects on employment, factor and household income, energy intensity, and carbon dioxide costs. Poverty alleviation was a focus, so income to unskilled agriculture labor, unskilled non-agriculture labor, and income to rural and urban households in poverty was also analyzed. The major research finding is that overall, labor-intensive technologies generate more employment, factor and household income, environmental and energy benefits to Brazil's economy than capital-intensive technologies. In addition, labor-intensive technologies make a particular contribution to poverty alleviation. The results suggest that policies to encourage the adoption of these technologies, especially in the agriculture and renewable energy sectors, are important because of their intersectoral linkages within the economy. Many studies have shown that Brazil's fuel ethanol program has helped to realize multiple macroeconomic objectives. However, this is the first empirical study to quantify its household income effects. The ethanol industry generated the most household income of the energy sectors. The research confirms a key finding of the appropriate technology literature

    Nutritional health is essential for children's growth and development. Many Mexican-origin children who reside in limited-resource colonias along the Texas-Mexico border are at increased risk for poor nutrition as a result of household food insecurity. However, little is known about the prevalence of child hunger or its associated factors among children of Mexican immigrants. This study determines the prevalence of child hunger and identifies protective and risk factors associated with it in two Texas border areas. This study uses 2009 Colonia Household and Community Food Resource Assessment (C-HCFRA) data from 470 mothers who were randomly recruited by promotora-researchers. Participants from colonias near two small towns in two South Texas counties participated in an in-home community and household assessment. Interviewer-administered surveys collected data in Spanish on sociodemographics, federal food assistance program participation, and food security status. Frequencies and bivariate correlations were examined while a random-effects logistic regression model with backward elimination was used to determine correlates of childhood hunger. Hunger among children was reported in 51% (n = 239) of households in this C-HCFRA sample. Bivariate analyses revealed that hunger status was associated with select maternal characteristics, such as lower educational attainment and Mexican nativity, and household characteristics, including household composition, reliance on friend or neighbor for transportation, food purchase at dollar stores and from neighbors, and participation in school-based nutrition programs. A smaller percentage of households with child hunger participated in school-based nutrition programs (51%) or used alternative food sources, while 131 households were unable to give their child or children a balanced meal during the school year and 145 households during summer months. In the random effects model (RE = small town), increased household

    With the purpose of promoting research exchanges with developing countries concerning preservation of the global environment, ICETT (International Center for Environmental Technology Transfer) invited two researchers from Center of Environmental Protection and Chemical Safety, Institute of Industrial Chemistry, Ministry of Industry, Vietnam. The period was from September 19 to December 17, 2000, and the subject was a basic research on environmentally friendly wastewater treatment technology utilizing bacteria in soils. In an experimental system, five reaction layers made of vinyl chloride tubes having a diameter of 16 cm and a height of 50 cm are serially connected, with a suitable filler used for each as a tank for precipitation of heavy metals and treatment of BOD, for anaerobic denitrification, for decomposition of aerobic COD, BOD, etc., for phosphorus treatment, and for bleaching (deodorizing), and with domestic wastewater treated through contact filtration. In spite of a limited period, from the obtained experimental results, the quality of water after the treatment was Class B or higher in the Japanese environmental standards for rivers, lakes and coastal waters, showing high practicability of this system. Further, some pieces of consideration were given additionally to the application in Vietnam. (NEDO)

    This research is focused on improving the efficiency of the anion exchange process for purifying plutonium. While initially focused on plutonium, the technology could also be applied to other ion-exchange processes. Work in FY17 focused on the improvement and optimization of porous foam columns that were initially developed in FY16. These foam columns were surface functionalized with poly(4-vinylpyridine) (PVP) to provide the Pu specific anion-exchange sites. Two different polymerization methods were explored for maximizing the surface functionalization with the PVP. The open-celled polymeric foams have large open pores and large surface areas available for sorption. The fluid passes through the large open pores of this material, allowing convection to be the dominant mechanism by which mass transport takes place. These materials generally have very low densities, open-celled structures with high cell interconnectivity, small cell sizes, uniform cell size distributions, and high structural integrity. These porous foam columns provide advantages over the typical porous resin beads by eliminating the slow diffusion through resin beads, making the anion-exchange sites easily accessible on the foam surfaces. The best performing samples exceeded the Pu capacity of the commercially available resin, and also offered the advantage of sharper elution profiles, resulting in a more concentrated product, with less loss of material to the dilute heads and tails cuts. An alternate approach to improving the efficiency of this process was also explored through the development of a microchannel array system for performing the anion exchange.

  16. Alternatives evaluation for the decontamination and decommissioning of buildings 3506 and 3515 at Oak Ridge National Laboratory, Oak Ridge, Tennessee. Environmental Restoration Program

    Energy Technology Data Exchange (ETDEWEB)

    1994-01-01

    this is an alternative evaluation document that records the evaluation process and justification for choosing the alternative recommended for the decontamination and decommissioning (D&D) of the 3506 and 3515 buildings at the Oak Ridge National Laboratory (ORNL). The alternatives for the D&D of the two buildings were: (1) no action (continued surveillance and maintenance), (2) decontamination for free release, (3) entombment in place, (4) partial dismantlement, and (5) complete dismantlement. Soil remediation is not included in any of the alternatives. The recommended alternative for the D&D of Building 3506 is partial dismantlement at an estimated cost of $936, 000 in escalated dollars. The cost estimate for complete dismantlement is $1,384,000. The recommended alternative for the D&D of Building 3515 is complete dismantlement at an estimated cost of $3,733,000 in escalated dollars. This alternative is recommended, because the soils below the foundation of the 3515 building are highly contaminated, and removing the foundation in the D&D project results in lower overall worker risk, costs, and improved post-D&D site conditions. A further recommendation is to revise these cost estimates after the conclusion of the ongoing characterization study. The results of the characterization of the two buildings is expected to change some of the assumptions and resolve some of the uncertainties in the development of these estimates.

    1998-01-01

    The Picture Exchange Communication System (PECS) was developed as a means to teach children with autism and related developmental disabilities a rapidly acquired, self-initiating, functional communication system. Its theoretical roots combine principles from applied behavior analysis and guidelines established within the field of alternative and augmentative communication. This approach has several potential advantages relative to imitation-based strategies (both vocal and gestural) and symbol selection strategies. The system begins with the exchange of simple icons but rapidly builds "sentence" structure. The system also emphasizes developing the request function prior to developing responding to simple questions and commenting. The development of requesting with a sentence structure also permits the rapid development of attributes more traditionally taught within a receptive mode. The relationship between the introduction of PECS and various other behavioral issues (i.e., social approach and behavior management) as well as its relationship to the codevelopment of speech are reviewed.

    2016-11-04

    The Medicare Access and CHIP Reauthorization Act of 2015 (MACRA) repeals the Medicare sustainable growth rate (SGR) methodology for updates to the physician fee schedule (PFS) and replaces it with a new approach to payment called the Quality Payment Program that rewards the delivery of high-quality patient care through two avenues: Advanced Alternative Payment Models (Advanced APMs) and the Merit-based Incentive Payment System (MIPS) for eligible clinicians or groups under the PFS. This final rule with comment period establishes incentives for participation in certain alternative payment models (APMs) and includes the criteria for use by the Physician-Focused Payment Model Technical Advisory Committee (PTAC) in making comments and recommendations on physician-focused payment models (PFPMs). Alternative Payment Models are payment approaches, developed in partnership with the clinician community, that provide added incentives to deliver high-quality and cost-efficient care. APMs can apply to a specific clinical condition, a care episode, or a population. This final rule with comment period also establishes the MIPS, a new program for certain Medicare-enrolled practitioners. MIPS will consolidate components of three existing programs, the Physician Quality Reporting System (PQRS), the Physician Value-based Payment Modifier (VM), and the Medicare Electronic Health Record (EHR) Incentive Program for Eligible Professionals (EPs), and will continue the focus on quality, cost, and use of certified EHR technology (CEHRT) in a cohesive program that avoids redundancies. In this final rule with comment period we have rebranded key terminology based on feedback from stakeholders, with the goal of selecting terms that will be more easily identified and understood by our stakeholders.

    powerhouse flows in the tailrace channel and resultant exchange in route to the next downstream dam. Currently, there exists a need to summarize the general finding from operational and structural TDG abatement programs conducted throughout the CRB and for the development of a generalized prediction model that pools data collected at multiple projects with similar structural attributes. A generalized TDG exchange model can be tuned to specific projects and coupled with water regulation models to allow the formulation of optimal daily water regulation schedules subject to water quality constraints for TDG supersaturation. A generalized TDG exchange model can also be applied to other hydropower dams that affect TDG pressures in tailraces and can be used to develop alternative operational and structural measures to minimize TDG generation. It is proposed to develop a methodology for predicting TDG levels downstream of hydropower facilities with similar structural properties as a function of a set of variables that affect TDG exchange; such as tailwater depth, spill discharge and pattern, project head, and entrainment of powerhouse releases. TDG data from hydropower facilities located throughout the northwest region of the United States will be used to identify relationships between TDG exchange and relevant dependent variables. Data analysis and regression techniques will be used to develop predictive TDG exchange expressions for various structural categories.

    Since 1970, solid waste with TRU or U-233 contamination in excess of 10 ..mu..Ci per kilogram of waste has been stored in a retrievable fashion at ORNL, such as in ss drums, concrete casks, and ss-lined wells. This report describes the results of a study performed to identify and evaluate alternatives for management of this waste and of the additional waste projected to be stored through 1995. The study was limited to consideration of the following basic strategies: Strategy 1: Leave waste in place as is; Strategy 2: Improve waste confinement; and Strategy 3: Retrieve waste and process for shipment to a Federal repository. Seven alternatives were identified and evaluated, one each for Strategies 1 and 2 and five for Strategy 3. Each alternative was evaluated from the standpoint of technical feasibility, cost, radiological risk and impact, regulatory factors and nonradiological environmental impact.

They are to: discuss programs that are driving the introduction of alternative fuels into fleet operations in urban areas around the country; define alternative fuels; quantify the present use and future projections on alternative fuel vehicles (AVFs) in the Chicago metropolitan statistical area; and discuss benefits of increased use of alternative fuels in urban areas. Factors which touch on these points include: present domestic dependence on petroleum for autos, with usage exceeding production; the large populations in urban areas which do not meet Clean Air Standards; recent legislative initiatives which give guidance and aid in the adoption of such strategies.

    Family strengthening has become a source of growing interest, research, and program design in the fields of prevention and treatment for problems of youth delinquency, school failure, alcohol, tobacco and other drug abuse (ATOD). Despite many studies that illustrate the positive outcomes of family strengthening programs and family-focused interventions, their use in communities has not advanced commensurate with their promise. This article offers a rationale for why programming efforts shou...

  13. Ideal Heat Exchange System

    2017-09-01

    The requirements with which a heat exchange system should comply in order that at certain values of the total contact surface and heat load the entropy production in it should be minimal have been determined. It has been shown that this system can serve as a standard for real systems of irreversible heat exchange. We have found the conditions for physical realizability of a heat exchange system in which heat exchange occurs by a law linear with respect to the temperature difference between contacting flows. Analogous conditions are given without deriving for the case of heat exchange by the Fourier law.

    We extend replica-exchange simulation in two ways and apply our approaches to biomolecules. The first generalization permits exchange simulation between models of differing resolution--i.e., between detailed and coarse-grained models. Such "resolution exchange" can be applied to molecular systems or spin systems. The second extension is to "pseudoexchange" simulations, which require little CPU usage for most levels of the exchange ladder and also substantially reduce the need for overlap between levels. Pseudoexchanges can be used in either replica or resolution exchange simulations. We perform efficient, converged simulations of a 50-atom peptide to illustrate the new approaches.

  18. Searching for an Appropriate Exchange Rate Regime

    Directory of Open Access Journals (Sweden)

    Yunjong Wang

    2001-06-01

    Full Text Available This paper attempts to survey current debates on the choice of exchange rate regime in emerging market economies. The issue of choosing an appropriate exchange rate regime is being actively discussed since the recent Asian crisis. As a lesson from the recent crises, one widely shared conclusion is that soft peg exchange rate regimes are extremely vulnerable in a world of volatile capital movements. Consequently, new orthodoxy based on the impossible trinity hypothesis favours two corner solutions ― greater flexibility or credible institutional assurance, like a currency board system or dollarization. Nevertheless, questions whether such corner solutions are adequate for developing countries are rising of late. "Fear of floating" is still conspicuous in many developing countries having adopted nominally a free-floating exchange rate regime. Developing countries are sensitive to exchange rate fluctuations because the cost of exchange rate volatility is greater than the benefit when compared to developed countries. Monitoring bands is a compromise solution, but it still needs further enhancement of estimation techniques for fundamental equilibrium exchange rates in order to make those estimation results more workable in practice. Other alternatives include the creation of soft peg of the G-3 currencies. Despite counterarguments, the stability of G-3 currencies could prove to be beneficial to emerging market economies.

  20. High heat flux single phase heat exchanger

    Science.gov (United States)

    Valenzuela, Javier A.; Izenson, Michael G.

    1990-01-01

    This paper presents the results obtained to date in a program to develop a high heat flux, single-phase heat exchanger for spacecraft thermal management. The intended application is a net generation interface heat exchanger to couple the crew module water thermal bus to the two-phase ammonia main thermal bus in the Space Station Freedom. The large size of the interface heat exchanger is dictated by the relatively poor water-side heat transfer characteristics. The objective of this program is to develop a single-phase heat transfer approach which can achieve heat fluxes and heat transfer coefficients comparable to those of the evaporation ammonia side. A new heat exchanger concept has been developed to meet these objecties. The main feature of this heat exchanger is that it can achieve very high heat fluxes with a pressure drop one to two orders of magnitude lower than those of previous microchannel or jet impingement high heat flux heat exchangers. This paper describes proof-of-concept experiments performed in air and water and presents analytical model of the heat exchanger.

    Full Text Available This article considers the use of Exchange-Traded Funds (ETFs for indexing the portfolios of pension funds in Brazil. A methodology is proposed to allow the portfolio managers to combine ETFs and the assets composing its benchmark. The methodology is based on a mathematical programming model, with the resulting problem solved by any global optimization algorithm. The results obtained for two ETFs – BOVA11 (indexed to the Ibovespa and BRAX11 (indexed to the IBrX-100 – are presented for illustrative purposes. All constraints imposed by the Brazilian regulatory environment have been incorporated in the studies presented. The methodology proved to be an interesting alternative to pension fund managers, with good results with respect to the control of tracking errors.

  14. Adaptively Compressed Exchange Operator

    CERN Document Server

    Lin, Lin

    2016-01-01

    The Fock exchange operator plays a central role in modern quantum chemistry. The large computational cost associated with the Fock exchange operator hinders Hartree-Fock calculations and Kohn-Sham density functional theory calculations with hybrid exchange-correlation functionals, even for systems consisting of hundreds of atoms. We develop the adaptively compressed exchange operator (ACE) formulation, which greatly reduces the computational cost associated with the Fock exchange operator without loss of accuracy. The ACE formulation does not depend on the size of the band gap, and thus can be applied to insulating, semiconducting as well as metallic systems. In an iterative framework for solving Hartree-Fock-like systems, the ACE formulation only requires moderate modification of the code, and can be potentially beneficial for all electronic structure software packages involving exchange calculations. Numerical results indicate that the ACE formulation can become advantageous even for small systems with tens...

    Objective To determine support of in-pharmacy HIV-testing among pharmacy staff and the individual-level characteristics associated with in-pharmacy HIV testing support. Design Descriptive, nonexperimental, cross-sectional study. Setting New York City (NYC) during January 2008 to March 2009. Intervention 131 pharmacies registered in the Expanded Syringe Access Program (ESAP) completed a survey. Participants 480 pharmacy staff, including pharmacists, owners/managers, and technicians/clerks. Main outcome measures Support of in-pharmacy HIV testing. Results Support of in-pharmacy HIV testing is high among pharmacy staff (79.4%). Pharmacy staff that supported in-pharmacy vaccinations were significantly more likely to support in-pharmacy HIV testing. Pharmacy staff that think that selling syringes to IDUs causes the community to be littered with dirty syringes were significantly less likely to support in-pharmacy HIV testing. Conclusion Support for in-pharmacy HIV testing is high among our sample of ESAP pharmacy staff actively involved in non-prescription syringe sales. These findings suggest that active ESAP pharmacy staff may be amenable to providing HIV counseling and testing to injection drug users and warrants further investigation. PMID:22825227

    In an effort to address concerns such as energy security, reliability, affordability, and other objectives, the Government of the Lao People's Democratic Republic (Lao PDR) is seeking to advance its expertise and experience in energy system analysis and planning to explore energy alternatives. Assessing the potential and alternatives for deploying energy technology options is often an early step - and, in most cases, an ongoing process - in planning for the development of the energy sector as a whole. Reliable and robust data are crucial to conducting these types of planning-related analyses in a transparent manner that builds confidence among power sector stakeholders and encourages investment in future energy project development and infrastructure opportunities. This report represents the first output of the Energy Alternatives Study for the Lao PDR (Energy Alternatives Study), a collaboration between Ministry of Energy and Mines and the United States Agency for International Development (USAID) under the auspices of the Smart Infrastructure for the Mekong (SIM) program. The Energy Alternatives Study includes five tasks that build upon each other to meet the goal of the project. The report summarizes the availability, quality, and accessibility of data that serve as key inputs to energy planning activities for the power sector. The purpose of this data assessment is two-fold: 1. To facilitate the informed use of existing data by highlighting applications for these data as they relate to priority energy planning analyses; and 2. To inform future investments in energy data collection and management by identifying significant data gaps and providing guidance on how to fill these gaps.

    2010-10-01

    The objective of this research is to develop tools to design and optimize heat exchangers (HE) and compact heat exchangers (CHE) for intermediate loop heat transport systems found in the very high temperature reator (VHTR) and other Generation IV designs by addressing heat transfer surface augmentation and conjugate modeling. To optimize heat exchanger, a fast running model must be created that will allow for multiple designs to be compared quickly. To model a heat exchanger, volume averaging theory, VAT, is used. VAT allows for the conservation of mass, momentum and energy to be solved for point by point in a 3 dimensional computer model of a heat exchanger. The end product of this project is a computer code that can predict an optimal configuration for a heat exchanger given only a few constraints (input fluids, size, cost, etc.). As VAT computer code can be used to model characteristics )pumping power, temperatures, and cost) of heat exchangers more quickly than traditional CFD or experiment, optimization of every geometric parameter simultaneously can be made. Using design of experiment, DOE and genetric algorithms, GE, to optimize the results of the computer code will improve heat exchanger disign.

  10. The simulation of the alternate turbopump development high pressure oxygen and fuel turbopumps for the space shuttle main engine using the Shaberth computer program

    Science.gov (United States)

    Mcdonald, Gary H.

    1988-01-01

    The Space Shuttle Main Engine (SSME) is basically comprised of a combustion chamber and nozzle, high and low pressure oxygen turbopumps and high and low pressure fuel turbopumps. In the current configuration, the high pressure fuel (HPTFP) and high pressure oxygen turbopumps (HPOTP) have experienced a history of ball bearing wear. The wear problem can be attributed to numerous factors including the hydrodynamic axial and radial loads caused by the flow of liquid oxygen and liquid hydrogen through the turbopump impellers and turbine. Also, friction effects between the rolling elements, races, and cage can create thermally induced bearing geometry changes. To alleviate some of the current configuration problems, an alternate turbopump development (ATD) was proposed. However, the ATD HPOTP and HPTFP are constrained to operate interchangeably with the current turbopumps, thus, the operation conditions must be similar. The ATD configuration features a major change in bearings used to support the integrated shaft, impeller, and turbine system. A single ball and single roller will replace the pump-end and turbine and duplex ball bearings. The Shaft-Bearing-Thermal (SHABERTH) computer code was used to model the ATD HPOTP and ATD HPFTP configurations. A two bearing model was used to simulate the HPOTP and HPFTP bearings and shaft geometry. From SHABERTH, a comparison of bearing reaction loads, frictional heat generation rates, and Hertz contact stresses will be attempted with analysis at the 109 percent and 65 percent power levels.

  11. Review of Robust Data Exchange Using Optical Nonlinearities

    Directory of Open Access Journals (Sweden)

    2012-01-01

    Full Text Available Data exchange, namely bidirectional information swapping, provides enhanced flexibility compared to the unidirectional information transfer. To fulfill the rapid development of high-speed large-capacity optical communications with emerging multiplexing/demultiplexing techniques and advanced modulation formats, a laudable goal would be to achieve data exchange in different degrees of freedom (wavelength, time, polarization, for different modulation formats (OOK, DPSK, DQPSK, pol-muxed, and at different granularities (entire data, groups of bits, tributary channels. Optical nonlinearities are potentially suitable candidates to enable data exchange in the wavelength, time, and polarization domains. In this paper, we will review our recent works towards robust data exchange by exploiting miscellaneous optical nonlinearities, including the use of cSFG/DFG in a PPLN waveguide for time- (groups of bits and channel-selective data exchange and tributary channel exchange between two WDM+OTDM signals, nondegenerate FWM in an HNLF for phase-transparent data exchange (DPSK, DQPSK, bidirectional degenerate FWM in an HNLF for multi-channel data exchange, and Kerr-induced nonlinear polarization rotation in an HNLF for tributary channel exchange of a pol-muxed DPSK OTDM signal. The demonstrated data exchanges in different degrees of freedom, for different modulation formats, and at different granularities, open the door for alternative approaches to achieve superior network performance.

    An anion exchange membrane and fuel cell incorporating the anion exchange membrane are detailed in which proazaphosphatrane and azaphosphatrane cations are covalently bonded to a sulfonated fluoropolymer support along with anionic counterions. A positive charge is dispersed in the aforementioned cations which are buried in the support to reduce the cation-anion interactions and increase the mobility of hydroxide ions, for example, across the membrane. The anion exchange membrane has the ability to operate at high temperatures and in highly alkaline environments with high conductivity and low resistance.

  14. Recommendation of a More Effective Alternative to the NASA Launch Services Program Mission Integration Reporting System (MIRS) and Implementation of Updates to the Mission Plan

    Dunn, Michael R.

    2014-01-01

    Over the course of my internship in the Flight Projects Office of NASA's Launch Services Program (LSP), I worked on two major projects, both of which dealt with updating current systems to make them more accurate and to allow them to operate more efficiently. The first project dealt with the Mission Integration Reporting System (MIRS), a web-accessible database application used to manage and provide mission status reporting for the LSP portfolio of awarded missions. MIRS had not gone through any major updates since its implementation in 2005, and it was my job to formulate a recommendation for the improvement of the system. The second project I worked on dealt with the Mission Plan, a document that contains an overview of the general life cycle that is followed by every LSP mission. My job on this project was to update the information currently in the mission plan and to add certain features in order to increase the accuracy and thoroughness of the document. The outcomes of these projects have implications in the orderly and efficient operation of the Flight Projects Office, and the process of Mission Management in the Launch Services Program as a whole.

    We report the use of auto-sampler programmable functions to co-inject analyte standard solution and matrix extract to assess ion enhancement and suppression (matrix effects) in LC-MS. This is effectively an automated post-extraction addition (APEA) procedure, emulating the manual post-extraction addition (PEA) approach widely adopted for assessment of matrix effects. To verify that APEA was comparable to the conventional PEA approach, matrix effects were determined using both methods for a selection of 31 illicit and pharmaceutical drugs in 10 different human urine extracts. Matrix effects measured using APEA were statistically indistinguishable from manual PEA methodology for 27 of the 31 drugs. Of the four drugs that showed significant differences using the two methods, three differed by less than 2 %, which is within the expected accuracy limits required for matrix effect determinations. The remaining analyte, trimeprazine, was found to degrade in the spiked PEA matrix extract, accounting for the difference between matrix effects measured by the PEA and APEA approaches. APEA enables a single matrix extract to be assessed at multiple analyte concentrations, resulting in a considerable reduction in sample preparation time. In addition, APEA can reduce the quantity of analyte-free sample matrix required for matrix effect assessment, which is an important consideration in certain analytical and bioanalytical fields. This work shows that APEA may be considered as an acceptable alternative to PEA for the assessment of matrix effects in LC-MS method validation and may be applicable to a variety of matrices such as environmental samples.

    To compare outcomes and costs for patients with orthogeriatric conditions in a home-based integrated care program versus conventional hospital-based care. Quasi-experimental longitudinal study. An acute care hospital, an intermediate care hospital, and the community of an urban area in the North of Barcelona, in Southern Europe. In a 2-year period, we recruited 367 older patients attended at an orthopedic/traumatology unit in an acute hospital for fractures and/or arthroplasty. Patients were referred to a hospital-at-home integrated care unit or to standard hospital-based postacute orthogeriatric unit, based on their social support and availability of the resource. We compared home-based care versus hospital-based care for Relative Functional Gain (gain/loss of function measured by the Barthel Index), mean direct costs, and potential savings in terms of reduction of stay in the acute care hospital. No differences were found in Relative Functional Gain, median (Q25-Q75) = 0.92 (0.64-1.09) in the home-based group versus 0.93 (0.59-1) in the hospital-based group, P =.333. Total health service direct cost [mean (standard deviation)] was significantly lower for patients receiving home-based care: €7120 (3381) versus €12,149 (6322), P home-based care [10.1 (7)] than in patients discharged to the postacute orthogeriatric hospital-based unit [15.3 (12) days, P home integrated care program was suitable for managing older patients with orthopedic conditions who have good social support for home care. It provided clinical care comparable to the hospital-based model, and it seems to enable earlier acute hospital discharge and lower direct costs.

    2017-06-01

    With the introduction of the Medicare Access and Children's Health Insurance Program Reauthorization Act, clinicians who are not eligible for an exemption must choose to participate in 1 of 2 new reimbursement models: the Merit-based Incentive Payment System or Alternative Payment Models (APMs). Although most dermatologists are expected to default into the Merit-based Incentive Payment System, some may have an interest in exploring APMs, which have associated financial incentives. However, for dermatologists interested in the APM pathway, there are currently no options other than joining a qualifying Accountable Care Organization, which make up only a small subset of Accountable Care Organizations overall. As a result, additional APMs relevant to dermatologists are needed to allow those interested in the APMs to explore this pathway. Fortunately, the Medicare Access and Children's Health Insurance Program Reauthorization Act establishes a process for new APMs to be approved and the creation of bundled payments for skin diseases may represent an opportunity to increase the number of APMs available to dermatologists. In this article, we will provide a detailed review of APMs under the Medicare Access and Children's Health Insurance Program Reauthorization Act and discuss the development and introduction of APMs as they pertain to dermatology.

    A heat exchanger having a plurality of heat exchanging aluminum fins with hydrophilic condensing surfaces which are stacked and clamped between two cold plates. The cold plates are aligned radially along a plane extending through the axis of a cylindrical duct and hold the stacked and clamped portions of the heat exchanging fins along the axis of the cylindrical duct. The fins extend outwardly from the clamped portions along approximately radial planes. The spacing between fins is symmetric about the cold plates, and are somewhat more closely spaced as the angle they make with the cold plates approaches 90.degree.. Passageways extend through the fins between vertex spaces which provide capillary storage and communicate with passageways formed in the stacked and clamped portions of the fins, which communicate with water drains connected to a pump externally to the duct. Water with no entrained air is drawn from the capillary spaces.

    2011-05-01

    Ion exchange phenomena involve the population of readily exchangeable ions, the subset of adsorbed solutes that balance the intrinsic surface charge and can be readily replaced by major background electrolyte ions (Sposito, 2008). These phenomena have occupied a central place in soil chemistry research since Way (1850) first showed that potassium uptake by soils resulted in the release of an equal quantity of moles of charge of calcium and magnesium. Ion exchange phenomena are now routinely modeled in studies of soil formation (White et al., 2005), soil reclamation (Kopittke et al., 2006), soil fertilitization (Agbenin and Yakubu, 2006), colloidal dispersion/flocculation (Charlet and Tournassat, 2005), the mechanics of argillaceous media (Gajo and Loret, 2007), aquitard pore water chemistry (Tournassat et al., 2008), and groundwater (Timms and Hendry, 2007; McNab et al., 2009) and contaminant hydrology (Chatterjee et al., 2008; van Oploo et al., 2008; Serrano et al., 2009).

    2017-11-01

    Phase-exchange thermoacoustic engines are reliable machines holding great promise in converting heat from low grade heat sources to mechanical or electrical power. In these engines the working fluid is a gas mixture containing one condensable component, decreasing the temperature difference required for ignition and steady state operation. Our experimental setup consists of a vertical acoustic resonator containing a mixture of air-water vapor. Water evaporates near the heat source, condenses at the heat sink and is drawn back down by gravity and capillary forces where it re-evaporates, sustaining a steady state closed thermodynamic cycle. We investigated the stability limit, namely the critical point at which temperature difference in the engine enables onset of self-excited oscillations, and the steady state of the engine. A simple theoretical model was derived, describing mechanisms of irreversible entropy generation and production of acoustic power in such engines. This model captures the essence in the differences between regular and phase-exchange thermoacoustic engines, and shows good agreement with experimental results of stability limit. Steady state results reveal not only a dramatic decrease in temperature difference, but also an increase in engine performances. The authors acknowledge the support from the Nancy and Stephen Grand Technion Energy Program (GTEP).

  6. Counterflow Regolith Heat Exchanger

    Zubrin, Robert; Jonscher, Peter

    2013-01-01

    A problem exists in reducing the total heating power required to extract oxygen from lunar regolith. All such processes require heating a great deal of soil, and the heat energy is wasted if it cannot be recycled from processed material back into new material. The counterflow regolith heat exchanger (CoRHE) is a device that transfers heat from hot regolith to cold regolith. The CoRHE is essentially a tube-in-tube heat exchanger with internal and external augers attached to the inner rotating tube to move the regolith. Hot regolith in the outer tube is moved in one direction by a right-hand - ed auger, and the cool regolith in the inner tube is moved in the opposite direction by a left-handed auger attached to the inside of the rotating tube. In this counterflow arrangement, a large fraction of the heat from the expended regolith is transferred to the new regolith. The spent regolith leaves the heat exchanger close to the temperature of the cold new regolith, and the new regolith is pre-heated close to the initial temperature of the spent regolith. Using the CoRHE can reduce the heating requirement of a lunar ISRU system by 80%, reducing the total power consumption by a factor of two. The unique feature of this system is that it allows for counterflow heat exchange to occur between solids, instead of liquids or gases, as is commonly done. In addition, in variants of this concept, the hydrogen reduction can be made to occur within the counterflow heat exchanger itself, enabling a simplified lunar ISRU (in situ resource utilization) system with excellent energy economy and continuous nonbatch mode operation.

    Cabraal, A.

    1997-12-01

    The author discusses efforts by the Asia Alternative Energy Unit (ASTAE) of the World Bank in supporting alternative energy source projects in Asia. Energy growth rates have been as high as 18% per year, with power capacity doubling each decade in the 1960`s, 70`s and 80`s. Much of this has come from fossil fuel projects coupled with major hydroelectric projects. One consequence is developing air pollution loads originating in Asia. ASTAE has been supporting pilot programs in applying alternative energy sources. The goal has been to mainstream renewable energy sources in World Bank operations, by working with managers from different countries to: include renewable energy in country assistance strategies and sectorial development plans; provide assistance to renewable energy initiatives; expand initiatives to new countries, sectors and technologies.

    2004-01-01

    A micro-scale regenerative heat exchanger has been designed, optimized and fabricated for use in a micro-Stirling device. Novel design and fabrication techniques enabled the minimization of axial heat conduction losses and pressure drop, while maximizing thermal regenerative performance. The fabricated prototype is comprised of ten separate assembled layers of alternating metal-dielectric composite. Each layer is offset to minimize conduction losses and maximize heat transfer by boundary layer disruption. A grating pattern of 100 micron square non-contiguous flow passages were formed with a nominal 20 micron wall thickness, and an overall assembled ten-layer thickness of 900 microns. Application of the micro heat exchanger is envisioned in the areas of micro-refrigerators/coolers, micropower devices, and micro-fluidic devices.

    Synopsis Given the severity of their illness and lack of effective disease modifying agents, it is not surprising that most patients with ALS consider trying complementary and alternative therapies. Some of the most commonly considered alternative therapies include special diets, nutritional supplements, cannabis, acupuncture, chelation and energy healing. This chapter reviews these in detail. We also describe 3 models by which physicians may frame discussions about alternative therapies: paternalism, autonomy and shared decision making. Finally, we review a program called ALSUntangled which using shared shared decision making to review alternative therapies for ALS. PMID:26515629

To provide insights into the clustering of the exchange rate time series, we investigate dynamic communities in the network. We show that there is a relationship between an exchange rate's functional role withi...

  16. Serial tempering without exchange.

    Science.gov (United States)

    Nymeyer, Hugh

    2010-09-21

    Serial tempering is a computational method that turns the temperature T (or more generally any independent λ parameter) into a dynamical variable. It is shown that, under conditions for which this variable is fast, serial tempering is equivalent to the umbrella sampling method with a single effective potential. This equivalence is demonstrated using both a small one-dimensional system and a small solvated peptide. The suggestion is then made to replace the serial tempering protocol with the equivalent umbrella sampling calculation. This approach, serial tempering without exchange (STeWiE), has the same performance as serial tempering in the limit that exchanges are frequent, is simpler to implement, and has fewer adjustable parameters than conventional serial tempering. The equivalence of serial tempering and STeWiE also provides a convenient route for estimating and optimizing the performance of serial tempering simulations and other generalized-ensemble methods.

  17. Lipid exchange by ultracentrifugation

    DEFF Research Database (Denmark)

    Drachmann, Nikolaj Düring; Olesen, Claus

    2014-01-01

    Lipids play an important role in maintaining P-type ATPase structure and function, and often they are crucial for ATPase activity. When the P-type ATPases are in the membrane, they are surrounded by a mix of different lipids species with varying aliphatic chain lengths and saturation......, and the complex interplay between the lipids and the P-type ATPases are still not well understood. We here describe a robust method to exchange the majority of the lipids surrounding the ATPase after solubilisation and/or purification with a target lipid of interest. The method is based on an ultracentrifugation...... step, where the protein sample is spun through a dense buffer containing large excess of the target lipid, which results in an approximately 80-85 % lipid exchange. The method is a very gently technique that maintains protein folding during the process, hence allowing further characterization...

    This study examined the rebounds in the exchange rate after foreign exchange intervention. When intervention is strongly effective, the exchange rate rebounds at next day. The effect of intervention is reduced slightly by the rebound after the intervention. The exchange rate might have been 67.12-77.47 yen to a US dollar without yen-selling/dollar-purchasing intervention of 74,691,100 million yen implemented by the Japanese government since 1991, in comparison to the actual exchange rate was 103.19 yen to the US dollar at the end of March 2014.

    Rao, Chetan S; Hartel, Richard W

    2006-01-01

    Scraped surface heat exchangers (SSHEs) are commonly used in the food, chemical, and pharmaceutical industries for heat transfer, crystallization, and other continuous processes. They are ideally suited for products that are viscous, sticky, that contain particulate matter, or that need some degree of crystallization. Since these characteristics describe a vast majority of processed foods, SSHEs are especially suited for pumpable food products. During operation, the product is brought in contact with a heat transfer surface that is rapidly and continuously scraped, thereby exposing the surface to the passage of untreated product. In addition to maintaining high and uniform heat exchange, the scraper blades also provide simultaneous mixing and agitation. Heat exchange for sticky and viscous foods such as heavy salad dressings, margarine, chocolate, peanut butter, fondant, ice cream, and shortenings is possible only by using SSHEs. High heat transfer coefficients are achieved because the boundary layer is continuously replaced by fresh material. Moreover, the product is in contact with the heating surface for only a few seconds and high temperature gradients can be used without the danger of causing undesirable reactions. SSHEs are versatile in the use of heat transfer medium and the various unit operations that can be carried out simultaneously. This article critically reviews the current understanding of the operations and applications of SSHEs.

  8. Timing Foreign Exchange Markets

    Directory of Open Access Journals (Sweden)

    Samuel W. Malone

    2016-03-01

    Full Text Available To improve short-horizon exchange rate forecasts, we employ foreign exchange market risk factors as fundamentals, and Bayesian treed Gaussian process (BTGP models to handle non-linear, time-varying relationships between these fundamentals and exchange rates. Forecasts from the BTGP model conditional on the carry and dollar factors dominate random walk forecasts on accuracy and economic criteria in the Meese-Rogoff setting. Superior market timing ability for large moves, more than directional accuracy, drives the BTGP’s success. We explain how, through a model averaging Monte Carlo scheme, the BTGP is able to simultaneously exploit smoothness and rough breaks in between-variable dynamics. Either feature in isolation is unable to consistently outperform benchmarks throughout the full span of time in our forecasting exercises. Trading strategies based on ex ante BTGP forecasts deliver the highest out-of-sample risk-adjusted returns for the median currency, as well as for both predictable, traded risk factors.

  9. Paste heat exchange

    Energy Technology Data Exchange (ETDEWEB)

    1943-07-30

    The subject of coal paste heat exchangers is discussed in this letter report from Gelsenberg A.G. to I.G. Farbenindustrie A.G. Gelsenberg had given little consideration to the heating of coal paste by means of regeneration (heat exchange) because of the lack of experience in paste regeneration with bituminous coal, especially at 700 atmospheres. At the I.G. Farben plant at Poelitz, paste regeneration was carried out so that low concentration coal paste was heated in the regenerator together with the process gas, and the remaining coal was fed into the cold pass of the preheater in a thicker paste. Later tests proved this process viable. Gelsenberg heated normal coal paste and the gas in heat exchangers with the goal of relieving the preheater. Good results were achieved without change in design. The coal paste was heated with process gas in the regenerator at up to 315 degrees with constant pressure difference, so that after three months no decrease in K-values and no deposition or thickening was observed. Through the omission of paste gas, the pressure difference of the system became more constant and did not rise above the former level. The temperature also was more controllable, the chamber smoother running. Principal thermal data are given in a table. 1 table, 1 graph.

    Phillips, Colin T; Tamez, Hector; Tu, Thomas M; Yeh, Robert W; Pinto, Duane S

    2017-07-01

    Patients with an indwelling Impella may require escalation of hemodynamic support or exchange to another circulatory assistance platform. As such, preservation of vascular access is preferable in cases where anticoagulation cannot be discontinued or to facilitate exchange to an alternative catheter or closure device. Challenges exist in avoiding bleeding and loss of wire access in these situations. We describe a single-access "Trojan Horse" technique that minimizes bleeding while maintaining arterial access for rapid exchange of this percutaneous ventricular assist device.
