    2010-02-01

    One of the key challenges for the advancement of nursing globally is the development of doctorally prepared educators and leaders in a context where there is a shortage of provision of doctoral nursing programmes. For the short term future, many nurses wishing to undertake a doctorate will need to complete this education in the USA, the UK or Australia. Very little is known however about the nature of their learning experiences in these countries. This paper presents a literature review on the international doctoral student experience, with specific reference to nursing. A thorough review of the literature from 1990 to 2009 was undertaken which yielded only three empirical studies related to nursing. The review was then expanded to include subjects other than nursing which yielded 16 studies in total. This paper presents key themes that appear to be generic to international doctoral students, and draws out specific implications for nursing. The review found that international doctoral students' learning experiences were strongly influenced by the extent to which they could engage with three key elements of doctoral programmes: The first months represented a critical time of transition and most international students seemed to want and expect considerable support and structured in-put during this period. Most studies concluded that there was a need for greater institutional support and supervisor training. The three nursing-specific papers were entirely consistent with these themes. The existing evidence is extremely heterogeneous and of variable methodological quality. In order to ensure that doctoral nursing students are getting a high quality and appropriate PhD experience, there is a need for more research specifically with this group. There is also a need to investigate the different stages of the doctoral process in nursing, including, for example, writing up and examination processes and post-doctoral career outcomes.

    This report summarizes the recently completed Phase I of the Project for Fracture Analysis of Large-Scale International Reference Experiments (Project FALSIRE). Project FALSIRE was created by the Fracture Assessment Group (FAG) of Principal Working Group No. 3 (PWG/3) of the Organization for Economic Cooperation and Development (OECD)/Nuclear Energy Agency`s (NEA`s) Committee on the Safety of Nuclear Installations (CSNI). Motivation for the project was derived from recognition by the CSNI-PWG/3 that inconsistencies were being revealed in predictive capabilities of a variety of fracture assessment methods, especially in ductile fracture applications. As a consequence, the CSNI/FAG was formed to evaluate fracture prediction capabilities currently used in safety assessments of nuclear components. Members are from laboratories and research organizations in Western Europe, Japan, and the United States of America (USA). On behalf of the CSNI/FAG, the US Nuclear Regulatory Commission`s (NRC`s) Heavy-Section Steel Technology (HSST) Program at the Oak Ridge National Laboratory (ORNL) and the Gesellschaft fuer Anlagen--und Reaktorsicherheit (GRS), Koeln, Federal Republic of Germany (FRG) had responsibility for organization arrangements related to Project FALSIRE.

    A summary of Phase II of the Project for Fracture Analysis of Large-Scale International Reference Experiments (FALSIRE) is presented. A FALSIRE II Workshop focused on analyses of reference fracture experiments. More than 30 participants representing 22 organizations from 12 countries took part in the workshop. Final results for 45 analyses of the reference experiments were received from the participating analysts. For each experiment, analysis results provided estimates of variables that include temperature, crack-mouth-opening displacement, stress, strain, and applied K and J values. The data were sent electronically to the Organizing Committee, who assembled the results into a comparative data base using a special-purpose computer program. A comparative assessment and discussion of the analysis results are presented in the report. Generally, structural responses of the test specimens were predicted with tolerable scatter bands.

    A summary of Phase II of the Project for FALSIRE is presented. FALSIRE was created by the Fracture Assessment Group (FAG) of the OECD/NEA`s Committee on the Safety of Nuclear Installations (CNSI) Principal Working Group No. 3. FALSIRE I in 1988 assessed fracture methods through interpretive analyses of 6 large-scale fracture experiments in reactor pressure vessel (RPV) steels under pressurized- thermal-shock (PTS) loading. In FALSIRE II, experiments examined cleavage fracture in RPV steels for a wide range of materials, crack geometries, and constraint and loading conditions. The cracks were relatively shallow, in the transition temperature region. Included were cracks showing either unstable extension or two stages of extensions under transient thermal and mechanical loads. Crack initiation was also investigated in connection with clad surfaces and with biaxial load. Within FALSIRE II, comparative assessments were performed for 7 reference fracture experiments based on 45 analyses received from 22 organizations representing 12 countries. Temperature distributions in thermal shock loaded samples were approximated with high accuracy and small scatter bands. Structural response was predicted reasonably well; discrepancies could usually be traced to the assumed material models and approximated material properties. Almost all participants elected to use the finite element method.

    The six experiments used in Project FALSIRE (performed in the Federal Republic of Germany, Japan, the United Kingdom, and the U.S.A.) were designed to examine various aspects of crack growth in reactor pressure vessel (RPV) steels under pressurized-thermal-shock (PTS) loading conditions. The CSNI/FAG established a common format for comprehensive statements of these experiments, including supporting information and available analysis results. For each experiment, analysis results provided estimates of variables such as crack growth, crack-mouth-opening displacement, temperature, stress, strain, and applied J and K values. A comparative assessment and discussion of the analysis results are presented; also, the current status of the entire results data base is summarized. Generally, these results highlight the importance of adequately modeling structural behavior of specimens before performing fracture mechanics evaluations. Applications of the various fracture methodologies were found to be partially successful in some cases but not in others. Based on these assessments, some conclusions concerning predictive capabilities of selected ductile fracture methodologies, as applied to RPVs subjected to PTS loading are given. (orig.)

  14. Optimized slice-selective 1H NMR experiments combined with highly accurate quantitative 13C NMR using an internal reference method

    Isotope ratio monitoring by 13C NMR spectrometry (irm-13C NMR) provides the complete 13C intramolecular position-specific composition at natural abundance. It represents a powerful tool to track the (bio)chemical pathway which has led to the synthesis of targeted molecules, since it allows Position-specific Isotope Analysis (PSIA). Due to the very small composition range (which represents the range of variation of the isotopic composition of a given nuclei) of 13C natural abundance values (50‰), irm-13C NMR requires a 1‰ accuracy and thus highly quantitative analysis by 13C NMR. Until now, the conventional strategy to determine the position-specific abundance xi relies on the combination of irm-MS (isotopic ratio monitoring Mass Spectrometry) and 13C quantitative NMR. However this approach presents a serious drawback since it relies on two different techniques and requires to measure separately the signal of all the carbons of the analyzed compound, which is not always possible. To circumvent this constraint, we recently proposed a new methodology to perform 13C isotopic analysis using an internal reference method and relying on NMR only. The method combines a highly quantitative 1H NMR pulse sequence (named DWET) with a 13C isotopic NMR measurement. However, the recently published DWET sequence is unsuited for samples with short T1, which forms a serious limitation for irm-13C NMR experiments where a relaxing agent is added. In this context, we suggest two variants of the DWET called Multi-WET and Profiled-WET, developed and optimized to reach the same accuracy of 1‰ with a better immunity towards T1 variations. Their performance is evaluated on the determination of the 13C isotopic profile of vanillin. Both pulse sequences show a 1‰ accuracy with an increased robustness to pulse miscalibrations compared to the initial DWET method. This constitutes a major advance in the context of irm-13C NMR since it is now possible to perform isotopic analysis with high

    The pathway from adverse early experience to adulthood for internationally adopted children is complex in identifying key influences, impacts, and outcomes. This review arose from the authors' involvement in the British Chinese Adoption Study, a recent outcomes study that explored the links between early orphanage care, adoptive experiences, and midadulthood. It differs from previous reviews in focusing on a greater length of time since adoption. Both quantitative and qualitative studies were included to allow for examination of a fuller range of adult-related outcomes rather than mental health scores alone. The sampling, methods, and results of reviewed articles are summarised and a critical commentary is provided. Despite methodological differences and identified strengths and weaknesses, conclusions are drawn on the basis of the evidence available. Special attention is paid to the interpretation of negative outcomes. Findings identify areas that should be explored further in order to gain a fuller understanding of midlife outcomes of people who experienced a poor start in life followed by international adoption. Such studies help in refining lifespan developmental theories.

    The International Linear Collider will give physicists a new cosmic doorway to explore energy regimes beyond the reach of today's accelerators. A proposed electron-positron collider, the ILC will complement the Large Hadron Collider, a proton-proton collider at the European Center for Nuclear Research (CERN) in Geneva, Switzerland, together unlocking some of the deepest mysteries in the universe. With LHC discoveries pointing the way, the ILC -- a true precision machine -- will provide the missing pieces of the puzzle. Consisting of two linear accelerators that face each other, the ILC will hurl some 10 billion electrons and their anti-particles, positrons, toward each other at nearly the speed of light. Superconducting accelerator cavities operating at temperatures near absolute zero give the particles more and more energy until they smash in a blazing crossfire at the centre of the machine. Stretching approximately 35 kilometres in length, the beams collide 14,000 times every second at extremely high energies -- 500 billion-electron-volts (GeV). Each spectacular collision creates an array of new particles that could answer some of the most fundamental questions of all time. The current baseline design allows for an upgrade to a 50-kilometre, 1 trillion-electron-volt (TeV) machine during the second stage of the project. This reference design provides the first detailed technical snapshot of the proposed future electron-positron collider, defining in detail the technical parameters and components that make up each section of the 31-kilometer long accelerator. The report will guide the development of the worldwide R and D program, motivate international industrial studies and serve as the basis for the final engineering design needed to make an official project proposal later this decade

    2015-12-01

    The International Reference Ionosphere (IRI) project was started in 1970 when the Committee on Space Research (COSPAR) and the International Union of Radio Science (URSI) joined forces to establish an internationally accepted reference model for the ionosphere. COSPAR needed such a specification for the evaluation of environmental effects on spacecraft and experiments in space, and URSI for radiowave propagation studies and applications. Because of this operational needs both unions requested that IRI be based primarily on data using all available and reliable data sources from space and ground. Similar activities had been started for the Atmosphere with the COSPAR International Reference Atmosphere (CIRA) model and for the Earth's magnetic field with the International Geomagnetic Reference Field (IGRF) model of the International Association of Geomagnetism and Aeronomy (IAGA). This presentation will give a brief overview over the IRI project and the progress made since its inception. An important milestone was reached early last year when IRI was voted to become the ISO standard for the ionosphere; the International Standardization Organization (ISO) is in charge of establishing and publishing international standards. This talk will discuss the most recent status of IRI activities including the development of a Real-Time IRI and the IRI 2015 Workshop, the first COSPAR Capacity Building Workshop on a Space Weather topic, that will be held in Bangkok from November 2 to 13. The IRI model is heavily used for a wide range of applications in science, engineering and education. We will discuss some of the more important ones of these applications and present measures of success that underline the superior performance of the model and the wide acceptance in the science community and science-interested public.

    2014-02-01

    Full Text Available The International Reference Ionosphere (IRI project was established jointly by the Committee on Space Research (COSPAR and the International Union of Radio Science (URSI in the late sixties with the goal to develop an international standard for the specification of plasma parameters in the Earth’s ionosphere. COSPAR needed such a specification for the evaluation of environmental effects on spacecraft and experiments in space, and URSI for radiowave propagation studies and applications. At the request of COSPAR and URSI, IRI was developed as a data-based model to avoid the uncertainty of theory-based models which are only as good as the evolving theoretical understanding. Being based on most of the available and reliable observations of the ionospheric plasma from the ground and from space, IRI describes monthly averages of electron density, electron temperature, ion temperature, ion composition, and several additional parameters in the altitude range from 60 km to 2000 km. A working group of about 50 international ionospheric experts is in charge of developing and improving the IRI model. Over time as new data became available and new modeling techniques emerged, steadily improved editions of the IRI model have been published. This paper gives a brief history of the IRI project and describes the latest version of the model, IRI-2012. It also briefly discusses efforts to develop a real-time IRI model.

    Full Text Available In the internal dose evaluation, the specific absorbed fraction (SAF and S-value are calculated from the reference phantom based on Caucasian data. The differences in height and weight between Caucasian and Asian may lead to inaccurate dose estimation. In this study, we developed the Taiwanese reference phantoms. 40 volunteers were recruited. Magnetic resonance images (MRI were obtained, and the contours of 15 organs were drawn. The Taiwanese reference man (TRM and Taiwanese reference woman (TRW were constructed. For the SAF calculation, the differences in the self-absorption SAF (self-SAF between the TRM, TRW, and Oak Ridge National Laboratory (ORNL adult phantom were less than 10% when the difference in organ mass was less than 20%. The average SAF from liver to pancreas of TRM was 38% larger than that of the ORNL adult phantom, and the result of TRW was 2.02 times higher than that of the ORNL adult phantom. For the S-value calculation, the ratios of TRW and ORNL adult phantom ranged from 0.91 to 1.57, and the ratios of TRM and ORNL adult phantom ranged from 1.04 to 2.29. The SAF and S-value results were dominantly affected by the height, weight, organ mass, and geometric relationship between organs. By using the TRM and TRW, the accuracy of internal dose evaluation can be increased for radiation protection and nuclear medicine.

  8. Vertical datum unification for the International Height Reference System (IHRS)

    Science.gov (United States)

    Sánchez, Laura; Sideris, Michael G.

    2017-05-01

    The International Association of Geodesy released in July 2015 a resolution for the definition and realisation of an International Height Reference System (IHRS). According to this resolution, the IHRS coordinates are potential differences referring to the equipotential surface of the Earth's gravity field realised by the conventional value W0 = 62 636 853.4 m2s-2. A main component of the IHRS realisation is the integration of the existing height systems into the global one; that is existing vertical coordinates should be referred to one and the same reference level realised by the conventional W0. This procedure is known as vertical datum unification and its main result are the vertical datum parameters, that is the potential differences between the local and the global reference levels. In this paper, we rigorously derive the observation equations for the vertical datum unification in terms of potential quantities based on the geodetic boundary value problem (GBVP) approach. Those observation equations are then empirically evaluated for the vertical datum unification of the North American and South American height systems. In the first case, simulations performed in North America provide numerical estimates about the impact of omission errors and direct and indirect effects on the vertical datum parameters. In the second case, a combination of local geopotential numbers, ITRF coordinates, satellite altimetry observations, tide gauge registrations and high-resolution gravity field models is performed to estimate the level differences between the South American height systems and the global level W0. Results show that indirect effects vanish when a satellite-only gravity field model with a degree higher than n ≥ 180 is used for the solution of the GBVP. However, the component derived from satellite-only global gravity models has to be refined with terrestrial gravity data to minimise the omission error and its effect on the vertical datum parameter estimation

    The international reference ionosphere (lRI) is the internationally recommended empirical model for the specification of ionospheric parameters supported by the Committee on Space Research (COSPAR) and the International Union of Radio Science (URSI) and recognized by the International Standardization Organization (ISO). IRI is being continually improved by a team of international experts as new data become available and better models are being developed. This issue chronicles the latest phase of model updates as reported during two IRI-related meetings. The first was a special session during the Scientific Assembly of the Committee of Space Research (COSPAR) in Montreal, Canada in July 2008 and the second was an IRI Task Force Activity at the US Air Force Academy in Colorado Springs in May 2009. This work led to several improvements and additions of the model which will be included in the next version, IRI-201O. The issue is divided into three sections focusing on the improvements made in the topside ionosphere, the F-peak, and the lower ionosphere, respectively. This issue would not have been possible without the reviewing efforts of many individuals. Each paper was reviewed by two referees. We thankfully acknowledge the contribution to this issue made by the following reviewers: Jacob Adeniyi, David Altadill, Eduardo Araujo, Feza Arikan, Dieter Bilitza, Jilijana Cander, Bela Fejer, Tamara Gulyaeva, Manuel Hermindez-Pajares, Ivan Kutiev, John MacDougal, Leo McNamara, Bruno Nava, Olivier Obrou, Elijah Oyeyemi, Vadym Paznukhov, Bodo Reinisch, John Retterer, Phil Richards, Gary Sales, J.H.

    This paper addresses two questions through a study of 180 SMEs located in contrasting industry and home country contexts. First, which business models for international markets prevail among SMEs and do they configure into different types? Second, which factors predict the international business...... models that SMEs follow? Three distinct international business models (traditional market-adaptive, technology exploiter, and ambidextrous explorer) are found among the SMEs studied. The likelihood of SMEs adopting one business model rather than another is to a high degree predictable with reference...... to a small set of factors: industry, level of home economy development, and decision-maker international experience....

    A program for decommissioning eight nuclear facilities has been underway by the Atomics International (AI) Division of Rockwell International during the past five years. The facilities are located at the Rockwell Santa Susana Field Laboratory, approximately 30 miles from the center of Los Angeles. The facilities served experimental and development programs for space nuclear power, liquid metal technology, and commercial power generation. The land involved is under lease to the Federal government and may revert to private ownership. The programs conducted in these facilities were terminated in the 1960s, and the facilities were placed in a layaway status. They were designated as being surplus to programmatic needs in the early 1970s, and decommissioning project authorization was received from the government in 1974

    1995-01-01

    An international survey was conducted to get the views of 147 professionals in the field on the definition of dietary fiber. The survey also solicited opinions on analytical methods for nutrition labeling, quality control, and nutrition research. The survey finds that dietary fiber is generally defined as polysaccharides and lignin that are not hydrolyzed by human alimentary enzymes. Support is strong for expansion of the definition to include oligosaccharides that are resistant to hydrolysis by human alimentary enzymes. Among techniques for nutrition labeling and quality control, enzymatic-gravimetric methods get the highest support. For nutrition research, more detailed methods such as gas-liquid chromatography and liquid chromatography were considered more appropriate. Respondents support labeling of total, soluble, and insoluble dietary fiber or total dietary fiber alone as sufficient for nutrition labeling of food packages. However, for nutrition research, detailed analytical methods, improvements in accuracy (i.e., closer simulation of in vitro techniques to conditions of human gastrointestinal tract), and improvements in precision and simplicity are suggested. Less than 20% of the participants use reference materials for dietary fiber analysis.

    To render a diagnosis pediatricians rely upon reference standards for bone mineral density or bone mineral content, which are based on cross-sectional data from a relatively small sample of children. These standards are unable to adequately represent growth in a diverse pediatric population. Thus, the goal of this study was to develop sex and site specific standards for BMC using longitudinal data collected from four international sites in Canada and the United States. Data from four studies were combined; Saskatchewan Paediatric Bone Mineral Accrual Study (n=251), UBC Healthy Bones Study (n=382); Penn State Young Women’s Health Study (n=112) and Stanford’s Bone Mineral Accretion study (n=423). Males and females (8 to 25 years) were measured for whole body (WB), total proximal femur (PF), femoral neck (FN) and lumbar spine (LS) BMC (g). Data were analyzed using random effects models. Bland-Altman was used to investigate agreement in predicted and actual data. Age, height, weight and ethnicity independently predicted BMC accrual across sites (P accounting for age, size, sex and ethnicity. In conclusion, when interpreting BMC in paediatrics we recommend standards that are sex, age, size and ethnic specific. PMID:19854308

    To identify reasons for inclusion of international practice experiences in pharmacy curricula and to understand the related structure, benefits, and challenges related to the programs. A convenience sample of 20 colleges and schools of pharmacy in the United States with international pharmacy education programs was used. Telephone interviews were conducted by 2 study investigators. University values and strategic planning were among key driving forces in the development of programs. Global awareness and cultural competency requirements added impetus to program development. Participants' advice for creating an international practice experience program included an emphasis on the value of working with university health professions programs and established travel programs. Despite challenges, colleges and schools of pharmacy value the importance of international pharmacy education for pharmacy students as it increases global awareness of health needs and cultural competencies.

  18. Universal Reference RNA as a standard for microarray experiments

    2004-03-01

    Full Text Available Abstract Background Obtaining reliable and reproducible two-color microarray gene expression data is critically important for understanding the biological significance of perturbations made on a cellular system. Microarray design, RNA preparation and labeling, hybridization conditions and data acquisition and analysis are variables difficult to simultaneously control. A useful tool for monitoring and controlling intra- and inter-experimental variation is Universal Reference RNA (URR, developed with the goal of providing hybridization signal at each microarray probe location (spot. Measuring signal at each spot as the ratio of experimental RNA to reference RNA targets, rather than relying on absolute signal intensity, decreases variability by normalizing signal output in any two-color hybridization experiment. Results Human, mouse and rat URR (UHRR, UMRR and URRR, respectively were prepared from pools of RNA derived from individual cell lines representing different tissues. A variety of microarrays were used to determine percentage of spots hybridizing with URR and producing signal above a user defined threshold (microarray coverage. Microarray coverage was consistently greater than 80% for all arrays tested. We confirmed that individual cell lines contribute their own unique set of genes to URR, arguing for a pool of RNA from several cell lines as a better configuration for URR as opposed to a single cell line source for URR. Microarray coverage comparing two separately prepared batches each of UHRR, UMRR and URRR were highly correlated (Pearson's correlation coefficients of 0.97. Conclusion Results of this study demonstrate that large quantities of pooled RNA from individual cell lines are reproducibly prepared and possess diverse gene representation. This type of reference provides a standard for reducing variation in microarray experiments and allows more reliable comparison of gene expression data within and between experiments and

    Little is known about the veterinary referral process and factors that contribute to positive outcomes. To investigate equine referring veterinarians' (rDVMs') satisfaction with their most recent referral experience and compare rDVM and specialist perspectives. 187 rDVMs and 92 specialists (referral care providers). Cross-sectional observational study. An online survey was administered to both rDVMs and specialists. Referring veterinarian satisfaction with their most recent referral experience was evaluated. Both rDVMs and specialists were asked to identify factors influencing a rDVM's decision where to refer, and the top 3 factors they perceive are barriers to referral care. Median rDVM satisfaction with their most recent referral care experience was 80 of 100 (mean, 75; range, 8-100). Referring veterinarians provided the lowest satisfaction score for the item asking about "The competition the referral hospital poses to your practice" (mean, 56.96; median, 62; range, 0-100). The top factor rDVMs identified as influencing their decision where to refer was "quality of care," whereas specialists identified "quality of communication and updates from the clinician." Referring veterinarians' top barrier to referral care was "high cost of referral care," and for specialists was "poor service provided to the client by the referral hospital." Referring veterinarians generally were satisfied with referral care, but areas exist where rDVMs and specialists differ in what they view as important to the referral process. Exploring opportunities to overcome these differences is likely to support high quality care. © 2018 The Authors.

  1. Experience with mechanical segmentation of reactor internals

    International Nuclear Information System (INIS)

    Carlson, R.; Hedin, G.

    2003-01-01

    Operating experience from BWE:s world-wide has shown that many plants experience initial cracking of the reactor internals after approximately 20 to 25 years of service life. This ''mid-life crisis'', considering a plant design life of 40 years, is now being addressed by many utilities. Successful resolution of these issues should give many more years of trouble-free operation. Replacement of reactor internals could be, in many cases, the most favourable option to achieve this. The proactive strategy of many utilities to replace internals in a planned way is a market-driven effort to minimize the overall costs for power generation, including time spent for handling contingencies and unplanned outages. Based on technical analyses, knowledge about component market prices and in-house costs, a cost-effective, optimized strategy for inspection, mitigation and replacements can be implemented. Also decommissioning of nuclear plants has become a reality for many utilities as numerous plants worldwide are closed due to age and/or other reasons. These facts address a need for safe, fast and cost-effective methods for segmentation of internals. Westinghouse has over the last years developed methods for segmentation of internals and has also carried out successful segmentation projects. Our experience from the segmentation business for Nordic BWR:s is that the most important parameters to consider when choosing a method and equipment for a segmentation project are: - Safety, - Cost-effectiveness, - Cleanliness, - Reliability.

    candidates to serve as a marker price in the international trade of gas. The objective of this paper is to examine some fundamental properties of the HH and NBP prices and assess which of them has the biggest potential to become an international price reference. Our main conclusions are: According to the relatively huge volume of gas traded on the US spot market, compared with the UK and according to the experience accumulated by the New York Mercantile Exchange (NYMEX) in gas trading, the HH price has a bigger potential than the NBP to become an international price reference, particularly because the UK market is supposed to import more and more gas indexed to oil in the coming years. However, on the price fluctuation side, the NBP spot price seems to fluctuate more normally than the HH price in the short term, which can give a certain advantage to NBP prices. We cannot exclude the fact that in the coming years we will have two or even more reference prices in the Atlantic Basin: the NBP, the HH and also reference prices at other regional hubs. (author)

    2005-09-01

    To evaluate if using an international growth reference versus a national growth reference leads to differences in the prevalences of low weight-for-height (wasting) and low height-for-age (stunting) in a sample of children 8 to 14 years old. A cross-sectional study was carried out with a sample of 1,470 school-children (both boys and girls) in the city of La Plata, in the province of Buenos Aires, Argentina. Based on the data on weight and height, Z-scores were calculated with regard to the reference values from the United States of America's first and second National Health and Nutrition Examination Survey (NHANES I and NHANES II), and the reference values for Argentina from the Argentine Pediatric Society. The prevalences of wasting and stunting were calculated, using as the cutoff point two standard deviations below the median of the reference. The prevalences were compared using the chi-squared test with Yates' correction, and odds ratios (ORs) and 95% confidence intervals (95% CIs) were calculated. The international reference was positively associated with a higher prevalence of stunting in the entire sample (OR = 5.12; 95% CI: 3.27 to 8.05), in the boys (OR = 4.36; 95% CI: 2.43 to 7.93), and in the girls (OR = 6.32; 95% CI: 3.10 to 13.27). The prevalence of wasting was similar with both references. The distribution of height-for-age was skewed to the left with respect to the international reference and to the right with respect to the Argentine reference, while the distribution of weight-for-height overlapped both references. The differences in the prevalences of stunting calculated according to the two references that were used indicate a different nutritional status for the population studied. The increase in the height of the children with respect to the Argentine reference points to the presence of a positive secular trend, and the increase can explain part of the differences in the prevalence of stunting.

    Orbital sensors to monitor global climate change during the next decade require low-drift rates for onboard thermometry, which is currently unattainable without on-orbit recalibration. Phase-change materials (PCMs), such as those that make up the ITS-90 standard, are seen as the most reliable references on the ground and could be good candidates for orbital recalibration. Space Dynamics Lab (SDL) has been developing miniaturized phase-change references capable of deployment on an orbital blackbody for nearly a decade. Improvement of orbital temperature measurements for long duration earth observing and remote sensing. To determine whether and how microgravity will affect the phase transitions, SDL conducted experiments with ITS-90 standard material (gallium, Ga) on the International Space Station (ISS) and compared the phase-change temperature with earth-based measurements. The miniature on-orbit thermal reference (MOTR) experiment launched to the ISS in November 2013 on Soyuz TMA-11M with the Expedition 38 crew and returned to Kazakhstan in March 2014 on the Soyuz TMA-10 spacecraft. MOTR tested melts and freezes of Ga using repeated 6-h cycles. Melt cycles obtained on the ground before and after launch were compared with those obtained on the ISS. To within a few mK uncertainty, no significant difference between the melt temperature of Ga at 1 g and in microgravity was observed.

    Various computational tools are currently available that facilitate patient organ dosimetry in diagnostic nuclear medicine, yet they are typically restricted to reporting organ doses to ICRP-defined reference phantoms. The present study, while remaining computational phantom based, provides straightforward tools to adjust reference phantom organ dose for both internal photon and electron sources. A wide variety of monoenergetic specific absorbed fractions (SAFs) were computed using radiation transport simulations for tissue spheres of varying size and separation distance. Scaling methods were then constructed for both photon and electron self-dose and cross-dose, with data validation provided from patient-specific voxel phantom simulations, as well via comparison to the scaling methodology given in MIRD Pamphlet No. 11. Photon and electron self-dose was found to be dependent on both radiation energy and sphere size. Photon cross-dose was found to be mostly independent of sphere size. Electron cross-dose was found to be dependent on sphere size when the spheres were in close proximity, owing to differences in electron range. The validation studies showed that this dataset was more effective than the MIRD 11 method at predicting patient-specific photon doses for at both high and low energies, but gave similar results at photon energies between 100 keV and 1 MeV. The MIRD 11 method for electron self-dose scaling was accurate for lower energies but began to break down at higher energies. The photon cross-dose scaling methodology developed in this study showed gains in accuracy of up to 9% for actual patient studies, and the electron cross-dose scaling methodology showed gains in accuracy up to 9% as well when only the bremsstrahlung component of the cross-dose was scaled. These dose scaling methods are readily available for incorporation into internal dosimetry software for diagnostic phantom-based organ dosimetry. © 2018 Institute of Physics and Engineering in

    Full Text Available The experience of organizing school nutrition in Europe and usais analyzed. It is noted that long term programs aimed at optimizing schoolchildren nutrition have a beneficial effect on the children's health, culture of their nutrition and quality of life. The importance of carrying out similar programs in Russia is beyond any doubt: according to population research, the basic principles of good nutrition are often not observed, and school breakfasts and lunches do not correspond to the age physiological needs of children and teenagers for nutrient materials and energy. In this situation, the available experience of using vitaminbenriched products as well as vitamin and mineral complexes in children will permit to quickly resolve the existing problems of the improper, and sometimes, insufficient, nutrition.Key words: school nutrition, organization, international experience.

    International adoption research has been called a natural experiment by many child development researchers. How do studies of severe early deprivation inform us about risk factors experienced by many of these children and their impact on developmental outcomes? Three longitudinal studies conducted by British and American researchers in the 1990s are reviewed. Each year, over 20,000 children are adopted from overseas, and a significant number are now entering adolescence; the impact of their prenatal risk factors, early institutionalization, and ameliorative postadoptive environments is also reviewed. The feasibility of generalizing findings to other children in foster care is also addressed.

    To assess the prevalence of child underweight, overweight, and obesity in a Malaysian population according to 3 international references because classification of anthropometric status may differ according to the reference used to express body mass index (BMI). We assessed data from 6414 children aged 6-18 years, collected by the South East Asia Community Observatory. Child underweight, overweight, and obesity were expressed according to 3 internationally used BMI references: World Health Organization 2007, International Obesity Task Force 2012, and Centers for Disease Control and Prevention 2000. We assessed agreement in classification of anthropometric status among the references using Cohen's kappa statistic and estimated underweight, overweight, and obesity prevalence according to each reference using mixed effects Poisson regression. There was poor to moderate agreement between references when classifying underweight, but generally good agreement when classifying overweight and obesity. Underweight, overweight, and obesity prevalence estimates generated using the 3 references were notably inconsistent. Overweight and obesity prevalence estimates were higher using the World Health Organization reference vs the other 2, and underweight prevalence was up to 8.5% higher and obesity prevalence was about 4% lower when using the International Obesity Task Force reference. The choice of reference to express BMI may influence conclusions about child anthropometric status and malnutrition prevalence. This has implications regarding strategies for clinical management and public health interventions. Copyright © 2017 The Authors. Published by Elsevier Inc. All rights reserved.

    Studying, understanding and modelling global change require geodetic reference frames with an order of accuracy higher than the magnitude of the effects to be actually studied and with high consistency and reliability worldwide. The International Association of Geodesy, taking care of providing a precise geodetic infrastructure for monitoring the Earth system, promotes the implementation of an integrated global geodetic reference frame that provides a reliable frame for consistent analysis and modelling of global phenomena and processes affecting the Earth's gravity field, the Earth's surface geometry and the Earth's rotation. The definition, realization, maintenance and wide utilization of the International Terrestrial Reference System guarantee a globally unified geometric reference frame with an accuracy at the millimetre level. An equivalent high-precision global physical reference frame that supports the reliable description of changes in the Earth's gravity field (such as sea level variations, mass displacements, processes associated with geophysical fluids) is missing. This paper addresses the theoretical foundations supporting the implementation of such a physical reference surface in terms of an International Height Reference System and provides guidance for the coming activities required for the practical and sustainable realization of this system. Based on conceptual approaches of physical geodesy, the requirements for a unified global height reference system are derived. In accordance with the practice, its realization as the International Height Reference Frame is designed. Further steps for the implementation are also proposed.

    The IAEA nuclear data section, in co-operation with several national nuclear data centres and research groups, has created the first version of an internationally available fusion evaluated nuclear data library (FENDL-1). The FENDL library has been selected to serve as a comprehensive source of processed and tested nuclear data tailored to the requirements of the engineering design activity (EDA) of the ITER project and other fusion-related development projects. The present version of FENDL consists of the following sublibraries covering the necessary nuclear input for all physics and engineering aspects of the material development, design, operation and safety of the ITER project in its current EDA phase: FENDL/A-1.1: neutron activation cross-sections, selected from different available sources, for 636 nuclides, FENDL/D-1.0: nuclear decay data for 2900 nuclides in ENDF-6 format, FENDL/DS-1.0: neutron activation data for dosimetry by foil activation, FENDL/C-1.0: data for the fusion reactions D(d,n), D(d,p), T(d,n), T(t,2n), He-3(d,p) extracted from ENDF/B-6 and processed, FENDL/E-1.0:data for coupled neutron-photon transport calculations, including a data library for neutron interaction and photon production for 63 elements or isotopes, selected from ENDF/B-6, JENDL-3, or BROND-2, and a photon-atom interaction data library for 34 elements. The benchmark validation of FENDL-1 as required by the customer, i.e. the ITER team, is considered to be a task of high priority in the coming months. The well tested and validated nuclear data libraries in processed form of the FENDL-2 are expected to be ready by mid 1996 for use by the ITER team in the final phase of ITER EDA after extensive benchmarking and integral validation studies in the 1995-1996 period. The FENDL data files can be electronically transferred to users from the IAEA nuclear data section online system through INTERNET.

    To present valid head circumference (HC) percentiles from early infancy to 18 years and to compare them with percentiles currently used in Germany by Prader, as well as to international WHO and CDC references. Nationally representative sample of 17,158 children and adolescents aged 0.25-17.98 years (KiGGS study 2003-2006) with standardized HC measurement. HC references were created using Cole's LMS method. The median growth of HC is largest in the first year of life. Adult HC is reached at age 16 years in girls, while in boys, HC growth continues through age 17 years and adult HC have to be derived from future KiGGS follow-up examinations. KiGGS percentiles are quite similar from early infancy to early school age compared to older Prader references, but higher thereafter (maximum difference of median HC: girls 1.4 cm, boys 0.9 cm). KiGGS percentiles are also higher than WHO and CDC percentiles over most of the compared age range, but differences are less pronounced compared to Prader. The KiGGS HC references presented here for boys and girls aged 4 months through 17 years are more valid than currently used German references. Because of the similarity of KiGGS and the currently used reference by Prader in early infancy, the currently used Prader reference for 0-4 months could complement KiGGS to cover the entire age range from birth to the end of adolescence. © 2011 The Author(s)/Acta Paediatrica © 2011 Foundation Acta Paediatrica.

    2017-11-01

    Full Text Available The article is aimed at generalizing the foreign experience of implementing public procurement, analyzing peculiarities of organizational, normative and procedural provision of public procurement in the Member States of the European Union. The relevance of the research topic is due to the need to harmonize the procurement policy of the Government of Ukraine with the international legal framework and with broad political objectives within the European integration strategy. The organizational framework and principles of implementing public procurement in the EU Member States were analyzed. Special attention was paid to normative provision of public procurement by the EU Member States; peculiarities of the use of national or harmonized rules of public procurement in accordance with the amount of the procurement contract; restrictions and conditions for public authorities in the selection of applicants for bidding. Five types of public procurement procedures used in the EU have been characterized, namely: open procedure, limited procedure, negotiation procedure, competitive dialog, electronic auctions. The need to address the social and legal aspects of public procurement in international practice has been substantiated and the possibilities for resolving these problems have been presented.

  17. [International reference prices and cost minimization analysis for the regulation of medicine prices in Colombia].

    2011-01-01

    To suggest a scheme of decision making on pricing for medicines that are part of Free Regulated Regime, a regulation way of the pharmaceutical pricing policy in Colombia. It includes two regulation tools: international reference prices and a cost minimization analysis methodology. Following the current pricing policy, international reference prices were built with data from five countries for selected medicines, which are under Free Regulated Regime. The cost minimization analysis methodology includes selection of those medicines under Free Regulated Regime with possible comparable medicines, selection of comparable medicines, and treatment costs evaluation. As a result of the estimate of International Reference Prices, four medicines showed in the domestic pharmaceutical market a bigger price than the Reference Price. A scheme of decision-making was design containing two possible regulation tools for medicines that are part of Free Regulated Regime: estimate of international reference prices and cost minimization analysis methodology. This diagram would be useful to assist the pricing regulation of Free Regulated Regime in Colombia. As present results shows, international reference prices make clear when domestic prices are higher than those of reference countries. In the current regulation of pharmaceutical prices in Colombia, the international reference price has been applied for four medicines. Would be suitable to extend this methodology to other medicines of high impact on the pharmaceutical expenditure, in particular those covered by public funding. The availability of primary sources about treatment costs in Colombia needs to be improved as a requirement to develop pharmaco-economic evidence. SISMED is an official database that represents an important primary source of medicines prices in Colombia. Nevertheless, having into account that SISMED represents an important advantage of transparency in medicines prices, it needs to be improved in quality and data

    2012-01-01

    National European growth references differ. We aimed to convert (harmonize) currently used charts into a single unified interchangeable LMS format for each European nation. Nine currently used national European growth references from Belgium (2009), France (1979), Poland (2001), Sweden (2002), Switzerland (1989), the UK (1990), Italy (2006) and Germany (1979 and 1997) were harmonized and compared with the international WHO child growth standards and WHO growth reference data for 5-19 years. European growth charts can be harmonized. The approach appears useful as height, and body mass index (BMI) is inappropriately represented by WHO references. European height references exhibit warping when plotted against the WHO reference. The French appears too short, the other Europeans too tall. Also, the BMI is not appropriately represented by the WHO references. Harmonizing references is a novel, convenient and cost-effective approach for converting historic and/or incomplete local or national growth reference charts into a unified interchangeable LMS format. Harmonizing facilitates producing growth references 'on demand', for limited regional purposes, for ethnically, socio-economically or politically defined minorities, but also for matching geographically different groups of children and adolescents for international growth and registry studies. © 2011 The Author(s)/Acta Paediatrica © 2011 Foundation Acta Paediatrica.

  1. One hundred prime references on hydrogeochemical and stream sediment surveying for uranium as internationally practiced, including 60 annotated references

    International Nuclear Information System (INIS)

    Sharp, R.R. Jr.; Bolivar, S.L.

    1981-04-01

    The United States Department of Energy (DOE), formerly the US ERDA, has initiated a nationwide Hydrogeochemical and Stream Sediment Reconnaissance (HSSR). This program is part of the US National Uranium Resource Evaluation, designed to provide an improved estimate for the availability and economics of nuclear fuel resources and make available to industry information for use in exploration and development of uranium resources. The Los Alamos National Laboratory is responsible for completing the HSSR in Rocky Mountain states of New Mexico, Colorado, Wyoming, and Montana and in the state of Alaska. This report contains a compilation of 100 prime references on uranium hydrogeochemical and stream sediment reconnaissance as internationally practiced prior to 1977. The major emphasis in selection of these references was directed toward constructing a HSSR program with the purpose of identifying uranium in the Los Alamos National Laboratory area of responsibility. The context of the annotated abstracts are the authors' concept of what the respective article contains relative to uranium geochemistry and hydrogeochemical and stream sediment surveying. Consequently, in many cases, significant portions of the original articles are not discussed. The text consists of two parts. Part I contains 100 prime references, alphabetically arranged. Part II contains 60 select annotated abstracts, listed in chronological order

  2. International experience with urban infrastructure development financing

    2014-02-01

    Full Text Available The paper substantiates the need for scientific studying the state of local infrastructure financing as well as efficient management of the existing infrastructure facilities. It is noted that under the influence of such factors as globalization, urbanization and information revolution the value of the city and role thereof in society are increasing. Based on analysis of the budget and demographic indices it has been proven that Kyiv, as the capital, occupies a unique place in the economic life of Ukraine, while being the country's financial and investment centre. It has been asserted that the critical level of the city's key infrastructure deterioration indicates lack of adequate municipal management in this field. The paper also asserts a high level of monopolization regarding housing and communal services, whereas also provides substantiation of the need for developing new competitive financing mechanisms to be applied. Existence of significant disparities between development of the city and construction of the essential transport infrastructure has been demonstrated with the said fact being due to incompliance of the borrowed finances with real investment needs. Given the international experience, the methods of upgrading the existing city infrastructure as well as sources of financial support for the new infrastructure projects have been suggested

  3. Impact of quasar proper motions on the alignment between the International Celestial Reference Frame and the Gaia reference frame

    Science.gov (United States)

    Liu, J.-C.; Malkin, Z.; Zhu, Z.

    2018-03-01

    The International Celestial Reference Frame (ICRF) is currently realized by the very long baseline interferometry (VLBI) observations of extragalactic sources with the zero proper motion assumption, while Gaia will observe proper motions of these distant and faint objects to an accuracy of tens of microarcseconds per year. This paper investigates the difference between VLBI and Gaia quasar proper motions and it aims to understand the impact of quasar proper motions on the alignment of the ICRF and Gaia reference frame. We use the latest time series data of source coordinates from the International VLBI Service analysis centres operated at Goddard Space Flight Center (GSF2017) and Paris observatory (OPA2017), as well as the Gaia auxiliary quasar solution containing 2191 high-probability optical counterparts of the ICRF2 sources. The linear proper motions in right ascension and declination of VLBI sources are derived by least-squares fits while the proper motions for Gaia sources are simulated taking into account the acceleration of the Solar system barycentre and realistic uncertainties depending on the source brightness. The individual and global features of source proper motions in GSF2017 and OPA2017 VLBI data are found to be inconsistent, which may result from differences in VLBI observations, data reduction and analysis. A comparison of the VLBI and Gaia proper motions shows that the accuracies of the components of rotation and glide between the two systems are 2-4 μas yr- 1 based on about 600 common sources. For the future alignment of the ICRF and Gaia reference frames at different wavelengths, the proper motions of quasars must necessarily be considered.

    Since no growth standards for adolescents exist and a single reference applicable everywhere is still in debate, it is recognized that the best reference should be derived from the growth pattern of the healthy population that will use it. In 2007 a study developed references for body mass index for 12th to 18th y Bolivian school adolescent (BAP. To compare nutritional status outcomes applying BMI references from the BAP, the Center for Disease Control and Prevention CDC 2000, the International Task Force (IOTF), and the 2007 WHO, to determine appropriateness of use in Bolivian adolescents. References were applied in 3306 adolescents, 45.0% male, 55% female, 12th to 18th y selected from a nationally representative sample. Main findings reveal that the CDC and the 2007 WHO underestimate underweight (preferences overestimate overweight (preferences for the use of BAP in Bolivia which reflects its healthy adolescent population growth pattern. International references may lead to incorrect conclusions when applied on Bolivian adolescents. They could deflect efforts from population which need prompt intervention and mislead treatments and budget to unnecessary ones. We recommend validation of international references where appropriate until a standard is released.

    2014-01-01

    Since the early 1950s, the number of international measurement standards for anchoring stable isotope delta scales has mushroomed from 3 to more than 30, expanding to more than 25 chemical elements. With the development of new instrumentation, along with new and improved measurement procedures for studying naturally occurring isotopic abundance variations in natural and technical samples, the number of internationally distributed, secondary isotopic reference materials with a specified delta value has blossomed in the last six decades to more than 150 materials. More than half of these isotopic reference materials were produced for isotope-delta measurements of seven elements: H, Li, B, C, N, O, and S. The number of isotopic reference materials for other, heavier elements has grown considerably over the last decade. Nevertheless, even primary international measurement standards for isotope-delta measurements are still needed for some elements, including Mg, Fe, Te, Sb, Mo, and Ge. It is recommended that authors publish the delta values of internationally distributed, secondary isotopic reference materials that were used for anchoring their measurement results to the respective primary stable isotope scale.

  1. International boundary experiences by the United Nations

    Science.gov (United States)

    Kagawa, A.

    2013-12-01

    Over the last few decades, the United Nations (UN) has been approached by Security Council and Member States on international boundary issues. The United Nations regards the adequate delimitation and demarcation of international boundaries as a very important element for the maintenance of peace and security in fragile post-conflict situations, establishment of friendly relationships and cross-border cooperation between States. This paper will present the main principles and framework the United Nations applies to support the process of international boundary delimitation and demarcation activities. The United Nations is involved in international boundary issues following the principle of impartiality and neutrality and its role as mediator. Since international boundary issues are multi-faceted, a range of expertise is required and the United Nations Secretariat is in a good position to provide diverse expertise within the multiple departments. Expertise in different departments ranging from legal, political, technical, administrative and logistical are mobilised in different ways to provide support to Member States depending on their specific needs. This presentation aims to highlight some of the international boundary projects that the United Nations Cartographic Section has been involved in order to provide the technical support to different boundary requirements as each international boundary issue requires specific focus and attention whether it be in preparation, delimitation, demarcation or management. Increasingly, the United Nations is leveraging geospatial technology to facilitate boundary delimitation and demarcation process between Member States. Through the presentation of the various case studies ranging from Iraq - Kuwait, Israel - Lebanon (Blue Line), Eritrea - Ethiopia, Cyprus (Green Line), Cameroon - Nigeria, Sudan - South Sudan, it will illustrate how geospatial technology is increasingly used to carry out the support.

    2001-01-01

    A key aspect of electricity industry reorganization is transmission pricing because it heavily influences the degree of effective competition in 'liberalized' electricity markets. this paper presents an overview transmission pricing models, of issues related to an effective design of a transmission pricing approach, and presents approaches implemented internationally. A conclusion is that, due to the great number of institutional designs of electricity market organizations, particularly in Europe, it will be difficult to design/implement a model of cross-border transmission pricing that is capable of inducing a high degree of non-discriminatory international competition in electricity markets.

    Selecting internal references is important for normalizing the loading quantity of samples in quantitative reverse-transcription PCR (qRT-PCR). In the present study, a systematic evaluation of reference genes among nine hepatocellular carcinoma (HCC) cell lines was conducted. After screening the microarray assay data of ten HCC cell lines, 19 candidate reference genes were preselected and then evaluated by qRT-PCR, together with ACTB, GAPDH, HPRT1 and TUBB The expression evenness of these candidate genes was evaluated using RefFinder. The stabilities of the reference genes were further evaluated under different experimental perturbations in Huh-7 and MHCC-97L, and the applicability of the reference genes was assessed by measuring the mRNA expression of CCND1, CCND3, CDK4 and CDK6 under sorafenib treatment in Huh-7. Results showed that TFG and SFRS4 are among the most reliable reference genes, and ACTB ranks third and acts quite well as a classical choice, whereas GAPDH, HPRT1 and TUBB are not proper reference genes in qRT-PCR assays among the HCC cell lines. SFRS4, YWHAB, SFRS4 and CNPY3 are the most stable reference genes of the MHCC-97L under the perturbations of chemotherapy, oxidative stress, starvation and hypoxia respectively, whereas YWHAB is the most stable one of Huh-7 under all perturbations. GAPDH is recommended as a reference gene under chemotherapy perturbations. YWHAB and UBE2B, TMED2 and TSFM , and GAPDH and TSFM are the two best reference genes under oxidative stress, starvation and hypoxia perturbations respectively. TSFM is stable in both cell lines across all the perturbations. © 2017 The Author(s).

    This paper describes the methodology of calculating the internal dose conversion coefficient in order to assess the radiological impact on non-human species. This paper also presents the internal dose conversion coefficients of 25 radionuclides ( 3 H, 7 Be, 14 C, 40 K, 51 Cr, 54 Mn, 59 Fe, 58 Co, 60 Co, 65 Zn, 90 Sr, '9 5 Zr, 95 Nb, 99 Tc, 106 Ru, 129 I, 131 I, 136 Cs, 137 Cs, 140 Ba, 140 La, 144 Ce, 238 U, 239 Pu, 240 Pu) for domestic seven reference animals (roe deer, rat, frog, snake, Chinese minnow, bee, and earthworm) and one reference plant (pine tree). The uniform isotropic model was applied in order to calculate the internal dose conversion coefficients. The calculated internal dose conversion coefficient (μGyd -1 per Bqkg -1 ) ranged from 10 -6 to 10 -2 according to the type of radionuclides and organisms studied. It turns out that the internal does conversion coefficient was higher for alpha radionuclides, such as 238 U, 239 Pu, and 240 Pu, and for large organisms, such as roe deer and pine tree. The internal dose conversion coefficients of 239 Pu, 240 Pu, 238 U, 14 C, 3 H and 99 Tc were independent of the organism

    Several distributions of country-specific blood pressure (BP) percentiles by sex, age, and height for children and adolescents have been established worldwide. However, there are no globally unified BP references for defining elevated BP in children and adolescents, which limits international comparisons of the prevalence of pediatric elevated BP. We aimed to establish international BP references for children and adolescents by using 7 nationally representative data sets (China, India, Iran, Korea, Poland, Tunisia, and the United States). Data on BP for 52 636 nonoverweight children and adolescents aged 6 to 19 years were obtained from 7 large nationally representative cross-sectional surveys in China, India, Iran, Korea, Poland, Tunisia, and the United States. BP values were obtained with certified mercury sphygmomanometers in all 7 countries by using standard procedures for BP measurement. Smoothed BP percentiles (50th, 90th, 95th, and 99th) by age and height were estimated by using the Generalized Additive Model for Location Scale and Shape model. BP values were similar between males and females until the age of 13 years and were higher in males than females thereafter. In comparison with the BP levels of the 90th and 95th percentiles of the US Fourth Report at median height, systolic BP of the corresponding percentiles of these international references was lower, whereas diastolic BP was similar. These international BP references will be a useful tool for international comparison of the prevalence of elevated BP in children and adolescents and may help to identify hypertensive youths in diverse populations. © 2015 American Heart Association, Inc.

    2018-03-16

    Internal radiation dose estimates for diagnostic nuclear medicine procedures are typically calculated for a reference individual. Resultantly, there is uncertainty when determining the organ doses to patients who are not at 50th percentile on either height or weight. This study aims to better personalize internal radiation dose estimates for individual patients by modifying the dose estimates calculated for reference individuals based on easily obtainable morphometric characteristics of the patient. Phantoms of different sitting heights and waist circumferences were constructed based on computational reference phantoms for the newborn, 10-year-old, and adult. Monoenergetic photons and electrons were then simulated separately at 15 energies. Photon and electron specific absorbed fractions (SAFs) were computed for the newly constructed non-reference phantoms and compared to SAFs previously generated for the age-matched reference phantoms. Differences in SAFs were correlated to changes in sitting height and waist circumference to develop scaling factors that could be applied to reference SAFs as morphometry corrections. A further set of arbitrary non-reference phantoms were then constructed and used in validation studies for the SAF scaling factors. Both photon and electron dose scaling methods were found to increase average accuracy when sitting height was used as the scaling parameter (~11%). Photon waist circumference-based scaling factors showed modest increases in average accuracy (~7%) for underweight individuals, but not for overweight individuals. Electron waist circumference-based scaling factors did not show increases in average accuracy. When sitting height and waist circumference scaling factors were combined, modest average gains in accuracy were observed for photons (~6%), but not for electrons. Both photon and electron absorbed doses are more reliably scaled using scaling factors computed in this study. They can be effectively scaled using sitting

  11. Uncertainty evaluation in normalization of isotope delta measurement results against international reference materials.

    Isotope delta measurements are normalized against international reference standards. Although multi-point normalization is becoming a standard practice, the existing uncertainty evaluation practices are either undocumented or are incomplete. For multi-point normalization, we present errors-in-variables regression models for explicit accounting of the measurement uncertainty of the international standards along with the uncertainty that is attributed to their assigned values. This manuscript presents framework to account for the uncertainty that arises due to a small number of replicate measurements and discusses multi-laboratory data reduction while accounting for inevitable correlations between the laboratories due to the use of identical reference materials for calibration. Both frequentist and Bayesian methods of uncertainty analysis are discussed.

    Purpose The goal of this research was to examine whether phonological familiarity exerts different effects on novel word learning for familiar vs. unfamiliar referents, and whether successful word-learning is associated with increased second-language experience. Method Eighty-one adult native English speakers with various levels of Spanish knowledge learned phonologically-familiar novel words (constructed using English sounds) or phonologically-unfamiliar novel words (constructed using non-English and non-Spanish sounds) in association with either familiar or unfamiliar referents. Retention was tested via a forced-choice recognition-task. A median-split procedure identified high-ability and low-ability word-learners in each condition, and the two groups were compared on measures of second-language experience. Results Findings suggest that the ability to accurately match newly-learned novel names to their appropriate referents is facilitated by phonological familiarity only for familiar referents but not for unfamiliar referents. Moreover, more extensive second-language learning experience characterized superior learners primarily in one word-learning condition: Where phonologically-unfamiliar novel words were paired with familiar referents. Conclusions Together, these findings indicate that phonological familiarity facilitates novel word learning only for familiar referents, and that experience with learning a second language may have a specific impact on novel vocabulary learning in adults.

  19. Determinants of International Migration: The Nigerian Experience

    2014-01-01

    Full Text Available This paper examines some determinants of international migration in Nigeria using annual time series data spanning the period 1991–2011. Using ordinary least square regression method, the results indicate that the level of unemployment, migrants’ remittances and population growth are the key determinants of emigration from Nigeria to other countries, statistically significant at 0.01 level.In a country where unemployment rate is very high, this movement is likely to help in reducing pressures on the labour market. Migrants’ remittances might also help in alleviating poverty within households. Migrants’ remittance to Nigeria has surpassed both Foreign Direct Investment and Net Official Development Assistance inflows, making it one amongst the major sources of foreign earnings to Nigeria. Nigerians will continue to migrate to other parts of the world so long as the reasons or causes for their movement are not fully addressed i.e. if political and socioeconomic issues in the country do not improve. The Nigerian government should as a matter of urgency, create better jobs and conducive environment in order to stop people from migrating while at the same time encouraging its skilled labour abroad to return home to help in national development.

    In 2009, the International Soil Moisture Network (ISMN; http:www.ipf.tuwien.ac.at) was initiated as a platform to support calibration and validation of soil moisture products from remote sensing and land surface models, and to advance studies on the behavior of soil moisture over space and time. This international initiative is fruit of continuing coordinative efforts of the Global Energy and Water Cycle Experiment (GEWEX) in cooperation with the Group of Earth Observation (GEO) and the Committee on Earth Observation Satellites (CEOS). The decisive financial incentive was given by the European Space Agency (ESA) who considered the establishment of the network critical for optimizing the soil moisture products from the Soil Moisture and Ocean Salinity (SMOS) mission. The ISMN collects and harmonizes ground-based soil moisture data sets from a large variety of individually operating networks and makes them available through a centralized data portal. Meanwhile, almost 6000 soil moisture data sets from over 1300 sites, distributed among 34 networks worldwide, are contained in the database. The steadily increasing number of organizations voluntarily contributing to the ISMN, and the rapidly increasing number of studies based on the network show that the portal has been successful in reaching its primary goal to promote easy data accessibility to a wide variety of users. Recently, several updates of the system were performed to keep up with the increasing data amount and traffic, and to meet the requirements of many advanced users. Many datasets from operational networks (e.g., SCAN, the US Climate Reference Network, COSMOS, and ARM) are now assimilated and processed in the ISMN on a fully automated basis in near-real time. In addition, a new enhanced quality control system is currently being implemented. This presentation gives an overview of these recent developments, presents some examples of important scientific results based on the ISMN, and sketches an outlook for

  13. International experiences with power supply crises

    International Nuclear Information System (INIS)

    2002-01-01

    Many so-called deregulated power markets experience a hardened energy and power balance and some have had supply crises. This report discusses the crises, their impacts and their causes as well as the measures taken by the authorities to solve the crises. It also considers the similarities or dissimilarities with respect to the situation in Norway the winter 2002/2003. Like Norway, many of the countries have a considerable share of hydroelectric power. It is found, however, that the dependence on water of its own is not the reason for the crises, but that the inflow conditions give the market greater challenges. Furthermore, the Norwegian market has greater flexibility in the consumption, greater import capacity, better price security possibilities and less problems with market power than most of the countries here considered. Various factors influence a country's power consumption and production capacity. Economic growth and the availability of inexpensive power contribute to accelerate the consumption, while predictable external conditions and sufficient expected investment earnings are necessary to achieve an increase of the capacity - both through new investments and attendance to existing capacity. In a smooth power market there must be a certain correspondence between consumption and installed capacity, and the capacity must be such that it can cover the continuous demand for power and at the same time be flexible enough to deliver power at peak loads. This is also true of the transmission capacity. In addition, some extra capacity must be available for unexpected events. The basic problem is, in any power market, that the consumption may rise fast, while the investments in new capacity typically occurs in leaps, with long and costly construction phases. Many countries have lately experienced a hardening of the balance between consumption and capacity and so have been vulnerable to unexpected increases in consumption or resource failure. This was also the

    Few studies assess the transition from medical student to intern and there is limited understanding of what measures are required to assist intern development. The aim of the study was to assess interns' perception of their preparedness before commencing and on completion of their rotation in General Medicine, and their attitudes towards educational experiences at a tertiary metropolitan teaching hospital. Self-assessed preparedness for the General Medical internship and educational experiences were evaluated using a quantitative 5-point scale (1 = low score and 5 = high score) and qualitatively through interview, on interns based at St Vincent's Hospital (Melbourne). Data were collected at the beginning and at the end of each 10-week rotation (n = 25). Before commencement of the rotation, the interns identified areas where they felt inadequately prepared, particularly resuscitation skills and medico-legal aspects. When resurveyed at the completion of their 10-week rotation, the interns felt they had been better prepared for their role than they initially perceived, both generally and in specific aspects. Nine out of 16 parameters showed a significant increase in preparedness score at week 10 compared to week 1. The educational experiences most valued were peer driven education sessions and informal registrar teaching. Formal consultant teaching and online learning were perceived as being the least useful. Interns at St Vincent's Hospital have been adequately prepared for their role in General Medicine, although many realize this only in retrospect. Deficiencies in educational opportunities for interns have been uncovered that emphasize areas of attention for medical educators.

    Continuing our program of spectroscopic observations of International Celestial Reference Frame (ICRF) sources, we present redshifts for 120 quasars and radio galaxies. Data were obtained with five telescopes: the 3.58 m European Southern Observatory New Technology Telescope, the two 8.2 m Gemini telescopes, the 2.5 m Nordic Optical Telescope (NOT), and the 6.0 m Big Azimuthal Telescope of the Special Astrophysical Observatory in Russia. The targets were selected from the International VLBI Service for Geodesy and Astrometry candidate International Celestial Reference Catalog which forms part of an observational very long baseline interferometry (VLBI) program to strengthen the celestial reference frame. We obtained spectra of the potential optical counterparts of more than 150 compact flat-spectrum radio sources, and measured redshifts of 120 emission-line objects, together with 19 BL Lac objects. These identifications add significantly to the precise radio-optical frame tie to be undertaken by Gaia, due to be launched in 2013, and to the existing data available for analyzing source proper motions over the celestial sphere. We show that the distribution of redshifts for ICRF sources is consistent with the much larger sample drawn from Faint Images of the Radio Sky at Twenty cm (FIRST) and Sloan Digital Sky Survey, implying that the ultra-compact VLBI sources are not distinguished from the overall radio-loud quasar population. In addition, we obtained NOT spectra for five radio sources from the FIRST and NRAO VLA Sky Survey catalogs, selected on the basis of their red colors, which yielded three quasars with z > 4.

  20. Calibrating NIST SRM 683 as A New International Reference Standard for Zn Isotopes

    Science.gov (United States)

    Yang, Y.; Zhang, X.; Yu, H.; Huang, F.

    2017-12-01

    Zinc isotopes have been widely applied in the cosmochemical, geochemical, and environmental studies (Moynier et al. 2017). Obtaining precise Zn isotopic data for inter-laboratory comparison is a prerequisite to these applications. Currently, the JMC3-0749L is the primary reference standard for Zn isotopes (Albarède 2004), but it is not commercially available now. Thus, it is necessary to calibrate a new international primary reference standard for Zn isotopic analysis. Chen et al. (2016) showed that NIST SRM 683 (a pure Zn metal nugget of 140 grams) has a δ66ZnJMC of 0.12‰, which is falling within the range of natural Zn isotopic compositions, and it may a good candidate for the next generation of international reference standard (Chen et al. 2016). In order to further examine whether NIST SRM 683 has a homogeneous Zn isotopic composition, we measured more NIST SRM 683 by double-spike methods using MC-ICPMS (Conway et al. 2013). The metal nuggets of NIST SRM 683 were intensively sampled by micro-drilling. Zinc isotope analyses for two nuggets show that they have δ66Zn of 0.14 ± 0.02‰ (2SD, N = 32) and 0.13 ± 0.02‰ (2SD, N = 33), respectively. These values are similar to those of two Zn metal nuggets (0.11 ± 0.02‰ vs. 0.12 ± 0.02‰) reported previously by Chen et al. (2016). We fully dissolved one nugget, producing pure Zn solution with identical Zn isotopic composition with the drilling samples. All results strongly support that NIST SRM 683 is homogeneous in Zn isotopic compositions which could be an ideal candidate for the next reference for Zn isotopes. Tests on more metal nuggets will be performed in a few months for further confirming the Zn isotope compositions and homogeneity. Reference: Albarède et al., 2004.

    The article reports results from the largest international dose survey in paediatric computed tomography (CT) in 32 countries and proposes international diagnostic reference levels (DRLs) in terms of computed tomography dose index (CTDI vol ) and dose length product (DLP). It also assesses whether mean or median values of individual facilities should be used. A total of 6115 individual patient data were recorded among four age groups: <1 y, >1-5 y, >5-10 y and >10-15 y. CTDI w , CTDI vol and DLP from the CT console were recorded in dedicated forms together with patient data and technical parameters. Statistical analysis was performed, and international DRLs were established at rounded 75. percentile values of distribution of median values from all CT facilities. The study presents evidence in favour of using median rather than mean of patient dose indices as the representative of typical local dose in a facility, and for establishing DRLs as third quartile of median values. International DRLs were established for paediatric CT examinations for routine head, chest and abdomen in the four age groups. DRLs for CTDI vol are similar to the reference values from other published reports, with some differences for chest and abdomen CT. Higher variations were observed between DLP values, based on a survey of whole multi-phase exams. It may be noted that other studies in literature were based on single phase only. DRLs reported in this article can be used in countries without sufficient medical physics support to identify non-optimised practice. Recommendations to improve the accuracy and importance of future surveys are provided. (authors)

    The purpose of this research is to study the use of an internal reference standard for fat- and muscle as a replacement for an external reference standard with a phantom. By using a phantomless internal reference standard, Hounsfield unit (HU) measurements of various tissues can potentially be assessed in patients with a CT scan of the pelvis without an added phantom at time of CT acquisition. This paves the way for development of a tool for quantification of the change in tissue density in one patient over time and between patients. This could make every CT scan made without contrast available for research purposes. Fifty patients with unilateral metal-on-metal total hip replacements, scanned together with a calibration reference phantom used in bone mineral density measurements, were included in this study. On computed tomography scans of the pelvis without the use of intravenous iodine contrast, reference values for fat and muscle were measured in the phantom as well as within the patient's body. The conformity between the references was examined with the intra-class correlation coefficient. The mean HU (± SD) of reference values for fat for the internal- and phantom references were -91.5 (±7.0) and -90.9 (±7.8), respectively. For muscle, the mean HU (± SD) for the internal- and phantom references were 59.2 (±6.2) and 60.0 (±7.2), respectively. The intra-class correlation coefficients for fat and muscle were 0.90 and 0.84 respectively and show excellent agreement between the phantom and internal references. Internal references can be used with similar accuracy as references from an external phantom. There is no need to use an external phantom to asses CT density measurements of body tissue.

    The measurement of volatile organic compound (VOC) emissions from building products and materials by manufacturers and testing laboratories, and the use of the test results for labeling programs, continue to expand. One issue that hinders wide acceptance for chamber product testing is the lack of a reference material to validate test chamber performance. To meet this need, the National Institute of Standards and Technology (NIST) and Virginia Tech (VT) have developed a prototype reference material that emits a single VOC similar to the emissions of a diffusion-controlled building product source with a dynamic emissions profile. The prototype material has undergone extensive testing at NIST and a pilot interlaboratory study (ILS) with four laboratories. The next development step is an evaluation of the prototype source in multiple-sized chambers of 14 laboratories in seven countries. Each laboratory was provided duplicate specimens and a test protocol. Study results identified significant issues related to the need to store the source at a subzero Celsius temperature until tested and possible inconsistencies in large chambers. For laboratories using a small chamber and meeting all the test method criteria, the results were very encouraging with relative standard deviations ranging from 5% to 10% across the laboratories. Currently, the chamber performance of laboratories conducting product VOC emissions testing is assessed through interlaboratory studies (ILS) using a source with an unknown emission rate. As a result, laboratory proficiency can only be based on the mean and standard deviation of emission rates measured by the participating ILS laboratories. A reference material with a known emission rate has the potential to provide an independent assessment of laboratory performance as well as improve the quality of interlaboratory studies. Several international laboratories with different chamber testing systems demonstrated the ability to measure the emission rate

    Prader Willi and Angelman syndromes are clinically distinct genetic disorders both mapping to chromosome region 15q11-q13, which are caused by a loss of function of paternally or maternally inherited genes in the region, respectively. With clinical diagnosis often being difficult, particularly in infancy, confirmatory genetic diagnosis is essential to enable clinical intervention. However, the latter is challenged by the complex genetics behind both disorders and the unmet need for characterised reference materials to aid accurate molecular diagnosis. With this in mind, a panel of six genotyping reference materials for Prader Willi and Angelman syndromes was developed, which should be stable for many years and available to all diagnostic laboratories. The panel comprises three Prader Willi syndrome materials (two with different paternal deletions, and one with maternal uniparental disomy (UPD)) and three Angelman syndrome materials (one with a maternal deletion, one with paternal UPD or an epigenetic imprinting centre defect, and one with a UBE3A point mutation). Genomic DNA was bulk-extracted from Epstein-Barr virus-transformed lymphoblastoid cell lines established from consenting patients, and freeze-dried as aliquots in glass ampoules. In total, 37 laboratories from 26 countries participated in a collaborative study to assess the suitability of the panel. Participants evaluated the blinded, triplicate materials using their routine diagnostic methods against in-house controls or externally sourced uncertified reference materials. The panel was established by the Expert Committee on Biological Standardization of the World Health Organization as the first International Genetic Reference Panel for Prader Willi and Angelman syndromes.

    An atomic oxygen fluence monitor was flown as part of the Materials International Space Station Experiment-6 (MISSE-6). The monitor was designed to measure the accumulation of atomic oxygen fluence with time as it impinged upon the ram surface of the MISSE 6B Passive Experiment Container (PEC). This was an active experiment for which data was to be stored on a battery-powered data logger for post-flight retrieval and analysis. The atomic oxygen fluence measurement was accomplished by allowing atomic oxygen to erode two opposing wedges of pyrolytic graphite that partially covered a photodiode. As the wedges of pyrolytic graphite erode, the area of the photodiode that is illuminated by the Sun increases. The short circuit current, which is proportional to the area of illumination, was to be measured and recorded as a function of time. The short circuit current from a different photodiode, which was oriented in the same direction and had an unobstructed view of the Sun, was also to be recorded as a reference current. The ratio of the two separate recorded currents should bear a linear relationship with the accumulated atomic oxygen fluence and be independent of the intensity of solar illumination. Ground hyperthermal atomic oxygen exposure facilities were used to evaluate the linearity of the ratio of short circuit current to the atomic oxygen fluence. In flight, the current measurement circuitry failed to operate properly, thus the overall atomic oxygen mission fluence could only be estimated based on the physical erosion of the pyrolytic graphite wedges. The atomic oxygen fluence was calculated based on the knowledge of the space atomic oxygen erosion yield of pyrolytic graphite measured from samples on the MISSE 2. The atomic oxygen fluence monitor, the expected result and comparison of mission atomic oxygen fluence based on the erosion of the pyrolytic graphite and Kapton H atomic oxygen fluence witness samples are presented in this paper.

    Background Little is known about the veterinary referral process and factors that contribute to positive outcomes. Objective To investigate equine referring veterinarians' (rDVMs') satisfaction with their most recent referral experience and compare rDVM and specialist perspectives. Sample 187 rDVMs and 92 specialists (referral care providers). Methods Cross‐sectional observational study. An online survey was administered to both rDVMs and specialists. Referring veterinarian satisfaction with their most recent referral experience was evaluated. Both rDVMs and specialists were asked to identify factors influencing a rDVM's decision where to refer, and the top 3 factors they perceive are barriers to referral care. Results Median rDVM satisfaction with their most recent referral care experience was 80 of 100 (mean, 75; range, 8–100). Referring veterinarians provided the lowest satisfaction score for the item asking about “The competition the referral hospital poses to your practice” (mean, 56.96; median, 62; range, 0–100). The top factor rDVMs identified as influencing their decision where to refer was “quality of care,” whereas specialists identified “quality of communication and updates from the clinician.” Referring veterinarians' top barrier to referral care was “high cost of referral care,” and for specialists was “poor service provided to the client by the referral hospital.” Conclusions and Clinical Importance Referring veterinarians generally were satisfied with referral care, but areas exist where rDVMs and specialists differ in what they view as important to the referral process. Exploring opportunities to overcome these differences is likely to support high quality care. PMID:29469978

    This report presents the internal and external dose conversion coefficients for domestic reference animals and plant, which are essential to assess the radiological impact of an environmental radiation on non-human species. To calculate the dose conversion coefficients, a uniform isotropic model and a Monte Carlo method for a photon transport simulation in environmental media with different densities have been applied for aquatic and terrestrial animals, respectively. In the modeling all the target animals are defined as a simple 3D elliptical shape. To specify the external radiation source it is assumed that aquatic animals are fully immersed in infinite and uniformly contaminated water, and the on-soil animals are living on the surface of a horizontally infinite soil source, and the in-soil organisms are living at the center of a horizontally infinite and uniformly contaminated soil to a depth of 50cm. A set of internal and external dose conversion coefficients for 8 Korean reference animals and plant (rat, roe-deer, frog, snake, Chinese minnow, bee, earthworm, and pine tree) are presented for 25 radionuclides ({sup 3}H, {sup 7}Be, {sup 14}C, {sup 40}K, {sup 51}Cr, {sup 54}Mn, {sup 59}Fe, {sup 58}Co, {sup 60}Co, {sup 65}Zn, {sup 90}Sr, {sup 95}Zr, {sup 95}Nb, {sup 99}Tc, {sup 106}Ru, {sup 129}I, {sup 131}I, {sup 136}Cs, {sup 137}Cs, {sup 140}Ba, {sup 140}La, {sup 144}Ce, {sup 238}U, {sup 239}Pu, and {sup 240}Pu)

    Materials International Space Station Experiment 7B (MISSE 7B) is the most recent in a series of experiments flown on the exterior of International Space Station for the purpose of determining the durability of materials and components in the space environment. A collaborative effort among the Department of Defense, the National Aeronautics and Space Administration, industry, and academia, MISSE 7B will be flying a number of NASA experiments designed to gain knowledge in the area of space environmental effects to mitigate risk for exploration missions. Consisting of trays called Passive Experiment Containers, the suitcase sized payload opens on hinges and allows active and passive experiments contained within to be exposed to the ram and wake or zenith and nadir directions in low Earth orbit, in essence, providing a test bed for atomic oxygen exposure, ultraviolet radiation exposure, charged particle radiation exposure, and thermal cycling. New for MISSE 7B is the ability to monitor experiments actively, with data sent back to Earth via International Space Station communications. NASA?s active and passive experiments cover a range of interest for the Agency. Materials relevant to the Constellation Program include: solar array materials, seal materials, and thermal protection system materials. Materials relevant to the Exploration Technology Development Program include: fabrics for spacesuits, materials for lunar dust mitigation, and new thermal control coatings. Sensors and components on MISSE 7B include: atomic oxygen fluence monitors, ultraviolet radiation sensors, and electro-optical components. In addition, fundamental space environmental durability science experiments are being flown to gather atomic oxygen erosion data and thin film polymer mechanical and optical property data relevant to lunar lander insulation and the James Web Space Telescope. This paper will present an overview of the NASA experiments to be flown on MISSE 7B, along with a summary of the

    Interest in high-quality integral benchmark data is increasing as efforts to quantify and reduce calculational uncertainties associated with advanced modeling and simulation accelerate to meet the demands of next generation reactor and advanced fuel cycle concepts. Two Organization for Economic Cooperation and Development (OECD) Nuclear Energy Agency (NEA) activities, the International Criticality Safety Benchmark Evaluation Project (ICSBEP), initiated in 1992, and the International Reactor Physics Experiment Evaluation Project (IRPhEP), initiated in 2003, have been identifying existing integral experiment data, evaluating those data, and providing integral benchmark specifications for methods and data validation for nearly two decades. Data provided by those two projects will be of use to the international reactor physics, criticality safety, and nuclear data communities for future decades. An overview of the IRPhEP and a brief update of the ICSBEP are provided in this paper.

    Child growth is internationally recognized as an important indicator of nutritional status and health in populations. This study was aimed to compare age- and gender-specific height, weight and BMI percentiles and nutritional status relative to the international growth references among Pakistani school-aged children. A population-based study was conducted with a multistage cluster sample of 1860 children aged five to twelve years in Lahore, Pakistan. Smoothed height, weight and BMI percentile curves were obtained and comparison was made with the World Health Organization 2007 (WHO) and United States' Centers for Disease Control and Prevention 2000 (USCDC) references. Over- and under-nutrition were defined according to the WHO and USCDC references, and the International Obesity Task Force (IOTF) cut-offs. Simple descriptive statistics were used and statistical significance was considered at P references. Mean differences from zero for height-, weight- and BMI-for-age z score values relative to the WHO and USCDC references were significant (P reference were closer to zero and the present study as compared to the USCDC reference. Mean differences between weight-for-age (0.19, 95% CI 0.10-0.30) and BMI-for-age (0.21, 95% CI 0.11-0.30) z scores relative to the WHO and USCDC references were significant. Over-nutrition estimates were higher (P reference as compared to the USCDC reference (17% vs. 15% overweight and 7.5% vs. 4% obesity) while underweight and thinness/wasting were lower (P reference as compared to the USCDC reference (7% vs. 12% underweight and 10% vs. 13% thinness). Significantly lower overweight (8%) and obesity (5%) prevalence and higher thinness grade one prevalence (19%) was seen with use of the IOTF cut-offs as compared to the WHO and USCDC references. Mean difference between height-for-age z scores and difference in stunting prevalence relative to the WHO and USCDC references was not significant. Pakistani school-aged children significantly differed

    Emission testing of products is currently a rapidly increasing field of measurement activity. Labeling procedures for construction products are based on such emission test chamber measurements, and hence, measurement performance should be verified. One possible route is to conduct testing of one material in different laboratories within a round robin test (RRT), ideally using homogeneous reference materials, which can be used within interlaboratory studies or as part of the quality management system to ensure comparable results. The applicability of a lacquer system with nine added VOCs (hexanal, styrene, n-decane, limonene, 2-ethyl-1-hexanol, N-methyl-α-pyrrolidone, 2-ethylhexyl acrylate, dimethyl phthalate, and n-hexadecane) was evaluated in an international RRT with 55 participating laboratories. An intralaboratory quality check confirmed the homogeneity and reproducibility of the lacquer material for most of the compounds (RSD 5%-6%), which was confirmed in the RRT. However, emissions varied for the polar compound N-methyl-α-pyrrolidone and the higher boiling compounds 1,2-dimethyl phthalate, and n-hexadecane which could be traced back to analytical issues. In the RRT, the interlaboratory relative standard deviations (RSDs) ranged from 30% to 65% for all participants but for reference laboratories the range was between 20% and 45%. © 2017 The Authors.

    The new international reference material IAEA-603 (calcite) for stable carbon and oxygen isotopes (δ 13 C and δ 18 O values) was released in 2016 to replace the previous reference material, NBS19 (exhausted). We examined the grain-scale isotopic variations in IAEA-603 for application to microscale isotopic analysis of carbonate samples. Individual grains of IAEA-603 were analyzed with an IsoPrime100 isotope ratio mass spectrometer with a customized continuous-flow gas preparation system (MICAL3c). The individual grains of IAEA-603 were observed by optical and scanning electron microscopy, and their observational characteristics (grain color and size) were compared with their stable isotope compositions. Translucent grains (main component of IAEA-603; grain weight, 4-132 μg) had homogeneous isotopic ratios, comparable with the grain-scale isotopic homogeneity of NBS 19. Their average δ 13 C and δ 18 O values were the same as the recommended values determined by the IAEA. Opaque (whitish) grains (1-2 per 100 grains; grain weight, 8-63 μg) were significantly more depleted in 13 C and 18 O than the translucent grains. Low-abundance opaque grains (1-2 grains out of 100 grains) have lower δ 13 C and δ 18 O values, suggesting that these grains should be eliminated when using IAEA-603 for single-grain (microscale) isotope analysis.

    Full Text Available Academic institutions of higher education, and especially Jesuit institutions, face the challenge of educating students who often face unique financial challenges. These challenges can have an impact on access to quality education and experience. Given our globalized environment, among these challenges is the opportunity for students to participate in a study-abroad experience while at the university. Today, through the use of technology it is possible for institutions of higher education to offer these collaborative learning experiences to those students who may not be able to travel. This paper will detail a pedagogical approach which emphasizes using collaborative online international engagement.

    This article summarizes the outcome of the discussions at the international workshop on nano reference values (NRVs), which was organized by the Dutch trade unions and employers' organizations and hosted by the Social Economic Council in The Hague in September 2011. It reflects the discussions of 80 international participants representing small- and medium-size enterprises (SMEs), large companies, trade unions, governmental authorities, research institutions, and non-governmental organizations (NGOs) from many European countries, USA, India, and Brazil. Issues that were discussed concerned the usefulness and acceptability of precaution-based NRVs as a substitute for health-based occupational exposure limits (OELs) and derived no-effect levels (DNELs) for manufactured nanoparticles (NPs). Topics concerned the metrics for measuring NPs, the combined exposure to manufactured nanomaterials (MNMs) and process-generated NPs, the use of the precautionary principle, the lack of information about the presence of nanomaterials, and the appropriateness of soft regulation for exposure control. The workshop concluded that the NRV, as an 8-h time-weighted average, is a comprehensible and useful instrument for risk management of professional use of MNMs with a dispersible character. The question remains whether NRVs, as advised for risk management by the Dutch employers' organization and trade unions, should be under soft regulation or that a more binding regulation is preferable.

    Undertaking of a complete audit of the service of mammography, as recommended by BI-RADS(®), in a private reference institution for breast cancer diagnosis in the city of São Paulo, SP, Brazil, and comparison of results with those recommended by the literature. Retrospective, analytical and cross-sectional study including 8,000 patients submitted to mammography in the period between April 2010 and March 2011, whose results were subjected to an internal audit. The patients were followed-up until December 2012. The radiological classification of 7,249 screening mammograms, according to BI-RADS, was the following: category 0 (1.43%), 1 (7.82%), 2 (80.76%), 3 (8.35%), 4 (1.46%), 5 (0.15%) and 6 (0.03%). The breast cancer detection ratio was 4.8 cases per 1,000 mammograms. Ductal carcinoma in situ was found in 22.8% of cases. Positive predictive values for categories 3, 4 and 5 were 1.3%, 41.3% and 100%, respectively. In the present study, the sensitivity of the method was 97.1% and specificity, 97.4%. The complete internal audit of a service of mammography is essential to evaluate the quality of such service, which reflects on an early breast cancer detection and reduction of mortality rates.

    In recent years there has been a greater focus on the management of patient doses. This effort has been driven by the realisation of both the increasing magnitude of patient doses and their variation both intra- and inter-nationally. Legislators and guidance-issuing bodies have developed the idea of 'Diagnostic Reference Levels' (DRL's). In particular, the European Union, in their Council Directive 97/43/Euratom, required Member States to develop DRL's. The UK Government, when consolidating this EU Directive into UK legislation, extended the concept of DRL's from a national to an employer level. However, the methodologies used for development of national and international DRL's do not translate to a local level and hence a new approach is required. This paper describes one particular approach made by a UK hospital to introduce 'Local DRL's' in such a manner as to aid the optimisation process. This approach utilises a dose index, based on the local patient population, which is monitored for trends. Any trend in patient dose triggers an investigation linked to the clinical audit system within the Clinical Radiology Department. It is the audit cycle that ensures a continuing move towards an optimised situation. Additional triggers may be employed such as large patient dose variations. (author)

    Full Text Available Orientation: The use of assessment centres (ACs has drastically increased over the past decade. However, ACs are constantly confronted with the lack of construct validity. One aspect of ACs that could improve the construct validity significantly is that of assessor training. Unfortunately untrained or poorly trained assessors are often used in AC processes. Research purpose: The purpose of this research was to evaluate a frame-of-reference (FOR programme to train intern psychometrists as assessors at an assessment centre. Motivation of study: The role of an assessor is important in an AC; therefore it is vital for an assessor to be able to evaluate and observe candidates’ behaviour adequately. Commencing with this training in a graduate psychometrist programme gives the added benefit of sending skilled psychometrists to the workplace. Research design, approach and method: A quantitative research approach was implemented, utilising a randomised pre-test-post-test comparison group design. Industrial Psychology postgraduate students (N = 22 at a South African university were used and divided into an experimental group (n = 11 and control group (n = 11. Three typical AC simulations were utilised as pre- and post-tests, and the ratings obtained from both groups were statistically analysed to determine the effect of the FOR training programme. Main findings: The data indicated that there was a significant increase in the familiarity of the participants with the one-on-one simulation and the group discussion simulation. Practical/managerial implications: Training intern psychometrists in a FOR programme could assist organisations in the appointment of more competent assessors. Contribution/value-add: To design an assessor training programme using FOR training for intern psychometrists in the South African context, specifically by incorporating this programme into the training programme for Honours students at universities.

    A variety of critical experiments were constructed of enriched uranium metal (oralloy ) during the 1960s and 1970s at the Oak Ridge Critical Experiments Facility (ORCEF) in support of criticality safety operations at the Y-12 Plant. The purposes of these experiments included the evaluation of storage, casting, and handling limits for the Y-12 Plant and providing data for verification of calculation methods and cross-sections for nuclear criticality safety applications. These included solid cylinders of various diameters, annuli of various inner and outer diameters, two and three interacting cylinders of various diameters, and graphite and polyethylene reflected cylinders and annuli. Of the hundreds of delayed critical experiments, only three experimental configurations are described here. They are internal graphite reflected metal uranium assemblies with three different diameter HEU annuli (15-9 inches, 15-7 inches and 13-7 inches). These experiments can be found in Reference 1 and in their associated logbook

    While over a million international students attend U.S. universities, there is little information to guide providers on their care. Differences in language and health beliefs can lead to misunderstandings and poor outcomes. The purpose of this study was to describe the health practices and healthcare experiences of international students before and after they move to the United States to carve out specific quality improvement activities at a student health center. International students volunteered to attend focus groups. Data were analyzed using text coding software (Dedoose) to identify salient themes that reflected participants' experiences. Participants (N = 19) identified four areas of health maintenance: exercise, nutrition, yearly checkups, and self-care for minor ailments. While participants described health care in their home countries as accessible and affordable, they described health care in the United States as less accessible, more expensive, and laden with communication mishaps. A broader educational message to international students, that is, how to maintain healthy habits in the United States and how to access/navigate U.S. health care, coupled with staff training on effective health communication and the use of interpreter services would enhance the health and healthcare experience of this vital population. ©2017 American Association of Nurse Practitioners.

    Lipoprotein(a) is an important predictor of cardiovascular disease risk. The lack of internationally accepted standardization has impeded the broad application of this lipoprotein in laboratory medicine. The International Federation of Clinical Chemistry and Laboratory Medicine (IFCC), through its Working Group on Lipoprotein(a) and together with research institutions and several diagnostic companies, have succeeded in developing an international reference material that is intended for the transfer of a lipoprotein(a) concentration to manufacturers' master calibrators. IFCC SRM 2B has recently been accepted by the WHO Expert Committee on Biological Standardization as the 'First WHO/IFCC International Reference Reagent for Lipoprotein(a) for Immunoassay'. The assigned unitage of 0.1071 nanomoles of lipoprotein(a) per vial is traceable to the consensus reference method for lipoprotein(a) and will enable conformity by diagnostic companies to the European Union's Directive on In vitro Diagnostic Medical Devices for the metrological traceability of calibrator materials.

    Interventions to prevent and detect bacterial contamination of platelet concentrates (PCs) have reduced, but not eliminated the sepsis risk. Standardized bacterial strains are needed to validate detection and pathogen reduction technologies in PCs. Following the establishment of the First International Reference Repository of Platelet Transfusion-Relevant Bacterial Reference Strains (the 'repository'), the World Health Organization (WHO) Expert Committee on Biological Standardisation (ECBS) endorsed further repository expansion. Sixteen bacterial strains, including the four repository strains, were distributed from the Paul-Ehrlich-Institut (PEI) to 14 laboratories in 10 countries for enumeration, identification and growth measurement on days 2, 4 and 7 after low spiking levels [10-25 colony-forming units (CFU)/PC bag]. Spore-forming (Bacillus cereusPEI-B-P-07-S, Bacillus thuringiensisPEI-B-P-57-S), Gram-negative (Enterobacter cloacaePEI-B-P-43, Morganella morganiiPEI-B-P-74, PEI-B-P-91, Proteus mirabilisPEI-B-P-55, Pseudomonas fluorescensPEI-B-P-77, Salmonella choleraesuisPEI-B-P-78, Serratia marcescensPEI-B-P-56) and Gram-positive (Staphylococcus aureusPEI-B-P-63, Streptococcus dysgalactiaePEI-B-P-71, Streptococcus bovisPEI-B-P-61) strains were evaluated. Bacterial viability was conserved after transport to the participating laboratories with one exception (M. morganiiPEI-B-P-74). All other strains showed moderate-to-excellent growth. Bacillus cereus, B. thuringiensis, E. coli, K. pneumoniae, P. fluorescens, S. marcescens, S. aureus and S. dysgalactiae grew to >10 6 CFU/ml by day 2. Enterobacter cloacae, P. mirabilis, S. epidermidis, S. bovis and S. pyogenes achieved >10 6 CFU/ml at day 4. Growth of S. choleraesuis was lower and highly variable. The WHO ECBS approved all bacterial strains (except M. morganiiPEI-B-P-74 and S. choleraesuisPEI-B-P-78) for repository enlargement. The strains were stable, suitable for spiking with low CFU numbers, and

    Student coaches undertake internships to develop practical skills and gain experience to improve employability prospects. The characteristics of the coaches who undertake these internships, their experiences and the nature of the work being performed are currently unknown. The purpose of this study was to report the characteristics of strength and conditioning (S&C) coaches who have undertaken internships and their experiences during their respective placements. A total of 113 men and 6 women completed an online survey. Placements generally lasted 6-12 months (66%), were unpaid (93%) and took place at professional teams (63%). All respondents had a standard of experience prior to commencement (82%); a higher-education degree (bachelor's degree 56%; master's degree 18%) and others were qualified S&C coaches (16%). Activities consisted largely of coaching (47%), data collection (22%) and equipment set-up (25%) but lacked provision of appropriate training. Mentors were allocated to interns; however, often developmental objectives were not discussed, meetings were rarely documented, and in some cases, no meetings took place. This study suggests that internships offer worthwhile experiences and assistance in skill development to progress in S&C. However, clearer guidelines are required to define the responsibilities of employers and interns, to maximise these experiential learning opportunities and avoid the exploitation of willing students.

    The International Reactor Physics Experiment Evaluation (IRPhE) Project aims to provide the nuclear community with qualified benchmark data sets by collecting reactor physics experimental data from nuclear facilities, worldwide. More specifically the objectives of the expert group are as follows: - maintaining an inventory of the experiments that have been carried out and documented; - archiving the primary documents and data released in computer-readable form; - promoting the use of the format and methods developed and seek to have them adopted as a standard. For those experiments where interest and priority is expressed by member countries or working parties and executive groups within the NEA provide guidance or co-ordination in: - compiling experiments into a standard international agreed format; - verifying the data, to the extent possible, by reviewing original and subsequently revised documentation, and by consulting with the experimenters or individuals who are familiar with the experimenters or the experimental facility; - analysing and interpreting the experiments with current state-of-the-art methods; - publishing electronically the benchmark evaluations. The expert group will: - identify gaps in data and provide guidance on priorities for future experiments; - involve the young generation (Masters and PhD students and young researchers) to find an effective way of transferring know-how in experimental techniques and analysis methods; - provide a tool for improved exploitation of completed experiments for Generation IV reactors; - coordinate closely its work with other NSC experimental work groups in particular the International Criticality Safety Benchmark Evaluation Project (ICSBEP), the Shielding Integral Benchmark Experiment Data Base (SINBAD) and others, e.g. knowledge preservation in fast reactors of the IAEA, the ANS Joint Benchmark Activities; - keep a close link with the working parties on scientific issues of reactor systems (WPRS), the expert

    Full Text Available The article examines the market of leasing relations in the UK, Germany, France, the USA. Comparative analysis of development of leasing in foreign countries has been carried out in order to use international experience of leasing relations in Ukraine at the present stage of development of state economy. In spite of prevalence of leasing in developed countries, this kind of relationship is still uncommon in the economic environment of Ukraine because of its novelty and lack of experience. Relevance of leasing development in Ukraine, including the formation of leasing market, primarily is caused by a significant proportion of obsolete equipment and low efficiency of its use. One of solutions to these problems can be leasing which brings together all the elements of international trade, credit, and investment operations.

    The rapid, selective, and sensitive determination of cyanide anion (CN{sup -}) using a simple paper strip is highly attractive because cyanide is acutely lethal to living organisms via all routes of administration, including alcohol consumption and inhaling cigarette smoke. Here, a synthetic probe (1) was designed for the selective determination of cyanide. The probe displays rapid and large blue spectral change (Δλ{sub abs}=148 nm, Δλ{sub em}= 165 nm) with respect to target recognition. Probe 1 exhibits a strong push-pull electronic effect and comprises a dimethylaminoaryl group as a donor and malononitrile as an acceptor; the π-conjugation system can be destroyed by the Michael-type addition of cyanide at the electrophilic β-positions of the nitrile groups, resulting in the marked emergence of a peak at λ{sub em}= 515 nm. The developed probe was successfully applied to a paper test strip because of its noticeable optical changes upon reaction with cyanide. The fabricated dumbbell-shaped paper strip with an internal reference allowed the cyanide detection, which is indispensable for quantitative analysis in point-of-care testing. The paper strip test showed selective response to cyanide, with a linear correlation in the range of 0-25 mM in a simple and cost-effective manner.

  19. An Internal Reference Control Duplex Real-Time Polymerase Chain Reaction Assay for Detecting Bacterial Contamination in Blood Products.

    Jin-Ju Zhang

    Full Text Available Real-time polymerase chain reaction (RT-PCR enables effective and sensitive screening for infectious risk in the field of blood safety. However, when using RT-PCR to detect bacterial contamination, several intractable points must be considered, one of which is the lack of appropriate quality control. In this study, we developed a simplified RT-PCR assay in which the same primer set and two distinct probes were used to detect both, an internal reference control and the target in a reaction. The copy number of the internal reference control represents the positive detection limit of the assay; therefore, when the threshold-cycle value of the target is less than or equal to that of the internal reference control, the result obtained for the target can be considered to be a true positive. When human gDNA was spiked with Escherichia coli gDNA and the detection limit for the internal reference control was set to five copies, the measured detection limit for E. coli gDNA was two copies. The internal reference control duplex RT-PCR assay showed high efficiency (0.91-1.02, high linearity (R2 > 0.99, and good reproducibility in intra- and inter-assay comparisons. Lastly, when human platelet-rich plasma samples were spiked with E. coli or other bacterial species, all species were detected efficiently, and the results of a two-sample pooled t test showed that the limit of detection for E. coli was 1 cfu/mL. Here, we present a synthetic internal reference control molecule and a new statistical method for improving the reliability of RT-PCR assays when screening for bacterial contamination in blood products.

    At present, there is an urgent need to preserve integral reactor physics experimental data including separate or special effects data for nuclear energy and technology applications and the knowledge and competence contained therein. The International Reactor Physics Evaluation Project (IRPhEP) was initiated as a pilot activity in 1999 by the Organization of Economic Cooperation and Development (OECD) Nuclear Energy Agency (NEA) Nuclear Science Committee (NSC). The project was endorsed as an official activity of the NSC in June of 2003. While coordination and administration of the IRPhEP takes place at an international level, each participating country is responsible for the administration, technical direction, and priorities of the project within their respective countries. This document outlines the general presentation guidelines that evaluators should follow for the description of the experiments and all relevant experimental data in order to ensure the consistency between the evaluations published in the final Handbook. Publication templates will be used to ensure this consistency and will follow the general scheme below: 1 - Experiment identification number; 2- Date; 3 - Name of experiment (Purpose of experiment, Phenomena measured and scope); 4 - Name or designation of experimental programme; 5 - Description of facility; 6 - Description of test or experiment (Experimental configuration, Core life cycle, Experimental limitations or shortcomings); 7 - Phenomena measured (Description of results and analysis, Special features and characteristics of experiment, Measurement systems/methods and uncertainties); 8 - Duplicate or complementary experiments / other related experiments; 9 - Status of completion of the evaluation; 10 - References (pointer to evaluation, archive if available, otherwise generic bibliographic reference); 11 - Authors/ organisers 12 - Material available

    For calculating color differences, the CIEDE2000 and CIE94 equations are widely used and recommended. These equations were derived more than a decade ago, based for a large part on the RIT-Dupont set of visual data. This data was collected from a series of psychophysical tests that use the method of constant stimuli. In this method, observers need to compare the color difference within a sample pair to that between a reference pair. In the current investigation, we show that the color difference equation significantly changes if reference pairs are chosen in the underlying visual experiments that differ from what was used when creating the RIT-Dupont dataset. The investigation is done using metallic paint samples representing two color centers, red and yellow-green. We show that the reproducibility differs for three different reference pairs, and that for modeling the visual data for the yellow-green color center, extra model terms are required as compared to the CIEDE2000 equation. Our results suggest that observers differ in their ability to mentally convert a color difference recognized in a sample pair into an equivalent color difference along the color difference direction represented by the reference pair. We also find that in these tests the tolerance to lightness differences is widened by a factor of 1.3 to 1.6, and that for the red color center the tolerance ellipsoid is rotated by 30° as compared to the CIEDE2000 equation. The latter observations are possibly due to the metallic texture in the samples used for the current experiment.

    The applicability of international risk scores in heart surgery (HS) is not well defined in centers outside of North America and Europe. To evaluate the capacity of the Parsonnet Bernstein 2000 (BP) and EuroSCORE (ES) in predicting in-hospital mortality (IHM) in patients undergoing HS at a reference hospital in Brazil and to identify risk predictors (RP). Retrospective cohort study of 1,065 patients, with 60.3% patients underwent coronary artery bypass grafting (CABG), 32.7%, valve surgery and 7.0%, CABG combined with valve surgery. Additive and logistic scores models, the area under the ROC (Receiver Operating Characteristic) curve (AUC) and the standardized mortality ratio (SMR) were calculated. Multivariate logistic regression was performed to identify the RP. Overall mortality was 7.8%. The baseline characteristics of the patients were significantly different in relation to BP and ES. AUCs of the logistic and additive BP were 0.72 (95% CI, from 0.66 to 0.78 p = 0.74), and of ES they were 0.73 (95% CI; 0.67 to 0.79 p = 0.80). The calculation of the SMR in BP was 1.59 (95% CI; 1.27 to 1.99) and in ES, 1.43 (95% CI; 1.14 to 1.79). Seven RP of IHM were identified: age, serum creatinine > 2.26 mg/dL, active endocarditis, systolic pulmonary arterial pressure > 60 mmHg, one or more previous HS, CABG combined with valve surgery and diabetes mellitus. Local scores, based on the real situation of local populations, must be developed for better assessment of risk in cardiac surgery.

    Internationally trained health professionals are an important part of the domestic workforce, but little is known about the working experiences of internationally trained pharmacists (ITPs) in Great Britain (GB). The purpose of this study is to explore the work experiences of ITPs practising in the community or hospital sector in GB. Twenty-five semi-structured, face-to-face interviews were conducted with a sample of European Economic Area (EEA) and non-EEA pharmacists who, at the time of the study, practised in the community (n = 20) or hospital sector (n = 5) in the North West England from March to May 2009. In general, ITPs complained about their heavy workload, long working hours and lack of support from their employers. Specifically, EEA pharmacists in most cases felt excluded from the professional network and sensed colleagues saw them as 'foreigners' while some non-EEA pharmacists had to deal with a level of hostility from patients. This novel research provides a foundation for future work on ITPs in GB and could assist employers to better target their efforts in development of standards to support the working experiences of ITPs in GB. © 2014 Royal Pharmaceutical Society.

    Full text: Introduction: Modern nuclear medicine (NM) metabolic therapy involves treatment with radionuclides sources mainly β-, and lately more often and α- rays and aims target specificity to the disease process with minimal damage to healthy surrounding tissues. Materials and Methods: We present some of the most important clinically significant contemporary trends in metabolic therapy in the light of international experience, including low-known in Bulgaria peptide radioreceptor therapy, radioimmunotherapy and so called SIRT (Selective internal radiation therapy) for liver metastases. Results: The ability of NM therapy range from definitive treatment of benign thyroid disease and differentiated thyroid cancer by achieving partial response or complete remission to a temporary palliative analgesic and symptom reducing effect in different, mainly cancer, diseases. Conclusion: The principle of 'terradiagnostic' - the interdependence of diagnostic and therapeutic nuclear medicine approaches is crucial for individualizing treatment and achieving better results in extending survival and improving the quality of life of patients

    International Living With a Star program is aimed at the creation of a global monitoring system allowing us to observe in a continuous way the Sun's activity and to follow its development and influence on numerous Earth structures - natural, industrial and especially human ones. Such an efficiently operating system has to include regular observations at every stage of the Sun-Earth interaction - from far space to the Earth's surface. The International Space Station (ISS) is well located as a long term ionospheric monitoring site. To this end, an international team headed by Space Research Institute of Russian Academy of Sciences agreed to create a system of space buoys and to install it onboard the Russian segment of ISS with the goal of studying the ISS environment (OBSTANOVKA in Russian). The "OBSTANOVKA-1" stage will be carried out first (launch in 2006) to provide a databank of electromagnetic fields and plasma-wave processes occurring in the ISS near-surface zone in order to study the plasma component features of near-Earth space. To achieve these goals the Plasma-Wave Complex (PWC) of scientific instrumentation will be created this year. The international cooperation (listed by the authors above) allows us not only to decrease the cost of instrumentation for every participating party but also to raise the scientific and technological level of the experiment. The main scientific premises of the OBSTANOVKA-1 experiment, realization schedule and a detailed description of PWC composition and measured parameters are given in this report.

    The literature on shielding experiment and calculation of high energy particles above 20 MeV has been surveyed. The survey covers thirteen journals, from 1965 up to 1989. For each paper, applicable information is listed on type and energy of the projectile, the accelerator used, composition and thickness of the target and shielding materials, shielding geometry, the experimental and calculational methods, and the quantities obtained. The references on shielding experiment and on shielding calculation are accessed through two indices which list the projectile-target and shielding material combination, shielding geometry and the projectile energy range. The literature on neutron, photon and hadron production from thick target bombarded by charged particles has been surveyed mainly from 1984 as a complement of the previous work. (author)

    For the past decade participation in service and experiential learning in higher education has increased. The purpose of this study was to explore the lived experience of BSN and MSN students participating in a multidisciplinary service-learning course in a rural, underserved village in Belize. Researchers analyzed student journals utilizing qualitative data analysis techniques. There were eight consistent themes found in the student journals. The findings indicate that international service learning opportunities increase students' awareness of their place in a global society and the potential contribution they can make in society. For the past decade, service and experiential learning in higher education, including nursing education, has become increasingly important. Simply put, service and experiential learning combine community service activities with a student's academic study for the sole purpose of enriching the academic experience. As faculty, we feel the goal of baccalaureate and graduate nursing education is to produce an educated professional who will become a responsible citizen.

    Fehr, Nils-Henrik von der; Harbord, David

    1998-09-01

    This publication gives a survey of economic theory and international experience connected to electricity spot markets. The main purpose is to consider the attempts that have been made to apply economic theory and empirical methods to the analysis of electricity markets, and to evaluate them in light of theoretical considerations and empirical evidence. The publication describes in simple terms the basic pool pricing mechanism, and experience with pools in a number of countries. It is worth emphasizing that it is not the purpose to treat in extensive detail the structure of electricity pools around the world. Key factors of the markets in England and Wales, Norway and Australia are described in order to allow for a comparison of design issues and evaluation of competitive performance. 80 refs., 14 figs., 15 tabs.

    2012-06-01

    The purpose of this study was to investigate the perspectives of occupational therapy students who have engaged in international, cross-cultural learning and service experiences. This study utilized a qualitative, phenomenological design. Nine semi-structured interviews were conducted with students who engaged in international learning opportunities. The interviews were coded and analyzed using a constant comparative analysis approach. Three central themes emerged from the data analysis. Connectedness is the process of forming relationships with others while engaging in cross-cultural experiences. Students formed relationships with faculty, other students, and people within the community. Cultural awareness is the recognition and understanding of a different culture and responding to those differences. Students attempted to understand the new culture in comparison to their own lived experiences. Complexity portrays cross-cultural opportunities as dynamic, multi-faceted and intricate. This was demonstrated as the students raised additional questions about the conflict between their own culture and the new culture they entered. Students also identified limited orientation, support and structure with such experiences and the conflicting roles between volunteer, student, and team member. The ability to connect with others when building relationships in diverse cultural contexts held meaning for the students; however, the students also expressed conflict in trying to make sense of the new culture as it often challenged personal beliefs and constructs. The complexity and challenges of engaging in these opportunities needs to be recognized and further explored to assess how curricula and faculty best supports culturally responsive care. © 2011 The Authors Australian Occupational Therapy Journal © 2011 Occupational Therapy Australia.

    The Compressed Baryonic Matter (CBM) experiment is a part of the Facility for Antiproton and Ion Research (FAIR) in Darmstadt at GSI. In CBM experiment a precisely time synchronized fault tolerant self-triggered electronics is required for Data Acquisition (DAQ) system in CBM experiments which can support high data rate (up to several TB/s). As a part of the implementation of the DAQ system of Muon Chamber (MUCH) which is one of the important detectors in CBM experiment, a FPGA based Gigabit Transceiver (GBTx) emulator is implemented. Readout chain for MUCH consists of XYTER chips (Front end electronics) which will be directly connected to detector, GBTx emulator, Data Processing Board (DPB) and First level event selector board (FLIB) with backend software interface. GBTx emulator will be connected with the XYTER emulator through LVDS (Low Voltage Differential Signalling) line in the front end and in the back end it is connected with DPB through 4.8 Gbps optical link. IPBus over Ethernet is used for internal monitoring of the registers within the GBTx. In IPbus implementation User Datagram Protocol (UDP) stack is used in transport layer of OSI model so that GBTx can be controlled remotely. A Python script is used at computer side to drive IPbus controller.

  17. Robust RT-qPCR data normalization: validation and selection of internal reference genes during post-experimental data analysis.

    Full Text Available Reverse transcription and real-time PCR (RT-qPCR has been widely used for rapid quantification of relative gene expression. To offset technical confounding variations, stably-expressed internal reference genes are measured simultaneously along with target genes for data normalization. Statistic methods have been developed for reference validation; however normalization of RT-qPCR data still remains arbitrary due to pre-experimental determination of particular reference genes. To establish a method for determination of the most stable normalizing factor (NF across samples for robust data normalization, we measured the expression of 20 candidate reference genes and 7 target genes in 15 Drosophila head cDNA samples using RT-qPCR. The 20 reference genes exhibit sample-specific variation in their expression stability. Unexpectedly the NF variation across samples does not exhibit a continuous decrease with pairwise inclusion of more reference genes, suggesting that either too few or too many reference genes may detriment the robustness of data normalization. The optimal number of reference genes predicted by the minimal and most stable NF variation differs greatly from 1 to more than 10 based on particular sample sets. We also found that GstD1, InR and Hsp70 expression exhibits an age-dependent increase in fly heads; however their relative expression levels are significantly affected by NF using different numbers of reference genes. Due to highly dependent on actual data, RT-qPCR reference genes thus have to be validated and selected at post-experimental data analysis stage rather than by pre-experimental determination.

    2013-11-01

    Short-term, study-abroad, elective engineering courses were developed in order to raise the international awareness and global competency of engineering students. These Compact International Experience (CIE) courses were taught in response to a strong student desire for engineering study abroad courses and an effort by the home institution to internationalize its curriculum. An assessment of repeat offerings of two three-semester-unit courses on Topics in Fluid Mechanics and Advanced Electronic Circuit Design in a three-week time frame in France and Australia was performed. The goals of the two CIE courses are an effective teaching of their respective technical content as well as a student understanding of the cultural environment and the impact of engineering solutions from a global and societal viewpoint. In the repeat offerings, increased interaction with local industry was an additional goal. The CIE courses were assessed through surveys completed at the beginning and end of the courses, weekly student reflection papers, course evaluations, and formalized instructor observations. Based on the assessment performed, the two CIE courses have been found to be a valuable approach in the delivery of engineering technical electives combined with an international experience.

  20. The International Experience of Regional Development of Creative Industries

    2017-12-01

    Full Text Available The article is aimed at generalizing the international experience of regional development of creative industries and defining directions of its implementation in Ukraine. The experience of the world countries on regional development of creative industries has been generalized, tendencies and specificity of these development processes have been identified. The interrelation of the process of development of creative industries with innovation development of regions has been defined. Prospects for development of creative industries in regions of Ukraine have been identified and directions of implementation of foreign experience have been suggested. Thus, strategic measures for the development of creative clusters can be the corresponding priorities of cultural policy in the regions, the development of specific projects and programs, the opening of art-incubators, the creation of a favorable investment climate, financial and tax incentives as conditions for interaction between creativity and business. The scale and dynamics of the world’s creative sector, which has a significant potential for growth and less vulnerability in financial-economic crises compared to the traditional sector, gives chance to high expectations for the development of creative industries in Ukraine as well.

    In the conventional travel behavior models such as logit and probit, decision makers are assumed to conduct the absolute evaluations on the attributes of the choice alternatives. On the other hand, many researchers in cognitive psychology and marketing science have been suggesting that the perceptions of attributes are characterized by the benchmark called “reference points” and the relative evaluations based on them are often employed in various choice situations. Therefore, this study developed a travel behavior model based on the mental accounting theory in which the internal reference points are explicitly considered. A questionnaire survey about the shopping trip to the CBD in Matsuyama city was conducted, and then the roles of reference points in travel mode choice contexts were investigated. The result showed that the goodness-of-fit of the developed model was higher than that of the conventional model, indicating that the internal reference points might play the major roles in the choice of travel mode. Also shown was that the respondents seem to utilize various reference points: some tend to adopt the lowest fuel price they have experienced, others employ fare price they feel in perceptions of the travel cost.

    Background Several distributions of country-specific blood pressure (BP) percentiles by sex, age and height for children and adolescents have been established worldwide. However, there are no globally unified BP references for defining elevated BP in children and adolescents, which limit international comparisons of prevalence of pediatric elevated BP. We aimed to establish international BP references for children and adolescents using seven nationally representative data (China, India, Iran, Korea, Poland, Tunisia and USA). Methods and Results Data on BP for 52,636 non-overweight children and adolescents aged 6–19 years were obtained from seven large nationally representative cross-sectional surveys in China, India, Iran, Korea, Poland, Tunisia, and USA. BP values were obtained with certified mercury sphygmomanometers in all seven countries, using standard procedures for BP measurement. Smoothed BP percentiles (50th, 90th, 95th and 99th) by age and height were estimated using the Generalized Additive Model for Location Scale and Shape (GAMLSS) model. BP values were similar between males and females until the age of 13 years and were higher in males than females thereafter. Compared to BP level of the 90th and 95th percentiles of the U.S. Fourth Report at median height, systolic BP of the corresponding percentiles of these international references was lower while diastolic BP was similar. Conclusions These international BP references will be a useful tool for international comparison of the prevalence of elevated BP in children and adolescents and may help identify hypertensive youths in diverse populations.

    Full Text Available The Biological Weapons Convention (BWC does not explicitly refer to sustainable development despite the fact that other United Nations (UN disarmament documents prescribe that international environmental law principles and sustainable development be considered among arms control agreements. This study’s objective is to utilize the principle of integration’s three components of environmental, economic, and social development, as found in the International Sustainable Development Law (ISDL from the New Delhi Declaration (Delhi Declaration of Principles of International Law Relating to Sustainable Development, in order to evaluate whether the BWC contains such components; thereby, making it possible for the BWC to contribute to sustainable development. The methodology of this study is necessarily qualitative, given that it is a socio-legal research that relies on international agreements such as the BWC, declarations, resolutions, plans of implementation, other non-binding documents of the UN, and secondary resources—all of which are analyzed through a document analysis. The results show that the BWC addresses the environment (Article II, prohibits transfers relating to export controls, international trade, and economic development (Article III, while at the same time, covering social development concerns, health, and diseases that make up the international social law (Article X. Since the BWC is found to be capable of contributing to sustainable development, it is concluded that ISDL cannot be restricted to international environmental, economic, and social law, but should be expanded to include international arms control law.

    LISA is a proposed space-based laser interferometer detecting gravitational waves by measuring distances between free-floating test masses housed in three satellites in a triangular constellation with laser links in-between. Each satellite contains two optical benches that are articulated by moving optical subassemblies for compensating the breathing angle in the constellation. The phase reference distribution system, also known as backlink, forms an optical bi-directional path between the intra-satellite benches. In this work we discuss phase reference implementations with a target non-reciprocity of at most 2π μrad \\sqrtHz-1 , equivalent to 1 pm \\sqrtHz-1 for a wavelength of 1064 nm in the frequency band from 0.1 mHz to 1 Hz. One phase reference uses a steered free beam connection, the other one a fiber together with additional laser frequencies. The noise characteristics of these implementations will be compared in a single interferometric set-up with a previously successfully tested direct fiber connection. We show the design of this interferometer created by optical simulations including ghost beam analysis, component alignment and noise estimation. First experimental results of a free beam laser link between two optical set-ups that are co-rotating by  ±1° are presented. This experiment demonstrates sufficient thermal stability during rotation of less than 10‑4 K \\sqrtHz-1 at 1 mHz and operation of the free beam steering mirror control over more than 1 week.

    The environment provides both a source of goods and services and a 'sink' for residues of the production and consumption processes. This is not reflected into conventional estimate of GDP (gross domestic product), the most commonly used measure of aggregate income. The purpose of this paper is to explore whether environmentally-adjusted national income measure can be derived. In the first part, the authors discuss both the shortcomings of the current national income measures, with reference to environmental and natural resources, and the debate on this issues; then they analyse the existing experiences to provide environmentally-adjusted indicators of national accounts. In the second part, the authors present an evaluation of the costs of environmental degradation in Italy in the period 1988-1990, based on the methodologies adopted in a pilot study carried out by UNSO (United Nations Statistical Office) and the World Bank for Mexico

    The triumph of 20th century particle physics was the development of the Standard Model and the confirmation of many of its aspects. Experiments determined the particle constituents of ordinary matter, and identified four forces that hold matter together and transform it from one form to another. Particle interactions were found to obey precise laws of relativity and quantum theory. Remarkable features of quantum physics were observed, including the real effects of 'virtual' particles on the visible world. Building on this success, particle physicists are now able to address questions that are even more fundamental, and explore some of the deepest mysteries in science. The scope of these questions is illustrated by this summary from the report Quantum Universe: (1) Are there undiscovered principles of nature; (2) How can we solve the mystery of dark energy; (3) Are there extra dimensions of space; (4) Do all the forces become one; (5) Why are there so many particles; (6) What is dark matter? How can we make it in the laboratory; (7) What are neutrinos telling us; (8) How did the universe begin; and (9) What happened to the antimatter? A worldwide program of particle physics investigations, using multiple approaches, is already underway to explore this compelling scientific landscape. As emphasized in many scientific studies, the International Linear Collider is expected to play a central role in what is likely to be an era of revolutionary advances. Discoveries from the ILC could have breakthrough impact on many of these fundamental questions. Many of the scientific opportunities for the ILC involve the Higgs particle and related new phenomena at Terascale energies. The Standard Model boldly hypothesizes a new form of Terascale energy, called the Higgs field, that permeates the entire universe. Elementary particles acquire mass by interacting with this field. The Higgs field also breaks a fundamental electroweak force into two forces, the electromagnetic

    Full text: In 2008 the University of Groningen has ten years of experience with the system of complex broad licences. This system was introduced on a larger scale in the Netherlands in the last decade of the twentieth century. Its main characteristics are an internal radiation protection organization and a system of internal permits or licences for all applications of ionizing radiation along with periodical inspections. Since 1998/9 we yearly conduct inspections of all users of ionizing radiation within the University of Groningen. In our presentation we will discuss the general scheme for these inspections as well as the development of its results over the past decade. Following a period of habituation the last few years show a adequate and continuous level of radiation protection. It is also concluded that continuation of the inspection projects is a prerequisite to preserve this situation. Combined with the inspection project of 2007 an informal study of the 'customer'-satisfaction with respect to various aspects of the radiation protection organization was performed. Our data were collected using a questionnaire filled out by local radiation safety officers. In this contribution detailed results of this investigation will be presented.

    Bond, Gary; Carter, Laurence

    1995-01-01

    This paper provides an overview of the recent trend towards private ownership and financing of power projects in the developing countries, focusing on the role played by both private and public agencies in meeting the large financing challenges. The paper draws upon the operational experience of the International Finance Corporation, which has been involved in the financing of more than 30 private power projects in the developing countries over the past three decades. Among the issues that affect implementation of private power projects is the balancing of risk and reward to equity investors and to commercial lenders. The paper discusses the principal sources of risk and the strategies used to manage them. A related issue is the competition for capital on the international markets, and the techniques that are being devised to bring more finance to the power sector. Finally, the paper considers the role of government in bringing private investors to the power sector, and the approaches being adopted to balance the needs of investors with the needs of the public.

    Nursing leaders from six countries engaged in a year-long discussion on global leadership development. The purpose of these dialogues was to strengthen individual and collective capacity as nursing leaders in a global society. Field experiences in practice and education were shared. Perspectives on global leadership can strengthen nurses' contributions to practice, workplace and policy issues worldwide. Transformational leadership empowers nurses' increasing confidence. Mentoring is needed to stimulate leadership development but this is lacking in many settings where nurses practice, teach and influence policy. Organizations with global mission provide opportunity for nurses' professional growth in leadership through international dialogues. Dialogues among participants were held monthly by conference calls or videoconferences. Example stories from each participant illustrated nursing leadership in action. From these exemplars, concepts were chosen to create a framework. Emerging perspectives and leadership themes represented all contexts of practice, education, research and policy. The cultural context of each country was reflected in the examples. Themes emerged that crossed global regions and countries. Themes were creativity, change, collaboration, community, context and courage. Relationships initially formed in professional organizations can be extended to intentionally facilitate global nursing leadership development. Exemplars from the dialogues demonstrated nursing leadership in health policy development within each cultural context. Recommendations are given for infrastructure development in organizations to enhance future collaborations. © 2014 International Council of Nurses.

    Microgrids can provide an avenue for increasing the amount of distributed generation and delivery of electricity, where control is more dispersed and quality of service is locally tailored to end-use requirements. Much of this functionality is very different from the predominant utility model to date of centralized power production which is then transmitted and distributed across long distances with a uniform quality of service. This different functionality holds much promise for positive change, in terms of increasing reliability, energy efficiency, and renewable energy while decreasing and carbon emissions. All of these functions should provide direct cost savings for customers and utilities as well as positive externalities for society. As we have seen from the international experience, allowing microgrids to function in parallel with the grid requires some changes in electricity governance and incentives to capture cost savings and actively price in positive externalities. If China can manage to implement these governance changes and create those incentive policies, it will go beyond the establishment of a successful microgrid demonstration program and become an international leader in microgrid deployment.

    Green, M.A.; Rey, J.M.

    2002-01-01

    The international muon ionization cooling experiment MICE will consist of two focusing cooling cells and a pair of uniform field solenoids used for particle identification and emittance measurements. The 2.75-meter long cooling cells have a pair of field flip coils and a coupling coil. The 0.52-meter diameter field flip coils surround an absorber that removes transverse and longitudinal momentum from the muons to be cooled. The beam in the absorber is at a minimum beta point so that scattering of the muons is minimized. The 1.7-meter diameter coupling coils are outside of conventional 201.25 MHz RF cavities that accelerate the muons putting longitudinal momentum into the muons without putting back the transverse momentum into the beam. A third set of flip coils helps the muon beam transition from and to the experimental solenoids. The 0.6-meter diameter experimental solenoids have a uniform field region (good to about 1 part in 1000) that is 1.3-meters long. The MICE experiment magnets must operate as a single unit so that the field profile will produce the maximum muon cooling

    2017-01-01

    Abstract Interest in nephrology careers continues to remain low in the USA. Educational innovations that enhance interest in nephrology among medical trainees are being actively studied. While internal medicine (IM) residency programs commonly offer the inpatient nephrology elective to the resident, outpatient nephrology experience is lacking. Understanding the provision of care in outpatient and home dialysis and management of patients with glomerular diseases, chronic kidney disease and kidney transplantation are vital components of an outpatient nephrology rotation. In this review article, we share our experiences in incorporating outpatient nephrology to the IM resident’s elective time. We also present the structure of the nephrology rotations at our programs and suggest several learning opportunities in outpatient nephrology that the training community can provide to medical residents. Strategies to effectively set up an outpatient nephrology rotation are also described. While more educational research on the impact of outpatient nephrology on resident learning and career choices are needed, we encourage a collaborative effort between faculty members in nephrology and the medicine residency programs to provide this unique learning opportunity to IM residents.

  19. Virtual Reality Simulation of the International Space Welding Experiment

    Phillips, James A.

    1996-01-01

    Virtual Reality (VR) is a set of breakthrough technologies that allow a human being to enter and fully experience a 3-dimensional, computer simulated environment. A true virtual reality experience meets three criteria: (1) It involves 3-dimensional computer graphics; (2) It includes real-time feedback and response to user actions; and (3) It must provide a sense of immersion. Good examples of a virtual reality simulator are the flight simulators used by all branches of the military to train pilots for combat in high performance jet fighters. The fidelity of such simulators is extremely high -- but so is the price tag, typically millions of dollars. Virtual reality teaching and training methods are manifestly effective, and we have therefore implemented a VR trainer for the International Space Welding Experiment. My role in the development of the ISWE trainer consisted of the following: (1) created texture-mapped models of the ISWE's rotating sample drum, technology block, tool stowage assembly, sliding foot restraint, and control panel; (2) developed C code for control panel button selection and rotation of the sample drum; (3) In collaboration with Tim Clark (Antares Virtual Reality Systems), developed a serial interface box for the PC and the SGI Indigo so that external control devices, similar to ones actually used on the ISWE, could be used to control virtual objects in the ISWE simulation; (4) In collaboration with Peter Wang (SFFP) and Mark Blasingame (Boeing), established the interference characteristics of the VIM 1000 head-mounted-display and tested software filters to correct the problem; (5) In collaboration with Peter Wang and Mark Blasingame, established software and procedures for interfacing the VPL DataGlove and the Polhemus 6DOF position sensors to the SGI Indigo serial ports. The majority of the ISWE modeling effort was conducted on a PC-based VR Workstation, described below.

    Full Text Available Atypical respiratory sinus arrhythmia (RSA, a biomarker of emotion dysregulation, is associated with both externalizing and internalizing behaviors. In addition, social adversity and gender may moderate this association. In this study, we investigated if RSA (both resting RSA and RSA reactivity in an emotion regulation task predicts externalizing and/or internalizing behaviors and the extent to which social adversity moderates this relationship. Two hundred and fifty-three children (at Time 1, mean age = 9.05, SD = 0.60, 48% boys and their caregivers from the community participated in this study. Resting RSA and RSA reactivity were assessed, and caregivers reported children’s externalizing and internalizing behaviors at both Time 1 and Time 2 (1 year later. We found that lower resting RSA (but not RSA reactivity at Time 1 was associated with increased externalizing and internalizing behaviors at Time 2 in boys, even after controlling for the effects of Time 1 behavioral problems and Time 2 age. Moreover, there was a significant interaction effect between Time 1 resting RSA and social adversity such that lower resting RSA predicted higher externalizing and internalizing behaviors in boys only under conditions of high social adversity. Follow-up analyses revealed that these predictive effects were stronger for externalizing behavior than for internalizing behavior. No significant effects were found for girls. Our findings provide further evidence that low resting RSA may be a transdiagnostic biomarker of emotion dysregulation and a predisposing risk factor for both types of behavior problems, in particular for boys who grow up in adverse environments. We conclude that biosocial interaction effects and gender differences should be considered when examining the etiological mechanisms of child psychopathology.

    The measurement of insulin-like growth factors (IGF-I) and insulin-like growth factor-binding protein (IGFBP-3) often serves as first-line testing in children with growth disorders. The role of acid-labile subunit (ALS) as a screening parameter for homozygous or heterozygous mutations of the ALS gene still has to be determined. IGF-I, IGFBP-3, and ALS were measured in 252 samples from children and adolescents. Reference curves were fitted using generalized additive model for location, scale and shape (GAMLSS) models and SD-Scores were calculated. Bootstrap analysis was used to quantify the uncertainty of the estimated percentiles. Bland-Altman plots were used to investigate the discrepancy between our newly estimated standard deviation scores (SDS) and SDS calculated on the basis of previous reference data. We present reference data for enzyme-linked immunosorbent assay (ELISA) measurements based on recommended internal standard for IGF-I, IGFBP-3, and ALS suitable for calculation of SD-scores. The Bland-Altman plot shows a rough agreement between the previous SDS calculation and our new one only for SDS around 1; for SDS at -2, an average difference of 0.83 SD was noticed. Our IGF-I reference values for the interval of interest in diagnosing growth hormone deficiency (GHD) (prepubertal age) are solid as proved by bootstrap analysis. The difference in calculated SD scores by using data provided previously highlights the importance of using labor and method specific reference data.

    2012-01-01

    The illegal transport of conventional explosives and biological material has been observed in public mail and could lead to serious health hazards. In response to Member States' requests to establish guidance for detecting the movement of radioactive material in international mail, the IAEA and the Universal Postal Union (UPU) undertook a joint effort to prepare this publication. It considers how radioactive materials in international mail might be detected, how best to monitor for these materials in mail facilities and how to respond appropriately. This publication brings together a concise but comprehensive description of the various techniques and equipment used to detect and control radioactive material during mail processing.

    With the aim of exchanging information on various subjects about radiation protection and designing a site where the members can send and receive information on courses, scientific activities, articles, technical opinions, commentaries and everything that promotes the communication, collaboration and integration, the 15th March 2002 the networking: 'radioproteccion' is created with 11 persons from 11 countries. The number of members had been increased. By the first month it had 117 members and by the end of the year 2002 it had already 179 members, 315 messages were send by then. By December 2007, there were 726 members from 28 countries mainly from Latin America: Argentina, Brazil, Bolivia, Chile, Colombia, Costa Rica, Cuba, Dominican Republic, Ecuador, Guatemala, Honduras, Mexico, Nicaragua, Panama, Paraguay, Peru, Uruguay and Venezuela. There were also members from Austria, Canada, France, Israel, Italy, Portugal, Spain, Sweden, United Kingdom and United States. There have been distributed 2049 messages about Congress, courses and activities on national and international radiation protection and related issues which initially were in Latin American and the Caribbean. This has allowed diverse specialists that work in different themes to interchange experiences and information about subjects of common interest. This objective is the continuation of the spreading of activities that since 1991 and for 10 consecutive years had been made through the Bulletin 'Proteccion Radiologica', from which 65000 samples were published and distributed to specialists from 40 countries thanks to the support of the International Atomic Energy Agency (IAEA) and the Pan-American Health Organization (PAHO). This idea is complemented by the Web: www.radioproteccion.org. Interesting topics have been discussed in the network for example: Pregnancy and medical radiation, emergency response, occupational exposure, radiation protection responsibilities, lessons learned from accidental

    This paper summarizes the first results from isolated droplet combustion experiments performed on the International Space Station (ISS). The long durations of microgravity provided in the ISS enable the measurement of droplet and flame histories over an unprecedented range of conditions. The first experiments were with heptane and methanol as fuels, initial droplet droplet diameters between 1.5 and 5.0 m m, ambient oxygen mole fractions between 0.1 and 0.4, ambient pressures between 0.7 and 3.0 a t m and ambient environments containing oxygen and nitrogen diluted with both carbon dioxide and helium. The experiments show both radiative and diffusive extinction. For both fuels, the flames exhibited pre-extinction flame oscillations during radiative extinction with a frequency of approximately 1 H z. The results revealed that as the ambient oxygen mole fraction was reduced, the diffusive-extinction droplet diameter increased and the radiative-extinction droplet diameter decreased. In between these two limiting extinction conditions, quasi-steady combustion was observed. Another important measurement that is related to spacecraft fire safety is the limiting oxygen index (LOI), the oxygen concentration below which quasi-steady combustion cannot be supported. This is also the ambient oxygen mole fraction for which the radiative and diffusive extinction diameters become equal. For oxygen/nitrogen mixtures, the LOI is 0.12 and 0.15 for methanol and heptane, respectively. The LOI increases to approximately 0.14 (0.14 O 2/0.56 N 2/0.30 C O 2) and 0.17 (0.17 O 2/0.63 N 2/0.20 C O 2) for methanol and heptane, respectively, for ambient environments that simulated dispersing an inert-gas suppressant (carbon dioxide) into a nominally air (1.0 a t m) ambient environment. The LOI is approximately 0.14 and 0.15 for methanol and heptane, respectively, when helium is dispersed into air at 1 atm. The experiments also showed unique burning behavior for large heptane droplets. After the

    The expanding number and increasing utility of clinical genetic tests is creating a growing burden on the Canadian healthcare system. Administrators are faced with the challenge of determining which genetic tests should be publicly funded. A discrete choice experiment (DCE) was utilized to assess the importance stakeholders place on five attributes of a genetic test. One hundred ninety individuals completed the DCE questions. Analysis of the data revealed that medical benefit of a test had the greatest impact on a respondent's decision to select a test for funding. The detection rate of the test ranked second in importance followed by severity of the condition, aim of the test, and cost. With limited resources available for referred out molecular genetic testing within a public healthcare setting such as Canada's, funding guidelines are critical. Our findings provide further evidence for the value of a decision-making framework and the relative importance of specific test attributes within such a framework. © 2015 John Wiley & Sons A/S.

    The Flight Dynamics Division (FDD) of the National Aeronautics and Space Administration (NASA) Goddard Space Flight Center (GFSC) provides extensive support and products for Space Shuttle missions, expendable launch vehicle launches, and routine on-orbit operations for a variety of spacecraft. A major challenge in providing support for these missions is defining and generating the products required for mission support and developing the method by which these products are exchanged between supporting agencies. As interagency and international cooperation has increased in the space community, the FDD customer base has grown and with it the number and variety of external interfaces and product definitions. Currently, the FDD has working interfaces with the NASA Space and Ground Networks, the Johnson Space Center, the White Sands Complex, the Jet propulsion Laboratory (including the Deep Space Network), the United States Air Force, the Centre National d'Etudes Spatiales, the German Spaceflight Operations Center, the European Space Agency, and the National Space Development Agency of Japan. With the increasing spectrum of possible data product definitions and delivery methods, the FDD is using its extensive interagency experience to improve its support of established customers and to provide leadership in adapting/developing new interfaces. This paper describes the evolution of the interfaces between the FDD and its customers, discusses many of the joint activities ith these customers, and summarizes key lessons learned that can be applied to current and future support.

    Experiments showed that by using combined targets, comprising a monitor aluminium foil and the substance examined, in the internal beam of a proton synchrotron, one can determine the number of particles that had passed through the target by the induced activity of 24 Na in aluminium. A combined target consisting of three aluminium foils (2.3 m.g./sq.cm) and a foil of the test substance (30-170 mg/sq.cm) was used. Monitoring was performed by the activity of the middle aluminium foil. Subsequent to respective measurements, the foils were extracted from the accelerator chamber and aged for 12-16 hr to cause decay of short-lived activities. The foil γ-ray spectrum was then recorded by means of a coaxial Ge-Li detector (40 cc, 8 keV). Results of control measurements were cited. The method ensured relatively accurate measurements (ca. 2%) of the dependence of cross-sections of the atomic number of the target nucleus

    test the dynamics and energetics of the numerical model, but also to advance the analysis based on combined wavelet and empirical orthogonal function. In particular, we focus on the study of the transient regime of internal wave generation near the ridge. Our analyses of the experimental fields show that, for fixed background stratification and topography, the evolution of the stratification anomaly strongly depends on the forcing frequency. The duration of the transient regime, as well as the amplitude reached in the stationary state vary significantly with the parameter ω/N (where ω is the forcing frequency, and N is the background Brunt-Väisälä frequency). We also observe that, for particular forcing frequencies, for which the ridge slope matches the critical slope of the first harmonic mode, internal waves are excited both at the fundamental and the first harmonic frequency. Associated energy transfers are finally evaluated both experimentally and numerically, enabling us to highlight the similarities and discrepancies between the laboratory experiments and the numerical simulations.

  12. Review of International Experience with Renewable Energy Obligation Support Mechanisms

    2005-06-01

    The main policy instruments currently used in the EU Member States to achieve the targets set for electricity produced from renewable energy sources are: (1) the quota obligation system; (2) the feed-in tariff system; and (3) the tendering system. The current study aims to review the experience gained with the quota obligation system. The report provides an overview of the regions where obligation systems have been implemented and contains a detailed evaluation of the performance of the obligation systems in the USA, the UK and in Sweden. The obligation systems in these countries have been evaluated based on the following criteria: Effectiveness; Market efficiency; Certainty for the renewable energy industry; Cost effectiveness; Stakeholder support for the obligation system; and Equity. The evaluation of international experiences with the obligation system gives rise to a mixed picture. Although an obligation in theory is effective and cost effective, it seems too early to conclude that the system delivers these promises in practice. On the one hand this is due to the limited period of implementation that makes it hard to distinguish between the direct effect of the system and some teething problems that will be solved in due time. On the other hand, the conclusion can be drawn that the obligation is a complex system, which will only function well if designed carefully. It does seem worthwhile, however, to continue monitoring the experiences with the obligation system abroad, because this will further reveal whether the system is indeed effective and cost effective in practice. In the longer term, e.g. beyond 2010, the introduction of an obligation system in the Netherlands could be considered. Finally, as the design of support schemes is being improved, it appears that the basic concepts of both the obligation system and the feed in system have been refined in such a way that the two systems are gradually converging. An important difference between the two systems

    To investigate and analyze the epidemiological profile of penile cancer in the state of Pernambuco and compare this information with other studies related to the issue. We conducted a retrospective, observational and descriptive study of all patients with penile cancer in two reference centers in Pernambuco - Brazil, from 2007 to 2012. The variables studied were: age, region from the state, socio-economic situation, previous postectomy, smoking, time from the beginning of injury to diagnosis, staging of the primary lesion, tumor differentiation, treatment performed and death due to cancer. The total number of patients was 88. The highest prevalence was seen in those aged between 66 and 75 years. About the socio-economic situation, 67% worked informally and 64.8% received up to two minimum wages. Of all patients, 57% were married and 50% illiterate. The Metropolitan Region of Recife was the one with the highest number of cases, 41%. Tobacco smoking was reported in 48.9% of cases and prior postectomy in 3.4%. Most often it was observed an average period of six months from the onset of symptoms to diagnosis. And when the lesion was diagnosed, it usually had 2 to 5 cm (64.7%), stage T2 in 50% and well differentiated in 79.6%. Partial penectomy was performed in 76.1% and total in 17%. Death was observed in 27.3%. The clinical profile and epidemiological characteristics found in this study are similar to other national and international studies related to the issue, i.e., typical of underdeveloped or developing countries.

    Two melodiotherapeutical principles, namely, the isoprinciple and the intermediary principle (Benenzon), are described in the light of results of recent investigations into the communicative function of music (Reinecke). The paper also discusses the difference between methods of musicotherapy used in the treatment of mental disorders in children and adults. Finally, international trends are analyzed and conclusions drawn in respect of the development of a standard methodology of melodiotherapy.

  19. An overview of international institutional mechanisms for environmental management with reference to Arctic pollution

    Evidence is mounting of the environmental impact in the Far North of economic and industrial activity elsewhere in the world. While the sources of pollutants found in the Arctic are many and widespread, it is up to just a few countries - notably Canada, the former Soviet Union, Finland, Norway and Greenland - to assess the damage and deal with the impacts. This paper discusses the issue of Arctic pollution in the context of trends in world economic growth, globalization of economic activity, international trade and related institutional arrangements (such as trade and environmental agreements). The importance of tracing the sources of particular contaminants is stressed; this is a first step towards internalization of environmental costs of production, and is also politically a key in efforts to control emissions. Trade and investment agreements commonly discuss rules for cross-border flows of goods, services, personnel and investment capital, as well as matters specific to particular economic sectors. Cross-border flows of pollutants and other 'bads' also merit detailed sectoral attention. This linkage would make explicit the connections between production and pollution (making possible the 'polluter pays' approach), and also widen the scope for redistribution of economic resources to equilibrate the situation (via trade and investment measures, among others) if flows of goods are related directly to flows of 'bads'. The paper examines the outlook for addressing Arctic pollution via international environmental agreements (along the lines of the Basel Convention, the Montreal Protocol, CITES, etc.), existing and future trade agreements (such as GATT), or new institutional approaches

  20. Clearing and dissecting insects for internal skeletal morphological research with particular reference to bees

    Full Text Available ABSTRACT A detailed protocol for chemical clearing of bee specimens is presented. Dry specimens as well as those preserved in liquid media can be cleared using this protocol. The procedure consists of a combined use of alkaline solution (KOH or NaOH and hydrogen peroxide (H2O2, followed by the boiling of the cleared specimens in 60–70% EtOH. Clearing is particularly useful for internal skeletal morphological research. This procedure allows for efficient study of internal projections of the exoskeleton (e.g., apodemes, furcae, phragmata, tentoria, internal ridges and sulci, but this process makes external features of the integument, as some sutures and sulci, readily available for observation as well. Upon completion of the chemical clearing process the specimens can be stored in glycerin. This procedure was developed and evaluated for the preparation of bees and other Apoidea, but modifications for use with other insect taxa should be straightforward after some experimentation on variations of timing of steps, concentration of solutions, temperatures, and the necessity of a given step. Comments on the long-term storage, morphological examination, and photodocumentation of cleared specimens are also provided.

    In 2014, the Swedish Association of Clinical Physiology recommended the use of a new reference material for exercise capacity in bicycle exercise stress testing, 'the Kalmar material'. Compared to the formerly used reference material, 'the Kristianstad material', an increase in the amount of patients being classified as having decreased exercise capacity was expected, but the extent of this in clinical practice is not known. Results of exercise capacity from 1449 bicycle exercise tests, in patients aged ≥20 years (656 women, 793 men) performed at two departments of Clinical Physiology before and after change of reference materials, were collected. Maximal workload was related to the predicted values of both reference materials. If made, recommendations for supplemental nuclear myocardial perfusion imaging study by the attending physician were noted. Using the new reference material, 31% of all patients were classified as having a decreased exercise capacity, compared to 17% using the formerly used reference material. The difference between the two reference materials was largest in the older age groups. In one of the departments, an increase in recommendations of supplemental myocardial perfusion studies was seen after introduction of the new reference material, whereas the opposite was seen at the other department. A large amount of patients are being classified as having decreased exercise capacity and very few as having good exercise capacity using the new reference material for exercise capacity. © 2017 Scandinavian Society of Clinical Physiology and Nuclear Medicine.

    To summarize international experiences in promoting use of generics and to extract essence for China's reference. This is a commentary of two systematic reviews about policies to promote use of generics and its implications to China. Price, reimbursement, and generic substitution policies in European countries, and approaches in low and middle income countries in promoting market competition, appropriate intellectual property right protection strategy, and necessary demand side incentives, are all meaningful for China to contain soaring pharmaceutical expenditures, and to maintain the achievements and outcomes of the national health system reform. Effective promotion of generics use must be practice based on the real situation. Tailor-made and comprehensive measures are needed to address both demand and supply sides barriers before achieving tangible cost containment effect without unexpected side effects. © 2013 Wiley Publishing Asia Pty Ltd and Chinese Cochrane Center, West China Hospital of Sichuan University.

    An extensive database of analytical results from a recent biological matrix Reference Material Characterization Campaign permitted an intercomparison of the performances of various methods among each other and with 'true' best estimate concentration values established for these materials. Six different variants of neutron activation analysis (NAA) methods were employed including: instrumental neutron activation analysis, instrumental neutron activation analysis with acid digestion, neutron activation analysis with radiochemical separation, neutron capture prompt gamma activation analysis, epithermal instrumental neutron activation analysis, and neutron activation analysis with preconcentration. The precision and accuracy performance of NAA-based analytical methods are compared with three other major techniques, atomic absorption spectrometry (AAS), atomic emission spectrometry (AES) and mass spectrometry (MS) for 28 elements in 10 natural matrix materials.

Set out the important points predetermine orientation and specificity of manifestations of national interests – potential participants of the subsoil in the Arctic zone. On the basis of the illuminated materials were obtained the following conclusions: Signifi cant interest in the Arctic show today, not only the fi ve countries (Russia, USA, Canada, Norway, Denmark, who own Arctic territories, but also polar state (Iceland, Sweden, Finland, the European Union and Asia. As a consequence of that, it is expected that in the XXI century the Arctic region will be the focus of attention as an official Arctic 45, and a number of states whose territory is quite removed from it; For Russia, given the current, acute political conditions (sanctions, confrontation with the West, Ukrainian crisis and war in the Middle East development of Arctic territories, some moved away, moved on tomorrow and the day after tomorrow on the agenda. This approach is fundamentally fl awed and fraught with a number of threats, because other countries do not decrease, but only increase their interest in this issue; Territorial opposition to all those involved in the topic of causing instability in the Arctic region, but does not represent a real threat for the emergence of large-scale conflict. Therefore, making the choice between the hard pressure of national interests and the interests of harmonization of the Arctic states, Russia must be based on international cooperationand mutual consideration of interests in the development of its Arctic strategy; Considering the cooperation of the countries of the Arctic Council and their cooperation in the framework of a global economic forum G8, there are prerequisites for the decision of the Arctic confl ict through negotiation and compromise.

    Background: In our modern world, the way of life in nutritional and activity behaviour has changed. As a consequence, parallel trends of an epidemic of overweight and a decline in external skeletal robusticity are observed in children and adolescents. Aim: We aim to develop reference centiles for external skeletal robusticity of European girls and boys aged 0 to 18 years using the Frame Index as an indicator and identify population specific age-related patterns. Methods: We analysed cross-sectional & longitudinal data on body height and elbow breadth of boys and girls from Europe (0-18 years, n = 41.679), India (7-18 years, n = 3.297) and South Africa (3-18 years, n = 4.346). As an indicator of external skeletal robusticity Frame Index after Frisancho (1990) was used. We developed centiles for boys and girls using the LMS-method and its extension. Results: Boys have greater external skeletal robusticity than girls. Whereas in girls Frame Index decreases continuously during growth, an increase of Frame Index from 12 to 16 years in European boys can be observed. Indian and South African boys are almost similar in Frame Index to European boys. In girls, the pattern is slightly different. Whereas South African girls are similar to European girls, Indian girls show a lesser external skeletal robusticity. Conclusion: Accurate references for external skeletal robusticity are needed to evaluate if skeletal development is adequate per age. They should be used to monitor effects of changes in way of life and physical activity levels in children and adolescents to avoid negative health outcomes like osteoporosis and arthrosis.

    International experiences with power sector restructuring and the resultant impacts on bulk power grid operations and planning may provide insight into policy questions for the evolving United States power grid as resource mixes are changing in response to fuel prices, an aging generation fleet and to meet climate goals. Australia, Germany, Japan and the UK were selected to represent a range in the level and attributes of electricity industry liberalization in order to draw comparisons across a variety of regions in the United States such as California, ERCOT, the Southwest Power Pool and the Southeast Reliability Region. The study draws conclusions through a literature review of the four case study countries with regards to the changing resource mix and the electricity industry sector structure and their impact on grid operations and planning. This paper derives lessons learned and synthesizes implications for the United States based on answers to the above questions and the challenges faced by the four selected countries. Each country was examined to determine the challenges to their bulk power sector based on their changing resource mix, market structure, policies driving the changing resource mix, and policies driving restructuring. Each countries’ approach to solving those changes was examined, as well as how each country’s market structure either exacerbated or mitigated the approaches to solving the challenges to their bulk power grid operations and planning. All countries’ policies encourage renewable energy generation. One significant finding included the low- to zero-marginal cost of intermittent renewables and its potential negative impact on long-term resource adequacy. No dominant solution has emerged although a capacity market was introduced in the UK and is being contemplated in Japan. Germany has proposed the Energy Market 2.0 to encourage flexible generation investment. The grid operator in Australia proposed several approaches to maintaining

    2016-06-01

    Full Text Available The article deals with the complex and controversial problems of the new regional communities’ formation and the impact of the interethnic relations sphere on them. The author notes that the processes of interaction between representatives of different cultures and civilizations, ethnic groups and religions have become increasingly controversial and tense in the context of continuous social dynamics. Similarly to the Russian society as a whole, regional communities are in a state of transitivity. They get transformed, they acquire new qualities such as multicasting and heterogeneity, multi-ethnicity and multi-confessionalism, fragmentarity and multiculturality. This fact increases the risks and uncertainties, problematizes future prospects. National non-governmental organizations are increasingly positioning themselves as civil society institutions at the present stage of social development at the regional level. They perform a difficult dual task: on the one hand, they ensure the preservation and development of history, native language, culture, ethnic traditions, and on the other hand, they work on the integration, on the common identity and the Russian nation formation. On the territory of the Volgograd region, largely due to the active cooperation of regional authorities and local authorities with national public associations, international and inter-confessional relations are stable. The basis of such activity is respect for history, native language, culture, tradition, religion, national dignity of all people in the region, regardless of their belonging to a certain ethnic group or religion. Over two decades of accumulated considerable experience of joint inter-ethnic dialogue and cooperation, provided tolerance and peace, harmony and mutual understanding between people of different ethnicities and religions in the country.

    We compared clinic-referred youth with ADHD + sluggish cognitive tempo (SCT; n = 34), ADHD Only ( n = 108), and SCT Only ( n = 22) on demographics, co-occurring symptomatology, comorbid diagnoses, and social functioning. In total, 164 youth (age = 6-17 years, M = 9.97) and their parent(s) presented to an outpatient clinic for a psychoeducational assessment. Between-group analyses and regressions were used to examine study variables. SCT groups were older and exhibited more parent-reported internalizing problems, externalizing problems, sleep problems, and social withdrawal on the Child Behavior Checklist. No significant differences emerged between groups on the Teacher Report Form. Regression analyses involving multiple covariates revealed that SCT symptoms were uniquely related to social withdrawal but not general social problems. Based on parent report, SCT symptoms have a unique relationship with internalizing problems, sleep problems, and social withdrawal. Future research should explore correlates of SCT in youth using multiple informants.

    2004-01-01

    InSPACE is a microgravity fluid physics experiment that was operated on the International Space Station (ISS) in the Microgravity Science Glovebox from late March 2003 through early July 2003. (InSPACE is an acronym for Investigating the Structure of Paramagnetic Aggregates From Colloidal Emulsions.) The purpose of the experiment is to obtain fundamental data of the complex properties of an exciting class of smart materials termed magnetorheological (MR) fluids. MR fluids are suspensions, or colloids, comprised of small (micrometer-sized) superparamagnetic particles in a nonmagnetic medium. Colloids are suspensions of very small particles suspended in a liquid. (Examples of other colloids are blood, milk, and paint.) These controllable fluids can quickly transition into a nearly solid state when exposed to a magnetic field and return to their original liquid state when the magnetic field is removed. Controlling the strength of the magnetic field can control the relative stiffness of these fluids. MR fluids can be used to improve or develop new seat suspensions, robotics, clutches, airplane landing gear, and vibration damping systems. The principal investigator for InSPACE is Professor Alice P. Gast of the Massachusetts Institute of Technology (MIT). The InSPACE hardware was developed at the NASA Glenn Research Center. The InSPACE samples were delivered to the ISS in November 2002, on the Space Shuttle Endeavour, on Space Station Utilization Flight UF-2/STS113. Operations began on March 31, 2003, with the processing of three different particle size samples at multiple test parameters. This investigation focused on determining the structural organization of MR colloidal aggregates when exposed to a pulsing magnetic field. On Earth, the aggregates take the shape of footballs with spiky tips. This characteristic shape may be influenced by the pull of gravity, which causes most particles initially suspended in the fluid to sediment, (i.e., settle and collect at the

Gestational age ranged from 26 to 40 weeks. Twelve patients were hydropic at presentation (6 with SVT and 6 AF. Four fetuses with SVT showed structural abnormalities (two with Ebsten's anomaly and two with VSD. All patients were admitted to the Fetal Cardiology Unit for monitoring and treatment. Among 17 fetuses with SVT, twelve showed good response to digoxin administration, but this drug was not useful in any of the patients with flutter. In two patients with SVT and in six with AF, the pregnancy was interrupted to perform post-natal cardioversion. The mortality rate was 3/17 in the SVT group (including 2 patients with ebstein's anomaly and 0/8 in the flutter group CONCLUSION: Fetal supraventricular tachyarrithmias are rare in the general population. Nevertheless, the fetus may present with severe heart failure and death. Considering the satisfactory therapeutic response, accurate diagnosis and early treatment of these conditions are extremely important.

    1999-01-01

    The IAEA International Physical protection Advisory Service (IPPAS) provides advice to Member States to assist them in strengthening the effectiveness of their national physical protection system whilst recognizing the ultimate responsibility for physical protection is that of the Member State. The IPPAS is available to all countries with nuclear materials and facilities. The basic concepts, purposes and functions of physical protection are provided in INFCIR/225, 'The Physical Protection of Nuclear Material and Nuclear Facilities' as amended from time to time and 'the Convention on the Physical Protection of Nuclear Material (INFCIR/247/Rev.1). The guidance given in INFCIR/225 recognizes that implementation of these requirements vary from country to country depending on their existing constitutional, legal and administrative systems; the assessment of the threat for the potential theft of nuclear material or sabotage of nuclear facilities; the technical skills and professional and financial resources available to the competent authority; and social customs and cultural traditions. IPPAS missions are performance oriented in that they accept different approaches to the implementation of national physical protection system

    Because there are no reference standards for body mass index (BMI) in Saudi children, we established BMI reference percentiles for normal Saudi Arabian children and adolescents and compared them with international standards. Data from a stratified multistage probability sample were collected from the 13 health regions in Saudi Arabia, as part of a nationwide health profile survey of Saudi Arabian children and adolescents conducted to establish normal physical growth references. Selected households were visited by a trained team. Weight and length/height were measured and recorded following the WHO recommended procedures using the same equipment, which were subjected to both calibration and intra/interobserver variations. Survey of 11 874 eligible households yielded 35 275 full-term and healthy children and adolescents who were subjected to anthropometric measurements. Four BMI curves were produced, from birth to 36 months and 2 to 19 years for girls and boys. The 3rd, 5th, 10th ,25th , 5oth , 75th ,85th , 90th , 95th , and 97th percentiles were produced and compared with the WHO and CDC BMI charts. In the higher percentiles, the Saudi children differed from Western counterparts, indicating that Saudi children have equal or higher BMIs. The BMI curves reflect statistically representative BMI values for Saudi Arabian children and adolescents. (author)

  4. An old method facing a new challenge: re-visiting housekeeping proteins as internal reference control for neuroscience research.

    Li, Rena; Shen, Yong

    2013-04-19

    The study of specific target protein expression is often performed by western blotting, a commonly used method to measure the protein expression in neuroscience research by specific antibodies. Housekeeping proteins are used as an internal control for protein loading as well as reference in the western blotting analysis. This practice is based on the belief that such housekeeping genes are considered to be ubiquitously and constitutively expressed in every tissue and produce the minimal essential transcripts necessary for normal cellular function. The most commonly used housekeeping proteins are β-actin, β-tubulin, and glyceraldehyde 3-phosphate dehydrogenase (GAPDH). However, recent studies have shown significant variation in some housekeeping genes both at the mRNA and protein levels in various neuropathological events, such as spinal cord injury and Alzheimer's diseases. Changes of housekeeping genes are also induced by non-neuronal diseases in various tissues. Therefore, these discoveries raise a potential concern regarding whether using a housekeeping protein as an internal standard for target protein analysis is an appropriate practice. This minireview will focus on (I) the effects of neuronal and non-neuronal diseases, experimental condition, and tissue-specific roles on alteration of housekeeping genes, and (II) alternative internal standards for gene and protein expression analysis.

The latest set of basic recommendations was adopted by the Commission on 17 January 1977, and subsequently published as ICRP Publication 26. This document has met with a wider interest than any of the previous ICRP recommendations. It has been considered to mark a radical change in the protection policy advocated by ICRP. It is not often appreciated that recommendations which are believed to be 'new' in ICRP Publication 26 had already been made in ICRP Publication 9 more than ten years earlier. In any event, ICRP Publication 26 has had a substantial impact on regulatory work in countries all over the world. It forms the basis for the Basic Safety Standards of the international organizations IAEA, ILO, OECD/NEA and WHO. The paper refers to the experience gained in using the new ICRP recommendations over the five years that have passed since ICRP Publication 26 was adopted and discusses some of the problems that have arisen in the practical application of the new recommendations in various countries.

    2016-12-01

    Full Text Available Asian students make up the largest proportion of international students who study in the United States. Seeking a degree in higher education can be challenging for any student, but Asian students often encounter more obstacles to completion than many other international and domestic students. Culture, family and health concerns, and safety are some of the largest concerns that this study found among Asian students in the US. The study found that East-Asian international students had more issues than students from other parts of Asia and difficulty with the English language was of major importance to respondents. In addition, safety is an issue that Asian students were concerned with while studying in the US. The study was exploratory in nature and informs the field on future avenues of research.

    Europe's first Ebola virus disease (EVD) case was diagnosed in our hospital. There was an unjustified panic in the population because of an imbalance of credibility assigned to the media as opposed to scientific information. A reinforcement of hospital internal communication was needed to keep health care workers informed with up-to-date scientific EVD information. The proactive management of information flow to both internal and external actors is required to reduce unjustified fear within the public.

    2014-01-01

    Full Text Available Education exchanges are a key element of public diplomacy for most countries that considered effective in that domain of foreign policy activities. Education exchanges are attributed an important role in the post-war peace settlement between Germany and France and in determining the outcome of the Cold war. Relevant aspects of public diplomacy remain key elements of foreign policy instruments of the US, Germany and many other countries. Russia has been increasingly active in public diplomacy in the past decade and the role of education exchanges has been increasing which is also demonstrated by a growing number of expert publications on the subject. However the strategy, the quality of organization and the use of modern technologies remain at a relatively low level which leads to an inefficient use of resources. Priority issues that can be a core of Russia's public diplomacy (and foreign policy in general. Moreover, systemic work would be required to evaluate efficiency of current and complete projects which would allow determine effectiveness of programs and appropriateness of resources used. Education exchanges need to be targeted at both bringing international students to Russia and assisting Russian students to study internationally and professors to teach abroad. Finally, international best practices show that there is a need to maintain connections with international exchanges alumni and assist them to maintain connections with each other including with the use of modern technologies.

    Earthquake experience data was recognized as an efficient basis for verification of seismic adequacy of equipment installed on NPPs. This paper is meant to initiate a database setup in order to use the seismic experience to establish the generic seismic resistance of NPPs equipment applicable namely to the Middle and East European countries. Such earthquake experience database should be then compared to the already existing and well-known SQUG-GIP database. To set up such an operational earthquake database will require an important amount of effort. It must be understood that this goal can be achieved only based on a long term permanent activities and coordinated cooperation of various institutions. (author)

    Karina Vladimirovna Sayapina

    2016-12-01

    Full Text Available The article is devoted to analysis of peculiarities in forming and promoting Russian and international innovation clusters. Cluster's orientation to innovation is its significant feature: cluster approach is fully realized in many countries all over the world, because it is the cluster frames which increase opportunity of creating a unique innovation idea, together with speed and effectiveness of commercialization process. Innovation potential, sufficiency of productional and distributional facilities, long-term management strategy, optimization of external and internal cluster connections are key features to provide competitive advantages of the innovation cluster. In the article key principals of innovation cluster formation in the leading states are considered: the core of cluster is predominantly a scientific research center or higher institution, with large and small industrial companies as the cluster participants, with significant governmental support. In the article the main tendencies of innovation cluster international development are underlined: companies' efforts to increase competitiveness on basis of vertical integration; horizontal integration as an attempt to decrease production costs through specialization improvement; conglomerate consolidation to take down risks through diversification; growth of transnational innovation clusters of the largest industrial companies to gain point on the global market. Measures of forming efforts to effective promotion of innovation clusters on international markets are interaction of companies with specialized technological platforms, participation in federal and regional events to stimulate research and development activity; realization of permanent comparative analysis with leading foreign practices under key factors of development, and formation of innovation ecosystem, including business-incubators, accelerators, venture funds, personnel education and technological enterpreneurship in

    2014-12-01

    Full Text Available The purpose of this paper is to examine the requirements and successes of the New International Financial Architecture (NIFA on transparency and corporate governance from a global perspective with a special focus on Africa. In recent years, transparency, accountability and governance have become key topics with many countries around the world having adopted International Financial Reporting Standards (IFRS and corporate governance codes. The outcomes of these initiatives have been unconvincing. Desktop research was used to gather literature and data on compliance with corporate governance codes and International Financial Reporting Standards (IFRS and other NIFA requirements. This study established that in spite of many regional and global initiatives by the World Bank and relevant regulators, compliance with IFRS and governance in parts of Africa has yet to reach its best level and guidelines are not fully followed leading to opportunities for improvement and policy adjustments. This research has implications and uses for both global and local institutions and regulators concerned with economic stability and growth including the World Bank, central banks, capital markets and boards of companies and the government in general. The findings contribute to governance debates by providing additional perspectives from Africa on compliance with accounting standards and codes in a region where research and corporate governance and reporting issues are still confusing.

    2011-06-01

    Full Text Available Abstract Background Few studies have addressed the challenges that international medical students face and there is a dearth of information on the behavioural strategies these students adopt to successfully progress through their academic program in the face of substantial difficulties of language barrier, curriculum overload, financial constraints and assessment tasks that require high proficiency in communication skills. Methods This study was designed primarily with the aim of enhancing understanding of the coping strategies, skill perceptions and knowledge of assessment expectations of international students as they progress through the third and fourth years of their medical degree at the School of Medicine, University of Tasmania, Australia. Results Survey, focus group discussion and individual interviews revealed that language barriers, communication skills, cultural differences, financial burdens, heavy workloads and discriminatory bottlenecks were key factors that hindered their adaptation to the Australian culture. Quantitative analyses of their examination results showed that there were highly significant (p Conclusions Despite the challenges, these students have adopted commendable coping strategies and progressed through the course largely due to their high sense of responsibility towards their family, their focus on the goal of graduating as medical doctors and their support networks. It was concluded that faculty needs to provide both academic and moral support to their international medical students at three major intervention points, namely point of entry, mid way through the course and at the end of the course to enhance their coping skills and academic progression. Finally, appropriate recommendations were made.

  13. An image-based skeletal dosimetry model for the ICRP reference adult female—internal electron sources

    2016-12-01

    An image-based skeletal dosimetry model for internal electron sources was created for the ICRP-defined reference adult female. Many previous skeletal dosimetry models, which are still employed in commonly used internal dosimetry software, do not properly account for electron escape from trabecular spongiosa, electron cross-fire from cortical bone, and the impact of marrow cellularity on active marrow self-irradiation. Furthermore, these existing models do not employ the current ICRP definition of a 50 µm bone endosteum (or shallow marrow). Each of these limitations was addressed in the present study. Electron transport was completed to determine specific absorbed fractions to both active and shallow marrow of the skeletal regions of the University of Florida reference adult female. The skeletal macrostructure and microstructure were modeled separately. The bone macrostructure was based on the whole-body hybrid computational phantom of the UF series of reference models, while the bone microstructure was derived from microCT images of skeletal region samples taken from a 45 years-old female cadaver. The active and shallow marrow are typically adopted as surrogate tissue regions for the hematopoietic stem cells and osteoprogenitor cells, respectively. Source tissues included active marrow, inactive marrow, trabecular bone volume, trabecular bone surfaces, cortical bone volume, and cortical bone surfaces. Marrow cellularity was varied from 10 to 100 percent for active marrow self-irradiation. All other sources were run at the defined ICRP Publication 70 cellularity for each bone site. A total of 33 discrete electron energies, ranging from 1 keV to 10 MeV, were either simulated or analytically modeled. The method of combining skeletal macrostructure and microstructure absorbed fractions assessed using MCNPX electron transport was found to yield results similar to those determined with the PIRT model applied to the UF adult male skeletal dosimetry model.

    The adoption waiting period is a powerful stressor that can affect the well-being and configuration of future family life. Adoption research and practice have not paid enough attention to this phase. The principal aim of this study is to address prospective adoptive parents' experience of and coping with this period. For this purpose, 63 families answered a feelings scale, a coping resources scale and a needs questionnaire, all elaborated for the study. Results show that a shorter length of waiting time, using cognitive and learning coping strategies and associative participation were related to a better general experience of adoption whereas process-centred strategies were related to a worse experience of adoption. Families would like to see more speed in the process, more warmth and humanity in their relation with institutions and better information about their expedients. We conclude by proposing some activities and services during the waiting period that could be useful for post adoption.

    The Lf-unit, which is used in the control of diphtheria and tetanus toxoid production and in some countries also to follow immunization of horses for production of antitoxins, has hitherto been defined by means of antitoxin preparations. A diphtheria toxoid and a tetanus toxoid preparation, both freeze-dried, were examined in an international collaborative study for their suitability to serve as reference reagents in the flocculation tests and for defining the Lf-units. It was shown that flocculation tests using the reference toxoids are very reproducible and reliable and the WHO Expert Committee on Biological Standardization established: the toxoid called DIFT as the International Reference Reagent of Diphtheria Toxoid for Flocculation Test with a defined content of 900 Lf-units of diphtheria toxoid per ampoule; and the toxoid called TEFT as the International Reference Reagent of Tetanus Toxoid for Flocculation Test with a defined content of 1000 Lf-units of diphtheria toxoid per ampoule.

    2012-01-01

    Under a microscope, atomic oxygen (AO) exposed silicone surfaces are crazed and seen as "islands" separated by numerous crack lines, much analogous to mud-tile cracks. This research characterized and compared the degree of AO degradation of silicones by analyzing optical microscope images of samples exposed to low Earth orbit (LEO) AO as part of the Spacecraft Silicone Experiment. The Spacecraft Silicone Experiment consisted of eight DC 93-500 silicone samples exposed to eight different AO fluence levels (ranged from 1.46 to 8.43 10(exp 21) atoms/sq cm) during two different Materials International Space Station Experiment (MISSE) missions. Image analysis software was used to analyze images taken using a digital camera. To describe the morphological degradation of each AO exposed flight sample, three different parameters were selected and estimated: (1) average area of islands was determined and found to be in the 1000 to 3100 sq mm range; (2) total length of crack lines per unit area of the sample surface were determined and found to be in the range of 27 to 59 mm of crack length per sq mm of sample surface; and (3) the fraction of sample surface area that is occupied by crack lines was determined and found to be in the 25 to 56 percent range. In addition, average crack width can be estimated from crack length and crack area measurements and was calculated to be about 10 mm. Among the parameters studied, the fraction of sample surface area that is occupied by crack lines is believed to be most useful in characterizing the degree of silicone conversion to silicates by AO because its value steadily increases with increasing fluence over the entire fluence range. A series of SEM images from the eight samples exposed to different AO fluences suggest a complex sequence of surface stress due to surface shrinkage and crack formation, followed by re-distribution of stress and shrinking rate on the sample surface. Energy dispersive spectra (EDS) indicated that upon AO

    Olofsson, P.T.; Blomqvist, L.; Fridell, K.; Aspelin, P.

    2016-01-01

    Introduction: There are strengths, weaknesses, opportunities and challenges when outsourcing advanced radiological examinations such as magnetic resonance examinations from university hospitals to external private institutions. Aim: The aim of this study was to explore the experiences of referring physicians when their referrals for radiological examinations are outsourced from a university hospital in Stockholm, Sweden. Method: This qualitative study is a part of a larger study investigating the consequences of outsourcing referrals for radiological examinations from a university hospital to private external units. Ten referring physicians from orthopedic and oncology departments, representing clinics with large volumes of radiological referrals at a university hospital, were interviewed. Results: The results showed that the requirements for radiological services differ between these specialties. The overall opinion was that examinations performed by external radiology departments needed additional re-assessment work which causes higher costs for their clinics. This indicates that there is insufficient communication between referring physicians and the radiological department at the University Hospital. Conclusions: For better planning of radiological services, radiology departments must consider the referring physicians' needs and develop suitable contract when organizing the practice of outsourcing. The management structure in radiology departments and communication between referring physicians and radiologists in the radiology departments should be studied further, to promote better understanding and improve the efficiency of the outsourcing process. - Highlights: • The requirements for radiological services differ between specialties. • Outsourced examinations need more frequent re-assessment. • Outsourced examinations cause higher costs for referring departments. • Outsourcing radiological examinations entail more administrative work.

    Few studies have addressed the challenges that international medical students face and there is a dearth of information on the behavioural strategies these students adopt to successfully progress through their academic program in the face of substantial difficulties of language barrier, curriculum overload, financial constraints and assessment tasks that require high proficiency in communication skills. This study was designed primarily with the aim of enhancing understanding of the coping strategies, skill perceptions and knowledge of assessment expectations of international students as they progress through the third and fourth years of their medical degree at the School of Medicine, University of Tasmania, Australia. Survey, focus group discussion and individual interviews revealed that language barriers, communication skills, cultural differences, financial burdens, heavy workloads and discriminatory bottlenecks were key factors that hindered their adaptation to the Australian culture. Quantitative analyses of their examination results showed that there were highly significant (p student performances in multiple choice questions, short answer questions and objective structured clinical examinations (70.3%, 49.7% & 61.7% respectively), indicating existence of communication issues. Despite the challenges, these students have adopted commendable coping strategies and progressed through the course largely due to their high sense of responsibility towards their family, their focus on the goal of graduating as medical doctors and their support networks. It was concluded that faculty needs to provide both academic and moral support to their international medical students at three major intervention points, namely point of entry, mid way through the course and at the end of the course to enhance their coping skills and academic progression. Finally, appropriate recommendations were made.

    The International Science Olympiad is an international intellectual olympic in which students, aging under 20 and who have not entered university, compete using their creative problem solving skills in the field of science. Many nations participate in the Olympiad with great interest, for this competition is a global youth science contest which is also used to measure national basic science levels. However in Korea, benefits for Olympiad participants were reduced because issues were risen that the Olympiad could intensify private education. This resulted in a continuous decrease in the number of applicants, bringing national competitiveness deterioration to concern. Therefore in this study, we identified the problems by analyzing the actual conditions of Olympiad participants' private education, and sought support plans to activate Olympiad participation. For this use, we conducted a survey of 367 summer school and winter school acceptees in 9 branches. 68.9% of the students were preparing for the Olympiad by private education, and the highest percentage answered that their private education expenses were an average of 3~5 million won. Olympiad preparation took up 30~50% of all private education, showing that private education greatly influences the preparing processes for the Olympiad. Meanwhile the participants perceived that in order to reduce Olympiad-related private education, the following should be implemented priority: supply of free high-quality on-line education materials, and easy access to Olympiad related information. It was also suggested that the most effective and needed education methods were school olympiad preparation classes, on-line education expansion, and special lectures and mentoring from olympiad-experienced senior representatives. Additionally, as methods to activate Olympiad participation, it was thought that award records should be allowed to be used in college applications by enabling award records into student records and special

    This thesis contains five essays on the regulation of electricity distribution networks, each presenting a different point of view. Two essays use US data to demonstrate that incentive-based regulation has valuable application within a management setting and can lead to gaming behaviour within a regulatory setting. One essay discusses the lessons that can be drawn from the failed first electricity distribution price control review in the Netherlands. One essay presents the views of 75 international regulation managers and gives recommendations on ways to improve the regulatory quality and process. The final essay analyses the economic consequences of the forced ownership unbundling of the electricity distribution networks in 1998 in New Zealand, and draws lessons for future structural remedies that may be sought in other countries

    Man power development is an essential key to success in implementing nuclear projects, especially when maximum local participation is an important issue in every sector of nuclear industry. Bearing this in mind, the Korean Atomic Energy Research Institute (KAERI) founded the Nuclear Training Center (NTC). The Center began to train technical personnel in the fields of radioisotope utilization and radiation protection in 1960s. During the first stage of nuclear power project in ROK in 1970s, the main effort was exerted to the training of those in nuclear power and nuclear engineering sectors. During the stage of increased technical self-reliance in 1980s, its training role was extended to the implementation of more specific training courses on nuclear power and safety fields. As of the end of 1995, about 23,000 people received the training courses. In an attempt to upgrade the nuclear technology, the advanced training courses at the NTC by invited foreign experts and by IAEA technical cooperation program have been implemented. Also the training under IAEA Regional Cooperative Agreement in Asia Pacific Region has been offered. The change of the NTC to the International Training Center is recommended. (K.I.)

    Full Text Available The article reviews and analyzes existing interpretations of the term of «energy security», which are used by international organizations, individual countries, and foreign scientists. As result of a generalization of the numerous existing conceptual-methodical and substantive approaches to the definition of energy security, its main components and possible ways of its ensuring, it has been found that the concept of energy security includes many multifactor components that are interconnected by numerous functional linkages, including economic, political, social, and ecological aspects. The issues related to geology, geography, and time factor have impact on interpretation of energy security. But in general, energy security can be seen in a one-aspect dimension that is largely based on the security of energy supplies (availability of energy resources and in a multi-aspect dimension which, in addition to the security of energy supplies, also takes into consideration a number of other important interrelated aspects of energy security, particularly in the areas of accessibility of energy resources, energy efficiency, and environmental safety.

    Objectives: This article reports and analyses conversation with eight international educators in Europe, Canada, the United States, New Zealand and Australia. All are managing the impact of technology in different ways (reactive and pro-active, at different levels (pre-primary through to senior citizen, in different roles (teachers, administrators and senior managers and in different contexts (schools and universities. Method: Open-ended conversations with educators and educational administrators in developed countries were recorded, transcribed and analysed. The qualitative analysis of the content was done in the style of ‘open coding’ and ‘selective coding’ using a qualitative content analysis tool. Results: Whilst technology is still seen to drive much thinking, it is found that that success is not derived from the technology, but from a full and proper understanding of the needs and aspirations of those who are directly involved in educational processes, and by means of a managerial focus that properly recognises the context within which an institution exists. Conclusion: Whilst this result might be expected, the detailed analysis of the findings further reveals the need to manage investments in educational technologies at different levels and in different ways.

  1. International Experience in Standards and Labeling Programs for Rice Cookers

    Energy Technology Data Exchange (ETDEWEB)

    Zhou, Nan; Zheng, Nina

    2008-05-01

    China has had an active program on energy efficiency standards for household appliances since the mid-1990s. Rice cooker is among the first to be subject to such mandatory regulation, since it is one of the most prevalent electric appliances in Chinese households. Since first introduced in 1989, the minimum energy efficiency standard for rice cookers has not been revised. Therefore, the potential for energy saving is considerable. Initial analysis from CNIS indicates that potential carbon savings is likely to reach 7.6 million tons of CO2 by the 10th year of the standard implementation. Since September 2007, CNIS has been working with various groups to develop the new standard for rice cookers. With The Energy Foundation's support, LBNL has assisted CNIS in the revision of the minimum energy efficiency standard for rice cookers that is expected to be effective in 2009. Specifically, work has been in the following areas: assistance in developing consumer survey on usage pattern of rice cookers, review of international standards, review of international test procedures, comparison of the international standards and test procedures, and assessment of technical options of reducing energy use. This report particularly summarizes the findings of reviewing international standards and technical options of reducing energy consumption. The report consists of an overview of rice cooker standards and labeling programs and testing procedures in Hong Kong, South Korea, Japan and Thailand, and Japan's case study in developing energy efficiency rice cooker technologies and rice cooker efficiency programs. The results from the analysis can be summarized as the follows: Hong Kong has a Voluntary Energy Efficiency Labeling scheme for electric rice cookers initiated in 2001, with revision implemented in 2007; South Korea has both MEPS and Mandatory Energy Efficiency Label targeting the same category of rice cookers as Hong Kong; Thailand's voluntary endorsement labeling

    1988-01-01

    Radioisotope production has been carried out in the German Democratic Republic for 30 years. Based on a 10 MW research reactor, a cyclotron and certain irradiation facilities at units of national nuclear power stations, a widespread assortment of radioisotopes is produced with emphasis to radiopharmaceuticals as the main materials. Domestic production covers the national demand in these products where the production is technologically feasible under our conditions. A complete supply of the users in the country (more than 7000 licences) is accomplished by an intense co-operation with neighbouring countries, including mutual assistance in reactor shut down periods and supply with special radioactive materials and products. International co-operation within the framework of the IAEA takes place, mainly as scientific and technological assistance to many developing countries. (author)

  6. The Internal/External Frame of Reference Model Revisited: Incorporating General Cognitive Ability and General Academic Self-Concept.

    Brunner, Martin; Lüdtke, Oliver; Trautwein, Ulrich

    2008-01-01

    The internal/external frame of reference model (I/E model; Marsh, 1986 ) is a highly influential model of self-concept formation, which predicts that domain-specific abilities have positive effects on academic self-concepts in the corresponding domain and negative effects across domains. Investigations of the I/E model do not typically incorporate general cognitive ability or general academic self-concept. This article investigates alternative measurement models for domain-specific and domain-general cognitive abilities and academic self-concepts within an extended I/E model framework using representative data from 25,301 9th-grade students. Empirical support was found for the external validity of a new measurement model for academic self-concepts with respect to key student characteristics (gender, school satisfaction, educational aspirations, domain-specific interests, grades). Moreover, the basic predictions of the I/E model were confirmed, and the new extension of the traditional I/E model permitted meaningful relations to be drawn between domain-general cognitive ability and domain-general academic self-concept as well as between the domain-specific elements of the model.

    2017-03-01

    The purpose of this work was to validate GATE-based clinical scale absorbed dose calculations in nuclear medicine dosimetry. GATE (version 6.2) and MCNPX (version 2.7.a) were used to derive dosimetric parameters (absorbed fractions, specific absorbed fractions and S-values) for the reference female computational model proposed by the International Commission on Radiological Protection in ICRP report 110. Monoenergetic photons and electrons (from 50 keV to 2 MeV) and four isotopes currently used in nuclear medicine (fluorine-18, lutetium-177, iodine-131 and yttrium-90) were investigated. Absorbed fractions, specific absorbed fractions and S-values were generated with GATE and MCNPX for 12 regions of interest in the ICRP 110 female computational model, thereby leading to 144 source/target pair configurations. Relative differences between GATE and MCNPX obtained in specific configurations (self-irradiation or cross-irradiation) are presented. Relative differences in absorbed fractions, specific absorbed fractions or S-values are below 10%, and in most cases less than 5%. Dosimetric results generated with GATE for the 12 volumes of interest are available as supplemental data. GATE can be safely used for radiopharmaceutical dosimetry at the clinical scale. This makes GATE a viable option for Monte Carlo modelling of both imaging and absorbed dose in nuclear medicine.

    Marsh's internal/external (I/E) frame of reference model depicts the relationship between achievement and self-concept in specific academic domains. Few efforts have been made to examine concurrent relationships among cognitive ability, achievement, and academic self-concept (ASC) within an I/E model framework. To simultaneously examine the influences of domain-specific cognitive ability and grades on domain self-concept in an extended I/E model, including the indirect effect of domain-specific cognitive ability on domain self-concept via grades. Tenth grade respondents (628 male, 452 female) to a national adolescent survey conducted in Taiwan. Respondents completed surveys designed to measure maths and verbal aptitudes. Data on Maths and Chinese class grades and self-concepts were also collected. Statistically significant and positive path coefficients were found between cognitive ability and self-concept in the same domain (direct effect) and between these two constructs via grades (indirect effect). The cross-domain effects of either ability or grades on ASC were negatively significant. Taiwanese 10th graders tend to evaluate their ASCs based on a mix of ability and achievement, with achievement as a mediator exceeding ability as a predictor. In addition, the cross-domain effects suggest that Taiwanese students are likely to view Maths and verbal abilities and achievements as distinctly different. ©2011 The British Psychological Society.

  11. Opposition to nuclear power: a review of international experience

    Energy Technology Data Exchange (ETDEWEB)

    Surrey, J.; Huggett, C.

    1976-12-01

    This paper examines the rise of opposition to nuclear power in the USA, the Federal Republic of Germany, France, Sweden, and Japan. It explores the course that opposition has taken, the issues on which it has focused, the factors that have influenced it, and the problems it poses for public decision making. Opinions differ about the causes of nuclear opposition. Indeed, it is probable that a variety of factors have contributed, including cultural and political values regarding continued economic and energy growth and fears of deliberate large-scale violence with the spread of radioactive materials, the protest movements against nuclear weapons testing, the upsurge in environmental concern in the 1960s, the movement towards greater social responsibility in science, and a growing distrust of ''the Establishment''--particularly in the USA because of Watergate. The upsurge in concern was reflected in greater attention to environmental matters in the mass media, schools, universities, and the international agencies. It is important to recognize that this concern cuts across conventional left-right divisions of politics. Radicals, communists, and conservatives can be found among both the proponents and the critics. These difficulties facing the policy maker are accentuated by the amorphous nature both of the opposition and the issues which have received attention and by the evidence of many opinion surveys: that more people are in favor of nuclear power than oppose it, but the majority are uncertain and do not understand the issues. For purposes of analysis it is useful to distinguish between three types of opposition--nuclear-specific, site-specific, and that related to planning and consent procedures. (MCW)

  4. When referring physicians and researchers disagree on equipoise: the TOTAL trial experience.

    Rodrigues, H C M L; Deprest, J; v d Berg, P P

    2011-06-01

    In this article, we reflect on whether randomized controlled trials (RCTs) are adequate for the clinical evaluation of maternal-fetal surgery for congenital diaphragmatic hernia (CDH), focusing on the role of patients' preferences in the setting up of research protocols, on the requirement of equipoise and on the concept of therapeutic misconception (TM). We describe the conception and setting up of the tracheal occlusion (TO) to accelerate lung growth trial and analyze the ethical dilemmas faced by the research team during that time. Depending on the view adopted regarding the scope of equipoise, there are two ways of dealing with patient's preferences concerning fetoscopic endoluminal TO and expectant management during pregnancy for CDH. The solution adopted for fetoscopic endoluminal tracheal occlusion (FETO) is justified by the extended period of time it has been available to patients before the start of the RCT. Strong patient and referring physician preferences do not entail a right to have FETO, since it is a procedure of yet unproven efficacy and safety. In the future, to avoid the dilemmas posed by the TM and in name of the right of future generations of patients to have access to treatment of proven safety and efficacy, researchers must be able to plan RCT in due time.

    Liver abscess is a serious and an uncommon pediatric disease. Description of 20 pediatric patients with liver abscess admitted in "Ricardo Gutierrez" Children's Hospital, a Tertiary Reference Center of Buenos Aires, between 2009 and 2015. The hospitalization rate was 35/100.000 admissions. Median age was 5 years old, male/female ratio 4/1. Five patients (25%) had predisposing factors. Median days at diagnosis were 12. Fever 100%, prolonged fever 60%, abdominal pain 50%. The majority had leukocytosis and elevated CRP (median 160 mg/L). Liver enzymes were elevated in only 40% of patients. Ultrasonography detected 90%. A single abscess was observed in 60%; localized at right hepatic lobe, 65%. Purulent material was positive in 12/17 (70%) and bacteremia was present in 3/20 (15%). Wide empirical antibiotic therapy was used. Treatment shift was needed in four patients. The median days of intravenous antibiotics were 30 and the median of total treatment were 53. Surgical procedures were performed in 13/20 (65%). Community-acquired methicillin resistant Staphylococcus aureus (CA-MRSA) was the most frequent pathogen, especially in healthy children that associated skin or respiratory illness. Appropriate antibiotic treatment and eventual drainage allows good outcome without sequela or deaths.

    2009-01-01

    Muon ionization cooling provides the only practical solution to prepare high brilliance beams necessary for a neutrino factory or muon colliders. The muon ionization cooling experiment (MICE) is under development at the Rutherford Appleton Laboratory (UK). It comprises a dedicated beam line to generate a range of input emittance and momentum, with time-of-flight and Cherenkov detectors to ensure a pure muon beam. A first measurement of emittance is performed in the upstream magnetic spectrometer with a scintillating fiber tracker. A cooling cell will then follow, alternating energy loss in liquid hydrogen and RF acceleration. A second spectrometer identical to the first one and a particle identification system provide a measurement of the outgoing emittance. By July 2009 it is expected that the beam and first set of detectors will have been commissioned and a first measurement of input beam emittance may be reported. Along with the steps in the measurement of emittance reduction (cooling) that will follow later and in 2010. (authors)

  8. Nuclear energy and public opinion: an analysis of international experience

    1996-01-01

    Nuclear power occupies nowadays the third place among the different sources of energy in the world (17%), after coal (40%) and hydropower (18%). In the more developed countries of OECD (Organization for Economic Cooperation and Development), nuclear power already represents the second most utilized source of energy (coal; 40%, nuclear: 24%, hydro: 17%). It has been frequently stated that inadequate public information constitutes one of the main hindrances for broad use worldwide of nuclear power. However, in those countries where nuclear power has been more successful their well informed populations are generally in favor of its utilization. In countries like France, Japan, Republic of Korea and the U.S., big users of nuclear power, public opinion has been either in favor or has evolved favorably to the nuclear option. The experience in this field varies from country to country, depending mainly on their cultural and socio-political traditions. This report summarizes the situation in various countries as background information for possible adaptation to the conditions in Brazil. (author)

    2014-12-30

    The nature of hospital activity is changing in many countries, with some experiencing a broad trend towards the creation of hospital groups or chains and multi-hospital networks. This study seeks to contribute to the understanding of experiences in other countries about the extent to which different hospital "models" may provide lessons for hospital provision in England by means of a review of four countries: France, Germany, Ireland and the United States, with England included for comparison. We find that there has been a trend towards privatisation and the formation of hospital groups in France, Germany, and the United States although it is important to understand the underlying market structure in these countries explaining the drivers for hospital consolidation. Thus, and in contrast to the NHS, in France, Germany, and the United States, private hospitals contribute to the delivery of publicly funded healthcare services. There is limited evidence suggesting that different forms of hospital cooperation, such as hospital groups, networks or systems, may have different impacts on hospital performance. Available evidence suggests that hospital consolidation may lead to quality improvements as increased size allows for more costly investments and the spreading of investment risk. There is also evidence that a higher volume of certain services such as surgical procedures is associated with better quality of care. However, the association between size and efficiency is not clear-cut and there is a need to balance "quality risk" associated with low volumes and "access risk" associated with the closure of services at the local level.

  10. Entombment Using Cementitious Materials: Design Considerations and International Experience

    Energy Technology Data Exchange (ETDEWEB)

    Seitz, Roger Ray

    2002-08-01

    Cementitious materials have physical and chemical properties that are well suited for the requirements of radioactive waste management. Namely, the materials have low permeability and durability that is consistent with the time frame required for short-lived radionuclides to decay. Furthermore, cementitious materials can provide a long-term chemical environment that substantially reduces the mobility of some long-lived radionuclides of concern for decommissioning (e.g., C-14, Ni-63, Ni-59). Because of these properties, cementitious materials are common in low-level radioactive waste disposal facilities throughout the world and are an attractive option for entombment of nuclear facilities. This paper describes design considerations for cementitious barriers in the context of performance over time frames of a few hundreds of years (directed toward short-lived radionuclides) and time frames of thousands of years (directed towards longer-lived radionuclides). The emphasis is on providing an overview of concepts for entombment that take advantage of the properties of cementitious materials and experience from the design of low-level radioactive waste disposal facilities. A few examples of the previous use of cementitious materials for entombment of decommissioned nuclear facilities and proposals for the use in future decommissioning of nuclear reactors in a few countries are also included to provide global perspective.

    The growth of children is an indicator of health and society's wellbeing. Growth references are useful in monitoring a child's growth, which is a very important part of child care. Poland's growth references are not updated regularly. Although several growth reference ranges have been developed in Poland over recent years, sampling was restricted to urban populations of major cities. The aim of this study was to assess how well Polish children match with, or diverge from, regional charts and to compare them with international growth references. Four Polish and two international (WHO 2007 and USCDC2000) growth references were used to calculate the height, weight and BMI z-scores in a recent, large, population-representative sample of school-aged children and adolescents in Poland. The distributions of z-scores were analysed with descriptive and inferential statistical methods. Mean height z-scores calculated with the use of the WHO 2007 and USCDC2000 references were positive and significantly different from zero over the entire age range. The mean height z-score was closest to zero in the Poznan reference for boys (0.05) and Warszawa reference for girls (0.01). Median weight z-scores were positive under all weight references over the entire age range with only the exception of 18-year-old girls' weight z-score calculated relative to USCDC2000. Median BMI z-scores were positive in males in early childhood, decreasing with age. In the case of girls, the median BMI z-score calculated using WHO 2007 and USCDC2000 was close to zero in early childhood, decreased in adolescents and reached minimum values at age 18 years. Median BMI z-scores calculated with the use of the Lodz reference fluctuated between 0.05 and 0.2 over the studied age range. In this contemporary sample of Polish school-aged children, distributions of height, weight and BMI differed from those of children from the international growth references. These differences should be considered when using the

    1995-09-01

    A processed quartz sand (Wedron 510), mined from the St. Peter sandstone, has been characterized by a variety of chemical and physical methods for use as a reference porous media in transport model validation experiments. Wedron 510 sand was used in an intermediate-scale experiment involving migration of Ni, Li and Br through a 6-m high x 3-m diameter caisson. Ni and Li adsorption/desorption, and Li/Ni site-competition experiments yielded information on the importance of the trace mineral phases to adsorption of Li and Ni by the sand. The presence of an iron hydroxide coating similar to goethite on the sand grains is suggested by visual observation and leaching experiments. Kaolinite was identified by SEM and XRD as a significant trace mineral phase in the sand and occurs as small particles coating the sand grains. Quartz, the predominant constituent of the sand by weight, does not appear to contribute significantly to the adsorption properties of the sand. Qualitatively, the adsorption properties of the sand can be adequately modeled as a two-mineral system (goethite and kaolinite). The studies described in this report should provide a basis for understanding transport of Ni, Li and Br through porous media similar to the reference sand. Techniques were developed for obtaining parameter values for surface complexation and kinetic adsorption models for the sand and its mineral components. These constants can be used directly in coupled hydrogeochemical transport codes. The techniques should be useful for characterization of other natural materials and elements in high-level nuclear waste in support of coupled hydrogeochemical transport calculations for Yucca Mountain

    Full Text Available Background: There are several methods for counting platelets, of which the international flow reference method (IRM is considered to be the gold standard. We compared the platelet count given by this method to the count given by automated analyzers using other methods, such as optical fluorescence and impedance. Aims: The aim of this study is to compare the platelet counts obtained by Sysmex XE 2100 by Impedance (Sysmex-I, optical florescence (Sysmex-O and reported (Sysmex-R based on the switching algorithm and LH-750 by Impedance (LH-750 with the IRM in thrombocytopenic blood samples. To calculate the sensitivity, specificity, positive predictive value (PPV and negative predictive value (NPV of various technologies at the clinically relevant transfusion thresholds of 10 × 10 9 /l and 20 × 10 9 /l. Materials and Methods: A total of 118 blood samples with platelet count of <50 × 10 9 /l were selected for the study. Platelet counts of all samples were analyzed by all methods using the Sysmex analyzer, LH-750 and IRM in parallel within 6 h of collection. Statistical Analysis Used: Pearson correlation, bland Altman analysis, sensitivity and specificity, PPV and NPV. Results and Conclusions: Sysmex-R had the least Bias and 95% limits of agreement (95%LA range and thus correlated best with IRM values. LH-750 had a higher Bias compared to Sysmex-O and Sysmex-R, but a strikingly similar 95% LA ensures similar results in all three methods. In fact, in the oncology subset, it had the narrowest 95% LA, which made it the best performer in this subgroup. Of the three Sysmex results, Sysmex-I had the highest bias, widest 95% LA and highest potential risk of over transfusion. Hence, Sysmex-R and LH-750 were found to be reliable tools for estimation of platelet count in thrombocytopenic patients.

A careful imaging evaluation was performed to detail the abdominal anatomy (particularly the liver, inferior vena cava, spleen and pancreas, either to identify the number of organs or to evaluate the degree of organ sharing. RESULTS: There were eight sets of ischiopagus twins, seven sets of thoracopagus twins, three sets of omphalopagus twins, two sets of thoraco-omphalo-ischiopagus twins and one set of craniopagus twins. Nine pairs of conjoined twins could not be separated due to the complexity of the organs (mainly the liver and heart that were shared by both twins; these pairs included one set of ischiopagus twins, six sets of thoracopagus twins and one set of thoraco-omphalo-ischiopagus twins. Twelve sets were separated, including seven sets of ischiopagus twins, three sets of omphalopagus twins, one set of thoracopagus twins and one set of craniopagus conjoined twins. The abdominal wall was closed in the majority of patients with the use of mesh instead of the earlier method of using tissue expanders. The surgical survival rate was 66.7%, and one pair of twins who did not undergo separation is currently alive. CONCLUSION: A detailed anatomic study of the twins and surgical planning must precede separation. A well-prepared pediatric surgery team is sufficient to surgically manage conjoined twins.

    Full Text Available Romanian students′ appreciation towards international experience has been increasing as the number of students involved in international programs has been rising year by year. Also, students′ expectations upon graduation are more related to finding a good job, usually in multinationals. Studies conducted in Romania (Frunzaru et al., 2013 and (Nicolescu and Păun, 2009 showed that students give great attention to the skills they acquire after completing various programs, often their choices being focused on several successful areas and international programs. The joint projects of several universities and governmental authorities in Romania have aimed to develop the international dimension of education (IEMU, 2015. The results of implementing those projects could be revealed by students’ perception of international competences gained by curricula or international exchange programs. The purpose of this paper is to analyze the dynamics of Romanian and European graduates’ satisfaction with international experience and extracurricular resources accessed during university courses. Also, the article will analyze the dynamics of graduates′ career priorities in accordance with the skills provided upon graduation. The data are selected from Trendence Graduate Barometer - Romanian Edition and the analysis establishes relevant conclusions regarding the young Romanian graduates′ need to develop, in comparison with European graduates from 5-year statistic data (2012-2016. The conclusions include a comparison of international exchange programs and career priorities expectations among Romanian and other European graduates. Also, the paper will draw new research directions regarding students′ need for specialization especially in gaining international competences.

    Full Text Available Children in dentistry are traditionally described in terms of medical diagnosis and prevalence of oral disease. This approach gives little information regarding a child's capacity to maintain oral health or regarding the social determinants of oral health. The biopsychosocial approach, embodied in the International Classification of Functioning, Disability and Health - Child and Youth version (ICF-CY (WHO, provides a wider picture of a child's real-life experience, but practical tools for the application of this model are lacking. This article describes the preliminary empirical study necessary for development of such a tool - an ICF-CY Core Set for Oral Health. An ICF-CY questionnaire was used to identify the medical, functional, social and environmental context of 218 children and adolescents referred to special care or paediatric dental services in France, Sweden, Argentina and Ireland (mean age 8 years ± 3.6 yrs. International Classification of Disease (ICD-10 diagnoses included disorders of the nervous system (26.1%, Down syndrome (22.0%, mental retardation (17.0%, autistic disorders (16.1%, and dental anxiety alone (11.0%. The most frequently impaired items in the ICF Body functions domain were 'Intellectual functions', 'High-level cognitive functions', and 'Attention functions'. In the Activities and Participation domain, participation restriction was frequently reported for 25 items including 'Handling stress', 'Caring for body parts', 'Looking after one's health' and 'Speaking'. In the Environment domain, facilitating items included 'Support of friends', 'Attitude of friends' and 'Support of immediate family'. One item was reported as an environmental barrier - 'Societal attitudes'. The ICF-CY can be used to highlight common profiles of functioning, activities, participation and environment shared by children in relation to oral health, despite widely differing medical, social and geographical contexts. The results of this empirical

    Full Text Available This study aims to determine the effect on the quality of experience and accountability of internal audit. Supervision over the local government carried out gradually from district city level provincial level up to the Independent. in this study is the experience and accountability. While the dependent variable in this study is the quality of internal audit. it is based on several studies literature and the results of previous research studies the results of this study show that the experience and accountability have a very strong role in determining the quality of internal audit and if someone does the same job repeatedly or continuously it will be more faster and more professional work in completing the internal audit well this is because the auditor has to really understand the technique or how to complete the audit properly and be careful in completing the audit as expected therefore experience of auditors and internal auditors to perform the audit can improve the quality of internal audit.

    The Sahara desert is notorious as a source of massive dust storms. This dust dramatically influences the Earth-atmosphere energy budget through reflecting and absorbing the incoming sunlight. However, this budget is poorly understood, and in particular, we lack quantitative understanding of how the diurnal and seasonal variation of meteorological variables and aerosol properties influence the propagation of solar irradiance through the desert atmosphere. To improve our understanding of these influences, coincident and collocated observations of fluxes, measured from both space and the surface, are highly desirable. Recently, the unique capabilities of the African Monsoon Multidisciplinary Analysis (AMMA) Experiment, the Atmospheric Radiation Measurement (ARM) Mobile Facility (AMF), the Geostationary Earth Radiation Budget (GERB) instrument, and the Spinning Enhanced Visible and Infrared Imager (SEVIRI) were combined effectively as part of a large international project: the Radiative Atmospheric Divergence using AMF, GERB data and AMMA Stations (RADAGAST), which took place in Niamey, Niger, in 2006. The RADAGAST objectives, instrumentation, and scientific background are presented in [1]. Initial results from RADAGAST documented the strong radiative impact of a major Saharan dust storm on the Earth’s radiation budget [2]. A special issue of the Journal of Geophysical Research will include a collection of papers with the more complete results from RADAGAST (e.g., [1,3], and references therein). In particular, a year-long time series from RADAGAST are used to investigate (i) the factors that control the radiative fluxes and the divergence of radiation across the atmosphere [3-5], (ii) seasonal changes in the surface energy balance and associated variations in atmospheric constituents (water vapor, clouds, aerosols) [6], and (iii) sensitivity of microphysical, chemical and optical properties of aerosols to their sources and the atmospheric conditions [7].

    International or foreign students are those who enrol in universities outside their country of citizenship. They face many challenges acculturating to and learning in a new country and education system, particularly if they study in an additional language. This qualitative inquiry aimed to explore the learning and acculturating experiences of international nursing students to identify opportunities for teaching innovation to optimise the experiences and learning of international nursing students. Undergraduate and postgraduate international nursing students were recruited from one campus of an Australian university to take part in semi-structured interviews. A purposive and theoretically saturated sample of 17 students was obtained. Interviews were audio-recorded and field notes and interview data were thematically analysed. Expressing myself and Finding my place were the two major themes identified from the international student data. International nursing students identified that it took them longer to study in comparison with domestic students and that stress negatively influenced communication, particularly in the clinical setting. Additionally international nursing students identified the need to find supportive opportunities to speak English to develop proficiency. Clinical placement presented the opportunity to speak English and raised the risk of being identified as lacking language proficiency or being clinically unsafe. Initially, international nursing students felt isolated and it was some time before they found their feet. In this time, they experienced otherness and discrimination. International nursing students need a safe place to learn so they can adjust and thrive in the university learning community. Faculty and clinical educators must be culturally competent; they need to understand international nursing students' needs and be willing and able to advocate for and create an equitable environment that is appropriate for international nursing

Bess Idaho National Laboratory Jim Gulliford, Tatiana Ivanova Nuclear Energy Agency of the Organisation for Economic Cooperation and Development E.V.Rozhikhin, M.Yu.Sem?nov, A.M.Tsibulya Institute of Physics and Power Engineering The study the physics of fast reactors traditionally used the experiments presented in the manual labor of the Working Group on Evaluation of sections CSEWG (ENDF-202) issued by the Brookhaven National Laboratory in 1974. This handbook presents simplified homogeneous model experiments with relevant experimental data, as amended. The Nuclear Energy Agency of the Organization for Economic Cooperation and Development coordinates the activities of two international projects on the collection, evaluation and documentation of experimental data - the International Project on the assessment of critical experiments (1994) and the International Project on the assessment of reactor experiments (since 2005). The result of the activities of these projects are replenished every year, an international directory of critical (ICSBEP Handbook) and reactor (IRPhEP Handbook) experiments. The handbooks present detailed models of experiments with minimal amendments. Such models are of particular interest in terms of the settlements modern programs. The directories contain a large number of experiments which are suitable for the study of physics of fast reactors. Many of these experiments were performed at specialized critical stands, such as BFS (Russia), ZPR and ZPPR (USA), the ZEBRA (UK) and the experimental reactor JOYO (Japan), FFTF (USA). Other experiments, such as compact metal assembly, is also of interest in terms of the physics of fast reactors, they have been carried out on the universal critical stands in Russian institutes (VNIITF and VNIIEF) and the US (LANL, LLNL, and others.).

  19. Sustaining liminality: Experiences and negotiations of international females in U.S. engineering graduate programs

    Science.gov (United States)

    Dutta, Debalina

    This project examines the intersectionalities of international females in engineering graduate programs of the United States, using frameworks of sustainability and liminality theory. According to Dutta and Kisselburgh (2011) international females in graduate engineering constitute the minorities of minorities, not only in terms of their status as international students but also by their underrepresentation as women in engineering (Faulkner, 2009). Research regarding international female graduate students tends to be categorized as the experiences of international students in the U.S. (Lee & Rice, 2007), or as the struggles of female engineers in engineering disciplines (Tonso, 2007). Therefore, this project aims to distinguish the unique population of female engineers of international origin from holistic studies of international students, and attempts to draw out and understand the experiences of international female students in U.S. engineering graduate programs. Dutta and Kisselburgh (2011) found that female engineers who are international in origin exist in liminal states indefinitely. This liminal nature has been described under the theory of liminality (Turner, 1967) which posits that when transitioning from one life-changing event to another (such as birth, death, marriage), individuals go through a transformatory phase where they are subjected to invisibility, vulnerability, and a feeling of loss. Although Turner posited this phase as transcendental and temporary, Dutta and Kisselburgh (2011) suggest the liminal period can be more permanent in contemporary global societies. In other words, liminal experiences of vulnerability and structural invisibility may be sustained experiences of international female engineering students. Furthermore, the project attends to the overlaps, tensions and challenging experiences faced by international females in surviving engineering graduate program. To achieve this goal, liminality theory is limited in accounting for how

    Health professional education programs attract students from around the world and clinical supervisors frequently report that international students find learning in clinical placement contexts particularly challenging. In existing literature clinical supervisors, who support international students on placement have identified concerns about their communication and interactions within clinical environments. However, clinical supervisors' perspectives about their experiences with international students on placement and the strategies they utilise to facilitate international student learning have not been described. As a result we have little insight into the nature of these concerns and what clinical supervisors do to support international students' competency development. Five focus group interviews were conducted with twenty Speech-Language Pathology clinical supervisors, recruited from 2 Australian universities. Interview data were analysed thematically. Themes identified were interpreted using cognitive load and sociocultural learning theories to enhance understanding of the findings. Four themes were identified: 'Complex teaching and learning relationships', 'Conceptions of students as learners'; Student communication skills for professional practice', and 'Positive mutual learning relationships'. Findings indicated that clinical supervisors felt positive about supporting international students in clinical placements and experienced mutual learning benefits. However, they also identified factors inherent to international students and the placement environment that added to workload, and made facilitating student learning complex. Clinical supervisors described strategies they used to support international students' cultural adjustment and learning, but communication skills were reported to be difficult to facilitate within the constraints of placements. Future research should address the urgent need to develop and test strategies for improving international

    International student enrolment in Canadian universities is increasing. As international university students acculturate, they experience a culture shock in which food plays a major role. International university students' Canadian food experiences therefore were explored. A Photovoice methodology was used with 15 international undergraduate and graduate university students, who were recruited to take pictures of their food experiences. They also participated in two focus group discussions that included an analysis of their photos. Seven themes related to the significance of food in acculturation were revealed: the paradox of Canadian convenience, the equation of traditional foods with health, traditional food quality and accessibility, support networks, food consumption for comfort, ethnic restaurants, and the exploration of non-traditional foods. Maintaining cultural identity with traditional foods was an overarching theme related to acculturation. International students acculturating to Canada have emotional and physical needs, which can be met through food. Opportunities exist to improve their acculturation experiences. Canadian universities can incorporate food acculturation strategies into campus events and menus. Nutrition professionals on campus can facilitate a positive food environment and nurture culture identity formation.

    Participating in global health care through international clinical education may enhance the development of cultural competence and professionalism. Many logistical issues need to be resolved in the development of international clinical education experiences that meet program requirements. The purpose of this case report is to describe how a university developed such an experience for students by partnering with Amizade Global Service-Learning (Amizade), an organization that facilitates global learning experiences. Medical, nursing, and pharmacy students were already participating in a 4-week international health-related service learning rotation through Amizade. The preexisting relationship and contractual agreement with the university provided the necessary legal framework. Amizade staff assisted in finding a physical therapist qualified and willing to host a student. The academic coordinator for clinical education at the university and Amizade liaisons determined living arrangements, schedule, clinical settings, and patient population. The selected student had expressed interest and had met all clinical education placement requirements. The academic coordinator for clinical education had ongoing electronic communications with all parties. The student demonstrated predicted attributes of cultural competence and professionalism; through the partnership with Amizade, the student was exposed to several unique interprofessional experiences. The steps used by the university faculty in developing this interprofessional, international clinical education experience through a collaborative partnership may provide guidance for other institutions. © 2017 American Physical Therapy Association

    From a commercial supplier a solution containing 134 Cs has been standardized at National Laboratory for Ionizing Radiation Metrology (LNMRI) for the first time using three Liquid scintillation based measurement. These measurement methods are 4πβ-γ live-timed anticoincidence counting, 4πβ-γ coincidence counting and 3 H-standard efficiency tracing with the CNET methods. The results obtained by anticoincidence counting was adopted as reference value and its combined uncertainty was 0.38%. The agreement of this reference value with coincidence counting and CNET methods were 0.39% and 0.34% respectively and were in consistency with each uncertainty method. The weighted mean results coincidence counting and CNET methods are also in close agreement 0.03% with anticoincidence counting method and meets the requirement of primary and national standard. This standardization was made in order to reduce the uncertainty in 134 Cs measurement in Brazil and also following a request made by Bureau International des Poids and Mesures for new submission to International Reference System. The LNMRI last submission was made in 1987. Therefore from a 134 Cs master solution a NIST ampoules was prepared and LNMRI/IRD submitted it to the International Reference System, Bureau International of Poids and Measures (SIR/BIPM). In this paper will be analyzed the LNMRI measurement and performance each measurement methods and also take into account the reference value of KCDB, we determined also the 134 Cs gamma emission probabilities of main energy.

    Globalisation has brought new possibilities for international growth in education and professional mobility among healthcare professionals. There has been a noticeable increase of international degree programmes in non-English speaking countries in Europe, creating clinical learning challenges for healthcare students. The aim of this systematic review was to describe mentors' experiences of international healthcare students' learning in a clinical environment. The objective of the review was to identify what influences the success or failure of mentoring international healthcare students when learning in the clinical environment, with the ultimate aim being to promote optimal mentoring practice. A systematic review was conducted according to the guidelines of the Centre for Reviews and Dissemination. Seven electronic databases were used to search for the published results of previous research: CINAHL, Medline Ovid, Scopus, the Web of Science, Academic Search Premiere, Eric, and the Cochrane Library. Search inclusion criteria were planned in the PICOS review format by including peer-reviewed articles published in any language between 2000 and 2014. Five peer-reviewed articles remained after the screening process. The results of the original studies were analysed using a thematic synthesis. The results indicate that a positive intercultural mentor enhanced reciprocal learning by improving the experience of international healthcare students and reducing stress in the clinical environment. Integrating international healthcare students into work with domestic students was seen to be important for reciprocal learning and the avoidance of discrimination. Many healthcare students were found to share similar experiences of mentoring and learning irrespective of their cultural background. However, the role of a positive intercultural mentor was found to make a significant difference for international students: such mentors advocated and mediated cultural differences and

    Introduction: Interns' experiences communicating with and writing referrals to hospital radiology departments are important for patient safety, image quality, and decision-making in the diagnostic process. Understanding roles within the department and in the diagnostic process is important for communication. This study aimed to describe interns' experiences communicating with and writing referrals to their hospital's radiology department. Method: A qualitative study design was used. Data was collected from focus discussions with ten interns in three focus groups in Northern Sweden during 2012. The data were subjected to qualitative content analysis. Results: One theme, “a feeling of being scrutinized and lacking control”, was identified in the final categories. The interns experienced that the radiology department placed high demands on them and desired more diagnostic skills training, resources and feedback. The interns suggested the following improvements: enhanced dialogue and feedback, improved education, handy guidelines, and practice writing referrals. Conclusion: Interns need more feedback from, and dialogue with, members of the Department of Radiology. They also need more knowledge of referral guidelines, appropriateness criteria and more practice to develop their knowledge and skill for writing referrals. They describe feelings of inadequate support and feel scrutinized in demanding work conditions and need more collaboration. They also need more time and more control of radiology outcomes, and they are eager to learn. - Highlights: • Interns' experiences of writing referrals are important in the diagnostic process. • Communication between referents and radiology staff influences patient safety. • Medical interns experience insufficient diagnostic skills. • Interns need more feedback from, and dialogue with radiology staff. • The learning process could benefit from knowledge of the referrers perspective.

    Yozwiak, John A; Robiner, William N; Victor, Andrea M; Durmusoglu, Gokce

    2010-09-01

    This article reviews the use and perceptions of videoconferencing in psychology internship training from the perspective of interns. Videoconferencing offers a means of expanding training beyond conventional on-site models. Psychology interns completed an online survey about their experiences with videoconferencing and perspectives of its impact on training. Most participants encountered it in their didactics. Some used it for supervision or other purposes. Interns' perspectives were complex, with videoconferencing seen as supporting learning similar to conventional training in some ways, yet as less desirable overall. Direct comparisons between videoconferencing and on-site training revealed interns perceived videoconferencing as somewhat less effective, and as deleteriously affecting learning dynamics. Challenges and potential benefits of incorporating videoconferencing into psychology internship training were identified. Potential benefits include augmenting available internship training and increasing rural sites' access to training.

    2002-01-01

    Equatorial Energy Inc. is a small Canadian company that has succeeded in the international world of oil exploration and production. The 5 year old company has grown from zero to 13,000 boe/d through its engagement in the acquisition, exploration and development of petroleum and natural gas in Western Canada and Indonesia. Finding costs are getting higher as domestic sedimentary basins mature. This results in higher decline rates and fewer opportunities for growth. However, the international energy sector has become more accessible to small- and medium-sized companies due to the removal of political barriers and better access to new technologies. The support of capital markets and international experience also contributes to greater success in accessing the international energy sector. 16 figs

    2013-02-01

    This study compares the Center for Disease Control (CDC) and International Obesity Task Force (IOTF) references in assessment of overweight and obesity among Iranian adolescents. The data of this study was drawn from a cross sectional study of a representative sample of 1200 adolescents aged 12-17 years in Babol, northern Iran. A standard procedure was used to measure height and weight and the body mass index was calculated. Each subject was classified as overweight and obese based on IOTF cut off values of BMI and CDC references BMI percentile sets by age and sex. The kappa coefficients were estimated for the degree of agreement. In assessment of obesity/overweight prevalence, the CDC and IOTF references produced a similar estimate by age group and sex. The maximum differences was about 1% and the kappa coefficients was 0.96 to 1 (P = 0.001). While for assessment of obesity, the CDC reference produced slightly a higher rate of obesity and the difference in prevalence between the two sets of references was ranged from 1.4% to 3.2% with kappa coefficients: 0.90 to 0.70 (P = 0.001) depending on the age group and sex and a greater difference was observed among younger age group. The findings suggest an excellent agreement between the TOTF and CDC references in assessment of overall overweight/obesity prevalence among adolescent boys and girls. While in assessment of obesity prevalence alone the degree of agreement between the two sets of references slightly diminished. Overall, the two references are comparable and the agreement varies a little with respect to age and sex.

    2015-06-01

    This study aims to compare three body mass index (BMI)-based classification systems of childhood obesity: the French, the International Obesity Task Force (IOTF) and the World Health Organization (WHO) references. The study involved 1382 schoolchildren, recruited from the Lille Academic District in France in May 2009 aged 8.4±1.7 years (4.0-12.0 years). Their mean height and body mass were 131.5±10.9cm and 30.7±9.2kg, respectively, resulting in a BMI of 17.4±3.2kg/m(2). The weight status was defined according to the three systems considered in this study. The agreement between these references was tested using the Cohen's kappa coefficient. The prevalence of overweight was higher with the WHO references (20.0%) in comparison with the French references (13.8%; Preferences: 6.7%; Preferences ranged from "moderate" to "perfect" (0.43≤κ≤1.00; Preferences were used to classify children as obese (0.63≤κ≤1.00; Preferences in boys aged 7-12 years (κ=0.28; Preferences and IOTF (κ=0.97; Preferences ranged from 0.60 to 1.00 (Preferences against French references or IOTF among boys aged 7-12 years (κ=0.60; Preferences yield an overestimation in overweight and/or obesity within this sample of schoolchildren as compared to the French references and the IOTF. The magnitude of agreement coefficients between the three references depends on of both sex and age categories. The French references seem to be in rather close agreement with the IOTF in defining overweight, especially in 7-12-year-old children. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

    Children in dentistry are traditionally described in terms of medical diagnosis and prevalence of oral disease. This approach gives little information regarding a child’s capacity to maintain oral health or regarding the social determinants of oral health. The biopsychosocial approach, embodied in the International Classification of Functioning, Disability and Health - Child and Youth version (ICF-CY) (WHO), provides a wider picture of a child’s real-life experience, but practical tools for the application of this model are lacking. This article describes the preliminary empirical study necessary for development of such a tool - an ICF-CY Core Set for Oral Health. An ICF-CY questionnaire was used to identify the medical, functional, social and environmental context of 218 children and adolescents referred to special care or paediatric dental services in France, Sweden, Argentina and Ireland (mean age 8 years ±3.6yrs). International Classification of Disease (ICD-10) diagnoses included disorders of the nervous system (26.1%), Down syndrome (22.0%), mental retardation (17.0%), autistic disorders (16.1%), and dental anxiety alone (11.0%). The most frequently impaired items in the ICF Body functions domain were ‘Intellectual functions’, ‘High-level cognitive functions’, and ‘Attention functions’. In the Activities and Participation domain, participation restriction was frequently reported for 25 items including ‘Handling stress’, ‘Caring for body parts’, ‘Looking after one’s health’ and ‘Speaking’. In the Environment domain, facilitating items included ‘Support of friends’, ‘Attitude of friends’ and ‘Support of immediate family’. One item was reported as an environmental barrier – ‘Societal attitudes’. The ICF-CY can be used to highlight common profiles of functioning, activities, participation and environment shared by children in relation to oral health, despite widely differing medical, social and geographical

    2008-01-01

    1 - Description: The purpose of the International Reactor Physics Experiment Evaluation Project (IRPhEP) is to provide an extensively peer-reviewed set of reactor physics-related integral data that can be used by reactor designers and safety analysts to validate the analytical tools used to design next-generation reactors and establish the safety basis for operation of these reactors. This work of the IRPhEP is formally documented in the 'International Handbook of Evaluated Reactor Physics Benchmark Experiments,' a single source of verified and extensively peer-reviewed reactor physics benchmark measurements data. The IRPhE Handbook is available on DVD. You may request a DVD by completing the DVD Request Form available at: http://irphep.inl.gov/handbook/hbrequest.shtml The evaluation process entails the following steps: 1. Identify a comprehensive set of reactor physics experimental measurements data, 2. Evaluate the data and quantify overall uncertainties through various types of sensitivity analysis to the extent possible, verify the data by reviewing original and subsequently revised documentation, and by talking with the experimenters or individuals who are familiar with the experimental facility, 3. Compile the data into a standardized format, 4. Perform calculations of each experiment with standard reactor physics codes where it would add information, 5. Formally document the work into a single source of verified and peer reviewed reactor physics benchmark measurements data. The International Handbook of Evaluated Reactor Physics Benchmark Experiments contains reactor physics benchmark specifications that have been derived from experiments that were performed at various nuclear experimental facilities around the world. The benchmark specifications are intended for use by reactor physics personal to validate calculational techniques. The 2008 Edition of the International Handbook of Evaluated Reactor Physics Experiments contains data from 25 different

    Attrill, Stacie; Lincoln, Michelle; McAllister, Sue

    2015-06-01

    This study aimed to describe perceptions of clinical placement experiences and competency development for international speech-language pathology students and to determine if these perceptions were different for domestic students. Domestic and international students at two Australian universities participated in nine focus group interviews. Thematic analysis led to the identification of two themes shared by international and domestic students and several separate themes. Shared themes identified the important influence of students' relationships with clinical educators, unique opportunities and learning that occurs on placement. International student themes included concerns about their communication skills and the impact of these skills on client progress. They also explored their adjustment to unfamiliar placement settings and relationships, preferring structured placements to assist this adjustment. Domestic student themes explored the critical nature of competency attainment and assessment on placement, valuing placements that enabled them to achieve their goals. The findings of this study suggest that international students experience additional communication, cultural and contextual demands on clinical placement, which may increase their learning requirements. Clinical education practices must be responsive to the learning needs of diverse student populations. Strategies are suggested to assist all students to adjust to the professional and learning expectations of clinical education placements.

  12. Warnings on alcohol containers and advertisements: international experience and evidence on effects.

    Wilkinson, Claire; Room, Robin

    2009-07-01

    In light of possible introduction of alcohol warning labels in Australia and New Zealand, this paper discusses the international experience with and evidence of effects of alcohol warning labels. The report describes international experience with providing information and warnings concerning the promotion or sale of alcoholic beverages, and considers the evidence on the effects of such information and warnings. The experience with and evaluations of the effects of tobacco warning labels are also considered. The most methodologically sound evaluations of alcohol warning labels are based on the US experience. Although these evaluations find little evidence that the introduction of the warning label in the USA had an impact on drinking behaviour, there is evidence that they led to an increase in awareness of the message they contained. In contrast, evaluations of tobacco warning labels find clear evidence of effects on behaviour. There is a need and opportunity for a rigorous evaluation of the impacts of introducing alcohol warning labels to add to the published work on their effectiveness. The experience with tobacco labels might guide the way for more effective alcohol warning labels. Alcohol warning labels are an increasingly popular alcohol policy initiative. It is clear that warning labels can be ineffective, but the tobacco experience suggests that effective warning labels are possible. Any introduction of alcohol warning labels should be evaluated in terms of effects on attitudes and behaviour.

    Monitoring a child's growth status helps to diagnose diseases and implement curative and preventive measures. The aim of this study was to assess how well preschool children of Russian city (Nizhny Novgorod) match with, or diverge from, international growth charts (WHO2006,2007; USCDC2000). Cross-sectional study included 3,130 children aged 3-7 years attending municipal preschools of Nizhny Novgorod, the city in the European part of Russia. The study was held from February 2012 to October 2013. The international WHO2006,2007 and USCDC2000 growth references were used to calculate the height, weight and BMI z-scores. The distributions of z-scores were analysed with descriptive and inferential statistical methods. Z-score equal 0.25 was considered as a benchmark for clinically significant differences. Means height z-scores calculated with the use of WHO2006, 2007 and USCDC2000 references were above the 50th centile (0.13 - 0.47) for both boys and girls. The means height z-scores was less than 0.25 SD above the 50th centile only for WHO2006. Stunting prevalence (the height-for-age z-score less than -2) was slightly higher under WHO2006 (3-4%) than under USCDC 2000 (2-3%). Stunting prevalence among children aged 5-7 years was similar under WHO2007 and USCDC2000 references (1%).

    The Alpha Magnetic Spectrometer (AMS) is a detector designed to operate in space to search for antimatter components in cosmic ray, the annihilation products of darkmatter and to study the antiprotons, positrons and light nuclei. A 'baseline' version of the experiment has successfully completed the precursor flight on Space Shuttle Discovery (June 2-12, 1998). The complete AMS is programmed for installation on International Space Station in year 2003 for an operational period of 3 years. In this contribution we report on the experimental configuration of AMS that will be installed on International Space Station.

  15. International student nurses' experiences of clinical practice in the Finnish health care system.

    2010-05-01

    The purpose of this qualitative study was to describe international student nurses' experiences of their clinical practice in the Finnish health care system. The data were collected by semi-structured interviews. Fourteen international student nurses of African and Asian origin were interviewed, and the data were then analysed by qualitative content analysis. The results indicated that appreciative orientation, sense of belonging to the team, enhancing independent working, growing towards professionalism and working as a member of the team were descriptions of positive experiences. Descriptions of negative experiences were related to restricted learning and compromised human dignity, which lead to negative feelings of being an outsider, decreased self-esteem, sense of giving up and anticipation of difficulties. Despite the small sample size, the results indicate a need to develop clinical practice arrangements when the language of the learning environment is other than that of the student nurse. As the number of international students has increased in the Finnish health care sector and in nursing education, it is important to recognise the factors related to positive and negative experiences in clinical practice.

    International students from culturally and linguistically diverse backgrounds experience personal and academic challenges when studying health sciences in Australia. Given recent discussions about cultural specificity in occupational therapy and its status as an emerging profession in most Asian countries, this study aimed to explore and describe the experiences of international students from Asian backgrounds studying occupational therapy in Australia. A phenomenological approach was used to understand the experiences of participants. In-depth interviews were conducted with eight international occupational therapy students from Asian countries studying in Australia. Data were analysed using hermeneutic methods. Participants described three interlinked and ongoing experiences: (1) Discovering and engaging with occupational therapy; (2) Fitting into my new role; and (3) Anticipating my role at home. Whilst theoretical aspects of occupational therapy were seen as compatible with participants' home cultures, application was seen as problematic due to the differences in structure and institutional culture of the healthcare systems. Although students made adaptations to fit in as occupational therapy students in Australia, they continued to see themselves as different, and their adaptation also influenced how they saw themselves in relation to their home culture. Findings can contribute to creating culturally sensitive education for occupational therapy students from Asian countries. To best serve these students, educators should consider ways to facilitate transitions both out of and back into students' home cultures. © 2016 Occupational Therapy Australia.

  17. Interpreting Fuzzy Linguistic Information by Acquiring Robot's Experience Based on Internal Rehearsal

    Science.gov (United States)

    Jayasekara, A. G. Buddhika P.; Watanabe, Keigo; Kiguchi, Kazuo; Izumi, Kiyotaka

    This paper proposes a method for interpreting fuzzy linguistic information by acquiring robot's experience on previous movements. The quantitative assessment for a fuzzy linguistic term such as “little” depends on the spatial arrangement of surrounding environment. Robot's experience on previous movements is very useful for understanding such information in a context dependant manner. Therefore, an internal rehearsal system is introduced to acquire the robot's experience on previous movements. Such acquisition enhances the robot's capability to interpret fuzzy linguistic information in fuzzy voice commands (FVCs) according to the current environmental context. The proposed system is used to evaluate the fuzzy linguistic information related to primitive movements of a robot manipulator. Those primitive movements are realized by a behavior evaluation network (BEN) with the guidance of an internal rehearsal system. The end-effector movements and the single joint movements of a robot manipulator are considered as primitive movements. They are activated by fuzzy voice motion commands (FVMCs) and fuzzy voice joint commands (FVJCs) respectively. The proposed idea is demonstrated with a PA-10 robot manipulator by navigating the robot manipulator in the user's working space. The use of the behavior evaluation network and the internal rehearsal system introduced a better way of assessing fuzzy linguistic information by acquiring the robot's experience on the corresponding environment.

    Full Text Available This paper investigates contemporary approaches defined by the policies, programs or standards that favor green infrastructure in urban planning for cooling urban environments with special reference to Serbian experiences. The research results reveal an increasing emphasis on the multifunctionality of green infrastructure as well the determination to the development of policies, guidelines and standards with the support of the overall community. Further, special importance is given to policies that promote ‘cool communities’ strategies resulting in the increase of vegetation-covered areas, what has contributed in adapting urban environments to the impacts of climate change. In addition, this research indicates the important role of local authorities and planners in Serbia in promoting planning policies and programs that take into consideration the role of green infrastructure in terms of improving climatic conditions, quality of life and reducing energy needed for cooling and heating.

    1991-01-01

    In support of a continuing program of systematic evaluation of nuclear structure data, the National Nuclear Data Center maintains a complete computer file of references to the nuclear physics literature. Each reference is tagged by a keyword string, which indicates the kinds of data contained in the article. This master file of Nuclear Structure References (NSR) contains complete keyword indexes to literature published since 1969, with partial indexing of older references. Any reader who finds errors in the keyword descriptions is urged to report them to the National Nuclear Data Center so that the master NSR file can be corrected. In 1966, the first collection of Recent References was published as a separate issue of Nuclear Data Sheets. Every four months since 1970, a similar indexed bibliography to new nuclear experiments has been prepared from additions to the NSR file and published. Beginning in 1978, Recent References was cumulated annually, with the third issue completely superseding the two issues previously published during a given year. Due to publication policy changes, cumulation of Recent Reference was discontinued in 1986. The volume and issue number of all the cumulative issues published to date are given. NNDC will continue to respond to individual requests for special bibliographies on nuclear physics topics, in addition to those easily obtained from Recent References. If the required information is available from the keyword string, a reference list can be prepared automatically from the computer files. This service can be provided on request, in exchange for the timely communication of new nuclear physics results (e.g., preprints). A current copy of the NSR file may also be obtained in a standard format on magnetic tape from NNDC. Requests for special searches of the NSR file may also be directed to the National Nuclear Data Center

    2010-10-01

    This review explores the experiences of international nurses recently recruited to the UK nursing workforce (1995-2007) and the implications for retention. An acute shortage of nurses in the mid 1990s, combined with policy initiatives to increase the number of qualified nurses working in the NHS, resulted in an active campaign to recruit nurses from overseas. Since 1997, approximately 100,000 international nurses have been admitted to the nursing register from more than 50 countries worldwide. Many practice areas are now dependent on overseas nurses as an essential part of their workforce. An integrative review. The review was conducted using a range of electronic databases to capture the experiences of this cohort of migrant nurses. Much literature has been generated over the past decade in relation to the experiences of international nurses recruited during this campaign. Five main themes emerged from the review: motivation for migration, adapting to British nursing, experiences of first world healthcare, feeling devalued and deskilled and vectors of racial discrimination. Although some positive experiences are described, significant numbers of nurses describe not feeling personally or professionally valued by the UK nursing establishment, common emotions expressed are disappointment and unmet expectations. This will have implications for job satisfaction and intention to leave or stay. If overseas nurses choose to leave the UK in large numbers, the health services could face a severe staffing shortage. It is important that we listen carefully to their experiences to help identify priorities for policy and practice aimed at improving job satisfaction for migrant nurses and articulating the value that they bring to UK nursing. © 2010 Blackwell Publishing Ltd.

    An experiment was performed which confirms the existence of an internal mode dependence of molecular sticking probabilities for collisions of molecules with a cold surface. The scattering of a velocity selected effusive beam of CCl{sub 4} from a 90 K CC1{sub 4} ice surface has been studied at five translational velocities and for two different internal temperatures. At a surface temperature of 90 K (approx. 99% sticking probability) a four fold increase in reflected intensity was observed for the internally excited (560 K) CC1{sub 4} relative to the room temperature (298 K) CC1{sub 4} at a translational velocity of 2.5 X 10{sup 4} cm/sec. For a surface temperature of 90 K all angular distributions were found to peak 15{sup 0} superspecularly independent of incident velocity.

  3. Competition in electricity markets: international experience and the case of Italy

    As a result of European Directives 96/92 and 2003/54 on the liberalisation of the internal market for electricity, the Italian electricity sector has been subject to extensive institutional changes which have affected the competitive nature of the market. In this paper we attempt to assess the likely effect of these institutional changes on the Italian electricity industry, and focus particularly on the impact of the introduction of a centralised wholesale market. The assessment of the likely impact of these institutional changes is based on the comparison with the international experience of countries where extensive liberalisation measures have been implemented (such as the US, UK and the Scandinavian region). On the basis of this international comparison, we draw some lessons about how to promote effective competition in the Italian market and in other electricity markets which have not been fully liberalised.

    prevalencia de retraso del crecimiento.OBJECTIVE: To evaluate if using an international growth reference versus a national growth reference leads to differences in the prevalences of low weight-for-height (wasting and low height-for-age (stunting in a sample of children 8 to 14 years old. METHODS: A cross-sectional study was carried out with a sample of 1 470 school-children (both boys and girls in the city of La Plata, in the province of Buenos Aires, Argentina. Based on the data on weight and height, Z-scores were calculated with regard to the reference values from the United States of America's first and second National Health and Nutrition Examination Survey (NHANES I and NHANES II, and the reference values for Argentina from the Argentine Pediatric Society. The prevalences of wasting and stunting were calculated, using as the cutoff point two standard deviations below the median of the reference. The prevalences were compared using the chi-squared test with Yates' correction, and odds ratios (ORs and 95% confidence intervals (95% CIs were calculated. RESULTS: The international reference was positively associated with a higher prevalence of stunting in the entire sample (OR = 5.12; 95% CI: 3.27 to 8.05, in the boys (OR = 4.36; 95% CI: 2.43 to 7.93, and in the girls (OR = 6.32; 95% CI: 3.10 to 13.27. The prevalence of wasting was similar with both references. The distribution of height-for-age was skewed to the left with respect to the international reference and to the right with respect to the Argentine reference, while the distribution of weight-for-height overlapped both references. CONCLUSIONS: The differences in the prevalences of stunting calculated according to the two references that were used indicate a different nutritional status for the population studied. The increase in the height of the children with respect to the Argentine reference points to the presence of a positive secular trend, and the increase can explain part of the differences in the prevalence

    We investigated differential patterns of hallucinatory experiences between nonclinical and clinical samples. A total of 223 nonclinical individuals (108 females) and 111 subjects with schizophrenia (54 females) completed the Launay-Slade Hallucination Scale-Revised (LSHS-R) and Perceptual Aberration Scale (PAS). The Minnesota Multiphasic Personality Inventory-2 (MMPI-2) was used for the nonclinical group, and the Positive and Negative Syndrome Scale (PANSS) hallucination item was used for the clinical group. Cronbach's alpha values showed good internal consistency for the LSHS-R. In the two groups, significant associations were found between LSHS-R and PAS scores. Two factors were extracted through a principal component analysis (PCA) in the nonclinical group, and three factors were identified in the clinical group. The results of a hierarchical cluster analysis (HCA) revealed that a perception-cognition dimension was clear cluster discriminating element for the nonclinical group, whereas alterations in perception-cognition dimension were characteristic in cluster structure of the clinical group. Our findings suggest that the nature of hallucinatory experiences may differ qualitatively between a nonclinical population and subjects with schizophrenia. Perceptual or cognitive aberrations may add a psychopathologic dimension to hallucinatory experiences. Exploring the internal structure of hallucinatory experiences may provide explanatory insight into these experiences in the general population. Copyright © 2015 Elsevier Ireland Ltd.

    The Stratospheric Aerosol and Gas Experiment III on the International Space Station (SAGE III/ISS) mission will extend the SAGE data record from the ideal vantage point of the International Space Station (ISS). The ISS orbital inclination is ideal for SAGE measurements providing coverage between 70 deg north and 70 deg south latitude. The SAGE data record includes an extensively validated data set including aerosol optical depth data dating to the Stratospheric Aerosol Measurement (SAM) experiments in 1975 and 1978 and stratospheric ozone profile data dating to the Stratospheric Aerosol and Gas Experiment (SAGE) in 1979. These and subsequent data records, notably from the SAGE II experiment launched on the Earth Radiation Budget Satellite in 1984 and the SAGE III experiment launched on the Russian Meteor-3M satellite in 2001, have supported a robust, long-term assessment of key atmospheric constituents. These scientific measurements provide the basis for the analysis of five of the nine critical constituents (aerosols, ozone (O3), nitrogen dioxide (NO2), water vapor (H2O), and air density using O2) identified in the U.S. National Plan for Stratospheric Monitoring. SAGE III on ISS was originally scheduled to fly on the ISS in the same timeframe as the Meteor-3M mission, but was postponed due to delays in ISS construction. The project was re-established in 2009.

    The Canadian market has a number of potential applications for small modular reactors in industries such as mining, oil and gas, and defense where power demand is often in remote locations not easily serviced by the electrical grid. Since Canada has a long history of nuclear power regulation (including small reactors) and has developed regulatory documents for small reactors, there is high potential for SMRs to be successfully licensed, designed, built, and operated. This paper summarized Canadian and International experience with small reactors. It also summarizes safety and licensing considerations from this experience. (author)

    Accurate air mass zero (AM0) measurement is essential for the evaluation of new photovoltaic (PV) technology for space solar cells. The NASA Glenn Research Center (GRC) has flown an experiment designed to measure the electrical performance of several solar cells onboard NASA Goddard Space Flight Center's (GSFC) Robotic Refueling Missions (RRM) Task Board 4 (TB4) on the exterior of the International Space Station (ISS). Four industry and government partners provided advanced PV devices for measurement and orbital environment testing. The experiment was positioned on the exterior of the station for approximately eight months, and was completely self-contained, providing its own power and internal data storage. Several new cell technologies including four-junction (4J) Inverted Metamorphic Multi-junction (IMM) cells were evaluated and the results will be compared to ground-based measurement methods.

    The utilization of two WHO reference materials, liquid and lyophilized, permitted international standardization of apolipoprotein measurements. We report here the results of a collaborative study between Arcol, SFBC and SFRL in order to establish reference ranges for apo A1 and B on nine standardized systems. A population of 1027 men and women supposed healthy, 4 to 60 year old, have been selected in two Centers for Preventive Medicine. The serum samples were aliquoted frozen at -20 degrees C the day of sampling and analysed by the manufacturers with IFCC standardized calibrants. A specific quality control was performed using a frozen pool of sera. For apo A1, the centile 2.5 of the reference population varies from 1.04 to 1.16 g/l. The range values for the centile 97.5 varies from 1.87 to 2.24 g/l. For apoB, the centile 2.5 varies from 0.43 to 0.57 g/l, and the centile 97.5 from 1.30 to 1.39 g/l. Only one system has a problem of dispersion with an upper limit equal to 1.20 g/l. These results improve that international standardization allowed actually a good comparability of the results, especially for apoB.

    Identifying how genetic risk interacts with experience to predict psychopathology is an important step toward understanding the etiology of mental health problems. Few studies have examined genetic risk by experience interaction (G×E) in the development of childhood psychopathology. We used both co-twin and parent mental health as markers of genetic risk to test whether G×E predicted internalizing problems in a sample of 8-year-old twins. Multi-instrument composites were used to characterize both parent and child psychopathology, and five experiential risk factors (socioeconomic status, single parent upbringing, negative parent-child interactions, number of negative life events, negative impact of negative life events) composed a cumulative risk index. We found consistent evidence for G×E for child internalizing problems, with significant interaction effects emerging both when genetic risk was indexed by co-twin mental health and when it was based on parent mental health. When co-twin mental health was used to estimate genetic risk, child internalizing problems were more heritable for children at low rather than high experiential risk. When parent mental health was used to estimate genetic risk, the association between genetic risk and internalizing problems was stronger for children at elevated experiential risk. Consideration of the interaction effect sizes helps to reconcile these findings. Our results suggest that the processes involved in both diathesis-stress and bioecological models of development may operate for child internalizing problems. Effect sizes indicated that the main effects of genetic and experiential risk were much better predictors of child internalizing problems than was their interaction. © 2010 The Authors.

    The International Reporting System for Operating Experience (IRS) is an international system jointly operated by the International Atomic Energy Agency (IAEA) and the OECD Nuclear Energy Agency (OECD/NEA). The fundamental objective of the IRS is to contribute to improving the safety of commercial nuclear power plants which are operated worldwide. This objective can be achieved by providing timely and detailed information on lessons learned from operating and construction experience at the international level. This information could be related to issues and events that are related to safety. The purpose of these guidelines is to describe the system and to give users the necessary background and guidance to enable them to produce IRS reports meeting a high standard of quality while retaining the effectiveness of the system expected by all Member States operating nuclear power plants. As this system is owned by the Member States, the IRS Guidelines have been developed and approved by the IRS National Co-ordinators with the assistance of both Secretariats (IAEA/NEA).

  18. Loss of international medical experiences: knowledge, attitudes and skills at risk

    2007-11-01

    Full Text Available Background Despite the great influence International Medical Experiences (IMs can have on young physicians and their impact on patients and communities, they are not offered in all training programs and are at risk of being reduced in some due to stringent guidelines for funding of graduate medical education. Discussion IMs provide unique experiences in clinical, epidemiologic, cultural, and political arenas. From an educational perspective, they broaden a physician's differential diagnostic skills and introduce clinical entities rarely seen in the U.S. Time spent in developing countries emphasizes the importance of community health and increases cultural and linguistic competence. Experience working with the underserved during an IM has been shown to increase interest in volunteerism, humanitarian efforts, and work with underserved populations both in the US and abroad. IMs also afford physicians the opportunity to learn about the delivery of health care abroad and are associated with an increase in primary care specialty choice. Summary It is time for the leaders in graduate medical education to prioritize international health opportunities. Leaders in academic medicine can press for changes in reimbursement patterns at the national level or special funds for international electives. Hospitals can set up separate accounts to help finance resident salaries and benefits while abroad. Individual departments must be flexible with resident schedules to allow elective time. Medical students and housestaff can organize and lobby larger organizations such as the American Medical Association (AMA, the American Association of Medical Colleges (AAMC, and specialty groups to make IMs universally accessible.

    Internal friction is frequently found in protein dynamics. Its molecular origin however is difficult to conceptualize. Even unfolded and intrinsically disordered polypeptide chains exhibit signs of internal friction despite their enormous solvent accessibility. Here, we compare four polymer theories of internal friction with experimental results on the intrinsically disordered protein ACTR (activator of thyroid hormone receptor). Using nanosecond fluorescence correlation spectroscopy combined with single-molecule Förster resonance energy transfer (smFRET), we determine the time scales of the diffusive chain dynamics of ACTR at different solvent viscosities and varying degrees of compaction. Despite pronounced differences between the theories, we find that all models can capture the experimental viscosity-dependence of the chain relaxation time. In contrast, the observed slowdown upon chain collapse of ACTR is not captured by any of the theories and a mechanistic link between chain dimension and internal friction is still missing, implying that the current theories are incomplete. In addition, a discrepancy between early results on homopolymer solutions and recent single-molecule experiments on unfolded and disordered proteins suggests that internal friction is likely to be a composite phenomenon caused by a variety of processes.

    INTRODUCTION. Prevalences of overweight and obesity in students from different altitudinal zones of Jujuy are compared using the International Obesity Task Force (IOTF), the Centers for Disease Control (CDC) and the World Health Organization (WHO) references, and the agreement among them. MATERIAL AND METHODS. Weight and height data from 15 541 students were grouped in highlands (HL) (≥2500 MASL) and lowlands (LL) (references. The differences in outcome measures and prevalences were established using the ?2 test and the t test, and agreement among the criteria was calculated using the kappa index. RESULTS. Students from the HL had lower weight, height and body mass index (BMI) values (preference were higher, except for overweight in students of both sexes, from 11 to 12.99 years old, from the HL and the LL. Regardless of the references, gender and age, overweight and obesity prevalences were generally higher in the LL. Agreement between the IOTF and the CDC was good-very good, and agreement among them and the WHO was fair-moderate. CONCLUSIONS. Students from the HL had a lower overweight and obesity prevalence. The greatest agreement was observed between the IOTF and the CDC references.

    Full Text Available The growing attention placed on experiences can be regarded as a mega-trend, and has given currency to the proposition that experiences are important for consumer’s self-perception and satisfaction with a specific visit. In order to assess this assumption, this study empirically examines the applicability of Pine and Gilmore’s ‘experience economy’ concept and examines the impact of its four dimensions i.e., education, escapism, esthetics, and entertainment on delegates’ satisfaction and behavioural intentions. Based on convenience sampling, 210 questionnaires are distributed to the delegates of 2 international academic conferences out of which 188 were deemed fit for further analysis 89% response rate. The results indicate that Pine and Gilmore’s model can further our understanding of the experience market. However, the findings in contrast with previous studies show that different experiential dimensions influence the delegates’ overall satisfaction in different contexts. For instance, the dimension of education has a relatively higher significant effect on the delegates’ overall satisfaction and behavioural intentions in the context of international academic conferences. The theoretical and practical implications of this study are also discussed.

  6. Experience of International Education of East Asian Students in English-speaking Countries: A four-dimensional approach

    Full Text Available Global participation in international education in the last two decades has increased exponentially. International students face difficulties in adjusting to the culture of their host country due to their unique needs (Bertram, Poulakis, Elsasser & Kumar, 2014. This article presents themes comprising the international education phenomenon involving the experiences of East Asian international students in English-speaking countries. The literature reviewed for this article pertains to many aspects of international education, covering the factors that influence the decision to embark on the international education journey to the adjustment experienced by students to the host culture. The authors suggest that the international education experience is comprised of four dimensions: structural, linguistic, internal, and external. We also posit that Confucianism, which many East Asian students follow, influences not only the psycho-social dimension of the international education experience but also their instructional preferences within the structural dimension. We further contend that students’ actual and perceived proficiency (or the lack thereof in the host country’s language greatly shapes all aspects of the student’s international education experience, which then determines the degree of acculturative stress involved and plays a key role in each of the three dimensions. Because of the anticipated continued growth in the number of international students from East Asia attending higher education institutions in English-speaking countries such as the United States, Australia, Canada, and parts of Africa, it is important to examine how each of the dimensions proposed impact each other. Approaching the study of the international education experience one dimension at a time, as many scholars have done, does not completely address all of the unique needs of international students. We suggest that research in this area be conducted holistically by

    Globalization, along with the increasing prevalence of non-communicable diseases, their risk factors, and poor oral health, demands global approaches to oral health care. Trained health care workers' providing volunteer services abroad is one model used for improving access to dental services for some communities. Currently, little is known about U.S. dental student involvement in international clinical service volunteerism. The aim of this exploratory study was to capture national survey data from predoctoral dental students about their interest in and experience with global health service trips. The survey sought to assess students' past experiences and current and future interest in programs providing dental and/or medical services in order to lay the foundation for further research. A 12-question web-based survey was distributed in May 2017 to 22,930 students enrolled in U.S. dental schools. A total of 1,555 students responded, for a response rate of 7%. Respondents were evenly distributed across the four academic years. Approximately 22% (n=342) of the respondents had already participated in a service trip experience, 83% reported interest in a service trip while in school, and 92% were interested after graduation. Reported motivations for international trips included the desire to care for the underserved and to obtain a more global view of health and disease. Concerns were expressed regarding costs and time constraints. This study provided preliminary, exploratory data on dental student engagement with international service trips. Both interest and participation in international service trips among responding students were high, reflecting current trends in both dentistry and medicine. Dental education may have an opportunity to guide student engagement in more sustainable and ethical volunteering in the U.S. and abroad.

  8. International research and development projects in nuclear energy: Experience and future prospects

    1983-01-01

    From the very beginning nuclear energy appeared as a fruitful field for international co-operation and particularly for international projects and joint ventures. By pooling scientific, technical and financial resources, the participating countries sought to promote the development of technology and the transition of nuclear energy to the industrial stage. Governments and therefore intergovernmental organizations were the driving force behind the establishment of joint projects in various R and D sectors, often in association with industry and private research institutes. The situation changed considerably from the end of the 1960s onwards. Despite some remarkable technical achievements, international co-operation did not develop to the extent predicted at the outset. Industry took over in the exploitation of proven technologies, and industrial co-operation agreements have become an important feature in some key areas of nuclear energy. This trend raises questions as to the future of joint R and D projects organized through intergovernmental co-operation. Although such projects are still very useful, they tend to be concentrated in those few sectors which continue to be of direct interest to the Governments; for instance, fundamental research, radioactive waste management and nuclear safety. The position of nuclear energy has changed, and the benefits to be drawn from this form of international co-operation must be critically re-assessed accordingly. While advantage to be gained from international projects for countries which are the most advanced in the development of nuclear energy is not the same as it was at the beginning, the transfer of experience and knowledge to less advanced countries is still the main concern of projects dealing with safety and regulatory matters. The experience thus gained provides a very useful insight into the legal and institutional framework of joint projects

    With more than 25 years of experience in the development of reactor vessel internals segmentation and packaging technology, Westinghouse has accumulated significant know-how in the reactor dismantling market. Building on tooling concepts and cutting methodologies developed decades ago for the successful removal of nuclear fuel from the damaged Three Mile Island Unit 2 reactor (TMI-2), Westinghouse has continuously improved its approach to internals segmentation and packaging by incorporating lessons learned and best practices into each successive project. Westinghouse has developed several concepts to dismantle reactor internals based on safe and reliable techniques, including plasma arc cutting (PAC), abrasive water-jet cutting (AWJC), metal disintegration machining (MDM), or mechanical cutting. Westinghouse has applied its technology to all types of reactors covering Pressurized Water Reactors (PWR's), Boiling Water Reactors (BWR's), Gas Cooled Reactors (GCR's) and sodium reactors. The primary challenges of a segmentation and packaging project are to separate the highly activated materials from the less-activated materials and package them into appropriate containers for disposal. Since space is almost always a limiting factor it is therefore important to plan and optimize the available room in the segmentation areas. The choice of the optimum cutting technology is important for a successful project implementation and depends on some specific constraints like disposal costs, project schedule, available areas or safety. Detailed 3-D modeling is the basis for tooling design and provides invaluable support in determining the optimum strategy for component cutting and disposal in waste containers, taking account of the radiological and packaging constraints. Westinghouse has also developed a variety of special handling tools, support fixtures, service bridges, water filtration systems, video-monitoring systems and customized rigging, all of which are required for a

    Research experiences for undergraduates offer training in problem solving and critical thinking via hands-on projects. The goal of the distributed Research Experience for Undergraduates (REU) Program in the Agricultural and Biological Engineering Department (ABE) at the University of Florida (UF) is to provide undergraduate students a unique opportunity to conduct research in water resources using interdisciplinary approaches, integrating research and extension, while the cohort is not co-located. The eight-week REU Program utilizes the extensive infrastructure of UF - Institute of Food and Agricultural Sciences (IFAS) through the Research and Education Centers (RECs). To provide international research and extension experience, two students were located at the International Crop Research Institute for the Semi-Arid Tropics (ICRISAT), in India. Prior to the beginning of the Program, the students worked closely with their research mentors at University of Florida and ICRISAT to develop a project plan for understanding the water quality issues in two watersheds. The students were co-located during the Orientation week at the University of Florida. During the Program, they achieved an enriching cohort experience through social networking, daily blogs, and weekly video conferences to share their research and other REU experiences. The group meetings and guest lectures are conducted via synchronously through video conferencing. The students who were distributed across Florida benefited from the research experiences of the students who were located in India, as their project progressed. They described their challenges and achievements during the group meetings and in the blogs. This model of providing integrated research and extension opportunities in hydrology where not all the REU participants are physically co-located, is unique and can be extended to other disciplines.

    To assess if the Accreditation Council for Graduate Medical Education (ACGME) case log system accurately captures operative experience of our postgraduate year 1 (PGY-1) residents. ACGME case log information was retrospectively obtained for 5 cohorts of PGY-1 residents (2011-2015) and compared to the number of operative cases captured by an institutional automated operative case report system, Surgical Access Utility System (SAUS). SAUS automatically captures all surgical team members who are listed in the operative dictation for a given case, including interns. A paired t-test analysis was used to compare number of cases coded between the 2 systems. Academic, tertiary care referral center with a large general surgery training program. PGY-1 general surgery trainees (interns) from the years 2011-2015. Forty-nine PGY-1 general surgery residents were identified over a 5-year period. Mean operative case volume per intern, per year, captured by the automated SAUS was 176.5 ± 28.1 (SD) compared to 126.3 ± 58.0 ACGME cases logged (mean difference = 50.2 cases, p log data may not accurately reflect the actual operative experience of our PGY-1 residents. If such data holds true for other general surgery training programs, the true impact of duty hour regulations on operative volume may be unclear when using the ACGME case log data. This current standard approach for using ACGME case logs as a representation of operative experience requires further scrutiny and potential revision to more accurately determine operative experience for accreditation purposes.

    We attempted to identify the risk factors that may affect mental health status of the international students and we conducted the survey using a self-administered questionnaire. Depressive symptoms were measured using the Center for Epidemiologic Studies Depression Scale. The students were divided into two groups; (1) those who received scholarships and (2) those who didn't since we thought the division represented practical patterns of their financial status. The associations of socio-demographic characteristics with depressive symptoms were examined. Of the 726 students, 480 (66.1%) responded and 207 (43.1%) had depressive symptoms. The logistic regression analysis indicated that quality of sleep, amount of exercise, and housing conditions--but not financial status--were statistically associated with the risk of developing depressive symptoms. Although the inversion of the cause and effect is yet to be ascertained, the students who are unsatisfied with their housing conditions, quality of sleep and less exercise need more attention.

  13. Learning in an Online Distance Education Course: Experiences of Three International Students

    2010-03-01

    Full Text Available This case study explores the learning experiences of three international students who were enrolled in an online master’s program offered by a large university in Canada. The aim of the study was to understand the international students’ experiences with, and perspectives on, the online learning environment. Findings indicate that previous education and especially language proficiency strongly impacted the learning of these students in this environment. Non-native English speakers required considerably more time to process readings and postings and to make postings themselves. Their lack of familiarity with the details of North American culture and colloquial language made it difficult to follow much of the course discussion. They also tended to avoid socializing in the course, which left them at the periphery of course activities. Based on these findings, the authors make the following recommendations for designers and instructors of online courses: 1 Raise the English language proficiency requirement for graduate admissions into online programs because the text-based communication in a CMC space requires interpreting messages without non-verbal cues; 2 Ensure that online distance education course designers are aware of the needs and expectations of international students; and 3 Combine the design principles from both traditional and constructivism theories.

  14. Critical Ethnographic Analysis of "Doing Good" on Short-Term International Immersion Experiences.

    Reciprocal partnerships are growing alongside the rise of international learning and "doing" experiences for students and clinicians. This paper questions how global citizenship, the acquisition of awareness and skills to sensitively navigate through a rapidly globalized social world, is cultivated amidst international partnerships focused on short-term immersion opportunities. Using an ethnographic methodology to examine the experiences of occupational therapy students abroad, this paper addresses the potential for competing agendas when the motivation to participate within these partnerships is driven in part by a desire to "do good." The empirical lens was directed towards the students' verbal, written and enacted narratives rather than the sociocultural realm of the sending institution, the host organization or the occupational realities of the local communities, therefore is limited in discursive scope. Nevertheless, the need is great for further critical appraisal of objectives and expectations by all parties to foster a partnership culture of reciprocity and equality and to diminish the neocolonial legacy of Western expertise dissemination. By examining how the stated and implied desire to do good exists alongside the risk to do harm to individuals and international networks, the conclusions can be extended locally to highlight the challenges to "partnering up" between clinicians and patients. © 2015 John Wiley & Sons, Ltd.

    Full Text Available Introduction: the method and way of learning and teaching are effective in acquiring clinical skills, and identifying the shortcomings of learning and teaching will lead to better planning. The purpose of this study was to explain the experiences of the learning clinical procedures of the internal medicine residents in gastroenterology department. Methods: qualitative study using content thematic analysis was done. Six fourth-year residents were selected and interviewed considering purposive sampling. The data of the interviews were transcribed and analyzed after rereading. Results: the collected data are divided into three categories: learning and experience with the following four categories (learning time and experiencing, leaning and experiencing times, learning and experiencing opportunities, training and the lack of the training of some procedures. These categories are explained by using some quotes derived from the data. Conclusion: the results of this study suggest that the administrative management of internal residency is poor and should get seriously in implementation and application of intended instructions existing in the prepared program of Medical Education and Specialized Council of internal residency period. The attending physicians and residents must be aware of the content of education program at the beginning of the residency periods and the trainers must try to supervise the residents’ education.

    Materials degradation due to the aging phenomena is one of the key issues for the life assessment and extension of the light water reactors (LWRs). This presentation introduces JAERI`s activities in the field of LWR material researches which utilize the research and testing reactors for irradiation experiments. The activities are including the material studies for the core internals, pressure vessel and fuel cladding. These materials are exposed to the neutron/gamma radiation and high temperature water environments so that it is worth reviewing their degradation phenomena as the continuum. Three topics are presented; For the core internal materials, the irradiation assisted stress corrosion cracking (IASCC) of austenitic stainless steels is the present major concern. At JAERI the effects of alloying elements on IASCC have been investigated through the post-irradiation stress corrosion cracking tests in high-temperature water. The radiation embrittlement of pressure vessel steels is still a significant issue for LWR safety, and at JAERI some factors affecting the embrittlement behavior such as a dose rate have been investigated. Waterside corrosion of Zircaloy fuel cladding is one of the limiting factors in fuel rod performance and an in-situ measurement of the corrosion rate in high-temperature water was performed in JMTR. To improve the reliability of experiments and to extent the applicability of experimental techniques, a mutual utilization of the technical achievements in those irradiation experiments is desired.

    The Energy Foundation's China Sustainable Energy Program (CSEP) has undertaken a major project investigating fiscal and tax policy options for stimulating energy efficiency and renewable energy development in China. This report, which is part of the sectoral sub-project studies on energy efficiency in industry, surveys international experience with tax and fiscal policies directed toward increasing investments in energy efficiency in the industrial sector. The report begins with an overview of tax and fiscal policies, including descriptions and evaluations of programs that use energy or energy-related carbon dioxide (CO2) taxes, pollution levies, public benefit charges, grants or subsidies, subsidized audits, loans, tax relief for specific technologies, and tax relief as part of an energy or greenhouse gas (GHG) emission tax or agreement scheme. Following the discussion of these individual policies, the report reviews experience with integrated programs found in two countries as well as with GHG emissions trading programs. The report concludes with a discussion of the best practices related to international experience with tax and fiscal policies to encourage investment in energy efficiency in industry.

    Full Text Available International university students are a growing section of the workforce and are thought to be at greater risk of injury. Qualitative studies have highlighted vulnerabilities, but there is a shortage of quantitative research exploring the injury experience and associated risk factors of this emerging issue. In this study, a total of 466 university student workers across a range of study programs in a single Australian university completed an online survey, with questions relating to their background, working experience, training and injury experience. Risk factors for injury were explored in a multivariate statistical model. More than half had not received any safety training before they started work, and 10% reported having had a work injury. About half of these injuries occurred after training. Statistically significant risk factors for injury included working more than 20 h per week (adjusted odds ratio 2.20 (95% CI 1.03–4.71 and lack of confidence in discussing safety issues (AOR 2.17; 95% CI 1.13–4.16. The findings suggest the need for a more engaging and effective approach to safety education and a limit on working hours. This situation is a moral challenge for universities, in that they are effectively sponsoring young workers in the community. It is recommended that longitudinal studies of international student workers be conducted.

    The International IPY Education, Outreach, and Communication Committee developed quarterly International Polar Days in response to pressure from educators and media wishing to remain involved in IPY, throughout IPY. Between September 2007 and March 2009 these events focus on aspects of polar research that are both specific enough to allow depth of understanding, but also broad enough to highlight the interconnectivity of polar science. Each day has experimented with different communication tools including multilingual activity and summary sheets, live radio and web events, press releases, local lectures and engagement at conferences. A virtual balloon launch helps us to assess our reach and develop plans for the next event. The talk will present an evaluation from the balloon launch as well as lessons learnt from activities that had varying degrees of success.

    The Stratospheric Aerosol and Gas Experiment III on International Space Station (SAGE3/ISS) is anticipated to be delivered to Cape Canaveral in the spring of 2015. This is the fourth generation, fifth instrument, of visible/near-IR solar occultation instruments operated by the National Aeronautics and Space Agency (NASA) to investigate the Earth's upper atmosphere. The instrument is a moderate resolution spectrometer covering wavelengths from 290 nm to 1550 nm. The nominal science products include vertical profiles of trace gases, such as ozone, nitrogen dioxide and water vapor, along with multi-wavelength aerosol extinction. The SAGE3/ISS validation program will be based upon internal consistency of the measurements, detailed analysis of the retrieval algorithm, and comparisons with independent correlative measurements. The Instrument Payload (IP), mission architecture, and major challenges are also discussed.

    Recent studies show an alarming increase in levels of overweight and obesity among children and adolescents. The main objectives of this research were the following: (i) to carry out an anthropometric evaluation of the nutritional status and body composition of school children in the city and province of Granada; (ii) to compare the nutritional status of this population sample with national and international reference standards. The results obtained in this study showed that the general prevalence of overweight in both sexes was 22.03% and that 9.12% of the children were obese. Statistically significant differences were found between the variable, weight for age and sex (p < 0.05) and the variable, height for age and sex (p < 0.05). Regarding the body mass index, no statistically significant differences were found for the variable, sex (p = 0.182). This contrasted with the variable, age, which did show statistically significant differences (p < 0.05). As a conclusion, the results of our study highlighted the fact that these anthropometric values were much higher than national and international reference standards.

    Full Text Available The U.S. is fast becoming more culturally diverse, creating a greater need for entry-level occupational therapists to be culturally competent. In order to increase students’ cultural competence, there is a growing support for international service learning (ISL. The purpose of this qualitative research study was to explore the perspectives of occupational therapy practitioners who engaged in ISL as occupational therapy students. Interviews were conducted with nine practicing occupational therapists, all of whom graduated from the same occupational therapy program in the U.S. and participated in an ISL experience in Guatemala. Phenomenological methods were used to analyze the transcribed interviews for codes, categories, and themes. The three themes that emerged were: Participants reported encountering many new experiences that led to experiencing a variety of emotions, their experiences in the Guatemalan culture further contributed to a deeper level of understanding about culture, and all of the participants reported that their ISL experiences allowed them to practice occupational therapy skills and interventions with limited resources, which facilitated creativity and resourcefulness. The findings of this study support that completing ISL as students contributes to occupational therapists’ personal and professional lives and offers a glimpse of potential long-term effects of completing an ISL experience.

    One rice ( Oryza sativa ) gene, sucrose phosphate synthase (SPS), has been proven to be a suitable endogenous reference gene for genetically modified (GM) rice detection in a previous study. Herein are the reported results of an international collaborative ring trial for validation of the SPS gene as an endogenous reference gene and its optimized qualitative and quantitative polymerase chain reaction (PCR) systems. A total of 12 genetically modified organism (GMO) detection laboratories from seven countries participated in the ring trial and returned their results. The validated results confirmed the species specificity of the method through testing 10 plant genomic DNAs, low heterogeneity, and a stable single-copy number of the rice SPS gene among 7 indica varieties and 5 japonica varieties. The SPS qualitative PCR assay was validated with a limit of detection (LOD) of 0.1%, which corresponded to about 230 copies of haploid rice genomic DNA, while the limit of quantification (LOQ) for the quantitative PCR system was about 23 copies of haploid rice genomic DNA, with acceptable PCR efficiency and linearity. Furthermore, the bias between the test and true values of eight blind samples ranged from 5.22 to 26.53%. Thus, we believe that the SPS gene is suitable for use as an endogenous reference gene for the identification and quantification of GM rice and its derivates.

    To identify and quantify the main concepts included in published studies focusing on individuals with schizophrenia using the International Classification of Functioning, Disability and Health (ICF). Searches (limited to those published from 2008 to 2012) were performed in MEDLINE, PsycINFO and CINAHL. Included studies described participants with schizophrenia, were original articles and included only subjects who were at least 18 years of age at study entry. All concepts underlying the measures and the text of the articles were extracted, and they were linked to ICF categories using standardized rules. From the 3584 abstracts retrieved, 348 were randomly selected, and of these, 206 studies met the inclusion criteria. A total of 17,141 concepts were extracted, 84.8% of which could be linked to 491 ICF categories: 222 (45.21%) of the categories referred to Body Functions, 29 (5.91%) to Body Structures, 186 (37.88%) to Activities and Participation and 54 (11%) to Environmental Factors. Seventy second-level categories were reported in at least 5% of all studies: 30 of these categories referred to Body Functions, 2 to Body Structures, 34 to Activities and Participation and 4 to Environmental Factors. The study has allowed us to identify and quantify the main concepts included in studies focusing on people with schizophrenia using the ICF. The majority of the concepts refer to Body Functions and Activities and Participation, rather than to Body Structures and Environmental Factors.

    Adolescent girls today suffer from internalizing problems such as somatic symptoms and mental health problems at higher rates compared to those of previous decades, and effective interventions are warranted. The aim of this study was to explore the experiences of participating in an 8-month dance intervention. This qualitative study was embedded in a randomized controlled trial of a dance intervention for adolescent girls with internalizing problems. A total of 112 girls aged 13–18 were included in the study. The dance intervention group comprised 59 girls, 24 of whom were strategically chosen to be interviewed. Data were analyzed using qualitative content analysis with an inductive approach. The experiences of the dance intervention resulted in five generic categories: (1) An Oasis from Stress, which represents the fundamental basis of the intervention; (2) Supportive Togetherness, the setting; (3) Enjoyment and Empowerment, the immediate effect; (4) Finding Acceptance and Trust in Own Ability, the outcome; and (5) Dance as Emotional Expression, the use of the intervention. One main category emerged, Finding Embodied Self-Trust That Opens New Doors, which emphasizes the increased trust in the self and the ability to approach life with a sense of freedom and openness. The central understanding of the adolescent girls’ experiences was that the dance intervention enriched and gave access to personal resources. With the non-judgmental atmosphere and supportive togetherness as a safe platform, the enjoyment and empowerment in dancing gave rise to acceptance, trust in ability, and emotional expression. Taken together, this increased self-trust and they discovered a new ability to “claim space.” Findings from this study may provide practical information on designing future interventions for adolescent girls with internalizing problems.

  10. New design and facilities for the International Database for Absolute Gravity Measurements (AGrav): A support for the Establishment of a new Global Absolute Gravity Reference System

    2017-04-01

    After about 10 years of successful joint operation by BGI and BKG, the International Database for Absolute Gravity Measurements "AGrav" (see references hereafter) was under a major revision. The outdated web interface was replaced by a responsive, high level web application framework based on Python and built on top of Pyramid. Functionality was added, like interactive time series plots or a report generator and the interactive map-based station overview was updated completely, comprising now clustering and the classification of stations. Furthermore, the database backend was migrated to PostgreSQL for better support of the application framework and long-term availability. As comparisons of absolute gravimeters (AG) become essential to realize a precise and uniform gravity standard, the database was extended to document the results on international and regional level, including those performed at monitoring stations equipped with SGs. By this it will be possible to link different AGs and to trace their equivalence back to the key comparisons under the auspices of International Committee for Weights and Measures (CIPM) as the best metrological realization of the absolute gravity standard. In this way the new AGrav database accommodates the demands of the new Global Absolute Gravity Reference System as recommended by the IAG Resolution No. 2 adopted in Prague 2015. The new database will be presented with focus on the new user interface and new functionality, calling all institutions involved in absolute gravimetry to participate and contribute with their information to built up a most complete picture of high precision absolute gravimetry and improve its visibility. A Digital Object Identifier (DOI) will be provided by BGI to contributors to give a better traceability and facilitate the referencing of their gravity surveys.

    To obtain local reference values for blood lipids and blood pressure (BP), and to determine the prevalence of metabolic syndrome (MS) in children and adolescents from Mérida, Venezuela, and to compare results using local and international cut-off values. The study enrolled 916 participants of both sexes aged 9-18 years of age from educational institutions. Demographic, anthropometric, and BP data were collected. Fasting blood glucose and lipid profile were measured. Percentile distribution of lipid and BP values was done by age group and sex. Prevalence of MS was estimated based on the NCEP-ATPIII classification (as modified by Cook et al.) and the classification of the International Diabetes Federation, using percentiles of Mérida and the USA as cut-off points. Agreement between both classifications was estimated using the kappa test (κ). Prevalence of MS was 2.2% by Cook-Merida percentiles, as compared to 1.8% by Cook-USA percentiles, a moderate agreement (κ=0.54). Agreement between Cook et al. and IDF using Merida percentiles was weak (κ=0.28). There was a higher frequency of abdominal obesity, hypertriglyceridemia and hypertension, and a lower frequency of low HDL-C using Mérida percentiles. The risk (odds ratio) of having MS is greater if abdominal obesity exists (OR: 98.63, CI: 22.45-433.35, p=0.0001). MS was significantly more common in obese subjects (18.3%, p=0.0001). Prevalence of MS in this sample of children and adolescents was 2.2%. Lipid and BP values were lower in Venezuelan as compared to US, European, and Asian children and adolescents, and similar to those in Latin-American references. Own reference values are required for accurate diagnosis of MS, as well as a worldwide consensus on its diagnostic criteria. Copyright © 2014 SEEN. Published by Elsevier Espana. All rights reserved.

    In 1999, a community college in Florida initiated a study abroad program that included a transcultural nursing Web-based course and a 2-week clinical component in Ecuador. The investigator collected data from 36 participants using Zorn's International Education Survey to measure 4 dimensions of impact of the international experience. Results revealed that impact on the professional role dimension was most significant, followed by the international perspective dimension, the personal development dimension, and the intellectual development dimension. Conclusions were that nursing international experiences do influence nurses' future professional and personal development.

    The Alpha Magnetic Spectrometer experiment is realized in two phases. A precursor flight (STS-91) with a reduced experimental configuration (AMS01) has successfully flown on space shuttle Discovery in June 1998. The final version (AMS02) will be installed on the International Space Station (ISS) as an independent module in early 2006 for an operational period of three years. The main scientific objectives of AMS02 include the searches for the antimatter and dark matter in cosmic rays. In this work we will discuss the experimental details as well as the improved physics capabilities of AMS02 on ISS.

    Some second language (L2) learners return from study abroad experiences with seemingly no change in their L2 ability. In this study we investigate whether a certain level of internal cognitive resources is necessary in order for individuals to take full advantage of the study abroad experience. Specifically, we examined the role of working memory resources in lexical comprehension and production for learners who had or had not studied abroad. Participants included native English learners of Spanish. Participants completed a translation recognition task and a picture-naming task. The results suggest that individuals who lack a certain threshold of working memory resources are unable to benefit from the study abroad context in terms of being able to produce accurately in the L2.

    More efficient methodology for assessing the impact of combined exposures to multiple chemicals has been considered in a project of the World Health Organization (WHO) International Programme on Chemical Safety (IPCS). Recommendations regarding terminology and the status of development of the framework, its content, review and application are described. Evolving experience in its application is illustrated by example (polybrominated diphenyls) with special emphasis on the critical content of problem formulation, the role of predictive tools in grouping of chemicals for consideration and the importance of explicit delineation of relative uncertainty and sensitivity for tiered assessment. Priorities in increasing the efficiency of risk assessment not only for combined exposures, but more generally based on experience acquired in developing the framework and its application in case studies are identified and recommendations included

    1999-01-01

    This paper provides an overview of the microgravity fluid physics and transport phenomena experiments planned for the International Spare Station. NASA's Office of Life and Microgravity Science and Applications has established a world-class research program in fluid physics and transport phenomena. This program combines the vast expertise of the world research community with NASA's unique microgravity facilities with the objectives of gaining new insight into fluid phenomena by removing the confounding effect of gravity. Due to its criticality to many terrestrial and space-based processes and phenomena, fluid physics and transport phenomena play a central role in the NASA's Microgravity Program. Through widely publicized research announcement and well established peer-reviews, the program has been able to attract a number of world-class researchers and acquired a critical mass of investigations that is now adding rapidly to this field. Currently there arc a total of 106 ground-based and 20 candidate flight principal investigators conducting research in four major thrust areas in the program: complex flows, multiphase flow and phase change, interfacial phenomena, and dynamics and instabilities. The International Space Station (ISS) to be launched in 1998, provides the microgravity research community with a unprecedented opportunity to conduct long-duration microgravity experiments which can be controlled and operated from the Principal Investigators' own laboratory. Frequent planned shuttle flights to the Station will provide opportunities to conduct many more experiments than were previously possible. NASA Lewis Research Center is in the process of designing a Fluids and Combustion Facility (FCF) to be located in the Laboratory Module of the ISS that will not only accommodate multiple users but, allow a broad range of fluid physics and transport phenomena experiments to be conducted in a cost effective manner.

    2017-01-01

    The International Reactor Physics Evaluation (IRPhE) Project was initiated as a pilot in 1999 by the Nuclear Energy Agency (NEA) Nuclear Science Committee (NSC). The project was endorsed as an official activity of the NSC in June 2003. While the NEA co-ordinates and administers the IRPhE Project at the international level, each participating country is responsible for the administration, technical direction and priorities of the project within their respective countries. The information and data included in this handbook are available to NEA member countries, to all contributing countries and to others on a case-by-case basis. The IRPhE Project is patterned after the International Criticality Safety Benchmark Evaluation Project (ICSBEP). It closely co-ordinates with the ICSBEP to avoid duplication of efforts and publication of conflicting information. Some benchmark data are applicable to both nuclear criticality safety and reactor physics technology. Some have already been evaluated and published by the ICSBEP, but have been extended to include other types of measurements in addition to the critical configuration. Through this effort, the IRPhE Project will be able to 1) consolidate and preserve the existing worldwide information base; 2) retrieve lost data; 3) identify areas where more data are needed; 4) draw upon the resources of the international reactor physics community to help fill knowledge gaps; 5) identify discrepancies between calculations and experiments due to deficiencies in reported experimental data, cross-section data, cross-section processing codes and neutronics codes; 6) eliminate a large amount of redundant research and processing of reactor physics experiment data, and 7) improve future experimental planning, execution and reporting. This handbook contains reactor physics benchmark specifications that have been derived from experiments performed at nuclear facilities around the world. The benchmark specifications are intended for use by

    We report the design, construction, and performances of a microwave (MW) heating device for laboratory experiments with non-contact, homogeneous internal heating. The device generates MW radiation at 2.47 GHz from a commercial magnetron supplied by a pulsed current inverter using proprietary, feedback based command and control hardware and software. Specially designed MW launchers direct the MW radiation into the sample through a MW homogenizer, devised to even the MW power distribution into the sample's volume. An adjustable MW circuit adapts the MW generator to the load (i.e., the sample) placed in the experiment chamber. Dedicated heatsinks maintain the MW circuits at constant temperature throughout the experiment. Openings for laser scanning for image acquisition with a CCD camera and for the cooling circuits are protected by special MW filters. The performances of the device are analyzed in terms of heating uniformity, long term output power stability, and load matching. The device is used for small scale experiments simulating Earth's mantle convection. The 30 × 30 × 5 cm(3) convection tank is filled with a water‑based viscous fluid. A uniform and constant temperature is maintained at the upper boundary by an aluminum heat exchanger and adiabatic conditions apply at the tank base. We characterize the geometry of the convective regime as well as its bulk thermal evolution by measuring the velocity field by Particle Image Velocimetry and the temperature field by using Thermochromic Liquid Crystals.

    Against the background of a planned re-orientation of the Austrian maternity and child programme, which might include an electronic instead of paper-based realisation, this article aims to give an overview of international pilot projects of electronic parent-child preventive care initiatives (ePCPI) as well as their aims, potentials and constraints. A literature search in databases and hand search for international (pilot) projects was undertaken. 9 of the 30 identified ePCPI can be treated as electronic parent and/or child health records, which have been realised within a comprehensive electronic health record, as an electronic version of a paper-based document or as a centre-based IT solution. Only a few ePCPI use the additional potential of health services planning and evaluation besides core components (e. g., administration of care) and facilitate systemic learning based on feedback and evaluation -cycles. Based on experiences from international ePCPIs some core components of successful planning and implementation, like the definition of aims and their monitoring, the constitution of teams responsible for planning and conception and the early involvement of end-users and stakeholders, should be considered to minimise avoidable mistakes. Consequent technology assessments, including those of IT-based interventions, are required to allow a reflected approach. © Georg Thieme Verlag KG Stuttgart · New York.

    The International Criticality Safety Benchmark Evaluation Project (ICSBEP) was initiated in 1992 by the United States Department of Energy. The ICSBEP became an official activity of the Organization for Economic Cooperation and Development (OECD) -- Nuclear Energy Agency (NEA) in 1995. Representatives from the United States, United Kingdom, France, Japan, the Russian Federation, Hungary, Republic of Korea, Slovenia, Serbia and Montenegro (formerly Yugoslavia), Kazakhstan, Spain, Israel, Brazil, Poland, and the Czech Republic are now participating. South Africa, India, China, and Germany are considering participation. The purpose of the ICSBEP is to identify, evaluate, verify, and formally document a comprehensive and internationally peer-reviewed set of criticality safety benchmark data. The work of the ICSBEP is published as an OECD handbook entitled 'International Handbook of Evaluated Criticality Safety Benchmark Experiments'. The 2004 Edition of the Handbook contains benchmark specifications for 3331 critical or subcritical configurations that are intended for use in validation efforts and for testing basic nuclear data. The Handbook is being used extensively for validation of criticality safety methodologies and nuclear data testing and is expected to be a valuable resource for code and data validation and improvement efforts for decades to come.

    Internal medicine residents are frequently called upon to provide palliative care to hospitalized patients, but report feeling unprepared to do so effectively. Curricular development to enhance residents' palliative care skills and competencies requires an understanding of current beliefs, attitudes and learning priorities. We conducted a qualitative study consisting of semi-structured interviews with ten internal medicine residents to explore their understanding of and experiences with palliative care. All of the residents interviewed had a sound theoretical understanding of palliative care, but faced many challenges in being able to provide care in practice. The challenges described by residents were system-related, patient-related and provider-related. They identified several priority areas for further learning, and discussed ways in which their current education in palliative care could be enhanced. Our findings provide important insights to guide curricular development for internal medicine trainees. The top five learning priorities in palliative care that residents identified in our study were: 1) knowing how and when to initiate a palliative approach, 2) improving communication skills, 3) improving symptom management skills, 4) identifying available resources, and 5) understanding the importance of palliative care. Residents felt that their education in palliative care could be improved by having a mandatory rotation in palliative care, more frequent didactic teaching sessions, more case-based teaching from palliative care providers, opportunities to be directly observed, and increased support from palliative care providers after-hours.

    Mice represent one of the most important animal models for biomedical research. In the past decade mice have been used as surrogates to understand physiological adaption and its under-lying mechanisms to orbital spaceflight. A breakthrough in this field has been achieved with the launch of MDS experiment inside Shuttle Discovery (mission STS-128) on August 28, 2009 at 23:58 EST, and its re-entry to earth by Shuttle Atlantis (mission STS-129) on November 27 2009 at 9:47 EST, marking this as the first long duration animal experiment on the Interna-tional Space Station (ISS). This presentation will provide the life history and milestones starting from the project brainstorm to the post-ground activities of the recent MDS payload mission. The Italian Space Agency (ASI) initiated and coordinated this multi-disciplinary project by focusing on five areas: the development of a multi-purpose automated payload by industry; bio-compatibility tests of subsystems throughout various critical phases of the payload development by researchers, development of a ground segment to interface with NASA Payload Operations Center and three different geographically distributed Italian Operations Centers; establishment of an international tissue sharing program; specialized bio-specimen intercontinental shipment. With close collaboration with NASA, activities such as pre-flight payload acceptance, animal preparation, in-flight crew intervention and re-entry animal recovery were smoothly and swiftly accomplished.

    Since the mid-1990s, a large number of foreign women have migrated from developing countries to South Korea by means of international marriages. These nulliparous foreign women may experience more difficulties in pregnancy and childbirth than native Koreans. This study aimed to describe the meaning of the first childbirth experiences of international marriage migrant women marrying Korean men in South Korea. This is a descriptive phenomenological study that included 10 participants using the purposive and snowball sampling in one multicultural support center in Seoul, South Korea. Colaizzi's data analysis method was used to inductively determine themes and formulate meanings. The meanings of first childbirth were categorized into four themes-'coming to a crisis,' 'depending on others,' 'searching for solutions,' and 'strengthening family unity.' Inadequate antenatal care is associated with obstacles such as language barriers, social isolation, lack of knowledge, different midwifery practice and dependent lifestyle. Meanwhile, their children were a source of energy for the women to fulfill their emotional needs and improve family relationships. Childbirth is a life-changing event for these women, in which they face challenges as well as opportunities to develop new coping skills and a new role identity in their family. It is important for healthcare providers and policy makers to identify obstacles and unmet needs to improve maternity care in light of the distinctive challenges of immigrant living in multicultural families.

    To analyse the literature regarding the context and experiences of internationally qualified registered nurses, particularly Filipino and Indian nurses, who have transitioned to New Zealand. Internationally qualified nurses are a significant proportion of the nursing workforce in many developed countries including New Zealand. This is increasingly important as populations age, escalating demand for nurses. Understanding the internationally qualified nurse experience is required as this could influence migration in a competitive labour market. Examination of peer-reviewed research, policy and discussion documents, and technical reports. A systematic literature search sought articles published between 2001 and 2014 using Google Scholar, CINAHL, and Medline. Articles were critically appraised for relevance, transferability, and methodological rigour. Fifty-one articles met inclusion criteria and demonstrate internationally qualified nurses face significant challenges transitioning into New Zealand. The internationally qualified nurse experience of transitioning into a new country is little researched and requires further investigation.

    The current study explores the potential mediating role of internalized racism in the relationship between racist experiences and anxiety symptomology in a Black American sample. One hundred and 73 Black American participants, between 18 and 62 years of age, completed a questionnaire packet containing measures of anxious arousal and stress symptoms, internalized racism, and experiences of racist events. Results indicated that internalized racism mediated the relationship between past-year frequency of racist events and anxious arousal as well as past-year frequency of racist events and stress symptoms. Internalized racism may be 1 mechanism that underlies the relationship between racism and anxious symptomology for Black Americans. These preliminary findings suggest that internalized racism may be an avenue through which clinicians can target the anxiety elicited by racist experiences. The clinical implications of these findings and future research directions are discussed. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

    Detailed discussions were held with members of the Gallium Experiment (GALLEX) international solar neutrino research collaboration concerning negotiations to provide $1.4 million in services to enrich (50)Cr for a (51)Cr neutrino source. The source will be used to calibrate the 20-ton gallium solar neutrino detector currently in place in the Gran Sasso Laboratory in Italy. Funding approval for the enrichment services is expected from the European Common Market by October 19, 1990. The discussions focused on the technical aspects of the enrichment, the health and safety requirements for handling the process gas, cost projections, schedule, the Work-for-Others contract, and the method of payment. Discussions were also held with members of the Nuclear Physics Dept. at the University of Milan concerning the availability of isotopes enriched by the Calutron at the Oak Ridge National Laboratory. Very high purity material is needed to grow crystals for use in double beta decay detectors. Finally, working sessions were held to draft a coauthored paper on the results of using the gas centrifuge to remove trace quantities of (85)Kr from natural xenon.
