    The Imaging IR Limb Sounder (IRLS) is one of the two instruments planned on board of the candidate Earth Explorer Core Mission PREMIER. PREMIER stands for PRocess Exploration through Measurements of Infrared and Millimetrewave Emitted Radiation and is presently under feasibility study by ESA. Emerging from recent enhanced detector and processing technologies IRLS shall, next to a millimetre-wave limb sounder, explore the benefits of three-dimensional limb sounding with embedded cloud imaging capability. Such 3d imaging technology is expected to open a new era of limb sounding that will allow detailed studies of the link between atmospheric composition and climate, since it will map simultaneously fields of temperature and many trace gases in the mid/upper troposphere and stratosphere across a large vertical and horizontal field of view and with relatively high vertical and horizontal resolution. PREMIER shall fly in tandem formation looking backwards to METOP's swath and thereby explore the benefit of 3-dimensional information for meteorological/environmental analyses and climate forcing investigations. As currently planned and if implemented, IRLS will cover a total horizontal field of about 360 km and observe the limb at altitudes between 4 and 52 km. The vertical spatial sampling distance (SSD) will be well below 1 km. It will be run in two different exclusive modes to address scientific questions about atmospheric dynamics and chemistry at spectral samplings of ~1.2 cm-1 and ~0.2 cm-1, respectively. In such configuration IRLS will be composed of an imaging array with about 1800 macro pixels or sub-samples, thereby allowing cloud imaging and rejection at sufficient spatial resolution. We will present an overview of the instrument requirements as derived from the scientific requirements, the present status of the mission, and we will give an overview of the currently identified technology needs and instrument predevelopments.

    2008-01-01

    ITT Space Systems Division s new Precision Cleaning facility provides critical cleaning and packaging of aerospace flight hardware and optical payloads to meet customer performance requirements. The Precision Cleaning Path to Premier Project was a 2007 capital project and is a key element in the approved Premier Resource Management - Integrated Supply Chain Footprint Optimization Project. Formerly precision cleaning was located offsite in a leased building. A new facility equipped with modern precision cleaning equipment including advanced process analytical technology and improved capabilities was designed and built after outsourcing solutions were investigated and found lacking in ability to meet quality specifications and schedule needs. SSD cleans parts that can range in size from a single threaded fastener all the way up to large composite structures. Materials that can be processed include optics, composites, metals and various high performance coatings. We are required to provide verification to our customers that we have met their particulate and molecular cleanliness requirements and we have that analytical capability in this new facility. The new facility footprint is approximately half the size of the former leased operation and provides double the amount of throughput. Process improvements and new cleaning equipment are projected to increase 1st pass yield from 78% to 98% avoiding $300K+/yr in rework costs. Cost avoidance of $350K/yr will result from elimination of rent, IT services, transportation, and decreased utility costs. Savings due to reduced staff expected to net $4-500K/yr.

    DeVore, Susan D; Figlioli, Keith

    2010-04-01

    Implementing health information technology (IT) is a major strategic objective for providers. To pinpoint considerations that tie to success, the Premier health care alliance surveyed hospitals to develop an electronic health record best-practices library. Compiled from diverse health care organizations, the library outlines considerations to support "meaningful use" in the areas of computerized physician order entry, medication management, clinical documentation, reporting of measures, privacy, information exchange, management of populations' health, and personal health records. Best practices also uncovered strategies for securing executive leadership, culture change, communication, and support for clinicians. This paper summarizes lessons from the library, providing recommendations to speed up health IT implementation. PMID:20368596

  10. Measuring cardiac waste: the premier cardiac waste measures.

    PubMed

    Lowe, Timothy J; Partovian, Chohreh; Kroch, Eugene; Martin, John; Bankowitz, Richard

    2014-01-01

    The authors developed 8 measures of waste associated with cardiac procedures to assist hospitals in comparing their performance with peer facilities. Measure selection was based on review of the research literature, clinical guidelines, and consultation with key stakeholders. Development and validation used the data from 261 hospitals in a split-sample design. Measures were risk adjusted using Premier's CareScience methodologies or mean peer value based on Medicare Severity Diagnosis-Related Group assignment. High variability was found in resource utilization across facilities. Validation of the measures using item-to-total correlations (range = 0.27-0.78), Cronbach α (.88), and Spearman rank correlation (0.92) showed high reliability and discriminatory power. Because of the level of variability observed among hospitals, this study suggests that there is opportunity for facilities to design successful waste reduction programs targeting cardiac-device procedures.

    Little is known about the transition in behaviors from short-term weight loss to maintenance of weight loss. We wanted to determine how short-term and long-term weight loss and patterns of weight change were associated with intervention behavioral targets. This analysis includes overweight/obese participants in active treatment (n = 507) from the previously published PREMIER trial, an 18-month, multicomponent lifestyle intervention for blood pressure reduction, including 33 intervention sessions and recommendations to self-monitor food intake and physical activity daily. Associations between behaviors (attendance, recorded days/week of physical activity, food records/week) and weight loss of ≥5% at 6 and 18 months were examined using logistic regression. We characterized the sample using 5 weight change categories (weight gained, weight stable, weight loss then relapse, late weight loss, and weight loss then maintenance) and analyzed adherence to the behaviors for each category, comparing means with ANOVA. Participants lost an average of 5.3 ± 5.6 kg at 6 months and 4.0 ± 6.7 kg (4.96% of body weight) by 18 months. Higher levels of attendance, food record completion, and recorded days/week of physical activity were associated with increasing odds of achieving 5% weight loss. All weight change groups had declines in the behaviors over time; however, compared to the other four groups, the weight loss/maintenance group (n = 154) had statistically less significant decline in number of food records/week (48%), recorded days/week of physical activity (41.7%), and intervention sessions attended (12.8%) through 18 months. Behaviors associated with short-term weight loss continue to be associated with long-term weight loss, albeit at lower frequencies. Minimizing the decline in these behaviors may be important in achieving long-term weight loss. PMID:21455122

  14. Ar-40/Ar-39 laser-probe dating of diamond inclusions from the Premier kimberlite

    NASA Technical Reports Server (NTRS)

    Phillips, D.; Onstott, T. C.; Harris, J. W.

    1989-01-01

    The results of Ar-40/Ar-39 laser-probe analyses of individual eclogitic clinopyroxene inclusions from Premier diamonds are reported which yield a mean age of 1198 + or - 14 Myr. This age agrees well with Sm-Nd and Ar-40/Ar-39 analyses on similar Premier inclusions and is indistinguishable from the inferred time of emplacement of the host kimberlite, which implies that diamond formation was essentially synchronous with kimberlite generation. The extrapolated nonradiogenic Ar-40/Ar-36 ratio of 334 + or - 102 is similar to the present-day atmospheric composition. This value is inconsistent with Sr and Nd isotopic signatures from Premier eclogite inclusions, which suggest a depleted mantle source. Preentrapment equilibration of the inclusions with an Ar-36-rich fluid is the most probable explanation for the low nonradiogenic composition.

  15. NASA Names Premier X-Ray Observatory and Schedules Launch

    NASA Astrophysics Data System (ADS)

    1998-12-01

    NASA's Advanced X-ray Astrophysics Facility has been renamed the Chandra X-ray Observatory in honor of the late Indian-American Nobel laureate, Subrahmanyan Chandrasekhar. The telescope is scheduled to be launched no earlier than April 8, 1999 aboard the Space Shuttle Columbia mission STS-93, commanded by astronaut Eileen Collins. Chandrasekhar, known to the world as Chandra, which means "moon" or "luminous" in Sanskrit, was a popular entry in a recent NASA contest to name the spacecraft. The contest drew more than six thousand entries from fifty states and sixty-one countries. The co-winners were a tenth grade student in Laclede, Idaho, and a high school teacher in Camarillo, CA. The Chandra X-ray Observatory Center (CXC), operated by the Smithsonian Astrophysical Observatory, will control science and flight operations of the Chandra X-ray Observatory for NASA from Cambridge, Mass. "Chandra is a highly appropriate name," said Harvey Tananbaum, Director of the CXC. "Throughout his life Chandra worked tirelessly and with great precision to further our understanding of the universe. These same qualities characterize the many individuals who have devoted much of their careers to building this premier X-ray observatory." "Chandra probably thought longer and deeper about our universe than anyone since Einstein," said Martin Rees, Great Britain's Astronomer Royal. "Chandrasekhar made fundamental contributions to the theory of black holes and other phenomena that the Chandra X-ray Observatory will study. His life and work exemplify the excellence that we can hope to achieve with this great observatory," said NASA Administrator Dan Goldin. Widely regarded as one of the foremost astrophysicists of the 20th century, Chandrasekhar won the Nobel Prize in 1983 for his theoretical studies of physical processes important to the structure and evolution of stars. He and his wife immigrated from India to the U.S. in 1935. Chandrasekhar served on the faculty of the University of

  18. Transforming the Premier Perspective® Hospital Database into the Observational Medical Outcomes Partnership (OMOP) Common Data Model

    PubMed Central

    Makadia, Rupa; Ryan, Patrick B.

    2014-01-01

    Background: The Observational Medical Outcomes Partnership (OMOP) Common Data Model (CDM) has been implemented on various claims and electronic health record (EHR) databases, but has not been applied to a hospital transactional database. This study addresses the implementation of the OMOP CDM on the U.S. Premier Hospital database. Methods: We designed and implemented an extract, transform, load (ETL) process to convert the Premier hospital database into the OMOP CDM. Standard charge codes in Premier were mapped between the OMOP version 4.0 Vocabulary and standard charge descriptions. Visit logic was added to impute the visit dates. We tested the conversion by replicating a published study using the raw and transformed databases. The Premier hospital database was compared to a claims database, in regard to prevalence of disease. Findings: The data transformed into the CDM resulted in 1% of the data being discarded due to data errors in the raw data. A total of 91.4% of Premier standard charge codes were mapped successfully to a standard vocabulary. The results of the replication study resulted in a similar distribution of patient characteristics. The comparison to the claims data yields notable similarities and differences amongst conditions represented in both databases. Discussion: The transformation of the Premier database into the OMOP CDM version 4.0 adds value in conducting analyses due to successful mapping of the drugs and procedures. The addition of visit logic gives ordinality to drugs and procedures that wasn’t present prior to the transformation. Comparing conditions in Premier against a claims database can provide an understanding about Premier’s potential use in pharmacoepidemiology studies that are traditionally conducted via claims databases. Conclusion and Next Steps: The conversion of the Premier database into the OMOP CDM 4.0 was completed successfully. The next steps include refinement of vocabularies and mappings and continual maintenance of

  19. Development of a method to measure and compare hospital waste: the Premier hospital waste index.

    Lowe, Timothy J; Kroch, Eugene; Martin, John; Bankowitz, Richard

    2014-01-01

    The authors developed 15 measures and a comparative index to assist acute care facilities in identifying and monitoring clinical and administrative functions for health care waste reduction. Primary clinical and administrative data were collected from 261 acute care facilities contained within a database maintained by Premier Inc, spanning October 1, 2010, to September 30, 2011. The measures and 4 index models were tested using the Cronbach α coefficient and item-to-total and Spearman rank correlations. The final index model was validated using 52 facilities that had complete data. Analysis of the waste measures showed good internal reliability (α = .85) with some overlap. Index modeling found that data transformation using the standard deviation and adjusting for the proportional contribution of each measure normalized the distribution and produced a Spearman rank correlation of 0.95. The waste measures and index methodology provide a simple and reliable means to identify and reduce waste and compare and monitor facility performance. PMID:23687221

    Purpose Despite numerous studies which have been done regarding soccer injuries worldwide, there is lack of available data considering the epidemiology of injuries in the Iranian soccer premier league, although it is the most popular sport in the country. The main goal of this research was to determine the incidence of physical injuries in the studied population, considering other characteristics such as site, type and mechanism as well. Methods Twenty one adult male professional soccer players (age 24±3), members of a team (Tehran-Pas) participating in Iranian premier league, were followed during a 4-month period. The injury characteristics and exposure times were recorded by the team physician during all the matches and training sessions. Results The total exposure time was 2610 playing hours (2352 h of training versus 258 h of competition). Eighty six percent of the injuries were acute. Incidence of acute injuries was 16.5 (95% CI: 12-22) per 1000 hours of playing (11.5 per 1000 hrs of training and 62 per 1000 hrs of competition). The most common types of injuries were strains followed by contusions, each of which constituted 30% of acute injuries. More than 80% of injuries occurred in lower limbs, especially in thigh and groin regions. Nearly 60% of acute injuries occurred in dominant side of the body, and collision was the reason of about half of the acute injuries. Severity of more than 70% of the injuries was minor. On average each injury had led the player being off the field for about 10 days. Conclusion The incidence of injury in this research is in range of numbers obtained in important international tournaments but the rate of injuries during training sessions is higher than comparable studies.

    2014-12-01

    This study examined the evolution of physical and technical soccer performance across a 7-season period in the English Premier League. Match performance observations (n=14 700) were analysed for emergent trends. Total distance covered during a match was ~2% lower in 2006-07 compared to 2012-13. Across 7 seasons, high-intensity running distance and actions increased by ~30% (890±299 vs. 1 151±337 m, p<0.001; ES: 0.82) and ~50% (118±36 vs. 176±46, p<0.001; ES: 1.41), respectively. Sprint distance and number of sprints increased by ~35% (232±114 vs. 350±139 m, p<0.001; ES: 0.93) and ~85% (31±14 vs. 57±20, p<0.001; ES: 1.46), respectively. Mean sprint distance was shorter in 2012-13 compared to 2006-07 (5.9±0.8 vs. 6.9±1.3 m, p<0.001; ES: 0.91), with the proportion of explosive sprints increasing (34±11 vs. 47±9%, p<0.001; ES: 1.31). Players performed more passes (35±17 vs. 25±13, p<0.001; ES: 0.66) and successful passes (83±10% vs. 76±13%, p<0.001; ES: 0.60) in 2012-13 compared to 2006-07. Whereas the number of short and medium passes increased across time (p<0.001; ES>0.6), the number of long passes varied little (p<0.001; ES: 0.11). This data demonstrates evolution of physical and technical parameters in the English Premier League, and could be used to aid talent identification, training and conditioning preparation.

    The PREMIER (PRocess Exploration through Measurements of Infrared and millimetre-wave Emitted Radiation) mission is one of three candidates for ESA's 7th Earth Explorer Core Mission (due for launch in 2016) that have been approved for Phase A study. The mission proposes to make detailed measurements in the mid/upper troposphere and lower stratosphere in order to quantify processes controlling atmospheric global composition in this height range of particular importance to climate. PREMIER would consist of an infrared limb imaging spectrometer which would observe 3D fields of trace gases, alongside a millimetre-wave limb sounder which would enable observations in the presence of most cirrus clouds, and also provide complementary trace gases. In addition, co-located data from EPS-MetOp would be combined with that from PREMIER, to extend the scientific impact of PREMIER down into the lower troposphere, to explore links to surface emissions and pollution. In this presentation, simulations of its capabilities will be described together with some preliminary results from airborne precursors

  8. Motion analysis of U11 to U16 elite English Premier League Academy players.

    PubMed

    Goto, Heita; Morris, John G; Nevill, Mary E

    2015-01-01

    This study examined (1) the distances and speeds covered during match play for U11 to U16 English Premier League Academy players, (2) the differences in match performance between retained and released players and (3) the effect of calculating speed zones in different ways when analysing match performance. Eighty-one academy outfield players (10-16 years old), competing in 11-a-side matches, were analysed using a 1-Hz global positioning system with three speed zones (absolute, squad and individual). Pitch dimensions were 78.7 × 54.1 m (U11 and U12), 88.0 × 64.2 m (U13) and 100.8 × 68.2 m (U14-U16). Match durations were 20 min × 2 + 15 min × 2 or 25 min × 3 (U11), 25 min × 3 (U12 and U13) and 40 min × 2 (U14-U16). The matches were part of the regular series of inter-academy matches between Premier League Academies during a season. Completion of at least a half of the duration of a match in two separate matches (mean ± s = 3.1 ± 0.8 matches; range: 2-4 matches) was the criterion for inclusion in the study. Total match running distance increased with age from ~5700 (U11) to ~6700 m · h(-1) (U15) (P < 0.01). Using the absolute speed zones, it was possible to discern differences in high-intensity (>6.0 m · s(-1)) distance covered with age (U11: 29 m · h(-1), U16: 164 m · h(-1), P < 0.01). Using the squad speed zones, it was possible to discern differences between retained and released players in the U11/U12s (moderate-speed running) and in the U15/U16s (walking, jogging and low-speed running) (P < 0.01). Thus, total and high-intensity running distances increase with age, and walking, jogging, low-speed running and moderate-speed running distances are greater in retained than in released players and these differences are best identified through the use of absolute and squad speed zones, respectively.

  9. Evaluation of sports nutrition knowledge of New Zealand premier club rugby coaches.

    PubMed

    Zinn, Caryn; Schofield, Grant; Wall, Clare

    2006-04-01

    Little is known about if and how team coaches disseminate nutrition information to athletes. In a census survey, New Zealand premier rugby coaches (n = 168) completed a psychometrically validated questionnaire, received by either Internet or standard mail (response rate, 46%), identifying their nutrition advice dissemination practices to players, their level of nutrition knowledge, and the factors determining this level of knowledge. The majority of coaches provided advice to their players (83.8%). Coaches responded correctly to 55.6% of all knowledge questions. An independent t-test showed coaches who imparted nutrition advice obtained a significantly greater score, 56.8%, than those not imparting advice, 48.4% (P = 0.008). One-way ANOVA showed significant relationships between total knowledge score of all coaches and qualifications [F(1,166) = 5.28, P = 0.001], own knowledge rating [F(3,164) = 6.88, P = 0.001] and nutrition training [F(1,166) = 9.83, P = 0.002]. We conclude that these rugby coaches were inadequately prepared to impart nutrition advice to athletes and could benefit from further nutrition training. PMID:16779927

    2015-02-01

    This study aimed to investigate position-specific evolution of physical and technical performance parameters in the English Premier League (EPL). Match performance observations (n=14700) were collected using a multiple-camera computerized tracking system across seven seasons (2006-07 to 2012-13). Data were analyzed relative to five playing positions: central defenders (n=3792), full backs (n=3420), central midfielders (n=3200), wide midfielders (n=2136) and attackers (n=2152). High-intensity running distance increased in the final season versus the first season in all playing positions (p<.05, ES: 0.9-1.3) with full backs displaying the greatest increase (∼36% higher in 2012-13). Similar trends were observed for sprint distance with full backs demonstrating the most pronounced increase across the seven seasons (36-63%, p<.001, ES: 0.8-1.3). Central players (central defenders and midfielders) illustrated the most pronounced increases in total passes and pass success rate (p<.05, ES: 0.7-0.9) whilst wide players (full backs and wide midfielders) demonstrated only small-moderate increases in total passes and pass success rate (p<.05, ES: 0.6-0.8). The data demonstrates that evolving tactics in the EPL have impacted on the physical demands of wide players and the technical requirements of central players. These findings could be used for talent identification or position-specific physical and technical training. PMID:25461429

    Soccer, which has a large number of participants, has a high injury incidence that causes both financial and time burdens. Therefore, knowledge about the epidemiology of soccer injuries could allow sports-medicine professionals, such as physicians and physiotherapists, to direct their work in specific preventive programs. Thus, our aim was to conduct an epidemiological survey of injuries sustained by professional soccer players from the same team who participated in the Brazilian championship premier league in 2009. To this end, we evaluated retrospectively player medical records from the team, which included name, date of birth, position, date of injury, mechanism of injury, and type of injury. In the period of study, 95 injuries were recorded: 42 (44.2%) were recorded during matches, and 53 (55.8%) during the training period. Injuries occurred more frequently in midfielders and strikers. All injuries happened in the lower limb, most of the injuries were muscular, and most occurred as the result of collisions with other athletes. In summary, this study demonstrates that there is a need for greater safety awareness in the training environment. PMID:24379722

    2004-01-01

    Tunefulness in singing is well understood in the context of solo stage performance, singing in small groups and singing in choirs, with or without accompaniment, and it can be readily measured under laboratory conditions. When thousands of people are singing outside in support of their football team, however, the singing is impromptu; there is no conductor, no starting note, and generally no accompaniment. This paper describes the measurement of the tunefulness of the singing of fans of the twenty clubs in the 2001-2002 English Premier League. The technique adopted is unusual in that it makes direct reference to the formal definition of pitch as a subjective phenomenon. The results are presented in the form of a 2001-2002 English Premier League football fans singing league table. PMID:15260183

    Speeches given by General Secretary Jiang Zemin and Premier Li Peng to the forum on Family Planning (FP) Work in April 1991 are summarized. Jiang stated that the highest levels of communist party and governmental officials should be in charge of controlling population growth in China. There is great urgency to do so. The problems to be faced are a hugh population, scarce arable land, a poor economic foundation, and low per capita resources. Human resources are an asset for the socialist construction of China, but a rapid growth rate will retard economic and social development and affect the improvement in living standards and the quality of life. The strategy to place FP within state policy and place strict controls over population growth must be carried out resolutely. The future of socialism and the Chinese nation is at stake. Modernization cannot be accomplished with out controlling population growths. The 8th 5 year Plan and the 10 Year Program requirements will still contribute to 1.3 billion population by 2000 and 1.2 billion by 1995. There is historical responsibility, an urgency to strictly control population growth. Adherence to the 4 cardinal principles of socialism (the people's democratic dictatorship, the Communist Party leadership, and Marxist Leninist and Mao Zedong thought) must coexist with social development and family planning. All must be motivated. The provincial Party Secretary personally must oversee problems. The success or failure of FP should be used to evaluate the achievements of party committees and governments. The education on basic national conditions and the basic state policy on FP needs to be publicized through all organizations. There should be confidence in the masses. People must make FP their own cause voluntarily. Premier Li Peng stressed effective implementation and giving it high priority in order to achieve the 2nd step strategic goal of socialist modernization. Per capita output is low, and grain output will not increase

    Football is increasingly used to facilitate recovery in mental health services, often in partnership with football clubs. However, few clubs have made mental health part of their corporate social responsibility programmes until recently. We report the impact on participants of the 'Imagine Your Goals' programme, run by 16 Premier League football clubs in conjunction with England's Time to Change programme to reduce mental health-related stigma and discrimination. Mixed methods evaluation used pre/post measures of well-being, access to social capital, focus groups held early on and towards the end of the two-year programmes, and questionnaires for coaching staff. There were no significant changes to participants' mental well-being scores between baseline and follow-up, nor to the total number of social resources accessible through their networks. However, there was a statistically significant increase at follow-up in the mean score of the personal skills subscale of the Resource Generator-UK. Participants' individual skills were also higher at follow-up. Qualitative data showed programmes had largely met participants' expectations in terms of socializing, providing structure and improving fitness levels, exceeded expectations in relationships with coaching staff and additional activities, but did not always meet them in improving football skills. Participants varied in their knowledge of exit opportunities, depending on which club's programme they attended. A minority of clubs reported difficulties in recruitment and concerns about planning for the future of the projects. Football clubs and the charitable foundations they set up can successfully deliver programmes to people with mental health problems which improve access to personal skills social capital and have other potential benefits.

    The purpose of this paper is to provide, discuss, and interpret a comprehensive set of geochemical data (involving major elements as well as Ni, Ti, Sr, Y, Zr, Nb, Hf and the rare earth elements) for peridotitic garnets in diamonds from Premier and Finsch, with a view on the nature of the metasomatic processes operating up to the time of diamond crystallisation, and the location of these two diamondiferous kimberlites within and outside the region of low seismic velocity in the Kaapvaal lithosphere. Trace element data were acquired using an ion microprobe, and a new method for the analysis of Ni in garnet by ion microprobe is presented. Peridotitic garnets in diamonds from the Premier mine are characterised by a significantly higher proportion of the lherzolite paragenesis relative to diamonds from other South African mines, such as Finsch, Venetia and De Beers Pool. Based on Ni-in-garnet thermometry, inclusion encapsulation temperatures of 1055 °C to 1669 °C are calculated for peridotitic garnets from Premier, with an average temperature of 1215 °C. Calculated temperatures for garnets from Finsch range from 1036 °C to 1167 °C, and are generally lower than for Premier, with an average of 1098 °C. The garnets in the diamonds from Premier and Finsch reflect contrasting styles of metasomatism associated with diamond crystallisation, with a low temperature fluid-type metasomatism prevalent in the case of the Paleoarchean diamonds from Finsch, and a higher temperature melt-related metasomatism occurring in the case of the Paleoproterozoic diamonds from Premier. The metasomatic agent accompanying diamond crystallisation at Finsch is effective at introducing Sr, the light rare earth elements, and some Zr into the lithosphere, but is ineffective at transporting much Ca, Ti, Y and heavy rare earth elements. In the case of Premier the metasomatic agent is highly effective at element transport, introducing e.g. Ca, Fe, Ti, Zr, Y and the rare earth elements. The location

    Recruitment strategies employed by four clinical centers across the US and a coordinating center were examined to identify successful overall and minority-focused recruitment strategies for the PREMIER multicenter trial of lifestyle changes for blood pressure control. The goal was to recruit 800 adults (40% African Americans) with systolic blood pressure of 120-159 mm Hg and diastolic of 80-95 mm Hg, not taking antihypertensive medication. Clinical centers used combinations of mass distribution of brochures, mass media, email distribution lists, screening events, and a national website. Culturally appropriate strategies for African Americans were designed by a Minority Implementation (MI) committee. Diversity training was provided for study staff, and African Americans were included in the study design process. Main recruitment outcomes were number overall and number of African Americans recruited by each strategy. Of the 810 randomized PREMIER participants, 279 (34%) were African American with site-specific percentages of 56%, 46%, 27%, and 8%. Of African Americans recruited, 151 (54%) were from mass distribution of brochures (mailed letter, flyer included in Val-Pak coupons, or other), 66 (24%) from mass media (printed article, radio, TV story or ads, 52 (19%) from word of mouth, and 10 (3%) from email/website and screening events combined. Yields for Non-Hispanic Whites were 364 (69%) from brochures, 71 (13%) from mass media, 49 (9%) from word of mouth and 47 (9%) from email/website and screening events. Mass distribution of brochures was relatively more effective with Non-Hispanic Whites, while African Americans responded relatively better to other recruitment strategies. PMID:19879377

    Abstract Introduction: The primary aims of this study were to assess the learning curve effect of robot-assisted radical prostatectomy (RARP) in a large administrative database consisting of multiple U.S. hospitals and surgeons, and to compare the results of RARP with open radical prostatectomy (ORP) from the same settings. Materials and Methods: The patient population of study was from the Premier Perspective Database (Premier, Inc., Charlotte, NC) and consisted of 71,312 radical prostatectomies performed at more than 300 U.S. hospitals by up to 3739 surgeons by open or robotic techniques from 2004 to 2010. The key endpoints were surgery time, inpatient length of stay, and overall complications. We compared open versus robotic, results by year of procedures, results by case volume of specific surgeons, and results of open surgery in hospitals with and without a robotic system. Results: The mean surgery time was longer for RARP (4.4 hours, standard deviation [SD] 1.7) compared with ORP (3.4 hours, SD 1.5) in the same hospitals (p<0.0001). Inpatient stay was shorter for RARP (2.2 days, SD 1.9) compared with ORP (3.2 days, SD 2.7) in the same hospitals (p<0.0001). The overall complications were less for RARP (10.6%) compared with ORP (15.8%) in the same hospitals, as were transfusion rates. ORP results in hospitals without a robot were not better than ORP with a robot, and pretreatment co-morbidity profiles were similar in all cohorts. Trending of results by year of procedure showed no differences in the three cohorts, but trending of RARP results by surgeon experience showed improvements in surgery time, hospital stay, conversion rates, and complication rates. Conclusions: During the initial 7 years of RARP development, outcomes showed decreased hospital stay, complications, and transfusion rates. Learning curve trends for RARP were evident for these endpoints when grouped by surgeon experience, but not by year of surgery. PMID:24350787

    Background Bleeding remains a common occurrence in surgery. Data describing the burden of difficult-to-control bleeding and topical absorbable hemostat use are sparse. This study was conducted to estimate the clinical and economic impact that remains associated with uncontrolled surgical bleeding, even when hemostats are used during surgery. Methods This US retrospective analysis used the Premier Perspectives Database. Hospital discharges from 2012 were used to identify patients treated with hemostats during eight surgery types. Patients were included if they were ≥18 years, had an inpatient hospitalization with one of the eight surgeries, and received a hemostat on the day of surgery. Patients were stratified by procedure and presence or absence of major bleeding (uncontrolled) despite hemostat use. Outcomes were all-cause hospitalization costs, hemostat costs, length of stay, reoperation, and surgery-related complications (eg, mortality). Statistical significance was tested through chi-square or t-tests. Multivariate analyses were conducted for all-cause costs and length of stay using analysis of covariance. Results Among 25,048 procedures, major bleeding events occurred in 14,251 cases. Despite treatment with hemostats, major bleeding occurred in 32%–68% of cases. All-cause costs were significantly higher in patients with uncontrolled bleeding despite hemostat use versus controlled bleeding (US$24,203–$61,323 [uncontrolled], US$14,420–$45,593 [controlled]; P<0.001). Hemostat costs were significantly greater in the uncontrolled bleeding cohort for all surgery types except cystectomy and pancreatic surgery. Reoperation and mortality rates were significantly higher in the uncontrolled bleeding cohort in all surgical procedures except cystectomy and radical hysterectomy. Conclusion Uncontrolled intraoperative bleeding despite hemostat use is prevalent and associated with significantly higher hospital costs and worse clinical outcomes across several surgical

    2016-01-01

    Background: We sought to compare mortality rates and related diagnoses in hospitalized patients with multiple sclerosis (MS), those with diabetes mellitus (DM), and the general hospitalized population (GHP). Methods: Patients who died between 2007 and 2011 were identified in the US hospital–based Premier Healthcare Database. Demographic information was collected, mortality rates calculated, and principal diagnoses categorized. Results: Of 55,152 unique patients with MS identified, 1518 died. Mean age at death was 10 years younger for the MS group (63.4 years) than for the DM (73.3 years) and GHP (73.1 years) groups. Age-adjusted mortality rates, based on the 2000 US Standard Million Population, were 1077, 1248, and 1133 per 100,000, respectively. Infection was the most common principal diagnosis at the hospital stay during which the patient died in the MS cohort (43.1% vs. 26.3% and 24.0% in the DM and GHP groups, respectively). Other common principal diagnoses in the MS group included pulmonary (17.5%) and cardiovascular (12.1%) disease. Septicemia/sepsis/septic shock was a secondary diagnosis for 50.7% of patients with MS versus 36.0% and 31.0% of patients in the DM and GHP cohorts, respectively. Conclusions: Patients with MS had a shorter life span than patients with DM or the GHP and were more likely to have a principal diagnosis of infection at their final hospital stay. However, the database was limited to codes recorded in the hospital; diagnoses received outside the hospital were not captured. PMID:27252603

    Akenhead, R, Harley, J, and Tweddle, S. Examining the external training load of an English Premier League football team with special reference to acceleration. J Strength Cond Res 30(9): 2424-2432, 2016-Practitioners and coaches often use external training load variables such as distance run and the number of high-speed running (HSR) activities to quantify football training. However, an important component of the external load may be overlooked when acceleration activities are not considered. The aim of this study was to describe the within-microcycle distribution of external load, including acceleration, during in-season 1-game weeks in an elite football team. Global Positioning System technology was used to collect time-motion data from 12 representative 7-day microcycles across a competitive season (48 training days, 295 data sets). Training time, total distance (TD), high-speed running (HSR) distance (>5.8 m·s), sprint running distance (>6.7 m·s) and acceleration variables were recorded during each training session. Data were analysed for interday and interposition differences using mixed linear modeling. The distribution of external load was characterized by the second training day of the microcycle (5 days prematch) exhibiting the highest values for all variables of training load, with the fourth day (1 day prematch) exhibiting the lowest values. Central midfield players covered ∼8-16% greater TD than other positions excluding wide midfielders (p ≤ 0.03, d = 0.2-0.4) and covered ∼17% greater distance accelerating 1-2 m·s than central defenders (p = 0.03, d = 0.7). When expressed relative to training duration and TD, the magnitude of interday and interposition differences were markedly reduced (p = 0.03, d = 0.2-0.3). When managing the distribution of training load, practitioners should be aware of the intensity of training sessions and consider the density of external load within sessions. PMID:26817740

    This study investigated the evolution of physical and technical performances in the English Premier League (EPL), with special reference to league ranking. Match performance observations (n = 14,700) were collected using a multiple-camera computerised tracking system across seven consecutive EPL seasons (2006-07 to 2012-13). Final league rankings were classified into Tiers: (A) 1st-4th ranking (n = 2519), (B) 5th-8th ranking (n = 2965), (C) 9th-14th ranking (n = 4448) and (D) 15th-20th ranking (n = 4768). Teams in Tier B demonstrated moderate increases in high-intensity running distance while in ball possession from the 2006-07 to 2012-13 season (P < 0.001; effect size [ES]: 0.68), with Tiers A, C and D producing less pronounced increases across the same period (P < 0.005; ES: 0.26, 0.41 and 0.33, respectively). Large increases in sprint distance were observed from the 2006-07 to 2012-13 season for Tier B (P < 0.001; ES: 1.21), while only moderate increases were evident for Tiers A, C and D (P < 0.001; ES: 0.75, 0.97 and 0.84, respectively). Tier B demonstrated large increases in the number of passes performed and received in 2012-13 compared to 2006-07 (P < 0.001; ES: 1.32-1.53) with small-to-moderate increases in Tier A (P < 0.001; ES: 0.30-0.38), Tier C (P < 0.001; ES: 0.46-0.54) and Tier D (P < 0.001; ES: 0.69-0.87). The demarcation line between 4th (bottom of Tier A) and 5th ranking (top of Tier B) in the 2006-07 season was 8 points, but this decreased to just a single point in the 2012-13 season. The data demonstrate that physical and technical performances have evolved more in Tier B than any other Tier in the EPL and could indicate a narrowing of the performance gap between the top two Tiers.

    Acquiring accurate information on the spatio-temporal variability of soil moisture content (SM) and evapotranspiration (ET) is of key importance to extend our understanding of the Earth system's physical processes, and is also required in a wide range of multi-disciplinary research studies and applications. The utility and applicability of Earth Observation (EO) technology provides an economically feasible solution to derive continuous spatio-temporal estimates of key parameters characterising land surface interactions, including ET as well as SM. Such information is of key value to practitioners, decision makers and scientists alike. The PREMIER-EO project recently funded by High Performance Computing Wales (HPCW) is a research initiative directed towards the development of a better understanding of EO technology's present ability to derive operational estimations of surface fluxes and SM. Moreover, the project aims at addressing knowledge gaps related to the operational estimation of such parameters, and thus contribute towards current ongoing global efforts towards enhancing the accuracy of those products. In this presentation we introduce the PREMIER-EO project, providing a detailed overview of the research aims and objectives for the 1 year duration of the project's implementation. Subsequently, we make available the initial results of the work carried out herein, in particular, related to an all-inclusive and robust evaluation of the accuracy of existing operational products of ET and SM from different ecosystems globally. The research outcomes of this project, once completed, will provide an important contribution towards addressing the knowledge gaps related to the operational estimation of ET and SM. This project results will also support efforts ongoing globally towards the operational development of related products using technologically advanced EO instruments which were launched recently or planned be launched in the next 1-2 years.

    We read with interest the recent article written by Goto, Morris & Nevill: 'Match Analysis of U9 and U10 English Premier League Academy Soccer Players using a Global Positioning System: Relevance for Talent Identification and Development'. In summary, the authors reported time motion analysis data from match-play showing that players who were retained by their Academy covered a significantly greater distance overall and in low-speed running in comparison to peers who were released. Consequently, the authors discussed their results in the context of talent identification and development processes. In light of their findings and discussion, it is of our opinion that further debate in the context of the current body of literature is necessary. PMID:25148464

    Background Rotaviruses are the major cause of severe dehydrating diarrhea in children throughout the world. Enzyme immunoassays (EIA) have been the standard method for detection of rotavirus in stool specimens since the 1980s. The World Health Organization (WHO) Rotavirus Surveillance Network has proposed including three EIA kits in the WHO-GSM (Global Management System/Système Mondial de Gestion ) catalogue for easy procurement of EIA kits by participating rotavirus surveillance network laboratories. Objectives In this study, we conducted a comparative analysis of 3 commercially available enzyme immunoassay kits: PremierTM Rotaclone® (Meridian Bioscience, Inc.), ProSpecTTM (Oxoid, Ltd.) and RIDASCREEN® (R-biopharm AG) for rotavirus diagnostics. Study design Using reverse-transcriptase-PCR (RT-PCR) as the gold standard, the 3 EIA kits were evaluated by testing a stool panel consisting of 56 rotavirus-positive and 54 rotavirus negative samples. Results The sensitivities of the PremierTM Rotaclone®, ProSpecTTM and RIDASCREEN® kits were 76.8%, 75% and 82.1% respectively, but did not differ significantly. The specificity of all the 3 kits was 100%. The use of RT-PCR as a gold standard lowered the observed sensitivity of all 3 EIA kits but helps to reduce equivocal results that can be seen when another EIA or other non-molecular methods are used as the reference assay in comparison studies. Conclusion Our study found that all three kits are suitable for use by rotavirus surveillance programs. PMID:23850415

    Professional soccer players from the first team (1st team, n = 27), under twenty-one (U21, n = 21) and under eighteen (U18, n = 35) squads of an English Premier League soccer team were assessed for whole body and regional estimates of body composition using dual-energy X-ray absorptiometry (DXA). Per cent body fat was lower in 1st team (10.0 ± 1.6) compared with both U21 (11.6 ± 2.5, P = 0.02) and U18 (11.4 ± 2.6, P = 0.01) players. However, this difference was not due to variations (P = 0.23) in fat mass between squads (7.8 ± 1.6 v. 8.8 ± 2.1 v. 8.2 ± 2.4 kg, respectively) but rather the presence of more lean mass in 1st team (66.9 ± 7.1 kg, P < 0.01) and U21 (64.6 ± 6.5 kg, P = 0.02) compared with U18 (60.6 ± 6.3 kg) players. Accordingly, fat mass index was not different (P = 0.138) between squads, whereas lean mass index was greater (P < 0.01) in 1st team players (20.0 ± 1.1 kg · m(-2)) compared with U18 players (18.8 ± 1.4 kg · m(-2)). Differences in lean mass were also reflective of higher lean tissue mass in all regions, for example, upper limbs/lower limbs and trunk. Data suggest that training and nutritional interventions for younger players should therefore be targeted to lean mass growth as opposed to body fat loss. PMID:25686107

    The purpose of this study was to examine the match activity profile of U9 and U10 elite soccer players and to establish if there were any differences between players who were subsequently retained or released by their clubs. Such information should prove valuable in the design of training programs for these very young players and in the talent identification and development process. A Global Positioning System was used to analyze 2-4 interacademy 6-a-side matches of English Premier League Academy players (U9: N = 22 and U10: N = 12) who trained 3 times a week (4.5 hours). Speed zones were created based on 5 and 10-m sprint times, and an independent sample t-test was employed for a statistical analysis. Both squads covered ∼4,000 m in total or ∼4,700 m·h during a match (p = NS between squads), with the U10 squad tending to cover a greater distance at moderate (p = 0.10) and high speeds (p = 0.08) than the U9 squad. Retained group covered a greater distance than released group (retained vs. released: 4,478 ± 513 m vs. 4,091 ± 462 m, p < 0.05) during a match and covered a greater distance during low-speed running in absolute (1,226 ± 259 m vs. 1,005 ± 221 m, p < 0.05) and relative (1,325 ± 235 m·h vs. 1,132 ± 210 m·h, p < 0.05) terms. Thus, U9 and U10 players cover over 4000 m in match play, and those players who are retained by academies cover a greater distance in total and at low speeds (2.1-3.1 m·s). This information may support the preparation of squad training programs and the talent identification and development process. PMID:23799422

    Muscle glycogen is the predominant energy source for soccer match play, though its importance for soccer training (where lower loads are observed) is not well known. In an attempt to better inform carbohydrate (CHO) guidelines, we quantified training load in English Premier League soccer players (n = 12) during a one-, two- and three-game week schedule (weekly training frequency was four, four and two, respectively). In a one-game week, training load was progressively reduced (P < 0.05) in 3 days prior to match day (total distance = 5223 ± 406, 3097 ± 149 and 2912 ± 192 m for day 1, 2 and 3, respectively). Whilst daily training load and periodisation was similar in the one- and two-game weeks, total accumulative distance (inclusive of both match and training load) was higher in a two-game week (32.5 ± 4.1 km) versus one-game week (25.9 ± 2 km). In contrast, daily training total distance was lower in the three-game week (2422 ± 251 m) versus the one- and two-game weeks, though accumulative weekly distance was highest in this week (35.5 ± 2.4 km) and more time (P < 0.05) was spent in speed zones >14.4 km · h(-1) (14%, 18% and 23% in the one-, two- and three-game weeks, respectively). Considering that high CHO availability improves physical match performance but high CHO availability attenuates molecular pathways regulating training adaptation (especially considering the low daily customary loads reported here, e.g., 3-5 km per day), we suggest daily CHO intake should be periodised according to weekly training and match schedules.

    Purpose To systematically review the scientific level of evidence for the ‘Top 3’ risk factors, screening tests and preventative exercises identified by a previously published survey of 44 premier league football (soccer) teams. Also, to provide an overall scientific level of evidence and graded recommendation based on the current research literature. Methods A systematic literature search (Pubmed [MEDLINE], SportDiscus, PEDRO and Cochrane databases). The quality of the articles was assessed and a level of evidence (1++ to 4) was assigned. Level 1++ corresponded to the highest level of evidence available and 4, the lowest. A graded recommendation (A: strong, B: moderate, C: weak, D: insufficient evidence to assign a specific recommendation) for use in the practical setting was given. Results Fourteen studies were analysed. The overall level of evidence for the risk factors previous injury, fatigue and muscle imbalance were 2++, 4 and ‘inconclusive’, respectively. The graded recommendation for functional movement screen, psychological questionnaire and isokinetic muscle testing were all ‘D’. Hamstring eccentric had a weak graded ‘C’ recommendation, and eccentric exercise for other body parts was ‘D’. Balance/proprioception exercise to reduce ankle and knee sprain injury was assigned a graded recommendation ‘D’. Conclusions The majority of perceptions and practices of premier league teams have a low level of evidence and low graded recommendation. This does not imply that these perceptions and practices are not important or not valid, as it may simply be that they are yet to be sufficiently validated or refuted by research. PMID:25576530

    Some odorous products as tetrahydrothiophene (THT) whose odour is perceived at low concentration, are injected in natural gas in order to odorize it. This artificial odorization allows to detect immediately any gas leak in atmosphere. The authors have measured the equilibrium compositions of gaseous phases for binaires THT-CH4, THT-N2 and THT-CO2 in the transport and distribution conditions of natural gas [ {1 < P (bar) < 60} and {-30 < t(^circ C) < 50}] . For this purpose an experimental device based on a principle of dynamic saturation coupled with an on-line gas chromatographic analysis was assembled and adjusted. Additional thermodynamic properties are required to know the molar composition of vapour phase. The authors have measured the THT vapour pressure and estimated the second virial coefficients. For the estimations it was necessary to know the critical values and the acentric factor that have been calculated with various correlations. Certains produits comme le tétrahydrothiophène (THT), dont l'odeur est perçue à faible teneur, sont injectés dans le gaz naturel en vue de son odorisation. Cette odorisation artificielle rend toute fuite éventuelle de gaz dans l'atmosphère immédiatement détectable. Les auteurs ont mesuré les compositions à l'équilibre des phases gaseuses des binaires THT-CH4, THT-N02 et THT-CO2 dans les conditions de transport et de distribution du gaz [ {1 < P (bar) < 60} and {-30 < t(^circ C) < 50}] . Dans ce but, un dispositif expérimental original basé sur un principe de saturation dynamique avec analyse chromatographique en ligne de la phase vapeur a été réalisé et mis au point. Des grandeurs thermodynamiques supplémentaires sont nécessaires pour atteindre les compositions molaires de la phase vapeur. Les auteurs ont mesuré les pressions de vapeur du THT et estimé les seconds coefficients du viriel. Ces estimations font intervenir les grandeurs critiques et facteurs acentriques qui ont été calculés par diverses

    Introduction Le but de cette étude était de présenter les premiers résultats de diagnostic anténatal de la trisomie 21 par la technique d'hybridation in situ en fluorescence (FISH) au Maroc et discuter son intérêt dans le diagnostic rapide de cette aneuploïdie. Méthodes Ce travail a été réalisé chez 23 femmes avec des grossesses à haut risque de trisomie 21. La moyenne d’âge des gestantes étaient de 37,43 ans avec des extrêmes de 21 et 43 ans. Toutes étaient musulmanes mariées, mariage légitimé par la Charia, dont trois mariages consanguins, sauf une originaire de la République Démocratique du Congo qui était chrétienne et concubine. La majorité des femmes étaient fonctionnaires et avaient un niveau de scolarisation moyen à élevé. Toutes les patientes ont bénéficié d'une consultation de génétique médicale au cours de laquelle il leur a été donné des informations sur la technique, son intérêt et ses limites. Il s'agit de femmes enceintes qui avaient soit un âge maternel élevé ou des signes d'appel échographiques et/ ou biochimiques. Une des patientes était porteuse d'une translocation robertsonienne t(14;21) équilibrée. Une amniocentèse a été réalisée chez toutes les gestantes et aucun avortement n'a était induit par ce geste invasif. L’âge gestationnel moyen à la première consultation était de 14 semaines d'aménorrhée (SA) et à l'amniocentèse était de 16 SA et 5 jours. L'analyse FISH a été réalisée, après consentement des couples, sur des cellules non cultivées à partir des échantillons de liquides amniotiques, en utilisant des sondes spécifiques du chromosome 21. Résultats Parmi les 23 patientes qui ont bénéficiées d'un diagnostic anténatal de la trisomie 21 par la technique FISH, nous avons pu rassurer 21 d'entre elles, et nous avons détecté deux cas de trisomie 21 fœtal. Conclusion La technique FISH permet un diagnostic anténatal rapide, en moins de 48h, de la trisomie 21 sur

    Gould, Charles

    Dans ce travail on utilise une nouvelle geometrie pour augmenter le controle sur le nombre d'electrons contenus dans une boite quantique laterale, et ainsi atteindre un regime de petit nombre d'electrons. Ces echantillons permettent une etude du blocage de Coulomb quand les electrons sont injectes a partir d'un gaz electronique a deux dimensions (2DEG). Les mesures a faible champ magnetique demontrent la grande flexibilite des echantillons et montrent que l'on peut faire varier le nombre d'electrons dans une boite quantique a partir de plus de 40 electrons jusqu'a un seul electron, ce qui est assez courant dans les boites quantiques verticales, mais ce qui n'avait jamais ete reussi dans une boite quantique laterale. Nos resultats montrent egalement que dans les boites quantiques laterales il est possible de determiner le spin du niveau qui participe au transport a l'aide du phenomene de blocage de spin. De plus, dans certaines circonstances il est meme possible de determiner le spin total de la boite quantique, ce qui peut avoir des applications pratiques dans des domaines tels l'informatique quantique. Les mesures dans le regime de renversement de spin a un champ magnetique plus eleve montrent l'importance des correlations electrons---electrons dans ces boites quantiques, qui menent a des depolarisations et a des structures de spins qui ont un effet sur le transport. En particulier, ces correlations menent a l'existence de niveaux excites de basse energie qui causent une dependance anormale de l'amplitude des pics de blocage de Coulomb en fonction de la temperature. Nos experiences demontrent egalement la possibilite d'utiliser ces boites quantiques comme sondes pour etudier les proprietes du bord d'un 2DEG. Une voie de recherche a etre exploree.

    The title of this lecture abstracts only a part of it : the importance in astrophysics of the study of non-LTE situations has become considerable, as well in the stellar atmospheres as, still more, in the study of fortuitous coincidences as a mechanism of formation of emission line nebular spectra, or of molecular interstellar « masers ». Another part of this talk underlines the role of Kastler in his time, and describes his warm personality through his public reactions in front of the nuclear armement, of the Viet-Nam and Algerian wars, of the problems of political refugees... Kastler was a great scientist ; he was also a courageous humanist. 1976 : Les accords nucléaires du Brésil : allocution d'ouverture (19 mars).

Une autre partie de cet exposé souligne le rôle de Kastler dans son époque, et décrit sa personnalité généreuse à travers ses réactions publiques face à l'armement nucléaire, aux guerres de Viet-Nam et d'Algérie, aux problèmes des réfugiés politiques... Kastler était un grand savant, mais aussi un homme courageux.

    Voice source characteristics as derived from inverse filtering were analyzed in 6 country singers' speech and singing. Results showed that the closed quotient varied systematically with vocal loudness, and that glottal compliance (the ratio between transglottal AC volume displacement and subglottal pressure) decreased with increases in fundamental frequency but remained unaffected by vocal loudness. No striking differences were found in source characteristics between speech and singing within subjects. The degree of phonatory press, as judged by a panel of 19 expert listeners, appeared related to the range in which the singer was singing and to the sound pressure level gain from a doubling of subglottal pressure.

    Methane number and Lower Heating Value ( LHV) of natural gas are determined by the online measurement of thermal conductivity at two different temperatures. Natural gas is first considered as a ternary mixture of the most important components. A pseudo-ternary composition can then be calculated, using the thermal conductivity formula for mixtures derived from kinetic theory. A non-linear system is solved numerically using the Newton-Raphson method. A sensor based on thermal conductivity measurement has been developed and tested successfully for many natural gas compositions. To cite this article: C. Rahmouni et al., C. R. Mecanique 331 (2003).

    Two billion years ago, the increase of oxygen in atmosphere and the high 235U/ 238U uranium ratio (>3%) made possible the occurrence of natural nuclear reactors on Earth. These reactors are considered to be a good natural analogue for nuclear waste disposal. Their preservation during such a long period of time is mainly due to the geological stability of the site, the occurrence of clays surrounding the reactors and acting as an impermeable shield, and the occurrence of organic matter that maintained the environment in reducing conditions, favourable for the stability of uraninite. Hydrogeochemical studies and modelling have shown the complexity of the geochemical system at Oklo and Bangombé (Gabon) and the lack of precise data about uranium and fission products retention and migration mechanisms in geological environments.

    A strong foundation of basic and applied research documents that the estuarine fish Fundulus heteroclitus and related species are unique laboratory and field models for understanding how individuals and populations interact with their environment. In this paper we summarize an extensive body of work examining the adaptive responses of Fundulus species to environmental conditions, and describe how this research has contributed importantly to our understanding of physiology, gene regulation, toxicology, and ecological and evolutionary genetics of teleosts and other vertebrates. These explorations have reached a critical juncture at which advancement is hindered by the lack of genomic resources for these species. We suggest that a more complete genomics toolbox for F. heteroclitus and related species will permit researchers to exploit the power of this model organism to rapidly advance our understanding of fundamental biological and pathological mechanisms among vertebrates, as well as ecological strategies and evolutionary processes common to all living organisms.

  15. PECVD de composes de silicium sur polymeres: Etude de la premiere phase du depot

    NASA Astrophysics Data System (ADS)

    Dennler, Gilles

    Since their first introduction in the early 90's, transparent barriers against oxygen and/or water vapor permeation through polymers, such as SiO 2, are the object of increasing interest in the food and pharmaceutical packaging industries, and more recently for the encapsulation of organic-based displays. It is now well known that these thin layers possess barrier properties only if they are thicker than a certain critical thickness, dc. For example, dc is around 12 nm in the case of SiO2 on KaptonRTM PI; below this value, the measured "Oxygen Transmission Rate" (OTR, in standard cm3/m2/day/bar) is roughly the same as that of the uncoated polymer. Until now, no detailed research has been carried out to explain this observation, but a hypothesis was proposed in the literature, based on island-like growth structure of the coating for d ≤ dc. According to this hypothesis, the surface energy of the polymeric substrates is so low that the Volmer-Weber (island-coalescence) growth mode occurs. We have aimed to verify this explanation, that is, to study the initial phase of silicon-compound (SiO2 and SiN) growth on four different polymeric substrates, namely polyimide (KaptonRTM PI), polycarbonate (LexanRTM PC), polypropylene (PP), and polyethyleneterephthalate (MylarRTM PET). Three different deposition methods were used, namely reactive evaporation of SiO, radio-frequency (RF) Plasma Enhanced Chemical Vapor Deposition (RF PECVD), and Distributed Electron Cyclotron Resonance (DECR) PECVD. In this latter case, the substrates were placed in three different positions: (i) in the active glow zone, (ii) downstream, and (iii) downstream, but shielded from photon emission (e.g. VUV) from the plasma. Angle-Resolved X-Ray Photoelectron Spectroscopy (ARXPS), Rutherford Backscattering Spectroscopy (RBS), and Scanning Electron Microscopy (SEM), the latter performed after Reactive Ion Etching (RIE) by oxygen plasma, revealed that growth indeed occurs in a Volmer-Weber mode in the case of evaporated films. The island coalescence was observed to occur at d = 1.2 nm, at which point the sticking coefficient of precursor species changes drastically. Finally, we have investigated the presence of an "interphase" between deposited coatings and the polymeric substrate. (Abstract shortened by UMI.)

  18. Softform Premier Active mattress: a novel step-up/step-down approach.

    PubMed

    Thompson, Geoff

    In the UK it is estimated that as many as 412,000 patients who are already ill will develop pressure ulcers (Bennett et al, 2004), which are an unnecessary and expensive complication to treat (Hitch, 1995). One way to try and reduce these risks is by investing in suitable mattresses. The author's investigations into existing mattress stock in the years 1996-97 illustrated the inadequacy of the NHS standard mattress (Santy, 1995; Fox, 1997). Investigators (e.g. Rithalia, 1996) were recognizing the inadequacy of the pink marbled standard NHS foam mattress for pressure reduction (Medical Device Directorate, 1993; Dunford, 1994) which included reports necessary to help develop guidelines in pressure ulcer prevention and management (Coull, 2004), as well as make value-for-money recommendations about product purchases (Fletcher et al, 1994; Value For Money Update, 1994; Cullum et al, 1995).

    Professional soccer players are exposed to large amounts of physiological and psychological stress, which can increase infection risk and threaten availability for training and competition. Accordingly, it is important for practitioners to implement strategies that support player well-being and prevent illness. This case study demonstrates how a scientifically supported and practically applicable nutrition and lifestyle strategy can reduce infection incidence in an illness-prone professional soccer player. In the 3 months before the intervention, the player had 3 upper-respiratory tract infections (URTIs) and subsequently missed 3 competitive matches and 2 weeks' training. He routinely commenced morning training sessions in the fasted state and was estimated to be in a large daily energy deficit. Throughout the 12-week intervention, the amount, composition, and timing of energy intake was altered, quercetin and vitamin D were supplemented, and the player was provided with a daily sleep and hygiene protocol. There was a positive increase in serum vitamin D 25(OH) concentration from baseline to Week 12 (53 n·mol-1 to 120 n·mol-1) and salivary immunoglobulin-A (98 mg·dl-1 to 135 mg·dl-1), as well as a decline in the number of URTI symptoms (1.8 ± 2.0 vs. 0.25 ± 0.5 for Weeks 0-4 and Weeks 8-12, respectively). More important, he maintained availability for all training and matches over the 12-week period. We offer this case study as a real-world applied example for other players and practitioners seeking to deploy nutrition and lifestyle strategies to reduce risk of illness and maximize player availability.

    Background As preventing cancer with the help of a vaccine is a comparatively new concept, awareness and education about it will have important implication in the implementation of this strategy. Materials and Methods Present explorative questionnaire based survey included 618 MBBS students for final analysis. Results Majority of participants (89.6%) were well aware of the preventable nature of cervical cancer. Most of them (89.2%) knew that necessary factor responsible for cervical cancer is infection with high risk HPV. Awareness regarding the availability of vaccine against cervical cancer was 75.6%. Females had a better awareness regarding availability of vaccine, target population for vaccination and about the catch up program. Overall acceptance of HPV vaccine among the population studied was 67.8%. Medical teaching had a definitive impact on the understanding of this important public health issue. Females seemed to be more ready to accept the vaccine and recommend it to others. For our study population the most common source of information was medical school teaching. Majority of participants agreed that the most important obstacle in implementation of HPV vaccination program in our country is inadequate information and 86.2% wanted to be educated by experts in this regard. Conclusion HPV vaccine for primary prevention of cervical cancer is a relatively new concept. Health professional will be able to play a pivotal role in popularizing this strategy. PMID:22859950

    Human chromosomes 1q21–q25, 6p21.3–22.2, 9q33–q34, and 19p13.1–p13.4 carry clusters of paralogous loci, to date best defined by the flagship 6p MHC region. They have presumably been created by two rounds of large-scale genomic duplications around the time of vertebrate emergence. Phylogenetically, the 1q21–25 region seems most closely related to the 6p21.3 MHC region, as it is only the MHC paralogous region that includes bona fide MHC class I genes, the CD1 and MR1 loci. Here, to clarify the genomic structure of this model MHC paralogous region as well as to gain insight into the evolutionary dynamics of the entire quadriplication process, a detailed analysis of a critical 1.7 megabase (Mb) region was performed. To this end, a composite, deep, YAC, BAC, and PAC contig encompassing all five CD1 genes and linking the centromeric +P5 locus to the telomeric KRTC7 locus was constructed. Within this contig a 1.1-Mb BAC and PAC core segment joining CD1D to FCER1A was fully sequenced and thoroughly analyzed. This led to the mapping of a total of 41 genes (12 expressed genes, 12 possibly expressed genes, and 17 pseudogenes), among which 31 were novel. The latter include 20 olfactory receptor (OR) genes, 9 of which are potentially expressed. Importantly, CD1, SPTA1, OR, and FCERIA belong to multigene families, which have paralogues in the other three regions. Furthermore, it is noteworthy that 12 of the 13 expressed genes in the 1q21–q22 region around the CD1 loci are immunologically relevant. In addition to CD1A-E, these include SPTA1, MNDA, IFI-16, AIM2, BL1A, FY and FCERIA. This functional convergence of structurally unrelated genes is reminiscent of the 6p MHC region, and perhaps represents the emergence of yet another antigen presentation gene cluster, in this case dedicated to lipid/glycolipid antigens rather than antigen-derived peptides.

    Metals are known to have deleterious effects on aquatic ecosystems, so monitoring the bioaccumulation of these pollutants is important for the assessment of potential impacts. The aim of the study was therefore to determine the degree to which aquatic biota in selected rivers of the world renowned Kruger National Park (KNP) are exposed to metals entering from the catchments outside the KNP and to determine how these metal levels reflect what is occurring within the environment. Many of these rivers have never previously been assessed and those which have, have not been assessed within the past two decades. Tigerfish (Hydrocynus vittatus) is an economically important apex predator and was selected as the bioindicator for this study. Fish were sampled from the KNP sections of the Luvuvhu, Letaba and Olifants Rivers during the high and low flow periods from 2009 to 2011. The analysis of various metals from the aforementioned systems revealed spatial and temporal related variation in metal level patterns of the chosen bioindicator, with concentrations in fish from the Olifants River>Letaba River>Luvuvhu River and 2009>2010>2011. Although there were differences between rivers, metal concentrations were comparable and indicate that all of the studied KNP rivers, even those considered to be in a natural state are affected to some degree by anthropogenic activities. However, concentrations found during this study were much lower than previous studies in the area, as well as contaminated sites across the world, but were higher than concentrations in fish from contaminated sites in the Vaal River, South Africa. Bioaccumulated metals showed no correlation to metals in the water column, but some were correlated to sediment metal concentrations and the contamination and bioavailability of these metals within the sediments. This is of concern when managing the water resources of the conservation area since the contaminants enter the park from outside the borders and pose potential risks to the mandated conservation of aquatic biota within the KNP.

    The sandy materials underlying the Fontainebleau Forest (Paris Basin) are often podzolised. Several radiocarbon datings reveal different periods of podzolisation: during the first millenary before Christ (aliotic podzols, often humic, over Stampian sands, very quartzic and acid - certainly under heather and pines); from 10th to 12th centuries AD (humoferruginous podzols with Bh and Bs partially indurated, over blown sands, poor in fine particles - probably under heather); from 16th to 17th centuries AD (ochrepodzolic soils on blown sands, richer in fine particles than precedent, and humic podzols upon eroded Stampian sands); more recently, not precisely dated (ochrepodzolic soils or podzols with loose Bh over blown sands, relatively rich in fine particles, sometimes under leafed trees).

    Natural quartz crystals coming from Madagascar, Angola, Brazil, and Spain were studied by EPR after β irradiation in order to characterise the paramagnetic centres due to impurities, and examine in which way their relative proportion could constitute a useful criterion for origin researches. In all our samples, EPR experiments revealed germanium centres [GeO 4/M +]° with M = Li or Na, aluminium ones [AlO 4/h]° and two titanium centres ([TiO 4/H +]° and [TiO 4/M +]°) also appeared, except for samples coming from Spain. The comparison of the relative concentrations of paramagnetic species led us on to draw diagrams that allowed distinguishing the origins of the studied samples using only EPR spectra.

  19. Evaluation de l'impact du vent et des manoeuvres hydrauliques sur le calcul des apports naturels par bilan hydrique pour un reservoir hydroelectrique

    NASA Astrophysics Data System (ADS)

    Roy, Mathieu

    Natural inflow is an important data for a water resource manager. In fact, Hydro-Quebec uses historical natural inflow data to perform a daily prediction of the amount of water that will be received in each of its hydroelectric reservoirs. This prediction allows the establishment of reservoir operating rules in order to optimize hydropower without compromising the safety of hydraulic structures. To obtain an accurate prediction, it follows that the system's input needs to be very well known. However, it can be very difficult to accurately measure the natural supply of a set of regulated reservoirs. Therefore, Hydro-Quebec uses an indirect method of calculation. This method consists of evaluating the reservoir's inflow using the water balance equation. Yet, this equation is not immune to errors and uncertainties. Water level measurement is an important input in order to compute the water balance equation. However, several sources of uncertainty including the effect of wind and hydraulic maneuvers can affect the readings of limnimetric gages. Fluctuations in water level caused by these effects carry over in the water balance equation. Consequently, natural inflow's signal may become noisy and affected by external errors. The main objective of this report is to evaluate the uncertainty caused by the effects of wind and hydraulic maneuvers on water balance equation. To this end, hydrodynamic models of reservoirs Outardes 4 and Gouin were prepared. According to the literature review, wind effects can be studied either by an unsteady state approach or by assuming steady state approach. Unsteady state simulation of wind effects on reservoir Gouin and Outardes 4 were performed by hydrodynamic modelling. Consideration of an unsteady state implies that the wind conditions vary throughout the simulation. This feature allows taking into account temporal effect of wind duration. In addition, it also allows the consideration of inertial forces such as seiches which are caused by wind conditions that can vary abruptly. Once the models were calibrated, unsteady state simulations were conducted in closed system where unsteady observed winds were the only forces included. From the simulated water levels obtained at each gage, water balance equation was calculated to determine the daily uncertainty of natural inflow in unsteady conditions. At Outardes 4, a maximum uncertainty of 20 m3/s was estimated during the month of October 2010. On the other hand, at the Gouin reservoir, a maximum uncertainty of 340m3/s was estimated during the month of July 2012. Steady state modelling is another approach to evaluate wind effect uncertainty in the water balance equation. This type of approach consists of assuming that the water level is instantly tilted under the influence of wind. Hence, temporal effect of wind duration and seiches cannot be taken into account. However, the advantage of steady state modelling is that it's better suited than unsteady state modelling to evaluate wind uncertainty in real time. Two steady state modelling methods were experimented to estimate water level difference between gages in function of wind characteristics: hydrodynamic modelling and non-parametric regression. It has been found that non-parametric models are more efficient when it comes to estimate water level differences between gages. However, the use of hydrodynamic model demonstrated that to study wind uncertainty in the water balance equation, it is preferable to assess wind responses individually at each gage instead of using water level differences. Finally, a combination method of water level gages observations has been developed. It allows reducing wind/hydraulic maneuvers impacts on the water balance equation. This method, which is applicable in real time, consists of assigning a variable weight at each limnimetric gages. In other words, the weights automatically adjust in order to minimize steady state modeled wind responses. The estimation of hydraulic maneuvers has also been included in the gage weight adjustment. It has been found that this new combination method allows the correction of noisy natural inflow signal under wind and hydraulic maneuvers effects. However, some fluctuations persist which reflects the complexity of correcting these effects on a real time based daily water balance equation. (Abstract shortened by UMI.).

    D'abondantes recherches ont demontre que la reussite a la tache d'horizontalite des liquides est en moyenne plus elevee chez les individus de sexe masculin que chez ceux de sexe feminin. Deux facteurs principaux ont ete proposes: il s'agit de la connaissance du principe physique de l'invariance de l'orientation des liquides et de certaines habiletes perceptives d'ordre visuel. Le but de la presente recherche est d'etablir la duree detaillee de la resolution de la tache d'horizontalite des liquides chez 185 filles et 180 garcons, ages de 15 a 19 ans et repartis en 8 groupes. Dans une version informatisee, le premier groupe trace la position de la surface de l'eau a l'interieur d'un contenant dans diverses inclinaisons et le deuxieme evalue si l'orientation d'une ligne y represente bien cette position; le troisieme groupe trace une horizontale dans un rectangle et le quatrieme juge si la ligne illustree y est bien horizontale. Quatre autres groupes executent respectivement les memes taches dans la version classique papier-crayon. Le temps accorde a la reflexion avant de commencer le trace, le temps de tracage comme tel et le temps de verification du trace complete sont calcules. Chez les groupes qui evaluent l'orientation d'une ligne sur support informatique, le temps requis pour y parvenir est note. Enfin, un questionnaire estime si les participants connaissent ou non le principe physique d'invariance de l'orientation de la surface d'un liquide. Les resultats revelent que cette connaissance est plus frequente chez les garcons dans l'ensemble des groupes. Dans le cas ou les sujets ont a tracer une ligne, les filles reussissent moins d'essais que les garcons s'il faut, sur support informatique, tracer la surface de l'eau dans un contenant incline ou a l'horizontale. Il en va de meme s'il faut, sur support papier, tracer une horizontale dans un contenant incline. Le trace de la surface de l'eau est plus exact chez les sujets connaissant le principe d'invariance et l

    Description of complex systems by Density functional theory is treated in this thesis. First, the Density functional theory and a few functionals used to simulate cristals are presented. Specifically, the LDA and GGA functionnals are described and their limits are exposed. Furthermore, the Hubbard model as well as the LDA+U functionnal are addressed in this chapter. These methods enable the study of highly correlated materials. Then, results obtained on polymers are summarized in two articles. The first one treats the band gap variation of ladder-type polymers compared to non ladder type ones. The second article considers small band gap polymers. In this case, it will be shown that an hybrid functional, which contains exact exchange, is required to describe the electronic properties of the polymers under study. Finally, the last chapter address the study of cuprates superconductors. The LDA+U can account for the localization of electrons in copper orbitals. Consequently, a study of the impact of this functionnal on electronic properties of cuprates is conducted. The chapter is ended by an article treating magnetic orders in doped La 2CuO4. Supplementary materials of the second article and a description of the theory of superconductivity of Bardeen, Cooper and Schrieffer are put in annex. Keywords : Electronic correlation, DFT, LDA+U, cuprates, polymers, magnetic orders

    Summary Background The prevalence of male obesity is increasing but few men take part in weight loss programmes. We assessed the effect of a weight loss and healthy living programme on weight loss in football (soccer) fans. Methods We did a two-group, pragmatic, randomised controlled trial of 747 male football fans aged 35–65 years with a body-mass index (BMI) of 28 kg/m2 or higher from 13 Scottish professional football clubs. Participants were randomly assigned with SAS (version 9·2, block size 2–9) in a 1:1 ratio, stratified by club, to a weight loss programme delivered by community coaching staff in 12 sessions held every week. The intervention group started a weight loss programme within 3 weeks, and the comparison group were put on a 12 month waiting list. All participants received a weight management booklet. Primary outcome was mean difference in weight loss between groups at 12 months, expressed as absolute weight and a percentage of their baseline weight. Primary outcome assessment was masked. Analyses were based on intention to treat. The trial is registered with Current Controlled Trials, number ISRCTN32677491. Findings 374 men were allocated to the intervention group and 374 to the comparison group. 333 (89%) of the intervention group and 355 (95%) of the comparison group completed 12 month assessments. At 12 months the mean difference in weight loss between groups, adjusted for baseline weight and club, was 4·94 kg (95% CI 3·95–5·94) and percentage weight loss, similarly adjusted, was 4·36% (3·64–5·08), both in favour of the intervention (p<0·0001). Eight serious adverse events were reported, five in the intervention group (lost consciousness due to drugs for pre-existing angina, gallbladder removal, hospital admission with suspected heart attack, ruptured gut, and ruptured Achilles tendon) and three in the comparison group (transient ischaemic attack, and two deaths). Of these, two adverse events were reported as related to participation in the programme (gallbladder removal and ruptured Achilles tendon). Interpretation The FFIT programme can help a large proportion of men to lose a clinically important amount of weight; it offers one effective strategy to challenge male obesity. PMID:24457205

    With the second highest gross domestic product in Africa, South Africa is known to have a high pesticide usage, including the highly persistent and banned group of organochlorine pesticides (OCPs). South Africa is also one of few countries to still actively spray DDT as malaria vector control. The aim of the study was to determine the degree to which aquatic biota in selected rivers of the world renowned Kruger National Park (KNP) are exposed to by use of OCPs in the catchments outside the KNP and how this exposure relates to human health. Tigerfish (Hydrocynus vittatus) are economically important apex predators and was selected as bioindicator for this study. Fish were sampled from the KNP sections of the Luvuvhu, Letaba and Olifants rivers during the high and low flow periods from 2010 to 2011 within the KNP and 19 OCPs were determined in muscle tissue using GC-ECD techniques. Significant flow related and spatial OCP bioaccumulation was observed. Tigerfish from the Luvuvhu River displayed the highest OCP bioaccumulation. Concentrations of the majority of the OCPs including the DDTs were the highest levels ever recorded from South African freshwater systems and in many cases the concentrations were higher than most contaminated areas from around the world. The concentrations found in H. vittatus muscle also exceeded maximum residue levels in edible fat as set by the European Union. The health risk assessment also demonstrated that the levels of OCPs pose very high cancer risks to the local populations consuming tigerfish, as high as 2 in 10 increased risk factor. This is of concern not only when managing the water resources of the conservation area but also for surrounding communities consuming freshwater fish. Contaminants enter the park from outside the borders and pose potential risks to the mandated conservation of aquatic biota within the KNP. PMID:26845188

    13C NMR spectra of the title compounds have been fully assigned. The results have been compared with those relative to other chalcogenated compounds, such as anisole, phenyl benzoate, benzofuran,… and their analogs. In chalcogenochromones and -coumarines, the heteroatom lone pair delocalization spreads to some extent over the heterocyclic part of the molecules, while in chalcogenochromanones and -indoxyles, it only extends to the homocycle. This electronic effect seems also to affect the heavy atom effect exhibited by Te-containing compounds.

    Girard Baril, Frederique

    Pour etablir le comportement pharmacocinetique de nouveaux radiotraceurs en imagerie moleculaire, il est necessaire d'approfondir l'analyse realisee a partir d'une image par l'ajout d'une mesure dynamique de la radioactivite dans le sang. L'Universite de Sherbrooke developpe presentement une plateforme microfluidique d'echantillonnage et d'analyse permettant la mesure de la radioactivite du plasma en temps reel. L'objectif du present projet de maitrise etait de realiser le composant optoelectronique responsable de la detection des positrons et de l'integrer a la puce microfluidique. L'option retenue a ete l'utilisation de photodiodes PIN en silicium. Un procede de fabrication, ainsi qu'une serie de photomasques ont ete developpes afin de produire une premiere iteration de prototypes. Les detecteurs ont ete concus de maniere a optimiser leur sensibilite en fonction du type de rayonnement a detecter. En effet, la region de detection doit etre suffisamment epaisse et sensible pour absorber le maximum de particules energetiques. Egalement, il est essentiel de minimiser le courant de fuite en noirceur afin d'obtenir un photocourant directement proportionnel a l'energie des radiations incidentes. Les caracteristiques electriques obtenues avec les premiers detecteurs ont ete demontrees proches des performances de detecteurs commerciaux similaires. De plus, il a ete possible d'integrer un canal microfluidique au substrat contenant les photodiodes et d'en realiser l'encapsulation sans alterer les performances electriques initiales des detecteurs. Une courbe de l'activite radioactive du 18F a ete mesuree, celle-ci se comparant a l'activite theorique associee a ce radioisotope communement utilise en TEP. Enfin, un spectre en energie des emissions radiatives du 18F a ete mesure et compare aux performances de systemes utilisant des photodiodes commerciales. Il a ete demontre que le prototype offrait un rapport signal sur bruit similaire aux systemes bases sur des photodiodes

    representations finies des groupes de de Sitter, en utilisant des methodes deja connues. Les deux derniers chapitres sont des ecrits originaux qui, contrairement a tous les articles precedents, necessitent des modifications majeures avant d'etre soumis pour publication. Comme ils sont relies au sujet general de cette these, nous avons cru bon de les y inclure. Le premier d'entre eux porte sur une interpretation des geometries de Cayley-Klein en termes des contractions graduees. Ces travaux s'inserent naturellement dans le cadre de cette these puisque les resultats que nous y obtenons contiennent la plupart des groupes cinematiques comme cas particuliers de geometries a quatre dimensions. Pour clore le tout, nous considerons dans le chapitre 8 l'application des contractions traditionnelles aux equations differentielles. Plus precisement, nous nous interessons a la contraction des equations differentielles invariantes sous deux groupes reliees par contraction: so(2,1) (de Sitter en 1 + 1 dimensions) et p(1,1) (Poincare en 1 + 1 dimensions). A notre connaissance, cet article constitue le premier pas dans cette direction. Nous y suggerons une demarche vers une generalisation. La methode originale de contraction graduee present de nombreuses perspectives de recherches, d'interet autant mathematique que physique. Nous en discutons brievement dans le chapitre 9.

    The eastwards motion of the Caribbean plate is supposed to be related to a Cretaceous flip of subduction from eastwards to westwards vergence. However, we do not observe on the seismic profiles recorded during the CASIS 2 cruise any evidence of subduction beneath the Aves Ridge and Nicaragua Rise. Aves volcanic arc has been probably formed after the collision of the Caribbean volcanic plateau as shown by a wedge of volcanic-clastic sediments imaged by the seismic cruise CASIS 2. A recent left-lateral transtensional tectonics is observed in the lower Nicaragua Rise; the Colombia basin might have a motion towards the northeast relative to the rise.

    The open-air site of Holon (Israel), dated to an age of 200 000 years has yielded a large Acheulean bone and lithic assemblage. The association between the lithics and fauna clearly demonstrates that Hominids were the prime agents in creating the assemblage. The site of Holon plays a major role in understanding the Lower Palaeolithic of the Levantine coastal area.

    La cytogénétique constitue un outil indispensable pour le diagnostic et le pronostic de la leucémie aigue myéloïde (LAM). La t(8;16)(p11;p13) est rare au cours de cette pathologie. Nous décrivons le cas d'une patiente de 22 ans, admise pour un syndrome d'insuffisance médullaire complet associé à une altération de l’état général. L'examen clinique initial montrait un purpura ecchymotique diffus et des adénopathies latérocérvicales centimétriques bilatérales. L'hémogramme avait montré une anémie à 7,6g /dl normochrome normocytaire, des globules blancs à 87,8×109/L, 15% de polynucléaires neutrophiles, 60% de blastes, 24% de lymphocytes, 1% de Monocytes et 65×109/L de plaquettes. Le myélogramme avait objectivé une LAM1. Sur l'immunophenotypage les marqueurs positifs étaient le CD33 (99%), le CD15 (73%), le CD38 (95%) et l'HLA-DR (88%), les marqueurs monocytoïdes CD14 et CD64 étaient positifs, le CD34, les marqueurs lymphopïdes, la MPO (26%) et le CD13 (2%) étaient négatifs. Le caryotype avait montré: t(8,16)(p11, p13) add16 (20/20). L'inversion du chromosome 16 recherchée par FISH était négative. Le traitement avait consisté en 2 cures d'induction et 2 cures de consolidation selon le protocole national de traitement des LAM (Cytarabine, daunorubicine, etoposide), la rémission complète avait été obtenue en fin d'induction I, maintenue 9 mois suivie d'une rechute; Vu l'absence de possibilité d'une allogreffe, un traitement palliatif a été instauré, la malade est décédée de sa maladie un mois après la rechute. Notre cas se présente comme les cas décrits dans la littérature avec des données clinico- biologiques particulières. PMID:26327984

  9. Effet Hall et Magnetisme des Alliages Amorphes Nickel-Zirconium Fabriques Par Pulverisation

    NASA Astrophysics Data System (ADS)

    Morel, Robert

    Cette these se situe dans le cadre d'une etude des proprietes electroniques et structurales des alliages metalliques amorphes, en cours depuis quelques annees a l'Universite de Montreal. Ce programme nous a entre autres amene a caracteriser la magnetoresistivite et l'effet Hall d'alliages FeZr, CoZr et NiZr, ce qui a permis de mettre en evidence deux caracteristiques de l'effet Hall: Dans les alliages amorphes ferromagnetiques, la resistivite elevee engendre un effet Hall extraordinaire beaucoup plus important que celui enregistre dans les metaux cristallins. La polarisation des spins entrai ne une asymetrie de la diffusion qui, tant dans les phases cristalline et amorphe, est tenue responsable de cette contribution. L'autre particularite du comportement de Hall de ces systemes est le renversement de signe du coefficient de Hall ordinaire, qui passe du negatif au positif dans les echantillons plus riches en zirconium. Dans les metaux cristallins, un modele d'electrons libres predit un signe negatif a moins que la conduction ne soit dominee par les trous. Or, dans un milieu desordonne les memes concepts sont difficilement applicables et de nouvelles theories ont du etre elaborees pour expliquer ce phenomene. Jusqu'a maintenant, l'etude des alliages amorphes nickel-zirconium s'est faite surtout a partir d'echantillons fabriques par trempe sur roue. Malheureusement cette technique ne permet pas la fabrication d'alliages contenant plus de 70% de nickel, a l'exception du seul compose Ni _{90}Zr_{10 }. Pour pallier a cette lacune et etendre nos connaissance a l'ensemble de la gamme de compositions, nous avons fabrique par pulverisation cathodique des echantillons NiZr amorphes--et quelques alliages cristallins tres riches en nickel--couvrant une bonne partie de la gamme interdite par la technique de trempe sur roue. Dans un premier temps, par comparaison avec les resultats connus nous avons mis en evidence les similitudes et les differences entre les alliages obtenus par

  10. Évaluation des propriétés énergétiques et microphysiques d'une source de convection artificielle à partir d' une étude de combustion organisée de fuel-oil en milieu naturel

    NASA Astrophysics Data System (ADS)

    Dinh, Pham Van; Benech, B.; Diamant, W.

    To evaluate the potential environmental impacts of waste heat released by future dry cooling towers, an oil burning system which emits sensible heat at a rate of the order of 1000 MW into the atmosphere has been built up at the Centre de Recherches Atmosphériques. The project involved development of an oil burner device and experiments to quantify the amounts of heat and other matters released from oil combustion, such as gas and aerosol, that are not present in the case of cooling towers but may interact with heat and cause complications. The burner produces a flame of 3-5 m in height and 0.5-1.5 m in diameter. Fuel is consumed at a rate of 3.5-16.5 ℓ min -1 at a pressure of 30-60 bars to develop a thermal output of 3-11 MW. The thermal power is distributed into three parts: sensible heat (82%), radiative energy (7-13%) and forced convection energy ( ~ 6 %); the two latter energy forms also heat the ambient air and so increase the real sensible heat output which eventually reaches 90 % of the thermal power. When the plume rises to some tens of meters, the combustion gas density is not very different from the air density and the additional water vapor does not exceed 5 % of the ambient water vapor. Smoke aerosol produced at the rate of 2-6gkg -1 of fuel-oil exhibits a maximum concentration of 10 7 particles cm -3 with a mean diameter of 0.5μm. The aerosol consists essentially of hydrophobic carbon (97%), while other elements, that may form hygroscopic or ice nuclei are present only in trace concentrations. The gaseous sulfur content may be higher but the SO 2 oxidation rate is very slow and then the cloud condensation nuclei amounts injected by the plume are neglegible in comparison with the natural nuclei. Thus the thermal impact on the atmosphere of the fuel oil combustion is essentially due to its thermodynamic characteristics, and our 105-burner system (Météotron) should correctly simulate in full scale a dry cooling tower. The smoke particles are quite useful as they make the plume visible and are used as passive tracers of the thermal disturbance.

    contenant de faibles quantites de C, N, O, et Fe pour illustrer comment les abondances d'equilibre des elements supportes reagissent a la redistribution du flux causee par l'addition de ces traces de matiere opaque. Nous traitons ce probleme, en premier lieu, selon une approche basee sur des modeles d'enveloppes et, en second lieu, selon une approche basee sur des modeles d'atmospheres. Nous considerons aussi deux autres ameliorations concernant, premierement, un traitement plus sophistique de la redistribution de la quantite de mouvement d'un ion suite a l'absorption d'un photon, et deuxiemement, l'utilisation d'une meilleure valeur de la largeur du profil de raie associee a l'elargissement par pression. Bien qu'une poignee d'abondances soient disponibles a partir de l'analyse des observations qui ont ete faites jusqu'a maintenant, nous sommes neanmoins capables de conclure, a l'aide de comparaisons detaillees, que la theorie de la levitation radiative a l'equilibre ne reussit pas a expliquer quantitativement les patrons d'abondances des elements lourds observes dans les naines blanches chaudes. Au moins un autre mecanisme doit competionner avec la levitation radiative et le triage gravitationnel dans les atmospheres/enveloppes des naines blanches chaudes. Nous suggerons la possibilite d'un vent stellaire ou encore la possibilite d'accretion.

    2000-08-01

    The Piedra Museo site (Santa Cruz, Argentina), excavated over the past nine years has yielded a rich archaeological record, which contributes to the discussion on the first peopling of the Americas. We present here a new study of the site, based on an analysis of the stratigraphy, spatial distribution of archaeological remains, bone taphonomy, and discussion of new AMS- 14C dates. We conclude that remains of extinct species with cut-marks from the lower levels are contemporaneous of stone tools and cores from the same levels. This demonstrates that humans were present in the southern part of Patagonia around 10 300 and 11 100 years BP and suggests that hunting of large mammals was a part of their subsistence strategies.

    Palaeomagnetic study, carried out in the Moscovian (˜305 Ma) formation in the Edjeleh anticline, shows the existence of three magnetisation components. Two of them are probably Cenozoic and Permian remagnetisations. The third component determined by both well defined ChRMs and remagnetisation circles analysis passes the fold test. Because the folding started before or during the Stephano-Autunian, this third component is the primary magnetisation. Its palaeomagnetic pole (28.3°S, 58.9°E), close to other poles from the Saharan platform obtained from neighbouring periods but without palaeomagnetic tests, confirms the age of these last data.

  1. Réalisation d'un appareillage a lame vibrante pour l'étude des lignes de flux dans les supraconducteurs à haute température critique

    A very sensitive apparatus using the vibrating reed technique in a magnetic field is described. This new technic is an internal friction measurement which has been developed and applied to the study of vortex pinning in high T_c type II superconductors. The vibrating reed is simply used as a sample holder for the superconductor which can be oriented thin films, bulk samples or powders. The salient feature of this experimental set-up is the excitation mode of the reed for which the imposed vibration frequency can be freely chosen in the range 10^{-4}-10 Hz. Furthermore, the measurement sensitivity improves the performances obtained up to now by such similar apparatus as forced torsion pendulums. Damping values corresponding to phase lags between 10^{-5} and 10^{-4} radian can be readily obtained for vibration frequencies in the range 10^{-1} 10 Hz. Some preliminary results show damping peaks which might be due to the so-called fusion of the vortex network obtained with thin films whose thickness is 1000 Å and with textured bulk samples of YBaCuO. Une nouvelle technique basée sur la mesure du frottement intérieur en vibrations forcées est appliquée à l'étude de l'ancrage des vortex dans les oxydes supraconducteurs à haute température critique. Dans cette méthode la lame, excitée électrostatiquement, voit son rôle limité à celui de porte-échantillon sur lequel peuvent être disposés des couches minces, des échantillons massifs ou des poudres. L'originalité de cet appareillage réside dans la conception du mode d'excitation de la lame : la fréquence d'oscillation forcée peut être choisie dans une large gamme allant de 10^{-4} Hz à quelques dizaines de hertz. D'autre part, la sensibilité de la mesure améliore sensiblement les performances obtenues jusqu'à ce jour en vibrations forcées. Des amortissements correspondant à des déphasages compris entre à 10^{-5} et 10^{-4} radian peuvent être facilement mesurés. Les premiers essais r

    Chavez, Milagros

    Cette these presente la trajectoire et les resultats d'une recherche dont l'objectif global est de developper un modele educationnel integrant l'ethique de l'environnement comme dimension transversale de l'education en sciences et en technologies. Face au paradigme positiviste toujours dominant dans l'enseignement des sciences, il a semble utile d'ouvrir un espace de reflexion et de proposer, sous forme d'un modele formel, une orientation pedagogique qui soit plus en resonance avec quelques-unes des preoccupations fondamentales de notre epoque: en particulier celle qui concerne la relation de humain avec son environnement et plus specifiquement, le role de la science dans le faconnement d'une telle relation, par sa contribution a la transformation des conditions de vie, au point de compromettre les equilibres naturels. En fonction de cette problematique generale, les objectifs de la recherche sont les suivants: (1) definir les elements paradigmatiques, theoriques et axiologiques du modele educationnel a construire et (2) definir ses composantes strategiques. De caractere theorico-speculatif, cette recherche a adopte la demarche de l'anasynthese, en la situant dans la perspective critique de la recherche en education. Le cadre theorique de cette these s'est construit autour de quatre concepts pivots: modele educationnel, education en sciences et en technologies, transversalite educative et ethique de l'environnement. Ces concepts ont ete clarifies a partir d'un corpus textuel, puis, sur cette base, des choix theoriques ont ete faits, a partir desquels un prototype du modele a ete elabore. Ce prototype a ensuite ete soumis a une double validation (par des experts et par une mise a l'essai), dans le but d'y apporter des ameliorations et, a partir de la, de construire un modele optimal. Ce dernier comporte deux dimensions: theorico-axiologique et strategique. La premiere s'appuie sur une conception de l'education en sciences et en technologies comme appropriation d

    Le premier colloque Rayons X et Matière (Rx 95) s'est tenu à Strasbourg en 1995. Il était destiné à célébrer le centenaire de la découverte des rayons X par ROENTGEN et a alors réuni plus de cent trente chercheurs et industriels concernés par les rayons X et les matériaux. Parmi eux se trouvaient les Professeurs André GUINIER et Hans NEFF ainsi que Monsieur Michel BRUNEL qui hélas ne sont plus parmi nous à ce jour. La qualité et la convivialité des échanges entre les participants lors de cette première réunion ne pouvaient que nous inciter à la reconduire et nous avons pris rendez vous pour 1997, puis 1999, puis 2001 et enfin pour 2003, soient cinq colloques, un tous les deux ans pendant dix ans. Au cours des années, nous avons essayé d'adapter les thèmes abordés à l'évolution de la recherche et des techniques. Ces thèmes se sont naturellement ajoutés aux thèmes classiques comme la diffraction et la fluorescence. Les nanomatériaux, les microfaisceaux en sont des exemples. A de très rares exceptions les communications présentées étaient de très bon niveau et nous avons toujours eu beaucoup de plaisir à les publier. Ces colloques ont bien fonctionné en raison de la participation des industriels qui, dans leur grande majorité, nous ont accompagnés régulièrement. Ces colloques présentent l'avantage, par rapport à des colloques spécialisés, de couvrir (presque) tout le champ des applications des rayons X et seulement ce domaine. Toutefois il est clair que les données économiques évoluent et que la situation est chaque aimée plus difficile pour tout le monde, chercheurs et industriels. Temps et moyens sont comptés et maintenant chacun doit faire de plus en plus de choix, rentabilité oblige ! Le maintien du colloque Rayons X et Matière passera obligatoirement par une réflexion globale : redéfinition des objectifs, augmentation de l'ouverture européenne, recherche d'autres formes de participation associant mieux les

    Les troubles de l'hémostase sont fréquemment observés en réanimation. L'objectif de cette étude est d'en déterminer l'incidence, les étiologies et la prise en charge pour en diminuer le risque de morbi-mortalité. Etude rétrospective sur une période de huit mois en réanimation chirurgicale du CHUA HUJRA. Les dossiers étudiés étaient ceux contenant tous les premiers bilans d'hémostase lors de l'admission du patient en réanimation, avec un âge supérieur à 15 ans. Etaient exclus les dossiers des post opérés (malade ayant subi une intervention chirurgicale). Les dossiers retenus pour l'étude étaient ceux qui ont présenté une ou plusieurs anomalies au niveau du bilan d'hémostase. Cent cinquante-cinq dossiers ont été colligés dont 20,64% ont présenté un trouble de l'hémostase. Les patients de sexe féminin (53,12%) étaient les plus concernés, avec une population âgée en moyenne de 49±19 ans. Trois patients (9,37%) ont présenté une notion de diathèse hémorragique à l'interrogatoire. Les différents troubles de l'hémostase étaient: une diminution du taux de prothrombine (100%), un taux de céphaline activé allongé (78,12%), un international normalized ratio élevé (43,75%) et des thrombopénies (40,62%). Chez 3,12% de ces cas, des accidents hémorragiques ont survenu. La plupart de ces troubles de l'hémostase étaient présents au décours d'hémorragies digestives (46,87%) dont la prise en charge était constituée par l'administration de vitamine K1 (68,75%) et de transfusion de plasma frais congelé (65,62%). D'autres pathologies ont été également incriminées. Une incidence de 15,62% de mortalité a été retrouvée. L'existence des troubles de l'hémostase en réanimation constitue un facteur pronostique imposant un dépistage et une prise en charge précoces et adéquats pour pouvoir en réduire le taux de mortalité.

    La Madeleine, Carole

    Ce memoire est presente a la Faculte de medecine et des sciences de la sante de l'Universite de Sherbrooke en vue de l'obtention du grade de maitre es sciences (M.Sc.) en radiobiologie (2009). Un jury a revise les informations contenues dans ce memoire. Il etait compose de professeurs de la Faculte de medecine et des sciences de la sante soit : Darel Hunting PhD, directeur de recherche (departement de medecine nucleaire et radiobiologie), Leon Sanche PhD, directeur de recherche (departement de medecine nucleaire et radiobiologie), Richard Wagner PhD, membre du programme (departement de medecine nucleaire et radiobiologie) et Guylain Boissonneault PhD, membre exterieur au programme (departement de biochimie). Le 5-bromodeoxyuridine (BrdU), un analogue halogene de la thymidine reconnu depuis les annees 60 comme etant un excellent radiosensibilisateur. L'hypothese la plus repandue au sujet de l'effet radio sensibilisant du BrdU est qu'il augmente le nombre de cassures simple et double brin lorsqu'il est incorpore dans l'ADN de la cellule et expose aux radiations ionisantes. Toutefois, de nouvelles recherches semblent remettre en question les observations precedentes. Ces dernieres etudes ont confirme que le BrdU est un bon radiosensibilisateur, car il augmente les dommages radio-induits dans l'ADN. Mais, c'est en etant incorpore dans une region simple brin que le BrdU radiosensibilise l'ADN. Ces recherches ont egalement revele pour la premiere fois un nouveau type de dommages produits lors de l'irradiation de l'ADN contenant du BrdU : les dimeres interbrins. Le but de ces travaux de recherche est de determiner si la presence de bromodeoxyuridine dans l'ADN augmente l'induction de bris simple et / ou double brin chez les cellules irradiees en utilisant de nouvelles techniques plus sensibles et specifiques que celles utilisees auparavant. Pour ce faire, les essais cometes et la detection des foci H2AX phosphorylee pourraient permettre d'etablir les effets engendres par

    Albert, Loic

    Cette thèse comporte un volet d'instrumentation astronomique, le spectrographe infrarouge SIMON, et un volet de recherche, la recherche de naines brunes autour d'étoiles (lu voisinage solaire. Le premier volet fait état de la construction du Spectrographe infrarouge de Montréal (SIMON), un instrument polyvalent fonctionnant dans le proche infrarouge (0.8-2.5 [mu]m) conçu pour être utilisé à l'Observatoire du mont Mégantic (OMM) et au télescope Canada-France-Hawaii (TCFH). SIMON regroupe plusieurs fonctionnalités: l'irnagerie, la spectroscopie, la spectroscopie rnulti-objets et la polarimétrie. Comme imageur, il offre un champ de vue (le 7.7'x 7.7' à l'OMM et 3.3' x 3.3' au TCFH et possède huit filtres dont un filtre I . SIMON compte trois disperseurs pour la spectroscopie: (1) un prisme d'Amici R max [approximate]50, 0.8-2.5 [mu]m); (2) un grism de silice (R max [approximate]750, 1.17-2.34 [mu]m); et un grism de KRS-5 (R max [approximate]3000, bande J,H ou K S ). Le mode spectroscopique multi-objets utilise des masques cryogéniques placés dans un second cryostat et, couplé au prisme d'Amici, permet l'obtention d'une centaine de spectres simultanément. Le mode polarimétrique permet l'observation de quatre vecteurs de polarisation simultanément. Cette première moitié de thèse étaye les objectifs scientifiques, détaille la conception optique (collimatrice et caméra) et mécanique (un cryostat principal contenant trois cotres à filtres et le détecteur, un cryostat amovible contenant nue roue à masques), décrit l'électronique et le système d'acquisition, et enfin présente les performances dans les différents modes. Le second volet de cette thèse est un relevé grand champ à la recherche de naines brunes de type T autour de 66 étoiles du voisinage solaire. Il a été effectué en utilisant des caméras infrarouges (dont SIMON) et des CCD sur divers télescopes. Le diagramme I--J vs. J--H utilisé est. efficace pour isoler des naines T

  7. Carbon nano structures: Production and characterization

    NASA Astrophysics Data System (ADS)

    Beig Agha, Rosa

    L'objectif de ce memoire est de preparer et de caracteriser des nanostructures de carbone (CNS -- Carbon Nanostructures, en licence a l'Institut de recherche sur l'hydrogene, Quebec, Canada), un carbone avec un plus grand degre de graphitisation et une meilleure porosite. Le Chapitre 1 est une description generale des PEMFCs (PEMFC -- Polymer Electrolyte Membrane Fuel Cell) et plus particulierement des CNS comme support de catalyseurs, leur synthese et purification. Le Chapitre 2 decrit plus en details la methode de synthese et la purification des CNS, la theorie de formation des nanostructures et les differentes techniques de caracterisation que nous avons utilises telles que la diffraction aux rayons-X (XRD -- X-ray diffraction), la microscopie electronique a transmission (TEM -- transmission electron microscope ), la spectroscopie Raman, les isothermes d'adsorption d'azote a 77 K (analyse BET, t-plot, DFT), l'intrusion au mercure, et l'analyse thermogravimetrique (TGA -- thermogravimetric analysis). Le Chapitre 3 presente les resultats obtenus a chaque etape de la synthese des CNS et avec des echantillons produits a l'aide d'un broyeur de type SPEXRTM (SPEX/CertiPrep 8000D) et d'un broyeur de type planetaire (Fritsch Pulverisette 5). La difference essentielle entre ces deux types de broyeur est la facon avec laquelle les materiaux sont broyes. Le broyeur de type SPEX secoue le creuset contenant les materiaux et des billes d'acier selon 3 axes produisant ainsi des impacts de tres grande energie. Le broyeur planetaire quant a lui fait tourner et deplace le creuset contenant les materiaux et des billes d'acier selon 2 axes (plan). Les materiaux sont donc broyes differemment et l'objectif est de voir si les CNS produits ont les memes structures et proprietes. Lors de nos travaux nous avons ete confrontes a un probleme majeur. Nous n'arrivions pas a reproduire les CNS dont la methode de synthese a originellement ete developpee dans les laboratoires de l'Institut de

  8. Stratigraphic and geochemical controls on naturally occurring arsenic in groundwater, eastern Wisconsin, USA

    NASA Astrophysics Data System (ADS)

    Schreiber, M. E.; Simo, J. A.; Freiberg, P. G.

    pyrite et dans les sulfates dissous et la corrélation entre les concentrations en sulfates, en fer et en arsenic dissous laissent penser que l'oxydation des sulfures est le processus dominant contrôlant la libération de l'arsenic dans les eaux souterraines. Cependant, les oxy-hydroxydes contenant de l'arsenic sont susceptibles d'être une autre source d'arsenic si des conditions réductrices apparaissent ou s'ils sont transportés dans l'aquifère sous forme de colloïdes. L'analyse des données provenant de puits montre que l'intersection entre le SCH et les niveaux statiques des puits domestiques est fortement corrélée à de fortes concentrations en arsenic dans les eaux souterraines. Des données de terrain et de laboratoire conduisent à penser que la contamination en arsenic la plus forte est causée par l'interaction localisée aux forages entre l'air, l'eau et les sulfures. Bien que la contamination en arsenic soit causée par l'oxydation de sulfures présents naturellement, elle est influencée par les fluctuations du niveau piézométrique causées par les pompages du captage municipal ou par les variations climatiques, ce qui peut conduire au déplacement des zones géographiques où se produisent les contaminations. Resumen Se han medido concentraciones de arsénico muy altas (de hasta 12000μg/L) en las aguas subterráneas de un acuífero confinado, en areniscas, localizado en la parte oriental de Wisconsin (EEUU). La fuente principal de arsénico es un horizonte de cementación secundaria (SCH) con un alto contenido en sulfuros, y con una gran variabilidad en espesor, morfología y concentraciones de As. El arsénico aparece en piritas y marcasitas, además de en oxihidróxidos de hierro, pero no como una fase independiente de arsenopiritas. El hecho que la marca isotópica de piritas y sulfatos disueltos sea muy similar, y que exista una gran correlación entre las concentraciones de sulfato disuelto, hierro y arsénico sugiere que la oxidación de

    -africains en optométrie sur la possibilité de travailler dans les zones rurales après avoir terminé leur formation et identifier les facteurs pouvant influencer leur décision. Méthode C’est une étude quantitative transversale utilisant un instrument de sondage contenant des questions semi-structurées fermée et ouvertes. Résultats Quatre cent trente-huit étudiants ont répondu au questionnaire (un taux de réponse de 85.4%). En général, un grand nombre de répondants ne voulaient pas ouvrir leur premier (66%) ou deuxième cabinet (64.6%) dans les zones rurales. Cependant, la plupart des répondants originaires de la campagne ont répondu qu’ils ouvriraient leur premier cabinet (77.2%) ou leur second (79.4%) dans les zones rurales. Les raisons principales citées par les répondants pour ne pas vouloir travailler dans les zones rurales étaient des préoccupations financières (81.2%), la sécurité personnelle (80.1%) et les mauvaises conditions de vie (75.3%), avec un plus grand nombre (p < 0.05) de la part des répondants urbains pour les deux derniers problèmes. Conclusion Beaucoup d’étudiants ne voulaient pas ouvrir de cabinet dans les zones rurales, mais étaient prêts à travailler pour le gouvernement ou une organisation non-gouvernementale après l’obtention de leur diplôme. Il faudra s’occuper des incitations financières, de la sécurité et des conditions de vie dans les zones rurales. Les résultats de cette étude ont des implications pour le futur de la disponibilité et de l’accessibilité des services de soins oculaires pour ceux qui vivent dans les zones rurales et les régions reculées du pays.

    Intermetallic materials such as Ni{sub 2}Ti, Cr{sub 2}Ti are among advanced technology materials that have outstanding mechanical and physical properties for high temperature applications. Especially creep resistance, low density and high hardness properties stand out in such intermetallics. The microstructure, mechanical properties of (%50Ni-%48Cr-%2Ti)-%10Naturel Fibres and (%64Ni-%32Cr-%4Ti)-%10Naturel Fibres powders were investigated using specimens produced by tube furnace sintering at 1000-1200-1400°C temperature. A composite consisting of ternary additions, a metallic phase, Ti,Cr and Ni have been prepared under Ar shroud and then tube furnace sintered. XRD, SEM (Scanning Electron Microscope), were investigated to characterize the properties of the specimens. Experimental results carried out for composition (%64Ni-%32Cr-%4Ti)-%10Naturel at 1400°C suggest that the best properties as 112.09HV and 5,422g/cm{sup 3} density were obtained at 1400°C.

    Le LMARC a été créé par Raymond Chaléat dans les locaux de l'École Nationale d'Horlogerie (a présent Lycée Technique Jules Haag).L'équipe de recherche était alors constituée de 2 enseignants-chercheurs (Raymond Chaléat et Gérard Lallement) et d'un technicien (Bernard Prêtre). Les travaux de recherche se situaient naturellement dans le domaine de la chronométrie et en particulier dans la mécanique non linéaire analytique inhérente à la montre en fonctionnement. En effet, Raymond Chaléat fut l'élève, puis le collaborateur du Professeur Jules Haag, mathématicien et mécanicien, lui-même élève de Poincarré.Le LMARC a étendu ses activités avec l'arrivée de Claude Oudet, puis de Claude Oytana à la rhéologie des matériaux solides qui est devenue plus tard l'Équipe Propriétés Mécaniques des Matériaux. En parallèle, G. Lallement a créé une équipe Vibrations devenue à ce jour Dynamique des Structures. À ce jour, le Laboratoire compte plus de 110 personnes dont 40 doctorants.Il a depuis diversifié ses activités avec 3 nouvelles équipes tournées vers la Modélisation et la Mise en Forme des Matériaux, les Micromachines et la Biomécanique et les Mécanismes. Il a su également prendre toute sa place au sein de l'Institut des Microtechniques de Franche-Comté en contribuant à plusieurs thèmes.Notre Laboratoire a été l'un des premiers laboratoires associé au CNRS (4ème) et a toujours été rattaché à l'Université de Franche-Comté (Présidence par C. Oytana de 1996 a 2001) par l'entremise de I'UFR Sciences et Techniques. Il a toujours maintenu des liens forts avec I'ENSMM (École Nationale Supérieure de Mécanique et des Microtechniques) d'une part par ses enseignants-chercheurs et d'autre part deux de ses directeurs, Raymond Chaléat et actuellement Jean-Claude Gelin.En plus de ses relations constantes avec l'industrie régionale, le LMARC a développé des actions contractuelles avec de grands groupes tels que EDF

  10. Etude des phenomenes chimiques au contact entre le bloc cathodique et la barre collectrice d'une cellule d'electrolyse d'aluminium

    NASA Astrophysics Data System (ADS)

    Lebeuf, Martin

    La production d'aluminium est une industrie importante au Québec. Les propriétés de ce métal le vouent à de multiples usages présents et futurs dans le cadre d'une économie moderne durable. Toutefois, le procédé Hall-Héroult est très énergivore et des progrès demeurent donc nécessaires pour en diminuer les coûts financiers et environnementaux. Parmi les améliorations envisageables de la cellule d'électrolyse se trouve le contact entre la cathode et la barre collectrice, qui doit offrir une faible résistivité au passage du courant électrique. En cours d'opération de la cellule, ce contact a tendance à se dégrader, générant des pertes énergétiques significatives. Les causes de cette dégradation, pouvant provenir de phénomènes chimiques, thermiques, mécaniques et/ou électriques, demeurent mal comprises. Le but du présent projet était donc d'étudier les phénomènes chimiques se produisant au contact bloc-barre de la cellule d'électrolyse Hall-Héroult. En premier lieu, un aspect crucial à considérer est la pénétration du bain électrolytique dans la cathode, car des composés de bain atteignent éventuellement la barre collectrice et peuvent y réagir. A cet effet, une méthode novatrice a été développée afin d'étudier les cathodes et la pénétration du bain dans celles-ci à l'aide de la microtomographie à rayons X. Cette méthode rapide et efficace s'est avérée fort utile dans le projet et a un potentiel important pour l'étude future des cathodes et des phénomènes qui s'y produisent. Ensuite, une cellule d'électrolyse rectangulaire à petite échelle a été développée. Plusieurs phénomènes observés 'en industrie sur des autopsies de cellules post-opération et rapportés dans la littérature ont été reproduis avec succès à l'aide de cette cellule expérimentale. Puis, des tests sans électrolyse, ciblant l'effet du bain électrolytique sur l'acier, ont aussi été conçus et complétés afin de s

  11. Etude theorique et experimentale des evaporateurs de dioxyde de carbone operant dans des conditions de givrage

    NASA Astrophysics Data System (ADS)

    Bendaoud, Adlane Larbi

    Les evaporateurs de refrigeration sont surtout du type tube a ailettes, appeles serpentins, et fonctionnent dans l'une des conditions suivantes: seche, humide ou avec formation de givre. Il a ete demontre que la formation du givre sur la paroi exterieure de l'echangeur engendre une surconsommation energetique a cause des operations de degivrage puisque 15 a 20% seulement de la chaleur produite sert au degivrage tandis que le reste est dissipee dans l'environnement [1]. Avec l'avenement des nouveaux refrigerants, moins nocifs envers l'environnement, l'industrie du froid se trouve penalisee du fait que peu ou pas de composantes mecaniques (compresseur, pompe, echangeur...etc.) adaptees sont disponibles [3]. Il s'agit pour la communaute des frigoristes de combler ce retard technologique en redeveloppant ces composantes mecaniques afin qu'elles soient adaptees aux nouveaux refrigerants. Dans cette optique, et afin de mieux comprendre le comportement thermique des evaporateurs au CO2 fonctionnant dans des conditions seches, qu'un groupe de chercheurs du CanmetENERGIE avaient lance, en 2000, un programme de R & D. Dans le cadre de programme un outil de simulation des evaporateurs au CO2 a ete developpe et un banc d'essai contenant une boucle secondaire de refrigeration utilisant le CO2 comme refrigerant a ete construit. Comme continuite de ce travail de recherche, en 2006 ce meme groupe de recherche a lance un nouveau projet qui consiste a faire une etude theorique et experimentale des evaporateurs au CO2 operants dans des conditions de givrage. Et, c'est exactement dans le cadre de ce projet que se positionne ce travail de these. Ce travail de recherche a ete entrepris pour mieux comprendre le comportement thermique et hydrodynamique des serpentins fonctionnant dans des conditions de givrage, l'effet des circuits de refrigerant ainsi que celui des parametres geometriques et d'operation. Pour cela, un travail theorique supporte par une etude experimentale a ete effectue

  12. Environnement des Systèmes Binaires Jeunes

    NASA Astrophysics Data System (ADS)

    Duchene, Gaspard

    2000-07-01

    La fréquence élevée des systèmes binaires, tant parmi les étoiles de la séquence principale que dans les régions de formation stellaire, a été largement mise en évidence au cours des dix dernières années. Cette constatation soulève naturellement la question de la nature du processus responsable de la formation préférentielle de ces systèmes multiples. Par ailleurs, les phénomènes d'interaction entre un compagnon et l'environnement complexe d'une étoile T Tauri sont encore trèsmal compris. C'est dans ce cadre que se place le travail conduit durant cette thèse, dont les principaux objectifs sont: i) la détermination de la fraction de binaires dans différentes populations pré-séquence principale, ii) l'étude quantitative du phénomène d'accrétion dans les systèmes binaires T Tauri, et iii) l'observation directe et la modélisation de disques circumstellaires et circumbinaires. Dans le cadre d'une recherche de binaires visuelles à l'aide du système d'optique adaptative du Télescope Canada-France-Hawaii, j'ai pris part à l'observation de plusieurs centaines d'objets situés dans différents amas stellaires jeunes. Je détaille ici l'analyse et les résultats concernant deux amas âgés de moins de deux millions d'années. Lorsqu'on considère l'ensemble des populations étudiées jusqu'à présent, on constate que la proportion de binaires visuelles parmi les étoiles de type solaire est la même dans les amas stellaires que sur la séquence principale. De plus, cette propriété ne dépend pas de l'âge de l'amas, ce qui implique que la fraction de binaires n'évolue pas après le premier million d'années dans ces amas. A l'opposé, les zones de formation peu denses, qui sont toutes très jeunes, possèdent une proportion de binaires sensiblement plus élevée. Les modèles les plus à même de reproduire ces observations sont ceux selon lesquels la fraction de binaires qui résulte de l'effondrement gravitationnel est proche de 100

    Cette recherche vise a la mise en oeuvre optique de reseaux neuronaux. Deux architectures differentes sont proposees. La premiere est la memoire associative permettant d'associer a un objet quelconque une sortie arbitraire tout en preservant l'information sur sa position. La seconde architecture, le classificateur neuronal pour le controle robotique, permet l'identification d'une entree et son classement selon differentes categories. La sortie est compatible avec les systemes numeriques standard. Pour realiser ces architectures, une approche modulaire est privilegiee. Le correlateur constitue le module de base des realisations. Differents modules sont de plus introduits pour realiser convenablement les operations neuronales. Le premier de ces modules est le seuil optoelectronique permettant de realiser une fonction non lineaire, element essentiel des reseaux neuronaux. Le second module a etre introduit est l'encodeur optonumerique, utile au classement des objets. Le probleme de l'enregistrement de la memoire est aborde a l'aide du codage iteratif global.

    Sulfenate anions are known to act as highly reactive species in the organic arena. Now they premiere as organocatalysts. Proof of concept is offered by the sulfoxide/sulfenate-catalyzed (1-10 mol%) coupling of benzyl halides in the presence of base to generate trans-stilbenes in good to excellent yields (up to 99%). Mechanistic studies support the intermediacy of sulfenate anions, and the deprotonated sulfoxide was determined to be the resting state of the catalyst. PMID:25111259

    Translucent tissue defect (TTD) is an undesirable postharvest disorder of potato tubers characterized by the development of random pockets of semi-transparent tissue containing high concentrations of reducing sugars. Translucent areas turn dark during frying due to the Maillard reaction. The newly released cultivar, Premier Russet, is highly resistant to low temperature sweetening, but susceptible to TTD. Symptoms appeared as early as 170 days after harvest and worsened with time in storage (4-9 °C, 95 % RH). In addition to higher concentrations of glucose, fructose and sucrose, TTD resulted in lower dry matter, higher specific activities of starch phosphorylase and glc-6-phosphate dehydrogenase, higher protease activity, loss of protein, and increased concentrations of free amino acids (esp. asparagine and glutamine). The mechanism of TTD is unknown; however, the disorder has similarities with the irreversible senescent sweetening that occurs in tubers during long-term storage, where much of the decline in quality is a consequence of progressive increases in oxidative stress with advancing age. The respiration rate of non-TTD 'Premier Russet' tubers was inherently higher (ca. 40 %) than that of 'Russet Burbank' tubers (a non-TTD cultivar). Moreover, translucent tissue from 'Premier Russet' tubers had a 1.9-fold higher respiration rate than the average of non-translucent tissue and tissue from non-TTD tubers. Peroxidation of membrane lipids during TTD development resulted in increased levels of malondialdehyde and likely contributed to a measurable increase in membrane permeability. Superoxide dismutase and catalase activities and the ratio of oxidized to total glutathione were substantially higher in translucent tissue. TTD tubers also contained twofold less ascorbate than non-TTD tubers. TTD appears to be a consequence of oxidative stress associated with accelerated aging of 'Premier Russet' tubers. PMID:24037414

    MARSCHALS (Millimetre-wave Airborne Receivers for Spectroscopic CHaracterisation in Atmospheric Limb Sounding) is a limb viewing instrument working in the millimetre and sub-millimetre spectral regions (from 294 to 349 GHz). The scientific rationale of MARSCHALS is the study of the Upper Troposphere and Lower Stratosphere region. In March 2010 MARSCHALS was deployed on-board the M-55 Geophysica stratospheric aircraft during the PREMIER(PRocess Exploration through Measurements of Infrared and millimetre-wave Emitted Radiation)-Ex field campaign. From the campaign base at Kiruna, Sweden, a research flight to investigate the Arctic atmosphere was conducted. For the first time the instrument fully exploited the three spectral bands. In this paper, we present results of the analysis of MARSCHALS measurements acquired during the PREMIER-Ex flight as processed by the Millimetre-wave Atmospheric Retrieval Code. For the second time after the SCOUT-O3 flight in 2005, MARSCHALS measured vertical distributions of temperature, water vapour, ozone and nitric acid over an altitude range of 4 to 24 km. In addition, vertical profiles of carbon monoxide and nitrous oxide were obtained for the first time. The measurements were performed in clear sky conditions and in presence of low and high altitude clouds (that were able to obscure measurements in the middle infrared spectroscopic region) and some information about thick clouds were extracted from the data. The capabilities to derive information on upper tropospheric and lower stratospheric vertical profiles of temperature and minor constituents from millimetre-wave limb sounding observations in the northern polar region are presented and discussed for each of the individual targets. The results of MARSCHALS data analysis contributed to demonstrate the scientific relevance and technical feasibility of millimetre-wave limb-sounding of the UTLS proposed for the ESA Earth Explorer 7 candidate Core Mission PREMIER.

    Ballet dancers are competitive athletes who undergo extreme physical and mental stress and work according to an irregular schedule, with long days of training, rehearsal, and performance. Their most significant potential risks entail physical injury and altered sleep. The elaborate training requirements for ballet dancers do not allow regular chronobiological patterns or a normal sleep-wake rhythm. Our aim was to investigate the sleep-wake rhythm and sleep quality during rehearsal phases prior to a ballet premiere. We used wrist actigraphy and sleep diaries for a period of 67 days before the ballet premiere performance to study 24 classical ballet dancers. We likewise applied the Epworth Sleepiness Score (ESS), Pittsburgh Sleep Quality Index (PSQI), SF-12 Quality of life Assessment, and d2 Test of Attention to assess quality of sleep, aspects of cognitive performance, and health status. We found significant reduction in sleep duration, from 418+/-43 min to 391+/-42 min, and sleep efficiency, from 81+/-4% to 79+/-5%, over the 67-day course of the rehearsal. We also found a decline in time in bed and an increase in wakefulness after sleep onset. Sleep onset latency did not change. However, the changes in sleep as documented by actigraphy were not reflected by the subjective data of the sleep diaries and sleep scores. As a result of the facts that total sleep efficiency and sleep duration values were already lower than usual for the dancers' age group at the beginning of the study and that mental acuity, concentration, and speed were likewise impaired, we observed exacerbated health deterioration in terms of sleep deprivation in ballet dancers during preparation for a premier. We conclude that individual activity-rest schedules, including daytime naps, may be helpful, especially during the stressful training and rehearsal experienced prior to ballet premieres.

Dead-burned magnesia was produced by Martin Marietta Magnesia Specialties from well brines in Michigan. Caustic-calcined magnesia was recovered from sea-water by Premier Chemicals in Florida; from well brines in Michigan by Martin Marietta and Rohm and Haas; and from magnesite in Nevada by Premier Chemicals. Intrepid Potash-Wendover and Great Salt Lake Minerals recovered magnesium chloride brines from the Great Salt Lake in Utah. Magnesium hydroxide was produced from brucite by Applied Chemical Magnesias in Texas, from seawater by SPI Pharma in Delaware and Premier Chemicals in Florida, and by Martin Marietta and Rohm and Haas from their operations mentioned above. About 59 percent of the magnesium compounds consumed in the United States was used for refractories that are used mainly to line steelmaking furnaces. The remaining 41 percent was consumed in agricultural, chemical, construction, environmental and industrial applications.

    From February 4 to 11, 1945, President Franklin D. Roosevelt of the United States, Soviet Union Premier Joseph Stalin, and British Prime Minister Winston Churchill met near Yalta in Crimea to discuss how post-World War II (WWII) Europe should be organized. Within 2 decades of this conference, all 3 men had died. President Roosevelt died 2 months after the Yalta Conference due to a hemorrhagic stroke. Premier Stalin died 8 years later, also due to a hemorrhagic stroke. Finally, Prime Minister Churchill died 20 years after the conference because of complications due to stroke. At the time of Yalta, these 3 men were the leaders of the most powerful countries in the world. The subsequent deterioration of their health and eventual death had varying degrees of historical significance. Churchill's illness forced him to resign as British prime minister, and the events that unfolded immediately after his resignation included Britain's mismanagement of the Egyptian Suez Crisis and also a period of mistrust with the United States. Furthermore, Roosevelt was still president and Stalin was still premier at their times of passing, so their deaths carried huge political ramifications not only for their respective countries but also for international relations. The early death of Roosevelt, in particular, may have exacerbated post-WWII miscommunication between America and the Soviet Union-miscommunication that may have helped precipitate the Cold War.

    1998-05-01

    In this paper, flatband potential measurements are used to study the Fermi Level Pinning (FLP) at the n or p-GaAs/aqueous and non aqueous electrolyte interface. The semiconductor is put in contact with an aqueous solution containing the 18-tungsto-diphosphate P2W{18}O{62}6- heteropolyanion as a redox system and with two non aqueous solutions: acetonitrile (ACN) and propylene carbonate (CP) in the presence of various redox couples. Our results are firstly analyzed according to the classical model proposed for solid-state semiconductor/metal junctions. A more specific model accounting for the coupling between corrosion and redox reactions at the semiconductor/electrolyte interface is developped. The semiconductor surface equilibrates mainly with the redox species in ACN solutions (total FLP), and only weakly in H2O or CP solutions, because of the pre-eminence of the semiconductor/solvent interactions. Dans cet article, l'ancrage du niveau de Fermi dans les jonctions semiconducteur/électrolyte est étudié à partir de la détermination du potentiel de bandes plates. Le semiconducteur est l'arséniure de gallium (n et p) qui est mis en contact respectivement avec un milieu aqueux contenant un hétéropolyanion comme système oxydo-réducteur, le 18-tungsto-diphosphate P2W{18}O{62}6-, et avec deux milieux non aqueux : l'acétonitrile (ACN) et le carbonate de propylène (CP) contenant divers couples redox. Les résultats sont d'abord analysés suivant le modèle proposé classiquement pour les jonctions semiconducteur/métal, puis à l'aide d'un modèle développé spécifiquement dans le cas de l'interface semiconducteur/électrolyte, prenant en compte le couplage entre réaction de corrosion et réaction redox. En milieu ACN, la surface du semiconducteur s'équilibre principalement avec le système redox (FLP total), et seulement partiellement en milieu H2O ou CP, au profit des interactions avec le milieu électrolytique.

  4. Argon isotopic studies of minerals in kimberlites, mantle xenoliths and diamonds, from selected southern African localities

    1989-01-01

    The occurrence, composition, behavior and origin of excess argon components, in mantle phases hosted by southern African kimberlites, is evaluated using furnace step-heating and laser-probe analytical techniques. Laser-probe {sup 40}Ar/{sup 39}Ar analyses of phlogopite from the swartruggens kimberlite dyke (145 Ma), and Premier diatreme ({approximately}1200 Ma) lherzolite xenoliths, yielded apparent ages decreasing from high ages at grain centres to values approaching the age of kimberlite intrusion, along grain margins. The old apparent ages are attributed excess radiogenic argon, with high {sup 40}Ar/{sup 39}Ar ratios (> 15,000), incorporated prior to kimberlite intrusion under conditions of locally high argon partial pressure. The preservation of the excess argon components is dependent on the timing of melt devolatilization, temperature, cooling rate and the characteristic radius for argon diffusion. Swartruggens phlogopite grains also display chlorine zonations, measured by a neutron activation technique and the laser probe. Fluorine contents, determined by electron microprobe were uniform. Halogen analyses of Premier xenolith phlogopite revealed minor variations. {sup 40}Ar/{sup 39}Ar laser-probe analyses of eclogitic suite clinopyroxene inclusions in diamonds from the Premier kimberlite yielded an age of 1198 {plus minus} 6 Ma, indistinguishable from the inferred time of intrusion of the host kimberlite ({approximately}1200 Ma). This implies diamond formation synchronous with, or no more than {approximately}20 Ma before kimberlite generation. The associated initial {sup 40}Ar/{sup 39}Ar ratio of 334 {plus minus} 50 is similar to the present day atmospheric composition. It is suggested that late-stage equilibration with {sup 36}Ar-rich fluids, derived either from primordial mantle, or from subducted atmospheric argon, is the most likely explanation for this low {sup 40}Ar/{sup 39}Ar value.

    Context: Injuries are a major adverse event in a soccer player's career. Reducing injury incidence requires a thorough knowledge of the epidemiology of soccer injuries. Objective: To investigate the incidence and characteristics of injuries in the Dutch premier soccer league. Design: Cohort study. Setting: The Dutch premier soccer league. Patients or Other Participants: During the 2009–2010 soccer season, a total of 217 professional soccer players from 8 teams were prospectively followed. Main Outcome Measure(s): The medical staff recorded time-loss injuries, including information on injuries (ie, type, body part, duration) and exposure data for training sessions and matches. Results: A total of 286 injuries were recorded, affecting 62.7% of the players. The overall injury incidence was 6.2 injuries per 1000 player-hours, 2.8 in training sessions and 32.8 in matches. Most of the recorded injuries were acute (68.5%). Eight percent of the injuries were classified as recurrent. Injuries were most likely to be located in the lower extremities (82.9%). Injury time loss ranged from 1 to 752 days, with a median of 8 days. Knee injuries had the greatest consequences in terms of days of absence from soccer play (on average, 45 days). The most common diagnosis was muscle/tendon injury of the lower extremities (32.9%). Conclusions: Injury risk in the Dutch premier soccer league is high, especially during matches. Preventive measures should focus on the most common diagnoses, namely, muscle/tendon injuries of the lower extremities. PMID:25531144

    Isotope analyses of Os, Sr, Nd, and Pb elements were caried out on twelve peridotite xenoliths from the Jagersfontein, Letseng-la-terae, Thaba Patsoa, Mothae, and Premier kimberlites of southern Africa, to investigate the timing and the nature of melt extraction from the continental lithosphere and its relation to the continent formation and stabilization. The distinct Os and Pb isotopic characteristics found in these samples suggested that both the low- and the high-temperature peridotites reside in an ancient stable lithospheric 'keel' to the craton that has been isolated from chemical exchange with the sublithospheric mantle for time periods in excess of 2 Ga.

    The electronic structures of monolayer silicenes (4 × 4 and ) grown on Ag (111) surface are studied by scanning tunneling spectroscopy (STS) and density functional theory (DFT) calculations. While both phases have similar electronic structures around the Fermi level, significant differences are observed in the higher energy unoccupied states. The DFT calculations show that the contributions of Si 3pz orbitals to the unoccupied states are different because of their different buckled configurations.

    1997-08-01

    General circulation models are becoming the premier theoretical tools for studying the complex structure of the global climate. GEONET was envisioned as exercising the resources developed for the nuclear weapons program to address environmental problems. The similarity of circulation models to weapons codes made them an attractive field for them to develop expertise. The author hoped to become an active player in mainline climate research through computer simulation. This is the final report of a three-year, Laboratory-Directed Research and Development (LDRD) project at the Los Alamos National Laboratory (LANL). The intention of this research was to establish the Laboratory in mainstream climate research in conjunction with the GEONET project.

    Cost has long been a deterrent when trying to stream live events to large audiences. While streaming providers like UStream have free options, they include advertising and typically limit broadcasts to originating from a single location. In the autumn of 2011, Google premiered a new, free, video streaming tool -- Hangouts on Air -- as part of their Google+ social network. This platform allows up to ten different computers to stream live content to an unlimited audience, and automatically archives that content to YouTube. In this article we discuss best practices for using this technology to stream events over the internet.

    The Shannon Estuary on the west coast of Ireland is one of Europe's premier deepwater berths catering for ships up to 200,000 deadweight tonnage. It is also Ireland's only designated candidate special area of conservation for bottlenose dolphins under the EU Habitats Directive. Long-term static acoustic monitoring was carried out at a number of intensive shipping sites. In 2012, noise monitoring took place over a 6-month period (at 1 site) as part of Ireland's requirements under the Marine Strategy Framework Directive (MSFD). This is the first assessment of the potential effect of vessel traffic on the behavior of this discrete dolphin population. PMID:26611032

    RNA sequencing has emerged as the premier approach to study bacterial transcriptomes. While the earliest published studies analyzed the data qualitatively, the data are readily digitized and lend themselves to quantitative analysis. High-resolution RNA sequence (RNA-seq) data allows transcriptional features (promoters, terminators, operons, etc.) to be pinpointed on any bacterial transcriptome. Once the transcriptome is mapped, the activity of transcriptional features can be quantified. Here we highlight how quantitative transcriptome analysis can reveal biological insights and briefly discuss some of the challenges to be faced by the field of bacterial transcriptomics in the near future.

    RELAP5-3D is used worldwide for analyzing nuclear reactors under both operational transients and postulated accident conditions. Development of the RELAP code series began in 1975 and since that time the code has been continuously improved, enhanced, verified and validated [1]. Since RELAP5-3D will continue to be the premier thermal hydraulics tool well into the future, it is necessary to modernize the code to accommodate the incorporation of additional capabilities to support the development of the next generation of nuclear reactors [2]. This paper discusses the reengineering of RELAP5-3D into structured code.

    This article critically utilizes the work of Manuel Castells to discuss the issue of parallel imported broadcasts (specifically including live-streams) in football. This is of crucial importance to sport because the English Premier League is premised upon the sale of television rights broadcasts to domestic and overseas markets, and yet cheaper alternative broadcasts endanger the price of such rights. Evidence is drawn from qualitative fieldwork and library/Internet sources to explore the practices of supporters and the politics involved in the generation of alternative broadcasts. This enables us to clarify the core sociological themes of 'milieu of innovation' and 'locale' within today's digitally networked global society. PMID:22670651

    ELTECH System Corporation has developed and patented a Mesh-on-Lead™ (MOL™) (Mesh-on-Lead and MOL are trademarks of ELTECH Systems Corporation) anode for primary copper electrowinning operations. Over the past five years, ELTECH has demonstrated the MOL concept with full-scale anodes at several premier commercial tankhouses. During these demonstrations MOL anodes exhibited numerous performance advantages relative to standard Pb-Ca-Sn anodes, including reduced power consumption due to lower oxygen evolution over-potential, improved cathode quality, minimized lead sludge generation, eliminated cobalt addition as a result of stabilized lead substrate, and improved current efficiency due to reduced short circuiting.

    The Chandra X-Ray Observatory is entering its third year of operation. The Observatory, the premiere x-ray telescope for high-resolution imaging, has exceeded all expectations. The sub-arc second angular resolution together with other instrumental capabilities has allowed for new insights into the understanding of compact x-ray emitting objects including neutron stars and pulsars. We briefly review the Chandra Program and the first two years of observation with emphasis on these interesting objects. We detail the results of our observations of the pulsar in the Crab Nebula including the first continuum spectrum that is virtually uncontaminated by any dust-scattered radiation.

  13. The lightbulb project: New music for new percussion instruments

    NASA Astrophysics Data System (ADS)

    Baumbusch, Brian

    This thesis is about the process behind building, tuning, and composing music for a new set of metallophones called the "Lightbulb" instruments. This project began in 2011 and has continued to expand over the past two years: the first piece to be written for the instruments is titled Prana, and this thesis describes how the process of building and tuning the instruments informed the compositional process behind Prana. The premiere of Prana led to the formation of the Lightbulb Ensemble, which performs on these new instruments. The instruments and the group continue to develop.

    Nous étudions théoriquement les propriétés quantiques des faisceaux lumineux continus orthogonalement polarisés émis par un Oscillateur Paramétrique Optique (OPO) de type II contenant une lame biréfringente. Quand les axes optiques de la lame sont tournés par rapport à ceux du cristal paramétrique, un couplage apparaît entre les faisceaux signal et complémentaire qui entraîne un verrouillage de phase entre les deux modes et un fonctionnement à dégénérescence de fréquence à l'intérieur d'une zone d'accrochage. Les corrélations quantiques entre les deux faisceaux permettent de définir les zones dans l'espace des paramètres expérimentaux où les différents critères associés à l'intrication EPR utilisés en information quantique sont vérifiés.

    Les faisceaux continus orthogonalement polarisés émis par les Oscillateurs Paramétriques Optiques (OPO) de type II pompés au-dessus du seuil présentent au niveau quantique de fortes corrélations d'intensité et anti-corrélations de phase. Ils sont donc de très bons candidats pour générer des faisceaux intriqués en quadrature. Cependant, un phénomène de diffusion de phase rend difficile la mesure des propriétés sur la phase. Nous avons étudié théoriquement le régime stationnaire et les propriétés quantiques d'un OPO contenant une lame biréfringente. Le couplage linéaire qui en résulte entraîne un verrouillage en phase ainsi qu'un fonctionnement à dégénérescence en fréquence à l'intérieur d'une zone d'accrochage. L'expérience en cours au laboratoire a permis d'observer ce phénomène de verrouillage.

    Le kyste hydatique de la surrénale reste une affection exceptionnelle et une localisation inhabituelle du kyste hydatique, même dans les pays où l'hydatidose sévit à l’état endémique. Nous rapportons un cas de kyste hydatique surrénalien révélé par des douleurs de l'hypochondre droit. Le diagnostic a été évoqué en préopératoire sur les données de la tomodensitométrie abdominale qui avait objectivé une masse kystique surrénalienne droite. La sérologie hydatique était positive. Le traitement chirurgical avait consisté en une résection du dôme saillant et avait permis de conserver la glande. Le kyste était univésiculaire contenant un liquide eau de roche avec une membrane proligère. Les suites opératoires étaient simples. La surveillance à distance, échographique et immunologique, n'avait pas décelé de récidive avec un recul de deux ans PMID:26587122

    Cette these examine theoriquement deux aspects de la synchronisation des modes d'un laser. D'une part, on etudie l'influence de la desyntonisation de la frequence de modulation sur la stabilite des impulsions produites par la synchronisation modale AM. On montre que la desyntonisation provoque une perte de convergence intrinseque du processus de synchronisation active independante de la presence de bruit dans la cavite. La plage de convergence est d'autant plus etroite que le nombre de modes sous la courbe de gain est eleve. En pratique, elle est considerablement reduite par le bruit present dans la cavite. La synchronisation interferentielle, realisee a l'aide d'une cavite couplee contenant un element non-lineaire, est aussi etudiee. On decrit les principes generaux de la compression resultant de l'interference de deux impulsions. On evalue les performances realisables en fonction du taux de compression et de modulation de phase de l'element non-lineaire. Une etude detaillee du laser a interferometre de Michelson non-lineaire et non dispersif est presentee.

    The Coalition for Plasma Science (CPS) has established a plasma prize at the annual Intel International Science and Engineering Fair (ISEF). The 2006 prize was awarded for a project that investigated the correlation of GPS errors with various measures of near-earth plasma activity. The CPS is a broadly-based group of institutions and individuals whose goal is to increase the understanding of plasmas for non-technical audiences. In addition to the ISEF plasma award, CPS activities include maintaining a website, http://www.plasmacoalition.org; developing educational literature; organizing educational luncheon presentations for Members of Congress and their staffs; and responding to questions about plasmas. In addition, the CPS has begun as effort to examine the plasma content of state education standards with the goal of promoting the adoption of standards with appropriate plasma conten; e.g. are there three or four states of matter. The success of this and other activities depend on the voluntary labor of CPS members and associates. Please send an e-mail to the CPS at CPS@plasmacoalition.org for information if you would like to become involved in spreading the good word about plasmas.

    We report NMR and molecular modelling studies on two DNA duplexes containing a gap of one nucleotides. The difference between the two oligonucleotides lies in the central base face to the gap, a guanine or a cytosine. For the gapG, we observed in solution a B-form conformation where the guanine stacks in the helix. For the gapC, we reveal the existence of two species, one majority where the cytosine is inside the helix and a second for which the cytosine is extrahelical. Nous présentons une étude par RMN et modélisation moléculaire sur deux duplexes d'ADN contenant une lacune de un nucléotide. La différence entre les deux oligonucléotides réside dans la base centrale en face de la lacune, une guanine ou une cytosine. Pour le duplex appelé gapG, nous observons en solution une hélice de type B dans laquelle la guanine est empilée à l'intérieur de l'hélice. Dans le cas du duplex gapC, nous montrons l'existence de deux formes, l'une où la cytosine est à l'intérieur de l'hélice; la seconde où la cytosine est extra hélicale.

  3. Comment on "football-specific fitness testing: adding value or confirming the evidence?".

    Carling, Christopher; Collins, Dave

    2014-01-01

    The recent point-counter-point exchange arising from the article by Mendez-Villanueva and Buchheit (2013) (Football-specific fitness testing: Adding value or confirming the evidence? Journal of Sports Sciences, 31, 1503-1508) has generated an interesting debate on the real-world utility of fitness testing in professional association football (soccer). In the present authors' opinion, this exchange could also have been placed more in the context of the physical testing and subsequent benchmark profiling of the youth player within elite academy talent identification and development processes. This point is further strengthened by the current media debate at the time of writing on the development of elite youth football players in England and the Elite Player Performance Plan or EPPP (The Premier League. (2011). Elite Player Performance Plan. London: Author) published by the English Premier League as part of a vision for the future development of youth football in the League and throughout the English professional game. The EPPP recommends the implementation of a national database to enable comparison of Academy player performances against national physical testing "benchmark" profiles. In continuing the above debate, this letter questions the real-world utility and potential pitfalls of nationwide athletic benchmark profiling programmes for elite youth football. PMID:24878103

    To evaluate the retentive strength of 7 different luting agents in cement-retained implant abutment/analog assemblies. Fifty-six externally hexed dental implant abutment/analog assemblies and cast superstructures were divided randomly into 7 groups for cementation with each of the 7 luting agents. Five definitive cements tested were zinc phosphate cement, All-Bond 2, Maxcem, RelyX Luting cement, HY-Bond, and two provisional cements, ImProv and Premier. Cast superstructures were cemented onto the implant abutments and exposed to 1000 thermal cycles (0°C-55°C) and 100 000 cycles on a chewing simulator (75 N load). A universal testing machine was used to measure cement failure load of the assembled specimens. Cement failure load was evaluated with 1-way ANOVA and Duncan's multiple range analysis. Significant differences in cement failure loads were measured (P < .0001). Post hoc testing with Duncan's multiple range indicated 4 separate groupings. Maxcem and All-Bond 2 were comparable, having the greatest load failure. RelyX and zinc phosphate cement were analogous, and higher than HY-Bond. Improv and Premier constituted a pair, which demonstrated the lowest retentive values. Within the limitations of this in vitro study, Maxcem and All-Bond 2 are good candidates for cement-retained implant prostheses while concerning retention. PMID:24666355

    A middle-down LC/MS approach, for the rapid quantitation and characterization of site-specific methionine oxidation in a recombinant monoclonal IgG1 molecule, is described. An IgG1 antibody was digested with endoprotease LysC under limited proteolytic conditions to produce two major components; an antigen binding fragment (Fab) and a crystallizable fraction (Fc). These fractions were then reduced to produce three major species; light chain (LC), Fc/2 which is the C terminal region of the heavy chain (HC) and the N-terminal heavy chain region (Fd). These three fragments were separated by reversed-phase HPLC using a diphenyl column. The diphenyl column resolved site-specific methionine oxidation in all three subunits. Middle-down N-terminal sequencing with a LCT premier mass spectrometer was used to identify the sites of oxidation in the LC. Sites of oxidation in the Fc/2 were identified using middle-down collision-induced dissociation (CID) on a Qtof premier. This method allowed for the rapid quantitation and identification of oxidation on each methionine residue in an IgG1 molecule. PMID:20845446

    An N-terminal top-down sequencing approach was developed for IgG characterization, using high-resolution HPLC separation and collisionally activated dissociation (CAD) on a single-stage LCT Premier time of flight (TOF) mass spectrometer. Fragmentation of the IgG chains on the LCT Premier was optimized by varying the ion guide voltage values. Ion guide 1 voltage had the most significant effect on the fragmentation of the IgG chains. An ion guide 1 voltage value of 100 V was found to be optimum for the N-terminal fragmentation of IgG heavy and light chains, which are approximately 50 and 25 kDa, respectively. The most prominent ion series in this CAD experiment was the terminal b-ion series which allows N-terminal sequencing. Using this technique, we were able to confirm the sequence of up to seven N-terminal residues. Applications of this method for the identification of N-terminal pyroglutamic acid formation will be discussed. The method described could be used as a high-throughput method for the rapid N-terminal sequencing of IgG chains and for the detection of chemical modifications in the terminal residues.

    Frank and Gilovich (1988) found that teams with black uniforms were penalized by referees more than other teams that did not wear black uniforms in the U.S. National Football League (NFL), and the U.S. National Hockey League (NHL). This finding was examined for the referees in the Turkish Premier Soccer League (TPSL) for the soccer teams wearing or not wearing black uniforms during actual games. 30 male referees' (ages 22-45 years, M = 34.8) decisions were analyzed in a total of 2142 Turkish premier soccer league games played in 7 seasons. Using the number of red and yellow cards and penalty kicks teams drew as a penalty decision criteria, no significant differences were found between Turkish soccer teams wearing black uniforms or those not and the number of penalty kicks. This result, which was different from that of Frank and Gilovich's work, was discussed in relation to the social psychological point of view of different cultures and societies. PMID:15773692

    L'accouchement gémellaire différé définit un accouchement en deux ou plusieurs temps, avec l'expulsion spontanée d'un premier fœtus au deuxième ou au troisième trimestre, et un prolongement de la grossesse pour obtenir un accouchement du ou des fœtus restants en gestation le plus proche possible du terme. Cette technique est mise en œuvre, en cas de grossesse gémellaire pour prévenir la prématurité du fœtus restant après l'expulsion très prématurée d'un premier fœtus. Nous rapportons deux cas observés à la maternité du Centre Hospitalier de Creil avec des latences respectives de 3 et 52 jours pour lesquels nous discutons la prise en charge. PMID:25722777

    1998-05-01

    This is a quarterly report of CALSTART's progress with their programs. For the last quarter, CALSTART has performed the following work in support of the AlliedSignal turbogenerator project: We have taken prime turbogenerator marketing information, in the form of data sheets, posters and a new touchscreen computer interactive information program to two industry conferences that provided significant visibility and outreach for the AlliedSignal product. The first conference was EVS-13 (Electric Vehicle Symposium 13) October 11-18 in Osaka, Japan, the world's largest conference dedicated solely to electric vehicles and technology. AlliedSignal's turbogenerator display and information occupied the premier front location in the APU (auxiliary power unit) tower of the CALSTART industry exhibit and received substantial notice at a focused conference of more than 1,600 attendees. The exhibit was heavily attended and the turbogenerator received much interest. The second industry conference where CALSTART showcased the turbogenerator for marketing support was the NAEVI (North American Electric Vehicle and Infrastructure) Conference in San Diego, California, December 11-13. In addition to holding the premier spot in the display exhibit, CALSTART transported the turbogenerator itself to augment the display location. This conference represented the biggest American conference on EVS in 1996 and was well attended. The AlliedSignal display and information were utilized by several hundred people directly and by several hundred more as a central part of the exhibit they visited, creating a favorable impression of the technology.

  11. An examination of the frequency and severity of injuries and incidents at three levels of professional football

    Hawkins, R. D.; Fuller, C. W.

    1998-01-01

    OBJECTIVE: To assess the risk of injury to professional footballers during European international and English Premier and First Division league matches. METHODS: Videotaped recordings of 29, 49, and 93 matches from the 1996 European Championship, 1996/1997 English Premier season and 1994 to 1997 English First Division seasons respectively were analysed. During each match, several relevant variables, including the number of fouls, injuries, time of incident, player identity, and injury mechanism, were recorded. RESULTS: Significantly more free kicks were awarded during international matches than during league matches; however, there were no significant differences between the numbers of free kicks awarded over the three First Division seasons assessed. Between 1.7 and 3.0% of fouls resulted in a player requiring treatment for injury, but only 15-28% of all injuries resulted from foul play. In all "non-foul" situations, in which injury resulted, at least 60% still involved player to player contact. No significant differences in injury frequency were observed between playing positions or match halves. CONCLUSIONS: The results equate to a total of 808 players per season from the estimated 2600 players in the four English professional football leagues sustaining a match injury that caused them to miss at least one game. The large number of underlying "non-injury" incidents is identified as the reason for this level of injury rather than a higher ratio of "injury" to "non-injury" incidents in professional football compared with other occupations.

    The National Family Planning Working Conference convened on August 10-16, 1982 in Beijing, China. Among the 250 conferees were family planning representatives from various provinces, cities, autonomous regions, the People's Liberation Armt, representatives of partial progressive areas, counties, communes, the Central Committee, State Council, All China Women's Federation, All China Federation of Trade Unions, journalists and population theorists. Topics of discussion included the current situation of family planning work, how to implement the Central Committee's directive on improving family planning work, and the relationship between population law and population development by the year 2000. On August 18 Premier Zhao Ziyang told various representatives at a meeting that population control was a longterm national policy and emphasized its importance in long-range economic and social planning. The Vice-premier of the Chinese People's Political Consultative Conference, Wang Shoudao, implored the representatives to understand the directive's contents and said family planning would serve later generations. The Chairman of the National Family Planning Commission, Quian Xinzhong, reviewed the current population situation, noting the encouraging fact that the birth rate for the first 6 months of 1982 was higher than the first 6 months in 1981 by only 1/1000. In order to raise birth control work to a new level, he suggested the following steps: strengthen family planning propaganda; strenuously follow the policy of 1 child per family; obtain permission to have a 2nd child; oppose unplanned births; establish various birth control responsibility systems; and improve contraceptive research and techniques.

    Space age had its world premiere at the large-screen Spaceport Theater at Cape Canaveral/Kennedy Spaceport. The first program was screened for invited guests who, that morning, also witnessed a launch of the Space Shuttle. Since that mission carried the first Japanese astronaut, it was a nice tie-in to the substantial co-production participation of space age by NHK Japan. A special press conference for the series and a twenty-minute preview reel was screened for journalists who were also at the Cape for the shuttle launch. Numerous first-hand newspaper articles were generated. CNN ran part of the preview reel. The first episode in the series, `The Quest for Planet Mars,` then ran twice a day for a week, prior to the Public Broadcasting Service broadcast on an Imax format screen at the Spaceport theater. The program was seen by thousands of visitors. Space age also had a special premier at the National Academy of Sciences in Washington, DC with some 400 special guests, including scientists and government agency representatives.

    Contact sports have long been a part of human existence. The two earliest recorded organized contact games, both of which still exist, include Royal Shrovetide Football played since the 12(th) century in England and Caid played since 1308 AD in Ireland. Rugby is the premier contact sport played throughout the world with the very popular derivative American football being the premier contact sport of the North American continent. American football in the USA has on average 1,205,037 players at the high school and collegiate level per year while rugby in the USA boasts a playing enrollment of 457,983 at all levels. Recent media have highlighted injury in the context of competitive contact sports including their long-term sequelae such as chronic traumatic encephalopathy (CTE) that had previously been underappreciated. Blunt cerebrovascular injury (BCVI) has become a recognized injury pattern for trauma; however, a paucity of data regarding this injury can be found in the sports trauma literature. We present a case of an international level scrum-half playing Rugby Union at club level for a local non-professional team, in which a player sustained a fatal BCVI followed by a discussion of the literature surrounding sport related BCVI.

    Allaire Tanguay, Dominique

    Ce mémoire présente l'étude d'un système de trigénération ou CCHP (combined cooling, heating and power) au gaz naturel fournissant les besoins thermiques à un immeuble à logement typique de 13 étages. Un groupe électrogène permettant de générer de l'électricité tout en fournissant de l'eau chaude assure le chauffage du bâtiment et de l'eau chaude sanitaire tandis qu'une machine à absorption ammoniac-eau permet de transformer cette chaleur en puissance frigorifique afin de climatiser le bâtiment en période chaude. Le modèle de cette machine à absorption a spécialement été conçu pour fonctionner avec une température de désorption basse et permet d'évaluer les performances de telles machines dans des situations hors design. Ce modèle à été vérifié à l'aide d'autres modèles avérés et propose des coefficients de performance de l'ordre de 0,7 à 0,8. L'évaluation des performances horaires de ce système est présentée pour une année standard sous trois climats canadiens. Ces performances sont ensuite comparées aux différentes méthodes employées pour assurer ces besoins ainsi que pour générer l'électricité supplémentaire. Les résultats démontrent d'excellentes performances même lorsque comparées aux plus récentes technologies. Les résultats passent d'une légère augmentation de la consommation de gaz naturel dans un climat chaud comme Toronto à une importante réduction dans un climat froid comme Edmonton. Ce système permet donc de combler les besoins thermiques d'un bâtiment tout en générant de l'électricité dans des périodes de pointes annuelles et possiblement journalières. Plusieurs études dont notamment l'optimisation du système et le couplage à d'autres types de bâtiment permettrait cependant de mieux évaluer les possibilités complètes de la trigénération.

This approach allows to describe the electrodynamic state of the motor by taking into account, in a natural way, the influence of saturation and eddy-currents, as well as the nonlinearities due to the variable flux operation. Equations are approximated via a finite element formulation which leads to a finite dimensional dynamical system to which the techniques of optimal control may be applied. The generality of the methodology allows to treat various criteria. The objective aimed in this paper is to force the motor torque to follow a given input, especially under initially demagnetized conditions and with, naturally, constraints on the currents. For this purpose the criterion will be chosen as a norm of the difference between the electromagnetic torque and a given reference torque. Numerical simulations are presented for the case of a squirrel-cage rotor and for a solid iron rotor. Results are compared with those deduced from strategies based on lumped-parameter models. Torque responses obtained with field-oriented control method adapted to the case of flux-variable operation are also presented. Finally a modification of the criterion is proposed for identifying the command which allows to obtain the larger torque during transient states. Dans cet article on traite le problème du contrôle optimal à flux libre d'un moteur asynchrone considéré comme un système à paramètres répartis gouverné par une équation de diffusion non linéaire. Cette approche permet de décrire l'état électrodynamique de la machine en prenant naturellement en compte les effets de la saturation et des courants induits, ainsi que les non-linéarités liées au fonctionnement à flux variable.

    The dismantling of the 1st French generation UNGG (Uranium Naturel Graphite Gas) nuclear reactors operated by the French utility, EDF (Electricité de France) will generate around 17,000 tons of irradiated graphite wastes that have to be disposed of. 14C is one of the main radioactive dose contributors over 10,000 years. For the management of this waste, it is mandatory to get an accurate estimation of 14C. The general aim of our work is therefore to simulate the behavior of 14C in nuclear graphite and to elucidate the coupled and decoupled effects of temperature, irradiation and radiolytic corrosion that mainly influence 14C behavior in graphite during reactor operation. This paper focuses on the behavior of 13C implanted into nuclear graphite and used to simulate the presence of 14C displaced from its original structural site through recoil during neutron irradiation. It aims at evaluating both the temperature and the disorder level of the implanted graphite structure effects on 13C migration using two complementary techniques, NRA and SIMS, to evaluate the 13C distribution at the millimeter and micrometer lateral scales respectively. Raman micro-spectroscopy is used to check the graphite structure evolution. The results show that 13C is not released up to 1600 °C whatever the initial structural disorder level of the implanted graphite. This might be due to the fact that 13C might be trapped into interstitial clusters. The extrapolation of our results to the behavior of 14C shows that reactor temperatures (200-500 °C) did not induce any 14C release. Moreover, as long as there is no gasification of the graphite matrix, high temperatures tend to stabilize 14C into the remaining graphite structure. This fact has to be considered in case of high temperature purification of 14C from irradiated graphite.

    Synergistic exploitation of redundant and complementary information from independent observations of the same target remains a major issue in atmospheric remote sounding and increasing attention is devoted to investigate optimized or innovative methods for the combination of two or more measured data sets. This paper focuses on the synergy between middle infrared and millimeter-wave limb sounding measurements of atmospheric composition and temperature and reports the results of a study conducted as part of the preparatory activities of the PREMIER (Process Exploration through Measurements of Infrared and millimeter-wave Emitted Radiation) mission candidate to the Core Missions of the European Space Agency (ESA) Earth Explorer 7. The activity was based on data acquired by the MIPAS-STR (Michelson Interferometer for Passive Atmospheric Sounding - STRatospheric aircraft) and MARSCHALS (Millimetre-wave Airborne Receivers for Spectroscopic CHaracterisation in Atmospheric Limb Sounding) instruments on-board the high-altitude research aircraft M-55 Geophysica during the flight of the PremierEx (PREMIER Experiment) campaign on 10 March 2010 from Kiruna, Sweden, for observation of the Arctic upper troposphere and lower stratosphere. The cloud coverage observed along the flight provided representative test cases to evaluate the synergy in three different scenarios: low clouds in the first part, no clouds in the central part and high tropospheric clouds at the end. The calculation of synergistic profiles of four atmospheric targets (i.e., O3, HNO3, H2O and temperature) was performed using a posteriori combination of individual retrieved profiles, i.e., Level 2 (L2) data rather than simultaneous inversion of observed radiances, i.e., Level 1 (L1) data. An innovative method of data fusion, based on the Measurement Space Solution (MSS) was applied along with the standard approach of inversion of MARSCHALS spectral radiances using MIPAS-STR retrieval products as a priori

    Synopsis Objective The maintenance of youthful skin appearance is strongly desired by a large proportion of the world's population. The aim of the present study was therefore to evaluate the effect on skin wrinkling, of a combination of ingredients reported to influence key factors involved in skin ageing, namely inflammation, collagen synthesis and oxidative/UV stress. A supplemented drink was developed containing soy isoflavones, lycopene, vitamin C and vitamin E and given to post-menopausal women with a capsule containing fish oil. Method We have performed a double-blind randomized controlled human clinical study to assess whether this cocktail of dietary ingredients can significantly improve the appearance of facial wrinkles. Results We have shown that this unique combination of micronutrients can significantly reduce the depth of facial wrinkles and that this improvement is associated with increased deposition of new collagen fibres in the dermis. Conclusion This study demonstrates that consumption of a mixture of soy isoflavones, lycopene, vitamin C, vitamin E and fish oil is able to induce a clinically measureable improvement in the depth of facial wrinkles following long-term use. We have also shown, for the first time with an oral product, that the improvement is associated with increased deposition of new collagen fibres in the dermis.

    The electrochemical oxidation, in aqueous medium, of a 3,4-ethylenedioxythiophene monomer functionalized by a sulfonate group exhibiting cation-exchange properties, allows the synthesis of a new type of water-soluble material. In order to synthesize in water, by oxidative electropolymerization, polymer films of controlled thickness containing attached sulfonate groups, we have investigated the polymerization of the functionalized monomer in the presence of the unsubstituted one without supporting electrolyte. Using an equimolar mixture (0.01 mol/l) of both monomers, copolymers exhibiting cation exchange abilities have been synthesized. As an example, th easy incorporation of hexaamine-ruthenium(III) into one of these copolymers is briefly reported. L'oxydation électrochimique en milieu aqueux d'un monomère de type 3,4- éthylènedioxythiophène fonctionnalisé par un groupement sulfonate permet d'envisager la synthèse d'un nouveau type de polymère hydrosoluble. Afin d'obtenir électrochimiquement en milieu aqueux, un film de polymère d'épaisseur contrôlée contenant des groupements sulfonates, nous avons evisagé de polymériser ce monomère en présence de son homologue non substitué. En partant d'un mélange équimolaire (0.01 mol/l) des deux monomères et en l'absence d'électrolyte support, nous avons synthétisé un matériau possédant des propriétés d'échange de cations. A titre d'exemple, nous présentons brièvement l'incorporation d'un complexe hexaaminé du ruthénium(III) dans un de ces copolymères.

L'influence du pourcentage en sel de lithium dans l'électrolyte liquide, de la proportion de silice dans le copolymère sec et de la température sur la capacité d'absorption est étudiée. L'évolution de la conductivité en fonction de la composition de l'électrolyte-gel et de la température ainsi que l'étude de la solvatation de l'ion Li^+ par spectroscopie RAMAN ont permis de proposer un modèle de conductivité ionique pour ces matériaux. Après avoir déterminé le domaine d'électroactivité des gels, l'évolution des spectres d'impédance à l'interface Li / gel est interprétée par le modèle “couche polymère solide" (SPL).

    El estigma relacionado con el VIH/SIDA continúa siendo un obstáculo para la prevención primaria y secundaria del VIH. Las consecuencias para las personas que viven con la enfermedad han sido muy documentadas y continúan siendo una gran preocupación para las personas que proveen servicios de salud y para aquellas que investigan el tema. Estas consecuencias son preocupantes cuando el estigma emana de profesionales de la salud porque se puede limitar el acceso a los servicios. Uno de los principales obstáculos para la investigación del estigma relacionado con el VIH en Puerto Rico es la falta de instrumentos cuantitativos para evaluar las manifestaciones del estigma entre profesionales de la salud. El objetivo principal de este estudio fue desarrollar y probar las propiedades psicométricas de una escala sobre el estigma relacionado con el VIH/SIDA culturalmente apropiada para personas que proveen servicios de salud puertorriqueñas y desarrollar una versión corta de la escala que pudiera usarse en escenarios clínicos con tiempo limitado. El instrumento desarrollado estuvo basado en evidencia cualitativa recopilada entre profesionales y estudiantes de profesiones de la salud puertorriqueños/as (n=80) y administrado a una muestra de 421 profesionales de la salud en adiestramiento. La escala contenía 12 dimensiones del estigma relacionado con el VIH/SIDA. El análisis cuantitativo corroboró 11 de ellas, teniendo como resultado un instrumento con validez y confiabilidad satisfactoria. Estas dimensiones, a su vez, fueron subcomponentes de un factor de estigma general superior. PMID:20333258

Our program is divided into two parts: building envelope research, which focuses on the structural elements that enclose a building (walls, roofs and foundations), and materials research, which concentrates on the materials within the envelope systems (such as insulation). The building envelope provides the thermal barrier between the indoor and outdoor environment, and its elements are the key determinants of a building's energy requirements that result from the climate where it is located.

    The goal of this LDRD project has been to create LATIS3D--the world's premier computer program for laser-tissue interaction modeling. The development was based on recent experience with the 2D LATIS code and the ASCI code, KULL. With LATIS3D, important applications in laser medical therapy were researched including dynamical calculations of tissue emulsification and ablation, photothermal therapy, and photon transport for photodynamic therapy. This project also enhanced LLNL's core competency in laser-matter interactions and high-energy-density physics by pushing simulation codes into new parameter regimes and by attracting external expertise. This will benefit both existing LLNL programs such as ICF and SBSS and emerging programs in medical technology and other laser applications.

    The laboratory mouse shares the majority of its protein-coding genes with humans, making it the premier model organism in biomedical research, yet the two mammals differ in significant ways. To gain greater insights into both shared and species-specific transcriptional and cellular regulatory programs in the mouse, the Mouse ENCODE Consortium has mapped transcription, DNase I hypersensitivity, transcription factor binding, chromatin modifications and replication domains throughout the mouse genome in diverse cell and tissue types. By comparing with the human genome, we not only confirm substantial conservation in the newly annotated potential functional sequences, but also find a large degree of divergence of sequences involved in transcriptional regulation, chromatin state and higher order chromatin organization. Our results illuminate the wide range of evolutionary forces acting on genes and their regulatory regions, and provide a general resource for research into mammalian biology and mechanisms of human diseases.

    In this paper, we show a new technique to analyze families of rankings. In particular, we focus on sports rankings and, more precisely, on soccer leagues. We consider that two teams compete when they change their relative positions in consecutive rankings. This allows to define a graph by linking teams that compete. We show how to use some structural properties of this competitivity graph to measure to what extend the teams in a league compete. These structural properties are the mean degree, the mean strength, and the clustering coefficient. We give a generalization of the Kendall's correlation coefficient to more than two rankings. We also show how to make a dynamic analysis of a league and how to compare different leagues. We apply this technique to analyze the four major European soccer leagues: Bundesliga, Italian Lega, Spanish Liga, and Premier League. We compare our results with the classical analysis of sport ranking based on measures of competitive balance. PMID:24387553

    This paper suggests a new method for cricket team selection using data envelopment analysis (DEA). We propose a DEA formulation for evaluation of cricket players in different capabilities using multiple outputs. This evaluation determines efficient and inefficient cricket players and ranks them on the basis of DEA scores. The ranking can be used to choose the required number of players for a cricket team in each cricketing capability. A real dataset, Indian Premier League 4 (IPL 2011), cricket players having various capabilities is used to choose the best cricket team. The proposed method has the advantage of considering multiple factors related to the performance of players in multiple capabilities collected from IPL 4 and aggregates their scores using a linear programming DEA model. This DEA Aggregation gives the scores of players objectively instead of using subjective computations. The proposed DEA method can be used to form a national cricket team from several clubs or a team of top cricketers. PMID:24444231

    Moving images are a powerful medium for analyzing, exploring and visually communicating complex concepts, and they are also the premiere medium for contemporary storytelling. Animation is particularly adept for explaining complex concepts and also for creating emotional messages. On a practical level animation can be free from the production constraints and the expense of live action filming. This presentation shows and explains a variety of Earth-inspired animated sequences produced by the Art+Media Research Group at the Earth Observatory of Singapore. These animations have been used in a variety of interdisciplinary projects with multiple roles: sometimes to clearly explain a concept, others to elicit a feeling, or to present an emotion that facilitates learning. The projects reviewed range from scientific documentaries, to narrative shorts and interactive games. http://art-science-media.com/

    The TREAT reactor, fueled by a dilute dispersion of fully enriched UO/sub 2/ in graphite, has been a premier transient testing facility since 1959. A major Upgrade of the reactor is in progress to enhance its transient testing capability in support of the LMFBR safety program. The TREAT Upgrade (TU) reactor features a modified central zone of the core with higher fissile loadings of the same fuel, clad in Inconel to allow operation at higher temperatures. The demanding functional requirements on the reactor necessitated the use of unique features in the core design which, in turn, presented major calculational complexities in the analysis. Special design methods had to be used in many cases to treat these complexities. The addition of an improved Reactor Control System, a safety grade Plant Protection System and an enhanced Coolant/Filtration System produces a reactor that can meet the functional requirements on the reactor in a safe manner.

    Most physicists are familiar with the challenge of teaching physics to non-science students. At Bentley College, a premier business university, we have unique challenges and opportunities.

    The joint U.S. and German Stratospheric Observatory for Infrared Astronomy (SOFIA) will be a premier facility for studying the physics and chemistry of the interstellar medium and the stellar evolution process for many decades. SOFIA's first-generation instrument complement includes broadband imagers, moderate resolution spectrographs capable of resolving broad features due to dust and large molecules, and high resolution spectrometers suitable for kinematic studies of molecular and atomic gas lines at km/s resolution. SOFIA spectroscopic science applications will be discussed, with special emphasis on investigations related to infrared spectroscopy of astrophysical gas, grains, and ices. First light images and early science results related to these topics will be presented.

  1. The Role of Bacterial Spores in Metal Cycling and Their Potential Application in Metal Contaminant Bioremediation.

    Bacteria are one of the premier biological forces that, in combination with chemical and physical forces, drive metal availability in the environment. Bacterial spores, when found in the environment, are often considered to be dormant and metabolically inactive, in a resting state waiting for favorable conditions for them to germinate. However, this is a highly oversimplified view of spores in the environment. The surface of bacterial spores represents a potential site for chemical reactions to occur. Additionally, proteins in the outer layers (spore coats or exosporium) may also have more specific catalytic activity. As a consequence, bacterial spores can play a role in geochemical processes and may indeed find uses in various biotechnological applications. The aim of this review is to introduce the role of bacteria and bacterial spores in biogeochemical cycles and their potential use as toxic metal bioremediation agents. PMID:27227313

    The quality of the steel used for most galvanizing (and tinplate) applications makes scrap derived from their production and use a premier solid charge material for steelmaking. In 1989 the AISI created a Task Force to define the issues and to recommend technologically and economically sound approaches to assure continued, unhindered recyclability of the growing volume of galvanized scrap. The AISI program addressed the treatment of full-sized industrial bales of scrap. The current, on-going MRI (US)--Argonne National Laboratory program is focused on ``loose`` scrap from industrial and post-consumer sources. Results from these programs, issues of scrap management from source to steel melting, the choices for handling zinc in iron and steelmaking and the benefits/costs for removal of zinc (and lead) from scrap prior to melting in BOF and foundry operations are reviewed in this paper.

    Today`s skills will be obsolete in the year 2000. That workforce will require a much higher degree of technical sophistication and adaptability. Enormous demands will be made of DOE contractor training departments even as federal deficit reduction actions increasingly restrict resources and as the emergence of electronic performance support systems appear to diminish the need for training. True training will still be required but they must, and can, train better, faster, and cheaper. These goals are attainable by implementing the implications of performance-based training and by focusing on learning instead of on teaching. (Indeed, ability to learn efficiently and rapidly will be the premier talent in the next century.) Training Departments must dedicate themselves to changing performance, not to teaching classes. The best training department of the future will have no {open_quotes}instructors{close_quotes}. Trainingforce 2000 will look and function much differently.

    This document was prepared to support the Smart Buildings-Material Testing and Rating Centres (SB-2) activity of the Asia-Pacific Economic Cooperation (APEC) Energy Smart Communities Initiative (ESCI). The ESCI was put forward by APEC Leaders at the 2010 meeting in Japan. APEC is the premier forum for facilitating economic growth, cooperation, trade and investment in the Asia-Pacific region. This document addresses the testing and certification of building products and equipment to support building energy codes, focusing specifically on energy-efficient factory-built windows. It sets forth a proposed structure for an APEC economy to establish a testing, rating, certification, and labeling program for efficient factory-built windows. In the context of this document, efficient windows would be windows made with insulating glass (IG) and an efficient frame assembly. The minimum efficiency metric (or thermal performance) for these windows is not quantified in this document and would generally be established by a governmental agency.

    Continuous miner methods dominate underground while dragline stripping is today's and tomorrow's favored method on surface. Poor roof conditions in Australian underground mines and the need to operate more efficient surface mines in view of rising fuel costs are key factors in determining the mining methods for the country's premier cash commodity - coal. These and other new developments in underground and surface mining in Australia were discussed in detail at the Australian Coal Association's 1980 coal conference which was held last April in Surfers Paradise, Queensland. Two papers presented at the conference form the basis of this article; H.L. Pearce, general superintendent of the Steel Division Collieries of the Broken Hill Proprietary Company, described underground mining and K.J. Foots, manager of the Utah Development Company's Blackwater mine, talked about surface mining.

    It is a common misconception that plasma furnace technology only has application for exotic and very high temperature processes. With the increasing importance placed on waste minimization and the environmental constraints imposed on heavy metals present in byproducts from mainstream operations, plasma technology is finding widespread application. Tetronics is a premier supplier of plasma tundish heating systems for the steel industry. More recently the company has found growing interest in electric arc furnace dust treatment, lead blast furnace slag treatment and metal recovery, copper, nickel and cobalt scavenging from primary smelter slags, dross treatment, platinum group metals (PGM) recovery from catalysts and vitrification and detoxification of heavy metal contaminated waste byproducts. The principal advantages of the plasma arc technology are the close metallurgical control of the furnace environment, minimal off-gas handling requirements and overall high energy efficiency of the processes. A number of applications in the ferrous and non-ferrous metals industry are described.

    2010-01-01

    Health literacy, cited as essential to achieving Healthy People 2010's goals to "increase quality and years of healthy life" and to "eliminate health disparities," is defined by Healthy People as "the degree to which individuals have the capacity to obtain, process, and understand basic health information and services needed to make appropriate health decisions." Accessibility, by definition, the aforementioned "capacity to obtain," thus is health literacy's primary prerequisite. Accessibility's designation as the global gateway to health literacy is predicated also on life's realities: global aging and climate change, war and terrorism, and life-extending medical and technological advances. People with diverse access needs are health professionals' raison d'être. However, accessibility, consummately cross-cultural and universal, is virtually absent as a topic of health promotion and practice research and scholarly discussion of health literacy and equity. A call to action to place accessibility in its rightful premier position on the profession's agenda is issued. PMID:18955546

    Mesoamerican peoples had a long history of cacao use—spanning more than 34 centuries—as confirmed by previous identification of cacao residues on archaeological pottery from Paso de la Amada on the Pacific Coast and the Olmec site of El Manatí on the Gulf Coast. Until now, comparable evidence from San Lorenzo, the premier Olmec capital, was lacking. The present study of theobromine residues confirms the continuous presence and use of cacao products at San Lorenzo between 1800 and 1000 BCE, and documents assorted vessels forms used in its preparation and consumption. One elite context reveals cacao use as part of a mortuary ritual for sacrificial victims, an event that occurred during the height of San Lorenzo's power. PMID:21555564

    2011-04-01

    Many different materials and treatment options are available in esthetic and restorative dentistry. Various newer products, such as pressed ceramics, offer enhanced functionality; however, in thinner dimensions, they lack the inherent esthetic beauty of traditional materials such as feldspathic porcelain. As patient demands for better esthetics have increased in recent years, so too has the need for restorative materials that closely mimic the patient's natural dentition. Initially used for the creation of porcelain dentures, feldspathic porcelain has emerged as the premier esthetic material for custom veneer restorations. In recent years, the use of hand-layered powder/liquid feldspathic porcelain has been revived based on its highly esthetic values and little-to-no preparation requirements. By keeping preparation to a minimum, less tooth structure is lost and procedures are much less invasive, which is exactly what patients desire. PMID:21560742

    2013-12-01

    In this paper, we show a new technique to analyze families of rankings. In particular, we focus on sports rankings and, more precisely, on soccer leagues. We consider that two teams compete when they change their relative positions in consecutive rankings. This allows to define a graph by linking teams that compete. We show how to use some structural properties of this competitivity graph to measure to what extend the teams in a league compete. These structural properties are the mean degree, the mean strength, and the clustering coefficient. We give a generalization of the Kendall's correlation coefficient to more than two rankings. We also show how to make a dynamic analysis of a league and how to compare different leagues. We apply this technique to analyze the four major European soccer leagues: Bundesliga, Italian Lega, Spanish Liga, and Premier League. We compare our results with the classical analysis of sport ranking based on measures of competitive balance.

    Acculturation has been associated with health-related behaviors in African Americans. We sought to determine if there is a relationship between acculturation and dietary intake in African Americans. African Americans in the PREMIER trial completed the African American Acculturation Scale (AAAS) and 2 nonconsecutive 24-h dietary recalls (n = 238). Analysis of variance (ANOVA) and canonical correlation were used to assess relationships between acculturation and dietary intakes. Canonical correlation (p = 0.05) showed that traditional African Americans had lower intakes of fruits/vegetables and milk/dairy with higher intakes of fats, meat, and nuts. This pattern was supported by differences in the ANOVA. African American acculturation is related to dietary intake. These findings have implications for the design of cancer-related public health messages targeted to African Americans. PMID:16015458

Focus of research efforts are adaptive systems for shape control, noise reduction and vibration control of both fixed and rotary wing aircraft as well as for lift optimisation of fixed wing aircraft. Two outstanding adaptive systems which have been pushed ahead in cooperation with Airbus Germany and Eurocopter Germany are adaptive servo flaps for helicopter rotor blades and innovative high lift devices for fixed wing aircraft which both were tested in flight for the first time representing world premieres. In this paper various examples of adaptive systems are presented which were developed and realized by EADS in recent years.

    This paper is an account of the social history of the Round House Gaol in Fremantle, Western Australia and of those lunatics that were gathered together into its closed geographical space. The first permanent structure, perched on the most elevated and prominent site in Fremantle, was a gaol; the design for which was based on Jeremy Bentham's Panopticon or Inspection House, created for the purpose of surveillance and control of inmates. Visible in 1997, the Round House still stands as a dominant, physical marker of the landscape, ranking as a premier historical tourist attraction in Western Australia. But its actual use as a place for the containment of lunatics is only cursorily alluded to. This paper addresses the previously ignored period of 1830-1850. PMID:10095465

    2009-01-01

    Introduced as a federal-provincial cost-sharing program in the 1960s, Canadian Medicare arose in the context of competing provincial models implemented by Saskatchewan, Alberta, and British Columbia. This article examines Bennettcare in British Columbia which, unlike the Saskatchewan and Alberta models, has never been analysed historically. Named after Premier W. A. C. Bennett, Bennettcare initially attempted to balance public support for a government-sponsored health insurance program with the free enterprise ideology espoused by the followers of Social Credit, the insurance industry, and the British Columbia Medical Association. However, in order to receive cost-sharing dollars from the federal government, Bennett was eventually compelled to change the design features in order to comply with the federal government's requirements of universality and public administration, morphing Bennettcare into Saskatchewan-style Medicare.

She has made innumerable contributions to the field of safety over the past 25 years through her work with regulatory and federal agencies. Changing organizational culture from a "blame culture" to a "safety culture" is one notable challenge facing organizations. The airline industry has achieved significant changes in its safety culture by virtually eliminating a power hierarchy in the cockpit, a worthy example for operating rooms. Redesigning care delivery processes will minimize the opportunity for error if efforts are made to avoid reliance on memory, automate repetitive functions, reduce the number of steps involved, or use protocols when appropriate. The sophistication of consumers and the emergence of organizations like the Leap Frog Group will continue to challenge health care providers and potentially accelerate safety improvements.

    2014-01-01

    Optical imaging with spectroscopic vibrational contrast is a label-free solution for visualizing, identifying, and quantifying a wide range of biomolecular compounds in biological materials. Both linear and nonlinear vibrational microscopy techniques derive their imaging contrast from infrared active or Raman allowed molecular transitions, which provide a rich palette for interrogating chemical and structural details of the sample. Yet nonlinear optical methods, which include both second-order sum-frequency generation (SFG) and third-order coherent Raman scattering (CRS) techniques, offer several improved imaging capabilities over their linear precursors. Nonlinear vibrational microscopy features unprecedented vibrational imaging speeds, provides strategies for higher spatial resolution, and gives access to additional molecular parameters. These advances have turned vibrational microscopy into a premier tool for chemically dissecting live cells and tissues. This review discusses the molecular contrast of SFG and CRS microscopy and highlights several of the advanced imaging capabilities that have impacted biological and biomedical research.

    Initial proposal summary: The evolution of antibiotic-resistant mutants among bacteria (superbugs) is a persistent and growing threat to public health. In many ways, we are engaged in a war with these microorganisms, where the corresponding arms race involves chemical weapons and biological targets. Just as advances in microelectronics, imaging technology and feature recognition software have turned conventional munitions into smart bombs, the long-term objectives of this proposal are to develop highly effective antibiotics using next-generation biomolecular modeling capabilities in tandem with novel subatomic feature detection software. Using model compounds and targets, our design methodology will be validated with correspondingly ultra-high resolution structure-determination methods at premier DOE facilities (single-crystal X-ray diffraction at Argonne National Laboratory, and neutron diffraction at Oak Ridge National Laboratory). The objectives and accomplishments are summarized.

    This significant new study of the decision to build the Space Shuttle explains the Shuttle's origins and early development. In addition to internal NASA discussions, this work details the debates in the late 1960s and early 1970s among policymakers in Congress, the Air Force, and the Office of Management and Budget over the roles and technical designs of the Shuttle. Examining the interplay of these organizations with sometimes conflicting goals, the author not only explains how the world's premier space launch vehicle came into being, but also how politics can interact with science, technology, national security, and economics in national government. The weighty policy decision to build the Shuttle represents the first component of the broader story: future NASA volumes will cover the Shuttle's development and operational histories.

    The Deep Underground Neutrino Experiment (DUNE) will be a premier facility for exploring long-standing questions about the boundaries of the standard model. Acting in concert with the liquid argon time projection chambers underpinning the far detector design, the DUNE photon detection system will capture ultraviolet scintillation light in order to provide valuable timing information for event reconstruction. To maximize the active area while maintaining a small photocathode coverage, the experiment will utilize a design based on plastic light guides coated with a wavelength-shifting compound, along with silicon photomultipliers, to collect and record scintillation light from liquid argon. This report presents recent preliminary performance measurements of this baseline design and several alternative designs which promise significant improvements in sensitivity to low-energy interactions.

    This paper charts the history and debates surrounding the introduction of academic, university-based training of nurses in South Africa. This was a process that was drawn out over five decades, beginning in the late 1930s. For nurses, university training was an important part of a process of professionalization; however, for other members of the medical community, nursing was seen as being linked to women's service work. Using the case-study of the University of the Witwatersrand, one of South Africa's premier universities and the place in the country to offer a university-based nursing program, we argue that an historical understanding of the ways in which nursing education was integrated into the university system tells us a great deal about the professionalization of nursing. This paper also recognises, for the first time, the pioneers of this important process. PMID:21994840

    Nous avons concu, implemente puis valide une nouvelle methode d'approximation des forces aerodynamiques non stationnaires a l'aide des polynomes orthogonaux de Chebyshev. Cela represente une contribution originale dans l'analyse des interactions aeroservoelastiques. La premiere serie de resultats obtenus par cette nouvelle methode (erreurs d'approximation des forces aerodynamiques non stationnaires) est comparee avec les resultats des methodes LS et de Pade. La deuxieme serie de resultats (vitesses et frequences de battement obtenues avec cette nouvelle methode) est comparee avec celles obtenues par les methodes classiques LS et de Pade. Ces deux series de resultats obtenus par notre methode et par les deux methodes classiques LS et de Pade sont validees sur trois types differents d'avions: l'ATM (Aircraft Test Model), le F/A-18 en collaboration avec les laboratoires de la NASA Dryden Flight Research Center, et enfin le Challenger CL-604 de Bombardier Aeronautique.

    Over the past seven years, efforts under the present Grant have been aimed at being able to apply modern Computational Fluid Dynamics to the design of high-speed engine inlets. In this report, a review of previous design capabilities (prior to the advent of functioning CFD) was presented and the example of the NASA 'Mach 5 inlet' design was given as the premier example of the historical approach to inlet design. The philosophy used in the Mach 5 inlet design was carried forward in the present study, in which CFD was used to design a new Mach 10 inlet. An example of an inlet redesign was also shown. These latter efforts were carried out using today's state-of-the-art, full computational fluid dynamics codes applied in an iterative man-in-the-loop technique. The potential usefulness of an automated machine design capability using an optimizer code was also discussed.

    The PC12 clone, developed from a pheochromocytoma tumor of the rat adrenal medulla, has become a premiere model for the study of neuronal differentiation. When treated in culture with nanomolar concentrations of nerve growth factor, PC12 cells stop dividing, elaborate processes, become electrically excitable, and will make synapses with appropriate muscle cells in culture. The changes induced by nerve growth factor lead to cells that, by any number of criteria, resemble mature sympathetic neurons. These changes are accompanied by a series of biochemical alterations occurring in the membrane, the cytoplasm, and the nucleus of the cell. Some of these events are independent of changes in transcription, while others clearly involve changes in gene expression. A number of the alterations seen in the cells involve increases or decreases in the phosphorylation of key cellular proteins. The information available thus far allows the construction of a hypothesis regarding the biochemical basis of PC12 differentiation. PMID:2647474

    Metal-silicon junctions are crucial to the operation of semiconductor devices: aggressive scaling demands low-resistive metallic terminals to replace high-doped silicon in transistors. It suggests an efficient charge injection through a low Schottky barrier between a metal and Si. Tremendous efforts invested into engineering metal-silicon junctions reveal the major role of chemical bonding at the interface: premier contacts entail epitaxial integration of metal silicides with Si. Here we present epitaxially grown EuSi2/Si junction characterized by RHEED, XRD, transmission electron microscopy, magnetization and transport measurements. Structural perfection leads to superb conductivity and a record-low Schottky barrier with n-Si while an antiferromagnetic phase invites spin-related applications. This development opens brand-new opportunities in electronics. PMID:27211700

    The Stratospheric Observatory for Infrared Astronomy (SOFIA) is a Boeing 747SP carrying a 2.5 meter infrared telescope capable of operating between at altitudes of between twelve and fourteen kilometers, which is above more than 99 percent of the water vapor in the atmosphere. The ability to make observations above most water vapor coupled with the ability to make observations from anywhere, anytime, make SOFIA one of the world s premiere infrared observatories. SOFIA uses three visible light CCD imagers to assist in pointing the telescope. The data from these imagers is stored in archive files as is housekeeping data, which contains information such as boresight and area of interest locations. A tool that could both extract and process data from the archive files was developed.

  18. Distance Learning as a Tool for Poverty Reduction and Economic Development: A Focus on China and Mexico

    This paper uses case studies to focus on distance learning in developing countries as an enabler for economic development and poverty reduction. To provide perspective, we first review the history of telecottages, local technology-equipped facilities to foster community-based learning, which have evolved into "telecenters" or "Community Learning Centers" (CLCs). Second, we describe extensive site visits to CLCs in impoverished portions of China and Mexico, the centers operated by premier universities in each respective country. These CLCs constitute the core of new emerging systems of distance education, and their newness poses challenges and opportunities, which are discussed. Finally, we offer 12 points to develop further the concept and reality of distance learning in support of economic development.

    The civil rights and social legislation of the Great Society following the Civil Rights Act of 1964 was slow to provide relief for black in the South. Mississippi Senator James Eastland led an effort to defund Head Start, including his state's program, Child Development Group of Mississippi (CDGM), a program with a strong medical component. A senatorial committee, including Robert Kennedy, came to investigate CDGM in 1967. The unimaginable poverty, hunger, malnutrition and chronic disease found in black families was vehemently denied by Eastland. Visits of physician groups then corroborated the findings. The Mississippi delegation made sure that food relief never came and funding for CDGM ceased. Health services were lost to 6000 impoverished children. The epic television documentary, Hunger in America, soon premiered on network television. It triggered ongoing efforts to address health disparities, including implementation of the National Nutrition and Health Survey (NHANES). Similar physician leadership is needed to address the lasting health disparities in our country. PMID:27432045

    In June 1966, at the start of the Gulf Coast hurricane season, the Johnson Space Center (JSC) celebrated the opening of its new 4,000-square foot, state-of-the-art Emergency Operations Center (EOC). The new EOC has been upgraded and enhanced to support a wide spectrum of emergencies affecting JSC and neighboring communities. One of the main features of the EOC is its premier computerized dispatch center. The new system unites many of JSC's critical emergency functions into one integrated network. It automatically monitors fire alarms, security entrances, and external cameras. It contains the JSC inventory of hazardous materials, by building and room, and can call up Material Safety Data Sheets for most of the generic hazardous materials used on-site. The EOC is available for community use during area emergencies such as hurricanes and is a welcome addition to the Clear Lake/Galveston Bay Area communities' emergency response resources.
