    The recent outbreak of Chikungunya virus in Thailand caused a rheumatic fever associated with considerable morbidity and fatalities. Thus, it is important to identify biomarker(s) of severe disease induced by this threatening arbovirus. Putative biomarkers in cases of chikungunya fever during an outbreak in the southern part of Thailand in 2009-2010 were identified. Sixty-two patients who had developed fever and myalgia, with or without arthralgia/arthritis, were enrolled and grouped into severe chikungunya fever (CHIKF) (n= 15), mild CHIKF (n= 20) and non-CHIKF (n= 27) to investigate circulating immunological mediators that might serve as markers of severity. Blood samples were taken at presentation (day 1) and 30 days later (day 30) and plasma concentrations of interleukin (IL)-1β, IL-6, IL-8, IL-17, tumor necrosis factor-alpha, monocyte chemotactic protein-1 (MCP-1), matrix metalloproteinase-1, tissue inhibitor of matrix metalloproteinase-1 and viral load were measured by ELISA. On day 1, severe CHIKF and mild CHIKF groups had viral loads of 10(8.5) and 10(8.3) of RNA copies/mL, respectively. At presentation, all CHIKF patients had circulating concentrations of IL-6 and MCP-1 higher than did non-CHIKF patients, whereas amongst the CHKF patients, the severe CHIKF patients had higher IL-6 concentrations than did mild CHIKF patients. Interestingly, severe CHIKF patients had significantly lower concentrations of circulating IL-8 than the other groups of patients, suggesting that high concentrations of IL-6 and MCP-1 with low concentrations of IL-8 may be a determinant of severe chikungunya virus infection. © 2012 The Societies and Blackwell Publishing Asia Pty Ltd.

    Field tests were conducted near the Impact Area at Camp Edwards on the Massachusetts Military Reservation, Cape Cod, Massachusetts, to determine the utility of no-purge groundwater sampling for monitoring concentrations of ordnance-related explosive compounds and perchlorate in the sand and gravel aquifer. The no-purge methods included (1) a diffusion sampler constructed of rigid porous polyethylene, (2) a diffusion sampler constructed of regenerated-cellulose membrane, and (3) a tubular grab sampler (bailer) constructed of polyethylene film. In samples from 36 monitoring wells, concentrations of perchlorate (ClO4-), hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX), and octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine (HMX), the major contaminants of concern in the Impact Area, in the no-purge samples were compared to concentrations of these compounds in samples collected by low-flow pumped sampling with dedicated bladder pumps. The monitoring wells are constructed of 2- and 2.5-inch-diameter polyvinyl chloride pipe and have approximately 5- to 10-foot-long slotted screens. The no-purge samplers were left in place for 13-64 days to ensure that ambient groundwater flow had flushed the well screen and concentrations in the screen represented water in the adjacent formation. The sampling methods were compared first in six monitoring wells. Concentrations of ClO4-, RDX, and HMX in water samples collected by the three no-purge sampling methods and low-flow pumped sampling were in close agreement for all six monitoring wells. There is no evidence of a systematic bias in the concentration differences among the methods on the basis of type of sampling device, type of contaminant, or order in which the no-purge samplers were tested. A subsequent examination of vertical variations in concentrations of ClO4- in the 10-foot-long screens of six wells by using rigid porous polyethylene diffusion samplers indicated that concentrations in a given well varied by less than 15 percent

    We present highlights and new SMART-1 results published or obtained in 2009-2010 that are relevant for lunar science and future exploration, in relation with subsequent missions and future landers. SMART-1 is the first of ESA's Small Missions for Advanced Research and Technology [1,2,3]. Its prime objective has been achieved to demonstrate Solar Electric missions (such as Bepi-Colombo) and to test new technologies for spacecraft and instruments. The SMART-1 spacecraft was launched in 2003, as Ariane-5 auxiliary passenger, and reached on 15 March 2005 a lunar orbit 400-3000 km for a nominal science period of six months, with 1 year extension until impact on 3 September 2006. New SMART-1 lunar science and exploration results since 2009 include: - Multiangular photometry of Mare regions allowing to model scattering in planetary regoliths - The study of specific regions at different phase angles allowed to detect variations in regolith roughness - Lunar North and South polar maps and repeated high resolution images have been obtained, giving a monitoring of illumination to study potential sites relevant for future exploration. This permitted to identify SMART-1 peaks of quasi-eternal light and to derive their topography. - The SMART-1 archive observations have been used to support Kaguya, Chandrayaan-1, Chang'E 1, the US Lunar Reconnaissance Orbiter, the LCROSS impact, and to prepare subsequent landers and future human activities and lunar bases.

    The impacts of drought in the Caribbean have not been as dramatic as in some other parts of world, but it is not exempt from the experiences of drought. As a result of the effects of a prolonged drought in 2009/2010, the agenda for the 21st Inter-Sessional Meeting of the Caribbean Community (CARICOM) paid particular attention to the issue of drought. This paper reviews the management framework for responding to drought disasters in five CARICOM countries. The paper also reports on some of the effects of the 2009/2010 drought with particular reference to Grenada and the Grenadines. During the drought in these islands there were numerous bush fires with devastating effects on agriculture, severe water shortages that impacted on the tourism industry and other social effects. It is evident that there was inadequate preparation for the event. Greater planning and investment are therefore required to reduce future impacts. © 2015 The Author(s).

    2010-10-15

    Concentrating solar power can contribute significantly to the world's energy supply. As shown in this roadmap, this decade is a critical window of opportunity during which CSP could become a competitive source of electrical power to meet peak and intermediate loads in the sunniest parts of the world. This roadmap identifies technology, economy and policy goals and milestones needed to support the development and deployment of CSP, as well as ongoing advanced research in CSF. It also sets out the need for governments to implement strong, balanced policies that favour rapid technological progress, cost reductions and expanded industrial manufacturing of CSP equipment to enable mass deployment. Importantly, this roadmap also establishes a foundation for greater international collaboration. The overall aim of this roadmap is to identify actions required - on the part of all stakeholders - to accelerate CSP deployment globally. Many countries, particularly in emerging regions, are only just beginning to develop CSP. Accordingly, milestone dates should be considered as indicative of urgency, rather than as absolutes. This roadmap is a work in progress. As global CSP efforts advance and an increasing number of CSP applications are developed, new data will provide the basis for updated analysis. The IEA will continue to track the evolution of CSP technology and its impacts on markets, the power sector and regulatory environments, and will update its analysis and set additional tasks and milestones as new learning comes to light.

    The emerging technology known as concentrating solar power, or CSP, holds much promise for countries with plenty of sunshine and clear skies. Its electrical output matches well the shifting daily demand for electricity in places where airconditioning systems are spreading. When backed up by thermal storage facilities and combustible fuel, it offers utilities electricity that can be dispatched when required, enabling it to be used for base, shoulder and peak loads. Within about one to two decades, it will be able to compete with coal plants that emit high levels of CO2. The sunniest regions, such as North Africa, may be able to export surplus solar electricity to neighbouring regions, such as Europe, where demand for electricity from renewable sources is strong. In the medium-to-longer term, concentrating solar facilities can also produce hydrogen, which can be blended with natural gas, and provide low-carbon liquid fuels for transport and other end-use sectors. For CSP to claim its share of the coming energy revolution, concerted action is required over the next ten years by scientists, industry, governments, financing institutions and the public. This roadmap is intended to help drive these indispensable developments.

    associated with potential exposure to contaminated groundwater at Hanover. No drinking water wells are known to exist in Hanover, and the drinking water supply comes from RWD No.1 at Lanham, Kansas, located 6.5 mi north of Hanover. Limited potential risk was identified due to exposure to indoor air contaminated with carbon tetrachloride, but this risk has been mitigated, thereby removing this threat to human health. Radon is prevalent in the community, at concentrations exceeding the level at which the EPA recommends additional measures (testing and/or mitigation). The recommended testing and mitigation (if needed) are the responsibility of the homeowners. In the current condition in which no private wells are used for drinking water in the affected area, no unacceptable human health risk from carbon tetrachloride is associated with the identified impacted media at the Hanover site.

    We report new measurements of the elemental energy spectra and composition of galactic cosmic rays during the 2009-2010 solar minimum period using observations from the Cosmic Ray Isotope Spectrometer (CRIS) onboard the Advanced Composition Explorer. This period of time exhibited record-setting cosmic-ray intensities and very low levels of solar activity. Results are given for particles with nuclear charge 5 energy range approx. 50-550 MeV / nucleon. Several recent improvements have been made to the earlier CRIS data analysis, and therefore updates of our previous observations for the 1997-1998 solar minimum and 2001-2003 solar maximum are also given here. For most species, the reported intensities changed by less than approx. 7%, and the relative abundances changed by less than approx. 4%. Compared with the 1997-1998 solar minimum relative abundances, the 2009-2010 abundances differ by less than 2sigma, with a trend of fewer secondary species observed in the more recent time period. The new 2009-2010 data are also compared with results of a simple "leaky-box" galactic transport model combined with a spherically symmetric solar modulation model. We demonstrate that this model is able to give reasonable fits to the energy spectra and the secondary-to-primary ratios B/C and (Sc+Ti+V)/Fe. These results are also shown to be comparable to a GALPROP numerical model that includes the effects of diffusive reacceleration in the interstellar medium.

    In 2009-2010, in five points in Lublin, located in areas of different land use and built-up, measurements of air temperature and humidity were taken. Based on the data collected, the following elements were calculated: the difference in average monthly air temperature between the coldest point and the others, equivalent temperature (Tek) and Tek thermal sensations. Differences in average monthly air temperature in relation to the outskirts of Lublin were the highest at the point Dominikanie, in the built-up area of the old town. Most frequently "sultry" sensation was reported for the estate houses, at the point Ofelii. Different biothermal conditions were observed in the center of the city - Litewski square. It is characterized by a high proportion of vegetation. Green areas influenced the reduction of the biothermal stress compared to other points. The highest frequency of thermal sensation "cold", "cool" and "slightly cool" were recorded there. Measurements points located in two housing estates with high buildings close to each other were characterized by similar biothermal conditions. In these areas, comparing to other discussed areas of the city, at 12 UTC relatively often there were noticed the best biothermal conditions - "comfortable" according to equivalent temperature index

    To investigate time trends in dental service provision. A random sample of Australian dentists was surveyed by mailed questionnaires in 1983-1984, 1993-1994, 2003-2004, and 2009-2010 (response rates 67-76%). The service rate per visit was collected from a log of services. The rate of service provision per visit [rate ratio (RR)] increased from 1983-1984 to 2009-2010 for the service areas of diagnostic (RR=1.8; 1.6-1.9), preventive (RR=1.9; 1.6-2.1), endodontic (RR=2.1; 1.7-2.6), and crown and bridge (RR=2.9; 2.3-3.8), whereas prosthodontic services decreased (RR=0.7; 0.6-0.9). The profile of services provided by dentists changed over the study period to include less emphasis on replacement of teeth and more on diagnosis, prevention, and retention of natural dentitions. © 2014 FDI World Dental Federation.

    Using observations from the Cosmic Ray Isotope Spectrometer (CRIS) onboard the Advanced Composition Explorer (ACE), we present new measurements of the galactic cosmic ray (GCR) elemental composition and energy spectra for the species B through Ni in the energy range approx. 50-550 MeV/nucleon during the record setting 2009-2010 solar minimum period. These data are compared with our observations from the 1997-1998 solar minimum period, when solar modulation in the heliosphere was somewhat higher. For these species, we find that the intensities during the 2009-2010 solar minimum were approx. 20% higher than those in the previous solar minimum, and in fact were the highest GCR intensities recorded during the space age. Relative abundances for these species during the two solar minimum periods differed by small but statistically significant amounts, which are attributed to the combination of spectral shape differences between primary and secondary GCRs in the interstellar medium and differences between the levels of solar modulation in the two solar minima. We also present the secondary-to-primary ratios B/C and (Sc+Ti+V)/Fe for both solar minimum periods, and demonstrate that these ratios are reasonably well fit by a simple "leaky-box" galactic transport model that is combined with a spherically symmetric solar modulation model.

    Recent injury-surveillance data for collegiate-level women's gymnastics are limited. In addition, researchers have not captured non-time-loss injuries (ie, injuries resulting in restriction of participation gymnastics injuries during the 2009-2010 through 2013-2014 academic years. Descriptive epidemiology study. Aggregate injury and exposure data collected from 11 women's gymnastics programs providing 28 seasons of data. Collegiate student-athletes participating in women's gymnastics during the 2009-2010 through 2013-2014 academic years. Women's gymnastics data from the NCAA Injury Surveillance Program (ISP) during the 2009-2010 through 2013-2014 academic years were analyzed. Injury rates; injury rate ratios; injury proportions by body site, diagnosis, and apparatus; and injury proportion ratios were reported with 95% confidence intervals (CIs). The ISP captured 418 women's gymnastics injuries, a rate of 9.22/1000 athlete-exposures (AEs; 95% CI = 8.33, 10.10). The competition injury rate (14.49/1000 AEs) was 1.67 times the practice injury rate (8.69/1000 AEs; 95% CI = 1.27, 2.19). When considering time-loss injuries only, the injury rate during this study period (3.62/1000 AEs) was lower than rates reported in earlier NCAA ISP surveillance data. Commonly injured body sites were the ankle (17.9%, n = 75), lower leg/Achilles tendon (13.6%, n = 57), trunk (13.4%, n = 56), and foot (12.4%, n = 52). Common diagnoses were ligament sprain (20.3%, n = 85) and muscle/tendon strain (18.7%, n = 78). Overall, 12.4% (n = 52) of injuries resulted in time loss of more than 3 weeks. Of the 291 injuries reported while a student-athlete used an apparatus (69.6%), most occurred during the floor exercise (41.9%, n = 122) and on the uneven bars (28.2%, n = 82). We observed a lower time-loss injury rate for women's gymnastics than shown in earlier NCAA ISP surveillance data.

    The sedimentation of HNO3 containing Polar Stratospheric Cloud (PSC) particles leads to a permanent removal of HNO3 and thus to a denitrification of the stratosphere, an effect which plays an important role in stratospheric ozone depletion. The polar vortex in the Arctic winter 2009/2010 was very cold and stable between end of December and end of January. Strong denitrification between 475 to 525 K was observed in the Arctic in mid of January by the Odin Sub Millimetre Radiometer (Odin/SMR). This was the strongest denitrification that had been observed in the entire Odin/SMR measuring period (2001-2010). Lidar measurements of PSCs were performed in the area of Kiruna, Northern Sweden with the IRF (Institutet för Rymdfysik) lidar and with the Esrange lidar in January 2010. The measurements show that PSCs were present over the area of Kiruna during the entire period of observations. The formation of PSCs during the Arctic winter 2009/2010 is investigated using a microphysical box model. Box model simulations are performed along air parcel trajectories calculated six days backward according to the PSC measurements with the ground-based lidar in the Kiruna area. From the temperature history of the backward trajectories and the box model simulations we find two PSC regions, one over Kiruna according to the measurements made in Kiruna and one north of Scandinavia which is much colder, reaching also temperatures below Tice. Using the box model simulations along backward trajectories together with the observations of Odin/SMR, Aura/MLS (Microwave Limb Sounder), CALIPSO (Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations) and the ground-based lidar we investigate how and by which type of PSC particles the denitrification that was observed during the Arctic winter 2009/2010 was caused. From our analysis we find that due to an unusually strong synoptic cooling event in mid January, ice particle formation on NAT may be a possible formation mechanism during

    Full Text Available The aims of this study are twofold. First, this research aims to detect the extent to which Croatian politicians strategically use information from the private sphere in public discourse; second, to detect the functions in which this information is used. I analyze the mediated statements in the main national daily newspapers of the two main presidential candidates in the 2009-2010 elections. I start with the premise that the macro (elements of political and media system and micro (candidates’ personalities contextual factors of this elections were favorable to privatization of politics. The results show that a significant extent of the public discourse was indeed privatized, but mostly due to the communication strategy of Milan Bandić. Furthermore, the results demonstrate that the information from the private sphere was not used solely for the purpose of building one’s image, but also as a strategy of attacking the opponent.

    This working report presents the first results of a sampling campaign at Olkiluoto and reference lakes and rivers selected to resemble the aquatic systems expected to form at the site in the future with the post-glacial crustal rebound (land uplift). In 2009-2010, the aim of the studies was to improve the knowledge of the aquatic systems and to produce input data to the safety case for the spent nuclear fuel repository at Olkiluoto. The first main objective was to estimate the areal biomass distribution and measure the dimensions of characteristic aquatic plants and animals. Another objective was to estimate the transfer of different elements from water to the aquatic organisms paying special attention on key elements (Ag, Cl, I, Mo, Nb and Se) in the dose assessment within the safety case. Surface water, sediment, macrophyte, fish and macrobenthos samples were collected from the Olkiluoto coastal area and from the reference lakes for biomass and dimension measurements and analysis of element concentration. Water-to-biota concentration ratios were estimated for the coastal area and for the reference lakes. From rivers, only water samples were collected at this stage. In 2009-2010, sampling procedures and pre-treatment methods were developed and analytical methods were optimised. Thus, the results reported here are indicative by their nature. After 2010, the studies have been continued with better established methods, and the more recent results will be reported later. (orig.)

    Smoking during pregnancy may cause many health problems for pregnant women and their newborns. However, there is a paucity of research that has examined the predictors of smoking during pregnancy in Canada. This study used data from the 2009-2010 Canadian Community Health Survey (CCHS) to estimate the prevalence of smoking during pregnancy and examine the demographic, socioeconomic, health-related and behavioral determinants of this behavior. The data were obtained from the 2009-2010 CCHS master data file. Weighted estimates of the prevalence were calculated. Multivariable logistic regression was used to determine demographic, socioeconomic, health related and behavioral characteristics associated with smoking behavior during pregnancy. Women living in the Northern Territories had a high rate of smoking during pregnancy (59.3%). The prevalence of smoking during pregnancy was also high among women under 25 years old, of low socioeconomic status, who reported not having a regular medical doctor, being fair to poor in self-perceived health, having at least one chronic disease, having at least one mental illness, being heavy smokers, and being regular alcohol drinkers. Results from multivariable logistic regression revealed that the odds of smoking during pregnancy were decreased with increasing age (odds ratio [OR], 0.95; 95% confidence interval [CI], 0.91-0.99), having a regular family doctor [OR, 0.24; 95% CI, 0.11-0.52], having highest level of family income [OR, 0.09; 95% CI, 0.03-0.29]. Mothers who reported poor or fair self-perceived health [OR, 2.13; 95% CI, 0.96-4.71] and those who had at least one mental illness [OR, 1.81; 95% CI, 1.00-3.28] had greater odds of smoking during pregnancy. There are a number of demographic, socio-economic, health-related and behavioral characteristics that should be considered in developing and implementing effective population health promotional strategies to prevent smoking during pregnancy, promoting health and well-being of

A number of sensitivity runs is used to explore the impact of uncertainties in chlorine activation and denitrification on the model results. In particular, the efficiency of chlorine activation on different types of liquid aerosol versus activation on nitric acid trihydrate clouds is examined. Additionally, the impact of changes in reaction rate coefficients, in the particle number density of polar stratospheric clouds, in supersaturation, temperature or the extent of denitrification is investigated. Results are compared to satellite measurements of MLS and ACE-FTS and to in-situ measurements onboard the Geophysica aircraft during the RECONCILE measurement campaign. It is shown that even large changes in the underlying assumptions have only a small impact on the modeled ozone loss, even though they can cause considerable differences in chemical evolution and denitrification. In addition, it is shown that chlorine activation on liquid aerosols alone is able to explain the observed magnitude and morphology of the mixing ratios of active chlorine, reservoir gases and ozone.

    To compare the unprecedented 91 cases of melioidosis in the Top End of the Northern Territory of Australia from 1 October 2009 to 30 September 2010 with the 540 cases in the preceding 20 years and postulate reasons for this year of very high melioidosis incidence. Review of prospectively collected data on all patients with culture-confirmed melioidosis at Royal Darwin Hospital, the Top End's tertiary referral centre, since 1 October 1989. Population-based annual incidence of melioidosis; differences in epidemiology, clinical presentations and outcomes for 2009-2010 compared with the preceding 20 years. In 2009-2010, the estimated population-based incidence of melioidosis was 50.2 cases per 100 000 in the Top End population overall, and 102.4 cases per 100 000 in the Top End Indigenous population. The proportion of patients acquiring melioidosis in the Darwin urban area increased from 49% in 1989-2009 to 65% in 2009-2010 (OR, 1.96; 95% CI, 1.20-3.19). Among the 49 Indigenous Australian patients with melioidosis in 2009-2010, 63% acquired the infection in Darwin, compared with 35% of Indigenous patients in the previous 20 years (OR, 3.17; 95% CI, 1.62-6.24). In 2009-2010, the Top End had the highest annual incidence of melioidosis documented from anywhere to date. The prominent increase in cases in Darwin was associated with above average rainfall in Darwin during December 2009 to February 2010. The increase in the proportion of Indigenous Australians who acquired melioidosis in Darwin may reflect movement of some Indigenous people into Darwin from remote communities.

This research aims to compare the expression of football teams tactics, with different levels ofperformance, defined on the basis of placement on the table, after a competitive season. More precisely, it isnecessary to determine whether and to what extent there are differences in the implementation of certain tacticalassets (features in the organization of successful attacks, among teams that are placed differently on the table.Methods. In the tactical analysis of expression of 12 teams divided into 3 groups based on placement on thetable a total of 228 games in the 2009/2010 Super League in Serbia were covered. The first group (G1 consistedof the teams that took the top four place in the standings, the second group (G2 teams that were placed from 7thto 11th place and a third group (G3 consisted of four last placed teams. Observed parameters are related to theefficiency of pass games and the structure of successful attacks, attacks that have been completed by a shot to thegoal. All observed parameters were conducted with specially made software, which is used to analyse footballgames.Results. By analysing the frequency of successful attacks, it was found that there is a statistically significantdifference in the number of successful attacks among the teams that are placed differently on the table (p =0.001, in favor of the better placed team. Also, the success of the attack, seen through their precision indicatesthe differences in their distribution (p = 0.025 among these groups. The results further suggest that the structureof attack is not related to the placement of the teams in the standings. However, the success of passing proved tobe an important factor in achieving a better placement (p = 0.004, and the distance from which kick is directedat goal (p = 0.021.Conclusion. The results of this study may help to identify those tactic features in football, which contribute toachieving better results.

    Lawrence Livermore National Laboratory (LLNL) requested that Condor Country Consulting, Inc. (CCCI) perform wet season surveys and manage the dry season sampling for listed branchiopods in two ponded locations within the Site 300 Experimental Test Site. Site 300 is located in Alameda and San Joaquin Counties, located between the Cities of Livermore and Tracy. The two pool locations have been identified for possible amphibian enhancement activities in support of the Compensation Plan for impacts tied to the Building 850 soil clean-up project. The Building 850 project design resulted in formal consultation with the U.S. Fish and Wildlife Service (USFWS) as an amendment (File 81420-2009-F-0235) to the site-wide Biological Opinion (BO) (File 1-1-02-F-0062) in the spring of 2009 and requires mitigation for the California tiger salamander (AMCA, Ambystoma californiense) and California red-legged frog (CRLF, Rana draytonii) habitat loss. Both pools contain breeding AMCA, but do not produce metamorphs due to limited hydroperiod. The pool to the southeast (Pool BC-FS-2) is the preferred site for amphibian enhancement activities, and the wetland to northwest (Pool OA-FS-1) is the alternate location for enhancement. However, prior to enhancement, LLNL has been directed by USFWS (BO Conservation Measure 17 iii) to 'conduct USFWS protocol-level branchiopod surveys to determine whether listed brachiopod species are present within the compensation area.' CCCI conducted surveys for listed branchiopods in the 2009-2010 wet season to determine the presence of federally-listed branchiopods at the two pools (previous surveys with negative findings were performed by CCCI in 2001-2002 and 2002-2003 onsite). Surveys were conducted to partially satisfy the survey requirements of the USFWS 'Interim Survey Guidelines to Permittees for Recovery Permits under Section 10(a)(1)(A) of the Endangered Species Act for the Listed Vernal Pool Branchiopods' ('Guidelines, USFWS

    Full Text Available Swine influenza (SI is caused by the type A swine influenza virus (SIV. It is a highly contagious disease with a rapid course and recovery. The major clinical signs and symptoms are cough, fever, anorexia and poor performance. The disease has been associated with other co-infections in many countries, but not in Brazil, where, however, the first outbreak has been reported in 2011. The main aim of this study was to characterize the histological features in association with the immunohistochemical (IHC results for influenza A (IA, porcine circovirus type 2 (PCV2 and porcine reproductive and respiratory syndrome virus (PRRSV in lung samples from 60 pigs submitted to Setor de Patologia Veterinária at the Universidade Federal do Rio Grande do Sul (SPV-UFRGS, Brazil, during 2009-2010. All of these lung samples had changes characterized by interstitial pneumonia with necrotizing bronchiolitis, never observed previously in the evaluation of swine lungs in our laboratory routine. Pigs in this study had showed clinical signs of a respiratory infection. Swine samples originated from Rio Grande do Sul 31 (52%, Santa Catarina 14 (23%, Paraná 11 (18%, and Mato Grosso do Sul 4 (7%. Positive anti-IA IHC labelling was observed in 45% of the cases, which were associated with necrotizing bronchiolitis, atelectasis, purulent bronchopneumonia and hyperemia. Moreover, type II pneumocyte hyperplasia, alveolar and bronchiolar polyp-like structures, bronchus-associated lymphoid tissue (BALT hyperplasia and pleuritis were the significant features in negative anti-IA IHC, which were also associated with chronic lesions. There were only two cases with positive anti-PCV2 IHC and none to PRRSV. Therefore, SIV was the predominant infectious agent in the lung samples studied. The viral antigen is often absent due to the rapid progress of SI, which may explain the negative IHC results for IA (55%; therefore, IHC should be performed at the beginning of the disease.

    To report on coverage and adequacy of health insurance for children with special health care needs (CSHCN) in 2009-2010 and assess changes since 2001. Data were from the National Survey of Children with Special Health Care Needs (NS-CSHCN), a random-digit telephone survey with 40,243 (2009-2010) and 38,866 (2001) completed interviews. Consistency and adequacy of insurance was measured by: 1) coverage status, 2) gaps in coverage, 3) coverage of needed services, 4) reasonableness of uncovered costs, and 5) ability to see needed providers, as reported by parents. Bivariate and multivariable analyses were conducted to assess factors associated with adequate insurance coverage in 2009-2010. Unadjusted and adjusted prevalence estimates were examined to identify changes in the type of insurance coverage and the proportion of CSHCN with adequate coverage by insurance type. The proportion of CSHCN with private coverage decreased from 64.7% to 50.7% between 2001 and 2009-2010, while public coverage increased from 21.7% to 34.7%; the proportion of CSHCN without any insurance declined from 5.2% to 3.5%. The proportion of CSHCN with adequate coverage varied over time and by insurance type: among privately covered CSHCN, the proportion with adequate coverage declined (62.6% to 59.6%), while among publicly covered CSHCN, the proportion with adequate insurance increased (63.0% to 70.7%). Publicly insured CSHCN experienced improvements in each of the 3 adequacy components. There has been a continued shift from private to public coverage, which is more affordable, offers benefits that are more likely to meet CSHCN needs, and allowed CSHCN to see necessary providers.

    [Objective] To understand the epidemiological characteristics of measles in Xi County of Henan Province from 2009-2010, and explore the strategy for its control and elimination. [Methods] Descriptive epidemiological analysis was performed on the measles cases reported by measles surveillance system from 2009-2010. [Results] Measles cases were reported in 90% villages and towns of Xi County, the reported incidence in 2009 and 2010 was 11.31/100 000 and 1.18/100 000, without death cases. The incidence in 2009 increased significantly compared with that in 2007 and 2008, most cases appeared in spring, with peak incidence in April. The infants < 8 months had the maximum of measles cases among age groups from 2009-2010, 59.54% were children under 3 years old. The ratio of male to female was 2.20:1, the 2-years-ld accounted for 80.85% of cases without immunization history. The reported vaccination rate of township school-age children was above 95% during the campaign of MMR vaccine e-mergency vaccination in March 2010. The incidence of measles was controlled well and it decreased to a low level in 2010. [Conclusion] The measles patients constitution has changed (the small -month-old groups and older age groups) which relates with immunization gaps, fetal transfer of antibodies insufficient and nosocomial infections. The enhancement of measles vaccination a-mong school-age children and focus groups, improvement of vaccination rates and quality of measles surveillance, and strict nosocomial infections control are the main measures for measles control.%目的 了解河南省息县2009-2010年麻疹流行病学特征,探讨控制和消除麻疹策略.方法 对息县2009-2010年麻疹监测系统报告的麻疹病例进行描述流行病学分析.结果 息县有90%的乡镇有麻疹病例报告,2009年报告发病率11.31/10万,2010年发病率1.18/10万,无病例死亡.2009年较2007年、2008年有明显上升,春季高发,4月份达到高峰.2009-2010年<8

    Full Text Available Droughts are projected to increase in severity and frequency on both regional and global scales. Despite the increasing occurrence and intensity of the 2009/2010 drought in southwestern China, the impacts of drought on vegetation in this region remain unclear. We examined the impacts of the 2009/2010 drought in southwestern China on vegetation by calculating the standardized anomalies of Normalized Difference Vegetation Index (NDVI, Enhanced Vegetation Index (EVI, Normalized Difference Water Index (NDWI, and Land Surface Temperature (LST. The standardized anomalies of NDVI, EVI, and NDWI exhibited positively skewed frequency distributions, while the standardized anomalies of LST exhibited a negatively skewed frequency distribution. These results implied that the NDVI, EVI, and NDWI declined, while LST increased in the 2009/2010 drought-stricken vegetated areas during the drought period. The responses of vegetation to the 2009/2010 drought differed substantially among biomes. Savannas, croplands, and mixed forests were more vulnerable to the 2009/2010 drought than deciduous forest and grasslands, while evergreen forest was resistant to the 2009/2010 drought in southwestern China. We concluded that the 2009/2010 drought had negative impacts on vegetation in southwestern China. The resulting assessment on the impacts of drought assists in evaluating and mitigating its adverse effects in southwestern China.

    Background In the Nordic countries, substantial policy and intervention efforts have been made to increase adolescents' consumption of fruit and vegetables and to reduce their intake of sweets and soft drinks. Some initiatives have been formulated in a Nordic collaboration and implemented at national level. In recent years, social inequalities in food habits have been attracted particular governmental interest and several initiatives addressing the socioeconomic gradient in food habits have been highlighted. However, few internationally published studies have evaluated how trends in adolescents' food habits develop in the context of Nordic nutrition policy, or have compared differences between the Nordic countries. Methods The study was based on Danish, Finnish, Norwegian and Swedish cross-sectional data from the international Health Behaviour in School-Aged Children (HBSC) study, collected via three nationally representative and comparable questionnaire surveys in 2001/2002, 2005/2006 and 2009/2010. Food habits were identified by students' consumption of fruit, vegetables, sweets and sugar sweetened soft drink. Socioeconomic status (SES) was measured with the Family Affluence Scale (FAS). Multilevel logistic regression was used to analyze the data. Results Trends in fruit consumption developed differently across countries, characterized by an increase in Denmark and Norway and more stable trends in Sweden and Finland. Vegetable consumption increased particularly in Denmark and to a lesser extent in Norway, whereas Sweden and Finland displayed stable trends. Decreased trends were observed for sweet and soft drink consumption and were similar in Norway, Sweden and Finland. Sweet consumption decreased across all survey years, whereas soft drink consumption decreased between 2001/2002–2005/2006 and was stable thereafter. Denmark displayed an increase between 2001/2002–2005/2006 followed by a similar decrease between 2005/2006–2009/2010 for both sweet and soft

    To understand the mechanisms responsible for the severe drought in Yunnan Province during the boreal winter (DJF) of 2009/2010, by using NCEP/NCAR reanalysis data and winter precipitation index in Yunnan Province which is calculated from station precipitation data in Yunnan Province, this study investigates the relationship between the North Atlantic Oscillation (NAO) and the precipitation in Yunnan Province during boreal winters. In the 49 winters of 1961/1961 - 2009/2010 period, the correlation coefficient between the time series of winter mean precipitation indices in Yunnan Province and the NAO indices is 0. 373 (exceeds the 95% confidence level), which indicates that the winter precipitation in Yunnan Province is linked to the variability of the NAO. Regression resultsbetween the winter precipitation indices in Yunnan Province and the northern hemispheric anomalous geopotential height at 300 hPa show that the circulation systems associated with the winter precipitation in Yunnan Province have a south and a north major components: the southern branch trough and the ridge of Lake Baikal. And the results show that the NAO can impact these two components through the quasi-stationary waves propagating along the Asia- Africa subtropical jet and the wave reflections, respectively. Therefore, the variations of the NAO and the winter precipitation in Yunnan Province are linked. The results also show that the linkage between the NAO and the winter precipitation in Yunnan Province is modulated by ENSO phenomenon. The relationship between the NAO and the winter precipitation in Yunnan Province is much close in the warm ENSO winters, while, they are barely linked in the cold ENSO winters.%为了揭示2009/2010年冬季云南出现严重干旱灾害的原因,本文利用NCEP/NCAR再分析资料以及云南省台站降水资料计算得到的云南冬季降水指数,讨论了在北半球冬季(12~2月)北大西洋涛动(North Atlantic Oscillation,简称NAO)和云南省降

    The aim of this study was to determine influenza vaccine coverage among children aged 0-18 years in inner city practices in Poland in the 2009/2010 season and factors that might have influenced low vaccination coverage. A retrospective review of 11,735 vaccination charts of children aged 0-18 from seven randomly selected general practices in the capital city of Warsaw and one large practice in the city of Wroclaw was performed. We calculated the numbers of children who were vaccinated in the 2009/2010 season and analyzed the age distribution of vaccinated children. We also reviewed the vaccination history in patients who were vaccinated against influenza including: previous influenza vaccinations, modification (widening) of standard immunization scheme, and a proportion of children who completed the recommended two-dose schedule of vaccination. In the calculations, 95% confidence intervals were used. Out of the total of 11,735 children surveyed, 362 (3.1%, CI: 2.8-3.4%) were vaccinated against influenza in the 2009/2010 season. For 115 of these 362 (31.8%, CI: 27.0-36.6%) children it was their first vaccination against influenza. The mean age of a vaccinated child was 6.0 ± 4.3 years. Children aged 2-5 were most commonly vaccinated (153/362, 42.3%, CI: 37.2-47.4%), while infants (aged 6-12 months) were vaccinated rarely (15/362, 4.4%, CI: 2.2-6.2%). In the group of children younger than 8 years (86/362 children) who were vaccinated for the first time in their life only 29/86 (33.7%, CI: 23.7-43.7%) completed the recommended two-dose schedule. In conclusion, the importance of vaccinating children against influenza is hugely understated in Poland. General physicians should actively recommend annual influenza immunization of children. Recommendations of National Immunization Program concerning influenza vaccine should be clearer, simpler, and easier to implement.

    Mt Garet, on Gaua Island, is one of the active volcanoes of the Vanuatu arc. We report here a new dataset on lapilli and lava erupted during Mt Garet unrest in 2009-2010 and on products of the older activity of Gaua composite volcano. The present-day magma of Mt Garet is a trachy-andesite (52 wt.% SiO2) with relatively high Rb/Th (14.6) and Ba/La (41) ratios compared to the Gaua pre- and syn-caldera series, but typical of the central part of Vanuatu arc. Its mineral assemblage is mainly composed of plagioclase (An86-56) and clinopyroxene (Fs5-16) which display significant chemical variations, patchy zones, surface dissolution, and oscillatory zoning that imply episodes of high undercooling and growth rates. The paragenesis is complemented by Fe-Ti oxides and scarce olivine (Fo72-73). The melt inclusions are ubiquitous and their compositions cover a chemical spectrum from basalt to trachy-andesite. Volatile-rich basaltic inclusions (H2O: 2.7 wt.%, S: 0.15 wt.%, and Cl: 0.22 wt.%) are preserved in Mg-rich clinopyroxene whereas the majority of the melt inclusions is volatile poorer with, ≤ 1.0 wt.% of H2O, ≤ 0.05 wt.% of S, and 0.25-0.27 wt.% of Cl. At 1100 °C the measured viscosity of anhydrous magma of Mt Garet is 103.5 Pa s. Adding 0.8 to 2.5 wt.% of H2O decreases the melt viscosity by 0.5 to two orders of magnitude. Combining data on bulk rocks, minerals, and their melt inclusions together with the very first published gas fluxes acquired during the same period of activity, we propose that the high sulfur outgassing in 2009-2010 was produced by the degassing of a basaltic magma batch ( 0.027 km3) emplaced in a shallow reservoir. This scenario would require temperature and H2O-loss driven resorption/crystallization, magma mixing, and exsolution of an early gas phase rich in H2O, and S. We suggest here the 2009-2010 activity to be sustained by the existence of thermal convection driven at the bottom of the magma reservoir by cooling, and in which the bubbles

    Pesticides are among the most widely used chemicals in the world. Because of the widespread use of agricultural chemicals in food production, people are exposed to low levels of pesticide residues through their diets. Scientists do not yet have a total understanding of the health effects of these pesticide residues. This work aims to determine differences in terms of pesticide residue content in Portuguese strawberries grown using different agriculture practices. The Quick, Easy, Cheap, Effective, Rugged, and Safe sample preparation method was conducted and shown to have good performance for multiclass pesticides extraction in strawberries. The screening of 25 pesticides residue was performed by gas chromatography-tandem mass spectrometry. In quantitative validation, acceptable performances were achieved with recoveries of 70-120 and integrated pest management (IPM) practices harvested in 2009-2010. The results showed the presence of fludioxonil, bifenthrin, mepanipyrim, tolylfluanid, cyprodinil, tetraconazole, and malathion when using IPM below the maximum residue levels.

    Outbreaks of serious infections associated with heroin use in persons who inject drugs (PWIDs) occur intermittently and require vigilance and rapid reporting of individual cases. Here, we give a firsthand account of the cases in London during an outbreak of heroin-associated anthrax during 2009-2010 in the United Kingdom. This new manifestation of anthrax has resulted in a clinical manifestation distinct from already recognized forms. During 2012-13, additional cases of heroin-associated anthrax among PWIDs in England and other European countries were reported, suggesting that anthrax-contaminated heroin remains in circulation. Antibacterial drugs used for serious soft tissue infection are effective against anthrax, which may lead to substantial underrecognition of this novel illness. The outbreak in London provides a strong case for ongoing vigilance and the use of serologic testing in diagnosis and serologic surveillance schemes to determine and monitor the prevalence of anthrax exposure in the PWID community.

    Since 2000, a sentinel surveillance of influenza, INFLUNET, exists in Italy. It is coordinated by the Ministry of Health and is divided into two parts; one of these is coordinated by the National Institute of Health (NIH), the other by the Inter-University Centre for Research on Influenza and other Transmissible Infections (CIRI-IT). The influenza surveillance system performs its activity from the 42nd week of each year (mid-October) to the 17th week of the following year (late April). Only during the pandemic season (2009/2010) did surveillance continue uninterruptedly. Sentinel physicians - about 1,200 general practitioners and independent pediatricians - send in weekly reports of cases of influenza-like illness (ILI) among their patients (over 2% of the population of Italy) to these centers.   In order to estimate the burden of pandemic and seasonal influenza, we examined the epidemiological data collected over the last 3 seasons (2009-2012). On the basis of the incidences of ILIs at different ages, we estimated that: 4,882,415; 5,519,917; and 4,660,601 cases occurred in Italy in 2009-2010, 2010-2011 and 2011-2012, respectively. Considering the ILIs, the most part of cases occurred in < 14 y old subjects and especially in 5-14 y old individuals, about 30% and 21% of cases respectively during 2009-2010 and 2010-2011 influenza seasons. In 2011-2012, our evaluation was of about 4.7 million of cases, and as in the previous season, the peak of cases regarded subjects < 14 y (about 29%). A/California/07/09 predominated in 2009-2010 and continued to circulate in 2010-2011. During 2010-2011 B/Brisbane/60/08 like viruses circulated and A/H3N2 influenza type was sporadically present. H3N2 (A/Perth/16/2009 and A/Victoria/361/2011) was the predominant influenza type-A virus that caused illness in the 2011-2012 season. Many strains of influenza viruses were present in the epidemiological scenario in 2009-2012. In the period 2009-2012, overall vaccination coverage was low

    Diabetes mellitus (DM) is a recognized atherosclerotic cardiovascular disease (ACVD) risk factor. This association has yet to be quantified in the Chilean population. To compare the frequency of ACVD between diabetic and non-diabetic Chilean subjects. Data was extracted from the Chile National Health Survey (ENS) performed in 2009-2010. DM diagnosis was made with fasting glucose. ACVD (coronary, cerebral and peripheral vascular disease) was established by self-report. Major cardiovascular risk factors were identified by clinical and laboratory assessment. A total of 5,416 adults (2,200 men and 3,216 women) were surveyed in ENS 2009-2010. Of these, 508 were diabetic and 375 reported ACVD. ACVD frequency was 16.1% and 6.1% in diabetic and non-diabetic subjects, respectively. In diabetic men, the frequency of ACVD steadily increased with age, from 5.1% to 22.1%. In diabetic women, the highest frequency of ACVD (17.4%) was found in ages ranging from 45 to 54 years. In people younger than 54 years, the odds ratio for ACVD in diabetic compared to non-diabetic subjects, was 3.59 in men (χ2 = 4.03 p < 0.03) and 5.26 in women (χ2 = 7.7 p < 0.007). Cardiovascular risk factors and metabolic syndrome were significantly more common in diabetic subjects with reported ACVD. DM is associated with an increased frequency of ACVD and cardiovascular risk factors in Chilean adults. In line with international reports, our findings suggest that DM is also a cardiovascular risk factor in Chile, particularly relevant for women.

    2009/2010年冬季出现了持续的北极涛动(AO)负异常,同时北半球的天气气候也发生了大范围的异常,两者的关系是大家极为关注的重要问题.本文的分析表明2009/2010年冬季北半球经历了两次显著的AO负异常过程,2009年12月和2010年2月AO指数分别达到了同期历史的最低值.2009年12月的AO负异常过程又可以又分为两个阶段,第一个阶段是由于前期行星波上传的增强导致平流层极涡减弱,随后平流层环流异常向下发展造成了对流层的AO负异常;第二个阶段是因为对流层低层高纬地区的温度正异常维持了第一个阶段在对流层高纬地区的位势高度正异常,使得AO负异常得以较长时间维持,这两个阶段的接连发生和共同作用使得对流层低层经历了一个较强的AO负异常过程.而2010年2月的AO负异常过程则是由平流层爆发性增温所造成的平流层异常环流下传造成的.通过对历史上11个AO负异常事件的统计分析,可以认为AO负异常事件可能由平流层爆发性增温以及平流层极区弱的环流异常下传造成,也可能来源于对流层内部的动力过程.进一步研究表明,2009/2010年冬季持续的极端AO负异常与该冬季北半球大范围的温度和降水异常有密切联系,关注AO异常及其影响是天气预报、气候预测的重要问题.

    Full Text Available The CRISTA-NF (Cryogenic Infrared Spectrometers and Telescope for the Atmosphere – New Frontiers instrument is an airborne infrared limb sounder operated aboard the Russian research aircraft M55-Geophysica. The instrument successfully participated in a large Arctic aircraft campaign within the RECONCILE (Reconciliation of essential process parameters for an enhanced predictability of Arctic stratospheric ozone loss and its climate interactions project from January to March 2010 in Kiruna, Sweden. This paper concentrates on the measurements during one flight of the campaign, which took place on 2 March in the vicinity of the polar vortex. We present two-dimensional cross-sections of volume mixing ratios for the trace gases CFC-11, O3, and ClONO2 with an unprecedented vertical resolution of about 500 to 600 m for a large part of the observed altitude range and a dense horizontal sampling along flight direction of ≈ 15 km. The trace gas distributions show several structures like the polar vortex and filaments composed of air masses of different origin. The situation during the analysed flight is simulated by the chemistry and transport model CLaMS (Chemical Lagrangian Model of the Stratosphere and compared with the measurements to assess the performance of the model with respect to advection, mixing, and the chemistry in the polar vortex. These comparisons confirm the capability of CLaMS to reproduce even very small-scale structures in the atmosphere. Based on the good agreement between simulation and observation, we use a model concept utilising artificial tracers to further analyse the CRISTA-NF observations in terms of air mass origin. A characteristic of the Arctic winter 2009/10 was a sudden stratospheric warming in early December that led to a split of the polar vortex. The vortex re-established at the end of December. Our passive tracer simulations suggest that large parts of the re-established vortex consisted to about 45% of high- and

    On December 22, 2008, a dike containing fly ash and bottom ash at the Tennessee Valley Authority's (TVA) Kingston Fossil Plant in East Tennessee failed and released a large quantity of ash into the adjacent Emory River. Ash deposits from the spill extended 4 miles upstream of the facility to Emory River mile 6 and downstream to Tennessee River mile 564 ({approx}8.5 miles downstream of the confluence of the Emory River with the Clinch River, and {approx}4 miles downstream of the confluence of the Clinch River with the Tennessee River). A byproduct of coal combustion, fly ash contains a variety of metals and other elements which, at sufficient concentrations and in specific forms, can be harmful to biological systems. The ecological effects of fly ash contamination on exposed fish populations depend on the magnitude and duration of exposure, with the most significant risk considered to come from elevated levels of certain metals in the ash, particularly selenium, on fish reproduction and fish early life stages (Lemly 1993; Besser and others 1996). The ovaries of adult female fish in a lake contaminated by coal ash were reported to have an increased frequency of atretic oocytes (dead or damaged immature eggs) and reductions in the overall numbers of developing oocytes (Sorensen 1988) associated with elevated body burdens of selenium. Larval fish exposed to selenium through maternal transfer of contaminants to developing eggs in either contaminated bodies of water (Lemly 1999) or in experimental laboratory exposures (Woock and others 1987, Jezierska and others 2009) have significantly increased incidences of developmental abnormalities. Contact of fertilized eggs and developing embryos to ash in water and sediments may also pose an additional risk to the early life stages of exposed fish populations through direct uptake of metals and other ash constituents (Jezierska and others 2009). The establishment and maintenance of fish populations is intimately associated

    The continuous and precise data were recorded by variety precursor instruments in the Hubei Local-Earthquake-precursor Observing System during the 2009 -2010 solar eclipse. After the careful processing and analysis for observations, three significant variations all related to the solar eclipse are found. Firstly, the geomagnetic anomaly valleys appeared before the eclipse starting. Secondly, during the total and annular solar eclipse, there were some differences between geomagnetic components and between micro-changing geomagnetic anomaly phenomena. Before and after the total solar eclipse, there were clear features with short-time and synchronization on the geomagnetic horizontal component. However, during the annular solar eclipse, geomagnetic declination component shows transition-type change characteristics with trended and lagged. Thirdly, the solar eclipse made the tilt and strain of crustal deformation observations short-time pulsate.%对2009-2010年两次日食活动期间的湖北省区域地震前兆原始观测数据进行分析,结果显示日食效应对某些前兆测项有一定影响,具体表现为:1)地磁观测到达低值时间出现于日全食开始前;2)2009年7月22日日全食和2010年1月15日日环食期间地磁观测测项分量、扰动形态变化特征不尽相同.日全食前后地磁场变化主要表现为地磁水平分量H向下跃动的起伏型变化,具有短时、较为同步的特点;而日环食发生时,地磁场的变化主要表现为地磁偏角D的趋势转折,具有趋势变化、滞后性的特点;3)日食活动对地壳形变中的固体潮线应变和倾斜量也产生短时扰动.

    Comparisons are presented of point-focusing, or 'dish' solar concentrator system features, development status, and performance levels demonstrated to date. In addition to the requirements of good optical efficiency and high geometric concentration ratios, the most important future consideration in solar thermal energy dish concentrator design will be the reduction of installed and lifetime costs, as well as the materials and labor costs of production. It is determined that technology development initiatives are needed in such areas as optical materials, design wind speeds and wind loads, structural configuration and materials resistance to prolonged exposure, and the maintenance of optical surfaces. The testing of complete concentrator systems, with energy-converting receivers and controls, is also necessary. Both reflector and Fresnel lens concentrator systems are considered.

    Information about infectious disease outbreaks is often gathered indirectly, from doctor's reports and health board records. It also typically underestimates the actual number of cases, but the relationship between the observed proxies and the numbers that drive the diseases is complicated, nonlinear and potentially time- and state-dependent. We use a combination of data collection from the 2009-2010 H1N1 outbreak in Malta, compartmental modelling and Bayesian inference to explore the effect of using various sources of information (consultations, doctor's diagnose, swabbing and molecular testing) on estimation of the effective basic reproduction ratio, R(t). Different proxies and different sampling rates (daily and weekly) lead to similar behaviour of R(t) as the epidemic unfolds, although individual parameters (force of infection, length of latent and infectious period) vary. We also demonstrate that the relationship between different proxies varies as epidemic progresses, with the first period characterised by high ratio of consultations and influenza diagnoses to actual confirmed cases of H1N1. This has important consequences for modelling that is based on reconstructing influenza cases from doctor's reports.

    As an extension of the project in Kato et al. (2009, arXiv:0905.1757), we collected times of superhump maxima for 61 SU UMa-type dwarf novae mainly observed during the 2009-2010 season. The newly obtained data confirmed the basic findings reported in Kato et al. (2009): the presence of stages A-C, as well as the predominance of positive period derivatives during stage B in systems with superhump periods shorter than 0.07 d. There was a systematic difference in period derivatives for systems with superhump periods longer than 0.075 d between this study and Kato et al. (2009). We suggest that this difference is possibly caused by the relative lack of frequently outbursting SU UMa-type dwarf novae in this period regime in the present study. We recorded a strong beat phenomenon during the 2009 superoutburst of IY UMa. The close correlation between the beat period and superhump period suggests that the changing angular velocity of the apsidal motion of the elliptical disk is responsible for the variation of superh...

  17. Surveillance for waterborne disease outbreaks associated with drinking water and other nonrecreational water - United States, 2009-2010.

    2013-09-06

    Despite advances in water management and sanitation, waterborne disease outbreaks continue to occur in the United States. CDC collects data on waterborne disease outbreaks submitted from all states and territories through the Waterborne Disease and Outbreak Surveillance System. During 2009-2010, the most recent years for which finalized data are available, 33 drinking water-associated outbreaks were reported, comprising 1,040 cases of illness, 85 hospitalizations, and nine deaths. Legionella accounted for 58% of outbreaks and 7% of illnesses, and Campylobacter accounted for 12% of outbreaks and 78% of illnesses. The most commonly identified outbreak deficiencies in drinking water-associated outbreaks were Legionella in plumbing systems (57.6%), untreated ground water (24.2%), and distribution system deficiencies (12.1%), suggesting that efforts to identify and correct these deficiencies could prevent many outbreaks and illnesses associated with drinking water. In addition to the drinking water outbreaks, 12 outbreaks associated with other nonrecreational water were reported, comprising 234 cases of illness, 51 hospitalizations, and six deaths. Legionella accounted for 58% of these outbreaks, 42% of illnesses, 96% of hospitalizations, and all deaths. Public health, regulatory, and industry professionals can use this information to target prevention efforts against pathogens, infrastructure problems, and water sources associated with waterborne disease outbreaks.

    The objective of the advanced concentrator program is to develop the technology that will lead to lightweight, highly reflective, accurate, scaleable, and long lived space solar dynamic concentrators. The advanced concentrator program encompasses new and innovative concepts, fabrication techniques, materials selection, and simulated space environmental testing. Fabrication techniques include methods of fabricating the substrates and coating substrate surfaces to produce high quality optical surfaces, acceptable for further coating with vapor deposited optical films. The selected materials to obtain a high quality optical surface include microsheet glass and Eccocoat EP-3 epoxy, with DC-93-500 selected as a candidate silicone adhesive and levelizing layer. The following procedures are defined: cutting, cleaning, forming, and bonding microsheet glass. Procedures are also defined for surface cleaning, and EP-3 epoxy application. The results and analyses from atomic oxygen and thermal cycling tests are used to determine the effects of orbital conditions in a space environment.

    2016-05-01

    Ocean acidification is projected to lower the Ωar of reefal waters by 0.3-0.4 units by the end of century, making it more difficult for calcifying organisms to secrete calcium carbonate while at the same time making the environment more favorable for abiotic and biotic dissolution of the reefal framework. There is great interest in being able to project the point in time when coral reefs will cross the tipping point between being net depositional to net erosional in terms of their carbonate budgets. Periodic in situ assessments of the balance between carbonate production and dissolution that spans seasonal time scales may prove useful in monitoring and formulating projections of the impact of ocean acidification on reefal carbonate production. This study represents the first broad-scale geochemical survey of the rates of net community production (NCP) and net community calcification (NCC) across the Florida Reef Tract (FRT). Surveys were performed at approximately quarterly intervals in 2009-2010 across seven onshore-offshore transects spanning the upper, middle, and lower Florida Keys. Averaged across the FRT, the rates of NCP and NCC were positive during the spring/summer at 62 ± 7 and 17 ± 2 mmol m-2 d-1, respectively, and negative during the fall/winter at -33 ± 6 and -7 ± 2 mmol m-2 d-1. The most significant finding of the study was that the northernmost reef is already net erosional (-1.1 ± 0.4 kg CaCO3 m-2 yr-1) and midreefs to the south were net depositional on an annual basis (0.4 ± 0.1 kg CaCO3 m-2 yr-1) but erosional during the fall and winter. Only the two southernmost reefs were net depositional year-round. These results indicate that parts of the FRT have already crossed the tipping point for carbonate production and other parts are getting close.

Significant differences in age distribution, timing of illness onset, illness complications, underlying medical conditions, critical care admissions, use of mechanical ventilation, and illness outcomes. Both surveillance systems saw the highest numbers of confirmed influenza infection among patients hospitalized in early fall 2009, with sharp declines thereafter. Sentinel hospital surveillance continued to detect hospitalizations for influenza-like illness that were not due to 2009 H1N1 influenza well into March 2010. Compared to influenza surveillance conducted through the Emerging Infections Program, the sentinel hospital influenza surveillance program tended to detect a sicker population of children and adults, including a higher rate of critical illness and mechanical ventilation, and among adults, higher rates of some underlying medical conditions. There were no differences in disease outcomes detected between the 2 systems. Although the 2 surveillance systems were complementary, inherent methodologic variations revealed important differences at season conclusion. The lessons learned should be used to determine the best way to allocate resources to meet the needs of future state and national influenza surveillance efforts.

    Gaua, a little known volcano in the northern part of Vanuatu archipelago, went through a long term eruptive activity between September 2009 and July 2010. The eruption started by a phreatic to phreatomagmatic activity which progressively shifted into a magmatic discharge. The first eruptive phase involved the hydrothermal system in place. The latter was likely influenced by seawater seepage, leading to the formation of anhydrite. Magma involved hereafter this opening phase is of basaltic andesite and basaltic trachyandesite composition (high K calc-alkaline series), typical of the northern part of the Vanuatu archipelago. The 2009-2010 activity discharged at least 184 kt of SO2 and a significant amount of halogens (72 kt Cl and 217 kt F). Such halogen releases indicate that Gaua is a strong source of halogens into the atmosphere. High and sustained amount of F discharges are known to induce health issues and should not be ignored on Gaua island. During this eruption the quiescent and voluminous Lake Letas was slightly affected by the eruption. Nevertheless the hydrothermal discharge point into the lake, situated on the southeastern part of Mt. Garet appeared to be relatively active. At this particular location rock forming elements, leached out from volcanic rock by acid fluids released by the new intrusion of magma, were discharged along with anions into Lake Letas. This release has triggered localized chemistry changes in the lake. We speculate that this discharge has also disturbed the bottom water in a limited perimeter, remobilizing reduced Fe to the surface and subsequently triggering the change in the water color by Fe oxidation.

    Objective To analyze HIV/AIDS epidemic situation and related behaviors among female sex workers (FSWs) in Qinghai, and provide scientific evidence for the development of new HIV prevention strategies. Methods The method of cross-sectional survey was applied to investigate FSWs in 2 sites. The behavior changes of FSWs were observed by continuous surveillance from 2009 to 2010.The blood samples of FSWs were collected and tested for HIV and other sex related diseases. Results The rates of condom use were 84. 3% and 83. 8% at the last commercial sex for site 1 and 2, respectively. The rates of consistent condom use in commercial sex activity were 75. 8% and 69. 9% for site 1 and 2 during the last moth, respectively. Drug use was found in one of the surveillance sites. The awareness of HIV/ AIDS transmission was confirmed as 81. 6% and 75. 8% FSWs on site 1 and 2, respectively. Less than half FSWs attended HIV VCT services (41. 1% and 44. 3% for site 1 and 2, respectively). Most FSWs received intervention services within the last year (77. 2% and 80.1% for site 1 and 2, respectively). HIV infection was confirmed only in site 2 (0.25%) during the 2 years of surveillance. Syphilis (1.6% and 1.8% for site 1 and 2) and HCV (0.5% and 0.1% for site 1 and 2, respectively) infections were found among FSWs. Conclusion HIV prevalence among female sex workers is generally low due to the comprehensive intervention measures, including condom use, behavior intervention, voluntary counseling and testing and public education. Unprotected commercial sex and drug injection were uncommon among FSWs. Achievement of sustained behavior change over extended periods of time is one of the most challenging features of effective behavioral interventions.%目的 分析青海省女性性服务者(FSW)艾滋病相关行为变化及艾滋病病毒(HIV)感染流行趋势,为艾滋病综合防治和科学干预提供信息和依据.方法 对2009-2010年连续开展监测的2个女性性工作者监

    Full Text Available Abstract Background The aim of this study was to estimate the seroprevalence of Coxiella burnetii in dairy goat farms in the Netherlands and to identify risk factors for farm and goat seropositivity before mandatory vaccination started. We approached 334 eligible farms with more than 100 goats for serum sampling and a farm questionnaire. Per farm, median 21 goats were sampled. A farm was considered positive when at least one goat tested ELISA positive. Results In total, 2,828 goat serum samples from 123 farms were available. Farm prevalence was 43.1% (95%CI: 34.3%-51.8%. Overall goat seroprevalence was 21.4% (95%CI: 19.9%-22.9% and among the 53 positive farms 46.6% (95%CI: 43.8%-49.3%. Multivariable logistic regression analysis included 96 farms and showed that farm location within 8 kilometres proximity from a bulk milk PCR positive farm, location in a municipality with high cattle density (≥ 100 cattle per square kilometre, controlling nuisance animals through covering airspaces, presence of cats or dogs in the goat stable, straw imported from abroad or unknown origin and a herd size above 800 goats were independent risk factors associated with Q fever on farm level. At animal level almost identical risk factors were found, with use of windbreak curtain and artificial insemination as additional risk factors. Conclusion In 2009-2010, the seroprevalence in dairy goats in the Netherlands increased on animal and farm level compared to a previous study in 2008. Risk factors suggest spread from relatively closely located bulk milk-infected small ruminant farms, next to introduction and spread from companion animals, imported straw and use of artificial insemination. In-depth studies investigating the role of artificial insemination and bedding material are needed, while simultaneously general biosecurity measures should be updated, such as avoiding companion animals and vermin entering the stables, next to advice on farm stable constructions on

    This report summarizes a 1-year small mammal biodiversity survey conducted on the Oak Ridge National Environmental Research Park (OR Research Park). The task was implemented through the Oak Ridge National Laboratory (ORNL) Natural Resources Management Program and included researchers from the ORNL Environmental Sciences Division, interns in the Oak Ridge Institute for Science and Education Higher Education Research Experiences Program, and ORNL Environmental Protection Services staff. Eight sites were surveyed reservation wide. The survey was conducted in an effort to determine species abundance and diversity of small mammal populations throughout the reservation and to continue the historical inventory of small mammal presence for biodiversity records. This data collection effort was in support of the approved Wildlife Management Plan for the Oak Ridge Reservation, a major goal of which is to maintain and enhance wildlife biodiversity on the Reservation. Three of the sites (Poplar Creek, McNew Hollow, and Deer Check Station Field) were previously surveyed during a major natural resources inventory conducted in 1996. Five new sites were included in this study: Bearden Creek, Rainy Knob (Natural Area 21), Gum Hollow, White Oak Creek and Melton Branch. The 2009-2010 small mammal surveys were conducted from June 2009 to July 2010 on the Oak Ridge National Environmental Research Park (OR Research Park). The survey had two main goals: (1) to determine species abundance and diversity and (2) to update historical records on the OR Research Park. The park is located on the Department of Energy-owned Oak Ridge Reservation, which encompasses 13,580 ha. The primary focus of the study was riparian zones. In addition to small mammal sampling, vegetation and coarse woody debris samples were taken at certain sites to determine any correlations between habitat and species presence. During the survey all specimens were captured and released using live trapping techniques including

    Full Text Available Pandemic influenza A(H1N1pdm09 emerged in Thailand in 2009. A prospective longitudinal adult cohort and household transmission study of influenza-like illness (ILI was ongoing in rural Thailand at the time of emergence. Symptomatic and subclinical A(H1N1pdm09 infection rates in the cohort and among household members were evaluated.A cohort of 800 Thai adults underwent active community-based surveillance for ILI from 2008-2010. Acute respiratory samples from ILI episodes were tested for A(H1N1pdm09 by qRT-PCR; acute and 60-day convalescent blood samples were tested by A(H1N1pdm09 hemagglutination inhibition assay (HI. Enrollment, 12-month and 24-month follow-up blood samples were tested for A(H1N1pdm09 seroconversion by HI. Household members of influenza A-infected cohort subjects with ILI were enrolled in household transmission investigations in which day 0 and 60 blood samples and acute respiratory samples were tested by either qRT-PCR or HI for A(H1N1pdm09. Seroconversion between annual blood samples without A(H1N1pdm09-positive ILI was considered as subclinical infection.The 2-yr cumulative incidence of A(H1N1pdm09 infection in the cohort in 2009/2010 was 10.8% (84/781 with an annual incidence of 1.2% in 2009 and 9.7% in 2010; 83.3% of infections were subclinical (50% in 2009 and 85.9% in 2010. The 2-yr cumulative incidence was lowest (5% in adults born ≤ 1957. The A(H1N1pdm09 secondary attack rate among household contacts was 47.2% (17/36; 47.1% of these infections were subclinical. The highest A(H1N1pdm09 secondary attack rate among household contacts (70.6%, 12/17 occurred among children born between 1990 and 2003.Subclinical A(H1N1pdm09 infections in Thai adults occurred frequently and accounted for a greater proportion of all A(H1N1pdm09 infections than previously estimated. The role of subclinical infections in A(H1N1pdm09 transmission has important implications in formulating strategies to predict and prevent the spread of A(H1N1pdm

  14. NordREG report on the price peaks in the Nordic wholesale market during winter 2009-2010. Final report

    Energy Technology Data Exchange (ETDEWEB)

    2011-01-15

    In winter 2009-2010, prices peaked on three days. The high prices that were experienced in the majority of the Nord Pool Spot price areas initiated a study on the reasons that led to the price spikes and on the possible measures to develop the Nordic market arrangements to avoid such situations in the future. The analysis of the winter 2009-2010 events revealed that there were a number of primary causes for the occurrence of the price peaks and no single individual cause could be pinpointed to bear the key responsibility. The fact that the weather was cold all over the Nordic area in conjunction with the low availability for the Swedish nuclear generation capacity, however, could be indicated as the key underlying causes. The analysis also showed that the way the Nordic transmission capacity is allocated can be listed as an additional factor complementing to the occurrence of the price peaks. Thus, NordREG concluded that a review of the methods of calculating and allocating transmission capacity for the market should be carried out. As a part of this, an analysis that addresses the delimitation of bidding areas and maintenance planning of the transmission network infrastructure should be prepared as well. The flexibility on the demand side has not been very large in the Nordic region. However, the background study prepared by Gaia Consulting showed that even small degree of increased price elasticity could substantially cut the price peaks. This could be seen as an improvement potential of the trading system reflecting the present inability of the market participants to react on the price signals the market place provides. Therefore, NordREG sees that facilitating the appearance of a real price elastic behaviour of the users of electricity can be regarded as one of the key fixes for the problem. Furthermore, NordREG proposes that a consultancy study on how to promote demand flexibility in the Nordic market in a coherent way should be prepared. A further area for

  17. Changes in mean intake of fatty acids and intake of saturated and trans fats from potatoes: NHANES 2005-2006, 2007-2008, and 2009-2010.

    Studies have shown that higher than usual intakes of trans fatty acids (TFAs) have adverse effects on blood lipids. Because of this, in 2006 the US FDA mandated labeling of TFAs on food packages. The food and restaurant industries, including the potato industry, reformulated their foods to reduce or eliminate partially hydrogenated vegetable oils and TFAs. Before mandatory labeling, grain-based desserts, yeast breads, and French-fried potatoes (FFPs) were the top sources of TFAs in the food supply; by 2007, potato food manufacturers and quick-service restaurants had reduced or eliminated TFAs without increasing saturated fatty acids (SFAs). FFPs are no longer a source of TFAs in the food supply. This study examined energy and fatty acid intake among children aged 6-11 y, adolescents aged 12-18 y, and adults aged ≥19 y across 3 time periods by using data from the NHANES 2005-2006, 2007-2008, and 2009-2010. On average, intakes of total energy, total fat, SFAs, and monounsaturated fatty acids (MUFAs) decreased significantly between 2005-2006 and 2009-2010 among children and adolescents; however, the intake of polyunsaturated fatty acids (PUFAs) did not change. Among adults, intakes of total fat, SFAs, and MUFAs decreased; however, total energy and PUFA intake did not change. On the day of the 2009-2010 survey, ∼13% of children and 10% of adolescents reported consuming fried FFPs, whereas <7% of adults reported consumption of fried FFPs. Intakes of SFAs and TFAs from fried FFPs decreased significantly between 2005-2006 and 2009-2010 among children, adolescents, and adults. This study confirms that intake of TFAs from FFPs is trivial.

    We searched for possible biomarker gases on Mars in the 2009-2010 observing season, emphasizing nine molecules (H2_O, CH_4_, C2_H_6_, C2_H_4_, CH3_OH, H_2_CO, H2_S, and N_2_O) of fundamental astrobiological importance along with HDO and CO2_. Our search utilized Earth’s most advanced ground-based infrared spectroscopic facilities in a campaign of several dozen observing runs spanning the period 19 August 2009 to 10 June 2010. Over this interval (L_s_ = 324 - 103 degrees), the season in Mars’ Northern hemisphere progressed from mid-winter, through vernal equinox and spring, and into early summer. We used long-slit high-resolution infrared spectrometers at the Keck and NASA-IRTF observatories in Hawaii, and the European Southern Observatory in Chile (VLT, Paranal). The spectral resolving powers ranged from ~ 35,000 (NIRSPEC/Keck and CSHELL/IRTF) to ~ 90,000 (CRIRES, VLT). At the sub-Earth point, the spatial resolution in non-AO mode ranged from ~600 km (FWHM) to ~ 400 km at Keck and IRTF. Using the adaptive optics (AO) mode at Keck and at VLT, we achieved an improved resolution of ~250 km (FWHM). We mapped the planet over the Earth-facing hemisphere by orienting the slit North-South in longitude and stepping it East-West across the planet, and we acquired deep searches over restricted longitude ranges by holding the slit fixed in position and taking sequential spectra as Mars rotated under it. Spectral lines of CO2_, H_2_O, HDO, and O2_ (a^1^Δg_) are obvious, even in the raw data. In the methane region near 3.3µm, removal of terrestrial and solar spectral lines revealed multiple lines of Mars H_2_O and CO2_, from which we extracted 2-D (lat-long) maps of Martian water vapor, atmospheric surface pressure and temperature. Subtraction of these features provided highly sensitive searches for trace gases. Preliminary results of searches for CH_4_, C2_H_4_, and C2_H_6_ will be presented in this paper. Radeva et al.

Joint pain was significantly associated with CHIKV positivity (P = 0.0156). Presence/absence of certain clinical features varied with age (P chikungunya virus infection in children from India during 2009-2010 showed high proportion of CHIKV infection in Southern region of India compared to Northern region. The circulating CHIKV strains were of Indian Ocean Lineage (IOL) group within the East, Central, and South African (ECSA) genotype. However few amino acid changes were observed in E1 polypeptide with reference to African strain S-27 (AF369024). Further studies are needed to know the implications of these changes in vector-pathogen compatibility and host-pathogen interactivity. As a whole, this study highlighted the proportion of CHIKV cases, lineage of causative strain and evolutionary pattern of circulating strain in terms of amino acid changes in the structural protein. © 2015 Wiley Periodicals, Inc.

    Lance F. Bosart, Heather M. Archambault, and Jason M. Cordeira Department of Atmospheric and Environmental Sciences, University at Albany, State University of New York, Albany, New York The Northern Hemisphere (NH) planetary-scale circulation during winter 2009-2010 was characterized by an unusual combination of persistent high-latitude blocking and southward-displaced storm tracks, manifest by a strongly negative Arctic Oscillation (AO), in conjunction with a moderate El Nino event. The high-latitude blocking activity and southward-displaced storm tracks supported episodic cold-air outbreaks and enhanced storminess over parts of midlatitude eastern Asia, eastern North America, and western Europe as well as anomalous warmth over northeastern Canada and Greenland that delayed sea ice formation and ice thickening in these areas during winter 2009-2010. Although somewhat less extreme than winter 2009-2010, the first half of winter 2010-2011 was also characterized by high-latitude blocking and southward-displaced storm tracks (manifest by negative values of the AO) while the Pacific-North American (PNA), initially negative, became neutral in late December and most of January. Winter 2010-2011 was characterized by moderate La Nina conditions in contrast to moderate El Nino conditions that prevailed during winter 2009-2010. Despite the reversal of the ENSO phase from winter 2009-2010 to winter 2010-2011, high-latitude blocking activity and the associated southward-displaced storm tracks again allowed for episodic cold-air outbreaks and enhanced storminess over parts of midlatitude eastern Asia, central and eastern North America, and western Europe with delayed sea ice formation and thickening over the Davis Strait and adjacent regions during the first half of winter 2010-2011. Beginning in late January and continuing through early February 2011 the phase of the AO and the PNA reversed with the AO and PNA becoming positive and negative, respectively. This linked AO

    Background FCTC Article 11 Guidelines recommend that health warning labels (HWLs) should occupy at least 50% of the package, but the tobacco industry claims that increasing the size would not lead to further benefits. This article reports the first population study to examine the impact of increasing HWL size above 50%. We tested the hypothesis that the 2009/2010 enhancement of the HWLs in Uruguay would be associated with higher levels of effectiveness. Methods Data were drawn from a cohort of adult smokers (≥18 years) participating in the International Tobacco Control (ITC) Uruguay Survey. The probability sample cohort was representative of adult smokers in 5 cities. The surveys included key indicators of HWL effectiveness. Data were collected in 2008/09 (pre-policy: Wave 2) and 2010/11 (post-policy: Wave 3). Results Overall, 1746 smokers participated in the study at Wave 2 (n=1,379) and Wave 3 (n=1,411). Following the 2009/2010 HWL changes in Uruguay (from 50% to 80% in size), all indicators of HWL effectiveness increased significantly [noticing HWLs: odds ratio (OR)=1.44, p=0.015; reading HWLs: OR=1.42, p=0.002; impact of HWLs on thinking about risks of smoking: OR=1.66, p<0.001; HWLs increasing thinking about quitting: OR=1.76, p<0.001; avoiding looking at the HWLs: OR=2.35, p<.001; and reports that HWLs stopped smokers from having a cigarette “many times”: OR=3.42, p<0.001]. Conclusions The 2009/2010 changes to HWLs in Uruguay, including a substantial increment in size, led to increases of key HWL indicators, thus supporting the conclusion that enhancing HWLs beyond minimum guideline recommendations can lead to even higher levels of effectiveness.

    2015-03-01

    Global water shortages due to droughts and population growth have created increasing interest in water reuse and recycling and, concomitantly, development of effective water treatment processes. Pressured membrane processes, in particular reverse osmosis, have been adopted in water treatment industries and utilities despite the relatively high operational cost and energy consumption. However, emerging contaminants are present in reverse osmosis concentrate in higher concentrations than in the feed water, and have created challenges for treatment of the concentrate. Further, standards and guidelines for assessment and treatment of newly identified contaminants are currently lacking. Research is needed regarding the treatment and disposal of emerging contaminants of concern in reverse osmosis concentrate, in order to develop cost-effective methods for minimizing potential impacts on public health and the environment. This paper reviews treatment options for concentrate from membrane processes. Barriers to emerging treatment options are discussed and novel treatment processes are evaluated based on a literature review. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Response surface analysis methodology was used to optimize the concentrate process of phenolic acids from Lonicera japonica by nanofiltration technique. On the basis of the influences of pressure, temperature and circulating volume, the retention rate of neochlorogenic acid, chlorogenic acid and 4-dicaffeoylquinic acid were selected as index, molecular weight cut-off of nanofiltration membrane, concentration and pH were selected as influencing factors during concentrate process. The experiment mathematical model was arranged according to Box-Behnken central composite experiment design. The optimal concentrate conditions were as following: nanofiltration molecular weight cut-off, 150 Da; solutes concentration, 18.34 µg/mL; pH, 4.26. The predicted value of retention rate was 97.99% under the optimum conditions, and the experimental value was 98.03±0.24%, which was in accordance with the predicted value. These results demonstrate that the combination of Box-Behnken design and response surface analysis can well optimize the concentrate process of Lonicera japonica water-extraction by nanofiltration, and the results provide the basis for nanofiltration concentrate for heat-sensitive traditional Chinese medicine.

    Full Text Available BACKGROUND: A multicentre case-control study based on sentinel practitioner surveillance networks from seven European countries was undertaken to estimate the effectiveness of 2009-2010 pandemic and seasonal influenza vaccines against medically attended influenza-like illness (ILI laboratory-confirmed as pandemic influenza A (H1N1 (pH1N1. METHODS AND FINDINGS: Sentinel practitioners swabbed ILI patients using systematic sampling. We included in the study patients meeting the European ILI case definition with onset of symptoms >14 days after the start of national pandemic vaccination campaigns. We compared pH1N1 cases to influenza laboratory-negative controls. A valid vaccination corresponded to >14 days between receiving a dose of vaccine and symptom onset. We estimated pooled vaccine effectiveness (VE as 1 minus the odds ratio with the study site as a fixed effect. Using logistic regression, we adjusted VE for potential confounding factors (age group, sex, month of onset, chronic diseases and related hospitalizations, smoking history, seasonal influenza vaccinations, practitioner visits in previous year. We conducted a complete case analysis excluding individuals with missing values and a multiple multivariate imputation to estimate missing values. The multivariate imputation (n = 2902 adjusted pandemic VE (PIVE estimates were 71.9% (95% confidence interval [CI] 45.6-85.5 overall; 78.4% (95% CI 54.4-89.8 in patients <65 years; and 72.9% (95% CI 39.8-87.8 in individuals without chronic disease. The complete case (n = 1,502 adjusted PIVE were 66.0% (95% CI 23.9-84.8, 71.3% (95% CI 29.1-88.4, and 70.2% (95% CI 19.4-89.0, respectively. The adjusted PIVE was 66.0% (95% CI -69.9 to 93.2 if vaccinated 8-14 days before ILI onset. The adjusted 2009-2010 seasonal influenza VE was 9.9% (95% CI -65.2 to 50.9. CONCLUSIONS: Our results suggest good protection of the pandemic monovalent vaccine against medically attended pH1N1 and no effect of the

    This report provides a summary of results from studies on invertebrate bioaccumulation of potential contaminants associated with a major fly ash spill into the Emory River following the failure of a dike at the Tennessee Valley Authority's (TVA) Kingston Fossil Plant (KIF) in Kingston, Tennessee, in late December 2008. Data included in this report cover samples collected in calendar years 2009 and 2010. Samples collected from most sites in 2009 were processed by two different laboratories using different approved U.S. Environmental Protection Agency (EPA) analytical methods: ALS Laboratory Group in Ft. Collins, CO, processed sampling using EPA method 6010 (but method 6020 for uranium and SW7470 for mercury), and PACE Analytical in Minneapolis, MN, used EPA method 6020. A preliminary evaluation of results from both laboratories indicated that some differences exited in measured concentrations of several elements, either because of specific differences of the two methods or inter-laboratory differences. While concentration differences between the laboratories were noted for many elements, spatial trends depicted from the results of both methods appeared to be similar. However, because samples collected in the future will be analyzed by Method 6020, only the results from PACE were included in this report to reduce data variation potentially associated with inter-laboratory and analytical method differences.

    Full Text Available Shellfish may pose a risk in food safety, which is why the monitoring of the waters must be classified before the collection of live bivalve molluscs. These animals are filter feeders that accumulate microorganisms and chemicals present in water. Regulation (EC 854/04 provides that Member States ensure the classification of production areas of bivalve molluscs and establish a surveillance system on the areas of classification and the production facilities that allows continuous monitoring of the healthiness of these products and health quality of water. This paper reports the results of the microbiological production areas of Venus gallina pertaining to the Z.T. 11 Fermo for the years 2009-2010. From our experience, it is the important to have an adequate monitoring regional system and the involvement of professionals in this sector for an effective prevention. So it is of great importance to involve all the different workers in this field.

    The 2009-2010 H1N1 influenza pandemic has highlighted the importance of global health surveillance. Increasingly, global alerts are based on 'unexpected' 'events' detected by surveillance systems grounded in particular places. An emerging global governance literature investigates the supposedly disruptive impact of public health emergencies on mobilities in an interdependent world. Little consideration has been given to the varied scales of governance--local, national and global--that operate at different stages in the unfolding of an 'event', together with the interactions and tensions between them. By tracking the chronology of the H1N1 pandemic, this paper highlights an emergent dialogue between local and global scales. It also draws attention to moments of national autonomy across the global North and South which undermined the WHO drive for transnational cooperation.

    Full Text Available This paper addresses the rainfall episodes occurred during spring-summer season 2009/2010 in Palmas (TO, and their impacts on its urban area, construction of which hardly exceeds recent 21 years in 2010. It also constitutes a preliminary analysis about the genesis of the rhythm and of the climate exceptionalities in the study area, since there are few studies of Geographical Climatology about the state of Tocantins. The main elements of the atmospheric circulation were identifi ed through rhythmic analysis, as well as the stormwater impacts were also listed and reported by a local daily newspaper. These impacts were focused on their spatial distribution, seeking to emphasize the elements of vulnerability of the affected spots, as well as the selectivity and news content. The results allowed to give an initial overview on the relation between the rainfall, the geographical and human activities in Palmas, revealing aspects of its urban planning and its vulnerability to climate exceptionalities.

    Mannheimia haemolytica consistently causes severe bronchopneumonia and rapid death of bighorn sheep (Ovis canadensis) under experimental conditions. However, Bibersteinia trehalosi and Pasteurella multocida have been isolated from pneumonic bighorn lung tissues more frequently than M. haemolytica by culture-based methods. We hypothesized that assays more sensitive than culture would detect M. haemolytica in pneumonic lung tissues more accurately. Therefore, our first objective was to develop a PCR assay specific for M. haemolytica and use it to determine if this organism was present in the pneumonic lungs of bighorns during the 2009-2010 outbreaks in Montana, Nevada, and Washington, USA. Mannheimia haemolytica was detected by the species-specific PCR assay in 77% of archived pneumonic lung tissues that were negative by culture. Leukotoxin-negative M. haemolytica does not cause fatal pneumonia in bighorns. Therefore, our second objective was to determine if the leukotoxin gene was also present in the lung tissues as a means of determining the leukotoxicity of M. haemolytica that were present in the lungs. The leukotoxin-specific PCR assay detected leukotoxin gene in 91% of lung tissues that were negative for M. haemolytica by culture. Mycoplasma ovipneumoniae, an organism associated with bighorn pneumonia, was detected in 65% of pneumonic bighorn lung tissues by PCR or culture. A PCR assessment of distribution of these pathogens in the nasopharynx of healthy bighorns from populations that did not experience an all-age die-off in the past 20 yr revealed that M. ovipneumoniae was present in 31% of the animals whereas leukotoxin-positive M. haemolytica was present in only 4%. Taken together, these results indicate that culture-based methods are not reliable for detection of M. haemolytica and that leukotoxin-positive M. haemolytica was a predominant etiologic agent of the pneumonia outbreaks of 2009-2010.

    Soil gas, soil, and water were assessed for organic and inorganic constituents at the former hospital landfill located in a 75-acre study area near the Dwight D. Eisenhower Army Medical Center, Fort Gordon, Georgia, from April to September 2010. Passive soil-gas samplers were analyzed to evaluate organic constituents in the hyporheic zone of a creek adjacent to the landfill and soil gas within the estimated boundaries of the former landfill. Soil and water samples were analyzed to evaluate inorganic constituents in soil samples, and organic and inorganic constituents in the surface water of a creek adjacent to the landfill, respectively. This assessment was conducted to provide environmental constituent data to Fort Gordon pursuant to requirements of the Resource Conservation and Recovery Act Part B Hazardous Waste Permit process. Results from the hyporheic-zone assessment in the unnamed tributary adjacent to the study area indicated that total petroleum hydrocarbons and octane were the most frequently detected organic compounds in groundwater beneath the creek bed. The highest concentrations for these compounds were detected in the upstream samplers of the hyporheic-zone study area. The effort to delineate landfill activity in the study area focused on the western 14 acres of the 75-acre study area where the hyporheic-zone study identified the highest concentrations of organic compounds. This also is the part of the study area where a debris field also was identified in the southern part of the 14 acres. The southern part of this 14-acre study area, including the debris field, is steeper and not as heavily wooded, compared to the central and northern parts. Fifty-two soil-gas samplers were used for the July 2010 soil-gas survey in the 14-acre study area and mostly detected total petroleum hydrocarbons, and gasoline and diesel compounds. The highest soil-gas masses for total petroleum hydrocarbons, diesel compounds, and the only valid detection of perchloroethene

    Soil gas and soil were assessed for organic and inorganic contaminants at the former military police range at Fort Gordon, Georgia, from May to September 2010. The assessment evaluated organic contaminants in soil-gas samplers and inorganic contaminants in soil samples. This assessment was conducted to provide environmental contamination data to Fort Gordon pursuant to requirements of the Resource Conservation and Recovery Act Part B Hazardous Waste Permit process. Soil-gas samplers deployed and collected from May 20 to 24, 2010, identified masses above method detection level for total petroleum hydrocarbons, gasoline-related and diesel-related compounds, and chloroform. Most of these detections were in the southwestern quarter of the study area and adjacent to the road on the eastern boundary of the site. Nine of the 11 chloroform detections were in the southern half of the study area. One soil-gas sampler deployed adjacent to the road on the southern boundary of the site detected a mass of tetrachloroethene greater than, but close to, the method detection level of 0.02 microgram. For soil-gas samplers deployed and collected from September 15 to 22, 2010, none of the selected organic compounds classified as chemical agents and explosives were detected above method detection levels. Inorganic concentrations in the five soil samples collected at the site did not exceed the U.S. Environmental Protection Agency regional screening levels for industrial soil and were at or below background levels for similar rocks and strata in South Carolina.

    The main biochemicals (such as lignin, protein, cellulose, sugar, starch, chlorophyll and water) of vegetation are directly or indirectly involved in major ecological processes, such as the functions of terrestrial ecosystems (i.e., nutrient-cycling processes, primary production, and decomposition). Remote sensing techniques provide a very convenient way of data acquisition capable of covering a large area several times during one season, so it can play a unique and essential role provided that we can relate remote sensing measurements to the biochemical characteristics of the Earth surface in a reliable and operational way. The application of remote sensing techniques for the estimation of canopy biochemicals was reviewed. Three methods of estimating biochemical concentrations of vegetation were included in this paper: index, stepwise multiple linear regression, and stepwise multiple linear regression based on a model of the forest crown. In addition, the vitality and potential applying value are stressed.

    One of the unsolved problem areas of low level radioactive waste management is the radiolabeled material generated by life sciences research and clinical diagnostics. In hundreds of academic, biotechnology, and pharmaceutical institutions, there exists large amounts of both aqueous and organic solutions containing radioactively labeled nucleic acids, proteins, peptides, and their monomeric components. We have invented a generic slurry capable of binding all these compounds, thus making it possible to concentrate and solidify the radioactive molecules into a very small and lightweight material. The slurry can be contained in both large and small disposal plastic devices designed for the size of any particular operation. The savings in disposal costs and convenience of this procedure is a very attractive alternative to the present methods of long and short term storage. Additionally, the slurry can remove radiolabeled biological compounds from organic solvents, thus solving the major problem of {open_quotes}mixed{close_quotes} waste. We are now proceeding with the field application stage for the testing of these devices and anticipate widespread use of the process. We also are exploring the use of the slurry on other types of liquid low level radioactive waste.

By chosing the following research theme: Tourism and development in the euroregional context I felt the need to find out more answers regarding the afore mentioned problem. In consequence I started to consult the statistics recorded in our country concerning the number of overnight stays registered in Romania during the period June-August 2009/2010, in order to check whether an error has sneaked in. The research methodology employed consisted in the use of the insse.ro site, in order to gather representative data for the period June-September 2009/2010, regarding the number of nights spent by foreign and Romanian tourists in Romania. For this study to be even more representative I have established Romania's main touristic areas preferred by Romanian and foreign tourists. Following the data collected, unfortunately, it has been confirmed the situation presented by Eurostat in the table at the beginning of paper on the number of overnight stays registered in Romania. According to the data presented in this table, Romania ranks last in the EU, registering in 2010 a rate of only 15% of total nights spent by non-residents in our country. I also tried to find answer to the following questions: Which are Romanians favorite touristic areas? In which tourist area of Romania has been recorded the highest number of overnight stays of foreign tourists? Why the number of

    Pandemic influenza A(H1N1) 2009 virus was first detected in Japan in May 2009 and continued to circulate in the 2010-2011 season. This study aims to characterize human influenza viruses circulating in Japan in the pandemic and post-pandemic periods and to determine the prevalence of antiviral-resistant viruses. Respiratory specimens were collected from patients with influenza-like illness on their first visit at outpatient clinics during the 2009-2010 and 2010-2011 influenza seasons. Cycling probe real-time PCR assays were performed to screen for antiviral-resistant strains. Sequencing and phylogenetic analysis of the HA and NA genes were done to characterize circulating strains. In the pandemic period (2009-2010), the pandemic influenza A(H1N1) 2009 virus was the only circulating strain isolated. None of the 601 A(H1N1)pdm09 virus isolates had the H275Y substitution in NA (oseltamivir resistance) while 599/601 isolates (99.7%) had the S31N substitution in M2 (amantadine resistance). In the post-pandemic period (2010-2011), cocirculation of different types and subtypes of influenza viruses was observed. Of the 1,278 samples analyzed, 414 (42.6%) were A(H1N1)pdm09, 525 (54.0%) were A(H3N2) and 33 (3.4%) were type-B viruses. Among A(H1N1)pdm09 isolates, 2 (0.5%) were oseltamivir-resistant and all were amantadine-resistant. Among A(H3N2) viruses, 520 (99.0%) were amantadine-resistant. Sequence and phylogenetic analyses of A(H1N1)pdm09 viruses from the post-pandemic period showed further evolution from the pandemic period viruses. For viruses that circulated in 2010-2011, strain predominance varied among prefectures. In Hokkaido, Niigata, Gunma and Nagasaki, A(H3N2) viruses (A/Perth/16/2009-like) were predominant whereas, in Kyoto, Hyogo and Osaka, A(H1N1)pdm09 viruses (A/New_York/10/2009-like) were predominant. Influenza B Victoria(HA)-Yamagata(NA) reassortant viruses (B/Brisbane/60/2008-like) were predominant while a small proportion was in Yamagata lineage. Genetic

    Stratospheric sudden warming (SSW) is a dramatic phenomenon of the winter stratosphere in which the distribution of chemical constituents, associated chemical tendency, and transport of chemical constituents differ significantly inside and outside of the polar vortex. In this study, the chemical constituent distributions in the major SSW of 2009/2010 were simulated by the Model for Interdisciplinary Research on Climate 3.2-Chemistry-Climate Model (CCM) nudged toward the European Center for Medium-Range Weather Forecasts-Interim Re-Analysis data. The results were compared with Superconducting Submillimeter-Wave Limb-Emission Sounder (SMILES) and Microwave Limb Sounder (MLS) observations. In addition, ozone tendency due to ozone transport and chemical ozone loss in the high-latitude lower stratosphere before and after the SSW was analyzed for the period from 1 January 2010 to 11 February 2010. The evolution and distribution of ozone and HCl inside/outside the polar vortex associated with the vortex shift to the midlatitudes in January are quite similar between SMILES and MLS. Those of ClO are also similar, considering the difference in the local time for the measurement. Analyses of the nudged CCM run indicate that inside the polar vortex at 50 hPa, the ozone concentration increased moderately owing to partial cancelation between the large negative ozone tendency due to chemical ozone destruction and large positive ozone tendency due to horizontal ozone influx from outside of the vortex as well as downward advection. In the region of a high ozone concentration with the same area as that of the polar vortex at 50 hPa, the large increase in ozone was primarily due to a downward advection of ozone. SMILES and MLS observations, nudged CCM simulations, and ozone tendency analyses revealed a highly longitudinal dependent ozone tendency at high latitudes during the SSW.

The SaV detection rate was 7.5% (71/948) according to reverse transcription-polymerase chain reaction. A high SaV detection rate of 13.5% was observed among children 4 years of age. The highest SaV detection rate was observed in June (19.2%), followed by July (11.1%). The detected SaV included 7 genotypes: GI.1, GI.2, GII.3, GII.1, GI.3, GII.2, and GV, in order of decreasing prevalence. In comparison, the HAstV detection rate was 4.2% (40/948). The HAstV detection rate among children 4 years of age was 12.2%. The HAstV detection rate was highest in July (13.9%), followed by May (10.5%) and August (6.7%). The detected HAstVs included genotypes 1, 4, 6, and 8. The most prevalent genotype was 1, followed by 4 and 8. This report provides an epidemiological overview of SaV and HAstV infection in Nara Prefecture, Japan.

    Coral skeletons contain records of past environmental conditions due to their long life span and well calibrated geochemical signatures. C and O isotope records of corals are especially interesting, because they can highlight multidecadal variability of local climate conditions beyond the instrumental record, with high fidelity and sub-annual resolution. Although, in order to get an optimal geochemical signal in coral skeleton, sampling strategies must be followed. Here we report one of the first coral-based isotopic record from the Equatorial South Atlantic from two colonies of Porites astreoides from the Rocas Atoll (offshore Brazil), a new location for climate reconstruction. We present time series of isotopic variation from profiles along the corallite valley of one colony and the apex of the corallite fan of the other colony. Significant differences in the isotopic values between the two colonies are observed, yet both record the 2009/2010 El Niño event - a period of widespread coral bleaching - as anomalously negative δ18O values (up to -1 permil). δ13C is found to be measurably affected by the El Niño event in one colony, by more positive values (+0.39 ‰), and together with a bloom of endolithic algae, may indicate physiological alteration of this colony. Our findings indicate that corals from the Rocas Atoll can be used for monitoring climate oscillations in the tropical South Atlantic Ocean.

  19. Individual Vaccination as Nash Equilibrium in a SIR Model with Application to the 2009-2010 Influenza A (H1N1) Epidemic in France.

    The vaccination against ongoing epidemics is seldom compulsory but remains one of the most classical means to fight epidemic propagation. However, recent debates concerning the innocuity of vaccines and their risk with respect to the risk of the epidemic itself lead to severe vaccination campaign failures, and new mass behaviors appeared driven by individual self-interest. Prompted by this context, we analyze, in a Susceptible-Infected-Recovered model, whether egocentric individuals can reach an equilibrium with the rest of the society. Using techniques from the "Mean Field Games" theory, we extend previous results and show that an equilibrium exists and characterizes completely the individual best vaccination strategy (with or without discounting). We also compare with a strategy based only on overall societal optimization and exhibit a situation with nonnegative price of anarchy. Finally, we apply the theory to the 2009-2010 Influenza A (H1N1) vaccination campaign in France and hint that a group of individuals stopped vaccinating at levels that indicated a pessimistic perception of the risk of the vaccine.

    The growing demand for fresh water is partially satisfied by desalination plants that increasingly use membrane technologies and among them reverse osmosis to produce purified water. Operating with water recoveries from 35% to 85% RO plants generate huge volumes of concentrates containing all the retained compounds that are commonly discharged to water bodies and constitute a potentially serious threat to marine ecosystems; therefore there is an urgent need for environmentally friendly management options of RO brines. This paper gives an overview on the potential treatments to overcome the environmental problems associated to the direct discharge of RO concentrates. The treatment options have been classified according to the source of RO concentrates and the maturity of the technologies. For the sake of clarity three different sources of RO concentrates are differentiated i) desalination plants, ii) tertiary processes in WWTP, and iii) mining industries. Starting with traditional treatments such as evaporation and crystallization other technologies that have emerged in last years to reduce the volume of the concentrate before disposal and with the objective of achieving zero liquid discharge and recovery of valuable compounds from these effluents are also reviewed. Most of these emerging technologies have been developed at laboratory or pilot plant scale (see Table 1). With regard to RO concentrates from WWTP, the manuscript addresses recent studies that are mainly focused on reducing the organic pollutant load through the application of innovative advanced oxidation technologies. Finally, works that report the treatment of RO concentrates from industrial sources are analyzed as well.

Main results: The attitudes and opinions of the general population and risk groups gradually change from a state of initial concern, caused by the social alert promoted by the media to a reduced perceived risk. The lack of trust in the information sources and the need for a greater involvement of the authorities also appear. Conclusion: The authorities must rely on advanced information systems, train personnel of health services and organize their work on coordination and involvement of all sectors.

    By using the observed monthly mean data over 160 stations of China and NCAR/NCEP reanalysis data, the generalized equilibrium feedback assessment(GEFA) method, combined with the methods of EOF analysis, correlation and composite analysis, is used to explore the influence of different SST modes on the cold-northeast/warm-southwest pattern(CNE-WSN). The results show that the 2009/2010 winter air temperature oscillation mode between northern and southern parts of China is closely related to the corresponding sea surface temperature anomalies(SSTA) and its associated atmospheric circulation anomalies. The above-mentioned air temperature mode, exhibiting a warming in Northeast China and a cooling in Southwest China, is significantly forced by the El Nino mode and the North Atlantic SSTA mode, which have three poles. Under the influence of SSTA modes, the surface northerly flow transported cold air to north and northeast China, resulting in low temperatures in the region. Meanwhile, the mid-latitude westerlies are intensified and the polar cold air are entrenched in high latitudes and cannot affect the Southwest, resulting in the warming of the Southwest.%利用中国160个台站和NCEP再分析资料,引入综合分析气候反馈的统计方法——广义平衡反馈方法(GEFA),结合EOF、相关合成分析,探讨2009/2010年中国冬季气温异常型的成因.结果表明:2009/2010年中国冬季气温出现的东北冷西南暖分布型与同期海温异常及其相联系的大气环流异常有密切的关系.其中赤道中东太平洋海温异常的El Nifio型和赤道大西洋海温异常“正-负-正”三极型模态对2009/2010年中国冬季气温东北冷西南暖分布型有显著的强迫作用.上述海温异常型影响了大气环流异常,中高纬度地面偏北气流将冷空气输送到华北东北地区,致使该地区冬季气温偏低,同时中纬度西风增强,极地冷空气被迫盘踞在高纬,不能影响到西南地区,导致西南地区较常年更暖.

  6. Market concentration and technological innovation in a dynamic model of growth and distribution

    Full Text Available This paper develops a post Keynesian macromodel of growth and distribution in which endogenous technological innovation plays a pivotal role. The innovationrate is made quadratic in market concentration, to capture a plausible neo-Schumpeterian non-linear influence of market structure on firms' propensity to innovate. Concentration is endogenous, though, since under neo-Schumpeterian competition the relation between market structure and technical change cuts both ways. Investment will then be non-linear in concentration, and the effect of changes in concentration on capacity utilisation, growth and distribution will depend on the level of concentration. Demand also plays a role, with capacity utilisation andgrowth rising with the wage share. The dynamic stability properties of the system will depend on the direction and relative strength of the technological innovation effects with respect to the demand ones, and on the relative bargaining power of workers and capitalists.

    Introducción: el síndrome metabólico (SM) es un conjunto de factores de riesgo que predisponen a padecer enfermedad cardiovascular y diabetes. Una dieta poco saludable juega un rol importante en el desarrollo de esta condición. En este estudio evaluamos la prevalencia de síndrome metabólico y su asociación con la calidad de la dieta en adultos chilenos. Métodos: se analizaron los datos de 2.561 adultos mayores de 18 años de edad incluidos en la última Encuesta Nacional de Salud (ENS 2009-2010), que contaban con información para el diagnóstico de síndrome metabólico siguiendo los criterios de ATP III-NCEP. La frecuencia de consumo de pescado, cereales integrales, frutas, verduras y lácteos fue analizada y asociada a la presencia de SM. Por medio de un índice de dieta saludable (IDS), se evaluó la calidad global de la dieta y se correlacionó con la prevalencia de este síndrome. Resultados: un menor consumo de cereales integrales se asoció a una mayor prevalencia de síndrome metabólico (OR = 1,78; 95% IC: 1,088-2,919; p = 0,022). El IDS mostró que el consumo de alimentos tiene mejor calidad en mujeres y a mayor edad y mejor nivel educacional. Un IDS mayor riesgo de síndrome metabólico (OR IDS < 3 / IDS ≥ 3 = 3,69 95% IC:1,884- 7,225, p < 0,001). Conclusión: la población adulta chilena presenta una elevada prevalencia de síndrome metabólico asociado al consumo de una alimentación de mala calidad.

    The developing world, including countries like India, has become a major target for the tobacco industry to market its products. This study examines the influence of the marketing (advertising and promotion) of tobacco products on the use of tobacco by adults (ages 15 and over) in India. Data from Global Adult Tobacco Survey 2009-2010 was analyzed using methods for complex (clustered) sample designs. Multivariate logistic regression was employed to predict the use of different tobacco products by level of exposure to tobacco marketing using adults who have never used tobacco as the reference category. Odds ratios (ORs) were adjusted for education, gender, age, state of residence, wealth index, and place of residence (urban/rural). Adults in India were almost twice as likely to be current smokers (versus never users) when they were exposed to a moderate level of bidi or cigarette marketing. For bidis, among adults with high exposure, the OR for current use was 4.57 (95% confidence interval [CI]: 1.6, 13.0). Adults were more likely to be current users of smokeless tobacco (SLT) with even a low level of exposure to SLT marketing (OR = 1.24 [95% CI: 1.1, 1.4]). For SLT, the ORs showed an increasing trend (P for trend marketing (minimum, OR = 1.25 [1.1-1.4]; moderate, OR = 1.38 [1.1-1.8]; and high, OR = 2.73 [1.8-4.2]), with the trend highly significant (P marketing of tobacco products, which may take the form of advertising at the point of sale, sales or a discounted price, free coupons, free samples, surrogate advertisements, or any of several other modalities, increased prevalence of tobacco use among adults. An increasing level of exposure to direct and indirect advertisement and promotion is associated with an increased likelihood of tobacco use.

  9. Re-emergence of dengue virus type 3 in Canton, China, 2009-2010, associated with multiple introductions through different geographical routes.

    Full Text Available BACKGROUND: Endemic dengue virus type 3 (DENV-3 infections have not been reported in Canton, China, since 1980. In March 2009, DENV-3 was isolated for the second time, occurring about 30 years after the previous circulation. In August, 3 other cases emerged. One much larger outbreak occurred again in 2010. To address the origin and particularly to determine whether the outbreaks were caused by the same viral genotype, we investigated the epidemiological and molecular characteristics of the introduction, spread and genetic microevolution of DENV-3 involved. METHODOLOGY/PRINCIPAL FINDINGS: Three imported cases (index-1,2,3 separately traveled back from Vietnam, India and Tanzania, resulted in 1, 3 and 60 secondary autochthonous cases, respectively. In autochthonous cases, 64.6% positive in IgM anti-DENV and 18.6% in IgG from a total of 48 submitted serum samples, accompanied by 7 DENV-3 isolates. With 99.8%, 99.7%, and 100% envelope gene nucleotidic identity, 09/GZ/1081 from index-1 and endemic strain (09/GZ/1483 belonged to genotype V; 09/GZ/10616 from index-2 and endemic strains (09/GZ/11144 and 09/GZ/11194 belonged to genotype III Clade-A; and 10/GZ/4898 from index-3 and all four 2010 endemic DENV-3 strains belonged to genotype III Clade-B, respectively. CONCLUSIONS/SIGNIFICANCE: Both epidemiological and phylogenetic analyses showed that the 2010 outbreak of dengue was not a reemergence of the 2009 strain. Introductions of different genotypes following more than one route were important contributory factors for the 2009-2010 dengue epidemics/outbreaks in Canton. These findings underscore the importance of early detection and case management of imported case in preventing large-scale dengue epidemics among indigenous peoples of Canton.

    In response to the 2009-2010 influenza A(H1N1)pdm09 pandemic, a mass vaccination programme with the AS03-adjuvanted influenza A(H1N1) vaccine Pandemrix was initiated in Sweden. Unexpectedly, there were a number of narcolepsy cases amongst vaccinated children and adolescents reported. In this review, we summarize the results of a joint cross-disciplinary national research effort to investigate the adverse reaction signal from the spontaneous reporting system and to better understand possible causative mechanisms. A three- to fourfold increased risk of narcolepsy in vaccinated children and adolescents was verified by epidemiological studies. Of importance, no risk increase was observed for the other neurological and autoimmune diseases studied. Genetic studies confirmed the association with the allele HLA-DQB1*06:02, which is known to be related to sporadic narcolepsy. Furthermore, a number of studies using cellular and molecular experimental models investigated possible links between influenza vaccination and narcolepsy. Serum analysis, using a peptide microarray platform, showed that individuals who received Pandemrix exhibited a different epitope reactivity pattern to neuraminidase and haemagglutinin, as compared to individuals who were infected with H1N1. Patients with narcolepsy were also found to have increased levels of interferon-gamma production in response to streptococcus-associated antigens. The chain of patient-related events and the study results emerging over time were subjected to intense nationwide media attention. The importance of transparent communication and collaboration with patient representatives to maintain public trust in vaccination programmes is also discussed in the review. Organizational challenges due to this unexpected event delayed the initiation of some of the research projects, still the main objectives of this joint, cross-disciplinary research effort were reached, and important insights were acquired for future, similar

    We examined familial bone mineral density (BMD) interactions between parents and children and lifestyle factors affecting BMD in the Korean general population of children under 20 and parents under 50 years of age. This cross-sectional study included 2,453 participants (667 daughters, 705 sons, 719 mothers, and 362 fathers) in the 2009-2010 Korean National Health and Nutrition Examination Survey. We calculated prevalence ratios and 95 % confidence intervals for BMD values of whole femur, femur neck, lumbar spine, and whole body excluding the head being in the low tertile in adolescents according to parental BMD tertile after adjusting for physical, lifestyle, and dietary factors. For daughters and sons, there were significant differences in BMD at the four bone sites according to age group, body fat percentage, regular walking and exercise, and milk consumption compared to the reference value for each classification category. Surprisingly, there were no differences in BMD according to serum 25-OH-D levels. Birth order affected BMD of only whole body except head, but its impact was less than that of lifestyle factors. The mean differences in BMD between daughters and sons in the first and third parental BMD tertiles were statistically significant. Notably, the prevalence ratio of whole body without head BMD being in the low tertile increased eight and ten-folds in adolescent daughters and sons, respectively, when parents were in the low BMD tertile. In specific bone regions, parental BMD had a greater effect on total femur in daughters but in the lumbar spine in sons. In conclusion, parental BMD positively influences BMD in daughters and sons after adjustment for environmental parameters. This suggests that the children from parents with low BMD need to make an extra effort to increase BMD through dietary and lifestyle changes.

    We present a study of horizontal winds in the mesosphere and lower thermosphere (MLT) during the boreal winters of 2009-2010 and 2012-2013 produced with a new high-altitude numerical weather prediction (NWP) system. This system is based on a modified version of the Navy Global Environmental Model (NAVGEM) with an extended vertical domain up to ∼116 km altitude coupled with a hybrid four-dimensional variational (4DVAR) data assimilation system that assimilates both standard operational meteorological observations in the troposphere and satellite-based observations of temperature, ozone and water vapor in the stratosphere and mesosphere. NAVGEM-based MLT analyzed winds are validated using independent meteor radar wind observations from nine different sites ranging from 69°N-67°S latitude. Time-averaged NAVGEM zonal and meridional wind profiles between 75 and 95 km altitude show good qualitative and quantitative agreement with corresponding meteor radar wind profiles. Wavelet analysis finds that the 3-hourly NAVGEM and 1-hourly radar winds both exhibit semi-diurnal, diurnal, and quasi-diurnal variations whose vertical profiles of amplitude and phase are also in good agreement. Wavelet analysis also reveals common time-frequency behavior in both NAVGEM and radar winds throughout the Northern extratropics around the times of major stratospheric sudden warmings (SSWs) in January 2010 and January 2013, with a reduction in semi-diurnal amplitudes beginning around the time of a mesospheric wind reversal at 60°N that precedes the SSW, followed by an amplification of semi-diurnal amplitudes that peaks 10-14 days following the onset of the mesospheric wind reversal. The initial results presented in this study demonstrate that the wind analyses produced by the high-altitude NAVGEM system accurately capture key features in the observed MLT winds during these two boreal winter periods.

    Alcoa began this program in March of 2008 with the goal of developing and validating an advanced CSP trough design to lower the levelized cost of energy (LCOE) as compared to existing glass based, space-frame trough technology. In addition to showing a pathway to a significant LCOE reduction, Alcoa also desired to create US jobs to support the emerging CSP industry. Alcoa's objective during Phase I: Concept Feasibility was to provide the DOE with a design approach that demonstrates significant overall system cost savings without sacrificing performance. Phase I consisted of two major tasks; reflector surface development and system concept development. Two specific reflective surface technologies were investigated, silver metallized lamination, and thin film deposition both applied on an aluminum substrate. Alcoa prepared samples; performed test validation internally; and provided samples to the NREL for full-spectrum reflectivity measurements. The final objective was to report reflectivity at t = 0 and the latest durability results as of the completion of Phase 1. The target criteria for reflectance and durability were as follows: (1) initial (t = 0), hemispherical reflectance >93%, (2) initial spectral reflectance >90% for 25-mrad reading and >87% for 7-mrad reading, and (3) predicted 20 year durability of less than 5% optical performance drop. While the results of the reflective development activities were promising, Alcoa was unable to down-select on a reflective technology that met the target criteria. Given the progress and potential of both silver film and thin film technologies, Alcoa continued reflector surface development activities in Phase II. The Phase I concept development activities began with acquiring baseline CSP system information from both CSP Services and the DOE. This information was used as the basis to develop conceptual designs through ideation sessions. The concepts were evaluated based on estimated cost and high-level structural

    Foodborne Yersinia enterocolitica infections continue to be a public health problem in many countries. Consumption of raw or undercooked pork is the main risk factor for yersiniosis in Germany. Small children are most frequently affected by yersiniosis. In older children and young adults, symptoms of disease may resemble those of appendicitis and may lead to hospitalization and potentially unnecessary appendectomies. Y. enterocolitica infections may also cause sequelae such as reactive arthritis (ReA), erythema nodosum (EN), and conjunctivitis. We studied clinical aspects of yersiniosis, antimicrobial use, and self-reported occurrence of appendectomies, reactive arthritis, erythema nodosum and conjunctivitis. To assess post-infectious sequelae participants of a large population-based case-control study on laboratory-confirmed Y. enterocolitica infections conducted in Germany in 2009-2010 were followed for 4 weeks. Diarrhea occurred most frequently in children ≤4 years (95%); abdominal pain in the lower right quadrant was most common in children 5-14 years of age (63%). Twenty-seven per cent of patients were hospitalized, 37% were treated with antimicrobials. In 6% of yersiniosis patients ≥5 years of age, appendectomies were performed. Self-reported symptoms consistent with ReA were reported by 12% of yersiniosis patients compared to 5% in a reference group not exposed to yersiniosis. Symptoms consistent with EN were reported by 3% of yersiniosis patients compared to 0.1% in the reference group. Symptoms of conjunctivitis occurred with the same frequency in yersiniosis patients and the reference group. Acute Y. enterocolitica infections cause considerable burden of illness with symptoms lasting for about 10 days and hospitalizations in more than a quarter of patients. The proportion of yersiniosis patients treated with antimicrobial drugs appears to be relatively high despite guidelines recommending their use only in severe cases. Appendectomies and post

    We examined prevalence of diagnosed autism spectrum disorder (ASD) and age at diagnosis according to child's race/ethnicity and primary household language. From the 2009-2010 National Survey of Children with Special Health Care Needs, we identified 2729 3-17-year-old US children whose parent reported a current ASD diagnosis. We compared ASD prevalence, mean diagnosis age, and percentage with later diagnoses (≥5 years) across racial/ethnic/primary household language groups: non-Hispanic-white, any language (NHW); non-Hispanic-black, any language (NHB); Hispanic-any-race, English (Hispanic-English); and Hispanic-any-race, other language (Hispanic-Other). We assessed findings by parent-reported ASD severity level and adjusted for family sociodemographics. ASD prevalence estimates were 15.3 (NHW), 10.4 (NHB), 14.1 (Hispanic-English), and 5.2 (Hispanic-Other) per 1000 children. Mean diagnosis age was comparable across racial/ethnic/language groups for 3-4-year-olds. For 5-17-year-olds, diagnosis age varied by race/ethnicity/language and also by ASD severity. In this group, NHW children with mild/moderate ASD had a significantly higher proportion (50.8 %) of later diagnoses than NHB (33.5 %) or Hispanic-Other children (18.0 %). However, NHW children with severe ASD had a comparable or lower (albeit non-significant) proportion (16.4 %) of later diagnoses than NHB (37.8 %), Hispanic-English (30.8 %), and Hispanic-Other children (12.0 %). While NHW children have comparable ASD prevalence and diagnosis age distributions as Hispanic-English children, they have both higher prevalence and proportion of later diagnoses than NHB and Hispanic-Other children. The diagnosis age findings were limited to mild/moderate cases only. Thus, the prevalence disparity might be primarily driven by under-representation (potentially under-identification) of older children with mild/moderate ASD in the two minority groups.

Method: Data from Global Adult Tobacco Survey 2009-2010 was analyzed using methods for complex (clustered sample designs. Multivariate logistic regression was employed to predict the use of different tobacco products by level of exposure to tobacco marketing using adults who have never used tobacco as the reference category. Odds ratios (ORs were adjusted for education, gender, age, state of residence, wealth index, and place of residence (urban/rural. Results: Adults in India were almost twice as likely to be current smokers (versus never users when they were exposed to a moderate level of bidi or cigarette marketing. For bidis, among adults with high exposure, the OR for current use was 4.57 (95% confidence interval [CI]: 1.6, 13.0. Adults were more likely to be current users of smokeless tobacco (SLT with even a low level of exposure to SLT marketing (OR = 1.24 [95% CI: 1.1, 1.4]. For SLT, the ORs showed an increasing trend (P for trend < 0.001 with greater level of exposure (moderate, OR = 1.55 [95% CI: 1.1, 2.2]; high, OR = 2.05 [95% CI: 0.8, 5.1]. The risk of any current tobacco use rose with increasing level of exposure to any marketing (minimum, OR = 1.25 [1.1-1.4]; moderate, OR = 1.38 [1.1-1.8]; and high, OR = 2.73 [1.8-4.2], with the trend highly significant (P < 0.001. Conclusion: Exposure to the marketing of tobacco products, which may take the form of advertising at the point of sale, sales or a discounted price, free coupons, free samples, surrogate advertisements, or any of several other modalities, increased prevalence of tobacco use among adults. An increasing level of exposure to direct and indirect advertisement and promotion is

    The regeneration of chromium (VI) and the recovery of etched copper from chromium etching solutions by electrodialysis is improved by the addition of a concentrator cell in the catholyte chamber. The concentrator media used are ion-exchange resins or activated carbon cloth. The maximum percentages for the regeneration of chromium and recovery of copper in these systems is however less than 80% and 90% respectively because of the competition between the processes of oxidation of Cr(III) and electrodeposition of copper. A novel combination of electrolysis with electrodialysis and concentrator cell technology is developed that achieves 92% chromium regeneration and 90% copper recovery.

    Alcoa began this program in March of 2008 with the goal of developing and validating an advanced CSP trough design to lower the levelized cost of energy (LCOE) as compared to existing glass based, space-frame trough technology. In addition to showing a pathway to a significant LCOE reduction, Alcoa also desired to create US jobs to support the emerging CSP industry. Alcoa's objective during Phase I: Concept Feasibility was to provide the DOE with a design approach that demonstrates significant overall system cost savings without sacrificing performance. Phase I consisted of two major tasks; reflector surface development and system concept development. Two specific reflective surface technologies were investigated, silver metallized lamination, and thin film deposition both applied on an aluminum substrate. Alcoa prepared samples; performed test validation internally; and provided samples to the NREL for full-spectrum reflectivity measurements. The final objective was to report reflectivity at t = 0 and the latest durability results as of the completion of Phase 1. The target criteria for reflectance and durability were as follows: (1) initial (t = 0), hemispherical reflectance >93%, (2) initial spectral reflectance >90% for 25-mrad reading and >87% for 7-mrad reading, and (3) predicted 20 year durability of less than 5% optical performance drop. While the results of the reflective development activities were promising, Alcoa was unable to down-select on a reflective technology that met the target criteria. Given the progress and potential of both silver film and thin film technologies, Alcoa continued reflector surface development activities in Phase II. The Phase I concept development activities began with acquiring baseline CSP system information from both CSP Services and the DOE. This information was used as the basis to develop conceptual designs through ideation sessions. The concepts were evaluated based on estimated cost and high-level structural

    The economies-of-scale and enhanced performance of integrated micro-technologies have repeatedly delivered disruptive market impact. Examples range from microelectronics to displays to lighting. However, integrated micro-scale technologies have yet to be applied in a transformational way to solar photovoltaic panels. The recently announced Micro-scale Optimized Solar-cell Arrays with Integrated Concentration (MOSAIC) program aims to create a new paradigm in solar photovoltaic panel technology based on the incorporation of micro-concentrating photo-voltaic (μ-CPV) cells. As depicted in Figure 1, MOSAIC will integrate arrays of micro-optical concentrating elements and micro-scale PV elements to achieve the same aggregated collection area and high conversion efficiency of a conventional (i.e., macro-scale) CPV approach, but with the low profile and mass, and hopefully cost, of a conventional non-concentrated PV panel. The reduced size and weight, and enhanced wiring complexity, of the MOSAIC approach provide the opportunity to access the high-performance/low-cost region between the conventional CPV and flat-plate (1-sun) PV domains shown in Figure 2. Accessing this portion of the graph in Figure 2 will expand the geographic and market reach of flat-plate PV. This talk reviews the motivation and goals for the MOSAIC program. The diversity of the technical approaches to micro-concentration, embedded solar tracking, and hybrid direct/diffuse solar resource collection found in the MOSAIC portfolio of projects will also be highlighted.

    The 2009-2010 period was marked by an episode of intense drought known as the El Niño Modoki event. Sampling of the Términos Lagoon (Mexico) was carried out in November 2009 in order to understand the influence of these particular environmental conditions on organic matter fluxes within the lagoon's pelagic ecosystem and, more specifically, on the relationship between phyto- and bacterioplankton communities. The measurements presented here concern biogeochemical parameters (nutrients, dissolved and particulate organic matter [POM], and dissolved polycyclic aromatic hydrocarbons [PAHs]), phytoplankton (biomass and photosynthesis), and bacteria (diversity and abundance, including PAH degradation bacteria and ectoenzymatic activities). During the studied period, the water column of the Términos Lagoon functioned globally as a sink and, more precisely, as a nitrogen assimilator. This was due to the high production of particulate and dissolved organic matter (DOM), even though exportation of autochthonous matter to the Gulf of Mexico was weak. We found that bottom-up control accounted for a large portion of the variability of phytoplankton productivity. Nitrogen and phosphorus stoichiometry mostly accounted for the heterogeneity in phytoplankton and free-living prokaryote distribution in the lagoon. In the eastern part, we found a clear decoupling between areas enriched in dissolved inorganic nitrogen near the Puerto Real coastal inlet and areas enriched in phosphate (PO4) near the Candelaria estuary. Such a decoupling limited the potential for primary production, resulting in an accumulation of dissolved organic carbon and nitrogen (DOC and DON, respectively) near the river mouths. In the western part of the lagoon, maximal phytoplankton development resulted from bacterial activity transforming particulate organic phosphorus (PP) and dissolved organic phosphorus (DOP) to available PO4 and the coupling between Palizada River inputs of nitrate (NO3) and PP.

    Comparison of the viral persistence of pandemic H1N1 (H1N1pdm) and seasonal H1N1 with or without H275Y mutation after oseltamivir therapy has not been adequately done. Virus was isolated before and on days 4-6 from the start of oseltamivir treatment for 158 cases of seasonal (2007-2008 and 2008-2009 seasons) or pandemic (2009-2010 season) H1N1 influenza. Sequence analysis was done for each season and NA inhibition assay (IC(50)) was done in the 2009-2010 season. H275Y mutation before therapy was 0% in the 2007-2008 and 2009-2010 seasons, but 100% in the 2008-2009 season. Fever and other symptoms were noticeably prolonged after oseltamivir therapy for children with H275Y mutated seasonal H1N1 (2008-2009 season), but not in patients with seasonal H1N1 without mutation (2007-2008) or H1N1pdm (2009-2010). The viral persistence rate was significantly higher for patients 15 years or younger than for those 16 years and older with H275Y mutated seasonal H1N1 (46.2% and 10.5%, respectively) or with H1N1pdm (43.3% and 11.5%, respectively). The H275Y mutation emerged after oseltamivir treatment in 2.4% (2/82) of all patients with H1N1pdm. In two children, the H275Y mutation emerged after therapy and the IC(50) increased more than 200 fold; however, the prolongation of fever was not so prominent. In conclusion, oseltamivir was effective for fever and other clinical symptoms; however, the virus persisted longer than expected after treatment in H1N1pdm influenza-infected children in the 2009-2010 season, similar to seasonal H1N1 with H275Y mutation in the 2008-2009 season.

  8. Less-studied TCE: are their environmental concentrations increasing due to their use in new technologies?

    Filella, M; Rodríguez-Murillo, J C

    2017-09-01

    The possible environmental impact of the recent increase in use of a group of technology-critical elements (Nb, Ta, Ga, In, Ge and Te) is analysed by reviewing published concentration profiles in environmental archives (ice cores, ombrotrophic peat bogs, freshwater sediments and moss surveys) and evaluating temporal trends in surface waters. No increase has so far been recorded. The low potential direct emissions of these elements, resulting from their absolute low production levels, make it unlikely that the increasing use of these elements in modern technology has any noticeable effect on their environmental concentrations on a global scale. This holds particularly true for those of these elements that are probably emitted in relatively high amounts from other human activities (i.e., coal combustion and non-ferrous smelting), such as In, the most studied element of the group.

    2010-01-01

    In coal mines in such countries as China and Russia,most of the coal mine methane(CMM) generated during mining is emitted to the atmosphere without any effective usage,because the methane concentration of CMM is relatively low and not allowed to be used as fuel for safety reasons.Methane is one of the greenhouse gases.Therefore,if it becomes possible to concentrate CMM to an acceptable level for use as fuel,this will greatly contribute to reduction of greenhouse gas emissions.With the aim of gaining approval as a greenhouse gas emission reduction of the clean development mechanism(CDM) or joint implementation(JI) project,we developed a CMM concentration system to apply the vacuum pressure swing adsorption(VPSA) technology using a high methane-selective adsorbent by Osaka Gas Co.,Ltd.The pilot-scale plant of a CMM concentration system was installed in a coal mine in Fuxin City in the northeastern China and a demonstration test was commenced in December 2008.As the result,the pilot-scale plant successfully concentrated the raw material gas with a methane concentration of 21% and a flow rate of 1000 Nm3/h to 48%,which exceeded the target of the methane concentration performance(a 25% increase).The methane recovery rate reached 93%.

    Concentrated runoff increases erosion and efficiently transfers sediment and associated agrichemicals from upland areas to stream channels. Ephemeral gully erosion on cropland in the U.S. may contribute 40% of the sediment delivered to the edge of the field. Typically, conservation practices developed for sheet and rill erosion are also expected to treat ephemeral gully erosion, but technology and tools do not exist to account for the separate benefits and effects of practices on various sediment sources. Practices specifically developed to treat ephemeral gully erosion need further testing, when used in conjunction with sheet and rill erosion control practices. Without improved research studies, subjective observations will continue to be used to satisfy quality criteria in lieu of scientifically defensible, quantitative methods to estimate the impact of gully erosion. Some of the more important limiting components are the identification of and relationships for: (1) ephemeral gully width; (2) soil resistance to gully erosion including a definition for non-erosive layers; (3) the effect of root mass and above ground vegetation on erosion resistance; (4) ephemeral gully networks; and (5) the effect of subsurface flow on ephemeral gullies. Currently, these components are represented through widely divergent to non-existent algorithms. The U.S. Department of Agriculture's AnnAGNPS pollutant loading model has been developed to determine the effects of conservation management plans and provide sediment tracking from all sources within the watershed, including ephemeral gullies. Enhanced technology is also needed to identify where ephemeral gullies may form in the watershed using remote sensing technology. Developing enhanced technology and research for concentrated flow assessments is critical for developing and testing conservation practices specifically designed for gully erosion control. This study will describe the current state of concentrated flow assessment and

    Concentrating photovoltaic (CPV) technology recently gained interest based on its expected low levelized cost of electricity, high efficiency, and scalability. Many CPV systems employ Fresnel lenses composed of poly(methyl methacrylate) (PMMA) to obtain a high optical flux density on the cell. The optical and mechanical durability of these lenses, however, is not well established relative to the desired surface life of 30 years. Our research aims to quantify the expected lifetime of PMMA in key market locations (FL, AZ, and CO).

    Study of drought process which is a gradual change is helpful to understand disaster mechanism and offer basis for disaster risk prevention. This paper was based on the literature review and questionnaire and interview methods. This paper chose Yunnan Province drought which mainly happened in 2010 as the study case, and constructed evolution sequence of dry grade, as well as the disaster response sequence of the government, the whole social groups, social organizations and victims in 2009 -2010 on the basis of daily meteorological monitoring data, daily drought-related reports on newspapers and periodicals, as well as home-interviews from victims. By comparison and analysis, the results are as follows: the meteorological drought continued severe drought for a long time that from the autumn to the spring of next year. Compared with the meteorological drought evolution, the process of disaster response of social subjects is basically the same in development trend, which both have the complete cycle that from start, continued to strengthen, finally to reduce. However, in time series, the response lag of disaster response to disaster is obvious, which present obvious lag at early drought and basic synchronization at the final. The disaster behaviors of different subjects are different in timing and strength. The victim's disaster behavior lasted the longest time, and focused on searching and conserving water. The government department's disaster behavior is the most centralized and efficient, and put emphasis on drought-resistant guidance and deployment. According to the a-bove characteristics, we put forward some suggestions to improve the efficiency of social response to disaster, such as strengthening timeliness of meteorological monitoring and warning, and also of the media propaganda; improve the ability of victims' response to disaster.%旱灾作为渐发性灾害,社会应灾的过程研究有助于理解成灾机制,但“过程”量化方法有待探讨.应

    Rapid and real-time analysis of cigarette smoke is of great significance to study the puff-by-puff transfer rules in the suction process and to explore the relationship between smoking and health. By combining with the modified commercial smoking machine herein, cigarette smoke online analysis system was established based on the TDLAS technology. The puff-by-puff stability of this system was verified by simulated cigarette composed of a pocket containing CH₄ (volume fraction of 0.4), of which the second harmonic peaks are near 1.39. Using this system, the concentration of CH₄ in four different kinds of cigarettes was analyzed puff-by-puff by a semiconductor laser, of which center wavelength was at 1 653.72 nm. The results showed that the CH₄ concentration of cigarette smoke increased puff-by-puff. CH₄ concentration in the flue-cured cigarette is obviously higher than that of blended cigarette by comparing the content of all and puff-by-puff concentration. The puff-by-puff concentration of flue-cured cigarette increased from 400 to 900 ppm, however, the puff-by-puff concentration of blended cigarette increased from 200 to 600 ppm. Simultaneously, there was significant difference between different kinds of the flue-cured. Comparing to tradi- tional analysis methods, this system can effectively avoid the interference of other gases in the smoke cigarette as a result of its strong anti-interference. At the same time, it can finish analysis between suction interval without sample pretreatment. The technology has a good prospect in the online puff-by-puff analysis of cigarette smoke.

    This study fills demand for data on access and use of information and communication technologies (ICT) in the Brazilian legal Amazon, a region of localities with identical economic, political, and social problems. We use the 2010 Brazilian Demographic Census to compile data on urban and rural households (i) with computers and Internet access, (ii) with mobile phones, and (iii) with fixed phones. To compare the concentration of access to ICT in the municipalities of the Brazilian Amazon with other regions of Brazil, we use a concentration index to quantify the concentration of households in the following classes: with computers and Internet access, with mobile phones, with fixed phones, and no access. These data are analyzed along with municipal indicators on income, education, electricity, and population size. The results show that for urban households, the average concentration in the municipalities of the Amazon for computers and Internet access and for fixed phones is lower than in other regions of the country; meanwhile, that for no access and mobile phones is higher than in any other region. For rural households, the average concentration in the municipalities of the Amazon for computers and Internet access, mobile phones, and fixed phones is lower than in any other region of the country; meanwhile, that for no access is higher than in any other region. In addition, the study shows that education and income are determinants of inequality in accessing ICT in Brazilian municipalities and that the existence of electricity in rural households is directly associated with the ownership of ICT resources.

Under this project we prepared a detailed description of our current manufacturing process for making our unique linear Fresnel lens photovoltaic concentrator modules. In addition, we prepared a detailed description of an improved manufacturing process, which will simultaneously increase module production rates, enhance module quality, and substantially reduce module costs. We also identified potential problems in implementing the new manufacturing process, and we proposed solutions to these anticipated problems. Before discussing the key results of our program, however, we present a brief description of our unique photovoltaic technology. The key conclusion of our PVMAT Phase 1 study is that our module technology, without further breakthroughs, can realistically meet the near-term DOE goal of 12 cents/kWh levelized electricity cost, provided that we successfully implement the new manufacturing process at a production volume of at least 10 megawatts per year. The key recommendation from our Phase 1 study is to continue our PVMaT project into Phase 2A, which is directed toward the actual manufacturing technology development required for our new module production process. 15 refs.

    Full Text Available Among solar power generation, concentrated photovoltaics (CPV based on multijunction (MJ solar cells, is one of the most promising technology for hot climates. The fact that multijunction solar cells based on direct band gap semiconductors demonstrate lower dependence on temperature than silicon solar cells boosted their use in concentrated photovoltaics modules. Departing from the mainstream design of Fresnel lenses, the CPV module based on TwinFocus design with off-axis quasi parabolic mirrors differentiates itself for its compactness and the possibility of easy integration also in roof-top applications. A detailed description of the module and of the systems will be given together with measured performances, and expectations for the next release.

    Full Text Available Introduction. Due to the fact that the production of microbial surfactants is limited by the low yield of end products and high cost of processes, the actual task is to optimize and reduce the cost of the technology of biosurfactants synthesis. One of the solutions of this problem is to use the industrial wastes, including rape phosphatide concentrate (PC. Materials and methods. Hexadecane and rape phosphatide concentrate (2% were used as a carbon source in a nutrient medium for the cultivation of bacteria. Lipids were extracted from a cell mass and supernatant by the mixture of chloroform-methanol 2:1. The qualitative analysis of metabolites was performed by a thin layer chromatography. Results and discussion. The peculiarities of synthesis of biosurfactants by strains G. rubripertincta UCM Aс-122 and R. erythropolis Au-1 during the growth on the nutrient media with rape phosphatide concentrate as a carbon source was studied. Quantity of biomass was 9.4 – 10.1 g/l, exopoly mers –8.9-9.5 g/l and the content of cellbound trehalose lipids was 1.37 – 2.26 g/l; whereas the content of exogenous trehalose lipids –metabolites of R. erythropolis Au-1 was 2.95 g/l. It was found that the addition of trehalose lipids (0.01 g/l to the nutrient medium caused the increase of biomass on 14.6 –17.0 % and cell-bound lipids on 13.9 –15.5 %. Conclusions. Rape phosphatide concentrate is economically viable carbon source in the technologies of surfactant production by Actinobacteria. Its use promotes an increasing of exogenous surfactants strain R. erythropolisAu-1 in 3-fold compared with cultivation on nutrient medium with hexadecane. Trehalose lipids show a stimulating effect on growth and synthesis of biosurfactants by strains of G. rubripertincta UCM Ac-122 and R. erythropolisAu-1.

    A flight experiment has demonstrated a modular solar concentrator that can be used as a direct substitute replacement for planar photovoltaic panels in spacecraft solar arrays. The Light Concentrating Panel (LCP) uses an orthogrid arrangement of composite mirror strips to form an array of rectangular mirror troughs that reflect light onto standard, high-efficiency solar cells at a concentration ratio of approximately 3:1. The panel area, mass, thickness, and pointing tolerance has been shown to be similar to a planar array using the same cells. Concentration reduces the panel's cell area by 2/3, which significantly reduces the cost of the panel. An opportunity for a flight experiment module arose on NASA's Small Explorer / Wide-Field Infrared Explorer (SMEX/WIRE) spacecraft, which uses modular solar panel modules integrated into a solar panel frame structure. The design and analysis that supported implementation of the LCP as a flight experiment module is described. Easy integration into the existing SMEX-LITE wing demonstrated the benefits of technology transparency. Flight data shows the stability of the LCP module after nearly one year in Low Earth Orbit.

    The relationship between risk of death following influenza A(H1N1)pdm09 infection and ethnicity and deprivation during the 2009/2010 pandemic period and the first post-pandemic season of 2010/2011 in England was examined. Poisson regression models were used to estimate the mortality risk, adjusted for age, gender, and place of residence. Those of non-White ethnicity experienced an increased mortality risk compared to White populations during the 2009/2010 pandemic [10·5/1000 vs. 6·0/1000 general population; adjusted risk ratio (RR) 1·84, 95% confidence interval (CI) 1·39-2·54] with the highest risk in those of Pakistani ethnicity. However, no significant difference between ethnicities was observed during the following 2010/2011 season. Persons living in areas with the highest level of deprivation had a significantly higher risk of death (RR 2·08, 95% CI 1·49-2·91) compared to the lowest level for both periods. These results highlight the importance of rapid identification of groups at higher risk of severe disease in the early stages of future pandemics to enable the implementation of optimal prevention and control measures for vulnerable populations.

    Over the last several years, solar energy technologies have been, or are in the process of being, deployed at unprecedented levels. A critical recent development, resulting from the massive scale of projects in progress or recently completed, is having the power sold directly to electric utilities. Such 'utility-scale' systems offer the opportunity to deploy solar technologies far faster than the traditional 'behind-the-meter' projects designed to offset retail load. Moreover, these systems have employed significant economies of scale during construction and operation, attracting financial capital, which in turn can reduce the delivered cost of power. This report is a summary of the current U.S. utility-scale solar state-of-the-market and development pipeline. Utility-scale solar energy systems are generally categorized as one of two basic designs: concentrating solar power (CSP) and photovoltaic (PV). CSP systems can be further delineated into four commercially available technologies: parabolic trough, central receiver (CR), parabolic dish, and linear Fresnel reflector. CSP systems can also be categorized as hybrid, which combine a solar-based system (generally parabolic trough, CR, or linear Fresnel) and a fossil fuel energy system to produce electric power or steam.

    Full Text Available Concentrated solar power (CSP systems can play a major role as a renewable energy source with the inherent possibility of including a thermal energy storage subsystem for improving the plant dispatchability. Next-generation CSP systems have to provide an increased overall efficiency at reduced specific costs and they will require higher operating temperatures and larger heat flux densities. In that context, liquid metals are proposed as advanced high temperature heat transfer fluids, particularly for central receiver systems. Their main advantages are chemical stability at temperatures up to 900 ℃ and even beyond, as well as largely improved heat transfer when compared to conventional fluids like oil or salt mixtures, primarily due to their superior thermal conductivity. However, major issues here are the corrosion protection of structural materials and the development of technology components and control systems, as well as the development of indirect storage solutions, to circumvent the relatively small heat capacity of liquid metals. On the other hand, using liquid metals might enable alternative technologies like direct thermal-electric conversion or use of solar high-tem­perature heat in chemical processes. This article aims at describing research areas and research needs to be addressed for fully evaluating and subsequently utilizing the potential of liquid metals in CSP systems. A second aim of the article is a brief overview of the liquid metal research capabilities of Karlsruhe Institute of Technology (KIT, their background and their relation to CSP and the aforementioned research pathways.

    Sports-related concussions (SRCs) have gained increased societal interest in the past decade. The National Collegiate Athletic Association (NCAA) has implemented legislation and rule changes to decrease the incidence and risk of head injury impacts. The "targeting" rule forbids initiating contact with the crown of a helmet and targeting defenseless players in the head and neck area; however, there are concerns that this rule change has unintentionally led to an increased incidence of lower extremity injuries. The purpose of this study was to evaluate the change in lower extremity injury rates in NCAA football during the 2009-2010 to 2014-2015 seasons. We hypothesized that the lower extremity injury rate has increased across the time period. Descriptive epidemiology study. Sixty-eight NCAA football programs provided 153 team-seasons of data to the NCAA Injury Surveillance Program. Lower extremity injuries (ie, hip/groin, upper leg/thigh, knee, lower leg/Achilles, foot/toes) and SRCs sustained during NCAA football games were examined. We calculated injury rates per 1000 athlete-exposures (AEs) for lower extremity injuries and SRCs. Rate ratios (RRs) compared injury rates between the 2009-2010 to 2011-2012 and 2012-2013 to 2014-2015 seasons. Overall, 2400 lower extremity injuries were reported during the 2009-2010 to 2014-2015 seasons; most were to the knee (33.6%) and ankle (28.5%) and caused by player contact (59.2%). The lower extremity injury rate increased in 2012-2013 to 2014-2015 compared with 2009-2010 to 2011-2012 (23.55 vs 20.45/1000 AEs, respectively; RR, 1.15; 95% CI, 1.06-1.25). This finding was retained when restricted to injuries due to player contact (RR, 1.19; 95% CI, 1.07-1.32) but not for injuries due to noncontact/overuse (RR, 0.96; 95% CI, 0.80-1.14). When examining player contact injury rates by anatomic site, only ankle injuries had an increase (RR, 1.36; 95% CI, 1.13-1.64). The SRC rate also increased in 2012-2013 to 2014-2015 compared with

    Full Text Available Abstract Background Exposure to persistent organic pollutants, including polychlorinated biphenyls (PCBs and organochlorine pesticides, is widespread among the general population. There is evidence of adverse effects on reproduction and early pregnancy in relation to organochlorine exposure but human studies remain limited. The increased use of assisted reproductive technologies (ART presents unique opportunities for the assessment of environmental influences on early pregnancy outcomes not otherwise observable in humans, but studies need to be designed to maximize the efficiency of the exposure data collected while minimizing exposure measurement error. Methods The present study was conducted to assess the correlation between concentrations of organochlorines in serum and follicular fluid samples collected from a subset of women undergoing ART in a large study that took place between 1994 and 2003, as well as the temporal reliability of serum organochlorine concentrations among women undergoing multiple ART cycles in the study. PCB congeners (118, 138, 153, and 180, 1,1,1-trichloro-2,2-bis(p-chlorophenylethane (p,p'-DDT, the DDT metabolite p,p'-DDE, hexachlorobenzene (HCB, oxychlordane, trans-nonachlor and mirex were measured in 72 follicular fluid samples and 265 serum samples collected from 110 women. Results Organochlorine concentrations in paired serum and follicular fluid samples were correlated, with Pearson and Spearman coefficients ranging from 0.60 to 0.92. Serum organochlorine concentrations were two- to three-fold greater than in follicular fluid, and a significant inverse trend was observed in the distribution of follicular fluid:serum ratios with increasing molecular weight of the compound (p-value for trend Conclusion Our results support the use of a single serum sample to adequately represent a more biologically relevant dose (concentrations in follicular fluid, as well as exposure levels over time, in epidemiological studies of

    Full Text Available This study fills demand for data on access and use of information and communication technologies (ICT in the Brazilian legal Amazon, a region of localities with identical economic, political, and social problems. We use the 2010 Brazilian Demographic Census to compile data on urban and rural households (i with computers and Internet access, (ii with mobile phones, and (iii with fixed phones. To compare the concentration of access to ICT in the municipalities of the Brazilian Amazon with other regions of Brazil, we use a concentration index to quantify the concentration of households in the following classes: with computers and Internet access, with mobile phones, with fixed phones, and no access. These data are analyzed along with municipal indicators on income, education, electricity, and population size. The results show that for urban households, the average concentration in the municipalities of the Amazon for computers and Internet access and for fixed phones is lower than in other regions of the country; meanwhile, that for no access and mobile phones is higher than in any other region. For rural households, the average concentration in the municipalities of the Amazon for computers and Internet access, mobile phones, and fixed phones is lower than in any other region of the country; meanwhile, that for no access is higher than in any other region. In addition, the study shows that education and income are determinants of inequality in accessing ICT in Brazilian municipalities and that the existence of electricity in rural households is directly associated with the ownership of ICT resources.

    Feng Feng

    Full Text Available Surface plasmon resonance (SPR has previously been employed to measure the active concentration of analyte in addition to the kinetic rate constants in molecular binding reactions. Those approaches, however, have a few restrictions. In this work, a Bayesian approach is developed to determine both active concentration and affinity constants using SPR technology. With the appropriate prior probabilities on the parameters and a derived likelihood function, a Markov Chain Monte Carlo (MCMC algorithm is applied to compute the posterior probability densities of both the active concentration and kinetic rate constants based on the collected SPR data. Compared with previous approaches, ours exploits information from the duration of the process in its entirety, including both association and dissociation phases, under partial mass transport conditions; do not depend on calibration data; multiple injections of analyte at varying flow rates are not necessary. Finally the method is validated by analyzing both simulated and experimental datasets. A software package implementing our approach is developed with a user-friendly interface and made freely available.

    Market diffusion of flat plate crystalline silicon photovoltaic (PV) technology has been induced by economical support schemes and has lead to reduced cost per produced kWh electricity. For further market penetration of the PV technology, a continued reduction of production cost is required. Two alternative approaches to achieve this are using less expensive materials or changing the active materials. The technologies of concentrator PV (CPV) systems and polymer PV (PPV) devices represent these two strategies. The potential energy performance of these technologies is studied in terms of the process primary energy requirements for manufacturing, how many times this energy is paid back during its lifetime and as the required land area for electricity generation. The study is an energy analysis incorporating the inherent uncertainties in technology development. Uncertainties are identified in data acquisition, in design choices, as induced by development and improvement, in performance and by different application scenarios. The future technology alternatives are defined in different ways for CPV and PPV. CPV parameters are derived from existing products and ideas for improvements and PPV parameters from the directions of research. This study shows that the invested energy in future CPV and PPV is potentially paid back up to about 90 and 170 times, respectively, under Arizona (CPV) and average European (PPV) solar irradiation conditions. However the result is highly dependent on configuration, inventory data and device performance. Thus, for certain design alternatives, data and performance, PPV production energy is far from paid back during its lifetime. For CPV the energy return factor is decreased to about 13 in the least beneficial case. Area efficiency is studied as the land area requirements for producing a net output electricity of 1 MWh during 25 years. With device efficiencies from 1 to 5 per cent and lifetimes from 1 to 5 years a PPV device requires from 2

    Recent years witnessed a sharp increase of CSP (concentrated solar power) plants around the world. CSP is currently at its early stage in China, with several demonstration and utility-scale plants underway. China's rising electricity demand, the severe environmental pollution from coal-fired power...... plants, and favorable renewable energy policies are expected to result in a large-scale CSP deployment in the next years. Detailed CSP studies for China are however hardly available. To fill this knowledge gap, this study collects plant-specific data in a national CSP database in collaboration with local...... CSP experts. On this basis, this study analyzes and benchmarks the costs of parabolic trough CSP, tower CSP, and dish CSP technologies in China by applying an LCOE (levelized cost of electricity) model. The current LCOE for the different CSP plants falls in a range of 1.2-2.7 RMB/kWh (0.19-0.43 US...

    Goran Nikolić

    2013-11-01

    Full Text Available At the beginning of the 21st century there was a tendency of mild improvement of the quality of exports of Balkan countries, which can be traced through a slight increase in the share of goods of higher levels of processing (skill-intensive manufactures and medium- and high-tech products. In spite of that, the quality level of exports from Balkan economies lags greatly behind the countries in the EU and to a lesser extent the Central European economies in transition, with some signs of catching-up over time. The stagnant and relatively high levels of Export concentration ratio and low share of high processing goods are indicating that Balkan economies are increasingly specializing in price-sensitive markets.For export success it is of great importance to have the transfer of modern technology and investment, especially FDI, in competitive sectors which would 'spread' export offer. Improved approach to employment policy regulations and an extensive re-organization of science and education system is needed. One of the reasons for Balkan countries’ weak export lies in industrial policy, which would be able to promote innovation, product quality and high technological standards.

    Limited data exist among collegiate student-athletes on the epidemiology of sports-related concussion (SRC) outcomes, such as symptoms, symptom resolution time, and return-to-play time. This study used the National Collegiate Athletic Association (NCAA) Injury Surveillance Program (ISP) to describe the epidemiology of SRC outcomes in 25 collegiate sports. Descriptive epidemiology study. SRC data from the NCAA ISP during the 2009-2010 to 2013-2014 academic years were analyzed regarding symptoms, time to resolution of symptoms, and time to return to play. Findings were also stratified by sex in sex-comparable sports (ie, ice hockey, soccer, basketball, lacrosse, baseball/softball) and whether SRCs were reported as recurrent. Of the 1670 concussions reported during the 2009-2010 to 2013-2014 academic years, an average (±SD) of 5.29 ± 2.94 concussion symptoms were reported, with the most common being headache (92.2%) and dizziness (68.9%). Most concussions had symptoms resolve within 1 week (60.1%); however, 6.2% had a symptom resolution time of over 4 weeks. Additionally, 8.9% of concussions required over 4 weeks before return to play. The proportion of SRCs that required at least 1 week before return to play increased from 42.7% in 2009-2010 to 70.2% in 2013-2014 (linear trend, P concussions in male athletes included amnesia and disorientation; a larger proportion of concussions in female athletes included headache, excess drowsiness, and nausea/vomiting. A total of 151 SRCs (9.0%) were reported as recurrent. The average number of symptoms reported with recurrent SRCs (5.99 ± 3.43) was greater than that of nonrecurrent SRCs (5.22 ± 2.88; P = .01). A greater proportion of recurrent SRCs also resulted in a long symptom resolution time (14.6% vs 5.4%, respectively; P concussion management practices in which team medical staff members withhold players from participation longer to ensure symptom resolution.

    Soil gas and soil were assessed for contaminants at the South Prong Creek Disposal Area at Fort Gordon, Georgia, from October 2009 to September 2010. The assessment included identifying and delineating organic contaminants present in soil-gas and inorganic contaminants present in soil samples collected from the area estimated to be the South Prong Creek Disposal Area, including two seeps and the hyporheic zone. This assessment was conducted to provide environmental contamination data to Fort Gordon personnel pursuant to requirements for the Resource Conservation and Recovery Act Part B Hazardous Waste Permit process. All soil-gas samplers in the two seeps and the hyporheic zone contained total petroleum hydrocarbons above the method detection level. The highest total petroleum hydrocarbon concentration detected from the two seeps was 54.23 micrograms per liter, and the highest concentration in the hyporheic zone was 344.41 micrograms per liter. The soil-gas samplers within the boundary of the South Prong Creek Disposal Area and along the unnamed road contained total petroleum hydrocarbon mass above the method detection level. The highest total petroleum hydrocarbon mass detected was 147.09 micrograms in a soil-gas sampler near the middle of the unnamed road that traverses the South Prong Creek Disposal Area. The highest undecane mass detected was 4.48 micrograms near the location of the highest total petroleum hydrocarbon mass. Some soil-gas samplers detected undecane mass greater than the method detection level of 0.04 micrograms, with the highest detection of toluene mass of 109.72 micrograms in the same location as the highest total petroleum hydrocarbon mass. Soil-gas samplers installed in areas of high contaminant mass had no detections of explosives and chemical agents above their respective method detection levels. Inorganic concentrations in five soil samples did not exceed regional screening levels established by the U.S. Environmental Protection Agency

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    Research on quantitative models of suspended sediment concentration (SSC) using remote sensing technology is very important to understand the scouring and siltation variation in harbors and water channels. Based on laboratory study of the relationship between different suspended sediment concentrations and reflectance spectra measured synchronously, quantitative inversion models of SSC based on single factor, band ratio and sediment parameter were developed, which provides an effective method to retrieve the SSC from satellite images. Results show that the b1 (430-500nm) and b3 (670-735nm) are the optimal wavelengths for the estimation of lower SSC and the b4 (780-835nm) is the optimal wavelength to estimate the higher SSC. Furthermore the band ratio B2/B3 can be used to simulate the variation of lower SSC better and the B4/B1 to estimate the higher SSC accurately. Also the inversion models developed by sediment parameters of higher and lower SSCs can get a relatively higher accuracy than the single factor and band ratio models.

    Full Text Available Yacon is a perennial plant originating from the Andean region whose roots have been receiving increased att ention due to their high content of prebiotic fructooligosaccharides (FOS. Apart from many health benefi ts, FOS have interesting characteristics as food ingredients, so are used as sugar substitute, and their extraction from yacon roots may be an alternative to commercially available FOS. This work evaluates membrane technology for concentration and purifi cation of FOS from yacon root extract, combining ultrafiltration (UF with nanofi ltration (NF, with and without the use of discontinuous diafi ltration (DF. After UF, 63.75 % of the saccharides from the initial feed were recovered in total permeate. DF did not largely infl uence FOS retention during NF (it increased from 68.78 % without DF to 70.48 % with DF, but decreased glucose and fructose retentions, from 40.63 to 31.61 % and 25.64 to 18.69 %, respectively, which was desirable, allowing greater purification of FOS in the retentate. The yield of total saccharides in the final retentate after combined UF and NF processes was 50.89 % and of FOS was 51.85 %, with 19.75 % purity. The results indicate that the combined UF and NF is a promising technique for concentrating yacon saccharides, but more diafi ltration steps are required for the improvement of FOS purity.

    Soil gas and soil were assessed for contaminants at the Old Metal Workshop Hog Farm Area at Fort Gordon, Georgia, from October 2009 to September 2010. The assessment included delineating organic contaminants present in soil-gas and inorganic contaminants present in soil samples collected from the area estimated to be the Old Metal Workshop Hog Farm Area. This assessment was conducted to provide environmental contamination data to Fort Gordon personnel pursuant to requirements for the Resource Conservation and Recovery Act Part B Hazardous Waste Permit process. All soil-gas samplers contained total petroleum hydrocarbons above the method detection level. The highest total petroleum hydrocarbon mass detected was 121.32 micrograms in a soil-gas sampler from the western corner of the Old Metal Workshop Hog Farm Area along Sawmill Road. The highest undecane mass detected was 73.28 micrograms at the same location as the highest total petroleum hydrocarbon mass. Some soil-gas samplers detected toluene mass greater than the method detection level of 0.02 microgram; the highest detection of toluene mass was 0.07 microgram. Some soil-gas samplers were installed in areas of high-contaminant mass to assess for explosives and chemical agents. Explosives or chemical agents were not detected above their respective method detection levels for all soil-gas samplers installed. Inorganic concentrations in five soil samples collected did not exceed regional screening levels established by the U.S. Environmental Protection Agency. Barium concentrations, however, were up to eight times higher than the background concentrations reported in similar Coastal Plain sediments of South Carolina.

    Prostate cancer is the second leading cause of cancer-related deaths in US males, yet much remains to be learned about the role of inflammation in its etiology. We hypothesized that preexisting exposure to chronic inflammatory conditions caused by infectious agents or inflammatory diseases increase the risk of prostate cancer. Using the 2009-2010 National Health and Nutrition Examination Survey, we examined the relationships between demographic variables, inflammation, infection, circulating plasma C-reactive protein (CRP), and the risk of occurrence of prostate cancer in US men over 18 years of age. Using IBM SPSS, we performed bivariate and logistic regression analyses using high CRP values as the dependent variable and five study covariates including prostate cancer status. From 2009 - 2010, an estimated 5,448,373 men reported having prostate cancer of which the majority were Caucasian (70.1%) and were aged 40 years and older (62.7%). Bivariate analyses demonstrated that high CRP was not associated with an increased risk of prostate cancer. Greater odds of having prostate cancer were revealed for men that had inflammation related to disease (OR = 1.029, CI 1.029-1.029) and those who were not taking drugs to control inflammation (OR = 1.330, CI 1.324-1.336). Men who did not have inflammation resulting from non-infectious diseases had greater odds of not having prostate cancer (OR = 1.031, CI 1.030-1.031). Logistic regression analysis yielded that men with the highest CRP values had greater odds of having higher household incomes and lower odds of having received higher education, being aged 40 years or older, being of a race or ethnicity different from other, and of having prostate cancer. Our results show that chronic inflammation of multiple etiologies is a risk factor for prostate cancer and that CRP is not associated with this increased risk. Further research is needed to elucidate the complex interactions between inflammation and prostate cancer.

    Consumption of empty calories, the sum of energy from added sugar and solid fat, exceeds recommendations, but little is known about where US children obtain these empty calories. The objectives of this study were to compare children's empty calorie consumption from retail food stores, schools, and fast food restaurants; to identify food groups that were top contributors of empty calories from each location; and to determine the location providing the majority of calories for these key food groups. This cross-sectional analysis used data from 3,077 US children aged 2-18 years participating in the 2009-2010 National Health and Nutrition Examination Survey. The empty calorie content of children's intake from stores (33%), schools (32%), and fast food restaurants (35%) was not significantly different in 2009-2010. In absolute terms, stores provided the majority of empty calorie intake (436 kcal). The top contributors of added sugar and solid fat from each location were similar: sugar sweetened beverages (SSBs), grain desserts, and high-fat milk from stores; high-fat milk, grain desserts, and pizza from schools; and SSBs, dairy desserts, french fries, and pizza from fast food restaurants. Schools contributed about 20% of children's intake of high-fat milk and pizza. In conclusion, these findings support the need for continued efforts to reduce empty calorie intake among US children aimed not just at fast food restaurants, but also at stores and schools. The importance of reformed school nutrition standards was suggested, as prior to their implementation, schools resembled fast food restaurants in their contributions to empty calorie intake.

  1. Potential Applications of Concentrated Solar Thermal Technologies in the Australian Minerals Processing and Extractive Metallurgical Industry

    The Australian minerals processing and extractive metallurgy industries are responsible for about 20% of Australia's total greenhouse gas (GHG) emissions. This article reviews the potential applications of concentrated solar thermal (CST) energy in the Australian minerals processing industry to reduce this impact. Integrating CST energy into these industries would reduce their reliance upon conventional fossil fuels and reduce GHG emissions. As CST technologies become more widely deployed and cheaper, and as fuel prices rise, CST energy will progressively become more competitive with conventional energy sources. Some of the applications identified in this article are expected to become commercially competitive provided the costs for pollution abatement and GHG mitigation are internalized. The areas of potential for CST integration identified in this study can be classed as either medium/low-temperature or high-temperature applications. The most promising medium/low-grade applications are electricity generation and low grade heating of liquids. Electricity generation with CST energy—also known as concentrated solar power—has the greatest potential to reduce GHG emissions out of all the potential applications identified because of the 24/7 dispatchability when integrated with thermal storage. High-temperature applications identified include the thermal decomposition of alumina and the calcination of limestone to lime in solar kilns, as well as the production of syngas from natural gas and carbonaceous materials for various metallurgical processes including nickel and direct reduced iron production. Hybridization and integration with thermal storage could enable CST to sustain these energy-intensive metallurgical processes continuously. High-temperature applications are the focus of this paper.

    Soil gas and soil were assessed for contaminants at the Patterson Anti-Tank Range at Fort Gordon, Georgia, from October 2009 to September 2010. The assessment included identifying and delineating organic contaminants present in soil-gas samplers from the area estimated to be the Patterson Anti-Tank Range and in the hyporheic zone and floodplain of Brier Creek. This assessment was conducted to provide environmental contamination data to Fort Gordon personnel pursuant to requirements for the Resource Conservation and Recovery Act Part B Hazardous Waste Permit process. Soil-gas samplers in the hyporheic zone and floodplain of Brier Creek contained total petroleum hydrocarbons, benzene, octane, and pentadecane concentrations above method detection levels. All soil-gas samplers within the boundary of the Patterson Anti-Tank Range contained total petroleum hydrocarbons above the method detection level. The highest total petroleum hydrocarbon mass detected was 147.09 micrograms in a soil-gas sampler located near the middle of the site and near the remnants of a manmade earthen mound and trench. The highest toluene mass detected was 1.04 micrograms and was located in the center of the Patterson Anti-Tank Range and coincides with a manmade earthen mound. Some soil-gas samplers installed detected undecane masses greater than the method detection level of 0.04 microgram, with the highest detection of soil-gas undecane mass of 58.64 micrograms collected along the southern boundary of the site. Some soil-gas samplers were installed in areas of high-contaminant mass to assess for explosives and chemical agents. Explosives or chemical agents were not detected above their respective method detection levels for all soil-gas samplers installed.

    In today’s scenario to combat with climate change effects, there are a lot of reasons why we all should use renewable energy sources instead of fossil fuels. Solar energy is one of the best options based on features like good for the environment, independent of electricity prices, underutilized land, grid security, sustainable growth, etc. This concept paper is oriented primarily focused on the use of Solar Energy for the crude oil heating purpose besides other many prospective industrial applications to reduce cost, carbon footprint and moving towards a sustainable and ecologically friendly Oil & Gas Industry. Concentrated Solar Power technology based prototype system is proposed to substitute the presently used system based on natural gas burning method. The hybrid system which utilizes the solar energy in the oil and gas industry would strengthen the overall field working conditions, safety measures and environmental ecology. 40% reduction on natural gas with this hybrid system is estimated. A positive implication for an environment, working conditions and safety precautions is the additive advantage. There could also decrease air venting of CO2, CH4 and N2O by an average of 30-35%.

    Soil gas, soil, and water were assessed for organic and inorganic constituents at the former 19th Street landfill at Fort Gordon, Georgia, from February to September 2010. Passive soil-gas samplers were analyzed to evaluate organic constituents in the hyporheic zone and flood plain of a creek and soil gas within the estimated boundaries of the former landfill. Soil and water samples were analyzed to evaluate inorganic constituents in soil samples, and organic and inorganic constituents in the surface water of a creek adjacent to the landfill, respectively. This assessment was conducted to provide environmental constituent data to Fort Gordon pursuant to requirements of the Resource Conservation and Recovery Act Part B Hazardous Waste Permit process. The passive soil-gas samplers deployed in the water-saturated hyporheic zone and flood plain of the creek adjacent to the former landfill indicated the presence of total petroleum hydrocarbon (TPH) and octane above method detection levels in groundwater beneath the creek bed and flood plain at all 12 soil-gas sampler locations. The TPH concentrations ranged from 51.4 to 81.4 micrograms per liter. Octane concentrations ranged from 1.78 to 2.63 micrograms per liter. These detections do not clearly identify specific source areas in the former landfill; moreover, detections of TPH and octane in a soil-gas sampler installed at a seep on the western bank of the creek indicated the potential for these constituents to be derived from source areas outside the estimated boundaries of the former landfill. A passive soil-gas sampler survey was conducted in the former landfill from June 30 to July 5, 2010, and involved 56 soil-gas samplers that were analyzed for petroleum and halogenated compounds not classified as chemical agents or explosives. The TPH soil-gas mass exceeded 2.0 micrograms in 21 samplers. Most noticeable are the two sites with TPH detections which are located in and near the hyporheic zone and are likely to affect

    The U.S. Geological Survey, in cooperation with the U.S. Department of the Army Environmental and Natural Resources Management Office of the U.S. Army Signal Center and Fort Gordon, Georgia, assessed the hyporheic zone, flood plain, soil gas, soil, and surface-water for contaminants at the Old Incinerator Area at Fort Gordon, from October 2009 to September 2010. The assessment included the detection of organic contaminants in the hyporheic zone, flood plain, soil gas, and surface water. In addition, the organic contaminant assessment included the analysis of explosives and chemical agents in selected areas. Inorganic contaminants were assessed in soil and surface-water samples. The assessment was conducted to provide environmental contamination data to the U.S. Army at Fort Gordon pursuant to requirements of the Resource Conservation and Recovery Act Part B Hazardous Waste Permit process. Total petroleum hydrocarbons were detected above the method detection level in all 13 samplers deployed in the hyporheic zone and flood plain of an unnamed tributary to Spirit Creek. The combined concentrations of benzene, toluene, ethylbenzene, and total xylene were detected at 3 of the 13 samplers. Other organic compounds detected in one sampler included octane and trichloroethylene. In the passive soil-gas survey, 28 of the 60 samplers detected total petroleum hydrocarbons above the method detection level. Additionally, 11 of the 60 samplers detected the combined masses of benzene, toluene, ethylbenzene, and total xylene above the method detection level. Other compounds detected above the method detection level in the passive soil-gas survey included octane, trimethylbenzene, perchlorethylene, and chloroform. Subsequent to the passive soil-gas survey, six areas determined to have relatively high contaminant mass were selected, and soil-gas samplers were deployed, collected, and analyzed for explosives and chemical agents. No explosives or chemical agents were detected above

    The authors discuss material constitution of columbite ore sample and recommend optimized pretreatment modes to obtain ball milling products at the maximum dissociation of ore minerals in aggregates. A concentration technology is proposed, with division of material into two flows –0.315 mm and –0.2 mm in sizes, generated in the milling and screening cycles and subjected to gravity–magnetic and magnetic–gravity treatment, respectively. It is shown that the technology ensures production of both tantalum–niobium and zircon concentrates. It has become possible to additionally recover rare metal components Nb2O5 and ZrO2 from tailings through flotation.

    This report examines the remaining challenges to achieving the competitive concentrating solar power (CSP) costs and large-scale deployment envisioned under the U.S. Department of Energy's SunShot Initiative. Although CSP costs continue to decline toward SunShot targets, CSP acceptance and deployment have been hindered by inexpensive photovoltaics (PV). However, a recent analysis found that thermal energy storage (TES) could increase CSP's value--based on combined operational and capacity benefits--by up to 6 cents/kWh compared to variable-generation PV, under a 40% renewable portfolio standard in California. Thus, the high grid value of CSP-TES must be considered when evaluating renewable energy options. An assessment of net system cost accounts for the difference between the costs of adding new generation and the avoided cost from displacing other resources providing the same level of energy and reliability. The net system costs of several CSP configurations are compared with the net system costs of conventional natural-gas-fired combustion-turbine (CT) and combined-cycle plants. At today's low natural gas prices and carbon emission costs, the economics suggest a peaking configuration for CSP. However, with high natural gas prices and emission costs, each of the CSP configurations compares favorably against the conventional alternatives, and systems with intermediate to high capacity factors become the preferred alternatives. Another analysis compares net system costs for three configurations of CSP versus PV with batteries and PV with CTs. Under current technology costs, the least-expensive option is a combination of PV and CTs. However, under future cost assumptions, the optimal configuration of CSP becomes the most cost-effective option.

    Full Text Available BACKGROUND: This study was carried out to estimate the vaccination coverage, public perception, and preventive behaviors against pandemic influenza A (H1N1 and to understand the motivation and barriers to vaccination between high-risk and non-high-risk groups during the outbreak of pandemic influenza A (H1N1. METHODOLOGY/PRINCIPAL FINDINGS: A cross-sectional nationwide telephone survey of 1,650 community-dwelling Korean adults aged 19 years and older was conducted in the later stage of the 2009-2010 pandemic influenza A (H1N1 outbreak. The questionnaire identified the demographics, vaccination status of participants and all household members, barriers to non-vaccination, perceived threat, and preventive behaviors. In Korea, the overall rate of pandemic influenza vaccination coverage in the surveyed population was 15.5%; vaccination coverage in the high-risk group and non-high-risk group was 47.3% and 8.0%, respectively. In the high-risk group, the most important triggering event for vaccination was receiving a notice from a public health organization. In the non-high-risk group, vaccination was more strongly influenced by previous experience with influenza or mass media campaigns. In both groups, the most common reasons for not receiving vaccination was that their health was sufficient to forgo the vaccination, and lack of time. There was no significant difference in how either group perceived the threat or adopted preventive behavior. The predictive factors for pandemic influenza vaccination were being elderly (age ≥ 65 years, prior seasonal influenza vaccination, and chronic medical disease. CONCLUSIONS/SIGNIFICANCE: With the exception of vaccination coverage, the preventive behaviors of the high-risk group were not different from those of the non-high-risk group during the 2009-2010 pandemic. For future pandemic preparedness planning, it is crucial to reinforce preventive behaviors to avoid illness before vaccination and to increase

    During this period, FDA focused considerable effort on its transparency initiative, which is likely to continue into the coming year, as well as continuing to ramp up its enforcement activities, as we predicted last year. The scope of the agency's ability to pre-empt state laws in product liability litigation involving pharmaceutical products still is developing post-Levine, and we are likely to see new decisions in the coming year. Fraud and abuse enforcement still is a major factor facing the industry, with the added threat of personal exposure to criminal sentences, fines and debarment from participation in federal and state programs under the Responsible Corporate Officer doctrine, or under the authorities exercised by the Department of Health and Human Services Office of the Inspector General. Consequently, it is increasingly important that senior corporate officers ensure active oversight of an effective compliance program which should mitigate these risks. The Federal Trade Commission continues to battle consumer fraud, particularly respecting weight loss programs, and it appears to be fighting a losing battle in its effort to prevent "reverse" payments to generic manufacturers by Innovator Manufacturers to delay the introduction of generics to the market. The Securities and Exchange Commission continues to be actively enforcing the Foreign Corrupt Practices Act. The Supreme Court gave shareholders more leeway in bringing stockholder suits in situations where a company conceals information that, if revealed, could have a negative effect on stock prices.

    The activity of three anthelmintics (fenbendazole-FBZ; oxibendazole-OBZ; and pyrantel pamoate-PRT) was ascertained against the ascarid Parascaris equorum in horse foals on eight farms in Central Kentucky (2009-2010) in field tests. A total of 316 foals were treated, and 168 (53.2%) were passing ascarid eggs on the day of treatment. Evaluation of drug efficacy was determined qualitatively by comparing the number of foals passing ascarid eggs in their feces before and after treatment. The main purpose was to obtain data on current activity of these compounds against ascarids. Additionally, the objective was to compare these findings with those from earlier data on the efficacy of these three compounds on nematodes in foals in this geographical area. Efficacies (average) for the foals ranged for FBZ (10 mg/kg) from 50% to 100% (80%), for OBZ (10 mg/kg) from 75% to 100% (97%), and for PRT at 1× (6.6 mg base/kg) from 0% to 71% (2%) and at 2× (13.2 mg base/kg) 0% to 0% (0%). Although the efficacy varied among the drugs, combined data for all farms indicated a significant reduction of ascarid infections for FBZ (p < 0.0001) and OBZ (p < 0.0001) but not for PRT (p = 0.0953).

  1. 'Rhyme or reason?' Saying no to mass vaccination: subjective re-interpretation in the context of the A(H1N1) influenza pandemic in Sweden 2009-2010.

    During the swine flu pandemic of 2009-2010, all Swedish citizens were recommended to be vaccinated with the influenza vaccine Pandemrix. However, a very serious and unexpected side effect emerged during the summer of 2010: more than 200 children and young adults were diagnosed with narcolepsy after vaccination. Besides the tragic outcome for these children and their families, this adverse side effect suggests future difficulties in obtaining trust in vaccination in cases of emerging pandemics, and thus there is a growing need to find ways to understand the complexities of vaccination decision processes. This article explores written responses to a questionnaire from a Swedish folk life archive as an unconventional source for analysing vaccine decisions. The aim is to investigate how laypersons responded to and re-interpreted the message about the recommended vaccination in their answers. The answers show the confusion and complex circumstances and influences in everyday life that people reflect on when making such important decisions. The issue of confusion is traced back to the initial communications about the vaccination intervention in which both autonomy and solidarity were expected from the population. Common narratives and stories about the media or 'big pharma capitalism' are entangled with private memories, accidental coincidences and serendipitous associations. It is obvious that vaccination interventions that require compliance from large groups of people need to take into account the kind of personal experience narratives that are produced by the complex interplay of the factors described by the informants.

    We investigated the association between monovalent influenza A (H1N1) pdm09 (H1N1pdm) vaccine and pneumonia in elderly people. Study design was a hospital-based, matched case-control study. Cases comprised patients ≥ 65 years old who had been newly diagnosed with pneumonia. For each case, 2 controls were defined as individuals with other diseases (not pneumonia) who were matched by sex, age, entry date, and the visited hospital. Study period was the interval from 1 September 2009 until 30 September 2010. Because a pandemic of influenza A (H1N1) occurred during study period, we analyzed selected subjects who had enrolled during the influenza A (H1N1) pandemic. We calculated the odds ratios (ORs) and 95% confidence intervals (CIs) for pneumonia in H1N1pdm-vaccinated subjects compared with unvaccinated subjects using a conditional logistic regression model to assess the association between H1N1pdm vaccine and pneumonia. The subjects during the period of the influenza A (H1N1) pandemic were 20 cases and 40 controls. Subjects who had received H1N1pdm vaccine showed a significantly decreased OR for pneumonia (OR = 0.10, 95% CI = 0.01-0.98) compared with unvaccinated subjects. In conclusion, H1N1pdm vaccination may have prevented pneumonia among the elderly during the 2009-2010 influenza A (H1N1) pandemic in Japan.

    Unlike traditional fossil fuel plants, the wind and the sun provide power only when the renewable resource is available. To accommodate large scale use of renewable energy sources for efficient power production and utilization, energy storage systems are necessary. Here, we introduce a scalable energy storage system which operates by performing cycles during which energy generated from renewable resource is first used to produce highly concentrated brine and diluate, followed up mixing these two solutions in order to generate power. In this work, we present theoretical results of the attainable energy density as function of salt type and concentration. A linearized Nernst-Planck model is used to describe water, salt and charge transport. We validate our model with experiments over wide range of sodium chloride concentrations (0.025-3 m) and current densities (-49 to +33 A m-2). We find that depending on current density, charge and discharge steps have significantly different thermodynamic efficiency. In addition, we show that at optimal current densities, mechanisms of energy dissipation change with salt concentration. We find the highest thermodynamic efficiency at low concentrate concentrations. When using salt concentrations above 1 m, water and co-ion transport contribute to high energy dissipation due to irreversible mixing.

    This report describes the first and second phases of a three phase project, the object of which is to develop energy efficient separation, concentration, and drying processes for food products, especially juice products, in order to reduce energy requirements and their associated costs for processing, preservation, and transportation. Presently in juice processing, much water is eliminated through evaporation. However, there are significant limits to the current evaporation technology. If, however, the juice could be separated, prior to evaporation, into liquid and solid fractions, and the liquid concentrated further, the containerization and transportation costs could be significantly reduced. Separation methods investigated in this project are: vacuum filtration, centrifugation, and crossflow microfiltration.

    The Laser grooved buried contact silicon solar cell (LGBC) process employed by Narec currently produces LGBC cells designed to operate at concentrations ranging from 1-100 suns and has demonstrated efficiencies at 50X of over 19% and at 100X of over 18.2% using 300 μm CZ silicon[1] wafers. As part of the LAB2LINE[1], APOLLON[2] and ASPIS[3] projects funded under the European Commission Framework Programs (FP6 and FP7) we have made improvements to the LGBC process to improve efficiency or make the cell technology more suitable for industrial CPV receiver manufacturing processes. We describe a process which hybridizes LGBC and more standard screen printing technologies which yields at least a 6% relative improvement at concentration when using more readily available 200 μm thick CZ wafers. We describe a pioneering front dicing technique (FDT). The FDT process is important in small cells where edge recombination effects are detrimental to the performance. We show that by using this new technique we can produce cells that perform better at concentration and improve the positioning of the front contact of the cell. We also describe a busbar technology that uses laser processing and electroless chemical plating to allow not only soldering to the front contact of the cell but also wire bonding. The advances in research and development of LGBC cells leading to improved cell performance may provide significant reductions in levilised cost of energy (LCOE) for low to medium CPV systems.

Novel Biomed 2013;1:23-28.As the articles in recent years well indicate, more than all other factors, social determinants of health are involved in people's health status and quality of life (QOL. Among these social factors, the economic one is introduced as the main factor determining health status. This study was designed to evaluate the impact of poverty on QOL. The health-related QOL of poor people under coverage of a public charity institution (group 1 was compared with the QOL of ordinary people (group2 using the SF-36 questionnaire. The QOL scores in the groups 1 and 2 were analyzed by Mann-Whitney, Kruskal -Wallis tests and logistic regression using the SPSS 16.00 software. A total of 400 individuals were studied. The results showed significant differences between the two groups in the QOL measures of SF-36, except for physical and mental health measures (P<0.001. With regard to the adverse consequence of the Physical Component Scale (PCS, employing logistic regression analysis, statistically significant relationships between the two groups in the demographic characteristics, except age and marital status, were found. For the adverse consequence of Mental Component Scale (MCS, logistic regression showed statistically significant differences between the two groups in the demographic characteristics, except for age. The findings indicate that poverty diminishes the QOL in most aspects; however, considering all aspects of QOL is necessary to promote the individuals' health.

  10. Supply of neuraminidase inhibitors related to reduced influenza A (H1N1) mortality during the 2009-2010 H1N1 pandemic: summary of an ecological study.

    When the influenza A (H1N1) pandemic spread across the globe from April 2009 to August 2010, many WHO Member States used antiviral drugs, specifically neuraminidase inhibitors (NAIs) oseltamivir and zanamivir, to treat influenza patients in critical condition. Antivirals have been found to be effective in reducing severity and duration of influenza illness, and likely reduce morbidity; however, it is unclear whether NAIs used during the pandemic reduced H1N1 mortality. To assess the association between antivirals and influenza mortality, at an ecologic level, country-level data on supply of oseltamivir and zanamivir were compared to laboratory-confirmed H1N1 deaths (per 100 000 people) from July 2009 to August 2010 in 42 WHO Member States. From this analysis, it was found that each 10% increase in kilograms of oseltamivir, per 100 000 people, was associated with a 1·6% reduction in H1N1 mortality over the pandemic period [relative rate (RR) = 0·84 per log increase in oseltamivir supply]. Each 10% increase in kilogram of active zanamivir, per 100 000, was associated with a 0·3% reduction in H1N1 mortality (RR = 0·97 per log increase). While limitations exist in the inference that can be drawn from an ecologic evaluation, this analysis offers evidence of a protective relationship between antiviral drug supply and influenza mortality and supports a role for influenza antiviral use in future pandemics.

To determine the prevalence of dermatological, ear and ophthalmological alterationsclinically presumptive to be caused by fungi and to analyze their occurrence demographically. Materials and methods. We carriedout a retrospective study in a clinic in Bogota for small animals. We reviewed the medical histories of patients who requested medicalappointments due to dermatological, ear and ophtalmological alterations in 2009 and 2010. Results. In the assessed period, the prevalenceof dermatological alterations in dogs was of 7.8%, 4.2% of ear alterations and of 3.3% of ophtalmological alterations. The main etiologicalsuspects through clinical diagnosis were: dermatophytes with an incidence of 86.9% among dermatological alterations, Malasseziawith an 86.5% of incidence in ear alterations, and Candida with 83.3% of incidence in ophtalmological alterations. Statistical analysisof variables showed no association with symptoms or clinically diagnosed etiological agents, but the categorized evaluation showedassociations of races and ages with the etiologies through clinical diagnosis. The diagnosis of fungal etiologies was accomplished in mostcases by clinical findings and less frequently by skin scrapings and ear cytology; in none of the cases a mycological culture was done.The feline population showed no dermatological, ear or ophtalmological alterations compatible with a fungal etiology. Conclusion. In canines, the prevalence of dermatological alterations clinically compatible with dermatophytes was of 86.9%; ear alterations associated with Malassezia were of 86.5%; and ophtalmological alterations Candida-suspected were 83.3%. Final diagnoses were accomplished with the help of clinical findings without following standard diagnostic methodologies such as cultivation.

    This article builds upon previous theoretical work on job loss as a status passage to help explain how people's experiences of involuntary unemployment affected their mental well-being during the 2009-2010 economic recession. It proposes a middle-range theory that interprets employment transitions as status passages and suggests that their health and well-being effects depend on the personal and social meanings that people give to them, which are called properties of the transitions. The analyses, which used a thematic approach, are based on the findings of a qualitative study undertaken in Bradford (North England) consisting of 73 people interviewed in 16 focus groups. The study found that the participants experienced their job losses as divestment passages characterised by three main properties: experiences of reduced agency, disruption of role-based identities, for example, personal identity crises, and experiences of 'spoiled identities', for example, experiences of stigma. The proposed middle-range theory allows us to federate these findings together in a coherent framework which makes a contribution to illuminating not just the intra-personal consequences of unemployment, that is, its impact on subjective well-being and common mental health problems, but also its inter-personal consequences, that is, the hidden and often overlooked social processes that affect unemployed people's social well-being. This article discusses how the study findings and the proposed middle-range theory can help to address the theoretical weaknesses and often contradictory empirical findings from studies that use alternative frameworks, for example, deprivation models and 'incentive theory' of unemployment.

    1987-07-01

    During a 17 month survey of air pollution in the town of Armadale, central Scotland, the concentrations of some metals (iron, manganese, zinc, lead, copper, chrome, nickel, cadmium, and cobalt) were measured in seven types of low technology sampler--four indigenous and three transplanted--at 47 sites. The geographical patterns of the concentrations in the samplers were compared on two types of map. For most metals, sites with high concentrations were present close to the foundry and also in the north of the town. The differences between the patterns of pollution shown by the various types of sampler probably reflected differing mechanisms for collection and different affinities for various sizes and types of metal particle.

    Globally, drinking water resources are diminishing in both quantity and quality. This situation has renewed interest in Condensation Water From Air (CWFA) technology, which utilizes water vapor in the air to produce water for both potable and non-potable purposes. However, there are currently insufficient data available to determine the relationship between air contaminants and the rate at which they are transferred from the air into CWFA untreated product water. This study implemented a novel experimental method utilizing an environmental test chamber to evaluate how air quality and temperature affects CWFA untreated product water quality in order to collect data that will inform the type of water treatment required to protect human health. This study found that temperature and benzene air concentration affected the untreated product water from a CWFA system. Benzene vapor concentrations representing a polluted outdoor environment resulted in benzene product water concentrations between 15% and 23% of the USEPA drinking water limit of 5μg/l. In contrast, product water benzene concentrations representing an indoor industrial environment were between 1.4 and 2.4 times higher than the drinking water limit. Lower condenser coil temperatures were correlated with an increased concentration of benzene in the product water. Environmental health professionals and engineers can integrate the results of this assessment to predict benzene concentrations in the product water and take appropriate health protective measures.

    Thymus capitatus is a Mediterranean plant characterized by its antioxidant polyphenols of which the most known are the carnosic and rosmarinic acids. In this way, this study aims to concentrate these acids by membrane processes. The thyme essential oil composition was established by capillary GC-MS and 27 components were identified representing 98.93%± 1.97% of total oils. The antioxidant test for permeate and retentate of methanolic and aqueous extract were determined using 3 types of membranes. The results showed that the synthetic NF membrane is able to trap and concentrate phenolic compounds in the retentate much better than the NF commercial and UF synthetic membrane. The results of the total phenolic content (TPC) showed a significant value of the polyphenol content present in the aqueous extract with 175.53 mg Gallic Acid Equivalents (GAE)/g of extract. The spectrum of the aqueous extract of Thymus capitatus showed the presence of 3 visible peaks, the 1st one at 217 nm corresponding to the carnosic acid, the 2nd one at 277 nm for essential oils, and the last one at 326 nm attributed to the rosmarinic acid. The commercial membrane NF-DK succeeded to concentrate rosmarinic acid and can be considered as a stage towards the concentration of this product with a high added value.

    Conventional inhaled NO systems deliver NO by synchronized injection or continuous NO flow in the ventilator circuitry. Such methods can lead to variable concentrations during inspiration that may differ from desired dosing. NO concentrations in these systems are generally monitored through electrochemical methods that are too slow to capture this nuance and potential dosing error. A novel technology that reduces NO2 into NO via low-resistance ascorbic-acid cartridges just prior to inhalation has recently been described. The gas volume of these cartridges may enhance gas mixing and reduce dosing inconsistency throughout inhalation. The impact of the ascorbic-acid cartridge technology on NO concentration during inspiration was characterized through rapid chemiluminescence detection during volume control ventilation, pressure control ventilation, synchronized intermittent mandatory ventilation and continuous positive airway pressure using an in vitro lung model configured to simulate the complete uptake of NO. Two ascorbic acid cartridges in series provided uniform and consistent dosing during inspiration during all modes of ventilation. The use of one cartridge showed variable inspiratory concentration of NO at the largest tidal volumes, whereas the use of no ascorbic acid cartridge led to highly inconsistent NO inspiratory waveforms. The use of ascorbic acid cartridges also decreased breath-to-breath variation in SIMV and CPAP ventilation. The ascorbic-acid cartridges, which are designed to convert NO2 (either as substrate or resulting from NO oxidation during injection) into NO, also provide the benefit of minimizing the variation of inhaled NO concentration during inspiration. It is expected that the implementation of this method will lead to more consistent and predictable dosing.

    Methods for the extraction of nucleic acids are straightforward in instances where there is ample nucleic acid mass in the sample and contamination is minimal. However, applications in areas such as metagenomics, life science research, clinical research, and forensics, that are limited by smaller amounts of starting materials or more dilute samples, require sample preparation methods that are more efficient at extracting nucleic acids. Synchronous coefficient of drag alteration (SCODA) is a novel electrophoretic nucleic acid purification technology that has been tested successfully with both highly contaminated and dilute samples and is a promising candidate for new sample preparation challenges. In this article, as an example of SCODA's performance with limited sample material, we outline a genomic DNA (gDNA) extraction protocol from low abundance cultures of Escherichia coli DH10B. This method is equally well suited to high biomass samples.

    For the past several years many nuclear physics methods of quantitative elemental analysis have been designed. Many of these methods have applied in different devices which have become useful and effective instrument in many industrial laboratories. Methods of a matter structure analysis are based on the intensity detection of the X-ray radiation from the nuclei of elements which are excited by external X-ray source. The production of characteristic X-rays involves transitions of the orbital electrons of atoms in the target material between allowed orbits, or energy states, associated with ionization of the inner atomic shells. One of these methods is X-ray fluorescence analysis, which is widespread in metallurgical and processing industries and is used to identify and measure the concentration of the elements in ores and minerals on a conveyor belt. Samples of copper ore with known concentrations of elements, were taken from the Ural deposit. To excite the characteristic X-rays radionuclide sources 109Cd, with half-life 461.4 days were used. After finding the calibration coefficients, control measurements of samples and averaging of overall samples were made. The measurement error did not exceed 3%.

    Gac (Momordica cochinchinensis Spreng.) fruit, a traditional fruit in Vietnam and other countries of eastern Asia, contains an oil rich in carotenoids, especially lycopene and β-carotene. Carotenoids in gac fruit oil were concentrated using cross-flow filtration. In total recycle mode, effect of membrane pore size, temperature, and transmembrane pressure (TMP) on permeate flux and on retention coefficients has been exploited. Resistance of membrane, polarization concentration, and fouling were also analyzed. Optimum conditions for a high permeate flux and a good carotenoids retention are 5 nm, 2 bars, and 40 °C of membrane pore size, TMP, and temperature, respectively. In batch mode, retentate was analyzed through index of acid, phospholipids, total carotenoids content (TCC), total antioxidant activity, total soluble solids, total solid content, color measurement, and viscosity. TCC in retentate is higher 8.6 times than that in feeding oil. Lipophilic antioxidant activities increase 6.8 times, while hydrophilic antioxidant activities reduce 40%. The major part of total resistance is due to polarization (55%) while fouling and intrinsic membrane contribute about 30% and 24%, respectively. © 2014 Institute of Food Technologists®

    Energy storage will help enable CSP compete by adding flexibility value to a high-variable-generation (solar plus wind) power system (see Mehos et al. 2016). Compared with PV, CSP systems are more complex to develop, design, construct, and operate, and they require a much larger minimum effective scale—typically at least 50 MW, compared with PV systems that can be as small as a few kilowatts. In recent years, PV’s greater modularity and lower LCOE have made it more attractive to many solar project developers, and some large projects that were originally planned for CSP have switched to PV. However, the ability of CSP to use thermal energy storage—and thus provide continuous power for long periods when the sun is not shining—could give CSP a vital role in evolving electricity systems. Because CSP with storage can store energy when net demand is low and release that energy when demand is high, it increases the electricity system’s ability to balance supply and demand over multiple time scales. Such flexibility becomes increasingly important as more variable-generation renewable energy is added to the system. For example, one analysis suggests that, under a 40% renewable portfolio standard in California, CSP with storage could provide more than twice as much value to the electricity system as variable-generation PV. For this reason, enhanced thermal energy storage is a critical component of the SunShot Initiative’s 2020 CSP technology-improvement roadmap.

    Full Text Available The characteristics that define cake quality can be improved by the use of adequate ingredients and a correct balance of the formulation. Fat is used for its effect on softness and because it imparts flavor and calories. Enzymes such as maltogenic α-amylase can also have a positive effect on cake texture during storage by decreasing amylopectin re-crystallization and thus delaying starch retrogradation providing longer-lasting crumb softness. The objective of this study was to determine the effect of different concentrations of maltogenic α-amylase and fat on the technological and sensory characteristics of cakes. Therefore, balanced formulations with three different fat concentrations (20, 40, and 60 g/100 g, based on the flour content were used to evaluate the addition of maltogenic α-amylase (0, 500, and 1000 mg/kg. Technological quality determinations were carried out on days 1, 7, 14, and 21 of storage. The best results in terms of cake quality (greater specific volume, higher crumb moisture content, lower crumb firmness, and greater sensory acceptance were obtained with the combination of 20 g/100 g fat and 1000 mg/kg maltogenic α-amylase (based on the flour content, which proved to be an alternative to reduce the fat levels in the elaboration of this type of product.

    Full Text Available The efficient utilization and conversion of inexpensive invasive raw materials into bioethanol following a biorefinery approach is a priority in the research field of renewable fuel. With this purpose, Acacia dealbata wood samples were pretreated with 1-ethyl-3-methylimidazolium acetate under optimized conditions, and the resulting solids were employed as a substrate for enzymatic hydrolysis. Enzymatic assays were performed according to a complete factorial experimental design, in which the effects of two independent variables (liquor to solid ratio and enzyme to substrate ratio on the kinetics and yields of the xylan and cellulose saccharification were assessed. The Response Surface Methodology was employed for optimizing the experimental conditions. High sugar concentrations (around 80 g/L, and favorable polysaccharide conversions (CCG = 79.4% and XnCX = 77.9%. were predicted by the model under the selected operational conditions (6 g liquor/g substrate, 22 FPU/g. The results reported in this work compare well with other studies dealing with either other ionic liquids or classical pretreatments, using the same raw material or other woody substrates.

  10. Concentrated Ground Plane Booster Antenna Technology for Multiband Operation in Handset Devices

    2014-12-01

    Full Text Available The current demand in the handset antenna field requires multiband antennas due to the existence of multiple communication standards and the emergence of new ones. At the same time, antennas with reduced dimensions are strongly required in order to be easily integrated. In this sense, the paper proposes a compact radiating system that uses two non-resonant elements to properly excite the ground plane to solve the abovementioned shortcomings by minimizing the required Printed Circuit Board (PCB area while ensuring a multiband performance. These non-resonant elements are called here ground plane boosters since they excite an efficient mode of the ground plane. The proposed radiating system comprises two ground plane boosters of small dimensions of 5 mm x 5 mm x 5 mm. One is in charge of the low frequency region (0.824-0.960 GHz and the other is in charge of the high frequency region (1.710-2.170 GHz. With the aim of achieving a compact configuration, the two boosters are placed close to each other in a corner of the ground plane of a handset device (concentrated architecture. Several experiments related to the coupling between boosters have been carried out in two different platforms (barphone and smartphone, and the best position and the required matching network are presented. The novel proposal achieves multiband performance at GSM850/900/1800/1900 and UMTS.

    Concentrated runoff increases erosion and efficiently transfers sediment and associated agrichemicals from upland areas to stream channels. Ephemeral gully erosion on cropland in the U.S. may contribute up to 40% of the sediment delivered to the edge of the field. Typically, conservation practices developed for sheet and rill erosion are also expected to treat ephemeral gully erosion, but technology and tools do not exist to account for the separate benefits and effects of practices on various sediment sources. Practices specifically developed to treat ephemeral gully erosion need further testing, when used in conjunction with sheet and rill erosion control practices. Without improved research studies, subjective observations will continue to be used to satisfy quality criteria in lieu of scientifically defensible, quantitative methods to estimate the impact of gully erosion. Some of the more important limiting components are the identification of and relationships for: (1) ephemeral gully width; (2) soil resistance to gully erosion including a definition for non-erosive layers; (3) the effect of root mass and above ground vegetation on erosion resistance; (4) ephemeral gully networks; and (5) the effect of subsurface flow on ephemeral gullies. Currently, these components are represented through widely divergent to non-existent algorithms. Scientists at the U.S. Department of Agriculture, Agricultural Research Service are currently undertaking extensive research studies to understand the processes associated with concentrated flow erosion in fields and streams of watershed systems. A description of this research and the integration into enhanced technology for concentrated flow assessments critical for developing and testing conservation practices specifically designed for gully and channel erosion control will be provided.

    Molten nitrates can be employed as heat storage fluids in solar concentration power plants. However molten nitrates are corrosive and if operating temperatures are raised to increase efficiencies, the corrosion rates will also increase. High temperature corrosion resistant coatings based on Al have demonstrated excellent results in other sectors such as gas turbines. Aluminide slurry coated and uncoated P92 steel specimens were exposed to the so called Solar Salt (industrial grade), a binary eutectic mixture of 60 % NaNO3 - 40 % KNO3, in air for 2000 hours at 550°C and 580°C in order to analyze their behavior as candidates to be used in future solar concentration power plants employing molten nitrates as heat transfer fluids. Coated ferritic steels constitute a lower cost technology than Ni based alloy. Two different coating morphologies resulting from two heat treatment performed at 700 and 1050°C after slurry application were tested. The coated systems exhibited excellent corrosion resistance at both temperatures, whereas uncoated P92 showed significant mass loss from the beginning of the test. The coatings showed very slow reaction with the molten Solar Salt. In contrast, uncoated P92 developed a stratified, unprotected Fe, Cr oxide with low adherence which shows oscillating Cr content as a function of coating depth. NaFeO2 was also found at the oxide surface as well as within the Fe, Cr oxide.

  18. The effect of nanoparticles and humic acid on technology critical element concentrations in aqueous solutions with soil and sand.

    As a consequence of their growing use in electronic and industrial products, increasing amounts of technology critical elements (TCEs) are being released to the environment. Currently little is known about the fate of many of these elements. Initial research on their potential environmental impact identifies TCEs as emerging contaminants. TCE movement in the environment is often governed by water systems. Research on "natural" waters so far demonstrates that TCEs tend to be associated with suspended particulate matter (SPM), which influences TCE aqueous concentrations (here: concentration of TCEs in dissolved form and attached to SPM) and transport. However, the relative potential of different types of SPM to interact with TCEs is unknown. Here we examine the potential of various types of particulate matter, namely different nanoparticles (NPs; Al2O3, SiO2, CeO2, ZnO, montmorillonite, Ag, Au and carbon dots) and humic acid (HA), to impact TCE aqueous concentrations in aqueous solutions with soil and sand, and thus influence TCE transport in soil-water environments. We show that a combination of NPs and HA, and not NPs or HA individually, increases the aqueous concentrations of TCEs in soil solutions, for all tested NPs regardless of their type. TCEs retained on SPM, however, settle with time. In solutions with sand, HA alone is as influential as NPs+HA in keeping TCEs in the aqueous phase. Among NPs, Ag-NPs and Au-NPs demonstrate the highest potential for TCE transport. These results suggest that in natural soil-water environments, once TCEs are retained by soil, their partitioning to the aqueous phase by through-flowing water is unlikely. However, if TCEs are introduced to soil-water environments as part of solutions rich in NPs and HA, it is likely that NP and HA combinations can increase TCE stability in the aqueous phase and prevent their retention on soil and sand, thus facilitating TCE transport.

    Nowadays Research and Development activities on Solar Thermal Power Generating Systems are supported by some countries around the world. Because of their thermal nature each of these plants can be operated only with solar energy or can be hybridized (solar/fossil fuel) and also with thermal storage systems. These types of solar thermal power plants are: Central Receiver, a circular field of tracking mirrors called helisotats reflects the solar energy onto receiver mounted on top of a central tower. Parabolic Trough, use linear parabolic concentrators to reflect sunlight to a receiver along the focal line (metallic pipe). Inside the pipe solar energy is absorbed in a working fluid with temperatures up to 390 Celsius degrees, which is then piped to a central location to power a conventional steam turbine and Parabolic Dish uses a parabolic dish concentrator to focus solar energy to a receiver and a heat engine/generator, located at the focus of the dish, to generate electrical power. In this document, we present the current status of technologies. A description of market opportunities, cost and technological perspectives are also included.

    Grape harvest date is determined according to the technological and phenolic maturities. These parameters were calculated for different red grape (Vitis vinifera L.) varieties (Cabernet Sauvignon, Merlot, Syrah, Cabernet Franc) over four years (2008, 2009, 2010, and 2011) (642 samples). Titratable acidity and sugar content of the grapes were used to determine the technological maturity, whereas Glories (1 and 2) and ITV (Institut Technique de la Vigne et du Vin) methods were used to monitor their phenolic maturity. The ITV method allows the monitoring of phenolic maturity by the quantification of total polyphenol index and anthocyanins, while the Glories method enables the quantitative evolution of extractable anthocyanins and tannins of the grapes. A correlation was shown between the harvest dates obtained by both ITV and Glories (R2 = 0.7 – 0.93). Phenolic maturity of grapes can, therefore, be optimized by the application of both ITV and Glories. Similarly, a correlation was observed between technological and phenolic harvest dates. The effect of climate on the phenolic content of grapes was also studied. The highest temperatures (up to 25 °C) accompanied by the lowest rainfall (null value), induced the maximal concentration of polyphenols in grapes. Thermal and water stresses were also shown to enhance the grapes’ polyphenolic production. PMID:28134785

El método utilizado consistió en el estudio de casos en 21 fallos entre el 2009-2010, con aplicación de variables sociodemográficas, médicolegales/ científico-forenses utilizadas para la descripción de los casos. En los análisis realizados en SPSS, se calcularon medidas de tendencia central, posición y dispersión a los datos cuantitativos, y a los cualitativos se les calcularon proporciones y razones. Se usó el test de chi cuadrado y un valor de p ≤=0,05 fue considerado como significante. Los resultados obtenidos evidenciaron que las mujeres entre 5-14 años fueron las más afectadas, y sus agresores, prevalentes familiares. La mayoría de los casos fueron actos sexuales abusivos, dos de acto sexual agravado en concurso homogéneo y heterogéneo. El informe médico-legal estuvo en todas las sentencias, y le siguió, en orden de frecuencia, el de psicología forense. Los ausentes en su mayor proporción fueron los de biología o genética forense. La investigación realizada permitió concluir que es tarea de los jueces garantizar la integridad de los menores víctimas de abuso sexual; no obstante, para ello cuentan con poco acervo probatorio científico-forense.

    The U.S. Geological Survey, in cooperation with the U.S. Department of the Army Environmental and Natural Resources Management Office of the U.S. Army Signal Center and Fort Gordon, Georgia, assessed the hyporheic zone, flood plain, soil gas, soil, and surface water for contaminants at the McCoys Creek Chemical Training Area (MCTA) at Fort Gordon, from October 2009 to September 2010. The assessment included the detection of organic contaminants in the hyporheic zone, flood plain, soil gas, and surface water. In addition, the organic contaminant assessment included the analysis of organic compounds classified as explosives and chemical agents in selected areas. Inorganic contaminants were assessed in soil and surface-water samples. The assessment was conducted to provide environmental contamination data to the U.S. Army at Fort Gordon pursuant to requirements of the Resource Conservation and Recovery Act Part B Hazardous Waste Permit process. Ten passive samplers were deployed in the hyporheic zone and flood plain, and total petroleum hydrocarbons (TPH) and octane were detected above the method detection level in every sampler. Other organic compounds detected above the method detection level in the hyporheic zone and flood-plain samplers were trichloroethylene, and cis- and trans- 1, 2-dichloroethylene. One trip blank detected TPH below the method detection level but above the nondetection level. The concentrations of TPH in the samplers were many times greater than the concentrations detected in the blank; therefore, all other TPH concentrations detected are considered to represent environmental conditions. Seventy-one soil-gas samplers were deployed in a grid pattern across the MCTA. Three trip blanks and three method blanks were used and not deployed, and TPH was detected above the method detection level in two trip blanks and one method blank. Detection of TPH was observed at all 71 samplers, but because TPH was detected in the trip and method blanks, TPH was

    All forms of diabetes increase the risk of long-term complications. Blood glucose monitoring is of great importance for controlling diabetes procedure, preventing the complications and improving the patient's life quality. At present, the clinical blood glucose concentration measurement is invasive and could be replaced by noninvasive spectroscopy analytical techniques. The mid-infrared spectral region contains strong characteristic and well-defined absorption bands. Therefore, mid-infrared provides an opportunity for monitoring blood glucose invasively with only a few discrete bonds. Although the blood glucose concentration measurement using mid-infrared spectroscopy has a lot of advantages, the disadvantage is also obvious. The absorption in this infrared region is fundamental molecular group vibration. Absorption intensity is very strong, especially for biological molecules. In this paper, it figures out that the osmosis rate of glucose has a certain relationship with the blood glucose concentration. Therefore, blood glucose concentration could be measured indirectly by measuring the glucose exudate in epidermis layer. Human oral glucose tolerance tests were carried out to verify the correlation of glucose exudation in shallow layer of epidermis layer and blood glucose concentration. As it has been explained above, the mid-infrared spectral region contains well-defined absorption bands, the intensity of absorption peak around 1123 cm-1 was selected to measure the glucose and that around 1170 cm-1 was selected as reference. Ratio of absorption peak intensity was recorded for each set of measurement. The effect and importance of the cleaning the finger to be measured before spectrum measuring are discussed and also verified by experiment.

    Objective To analyze incidence of birth defects in Jingning county and relevant influential factors for the development and evaluation of preventive measures. Methods Birth defects monitoring data were obtained from 4 hospitals in 2009 and 2010 in Jingning county following guidelines of Birth defects monitoring program of Jingning county. The data were analyzed including the incidence of birth defects, defect type, occurrence of birth defects of mothers during pregnancy and all the cases were followed up. Results In two years, the total incidence rate of birth defects was 1.064%, in a total of 26 cases of birth defects, 23 were single defect and 3 were multiple defects. Defect types included five multiple fingers, congenital heart disease, cleft lip, cleft palate, encephalocele. Conclusions Birth defects show a trend of increase in this county. This is most likely due to improvement of technology in perinatal prenatal diagnosis and early postnatal diagnosis. Influential factors that may cause birth defects include maternal illness, unsafe medications during pregnancy and maternal genetic factor. These results indicate that it is necessary to enhance pre-pregnancy care, improve the quality of premarital medical examination, pay attention to genetic consulting and prenatal health care, especially in early pregnancy care. It is also necessary to carry out prenatal screening and improve knowledge on birth defects prevention so as to reduce the occurrence of birth defects.%目的 分析浙江省景宁县出生缺陷的发生状况和影响因素,为制定和评价预防措施提供依据.方法 对景宁县内4家医院依据《景宁县出生缺陷监测方案》要求上报的2009年和2010年出生缺陷监测数据进行汇总,分析出生缺陷的发生率、缺陷类型、发生出生缺陷儿母亲孕期情况,并跟踪随访.结果 共监测景宁县两年中2 443例围产儿,出生缺陷26例,总出生缺陷发生率为10.64‰,其中单发缺陷23

    This final technical report documents ENTECH`s Phase 1 contract with Photovoltaic Manufacturing Technology (PVMaT) project. Under this project we prepared a detailed description of our current manufacturing process for making our unique linear Fresnel lens photovoltaic concentrator modules. In addition, we prepared a detailed description of an improved manufacturing process, which will simultaneously increase module production rates, enhance module quality, and substantially reduce module costs. We also identified potential problems in implementing the new manufacturing process, and we proposed solutions to these anticipated problems. Before discussing the key results of our program, however, we present a brief description of our unique photovoltaic technology. The key conclusion of our PVMAT Phase 1 study is that our module technology, without further breakthroughs, can realistically meet the near-term DOE goal of 12 cents/kWh levelized electricity cost, provided that we successfully implement the new manufacturing process at a production volume of at least 10 megawatts per year. The key recommendation from our Phase 1 study is to continue our PVMaT project into Phase 2A, which is directed toward the actual manufacturing technology development required for our new module production process. 15 refs.

    Summary of results in last project period (1. 10. 2009 - 30. 9. 2010) of SNFS Project "From locomotion to cognition" The research that we have been involved in, and will continue to do, starts from the insight that in order to understand and design intelligent behavior, we must adopt an embodied perspective, i.e. we must take the entire agent, including its shape or morphology, the materials out of which it is built, and its interaction with the environment into account, in addition to the neural control. A lot of our research in the past has been on relatively low-level sensory-motor tasks such as locomotion (e.g. walking, running, jumping), navigation, and grasping. While this research is of interest in itself, in the context of artificial intelligence and cognitive science, this leads to the question of what these kinds of tasks have to do with higher levels of cognition, or to put it more provocatively, "What does walking have to do with thinking?" This question is of course reminiscent of the notorious "...

    The Ministry of Agriculture, Forestry and Fisheries of the Kingdom of Cambodia (MAFF) and The Netherlands Development Organisation (SNV-Cambodia) have agreed on cooperating in the set-up and implementation of a National Biogas Programme. The programme officially started after the launching ceremony in March 2006. The objective the National Biodigester Programme (NBP) is 'The dissemination of domestic biodigesters as an indigenous, sustainable energy source through the development of a commercial, market oriented, biodigester sector in selected provinces of Cambodia'. To evaluate the effectiveness of the NBP a Biodigester User Survey has been undertaken with two specific objectives, being: (1) To evaluate the effect of domestic biodigester installations, as perceived by the user, by conducting a representative quantitative random survey of 120 households constructed till 31/08/2010 under the NBP in 8 provinces in Cambodia as well as how the users have experienced the programme activities such as promotion, construction, quality assurance, training and after-sales service; and (2) To evaluate the impact of the program on sustainable development and on a number of GHG emission causing activities, such as fossil and fuel wood consumption and manure management practices. The results of which are presented in this report. Since the beginning of 2006 the National Biodigester Programme (NBP) has supported the construction of over 8,000 biodigesters by July 2010. This Biodigester User Survey (BUS) aimed to evaluate the effect of domestic biodigester installations by conducting research with selected representatives to obtain a sample with a confidence level of 95%. The sample size was 120 with a two-step random selection, the selection was made from households in the NBP database. First, 12 out of 82 districts with were randomly selected, and secondly 120 households were randomly selected from these 12 districts, which cover 7 of the 8 provinces in which NBP supported the construction of biodigesters.

  10. Health care reform 2009-2010: a neurosurgeon's perspective.

    Science.gov (United States)

    Tippett, Troy M

    2010-12-01

    Organized neurosurgery through its Washington Committee developed a number of principles against which all health care reform legislation was measured, and none of the bills were acceptable. The American Association of Neurological Surgeons/Congress of Neurological Surgeons (AANS/CNS) worked through multiple venues to modify or reject the legislation. In the author's view, the American Medical Association (AMA) supported the bills because its board of trustees was too focused on eliminating the sustainable growth rate, or SGR. Physicians failed to shape the health care debate. The leadership of many medical organizations was not prepared for the debate. Many had no experience in this arena and thus were too willing to let lobbyists dictate their position. In the future there are 3 things organized neurosurgery must do: be prepared, never give in, and stick with their principles. Organized neurosurgery must be prepared by developing leaders that have experience in the full spectrum of organized medicine. Neurosurgeons must not count on others, and because the specialty is small all must be involved. Neurosurgeons must never give in. Organized neurosurgery started 2009 with little support for its positions but by the end of the debate had convinced many other organizations, representing almost 500,000 physicians, to take their position. From an organizational point of view, neurosurgeons should now do 3 things: 1) reform or reject the AMA; 2) develop a real surgical coalition; and 3) change the current political environment. Neurosurgeons must also follow their principles. In the author's opinion the most important principles are: health care as a responsibility, medical liability reform, and the right to privately contract. In the United Kingdom and Germany, where health care is considered a right rather than a responsibility, bureaucratic entities determine whether you have the right to health care just as the Independent Payment Advisory Board, established under the new health care reform law in the US, will soon limit by rationing of health care under the guise of cutting costs. If, however, health care is a responsibility not a right, the obligation is shifted from society to the individual. It puts the patient and the doctor in charge. It is a far better mechanism to control costs and preserve quality without rationing. It becomes our obligation to have health care, and it puts us in charge of our destiny. Proven liability reform was not included in the health care legislation despite the fact that up to $200 billion per year is spent on defensive medicine. Another and possibly the most important principle ignored in the legislation is the right for a patient and his/her physician to privately contract under Medicare without penalty.

    The aim of this work was to determine the chemical, technological and in vitro antioxidant properties of co-products from the industrialisation of some tropical exotic fruits, such as mango, pineapple, guava and passion fruit, and to evaluate their potential use as dietary fibre sources for food enrichment. Proximate compositions were determined, as well as the total, insoluble and soluble fibre contents. The water holding, oil holding and swelling capacities were also determined. For the antioxidant activity, three different test systems were used (ABTS, DPPH and FRAP). The dietary fibre content of the co-products varied in a range between 69.1 and 81.5g/100g on a dry matter basis with a good balanced ratio between insoluble dietary fibre and soluble dietary fibre. Phenol recovery was dependent on the fruit type and the solvent system used. Methanol:acetone was a more efficient solvent for extracting phenols than ethanol. There was a good correlation between total phenol content and antioxidant capacity of the fruit extracts. All samples analysed had good antioxidant capacity. The results of this study indicate that exotic fruit fibres obtained as co-products in the process to obtain juice may be considered a good source of natural compounds with significant antioxidant activity.

    It is widely agreed that hydrogen used as energy carrier and/or storage media may significantly contribute in the reduction of emissions, especially if produced by renewable energy sources. The Hybrid Sulfur (HyS) cycle is considered as one of the most promising processes to produce hydrogen through the water-splitting process. The FP7 project SOL2HY2 (Solar to Hydrogen Hybrid Cycles) investigates innovative material and process solutions for the use of solar heat and power in the HyS process. A significant part of the SOL2HY2 project is devoted to the analysis and optimization of the integration of the solar and chemical (hydrogen production) plants. In this context, this work investigates the possibility to integrate different solar technologies, namely photovoltaic, solar central receiver and solar troughs, to optimize their use in the HyS cycle for a green hydrogen production, both in the open and closed process configurations. The analysis carried out accounts for different combinations of geographical location and plant sizing criteria. The use of a sulfur burner, which can serve both as thermal backup and SO2 source for the open cycle, is also considered.

    Concentrating solar power with thermal energy storage (CSP-TES) is a unique source of renewable energy in that the solar thermal energy can be dispatched similarly to conventional thermal generation. However, CSP-TES plants are energy-limited, meaning that their response might be restricted by solar availability. Therefore, the use of this limited solar energy must be optimally scheduled toprovide the greatest value to the system. The timing of CSP-TES dispatch depends on a variety of factors, including electricity demand patterns, the penetration of variable generation sources, and the configuration of the CSP-TES plant itself. We use an established CSP-TES modeling framework in a commercially available production cost model to compare the dispatch and value of two CSP-TEStechnologies (molten salt towers and parabolic troughs) in a Colorado test system. In addition, we consider a range of configuration parameters, such as the solar multiple and thermal energy storage limit, to evaluate how the operational and capacity value varies with plant configuration.

    The smelting-separation process for metallized pellets of vanadium-bearing titanomagnetite concentrates was studied.The influences of smelting temperature,smelting time,and the basicity of the metallized pellet on vana-dium and iron recovery were investigated.The characteristics of titanium slag were analyzed using X-ray diffraction, energy dispersive spectroscopy,and mineralographic microscopic analysis.The results demonstrate that appropriate increases in smelting temperature and smelting time can improve the vanadium and iron recovery from metallized pel-lets and are beneficial for the slag-iron separation.Although increasing the basicity of the metallized pellet can consid-erably improve the vanadium and iron recovery,the TiO2 grade of titanium slag was decreased.Under the optimal conditions,90·17% of vanadium and 92·98% of iron in the metallized pellet were recovered,and the TiO2 grade of titanium slag was 55·01%.It was found that anosovite,augite,spinel,glassiness,and metallic iron were the main mineral phases of the titanium slag.

    Biogas slurry is the residue after the anaerobic fermentation of excrements from breeding industries. It is rich in nitrogen, phosphorus, potassium, and other nutrients. Biogas slurry is already known to be a valuable resource as a liquid fertilizer that increases crop yields and improves soil quality. However, due to the limited farmland areas around the breeding industries and the inconvenience of separating biogas slurry in application and transportation, research on the concentration of biogas slurry has become increasingly important. Forward osmosis (FO) is an isolation technology based on the natural phenomenon of osmosis with the transportation of water across a semi-permeable membrane. The driving force of water transport is the osmotic pressure difference between the two sides of the membrane, which is contrary to the ordinary pressure-driven membrane processes, such as ultrafiltration and reverse osmosis. Related research on the FO technology has grown significantly, but its application to the concentration of biogas slurry has not yet been reported. This paper reported on the application of the FO technology to the concentration of the biogas slurry, so as to improve its practical value, at a seashore pig farm in Shandong Province, using seawater as the draw solution. Considering that the driving force of FO membrane technology is the concentration difference, variations in the FO membrane flux were determined at different draw solution fluxes (30, 40, 50, 60 and 70 L/h), so as to investigate the effect of draw solution flux on the membrane flux. Furthermore, we studied the influence of concentration multiples (2, 2.5, 3, 3.5, 4) on the FO membrane flux. During all the experiments, biogas slurry concentration time, total dissolved salt (TDS), total potassium, total phosphorus, total nitrogen, and COD were also determined in the concentrated biogas slurry and their recovery ratios were calculated. Then the relationship between the TDS in the concentrated

    Full Text Available Groups of fatty acids (FAs in milk fat can have positive and negative impact on consumer health. Profile of FAs could be influenced by dairy cow nutrition, breed, milk yield level et cetera. The question is what relationships the FAs could have to quality of milk products? Relationships between FAs and their groups to selected milk indicators were studied in Czech Fleckvieh and Holstein cows (64 bulk milk samples. There were 8 herds in 2-year investigation during winter and summer season. The relationship of saturated FAs (SAFA; 66.22% was significant only to lactose (L content (0.290; P < 0.05. The relationships of monounsaturated FAs (MUFA; 29.21% to milk indicators (MIs were in­si­gni­fi­cant (P > 0.05. The relationships of polyunsaturated FAs (PUFA, beneficial for consumer health; 4.53% to MIs were narrower: fat (T, 0.321; P < 0.05; lactose (L, 0.458; P < 0.01; milk alcohol stability (AL, 0.447; P < 0.01; titration acidity (SH, 0.342; P < 0.01; cheese curd quality (KV, 0.427; P < 0.01; milk fermentationability (JSH, 0.529; P < 0.001, streptococci count in yoghurt (Strepto, 0.316; P < 0.05; total count of noble bacteria in yoghurt (CPMUK, 0.314; P < 0.05; streptococci/lactobacilly ratio (StreptoLacto, 0.356; P < 0.01. The relationships of conjugated linoleic acid (CLA; markedly beneficial for health; 0.68% to MIs were: T (0.379; P < 0.01; L (–0.542; P < 0.001; AL (0.266; P < 0.05; KV (0.411; P < 0.01; Strepto (0.260; P < 0.05; StreptoLacto (0.270; P < 0.05. The higher CLA levels were connected in this way with: higher fat content; lower lactose content; lower alcohol stability; lower streptococci count in yoghurt; lower streptococci/lactobacilly ratio in yoghurt. The PUFA and CLA representation decreased with L increase. Simultaneously some technological milk properties such as alcohol sta­bi­li­ty and fermentationability were slightly improved.

    2007-07-01

    Beef muscles cooked by the sous vide system were evaluated for the effects of pre-injection tumbling, brine addition and post-injection tumbling on technological parameters, physical properties, visual appearance and tissue microstructure. The muscles were injected at 120% (over original weight) with a brine formulated to give a concentration of 3.5% whey protein concentrate and 0.7% sodium chloride on an injected raw product basis. Pre-injection tumbling did not affect most of the evaluated parameters. Brine addition reduced significantly the cooking and total weight losses. Total weight loss was 7.2% for injected muscles, and significantly higher (28.2%) for non-injected ones. Brine incorporation increased pH and reduced shear force values of cooked muscles. Extended post-injection tumbling (5rpm-10h) improved brine distribution and visual appearance, and also diminished the shear force values of cooked muscles. However, this treatment increased the weight losses of post-injection tumbling and cooking-pasteurization stages.

Most GBS cases occurred from A (H1N1) influenza vaccine with the highest estimated incidence rate. Only 20 of 32 GBS cases (62.50% ) were classified as "vaccine reaction", and only 5 of 20 GBS cases (25% ) occurred within 1-6 weeks after vaccination, that have the strongest time association with the vaccination. Conclusions GBS after vaccination was very rare, and the estimated incidence rate was lower than the incidence rate of GBS by all causes. The surveillance did not indicate that the vaccination could increase the risk of GBS. We should continue to strengthen the monitoring, investigation, diagnosis and treatment of GBS as AEFI, and to guide the public to better understand the risk of GBS after vaccination, in order to reduce the influence of this concern to the immunization program. We should also strengthen the study of GBS background incidence for the further evaluation of the risk of GBS after vaccination.%目的 分析全国(未包括香港、澳门特别行政区和台湾地区,下同)疑似预防接种异常反应(Adverse Events Following Immunization,AEFI)信息管理系统中,接种疫苗后格林-巴利综合征(Guillain-Barre Syndrome,GBS)的发生特征,评价接种疫苗后GBS的发生风险.方法 通过收集全国2009~2010年AEFI

    Full Text Available Saponins, molecules classified as triterpenic or steroidal glycosides, are metabolites distributed in all the plant kingdom that can be used for the production of foods, cosmetics, and pharmaceuticals, as well as in soil bioremediation. Saponins are normally extracted from natural resources with water, ethanol and/or methanol, and then concentrated by liquid-liquid partitioning with n-butanol. An alternative concentration method is with a foam column, by which the saponins can be concentrated via preferential adsorption at a gas-liquid interface. Therefore, the objective of this work was the use of a foam column for the concentration of saponins from juá and sisal, evaluating parameters such as: initial working volume in the column, saponin concentration in the extracts from juá and sisal, air flow rate, pH, Raschig rings loading and operation time. When a gradient air flow rate and 25 g of Raschig rings were used, 82.6% of the jua saponins loaded onto the system were recovered in a 3.46-fold concentrated solution after 9 h of operation. Regarding sisal saponins, a concentration factor of 1.98 was observed with 90.5% of saponin recovery during 4.5 h of operation.

    An innovative tomographic method using tunable diode laser absorption spectroscopy (TDLAS) and algebraic reconstruction technique (ART) is presented in this paper for detecting two-dimensional distribution of H2O concentration and temperature in a premixed flame. The collimated laser beam emitted from a low cost diode laser module was delicately split into 24 sub-beams passing through the flame from different angles and the acquired laser absorption signals were used to retrieve flame temperature and H2O concentration simultaneously. The efficiency of the proposed reconstruction system and the effect of measurement noise were numerically evaluated. The temperature and H2O concentration in flat methane/air premixed flames under three different equivalence ratios were experimentally measured and reconstruction results were compared with model calculations. Numerical assessments indicate that the TDLAS tomographic system is capable for temperature and H2O concentration profiles detecting even the noise strength reaches 3% of absorption signal. Experimental results under different combustion conditions are well demonstrated along the vertical direction and the distribution profiles are in good agreement with model calculation. The proposed method exhibits great potential for 2-D or 3-D combustion diagnostics including non-uniform flames.

    Full Text Available Introduction & Objective: Polycystic ovary syndrome (PCOS is the most common endocrine disorder in women of reproductive age. According to the Rotterdam criteria, this syndrome is identified by presence of two of three criteria: (1 polycystic ovaries (2 oligo/anovulation and/or (3 clinical or biochemical evidence of hyperandrogenism. Low mature oocyte and embryo have been reported in polycystic ovary syndrome patients undergoing assisted repro-duction. An inverse correlation between follicular fluid homocysteine (Hcy concentration and oocyte and embryo maturity has also been found. This study has been implemented to do more evaluation on the relationship between homocysteine levels in follicular fluid and oo-cyte and embryo quality. Materials & Methods: 30 PCOS patients as case group and 30 women with male factor infertil-ity as control group were included in the study. The follicular fluid in the cases was collected during ovary punition and Hcy level was measured by ELISA method. The oocytes and em-bryos were classified into several groups. The Hcy levels of follicular fluid of two groups were compared and its relation with oocyte and embryo quality was assessed. Results: Although the homocysteine concentration in follicular fluid of the case group was higher than the control group, the differences were not statistically significant. Moreover , no significant correlation was found between oocyte and embryo quality and homocysteine concentration of follicular fluid of the two groups. Conclusion: In our study, no significant correlation was found between oocyte and embryo quality and homocysteine concentration of follicular fluid of PCOS patients but further stud-ies with larger sample sizes are recommended.(Sci J Hamadan Univ Med Sci 2013; 19 (4:11-19

    Within the Munich low emission zone (LEZ), samples of PM(2.5) were collected before (2006/2007) and after (2009/2010) the implementation of the LEZ. The samples were analyzed for carbon fraction (EC/OC) and particulate organic compounds (POC). Significant lower concentrations were noticed for elemental carbon (EC) and some of the POC like vanillic acid, acetosyringone, syringylacetone and syringic acid after the implementation of the LEZ. Higher concentrations of levoglucosan, retene and O-PAH were detected in the second sampling period. Positive matrix factorization (PMF) was used to identify the main sources of POC. Emissions from traffic, solid fuels combustion, cooking and mixed source were separated. The contribution of traffic source factor was decreased about 60% after the implementation of the LEZ. Thus the average concentration of EC from traffic factor decreased from 1.1 to 0.5 μg/m(3) after the implementation of the LEZ.

    An open path Fourier transform IR spectrometer and an ultra- violet differential optical absorption spectrometer were used during the 1996 Atlanta Olympics games to monitor for ambient ozone and its precursors near the Olympic Village. Both systems were operated continuously before, during, and after the increase in Atlanta's population associated with the Summer games. The study utilized the massive changes in population patterns to observe and measure changes in local air quality due to an increased local population. A second goal of the program was to evaluate both open path instruments in continuous field use over a period of several weeks. The evaluation included the following criteria: instrumentation operability, system precision and accuracy, detection capability, and over-all ease of use. Both open path systems selected and measured ambient levels of ozone. A limited number of ozone precursors were detected. The study was sponsored by the Georgia Institute of Technology's Air Quality Laboratory, the US Department of Energy, and the US Environmental Protection Agency.

    近年来,反渗透(RO)在污水厂二级出水深度处理中的应用越来越多.然而,RO浓水的含盐量较高、有机物难于降解,采用常规方法处理时出水水质难于达到排放标准.采用机械蒸汽再压缩技术(MVR)对某污水厂的反渗透浓水进行了6倍浓缩的中试,其出水COD≤50 mg/L、NH-N≤10 mg/L,可以达到(GB/T 18920-2002)的要求;COD、TDS、Mg和色度等指标的浓缩倍数与体系的浓缩倍数基本一致,而浓缩水中的TP、SiO、TN、NH-N浓度却低于原水的,这主要是由于磷酸盐、硅酸盐的沉淀和氨气逸出所致.另外,钙盐等的沉淀作用还造成浓缩水中SS浓度的增加.由此可见,利用MVR处理反渗透浓水在技术上是可行的,但是需要增加沉淀物的预处理和排出气体的收集处理装置.%Recently, the application of reverse osmosis (RO) in advanced treatment of effluent form WWTP becomes very popular. However, due to high salinity and refractory organic compounds in concentrated water of RO, the effluent treated by traditional processes can not meet the discharge standard. A pilot experiment at a concentration factor of 6 was conducted to treat concentrated water from reverse osmosis (RO) process in a sewage treatment plant using mechanical vapor recompression (MVR)technology. COD and NH3 -N in the effluent from MVR process are equal to or less than 50 mg/L and 10 mg/L, meeting the Reuse of Urban Recycling Water-Water Quality Standard for Urban Miscellaneous Water Consumption (GB/T 18920 -2002). The concentration factors of COD, TDS, Mg2+ and color in concentrated water of MVR are similar to those in concentrated water of RO. However, the concentration factors of TP, SiO2, TN and NH3 - N are lower than those in concentrated water of RO due to escape of ammonia and precipitation of phosphate and silicate. In addition, precipitation of calcium salt causes increase of SS in concentrated water of MVR. The experiment shows that MVR technology is

    在红土镍矿湿法浸出过程中,采用氨法沉镁提取镁盐产品后产生的大量工业废水,如直接排放会影响生态环境,一般都会回用做为镍冶炼工业用水.试验表明含铵浓度不超过0.5 g/L时,对沉镍时Ni、Mn沉淀率和耗碱量无影响,反而可以提高含镁废水中的镁含量,有利于含镁废水的氨法沉镁生产工艺.同时解决了镍冶炼过程中含镁母液氨法沉镁后的废水排放问题,达到了生产用水的循环综合利用,有效的节约了水资源,降低了生产成本.%Much quantity of waste water is discharged when magnesium product is produced by ammonia method during nickel is extracted by wet method from laterite nickel ore. The environment will be polluted if the waste water is discharged directly. Waste water is often recycled to be industrial water for nickel smelting. It is showed by experiment that there has no effect on depositing rate of Ni, Mn and the quantity of consumed alkali if the concentration of ammonium is less than 0. 5 g/L. In such a case, the magnesium contented in the waste water is improved and favorable for magnesium production by ammonia depositing method. It can solve the problem of waste water discharging during nickel smelting process because the waste water is recycled to be industrial water after magnesium is deposited by ammonia method. The water resource is saved and the production cost is decreased effectively.

    This paper reviewed the methods of methane (CH4) separation and purification from coal-bed methane (CBM),including low-temperature distillation,adsorption,membrane separation and gas hydrate separation. By the analysis of the advantages and the disadvantages of these methods,the separation efficiencies under different technical conditions were compared and discussed. Key issues needed to be solved for each method were summarized. For the low-temperature distillation method,de-oxidation is necessarily conducted for the oxygen-containing CBM. The selection of the adsorbent is the key for the adsorption method because the adsorbent determines the economy benefit directly. As for the membrane separation,the separation is affected by the selection of the membrane materials and membrane-making technology. For the hydrated-based CH4 separation,a good additive is crucial to promote the hydrate formation and enhance the CH4 separation efficiency. Finally,the separation of multi-methods or the separation by multi-stage processes is proposed for the future development of CBM separation.%  综述了应用于低浓度煤层气分离的主要方法,包括低温精馏法、吸附分离法、膜分离法和水合物法,探讨了各种方法在不同工艺条件下的分离效果,分析了它们的优缺点。文中总结了每种方法需要解决与突破的关键性问题:低温精馏法获得的甲烷浓度高,但在处理含氧煤层气时首先要脱氧;吸附分离的关键技术在于吸附剂的选择,吸附剂决定了该方法的经济效益与难易程度;对于膜法分离,影响煤层气分离效果的主要因素在于膜材料的选择及制膜工艺;对于水合物法,寻找制备具有较高分离效率的添加剂是关键。最后指出,多种方法结合、多级分离的分离方法是未来研究发展方向。

    The Hydraulic Laboratory of the Center for Hydro graphic Studies (CEDEX) is carrying out a study about the behaviour of some salmonid and cyprinid fish species in a vertical slot fishways built in the Laboratory, in order to know the relationship between hydraulic and biological parameters and to obtain valid design criteria. Its the first time in our country that fish are been monitored in a fishways using a RFD system, underwater and cenital cameras. First at all, the hydraulic of this typology has been characterised. An experiment protocol has been established to optimize the results. Regarding fish movements in the fishways, on the one hand we have found that fish always rest ascending the pass and, on the other, an influence of the flow on the percentage of fish that ascend the whole pass. Moreover, a tool analyze the efficiency of a fish way model according to biological criteria has been contrasted but it needs to be calibrated with biological variables obtained from native fish species. concerning fish fatigue and effort, studies about physiological parameters in plasma (hematocrit, glucose, cortisol and lactate) have implemented and the results point out the need to increase the studies with physiological parameters in muscle.

    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

And the increasing of atmospheric CO2 concentration is thought to be the main factor of global warming. There could be a similar linkage of CO2 concentration and greenhouse climate between modern and ancient analogues, for which the estimate of paleoatmospheric CO2 concentration is a first task to reconstruct ancient climate. Then, this paper aims to summarize the main methods and technologies of paleoatmospheric CO2 concentration estimate at the arts of states by analyses and synthetization of recent published references. So far, there are three main methods to reconstruct ancient atmospheric CO2 concentration. They are GEOCARB model, stomatal parameters of fossil plant, and isotopes proxy indicators. The GEOCARB model is an extremely carbon-model relevant, and has been established by Berner (1990s . -2000s), showing a long tendency for changes of ancient atmospheric CO2 concentration. The method of stomatal parameter of fossil plant is used to estimate the CO2 concentration by stomatal ratio, which is often

    The production of oil is associated with waters which exist naturally at the reservoirs or were injected into wells. These waters, named produced waters, contain beside free oil, emulsioned or micro-emulsioned oil which can not be discharged directly at the environment. The conventional decanters are not efficient to separate this kind of oil dispersed as fine droplets. In this case, a promising alternative to solve the problem of oil/water separation is accomplished by means of the phase inversion method. This method is the basis of working of a new model of mixer-settler which has a vertical disposition and occupies a small surface area. The last characteristic becomes especially important when exist a limitation of place, for example, over the maritime platforms to explore oil. The device of laboratory of the equipment named MDIF (mixer-settler based on phase inversion) has been efficient for treat waters containing up to 2 000 mg/L of emulsioned oil. This equipment on a semi-industrial scale was installed in the entrance of oil/water separator (OWS) from effluent treatment plant from Guamare, Rio Grande do Norte (ETP/GMR) and treats produced waters contaminated with oil at low concentrations (ranging from 30 to 150 mg/L) and throughputs of 320 m3/d (47,4 m3 m-2 h-1). Good results were obtained on oil/water separation which leads to the necessary specification to discharge waters. Besides, the non dependence of the efficiency of separation in the face of the salinity of the medium becomes the equipment a new technology to treat wastewaters containing oil at low concentrations. In this condition conventional equipment do not present a good efficiency of separation, till dispersed droplets are very small (less than 100 {mu}m) requiring a long time of sedimentation. (author)

It was to assess on a laboratory scale the quality of coal flotation concentrates from column flotation of fine coal (-500{mu}m) as an alternative to the traditional conventional agitated cell that this work was carried out. The column developed specifically for this purpose allowed the establishment of an approach to the examination of the flotation response of samples of UK coals (originating from Bolsover, Derbyshies; Rawdon, Leicestershire; and Bilsthorpe, Nottinghamshire). The work indicates the importance of the origin of the feed slurry, since each type of coal exhibits a different flotation response. The observations from the results described in this paper enable an assessment to be made of the merits of column flotation in fine coal treatment. 11 refs., 4 figs., 5 tabs.

    Full Text Available Le ricerche avviate nel 2005 nella laguna di Santa Giusta (OR stanno rivelando la presenza di contesti archeologici di età fenicio-punica di eccezionale rilevanza. In uno di questi, localizzato a circa 800 m dall’attuale linea di riva, è stato condotto, a partire dal 2006, uno scavo subacqueo, ancora in corso. Sono stati recuperati numerosi materiali ceramici, in larga parte rappresentati da anfore commerciali, ma anche da ceramica domestica e, più raramente, di carattere funerario e cultuale (VI-III/II sec. a.C.. In vari casi le anfore contenevano resti ossei animali, più spesso di ovicaprini, con evidenti tracce di macellazione; le condizioni anossiche garantite dal substrato limoso hanno favorito la conservazione di materiali organici, tra i quali pigne, semi di diverse specie e legni, prevalentemente lavorati, alcuni ancora in connessione. Research undertaken in 2005 in the lagoon of Santa Giusta (OR is revealing the presence of archaeological contexts of Phoenician-Punic date of exceptional importance. In one of these, located about 800 m from the current shoreline, an underwa­ter excavation was conducted since 2006; it is still in progress. Much pottery has been recovered, mostly represented by transport amphoras, but also by domestic pottery and, more rarely, ceramics associated with funerary and cultic use (6th-2nd century BC. In several cases the amphoras contained animal remains, most often of ovicaprines, with clear traces of slaughter; the anaerobic condi­tions guaranteed by the silty substrate have favoured the preservation of organic materials, including pine cones, seeds of different species and wood, mostly worked and some still joined together.

  13. Medical isotope shortage 2009-2010 and future options NRU, SLOWPOKE and MAPLE

    Energy Technology Data Exchange (ETDEWEB)

    Hilborn, J. [Deep River, Ontario (Canada)

    2013-07-01

    The 15 month shutdown of NRU and the unexpected termination of the AECL/Nordion MAPLE project caused a world-wide shortage of medical isotopes. After the recent repair of NRU, AECL is confident that it could continue operating safely and reliably as a multi-purpose reactor until 2021 or longer. There is convincing evidence that the restoration of the MAPLE reactors is technically feasible, but it is highly improbable that a 10 MW MAPLE production reactor can ever be cost-effective. However, conversion of the present 10 MW reactors to 3 MW, without major changes to the structural hardware, warrants serious consideration. Finally, even the 20 kW SLOWPOKE reactor could produce useful quantities of Mo-99. If the present fuel rods were replaced with a small tank containing a solution of low-enriched uranyl sulphate in water, three of these liquid core reactors could supply all of Canada. (author)

    An update of our 2009 study, "The Future of Nuclear Energy, Facts and Fiction" using the 2009 and the available 2010 data, including a critical look at the just published 2009 edition of the Red Book, is presented. Since January 2009, eight reactors with a capacity of 4.9 GWe have been connected to the electric grid and four older reactors, with a combined capacity of 2.64 GWe have been terminated. Furthermore, 27 reactor constructions, dominated by China (18) and Russia (4), have been initiated. The nuclear fission produced electric energy in 2009 followed the slow decline, observed since 2007, with a total production of 2560 TWhe, 41 TWhe (1.6%) less than in 2008 and roughly 100 TWhe less than in the record year 2006. The preliminary data from the first 10 months of 2010 in the OECD countries indicate that nuclear power production in North-America remained at the 2009 levels, while one observes a recovery in Europe with an increase of 2.5% and a strong rise of 5% in the OECD Asia-Pacific area compared to th...

    International electives can provide experiences for medical students to learn about health systems and foster critical self-reflection. So far, little is known about the status of Japanese students' engagement in international electives. We sought to provide information about the internationalization of Japanese medical education by clarifying the current situations of international electives. We undertook a cross-sectional national 17-item questionnaire survey of program officers in all medical schools in Japan in February 2010. Sixty-five (81.3%) of 80 Japanese medical schools responded to the questionnaire. 462 Japanese medical students (3% of all students in their clinical years) travelled to North America (45.5%), Asia (25.0%), or Western Europe (24.4%) to study abroad. The number of students who participated in international electives was significantly increased when academic credit was available (median 6 vs. 1, p students, p students were evaluated by means of written assignment on return. About 3% of Japanese medical students participate in international clinical exchanges. Academic credit and institutional affiliations appear to promote greater utilization of international exchange opportunities.

    While CDC reports on the health and economic burden of smoking in the United States, state-specific data are not readily available. We estimated the health and economic consequences of cigarette smoking in Alabama to provide the state legislature with the state-specific data that reveal the direct impact of smoking on their constituents. We estimated that in 2009, almost 7,900 adult deaths (18% of all adult deaths) and approximately 121,000 years of potential life lost among Alabama adults aged 35 years and older were attributable to cigarette smoking. Productivity losses due to premature death and smoking-attributable illness were estimated at $2.84 billion and $941 million, respectively. Our findings support a strong need for tobacco control and prevention programs to decrease the health and economic burden of smoking in Alabama. These results are being used by the State Health Officer to illustrate the real costs of smoking in Alabama and to advocate for improved tobacco control policies.

    Describe how antihypertensive drugs are prescribed in France in 2009 and 2010 and assess the effect of the presence of cardiovascular disease on the characteristics of the treatment. The French League Against Hypertension Surveys (FLAHS) are conducted among a representative sample of individuals aged 35 years and older living in France. For the 2009 and 2010 surveys, a sample of 2292 subjects who declared to take one or more antihypertensive drug has been studied. In addition to the details of antihypertensive medications taken the day of the survey, the personal history for cardiovascular diseases was compiled. Of the 2292 prescriptions with at least one antihypertensive prescription frequencies are: ARB (43%), diuretics (43%), beta-blockers (34%), CCB (26%), ACEI (26%), spironolactone (8%), central and alpha (7%), DRI (1%). The prescription is performed as monotherapy (42%), bitherapy (37%), triple therapy (16%) and quadruple or more (5%). When triple therapy is prescribed, there is an association ACEI or ARB or DRI+Diu+BB in 46%, and an association ACEI or ARB or DRI+Diu+AC in 30%. Cardiovascular disease is present or past reported by 24% of hypertensive patients: coronary artery disease (13%), heart failure (6%), arrhythmias (5%), stroke (4%), PAD (4%). The use of BB is more common in hypertensive patients who have coronary artery disease, heart failure and arrhythmia. ACE inhibitors are more common in hypertensive patients with coronary artery disease, heart failure or stroke. CCB are more frequent in cases of coronary artery disease or PAD. The ARB are less frequent in patients with coronary artery disease. The ARB, diuretics and beta-blockers are the most prescribed antihypertensives in France in 2009 to 2010. Cardiovascular diseases declared in 24% of hypertensives led to a preferential prescription of an ACE inhibitor or BB. Copyright © 2012 Elsevier Masson SAS. All rights reserved.

  18. Exhumation and reburials of some anticommunist partisans in county of Cluj, Romania, 2009-2010

    Full Text Available After the Second World War, Romania entered under the USSR political and military sphere of influence, which led to the installation of the communist government. In years that followed many Romanian citizens who didn’t agree with the new regime or its ideology were subjected to terror and repression. Any person suspected of being an enemy of the people would end up in political jails or put to death through collective executions. But there were also people who stood up against the regime. Groups of partisans emerged, groups that endured in forests and mountains for many years, standing up to the Securitatea, the repressive instrument of the state. After the fall of the communist regime, the former “enemies of the people”, victims of repression, benefited from reconsideration and rehabilitation that transformed them into anticommunist heroes. A series of commemorative actions that initiated a new post-communist tradition constitute part of a process called the politics of memory. The processes of unearthing and identification of the victims’ served to map out the magnitude of the crimes, and inventory evidence against the perpetrators. The factual data gathered will be used as incriminating evidence which will help with convicting the executioners. At the same time, the commemorative actions of a large number of victims may, through the representative voices of the survivors’ descendants, symbolically reopen the wounds, cultivate trauma, demonize the Other, identify the Scapegoat. My research aims to show how these theories and mechanisms remain valid and apply to the case of people who were victims of communist repression through isolated and almost anonymous executions. The murder was committed in silence and the murdered is condemned to being forgotten. The exhumation and reburial also remain events with local reverberations.

    Full Text Available Abstract Previously, we explored the epidemic pattern and molecular characterization of noroviruses (NoVs isolated in Chungnam, Korea in 2008, and the present study extended these observations to 2009 and 2010. In Korea, NoVs showed the seasonal prevalence from late fall to spring, and widely detected in preschool children and peoples over 60 years of age. Epidemiological pattern of NoV was similar in 2008 and in 2010, but pattern in 2009 was affected by pandemic influenza A/H1N1 2009 virus. NoV-positive samples were subjected to sequence determination of the capsid gene region, which resolved the isolated NoVs into five GI (2, 6, 7, 9 and 10 and eleven GII genotypes (1, 2, 3, 4, 6, 7, 8, 12, 13, 16 and 17. The most prevalent genotype was GII.4 and occupied 130 out of 211 NoV isolates (61.6%. Comparison of NoV GII.4 of prevalent genotype in these periods with reference strains of the same genotype was conducted to genetic analysis by a phylogenetic tree. The NoV GII.4 strains were segregated into seven distinct genetic groups, which are supported by high bootstrap values and previously reported clusters. All Korean NoV GII.4 strains belonged to either VI cluster or VII cluster. The divergence of nucleotide sequences within VI and VII intra-clusters was > 3.9% and > 3.5%, respectively. The "Chungnam(06-117/2010" strain which was isolated in June 2010 was a variant that did not belong to cluster VI or VII and showed 5.8-8.2%, 6.2-8.1% nucleotide divergence with cluster VI and VII, respectively.

    2011-07-01

    The Rossendorf Beamline (ROBL) - located at BM20 of the European Synchrotron Radiation Facility (ESRF) in Grenoble, France - is in operation since 1998. This 7th report covers the period from January 2009 to December 2010. In these two years, 67 peer- reviewed papers have been published based on experiments done at the beamline, more than in any biannual period before. Six highlight reports have been selected for this report to demonstrate the scientific strength and diversity of the experiments performed on the two end-stations of the beamline, dedicated to Radiochemistry (RCH) and Materials Research (MRH). The beamtime was more heavily overbooked than ever before, with an acceptance rate of only 25% experiments. We would like to thank our external proposal review members, Prof. Andre Maes (KU Leuven, Belgium), Prof. Laurent Charlet (UJF Grenoble, France), Dr. Andreas Leinweber (MPI Metallforschung, Stuttgart, Germany), Prof. David Rafaja (TU Bergakademie Freiberg, Germany), Prof. Dirk Meyer (TU Dresden, Germany), who evaluated the inhouse proposals in a thorough manner, thereby ensuring that beamtime was distributed according to scientific merit. The period was not only characterized by very successful science, but also by intense work on the optics upgrade. In spring 2009, a workshop was held at ROBL, assembling beamline experts from German, Spanish and Swiss synchrotrons, to evaluate the best setup for the new optics. These suggestions was used to prepare the call for tender published in July 2009. From the tender acceptance in November 2009 on, a series of design review meetings and factory acceptance tests followed. Already in July 2010, the first piece of equipment was delivered, the new double-crystal, double-multilayer monochromator. The disassembly of the old optics components started end of July, 2011, followed by the installation of the new components. As of December 2011, the new optics have seen the first test beam and thorough hot commissioning will be continued until May 2012, since the ESRF shuts down for a major upgrade from December 2011 to April 2012. We expect that we will be ready for user operation from June 2012 on, with a better beamline than ever. The beamline staff would like to thank all partners, research groups and organizations who supported the beamline during the last 24 months. Special thanks to the FZD management, the CRG office of the ESRF with Axel Kaprolat as liaison officer and Eric Dettona as lead technician, and to the ESRF safety group members, Paul Berkvens, Patrick Colomp and Yann Pira.

  6. Solar concentrators for space processing applications

    Mcdermit, J. H.; Ruff, R. C.

    1975-01-01

    A study on the technological feasibility of using solar concentrators for crystal growth and zone refining in space has been performed. Previous studies related to the many aspects of the problem are reviewed. It was concluded from this effort that the technology for fabricating, orbiting, and deploying large solar concentrators has been developed. It was also concluded that the technological feasibility of space processing materials in the focal region of a solar concentrator depends primarily on two factors: (1) the ability of a solar concentrator to provide sufficient thermal energy for the process and (2) the ability of a solar concentrator to provide a thermal environment that is conducive to the processes of interest. The study indicates that solar concentrators of reasonable dimensions can satisfactorily provide both of these factors. This study also indicates that solar concentrators are attractive for space processing from the viewpoint of system specific power and system flexibility.

  7. Low concentrator PV optics optimization

    2008-08-01

    Purpose: Cost reduction is a major focus of the solar industry. Thin film technologies and concentration systems are viable ways to reducing cost, with unique strengths and weakness for both. Most of the concentrating PV work focuses on high concentration systems for reducing energy cost. Meanwhile, many believe that low concentrators provide significant cost reduction potential while addressing the mainstream PV market with a product that acts as a flat panel replacement. This paper analyzes the relative benefit of asymmetric vs. symmetric optics for low-concentrators in light of specific PV applications. Approach: Symmetric and asymmetric concentrating PV module performance is evaluated using computer simulation to determine potential value across various geographic locations and applications. The selected optic design is modeled against standard cSi flat panels and thin film to determine application fit, system level energy density and economic value. Results: While symmetric designs may seem ideal, asymmetric designs have an advantage in energy density. Both designs are assessed for aperture, optimum concentration ratio, and ideal system array configuration. Analysis of performance across climate specific effects (diffuse, direct and circumsolar) and location specific effects (sunpath) are also presented. The energy density and energy production of low concentrators provide a compelling value proposition. More significantly, the choice of optics for a low concentrating design can affect real world performance. With the goal of maximizing energy density and return on investment, this paper presents the advantages of asymmetric optic concentration and illustrates the value of this design within specific PV applications.

    1982-04-01

    The design and development of a high concentration photovoltaic concentrator module is discussed. The design concept described herein incorporates a curved groove domed Fresnel lens, a high concentration etched multiple vertical junction (EMVJ) solar cell and a passively cooled direct-bonded copper cell mount all packaged in a plastic module. Two seven inch diameter 1200x domed Fresnel lenses were fabricated using single point diamond turning technology. Testing at both GE and Sandia confirmed optical transmission efficiencies of over 83%. Samples of the latest available EMVJ cells were mounted and installed, with a domed Fresnel lens, into a prototype module. Subsequent testing demonstrated net lens-cell efficiencies of 10 to 13%. As a result of this program, salient conclusions have been formulated as to this technology.

However, because of many factors in practice like the low tracking accuracy of tracker, structure vibration by winds and atmospheric scattering, the direct normal irradiation to the Fresnel lens can not be guaranteed. To solve this problem, a removable secondary mirror whose shape was a reverse cone with no top was added between the Fresnel lens and solar cells to increase the acceptance angle of the solar module. A design example was given, and analyzed by optical simulation with the software of Solidworks and Tracepro. The conclusion indicates the removable secondary mirror can increase the acceptance angle and improve the irradiance uniformity of the focus spot.

    Solar energy is a bountiful renewable energy resource: the energy in the sunlight that reaches Earth in an hour exceeds the energy consumed by all of humanity in a year.(1) While the phrase “solar energy conversion” probably brings photovoltaic (PV) cells to mind first, PV is not the only option for generating electricity from sunlight. Another promising technology for solar energy conversion is solar–thermal conversion, commonly referred to as concentrating solar power (CSP).(2) The first utility-scale CSP plants were constructed in the 1980s, but in the two decades that followed, CSP saw little expansion.(3, 4) More recent years, however, have seen a CSP renaissance due to unprecedented growth in the adoption of CSP.(3, 5) Photographs of two operating CSP plants, a parabolic trough collector plant and a central receiver (or “power tower”), are shown here.

    In addition to wind and photovoltaic power, concentrating solar thermal power (CSP) will make a major contribution to electricity provision from renewable energies. Drawing on almost 30 years of operational experience in the multi-megawatt range, CSP is now a proven technology with a reliable cost and performance record. In conjunction with thermal energy storage, electricity can be provided according to demand. To date, solar thermal power plants with a total capacity of 1.3 GW are in operation worldwide, with an additional 2.3 GW under construction and 31.7 GW in advanced planning stage. Depending on the concentration factors, temperatures up to 1000°C can be reached to produce saturated or superheated steam for steam turbine cycles or compressed hot gas for gas turbine cycles. The heat rejected from these thermodynamic cycles can be used for sea water desalination, process heat and centralized provision of chilled water. While electricity generation from CSP plants is still more expensive than from wind turbines or photovoltaic panels, its independence from fluctuations and daily variation of wind speed and solar radiation provides it with a higher value. To become competitive with mid-load electricity from conventional power plants within the next 10-15 years, mass production of components, increased plant size and planning/operating experience will be accompanied by technological innovations. On 30 October 2009, a number of major industrial companies joined forces to establish the so-called DESERTEC Industry Initiative, which aims at providing by 2050 15 per cent of European electricity from renewable energy sources in North Africa, while at the same time securing energy, water, income and employment for this region. Solar thermal power plants are in the heart of this concept.

    For developing laser process technology by interaction between substance and photon, the present state, system, R and D issues and proposal of such technology were summarized. Development of the photon technology aims at the modification of bonding conditions of substances by quantum energy of photon, and the new process technology for generating ultra- high temperature and pressure fields by concentrating photon on a minute region. Photon technology contributes to not only the conventional mechanical and thermal forming and removal machining but also function added machining (photon machining) in quantum level and new machining technology ranging from macro- to micro-machining, creating a new industrial field. This technology extends various fields from the basis of physics and chemistry to new bonding technology. Development of a compact high-quality high-power high-efficiency photon source, and advanced photon transmission technology are necessary. The basic explication of an unsolved physicochemical phenomenon related to photon and substance, and development of related application technologies are essential. 328 refs., 147 figs., 13 tabs.

    Full text: Two research initiatives by Pandion Systems, funded by the US Bureau of Ocean Energy Management, Regulation, and Enforcement (BOEMRE), are addressing the enormous challenges of conducting offshore wind-wildlife risk/impact studies by providing new wildlife sensing technologies that surmount some of the limitations of previous techniques. Both initiatives rest on the shoulders of pioneering European studies and experience. One entails the development of a remote-operating acoustic/thermographic detector. This device, designed with input from the Danish National Environmental Research Institute (NERI) and Cornell Laboratory of Ornithology (CLO), will provide species-specific occurrence data, as well as flight altitude estimation, for vocalizing flying wildlife that flies within a detection beam that corresponds roughly to the rotor swept zone of a single, commercial marine wind turbine. While the detection beam is small and limitations exist for silently flying animals, this device will be capable of providing information on bats and on federally-listed bird species that has been difficult or impossible to achieve with other methods. A preliminary version of this device was developed in 2009-2010 in a BOEMRE-funded pilot study, and a sea-worthy device is currently being developed, scheduled for initial deployment on the US Atlantic Outer Continental Shelf (AOCS) in summer, 2011. A second initiative is targeted at developing a high-definition aerial survey protocol capable of providing a safe, cost-effective, reproducible snapshot of bird, marine mammal, and sea turtle distribution on the entire AOCS. This research, being conducted with a team of technologists and biologists including scientists from the British Trust for Ornithology (BTO), entails conducting a series of pilot experiments in spring, 2011 with a variety of different aircraft, cameras, flight altitudes, and image resolutions, to determine optimum protocols for the large-scale surveys.

    Integral to photovoltaics is the need to provide improved economic viability. To achieve this goal, photovoltaic technology has to be able to harness more light at less cost. A large variety of concentrating photovoltaic concepts has provided cause for pursuit. To obtain a detailed profitability analysis, a flexible evaluation is crucial for benchmarking the cost-performance of this variety of concentrating photovoltaic concepts. To save time and capital, a way to estimate the cost-performance of a complete solar energy system is to use computer aided modeling. In this work a benchmark tool is introduced based on a modular programming concept. The overall implementation is done in MATLAB whereas Advanced Systems Analysis Program (ASAP) is used for ray tracing calculations. This allows for a flexible and extendable structuring of all important modules, namely an advanced source modeling including time and local dependence, and an advanced optical system analysis of various optical designs to obtain an evaluation of the figure of merit. An important figure of merit: the energy yield for a given photovoltaic system at a geographical position over a specific period, can be calculated.

    1989-01-01

    The Solar Concentrator Advanced Development Project has successfully designed, fabricated, and tested a full scale prototypical solar dynamic concentrator for space station applications. A Truss Hexagonal Panel reflector was selected as a viable solar concentrator concept to be used for space station applications. This concentrator utilizes a modular design approach and is flexible in attainable flux profiles and assembly techniques. The detailed design of the concentrator, which included structural, thermal and optical analysis, identified the feasibility of the design and specific technologies that were required to fabricate it. The needed surface accuracy of the reflectors surface was found to be very tight, within 5 mrad RMS slope error, and results in very close tolerances for fabrication. To meet the design requirements, a modular structure composed of hexagonal panels was used. The panels, made up of graphite epoxy box beams provided the strength, stiffness and dimensional stability needed. All initial project requirements were met or exceeded by hardware demonstration. Initial testing of structural repeatability of a seven panel portion of the concentrator was followed by assembly and testing of the full nineteen panel structure. The testing, which consisted of theodolite and optical measurements over an assembly-disassembly-reassembly cycle, demonstrated that the concentrator maintained the as-built contour and optical characteristics. The facet development effort within the project, which included developing the vapor deposited reflective facet, produced a viable design with demonstrated optical characteristics that are within the project goals.

    The article describes a five-year period of Technology Enhanced Learning (TEL) implementation at the Faculty of Materials Science and Technology (MTF) in Trnava. It is a part of the challenges put forward by the 7th Framework Programme (ICT research in FP7) focused on "how information and communication technologies can be used to support learning and teaching". The empirical research during the years 2006-2008 was focused on technology-driven support of teaching, i. e. the development of VLE (Virtual Learning Environment) and the development of database applications such as instruments developed simultaneously with the information support of the project, and tested and applied directly in the teaching of bachelor students. During this period, the MTF also participated in the administration of the FP7 KEPLER project proposal in the international consortium of 20 participants. In the following period of 2009-2010, the concept of educational activities automation systematically began to develop. Within this concept, the idea originated to develop a universal multi-purpose system BIKE based on the batch processing knowledge paradigm. This allowed to focus more on educational approach, i.e. TEL educational-driven and to finish the programming of the Internet application - network for feedback (communication between teachers and students). Thanks to this specialization, the results of applications in the teaching at MTF could gradually be presented at the international conferences focused on computer-enhanced engineering education. TEL was implemented at a detached workplace and four institutes involving more than 600 students-bachelors and teachers of technical subjects. Four study programmes were supported, including technical English language. Altogether, the results have been presented via 16 articles in five countries, including the EU level (IGIP-SEFI).

    酒精高浓度发酵能够提高发酵醪液含酒分,可以节省酒精蒸馏蒸汽消耗量,减少酒精废醪液排放量,提高设备利用率,日益受到酒精生产企业的重视。目前糖蜜酒精生产发酵含酒分普遍偏低,糖蜜高浓度发酵面临很大困难,笔者认为主要原因是糖蜜中的灰分和胶体等杂质含量不断增高,会抑制酵母的繁殖和发酵,影响糖蜜高浓度发酵酒精。对糖蜜进行澄清处理是实现糖蜜酒精浓醪发酵的快捷途径,通过对糖蜜快速热澄清处理,得到糖蜜高浓度发酵酒精,与传统糖蜜酸化后发酵酒精相比,发酵含酒分明显提高,发酵成熟醪锤度降低。%High concentrations of alcohol fermentation could improve fermentation ethanol contents, save alcohol distillation steam consumption, reduce waste liquor of alcohol, and improve the utilization rate of equipment. It had been paid more attention by alcohol production enterprises. The content of alcohol fermentation of molasses alcohol was generally low, so the molasses high concentration fermentation was facing great difficulties. The author thought that the main reason was ash and colloid impurities content in molasses increasing continuously, which could inhibit yeast growth and fermentation and affect the molasses fermentation of high concentration alcohol. The rapid clarification of molasses was a quick way to realize high concentration fermentation of molasses.The high concentration fermentation of molasses alcohol was obtained through the molasses rapid thermal clarification, compared with the traditional acidification fermentation of molasses alcohol, molasses alcohol fermentation liquor with clarification obviously improved, and mature fermented mash brix reduced.

    Concentrated Photovoltaics (CPV), once a niche technology, has now reached the maturity and reliability for large scale power generation. Especially in regions where temperatures are very high, the use of high efficiency triple junction solar cells with concentrating optics allows stable energy yield. Thus CPV can be seen as complementary and not in concurrence with silicon photovoltaics. The state of the art, the advantages and limitations of this technology will be shown. Among the main advantages of CPV is the possibility of a much higher energy supply, when compared to silicon photovoltaics, both comparing CPV and silicon with same area or the same installed power. The use of recycled and recyclable materials allows a more environmentally friendly production. The possibility to couple CPV with desalination facilities, energy storage will be analysed. As an example a case study of a CPV installation in Northern Italy is discussed. Here the use of mature technologies, derived from automotive and lighting sectors resulted in a simple and efficient module.

    2007-09-01

    The Levelized Cost of Energy (LCOE) takes into account more than just the cost of power output. It encompasses product longevity, performance degradation and the costs associated with delivering energy to the grid tie point. Concentrator optical design is one of the key components to minimizing the LCOE, by affecting conversion efficiency, acceptance angle and the amount of energy concentrated on the receiver. Optical systems for concentrators, even those at high concentrations ( >350X) can be designed by straightforward techniques, and will operate under most circumstances. Adding requirements for generous acceptance angles, non-destructive off-axis operation, safety and high efficiency however, complicate the design. Furthermore, the demands of high volume manufacturing, efficient logistics, minimal field commissioning time and low cost lead to quite complicated, system level design trade-offs. The technology which we will discuss features an array of reflective optics, scaled to be fabricated by techniques used in the automotive industry. The design couples a two-element imaging system to a non-imaging total internal reflection tertiary in a very compact design, with generous tolerance margins. Several optical units are mounted in a housing, which protects the optics and assists with dissipating waste heat. This paper outlines the key elements in the design of SolFocus concentrator optics, and discusses tradeoffs and experience with various design approaches.

    Photovoltaic concentration systems that redirect sunlight falling on a surface to a smaller solar-cell surface concentrating the intensity of sunlight many times are examined. It is noted that solar cells for concentrating systems must be designed for low internal resistance as well as for high sunlight intensities. Two designs of silicon cells are presented that perform well at high concentrations; these are interdigitated back-contact cells and vertical multijunction cells. Attention is given to heat tapping of reemitted light.

  3. Concentrators Enhance Solar Power Systems

    Science.gov (United States)

    2013-01-01

    "Right now, solar electric propulsion is being looked at very seriously," says Michael Piszczor, chief of the photovoltaic and power technologies branch at Glen Research Center. The reason, he explains, originates with a unique NASA mission from the late 1990s. In 1998, the Deep Space 1 spacecraft launched from Kennedy Space Center to test a dozen different space technologies, including SCARLET, or the Solar Concentrator Array with Refractive Linear Element Technology. As a solar array that focused sunlight on a smaller solar cell to generate electric power, SCARLET not only powered Deep Space 1 s instruments but also powered its ion engine, which propelled the spacecraft throughout its journey. Deep Space 1 was the first spacecraft powered by a refractive concentrator design like SCARLET, and also utilized multi-junction solar cells, or cells made of multiple layers of different materials. For the duration of its 38-month mission, SCARLET performed flawlessly, even as Deep Space 1 flew by Comet Borrelly and Asteroid Braille. "Everyone remembers the ion engine on Deep Space 1, but they tend to forget that the SCARLET array powered it," says Piszczor. "Not only did both technologies work as designed, but the synergy between the two, solar power and propulsion together, is really the important aspect of this technology demonstration mission. It was the first successful use of solar electric propulsion for primary propulsion." More than a decade later, NASA is keenly interested in using solar electric propulsion (SEP) for future space missions. A key issue is cost, and SEP has the potential to substantially reduce cost compared to conventional chemical propulsion technology. "SEP allows you to use spacecraft that are smaller, lighter, and less costly," says Piszczor. "Even though it might take longer to get somewhere using SEP, if you are willing to trade time for cost and smaller vehicles, it s a good trade." Potentially, SEP could be used on future science missions

    Economic processing of lignocellulosic biomass requires handling the biomass at high solids concentration. This creates challenges because concentrated biomass behaves as a Bingham-like material with large yield stresses. Here we employ torque rheometry to measure the rheological properties of concentrated lignocellulosic biomass (corn stover). Yield stresses obtained...

    Accurate determination of lipid concentrations is an obligatory routine in a research laboratory engaged in studies using this class of biomaterials. For phospholipids, this is frequently accomplished using the phosphate assay (Bartlett, G.R. Phosphorus Assay in Column Chromatography. J. Biol. Chem. 234, 466-468, 1959). Given the purity of the currently commercially available synthetic and isolated natural lipids, we have observed that determination of the dry weight of lipid stock solutions provides the fastest, most accurate, and generic method to assay their concentrations. The protocol described here takes advantage of the high resolution and accuracy obtained by modern weighing technology. We assayed by this technique the concentrations of a number of phosphatidylcholine samples, with different degrees of acyl chain saturation and length, and in different organic solvents. The results were compared with those from Bartlett assay, (31)P NMR, and Langmuir compression isotherms. The data obtained show that the gravimetric assay yields lipid concentrations with a resolution similar or better than obtained by the other techniques.

    Taking 0203 working face of Xinyang coal mine as engineering background,and through the theoretical analy-sis and numerical simulation,the pressure characteristics of gob-side entry retaining roadway under caving method and filling method are contrasted and analyzed to further explore the deformation law of gob-side entry retaining roadway after total back-filling. Combined with the basic mechanical properties of high concentration of cemented filling materials, the basic roadway supporting and the strengthening support mode are designed and applied into the practical production. The application showed that the gob-side entry retaining had less deformation after backfilling with deformation rate of around 8%. The roadway roof kept complete without any large caving,and no coal wall spalling appeared at roadway. Single support or combined support of anchor rod,anchor rope,metal mesh at roadway is reliable and reasonable. The high concentration of cemented filling mining technique with gob-side entry retaining is simple and feasible. The gob-side entry retaining roadway is formed naturally after filling gob,and the fire,gas accumulation and other disasters can be effectively avoided. Thus,it has a broad application pros-pect.%以新阳煤矿10203充填工作面为研究背景,通过理论分析和数值模拟,对垮落法和充填法开采下的采空区沿空留巷巷道矿山压力进行了对比分析,进一步探究了采空区全部充填后沿空留巷巷道的变形规律。结合高浓度胶结充填体的力学特性,设计了沿空留巷巷内基本支护、加强支护的方式,并将其运用于生产实践。井下应用表明:充填开采后的沿空留巷巷道围岩变形量较小,其变形率仅为8%左右;巷道顶板较为完整,没有发生大的冒落,且巷道煤壁无片帮现象发生;巷道内采用的锚杆、锚索、金属网、单体支柱联合支护安全可靠,支护合理。煤矿高浓度胶结充填开采沿

    Tobacco products are extensively used throughout the world and the most consumed are cigarettes, cigars and narghile. The damaging effects that these products cause to human health are discussed worldwide and many researches are performed with the aim of relating the use of these products with various diseases. Brazil is the largest exporter and second largest producer of tobacco worldwide, according to the crop year 2009/2010 production. The tobacco plant (Nicotiana tabacum L.) is used to manufacture all derivatives and the chemical composition of the resulting tobacco varies with the type of tobacco leaves, how they are grown, the region where they are cultivated, the characteristics of preparation and the temperature variations resulting from the tobacco incomplete combustion. There is lack of information about the chemical and radiological characterization of the tobacco plant both in international and Brazilian literature. Thus a project was established with the objectives of characterizing chemically and radiologically the three varieties most cultivated in Brazil of Nicotiana tobacum L., Virginia, Burley and Common; this paper presents the preliminary results of {sup 210}Pb concentrations for the Burley variety. Plants from this variety were cultivated in pots with organic substrate and fertilizer and in a small farm in natural conditions. The entire plant was analyzed, the organic substrates, the fertilizers and the soil. The results obtained presented higher values for {sup 210}Pb in leaves when compared with the other parts of the plant. Comparing the three study areas the highest results of {sup 210}Pb concentration were obtained in the plants cultivated in the urban area probably due to its atmospheric deposition. (author)

    Peatlands in Zoige Plateau contains more than half of peatland carbon stock in China. This part of carbon is losing with climate change through dissolved organic carbon (DOC) export and carbon dioxide (CO2) emissions, both of which are vulnerable to the environmental changes, especially on the Zoige Plateau with a pace of twice the observed rate of global climate warming. This research aimed to understand how climate change including soil warming, rainfall reduction and water table change affect CO2 emissions and whether the trends of changes in CO2 emission are consistent with those of pore water DOC concentration. A mesocosm experiment was designed to investigate the CO2 emission and pore water DOC during the growing seasons of 2009-2010 under scenarios of passive soil warming, 20% rainfall reduction and changes to the water table levels. The results showed a positive relationship between CO2 emission and DOC concentration. For single factor effect, we found no significant relationship between water table and CO2 emission or DOC concentration. However, temperature at 5 cm depth was found to have positive linear relationship with CO2 emission and DOC concentration. The combined effect of soil warming and rainfall reduction increased CO2 emission by 96.8%. It suggested that the drying and warming could stimulate potential emission of CO2. Extending this result to the entire peatland area in Zoige Plateau translates into 0.45 Tg CO2 emission per year over a growing season. These results suggested that the dryer and warmer Zoige Plateau will increase CO2 emission. We also found the contribution rate of DOC concentration to CO2 emission was increased by 12.1% in the surface layer and decreased by 13.8% in the subsurface layer with combined treatment of soil warming and rainfall reduction, which indicated that the warmer and dryer environmental conditions stimulate surface peat decomposition process.

    Climate change and global warming transpire due to several factors. Among them is deforestation which occur mostly in developing countries including Malaysia where forested areas are converted to other land use for tangible economic returns and to a smaller extent, as subsistence for local communities. As a cause for concern, efforts have been taken by the World Resource Institute (WRI) and World Wildlife Fund (WWF) to monitor forest loss using geospatial technology - interpreting time-based remote sensing imageries and producing statistics of forested areas lost since 2001. In Peninsular Malaysia, the Forestry Department of Peninsular Malaysia(FDPM) has conducted forest cover mapping for the region using the same technology since 2011, producing GIS maps for 2009-2010,2011-2012,2013-2014 and 2015. This paper focuses on the comparative study of the results generated from WRI,WWF and FDPM interpretations between 2010 and 2015, the methodologies used, the similarities and differences, challenges and recommendations for future enhancement of forest cover mapping technique.

    Planar waveguides are useful to transport, concentrate and distribute light uniformly over large dimensions. Their capacity to collect and gather light efficiently over a large distance is interesting for many applications, like backlighting and solar concentration. For these reasons, the possibility of making them even more efficient could be of considerable interest for the community. The observation of the ray path inside a graded-index (GRIN) fiber inspired the development of a similar technology inside planar waveguides. In this Letter, we show that it has the potential to dramatically increase the efficiency of planar waveguide-based solar concentrators or backlighting using GRIN planar waveguides.

    There are limited data describing pollutant levels inside homes that burn solid fuel within developed country settings with most studies describing test conditions or the effect of interventions. This study recruited homes in Ireland and Scotland where open combustion processes take place. Open combustion was classified as coal, peat, or wood fuel burning, use of a gas cooker or stove, or where there is at least one resident smoker. Twenty-four-hour data on airborne concentrations of particulate matter <2.5 mu in size (PM{sub 2.5}), carbon monoxide (CO), endotoxin in inhalable dust and carbon dioxide (CO{sub 2}), together with 2-3 week averaged concentrations of nitrogen dioxide (NO{sub 2}) were collected in 100 houses during the winter and spring of 2009-2010. The geometric mean of the 24-h time-weighted-average (TWA) PM{sub 2.5} concentration was highest in homes with resident smokers (99 mu/m3- much higher than the WHO 24-h guidance value of 25 mu/m3). Lower geometric mean 24-h TWA levels were found in homes that burned coal (7 mu/m3) or wood (6 mu/m3) and in homes with gas cookers (7 mu/m3). In peat-burning homes, the average 24-h PM{sub 2.5} level recorded was 11 mu/m3.

    Research scope: The scope of the project is to study technological implementation processes by using Weick's sensemaking concept (Weick, 1995). The purpose of using a social constructivist approach to investigate technological implementation processes is to find out how new technologies transform......, Orlikowski 2000). Viewing the use of technology as a process of enactment opens up for investigating the social processes of interpreting new technology into the organisation (Orlikowski 2000). The scope of the PhD project will therefore be to gain a deeper understanding of how the enactment of new...... & Brass, 1990; Kling 1991; Orlikowski 2000). It also demonstrates that technology is a flexible variable adapted to the organisation's needs, culture, climate and management philosophy, thus leading to different uses and outcomes of the same technology in different organisations (Barley 1986; 1990...

    Limited information is available on the seroprevalence of chikungunya virus (CHIKV) infection and maternal-fetal transmission incidence of CHIKV and dengue virus (DENV) infections during the 2008-2009 CHIKV outbreak in southern Thailand. A community-based post-epidemic seroprevalence study was conducted in parturient women admitted to the Thepa District Hospital in Songkhla Province, Thailand, for delivery from November 2009 to May 2010. The women were tested for chikungunya (CHIK) IgM/IgG and dengue (DEN) IgM/IgG. Cord blood samples were also tested for CHIK IgM or DEN IgM in women who tested positive for CHIK IgM or DEN IgM, respectively. The seroprevalence of CHIKV infection (CHIK IgM or IgG positive) was 227/319 (71·2%) with pre-outbreak seroprevalence (IgM-/IgG+) of 43·6% and the seroprevalence of DENV infection was 288/319 (90·3%). Complications during pregnancy, newborn outcomes and congenital anomalies were not different in those who had recent, remote or no CHIKV infections. None of the newborns whose mothers were CHIK or DEN IgM positive had cord blood positive for both CHIK and DEN IgM. In conclusion, both CHIKV and DENV are endemic in southern Thailand; during the recent CHIKV outbreak CHIK seroprevalence increased from 43·6% to 71·2%.

    Full Text Available The study provides data on the prevalence of Listeria monocytogenes in ready-to-eat food samples collected by Lombardy region health authorities and analyzed by Department of Food Microbiology, Istituto Zooprofilattico Sperimentale della Lombardia e dell’Emilia Romagna. From the total of 503 food samples analyzed, the pathogen was detected in 85 (16,9%. In particular it was highlighted in 8/152 (5,3% meat products, in 5/245 (2% dairy products and in 42/106 (39,6% fishery products. Given the considerable public health implications, the study confirms that a well-planned program of listeriosis surveillance should be enforced to suitably estimate the burden of disease and to prevent foodborne outbreaks.
