    Full Text Available Methyl tertiary butyl ether (MTBE—A well known gasoline additive substituting for lead alkyls—causes lipid disorders and liver dysfunctions in animal models. However, whether MTBE exposure is a risk factor for non-alcoholic fatty liver disease (NAFLD remains uncertain. We evaluate the possible relationship between MTBE exposure and the prevalence of NAFLD among 71 petrol station attendants in southern China. The personal exposure concentrations of MTBE were analyzed by Head Space Solid Phase Microextraction GC/MS. NAFLD was diagnosed by using abdominal ultrasonography according to the guidelines for the diagnosis and treatment of NAFLD suggested by the Chinese Hepatology Association. Demographic and clinical characteristics potentially associated with NAFLD were investigated. Mutivariate logistic regression analysis was applied to measure odds ratios and 95% confidence intervals (CI. The result showed that the total prevalence of NAFLD was 15.49% (11/71 among the study subjects. The average exposure concentrations of MTBE were 292.98 ± 154.90 μg/m3 and 286.64 ± 122.28 μg/m3 in NAFLD and non-NAFLD groups, respectively, and there was no statistically significant difference between them (p > 0.05. After adjusting for age, gender, physical exercise, body mass index (BMI, systolic blood pressure (SBP, diastolic blood pressure (DBP, alanine aminotransferase (ALT, white blood cell (WBC, total cholesterol (TC, triglycerides (TG, low-density lipoprotein (LDL, and high-density lipoprotein (HDL, the odds ratios were 1.31 (95% CI: 0.85–1.54; p > 0.05, 1.14 (95% CI: 0.81–1.32; p > 0.05, 1.52 (95% CI: 0.93–1.61; p > 0.05 in the groups (including men and women with exposure concentrations of MTBE of 100–200 μg/m3, 200–300 μg/m3, and ≥300 μg/m3, respectively, as compared to the group (including men and women ≤100 μg/m3.

    Full Text Available Methyl tertiary butyl ether (MTBE, a well known gasoline additive, is used in China nationwide to enhance the octane number of gasoline and reduce harmful exhaust emissions, yet  little is known regarding the potential health risk associated with occupational exposure to MTBE in petrol stations. In this study, 97 petrol station attendants (PSAs in southern China were recruited for an assessment of the health risk associated with inhalation exposure to MTBE. The personal exposure levels of MTBE were analyzed by Head Space Solid Phase Microextraction GC/MS, and the demographic characteristics of the PSAs were investigated. Cancer and non-cancer risks were calculated with the methods recommended by the United States Environmental Protection Agency. The results showed that the exposure levels of MTBE in operating workers were much higher than among support staff (p < 0.01 and both were lower than 50 ppm (an occupational threshold limit value. The calculated cancer risks (CRs at the investigated petrol stations was 0.170 to 0.240 per 106 for operating workers, and 0.026 to 0.049 per 106 for support staff, which are below the typical target range for risk management of 1 × 10−6 to 1 × 10−4; The hazard quotients (HQs for all subjects were <1. In conclusion, our study indicates that the MTBE exposure of PSAs in southern China is in a low range which does not seem to be a significant health risk.

    This cross-sectional study was aimed at reconstructing the exposure to gasoline in 102 petrol station attendants by environmental and biological monitoring of benzene, toluene, ethylbenzene and xylene (BTEX) and biomonitoring of methyl tert-butyl ether (MTBE). Airborne BTEX were higher for manual refuelers than self-service assistants and were highly correlated with each other. Significant relationships were found between airborne BTX and the corresponding urinary solvents (U-BTX) and beween airborne B and urinary MTBE (U-MTBE). Smokers eliminated higher values of U-B, trans,trans-muconic (t,t-MA) and S-phenylmercapturic (S-PMA) acids but not U-MTBE. All these biomarkers were, however, significantly raised during the shift, independently from smoking. Linear regression confirmed that occupational exposure was a main predictor of U-MTBE, U-B and S-PMA values, both the latter confounded by smoking habits. The study supports the usefulness of biomonitoring even at low exposure levels.

    2013-04-01

    Former petrol stations are, possibly, potential hydrocarbon contaminated soil areas due to leakage in Underground Storage Tanks and fuel dispensing activities. Volatile Organic Compounds (VOCs) in gasoline, like benzene and semi-volatile organics in diesel, are carcinogenic and very toxic substances which can involve a serious risk for ecosystem and human health. Based on Electrical Resistivity Tomography 2D results from a previous work, there have been selected three potentially contaminated goal areas in a former petrol station located in SE Spain in order to obtain soil samples by drilling and to assess the gasoline and diesel contamination. A special sampling design was carried out and soil samples for VOCs were preserved at field with a KCl solution to minimize volatilization losses. It had been chosen Headspace-GC-MS as the better technique to quantify individual VOCs and GC-FID to get a Total Petroleum Hydrocarbon (TPH) assessment after a solid/fluid pressurized extraction. The physicochemical characterization of the subsoil was performed to know how humidity, clay content or pH data could be related to the presence of hydrocarbons in the soil samples. Results show that VOCs concentrations in subsoil samples of the petrol station are around ppb levels. TPH ranged between 17 mg/kg soil and 93 mg/kg soil (ppm levels) what involves diesel and gasoline leaks due to these detected residual concentrations in the subsoil. The maximum value was found at 6 m deep in an intermediate zone between Underground Storage Tanks positions (located at 4 m deep). Therefore, these results confirm that organic compounds transference with strong vertical component has taken place. It has been observed that humidity minimum values in the subsoil are related to TPH maximum values that could be explained because of the vapour phase and the retention of hydrocarbon in soil increases when humidity goes down. Adsorption of hydrocarbons in the subsoil tend to be pH-dependent and clay

    With the Oil and Gas Law No. 22 of 2001, national and foreign private enterprises can invest in all sectors of Oil and Gas in Indonesia. In anticipation of this free competition, Pertamina, as a state-owned enterprises, which previously had monopolized the oil and gas business activities in Indonesia, should be able to improve services as well as the efficiency in order to compete in the free market, especially in terms of cost efficiency of fuel distribution to gas station (SPBU). To optimize the distribution activity, it is necessary to design a scheduling system and its fuel delivery routes daily to every SPBU. The determination of routes and scheduling delivery of fuel to the SPBU can be modeled as a Petrol Station Replenishment Problem (PSRP) with the multi-depot, multi-product, time windows and split deliveries, which in this study will be completed by the Tabu Search algorithm (TS). This study was conducted in the area of Bandung, the capital of West Java province, which is a big city and the neighboring city of Jakarta, the capital city of Indonesia. By using the fuel delivery data for one day, the results showed a decrease of 16.38% of the distance of the route compared to the current conditions, which impacted on the reduction of distribution costs and decrease the number of total trips by 5.22% and 3.83%.

    Full Text Available In large cities, fuel consumption is growing rapidly, and therefore the number of filling stations. And they are a source of anthropogenic impact on the environment and represent current scientific and practical task, because recently no research was conducted into the optimization of monitoring systems in the construction of gas station storage tanks, and no activity on replacing the obsolete design with new storage tanks. In this regard, much attention should be paid to the creation of geo-environmental systems integrated assessment of the environment, as well as modeling and forecasting various negative situations. In the modern world, the creation of such systems is possible with the help of modern computer tools such as geographic information systems.

  18. Methodology for the detection of contamination by hydrocarbons and further soil sampling for volatile and semi-volatile organic enrichment in former petrol stations, SE Spain

    2012-01-01

    Full Text Available The optimal detection and quantification of contamination plumes in soil and groundwater by petroleum organic compounds, gasoline and diesel, is critical for the reclamation of hydrocarbons contaminated soil at petrol stations. Through this study it has been achieved a sampling stage optimization in these scenarios by means of the location of potential contamination areas before sampling with the application of the 2D electrical resistivity tomography method, a geophysical non destructive technique based on resistivity measurements in soils. After the detection of hydrocarbons contaminated areas, boreholes with continuous coring were performed in a petrol station located in Murcia Region (Spain. The drillholes reached depths down to 10 m and soil samples were taken from each meter of the drilling. The optimization in the soil samples handling and storage, for both volatile and semi-volatile organic compounds determinations, was achieved by designing a soil sampler to minimize volatilization losses and in order to avoid the manual contact with the environmental samples during the sampling. The preservation of soil samples was performed according to Europe regulations and US Environmental Protection Agency recommendations into two kinds of glass vials. Moreover, it has been taken into account the determination techniques to quantify the hydrocarbon pollution based on Gas Chromatography with different detectors and headspace technique to reach a liquid-gas equilibrium for volatile analyses.

    Exposure to benzene promotes oxidative stress through the production of ROS, which can damage biological structures with the formation of new metabolites which can be used as markers of oxidant/antioxidant imbalance. This study aims to assess modifications in circulating levels of advanced oxidation protein products (AOPP), advanced glycation end-products (AGE) and serum reactive oxygen metabolites (ROMs) in a group of gasoline station attendants exposed to low-dose benzene and to evaluate the influence of antioxidant food intake on these biomarkers of oxidative stress. The diet adopted by the population examined consisted of compounds belonging to the classes of terpenoids, stilbenes and flavonoids, notably resveratrol, lycopene and apigenin. Ninety one gasoline station attendants occupationally exposed to benzene and 63 unexposed male office workers were recruited for this study. Urinary trans, trans-muconic acid (t,t-MA) concentration, determined to assess individual exposure level, resulted significantly higher in exposed workers. In subjects exposed to benzene, we observed a significant increase (p ROMs and AOPP levels, which were also negatively correlated with fruit and vegetables consumption. By contrast, AGE did not show a significant increase and consequently any relation with antioxidant food intake. Only ROMs, representing a global biomarker of oxidative status, resulted correlated to t,t-MA levels (p ROMs increment in subject exposed to benzene. These biomarkers may be useful for screening purposes in gasoline station workers and other subjects exposed to low-dose benzene. Moreover, a diet rich in fruits and vegetables demonstrated an inverse association with the levels of oxidative stress markers, suggesting a protective role of antioxidant food intake in workers exposed to oxidant agents.

    Full Text Available The purpose of the present study was to investigate possible methods to enhance the rate of aerobic biodegradation of hydrocarbons (ex-situ treatments. In this work, the bioremediation processes were applied to a sandy soil with a high level of contamination originated from the leakage of a diesel oil underground storage tank at a petrol station. Laboratory scale experiments (Bartha biometer flasks were used to evaluate the biodegradation of the diesel oil. Enhancement of biodegradation was carried out through biostimulation (addition of nitrogen and phosphorus solutions or Tween 80 surfactant and bioaugmentation (bacterial consortium isolated from a landfarming system. To investigate interactions between optimizing factors, and to find the right combination of these agents, the study was based on full factorial experimental design. Efficiency of biodegradation was simultaneously measured by two methods: respirometric (microbial CO2 production and gas chromatography. Acute toxicity tests with Daphnia similis were applied for examination of the efficiency of the processes in terms of the generation of less toxic products. Results showed that all bioremediation strategies enhanced the natural bioremediation of the contaminated soil and the best results were obtained when treatments had nutritional amendment. Respirometric data indicated a maximum hydrocarbon mineralization of 19.8%, obtained through the combination of the three agents, with a total petroleum hydrocarbons (TPH removal of 45.5% in 55 days of treatment. At the end of the experiments, two predominant bacteria species were isolated and identified (Staphylococcus hominis and Kocuria palustris.O objetivo do presente estudo foi investigar possíveis métodos para aumentar a taxa de biodegradação aeróbia de hidrocarbonetos (tratamentos ex-situ.

    1996-12-01

    A monitoring survey of filling station attendants aimed at identifying sources of variability of exposure to benzene and other aromatics was carried out. Concurrent samples of the worker`s breathing zone air, atmospheric air in the service station proximity, and gasoline were collected, along with information about daily workloads and other exposure-related factors. Benzene personal exposure was characterised by a small between-worker variability and a predominant within-worker variance component. Such elevated day-to-day variability yields to imprecise estimates of mean personal exposure. Almost 70% of the overall personal exposure variance was explained by a model including daily benzene from dispensed fuel, presence of a shelter over the refueling area, amount of fuel supplied to the station if a delivery occurred, and background atmospheric benzene concentration.

    2014-01-01

    Full Text Available Background: Since petrol is combustible and smoking is banned at the petrol pumps, it may be predicted that use of smokeless tobacco is more prevalent among the petrol fillers. Also, smokeless tobacco is a major risk factor for developing oral potentially malignant disorders. The present study was conducted to determine the tobacco use, body mass index (BMI, and potentially malignant disorders among a cohort of petrol fillers and also to evaluate the interaction of tobacco use and BMI with the presence of potentially malignant disorders. Settings and Design: The study was conducted at 45 petrol stations located at Pimpri-Pune, India. A descriptive study design was used. Materials and Method: Four hundred and ten petrol fillers aged 17-64 years participated in the study. General information and tobacco history was obtained by interview. Height and weight were recorded to obtain BMI. Oral examination was conducted to identify the potentially malignant disorders.

    2011-02-01

    Full Text Available A measurement program designed to evaluate health impacts or benefits of using ethanol blend petrol examined exhaust and evaporative emissions from 21 vehicles representative of the current Australian light duty petrol (gasoline vehicle fleet using a composite urban emissions drive cycle. The fuels used were unleaded petrol (ULP, ULP blended with either 5% ethanol (E5 or 10% ethanol (E10. The resulting data were combined with inventory data for Sydney to determine the expected fleet emissions for different uptakes of ethanol blended fuel. Fleet ethanol compatibility was estimated to be 60% for 2006, and for the air quality modelling it was assumed that in 2011 over 95% of the fleet would be ethanol compatible. Secondary organic aerosol (SOA formation from ULP, E5 and E10 emissions was studied under controlled conditions by the use of a smog chamber. This was combined with meteorological data from Sydney for February 2004 and the emission data (both measured and inventory data to model pollutant concentrations in Sydney’s airshed for 2006 and 2011. These concentrations were combined with the population distribution to evaluate population exposure to the pollutant. There is a health benefit to the Sydney population arising from a move from ULP to ethanol blends in spark-ignition vehicles. Potential health cost savings for Urban Australia (Sydney, Melbourne, Brisbane and Perth are estimated to be A$39 million (in 2007 dollars for a 50% uptake (by ethanol compatible vehicles of E10 in 2006 and $42 million per annum for a 100% take up of E10 in 2011. Over 97% of the estimated health savings are due to reduced emissions of PM2.5 and consequent reduced impacts on mortality and morbidity (e.g., asthma, cardiovascular disease. Despite more petrol-driven vehicles predicted for 2011, the quantified health impact differential between ULP and ethanol fuelled vehicles drops from 2006 to 2011. This is because modern petrol vehicles, with lower emissions than

    Full Text Available Oil industry, one of the most prominent figures of energy market of Turkey, is also considered among driving powers behind the country’s economy. The competition among petrol stations in oil industry is quite profound both in local and global dimensions. It is of vital importance for petrol stations to set their strategies of brand positioning so that they can ensure consumer loyalty and brand continuity and attract new consumers. This study aims at identifying consumer perception regarding petrol stations through multidimensional scaling analysis in order to determine how petrol stations position their brands. To that end, the consumers were asked to evaluate the similarities and differences among five most known petrol station brands in Turkey with regards to some dimensions in consequence of the data acquired from the literature research. Thus, stations with great resemblance and those with no relevance were determined as a result of the study. Multidimensional scaling analysis allows petrol stations to conduct their own self-assessments in consideration of their positions in the market. It was found that for nearly all criteria consumers perceive Petrol Ofisi and Opet as brands which they never give preference to one another while other stations (Total, BP and Shell might be given preference to one another. However, Shell was perceived distinctively with only regards to its image/style and credit card offers.

    Two of the most daunting problems facing humankind in the twenty-first century are energy security and climate change. This report summarizes work accomplished towards addressing these problems through the execution of a Grand Challenge LDRD project (FY09-11). The vision of Sunshine to Petrol is captured in one deceptively simple chemical equation: Solar Energy + xCO{sub 2} + (x+1)H{sub 2}O {yields} C{sub x}H{sub 2x+2}(liquid fuel) + (1.5x+.5)O{sub 2} Practical implementation of this equation may seem far-fetched, since it effectively describes the use of solar energy to reverse combustion. However, it is also representative of the photosynthetic processes responsible for much of life on earth and, as such, summarizes the biomass approach to fuels production. It is our contention that an alternative approach, one that is not limited by efficiency of photosynthesis and more directly leads to a liquid fuel, is desirable. The development of a process that efficiently, cost effectively, and sustainably reenergizes thermodynamically spent feedstocks to create reactive fuel intermediates would be an unparalleled achievement and is the key challenge that must be surmounted to solve the intertwined problems of accelerating energy demand and climate change. We proposed that the direct thermochemical conversion of CO{sub 2} and H{sub 2}O to CO and H{sub 2}, which are the universal building blocks for synthetic fuels, serve as the basis for this revolutionary process. To realize this concept, we addressed complex chemical, materials science, and engineering problems associated with thermochemical heat engines and the crucial metal-oxide working-materials deployed therein. By project's end, we had demonstrated solar-driven conversion of CO{sub 2} to CO, a key energetic synthetic fuel intermediate, at 1.7% efficiency.

  13. Occupational Exposure of Diesel Station Workers to BTEX Compounds at a Bus Depot

    Raeesa Moolla

    2015-04-01

    Full Text Available Diesel fuel is known to emit pollutants that have a negative impact on environmental and human health. In developing countries like South Africa, attendants are employed to pump fuel for customers at service stations. Attendants refuel vehicles with various octane unleaded fuel, lead-replacement petrol and diesel fuel, on a daily basis. Attendants are at risk to adverse health effects associated with the inhalation of volatile organic compounds released from these fuels. The pollutants released include benzene, toluene, ethylbenzene and xylenes (BTEX, which are significant due to their high level of toxicity. In this study, a risk assessment of BTEX was conducted at a diesel service station for public buses. Using Radiello passive samplers, it was found that benzene concentrations were above recommended international standards. Due to poor ventilation and high exposure duration, the average benzene concentration over the sampling campaign exceeded the US Environmental Protection Agency’s chronic inhalation exposure reference concentration. Lifetime cancer risk estimation showed that on average there is a 3.78 × 10−4 cancer risk, corresponding to an average chronic daily intake of 1.38 × 10−3 mg/kg/day of benzene exposure. Additionally, there were incidences where individuals were at potential hazard risk of benzene and toluene that may pose non-carcinogenic effects to employees.

  15. Dermal lesions after post mortem petrol-exposure.

    Bux, R; Stengel, P D; Schnabel, A

    2006-11-10

    The effect of post mortem contact of the skin with petrol was investigated in 18 corpses with exposure times between 10 min and 24 h. The earliest onset of skin changes was observed within 2 h of exposure. They consisted of swelling and wrinkling with detachment of the upper layers of the skin (positive Nikolski's sign). Histologically the lesions appeared as non-vital acantholyses located in the prickle-cell layer with formation of intra-epidermal bullae. An influence of age and sex could be excluded, the earlier onset of lesions at 22 degrees C than at 4 degrees C was not statistically significant. These findings prove that post mortem petrol exposure may lead to dermal lesions.

    2014-06-01

    Full Text Available A comprehensive evaluation of the adverse health effects of human exposures to BTX from service station emissions was carried out using BTX exposure data from the scientific literature. The data was grouped into different scenarios based on activity, location and occupation and plotted as Cumulative Probability Distributions (CPD plots. Health risk was evaluated for each scenario using the Hazard Quotient (HQ at 50% (CEXP50 and 95% (CEXP95 exposure levels. HQ50 and HQ95 > 1 were obtained with benzene in the scenario for service station attendants and mechanics repairing petrol dispensing pumps indicating a possible health risk. The risk was minimized for service stations using vapour recovery systems which greatly reduced the benzene exposure levels. HQ50 and HQ95 < 1 were obtained for all other scenarios with benzene suggesting minimal risk for most of the exposed population. However, HQ50 and HQ95 < 1 was also found with toluene and xylene for all scenarios, suggesting minimal health risk. The lifetime excess Cancer Risk (CR and Overall Risk Probability for cancer on exposure to benzene was calculated for all Scenarios and this was higher amongst service station attendants than any other scenario.

    2010-06-01

    Full Text Available This paper examines the long-run and short-run determinants of unleaded petrol price in Australia’s capitalcities using monthly data to find out whether prices respond asymmetrically to external shocks. Based on thecointegration test results and the estimated asymmetric short-run dynamic models, it is found that: (1 in thelong-run petrol prices are mainly determined by Tapis crude oil and Singapore petrol prices; (2 there issome evidence of asymmetric price adjustments in the short-run since petrol price increases have been mostlypassed on to the consumer faster than price decreases in four capital cities. More specifically, this paperprovides convincing evidence in support of asymmetric price adjustments and the “rockets-and-feathershypothesis” in Adelaide, Brisbane, Melbourne and Sydney. One can thus argue that there are a significantdegree of market inefficiency and/or collusion, requiring a closer government price monitoring and scrutiny.

  1. LCAs of petrol and diesel - A literature review

    Eriksson, Mattias; Ahlgren, Serina

    2013-09-01

    Many life cycle assessment (LCA) studies have investigated the environmental impact of using biofuel in transportation compared with fossil fuels. Since these studies often use standard values for the fossil fuel reference scenario, there is a need for a thorough review of published data on fossil fuel use in transportation. This study reviewed the available literature regarding greenhouse gas (GHG) emissions and energy balances in petrol and diesel use and examined possible causes for the differences reported in the literature. This included differences connected to the LCA methodology itself, but also those resulting from technical and economic effects. Thirteen studies were reviewed in order to establish the level of GHG emissions and energy use in the well-to-tank perspective and, where possible, in the entire well-to-wheel perspective. The studies used different input data, allocation methods and system boundaries, but the results fell within a narrow range, since the energy content of the fuels on a tank-to-wheel basis differed only slightly, while the use phase represents most GHG emissions and energy usage in fuel life cycles. All studies reviewed reported GHG emissions values that exceeded the reference value of 83.8 g CO{sub 2}-eq/MJ fuel suggested in the EU Renewable Energy Directive.

  2. Research of combustion in older generation spark-ignition engines in the condition of use leaded and unleaded petrol

    2014-01-01

    Full Text Available This paper analyzes the potential problems in the exploitation of the older generation of spark-ignition engines with higher octane number of petrol (unleaded petrol BMB 95 than required (leaded petrol MB 86. Within the experimental tests on two different engines (STEYR-PUCH model 712 and GAZ 41 by applying piezoelectric pressure sensors integrated with the engine spark plugs, acceleration sensors (accelerometers and special electronic block connected with distributor, show that the cumulative first and second theoretical phase of combustion when petrol of higher octane number (BMB 95 is used lasts slightly longer than when the low-octane petrol MB 86 is used. For new petrol (BMB 95 higher optimal angles of pre-ignition have been determined by which better performances of the engine are achieved without a danger of the combustion with detonation (also called knocking.

  3. The ignitability of petrol vapours and potential for vapour phase explosion by use of TASER® law enforcement electronic control device.

    Clarke, C; Andrews, S P

    2014-12-01

    An experimental study was made of the potential of the TASER-X26™ law enforcement electronic control device to ignite petrol vapours if used by an officer to incapacitate a person soaked in petrol, or within a flammable atmosphere containing petrol vapour. Bench scale tests have shown that a wooden mannequin with pig skin covering the chest was a suitable representation of a human target. Full scale tests using the mannequin have shown that the arc from a TASER-X26™ is capable of igniting petrol/air vapours on a petrol-soaked person. Further tests in a 1/5 scale and a full scale compartment have shown that if a TASER is used within a compartment, a petrol vapour explosion (deflagration) may be achieved. It is evident from this research that if used in a flammable vapour rich environment, the device could prove fatal not only to the target but the TASER® operator as well.

  4. A comparison of exhaust emissions from vehicles fuelled with petrol, LPG and CNG

    Bielaczyc, P.; Szczotka, A.; Woodburn, J.

    2016-09-01

    This paper presents an analysis of THC, NMHC, CO, NOx and CO2 emissions during testing of two bi-fuel vehicles, fuelled with petrol and gaseous fuels, on a chassis dynamometer in the context of the Euro 6 emissions requirements. The analyses were performed on one Euro 5 bi-fuel vehicle (petrol/LPG) and one Euro 5 bi-fuel vehicle (petrol/CNG), both with SI engines equipped with MPI feeding systems operating in closed-loop control, typical three-way-catalysts and heated oxygen sensors. The vehicles had been adapted by their manufacturers for fuelling with LPG or CNG by using additional special equipment mounted onto the existing petrol fuelling system. The vehicles tested featured multipoint gas injection systems. The aim of this paper was an analysis of the impact of the gaseous fuels on the exhaust emission in comparison to the emission of the vehicles fuelled with petrol. The tests subject to the analyses presented here were performed in the Engine Research Department of BOSMAL Automotive Research and Development Institute Ltd in Bielsko-Biala, Poland, within a research programme investigating the influence of alternative fuels on exhaust emissions from light duty vehicle vehicles with spark-ignition and compression-ignition engines.

  5. A Temporal Association between Accumulated Petrol (Gasoline Lead Emissions and Motor Neuron Disease in Australia

    Mark A. S. Laidlaw

    2015-12-01

    Full Text Available Background: The age standardised death rate from motor neuron disease (MND has increased from 1.29 to 2.74 per 100,000, an increase of 112.4% between 1959 and 2013. It is clear that genetics could not have played a causal role in the increased rate of MND deaths over such a short time span. We postulate that environmental factors are responsible for this rate increase. We focus on lead additives in Australian petrol as a possible contributing environmental factor. Methods: The associations between historical petrol lead emissions and MND death trends in Australia between 1962 and 2013 were examined using linear regressions. Results: Regression results indicate best fit correlations between a 20 year lag of petrol lead emissions and age-standardised female death rate (R2 = 0.86, p = 4.88 × 10−23, male age standardised death rate (R2 = 0.86, p = 9.4 × 10−23 and percent all cause death attributed to MND (R2 = 0.98, p = 2.6 × 10−44. Conclusion: Legacy petrol lead emissions are associated with increased MND death trends in Australia. Further examination of the 20 year lag between exposure to petrol lead and the onset of MND is warranted.

  6. Plataformas para prospecciones petrolíferas en el mar

    Garnault, André

    1968-03-01

    Full Text Available The increasing consumption of petroleum makes it necessary to seek new producing areas, especially in the neighbourhood of the main consumption districts. The rock layers containing petroleum often extend beneath the sea, and in such cases the method of extraction of the petroleum involves specialised techniques, which depend on the nature of the site. The first tests were out in the Gulf of Mexico, where the sea is shallow and mainly calm. In Europe the problem is different, since the sea is usually deeper and more agitated, so that the classical drilling methods cannot be applied. To overcome these difficulties the floating platforms were introduced. These are taken to a given site, and fixed there. The French firm Neptune has two such platforms: «Neptune I» and «Neptune-Gascogne», whose functional features are described in this article. These platforms have three fixed points of support on the soil, but in the near future, to be able to reach depths of 200 to 300 m, it will be necessary to do without the fixed points of support, as they greatly limit the use of the platforms. Submergible platforms, with static or dynamic anchorage systems, are being studied, and it is hoped to carry out trials fairly soon.El aumento creciente en el consumo del petróleo obliga a buscar nuevas zonas productoras que amplíen la capacidad de reserva existente y que, por otra parte, se encuentren próximas a las principales zonas de consumo. Las capas sedimentarias que contienen los mantos petrolíferos se prolongan frecuentemente bajo el mar; en este medio su extracción presenta problemas muy diferentes según las características de la zona. Los primeros ensayos se realizaron en el Golfo de Méjico con profundidades pequeñas y mares calmados. En Europa el problema es distinto, puesto que generalmente se trata de mares profundos y muy agitados en los que no se puede utilizar normalmente los dispositivos clásicos de perforación. Para salvar esta limitaci

    Full Text Available This article describes a conceptual design for handling an oilfield’s industrial wastewater; its oblective was to use type-1 fractioned crystallisation within a feasible environmental and technical framework for obtaining the highest percentage of salt.La Gloria, La Gloria Norte and Morichal (all belonging to the Casanare department association stations were used for planning and analysing this handling alternative as they produce high salt-containing industrial effluent.This alternative was focused on treating 30% of the total volume of the associated water so produced. This volume is expected to be 1239 m3/d in 2000 in the oilfields being studied here. The process allows 92% retrieval from present NaCl (0.918 Ton/h, having 97% purity. Evaporation and aeration systems should be set prior to the crystallisation stage as a means of guaranteeing final product quality and making good use of the field’s facilities.

  11. Evaporative emissions of 1,3-butadiene from petrol-fuelled motor vehicles

    Ye, Y.; Galbally, I. E.; Weeks, I. A.; Duffy, B. L.; Nelson, P. F.

    This study reports the identification and quantification of 1,3-butadiene in petrol and in the evaporative emissions from Australian light-duty passenger vehicles. The mass fraction of 1,3-butadiene in each of the different grades of any brand of Australian petrol was found to be relatively constant for a given marketing area. However, the mass fractions vary significantly between the different brands (or refineries) from 0.004±0.001% to 0.047±0.008%. The measurements of the evaporative emissions of 1,3-butadiene from in-service motor vehicles were performed using standard Australian Design Rule 37/00 (ADR 37/00) Sealed Housing Evaporative Determination (SHED) tests. For post-1985 catalyst equipped vehicles fuelled with unleaded petrol, average evaporative emissions of 1,3-butadiene were 9.4 (0.7-22) and 5.0 (0.1-23) mg per test for diurnal and hot soak SHED tests, respectively. The corresponding average evaporative emissions for the older, pre-1986 non-catalyst equipped vehicles fuelled with leaded petrol were 26.5 (11.7-45.4) and 9.2 (4.3-13.1) mg per test, respectively, about double the observed emissions from newer vehicles. For the complete vehicle set (all ages), the average mass fraction of 1,3-butadiene in the total hydrocarbon (sum of C 1-C 10 hydrocarbons) emission was 0.21±0.14% from the diurnal phase and was 0.11±0.06% from the hot-soak phase. Evaporative emissions were estimated to contribute about 4% (ranging from 1-15%) of the total (exhaust and evaporative) emissions of 1,3-butadiene from Australian motor vehicles.

    Soil contaminated by hydrocarbons, cannot be used for agricultural intents due to their toxic effect to the plants. Surfactants producing by plant growth promotory rhizobacteria (PGPR) can effectively rig the problem of petroleum hydrocarbon contamination and growth promotion on such contaminated soils. In the present study three Pseudomonas strains isolated from contaminated soil identified by 16S rRNA analysis were ascertained for PGPR as well as biosurfactants property. Biosurfactants produced by the strains were further characterized and essayed for rhamnolipids. Inoculation of the strains in petrol hydrocarbon contaminated soil and its interaction with Withania somnifera in presence of petrol oil hydrocarbons depict that the strains helped in growth promotion of Withania somnifera in petrol oil contaminated soil while rhamnolipids helped in lowering the toxicity of petrol oil. The study was found to be beneficial as the growth and antioxidant activity of Withania sominfera was enhanced. Hence the present study signifies that rhamnolipids producing PGPR strains could be a better measure for reclamation of petrol contaminated sites for growing medicinal plants.

  14. Results of primary noise reduction measures on single cylinder two-stroke petrol engines

    Kuentscher, V.; Engler, G.; Eichlseder, H.

    1986-01-01

    EEC Regulations No 41/1/2 for two-wheeled vehicles and No 63/3 for mopeds, came into force in recent years as necessary contributions for improved environmental protection and for greater safety in traffic. The achievement of the long-term limits intended for the future will require considerable efforts from the motorcycle industry. As a contribution to this, extensive investigations were done on standard singlecylinder two-stroke petrol engines with a swept volume of 50 cc and of the same type, for which several variants were produced in order to meet the aim of less noise emission. This is a report on the results achieved.

    1995-12-31

    As the limits of the earth`s carrying capacity come to show, increasing pressure is brought to bear on private enterprise to behave in more environmentally responsible ways. One of the rare studies, that not only focuses on the enterprise level of analyse but at the industrial chain of production is Integrated Production Chain Management (IPCM), which postulates that the chain needs to be modified in its entirety. IPCM is not just a technical coordination problem but also a organizational problem in which different interests of actors play a role. These interests must be analysed. The present article will not go into the technical bottlenecks but will go into organizational bottlenecks that are the result of conflicts of interests. The choice between different technological options is not seen as a merely `technical` one but rather as a choice between different socio-technical (sub)systems. This choice is made in an interaction process in a network of various actors, each with their own perceptions and their own interests, in situations in which information is far from conclusive.

    The phase-out of leaded petrol has been a measure widely used to reduce atmospheric lead pollution. Since the 1980s, China began to promote unleaded petrol. In order to assess the effectiveness of the measure an isotope fingerprint technique was applied for aerosol samples in the city of Tianjin. After dilute acid leaching, the lead concentration and isotope abundance ratios were determined for 123 samples collected in Tianjin during eight years (1994-2001). The {sup 206}Pb / {sup 207}Pb ratio was lower in summer, when coal combustion emission was low and vehicle exhaust became more important, indicating that the {sup 206}Pb / {sup 207}Pb ratio of leaded petrol in Tianjin is lower than that of aerosol samples. The {sup 206}Pb / {sup 207}Pb ratio gradually increased from 1994 to 2001, a trend that suggests that the contribution from vehicle exhaust was diminishing. Overall, the measurements matched well with national statistical data of leaded and unleaded petrol production. After the nationwide switch to unleaded gasoline, comprehensive control measures are urgently needed to reduce air lead pollution in China, as aerosol lead reduced slightly but remains at a relatively high level.

  18. Emission of 1,3-butadiene from petrol-driven motor vehicles

    Ye, Y.; Galbally, I. E.; Weeks, I. A.

    This study reports the measurement of 1,3-butadiene emissions from 30 petrol-driven vehicles from the Australian car fleet using the Australian Design Rule 37/00 vehicle test procedure. Six of the cars tested were not equipped with catalytic converters and used leaded petrol as fuel. The remaining 24 cars were fitted with catalytic converters and used unleaded petrol. 1,3-Butadiene in exhaust samples was found to degrade rapidly in SUMMA treated stainless steel canisters and the degradation followed first-order kinetics. The rate coefficient of the decay can be represented by a linear dependence on the concentration of nitrogen oxides in the exhaust ( r2 = 0.79, n = 43), and the gas-phase reaction of NO 2 and 1,3-butadiene may have a major role in this loss. The 1,3-butadiene concentrations used to estimate vehicle emissions were corrected for this loss using the decay rate constant either observed from replicate analyses or from the NO x concentrations in the samples. The measurements showed that 1,3-butadiene was emitted at a rate of 20.7 ± 9.2 mg km -1 from 6 non-catalyst vehicles. There was considerable scatter in the observations from catalyst equipped vehicles and we infer that this was due to the malfunction of the emission control devices on some vehicles. The 19 vehicles that appeared to have functioning catalyst emission control devices had an average emission rate of 2.1 ± 1.5 mg km -1. These emission rates are consistent with atmospheric observations and are much higher than those reported previously. We calculate that more than 90% of the 1,3-butadiene in engine exhaust comes from the common alkane and aromatic constituents of the fuel. A comparison of emissions in the different phases of the drive cycle indicates that current emission controls remove more than 90% of the 1,3-butadiene from the initial exhaust mixture.

    Full Text Available Long term exposure to solvents and air pollutants can lead to deleterious effects on respiratory, haematological and thyroid functioning. The aim of this study was to investigate whether chronic exposure to solvents like benzene and pollutants like carbon monoxide in petrol filling workers had adverse effect on blood parameters, thyroid and respiratory functions. The study group consisted of 42 healthy, non-smoker petrol filling workers, aged 20-50 years with work (exposure duration from 2-15 years while 36 healthy subjects of the same age group served as controls. Physical examination and measurement of pulmonary functions by portable electronic spirometer were performed. Complete blood pictures (CBP were determined by normal haematology lab procedure and hormones by Chemiluminescence immunoassay (CLIA light absorption techniques. There was a significant decrease in the lung volumes and capacities; the restrictive pattern was more prevalent in the workers when compared with the control groups. But in the workers exposed for long period (more than 10 years the restrictive pattern was changed to mixed pattern. A significant increase in haemoglobin (Hb (>16 mg % and red blood cells (RBC (5.4 million cells/mm3 were observed in workers with longer period of exposure when compared with the control subjects (14.483 mg% and 4.83 million cells/mm3 for Hb and RBC respectively. White blood cell count except eosinophils and platelets were significantly lower in workers compared to controls. Marked increase in the tetra iodothyroinine (T4, free thyroxine (T4F level and significant decrease in thyroid stimulating hormones (TSH, and tri-iodothyronine (T3 were observed between long term exposed and non – exposed groups. Till now researchers focused only on the effect of solvents in workers professionally exposed to solvents without considering the effect of concomittant air pollution. The result obtained from present study indicates that there is

  2. Condition monitoring of valve clearance fault on a small four strokes petrol engine using vibration signals

    Songpon Klinchaeam

    2010-12-01

    Full Text Available This paper studies condition monitoring technique of a small four strokes, single cylinder petrol engine using vibrationsignal analysis based on time domain, crank angle domain, and signal energy. Vibration signals are acquired from the cylinderhead of the engine and used to describe engine processes such as intake/exhaust valve operations, ignition process, andcombustion process. In this study, vibration signals have been applied to monitor various fault conditions in the engine suchas intake and exhaust valve clearance faults. Vibration signals acquired in time domain could be mapped onto crank angledomain using top dead center signal. Time domain techniques were used to analyze vibration signals so that the main eventsrelated to the engine operations could be described easily. Using energy analysis technique, all fault conditions could bealso identified. For future work, signal analysis techniques must be developed and the detected signals should be comparedwith other signals such as pressure signal in order to verify the accuracy of the results.

    Full Text Available In the present work, an experimental investigation is carried out to evaluate the use of plastic oil derived from waste plastic which used in a Spark Ignition engine. Experiments are conducted, the measured performance and emissions of plastic oil blends at different proportions are compared with the baseline operation of the SI engine running with gasoline fuel. Engine performance and exhaust gas emissions such as carbon monoxide, total unburned hydrocarbons, carbon dioxide and oxides of nitrogen are measured. From the experiments it is observed that 50% Distilled Plastic Pyrolysis Oil (50%DPPO exhibits the substantial enhancement in brake power, brake thermal efficiency and reduction in brake specific fuel consumption running at full load conditions among different blends and pure petrol. There is also noticed decrement of carbon dioxide and unburned hydrocarbons emissions at the same blend. The experimental result shows that plastic oil shall conveniently be used as a substitute to gasoline in the existing SI engines without any modifications.

  7. Role of compost, bentonite and calcium oxide in restricting the effect of soil contamination with petrol and diesel oil on plants.

    Wyszkowski, Mirosław; Ziólkowska, Agnieszka

    2009-02-01

    The studies have been initiated to find a way to use compost, bentonite and calcium oxide in order to reduce the effect of contaminated soil with a small amount of petrol or diesel oil on the yield and nitrogen content in crop plants--spring rape and oats cultivated as the main and aftercrop. Petrol and diesel oil had a toxic effect on the growth of the plants and modified nitrogen content, with the intensity of the effect depending upon their type and dose and on the type of applied substance reducing the effect of oil derivatives. Spring rape (main crop), was more sensitive, and oats (aftercrop) was less so. Petroleum-derived substances reduced the yield of spring rape by a maximum of 73% for petrol and by as much as 99% for diesel oil. Nitrogen content was higher for spring rape than for oats and larger for petrol than for diesel oil. Adding bentonite, calcium oxide or compost to the soil contaminated with oil derivatives usually reduced the negative effect of petrol and diesel oil on plant growth and reduced the protein nitrogen content and increased the total nitrogen content in plants. Bentonite proved to be the most effective, with calcium oxide and compost slightly less so. The most positive results were obtained for spring rape as the main crop. An addition of compost, bentonite and calcium oxide to soil had a stronger modifying effect on nitrogen content in plants on soils contaminated by diesel oil than petrol.

  9. Environmental Analysis of Petrol, Diesel and Electric Passenger Cars in a Belgian Urban Setting

    Nils Hooftman

    2016-01-01

    Full Text Available The combustion of fossil fuels in the transport sector leads to an aggravation of the air quality along city roads and highways. Urban air quality is a serious problem nowadays as the number of vehicles increases on a yearly basis. With stricter Euro emission regulations, vehicle manufacturers are not meeting the imposed limits and are also disregarding the non-exhaust emissions. This paper highlights the relevance of non-exhaust emissions of passenger vehicles, both conventional (diesel and petrol or electric vehicles (EV, on air quality levels in an urban environment in Belgium. An environmental life cycle assessment was carried out based on a real-world emission model for passenger cars and fuel refinery data. A cut-off was applied to the models to highlight what emissions, both from the refinery to the exhaust and electricity production for EV, do actually occur within Belgium’s borders. Results show that not much progress has been made from Euro 4 to 6 for conventional vehicles. Electric vehicles pose the best alternative solution as a more environmentally friendly means of transportation. The analysis results target policy makers with the intention that regulations and policies would be developed in the future and target the characterization of non-exhaust emissions from vehicles. These results indicate that EVs offer a valid solution for addressing the urban air quality issue and that non-exhaust emissions should be addressed in future regulatory steps as they dominate the impact spectrum.

  10. TOPSIS Multi-Criteria Decision Modeling Approach for Biolubricant Selection for Two-Stroke Petrol Engines

    2015-12-01

    Full Text Available Exhaust pollutants from two-stroke petrol engines are a problem for the environment. Biolubricants are a new generation of renewable and eco-friendly vegetable-based lubricants, which have attracted a lot of attention in recent years. In this paper, the applicability of the Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS method to support the process of building the scoring system for selecting an appropriate two-stroke lubricant has been analyzed. For this purpose, biolubricants (TMP-triesters based on castor oil, palm oil, and waste cooking oil were produced and then utilized in a 200 cc two-stroke gasoline engine to investigate their effects on its performance and exhaust emissions. The results obtained from the use of the entropy technique in the TOPSIS algorithm showed that palm oil-based lubricant took up the greatest distance from the Negative Ideal Solution (NIS and was selected as the most optimal lubricant for these types of engines.

  11. Particle and carbon dioxide emissions from passenger vehicles operating on unleaded petrol and LPG fuel.

    Ristovski, Z D; Jayaratne, E R; Morawska, L; Ayoko, G A; Lim, M

    2005-06-01

    A comprehensive study of the particle and carbon dioxide emissions from a fleet of six dedicated liquefied petroleum gas (LPG) powered and five unleaded petrol (ULP) powered new Ford Falcon Forte passenger vehicles was carried out on a chassis dynamometer at four different vehicle speeds--0 (idle), 40, 60, 80 and 100 km h(-1). Emission factors and their relative values between the two fuel types together with a statistical significance for any difference were estimated for each parameter. In general, LPG was found to be a 'cleaner' fuel, although in most cases, the differences were not statistically significant owing to the large variations between emissions from different vehicles. The particle number emission factors ranged from 10(11) to 10(13) km(-1) and was over 70% less with LPG compared to ULP. Corresponding differences in particle mass emission factor between the two fuels were small and ranged from the order of 10 microg km(-1) at 40 to about 1000 microg km(-1) at 100 km h(-1). The count median particle diameter (CMD) ranged from 20 to 35 nm and was larger with LPG than with ULP in all modes except the idle mode. Carbon dioxide emission factors ranged from about 300 to 400 g km(-1) at 40 km h(-1), falling with increasing speed to about 200 g km(-1) at 100 km h(-1). At all speeds, the values were 10% to 18% greater with ULP than with LPG.

  14. Station Capacity

    Landex, Alex

    2011-01-01

    Stations are often limiting the capacity of railway networks. This is due to extra need of tracks when trains stand still, trains turning around, and conflicting train routes. Although stations are often the capacity bottlenecks, most capacity analysis methods focus on open line capacity. Therefore......, this paper presents methods to analyze station capacity. Four methods to analyze station capacity are developed. The first method is an adapted UIC 406 capacity method that can be used to analyze switch zones and platform tracks at stations that are not too complex. The second method examines the need...... for platform tracks and the probability that arriving trains will not get a platform track immediately at arrival. The third method is a scalable method that analyzes the conflicts in the switch zone(s). In its simplest stage, the method just analyzes the track layout while the more advanced stages also take...

  15. Using Attendance Worksheets to Improve Student Attendance, Participation, and Learning

    Rhoads, Edward

    2013-06-01

    As science instructors we are faced with two main barriers with respect to student learning. The first is motivating our students to attend class and the second is to make them active participants in the learning process once we have gotten them to class. As we head further into the internet age this problem only gets exacerbated as students have replaced newspapers with cell phones which can surf the web, check their emails, and play games. Quizzes can motivated the students to attend class but do not necessarily motivate them to pay attention. Active learning techniques work but we as instructors have been bombarded by the active learning message to the point that we either do it already or refuse to. I present another option which in my classroom has doubled the rate at which students learn my material. By using attendance worksheets instead of end of class quizzes I hold students accountable for not just their attendance but for when they show up and when they leave the class. In addition it makes the students an active participant in the class even without using active learning techniques as they are writing notes and answering the questions you have posed while the class is in progress. Therefore using attendance worksheets is an effective tool to use in order to guide student learning.

  18. Severe petrol contamination in the aquifer of the Llobregat river delta. Grave contaminacion por gasolina en el acuifero del delta del rio Llobregat

    Garcia Gonzalez, E.

    1993-07-01

    On 16-09-91 an attack on an oil pipeline led to some 70 tons of petrol spilling out and catching fire. About 20 tons filtered down into the aquifer of the river Llobregat delta. On 08-12-91 the presence of petrol was detected in a well used for supplying water about 1 km downstream. A system was set up for monitoring and extracting the polluted ground water. The volume affected had now reached 3.5 hm''3. The decontamination costs came to 245 million pesetas in comparison to only 10 millions pesetas for the petrol spill. The cost of extracting the water was 70 pta/m''3. Finally the importance of regional planning and the need to prevent such accidents is pointed out. The means necessary to deal with them should be available. (Author)

  19. On exhaust emissions from petrol-fuelled passenger cars at low ambient temperatures

    Laurikko, J. [VTT Energy, Espoo (Finland). Energy Use

    1998-11-01

    The study at hand deals with regulated and unregulated exhaust emissions from petrol-fuelled cars at low ambient temperatures with present-day or near-future exhaust after treatment systems. The subject has been investigated at VTT over a decade and this report compiles data from various sub-studies carried out between the years 1993 - 1997. Each one of them viewed different aspects of the phenomenon, like determining the low-temperature response of today`s new cars employing three-way catalytic converters or assessing the long-term durability and the influence of vehicle mileage upon the low-temperature emissions performance. Within these studies, together more than 120 cars of model years from 1990 to 1997 have been tested. Most of them were normal, in-service vehicles with total mileages differing between only a few thousand kilometres for new cars up to 80,000 km or even more for the in-use vehicles. Both the US FTP75 and the European test cycle have been employed, and the ambient temperatures ranged from the baseline (+22 deg C) down to +- O deg C, -7 deg C and in some cases even to -20 deg C. The studies attested that new cars having today`s advanced emissions control systems produced fairly low levels of emissions when tested in conditions designated in the regulations that are the basis of the current new-vehicle certification. However, this performance was not necessarily attained at ambient temperatures that were below the normative range. Fairly widespread response was recorded, and cars having almost equal emissions output at baseline could produce largely deviating outcomes in low-temperature conditions. On average, CO and HC emissions increased by a factor of five to 10, depending on the ambient temperature and vehicle type. However, emissions of NO{sub x} were largely unaffected. Apart from these regulated emissions, many unregulated species were also determined, either by using traditional sampling and chromatography methods or on-line, employing

    Hydrogen is an environmentally attractive transportation fuel that has the potential to displace fossil fuels. The Freedom CAR and Freedom FUEL initiatives emphasize the importance of hydrogen as a future transportation fuel. Presently, Las Vegas has one hydrogen fueling station powered by natural gas. However, the use of traditional sources of energy to produce hydrogen does not maximize the benefit. The hydrogen fueling station developed under this grant used electrolysis units and solar energy to produce hydrogen fuel. Water and electricity are furnished to the unit and the output is hydrogen and oxygen. Three vehicles were converted to utilize the hydrogen produced at the station. The vehicles were all equipped with different types of technologies. The vehicles were used in the day-to-day operation of the Las Vegas Valley Water District and monitoring was performed on efficiency, reliability and maintenance requirements. The research and demonstration utilized for the reconfiguration of these vehicles could lead to new technologies in vehicle development that could make hydrogen-fueled vehicles more cost effective, economical, efficient and more widely used. In order to advance the development of a hydrogen future in Southern Nevada, project partners recognized a need to bring various entities involved in hydrogen development and deployment together as a means of sharing knowledge and eliminating duplication of efforts. A road-mapping session was held in Las Vegas in June 2006. The Nevada State Energy Office, representatives from DOE, DOE contractors and LANL, NETL, NREL were present. Leadership from the National hydrogen Association Board of Directors also attended. As a result of this session, a roadmap for hydrogen development was created.

  2. Analysis of the polycyclic aromatic hydrocarbon content of petrol and diesel engine lubricating oils and determination of DNA adducts in topically treated mice by 32P-postlabelling.

    Carmichael, P L; Jacob, J; Grimmer, G; Phillips, D H

    1990-11-01

    Engine lubricating oils are known to accumulate carcinogenic polycyclic aromatic hydrocarbons (PAHs) during engine running. Oils from nine petrol-powered and 11 diesel-powered vehicles, in addition to samples of unused oil, were analysed for PAH content and ability to form DNA adducts when applied topically to mouse skin. The levels of 19 PAHs, determined by GC, were in total, approximately 22 times higher in used oils from petrol engines than in oils from diesel engines. Male Parkes mice were treated with 50 microliters of oil daily for 4 days before they were killed and DNA isolated from skin and lung tissue. DNA samples were analysed by nuclease P1-enhanced 32P-postlabelling. Used oils from both diesel and petrol engines showed several adduct spots on PEI-cellulose plates at total adduct levels of up to 0.57 fmol/microgram DNA [approximately 60 times greater than in experiments with samples of unused oil in which adduct levels (0.01-0.02 fmol adducts/microgram DNA) were close to the limit of detection]. Higher adduct levels were generally formed by petrol engine oils than by diesel engine oils. Lung DNA contained similar total adduct levels to those in skin although the adduct maps were less complex. Total adduct levels correlated with extent of oil use in the engine, the total PAH concentration in oils and with the concentrations of certain individual PAHs present in the oils. An adduct spot that co-eluted with that of the major benzo[a]pyrene-DNA adduct accounted for 9-26% of the total adducts in skin DNA, and approximately 8% of the adducts in lung DNA, of mice treated with petrol engine oils. A major, and as yet unidentified, adduct spot comprised up to 30% of the total adducts in skin DNA, and up to 89% of the total adducts in lung DNA, of these animals.

  3. A house with its own filling station; Das Haus mit der eigenen Tankstelle

    Stadelmann, M.

    2005-07-01

    This short article describes how a house in Erlinsbach, Switzerland was rebuilt and, at the same time, fitted with a new gas-fired heating system - and with its own natural gas filling station. The history behind this unusual project is discussed. The inclusion of a filling station in the project made it worthwhile for the gas utility to lay a connection from the gas mains to the house. The economic advantages for its builder, who sells such natural gas filling station equipment, are mentioned. The consumption of the natural gas used as motor fuel is measured and taxed separately. Equivalent fuel costs are now said by the owner to be already below today's petrol prices and will become even lower when the planned reduction of levies on such use of natural gas come into force.

    Lech, M M; Mngadi, T P

    2005-12-01

    The Traditional Birth Attendants (TBAs) Survey in Swaziland was undertaken between March 27th 1996 and April 8th 1996. The objective of the survey was to generate reliable information regarding activities of TBAs in Swaziland. The survey was conducted in 25 Chiefdoms sampled out of a total of 206 Chiefdoms registered in Swaziland. The total number of sampled respondents in the 25 Chiefdoms was 721. From the survey, it is estimated that there were probably 3000 TBAs in the country, and in the majority of cases such TBAs would be a 51-year old woman who herself had delivered six children and had worked as a TBA for at least 10 years. Between 9,000 and 12,000 deliveries are estimated to take place out of health facilities. Of these many, nearly 43.5% are assisted by "TBAs"; 16.3% of woman interviewed deliver relative/family member and 15.1% are assisted by friends/neighbours, etc. Some of TBAs carry out procedures which are considered to be potentially harmful. Nearly 30% of TBAs have administered herbs; 45% attend to abnormal deliveries (breech and multiple pregnancies); 26.7% re-use their cord cutting tools and in the case of haemorrhage 23.4% do manual procedures within reproductive tract of delivering women.

    1994-05-01

    Full Text Available Traditional Birth Attendants (TBAs and traditional healers form an important link in the chain of health personnel providing primary health care in Malawi. In spite of the establishment of hospitals and health centres, it is to these traditional healers and TBAs that the majority of people turn in times of sickness and child-birth. Approximately 60 percent of all deliveries in Malawi occur in the villages. It is therefore important that due regard be paid to the activities of these traditional practitioners in order to ensure the achievement of the goal - "Health for all by the year 2000". The training of TBAs is seen as part of the Maternal and Child Health Services in the country.

  8. 32P-postlabelling analysis of DNA adducts in the skin of mice treated with petrol and diesel engine lubricating oils and exhaust condensates.

    Schoket, B; Hewer, A; Grover, P L; Phillips, D H

    1989-08-01

    Samples of unused or used petrol and diesel engine lubricating oils were applied to the shaved dorsal skin of 4- to 6-week-old male Parkes mice, either as a single treatment (50 microliters/mouse) or as four consecutive daily treatments (50 microliters/application). DNA isolated from the skin 24 h after the final treatment was digested to 3'-mononucleotides and analysed by 32P-postlabelling for the presence of aromatic adducts. Enhancement of sensitivity using butanol extraction or nuclease P1 digestion of the DNA hydrolysates led to the detection of up to eight adduct spots on polyethyleneimine-cellulose thin-layer chromatograms with samples of DNA from skin treated with used engine oils, at levels of 40-150 amol total adducts/micrograms DNA. Multiple treatments with the used oils gave rise to similar patterns of adducts in lung DNA. A single treatment of mouse skin with petrol engine exhaust condensate (50 microliters), or diesel engine exhaust condensate (50 microliters), containing 20 and 46 micrograms benzo[a]pyrene (BaP)/g respectively, gave rise to approximately 75 amol total adducts/micrograms DNA in skin. A significant proportion, 31 and 48% respectively, of the adducts formed by the petrol and diesel engine exhaust condensates co-chromatographed with the major BaP-DNA adduct, but with the used engine oils, only petrol engine oil, and not diesel engine oil, produced significant amounts of an adduct (22% of total) that corresponded to the BaP-DNA adduct.

  9. An in vitro Assessment on the Efficacy of Clay-Based Formulated Cells of Pseudomonas Isolate UTAR EPA2 for Petrol Degradation

    A. S.Y. Ting

    2010-01-01

    Full Text Available Problem statement: Application of free-cell forms is usually impractical to achieve satisfactory bioremediative effect because the microbes are encumbered by the biotic and abiotic stresses from the environment. Approach: In this study, a hydrocarbon-degrading bacterium (Pseudomonas isolate UTAR EPA2 was formulated with various combinations of formulative materials, comprising of clay-based carrier materials such as Bentonite (B and Kaolin (K, enrichment materials such as Non-fat skimmed milk (N and Sucrose (S and a UV-protectant agent Para-aminobenzoic acid (P. Formulated cells were treated to sunlight exposure for 6 h to mimic the conditions in the environment prior to testing for their efficacy in degrading petrol, a mixed hydrocarbon substrate. Results: Cells in all formulations including free-cell suspension were able to degrade petrol with a relatively high degradation efficacy of more than 66% even after exposure to sunlight. Degradation efficacy was slightly higher for kaolin-based formulated cells compared to bentonite-based formulations, especially after exposure to sunlight, although their percentages of degradation were not statistically different. Nevertheless, kaolin-based formulations have very low viable cell count especially in formulations with P (KP, KNP, KSP, KNSP. This suggested that aside from viable cells, the physical properties of the clays could have also contributed to the degradation of petrol. Conclusion: For storage purposes and applications in the field, we suggest that the bacterium is formulated with bentonite-based formulations especially using Bentonite (B clay singly, as relatively high percentage of petrol degradation and viable cell count was achieved with this formulation.

  10. DNA adducts in human and mouse skin maintained in short-term culture and treated with petrol and diesel engine lubricating oils.

    Carmichael, P L; Ni Shé, M; Phillips, D H

    1991-05-24

    Human and mouse skin samples maintained in short-term organ culture were treated topically with used engine oils from petrol- and diesel-powered vehicles. Mice were also treated topically in vivo for comparison. DNA was isolated and analysed by 32P-postlabelling and the labeled DNA digests were resolved on polyethyleneimine-cellulose tlc sheets. A large number of radioactive adduct spots were observed in DNA from skin treated with the used petrol-engine oil, indicating the formation of adducts by many components of the complex oil mixture. Total adduct levels were similar in mouse skin (both in vivo and in vitro) and in human skin, although qualitative differences in the adduct maps were apparent between the human and mouse skin DNA. Treatment with the used diesel engine oil produced adduct levels no greater than that of control samples in mouse skin (in vivo and in vitro), although significant levels were found in human skin DNA from one donor. The results correlate well with the carcinogenic activity of these oils in experimental animals, helping to substantiate the conclusion that petrol engine oils (but not diesel engine oils) may present a carcinogenic risk to man if appropriate measures to minimise skin contact are not observed.

  11. Characterization of on-road CO, HC and NO emissions for petrol vehicle fleet in China city

    2006-01-01

    Vehicle emissions are a major source of air pollution in urban areas. The impact on urban air quality could be reduced if the trends of vehicle emissions are well understood. In the present study, the real-world emissions of vehicles were measured using a remote sensing system at five sites in Hangzhou, China from February 2004 to August 2005. More than 48000 valid gasoline powered vehicle emissions of carbon monoxide (CO), hydrocarbons (HC) and nitrogen oxide (NO) were measured. The results show that petrol vehicle fleet in Nangzhou has considerably high CO emissions, with the average emission concentration of 2.71%±0.02% , while HC and NO emissions are relatively lower, with the average emission concentration of (153.72± 1.16)× 10-6 and (233.53±1.80)× 10-6, respectively. Quintile analysis of both average emission concentration and total amount emissions by model year suggests that in-use emission differences between well maintained and badly maintained vehicles are larger than the age-dependent deterioration of emissions. In addition, relatively new high polluting vehicles are the greatest contributors to fleet emissions with, for example, 46.55% of carbon monoxide fleet emissions being produced by the top quintile high emitting vehicles from model years 2000~2004. Therefore, fleet emissions could be significantly reduced if new highly polluting vehicles were subject to effective emissions testing followed by appropriate remedial action.

  15. A Study on Attendance and Academic Achievement

    Sund, Kristian J.; Bignoux, Stephane

    In this study we attempt to answer Romer’s (1993) question: “Should attendance be mandatory?” Contrary to many existing studies, we conclude that in the case of business and management programs the answer is ‘no’. In a study of over 900 undergraduate strategy students, spanning four academic years......, we examine the link between attendance and exam results. Unlike prior research on this topic, our findings show that attendance is not the best determinant of student performance. We find instead that the best determinant of student performance for third year bachelor students is their over......-all degree classification, which we see as a proxy for academic ability. We suggest that attendance may simply be a reflection of student conscientiousness, engagement and motivation. We also challenge the assumptions about gender differences found in prior research on student attendance and student...

  1. Epidemiology of frequent attenders: a 3-year historic cohort study comparing attendance, morbidity and prescriptions of one-year and persistent frequent attenders

    ter Riet Gerben

    2009-01-01

    Full Text Available Abstract Background General Practitioners spend a disproportionate amount of time on frequent attenders. So far, trials on the effect of interventions on frequent attenders have shown negative results. However, these trials were conducted in short-term frequent attenders. It would be more reasonable to target intervention at persistent frequent attenders. Typical characteristics of persistent frequent attenders, as opposed to 1-year frequent attenders and non-frequent attenders, may generate hypotheses regarding modifiable factors on which new randomized trials may be designed. Methods We used the data of all 28,860 adult patients from 5 primary healthcare centers. Frequent attenders were patients whose attendance rate ranked in the (age and sex adjusted top 10 percent during 1 year (1-year frequent attenders or 3 years (persistent frequent attenders. All other patients on the register over the 3-year period were referred to as non-frequent attenders. The lists of medical problems coded by the GP using the International Classification of Primary Care (ICPC were used to assess morbidity. First, we determined which proportion of 1-year frequent attenders was still a frequent attender during the next two consecutive years and calculated the GPs' workload for these patients. Second, we compared morbidity and number of prescriptions for non-frequent attenders, 1-year frequent attenders and persistent frequent attenders. Results Of all 1-year frequent attenders, 15.4% became a persistent frequent attender equal to 1.6% of all patients. The 1-year frequent attenders (3,045; 10.6% were responsible for 39% of the face-to-face consultations; the 470 patients who would become persistent frequent attenders (1.6% were responsible for 8% of all consultations in 2003. Persistent frequent attenders presented more social problems, more psychiatric problems and medically unexplained physical symptoms, but also more chronic somatic diseases (especially diabetes

    1984-04-01

    Full Text Available From the petrogenetic study is established that pluton of Trujillo is an porphyritic adamellite, crystallised in three phases with an alteration one. Later, the porphyritic microadamellite crystallised in three petrogenetic facies: biotitic, leucocratic and turmaline. Each facies has three crystalitation phases and an alteration one. The major elements were analysed in adamellites, microadamellites and contacts between tugsten veins and porphyritic adamellite. From Harker, AFM and CaO-Na2O-K2O diagrams is emphasized an alcaline and peraluminic character. The distribution of trace elements is agree with the material evolution; Rb, Cs. Sr. Ba y Li settle better this connection.

    En función del estudio petrológico, el plutón de Trujillo está constituido por una adamellita porfídica que ha cristalizado en tres fases, presentando una cuarta de alteración. Posteriormente consolidó la microadamellita porfídica, bajo tres facies petrogenéticas, en el siguiente orden: Biotítica, leucocrática y turmalinizada. Cada una de estas tres facies comportan tres fases de cristalización y una de alteración. El análisis de elementos mayores ha sido realizado en las adamellitas, microadamellitas y en los contactos de: los filones volframíferos con la adamellita porfídica. De la interpretación del los diagramas de Harker y de los triangulares AFM y CaO-Na2-K2O se deduce un marcado carácter alcalino y peraluminoso en los tres grupos de muestras. Se han analizado también numerosos elementos traza, observándose una cIara concordancia entre el grado de diferenciación del material y el contenido en dichos elementos; siendo Rb, Cs, Sr, Ba y Li los que mejor reflejan dicha evolución.

  3. Religious Affiliation, Religious Service Attendance, and Mortality.

    Kim, Jibum; Smith, Tom W; Kang, Jeong-han

    2015-12-01

    Very few studies have examined the effects of both religious affiliation and religiosity on mortality at the same time, and studies employing multiple dimensions of religiosity other than religious attendance are rare. Using the newly created General Social Survey-National Death Index data, our report contributes to the religion and mortality literature by examining religious affiliation and religiosity at the same time. Compared to Mainline Protestants, Catholics, Jews, and other religious groups have lower risk of death, but Black Protestants, Evangelical Protestants, and even those with no religious affiliation are not different from Mainline Protestants. While our study is consistent with previous findings that religious attendance leads to a reduction in mortality, we did not find other religious measures, such as strength of religious affiliation, frequency of praying, belief in an afterlife, and belief in God to be associated with mortality. We also find interaction effects between religious affiliation and attendance. The lowest mortality of Jews and other religious groups is more apparent for those with lower religious attendance. Thus, our result may emphasize the need for other research to focus on the effects of religious group and religious attendance on mortality at the same time.

    Scantlebury, Rachel; Rowlands, Gillian; Durbaba, Stevo;

    2015-01-01

    BACKGROUND: Demand for England's accident and emergency (A&E) services is increasing and is particularly concentrated in areas of high deprivation. The extent to which primary care services, relative to population characteristics, can impact on A&E is not fully understood. AIM: To conduct...... a detailed analysis to identify population and primary care characteristics associated with A&E attendance rates, particularly those that may be amenable to change by primary care services. DESIGN AND SETTING: This study used a cross-sectional population-based design. The setting was general practices.......1, B = 547.3 [95% CI = 418.6 to 676.0]). The final model explained 34.4% of the variation in A&E attendance rates, mostly due to factors that could not be modified by primary care services. CONCLUSION: Demographic characteristics were the strongest predictors of A&E attendance rates. Primary care...

  19. Space station, 1959 to . .

    Butler, G. V.

    1981-04-01

    Early space station designs are considered, taking into account Herman Oberth's first space station, the London Daily Mail Study, the first major space station design developed during the moon mission, and the Manned Orbiting Laboratory Program of DOD. Attention is given to Skylab, new space station studies, the Shuttle and Spacelab, communication satellites, solar power satellites, a 30 meter diameter radiometer for geological measurements and agricultural assessments, the mining of the moons, and questions of international cooperation. It is thought to be very probable that there will be very large space stations at some time in the future. However, for the more immediate future a step-by-step development that will start with Spacelab stations of 3-4 men is envisaged.

  5. A Students Attendance System Using QR Code

    Fadi Masalha

    2014-01-01

    Full Text Available Smartphones are becoming more preferred companions to users than desktops or notebooks. Knowing that smartphones are most popular with users at the age around 26, using smartphones to speed up the process of taking attendance by university instructors would save lecturing time and hence enhance the educational process. This paper proposes a system that is based on a QR code, which is being displayed for students during or at the beginning of each lecture. The students will need to scan the code in order to confirm their attendance. The paper explains the high level implementation details of the proposed system. It also discusses how the system verifies student identity to eliminate false registrations.

  6. Non-attendance at a difficult-asthma clinic.

    McDonough, Beverley; Mault, Susan

    Increasing demand for our weekly difficult-asthma clinic means routine appointments are at a premium. This led us to explore the reasons why patients failed to attend for appointments and whether contacting them by telephone within a week of their missed scheduled appointment increased attendance. Memory lapses were the most common reason for non-attendance. Telephoning non-attenders led to a two-fold increase in attendance at subsequent clinics. Non-attendance may be a reflection of poor concordance, which, in itself, may contribute to a patient's difficult asthma.

    Landex, Alex

    2011-01-01

    special focus when conducting UIC 406 capacity analyses.This paper describes how the UIC 406 capacity method can be expounded for stations. Commonly for the analyses of the stations it is recommended to include the entire station including the switch zone(s) and all station tracks. By including the switch...... zone(s) the possible conflicts with other trains (also in the opposite direction) are taken into account leading to more trustworthy results. Although the UIC 406 methodology proposes that the railway network should be divided into line sections when trains turn around and when the train order...... is changed, this paper recommends that the railway lines are not always be divided. In case trains turn around on open (single track) line, the capacity consumption may be too low if a railway line is divided. The same can be the case if only few trains are overtaken at an overtaking station. For dead end...

  2. Minor injury attendance times to the ED.

    Conlon, Ciaran

    2009-07-01

    The Health Service Executive (HSE) highlights the need for effective patient throughput and management, whilst providing appropriate staffing and therapeutic interventions. It acknowledges that patient need is integral to the development of a nurse led service and advocates planning staffing levels to reflect arrival times of patients. An observational study of all patients who presented to the emergency department in July 2005 and February 2006 was undertaken (n=7768). The study identified 1577 patients suitable for treatment by the Advanced Nurse Practitioner (ANP) in these two months, which represents 20% of all patient attendances to the ED in this time period. A data collection tool was devised collectively by the ANPs to identify appropriate patients. The findings of the study revealed that 73% of patients suitable for the ANP service presented between the hours of 0800 and 2000, of which 54% attended between 0800 and 1600 h. Sunday emerged as the busiest day in July 2005 whereas Monday was found to be the busiest day in February 2006. Friday was found to be consistently busy for both months.

    Full Text Available Abstract Today students class attendance is become more important part for any organizationsinstitutions. The conventional method of taking attendance by calling names or signing on paper is very time consuming and insecure hence inefficient. This paper presents the manual students attendance management into computerized system for convenience or data reliability. So the system is developed by the integration of ubiquitous computing systems into classroom for managing the students attendance using RFID and fingerprint reader. The system is designed to implement an attendance management system based on RFID and fingerprint reader which students need to use their student identification card ID and their finger ID to success the attendance where only authentic student can be recorded the attendance during the class. In this system passive RFID tag and reader pairs are used to register the student ID cards individually and fingerprint reader is used for attendance. This system takes attendance electronically with the help of the RFID and finger print device and the records of the attendance are stored in a database. Students roll call percentages and their details are easily seenvia Graphical User Interface GUI. This system will have the required databases for students attendance teachers subjects and students details. This application is implemented by Microsoft Visual Studio and Microsoft SQL Server as IDE. C language is used to implement this system.

  5. The Princess Elisabeth Station

    Berte, Johan

    2012-01-01

    Aware of the increasing impact of human activities on the Earth system, Belgian Science Policy Office (Belspo) launched in 1997 a research programme in support of a sustainable development policy. This umbrella programme included the Belgian Scientific Programme on Antarctic Research. The International Polar Foundation, an organization led by the civil engineer and explorer Alain Hubert, was commissioned by the Belgian Federal government in 2004 to design, construct and operate a new Belgian Antarctic Research Station as an element under this umbrella programme. The station was to be designed as a central location for investigating the characteristic sequence of Antarctic geographical regions (polynia, coast, ice shelf, ice sheet, marginal mountain area and dry valleys, inland plateau) within a radius of 200 kilometers (approx.124 miles) of a selected site. The station was also to be designed as "state of the art" with respect to sustainable development, energy consumption, and waste disposal, with a minimum lifetime of 25 years. The goal of the project was to build a station and enable science. So first we needed some basic requirements, which I have listed here; plus we had to finance the station ourselves. Our most important requirement was that we decided to make it a zero emissions station. This was both a philosophical choice as we thought it more consistent with Antarctic Treaty obligations and it was also a logistical advantage. If you are using renewable energy sources, you do not have to bring in all the fuel.

    transferred over to a new Excel worksheet for comparison. I managed to get my application to acquire the CSWG (Computer Safety Working Group) and the SPNWG (Space Station Working Group) SPN's with just two mouse clicks for each pull, as opposed to several from the original process. When all three pulls are performed, an Excel sheet containing all three different results will be generated for the user to compare and determine which SPN's will be presented or reviewed the following month. The experience from this internship has been spectacular. As a high school senior who will begin attending college in the fall, this internship has been both educationally and occupationally beneficial. The internship has allowed me the opportunities to learn new programming languages, effectively network with NASA personnel from a variety of departments at JSC, and allowed me to learn new professional skills and etiquette. My internship at NASA's Johnson Space Center has further motivated me to pursue a Master's degree in Software Engineering and strive for a prosperous career with NASA as a civil servant.

  9. Day-care attendance and child development:

    Bauchmüller, Robert; Gørtz, Mette; Rasmussen, Astrid Würtz

    Earlier research suggests that children’s development is shaped in their early years of life. This paper examines whether differences in day-care experiences during pre-school age are important for children’s cognitive and language development at the age of 15.

  11. Attending to music decreases inattentional blindness.

    Beanland, Vanessa; Allen, Rosemary A; Pammer, Kristen

    2011-12-01

    This article investigates how auditory attention affects inattentional blindness (IB), a failure of conscious awareness in which an observer does not notice an unexpected event because their attention is engaged elsewhere. Previous research using the attentional blink paradigm has indicated that listening to music can reduce failures of conscious awareness. It was proposed that listening to music would decrease IB by reducing observers' frequency of task-unrelated thoughts (TUTs). Observers completed an IB task that varied both visual and auditory demands. Listening to music was associated with significantly lower IB, but only when observers actively attended to the music. Follow-up experiments suggest this was due to the distracting qualities of the audio task. The results also suggest a complex relationship between IB and TUTs: during demanding tasks, as predicted, noticers of the unexpected stimulus reported fewer TUTs than non-noticers. During less demanding tasks, however, noticers reported more TUTs than non-noticers.

  12. UMTS Network Stations

    Hernandez, C.

    2010-09-01

    The weakness of small island electrical grids implies a handicap for the electrical generation with renewable energy sources. With the intention of maximizing the installation of photovoltaic generators in the Canary Islands, arises the need to develop a solar forecasting system that allows knowing in advance the amount of PV generated electricity that will be going into the grid, from the installed PV power plants installed in the island. The forecasting tools need to get feedback from real weather data in "real time" from remote weather stations. Nevertheless, the transference of this data to the calculation computer servers is very complicated with the old point to point telecommunication systems that, neither allow the transfer of data from several remote weather stations simultaneously nor high frequency of sampling of weather parameters due to slowness of the connection. This one project has developed a telecommunications infrastructure that allows sensorizadas remote stations, to send data of its sensors, once every minute and simultaneously, to the calculation server running the solar forecasting numerical models. For it, the Canary Islands Institute of Technology has added a sophisticated communications network to its 30 weather stations measuring irradiation at strategic sites, areas with high penetration of photovoltaic generation or that have potential to host in the future photovoltaic power plants connected to the grid. In each one of the stations, irradiance and temperature measurement instruments have been installed, over inclined silicon cell, global radiation on horizontal surface and room temperature. Mobile telephone devices have been installed and programmed in each one of the weather stations, which allow the transfer of their data taking advantage of the UMTS service offered by the local telephone operator. Every minute the computer server running the numerical weather forecasting models receives data inputs from 120 instruments distributed

  13. The Space Station

    Sharples, R.; Hieatt, J.

    1984-11-01

    The configuration of the Space Station under design studies by NASA is limited only by the capabilities of the Shuttle and the purposes to which it is applied. Once the standard interlocks, launch vibration modes, and pallet designs are fixed, all other assembly of modular components, testing, and trim will be performed in space. The Station will serve for long-term experiments, as a base for planetary missions asembly, launch, and retrieval, and for loading and launching multiple satellites on an orbital transfer vehicle. Materials processing research will be carried out in the Station, as will various scientific and commercial remote sensing activities. The first operational version (1990) will require four Shuttle launches to reach an assembled mass of 70,000 kg drawing 30 kWe from solar panels and housing a crew of five. By the year 2000 the station will support 10-12 crew members in five habitat modules, will be 31 m long, will have cost $18-20 billion, and will be returning $2 billion per year. The station will be periodically reboosted to higher orbits that decay suficiently for orbiter rendezvous for supplies and assignments.

  14. Os efeitos da aplicação dos royalties petrolíferos sobre os investimentos públicos nos municípios brasileiros

    Diego Araujo Reis

    2015-02-01

    Full Text Available A promulgação da Lei no 9.478, de 1997, proporcionou um maior ingresso de royalties provenientes da exploração de petróleo e gás natural em alguns municípios brasileiros. Por ser uma receita transitória, é relevante investigar a aplicação desses recursos, da perspectiva das finanças públicas. Este artigo tem como objetivo analisar os efeitos da aplicação dos royalties petrolíferos sobre os investimentos públicos nos municípios brasileiros, no período de 1999 a 2011. A estratégia metodológica envolveu o uso do modelo econométrico de painel, a partir da utilização das variáveis receitas orçamentárias, royalties e despesas de capital dos respectivos municípios, obtidas a partir de fontes secundárias. Os resultados mostram que os municípios mais dependentes dos royalties elevaram as despesas de capital com o aumento dos royalties, tanto pela ótica per capita como pela proporção fiscal.

  15. Algorithm for Efficient Attendance management: Face Recognition based approach

    Naveed Khan Baloch

    2012-07-01

    Full Text Available Students attendance in the classroom is very important task and if taken manually wastes a lot of time. There are many automatic methods available for this purpose i.e. biometric attendance. All these methods also waste time because students have to make a queue to touch their thumb on the scanning device. This work describes the efficient algorithm that automatically marks the attendance without human intervention. This attendance is recorded by using a camera attached in front of classroom that is continuously capturing images of students, detect the faces in images and compare the detected faces with the database and mark the attendance. The paper review the related work in the field of attendance system then describes the system architecture, software algorithm and results.

This involves...... a transfer station where the transfer takes place. These stations may also be accessible by private people, offering flexibility to the waste system, including facilities for bulky waste, household hazardous waste and recyclables. Waste transfer may also take place on the collection route from small...... satellite collection vehicles to large compacting vehicles that cannot effectively travel small streets and alleys within the inner city or in residential communities with narrow roads. However, mobile transfer is not dealt with in this chapter, which focuses on stationary transfer stations. This chapter...

  17. Hydrogen vehicle fueling station

    Daney, D.E.; Edeskuty, F.J.; Daugherty, M.A. [Los Alamos National Lab., NM (United States)] [and others

    1995-09-01

    Hydrogen fueling stations are an essential element in the practical application of hydrogen as a vehicle fuel, and a number of issues such as safety, efficiency, design, and operating procedures can only be accurately addressed by a practical demonstration. Regardless of whether the vehicle is powered by an internal combustion engine or fuel cell, or whether the vehicle has a liquid or gaseous fuel tank, the fueling station is a critical technology which is the link between the local storage facility and the vehicle. Because most merchant hydrogen delivered in the US today (and in the near future) is in liquid form due to the overall economics of production and delivery, we believe a practical refueling station should be designed to receive liquid. Systems studies confirm this assumption for stations fueling up to about 300 vehicles. Our fueling station, aimed at refueling fleet vehicles, will receive hydrogen as a liquid and dispense it as either liquid, high pressure gas, or low pressure gas. Thus, it can refuel any of the three types of tanks proposed for hydrogen-powered vehicles -- liquid, gaseous, or hydride. The paper discusses the fueling station design. Results of a numerical model of liquid hydrogen vehicle tank filling, with emphasis on no vent filling, are presented to illustrate the usefulness of the model as a design tool. Results of our vehicle performance model illustrate our thesis that it is too early to judge what the preferred method of on-board vehicle fuel storage will be in practice -- thus our decision to accommodate all three methods.

    not had a mass mammogram recently, but who regularly visited gynaecologists, attended for Pap smear screening, practised breast self examination, and who did not smoke. Low confidence in their own capabilities in breast cancer prevention, overoptimism about the sensitivity of mammography, and perception...... of breast cancer risk as moderate were also predictive of attendance. Expectation of pain at mammography was predictive of non-attendance. CONCLUSION: Mammography screening organised as a public health service was well accepted. A recent mammogram, high reliance on self control of breast cancer......, and an expectation of pain at mammography deterred attendance at screening. Further information about these factors and health information on screening are needed....

  4. Kiowa Creek Switching Station

    1990-03-01

    The Western Area Power Administration (Western) proposes to construct, operate, and maintain a new Kiowa Creek Switching Station near Orchard in Morgan County, Colorado. Kiowa Creek Switching Station would consist of a fenced area of approximately 300 by 300 feet and contain various electrical equipment typical for a switching station. As part of this new construction, approximately one mile of an existing 115-kilovolt (kV) transmission line will be removed and replaced with a double circuit overhead line. The project will also include a short (one-third mile) realignment of an existing line to permit connection with the new switching station. In accordance with the Council on Environmental Quality (CEQ) regulations for implementing the procedural provisions of the National Environmental Policy Act of 1969 (NEPA), 40 CFR Parts 1500--1508, the Department of Energy (DOE) has determined that an environmental impact statement (EIS) is not required for the proposed project. This determination is based on the information contained in this environmental assessment (EA) prepared by Western. The EA identifies and evaluates the environmental and socioeconomic effects of the proposed action, and concludes that the advance impacts on the human environment resulting from the proposed project would not be significant. 8 refs., 3 figs., 1 tab.

  5. Perceptual organization at attended and unattended locations

    HAN; Shihui; Glyn; W.; Humphreys

    2005-01-01

    This study examined the effects of attention on forming perceptual units by proximity grouping and by uniform connectedness (UC). In Experiment 1 a row of three global letters defined by either proximity or UC was presented at the center of the visual field. Participants were asked to identify the letter in the middle of stimulus arrays while ignoring the flankers. The stimulus onset asynchrony (SOA) between stimulus arrays and masks varied between 180 and 500 ms. We found that responses to targets defined by proximity grouping were slower than to those defined by UC at median SOAs but there were no differences at short or long SOAs. Incongruent flankers slowed responses to targets and this flanker compatibility effect was larger for UC than for proximity-defined flankers. Experiment 2 examined the effects of spatial precueing on discrimination responses to proximity- and UC-defined targets. The advantage for targets defined by UC over targets defined by proximity grouping was greater at uncued relative to cued locations. The results suggest that the advantage for UC over proximity grouping in forming perceptual units is contingent on the stimuli not being fully attended, and that paying attention to the stimuli differentially benefits proximity grouping.

  10. Computer program for the automated attendance accounting system

    Poulson, P.; Rasmusson, C.

    1971-01-01

    The automated attendance accounting system (AAAS) was developed under the auspices of the Space Technology Applications Program. The task is basically the adaptation of a small digital computer, coupled with specially developed pushbutton terminals located in school classrooms and offices for the purpose of taking daily attendance, maintaining complete attendance records, and producing partial and summary reports. Especially developed for high schools, the system is intended to relieve both teachers and office personnel from the time-consuming and dreary task of recording and analyzing the myriad classroom attendance data collected throughout the semester. In addition, since many school district budgets are related to student attendance, the increase in accounting accuracy is expected to augment district income. A major component of this system is the real-time AAAS software system, which is described.

  11. The use of positive reinforcement in conditioning attending behavior.

    Walker, H M; Buckley, N K

    1968-01-01

    Individual conditioning techniques were applied in a controlled setting to increase attending behavior of an underachieving 9-yr-old male subject. The procedure involved: (1) determining a stable response pattern, (2) introducing a treatment variable to establish a high rate of task-attending behavior, (3) measuring the effect of withdrawal of the treatment variable after attaining criterion performance, and (4) transferring control to the classroom. The interval of attending behavior required for reinforcement was systematically increased from 30 sec to 600 sec as the behavior came under experimental control. Manipulating the reinforcing contingencies measurably changed the proportion of attending behavior and the frequency and duration of non-attending events. Once the behaviors were under experimental control, procedures were established to program generalization and to maintain the behavior outside the experimental setting.

    Full Text Available

    Background: The European Community recommends mammography, cervical and colorectal cancer screening programmes. In Italy, cancer screening programmes have been included in the Basic Healthcare Parameters (Livelli Essenziali di Assistenza since 2001. Full national coverage of a population-based organized screening programme has been planned for in Italy and is being implemented. Since 2005, the Ministry of Health - Department of Prevention has formally charged The National Centre for Screening Monitoring (Osservatorio Nazionale Screening –ONS- with monitoring and promoting screening programmes nationwide. Participation of target populations is a key indicator of the impact and efficacy of a screening programme in reducing cancer mortality.

    Methods: Attendance of invitees is one of the indicators calculated every year in the quality control of Italian screening programmes. Data collection is organized by means of a structured questionnaire, sent by ONS to the referent for data collection in each Region, who then returns the completed questionnaires to the Regional Centre. Questionnaires are then sent to the National Centre. Logical and epidemiologic checks are performed at both levels. Every year ONS publishes reports on the results of the surveys. A feasibility study for a National data warehouse based on individual records is in progress. The national survey “Multiscopo sulle famiglie” and the Passi Study (Progetti delle Aziende Sanitarie per la Salute in Italia provided additional information regarding spontaneous preventive health care activities in the Italian population.

    Results: Mammography screening: In 2006, 78.2% of Italian women aged 50-69 lived in areas where organised screening was in place (theoretical extension, however, the distribution of the screening activity is not uniform (higher in Northern/Central Italy compared with Southern

  1. Battery charging stations

    Bergey, M.

    1997-12-01

    This paper discusses the concept of battery charging stations (BCSs), designed to service rural owners of battery power sources. Many such power sources now are transported to urban areas for recharging. A BCS provides the opportunity to locate these facilities closer to the user, is often powered by renewable sources, or hybrid systems, takes advantage of economies of scale, and has the potential to provide lower cost of service, better service, and better cost recovery than other rural electrification programs. Typical systems discussed can service 200 to 1200 people, and consist of stations powered by photovoltaics, wind/PV, wind/diesel, or diesel only. Examples of installed systems are presented, followed by cost figures, economic analysis, and typical system design and performance numbers.

  6. Transition to skilled birth attendance: is there a future role for trained traditional birth attendants?

    Sibley, Lynn M; Sipe, Theresa Ann

    2006-12-01

    A brief history of training of traditional birth attendants (TBAs), summary of evidence for effectiveness of TBA training, and consideration of the future role of trained TBAs in an environment that emphasizes transition to skilled birth attendance are provided. Evidence of the effectiveness of TBA training, based on 60 studies and standard meta-analytic procedures, includes moderate-to-large improvements in behaviours of TBAs relating to selected intrapartum and postnatal care practices, small significant increases in women's use of antenatal care and emergency obstetric care, and small significant decreases in perinatal mortality and neonatal mortality due to birth asphyxia and pneumonia. Such findings are consistent with the historical focus of TBA training on extending the reach of primary healthcare and a few programmes that have included home-based management of complications of births and the newborns, such as birth asphyxia and pneumonia. Evidence suggests that, in settings characterized by high mortality and weak health systems, trained TBAs can contribute to the Millennium Development Goal 4--a two-thirds reduction in the rate of mortality of children aged less than 14 years by 2015--through participation in key evidence-based interventions.

  12. A comparative study of the elemental composition of the exhaust emissions of cars powered by liquefied petroleum gas and unleaded petrol

    Lim, McKenzie C. H.; Ayoko, Godwin A.; Morawska, Lidia; Ristovski, Zoran D.; Jayaratne, E. Rohan; Kokot, Serge

    Elements emitted from the exhausts of new Ford Falcon Forte cars powered by unleaded petrol (ULP) and liquefied petroleum gas (LPG) were measured on a chassis dynamometer. The measurements were carried out in February, June and August 2001, and at two steady state driving conditions (60 and 80 km h -1). Thirty seven elements were quantified in the exhaust samples by inductively coupled plasma mass spectrometry (ICPMS). The total emission factors of the elements from the exhausts of ULP cars were higher than those of LPG cars at both engine speeds even though high variability in the exhaust emissions from different cars was noted. The effect of the operating conditions such as mileage of the cars, engine speed, fuel and lubricating oil compositions on the emissions was studied. To investigate the effects of these conditions, multivariate data analysis methods were employed including exploratory principal component analysis (PCA), and the multi-criteria decision making methods (MCDM), preference ranking organization method for enrichment evaluation (PROMETHEE) and geometrical analysis for interactive aid (GAIA), for ranking the cars on the basis of the emission factors of the elements. PCA biplot of the complete data matrix showed a clear discrimination of the February, June and August emission test results. In addition, (i) platinum group elements (PGE) emissions were separated from each other in the three different clusters viz. Pt with February, Pd with June and Rh with August; (ii) the motor oil related elements, Zn and P, were particularly associated with the June and August tests (these vectors were also grouped with V, Al and Cu); and (iii) highest emissions of most major elements were associated with the August test after the cars have recorded their highest mileage. Extensive analysis with the aid of the MCDM ranking methods demonstrated clearly that cars powered by LPG outperform those powered by ULP. In general, cars tested in June perform better than

Nesta perspectiva, utilizar ferramentas que auxiliem no processo de análise dos estudos realizados in loco são imprescindíveis para que sejam auferidas interpretações mais precisas. Em virtude da heterogeneidade multiescala dos reservatórios de petróleo, a obtenção de propriedades equivalentes das formações rochosas mais finas resulta em uma problemática, pois elas são variáveis. Nesse sentido, as Wavelets são funções desenvolvidas através de diversas áreas: a matemática, a física quântica, a engenharia e a geologia, que permitem o tratamento de dados coletados na área de estudo e conferem um teor de maior concisão à pesquisa, visto que por meio delas acontece a decomposição multiescala e, consequentemente, uma adequação no processamento de propriedades de rochas e fluxo em um reservatório com heterogeneidades em várias escalas. Esse trabalho tem como finalidade analisar a utilização das Wavelets no processo de investigação do subsolo, mais especificamente na detecção de hidrocarbonetos. Para isso, foi feita uma pesquisa bibliográfica dos assuntos inerentes à temática e considerados os elementos relevantes para esta pesquisa. Verifica-se que as Wavelets contribuem para a efetividade das investigações geofísicas, tendo grande aplicabilidade na exploração petrolífera, uma vez que possibilita a descrição de condições geológicas de intervenção de maneira mais segura, e garantindo melhores resultados de aferições.

  14. School Attendance and Child Labor - A Model of Collective Behavior

    Strulik, Holger

    2010-01-01

    This paper theoretically investigates how community approval or disapproval affects school attendance and child labor and how aggregate behavior of the community feeds back towards the formation and persistence of an anti- (or pro-) schooling norm. The proposed community-model continues to take aggregate and idiosyncratic poverty into account as an important driver of low school attendance and child labor. But it provides also an explanation for why equally poor villages or regions can displa...

  19. Compressor station layout considerations

    Kurz, Rainer; Ohanian, Sebouh; Lubomirsky, Matt [Solar Turbines Incorporated, San Diego, CA (United States)

    2003-07-01

    This paper discusses issues that influence the decision on the arrangement of compressors and the type of equipment in gas pipeline compressor stations. Different concepts such as multiple small units versus single large units are considered, both regarding their impact on the individual station and the overall pipeline. The necessity of standby units is discussed. Various concepts for drivers (gas turbine, gas motor and electric motor) and compressors (centrifugal and reciprocating) are analyzed. The importance of considering all possible operating conditions is stressed. With the wide range of possible operating conditions for the pipeline in mind, the discussion is brought into the general context of operational flexibility, availability, reliability, installation issues, remote control, and operability of gas turbine driven centrifugal compressors compared to other solutions such as electric motor driven compressors or gas engine driven reciprocating compressors. The impact of different concepts on emissions and fuel cost is discussed. Among the assumptions in this paper are the performance characteristics of the compressor. This paper outlines how these performance characteristics influence the conclusions. (author)

  20. Radon and Thoron Measured in Petrol and Gas-oil Exhaust Fumes by Using CR-39 and LR-115 II Nuclear Track Detectors: Radiation Doses to the Respiratory Tract of Mechanic Workers.

    2015-06-01

    Mechanic workers are exposed to exhaust fumes when controlling vehicle engines in motion inside repair shops. To assess radiation doses due to radon short-lived progeny from the inhalation of exhaust fumes by mechanic workers, concentrations of these radionuclides were measured in petrol (gasoline) and gas-oil exhaust fumes by evaluating mean critical angles of etching of the CR-39 and LR-115 type II SSNTDs for alpha particles emitted by the radon and thoron decay series. Committed effective doses due to ²¹⁸Po and ²¹⁴Po short-lived radon decay products from the inhalation of petrol and gas-oil exhaust fumes by workers were evaluated. A maximum value of 1.35 mSv y⁻¹ due to radon short-lived decay products from the inhalation of gas-oil exhaust fumes by mechanic workers was found, which is lower than the (3-10 mSv y⁻¹) dose limit interval for workers.

  8. Mobile Attendance Checking System on Android Platform for Kazakhstani University

    Saparkhojayev, N.; Shakhov, E.; Mailybayev, Y.

    2016-04-01

    In the 21st century-the century of Information Technology, it is difficult to imagine life without any gadgets: phones, tablets, computers, laptops, and so on. Today, smartphones and tablets are becoming popular, and thus their operating systems become popular too. Android is designed for low-power devices that run on battery power at full capacity, using all of its services, such as cameras, lights, GPS navigation, Wi-Fi, etc. In Kazakhstani universities, the process of checking students’ attendance is one of the important issues, because final grade evaluation of students is based on their total number of appearances and their grades during the whole semester. This raises the question of having some tool to control students’ attendance. There are many possible ways of controlling attendance: there are many examples when universities prefer to control attendance by the use of paper sheet, and some universities prefer to use two-stage way of controlling attendance: firstly, teachers and professors use paper sheet for checking students’ attendance and after this, they fill out these information into a system manually. However, this is not an efficient way since there will be spent much of time for calling students names and putting marks like “presence” or “absence” if the class is a lecture class, and in this class at least 5 groups are presented. Furthermore, some students may call his/her friend as “presence” nevertheless to the fact that this student is currently absent. After taking into consideration all these issues and the fact that many gadgets use Android platform, authors of the following research paper decided to create a mobile system that makes easier to check students’ attendance automatically, and this system is implemented in Almaty Management University, Kazakhstan. The system is based on Android platform, and in this paper, details of this system are presented.

  9. Evidence for a fixed capacity limit in attending multiple locations.

    Ester, Edward F; Fukuda, Keisuke; May, Lisa M; Vogel, Edward K; Awh, Edward

    2014-03-01

    A classic question concerns whether humans can attend multiple locations or objects at once. Although it is generally agreed that the answer to this question is "yes," the limits on this ability are subject to extensive debate. According to one view, attentional resources can be flexibly allocated to a variable number of locations, with an inverse relationship between the number of selected locations and the quality of information processing at each location. Alternatively, these resources might be quantized in a "discrete" fashion that enables concurrent access to a small number of locations. Here, we report a series of experiments comparing these alternatives. In each experiment, we cued participants to attend a variable number of spatial locations and asked them to report the orientation of a single, briefly presented target. In all experiments, participants' orientation report errors were well-described by a model that assumes a fixed upper limit in the number of locations that can be attended. Conversely, report errors were poorly described by a flexible-resource model that assumes no fixed limit on the number of locations that can be attended. Critically, we showed that these discrete limits were predicted by cue-evoked neural activity elicited before the onset of the target array, suggesting that performance was limited by selection processes that began prior to subsequent encoding and memory storage. Together, these findings constitute novel evidence supporting the hypothesis that human observers can attend only a small number of discrete locations at an instant.

Foram coletadas amostras de solo nas profundidades de 0 a 20 cm e de 20 a 40 cm. Foram estabelecidas 100 parcelas de 1×1 m em cada área e coletadas todas as espécies herbáceas. De modo geral, o solo da área do embasamento cristalino foi mais fértil, raso, com maior capacidade de reter água e maior porcentagem de argila. Os números de famílias, gêneros e espécies das áreas da bacia sedimentar e do embasamento cristalino foram 32, 62 e 78 e 31, 53 e 69, respectivamente. A similaridade florística entre as áreas foi alta (75%. A análise de agrupamento mostrou que os arranjos florísticos entre as parcelas amostradas são mais semelhantes dentro de cada área que entre áreas, sugerindo a existência de grupos distintos. Tipo de solo parece não ser um fator decisivo na similaridade florística, hábito e proporção de forma de vida das herbáceas da vegetação da caatinga quando as áreas são próximas, mas pode influenciar a ocorrência e a freqüência de algumas espécies.Floristic surveys were carried out in two close caatinga areas, one on the crystalline shield and the other on a sedimentary basin, both at Petrolândia, Pernambuco, Brazil, with the objective of identifying differences between the two areas in composition, habit and life form of the herbaceous flora.

The solar plant will be attached to a 1440 MW(e) coal fired plant. The 17000 m{sup 2} array will be the largest array in Australia, producing a peak of 13 MW of thermal energy which will offset the use of coal in the generation of electricity. It will use direct steam generation and will feed either steam or hot water at 265 Celsius degrees directly into the power station preheating cycle. The CLFR system, first developed by the University of Sidney and Solsearch Pty. Ltd., is simple and offers small reflector size, low structural cost, fixed receiver geometry. Initial installed plant costs are approximately US$1000 per kWe, but this includes the effect of high up-front design costs and the cost should drop substantially in the second and subsequent plants.

    2014-02-01

    Full Text Available Introduction: Several prior studies have examined the impact of learners (medical students or residents on overall emergency department (ED flow as well as the impact of resident training level on the number of patients seen by residents per hour. No study to date has specifically examined the impact of learners on emergency medicine (EM attending physician productivity, with regards to patients per hour (PPH. We sought to evaluate whether learners increase, decrease, or have no effect on the productivity of EM attending physicians in a teaching program with one student or resident per attending.Methods: This was a retrospective database review of an urban, academic tertiary care center with 3 separate teams on the acute care side of the ED. Each team was staffed with one attending physician paired with either one resident, one medical student or with no learners. All shifts from July 1, 2008 to June 30, 2010 were reviewed using an electronic database. We predefined a shift as “Resident” if > 5 patients were seen by a resident, “Medical Student” if any patients were seen by a medical student, and “No Learners” if no patients were seen by a medical student or resident. Shifts were removed from analysis if more than one learner saw patients during the shift. We further stratified resident shifts by EM training level or off-service rotator. For each type of shift, the total number of patients seen by the attending physician was then divided by 8 hours (shift duration to arrive at number of patients per hour. Results: We analyzed a total of 7,360 shifts with 2,778 removed due to multiple learners on a team. For the 2,199 shifts with attending physicians with no learners, the average number of PPH was 1.87(95% confidence interval [CI] 1.86,1.89. For the 514 medical student shifts, the average PPH was 1.87(95% CI 1.84,1.90, p = 0.99 compared with attending with no learner. For the 1,935 resident shifts, the average PPH was 1.99(95% CI 1

    Full Text Available This research involves an android application in attendance management system. The study sought to provide an alternative solution to the increasing demand for time management in the College of Engineering and Computing Sciences in Batangas State University ARASOF. Through the said Android application the attendance checking will be much easier, for it will reduce the roll call that takes a lot of time. It was developed to help the lecturers have sufficient time for teaching and the students for learning. The researchers used research design, development process, and programming procedures in their study. The “Attendroid”, was designed and develop using Eclipse, Java Script, Php and HTML. This application is for android phones and tablet which has portable hotspot. The android application for the students will run on 2.2versions of android and higher. The android application has gone through an evaluation to test whether the system is acceptable in terms of security, accuracy, reliability, maintainability and user-friendliness against the manual checking of attendance. The result shows that the respondents are more favorable in the Attendroid because it can be gleaned that they gave an excellent feedback to the application compared to the manual process of attendance checking. After thorough study of the old ways of attendance checking against the newly developed application, a necessity to improve the manual checking was observed, and therefore, strengthen the advantages of implementing Attendroid. Based on the result of the proposed users’ acceptability, Attendroid could become the formal attendance checking system of the College of Engineering and Computing Sciences.

  16. Weather and Tourism: Thermal Comfort and Zoological Park Visitor Attendance

    David R. Perkins

    2016-03-01

    Full Text Available Weather events have the potential to greatly impact business operations and profitability, especially in outdoor-oriented economic sectors such as Tourism, Recreation, and Leisure (TRL. Although a substantive body of work focuses on the macroscale impacts of climate change, less is known about how daily weather events influence attendance decisions, particularly relating to the physiological thermal comfort levels of each visitor. To address this imbalance, this paper focuses on ambient thermal environments and visitor behavior at the Phoenix and Atlanta zoos. Daily visitor attendances at each zoo from September 2001 to June 2011, were paired with the Physiologically Equivalent Temperature (PET to help measure the thermal conditions most likely experienced by zoo visitors. PET was calculated using hourly atmospheric variables of temperature, humidity, wind speed, and cloud cover from 7 a.m. to 7 p.m. at each zoological park location and then classified based on thermal comfort categories established by the American Society of Heating and Air Conditioning Engineers (ASHRAE. The major findings suggested that in both Phoenix and Atlanta, optimal thermal regimes for peak attendance occurred within “slightly warm” and “warm” PET-based thermal categories. Additionally, visitors seemed to be averse to the most commonly occurring thermal extreme since visitors appeared to avoid the zoo on excessively hot days in Phoenix and excessively cold days in Atlanta. Finally, changes in the daily weather impacted visitor attendance as both zoos experienced peak attendance on days with dynamic changes in the thermal regimes and depressed attendances on days with stagnant thermal regimes. Building a better understanding of how weather events impact visitor demand can help improve our assessments of the potential impacts future climate change may have on tourism.

  9. WVU Hydrogen Fuel Dispensing Station

    Davis, William [West Virginia University Research Corporation, Morgantown, WV (United States)

    2015-09-01

    The scope of this project was changed during the course of the project. Phase I of the project was to construct a site similar to the site at Central West Virginia Regional Airport in Charleston, WV to show that duplication of the site was a feasible method of conducting hydrogen stations. Phase II of the project was necessitated due to a lack of funding that was planned for the development of the station in Morgantown. The US Department of Energy determined that the station in Charleston would be dismantled and moved to Morgantown and reassembled at the Morgantown site. This necessitated storage of the components of the station for almost a year at the NAFTC Headquarters which caused a number of issues with the equipment that will be discussed in later portions of this report. This report will consist of PHASE I and PHASE II with discussions on each of the tasks scheduled for each phase of the project.

  20. TEACHING, COEXISTENCE AND ATTENDANCE AT A TECHNOLOGICAL HIGH SCHOOL

    Leticia Carranza-Peña

    2015-01-01

    Full Text Available This article, which stems from ethnographic research, shows the importance of faculty intervention in the classroom setting in encouraging student attendance. Our findings indicate that the habitus the educator establishes can either encourage youth to continue their studies, or lead them to drop out, thus placing them at risk of addictions, illegal activities, unemployment or low-paid jobs. The Pedagogy of Hope therefore provides an option for effecting large-scale changes in personal, school, family, community and socio-economic conditions. The paper’s conclusions include providing training to teaching faculties on coexistence issues; ensuring coordination between school and family, and emphasizing an integral approach to education as means of promoting school attendance.

    Full Text Available The purpose of this study is to investigate creativity among children attending preschools in terms of several variables. The study was conducted with 72 female and 63 male 5-year-old (60-72 months children selected from independent preschools related to the Turkish Ministry of National Education in Ankara. The “General Information Form” was administered to children in order to collect basic information about children and their parents. To determine creativity among children, the “Torrence Creative Thinking Test” developed by Torrence in 1966 and translated into Turkish by Aslan (1999 was used. Mann-Whitney U and Kruskall-Wallis H tests were used to analyze data. As a result of the study, gender and father’s educational level do not affect creativity scores of the children, yet duration of preschool attendance and mother’s educational level statistically have a significant effect on their creativity scores (p<.05.

  2. Introduction to Space Station Freedom

    Kohrs, Richard

    NASA field centers and contractors are organized to develop 'work packages' for Space Station Freedom. Marshall Space Flight Center and Boeing are building the U.S. laboratory and habitation modules, nodes, and environmental control and life support system; Johnson Space Center and McDonnell Douglas are responsible for truss structure, data management, propulsion systems, thermal control, and communications and guidance; Lewis Research Center and Rocketdyne are developing the power system. The Canadian Space Agency (CSA) is contributing a Mobile Servicing Center, Special Dextrous Manipulator, and Mobile Servicing Center Maintenance Depot. The National Space Development Agency of Japan (NASDA) is contributing a Japanese Experiment Module (JEM), which includes a pressurized module, logistics module, and exposed experiment facility. The European Space Agency (ESA) is contributing the Columbus laboratory module. NASA ground facilities, now in various stages of development to support Space Station Freedom, include: Marshall Space Flight Center's Payload Operations Integration Center and Payload Training Complex (Alabama), Johnson Space Center's Space Station Control Center and Space Station Training Facility (Texas), Lewis Research Center's Power System Facility (Ohio), and Kennedy Space Center's Space Station Processing Facility (Florida). Budget appropriations impact the development of the Space Station. In Fiscal Year 1988, Congress appropriated only half of the funds that NASA requested for the space station program ($393 million vs. $767 million). In FY 89, NASA sought $967 million for the program, and Congress appropriated $900 million. NASA's FY 90 request was $2.05 billion compared to an appropriation of $1.75 billion; the FY 91 request was $2.45 billion, and the appropriation was $1.9 billion. After NASA restructured the Space Station Freedom program in response to directions from Congress, the agency's full budget request of $2.029 billion for Space Station

    2015-01-01

    Incomplete vaccination for patients with type 2 diabetes attending non-communicable diseases (NCD) clinics is an issue that could affect patient's health and wellness negatively and puts patients at high risk of serious diseases. We aimed to improve physicians adherence to complete vaccination schedule for patients with type 2 diabetes attending NCD clinics in west bay health center according to American Diabetes Association (ADA) recommendation by 25% by January 2015. In the pre-intervention phase: the quality improvement team designed a checklist to collect the percentage of physician's adherence of prescription of the recommended vaccination for patients with type 2 diabetes. The percentage of complete vaccination in patients with diabetes attending NCD clinic in West Bay Health Center was 20% . In the intervention phase the intervention was in the form of: the creation a vaccination form and attached to the (NCD) progress note; to distribute and remind the physicians about the ADA guidelines vaccination recommendations; a summary of the vaccination schedule developed and attached to (NCD) form; development of vaccination reminder posters and posters in the waiting area, nurse station, and physician clinics and education and orientation sessions for NCD clinic staff. In the post-intervention phase the average percentage of complete vaccination in patients with diabetes attending NCD clinic in West Bay Health Center increased to 69%.

  11. Delivery practices of traditional birth attendants in Dhaka slums, Bangladesh.

    Fronczak, N; Arifeen, S E; Moran, A C; Caulfield, L E; Baqui, A H

    2007-12-01

    This paper describes associations among delivery-location, training of birth attendants, birthing practices, and early postpartum morbidity in women in slum areas of Dhaka, Bangladesh. During November 1993-May 1995, data on delivery-location, training of birth attendants, birthing practices, delivery-related complications, and postpartum morbidity were collected through interviews with 1,506 women, 489 home-based birth attendants, and audits in 20 facilities where the women from this study gave birth. Associations among maternal characteristics, birth practices, delivery-location, and early postpartum morbidity were specifically explored. Self-reported postpartum morbidity was associated with maternal characteristics, delivery-related complications, and some birthing practices. Dais with more experience were more likely to use potentially-harmful birthing practices which increased the risk of postpartum morbidity among women with births at home. Postpartum morbidity did not differ by birth-location. Safe motherhood programmes must develop effective strategies to discourage potentially-harmful home-based delivery practices demonstrated to contribute to morbidity.

    Full Text Available Introduction: In INDIA almost 20000 people die (40% of world death each year from rabies. Most of these deaths could be prevented by post exposure prophylaxis with wound washing, rabies immunoglobulin & vaccination. Local wound management alone can reduce viral load by up to 80%. Objective: To study self-wound management practices in animal exposure patients before attending a tertiary level ARV clinic. Methodology: Data regarding wound management was collected by individual interview of patients attending the ARV clinic during OCT 2011 to MAR 2012. The data collected in the form of a questionnaire. Analysis of data was done in the Department Of Community Medicine, V.S.S. Medical College, Burla. Results: Total 493 cases of animal exposure were attended during the study period. Most common biting animal was dog (94.5%. 31% of cases were under the age of 10 years & 23% belongs to the age of 10-19 years. Male to female ratio was 3:1. Most of the cases (91% were of category III exposure. Immediate management of wound was practiced by 63-77% of cases before visiting ARV clinic; only 2% wash the wound with running water & soap for 15 minutes. 39% of cases applied Dettol/savlon at the wound side & other 38% applied turmeric, red chilli, kerosene, Band-Aid & ghee locally. Most cases (61% reported to ARV clinic within 24hours.

  13. A theory of attending and reinforcement in conditional discriminations.

    Nevin, John A; Davison, Michael; Shahan, Timothy A

    2005-09-01

    A model of conditional discrimination performance (Davison & Nevin, 1999) is combined with the notion that unmeasured attending to the sample and comparison stimuli, in the steady state and during disruption, depends on reinforcement in the same way as predicted for overt free-operant responding by behavioral momentum theory (Nevin & Grace, 2000). The rate of observing behavior, a measurable accompaniment of attending, is well described by an equation for steady-state responding derived from momentum theory, and the resistance to change of observing conforms to predictions of momentum theory, supporting a key assumption of the model. When probabilities of attending are less than 1.0, the model accounts for some aspects of conditional-discrimination performance that posed problems for the Davison-Nevin model: (a) the effects of differential reinforcement on the allocation of responses to the comparison stimuli and on accuracy in several matching-to-sample and signal-detection tasks where the differences between the stimuli or responses were varied across conditions, (b) the effects of overall reinforcer rate on the asymptotic level and resistance to change of both response rate and accuracy of matching to sample in multiple schedules, and (c) the effects of fixed-ratio reinforcement on accuracy. Some tests and extensions of the model are suggested, and the role of unmeasured events in behavior theory is considered.

  14. In situ radio-frequency heating for soil remediation at a former service station: case study and general aspects

    Huon, G.; Simpson, T.; Maini, G. [Ecologia Environmental Solutions Ltd., Sittingbourne, Kent (United Kingdom); Holzer, F.; Kopinke, F.D.; Roland, U. [Helmholtz Centre for Environmental Research - UFZ, Department of Environmental Engineering, Leipzig (Germany); Will, F. [Total UK, Watford (United Kingdom)

    2012-08-15

    In situ radio-frequency heating (ISRFH) was successfully applied during remediation of a former petrol station. Using a three-electrode array in combination with extraction wells for soil vapor extraction (SVE), pollution consisting mainly of benzene, toluene, ethylbenzene, xylenes, and mineral oil hydrocarbons (in total about 1100 kg) was eliminated from a chalk soil in the unsaturated zone. Specially designed rod electrodes allowed selective heating of a volume of approximately 480 m{sup 3}, at a defined depth, to a mean temperature of about 50 C. The heating drastically increased the extraction rates. After switching off ISRFH, SVE remained highly efficient for some weeks due to the heat-retaining properties of the soil. Comparison of an optimized regime of ISRFH/SVE with conventional ''cold'' SVE showed a reduction of remediation time by about 80 % while keeping the total energy consumption almost constant.

    Schaefer, K.; Hoffmann, H.; Emeis, S.; Jahn, C.; Sedlmaier, A.; Wilhelm, H.; Dormuth, I.

    2001-11-01

    The gas-free ventilation of the tanks of river tank ships by the common praxis to ventilate the tank atmosphere into ambient air is a big emission source of VOCs and a strong deterioration of air quality. It was shown during several measurement campaigns that the ventilation of the tank atmosphere of river tank ships via the loading / unloading pipes into the land-site vapour recovery unit is a technical solution. The measured emission source strengths during this type of ventilation are of the same amount as the measured emission source strengths during loading and unloading of petrol and are caused by attachment and detachment of loading / unloading pipes only. Furthermore, the concentrations of petrol in the tank atmosphere were measured by the PTB during these experiments. As result of the investigations a leaflet as instruction of environment friendly ventilation of tank atmosphere of river tank ships for the inland sailors and operators of tank storage plants was composed. On the basis of an inquiry of the available vapour recovery units the required capacity of land-site vapour recovery units for the replacement of all ventilation of tank atmosphere to open air was estimated. The capacity of the available vapour recovery units is too low for a preferably short time period of tank atmosphere ventilation. Solving this problem not only the enhancement of the capacity of the available vapour recovery units up to a capacity of 2,200 m{sup 3}/h must be considered but their availability at loading / unloading points of petrol as well as the availability of berthing place must be taken into account also. The necessary enhancement of the capacity and the number of possible new installations of vapour recovery units cannot be defined now because a new amendment for the execution of the 20. BImSchV came into force on 25 August 2001 which allows the ventilation of tank atmosphere of river tank ships to open air under certain conditions until 31 December 2005. To draw

  19. Relaciones entre la zonalidad petrológica y metalogénica de los macizos lerzolíticos de las cadenas alpinas del Mediterráneo Occidental (Cordillera Bético-Rifeña y Kabylias

    Torres-Ruiz, J.

    1988-12-01

    Full Text Available Gamet-lherzolite facies, Ariegite and Seiland subfacies of the spinel-lherzolite facies and plagioclase-lherzolite facies have been identified in the Serranía de Ronda, Beni Bousera and Collo lherzolitic massifs. These petrological facies occur in a zonal arrangement: gamet lherzolite are in contact with the overlaying metapelitic sequence and spinel then plagioclase lherzolite occur inwards, representing the innermost zones in the former mantle body. The various occurrences of mineralizations can be classified in two main groups: one of them is essentialIy made up of chromite and Ni arsenides with pyroxene and/or cordierite as gangue minerals; the other consists Qf Fe-Ni-Cu sulfides and graphite, with pyroxene, plagioclase and phlogopite as gangue minerals. In both groups, the ores with the more refractory composition were the first to crystallize in the hotter core of the diapir while those other with a more differentiated composition were formed later within the external zones. The close correlation between petrological and metallogenical roning supports a magmatic origin of the mineralizations related to the petrologic evolution of the mantle bodies. The mineralizing liquids• originated from magmas generated by partial melting of the peridotites. The former migrated outwards, from the internal part of the bodies, during which marked interaction with the enclosing rocks and complex fractionation processes took place under moderate to low pressure conditions.En los macizos lerzolíticos de la Serranía de Ronda, de Beni Bousera y de Collo se han identificado facies de lerzolitas con granate, facies de lerzolitas con espinela (subfacies Ariegita y Seiland y facies de lerzolitas con plagioclasa.

  5. Automatic Weather Station (AWS) Lidar

    Rall, Jonathan A.R.; Abshire, James B.; Spinhirne, James D.; Smith, David E. (Technical Monitor)

    2000-01-01

    An autonomous, low-power atmospheric lidar instrument is being developed at NASA Goddard Space Flight Center. This compact, portable lidar will operate continuously in a temperature controlled enclosure, charge its own batteries through a combination of a small rugged wind generator and solar panels, and transmit its data from remote locations to ground stations via satellite. A network of these instruments will be established by co-locating them at remote Automatic Weather Station (AWS) sites in Antarctica under the auspices of the National Science Foundation (NSF). The NSF Office of Polar Programs provides support to place the weather stations in remote areas of Antarctica in support of meteorological research and operations. The AWS meteorological data will directly benefit the analysis of the lidar data while a network of ground based atmospheric lidar will provide knowledge regarding the temporal evolution and spatial extent of Type la polar stratospheric clouds (PSC). These clouds play a crucial role in the annual austral springtime destruction of stratospheric ozone over Antarctica, i.e. the ozone hole. In addition, the lidar will monitor and record the general atmospheric conditions (transmission and backscatter) of the overlying atmosphere which will benefit the Geoscience Laser Altimeter System (GLAS). Prototype lidar instruments have been deployed to the Amundsen-Scott South Pole Station (1995-96, 2000) and to an Automated Geophysical Observatory site (AGO 1) in January 1999. We report on data acquired with these instruments, instrument performance, and anticipated performance of the AWS Lidar.

  15. Telemedicine in plastic surgery: E-consult the attending surgeon.

    Pap, Stephen A; Lach, Elliot; Upton, Joseph

    2002-08-01

    Telemedicine has evolved into a valuable but underused resource for the delivery of health care to patients at a distance, particularly where patient transport is impractical, expensive, complicated, and/or urgent. Today, over 250,000 telemedicine consults are generated annually, involving various specialties in both military and civilian health delivery systems. The ability to evaluate and triage plastic surgery patients through the use of telemedicine has not been widely explored. We have designed, developed, and tested a "store-and-forward" solution at UMass Memorial Hospital and Beth Israel Deaconess Hospital whereby the plastic surgery residents who responded to a consult request transmitted digital photographs by means of the Internet to the attending physician on call. The customary telephone call between resident and attending physician benefited from the additional photographic data, and patient management resulted in a clear, concise, and unambiguous treatment plan. The initial management suggested by the resident was modified on some occasions, particularly with complex problems. The use of digital images was especially helpful for evaluation of radiographs and complex wounds of the hand and face. The solution proved to be very valuable for both attending physicians and residents in plastic surgery. The photographs provide rich detail and resolution comparable to high-quality prints. The mechanics of obtaining images and the process of sending them electronically was readily mastered. Images reached their destination in only a few minutes over standard telephone lines. No problems were encountered while sending or viewing images on Macintosh or Windows platforms. Determining course of action with a complete clinical history now includes a level of visual detail previously not available. As this application expands into wider use, data integrity and safety will have to be more formally secured and monitored. Our model of telemedicine has broad

  20. The Connection between Worship Attendance and Racial Segregation Attitudes among White and Black Americans

    R. Khari Brown

    2011-07-01

    Full Text Available The present study finds that, for Whites, worship attendance is associated with heightened support for racial segregation. This has much to do with the fact that the individuals that attend worship service the least, secular and young adults, tend to be more racially progressive. That is, the extent to which secular and Generation X and Y individuals attend worship services as often as others, worship attendance is associated with weakened opposition to racial segregation. Conversely, worship attendance, religious affiliation, and age cohort are largely unrelated to Black racial segregation attitudes.

  1. Factors associated with non-attendance, opportunistic attendance and reminded attendance to cervical screening in an organized screening program: a cross-sectional study of 12,058 Norwegian women

    Eriksen Tormod

    2011-04-01

    Full Text Available Abstract Background Cervical cancer incidence and mortality may be reduced by organized screening. Participant compliance with the attendance recommendations of the screening program is necessary to achieve this. Knowledge about the predictors of compliance is needed in order to enhance screening attendance. Methods The Norwegian Co-ordinated Cervical Cancer Screening Program (NCCSP registers all cervix cytology diagnoses in Norway and individually reminds women who have no registered smear for the past three years to make an appointment for screening. In the present study, a questionnaire on lifestyle and health was administered to a random sample of Norwegian women. The response rate was 68%. To address the predictors of screening attendance for the 12,058 women aged 25-45 who were eligible for this study, individual questionnaire data was linked to the cytology registry of the NCCSP. We distinguished between non-attendees, opportunistic attendees and reminded attendees to screening for a period of four years. Predictors of non-attendance versus attendance and reminded versus opportunistic attendance were established by multivariate logistic regression. Results Women who attended screening were more likely than non-attendees to report that they were aware of the recommended screening interval, a history of sexually transmitted infections and a history of hormonal contraceptive and condom use. Attendance was also positively associated with being married/cohabiting, being a non-smoker and giving birth. Women who attended after being reminded were more likely than opportunistic attendees to be aware of cervical cancer and the recommended screening interval, but less likely to report a history of sexually transmitted infections and hormonal contraceptive use. Moreover, the likelihood of reminded attendance increased with age. Educational level did not significantly affect the women's attendance status in the fully adjusted models. Conclusions The

  2. Postpartum Visit Attendance Increases the Use of Modern Contraceptives

    Saba W. Masho

    2016-01-01

    Full Text Available Background. Delays in postpartum contraceptive use may increase risk for unintended or rapid repeat pregnancies. The postpartum care visit (PPCV is a good opportunity for women to discuss family planning options with their health care providers. This study examined the association between PPCV attendance and modern contraceptive use using data from a managed care organization. Methods. Claims and demographic and administrative data came from a nonprofit managed care organization in Virginia (2008–2012. Information on the most recent delivery for mothers with singleton births was analyzed (N = 24,619. Routine PPCV (yes, no and modern contraceptive use were both dichotomized. Descriptive analyses provided percentages, frequencies, and means. Multiple logistic regression was conducted and ORs and 95% CIs were calculated. Results. More than half of the women did not attend their PPCV (50.8% and 86.9% had no modern contraceptive use. After controlling for the effects of confounders, women with PPCV were 50% more likely to use modern contraceptive methods than women with no PPCV (OR = 1.50, 95% CI = 1.31, 1.72. Conclusions. These findings highlight the importance of PPCV in improving modern contraceptive use and guide health care policy in the effort of reducing unintended pregnancy rates.

  4. Religious attendance after elevated depressive symptoms: is selection bias at work?

    Lloyd Balbuena

    2014-03-01

    Full Text Available In an attempt to determine if selection bias could be a reason that religious attendance and depression are related, the predictive value of elevated depressive symptoms for a decrease in future attendance at religious services was examined in a longitudinal panel of 1,673 Dutch adults. Religious attendance was assessed yearly over five years using the single question, “how often do you attend religious gatherings nowadays?” Depressive symptoms were assessed four times within the first year using the Depression subscale of the Brief Symptom Inventory. Logistic regression models of change in attendance were created, stratifying by baseline attendance status. Attenders who developed elevated symptoms were less likely to subsequently decrease their attendance (relative risk ratio: 0.55, 95% CI [0.38–0.79] relative to baseline as compared to those without elevated symptoms. This inverse association remained significant after controlling for health and demographic covariates, and when using multiply imputed data to account for attrition. Non-attenders were unlikely to start attending after elevated depressive symptoms. This study provides counter evidence against previous findings that church attenders are a self-selected healthier group.

  5. Reporting of exercise attendance rates for people with chronic obstructive pulmonary disease: a systematic review.

    Williams, Marie T; Lewis, Lucy K; McKeough, Zoe; Holland, Anne E; Lee, Annemarie; McNamara, Renae; Phillips, Anna; Wiles, Louise; Knapman, Leona; Wootton, Sally; Milross, Maree; Effing, Tanja

    2014-01-01

    While recommendations for the duration, frequency, mode and intensity of exercise programmes for people with chronic obstructive pulmonary disease (COPD) are specified in consensus statements, criteria for exercise session attendance are less clear. The review questions were: (i) how commonly are a priori criteria and attendance rates reported for people with COPD participating in exercise programmes and (ii) what is the strength of association between attendance and improvements in functional exercise capacity. Database searches identified primary studies of people with COPD participating in exercise or pulmonary rehabilitation programmes of at least 2 weeks duration. Primary outcomes were a priori criteria for attendance, reports of attendance at supervised exercise sessions and mean improvements in functional exercise assessments. Data extraction processes were confirmed prospectively (>80% agreement). Variants of exercise attendance data were described. Linear associations between attendance and improvements in exercise outcomes were explored (Pearson r, P exercise data before and after the intervention, there was little to no relationship between improvements in functional exercise capacity and training volume (prescribed r = -0.03, P = 0.88; attended r = -0.24, P = 0.18). Reporting of exercise programme attendance rates is low and of variable quality for people with COPD. Consistent and explicit reporting of exercise attendance in people with COPD will enable calculation of dose-response relationships and determine the value of a priori exercise attendance criteria.

  6. The Effect of Men's Body Attitudes and Motivation for Gym Attendance.

    Caudwell, Kim M; Keatley, David A

    2016-09-01

    Caudwell, KM and Keatley, DA. The effect of men's body attitudes and motivation for gym attendance. J Strength Cond Res 30(9): 2550-2556, 2016-The current study integrates men's body attitudes with implicitly and explicitly measured motivation to investigate the role of these factors in predicting gym attendance. Male participants (N = 99) who regularly attended a gym were recruited to participate in an online questionnaire. Participants completed implicit and explicit measures of motivation, explicitly measured men's body attitudes, and reported the average number of gym visits per week. Attitudes related to body fat and explicitly measured autonomous motivation significantly predicted typical gym attendance. Implicitly measured motivation significantly and negatively predicted gym attendance. Results indicate some support for a dual-systems account of gym attendance. Men's body attitudes and autonomous motivation influences gym attendance; however, implicitly measured motivation showed antagonistic effects. Although individuals may explicitly state their autonomous motivation for gym attendance, attendance may also be influenced at the explicit level. Health and fitness professionals may improve gym attendance by focusing on people's reasons for attending a gym, facilitating autonomous motivation in clients, and minimizing the influence of controlled reasons for exercise.

  7. Did the elimination of lead from petrol reduce crime in the USA in the 1990s? [v2; ref status: indexed, http://f1000r.es/220

    Wayne Hall

    2013-10-01

    Full Text Available This article assesses the evidence for the hypothesis that a decline in all types of crime since the early 1990s in the USA was a consequence of removing lead from petrol between 1975 and 1985. It describes ecological and econometric studies that have generally but not always found correlations between lead exposures in childhood and some types of crime 20 years later; a small number of epidemiological studies that have found a dose-response relationship between lead exposure in childhood and self-reported and officially recorded criminal offences in young adulthood; and evidence for the biological plausibility of a causal relationship. Lead exposure in childhood may have played a small role in rising and falling crime rates in the USA but it is unlikely to account for the very high percentage of the decline suggested by the ecological studies. The major anomaly in the evidence is that the associations reported in ecological studies are much stronger (explaining 56-90% of the variation in crime rates than the weaker relationships found in the cohort studies (that typically explain less than 1% of the variance in offending.  Suggestions are made for research that will better assess the contribution that reduced lead exposure has made to declining crime rates in the USA.

  17. Package power stations for export

    1985-01-01

    The cheap and efficient generation of power is an essential requirement for the success and prosperity of any community and is especially important to third world countries. It is therefore logical that the more technologically advanced nations should seek to produce power stations for the developing countries. Power plant can now be designed into a packaged form that may be readily exported and commissioned. This valuable and interesting collection of papers were originally presented at a seminar organised by the Power Industries Division of the Institution of Mechanical Engineers. Topics considered include the developing world market for packaged power stations using indigenous fuels; multi-fuel systems for power generation; packaging, modularisation, and containerisation of equipment for power boilers for export; compact coal-fired industrial plant; rural woodburning power stations; biomass gasification based power generation technology and potential; gas fed reciprocating engine development; packaged heavy duty gas turbines for power generation; and criteria for assessing the appropriateness of package power technologies in developing countries.

    The use of automation systems will be approached as fundamental tool in the control of sales in the pumps as well electronic management of stock in the tanks on a consolidated and integrated way, offering reliability and total control in the administration of fuel resale, no matter if the user be a one station owner, a group of dozens stations, or oil companies in general. These systems allow the local control in the gas station as well remotely through internet access or other kind of communication interface which be Also available. We will give some examples, as the possibility of remote stock management through a communication link between the oil company and gas station, in order to setup in the system a minimum stock level in each tank, that when being reached sends an automatic alarm for the oil company and another alarm for the station operator, so that the replenishment is programmed immediately without the need of sending purchase order by fax, e mail or telephone. This process brings a huge reduction of costs in the delivery logistics as well in the operational costs, reverting directly on a growth of the gas station and dealer's profit. Through this control, is also possible the remote management of fuel leak alarms in attendance to CONAMA 273, making possible a shared control and offering higher safety for both parts involved, considering the concept of environmental co-responsibility between gas station and oil company (dealer).

  7. Long-term patterns of dental attendance and caries experience among British adults: a retrospective analysis.

    Aldossary, Arwa; Harrison, Victoria E; Bernabé, Eduardo

    2015-02-01

    There is inconclusive evidence on the value of regular dental attendance. This study explored the relationship between long-term patterns of dental attendance and caries experience. We used retrospective data from 3,235 adults, ≥ 16 yrs of age, who participated in the Adult Dental Health Survey in the UK. Participants were classified into four groups (always, current, former, and never regular-attenders) based on their responses to three questions on lifetime dental-attendance patterns. The association between dental-attendance patterns and caries experience, as measured using the decayed, missing, or filled teeth (DMFT) index, was tested in negative binomial regression models, adjusting for demographic (sex, age, and country of residence) and socio-economic (educational attainment, household income, and social class) factors. A consistent pattern of association between long-term dental attendance and caries experience was found in adjusted models. Former and never regular-attenders had a significantly higher DMFT score and numbers of decayed and missing teeth, but fewer filled teeth, than always regular-attenders. No differences in DMFT or its components were found between current and always regular-attenders. The findings of this study show that adults with different lifetime trajectories of dental attendance had different dental statuses.

  8. Why do students miss lectures? A study of lecture attendance amongst students of health science.

    Bati, A Hilal; Mandiracioglu, Aliye; Orgun, Fatma; Govsa, Figen

    2013-06-01

    In the domain of health sciences, attendance by students at lectures is more critical. Lecture attendance is an issue which has been widely neglected. This study aims to determine those factors which affect the lecture attendance. The research data was collected by means of a questionnaire during the second semester of the academic year 2010-2011 from second-year students of the Faculties of Medicine, Pharmacy, Dentistry and Nursing. Together with demographic data, the questionnaire includes a Likert-type scale aiming to determine the factors influencing attendance at lectures. 663 participated in this study on a voluntary basis from Medical, Dentistry, Pharmacy and Nursing Faculties. Raising attainment levels, being able to take their own lecture notes, learning which aspects of the lecture content were being emphasized, and the opportunity to ask questions were amongst the chief reasons for attending lectures. It appears that the factors preventing students from attending lectures are mainly individual. Amongst the most frequently cited causes of non-attendance, sleeplessness, ill health and the inefficiency of lectures in overcrowded halls are emphasized. In the totals and sub-dimensions of the Lecture Attendance Scale, Medical Faculty students have average scores higher than those of students at other faculties. The vital nature of professional expertise and its applications, health sciences students' attendance at lectures carries greater importance. It is important to strengthen the mentoring system with regard to individual and external factors, which have been implicated as having a substantial influence on lecture attendance by students.

    C. Ntoane

    1988-09-01

    Full Text Available A survey was conducted among the 104 traditional birth attendants (hommaabotsetse in Bophuthatswana during the 1985 winter vacation. The objective of the survey was to estimate the number of women practising as well as provide their characteristics and practices. Findings revealed that bommaabotsetse were elderly women with an average age of 58 years, were married and had a considerable period of experience. Preference for delivery in a health service, which is not always accessible, is discussed with a suggestion of a few options. It is concluded that some women in rural Bophuthatswana make a conscious choice of home delivery even when modern delivery facilities are available. A training programme for bommaabotsetse with adequate support and supervision is recommended.

  12. Learning where to Attend with Deep Architectures for Image Tracking

    Denil, Misha; Larochelle, Hugo; de Freitas, Nando

    2011-01-01

    We discuss an attentional model for simultaneous object tracking and recognition that is driven by gaze data. Motivated by theories of perception, the model consists of two interacting pathways: identity and control, intended to mirror the what and where pathways in neuroscience models. The identity pathway models object appearance and performs classification using deep (factored)-Restricted Boltzmann Machines. At each point in time the observations consist of foveated images, with decaying resolution toward the periphery of the gaze. The control pathway models the location, orientation, scale and speed of the attended object. The posterior distribution of these states is estimated with particle filtering. Deeper in the control pathway, we encounter an attentional mechanism that learns to select gazes so as to minimize tracking uncertainty. Unlike in our previous work, we introduce gaze selection strategies which operate in the presence of partial information and on a continuous action space. We show that a s...

  15. Mismatch negativity during attend and ignore conditions in Alzheimer's disease.

    Kazmerski, V A; Friedman, D; Ritter, W

    1997-09-01

    Mismatch negativities (MMNs) of the event-related potential to deviant tones and environmental sounds were recorded during active and ignore oddball sequences in young and elderly controls and patients with probable Alzheimer's disease (PAD). MMNs were smaller in the PAD waveforms compared to those of the controls, suggesting a degraded sensory memory trace in these subjects; however, under ignore conditions, environmental sounds elicited robust MMNs in the PAD group along with N2b and novelty P3 components in similar fashion to controls. As N2b and P3 are usually elicited by attended stimuli, these data suggest that in the PAD subjects, the highly deviant events involuntarily captured attention, perhaps reflecting the activation of an attentional switching mechanism. Because this passive switching is thought to reflect activation of a mechanism located in the frontal lobes, the data suggest that this putative frontal lobe mechanism is relatively intact in the early stages of the disease.

  16. Word-identification priming for ignored and attended words

    Stone, M.; Ladd, S. L.; Vaidya, C. J.; Gabrieli, J. D.

    1998-01-01

    Three experiments examined contributions of study phase awareness of word identity to subsequent word-identification priming by manipulating visual attention to words at study. In Experiment 1, word-identification priming was reduced for ignored relative to attended words, even though ignored words were identified sufficiently to produce negative priming in the study phase. Word-identification priming was also reduced after color naming relative to emotional valence rating (Experiment 2) or word reading (Experiment 3), even though an effect of emotional valence upon color naming (Experiment 2) indicated that words were identified at study. Thus, word-identification priming was reduced even when word identification occurred at study. Word-identification priming may depend on awareness of word identity at the time of study.

    2017-01-01

    Background and purpose Depressive symptoms are common post-stroke. We examined stroke deficits and lifestyle factors that are independent predictors for depressive symptomology. Methods A retrospective chart review was performed for patients' post-stroke who attended outpatient clinics at a hospital in Southwestern Ontario between 1 January 2014 and 30 September 2014. Demographic variables, stroke deficits, secondary stroke risk factors and disability study measures [Patient Health Questionnaire-9 (PHQ-9) and Montreal Cognitive Assessment (MoCA)] were analyzed. Results Of the 221 outpatients who attended the stroke clinics (53% male; mean age = 65.2 ± 14.9 years; mean time post-stroke 14.6 ± 20.1 months), 202 patients were used in the final analysis. About 36% of patients (mean = 5.17 ± 5.96) reported mild to severe depressive symptoms (PHQ-9 ≥ 5). Cognitive impairment (CI), smoking, pain and therapy enrollment (p depressive symptoms. Patients reporting CI were 4 times more likely to score highly on the PHQ-9 than those who did not report CI (OR = 4.72). While controlling for age, MoCA scores negatively related to depressive symptoms with higher PHQ-9 scores associated with lower MoCA scores (r= -0.39, p depressive symptoms are common in the chronic phase post-stroke and were partially related to cognition, pain, therapy enrollment and lifestyle factors. Implications for Rehabilitation Stroke patients who report cognitive deficits, pain, tobacco use or being enrolled in therapy may experience increased depressive symptoms. A holistic perspective of disease and lifestyle factors should be considered while assessing risk of depressive symptoms in stroke patients. Patients at risk for depressive symptoms should be monitored at subsequent outpatient visits.

    Full Text Available OBJECTIVE: to identify the dietary patterns of adolescents attending public municipal schools in Northern Minas Gerais, Brazil, and to test the association between these patterns and socioeconomic variables and nutritional status of the adolescents. METHODS: this was an analytical, cross-sectional study with randomized sample of 474 adolescents of both genders, between 11 and 17 years of age, attending municipal public schools in the urban area of Montes Claros, MG, Brazil. The parents provided demographic and economic data. The nutritional status (body mass index - BMI of the adolescents was determined at school, and their dietary habits were assessed though the administration of the Food Frequency Questionnaire for Adolescents (FFQA. Based on 26 categories extracted from FFQA, dietary patterns were determined using principal component analysis (PCA and associated to anthropometric and socioeconomic factors using multiple regression analysis. RESULTS: the three dietary patterns identified, "junk food," "healthy," and "traditional", explained 23.26%, 6.90%, and 5.24% of data variability, respectively. Adolescents with per capita family income exceeding half a minimum wage were more likely to consume the "junk food" pattern (OR = 1.66; 95% CI = 1.07-2.56, and overweight adolescents had lower chances of eating the "healthy" food pattern (OR = 0.56, 95% CI = 0.35-0.91. CONCLUSIONS: deviations from the "healthy" patterns were not associated to low income, but rather to bad eating habits in the studied population. Overweight adolescents did not adhere to the "healthy" dietary pattern, emphasizing the need for nutritional education among them.

  1. Discontinued dental attendance among elderly people in Sweden

    Grönbeck-Linden, Ingela; Hägglin, Catharina; Petersson, Anita; Linander, Per O.; Gahnberg, Lars

    2016-01-01

    Aim: Our objective was to study the loss of dental attendance and a possible age trend among patients aged ≥65 years in Sweden. Regular dental check-ups are considered to be an important factor in maintaining oral health. Approximately 80% of the adult population in Sweden are enrolled in a regular check-up system; however, dental practitioners often find that older patients attend fewer check-ups. Old people may naturally lose contact with dental services as they move to special housing or die. In this systematic study, these factors were investigated and used as exclusion criteria. Materials and Methods: Data were collected for all patients (n = 4759) aged 65 or older from the electronic journal system in 3 large public dental clinics in 3 communities. Their dental records for the years 2004–2009 were studied longitudinally by 1 person at each clinic; 1111 patients were excluded (patients died during study period, wanted emergency care only, obtained special dental care allowance, moved from the community or moved to special housing, or left the clinic for another caregiver). The statistical analyses were performed using the Statistical Package for the Social Sciences version 21 (IBM). Results: Of the 3648 patients (1690 men and 1958 women) included in the study, 13% lost contact with their dental service over the course of the study (10% of those were aged 65–79 and 21% ≥80). The decrease in regular dental contact had a statistically significant association with increasing age (P < 0.001). Conclusion: A considerable number of older people living independently or with moderate supportive care in their own homes lost contact with dental service despite enrolment in a recall system.

  7. Environmental interactions on Space Station

    Garrett, Henry B.; Gabriel, Stephen B.; Murphy, Gerald B.

    1990-01-01

    This paper describes the key environment/system interactions associated with the Space Station and its companion polar platform and defines the range of test environments that will need to be simulated. These environments include the neutral atmosphere, the ionospheric plasma, natural and man-made particulates, the ambient magnetic field, the South Atlantic Anomaly, and the ram/wake environment. The system/environment interactions include glow, oxygen erosion, drag, radiation effects, induced electric fields, high-voltage solar-array effects, and EMC/EMI associated with plasma/neutral gas operations. The Space Station and its associated systems pose unique demands on the ability to simulate these effects; synergistic effects require multiple environments to be simulated simultaneously, and the long life requirements require proper scaling of the exposure time. The analysis of specific effects and the calibration or improvement of ground test techniques will likely require in situ evaluation. Qualification and acceptance testing, because of cost and the impractically of extensive on-orbit analysis/modification, will likely remain ground test objectives except in very rare cases.

  8. Space station operating system study

    Horn, Albert E.; Harwell, Morris C.

    1988-01-01

    The current phase of the Space Station Operating System study is based on the analysis, evaluation, and comparison of the operating systems implemented on the computer systems and workstations in the software development laboratory. Primary emphasis has been placed on the DEC MicroVMS operating system as implemented on the MicroVax II computer, with comparative analysis of the SUN UNIX system on the SUN 3/260 workstation computer, and to a limited extent, the IBM PC/AT microcomputer running PC-DOS. Some benchmark development and testing was also done for the Motorola MC68010 (VM03 system) before the system was taken from the laboratory. These systems were studied with the objective of determining their capability to support Space Station software development requirements, specifically for multi-tasking and real-time applications. The methodology utilized consisted of development, execution, and analysis of benchmark programs and test software, and the experimentation and analysis of specific features of the system or compilers in the study.

  9. Smos Land Product Validation Activities at the Valencia Anchor Station

    Lopez-Baeza, Ernesto

    ABSTRACT Soil moisture is a key parameter controlling the exchanges between the land surface and the atmosphere. In spite of being important for weather and climate modeling, this parameter is not well observed at a global scale. The SMOS (Soil Moisture and Ocean Salinity) Mission was designed by the European Space Agency (ESA) to measure soil moisture over continental surfaces as well as surface salinity over the oceans. Since 2001, the Valencia Anchor Station is currently being prepared for the validation of SMOS land products, namely soil moisture content and vegetation water content. The site has recently been selected by the Mission as a core validation site, mainly due to the reasonable homogeneous characteristics of the area which make it appropriate to undertake the validation of SMOS Level 2 land products during the Mission Commissioning Phase, before attempting more complex areas. Close to SMOS launch, ESA has defined and designed a SMOS V alidation Rehearsal C ampaign P lan which purpose is to repeat the Commissioning Phase execution with all centers, all tools, all participants, all structures, all data available, assuming all tools and structures are ready and trying to produce as close as possible the post-launch conditions. The aim is to test the readiness, the ensemble coordination and the speed of operations, and to avoid as far as possible any unexpected deficiencies of the plan and procedure during the real C ommissioning P hase campaigns. For the rehearsal activity, a control area of 10 x 10 km2 has been chosen at the Valencia Anchor Station study area where a network of ground soil moisture measuring stations is being set up based on the definition of homogeneous physio-hydrological units, attending to climatic, soil type, lithology, geology, elevation, slope and vegetation cover conditions. These stations are linked via a wireless communication system to a master post accessible via internet. The ground soil moisture stations will also be used

    This is the final version of the article. It first appeared from Wilson Ornithological Society via http://dx.doi.org/10.1676/09-156.1 We quantified resident and migrant bird attendance at army ant swarm raids (n  =  48) in a neotropical montane forest. All observations were during seasons when Nearctic migrant birds are present. Bird species differed in army ant raid-attending behavior. Resident bird species attended 2 to 54% of raids, while migrants attended at lower maximum frequencies (...

  13. Reduction of vaporous emissions during transport of petrol and mineral oil products by river tank ships (20. BImSchV); Verminderung gasfoermiger Emissionen beim Transport von Ottokraftstoffen und Mineraloelprodukten mit Binnenschiffen (20. BImSchV)

    The gas-free ventilation of the tanks of river tank ships by the common praxis to ventilate the tank atmosphere into ambient air is a big emission source of VOCs and a strong deterioration of air quality. It was shown during several measurement campaigns that the ventilation of the tank atmosphere of river tank ships via the loading / unloading pipes into the land-site vapour recovery unit is a technical solution. The measured emission source strengths during this type of ventilation are of the same amount as the measured emission source strengths during loading and unloading of petrol and are caused by attachment and detachment of loading / unloading pipes only. Furthermore, the concentrations of petrol in the tank atmosphere were measured by the PTB during these experiments. As result of the investigations a leaflet as instruction of environment friendly ventilation of tank atmosphere of river tank ships for the inland sailors and operators of tank storage plants was composed. On the basis of an inquiry of the available vapour recovery units the required capacity of land-site vapour recovery units for the replacement of all ventilation of tank atmosphere to open air was estimated. The capacity of the available vapour recovery units is too low for a preferably short time period of tank atmosphere ventilation. Solving this problem not only the enhancement of the capacity of the available vapour recovery units up to a capacity of 2,200 m{sup 3}/h must be considered but their availability at loading / unloading points of petrol as well as the availability of berthing place must be taken into account also. The necessary enhancement of the capacity and the number of possible new installations of vapour recovery units cannot be defined now because a new amendment for the execution of the 20. BImSchV came into force on 25 August 2001 which allows the ventilation of tank atmosphere of river tank ships to open air under certain conditions until 31 December 2005. To draw

    2013-04-01

    The Struve Geodetic Arc was developed in Years 1816 to 1855, 200 years ago. Historic information on the points of the Struve Geodetic Arc are included in the UNESCO World Heritage list in 2005. Nevertheless, the sites of many points are still not identified nor included in the data bases nowadays. Originally STRUVE arc consisted of 258 main triangles with 265 triangulation points. Currently 34 of the original station points are identified and included in the in the UNESCO World Heritage list. identified original measurement points of the Meridian Arc are located in Sweden (7 points), Norway (15), Finland (83), Russia (1), Estonia (22), Latvia (16), Lithuania (18), Belorussia (28), Ukraine (59) and Moldova (27). In Year 2002 was initiated another large coverage project - European Position Determination System "EUPOS®". Currently there are about 400 continuously operating GNSS (Global Navigation Satellite Systems) stations covering EU countries Estonia, Latvia, Lithuania, Poland, Czech Republic, Slovakia, Hungary, Bulgaria, Romania and East European countries Ukraine and Moldavia. EUPOS® network is a ground based GNSS augmentation system widely used for geodesy, land surveying, geophysics and navigation. It gives the opportunity for fast and accurate position determination never available before. It is an honorable task to use the EUPOS® system for research of the Struve triangulation former sites. Projects with Struve arc can popularize geodesy, geo-information and its meaning in nowadays GIS and GNSS systems. Struve Arc and its points is unique cooperation cross-border object which deserve special attention because of their natural beauty and historical value for mankind. GNSS in geodesy discovers a powerful tool for the verification and validation of the height values of geodetic leveling benchmarks established historically almost 200 years ago. The differential GNSS and RTK methods appear very useful to identify vertical displacement of landscape by means of

  16. Pathways of decision making among Yucatan Mayan traditional birth attendants.

    Anderson, Barbara A; Anderson, E N; Franklin, Tracy; Dzib-Xihum de Cen, Aurora

    2004-01-01

    In rural, developing world communities, women are often isolated from biomedical services. Frequently, traditional birth attendants (TBAs) are the only caregivers during childbirth, both normal and complicated. Women trust their TBAs to manage their births. Globally, government and non-governmental organizations (NGOs) have sought to upgrade TBAs' skills and to encourage them to refer complications. However, most training programs have failed to change TBAs' practice substantially. Logistical barriers in reaching biomedical services in a timely manner are a key issue. Another is the difference between biomedical and traditional practitioners in the cognitive frameworks that shape decision making and management behaviors. The purpose of this study, conducted in Quintana Roo State, Mexico, was to listen to the voices of practicing Yucatec Maya TBAs (parteras) as they described decision making and management of complicated births. In-depth interviews with six practicing parteras in rural, isolated communities revealed that the parteras used traditional Maya ethnomedicine while valuing biomedical approaches. We isolated themes in decision making and mapped management of birth complications. Integrating TBAs' traditional knowledge into biomedical training programs is one way to honor their knowledge and make training relevant.

  17. Identifying the training needs of traditional birth attendants.

    Salako, A A; Daniel, O J

    2007-01-01

    With the aid of pre-tested, structured, interview questionnaires, 51 traditional birth attendants (TBAs), identified by their certificate of traditional midwifery, were assessed for their knowledge about the care given in pregnancy, labour, and the postnatal period, beliefs and delivery practices including child care, and their attitude towards orthodox midwifery. A total of 22 (43.1%) so identified were found to be practicing traditional midwifery as a full-time job, while 29 (56.9%) were practising on a part-time basis, doing other jobs such as farming and trading. Twenty-two (51.2%) of the male TBAs practised traditional midwifery as a full-time job, while the remaining 21 (48.8%) practised traditional midwifery part-time, along with farming occupation. All the female TBAs practised traditional midwifery part-time with their main occupation such as trading. There was no significant difference between the mean age of male compared with female respondents (59.3+/-15.1 vs. 54.6+/-15.9 years; P = 0.43). Harmful traditional practices, practices that may need verification and areas where training is needed are highlighted. The importance of registration and active supervision of their practices were discussed. The skills that need to be stressed include identification of danger signs in pregnancy and prompt referral of maternal complications. The essence of registration for monitoring of their activities cannot be overemphasized. Findings also revealed that appropriate training could expand their roles in primary health care programmes.

  18. Public Staff Meetings – thank you for a large attendance

    Staff Association

    2013-01-01

    The public meetings of the Staff Association which took place recently were attended by about 500 staff, a large fraction of them young and on a limited duration (LD) contract. The audience mainly shared the worries of the Staff Association concerning the low number of IC post openings in this and the coming years. Moreover, after the meeting several LD contract holders contacted the Staff Association to express their point of view and to put forward their ideas to tackle this problem. As explained in those meetings, the Staff Association emphasizes that personnel policy should not be guided by self-imposed quota, even under pressure by the Member States. As we have repeated several times, CERN needs a total staff complement well beyond the baseline ceiling of 2250, the number agreed by Council, if it has to guarantee an efficient and excellence level of service to the ever-growing user community, which has almost doubled over the last decade. Moreover, the indefinite contract (IC) component should stan...

  19. Traditional Birth Attendants and Policy Ambivalence in Zimbabwe

    Naume Zorodzai Choguya

    2014-01-01

    Full Text Available This paper analyses the importance of the services rendered by traditional birth attendants (TBAs to pregnant women in Zimbabwe. It argues that, though an integral part of the health system, the ambivalence in terms of policy on the part of the government leaves them in a predicament. Sociocultural values as well as tradition imbue TBAs power and authority to manage pregnancies and assist in child deliveries. On the other hand, government policies expounded through the Ministry of Health (MoH programs and policies appear to be relegating them to the fringes of healthcare provision. However, in a country with a failing health system characterized by mass exodus of qualified personnel, availability of drugs, and understaffing of healthcare centres, among others, TBAs remain the lifeline for many women in the country. Instead of sidelining them in healthcare interventions, I argue that their integration, however, problematic and often noted to be with disastrous consequences for traditional medicine, presents the sole viable solution towards achieving MDGs 4 and 5. The government and MoH should capitalize on the availability of and standing working relations of TBAs with the grassroots for better/positive maternal health outcomes. In a country reeling with high maternal deaths, TBAs’ status and position in society make them the best intervention tools.

    2016-01-01

    Human behaviour is context-dependent—based on predictions and influenced by the environment and other people. We live in a dynamic world where both the social stimuli and their context are constantly changing. Similar dynamic, natural stimuli should, in the future, be increasingly used to study social brain functions, with parallel development of appropriate signal-analysis methods. Understanding dynamic neural processes also requires accurate time-sensitive characterization of the behaviour. To go beyond the traditional stimulus–response approaches, brain activity should be recorded simultaneously from two interacting subjects to reveal why human social interaction is critically different from just reacting to each other. This theme issue on Attending to and neglecting people contains original work and review papers on person perception and social interaction. The articles cover research from neuroscience, psychology, robotics, animal interaction research and microsociology. Some of the papers are co-authored by scientists who presented their own, independent views in the recent Attention and Performance XXVI conference but were brave enough to join forces with a colleague having a different background and views. In the future, information needs to converge across disciplines to provide us a more holistic view of human behaviour, its interactive nature, as well as the temporal dynamics of our social world.

  2. Relational Inquiry—Attending to the Spirit of Nursing Students

    Michelle Spadoni

    2016-03-01

    Full Text Available The impetus for this paper came from our experiences as learner-teachers of re-considering the epistemological and ontological roots of our undergraduate-nursing curriculum. It began as an earnest dialogue regarding particular aspects of first year undergraduate-nursing theory content, specifically, caring and compassion, self-concept and nursing identity, spirituality and culture, a simple question—how could we better engage first year nursing students with what they frequently considered to be “abstract” and “soft” concepts? An organic need to be “good teachers” and introduce learners to fundamental concepts in nursing, and have them understand, in meaningful ways, the complexity of “caring and compassion” with respect to what it is that nurses do, think, and enact. To this end, we enlisted Relational Inquiry, as articulated by Gweneth Hartrick Doane and Colleen Varcoe, as a means of creating an epistemological and ontological foundation for our teaching practice in order to better support the development of critically reflective, community orientated, caring relational practitioners. Initially, we thought relational inquiry was an epistemological endeavor and found that it is an ontological undertaking. We discovered that practicing from a relational caring perspective shifted our focus from the content to the student as a developing practitioner and human being. Through the process of re-imagining our teaching practice, we have begun to re-consider the importance of “attending to the spirit” of nursing students.

    Full Text Available Radio Frequency Identification (RFID initially is of great use in the marketing field render billing easy. It came into effect since world war-II attained its wide spread recognition only when Walmart introduced it as ‘mandate’. An object within the range of 20 feet can be easily tracked with the aid of its unique barcode using RFID chip. It is sophisticated than the primitive barcode techniques as there is no need of positioning of the scanner. Cloud computing is a system which provides access to all soft ware’s without installation, for a desired time period, at a specific cost, only with the help of a single web browser.. Interfacing RFID with cloud computing would be more beneficiary in solving current issues. Technological updates can be done without any technical support. This paper presents theoverview of interfacing RFID with cloud computing for updating students’ attendance and updating it into the parents’ corner and faculty mails. By considering the present issue, providing unique RFID code to the students reduce malpractice and human error. Also Human resources can be saved by the application of cloud computing. Time management is the most effective advantage gained from the use ofRFID and cloud computing.

  7. ACSSB land mobile earth station

    Taira, Shinichi; Ikegami, Tetsushi; Suzuki, Ryutaro; Suzuki, Shoichi; Kawahara, Hideki; Tada, Shun-Ichi

    1990-03-01

    This paper describes the performance of the land mobile earth station using the Amplitude Companded Single Sideband (ACSSB) modulation technique developed for mobile satellite communications and results of the field experiments which were conducted in rural, suburban, and urban areas. This ACSSB system uses a 3-kHz pilot tone, and the voice frequency band is from 300 to 2500 Hz. The experiments show that the required C/N0 for voice communications is 40 dBHz and the required C/N0 for pilot signal tracking is 34 dBHz. Voice quality in rural and suburban areas was degraded slightly. In urban areas shadowings due to the presence of large buildings and trees caused signal losses. A comparison of the ACSSB system with the conventional narrow-band frequency-modulation system indicates that the ACSSB system can transmit voice signals more efficiently.

  10. Evaluation of environmental levels of aromatic hydrocarbons in gasoline service stations by gas chromatography.

    Periago, J F; Zambudio, A; Prado, C

    1997-08-22

    The volume of gasoline sold in refuelling operations and the ambient temperature, can increase significantly the environmental levels of aromatic hydrocarbon vapours and subsequently, the occupational risk of gasoline service station attendants, specially in the case of benzene. We have evaluated the occupational exposure to aromatic hydrocarbons by means of personal-breathing-zone samples of gasoline vapours in a service station attendant population. This evaluation was carried out using diffusive samplers, in two periods at quite different temperatures (March and July). A significant relationship between the volume of gasoline sold during the shift and the ambient concentration of benzene, toluene, and xylenes was found for each worker sampled. Furthermore a significant difference was found between the time-weighted average concentration of aromatic compounds measured in March, with ambient temperatures of 14-15 degrees C and July, with temperatures of 28-30 degrees C. In addition, 20% of the population sampled in the last period were exposed to a time-weighted average concentration of benzene above the proposed Threshold Limit Value of 960 micrograms/m(3) of the American Conference of Governmental Industrial Hygienists (ACGIH).

    Gusman, Christine Ranier; Viana, Ana Paula de Andrade Lima; Miranda, Margarida Araújo Barbosa; Pedrosa, Mayane Vilela; Villela, Wilza Vieira

    2015-05-01

    The present article describes an experience with traditional birth attendants carried out in the state of Tocantins, Brazil, between 2010 and 2014. The experience was part of a diagnostic project to survey home deliveries in the state of Tocantins and set up a registry of traditional birth attendants for the Health Ministry's Working with Traditional Birth Attendants Program (PTPT). The project aimed to articulate the home deliveries performed by traditional birth attendants to the local health care systems (SUS). Sixty-seven active traditional birth attendants were identified in the state of Tocantins, and 41 (39 indigenous) participated in workshops. During these workshops, they discussed their realities, difficulties, and solutions in the context of daily adversities. Birth attendants were also trained in the use of biomedical tools and neonatal resuscitation. Based on these experiences, the question came up regarding the true effectiveness of the strategy to include traditional birth attendants in the SUS. The present article discusses this theme with support from the relevant literature. The dearth of systematic studies focusing on the impact of PTPT actions on the routine of traditional birth attendants, including perinatal outcomes and remodeling of health practices in rural, riverfront, former slave, forest, and indigenous communities, translates into a major gap in terms of the knowledge regarding the effectiveness of such initiatives.

  1. Neurophysiological signals of ignoring and attending are separable and related to performance during sustained intersensory attention.

    Lenartowicz, Agatha; Simpson, Gregory V; Haber, Catherine M; Cohen, Mark S

    2014-09-01

    The ability to attend to an input selectively while ignoring distracting sensations is thought to depend on the coordination of two processes: enhancement of target signals and attenuation of distractor signals. This implies that attending and ignoring may be dissociable neural processes and that they make separable contributions to behavioral outcomes of attention. In this study, we tested these hypotheses in the context of sustained attention by measuring neurophysiological responses to attended and ignored stimuli in a noncued, continuous, audiovisual selective attention task. We compared these against responses during a passive control to quantify effects of attending and ignoring separately. In both sensory modalities, responses to ignored stimuli were attenuated relative to a passive control, whereas responses to attended stimuli were enhanced. The scalp topographies and brain activations of these modulatory effects were consistent with the sensory regions that process each modality. They also included parietal and prefrontal activations that suggest these effects arise from interactions between top-down and sensory cortices. Most importantly, we found that both attending and ignoring processes contributed to task accuracy and that these effects were not correlated--suggesting unique neural trajectories. This conclusion was supported by the novel observation that attending and ignoring differed in timing and in active cortical regions. The data provide direct evidence for the separable contributions of attending and ignoring to behavioral outcomes of attention control during sustained intersensory attention.

  5. Comparison of motor and cognitive performance of children attending public and private day care centers

    Mariana M. Santos

    2013-12-01

    Full Text Available BACKGROUND: Given that environmental factors, such as the school environment, can influence child development, more attention should be paid to the development of children attending day care centers. OBJECTIVE: Todetermine whether there are differences in the gross motor, fine motor, or cognitive performances of children between 1 and3 years-old of similar socioeconomic status attending public and private day care centers full time. METHOD: Participants were divided into 2 groups, 1 of children attending public day care centers (69 children and another of children attending private day care centers (47 children. All children were healthy and regularly attended day care full time for over 4 months. To assess cognitive, gross and fine motor performance, the Bayley Scales of Infant and Toddler Development III was used. The Mann-Whitney test was used for comparative analyses between groups of children between 13 and 24 months, 25 and 41 months, and 13 and 41 months. RESULTS: Children in public day care centers exhibited lower scores on the cognitive development scale beginning at 13 months old. The fine and gross motor performance scores were lower in children over the age of 25 months attending public centers. Maternal education was not related to the performance of children in either group. CONCLUSION: The scores of cognitive performance as well as fine and gross motor performance of children of similar socioeconomic status who attend public day care centers are lower than children attending private daycare centers.

  10. Relationships between breeding status, social -congregation attendance, and foraging distance of xantus's murrelets

    Hamilton, C.D.; Golightly, R.T.; Takekawa, J.Y.

    2011-01-01

    At night during the breeding season, Xantus's Murrelets (Synthliboramphus hypoleucus) congregate on the water adjacent to nesting colonies. We examined relationships of attendance at these nocturnal congregations, breeding status, and daytime foraging locations of radio-marked Xantus's Murrelets from Anacapa Island (33 in 2002, 44 in 2003) and Santa Barbara Island (35 in 2002) in the California Channel Islands. Murrelets thatspent more nights attending congregations were located closer to the island during the day, so regular attendance at the congregations may have constrained daytime traveling distances to foraging locations. In mid-May 2003 home-range sizes increased while congregation attendance decreased, likely indicating the end of colony attendance and declining availability of prey near Anacapa Island. In both years, incubating murrelets foraged farther from the colony than did nonbreeding murrelets, suggesting that breeding and nonbreeding murrelets use different foraging strategies to meet their energetic requirements.

  11. Do women requesting only contraception find attendance at an integrated sexual health clinic more stigmatizing than attendance at a family planning–only clinic?

    Sauer U

    2013-02-01

    Full Text Available Ulrike Sauer,1 Arti Singh,2 Punam Rubenstein,1 Rudiger Pittrof3 1Department of Reproductive and Sexual Health Services, Enfield Community Services, London, UK; 2University Health Services, KNUST Hospital, Kumasi, Ghana, 3Guy’s and St Thomas’ NHS Trust, London, UK Purpose: Both sexually transmitted infections and the genitourinary medicine clinics that patients attend for management of sexually transmitted infections are stigmatized by patients’ perceptions. The aim of this study was to assess whether women requesting contraception only find attendance at an integrated sexual health clinic (ISHC more stigmatizing than attendance at a family planning (FP–only clinic. Patients and methods: Women requesting contraception only were asked to complete a stigma assessment questionnaire in the waiting room of the clinic they attended. Ease of understanding was assessed for each item of the questionnaire prior to commencement of the survey. The questionnaire was given to women attending either an ISHC or a FP-only clinic. Results: One hundred questionnaires that fulfilled the inclusion criteria were returned. The users of FP-only services were generally older than the users of ISHCs and were more likely than the users of ISHCs to classify themselves as UK white. Stigma perception was significantly higher for the ISHC than the FP-only clinic. Conclusion: The results of this research indicate that among women who request contraception only, perceived stigma is higher when they attend an ISHC than when they attend a FP-only clinic. As this survey only enrolled clinic users, the authors were unable to assess whether integration generates sufficient stigma to deter some women from accessing contraception from integrated services. Of all stigma-related issues, disclosure concerns are likely to be the most important to the service user. Stigma is not an issue of overriding concern for most service users.

  4. Modeling passenger flows in public transport stations

    Cem Kırlangıçoğlu

    2015-06-01

    Full Text Available There are many architectural design parameters for public transport stations which include urban and station level studies. Each station must be designed in accordance with the basic passenger requirements such as accessibility, safety, comfort, satisfaction and etc. Circulation spaces must be formed and sized to meet the minimum movement needs of passengers. For an underground station; main entrance region, position of gates, location and number of turnstiles, escalators, stairs, ramps, passageways, intermediate concourses and platforms must be arranged to minimize walking distances and to prevent congestion. In this study, circulation of passengers is simulated in a quantitatively verifiable manner, taking into account how individuals interact with each other and with the physical obstacles in their environment in a metro station. Virtual experiments are performed to see the continuity and density of pedestrian flow at different levels of Haram Area East Metro Station of the first metro line of Madinah Al-Munawwarah, Saudi Arabia. According to the predictions, more than 40.000 passengers are expected to use this station in one hour after a Friday prayer during Ramadan period in the year of 2040. That means a critically high travel demand and it is really significant to design the most convenient underground station for these passengers to fulfil the necessary requirements.

  7. Background noise spectra of global seismic stations

    Wada, M.M.; Claassen, J.P.

    1996-08-01

    Over an extended period of time station noise spectra were collected from various sources for use in estimating the detection and location performance of global networks of seismic stations. As the database of noise spectra enlarged and duplicate entries became available, an effort was mounted to more carefully select station noise spectra while discarding others. This report discusses the methodology and criteria by which the noise spectra were selected. It also identifies and illustrates the station noise spectra which survived the selection process and which currently contribute to the modeling efforts. The resulting catalog of noise statistics not only benefits those who model network performance but also those who wish to select stations on the basis of their noise level as may occur in designing networks or in selecting seismological data for analysis on the basis of station noise level. In view of the various ways by which station noise were estimated by the different contributors, it is advisable that future efforts which predict network performance have available station noise data and spectral estimation methods which are compatible with the statistics underlying seismic noise. This appropriately requires (1) averaging noise over seasonal and/or diurnal cycles, (2) averaging noise over time intervals comparable to those employed by actual detectors, and (3) using logarithmic measures of the noise.

    2011-05-01

    The history, current status and future prospects of water recovery at space stations are discussed. Due to energy, space and mass limitations physical/chemical processes have been used and will be used in water recovery systems of space stations in the near future. Based on the experience in operation of Russian space stations Salut, Mir and International space station (ISS) the systems for water recovery from humidity condensate and urine are described. A perspective physical/chemical system for water supply will be composed of an integrated system for water recovery from humidity condensate, green house condensate, water from carbon dioxide reduction system and condensate from urine system; a system for water reclamation from urine; hygiene water processing system and a water storage system. Innovative processes and new water recovery systems intended for Lunar and Mars missions have to be tested on the international space station.

  11. Central station market development strategies for photovoltaics

    1980-01-01

    Federal market development strategies designed to accelerate the market penetration of central station applications of photovoltaic energy system are analyzed. Since no specific goals were set for the commercialization of central station applications, strategic principles are explored which, when coupled with specific objectives for central stations, can produce a market development implementation plan. The study includes (1) background information on the National Photovoltaic Program, photovoltaic technology, and central stations; (2) a brief market assessment; (3) a discussion of the viewpoints of the electric utility industry with respect to solar energy; (4) a discussion of commercialization issues; and (5) strategy principles. It is recommended that a set of specific goals and objectives be defined for the photovoltaic central station program, and that these goals and objectives evolve into an implementation plan that identifies the appropriate federal role.

  12. Thermoelectrical power stations in 1967

    Medici, M. (University of Padova, Italy)

    1968-01-01

    In Italy in 1967, geothermal electric power production was 2.66% of the national energy production. The implementation of traditional and nuclear power plants is described. The trend in conventional thermoelectric power plants is characterized by ever-increasing block capacities (100-160 MW at present), they are expected to increase to 600 MW in Europe and to 1200 MW in the USA 10 years from now. Nuclear power plants with pressurized-water reactors, boiling-water reactors, and graphite-gas reactors have been built recently in Italy. Studies are being conducted in the area of high-speed reactors and breeder reactors. A description is presented of a power station using geothermal energy. At the end of 1967, geothermal power plants with an electrical capacity of 340 MW were in operation. Generally, U.S. thermoelectrical engine blocks with high productivity were used. The thermodynamic characteristics of these blocks are described in detail. The most powerful engine in the field in Italy- a turbocompressore Franco Tosi- was constructed in the ENEL central Castlenuovo Val Cecina in the Larderello region. The compressor is fed by a combined flow of steam, CO/sub 2/ and H/sub 2/S. It is characterized by a load of 22 t/h and an input pressure of 0.0905 atm at the outlet. The absorbed power is 2.28 MW at a velocity of 50 rotations/sec. Thirty figures are presented.

    Jusupović, Fatima; Juricić, Mojca; Rudić, Aida; Hazihalilović, Jasminka; Kasumović, Merima; Kalesic, Mirela

    2005-01-01

    BMI is frequently used in different studies as indicator of nutritional status. When BMI exceeds the limit values then it represents the risk factor leading to different diseases; therefore it is important to calculate BMI for young persons. In cases when BMI differs from the recommended value it is necessary to apply different measures in order to prevent diseases. The aim of this paper was to assess the present status and on the basis of the result obtained to assess the need for eventual preventive activities leading to healthy life stytes. This study was performed on a sample of 1544 school boys and girls aged eight, ten and fourteen attending first, third and seventh class of elementary school. The study covered four municipalities of Tuzla Canton: Tuzla, Lukavac, Gradanica and Kladanj, and both urban and rural areas. We used the method of anthropometric measurement (IBP International Biological Program) of body mass and body height, followed by calculation of BMI and statistical evaluation. This study found that the average BMI of girls and boys is increasinglongitudinally with the age, with significant change between 10 years and 14 years, without significant gen der difference. Boys aged eight have BMI 15.76, len years 16.52 and are similar to the BMI of girls aged eight 15.44 and ten years 16.59. Fourteen-year-old girls have BMI which is 19.54, higher than the BMI of boys at the same age which is 18.75. Having in mind the range of BMI percentile values for normal nutritional status (from 5 to 85) the values for eight years old boys ranged from 14.1 to 19.4, for ten-year-old boys from 13.4 to 19.2, and for fourteen-year-old boys from 13.6 to 19.5. The values for girls showed the following results; for eight-year-old girls the value ranged from 13.9 to 20.6; for ten-year-old girls t'rom 13.5 to 20.5 and fourteen-year-old girls from 13.7 to 19.6.

There is also increasing evidence about the impact of PR on mental health and, in particular, mood disorders. We aimed to identify how depression in chronic obstructive pulmonary disease (COPD patients in Victoria, Australia, is being managed in PR, to identify the prevalence of depressive symptoms among COPD patients who attend PR, and to determine whether patients with depressive symptoms or anxiety symptoms dropped out of PR early.Method: Of 61 PR clinics, 44 were invited and 22 agreed to participate. Telephone interviews were conducted to see how depression and anxiety in COPD patients were being recognized and managed in these clinics. A total of 294 questionnaires were distributed to patients by clinic coordinators to determine the prevalence of anxiety/depression, as measured by the Hospital Anxiety and Depression Scale. Coordinators were contacted to provide information on whether respondents dropped out of rehabilitation early or continued with their treatment at 2–4 months post program.Results: Seven clinics were not aware of local guidelines on assessment/treatment/management of mood. Four clinics did not use any screening tools or other aids in the recognition and management of depression and/or anxiety. Overall, eight clinics participating in this study requested advice on suitable screening tools. The patient survey indicated that the mean depression score on the Hospital Anxiety and Depression

  18. Re-attenders to the emergency department of a major urban hospital serving a population of 290,000.

    Ramasubbu, B

    2015-01-01

    The national Emergency Medicine Programme (EMP) in Ireland, defines a re-attender as any patient re-presenting to the Emergency Department (ED) within 28 days with the same chief complaint. A retrospective, electronic patient record audit was carried out on all re-attenders to Connolly ED during November 2012. There were 2919 attendances made up from 2530 patients; 230 patients re-attended a total of 389 times. The re-attendance rate was 13% (389\\/2919). 63 (27%) were frequent presenters. There was a significantly higher admission rate at second attendance than first (89 (39%) vs 39 (17%), p < 0.001). 25% (57\\/230) of patients \\'left before completion of treatment\\' (LBCT) at first attendance (significantly higher than the number at second attendance (p < 0.01)). 14\\/57 (25%) of those who LBCT at first attendance required admission at second attendance. 28\\/89 (31%) of second attendance admissions were failed discharges from first attendance. Reasons for re-attendance are multi-factorial and include both patient and departmental factors.

    Jacob, Rebecca; Wong, Mai Luen; Hayhurst, Catherine; Watson, Peter; Morrison, Cecily

    2016-08-01

    Frequent attendance to the emergency department (ED) is a growing public health concern. Designing services for frequent attenders poses challenges, given the heterogeneous nature of this group. This was a two-part observational study identifying frequent attenders from ED records. The first stage studied trends and developed personas with emphasis on differentiating moderate frequent attenders (attending between 5 and 20 times per year) and extreme frequent attenders (attending more than 20 times). Stage 2 included a case note review of 100 consecutive frequent attenders. Results showed an increase in frequent attendance from 2.59% to 4.12% over 8 years. Moderate frequent attenders accounted for 97%. Of the 100 frequent attenders studied, 45% had medically unexplained symptoms (MUS), associated with younger age (p0.05). In conclusion, the ED is a useful hub for identifying frequent attenders with MUS, particularly among moderate frequent attenders; service design for this group should consider a 'whole-systems approach' with integration between primary and secondary care, including specialist liaison psychiatry services where appropriate.

  20. Home birth attendants in low income countries: who are they and what do they do?

    Garces Ana

    2012-05-01

    Full Text Available Abstract Background Nearly half the world’s babies are born at home. We sought to evaluate the training, knowledge, skills, and access to medical equipment and testing for home birth attendants across 7 international sites. Methods Face-to-face interviews were done by trained interviewers to assess level of training, knowledge and practices regarding care during the antenatal, intrapartum and postpartum periods. The survey was administered to a sample of birth attendants conducting home or out-of-facility deliveries in 7 sites in 6 countries (India, Pakistan, Guatemala, Democratic Republic of the Congo, Kenya and Zambia. Results A total of 1226 home birth attendants were surveyed. Less than half the birth attendants were literate. Eighty percent had one month or less of formal training. Most home birth attendants did not have basic equipment (e.g., blood pressure apparatus, stethoscope, infant bag and mask manual resuscitator. Reporting of births and maternal and neonatal deaths to government agencies was low. Indian auxilliary nurse midwives, who perform some home but mainly clinic births, were far better trained and differed in many characteristics from the birth attendants who only performed deliveries at home. Conclusions Home birth attendants in low-income countries were often illiterate, could not read numbers and had little formal training. Most had few of the skills or access to tests, medications and equipment that are necessary to reduce maternal, fetal or neonatal mortality.

  1. [THE DISCUSSION CONCERNING THE PLACE OF LECTURES AND COMPULSORY LECTURE ATTENDANCE IN MEDICAL EDUCATION].

    Reis, Shmuel

    2016-04-01

    Luder shows that there is a lack of correlation between lecture attendance in medical school and examination performance, and thus draws attention to a discourse concerning the place of lectures and lecture attendance enforcement in 2015 and beyond. The paper addresses 4 questions: First, what is the current place of the traditional lecture in the education of medical students? Second, are there alternatives to this format of teaching? Third, what are the educational consequences of mandating lecture attendance; and fourth, should there be such enforcement? The author discusses these questions and concludes that lectures should be used sparingly, after a careful evaluation that they have an added value over learning away from the classroom. Furthermore, that there are clear guidelines on how to make the traditional lecture enhanced and educationally effective, as well as alternatives such as the "flipped classroom", e-learning and more to lectures. In addition, that lectures frequently drive learning negatively and enforcing attendance in Israel entails serious unintended consequences such as a need to monitor attendance, and a host of disciplinary adverse reactions. Finally, that besides lecture efficiency and economy (when having added value) one reason to consider compulsory attendance, may be when poor attendance negatively influences teachers morale.

  2. Personal volatile organic compound (VOC) exposure of children attending elementary schools adjacent to industrial complex

    Park, Kun-Ho; Jo, Wan-Kuen

    The major deficiency in linking the effects of environmental exposure to children's health is the lack of data on the exposure of children to hazardous environmental pollutants. Accordingly, the present study compared the personal volatile organic compound (VOC) exposure of children from four elementary schools at different proximities to the Daegu Dyeing Industrial Complex (DDIC) and adjacent to different traffic densities. The personal air concentrations of four VOCs (toluene, m, p-xylenes, and o-xylene) were significantly higher for the children attending the school (S1) closest to the boundary of the DDIC compared to the children attending the school (S2) further away. The DDIC was the likely primary cause for the elevated personal air concentrations of the four VOCs in the children attending the school nearest the DDIC. The personal exposure to toluene and methyl tertiary-butyl ether (MTBE) for the children attending the school near a major roadway with a high traffic density was significantly higher than that for the children attending the school near a roadway with a low traffic density. The difference in the breath concentrations was generally similar to the difference in the personal air concentrations among the children from the four schools. In contrast to the children attending schools in low-income areas, the children attending schools in high-income areas exhibited no significant difference in the concentrations of any of the target VOCs in the personal air and breath samples between the children living with and without a smoker in the home.

  3. Antenatal care attendance, a surrogate for pregnancy outcome? The case of Kumasi, Ghana.

    Asundep, Ntui N; Jolly, Pauline E; Carson, April; Turpin, Cornelius A; Zhang, Kui; Tameru, Berhanu

    2014-07-01

    Antenatal care (ANC) has been shown to influence infant and maternal outcomes. WHO recommends 4 ANC visits for uncomplicated pregnancies. However, pregnant women in Ghana are required to attend 8-13 antenatal visits. We investigated the association of ANC attendance with adverse pregnancy outcomes (defined as low infant birth weight, stillbirth, preterm delivery or small for gestational age). A quantitative cross-sectional study was conducted on 629 women, age 19-48 years who presented for delivery at two selected public hospitals and 16 traditional birth attendants from July to November 2011. Socio-demographic and antenatal information were collected using a structured questionnaire. ANC attendance, medical and obstetric/gynecological history were abstracted from maternal antenatal records. Data were analyzed using Chi square and logistic regression. Twenty-two percent of the women experienced an adverse outcome. Eleven percent of the women attended 5 children) was also associated with adverse birth outcomes. Women screened for syphilis or use of insecticide-treated bed nets had a 40 and 36% (p = 0.0447 and p = 0.0293) reduced likelihood of experiencing an adverse pregnancy outcome respectively. After adjusting for confounders, attending <4 antenatal visits was associated with adverse pregnancy outcome compared with ≥4 ANC visits (Adjusted OR 2.55; 95% CI 1.16-5.63; p = 0.0202). Attending <4 antenatal visits and high parity were associated with adverse pregnancy outcomes for uncomplicated pregnancies.

    2015-07-01

    Full Text Available Este artigo originou-se de um posicionamento crítico sobre o modo como exercemos o ofício de pesquisadores. Intrigou-nos o que fazemos nas e com as interações de linguagem. É com esse olhar que se discute a atividade de diálogo realizada entre pesquisadores e um trabalhador (engenheiro de petróleo, que faz parte das atividades de pesquisa realizadas no projeto “Trabalho, saúde e segurança na indústria petrolífera offshore da Bacia de Campos-RJ”. Entende-se que a necessidade de enfrentar o problema com a linguagem é anterior ao uso de métodos que envolvam atividades de diálogo, ou seja, a teorização com a linguagem começa na concepção e preparação dos métodos. A análise realizada ressalta o desenvolvimento de um gênero de discurso de novo tipo, surgido na historicidade de outros - conversa espontânea e entrevista - no interior da comunidade dialógica formada, a fim de dar suporte à promoção da saúde e segurança no trabalho do setor petrolífero.

  6. Prevalence of Giardia and Cryptosporidium species in dog park attending dogs compared to non-dog park attending dogs in one region of Colorado.

    Wang, Andrea; Ruch-Gallie, Rebecca; Scorza, Valeria; Lin, Philip; Lappin, Michael R

    2012-03-23

    Dog parks are very popular in urban areas, but there are no current studies attempting to correlate visits to dog parks and risk of colonization by enteric parasites. The purpose of this study was to determine whether dog park visitation is associated with an increased prevalence of enteric parasites or an increase in prevalence of gastrointestinal signs in dogs in northern Colorado. Feces from dogs owned by veterinary students or Veterinary Teaching Hospital staff members were submitted with a completed survey form detailing dog park attendance rates, fecal character scores, and other clinical information. Feces were examined microscopically for parasites after sugar centrifugation, for Giardia spp. cysts and Cryptosporidium spp. oocysts by a commercially available immunofluorescence assay (FA) and the FA positive samples were genotyped after PCR amplification. The Giardia assemblages were determined using the glutamate dehydrogenase (GDH) β-giardin and triose phosphate isomerase (TPI) genes and the Cryptosporidium species were determined using the heat shock protein-70 gene. A total of 129 fecal samples were assayed; 66 were from dog park attending dogs and 63 were from non-dog park-attending dogs. The overall parasite prevalence rate was 7.0% (9 of 129 samples). Dog park attending dogs were more likely to be positive for Giardia or Cryptosporidium than non-dog park-attending dogs (p=0.0279), but there was no association of gastrointestinal signs with dog park attendance or with fecal flotation or FA results. The five Giardia isolates were assemblage C and/or D and the one Cryptosporidium isolate was Ctenocephalides canis.

  7. Modelling of Train Noise in Underground Stations

    Kang, J.

    1996-08-01

    TNS, a computer model for predicting the temporal and spatial distribution of train noise in underground stations, is developed. The train is regarded as a series of sections, and the train noise distribution in a station is calculated by inputting the sound attenuation from a train section source in the underground system (i.e., the station and tunnel). This input can be obtained by physical scale modelling. The prediction by TNS in an underground station in London shows good agreement with site measurements. A series of computations in the station demonstrates that: (1) the overall level of the train noise in the area near the end walls is slightly less than the other areas; (2) some conventional architectural acoustic treatments in the station are effective when a train is still in the tunnel but not as helpful when the train is already in the station; and (3) train noise has a significant effect on the speech intelligibility of public address systems as measured by the Speech Transmission Index (STI).

  8. Traditional Birth Attendants in Rural Northern Uganda: Policy, Practice, and Ethics.

    Rudrum, Sarah

    2016-01-01

    The current emphasis on skilled attendants as a means to reduce maternal mortality contributes to a discouraging policy environment for traditional birth attendants (TBAs). They continue to attend a significant number of births, however, such that their role and the policies and practices affecting their work remain important to understanding maternity health care and maternal health in the global South. In this article, I examine the policies and practices governing community elders practicing as TBAs in rural northern Uganda. This discussion is relevant to health workers in developing countries and to scholars in fields such as women's studies, sociology, and public health.

    1991-01-01

    The minimum Space Station Freedom accommodations required for initial assembly, repair, and refurbishment of the Lunar aerobrake were investigated. Baseline Space Station Freedom support services were assumed, as well as reasonable earth-to-orbit possibilities. A set of three aerobrake configurations representative of the major themes in aerobraking were developed. Structural assembly concepts, along with on-orbit assembly and refurbishment scenarios were created. The scenarios were exercised to identify required Space Station Freedom accommodations. Finally, important areas for follow-on study were also identified.

    Todays, petroleum companies consider that despite the constant increase of petroleum consumption, petroleum will remain the main energy source for at least 40 years. However, after the Iraq conflict, new regional situations are changing. China, for instance, with its growing up demand, will change the physiognomy of the oil market. In parallel, from Indonesia to Africa, petroleum and religion interfere and explain the new conflict areas. As for the US strategy, which is not limited to the energy paradigm, it largely integrates energy in the main lines of its diplomacy, from the 'Wide Middle East' to the 'Sahel initiative', and in its position with respect to Venezuela.

    2007-01-01

    Full Text Available Abstract The objective of the study was to conduct a process and outcomes evaluation of the International AIDS Conference (IAC. Reaction evaluation data are presented from a delegate survey distributed at the 2004 IAC held in Thailand. Input and output data from the Thailand IAC are compared to data from previous IACs to ascertain attendance and reaction trends, which delegates benefit most, and host country effects. Outcomes effectiveness data were collected via a survey and intercept interviews. Data suggest that the host country may significantly affect the number and quality of basic science IAC presentations, who attends, and who benefits most. Intended and executed HIV work-related behavior change was assessed under 9 classifications. Delegates who attended 1 previous IAC were more likely to report behavior changes than attendees who attended more than 1 previous IAC. The conference needs to be continually evaluated to elicit the required data to plan effective future IACs.

    Full Text Available This paper focuses on the development of a networked thumb print-based attendance management system. Now, more than ever, it has become necessary to give more thought to the methods of time and attendance management. The traditional time clock, manual attendance registering often no longer makes sense and simply does not meet the needs of the modern work environment. This system offers a comprehensive software solution that will streamline company's operations, and simplify timekeeping. Nowadays, the need of a solution for Time and Attendance in the modern company is a necessity. It is important to be able to manage and control the workers by means of a system of control of times and schedules.

  4. Students' Perceptions of the Long-Term Impact of Attending a "CSI Science Camp"

    Yanowitz, Karen L.

    2016-07-01

    A science summer camp is a popular type of informal science experience for youth. While there is no one model of a science camp, these experiences typically allow for more focused and in-depth exploration of different science domains and are usually hands-on and participatory. The goal of this research was to examine the impact of a short science camp program approximately 1 year after students attended the camp. Overall, the results revealed that attending a 2-day forensic science camp had a positive and continuing influence on the participants. Students' science self-efficacy increased immediately after attending the camp and remained higher than pre-camp levels approximately 1 year later. Students were able to articulate why they believed the camp had a long-term impact on their lives. Furthermore, participants attributed a higher level of engaging in additional informal STEM-related activities during the academic year as a result of attending the camp.

  7. Effects of aging on the novelty P3 during attend and ignore oddball tasks.

    Friedman, D; Kazmerski, V A; Cycowicz, Y M

    1998-09-01

    The effects of attention were assessed on novelty P3 amplitude and scalp distribution elicited by environmental sounds in young and elderly volunteers who participated in either actively attended or ignored oddball conditions. For the young, novelty P3 amplitude decreased with time on task during both attend and ignore sequences. Amplitude decrements were greatest at frontal sites during the attend condition, but at all sites during the ignore condition. A reliable amplitude decrement was not observed for the elderly in either the attend or ignore oddball series. The data suggest that attention differentially activates multiple generators that contribute to scalp-recorded novelty P3 activity. The lack of novelty P3 habituation seen in the elderly is consistent with changes in frontal lobe function as age increases.

    A science summer camp is a popular type of informal science experience for youth. While there is no one model of a science camp, these experiences typically allow for more focused and in-depth exploration of different science domains and are usually hands-on and participatory. The goal of this research was to examine the impact of a short science camp program approximately 1 year after students attended the camp. Overall, the results revealed that attending a 2-day forensic science camp had a positive and continuing influence on the participants. Students' science self-efficacy increased immediately after attending the camp and remained higher than pre-camp levels approximately 1 year later. Students were able to articulate why they believed the camp had a long-term impact on their lives. Furthermore, participants attributed a higher level of engaging in additional informal STEM-related activities during the academic year as a result of attending the camp.

    In the last two decades Resistive Plate Chambers were employed in the Cosmic Ray Experiments COVER-PLASTEX and ARGO/YBJ. In both experiments the detectors were housed indoors, likely owing to gas distribution requirements and the need to control environment variables that directly affect RPCs operational stability. But in experiments where Extended Air Shower (EAS) sampling is necessary, large area arrays composed by dispersed stations are deployed, rendering this kind of approach impossible. In this situation, it would be mandatory to have detectors that could be deployed in small standalone stations, with very rare opportunities for maintenance, and with good resilience to environmental conditions. Aiming to meet these requirements, we started some years ago the development of RPCs for Autonomous Stations. The results from indoor tests and measurements were very promising, both concerning performance and stability under very low gas flow rate, which is the main requirement for Autonomous Stations. In this w...

  14. Strategic planning for the International Space Station

    Griner, Carolyn S.

    1990-01-01

    The concept for utilization and operations planning for the International Space Station Freedom was developed in a NASA Space Station Operations Task Force in 1986. Since that time the concept has been further refined to definitize the process and products required to integrate the needs of the international user community with the operational capabilities of the Station in its evolving configuration. The keystone to the process is the development of individual plans by the partners, with the parameters and formats common to the degree that electronic communications techniques can be effectively utilized, while maintaining the proper level and location of configuration control. The integration, evaluation, and verification of the integrated plan, called the Consolidated Operations and Utilization Plan (COUP), is being tested in a multilateral environment to prove out the parameters, interfaces, and process details necessary to produce the first COUP for Space Station in 1991. This paper will describe the concept, process, and the status of the multilateral test case.

    Our aim is to assess the benefits and limitations of using the redundant visibility information in regular phased array systems for improving the calibration. Regular arrays offer the possibility to use redundant visibility information to constrain the calibration of the array independent of a sky model and a beam models of the station elements. It requires a regular arrangement in the configuration of array elements and identical beam patterns. We revised a calibration method for phased array stations using the redundant visibility information in the system and applied it successfully to a LOFAR station. The performance and limitations of the method were demonstrated by comparing its use on real and simulated data. The main limitation is the mutual coupling between the station elements, which leads to non-identical beams and stronger baseline dependent noise. Comparing the variance of the estimated complex gains with the Cramer-Rao Bound (CRB) indicates that redundancy is a stable and optimum method for cali...

  20. Space Station concept development group studies

    Powell, L. E.

    1984-01-01

    The NASA study activities in preparation for a Space Station began in the early 1970's. The early studies included many in-house NASA and contracted studies. A group of representatives from all the NASA Centers, titled the Space Station Concept Development Group (CDG) was involved in the studies which led to the initiation of the Space Station Program. The CDG studies were performed over a period of approximately one year and consisted of four phases. The initial phase had the objective to determine the functions required of the station as opposed to a configuration. The activities of the second phase were primarily concerned with a sizing of the facilities required for payloads and the resources necessary to support these mission payloads. The third phase of studies was designed to develop a philosophical approach to a number of areas related to autonomy, maintainability, operations and logistics, and verification. The fourth phase of the study was to be concerned with configuration assessment activities.
