Exposure of Petrol Station Attendants and Auto Mechanics to Premium Motor Sprit Fumes in Calabar, Nigeria  

International Nuclear Information System (INIS)

A population-based-cross-sectional survey was carried out to investigate the potential risk of exposure to premium motor spirit (PMS) fumes in Calabar, Nigeria, among Automobile Mechanics (AM), Petrol Station Attendants (PSA) and the general population. Structured questionnaire was administered on the randomly chosen subjects to elicit information on their exposure to PMS. Duration of exposure was taken as the length of work in their various occupations. Venous blood was taken for methaemoglobin (Met Hb) and packed cells volume (PCV). Mean Met Hb value was higher in AM (7.3%) and PSA (5.8%) than in the subjects from the general population (2.7%). PCV was lower in PSA (30.8%), than AM (33.3%) and the subjects from the general population (40.8%). Met Hb level was directly proportional, and PCV inversely related, to the duration of exposure. The study suggested increased exposure to petrol fumes among AM, PSA, and Met Hb as a useful bio marker in determining the level of exposure to benzene in petrol vapour.

The soil remediation fund for petrol stations in Belgium  

International Nuclear Information System (INIS)

In the Flemish, Brussels-Capital and Walloon Region, petrol stations are subjected to strict operating standards, to avoid soil contamination as much as possible in the future. Besides these operating requirements, regional authorities also issued regulations regarding the remediation of contaminated soils. For many petrol stations operators, land owners and users, these rules and regulations are a heavy financial burden. As a result, the soil contamination threaten to become a public charge, due to a lack of adequate remediation by the stakeholders. After years of negotiating between the petroleum industry and the government the negotiations finally resulted in a cooperation agreement between the Federal Government, the Flemish, Walloon and Brussels-Capital Regions regarding the execution and financing of the remediation of contaminated soil at petrol stations. The cooperation agreement, signed in Brussels on 13 December 2002 and approved by all Regions and the Federal Government, makes it possible to provide a structured approach for the remediation of the soil contamination at petrol stations in Belgium. In the cooperation agreement the establishment of an Inter-regional Soil Remediation Committee is provided to guarantee the fund's independence and to observe the fund's operation. The official start is given through the accreditation of BOFAS by the Inter-regional Soil Remediation Committee. To calculate the amount that would be necessary for the remediation of thuld be necessary for the remediation of the soil contamination at petrol stations and the contribution to the fund, an economical research has been carried out. This research indicated that the total cost for the remediation of the soil contamination at petrol stations in Belgium is situated between 400 and 450 million EUR. BOFAS has calculated that 5.000 petrol stations can comply with the conditions mentioned in the cooperation agreement. Operators, Owners or Actual users can submit an application if they comply with the legally established conditions, which depend on the situation at their petrol station. It is estimated that 4.000 petrol stations will submit an application. These conditions take into account European legislation concerning support measures and competition law. The legislator took learning experiences in the Netherlands and Denmark as a basis. These countries have launched similar funds in the past. BOFAS however goes further in its financial support

Directory of Open Access Journals (Sweden)

Full Text Available Aim: Evaluation of nuclear anomalies in exfoliated buccal epithelial cells of petrol station attendants and oral squamous cell carcinoma patients. Materials and me thods: Study was carried out on 60 subjects. 20 petrol pump attendants, 20-squamous cell carcinoma patients and 20 healthy subjects. They were asked questions regarding their life style and personal factors (age, duration of working in the petrol pump, alcohol consumption and smoking habits were statistically analyzed. Buccal smears were taken from respective sites and stained with Periodic Acid Schiff. Results: There was a significant number of nuclear abnor - malities seen in oral carcinoma group and then followed by the petrol pump workers. Discussion: Micronuclei are identified with presence of a main nucleus and one or more smaller nuclei (micronuclei in the cells. The micronuclei are usually round or oval in shape and their diameter may range between 1/3 and 1/16, the diameter of the main nucleus. Nuclear abnormalities were classified accord - ing to Tolbert et al (1992. These criteria are intended to classify buccal cells into categor ies that distinguish between ‘normal’ and ‘abnormal’ based on their aberrant nuclear morphology.

State of subsoil in a former petrol station: physicochemical characterization and hydrocarbon contamination evaluation  

Science.gov (United States)

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 content dependent: maximum of adsorption taken place at minimum pH what encourage protonation and minimum clay content in the subsoil make organic compounds infiltration downstream easier. It could be noticed the importance of physicochemical subsoil characterization and contamination assessment in the subsoil of petrol stations in order to avoid the hydrocarbons pollution of the groundwater. Then plan the best remediation technique according to this characterization taking into account the residual hydrocarbon concentration in the subsoil and the associated risk for human and ecosystems.

Lipoid Pneumonia in a Gas Station Attendant  

Science.gov (United States)

The exogenous lipoid pneumonia, uncommon in adults, is the result of the inhalation and/or aspiration of lipid material into the tracheobronchial tree. This is often confused with bacterial pneumonia and pulmonary tuberculosis due to a nonspecific clinical and radiologic picture. It presents acutely or chronically and may result in pulmonary fibrosis. We describe here a case of lipoid pneumonia in a gas station attendant who siphoned gasoline to fill motorcycles; he was hospitalized due to presenting with a respiratory infection that was hard to resolve. The patient underwent bronchoscopy with bronchoalveolar lavage, which, on cytochemical (oil red O) evaluation, was slightly positive for lipid material in the foamy cytoplasm of alveolar macrophages. Due to his occupational history and radiographic abnormalities suggestive of lipoid pneumonia, a lung biopsy was performed to confirm the diagnosis. The patient was serially treated with segmental lung lavage and showed clinical, functional, and radiological improvement. PMID:25374742

Oil fuel delivery optimization for multi product and multi depot: the case of petrol station replenishment problem (PSRP)  

Science.gov (United States)

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%.

Geo-enviromental monitoring system of the oil storages on petrol stations  

Directory of Open Access Journals (Sweden)

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.

Variability of benzene exposure among filling station attendants  

International Nuclear Information System (INIS)

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

Cortical atrophy detected by computed tomography in gasoline station attendants  

Energy Technology Data Exchange (ETDEWEB)

The contribution of leaded gasoline in the presence of abnormal calcifications or cortical atrophy seen in computed tomographies (CT) of the head of occupationally exposed professionals working in the centre of Athens is evaluated. One hundred and twenty-two head CTs from gas station employees and traffic-exposed professionals (taxi and bus drivers) were analyzed for evidence of cortical atrophy or abnormal calcifications. Blood lead level (BLL) of these lead occupationally exposed groups was compared with 37 non-exposed subjects. Results: All three occupationally exposed-to-lead groups had similar blood lead levels compared to the non-exposed group and within the currently accepted norms for lead. No abnormal calcifications were found. Cortical atrophy was more frequently seen in the gas station employees group using univariate and multivariate analysis. In the logistic regression model gas station employment had a stronger impact in developing cortical atrophy [odds ratio of 6.43 (1.46-28.3, 95% CI)] than BLL [odds ratio of 1.4 (1.01-2.05, 95% CI)]. These results show that employment in gasoline stations may be associated with detectable cortical atrophy in imaging studies and suggest the contribution of a leaded gasoline to its development.

Laboratory study on the bioremediation of diesel oil contaminated soil from a petrol station / Estudo laboratorial da biorremediação de solo de posto de combustíveis contaminado com óleo diesel  

Scientific Electronic Library Online (English)

Full Text Available SciELO Brazil | Language: English Abstract in portuguese O objetivo do presente estudo foi investigar possíveis métodos para aumentar a taxa de biodegradação aeróbia de hidrocarbonetos (tratamentos ex-situ). Neste trabalho, processos de biorremediação foram aplicados a um solo arenoso com alto nível de contaminação ocasionada por um vazamento de um tanque [...] de armazenamento de óleo diesel subterrâneo em um posto de combustíveis. Experimentos em escala laboratorial (respirômetros de Bartha) foram utilizados para avaliar a biodegradação do óleo diesel. Estímulo da biodegradação foi realizado utilizando-se as técnicas de bioestímulo (adição de soluções de nitrogênio e fósforo ou surfactante Tween 80) e de bioaumento (consórcio bacteriano isolado de um sistema de landfarming). Para investigar as interações entre os fatores otimizadores, e encontrar a melhor combinação entre esses agentes, o estudo foi baseado em um delineamento experimental fatorial completo. A eficiência de biodegradação foi simultaneamente medida com dois métodos: respirométrico (produção de CO2 microbiano) e cromatografia gasosa. Testes de toxicidade aguda com Daphnia similis foram aplicados para examinar a eficiência dos processos em termos de geração de produtos menos tóxicos. Resultados mostraram que todas as estratégias de biorremediação aceleraram a biorremediação natural do solo contaminado e os melhores resultados foram obtidos quando os tratamentos tinham adição de nutrientes. Dados respirométricos indicaram uma máxima mineralização de hidrocarbonetos de 19,8%, obtida com a combinação dos três agentes, com uma remoção de hidrocarbonetos totais de petróleo (TPH) de 45,5% em 55 dias de tratamento. No final dos experimentos, duas espécies predominantes de bactéria foram isoladas e identificadas como Staphylococcus hominis e Kocuria palustris. Abstract in english 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).

Meet the Maximally Exposed Member of the Public: The Service Station Attendant for Spent Nuclear Fuel Going to Yucca Mountain  

International Nuclear Information System (INIS)

According to the 1999 Draft Environmental Impact Statement (DEIS) for the proposed Yucca Mountain repository site, members of the public along transportation routes by which spent nuclear fuel (SNF) and high-level radioactive waste (HLW) is shipped will receive annual radiation doses less than 100 mrem/yr, the international (ICRP) and national (Department of Energy, Nuclear Regulatory Commission) radiation limit for members of the public. For the ''Mostly Truck'' national transportation scenario, the DEIS specifically concludes that the maximally exposed member of the public, a service station attendant along the primary shipping route will receive no more than 100 mrem/yr, or 2.4 rem over 24 years. Based on the assumptions in the DEIS scenarios, however, it is highly likely that service station attendants along shipping routes will be called upon to fuel and service the rigs carrying SNF and HLW to Yucca Mountain. After reevaluating the DEIS, and making realistic alternative assumptions where necessary, the authors conclude that these attendants are likely to receive substantially more than 100 mrem/yr external dose, and perhaps several times that dose (up to 500 mrem/yr), unless mitigating measures are adopted. This is particularly true in Western states where refueling opportunities are limited, and the distances between fuel sources in rural areas may be up to 100 miles

Los resultados obtenidos también muestran que valores iguales o superiores a 54,79 µg/L son indicadores de exposición directa al Pb, permitiendo establecer valores de tolerancia entre los intervalos de 24,89 y 112,69 µg/L. Estos valores de referencia se encuentran por debajo de lo descripto por Burguera y cols. (1997, lo cual podría atribuirse al reemplazo gradual de la gasolina con plomo, en los últimos años, que ha llevado a una disminución de un 27% en los niveles de plomo en sangre, en comparación con un estudio similar realizado en esta misma ciudad en el año 1997.In this work the lead (Pb content in blood was determined in petrol station workers in the city of Merida-Venezuela and in a group of people not occupationally exposed.

The results obtained also show that values equal to or higher than 54.79 µg/L are indicative of direct exposure to Pb, making it possible to establish tolerance values between the 24.89 and 112.69 µg/L intervals. These reference values are below what was reported by Burguera et al (1997 which could be attributed to the gradual substitution of gasoline for lead that has originated a 27% decrease in lead levels in blood, if compared with a similar study carried out in the same city in 1997.

The neurobehavioural consequences of petrol (gasoline) sniffing.  

Science.gov (United States)

This review will introduce petrol (gasoline) sniffing as a specific form of substance abuse. Petrol sniffing is associated with dysfunctions that range in severity from subtle cognitive impairment to encephalopathy and death, and these are discussed with respect to their specific neurological and cognitive bases. Morbidity and mortality rates will also be presented that suggest severe central nervous system damage occurs as a result of petrol sniffing. The neuropharmacological actions of tetraethyl lead and volatile hydrocarbons, the components within petrol, and their contributions to the effects of sniffing petrol are investigated. Reports of human occupational or recreational exposure to either lead additives or volatile hydrocarbons (i.e. inhalants) have provided evidence of the neurological and cognitive effects that may also occur with petrol sniffing. Petrol sniffing causes a progressive decline of cognitive function that eventually leads to permanent neurological changes. PMID:11835986

Effects of changes in petrol taxation  

International Nuclear Information System (INIS)

The purpose of this study is to estimate and discuss some of the policy-relevant effects of petrol tax changes. Our approach is to seek to separate the extent to which each of the following variables is affected by changes in the price of petrol: (i) car ownership (ii) car use (iii) petrol consumption per km. The estimates show that the sum of (i) and (ii) results in a price-elasticity with respect to 'car traffic' equal to -0.2 in the short run, and -0.3 in the long run. Because of possibilities to increase the fuel efficiency of cars, the price-elasticity of 'petrol demand' is substantially greater: -0.3 in the short run and of the order of -0.7 in the long run. One conclusion is: A petrol price rise is considerably more effective as a measure for energy and environmental policy than for transport policy. The effect of petrol tax changes to the total tax revenue is also discussed. At last, the regional welfare distribution effects are treated in the form of estimation of regional differences to the reduction in the consumers' surplus from a petrol price increase. 19 refs., 15 figs., 17 tabs

An attitude study on the environmental effects of rationing petrol in Tehran  

International Nuclear Information System (INIS)

The objective of this study is to assess the environmental effects of implementing petrol rationing and the issuance of fuel smartcards in central Tehran. The results and their application are significant from the perspective of preserving fuel sources and protecting the environment, both of which being among the goals of sustainable development. Through the analysis of soft data (owners of automobile and light pickup trucks attitude), 3 general hypotheses were assessed and the result was compared to hard data (the traffic situation information, petrol consumption and air pollution). The soft data was gathered using a comprehensive questionnaire which randomly distributed among 2000 automobile and pickup truck drivers in the central Tehran area who were at petrol stations to refuel their vehicles. The gathered data was then analyzed at two levels: descriptive and inferential. The results of this research reveal that according to the soft data, the smartcard project has resulted in a decline in traffic and petrol consumption and a rise in air pollution; furthermore, the positive cultural effects of this project have been comparatively prominent. The actual figures show that the project has led to lower traffic load and air pollution but petrol consumption remains the same as before.

The Health Impacts of Ethanol Blend Petrol  

Directory of Open Access Journals (Sweden)

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 their older counterparts, will make up a higher proportion of the fleet in the future. Hence the beneficial effects of reductions in particulate matter become less significant as the fleet as a whole produces lower emissions.

Neurological and cognitive recovery following abstinence from petrol sniffing.  

Science.gov (United States)

Anecdotal observations suggest that neurological impairments associated with petrol (gasoline) sniffing resolve with abstinence, although these effects have not been proven empirically. Severe exposure to leaded petrol may induce a lead encephalopathy that extends beyond any acute intoxication and requires emergency hospital treatment. Previously, in chronic petrol sniffers, we showed neurological, saccadic, and cognitive abnormalities that were more severe in petrol sniffers with a history of hospitalization for lead encephalopathy, and that correlated with blood lead levels and the length of time of sniffing petrol. Ex-petrol sniffers showed a qualitatively similar but quantitatively less severe pattern of impairment. Petrol sniffing was stopped completely in one of the study communities by modifying social, occupational, and recreational opportunities. After 2 years, we obtained biochemical and neurobehavioral (neurological, saccade, and cognitive) data from all available participants of the earlier study including 10 nonsniffers and 29 chronic petrol sniffers, with six of these individuals previously receiving hospital treatment for lead encephalopathy. Here, we report that blood lead was reduced and that neurobehavioral impairments improved, and in many cases normalized completely. The most severe petrol-related neurobehavioral impairment was observed among individuals who had longer histories of abuse and higher blood lead levels, and among petrol sniffers with a history of lead encephalopathy. Those with the greatest extent of neurobehavioral impairment showed the greatest degree of improvement with abstinence, but were less likely to recover completely. This is the first direct evidence that neurological and cognitive impairment from chronic petrol sniffing ameliorates with abstinence and may recover completely. PMID:15714227

Attendance at UN Symposium on the Development of Utilization of Geothermal Resources and a visit to Larderello geothermal power station  

Energy Technology Data Exchange (ETDEWEB)

The Larderello geothermal power station is described. A tour was provided as part of the UN Symposium on the Development of and Utilization of Geothermal Resources held from September 22 to October 1, 1970, in Italy (about 400 participants from 43 countries). At Larderello, there were 17 geothermal power plants whose total output capacity was reportedly 390,600 kW as of September of 1970. The amount of steam used per turbine was about 20 kg/kWh for turbines without condensers and about 10 kg/kWh for turbines with condensers. There were many small-scale plants, and procedures such as unmanned operation or remote control were being tested in two or three plants.

Idiosyncrasies in Australian petrol price behaviour: evidence of seasonalities  

International Nuclear Information System (INIS)

It has been argued that there are certain idiosyncrasies in Australian petrol price behaviour. To the extent that these idiosyncrasies result in large magnitude differences in petrol prices, they may be exploited by consumers to significantly reduce their household expenditure on the product. Similarly, such seasonalities may influence retailers in their purchase and storage decision. The objective of this paper is to test for seasonalities in the Australian retail petrol market. The approach adopted is similar to that for determining calendar anomalies as documented in the financial and commodity markets literature. We find that a monthly seasonal effect is pronounced with petrol prices lower in the months of February-May and highest in July and August. A day-of-the-week effect is also apparent and is manifest in all petrol prices for capital cities (Adelaide, Brisbane, Melbourne and Sydney) across various years. However, the half-month effect, as is common in stock returns, is not observed. Moreover, contrary to popular belief that petrol prices are higher surrounding holidays, no evidence of the holiday effect is found. In Brisbane and Melbourne, petrol prices also have some relationship to the mood of consumers, as proxied using weather conditions. This is not observed in Adelaide and Sydney. (Author)

Correlation between petrol lead additive consumption and atmospheric lead concentrations in Perth, Western Australia  

Science.gov (United States)

The impact of unleaded petrol (ULP), and the variation in lead (Pb) content of leaded petrol (LP), on air quality in Perth, Western Australia, has been assessed using correlations between atmospheric Pb concentrations and petrol Pb consumption figures for the period 1982-1987 during which ULP was introduced in 1985. The study underlines the importance of taking into account the variability in the Pb content of LP when predicting atmospheric lead concentrations from petrol consumption data.

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

Science.gov (United States)

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. PMID:25872020

Health Risk Assessment of Ambient Air Concentrations of Benzene, Toluene and Xylene (BTX in Service Station Environments  

Directory of Open Access Journals (Sweden)

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.

Petrol with octane number 91 and 98 will disappear  

International Nuclear Information System (INIS)

Next or may be already this year Petrol with octane number 91 and 98 will disappear from the market of the Slovak Republic. A final deadline has not been set yet. According to an explanation provided by deputy general manager for refinery and marketing of Slovnaft, a.s., Bratislava, Bela Kelemen the reason for this decision is lack of interest drivers show for this type of fuel. The consumption of diesel, on the other hand, is growing rapidly. According to representatives of Slovnaft the balance between offer and demand is tense in case of diesel, petroleum and the most used petrol with octane number 95. In their opinion this is caused mainly by the cold weather

Optical sensor for the determination of adulteration in petrol: design and development  

Science.gov (United States)

In this paper, we report design and development of optical sensor for the determination of adulteration in petrol using optical time-domain reflectometer (OTDR). OTDR is generally used to find out fault in optical fibers but we effectively use this technique for the determination of the percentage of adulteration in petrol. This OTDR method enables detection of adulteration in petrol very accurately. The OTDR measurement method reported in this paper is easy to carry out and also a cost effective tool for the determination of adulteration in petrol.

Science.gov (United States)

Recently, the lead content of various environmental components has decreased in response to replacement of leaded petrol by unleaded petrol. In India, 15 research studies are here assessed with respect to lead concentrations in various environmental components during the leaded petrol phase (before 1996), the transitional phase (1996-2000) and the unleaded petrol phase (2000 onwards). The Ganga River Water exhibited a decrease in lead concentration from 18.0 microg/l in 1988 to 3.1 microg/l in 2001. In Lucknow urban centre, mean lead concentrations in the urban air decreased from 1.6 microg/m(3) in 1994 to 0.2 microg/m(3) in 2002. Lead concentrations in Dalbergia sissoo tree leaves also decreased from 18.7 microg/g dry wt. in 1994 to 8.3 microg/g dry wt. in 2004. Mean blood-lead levels of children from Mumbai, Chennai, Bangalore, Amritsar and Lucknow urban centres have fallen from 18.1 microg/dl in the leaded petrol phase to 12.1 microg/dl in the unleaded petrol phase. The petrol-lead phase-out effort in India has reduced lead concentrations in the various environmental components after 2000. It will help to reduce the exposure of millions of people to environmental lead. PMID:16764909

Combining synchronous fluorescence spectroscopy with multivariate methods for the analysis of petrol-kerosene mixtures.  

Science.gov (United States)

Synchronous fluorescence spectroscopy (SFS) is a rapid, sensitive and nondestructive method suitable for the analysis of multifluorophoric mixtures. The present study demonstrates the use of SFS and multivariate methods for the analysis of petroleum products which is a complex mixture of multiple fluorophores. Two multivariate techniques principal component regression (PCR) and partial least square regression (PLSR) have been successfully applied for the classification of petrol-kerosene mixtures. Calibration models were constructed using 35 samples and their validation was carried out with varying composition of petrol and kerosene in the calibration range. The results showed that the method could be used for the estimation of kerosene in kerosene-mixed petrol. The model was found to be sensitive, detecting even 1% contamination of kerosene in petrol.

Coal petrol and SNG - alternatives for the future  

International Nuclear Information System (INIS)

If in the decades to come no alternatives are found for the conventional fuels, i.e. petrol and diesel oil, in vehicle propulsion and if the non-energetic use of mineral oil is maintained on a large scale for economic reasons although there is a technical possibility of substitution by synthesizing substances other than those derived from mineral oil, the domains of traffic and non-energetic uses will largely remain oil-dependent. Model calculations have shown however that this demand could theoretically be satisfied by the upgrading of coal, which would require substantial additional expenditure. But even if all possible energy measures are taken and on the assumption of rising oil imports, the development of nuclear power is indicated, as coal cannot act as a substitute for nuclear power and a source of fuel at the same time. The necessary volume of capital expenditure is, however, justified only if this is done with the consistent aim of reducing the dependence of oil imports. Development of even part of the coal liquefaction potential would have a favourable and lasting effect in terms of energy policy on the dependence of oil imports all over the world. (Auth.)

LCAs of petrol and diesel - A literature review  

Energy Technology Data Exchange (ETDEWEB)

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.

THE CONSEQUENCES OF LEAD PETROL USE ON LEAD CONTENT IN CABBAGE ALONG THE MOTORWAY  

OpenAIRE

Besides the negative ecological consequences, during the production of the motor petrol (alkyl lead as anti–knock compound), as well as the application (combustion in motor engines), there are the ecological consequences manifested by deposition of Pb in the soil beside the motorway. At the same time this is the end of the life cycle of the petrol. However, Pb enters the human consumption chain through the plants that absorb Pb from the soil, and it is also deposited in the human body. The ...

Effects of Gasoline Inhalation on Menstrual Characteristics and the Hormonal Profile of Female Petrol Pump Workers  

Directory of Open Access Journals (Sweden)

Full Text Available Increasing numbers of young women are employed as gasoline station attendants in most developing countries despite the lack of empirical data on the adverse reproductive health effect of this solvent. This study therefore sought to assess the effects of gasoline inhalation on the serum sex hormone profile and menstrual characteristics of female gasoline station attendants in Nigeria, given the global increase in the rate of infertility and the existing evidence on the reproductive toxicity of gasoline constituents. A site-by-site cross-sectional study of 117 female gasoline pump attendants and 118 age-matched controls was carried out between September 2011 and November 2012. The following 3 instruments were used for data collection: a semi-structured questionnaire, a female sex hormone profile assay and exposure status measures. The prevalence of menstrual disorders among the exposed and unexposed women was 37.2% and 28.5% respectively. Exposure to gasoline was significantly associated with disorders in both menstrual cycle length and quantity of flow. Specifically, exposed women had a greater than threefold increased risk of a menstrual disorder, with an odds ratio (OR of 3.25 for abnormal cycle length and OR of 4.16 for abnormal quantity of flow. In addition, longer duration of exposure (>1 year was significantly associated with higher likelihood of menstrual disorders. There were also persistent low serum levels of estradiol, and fluctuating levels of other reproductive hormones. Gasoline inhalation may interfere with ovarian functions leading to disordered menstrual characteristics and female sex hormone profiles, as well as future reproductive impairment.

Modification Design of Petrol Engine for Alternative Fueling using Compressed Natural Gas  

Directory of Open Access Journals (Sweden)

Full Text Available This paper is on the modification design of petrol engine for alternative fuelling using Compressed Natural Gas (CNG. It provides an analytical background in the modification design process. A petrol engine Honda CR-V 2.0 auto which has a compression ratio of 9.8 was selected as case study. In order for this petrol engine to run on CNG, its compression had to be increased. An optimal compression ratio of 11.97 was computed using the standard temperature-specific volume relationship for an isentropic compression process. This computation of compression ratio is based on an inlet air temperature of 30oC (representative of tropical ambient condition and pre-combustion temperature of 540oC (corresponding to the auto-ignition temperature of CNG. Using this value of compression ratio, a dimensional modification Quantity =1.803mm was obtained using simple geometric relationships. This value of 1.803mm is needed to increase the length of the connecting rod, the compression height of the piston or reducing the sealing plate’s thickness. After the modification process, a CNG engine of air standard efficiency 62.7% (this represents a 4.67% increase over the petrol engine, capable of a maximum power of 83.6kW at 6500rpm, was obtained.

International Nuclear Information System (INIS)

This paper deals with the flow behaviour conventional petrol, bioethanol and their blends, especially E15 and E85. The temperature dependence density and kinematic viscosity of samples have been measured and modelled. The rotary rheometer has been used to the measuring temperature dependence kinematic viscosity of fuel and blends. The digital densitometer with the fuel scale has been used to the measuring temperature dependence density of fuel and blends. The range of temperature measurement has been stated from the -10 to 40 degree C. The mathematic models (polynomial and exponential function) have been created according to the general formulae. The coefficients of determination R/sup 2/ have achieved high values 0.99 for temperature dependence density and from 0.89 to 0.97 for temperature dependence kinematic viscosity. The created mathematical models could be used to the predict flow behaviour of petrol, bioethanol and their blends. (author)

A house with its own filling station  

International Nuclear Information System (INIS)

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

Performace Test and Engine Emission on Acid Oleic Oxygenated as Additives Petrol  

Directory of Open Access Journals (Sweden)

Full Text Available The objective of this study is to investigate the effect of oxygenated oleic acid additives in standard petrol on the engine performance and the exhaust emissions. The 4-stroke 1.5 litre engine was used on the engine test bed coupled to eddy current electric dynamometer which is also connected to CADET V12 control system and exhaust gas analyser IMR2000/2000P. The oxygenated oleic acid additives used for this experiment is fixed at 0.2% by volume due to limited quantity available. Two types of test were carried out first test is with variable speed and no loads and the second test is at constant speed of 1,400 rpm with variable loads. The experimental results showed that the brake power increased by 2%, torque by 2%, brake thermal efficiency by about 7% and specific fuel consumption decreased by about 10%. The exhaust emissions analysed are carbon monoxide, (CO, carbon dioxide (CO2 and oxides of nitrogen (NOx. The result by comparing the oxygenated petrol with the standard petrol indicated that CO gas emission depend on the engine speed which decreased with increasing speed up to 1,600 rpm and increased after that speed on test without load. The CO also decreased by about 28% on the test with loads. The emission of CO2 increased by 2.7% for tests with load and by 8% for tests without loads. The NOx emission decreased by 9% for test without load and about 7% for test with load. This study indicates that engine performance is improved by adding 0.2% oxygenated additives to standard petrol.

Study of performance and emission characteristics of a direct injection diesel engine using rice bran oil ethanol and petrol blends  

Directory of Open Access Journals (Sweden)

Full Text Available In this study, influence on the engine performance and exhaust emissions of a naturally aspirated, single cylinder direct injection diesel engine has been experimentally investigated using pure rice bran oil (RBO, and its 2.5%, 5% and 7.5% blends with ethanol (ERBO and petrol (PRBO. The influence on the viscosity of the RBO with the addition of the ethanol and petrol from 200C to 700C has also been studied. The tests conducted from no load to full load of the engine with an increment of 20%of the load. The experimental test results showed that the kinematic viscosity reduced maximum by 28.3% and 31.7% with addition of ethanol and petrol respectively. The maximum brake thermal efficiency of 26.83% with ERBO2.5 and 27% with PRBO7.5 was obtained. Among the ethanol blends the minimum brake specific fuel consumption of 0.312 is observed with ERBO7.5 and among the petrol blends the minimum brake specific fuel consumption of 0.299 is observed with PRBO2.5 at full load of the engine. Lower CO emissions of 0.021 with ERBO2.5 and higher CO emissions of 0.032 observed with ERBO7.5. The CO emissions of petrol blends observed between the values of ethanol blends. The unburnt hydrocarbons increased with load in both the ethanol and petrol blends. The lower NOx emissions of 920 with ERBO2.5 and higher NOx emissions of 1045 measured with PRBO7.5. The CO2 increased to 3.72 with PRBO7.5 and reduced to 2.45 with ERBO7.5. The unused O2 increased 17.2%with ethanol blends and reduced to 13.1% with petrol blends. The smoke reduced with both the blends and lower value of 34.0% observed with PRBO7.5.

Reclamation of petrol oil contaminated soil by rhamnolipids producing PGPR strains for growing Withania somnifera a medicinal shrub.  

Science.gov (United States)

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. PMID:25480735

An analytic study of applying Miller cycle to reduce NOx emission from petrol engine  

International Nuclear Information System (INIS)

An analytic investigation of applying Miller cycle to reduce nitrogen oxides (NOx) emissions from a petrol engine is carried out. The Miller cycle used in the investigation is a late intake valve closing version. A detailed thermodynamic analysis of the cycle is presented. A comparison of the characters of Miller cycle with Otto cycle is presented. From the results of thermodynamic analyses, it can be seen that the application of Miller cycle is able to reduce the compression pressure and temperature in the cylinder at the end of compression stroke. Therefore, it lowers down the combustion temperature and NOx formation in engine cylinder. These results in a lower exhaust temperature and less NOx emissions compared with that of Otto cycle. The analytic results also show that Miller cycle ratio is a main factor to influence the combustion temperature, and then the NOx emissions and the exhaust temperature. The results from the analytic study are used to analyse and to compare with the previous experimental results. An empirical formula from the previous experimental results that showed the relation of NOx emissions with the exhaust temperature at different engine speed is presented. The results from the study showed that the application of Miller cycle may reduce NOx emissions from petrol engine

Emissions from a vehicle fitted to operate on either petrol or compressed natural gas.  

Science.gov (United States)

The purpose of this work was to evaluate the physical and chemical properties of emission products from a six-cylinder sedan car under a variety of operating conditions, before and after it has been converted to compressed natural gas (CNG) fuel. The specific focus of the measurements was on emission levels and characteristics of ultra fine particles and the emission levels together with the emissions of gaseous pollutants for a range of operating conditions before and up to 3 months after the vehicle was converted are presented and discussed in the paper. The investigations showed that converting a petrol operating vehicle to CNG has the potential of reducing some of the emissions and thus risks, while it does not appear to have an impact on others. In particular there was no statistically significant change in the emission of particles for the vehicle operating on petrol, before the conversion, compared to the emissions for the vehicle operating on CNG, after the conversion. There was a significant lowering of emissions of total polycyclic aromatic hydrocarbons and formaldehyde when the vehicle was operated on CNG, and a reduction of global warming potential was also observed when the vehicle was run on CNG, but the later gain is only at high vehicle speeds/loads, and would thus have to be considered in view of traffic and transport models for the region (in these models vehicle speed is an important parameter).

Does class attendance still matter?  

Directory of Open Access Journals (Sweden)

Full Text Available This paper presents a study on the impact of class attendance on academic performance in a second year Electronics Engineering course module with online notes and no mandatory class attendance policy. The study shows that class attendance is highly correlated to academic performance, despite the availability of online class notes. In addition, there is significant correlation between class attendance and non-class contact with the lecturer and between student performance in the first year of university study and current academic performance and class attendance. However, there is no correlation between pre-university academic performance and current class attendance and academic performance. The study finds no gender bias in either class attendance or academic performance. Lastly, this being a course module open to students following different degree programmes, the study finds that a student’s choice of degree programme has no impact on class attendance and academic performance in this particular course module.

Effect of sample geometry on synchronous fluorimetric analysis of petrol, diesel, kerosene and their mixtures at higher concentration  

Energy Technology Data Exchange (ETDEWEB)

A comparison of synchronous fluorescence scan (SFS) spectra of petrol, diesel and their mixtures with kerosene in front surface, 45{sup o} and 90{sup o} angle sample geometry as obtainable from a commercial fluorimeter reveals that 90{sup o} angle geometry provides certain distinct characteristics to SFS spectra. The presence of extensive inner filter effects and resonance energy transfer in petroleum products are the major causes of the distinctive characteristics of these spectra. These characteristics enable the development of calibration plots for mixture samples (petrol-kerosene and diesel-kerosene) based on the shift in {gamma}{sub SFS{sup max}} and SFS intensity. This novel method shows promise in detecting and estimating the contamination of petrol and diesel by kerosene. Calibration graphs obtained from SFS intensity measurement are found to be efficacious in the whole range 0-90% v/v of kerosene, and give a good linearity in the adulteration range generally found in the field (0-50% v/v) for petrol and diesel. The method is simple, rapid and superior both in terms on sensitivity (0.1% v/v) and accuracy to other analytical methods used for petroleum product analysis. (Author)

Impact of Organic Solvents and Environmental Pollutants on the Physiological Function in Petrol Filling Workers  

Directory of Open Access Journals (Sweden)

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 a significant toxic effect of solvents and air pollutants on workers exposed for longer duration. Improved detection and prevention technologies are needed to answer environmentally related health questions for petrol filling workers.

Price setting under cost uncertainty and menu costs - the case of the Danish petrol market  

International Nuclear Information System (INIS)

This paper derives the optimal pricing policy for a firm facing menu costs and stochastic production cost. The pricing policy is a boundary pricing policy and numerical comparative static analysis shows how exogenous parameters - the drift and variance of the production cost, the discount factor and the menu costs - affect the boundaries. Analyzing daily data for the Danish petrol price illustrates that a boundary pricing policy indeed has been followed for the period 1988-1992, with occasional shifts in both the desired mark-up and more importantly in the width of the bounds. While the theoretical model can say nothing of the shifts in desired mark-up, changes in the width of the bounds are found to be consistent with the implications of the model. (au)

Some investigations in design of low cost variable compression ratio two stroke petrol engine  

CERN Document Server

Historically two stroke engine petrol engines find wide applications in construction of two wheelers worldwide, however due to stringent environmental laws enforced universally; these engines are fading in numbers. In spite of the tight norms, internationally these engines are still used in agriculture, gensets etc. Several designs of variable compression ratio two stroke engines are commercially available for analysis purpose. In this present investigation a novel method of changing the compression ratio is proposed, applied, studied and analyzed. The clearance volume of the engine is altered by introducing a metal plug into the combustion chamber. This modification permitted to have four different values of clearance value keeping in view of the studies required the work is brought out as two sections. The first part deals with the design, modification, engine fabrication and testing at different compression ratios for the study of performance of the engine. The second part deals with the combustion in engi...

Chemometric study of excitation-emission matrix fluorescence data: quantitative analysis of petrol-kerosene mixtures.  

Science.gov (United States)

Products of petroleum crude are multifluorophoric in nature due to the presence of a mixture of a variety polycyclic aromatic hydrocarbons (PAHs). The use of excitation-emission matrix fluorescence (EEMF) spectroscopy for the analysis of such multifluorophoric samples is gaining progressive acceptance. In this work, EEMF spectroscopic data is processed using chemometric multivariate methods to develop a reliable calibration model for the quantitative determination of kerosene fraction present in petrol. The application of the N-way partial least squares regression (N-PLS) method was found to be very efficient for the estimation of kerosene fraction. A very good degree of accuracy of prediction, expressed in terms of root mean square error of prediction (RMSEP), was achieved at a kerosene fraction of 2.05%. PMID:18935824

Petrol contaminated groundwater treatment with air-stripper in Balassagyarmat, Hungary  

International Nuclear Information System (INIS)

Hydrocarbon contaminated groundwater is a common environmental problem in Hungary. Leakage of underground storage tanks, pipe break or illegal tapping as well as lorry accidents can be mentioned as main reasons. MEGATERRA Ltd. elaborated, adopted and tested several groundwater clean-up methods. These methods are based on detailed survey and investigation, sampling and analysis, delineation of contaminated groundwater, risk assessment, establishment of monitoring wells, pumping tests and remediation action plan. One of these methods was implemented by MEGATERRA Ltd. in Balassagyarmat, Hungary. Contamination source was a 10 m3 vol. simple wall underground fuel-storage tank, which had been emptied. When the remediation started in April 1998, the petrol had already been accumulated on the ground water table forming a 5-7 m wide and 10-15 m long plume being expanded to SSE-NNW direction. The area of the dissolved hydrocarbon contaminated groundwater-body was 1 000 m2 and its concentration reached up to 30-40 mg/l TPH. The free-phase hydrocarbon layer was 10 cm thick. For the remediation of contaminated groundwater MEGATERRA Ltd. applied pump and treat method, namely groundwater pumping using extraction well, skimming of free-phase hydrocarbon, stripping of the contaminated ground water in air-stripper tower and draining of the treated groundwater into a drainage ditch. In the centre of the plume we established an extraction well with 300 mm diameter i an extraction well with 300 mm diameter in a 500 mm borehole. Peristaltic skimmer pump was used inside the extraction well to remove the free phase petrol from the ground water surface.Because of the intense volatility of the pollutant we applied aeration (stripping) technology. The extracted contaminated groundwater was cleaned in air-stripper equipment being able to eliminate efficiently the volatile pollutants from the water. The aeration tower is a compact cylindrical shaped column with 650 mm in diameter. Its height depends on the pollutant's type The extracted contaminated groundwater was conducted to the top of the tower and sprinkled into the air- stripper. A ventilator was connected to the bottom of the stripper, which blew the air with high pressure against the water stream. During the operation 4 544 m3 groundwater was pumped out, cleaned, drained and 110 l of free phase hydrocarbon was skimmed

Specifying Complex Systems in Object-Z: A Case Study of Petrol Supply Systems  

Directory of Open Access Journals (Sweden)

Full Text Available As modern complex systems become increasingly large, sophisticated, feature-rich and data-intensive, people have recognized the importance of precisely and unambiguously specifying them with formal methods for a number of years. This paper advocates the use of Object-Z, a formal specification language, in the description of complex systems. Object-Z is an extension to the Z language to facilitate specification in an object-oriented style. The notation Object-Z builds on Z's strengths in modeling complex data and algorithms, and on its new class structuring's strengths in succinctly specifying the various relationships and communication between objects in a large system. In detail, first we describe informally the syntax and semantics of Object-Z, highlighting those features that facilitate decomposing a large system into a collection of interacting objects and thus separating concerns. Then, we demonstrate the use of Object-Z by presenting a case study of a petrol supply system, illustrating how the system runs by communicating the constituent objects. Finally, we discuss several issues we encountered in this exercise, which may serve as feedback to the development of Object-Z.

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

International Nuclear Information System (INIS)

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 1011 to 1013 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 ?g km-1 at 40 to about 1000 ?g 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 LPGith LPG

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

Science.gov (United States)

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.

On board emission and fuel consumption measurement campaign on petrol-driven passenger cars  

Science.gov (United States)

Realistic emission and fuel consumption rates of petrol-driven cars were determined by on-the-road experiments in 1995. A validated, in-house developed, on-board measuring system was used. Six three-way catalyst (TWC) cars and one carburetted non-catalyst car were measured. The effects of road type, driving behaviour and cold start on CO, HC and NO x emissions and fuel consumption were analysed. In real traffic situations, emissions for TWC cars were found to be at least 70% lower than for the non-catalyst car. For TWC cars, emissions decreased across the board from city to rural and motorway traffic. Without a catalyst, motorway traffic resulted in the highest NO x emissions. Compared to normal driving, aggressive driving gave emissions which were up to four times higher. Except for NO x, calm driving resulted in lower emissions still. Comparable fuel consumption rates were obtained from normal and calm driving. Those from aggressive driving were higher, by as much as 40% in city traffic. Cold starts resulted in significantly higher CO and HC emission values than hot starts. These differences were less pronounced for NO x. Emissions from TWC cars were higher than generally expected, compared to the European emission limit values (91/441/EEC) and the emission factors used in Flanders and the Netherlands (Klein,1993) for the national emission inventories. Low-emitting cars during the emission test on a chassis dynamometer, as prescribed by the 91/441/EEC directive, did not necessarily give low emissions in real traffic situations.

Ultra-fast selective sensing of ethanol and petrol using microwave-range metamaterial complementary split-ring resonators  

Science.gov (United States)

An extremely compact metamaterial microstrip sensor based on complementary split-ring-resonators (CSRRs) has been fabricated for chemical sensing. This device exhibits a resonance with high rejection at 4.5 GHz, which demonstrates concomitant variations when exposed to liquids of various permittivity values. The resonance frequency of CSRR is sensitive to the change in nearby dielectric material. The sensing of petrol shows a shift in frequency with a sharp dip in transmission, while, with ethanol, the frequency shift is accompanied with increase in the power of the signal. The ultra-fast reversibility and repeatability offers good headway towards hybrid fuel sensing applications.

Is there an asymmetry in the response of diesel and petrol prices to crude oil price changes? Evidence from New Zealand  

Energy Technology Data Exchange (ETDEWEB)

This paper examines how pre-tax petrol and diesel prices in New Zealand respond to changes in crude oil prices using an asymmetric error correction model. Our results show that oil companies adjust diesel prices upwards faster than they adjust them downwards, and the difference is statistically significant. However we find no statistical evidence for an asymmetry in the adjustment of petrol prices even though the magnitude of estimated coefficients suggests a faster response to rising prices. As diesel pricing is not as competitive as petrol pricing, calls for further government actions and monitoring of the oil market may be justified. Our findings also have important implications for the conduct of monetary policy as the pass-through of crude oil price changes can affect cost-push inflation. (author)

Energy Technology Data Exchange (ETDEWEB)

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)

Advanced introduction of cleaner petrol and diesel in the Netherlands. An analysis of the emission potential and cost effectiveness  

International Nuclear Information System (INIS)

In 2005 the European Union is to introduce tighter environmental standards for road vehicle fuels. The emissions of new passenger vehicles, delivery vans and heavy good vehicles will then have to satisfy even more stringent criteria, as will petrol and diesel fuel composition, the sulphur content of which must then be down from respectively 150 and 350 parts per million to 50 ppm. In the case of petrol, the maximum permitted aromatics content is also to be reduced, from 42% to 35%. There are two motives for introducing tighter environmental criteria for vehicle fuels. In the first place it will have the direct effect of immediately reducing the noxious emissions of all road vehicles running on these fuels, because of improvements to the combustion process. In addition, there will also be a significant indirect effect. Availability of low-sulphur fuels opens the door for several new vehicle technologies. In the case of petrol vehicles it permits introduction of direct-injection (DI) lean-burn engines with catalytic NOx absorption. In diesel vehicles new types of catalytic systems can be introduced, including 'particle traps' to reduce PM10 emissions. These technologies require low-sulphur fuels to be effective. An environmental downside of these cleaner fuels is that refinery production is more energy-intensive. EU member states are free to support implementation of these 'cleaner' fuels at an earlier date if they so desire. The objective of the present study is to proe objective of the present study is to provide background data for a possible decision on accelerated introduction of these fuels in the Netherlands. The aim of this study is to investigate the environmental effects and economic costs of accelerated introduction in the Netherlands of 'cleaner' fuels satisfying the EU's '2005 standards'. Two possible dates have been considered for earlier implementation: November 2001 and June 2003. November 2001 has been taken because this is when Germany will be introducing a tax incentive for low-sulphur petrol and diesel fuels. June 2003 lies exactly halfway between this date and January 2005. It has been assumed that the 'cleaner' fuels will immediately capture 100% of the market. Diesel and petrol have been examined separately, given the fact that little synergy will be created through simultaneous introduction of the two 'clean' fuels. The direct environmental effects of these fuels on the existing vehicle fleet have been calculated using a model for the European Auto-Oil programme updated by the TNO Road Vehicles Research Unit to account for the most recent developments. The indirect environmental effects have been estimated using literature data and TNO expertise. The cost estimates are based on information provided by the oil industry and from the literature, augmented where necessary by our own calculations. Give the substantial uncertainties surrounding much of this data, in relevant cases we have made both pessimistic and optimistic estimates. By assigning a monetary value to the environmental effects these can be compared with costs, enabling the cost-effectiveness of accelerated introduction to be calculated. 37 refs

Hydrogen Filling Station  

Energy Technology Data Exchange (ETDEWEB)

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. This roadmap has the ability to become a tool for use by other road-mapping efforts in the hydrogen community. It could also become a standard template for other states or even countries to approach planning for a hydrogen future. Project partners also conducted a workshop on hydrogen safety and permitting. This provided an opportunity for the various permitting agencies and end users to gather to share experiences and knowledge. As a result of this workshop, the permitting process for the hydrogen filling station on the Las Vegas Valley Water District’s land was done more efficiently and those who would be responsible for the operation were better educated on the safety and reliability of hydrogen production and storage. The lessons learned in permitting the filling station and conducting this workshop provided a basis for future hydrogen projects in the region. Continuing efforts to increase the working pressure of electrolysis and efficiency have been pursued. Research was also performed on improving the cost, efficiency and durability of Proton Exchange Membrane (PEM) hydrogen technology. Research elements focused upon PEM membranes, electrodes/catalysts, membrane-electrode assemblies, seals, bipolar plates, utilization of renewable power, reliability issues, scale, and advanced conversion topics. Additionally, direct solar-to-hydrogen conversion research to demonstrate stable and efficient photoelectrochemistry (PEC) hydrogen production systems based on a number of optional concepts was performed. Candidate PEC concepts included technical obstacles such as inefficient photocatalysis, inadequate photocurrent due to non-optimal material band gap energies, rapid electron-hole recombination, reduced hole mobility and diminished operational lifetimes of surface materials exposed to electrolytes. Project Objective 1: Design, build, operate hydrogen filling station Project Objective 2: Perform research and development for utilizing solar technologies on the hydrogen filling station and convert two utility vehicles for use by the station operators Project Objective 3: Increase capacity of hydrogen filling station; add additional vehicle; conduct safety workshop; develop a roadmap for hydrogen development; accelerate the development of photovoltaic components Project Objective 4:

The object is to provide a method of operating a dual purpose power station so that the steam supply system is operated at a high load factor. The available steam not required for electricity generation is used to provide process heat and the new feature is that the process plant capacity is determined to make the most economic use of the steam supply system, and not to match the passout capacity of the turbine of the turbogenerator. The product of the process plant should, therefore, be capable of being stored. A dual-purpose power station with a nuclear-powered steam source, turbogenerating means connected to the steam source and steam-powered process plant susceptible to wide variation in its rate of operation is described.

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

Energy Technology Data Exchange (ETDEWEB)

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 the latest FTIR technology. Overall, the levels of these emissions were also mostly elevated at subnormal temperatures. Total vehicle mileage seemed not to affect cold-start emissions (CO and HC) at low temperatures. Nor did the overall durability of the emission control system appear to be worse in cold-climate conditions typical for Finland. The deterioration of the emissions performance in the tested vehicles either closely followed the average trend defined by the normal, assigned deterioration factors or was even lesser. The conclusions of this report underline the necessity of a separate low-temperature test in order to really effectively curb real-world emissions. Standards at normal temperature are no more effective alone, but need to be accompanied with additional requirements for good performance also in conditions closer to the everyday use, which comprises many cold-starts even in low ambient temperature conditions.

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.  

Science.gov (United States)

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. PMID:2225336

Study of exhaust emissions of direct injection diesel engine operating on ethanol, petrol and rapeseed oil blends  

International Nuclear Information System (INIS)

This article presents the bench testing results of a four stroke, four cylinder, direct injection, unmodified, diesel engine operating on pure rapeseed oil (RO) and its 2.5 vol%, 5 vol%, 7.5 vol% and 10 vol% blends with ethanol (ERO), petrol (PRO) and both improving agents applied in equal proportions as 50:50 vol% (EPRO). The purpose of the research is to examine the effect of ethanol and petrol addition into RO on diesel engine emission characteristics and smoke opacity of the exhausts. The biggest NOx emissions, 1954 and 2078 ppm, at 2000 min-1 speed generate blends PRO10 (9.72%) and EPRO5 (11.13%) against, 1731 and 1411 ppm, produced from ERO5 (12%) and ERO10 (13.2% oxygen) blends. The carbon monoxide, CO, emissions emitted from a fully loaded engine fuelled with three agent blends EPRO5-7.5 at maximum torque and rated speed are higher by 39.5-18.8% and 27.5-16.1% and smoke opacity lower by 3.3-9.0% and 24.1-17.6% comparing with RO case. When operating at rated 2200 min-1 mode, the carbon dioxide, CO2, emissions are lower, 6.9-6.3 vol%, from blends EPRO5-7.5 relative to that from RO, 7.8 vol%, accompanied by a slightly higher emission of unburned hydrocarbons HC, 16 ppm, and residual oxygen contents O2, 10.4-12.0 vol%, in the exhausts

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

Science.gov (United States)

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.

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

Science.gov (United States)

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.

Intermittent Attendance at Breast Cancer Screening  

Science.gov (United States)

Background To determine why women skip rounds and factors influencing return of previous non attenders (PNAs) to breast screening. Design and methods Retrospective, quantitative, structured questionnaire posted to 2500 women. First PNAs did not attend their first screening appointment in 2007/2008 but then attended in 2010; First Controls first attended in 2010 without missed previous appointments. Women who attended screening in 2006 or earlier then skipped a round but returned in 2010 were Subsequent PNAs; Subsequent Controls attended all appointments. Results More First Controls than First PNAs had family history of cancer (72.7% vs 63.2%; P=0.003); breast cancer (31.3% vs 24.8%; P=0.04). More PNAs lived rurally; more First PNAs had 3rd level education (33.2% vs 23.6%; P=0.002) and fewer had private insurance than First Controls (57.7% vs 64.8%; P=0.04). Excellent/good health was reported in First PNAs and First Controls (82.9% vs 83.2%), but fewer Subsequent PNAs than Subsequent Controls (72.7% vs 84.9%; P=0.000). Common considerations at time of missed appointment were had mammogram elsewhere (33% First PNA) and postponed to next round (16% First PNA, 18.8% Subsequent PNA). Considerations when returning to screening were similar for First PNAs and Subsequent PNAs: I am older (35.4%, 29.6%), I made sure I remembered (29%, 23.6%), could reschedule (17.6%, 20.6%), illness of more concern (16.5%, 19%). More First PNAs stated my family/friends advised (22.3% vs 15.2%) or my GP (12.6% vs 4.6%) advised me to attend, heard good things about BreastCheck (28.8% vs 13.6%). Conclusions Intermittent attenders do not fit socio-demographic patterns of non-attenders; GP recommendation and word of mouth were important in women’s return to screening. Fear and anxiety seem to act as a screening facilitator rather than an inhibitor. Significance for public health All breast cancer screening programmes strive to achieve and maintain a high level of attendance, as this is essential to reduce breast cancer mortality, together with cancer detection. While non-attendance has been widely studied, little is known about intermittent attenders. It is unclear why a woman chooses not to attend her breast screening appointment but then decides to respond positively to screening invitation two or more years later. The literature identifies many reasons why some women choose not to attend; but this study distinguishes those who then change their mind and return to screening. This study explores a sub-set of non-attenders which have, to date, been largely ignored, or grouped with people who never attend. This study will inform those struggling with non-attendance in their population based health programmes and will help to tackle the problem of non-attendance, which has adverse affects both economically and epidemiologically.

Frequent attenders in out-of-hours general practice care: attendance prognosis  

DEFF Research Database (Denmark)

OBJECTIVE: We aimed to describe the use of out-of-hours service and analyse attendance prognosis for frequent attenders and other groups of attenders, and to present a concept describing frequent attendance over time. METHODS: All adult attenders in 1990 were included in a 4-year follow-up study. Frequent attenders (FAs) were defined as those 10% among the attenders who most frequently used the out-of-hours service during a calendar year (12 months). This gave an intersection point of four or more contacts for frequent attenders. Three more groups were defined according to whether they had one, two or three contacts per year. The setting was out-of-hours general practice in Aarhus County, Denmark. Data were collected from the database of the Public Health Insurance, Aarhus County. The county had approximately 600,000 inhabitants, of whom 465,000 were aged 18 years and over. The subjects were 101,321 individuals aged 18 years and over who contacted the out-of-hours service in 1990. Outcome measures were attendance per year, age and sex. RESULTS: FAs made 42% of the out-of-hours contacts in 1990, and 33% of those who were FAs in 1990 were also FAs in 1991. Among the 1990 FAs, 67% contacted the out-of-hours service at least once in 1991, 25% contacted the service at least once in each of the following 4 years and 7% remained FAs in the following 4 years. The probability of being an FA rose with the duration of previous frequent attendance. Age above 50 years significantly predicted future status as an FA. Females made up two-thirds of FAs, but sex did not predict future frequent attendance. CONCLUSION: Frequent attendance could be regarded as a short-lived phenomenon. On the other hand, FAs were the most stable attenders of all groups of attenders over the years. Older FAs had the highest probability of remaining FAs

Home visiting and child health surveillance attendance.  

Science.gov (United States)

This project tested the hypothesis that low attendance rates at a Sure Start child health surveillance session might increase if appointments were preceded by intervention home visits from research assistants drawn from the local community. The assistants would explain the purpose of surveillance and discuss problems preventing attendance. A randomised control trial showed no increase in surveillance attendance after two-thirds of the intervention group were successfully visited. This negative finding was despite the partnership with local people acting as research assistants working well. Other factors that might have influenced attendance were investigated at an evaluation interview undertaken by community members in homes after the surveillance date. Only 55 per cent of the families could be contacted for evaluation. Six out of 10 of those who had no evaluation were the same families who had not attended the surveillance session. The reasons why these families missed surveillance sessions is yet to be identified. Further research is needed that explores the reason why some families do come for surveillance, the nature of the barriers to attendance in those who do not attend and to look for opportunities for fresh interventions that might give more children access to pre-school facilities.

Full Text Available Automatic face recognition (AFR technologies have seen dramatic improvements in performance over the past years, and such systems are now widely used for security and commercial applications. An automated system for human face recognition in a real time background for a college to mark the attendance of their employees. So Smart Attendance using Real Time Face Recognition is a real world solution which comes with day to day activities of handling employees. The task is very difficult as the real time background subtraction in an image is still a challenge (6. To detect real time human face are used and a simple fast Principal Component Analysis has used to recognize the faces detected with a high accuracy rate. The matched face is used to mark attendance of the employee.Our system maintains the attendance records of employees automatically. Manual entering of attendance in logbooks becomes a difficult task and it also wastes the time. So we designed an efficient module that comprises of face recognition to manage the attendance records of employees. Our module enrols the staff’s face (3. This enrolling is a onetime process and their face will be stored in the database. During enrolling of face we require a system since it is a onetime process. You can have your own roll number as your employee id which will be unique for each employee. The presence of each employee will be updated in a database. The results showed improved performance over manual attendance management system. Attendance is marked after employee identification. This product gives much more solutions with accurate results in user interactive manner rather than existing attendance and leave management systems.

Comparative analysis of environmental impact of S2P (Sunshine to Petrol) system for transportation fuel production  

International Nuclear Information System (INIS)

Graphical abstract: Display Omitted - Highlights: • We study solar fuels derived from CO2 and water using the S2P framework. • S2P fuels have lower environmental impact than conventional fuels. • We evaluate the economic, environmental, and social benefits of the S2P framework. - Abstract: A previous study on Sunshine to Petrol (S2P), a technology framework to produce liquid hydrocarbon fuels from CO2 and water using a concentrated solar energy source, focused on process development as well as economic evaluation. The study herein presents results from a life cycle assessment (LCA) approach to a comparative analysis of the environmental impacts of S2P-derived and petroleum-derived gasoline. Results reveal that S2P gasoline shows lower impact scores than the conventional gasoline for all evaluated impact categories. Based on the LCA results, we then analyze the environmental benefits including greenhouse gas (GHG) mitigation and external cost savings. We find that if S2P gasoline could be successfully introduced to satisfy the gasoline demand of a sample city, Victorville in east California, 3.6 Mt CO2-eq of the greenhouse gas (GHG) emissions (77% of the total regional emissions) would be mitigated based on the current fleet of vehicles. The lighter impact also corresponds to 4.2 M$ annual cost savings from avoided environment damage. More generally, for each million vehicles running on S2P gasoline there would be nearly $30 M in savings and 335 M gallons of gasoline displaced, which in turn results in nearly 25.8 Mt of CO2-eq avoided

Attendance Control System based on RFID technology  

Directory of Open Access Journals (Sweden)

Full Text Available In Kazakhstan, checking students' attendance is one of the important issues for universities, because many universities evaluate students attendance and while giving the final grade, professors consider their total number of appearances on classes during the whole semester. This brings to the idea of having some tool to control students attendance. Some universities prefer to use paper sheet for controlling attendance, whereas some universities prefer to use paper sheet for checking students' attendance and after this, fill out these information into a system manually, like Kazakh-British Technical University does. 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. Moreover, some students may call his/her friend as presence even though this student is currently absent. After thinking all these issues, authors of the following research paper decided to create a system that makes easier to check students attendance automatically, and this system is implemented in Suleyman Demirel University, Kazakhstan. Actually, this is the first time when such kind of system is being used in educational system of Kazakhstan. The system is based on RFID technology, and in this paper, details of this system are presented.

AIM: The study was designed: to determine the motivation of general practitioners attending education events; and to compare motivation and reasons for attendance pre- and post-Contract at commercial and non-commercial meetings, and at the different educational categories of Disease Management (DM), Health Promotion (HP) and Service Management (SM). METHOD: Two structured questionnaires were used. The first was sent to all general practitioners in the West of Scotland and asked about motivation pre-1990 Contract and the second, post-Contract, looked at motivation and reasons for attending a course as part of post course assessment. This latter was part of a much larger study evaluating continuing medical education. RESULTS: A total of 1161 practitioners responded to questionnaire I and 552 general practitioners attended 27 randomly selected postgraduate meetings. Finance was a motivator in 3.8% pre-Contract, and this increased to 33.3% post-Contract and was the most commonly stated reason for attendance in 81.3%. Financial incentive had the biggest influence on those attending HP sessions (91.5%), then SM (87.2%) and finally DM (78.6% (chi 2 = 8.68; P hospitality provided more alluring than scheme meetings (chi 2 = 28.6; P Planning for education must take into account the different motivational factors for the different categories. Reasons for attending commercial meetings differ from non-commercial ones and these events should be closely monitored. PMID:8983254

Intermittent attendance at breast cancer screening  

Directory of Open Access Journals (Sweden)

Full Text Available Background. To determine why women skip rounds and factors influencing return of previous non attenders (PNAs to breast screening. Design and methods. Retrospective, quantitative, structured questionnaire posted to 2500 women. First PNAs did not attend their first screening appointment in 2007/2008 but then attended in 2010; First Controls first attended in 2010 without missed previous appointments. Women who attended screening in 2006 or earlier then skipped a round but returned in 2010 were Subsequent PNAs; Subsequent Controls attended all appointments.Results. More First Controls than First PNAs had family history of cancer (72.7% vs 63.2%; P=0.003; breast cancer (31.3% vs 24.8%; P=0.04. More PNAs lived rurally; more First PNAs had 3rd level education (33.2% vs 23.6%; P=0.002 and fewer had private insurance than First Controls (57.7% vs 64.8%; P=0.04. Excellent/good health was reported in First PNAs and First Controls (82.9% vs 83.2%, but fewer Subsequent PNAs than Subsequent Controls (72.7% vs 84.9%; P=0.000. Common considerations at time of missed appointment were had mammogram elsewhere (33% First PNA and postponed to next round (16% First PNA, 18.8% Subsequent PNA. Considerations when returning to screening were similar for First PNAs and Subsequent PNAs: I am older (35.4%, 29.6%, I made sure I remembered (29%, 23.6%, could reschedule (17.6%, 20.6%, illness of more concern (16.5%, 19%. More First PNAs stated my family/friends advised (22.3% vs 15.2% or my GP (12.6% vs 4.6% advised me to attend, heard good things about BreastCheck (28.8% vs 13.6%.Conclusions. Intermittent attenders do not fit socio-demographic patterns of non-attenders; GP recommendation and word of mouth were important in women’s return to screening. Fear and anxiety seem to act as a screening facilitator rather than an inhibitor.

Father attendance in nurse home visitation.  

Science.gov (United States)

Our aim was to examine the rates and predictors of father attendance at nurse home visits in replication sites of the Nurse-Family Partnership (NFP). Early childhood programs can facilitate father involvement in the lives of their children, but program improvements require an understanding of factors that predict father involvement. The sample consisted of 29,109 low-income, first-time mothers who received services from 694 nurses from 80 sites. We conducted mixed-model multiple regression analyses to identify population, implementation, site, and nurse influences on father attendance. Predictors of father attendance included a count of maternal visits (B = 0.12, SE = 0.01, F = 3101.77), frequent contact between parents (B = 0.61, SE = 0.02, F = 708.02), cohabitation (B = 1.41, SE = 0.07, F = 631.51), White maternal race (B = 0.77, SE = 0.06, F = 190.12), and marriage (B = 0.42, SE = 0.08, F = 30.08). Random effects for sites and nurses predicted father-visit participation (2.7 & 6.7% of the variance, respectively), even after controlling for population sociodemographic characteristics. These findings suggest that factors operating at the levels of sites and nurses influence father attendance at home visits, even after controlling for differences in populations served. Further inquiry about these influences on father visit attendance is likely to inform program-improvement efforts. PMID:25521707

Improving cervical cancer screening attendance in Finland.  

Science.gov (United States)

High attendance is essential to cervical cancer screening results. Attendance in the Finnish program is currently at 70%, but extensive opportunistic screening occurs beside the organized. A shift from opportunistic to organized screening is imperative to optimize the costs and impact of screening and minimize potential harms. We evaluated the effect of reminder letters (1st reminder) and self-sampling test (2nd reminder) on program attendance. The study population consisted of 31,053 screening invitees in 31 Finnish municipalities. 8,284 non-attendees after one invitation received a reminder letter and 4,536 further non-attendees were offered a self-sampling option. Socioeconomic factors related to participation were clarified by combining screening data to data from Statistics Finland. Reminder letters increased participation from 72.6% (95% CI 72.1, 73.1) to 79.2% (95% CI 78.8, 79.7) and self-sampling further to 82.2% (95% CI 81.8, 82.7). Reminder letters with scheduled appointments resulted in higher increase than open invitations (10 vs. 6%). Screening of original non-attendees increased the yield of CIN3+ lesions by 24%. Non-attendance was associated with young age, immigrant background, lower education level and having never been married. We showed that a total attendance of well over 80% can be achieved within an organized program when the invitational protocol is carefully arranged. PMID:25178683

Effects of ultrafine petrol exhaust particles on cytotoxicity, oxidative stress generation, DNA damage and inflammation in human A549 lung cells and murine RAW 264.7 macrophages.  

Science.gov (United States)

Air pollution has persistently been the major cause of respiratory-related illness and death. Environmental pollutants such as diesel and petrol exhaust particles (PEPs) are the major contributors to urban air pollution. The aim of the present study was to characterize and investigate the in vitro cytotoxicity, oxidative stress, DNA damage and inflammation induced by PEPs. Cultured type II epithelium cells (human A549 lung cells) and alveolar macrophages (murine RAW 264.7 cells) were exposed to control, vehicle control and to different concentrations of PEPs for up to 24h. Each treatment was evaluated by cell viability, cytotoxicity, oxidative stress, DNA damage and inflammatory parameters. Overall in vitro studies demonstrated that both cell lines showed similar patterns in response to the above studies induced by petrol exhaust nanoparticles (PENPs). Vehicle control showed no changes compared with the control. In both cell lines, significant changes at the dose of 20 and 50?g/mL (A549 cell lines) and 10and 20?g/mL (macrophages) for PENPs were found. The reactive oxygen species production in both cell lines shot up in minutes, reached the maximum within an hour and came down after 4h. Hence, exposure to PENPs resulted in dose-dependent toxicity in cultured A549 cells and RAW 264.7 cells and was closely correlated to increased oxidative stress, DNA damage and inflammation.

Attendance at NHS mandatory training sessions.  

Science.gov (United States)

Aim To identify factors that affect NHS healthcare professionals' attendance at mandatory training sessions. Method A quantitative approach was used, with a questionnaire sent to 400 randomly selected participants. A total of 122 responses were received, providing a mix of qualitative and quantitative data. Quantitative data were analysed using statistical methods. Open-ended responses were reviewed using thematic analysis. Findings Clinical staff value mandatory training sessions highly. They are aware of the requirement to keep practice up-to-date and ensure patient safety remains a priority. However, changes to the delivery format of mandatory training sessions are required to enable staff to participate more easily, as staff are often unable to attend. Conclusion The delivery of mandatory training should move from classroom-based sessions into the clinical area to maximise participation. Delivery should be assisted by local 'experts' who are able to customise course content to meet local requirements and the requirements of different staff groups. Improved arrangements to provide staff cover, for those attending training, would enable more staff to attend training sessions. PMID:25669819

Examining Factors Affecting Classroom Attendance and Performance  

Directory of Open Access Journals (Sweden)

Full Text Available

Abstract: This study examined the relationship between four class attitudinal variables and how it affects class attendance and performance. A questionnaire was administered to 134 undergraduate students at medium sized college in Taiwan. The data included questions about the participant’s rating of the level of difficulty of the course (Difficulty, the topics covered in the course (Topics, their motivation towards attending the course (Motivation, and whether or not the participants felt that the course is practical and useful to their future (Practicality. The results of the Pearson correlation coefficients showed that 4 out of the 15 correlations were statistically significant. The negative correlation found between motivation and topics; and practicality and topics suggest the attitude that when choosing courses, students tend to choose courses that they think would easy to pass. The finding that none of the variables were significantly correlated to course attendance and course performance suggests that the strongest predictor of success of a course is based on the student’s level of attendance. This lead to the discussion in the conclusion about pedagogical implications for what teachers can do in their classrooms.

A modelling study of the impact on air quality and health due to the emissions from E85 and petrol fuelled cars in Sweden  

Science.gov (United States)

Alternative fuels are becoming more and more important for road traffic and one fuel that has been used for several years is ethanol (E85). The main discussion points regarding the environmental performance for ethanol as a fuel are related to the production. However, there are also some notable differences in the emissions between E85 and petrol fuelled vehicles. This relates to some extent to the emissions of nitrogen oxides (NOx) and particulate matter (PM) but mainly to the composition of the emitted organic compounds. In the present study two fuel scenarios for passenger cars are investigated for the Västra Götaland Region in Sweden; one where the cars with Otto engines run on petrol and one where they run on E85. Two emission scenarios for 2020 are constructed for the whole Europe and coupled dispersion-chemistry modelling is applied to obtain the population exposure to key pollutants. The differences obtained from the modelling show decreased levels of NOx, ozone and benzene with E85 and increased levels of acetaldehyde in the Västra Götaland Region. For the latter the increase may be up to 80%, while NOx and ozone show decreases of up to a few per cent and a few tenths of per cent, respectively. Exposure to the different air pollutants is calculated as population-weighted concentrations. The health risk assessment, using the calculated exposure and published exposure-response functions for the relevant pollutants, shows decreased health risks in the E85 scenario relative the all-petrol scenario, due to the decreased NOx exposure, correlated with both preterm deaths and asthma. However, NOx (and NO2) may partly be indicators of unmeasured causal exhaust components in the epidemiological studies and thus the exposure-response functions for these may not be applicable in the present case where there is a difference in NOx exposure but not a proportional difference in exposure to other exhaust components normally associated with NOx. Smaller effects are expected from the changes in ozone, acetaldehyde, PM2.5 and benzene exposure. The overall difference is about 1.6 preterm deaths per year for the Västra Götaland Region, with lower values for the E85 scenario, when the uncertain differences due to the differences in NOx exposure are not considered.

The workshop was attended by experts in food technology from industry, government, and academia. Following a general definition of unique space flight requirements, oral presentations were made on state of the art food technology with the objective of using this technology to support the space flight requirements. Numerous areas are identified which in the opinion of the conferees, would have space flight application. But additional effort, evaluation, or testing to include Shuttle inflight testing will be required for the technology to be applied to the Space Station.

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.

Household income and preschool attendance in china.  

Science.gov (United States)

This article draws upon the literature showing the benefits of high-quality preschools on child well-being to explore the role of household income on preschool attendance for a cohort of 3- to 6-year-olds in China using data from the China Health and Nutrition Survey, 1991-2006. Analyses are conducted separately for rural (N = 1,791) and urban (N = 633) settings. Estimates from a probit model with rich controls suggest a positive association between household income per capita and preschool attendance in both settings. A household fixed-effects model, conducted only on the rural sample, finds results similar to, although smaller than, those from the probit estimates. Policy recommendations are discussed.

Web-Server based Student Attendance System using RFIDTechnology  

OpenAIRE

Most educational institutions’ administrators are concerned about student irregular attendance. Truancies can affect student overall academic performance. The conventional method of taking attendance by calling names or signing on paper is very time consuming and insecure, hence inefficient. Therefore, computer based student attendance management system is required to assist the faculty and the lecturer for this time-provide much convenient method to take attendance, but some prerequisites ...

Patient characteristics affecting attendance at general outpatient clinics.  

OpenAIRE

A study was carried out to identify the characteristics of children who do not attend appointments at general outpatient clinics. Over six months, 359 children who had an appointment at a general clinic were studied using a questionnaire given to parents (74% response rate) and by inspection of case notes. Based on their first appointment in the study period, children were divided into 'attenders' (n = 262) and 'non-attenders' (n = 97) for analysis. Non-attenders were significantly more likel...

Exposure to methyl tert-butyl ether and benzene among service station attendants and operators.  

OpenAIRE

Concerns for atmospheric pollution from auto exhaust have led to the blending of "oxygenates" with motor fuels. The most common oxygenate, methyl tert-butyl ether (MTBE) is currently required within several metropolitan areas (Denver and Phoenix) in the range of 12% of the motor fuel. Amendments to the Clean Air Act may expand this requirement to as many as 44 other areas of the United States in the near future. In consideration of the magnitude of potential uncontrolled exposures from its ex...

The reader will also find an answer to the question appearing in a statement by Academician V. P. Mishin: 'It is incomprehensible, but why did we develop two stations in parallel?' This refers to the creation by Chief Designer V. N. Chelomei of the 'Almaz' space complex and, for the first time, refers to Chief Designer N. Bugaiskii - a worker on the 'Almaz' orbital station and one of the main 'perpetrators' in the appearance of the 'Salyuts'.

Predictors and Outcomes of Adolescent Bariatric Support Group Attendance  

Science.gov (United States)

Background Attending support groups connects adults undergoing bariatric surgery to peers and may improve weight loss efficacy. Predictors and outcomes of support group attendance of adolescents undergoing bariatric surgery are unknown. Objective The objective of this cohort study was to determine the rate, predictors, and outcomes of support group attendance in a free-standing adolescent bariatric program. Setting Academic children’s hospital in the U.S. Methods Charts of 68 consecutive adolescents who underwent laparoscopic Roux-en-y gastric bypass or vertical sleeve gastrectomy were retrospectively reviewed, recording demographic and anthropometric variables, support group, and clinic visit attendance. Prospectively collected vitamin adherence data were also analyzed. Univariate analyses evaluated characteristics and multivariate analyses evaluated predictors of support group attendance, clinic visit, and vitamin adherence. Results Of the 68 subjects, one third attended 1–3 support sessions, one third attended ?4, and one third were non-attenders. Greater distance from clinical center (p=0.01) and caregiver bariatric history (p=0.05) were associated with decreased attendance. Only high pre-operative body mass index (BMI) (p < 0.01) and caregiver bariatric history (p < 0.01) were independently associated with decreased attendance. Increased attendance was associated with higher 6 (p=0.03) and 12 month (p<0.01) clinic visit attendance but not with multi-vitamin adherence (p=0.33). Conclusions Caregiver bariatric history and higher pre-operative BMI were associated with decreasing attendance at an adolescent bariatric support group program. This highlights a need to encourage attendance in these patients since adolescent attendance at support group sessions was positively associated with greater adherence to scheduled clinic visits post-operatively which may positively influence long-term outcomes.

The reference stations from EUREF Permanent Network (EPN) in surroundings of Latvia have been used and Bernese GPS Software, Version 5.0, in both static and kinematic modes was applied. The standard data sets were taken from IGS data base. The results of time series have been analysed and distinctive behaviour of daily and subdaily movements of EUPOS®-Riga and LatPos stations was identified. The reasons of dependence of GNSS station coordinate distribution on possible external factors such as seismic activity of some areas of Latvia and periodic processes were given.

Waste Transfer Stations  

DEFF Research Database (Denmark)

tion and transport is usually the most costly part of any waste management system; and when waste is transported over a considerable distance or for a long time, transferring the waste from the collection vehicles to more efficient transportation may be economically beneficial. 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 describes the main features of waste transfer stations, including some considerations about the economical aspects on when transfer is advisable.

Defining frequent attendance in general practice  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background General practitioners (GPs or researchers sometimes need to identify frequent attenders (FAs in order to screen them for unidentified problems and to test specific interventions. We wanted to assess different methods for selecting FAs to identify the most feasible and effective one for use in a general (group practice. Methods In the second Dutch National Survey of General Practice, data were collected on 375 899 persons registered with 104 practices. Frequent attendance is defined as the top 3% and 10% of enlisted patients in each one-year age-sex group measured during the study year. We used these two selections as our reference standard. We also selected the top 3% and 10% FAs (90 and 97 percentile based on four selection methods of diminishing preciseness. We compared the test characteristics of these four methods. Results Of all enlisted patients, 24 % did not consult the practice during the study year. The mean number of contacts in the top 10% FAs increased in men from 5.8 (age 15–24 years to 17.5 (age 64–75 years and in women from 9.7 to 19.8. In the top 3% of FAs, contacts increased in men from 9.2 to 24.5 and in women from 14 to 27.8. The selection of FAs becomes more precise when smaller age classes are used. All selection methods show acceptable results (kappa 0.849 – 0.942 except the three group method. Conclusion To correctly identify frequent attenders in general practice, we recommend dividing patients into at least three age groups per sex.

Dual Keel Space Station  

Science.gov (United States)

In response to President Reagan's directive to NASA to develop a permanent marned Space Station within a decade, part of the State of the Union message to Congress on January 25, 1984, NASA and the Administration adopted a phased approach to Station development. This approach provided an initial capability at reduced costs, to be followed by an enhanced Space Station capability in the future. This illustration depicts a configuration with enhanced capabilities. It builds on the horizontal boom and module pattern of the revised baseline. This configuration would feature dual keels, two vertical spines 105-meters long joined by upper and lower booms. The structure carrying the modules would become a transverse boom of a basically rectangular structure. The two new booms, 45-meters in length, would provide extensive accommodations for attached payloads, and would offer a wide field of view. Power would be increased significantly, with the addition if a 50-kW solar dynamic power system.

Decommissioning nuclear power stations  

International Nuclear Information System (INIS)

The main objective of research at Berkeley Nuclear Laboratories into the decommissioning of nuclear power stations is to assess the safety implications of the various strategies which are being considered worldwide for the eventual dismantling of these stations. Although the BNL studies have primarily addressed the oldest of the CEGB's plant, the steel pressure vessel Magnox reactors, assessments of PWR decommissioning have also been undertaken to allow design changes to be introduced which will reduce eventual dismantling problems and minimise the production of radioactive waste.

Attending to music decreases inattentional blindness.  

Science.gov (United States)

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. PMID:21555226

Ozone toxicity symptoms among flight attendants.  

Science.gov (United States)

Because of persistent complaints of ozone-toxicity type symptoms among crew members of commercial airlines, we undertook a survey to determine the extent of the problem and the associated flight factors. Self-reported questionnaires and flight diaries were completed by 1,330 flight attendants, (FAs) working for three different airlines. Ozone-toxicity type symptoms were reported three or four times more frequently by FAs with airlines flying at high altitudes than by those with low-flying airlines. When examined by characteristics of flights, the ozone-toxicity type symptoms were significantly associated with flight altitude, duration and type of aircraft, but not with years worked, sex, medical history, or home residence. Other symptoms indicative of fatigue or stress were mainly associated with flight duration. While these indirect data cannot implicate ozone specifically, they offer evidence that ozone-related health problems do exist among a large proportion of FAs. PMID:7342754

Attendance and Achievement in Medicine: Investigating the Impact of Attendance Policies on Academic Performance of Medical Students  

Science.gov (United States)

Background: The attendance mandate for the medical course in Melaka Manipal Medical College, Manipal, India was increased from 75% to 90% based on the assumption that the mandatory increase will improve the students’ performance. Aims: To find out whether there is any correlation between class attendance and academic performance. Subjects and Methods: This was an institution based retrospective analytical study. Students who have completed Phase I (first two and a half years) of the MBBS course were included in the study. Student marks and attendance, from the database were obtained from three random batches, each, from two clusters A and B respectively. Those who had a mandatory attendance requirement of 75% belonged to A (n = 243), and those who had a mandatory attendance percentage of 90% belonged to B (n = 360). Statistical analyses performed included, Pearson 2 tailed correlation to correlate class attendance with student performance; Cluster analysis to classify group average in a similarity matrix; t-test to determine significance of difference in percentage of students who attained 100% when the college changed mandatory attendance from 75% to 90%; Mann–Whitney test to find out if there was a better performance in university exam when attendance policy changed. Results: There was a significant correlation between attendance and the students who passed in the University exam. The number of students in the pass category was maximum (>90%) compared to students in distinction and failed categories. Percentage of students with 100% attendance rose from 4% (n = 10) to 11% (n = 40) when the mandatory attendance was increased from 75% to 90%. Conclusions: Attendance policy correlated with better academic performance. Reducing absenteeism, probably contributed to the improved academic performance of the students. But the link between attendance and best and worst performances could not be predicted because of small numbers in every batch. PMID:23919190

The trend of the total stock of the private car-petrol in Spain: Stochastic modelling using a new gamma diffusion process  

International Nuclear Information System (INIS)

The main aim of this study is to model the trend of the evolution of the total stock of private petrol-driven cars. In Spain, as in other EU countries, this trend between 2000 and 2005 differed significantly from that observed from 1986 to 1999. Moreover, it varies greatly from that corresponding to the stock of diesel-driven cars, which consistently presents an exponential Gompertz-type increase. Spain constitutes a typical example of a failure to observe the maximum CO2 emission levels assigned to it by 2012 under the Kyoto Protocol (1992); a significant percentage of these excess emissions is accounted for by the land transport sector, in general, and by the private cars subsector, in particular. This paper proposes a stochastic model based on a new non homogeneous stochastic gamma-type diffusion process which it is a stochastic version of a Gamma function type deterministic growth model considered in Skiadas . We describe its main probabilistic characteristics and establish a statistical methodology by which it can be fitted to real data and obtain medium-term forecasts that, in statistical terms, are quite accurate

Kiowa Creek Switching Station  

Energy Technology Data Exchange (ETDEWEB)

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.

The design, operation, and economics of the Pickering generating station are described. Pickering A comprises four 508MW(e) units and is based on the Candu system of heavy water moderated, pressurised heavy water cooled, uranium dioxide fueled, horizontal pressure tube reactor. Brief details are given of station layout and principle design parameters. Safety features are described and a brief account is given of scheduling, construction and commissioning. Operating performance is discussed. Turbine generators and auxiliaries, and the feedwater system contributed to more than half the outage time. An illustration is given of incorrect rolling operation which caused cracks in the Zr-Nb pressure tube, resulting in several leaks in Unit 3. Heavy water losses were low, as were radioactive releases. Economic features are discussed in terms of capital cost operating costs and total unit energy cost. Reference is made to Pickering B which is a 4 x 540MW(e) station, a mirror image of Pickering A, and scheduled for operation in 1980. The interest in the Pickering station being shown in many areas of the world is attributed to its simplicity, low fuel cycle cost, versatile pressure tube design features which meet requirements for safety, reliability, and maintainability.

[Reply to “Space Station?” by L. H. Meredith] Way station  

Science.gov (United States)

I agree with Les Meredith's statement of valid and nonvalid objectives for the space station. The problem with the space station that NASA is proposing is that it is designed to a nonvalid objective, specifically microgravity experimentation. I would support a space station that addressed the valid objective of a way station, but I cannot support NASA's current design.Meredith states that the space station can only be justified as a political action by the United States to reassert its preeminence in space. Meredith lists a valid objective of creating a permanent manned presence to provide a “way station” for future Earth orbital activities and Solar System exploration. Meredith further argues that two other classes of space station objectives, namely a microgravity research and manufacturing facility and an Earth and astronomical remote sensing platform, are not valid because those activities can be better carried out by non-space station means.

The duty health physicist program at Byron Nuclear Power Station  

International Nuclear Information System (INIS)

The Duty Health Physicist Program at Byron Station was established to deal with routine health physics tasks and provide an interface between frontline and upper radiation-chemistry management. The program consists of a weekly rotation of selected members of the health physics staff into the duty health physicist position to handle the assigned duty tasks. The tasks include, but are not limited to, daily isotopic and air sample review, effluent release package review, maximum permissible concentration calculations, dose approvals, as-low-as-reasonably-achievable action review of pending jobs, and general availability to answer questions and address problems in health-physics-related areas of plant operation. The daily attendance of the duty health physicist at the radiation-chemistry and station plan-of-the-day meetings has increased the overall presence and visibility of the health physics program to upper station management and other station departments. Since its inception in July of 1985, the Duty Health Physics Program has been a major contributor to the observed 50% reduction in reportable personnel errors in the radiation-chemistry department (based on personnel-error-related deviation reports and license event reports generated on the radiation-chemistry department at Byron Station). Although difficulty to quantify, other important benefits of this program are also discussed in this paper

Portable Fingerprint-Based Attendance Recording & Monitoring System?  

Directory of Open Access Journals (Sweden)

Full Text Available This paper presented the development of a portable attendance monitoring system based on fingerprint identification that can be used by lecturers to monitor attendance of students. Fingerprint-based identification is one of the oldest method among all biometric or security techniques which has been successfully used in numerous applications. Every person has unique, immutable fingerprints. A fingerprint is made of a series of ridges and furrows on the surface of the finger. The distinctiveness of a fingerprint can be determined by the pattern of ridges and furrows as well as the minutiae points. Minutiae points are local ridge characteristics that occur at either a ridge bifurcation or a ridge ending. A portable fingerprint scanner has been utilized as the input to acquire fingerprint images and a laptop equipped with attendance recording and monitoring software as a mobile terminal to process the fingerprint images and record the attendance. This system can be used by lecturers to replace the old method of attendance recording, so that the integrity of the attendance record can be upheld. The actual student’s attendance can be recorded and stored in database. The system is also capable of processing the record to determine students who do not fulfil the attendance percentage requirement.

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.

Shippingport station communications program  

International Nuclear Information System (INIS)

The author discusses how the communications program for the Shippingport Atomic Power Station has a long history. It can be traced as far back as 1953, when the U.S. Atomic Energy Commission (AEC) awarded a contract to Westinghouse Electric to design the nuclear portion of a power plant for electric utility use. During May of the next year, President Eisenhower initiated groundbreaking ceremonies for the construction of the commercial atomic power plant at Shippingport, Pennsylvania

Microscope Imaging Station  

Science.gov (United States)

The Exploratorium in San Francisco continue to break new and intriguing ground with their latest online project, the Microscope Imaging Station. The actual physical Station resides at their museum, and was opened in 2004. Developed to complement this interactive exhibit, this online manifestation of the Station allows visitors to peer into the cells of living organisms such as sea urchins and zebrafish. The sea urchin feature is a real treat, as it is accompanied by a well-written essay on how this spiky creature may help unlock the secrets of genes, reproduction, and cancer. If that wasn't enough, the essay (as with other features on the site) includes a short video clip. The "Gallery" is definitely worth a stop as well. Here, visitors will find a wide range of high-resolution images and movies created with research-grade microscopes. Watching cells move, the fertilization process and the world of mitosis is a rather nice way to spend a few minutes, and visitors will probably want to pass the site along to friends and family.

Mars Desert Research Station  

Science.gov (United States)

The Mars Desert Research Station (MDRS) located in southern Utah presents an invaluable opportunity for researchers to become personally involved in the quest for the human exploration of Mars. MDRS is owned and operated by the Mars Society. Crews from across the nation and around the globe rotate in every two weeks to do a simulation of a human crew on Mars. The location and nature of the Mars Desert Research Station provide a unique opportunity for scientists from the Southwest to propose and do research pertaining to the human exploration of Mars. Being the closest major university to the research station, Brigham Young University has become a worthy asset to the Mars Society in their long-term goals for MDRS. The Mars Research Group at Brigham Young University has spent the past nine months proving their usefulness by making four trips down to the habitat to provide support whenever needed. In the upcoming year we plan to finish modifications on the habitat's greenhouse, get the habitat's new 14-inch telescope running, and provide technical briefings for incoming crews on the use of the habitat, greenhouse, and telescope.

Attendance in cancer screening programmes in Italy  

Directory of Open Access Journals (Sweden)

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/Insular Italy. Similar geographical distributions can be noted in the attendance rates (60.5% in the North of Italy, 56% in the Central area and 38.3% in the South of Italy. Cervical cancer screening: From the data obtained by the 2006 survey, 93.5% of theoretical extension was registered in the Centre of Italy, 65% in the North and 65.5% or in the South of Italy. 38.5% of invited women underwent a Pap-test. A decreasing trend in participation can be observed from Northern (45.6% to Central (35.7%, and to Southern (28.7% Italy. Colorectal cancer screening: In 2006, theoretical extension of colorectal cancer screening in Italy was 44%, with significant differences in geographical distribution (66.1% in the North of Italy 48.5% in the Centre and about 10% in the South of our country. About 907,000 people had a faecal occult blood test in 2006 (adjusted compliance of 44.6%. Data from the survey “Multiscopo sulle famiglie” showed that organised screening activity can reduce social inequalities of access to cancer screening, increasing screening utilization particularly in less educated people.

Conclusions: Organised cancer screening programmes have been extended in recent years, improving the equity in the access to early diagnosis for the people invited. However, social and geographical inequalities still remain.

Factors Associated with Attendance and Non-Attendance of Support Groups among HIV Positive Adults Attending an Antiretroviral Community Clinic at Ekurhuleni District, South Africa  

Directory of Open Access Journals (Sweden)

Full Text Available Health care facilities providing antiretroviral treatment (ART to HIV positive people have seen a decline in the uptake and use of HIV support groups. A cross sectional survey was conducted to 1 determine the characteristics of HIV positive people who have and who have not attended support groups; 2 determine factors associated with attendance of support groups; and 3 investigate perceived barriers to participate in support groups among HIV positive adults attending an ART clinic in Gauteng, South Africa. The total samples included 248 HIV positive adults and the highest proportion were females (n = 156, 62.9%. The mean age of the participants was 34.2 years, (range 18 to 56 years. Almost two thirds (n = 144, 58.1% had never attended support groups. Participants who attended support groups were more likely to be older than non-attenders (OR = 1.04, CI: 1.01 - 1.07, more likely to be taking ART medication (OR = 1.64, CI: 1.00 - 2.65 and more likely to have known of their HIV diagnosis for a longer time (OR = 2.20, CI: 1.42 - 3.40. Employed participants were less likely to attend support groups than unemployed participants (OR = 0.47, CI: 0.27 - 0.80. Concerns for privacy and confidentiality in support groups, and fear of stigma and discrimination were the key barriers to participate in support groups. Participants also perceived support groups as a service for people who could not cope with their HIV diagnosis. Health care providers who plan to start support groups should take into consideration issues of support group size, confidentiality, and timing for support group meetings. It is imperative that education on the benefits of HIV support groups forms a primary component of routine counselling for PLWHI.

This concerns power plants (including nuclear power stations) and it is proposed to replace steam as working medium by ammonia. Condensation problems shall be solved by using an auxiliary medium (e.g. H2O or salts like ZnCl2(NH3)2 or ZN(NH3)4(ReO4)2). The working medium dissolves in the auxiliary medium, and when required it is evaporated at different places of the plant where it is used or reabsorbed in the auxiliary medium. The proposed plant is described in principle only, some variants are discussed supported by tables and diagrams. (UWI)

Power station chemistry  

International Nuclear Information System (INIS)

The increasing contribution of power station chemistry to new methods of operation, which is partly due to the increased use of fossil fuels and partly due to the greater consideration given to the protection of the environment, is irreversible. This is even more valid in the case of chemical procedures which have recently found or will soon find application in power plant technology. Coal conversion and gasification, desulphurization of flue gases, reduction of NOsub(x) emissions, improvements in dust collection, utilization of power plant by-products and also problems with deposition and effluent treatment can be quoted as examples.

Dubna international experimental station  

Science.gov (United States)

Earth station equipment and techniques used to establish earth-to-satellite links at frequencies over 10 GHz for the Intercosmos program are detailed. The station was built at Dubna in the U.S.S.R., and featured three sites within 12 km from one another. The first site has 12 and 3 m antennas, a 30 m mast for test lines at 11, 20, and 30 GHz, radiometers for measuring sky noise, and computers. A second site has a 24 m mast for tests at 20 and 30 GHz, and a boresight system. The third site has a 30 m mast, transmission equipment for the 11, 20, and 30 GHz bands, and meteorological equipment. Data exchange between sites is accomplished by a telephone link through the Statsionar-4 satellite. The mast antennas are used for transmission and reception of signals, television signals, and voice data. Antenna pointing is achieved by means of electron scanning or a discrete pointing system, automatically or manually. Test links are set up at 12 and 1 km distance to test attenuation in each of the frequencies. The computers store 72 hr of data in buffer and then transfer it to long-term drum memory.

Data from 70 classes and 1829 students over a period of 15 years were analyzed. Grade and attendance differences were analyzed for five different seating configurations: by row, by column, the front of the room versus the back of the room, the center of the room versus the perimeter of the room, and the middle of the room versus the sides of the room. Results utilizing numeric percentage grades and attendance percentages indicated students sitting in the more central parts of the class had higher percentage grades and attended classes more frequently than those students sitting in the less central parts of the class. Women attended class more frequently than men, yet there were no sex differences on grades. PMID:21117484

Improving attendance in psychiatric outpatient clinics by using reminders.  

Science.gov (United States)

We compared non-attendance rates at follow-up appointments in an adult psychiatry outpatient clinic using three different reminder methods: letters, telephone prompts and text message reminders. Two of the three strategies resulted in a significant increase in the rate of attendance. Reminder letters increased attendance from 62% to 85% (Prate was not significantly different between the two groups when telephone reminders were used (P=0.068). However, telephone prompts resulted in an 8% higher cancellation rate compared to controls. When all factors were taken into consideration, no method demonstrated clear superiority. Efforts should be made to reduce patient non-attendance, as this is a predictor of patients being unwell and at higher risk of relapse. Text messages are an inexpensive method of reminding patients, although appropriate safeguards for patient confidentiality are required. PMID:25316039

Spatial Analysis of Skilled Birth Attendant Utilization in Ghana  

Directory of Open Access Journals (Sweden)

Full Text Available Background: Maternal mortality is a major health problem in most resource-poor settings, especially in sub-Saharan Africa. In Ghana, maternal mortality remains high and births attended by skilled health professionals are still low despite the introduction, in 2005, of free maternal health care for all women seeking care in public health facilities. Objectives: This study aimed to explore geographical patterns in the risk of not utilizing a skilled birth attendant during childbirth in women of different socioeconomic backgrounds in Ghana. Methods: Global and Geographically Weighted Odds Ratios (GWORs were used to examine the spatially varying relationships between low socioeconomic status (low education and low income and non-utilization of skilled birth attendants based on data from the Ghana Demographic and Health Survey (GDHS 2008. Results: Low education and low income were associated with non-use of skilled birth attendants. The GWORs revealed a north-south spatial variation in the magnitude of the association between non-use of skilled birth attendants and low education (Log GWOR ranged from 0.75 to 9.26 or low income (Log GWOR ranged from 1.11 to 6.34 with higher values in the north. Conclusions: The relationship between low socioeconomic status and the non-use of skilled birth attendants in Ghana is geographically variable. Effective governmental and non-governmental interventions are needed to address these regional inequalities.

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

Science.gov (United States)

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 those tested in August, which suggested that mileage was the key criterion of car performance on the basis of elemental emission factors.

SMART Station Blackout Analysis  

Energy Technology Data Exchange (ETDEWEB)

The Fukushima accident represents the latest fear of any nuclear industry whether established or just starting. Although it was a natural disaster, it must be assured that even under such circumstances, radioactive material is contained and release is avoided. Despite the possibility of radioactive release occurring over multiple consequences, such scenarios must be considered. The Fukushima scenario is considered in the SMART (System Integrated Modular Advanced Reactor) design with the availability and loss of the Passive Residual Heat Removal System (PRHRS). Using the Multi-dimensional Analysis of Reactor Safety (MARS) code, this paper presents the Fukushima scenario studies along with the calculated grace time as results. The results of SMART Station Black Out (SBO) analysis show grace time of almost two and a half days for the worst-case scenario.

Rationales for attending or not attending mammography screening--a focus group study among women in Sweden.  

Science.gov (United States)

Quantitative findings regarding factors that affect attendance in population-based outreach mammography programmes need to be complemented by descriptive data. The aim of this study was to obtain descriptive insights into the meanings that Swedish women attach to mammograms and their rationales for attending or not attending mammography screening. For this purpose a total of 31 women were recruited to eight focus group discussions. Through inductive analysis, six main themes were identified as important issues in reasoning about attendance or non-attendance in mammography screening: negative experiences, perceived risk factors, knowledge of one's own body, perceived problems with mammography, political, ideological and moral reasoning, and involuntary non-attendance, due to the inability of the screening programme to cover some women (e.g. those with breast implants). In conclusion, there is a need to reinforce the information that mammography is an examination aiming at detecting lumps at an asymptomatic stage. However, the nature and amount of information the women themselves desire is inconsistent. Furthermore, the personal encounter between the individual woman and the staff seems to be of particular importance. An improved dialogue appears an attractive way of adapting the screening situation to meet the varied needs and expectations of the women who are invited. PMID:11711758

Factors influencing patients' continuing attendance at a given dentist.  

Science.gov (United States)

AimIt is the aim of this paper to consider the factors associated with a patient's continuing attendance at a particular dentist's surgery.MethodsA data set was established consisting of General Dental Services' (GDS) patients whose birthdays were included within a set of randomly selected dates, 20 in each possible year of birth. The data set was restricted to those patients aged 18 or older in 2003 who attended only one dentist in only one postcode area in 2003, and who also attended only one dentist in the same postcode area in 2005, and where the dentist attended in 2003 was also practising in the same postcode area in 2005. The patients were classified by age, gender and charge-paying status, and by whether they had attended a GDS dentist in 2002, and the dentists attended in 2003 were classified by age and gender. The proportion of patients changing dentists between 2003 and 2005 was calculated, together with standard error (se), for each combination of these factors. This was then replicated for each year from 1993-2002.ResultsData for 323,382 patients were included in the analysis for 2003, these patients having not changed address during a two-year period, nor had their dentist changed location. The proportion of patients changing dentist over the period 2003 and 2005 was 15.5% (se 0.06 PCT). This has increased steadily since 1993, when the proportion was 12.4%.ConclusionsFactors influencing whether a patient changes dentist include patient age and charge paying status, dentist age and gender, and the patient's previous attendance pattern.

Geophysical Monitoring Station (GEMS)  

Science.gov (United States)

GEMS (GEophysical Monitoring Station) is one of three missions undergoing Phase A development for possible selection by NASA's Discovery Program. If selected, GEMS will perform the first comprehensive surface-based geophysical investigation of Mars, filling a longstanding gap in the scientific exploration of the solar system. It will illuminate the fundamental processes of terrestrial planet formation and evolution, providing unique and critical information about the initial accretion of the planet, the formation and differentiation of the core and crust, and the subsequent evolution of the interior. The scientific goals of GEMS are to understand the formation and evolution of terrestrial planets through investigation of the interior structure and processes of Mars and to determine its present level of tectonic activity and impact flux. A straightforward set of scientific objectives address these goals: 1) Determine the size, composition and physical state of the core; 2) Determine the thickness and structure of the crust; 3) Determine the composition and structure of the mantle; 4) Determine the thermal state of the interior; 5) Measure the rate and distribution of internal seismic activity; and 6) Measure the rate of impacts on the surface. To accomplish these objectives, GEMS carries a tightly-focused payload consisting of 3 investigations: 1) SEIS, a 6-component, very-broad-band seismometer, with careful thermal compensation/control and a sensitivity comparable to the best terrestrial instruments across a frequency range of 1 mHz to 50 Hz; 2) HP3 (Heat Flow and Physical Properties Package), an instrumented self-penetrating mole system that trails a string of temperature sensors to measure the thermal gradient and conductivity of the upper several meters, and thus the planetary heat flux; and 3) RISE (Rotation and Interior Structure Experiment), which would use the spacecraft X-band communication system to provide precision tracking for planetary dynamical studies. The two instruments are moved from the lander deck to the martian surface by an Instrument Deployment Arm, with an appropriate location identified using an Instrument Deployment Camera. In order to ensure low risk within the tight Discovery cost limits, GEMS reuses the successful Lockheed Martin Phoenix spacecraft design, with a cruise and EDL system that has demonstrated capability for safe landing on Mars with well-understood costs. To take full advantage of this approach, all science requirements (such as instrument mass and power, landing site, and downlinked data volume) strictly conform to existing, demonstrated capabilities of the spacecraft and mission system. It is widely believed that multiple landers making simultaneous measurements (a network) are required to address the objectives for understanding terrestrial planet interiors. Nonetheless, comprehensive measurements from a single geophysical station are extremely valuable, because observations constraining the structure and processes of the deep interior of Mars are virtually nonexistent. GEMS would utilize sophisticated analysis techniques specific to single-station measurements to determine crustal thickness, mantle structure, core state and size, and heat flow, providing our first real look deep beneath the surface of Mars.

Exploring the school attendance of children with epilepsy  

Directory of Open Access Journals (Sweden)

Full Text Available The childhood epilepsy is a chronic disease that can have an impact in various spheres of life of the child, including academic performance and school attendance. This study aimed to describe and compare the school attendance of children with epilepsy who attend mainstream and special schools. Participants were 56 children aged between 7 and 14 years who attended regular or special schools located in two Brazilian cities of medium size. To collect the information we used two instruments: Data sheet of identification and characterization of the child and Data sheet to record the attendance school. The results showed that children in special schools had higher rates of absenteeism compared to students in regular schools. Additionally, we observed that these children use more drugs and have implications on health more severe than children in regular schools. Thus, it is the childhood epilepsy as a disease complex that brings substantial effects on various areas of children’s lives by reinforcing the need for studies that might expand the knowledge to and the experiences associated with the education of these children.

Elementary school nurse interventions: attendance and health outcomes.  

Science.gov (United States)

Regular school attendance is a necessary part of the learning process; student absenteeism has a direct association with poor academic performance. School nurses can influence student attendance. This study describes the impact of school nurse interventions on student absenteeism and student health. A retrospective review of 240 randomly selected elementary student health folders and attendance records was conducted. School nurses were involved with 75% of high-absence students as compared to 66% of low-absence students; they were also more involved with students who had previously identified health conditions. There were no referrals to the school nurse for absenteeism and school nurse interventions were not targeted to attendance, despite 17% of students missing 11 or more school days. Nursing documentation was sparse and primarily task related. Few records contained entries of nursing diagnoses, interventions, or outcomes. Of the 134 interventions provided, only 56 (41.2%) had some information about the condition outcome, but it was insufficient to determine the effectiveness of nursing interventions. Furthermore, the record system did not support the collection of standard information for interventions or outcomes from which effectiveness could be determined. Recommendations include establishment of an attendance referral policy and improved documentation systems, including the use of standardized nursing language to demonstrate student outcomes.

Accelerated GLAS exposure station  

International Nuclear Information System (INIS)

The Geoscience Laser Altimeter System (GLAS) is being developed by NASA/GSFC to measure the dynamics of the ice sheet mass balance, land, and cloud and atmospheric properties. An instrument altimetric resolution of 10 cm per shot is required. The laser transmitter will be a diode pumped, Q-switched, Nd:YAG laser producing 1064 nm, 100 mJ, 4 ns pulses at 40 Hz repetition rate in a TEM? mode. A minimum lifetime goal of 2 billion shots is required per laser transmitter. The performance of the GLAS laser can be limited by physical damage to the optical components caused by the interaction of intense laser energy with the optical coatings and substrates. Very little data exists describing the effects of long duration laser exposure, of 4 ns pulses, on an optical component. An Accelerated GLAS Exposure Station (AGES) is being developed which will autonomously operate and monitor the GLAS laser at an accelerated rate of 500 Hz. The effects of a large number of laser shots will be recorded. Parameters to be monitored include: laser power, pulsewidth, beam size, laser diode drive current and power, Q-switch drive voltage, temperature, and humidity. For comparison, one set of AGES-sister optical components will be used in the non-accelerated GLAS laser and another will be evaluated by a commercial optical damage test facility

Shippingport station communications program  

International Nuclear Information System (INIS)

At the Shippingport Station Decommissioning Project, the central idea of the communications program that was developed for use was purposely designed to be as uncomplicated as possible. The central theme, that was developed and communicated, is that all nuclear plants will someday need to be retired and also decommissioned. The Shippingport Plant, originally constructed as a demonstration nuclear power plant, was now being decommissioned as a demonstration to the world-wide nuclear industry that this evolution can be done in a safe and cost-effective manner. Furthermore, the technology currently exists to complete this process. The new phase of the communications program was initiated even before the responsibility for the plant was transferred from Duquesne Light to GE. With such a change forthcoming, it was necessary to inform local officials of these plans, and the reasons for them. Equally important was the need to inform a variety of agencies and offices in the three-state area of the changes, and the continuing need to involve them in the Site Emergency Plan. This document was also revised in recognition of changing site conditions, as well as the changes in responsibility. 1 ref

Impact of Learners on Emergency Medicine Attending Physician Productivity  

Directory of Open Access Journals (Sweden)

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 1.97,2.00. Compared with attending physician with no learner, attending physicians with a resident saw more PPH (1.99 vs 1.87, p< 0.005. There was no statistically significant difference found between EM1: 1.98PPH, EM2: 1.99PPH, EM3: 1.99PPH, and off-service rotators: 1.99PPH. Conclusion: EM attending physicians paired with a resident in a one-on-one teaching model saw statistically significantly more patients per hour (0.12 more patients per hour than EM attending physicians alone. EM attending physicians paired with a medical student saw the same number of patients per hour compared with working alone. [West J Emerg Med. 2014;15(1:41–44.

On the Predictability of Talk Attendance at Academic Conferences  

CERN Document Server

This paper focuses on the prediction of real-world talk attendances at academic conferences with respect to different influence factors. We study the predictability of talk attendances using real-world tracked face-to-face contacts. Furthermore, we investigate and discuss the predictive power of user interests extracted from the users' previous publications. We apply Hybrid Rooted PageRank, a state-of-the-art unsupervised machine learning method that combines information from different sources. Using this method, we analyze and discuss the predictive power of contact and interest networks separately and in combination. We find that contact and similarity networks achieve comparable results, and that combinations of different networks can only to a limited extend help to improve the prediction quality. For our experiments, we analyze the predictability of talk attendance at the ACM Conference on Hypertext and Hypermedia 2011 collected using the conference management system Conferator.

Student and Teacher Attendance: The Role of Shared Goods in Reducing Absenteeism  

DEFF Research Database (Denmark)

A theoretical model is advanced that demonstrates that, if teacher and student attendance generate a shared good, then teacher and student attendance will be mutually reinforcing. Using data from the Northwest Frontier Province of Pakistan, empirical evidence supporting that proposition is advanced. Controlling for the endogeneity of teacher and student attendance, the most powerful factor raising teacher attendance is the attendance of the children in the school, and the most important factor influencing child attendance is the presence of the teacher. The results suggest that one important avenue to be explored in developing policies to reduce teacher absenteeism is to focus on raising the attendance of children.

Controversial power station  

International Nuclear Information System (INIS)

When information on plans to build a power station in Trebisov first appeared reactions differed. A 40-billion investment in a town with more than 20% unemployment seemed attractive. But some people did not like the idea of having a power plant located in the town. Around one year after the investment was officially announced TREND returned to Trebisov. In the meantime the investor has managed to overcome one of the biggest obstacles on its way to building a new power plant. The ministry responsible gave the environmental study a positive rating. But objectors are still not sure that everything is fine. They claim that the study misinterprets data and that the ministry did not show expertise when evaluating it. 'Is it possible that a coal power plant located in a town would have twice as many positive effects on peoples' health than negative ones? Why don't we build them everywhere?'asked the chairman of the civic society, Trebisov nahlas, Gejza Gore. The developer of the project, Ceskoslovenska energeticka spolocnost (CES), Kosice is fighting back and claims that their counterpart lacks professional arguments. In the meantime it is preparing for area management proceedings. Trebisov is also involved in the discussion and claims that the town planning scheme does not include such a project. The Ministry of Construction has a different opinion. In the opinion of the Ministry the town planning scheme allows a 885-megawatt power plant to be built only a few hundred meterplant to be built only a few hundred meters away from housing estates.

Attitude towards alcohol, church attendance and denominational identity.  

Science.gov (United States)

This paper describes the development of a 16-item Likert scale of attitude towards alcohol. Data derived from 315 individuals, concerned with various forms of youth work in England, demonstrate that both denominational affiliation and frequency of church attendance are significant determinants of attitudes towards alcohol. Membership of the Free Churches and frequent church attendance are associated with less liberal attitudes. These conclusions are discussed against the background of previous discrepant findings relating religiosity with alcohol use and abuse and contemporary sociological theories regarding the compartmentalisation of religious beliefs.

The last decades have witnessed a growing interest in electric vehicles (EV) as an integral part of the vision for sustainable regions. The main reasons include the acknowledgment of the necessity of auto-mobility, the technological advancements of electric vehicles, and the interest in petrol-free, low-emission vehicles due to the rising oil prices and global warming. Adequate on-road EV recharging infrastructure is essential in the transformation of EV into a practical transport option and the wide-scale market penetration of EV. Nevertheless, the efficient spatial distribution of EV recharging is rarely explored. current study focuses on assessing the demand driven need for on-road EV recharging stations, and finding their efficient spatial distribution, while accounting for economic, social, environmental and land-use considerations. The analysis, conducted for Demark, consists of four steps. Firstly, the demand for on-road recharging of EV’s based on the national travel demand patterns is evaluated, while considering the existence of a city-wide slow recharging network. Secondly, the Edison model for the optimal deployment of EV recharging stations is applied. The model evaluates the need for recharging at the vehicle level, and seeks the optimal deployment of recharging stations on the basis of the distribution of the potential recharging points and the inventory of candidate sites. Thirdly, the EV market share is evaluated as a function of the number of EV recharging stations by employing a discrete choice model, estimated on the basis of a stated preference survey. Last, the feasibility of the optimal EV spatial distribution of the EV charging stations is analyzed, based on the Danish official socio-economic framework (TERESA). Results show: (i) the number of required recharging stations for satisfying the travel demand, (ii) the optimal deployment of recharging stations, (iii) the change in travel patterns due to detours for EV recharging, (iv) the feasibility of the proposed infrastructure while considering economic costs and benefits for operators and users, impact on government budget as well as environmental externalities, namely pollutant emissions, carbon footprint, and noise exposure. The results demonstrate the applicability and feasibility of the proposed method for planning an EV recharging network in sustainable regions.

ANSS Backbone Station Quality Assessment  

Science.gov (United States)

In this study we assess the ambient noise levels of the broadband seismic stations within the United States Geological Survey's (USGS) Advanced National Seismic System (ANSS) backbone network. The backbone consists of stations operated by the USGS as well as several regional network stations operated by universities. We also assess the improved detection capability of the network due to the installation of 13 additional backbone stations and the upgrade of 26 existing stations funded by the Earthscope initiative. This assessment makes use of probability density functions (PDF) of power spectral densities (PSD) (after McNamara and Buland, 2004) computed by a continuous noise monitoring system developed by the USGS- ANSS and the Incorporated Research Institutions in Seismology (IRIS) Data Management Center (DMC). We compute the median and mode of the PDF distribution and rank the stations relative to the Peterson Low noise model (LNM) (Peterson, 1993) for 11 different period bands. The power of the method lies in the fact that there is no need to screen the data for system transients, earthquakes or general data artifacts since they map into a background probability level. Previous studies have shown that most regional stations, instrumented with short period or extended short period instruments, have a higher noise level in all period bands while stations in the US network have lower noise levels at short periods (0.0625-8.0 seconds), high frequencies (8.0- 0.125Hz). The overall network is evaluated with respect to accomplishing the design goals set for the USArray/ANSS backbone project which were intended to increase broadband performance for the national monitoring network.

Hey] What's Space Station Freedom?  

Science.gov (United States)

This video, 'Hey] What's Space Station Freedom?', has been produced as a classroom tool geared toward middle school children. There are three segments to this video. Segment One is a message to teachers presented by Dr. Jeannine Duane, New Jersey, 'Teacher in Space'. Segment Two is a brief Social Studies section and features a series of Presidential Announcements by President John F. Kennedy (May 1961), President Ronald Reagan (July 1982), and President George Bush (July 1989). These historical announcements are speeches concerning the present and future objectives of the United States' space programs. In the last segment, Charlie Walker, former Space Shuttle astronaut, teaches a group of middle school children, through models, computer animation, and actual footage, what Space Station Freedom is, who is involved in its construction, how it is to be built, what each of the modules on the station is for, and how long and in what sequence this construction will occur. There is a brief animation segment where, through the use of cartoons, the children fly up to Space Station Freedom as astronauts, perform several experiments and are given a tour of the station, and fly back to Earth. Space Station Freedom will take four years to build and will have three lab modules, one from ESA and another from Japan, and one habitation module for the astronauts to live in.

The occupational health and safety of flight attendants.  

Science.gov (United States)

In order to perform safety-critical roles in emergency situations, flight attendants should meet minimum health standards and not be impaired by factors such as fatigue. In addition, the unique occupational and environmental characteristics of flight attendant employment may have consequential occupational health and safety implications, including radiation exposure, cancer, mental ill-health, musculoskeletal injury, reproductive disorders, and symptoms from cabin air contamination. The respective roles of governments and employers in managing these are controversial. A structured literature review was undertaken to identify key themes for promoting a future agenda for flight attendant health and safety. Recommendations include breast cancer health promotion, implementation of Fatigue Risk Management Systems, standardization of data collection on radiation exposure and health outcomes, and more coordinated approaches to occupational health and safety risk management. Research is ongoing into cabin air contamination incidents, cancer, and fatigue as health and safety concerns. Concerns are raised that statutory medical certification for flight attendants will not benefit either flight safety or occupational health. PMID:22606869

Space Station Freedom as an engineering experiment station: An overview  

Science.gov (United States)

In this presentation, the premise that Space Station Freedom has great utility as an engineering experiment station will be explored. There are several modes in which it can be used for this purpose. The most obvious are space qualification, process development, in space satellite repair, and materials engineering. The range of engineering experiments which can be done at Space Station Freedom run the gamut from small process oriented experiments to full exploratory development models. A sampling of typical engineering experiments are discussed in this session. First and foremost, Space Station Freedom is an elaborate experiment itself, which, if properly instrumented, will provide engineering guidelines for even larger structures which must surely be built if humankind is truly 'outward bound.' Secondly, there is the test, evaluation and space qualification of advanced electric thruster concepts, advanced power technology and protective coatings which must of necessity be tested in the vacuum of space. The current approach to testing these technologies is to do exhaustive laboratory simulation followed by shuttle or unmanned flights. Third, the advanced development models of life support systems intended for future space stations, manned mars missions, and lunar colonies can be tested for operation in a low gravity environment. Fourth, it will be necessary to develop new protective coatings, establish construction techniques, evaluate new materials to be used in the upgrading and repair of Space Station Freedom. Finally, the industrial sector, if it is ever to build facilities for the production of commercial products, must have all the engineering aspects of the process evaluated in space prior to a commitment to such a facility.

Introduction to Space Station Freedom  

Science.gov (United States)

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 Freedom in FY 92 was appropriated. For FY 93, NASA is seeking $2.25 billion for the program; the planned budget for FY 94 is $2.5 billion. Further alterations to the hardware configuration for Freedom would be a serious setback; NASA intends 'to stick with the current baseline' and continue planning for utilization.

Business opportunities with station cars  

Energy Technology Data Exchange (ETDEWEB)

The topics of discussion include: station car properties, station car vs. full function BEVs, applications/opportunities, infrastructure paradigm shift, regulatory paradigm shift, and a Ford EV model. The attributes of station cars include: personal mobility rentals, designed for short trips and urban settings, fast check-in/check-out, short return cycles, an improvement for urban congestion and parking, and it must meet all automotive regulatory and safety requirements. In a comparison between station cars and full function BEVs, the first is significantly less costly but has the same range, it can be used in restricted areas, its size, weight, range, and maintenance are all more practical, and it is friendly to a block-heater infrastructure. Reasons why customers should care are offered. Applications of station cars are cited including: city use/commercial, in closed, environmentally minded communities, resorts/national parks, and personal use. There is an infrastructure opportunity in a shift that has occurred from range extension to zone support. A regulatory opportunity has been created because of a paradigm shift from zone restrictions, WEV mandates, and HOV driving lane privileges to clean transport program incentives, merchant/city zone incentives, and mass transit incentives. A Ford EV model's appeal is described. Opportunities are summarized for the use of these vehicles.

Shippingport station decommissioning project overview  

International Nuclear Information System (INIS)

The US Department of Energy (DOE) is in the process of decommissioning the Shippingport Atomic Power Station (SAPS), the first commercial-sized nuclear power plant in the United States to undergo complete dismantlement. SAPS is located near Pittsburgh, Pennsylvania, on approximately seven acres of land owned by Duquesne Light Company (DLC), and leased to the US Department of Energy. The Station consists of a 275' by 60' Fuel Handling Building containing the Reactor Containment Chamber, the Service Building, the Turbine Building, the Radioactive Waste Processing Building, the Administration Building, and other smaller support buildings. The Station has four coolant loops; most of the containment structures are located below grade. Shippingport Station was shutdown in October, 1982. Defueling operations began in 1983 and were completed by September 1984. At that time, responsibility for the plant was transferred from DOE Office of Assistant Secretary for Naval Reactors (NE-60) to DOE Office of Terminal Waste Disposal and Remedial Action (NE-20) and then to DOE Richland Operations Office (RL). Also at that time, responsibility for the operation/decommissioning of the station systems passed from DLC to General Electric Company (GE). A caretaker and site preparation period lasted from September, 1984 to September, 1985, at which time decommissioning activities started. The decommissioning period is scheduled as September, 1985 through April, 1990. Project total estimated cost is $98.3 million

Douglas Point Generating Station Commissioning  

International Nuclear Information System (INIS)

This paper discusses a number of the interesting experiences encountered at the Douglas Point Nuclear Power Station. Sufficient background with respect to the basic process, equipment location, and commissioning history is given so that those not familiar with the station may follow the remainder of the paper. Three commissioning philosophies followed in the commissioning of Canadian nuclear power stations are mentioned: (1) no ordinary water used for commissioning heavy-water systems: (2) fuelling machines used for initial fuel loading; (3) no portable steam-generating equipment for preliminary turbine-generator run up. Against this background the following experiences are mentioned: low power physics measurements; fuel channel replacement and faulty booster removal; heat transport pressure control; ion-exchange resin in the heat transport system; heat transport pumps; boiler level control; possible fretting of pressure tubes; turbine operation; heavy-water experience. The paper concludes by mentioning some important lessons learned from the experience to date and states confidence in the future of Douglas Point Generating Station, and future Canadian nuclear power stations.

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

Energy Technology Data Exchange (ETDEWEB)

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.

Breast cancer screening adherence: does church attendance matter?  

Science.gov (United States)

Little is known about the health behaviors of church attendees. This article reviewed telephone interview data of 1,517 women who were church members from 45 churches located in Los Angeles County to determine their breast cancer screening status and to identify the key predictors of screening. Almost all of this sample (96%) reported attending church at least once a month. Key predictors of screening included physician-patient communication, ethnic background, and having medical insurance. Although church-related predictors were not significantly related to screening adherence, the authors compared community-based screening rates from another sample to their sample rates and found that, when controlling for income and education, church members fared better on mammography screening than women who were community residents. This finding suggests that frequent church attendance contributes to better mammography screening status and that the relationship between religious involvement and health behaviors needs further explanation.

Parental awareness and dental attendance of children among African immigrants.  

Science.gov (United States)

To assess parental awareness of their child's dental status and the relationship between parental awareness and children's dental attendance. Participants were children aged 6 years or younger and their African parents who had lived in Canada for up to 10 years. Demographics and parents' perceived dental status were collected. Children's normative dental status was determined by dental examinations. 125 pairs of parents and children aged 21-72 months were included. 52% of the children never had a dental visit. Dental status of 44% of children was rated as good by parents, among them, 56% had dental decay. Parental assessments did not coincide with the clinical assessments of 62% of children. No correlation was found between parental awareness and children's dental attendance.

An Investigation of Creativity Among Children Attending Preschools  

Directory of Open Access Journals (Sweden)

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.

Pup growth and maternal attendance patterns in Subantarctic fur seals  

Directory of Open Access Journals (Sweden)

Full Text Available Samples of pups from the expanding populations of Subantarctic fur seals (Arctocephalus tropicalis at Marion and Gough islands were weighed at specific ages between birth and weaning in the period 1993-2000. Growth was estimated and compared between years, sexes, sites of different density, and populations. Pups of comparable age were consistently heavier at Marion Island than at Gough Island, probably reflecting relative prey resource abundance. No changes in pup growth rates were apparent over the study period, nor was there any evidence that growth was affected by ENSO events. Measures of pup growth at Marion Island were complemented by measures of maternal attendance behaviour during three summer and winter seasons. More years of data are required to determine patterns between attendance, growth, resource conditions and population abundance trends.

Space Stations: Sponge Spool Spine  

Science.gov (United States)

In this activity, learners simulate what happens to a human spine in space by making Sponge Spool Spines (alternating sponge pieces and spools threaded on a pipe cleaner). This represents a human spine on Earth, with the discs (sponges) pressed between the spinal vertebrae (the wooden spools). Learners measure the spine length, dip it in a glass of water (simulating microgravity), and then re-measure the spine. They will find it has expanded, just like in space! This activity station is part of a sequence of stations that can be set up to help learners explore how space affects the human body and why.

Analyses of power station economy  

International Nuclear Information System (INIS)

A comparison of construction, fuel and other running costs of electricity production based on conventional coal/oil-fired plants and on atomic power stations. These types of stations are selected: a 600 MW coal/oil-fired plant, a 900 MW atomic power plant of LWR type, and a 635 MW atomic power plant of CANDU type. The comparison serves to elucidate the immediate effects on social economics that the choice between conventional and atomic power production must be presumed to have for investments, fuel consumption, running costs and consumer prices for electricity, as well as for currency costs and employment during the construction and operation of power plants.

Does distance determine who attends a university in Germany?  

OpenAIRE

We analyze the role of distance from a university in the decision to attend higher education in Germany. Students who live near a university can avoid moving and the increased living expenses by commuting. Thus, transaction cost arguments would suggest that the greater the distance to the nearest university, the lower the participation in higher education. We analyze this hypothesis by combining data from the German Socio-Economic Panel Study (SOEP) with a database from the German Rectors' Co...

Space Station power system issues  

International Nuclear Information System (INIS)

Issues governing the selection of power systems for long-term manned Space Stations intended solely for earth orbital missions are covered briefly, drawing on trade study results from both in-house and contracted studies that have been conducted over nearly two decades. An involvement, from the Program Development Office at MSFC, with current Space Station concepts began in late 1982 with the NASA-wide Systems Definition Working Group and continued throughout 1984 in support of various planning activities. The premise for this discussion is that, within the confines of the current Space Station concept, there is good reason to consider photovoltaic power systems to be a venerable technology option for both the initial 75 kW and 300 kW (or much greater) growth stations. The issue of large physical size required by photovoltaic power systems is presented considering mass, atmospheric drag, launch packaging and power transmission voltage as being possible practicality limitations. The validity of searching for a cross-over point necessitating the introduction of solar thermal or nuclear power system options as enabling technologies is considered with reference to programs ranging from the 4.8 kW Skylab to the 9.5 gW Space Power Satellite

Computer networking at SLR stations  

Science.gov (United States)

There are several existing communication methods to deliver data from the satellite laser ranging (SLR) station to the SLR data center and back: telephonmodem, telex, and computer networks. The SLR scientific community has been exploiting mainly INTERNET, BITNET/EARN, and SPAN. The total of 56 countries are connected to INTERNET and the number of nodes is exponentially growing. The computer networks mentioned above and others are connected through E-mail protocol. The scientific progress of SLR requires the increase of communication speed and the amount of the transmitted data. The TOPEX/POSEIDON test campaign required to deliver Quick Look data (1.7 kB/pass) from a SLR site to SLR data center within 8 hours and full rate data (up to 500 kB/pass) within 24 hours. We developed networking for the remote SLR station in Helwan, Egypt. The reliable scheme for data delivery consists of: compression of MERIT2 format (up to 89 percent), encoding to ASCII Me (files); and e-mail sending from SLR station--e-mail receiving, decoding, and decompression at the center. We do propose to use the ZIP method for compression/decompression and the UUCODE method for ASCII encoding/decoding. This method will be useful for stations connected via telephonemodems or commercial networks. The electronics delivery could solve the problem of the too late receiving of the FR data by SLR data center.
