Following several years of work, the construction of the Jardin Alpin – CERN tramline is almost complete, and the first tram is due to arrive at CERN on 30 April. Celebrations to mark the occasion will be held in Meyrin-Village and at CERN.   First tests of the overhead lines, signals, and tracks on the stretch between Jardin-Alpin and CERN on 7 April 2011. From 30 April onwards you will be able to travel from Cornavin station to CERN non-stop in 20 minutes using the No. 18 tram. This is great news, especially when you think that, only four years ago, no part of the stretch between Cornavin and CERN was served by a tramline. At present, if you want to travel between CERN and the city centre by public transport, you have to take the No. 14 or the No. 16 tram and the No. 56 bus, changing at Meyrin-Gravière, where you sometimes have quite a long wait. On 30 April all this will be a thing of the past! The construction work for the Geneva-CERN tramline began in January 20...

The complicated transition to competition in the petrol industry in Spain

International Nuclear Information System (INIS)

Perdiguero, J.; Borrel, J. R.

2007-01-01

The Spanish petrol market has been deeply restructured. However, the results of two decades of liberalization are mixed. A more active policy of fostering and defending competition has been missing. Reform efforts in the sector and economic analyses of the markets have overwhelming been focussed on the upstream activities of manufacturing and wholesaling. By contrast, other activities of the sector are the ones that are constraining competition. Vertical relations between petrol major companies and petrol stations have a very significant impact on the process to achieve effective competition. And access to distribution essential facilities such as pipes is a necessary condition to open up the market to new operators. In Spain, transition to competition in the petrol industry has not taken enough care on restructuring vertical relations and access to essential facilities. (Author)

Greening the streets of CERN

CERN Multimedia

2011-01-01

This week, CERN took delivery of bi-fuel cars for the first time. Designed to run on petrol or natural gas, these vehicles represent a cost effective way to reduce our emissions immediately. With widely distributed sites and considerable personal transport needs, this is an important step forward and another clear indication of CERN’s green credentials.   CERN’s internal public transport service, if I can put it that way, consists of some 500 bicycles, an on-site shuttle service that has transported over 40000 people in the last 12 months, and a sizeable fleet of light vehicles numbering 866 in total. As vehicle contracts come to an end, we are constantly on the lookout for greener solutions to our transport needs. Today, natural gas is the ideal solution, being less polluting than either petrol or diesel. Although the vehicles cost slightly more than their petrol equivalents, the difference is partially subsidised by the Swiss natural gas industry, and we consider the emissio...

Early Liver and Kidney Dysfunction Associated with Occupational Exposure to Sub-Threshold Limit Value Levels of Benzene, Toluene, and Xylenes in Unleaded Petrol.

Neghab, Masoud; Hosseinzadeh, Kiamars; Hassanzadeh, Jafar

2015-12-01

Unleaded petrol contains significant amounts of monocyclic aromatic hydrocarbons such as benzene, toluene, and xylenes (BTX). Toxic responses following occupational exposure to unleaded petrol have been evaluated only in limited studies. The main purpose of this study was to ascertain whether (or not) exposure to unleaded petrol, under normal working conditions, is associated with any hepatotoxic or nephrotoxic response. This was a cross-sectional study in which 200 employees of Shiraz petrol stations with current exposure to unleaded petrol, as well as 200 unexposed employees, were investigated. Atmospheric concentrations of BTX were measured using standard methods. Additionally, urine and fasting blood samples were taken from individuals for urinalysis and routine biochemical tests of kidney and liver function. The geometric means of airborne concentrations of BTX were found to be 0.8 mg m(-3), 1.4 mg m(-3), and 2.8 mg m(-3), respectively. Additionally, means of direct bilirubin, alanine aminotransferase, aspartate aminotransferase, blood urea and plasma creatinine were significantly higher in exposed individuals than in unexposed employees. Conversely, serum albumin, total protein, and serum concentrations of calcium and sodium were significantly lower in petrol station workers than in their unexposed counterparts. The average exposure of petrol station workers to BTX did not exceed the current threshold limit values (TLVs) for these chemicals. However, evidence of subtle, subclinical and prepathologic early liver and kidney dysfunction was evident in exposed individuals.

Benzene emission from the actual car fleet in relation to petrol composition in Denmark

Palmgren, F.; Hansen, A.B.; Berkowicz, R.; Skov, H.

2001-01-01

The present study covers an investigation of the trends in air pollution levels of benzene in Danish cities and their relationship with the benzene content in petrol. Petrol samples from the two refineries in Denmark as well as sold petrol from some representative Danish petrol stations were analysed. The benzene content in Danish petrol was reduced from 3.5% for 95 octane prior to 1995 to approx. 2% in 1995 and further to 1% in 1998. Air quality measurements of aromatic VOC are available from two Danish cities; Copenhagen since 1994 and Odense since 1997. Measurements of benzene, CO and NO x from these two locations were analysed using the Operational Street Pollution Model (OSPM) and trends in the actual emissions of these pollutants were determined. It is shown that the decrease in both the concentration levels and in the emissions was significantly larger for benzene than for CO and NO x . The decreasing trends of NO x and CO could be explained by the increasing fraction of petrol-fuelled vehicles with three way catalysts (TWC). The much steeper decreasing trend for benzene can most likely be attributed to a combination of the effect of the increasing share of the TWC vehicles and a simultaneous reduction of benzene content in Danish petrol. The reduction of benzene concentrations and emissions is observed despite that the total amount of aromatics in petrol has increased slightly in the same period. (Author)

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. (author)

We measured levels of VOCs and determined the distributions of benzene concentrations over the area of two petrol stations in all three seasons. Using the concentrations and sampling positions, we created isoconcentration contour maps. The average concentrations ranged 18-1288 μg m(-3) for benzene and 12-81 μg m(-3) for toluene. The contour maps indicate that high-level contours of benzene were found not only at the fuel dispenser areas but also at the storage tank refilling points, open drainage areas where gasoline-polluted wastewater was flowing, and the auto service center located within the station area. An assessment of the benzene to toluene ratio contour plots implicates that airborne benzene and toluene near the fuel dispenser area were attributed to gasoline evaporation although one of the studied stations may be influenced by other VOC sources besides gasoline evaporation. Additionally, during the routine refilling of the underground fuel storage tanks by a tank truck, the ambient levels of benzene and toluene increased tremendously. The implementation of source control by replacing old dispensers with new fuel dispensers that have an efficient cutoff feature and increased delivery speed can reduce spatial benzene concentrations by 77%. Furthermore, a questionnaire survey among 63 service attendants in ten stations revealed that headache was the most reported health complaint with a response rate of 32%, followed by fatigue with 20%. These prominent symptoms could be related to an exposure to high benzene concentrations.

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

Rosa María Rosales Aranda

2012-01-01

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

2011-10-01

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%.

Overview of different control strategies for a typical cryogenic warm compressor station at CERN

Pezzetti, M.; Garcia, C. V. M.; Bradu, B.; Rogez, E.

2017-12-01

Helium cryogenic systems are extensively used at CERN under several configurations for accelerators and detectors. The Warm Compressor Station (WCS) is the primary component of the helium cryogenic systems. The basic controls structure mainly depends on the bypass, charge and discharge valves configuration ensuring the nominal flow and compression ratio. This paper presents three studied methods for the WCS process control systems covering all transient and operational requirements: the proportional-integral-derivative (PID) control approach, the Fuzzy Logic Control approach (FLC) and the Internal Model Control approach (IMC). The paper emphasizes on simulation results of the different control strategies using Ecosimpro software associated to the CERN CryoLib library. Advantages and limitations of each method are presented.

Idiosyncrasies in Australian petrol price behaviour: evidence of seasonalities

International Nuclear Information System (INIS)

Mitchell, Jason D.; Lilian Ong; Izan, H.Y.

2000-01-01

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)

Tobacco use, Body Mass Index, and Potentially Malignant Disorders Among petrol fillers in Pimpri-Pune (India: A descriptive study

Mamatha G. S. Reddy

2014-01-01

Full Text Available Background: Since petrol is combustible and smoking is banned at the petrol pumps, it may be predicted that use of smokeless tobacco is more prevalent among the petrol fillers. Also, smokeless tobacco is a major risk factor for developing oral potentially malignant disorders. The present study was conducted to determine the tobacco use, body mass index (BMI, and potentially malignant disorders among a cohort of petrol fillers and also to evaluate the interaction of tobacco use and BMI with the presence of potentially malignant disorders. Settings and Design: The study was conducted at 45 petrol stations located at Pimpri-Pune, India. A descriptive study design was used. Materials and Method: Four hundred and ten petrol fillers aged 17-64 years participated in the study. General information and tobacco history was obtained by interview. Height and weight were recorded to obtain BMI. Oral examination was conducted to identify the potentially malignant disorders. Statistical analysis: Chi-square test, Z test, and logistic regression were used. The level of significance was fixed at 5%. Results and Conclusions: It was found that 242 (59.02% used tobacco in different forms. 77.68% were tobacco chewers, and 8.26% were smokers. Leukoplakia was prevalent among 68.47%, oral submucous fibrosis among 27.45%, and 5.08% had erythroplakia. Age (χ2 = 11.46, P < 0.05, duration (χ2 = 17.46, P < 0.05, and frequency of tobacco chewing (χ2 = 14.16, P < 0.05 were significantly associated with potentially malignant disorders. Tobacco chewing was more prevalent as compared to smoking. It can be concluded that the petrol fillers are at a high risk for developing oral potentially malignant disorders.

Petrol with isotopically differentiated lead added

International Nuclear Information System (INIS)

Magi, F.; Facchetti, S.; Garibaldi, P.

1975-01-01

An experiment is proposed aimed at determining the role of motor traffic in the pollution of the environment by lead, in particular of air, soil, vegetation, food and the human body. The technique of determining the isotopic composition of lead, used in the right way, should enable the whole problem to be solved. It is intended to add lead with a constant isotopic composition different from that of normally occuring lead, whether natural in origin or otherwise, to petrol in at least two regions of Italy. Analyses of lead samples taken from the principal mines have shown that Australian lead (Broken Hill Mine) has quite a different isotopic composition. This lead will therefore be used to prepare the antiknock additives for petrol sold in the regions in question. Adequate sampling should make it possible to determine the contribution to pollution of lead from motor vehicle exhausts. The regions chosen for the experiment are Piedmont (city and province of Turin) and Sardinia (city and province of Cagliari) - the first because of its high traffic density and level of industrialization, the second because of its remoteness and the lead content of the soil, which may affect food. Both regions present favourable conditions for supplying petrol of the intended type. The experiment is intended to last three years; the petrol with Australian lead will be marketed for a period of 18 months. The first results of analyses of the isotopic composition of lead contained in atmospheric dust in the city of Turin and of lead from a number of blood samples are reported in the paper

A new concept for the water supply at CERN

CERN Document Server

Inigo-Golfin, J

1998-01-01

The present state of the station Le Vengeron (the main pumping station supplying CERN with drinking water), and also to comply with the new Swiss standards impose a thorough consolidation and upgrade of this station which is shared with the Services Industriels de Genève (SIG). The total cost of the works (around 62 MCHF) would be shared proportionally to the nominal flow-rate demand which, at present, is of 2/3 for CERN and 1/3 for SIG. An alternative to the above is a complete review of CERN's water consumption, reducing our needs by half, thus allowing savings in both investment and operation. This reduction in investment cost would be diverted towards much needed consolidation works for the existing facilities within CERN. This paper also reviews the planning and possible ways for the execution of the works and the future responsibilities of operation of the water distribution systems (drinking and machine) inside CERN's sites.

Relation between lead in air and in petrol in two urban areas of Britain

Science.gov (United States)

Pattenden, N. J.; Branson, J. R.

The recent reduction in the lead content of petrol in the United Kingdom, following government legislation, has been used to investigate the relationship between lead in petrol and in outside air in urban environments. In parts of London and Manchester, the airborne lead concentration closely followed the petrol lead concentration, within a time resolution of about 1 month. These results indicate that, in these areas, the petrol lead content has a fairly direct and prompt effect on the urban air lead concentration, i.e. any environmental lead reservoirs in the pathway from petrol to air (and hence to man by inhalation) are not significant on this timescale. A small component of the airborne lead, apparently independent of the petrol lead, was also observed.

2010-06-01

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

Modelling how much extra motorists pay on the road? A cross-sectional study of profit margins of unleaded petrol in Australia

International Nuclear Information System (INIS)

Valadkhani, Abbas; Babacan, Alperhan

2014-01-01

Gross profitability margin (difference between retail and wholesale prices) for unleaded petrol exhibits substantial variations across 108 cities, towns and regional centres in Australia. This paper examines if such variations (averaged during 2007–2012) can be explained by (a) transport costs proxied by the distance between retailers and wholesalers; (b) the size of the retail market; (c) market competition proxied by the number of cars in the vicinity of the retailers; (d) dummy variables capturing other qualitative attributes associated with the retailers’ locations. Three cross-sectional regressions are estimated but only one successfully passes all diagnostic tests. By identifying a number of locations exhibiting excessive profit margins, the results of this paper enhance the efficiency and transparency of petrol pricing in the retail market. It is found that the extent of excessive profiteering in Western Australia (WA) and South Australia (SA) were lower than other Australian states and territories. This important finding can be explained by a strong presence of independent petrol stations in SA and the successful price-monitoring performance of FuelWatch in WA. - Highlights: • We examine the profit margin for petrol across 108 retail locations in Australia. • No evidence of excessive profiteering was found in 76 out of 108 retail locations. • There are 13 locations in which the likelihood of abnormal margins is quite high. • Regulatory bodies have limited resources so they should target these locations

Pb is a trace metal that tracks anthropogenic pollution in natural environments. Despite recent leaded petrol phase out around Southeast Asia, the region's growth has resulted in continued exposure of Pb from a variety of sources. In this study, sources of Pb into Singapore, a highly urbanised city-state situated in the central axis of Southeast Asia, are investigated using isotopic ratios and concentrations. We compiled data from our previous analyses of aerosols, incineration fly ash and sediments, with new data from analyses of soil from gas stations, water from runoff and round-island coastal seawater to obtain a spatio-temporal overview of sources of Pb into the Singapore environment. Using 206 Pb/ 207 Pb ratio, we identified three main Pb source origins: natural Pb (1.215 ± 0.001), historic/remnant leaded petrol (1.123 ± 0.013), and present-day industrial and incinerated waste (1.148 ± 0.005). Deep reservoir sediments bore larger traces of Pb from leaded petrol, but present-day runoff waters and coastal seawater were a mix of industrial and natural sources with somewhat variable concentrations. We found temporal variability in Pb isotopic ratio in aerosols indicating alternating transboundary Pb sources to Singapore that correspond to seasonal changes in monsoon winds. By contrast, seasonal monsoon circulation did not significantly influence isotopic ratios of coastal seawater Pb. Instead, seawater Pb was driven more by location differences, suggesting stronger local-scale drivers of Pb such as point sources, water flushing, and isotope exchange. The combination of multiple historic and current sources of Pb shown in this study highlights the need for continued monitoring of Pb in Southeast Asia, especially in light of emerging industries and potential large sources of Pb such as coal combustion.

Petrol pump workers are occupationally exposed to gasoline and its fumes consisting of several mutagenic chemicals. To evaluate the genotoxic effects of exposure to gasoline fumes on petrol pump workers. The study groups included 70 petrol pump workers (exposed group) and 70 healthy age-matched individuals with no known exposure (comparison group). Buccal micronucleus cytome assay (BMCyt) was performed to check the genotoxicity caused due to inhalation of gasoline fumes. The frequencies of micronucleated cells, nuclear bud, condensed chromatin cells, karyorrhectic cells, pyknotic cells, and karyolytic cells were significantly higher in the exposed workers compared to the comparison group. Exposure to gasoline fumes is associated with increased frequency of cell abnormalities. This may lead to various health consequences including cancer in those occupationally exposed to gasoline fumes.

1993-01-01

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

Quantification of atmospheric lead emissions from 70 years of leaded petrol consumption in Australia

Science.gov (United States)

Kristensen, Louise Jane

2015-06-01

Lead is a persistent pollutant and the subject of many environmental studies, yet, in Australia, the extent of atmospheric lead emissions from the use of leaded petrol is unquantified. This paper details the first comprehensive account of leaded petrol sales and its lead concentrations over the 70 years of use in Australia. The resulting atmospheric lead emissions are calculated to provide the most complete understanding of the volume of lead released to the Australian continent from the consumption of leaded petrol. Atmospheric emissions of lead to the entire Australian continent from leaded petrol are calculated to total 240,510 tonnes over seven decades of use, peaking at 7869 tonnes in 1974. Total emissions for individual states and territories range from 1745 to 67,893 tonnes, with New South Wales responsible for the largest emissions. The effect of regulations on allowable concentrations of tetraethyl-lead additives are observed in the reduction of lead emissions in New South Wales and Victoria. The consequences to human health and the environment of leaded petrol consumption in Australia's populous cities are examined against historical air quality data and blood lead levels.

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

Directory of Open Access Journals (Sweden)

Eliezer Uchechukwu Okeke

2013-04-01

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.

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

Directory of Open Access Journals (Sweden)

Mark A. S. Laidlaw

2015-12-01

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

The impact of subsidized low aromatic fuel (LAF) on petrol (gasoline) sniffing in remote Australian indigenous communities.

Science.gov (United States)

d'Abbs, Peter; Shaw, Gillian; Field, Emma

2017-08-17

Since 2005, the Australian Government has subsidized the production and distribution of Low Aromatic Fuel (LAF) as a deterrent against petrol (gasoline) sniffing in remote Indigenous communities. LAF is used in place of unleaded petrol as a fuel for vehicles and other engines. This paper reports findings from an independent evaluation of the LAF rollout. Forty one Indigenous communities were surveyed between 2010 and 2014, with each community being visited twice at a two yearly interval. Quantitative data on prevalence of petrol sniffing were collected, as well as qualitative data on the acceptability of LAF, evidence of substitution for inhaled petrol with other drugs, and programs such as recreational, training and employment opportunities. Prevalence rates of sniffing per 1000 population for each survey year and community were calculated by dividing the total number of sniffers by the population aged 5-39 years and multiplying by 1000. Between 2011-12 and 2013-14, the total estimated number of people sniffing petrol declined from 289 to 204, a fall of 29.4%. At both times, the median petrol sniffing prevalence rate was lower in communities with LAF than in communities without LAF. In 17 of the 41 communities, comparable data were available over a longer period, commencing in 2005-06. Fifteen of these communities stocked LAF over the entire period. In these communities, the median rate of petrol sniffing declined by 96%, from 141.6 per 1000 population in 2005-06 to 5.5 in 2013-14 (p < 0.05). LAF was widely accepted, although acceptance was often qualified by a belief that LAF harmed engines. Anecdotal reports suggest that the fall in petrol sniffing may have been offset by increased use of cannabis and other drugs, but the relationship is not one of simple cause-and-effect, with evidence that an increase in cannabis use in communities commenced before the LAF rollout began. Provision of services in communities has improved in recent years, but many programs

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.

Laser fluorescent method for monitoring leaks from petrol pipes based on the neural network algorithm

Directory of Open Access Journals (Sweden)

M. L. Belov

2014-01-01

Full Text Available Current systems for monitoring leaks from petrol pipes can detect large leaks only, and their sensitivity limit is about 1% of the whole petrol pipe’s capacity. In this paper, a problem of remote detection of small leaks (less than 1% from petrol pipes was considered. One of possible variations of such a system is a monitoring system of oil pollution at the earth surface along the petrol pipe. In this paper experimentally obtained data such as fluorescence spectra of oil products (crude oil, light-end oil products, heavy oil products, various earth surfaces (soil, vegetation, water, asphalt and oil products spilled over various earth's surface were used for the excitation wavelength of 266 nm. It was shown that use of the laser method based on detection of fluorescence radiation within three narrow spectral bands and a neural network algorithm of measured data processing allowed one to detect oil pollution on the earth surface with a probability of correct classification close to 1 and low probability of false alarm.

Change of public transport services for CERN

CERN Multimedia

From 9 December onwards, the Number 9 bus, which used to run from Petit-Bel-Air all the way through to CERN, will terminate at Cornavin. With the first stretch of the new Cornavin-Meyrin-CERN tram route now in service, trams 14 and 16 will run from Cornavin to Avanchet (next to the Balexert shopping centre). During construction of the section through to Meyrin and CERN, two new bus services will be available from Avanchet, the 55 to Meyrin Village and the 56 to CERN. The Y bus route has been modified between Blandonnet and the Hôpital de la Tour: buses will no longer transit via Meyrin-Village but via the Meyrin-Satigny business park. The Y bus route has also been extended from Blandonnet to Avanchet so as to establish a connection with the tram routes 14 and 16. To get to CERN from Cornavin station during this period, you should therefore take a number 14 or 16 tram and then a number 56 bus. For further information: www.tpg.ch

Experimental analysis on a spark ignition petrol engine fuelled with LPG (liquefied petroleum gas)

International Nuclear Information System (INIS)

Masi, Massimo

2012-01-01

The use of LPG (liquefied petroleum gas) as alternative fuel to petrol is common practise in spark ignition engines. While the main driving force to the use of LPG still remains the low cost for the end user, its favourable pollutant emissions, in particular carbon dioxide, will in the middle term probably increase interest in LPG as an IC engine fuel. In addition, there are both theoretical and technical reasons to consider LPG as an attractive fuel also in terms of engine performance. Despite the continuously increasing stock production of dual-fuel (petrol–LPG) passenger car models, doubts still exist about both real engine performance in LPG operation and the reliability of the dual-fuel feeding system. This paper deals with the theoretical advantages of using LPG as fuel for SI engines. Brake performance tests of a passenger car engine fed with petrol and LPG are analysed and compared. The stock engine has been equipped with a “third-generation” standard kit for dual-fuel operation. The performance reductions in LPG operation are discussed in both steady state and transient condition. The results of some modifications to the set-up of both the petrol and LPG metering devices, designed for a better justification of the measured performance, are also presented. -- Highlights: ► Experimental research on the actual performances of an SI engine fed with petrol and gaseous LPG. ► Theoretical advantages and drawbacks of fuelling SI ICE’s with LPG. ► Brake performance analysis shows a noticeable gap between LPG and petrol operation. ► Local measurements confirm that the thermodynamic operation of the evaporator-pressure reducer device is crucial for the engine performance. ► The performance of the up-to-date kit for petrol–LPG dual-fuel operation is greatly affected by the settings of the mechanical components of the LPG evaporator device.

Wu, Di; Zhang, Fei; Lou, Wenhao; Li, Dan; Chen, Jianmin

2017-12-15

Fuel consumption is one of the major contributors to air pollution worldwide. Plenty of studies have demonstrated that the diesel and petrol exhaust fine particulate matters (FPMs) are associated with increases of various diseases. However, the influences of different fuel types and their chemical components on toxicity have been less investigated. In this study, four kinds of fuels that widely used in China were burned in a laboratory simulation, and the FPMs were collected and analyzed. Transmission electron microscopy showed that black carbon was mainly soot with a dendritic morphology. For light diesel oil, marine heavy diesel oil, 93 octane petrol and 97 octane petrol diesel oil, the emission factors of FPMs were 3.05±0.29, 3.21±0.54, 2.36±0.33, and 2.28±0.25g/kg fuel, respectively. And the emission factors for the "16 US EPA" PAHs of FPM were 0.45±0.20, 0.80±0.22, 1.00±0.20, and 1.05±0.19mg/g FPMs, respectively. Fe is the most abundant metal in these FPMs, and the emission factors of FPMs were 2.58±1.70, 4.45±0.11, 8.18±0.58, and 9.24±0.17mg/g FPMs, respectively. We ranked the cytotoxicity of the FPMs emission from fuels combustion: marine heavy diesel oil>97 octane petrol>93 octane petrol>light diesel oil, and the genotoxicity of FPMs emission from fuels combustion: marine heavy diesel oil>light diesel oil>93 octane petrol>97 octane petrol. Significant correlations were found between PAH concentrations and reactive oxygen species (ROS) generation. Our results demonstrated that fuels exhaust FPMs have strong association with ROS activity, cytotoxicity and genotoxicity. These results indicated that fuels exhaust FPMs pose a potentially serious health, and emphasized the importance of assessing the health risks posed by the particulate pollutants in vehicle exhausts.

2015-12-01

Petrol cars, in particular nonhybrid cars, contribute significantly to the pollution problem as compared with other types of cars. The originality of this article falls in the direction of using hydro-oxy gas to reduce pollution from petrol car engines. Experiments were performed in city areas at low real speeds, with constant engine speeds in the average of 2500 rpm and at variable velocity ratios (first speed was 10-20 km/hr, second speed was 20-35 km/hr, and third speed was 35-50 km/hr). Results indicated that through using hydro-oxy gas, a noticeable reduction in pollution was recorded. Oxygen (O2) percentage has increased by about 2.5%, and nitric oxide (NO) level has been reduced by about 500 ppm. Carbon monoxide (CO) has decreased by about 2.2%, and also CO2 has decreased by 2.1%. It's worth mentioning that for hybrid system in cars at speeds between 10 and 50 km/hr, the emission percentage change is zero. However, hybrid cars are less abundant than petrol cars. The originality of this paper falls in the direction of using hydro-oxy gas to reduce pollution from petrol car engines. Experiments were performed in city areas at low real speeds, with constant engine speeds in the average of 2500 rpm and at variable velocity ratios (first speed was 10-20 km/hr, second speed was 20-35 km/hr, and third speed was 35-50 km/h).

CERN is where the web was born, and remains a hothouse of innovation in information technology (IT). In this fourth First Tuesday @ CERN, we look at industrial partnership at CERN in the IT area from several different angles. The approach taken by CERN with software licencing - a very hot topic in the world of IT - will be discussed. The benefits that CERN hardware and software suppliers gain from working with CERN will be presented, and the CERN openlab, a new approach to industrial partnership at CERN, will be covered. A novel ingredient of this First Tuesday @ CERN is that it will be run in parallel with a similar event for the business community in London, and there will be webcast presentations between the Queen Elizabeth II Conference Centre in London and CERN during the event. Thus, First Tuesday @ CERN will take on a truly European dimension, to reflect CERN's European character.

2006-01-01

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

Sarin, S M; Singh, A; Sharma, N; Sharma, K; Shanmugum, P

2001-01-01

The tail pipe CO (carbon monoxide) and HC (hydrocarbon) emission characteristics of in-use petrol driven vehicles were evaluated between November 1996 through September 1997 in Delhi. A total of 4300 vehicles were checked at CRRI Pollution Checking Centre. Approximately 90% of the total vehicles meet the prescribed CO emission standards even without following routine I/M practices. The age of the vehicles appeared to have influence on the emission characteristics. The non-compliance level was found to be higher for older vehicles. Insignificant correlation was observed between CO and HC emissions for all categories of in-use petrol driven vehicles. The emission reduction (gain) in CO and HC emissions was observed for two wheelers equipped with four-stroke engines and four wheelers fitted with catalytic converters over their respective conventional vehicles. The observed high compliance levels indicate that existing tail pipe emission standards are lenient and need to be reviewed. The emission standards are proposed for different categories of in-use petrol driven vehicles.

Major Refit for CERN's 400 kV Substation

CERN Multimedia

2001-01-01

The 400 kV substation on the Prévessin site brings in the electricity that powers CERN's accelerators and the majority of the Laboratory's installations. It was originally built in the 1970s for the SPS, and is one of only five privately owned 400 kV sub-stations in France. Three of the others belong to the national railway company, SNCF, supplying the Paris-Marseilles TGV line, the other is at the Cadarache research centre near mouth of the Rhone. After nearly thirty years of service, CERN's substation has just undergone a complete overhaul. The new main 18 kV switchboard for the SPS pulsed network. The electricity supply for the original Prévessin substation was from the 400 kV EDF network, delivered through three 90 MW transformers at 18 kV to the SPS pulsed network, With the arrival of LEP, two 110 MW transformers were added to supply the new accelerator. Now, as CERN gears up for the LHC, additional pulsed power capacity is needed to supply the transfer lines carrying protons from...

Full Text Available ÖZ: Bu çalışmanın temel amacı, 1970-2013 dönemleri arasında Türkiye’nin petrol talebinin fiyat ve gelir esnekliklerini tahmin etmek ve petrol fiyatı, petrol talebi ve gelir düzeyi arasındaki nedensellik ilişkisinin yönünü tespit etmektir. Çalışmada tahmin yöntemleri olarak ARDL Sınır Testi yaklaşımı ve Toda-Yamamoto (1995 Granger Nedensellik Testi kullanılmıştır. Yapılan analiz sonucunda değişkenler arasında bir eşbütünleşme ilişkisinin mevcut olduğu gözlemlenmiştir Elde edilen sonuçlara göre, uzun dönemde petrol talebinin fiyat esnekliği -0,17; gelir esnekliği ise 0,51 olarak hesaplanmıştır. Diğer yandan, kısa dönemdeki fiyat esnekliği ise -0,08; gelir esnekliği ise 0,59 olarak tahmin edilmiştir. Elde edilen ampirik sonuçlara göre, petrol talebinin fiyat ve gelir esneklikleri hem uzun dönemde hem de kısa dönemde inelastiktir. Nedensellik Testi sonuçlarına göre ise petrol fiyatından petrol talebine doğru tek yönlü bir nedensellik ilişkisi tespit edilmiştir. Bu sonuçlardan Türkiye’de petrol fiyatı ve gelir düzeyinin petrol talebi üzerinde kısa ve uzun dönemde güçlü bir etkisinin olmadığı, bunun temel nedeninin ise petrolün zorunlu mallar arasında yer almasından kaynaklandığı söylenebilir. ABSTRACT: The primary objective of this paper is estimating price elasticity and income elasticity of oil demand, and causality relationship between variables with respect to Turkish economy for the period of 1970 and 2013. In the study, ARDL Bound Test approach and Toda-Yamamoto (1995 Granger Causality Test are employed as an estimation method. According to bound test analysis, a cointegration relationship is found between variables. Empirical findings show that long-run price and income elasticity of oil demand in Turkey is -0.17 and 0.51 respectively. On the other hand, short-run price and income elasticity of oil demand estimated as -0.08 and 0.59 respectively

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 service station attendants than any other scenario.

For the longer term future, a larger detector could provide an increased yield, boosting the neutrino capture rate by up to a factor of ten. Other, more spectacular, option is to shine the CERN neutrino beam towards a detector a long way off. Such a beam is practically unimpeded by matter and could pass right through the earth. Possible contenders for underground target stations equipped with big detectors are the Italian Gran Sasso laboratory, 730 kilometres south, or Superkamiokande, 8750 kilometres away in Japan. Other major ongoing 'flagship' SPS projects include the NA48 experiment to continue precision measurements on the still unexplained phenomenon of CP violation (March 1992, page 7) and the 'Spin Muon Collaboration' looking to probe the spin structure of the proton and the neutron using high energy muon beams (April 1992, page 21). Both these experiments address important physics issues. While SMC is already taking data, NA48 will not become operational until 1995, but should run then for more than three years. Elsewhere at the SPS, ongoing studies include a programme using hyperon beams, and a study of beauty particles (WA92) which would be hampered once the new neutrino programme starts. The spectroscopy of particles containing light quarks, although far from having solved all outstanding questions, is slowly coming to the end of its SPS career. The WA91 glueball search at the big Omega detector will continue taking data in 1994. The GAMS experiment took its final CERN data last year.

The VITO (Versatile Ion-polarized Techniques Online) project is a new experimental setup at the ISOLDE facility at CERN. VITO is a dedicated beam line for producing laser-induced spin-polarized beams of both, atoms and ions, and it has been commissioned in response to the continuously growing demand for the use of spin-polarized beams. The new VITO beam line is a modification of the formerly existing ultra-high vacuum beam line, connecting ASPIC (Apparatus for Surface Physics and Interfaces at CERN), and it has been under construction since the beginning of 2014. Once fully commissioned, VITO will open up numerous possibilities for carrying out multidisciplinary experiments in the areas of nuclear and solid state physics, fundamental interaction physics and biophysics. In its final stage the VITO beam line will provide three fully independent experimental stations: UHV chamber for material science applications, a β-asymmetry station where highly-polarized ions will be available, and a central open-end station suitable for travelling experiments. The VITO beam line will operate in two different modes providing either beams of spin-polarized atoms or ions, or non-polarized ion beams to all three end stations operating from 10{sup −10} mbar to 50 mbar. Recent experimental campaigns with stable and radioactive beams have allowed for testing VITO’s constituent parts and have demonstrated 96% of ion beam transmission to the collection chamber installed on the central station. The first experimental results obtained with on-line Perturbed Angular Correlation (PAC) spectroscopy using {sup 68m}Cu ion-beams will be briefly discussed.

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

International Nuclear Information System (INIS)

Liu, Ming-Hua; Margaritis, Dimitris; Tourani-Rad, Alireza

2010-01-01

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)

Spatial and temporal variations in Pb concentrations and isotopic composition in road dust, farmland soil and vegetation in proximity to roads since cessation of use of leaded petrol in the UK

International Nuclear Information System (INIS)

MacKinnon, G.; MacKenzie, A.B.; Cook, G.T.; Pulford, I.D.; Duncan, H.J.; Scott, E.M.

2011-01-01

Results are presented for a study of spatial distributions and temporal trends in concentrations of lead (Pb) from different sources in soil and vegetation of an arable farm in central Scotland in the decade since the use of leaded petrol was terminated. Isotopic analyses revealed that in all of the samples analysed, the Pb conformed to a binary mixture of petrol Pb and Pb from industrial or indigenous geological sources and that locally enhanced levels of petrol Pb were restricted to within 10 m of a motorway and 3 m of a minor road. Overall, the dominant source of Pb was historical emissions from nearby industrial areas. There was no discernible change in concentration or isotopic composition of Pb in surface soil or vegetation over the decade since the ban on the sale of leaded petrol. There was an order of magnitude decrease in Pb concentrations in road dust over the study period, but petrol Pb persisted at up to 43% of the total Pb concentration in 2010. Similar concentrations and spatial distributions of petrol Pb and non petrol Pb in vegetation in both 2001 and 2010, with enhanced concentrations near roads, suggested that redistribution of previously deposited material has operated continuously over that period, maintaining a transfer pathway of Pb into the biosphere. The results for vegetation and soil transects near minor roads provided evidence of a non petrol Pb source associated with roads/traffic, but surface soil samples from the vicinity of a motorway failed to show evidence of such a source. - Highlights: → A 10 year study of Pb concentrations and isotopic compositions in farmland. → Soil and vegetation showed no systematic decrease in Pb concentrations over 10 years. → Road dust Pb concentrations fell from 117 mg kg -1 in 2001 to 14.2 mg kg -1 in 2010. → Enhancement of petrol Pb only within 10m of a motorway and 3m of a minor road.

Essa propensão é verificada para posicionamentos essencialmente desfavoráveis às propostas apresentadas pelo IASB, o que implica em considerar que a revisão/substituição do International Financial Reporting Standard -IFRS6 será um processo complexo e sujeito a pressões por parte das empresas petrolíferas para manter o status quo.

In 2013, I was an Einstein Fellow with the U.S. Department of Energy and I was asked by a colleague, working in a senator's office, if I would join him in a meeting with a physicist to "translate" the science into something more understandable. That meeting turned out to be a wonderful opportunity I would never have otherwise had. During the meeting I met Michael Tuts, a physicist who was working on project ATLAS at CERN. Afterwards, I walked with him out of the Senate office building to Union Station and, in parting, he gave me his card and told me that if I were in Geneva that he could help me get a tour of CERN and the LHC.

CERN, the European organization for nuclear research, has just celebrated its fifty years of existence. Its first goal was to counterbalance the migration of physics scientists towards the USA by the creation of a physics laboratory gathering scientists from the different European countries. Today, the CERN's mission has changed and has overcome all the expectations of its founders. In 2008, it will become, with the LHC (Large Hadron Collider), the biggest particle accelerator in the world. The CERN employs about 3000 physicists, engineers, technicians and workers. There is also 6500 people from 80 different countries who use the CERN's facilities during the year. The CERN is controlled by 20 European member states and 6 observer countries, and 20 non-member countries participate to the programs in progress. The CERN's power comes from its international and cosmopolitan spirit. The whole most famous physicists of the world can work together for the progress of science and for a better understanding of matter, of its interactions and of our universe. Two Nobel prices of physics come from the CERN: C. Rubbia and S. Van der Meer in 1983 for the discovery of W{sup +}, W{sup -} and Z{sub 0} bosons, and G. Charpak for the development of particle detectors. One can foresee that the LHC will allow new scientific achievements, like for instance, during experiments for the quest of the famous Higgs boson. It is important also to mention that the CERN has been at the origin of several technological innovations in all technical and engineering domains in the framework of its fundamental physics researches.

Sharing resources@CERN

CERN Multimedia

2002-01-01

The library is launching a 'sharing resources@CERN' campaign, aiming to increase the library's utility by including the thousands of books bought by individual groups at CERN. This will improve sharing of information among CERN staff and users. Until now many people were unaware that copies of the same book (or standard, or journal) are often held not only by the library but by different divisions. (Here Eduardo Aldaz, from the PS division, and Isabel Bejar, from the ST division, read their divisional copies of the same book.) The idea behind the library's new sharing resources@CERN' initiative is not at all to collect the books in individual collections at the CERN library, but simply to register them in the Library database. Those not belonging to the library will in principle be unavailable for loan, but should be able to be consulted by anybody at CERN who is interested. "When you need a book urgently and it is not available in the library,' said PS Division engineer Eduardo Aldaz Carroll, it is a sham...

2017-07-01

This is the first study from Pakistan to report the exposure of petrol filling workers (n = 120) to naphthalene (Nap) and pyrene (Pyr) in relation to their functional capacities and health outcome. A group of non-exposed subjects (controls n = 46) was also recruited for comparison. The perceived health risk of the exposed workers was monitored using a questionnaire based on the self-reporting survey. The observed physical anomalies related to the health disorder included the acidity after meals, eye redness, appetite loss, skin lesions, and dryness of oral cavity, while those related to neurasthenic symptoms included the body aches, energy loss, twitching, fatigue, sleeplessness, fainting, and irritability. Mean Nap level observed in the exposed group (106 μg L -1 ) was significantly correlated (r = 0.49; p Workers exposed for 6 h per day or more had significantly high prevalence of physical disorders (OR = 2.79, 95% CI = 1.28-6.09). Neurasthenic symptoms were found in 65% of the subjects and were associated with years of involvement in job. Ten years or more work duration at petrol pumps could be associated with a substantial development of neurasthenic effects (OR = 2.80, 95% CI = 1.23-6.34). In conclusion, the subjects ascribed the disturbances in physical and neurological behavior to their occupation (petrol filling) and also rated their overall health and functional capacity as poor. To promote health of petrol pump workers, reduction in work hours and provision of masks and gloves could be introduced as occupational health interventions.

In a virtualized environment, contextualization is the process of configuring a VM instance for the needs of various deployment use cases. Contextualization in CernVM can be done by passing a handwritten context to the user data field of cloud APIs, when running CernVM on the cloud, or by using CernVM web interface when running the VM locally. CernVM Online is a publicly accessible web interface that unifies these two procedures. A user is able to define, store and share CernVM contexts using CernVM Online and then apply them either in a cloud by using CernVM Cloud Gateway or on a local VM with the single-step pairing mechanism. CernVM Cloud Gateway is a distributed system that provides a single interface to use multiple and different clouds (by location or type, private or public). Cloud gateway has been so far integrated with OpenNebula, CloudStack and EC2 tools interfaces. A user, with access to a number of clouds, can run CernVM cloud agents that will communicate with these clouds using their interfaces, and then use one single interface to deploy and scale CernVM clusters. CernVM clusters are defined in CernVM Online and consist of a set of CernVM instances that are contextualized and can communicate with each other.

Jarlskog, Cecilia

2014-01-01

CERN, currently the largest organization in the world for particle physics, was founded in 1954. Originally located in Meyrin, at the outskirts of the city of Geneva in Switzerland, it has with time extended into neighboring France. The Theoretical Study Division of CERN, however, was created already in 1952, i.e., before the official inauguration of CERN. It was situated in Copenhagen. Christian Møller [1] was appointed (part-time) as the Director and there were two full time senior staff members, Gunnar Källén and Ben R. Mottelson. While constructing buildings and accelerators were in progress, an international conference was organized by CERN in the city of Geneva. This “CERN Symposium on High Energy Accelerators and Pion Physics”, 11–23 June 1956, attracted about 250 participants from outside CERN, among them at least 18 Nobel Laureates or future Laureates. Unfortunately, the participants from CERN are not listed in the Proceedings [2]. The conference focused on measuring devices such as bubbl...

Art students inspired by CERN will be returning to show their work 9 to 16 October in Building 500, outside the Auditorium. Seventeen art students from around Europe visited CERN last January for a week of introductions to particle physics and astrophysics, and discussions with CERN scientists about their projects. A CERN scientist "adopted"each artist so they could ask questions during and after the visit. Now the seeds planted during their visit have come to fruition in a show using many media and exploring varied concepts, such as how people experience the online world, the sheer scale of CERN's equipment, and the abstractness of the entities scientists are looking for. "The work is so varied, people are going to love some pieces and detest others," says Andrew Charalambous, the project coordinator from University College London who is also curating the exhibition. "It's contemporary modern art, and that's sometimes difficult to take in." For more information on this thought-provoking show, see: htt...

The increased use of petrol bombs as an act of vengeance in Malaysia has heightened awareness for the need of research relating physical evidence found at the crime scene to the perpetrator of the crime. A study was therefore carried out to assess the effectiveness of soot removal techniques on glass fire debris without affecting the fingerprints found on the evidence. Soot was removed using three methods which were brushing, 2 % NaOH solution and tape lifting. Depending on the visibility of prints recovered, prints which were visible after soot removal were lifted directly while prints that were not visible were subjected to enhancement. Glass microscope slides were used in laboratory experiment and subjected to control burn for the formation of soot. Soot was later removed following enhancement of the prints over time (within 1 day, within 2 days and after 2 days). While in simulated petrol bomb ground experiment, petrol bombs were hurled in glass bottles and the fragments were collected. Favorable results were obtained in varying degrees using each soot removal methods. In laboratory testing, brushing and 2 % NaOH solution revealed fingerprints that were visible after removal of excess soot and were lifted directly. As for tape lifting technique, some prints were visible and were successfully lifted while those that were not visible were subjected to super glue fuming for effective fingerprint identification.

Full Text Available About 50% of the 1.4 GeV CERN (European Organization for Nuclear Research, www.cern.ch protons are sent onto targets to produce radioactive beams by online mass separation at the Isotope Separator Online Device (ISOLDE facility, for a wide range of studies in fundamental and applied physics. CERN-MEDICIS is a spin-off dedicated to R&D in life sciences and medical applications. It is located in an extension of the Class A building presently under construction. It will comprise laboratories to receive the irradiated targets from a new station located at the dump position behind the ISOLDE production targets. An increasing range of innovative isotopes will thus progressively become accessible from the start-up of the facility in 2015 onward; for fundamental studies in cancer research, for new imaging and therapy protocols in cell and animal models and for pre-clinical trials, possibly extended to specific early phase clinical studies up to Phase I trials. Five hundred megabecquerel isotope batches purified by electromagnetic mass separation combined with chemical methods will be collected on a weekly basis. A possible future upgrade with gigabecquerel pharmaceutical-grade i.e., current good manufacturing practices (cGMP batch production capabilities is finally presented.

2007-01-01

An analytic investigation of applying Miller cycle to reduce nitrogen oxides (NO x ) 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 NO x formation in engine cylinder. These results in a lower exhaust temperature and less NO x 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 NO x 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 NO x 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 NO x emissions from petrol engine

RSS based CERN Alerter. Information broadcast to all CERN offices.

CERN Multimedia

Otto, R

2007-01-01

Nearly every large organization uses a tool to broadcast messages and information across the internal campus (messages like alerts announcing interruption in services or just information about upcoming events). These tools typically allow administrators (operators) to send "targeted" messages which are sent only to specific groups of users or computers, e/g only those located in a specified building or connected to a particular computing service. CERN has a long history of such tools: CERNVMS€™s SPM_quotMESSAGE command, Zephyr and the most recent the NICE Alerter based on the NNTP protocol. The NICE Alerter used on all Windows-based computers had to be phased out as a consequence of phasing out NNTP at CERN. The new solution to broadcast information messages on the CERN campus continues to provide the service based on cross-platform technologies, hence minimizing custom developments and relying on commercial software as much as possible. The new system, called CERN Alerter, is based on RSS (Really Simpl...

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

Comparative performance of direct injection diesel engine operating on ethanol, petrol and rapeseed oil blends

2009-01-01

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 the biofuel kinematical viscosity, brake mean effective pressure (bmep), brake specific fuel consumption (bsfc) of a diesel engine and its brake thermal efficiency (bte). Addition into RO from 2.5 to 7.5 vol% of ethanol and petrol its viscosity at ambient temperature of 20 deg. C diminishes by 9.2-28.3% and 14.1-31.7%, respectively. Heating up to the temperature of 60 deg. C the viscosity of pure RO, blends ERO2.5-7.5 and PRO2.5-10 further diminishes 4.2, 3.9-3.8 and 3.9-3.6 times. At 1800 min -1 speed, the maximum brake mean effective pressure (bmep) higher up to 1.6% comparing with that of pure RO (0.77 MPa) ensure three agent blends EPRO5-7.5, whereas at rated 2200 min -1 speed, the bmep higher by 5.6% can be obtained when fuelling the engine with blend PRO2.5. Brake specific fuel consumption (bsfc) at maximum torque (240.2 g/kWh) and rated power (234.0 g/kWh) is correspondingly lower by 3.4% and 5.5% in comparison with pure RO when biofuel blends EPRO5 and PRO2.5 are used. The biggest brake thermal efficiency at maximum torque (0.40-0.41) and rated power (0.42-0.43) relative to that of RO (0.39) suggest blends PRO2.5 and EPRO5-7.5, respectively

Economics of a small wind pump system based on estimated petrol and diesel cost savings from use in Northern Nigeria

Directory of Open Access Journals (Sweden)

C. J. Ejieji

2013-08-01

Full Text Available Eleven years of daily wind records were analyzed for the estimation of available wind energy for water pumping at three selected locations in Northern Nigeria, namely Jos, Kano and Sokoto. This formed the basis for investigating the economics of the use of an imported small wind pump under a deregulated energy market environment. The estimated available energy for water pumping at the installation height of 9m was 190 kwh/m2/yr for Jos, 225 kwh/m2/yr for Kano and 348 kwh/m2/yr for Sokoto. The monetary value of the available wind energy was considered as saved energy cost. The saved cost was obtained in terms of the unsubsidized cost of the petrol and diesel that an internal combustion engine (ICE would consume to produce energy equivalent to the available wind energy. At the prevailing interest and inflation rates of 21.96 % and 12.1% respectively, and unsubsidized prices of N 131.32/l and N 140.23/l for petrol and diesel respectively, investment in the wind pump was not found to be economically competitive relative to using a pump with ICE prime mover at the three locations unless the cost of the pump was subsidized. For Sokoto, the estimated subsidy for initial cost of the wind pump required for the investment to be competitive relative to the use of a pump driven by a petrol ICE was 16%. Relative to a pump driven by a diesel ICE, the required subsidy was 24%. The corresponding subsidy estimates for Kano were 48 % and 51 % respectively. For Jos, it was 56% relative to the use of a pump driven by a petrol ICE and 60 % relative to that driven by a diesel ICE. Considering the potential environmental and social and environmental benefits however, subsidy support by government for local manufacturing of the pumps was recommended since shipping cost and custom tariff constituted over 36% of the initial cost of the wind pump.

In its continual tour of CERN Member States, the European Committee for Future Accelerators (ECFA) visited Lisbon, Portugal, on 21-22 April, where it met at the Instituto Superiore Tecnico, a technical university with 9,000 students. Portuguese particle physics is in a particularly healthy situation, having developed considerably following Portugal's admission to CERN in 1985. With support from Brussels, scientific infrastructure has developed rapidly, although the science base has yet to attain the levels seen in larger nations. The 45-strong population of experimentalists in Portugal, including 14 PhDs, represents a 2.5-fold increase since Portugal joined CERN ten years ago and is in line with the goal stated at the time. This successful development of experimental particle physics has benefited much from physicists returning from abroad (mainly France and the UK). The direct result of the efforts of a few individuals (notably J.M. Gago), this splendid achievement provides an excellent role model for new and potential CERN Member States. At present, particle physics represents some 3 0% of all Portuguese physics publications. This very special role (and the financial support it implies) provides a visible target, but one which can be defended as it provides a catalyst for other national scientific developments. The national hub is the Laboratory for experimental high energy physics and related R&D projects (LIP), with centres in Lisbon (Head, J.M. Gago) and Coimbra (Head, A. Policarpo). LIP, with close links to two universities in Lisbon and to the University of Coimbra, has developed into a centre of expertise and training in electronics, computing and software engineering. Present LIP funding is some 2 million Swiss francs/year (70% in Lisbon and 3 0% in Coimbra), covering most of the salaries of the nonuniversity people, the remainder being supported by grants from Portuguese and European programmes.

Israel (along with the US, Japan, Canada, the Russian Federation and India) is one of the CERN non- Member State nations targeted for substantial future participation in CERN's experimental programme, in particular for the LHC proton collider to be built in the 27-kilometre LEP tunnel and which was formally approved by CERN Council in December (January/February, page 1). In keeping with their illustrious scientific traditions, Israeli experimental physicists have collaborated in experiments at many of the world's major high energy Laboratories - Brookhaven, Fermilab and SLAC in the US, and in Europe, DESY, Hamburg, as well as CERN. However CERN, as the geographically closest major Laboratory (as well as the largest), plays a special role for Israeli scientists. At CERN, the advent of preparations in the early 1980s for the experimental programme at the LEP electron-positron collider was the signal for Israeli researchers to mount a concerted effort and contribute to one of the experiments - Opal - at a level comparable to that of major nations. This allowed Israeli teams to participate fully in the planning and construction phase of this branch of Big Science. Underlining this commitment, and to coordinate the various national agencies involved in this aspect of Big Science, in 1983 the Israel Commission for High Energy Physics (ICHEP) was formed. It is currently chaired by David Horn of Tel Aviv. The initial ICHEP/CERN contract established the official CERN/lsrael link under which, in the short-term, teams from three major research centres - the Weizmann Institute, Tel- Aviv University, and Haifa's Technion - contributed to Opal, as the flagship experiment, while providing a framework for longer-term collaboration. (At CERN, Israeli physicists also participate in the NA45 heavy ion experiment and the NA47 Spin Muon Collaboration - SMC.) Opal groups some 320 scientists from 32 research centres in eight countries, and includes a 21-strong Israeli

CERN's technical apprentices during their apprenticeships

CERN Multimedia

Adrian Billet

2004-01-01

CERN starting training apprentices in 1966 at the request of the Geneva authorities. The programme was consolidated with the opening of the training centre in 1971. In recent years CERN has taken on seven new technical apprentices each year (four in electronics, three in physics laboratory work), plus one or two administrative apprentices, such that there always are around 30 apprentices in total at CERN. The programme is highly regarded in Geneva by the authorities, industry, schools and young people, and contributes very positively to CERN's local image. Since the beginning 160 young people have now successfully completed their apprenticeships at CERN. Unlike some other employers, as a general rule CERN does not take on its ex-apprentices as staff; on completing their years at CERN the apprentices usually go on to higher education or are sought after by other employers.

As a consequence of changes in the administrative structure of TIS Division in 1996 and 1997, the Environmental Section was integrated into the TIS Technical Services and Environment Group that also looks after the non-radiation parameters in the CERN releases and environment. However, it remains the duty of the Radiation Protection Group (RP) to define the environmental programme for radiation and radioactivity, and of the leader of RP to report its results both inside and outside CERN. Part I of this Annual Report describes the results of measurements which are relevant for assessing the radiological impact of CERN's activities on the environment and the population living in the vicinity of the CERN sites. Measurements of radioactivity released into the atmosphere and into water, as well as measurements of stray radiation at or near the CERN site boundaries, are reported.

Bianchi-Streit, M.; Blackburne, N.; Budde, R.; Reitz, H.; Sagnell, B.; Schorr, B.; Schmied, H.

1986-01-01

A condensed version is given of CERN report ''Economic utility resulting from CERN contracts'' by the same authors, which attempts to quantify the economic benefit to high technology manufacturing industries involved in CERN contracts, in relation to their sales to CERN. It covers the period 1973 to 1987 and complements an earlier study made in 1973-1975. Interviews were carried out in 166 European firms of which the majority supplied estimates of increased sales and cost savings due to CERN contracts. This ''economic utility'' totals 3107 million Swiss francs (up to the year 1987) compared to sales to CERN in 1973 to 1982 amounting to 748 million Swiss francs in 1982 prices. It is estimated that, by 1987, CERN's high technology purchases made in 1973 to 1982 will have generated economic utility amounting to about 60% of the overall cost of the organization during the same period.

Phenol oxidation of petrol refinery wastewater catalyzed by Laccase

International Nuclear Information System (INIS)

Vargas, Maria Carolina; Ramirez, Nubia E.

2002-01-01

Laccase has been obtained through two different production systems, the first using Pleurotus ostreatus in solid-state fermentation, the second one using Trametes versicolor in submerged culture. Different substrates (by products from yeast, flour and beverage industries) have been evaluated in both systems. Maximum laccase yield with Pleurotus ostreatus (25 u/ml) was obtained in a wheat bran medium. The maximum enzyme concentration level using Trametes versicolor (25 u/ml) was achieved in a submerged system, containing 10% vinasse, 4,5% wheat bran and 0,2% molasses per liter of waste. Culture filtrate extracted from Pleurotus ostreatus was used to remove phenol from wastewater. The enzymatic treatment is effective over a wide pH and temperature range. The Laccase treatment has been successfully used to dephenolize industrial petrol refinery wastewater. The advantage of Laccase dephenolization is that this enzyme uses molecular oxygen as an oxidant

Open Hardware at CERN

CERN Multimedia

CERN Knowledge Transfer Group

2015-01-01

CERN is actively making its knowledge and technology available for the benefit of society and does so through a variety of different mechanisms. Open hardware has in recent years established itself as a very effective way for CERN to make electronics designs and in particular printed circuit board layouts, accessible to anyone, while also facilitating collaboration and design re-use. It is creating an impact on many levels, from companies producing and selling products based on hardware designed at CERN, to new projects being released under the CERN Open Hardware Licence. Today the open hardware community includes large research institutes, universities, individual enthusiasts and companies. Many of the companies are actively involved in the entire process from design to production, delivering services and consultancy and even making their own products available under open licences.

These parameters are based on the so-called purple, yellow and red books (Dutch books on QRA employed in other countries of the world too). Safety distances in the Netherlands will be compared to one another for petrol, diesel, natural gas and LPG filling stations. (Author)

CERN safety reaches out to medicine

CERN Document Server

2001-01-01

What do CERN and other scientific organizations like ESA and ESO have in common with neurosurgery and airlines? At first sight, not much. But all require sound safety management. CERN's expertise in this field was recently highlighted when two CERN engineers were invited to talk at an international conference on Quality Management and Risk Control in Neurosurgery.CERN has long been recognised as a centre of excellence in physics, and its spin-offs in fields such as medicine have been widely hailed. But increasingly, the Laboratory's expertise in the management of large international collaborations is also being recognised. Contacts between CERN and organizations like ESA and ESO, as well as with industry, bear witness to this fact. One recent example comes from Airbus Industrie, which organized a meeting in 1998 with CERN to compare notes on project management, safety, and quality assurance. Safety management is a recognised speciality in the field of project management and at CERN, TIS and the safety offici...

2015-01-01

For five decades, the CERN Bulletin has been a staple of the Organization. As CERN has grown as a laboratory and a community, the Bulletin has been there to cover each development as it happens. In honour of the publication's 50th anniversary, we're taking a trip through CERN’s history via the headings and hidden corners of its internal newsletter.     It's 1965 and CERN - now 11 years old - has matured from a simple lab to a fledgling community. While news could once spread in a single afternoon, CERN's growth necessitated a new approach to the sharing of internal information. Meanwhile, the CERN Courier - the only publication in town - was approaching a more global physics audience – an audience for whom CERN road closures were not breaking news. And so, in March 1965, the Weekly Bulletin was born. What was meant as a simple newsletter of events and internal announcements quickly developed into a wider source of news about CERN....

The paper examines the future of CERN, with respect to its proposed research programme and its need to save money. Proposals concerning what accelerators CERN should build for the future are outlined; machines such as the Large Hadron Collider and the CERN Linear Collider have been proposed. Experimental expectations for the first Large Electron Positron (LEP) collider (now close to completion) are briefly described, along with the experimental investigations for the second phase of operation of LEP where modifications will increase the machine's energy. Criticisms of CERN's management by its governing body are also discussed. (UK)

CERN, the US and the W

CERN Document Server

Crease, Robert P

2004-01-01

In 1983, CERN physicists discovered the W boson earning them the first Nobel prize. This discovery served as the turning point for CERN from the point of view of the self-confidence of its physicists, the confidence of its fund-raisers, and its reputation in the US. However, this feat did not come as easy for CERN. Rivalry with the US revealed complexities. Nevertheless in the end, CERN physicists became the more successful. Recognizing this, US physicists agreed to collaborate with CERN physicists. Today, there is no more political competition over accelerators between the two groups. (Edited abstract).

Certification and commissioning of barrel stations for the ATLAS muon spectrometer

CERN Document Server

Zimmermann, S

2006-01-01

The muon spectrometer of the ATLAS experiment, which is scheduled to commence data taking at the Large Hadron Collider, LHC at CERN in 2007, comprises more than a thousand muon stations, which have the double purpose of triggering on high-p/sub t/ muon tracks as well as providing precise trajectory reconstruction. While monitored drift tube chambers are used for track reconstruction in all of the muon spectrometer except for a region close to the beam pipe in forward direction, two different technologies are used for triggering, resistive plate chambers in the barrel region and thin gap chambers in the end-caps. Both have in common that the ATLAS geometry allows only limited accessibility after chambers are installed in the detector. A thorough testing and certification prior to installation is therefore crucial. This paper reviews the test procedure at CERN for barrel chambers of type BO and BM, i.e. of stations for which a drift chamber is coupled with one or two resistive plate chambers. The final certific...

The SPS Target Station for CHORUS and NOMAD Neutrino Experiments

CERN Document Server

Péraire, S; Zazula, J M

1996-01-01

A new SPS target station, T9, has been constructed for the CHORUS and NOMAD neutrino experiments at CERN. The heart of the station is the target box : 11 beryllium rods are aligned in a cast aluminium box ; they are cooled by a closed circuit helium gas with adjusted flow to each rod. The box is motorised horizontally and vertically at both ends, to remotely optimise the secondary particle production by aligning the target with the incident proton beam. Radiation protection around the station is guaranteed by more than 100 tons of shielding material (iron, copper, marble). This presentation describes briefly the various components of the target station ; it emphasises particularly the thermal and mechanical calculations which define a safe maximum beam intensity on the beryllium rods. Over the first two years of successful operation, the station has received more than 2€1019 protons at 450 GeV/c, with intensity peaks of 2.8€1013 protons per machine cycle.

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

Restructuring the Water Supply at CERN

CERN Document Server

Nonis, M

1999-01-01

The CERN water network is the result of continuous extensions made to meet the different needs of the experiments and accelerators. Several studies concerning the current water consumption and the foreseen needs for the running of the new accelerators show a need to optimize the network and, where possible, reduce the consumption. Site construction works will begin in February 1999 and will continue until 2003; important modification works on the water network will only be possible during the shutdown for the dismantling of LEP. This paper will present the technical outlines and will report the status of the project. ST Division is involved in reorganizing the demineralized and primary cooling water circuits for the accelerators while Services Industriels de Genève (SIG) will be responsible for the works on pumping stations and on water networks.

2004-12-01

Full Text Available

Occupational exposure to benzene in petrol pump attendants and in mechanics was studied by examining the benzene content in both the air breathed and in the urinary metabolite trans,trans-muconic acid (t,t-MA. Thirty petrol pump attendants and thirty mechanics (as exposed workers and thirty adult male office workers (as non exposed workers were involved in the study. Measures were taken at the begin and at the end of the working shifts.

 The benzene concentrations in the breathing air samples varied from 2 to 88 μg m-3, lower than the EU acceptable limit for occupational environment. The average urinary t,t-MA in the petrol pump attendants at the begin and at the end of the working shifts ranged between 133 ± 69 and 255 ± 174 μg g-1 creatinine and in the mechanics between 204 ± 139 and 300 ± 211 μg g-1 creatinine, respectively.

In all the participants the mean levels of urinary t,t-MA at the end of the working shifts were significantly higher than those at the beginning. In the exposed workers mean levels of urinary t,t-MA were significantly higher than in those of the non-exposed workers. The influence of the smoking was demonstrated by the urinary t,t-MA levels in smoking non-exposed subjects.

Full text: Arecent arrival at CERN is a cryostat built under the auspices of thelnternational Science and Technology Center (ISTC), a programme funded by the European Union, Japan, Russia, and the US which aims to promote the integration of former Soviet Union scientists and industry into global research and development activities. The new cryostat, built by Moscowbased Krunichev Enterprises, better known for its involvement in the ''Proton'' space rocket and the ''Mir'' space station, will form a vital part of the NA48 experiment at the SPS synchrotron. NA48, a Cagliari/Cambridge/CERN/ Dubna/Edinburgh/Ferrara/Mainz/Orsay/Perugia/Pisa/Saclay/Siegen/ Turin/Vienna collaboration, aims to study the small asymmetry in the properties of matter and antimatter known as CP violation, and should be fully ready to collect data next year. Through its links with Dubna's Joint Institute of Nuclear Research (JINR), near Moscow, NA48 has launched a number of initiatives designed to involve Russian physicists and industry in the experiment. The bargain 22 tonnes of krypton for NA48's energy-measuring calorimeter were manufactured at a specially- built factory in Russia. INTAS, the European Union-backed scheme for the promotion of cooperation with former Soviet Union scientists, provides funds for Dubna physicists to visit Western Europe. INTAS will also provide computing and networking infrastructure allowing the Russian physicists to participate fully in NA48's programme. As well as the cryostat, NA48's collaborating institutes have placed other orders with Russian suppliers. INFN Pisa has ordered 14,000 electrical feed-though contacts from the Budker Institute in Novosibirsk, whilst Saclay has placed contracts elsewhere for vacuum and other equipment. The new cryostat forms part of a joint project of INFN Pisa and CERN, involving scientists from Dubna, Edinburgh, and Saclay. The Russian part was built by Krunichev

Industrial Activity at CERN

CERN Document Server

Kowalik, G

2000-01-01

The decrease in the number of CERN staff creates the need for optimization of the non-core, infrastructure-related activities. An industrial, service-orientated approach has long been considered as an appropriate way to cope with the problem of diminishing resources. This paper presents industrial and service activity issues at CERN based on the experience of the exploitation of the power network. The most important problems linked to the application of the industrial approach to the exploitation of equipment in the CERN research environment are covered. These include the interface between accelerators and electrical exploitation services, external and internal regulations, sharing of responsibility between CERN staff and external contractors, continuous modification of clients' requirements, the balance between the cost of accelerator downtime versus the cost of infrastructure upgrade. A benchmarking through a comparison with a big industrial manufacturer is followed by recommendations for possible improveme...

2012-01-01

Cutting-edge research requires a constantly high performance of the computing equipment. At the CERN Computing Centre, computers typically need to be replaced after about four years of use. However, while servers may be withdrawn from cutting-edge use, they are still good for other uses elsewhere. This week, 220 servers and 30 routers were donated to the Kwame Nkrumah University of Science and Technology (KNUST) in Ghana.   “KNUST will provide a good home for these computers. The university has also developed a plan for using them to develop scientific collaboration with CERN,” said John Ellis, a professor at King’s College London and a visiting professor in CERN’s Theory Group.  John Ellis was heavily involved in building the relationship with Ghana, which started in 2006 when a Ghanaian participated in the CERN openlab student programme. Since 2007 CERN has hosted Ghanaians especially from KNUST in the framework of the CERN Summer Student Progr...

The connection between CERN and space is tangible this week, as former CERN Fellow and ESA astronaut Christer Fuglesang begins the second week of his mission on space shuttle flight STS-128. I had the pleasure to meet Christer back in October 2008 at an IEEE symposium in Dresden, and he asked me whether we could give him something related to CERN for his official flight kit. We thought of caps and tee-shirts, but in the end decided to give him a neutralino as a symbol of the link between particle physics and the science of the Universe. Neutralinos are theoretical particles that the LHC will be looking for, and if they exist, they’re strong candidates for the Universe’s dark matter. Christer’s neutralino is just a model, of course, escaped from the particle zoo, but what better symbol of the connectedness of science? Christer Fuglesang is not the only link CERN has with the space shuttle programme. We’ve recently learned that...

2010-01-01

This paper addresses the control optimization of a 4.5 K refrigerator used in the cryogenic system of the Large Hadron Collider (LHC) at CERN. First, the compressor station with the cold-box have been modeled and simulated under PROCOS (Process and Control Simulator), a simulation environment developed at CERN. Next, an appropriate parameter identification has been performed on the simulator to obtain a simplified model of the system in order to design an Internal Model Control (IMC) enhancing the regulation of the high pressure. Finally, a floating high pressure control is proposed using a cascade control to reduce operational costs.

Over thirty sites for the tours have already been identified, including the experiment halls, the assembly halls for the LHC detectors and magnets as well as the computer centre and the fire station. With a programme offering tours, talks, a play on a scientific theme and a variety of workshops, there will be something for everybody. A number of evening tours will be organised specifically for the inhabitants of Cessy, St Genis, Meyrin and Ferney Voltaire, where the experiment halls for CMS, ALICE, ATLAS and LHCb are respectively located. An area will even be set aside with stimulating games to enterta...

Neutrinos at CERN

CERN's long and distinguished neutrino tradition began in 1958 at the then new 500 MeV synchrocyclotron (SC) with the first observation of the decay of a charged pion into an electron and a neutrino. At that time, the first ideas on the special (vector/axial vector) structure of the weak interactions had been put forward by Feynman and Gell-Mann and by Marshak and Sudarshan, but the continual non-observation of that charged pion decay was holding up progress. This decay is only one part in ten thousand, and is masked by the dominant muon-neutrino channel. A special telescope was built to pick up the high energy electrons from the pion decay. In 1962 came another SC neutrino success, with the first measurement of the decay of a charged pion into a neutral one, with emission of an electron and a neutrino. Meanwhile the main thrust of CERN's neutrino effort was taking shape at the PS. By the close of 1960, CERN had decided to attack neutrino physics using several detectors - a 1m heavy liquid bubble chamber from Andre Lagarrigue's team in Paris, a CERN 1 m heavy liquid bubble chamber, and a hybrid chamber/counter from a group led by Helmut Faissner

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

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 m 3 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 m 2 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 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
