    Cruising timber is ordinarily a job of sampling, in which the quantity of timber on a tract is estimated from the quantity on a part of the tract. The difficulty is to determine what part (per cent) of the tract should be sampled to attain a given level of accuracy. This article gives a rule-ofthumb that can be applied with fair reliability to most Southern forests....

    CentOS is just like Red Hat, but without the price tag and with the virtuous license. When belts have to be tightened, we want to read about an OS with all the features of a commercial Linux variety, but without the pain. The Definitive Guide to CentOS is the first definitive reference for CentOS and focuses on CentOS alone, the workhorse Linux distro, that does the heavy lifting in small and medium-size enterprises without drawing too much attention to itself. *Provides tutorial and hands-on learning but is also designed to be used as a reference*Bases all examples on real-world tasks that re

    To compare the clinical effectiveness and adverse events for 3 per cent boric acid in 70 per cent alcohol versus 1 per cent clotrimazole solution in the treatment of otomycosis. A total of 120 otomycosis patients were randomly assigned to receive either 1 per cent clotrimazole solution (intervention group) or 3 per cent boric acid in 70 per cent alcohol (control group) at the Khon Kaen Hospital ENT out-patient department. Treatment effectiveness was determined based on the otomicroscopic absence of fungus one week after therapy, following a single application of treatment. After 1 week of treatment, there were data for 109 participants, 54 in the clotrimazole group and 55 in the boric acid group. The absolute difference in cure rates between 1 per cent clotrimazole solution and 3 per cent boric acid in 70 per cent alcohol was 17.9 per cent (95 per cent confidence interval, 2.3 to 33.5; p = 0.028) and the number needed to treat was 6 (95 per cent confidence interval, 3.0 to 43.4). Adverse events for the two agents were comparable. One per cent clotrimazole solution is more effective than 3 per cent boric acid in 70 per cent alcohol for otomycosis treatment.

    The objective of this study was to describe and compare the efficacy and duration of topical anaesthesia induced by 2 per cent lidocaine (L), 0.5 per cent bupivacaine (B) and 1 per cent ropivacaine (R) in the dog using 24 clinically healthy beagles with normal ocular examination. Dogs were randomly divided into three groups: 2 per cent lidocaine (n=8), 0.5 per cent bupivacaine (n=8) and 1 per cent ropivacaine (n=8). The baseline corneal touch threshold (CTT) was measured using a Cochet-Bonnet aesthesiometer. Following baseline CTT measurement, a single drop of the assigned anaesthetic was applied to each eye and the CTT was measured bilaterally within one minute after administration and every five minutes until the basal CTT value was restored. Data were analysed with non-parametric analysis of variance models and Dunnet's test for post hoc analysis. One per cent ropivacaine was the most effective drug (LCTTmax=3 cm, BCTTmax=2 cm, RCTTmax=0 cm; Pper cent ropivacaine had the maximal and quickest anaesthetic effect. This drug could be used for specific diagnostic procedures where quick and short, but effective, corneal anaesthesia is needed.

    2015-01-01

    The present work aimed to evaluate, through ten different studies, the therapeutic efficacy of a new pour-on formulation, containing 1.5 per cent ivermectin +0.5 per cent abamectin, against parasites of cattle. Results obtained on trials against Rhipicephalus (Boophilus) microplus showed that the pour-on combination of 1.5 per cent ivermectin +0.5 per cent abamectin obtained superior efficacy indexes against this ectoparasite, when compared with formulations containing 0.5 per cent ivermectin, 1 per cent ivermectin and the combination of 1 per cent abamectin +20 per cent levamisole. The results of efficacy of the ivermectin+abamectin and the 0.5 per cent ivermectin against Haematobia irritans were similar. Against Cochliomyia hominivorax larvae, all pour-on formulations tested (1.5 per cent ivermectin +0.5 per cent abamectin, 0.5 per cent ivermectin and 0.5 per cent abamectin), as well as 1 per cent doramectin administered subcutaneously, were considered ineffective. Cattle medicated with 1.5 per cent ivermectin +0.5 per cent abamectin, pour-on, remained free from parasitism by Dermatobia hominis larvae during 42 days (96 per cent efficacy), while values superior to 90 per cent were obtained by 0.5 per cent ivermectin (92 per cent) and 0.5 per cent abamectin (93 per cent) until the 42nd and 35th days post treatment, respectively. Against Haemonchus placei and Oesophagostomum radiatum, the pour-on of ivermectin+abamectin showed better efficacy than the 0.5 per cent ivermectin and 0.5 per cent abamectin. As to Cooperia punctata, there was no difference regarding efficacy results obtained by the avermectins combination and abamectin. The pour-on combination of 1.5 per cent ivermectin +0.5 per cent abamectin obtained high efficacy against R. (B.) microplus, D. hominis and some species of cattle gastrointestinal helminths when compared with formulations of 0.5 per cent ivermectin and 0.5 per cent abamectin administered through the same route.

  10. Strong sales growth in 2006: + 21 per cent

    2007-07-01

    Paris, February 14, 2007 - The Gaz de France group today reported record consolidated sales of euro 27,642 million in 2006, up 21 per cent compared with 2005. Under average weather conditions and comparable accounting methods, sales increased by 24 per cent versus 2005. This growth results primarily from an overall increase in European energy prices notwithstanding the slight decrease in prices towards the end of the year. The group also benefited from an increase in volumes and from the integration of new operations. After a colder first half of the year compared to that of the previous year, the autumn of 2006 was particularly warm. This had a negative impact on sales growth (there was a 12 billion kWh decrease between 2005 and 2006). The sales generated by the group's international activities increased by 33 per cent to a total of euro 10,839 m in 2006 and now account for almost 40 per cent of the group's overall sales. In this context, the group confirmed at the board meeting held on January 23, 2007 that it would reach the targets set for 2006, namely: - Growth in EBITDA above 20 per cent, e.g. in excess of euro 5 billion, - Net income of more than euro 2.2 billion.

    1997-01-01

    A recent survey of public opinion has shown that 85 per cent of the public view their electric utility company favourably. This represents a 10 per cent increase over last year. A survey of 4,090 Canadians was conducted which looked at the perceptions of the value of electricity services compared to telephone, natural gas, banking, and home insurance services. The study showed that Canadian electric utility companies are viewed as positively as the telephone companies and almost as favourably as the banks. Some 71 per cent of respondents reported that the value they receive from their electric utility is excellent or good. Lower prices, better customer services and increased research into alternative power sources were among the benefits that Canadians perceive would result from a more competitive electricity sector. Some misgivings about deregulation included a belief that there would be less attention to environmental concerns and more outages. Four per cent of the respondents said they would 'definitely' switch to an alternative supplier of electricity, while 25 per cent said they would 'probably' switch to an alternative supplier of electricity. 2 tabs

  16. Ten per cent polarized optical emission from GRB 090102.

    The nature of the jets and the role of magnetic fields in gamma-ray bursts (GRBs) remains unclear. In a baryon-dominated jet only weak, tangled fields generated in situ through shocks would be present. In an alternative model, jets are threaded with large-scale magnetic fields that originate at the central engine and that accelerate and collimate the material. To distinguish between the models the degree of polarization in early-time emission must be measured; however, previous claims of gamma-ray polarization have been controversial. Here we report that the early optical emission from GRB 090102 was polarized at 10 +/- 1 per cent, indicating the presence of large-scale fields originating in the expanding fireball. If the degree of polarization and its position angle were variable on timescales shorter than our 60-second exposure, then the peak polarization may have been larger than ten per cent.

    Basu (2006) argues that the prevalence of 99 cent prices in shops can be explained with rational consumers who disregard the rightmost digits of the price. This bounded rational behaviour leads to a Bertrand equi- librium with positive markups. We use data from an Austrian price com- parison site and find results highly compatible with Basu's theory. We can show that price points - in particular prices ending in 9 - are preva- lent and have significant impact on consumer demand. Moreover, the...

    The authors report a study which aimed at determining for different uranium molybdenum alloys and with respect to their molybdenum content a polishing method which allows a relatively simple grain examination in the as-cast condition, an as perfect as possible resolution of eutectic decompositions, and the appropriate conditions to highlight structures (beta-alpha and gamma-alpha martensite transformations, beta phase retention and decomposition, transient structures, eutectoid decomposition, and so on). Alloys differ by their molybdenum content: from 0.5 to 1 per cent wt, 1.5 to 3 per cent wt, 5 to 10 per cent wt

    The following properties have been determined in the new cast state of uranium alloys containing 0.5-1-1.8-2 and 3.5 per cent of molybdenum: micro-graphical aspect, crystalline structure, thermal expansion, the mechanical characteristics, behaviour when subjected to cyclic temperature variations, and heat treatment. The transformation curves have been established for continuous cooling at rates varying between 2.5 and 200 deg. C per minute, using a dilatation method for the alloys containing 1.0, 2.0 and 3.0 per cent Mo. T.T.T. curves have been traced for 0.5 and 1.0 per cent Mo alloys and the Ms points determined for alloys containing 2.0 and 3.0 par cent Mo. In this way it has been possible to show the different results of transformation, brought about either by nucleation and diffusion or by shear - the alloy containing 1 per cent Mo, give two martensites α' and α'' and the alloys containing 2 and 3 per cent Mo give one martensite with a band structure.

  3. 100 per cent of renewable energy in France: a 'delusional' project?

    International Nuclear Information System (INIS)

    Danielo, Olivier; Thouverez, Pierre

    2016-01-01

    After having mentioned publications by researchers of the MIT and of the University of Stanford stating that the world could face its energetic needs with a 100 per cent WWS (wind water sun) system, the author comments reactions of one of these researchers about the French case: the 1384 TWh required could be distributed in 57 per cent of wind energy, 37 per cent of solar and 5 per cent of hydroelectricity. The author also evokes assessments performed by the ADEME on the potential of ground-based solar energy. According to the American study, 2.5 per cent of the French national surface would be enough for France to become entirely renewable. The author comments the differences between ADEME's and American assessments. He also discusses the issue of negative growth in relationship with these perspectives of development of renewable (and notably solar) energies. He proposes then an overview of various visions for the future, and outlines the difficulties for some so-called experts to change their approach

    U-Pu-Nb alloys containing 20 wt per cent Pu and 10 - 20 - 30 - 40 - 50 or 60 wt per cent Nb have been studied principally to determine the feasibility of their use as fuel element. The fabrication, casting and homogenisation presented certain difficulties due specially to niobium. The transformation temperatures, thermal expansion coefficients and nature of phases have been determined by thermal analysis, dilatometry, micrography and X Rays diffraction. For similar compositions, U-Pu-Mo and U-Pu-Nb alloys have many common points concerning the presence of zeta phase (up to 40 wt per cent Nb), the coefficients of expansion, the good behaviour during thermal cycling and the good resistance to air oxidation in spite of zeta phase. In consequence, irradiation tests in EL 3 reactor (Saclay) will be carried out in the near future. (authors) [fr

    The ForCent forest ecosystem model was developed by making major revisions to the DayCent model including: (1) adding a humus organic pool, (2) incorporating a detailed root growth model, and (3) including plant phenological growth patterns. Observed plant production and soil respiration data from 1993 to 2000 were used to demonstrate that the ForCent model could accurately simulate ecosystem carbon dynamics for the Oak Ridge National Laboratory deciduous forest. A comparison of ForCent versus observed soil pool {sup 14}C signature ({Delta} {sup 14}C) data from the Enriched Background Isotope Study {sup 14}C experiment (1999-2006) shows that the model correctly simulates the temporal dynamics of the {sup 14}C label as it moved from the surface litter and roots into the mineral soil organic matter pools. ForCent model validation was performed by comparing the observed Enriched Background Isotope Study experimental data with simulated live and dead root biomass {Delta} {sup 14}C data, and with soil respiration {Delta} {sup 14}C (mineral soil, humus layer, leaf litter layer, and total soil respiration) data. Results show that the model correctly simulates the impact of the Enriched Background Isotope Study {sup 14}C experimental treatments on soil respiration {Delta} {sup 14}C values for the different soil organic matter pools. Model results suggest that a two-pool root growth model correctly represents root carbon dynamics and inputs to the soil. The model fitting process and sensitivity analysis exposed uncertainty in our estimates of the fraction of mineral soil in the slow and passive pools, dissolved organic carbon flux out of the litter layer into the mineral soil, and mixing of the humus layer into the mineral soil layer.

    Danielo, Olivier; Thouverez, Pierre

    2017-01-01

    The author reports and comments the content of the International Energy Storage Conference held in Dusseldorf in March 2017 which addresses the possibility of reaching a 100 per cent renewable energy, the possible percentage of solar-wind energy which could be integrated into the grid, the storage and back-up needs, whether Power-to-Gas is unavoidable, and whether electric cars are an obstacle or an opportunity. By referring to various contributions, the author outlines that the complementarity of solar and wind energies allows a massive reduction of storage and back-up needs, that it is possible of reach 90 per cent of solar-wind by using intra-day storage (the remaining 10 per cent can be obtained through conventional back-up), that using Power-To-Gas to valorise solar-wind production surpluses is not a viable solution, that the existing gas network will be useful for the back-up. He also outlines the high potential of development of batteries for electric vehicles, and the high interest of new batteries (compared to those based on hydrogen) to reduce pressure on water resources

    Biolarvicides may offer alternatives to chemical larvicides as these are known to be safe to environment and selective against the target species. However, only a limited number of biolarvicides have been approved for mosquito larval control. In the current study, a new formulation of spinosad, 20 per cent emulsifiable concentrate (EC) was tested for its efficacy against Culex quinquefasciatus, in comparison to its 12 per cent suspension concentrate (SC). Spinosad 20 per cent EC was tested against Cx. quinquefasciatus immature at 25, 50, 100 and 150 mg active ingredient (ai)/m [2] in cesspits, drains and abandoned wells in comparison with spinosad 12 per cent SC at the optimum field application dosage of 50 mg ai/m [2] . The 20 per cent EC caused 90-100 per cent reduction of pupal density for 7-14 days in cesspits, 10-17 days in drains and 14-30 days in abandoned wells at all dosages tested. At lower dosages of 25 and 50 mg ai/m [2] , >90 per cent reduction of pupal density was observed for one week in cesspits and street drains and for two weeks in abandoned wells. The effective duration of control provided by the higher dosages, 100 and 150 mg ai/m [2] was 1.4 to 2 times greater than the lower dosages, 25 and 50 mg ai/m [2] . The findings showed that the spinosad 20 per cent EC can be used for larval control against Cx. quinquefasciatus, at the dosage of 25 mg ai/m [2] at weekly interval in cesspits and drains and at fortnightly interval in abandoned wells. Spinosad 20 per cent EC could be one of the options to be considered for larval control under integrated vector management.

    In order to study the transformation kinetics of U-Zr alloys with a Zr content of 6 per cent in weight, the authors searched for a slow enough electrolytic polishing bath, and for an attack and examination method to highlight martensite structures produced by austempering and water tempering, and ultra-fine decomposition structures obtained by austempering. The authors explain the choice of a perchloric-butyl glycol polishing bath, of an examination under polarized light or normal light after appropriate attacks. These studies are reported for annealed alloys, and for processed alloys with martensite or ultra-fine decomposition structures [fr

    One of the key questions in observational cosmology is the identification of the sources responsible for ionization of the Universe after the cosmic 'Dark Ages', when the baryonic matter was neutral. The currently identified distant galaxies are insufficient to fully reionize the Universe by redshift z ≈ 6 (refs 1-3), but low-mass, star-forming galaxies are thought to be responsible for the bulk of the ionizing radiation. As direct observations at high redshift are difficult for a variety of reasons, one solution is to identify local proxies of this galaxy population. Starburst galaxies at low redshifts, however, generally are opaque to Lyman continuum photons. Small escape fractions of about 1 to 3 per cent, insufficient to ionize much surrounding gas, have been detected only in three low-redshift galaxies. Here we report far-ultraviolet observations of the nearby low-mass star-forming galaxy J0925+1403. The galaxy is leaking ionizing radiation with an escape fraction of about 8 per cent. The total number of photons emitted during the starburst phase is sufficient to ionize intergalactic medium material that is about 40 times as massive as the stellar mass of the galaxy.

  13. Raising the bar on the foreign portfolio to 25 per cent: Strategic implications for South African investors

    Full Text Available Regulation 28 of the Pension Funds Act now permits an increased allocation of 25 per cent to foreign investments. The regulation previously only permitted a 20 per cent allocation. Establishing the optimal foreign allocation for South African portfolio managers given the 25 per cent upper bound is an important consideration for strategic portfolio planning. In this paper we consider two methodological approaches to establish a strategic foreign allocation weight. Our first approach considers the strategic role of foreign investment in South African global balanced portfolios by using a mean-variance efficient frontier framework over a long-term period. We also implement a second assessment methodology that utilises a nonparametric procedure. Both the mean-variance and the non-parametric methodology yield compelling evidence for the foreign allocation to be set at the maximum allowable bound of 25 per cent.

    A qualitative overview of Shell Canada's Scotford refinery was presented. The Scotford refinery is the only refinery in North America designed to run on 100 per cent synthetic crude. As a result, Scotford has a unique configuration and has faced some unique problems. Some of the challenges met in converting synthetic crude to today's products are described. The refinery's unique configuration is centered around a large hydrocracker and has high yield flexibility. The major units of the refinery are the crude unit, hydrocracker, naphtha hydrotreater and reformer, the aromatics complex, the distillate hydrogenator and the hydrogen plants. The refinery products include low sulphur gasoline, jet fuel and diesel fuel. Other products include LPG, FCC feed, benzene and solvents. Several process problems have been experienced at the Scotford refinery including hydrodenitrification of synthetic gasoline, PCA fouling, particulate fouling, crude unit fouling, and distillate lubricity. Solutions have been devised for most of these problems. 3 figs

    A simulation technique for the loss-of-coolant failure analysis of light-water-cooled nuclear reactor is described. It has been used to analyze transient processes during a hypothetical accident and to estimate the effectiveness of built-in safety systems. The model PMK-NHV was established for these types of simulation in the Paks Nuclear Power Plant, Hungary. The first test on this simulation facility is described: a 7.4 per cent cold leg break from full power covering the blowdown phase of the accident. The pre-test analysis using the RELAP4/mod6 computer code, the evaluation of the measured data, the interpretation of the test results and the post-test calculations are presented. The work was performed within the IAEA Standard Problem Exersice (SPE). (R.P.)

  17. World record of PV solar competitiveness: 2.6 cent per KWh in Dubai

    2016-01-01

    A proposition of 2.99 cent per KWh of solar photovoltaic power has been made to the local electric power operator (DEWA) by a Saudi and Spanish venture, and DEWA is now to examine technical and commercial aspects to choose between this proposition and those made by a Chinese company (JinkoSolar), a Saudi and American venture, Engie and EDF. The author of this article outlines that such a competitive trend can be noticed in other countries (in the Emirates, in Mexico, in Peru, in the USA). The competitiveness record in Dubai is due to a low labour cost and to an optimal sunning. The author then discusses the fact that solar PV in France is now nearly as cheap as nuclear, and the main consequence of this trend: nuclear will never be competitive with respect to solar energy any longer. He finally evokes Wattway, the project of a solar road in France, and quotes various reactions and opinions about it

    The specifications on Fast Breeder Reactor (FBTR) fuel pellets have two apparently contradictory requirements viz. (1) formation of homogeneous solid between UO 2 and PuO 2 which can only be achieved by high temperature sintering and (2) density of sintered pellets in the range of 92 ± 1 per cent T.D. which is normally achieved by low temperature sintering. Deactivation of starting powders under CO 2 or addition of volatile pore formers to the powders are the two methods which have been developed for lowering the denity of the pellets without reducing the sintering temperature. Two alternative fabrication routes utilizing these processes for manufacturing of FBTR pellets are described in this report. (author)

  19. Fifty per cent reduction in solution gas flaring : a report to the Saddle Hills Awareness Committee

    International Nuclear Information System (INIS)

    1999-01-01

    Information by the Alberta Energy Company to the Saddle Hills Awareness Committee (SHAC) regarding company operations in the West Peace River Arch of the western Canadian Sedimentary Basin in northwest Alberta is presented, the purpose being to bring the Committee up-to-date, and respond to concerns about the health effects of sour gas emissions. The SHAC represents citizens who are concerned about issues relating to sour gas emissions. AEC West, a business unit of Alberta Energy Company, operates two sour gas processing plants, one sweet gas plant and three sour oil batteries in the Grande Prairie area. AEC's gas plants are connected by pipelines and process petroleum and natural gas products from approximately 200 oil and gas wells. The H 2 S content of the natural gas being processed by AEC's various plants ranges from trace amounts to 11 per cent. Activities at AEC's Hythe plant and at the Sexsmith plant, and the company's gas storage project are briefly reviewed. An analysis is included of the role that flaring plays in the petroleum and natural gas industry, emphasizing AEC West's efforts during 1997 to reduce solution gas flaring volumes from single well oil batteries by 50 per cent. Other AEC West environmental protection initiatives include the preliminary regional airshed study sponsored by the company which resulted in part from SHAC feedback and in part from the innovative approach of AEC employees. AEC West established the industry's first Ombudsman to provide a problem resolution focus on landowner complaints and introduced a policy of making available solution gas that would eventually be flared to industrial colleagues, free of charge

    Observations of the cosmic microwave background indicate that baryons account for 5 per cent of the Universe's total energy content. In the local Universe, the census of all observed baryons falls short of this estimate by a factor of two. Cosmological simulations indicate that the missing baryons have not condensed into virialized haloes, but reside throughout the filaments of the cosmic web (where matter density is larger than average) as a low-density plasma at temperatures of 10(5)-10(7) kelvin, known as the warm-hot intergalactic medium. There have been previous claims of the detection of warm-hot baryons along the line of sight to distant blazars and of hot gas between interacting clusters. These observations were, however, unable to trace the large-scale filamentary structure, or to estimate the total amount of warm-hot baryons in a representative volume of the Universe. Here we report X-ray observations of filamentary structures of gas at 10(7) kelvin associated with the galaxy cluster Abell 2744. Previous observations of this cluster were unable to resolve and remove coincidental X-ray point sources. After subtracting these, we find hot gas structures that are coherent over scales of 8 megaparsecs. The filaments coincide with over-densities of galaxies and dark matter, with 5-10 per cent of their mass in baryonic gas. This gas has been heated up by the cluster's gravitational pull and is now feeding its core. Our findings strengthen evidence for a picture of the Universe in which a large fraction of the missing baryons reside in the filaments of the cosmic web.

  1. How many cents on the dollar? Women and men in product markets.

    Gender inequality in contemporary U.S. society is a well-documented, widespread phenomenon. However, little is known about gender disparities in product markets. This study is the first to use actual market data to study the behavior of women and men as sellers and buyers and differences in market outcomes. We analyze a unique and large data set containing all eBay auction transactions of most popular products by private sellers between the years 2009 and 2012. Women sellers received a smaller number of bids and lower final prices than did equally qualified men sellers of the exact same product. On average, women sellers received about 80 cents for every dollar a man received when selling the identical new product and 97 cents when selling the same used product. These findings held even after controlling for the sentiments that appear in the text of the sellers' listings. Nonetheless, it is worth noting that this gap varied by the type of the product being sold. As a policy, eBay does not reveal the gender of users. We attribute the price differences to the ability of buyers to discern the gender of the seller. We present results from an experiment that shows that people accurately identify the gender of sellers on the basis of typical information provided in postings. We supplement the analysis with an additional off-eBay experiment showing that, in a controlled setting, people are willing to pay less for money-value gift cards when they are sold by women rather than men.

    Croplands in temperate regions are an important component of the carbon balance and can act as a sink or a source of carbon, depending on pedoclimatic conditions and management practices. Therefore the evaluation of carbon fluxes in croplands by modelling approach is relevant in the context of global change. This study was part of the Comete-Global project funded by the multi-Partner call FACCE JPI. Carbon fluxes, net ecosystem exchange (NEE), leaf area index (LAI), biomass, and grain production were simulated at the site level in three French crop experiments from the CarboEurope project. Several crops were studied, like winter wheat, rapeseed, barley, maize, and sunflower. Daily NEE was measured with eddy covariance and could be partitioned between gross primary production (GPP) and total ecosystem respiration (TER). Measurements were compared to DayCent simulations, a process-based model predicting plant production and soil organic matter turnover at daily time step. We compared two versions of the model: the original one with a simplified plant module and a newer version that simulates LAI. Input data for modelling were soil properties, climate, and management practices. Simulations of grain yields and biomass production were acceptable when using optimized crop parameters. Simulation of NEE was also acceptable. GPP predictions were improved with the newer version of the model, eliminating temporal shifts that could be observed with the original model. TER was underestimated by the model. Predicted NEE was more sensitive to soil tillage and nitrogen applications than measured NEE. DayCent was therefore a relevant tool to predict carbon fluxes in French crops at the site level. The introduction of LAI in the model improved its performance.

  3. Shampooing the reservoir : organic surfactant could increase Suffield oil recovery by 10 per cent

    EnCana is testing a new tertiary recovery technology in the Suffield area of southeastern Alberta which is known primarily for shallow natural gas. EnCana Corporation has approximately 1 billion barrels of original heavy oil in place in the Suffield area. Oil densities range from about 10 to 18 degrees API gravity. Viscosities range from 100 to 10,000 centipoise. Drilling began about 30 years ago. The primary productive formation is consolidated Mannville Glauconite sandstone which produces very little sand with the oil. About 15 per cent of the oil in place has been produced by primary production and waterfloods. In 2007, EnCana began testing an alkaline surfactant polymer flood operation in the Suffield heavy oil field that consists of 2 injector wells and 5 producers. Tests will continue until 2011. The surfactant acts as a detergent and reduces the interfacial tension between water and oil, thus mobilizing residual oil and increasing the displacement efficiency. In addition to the physical sweeping of a straight polymer flood, a surfactant polymer also washes oil from the rock. EnCana buys an alkaline chemical that is less expensive than surfactant. The alkaline injectant reacts with the organic acids in the oil to create a natural surfactant. EnCana was granted experimental scheme status by the Alberta Energy Resources Conservation Board. Instead of using fresh water, the pilot mixes its chemicals with saline water from a deep formation. EnCana will consider the pilot a commercial success if it recovers at least 10 per cent of the original oil in place. Thus far, the pilot is meeting that threshold. 1 fig.

    After having outlined challenges faced by cities and local communities regarding energy transition and the development of renewable energies, and recalled that 700 mayors have signed a commitment in Paris to reach 100 per cent of renewable energies by 2050, this report presents five recommended approaches: to integrate this objective of 100 per cent of renewable energies into wider challenges, to implement cooperation with surrounding rural territories, to highlight successes with actual projects, to invent new modes of commitment of actors within a territory, and to gather human resources for success. These main approaches are lessons learned from the analysis of five remarkable local policies which are then presented: Barcelona (towards self-sufficiency by 2050), Frankfurt (a German pioneer with a 100 per cent renewable road map), Frederikshavn (the objective of a new electricity system), Geneva (on the way to 100 per cent renewable for public buildings), and Malmoe (an industrial capital which became a renewable capital). The report then proposes five sheets with examples of achievements and projects in France which illustrate ways toward 100 per cent of renewable energies through different themes: prospective, urban-rural relationship, financing and investment, participation of local actors, and smart cities

    DayCent is a biogeochemical model of intermediate complexity widely used to simulate greenhouse gases (GHG), soil organic carbon and nutrients in crop, grassland, forest and savannah ecosystems. Although this model has been applied to a wide range of ecosystems, it is still typically parameterized through a traditional “trial and error” approach and has not been calibrated using statistical inverse modelling (i.e. algorithmic parameter estimation). The aim of this study is to establish and demonstrate a procedure for calibration of DayCent to improve estimation of GHG emissions. We coupled DayCent with the parameter estimation (PEST) software for inverse modelling. The PEST software can be used for calibration through regularized inversion as well as model sensitivity and uncertainty analysis. The DayCent model was analysed and calibrated using N2O flux data collected over 2 years at the Iowa State University Agronomy and Agricultural Engineering Research Farms, Boone, IA. Crop year 2003 data were used for model calibration and 2004 data were used for validation. The optimization of DayCent model parameters using PEST significantly reduced model residuals relative to the default DayCent parameter values. Parameter estimation improved the model performance by reducing the sum of weighted squared residual difference between measured and modelled outputs by up to 67 %. For the calibration period, simulation with the default model parameter values underestimated mean daily N2O flux by 98 %. After parameter estimation, the model underestimated the mean daily fluxes by 35 %. During the validation period, the calibrated model reduced sum of weighted squared residuals by 20 % relative to the default simulation. Sensitivity analysis performed provides important insights into the model structure providing guidance for model improvement.

  6. Reexamining Two Mythological Ballads from Christine de Pizan’s Cent Balades

    Directory of Open Access Journals (Sweden)

    Liudmila V. Evdokimova

    2018-03-01

    Full Text Available The article analyzes two mythological ballads from Christine de Pizan’s early collection Cent Balades (1399–1411. I propose to interpret them against allegorical commentary on Ovid’s Metamorphoses, a poem Ovide moralise and two treatises — Pierre Bersuire’s Ovididius moralizatus and Boccaccio’s De genealogia deorum gentilium. These works help us understand the ballad XC that critics have traditionally considered mysterious. The ballad tells the story of Adonis and his early death. Christine was familiar with the commentary on Metamorphoses that rendered the poem allegorically. The ballad can be therefore read as a story of the struggle for the human soul where Adonis emblematizes youth, Vulcan — desire, Pallas — wisdom, Juno — will, Jupiter — Supreme Reason, and Mercury — eloquence. Adonis must overcome corporeal passion voluntarily — this is the moral lesson that Christine gives in the allegorical form to her reader. Her relation of human will to reason is similar to that of Thomas Aquinas. The poem Ovide moralisé and Bersuire’s Ovididius moralizatus shed light on the allegorical subtext of the ballad LXI that narrates the love story of Io and Jupiter. Io epitomizes a sinful human soul temporarily deprived of humanity that, however, returns to the beloved — Jupiter, or God. The analysed poems demonstrate Christine’s taste for allegorical and obscure poetry that Boccaccio defended in his De genealogia deorum gentilium.

  7. Phase Transformations in a Uranium-Zirconium Alloy containing 2 weight per cent Zirconium

    1961-04-15

    The phase transformations in a uranium-zirconium alloy containing 2 weight percent zirconium have been examined metallographically after heat treatments involving isothermal transformation of y and cooling from the -y-range at different rates. Transformations on heating and cooling have also been studied in uranium-zirconium alloys with 0.5, 2 and 5 weight per cent zirconium by means of differential thermal analysis. The results are compatible with the phase diagram given by Howlett and Knapton. On quenching from the {gamma}-range the {gamma} phase transforms martensitically to supersaturated a the M{sub S} temperature being about 490 C. During isothermal transformation of {gamma} in the temperature range 735 to 700 C {beta}-phase is precipitated as Widmanstaetten plates and the equilibrium structure consists of {beta} and {gamma}{sub 1}. Below 700 C {gamma} transforms completely to Widmanstaetten plates which consist of {beta} above 660 C and of a at lower temperatures. Secondary phases, {gamma}{sub 2} above 610 C and {delta} below this temperature, are precipitated from the initially supersaturated Widmanstaetten plates during the isothermal treatments. At and slightly below 700 C the cooperative growth of |3 and {gamma}{sub 2} is observed. The results of isothermal transformation are summarized in a TTTdiagram.

    The ability of biogeochemical ecosystem models to represent agro-ecosystems depends on their correct integration with field observations. We report simultaneous calibration of 67 DayCent model parameters using multiple observation types through inverse modeling using the PEST parameter estimation software. Parameter estimation reduced the total sum of weighted squared residuals by 56% and improved model fit to crop productivity, soil carbon, volumetric soil water content, soil temperature, N2O, and soil3NO− compared to the default simulation. Inverse modeling substantially reduced predictive model error relative to the default model for all model predictions, except for soil 3NO− and 4NH+. Post-processing analyses provided insights into parameter–observation relationships based on parameter correlations, sensitivity and identifiability. Inverse modeling tools are shown to be a powerful way to systematize and accelerate the process of biogeochemical model interrogation, improving our understanding of model function and the underlying ecosystem biogeochemical processes that they represent.

    In a recent study which has not been published but could have been read by the authors, the ADEME tries to establish that, in 2050, it will be possible, in the sector of electricity production, to do without fossil and nuclear energies, and indicates that such a solution based on 100 per cent of renewable energies is economically viable. In this paper, the authors show that the renewable costs indicated by the ADEME in its '100 per cent renewable' scenario are significantly underestimated. They more precisely discuss the costs of roof-mounted or ground-based photovoltaic energy, ground-based and offshore wind energy, and of energy storage. They discuss issues related to grids, to intermittency management which they consider as an underestimated issue (constraints, imports, electric consumption, storage issues are addressed). The text of the ADEME study is also provided. This study aims at identifying the constraints under which it is possible to provide a 100 per cent renewable electricity, at determining the optimal energy mixes associated with different predictions of technological evolutions, consumption, and so on, at identifying the geographical distribution of the different renewable production means, and at determining the economic impacts of a 100 per cent renewable mix

    Full Text Available Abstract Background A 50 cent prescription levy was introduced in 2010 on the General Medical Services (GMS scheme (Irish public health insurance. This study sought to examine patient attitudes and opinions surrounding the 50 cent copayment. Given the small momentary value of the prescription fee, these results are of interest to policymakers internationally who wish to reduce copayments rather than abolish them. Methods A qualitative research design was used; semi structured interviews were carried out. Twenty four GMS eligible participants were interviewed in 23 interviews. Fifteen females and 9 males took part. Ages varied from 31- >70 years. Patients were invited to be interviewed in both independent and chain community pharmacies in three types of setting; 1 a socially deprived urban area, 2 a suburban affluent area and 3 a rural area. The Framework method was used for data management and analysis using QSR International’s NVivo 9.2 qualitative data analysis software. The “Francis method” was used to test for data saturation. Results Results are of interest to the Irish context and also at a broader international level. Patients were mostly accepting of the prescription levy with some reservations concerning an increased price and the way in which generated revenue would be used by government. Participants identified waste of prescription drugs at the hand of patients (moral hazard, but there was discordant opinion on whether the 50 cent copayment would halt this moral hazard. Interviewees felt the levy was affordable, albeit some may suffer a financial impact more than others. Conclusions This qualitative study gives important insights into the experiences of GMS patients with regard to the prescription levy. Information regarding the appropriateness of a 50 cent copayment as a symbolic copayment needs to be confirmed by quantitative analysis. Further insight is required from a younger population.

    Paris, May 14 2007 - For the first quarter 2007, Gaz de France Group posted euro 9,053 million in consolidated sales. This 11 per cent decrease on the same period in 2006 is a direct result of the extremely warm weather conditions in France and Europe this winter. In contrast, under average climate conditions sales improved by 1.3 per cent. In France, where the winter of 2006/2007 was the warmest in fifty years, sales were impacted by 18 billion kWh in the quarter compared to a quarter with average-climate conditions and 32 billion kWh compared to the first quarter 2006 which, in contrast, was colder than normal. The impact of the weather had similar effects on sales outside France. The highly unusual weather conditions also had an indirect impact on the market and, consequently, on both gas production and the arbitrage activities. Not withstanding these effects, the Group continued to consolidate its position in foreign markets, with sales outside France reaching euro 3,341 million. The share of sales outside France increased by 3 points in the first quarter of 2007 versus first quarter 2006 to 37 per cent as at end March 2007. The group reiterates the 2007 financial objective as presented at the full year 2006 results: '2007 will be a year of consolidation and the EBITDA should be in line with that of 2006'.

    The article analyzes the scientific discussion about the existence of a domestic space reserved to women in Etruscan and Roman houses. The hypotesis regarding the existence of a 'gynaeceum' has been recently proposed for the Etruscan houses built on Palatino in Rome (VI cent. B.C.) and for the ancient phase of the Centaurus Protodomus in Pompei. Considering the specific role of Roman matronae as laniferae, and also a substantial equality of social role between Etruscan men and women, it is possible to advance the hypotesis of the existence of a room originally reserved to women (oecus) on one side of the tablinum, the symmetrical room being reserved to men (triclinium).

    The aim was to evaluate the effect of diquafosol on tear film parameters and corneal aberrations after cataract surgery. This retrospective, comparative, observational case series included patients who underwent cataract surgery with or without peri-operative use of diquafosol three per cent ophthalmic solution. Patients in group I (31 eyes) were treated with diquafosol three per cent ophthalmic solution six times a day from one week before surgery to three months after surgery. Patients in group II (33 eyes) underwent cataract surgery without being administered diquafosol. Tear film break-up time (BUT), the ocular surface disease index (OSDI), the Oxford Scheme score, Schirmer's test I and corneal aberrations were determined before and at one and three months post-surgery. In group I, the BUT, OSDI and Oxford Scheme score showed significant improvement at one and three months post-surgery (p = 0.002 for BUT at one month and three months, p = 0.023 and p = 0.049 for OSDI at one month and three months and p = 0.001 and p = 0.026 for Oxford Scheme at one month and three months), compared to baseline. In group II, the BUT, OSDI and Oxford Scheme score did not show any significant improvement during the follow-up period. In both groups, Schirmer's test I significantly decreased at three months post-surgery (p = 0.011 for group I and p = 0.034 for group II), compared to baseline. There were significant differences in the BUT and OSDI between the groups at three months post-surgery (p = 0.037 for BUT and p = 0.011 for OSDI). Regarding the corneal aberration, there were no significant differences between the groups at three months post-surgery. Peri-operative application of diquafosol three per cent ophthalmic solution may prevent dry eye-related ocular surface changes accompanied by improvement of ocular symptom. No definite changes in corneal aberrations were noted. © 2017 Optometry Australia.

    Atmospheric deposition of nitrogen (N) and sulfur (S) cause complex responses in ecosystems, from fertilization to forest ecosystem decline, freshwater eutrophication to acidification, loss of soil base cations, and alterations of disturbance regimes. DayCent-Chem, an ecosystem simulation model that combines ecosystem nutrient cycling and plant dynamics with aqueous geochemical equilibrium calculations, was developed to address ecosystem responses to combined atmospheric N and S deposition. It is unique among geochemically-based models in its dynamic biological cycling of N and its daily timestep for investigating ecosystem and surface water chemical response to episodic events. The model was applied to eight mountainous watersheds in the United States. The sites represent a gradient of N deposition across locales, from relatively pristine to N-saturated, and a variety of ecosystem types and climates. Overall, the model performed best in predicting stream chemistry for snowmelt-dominated sites. It was more difficult to predict daily stream chemistry for watersheds with deep soils, high amounts of atmospheric deposition, and a large degree of spatial heterogeneity. DayCent-Chem did well in representing plant and soil carbon and nitrogen pools and fluxes. Modeled stream nitrate (NO3-) and ammonium (NH4+) concentrations compared well with measurements at all sites, with few exceptions. Simulated daily stream sulfate (SO42-) concentrations compared well to measured values for sites where SO42- deposition has been low and where SO42- adsorption/desorption reactions did not seem to be important. The concentrations of base cations and silica in streams are highly dependent on the geochemistry and weathering rates of minerals in each catchment, yet these were rarely, if ever, known. Thus, DayCent-Chem could not accurately predict weathering products for some catchments. Additionally, few data were available for exchangeable soil cations or the magnitude of base cation

  1. Stress corrosion cracking of an uranium-6 weight per cent niobium in gaseous oxygen, nitrogen and hydrogen

    Stress corrosion cracking (SCC) of uranium-6 weight per cent niobium alloy is studied in gaseous oxygen at room temperature (for pressures between 4.10 -7 and 0.15MPa) and 100 0 C (pressure of 0.15 MPa) and in gaseous hydrogen (for pressures between 10 -6 and 0.15 MPa). SCC map and cracking kinetics are determined as fonctions of stress-intensity factor, pressure and temperature. For oxygen, temperature seems to have no effect on the alloy embrittlement within the range of this study but the pressure influence is more complex. At room temperature, hydrogen pressure less than 0.15 MPa has no influence on the cracking kinetics. For a pressure of 0.15 MPa, fracture occurs by hydriding reaction. Complementary analyses on fracture surfaces lead to propose different mechanics responsible for cracking kinetics in these environments [fr

    In order to study the transformation kinetics of U-Zr alloys with a Zr content of 6 per cent in weight, the authors searched for a slow enough electrolytic polishing bath, and for an attack and examination method to highlight martensite structures produced by austempering and water tempering, and ultra-fine decomposition structures obtained by austempering. The authors explain the choice of a perchloric-butyl glycol polishing bath, of an examination under polarized light or normal light after appropriate attacks. These studies are reported for annealed alloys, and for processed alloys with martensite or ultra-fine decomposition structures [French] L'etude de la cinetique de transformation des alliages U-Zr a 6 pc en poids de Zr a necessite la recherche d'un bain de polissage electrolytique assez lent et de methodes d'attaque et d'examen qui permettent la mise en evidence des structures martensitiques (provenant de trempes etagees ou de trempes a l'eau) et des structures de decomposition ultrafines (obtenues par trempes etagees). Nous nous sommes arretes dans notre choix: - sur un bain de polissage perchlorique-butyl glycol; sur des examens en lumiere polarisee ou en lumiere normale apres attaques appropriees (en cellule dans le meme electrolyte ou au tampon dans un bain phosphorique ethylene glycol).

    The Eu is considering the adoption of a tighter emission target, to replace the agreed -20 per cent emission target already agreed on. In this study, we analyze the implications of the proposed -30 per cent EU-wide emission cut from the perspective of the Finnish economy. We use an energy system model to study the technological choices and direct energy and investment costs of the stricter target, and an applied general equilibrium model to analyse its economic implications at industry and macroeconomic levels. We find that the stricter target increases the economic costs roughly proportionally to the abatement effort and consist mostly of the welfare losses of taxation. (orig.)

    The United Kingdom currently reports nitrous oxide emissions from agriculture using the IPCC default Tier 1 methodology. However Tier 1 estimates have a large degree of uncertainty as they do not account for spatial variations in emissions. Therefore biogeochemical models such as DailyDayCent (DDC) are increasingly being used to provide a spatially disaggregated assessment of annual emissions. Prior to use, an assessment of the ability of the model to predict annual emissions should be undertaken, coupled with an analysis of how model inputs influence model outputs, and whether the modelled estimates are more robust that those derived from the Tier 1 methodology. The aims of the study were (a) to evaluate if the DailyDayCent model can accurately estimate annual N 2 O emissions across nine different experimental sites, (b) to examine its sensitivity to different soil and climate inputs across a number of experimental sites and (c) to examine the influence of uncertainty in the measured inputs on modelled N 2 O emissions. DailyDayCent performed well across the range of cropland and grassland sites, particularly for fertilized fields indicating that it is robust for UK conditions. The sensitivity of the model varied across the sites and also between fertilizer/manure treatments. Overall our results showed that there was a stronger correlation between the sensitivity of N 2 O emissions to changes in soil pH and clay content than the remaining input parameters used in this study. The lower the initial site values for soil pH and clay content, the more sensitive DDC was to changes from their initial value. When we compared modelled estimates with Tier 1 estimates for each site, we found that DailyDayCent provided a more accurate representation of the rate of annual emissions. (paper)

    Campania has always offered suitable climatic and physiographic conditions for human settlements since prehistoric times. In particular, many Graeco-Roman towns developed along its coasts starting from the 7th-6th cent. BC. In the last decade, geoarchaelogical surveys have been carried out in the archaeological excavations of Neapolis, Paestum and Elea-Velia allowing the main steps of the landscape evolution around these towns to be defined in detail. The greek town of Neapolis rose in the late 6th cent. BC [1] on a terrace overlooking a low-relief rocky coast surrounded by volcanic hills. Port activities developed in a protected bay facing the town from the 4th-2nd cent. BC up to the 4th cent. AD, as testified by the discovery of structures and shipwrecks [2, 3, 4]. Starting from the 3rd cent. AD a spit bar formed at the bay entrance causing the progressive establishment of a lagoon which was gradually filled up by alluvial inputs and completely closed in the 5th cent. AD. During the same period, episodes of increased alluvial inputs were also recorded further west along the coast, where a narrow sandy beach formed at the cliff toe. The greek town of Poseidonia, renamed Paestum by the Romans, was founded in the 540 BC on a travertine terrace facing the sandy littoral of a prograding coastal plain [5]. In front of the main town door, a coastal lagoon developed thanks to the growth of a dune ridge and was probably used for harbor activities [5]. After this period the shoreline shifted seawards, another dune ridge formed and the back-ridge depression was filled with fluvial-marshy deposits, slowly drying up. Phases of travertine deposition, which characterized the SE sector of the plain all along the Holocene, were recorded in the northern and southern quarters of the town in historical times and were connected to the abandonment of the town in the early Medieval times. The greek colony of Elea-Velia was located on top of a siliciclastic promontory where the ruins of

    Atmospheric deposition of sulfur and nitrogen species have the potential to acidify terrestrial and aquatic ecosystems, but nitrate and ammonium are also critical nutrients for plant and microbial productivity. Both the ecological response and the hydrochemical response to atmospheric deposition are of interest to regulatory and land management agencies. We developed a non-spatial biogeochemical model to simulate soil and surface water chemistry by linking the daily version of the CENTURY ecosystem model (DayCent) with a low temperature aqueous geochemical model, PHREEQC. The coupled model, DayCent-Chem, simulates the daily dynamics of plant production, soil organic matter, cation exchange, mineral weathering, elution, stream discharge, and solute concentrations in soil water and stream flow. By aerially weighting the contributions of separate bedrock/talus and tundra simulations, the model was able to replicate the measured seasonal and annual stream chemistry for most solutes for Andrews Creek in Loch Vale watershed, Rocky Mountain National Park. Simulated soil chemistry, net primary production, live biomass, and soil organic matter for forest and tundra matched well with measurements. This model is appropriate for accurately describing ecosystem and surface water chemical response to atmospheric deposition and climate change. ?? 2006 Elsevier B.V. All rights reserved.

    The DailyDayCent biogeochemical model was used to simulate nitrous oxide (N 2 O) emissions from two contrasting agro-ecosystems viz. a mown-grassland and a grain-cropping system in France. Model performance was tested using high frequency measurements over three years; additionally a local sensitivity analysis was performed. Annual N 2 O emissions of 1.97 and 1.24kgNha -1 year -1 were simulated from mown-grassland and grain-cropland, respectively. Measured and simulated water filled pore space (r=0.86, ME=-2.5%) and soil temperature (r=0.96, ME=-0.63°C) at 10cm soil depth matched well in mown-grassland. The model predicted cumulative hay and crop production effectively. The model simulated soil mineral nitrogen (N) concentrations, particularly ammonium (NH 4 + ), reasonably, but the model significantly underestimated soil nitrate (NO 3 - ) concentration under both systems. In general, the model effectively simulated the dynamics and the magnitude of daily N 2 O flux over the whole experimental period in grain-cropland (r=0.16, ME=-0.81gNha -1 day -1 ), with reasonable agreement between measured and modelled N 2 O fluxes for the mown-grassland (r=0.63, ME=-0.65gNha -1 day -1 ). Our results indicate that DailyDayCent has potential for use as a tool for predicting overall N 2 O emissions in the study region. However, in-depth analysis shows some systematic discrepancies between measured and simulated N 2 O fluxes on a daily basis. The current exercise suggests that the DailyDayCent may need improvement, particularly the sub-module responsible for N transformations, for better simulating soil mineral N, especially soil NO 3 - concentration, and N 2 O flux on a daily basis. The sensitivity analysis shows that many factors such as climate change, N-fertilizer use, input uncertainty and parameter value could influence the simulation of N 2 O emissions. Sensitivity estimation also helped to identify critical parameters, which need careful estimation or site

    We report the detection of the Lyman continuum (LyC) radiation of the compact star-forming galaxy (SFG) J1154+2443 observed with the Cosmic Origins Spectrograph (COS) onboard the Hubble Space Telescope. This galaxy, at a redshift of z = 0.3690, is characterized by a high emission-line flux ratio O32 = [O III] λ5007/[O II] λ3727 = 11.5. The escape fraction of the LyC radiation fesc(LyC) in this galaxy is 46 per cent, the highest value found so far in low-redshift SFGs and one of the highest values found in galaxies at any redshift. The narrow double-peaked Ly α emission line is detected in the spectrum of J1154+2443 with a separation between the peaks Vsep of 199 km s-1, one of the lowest known for Ly α-emitting galaxies, implying a high fesc(Ly α). Comparing the extinction-corrected Ly α/H β flux ratio with the case B value, we find fesc(Ly α) = 98 per cent. Our observations, combined with previous detections in the literature, reveal an increase of O32 with increasing fesc(LyC). We also find a tight anticorrelation between fesc(LyC) and Vsep. The surface brightness profile derived from the COS acquisition image reveals a bright star-forming region in the centre and an exponential disc in the outskirts with a disc scale length α = 1.09 kpc. J1154+2443, compared to other known low-redshift LyC leakers, is characterized by the lowest metallicity, 12+log O/H = 7.65 ± 0.01, the lowest stellar mass M⋆ = 108.20 M⊙, a similar star formation rate SFR = 18.9 M⊙ yr-1, and a high specific SFR of 1.2 × 10-7 yr-1.

  12. Improving radiation data quality of USDA UV-B monitoring and research program and evaluating UV decomposition in DayCent and its ecological impacts

    Chen, Maosi

    Solar radiation impacts many aspects of the Earth's atmosphere and biosphere. The total solar radiation impacts the atmospheric temperature profile and the Earth's surface radiative energy budget. The solar visible (VIS) radiation is the energy source of photosynthesis. The solar ultraviolet (UV) radiation impacts plant's physiology, microbial activities, and human and animal health. Recent studies found that solar UV significantly shifts the mass loss and nitrogen patterns of plant litter decomposition in semi-arid and arid ecosystems. The potential mechanisms include the production of labile materials from direct and indirect photolysis of complex organic matters, the facilitation of microbial decomposition with more labile materials, and the UV inhibition of microbes' population. However, the mechanisms behind UV decomposition and its ecological impacts are still uncertain. Accurate and reliable ground solar radiation measurements help us better retrieve the atmosphere composition, validate satellite radiation products, and simulate ecosystem processes. Incorporating the UV decomposition into the DayCent biogeochemical model helps to better understand long-term ecological impacts. Improving the accuracy of UV irradiance data is the goal of the first part of this research and examining the importance of UV radiation in the biogeochemical model DayCent is the goal of the second part of the work. Thus, although the dissertation is separated into two parts, accurate UV irradiance measurement links them in what follows. In part one of this work the accuracy and reliability of the current operational calibration method for the (UV-) Multi-Filter Rotating Shadowband Radiometer (MFRSR), which is used by the U.S. Department of Agriculture UV-B Monitoring and Research Program (UVMRP), is improved. The UVMRP has monitored solar radiation in the 14 narrowband UV and VIS spectral channels at 37 sites across U.S. since 1992. The improvements in the quality of the data result

  2. An innovative and very promising use of tidal turbines. Tidal turbines can produce twenty per cent of the French electricity. An economic solution can produce 500 GW of tide energy. An innovative use of tidal turbines can produce 10 per cent of the World energy

    2013-01-01

    A set of articles outlines and describes the opportunities of energy production associated with the use of tidal turbines. Such a technological principle is very efficient in terms of costs but very few natural sea or river sites present favourable conditions, notably in terms of current speed. A first article addresses the peculiarities of sea tide energy, presents the different concepts and components of a sea tide power plant (tanks or basins, plants), describes the present use of tidal turbines, proposes a new solution (the 'Marelienne'), describes and assesses the integration into the grid and the energy storage, evokes the production gain obtained by pumping and the association with wind turbines, describes the construction mode, discusses the various impacts (visual impact, impacts on the environment, direct and indirect socio-economic impacts), discusses issues related to navigation, presents an example of production, costs and impacts (case of the Bay of Somme), evokes other potential areas in France (about the Chausey island and about the Re island), discusses the world potential, evokes other examples in Europe, in Asia, in America, Africa and Australia), indicates the global cost for the main sites, outlines technical and economic uncertainties. The same aspects and issues can be found in the other articles which outline that tidal turbines can produce twenty per cent of the French electricity, that an economic solution can produce 500 GW of tide energy, and that an innovative use of tidal turbines can produce 10 per cent of the World energy

    Full Text Available La région de Mendoza est particulièrement vulnérable au réchauffement climatique. Les glaciers du massif de l’Aconcagua ont amorcé un important retrait depuis la fin du Petit Âge de Glace. Or la disparition de ces glaciers risque d’entraîner une modification des régimes hydrologiques qui, jusqu’à présent, se caractérisaient par de hautes eaux estivales. Ce pic estival pourrait à l’avenir être atténué et remettre en cause les stratégies de gestion de la ressource en eau. Nous faisons ici le point sur les variations récentes de l’englacement et tentons de dessiner un scénario prospectif.Mendoza area is highly vulnerable to the global warming. The glaciers of the Aconcagua massif are currently shrinking, this trend of retreat began at the end of the Little Ice Age. The disappearance of glaciers may modify hydrological regimes. The discharge is currently at maximum during summer (related to glacier melt, but the peak discharge may occur during spring (related to snow melt in the next future. In this paper we synthesize the recent variations of the glaciers and propose a pattern of future variations.

  4. Aspects récents de la thermodynamique des solutions de polymères Recent Aspects of the Thermodynamics of Polymer Solutions

    Dayantis J.

    2006-11-01

    Full Text Available On examine dans cet article différentes approches de la thermodynamique des solutions de polymères placées dans leur contexte historique. On rappelle d'abord le modèle du réseau de Flory-Huggins et on en souligne les déficiences. On traite ensuite brièvement de la mécanique statistique des solutions de polymères introduite par Prigogine en 1957 et on montre qu'elle constitue un progrès qualitatif par rapport à la théorie du réseau, mais qu'elle ne prévoit cependant pas de manière quantitative les propriétés de ces solutions. On montre ensuite que le concept de volume libre, qui permet un traitement simplifié de certaines quantités, permet également d'expliquer tout naturellement l'existence d'une deuxième température de séparation en phase lorsque l'on élève la température, propriété qui différencie les solutions de polymères des mélanges de liquidés simples. Enfin, dans une dernière partie, on mentionne brièvement les travaux récents de l'École de Paris, qui traite les solutions de polymères par analogie avec les transitions magnétiques. This article examines différent approaches ta the thermodynamics of polymer solutions set in their historical context. First of all, the Flory-Huggins network model is described and ifs deficiencies are pointed out. Then attention is briefly drawn to the statistical mechanics of polymer solutions as introduced by Prigogine in 1957, and this mechanics is shown to be a qualitative advance compared with the network theory, but it nonetheless does not quantitatively predict the properties of such solutions. It is then shown that the concept of free volume, enabling some quantifies to be treated in a simplified way, also serves to provide a quite natural explanation for the existence of a second phase separation temperature when the temperature is raised, i. e. a property that differentiates polymer solutions from simple liquid mixtures. In the final part, brief mention is made

  5. Evaluation and adjustment of description of denitrification in the DailyDayCent and COUP models based on N2 and N2O laboratory incubation system measurements

    data-sets are needed in view of the extreme spatio-temporal heterogeneity of denitrification. DASIM will provide such data based on laboratory incubations including measurement of N2O and N2 fluxes and determination of the relevant drivers. Here, we present how we will use these data to evaluate common biogeochemical process models (DailyDayCent, Coup) with respect to modeled NO, N2O and N2 fluxes from denitrification. The models are used with different settings. The first approximation is the basic "factory" setting of the models. The next step would show the precision in the results of the modeling after adjusting the appropriate parameters from the result of the measurement values and the "factory" results. The better adjustment and the well-controlled input and output measured parameters could provide a better understanding of the probable scantiness of the tested models which will be a basis for future model improvement.

  2. Attenuated Total Reflection Fourier Transform Infrared (ATR FT-IR) Spectroscopy as a Forensic Method to Determine the Composition of Inks Used to Print the United States One-cent Blue Benjamin Franklin Postage Stamps of the 19th Century.

    Science.gov (United States)

    Brittain, Harry G

    2016-01-01

    Through the combined use of infrared (IR) absorption spectroscopy and attenuated total reflectance (ATR) sampling, the composition of inks used to print the many different types of one-cent Benjamin Franklin stamps of the 19th century has been established. This information permits a historical evaluation of the formulations used at various times, and also facilitates the differentiation of the various stamps from each other. In two instances, the ink composition permits the unambiguous identification of stamps whose appearance is identical, and which (until now) have only been differentiated through estimates of the degree of hardness or softness of the stamp paper, or through the presence or absence of a watermark in the paper. In these instances, the use of ATR Fourier transform infrared spectroscopy (FT-IR) spectroscopy effectively renders irrelevant two 100-year-old practices of stamp identification. Furthermore, since the use of ATR sampling makes it possible to obtain the spectrum of a stamp still attached to its cover, it is no longer necessary to identify these blue Franklin stamps using their cancellation dates. © The Author(s) 2015.

  3. Reduction of misclassification rates of obesity by body mass index using dual-energy X-ray absorptiometry scans to improve subsequent prediction of per cent fat mass in a Caucasian population

    DEFF Research Database (Denmark)

    Pedersen, Susie Dawn; Astrup, Arne; Skovgaard, Ib

    2011-01-01

    Recognition is increasing for the errors of body mass index (BMI) in classification of excess body fat. Dual-energy X-ray absorptiometry (DXA) is accurate to assess body fat mass per cent (%FM), but is underutilized clinically. We examined the prevalence of obesity misclassification by BMI....... The majority of men with BMI 25–27 kg m-2 and women with BMI 24–26 kg m-2 were misclassified. Using multiple scan data (189 men, 311 women) and calculating the patient-specific constant C = (1 - %FM/100)3/2 ¥ BMI from baseline BMI and %FM, misclassification rates were halved for both genders when a personal...... threshold, BMIT, was used ([BMIT = C/(0.75)3/2] for men and [BMIT = C/(0.65)3/2] for women). We conclude that simple formulae allow evaluation of fatness of individual patients more accurately than BMI, with the use of one baseline DXA scan, and enable the establishment of patient-specific obesity treatment...

  13. Energy and Exergy Balances for Modern Diesel and Gasoline Engines Bilans d’énergie et d’exergie pour des moteurs Diesel et essence récents

    Directory of Open Access Journals (Sweden)

    Bourhis G.

    2009-11-01

    Full Text Available The aim is here to evaluate the difference between the energy and exergy (or available energy balances when heat recovery is considered in an internal combustion engine. In the first case, the entropy of the system is not taken into account so that, the maximum useful work recoverable from a system can not be estimated. Then, the second case is much more adapted to estimate heat recovery potential. In this paper, two modern engines are evaluated. First, an up-to-date gasoline engine: three-cylinder, downsized, low friction, then a modern common rail downsized Diesel engine. For each one, two energy and exergy balances are given for two different part-load operating points representative of the NEDC cycle using experimental data from steady state engine test benches. For the Diesel engine, it is shown that effective work represents around 30% and that around 55% of the energy introduced into the combustion chamber is lost (in the form of heat, especially in exhaust gas, in water coolant and oil. But when considering exergy balance, only 12% of the total exergy introduced through the fuel can be recovered, in order to produce useful work. Expecting a 25% exergy recovery efficiency, the effective engine efficiency could be increased by 10%. For the gasoline engine, the increase of the output work could be around 15%. L’objectif est ici d’évaluer la différence entre bilan d’énergie et d’exergie (ou énergie utile pour des moteurs à combustion interne lorsque la problématique de récupération d’énergie est prise en compte. Dans le premier cas, l’entropie du système n’est pas considérée, si bien que le travail utile maximal qu’il est possible de récupérer d’un système ne peut pas être estimé. Tandis que le second cas est bien mieux adapté pour estimer le potentiel de la récupération d’énergie. Dans cet article, deux moteurs modernes sont étudiés. Le premier est un moteur essence récent, 3 cylindres, de cylindr

    Directory of Open Access Journals (Sweden)

    Fauveau M.

    2006-11-01

    Full Text Available La diminution de volume des cavités salines exploitées à Tersanne depuis quinze ans a conduit le Gaz de France à développer des études sur la rhéologie du sel en collaboration avec des laboratoires universitaires. Ces études ont abouti à la mise au point d'un modèle rhéologique rendant compte des observations effectuées in situ. Simultanément ont été développés, en collaboration avec l'École Nationale Supérieure des Mines de Paris, des modèles numériques qui permettent d'effectuer des simulations du comportement mécanique des cavités. Le plus performant de ces modèles est le code VIPLEF. Validé par une confrontation avec des solutions analytiques et la simulation d'un cas réel (cavité TE O2 de Tersanne, ce programme a permis d'étudier l'influence de la forme d'une cavité sur sa perte de volume et d'ébaucher un critère de choix de forme optimale . Les récentes études ont également permis de mettre en évidence les paramètres qui concourent à la remontée du fond des cavités (gravité, gradient géothermique, stratigraphie, forme de la cavité, etc. , grâce à l'utilisation de ce modèle. De nombreuses intuitions de physiciens ont pu être ainsi confirmées et approfondies par le calcul numérique. The reduction in the geometric volume of the salt cavities used for gas storage at Tersanne, France, for 15 years led Gaz de France to undertake research on the rheology of salt in cooperation with university laboratories. This research led to the development of a rheological model describing in situ observations. At the same time, in collaboration with the Ecole Nationale Supérieure des Mines in Paris, numerical models were developed for simulating the mechanical behavior of cavities. The most effective such model is the VIPLEF code. Checked by comparison with analytical solutions and by simulation of an actual case (TE O2 cavity at Tersanne, this program was used to study the influence of the shape of a cavity on

    Full Text Available Introduction : Cette analyse a comme objectif de rassembler les articles évalués par les pairs utilisant des données tirées de l'Étude canadienne sur l'incidence des signalements de cas de violence et de négligence envers les enfants (ECI publiées depuis novembre 2011 ainsi que des suréchantillons provinciaux de l'ECI, d'évaluer la qualité de leurs conclusions, de les synthétiser et de faire le bilan des variations dans l'utilisation de ces données. Méthodologie : Nous avons sélectionné les articles au moyen du suivi des demandes d'accès aux données de l'ECI effectué par l'Agence de la santé publique du Canada et au suivi des publications produites au moyen de ces données. Deux évaluateurs au moins ont examiné de façon indépendante les articles et en ont évalué la qualité. Résultats : Nous avons conservé 32 articles. Leurs points forts étaient en général les suivants : objectifs de recherche clairement établis, variables de contrôle appropriées, analyses pertinentes, taille de l'échantillon suffisante, conclusions pertinentes et utilité pour les pratiques et politiques. Leur point problématique était le plus souvent une définition floue des variables et des critères d'inclusion des cas. La plupart du temps, les articles mesuraient les associations entre les caractéristiques des mauvais traitements et celles des enfants, des pourvoyeurs de soins, du ménage et de l'organisme ou de la personne à l'origine du signalement et ils s'intéressaient aux conséquences des signalements, par exemple l'ouverture d'un dossier pour une prestation continue de services ou le placement. Conclusion : Les articles utilisant des données de l'ECI ont obtenu des scores positifs pour la plupart des indicateurs de qualité. Dans leurs analyses les plus récentes, les chercheurs se sont concentrés sur les catégories de maltraitance insuffisamment étudiées jusqu'ici (exposition à la violence conjugale, négligence et

    Full Text Available L’objectif de cet article est de dresser un portrait des usages numériques éducatifs des élèves allophones issus de l’immigration récente, notamment en lien avec leurs usages numériques non éducatifs et leur compétence numérique, en vue de soutenir leur intégration linguistique et scolaire. Deux cent trente-six élèves de classes d’accueil de l’île de Montréal ont participé à une expérimentation enregistrée sur ordinateur. Les résultats indiquent que les usages numériques éducatifs sont peu intégrés aux usages non éducatifs que développent les élèves en contexte extrascolaire, ce qui ne semble pas démarquer les élèves allophones issus de l’immigration récente des élèves occidentaux. The goal of this article is to provide an overview of the educational digital uses by allophone students from recent immigration, particularly in relation to their non-educational digital uses and their digital competence, in order to support their linguistic and academic integration. Two hundred thirty-six students from welcoming classes from the island of Montreal participated in an experiment recorded on computers. Results indicate that the educational digital uses are little integrated to non-educational uses developed by students in extracurricular settings, which does not seem to set allophone students from recent immigration apart from non-immigrant students.

    Experiments on plutonium and 90 pour cent enriched uranium solutions have been made in the Alecto reactor with a tank of external diameter 300 mm. Various geometries Lave been tested, for variable concentrations of fissionable salts. The critical mass was studied as a function of the concentration in various reflector conditions (water, concrete, wood) and the experimental values were compared with calculated values. The effects of cadmium as a reflector and of the stainless steel tank were also studied. Lastly were carried out measurements of {beta}/{tau}, ratio of the effective fraction of delayed neutrons to the average lifetime of the neutrons in the reactor. (authors) [French] Des experiences sur des solutions de plutonium et d'uranium enrichi a 90 pour cent ont ete effectuees dans le reacteur Alecto, avec une cuve de diametre exterieur 300 mm.

On a etudie la masse critique en fonction de la concentration, dans plusieurs conditions de reflexion (eau, beton, bois), et on a compare les resultats experimentaux aux valeurs donnees par le calcul.

  8. Strategies for Ontario gas marketers: making cents of it all

    Energy Technology Data Exchange (ETDEWEB)

    Walsh, P.R. [Energy Objective Ltd., London ON (Canada)

    2001-07-01

    The evolution of the natural gas supply, demand and pricing equilibrium is discussed. Prices for natural gas are a function of supply and demand. An analysis of supply and demand forecasting shows a consistent trend to mirror the actual outcome. In the case of price, the forecasts are less consistent and indicate the need for a different approach for choosing an appropriate strategy for price determination. Analysis of price data over the past 30 years indicate that increases in natural gas prices in North America have been strongly correlated with increase in economic growth. Increased economic growth creates an increase in energy demand and a related increase in energy prices. Conversely, decreased economic activity tends to coincide with energy price spikes and subsequent declines in energy prices. These results lead to the conclusion that a successful strategy for long term pricing requires the natural gas marketer to establish the point at which the current price is, relative to the long-term equilibrium between demand, supply and pricing. 12 figs.

  12. QUALITY OF FAMILY INTERACTIONS AND ADOLES- CENTS' PERSONALITY TRAITS

    Directory of Open Access Journals (Sweden)

    Tamara Efendić-Spahić

    2013-02-01

    Full Text Available Family as the basic social unit is the primary environment of the development of an individual. In the family setting an individual satisfies (or should satisfy the basic human needs such as the need for safety and love. In the studies of patterns of unadapted behavior of children and adolescents, temperament is most often stated as the key human characteristic feature that is the most important predictor in the development of unadapted and antisocial forms of behavior. The survey of dispositional empirically identified and inheritance-determined characteristics has been described in detail by Eysenck’s dimensional model of personality through mutually orthogonal and bipolar characteristics: Neuroticism, Extraversion and Psychoticism. The formation of these dispositional characteristics is closely related to parents’ sensitivity to child’s needs and the level of parents’ engagement in their parental role. Therefore, the aim of this research was to examine to what extent the assessment of the quality of the relationship with parents is an important predictor for explaining the basic dimensions of adolescents’ personalities. The research was conducted on an appropriate sample of 135 adolescents, students of the Faculty of Philosophy in Tuzla. The results confirm that the aspects of negative relationships with mother and father are important predictors for explaining dimensions of Neuroticism and Psychoticism, which are very significant correlations of unadapted and antisocial behavior. Also, the results indicate less significant importance of positive relations with mother and father for explaining dependent research variables since it is presumed that positive relations act more as a protective factor whereas the assessment of negative relationships with parents is certainly more important, especially for the dimensions related to bad adaptation of adolescents. The results also indicate equal importance of mother and father in the upbringing process for explaining the basic personality dimensions of adolescents since negative relationships with both mother and father appear as equally important predictors for explaining the dimensions of Neuroticism and Psychoticism in adolescents.

  4. A FEW SOUTH AFRICAN CENTS' WORTH ON BITCOIN

    Directory of Open Access Journals (Sweden)

    Annamart Nieman

    2015-12-01

    Full Text Available This article is aimed at augmenting current awareness of virtual currencies ("VCs" in the South African legal community. To this end, it introduces the reader to VCs in general and decentralised convertible VCs ("DCVCs" in particular. Due to their design and interaction with the real economy and currency, DCVCs are on the radar of many financial regulators worldwide. As Bitcoin is considered the leading type of DCVC in terms of value and volume, its early beginnings in South Africa are probed. Although regulation should follow innovation, awareness of the VC ecosystem will not only warrant appropriate regulatory intervention when the time comes, but will also enable the growth and development opportunities associated with VCs. South Africa has not promulgated any legislation pertaining to VCs. The potential applicability of all current legislation and regulations relevant to VCs calls for in-depth research. This article aspires to serve as an appetiser to do so.

    The author made a systematic study of the annealing of the beta phase retained by water-quenching in uranium-chromium alloys of concentrations between 0.37 and 4 of chromium percent. It is shown that alloys containing less than 1 atom per cent are transformed at temperatures between room temperature and 250 deg. C according to a bainitic process involving activation energies of the order of 14,500 cal/mole. Alloys containing more than 1 at. per cent are transformed at temperature between 400 and 650 deg. C by way of a germination and growth process involving an activation energy of the order of 33,000 cal/mole. The limit of solubility of chromium in beta uranium plays a fundamental part in the transformations of the alloys. The TTT curves of beta {yields} alpha transformation were drawn by the use of a thermo-dilatometer of very low inertia. The transformation law may be expressed 1 x = exp. (kt){sup n}; x represents the degree of progression of the transformation, k a coefficient dependent on the temperature, and n an exponent depending only on the composition of the alloy. A micrographic and crystallographic study confirmed the results found by dilatometry; in particular it was possible to measure the progression rates of the transformation.

    The objective of this study has been to assess to which extent solar photovoltaic energy will represent a significant part of world electric power consumption by 2050, while notably taking the economic dimension, resource availability and problems related to intermittency management into account. After a recall of the relative correlation between solar radiation and human settlement, of the involved fundamental physical concepts, and of the different technologies and applications of photovoltaic energy production, the authors propose an overview of the present situation and perspectives for the development of photovoltaic energy production (evolution and emergence of a competitive industry in several countries, recent and future evolutions of photovoltaic cell costs, needs of investments in massive electric power production). Then, they address the intermittency issue: integration into networks, consumption steering, perspective of a revolution in storage. They examine whether industrials are ready to face potential future revolutions

    Directory of Open Access Journals (Sweden)

    Baudouin C.

    2006-12-01

    Full Text Available Malgré une conjoncture globalement médiocre, du fait notamment de la crise asiatique et d'un hiver clément dans l'hémisphère nord, l'année 1997 a confirmé les signes d'amélioration de l'activité du raffinage observés en 1996. Mais la situation de ce secteur n'est pas encore satisfaisante : faible rentabilité des capitaux employés, préoccupations quant aux financements des investissements nécessaires à la protection de l'environnement. Pour 1998, la chute des cours des pétroles bruts, qui a évidemment pour corollaire une baisse des prix des produits, a été finalement plutôt favorable aux marges. Deux éléments modèrent ce relatif optimisme : d'une part le maintien d'une très grande volatilité, d'autre part l'accentuation de la crise économique et financière observée au cours de l'été, qui s'est traduite par une forte chute des marges dans toutes les zones géographiques et plus particulièrement en Asie. Début 1999, les marges de raffinage sont restées faibles et ont conduit à une baisse du taux d'utilisation des capacités de traitement. Despite a business environment that was globally mediocre due primarily to the Asian crisis and to a mild winter in the northern hemisphere, the signs of improvement noted in the refining activity in 1996 were borne out in 1997. But the situation is not yet satisfactory in this sector: the low return on invested capital and the financing of environmental protection expenditure are giving cause for concern. In 1998, the drop in crude oil prices and the concomitant fall in petroleum product prices was ultimately rather favorable to margins. Two elements tended to put a damper on this relative optimism. First of all, margins continue to be extremely volatile and, secondly, the worsening of the economic and financial crisis observed during the summer made for a sharp decline in margins in all geographic regions, especially Asia. Since the beginning of 1999, refining margins are weak and utilization rates of refining capacities have decreased.

    One end closed thoria-yttria solid electrolyte have been fabricated by the slip casting technique. A systematic study of the influence of the process parameters on the characteristics of the final bodies has been carried out. Slips of ThO 2 -10 mole % Y 2 O 3 were prepared; their fluidity and castability were studied as a function of concentration, pH and particle size. The bodies were sintered at 2000degC and the physical properties like density and microstructure were evaluated. Slip cast bodies of bulk densities around 95% T.D. with relatively inhomogenous but predominantly fine grained structure could be obtained by optimizing the process variables.

    Paruz, H.

    1963-05-01

    The work is carried out on U-Pu alloys in the region of the solid solution uranium alpha and in the two-phase region uranium alpha + the zeta phase. The results obtained concern mainly the influence of the addition of plutonium on the physical properties of the uranium (changes in the crystalline parameters, the density, the hardness) in the region of solid solution uranium alpha. In view of the discrepancies between various published results as far as the equilibrium diagram for the system U-Pu is concerned, an attempt was made to verify the extent of the different regions of the phase diagram, in particular the two phased-region. Examinations carried out on samples after various thermal treatments (in particular quenching from the epsilon phase and prolonged annealings, as well as a slow cooling from the epsilon phase) confirm the results obtained at Los Alamos and Harwell.

  6. It is possible to increase by over thirty per cent the Nile Water availability

    International Nuclear Information System (INIS)

    Lemperiere, F.

    2011-01-01

    The population of the Nile catchment is presently 250 Million and will probably reach 400 Million in 2040. The catchment includes two parts of about same population but with a very different climate. - The upstream rainy part (most of this area is in Ethiopia, Uganda and South Sudan). - The downstream dry part i.e North Sudan and Egypt. The available water from the Nile runoff is evaluated as average as 72 Billion m 3 /year; it is quite totally coming from the upstream part and used in the downstream part. For their development the upstream populations (including also part of Tanzania, Kenya, Congo, Rwanda and Burundi) are now requiring a significant share of the run off generated from local rains when Egypt and North Sudan claim historic rights on the Nile Waters. The best way to avoid conflicts is to increase the water availability for keeping in Egypt and North Sudan at least the water volume presently used and to allow to upstream countries the water resources necessary for their development, possibly in the range of 100 m 3 / year / capita in 2030 or 2040. The average total runoff of the Nile is in fact close to 140 Billion m 3 / year but over 40 Billion evaporate in the South Sudan Swamps and 15 Billion in the reservoirs of Aswan and Northern Sudan. A solution for reducing by half these two main losses is presented in this paper: it is based upon a concrete knowledge of the local very specific data and upon a successful experience of adapted technical solutions

  2. You say you want a revolution: casing drilling targets 30 per cent well-cost saving

    Energy Technology Data Exchange (ETDEWEB)

    Polczer, S.; Marsters, S.

    1999-10-01

    Casing drilling is a new method of drilling that eliminates drill strings by using standard casing to simultaneously drill and case wells. Tesco Corporation of Calgary acquired patent rights to casing drilling technology in 1995. The company now offers a conversion kit for existing drill rigs as well a new compact casing drilling rig for shallow markets. The single derrick will be rated at 1,500 meters, but initially it will be used to drill 700-800 meter gas wells in southeast Alberta. Some cost savings will be realized at these shallow depths, but the real cost saving advantages will be realized on deep holes. In the meantime, improvements are planned to the cutting structures of the under-rimming bit to increase safety and withstand higher torque loads. It will be also necessary to adapt techniques such as directional drilling and logging to the casing drilling conveyance mechanism which has been only partially successful thus far, especially in the retrieving mode. Another challenge already met, involved ensuring that casing could be run in high-compression loads without damage to connections. Despite these problems, the system attracted considerable attention with several international companies placing orders for immediate delivery. Another system, this one developed by Sperry-Sun Drilling Services and known as a 'casing while drilling' (CWD) system, is strictly a downhole assembly and is targeted for offshore use and deeper vertical holes. This system is currently being tested in two commercial operations in offshore Indonesia for Unocal Corporation. Despite numerous problems to fill casing with fluid during connections, penetration rates of 300-400 feet per hour were achieved.

  9. A new device for 100 per cent humidification of inspired air

    Science.gov (United States)

    Larsson, Anders; Gustafsson, Ann; Svanborg, Lennart

    2000-01-01

    Introduction: Devices for active humidification of the inspired air in mechanically ventilated patients cause water condensation in the ventilator tubing, which may become contaminated or interfere with the function of the ventilator. The present study describes and tests the performance of a new humidifier, which is designed to eliminate water condensation. Objectives: To test the performance of the new humidifier at different ventilator settings in a lung model, and to compare this new humidifier with a conventional active humidifier in ventilator-treated critically ill patients. Materials and methods: The humidifier (Humid-Heat; Louis Gibeck AB, Upplands Väsby, Sweden) consists of a supply unit with a microprocessor and a water pump, and a humidification device, which is placed between the Y-piece and the endotracheal tube. The humidification device is based on a hygroscopic heat-moisture exchanger (HME), which absorbs the expired heat and moisture and releases it into the inspired gas. External heat and water are then added to the patient side of the HME, so the inspired gas should reach 100% humidity at 37°C (44 mg H2O/l air). The external water is delivered to the humidification device via a pump onto a wick and then evaporated into the inspired air by an electrical heater. The microprocessor controls the water pump and the heater by an algorithm using the minute ventilation (which is fed into the microprocessor) and the airway temperature measured by a sensor mounted in the flex-tube on the patient side of the humidification device. The performance characteristics were tested in a lung model ventilated with a constant flow (inspiratory:expiratory ratio 1:2, rate 12–20 breaths/min and a minute ventilation of 3–25 l/min) or with a decelerating flow (inspiratory:expiratory ratio 1:2, rate 12–15 breaths/min and a minute ventilation of 4.7–16.4 l/min). The device was also tested prospectively and in a randomized order compared with a conventional active humidifier (Fisher & Paykel MR730, Auckland, New Zealand) in eight mechanically ventilated, endotracheally intubated patients in the intensive care unit. The test period with each device was 24 h. The amount of fluid consumed and the amount of water in the water traps were measured. The number of times that the water traps were emptied, changes of machine filters, the suctions and quality of secretions, nebulizations, and the amount of saline instillations and endotracheal tube obstruction were recorded. In order to evaluate increased expiratory resistance due to the device, the airway pressure was measured at the end of a prolonged end-expiratory pause at 1 h of use and at the end of the test, and was compared with the corresponding pressure before the experiment. The body temperature of the patient was measured before and after the test of each device. Results: Both with constant flow and decelerating flow, the Humid-Heat gave an absolute humidity of 41–44 mgH2O/l at 37°C, with the lower level at the highest ventilation. In the patients, both Humid-Heat and the conventional active humidifier (MR730) maintained temperatures, indicating that they provided the intended heat and moisture to the inspired air. With both devices, the body temperature was maintained during the test period. There was no difference in the amount of secretions, the quality of the secretions and the frequency of suctions, saline instillations or nebulizations between the test periods with the two devices. There was no endotracheal tube obstruction, and after 1 h of use and at the end of the test no increased airway resistance was found with either device. When the MR730 was used, however, the water traps needed to be emptied six to 14 (mean eight) times (total amount of fluid in the traps was 100–300 ml) and the machine filters were changed two to six (mean four) times due to an excessive amount of condensed water with flow obstruction. No condensation of water was found in the tubing with the Humid-Heat. The water consumption was 23–65 ml/h (mean 30 ml/h) with the MR730 and 4–8 ml/h (mean 6 ml/h) with the Humid-Heat (P < 0.0008). The same relations were found when the water consumption was corrected for differences in minute ventilation. Discussion: The new humidifier, the Humid-Heat, gave an absolute humidity of 41–44 mg/l at 37°C in the bench tests. The tests in ventilated patients showed that the device was well tolerated and that condensation in the tubing was eliminated. There was no need to empty water traps. The test period was too short to evaluate whether the new device had any other advantages or disadvantages compared with conventional humidifiers. PMID:11056746

  19. An innovative use of marine energies can economically produce fifteen per cent of electricity

    International Nuclear Information System (INIS)

    Lemperiere, F.

    2013-12-01

    After having outlined some interesting characteristics and opportunities of marine energies, the author analyses the peculiarities of tidal energy, presents the different components of tidal power stations: tanks or basins, plants (horizontal bulb-turbines, orthogonal turbines). Then, he focuses on an innovative solution: tidal gardens which can be created as closed basins along the coast comprising channels equipped with tidal turbines, and sea walls. Performance of such an installation is assessed. Issues of production gain by pumping, of connection to the grid and energy storage are addressed. The construction modality is described. Visual impacts, impact on the environment, direct and indirect social-economic impacts are discussed. The issue of ship navigation is also addressed. The example of the Somme Bay is presented and assessed in terms of production, of costs (turbines, channels, main sea wall), of impacts, and of possible additional wind turbines. Other potential and more or less important sites in France, in Great-Britain, in India, Bangladesh and Korea, in America (Canada, Argentina, Brazil) and notably in Australia are identified and briefly assessed

  11. Computer simulation of quenching uranium-0.75 weight per cent titanium alloy

    1986-01-01

    A ''QUENCH SIMULATOR'' has been developed which uses finite difference heat transfer and finite element stress analysis techniques to predict the behavior of a metal during quenching. The actual nonlinear temperature- and microstructure-dependent physical, thermophysical, and mechanical properties are incorporated as input into the computer model as well as the continuous cooling transformation (CCT) behavior and heats of transformation of the alloy. The final output provides the transient temperature distribution, details the final residual profile, predicts and shows where distortion occurs, and maps out the microstructure distribution throughout the entire sample. These data are available in tabulated form, contour plots, or color-coded graphics. This analysis has been demonstrated on simple shapes for unalloyed uranium and the uranium-0.75 weight per titanium alloy which undergoes a martensite transformation and is quench-rate sensitive. The results of this study are discussed in detail in addition to other applications of this analysis approach which is generic in nature

  13. It is possible to increase by over thirty per cent the Nile Water availability

    Energy Technology Data Exchange (ETDEWEB)

    Lemperiere, F.

    2011-01-15

    The population of the Nile catchment is presently 250 Million and will probably reach 400 Million in 2040. The catchment includes two parts of about same population but with a very different climate. - The upstream rainy part (most of this area is in Ethiopia, Uganda and South Sudan). - The downstream dry part i.e North Sudan and Egypt. The available water from the Nile runoff is evaluated as average as 72 Billion m{sup 3} /year; it is quite totally coming from the upstream part and used in the downstream part. For their development the upstream populations (including also part of Tanzania, Kenya, Congo, Rwanda and Burundi) are now requiring a significant share of the run off generated from local rains when Egypt and North Sudan claim historic rights on the Nile Waters. The best way to avoid conflicts is to increase the water availability for keeping in Egypt and North Sudan at least the water volume presently used and to allow to upstream countries the water resources necessary for their development, possibly in the range of 100 m{sup 3} / year / capita in 2030 or 2040. The average total runoff of the Nile is in fact close to 140 Billion m{sup 3} / year but over 40 Billion evaporate in the South Sudan Swamps and 15 Billion in the reservoirs of Aswan and Northern Sudan. A solution for reducing by half these two main losses is presented in this paper: it is based upon a concrete knowledge of the local very specific data and upon a successful experience of adapted technical solutions

    This article gives an overview of what will have to be done on the site of Fukushima to decontaminate and to dismantle it. Based on the experience gained in Three Mile Island and in Chernobyl, experts foresee ten years of work within the reactor cores, thirty years around the plant, sixty years of decontamination within the no man's land area around the plant; and centuries as far as scattered spots are concerned more than hundred kilometres away from the plant. Three radionuclides must be surveyed, but with different half lives: iodine 131 (8 days), caesium 137 (30 years), and plutonium 239 (24000 years). The expertise of French companies (Areva, Assystem, Bouygues and Vinci) in reactor dismantling, dismantling procedure design, and public works (protection arch like in Chernobyl) is briefly evoked, as well as the French approach for post-accident management

    The work is carried out on U-Pu alloys in the region of the solid solution uranium alpha and in the two-phase region uranium alpha + the zeta phase. The results obtained concern mainly the influence of the addition of plutonium on the physical properties of the uranium (changes in the crystalline parameters, the density, the hardness) in the region of solid solution uranium alpha. In view of the discrepancies between various published results as far as the equilibrium diagram for the system U-Pu is concerned, an attempt was made to verify the extent of the different regions of the phase diagram, in particular the two phased-region. Examinations carried out on samples after various thermal treatments (in particular quenching from the epsilon phase and prolonged annealings, as well as a slow cooling from the epsilon phase) confirm the results obtained at Los Alamos and Harwell. (author) [French] L'etude porte sur des alliages U-Pu du domaine de la solution solide uranium alpha et du domaine biphase uranium + phase zeta. Les resultats obtenus concernent en premier lieu l'influence de l'addition de plutonium sur les proprietes physiques de l'uranium (changement des parametres cristallins, densite, durete) dans le domaine de la solution solide uranium alpha. Compte tenu des divergences entre les differents resultats publies en ce qui concerne le diagramme d'equilibre du systeme U-Pu, on a essaye ensuite de verifier l'etendue des differents domaines du diagramme des phases, en particulier du domaine biphase zeta + uranium alpha. Les examens par micrographie et par diffraction des rayons X des echantillons apres differents traitements thermiques (notamment trempe a partir de la phase epsilon et recuits prolonges, ainsi qu'un refroidissement lent etage a partir de la phase epsilon) confirment les resultats obtenus a Los Alamos et a Harwell.

  6. Tendances récentes des échanges commerciaux internationaux et des négociations internationales

    Directory of Open Access Journals (Sweden)

    Christophe Bellmann

    2010-03-01

    Full Text Available En 2009, les échanges commerciaux internationaux ont été dominés par la crise financière et économique la plus importante depuis plusieurs années. La production mondiale a reculé, tout comme le volume des échanges commerciaux internationaux. Malgré leur absence de responsabilité dans cette crise, les pays en développement les plus pauvres ont aussi été les plus affectés. La Chine, le Brésil et l’Inde ont vu leurs exportations diminuer d’un quart à un tiers au cours du second semestre 2008, mais les pays ne faisant pas partie du groupe des 20 premiers pays en développement exportateurs ont été encore plus touchés. Le commerce et le PIB recommencent à croître, mais certains économistes s’attendent à une récession à double creux. Si le chômage continue d’augmenter, il se pourrait que les gouvernements aient plus de mal à résister aux pressions protectionnistes. Concernant les négociations à l’OMC, la crise est à double tranchant. Les gouvernements font face à des préoccupations plus immédiates, mais la crise a fait renaître le spectre du protectionnisme, rendant un accord commercial d’autant plus nécessaire. Le groupe des 20 premières économies du monde (G-20 a appelé à la conclusion du Cycle de Doha en 2010. Reste à savoir si ces promesses porteront leurs fruits. Le nombre d’accords bilatéraux continue de croître – la Suisse y participe d’ailleurs avec enthousiasme. Certains de ces accords ont été critiqués notamment parce qu’ils contiennent des obligations qui vont au-delà de celles prescrites par l’OMC, en particulier dans le domaine de la propriété intellectuelle. En attendant, il est tout à fait raisonnable de dire que le programme du Cycle de Doha ne reflète pas de nombreux problèmes actuels, en particulier la question des changements climatiques. Alors que les Etats-Unis et l’UE menacent d’imposer des droits de douane sur les importations en provenance d’économies émergentes ne disposant pas de plafond d’émissions de CO2, il est clair que les gouvernements doivent trouver un moyen de discuter des nouveaux défis auxquels l’économie mondiale doit faire face.

  11. Was there significant tax evasion after the 1999 50 cent per pack cigarette tax increase in California?

    Science.gov (United States)

    Emery, S; White, M; Gilpin, E; Pierce, J

    2002-01-01

    Objectives: Several states, including California, have implemented large cigarette excise tax increases, which may encourage smokers to purchase their cigarettes in other lower taxed states, or from other lower or non-taxed sources. Such tax evasion thwarts tobacco control objectives and may cost the state substantial tax revenues. Thus, this study investigates the extent of tax evasion in the 6–12 months after the implementation of California's $0.50/pack excise tax increase. Design and setting: Retrospective data analysis from the 1999 California Tobacco Surveys (CTS), a random digit dialled telephone survey of California households. Main outcome measures: Sources of cigarettes, average daily cigarette consumption, and reported price paid. Results: Very few (5.1 (0.7)% (±95% confidence limits)) of California smokers avoided the excise tax by usually purchasing cigarettes from non- or lower taxed sources, such as out-of-state outlets, military commissaries, or the internet. The vast majority of smokers purchased their cigarettes from the most convenient and expensive sources: convenience stores/gas (petrol) stations (45.0 (1.9)%), liquor/drug stores (16.4 (1.6)%), and supermarkets (8.8 (1.2)%). Conclusions: Despite the potential savings, tax evasion by individual smokers does not appear to pose a serious threat to California's excise tax revenues or its tobacco control objectives.

    This paper uses survey data for 60,000 households from 29 transition economies in 2006 and 2010 to explore how the use of banking services is related to household characteristics, as well as to bank ownership, deposit insurance and creditor protection. At the household level we find that the holding of a bank account, a bank card, or a mortgage increases with income and education in most countries and find evidence for an urban-rural gap. The use of banking services is also related to the rel...

  20. "Treatises on Earthquakes" in late Renaissance (16th-17th cent), at the roots of historical seismology

    Science.gov (United States)

    Albini, P.

    2009-04-01

    It was soon after the damaging November 1570 earthquake at Ferrara, Northern Italy, that the academic Stefano Breventano from Pavia, a small town in Northern Italy as well, started to compose his "Treatise on the earthquake". Completed by September 1576, this 250-page manuscript was to remain unpublished for centuries. The critical edition recently appeared (Albini, 2007) was a due tribute to the remarkable amount of information put together by Breventano, an otherwise "obscure" literate who, before getting involved with earthquakes, had published a history of the antiquities and remarkable events at his hometown Pavia (1570). Indeed, he was not the first Renaissance author to pursue the goal of checking into the historical sources of the previous centuries in search of earthquakes and other natural phenomena. What is outstanding in his "Treatise" is that he suceeded in retrieving information on more than two hundred earthquakes, along two thousand years, between 504 B.C. and 1575 A.D., covering the whole Euro-Mediterranean region, and the West Indies in early 16th century. Breventano's essay is here presented, together with a comparison between his style and amount of information with those included in the work by the contemporary British author Stephen Batman, "The Doome warning all men to the Judgement" (1581). A later treatise is presented also, the work by Marcello Bonito (1690) "Terra Tremante [Trembling Earth]", which could easily be defined as a worldwide list of earthquakes. In structure and content, Bonito's work goes along the same lines of Breventano, and could be considered a precursor of today descriptive catalogues, because of his outstandingly modern approach that paved the way to modern historical seismology.

    Electrically small antennas (ESAs) are becoming one of the key components in the compact wireless devices for telecommunications, defence, and aerospace systems, especially for the spherical one whose geometric layout is more closely approaching Chu's limit, thus yielding significant bandwidth improvements relative to the linear and planar counterparts. Yet broad applications of the volumetric ESAs are still hindered since the low cost fabrication has remained a tremendous challenge. Here we report a state-of-the-art technology to transfer electrically conductive composites (ECCs) from a planar mould to a volumetric thermoplastic substrate by using pad-printing technology without pattern distortion, benefit from the excellent properties of the ECCs as well as the printing-calibration method that we developed. The antenna samples prepared in this way meet the stringent requirement of an ESA (ka is as low as 0.32 and the antenna efficiency is as high as 57%), suggesting that volumetric electronic components i.e. the antennas can be produced in such a simple, green, and cost-effective way. This work can be of interest for the development of studies on green and high performance wireless communication devices.

    Full Text Available Gold and uranium tailings (‘slimes’ dams and the adjacent polluted soils in the deep-level mining regions of South Africa (Carletonville, Klerksdorp and Welkom were surveyed for the frequency of occurrence of naturally colonizing, actively introduced and persisting plant species. Fifty-six tailings dams with a combined area of 5864 ha. and a similar area o f tail- ings-polluted soils, were surveyed between July 1996 and March 1997. During the survey, 376 plant species and subspecies were recorded from the dams and adjacent polluted soils, with an additional  8 6  records obtained between 1998 and 2003 (i.e. a total of 462 taxa: species and infraspecific species. Overall, the most commonly represented families were the Poaceae (107 species and subspecies, Asteraceae (81. Fabaceae (55 and Anacardiaceae (16. with other families represented by just one to 14 species. Only 60 species were common to all three regions, and of these 24 had been introduced during rehabilitation attempts. Most of the species found on tailings were persisters or natural colonizers (53-88%, depending on substrate, with the vast majority being indigenous and perennial taxa (76% and 85% respectively, with semi-woody to woody growth forms (6 6% being resprouters, forbs, shrubs and trees. Less than 4% of the naturally-colonizing taxa found during the survey had also been introduced by vegetation practitioners. The majority of introduced plants were alien herbaceous taxa. The number and frequency of annuals was only high on recently vegetated sites, whereas annuals were rarely present on old-vegetated and never-vegetated dams. This list includes a wide range of indigenous plant species that may be suitable for phytoremediation of tailings dams and polluted soils due to their apparent tolerance of acid mine drainage and salinity.

    2006-11-01

    Full Text Available L'évolution du raffinage vers une utilisation des produits pétroliers pour les usages des transports et comme base pour la pétrochimie renforce l'intérêt pour les procédés de transformation des fractions lourdes du pétrole en fractions légères correspondant au marché actuel. Les problèmes posés par le raffinage des résidus de distillation sont semblables à ceux rencontrés pour le traitement des bruts lourds non conventionnels. Les méthodes qui sont actuellement envisagées peuvent être classées en 2 catégories : les méthodes de raffinage avec rejet de carbone comme la cokéfaction et le désasphaltage et les méthodes sans rejet de carbone comme la viscoréduction, l'hydroviscoréduction et l'hydrotraitement catalytique. Chacune de ces techniques est examinée en précisant les rendements en produits liquides qu'elle permet d'atteindre et les hydrotraitements complémentaires nécessaires pour obtenir des produits répondant aux spécifications du marché des produits pétroliers. Les progrès réalisés dans la conception des catalyseurs utilisés pour le traitement des produits lourds permet aujourd'hui d'envisager l'hydrotraitement direct des résidus sous vide de la majorité des bruts raffinés. The increasing use of refined petroleum products for transportation purposes and as petrochemical bases reinforces interest in processes for converting heavy fractions into light fractions suitable for today's market. The refining of distillation residues involves difficulties similar to unconventional heavy-crude processing. As of now methods may be classified in two categories: (i refining methods with carbon rejection such as coking and deasphalting processes, and (ii methods without carbon rejection such as visbreaking, hydrovisbreaking and catalytic hydrotreating. Each of these techniques is examined, taking into account the liquid-product yields it may reach, and the additional hydrotreatments necessary to meet market specifications. Advances made in designing catalysts for heavy-fraction processing now make it possible to envisage the direct hydrotreatment of vacuum residues from the majority of crudes available.

    2006-11-01

    Full Text Available L'Institut Français du Pétrole a travaillé depuis plus de 20 ans pour développer une méthode scientifique de forage. L'effort entrepris s'est avéré d'autant plus nécessaire que les puits deviennent plus profonds et plus inclinés, voire horizontaux. Le système est basé dans une première étape sur une transmission par fil des données de fond et le contrôle de fonctions également au fond. Trois composants principaux ont été réalisés : - une sonde directionnelle ; - une unité de mesure des paramètres de forage au fond ; - un raccord coudé à angle variable. La sonde directionnelle est de type magnétique et accélérométrique. L'unité de mesure des paramètres de forage a différents capteurs pour mesurer les paramètres utiles, elle est complètement compensée pour les effets de pression. Le raccord coudé à angle variable est basé sur la rotation de la partie basse du raccord autour d'un axe incliné. Les résultats commerciaux pour la sonde directionnelle et les résultats d'essais pour les autres composants sont présentés. Le fonctionnement des équipements a été satisfaisant. Ces équipements fournissent une base solide pour réaliser des outils parfaitement fiables. Une brève discussion sur les avantages des systèmes à fil et à transmission par la boue est présentée. Dans le futur, en plus de la commercialisation des outils existants en 7 3/4 , des prototypes sont en cours de réalisation en d'autres diamètres. Un raccord pour effectuer des mesures de diagraphies est également en cours de réalisation. Efforts in remote controlled drilling have been made at the Institut Français du Pétrole for over twenty years to design a scientific way of drilling. This is particularly needed as the wells go deeper and are more slanted, sometimes horizontal. The research is based in a first stage on a wireline transmission of bottomhole data and control of downhole functions. Three main parts have been built: - a directionnal unit, - a bottomhole drilling parameters measuring unit, - a variable angle bent sub. The directional unit is of the magnetic-accelerometric type. The bottomhole measuring unit has varions sensors to measure the parameters needed and is fully pressure compensated. The variable angle bent sub is based on the rotation of the lower part of a sub around a titled axis. The commercial results for the directionnal unit and the test results for the other composents are preseneted. The functionning of these equipements is satisfactory and gives a good ground for designing full proof items. A brief discussion of the advantages of hard wire and mud transmission system ispresented. ln the future, besides marketing existing industrialized tools, design of tools in diameters other that the 7 3/4 O. D selected for the prototypes will be undertaken. Sensors for measuring logging parameters and safety parameters will be added.

Le discoglosse peint (Discoglossus pictus et la grenouille taureau (Rana catesbeiana sont les deux seules espèces étrangères dont l'introduction a conduit à une naturalisation. La tortue de «Floride» (Trachemys scripta elegans pourrait bien suivre prochainement la même voie. Certaines espèces françaises ont, par contre, été introduites avec succès en métropole, hors de leurs aires d'indigénat. Les causes connues de ces introductions sont liées à des opérations à but économique (commerce, à caractère socioculturel (loisirs ou à fondement scientifique (expériences. Ces opérations n'ont cependant généralement pas pour but l'introduction volontaire d'une espèce dans le milieu naturel, celle-ci résultant plutôt de négligences. Certaines introductions involontaires ont pu aussi avoir pour origine un transport passif (par exemple, par voie maritime. Des conséquences négatives de ces introductions sont suspectées, mais ne sont généralement pas démontrées. Elles peuvent s'inscrire dans les catégories suivantes : compétition avec une espèce autochtone, prédation excessive sur une ou plusieurs espèces autochtones, pollution génétique, introduction de maladies ou de parasites.

    2012-06-01

    Full Text Available Phenomenology of religion is among the oldest branches of the discipline founded by Husserl. It has always been difficult to define its outlines: from the very first essays of Scheler, Reinach and Heidegger to the so-called “theological turn” of French phenomenology, one has always feared the transformation of the phenomenology of religion in a religious philosophy that would give up the sacred principle of neutrality. This situation is perhaps behind us thanks to the recent endeavors to renew the field of research. French and American specialists of Husserl’s thought Natalie Depraz and Anthony J. Steinbock try to push back the limits of and to explore new ways in genetic phenomenology by describing religious attitudes by mean of a philosophical-existential methodology especially designed for this task. This paper introduces what might open of a new era of the phenomenology of religion.

Du fait que dans les domaines de gîtes de houille en exploitation les réserves de houille ne suffiront pas à assurer à long terme un rendement d'extraction suffisant, on commença une vaste exploration dans des parties de quartier encore inconnues. Il fut ainsi possible d'élargir considérablement les connaissances sur la situation géologique des gîtes de houille grâce à des études par réflexion sismique, des forages profonds et des enregistrements de forages géophysiques. An accurate inventory of the coal beds was dependent upon the reorganization of property reports in the Ruhr region (Ruhrkohle Fondation AG. Because the working coal fields do not contain sufficient coal reserves to guarantee satisfactory productivity rates on a long-term basis, extensive exploration in previously unexplored parts of the area was undertaken. Thus, it became possible to extend considerably our knowledge of the geological structure of the coal beds through refraction shooting, deep drilling, and the well logging.

    Full Text Available This paper reports a study case showing integrated analyses of microscopic records from an archaeological site of southern Italy. Pollen and non pollen palynomorphs-NPPs were found in archaeological layers and were basic in reconstructing both the past environment and the economic activities of the site. The site, Fattoria Fabrizio, is a modest 4th-cenury BC farmhouse of the chora (rural territory of the Greek city (polis of Metaponto (Basilicata. Pollen analyses in addition to the study of NPPs have been particularly worthwhile for palaeoenvironmental and palaeoeconomical reconstructions of this site and others in the chora. The pollen spectra delineate an open plant landscape, with scanty woodlands and presence of local wet environments. Olea pollen is fairly well represented in all samples, suggesting that this tree was an important element of the agricultural economy of the chora. Shrubby grasslands and a well-developed maquis characterized the territory, probably as result of grazing activities by sheep and goats. Accordingly, the high percentages of Poaceae and Cichorieae pollen, together with coprophilous fungal spores (such as Sordaria type and Sporormiella type, suggest that pastoral activities were widely practiced. The low number of Cerealia pollen grains suggests that the inhabitants’ fields covered small areas or were quite far from the farmhouse.

    Carole Birkan-Berz

    2009-05-01

    Full Text Available Up until Tenebrae, the sonnet had been given a prominent place in Geoffrey Hill’s work. Relying on a slightly modernised form harking back to the Renaissance, Hill used it as a vehicle for metaphysical questioning on the nature of poetry, violence or religion. In more recent volumes, however, the form seemed to have disappeared, only to survive in a palimpsestic way. Surprisingly, Hill’s last two collections feature a return to the sonnet, with its twin themes of amorous discourse and political eloquence. Though for the most part shunning rhyme and rigid stanzaic format, the sonnets retain syllabic lines and a dialectical structure typical of the genre. The flexible placing of the volta, the use of a coda, as well as some of the thematics following on from The Orchards of Syon, point to Milton as Hill’s main influence, as well as to Coleridge and Wordsworth, as practitioners of the political sonnet. Moreover, the appearance of the autobiographical lyric ‘I’ in these sonnets as in recent collections points to the persistence of a Romantic ethos, of which the poet had been suspicious in his early writing. The sonnet, with a fresh autobiographical ‘I’ and a renewed political dimension, thus re-anchors Hill in a Romantic tradition.

    2011-02-01

    Full Text Available La description de l’île de Bilāq chez le géographe al-Idrīsī, au xiie siècle, tranche nettement avec les récits de ses prédécesseurs et ne correspond que très partiellement à l’îlot de Philae auquel Bilāq est d’ordinaire identifiée. Alors qu’elle est normalement située légèrement en amont de la première cataracte, Bilāq devient chez Idrīsī une immense île localisée bien en amont de la Vallée, en plein pays nubien, au confluent du Nil et d’un fleuve provenant d’Éthiopie. Les commentateurs modernes s’accordent à reconnaître qu’il y a là un amalgame probable avec la région de l’interfluve Nil-Atbara, sans parvenir pour autant à en comprendre les raisons. Cet article s’efforce précisément d’examiner les sources et les méthodes mises en œuvre par le géographe de Sicile afin d’éclairer la généalogie de cette confusion. Celle-ci repose en dernier lieu sur la difficulté à adapter des informations hétérogènes, dont une partie au moins est issue d’entretiens oraux avec des voyageurs, au cadre ptoléméen dans lequel Idrīsī entend les fondre. L’île de Bilaq se superpose alors au souvenir rémanent de l’île de Méroé, figure majeure de la géographie ptoléméenne du Haut Nil.The 12th-century description of Bilāq Island by al-Idrisi contrasts with his predecessors’ accounts and only partly fits the small island of Philae with which Bilāq was usually identified. Bilāq, normally placed a little above the first cataract, became, for al-Idrīsī, a big island located much farther upstream in the land of Nubia, at a place where a river coming from Ethiopia flowed into the Nile. Modern commentators agree that this description probably came out of a confusion with the Nile-Atbara area but are unable to explain the reasons for this. This article inquires into al-Idrisi’s description, into both the sources and methods used by this geographer. It intends to shed light on the origins of this confusion, which ultimately has to do with the difficulty that al-Idrīsī had adapting heterogeneous sources of information (including interviews with travelers to his Ptolemaic conception. The island of Bilāq thus came to be mixed up with lingering recollections of the island of Meroe, a major figure in the Ptolemaic geography of the upper Nile Valley.

    We apply four statistical learning methods to a sample of 7941 galaxies (z test the feasibility of using automated algorithms to classify galaxies. Using 10 features measured for each galaxy (sizes, colours, shape parameters, and stellar mass), we apply the techniques of Support Vector Machines, Classification Trees, Classification Trees with Random Forest (CTRF) and Neural Networks, and returning True Prediction Ratios (TPRs) of 75.8 per cent, 69.0 per cent, 76.2 per cent, and 76.0 per cent, respectively. Those occasions whereby all four algorithms agree with each other yet disagree with the visual classification (`unanimous disagreement') serves as a potential indicator of human error in classification, occurring in ˜ 9 per cent of ellipticals, ˜ 9 per cent of little blue spheroids, ˜ 14 per cent of early-type spirals, ˜ 21 per cent of intermediate-type spirals, and ˜ 4 per cent of late-type spirals and irregulars. We observe that the choice of parameters rather than that of algorithms is more crucial in determining classification accuracy. Due to its simplicity in formulation and implementation, we recommend the CTRF algorithm for classifying future galaxy data sets. Adopting the CTRF algorithm, the TPRs of the five galaxy types are : E, 70.1 per cent; LBS, 75.6 per cent; S0-Sa, 63.6 per cent; Sab-Scd, 56.4 per cent, and Sd-Irr, 88.9 per cent. Further, we train a binary classifier using this CTRF algorithm that divides galaxies into spheroid-dominated (E, LBS, and S0-Sa) and disc-dominated (Sab-Scd and Sd-Irr), achieving an overall accuracy of 89.8 per cent. This translates into an accuracy of 84.9 per cent for spheroid-dominated systems and 92.5 per cent for disc-dominated systems.

    Lower extremity vascular trauma (LEVT) is a major cause of amputation. A clear understanding of prognostic factors for amputation is important to inform surgical decision-making, patient counselling and risk stratification. The aim was to develop an understanding of prognostic factors for amputation following surgical repair of LEVT. A systematic review was conducted to identify potential prognostic factors. Bayesian meta-analysis was used to calculate an absolute (pooled proportion) and relative (pooled odds ratio, OR) measure of the amputation risk for each factor. Forty-five studies, totalling 3187 discrete LEVT repairs, were included. The overall amputation rate was 10·0 (95 per cent credible interval 7·4 to 13·1) per cent. Significant prognostic factors for secondary amputation included: associated major soft tissue injury (26 versus 8 per cent for no soft tissue injury; OR 5·80), compartment syndrome (28 versus 6 per cent; OR 5·11), multiple arterial injuries (18 versus 9 per cent; OR 4·85), duration of ischaemia exceeding 6 h (24 versus 5 per cent; OR 4·40), associated fracture (14 versus 2 per cent; OR 4·30), mechanism of injury (blast 19 per cent, blunt 16 per cent, penetrating 5 per cent), anatomical site of injury (iliac 18 per cent, popliteal 14 per cent, tibial 10 per cent, femoral 4 per cent), age over 55 years (16 versus 9 per cent; OR 3·03) and sex (men 7 per cent versus women 8 per cent; OR 0·64). Shock and nerve or venous injuries were not significant prognostic factors for secondary amputation. A significant proportion of patients who undergo lower extremity vascular trauma repair will require secondary amputation. This meta-analysis describes significant prognostic factors needed to inform surgical judgement, risk assessment and patient counselling. © 2015 BJS Society Ltd Published by John Wiley & Sons Ltd.

The deliveries of domestic heating oil and heavy fuel oils increased by 4 per cent and 28 per cent respectively. Motor gasoline increased by 3 per cent while the deliveries of diesel oil decreased by 1 per cent. The consumption of fuels in mining and manufacturing decreased by 5 per cent during 2001 compared with 2000. Most of the reduction came from the lower use of domestic fuel in manufacture of pulp, paper and paper products, printing and publishing. The total consumption in mining and manufacturing was unchanged during the 4 th quarter 2001 compared with the same period 2000. The consumption of domestic fuels decreased by 6 per cent and the oil consumption increased by 11 per cent. Higher consumption of fuels in electricity, gas and district heating services. The consumption of fuels in electricity, gas and district heating services increased by 14 per cent 2001 compared with 2000. The consumption of domestic fuels raised with 12 per cent and the use of fossil fuels raised with 17 per cent. The highest increasing, 27 per cent, was found within the use of oil. Electricity, gas and district heating services increased there fuel consumption with 29 per cent during the 0 quarter 2001 compared with the same period 2000. The raise can be explained with the fact that the 4th quarter 2000 was unusually warm. The increasing is found both in the use of domestic and fossil fuels

    Two hundred and seventeen patients who had sustained an injury during the recreational use of a trampoline were managed in the emergency room of Logan Regional Hospital in Logan, Utah, from January 1991 through December 1992. We retrospectively reviewed the charts and radiographs of these patients to categorize the injuries. Additional details regarding the injuries of seventy-two patients (33 per cent) were obtained by means of a telephone interview with use of a questionnaire. The injuries occurred from February through November, with the peak incidence in July. The patients were eighteen months to forty-five years old (average, ten years old); ninety-four patients (43 per cent) were five to nine years old. Eighty-four patients (39 per cent) sustained a fracture; fifty-four (25 per cent), a sprain or strain; forty-five (21 per cent), a laceration; and thirty-four (16 per cent), a contusion. Fifty-seven injuries (26 per cent) involved the elbow or forearm; forty-six (21 per cent), the head or neck; forty (18 per cent), the ankle or foot; thirty-three (15 per cent), the knee or leg; nineteen (9 per cent), the trunk or back; thirteen (6 per cent), the shoulder or arm; and nine (4 per cent), the wrist or hand. Thirteen patients (6 per cent) had a back injury, but none of them had a permanent neurological deficit. One patient who had an ocular injury was transferred to a tertiary care center. One hundred and fifty-six patients (72 per cent) were evaluated radiographically, fifteen (7 per cent) were admitted to the hospital, and thirteen (6 per cent) had an operation.(ABSTRACT TRUNCATED AT 250 WORDS)

    28 Patients with colon carcinoma (excluding the recto-sigmoid region) underwent preoperative staging with computed tomography (CT). The CT had a sensitivity of 60 and 67 per cent for detection of extramural invasion, 75 per cent sensitivity and specificity for lymph node metastases and a sensitivity of 87 per cent and specificity of 95 per cent for liver metastases. Compared with the modified Dukes classification, CT correctly staged 50 per cent of the patients with Dukes A lesions; 40 per cent with Dukes B, 75 per cent with Dukes C and 85 per cent with Dukes D lesions. The data presented in this study showed that CT has limitations in the sensitivity and accuracy of staging local colonic carcinoma. However, the authors recommend its use for patients who are clinically suspected of having extensive disease. (author). 10 refs.; 4 figs.; 2 tabs
