    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.

    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.

    2007-01-01

    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

    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

    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.

    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.

  19. 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

    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

  5. 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.

  6. Highlighting micrographic structures of uranium alloys containing 0.5 to 10 per cent wt molybdenum

    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

  7. 99 cent: Price Points in E-Commerce

    2010-01-01

    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 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.

    2016-09-01

    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

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

    2015-08-01

    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.

  13. Power-To-Gas is not indispensable to reach a 100 per cent renewable

    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

  14. Nitrous oxide emissions from cropland: a procedure for calibrating the DayCent biogeochemical model using inverse modelling

    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.

  17. Is 50 cent the price of the optimal copayment? - a qualitative study of patient opinions and attitudes in response to a 50 cent charge on prescription drugs in a publicly funded health system in Ireland

    Directory of Open Access Journals (Sweden)

    2013-01-01

    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.

    2007-07-01

    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'.

    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.

    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.

    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.)

    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 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.

    1997-01-01

    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

  10. Warm-hot baryons comprise 5-10 per cent of filaments in the cosmic web.

    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.

  11. Evaluation of the DayCent model to predict carbon fluxes in French crop sites

    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.

    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.

    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

    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

    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)

    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.

    2011-01-01

    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).

    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

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

    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

    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 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)

    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.

  5. 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.

    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

    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.

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

    Science.gov (United States)

    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

    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

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

    1989-01-01

    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

    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.

    Full Text Available Le présent article de revue concerne des acquisitions récentes dans le domaine de l’electrophysiologie des cellules productrices d’insuline. D’abord, dans le cadre de la participation des canaux anioniques sensibles au volume cellulaire, en particulier l’anoctamine 1, au processus de stimulation de la sécrétion d’insuline par le glucose, les modifications de l’activité bioélectrique de cellules insulaires soumises à l’hexose provoquées par l’acide tannique sont exposées. Les modifications du potentiel de membrane provoquées par la carbamylcholine en présence d’une concentration physiologique de glucose sont ensuite prises en considération. Enfin, l’accent est mis sur les aspects bioélectriques de l’activation par le sucralose du récepteur au goût sucré TIR 3 présent dans les cellules productrices d’insuline. Les implications physiopathologiques d’une telle activation sont également évoquées.

    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.

    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.

    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...

    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.

    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.

    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)

    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

    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.

    Abscesses of odontogenic origin in guinea pigs pose a serious health problem and need to be treated with a combination of surgical and medical therapy. The aim of this prospective study was to describe the microbial flora of odontogenic abscesses associated with osteomyelitis in 24 pet guinea pigs, to perform antibiotic sensitivity testing, and to make recommendations for practitioners on the antibiotics of first choice. Inclusion criteria for the study included the animal being diagnosed with an odontogenic abscess which underwent surgery and was not pre-treated with an antibiotic. Inclusion criteria matched for 24 guinea pigs. Samples (pus, capsule and affected tooth/bone) for bacteriological examination were collected under sterile conditions during the surgical procedure. The most commonly isolated bacteria from abscesses of odontogenic origin were Bacteroides fragilis in 12.8 per cent (6/47) of cases, Pasteurella multocida in 10.6 per cent (5/47) and Peptostreptococcus anaerobius in 8.5 per cent (4/47). Aerobic bacterial species only were isolated in 29.2 per cent (7/24) of cases, anaerobic bacteria only were isolated in 33.3 per cent (8/24), and mixed infection with anaerobic and aerobic bacterial species was seen in 37.5 per cent (9/24). Aerobes (n=20) were sensitive to enrofloxacin and marbofloxacin in 100 per cent of samples, benzylpenicillin potassium (penicillin G, PNCG) in 90 per cent, cephalotin in 85 per cent, amoxicillin-clavulanate in 75 per cent, doxycycline in 70 per cent, gentamicin in 65 per cent and trimethoprim-sulfamethoxazole in 55 per cent. Anaerobes (n=27) were sensitive to amoxicillin-clavulanate in 100 per cent of cases, clindamycin in 96.3 per cent, metronidazole in 92.6 per cent, PNCG in 92.6 per cent and cephalotin in 74.1 per cent. As guinea pigs are strictly herbivorous animals, based on the results of this study the recommended antibiotic treatment for odontogenic abscesses is a combination of fluoroquinolones and metronidazole

    With a view to their use in the exchangers of nuclear reactors of the graphite-gas or heavy water-gas types, the behaviour of chromium-aluminium steels containing up to 7 per cent chromium and 1.5 per cent aluminium has been studied in the presence of high-pressure carbon dioxide at temperatures of between 400 and 700 deg. C. The two most interesting grades of steel (2 per cent Cr - 0.35 per cent Al - 0.35 per cent Mo and 7 per cent Cr - 1.5 per cent Al - 0.6 per cent Si) are still compatible with carbon dioxide up to 550 and 600 deg. C respectively. A hot dip aluminised coating considerably increases resistance to oxidation of the first grade and should make possible its use up to temperatures of at least 600 deg. C. (authors) [French] Dans l'optique de leur emploi dans les echangeurs de reacteurs nucleaires des filieres graphite-gaz ou eau lourde-gaz, le comportement en presence de gaz carbonique sous pression d'aciers au chrome-aluminium, contenant jusqu'a 7 pour cent de chrome et 1,5 pour cent d'aluminium a ete etudie entre 400 et 700 deg. C. Les deux nuances les plus interessantes (2 pour cent Cr - 0,35 pour cent Al - 0,35 pour cent Mo et 7 pour cent Cr - 1,5 pour cent Al - 0,6 pour cent Si) restent compatibles avec le gaz carbonique jusqu'a 550 et 600 deg. C respectivement. Un revetement d'aluminium, effectue par immersion dans un bain fondu, ameliore notablement la resistance a l'oxydation de la premiere et doit permettre son empioi jusqu'a 600 deg.

    550 Patients were entered into a set of dose-searching studies designed to determine normal tissue tolerances to high energy (42-66 MeV reactions) fast neutrons delivered in 12 equal fractions over 4 weeks. Patients were stratified by treatment facility and then randomized to receive 16, 18 or 20 Gy for tumors located in the upper abdomen or pelvis, and 18, 20 or 22 Gy for tumors located in the head and neck, thorax or extremities. Following completion of the randomized protocols, additional patients were studied at the 20.4 Gy level in the head and neck, thorax and pelvis. Normal tissue effect scoring was accomplished using the RTOG-EORTC acute and late normal tissue effect scales. Acute Grade 3+ toxicity rates in the head and neck were 19 per cent for 20/20.4 Gy and 20 per cent for 22 Gy. Time adjusted late toxicity rates in the head and neck at 12 months were 15 per cent for 20/20.4 Gy and 0 per cent for 22 Gy. The 18 Gy treatment arm of the head and neck protocol was dropped early in the study after only two patients were accrued. For cases treated in the thorax, acute Grade 3+ toxicity rates were 6 per cent for 18 Gy, 15 per cent for 20/20.4 Gy and 7 per cent for 22 Gy. Late toxicity rates at 12 months were 0 per cent for 18 Gy, 11 per cent for 20/20.4 Gy and 18 per cent for 22 Gy. Acute Grade 3+ toxicity rates in the upper abdomen were 0 per cent for 16 Gy, 18 per cent for 18 Gy and 12 per cent for 20 Gy. There were no Grade 3+ late toxicities in the upper abdomen. In the pelvis acute Grade 3+ toxicity rates were 0 per cent for 16 Gy, 3 per cent for 18 Gy and 3 per cent for 20/20.4 Gy. Late Grade 3+ toxicities at 24 months were 20 per cent for 16 Gy, 5 per cent for 18 Gy and 24 per cent for 20/20.4 Gy. In the extremities, acute Grade 3+ toxicity rates were 7 per cent for 20 Gy and 21 per cent for 22 Gy, while at 12 months, late Grade 3+ toxicity rates were 14 and 35 per cent respectively. The 18 Gy treatment arm of the extremities protocol was dropped early

    Between 1977 and 1988, 67 patients underwent surgical removal of residual metastatic deposits following an aggressive chemotherapy regimen (cisplatin, vincristine, methotrexate and bleomycin alternating with etoposide, actinomycin D and cyclophosphamide) for disseminated germ cell tumours of the testis (stage IIB or above). Ninety-one surgical procedures were performed. There were 63 (69 per cent) retroperitoneal lymph node dissections, 16 (18 per cent) thoracotomies, three (3 per cent) hepatic resections, three (3 per cent) craniotomies, five (5 per cent) delayed orchidectomies and one anterolateral decompression of the vertebral column. Nine (13 per cent) patients required a repeat retroperitoneal node dissection and one patient needed a repeat thoracotomy to remove recurrent metastatic deposits during the period of follow-up. Multivisceral resections and vascular reconstruction procedures were required in 20 (30 per cent) patients undergoing retroperitoneal node dissection. Fifty-five (82 per cent) patients remain in complete remission with a mean follow-up period of 49.6 months (range 2-121 months). Nine (13 per cent) patients died with metastatic disease between 2 months to 4 years after operation. There were three deaths in the perioperative period (4 per cent). The histology of the resected metastases revealed undifferentiated active tumour in 20 (30 per cent) patients, differentiated mature teratoma in 29 (43 per cent) patients and fibrosis/necrosis in 18 (27 per cent) patients. Twelve (60 per cent) patients with undifferentiated elements and 15 patients (60 per cent) with raised preoperative tumour markers (poor prognostic categories) are in complete remission. Cytoreductive surgery in patients with metastatic germ cell tumours offers the best chance of remission following chemotherapy even in poor prognostic group categories.

    The study presents a comprehensive statistical analysis of a series of 500 consecutive rhinoplasties of which 380 (76 per cent) were primary and 120 (24 per cent) were secondary cases. All cases were operated upon using the external rhinoplasty technique; simultaneous septal surgery was performed in 350 (70 per cent) of the cases. Deformities of the upper two-thirds of the nose that occurred significantly more in the secondary cases included; dorsal saddling, dorsal irregularities, valve collapse, open roof and pollybeak deformities. In the lower third of the nose; secondary cases showed significantly higher incidences of depressed tip, tip over-rotation, tip asymmetry, retracted columella, and alar notching. Suturing techniques were used significantly more in primary cases, while in secondary cases grafting techniques were used significantly more. The complications encountered intra-operatively included; septal flap tears (2.8 per cent) and alar cartilage injury (1.8 per cent), while post-operative complications included; nasal trauma (one per cent), epistaxis (two per cent), infection (2.4 per cent), prolonged oedema (17 per cent), and nasal obstruction (0.8 per cent). The overall patient satisfaction rate was 95.6 per cent and the transcolumellar scar was found to be unacceptable in only 0.8 per cent of the patients.

    2006-12-01

    Report presents the latest information on relations and trends in the Croatian energy sector. The reports gives a familiar overview of comprehensive data about and representative features of the Croatian energy sector, related to the supply and demand of energy at all levels. It produces a detailed analysis of energy trends and provides extensive data on capacity, reserves and prices as well as balances of individual energy sources - crude oil, petroleum products, natural gas, electricity, heat, coal and renewable source of energy. Basic economic and financial indicators, emissions of air pollutants and basic energy efficiency indicators for Croatia are also presented. In 2005, total primary energy supply in Croatia decreased slightly by 0.1 per cent with respect to the previous year. At the same time, GDP rose by 4.3 per cent, resulting in a drop in energy intensity of the total primary energy supply of 4.2 per cent. The energy intensity in Croatia was 20.1 per cent higher than the average energy intensity in the European Union, but a positive decreasing trend was noted during the past period. In 2005 the total primary energy production in Croatia fell by 3.5 per cent with respect to the previous year. The highest decrease was recorded in harnessing hydro power, and the production of crude oil and fuel wood also declined. Only the production of natural gas showed a growth of 3.5 per cent. Due to the decrease in the primary energy production, energy self-supply was also reduced to 47.9 per cent. A less value was achieved only in the year 2003. A continuing trend towards a gradual decline in energy self-supply was present throughout the past several years. Final energy demand increased by 3 per cent while demands in other sectors decreased. Energy transformation losses were reduced by 7 per cent, non-energy use declined by 5.6 per cent and energy transmission and distribution losses by 5.5 per cent, and there was a slight drop of 0.2 per cent in demand in energy

  3. Fuels. Deliveries and consumption of fuels during 4th quarter 2001 and during 2001

    International Nuclear Information System (INIS)

    2002-01-01

    The total volume of oil product deliveries (excluded lubricants, bitumen etc.) from the oil companies was 3 per cent higher during 2001 compared with 2000. The deliveries of motor gasoline and diesel oil increased by 1 per cent. Domestic heating oil decreased by 2 per cent and heavy fuel oils increased by 17 per cent, all compared with 2000. Under the forth quarter 2001 the deliveries of oil products (excluded lubricants bitumen etc.) was 5 per cent higher compared with the same quarter 2000. 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

    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.

    2012-02-03

    We investigated the long-term outcome of treatment in 159 patients with hyperthyroidism first seen between 1979 and 1992. Median duration of follow-up was 10 1\\/2 years. We also inquired into current practice for the follow-up of hyperthyroidism by other endocrinologists in Ireland. Seven cases of unrecognised hyperthyroidism (4 per cent) and one of unrecognised hypothyroidism were identified. Among patients with Graves\\' disease, of those treated with an antithyroid drug, 28 per cent were in remission, 68 per cent had relapsed and 4 per cent had become hypothyroid. Of those treated by sub-total thyroidectomy, 31 per cent were in remission, 19 per cent had relapsed, 19 per cent were hypothyroid and 31 per cent were sub-clinically hypothyroid. Among patients treated with radioiodine, 19 per cent were euthyroid, 3 per cent were still hyperthyroid and three-quarters had become hypothyroid. In contrast, after radioiodine for toxic nodular goitre, 63 per cent were euthyroid and only 32 per cent had become hypothyroid (Chi Squared v. Graves\\' disease, P = 0.001). Of 73 patients receiving thyroxine replacement, plasma TSH was normal in only 41 per cent, although 82 per cent of patients had been seen by the family doctor within the previous 12 months. Seven of 17 other endocrinologists undertook long-term follow-up of hyperthyroid patients in their specialist clinics but none was using a computerised system to co-ordinate this. The findings confirm that careful follow-up is required for all hyperthyroid patients. The family doctor is well positioned to undertake this, but education and auditing are required.

    Preliminary research has been carried out on a series of vanadium-based alloys: V, 0.5 per cent Si; V, 5 per cent Ca; V, 5 per cent Mo; V, 5 per cent Nb; V, 2 per cent Zr; V, 20 per cent Ti; V, 10 per cent Al; V, 10 per cent Sn and v, 10 per cent Ti liable to be used as canning material in fast reactors. The transformation by forging at about 1000 deg. C and rolling between 200 deg. C and room temperature is satisfactory for all types of alloys except V with 10 per cent Sn and V with 10 per cent Al. The mechanical properties deduced from tensile strength tests carried out on alloy samples annealed 1 hour at 1050 deg. C in a vacuum show that, generally speaking, the addition elements lead to an improvement in these properties as compared to those of pure vanadium. After undergoing corrosion tests in a liquid sodium loop purified by a cold trap, the alloys become brittle at room temperature. Only the vanadium containing 20 per cent Ti keeps its plastic properties. These alloys are covered by a layer of vanadium carbide VC. After undergoing treatment in a liquid sodium loop purified by a hot trap, all the alloys keep their good mechanical characteristics. The surface layer with which they are covered is composed of two vanadium carbides VC and {sub {gamma}}VC, and a vanadium sub-oxide VO{sub 0.9}.

    Fertility parameters of boar spermatozoa were evaluated in vitro, after freeze-thawing the semen in three different extenders containing permeable and non-permeable cryoprotectants: A (111.0 mM Tris, 31.4 mM citric acid, 185.0 mM glucose, 20 per cent egg yolk, 3 per cent glycerol and 100 iu/ml penicillin G); B (200 mM Tris; 70.8 mM citric acid, 55.5 mM glucose, 20 per cent egg yolk, three per cent glycerol and 100 iu/ml penicillin G); C (200 mM Tris, 70.8 mM citric acid, 55.5 mM fructose, 20 per cent egg yolk, 3 per cent glycerol and 100 iu/ml penicillin G). The freeze-thawing techniques were the same for each extender. Eight ejaculates from four boars were obtained; the sperm-rich fraction of each ejaculate was extended in each of the three media at a final concentration of 400 x 106 sperm/ml, loaded into 0.5 ml straws and frozen at a rate of 30 degrees C/minute to -196 degrees C. The straws were thawed at 60 degrees C for eight seconds. Sperm motility, acrosomal integrity and in vitro sperm penetration through the zona pellucida of gilt oocytes matured in vitro were evaluated. The motility of unfrozen spermatozoa was 93.1 per cent compared with 60.7 per cent, 48.2 per cent and 35 per cent for sperm frozen in extenders A, B and C respectively; these values were all significantly different (Pextender A, but there were significant decreases in sperm motility after 30 minutes of incubation in B and C. The percentage acrosomal integrities were 97.2 per cent for the control and 45.5 per cent, 30.3 per cent and 16.8 per cent for the frozen-thawed spermatozoa in extenders A, B and C respectively. The results of the in vitro penetration assay were 80.7 per cent when using control spermatozoa, and 42.2 per cent, 18.4 per cent and 3.3 per cent when using frozen-thawed spermatozoa in extenders A, B and C respectively

    The frequency of infection in 197 patients undergoing elective colorectal surgery and having either no blood transfusion, transfusion with whole blood, or filtered blood free from leucocytes and platelets was investigated in a prospective randomized trial. Natural killer cell function was measured...... before operation and 3, 7 and 30 days after surgery in 60 consecutive patients. Of the patients 104 required blood transfusion; 48 received filtered blood and 56 underwent whole blood transfusion. Postoperative infections developed in 13 patients transfused with whole blood (23 per cent, 95 per cent...... confidence interval 13-32 per cent), in one patient transfused with blood free from leucocytes and platelets (2 per cent, 95 per cent confidence interval 0.05-11 per cent) and in two non-transfused patients (2 per cent, 95 per cent confidence interval 0.3-8 per cent) (P less than 0.01).

    Acute herpes simplex virus (HSV) infection was detected in 23 of 102 consecutively examined, sexually active male homosexuals who presented with anorectal pain, discharge, tenesmus, or hematochezia, as compared with 3 of 75 homosexual men without gastrointestinal symptoms (P less than 0.01). Findings that were significantly more frequent in men with HSV proctitis than in men with proctitis due to other infectious causes included fever (48 per cent), difficulty in urinating (48 per cent), sacral paresthesias (26 per cent), inguinal lymphadenopathy (57 per cent), severe anorectal pain (100 per cent), tenesmus (100 per cent), constipation (78 per cent), perianal ulcerations (70 per cent), and the presence of diffuse ulcerative or discrete vesicular or pustular lesions in the distal 5 cm of the rectum (50 per cent). Serologic evidence indicated that 85 per cent of the men with symptomatic HSV proctitis were having their first episode of HSV-2 infection. The diagnosis of HSV proctitis is suggested by the presence of severe anorectal pain, difficulty in urinating, sacral paresthesias or pain, and diffuse ulceration of the distal rectal mucosa.

    No prospective studies including large numbers of dogs with acute haemorrhagic diarrhoea syndrome (AHDS) are published so far. The aim of this case-control study was to describe signalment, history, clinical signs, laboratory values and course of disease in dogs with AHDS. Dogs (108) with idiopathic acute haemorrhagic diarrhoea (schnauzer and Maltese. The syndrome was more likely to occur during winter. Vomiting preceded the onset of bloody diarrhoea in 80 per cent of dogs and haematemesis was observed in half of those cases. Median AHDS index at presentation was 12 (range 3-17). Haematocrit was generally high (median 57.1 per cent; range 33-76 per cent), but exceeded 60 per cent only in 31.4 per cent of dogs. Haematocrit of 48.1 per cent of dogs was above reference range, as was monocyte (50.0 per cent), segmented (59.6 per cent) and band neutrophil count (45.2 per cent). A rapid clinical improvement occurred during the first 48 hours. British Veterinary Association.

    Clinical endometritis is an important disease of dairy cattle and results in decreased reproductive performance. This disease is caused by contamination of the uterus with a broad spectrum of microorganisms after calving. In this study, staphylococcal isolates from the uterus of dairy cows with clinical endometritis were tested for their distribution of superantigen (SAg) genes and antimicrobial resistance. Between the 127 staphylococcal isolates collected in this study, 10 species were identified. The predominant strain identified was Staphylococcus aureus (n=53), followed by Staphylococcus saprophyticus (n=38) and Staphylococcus chromogenes (n=22). PCR analysis demonstrated that most isolates (63.0 per cent) harboured at least one SAg gene. The most commonly observed SAg gene and genotype was selj (38.6 per cent) and sec-selj-seln (24.0 per cent), respectively. Most isolates were resistant to penicillin (79.5 per cent), ampicillin (71.7 per cent), erythromycin (56.7 per cent), and tetracycline (52.0 per cent). PCR analysis demonstrated that the antimicrobial resistance determinants ermA, ermB, ermC, tetK, tetM and blaZ were detected in 0 per cent, 44.4 per cent, 51.4 per cent, 68.2 per cent, 13.6 per cent and 86.1 per cent of the erythromycin, tetracycline and β-lactam resistant isolates, respectively. There were 22 (17.3 per cent of all isolates) coagulase-negative staphylococci shown to be methicillin resistant. In the methicillin-resistant isolates, significant resistances to ampicillin, erythromycin and penicillin were observed (P<0.01). The results of this study demonstrate that staphylococci recovered from dairy cows with clinical endometritis contain an extensive and complex prevalence of SAg genes. Significant resistances to antibiotics were also seen, highlighting the need for the rational appliance of antibiotics in veterinary medicine. British Veterinary Association.

    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

    Post-qualification salaries have increased by 4-7 per cent, a slowdown on last year's figures when increases were often more than 10 per cent. The highest increases this year tended to be in medium-sized trusts where newly qualified accountants' salaries rose 8.2 per cent. Directors of finance in large trusts earn about 20 per cent more than in medium trusts and about 40 per cent more than in small ones. Newly qualified accountants in large trusts earn 5 per cent more than in medium-sized trusts and 13 per cent more than in small ones. The survey is based on an analysis of salaries from Hays' jobs database, and salaries of registered candidates.

  15. 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.

    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.

    From 1974 to 1979, the rehabilitation centers of the association "Le Patriarche" located in the country side of southern France, have received 446 chronic polydrugs users who has consumed at one time or an other cannabis (marihuana, hashish) (87 p. cent), LSD (66 p. cent) and other hallucinogens (35 p. cent), psychodepressants (55 p. cent), psychostimulants (amphetamines, 85 p. cent; cocaïne, 50 p. cent) and opium and its derivatives (brown sugar, 47 p. cent; opiates, 67 p. cent; heroin, 50 p. cent). The dominant addictive drug was heroin and opiates, 52 p. cent, psychodepressants (barbitutiques and benzodiazepines, 33 p. cent, psychostimulants, 15 p. cent. Males were twice as numerous as female. Average age was 21 (range 14-38). Mean duration of drug abuse was 7 years. All these drug abusers display at entrance withdrawal symptoms. These were treated successfully by a drug free, psycho-physiological regimen comprising: 1. An elimination of all psychoactive drugs, including coffee, and alcohol. Tobacco was permitted. 2. Physical therapy (bath, exercise, massage) and forced fluid diuresis. 3. A supportive psychotherapy dispensed by rehabilitated addicts who had undergone successfully a similar regimen. This non-pharmacological method of treating withdrawal symptoms associated with opium, barbiturate and amphetamine addiction, was successful, and was not associated with any major clinical symptoms threatening the vital signs. Mean duration of detoxification was 5 days for opiates, 6 days for amphetamines and 10 days for barbiturates. 78 p. cent of these subjects remained in the centers from 3 months to 2 years, partaking in physical occupational and physiological rehabilitation paograms which allowed then to adopt a drug free life style and prepared them for social reinsertion.

  18. Classification of radioactive wastes produced by the nuclear industry

    2013-01-01

    This document first indicates the origins of radioactive wastes (mainly electronuclear industry), and the composition of spent fuel, and that only fission products and minor actinides are considered as radioactive wastes whereas uranium and plutonium can be used as new fuel after recycling. The classification of radioactive wastes is indicated in terms of radioactivity level and radionuclide half-life: high level (0.2 per cent of the total waste volume but 96 per cent of total waste radioactivity), medium level long life (3 per cent of volume, 4 per cent of radioactivity), low level long life (7 per cent of volume, 0.1 per cent of radioactivity), low and medium level and short life (63 per cent of volume and 0.02 per cent of radioactivity), very low level (27 per cent of volume and less than 0.01 per cent of radioactivity). An overview of radioactive waste processing and storage in France is presented for each category. Current and predicted volumes are indicated for each category. The main challenges are briefly addressed: spent fuel recycling, waste valorisation by fourth-generation reactors. Processing locations in France and in the World are indicated. Some key figures are provided: 2 kg of radioactive waste are produced per inhabitant and per year, and waste management costs represent 5 per cent of the total cost of produced electricity

    1996-01-01

    A 17.9 per cent increase over 1995 in oil and gas revenues were reported for Alberta through August 1996. Revenues from crude oil were up 12.6 per cent and from natural gas 30.7 per cent. The level of increase in revenues is expected to hold for the remainder of the year, save for the prospects of Iraq re-entering the market in force. This would cause a steep decline in prices and some panic trading in energy stocks. Nevertheless, producers are well positioned for the year ahead, as capital spending and drilling activity are based on lower price forecasts. Oil production over 1995 was down slightly through August. Light and medium crude production was down 4.5 per cent. Synthetic production fell by 0.8 per cent. Natural gas production will have a record year. Through August output was up 4.6 per cent over 1995, sales were up 19.3 per cent, and exports were ahead by just under one per cent. Natural gas liquids were the biggest revenue booster, increasing by 46.3 per cent over 1995

    Efficiency of 32 P labelled ammonium nitrate phosphate (ANP) containding 30, 50 and 90 per cent of water-soluble phosphorus (WSP) vis-a-vis that of entirely water soluble monoammonium orthophosphate (MAP) for wheat and succeeding maize crop on deep black (vertisol), calcareous black (vertisol), alluvial-Tarai (mollisol) and grey brown alluvial (aridisol) soils was examined in greenhouse experiments. Data on wheat indicated that ANP (50 per cent WSP) was, in general, equally efficient to MAP and ANP (90 per cent WSP) in terms of drymatter yield and total uptake of phosphorus in all soils examined, however, the per cent utilization of applied fertilizer was significantly higher for MAP and ANP (90 per cent WSP) than those for ANP (50 per cent WSP) in all soils. In general, ANP (30 per cent WSP) was significantly inferior to MAP and ANP (90 per cent WSP) in all soils. Data on the succeeding maize crop grown to flowering indicated that residual value of ANP (30 per cent WSP) was equal to that of MAP and ANP (90 per cent WSP) in terms of drymatter yield and phosphorus uptake by the four soils examined. Complementary incubation studies conducted upto 60 days on the above four soils at field capacity moisture status indicated highest 0.5 M NaHCO 3 (pH 8.5) extractable phosphorus levels in MAP treatments followed by ANP (50 per cent WSP) and least in ANP (30 per cent WSP) treatments.

    Between 1985 and 1999, 43 patients with locally-advanced, resectable oropharyngeal cancer were treated with combined surgery and post-operative radiation therapy (RT) at Oregon Health and Science University. Five patients (12 per cent) had Stage III disease and 38 patients (88 per cent) had Stage IV disease. All patients had gross total resections of the primary tumour. Thirty-seven patients had neck dissections for regional disease. RT consisted of a mean tumour-bed dose of 63.0 Gy delivered in 1.8-2.0 Gy fractions over a mean of 49 days. At three- and five-years, the actuarial local control was 96 per cent and the actuarial local/regional control was 80 per cent. The three- and five-year actuarial rates of distant metastases were 41 per cent and 46 per cent, respectively. The actuarial overall survival at three- and five-years was 41 per cent and 34 per cent, respectively. The actuarial rates of progression-free survival were 49 per cent at three-years and 45 per cent at five years. Combined surgery and post-operative RT for advanced-stage oropharyngeal cancer results in excellent local/regional control. This particular group of patients experienced a high-rate of developing distant metastases.

    A survey of 854 horse owners, trainers and equestrian managers in 10 regions of Great Britain and Ireland showed that 83 per cent provided their horses with routine prophylactic dental care at fixed intervals, including 49 per cent at intervals of 12 months and 30 per cent at intervals of six months; a further 10 per cent provided it only when they felt it was required and 7 per cent did not provide it at all. Overall, 44 per cent of the owners had their horse's wolf teeth (first premolar) extracted routinely; when prophylactic dentistry was provided, it was carried out solely by equine dental technicians (EDTS) for 53 per cent of owners, solely by veterinarians for 35 per cent, by both EDTS or veterinarians for 10 per cent of owners and by other than veterinarians or EDTS for 1 per cent. There was confusion among some horse owners concerning the qualifications of the EDTS, because no recognised British qualification was available until towards the end of this survey in 2001. Several reasons were cited by owners for choosing between veterinarians and EDTS including their perceived qualifications, personal recommendations, costs, the availability of a wide range of dental equipment and sedation, and the time and effort devoted to the procedures.

    To elicit the opinion of Puerto Rican medical students, residents and internal medicine faculty as to the appropriateness of euthanasia and physician-assisted suicide and end-of-life management. Survey using a 16-item questionnaire answered within a two-month period in the fall of 1996. Rounds or faculty meetings at teaching hospitals located in the north, south and southwest of the island of Puerto Rico. There were 424 participants. The questionnaires of 279 medical students, 75 medical residents, and 35 internal medicine faculty members were analyzed. Thirty-five questionnaires, which were incomplete or answered by non-Puerto Rican participants, were excluded. Frequency of support of active euthanasia, physician-assisted suicide, withholding or withdrawing life-sustaining treatment with informed consent was determined. Whether it was ethical to prescribe full doses of drugs needed to alleviate pain even if it would hasten death, or agree to limit or restrict resources for the terminally ill was also determined. Forty per cent of the students, 33% of the residents, and 20% of the faculty supported euthanasia. If physician-assisted suicide were legalized, 50 per cent of the students, 43 per cent of the residents and 45 percent of the faculty would not be opposed to it. Sixty-eight per cent of the students, 67 per cent of the residents and 88 per cent of the faculty would support withholding or withdrawing life-sustaining treatment for dying patients with informed consent. Seventy-nine per cent of residents, 80 per cent of the faculty but only 54 per cent of medical students would prescribe full doses of drugs needed to alleviate pain in dying patients even if they would hasten death. Thirty-six per cent of the residents and faculty would agree to limit the use of medical resources for the terminally ill but only sixteen per cent of medical students would do so. The acceptance of euthanasia was inversely proportional to the clinical experience of the respondents: 40

    1980-01-01

    Radio-immunoassay of serum gastrin may now be carried out in all laboratories of radio-immunology. Comparison of two commercial kits A: Schwartz-Mann and B: CEA-SORIN according to criteria of specificity, sensitivity and reproducibility within and between systems, shows that they both permit the detection of pathological hypergastrinemias (Zollinger Ellison and atropic gastritis). Both kits have an identical intrasystem coefficient of variation (10 p. cent and 7 p. cent fort A, 5 p. cent and 8 p. cent for B) on the other hand, the inter-system coefficient of variation is better for kit B (22.4 p. cent and 37 p. cent for kit A, and 11.5 p. cent and 14.2 p. cent for kit B). The normal values for each kit are quite different: 97 . 64 pg.ml -1 for A and 51 . 23 pg.ml -1 for B preventing one from comparing estimations carried out with two different kits [fr

    1945-01-01

    Bobwhite quail chicks, when given a choice of balanced diets in which the essential difference was the protein supplement, showed preferences for one diet containing 49 per cent peanut oil meal, another containing a mixture of 9 per cent meat and bone scraps (50% protein) with 38 per cent soybean oil meal, and a third (control) diet containing a mixture of 16 per cent dried buttermilk with 42 per cent soybean oil meal, in contrast to diets containing sardine meal or menhaden fish meal. ....Feeding tests during the first five weeks of life showed that diets containing 14 per cent sardine fish meal consistently gave high live weights, low mortality, and high efficiency of feed utilization. Diets with 9 to 10 per cent menhaden meal produced nearly as good results....Live weights, survival, and efficiency of feed utilization were markedly better on a diet containing 9 per cent meat and bone scrap (50% protein) than on one with 9 per cent meat scrap (55% protein), but not as good as with diets containing fish meal without meat....The chicks grew and survived more successfully on diets containing either soybean oil meal or peanut oil meal as the sole protein supplement, than on diets containing either linseed oil meal, cottonseed oil meal, or dried buttermilk as the sole protein concentrate. None of these was as satisfactory as the diets containing fish meal.....All chicks died on diets containing either linseed oil meal, cottonseed oil meal, or dried buttermilk as the sole source of protein. All three of these concentrates, however, gave satisfactory results, when used as 10 per cent of the diet. In fact, survival and efficiency of feed utilization were nearly as good on a diet containing 10 per cent dried buttermilk, 10 per cent linseed oil meal, 10 per cent peanut oil meal, and 27 per cent soybean oil meal, as on diets containing fish meal.

    We compared the recognition of tobacco brands and ever-smoking rates in young children before (1991) and after (2001) the implementation of cigarette advertising restrictions in Hong Kong and identified continuing sources of tobacco promotion exposure. A cross-sectional survey of 824 primary school children aged from 8 to 11 (Primary classes 3-4) living in two Hong Kong districts was carried out using self-completed questionnaires examining smoking behaviour and recognition of names and logos from 18 tobacco, food, drink and other brands common in Hong Kong. Ever-smoking prevalence in 2001 was 3.8 per cent (1991, 7.8 per cent). Tobacco brand recognition rates ranged from 5.3 per cent (Viceroy name) to 72.8 per cent (Viceroy logo). Compared with 1991, in 2001 never-smoker children recognized fewer tobacco brand names and logos: Marlboro logo recognition rate fell by 55.3 per cent. Similar declines were also seen in ever-smoker children, with recognition of the Marlboro logo decreasing 48 per cent. Recognition rates declined amongst both boys and girls. Children from non-smoking families constituted 51 per cent (426) of the sample, whereas 34.5 per cent (284), 8.5 per cent (70), 1.7 per cent (14) and 4.4 per cent (36) of the children had one, two, three or more than three smoking family members at home, respectively. Tobacco brand recognition rates and ever-smoking prevalence were significantly higher among children with smoking family members compared with those without. Among 12 possible sources of exposure to cigarette brand names and logos, retail stalls (75.5 per cent; 622), indirect advertisements (71.5 per cent; 589) and magazines (65.3 per cent; 538) were ranked the most common. Advertising restrictions in Hong Kong have effectively decreased primary-age children's recognition of tobacco branding. However, these children remain vulnerable to branding, mostly through exposure from family smokers, point-of-sale tobacco advertisement and occasional promotions

    2013-01-01

    Energy security concerns due to high oil import dependence and climate change concerns due to related greenhouse gas emissions are important policy discussions in India. Could life cycle assessment (LCA) of petroleum oil products provide inputs to crude oil sourcing and domestic oil pricing policies to address the two concerns? This paper presents a baseline study on LCA of petroleum products in India from Well to Storage depending on the oil source, type of refinery, product and the selected destinations. The LCA based GHG emissions are found to be higher by 4–12 per cent than GHG emissions from direct fuel consumption alone for LPG, 7–10 per cent for Gasoline, 3–9 per cent for Diesel and 4–10 per cent for Kerosene based on various supply chain routes supplying oil to six largest cities in India. Overall the energy used in oil exploration, refinery and transportation in the LCA have a share of 72–77 per cent, 11–15 per cent and 6–8 per cent, respectively. The paper proposes imposing a relative carbon cess for various oil products in different Indian cities. States could accommodate this additional carbon cess by reducing their respective state taxes without increasing the final delivery price to the consumers. - Highlights: ► LCA emissions are found to be higher by 4–12 per cent than direct fuel consumption emissions. ► Energy used in oil exploration, refinery and transportation in the LCA have a share of 72–77 per cent, 11–15 per cent and 6–8 per cent, respectively. ► Corresponding GHG emission shares are 60–66 per cent, 23–27 per cent and 5–8 per cent, respectively. ► The source of crude oil matters. E and P energy consumption is found highest for African countries. ► Differential carbon cess could be imposed without changing final delivery price to consumers

    Questionnaires on sexual function, marital status, and fertility were returned by 84 men who received radiotherapy for seminoma (Stage I, II, or III). The mean length of follow-up was ten years. Although 93 per cent were married, 19 per cent had low rates of sexual activity, 12 per cent reported low sexual desire, 15 per cent had erectile dysfunction, 10 per cent had difficulty reaching orgasm, and 14 per cent had premature ejaculation. The most common problems were reduced intensity of orgasm (33%) and reduced semen volume (49%). Twenty-one men remained childless, and 30 per cent of men worried at least occasionally about infertility. Thirteen children were conceived after cancer therapy. The data suggest that sexual dysfunction and infertility are important concerns for a subgroup of men treated for seminoma

    1999-01-01

    An increase of shelf life of onions (Var. Valencia Sintetica-14) irradiated with doses from 20 and 80 Gy was observed and this increase varied from 30 per cent to 50 per cent of the irradiated bulbs in relation to the controls. The smallest diminishment on daily weight was achieved with doses of 46.46 Gy and 67.30 Gy calculated through regression analysis on the first and second experiments respectively. In relation to the discarded onions, two parameters were taken into account: external visible sprouting and rotting. The sprouting decreased from 58.3 per cent in the controls down to 0 per cent at the doses of 80 and 120 Gy. The rotting was 41.7 per cent in the controls and increased to 100 per cent at the doses of 80 and 120 Gy respectively after 382 and 262 days by an increase of shelf life of 75.2 per cent and 29.1 per cent on both the experiments. The best dose for prolonging shelf life was considered to be 40 Gy reaching a 90.4 per cent longer life. (author)

    A 1-year prospective and observational study included all admissions (n=216) until 48 h after discharge to Alexandria PICU between first of May 2003 and end of April 2004. Cultures for bacteria and fungi and antibiotic sensitivity tests (19 antibiotic using Bauer-Kirby disc diffusion method) were obtained (blood, stool, urine and cerebrospinal fluid, if needed) and repeated on suspicion of NIs. All cannulae, endotracheal tube (ET) aspirates and tips, nasogastric tubes and different catheters were cultured. All PICU health care workers (HCWs) were subjected to throat and under-finger nails cultures as well as inanimate objects, both on bimonthly basis. The referral place (ward or emergency), PRISM III score, length of stay (LOS) and fate were recorded. Amongst those patients whose age ranged from 1 to 23 months, 23 per cent had NIs with infection rates of 40/1000 days. Significantly high rates of mortality, LOS and PRISM III score were encountered among patients with NIs (52 per cent vs 30 per cent; 9.4+/-4.8 vs 5.4+/-2.2 days; 14.4+/-7 vs 11.8+/-6 respectively). The descending order of frequency of NIs was blood stream infection (BSI) (47 per cent), urinary tract infection (UTI) (28 per cent), ventilator-associated pneumonia (VAP) (16 per cent) and meningitis (9 per cent). Gr-ve bacilli accounted for 76.7 per cent; Gr+ve cocci 13.3 per cent (with satisfactory sensitivity to cefepime, imipenem and meropenem) and Candida albicans 10 per cent of all NIs. The rate of NIs/1000 device days were: 18.7 per cent for BSI, 10.9 per cent for VAP and 25.5 per cent for UTI. Vulnerable age groups were >6 m for VAP and predictors of NI acquisition (odd ratio and 95 per cent confidence interval: 1.537, 1.423-1.659; 1.073, 1.041-1.105 and 0.269, 0.178-0.406 respectively). Bimonthly cultures for HCWs isolated coagulase-ve Staphylococci, while inanimate objects isolated diphtheroids and Candida albicans. NIs rate was high (23 per cent) mainly due to severity of condition on admission

    Effective mastitis control requires knowledge of the predominant pathogen challenges on the farm. In order to quantify this challenge, the aetiological agents associated with clinical mastitis in 30 milk-recording dairy herds in Ireland over a complete lactation were investigated. Standard bacteriology was performed on 630 pretreatment quarter milk samples, of which 56 per cent were culture-positive, 42 per cent culture-negative and 2 per cent contaminated. Two micro-organisms were isolated from almost 5 per cent of the culture-positive samples. The bacteria isolated were Staphylococcus aureus (23 per cent), Streptococcus uberis (17 per cent), Escherichia coli (9 per cent), Streptococcus species (6 per cent), coagulase-negative Staphylococci (4 per cent) and other species (1 per cent). A wide variety of bacterial species were associated with clinical mastitis, with S aureus the most prevalent pathogen overall, followed by S uberis. However, the bacterial challenges varied widely from farm to farm. In comparison with previous reports, in the present study, the contagious pathogens S aureus and Streptococcus agalactiae were less commonly associated with clinical mastitis, whereas, the environmental pathogens S uberis and E coli were found more commonly associated with clinical mastitis. While S aureus remains the pathogen most commonly associated with intramammary infection in these herds, environmental pathogens, such as S uberis and E coli also present a considerable challenge.

    Aggression against doctors involved in after-hours house calls (AHHC) is widely perceived to be high. It is, however, unclear how doctors who perform this service manage the risk of aggressive patients during home visits. The aim of this paper is to explore if and how doctors manage the risk of violence against them during AHHC. A survey was designed and administered to all 300 Australian-based doctors engaged in AHHC under the National Home Doctor Service (NHDS). The survey was conducted from September 2014 to November 2014. There were 172 responses (57.3 per cent). Only 43 per cent of respondents adopted personal protective measures. The remaining 57 per cent had none; of those 6 per cent had never considered protective measures, and 31.8 per cent were aware of the risk of violence, but were unsure of what to do. Measures adopted include the use of chaperones/security personnel (34.1 per cent), dependence on surgery policies (31.2 per cent), de-escalation techniques (15.2 per cent), panic buttons (7.2 per cent), personal alarms (6.1 per cent), and others (6.5 per cent). Females were more likely to adopt personal protective measures than males (OR 4.94; pdoctors were less likely to do so relative to overseas-trained doctors (OR 0.35; p=0.04; CI 0.12-0.99). Just over half of the doctors involved in AHHC took no precautions against aggressive attacks while on duty, and nearly one-third relied on the policies of their employing surgeries.

    This study was carried out to assess the accuracy of three devices namely, liquid crystal forehead, digital electronic axillary and infrared tympanic thermometer, using a glass-mercury rectal thermometer as the control. The subjects were two hundred children aged 0-48 months. The mean rectal temperature was 38.0 +/- 0.91 degrees C; forehead, 37.83 +/- 0.94 degrees C; tympanic, 37.77 +/- 0.95 degrees C, and axillary, 37.71 +/- 0.86 degrees C. Compared to the rectal temperature, all values were significantly lower (p < 0.05). Forehead, tympanic and axillary temperature differed from rectal temperature by at least 0.5 degrees C in 33.33 per cent, 23.5 per cent and 31.5 per cent of subjects, and at least 1 degrees C in 22 per cent, 1 per cent and 6 per cent of subjects respectively. Accuracy in detection of fever was 79 per cent for forehead, 85.5 per cent for tympanic and 84 per cent for axillary thermometry. Sensitivity of the three devices was 67-83 per cent in detection of fever and 64-77 per cent in detection of high fever. Tympanic thermometry had the best performance while forehead thermometry had the poorest. After using revised diagnostic threshold temperature by ROC curves, sensitivity of each device improved but accuracy was nearly the same. It is concluded that the three devices are not suitable as a substitute for a glass-mercury rectal thermometer in assessment of fever in infants and young children.

    Postal surveys or personal interviews of 76 recent veterinary graduates and their 49 employers were undertaken to establish their perceptions of good practice when integrating a new graduate into a business and their preferred methods of assessment and development. Practice type and location were the main influences on graduates looking for their first job. Interviews were mostly informal. Employers expected basic veterinary competence and candidates expected good quality support. Most graduates (93 per cent) had their own consultations on the first day. During early consultations 2 per cent of senior vets accompanied the new graduate, 95 per cent of practices provided senior back-up either in person or by telephone but in 3 per cent no back-up was available. Most new graduates (90 per cent) were satisfied with their workload. Three-fifths were on-call within the first week, and 95 per cent within a month. Graduates received calls directly in 45 per cent of practices, in 9 per cent seniors screened the calls, and the remainder used a third party. Assistance from experienced lay staff varied greatly. Discussion of problems was mainly informal. There was little spontaneous feedback and problems resulted from inadequate communication. One in three new graduates left their first job within two years, and one in six identified lack of support, heavy workload, stress or clashes with staff as a primary reason. This high turnover was a problem for employers. From the new graduates' perspectives, initial problems included: being on call (59 per cent), financial aspects (47 per cent) and surgery (43 per cent). Communicating with clients and learning to prioritise jobs were also difficult. New graduates took longer over procedures (79 per cent of employers commented) and required extra back-up (91 per cent) both of which reduced income (59 per cent). Nearly all the seniors felt that their current new graduates had coped 'quite well', although it was claimed that new graduates

    Fifty-three faecal samples from yellow-legged gulls (Larus cachinnans) at the Berlengas nature reserve in Portugal were cultured on Levine agar plates not supplemented with antimicrobial agents, and one Escherichia coli colony was isolated and identified from each sample. The percentages of resistant isolates for each of the drugs were ampicillin (43.4 per cent), tetracycline (39.6 per cent), nalidixic acid (34.0 per cent), streptomycin (32.1 per cent), trimethoprim-sulfamethoxazole (SXT) (26.4 per cent), ciprofloxacin (18.9 per cent), chloramphenicol (18.9 per cent), gentamicin (7.5 per cent), tobramycin (7.5 per cent) amikacin (5.7 per cent) and amoxicillin-clavulanic acid (1.9 per cent). All the isolates were susceptible to cefoxitin, ceftazidime, cefotaxime, aztreonam and imipenem. The following resistance genes were detected: bla(TEM) (17 of 23 ampicillin-resistant isolates), tet(A) and/or tet(B) (18 of 21 tetracycline-resistant isolates), aadA (12 of 17 streptomycin-resistant isolates), cmlA (all chloramphenicol-resistant isolates), aac(3)-II with or without aac(3)-IV (all four gentamicin-resistant isolates), and sul1 and/or sul2 and/or sul3 (all 14 SXT-resistant isolates). The intI1 gene was detected in 10 of 14 SXT-resistant isolates, and three of them also contained class 2 integrons; four different gene cassette arrangements were identified among class 1 integrons (aadA, dfrA1+aadA1, dfrA12+orfF+aadA2 and sat+psp+aadA2) and one among the class 2 integrons (dfrA1+sat+aadA1). Ninety per cent of the isolates were included in the A or B1 phylogenetic groups.

    2002-04-01

    Two hundred and twenty two hyperlipidemic patients were recruited for a 12-week prospective, multicenter, open-label, titrate-to-goal study to evaluate the efficacy and safety of 20 to 40 mg per day of simvastatin in a Thai population. The efficacy on lipid lowering was evaluated at 4 weeks and 8 weeks after medication. Based on NCEP ATP II guideline and ADA position statement, subjects were categorized into three groups according to LDL-C goals; group I: patients without CHD and with or = 2 CHD risk factors and group III: CHD patients or diabetic patients with > or = 1 risk factors. Significant changes of all lipid parameters from baselines were noted at 4 weeks after medication except for HDL-C levels. Reduction of serum LDL-C, TC and TG by 40 per cent, 29 per cent and 16 per cent respectively and increase of serum HDL-C by 5 per cent were observed at 8 weeks of therapy (p<0.05). At 4 weeks after taking simvastatin 20 mg/day, 78.9 per cent of patients in group I, 67.4 per cent in group II and 40.9 per cent in group III achieved LDL-C goals. Seventeen per cent of the patients who were evaluated at 8 weeks increased the simvastatin dosage to 40 mg per day in the second month of treatment. At 8 weeks of therapy with simvastatin 20-40 mg/day, 90.1 per cent of patients in group I, 77.4 per cent in group II and 66.7 per cent in group III achieved LDL-C goals. Adverse symptoms during therapy, mostly mild, developed in 6.3 per cent of the 222 patients. Simvastatin 20-40 mg/day was effective and well tolerated in managing lipid parameters in Thai patients similar to other ethnic populations.

    To comparatively evaluate the properties of two BPA-free experimental adhesives (EXA, EXB) for lingual fixed retainer bonding versus a commercially available reference material (Transbond LR-TLR) based on BPA-compound. The experimental materials were a flowable 60 per cent glass filler-filled UEDMA/TEGDMA flowable composite (EXB) and a 70 per cent glass filler-filled paste composite with PCDMA/UEDMA/TEGDMA co-monomers. The properties tested were degree of conversion (DC%), mechanical properties (Martens hardness-MH, elastic modulus-E IT , elastic index-n IT ), effect of prolonged (6 months) water storage (changes in Vickers microhardness-VHN) and pull-out strength employing a multi-stranded wire. EXB showed the highest DC% (63.6 per cent), followed by EXA (50.5 per cent) and TRL (44.1 per cent), with all means differences being statistically significant (P EXA (53MPa; 12.9GPa) > EXB (12.9MPa; 6.7GPa), whereas for n IT, EXB (40 per cent) > EXA (34.9 per cent), TLR (33.6 per cent). All materials were affected by prolonged water storage with significant differences among them in VHN. TLR was the most affected material (ΔVHN = -11 per cent), followed by EXA (ΔVHN = -6.8 per cent) and EXB (ΔVHN = -4.2 per cent). No statistically significant differences were found in the pull-out strength testing (24-24.2 N range) and failure mode (70-77 per cent mixed). Considering the differences between the two experimental materials, it may be concluded that the material containing the PCDMA/UEDMA/TEGDMA co-monomers may be used as an alternative to the control. © The Author 2015.

  4. Long term results of polytetrafluoroethylene in above knee femoropopliteal bypass for critical ischaemia.

    LENUS (Irish Health Repository)

    Kavanagh, E G

    2012-02-03

    Ninety-six consecutive above-knee femoropopliteal bypasses, using polytetrafluoroethylene (PTFE) preferentially, were performed for limb-threatening ischaemia. Cumulative primary graft patency was 68 per cent, 49 per cent and 36 per cent and limb salvage 93 per cent, 85 per cent and 75 per cent at 1, 3 and 5 yr respectively. As a result of poor long term survival (51 per cent at 5 yr), and the healing of remedial lesions before graft occlusion, 68 patients (72 per cent) required no further intervention. Eighteen secondary bypasses were undertaken, 12 using ipsilateral saphenous vein. In this group of elderly patients with poor life expectancy, where a limited operation is desirable, the use of PTFE provided excellent limb salvage with low morbidity. Although we can no longer justify our continued use of PTFE in every case of critical ischaemia because of its inferior patency to autogenous vein, we continue to use it preferentially in patients whose lifespan is likely to be short and in cases where a remedial lesion is present.

  5. Climate change mitigation through energy efficiency : opportunities in Atlantic Canada

    Cote, R.; Archibald, G.

    2008-01-01

    Canada's total energy use is expected to increase by 20 per cent between 2005 and 2020. Studies have suggested that successful energy efficiency initiatives could reduce growth in demand by up to 50 per cent, while reducing greenhouse gases (GHGs) by an estimated 40 per cent. Energy use comprises approximately 65.4 per cent of total expenditures for most businesses. Atlantic region industries contribute nearly 7 per cent of Canadian industrial energy consumption while contributing 5 per cent to the Canadian industrial gross domestic product (GDP). Energy efficiency practices adopted by industry operators in the Maritimes included modifications to boilers, process cooling equipment, motors, compressed air equipment, lighting and HVAC systems. Energy efficiency performance values in the Maritimes range from 11 to 100 per cent, with an average of 65 per cent. Opportunities for improving energy efficiency include inefficient lighting, leaking faucets, poor heat distribution, and inappropriate solid waste segregation. Cost savings for various energy efficiency measures were presented. Case studies of various eco-efficiency programs conducted at plants and businesses in the Maritimes were also included. tabs., figs.

    1976-11-01

    The in vitro protein synthesis by polyribosomes extracted from biopsied muscle (vastus lateralis) was studied in 47 known carriers, 87 possible carriers and in 60 normal females. A significant increase in specific activity of monomeric ribosomes, total polyribosomes and collagen synthesis was found in 46 (97.8 per cent) known carriers and 47 (54 per cent) possible carriers of Duchenne muscular dytrophy. The latter showed an increase in ribosomal protein synthesis in 10 (52.6 per cent) of 19 mothers of isolated cases, 31 (53.3 per cent) of 58 sisters, and 6 (60 per cent) of other female relatives. Serum creatine phosphokinase was increased in 30 (63.8 per cent) of 47 known carriers.

  7. Systematic review of recent evidence for the safety and efficacy of elective endovascular repair in the management of infrarenal abdominal aortic aneurysm.

    2005-08-01

    Conventional management of abdominal aortic aneurysm (AAA) is by open repair and is associated with a mortality rate of 2-6 per cent. Endovascular aneurysm repair (EVAR) is an alternative technique first introduced in 1991. A systematic review was undertaken of the evidence for the safety and efficacy of elective EVAR in the management of asymptomatic infrarenal AAA. Thirteen electronic bibliographical databases were searched, covering biomedical, health-related, science and social science literature. Outcomes were assessed with respect to efficacy (successful deployment, technical success, conversion rates and secondary intervention rates) and safety (30-day mortality rate, procedure morbidity rates and technical issues-endoleaks, graft thrombosis, stenosis and migration). Of 606 reports identified, 61 met the inclusion criteria (three randomized and 15 non-randomized controlled trials, and 43 uncontrolled studies). There were 29 059 participants in total; 19,804 underwent EVAR. Deployment was successful in 97.6 per cent of cases. Technical success (complete aneurysm exclusion) was 81.9 per cent at discharge and 88.8 per cent at 30 days. Secondary intervention to treat endoleak or maintain graft patency was required in 16.2 per cent of patients. Mean stay in the intensive care unit and mean hospital stay were significantly shorter following EVAR. The 30-day mortality rate for EVAR was 1.6 per cent (randomized controlled trials) and 2.0 per cent in nonrandomized trials and case series. Technical complications comprised stent migration (4.0 per cent), graft limb thrombosis (3.9 per cent), endoleak (type I, 6.8 per cent; type II, 10.3 per cent; type III, 4.2 per cent) and access artery injury (4.8 per cent). EVAR is technically effective and safe, with lower short-term morbidity and mortality rates than open surgery. However, there is a need for extended follow-up as the long-term success of EVAR in preventing aneurysm-related deaths is not yet known.

    2004-01-01

    Otolaryngological manifestations of acid reflux include a wide range of pharyngeal and laryngeal symptoms; and the constellation of symptoms has been called laryngopharyngeal reflux. This is a prospective study in a cohort of patients with various throat symptoms suggestive of laryngopharyngeal reflux (LPR) who underwent flexible oesophago-gastroscopy, as a principal investigation. The aims were to look at the most reliable symptom(s) and sign(s), the diagnostic role of flexible oesophago-gastroscopy and the treatment response in these patients. The endoscopy score of 0 to 3 was based on endoscopic findings and the treatment response was measured from 0 to 100 per cent improvement of symptoms, as described by the patients. There were a total of 303 patients, 174 females and 129 males with ages ranging from 19 to 88 years. Seventy-five per cent had had symptoms for more than a year. Fifteen per cent were smokers. Globus, voice change, sore throat, dysphagia and cough were the predominant symptoms. Most patients, however, presented with a complex of various other secondary symptoms. The endoscopic findings were abnormal in 98 per cent of patients. Apart from the finding of non-specific hyperaemia, usually of the posterior larynx (13 per cent), lesions of the larynx and vocal folds were surprisingly uncommon. Proton pump inhibitors (PPI) were prescribed in 90 per cent of patients. A total of 233 (76.8 per cent) responded to treatment. The improvement of symptoms ranged from 25 per cent in 36 (23 per cent), 50 per cent in 60 (20 per cent), 75 per cent in 59 (19 per cent) and 100 per cent in 78 (26 per cent) patients. Accumulative analysis of variance showed a significant difference between treatment responders and non-responders (p <0.04). In a logistic regression model patients with globus, voice change and gastric prolapse were more likely to respond to treatment (p <0.04). It can be concluded that voice change, sore throat, globus and cough choking are the most

    The present work is devoted to the clinical assessment of the Soviet-made cardiac valve prostheses 'EMIKS' and 'LIKS'. From 1983 to May 1, 1988, 632 prostheses were implanted to 508 patients. A group of 348 patients were assessed: 139 after mitral (M) replacement, 130 after aortal (A) replacement, and 79 after mitral-aortal (M+A) replacement. Hospital mortality rate was: in M group--4.3 per cent, in A group--5.3 per cent, in M+A group--8.8 per cent. Survival rate on the fifth postoperative year was: in M group--89.5 +/- 9.2 per cent, in a group--90.0 +/- 4.2 per cent, in M+A group--91.0 +/- 6.2 per cent, the stability of the good results being 85.5 +/- 7.2, 79.5 +/- 6.2, and 75.0 +/- 9.1 per cent, respectively. At year 5 of the follow-up, patient numbers without thromboembolic complications amounted to 95.0 +/- 4.7 per cent in M group, 95.5 +/- 4.2 per cent in A group, and 85.0 +/- 9.1 in M+A group. 95.1 per cent patients belong to functional classes I and II. In mitral replacement, the mean 'EMIKS' gradient was 4.2 +/- 0.58 mm Hg, the 'LIKS' one--4.58 +/- 0.62 mm Hg. Intravascular hemolysis was not observed. The 'EMIKS' and 'LIKS' prostheses match the models produced in other countries. No significant differences between the two models were found.

  12. From development authorities to democratic institutions: Studies in planning and management transition in the Karachi Metropolitan Region

    Full Text Available Karachi is a relatively young metropolis. The city is about three centuries old, founded as a port by local Hindu merchants and traders. The British conquered the city in 1839, occupied the entire principality of Sindh in 1843 and designated Karachi as headquarters of the territory. The city experienced different phases of growth. When Pakistan came into being in 1947, a large number of refugees entered the city and the population jumped from 435,000 in 1947 to 1,050,000 in 1951. Karachi has remained the primate city of Pakistan, with a high annual growth rate of 5-7 percent per annum (Ahmed 1998. Current estimates suggest that the city has about 17 million inhabitants. Karachi houses 7 per cent of the total population and 23 per cent of the urban population of Pakistan. Its current rate of growth is estimated at around 5 per cent, of which 3 per cent is due to natural increase and 2 per cent to migration from the other parts of the country. Karachi provides 25 per cent of federal revenue and 15 per cent of Pakistan’s gross domestic product (GDP. In addition, 50 per cent of the country’s bank deposits and 72 per cent of all issued capital is contributed by the city (Hasan 2010; CDGK 2008. It houses the country’s largest stock market and about 26 per cent of the total national industrial establishments.

    With wide application of antireflux surgery, reoperations for failed fundoplications are increasingly seen. This study was undertaken to document outcomes after reoperative fundoplications. Sixty-four patients, 26 men and 38 women, of average age 55 years+/-15.6 (SD), underwent reoperative antireflux surgery between 1992 and 2003. Fundoplication prior to reoperation had been undertaken via celiotomy in 27 and laparoscopically in 37. Both before and after reoperative antireflux surgery, patients scored their reflux and dysphagia on a Likert Scale (0 = none, 10 = continuous). Reoperation was undertaken because of dysphagia in 16 per cent, recurrent reflux in 52 per cent (median DeMeester Score 52), or both in 27 per cent. Failure leading to reoperation was due to hiatal failure in 28 per cent, wrap failure in 19 per cent, both in 33 per cent, and slipped Nissen fundoplication in 20 per cent. Laparoscopic reoperations were completed in 49 of 54 patients (91%); 15 had reoperations undertaken via celiotomy. Eighty-eight per cent of reoperations were Nissen fundoplications. With reoperation, Dysphagia Scores improved from 9.5+/-0.7 to 2.6+/-2.8, and Reflux Scores improved from 9.1+/-1.4 to 1.8+/-2.7. Seventy-nine per cent of patients with reflux prior to reoperation, 100 per cent with dysphagia, and 74 per cent with both noted excellent or good outcomes after reoperation. We conclude that failure after fundoplication occurs. Reoperations reduce the severity of dysphagia and reflux, thus salvaging excellent and good outcomes in most. Laparoscopic reoperations are generally possible. Reoperative fundoplications are effective treatment for dysphagia and recurrent gastroesophageal reflux, and their application is encouraged.

  16. 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.

  9. Recovery of uranium from Cu-flotation tails

    International Nuclear Information System (INIS)

    Jayaram, K.M.V.; Sankaran, R.N.; Dwivedy, K.K.

    1984-01-01

    Uranium occurs along with copper in several parts of India. Since the total contained uranium in some of these deposits is very large, detailed studies were carried out on samples of ore obtained from Surda, Mosabani and Rakha Cu-flotation tails analysing 0.014 per cent, 0.010 per cent and 0.011 per cent U 3 O 8 and 0.12 per cent 0.09 per cent and 0.11 per cent Cu respectively. Uranium in these samples occurs not only as free uraninite but is also associated with other minerals like apatite, magnetite, tourmaline and micas, formed at different stages of paragenitic sequence. The size also varies considerably. Because of this the recovery of uranium varied from 35 to 70 per cent by wet gravity separation of the feed. Since uranium has to be anyway extracted from these concentrates by hydrometallurgical processing, it is suggested that Cu-flotation tails may be treated by hydrometallurgy to increase the ultimate recovery.

    Mass attenuation coefficients of liquid hydrocarbons and their oxygen, nitrogen and halogen derivates have been measured and compared with the values obtained according to the various calculation instructions (see pt.3). Using the most complete formula according to Schmidt the values obtained are systematically too low (up to 5 per cent), even with best parameter values. Only about half the values deviate by less than 3 per cent. Though the maximum deviations of 5 per cent are beyond the experimental errors (<= +-1 per cent) and the errors introduced by adaption of the general function to the mass attenuation coefficients of elementary absorbers (<= +-2.5 per cent), certain systematic deviation patterns (< 2.5 per cent) can be observed only for individual homologous series (alkanes, benzene derivatives), which may be caused by bonding effects or by remaining shortcomings of the model. The simple formula μsub(Σ) = Σpsub(i)μsub(i) provides effective mass attenuation coefficients, the error of which is up to 10 per cent. (author)

    Boileau, M.A.; Dowling, R.A.; Gonzales, M.; Handel, P.H.; Benson, G.S.; Corriere, J.N. Jr.

    1988-01-01

    We treated 65 patients with prostatic cancer confined clinically to the prostate or periprostatic area during an 8-year period. Seven patients had stage A2, 38 stage B and 20 stage C disease. All 65 patients underwent staging pelvic lymphadenectomy and implantation of gold grains into the prostate (mean dose 3,167 rad). A total of 64 patients then completed a course of external beam irradiation to a mean total tumor dose of 6,965 rad. Complications of therapy were mild and limited (less than 3 months in duration) in most patients, and they included radiation cystitis (32 per cent), diarrhea (31 per cent), extremity lymphedema (7.7 per cent) and wound infection (3 per cent). Two patients suffered urinary incontinence after therapy and 2 (3 per cent) had diarrhea more than 3 months in duration. The actuarial 5-year survival rate for all patients was 87 per cent and the 5-year survival free of disease was 72 per cent

    The clinical features, age at onset and survival of 152 patients with von Hippel-Lindau disease were studied. Mean age at onset was 26.3 years and 97 per cent of patients had presented by aged 60 years. Retinal angioma was the first manifestation in 65 patients (43 per cent), followed by cerebellar haemangioblastoma (n = 60, 39 per cent) and renal cell carcinoma (n = 15, 10 per cent). Overall, 89 patients (59 per cent) developed a cerebellar haemangioblastoma, 89 (59 per cent) a retinal angioma, 43 (28 per cent) renal cell carcinoma, 20 (13 per cent) spinal haemangioblastoma and 11 (7 per cent) a phaeochromocytoma. Renal, pancreatic and epididymal cysts were frequent findings but their exact incidence was not accurately assessed. Mean age at diagnosis of renal cell carcinoma (44.0 +/- 10.9 years) was significantly older than that for cerebellar haemangioblastoma (29.0 +/- 10.0 years) and retinal angioma (25.4 +/- 12.7 years). The probability of a patient with von Hippel-Lindan disease developing a cerebellar haemangioblastoma, retinal angioma or renal cell carcinoma by age 60 years was 0.84, 0.7 and 0.69, respectively. A comprehensive screening protocol for affected patients and at-risk relatives is presented, based on detailed analysis of age at onset data for each of the major complications. Median actuarial survival was 49 years, with renal cell carcinoma the leading cause of death.

  13. Combined gold seed implantation and external radiotherapy for stage B2 or C prostate cancer

    Carey, P.O.; Lippert, M.C.; Constable, W.C.; Jones, D.; Talton, B.M.

    1988-01-01

    Patients with clinical stage B2 or C prostatic carcinoma represent a group for which there are several treatment options. We followed the course and outcome of 72 patients with clinical stages B and C prostate cancer who were treated with surgical staging, insertion of gold grains and external radiation at our institutions between 1975 and 1984. Of the patients 44 (61 per cent) had clinical stage B disease and the majority (89 per cent) of these were stage B2 lesions. The remaining 28 patients (39 per cent) had clinical stage C tumors. In our series 27 per cent of the clinical stage B and 68 per cent of the clinical stage C cancer patients had positive lymph nodes. The 5-year survival free of disease was 52 per cent for patients with both stages of disease. The 7-year survival free of disease was 47 per cent for patients with clinical stage B and 14 per cent for those with clinical stage C cancer. Lymph node status did not have a statistically significant effect on total survival but survival free of disease correlated significantly with node status. Local treatment failures were defined as patients who required transurethral prostatic resection or orchiectomy for palliation of obstructive symptoms related to local tumor regrowth. By these criteria we prevented local progression in 78 per cent of the patients at 5 years

Regarding the consumption profile; the consumers were mostly female (73.4 per cent, age 25–44 (72.8, and educated at tertiary level (74.8 per cent. The majority of respondents perceived that herbal products helped reduce severity of illness and improve health related quality of life, while (16.4 per cent consumed the herbal products for the treatment of menstrual problem, 71.7 per cent without the recommendation of health care professionals and 85.0 per cent of them purchased through over-the-counter retail sales. The herbal products most commonly consume were Labisia pumila (Kacip Fatimah (32.4 per cent, Camellia sinensis (Green Tea (32.1 per cent, Panax ginseng (Ginseng (23.8 per cent, and Eurycoma longifolia (Tongkat Ali (22.5 per cent. Conclusion This study highlights an unhealthy trend in self-prescription of herbal product consumption without healthcare professionals’ recommendation. Hence, there is an urgent need for healthcare professionals to monitor herbal product consumption.

    This paper reports on a qualitative and quantitative analysis of the contents of 4,979 lake trout stomachs (593 examined in 1930 and 1,253 collected in 1931 from southern Lake Michigan, 1,446 from northern Lake Michigan and 1,687 from Green Bay in 1932), and of a total of 1,528 lawyer stomachs (172 examined in 1930 and 734 collected in 1931 from southern Lake Michigan, 612 from northern Lake Michigan and 10 from Green Bay in 1932). The food of the trout consisted of 98 per cent by volume of fish of which Cottidae and Coregonidae were the principal constituents. Cottidae were dominant in southern Lake Michigan (72 per cent by volume), Coregonidae in northern Lake Michigan (51 per cent) but the lake shiner, Notropis atherinides, was most important in Green Bay in the spring of the year (64 per cent). The lawyer food consisted of 74 per cent by volume of fish and 26 per cent invertebrates. Dominant items were Cottidae (76 per cent by volume) in southern Lake Michigan, Coregonidae (51 per cent) and Pontoporeia (37 per cent) in northern Lake Michigan, and Percopsis (34 per cent) and Mysis (26 per cent) in Green Bay. Data are also presented on the frequency of occurrence (number of stomachs) of the food items and its variation with the sizes of the trout and lawyers, depths of water, seasons, and localities; on the number of individual fish of each species destroyed by the trout and lawyers; and on the calculated volume of the food fishes preceding digestion. The lake trout and lawyer are competitors for the same food, are both predators of the commercially important Coregonidae, and the lawyer through its consumption of invertebrates is a food competitor of the Coregonidae.

    Emissions inventories are used by government agencies as a tool for policy development and air quality management. Marine vessels have been identified as a major source of anthropogenic pollution in British Columbia. This report presents estimates of emissions from marine vessels in coastal areas of British Columbia's Fraser Valley Regional District (FVRD) for the year 2000. The project includes an update of emission estimates for each marine vessel category and an update of emission estimates for pollutants of interest, including carbon monoxide (CO), nitrogen oxides (NOx), particulate matter (PM), sulphur oxides (SOx), volatile organic compounds (VOCs), as well as inhalable fine particulates (PM10 and PM2.5) and greenhouse gases such as carbon dioxide, methane, nitrous oxide and ammonia. This report presents both spatial and temporal allocation of emissions. Results indicate that ocean-going vessels are the major contributor to emissions of NOx, SOx, PM and greenhouse gases, accounting for 58, 95, 82, and 58 per cent of the total marine vessel emissions respectively. They also contribute 14 per cent to the marine totals for CO and VOCs. Harbour vessels contribute 28 and 27 per cent of NOx and greenhouse gases and 10 per cent or less to all other contaminant totals. Ferries contribute between 2 per cent and 13 per cent for to each contaminant, including 13 per cent of NOx, 12 per cent of greenhouse gases, and 6 per cent of CO. Fishing vessels contribute 1 per cent or less of all contaminants. Although recreational vessels are major contributors for CO and VOC, they contribute less than 10 per cent for all other contaminants. A comparison of 1993 and 2000 marine vessel inventory for British Columbia was presented and recommendations for improvements were presented. refs., tabs., figs

  18. Important facts on Canada's natural resources (as of November 2004)

    International Nuclear Information System (INIS)

    2004-01-01

    This brochure presents a statistical account of Canada's natural resources sector, including the forest sector, mineral and mining sector, and energy producing sector. Canada's natural resources sectors and allied industries have contributed significantly to the country's economic growth and job creation for several decades. This brochure includes facts for 2003 and information on gross domestic products, direct employment, new capital investment, trade, imports, and balance of trade for each of the 3 sectors. The national economic importance of each sector was also outlined. In 2003, the forest sector contributed $33.7 billion to the Canadian economy (3 per cent of the national gross domestic product). Forest products were a major contributor to Canada's surplus balance of trade in 2003, with major commodities being softwood lumber, newsprint and wood pulp. Canada is also among the largest mining nations in the world, producing more than 60 minerals and metals. In 2003, the value of production from Canadian mining, mineral-processing and metal producing industries was about $50 billion (4 per cent of the national gross domestic product). The brochure includes a table that ranks 2003 world production and exports of uranium, nickel, zinc, gold, copper, potash, asbestos, gypsum and salt. Approximately 80 per cent of Canada's mineral production is exported. The brochure also presents data on the remaining established reserves in 2002 for natural gas (59.8 trillion cubic feet), crude oil (179.1 billion barrels), and primary energy production by commodity. These were 41.5 per cent gas, 32.9 per cent petroleum, 9.5 per cent electricity, 9.0 per cent coal, and 4.0 per cent wood waste. Alberta accounted for 63 per cent of total energy production, followed by British Columbia at 13 per cent, Saskatchewan at 9 per cent, Quebec at 4 per cent, and Ontario at 2 per cent. The international importance of geomatics and geoscience in Canada was also highlighted. This sector

    Full Text Available Background Brucellosis is a common zoonotic disease of the Middle Eastern countries. Acute cases of brucellosis are often treated as cases of Pyrexia of unknown origin. Aims The main aim of this study is to compare the epidemiological, clinical and laboratory findings of the 42 culture positive cases of Brucella. Methods Forty two culture positive cases of Brucella were obtained from both in -patients and outpatients with a history of pyrexia over a period of two years (Nov 2014-Nov 2016. The patients' files were examined retrospectively for the history, clinical features, and lab findings. Results The prevalence of brucellosis was calculated to be 11.1 per cent as 42 cases were positive for brucellosis out of 377 of PUO cases Of the 42 cultures positive patients the percentage of males (57.1 per cent were almost equal to the females(42.8 per cent. The mean±S.D age was 28.5±13.65. 28.5 per cent had a history of livestock associations (Chi-square 3.8889, a p-value of 0.048607 which was statistically significant. 26.2 per cent had a history of raw milk and dairy produce intake (Chi-Square 2.6276, p-value of 0.105023 this was not statistically significant. 9.5 per cent had a family history of brucellosis; this association was not statistically significant as well (chi-square statistic 1.8651, p-value of 0.172034. 61.9 per cent presented as acute cases, 30.9 per cent of sub-acute cases and 7.1 per cent as chronic cases respectively. The pre- dominant clinical symptom was Fever (100 per cent with the commonest clinical signs being the osteoarticular signs (30.9 per cent. Raised ESR and CRP positives were seen in 34 cases (80.9 per cent and 23 cases (55 per cent respectively followed by Anaemia in 22 cases (52.3 per cent. Forty two cases were blood culture positive. All the cases were sensitive to the recommended regimen of Doxycycline and streptomycin. Conclusion Brucellosis is still a major health problem in the Middle Eastern countries especially

    Dental disease is now recognised as a major but often unrecognised disorder of equids, including horses and donkeys. However, very few large clinical studies have documented the prevalence and type of dental disease present in different equid populations and no dental studies have been reported in Zamorano-Leonés or Mirandês donkeys, two endangered donkey breeds. Clinical and detailed oral examinations were performed in 400 Mirandês and 400 Zamorano-Leonés donkeys in Portugal and Spain. It was found that just 4.5 per cent had ever received any previous dental care. Cheek teeth (CT) disorders were present in 82.8 per cent of these donkeys, ranging from a prevalence of 29.6 per cent in the 25-year-old group. These CT disorders included enamel overgrowths (73.1 per cent prevalence but with just 6.3 per cent having associated soft tissue injuries), focal overgrowths (37.3 per cent), periodontal disease (23.5 per cent) and diastemata (19.9 per cent). Peripheral caries was present in 5.9 per cent of cases, but inexplicably, infundibular caries was very rare (1.3 per cent prevalence); this may have been due to their almost fully foraged diet. The high prevalence of enamel overgrowths in these donkeys, most which never received concentrates, also raises questions about the aetiology of this disorder. This very high prevalence of CT disorders, especially in older donkeys, was of great welfare concern in some cases and emphasises the need for routine dental care in these cases on welfare grounds and in order to help preserve these unique breeds.

  3. Electricity supply, district heating and supply of natural and gasworks gas 1999

    International Nuclear Information System (INIS)

    2001-01-01

    Total domestic use of electricity (including transmission losses) was 143.3 TWh in 1999. This represents a decrease of 0.5 per cent compared to 1998. Usage in the household sector fell by 1.5 per cent to 34.3 TWh (including second homes). In contrast, the industry sector (manufacturing industry, mining and quarrying) increased its usage by 1.1 per cent to 55.3 TWh. Deliveries of steam and hot water for district heating were 43.7 TWh, unchanged compared to 1998. Total net production of electricity decreased in 1999 by 2.5 per cent compared to 1998 and amounted to 150.8 TWh. Hydroelectric production decreased by 4.0 per cent to 70.9 TWh. The production of conventional thermal power also fell, by 5.6 per cent to 9.4 TWh. Nuclear power contributed 70.2 TWh, almost the same as the previous year. Wind power, however, increased its production by 16.2 per cent to 358 GWh. Imports of electricity increased by 0.4 TWh to 8.5 TWh, but exports decreased by 0.9 TWh to 15.9 TWh. Total deliveries of natural gas to final consumers diminished somewhat in 1999 and amounted to 854 million m 3 (equivalent to 9226 GWh). Deliveries of natural gas substitutes (air/liquefied petroleum gas mix) decreased by 5 per cent to 26 million m 3 . The mean price of natural gas rose by approximately 6 per cent compared to 1998. Deliveries of gas-works gas fell in 1999 by 0.6 million m 3 to 109.2 million m 3 . The mean price was about 11 per cent higher than in the preceding year

    Health literacy on tuberculosis (TB) is an understanding about TB to perform activities with regard to prevention, diagnosis and treatment. We undertook a study to assess the health literacy on TB among one of the vulnerable tribal groups (Saharia) in central India. In this cross-sectional study, 2721 individuals aged >15 yr from two districts of Madhya Pradesh State of India were interviewed at their residence during December 2012-July 2013. By using a short-form questionnaire, health literacy on cause, symptoms, mode of transmission, diagnosis, treatment and prevention of TB was assessed. Of the 2721 (Gwalior 1381; Shivpuri 1340) individuals interviewed; 76 per cent were aged literacy rate was 19 per cent, and 22 per cent had >7 members in a house. Of the 2721 respondents participated, 52 per cent had never heard of TB; among them 8 per cent mentioned cough as a symptom, 64 per cent mentioned coughing up blood, and 91 per cent knew that TB diagnosis, and treatment facilities were available in both government and private hospitals. Health literacy score among participants who had heard of TB was 60 per cent among 8 per cent of respondents. The finding that nearly half of the respondents had not heard of TB indicated an important gap in education regarding TB in this vulnerable population. There is an urgent need to implement targeted interventions to educate this group for better TB control.

    Full Text Available The Spanish economy was hit hard by the late 2007 collapse of a speculative housing boom as well as by the global financial crisis. The economy formally went into recession in 2009 as Spain’s pre-crisis budget surplus of 3 per cent of GDP became a deficit of 11.1 per cent. Spain posted -0.1 per cent growth in 2010 and 0.7 per cent growth in 2011. The economy once again entered recession in 2012, with only modest prospects for recovery forecast for 2013 and 2014. Unemployment has soared to over 25 per cent, and is not expected to decrease significantly in the next few years. Youth unemployment has reached over 50 per cent. Responding to the crisis, the Government embarked in 2010 on a substantial program of reforms and austerity measures aimed at correcting imbalances in the economy and encouraging recovery, improving public finances. These efforts have intensified. Eurozone finance ministers (the ‚Eurogroup’ have set the government a budget deficit target of 6.5 per cent of GDP for 2013 and 5.8 per cent in 2014, falling to the desired target of under 3 per cent by 2016. The Eurogroup has also provided a euro 100bn line of credit to recapitalise Spain’s banking sector. Successive austerity measures, which have become the subject of popular protests, aim to cut the deficit through spending reductions to public administration.

    According to a survey conducted by the Ziff Energy Group, industry insiders are optimistic about natural gas supply and demand during 2000. The survey, which was designed to provide an integrated description of the North American gas industry from wellhead to burner tip, covered 124 companies across North America. Slightly more than half of the U.S. respondents expect to produce at least five per cent more natural gas in 2000 than the previous year, while 19 per cent of the respondents expect production increases to exceed 15 per cent. Among Canadian respondents, some 70 per cent expect production to increase five per cent; another 25 per cent anticipate increases in production to reach or exceed 15 per cent. Canadian natural gas export to the United States are expected to grow by up to 700 million cubic feet per day by almost 50 per cent of Canadian respondents; one third of the respondents expect exports to increase by 700 to 900 million cubic feet per day. Growth in U.S. demand for natural gas are predicted to be moderate in 2000, and increase somewhat in 2001. Canadian growth in sales is expected to be in the one-to-two per cent range. Few of the respondents expect gas prices to decline, and few are concerned that gas prices may put sales at risk. The majority of respondents believe that gas supply growth poses the greatest challenge to increasing pipeline capacity

    Results of radium therapy with or without multi-disciplinary treatment for carcinoma of the tongue were studied in 117 patients treated from 1973 to 1981 at Gunma Cancer Center. 1. The patients were classified according to the TNM classification of UICC (1978). Seventeen patients were T1, 42 were T2, 31 were T3, 27 were T4, 92 were NO, 18 were N1, 2 were N2 and 5 were N3. 2. The treatment methods included external irradiation with 1,000-2,000 rads by 6MV X-ray followed by radium interstitial implants of 6,000-8,000 rads in 93 patients (73.9 per cent), radium therapy with additional Bleomycin 45-60 mg in 24 patients (20.5 per cent), and cryosurgery in 3 patients. 3. The five year survival rate was 41.6 per cent; 100.0 per cent for T1, 50.0 per cent for T2, 38.8 per cent for T3 and 10.5 per cent for T4. The overall five-year cumulative survival rate was 46.9 per cent. For primary lesions of T3 or T4, greater efforts should be made with combined modalities, such as planned multi-disciplinary treatments with combined radiation and major surgery. (author)

    To describe the concomitant imaging and genetic findings in children diagnosed with non-syndromic unilateral sensorineural hearing loss. A retrospective cohort study was conducted of 60 children diagnosed between January 2005 and December 2015 in a tertiary-level paediatric institution. Average age at diagnosis was 4.3 years. All children were considered non-syndromic. Hearing loss was categorised as mild (17 children), moderate (17 children), severe (7 children) or profound (19 children). Imaging was performed in 43 children (71.66 per cent). Nineteen patients (44.2 per cent) had positive computed tomography or magnetic resonance imaging findings. Genetic testing was performed in 51 children (85 per cent). Sixteen children (31 per cent) tested positive to connexin 26 (GJB2); 1 patient (2 per cent) had a homozygous mutation of GJB2 and 15 were heterozygous carriers. Amongst children who tested positive as heterozygous carriers of a GJB2 mutation, there was a high rate of positive imaging findings (47 per cent compared to 37.2 per cent in the total cohort). A genetic abnormality was confirmed in 50 per cent of children with positive imaging findings who underwent genetic testing. Rates of concomitant imaging and genetic findings suggest that both investigations are of value in the study of these patients.

    The stable isotope 15 N was used to study the fate of nitrogen fertilizers applied to a black earth growing wheat. In a glasshouse experiment using soil packed at 56 per cent moisture (pF 2) into pots, added nitrate was almost completely recovered (mean, 98.8 +- 2.3 per cent) by soil and plant analysis. This experiment was repeated using 15 N-labelled ammonium as well as nitrate; mean recoveries at 15 weeks were 96.8 and 97 per cent respectively (+- 2.2 per cent at P 15 N measured, 97 and 96.8 per cent at 56 and 63 per cent moisture respectively. Fallow and planted systems were then studied in a gas lysimeter. During experiments lasting up to 14 weeks, gaseous losses as 15 N-labelled denitrification products were less than the equivalent of 0.2 μg nitrogen/g soil (the lower limit of detection with a mass spectrometer). Although analysis of plant and soil from the lysimeter in two experiments showed virtually quantitative recovery (99.7 and 97.05 per cent), small (0.16 per cent) losses of labelled ammonia into the lysimeter atmosphere were detected. The significance of these results is discussed in relation to the common finding of large deficits in nitrogen balance studies. (author)

    Full Text Available Abstract Background To evaluate medical and dental students' utilization of electronic information resources. Methods A web survey sent to 837 students (49.9% responded. Results Twenty-four per cent of medical students and ninteen per cent of dental students searched MEDLINE 2+ times/month for study purposes, and thiry-two per cent and twenty-four per cent respectively for research. Full-text articles were used 2+ times/month by thirty-three per cent of medical and ten per cent of dental students. Twelve per cent of respondents never utilized either MEDLINE or full-text articles. In multivariate models, the information-searching skills among students were significantly associated with use of MEDLINE and full-text articles. Conclusion Use of electronic resources differs among students. Forty percent were non-users of full-text articles. Information-searching skills are correlated with the use of electronic resources, but the level of basic PC skills plays not a major role in using these resources. The student data shows that adequate training in information-searching skills will increase the use of electronic information resources.

    The antimicrobial effect of nisin (at 1000UI/g), and irradiation (at 1, 3 and 5kGy), against the growth of Salmonella enteritidis (106 ufc/ml) and Bacillus Stearothermophilus (10 6 ufc/ml), inoculated in turkey salami, was studied during storage at 4 degree for 21 days. Treatment of turkey salami with nisin at 1000UI/g did not show any antimicrobial activity against S. Enteritidis with 6.7 pour cent and 0.8 pour cent of reduction after 0 and 21 days of storage respectively, and seems to be insufficient to inhibit B. Stearothermophilus with 23 pour cent and 21 pour cent of reduction after 0 and 21 days of storage respectively. Antimicrobial activities of irradiation were better and proportional to irradiation doses; it shows a reduction of 27 pour cent, 55 pour cent and 67 pour cent by D1, D2 and D3 respectively. The combination of nisin with irradiation at 5kGy showed stronger antimicrobial activities than those obtained by its combination with the first and the second irradiation dose.

    Polymerase chain reaction was utilized to characterize the VP4 types of 39 Rotavirus field isolates from symptomatically infected children in Nigeria. Genotype P6 was identified most frequently, occurring in 41.03 per cent of the typed specimens. Genotype P8 was identified as the next most prevalent (33.3% per cent). Genotype p6 was widespread (68.75 per cent) among infected neonates in Southern Nigeria, but mix infection was more prevalent (70 per cent) among Northern Nigerian children. Four distinct strains were identified with four different P genotypes. Overall strain G1P8 predominated (22.22 per cent) followed by G3P6 (17.8 per cent). Strain G1P8 was most prevalent (70 per cent) among infants aged 3.1-9 months, but strain G3P6 was most frequently identified among neonates occurance of mix infection genotype demonstrates the potential for reassortment events among different rotavirus genogroups in Nigeria. The epidemiological implications of these findings for rotavirus vaccine development and application in the country were discussed.

    A retrospective analysis of 47 patients with suspected bone metastases is performed to evaluate the role of bone scan in diagnosis or treatment and to compare radionuclide images with radiographs. Scan revealed solitary lesions in 27.7 per cent, multiple lesions in 44.7 per cent and was normal in 10.6 per cent of patients studied. In 11 patients the scan was +ve and x-ray was -ve and scan was false negative in one patient. Role of bone scan is evaluated by a scoring method. Scan contributed to correct diagnosis in 25.5 per cent, altered the management in 21.3 per cent of patients. However, scan by itself did not contribute to final management in 48.6 per cent of patients. Scan had misled the diagnosis because of false positive result in 4.3 per cent of patients. It is highlighted that though bone scan is non-specific, it has contributed considerably to the management of majority of patients. (author). 10 refs., 3 tabs., 4 figs

    Full Text Available This paper is based on an empirical study of five foreign MNC BPO firms operating in India, ranked among the top 100 by the International Association of Outsourcing Professionals (IAOP for the year 2009. The data was collected using quantitative methods from 163 employees constituting 1% of the population under study. The level of satisfaction among the respondents towards the performance appraisal system is at 69.94 per cent. Regression analysis, using a significance level of 5 per cent, shows that three of the variables used in the study are significantly influencing the satisfaction and all these three significant variables are positively associated with satisfaction and all other variables have emerged as the insignificant variables. All the variables used in our study collectively account for 42.6 per cent of the satisfaction. The factor analysis has identified four factors: the variables of factor one contribute 34.786 per cent variation, followed by 12.788 per cent, 11.961 per cent and 8.389 per cent variation being contributed by factor two, three and four respectively.

    One hundred and seventy-three underwent proximal gastric vagotomy for duodenal ulceration over a 6-year period. One hundred and fifteen of these have been followed up for 1-5 years. The operative mortality was nil and the result was satisfactory in 91 per cent. The incidence of side effects was small, notably that of dumping being 2.4 per cent and of diarrhoea, 3.6 per cent. Incidence of postoperative heartburn was reduced from 13 per cent to 4 per cent by the introduction of hepatic interposition. The incidence of recurrent ulceration was 5.1 per cent after an average interval of 2 years and that of new gastric ulceration 2.6 per cent after an average of 4 years. There were no recurrent ulcers in those who had peroperative Burge tests, although secretory studies showed no difference between those tested and those not tested. Most recurrences occurred in the earliest cases operated on before Burge testing was introduced and when only 2 cm of the lower oesophagus were exposed.

    Using the Reinhart-Rogoff dataset, we find a debt threshold not around 90 per cent but around 30 per cent, above which the median real gross domestic product (GDP) growth falls abruptly. Our work is the first to formally test for threshold effects in the relationship between public debt and median real GDP growth. The null hypothesis of no threshold effect is rejected at the 5 per cent significance level for most cases. While we find no evidence of a threshold around 90 per cent, our findings from the post-war sample suggest that the debt threshold for economic growth may exist around a relatively small debt-to-GDP ratio of 30 per cent. Furthermore, countries with debt-to-GDP ratios above 30 per cent have GDP growth that is 1 percentage point lower at the median.

    Full Text Available The article is about the phenomenon of corruption in a comprehensive school. It analyses the expression forms of corruption and their peculiarities and disputes the main reasons stimulating educators to take part in corrupt interchanges thus tolerate it. On the ground of empirical research in Vilnius secondary schools it discloses attitudes of teachers, schoolchildren and parents towards corruption. The research was carried out in Vilnius Salomėja Nėris gymnasium, Vilnius Mikalojus Daukša secondary school, Mindaugas secondary school, Užupys gymnasium, Antakalnis gymnasium, Naujamiestis secondary school and Stanevičius secondary school. Overall 500 respondents were questioned: 300 pupils of ninth – twelfth forms, 100 teachers and 100 parents of schoolchildren. Difficult financial circumstances were pointed out as the main reason stimulating teachers to take part in corrupt interchanges. This answer was chosen by 42 per cent of respondents. Most of them think that raising wages would reduce corruption crimes. The research data show it is an important problem in schools though 70 per cent of respondents state it is not the biggest problem in their school. Only 15 per cent of questioned schoolchildren, 4 per cent of parents and 14 percent of teachers safely state that corruption is the main problem in their school. About 20 per cent of respondents (21.4 per cent of schoolchildren, 19 per cent of parents and 21 per cent of teachers acknowledge of making a payoff or receiving an offer to take it. Respondents state that 30 per cent of their friends and relatives made a payoff to school staff. 26.7 percent of schoolchildren and 27 per cent of parents’ acquaintances made a payoff to school staff. Only the answers of teachers did not change – 21 per cent of their colleagues were offered a payoff. These results do not let affirm that corruption is very widely spread in schools and therefore could be named as the biggest problem here. Though

    There is paucity of data on the inter-observer agreement and diagnostic accuracy between a primary-care technician (vision technician) and an ophthalmologist. Hence, the current study was conducted to assess the accuracy of vision technicians, to screen potentially sight-threatening ocular conditions at rural vision centres of southern India and their agreement with an ophthalmologist. In July to August 2010, patients presenting to seven vision centres in Adilabad district (Andhra Pradesh) were selected and screened in a masked manner by seven vision technicians followed by an examination by a consultant ophthalmologist. Agreement was assessed between vision technicians and the ophthalmologist for screening of potential sight-threatening ocular conditions and decisions for referral. The ophthalmologist's findings were considered as the reference standard. Two hundred and seventy-nine patients were enrolled at seven vision centres with a mean age of 32.9 ± 21.8 years. Agreement for screening of ocular pathology was 0.82 (95 per cent CI, 0.8-0.83). There was excellent agreement for cataract (0.97; 95 per cent CI, 0.93-1), refractive error (0.98; 95 per cent CI, 0.96-1), corneal pathology (1.0; 95 per cent CI, 1.0-1.0) and other anterior segment pathology (0.95; 95 per cent CI, 0.9-1); the agreement was moderate to fair for detection of glaucoma suspects (0.43; 95 per cent CI, 0.28-0.60) and retinal pathology (0.39; 95 per cent CI, 0.14-0.63). Sensitivity for screening of anterior segment pathology was 94.6-100 per cent. There was a fair to moderate sensitivity for glaucoma suspect; 35.6 per cent (95 per cent CI, 21.9-51.2) and retinal pathology 26.3 per cent (95 per cent CI, 9.2-51.2). Specificity for screening of ocular pathology was 98.2 to 100 per cent. The kappa (κ) agreement for referral for any pathology was 0.82 (0.8-0.83) CONCLUSION: As there is good agreement between the vision technicians and the ophthalmologist for screening and referral of

    Gross electricity production in 1993 in the OECD (including generation from pumped storage plants) was 7 466 TWh, a rise of 1.2 per cent from the level of gross production in 1992 (Tables 1 and 3). Nuclear plants accounted for 24.2 per cent of total gross electricity production in 1993, hydroelectric plants 16.7 per cent, total thermal plants 58.7 per cent and geothermal and other renewables 0.4 per cent. In 1992 total OECD heat production that is sold to third parties by public producers was 25 Mtoe (Table 6). About 86 per cent of this heat (21.6 Mtoe) was produced in CHP plants, about 12 per cent (3.1 Mtoe) in heat plants, and the remainder (0.3 Mtoe) in nuclear power plants (in Canada and Switzerland only). Based on preliminary data, apparent consumption of electricity (gross production plus imports less exports) in 1993 in OECD was 7 474 TWh. The corresponding figure for 1992 was 7 379 TWh, indicating a rise of 1.3 per cent in apparent electricity consumption in OECD countries in 1993. OECD countries imported a total of 219 TWh of electricity in 1993 (including from other OECD countries) and exported 211 TWh (including to other OECD countries). Accordingly, net imports of electricity in 1993 amounted to 7.7 TWh. Real electricity prices (as measured by the indices of real energy prices) in the OECD fell slightly in 1993 from 1992 levels for both industry and household end-users (Table 20). Electricity prices for industrial consumers vary widely across OECD countries. Based on data that are available for 1993, prices varied from 3.3 US cents per kWh in New Zealand to 12.1 US cents per kWh in Portugal. Electricity prices for industry are reported in Tables 24 and 25. Electricity prices for domestic consumers also vary widely across OECD countries. Based on data that are available for 1993, prices varied from 5.8 US cents per kWh in New Zealand to 18.0 US cents per kWh in Denmark (Tables 26 and 27)

    The 2004 reporting to the ISAG comprises 394 plants owned by 256 enterprises. In 2003, reports covered 403 plants owned by 273 enterprises. Waste generation in 2004 is compared to targets for 2008 in the government's Waste Strategy 2005-2008. The following summarises waste generation in 2004: 1) In 2004, total reported waste arisings amounted to 13,359,000 tonnes, which is 745,000 tonnes, or 6 per cent, more than in 2003. 2) If amounts of residues from coal-fired power plants are excluded from statistics, waste arisings in 2004 were 12,179,000 tonnes, which is a 9 per cent increase from 2003. 3) If amounts of residues from coal-fired power plants and waste from the building and construction sector are excluded from statistics, total waste generation in 2004 amounted to 7,684,000 tonnes, which is 328,000 tonnes, or 4 per cent, more than in 2002. In other words, there has been an increase in total waste arisings, if residues and waste from building and construction are excluded. Waste from the building and construction sector is more sensitive to economic change than most other waste. 4) The total rate of recycling was 65 per cent. The 2008 target for recycling is 65 per cent. The rate of recycling in 2003 was also 65 per cent. 5) The total amount of waste led to incineration amounted to 26 per cent, plus an additional 1 per cent left in temporary storage to be incinerated at a later time. The 2008 target for incineration is 26 per cent. These are the same percentage figures as applied to incineration and storage in 2003. 6) The total amount of waste led to landfills amounted to 8 per cent, which is one percentage point better than the overall landfill target of a maximum of 9 per cent landfilling in 2008.

    Full Text Available Background Interns, or first year junior doctors, have traditionally been used as an adaptable frontline solution to many of the changes in healthcare, utilising their broad skill sets for both direct patient care and administrative burdens. While there are studies that focus on the total hours junior doctors work, there are few that analyse the specific tasks they do and how they dedicate their work time. Aims We aim to quantify the amount of time intern doctors spent on specific tasks during a shift. Methods This is a multi-centred, retrospective, self-reported study that was carried out in a public tertiary hospital network in Western Australia, comprising one tertiary, two metropolitan, and three regional hospitals. 68 individual shifts were reported, accounting for 605.72 hours. Participants reported time spent, in fifteen minute segments, on categories grossly defined as clerical tasks, clinical tasks, teaching, and personal time. Participants were also asked about their satisfaction with the amount of clinical exposure during the reported shift. Results Direct patient care accounted for 22 per cent of total shift time, indirect care 74 per cent, and personal time 4 per cent. Discharge summaries accounted for the most time-per-shift at 26 per cent, followed by medical note documentation at 14 per cent, with the least being teaching at 2 per cent. Direct patient contact by interns during a shift was on average 12 per cent (SD 14 per cent. 12 interns or 18 per cent of all responses reported no direct patient contact (0 per cent during a shift. Interns working in emergency medicine spent 44 per cent of their shift on direct patient contact, significantly more compared to their medicine and surgical colleagues. Conclusion Indirect care activities consume almost three times as much time as direct care activities. Interns are mostly unsatisfied with their amount of clinical exposure per shift. The results concur with the current literature of

    The records of all patients treated for thymoma in the Department of Radiotherapy of Torino University between 1970 and 1988 were reviewed. There were 59 in stage 3 and 18 in stage 4a; 74 patients were operated before radiotherapy and 3 had a pre-operative irradiation followed by surgery and post-operative boost. Complete resection was possible in 55.9 per cent of stage 3 cases and in none with stage 4a. Subtotal resection was done in 36.6 per cent of stage 3 patients and 83.3 per cent in stage 4a. 8 patients had only biopsy: 5 in stage 3 (8.5 per cent) and 3 in stage 4a (16.6 per cent). Post-operative radiation doses ranged between 39.6 and 46 Gy to the whole mediastinum followed by a 10-16 Gy boost on smaller fields in cases presenting residual disease after surgery. The pre-operative dose was 30 Gy followed by a post-operative boost of 16-24 Gy. Conventional fraction sizes of 1.8-2 Gy were always used. The 10 years survival rate was 58.3 per cent. There was a significant difference between stage 3 (70.9 per cent) and stage 4a (26.3 per cent)(p<0.0004). Survival of patients in stage 3 was not significantly affected by the type of surgery. No significant difference in survival or recurrence rate was observed in patients with different histologies and in patients with or without myasthenia. Thoracic relapses occurred in 15. 2 per cent of stage 3 patients and in 50 per cent of stage 4a patients (p<0.01). Only 7 relapses (9.1 per cent) were within the limits of the radiation field. Radiotherapy seems to be effective in reducing the risk of local recurrence and prolonging survival in patients operated upon for locally advanced thymoma. More patients are alive and free of disease at 10 years than those who received radical surgery. (author). 26 refs.; 4 figs.; 5 tabs

    We present optical identifications for 66 IRAS point sources in the region of the Fornax cluster of galaxies, 106 IRAS point sources in the region of the Hydra I cluster of galaxies (Abell 1060) and 59 IRAS point sources in the region of the Coma cluster of galaxies (Abell 1656). Eight other sources in Hydra I do not have optical counterparts and are very probably due to infrared cirrus. Twenty-three (35 per cent) of the Fornax sources are associated with stars and 43 (65 per cent) with galaxies; 48 (42 per cent) of the Hydra I sources are associated with stars and 58 (51 per cent) with galaxies; 18 (31 per cent) of the Coma sources are associated with stars and 41 (69 per cent) with galaxies. The stellar and infrared cirrus surface density is consistent with the galactic latitude of each field. (author)

    Exposure to high levels of environmental tobacco smoke can occur in hotels. Controversy exists about smoking regulation on licensed premises. This survey of 138 people attending one of three Newcastle hotels during 1993 found that 57 per cent of respondents were nonsmokers. Fifty-eight per cent (95 per cent confidence interval (CI) 50 to 66 per cent) of respondents in these hotels believed their health was being adversely affected by other people's smoke in the hotel. Seventy per cent (CI 62 to 78 per cent), including half the smokers, were in favour of restriction of smoking in the hotels. Most preferred the establishment of smoke-free areas to the introduction of total smoking bans in hotels. The failure of hotels to regulate smoking suggests that a legislative approach is required. The case for legislation would be strengthened by a larger study elsewhere in Australia.

    Some researchers have suggested that qualitative research is increasing in the gerontology field, but little systematic analysis has tested this assertion. Using the Canadian Journal on Aging/La Revue canadienne du vieillissement as a case study, we analysed articles reporting on original research from 1995 to 2012. One in four articles were qualitative, and results in three-year intervals show a clear increase in qualitative research findings during this 18-year time frame: (a) 1995-1997: 10 per cent; (b) 1998-2000: 19 per cent; (c) 2001-2003: 25 per cent; (d) 2004-2006: 25 per cent; (e) 2007-2009: 29 per cent; and (f) 2010-2012: 43 per cent. In all time intervals (with the exception of 2004-2006), French language articles were more likely to use a qualitative research design compared to English language articles. Topics, methodologies, and data collection strategies are also discussed.

    In Australia workers in many industries are required to wear safety footwear (footwear incorporating a steel toe cap). An investigation of the problems reported by 321 workers (70 per cent male) employed in a broad range of work activities and required to wear safety footwear was conducted in 1990 and 1991. Respondents were interviewed by a professionally trained podiatrist using a structured questionnaire followed by a foot examination. An extremely high percentage (91 per cent) of subjects reported one or more foot problems (which were verified by the podiatrist), and most considered that the safety footwear either caused the problem or adversely affected an existing foot condition. The main shoe concerns reported were excessive heat (65 per cent of all respondents), inflexible soles (52 per cent), weight (48 per cent) and pressure from steel toe cap (47 per cent). Certain gender differences were identified. General recommendations are made.

    Different NiMo catalysts supported on titania modified Al{sub 2}O{sub 3} were synthesized and characterized in an effort to study the hydrodenitrigenation (HDN) and hydrodesulfurization (HDS) of different gas oils derived from Athabasca bitumen. The Al{sub x}O{sub 3} supports were modified by incorporating up to 9 wt per cent titanium (Ti). All modified supports as well as fresh and spent catalysts were characterized by BET surface area, pore volume and pore diameter, XRD, TPR, TPD and SEM. A trickle-bed reactor using 3 different gas oils from the Athabasca bitumen was used to test the initial activity of these catalysts. The 3 oils were light gas oil (LGO), heavy gas oil (HGO) and blended gas oil having 50 per cent LGO and 50 per cent HGO. The study showed that nitrogen conversion increased for all the gas oils when Ti was incorporated into the alumina. With an increase in Ti concentrations from 0 to 6 wt per cent, nitrogen conversion increased from 57-69.5 wt per cent, 75-80.2 wt per cent, 83-91.5 wt per cent and for LGO, HGO and blended, respectively. Nearly 86 wt per cent sulphur conversion was obtained for all Ti concentrations for LGO, while HGO and blended sulphur conversions were in the range of 96-97 wt per cent. Detailed hydrotreating and hydrocracking of HGO was then performed using the 6 wt per cent Ti modified catalyst because it achieved the maximum nitrogen conversion. This paper also presented the temperature, pressure and liquid hourly space velocity for this catalyst along with the maximum nitrogen and sulphur conversions. Results were compared with those of commercial catalysts. tabs., figs.

    With the emergence of metallo-betalactamases (MBL) in Pseudomonas aeruginosa (P. aeruginosa), the value of carbapenem, the drug of last resort, is being severely compromised. Curtailing the use of carbapenems becomes paramount if resistance is to be reined in. To study the role of synergy between combinations of drugs as an alternative treatment choice for P. aeruginosa. Synergy was studied between combinations of levofloxacin with piperacillin-tazobactam and levofloxacin with cefoperazone-sulbactam by time-kill and chequerboard techniques. P. aeruginosa were tested for antibiotic susceptibility by the disc diffusion assay (260 isolates) and E-test (60 isolates). Synergy testing by chequerboard and time-kill assays was performed with combinations of piperacillin-tazobactam with levofloxacin (11 isolates) and cefoperazone-sulbactam with levofloxacin (10 isolates). Nearly all isolates were susceptible to piperacillin-tazobactam (96.1 per cent), followed by piperacillin (78.5 per cent). Seventy-one isolates (27.3 per cent) were found to be multidrug resistant and 19.6 per cent were ESBL producers. MIC50 of amikacin was 32μg/ml and MIC90 was 64μg/ml. MIC50 and MIC90 of cefoperazone-sulbactam was 32μg/ml and 64μg/ml, and for levofloxacin it was 10μg/ml and 240μg/ml, respectively. Piperacillin-tazobactam had MIC50 and MIC90 of 5μg/ml and 10μg/ml, respectively. Synergy was noted in 72.7 per cent isolates for levofloxacin and piperacillin-tazobactam combination, the remaining 27.3 per cent isolates showed addition by both chequerboard and time-kill assay. For levofloxacin and cefoperazone-sulbactam, only 30 per cent isolates had synergy, 40 per cent showed addition, 20 per cent indifference, and 10 per cent were antagonistic by the chequerboard method. The combination of levofloxacin and piperacillin-tazobactam is a good choice for treatment of such strains.

    British Asians represent a substantial proportion of the population in some parts of the United Kingdom, yet many fail to use dental services regularly. This study aimed to investigate dentists' concerns about providing care for this client group. Following a pilot study, a postal questionnaire was sent to general dental practitioners and community dental officers working in seven family health services authority localities. Of 1546 questionnaires circulated, 639 (41 per cent) were returned. The language barrier was most frequently identified as a major impediment to care (78 per cent), followed by patients' understanding of treatment proposed (67 per cent), while 64 per cent found difficulty obtaining medical histories. Only 20 per cent considered that gaining consent for treatment was a problem. Other issues concerned attendance as casual patients (65 per cent) and, in terms of treatment provided, difficulties with preventive (77 per cent), periodontal (66 per cent) and orthodontic care (27 per cent). The proportion of dentists identifying barriers to care reflected the English-speaking abilities of different Asian populations. Compared with the high percentage mentioning language, understanding and medical history, the small proportion of dentists who thought that consent was of concern suggests that concepts of consent may need to be questioned. Despite the low response rate, the high proportion of respondents identifying these issues implies that the present position may put patients' health at risk, restrict treatment options and offer a potential for litigation. Future initiatives to overcome barriers to appropriate care must address the perspectives of dentists treating British Asians, as well as that of the client group.

    This report reviewed energy efficiency strategies in Canada's economic sector, and provided information on the contributions made by various energy efficiency initiatives administered by Natural Resources Canada through its Office of Energy Efficiency. Energy use in Canada increased by 22 per cent between 1990 and 2003, in contrast to the 32 per cent anticipated without energy efficiency increases. Energy-related greenhouse gas (GHG) emissions were 52 megatonnes lower than they would have been without energy efficiency programs, indicating that strong and measurable progress has been made. In the residential sector, the combined effects of a 26 per cent increase in activity, an increase in energy demand due to weather, and an increase in the average number of appliances per household were partly offset by a 19 per cent improvement in energy efficiency. A 45 per cent increase in industrial activity along with a 13 per cent improvement in energy efficiency between 1990-2003 was noted. A 15 per cent increase in passenger transportation and a 40 per cent increase in freight transportation were offset by a 16 per cent improvement in energy efficiency. Basic policy instruments were reviewed, as well as information and voluntary programs, direct financial incentives, and various regulations to eliminate less efficient products from the market. It was noted that the Green Municipal Fund has recently provided over $248 million to support 419 feasibility studies and energy efficiency projects. The federal budget has provided an additional $300 million towards the fund. 22 figs.

    Natural immunity to the causative agent of hemorrhagic fever with renal syndrome (HFRS) has first been studied using radioimmunoassay (RIA) in the human population of the Bashkir ASSR with the highest incidence of this infection and of five other regions of the RSFSR with lower incidence of HFRS. The antigen was prepared as a suspension of lungs of rodent from natural HFRS foci and contained a high concentration of virus protein. 12000 sera from the population of 6 areas of the RSFSR were examined. In the Bashkir ASSR antibodies were detected in 13.7 per cent of the subjects examined, this figure varying in different districts from 4.0 to 41.5 per cent. In the other areas the portion of immune subjects varied from 6.7 per cent in Kuybyshev region to 1.6 per cent in Vladimir region. No correlation between the size of the immune portion of the population and average incidence rates for 5 years was observed. In Bashkiriya, immunity was found in 14.9 per cent of men and 11.8 per cent of women. In other regions, the per cent of women with antibodies to HFRS virus was also lower. In the age-group under 40 the percentage of immunity was lower (11.4 per cent) than in older age-groups (17.4 per cent). The portion of immune subjects varied in different occupation groups. In HFRS convalescents the antibody was found to persist in high titre for 20 years (the observation period). (Author)

    Measurements were made of the susceptibility to six commonly prescribed antibiotics, including erythromycin, tetracycline and ciprofloxacin, of 130 isolates of Campylobacterjejuni and 15 isolates of Campylobacter coli cultured from human and poultry sources during 2000. The results were compared with the results from a collection of strains isolated between 1996 and 1998. The levels of resistance to erythromycin remained low, 2 per cent and 4.4 per cent for the human and poultry isolates, respectively. Resistance to tetracycline had increased to 31 per cent and 24.4 per cent from 13.9 per cent and 18.8 per cent for the human and poultry isolates, respectively. However, the resistance to ciprofloxacin of the strains isolated during 2000 had increased to 30 per cent, whereas between 1996 and 1998 there had been no resistance to this agent among human isolates, and only 3.1 per cent resistance among poultry isolates. The molecular basis for this resistance has been shown to be the result of a single amino acid substitution, Thr-86-Ile, in the gyrA subunit of DNA gyrase in Cjejuni. A subset of 59 isolates was tested by molecular methods and all of the 25 phenotypically resistant isolates possessed this substitution. None of the human isolates had been treated with ciprofloxacin before their laboratory isolation.

    The professional and personal characteristics of all physicians recruited into a large urban governmentally sponsored health system were evaluated and correlated to staff retention and loss. The results were tabulated for 84 physicians, approximately 90 per cent of the physician work force, over a three-year period. Eighty per cent resided in either Denver or the state of Colorado prior to entry. This is further reflected in a significant percentage being enrolled in the local medical school or training programs prior to entry. These facts suggest a possible source of manpower for beginning programs. Twenty-six per cent came from private practice, 32 per cent from the military and 14 per cent from the Public Health Service. The turnover rate averaged 6.2 per cent per year, with 4.4 per cent being initiated by the physician and 1.8 per cent leaving because of administrative pressure. Data from other studies are reviewed. Factors which appear to influence retention positively were residency training (pediatricians), sex (females), age (over 38) and those with team experience. These factors suggest directions as to the type of physician who, if recruited, tend to reduce turnover. The establishment of a group practice atmosphere with rewards for clinical skills and the offering of unusual specialty opportunities are proposed as positive factors in the retention of staff.

    Otitis media is a more frequent occurrence in children, and the disease may progress from an acute to chronic state if appropriate and timely intervention is not initiated. A total of 212 children aged 6 months to 10 years were examined and treated for otitis media, in a 13-month hospital-based study. Acute otitis media was diagnosed in 130 (61.3 per cent) of the patients. There were 82 (38.7 per cent) chronic suppurative otitis media cases. The incidence of acute otitis media and chronic suppurative otitis media in the first year of life was 54.6 per cent and 45.1 per cent respectively. Chronic suppurative otitis media patients were assigned to one of three treatment groups. Recovery occurred in 70.4 per cent of amoxicillin-treated patients, in 88.9 per cent of amoxicillin-clavulanic acid treated patients and in 96.4 per cent of culture and antibiotic sensitivity test patients. Relapses were seen only in the amoxicillin (five cases) and amoxicillin-clavulanic acid (two cases) groups. The success rate in patients treated with antibiotics makes this option mandatory for an established diagnosis.

    Ocular trauma is a major cause of visual impairment and morbidity worldwide. To identify the various type of ocular injury in a rural area, determine the presence of any associated visual damage and assess the final visual outcome after treatment. Hospital-based, prospective study conducted over a period of two years. A total of 60 patients of ocular trauma were included. Ocular injuries were more commonly seen in adult (55 per cent) patients who were associated with agricultural work (43.33 per cent). They were more common in male patients (71.67 per cent). Closed globe injury (68.33 per cent) was more common than open globe injury (31.67 per cent). Both in open and closed globe injuries, the commonest object causing injury was a wooden stick. Just 26.7 per cent of the patients had a visual acuity better than 6/60 at presentation; while after completed treatment at two months follow-up, 68.3 per cent had best corrected visual acuity better than 6/60. Agricultural trauma is an important cause of monocular blindness in rural India. The visual outcome depends upon the site and size of the injury and the extent of the ocular damage.

    Studies with 32 P labelled fertilizer on mustard and sunflower showed a marked reduction in drymatter accumulation, total P uptake, per cent Pdff and per cent P utilization at 10.6 dSm -1 level of salinity over normal one. Except drymatter accumulation, the extent of reduction in total P uptake, per cent Pdff and per cent P utilization was of higher magnitude in sunflower as compared to mustard. Application of P either alone or in conjunction with Zn/FYM gave significantly higher values of drymatter yield, total P uptake, per cent Pdff and per cent P utilization in both the crops. Data further, revealed that application of P in conjunction with FYM was found more beneficial as compared to zinc. It was also observed that the per cent P utilization of applied fertilizer in these crops decreased at higher (80 kg P 2 O 5 /ha) level of P. Amongst the varieties of mustard and sunflower, tested, PR-45 of mustard and EC-69874 of sunflower showed higher yield potential and utilization of native soil phosphorus more efficiently, while Pusa Bold of mustard and Surya of sunflower utilized fertilizer phosphorus more efficiently.

    Fluid management in haemodialysis (HD) affects patient experience, morbidity and mortality. Standards for best practice are lacking. A national survey of the United Kingdom was undertaken to define prevalent practice. An online questionnaire was distributed to all UK renal centres. Forty-five of 74 centres (173 dialysis units), serving 62% (n = 14,697) of UK HD population responded. Seventy-eight per cent had no agreed policy for managing fluid balance in patients on HD; 44% did not assess fluid status routinely. Clinical assessment was the norm; 27% used bio-impedance-based device. To achieve a target-weight, 53% reduced weight as far as tolerated. Twenty-two per cent measured residual renal function (RRF). Ninety-one per cent had no policy for fluid overload. Sixty-four per cent restricted salt and water. Ninety-three per cent used diuretics in patients with RRF. Thirty-eight per cent felt management was adequate; 77% felt there was a need for better evidence. Ninety-one per cent would participate in a study addressing this. There is an urgent need for establishing an evidence base on the optimal approaches to fluid management. © 2016 S. Karger AG, Basel.

    Computed tomography (CT)of the thorax and upper abdomen was prospectively evaluated in 84 patients with potentially operable lung cancer. Invasion into the thoracic wall and the mediastinal structures was not accurately demonstrated by CT. For metastatic mediastinal lymph nodes, the sensitivity and specificity of CT were, respectively, 86 per cent and 61 per cent and the positive and negative predictive indices 49 per cent and 91 per cent. For T1, T2 and T3 tumours the negative indices were 100 per cent, 96 per cent and 71 per cent. Positive predictive index did not differ between squamous cell carcinoma and adenocarcinoma. Adrenal metastases were CT-suspected in 17 cases and liver metastases in eight, but were verified by ultrasonography in only one and four cases. CT should be used in preoperative investigation of lung cancer, irrespective of stage. Demonstration of thoracic-wall or mediastinal invasion need not exclude tumour resection. Preoperative mediastinoscopy is indicated if CT shows nodal metastases or if there are signs of tumour invasion, but not in CT-negative T1 or T2 tumour. Abdominal metastases indicated by CT should be investigated with CT-guided needle biopsy. (authors)

    Clinical examination of 2192 psittacine birds of both sexes revealed a prevalence of 2.74 per cent (60 birds) of egg-binding. Domesticated species easily bred in captivity were the most commonly affected; the prevalence in cockatiels (15.75 per cent), and in budgerigars (5.73 per cent). An accurate diagnosis was possible in all cases by means of an evaluation of the case history, a visual examination, palpation and radiographic and ultrasonographic examinations. The case history alone was typical in 60 per cent of the cases, and reliable diagnosis was reached with the help of a visual examination in 70 per cent of the cases. Radiographic examination provided a definitive diagnosis in 30 per cent of the cases, especially in those with shelled eggs. Medullary bone proved to be a radiographic indication of laminated and thin-shelled eggs. However, laminated and thin-shelled eggs could only be differentiated definitively from abdominal masses, salpingitis and cystic degeneration by means of ultrasonography

    A total of 678 cases of soft chancre were treated in one hospital between 1973 and 1979. The majority of the patients were males (97 p. cent), and most of them came originally from Maghreb or Black Africa. Contamination was from prostitution (61 p. cent) or chance acquaintances (29 p. cent). The genital ulceration was often clinically atypical, frequently syphiloid; pain was present in only 59 p. cent of cases, and adenopathy, noted in 63 p. cent of patients, had the appearance of an inflammatory bubo in only 23 p. cent. The present high frequency of soft chancres, and their misleading clinical characteristics, makes it sometimes difficult to establish the clinical differential diagnosis from syphilitic chancre, but confirmation of the latter is supplied by direct examination and culture to search for Ducreys bacillus, this being indispensable for establishing the correct diagnosis. Treatment with sulfamethoxazole trimethopin or streptomycin prevents complications and cures the affection in one or two weeks.

    Full Text Available The results of implementation governmental strategy of the iodine deficiency diseases elimination in the Belarus Republic based on the wide using of iodinated salt is presented. For the control of this program fulfillment more than 1300 children from 6 districts of Republic were examined. Middle Republic level of median of the urine iodine elimination for the period of the program realization has increased in more than 4 times and was equal to 179.2 ug/l and iodine deficiency decreased from 80.9 per cent in 1997 to 14.0 per cent in 2006. Consumption of iodinated salt has increased from 30.0 per cent in 1997 to 93.6 per cent in 2006. As the result the goiter rate in Belarus decreased from 17.2 per cent to 12.8 per cent. These results allow getting conclusion concerning efficiency of the strategy of using the iodinated salt recommended by the UNICEF as universal prophylaxis measure for the iodine deficiency diseases elimination.

    The purpose of this study was to determine which continental European draught horse breeds harbour a mutation in the glycogen synthase 1 gene (GYS1) that is known to be responsible for type 1 polysaccharide storage myopathy in quarter horses and North American draught horses. Of a non-random selection of continental European draught horses belonging to 13 breeds, 62 per cent (250 of 403) tested were found to carry the mutant allele. The horses were located in Belgium, France, Germany, The Netherlands, Spain and Sweden. The mutation was identified in animals from each of the breeds examined. In the breeds in which more than 15 animals were available for testing, the highest percentages of GYS1-positive horses were found in the Belgian trekpaard (92 per cent; 35 of 38 horses tested), Comtois (80 per cent; 70 of 88), Netherlands trekpaard (74 per cent; 17 of 23), Rheinisch-Deutsches kaltblut (68 per cent; 30 of 44) and Breton (64 per cent; 32 of 51).

  9. Multivariate granger causality between electricity consumption, exports and GDP: Evidence from a panel of Middle Eastern countries

    Narayan, Paresh Kumar; Smyth, Russell

    2009-01-01

    This paper examines the causal relationship between electricity consumption, exports and gross domestic product (GDP) for a panel of Middle Eastern countries. We find that for the panel as a whole there are statistically significant feedback effects between these variables. A 1 per cent increase in electricity consumption increases GDP by 0.04 per cent, a 1 per cent increase in exports increases GDP by 0.17 per cent and a 1 per cent increase in GDP generates a 0.95 per cent increase in electricity consumption. The policy implications are that for the panel as a whole these countries should invest in electricity infrastructure and step up electricity conservation policies to avoid a reduction in electricity consumption adversely affecting economic growth. Further policy implications are that for the panel as a whole promoting exports, particularly non-oil exports, is a means to promote economic growth and that expansion of exports can be realized without having adverse effects on energy conservation policies

    Vietnam grew from an insignificant to the world’s second largest coffee producer during the 1990s. To understand this growth, this paper examines Vietnamese coffee growers’ investment decisions using real options theory. The study finds that producers, with variable costs of 19 cents/lb and total cost of 29.3 cents/lb, would enter coffee production at a coffee price of 47 cents/lb and exit at a coffee price of 14 cents/lb. Most Vietnamese growers appear to be sufficiently efficient to continu...

    Feline hepatic lipidosis (HL) is a common, potentially life-threatening disease resulting from prolonged anorexia and increased catabolism. This retrospective study included cats diagnosed with HL based on liver cytology or histopathology (years 2004-2015), and aimed to identify clinical and laboratory parameters associated with mortality. The study included 71 cats (47 females and 24 males) and 85 control cats with non-HL diseases. Most HL cats (90 per cent) were mixed breed, neutered (70; 99 per cent), female (47; 66 per cent), indoor cats (56; 79 per cent), fed dry commercial diets (44 cats; 62 per cent), and with a median age of 7.5 years (range 1.5-16.0). Common primary conditions included gastrointestinal diseases, pancreatitis and cholangiohepatitis (31 cats; 44 per cent) and stressful events (14; 20 per cent). HL was idiopathic in 20 cats (28 per cent). The overall mortality was 38 per cent (27/71 cats). Older age, as well as dullness, weakness, ptyalism, hypoproteinaemia, hypoalbuminaemia, increased serum creatine kinase activity, hypocholesterolaemia and hepatic failure at presentation were significantly (P≤0.033) associated with mortality. The primary disease was unassociated with mortality. Worsening hypoalbuminaemia, hyperammonaemia, hyperbilirubinaemia, electrolyte disorders, and occurrence of cavitary effusions or hypotension during hospitalisation were significantly (P≤0.045) associated with mortality. A decrease of serum β-hydroxybutyrate during hospitalisation was significantly (P=0.01) associated with survival, likely reflecting improvement in the catabolic state. The identified risk factors may be therapeutic targets. © British Veterinary Association (unless otherwise stated in the text of the article) 2017. All rights reserved.

    2009-01-01

    The Government of Malaysia introduced a five-fuel diversification strategy in 1999 to ensure security of energy supply. This strategy will continue until 2020 to reduce Malaysia's dependence on fossil fuels for generating electricity. This paper empirically explored the economic impact of electricity generation and scenario analysis that separately identifies impact on the environment of coal, fuel and hydro generating electricity technologies. It also evaluated emissions of carbon dioxide, sulphur dioxide and nitrogen oxide for the year 1991 and 2000 based on business as usual techniques and projection of those emissions based on business as usual and fuel mix strategy as specified in the fuel diversification strategy. The strategy in the electricity sector aims for a gradual change in fuel use from 74.9 per cent natural gas, 9.7 per cent coal, 10.4 per cent hydro, and 5 per cent petroleum in the year 2000 to 40 per cent natural gas, 30 per cent hydro, 29 per cent coal, and only 1 per cent petroleum by the year 2020. This paper presented the underlying model which is based on input-output techniques. The pollution emission levels from the fossil fuels were estimated. The study revealed that the fuel mix envisioned by the Fuel Diversification Strategy, designed to reduce Malaysia's dependence on fuel oil and increase its energy security would result in an increase in undesired emissions. 16 refs., 5 tabs., 3 figs

    Isotopic analysis of mixtures of plutonium 239 and 240 has been carried out by means of the photo-electric spectrometer Fabry-Perot, the source being a hollow cathode cooled by liquid nitrogen. This first research has been concerned with finding among the spectral lines given by the hollow cathode, those suitable for use in analysis. Actually, the relative precision is of the order of 2 per cent (for samples containing 3 per cent of {sup 240}Pu). The study of the reproducibility of the measurements should make it possible to increase the precision; the relative precision which can be expected from this method should be 1 per cent for mixtures containing 1 per cent of {sup 240}Pu.

    Feeding raw meat-based diets (RMBDs) to companion animals has become increasingly popular. Since these diets may be contaminated with bacteria and parasites, they may pose a risk to both animal and human health. The purpose of this study was to test for the presence of zoonotic bacterial and parasitic pathogens in Dutch commercial RMBDs. We analysed 35 commercial frozen RMBDs from eight different brands. Escherichia coli serotype O157:H7 was isolated from eight products (23 per cent) and extended-spectrum beta-lactamases-producing E coli was found in 28 products (80 per cent). Listeria monocytogenes was present in 19 products (54 per cent), other Listeria species in 15 products (43 per cent) and Salmonella species in seven products (20 per cent). Concerning parasites, four products (11 per cent) contained Sarcocystis cruzi and another four (11 per cent) S tenella In two products (6 per cent) Toxoplasma gondii was found. The results of this study demonstrate the presence of potential zoonotic pathogens in frozen RMBDs that may be a possible source of bacterial infections in pet animals and if transmitted pose a risk for human beings. If non-frozen meat is fed, parasitic infections are also possible. Pet owners should therefore be informed about the risks associated with feeding their animals RMBDs. © British Veterinary Association (unless otherwise stated in the text of the article) 2018.

This separation facilitates the determination of the traces of the heavier yttrium subgroup of rare-earth elements

    During 26 months 200 consecutive patients with fracture of the bony pelvis were evaluated and treated for urological injury. There was no correlation between the extent of pelvic injury and degree of hematuria but hematuria was present in all patients with a urological injury. All urological injuries occurred with anterior arch fractures. The over-all incidence of injury was 13.5 per cent (bladder 9 per cent, urethra 3.5 per cent and combined 1 per cent). Limited extraperitoneal bladder ruptures were treated successfully by Foley catheter drainage.

    Sixty-five patients with possible pancreatic disease or long-standing upper abdominal symptoms were examined by means of the secretin-CCK test and hypotonic duodenography. Both examinations were performed after one duodenal intubation. In patients with pancreatitis functional abnomalities were revealed in 85 per cent while the duodenography was abnormal in 43 per cent. In patients with carcinoma, 77 per cent had abnormal exocrine pancreas function and 70 per cent had abnormalities demonstrated at duodenography. The value of the two examinations for assessment of patients with upper abdominal symptoms and pancreatic disease is discussed. (Auth.)

  20. The Effects of Flattening the Effective Marginal Rate Structure in Australia: Policy Simulations Using the Melbourne Institute Tax and Transfer Simulator

    OpenAIRE

    2001-01-01

    This paper uses the Melbourne Institute Tax and Transfer Simulator (MITTS) to examine the effects of a reduction in the means-tested benefit taper, or withdrawal, rates in Australia to 30 per cent. That is, all taper rates of 50 per cent and 70 per cent in the 1998 system are reduced to 30 per cent, while leaving all basic benefit levels unchanged. This change is therefore expected to ‘flatten’ the tax structure by reducing the high marginal tax rates applying to those with relatively low inc...

  1. Proliferative activity of benign human prostate, prostatic adenocarcinoma and seminal vesicle evaluated by thymidine labeling

    Meyer, J.S.; Sufrin, G.; Martin, S.A.

    1982-01-01

    The thymidine labeling index (TLI) was measured in vitro in the epithelium and stroma of benign prostate glands and seminal vesicles and in the epithelium of prostatic adenocarcinomas. The mean epithelial TLI of normal peripheral (posterior) prostatic zone was 0.12 per cent, and that of the normal central (deep) zone was 0.11 per cent. Mean normal stromal TLI's were 0.08 per cent and 0.06 per cent, respectively. The mean TLI of epithelium in nodular hyperplasia was 0.31 per cent, which differs significantly from normal epithelium, and the mean stromal TLI was also increased. The mean TLI of prostatic adenocarcinomas was 0.90 per cent (range 0.14 to 3.90 per cent) which was significantly higher than for either normal epithelium or epithelium of nodular hyperplasia. Trends of increasing TLI with increasing histologic grades and increasing nuclear size and numbers of nucleoli were not significant. The data support participation of both epithelial and stromal proliferation in nodular hyperplasia, and indicate a low basal proliferative rate in normal prostatic glands. The low TLI's of prostatic adenocarcinomas relative to other malignancies are consistent with their frequently slowly progressive course. The very low proliferative rate of seminal vesicular epithelium may account for the rarity of seminal vesicular carcinomas

    To review the clinical and diagnostic findings and survival of dilated cardiomyopathy from a large population of dogs in England. A retrospective study of the case records of dogs with dilated cardiomyopathy collected between January 1993 and May 2006. There were 369 dogs with dilated cardiomyopathy of which all were pure-bred dogs except for four. The most commonly affected breeds were dobermanns and boxers. Over 95 per cent of dogs weighed more than 15 kg and 73 per cent were male. The median duration of signs before referral was three weeks with 65 per cent presenting in stage 3 heart failure. The most common signs were breathlessness (67 per cent) and coughing (64 per cent). The majority of dogs (89 per cent) had an arrhythmia at presentation and 74 per cent of dogs had radiographic signs of pulmonary oedema or pleural effusion. The median survival time was 19 weeks. Dilated cardiomyopathy occurs primarily in medium to large breed pure-bred dogs, and males are more frequently affected than females. The duration of clinical signs before referral is often short and the survival times are poor. Greater awareness of affected breeds, clinical signs and diagnostic findings may help in early recognition of this disease which often has a short clinical phase.

    Maritime Electric is the electric utility for Prince Edward Island (PEI). This paper outlined the energy supply strategy for the province along with its system performance and improvements. In 1992 the energy supply for PEI was 772 GWh with an energy mix of nuclear, coal, and short term purchases. In 2002, the energy supply mix was similar but the total supply was 1020 GWh. In December 2002, the peak load on the Island exceeded cable capacity. Load growth is projected to continue. The utility buys approximately 65 per cent of its energy under short term contracts. Energy options for PEI include off-island purchases, natural gas, wind, or energy conservation. However, in terms of off-island purchases, no new capacity is planned for either Nova Scotia or New Brunswick and the future of the 630 MW Point Lepreau nuclear power station is not clear. By 2005, PEI expects to have a new 50 MW gas turbine for added reliability. By 2010, the power mix in PEI should include 10 per cent coal, 15 per cent nuclear, 20 per cent short term purchases, 30 per cent new base load supply, 15 per cent intermediate load supply, and 10 per cent wind power. 1 tab., 6 figs

  4. Antibiotics used most commonly to treat animals in Europe

    The Heads of Medicines Agencies and the Federation of Veterinarians of Europe undertook a survey to gain an insight into European prescribing of antibiotics for animals, in particular to highlight the diseases for which antibiotics are most commonly said to be prescribed and which different classes, including human critically important antibiotics (CIAs). The survey was completed by 3004 practitioners from 25 European countries. Many older antibiotics (eg, penicillins, tetracyclines) are cited most frequently as the prescribed classes to treat the main food producing species. The frequency of citation of non-CIAs predominates. CIAs are mostly frequently cited to be prescribed for: urinary diseases in cats (62 per cent), respiratory diseases in cattle (45 per cent), diarrhoea in cattle and pigs (respectively 29 per cent and 34 per cent), locomotion disorders in cattle (31 per cent), postpartum dysgalactia syndrome complex in pigs (31 per cent) and dental disease in dogs (36 per cent). Clear ‘preferences’ between countries can be observed between antibiotic classes. The use of national formularies and guidance helps to drive responsible use of antibiotics and can significantly reduce the extent of use of CIAs. A more widespread introduction of veterinary practice antibiotic prescribing policies and monitoring obedience to these should ensure more widespread compliance with responsible use guidelines.

    This study, carried out during August-October, 1991, involved 236 respondents to a questionnaire designed to determine awareness and attitudes to AIDS and the consequent effect of such awareness on their sexual behaviour. Almost all the medical students were aware of the existence of the disease, while a few (3.8 per cent) of the non-medicos believed that it had not yet reached Nigeria. Most students i.e. 98 per cent and 97 per cent of these respective groups were aware of carrier state of the disease. Only a small percentage of students, mostly medics knew about the exact signs and symptoms of clinical AIDS. The level of knowledge about the modes of transmission of AIDS was found to be adequate. With regard to the effect of this awareness on their behaviour, it was known that a good number of medics (30.37) per cent and non-medics (28.88) per cent had started using condoms. About 40 per cent medicos, and 45 per cent non-medicos revealed an aversion to sit near a person with AIDS thus emphasizing the stigma associated with the disease. Regarding control of AIDS, many felt there should be strict isolation of HIV positive individuals along with a ban on prostitution and homosexuality.

    For more than a century, appendicectomy has been the treatment of choice for appendicitis. Recent trials have challenged this view. This study assessed the benefits and harms of antibiotic therapy compared with appendicectomy in patients with non-perforated appendicitis. A comprehensive search was conducted for randomized trials comparing antibiotic therapy with appendicectomy in patients with non-perforated appendicitis. Key outcomes were analysed using random-effects meta-analysis, and the quality of evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. Five studies including 1116 patients reported major complications in 25 (4·9 per cent) of 510 patients in the antibiotic and 41 (8·4 per cent) of 489 in the appendicectomy group: risk difference -2·6 (95 per cent c.i. -6·3 to 1·1) per cent (low-quality evidence). Minor complications occurred in 11 (2·2 per cent) of 510 and 61 (12·5 per cent) of 489 patients respectively: risk difference -7·2 (-18·1 to 3·8) per cent (very low-quality evidence). Of 550 patients in the antibiotic group, 47 underwent appendicectomy within 1 month: pooled estimate 8·2 (95 per cent c.i. 5·2 to 11·8) per cent (high-quality evidence). Within 1 year, appendicitis recurred in 114 of 510 patients in the antibiotic group: pooled estimate 22·6 (15·6 to 30·4) per cent (high-quality evidence). For every 100 patients with non-perforated appendicitis, initial antibiotic therapy compared with prompt appendicectomy may result in 92 fewer patients receiving surgery within the first month, and 23 more experiencing recurrent appendicitis within the first year. The choice of medical versus surgical management in patients with clearly uncomplicated appendicitis is value- and preference-dependent, suggesting a change in practice towards shared decision-making is necessary. © 2016 The Authors.

    This work describes differential effects of solvent in complexes of the aminoglycoside phosphotransferase(3 and cent;)-IIIa (APH) with different aminoglycosides and the detection of change in solvent structure at specific sites away from substrates. Binding of kanamycins to APH occurs with a larger negative and cent;H in H2O relative to D2O ( and cent; and cent;H(H2O-D2O) < 0), while the reverse is true for neomycins. Unusually large negative and cent;Cp values were observed for binding of aminoglycosides to APH. and cent;Cp for the APHneomycin complex was -1.6 kcal and acirc;mol-1 and acirc;deg-1. A break at 30 C was observed in the APH-kanamycin complex yielding and cent;Cp values of -0.7 kcal and acirc;mol-1 and acirc;deg-1 and -3.8 kcal and acirc;mol-1 and acirc;deg-1 below and above 30 C, respectively. Neither the change in accessible surface area ( and cent;ASA) nor contributions from heats of ionization were sufficient to explain the large negative and cent;Cp values. Most significantly, 15N-1H HSQC experiments showed that temperature-dependent shifts of the backbone amide protons of Leu 88, Ser 91, Cys 98, and Leu143 revealed a break at 30 C only in the APH-kanamycin complex in spectra collected between 21 C and 38 C. These amino acids represent solVent reorganization sites that experience a change in solvent structure in their immediate environment as structurally different ligands bind to the enzyme. These residues were away from the substrate binding site and distributed in three hydrophobic patches in APH. Overall, our results show that a large number of factors affect and cent;Cp and binding of structurally different ligand groups cause different solvent structure in the active site as well as differentially affecting specific sites away from the ligand binding site

  11. Coagulation Profile Changes Due to Thromboprophylaxis and Platelets in Trauma Patients at High-Risk for Venous Thromboembolism.

    We hypothesize there are coagulation profile changes associated both with initiation of thromboporphylaxis (TPX) and with change in platelet levels in trauma patients at high-risk for venous thromboembolism (VTE). A total of 1203 trauma intensive care unit patients were screened with a VTE risk assessment profile. In all, 302 high-risk patients (risk assessment profile score ≥ 10) were consented for weekly thromboelastography. TPX was initiated between initial and follow-up thromboelastography. Seventy-four patients were analyzed. Upon admission, 87 per cent were hypercoagulable, and 81 per cent remained hypercoagulable by Day 7 (P = 0.504). TPX was initiated 3.4 ± 1.4 days after admission; 68 per cent received unfractionated heparin and 32 per cent received low-molecular-weight heparin. The VTE rate was 18 per cent, length of stay 38 (25-37) days, and mortality of 17.6 per cent. In all, 76 per cent had a rapid clotting time at admission versus 39 per cent at Day 7 (P < 0.001); correcting from 7.75 (6.45-8.90) minutes to 10.45 (7.90-15.25) minutes (P < 0.001). At admission, 41 per cent had an elevated maximum clot formation (MCF) and 85 per cent had at Day 7 (P < 0.001); increasing from 61(55-65) mm to 75(69-80) mm (P < 0.001). Platelets positively correlated with MCF at admission (r = 0.308, R(2) = 0.095, P = 0.008) and at Day 7 (r = 0.516, R(2) = 0.266, P < 0.001). Change in platelet levels correlated with change in MCF (r = 0.332, R(2) = 0.110, P = 0.005). In conclusion, hypercoagulability persists despite the use of TPX. Although clotting time normalizes, MCF increases in correlation with platelet levels. As platelet function is a dominant contributor to sustained trauma-evoked hypercoagulability, antiplatelet therapy may be indicated in the management of severely injured trauma patients.

  19. 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.

These taxes comprise energy taxes (nearly 68 per cent), transport taxes (nearly 28 per cent) and pollution and resource taxes (less than 5 per cent), and represent 2 per cent of the French GDP and 5 per cent of mandatory contributions. The share of environmental taxes is compared among the European Union countries. This shows that France is close to the average. It also appears that these taxes evolve slower than the GDP. An indicator is built up and commented: it relates the rate between energy taxes and the GDP on the one hand, and energy consumption on the other hand. This indicator displays a slow but significant decrease since the end of the last century

    There is little published evidence on what doctors do in their work that requires probability and statistics, yet the General Medical Council (GMC) requires new doctors to have these skills. This study investigated doctors' use of and attitudes to probability and statistics with a view to informing undergraduate teaching.An email questionnaire was sent to 473 clinicians with an affiliation to the University of East Anglia's Medical School.Of 130 respondents approximately 90 per cent of doctors who performed each of the following activities found probability and statistics useful for that activity: accessing clinical guidelines and evidence summaries, explaining levels of risk to patients, assessing medical marketing and advertising material, interpreting the results of a screening test, reading research publications for general professional interest, and using research publications to explore non-standard treatment and management options.Seventy-nine per cent (103/130, 95 per cent CI 71 per cent, 86 per cent) of participants considered probability and statistics important in their work. Sixty-three per cent (78/124, 95 per cent CI 54 per cent, 71 per cent) said that there were activities that they could do better or start doing if they had an improved understanding of these areas and 74 of these participants elaborated on this. Themes highlighted by participants included: being better able to critically evaluate other people's research; becoming more research-active, having a better understanding of risk; and being better able to explain things to, or teach, other people.Our results can be used to inform how probability and statistics should be taught to medical undergraduates and should encourage today's medical students of the subjects' relevance to their future careers.

    Full Text Available The composition of free amino acids was studied from leaves, pericarps, skins, musts and seeds of Vitis vinifera L. cv. Cabernet Sauvignon. Vineyards were in the Bordeaux region and the grapevines were conducted in espalier and lyre systems. Grapes were collected at maturity and lyophilized after sampling. Extraction of free amino acids was done with a hydroalcoholic solution and their analysis was performed with an autoanalyzer. A standard of 34 amino acids was utilized for the qualitative analysis. The results showed that, for both espalier and lyre training systems, respectively, the free amino acids were predominant in the pericarps (12.85 and 11.21 mg/g dw - 16.88 and 15.12 mg/g dw in skins and 3.29 and 2.88 g/l in musts -, followed by the seeds (2.37 and 2.32 mg/g dw and leaves (1.87 and 1.98 mg/g dw. The most abundant free amino acids in leaves were glutamic acid (23.8 and 28.8 p. cent, aspartic acid (8.8 and 11.1 p. cent, and glutamine (10.1 and 9.4 p. cent. Proline (41.8 and 41.5 p. cent and arginine (22.8 and 22.4 p. cent predominated in the pericarps. In seeds, the main amino acids were proline (14.5 and 15.8 p. cent, arginine (11.0 and 11.8 p. cent, histidine (11.2 and 8.7 p. cent, and glutamic acid (11.3 and 8.2 p. cent. Grapevine training system showed some differences in the total amount and in the percentages of each free amino acid, but the pattern of these compounds for each tissue was similar for both training systems.

    Full Text Available Background The relationship between baldness and heart disease is still controversial. We performed an updated meta-analysis of observational studies to evaluate the relation between heart disease and androgenic alopecia or alopecia areata. Aims To evaluate the relation between heart disease and androgenic alopecia or alopecia areata. Methods Studies were identified by searching Medline and Embase up to October 20, 2017 without language restriction. Metaanalysis was performed by using a random-effects model. Results Nine studies were included in the meta-analysis (eight on androgenic alopecia and one on alopecia areata: 44,806 participants. Compared to men without baldness, men with androgenic alopecia had an increased risk of heart disease (relative risk (RR: 1.32, 95 per cent CI: 1.08 to 1.63, p=0.01, I2 =25 per cent, and younger men (<55 or ≤60 years showed a stronger association (RR: 1.44, 95 per cent CI: 1.11 to 1.86, p=0.01, I2 =0 per cent. The positive relation depended on the severity of baldness and decreased in order of severe vertex (RR: 1.60, 95 per cent CI: 1.19 to 2.16, p=0.002, moderate vertex (RR: 1.41, 95 per cent CI: 1.22 to 1.64, p<0.001, mild vertex (RR: 1.18, 95 per cent CI: 1.05 to 1.33, p=0.007, and frontal baldness (RR: 1.10, 95 per cent CI: 0.92 to 1.32, p=0.28. In contrast, there was no significant relation between alopecia areata and heart disease (RR: 0.91, 95 per cent CI: 0.60 to 1.39, p=0.66. Conclusion Androgenic alopecia is associated with heart disease, but alopecia areata is not.

This was a retrospective study using information from patients' notes. All patients with large multinodular goitres who had radioiodine therapy for treatment of MNG since 1991 were selected. Data obtained included age, gender, pre, peri and post therapy symptoms and serial biochemical thyroid function results. Each patient was followed for a minimum of six months. The subjects were 35 patients (32 female, three male) with an age range of 37 - 87 years. 26 patients had non-toxic MNG, nine patients had toxic MNG, 24 patients had retrosternal or obstructive symptoms and five patients had had previous thyroid therapy. The patients with retrosternal or obstructive symptoms experienced a reduction in those symptoms. 8.6 per cent of the patients experienced no change at all in symptoms. 2.8 per cent of the patients experienced non-transient side effects (sore throat). 32.8 per cent of the patients experienced transient hyperthyroidism during 131 I therapy. In the toxic group, 77.8 per cent became euthyroid. 11.1 per cent became hypothyroid and 11.1 per cent remained hyperthyroid and required additional treatment. In the non-toxic group, 42.3 per cent became hypothyroid and 57.7 per cent remained euthyroid. The overall incidence of hypothyoidism was 34.4 per cent. The results of this study suggests 131 l therapy in the form of 4 x 555 MBq oral doses (one dose per month for four months) is effective, efficient, relatively risk-free, easy and generally well-tolerated treatment for toxic and non-toxic multinodular goitre

    A typical inspection of steel utility poles routinely overlooks what is below ground, such as anchor rods, stub angles in lattice towers, and direct embedded steel poles. Stub angles are lap or butt spliced to the tower leg and extend several feet below ground line. A case study concerning stub angles (Oberst 1998) is discussed. An inspection of steel poles erected in 1929 revealed that 40 per cent of legs had complete loss of galvanizing, 10 per cent of legs had greater than 10 per cent loss of cross-section, and 2 per cent of legs had greater than 80 per cent loss of cross-section. All corrosion was found within one foot of ground line. A relatively new concept is direct embedded steel poles. An emerging problem concerns tree induced anchor rod corrosion. A corrosion technique for anchor rods was developed and has been commercially available for the past three years. Its effectiveness was verified at the Montana Power Company 500 kV Colstrip Project, where 3 anchor failures were detected in 1995 due to corrosion wastage. The rods are classified as being in good condition up to 10 per cent loss of cross-section, moderate corrosion for losses between 10 and 25 per cent, and excessive corrosion for losses greater than 25 per cent. The results obtained at the Montana Power Company indicated the technique was 98 per cent accurate. The authors discuss the capabilities and limitations of the technique. It was also applied for the Anchor Rod Inspection Project of the Georgia Power Company (GPC). The technique is evaluated in the laboratory, then optimized. Field prototypes are developed, followed by an evaluation at different test sites. figs.

    Full Text Available Background Despite the abundance of sunshine throughout the year, vitamin D deficiency is very prevalent among different Saudi populations. Aims The objective of the current study was to evaluate the awareness and intake of vitamin D rich sources and their associations among adults of both genders. Methods A cross-sectional study was performed between June 2016 and August 2016 among adult patients and their family members (>18 years attending 6 primary care centres in Qassim region, Saudi Arabia. Results A total of 500 study participants were included in the current analysis. Approximately 54.6 per cent of the participants were males and the most frequent age was 26–50 years. The majority of the participants heard of vitamin D before (91.4 per cent, believed in its importance for health (92.8 per cent, were aware of the symptoms of vitamin D deficiency (72.6 per cent, and were able to identify sun exposure (81.4 per cent and diet (70.4 per cent as sources. The sources of vitamin D used by the participants were sun exposure (57.2 per cent, vitamin D rich foods (51.2 per cent and supplements (18.8 per cent. There was a significant association between overall awareness of vitamin D and intake of at least 2 sources of vitamin D in males (p < 0.001 but not females (p=0.920. Although females had better awareness than males, sun exposure was much lower among females than males. Conclusion As supplementation was very low in both gender and since cultural factors promoting limited sun exposure among females are not easily modifiable, the current findings further highlight the critical importance of vitamin D supplementation, especially among females in Saudi Arabia.

    Emissions inventories are used by government agencies as a tool for policy development and air quality management. Marine vessels have been identified as a major source of anthropogenic pollution in British Columbia. This report presents estimates of emissions from marine vessels in coastal areas in British Columbia outside of the Greater Vancouver Regional District (GVRD), the Fraser Valley Regional District (FVRD), and in Washington State for the year 2000. The project includes an update of emission estimates for each marine vessel category and an update of emission estimates for pollutants of interest, including carbon monoxide (CO), nitrogen oxides (NOx), particulate matter (PM), sulphur oxides (SOx), volatile organic compounds (VOCs), as well as inhalable fine particulates (PM10 and PM2.5) and greenhouse gases such as carbon dioxide, methane, nitrous oxide and ammonia. This report presented emissions results for both the Canadian and U.S. portions. It also includes both spatial and temporal allocation of emissions. Results indicate that ocean-going vessels are the major contributor to emissions of NOx, SOx, PM and greenhouse gases, accounting for 56, 93, 83, and 51 per cent of the total marine vessel emissions respectively. They also contribute 30 and 33 per cent to the marine totals for CO and VOCs. Harbour vessels contribute 22 and 24 per cent of NOx and greenhouse gases and 17 per cent of both CO and VOCs. Ferries contribute between 15 per cent and 23 per cent for CO, VOC, NOx and GHGs, but less than 9 per cent for SOx and PM. Fishing vessels contribute 1 per cent or less of all contaminants. Although recreational vessels are major contributors for CO and VOC, they contribute less than 2 per cent for all other contaminants. A comparison of 1995 and 2000 marine vessel inventory for British Columbia was presented and recommendations for improvements were presented. refs., tabs., figs.

    This study estimated the prevalence of negative self-perception of smile because of occlusion abnormalities and investigated their association according to standard clinical criteria. The sample consisted of 1290 randomly selected Brazilian adolescent boys and girls aged 12-16 years. The outcome of interest was dissatisfaction with smile, and data were collected using a standardized questionnaire. Occlusion characteristics were assessed using the dental aesthetic index (DAI). The other study variables were gender, age, and use of dental services. A chi-square test and Poisson multiple regression were used for statistical analysis. Of the 1290 students interviewed and examined, 539 (41.8 per cent) were dissatisfied with their smile; of these, 373 (69.2 per cent) assigned their dissatisfaction to the presence of an occlusal abnormality, and 166 (30.8 per cent) reported reasons other than occlusal abnormalities for their negative self-perception of their smile. In multivariate analysis, the following variables were associated with the outcome of interest: maxillary anterior irregularity [prevalence ratio (PR) = 1.40; 95 per cent confidence interval (CI) = 1.29-1.80], incisal spacing (PR = 1.37; 95 per cent CI = 1.19-1.57), vertical open bite (PR = 1.34; 95 per cent CI = 1.15-1.55), mandibular anterior irregularity (PR = 1.29; 95 per cent CI = 1.14-1.46), permanent anterior teeth missing (PR = 1.21; 95 per cent CI = 1.05-1.39), and incisal diastema (PR = 1.14; 95 per cent CI = 1.01-1.31). The negative self-perception of smile was statistically associated with severity of occlusal disorders according to the DAI scores, which suggests that self-perception should be used together with standard clinical criteria when decisions about orthodontic treatments are made in public health care systems.

    This study was conducted to explore authorship characteristics and publication trends of all orthodontic randomized controlled trials (RCTs), systematic reviews (SRs), and meta-analyses (MAs) published in non-orthodontic journals with impact factor (IF). Appropriate research strategies were developed to search for all articles published until December 2015, without restrictions regarding language or publication status. The initial search generated 4524 results, but after application of the inclusion criteria, the final number of articles was reduced to 274 (SRs: 152; MAs: 36; and RCTs: 86). Various authorship characteristics were recorded for each article. Frequency distributions for all parameters were explored with Pearson chi-square for independence at the 0.05 level of significance. More than half of the included publications were SRs (55.5 per cent), followed by RCTs (31.4 per cent) and MAs (13.1 per cent); one hundred seventy-eight (65 per cent) appeared in dental journals and 96 (35 per cent) were published in non-dental journals. The last decade was significantly more productive than the period before 2006, with 236 (86.1 per cent) articles published between 2006 and 2015. European countries produced 51.5 per cent of the total number of publications, followed by Asia (18.6 per cent) and North America (USA and Canada; 16.8 per cent). Studies published in journals without IF were not included. Level-1 evidence orthodontic literature published in non-orthodontic journals has significantly increased during 2006-15. This indicates a larger interest of other specialty journals in orthodontic related studies and a trend for orthodontic authors to publish their work in journals with impact in broader fields of dentistry and medicine. © The Author(s) 2017.

    Cultures obtained from pre-operative middle-ear swabs from patients with chronic otitis media have traditionally been used to guide antibiotic selection. This study investigated changes in the bacterial strains of the middle ear during chronic otitis media surgery. Pre-operative bacterial cultures of otorrhoea, and peri-operative cultures of the granulation tissue in either the middle ear or mastoid cavity, were obtained. Post-operative cultures were selectively obtained when otorrhoea developed after surgery. Bacterial growth was observed in 45.5 per cent of pre-operative cultures, 13.5 per cent of peri-operative cultures and 4.5 per cent of post-operative cultures. Methicillin-resistant Staphylococcus aureus was identified as the most common bacteria in all pre-operative (32.4 per cent), peri-operative (52.4 per cent) and post-operative (71.4 per cent) tests, and the percentage of Methicillin-resistant S aureus increased from the pre- to the post-operative period. The bacterial culture results for post-operative otorrhoea showed low agreement with those for pre-operative or peri-operative culture, and strain re-identification was required.

    Water is scarce and, in general, a low quality resource in desert areas and the Indian desert is no exception. With this in view, the present study was taken up to survey the status of common water-borne diseases epidemiological trends in the desert city Bikaner (NW Rajasthan). In the city, 15.5 per cent population and 44.5 per cent families were found to suffer from one or more common water-borne diseases including amoebiasis, diarrhoea, dysentery, jaundice and typhoid. No case of fluorosis was recorded. The highest incidence was that of diarrhoea (5.4 per cent population). The worst affected and safe zones in the city were identified and the trends of different diseases in different zones of the city are discussed. The highest incidence of diseases was noted during summer (58.8 per cent) followed by winter (34.1 per cent) and monsoon (7.0 per cent). Relationship of diseases with population attributes like age, education, economy and family size are also discussed. Attributes for contamination of drinking water have been tried to identify and safety measures suggested.

    Full Text Available This study investigates the economic impact of a land tax implemented under the Local Government Municipal Property Rates Act No. 6 of 2004 on commercial farms using five case studies with five-year data sets in the Mtonjaneni and Umgeni municipal districts of KwaZulu-Natal. The case farms’ ability to pay annual rates between 0.25 per cent and 1 per cent of the value of improved land using real annual economic profit with and without rebates of up to 70 per cent proposed by the Department: Provincial and Local Government ranged from zero to five out of five years, with a mean of two out of five years. A 2 per cent land tax rate with such rebates could also be financed only in two out of five years on average. These results suggest that proposed annual land tax rates of 1.5 per cent (Mtonjaneni or 1 per cent (Umgeni on these specific farms would markedly reduce the incentive to invest in farm improvements

    Full Text Available Fifty-seven patients with failed sclerotherapy received a mesocaval interposition shunt with an externally supported, ringed polytetrafluoroethylene prosthesis of either 10 or 12 mm diameter. Thirty-one patients had Child-Pugh gradeA disease and 26 grade B; all had a liver volume of 1000– 2500 ml. Follow-up ranged from 16 months to 6 years 3 months. Three patients (5 per cent died in the postoperative period. There were two postoperative recurrences of variceal haemorrhage and one recurrent bleed in the second year after surgery. The cumulative shunt patency rate was 95 per cent and the incidence of encephalopathy 9 per cent; the latter was successfully managed by protein restriction and/or lactulose therapy. The actuarial survival rate for the whole group at 6 years was 78 per cent, for those with Child-Pugh grade A 88 per cent and for grade B 67 per cent. Small-lumen mesocaval interposition shunting achieves portal decompression, preserves hepatopetal flow, has a low incidence of shunt thrombosis, prevents recurrent variceal bleeding and is not associated with significant postoperative encephalopathy.

    Isotope analysis of uranium is made by means of hollow cathode lamp and Fabry-Perot photoelectric spectrometer. When using the line U I 5027 A, this method allows to determine isotopic concentrations in {sup 235}U down to 0,1 per cent. The relative precision is about 2 per cent for amounts of {sup 235}U over 1 per cent. For weaker amounts this line would allow relative measurements of better precision when using standard mixtures. (author) [French] L'analyse isotopique de l'uranium est effectuee a l'aide d'une lampe a cathode creuse et du spectrometre Fabry-Perot photo-electrique. On utilise la raie U I 5027 A. Cette methode permet de doser des melanges isotopiques dont la teneur en {sup 235}U, peut descendre jusqu'a 0,1 pour cent. La precision relative est de l'ordre de 2 pour cent pour des teneurs en {sup 235}U superieures a 1 pour cent. Pour des teneurs plus faibles cette raie {lambda} = 5027 A permettrait des mesures relatives de meilleure precision, en utilisant des melanges prealablement doses. (auteur)

    Full Text Available On 3 August 2016 South Africa held its fifth local government elections (LGE since the end of Apartheid in 1994. Against a backdrop of increasing political frustration with the ruling party’s poor performance and continued debates about corruption and cronyism in the highest government circles, the African National Congress (ANC maintained its dominant position but lost 8 per cent of the aggregate vote (53.91 per cent. The Democratic Alliance (DA gained some 3 per cent (26.89 per cent of the vote, and the Economic Freedom Fighters (EFF, first-time LGE campaigners, garnered 8.02 per cent. Importantly, the ANC lost control of three of the seven big metropolitan municipalities it had previously held. Since there was no clear-cut majority in four of the eight metros, coalition politics and the art of compromise will become a major feature of South African politics in the coming years. The elections were highly competitive and considered free and fair. At 57.97 per cent, voter turnout was slightly higher than in 2011.

    Hydroxyurea was evaluated as a possible radiation sensitizer in 130 evaluable women with Stages IIB and IIIB (International Federation of Gynecology and Obstetrics) carcinoma of the uterine cervix. This was a prospective double-blind randomized study in which hydroxyurea or placebo was compared in conjunction with continuous or split-course radiation therapy. Of all patients with Stage IIB cancer without biopsy proof of aortic node metastasis, a significant improvement in survival (P < 0.01) was achieved in the hydroxyurea group (74.0 per cent) as compared to the patients receiving placebo (43.5 per cent). In women with Stage IIIB cervical cancer there was a trend toward longer survival in those receiving hydroxyurea (52.1 per cent) as compared to those receiving placebo (33.3 per cent). However, there was a statistically significant improvement in survival in those women with Stage IIIB cervical cancer who had staging done at operation, were found to have negative para-aortic nodes, and subsequently received continuous radiation therapy (90.9 per cent) as compared to those receiving split-course therapy (29.4 per cent)

    Pancreas scintigraphy with 75 seleno-methionine, pancreocimine-secretine test and selective abdominal angiography was carried out in patients with chronic pancreatitis, pancreas carcinoma and subjects without any pancreas diseases. Scintigraphic changes in pancreas was found in 95,6 per cent of the patients with chronic pancreatitis (136 patients), in 92 per cent of them with pancreas carcinoma (25 patients) and in 53,4 per cent from the subjects without pancreas diseases (30 examined). Pathological changes in pancreatic secretion was found in 93,4 per cent of the patients with chronic pancreatitis (105 patients), in 93,8 per cent of the subjects with pancreas carcinoma (32 patients) and only in 3,9 per cent from the examined without pancreatic diseases. The angiographic examination is informative mainly in case of tumours and cysts of the pancreas.

  12. Do Municipal Governments Need More Tax Powers? A Background Paper on Municipal Finance in Alberta

    Directory of Open Access Journals (Sweden)

    2014-11-01

    Full Text Available Local governments in Alberta have faced considerable and variable challenges over the past 60 years. For example, the rapid population and economic growth during the 1950s, ’60s and ’70s created exceptional demands for schools, schooling and municipal infrastructure; demands exceeding those of the last 30 years. Local and especially municipal financing has relied heavily on the property tax throughout. Questions are being asked today about whether the property tax is sufficient for municipal government. Our historical analysis provides insights into the fiscal situation of Alberta’s municipalities that can assist in addressing those questions. The main findings are highlighted here. We conclude that current demands, though considerable, are not creating stress on the property tax as a source of municipal revenue. • The property tax burden in Alberta during the past decade is the lowest that it has been over the past 60 years. Presently, property taxes are about 3.5 per cent of personal income. They were as high as seven per cent during much of the 1960s and averaged in the four to five per cent range from 1950 to 2000. Local and provincial school taxes were responsible for most of the fluctuations in the property tax burden. Municipal property taxes ranged from two to three per cent of personal incomes and recently amounted to about 2.5 per cent, a level typical of that over the past 20 years. • Investment in local infrastructure has over the past 30 years been at half the rate of that of the previous 30 years. Only since 2006, with the assistance of provincial capital grants, has infrastructure spending shown upward movement. Capital spending lagged population growth for many years and probably contributed to a deterioration of infrastructure. • Municipal current or operating expenditures (about three-quarters of the total have been a declining share of personal incomes since the late 1980s and, since 2000, are a smaller share than

    2008-07-01

    Optometry is a regulated health profession in NZ, with limited student places. With 650 registered optometrists in 2005, the optometrist to population ratio was 1 : 6,291 with no apparent national shortage. If optometrists registered in NZ do not actually live there, a workforce shortage is possible. This paper presents findings from the New Zealand Association of Optometrists 2006 workforce survey of members, which aimed to profile the NZ optometric workforce and to explore factors relating to workforce capacity, job stress and future planning. A questionnaire was developed to collect information on employment status, hours worked and gender distribution of optometrists in New Zealand. It was circulated to 530 active members of the NZ Association of Optometrists representing 86 per cent of the available optometrists. Direct comparisons with the Australian optometric workforce numbers were also undertaken. Of the 243 respondents, 129 (53 per cent) were male. The median age of all respondents was 39 years (46 for males and 34 for females) and 75 per cent of the respondents were aged younger than 50 years. Fifty per cent had practised 15 years or less. Ten per cent of respondents had 'time-out' during their career and this was significantly more likely for females. Nearly half the respondents were self-employed (46 per cent) and eight per cent worked as locums. Part-time employees were more likely to be female and males were more likely to be in full-time self-employment. Half the group was under 40 (51 per cent), which accounted for 86 per cent of the full-time salaried arrangements. Those aged 30 to 39 included 52 per cent of the total part-time salaried workers. The average working week was 34 hours for women and 39 hours for men; the median was 40 hours for both groups. In the typical working week, 80 per cent of an optometrist's time was spent consulting with patients and five per cent was patient-related paperwork. The distribution of work arrangements was

    A review of Central Main Power Co.'s service load was presented. In 1996 the company had a total revenue of $967 million and provided electricity to 520,000 customers with total energy sales of 9 billion kwh to the residential, commercial and industrial sectors. The company's energy mix is 32 per cent non-utility, 19 per cent nuclear, 17 per cent hydro, 16 per cent Canadian/other, and 16 per cent oil. The anticipated effects of natural gas pipelines coming on-stream late in 1998 and 1999 were reviewed. It was noted that currently there are 11 merchant power plants under development for a total of 3,940 megawatts of generating capacity for the years 1998-2001. The approach that Central Main Power expects to take to maintain its market share in the face of these developments was outlined. 4 figs

    1994-01-01

    Monazite, a thorium-bearing mineral, has been identified in the heavy mineral fractions of the fine sands from the alluvial soil profiles at Barpalia and Gyaspur of Siwan district in north Bihar. The amount of monazite varied from 14.29 to 15.40 per cent and 6.25 to 9.38 per cent of the heavy minerals in the fine sands of Barpalia and Gyaspur, respectively. Monazite could have been derived from the granite pegmatite and gneissic metamorphic rocks in association with feldspar, zircon and apatite from the Himalayan orogan. The amount of 232 Th present in monazite originally ranges from a few wt per cent ThO 2 to 10-12 per cent. Even in the east coast of India , monazite contains 9.05 per cent ThO 2 .

    A summary of spills reported to the Ontario Ministry of Environment and Energy during 1995 was presented. The Ministry's Spill Action Centre is on call 24-hours per day to receive and respond to reports of spills and other urgent environmental incidents. Some 5,000 spills were documented in 1995. Oils and fuels accounted for 59 per cent of the spilled materials, chemicals and chemical solutions for 17 per cent, wastes and waste waters for 16 per cent, and gaseous materials for 5 per cent. Unknown materials accounted for 3 per cent. Most of the spills involved small volumes. Equipment failure and operator error were the major reasons for spills. All occurrences reported are stored on a computerized database. The information is used to develop new pollution abatement programs and spill prevention initiatives as trends are identified. 14 tabs., 14 figs

    Biodiesel is derived from triacylglycerides and is produced primarily through transesterification, a chemical reaction of vegetable oils with alcohol, methanol or ethanol. The cost of raw material should be considered since 85 per cent of production cost is related to vegetable oil. The purpose of this study was to evaluate oil expression of sunflower seed. It also examined the sunflower crude oil as a raw material for biodiesel by transesterification in both laboratory and pilot scale studies. Three different biodiesel purification methods were examined. The best result for oil expelling (68.4 per cent) at the experimental stage was obtained for seeds with a moisture content of 6.9 per cent at 25 degrees C and at a screw speed of 114 rpm. For biodiesel production at the laboratory scale, the best result for oil expelling was 87.5 per cent. It was obtained with an ethanol:oil molar ratio of 4.7:1 and with a 4.42 per cent catalyst concentration related to the quantity of oil that had to be transesterified. The experimental condition was applied at a bigger scale with a batch stirred tank reactor. For purification with washing, the biodiesel yield was 84.2 per cent. Purification with silica resulted in a yield of 84.6 per cent. A better quality biofuel was obtained through distillation of biodiesel.

  2. Effect of gamma irradiation in the viscosity of gelatin and pectin solutions used in food industry

    Inamura, Patricia Yoko

    2008-01-01

    Pectin is a polysaccharide substance of plant origin that may be used as gelling agent, stabilizer in jams, in yogurt drinks and lactic acid beverages. Gelatin, a protein from bovine origin, in this case, is mainly used as gelling agent due to hydrogel formation during cooling. The 60 Co-irradiation process may cause various modifications in macromolecules, some with industrial application, as reticulation. The dynamic response of viscoelastic materials can be used in order to give information about the structural aspect of a system at molecular level. In the present work samples of pectin with different degree of methoxylation, gelatin and the mixture of both were employed to study the radiation sensitivity by means of viscosity measurements. Solutions prepared with citric pectin with high methoxylation content (ATM) 1 por cent, pectin with low content (BTM) 1 por cent, gelatin 0.5 por cent, 1 por cent and 2 por cent, and the mixture 1 por cent and 2 por cent were irradiated with gamma rays at different doses, up to 15 kGy with dose rate about 2 kGy/h. After irradiation the viscosity was measured within a period of 48 h. The viscosity of ATM and BTM pectin solutions decreased sharply with the radiation dose. However, the gelatin sample presented a great radiation resistance. When pectin and gelatin solutions were mixed a predominance of pectin behavior was found. (author)

    There are no guidelines for antimicrobial use in experimental animals even though appropriate selection is required to reduce risk of surgical site infection (SSI) and resistance development. Pigs are used extensively as experimental surgical models for people. This review compares reported antimicrobial prescription in recently published pig surgical studies (retrieved by PubMed, Web of Knowledge and Google Scholar) with human guidelines for prophylactic antimicrobial use (National Institute of Clinical Excellence and the American Society of Health-System Pharmacists). A five-point appropriate antimicrobial use index (AAUI), based on aforementioned guidelines, was used to grade 233 studies. Use of World Health Organization-designated critically important antimicrobials (CIA) was recorded. Antimicrobial use was described in 111 of 233 (48 per cent) papers. AAUI scores of 5 (maximal compliance) and 0 (no compliance) were awarded to 34 (15 per cent) and 101 (43 per cent) articles. Where reported, prophylactic antimicrobials were mostly administered after surgery (62/95, 65 per cent) and intramuscularly (36/72, 50 per cent). CIAs were described in 21 of 111 (19 per cent) papers and SSIs in 21 of 233 (9 per cent). Reported antimicrobial prophylaxis in experimental pig surgery deviates from human clinical guidelines. This has implications for antimicrobial resistance, study quality and animal welfare. Until species-specific guidelines are formulated, experimental surgical studies involving animals would probably benefit from adherence to human guidelines. British Veterinary Association.

    Full Text Available The basaltic landscape planning on the hot semiarid ecosystem in cotton growing Yavatmal district, Maharashtra tends to concentrate on 52 per cent of total cultivated area with 43 per cent of rural families living below poverty line posing major problem for environmental protection and resource management. Concepts of sustainable development at regional-level planning suggested that there is a growing concern for the landscape community to develop a strategic regional agricultural planning perspective in order to assist landscape planning goals. These challenges were explored with particular reference to the cotton growing Yavatmal district in Maharashtra through baseline land resource / agronomic surveys and assessing the production potential of regional rural landscapes for crop planning. Landscape analysis, premised on the geopedological and elevation constructs, culminated in a spatial coverage of hills and ridges (12.6 per cent of total area in northern and central parts whereas plateaus (29.3 per cent in association with isolated hills, mesas and butte and escarpments (17.7 per cent, pediplains (28.8 per cent and plains (8.1 per cent in south western parts of the district. Regional level analysis revealed spatially variable soil typologies dominated by vertisols and vertic intergrades. An exploration and brief account of integration landscape planning was discussed with some reflections on the experience and highlighting some of the problems and potentials of this approach within the regional context.

    There is scant evidence describing antimicrobial (AM) usage in companion animal primary care veterinary practices in the UK. The use of AMs in dogs and cats was quantified using data extracted from 374 veterinary practices participating in VetCompass. The frequency and quantity of systemic antibiotic usage was described.Overall, 25 per cent of 963,463 dogs and 21 per cent of 594,812 cats seen at veterinary practices received at least one AM over a two-year period (2012-2014) and 42 per cent of these animals were given repeated AMs. The main agents used were aminopenicillin types and cephalosporins. Of the AM events, 60 per cent in dogs and 81 per cent in cats were AMs classified as critically important (CIAs) to human health by the World Health Organisation. CIAs of highest importance (fluoroquinolones, macrolides, third-generation cephalosporins) accounted for just over 6 per cent and 34 per cent of AMs in dogs and cats, respectively. The total quantity of AMs used within the study population was estimated to be 1473 kg for dogs and 58 kg for cats.This study has identified a high frequency of AM usage in companion animal practice and for certain agents classified as of critical importance in human medicine. The study highlights the usefulness of veterinary practice electronic health records for studying AM usage. British Veterinary Association.

    We present our experience with the amplification refractory mutation system (ARMS) for the prenatal diagnosis of beta-thalassaemia in 415 pregnancies of 360 women. Five mutations of the beta-thalassaemia gene common in Asian Indians accounted for 89.2 per cent and rare mutations for 7.2 per cent of all mutant chromosomes, while 3.3 per cent of chromosomes remained uncharacterized. Identical mutations were present in both parents in 43.2 per cent of cases, due to caste-based marriages in India. A confirmed diagnosis was given in 401 (98.3 per cent) cases, of which a complete diagnosis (whether the fetus was normal, a carrier, or homozygous) was possible in 391 (94.2 per cent) of the cases. In 15 couples, the mutation was identified in only one parent. In nine of these, the identified mutation was not present in the fetus, predicting normal/carrier status, while in five the identified mutation was present in the fetus, suggesting carrier/affected status. The abortion rate was 3.9 per cent. Pitfalls in diagnosis were failure of oligonucleotides to work, maternal contamination, and false paternity. The ARMS provides an inexpensive, robust and non-isotopic method for the prenatal diagnosis of beta-thalassaemia in India. Recommendations are outlined for establishing a prenatal diagnostic service in developing countries.

    2002-01-01

    The objective of the presented statistics is to give a total picture of the Swedish energy supply and its development. The efficiency of the final consumption is not considered in the balance sheets. The quantities (recalculated to tera joules = 10 12 joules) as reported under final consumption refer only to the total energy delivered to the consumers. The final consumption of energy in Sweden the 4th quarter 2001 increased by 5 per cent compared to the corresponding period 2000. The rise can be explained with the fact that the 4th quarter 2001 was colder compared with the same quarter 2000. The consumption within industrial sector was unchanged although the consumption within transports diminished. During the year 2001 energy consumption was unchanged compared with the year 2000. The consumption in household and service sector rose by 8 per cent. The highest rise can be find in the use of district heating and domestic fuels. The industry sector used 5 per cent less energy and mainly in the use of electric energy and domestic fuels. The gross supply of energy in Sweden the 4th quarter increased by 3,5 per cent compared to the 4th quarter 2000. The production of electricity from nuclear plants was 23 per cent higher compared with the same quarter 2000. Hydro-electric power production decreased by 4 per cent during the same period. The supply of natural gas rose by 24 per cent and the supply of domestic fuels rose by 4 %, the supply of coal and coke increased by 3 per cent and the same increase occurred in the supply of oil products. The gross supply of energy was 3 per cent higher during 2001 compared with 2000. The increase can be seen in the supply of coal and coke, 7 per cent, natural gas, 15 per cent, and production of electric energy in nuclear plants, 26 per cent. The balance sheets give both the total flow of various sources of energy and specifications of conversion and consumption in the energy producing industries. The contents of the balance sheets are

    Background & objectives: Surveillance of risk factors is important to plan suitable control measures for non-communicable diseases (NCDs). The objective of this study was to assess the behavioural, physical and biochemical risk factors for NCDs in Vellore Corporation and Kaniyambadi, a rural block in Vellore district, Tamil Nadu, India. Methods: This cross-sectional study was carried out among 6196 adults aged 30-64 yr, with 3799 participants from rural and 2397 from urban areas. The World Health Organization-STEPS method was used to record behavioural risk factors, anthropometry, blood pressure, fasting blood glucose and lipid profile. Multiple logistic regression was used to assess associations between risk factors. Results: The proportion of tobacco users (current smoking or daily use of smokeless tobacco) was 23 per cent in the rural sample and 18 per cent in the urban, with rates of smoking being similar. Ever consumption of alcohol was 62 per cent among rural men and 42 per cent among urban men. Low physical activity was seen among 63 per cent of the urban and 43 per cent of the rural sample. Consumption of fruits and vegetables was equally poor in both. In the urban sample, 54 per cent were overweight, 29 per cent had hypertension and 24 per cent diabetes as compared to 31, 17 and 11 per cent, respectively, in the rural sample. Physical inactivity was associated with hypertension, body mass index (BMI) ≥25 kg/m2, central obesity and dyslipidaemia after adjusting for other factors. Increasing age, male sex, BMI ≥25 kg/m2 and central obesity were independently associated with both hypertension and diabetes. Interpretation & conclusions: Diabetes, hypertension, dyslipidaemia, physical inactivity and overweight were higher in the urban area as compared to the rural area which had higher rates of smokeless tobacco use and alcohol consumption. Smoking and inadequate consumption of fruits and vegetables were equally prevalent in both the urban and rural samples

    to study whether an increase in intrapartum referrals in primary midwife-led care births in the Netherlands is accompanied by an increase in caesarean sections. nationwide descriptive study. the Netherlands Perinatal Registry. 789,795 births of nine year cohorts of women with low risk pregnancies in primary midwife-led care at the onset of labour between 2000 and 2008. primary outcome is the caesarean section rate. Vaginal instrumental delivery, augmentation with oxytocin, and pharmacological pain relief are secondary outcomes. Trends in outcomes are described. We used logistic regression to explore whether changes in the planned place of birth and other maternal characteristics influenced the caesarean section rate. the caesarean section rate did not increase and was 5.5 per cent (range 4.9-6.3 per cent) for nulliparous women, and 1.0 per cent (range 0.8-1.1 per cent) for multiparous women. After controlling for the decline in planned home births and other maternal characteristics no increase in the caesarean section rate was found. The vaginal instrumental birth rate showed no increase, and was 18.1 per cent (range 17.9-18.5 per cent) for nulliparous women and 1.5 per cent (range 1.4-1.7 per cent) for multiparous women. Augmentation of labour and/or pharmacological pain relief increased from 24.0 to 38.8 per cent for nulliparous women, and from 5.4 to 10.0 per cent for multiparous women. the rise in intrapartum referrals was not accompanied by an increase in caesarean section rate over the period 2000-2008. Despite a considerable rise in the use of pain relief and augmentation, the rate of spontaneous vaginal birth remained high for low risk women who started labour in primary midwife-led care. the current strict role division between primary care midwives and the obstetrician-led team increasingly results in a change in care provider during labour. In a more integrated care system, more women can receive continuous support of labour from their own primary care

    To report the prevalence and causes of visual impairment in seven-year-old children in Iran and its relationship with socio-economic conditions. In a cross-sectional population-based study, first-grade students in the primary schools of eight cities in the country were randomly selected from different geographic locations using multistage cluster sampling. The examinations included visual acuity measurement, ocular motility evaluation, and cycloplegic and non-cycloplegic refraction. Using the definitions of the World Health Organization (presenting visual acuity less than or equal to 6/18 in the better eye) to estimate the prevalence of vision impairment, the present study reported presenting visual impairment in seven-year-old children. Of 4,614 selected students, 4,106 students participated in the study (response rate 89 per cent), of whom 2,127 (51.8 per cent) were male. The prevalence of visual impairment according to a visual acuity of 6/18 was 0.341 per cent (95 per cent confidence interval 0.187-0.571); 1.34 per cent (95 per cent confidence interval 1.011-1.74) of children had visual impairment according to a visual acuity of 6/18 in at least one eye. Sixty-six (1.6 per cent) and 23 (0.24 per cent) children had visual impairment according to a visual acuity of 6/12 in the worse and better eye, respectively. The most common causes of visual impairment were refractive errors (81.8 per cent) and amblyopia (14.5 per cent). Among different types of refractive errors, astigmatism was the main refractive error leading to visual impairment. According to the concentration index, the distribution of visual impairment in children from low-income families was higher. This study revealed a high prevalence of visual impairment in a representative sample of seven-year-old Iranian children. Astigmatism and amblyopia were the most common causes of visual impairment. The distribution of visual impairment was higher in children from low-income families. Cost

    Total body surface area (TBSA) burned is a powerful descriptor of burn severity and influences the volume of resuscitation required in burn patients. The incidence and severity of TBSA overestimation by referring institutions (RIs) in children transferred to a burn center (BC) are unclear. The association between TBSA overestimation and overresuscitation is unknown as is that between TBSA overestimation and outcome. The trauma registry at a BC was queried over 7.25 years for children presenting with burns. TBSA estimate at RIs and BC, total fluid volume given before arrival at a BC, demographic variables, and clinical variables were reviewed. Nearly 20 per cent of children arrived from RIs without TBSA estimation. Nearly 50 per cent were overestimated by 5 per cent or greater TBSA and burn sizes were overestimated by up to 44 per cent TBSA. Average TBSA measured at BC was 9.5 ± 8.3 per cent compared with 15.5 ± 11.8 per cent as measured at RIs (P < 0.0001). Burns between 10 and 19.9 per cent TBSA were overestimated most often and by the greatest amounts. There was a statistically significant relationship between overestimation of TBSA by 5 per cent or greater and overresuscitation by 10 mL/kg or greater (P = 0.02). No patient demographic or clinical factors were associated with TBSA overestimation. Education efforts aimed at emergency department physicians regarding the importance of always calculating TBSA as well as the mechanics of TBSA estimation and calculating resuscitation volume are needed. Further studies should evaluate the association of TBSA overestimation by RIs with adverse outcomes and complications in the burned child.

    Cystenosine, composed of Cysteine and Inosine, was given to the patients with malignant tumors during radiotherapy. As radiotherapy, lineac x-ray 60 Co-γ ray, and 4 MV-betatron were used. Except betatron, a daily dose of 200 to 250 rads was given four times a week, and a total dose reached 5000 to 6000 rads. Administration of Cystenosine was started simultaneously with the onset of the radiotherapy, and 6 tablets a day were given. Of 40 subjects, the drug was very effective in 45 per cents, effective in 37.5 per cents, and ineffective in 17.5 per cents. The effective rate was 82.5 per cents, if the cases with effective and very effective were considered as effective. Of the patients, in whom irradiation field was larger than 15 x 15 cm, the drug was effective in 67 per cents and ineffective in 33 per cents. On the other hand, it was effective in 95 per cents of the patients, in whom irradiation field was middle or small and the size was under above size. Carcinostatic substances were concomitantly given to many of the patients, in whom malignant lymphoma and breast cancer were metastasized in a large extent. In 7 of 9 patients (77.8 per cents), hematopoietic disturbances were inhibited, and prearranged courses of therapy were effectively completed. Although the variation of the number of the blood platelets was not always parallel to that of leukocytes, interruption of the treatment because of the decrease of the blood platelets was found in none of the patients. Neither subjective not objective side effects were seen after the administration of Cystenosine. (Kumagai, S.)

    Optometry is a primary health-care profession (PHCP) and this study aimed to elucidate the factors influencing the choice of optometry as a career for Saudi students, the students' perceptions of optometry and the effect of gender. Two hundred and forty-seven students whose average age was 21.7 ± 1.5 (SD) years and who are currently enrolled in two colleges of optometry in Saudi Arabia--King Saud University (KSU) and Qassim University (QU)--completed self-administered questionnaires. The survey included questions concerning demography, career first choice, career perception and factors influencing career choices. The response rate was 87.6 per cent and there were 161 male (64.9 per cent) students. Seventy-nine per cent of the participants were from KSU (males and females) and 20.6 per cent were from QU (only males). Seventy-three per cent come from Riyadh and 19 per cent are from Qassim province. Regarding the first choice for their careers, the females (92 per cent) were 0.4 times more likely (p = 0.012) to choose optometry than males (78.3 per cent). The males were significantly more likely to be influenced by the following factors: the Doctor of Optometry (OD) programs run at both universities, good salary and prospects (p optometry. Females were more likely to opt for a career in optometry and males were more likely to be influenced by the new OD programs, good salary and job prospects. Service provision to others in the community was a primary motivation to opt for a career in optometry among young Saudis. © 2014 The Authors.

    A study was conducted to quantify and classify the waste generated at the National Refinery Limited (NRL). This refinery, located in Karachi, Pakistan, produces naphtha, motor gasoline, diesel, kerosene and lubricating oils and much more. Various units such as crude oil storage, thermal cracking, catalytic cracking and others were surveyed to assess the source and nature of the pollution. It was found that the major contributor to air pollution was the sulfur released through the burning of fuel oil during day-to-day operations. It was determined that approximately 2000 metric tons of solid waste were produced each day, along with 0.55 million gallons of waste water. In addition, sulfur, carbon dioxide, carbon monoxide and nitrogen dioxide were also released in the atmosphere. The solid waste was composed of municipal waste, sludges from the API and other discarded materials. The authors then proceeded to determine the heavy metals contents in samples obtained from combined sludge dumping areas on the premises. The sludges contained sulfur (0-1.26 wt per cent), lead (0-0.156 wt per cent), iron (0.01-3.4 wt per cent), chromium (0-0.159 per cent), copper (0-0.05 wt per cent), cadmium (0-0.0034 wt per cent), nickel (0-0.168 wt per cent), and manganese (0.0015-0.0776 wt per cent). It was recommended that hazardous and non-hazardous wastes be segregated, that a separate feasibility study be undertaken to determine the best possible course of action to dispose of solid waste, and that government guidelines be established on the same topic. 5 refs., 4 tabs.

    Increased globalisation and climate change have led to concern about the increasing risk of arthropod-borne virus (arbovirus) outbreaks globally. An outbreak of equine arboviral disease in northern Europe could impact significantly on equine welfare, and result in economic losses. Early identification of arboviral disease by horse owners may help limit disease spread. In order to determine what horse owners understand about arboviral diseases of horses and their vectors, the authors undertook an open, cross-sectional online survey of UK horse owners. The questionnaire was distributed using social media and a press release and was active between May and July 2016. There were 466 respondents, of whom 327 completed the survey in full. High proportions of respondents correctly identified photographic images of biting midges (71.2 per cent) and mosquitoes (65.4 per cent), yet few were aware that they transmit equine infectious diseases (31.4 per cent and 35.9 per cent, respectively). Of the total number of respondents, only 7.4 per cent and 16.2 per cent correctly named a disease transmitted by biting midges and mosquitoes, respectively. Only 13.1 per cent and 12.5 per cent of participants identified specific clinical signs of African horse sickness (AHS) and West Nile virus (WNV), respectively. This study demonstrates that in the event of heightened disease risk educational campaigns directed towards horse owners need to be implemented, focussing on disease awareness, clinical signs and effective disease prevention strategies. © British Veterinary Association (unless otherwise stated in the text of the article) 2018.

    The purpose of this paper is to examine an audit that was performed of all patients referred to a liaison psychiatry inpatient consultation service which sought to establish a baseline for demographics, type of referral, and management of referrals, with a view to introducing improved evidence-based treatments. It also aims to examine timeliness of response to referrals benchmarked against published standards. All inpatient referrals to a liaison psychiatry service were recorded over a six-month period, including demographics, diagnosis, management and timeliness of response to referrals. The data were retrospectively analysed and compared against international standards. A total of 172 referrals were received in the six months. Commonest referral reasons included assessments regarding depressive disorders (23.8 per cent), delirium/other cognitive disorders (19.2 per cent), alcohol-related disorders (18.6 per cent), anxiety disorders (14.5 per cent), and risk management (12.2 per cent). Evidence-based practices were not utilised effectively for a number of different types of presentations. A total of 40.1 per cent of referrals were seen on the same day, 75.4 per cent by the end of the next day, and 93.4 per cent by the end of the following day. Use of a hospital protocol for management of delirium may improve outcomes for these patients. Evidence-based techniques, such as brief intervention therapies, may be beneficial for referrals involving alcohol dependence. Referrals were seen reasonably quickly, but there is room for improvement when compared with published standards. This paper provides valuable information for those involved in management of liaison psychiatry consultation services, providing ideas for development and implementation of evidence based practices.

    A one-week smoking awareness initiative and subsequent audit in a general practice are described. All patients attending morning surgery during the study period were offered the opportunity to discuss smoking habits at a smoking awareness clinic: 84 smokers attended. They were interviewed by the practice preventive care nurse who took a smoking history, monitored carbon monoxide (CO Hb) levels and offered a follow-up appointment. CO Hb provided immediate feedback on the effect of smoking and patients who smoked 20 or more cigarettes per day had an average CO Hb of 16.1 per cent. Fifteen per cent of smokers made a commitment to stop smoking and agreed to attend follow-up clinics. A random sample (50) of attenders at the initial Smoking Awareness Clinic (84) were followed up by questionnaire six months later. There were 29 replies (58 per cent); 19 patients (65 per cent) found the visit to the clinic helpful, 14 (48 per cent) reduced the number of cigarettes they smoked, and 11 (38 per cent) altered some other aspect of their lifestyle, of whom four modified their diet and four increased exercise. Five patients claimed they had given up smoking.
