  1. Champagne Heat Pump

    The term champagne heat pump denotes a developmental heat pump that exploits a cycle of absorption and desorption of carbon dioxide in an alcohol or other organic liquid. Whereas most heat pumps in common use in the United States are energized by mechanical compression, the champagne heat pump is energized by heating. The concept of heat pumps based on other absorption cycles energized by heat has been understood for years, but some of these heat pumps are outlawed in many areas because of the potential hazards posed by leakage of working fluids. For example, in the case of the water/ammonia cycle, there are potential hazards of toxicity and flammability. The organic-liquid/carbon dioxide absorption/desorption cycle of the champagne heat pump is similar to the water/ammonia cycle, but carbon dioxide is nontoxic and environmentally benign, and one can choose an alcohol or other organic liquid that is also relatively nontoxic and environmentally benign. Two candidate nonalcohol organic liquids are isobutyl acetate and amyl acetate. Although alcohols and many other organic liquids are flammable, they present little or no flammability hazard in the champagne heat pump because only the nonflammable carbon dioxide component of the refrigerant mixture is circulated to the evaporator and condenser heat exchangers, which are the only components of the heat pump in direct contact with air in habitable spaces.

    This thesis will discuss the brand of champagne and its status as a luxury product. The aim is to find out how the luxury label might have affected the success of champagne and how it is marketed and branded. Champagne is one of the strongest brands in the wine industry throughout the history. It was branded already in the 19th century as the drink of the royals and today, is protected not by only the Comité Champagne, but also EU legislation. As a luxury product, champagne marketing rel...

    2016-04-01

    In a single glass of champagne about a million bubbles nucleate on the wall and rise towards the surface. When these bubbles reach the surface and rupture, they project a multitude of tiny droplets in the form of a particular aerosol holding a concentrate of wine aromas. Based on the model experiment of a single bubble bursting in idealized champagnes, the key features of the champagne aerosol are identified. In particular, we show that film drops, critical in sea spray for example, are here nonexistent. We then demonstrate that compared to a still wine, champagne fizz drastically enhances the transfer of liquid into the atmosphere. There, conditions on bubble radius and wine viscosity that optimize aerosol evaporation are provided. These results pave the way towards the fine tuning of flavor release during sparkling wine tasting, a major issue for the sparkling wine industry.

    Bubbles in a glass of champagne may seem like the acme of frivolity to most of people, but in fact they may rather be considered as a fantastic playground for any physicist. Actually, the so-called effervescence process, which enlivens champagne and sparkling wines tasting, is the result of the fine interplay between CO2 dissolved gas molecules, tiny air pockets trapped within microscopic particles during the pouring process, and some both glass and liquid properties. Results obtained concerning the various steps where the CO2 molecule plays a role (from its ingestion in the liquid phase during the fermentation process to its progressive release in the headspace above the tasting glass as bubbles collapse) are gathered and synthesized to propose a self-consistent and global overview of how gaseous and dissolved CO2 impact champagne and sparkling wine science. Physicochemical processes behind the nucleation, rise, and burst of gaseous CO2 bubbles found in glasses poured with champagne and sparkling wines are depicted. Those phenomena observed in close-up through high-speed photography are often visually appealing. I hope that your enjoyment of champagne will be enhanced after reading this fully illustrated review dedicated to the science hidden right under your nose each time you enjoy a glass of champagne.

    Full Text Available Sparkling wine represents a small but significant proportion of the Australian wine industry’s total production. Yet, Australia remains a significant importer of French Champagne. This study investigated consumer preferences for Australian sparkling wine vs. French Champagne and any compositional and/or sensorial bases for these preferences. A range of French and Australian sparkling wines were analyzed by MIR spectroscopy to determine if sparkling wines could be differentiated according to country of origin. A subset of wines, comprising two French Champagnes, a French sparkling wine and three Australian sparkling wines, were selected for (i descriptive analysis to characterize their sensory profiles and (ii acceptance tests to determine consumer liking (n = 95 Australian wine consumers. Significant differences were observed between liking scores; on average, the $70 French Champagne was liked least and the $12 Australian sparkling wine liked most, but segmentation (based on individual liking scores identified clusters comprising consumers with distinct wine preferences. Interestingly, when consumers were shown wine bottle labels, they considered French wines to be more expensive than Australian wines, demonstrating a clear country of origin influence.

    Under standard champagne tasting conditions, the complex interplay between the level of dissolved CO2 found in champagne, its temperature, the glass shape, and the bubbling rate definitely impacts champagne tasting by modifying the neuro-physicochemical mechanisms responsible for aroma release and flavor perception. On the basis of theoretical principles combining heterogeneous bubble nucleation, ascending bubble dynamics, and mass transfer equations, a global model is proposed, depending on various parameters of both the wine and the glass itself, which quantitatively provides the progressive losses of dissolved CO2 from laser-etched champagne glasses. The question of champagne temperature was closely examined, and its role on the modeled losses of dissolved CO2 was corroborated by a set of experimental data. PMID:27031022

    The champagne bottle neck (CBN) sign refers to a reduction in the diameter of the proximal portion of the internal carotid artery that resembles a CBN, and is a characteristic feature of Moyamoya disease. A 43-year-old woman with an infarction of the posterior limb of the left internal capsule was diagnosed with Moyamoya syndrome associated with Graves' disease. The CBN sign was observed bilaterally. Cerebral revascularization surgery was performed, including left-sided superficial temporal artery to middle cerebral artery anastomosis. During four years of follow-up, she maintained a euthyroid state and did not have any further cerebral ischemic events. The CBN signs remained unchanged on both sides during this time. This is the first report of the CBN sign in a patient with Moyamoya syndrome associated with Graves' disease. PMID:25232554

    The well-known Generalized Champagne Problem on simultaneous stabilization of linear systems is solved by using complex analysis and Blondel's technique. We give a complete answer to the open problem proposed by Patel et al., which automatically includes the solution to the original Champagne Problem. Based on the recent development in automated inequality-type theorem proving, a new stabilizing controller design method is established. Our numerical examples significantly improve the relevant results in the literature.

    Full Text Available Champagne coat color in horses is controlled by a single, autosomal-dominant gene (CH. The phenotype produced by this gene is valued by many horse breeders, but can be difficult to distinguish from the effect produced by the Cream coat color dilution gene (CR. Three sires and their families segregating for CH were tested by genome scanning with microsatellite markers. The CH gene was mapped within a 6 cM region on horse chromosome 14 (LOD = 11.74 for theta = 0.00. Four candidate genes were identified within the region, namely SPARC [Secreted protein, acidic, cysteine-rich (osteonectin], SLC36A1 (Solute Carrier 36 family A1, SLC36A2 (Solute Carrier 36 family A2, and SLC36A3 (Solute Carrier 36 family A3. SLC36A3 was not expressed in skin tissue and therefore not considered further. The other three genes were sequenced in homozygotes for CH and homozygotes for the absence of the dilution allele (ch. SLC36A1 had a nucleotide substitution in exon 2 for horses with the champagne phenotype, which resulted in a transition from a threonine amino acid to an arginine amino acid (T63R. The association of the single nucleotide polymorphism (SNP with the champagne dilution phenotype was complete, as determined by the presence of the nucleotide variant among all 85 horses with the champagne dilution phenotype and its absence among all 97 horses without the champagne phenotype. This is the first description of a phenotype associated with the SLC36A1 gene.

  14. Sponge Cake or Champagne? Bubbles, Magmatic Degassing and Volcanic Eruptions

    Vesiculation is an unavoidable consequence of magma decompression; the extent to which bubbles travel with ascending magma or leave the system by separated or permeable flow will determine the nature of the ensuing eruption. Bubbles travel with the melt from which they exsolve if the rise time of bubbles through the melt (the 'drift velocity') is much less than the rise rate of the magma (sponge cake). This condition is most likely to be met in viscous melts (where bubble rise velocities are low) and in melts that experience rapid decompression (high ascent velocities). Under these conditions, bubble expansion within the melt continues until sufficient bubble expansion causes coalescence and the development of a permeable network. Typical pumice vesicularities of 70-80% and permeabilities of 10-12 m2 constrain this limit under conditions appropriate for subplinian to plinian eruptions (mass fluxes > 106 kg/s). Slower rise rates (and lower mass fluxes) that characterize effusive eruptions produce silicic lavas with a wider range of vesicularities. In general, permeability decreases with decreasing sample vesicularity as bubbles deform (as evidenced by anisotropy in permeability and electrical conductivity) and pore apertures diminish. Degassing efficiency (and resulting densification of magma within the conduit) under these conditions is determined by permeability and the time allowed for gas escape. Bubbles rise through the melt if the drift velocity exceeds the velocity of magma ascent (champagne). This condition is most easily met in volatile-rich, low viscosity (mafic) melts at low to moderate fluxes. At very low magma flux, magma eruption rate is determined by the extent to which magma is entrained and ejected by rising gases (strombolian eruptions); when bubbles are too small, or are rising too slowly, they may not break the surface at all, but instead may be concentrated in a near-surface layer (surface foam). As the magma flux increases, segregation of

    Methods to measure low concentrations of tritium and radiocarbon in wine and champagne, respectively, have been tested by using liquid scintillation counting after chemical sample processing. It could be shown that tritium activity was too low to be measured by our standard low-level liquid scintillation counter, WALLAC Guardian 1414. Positive results could be achieved when using a WALLAC Quantulus. The methods will be established as standard methods to detect forgeries and to improve consumer safety.

    People have long been fascinated by bubbles and foams dynamics, and since the pioneering work of Leonardo da Vinci in the early 16th century, this subject has generated a huge bibliography. However, only very recently, much interest was devoted to bubbles in Champagne wines. Small bubbles rising through the liquid, as well as a bubble ring (the so-called collar) at the periphery of a flute poured with champagne are the hallmark of this traditionally festive wine, and even there is no scientific evidence yet to connect the quality of a champagne with its effervescence, people nevertheless often make a connection between them. Therefore, since the last few years, a better understanding of the numerous parameters involved in the bubbling process has become an important stake in the champagne research area. Otherwise, in addition to these strictly enological reasons, we also feel that the area of bubble dynamics could benefit from the simple but close observation of a glass poured with champagne. In this study, our first results concerning the close observation of the three main steps of a champagne bubble's life are presented, that is, the bubble nucleation on tiny particles stuck on the glass wall (Chap. 2), the bubble ascent through the liquid (Chap. 3), and the bursting of bubbles at the free surface, which constitutes the most intriguing and visually appealing step (Chap. 4). Our results were obtained in real consuming conditions, that is, in a classical crystal flute poured with a standard commercial champagne wine. Champagne bubble nucleation proved to be a fantastic everyday example to illustrate the non-classical heterogeneous bubble nucleation process in a weakly supersaturated liquid. Contrary to a generally accepted idea, nucleation sites are not located on irregularities of the glass itself. Most of nucleation sites are located on tiny hollow and roughly cylindrical exogenous fibres coming from the surrounding air or remaining from the wiping process

    People have long been fascinated by bubbles and foams dynamics, and since the pioneering work of Leonardo da Vinci in the early 16th century, this subject has generated a huge bibliography. However, only quite recently, much interest was devoted to bubbles in Champagne wines and carbonated beverages. Since the time of the benedictine monk dom Pierre Perignon (1638-1715), champagne is the wine of celebration. This fame is largely linked to the elegance of its effervescence and foaming properties. In this book, the latest results about the chemical physics behind the bubbling properties of Champagne and sparkling wines are collected and fully illustrated. The first chapter is devoted to the history of champagne and to a presentation of the tools of the physical chemistry of interfaces needed for a whole comprehension of the book. Then, the three main steps of a fleeting champagne bubble's life are presented in chronological order, that is, the bubble nucleation on the glass wall (Chap.2), the bubble ascent and growth through the liquid matrix (Chap.3), and the bursting of bubbles at the liquid surface (Chap.4), which constitutes the most intriguing, functional, and visually appealing step. L'objectif général de ce travail consacré à l'étude des processus physicochimiques liés à l'effervescence des vins de Champagne était de décortiquer les différentes étapes de la vie d'une bulle de champagne en conditions réelles de consommation, dans une flûte.

    Archaeochemistry as the application of the most recent analytical techniques to ancient samples now provides an unprecedented understanding of human culture throughout history. In this paper, we report on a multiplatform analytical investigation of 170-y-old champagne bottles found in a shipwreck at the bottom of the Baltic Sea, which provides insight into winemaking practices used at the time. Organic spectroscopy-based nontargeted metabolomics and metallomics give access to the detailed composition of these wines, revealing, for instance, unexpected chemical characteristics in terms of small ion, sugar, and acid contents as well as markers of barrel aging and Maillard reaction products. The distinct aroma composition of these ancient champagne samples, first revealed during tasting sessions, was later confirmed using state-of-the-art aroma analysis techniques. After 170 y of deep sea aging in close-to-perfect conditions, these sleeping champagne bottles awoke to tell us a chapter of the story of winemaking and to reveal their extraordinary archaeometabolome and elemental diversity in the form of chemical signatures related to each individual step of champagne production.

  20. Monitoring gaseous CO2 and ethanol above champagne glasses: flute versus coupe, and the role of temperature.

    Directory of Open Access Journals (Sweden)

    Gérard Liger-Belair

    Full Text Available In champagne tasting, gaseous CO(2 and volatile organic compounds progressively invade the headspace above glasses, thus progressively modifying the chemical space perceived by the consumer. Simultaneous quantification of gaseous CO(2 and ethanol was monitored through micro-gas chromatography (μGC, all along the first 15 minutes following pouring, depending on whether a volume of 100 mL of champagne was served into a flute or into a coupe. The concentration of gaseous CO(2 was found to be significantly higher above the flute than above the coupe. Moreover, a recently developed gaseous CO(2 visualization technique based on infrared imaging was performed, thus confirming this tendency. The influence of champagne temperature was also tested. As could have been expected, lowering the temperature of champagne was found to decrease ethanol vapor concentrations in the headspace of a glass. Nevertheless, and quite surprisingly, this temperature decrease had no impact on the level of gaseous CO(2 found above the glass. Those results were discussed on the basis of a multiparameter model which describes fluxes of gaseous CO(2 escaping the liquid phase into the form of bubbles.

  1. Perception of the nuclear industry by general practitioner in Champagne-Ardennes (France)

    International Nuclear Information System (INIS)

    In the case of a nuclear accident, the general practitioners should be the relay in the population information. In order to confront their knowledge and sensitivity with the nuclear industry problems, the authors have conducted an inquiry near to 144 general practitioners in Champagne-Ardennes area, in the immediate neighbourhood of nuclear facilities (CHOOZ, Nogent-sur-Seine, Gravelines) or not. Four subjects are studied: -their perception of the nuclear industry in the environment problems - their knowledge in nuclear physics - their knowledge about the nuclear power plant - their attitude in front of a radiation accident. The authors show that their education and knowledges about the nuclear industry is insufficient and propose several solutions in order to cope with these difficulties

  2. Champagne Flutes and Brandy Snifters: Modelling Protostellar Outflow-Cloud Chemical Interfaces

    Rollins, Richard P; Williams, David A; Redman, Matt P

    2014-01-01

    A rich variety of molecular species has now been observed towards hot cores in star forming regions and in the interstellar medium. An increasing body of evidence from millimetre interferometers suggests that many of these form at the interface between protostellar outflows and their natal molecular clouds. However, current models have remained unable to explain the origin of the observational bias towards wide-angled "brandy snifter" shaped outflows over narrower "champagne flute" shapes in carbon monoxide imaging. Furthermore, these wide-angled systems exhibit unusually high abundances of the molecular ion HCO$^+$. We present results from a chemo-dynamic model of such regions where a rich chemistry arises naturally as a result of turbulent mixing between cold, dense molecular gas and the hot, ionized outflow material. The injecta drives a rich and rapid ion-neutral chemistry in qualitative and quantitative agreement with the observations. The observational bias towards wide-angled outflows is explained natu...

    Five different methodologies were applied for the quantitative analysis of 86 volatile molecules in 32 Chardonnay and 30 Pinot Noir Champagne white base wines. Sensory characterization was carried out by descriptive analysis. Pinot Noir wines had more constitutive compounds while Chardonnay wines had more discriminant compounds. Only four compounds predominated in Chardonnay wines: 4-vinylphenol, guaiacol, sotolon and 4-methyl-4-mercapto-2-pentanone. Correlation studies and PLSR models were calculated with sensory and chemical variables. For Pinot Noir wines, they were not as revealing as for Chardonnay base wines. Sulfur-related compounds were suggested to be involved in tropical fruit, dried fruit and citric sensory notes. This family of compounds seemed to be responsible for discriminant sensory terms in Champagne base wines. Fermentative compounds (aromatic buffer) were found at significantly higher levels in Pinot Noir wines, which would explain the fact that these wines were more difficult to describe in comparison with Chardonnay base wines.

    Full Text Available Acid-sulfide hot springs are analogs of early Earth geothermal systems where microbial metal(loid resistance likely first evolved. Arsenic is a metalloid enriched in the acid-sulfide hot spring Champagne Pool (Waiotapu, New Zealand. Arsenic speciation in Champagne Pool follows reaction paths not yet fully understood with respect to biotic contributions and coupling to biogeochemical sulfur cycling. Here we present quantitative arsenic speciation from Champagne Pool, finding arsenite dominant in the pool, rim and outflow channel (55-75% total arsenic, and dithio- and trithioarsenates ubiquitously present as 18-25% total arsenic. In the outflow channel, dimethylmonothioarsenate comprised ≤9% total arsenic, while on the outflow terrace thioarsenates were present at 55% total arsenic. We also quantified sulfide, thiosulfate, sulfate and elemental sulfur, finding sulfide and sulfate as major species in the pool and outflow terrace, respectively. Elemental sulfur reached a maximum at the terrace. Phylogenetic analysis of 16S rRNA genes from metagenomic sequencing revealed the dominance of Sulfurihydrogenibium at all sites and an increased archaeal population at the rim and outflow channel. Several phylotypes were found closely related to known sulfur- and sulfide-oxidizers, as well as sulfur- and sulfate-reducers. Bioinformatic analysis revealed genes underpinning sulfur redox transformations, consistent with sulfur speciation data, and illustrating a microbial role in sulfur-dependent transformation of arsenite to thioarsenate. Metagenomic analysis also revealed genes encoding for arsenate reductase at all sites, reflecting the ubiquity of thioarsenate and a need for microbial arsenate resistance despite anoxic conditions. Absence of the arsenite oxidase gene, aio, at all sites suggests prioritization of arsenite detoxification over coupling to energy conservation. Finally, detection of methyl arsenic in the outflow channel, in conjunction with

    In France, universal newborn hearing screening has been mandatory since April23rd, 2012, but it began in the Champagne-Ardenne region on January 15th 2004. More than 99 % of 160 196 newborns have since been systematically screened in this region. Bilateral hearing impairment was thus identified in 116 infants when they were around 3.5 months old. Earlier diagnosis improves the outcome of deafness, which is only diagnosed around age 20 months without screening. The authors report their experience and the lessons learnt.

  6. HIGHLIGHTS OF ROMANIAN AND FRENCH WINE MARKETS: THE EXAMPLE OF FRENCH CHAMPAGNE MARKET

    Directory of Open Access Journals (Sweden)

    Jubenot Marie-Noelle

    2014-12-01

    Full Text Available The market is a dynamic market in which the European Union plays a leading role as the main producer and exporter of vine products. In this area, four countries with strong agricultural and viticultural tradition dominate the market: France, Italy, Spain and Germany. But among the new eastern EU members, countries as Romania, with a favorable geography and climate and also a viticultural tradition, some may also play a more prominent role. Romania is part of the top 12 wine-producing countries, however Romania penalty to export large-scale production of wine. In contrast, France is the main producer and exporter of wine country. This situation is primarily due to the strategic choice of a very strong geographic labelisation of wine production and the emphasis on quality and even the excellence of its products, in particular thanks to a promotion policy. Two major non-exclusive solutions seem to emerge for Romania. On the one hand, it can copy to a certain extent the French solution by leveraging labelisation its wines. The French wine market is also the reference of the European Union in particular as regards the creation of the label: Appellation of Origin (PDO. The example of champagne is, in this context, remarkable. This product alone largely not only the volume and value of exports of wines, but also the volume and value of exports of all agricultural products. It can also try to increase its exports to emerging countries outside the European Union. Non-European areas are both a promise of growing opportunities in a context of economic crisis or post-crises and a threat to the European wine sector: in particular we think about America, Asia and Oceania. Indeed, the main third countries also wine producers are trying to increase their market share. This explains the new measures taken by the European authorities aimed at deep modernizing European wine sector.

The minimally processed oranges were stored at 5 ± 1°C for 8 days and were subjected to physicochemical and microbiological analyses every two days. Greater weight loss occurred in fruits without flavedo and segmented, uncoated, and coated with the edible gelatin film During storage, there was a slight increase in Total Soluble Solids (TSS for the treatments with greater weight loss and reduction in acidity and ascorbic acid, regardless of the packaging type. The microbial counts did not exceed the acceptable limits in the treatments; however, higher counts were observed at the end of storage. The minimally processed fruit packed in lidded polystyrene containers and polyethylene and PVC films kept their overall fresh visual appearance with a few physicochemical and microbiological changes up to the 8th day of storage.

  9. Uranium series geochemistry in aquifers: quantification of transport mechanisms of uranium and daughter products: the chalk aquifer (Champagne, France)

    International Nuclear Information System (INIS)

    With the increase of contaminant flux of radionuclides in surface environment (soil, river, aquifer...), there is a need to understand and model the processes that control the distribution of uranium and its daughter products during transport within aquifers. We have used U-series disequilibria as an analogue for the transport of uranium and its daughter products in aquifer to understand such mechanisms. The measurements of uranium (234U et 238U), thorium (230Th et 232Th), 226Ra and 222Rn isotopes in the solid and liquid phases of the chalk aquifer in Champagne (East of France) allows us to understand the processes responsible for fractionation within the uranium decay chain. Fractionations are induced by physical and chemical properties of the elements (leaching, adsorption) but also by radioactive properties (recoil effect during α-decay). For the first time a comprehensive sampling of the solid phase has been performed, allowing quantifying mechanisms responsible for the long term evolution of the aquifer. A non steady state 1D model has been developed which takes into account leaching, adsorption processes as well as radioactive filiation and α-recoil effect. Retardation coefficients have been calculated for uranium, thorium and radium. The aquifer is characterised by a double porosity, and the contribution of fracture and matrix porosity on the water/rock interaction processes has been estimated. (author)

    Soil and Vitis vinifera L. (coarse and fine roots, leaves, berries) concentration and geochemical partitioning of Cu, Pb and Zn were determined in a contaminated calcareous Champagne plot to assess their mobility and transfer. Accumulation ratios in roots remained low (0.1-0.4 for Cu and Zn, <0.05 for Pb). Differences between elements resulted from vegetation uptake strategy and soil partitioning. Copper, significantly associated with the oxidisable fraction (27.8%), and Zn with the acid soluble fraction (33.3%), could be mobilised by rhizosphere acidification and oxidisation, unlike Pb, essentially contained in the reducible fraction (72.4%). Roots should not be considered as a whole since the more reactive fine roots showed higher accumulation ratios than coarse ones. More sensitive response of fine roots, lack of correlation between chemical extraction results and vegetation concentrations, and very limited translocation to aerial parts showed that fine root concentrations should be used when assessing bioavailability. - Soil Cu, Pb and Zn concentration and partitioning were combined to accumulation ratio to study the transfer of trace element from soil to Vitis vinifera L. roots and aerial parts in a contaminated vineyard plot.

  17. Biotinidase deficiency and our champagne legacy.

    Science.gov (United States)

    Wolf, Barry

    2016-09-10

    Biotinidase is the enzyme that is necessary for the recycling of the vitamin, biotin. Biotinidase deficiency is an autosomal recessively inherited metabolic disorder. If untreated, individuals with biotinidase deficiency usually develop neurological and cutaneous symptoms that can result in coma or death. Symptomatic individuals can be markedly improved by treating them with pharmacological doses of biotin; however, some clinical features may be irreversible. Fortunately, essentially all symptoms can be prevented if treatment is initiated at birth or before the symptoms develop. Because of this, the disorder is currently screened for in newborns in all states in the United States and in many countries around the world. This is the story of one laboratory's work in bringing basic science research from the discovery of the disorder to its translation into clinical medicine and its impact on the individuals with the disorder and their families.

    In 92,130 pregnancies followed between 1980 and 1987, 48 cases of hyperthyroidism were reported including 38 Grave's diseases, 5 toxic adenomas, 4 multinodules goiters. In comparing the results with those mentioned in the literature, a number of conclusions may be reached. In case of hyperthyroidism treated before the pregnancy or discovered at the beginning, there is, in every other case, an aggravation at the end of the first trimester, then a stabilization in the 2nd or 3rd trimester and finally an aggravation in the post-partum period. There is a high rate of abortions (35 p. cent), a delayed intra-uterine growth in half of the cases. The problem of the treatment is of paramount importance; there is no problem with Beta-blockers but the SAT are not without danger: risk of hypothyroidism and fetal goiter, but also risk of maternal hypothyroidism. From the 15th week, the doses should therefore be decreased, and sometimes the treatment discontinued and replaced with Beta-blockers. The best SAT drug during pregnancy is the propylthioracile which is the least likely to cross the fetal barrier. Surgery is only exceptionally indicated. In a woman who is cured from her Grave's disease, recurrences are always possible, and also fetal hyperthyroidism caused by crossing of thyreostimulins immunoglobins, even in case of maternal euthyroidism.

    Copper, a priority substance on the EU-Water Framework Directive list, is widely used to protect grapevines against fungus diseases. Many vineyards being located on steep slopes, large amounts of Cu could be discharged in downstream systems by runoff water. The efficiency of stormwater detention basins to retain copper in a vineyard catchment was estimated. Suspended solids, dissolved (Cu{sub diss}) and total Cu (Cu{sub tot}) concentrations were monitored in runoff water, upstream, into and downstream from a detention pond. Mean Cu{sub tot} concentrations in entering water was 53.6 mug/L whereas it never exceeded 2.4 mug/L in seepage. Cu{sub tot} concentrations in basin water (>100 mug/L in 24% of the samples) exceeded LC{sub 50} values for several aquatic animals. Copper was principally sequestered by reduced compounds in the basin sediments (2/3 of Cu{sub tot}). Metal sequestration was reversible since sediment resuspension resulted in Cu remobilization. Wind velocity controlled resuspension, explained 70% of Cu{sub diss} variability and could help predicting Cu mobilization. - Copper in stormwater basin is efficiently retained but can be released during windy events or after dredging.

    Full Text Available Water is a vehicle for disseminating human and veterinary toxoplasmosis due to oocyst contamination. Several outbreaks of toxoplasmosis throughout the world have been related to contaminated drinking water. We have developed a method for the detection of Toxoplasma gondii oocysts in water and we propose a strategy for the detection of multiple waterborne parasites, including Cryptosporidium spp. and Giardia. Water samples were filtered to recover Toxoplasma oocysts and, after the detection of Cryptosporidium oocysts and Giardia cysts by immunofluorescence, as recommended by French norm procedure NF T 90-455, the samples were purified on a sucrose density gradient. Detection of Toxoplasma was based on PCR amplification and mouse inoculation to determine the presence and infectivity of recovered oocysts. After experimental seeding assays, we determined that the PCR assay was more sensitive than the bioassay. This strategy was then applied to 482 environmental water samples collected since 2001. We detected Toxoplasma DNA in 37 environmental samples (7.7%, including public drinking water; however, none of them were positive by bioassay. This strategy efficiently detects Toxoplasma oocysts in water and may be suitable as a public health sentinel method. Alternative methods can be used in conjunction with this one to determine the infectivity of parasites that were detected by molecular methods.

    The observations of the Cassini spacecraft since 2004 revealed that Titan, the largest moon of Saturn, has an active climate cycle with a cloud cover related to the large scale atmospheric circulation, lakes of methane and hyrdrocarbons with variable depth, a dried fluvial system witnessing a past wetter climate, dunes, and deep changes in the weather and atmospheric structure as Titan went through the North Spring equinox. Moreover, the upper atmosphere is now considered the cradle of complex chemistry leading to aerosol formation, as well as the manifestation place of atmospheric waves. However, as the Cassini mission comes to its end, many fundamental questions remain unresolved... The objective of the workshop is to bring together international experts from different fields of Titan's research in order to have an overview of the current understanding, and to determine the remaining salient scientific issues and the actions that could be implemented to address them. PhD students and post-doc researchers are welcomed to present their studies. This conference aims to be a brainstorming event leaving abundant time for discussion during oral and poster presentations. Main Topics: - Atmospheric seasonal cycles and coupling with dynamics. - Composition and photochemistry of the atmosphere. - Formation and evolution of aerosols and their role in the atmosphere. - Spectroscopy, optical properties, and radiative transfer modeling of the atmosphere. - Surface composition, liquid reservoirs and interaction with atmosphere. - Evolution of the atmosphere. - Titan after Cassini, open questions and the path forward.

    We simulate evolution of cometary H II regions based on several champagne flow models and bow shock models, and calculate the profiles of the [Ne II] fine-structure line at $12.81\\mu m$, the $H30\\alpha$ recombination line and the [Ne III] fine-structure line at $15.55\\mu m$ for these models at different inclinations of $0^o, 30^o \\textrm{and} 60^o$. We find that the profiles in the bow shock models are generally different from those in the champagne flow models, but the profiles in the bow shock with lower stellar velocity ($\\leq5km s^{-1}$) are similar to those in the champagne flow models. In champagne flow models, both the velocity of peak flux and the flux weighted central velocities of all three lines are pointing outward from molecular clouds. In bow shock models, the directions of these velocities rely on the speed of stars. They have the similar motion in high stellar speed case but opposite directions in low stellar speed case. We notice that the line profiles from the slit along the symmetrical axis...

    We have developed a full numerical method to study the gas dynamics of cometary ultra-compact (UC) H II regions, and associated photodissociation regions (PDRs). The bow-shock and champagne-flow models with a $40.9/21.9 M_\\odot$ star are simulated. In the bow-shock models, the massive star is assumed to move through dense ($n=8000~cm^{-3}$) molecular material with a stellar velocity of $15~km~s^{-1}$. In the champagne-flow models, an exponential distribution of density with a scale height of 0.2 pc is assumed. The profiles of the [Ne II] 12.81\\mum and $H_2~S(2)$ lines from the ionized regions and PDRs are compared for two sets of models. In champagne-flow models, emission lines from the ionized gas clearly show the effect of acceleration along the direction toward the tail due to the density gradient. The kinematics of the molecular gas inside the dense shell is mainly due to the expansion of the H II region. However, in bow-shock models the ionized gas mainly moves in the same direction as the stellar motion...

    Pea (Pisum sativum) cell wall metabolism in response to chilling was investigated in a frost-sensitive genotype 'Terese' and a frost-tolerant genotype 'Champagne'. Cell walls isolated from stipules of cold acclimated and non-acclimated plants showed that cold temperatures induce changes in polymers containing xylose, arabinose, galactose and galacturonic acid residues. In the tolerant cultivar Champagne, acclimation is accompanied by increases in homogalacturonan, xylogalacturonan and highly branched Rhamnogalacturonan I with branched and unbranched (1→5)-α-arabinans and (1→4)-β-galactans. In contrast, the sensitive cultivar Terese accumulates substantial amounts of (1→4)-β-xylans and glucuronoxylan, but not the pectins. Greater JIM7 labeling was observed in Champagne compared to Terese, indicating that cold acclimation also induces an increase in the degree of methylesterification of pectins. Significant decrease in polygalacturonase activities in both genotypes were observed at the end of cold acclimation. These data indicate a role for esterified pectins in cold tolerance. The possible functions for pectins and their associated arabinans and galactans in cold acclimation are discussed.

    Human activities disrupt natural biogeochemical cycles such as the carbon and contribute to an increase in the concentrations of the greenhouse gases (carbone dioxide and methane) in the atmosphere. The current atmospheric transport modeling (the vertical trade) still represents an important source of uncertainty in the determination of regional flows of greenhouse gases, which means that a good knowledge of the vertical distribution of CO2 is necessary to (1) make the link between the ground measurements and spatial measurements that consider an integrated concentration over the entire column of the atmosphere, (2) validate and if possible improve CO2 transport model to make the link between surface emissions and observed concentration.

    Seike, Nahoko; Ito, Michiko; Yasaka, Masahiro

    2010-12-01

    Carotid stenosis is observed in several diseases such as atherosclerosis, moyamoya disease, and aortitis. Carotid stenosis can be assessed using computed tomography (CT), magnetic resonance angiography (MRA), ultrasonography, or cerebral angiography. Carotid ultrasonography is superior to other modalities because it is a noninvasive, repeatable, and easy method that does not involve much cost. The intima-media complex thickness (IMT) can be easily measured using carotid ultrasonography. The incidence of cerebral and cardiovascular events increases with increase in the thickness of the IMT. The percentage of stenosis was expressed using the NASCET, ECST, or area methods. The NASCET criterion of 70% stenosis for performing carotid endarterectomy for symptomatic carotid stenosis corresponded to 85% ECST stenosis, 90% area stenosis, and 200 cm/sec of peak systolic velocity. Carotid ultrasonography provides information on not only carotid stenosis but also unstable plaques such as ulcer, hypoechoic plaque, thin fibrous cap, and mobile plaque. In patients with moyamoya disease, carotid ultrasonography often reveals that the diameter of the internal carotid artery (ICA) is greatly reduced at the proximal portion above the bulbus (resembling a champagne bottle neck) and is less than 50% that of the common carotid artery (champagne bottle neck sign); the diameter of the ICA is smaller than that of the external carotid artery (diameter reversal sign). In patients with aortitis, IMT thickness is frequently observed at the common carotid artery (Macaroni sign) but not at the ICA. PMID:21139180

    The possible impacts of climate change at small spatial scales are still very little known. The knowledge of the climate risks at small scales is yet essential for agricultural activities and productions like vine growing, because of their serious economic impacts. Because of their relatively high latitude, the vineyards of the northern Half of France are subjected to spring frost, which can cause serious damages e.g. in the Champagne area on April the 8th, 2003. A detailed study of the variability and frequency of spring frost events in four vineyards (Loire Valley, Champagne, Burgundy and Alsace) was carried out within the framework of the RICLIM-CNRS 2663 multidisciplinary Research Group "Climate Risks" and was supported by the research program TERVICLIM (ANR-JC07-194103) and by the MAIF Foundation (program about air-mass circulation dynamics and climate risks). The northern Half of France is included in the Cfb type of climate (according to the Köppen's classification) of northwestern and central Europe. However, the combined effects of the latitude, the continentality and the topography involve varied regional climates. Among the four studied wine-producing areas, the Loire Valley area is the warmest, the Champagne area is the coolest in summer, and eastern Burgundy and especially Alsace are the most subjected to the continentality effect (highest annual temperature oscillation and highest rainfall amounts in summer). Therefore, these areas are not equally subjected to the frost risk. Spring is a key season for the vine growing and during frost-producing weather patterns, northern France is subjected to a high spatial variability of temperature at regional and local scales. During the period 1960-2007, the number of spring frost day events was three times as high in Colmar (Alsace) than in Saumur (Loire Valley). Among the four wine-producing areas, Alsace records the most hard and frequent frosts in early spring, while the Champagne area records the latest

    2003-05-01

    Full Text Available The European Common Agricultural Policy is shifting an increasing part of the subsidies to eco-conditionality. Henceforth, it becomes essential to evaluate the environmental effect of agricultural practices, and more generally performances of cropping and farming systems, in order to design and to develop more sustainable systems. This assessment is being implemented for the main cropping systems of some French regions, using environmental indicators. Eleven exposure indicators were chosen in order to represent a wide range of specific sustainability objectives dealing with water, soil, air, non-renewable resources, biodiversity, and landscape. The results present the sustainability assessment for the crop rotations of Champagne Berrichonne region in the Centre of France.

    Herd, Denise

    2014-02-01

    This study examines the prevalence and context of alcohol references in rap music lyrics from 1979 through 2009. Four hundred nine top-ranked rap music songs released were sampled from Billboard magazine rating charts. Songs were analyzed using systematic content analysis and were coded for alcohol beverage types and brand names, drinking behaviors, drinking contexts, attitudes towards alcohol, and consequences of drinking. Trends were analyzed using regression analyses. The results of the study reveal significant increases in the presence of alcohol in rap songs; a decline in negative attitudes towards alcohol; decreases in consequences attributed to alcohol; increases in the association of alcohol with glamour and wealth, drugs, and nightclubs; and increases in references to liquor and champagne.

    2010-09-01

    Full Text Available Apesar da grande produção de quartzo em Minas Gerais, pouco é conhecido sobre a influência do ambiente geológico na geração das variedades coloridas através de tratamento. Sabe-se que a irradiação gama, seguida ou não de aquecimento, conduz à formação de cores, tais como acontece com a ametista, prasiolita, green gold, beer, cognac, whisky e champagne. Amostras de ambientes hidrotermal e pegmatítico foram submetidas a ensaios por espectroscopia de absorção na região do infravermelho por transformada de Fourier (FTIR e irradiação gama seguida ou não de tratamento térmico. Os espectros obtidos por FTIR mostram bandas correlacionadas a elementos dopantes, os quais indicam o potencial da amostra pelo aparecimento de cor e permitem determinar as doses que serão aplicadas na irradiação gama e as temperaturas que serão utilizadas no tratamento térmico. Os resultados dos ensaios mostraram que quartzo de ambiente hidrotermal com valores anômalos de ferro, com banda FTIR a 3.585cm-1, fator fa > 3,3 e área entre 400 e 600u.a*cm-1, poderá desenvolver a cor violeta; quartzo com anomalias de lítio na estrutura do cristal derivado de núcleo de pegmatitos altamente diferenciados ricos em minerais de lítio apresentando banda FTIR a 3.485cm-1, fator fLi > 2,0 e irradiado com doses de 65 a 400kGy pode desenvolver cores amarelo-esverdeadas a acastanhadas. É possível concluir que ametista e prasiolita são produzidas de quartzo de ambiente hidrotermal, enquanto variedades gemológicas raras, tais como green gold, beer, cognac, whisky e champagne são produzidas de quartzo de pegmatitos altamente diferenciados, que contêm minerais de lítio.Despite the large production of quartz in Minas Gerais, little is known about the geological environment influence on the generation of colored varieties by treatment.

  4. [The pharmacopoeia of Father Morin in 1864].

    Science.gov (United States)

    Bonnemain, Bruno

    2016-03-01

    The "pharmacopoeia or collection of divine remedies found in the documents of an old rural priest after his death" is a publication of nearly 400 pages including a long list of diseases with their associated treatments, followed by several recipes for the day to day life (such as: how to preserve wine, how to produce Champagne's wine, recipes for filler paste, etc.). A last part, very unique, is dedicated to evil spells, i.e. to diseases that do not have natural explanations and for which Saint Benoit's medal works wonders, according to the author. This pharmacopoeia of 1864 is a typical example of "incoherent collection" mentioned by Tardieu in 1862 concerning clergy and pharmacy. It is, from that point of view, the archetype that pharmacists wanted to see disappearing after the law of germinal year XI (1803), but that persisted until the beginning of the XXth century: the illegal practice of pharmacy by priests and nuns.

    2012-01-01

    The nearby dwarf starburst galaxy NGC 5253 hosts a deeply embedded radio-infrared supernebula excited by thousands of O stars. We have observed this source in the 10.5{\\mu}m line of S+3 at 3.8 kms-1 spectral and 1.4" spatial resolution, using the high resolution spectrometer TEXES on the IRTF. The line profile cannot be fit well by a single Gaussian. The best simple fit describes the gas with two Gaussians, one near the galactic velocity with FWHM 33.6 km s-1 and another of similiar strength and FWHM 94 km s-1 centered \\sim20 km s-1 to the blue. This suggests a model for the supernebula in which gas flows towards us out of the molecular cloud, as in a "blister" or "champagne flow" or in the HII regions modelled by Zhu (2006).

  7. Foaming in stout beers

    2011-10-01

    We review the differences between bubble formation in champagne and other carbonated drinks, and stout beers which contain a mixture of dissolved nitrogen and carbon dioxide. The presence of dissolved nitrogen in stout beers gives them several properties of interest to connoisseurs and physicists. These remarkable properties come at a price: stout beers do not foam spontaneously and special technology, such as the widgets used in cans, is needed to promote foaming. Nevertheless, the same mechanism, nucleation by gas pockets trapped in cellulose fibers, responsible for foaming in carbonated drinks is active in stout beers, but at an impractically slow rate. This gentle rate of bubble nucleation makes stout beers an excellent model system for investigating the nucleation of gas bubbles. The equipment needed is modest, putting such experiments within reach of undergraduate laboratories. We also consider the suggestion that a widget could be constructed by coating the inside of a beer can with cellulose fibers.

  9. Radiocarbon 14C differentiation of sparkling and carbonated wines

    International Nuclear Information System (INIS)

    Specific 14C-activities, percent of modern 14C-activity, and calculated percent of fermentation CO2 are presented for CO2 contained in commercial sparkling wines, labeled as champagne or produced by the bulk (charmat) process. These data are given for the production years 1976-1982. The survey encompassed effervescent wines produced in Spain, Italy, West Germany, California, and New York. Addition of synthetic CO2 to approximately 40 samples represented as sparkling wines was indicated by low 14C-activities of CO2 in these wines. Data for 14C-activity were also presented for the ethanol distilled from sparkling wines for the years 1977-1980. In all cases, the 14C-activity of ethanol was appropriate to the year of vintage

  10. Gravity-capillary free-surface flows

    CERN Document Server

    Vanden-Broeck, Jean-Marc

    2010-01-01

    Free surface problems occur in many aspects of science and of everyday life such as the waves on a beach, bubbles rising in a glass of champagne, melting ice, pouring flows from a container and sails billowing in the wind. Consequently, the effect of surface tension on gravity-capillary flows continues to be a fertile field of research in applied mathematics and engineering. Concentrating on applications arising from fluid dynamics, Vanden-Broeck draws upon his years of experience in the field to address the many challenges involved in attempting to describe such flows mathematically. Whilst careful numerical techniques are implemented to solve the basic equations, an emphasis is placed upon the reader developing a deep understanding of the structure of the resulting solutions. The author also reviews relevant concepts in fluid mechanics to help readers from other scientific fields who are interested in free boundary problems.

    2015-01-01

    The Orion-Eridanus superbubble is the prototypical superbubble due to its proximity and evolutionary state. Here, we provide a synthesis of recent observational data from WISE and Planck with archival data, allowing to draw a new and more complete picture on the history and evolution of the Orion-Eridanus region. We discuss the general morphological structures and observational characteristics of the superbubble, and derive quantitative properties of the gas- and dust inside Barnard's Loop. We reveal that Barnard's Loop is a complete bubble structure which, together with the lambda Ori region and other smaller-scale bubbles, expands within the Orion-Eridanus superbubble. We argue that the Orion-Eridanus superbubble is larger and more complex than previously thought, and that it can be viewed as a series of nested shells, superimposed along the line of sight. During the lifetime of the superbubble, HII region champagne flows and thermal evaporation of embedded clouds continuously mass-load the superbubble inte...

  14. French vineyards provide information that opens ways for effective resistance management of Botrytis cinerea (grey mould).

    Resistance to fungicides is an evolutionary process resulting from the selection of advantageous genotypes in naturally diverse populations. Seven fungicide modes of action are authorised to control grey mould caused by Botrytis cinerea on grapevine in France, and five of them have encountered specific resistance, with variable frequencies in populations and possible consequences for field fungicide efficacy. Moreover, multidrug resistance is caused by fungicide efflux and allows a weak resistance towards six unrelated modes of action. Here, a review is given of the fungicide resistance status of B. cinerea in France, particularly in the vineyards of Champagne, which are the most affected. Recently developed resistance and recent findings concerning the associated resistance mechanisms are focused upon in particular. Finally, antiresistance strategies are presented, and examples of managed resistance are discussed in a more general manner with the aim of extending this knowledge to other crops and countries undergoing similar resistance problems.

    Two long core chapters on oil and on nonfuel minerals, along with an exposition of the econometrics of primary commodities, give the reader a basic insight into the economic techniques and their uses. There are also chapters on coal, gas, and uranium, which include an overview of the Soviet energy sector and the Australian coal industry. The book introduces oil refining, petrochemicals, futures markets, inventories, capital costs, tin, stock-flow models, and other topics not usually handled in most economics text and reference books. There is also a short survey of iron and steel. The book concludes with the note that attempts to check inflation by monetary means in the presence of the kind of consumer and corporate debt that exists today is begging for catastrophe. Monetarism, like champagne, is good for pleasure, but very bad for business. 210 references, 47 figures, 41 tables.

    Either at the champagne glass or at the oceanic scales, the tiny capillary bubbles covering a free surface burst in ejecting myriads of airborne droplets, key mediators in the gaseous exchange between the liquid and its surroundings. Focusing on the bubble bursting jet, prelude for these aerosols, we propose a simple scaling for the jet velocity and we unravel experimentally the intricate roles of bubble shape, capillary waves and viscosity in the jet formation. We demonstrate that capillary waves always evolve into a self-similar focusing wave, but are also responsible for the breakdown of self-similarity. By its smoothing action on these hindering ripples, viscosity is shown to unexpectedly promote thinner and faster jets. These results prompt the question of the possible critical role of liquid temperature in aerosol production.

    Microbial adaptations to environmental extremes, including high temperature and low pH conditions typical of geothermal settings, are of interest in astrobiology and origin of life investigations. The lipid biomarkers preserved in silica deposits associated with six geothermal areas in the Taupo Volcanic Zone were investigated and variations in lipid composition as a function of temperature and pH were assessed. Lipid analyses reveal highly variable abundances and distributions, reflecting community composition as well as adaptations to extremes of pH and temperature. Biomarker profiles reveal three distinct microbial assemblages across the sites: the first in Champagne Pool and Loop Road, the second in Orakei Korako, Opaheke and Ngatamariki, and the third in Rotokawa. Similar lipid distributions are observed in sinters from physicochemically similar springs. Furthermore, correlation between lipid distributions and geothermal conditions is observed. The ratio of archaeol to bacterial diether abundance, bacterial diether average chain length, degree of GDGT cyclisation and C31 and C32 hopanoic acid indices typically increase with temperature. At lower pH, the ratio of archaeol to bacterial diethers, degree of GDGT cyclisation and C31 and C32 hopanoic acid indices are typically higher. No trends in fatty acid distributions with temperature or pH are evident, likely reflecting overprinting due to population influences.

    Energy record Standing before the CERN personnel in the Main Auditorium on 25 November 1959, John Adams held not a bottle of champagne but a bottle of vodka. It had been presented to him a few months earlier during a visit to Dubna in the Soviet Union, where the world's most powerful accelerator had just been commissioned. He had been given strict instructions not to open the bottle until Dubna's energy record of 10 GeV had been broken. On 24 November, the record was smashed by CERN's brand new machine, the Proton Synchrotron, which accelerated protons at 24 GeV, over twice the energy of the Dubna machine. Before sending the empty bottle back to the Soviet Union, John Adams, who had headed the accelerator's construction, placed the recording of the signal in it as proof of the record. More than 40 years later, the PS is still going strong, delivering beams with particle densities a thousand times greater than when it first started operation. Over the years, other accelerators have grown up around it and the...

  7. Fully developed turbulence in slugs of pipe flows

    Despite over a century of research, transition to turbulence in pipe flows remains a mystery. In theory the flow remains laminar for arbitrarily large Reynolds number, Re. In practice, however, the flow transitions to turbulence at a finite Re whose value depends on the disturbance, natural or artificial, in the experimental setup. The flow remains in the transition state for a range of Re ~ 0 (1000) ; for larger Re the flow becomes fully developed. The transition state for Re > 3000 consists of axially segregated regions of laminar and turbulent patches. These turbulent patches, known as slugs, grow as they move downstream. Their lengths span anywhere between a few pipe diameters to the whole length of the pipe. Here we report Stereo Particle Image Velocimetry measurements in the cross-section of the slugs. Notwithstanding the continuous growth of the slugs, we find that the mean velocity and stress profiles in the slugs are indistinguishable from that of statistically-stationary fully-developed turbulent flows. Our results are independent of the length of the slugs. We contrast our results with the well-known work of Wygnanski & Champagne (1973), whose measurements, we argue, are insufficient to draw a clear conclusion regarding fully developed turbulence in slugs.

    On Tuesday, 8 October, CERN welcomed Jean de Toledo, aged 100 years and 1 month (as he is eager to point out). He is the president of the “Pharmacies principales de Genève” and has a passion for physics.   During his meeting with the Director-General, Jean de Toledo was given the LHC: the Large Hardon Collider book, which he made sure to have Rolf sign. He was born in Geneva in 1911, just when Rutherford was discovering the structure of the atom. Jean De Toledo says that it has been a long-standing dream of his to visit the Laboratory, to the construction of which he was a witness. “CERN is a fabulous place, and a great plus for Geneva,” he said in a discussion with CERN Director-General Rolf Heuer. Smiling and with a glass of champagne in his hand, he received a copy of the book LHC: the Large Hadron Collider and a “magic coffee mug”, whose secret was explained to him by the Director-General. “There is a prod...

    The cultural and natural scientific ambivalence of the heart and alcohol has long been the subject of philosophical, artistic, intellectual and emotional discussions, not uncommonly in a romanticizing manner. The indulgence of alcoholic beverages in moderation is contrasted by the inestimable risks and dangers of alcohol abuse with many cardiovascular implications, such as cardiac arrhythmia, cardiomyopathy and arterial hypertension. The inspirational mental effects of alcohol have been emphasized in many citations from Classical Antiquity through the Middle Ages and even in modern times. In addition to wine and beer many alcoholic drinks, such as Champagne, sparkling wines, whisky (or whiskey), brandy (Cognac) and fruit brandies have a nearly ritual culture of traditions and customs, without which social life would be unthinkable. The interplay between enjoyment and displeasure is emphasized in the year 2016 with the 500-year jubilee of the German purity requirements for beer with countless events, including the Bavarian State Exhibition 2016. Recently, evidence of a neuroprotective effect of alcohol was reported with an improvement of intellectual capacity, which could counteract the widely occurring dementia syndrome. Millions of people could profit from this effect. PMID:27491659

    We are presenting here a follow-up study of the molecular gas and dust in the environs of the star forming region NGC 3503. This study aims at dealing with the interaction of NGC 3503 with its parental molecular cloud, and also with the star formation in the region. To analyze the molecular gas we use CO(2-1), 13CO(2-1), C18O(2-1), and HCN(3-2) line data obtained with the APEX telescope. To study the distribution of the dust, we make use of images at 870 microns from the ATLASGAL survey and IRAC-GLIMPSE archival images. We use public 2MASS and WISE data to search for candidate YSOs in the region. The new APEX observations allowed the substructure of the molecular gas in the velocity range from -28 to -23 km/s to be imaged in detail. The morphology of the molecular gas close to the nebula, the location of the PDR, and the shape of radio continuum emission suggest that the ionized gas is expanding against its parental cloud, and confirm the "champagne flow" scenario. We have identified several molecular clumps ...

    2013-05-01

    Full Text Available Sublimation is an idea often used to give a psychoanalytic interpretation of artistic creativity. Focusing on the lyric speaker within the poem and considering the text as a mise-en-scène of poetic creation, the paper intends to investigate why sublimation could not be the right key to understanding the phenomenon. The subject’s dynamics, in modern poetry, show themselves as a continuous failure in the repeated attempt to possess the object. The speaker’s affective and cognitive desire is produced and constantly renewed by the impossibility of possessing the object (above all in its representation. But it is only in such a gap that the subject can exists. In order to feel desire, there should be an illusion of possession and representation. Subject and object create each other in lyric poem, and the former comes to coincide with the desire for the latter, it does not exist outside that desire.  Since lyric poetry shows itself as the unfolding of a subject that voices itself and is always involved in an object relation, it can be a privileged field of investigation for this kind of phenomena. Two poets will be taken into consideration: Thibaut de Champagne, a late trouvère who summons up the Provençal tradition, and Charles Baudelaire, one of the modern poets that have most deeply investigated the reality lack of sense.

    2010-01-01

    We present 52-93 micron spectra, obtained with the Spitzer Space Telescope, of luminous compact far-IR sources in the SMC. These comprise 9 Young Stellar Objects (YSOs), the compact HII region N81 and a similar object within N84, and two red supergiants (RSGs). The spectra of the sources in N81 (of which we also show the ISO-LWS spectrum between 50-170 micron) and N84 both display strong [OI] 63-micron and [OIII] 88-micron fine-structure line emission. We attribute these lines to strong shocks and photo-ionized gas, respectively, in a ``champagne flow'' scenario. The nitrogen content of these two HII regions is very low, definitely N/O<0.04 but possibly as low as N/O<0.01. Overall, the oxygen lines and dust continuum are weaker in star-forming objects in the SMC than in the LMC. We attribute this to the lower metallicity of the SMC compared to that of the LMC. Whilst the dust mass differs in proportion to metallicity, the oxygen mass differs less; both observations can be reconciled with higher densitie...

  16. Ice in the Tropics: the Export of ‘Crystal Blocks of Yankee Coldness’ to India and Brazil

    Directory of Open Access Journals (Sweden)

    Marc W. Herold

    2011-11-01

    Full Text Available The Boston natural ice trade thrived during 1830-70 based upon Frederic Tudor’s idea of combining two useless products – natural winter ice in New England ponds and sawdust from Maine’s lumber mills. Tudor ice was exported extensively to the tropics from the West Indies to Brazil and the East Indies as well as to southern ports of the United States. In tropical ice ports, imported natural ice was a luxury product, e.g., serving to chill claret wines (Calcutta, champagne (Havana and Manaus, and mint juleps (New Orleans and Savannah and used in luxury hotels or at banquets. In the temperate United States, natural ice was employed to preserve foods (cold storage and to cool water (Americans’ peculiar love of ice water. In both temperate and tropical regions natural ice found some use for medicinal purposes (to calm fevers. With the invention of a new technology to manufacture artificial ice as part of the Industrial Revolution, the natural ice export trade dwindled as import substituting industrialization proceeded in the tropics. By the turn of the twentieth century, ice factories had been established in half a dozen Brazilian port cities. All that remained of the once extensive global trade in natural ice was a sailing ship which docked in Rio Janeiro at Christmas time laden with ice and apples from New England.

    1993-09-01

    The value of biotin-avidin (B-A) ELISA for the detection of grapevine fanleaf virus (GFLV) in Xiphinema was estimated with field populations and greenhouse subpopulations. Samples consisted of increasing numbers of adults ranging from 1 to 64 in multiples of two. Tests with virus-free X. index populations reared on grapevine and fig plants as negative controls did not reveal a noticeable effect of the host plant. ELISA absorbances of virus-free X. index samples were greater than corresponding absorbances of X. pachtaicum samples. Differences occurred between two X. index field populations from GFLV-infected grapevines in Champagne and Languedoc. In most tests, 1-, 2-, 4-, and 8-nematode samples of virus-free and virus-infected populations, respectively, could not be separated. Consequently, B-A ELISA was not a reliable method for GFLV detection in samples of less than 10 X. index adults, but comparison of the absorbances obtained with increasing numbers may allow differentiation of the viral infectious potential of several populations.

    The study of the interactions among metals, minerals, and humic substances is essential in understanding the migration of inorganic pollutants in the geosphere. A considerable amount of organic matter in the environment is associated with clay minerals. To understand the role of organic matter in the environment and its association with clay minerals, a hybrid clay-based material (HCM), montmorillonite (STx-1)-melanoidin, was prepared from L-tyrosine and L-glutamic acid by the Maillard reaction. The HCM was characterized by elemental analysis, nuclear magnetic resonance, x-ray photoelectron spectroscopy (XPS), scanning transmission x-ray microscopy (STXM), and thermal analysis. The presence of organic materials on the surface was confirmed by XPS and STXM. The STXM results showed the presence of organic spots on the surface of the STx-1 and the characterization of the functional groups present in those spots. Thermal analysis confirmed the existence of organic materials in the montmorillonite interlayer, indicating the formation of a composite of melanoidin and montmorillonite. The melanoidin appeared to be located partially between the layers of montmorillonite and partially at the surface, forming a structure that resembles the way a cork sits on the top of a champagne bottle.

    2016-08-01

    The preparation of yeast starter culture (Pied de Cuve) for producing sparkling wine with the traditional method is a key factor for manufacturing a good Prise de mousse. In this paper, the evolution of total yeast population, its viability during Pied de Cuve preparation, and the pressure profile during the 2nd fermentation in 2 different base wines made from Bombino bianco and Chardonnay grapes were investigated using 4 different commercial active dried yeasts. The study proves that despite the initial differences observed throughout the acclimatization phase, all the tested strains showed similar results on either the total population (from 8.2 × 10(7) cells/mL to 1.3 × 10(8) cells/mL) or cellular viability (from 70% to 84%). Independently from the base wine tested, the kinetic of sugar consumption was faster during the gradual acclimatization to the alcoholic medium (phase II) and slower during the preparation of starter culture in active growth phase (phase III). During both of these phases Saccharomyces cerevisiae bayanus Vitilevure DV10(®) (Station œnotechnique de Champagne) proved to have a higher sugar consumption rate than the other strains. During the Prise de mousse, S. cerevisiae bayanus Lalvin EC-1118(®) (Lallemand) reached the maximum pressure increase within time in both base wines.

  2. The highly ionized, high velocity gas in NGC 6231

    CERN Document Server

    Massa, Derck

    2016-01-01

    It is well known that clusters of massive stars are influenced by the presence of strong winds, that they are sources of diffuse X-rays from shocked gas, and that this gas can be vented into the surrounding region or the halo through the champagne effect. However, the details of how these different environments interact and evolve are far from complete. This paper attributes the broad C IV 1500 absorption features (extending to -1900 \\kms) that are seen in the spectra of main sequence B stars in NGC 6231 to gas in the cluster environment and not the B stars themselves. It is shown that the presence of a WC star, WR 79, in the cluster makes this gas detectable because its wind enriches the cluster gas with carbon. Given the available data, it is not clear whether the absorbing gas is simply the far wind of WR 79 or a collective cluster wind enriched by carbon from the wind of WR 79. If it is simply due to the wind, then this wind must flow, unimpeded for more than 2 pc, suggesting that the inner region of the ...

    Results. Ninety-five percent of a total group of 172 OP of Champagne county filled the postal questionnaire. More than 80% of OP's replies identified illegal PSW. The average prevalence of PSW exposure was 0.7% of the total working population. Environmental tobacco smoke (ETS levels were considered between low and medium for most passive smokers (71%. Main features exposure to ETS at work for non-smokers was associated with female gender (69.5%, age between 40 and 49 years (41.2% and belonging to tertiary sector (75.6%. Environmental tobacco smoke exposures at work was firstly in the office for 49.7% of the subjects and secondly in the restroom for 18% of them. Main medical symptoms encountered by non-smokers were respiratory tractus irritation (81.7%. Eighty-three percent of OPs indicated solution to eradicate PSW. Illegal PSW is really weaker than fifteen years ago. However, the findings support a real ban on smoking in the workplace in order to protect all workers.

    2007-01-01

    Recent studies of methanol and ground-state OH masers at very high spectral resolution have shed new light on small-scale maser processes. The nearby source W3(OH), which contains numerous bright masers in several different transitions, provides an excellent laboratory for high spectral resolution techniques. We present a model of W3(OH) based on EVN observations of the rotationally-excited 6030 and 6035 MHz OH masers taken at 0.024 km/s spectral resolution. The 6.0 GHz masers are becoming brighter with time and show evidence for tangential proper motions. We confirm the existence of a region of magnetic field oriented toward the observer to the southeast and find another such region to the northeast in W3(OH), near the champagne flow. The 6.0 GHz masers trace the inner edge of a counterclockwise rotating torus feature. Masers at 6030 MHz are usually a factor of a few weaker than at 6035 MHz but trace the same material. Velocity gradients of nearby Zeeman components are much more closely correlated than in th...

    Geneva, 30 November 2009. CERN1’s Large Hadron Collider has today become the world’s highest energy particle accelerator, having accelerated its twin beams of protons to an energy of 1.18 TeV in the early hours of the morning. This exceeds the previous world record of 0.98 TeV, which had been held by the US Fermi National Accelerator Laboratory’s Tevatron collider since 2001. It marks another important milestone on the road to first physics at the LHC in 2010. “We are still coming to terms with just how smoothly the LHC commissioning is going,” said CERN Director General Rolf Heuer. “It is fantastic. However, we are continuing to take it step by step, and there is still a lot to do before we start physics in 2010.

    2003-07-01

    New technologies for reducing the sludge production of municipal or industrial WWTP have been appeared during the last few years. One of these innovative processes, Bio THELYS, consists in enhancing the biodegradability of sludge by a stage of thermal hydrolysis. The hydrolysed sludge could then be sent upstream to a biological step either aerobic or anaerobic. The objective is to increase the global mineralisation of the pollution entering the WWTP in order to decrease the waste leaving it, i.e. mainly the sludge. A 2500 population equivalent prototype was installed on a WWTP, in Champagne - France. Thermal hydrolysis is carried out under a temperature of 150-185{sup o}C, a pressure of 10-15 bar with an hydraulic retention time of 30-60 minutes. Thermal hydrolysis is implemented on a secondary recycling loop on the biological basin. Trials started in 1999 and are still on operation. A close monitoring of the WWTP was set up focusing especially on sludge characteristics, treated water quality, yield of sludge production reduction and plant operation. Bio THELYS could achieve a reduction in sludge production up to 70% on the plant. (author)

  9. World-Wide Experience with SRF Facilities

    International Nuclear Information System (INIS)

    The speaker will review and analyze the performance of existing SRF facilities in the world, addressing issues of usage and availability for different customers (HEP research, material sciences, ADS). Lessons learned should be summarized for proposed future facilities (ILC, Project X, Muon Collider). The first use of superconducting cavities for accelerating beams was at HEPL, Stanford University in the early sixties. Rather quickly, other laboratories followed suit, notably the University of Illinois at Champagne, Urbana and Cornell University. There were two main uses, which still persist today. The first is to provide accelerated particles as an injector or for fixed target experiments. The second is to maintain circulating beams, either for synchrotron light sources or for colliding beam experiments. Given the differing requirements, these two uses led to rather different implementations and, in particular, different average operating gradients. A second difference in the implementation is the speed of the particle being accelerated. Electrons are sufficiently relativistic at low beam energies (> ∼ 5 MeV) that cavities designed for relativistic beams can also function acceptably at low energy. This is not the case for protons or ion accelerators so, until recently, copper cavities were used to cover the first ∼ 100 MeV. Superconducting cavities are now also being proposed to cover this energy range as well using a series of superconducting cavities, each of which is matched to the particle velocity.

  10. Non-Destructive Optical Monitoring of Grape Maturation by Proximal Sensing

    Full Text Available A new, commercial, fluorescence-based optical sensor for plant constituent assessment was recently introduced. This sensor, called the Multiplex® (FORCE-A, Orsay, France, was used to monitor grape maturation by specifically monitoring anthocyanin accumulation. We derived the empirical anthocyanin content calibration curves for Champagne red grape cultivars, and we also propose a general model for the influence of the proportion of red berries, skin anthocyanin content and berry size on Multiplex® indices. The Multiplex® was used on both berry samples in the laboratory and on intact clusters in the vineyard. We found that the inverted and log-transformed far-red fluorescence signal called the FERARI index, although sensitive to sample size and distance, is potentially the most widely applicable. The more robust indices, based on chlorophyll fluorescence excitation ratios, showed three ranges of dependence on anthocyanin content. We found that up to 0.16 mg cm−2, equivalent to approximately 0.6 mg g−1, all indices increase with accumulation of skin anthocyanin content. Excitation ratio-based indices decrease with anthocyanin accumulation beyond 0.27 mg cm−2. We showed that the Multiplex® can be advantageously used in vineyards on intact clusters for the non-destructive assessment of anthocyanin content of vine blocks and can now be tested on other fruits and vegetables based on the same model.

  11. [Alcohol and the heart : Anecdotes on the history of a checkered relationship].

    2016-09-01

    The cultural and natural scientific ambivalence of the heart and alcohol has long been the subject of philosophical, artistic, intellectual and emotional discussions, not uncommonly in a romanticizing manner. The indulgence of alcoholic beverages in moderation is contrasted by the inestimable risks and dangers of alcohol abuse with many cardiovascular implications, such as cardiac arrhythmia, cardiomyopathy and arterial hypertension. The inspirational mental effects of alcohol have been emphasized in many citations from Classical Antiquity through the Middle Ages and even in modern times. In addition to wine and beer many alcoholic drinks, such as Champagne, sparkling wines, whisky (or whiskey), brandy (Cognac) and fruit brandies have a nearly ritual culture of traditions and customs, without which social life would be unthinkable. The interplay between enjoyment and displeasure is emphasized in the year 2016 with the 500-year jubilee of the German purity requirements for beer with countless events, including the Bavarian State Exhibition 2016. Recently, evidence of a neuroprotective effect of alcohol was reported with an improvement of intellectual capacity, which could counteract the widely occurring dementia syndrome. Millions of people could profit from this effect.

    Full Text Available Background. The S-ROM-A prosthesis has been designed for the Asian proximal femur with a small deformed shape and narrow canal. In this study, the clinical and radiological results using the S-ROM-A prosthesis for Japanese patients with severe deformity due to dysplasia and excessive posterior pelvic tilt were examined. Methods. 94 hips were followed up for a mean of 55 months, with a mean age at surgery of 61 years. The primary diagnoses were 94 coxarthritis cases, including 51 dysplasia and 37 primary OA, 1 avascular necrosis, 2 traumatic arthritis, and 3 Perthes disease. Thirty-one hips had been treated with osteotomy of the hip joints. Preoperative intramedullary canal shapes were stovepipe in 23 hips, normal in 51 hips, and champagne-flute in 5 hips. The maximum pelvic inclination angle was 56°. Results. The mean JOA score improved from 46 points preoperatively to 80 points at final follow-up. On radiological evaluation of the fixation of the implants according to the Engh classification, 92 (97% hips were classified as “bone ingrown fixation.” Conclusion. In primary THA, using the S-ROM-A prosthesis for Asian patients with proximal femoral deformity, even after osteotomy and with posterior pelvic tilt, provided good short- to midterm results.

    H2O, CH4 and CO2 are major greenhouse gases with a strong impact on climate. The concentrations of CO2 and CH4 have dramatically increased since the beginning of the industrialization era due to anthropogenic activities, contributing thereby to the global warming. Anthropogenic activities as fossil fuels, ruminant, and biomass burning constitute the major sources of carbon dioxide and methane. The increase of H2O concentration in the stratosphere could cause a cooling of this atmospheric region, impacting the recovery of the ozone layer. Therefore, having information and data about the vertical distribution of H2O, CO2 and CH4 is very useful to improve our knowledge of the future of our climate. We have developed, with the help of French space agency (CNES) and CNRS, two laser diode sensors PicoSDLA and AMULSE devoted to the in situ measurements of H2O, CH4 and CO2 from balloon platforms. These instruments were operated from open stratospheric balloons in Timmins, CA, in August 2014 and 2015. We report and discuss the instrumental achievements of both sensors during these flights in the UT-LS. Aknowledgments: The authors acknowledge financial supports from CNES, CNRS and the region Champagne-Ardenne.

  15. Data-driven optimization of dynamic reconfigurable systems of systems.

    Energy Technology Data Exchange (ETDEWEB)

    Tucker, Conrad S.; Eddy, John P.

    2010-11-01

    This report documents the results of a Strategic Partnership (aka University Collaboration) LDRD program between Sandia National Laboratories and the University of Illinois at Urbana-Champagne. The project is titled 'Data-Driven Optimization of Dynamic Reconfigurable Systems of Systems' and was conducted during FY 2009 and FY 2010. The purpose of this study was to determine and implement ways to incorporate real-time data mining and information discovery into existing Systems of Systems (SoS) modeling capabilities. Current SoS modeling is typically conducted in an iterative manner in which replications are carried out in order to quantify variation in the simulation results. The expense of many replications for large simulations, especially when considering the need for optimization, sensitivity analysis, and uncertainty quantification, can be prohibitive. In addition, extracting useful information from the resulting large datasets is a challenging task. This work demonstrates methods of identifying trends and other forms of information in datasets that can be used on a wide range of applications such as quantifying the strength of various inputs on outputs, identifying the sources of variation in the simulation, and potentially steering an optimization process for improved efficiency.

    On 3 August 2012, the Linac4 radiofrequency quadrupole (RFQ) module was installed at the accelerator test-stand in Building 152. The site will be the module’s home for almost a year, as the linear accelerator enters the assembly and testing stage.   Final module assembly is carried out before installation in Building 152.  Over the next Long Shutdown (LS2), Linac4 will replace the current Linac2 linear accelerator as the first link in CERN’s accelerator chain. It will deliver particles at 160 MeV to the PS Booster, more than triple the energy currently delivered by Linac2. But before the accelerator team can pop the champagne, the various elements of Linac4 will be tested and re-tested in facilities across CERN. “The first Linac4 tests are currently underway, starting with the CERN-built RFQ,” says Carlo Rossi, a physicist in the RF Group of the Beams (BE) Department and the RFQ project coordinator. “It’s an extremely impre...

    CERN Multimedia

    2009-01-01

    It’s been 20 years since the first electron positron collision at LEP, and I have to confess to a little self-indulgence in my message this week. Back then I was a member of the OPAL collaboration, the first to see collisions at LEP just before midnight on 13 August 1989 and almost exactly one month after the first circulating beam. It was a historic moment, and the atmosphere in the OPAL control room, 100 metres underground, was one of anticipation and excitement. We reported back to the LEP control room, champagne duly arrived, and over the next few hours, all the experiments were recording data. The pilot run was as smooth as it could be, and within weeks we were announcing new physics. It’s interesting to contrast the start-up of LEP with that of the LHC. With the benefit of hindsight, LEP seems to have got going without a hitch, and indeed it was a smooth start. We circulated beam on 14 July, much to the joy of one of our host states, and it was just a month ...

    2012-03-01

    Full Text Available The objective of this paper is to provide a preliminary discussion of how to improve our conceptualization of social thresholds using (1 a more sociological analysis of social resilience, and (2 results from research carried out in collaboration with the Champagne and Aishihik First Nations of the Yukon Territory, Canada. Our sociological analysis of the concept of resilience begins with a review of the literature followed by placement of the concept in the domain of sociological theory to gain insight into its strengths and limitations. A new notion of social thresholds is proposed and case study research discussed to support the proposition. Our findings suggest that rather than view social thresholds as breakpoints between two regimes, as thresholds are typically conceived in the resilience literature, that they be viewed in terms of collectively recognized points that signify new experiences. Some examples of thresholds identified in our case study include power in decision making, level of healing from historical events, and a preference for small-scale development over large capital intensive projects.

    2012-03-01

    Full Text Available We describe the protocols of two mark-resight abundance surveys, using temporary dye-marks, for the Aishihik woodland caribou (Rangifer tarandus caribou and wood bison (Bison bison athabascae populations (herds in the southwest Yukon Territory, Canada. We also provide recommendations based on experiences from these surveys for biologists and managers considering this approach. The Aishihik woodland caribou herd was the focus of intensive management in the 1990s aimed at recovering the herd. Following recovery activities, a target size of 2000 animals was determined and the Champagne-Aishihik Traditional Territory Community-Based Wildlife Management Plan recommended an estimate of the herd’s size be completed before the year 2013. We used an aerial mark-resight approach to estimate the herd’s size in March 2009. Caribou (n = 59 were marked from a helicopter with temporary dye, delivered via a CO2-powered rifle. Two independent resighting sessions were subsequently carried out via helicopter. The herd was estimated at 2044 animals (90% CI: 1768 – 2420 with an overall resighting rate of 0.47. The mean annual growth rate (λ of the herd from 1997 – 2009 was 1.05 (SE = 0.01. The Aishihik wood bison herd was estimated at 1151 (90% CI: 998 – 1355. Our study suggests that ungulates temporarily marked with dye can be successfully used to obtain statistically sound population estimates.

    Full Text Available Les produits pétroliers et le charbon continueront à couvrir les besoins énergétiques pendant plusieurs décennies. La pollution par le SOZ, provenant de la combustion de ces combustibles fossiles, devient une préoccupation pour la population et les Pouvoirs publics. La désulfuration des fumées de combustion devrait, à plus ou moins longue échéance, se développer. L'Institut Français du Pétrole (IFP, mettant à profit ses travaux dans le domaine de la désulfuration, a développé un procédé de traitement des fumées. L'IFP, en collaboration avec Électricité de France (EDF, a effectué en 1976 une opération de démonstration à une échelle pilote (30 MW dans la Centrale de Champagne-sur-Oise. Le procédé consiste à éliminer le S02 des fumées par lavage avec une solution ammoniacale, à produire du soufre à partir de la liqueur obtenue et à recycler l'ammoniaque dans l'étape de lavage. Après quelques modifications d'ordre technologique, l'unité de démonstration a fonctionné d'une manière continue pendant une période de trois mois, correspondant à l'objectif fixé. Les résultats obtenus permettent, actuellement, d'envisager une application de cette technique à une échelle de 250 MW. Oil and coal productswill continue to fulfill energy needs for several more decades. Pollution by SO2 coming from the combustion of such fossil fuels is becoming a preoccupation for the population and the public authorities. The desulfurization of combustion fumes should continue ta develop in the more or less long run. Institut Français du Pétrole (IFP has taken advantage of its research in the fixed of desulfurization to develop a stock-gas treating process. In collaboration with Électricite de Fronce (EDF, IFP carried out a demonsiration operation in 1976 on a pilot-plant scale (30MW in a power plant at Champagne-sur-Oise. The process consists in removing S02 from stock gases by scrubbing them with an ammonia solution

    Light-toned soils were exposed, through serendipitous excavations by Spirit Rover wheels, at eight locations in the Columbia Hills. Their occurrences were grouped into four types on the basis of geomorphic settings. At three major exposures, the light-toned soils are hydrous and sulfate-rich. The spatial distributions of distinct types of salty soils vary substantially: with centimeter-scaled heterogeneities at Paso Robles, Dead Sea, Shredded, and Champagne-Penny, a well-mixed nature for light-toned soils occurring near and at the summit of Husband Hill, and relatively homogeneous distributions in the two layers at the Tyrone site. Aeolian, fumarolic, and hydrothermal fluid processes are suggested to be responsible for the deposition, transportation, and accumulation of these light-toned soils. In addition, a change in Pancam spectra of Tyrone yellowish soils was observed after being exposed to current Martian surface conditions for 175 sols. This change is interpreted to be caused by the dehydration of ferric sulfates on the basis of laboratory simulations and suggests a relative humidity gradient beneath the surface. Si-rich nodules and soils were observed near the major exposures of S-rich soils. They possess a characteristic feature in Pancam visible near-infrared (Vis-NIR) spectra that may be diagnostic of hydrated species, and this spectral feature can be used to search for additional Si-rich species. The exposures of hydrated salty soils within various geomorphic settings imply the potential existence of hydrous minerals in similar settings over a much wider area. Hydrous sulfates represent one of the candidates that may contribute the high level of water equivalent hydrogen in equatorial regions detected by the Neutron Spectrometer on Mars Odyssey.

Las cifras de importación para los distintos tipos y envases de vinos reflejan estos cambios. La internación de tintos a granel experimenta una caída sistemática desde la década del 1870, no así el champaña que aún no se fabricaba en Chile. Más significativa es la creciente figuración de los vinos nacionales en los menús de los banquetes oficiales y sociales en el períodoThe production, imports and consumption of wine underwent significant changes in the years between Independence and the eve of the First World War. This article studies the introduction into Chile of new varieties of vines, and changes in winemaking techniques from the middle of the 19th century onwards. Annual production figures from the different provinces show the gradual penetration of the new varieties, and contemporary sources attest to the differences in the quality of the wines. Import figures for the different types of wine reflect these changes. Imports of plain red wines, though not for champagnes, show a steady decline from the 1870s. More tellingly, Chilean wines were increasingly served in official and social banquets during this period as indicated in the corresponding menus

  11. The characterization of Helicobacter pylori DNA associated with ancient human remains recovered from a Canadian glacier.

    Full Text Available Helicobacter pylori is a gram-negative bacterium that colonizes the stomach of nearly half of the world's population. Genotypic characterization of H. pylori strains involves the analysis of virulence-associated genes, such as vacA, which has multiple alleles. Previous phylogenetic analyses have revealed a connection between modern H. pylori strains and the movement of ancient human populations. In this study, H. pylori DNA was amplified from the stomach tissue of the Kwäday Dän Ts'ìnchi individual. This ancient individual was recovered from the Samuel Glacier in Tatshenshini-Alsek Park, British Columbia, Canada on the traditional territory of the Champagne and Aishihik First Nations and radiocarbon dated to a timeframe of approximately AD 1670 to 1850. This is the first ancient H. pylori strain to be characterized with vacA sequence data. The Tatshenshini H. pylori strain has a potential hybrid vacA m2a/m1d middle (m region allele and a vacA s2 signal (s region allele. A vacA s2 allele is more commonly identified with Western strains, and this suggests that European strains were present in northwestern Canada during the ancient individual's time. Phylogenetic analysis indicated that the vacA m1d region of the ancient strain clusters with previously published novel Native American strains that are closely related to Asian strains. This indicates a past connection between the Kwäday Dän Ts'ìnchi individual and the ancestors who arrived in the New World thousands of years ago.

    Introduction. Exposure to passive smoking at work has been forbidden for few years in France. This study's aim is to estimate the prevalence of passive smoking at work (PSW), the characteristics of illegal passive smoking and to identify eventual respiratory effects. Methods. Occupational practitioners (OPs) of a French county of 320,000 wage earners were contacted by mail. Then OP answered questions from a standardized questionnaire. These questions concerned the practised job, exposure features linked to PSW and health effects in relationship with second-hand smoke in workplace, and the focus on nonsmoker encountered by OP during the most recent occupational medical examination. Results. Ninety-five percent of a total group of 172 OP of Champagne county filled the postal questionnaire. More than 80% of OP's replies identified illegal PSW. The average prevalence of PSW exposure was 0.7% of the total working population. Environmental tobacco smoke (ETS) levels were considered between low and medium for most passive smokers (71%). Main features exposure to ETS at work for non-smokers was associated with female gender (69.5%), age between 40 and 49 years (41.2%) and belonging to tertiary sector (75.6%). Environmental tobacco smoke exposures at work was firstly in the office for 49.7% of the subjects and secondly in the restroom for 18% of them. Main medical symptoms encountered by non-smokers were respiratory tractus irritation (81.7%). Eighty-three percent of OPs indicated solution to eradicate PSW. Illegal PSW is really weaker than fifteen years ago. However, the findings support a real ban on smoking in the workplace in order to protect all workers. PMID:21991448

    Small portable rainfall simulators are considered as a useful tool to analyze soil erosion processes in cultivated lands. European research groups of Spain (Valencia, Málaga, Lleida, Madrid and La Rioja), France (Reims) or Germany (Trier) have used different rainfall simulators (varying in drop size distribution and fall velocities, kinetic energy, plot forms and sizes, and field of application)to study soil loss, surface flow, runoff and infiltration coefficients in different experimental plots (Valencia, Montes de Málaga, Penedès, Campo Real and La Rioja in Spain, Champagne in France and Mosel-Ruwer valley in Germany). The measurements and experiments developed by these research teams give an overview of the variety in the methodologies with rainfall simulations in studying the problem of soil erosion and describing the erosion features in different climatic environments, management practices and soil types. The aim of this study is: i) to investigate where, how and why researchers from different wine-growing regions applied rainfall simulations with successful results as a tool to measure soil erosion processes; ii) to make a qualitative comparison about the general soil erosion processes in European terroirs; iii) to demonstrate the importance of the development a standard method for soil erosion processes in vineyards, using rainfall simulators; iv) and to analyze the key factors that should be taken into account to carry out rainfall simulations. The rainfall simulations in all cases allowed knowing the infiltration capacity and the susceptibility of the soil to be detached and to generate sediment loads to runoff. Despite using small plots, the experiments were useful to analyze the influence of soil cover to reduce soil erosion and to make comparison between different locations or the influence of different soil characteristics.

    A statistical analysis was conducted on long-term climate records for sites bordering Okanagan Lake in the Okanagan Valley viticultural region of British Columbia, Canada. Average wine grape growing season temperatures are increasing rapidly in the area over the post-1980 period at rates upwards of 7.0±1.3°C/century. Similar increases in the average dormant season temperature are evident. These temperature changes are likely some of the most extreme observed among the world's wine producing areas during the past few decades. Growing degree day base 10°C (GDD10) has increased by nearly 50% at some locations since the 1970s, resulting in major impacts on the corresponding climate classification for viticulture. If current climate trends continue, the southern and central portions of the region will likely enter Winkler region II within the next few decades, placing them in the same category as well-established warmer wine regions from France, Spain, Italy, and Australia. The large dormant season temperature increases over the last several decades have resulted in the area no longer being a cold season outlier when compared to most other cool-climate viticultural areas. Based on average growing season temperatures, the southern end of Okanagan Lake has moved out of the cool-climate viticultural classification and into the intermediate zone, while the central and northern regions are now at the cool/intermediate viticulture interface, similar to the historical positions of the Rhine Valley in Germany, northern Oregon in the United States, and the Loire Valley, Burgundy-Cote, Burgundy-Beaujolais, and Champagne appelations of France. The corresponding suitable grape species for the area have evolved into warmer region varietals during this time frame, having substantial economic impacts on producers. Increased temperatures are also expected to bring greater threats from agricultural pests, notably Pierce's disease from the bacterium Xylella fastidiosa. PMID:26971218

    While much is known about alcohol use in adolescence and beyond, factors leading to such behaviors are rooted much earlier in life. To investigate what preschoolers (aged three to six) know about alcohol and adult alcohol use, we developed an electronic version (eABT) of the Appropriate Beverage Task (Zucker, Kincaid, Fitzgerald, & Bingham, 1995). Drawings of adults and children in 11 everyday scenarios and 12 photos of different beverages were shown on a touchscreen computer to 301 three- to six-year-olds (49.5% girls) from 37 preschools and seven nurseries in French-speaking Switzerland. First, the children assigned a beverage to each individual in each drawing, and then were asked if the beverage contained alcohol and if they knew its name. The results revealed that 68.1% correctly classified beer, white wine, red wine and champagne as alcoholic beverages, while 46.4% knew the beverages by name, compared to 83.2% and 73.1% for non-alcoholic beverages. Alcoholic beverages were assigned more often to men (42.2%) than to women (28.7%) or to children (12.7%), and more often to adults at a party (39.4%) than to those playing outdoors (34.7%). In conclusion, children as young as three often have some beverage-specific knowledge. From the age of four onwards, they begin to know that alcoholic beverages contain alcohol. Children aged six and over tend to have some knowledge of adult drinking norms, i.e. who is drinking and in what circumstances. PMID:27240210

  16. The geometry of the bone structure associated with total hip arthroplasty.

    Full Text Available Close adaptation of the prosthesis to the bone is the key to achieving optimal stability and fixation for total hip arthroplasty (THA. However, there have been no adequate studies of bone morphology, especially in different races. The aim of this study was to analyze the geometry of the acetabulum and proximal femur of people from South China, based on three-dimensional reconstruction, and to detect differences between different population subsets. CT scans were performed on 80 healthy volunteers (160 hips from South China, comprising 40 males (80 hips and 40 females (80 hips. The images were imported into Mimics 10.01 to perform 3D reconstruction. THA-associated anatomical parameters were measured and compared with other published data. In comparison with published data, it seemed that people from South China have smaller acetabular abduction angle, larger acetabular supro-inferior diameter, larger neck-shaft angle, smaller offset, thinner femoral shaft and more proximal isthmus, which needed to be further confirmed. There were significant differences between the genders in most parameters. As significant differences in canal flare index (CFI and distal canal flare index (DCFI were found between genders, it was concluded the most significant differences lay in the isthmus of the femur. Among the femora, according to Noble's classification we identified more normal types and fewer stovepipe and champagne-flute types than expected from the literature, indicating that uncemented prostheses would be suitable for most people from South China. Our findings reveal that simply choosing the smallest of a series of prostheses would not necessarily provide a good fit, due to the different trends from the proximal to the distal part of the femur. Significant variation exists in THA-associated anatomy between genders and population subsets. It is therefore imperative that each patient receives individual consideration rather than assuming all patients have

    In order to study the nature, origin, and impact of turbulent velocity fluctuations in the ionized gas of the Orion Nebula, we apply a variety of statistical techniques to observed velocity cubes. The cubes are derived from high resolving power (R ≈ 40 000) longslit spectroscopy of optical emission lines that span a range of ionizations. From Velocity Channel Analysis (VCA), we find that the slope of the velocity power spectrum is consistent with predictions of Kolmogorov theory between scales of 8 and 22 arcsec (0.02 to 0.05 pc). The outer scale, which is the dominant scale of density fluctuations in the nebula, approximately coincides with the autocorrelation length of the velocity fluctuations that we determine from the second order velocity structure function. We propose that this is the principal driving scale of the turbulence, which originates in the autocorrelation length of dense cores in the Orion molecular filament. By combining analysis of the non-thermal line widths with the systematic trends of velocity centroid versus ionization, we find that the global champagne flow and smaller scale turbulence each contribute in equal measure to the total velocity dispersion, with respective root-mean-square widths of 4-5 km s-1. The turbulence is subsonic and can account for only one half of the derived variance in ionized density, with the remaining variance provided by density gradients in photoevaporation flows from globules and filaments. Intercomparison with results from simulations implies that the ionized gas is confined to a thick shell and does not fill the interior of the nebula.

    In 2012, French potato production is down by 10%from 2011 because of a stable acreage combined with a lower yield. The latter is due to poor weather conditions throughout the growing season, especially a very wet early summer which boosted mildew disease. Quality is reported to be below average with more smal sized potatoes. French production of potato is concentrated in the northern (Nord-Pas-de-Calais, Picardie, Champagne-Ardenne, Centre and Haute-Normandie). This paper reviewed the development of French potato industry, including the potato harvest area and production, and the potato processing, fresh potato consumption and foreign trade were also discussed.%  2012年,法国马铃薯产量相对2011年减产10%,虽然种植面积相当,但单产下降了。产量下降的原因主要是由于马铃薯生长季节的不良气候,特别是初夏潮湿的天气导致霉病比较严重。2012年法国马铃薯品质低于前几年的平均水平,小马铃薯居多。法国马铃薯主产区集中在北部(北部-加莱海峡、皮卡第、香槟-阿登、中央和上诺曼底)。本文对法国马铃薯产业进行了分析,包括马铃薯种植面积、产量,并且对马铃薯加工业、家庭消费新鲜马铃薯的情况及法国马铃薯对外贸易进行了讨论。

    Aims: We present here a follow-up study of the molecular gas and dust in the environs of the star forming region NGC 3503. This study aims at dealing with the interaction of the Hii region NGC 3503 with its parental molecular cloud, and also with the star formation in the region, that was possibly triggered by the expansion of the ionization front against the parental cloud. Methods: To analyze the molecular gas we use CO(J = 2 → 1), 13CO(J = 2 → 1), C18O(J = 2 → 1), and HCN(J = 3 → 2) line data obtained with the on-the-fly technique from the APEX telescope. To study the distribution of the dust, we make use of unpublished images at 870 μm from the ATLASGAL survey and IRAC-GLIMPSE archival images. We use public 2MASS and WISE data to search for infrared candidate young stellar objects (YSOs) in the region. Results: The new APEX observations allowed the substructure of the molecular gas in the velocity range from ~-28 km s-1 to -23 km s-1 to be imaged in detail. The morphology of the molecular gas close to the nebula, the location of the PDR, and the shape of radio continuum emission suggest that the ionized gas is expanding against its parental cloud, and confirm the champagne flow scenario. We have identified several molecular clumps and determined some of their physical and dynamical properties such as density, excitation temperature, mass, and line width. Clumps adjacent to the ionization front are expected to be affected by the Hii region, unlike those that are distant from it. We have compared the physical properties of the two kinds of clumps to investigate how the molecular gas has been affected by the Hii region. Clumps adjacent to the ionization fronts of NGC 3503 and/or the bright rimmed cloud SFO 62 have been heated and compressed by the ionized gas, but their line width is not different from those that are too distant from the ionization fronts. We identified several candidate YSOs in the region. Their spatial distribution suggests that stellar

    Observational studies show that there are some gas clouds which are commonly denser than interstellar medium. They are called as“molecular clouds”. Massive stars are formed in these dense molecular clouds, because compact and ultracompact H II regions can form. Theoretically, a Str¨omgren sphere will form if a new massive star with ionizing radiation is born in a uniform medium. However, observations at radio frequencies and infrared radiation show that there are few spherical H II regions. The surveys for compact and ultracompact H II regions in molecular clouds show that part of these embedded H II regions have a cometary morphology. Other observations demonstrate that shells around H II regions are related to star formation, and different morphologies might make a different influence on the evolution results. As quite a lot of non-spherically cometary-shaped compact H II regions were observed in recent years, some researchers have established a number of hydrodynamic models in order to explain the causes of these phenomena. These efforts are helpful in understanding the evolution of compact H II regions and the formation of massive stars. In this article we present the numerical models and calculation methods of cometary-shaped compact H II regions, the contrast between champagne models and bow shock models, and the future development of the field.%研究表明,在新形成大质量恒星辐射的影响下,分子云中会形成高密度的H II 区。近年来观测到一些非球对称彗星状致密H II 区,学者们为了解释这类目标的产生,先后建立了一系列H II 区动力学模型。这些工作有利于进一步认识致密H II 区的形成和演化及大质量恒星的形成。这里介绍了彗星状致密H II 区的模型模拟和计算方法方面的研究进展,阐述了香槟流和弓形激波两种解释模型的异同,以及该领域未来的发展方向。

  2. Etude Climat no. 36 'Regional Climate - Air - Energy Plans: a tool for guiding the energy and climate transition in French regions'

    International Nuclear Information System (INIS)

    Among the publications of CDC Climat Research, 'Climate Reports' offer in-depth analyses on a given subject. This issue addresses the following points: The Regional Climate-Air-Energy Plan (SRCAE - Schema Regional Climat-Air-Energie) was introduced by the Grenelle II legislation. The Plans are co-authored by the State through its decentralised services and the 'Conseil Regionaux' (regional councils) with the objective to guide climate and energy policy in the 26 French regions through to 2020 and 2050. Starting from an assessment of regional greenhouse gas (GHG) emissions, the SRCAE establishes energy transition scenarios based on the sectoral and structural guidelines that constitute the principal framework of the regional strategy. This report offers a detailed analysis of the strategies chosen by the various Regions for a successful transition to low-carbon energy sources, via the study of eleven SRCAEs that were opened to public consultation before the end of July 2012 (Alsace, Aquitaine, Auvergne, Bourgogne, Centre, Champagne-Ardenne, Ile-de-France, Midi-Pyrenees, Nord-Pas de Calais, Picardie and Rhone-Alpes regions). The wide range of methodologies used by the Regions, both to draw up their inventories of GHG emissions and for their scenarios, means that a quantitative comparison between regions or against the national objectives is not possible. Nevertheless, the report establishes a typology of regions and identifies policies that are common to all regions and those chosen in response to local characteristics. Certain guidelines could be applied by other regions of the same type, or could feed into discussions at national level. The report also indicates that the SRCAEs go beyond the competencies of the Regions, highlighting the role of local, national and European decision-making in the success of a regional energy transition. Particular attention was paid to the building and transport sectors, often identified as having the largest potential for reducing

    The characterisation of the stellar populations of ultra-compact HII (UCHII{}) regions is one of the key means of understanding the formation and evolution of massive stars. Adaptive Optics (AO) assisted near-infrared (NIR) observations provide sufficient resolution and sensitivity to detect such populations at moderate extinction values. We present NIR high-resolution observations of G61.48+0.09, a morphologically complex UCHII region with two components, whose accessible stellar content in the NIR has been widely studied before. A polarimetric map in the K' band, as well as H2(1-0) S(1) and Brγ narrow-band images of the region have been obtained with the AO system ALFA at the Calar Alto Observatory's 3.5 m telescope. We also present high-resolution imaging of the same region in the L' band with NAOS+CONICA at the VLT (UT4). The study of the nebular scattered light points to an internal-illumination model for the eastern component (B2). This model is confirmed by the detection of a point-like source in the L'-band data. In the western component (B1) the observed NIR colours of star 82 are consistent with spectral types BIa or early OV, while star 83 is reproduced by a B0V. Therefore, we identify these objects as the main detected ionising sources. However, in terms of illumination, our polarimetric map indicates that these two stars are not the dominating illuminators of the reflection nebula. Illumination from multiple sources (possibly still undetected) seems to influence the polarisation pattern for this component. Geometric considerations in the calculation of the energetics of this region, combined with the knowledge of the detected stellar content, also points to the presence of other ionising sources. Our study reinforces the hypothesis that there is a champagne flow towards the south-west part of the region.

    Pickett, Jolene S.

    2012-10-31

    The research carried out under the subject grant has provided insight into the generation of Electrostatic Solitary Waves (ESWs), which are nonlinear structures observed in space plasma data. These ESWs, appearing as pulses in the electric field time series data, represent the presence of several hundred meters to kilometer size positive potential structures, similar to champagne bubbles, where the electrons have been depleted, and which travel along Earth's magnetic field lines. The laboratory experiments carried out at the UCLA LAPD under the grant allowed us the opportunity to change various plasma and field conditions within the plasma device, and experiment with injection of suprathermal electron beams, in order to create ESWs. This then allowed us to determine the most likely method of generation of the ESWs. By comparing the properties of the ESWs observed in the LAPD to those observed in space and the plasma and field conditions under which those ESWs were observed in both locations, we were able to evaluate various ESW generation mechanisms. The findings of the laboratory experiments are that ESWs are generated through a lower hybrid instability. The ESWs observed in Earth's auroral current regions have similar characteristics to those generated by the laboratory when referenced to basic plasma and field characteristics, leading us to the conclusion that the lower hybrid drift instability is certainly a possibility for generation of the ESWs, at least in the auroral (northern/southern lights) regions. Due to space instrumentation insufficiencies and the limitations on telemetry, and thus poor time resolution, it is not possible to determine absolutely what generates these bubbles in space, but the laboratory experiments and supporting simulations have helped us to further our understanding of the processes under which they are generated. The public benefits from the findings of this research because the research is focused on current layers

    Quantum monodromy has a strong impact on the ro-vibrational energy levels of chain molecules whose bending potential energy function has the form of the bottom of a champagne bottle (i.e. with a hump or punt) around the linear configuration. NCNCS, cyanogen iso-thiocyanate, is a particularly good example of such a molecule and clearly exhibits a distinctive monodromy-induced dislocation of the energy level pattern at the bending-rotation energy at the top of the potential energy hump. Indeed, NCNCS [B. P. Winnewisser et al., Phys. Rev. Lett. 2005, 95, 243002] and the water molecule [N. F. Zobov et al., Chem. Phys. Lett. 2005, 414, 193-197] were the first two molecules for which experimental confirmation of quantum monodromy was obtained. We used the fast scan sub-millimetre spectroscopic technique (FASSST) to extend the measurements and spectral analysis to pure rotational transitions (end-over-end) in bending vibrational states lying well above the monodromy point. The analysis of 9204 lines assigned to 7 vibrational states, presented here, shows that the topological properties of the bending potential function are mapped onto every aspect of the ro-vibrational energy levels involving excitation of the quasi-linear bending vibration. In order to model the large amplitude dynamics of such a molecular system, and also to achieve some insight beyond satisfactory parameters for reproducing the spectrum, we used the generalized semi-rigid bender (GSRB) Hamiltonian, which is described in some detail. This Hamiltonian provides a good description of the energy levels over the seven bending states observed, coming close to experimental accuracy. Due to high J values of the measured rotational transitions (Jdipole moment components. High level ab initio calculations not only provided the molecular equilibrium structure of NCNCS, but also the electric dipole moment components mu(a) and mu(b) as functions of the large-amplitude bending coordinate.

  7. Book Review: Chemistry in Theatre. Insufficiency, Phallacy or Both

    Sterken, Christiaan; Djerassi, Carl

    2012-11-01

    This book deals with the question of what role a play, or the theatre, can fulfill as an educational or pedagogic tool in the broad scope of science learning and education. The book contains the texts of two of the author's recent plays, viz. Insufficiency and Phallacy. Carl Djerassi is a writer and an emeritus professor of chemistry at Stanford University. He has published short stories, poetry, some novels and several "science-in-theatre" plays. Almost one fifth of this slim booklet is occupied by Djerassi's preface that is, in its own right, a most useful essay worth reading by any student of the exact sciences. Djerassi's point is that most of the modern science plays have a didactic component, and aim to illustrate - through the medium of theatre - what science or scientists are all about. To make such plays available to a broad audience, he advocates the production of readable books written in play format. The strong point of such plays is the dialogue format - as was already very well known by forerunners like Galileo Galilei with his Dialogue Concerning the Two Chief World Systems, published in 1632. Djerassi does not tell what his characters do, but he emphasises how and why they do some specific thing. Insufficiency is about the chemistry of champagne bubbles (coined bubbleology, i.e., the science of champagne or beer bubbles), in a scientific academic context dealing with tenure and fashion. The story clearly shows how the life of a young tenure-seeking scientist develops under the strong interlock of forced - but also of voluntary - overwork that leads to tenure (in turn accompanied by an increase in material security). But it also mentions the self-imposed and seemingly unescapable treadmill of success and scientific achievement that comes with tenure. The play also deals with fashion in science via the simplistically coined term bubbleology, and the author shows that the actual implications of this "science" actually even reach to cosmology. The

  8. NOGENT, just another power plant - but so close to Paris

    International Nuclear Information System (INIS)

    54 PWR type production units are today operating in France. Between 1980 and 1981, 11 units were under construction including both Nogent PWR-1300 units. The increasing consumption in the lie de France region in the early eighties affected the choice of the site so close to Paris on the banks of the Seine, not more than 95 km from Notre Dame Cathedral. In February 1975, the Champagne-Ardenne Regional Council gave a favourable opinion to installation of a nuclear power plant in the Marne or Seine valley. The location of the plant thus offered an economic opportunity to a region in which second homes were growing at the expense of primary residences. The Nogent plant is not the only one to be situated close to a city. One of the major concerns was related to the fact that the power plant was located on the banks of the river supplying Paris with drinking water. The plant has a geographical location whose political and media implications are Parisian, and thus national. Therefore, the plant was equipped with a public information centre which opened on 1st January 1988, and which in general receives some 20 000 visitors annually. It is located outside the controlled areas of the plant and access is free to all visitors. It gives a permanent exhibition on nuclear power and the Nogent plant in particular. Its auditorium can seat 120 for conferences and films on all subjects concerning nuclear power. The construction of the Information Centre cost 6 million francs. The visitors mainly come from the Paris region : many teachers bring their classes to find out about our installations. The EDF Divisions bring many notable visitors : foreign ministers, captains of industry, and any foreign nuclear company on an information visit to France. The opposition to Nogent comes mainly from Paris, in 1979 of a Committee for nuclear alternatives called Stop-Nogent was established. 1982,1983,1984 and 1985 were marked by strong action and local disputes, reported in the press (sabotage

    Accurate rainfall measurement is a fundamental requirement in a broad range of applications including flood risk and water resource management. The most widely used method of measuring rainfall is the rain gauge, which is often also considered to be the most accurate. In the context of hydrological modelling, measurements from rain gauges are interpolated to produce an areal representation, which forms an important input to drive hydrological models and calibrate rainfall radars. In each stage of this process another layer of uncertainty is introduced. The initial measurement errors are propagated through the chain, compounding the overall uncertainty. This study looks at the fundamental source of error, in the rainfall measurement itself; and specifically addresses the largest of these, the systematic 'wind-induced' error. Snowfall is outside the scope. The shape of a precipitation gauge significantly affects its collection efficiency (CE), with respect to a reference measurement. This is due to the airflow around the gauge, which causes a deflection in the trajectories of the raindrops near the gauge orifice. Computational Fluid-Dynamic (CFD) simulations are used to evaluate the time-averaged airflows realized around the EML ARG100, EML SBS500 and EML Kalyx-RG rain gauges, when impacted by wind. These gauges have a similar aerodynamic profile - a shape comparable to that of a champagne flute - and they are used globally. The funnel diameter of each gauge, respectively, is 252mm, 254mm and 127mm. The SBS500 is used by the UK Met Office and the Scottish Environmental Protection Agency. Terms of comparison are provided by the results obtained for standard rain gauge shapes manufactured by Casella and OTT which, respectively, have a uniform and a tapered cylindrical shape. The simulations were executed for five different wind speeds; 2, 5, 7, 10 and 18 ms-1. Results indicate that aerodynamic gauges have a different impact on the time-averaged airflow patterns

    The Piedra Berroqueña region occupies an area of approximately 4000 km2 in the Sierra de Guadarrama, Spanish Central System, the centre of the Iberian Peninsula. This region has provided most of the building granites used in Madrid and surrounding provinces. Traditional methods of cutting and carving stone have been preserved and it is easy to locate historic quarries in its landscape in addition to mechanized quarries with large reserves of this dimension stone that is exported worldwide in the form of blocks or slabs with different finishes. The Piedra Berroqueña has been used as a building stone since before the Romans. Petrophysical and durability characteristics have allowed to endure monuments as representative as The Royal Monastery of San Lorenzo del Escorial (1563-1584), del Sol Gate (1857-1862), Royal Palace (1738-1764), Alcalá Gate (1770-1778) or Prado Museum (1785-1808) in Madrid, Spain. Also the Piedra Berroqueña is part of most residential buildings and streets of this city, as well as modern buildings around the world, such as airport terminals in Athens, Cork, the British consulate in Hong Kong and headquarters of banks in Jakarta, among others. Piedra Berroqueña province is presented in this abstract, which has many granite quarries with common characteristics such as their grey tones and the presence of darker enclaves "Gabarros or negrones". In the Piedra Berroqueña province four main types of granite can be distinguish: Peraluminous granites; with biotite and occasional cordierite, whose most representative historic quarries are in Alpedrete, Colmenar Viejo, El Boalo, El Berrocal and Collado Mediano. Biotite granites with occasional amphibole are present in historic quarries in El Berrueco, Lozoyuela-Navas-Sieteiglesias and Pelayo de la Presa, among others.

    The french agriculture is a sector particularly concerned by climate change: the scale of the already observed impacts and the expected climatic evolutions prevent any hesitation on the necessity of an adaptation of agriculture. This assessment is simultaneously shared by the scientific, political as well as the economic communities. However, a generalized and organized movement of adaptation of agriculture has difficulty in emerging in France and maybe in other countries, while past decades have seen the development of research projects and publications on the adaptation to climate change. Two parallel initiatives have been run in France over the past 5 years, that happen to share the same name while not involving the same actors: an observatory of climate change and agriculture functioning (ORACLE: Observatoire Régional sur l'Agriculture et le Changement Climatique), and a nationally funded research project that explores with various tools risks and opportunities for agro-ecosystems in the future in France (ORACLE: Opportunities and Risks of Agrosystems & forests in response to CLimate, socio-economic and policy changEs in France). The Observatory is carrying on a regional analysis of historical trends of both climatic and agricultural variables. It has for ambition to help the agricultural world to better integrate the evolution of climate into its decision-making, for purposes of adaptation as well as mitigation. The observatory is run since year 2011 in the Poitou-Charentes region and is now being implemented in other regions in France (Aquitaine, Pays de la Loire, Champagne Ardennes, Normandie). The research project has looked into the impacts of various scenarios of climate change through the use of various techniques : mechanistic models (Calvet et al. 2013, Wu et al. 2016) and eco-climatic indicators (Caubel et al. 2015). Informations regarding risks and opportunities for large crops in France is in the process being assessed though those tools and

    To date, there are only a few known heterotrophic arsenite oxidizers and arsenate reducers. They utilize organic compounds as their carbon source and/or as important electron donors in the transfer arsenic in high temperature environments. Arsenic in hydrothermal vent systems can be immobilized at low temperatures through (ad)sorption on iron oxide and other iron-bearing minerals. Interactions with sulfur species can also affect the redox state of arsenic species. A better understanding of microbially-catalyzed reactions involving carbon, arsenic, iron and sulfur would provide constraints on the mobility of arsenic in a wide variety of natural and engineered systems. The aim of this study is to establish links between microbial distribution and in situ Fe-S-As cycling processes in a shallow-sea hydrothermal vent system. We investigated three shallow-sea hydrothermal vents, Champagne Hot Spring (CHS), Soufriere Spring (SOU) and Portsmouth Spring (PM), located off the western coast of Dominica, Lesser Antilles. CHS and SOU are characterized by moderate temperatures (46oC and 55oC, respectively), and PM is substantially hotter (~90-111 oC). Two sediment cores (one close to and one far from the thermal source) were collected from CHS and from SOU. Porewaters in both background cores had low concentrations of arsenic (mostly As3+, to a lesser extent As5+, DMA, MMA) and ferrous iron. The arsenic concentrations (predominantly As3+) in the CHS high temperature core were 30-90 nM, tracking with dissolved iron. Similar to CHS, the arsenic concentration in the SOU high temperature core was dominated by As3+ and controlled by ferrous iron. However, the arsenic concentration at SOU is comparatively higher, up to 1.9 mM. At the hotter and deeper PM site, highly elevated arsenic levels (1-2.5 mM) were measured, values that are among the highest arsenic concentrations ever reported in a marine hydrothermal system. Several autotrophic and heterotrophic media at two pHs (5.5 and 8

  18. Results from the geological surveys carried out in the Bure laboratory's drifts

    International Nuclear Information System (INIS)

    Document available in extended abstract form only. After the government's authorization to build and operate an underground laboratory, Andra started the investigation works in November 99 on the Meuse/Haute-Marne URL site. The Meuse/Haute-Marne URL is located at the border of the Champagne-Ardenne and Lorraine regions, on the township of Bure in the Callovo-Oxfordian clay-rich rock. At this place, the layer is about 135 m-thick and lies at a depth of 417 m to 552 m. The construction of the underground installations started in August 2000 with the sinking of the main shaft and the first phase of diggings was completed on the 27 April 2006 when it linked up with the south drift of the laboratory. The laboratory consists in two vertical shafts crossing the 505-m thick sedimentary cover and two levels of experimental drifts dug in Callovo-Oxfordian formation. The first experimental drift dug at -445 m with a drill-and-blast method with steps of 2.4 m. The technical and experimental drifts at the main level (-490 m of depth) were dug with a hydraulic stone crusher. The aims of the geological surveys carried out during the drifts digging are to observe the lateral variation of the lithology, if there is one, to confirm the absence of fault and the geometry of the argillites formation. These works should also allow to characterize the natural or inducted fracturing (EDZ - Excavation Damaged Zone) induced by the digging by a sedimentary and structural follow-up. The EDZ characterization has been established from the geological survey of the drift face and sidewalls carried out from 1 to 5 meters in the drifts, and completed by the structural analysis of the cores of the boreholes drilled for the experimentations' equipments. After the safe keeping of the front, the geological team goes down to carry out the survey which consists in a lithologic and sedimentary mapping, a structural survey for the understanding of joints distribution and EDZ characterization, and

    influence of regional subsidence is superimposed on the successions of deposits, linked to sealevel changes. These two factors control the accomodation and the hydrodynamic conditions of the basin. Tectonic activity can obliterate the role of eustatism to the extent of preventing any deposit, and entire sedimentary sequences may then not be expressed locally, as is the case for the Humphriesianum zone in the Poitou and Berry regions. On the other hand, a speeding up of the subsidence of the Marty Trough occurred during the highstand interval in the Lotharingian (Sequence 3, causing the deposition of back basin clays, thus situating the maximum paleodepth exceptionally at the top of the sequence underneath a nonerosive discontinuity. A contrast can also be seen between the marly series of the Upper Pliensbachian, such as the Bathonian, and the condensed limestone series of the Lower and Middle Bajocian. The installation of the carbonate platform in the Aalenian-Lower Bajocian (platform with an accumulation of bioclast sands of the keep-up carbonate platformtype, Sarg, 1989, with already a first glimpse of the upermost Toarcian (micritic limestone platform with gryphites, of the catch-up carbonate platformtype, according to Sarg, 1989, was probably caused by a great slowing down of subsidence. The same pattern can be found in the regional Callovian with periods of erosion or nondeposition. We are led to highlight three periods of tectonic activity in the Couy area (Lotharingian, Aalenian-Bajocian, Callovian, which do not always correspond to the tendencies described in other paleogeographic domains, for example such as Champagne in the Middle Jurassic (Guillocheau, 1991. A sequential analysis of the Couy borehole has revealed 18 sequences in the Lower Jurassic and part of the Middle Jurassic. In the Lower Jurassic, 11 characterized sequences (the last one transiting into the MiddleJurassic are similar to the ones proposed by Haq et al. (1988 , which for Western Europe must
