    The Marseille-Aubagne Basins, which extend from Marseille to Roquevaire, occupy more than fifty per cent of the Marseille-Aubagne geological map, with approximately one million people living in this area. Despite this geological importance they are still poorly known. The first synthetic view was delivered in the 1935 geological map. Studied by Bonifay, the Quaternary deposits have been included in the 1969 geological map. Nevertheless, the Oligocene formations remained unmodified until Nury, who provided a lot of very detailed stratigraphic data. New studies have been carried out in the frame of the third issue of the 1:50,000 geological map. These studies allow us to distinguish between three different basins: the ''Jarret basin'' in the northern part, the ''Prado basin'' in the southwestern part and the ''Aubagne basin'' in the eastern part. Each of them contains its own stratigraphic succession, including several formations from the Rupelian to the Chattian. Globally, the Lower to Upper Rupelian formations are tectonically deformed, whilst deposits from the Latest Rupelian to the Latest Chattian show only slight deformation. Thus, two main geodynamic stages have been distinguished: the first beginning with the Early Oligocene extensive regime leading to the opening of NNE-SSW troughs all over the European platform and, the second, beginning with a NNW-SSE extensive regime coeval with the Western Mediterranean rifting. The key point that separates these two stages from each other is a possible Late Rupelian compressive regime. To sum up, this basin can be considered as a natural archive for the Oligocene events. Therefore, these basins should be considered as master pieces for the Oligocene palaeogeographic and geodynamic reconstructions. (Author)

    OBJECTIVES: This study evaluated the usefulness of vending machines in providing injection drug users with access to sterile syringes in Marseille, France. METHODS: Self-administered questionnaires were offered to 485 injection drug users obtaining syringes from 32 pharmacies, 4 needle exchange programs, and 3 vending machines. RESULTS: Of the 343 respondents (response rate = 70.7%), 21.3% used the vending machines as their primary source of syringes. Primary users of vending machines were more likely than primary users of other sources to be younger than 30 years, to report no history of drug maintenance treatment, and to report no sharing of needles or injection paraphernalia. CONCLUSIONS: Vending machines may be an appropriate strategy for providing access to syringes for younger injection drug users, who have typically avoided needle exchange programs and pharmacies.

    Help of satellite radar interferometry for urban subsidence observation has been demonstrated for several years now. This monitoring tool is able to provide an assessment of the ground motion with a millimetric accuracy and a large spatial coverage. We present here a result of this technique applied to the monitoring of a small area : the shopping centre complex and cinema multiplex in Marseilles, France. This construction work was one of the most important construction site of this last few years in France. Inaugurated in October, 1997, the multiplex had to close 6 of its 15 cinemas five months later because of collapsing risks due to important ground movements. It has been totally closed in July, 1999. The multiplex building demolition is currently under way. Finally, this "flop" represents a cost of 30 millions euros. 14 ERS images acquired between 1992 and 2000 had been processed in order to produce a set of 105 differential interferograms. We performed a recursive correction of orbital and topographic fringes using a FFT computation and a Digital Elevation Model provided by the French National Institute (IGN). The analysis of the interferograms series has allowed to detect unambiguously a signature of few pixels corresponding to the ground movement. From this study, we observed a ground deformation during 1997 to 1998, an overall stability during late 1998 to 1999 and again a deformation during late 1999 to 2000. This study shows that, in specific cases, traditional InSAR is able to provide valuable information on very localised ground deformation. It also shows the interest of a comprehensive study of the full ERS archive of this site in order to assess the stability of the ground before, when no ground-based measurements were available, during, and after the construction works.

    We characterize and decipher the resistome and the virulence factors of Shewanella algae MARS 14, a multidrug-resistant clinical strain using the whole genome sequencing (WGS) strategy. The bacteria were isolated from the bronchoalveolar lavage of a hospitalized patient in the Timone Hospital in Marseille, France who developed pneumonia after plunging into the Mediterranean Sea. The genome size of S. algae MARS 14 was 5,005,710 bp with 52.8% guanine cytosine content. The resistome includes members of class C and D beta-lactamases and numerous multidrug-efflux pumps. We also found the presence of several hemolysins genes, a complete flagellum system gene cluster and genes responsible for biofilm formation. Moreover, we reported for the first time in a clinical strain of Shewanella spp. the presence of a bacteriocin (marinocin). The WGS analysis of this pathogen provides insight into its virulence factors and resistance to antibiotics.

    An Oligocene tectonic event has been suspected as the origin of thrusts and folds in several Oligocene troughs and basins of Provence, including the Marseille-Aubagne basins. Deformations are generally assumed to be to a post Oligocene extensional event. The Marseille-Aubagne basins are geographically and stratigraphically separated into three basins (Jarret, Prado and Aubagne) with each of them exhibiting their own sedimentary succession. However, each of the successions includes two main units: - The lower unit which includes several formations attributed to the Rupelian age. All of these sediments are strongly or slightly deformed depending on their location with respect to the main faults. - The upper unit which includes formations of mainly Chattian age. They are undeformed or slightly deformed. Geological sections across the southern Prado basin show a succession of anticlines and synclines. Additionally the thrusting of the Carpiagne massif over the Prado basin has been evidenced since 1952. These deformations are here related to a compressional event According to palaeontological data, the latest deformed strata are ascribed to the Late Rupelian, whereas the earliest undeformed strata are ascribed to the Latest Rupelian. This is in accordance with age determinations on detrital zircons extracted from the latest deformed sandstone, and from the youngest age of detrital zircons from the undeformed sandstone. Thus, the stratigraphic limit between the deformed and undeformed formations should be set around the Rupelian / Chattian limit (28.1 Ma) according to the latest chronostratigraphic chart. Finally, we discuss correlations with similar events occurring around the Mediterranean area. (Author)

    An inventory describing the fluxes of volatile organic compounds (VOCs), isoprene and monoterpenes, and other VOCs (OVOCs) from the biosphere to the atmosphere, has been constructed within the framework of the ESCOMPTE project (fiEld experimentS to COnstrain Models of atmospheric Pollution and Transport of Emissions). The area concerned, located around Berre-Marseilles, is a Mediterranean region frequently subject to high ozone concentrations. The inventory has been developed using a fine scale land use database for the year 1999, forest composition statistics, emission potentials from individual plant species, biomass distribution, temperature and light intensity. The seasonal variations in emission potentials and biomass were also taken into account. Hourly meteorological data for 1999 were calculated from ALADIN data and these were used to predict the hourly isoprene, monoterpene and OVOC fluxes for the area on a 1 kmx1 km spatial grid. Estimates of annual biogenic isoprene, monoterpene and OVOC fluxes for the reference year 1999 were 20.6, 38.9 and 13.3 kt, respectively, Quercus pubescens, Quercus ilex, Pinus halepensis and garrigue vegetation are the dominant emitting species of the area. VOC emissions from vegetation in this region contribute approximately 94% to the NMVOC (non-methane volatile organic compounds) of natural origin and are of the same order of magnitude as NMVOC emissions from anthropogenic sources. These results complete the global ESCOMPTE database needed to make an efficient strategy for tropospheric ozone reduction policy.

    To assess HPV prophylactic vaccine coverage among French high school and university students as well as their level of education about this vaccine. An anonymous survey was conducted among 2500 high school and university students from the area of Marseilles, France, from December 2009 to April 2010. A total of 2018 questionnaires were collected (80.7% participation rate). Mean age of participants was 20 years (range, 15-45 years). Only 671 (35.4%) participants reported having been vaccinated against HPV, of whom 510 (73.4%) had completed the three injections scheme. Practice of cytological cervical cancer screening was not significantly influenced by vaccination status. Thus, 578 (45.2%) participants who had not been vaccinated already had had a cervical cytology performed, versus 295 (43.3%) vaccinated ones (P=0.445). Among those not being vaccinated, 671 (49.8%) fulfilled criteria for a catch-up vaccination, of whom only 325 (48.4%) agreed for such a catch-up. Main reasons given for refusal for a catch-up vaccination were the lack of information about HPV vaccine and fear of side effects. In total, 1722 (90%) considered themselves as educated about the HPV vaccine. Source of education was attributed to doctors and media by 54.4% and 53.7% of participants, respectively. Educational role attributed to school and university was poor (3.4%). Despite apparent satisfactory level of education, HPV prophylactic vaccine coverage among high school and university students appears to be insufficient. Copyright © 2011 Elsevier Masson SAS.

    With the aim to identify at-risk individuals among a cohort of international travellers, 3442 individuals who sought advice at Marseille travel health centre in 2009 were prospectively included. Demographics, travel characteristics, chronic medical conditions, vaccinations and antimalarial chemoprophylaxis were documented. Chronic medical conditions were reported by 11% of individuals, including hypertension (39%), asthma (20%), thyroid disease (15%) and depression (13%). 4% reported taking a daily medication, and psychotropic and cardiovascular medications were the most commonly used. Older travellers (≥60 years) accounted for 10% of the travellers and the prevalence of chronic medical conditions was 27% in this group. Individuals aged 15 years or less accounted for 13% of the travellers. Age, last minute travel (17%) and neurological and psychiatric diseases were the most frequent factors that influenced Yellow fever vaccination and malaria chemoprophylaxis, with more than one tenth of the travellers reporting at least one risk factor for which adjusted advice may be necessary. Migrants visiting their relatives in their origin country accounted for 14% of travellers and 73% of this group travelled with their family including young children. We demonstrate that a significant proportion of travellers are at-risk (43%) because of their travel conditions (VFR), their age, or their health status, and should be targeted for risk reduction strategies.

    In Marseille, southeastern France, HIV prevention programs for injection drug users (IDUs) simultaneously include access to sterile syringes through needle exchange programs (NEPs), legal pharmacy sales and, since 1996, vending machines that mechanically exchange new syringes for used ones. The purpose of this study was to compare the characteristics of IDUs according to the site where they last obtained new syringes. During 3 days in September 1997, all IDUs who obtained syringes from 32 pharmacies, four NEPs and three vending machines were offered the opportunity to complete a self-administered questionnaire on demographics, drug use characteristics and program utilization. Of 485 individuals approached, the number who completed the questionnaire was 141 in pharmacies, 114 in NEPs and 88 at vending machines (response rate = 70.7%). Compared to NEP users, vending machine users were younger and less likely to be enrolled in a methadone program or to report being HIV infected, but more likely to misuse buprenorphine. They also had lower financial resources and were less likely to be heroin injectors than both pharmacy and NEP users. Our results suggest that vending machines attract a very different group of IDUs than NEPs, and that both programs are useful adjuncts to legal pharmacy sales for covering the needs of IDUs for sterile syringes in a single city. Assessment of the effectiveness and cost-effectiveness of combining such programs for the prevention of HIV and other infectious diseases among IDUs requires further comparative research.

    Full Text Available We decipher the resistome of Chryseobacterium indologenes MARS15, an emerging multidrug-resistant clinical strain, using the whole genome sequencing strategy. The bacterium was isolated from the sputum of a hospitalized patient with cystic fibrosis in the Timone Hospital in Marseille, France. Genome sequencing was done with Illumina MiSeq using a paired-end strategy. The in silico analysis was done by RAST, the resistome by the ARG-ANNOT database and detection of polyketide synthase (PKS by ANTISMAH. The genome size of C. indologenes MARS15 is 4 972 580 bp with 36.4% GC content. This multidrug-resistant bacterium was resistant to all β-lactams, including imipenem, and also to colistin. The resistome of C. indologenes MARS15 includes Ambler class A and B β-lactams encoding blaCIA and blaIND-2 genes and MBL (metallo-β-lactamase genes, the CAT (chloramphenicol acetyltransferase gene and the multidrug efflux pump AcrB. Specific features include the presence of an urease operon, an intact prophage and a carotenoid biosynthesis pathway. Interestingly, we report for the first time in C. indologenes a PKS cluster that might be responsible for secondary metabolite biosynthesis, similar to erythromycin. The whole genome sequence analysis provides insight into the resistome and the discovery of new details, such as the PKS cluster.

    Our study highlights the Lagrangian transport of solid particles discharged at the Marseille Wastewater Treatment Plant (WWTP), located at Cortiou on the southern coastline. We focused on episodic situations characterized by a coastal circulation pattern induced by intrusion events of the Northern Current (NC) on the continental shelf, associated with SE wind regimes. We computed, using MARS3D-RHOMA and ICHTHYOP models, the particle trajectories from a patch of 5.104 passive and conservative fine particles released at the WWTP outlet, during 2 chosen representative periods of intrusion of the NC in June 2008 and in October 2011, associated with S-SE and E-SE winds, respectively. Unexpected results highlighted that the amount of particles reaching the vulnerable shorelines of both northern and southern bays accounted for 21.2% and 46.3% of the WWTP initial patch, in June 2008 and October 2011, respectively. Finally, a conceptual diagram is proposed to highlight the mechanisms of dispersion within the bays of Marseille of the fine particles released at the WWTP outlet that have long been underestimated.

    Seawater samples were collected in surface waters (2 and 5 m depths) of the Bay of Marseilles (Northwestern Mediterranean Sea; 5°17'30'' E, 43°14'30'' N) during one year from November 2007 to December 2008 and studied for total organic carbon (TOC) as well as chromophoric dissolved organic matter (CDOM) optical properties (absorbance and fluorescence). The annual mean value of surface CDOM absorption coefficient at 350 nm [aCDOM(350)] was very low (0.10 ± 0.02 m-1) with in comparison to values usually found in coastal waters, and no significant seasonal trend in aCDOM(350) could be determined. By contrast, the spectral slope of CDOM absorption (SCDOM) was significantly higher (0.023 ± 0.003 nm-1) in summer than in fall and winter periods (0.017 ± 0.002 nm-1), reflecting either CDOM photobleaching or production in surface waters during stratified sunny periods. The CDOM fluorescence, assessed through excitation emission matrices (EEMs), was dominated by protein-like component (peak T; 1.30-21.94 QSU) and marine humic-like component (peak M; 0.55-5.82 QSU), while terrestrial humic-like fluorescence (peak C; 0.34-2.99 QSU) remained very low. This reflected a dominance of relatively fresh material from biological origin within the CDOM fluorescent pool. At the end of summer, surface CDOM fluorescence was very low and strongly blue shifted, reinforcing the hypothesis of CDOM photobleaching. Our results suggested that unusual Rhône River plume eastward intrusion events may reach Marseilles Bay within 2-3 days and induce local phytoplankton blooms and subsequent fluorescent CDOM production (peaks M and T) without adding terrestrial fluorescence signatures (peak C). Besides Rhône River plumes, mixing events of the entire water column injected humic (peaks C and M) CDOM from the bottom into the surface and thus appeared also as an important source of CDOM in surface waters of the Marseilles Bay. Therefore, the assessment of CDOM optical properties, within the

    To assess risk factors for respiratory tract infection symptoms and signs in sheltered homeless people in Marseille during the winter season, including pathogen carriage. Data on 479 male participants within two shelters who completed questionnaires and a total of 950 nasal and pharyngeal samples were collected during the winters of 2015-2017. Respiratory pathogen carriage including seven viruses and four bacteria was assessed by quantitative PCR. The homeless population was characterized by a majority of individuals of North African origin (300/479, 62.6%) with a relatively high prevalence of chronic homelessness (175/465, 37.6%). We found a high prevalence of respiratory symptoms and signs (168/476, 35.3%), a very high prevalence of bacterial carriage (313/477, 65.6%), especially Haemophilus influenzae (280/477, 58.7%), and a lower prevalence of virus carriage (51/473, 10.8%) with human rhinovirus being the most frequent (25/473, 5.3%). Differences were observed between the microbial communities of the nose and throat. Duration of homelessness (odds ratio (OR) 1.77, p 0.017), chronic respiratory diseases (OR 5.27, p respiratory symptoms and signs. A strong association between virus (OR 2.40, p 0.012) or Streptococcus pneumoniae (OR 2.32, p 0.014) carriage and respiratory symptoms and signs was also found. These findings allowed identification of the individuals at higher risk for contracting respiratory tract infections to better target preventive measures aimed at limiting the transmission of these diseases in this setting.

    Background In France, there was a reluctance to accept vaccination against the A/H1N1 pandemic influenza virus despite government recommendation and investment in the vaccine programme. Methods and Findings We examined the willingness of different populations to accept A/H1N1vaccination (i) in a French hospital among 3315 employees immunized either by in-house medical personnel or mobile teams of MDs and (ii) in a shelter housing 250 homeless persons. Google was used to assess the volume of enquiries concerning incidence of influenza. We analyzed the information on vaccination provided by Google, the website of the major French newspapers, and PubMed. Two trust Surveys were used to assess public opinion on the trustworthiness of people in different professions. Paramedics were significantly more reluctant to accept immunisation than qualified medical staff. Acceptance was significantly increased when recommended directly by MDs. Anecdotal cases of directly observed severe infections were followed by enhanced acceptance of paramedical staff. Scientific literature was significantly more in favour of vaccination than Google and French newspaper websites. In the case of the newspaper websites, information correlated with their recognised political reputations, although they would presumably claim independence from political bias. The Trust Surveys showed that politicians were highly distrusted in contrast with doctors and pharmacists who were considered much more trustworthy. Conclusions The low uptake of the vaccine could reflect failure to convey high quality medical information and advice relating to the benefits of being vaccinated. We believe that the media and internet contributed to this problem by raising concerns within the general population and that failure to involve GPs in the control programme may have been a mistake. GPs are highly regarded by the public and can provide face-to-face professional advice and information. The top-down strategy of vaccine

Anecdotal cases of directly observed severe infections were followed by enhanced acceptance of paramedical staff. Scientific literature was significantly more in favour of vaccination than Google and French newspaper websites. In the case of the newspaper websites, information correlated with their recognised political reputations, although they would presumably claim independence from political bias. The Trust Surveys showed that politicians were highly dis-trusted in contrast with doctors and pharmacists who were considered much more trustworthy. CONCLUSIONS: The low uptake of the vaccine could reflect failure to convey high quality medical information and advice relating to the benefits of being vaccinated. We believe that the media and internet contributed to this problem by raising concerns within the general population and that failure to involve GPs in the control programme may have been a mistake. GPs are highly regarded by the public and can provide face-to-face professional advice and information. The top

    The French energy system, like that of most energy-importing nations, was profoundly transformed by the first oil shock. But France was more vulnerable than any other industrialized country besides Japan to oil supply disruption: in 1973, the nation imported 77 percent of total primary energy requirements of 7.6 EJ, and 98 percent of its petroleum. Two imperatives have since formed the 'French response' to the threat of external energy supply disruptions: augmentation of the rate of energy self-sufficiency, and minimization of major macroeconomic dislocations. These two objectives displaced a high priority in France in the early 1970s - protection of the natural environment. Because France has embraced nuclear power, it is often viewed by its European neighbors as having feeble ecological sensibility. At that time, France had a rather advanced policy in this field: sulfur emissions laws were enacted in 1967 and a Ministry of Environment was created in January 1971. Now that environmental concerns have re-emerged as an important force, France finds itself with a plausible greenhouse response in a mix of policies - without environmental protection having been the objective envisioned

    The grandeur of the nation is the most important national concern in the France of the Fifth Republic. National independence and maximum world status have been (and still are) characteristic imperatives of French policy. Any asset or resource which promises to strengthen the nation, which seems suitable for improving the global status and glory of France, becomes a worthwhile policy device. Of course, the sots incurred in the pursuit of these objectives are frequently the subject of critical discussion, but all in all these costs are accepted. This has been the case with numerous prestige projects including the French nuclear deterrent, the force de frappe. This paper reports that an analysis of the French ambition to possess nuclear weapons must begin with the complete loss of world status which France suffered as a consequence of World War II. Throughout the post-war period, French political leaders have concentrated their efforts on reversing this loss of status and on preventing a similar occurrence

  5. Vertical Structure of the Urban Boundary Layer over Marseille Under Sea-Breeze Conditions

    During the UBL-ESCOMPTE program (June July 2001), intensive observations were performed in Marseille (France). In particular, a Doppler lidar, located in the north of the city, provided radial velocity measurements on a 6-km radius area in the lowest 3 km of the troposphere. Thus, it is well adapted to document the vertical structure of the atmosphere above complex terrain, notably in Marseille, which is bordered by the Mediterranean sea and framed by numerous massifs. The present study focuses on the last day of the intensive observation period 2 (26 June 2001), which is characterized by a weak synoptic pressure gradient favouring the development of thermal circulations. Under such conditions, a complex stratification of the atmosphere is observed. Three-dimensional numerical simulations, with the Méso-NH atmospheric model including the town energy balance (TEB) urban parameterization, are conducted over south-eastern France. A complete evaluation of the model outputs was already performed at both regional and city scales. Here, the 250-m resolution outputs describing the vertical structure of the atmosphere above the Marseille area are compared to the Doppler lidar data, for which the spatial resolution is comparable. This joint analysis underscores the consistency between the atmospheric boundary layer (ABL) observed by the Doppler lidar and that modelled by Méso-NH. The observations and simulations reveal the presence of a shallow sea breeze (SSB) superimposed on a deep sea breeze (DSB) above Marseille during daytime. Because of the step-like shape of the Marseille coastline, the SSB is organized in two branches of different directions, which converge above the city centre. The analysis of the 250-m wind fields shows evidence of the role of the local topography on the local dynamics. Indeed, the topography tends to reinforce the SSB while it weakens the DSB. The ABL is directly affected by the different sea-breeze circulations, while the urban effects appear

  8. Escompte Pre-modelling Studies In The Marseille Area.

    Meleux, F.; Rosset, R.

    On June and July 2001, the campaign ESCOMPTE took place in the Marseille area in southern of France, with the aim of generating a detailed 3-D data base for the study of dynamics and chemistry of high pollution events so as to validate and improve air quality models. Previous to this field experiment, a pre-modelling exercise has been performed to document the dynamic interactions between sea and land breezes and orographics flows over this complex topographical area. This study was carried out using a nesting procedure at local and regional scales using the MESO-NH model (jointly developed by Laboratoire d'Aérologie and Meteofrance at Toulouse). Tracers emitted at various locations in the Marseille and Etang de Berre areas were first fol- lowed, then in a second step, full chemistry simulations have been run for two selected periods on June and July 1999, quite similar to the meteorological situations met dur- ing the IOP2a and the IOP4 in the 2001 campaign. The performance of the model has been assessed by comparing measured data with simulated data for meteorological pa- rameters and ozone. The general ability of the model to correctly simulate these two situations allows to further study ozone plume developments in more details. In par- ticular, these studies bear upon the relative roles of O3 transport versus O3 chemical production, as a function of distance within the plume to anthropogenic emissions and biogenic emissions, together with ozone daily variations and peak values observed at rural sites.

Avec l’installation des descendants des dynasties archontales chiotes s’initie un processus de cristallisation communautaire idiosyncrasique : d’un côté, la Génération archontale (1825-1875 pose dans son cadre principal d’identification – la Communauté à Marseille — ses représentations groupales de longue durée (religion, langue, parentèle, auto-administration communautaire, de l’autre, elle actualise ces schémas par un réinvestissement sélectif qui fait donc coexister diacritique et conformité identitaire.This historical perspective discusses the settlement of Greeks in Marseille, France, from the late-eighteenth century to the first decade of the 1900s. During this period, the sociological bonds between the different Greek embryonic minorities, suggest a nuclear colony. The wave of new-comers from the Island of Chios precipitated some major changes in the Marseille Greek’s social morphology: they introduced a social crystallization process through which the archontal Generation (1825-1875 incorporated the long-term representations of the group (religion, language, self-administration policy and kinship, into its main identification frame, the Community. At the same time, this Generation elaborated its own social model through a selective acquisition of local French representations and values. In this way, the Greek Community building in Marseille suggested a pattern where coexisted diacritical and congruent identities.

  10. Memory and Forgetting on the National Periphery: Marseilles and the Regicide of 1934

    Full Text Available The assassination of the King of Yugoslavia, Alexander Ist by Croatian terrorists during a state visit to Marseilles on 9 October 1934 is commemorated by a modest plaque on the Canebière and a little known monument outside the Préfecture. Although the histories of the period cite the event in passing, it is treated as a footnote in the political history of France and has been all but erased from the memory of the city. While there are good reasons for forgetting the episode – regicide does no favours for the reputation of a host nation or city and the French Foreign Minister Louis Barthou was accidentally shot by the French police – the double killing had multiple ramifications for France's interior and foreign affairs during the rise of fascism in Europe. It advanced the career of future Vichy Prime Minister Pierre Laval, who replaced Barthou as Foreign Minister, while French efforts to contain the threat of German expansionism by forging alliances with the Central European powers died with Barthou; King Alexander Ist's successor moved Yugoslavia into the camp of the Axis powers. Geopolitically, the system of collective security forged at Versailles collapsed in the wake the assassination. The incident in Marseilles highlights political tensions in France in the troubled inter-war years leading up to the emergence of the Front Populaire. It reveals the memorial agencies of core and periphery engaged in a struggle over the rights to remembrance. Above all, it poses the problem of the preservation of peripheral and traumatic episodes in collective memory and suggests that political violence constitutes a social periphery of its own, contributing to Marseille's "mauvaise réputation" as the French capital's negative, meridional 'other'.

    The Town Energy Balance (TEB) model, which parameterizes the local-scale energy and water exchanges between urban surfaces and the atmosphere by treating the urban area as a series of urban canyons, coupled to the Interactions between Soil, Biosphere, and Atmosphere (ISBA) scheme, was run in offline mode for Marseille, France. TEB's performance is evaluated with observations of surface temperatures and surface energy balance fluxes collected during the field experiments to constrain models of atmospheric pollution and transport of emissions (ESCOMPTE) urban boundary layer (UBL) campaign. Particular attention was directed to the influence of different surface databases, used for input parameters, on model predictions. Comparison of simulated canyon temperatures with observations resulted in improvements to TEB parameterizations by increasing the ventilation. Evaluation of the model with wall, road, and roof surface temperatures gave good results. The model succeeds in simulating a sensible heat flux larger than heat storage, as observed. A sensitivity comparison using generic dense city parameters, derived from the Coordination of Information on the Environment (CORINE) land cover database, and those from a surface database developed specifically for the Marseille city center shows the importance of correctly documenting the urban surface. Overall, the TEB scheme is shown to be fairly robust, consistent with results from previous studies.

    Synthetic chemists have provided a wide array of supramolecular assemblies able to encapsulate guest molecules. The scope of this tutorial review focuses on supramolecular host molecules capable of reversibly encapsulating polyatomic guests. Much work has been done to determine the mechanism of guest encapsulation and guest release. This review covers common methods of monitoring and characterizing guest exchange such as NMR, UV-VIS, mass spectroscopy, electrochemistry, and calorimetry and also presents representative examples of guest exchange mechanisms. The guest exchange mechanisms of hemicarcerands, cucurbiturils, hydrogen-bonded assemblies, and metal-ligand assemblies are discussed. Special attention is given to systems which exhibit constrictive binding, a motif common in supramolecular guest exchange systems.

    Leishmaniasis is considered a rural disease in Europe. However, circumstantial evidence has indicated urban transmission of leishmaniasis and phleboviruses in the urban area of Marseille, France. To investigate this urban transmission, sandflies were trapped in 33 locations in the urban area (horse farms, public gardens and a residential area). Sandflies were always captured: 87.8% were Phlebotomus perniciosus, a vector of Leishmania infantum and Toscana and Massilia viruses. RT-PCR and cell culture inoculation identified the Massilia virus in 2/99 pools of sandflies, and PCR identified Leishmania in 5/99. No dual infection was observed, but both pathogens were detected in samples from the same trapping site. © 2013 The Authors Clinical Microbiology and Infection © 2013 European Society of Clinical Microbiology and Infectious Diseases.

En 1991, 1992 et 1994, des séries de plongées furent organisées par le Ministère de la Culture, avec la participation de JEAN COURTIN, préhistorien et plongeur. D’autres recherches furent reprises dernièrement, en 2002 et 2003, par les cosignataires de l’article.La localisation extraordinaire de l’entrée de cette caverne est due à la montée du niveau de la mer après la fin de la dernière glaciation.

L’art découvert se trouve dans des salles supérieures restées hors d’eau. Environ 177 figures d’animaux ont été répertoriées, ainsi que 216 signes géométriques de formes diverses, 65 mains négatives, et l’image d’un homme tué. Les sols sont jonchés de charbons, restes de torches ou de feux allumés pour obtenir le charbon nécessaire aux dessins. Les gens n’habitaient pas dans ces lieux retirés. Ils les utilisèrent pour leurs cérémonies mais également pour obtenir le mondmilch raclé sur les parois et des fragments de concrétions, qui servirent probablement comme « médecines ».Les 27 dates obtenues par la méthode du radiocarbone ont montré que la caverne avait été fréquentée pendant deux périodes principales, d’abord aux alentours de 26 à 27.000 ans avant le présent, puis il y a 19.000 ans environ.La grotte Cosquer, dont plus des trois-quarts de l’art furent sans doute détruits par son ennoiement, est une découverte majeure, par sa localisation en Provence, par les activités dont elle fut le théâtre, et par l’abondance du bestiaire, des mains et des

    The person celebrating CERN's 25th anniversary whose photograph we published last week was not just any guest. Readers have pointed out that it was Wim Klein, whose remarkable abilities are part of CERN's history. Well known as one of the best "human calculators", Wim was recruited by CERN in 1957 to verify computer programs, which at the time were still stumbling. Moreover, he regularly beat their speed in calculating and gave breath-taking demonstrations. During one such demonstration in September 1973, he calculated the 19th root of a 133-digit number in less than 2 minutes !

    The Astrobee Research Facility will maintain three identical free-flying Astrobee robots on the ISS. After the Astrobees are launched and commissioned in 2018, they will replace the SPHERES robots that have been operating on the ISS since 2006 (Fig. 2). Over the years, the SPHERES have been among the most-used payloads on the ISS, supporting dozens of experiments from a variety of guest scientists. In the next section, we'll talk about past SPHERES experiments as possible inspiration for your future research on Astrobee. Compared to SPHERES, the Astrobee robots will offer many new capabilities and will require less astronaut time to support, so we hope the new facility will be able to fly experiments much more often.

    The UBL/CLU (urban boundary layer/couche limite urbaine) observation and modelling campaign is a side-project of the regional photochemistry campaign ESCOMPTE. UBL/CLU focuses on the dynamics and thermodynamics of the urban boundary layer of Marseille, on the Mediterranean coast of France. The objective of UBL/CLU is to document the four-dimensional structure of the urban boundary layer and its relation to the heat and moisture exchanges between the urban canopy and the atmosphere during periods of low wind conditions, from June 4 to July 16, 2001. The project took advantage of the comprehensive observational set-up of the ESCOMPTE campaign over the Berre-Marseille area, especially the ground-based remote sensing, airborne measurements, and the intensive documentation of the regional meteorology. Additional instrumentation was installed as part of UBL/CLU. Analysis objectives focus on (i) validation of several energy balance computational schemes such as LUMPS, TEB and SM2-U, (ii) ground truth and urban canopy signatures suitable for the estimation of urban albedos and aerodynamic surface temperatures from satellite data, (iii) high resolution mapping of urban land cover, land-use and aerodynamic parameters used in UBL models, and (iv) testing the ability of high resolution atmospheric models to simulate the structure of the UBL during land and sea breezes, and the related transport and diffusion of pollutants over different districts of the city. This paper presents initial results from such analyses and details of the overall experimental set-up.

    3D numerical simulations with the Meso-NH atmospheric model including the Town Energy Balance urban parameterization, are conducted over the south-east of France and the one million inhabitants city of Marseille in the frameworks of the ESCOMPTE-UBL program. The geographic situation of the area is relatively complex, because of the proximity of the Mediterranean Sea and the presence of numerous massifs, inducing complex meteorological flows. The present work is focused on six days of the campaign, characterized by the development of strong summer sea-breeze circulations. A complete evaluation of the model is initially realized at both regional- and city-scales, by using the large available database. The regional evaluation shows a good behavior of the model, during the six days of simulation, either for the parameters near the surface or for the vertical profiles describing the structure of the atmosphere. The urban-scale evaluation indicates that the fine structure of the horizontal fields of air temperature above the city is correctly simulated by the model. A specific attention is then pointed to the 250-m horizontal resolution outputs, focused on the Marseille area, for two days of the campaign. From the study of the vertical structure of the Urban Boundary Layer and the thermodynamic fields near the surface, one underscores the important differences due to the regional and local flows, and the complex interactions that occur between the urban effects and the effects of sea breezes.

  3. Guest loyalty in hospitality industry

    2015-01-01

    Full Text Available The continuous growth of competition in the hospitality sector has created the need to retain guests and prevent them from switching company due to better offer or saturation. Loyal customers are a valuable asset for catering companies, not only because of the awareness of the effects of customer loyalty. They tend to spread word-of-mouth advertising, more tolerant to price changes, as well as they casually create a linkage to their friends, relatives, colleagues, and other probable consumers and thus enable businesses to uphold a guest's base. By recognizing loyalty guests' importance, the global hospitality industry created monetary and non-monetary rewards for loyal visitors, delayed gratification (points collection and immediate rewards, as well as numerous other reward systems that try to keep them. To win customer loyalty, together with all benefits arising from it, caterers need to become familiar with factors, which determine guests' loyalty. The paper will show the results of research regarding the impact of the service quality and guests' satisfaction to their loyalty. Many authors have confirmed that employees' satisfaction affected customers' satisfaction, so this paper will give an answer does it influence on customers' loyalty as well.

    We investigated the seasonal trends of OA sources affecting the air quality of Marseille (France), which is the largest harbor of the Mediterranean Sea. This was achieved by measurements of nebulized filter extracts using an aerosol mass spectrometer (offline-AMS). In total 216 PM2. 5 (particulate matter with an aerodynamic diameter water-soluble ions, metals, elemental and organic carbon (EC / OC), and organic markers, including n-alkanes, hopanes, polycyclic aromatic hydrocarbons (PAHs), lignin and cellulose pyrolysis products, and nitrocatechols. The application of positive matrix factorization (PMF) to the water-soluble AMS spectra enabled the extraction of five factors, related to hydrocarbon-like OA (HOA), cooking OA (COA), biomass burning OA (BBOA), oxygenated OA (OOA), and an industry-related OA (INDOA). Seasonal trends and relative contributions of OA sources were compared with the source apportionment of OA spectra collected from the AMS field deployment at the same station but in different years and for shorter monitoring periods (February 2011 and July 2008). Online- and offline-AMS source apportionment revealed comparable seasonal contribution of the different OA sources. Results revealed that BBOA was the dominant source during winter, representing on average 48 % of the OA, while during summer the main OA component was OOA (63 % of OA mass on average). HOA related to traffic emissions contributed on a yearly average 17 % to the OA mass, while COA was a minor source contributing 4 %. The contribution of INDOA was enhanced during winter (17 % during winter and 11 % during summer), consistent with an increased contribution from light alkanes, light PAHs (fluoranthene, pyrene, phenanthrene), and selenium, which is commonly considered as a unique coal combustion and coke production marker. Online- and offline-AMS source apportionments revealed evolving levoglucosan : BBOA ratios, which were higher during late autumn and March. A similar seasonality was

The special issue opens with an article by P. Clint Rogers, Stephen W. Liddle, Peter Chan, Aaron Doxey and Brady Isom (all from the USA argue that the emergence of Web 2.0 technologies, and the possibilities and the realities they represent, are fuelling profound changes to theoretical views of learning and teaching. According to the authors, in contrast to earlier e-learning efforts that simply replicated traditional models of learning and teaching in online environments, ‘E-Learning 2.0’ offers opportunities to move away from the highly centralised industrial model of learning of the past era, towards achieving individual empowerment within a global learning community. They also argue that as the personal, social and flexible technologies of Web 2.0 proliferate, the importance of re-usability and interoperability will also increase; correspondingly there is also a need for standardisation efforts to support the attainment of these goals. The second article, focuses on the use of specific Web 2.0 technologies written by Abdullah Kuzu (Anadolu University, Turkey looks at pre-service teachers’ perceptions of the use of blogs for instruction and

  7. Foreign Guests in Ancient Greece

    Full Text Available Xenía was a special relationship between a foreign guest and his host in Ancient Greece. The ritual of hosting a foreigner included an exchange of objects, feasting, and the establishment of friendship between people from different social backgrounds. This relationship implied trust, loyalty, friendship, and mutual aid between the people involved. Goods and services were also exchanged without any form of payment. There were no formal laws governing xenía – it was based entirely on a moral appeal. Mutual appreciation between the host and the guest was established during the ritual, but the host did retain a certain level of superiority over the guest. Xenía was one of the most important institutions in Ancient Greece. It had a lot of features and obligations similar to kinship and marriage. In literary sources the word xénos varies in meaning from “enemy stranger”, “friendly stranger”, “foreigner”, “guest”, “host” to “ritual friend”, and it is often hard to tell which usage is appropriate in a given passage. The paper describes the emphasis on hospitality towards foreigners. It presents an example of a depiction indicating xenía is presented, as well as several objects which were traded during the ritual. The paper also addresses the importance of hospitality in Greek drama in general, especially with examples of violations of the hospitality code.

    Full Text Available We investigated the seasonal trends of OA sources affecting the air quality of Marseille (France, which is the largest harbor of the Mediterranean Sea. This was achieved by measurements of nebulized filter extracts using an aerosol mass spectrometer (offline-AMS. In total 216 PM2. 5 (particulate matter with an aerodynamic diameter  <  2.5 µm filter samples were collected over 1 year from August 2011 to July 2012. These filters were used to create 54 composite samples which were analyzed by offline-AMS. The same samples were also analyzed for major water-soluble ions, metals, elemental and organic carbon (EC ∕ OC, and organic markers, including n-alkanes, hopanes, polycyclic aromatic hydrocarbons (PAHs, lignin and cellulose pyrolysis products, and nitrocatechols. The application of positive matrix factorization (PMF to the water-soluble AMS spectra enabled the extraction of five factors, related to hydrocarbon-like OA (HOA, cooking OA (COA, biomass burning OA (BBOA, oxygenated OA (OOA, and an industry-related OA (INDOA. Seasonal trends and relative contributions of OA sources were compared with the source apportionment of OA spectra collected from the AMS field deployment at the same station but in different years and for shorter monitoring periods (February 2011 and July 2008. Online- and offline-AMS source apportionment revealed comparable seasonal contribution of the different OA sources. Results revealed that BBOA was the dominant source during winter, representing on average 48 % of the OA, while during summer the main OA component was OOA (63 % of OA mass on average. HOA related to traffic emissions contributed on a yearly average 17 % to the OA mass, while COA was a minor source contributing 4 %. The contribution of INDOA was enhanced during winter (17 % during winter and 11 % during summer, consistent with an increased contribution from light alkanes, light PAHs (fluoranthene, pyrene, phenanthrene, and

    On July 14, 2015, after 9.5 years of cruise, NASA's New Horizons spacecraft flew past the Pluto system to gather first images humankind had ever seen on Pluto and its five moons. While much has been discovered about the Pluto system since New Horizons launch in 2006, the system has never been imaged at high resolution and anticipation of the "First Light" of the Pluto system had been anticipated by planetary enthusiasts for decades. The Johns Hopkins Applied Physics Laboratory (APL), which built and operates New Horizons, was the focal point for gathering three distinct groups: science and engineering team members; media and public affairs representatives; and invited public, including VIP's. Guest operations activities were focused on providing information primarily to the invited public and VIP's. High level objectives for the Guest Operations team was set to entertain and inform the general public, offer media reaction shots, and to deconflict activities for the guests from media activities wherever possible. Over 2000 people arrived at APL in the days surrounding closest approach for guest, science or media operations tracks. Reaction and coverage of the Guest Operations events was universally positive and global in impact: iconic pictures of the auditorium waving flags during the moment of closest approach were published in media outlets on every continent. Media relations activities ensured coverage in all key media publications targeted for release, such as the New York Times, Science, Le Monde, and Nature. Social and traditional media coverage of the events spanned the globe. Guest operations activities are designed to ensure that a guest has a memorable experience and leaves with a lifelong memory of the mission and their partnership in the activity. Results, lessons learned, and other data from the New Horizons guest operations activity will be presented and analyzed.

    ESCOMPTE programme aims at studying the emissions of primary pollutants in industrial and urban areas, their transport, diffusion and transformation in the atmosphere. This experiment, carried out in southeast France, can be used to validate and to improve meteorological and chemical mesoscale models. One major goal of this experiment was to follow the pollutant plumes, and to investigate its thermodynamic and physico-chemical time evolution. This was realized by means of constant volume balloons, located by global position satellite (GPS) and equipped with thermodynamic and ozone sensors, flying at constant density levels. During the two ESCOMPTE campaigns that took place in June and July 2000 and 2001, 40 balloons were launched, 17 of them equipped with ozone sensors during the day from 0800 to 1800 UTC. Balloons' altitudes flight levels ranged between 400 and 1200 m altitude with Mistral (northerly synoptic flow) and Sea Breeze (southerly breeze) conditions. The atmospheric boundary layer (ABL) topography of the experimental domain is complex and varies strongly from day to day. Its depth presents a large gradient from the sea coast to the north part of the ESCOMPTE domain, and also more complex variability within the domain. The balloons' trajectories describe the evolution of the pollutant plume emitted from the industrial area of Fos-Berre or from the Marseille urban area. Constant volume balloons give a good description of the trajectories of these two plumes. The balloons, which fly at an isopicnic level, cross different atmospheric layers chiefly depending on the ABL height in relation with the constant volume balloons flight level. Thus, each balloon flight is decomposed into different segments that correspond to the same atmospheric layer. In each segment, the ozone content variation is analyzed in relation to other thermodynamical parameters measured by the balloon and mainly to the vapor mixing ratio content. During ESCOMPTE campaign, the mean linear

    Extravehicular activity (EVA) of astronauts during space missions is simulated nowadays underwater in neutral buoyancy facilities. Certain aspects of weightlessness can be reproduced underwater by adding buoyancy to a diver-astronaut, therefore exposing the subject to the difficulties of working without gravity. Such tests were done at the COMEX' test pool in Marseilles in the 1980s to train for a French-Russian mission to the MIR station, for the development of the European HERMES shuttle and the COLUMBUS laboratory. However, space agencies are currently studying missions to other destinations than the International Space Station in orbit, such as the return to the Moon, NEO (near-Earth objects) or Mars. All these objects expose different gravities: Moon has one sixth of Earth's gravity, Mars has a third of Earth's gravity and asteroids have virtually no surface gravity; the astronaut "floats" above the ground. The preparation of such missions calls for a new concept in neutral buoyancy training, not on man-made structures, but on natural terrain, underwater, to simulate EVA operations such as sampling, locomotion or even anchoring in low gravity. Underwater sites can be used not only to simulate the reduced gravity that astronauts will experience during their field trips, also human factors like stress are more realistically reproduced in such environment. The Bay of Marseille hosts several underwater sites that can be used to simulate various geologic morphologies, such as sink-holes which can be used to simulate astronaut descends into craters, caves where explorations of lava tubes can be trained or monolithic rock structures that can be used to test anchoring devices (e.g., near Earth objects). Marseilles with its aerospace and maritime/offshore heritage hosts the necessary logistics and expertise that is needed to perform such simulations underwater in a safe manner (training of astronaut-divers in local test pools, research vessels, subsea robots and

  6. Impact of the Rhône and Durance valleys on sea-breeze circulation in the Marseille area

    2005-03-01

    Sea-breeze dynamics in the Marseille area, in the south of France, is investigated in the framework of the ESCOMPTE experiment conducted during summer 2001 in order to evaluate the role of thermal circulations on pollutant transport and ventilation. Under particular attention in this paper is the sea-breeze channelling by the broad Rhône valley and the narrow Durance valley, both oriented nearly-north-south, i.e., perpendicular to the coastline, and its possible impact on the sea-breeze penetration, intensity and depth, which are key information for air pollution issues. One situation of slight synoptic pressure gradient leading to a northerly flow in the Rhône valley (25 June 2001) and one situation of a weak onshore prevailing synoptic wind (26 June 2001) are compared. The impact of the Rhône and Durance valleys on the sea-breeze dynamics on these two typical days is generalized to the whole ESCOMPTE observing period. The present study shows by combining simple scaling analysis with wind data from meteorological surface stations and Doppler lidars that (i) the Durance valley always affects the sea breeze by accelerating the flow. A consequence is that the Durance valley contributes to weaken the temperature gradient along the valley and thus the sea-breeze circulation. In some cases, the acceleration of the channelled flow in the Durance valley suppresses the sea-breeze flow by temperature gradient inhibition; (ii) the Rhône valley does not generally affect the sea breeze significantly. However, if the sea breeze is combined with an onshore flow, it leads to further penetration inland and intensification of the low-level southerly flow. In this situation, lateral constriction may accelerate the sea breeze. Simple scaling analysis suggests that Saint Paul (44.35°N, about 100 km from the coastline) is the lower limit where sea breeze can be affected by the Rhône valley. These conclusions have implications in air quality topics as channelled sea breeze may

    CONSPECTUS: For device miniaturization, nanotechnology follows either the "top-down" approach scaling down existing larger-scale devices or the "bottom-up' approach assembling the smallest possible building blocks to functional nanoscale entities. For synthetic nanodevices, self-assembly on surfaces is a superb method to achieve useful functions and enable their interactions with the surrounding world. Consequently, adaptability and responsiveness to external stimuli are other prerequisites for their successful operation. Mechanically interlocked molecules such as rotaxanes and catenanes, and their precursors, that is, molecular switches and supramolecular switches including pseudorotaxanes, are molecular machines or prototypes of machines capable of mechanical motion induced by chemical signals, biological inputs, light or redox processes as the external stimuli. Switching of these functional host-guest systems on surfaces becomes a fundamental requirement for artificial molecular machines to work, mimicking the molecular machines in nature, such as proteins and their assemblies operating at dynamic interfaces such as the surfaces of cell membranes. Current research endeavors in material science and technology are focused on developing either a new class of materials or materials with novel/multiple functionalities by shifting host-guest chemistry from solution phase to surfaces. In this Account, we present our most recent attempts of building monolayers of rotaxanes/pseudorotaxanes on surfaces, providing stimuli-induced macroscopic effects and further understanding on the switchable host-guest systems at interfaces. Biocompatible versions of molecular machines based on synthetic macrocycles, such as cucurbiturils, pillararenes, calixarenes, and cyclodextrins, have been employed to form self-assembled monolayers of gates on the surfaces of mesoporous silica nanoparticles to regulate the controlled release of cargo/drug molecules under a range of external stimuli

    The wasp Polistes dominulus (PD), the yellow jacket Vespula germanica (VG) and the hornet Vespa crabro (VC) are allergenically important social wasps found in Europe. Serum samples obtained from allergic subjects in Marseille were studied in order to determine the positivity by RAST to these venoms. All the sera studied had IgE antibodies to at least one of the wasp venoms tested and 50% had IgE antibodies that reacted with more than one venom. The presence in some sera of IgE antibodies to the venoms of all three wasps and RAST inhibition studies suggested that the three venoms were relevant in the area studied and that most sera were positive to the three venoms due to allergenic cross-reactivity. However, inhibition studies revealed that 2 patients may have had antibodies that did not cross-react and that were specific for the venom of only one species.

    A retrospective case review study of viper envenomations collected by the Marseille's Poison Centre between 1996 and 2008 was performed. 174 cases were studied (52 grade 1 = G1, 90 G2 and 32 G3). G1 patients received symptomatic treatments (average hospital stay 0.96 day). One hundred and six (106) of the G2/G3 patients were treated with the antivenom Viperfav* (2.1+/-0.9 days in hospital), while 15 of them received symptomatic treatments only (plus one immediate death) (8.1+/-4 days in hospital, 2 of them died). The hospital stay was significantly reduced in the antivenom treated group (p < 0.001), and none of the 106 antivenom treated patients had immediate (anaphylaxis) or delayed (serum sickness) allergic reactions. Viperfav* antivenom was safe and effective for treating asp viper venom-induced toxicity.

    Polycyclic aromatic hydrocarbons (PAHs) were analysed from sewage treatment plant waters and surface waters collected in continental (rivers), harbour and off-shore marine sites from Marseilles Bay and Vermeille coastal areas between 2009 and 2013 (Northwestern Mediterranean Sea, France). After collection, water samples were first filtered on glass fiber filters, then PAHs from the dissolved phase were extracted using liquid-liquid or solid phase extraction (SPE) methods, while those from particles were treated according to Bligh and Dyer method. After a possible purification step, extracts were analysed by gas chromatography coupled to mass spectrometry (GC-MS). Regardless of the study area, dissolved and particulate PAH (18 parents + alkylated homologues) concentration averages were 150.2 ± 140.5 ng l-1and 39.4 ± 71.2 ng l-1, respectively. Interestingly, the concentration in dissolved PAHs was on average 3.8 higher than the concentration in particulate PAHs. In addition, a gradient of PAH concentrations was observed from coastal waters with the highest values in harbours and outlet sewage effluents and the lowest values in off-shore marine waters. Intermediate concentrations were recorded in continental waters. In the Marseilles Bay, dissolved PAH concentrations were significantly higher and associated to increased signatures of unburned and combusted fossil fuels, mainly from heating, during the cold period (November-April). In contrast, unburned petroleum signature dominated in the warm period (May-October), emphasizing the intense shipping traffic and urban/industrial activities occurring in one of the largest Mediterranean harbour and city. Conversely, in the Vermeille coastal waters, dissolved PAH concentrations were higher during the warm period when particulate PAHs displayed the lowest concentrations, suggesting a seasonal related partition between dissolved and particulate PAHs. In addition, in the Vermeille coastal waters, PAHs were dominated by

    Marseille, the most important port of the Mediterranean Sea, represents a challenging case study for source apportionment exercises, combining an active photochemistry and multiple emission sources, including fugitive emissions from industrial sources and shipping. This paper presents a Chemical Mass Balance (CMB) approach based on organic markers and metals to apportion the primary sources of organic aerosol in Marseille, with a special focus on industrial emissions. Overall, the CMB model accounts for the major primary anthropogenic sources including motor vehicles, biomass burning and the aggregate emissions from three industrial processes (heavy fuel oil combustion/shipping, coke production and steel manufacturing) as well as some primary biogenic emissions. This source apportionment exercise is well corroborated by 14C measurements. Primary OC estimated by the CMB accounts on average for 22% of total OC and is dominated by the vehicular emissions that contribute on average for 17% of OC mass concentration (vehicular PM contributes for 17% of PM2.5). Even though industrial emissions contribute only 2.3% of the total OC (7% of PM2.5), they are associated with ultrafine particles (Dpheavy metals such as Pb, Ni and V. On one hand, given that industrial emissions governed key primary markers, their omission would lead to substantial uncertainties in the CMB analysis performed in areas heavily impacted by such sources, hindering accurate estimation of non-industrial primary sources and secondary sources. On the other hand, being associated with bursts of submicron particles and carcinogenic and mutagenic components such as PAH, these emissions are most likely related with acute ill-health outcomes and should be regulated despite their small contributions to OC. Another important result is the fact that 78% of OC mass cannot be attributed to the major primary sources and, thus, remains un-apportioned. We have consequently critically investigated the uncertainties

  17. Science in the schoolhouse: an uninvited guest.

    2004-01-01

    Science and scientific thinking have not made a substantial impact on educational practice. In this discussion, we examine the relationship between science and education and delineate four reasons for characterizing science as an uninvited guest in schools: (a) Science is not highly regarded in society; (b) good science and bad science are often mistaken for one another; (c) the amount of current data is overwhelming; and (d) science is not easy for those who practice it (researchers), those who translate it (teacher educators), or those who consume it (teachers). We suggest several strategies to improve this relationship, including promoting standards of educational practice, emphasizing the role of teacher educators as translators of the research base into classroom practice, and linking student outcomes with the use of effective instructional practices.

    2015-03-01

    Jatropha curcas L. is an inedible plant belonging to the Euphorbiaceae family that is growing in subtropical zones of all continents. We report a series of 24 cases of poisoning with J. curcas seeds or fruits reported to poison centers in Paris and Marseille between December 2000 and June 2014. Fifteen adults and 9 children ingested J. curcas seeds or fruits. All patients experienced gastrointestinal disorders, within the first hours following ingestion: nausea, vomiting, diarrhea and abdominal pain. Laboratory investigations performed in 10 patients revealed minor abnormalities: CK elevation (8 cases), dehydration (5 cases) with moderate elevation of serum creatinine levels (3 cases), and mildly increased serum bilirubin (8 cases). Complete remission of all clinical signs was observed within 48 hours in the 20 cases for which the outcome was known. Previously published cases of J. curcas poisoning were very similar to ours: As in our series, gastrointestinal disorders were always present. They were sometimes associated with neurological or cardiovascular signs, and hepatic or renal disorders; these were generally interpreted as complications of severe gastroenteritis, although direct toxic effects could not be formally excluded. In most cases, simple supportive measures were sufficient to ensure complete recovery within 24-48 hours. J Curcas poisoning incidence is certainly increasing because the plant is cultivated to produce biodiesel and is now largely present in most subtropical countries. As a consequence, local health professionals should be informed of the toxic properties of this plant.

  19. The Marseille Observatory 1860-1920: missed opportunities and elebrated achievements

    Caplan, James

    2001-10-01

    After summarizing the early history of the Marseille Observatory (founded by the Jesuits and operational in 1702), I describe the circumstances leading to the takeover by Le Verrier in the 1860s. The observatory was rebuilt on the Plateau Longchamp and new instruments were installed, most notably the 80-cm Foucault glass-mirror telescope. The work of the new observatory is then presented, and the instruments described, starting with the Le Verrier period and continuing through the long directorship of Stephan, and then Bourget. The overall success of the observatory in its Longchamp site was due in part to the assiduous pursuit of routine observations and to the discovery of comets and asteroids, combined with the `exploratory' observations of `nebulae' by Stephan. In addition, the first stellar interferometry observations, and the first applications of the Fabry-Perot interferometer to nebular observations, were important achievements. On the other hand, the failure in the beginning of the twentieth century to adapt the telescopes to photography condemned the observatory to a long period of missed opportunities, from which it did not recover for several decades.

  20. A View From The Sea The Regeneration of Marseille Waterfront: Iconic Buildings And Mediterranean Sea

    Directory of Open Access Journals (Sweden)

    Maria Elena Buslacchi

    2014-01-01

    Full Text Available In this paper I will discuss how the isomorphic trend of urban regeneration of waterfronts implies a modeling which is not free from critical points. If we focus on the growing use of art and culture as a tool, both in stable museum form both in ephemeral festival form, we must pair this tool with a local contextualization which requires a deep and multi-prospectic knowledge of the territory. In this context a view “from the sea” becomes fundamental when we think to renovate the identity of the port cities materially and, at the same time, symbolically. First a general introduction about the actual evolution of strategies for regeneration of coastal areas will be given. Then two fundamental specific case-studies in the regeneration of the city of Marseille  will be discussed: Vieux Port and the Esplanade - Fort St-Jean. These areas, studied during my Ph. D. thesis, are meaningful for the connection generated between the local reality and the original project, based on a general purpose model. This paper will try to employ ethnographic methodology to examine which functions have been associated to renewed areas and how these acquired functions can be connected with project steps and with already observed results in other cities. A descriptive approach is predominant in this work; anyway a critical judgment cannot be avoided. This sort of judgment is not to be extended to all the other effects which cannot be directly observed within the case-study.

  1. The guest-worker in Western Europe--an obituary.

    Science.gov (United States)

    Castles, S

    1986-01-01

    The significance of guest workers is examined for six Western European countries. It is found that "the dynamics of the migratory process led to family reunification and settlement, against the original intentions of the workers, employers and states concerned. The recruitment of guest-workers stopped after 1974, but many migrants stayed on, becoming permanent ethnic minorities, in a situation of economic and social crisis. It is argued that guest-worker systems inevitably lead to permanent migration in the long run, and that it is better to plan for orderly settlement through appropriate policies." excerpt

  3. A Different Guest Worker Story: Roma Guest Workers – a Transnational Minority in Transmigration

    Directory of Open Access Journals (Sweden)

    Ana Banić-Grubišić

    2016-03-01

    Full Text Available he paper considers the ambiguity of the term ‘guest worker’, based on the example of economic migrants who belong to the Roma population. Over the last fifty years, members of the Roma minority have migrated to Western European countries for different reasons (economic, political and social reasons, and there is no official data on the precise number of Roma who have migrated abroad, whether permanently or temporarily. It is possible to establish a number of categories of Roma immigrants who reside permanently or temporarily in Western European countries. These are: the so-called “classic guest workers” who, through legal or illegal means went to work abroad in the 60’s and 70’s, and mostly settled permanently in the host countries; Roma refugees from Kosovo and/or asylum seekers who left the country during the wars in the 90’s, and who were returned to Serbia after the signing of the Readmission treaty; and those Roma who represent occasional economic migrants: people who, after Serbia was put on the white Schengen list (the liberalization of the visa policy for citizens of Serbia, spend three months at a time working abroad. Even though these three categories of Roma workers have different reasons for migrating from and returning to Serbia, the majority of the population perceives them as a unified, distinct whole – as guest workers. The paper is the result of fieldwork conducted in South-Eastern Serbia, in the village of Minicevo.

    Dölle, Sarah; Park, Ji Hyun; Schymura, Stefan; Jo, Hyeran; Scalia, Giusy; Lagerwall, Jan P. F.

    In this chapter we discuss the benefits, peculiarities and main challenges related to nanoparticle templating in lyotropic liquid crystals. We first give a brief bird's-eye view of the field, discussing different nanoparticles as well as different lyotropic hosts that have been explored, but then quickly focus on the dispersion of carbon nanotubes in surfactant-based lyotropic nematic phases. We discuss in some detail how the transfer of orientational order from liquid crystal host to nanoparticle guest can be verified and which degree of ordering can be expected, as well as the importance of choosing the right surfactant and its concentration for the stability of the nanoparticle suspension. We introduce a method for dispersing nanoparticles with an absolute minimum of stabilizing surfactant, based on dispersion below the Krafft temperature, and we discuss the peculiar phenomenon of filament formation in lyotropic nematic phases with a sufficient concentration of well-dispersed carbon nanotubes. Finally, we describe how the total surfactant concentration in micellar nematics can be greatly reduced by combining cat- and anionic surfactants, and we discuss how nanotubes can help in inducing the liquid crystal phase close to the isotropic-nematic boundary.

  5. Mechanism of host-guest complexation by cucurbituril.

    Márquez, César; Hudgins, Robert R; Nau, Werner M

    2004-05-12

    The factors affecting host-guest complexation between the molecular container compound cucurbit[6]uril (CB6) and various guests in aqueous solution are studied, and a detailed complexation mechanism in the presence of cations is derived. The formation of the supramolecular complex is studied in detail for cyclohexylmethylammonium ion as guest. The kinetics and thermodynamics of complexation is monitored by NMR as a function of temperature, salt concentration, and cation size. The binding constants and the ingression rate constants decrease with increasing salt concentration and cation-binding constant, in agreement with a competitive binding of the ammonium site of the guest and the metal cation with the ureido carbonyl portals of CB6. Studies as a function of guest size indicate that the effective container volume of the CB6 cavity is approximately 105 A(3). It is suggested that larger guests are excluded for two reasons: a high activation barrier for ingression imposed by the tight CB6 portals and a destabilization of the complex due to steric repulsion inside. For example, in the case of the nearly spherical azoalkane homologues 2,3-diazabicyclo[2.2.1]hept-2-ene (DBH, volume ca. 96 A(3)) and 2,3-diazabicyclo[2.2.2]oct-2-ene (DBO, volume ca. 110 A(3)), the former forms the CB6 complex promptly with a sizable binding constant (1300 M(-1)), while the latter does not form a complex even after several months at optimized complexation conditions. Molecular mechanics calculations are performed for several CB6/guest complexes. A qualitative agreement is found between experimental and calculated activation energies for ingression as a function of both guest size and state of protonation. The potential role of constrictive binding by CB6 is discussed.

    Full Text Available  This issue of Seminar.net contains three articles that were written in connection with a Norwegian e-learning conference titled “Networked collaboration, sharing and response”. The conference was held in Mars 2008 in Trondheim, and the presentations from the conference is available (in norwegian language at http://www.nvu.no. Networked collaboration was chosen as a theme because collaboration is important to achieve learning, according to the social-constructivistic pedagogy that has a strong standing in Norway, but how should this occur on the net? Sharing of content, as in digital learning resources, is a phenomenon with increasing popularity as described in the OECD-report “Giving Knowledge for Free”. But to achieve reuse of content, not only publishing it, it is important with a networked community where the plethora of information can be sorted with relevance to specific topics. Response is about guiding, coaching and tutoring. In what ways may resources and tools be used to move in the direction of solving Bloom’s two sigma problem/challenge? The first article, by Morten Flate Paulsen, shows how cooperative learning can be implemented successfully so that students have optimal individual freedom within online learning communities. The second article, by Carl F. Dons, shows how student teachers can be prepared to deal with pupils who have a wide range of experiences of the digital world. The third and last article, by Kristin Dale, is sharing experiences with multiple choice-tests to give midterm responses to students. In addition, this issue has a commentary article by Rune Krumsvik discussing the need to develop new practices for teachers and students on the background of the digital developments. The conference and articles covers three big themes. It may be difficult to find more important issues, apart from finding money and time to support its development. Olav Skundberg, guest editorAssociate professor

  12. Total Quality Management Implementation and Guest Satisfaction in Hospitality

    Directory of Open Access Journals (Sweden)

    2017-02-01

    Full Text Available Total quality management (TQM has become a modern system of constant improvement of the quality of all company activities. The purpose of this study is to measure the expectations and satisfaction of the guests concerning the attribute quality of the hotel product. Furthermore obtained results were compared in such a way as to analyse particularly the reviews of hotels which have implemented TQM and have the ISO 9001 certificates with reviews from hotels which have not implemented TQM and do not have the ISO 9001 certificates. The conducted analysis included 55 hotels in Serbia belonging to the 4- and 5-star categories, i.e. 1308 guests who have stayed in them. The results show that between the observed groups of guests there are fewer differences in expectations than in perception, and that generally speaking guests who have stayed in the hotels that have implemented TQM are more satisfied. The biggest difference concerning the guest satisfaction with the quality of service in the observed hotels is noticeable in relation to the employees and the value-for-money.

    While it has long been known that some highly adsorbing microporous materials suddenly become inaccessible to guest molecules below certain temperatures, previous attempts to explain this phenomenon have failed. Here we show that this anomalous sorption behaviour is a temperature-regulated guest admission process, where the pore-keeping group's thermal fluctuations are influenced by interactions with guest molecules. A physical model is presented to explain the atomic-level chemistry and structure of these thermally regulated micropores, which is crucial to systematic engineering of new functional materials such as tunable molecular sieves, gated membranes and controlled-release nanocontainers. The model was validated experimentally with H2, N2, Ar and CH4 on three classes of microporous materials: trapdoor zeolites, supramolecular host calixarenes and metal-organic frameworks. We demonstrate how temperature can be exploited to achieve appreciable hydrogen and methane storage in such materials without sustained pressure. These findings also open new avenues for gas sensing and isotope separation.

    Full Text Available Hotel companies which operate in today's competitive environment must constantly work on improving their products and services, at the request of their guests. Customer satisfaction is the key to retaining existing and attracting new guests. To achieve this goal, managers in the hotel organizations have become aware of the fact that the quality of staying in hotel represent unique experience for tourists. Lot of papers are dealing with the exploration of this topic, it only proves its importance nowadays. However, insufficient attention is paid to the simultaneous study of experience of guests and their satisfaction through the offered models (indexes that are created for this purpose. The purpose of this paper is to show the importance of these issues and identify their potential symbiosis.

    Tang, Du; Barnett, J Wesley; Gibb, Bruce C; Ashbaugh, Henry S

    2017-11-30

    Octa-acid (OA) and tetra-endo-methyl octa-acid (TEMOA) are water-soluble, deep-cavity cavitands with nanometer-sized nonpolar pockets that readily bind complementary guests, such as n-alkanes. Experimentally, OA exhibits a progression of 1:1 to 2:2 to 2:1 host/guest complexes (X:Y where X is the number of hosts and Y is the number of guests) with increasing alkane chain length from methane to tetradecane. Differing from OA only by the addition of four methyl groups ringing the portal of the pocket, TEMOA exhibits a nonmonotonic progression of assembly states from 1:1 to 2:2 to 1:1 to 2:1 with increasing guest length. Here we present a systematic molecular simulation study to parse the molecular and thermodynamic determinants that distinguish the succession of assembly stoichiometries observed for these similar hosts. Potentials of mean force between hosts and guests, determined via umbrella sampling, are used to characterize association free energies. These free energies are subsequently used in a reaction network model to predict the equilibrium distributions of assemblies. Our models accurately reproduce the experimentally observed trends, showing that TEMOA's endo-methyl units constrict the opening of the binding pocket, limiting the conformations available to bound guests and disrupting the balance between monomeric complexes and dimeric capsules. The success of our simulations demonstrate their utility at interpreting the impact of even simple chemical modifications on supramolecular assembly and highlight their potential to aid bottom-up design.

    Langton, Matthew J; Beer, Paul D

    2014-07-15

    CONSPECTUS: The promise of mechanically interlocked architectures, such as rotaxanes and catenanes, as prototypical molecular switches and shuttles for nanotechnological applications, has stimulated an ever increasing interest in their synthesis and function. The elaborate host cavities of interlocked structures, however, can also offer a novel approach toward molecular recognition: this Account describes the use of rotaxane and catenane host systems for binding charged guest species, and for providing sensing capability through an integrated optical or electrochemical reporter group. Particular attention is drawn to the exploitation of the unusual dynamic properties of interlocked molecules, such as guest-induced shuttling or conformational switching, as a sophisticated means of achieving a selective and functional sensor response. We initially survey interlocked host systems capable of sensing cationic guests, before focusing on our accomplishments in synthesizing rotaxanes and catenanes designed for the more challenging task of selective anion sensing. In our group, we have developed the use of discrete anionic templation to prepare mechanically interlocked structures for anion recognition applications. Removal of the anion template reveals an interlocked host system, possessing a unique three-dimensional geometrically restrained binding cavity formed between the interlocked components, which exhibits impressive selectivity toward complementary anionic guest species. By incorporating reporter groups within such systems, we have developed both electrochemical and optical anion sensors which can achieve highly selective sensing of anionic guests. Transition metals, lanthanides, and organic fluorophores integrated within the mechanically bonded structural framework of the receptor are perturbed by the binding of the guest, with a concomitant change in the emission profile. We have also exploited the unique dynamics of interlocked hosts by demonstrating that an

    Ground-based remote sensing systems have been used during the ESCOMPTE campaign, to continuously characterize the boundary-layer behaviour through many atmospheric parameters (wind, extinction and ozone concentration distribution, reflectivity, turbulence). This analysis is focused on the comparison of the atmospheric stratification retrieved from a UV angular ozone lidar, an Ultra High Frequency wind profiler and a sodar, above the area of Marseille, on June 26th 2001 (Intensive Observation Period 2b). The atmospheric stratification is shown to be very complex including two superimposed sea breezes, with an important contribution of advection. The temporal and spatial evolution of the stratification observed by the UV lidar and by the UHF radar are in good agreement although the origin of the echoes of these systems is quite different. The complexity of the dynamic situation has only partially been retrieved by a non-hydrostatic mesoscale model used with a 3 km resolution.

  3. Distribution of metal and adsorbed guest species in zeolites

    Energy Technology Data Exchange (ETDEWEB)

    Chmelka, B.F.

    1989-12-01

    Because of their high internal surface areas and molecular-size cavity dimensions, zeolites are used widely as catalysts, shape- selective supports, or adsorbents in a variety of important chemical processes. For metal-catalyzed reactions, active metal species must be dispersed to sites within the zeolite pores that are accessible to diffusing reactant molecules. The distribution of the metal, together with transport and adsorption of reactant molecules in zeolite powders, are crucial to ultimate catalyst performance. The nature of the metal or adsorbed guest distribution is known, however, to be dramatically dependent upon preparatory conditions. Our objective is to understand, at the molecular level, how preparatory treatments influence the distribution of guest species in zeolites, in order that macroscopic adsorption and reaction properties of these materials may be better understood. The sensitivity of xenon to its adsorption environment makes {sup 129}Xe NMR spectroscopy an important diagnostic probe of metal clustering and adsorbate distribution processes in zeolites. The utility of {sup 129}Xe NMR depends on the mobility of the xenon atoms within the zeolite-guest system, together with the length scale of the sample heterogeneity being studied. In large pore zeolites containing dispersed guest species, such as Pt--NaY, {sup 129}Xe NMR is insensitive to fine structural details at room temperature.

    Full Text Available Nowadays, the trend of dining in restaurants has become quite prominent in Serbia. Frequent restaurant visits are not only the reflection of satisfying hedonistic needs, but also the result of increasing number of single-person households as well as adjustment to the European business hours.In an increasingly competitive environment, restaurants must be focused on guests using marketing concepts that identify their needs thus leading to their satisfaction and increased retention.Service quality is fundamental component which produce higher levels of guest satisfaction, which in turn lead to higher sales revenue.The main purpose of this study was to examine the quality dimensions that affect guest satisfaction in restaurant industry. Food and beverage quality, the quality of service delivery, physical environment and price fairness are analyzed as a key components of restaurant experience. The results could be helpful tool for restaurant managers to invest their resources more efficiently, making changes to crucial quality attributes that elicit the guests’ satisfaction level. A management approach focused on guest satisfaction can improve restaurant business performance.

    Here we report a cavitand with a photochemical switch as one of the container walls. The azo-arene switch undergoes photoisomerization when subjected to UV light producing a self-fulfilled cavitand. This process is thermally and photochemically reversible. The reported cavitand binds small molecules and these guests can be ejected from the cavitand through this photochemical process.

  6. Distribution of metal and adsorbed guest species in zeolites

    International Nuclear Information System (INIS)

    Chmelka, B.F.

    1989-12-01

    Because of their high internal surface areas and molecular-size cavity dimensions, zeolites are used widely as catalysts, shape- selective supports, or adsorbents in a variety of important chemical processes. For metal-catalyzed reactions, active metal species must be dispersed to sites within the zeolite pores that are accessible to diffusing reactant molecules. The distribution of the metal, together with transport and adsorption of reactant molecules in zeolite powders, are crucial to ultimate catalyst performance. The nature of the metal or adsorbed guest distribution is known, however, to be dramatically dependent upon preparatory conditions. Our objective is to understand, at the molecular level, how preparatory treatments influence the distribution of guest species in zeolites, in order that macroscopic adsorption and reaction properties of these materials may be better understood. The sensitivity of xenon to its adsorption environment makes 129 Xe NMR spectroscopy an important diagnostic probe of metal clustering and adsorbate distribution processes in zeolites. The utility of 129 Xe NMR depends on the mobility of the xenon atoms within the zeolite-guest system, together with the length scale of the sample heterogeneity being studied. In large pore zeolites containing dispersed guest species, such as Pt--NaY, 129 Xe NMR is insensitive to fine structural details at room temperature

    2005-03-01

    Global Positioning System (GPS) tomography analyses of water vapor, complemented by high-resolution numerical simulations are used to investigate a Mistral/sea breeze event in the region of Marseille, France, during the ESCOMPTE experiment. This is the first time GPS tomography has been used to validate the three-dimensional water vapor concentration from numerical simulation, and to analyze a small-scale meteorological event. The high spatial and temporal resolution of GPS analyses provides a unique insight into the evolution of the vertical and horizontal distribution of water vapor during the Mistral/sea-breeze transition.

    POPA LUMINITA

    2010-12-01

    Full Text Available It is considered that a weakness of the Romanian tourism offer is the quality of guest services. In this paper we established as an objective to examine in detail the importance given by the consumers to the components of guest service quality and their perceived performance, based on the three pillars of service quality: the material base (equipments, staff training and staff behavior. The emphasis is on the investigation regarding staff training and behaviour, taking into account the multiple attributes SERVQUAL scale. On the basis of this work lies a survey done in March-April 2010 on the population of Oradea, on a sample of 1060 people. Results confirm the importance granted to staff in ensuring quality of tourism services and their perceived relatively weak performance.

  4. Usability of Security Management:Defining the Permissions of Guests

    Science.gov (United States)

    Johnson, Matthew; Stajano, Frank

    Within the scenario of a Smart Home, we discuss the issues involved in allowing limited interaction with the environment for unidentified principals, or guests. The challenges include identifying and authenticating guests on one hand and delegating authorization to them on the other. While the technical mechanisms for doing so in generic distributed systems have been around for decades, existing solutions are in general not applicable to the smart home because they are too complex to manage. We focus on providing both security and usability; we therefore seek simple and easy to understand approaches that can be used by a normal computer-illiterate home owner, not just by a trained system administrator. This position paper describes ongoing research and does not claim to have all the answers.

  5. Supramolecular polymeric materials via cyclodextrin-guest interactions.

    Science.gov (United States)

    2014-07-15

    CONSPECTUS: Cyclodextrins (CDs) have many attractive functions, including molecular recognition, hydrolysis, catalysis, and polymerization. One of the most important uses of CDs is for the molecular recognition of hydrophobic organic guest molecules in aqueous solutions. CDs are desirable host molecules because they are environmentally benign and offer diverse functions. This Account demonstrates some of the great advances in the development of supramolecular materials through host-guest interactions within the last 10 years. In 1990, we developed topological supramolecular complexes with CDs, polyrotaxane, and CD tubes, and these preparation methods take advantage of self-organization between the CDs and the polymers. The combination of polyrotaxane with αCD forms a hydrogel through the interaction of αCDs with the OH groups on poly(ethylene glycol). We categorized these polyrotaxane chemistries within main chain type complexes. At the same time, we studied the interactions of side chain type supramolecular complexes with CDs. In these systems the guest molecules modified the polymers and selectively formed inclusion complexes with CDs. The systems that used low molecular weight compounds did not show such selectivity with CDs. The multivalency available within the complex cooperatively enhances the selective binding of CD with guest molecules via the polymer side chains, a phenomenon that is analogous to binding patterns observed in antigen-antibody complexes. To incorporate the molecular recognition properties of CDs within the polymer side chains, we first prepared stimuli-responsive sol-gel switching materials through host-guest interactions. We chose azobenzene derivatives for their response to light and ferrocene derivatives for their response to redox conditions. The supramolecular materials were both redox-responsive and self-healing, and these properties resulted from host-guest interactions. These sol-gels with built in switches gave us insight for

    Particulate polymeric microfibers with incorporated europium(III)oxide (Eu2O3) nanoparticles were introduced as a magneto-photoluminescent multifunctional material fabricated via reversal nanoimprint lithography. To specifically address the volume properties of these guest-host particles, the guest, Eu2O3, was milled down to an average particle size of 350 nm in diameter and mixed with the host-polymer, AMONIL®, before in situ hardening in the imprint stamp. The variation of the fabrication process parameters, i.e. delay time, spin coating speed, as well as the concentration of Eu2O3 nanoparticles was proven to have a significant impact on both the structure quality and the stamp release of the microfibers with respect to the formation of a thinner residual layer. Structural characterization performed by SEM revealed optimum fabrication process parameters for a homogeneous spatial distribution of Eu2O3 nanoparticles within the microfibers while simultaneously avoiding the formation of undesired agglomerates. The magneto-photoluminescent properties of Eu2O3 nanoparticles, i.e. a red emission at 613 nm and a paramagnetic response, were found to be superimposed to the optic and the diamagnetic behaviors of AMONIL®. The results imply that guest-host interdependence of these properties can be excluded and that the suggested technique enables for specific tailoring of particulate multifunctional materials with focus on their volume properties.

  12. Aerosol study and transformations over the Marseille/Fos-Berre region: ESCOMPTE experiment; Etude de l'aerosol et de ses transformations dans la region de Marseille Fos-Berre: experience escompte

    Energy Technology Data Exchange (ETDEWEB)

    Aulagnier, F.

    2003-12-01

    The importance of particulate pollution in urban and suburban zones is getting more and more obvious worldwide. Any policy abatement in relation with the aerosol impact relies on an accurate knowledge of their physico-chemical properties: size, chemical composition and number concentrations. As part of the ESCOMPTE experiment (http://medias.obs-mip.fr:8000/escompte/) which aims to estimate the photochemical pollution in the Marseille Fos/Berre region, this work presents an extensive study of the atmospheric particulate phase and documents its transformations. Interestingly in this region, three intense aerosol sources (urban, industrial and biogenic) produce important particle concentration levels in the whole domain of the study. The aerosol exhaustive characterization has shown an anthropogenic and differentiated signature with important amounts of particulate carbon, sulfate and nitrate. On the other hand, the influence of the marine source is not significant. The most original result is the evidence of secondary aerosol formation on a regional scale which is much more important than those usually observed at these latitudes since two thirds of the particulate mass collected off source zones was generated during transport. It appears thus of high importance to consider the formation pathways of these secondary particles in order to set up an appropriate strategy for the abatement of atmospheric particle concentrations. Finally, this study brings innovative hypotheses for the first modelling tests of aerosol concentrations and their radiative impact. (author)

  13. Managing Guest as an Asset: a Conceptual Review in the Context of Accommodation Services

    Directory of Open Access Journals (Sweden)

    Dwi Suhartanto

    2015-10-01

    Full Text Available This article discusses the concept of a customer as an asset of business in the accommodation industry. The purpose of this article is to examine the value of guests as a firm asset and to propose a model for managing guests as an asset in the context of accommodation services. A guest is considered an asset due to its role in providing revenue to the accommodation firm. Because of this role, the accommodation guest needs to be managed appropriately. This article argues that guest service evaluation (i.e. service quality, perceived value, and guest satisfaction and service loyalty are important factors in the development of guest lifetime value. The proposed model of managing guests as an asset consists of marketing instruments, service evaluation, guest loyalty, and financial outcomes provides a comprehensive guide on how accommodation firms can manage the lifetime value of their guests. Finally, as there are limited studies examining this issue, future research should test the proposed model.

    Science.gov (United States)

    Calmet, Isabelle; Mestayer, Patrice

    2016-02-01

    A revisit of two sea-breeze episodes is presented, based on higher spatial resolution large eddy simulations (LES) of the lower atmosphere over the coastal area of Marseille and measurements obtained during the June 2001 experimental campaign UBL-ESCOMPTE. The focus is on the development of thermal internal boundary layers (TIBL) over a complex topography: the dynamic and thermal mechanisms that contribute to the TIBL growth and its further degeneration into a convective mixed layer, the respective influences of the coast shape, the large-scale flow above and the local low-level slope flows. The high-resolution LES permits exploring the potential temperature and turbulent kinetic energy fields in relation with the evolution of TIBL depth and heat fluxes along representative streamlines. Several theoretical TIBL depth models are further compared to the LES-deduced inversion height and other parameters, leading to a discussion of the relationships between the values of these parameters, the respective influences of the governing physical phenomena, and the TIBL behaviour. A threshold value of 0.35 is proposed for the friction velocity to convective velocity scale ratio u */ w * between the two regimes where the TIBL is either dominated by dynamical kinetic energy production or controlled by buoyancy.

    In 2008, a new species for the French bee fauna was recorded in Allauch near Marseille: the giant resin bee, Megachile sculpturalis (Smith, 1853). This was the first European record of this species that is native to East Asia. To our knowledge, it is the first introduced bee species in Europe. Here, we provide an overview of the current distribution of M. sculpturalis in France and we describe the history of its range expansion. Besides our own observations, information was compiled from literature and Internet websites, and by contacting naturalist networks. We collected a total of 117 records ( locality  ×  year combinations) for the 2008-2016 period. The geographical range of M. sculpturalis has extended remarkably, now occupying a third of continental France, with the most northern and western records located 335 and 520 km from Allauch, respectively. Information on its phenology, feeding, and nesting behavior is also provided. We report several events of nest occupation or eviction of Osmia sp. and Xylocopa sp. individuals by M. sculpturalis . Our results show that M. sculpturalis is now well established in France. Given its capacity to adapt and rapidly expand its range, we recommend amplifying the monitoring of this species to better anticipate the changes in its geographical range and its potential impacts on native bees.

  17. Upgrading France's emergency plans

    International Nuclear Information System (INIS)

    Moures, Y.

    1991-01-01

    In France as elsewhere, the Chernobyl accident spurred a new stage in the development of nuclear safety. In the months following the accident, France's Minister of Industry launched a campaign to strengthen research and safety measures to: prevent reactor accidents; reinforce the concept of quality in operations; train staff, in areas such as crisis management; systematically review plans, installations and techniques related to crisis management; study accident containment procedures. There was also a systematic review of communication links with authorities and outside emergency organizations during the critical phase of an accident. On the operational level regulatory monitoring procedures were reorganized and reinforced. France has not opted for the permanent presence of on-site inspectors, but rather for the total, continuous responsibility of the power plant operator, with the safety authority intervening at frequent intervals. A major programme was also established to increase capabilities for investigation and intervention in a radioactive environment in nuclear installations. (author)

    Full Text Available  Today digital communication is a natural part of young people’s social life. It has increased drastically during the last few years, and there are still a lot of questions about what this means, and how this new media affects communication. This study focuses on young people of 11-13, i.e.the age between children and teenagers, also called tweens. In a large study, the overall aim is to see what communication in the Internet community LunarStorm means to them in their social life. This particular paper reports on the content of the asynchronous communication in the participants’ digital guest books, which is one of the main channels for communication between the participants. A group of 15 tweens from a small village in Sweden were studied when communicating in Sweden’s largest Internet community, LunarStorm. The research method used was what is usually described as cyber ethnography. The contributions in the participants’ digital guest books are not written by the guest book owners themselves, which means that the focus is on the collective aspects of this communication, and not from a specific children’s point of view. Qualitative analyses were made of the content of 947 contributions in the participants’ guest books in order to make a statistical analysis. Most of the participants’ communication was between friends in the same geographical neighbourhood concerning how things are going, what to do, when to meet and similar things. The contributions were divided into three categories: (1 Social chat (2 Chain letters, and (3 Messages incomprehensible to outsiders. The information-category was divided into three sub-categories depending on the emotions expressed. 44% of the total messages were considered as emotionally neutral information, 39% as kind or encouraging, and also with an aim to sort things out, and 6% of the total messages contained insults and elements of anger.

    1995-03-01

    In 1992, Electricite de France - EDF decided to improve the degree to which radiological protection is incorporated in overall management of the utility and set itself the objective of ensuring the same level of protection for workers from contractors as for those from EDF. This decision was taken in a context marked by a deterioration in exposure figures for French plants and by the new recommendations issued by the ICRP. This document describes the policy adopted by EDF at both corporate and plant level to meet these objectives, by: (1) setting up management systems which were responsive but not cumbersome; (2) a broad policy of motivation; (3) the development and use of suitable tools. The document then describes some quite positive results of EDF`s ALARA policy, giving concrete examples and analyzing the changes in global indicators.

    1. Definition of a visa A visa is an administrative document required by the nationals of certain countries to cross a border. The visas referred to in this article ('consular visas') are issued to people who do not live in France (not to be confused with 'exit and/or re-entry visas' issued to people living in France; cf. communiqué of 26 May 1998, ref. CERN/DSU-DO/RH/8283). 2. Types of visa The numerous types of visa include, in particular: short-stay visas, which allow their holders to enter France for a continuous or non-continuous period not exceeding three months in any six; long-stay visas, which are required by those applying for a residence document (Carte spéciale issued by the French Ministry of Foreign Affairs or Carte de séjour issued by a Préfecture). 3.

  11. Wind power in France

    2015-01-01

    After 3 years of steady decreasing, wind power has resumed growth in 2014 in France and the preliminary figures of 2015 confirm this trend. About 1100 MW were installed in 2014 which was almost twice as much as it was installed the year before. This renaissance is mostly due to the implementation of Brottes' law that eases the installations of wind farms by suppressing the wind power development areas (that were interfering with regional wind power schemes) and by suppressing the minimum number of 5 turbines for any new wind farms. Another important incentive measure was the announcement in January 2015 of a new financial support scheme in replacement of the policy of guaranteed purchase price for the electricity produced. In 2014 the total wind power produced in mainland France reached 17 TW which represented 3.1% of the production of electricity. (A.C.)

    The author first discusses the potential theoretical production of tidal energy in the world and more particularly in France, and compares this potential production with that of hydroelectric energy. He discusses the existence of potentially interesting sites in France in terms of sizing and exploitation modes. He describes the main associated works for turbines and sea walls, impacts on the environment, on the economy and on employment. He discusses the production possibilities and their cost, and the issue of energy storage. He indicates sites which could be built before 2025: Saint-Brieuc, Portbail-Coutainville or Granville, Mers or Cayeux, Penly or Saint-Valery en Caux. For each of this site, the author describes the project implantation, gives an gross assessment of the construction cost, and therefore of the kWh cost

  14. PPII propensity of multiple-guest amino acids in a proline-rich environment.

    2011-07-07

    There has been considerable debate about the intrinsic PPII propensity of amino acid residues in denatured polypeptides. Experimentally, this scale is based on the behavior of guest amino acid residues placed in the middle of proline-based hosts. We have used classical molecular dynamics simulations combined with replica-exchange methods to carry out a comprehensive analysis of the conformational equilibria of proline-based host oligopeptides with multiple guest amino acids including alanine, glutamine, valine, and asparagine. The tracked structural characteristics include the secondary structural motifs based on the Ramachandran angles and the cis/trans isomerization of the prolyl bonds. In agreement with our recent study of single amino acid guests, we did not observe an intrinsic PPII propensity in any of the guest amino acids in a multiple-guest setting. Instead, the experimental results can be explained in terms of (i) the steric restrictions imposed on the C-terminal guest amino acid that is immediately followed by a proline residue and (ii) an increase in the trans content of the prolyl bonds due to the presence of guest residues. In terms of the latter, we found that the more guests added to the system, the larger the increase in the trans content of the prolyl bonds, which results in an effective increase in the PPII content of the peptide.

  15. [Primary care in France].

    The poor planning of health care professionals in Spain has led to an exodus of doctors leaving the country. France is one of the chosen countries for Spanish doctors to develop their professional career. The French health care system belongs to the Bismarck model. In this model, health care system is financed jointly by workers and employers through payroll deduction. The right to health care is linked to the job, and provision of services is done by sickness-funds controlled by the Government. Primary care in France is quite different from Spanish primary care. General practitioners are independent workers who have the right to set up a practice anywhere in France. This lack of regulation has generated a great problem of "medical desertification" with problems of health care access and inequalities in health. French doctors do not want to work in rural areas or outside cities because "they are not value for money". Medical salary is linked to professional activity. The role of doctors is to give punctual care. Team work team does not exist, and coordination between primary and secondary care is lacking. Access to diagnostic tests, hospitals and specialists is unlimited. Duplicity of services, adverse events and inefficiencies are the norm. Patients can freely choose their doctor, and they have a co-payment for visits and hospital care settings. Two years training is required to become a general practitioner. After that, continuing medical education is compulsory, but it is not regulated. Although the French medical Health System was named by the WHO in 2000 as the best health care system in the world, is it not that good. While primary care in Spain has room for improvement, there is a long way for France to be like Spain. Copyright © 2015 Sociedad Española de Médicos de Atención Primaria (SEMERGEN).

    In France, to practice as a pharmacist, one needs a "diplome d'état de Docteur en Pharmacie" This degree is awarded after 6 or 9 years of pharmacy studies, depending on the option chosen by the student. The degree is offered only at universities and is recognized in France as well as throughout the European Union. Each university in France is divided into faculties called Unité de Formation et de Recherche (UFR). There are 24 faculties of pharmacy or UFRs de pharmacie. A national committee develops a pharmacy education program at the national level and each faculty adapts this program according to its specific features and means (eg, faculty, buildings). The number of students accepted in the second year is determined each year by a Government decree (numerus clausus). Successive placements, totalling 62 weeks, progressively familiarize the student with professional practice, and enable him/her to acquire the required competencies, such as drug monitoring and educating and counselling patients. Challenges facing community pharmacies in the next 10 years are patient education, home health care, and orthopaedics; in hospital pharmacies, empowering pharmacists to supervise and validate all prescriptions; and finally, research in pharmacy practice.

    This series of slides draws a picture of nuclear engineering training in France. The nuclear sector is very active and developed in France and covers all the aspects of the fuel cycle which implies a strong demand for highly skilled and trained staff. There are both an active involvement of industry in the education process through the design of adequate curricula and a strong support of the State. There are 5 masters dedicated to Science Nuclear Energy (Paris), Nuclear Waste Management (Nantes), Separation Chemistry (Montpellier), Materials for Nuclear Engineering (Grenoble), and 1 engineer degree in nuclear engineering (Saclay). In 2010-2011 there were about 1000 students completing a nuclear energy curriculum (nuclear engineering or specialized nuclear domains) at the master-engineer level throughout France. The detailed curriculum of the Master of Science Nuclear Energy is given. The National Institute of Nuclear Sciences and Techniques (INSTN) plays an important role, it has trained a large fraction of the French leading nuclear practitioners through its 50 years old 'Genie Atomique' curriculum. INSTN proposes also high level courses in nuclear disciplines including training of nuclear physicians, radio-pharmacists and medical physicists and is a major player for continuing education in nuclear sciences.

    The rapid rise of oil price and the future shortage of oil are the problems, to which those in charge of energy must face. The method of maintaining and increasing energy consumption without destroying financial balance must be found. As the common points in Japan and France, domestic energy resources are scarce, coal reserves are small and the cost is high, the room for expanding water power generation hardly remains, and the atomic energy projects of large scale seem to be the only solution, but actually, they encountered many difficulties. In France, Energy Conservation Agency was established in 1974. The energy consumption per man was 4500 kWh in 1979, and it is not high level, accordingly it is difficult to reduce the present consumption further. The growth of electricity consumption in 1979 slowed down remarkably. The present crisis is oil crisis instead of energy crisis. Therefore electric power is the most suitable medium to get rid of the bondage of oil. The breakdown of heat production is as follows: coal 41%, oil 32%, gas 4%, and uranium 23%. Since 1976, 15 power plants of 3.5 million kW were converted to coal burning, but more staffs are required for the operation and maintenance. Water power generation is valuable to supplement nuclear power generation which lacks flexibility. As the nucleus of energy projects in France, PWR development project is in progress. Six 900 MW PWR plants are in operation. (Kako, I.)

    A proof-of-concept related to the redox-control of the binding/releasing process in a host-guest system is achieved by designing a neutral and robust Pt-based redox-active metallacage involving two extended-tetrathiafulvalene (exTTF) ligands. When neutral, the cage is able to bind a planar polyaromatic guest (coronene). Remarkably, the chemical or electrochemical oxidation of the host-guest complex leads to the reversible expulsion of the guest outside the cavity, which is assigned to a drastic change of the host-guest interaction mode, illustrating the key role of counteranions along the exchange process. The reversible process is supported by various experimental data ( 1 H NMR spectroscopy, ESI-FTICR, and spectroelectrochemistry) as well as by in-depth theoretical calculations performed at the density functional theory (DFT) level. © 2017 Wiley-VCH Verlag GmbH & Co.

    Recent X-ray crystal structural data for two novel 1:2 host-guest complexes of 18-crown-6 with neutral organic molecules, thiaamide hydrazide of 2-aminobenzoic acid and thiaamide hydrazide of 4-amino-1,2,5-thiadiazole-3-carbonic acid are reported. The supramolecular structures of these two and five relative complexes are discussed from the point of view of participation of donor groups in coordination with the crown ether, and donor and acceptor groups in the self-assembly of the guest molecules. Guest molecules have incorporated amine and hydrazine moieties as proton donors and carbonyl oxygen and sulfur (in thiadiazole and in thiaamine moieties) as proton acceptors. The guest-guest interactions appeared to be crucial in the final architecture.

    2013-02-01

    Full Text Available New host-guest materials have been prepared by incorporation of a home-made organic probe displaying a pyrene motif and a phosphonate function into a regular amphiphilic copolymer. Using powder X-Ray diffraction, photoluminescence and FT-IR spectroscopy, we have been able to study the non-covalent interactions between the host matrix and the guest molecule in the solid state. Interestingly, we have shown that the matrix directs the guest spatial localization and alters its properties. Thanks to the comparison of pyrene vs. N-pyrenylmaleimide derivatives, the influence of the chemical nature of the guest molecules on the non-covalent interactions with the host have been studied. In addition, using polyethylene glycol as a reference host, we have been able to evidence a true matrix effect within our new insertion materials. The phosphonated guest molecule appears to be a novel probe targeting the hydrophilic domain of the host copolymer.

In two hotels in Germany (Study 1: N = 724; Study 2: N = 204, descriptive norm messages suggesting that 75% of guests had reused their towels, or a standard message appealing to environmental concerns, were placed in guests' bathrooms. Descriptive norm messages varied in terms of proximity of the reference group ("hotel guests" vs. "guests in this room" and temporal proximity (currently vs. two years previous. Reuse of towels was unobtrusively recorded. Results showed that reuse rates were high overall and that both standard and descriptive norm messages increased reuse rates compared to a no-message baseline. However, descriptive norm messages were not more effective than the standard message, and effects of proximity were inconsistent across studies. Discussion addresses cultural and conceptual issues in comparing the present findings with previous ones.

    2013-10-01

    Full Text Available During the last years, tourists started to turn away from the mass tourism and consider the alternative one. Therefore, various forms of tourism were born, among which the rural tourism, to be regarded from two perspectives: it contributes to local and regional development and brings benefits to tourism by creating a new, higher quality holiday concept. This requires the participation of local authorities in the preparing of area development strategies, involving the inhabitants and local traders. By following up the dramatic condition of the Romanian tourism, the insufficient development of the rural tourism and the low involvement degree of the local authorities, we proposed an assessment and recommended strategic marketing alternatives for the improvement of the current condition of the agro tourism guest houses.

    A.E. Kazak's (2006) call to develop theory-driven and empirically supported programs aimed at strengthening the competencies of families affected by pediatric illness applies to both medical and nonmedical facilities and institutions that care for pediatric patients and their loved ones. M.K.W. Duncan and A. Blugis (in press, this issue) note that despite the intuitive and practical nature of Maslow's Hierarchy of Needs, no theory translates into an infallible understanding of any individual guest's needs or a program of universally applied best practice standards for meeting those needs. Using Maslow's theory as a framework, this brief report describes the complexity and fluidity of one mother's needs during her stay at a hospitality house following the birth of her premature twin babies.

    2016-12-01

    Full Text Available For an Italian guest, getting to know Slovenia as a tourist destination is inevitably connected with getting to know the Slovenian cuisine. Italians are a nation eagerly developing the culture of food, and therefore the gastronomic offer in a certain environment and at a certain time is for them often the basis for a comprehensive perception of the said destination. A good offer, a suitable marketing and an attractive presentation of typical Slovenian dishes play an important role in getting to know natural and cultural heritage as they can widen the knowledge about people and places, eliminate prejudice and strengthen intercultural cooperation. Kind and professional staff, knowledge of the language, civilisation, cultural habits, and differences may be the factors contributing to the assertion of local products and services, and to educating the users of restaurant and tourism services.

  10. Exchanges in boundary layer and low troposphere and consequences on pollution of Fos-Berre-Marseille area (ESCOMPTE experiment); Les aerosols: emissions, formation d'aerosols organiques secondaires, transport longue distance. Zoom sur les aerosols carbones en Europe

    Energy Technology Data Exchange (ETDEWEB)

    Guillaume, B

    2006-01-15

    There are two types of 'carbonaceous aerosols': 'black carbon' (BC) and 'organic carbon'(OC). BC is directly emitted in the atmosphere while OC is either directly emitted (primary OC, OCp) or secondarily formed through oxidation processes in the atmosphere (secondary organic aerosols, SOA). Complexity of carbonaceous aerosols is still poorly represented in existing aerosol models and uncertainties appear mainly both in their emission inventories and in their complex atmospheric evolution (transport, gas-particle interactions, dry/wet deposition), making difficult the estimation of their radiative impact. In this framework, I developed during my PhD at Laboratoire d'Aerologie, a new approach to deal with this complexity, with implementation of both a new carbonaceous aerosol emission inventory and a new aerosol modelling tool at global scale. My work is divided in 5 different tasks: - better characterisation of BC and OCp emissions, achieved through the development of a new emission inventory from fossil fuel and biofuel combustion sources (industrial, domestic and mobile sources). This inventory provides BC and OCp emissions for Europe at 25 km * 25 km resolution for the years 1990, 1995, 2000, 2005 and 2010, with two additional regional zooms: on France, at 10 km * 10 km resolution for the years 2000 and 2010 with improved road traffic, and in Marseille region (Escompte campaign, 1999,-2001) at 1 km * 1 km resolution for the year 1999; - better modelling of carbonaceous aerosol complex atmospheric evolution, through coupling of a global scale gas transport/chemistry model (TM4) with an aerosol module (ORISAM) featuring size-distributed aerosols (on 8 diameter sections from 40 nm to 10 {mu}m) organic/inorganic chemical composition and explicit treatment of SOA formation; - simulations with this new aerosol model ORISAM-TM4 and model/measurements comparisons to study BC and OC long-range transport; - sensitivity tests on SOA

  11. A Tunable Cyclic Container: Guest-Induced Conformational Switching, Efficient Guest Exchange, and Selective Isolation of C70 from a Fullerene Mixture.

    Mondal, Pritam; Rath, Sankar Prasad

    2017-07-18

    An adaptable cyclic porphyrin dimer with highly flexible linkers has been used as an artificial molecular container that can efficiently encapsulate various aromatic guests (TCNQ/C 60 /C 70 ) through strong π-π interactions by adjusting its cavity size and conformation. The planar aromatic guest (TCNQ) can be easily and selectively exchanged with larger aromatic guests (C 60 /C 70 ). During the guest-exchange process, the two porphyrin rings switch their relative orientation according to the size and shape of the guests. This behavior of the cyclic container has been thoroughly investigated by using UV/Vis spectroscopy, NMR spectroscopy, and X-ray crystal structure determination of the host-guest assemblies. The electrochemical and photophysical studies demonstrated the occurrence of photoinduced electron transfer from bisporphyrin to TCNQ/C 60 /C 70 in the respective host-guest assemblies. The cyclic host can form complexes with C 60 and C 70 with association constants of (2.8±0.2)×10 5 and (1.9±0.3)×10 8  m -1 , respectively; the latter value represents the highest binding affinity for C 70 reported so far for zinc(II) bisporphyrinic receptors. This high selectivity for the binding of C 70 versus C 60 allows the easy extraction and efficient isolation of C 70 from a C 60 /C 70 fullerene mixture. Experimental evidence was substantiated by DFT calculations. © 2017 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim.

    A novel homochiral zeolite-like metal-organic framework (ZMOF), [(Cu4I4) (dabco)2]·[Cu2(bbimb)]·3DMF (JLU-Liu23, dabco =1,4-diazabicyclo[2.2.2]-octane, H2bbimb =1,3-bis(2-benzimidazol)benzene, DMF = N,N-dimethylformamide), has been successfully constructed to host unprecedented DNA-like [Cu2(bbimb)]n polymers with double-helicity. The host-guest chirality interplay permitted the induced formation of an unusual gyroid MOF with homochirality and helical channels in the framework for the first time, JLU-Liu23. Importantly, the enantiomeric pairs (23P, 23M) can be promoted and isolated in the presence of appropriate chiral inducing agents, affording enantioselective separation of chiral molecules as well as small gas molecules. © 2016 American Chemical Society.

    A major theme running through the Cornell meeting, as with most physics meetings these days, was the need to look hard at suppressed or forbidden reactions for signs of an excess or positive signal, suggesting that at last something new might be happening. At Cornell, Jack Ritchie (Texas) covered the kaon front, while Anthony Sanda (Nagoya) gave an overall status report. Rare processes mediated by second order effects (two quarks mechanisms coupled back-to-back) have been seen by the CLEO detector at Cornell (June page 1), and Sanda suggested that other such effects could now begin to show up. Last year's major international meeting at Dallas marked the debut of physics results from the Zeus and H1 experiments at the new and unique HERA electron-proton collider at DESY, Hamburg. This year HERA's collision rate is climbing, and the entire 1992 collision score was matched in just one weekend at the end of July. Cornell's plenary-only programme featured back-to-back presentations from H1 (John Dainton, Liverpool) and Zeus (John Martin, Toronto). Both experiments are beginning to see signs of the tight particle clusters ('jets') indicative of constituent quark/ gluon interactions deep inside the 'target' protons. HERA probes the structure of the proton in an unexplored kinematical region (quark momentum fraction x approaching 10 -4 ), and H1 was the first to see how this structure develops as x decreases. As the proton is probed in increasingly finer detail, it shows a richer quark content as more transient ('virtual') quark/gluon contributions come into play. This structure evolution provides important information for quark field theory, with additional mechanisms opening up

    The aim of postmortem medicolegal examination in pediatric death is primarily to establish the circumstances and causes of death and to exclude child abuse. In France, pediatric death is systematically documented by medicolegal or medical autopsy. In case of medicolegal autopsy, the complementary examinations, requested and financed by justice, are rarely limited to a histopathological examination. However in medical autopsies other tools are available to the pathologist as toxicology, biochemistry and molecular biology. The purpose of this article is to evaluate the efficacy of forensic histopathology in pediatric forensic autopsies. We analyze the main causes of pediatric death in a forensic context. Between 2004 and 2015, 157 infant deaths were identified in Marseille university hospital. The forensic histopathology and autopsy reports of all 157 cases were available for systematic review. Medical or surgical causes represented 41,3% of deaths in our center, accidental causes 8.1% and child abuse 28,8%. The definitive diagnosis was made at autopsy in 30% of cases and at histopathological examination in 70% highlighting that forensic histopathology is an indispensable tool in pediatric medicolegal autopsies. Significant histological abnormalities may be detected in selected organs such as the brain, lungs, heart, liver, adrenal glands and kidneys in spite of macroscopically normal appearances. This justifies systematic sampling of all organs. Despite the implementation of the French sudden infant death protocol which recommends medical autopsies, too many pediatric autopsies are carried out in a medicolegal context. 30% of the cases remain without diagnosis at the end of the autopsy and histological examination. This number could be reduced by the contribution of others laboratory investigation. Copyright © 2017 Elsevier Ltd and Faculty of Forensic and Legal Medicine. All rights reserved.

  20. Selecting non-classified hotels in Kenya: what really matters for business guests?

    Directory of Open Access Journals (Sweden)

    Full Text Available Non-classified hotels, which comprise small hotels and guest houses, are important accommodation providers offering limited services and products as compared to the classified hotels. Through guest satisfaction, they can achieve repeat business and also get new business through word of mouth from previous guests. The main focus is for the hoteliers to know exactly the determinants of selection of hotels by their guests. In this case, the focus was on non-classified hotels in Mtwapa town at the Kenyan coast. The study adopted a cross-sectional descriptive survey design. Results from this study clearly indicate that all aspects of hotel operations are important to business guests’ selection of a non-classified hotel. However, it was revealed that this was not on equal basis. Results indicate that the core product (guestroom comfortability, hygiene and cleanliness were the most important factors in determining guests’ selection of where to stay. This research therefore suggests that any efforts towards quality improvement in a hotel should focus primarily on ensuring customer satisfaction with the guestroom. While acknowledging the importance of all aspects of hotel operations, managers should recognize the importance of the guestroom and its facilities towards hotel selection and overall customer satisfaction. Therefore, it is imperative that managers channel their resources towards improving guest services in the guestrooms in accordance with the requirements of the clientele. This includes such aspects as the look of the guest rooms, facilities provided in the guest rooms and comfortability of the bed and mattress.

    Understanding guest diffusion in nanoporous host-guest systems is crucial in the efficient design of metal-organic frameworks (MOFs) for chemical separation and drug delivery applications. In this work, we investigated the effect of molecule length on the diffusion rate in the zeolitic imidazolate framework 8 (ZIF-8), trying to find a simple and straightforward variable to characterize the complicated guest diffusion. We found that, counter-intuitively, long guest molecules can diffuse as quickly as short molecules; the diffusion coefficient of ethyl acetate for example is of the same order of magnitude as ethane and ethanol, as excludes the existence of a simple relationship between molecule length and diffusion rate. This phenomenon is explained by a study of the contributions of intra- and inter-cage movement to overall transport. Steric confinement limits the degrees of freedom of long guest molecules, shortening their residence time and increasing the efficiency of radial diffusion. In contrast, shorter molecules meander within MOF cages, reducing transport. Furthermore, the energy barrier of inter-cage transport also does not exhibit a simple dependence on a guest molecule length, attributing to the effect of the type of functional group on diffusion. Guests over varying lengths were investigated by using theoretical methods, revealing that the guest diffusion in ZIF-8 depends on the number of contiguous carbon atoms in a molecule, rather than its overall length. Thus, we proposed simple criteria to predict arbitrary guest molecule diffusivity in ZIF-8 without time-consuming experimentation. © 2016 The Royal Society of Chemistry.

    As coal production declined and France found herself in a condition of energy dependency, the country decided to turn to nuclear power and a major construction program was undertaken in 1970. The consequences of this step are examined in this article, by imagining where France would be without its nuclear power. At the end of the sixties, fuel-oil incontestably offered the cheapest way of producing electricity; but the first petroleum crisis was to upset the order of economic performance, and coal then became the more attractive fuel. The first part of this article therefore presents coal as an alternative to nuclear power, describing the coal scenario first and then comparing the relative costs of nuclear and coal investment strategies and operating costs (the item that differs most is the price of the fuel). The second part of the article analyzes the consequences this would have on the electrical power market, from the supply and demand point of view, and in terms of prices. The third part of the article discusses the macro-economic consequences of such a step: the drop in the level of energy dependency, increased costs and the disappearance of electricity exports. The article ends with an analysis of the environmental consequences, which are of greater and greater concern today. The advantage here falls very much in favor of nuclear power, if we judge by the lesser emissions of sulfur dioxide, nitrogen oxides and especially carbon dioxide. 22 refs.; 13 figs.; 10 tabs

  5. Perception of service quality in agrotourism accommodations: Impact on guest loyalty and re-visit intentions

    2017-03-01

    Full Text Available This study presents the development of a conceptual model that demonstrates the dynamic nature of the relationship between service quality and guest satisfaction in the agrotourism accommodation sector, based on theories derived from social psychology and previous research in the marketing, management, and services literature. The model was tested using sample data from guests of four different agrotourism firms, and was modified because of empirical results. The final model improves understanding of the relationship between service quality and guest satisfaction because these constructs were examined from the process perspective of an agrotourism accommodation experience; it portrays service quality and satisfaction in the context of a complete system.

    France is deciding how to regulate electronic cigarettes. I first consider the French approach and how it contrasts with other attempts at electronic cigarette regulation globally. Next, I critique the individual elements of the French proposal. The overall approach taken by France is a positive development, but banning indoor use appears unnecessary and banning advertising may be counterproductive.

    At the present time, then, we are on the threshold of the second phase of nuclear development, in the. course of which nuclear activities will play a more telling role in the economic cycle. We must therefore consider the development of nuclear energy during its first two decades in the light of the above conclusions and in the realization that for some time to come we shall find ourselves in a delicate transitional stage, during which various influences from the period behind us and the period ahead will make themselves felt. This train of events is not restricted to France, where in 1970 the CEA undertook a complete restructuring of its departments. It is also taking place in other countries, where the various atomic energy commissions are feeling the need to reorganize in order to fit themselves for essential changes. We must therefore be prepared to act in the most effective way possible during this nuclear industrial period. To this end we must establish structures and adopt ways of thinking that art in keeping with the objectives of the period, which will be accompanied by a large growth of investment in the peaceful uses of nuclear energy. Success will depend to a large extent on timely joint efforts in the public and private sectors. Taken together, these requirements imply that we must follow a long-term policy covering at least the next 20 years. As our remarks are to concern the peaceful applications of nuclear energy in France, leaving aside questions of fundamental research and military applications, we shall concentrate ori the fuel cycle and the production of nuclear power, enlarging the subject at each step to encompass the necessary and increasing international co-operation.

    Energy Technology Data Exchange (ETDEWEB)

    Lafore, P

    1964-10-01

    Shielding research as an independent subject in France dates from 1956. The importance of these studies has been reflected in the contribution which they have made to power reactor design and in the resultant savings in expenditure for civil engineering and machinery for the removal of mobile shields. The Reactor Shielding Research Division numbers approximately 60 persons and uses several experimental facilities. These include: NAIADE I, installed near the ZOE reactor and operating with a natural uranium slab 2 cm thick (an effective diameter of 60 cm is the one most commonly used); the TRITON pool-type reactor, mainly used in shielding studies, includes an active-water loop, by means of which the secondary shields required for light-water reactors can be studied; core, NEREIDE, which is situated near a 2 m x 2 m aluminium window enables a large neutron source to be placed in a compartment without water in which large-scale mock-ups can be mounted for the study, in particular, of neutron diffusion in large cavities, and of reactor shielding of greater thickness than that in NAIADE I; SAMES 600 keV accelerator is used for monoenergetic neutron studies. Instrumentation studies are an important part of the work, mainly in the measurement of fast neutrons and their spectra by activation detectors. Of late, attention has been directed towards the use of (n, n') (rhodium) reactions and of heavy detectors for low-flux measurements. The simultaneous use of a large number of detectors poses automation problems. With our installation we can count 16 detectors simultaneously. Neutron spectrum studies are conducted with nuclear emulsions and a lithium-6 semiconductor spectrometer. As to the materials used, the research carried out in France involves chiefly graphite, iron and concrete at various temperatures up to 800 deg C. Different compounds, borated and non-borated and of densities up to between 1 and 9 are under consideration. Problems connected with applications are

    Full Text Available Authors demonstrate the use of cluster analysis in finding out (ascertaining the homogenity/heterogenity of guests as to the degree of their demand. The degree of guests’ demand is defined according to the importance of perceived service quality components measured by SERVQUAL, which was adopted and adapted, according to the specifics of health spa industry in Slovenia. Goals of the article are: (a the identification of the profile of importance of general health spa service quality components, and (b the identification of groups of guests (segments according to the degree of their demand in the research in 1991 compared with 1999. Cluster analysis serves as useful tool for guest segmentation since it reveals the existence of important differences in the structure of guests in the year 1991 compared with the year 1999. The results serve as a useful database for management in health spas.

    Recognition and binding of anions in water is difficult due to the ability of water molecules to form strong hydrogen bonds and to solvate the anions. The complexation of two different carboxylates with 1-(4-carbomethoxypyrrolidone)-terminated PAMAM dendrimers was studied in aqueous solution using...... the carboxylate-dendrimer interaction selectively. The binding stoichiometry for 3-hydroxy-2-naphthoate was found to be two strongly bound guest molecules per dendrimer and an additional 40 molecules with weak binding affinity. The NOESY NMR showed a clear binding correlation of sodium 3-hydroxy-2-naphthoate...... with the lyophilic dendrimer core, possibly with the two high affinity guest molecules. In comparison, sodium 2-naphthoate showed a weaker binding strength and had a stoichiometry of two guests per dendrimer with no additional weakly bound guests. This stronger dendrimer interaction with sodium 3-hydroxy-2...

By introducing guest molecules into the resulting composite chiral nanochannels, we explore the structures and functionality of the ordered guest/host LC complex, verifying the smectic-like positional order of the fluidic nematic LC phase, which is obtained by the combination of the LC organization and the nanoporous AAO superstructure. The guest nematic LC 4'- n -pentyl-4-cyanobiphenyl is found to form a distinctive fluid layered ordered LC complex at the nanofilament/guest interface with the host 1,3-phenylene bis[4-(4-nonyloxyphenyliminomethyl)benzoate], where this interface contacts the AAO cylinder wall. Filament growth form is strongly influenced by mixture parameters and pore dimensions.

    A general approach toward the light-induced guest release from cucurbit[7]uril by means of a photoactivatable competitor was devised. An o-nitrobenzyl-caged competitor is photolyzed to generate a competitive guest that can displace cargo from the host macrocycle solely based on considerations of chemical equilibrium. With this method the release of terpene guests from inclusion complexes with cucurbit[7]uril was demonstrated. The binding of the herein investigated terpenes, all being lead fragrant components in essential oils, has been characterized for the first time. They feature binding constants of up to 10 8  L mol -1 and a high differential binding selectivity (spanning four orders of magnitude for the binding constants for the particular set of terpenes). By fine-tuning the photoactivatable competitor guest, selective and also sequential release of the terpenes was achieved. © 2017 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim.

    Full Text Available The subject of this study is focused on new migration tendencies of retired guest workers. This paper represents one part of a study conducted during 2014 in eastern Serbia and Vienna regarding life strategies of retired labor migrants. In domestic (Serbian social sciences this subject was neglected, but recently it has attracted global social scientific attention with an idea of interdisciplinary merge of migration and age studies. To the day, global literature has only covered retired migrant laborers return to their home countries, but recent studies show changes in migration tendencies of retired laborers of many different nationalities, who have spent their work age in Western Europe. These new migration patterns were called “oscillatory movement” or as a new, alternative “third option”. They are only a form of seasonal and circular migrations which present the most dominant fashion of modern migrant mobility in Europe. Therefore we wanted to see what is the situation with labor migrants from Serbia – do they return to Serbia once they retire or not, and what are their reasons for choosing to live on “two addresses”.

    In this study, we aimed to investigate the effects cohesion of small surface-engineered guest binder particles on the flow behaviour of interactive mixtures. Polyvinylpyrrolidone (PVP) - a model pharmaceutical binder - was spray-dried with varying l-leucine feed concentrations to create small surface-engineered binder particles with varying cohesion. These spray-dried formulations were characterised by their particle size distribution, morphology and cohesion. Interactive mixtures were produced by blending these spray-dried formulations with paracetamol. The resultant blends were visualised under scanning electron microscope to confirm formation of interactive mixtures. Surface coverage of paracetamol by guest particles as well as the flow behaviour of these mixtures were examined. The flow performance of interactive mixtures was evaluated using measurements of conditioned bulk density, basic flowability energy, aeration energy and compressibility. With higher feed l-leucine concentrations, the surface roughness of small binder particles increased, while their cohesion decreased. Visual inspection of the SEM images of the blends indicated that the guest particles adhered to the surface of paracetamol resulting in effective formation of interactive mixtures. These images also showed that the low-cohesion guest particles were better de-agglomerated that consequently formed a more homogeneous interactive mixture with paracetamol compared with high-cohesion formulations. The flow performance of interactive mixtures changed as a function of the cohesion of the guest particles. Interactive mixtures with low-cohesion guest binder particles showed notably improved bulk flow performance compared with those containing high-cohesion guest binder particles. Thus, our study suggests that the cohesion of guest particles dictates the flow performance of interactive mixtures. Crown Copyright © 2016. Published by Elsevier B.V. All rights reserved.

  10. Incommensurate host-guest structures in compressed elements: Hume—Rothery effects as origin

    International Nuclear Information System (INIS)

    Degtyareva, V F

    2015-01-01

    Discovery of the incommensurate structure in the element Ba under pressure 15 years ago was followed by findings of a series of similar structures in other compressed elements. Incommensurately modulated structures of the host-guest type consist of a tetragonal host structure and a guest structure. The guest structure forms chains of atoms embedded in the channels of host atoms so that the axial ratio of these subcells along the c axis is not rational. Two types of the host-guest structures have been found so far: with the host cells containing 8 atoms and 16 atoms; in these both types the guest cells contain 2 atoms. These crystal structures contain a non-integer number of atoms in their unit cell: tI11* in Bi, Sb, As, Ba, Sr, Sc and tI19* in Na, K, Rb. We consider here a close structural relationship of these host-guest structures with the binary alloy phase Au 3 Cd 5 -tI32. This phase is related to the family of the Hume-Rothery phases that is stabilized by the Fermi sphere-Brillouin zone interaction. From similar considerations for alkali and alkaline-earth elements a necessary condition for structural stability emerges in which the valence electrons band overlaps with the upper core electrons and the valence electron count increases under compression.

    Full Text Available The aim of this study was to investigate guest profiles at a hotel that has created a best-practices water management model to determine how different types of guests contribute to saving water during their stay. To do this, we analyzed levels of environmental awareness and pro-environmental behavior among the guests. Information was gathered through 648 structured surveys with guests at Hotel Samba in the Spanish seaside resort of Lloret de Mar between September 2015 and August 2016. Cluster analysis revealed four profiles of guests with different sociodemographic characteristics and different levels of awareness and proactivity in relation to water conservation. We combined our findings to develop a framework that illustrates how the two dimensions of environmental awareness and pro-environmental behavior are related in this setting. This article provides new insights into how hotel guests’ environmental awareness and engagement can influence a hotel’s water-saving efforts. These insights should help hotel operators to devise new, guest-centered strategies for saving water.

    The molecular structure of the self-assembled supramolecular assembly [M{sub 4}L{sub 6}]{sup 12-} has been explored with different metals (M = Ga{sup III}, Fe{sup III}, Ti{sup IV}) and different encapsulated guests (NEt{sub 4}{sup +}, BnNMe{sub 3}{sup +}, Cp{sub 2}Co{sup +}, Cp*{sub 2}Co{sup +}) by X-ray crystallography. While the identity of the metal ions at the vertices of the M{sub 4}L{sub 6} structure is found to have little effect on the assembly structure, encapsulated guests significantly distort the size and shape of the interior cavity of the assembly. Cations on the exterior of the assembly are found to interact with the assembly through either {pi}-{pi}, cation-{pi}, or CH-{pi} interactions. In some cases, the exterior guests interact with only one assembly, but cations with the ability to form multiple {pi}-{pi} interactions are able to interact with adjacent assemblies in the crystal lattice. The solvent accessible cavity of the assembly is modeled using the rolling probe method and found to range from 253-434 {angstrom}{sup 3}, depending on the encapsulated guest. Based on the volume of the guest and the volume of the cavity, the packing coefficient for each host-guest complex is found to range from 0.47-0.67.

  13. Force and Stress along Simulated Dissociation Pathways of Cucurbituril-Guest Systems.

    2012-03-13

    The field of host-guest chemistry provides computationally tractable yet informative model systems for biomolecular recognition. We applied molecular dynamics simulations to study the forces and mechanical stresses associated with forced dissociation of aqueous cucurbituril-guest complexes with high binding affinities. First, the unbinding transitions were modeled with constant velocity pulling (steered dynamics) and a soft spring constant, to model atomic force microscopy (AFM) experiments. The computed length-force profiles yield rupture forces in good agreement with available measurements. We also used steered dynamics with high spring constants to generate paths characterized by a tight control over the specified pulling distance; these paths were then equilibrated via umbrella sampling simulations and used to compute time-averaged mechanical stresses along the dissociation pathways. The stress calculations proved to be informative regarding the key interactions determining the length-force profiles and rupture forces. In particular, the unbinding transition of one complex is found to be a stepwise process, which is initially dominated by electrostatic interactions between the guest's ammoniums and the host's carbonyl groups, and subsequently limited by the extraction of the guest's bulky bicyclooctane moiety; the latter step requires some bond stretching at the cucurbituril's extraction portal. Conversely, the dissociation of a second complex with a more slender guest is mainly driven by successive electrostatic interactions between the different guest's ammoniums and the host's carbonyl groups. The calculations also provide information on the origins of thermodynamic irreversibilities in these forced dissociation processes.

    Full Text Available Terrestrial inputs (natural and anthropogenic from rivers, the atmosphere and physical processes strongly impact the functioning of coastal pelagic ecosystems. The objective of this study was to develop a tool for the examination of these impacts on the Marseille coastal area, which experiences inputs from the Rhone River and high rates of atmospheric deposition. Therefore, a new 3D coupled physical/biogeochemical model was developed. Two versions of the biogeochemical model were tested, one model considering only the carbon (C and nitrogen (N cycles and a second model that also considers the phosphorus (P cycle. Realistic simulations were performed for a period of 5 years (2007-2011. The model accuracy assessment showed that both versions of the model were able of capturing the seasonal changes and spatial characteristics of the ecosystem. The model also reproduced upwelling events and the intrusion of Rhone River water into the Bay of Marseille well. Those processes appeared to greatly impact this coastal oligotrophic area because they induced strong increases in chlorophyll-a concentrations in the surface layer. The model with the C, N and P cycles better reproduced the chlorophyll-a concentrations at the surface than did the model without the P cycle, especially for the Rhone River water. Nevertheless, the chlorophyll-a concentrations at depth were better represented by the model without the P cycle. Therefore, the complexity of the biogeochemical model introduced errors into the model results, but it also improved model results during specific events. Finally, this study suggested that in coastal oligotrophic areas, improvements in the description and quantification of the hydrodynamics and the terrestrial inputs should be preferred over increasing the complexity of the biogeochemical model.

    France's Solar Energy Commission has announced a series of measures it is backing to increase the country's production of energy from biomass. Following consultations on suitable equipment, it has decided to go ahead with experiments of 15 systems designed to produce methane from animal wastes. Its eventual target is the production of between 1 million and 1.5 million tons per year of oil equivalent (toe) from this source. Secondly, it has launched a tender for the supply of domestic and industrial heating equipment capable of functioning on straw. It has calculated that the amount of straw available for this end use is in the region of 6 million ton per year, equivalent to about 2 million tons per year toe. Finally, tests are to be carried out in 14 different areas to determine the best variety of Jerusalem artichoke for the production of ethanol. Together with the Institut Francais du Petrole the Commission is building a demonstration unit for the production of acetone/butyric acid by fermentation of sugars from Jerusamlem artichoke and beet roots.

    This second volume of the Berlin series presents the papers and discussion of the eleventh discussion meeting on energy law, for the first time held in Berlin, on May 12-13, 1987. The leading subject of the first conference day, namely electricity imports from France, has since then widely been discussed in the media or at other meetings, although the legal problems or obstacles revealed at this Berlin meeting are far from being solved. There is EdF's wish to export electricity to West Germany on the other hand, and there is the West German coal industry's scepticism on the other hand. Much is at stake for West Germany's national concept of enhanced use of coal for electricity generation, and the related system of subventions. Supply concepts and franchise charges, a standing topic of the power sector for quite a time now, have been discussed on the second conference day. The papers read there gave an account of the situation and also presented some new aspects. (orig./UA) [de

    1981-02-01

    The principles and rules governing the safety of nuclear installations are defined as from three fundamental principles and three practical rules as follows: First principle: the operator is responsible and of the highest order. Second principle: the public authorities exercise their control responsibility with respect to the design, construction and running of the installations. Third principle: nuclear safety, this is to accept that man and his technique are not infallible and that one must be prepared to control the unpredictable. First rule: the installations must include several 'lines of defence' in succession and to the extent where this is possible these must be independent of each other. Second rule: procedures are required and supervised by the Government Departments. Third rule: nuclear safety requires that any incident or anomaly must undergo an analysis in depth and is also based on a standing 'clinical' examination of the installations. The definition is given as to how the public authorities exercise their intervention: terms and conditions of the intervention by the safety authorities, authorization procedures, surveillance of the installations, general technical regulations. Two specific subjects are presented in the addendum, (a) the choice of nuclear power station sites in France and (b) the storage of radioactive wastes [fr

    France's Europort South community lives cheek by jowl with the chemical industry, with major complexes at For, Berre, and Lavera. Xavier Segond, technical adviser at the regional chemical industry association, Le Syndicat General des Industries Chimiques Provence-Alpes-Cote d'Azur Corse (SGIC), says a good relationship has grown over a period of 20 years. Segond describes Arco Chimie as an effective driving force for the Responsible Care effort in the region - partly because its US parent introduced the program on a worldwide basis in 1989, ahead of national industry association Union des Industries Chimiques (UIC; Paris). Arco's F2-billion ($373 million)/year Fos-sur-Mer site makes it a significant player. But in 1986 the company was a complete newcomer. We came to Fos as a US company, we had no Paris headquarters or French president, explains Dominique Lequeux, director/human resources. The community viewed the company with a mixture of curiosity and enthusiasm as a potential employer - about 330 people now work at the site. The day before the officials propylene oxide plant opening, we invited in local people, says Lequeux. That formed a good basis for its Responsible Care community outreach program. Now, schools, professional groups, and political groups make 20-25 plant visits each year

    1988-07-01

    French PWR power plant design relies basically on a deterministic approach. A probabilistic approach was introduced in France in the early seventies to define safety provisions against external impacts. In 1977 an overall safety objective was issued by the safety authority in terms of an upper probability limit for having unacceptable consequences. Additional measures were taken (the ''H'' operating procedures) to complement the automatic systems normally provided by the initial design, so as to safisfy the safety objective. The TMI-2 accident enhanced the interest in confused situations in which possible multiple equipment failure and/or unappropriate previous actions of the operators impede the implementation of any of the existing event-oriented procedures. In such situations, the objective becomes to avoid core-melt by any means available: this is the goal of the Ul symptom-oriented procedure. Whenever a core-melt occurs, the radioactive releases into the environment must be compatible with the feasibility of the off-site emergency plans; that means that for some hypothetical, but still conceivable scenarios, provisions have to be made to delay and limit the consequences of the loss of the containment: the U2, U4 and U5 ultimate procedures have been elaborated for that purpose. For the case of an emergency, a nationwide organization has been set up to provide the plant operator with a redundant technical expertise, to help him save his plant or mitigate the radiological consequences of a core-melt

    Full Text Available Hofmann type clatharates are host-guest compounds with the general formula M(NH32M'(CN4·2G, in which M(NH32M'(CN4 is the host lattice and G is benzene, the guest molecule. In previous studies, host-guest interactions have been investigated by analyzing the RT and LNT vibrational (infrared, far infrared and Raman spectra of these clathrates. All the observed changes in the vibrational spectra of these clathrates are referred to a host-guest interaction originating from weak hydrogen bonding between the ammonia hydrogen atoms from the host lattice and the p electron cloud of the guest (benzene molecules. In order to obtain an insight into the relative importance of the local crystalline field vs. the anharmonicity effects on the spectroscopic properties of the guest species upon enclathration, as well as to explain the observed band shifts and splittings, several quantum theoretical approaches are proposed.

  8. Theoretical model estimation of guest diffusion in Metal-Organic Frameworks (MOFs)

    Zheng, Bin

    2015-08-11

    Characterizing molecule diffusion in nanoporous matrices is critical to understanding the novel chemical and physical properties of metal-organic frameworks (MOFs). In this paper, we developed a theoretical model to fastly and accurately compute the diffusion rate of guest molecules in a zeolitic imidazolate framework-8 (ZIF-8). The ideal gas or equilibrium solution diffusion model was modified to contain the effect of periodical media via introducing the possibility of guests passing through the framework gate. The only input in our model is the energy barrier of guests passing through the MOF’s gate. Molecular dynamics (MD) methods were employed to gather the guest density profile, which then was used to deduce the energy barrier values. This produced reliable results that require a simulation time of 5 picoseconds, which is much shorter when using pure MD methods (in the billisecond scale) . Also, we used density functional theory (DFT) methods to obtain the energy profile of guests passing through gates, as this does not require specification of a force field for the MOF degrees of freedom. In the DFT calculation, we only considered one gate of MOFs each time; as this greatly reduced the computational cost. Based on the obtained energy barrier values we computed the diffusion rate of alkane and alcohol in ZIF-8 using our model, which was in good agreement with experimental test results and the calculation values from standard MD model. Our model shows the advantage of obtaining accurate diffusion rates for guests in MOFs for a lower computational cost and shorter calculation time. Thus, our analytic model calculation is especially attractive for high-throughput computational screening of the dynamic performance of guests in a framework.

    Early chemotherapy might improve the overall outcomes of patients with metastatic non-castrate (i.e., hormone-sensitive) prostate cancer. We investigated the effects of the addition of docetaxel to androgen-deprivation therapy (ADT) for patients with metastatic non-castrate prostate cancer. In this randomised, open-label, phase 3 study, we enrolled patients in 29 centres in France and one in Belgium. Eligible patients were older than 18 years and had histologically confirmed adenocarcinoma of the prostate and radiologically proven metastatic disease; a Karnofsky score of at least 70%; a life expectancy of at least 3 months; and adequate hepatic, haematological, and renal function. They were randomly assigned to receive to ADT (orchiectomy or luteinising hormone-releasing hormone agonists, alone or combined with non-steroidal antiandrogens) alone or in combination with docetaxel (75 mg/m(2) intravenously on the first day of each 21-day cycle; up to nine cycles). Patients were randomised in a 1:1 ratio, with dynamic minimisation to minimise imbalances in previous systemic treatment with ADT, chemotherapy for local disease or isolated rising concentration of serum prostate-specific antigen, and Glass risk groups. Patients, physicians, and data analysts were not masked to treatment allocation. The primary endpoint was overall survival. Efficacy analyses were done by intention to treat. This trial is registered with ClinicalTrials.gov, number NCT00104715. Between Oct 18, 2004, and Dec 31, 2008, 192 patients were randomly allocated to receive ADT plus docetaxel and 193 to receive ADT alone. Median follow-up was 50 months (IQR 39-63).

    As environmental issues (particularly questions associated with the greenhouse effect) become a matter of increasing current concern, the French nuclear power programme can, in retrospect, be seen to have had a highly positive impact upon emissions of atmospheric pollutants. The most spectacular effect of this programme was the reduction of carbon dioxide emissions from 530 million tonnes per annum in 1973 to 387 million tonnes per annum today. Obviously, this result cannot be considered in isolation from the economic consequences of the nuclear power programme, which have been highly significant.The most obvious consequence of nuclear power has been the production of cheap electricity, while a further consequence has been the stability of electricity prices resulting from the increasing self-sufficiency of France in energy supplies (from 22% in 1973 to 49.% in 1992). Moreover, French nuclear industry exports. In 1993, 61.7 TW·h from nuclear production were exported, which contributed F.Fr. 14.2 billion to the credit side of the balance of payment. For the same year, Framatome exports are assessed at about F.Fr. 2 billion, corresponding to manufacturing and erection of heavy components, and maintenance services. Cogema, the French nuclear fuel operator, sold nuclear materials and services for F.Fr. 9.3 billion. Thus, nuclear activities contributed more than F.Fr. 25 billion to the balance of payment. Therefore, a numerical assessment of the macroeconomic impact of the nuclear power programme is essential for any accurate evaluation of the environmental consequences of that programme. For this assessment, which is presented in the paper, the Micro-Melodie macroeconomic and energy supply model developed by the Commissariat a l'energie atomique has been used.

    Among the different news we can find information about the situation of the radiation accidents at the hospital of Epinal in the east of France. The medical surveillance of the irradiated patients has allowed to find others cases of over exposure.These new cases add to a series of events enlightened in this service: 24 patients treated for a prostate cancer between may 2004 and august 2005 have been over exposed of about 20 % because of a bad use of the treatment planning software. 4 hundred patients treated for a prostate cancer between 2001 and 2006 have been over exposed of about 8% by an excessive use of the imaging controlling the positioning during the treatment. Among 4500 patients treated for different cancers between september 1987 and july 2000 and concerned by a programming error of an internal software, 312 patients have received an overexposure of about 7%.

  14. Computations between metallocalix(4)arene host and a series of four oil-based fuel pollutant guests

    Calculations using PM3 and mechanics methods on metallocalix(4)arene hosts (1-10) and substituted dibenzothiophene guests (A-D), which are generally known as oil-based fuel pollutants, show that host-guest formation is energetically favored. Calculations have been carried out for both 1/1 and 1/4 ratios of host/guest. There is no direct bonding between the metal center of the host and the sulfur of the guest in the host-guest complex. Sterically hundered dibenzothiophene guests show similar energies to the unhindered analogs. For calix(4)arenas (5-10) in partial cone conformations and having hydrogen rather than p-tert-butyl groups on the wide rim, host-guest formation occurs within the narrow rim rather than the wide rim. Host-guest association appears to occur via Pie-Pie interactions between host and guest phenyl groups rather than via metal-sulfur bonding. The study has importance especially in oil refining to obtain environmentally safe fuel oils and help supramolecular chemists in designing and synthesizing more sophisticated host molecules for the removal of sulfur from crude oil / refinery oil.

    CONSPECTUS: Host-guest chemistry can greatly improve the selectivity of biomolecule-ligand binding on account of recognition-directed interactions. In addition, functional structures and the actuation of supramolecular assemblies in molecular systems can be controlled efficiently through various host-guest chemistry. Together, these highly selective, strong yet dynamic interactions can be exploited as an alternative methodology for applications in the field of programmable and controllable engineering of supramolecular soft materials through the reversible binding between complementary components. Many processes in living systems such as biotransformation, transportation of matter, and energy transduction begin with interfacial molecular recognition, which is greatly influenced by various external stimuli at biointerfaces. Detailed investigations about the molecular recognition at interfaces can result in a better understanding of life science, and further guide us in developing new biomaterials and medicines. In order to mimic complicated molecular-recognition systems observed in nature that adapt to changes in their environment, combining host-guest chemistry and surface science is critical for fabricating the next generation of multifunctional biointerfaces with efficient stimuli-responsiveness and good biocompatibility. In this Account, we will summarize some recent progress on multifunctional stimuli-responsive biointerfaces and biosurfaces fabricated by cyclodextrin- or cucurbituril-based host-guest chemistry and highlight their potential applications including drug delivery, bioelectrocatalysis, and reversible adsorption and resistance of peptides, proteins, and cells. In addition, these biointerfaces and biosurfaces demonstrate efficient response toward various external stimuli, such as UV light, pH, redox chemistry, and competitive guests. All of these external stimuli can aid in mimicking the biological stimuli evident in complex biological environments

    In 1982, the three Committees (FAO, IAEA, WHO) in charge of examining the documentation relating to applications for authorization reacted favourably to the summary report on the toxicology of irradiated foodstuffs submitted by the CEA. New applications need no longer contain a new toxicological study if the dose is lower than 10 kGy. This liberalization of procedure has encouraged industrialists to prepare application documentations. Technically convincing but economically disappointing experiments have shown that the two existing radiation sterilization facilities are unsuitable for harvested agricultural products. It is therefore advisable to set up units which could meet the requirements of the food industry. In the Marseille region it is planned to build a multipurpose commercial facility and a development facility by 1986. Moreover, a firm in Western France is reported soon to be acquiring an electron accelerator for the radicidation of mechanically pointed and frozen poultry. Concurrently with these activities a large information campaign has been undertaken. However, it is too early to offer to the public products for large-scale human consumption which have been treated with ionizing radiation [fr

  18. France's 2010 energy situation

    International Nuclear Information System (INIS)

    2011-01-01

    2010 in Europe was marked by a moderate economic upturn after the crisis year of 2009, when consumption dropped. At the global level, the energy demand from emerging countries continued to push up prices. In France, 2010 was a year in which the winter months were particularly cold, causing additional consumption for heating of more than 10 per cent, estimated at 4.6 millions tonnes of oil equivalent (Mtoe). National primary energy production was 138.6 Mtoe, 0.2 Mtoe higher than the previous record year 2008. Nearly all forms of energy contributed to the increase. Nuclear power increased its output by 4.6 per cent and was only 5 per cent below its maximum, reached in 2005. Hydro production returned to a regime almost in line with the average. Wind power once again increased significantly (+19%) and photovoltaic electricity tripled, although it still only accounts for 0.6 Mtoe. Extraction of conventional fossil fuels was stable at 2.5 Mtoe. Thermal renewable energy and energy recovered from waste also increased markedly, by 10.7 per cent (+1.7 Mtoe). Total primary energy consumption increased by 3.8 per cent. Once corrected for climatic variations, it increased slightly (+1.7%) but remained well below its pre-crisis level. With 266 Mtoe it was even below its 2000 level. It progressed by 4 Mtoe per year on average in the 1990's, then by only 2 Mtoe in 2001 and 2002. Since then, despite a rebound in 2004, it had remained stable until the clear drop in 2009. Aggregated renewable thermal energy and energy recovered from waste continued their progression (+5.1%). The pace dipped slightly, but progress has been permanent since 2006 (+37% in 4 years). However, this group of sources still only accounts for 6.4 per cent of primary consumption. Stimulated by the rigours of the climate, gas beat all its records. However, after correction, its level was close to that around which it was fluctuating before the crisis, between 2002 and 2008. Primary electricity consumption (+2

    Host–guest interactions between the aromatic molecules benzene, toluene, aniline and nitrobenzene and the redox-active TCNQ-based metal–organic framework (MOF), Fe(TCNQ)(4,4'-bpy) (1) (TCNQ = 7,7,8,8-tetracyanoquinodimethane), have been found to modulate spontaneous magnetization behaviours at low temperatures. An analogous MOF, Mn(TCNQ)(4,4'-bpy) (2) with isotropic Mn(II) ions as well as the two-dimensional compound Fe(TCNQ)(DMF)2·2DMF (3·2DMF), were also prepared as models for studying the effects of single-ion magnetic anisotropy and structural distortion on spin canting. The results indicate guest-dependent long range magnetic ordering occurs at low temperatures, which correlates with the electrostatic and steric effects of the incorporated aromatic guests.

    This paper analyses the educational attainment of young first generation immigrants in Denmark who are children of the ‘guest workers’ who immigrated from Turkey, Pakistan and Ex-Yugoslavia in the late 1960s and early 1970s. Beside the traditional intergenerational transmission mechanism, we...... analyse potential immigrant-specific factors as language proficiency, attending mother-tongue courses and expectations concerning out or return migration from Denmark. The results show that intergenerational transmission effects are strong among ‘guest worker’ immigrants, especially among men. Other...... important factors are Danish language proficiency, age at first marriage and a number variables reflecting parents’ and own attitudes concerning education, marriage and family. However, the ‘guest worker’ immigrants are not a homogenous group. The analyses reveal large differences between Turkish, Pakistani...

    Host-guest complexation with various hydrophobic drugs has been used to enhance the solubility, permeability, and stability of guest drugs. Physical changes in hydrophobic drugs by complexation have been related to corresponding increases in the bioavailability of these drugs. Carbohydrates, including various derivatives of cyclodextrins, cyclosophoraoses, and some linear oligosaccharides, are generally used as host complexation agents in drug delivery systems. Many antibiotics with low bioavailability have some limitations to their clinical use due to their intrinsically poor aqueous solubility. Bioavailability enhancement is therefore an important step to achieve the desired concentration of antibiotics in the treatment of bacterial infections. Antibiotics encapsulated in a complexation-based drug delivery system will display improved antibacterial activity making it possible to reduce dosages and overcome the serious global problem of antibiotic resistance. Here, we review the present research trends in carbohydrate-based host-guest complexation of various hydrophobic antibiotics as an efficient delivery system to improve solubility, permeability, stability, and controlled release.

    This thesis is focused on the development of complex procedure with using commercially available sorbents to separate anthropogenic actinides 237 Np, 241 Am, 238 Pu and 239 , 240 Pu and their determination in the liquid radioactive wastes by using alpha spectrometry. Abilities of using commercially available sorbent AnaLig(R)Pu-02 gel from IBC Advanced Technologies, Inc. were tested, this product belongs to host-guest materials based on molecular recognition technology. This material is capable of selectively capturing actinides in oxidation state IV. To adjust the oxidation state of 238 Pu and 239 , 240 Pu was used NaNO 2 . Pu(IV) forms in the medium of nitric acid complexes, [Np(NO 3 ) 6 ] - , which are captured on the column. For the second monitored radionuclide, neptunium is typical valence V, Np(V) in the concentrated nitric acid produces strong complexes, [Np(NO 3 ) 6 ] - , which are capable of the sorption on the column of AnaLig(R)Pu-02 gel. The most common state of americium in aqueous solutions is III. Whereas in this oxidation state, americium do not form complexes in 8 mol·dm -3 nitric acid is the result of the flow-through. On the base of experimental obtained results, solution of 0.1 mol·dm -3 NH 4 I in 9 mol·dm -3 HCl was selected for elution of plutonium. Neptunium was eluted from the column using 9 mol·dm -3 of HCl with addition of 0.5 cm 3 TiCl 3 . Optimizing conditions for the separation procedure was performed by using model solution of radioactive waste which was prepared according to the chemical composition of radioactive concentrate from NPP Mochovce and NPP Bohunice. The effect of the concentration of Fe 3+ , the effect of the concentration of the HCl, the effect of the concentration of the solution of NH 4 I and the effect of the volume of this solution to the yields of 238 Pu were studied. And also was studied the effect of 9 mol·dm -3 of HCl and the effect of volume of 15 % TiCl 3 to the yields of 237 Np. Sorbent DGA(R) Resin from

    Chemical analyses of ancient organic compounds absorbed into the pottery fabrics of imported Etruscan amphoras (ca. 500-475 B.C.) and into a limestone pressing platform (ca. 425-400 B.C.) at the ancient coastal port site of Lattara in southern France provide the earliest biomolecular archaeological evidence for grape wine and viniculture from this country, which is crucial to the later history of wine in Europe and the rest of the world. The data support the hypothesis that export of wine by ship from Etruria in central Italy to southern Mediterranean France fueled an ever-growing market and interest in wine there, which, in turn, as evidenced by the winepress, led to transplantation of the Eurasian grapevine and the beginning of a Celtic industry in France. Herbal and pine resin additives to the Etruscan wine point to the medicinal role of wine in antiquity, as well as a means of preserving it during marine transport.

    2009-08-06

    The host-guest chemistry of dendrimer-drug complexes is investigated by NMR techniques, including (1)H NMR and 2D-NOESY studies. The effects of molecular properties of drug molecules (protonation ability and spatial steric hindrance of charged groups) and surface functionalities of dendrimers (positively charged amine groups and negatively charged carboxylate groups) on the host-guest interactions are discussed. Different interaction mechanisms between dendrimers and drug molecules are proposed on the basis of NMR results. Primary amine- and secondary amine-containing drugs preferentially bind to negatively charged dendrimers by strong electrostatic interactions, whereas tertiary amine and quaternary ammonium-containing drugs have weak binding ability with dendrimers due to relatively low protonation ability of the tertiary amine group and serious steric hindrance of the quaternary ammonium group. Positively charged drugs locate only on the surface of negatively charged dendrimers, whereas negatively charged drugs locate both on the surface and in the interior cavities of positively charged dendrimers. The host-guest chemistry of dendrimer-drug complexes is promising for the development of new drug delivery systems.

    In France, safety training for workers is compulsory under general legislation, supplemented in some cases by specific regulations on certain individual hazards. The radiation protection training for exposed workers is largely left to the initiative of the qualified officers, and there are regulations governing the training of the officers themselves. Qualified officers play a fundamental part in France in disseminating the radiation protection training and information which the regulations require them to have. It should be pointed out that qualification for the purposes of these regulations, implies having a clear grasp of the mechanisms involved rather than the acquisition of theoretical knowledge and requires a thorough understanding of the relevant legislation

    Low-temperature and high-pressure experiments were performed with filled ice Ih structure of methane hydrate under pressure and temperature conditions of 2.0 to 77.0 GPa and 30 to 300 K, respectively, using diamond anvil cells and a helium-refrigeration cryostat. Distinct changes in the axial ratios of the host framework were revealed by In-situ X-ray diffractometry. Splitting in the CH vibration modes of the guest methane molecules, which was previously explained by the orientational ordering of the guest molecules, was observed by Raman spectroscopy. The pressure and temperature conditions at the split of the vibration modes agreed well with those of the axial ratio changes. The results indicated that orientational ordering of the guest methane molecules from orientational disordered-state occurred at high pressures and low temperatures, and that this guest ordering led to the axial ratio changes in the host framework. Existing regions of the guest disordered-phase and the guest ordered-phase were roughly estimated by the X-ray data. In addition, above the pressure of the guest-ordered phase, another high pressure phase was developed at a low-temperature region. The deuterated-water host samples were also examined and isotopic effects on the guest ordering and phase changes were observed.

    Eddy covariance (EC) observations above the densely built-up center of Marseille during the Expérience sur site pour contraindre les modèles de pollution atmosphérique et de transport d'émissions (ESCOMPTE) summertime measurement campaign extend current understanding of surface atmosphere exchanges in cities. The instrument array presented opportunities to address issues of the representativeness of local-scale fluxes in urban settings. Separate EC systems operated at two levels, and a telescoping tower allowed the pair to be exposed at two different sets of heights. The flux and turbulence observations taken at the four heights, stratified by wind conditions (mistral wind and sea breeze), are used to address the partitioning of the surface energy balance in an area with large roughness elements. The turbulent sensible heat flux dominates in the daytime, although the storage heat flux is a significant term that peaks before solar noon. The turbulent latent heat flux is small but not negligible. Carbon dioxide fluxes show that this central city district is almost always a source, but the vegetation reduces the magnitude of the fluxes in the afternoon. The atmosphere in such a heavily developed area is rarely stable. The turbulence characteristics support the empirical functions proposed by M. Roth.

    Recently, circularly polarized luminescence (CPL)-active systems have become a very hot and interesting subject in chirality- and optics-related areas. The CPL-active systems are usually available by two approaches: covalently combining a luminescent centre to chiral motif or associating the guest of luminescent probe to a chiral host. However, all the chiral components in CPL materials were organic, although the luminescent components were alternatively organics or inorganics. Herein, the first totally inorganic CPL-active system by "luminescent guest-chiral host" strategy is proposed. Luminescent sub-10 nm lanthanide oxides (Eu 2 O 3 or Tb 2 O 3 ) nanoparticles (guests) were encapsulated into chiral non-helical SiO 2 nanofibres (host) through calcination of chiral SiO 2 hybrid nanofibres, trapping Eu 3+ (or Tb 3+ ). These lanthanide oxides display circular dichroism (CD) optical activity in the ultraviolet wavelength and CPL signals around at 615 nm for Eu 3+ and 545 nm for Tb 3+ . This work has implications for inorganic-based CPL-active systems by incorporation of various luminescent guests within chiral inorganic hosts. © 2018 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim.

    Full Text Available A lot of marketing experts in catering, restaurants especially, have recently been preoccupied by measuring the service quality. Business in competitive and turbulent surrounding requires that restaurants continually improve their products, which is based on guests specific demands and wishes. Comprehension of how consumers see catering offer and research on factors that determine consumers satisfaction are the key for achieving business aims. The aim of this study is an identification of key components of service qualities which restaurants and their influence on guests satisfaction offer. Measures of descriptive statistics, explorative factor and multiple regressive analysis were used in order to achieve the aims of the research. The facts were collected by using the survey. Results of the research highlight 3 key elements of the service quality that restaurants offer and those are: professionalism of personnel, understanding of guests, paying individual attention and meeting specific demands. The first two components include attributes that evince statistically important influence on guests satisfaction. Finds of conducted survey help managers and restaurateurs determine factors they will focus on during the making marketing strategy which will supply high level of consumers satisfaction on one side, and long-term profitability on the other side.

    Clathrate hydrates, or gas hydrates, are stabilized by van der Waals interaction between a guest molecule and a host framework. Because of their property, they are a potential resource in the exploitation of natural gas hydrates, as a material for the sequestration of carbon dioxide (CO{sub 2}), as a means of storage and transportation of natural gas, as well as hydrogen storage. Clathrate hydrate research can be divided into two categories that emphasize either macroscopic or microscopic approaches. However, these two approaches need to be closely linked for a better understanding of the structures and processes involving both natural phenomena and hydrates for industrial processes. Details on the molecular scale that concern the less usual properties of clathrate hydrates remain unknown. This paper presented the results of a study that reported on the existence of a critical guest concentration (CGC) and established the complete tuning pattern that occurred in the binary hydrates, including water-soluble hydrate formers (promoters) and water-insoluble guests. The paper presented the experimental procedures, including formation of the methane (CH{sub 4}) and tetrahydrofuran (THF) binary hydrate; a schematic diagram of the experimental apparatus; and formation of the CH{sub 4} and t-BuNH{sub 2} binary hydrate. Nuclear magnetic resonance (NMR) spectroscopic measurements and thermodynamic measurements were also presented. It was concluded that the CGC value appeared to primarily depend on the chemical nature of a liquid guest component participating in the binary hydrate formation. 10 refs., 2 tabs., 9 figs.

  6. Energy-cascade organic photovoltaic devices incorporating a host-guest architecture.

    2015-02-04

    In planar heterojunction organic photovoltaic devices (OPVs), broad spectral coverage can be realized by incorporating multiple molecular absorbers in an energy-cascade architecture. Here, this approach is combined with a host-guest donor layer architecture previously shown to optimize exciton transport for the fluorescent organic semiconductor boron subphthalocyanine chloride (SubPc) when diluted in an optically transparent host. In order to maximize the absorption efficiency, energy-cascade OPVs that utilize both photoactive host and guest donor materials are examined using the pairing of SubPc and boron subnaphthalocyanine chloride (SubNc), respectively. In a planar heterojunction architecture, excitons generated on the SubPc host rapidly energy transfer to the SubNc guest, where they may migrate toward the dissociating, donor-acceptor interface. Overall, the incorporation of a photoactive host leads to a 13% enhancement in the short-circuit current density and a 20% enhancement in the power conversion efficiency relative to an optimized host-guest OPV combining SubNc with a nonabsorbing host. This work underscores the potential for further design refinements in planar heterojunction OPVs and demonstrates progress toward the effective separation of functionality between constituent OPV materials.

    2002-03-13

    Urea inclusion compounds (UICs) have been used as tools to understand ferroelastic domain switching and molecular recognition during crystal growth. Although the vast majority of UICs contain helical arrangements of host H-bonds, those containing guests with the formula X(CH(2))(6)Y (X, Y = Br, Cl, CN, NC) adopt an alternative P2(1)/n packing mode in which the host molecules exist as stacked loops of urea hexamers. Such structures may be further separated into two classes, ones distorted away from hexagonal symmetry along [100] (Br(CH(2))(6)Br, Br(CH(2))(6)Cl, and Cl(CH(2))(6)Cl) and those distorted along [001] (e.g. NC(CH(2))(6)CN). In each of these systems, guests exist as equilibrium mixtures of gauche conformers whose populations control the direction and magnitude of the observed distortion. Such UICs are potentially ferroelastic, but the n-glide requires that domains are not related by a simple rotation-translation mechanism as in the helical systems. Ferroelastic (degenerate) domain reorientation would necessitate a large-scale reorganization of the urea framework and rupture of numerous H-bonds. Coupled with distortions of 2 to 10%, this mechanism-based barrier to domain switching has precluded observation of this phenomenon. To prepare ferroelastic UICs with minimal distortions from hexagonal symmetry, attempts were made to form solid solutions of UICs containing guests from the two classes. This failed, however: solid solution formation of the stacked loop form is usually possible within a series (e.g. with Cl(CH(2))(6)Cl and Br(CH(2))(6)Br), but not between series (e.g. Cl(CH(2))(6)Cl and NC(CH(2))(6)CN). Crystals of Cl(CH(2))(6)CN/urea, in which a single guest contains substituents from each class, are distorted along [001] by only 0.5% from hexagonal symmetry at 298 K and exhibit ferroelastic domain reorientation at high forces. At -66 degrees C, Cl(CH(2))(6)CN/urea undergoes a topotactic phase transition that is unexpectedly nontopochemical. The

  10. France under a microscope - Nuclear power in France

    International Nuclear Information System (INIS)

    2008-01-01

    The first French nuclear power plant was built in 1956, but it was only after the 1970's oil shock that nuclear power gained an important place in the French energy sector. Planning Act 2005-781 of 13 July 2005 laying down French energy policy orientations confirmed that nuclear energy was to remain the primary source of electricity supply in France. The Act also encourages diversification of sources of electricity production through renewable energies (wind power, biomass) and the security of electricity supply from oil, gas and coal. Nuclear energy accounted for 78.4% of electricity production in France in 2006. French nuclear capacity includes 58 pressurized water reactors (PWRs) that produced 450 billion nuclear kilowatt-hours (kWh) in 2006, i.e. 78.4% of total electricity production which is of 574 billion kWh. The lifetime of a third of currently operating nuclear plants will end in around 2020 and, with a view to the renewal of its nuclear capacity, France is about to deploy new-generation reactors that meet requirements in terms of production, environmental protection and enhanced nuclear safety. In April 2007, France started building a third-generation EPR reactor at Flamanville in the Manche Department. The EPR is to be operational by 2012. France is also devoting research programmes to fourth generation reactor technology with a view to those reactors being operational by 2040. There are a number of reasons for choosing nuclear power: it enables France to ensure its national energy independence (France imports less than 50% of its energy resources) and environmental protection (France is one of the European countries which emits the least greenhouse gases) at a stable and competitive price. Decree 2008-378 of 21 April 2008 instituted a council on nuclear policy presided by the President of the Republic. The council will define the broad lines of nuclear policy and monitor their implementation, particularly with regard to exports and international

    As revealed in previous empirical research, nurses describe their position in home-based nursing care (HBNC) as that of 'guests' in the patient's home. Such a description is problematic as 'guests' might not be considered to belong to the realm of professionalism. As Jacques Derrida's work on hospitality has received wide publicity, sparking theoretical and philosophical discussion about host and guest, the aim of this study was to explore how the concept 'guests' can be understood in the light of Derrida's philosophy of hospitality. The study revealed that (a) guest must be considered a binary concept; and (b) hospitality should be regarded as an exchange of giving and receiving between a host and a guest. The present study demonstrated that it is important to reflect on the meaning of the concepts used by nurses in HBNC. Further theoretical and empirical exploration of the concept 'hospitality' would be fruitful, i.e. what is patients' understanding of 'hospitality' and 'hostility' related to nurses' descriptions of themselves as 'guests' in the patient's home. © 2013 Blackwell Publishing Ltd.

  12. Observation of the energy transfer sequence in an organic host–guest system of a luminescent polymer and a phosphorescent molecule

    2014-01-01

    We used steady state optical spectroscopies such as photoluminescence and photoinduced absorption (PA), and magnetic-field PA (MPA) for studying the energy transfer dynamics in films and organic light emitting diodes (OLED) based on host–guest blends with different guest concentrations of the fluorescent polymer poly-[2-methoxy, 5-(2′-ethyl-hexyloxy)phenylene vinylene] (MEHPPV-host), and phosphorescent molecule PtII-tetraphenyltetrabenzoporphyrin [Pt(tpbp); guest]. We show that the energy transfer process between the excited states of the host polymer and guest molecule takes a ‘ping-pong’ type sequence, because the lowest guest triplet exciton energy, E T (guest), lies higher than that of the host, E T (host). Upon photon excitation the photogenerated singlet excitons in the host polymer chains first undergo a Förster resonant energy transfer process to the guest singlet manifold, which subsequently reaches E T (guest) by intersystem crossing. Because E T (guest)>E T (host) there is a subsequent Dexter type energy transfer from E T (guest) to E T (host). This energy transfer sequence has profound influence on the photoluminescence and electroluminescence emission spectra in both films and OLED devices based on the MEHPPV-Pt(tpbp) system. - Highlights: • We studied electroluminescence of OLEDs based on host–guest blends. • The emission efficiency decreases with the guest concentration. • We found a dominant Dexter energy transfer from the triplet(guest) to triplet(host). • Energy transfer occurs from the host to guest and back to the host again

  13. Recruiting Future Engineers Through Effective Guest Speaking In Elementary School Classrooms

    Energy Technology Data Exchange (ETDEWEB)

    Kevin Young

    2007-11-01

    In this paper, the author describes how engineers can increase the number of future engineers by volunteering as guest speakers in the elementary school classroom. The paper is divided into three main subjects. First, the importance of engineers speaking directly with young students is discussed. Next, several best practice techniques for speaking with young students are described. Finally, information on getting started as a guest speaker is presented, and a list of resources available to guest speakers is provided. The guest engineer speaking to an elementary school audience (ages 6-11) performs a critical role in encouraging young students to pursue a career in engineering. Often, he or she is the first engineer these students meet in person, providing a crucial first impression of the engineering career field and a positive visual image of what an engineer really looks like. A dynamic speaker presenting a well-delivered talk creates a lasting, positive impression on students, influencing their future decisions to pursue careers in engineering. By reaching these students early in life, the guest speaker will help dispel the many prevailing stereotypes about engineers which discourage so many students, especially young women, from considering this career. The guest speaker can ensure young students gain a positive first impression of engineers and the engineering career field by following some best practice techniques in preparing for and delivering their presentation. The author, an electrical engineer, developed these best practice techniques over the past 10 years while presenting over 350 talks on engineering subjects to elementary school students as a volunteer speaker with the U.S. Department of Energy, Idaho National Laboratory’s Speakers Bureau. Every engineer can make a meaningful contribution toward reversing the predicted shortfall of future engineers by volunteering to speak with young students at the elementary school level.

  14. Engineering responsive polymer building blocks with host-guest molecular recognition for functional applications.

    Hu, Jinming; Liu, Shiyong

    2014-07-15

    CONSPECTUS: All living organisms and soft matter are intrinsically responsive and adaptive to external stimuli. Inspired by this fact, tremendous effort aiming to emulate subtle responsive features exhibited by nature has spurred the invention of a diverse range of responsive polymeric materials. Conventional stimuli-responsive polymers are constructed via covalent bonds and can undergo reversible or irreversible changes in chemical structures, physicochemical properties, or both in response to a variety of external stimuli. They have been imparted with a variety of emerging applications including drug and gene delivery, optical sensing and imaging, diagnostics and therapies, smart coatings and textiles, and tissue engineering. On the other hand, in comparison with molecular chemistry held by covalent bonds, supramolecular chemistry built on weak and reversible noncovalent interactions has emerged as a powerful and versatile strategy for materials fabrication due to its facile accessibility, extraordinary reversibility and adaptivity, and potent applications in diverse fields. Typically involving more than one type of noncovalent interactions (e.g., hydrogen bonding, metal coordination, hydrophobic association, electrostatic interactions, van der Waals forces, and π-π stacking), host-guest recognition refers to the formation of supramolecular inclusion complexes between two or more entities connected together in a highly controlled and cooperative manner. The inherently reversible and adaptive nature of host-guest molecular recognition chemistry, stemming from multiple noncovalent interactions, has opened up a new platform to construct novel types of stimuli-responsive materials. The introduction of host-guest chemistry not only enriches the realm of responsive materials but also confers them with promising new applications. Most intriguingly, the integration of responsive polymer building blocks with host-guest recognition motifs will endow the former with

    Taccoen, L.B.C.

    1977-01-01

    The anti-nuclear movements in France are part of a broader movement which, following common usage, the author calls the Ecological Movement. In France, the movement can be divided into a fairly small politically oriented core, numerous and varied associations for the defence of the environment, and a number of consumer associations. The movement cannot be classified politically, which accounts for the attitude of the political parties - distrust of the ''ecologists'', but considerable interest in them as voters. Those with responsibility for power generation must explain to the population at large the energy problem and the importance of economic growth in raising wages and reducing unemployment. They must also explain why nuclear power generation is one of the safest technologies existing at present. (author)

  16. Coal: a revival for France?

    International Nuclear Information System (INIS)

    Brones, W.

    2007-01-01

    All energy consumption forecasts indicate a world production peak of fossil fuels around 2030 followed by a rapid decline. The oil peak should probably occur earlier. In this context the huge worldwide reserves of coal represent a fantastic opportunity to meet the world power demand which should double between 2002 and 2030 with in particular a huge growth in China and India. If promising alternate technologies (coal liquefaction..) exist which would allow to replace petroleum by coal, the main question remains the management of CO 2 . Capture and sequestration techniques are already implemented and tested and the search for new coal deposits is going on, in particular in France in the Nievre area. Economic studies about the profitability of coal exploitation in France stress on the socio-economical advantage that a revival of this activity would represent, in particular in terms of employment.

    With 41 nuclear power units operating and another 21 units under construction, France is serious about improving personnel training for the 3000 new employees each year. Electricite de France (EdF) takes a paternalistic approach to personnel training and to recruitment and advancement from within the organization. Courses in the training program range from one day to one year in length, and may take place either on or off the site. The author describes the training centers and schedule, but emphasizes the training is an ongoing process. Most instructors come from operating power stations. The courses use simulators to train operators in the use of fault analysis during an emergency. Computer-aided teaching systems are also widely used. 1 figure

    The finding that meningeal solitary fibrous tumors (SFTs) and meningeal hemangiopericytomas (HPCs) are both characterized by NAB2-STAT6 gene fusion has pushed their inclusion in the WHO 2016 Classification of tumors of the central nervous system (CNS) as different manifestations of the same entity. Given that the clinical behavior of the CNS SFT/HPC spectrum ranges from benign to malignant, it is presently unclear whether the grading criteria are still adequate. Here, we present the results of a study that analyzed the prognostic value of an updated version of the Marseille Grading System (MGS) in a retrospectively assembled cohort of 132 primary meningeal SFTs/HPCs with nuclear overexpression of STAT6. The median patient follow-up was 64 months (range 4-274 months); 73 cases (55%) were MGS I, 50 cases (38%) MGS II and 9 cases (7%) were MGS III. Progression-free survival (PFS) and disease-specific survival (DSS) were investigated using univariate analysis: the prognostic factors for PFS included MGS, extent of surgery, radiotherapy, chemotherapy and mitotic activity ≥5/10 high-power field (HPF). Moreover, MGS, radiotherapy, mitotic activity ≥5/10 HPF, and necrosis were the prognostic factors measured for DSS. In multivariate analysis, extent of surgery, mitotic activity ≥5/10 HPF, MGS I and MGS III were the independent prognostic factors measured for PFS while necrosis, MGS III and radiotherapy were the independent prognostic factors for DSS. In conclusion, our results show that assessing the malignancy risk of SFT/HPC should not rely on one single criterion like mitotic activity. Therefore, MGS is useful as it combines the value of different criteria. In particular, the combination of a high mitotic activity and necrosis (MGS III) indicates a particularly poor prognosis. © 2018 International Society of Neuropathology.

  2. Regional indexes for France. Methodology

    International Nuclear Information System (INIS)

    2006-01-01

    According to the U.S. Department of Energy, an estimated 25% of the GNP is affected by weather-related events. The variations in temperature - even small ones - can also have long-lasting effects on the operational results of a company. Among other, the Energy supply sector is sensitive to weather risks: a milder or harsher than usual winter leads to a decrease or increase of energy consumption. The price of electricity on power trading facilities like Powernext is especially sensitive to odd changes in temperatures. Powernext and Meteo-France (the French meteorological agency) have joined expertise in order to promote the use of weather indices in term of decision making or underlying of hedging tools to energy actors, end users from any other sector of activity and specialists of the weather risk hedging. The Powernext Weather indices are made from information collected by Meteo-France's main observation network according to the norms of international meteorology, in areas carefully selected. The gross data are submitted to a thorough review allowing the correction of abnormalities and the reconstitution of missing data. Each index is fashioned to take into account the economic activity in the various regions of the country as represented by each region's population. This demographic information represents a fair approximation of the weight of the regional economic activity. This document presents the calculation methodology of regional weather indexes for France. Each regional index covers an homogenous area in terms of temperature represented by the biggest city. Five reference cities are used to represent the 22 economical regions of France (Paris Orly, Lyon, Marignane, Bordeaux and Strasbourg). (J.S.)

  3. Jihadists’ Grievance Narratives against France

    2018-02-01

    Full Text Available France ranks first in the EU as a provider of foreign terrorist fighters in Syria and Iraq, and as the most-targeted European country in the context of the Syrian-Iraqi conflict. France has a longstanding history related to jihadism, correlated with multiple grievances from jihadist groups: it has been depicted as an enemy of Islam because of its foreign policy, its domestic policy towards religion, and, last but not least, its very essence. These grievances have been conveyed, like the baton of a relay race, from the first generations of North-African Islamist networks and the “elder brothers of jihad” to contemporary jihadists. The French jihadist media ecosystem has been instrumental in attracting a particularly large contemporary following. From the French perspective, a range of social, cultural, religious, economic, political, demographic drivers and identity factors converged to create a fertile ground for receptive radicals to emerge and break away from democratic values. Informed by these issues, this Policy Brief aims to identify avenues of further development for the French counter-terrorism strategic communication strategy. It concludes by stressing the need for this communication strategy to strive for positive, alternative messaging to re-create a continuum between individuals in the jihadist milieu and France as a nation state.

    The authors propose a prospective scenario: the newly elected French president decides of a 20-year program to give up nuclear energy production. First, the Fessenheim and Gravelines reactors are closed. The others are to be closed by 2035. Investments are decided for offshore wind energy production, methanation projects, housing thermal insulation. Employees of the nuclear energy sector are taken into account. The authors describe the situation in 2020: energy supply problems, 5 more years of lifetime awarded to some nuclear power stations, decision to build only positive energy buildings, mandatory housing renovation, job creation, decision to develop carbon capture and storage projects. In 2025: the dismantling of nuclear reactors is going on and its cost is assessed, always more electrical vehicles, drastic cost reduction for lithium batteries. In 2035: renewable energies represent the half of the energy mix, the dismantling activity is a success for Areva. In parallel, current figures are given for energy consumption per year and per person in France and Germany, for energy French exports and imports, for electricity cost associated with the different energy sources, for the energy mix in France, for the number of jobs in the nuclear sector. In an interview, a member of the CEA comments the Italian, German and Swiss decisions to give up nuclear energy, the possibilities of its replacement by renewable energies, and the challenges associated with such a decision in France

    In 2008, national electrical consumption reached 494.5 TWh, an increase of 2.9 % compared with 2007 (480.4 TWh). Adjusted for winter and summer climate contingencies and leap year, its evolution rate compared with 2007 is +1.3 % Consumption by business and private customers came to 198.0 TWh, an increase of 5.9 % compared with 2007 (187.0 TWh); consumption by Large-scale industry and SME/SMIs came to 263.0 TWh, an increase of 0.7 % compared with 2007 (261.3 TWh). Generation in France came to 549.1 TWh, as in 2006, an increase of 4.3 TWh or +0.8 % compared with 2007 (544.8 TWh). Hydro-electric generation reached 68.0 TWh, an increase of 7.5 % compared with 2007 (63.3 TWh). Renewable energy sources generation but hydro reached 9.7 TWh, an increase of 23.8 % compared with 2007 (7.8 TWh), mainly due to an increase of 37.5 % of wind energy (5.6 TWh in 2008 compared with 4.0 TWh in 2007). This progression is coherent with the increase of 48% of the installed capacity for wind generation. Nuclear generation came to 418.3 TWh in 2008, a decrease of 0.1 % compared with 2007 (418.6 TWh). Fossil thermal generation came to 53.1 TWh, a decrease of 3.5 % compared with 2007 (55.1 TWh). The heaviest load in terms of capacity reaches 92.4 GW during winter 2008/2009. Its evolution rate compared with 2007 is +3.8 % with a temperature lower by 2.2 deg. C. Since 2001, the heaviest load in winter has increased by 16% whereas the national electrical consumption has increased by 10%. The year 2008 is marked by the commissioning of the 400 kV line VIGY-MARLENHEIM. Besides, the underground circuits lengths grow by 118 km over the entire network. In terms of physical exchanges of electrical energy between France and the neighbouring countries France exported a net total of 48.0 TWh, a decrease of 15.4 % compared with 2007 (56.7 TWh). Contractual exchanges with foreign countries came to a cumulative value for exports and imports of 116.2 TWh, an increase of 5.1 % compared with 2007 (110.5 TWh

    The present report gives an overview of the batteries and accumulators market in France in 2011 based on the data reported through ADEME's Register of Batteries and accumulators. In 2001, the French Environmental Agency, known as ADEME, implemented a follow-up of the batteries and accumulators market, creating the Observatory of batteries and accumulators (B and A). In 2010, ADEME created the National Register of producers of Batteries and Accumulators in the context of the implementation of the order issued on November 18, 2009. This is one of the four enforcement orders for the decree 2009-1139 issued on September 22, 2009, concerning batteries and accumulators put on the market and the disposal of waste batteries and accumulators, and which transposes the EU-Directive 2006/66/CE into French law. This Register follows the former Observatory for batteries and accumulators. This Register aims to record the producers on French territory and to collect the B and A producers and recycling companies' annual reporting: the regulation indeed requires that all B and A producers and recycling companies report annually on the Register the quantities of batteries and accumulators they put on the market, collect and treat. Based on this data analysis, ADEME issues an annual report allowing both the follow-up of the batteries and accumulators market in France and communication regarding the achievement of the collection and recovery objectives set by EU regulation.

    According to the U.S. Department of Energy, an estimated 25% of the GNP is affected by weather-related events. The variations in temperature - even small ones - can also have long-lasting effects on the operational results of a company. Among other, the Energy supply sector is sensitive to weather risks: a milder or harsher than usual winter leads to a decrease or increase of energy consumption. The price of electricity on power trading facilities like Powernext is especially sensitive to odd changes in temperatures. Powernext and Meteo-France (the French meteorological agency) have joined expertise in order to promote the use of weather indices in term of decision making or underlying of hedging tools to energy actors, end users from any other sector of activity and specialists of the weather risk hedging. The Powernext Weather indices are made from information collected by Meteo-France's main observation network according to the norms of international meteorology, in areas carefully selected.

    We used steady state optical spectroscopies such as photoluminescence and photoinduced absorption (PA), and magnetic-field PA (MPA) for studying the energy transfer dynamics in films and organic light emitting diodes (OLED) based on host–guest blends with different guest concentrations of the fluorescent polymer poly-[2-methoxy, 5-(2′-ethyl-hexyloxy)phenylene vinylene] (MEHPPV-host), and phosphorescent molecule PtII-tetraphenyltetrabenzoporphyrin [Pt(tpbp); guest]. We show that the energy transfer process between the excited states of the host polymer and guest molecule takes a ‘ping-pong’ type sequence, because the lowest guest triplet exciton energy, E{sub T}(guest), lies higher than that of the host, E{sub T}(host). Upon photon excitation the photogenerated singlet excitons in the host polymer chains first undergo a Förster resonant energy transfer process to the guest singlet manifold, which subsequently reaches E{sub T}(guest) by intersystem crossing. Because E{sub T}(guest)>E{sub T}(host) there is a subsequent Dexter type energy transfer from E{sub T}(guest) to E{sub T}(host). This energy transfer sequence has profound influence on the photoluminescence and electroluminescence emission spectra in both films and OLED devices based on the MEHPPV-Pt(tpbp) system. - Highlights: • We studied electroluminescence of OLEDs based on host–guest blends. • The emission efficiency decreases with the guest concentration. • We found a dominant Dexter energy transfer from the triplet(guest) to triplet(host). • Energy transfer occurs from the host to guest and back to the host again.

    To explore why some hotels have implemented 100% smoke-free policies voluntarily, the perceived consequences of doing so, and media responses. Qualitative study of hotel management and quantitative content analysis of media coverage of smoke-free hotels. Hotels and media based in the United States. Eleven representatives of 5 independent and 4 chain hotels. Other data included 265 news items about smoke-free hotels. We conducted 30-minute semi-structured interviews with hotel representatives and analyzed the data using qualitative content analysis. We also searched 3 online news databases for news items about hotels in our study, and collaboratively coded retrieved items; we analyzed the content and slant of news items. Business considerations, including guest requests, competitor action, and cost savings, were the primary motivations for implementing 100% smoke-free guest-room policies. Health concerns played a minimal role. Hotels received positive feedback from customers and employees. Media coverage was favorable, emphasizing positive aspects of going smoke-free; the overall slant of news items was positive or neutral. However, few hotels marketed the change. Since hotel customers and employees are likely to experience long periods of smoke exposure and smoke-free hotels appear to be so well received, it may be timely to pursue policies making all hotels smoke-free.

    An elaborately designed pyridinium-functionalized octanuclear zinc(II) coordination container 1-Zn was prepared through the self-assembly of Zn 2+ , p-tert-butylsulfonylcalix[4]arene, and pyridinium-functionalized angular flexible dicarboxylate linker (H 2 BrL1). The structure was determined by a single-crystal X-ray diffractometer. 1-Zn displays highly sensitive and specific recognition to 2-picolylamine as revealed by drastic blueshifts of the absorption and emission spectra, ascribed to the decrease of intramolecular charge transfer (ICT) character of the container and the occurrence of intermolecular charge transfer between the host and guest molecules. The intramolecular charge transfer plays a key role in the modulation of the electronic properties and is tunable through endo-encapsulation of specific guest molecules. © 2018 Wiley-VCH Verlag GmbH & Co.

    To optimize the host–guest system of organic light emitting devices (OLEDs), it were performed simulations by doping a small molecule organic semiconductor (acting as host) with the transition organometallic complex known as Ir(ppy){sub 2}(acac) (acting as a guest). The simulation was carried out using simOLED with different mobility models: the Pool–Frenkel Model (PFM), the Extended Gaussian Disorder Model (EGDM) and Extended Correlated Disorder Model (ECDM), with the aim to determine the magnitude of some parameters like temperature, applied electric field, film thickness and charge carrier density that improve the electrical and optical properties of OLEDs with a more simplified structure like ITO/CBP/CBP:Ir(ppy){sub 2}(acac)/TPBi/LiF/Al.

  18. Knowledge of Deaths in Hotel Rooms Diminishes Perceived Value and Elicits Guest Aversion.

    Bering, Jesse M; Curtin, Emma R; Jong, Jonathan

    2017-01-01

    Guest deaths are an inevitable aspect of the hospitality industry. In Study 1, participants read a vignette in which the previous guest died of natural causes, suicide, or homicide. Those who learned of a death (a) saw the room as less valuable, (b) opted to stay in a more basic room in which no death occurred, despite both rooms being offered for free, and (c) anticipated feeling uneasy when imagining an overnight stay. In Study 2, we investigated the persistence of this bias. Perceived room value and anticipatory well-being can be expected to return to baseline levels only many years after the death event. Similar to "stigmatized properties" in real estate, these data confirm an irrational and recalcitrant cognitive bias surrounding consumers' views of death-affected hotel rooms.

    Guest-host polymer-dispersed liquid crystal (GHPDLC) films were prepared using a nematic liquid crystal, photo-curable polymer and dichroic dye (anthraquinone blue) by polymerization-induced phase separation (PIPS) technique. Non-ionic dichroic dye (1%, 2% and 4% wt./wt. ratio) was taken as guest in PDLC host. Polarizing microscopy shows that in the absence of electric field, liquid crystal (LC) droplets in polymer matrix mainly exhibit bipolar configuration, however, relatively at higher field, maltese-type crosses were observed. Our results show that approx1% dye-doped PDLC film shows better transmission and faster response times over pure polymer-dispersed nematic liquid crystal (PDNLC) and higher concentrated (2% and 4%) GHPDLC films.

    The dissociation kinetics of mixed gas hydrates that contain propane as a guest molecule have been investigated. The mixed gas hydrates used in this work were artificially prepared using the binary gas mixture of methane-propane and the ternary gas mixture of methane-ethane-propane. The crystal structures and the guest compositions of the mixed hydrates were clearly identified by using Raman spectroscopy and gas chromatography. The dissociation rates of the gas hydrates observed under several isothermal and isobaric conditions were discussed with an analytical model. The isobaric conditions were achieved by pressurizing with mixed gases using buffer cylinders, which had similar compositions to those of the initial gases used for synthesizing each hydrate sample. Interestingly, the calculated result agreed well with the experimentally observed results only when the composition of the vapor phase was assumed to be identical with that of the hydrate phase instead of the bulk (equilibrium) gas composition

  3. Toward Improved Force-Field Accuracy through Sensitivity Analysis of Host-Guest Binding Thermodynamics

    2015-01-01

    Improving the capability of atomistic computer models to predict the thermodynamics of noncovalent binding is critical for successful structure-based drug design, and the accuracy of such calculations remains limited by non-optimal force field parameters. Ideally, one would incorporate protein-ligand affinity data into force field parametrization, but this would be inefficient and costly. We now demonstrate that sensitivity analysis can be used to efficiently tune Lennard-Jones parameters of aqueous host-guest systems for increasingly accurate calculations of binding enthalpy. These results highlight the promise of a comprehensive use of calorimetric host-guest binding data, along with existing validation data sets, to improve force field parameters for the simulation of noncovalent binding, with the ultimate goal of making protein-ligand modeling more accurate and hence speeding drug discovery.

    Structure and dynamics of semicrystalline polymer films composed of syndiotactic polystyrene (sPS) and 2-butanone were examined through X-ray diffraction, polarized FTIR, and dielectric relaxation measurements. The X-ray and FTIR measurements revealed its crystal structure to be δ-clathrate containing 2-butanone molecules inside. The carbonyl group of 2-butanone in the crystal was found to orient preferentially parallel to the ac plane of the crystal through the polarized ATR FTIR measurements. Dielectric measurements were also conducted on these film samples to see only the relaxation dynamics of 2-butanone thanks to the high dielectric intensity of 2-butanone compared to sPS. Two relaxation modes denoted by slow and fast modes appeared. The former was assigned to the motion of 2-butanone molecules entrapped in the cavities of the crystalline (δ-form) and the latter to those in the amorphous region. We focused on the slow mode in order to elucidate the specific dynamics of the guest molecule confined in the crystalline region. The relaxation time of the slow mode was about 4 orders of magnitude longer than that of liquid 2-butanone. This suggests that the dynamics of guest molecules is highly restricted due to the high barrier to conformational and/or orientational change of the guest molecule in the cavity of δ-crystal. Furthermore, the dielectric intensity Δε of the slow mode was much smaller than the one calculated from that of bulk liquid 2-butanone and the guest concentration in the crystalline region (the intensity was only 10% of the estimated value from the bulk liquid data). This result also indicates that the free rotational motion of 2-butanone molecules is restricted inside the crystal. This will be consistently related to the weak uniplanar orientation of the carbonyl group of 2-butanone parallel to the ac plane revealed by the X-ray and polarized ATR FTIR measurements.

    Host-guest chemistry involves the complimentary binding between two molecules. Host molecules have been synthesized to bind negative, positive, and neutral molecules such as proteins and enzymes, and have been used as optical sensors, electrochemical sensors, supramolecular catalysts, and in the pharmaceutical industry as anti-cancer agents.1 The field of nanoscience has exploited guest-host interactions to create optical sensors with colloidal gold and Dip-Pen nanolithography technologies. Gold nanoparticles, have been functionalized with DNA, and have been developed as a selective colorimetric detection system, that upon binding turns the solution from a red to blue in color.2 Cyclotriveratrylene (CTV) 1 is a common supramolecular scaffold that has been previously employed in guest-host chemistry, and the construction of CTV involves the cyclic trimerization of veratryl alcohol via the veratryl cation.3 Due to the rigid bowl shaped structure of CTV, CTV has been shown to act as a host molecule for fullerene-C60.4 Lectin binding receptor proteins are a specific class of proteins found in bacteria, viruses, plants, and animals that can bind to complimentary carbohydrates. It is these lectins that are believed to be responsible for cell-cell interactions and the formation of biofilms in pathenogenic bacteria.5 P. aeruginosa is a pathenogenic bacterium, shown to have a high resistance to many antibiotics, which can form biofilms in human lung tissue, causing respiratory tract infections in patients with compromised immune systems. 5 I will exploit guest-host interactions to create synthetic supramolecular and carbohydrate receptor molecules to that will be of use as biological sensing devices via self-assembled monolayers on solid surfaces and nanoparticle technologies. *Please refer to dissertation for references/footnotes.

    The ESCOMPTE Campaign has been conducted over Southern France (Provence region including the Marseille, Aix and Toulon cities and the Fos-Berre industrial center) in June and July of 2001. In order to study the redistribution of the pollutants emitted by anthropic and biogenic emissions and their impact on the atmospheric chemistry, we used meso-scale modeling (RAMS model, paralleled version 4.3, coupled on line with chemical modules : MOCA2.2 (Poulet et al, 2002) including 29 gaseous species). The hourly high resolution emissions were obtained from ESCOMPTE database (Ponche et al, 2002). The model was coupled with the dry deposition scheme (Walmsley and Weseley,1996). In this particular case of complex circulation (sea breeze associated with topography), the processes involving peaks of pollution were strongly non linear, and the meso scale modeling coupled on line with chemistry module was an essential step for a realistic redistribution of chemical species. Two nested grids satisfactorily describe the synoptic dynamics and the sea breeze circulations. The ECMWF meteorological fields provide the initial and boundary conditions. Different events characterized by various meteorological situations were simulated. Meteorological fields retrieved by modeling, also Modeled ozone, NOx, CO and SO2 concentrations, were compared with balloons, lidars, aircrafts and surface stations measurements. The chemistry regimes were explained according to the distribution of plumes. The stratified layers were examined.

    Graphical abstract: - Highlights: • Different conformation of β-CD derivatives. • Enthalpy gain. • High binding ability. - Abstract: The molecular binding behaviors of two β-cyclodextrin (β-CD) derivatives bearing 1,2,3-triazole moieties, i.e. mono-6-deoxy-6-{4-(8-oxymethylquinolino)[1,2,3]triazolyl}-β-CD (1) and mono-6-deoxy-6-{4-(8-oxymethylnaphthol)[1,2,3]triazolyl}-β-CD (3), and their analogs without 1,2,3-triazole moieties, i.e. mono-6-deoxy-6-(8-oxymethylquinolino)-β-CD (2) and mono-6-deoxy-6-(8-oxymethylnaphthol)-β-CD (4) toward spherical guests (±)-borneol and (±)-camphor were investigated to elucidate how substituent moiety of host affects the binding abilities by 2D NMR as well as microcalorimetric titrations in aqueous phosphate buffer solution (pH 7.20) at 298.15 K. The binding modes of host–guest interactions obtained from 2D NMR displayed that host CDs without triazole moieties gave better induce-fit efficiency between hosts and guests, leading to stronger binding abilities. Thermodynamically, the inclusion complexation was driven by enthalpy with the stoichiometry of 1:1. Another factor contributed to the enhanced binding abilities was the enthalpy gain with the smaller entropy loss.

    Full Text Available In this study, the host-guest behavior of poly(amidoamine (PAMAM dendrimers bearing amine, hydroxyl, or carboxylate surface functionalities were investigated by paramagnetic NMR studies. 2,2,6,6-Tetramethylpiperidinyloxy (TEMPO derivatives were used as paramagnetic guest molecules. The results showed that TEMPO-COOH significantly broaden the ¹H NMR peaks of amine- and hydroxyl-terminated PAMAM dendrimers. In comparison, no paramagnetic relaxation enhancement (PRE was observed between TEMPO-NH₂, TEMPO-OH and the three types of PAMAM dendrimers. The PRE phenomenon observed is correlated with the encapsulation of TEMPO-COOH within dendrimer pockets. Protonation of the tertiary amine groups within PAMAM dendrimers plays an important role during this process. Interestingly, the absence of TEMPO-COOH encapsulation within carboxylate-terminated PAMAM dendrimer is observed due to the repulsion of TEMPO-COO- anion and anionic dendrimer surface. The combination of paramagnetic probes and ¹H NMR linewidth analysis can be used as a powerful tool in the analysis of dendrimer-based host-guest systems.

    1999-08-20

    A Missouri Court of Appeals judge reversed a $14.5 million judgement against [name removed] Inc., which had been held liable for the beating and sexual assault of a guest in its hotel. The guest, identified as [name removed], had requested an upgrade to a concierge room, to increase her safety, but the hotel did not fill her request. When [name removed] opened her hotel room door the next morning, an assailant attacked, beat and raped her. The assailant escaped hotel security, but was later apprehended. The initial case against [name removed] and the assailant resulted in a $22.5 million judgement for [name removed] Both parties appealed. [Name removed] prevailed in its argument that the initial trial judge misinstructed the jury, and that [name removed] was unable to show clear and convincing evidence that the hotel's willful or conscious disregard for guest safety caused the situation. However, the court ruled against [name removed] on the basis of [name removed]'s fear-of-AIDS claim, because of her exposure to the virus.

  13. Synthesis and Guest Recognition of Switchable Pt-Salphen Based Molecular Tweezers

    Full Text Available Molecular tweezers are artificial receptors that have an open cavity generated by two recognition units pre-organized by a spacer. Switchable molecular tweezers, using a stimuli-responsive spacer, are particularly appealing as prototypes of the molecular machines that combine mechanical motion and allosteric recognition properties. In this present study, the synthesis of switchable molecular tweezers composed of a central terpyridine unit substituted in 4,4″ positions by two Pt(II-salphen complexes is reported. The terpyridine ligand can be reversibly converted upon Zn(II coordination from a free ‘U’-shaped closed form to a coordinated ‘W’ open form. This new substitution pattern enables a reverse control of the mechanical motion compared to the previously reported 6,6″ substituted terpyridine-based tweezers. Guest binding studies with aromatic guests showed an intercalation of coronene in the cavity created by the Pt-salphen moieties in the closed conformation. The formation of 1:1 host-guest complex was investigated by a combination of NMR studies and DFT calculations.

    Signal transducer and activator of transcription factor 3 (STAT-3) is known to be overexpressed in cancer stem cells. Poor solubility and variable drug absorption are linked to low bioavailability and decreased efficacy. Many of the drugs regulating STAT-3 expression lack aqueous solubility; hence hindering efficient bioavailability. A theranostics nanoplatform based on luminescent carbon particles decorated with cucurbit[6]uril is introduced for enhancing the solubility of niclosamide, a STAT-3 inhibitor. The host-guest chemistry between cucurbit[6]uril and niclosamide makes the delivery of the hydrophobic drug feasible while carbon nanoparticles enhance cellular internalization. Extensive physicochemical characterizations confirm successful synthesis. Subsequently, the host-guest chemistry of niclosamide and cucurbit[6]uril is studied experimentally and computationally. In vitro assessments in human breast cancer cells indicate approximately twofold enhancement in IC 50 of drug. Fourier transform infrared and fluorescence imaging demonstrate efficient cellular internalization. Furthermore, the catalytic biodegradation of the nanoplatforms occur upon exposure to human myeloperoxidase in short time. In vivo studies on athymic mice with MCF-7 xenograft indicate the size of tumor in the treatment group is half of the controls after 40 d. Immunohistochemistry corroborates the downregulation of STAT-3 phosphorylation. Overall, the host-guest chemistry on nanocarbon acts as a novel arsenal for STAT-3 inhibition. © 2016 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

    The powerful host-guest chemistry of cucurbit[8]uril (CB[8]) was employed to obtain photoresponsive polyelectrolyte multilayer films for the reversible and photocontrolled binding and release of an organic guest molecule. For this purpose, we designed and synthesized a polyelectrolyte with azobenzene side groups. Then, CB[8] was associated with the azo side group to obtain a supramolecular host-guest complex that was further used as building block in order to prepare photoresponsive and CB[8]-containing polyelectrolyte multilayer films. Ultraviolet spectroscopy and a dissipative quartz crystal microbalance are employed to monitor the formation of the host-guest complex and the layer-by-layer self-assembly of the multilayer films, respectively. We demonstrate that the photoresponsive properties of the azo side groups are maintained before and after host-guest complexation with CB[8] in solution and within the multilayer films, respectively. A guest molecule was then specifically included as second binding partner into the CB[8]-containing multilayer films. Subsequently, the release of the guest was performed by UV light irradiation due to the trans-cis isomerization of the adjacent azo side groups. Re-isomerization of the azo side groups was achieved by VIS light irradiation and enabled the rebinding of the guest into CB[8]. Finally, we demonstrate that the photocontrolled binding and release within CB[8]-containing multilayer films can reliably and reversibly be performed over a period of more than 2 weeks with constant binding efficiency. Therefore, we expect such novel type of photosensitive films to have promising future applications in the field of stimuli-responsive nanomaterials.

    Electricite de France produces almost 80% of its electricity by means of standardized PWR nuclear power stations. Starting in 1986, therefore, a project known as the 'Lifetime Project' was developed, whose aim was initially to ensure that the lifetime defined at design stage (40 years in general) could be attained without major difficulty (follow up of the aging process). It then became apparent that it would be useful to know just how far it would be technically and economically possible to go. As a result, the project is now working towards increasing the lifetime of power stations. (author)

    Science.gov (United States)

    Tabuteau, Didier

    2012-06-01

    Health is a dual notion. It is individual, singular and intimate. It is also collective, statistical and political. The modern problematic of health relies upon a balance of complex relations between individual and collective acceptances of the notion. You can try to outline the evolutions and the main concepts through a quadruple approach: health and politics, health and its professionals, health and society and in the end, health and the State. The relationships between health and politics in France are affected by the historical delay of France in public health, namely because of a structural weakness of the administrative organization of public health. Nevertheless France developed a dense and well organized care system and a universal social protection against the disease. The creation of the health professions in France was marked by a historical opposition between the doctors and the state which led to a failure of hygienist medicine and a fundamental misunderstanding on health insurance. Medical domination led to the organization of a system based on professional dichotomy and the delegation of the regulation skills to the health care professionals. The role of health issues in the French society was deeply renewed by the development of the medical and epidemiological knowledge. This resulted in a new political responsibility in the management of health risks but also in the confirmation of the patients' rights and the role of their associations in the health systems operations and the piloting of public policies. In this environment, the state has recently and progressively confirmed its dominating role in the health sector. A public hospital service was created In the 60's and 70's, then in the 80's there were recurrent interventions in order to control health spendings and eventually in the 90's health safety devices were set up. More recently, a process of health policies institutionalization confirmed this evolution. In the future, health issues should

    The violence against persons in France are various, from those inflicted by society against human groups or individuals, from those, almost unrecognizable, occurring inside the families. It is an important public health problem and need population-based surveys to evaluate and to prevent it. The numerous publications about violence, and particularly about violence against women which have been recently published reflect the actual awareness. But they demonstrate also the diversity and the evolution of the policies which do not simplify the the ways to find solutions.

    In this study, similar to Hofmann type M(C 4 H 7 NH 2 ) 2 Ni(CN) 4 (M=Ni or Co) host and M(C 4 H 7 NH 2 ) 2 Ni(CN) 4 .nG (M=Ni or Co; G=benzene, 1,2-, 1,3-dichlorobenzene; n=the number of guest) hostguest compounds were obtained chemically. The infrared spectra of these compounds were recorded with FT-IR spectrometer in the spectroscopic region of 4000cm-1-400cm-1. From these spectra the vibrational wave numbers of ligand molecule, Ni(CN) 4 2 - ion and guest molecules were determined. The absorption and the liberation processes of the guest molecules in the host compounds were examined at room temperature by gravimetric method. Otherwise, it was seen that the molecular structure was supported by making instrumental analysis of host and some host-guest compounds. By analysing the structures of host and host-guest compounds were found to be similar to those of Hofmann type compounds, ligand molecule cyclobutylamine were coordinated to M metal atom from cyclobutylamine's nitrogen atom, the guest molecules were imprisoned in the structural cavities between the sheets

    Social inequalities in diet are attributed to sociocultural determinants, economic constraints, and unequal access to healthy food. Fruits and vegetables are lacking in the diets of disadvantaged populations. The objective was to test the hypothesis that, in poor neighborhoods, community gardeners will have larger supply of healthy food, especially fruit and vegetables, than non-gardeners. We examined community gardens from the perspective of production, economics and nutrition, and social and symbolic dimensions, through multidisciplinary investigations involving women with access to a community garden plot in a poor neighborhood of Marseille, France. Gardeners' monthly household food supplies (purchases and garden production) were analyzed and compared with those of women with a similar socio-economic profile living in the same neighborhoods, without access to a garden. Twenty-one gardeners participated. Only eleven of them harvested during the month of the study, and the amount they collected averaged 53 g of produce per household member per day. Whether they harvested or not, most gardeners gave preference to diversity, taste and healthiness of produce over quantity produced. Interviews revealed a value assigned to social, cultural and symbolic dimensions: pride in producing and cooking their own produce, related self-esteem, and sharing their produce at the meal table. The only significant difference between the food supplies of gardener and non-gardener households was seen for fruit and vegetables (369 vs. 211 g/d per person). This difference was due to larger purchases of fruit and vegetables, and not to higher quantities produced. In spite of the cross-sectional nature of our study and the small quantities harvested, our results suggest that having access to a community garden could encourage socio-economically disadvantaged women to adopt dietary practices that more closely meet dietary recommendations.

    Mycetomas are chronic sub-cutaneous tropical infections in which exogenous causative agents, fungal (eumycetes) or bacterial (actinomycetes), generate grains. The typical presentation is multi-fistulized pseudotumors. This disease, particularly eumycetoma, is difficult to treat. It is a major health problem in tropical and subtropical countries. In France, the disease is rare, but patients have access to a broader range of treatments. The authors had for objective to present the cases of mycetomas diagnosed in developed country and their management. A retrospective study was made on the clinical presentation and management of mycetomas from 1995 to 2011, in the Bobigny Avicenne teaching hospital. Six patient files were studied. The patients were men with a median age of 31 years (16-70). Five patients were from Sub Saharan Africa, one from Sri Lanka. The etiologies were one actinomycetoma and five eumycetomas. There was bone involvement in five cases. There was one atypical presentation: a primary intra-osseous mycetoma. Three patients were cured including two by surgical management and one by medical treatment (actinomycetoma). Antifungal therapy failed (four patients) in every case (voriconazole, itraconazole, ketoconazole, terbinafine, caspofungin). The results of this study made in a non-epidemic zone revealed that despite a typical clinical presentation, the diagnosis and management were delayed because this imported disease is rare in France. The patients received new broad-spectrum triazole and caspofungin, but none were cured with antifungal therapy alone. Copyright © 2013. Published by Elsevier SAS.

  17. Heterogeneity of environments associated with transmission of visceral leishmaniasis in South-Eastern France and implication for control strategies.

    Benoit Faucher

    Full Text Available BACKGROUND: Visceral leishmaniasis due to Leishmania infantum is currently spreading into new foci across Europe. Leishmania infantum transmission in the Old World was reported to be strongly associated with a few specific environments. Environmental changes due to global warming or human activity were therefore incriminated in the spread of the disease. However, comprehensive studies were lacking to reliably identify all the environments at risk and thereby optimize monitoring and control strategy. METHODOLOGY/FINDINGS: We exhaustively collected 328 cases of autochthonous visceral leishmaniasis from 1993 to 2009 in South-Eastern France. Leishmaniasis incidence decreased from 31 yearly cases between 1993 and 1997 to 12 yearly cases between 2005 and 2009 mostly because Leishmania/HIV coinfection were less frequent. No spread of human visceral leishmaniasis was observed in the studied region. Two major foci were identified, associated with opposite environments: whereas one involved semi-rural hillside environments partly made of mixed forests, the other involved urban and peri-urban areas in and around the region main town, Marseille. The two neighboring foci were related to differing environments despite similar vectors (P. perniciosus, canine reservoir, parasite (L. infantum zymodeme MON-1, and human host. CONCLUSIONS/SIGNIFICANCE: This unprecedented collection of cases highlighted the occurrence of protracted urban transmission of L. infantum in France, a worrisome finding as the disease is currently spreading in other areas around the Mediterranean. These results complete previous studies about more widespread canine leishmaniasis or human asymptomatic carriage. This first application of systematic geostatistical methods to European human visceral leishmaniasis demonstrated an unsuspected heterogeneity of environments associated with the transmission of the disease. These findings modify the current view of leishmaniasis epidemiology. They

The 2 major oil crisis (in 1973 and 1979) made public opinion abruptly aware of the urgent necessity for the diversification of energy supplying. Today the French production of electricity rests on nuclear energy, fossil energy and renewable energies (hydroelectricity). France is the first European country for nuclear energy (88 millions tons of oil equivalent in 1999) and for renewable energy (29 millions toe). The energy independence rate has sharply increased in 20 years from 26% in 1973 it reaches now 49%. France has developed an important capacity of fossil fuels storage about 10.5 milliards m 3 , it means that France can face a 30% decrease in its energy imports for a year without reducing its industrial output. Because of their energy choices Switzerland and France are the European countries the least sensible to price fluctuations of oil and gas. The doubling of oil price has implied a 0.32 francs rise of kWh cost in France and a 1.8 francs rise elsewhere in Europe. (A.C.)

    2014-01-01

    While recalling the five main objectives of the French bill project for energy transition, the author proposes some critical reflections. He notices that economic, political and financial means to reach the expected decrease of energy consumption are not sufficient. He notably comments the content of the various retained scenarios, discusses and explains the fact that there will always be a gap between the expected optimal energy efficiency and the obtained results: economic actors are not ready to make the required investments, France lacks of a culture of territorial energy governance, and a way of paying the produced carbon emissions is missing. He discusses the introduction of a carbon tax. He states that the Efficiency scenario seems difficult to be reached and briefly discusses the associated consequences. He finally outlines that the nuclear issue is not clearly addressed, either in the Ademe's scenario or by the bill project

  7. Sheep Feed and Scrapie, France

    2005-01-01

    Scrapie is a small ruminant, transmissible spongiform encephalopathy (TSE). Although in the past scrapie has not been considered a zoonosis, the emergence of bovine spongiform encephalopathy, transmissible to humans and experimentally to sheep, indicates that risk exists for small ruminant TSEs in humans. To identify the risk factors for introducing scrapie into sheep flocks, a case-control study was conducted in France from 1999 to 2000. Ninety-four case and 350 control flocks were matched by location and main breed. Three main hypotheses were tested: direct contact between flocks, indirect environmental contact, and foodborne risk. Statistical analysis was performed by using adjusted generalized linear models with the complementary log-log link function, considering flock size as an offset. A notable effect of using proprietary concentrates and milk replacers was observed. The risk was heterogeneous among feed factories. Contacts between flocks were not shown to be a risk factor.

  9. Wind energy in France: impossible?

    International Nuclear Information System (INIS)

    Marie-Josette, R.

    2005-01-01

    Since the end of 2004, the European Union is the first producer of wind energy in the world (34205 MW), far beyond the USA (6740 MW) and India (2110 MW). Three countries are in the pole position: Germany (16629 MW), Spain (8263 MW) and Denmark (3117 MW). On the other hand, despite a voluntarist policy, the other countries encounter administrative and local difficulties in the development of wind energy. This is the case with France which has the second biggest potential wind resource of Europe, behind the UK. The French situation is explained by its centralized energy system, by the priority given to nuclear power, by important wind variations, and by a bad image of wind turbines in general (aesthetic, environmental). This situation should change in the future with the scheduling of pluri-annual investments, with adapted tariffs and with improved administrative procedures. (J.S.)

    Solutions for radioactive waste management are already in existence and applied on an industrial scale for short-lived wastes. France has acquired an aknowledged expertise on the international level and several foreign contemporaries are interested in the relevant techniques developed. An intensive international cooperation has allowed to define bases for an underground deep repository for long-lived wastes. It is therefore important to choose a site which meets the expected storage conditions. This development work has been started in several countries in a similar way and which should be completed by the beginning of the next century. An 'open channel' with the public about this emotional topic can smooth the way for solutions by which mankind can master its technological challenges

    Full Text Available In the hotel industry, it is a well-known fact that, despite of quality and variety of services provided, there is a low probability that the guests will return. This research is focused on identifying the basic factors of the hotel offer, which could determine the influence on the correlation between the guests’ satisfaction and the probability of their return. The objective of the article is to explore the relationship between the guests’ satisfaction with the quality hotel services in total (including the tourist offer of the place and the probability of his return to the same destination. The questionnaire method was applied in the survey, and the data were analysed based on factor analysis. Thereafter, the model for forecasting the probability of the guests returning to the destination was established, by using the example of Montenegrin tourism. The model represents a defined framework for the guest’s decision-making process. It identifies two main characteristics of guest experiences: satisfaction and rated quality (of the destination’s overall hotel service and tourist offer. The same model evaluates the impact of the above factors on the probability of the guests’ returning to the same destination. The starting hypothesis was the existence of a high degree of correlation between the guests’ satisfaction (with the destination’s hotel services and tourist offer and the probability of returning to the selected Montenegrin destinations. The research confirmed the above-mentioned hypothesis. The results have revealed that there are significant differences in perceived quality, i.e. satisfaction between the target groups of Eastern and Western European tourists

    "This paper examines the problem of guest-worker migration from an economy populated by identical, utility-maximizing individuals with finite working lives. The decision to migrate, the rate of saving while abroad, as well as the length of a migrant's stay in the foreign country, are all viewed as part of a solution to an intertemporal optimization problem. In addition to studying the microeconomic aspects of temporary migration, the paper analyses the determinants of the equilibrium flow of migrants, the corresponding domestic wage, and the level of welfare enjoyed by a typical worker. Effects of an emigration tax are also investigated." excerpt

    Materials capable of sensing volatile guests at room temperature by an easily monitored set of outputs are of great appeal for development as chemical sensors of small volatile organics and toxic gases. Herein the dinuclear iron(II) complex, [Fe II 2 (L) 2 (CH 3 CN) 4 ](BF 4 ) 4 ⋅2 CH 3 CN (1) [L=4-(4-methylphenyl)-3-(3-pyridazinyl)-5-pyridyl-4H-1,2,4-triazole], is shown to undergo reversible single-crystal-to-single-crystal (SCSC) transformations upon exposure to vapors of different guests: 1 (MeCN)⇌2 (EtOH)→3 (H 2 O)⇌1 (MeCN). Whilst 1 and 2 remain dimetallic, SCSC to 3 involves conversion to a 1D polymeric chain (due to a change in L bridging mode), which, remarkably, can undergo SCSC de-polymerization, reforming dimetallic 1. Additionally, SC-XRD studies of two ordered transient forms, 1TF3 and 2TF3, confirm that guest exchange occurs by diffusion of the new guests into the non-porous lattices as the old guests leave. These reversible SCSC events also induce color and magnetic responses. Indeed dark red 1 is spin crossover active (T 1/2 ↓ 356 K; T 1/2 ↑ 369 K), whilst orange 2 and yellow 3 remain high spin. © 2016 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim.

    2-(Propylamino)acetamide of aniline (1a), and bis-2-(propylamino)acetamide of ortho- (1b) and para-(1c) phenylenediamine form host-guest complexes with CB[6], CB[7] and CB[8] as evidenced by the variations in the (1)H NMR spectroscopy chemical shifts and observation in MALDI-TOF-MS and ESI-MS of ions at the corresponding mass. Binding constants for the 1:1 complexes were estimated from fluorescence titrations and were in the range 10(5)-10(6)M(-1). Models based on molecular mechanics for these supramolecular complexes are provided. In spite of the different geometries arising from the ortho- or para-substitution, phenylenediamides form complexes of similar strength in which the hydrophobic alkyl chains are accommodated inside the host cavity. Formation of these host-guest complexes in the solid state was also achieved by modifying an aminopropyl silica with chloroacetanilides and preparing three silica having analogues of compounds 1a-c anchored to the solid particles. Titrations showed, however, that these solids can adsorb a large percentage of CBs by unselective interactions that are not related to the formation of inclusion complexes.

  11. Selective Organic and Organometallic Reactions in Water-Soluble Host-Guest Supramolecular Systems

    Energy Technology Data Exchange (ETDEWEB)

    Pluth, Michael D.; Raymond, Kenneth N.; Bergman, Robert G.

    2008-02-16

    Inspired by the efficiency and selectivity of enzymes, synthetic chemists have designed and prepared a wide range of host molecules that can bind smaller molecules with their cavities; this area has become known as 'supramolecular' or 'host-guest' chemistry. Pioneered by Lehn, Cram, Pedersen, and Breslow, and followed up by a large number of more recent investigators, it has been found that the chemical environment in each assembly - defined by the size, shape, charge, and functional group availability - greatly influences the guest-binding characteristics of these compounds. In contrast to the large number of binding studies that have been carried out in this area, the exploration of chemistry - especially catalytic chemistry - that can take place inside supramolecular host cavities is still in its infancy. For example, until the work described here was carried out, very few examples of organometallic reactivity inside supramolecular hosts were known, especially in water solution. For that reason, our group and the group directed by Kenneth Raymond decided to take advantage of our complementary expertise and attempt to carry out metal-mediated C-H bond activation reactions in water-soluble supramolecular systems. This article begins by providing background from the Raymond group in supramolecular coordination chemistry and the Bergman group in C-H bond activation. It goes on to report the results of our combined efforts in supramolecular C-H activation reactions, followed by extensions of this work into a wider range of intracavity transformations.

  12. Adsorption Mechanism of Inhibitor and Guest Molecules on the Surface of Gas Hydrates.

    Yagasaki, Takuma; Matsumoto, Masakazu; Tanaka, Hideki

    2015-09-23

    The adsorption of guest and kinetic inhibitor molecules on the surface of methane hydrate is investigated by using molecular dynamics simulations. We calculate the free energy profile for transferring a solute molecule from bulk water to the hydrate surface for various molecules. Spherical solutes with a diameter of ∼0.5 nm are significantly stabilized at the hydrate surface, whereas smaller and larger solutes exhibit lower adsorption affinity than the solutes of intermediate size. The range of the attractive force is subnanoscale, implying that this force has no effect on the macroscopic mass transfer of guest molecules in crystal growth processes of gas hydrates. We also examine the adsorption mechanism of a kinetic hydrate inhibitor. It is found that a monomer of the kinetic hydrate inhibitor is strongly adsorbed on the hydrate surface. However, the hydrogen bonding between the amide group of the inhibitor and water molecules on the hydrate surface, which was believed to be the driving force for the adsorption, makes no contribution to the adsorption affinity. The preferential adsorption of both the kinetic inhibitor and the spherical molecules to the surface is mainly due to the entropic stabilization arising from the presence of cavities at the hydrate surface. The dependence of surface affinity on the size of adsorbed molecules is also explained by this mechanism.

  13. The effect of host relaxation and dynamics on guest molecule dynamics in H2/tetrahydrofuranhydrate.

    Peterson, Vanessa K; Shoko, Elvis; Kearley, Gordon J

    2011-01-01

    We use ab initio molecular dynamics simulations to obtain classically the effects of H2O cage motions on the potential-energy surface (PES) of encapsulated H2 in the H2/tetrahydrofuran-hydrate system. The significant differences between the PES for the H2 in rigid and flexible cages that we find will influence calculation of the quantum dynamics of the H2. Part of these differences arises from the relaxation of the H2O cage around the classical H2, with a second part arising from the coupling of both translational and rotational motions of H2 with the H20 cage. We find that isotopic substitution of 2H for 1H of the H2O cage affects the coupling, which has implications for experiments that require the use of 2H2O, including inelastic neutron scattering that uses 2H2O cages in order to focus on the H2 guest dynamics. Overall, this work emphasizes the importance of taking into account cage dynamics in any approach used to understand the dynamics of H2 guests in porous framework materials.

    Thermoresponsive water-soluble polymers are of great importance since they typically show a lower critical solution temperature (LCST) in aqueous media. In this research, the LCST change in broad temperature ranges of copolymers composed of natural glycyrrhetinic acid (GA)-based methacrylate and N,N'-dimethylacrylamides (DMAs) was investigated as a function of the concentration and the content of GA pendants. By complexation of GA pendants with β-cyclodextrin (β-CD), a side-chain polypseudorotaxane was obtained, which exhibited a significant increase in the LCST of copolymers. Moreover, the precisely reversible control of the LCST behavior was realized through adding a competing guest molecule, sodium 1-admantylcarboxylate. This work illustrates a simple and effective approach to endow water-soluble polymers with broad temperature tunability and helps us further understand the effect of a biocompatible host-guest complementary β-CD/GA pair on the thermoresponsive process. © 2017 Wiley-VCH Verlag GmbH & Co.

    We developed dendritic caged molecular glues ( Caged Glue-R) as tags for nucleus-targeted drug delivery, whose multiple guanidinium ion (Gu + ) pendants are protected by an anionic photocleavable unit (butyrate-substituted nitroveratryloxycarbonyl; BA NVOC). Negatively charged Caged Glue-R hardly binds to anionic biomolecules because of their electrostatic repulsion. However, upon exposure of Caged Glue-R to UV light or near-infrared (NIR) light, the BA NVOC groups of Caged Glue-R are rapidly detached to yield an uncaged molecular glue ( Uncaged Glue-R) that carries multiple Gu + pendants. Because Gu + forms a salt bridge with PO 4 - , Uncaged Glue-R tightly adheres to anionic biomolecules such as DNA and phospholipids in cell membranes by a multivalent salt-bridge formation. When tagged with Caged Glue-R, guests can be taken up into living cells via endocytosis and hide in endosomes. However, when the Caged Glue-R tag is photochemically uncaged to form Uncaged Glue-R, the guests escape from the endosome and migrate into the cytoplasm followed by the cell nucleus. We demonstrated that quantum dots (QDs) tagged with Caged Glue-R can be delivered efficiently to cell nuclei eventually by irradiation with light.

    A dozen of homoditopic cations, possessing different spacer lengths and rigidities, as well as sizes, shapes, and charges of terminal groups, were synthesized as candidate gemini guests for the complexation of p-sulfonatocalix[4]arenes (SC4A). The 12 gemini guests are divided into five species according to the different terminal groups: imidazolium (G1-G3), pyridinium (G4-G6), quinolinium (G7), viologen (G8-G11), and 1,4-diazabicyclo[2.2.2]octane (DBO, G12). Their binding structures and stoichiometries with SC4A were examined by NMR spectroscopy, which is helpful to construct diverse highly ordered assemblies. The obtained results show that the length of the linkers, as well as the charge numbers on the end groups have a pronounced effect on the binding stoichiometry, whereas the size and shape of the terminal groups have no significant influence. Furthermore, both the stability constants and thermodynamic parameters of SC4A with the terminal subunits were determined by the isothermal titration calorimetry experiments, which are valuable to understand the binding behavior, giving quantitatively deep insight.

    A sensitive electrochemical aptasensor for thrombin detection is presented based on the host-guest recognition technique. In this sensing protocol, a 15 based thrombin aptamer (ab. TBA) was dually labeled with a thiol at its 3' end and a 4-((4-(dimethylamino)phenyl)azo) benzoic acid (dabcyl) at its 5' end, respectively, which was previously immobilized on one Au electrode surface by AuS bond and used as the thrombin probe during the protein sensing procedure. One special electrochemical marker was prepared by modifying CdS nanoparticle with β-cyclodextrins (ab. CdS-CDs), which employed as electrochemical signal provider and would conjunct with the thrombin probe modified electrode through the host-guest recognition of CDs to dabcyl. In the absence of thrombin, the probe adopted linear structure to conjunct with CdS-CDs. In present of thrombin, the TBA bond with thrombin and transformed into its special G-quarter structure, which forced CdS-CDs into the solution. Therefore, the target-TBA binding event can be sensitively transduced via detecting the electrochemical oxidation current signal of Cd of CdS nanoparticles in the solution. Using this method, as low as 4.6 pM thrombin had been detected. Copyright © 2012 Elsevier B.V. All rights reserved.

    1988-01-01

    French PWR power plant design relies basically on a deterministic approach. Nevertheless, an overall safety objective was issued in 1977 by the safety authority which set an upper probability limit for having unacceptable consequences; this resulted, in particular, in the elaboration of the ''H'' procedures, aimed at reducing significantly the risk of core uncovery subsequent to the loss of redunbant safety-related systems. The U1 symptom-oriented procedure, based on the nuclear steam supply system ''cooling states'', was introduced later, in order to prevent core melting in situations where the operating crew was confused by multiple failures and/or inappropriate previous actions. In the event that a core-melt should occur, the ultimate procedures U2, U4 and U5 - the latter providing a venting of the containment through a filtration system - should enable the radioactive releases to be limited to characteristics compatible with the feasibility of the off-site emergency plans. Such emergency management procedures necessitate a significant study effort in order to be elaborated and qualified; this also presupposes that an adequate level of scientific knowledge has been gained as regards the response of specific components of a PWR under beyond-design conditions. The purpose of severe accident research in France is to attain a level of basic knowledge such that emergency procedures may be conceived and ultimately tested

    2014-07-01

    As in 2012, activity in France increased slightly (+0.3%), thanks to an upturn in the second half. Fossil energy prices on the international markets took a downward turn in 2013 under the influence of the morose world economic climate, dropping sharply for oil and coal and rising, but at a slowed rate, for gas. Quoted prices nonetheless remained high: the Brent price remained well above US$100/barrel and steam coal above US$ 80/ton. Conversely, the price of natural gas took an upward path three years ago in continental Europe. Electricity prices dropped on the European markets, notably as a result of strong production of renewable energy in Germany and Spain. Energy prices in France continued to increase but at a slowed rate and more slowly than the prices for goods and services as a whole for the first time in 10 years. Prices for oil products saw a downturn, something which had not happened since 2009 but gas and electricity prices rose sharply. French households' average gasoline and diesel oil expenditure was euro 60 less in 2013 than in 2012, due almost entirely to the price drop. Spending on energy for household use increased by euro 100 under the combined effect of price increase and greater heating needs. French people's expenditure for energy represented 6.2% of their effective consumption. 2013 was characterised by a colder first half which induced an additional need for heating of 3.1 Mtoe in 2013 in relation to the previous year. The physical foreign trade gap, structurally biased towards imports, accordingly widened slightly in 2013 to 124 Mtoe, as a result of the refined oil products, and additional purchasing of coal made necessary by greater use of thermal power plants. The effect of decreasing international energy prices outweighed the physical flows: France's energy bill reduced by 4.6% in relation to the record 2012, reaching euro 66 billion. The oil bill was therefore significantly reduced as a result of the dual decrease in volume and price

  3. Post-mining in France

    2007-01-01

    This plentifully illustrated book aims at showing how new equilibria are building up during the transition between mining activity and post-mining, and at stressing on the necessity to keep up the cultural elements, the competencies and knowledge of mining works. The first chapter - mine and men - shows the importance of mineral substances in the objects of the everyday life, illustrates the importance of the mining tradition in France and describes the technical and administrative organisation of the end of the mining activity (works, rehabilitation, regulation, monitoring..). Chapter two - exploitation methods - presents the surface and underground facilities and their impact on the environment (extraction machines, workshops, ore processing plants, decantation ponds..). The third chapter deals with the rehabilitation and monitoring aspects: impact of mining activity stoppage on underground and surface waters, land stability, soils cleansing.. The last chapter summarizes the history of French mining region by region: Nord-Pas-de-Calais, Lorraine-Alsace, Massif central, Bretagne-Normandie, Provence-Alpes-Cote d'Azur and Pyrenees

    This report first gives a description of the world economic context in 2007 (GDP evolutions of several countries), and of the French macro-economic context in 2007 (GDP, goods production, demographic, household consumption, and trade evolutions). It comments the evolution of international oil product prices and of other energy prices (gas, coal) during the same year, and since 1980, and evokes other factors influencing the French energy bill (money market, climate). It briefly comments the evolution of the total primary energy consumption from 1973 to 2007. It describes the evolution of the national energy production, globally and for each energy source (coal, oil, natural gas, nuclear, hydro, wind, photovoltaic, renewable energies and wastes), indicating the energy independence rate for each of them, as well as the import origins. Energy consumption is then analysed in the same way, i.e., globally and for each energy source, and also by economic sectors (non-energetic uses, industry, housing and office buildings, agriculture, transports, electricity production). Some comments are made on the opening of the electricity market in France. The evolutions of the energy intensity and of carbon emissions related to energy consumption are finally discussed

    2013-07-01

    Economic activity in France stagnated in 2012. Energy prices continued to increase globally, sweeping along with them the prices of energy products imported into France, notably oil products and natural gas. In addition, the difference in temperatures between 2011 and 2012 created an additional energy need for 5.7 million tons oil equivalent (Mtoe) in 2012 in relation to the previous year. The volume of imports of refined oil products and coal increased to meet the additional needs of thermal power stations. The physical trade deficit thus increased for refined oil products (+29%) and for coal (+7%). In parallel, exports of electricity decreased. Nonetheless, the overall physical trade deficit decreased in 2012 (-1.5%). However, this apparent improvement was actually due to difficulties in the refining sector, resulting in a 12% decrease in crude oil imports. Increased imported energy prices and additional needs therefore explain the new peak in France's energy bill, which reached almost euro 69 billion, an increase of more than euro 7 billion in relation to 2011. National primary energy production settled back in 2012 at a little over 136 Mtoe, a decrease of 1.2% in relation to the record reached in 2011. This can be attributed almost entirely to the nuclear power sector which reduced production by more than 4 Mtoe as a result of decreased availability of nuclear power plants. National production of fossil energies, already marginal, continued to decline. Conversely, all of the renewable sources saw an upturn, after a year in 2011 marked by severe contrasts. After reaching a historical low in 2011, hydropower production increased by 25% as a result of the end of the period of drought. Installations continued to increase, with wind-generated and photovoltaic electricity and energy from renewable thermal sources and from waste all increasing their production in 2012. In all, the renewable energy sectors combined produced around 4 Mtoe more than in 2011. In 2012

  7. France energy status for 2011

    International Nuclear Information System (INIS)

    2012-07-01

    2001 was marked by a lifeless global economic context: growth in output, and especially in world trade, slowed sharply. The euro zone was particularly affected. In a tense geopolitical context, especially in the Middle East, international prices of raw materials rose sharply in 2011, in particular oil prices. This affected France's energy bill which, at euro 61.4 billion, increased by almost one-third and accounted for 88% of the country's trade deficit. It thus represents 3.1% of GDP, compared with just 1% in the 1990's. The bill for oil alone is now more than euro 50 billion. The impact could have been even greater if 2011 had not been the warmest year on record since 1900, with an average annual temperature 1.3 deg. C above the reference (1981-2010). As a result, energy needs for heating were much lower than average. The physical trade deficit decreased by 4%, as imports of gas and coal decreased. In terms of consumption, 6.6 million tonnes oil equivalent (Mtoe) were saved. Corrected for climate variations, total primary energy consumption continued its rise in 2011 (+0.8%) after the dip registered in 2009, a consequence of the economic crisis. It thus exceeded 266 Mtoe, but still remains below pre-crisis levels. In spite of lower growth than in the previous year (+ 3.6% against + 4.5% in 2010), consumption of thermal energy from renewable sources and energy recovered from waste showed the strongest increase in 2011. However, at 17.1 Mtoe, this still represents only 6.4% of total primary energy consumption. After two years of reduction, oil showed an upturn (+ 2 %). Primary electricity, also on the rise, consolidated its share of total primary consumption (almost 44%). Conversely, coal dropped by 14 % and its share in primary consumption has been quartered since the 1970's, at less than 4%. The structure of France's primary energy mix has thus stabilised since the mid 2000's. According to European directive indicators, and contrary to the situation in 2010

    This accounting document has been elaborated in compliance with standards defined by the European Union, the International Agency of Energy, and the United Nations. It gives a global overview of the supply and usage chain for each energy source (coal, oil, gas, electricity, thermal renewable energies and wastes). It also gives data related to energy efficiency, supply dependence on other countries, and carbon dioxide emissions. A first part presents the economic and climatic context for 2015: slow world economic growth and an oil market always in surplus, GDP growth at a higher rate, the third hottest year since 1900 with rainfall deficit and sunshine higher than normal. The second part analyses the weight of energy in the French economy: evolutions of energy and oil markets, decrease of energy bill, stronger decrease of oil product prices, higher energy expenses and lower fuel expenses for households. The third part analyses France's energy supply: slight increase of primary production, further decrease of coal imports, recovery of crude oil imports but decrease of refined product trade deficit, moderate increase of natural gas imports, moderate increase of some renewable productions (biomass, wastes, thermal solar, geothermal, heat pumps), slight increase of electricity production with increased use of natural gas. The fourth part analyses quantities and forms of consumed energy: globally, for coal, oil, gas, biomass, wastes, thermal solar, geothermal and heat pumps, and electricity. The fifth part analyses usages and sectors of energy consumption: global final energy, and case of housing and office building, transports, industry, agriculture and fishery. The sixth part proposes an assessment for overseas territories, globally and for the different energy sources. The seventh part discusses other energy-related issues: evolution of energy intensity, of CO_2 emissions due to energy combustion, co-generated heat and heat networks.

    Full Text Available The effect of polyphosphate (polyP microparticles on wound healing was tested both in vitro and in a mice model in vivo. Two approaches were used: pure salts of polyphosphate, fabricated as amorphous microparticles (MPs, consisting of calcium and magnesium salts of polyP, “Ca–polyp-MPs” and “Mg–polyp-MPs”, and host–guest composite particles, prepared from amorphous collagen (host and polyphosphate (guest, termed “col/polyp-MPs”. Animal experiments with polyP on healing of excisional wounds were performed using both normal mice and diabetic mice. After a healing period of 7 days “Ca–polyp-MP” significantly improved re-epithelialization in normal mice from 31% (control to 72% (polyP microparticle-treated. Importantly, in diabetic mice, particularly the host–guest particles “col/polyp-MP”, increased the rate of re-epithelialization to ≈40% (control, 23%. In addition, those particles increased the expression of COL-I and COL-III as well as the expression the α-smooth muscle actin and the plasminogen activator inhibitor-1. We propose that “Ca–polyp-MPs”, and particularly the host–guest “col/polyp-MPs” are useful for topical treatment of wounds.

    In the French Mediterranean basin the large city of Marseille and its industrialized suburbs (oil plants in the Fos-Berre area) are major pollutant sources that cause frequent and hazardous pollution episodes, especially in summer when intense solar heating enhances the photochemical activity and when the sea breeze circulation redistributes pollutants farther north in the countryside. This paper summarizes the findings of 5 years of research on the sea breeze in southern France and related mesoscale transport and dilution of pollutants within the Field Experiment to Constraint Models of Atmospheric Pollution and Emissions Transport (ESCOMPTE) program held in June and July 2001. This paper provides an overview of the experimental and numerical challenges identified before the ESCOMPTE field experiment and summarizes the key findings made in observation, simulation, and theory. We specifically address the role of large-scale atmospheric circulation to local ozone vertical distribution and the mesoscale processes driving horizontal advection of pollutants and vertical transport and mixing via entrainment at the top of the sea breeze or at the front and venting along the sloped terrain. The crucial importance of the interactions between processes of various spatial and temporal scales is thus highlighted. The advances in numerical modeling and forecasting of sea breeze events and ozone pollution episodes in southern France are also underlined. Finally, we conclude and point out some open research questions needing further investigation.

  3. Regard communautaire sur le parcours social et la sexualité des femmes sénégalaises « solitaires » à Marseille

    Full Text Available À travers la décision d’émigrer « en solitaire », à savoir non accompagnées par un homme de la famille, les femmes réalisent un parcours individuel selon des choix personnels, ce qui leur permet d’exercer aussi un meilleur contrôle sur leur corps. Elles bénéficient ainsi d’une plus grande autonomie sexuelle, qu’elles peuvent décider d’exploiter comme une source de revenus complémentaire à leur travail dans le secteur du commerce. Mais, de cette façon, elles s’exposent aussi aux dynamiques de catégorisation et d’étiquetage, voire de marginalisation, qui se mettent à l’œuvre dans la communauté migrante par rapport aux femmes « seules ». En effet, la remise en cause des principes traditionnels de l’échange économico-sexuel impliquée par ce choix de vie autonome ébranle en profondeur les règles qui assurent la reproduction de la communauté dans son ensemble et se trouve par conséquent critiquée et contrecarrée tant par les hommes que par les femmes de la communauté immigrée. Ainsi, la censure sur la conduite de ces femmes seules semble s’exercer indépendamment de la connaissance de leurs pratiques réelles et s’exprimer de manière d’autant plus virulente que l’on se trouve en migration, un contexte dans lequel les femmes occupent une place fondamentale dans les stratégies de reproduction, biologique et sociale, des groupes sociaux.Community perspective on the social route and the sexuality of « lonesome » Senegalese women in MarseilleThrough the decision to emigrate « alone », that is, unaccompanied by a male relative, women are marking out an individual path on the basis of personal choices that enables them to exercise more control over their bodies.

    The interactions between a host, water-soluble corona[n]arene (S6-CAP), and a series of guests, bisquaternary ammonium derivatives (CnDAs), in water, were investigated. The host and guest can form 1:1 host-guest complex. Their binding constants decrease as the alkyl length of CnDAs increases, which can be tunable ranging from 10 3 to 10 6 M -1 . The binding processes are mainly entropy-driven, while the enthalpy changes also play an important role in enhancing the host-guest interactions. In addition, a supra-amphiphile was fabricated with S6-CAP and a normal surfactant bearing bisquaternary ammonium (C4R). The S6-CAP·C4R complex forms micellar aggregates in water, and the system possesses better assembling activity and dilution stability than its building block C4R. This study enriches the families of supra-amphiphiles with a new architecture, and employing such a supra-amphiphile in biofunctional materials is highly anticipated.

  9. Host-guest interaction of styrene and ethylbenzene in MIL-53 studied by solid-state NMR.

    Li, Shenhui; Li, Jing; Tang, Jing; Deng, Feng

    Solid-state NMR was utilized to explore the host-guest interaction between adsorbate and adsorbent at atomic level to understand the separation mechanism of styrene (St) and ethylbenzene (EB) in MIL-53(Al). 13 C- 27 Al double-resonance NMR experiments revealed that the host-guest interaction between St and MIL-53 was much stronger than that of EB adsorption. In addition, 13 C DIPSHIFT experiments suggested that the adsorbed St was less mobile than EB confined inside the MIL-53 pore. Furthermore, the host-guest interaction model between St, EB and MIL-53 was established on the basis of the spatial proximities information extracted from 2D 1 H- 1 H homo-nuclear correlation NMR experiments. According to the experimental observation from solid-state NMR, it was found that the presence of π-π interaction between St and MIL-53 resulted in the stronger host-guest interaction and less mobility of St. This work provides direct experimental evidence for understanding the separation mechanism of St and EB using MIL-53 as an adsorbent.

    2004-07-01

    Variable temperature {sup 2}H NMR investigations have been carried out to study the molecular behavior of perdeuterated benzene and pyridine in the inclusion compound with tris-(1,2-dioxyphenyl)-cyclotriphosphazene. Here, a comprehensive variable temperature {sup 2}H NMR study is presented comprising line shape studies and relaxation experiments. The experimental data clearly indicate the presence of highly mobile guest species. Sample cooling gives rise to characteristic line shape effects that can be attributed to a slow-down of the rotational motion. Additional {sup 2}H NMR measurements were performed on the plastic crystal 1,4-diazabicyclo[2,2,2]octane where highly mobile species were observed. A quantitative analysis of the experimental data is achieved by appropriate computer simulations taking into account various molecular motions for each studied system. The analysis of these theoretical data give rise to the kinetic parameters that are in the order of related systems. (orig.)

    It was found that various organic materials are attracted into urea canal by hexanediol diacrylate (HDDA) and long chain compounds. This means that materials which does not form complex by itself are induced in canal by HDDA and long chain compounds. To include with stability perfumes, insecticides, attractants and repellents in urea canal, leaf alcohol was used as a model compound for guest molecules in the canal. The leaf alcohol from the canal released gradually over many days and the release was inhibited for 15 days by long chain compounds and for 30 days by polymerized HDDA after irradiation. After releasing, the leaf alcohol in the canal remained 25 % stable for long chain compounds and 40 % for polymerized HDDA. The dose required for stabilization of leaf alcohol in the urea canal by canal polymerization of HDDA was 30 kGy. (author)

    The formation of supramolecular host-guest complexes is a very useful and widely employed tool in chemistry. However, supramolecular chemistry in non-conventional solvents such as supercritical carbon dioxide (scCO2 ), one of the most promising sustainable solvents, is still in its infancy. In this work, we explored a successful route to the development of green processes in supercritical CO2 by combining a theoretical approach with experiments. We were able to synthesize and characterize an inclusion complex between a polar aromatic molecule (benzoic acid) and peracetylated-β-cyclodextrin, which is soluble in the supercritical medium. This finding opens the way to wide, environmental friendly, applications of scCO2 in many areas of chemistry, including supramolecular synthesis, reactivity and catalysis, micro and nano-particle formation, molecular recognition, as well as enhanced extraction processes with increased selectivity. © 2016 WILEY-VCH Verlag GmbH & Co.

    A versatile gold nanoparticle-based multifunctional nanocomposite AuNP@CD-AD-DOX/RGD was constructed flexibly via host-guest interaction for targeted cancer chemotherapy. The pH-sensitive anticancer prodrug AD-Hyd-DOX and the cancer-targeted peptide AD-PEG8-GRGDS were modified on the surface of AuNP@CD simultaneously, which endowed the resultant nanocomposite with the capability to selectively eliminate cancer cells. In vitro studies indicated that the AuNP@CD-AD-DOX/RGD nanocomposite was preferentially uptaken by cancer cells via receptor-mediated endocytosis. Subsequently, anticancer drug DOX was released rapidly upon the intracellular trigger of the acid microenvirenment of endo/lysosomes, inducing apoptosis in cancer cells. As the ideal drug nanocarrier, the multifunctional gold nanoparticles with the active targeting and controllable intracellular release ability hold the great potential in cancer therapy.

    There are several compounds for which there exists a disconnect between porosity as predicted by crystallography and porosity measured by gas sorption analysis. In this paper, the Zn-based analogue of Cu(3)(btc)(2) (HKUST-1), Zn(3)(btc)(2) (Zn-HKUST-1; btc = 1,3,5-benzenetricarboxylate) is investigated. Conventional analysis of Zn-HKUST-1 by powder X-ray diffraction and gas sorption indicates retention of crystalline structure but negligible nitrogen uptake at 77 K. By using positron annihilation lifetime spectroscopy, a densified surface layer preventing the entry of even small molecular species into the crystal framework is revealed. The material is shown to have inherent surface instability after solvent removal, rendering it impermeable to molecular guests irrespective of handling and processing methods. This previously unobserved surface instability may provide insight into the failure of other microporous coordination polymers to exhibit significant porosity despite crystal structures indicative of regular, interconnected, microporous networks.

  15. [Kidney transplantation epidemiology in France].

    Hiesse, Christian

    2013-11-01

    Kidney transplantation activity in France is among the most important worldwide: in 2011, 2976 transplants have been performed (47.5 per million population), and the number of patients living with a functional graft is estimated around 30,000, representing 44.7% of all patients (n = 67,270) treated for end-stage renal failure. However, the rate of preemptive kidney transplants remains very low, only 3.3% of incident patients starting renal replacement therapy. The analysis of demand showed a progressive increase in recent years, as demonstrated by the registration rate on the kidney transplantation waiting list, increasing by 5% yearly between 2006 and 2010, but with huge differences according to age categories and regional registration areas, reflecting discrepant appreciations in indications for kidney transplantation. The median waiting time between registration and transplantation increased progressively in recent years, reaching 22.3 months with considerable variations according to regional areas and transplantation teams. Kidney transplantation activity, while increasing continuously, is far to cover the rising demand, and inexorably patients accumulate on the waiting list (around 9000 patients were registered by January 2012). This situation is the consequence of insufficient organ procurement activity. The deceased organ procurement rate remained high: 1572 harvested donors in 2011 (24.1 per million population), but the proportion of older donors rose in recent years, to reach the rate of 26% of donors older than 65 years in 2011. The procurement activity of donors after cardiac arrest was reintroduced in 2006, but increased slowly: 65 transplants were performed in 2011 using kidney procured in non heart-beating donors. The living donor kidney transplantation activity has markedly increased recently: 302 living donor transplantations were performed in 2011, representing 10.1% of the kidney transplantations. Facing the predictable increase in the number of

    Clathrate hydrates are known to form a thin film along a guest/host boundary. We present here the first report of tetrahydrofuran (THF) clathrate hydrate formation in a THF/water concentration boundary layer. We found that the THF-water system also forms a hydrate film separating the guest/host phases. The lateral growth rate of the film increases as supercooling increases. The thickness of the film at the growth tip decreases as supercooling and the lateral growth rate increase. These tendencies are consistent with reports of experiments for other hydrates and predictions of heat-transfer models. After film formation and slight melting, two types of growth modes are observed, depending on temperature T. At T = 3.0 degrees C, the film slowly thickens. The thickening rate is much lower than the lateral growth rate, as reported for other hydrates. At T agglomerate of small polycrystalline hydrates forms in each phase. Grain boundaries in the film and pore spaces in the agglomerate act as paths for permeation of each liquid. Timing when continuous nucleation starts is dominantly controlled by the time of initiation of liquid permeation through the film. Digital particle image velocimetry analysis of the agglomerate shows that it expands not by growth at the advancing front but rather by continuous nucleation in the interior. Expansion rates of the agglomerate tend to be higher for the cases of multipermeation paths in the film and the thinner film. We suppose that the growth mode transition to continuous nucleation is caused by the memory effect due to slight melting of the hydrate film.

  17. Computational Calorimetry: High-Precision Calculation of Host–Guest Binding Thermodynamics

    Science.gov (United States)

    2015-01-01

    We present a strategy for carrying out high-precision calculations of binding free energy and binding enthalpy values from molecular dynamics simulations with explicit solvent. The approach is used to calculate the thermodynamic profiles for binding of nine small molecule guests to either the cucurbit[7]uril (CB7) or β-cyclodextrin (βCD) host. For these systems, calculations using commodity hardware can yield binding free energy and binding enthalpy values with a precision of ∼0.5 kcal/mol (95% CI) in a matter of days. Crucially, the self-consistency of the approach is established by calculating the binding enthalpy directly, via end point potential energy calculations, and indirectly, via the temperature dependence of the binding free energy, i.e., by the van’t Hoff equation. Excellent agreement between the direct and van’t Hoff methods is demonstrated for both host–guest systems and an ion-pair model system for which particularly well-converged results are attainable. Additionally, we find that hydrogen mass repartitioning allows marked acceleration of the calculations with no discernible cost in precision or accuracy. Finally, we provide guidance for accurately assessing numerical uncertainty of the results in settings where complex correlations in the time series can pose challenges to statistical analysis. The routine nature and high precision of these binding calculations opens the possibility of including measured binding thermodynamics as target data in force field optimization so that simulations may be used to reliably interpret experimental data and guide molecular design.

    Full Text Available In this paper I will analyze Serbian documentary films about guest workers dating from the last decade of the 20th and the first decade of the 21st century, using the perspective of visual anthropology. I question the popular cultural notions about guest workers in films Весеље у Ждрелу (A Celebration in Zdrelo by author Kamenko Katic, Звона позне јесени (The Bells of Late Autumn by author Zoran Milenovic, Кад је Милорад удавао ћерку (When Milorad Gave His Daughter in Marriage by author Vladimir Milisavljevic, Странац тамо, странац овде (A Foreigner There, a Foreigner Here by author Sandra Mandic and 242 метра живота (242 Meters of Life by author Novica Savic. The films deal with a number of issues: the economic aspects of guest workers’ lives, their liminal character, the issues of the second and third generations of guest workers, going away "temporarily" to work, and religious rituals. Even though the films were made recently, they all follow the lives of Vlach and Serbian, or rather Yugoslav guest workers who left to find temporary work abroad in Western Europe in the 1960’s and 1970’s. This serves the purpose of avoiding to deal with contemporary reasons for emigrating from Serbia and thus the possible critiques of current regimes or policies in power at the time the films were made.

    We explored, for the first time, young adult roll-your-own smokers' response to using plain packaging in real-world settings. Naturalistic research was employed, where 133 French young adult smokers (18-25 years of age) used plain roll-your-own packs for 10 days; the plain packs they were provided with contained their usual brand of rolling tobacco and displayed the name of their usual brand. Participants were recruited in five cities in France (Paris, Marseille, Metz, Nantes, Toulouse) and completed two questionnaires to measure their response to their own branded packs and the plain packs. Both questionnaires assessed pack perceptions, brand attachment, product perceptions (eg, taste, quality, natural), feelings about smoking (satisfying, pleasurable), feelings when using the pack in front of others (embarrassment, image), warning response (credibility, awareness of risks) and smoking-related behaviour (eg, consumption, quitting). Compared to their own fully branded packs, plain packs were associated with less positive pack and product perceptions, lower brand attachment and less positive feelings about smoking and feelings when using the pack in front of others. Participants were also more likely to report feeling like reducing consumption and quitting when using the plain packs, and more likely to feel like missing out on rolling a cigarette. No significant differences between the two pack types (plain and branded) were found in terms of credibility of warnings and perceptions of level of tar. The study suggests that the impacts of plain packaging for roll-your-own cigarette smokers are the same as for smokers of factory-made cigarettes. Published by the BMJ Publishing Group Limited.

    The author presents, comments and discusses various data related to photovoltaic energy production in France: evolution of installed power until 2013, installed power, production, hours per year and load factor for different countries (France, Spain, Germany and Italy) and for the different French regions. He highlights and comments the intermittency of photovoltaic production in France. This intermittency is related to the difference between day and night, to the difference between seasons, and to weather conditions. He discusses the possible solutions to this intermittency. In this respect, he outlines that the expansion of the photovoltaic production and the use of interconnection do not solve the problem, and discusses the possibility of massive storage and the possible interest of local consumption

    1983-01-01

    Energy planning in France must compensate for a lack of natural resources and a 77% dependence on imports with conservation, an increased use of domestic sources, and diversified supplies. One problem is a high per-capita energy consumption that, although only half that of the US, has been a financial drain in recent years. Current plans to reduce oil consumption 25% by 1990 and energy dependence to less than 50% include conservation goals set for each sector. Nuclear energy is a cost-effective energy source that is compatible with France's energy goals and is the focus of much energy research. The emphasis on realistic goals and continuity are basic to France's continued success in energy planning. 4 figures, 10 tables

  9. Nuclear energy education and training in France

    International Nuclear Information System (INIS)

    2010-01-01

    In its continuing use of nuclear power, France faces numerous challenges, including the operation and maintenance of its existing array of reactors, waste management, the decommissioning of obsolete reactors, and research and development for future nuclear systems. All of these efforts must recognize and conform to international requirements. These activities mean that all participants in the French nuclear industry must continually update their approaches and skills, with respect to both domestic and worldwide nuclear power development. This requirement calls for the hiring and training of thousands of scientists and engineers each year in France and its partner or customer countries. Over the next ten years, domestic and international nuclear power activities in France will call for the recruitment of about 13,000 engineers with Master of Science or Ph.D. degrees, and 10,000 science technicians and operators with Bachelor of Science degrees. The chief employers will be EDF, AREVA, GDF-Suez, national agencies such as the Agence nationale pour la gestion des dechets radioactifs (ANDRA), sub-contractors, and R and D agencies such as the Commissariat a l'Energie Atomique et aux Energies Alternatives (CEA), and the technical safety organization, Institut de Radioprotection et de Surete Nucleaire (IRSN). France has made a commitment to support countries that are ready to create the human, institutional, and technical conditions required to establish a civilian nuclear energy programme that meets all the requirements of safety, security, non-proliferation and environmental protection for present and future generations. These efforts are conducted through the France International Nuclear Agency (AFNI). In response to the need for competence-building in nuclear energy production, France now offers training opportunities in both French and English education programmes. Partnerships created by French nuclear energy participants and by AFNI can provide dedicated programmes

    We present 16 objects from the larger GTO + DAO T Tauri star samples described by Ardila et al. (2013ApJS..207....1A; focusing on the hot gas emission lines) and France et al. (2012, J/ApJ/756/171; focusing on the molecular circumstellar environment). Eleven of the 16 sources were observed as part of the DAO of Tau guest observing program (PID 11616; PI: G. Herczeg), four were part of the COS Guaranteed Time Observing program on protoplanetary disks (PIDs 11533 and 12036; PI: J. Green), and we have included archival STIS observations of the well-studied CTTS TW Hya (Herczeg et al. 2002ApJ...572..310H, 2004ApJ...607..369H), obtained through StarCAT (Ayres 2010, J/ApJS/187/149). The targets were selected by the availability of reconstructed Lyα spectra, as this emission line is a critical component to the intrinsic CTTS UV radiation field (Schindhelm et al. 2012ApJ...756L..23S) and has not been uniformly included in recent studies of the CTTS radiation field (e.g., Ingleby et al. 2011AJ....141..127I; Yang et al. 2012, J/ApJ/744/121). Most of the targets were observed with the medium-resolution FUV modes of COS (G130M and G160M; Green et al. 2012ApJ...744...60G). (2 data files).

    Infant food diversification has undergone a rapid succession of good practice recommendations in France, but there has been no assessment of pediatrician practices on food diversification. To assess the practices of pediatricians in relation to current recommendations of the French Society of Pediatrics on infant food diversification. This was an observational study conducted from 1 November 2014 to 31 March 2015. The study population consisted of 97 pediatricians in the Var department and 84 pediatric residents assigned to the University of Aix-Marseille in France. A questionnaire was sent by email or post to determine physician characteristics, food diversification methods in healthy children and those at atopic risk, and how the pediatric consultation was conducted. The expected answers were based on the most recent recommendations of the French Society of Pediatrics published in 2008, updated from 2003. In summary, breastfeeding is recommended up to 6 months. Food diversification can be started between 4 and 6 months in children with no allergy risk. Gluten, honey, legumes and cow's milk are introduced between 4 and 7 months, after 12 months and after 36 months, respectively. In atopic children, food diversification is delayed until after 6 months and the most allergenic foods (nuts, exotic fruits, peanuts, and shellfish) are introduced after the age of 12 months. Eighty-four responses were obtained (51%): 50 pediatricians and 34 pediatric residents. Sixteen items were classified depending on whether or not an update after 2003 existed. Over 80% of the physicians responded as recommended for the recently updated items for the age of introduction of "solid food in healthy children", "gluten", "cow's milk protein hydrolysates", and "the time until introduction of cow's milk in the atopic child". At best, 65% of physicians responded in accordance with recommendations for items without a recent update, age of introduction of "cow's milk", "milk desserts

  16. The Future of the CEMAC CFA Franc

    Directory of Open Access Journals (Sweden)

    Julius Agbor Agbor

    2013-08-01

    Full Text Available A total of 80 currency boards have come into existence at some point since the mid-19th century, but to date only about 15 of them still exist, among which is the CFA franc monetary zone. The future sustainability of the CFA franc zone, to which the CEMAC CFA franc belongs, is increasingly questioned in the light of increasing asymmetries in exposure to external shocks, differential speeds of adjustment of the real exchange rate following shocks, differential impacts in economic fundamentals, and low levels of intra-regional trade and financial flows between CEMAC and WAEMU. For the CEMAC bloc of countries in particular, the future sustainability of the fixed exchange regime depends crucially on continued oil exports, which currently represent about 90percent of export revenues and 40 percent of GDP. Should oil reserves deplete in the near future or oil prices decline significantly, a substantial source of foreign reserves would be lost, thereby exposing the regime to collapse. Even without resource depletion, continued volatility in global financial markets is increasing the risks of collapse of the fixed exchange regime as oil and commodity price swings ignite currency speculation as well as render reserves much more volatile. Against this backdrop, the present study examines the stakes facing the CEMAC CFA franc, discusses the exit options from the currency board and makes recommendations towards a sustainable monetary policy framework for CEMAC countries going forward. The analysis points to the imperative of pursuing a full monetary union with a single CEMAC franc pegged to the U.S. dollar and further suggest that, like the experience of the eurozone, the CEMAC monetary arrangement can be best implemented only by complying with the principle of political union.

    2013-01-01

    Important efforts have been made in recent years to develop climate services in France. Many initiatives have emerged to build an adapted System of information. This development is consistent with legislative and regulatory obligations, with a concern for economic advance, or a citizen questioning related to global change. The web portal 'DRIAS, les futurs du climat' provides an easy access to climate scenarios for France, opened to everyone concerned by impact and adaptation to climate change. This achievement results of a close co-operation between the major French climate modelling groups and the operational services of Meteo-France. It has been benefiting from the support of the Ministry in charge of Sustainable Development namely through its GICC program. The next steps with DRIAS will be defined both by a strong consistency with the scientific community work and by the requirements and expectations of users. In this, it is a real service. Following a different approach more focused on the specific and advanced needs of particular users, the French projects INVULNERABLe and SECIF sought to create a relevant and tailored to the industrial sector. This kind of products requires a support to educate operational users to climate change issue, and then to enhance the interface between climatologists and skilled users within the concerned companies. Both approaches are representative of current efforts of the French national scientific community to provide a useful part of the knowledge developed by the Academia and Meteo-France. The various initiatives are carried out with the wish to share and be consistent with research community work. They are mutually enriching, and with all stakeholders involved, they gradually build a real climate service in France. (authors)

    Thermal effects of inclusion processes of {alpha}-, {beta}-, {gamma}- and M{beta}-cyclodextrin with resveratrol (RES) in aqueous solutions were determined by isothermal titration calorimetry (ITC) with nanowatt sensitivity at the temperature of 298.15 K. Standard enthalpy changes, stoichiometry and equilibrium constants of the inclusion complexes were derived from the direct calorimetric data utilizing nonlinear simulation. The thermodynamic parameters were discussed in the light of weak interactions between the host and the guest molecules combining with UV spectral message. The results indicate that all of the complexes formed in the aqueous solutions are in 1:1 stoichiometry. The binding processes of {alpha}-, {beta}- and M{beta}-cyclodextrin with the guest are mainly driven by enthalpy, while that of {gamma}-cyclodextrin with the drug is driven by both enthalpy and entropy.

    An amide-functionalized metal organic framework (MOF) material, MFM-136, shows a high CO 2 uptake of 12.6 mmol g -1 at 20 bar and 298 K. MFM-136 is the first example of an acylamide pyrimidyl isophthalate MOF without open metal sites and, thus, provides a unique platform to study guest binding, particularly the role of free amides. Neutron diffraction reveals that, surprisingly, there is no direct binding between the adsorbed CO 2 /CH 4 molecules and the pendant amide group in the pore. This observation has been confirmed unambiguously by inelastic neutron spectroscopy. This suggests that introduction of functional groups solely may not necessarily induce specific guest-host binding in porous materials, but it is a combination of pore size, geometry, and functional group that leads to enhanced gas adsorption properties.

    Full Text Available The Particle Swarm Optimization (PSO and Support Vector Machines (SVMs approaches are used for predicting the thermodynamic parameters for the 1:1 inclusion complexation of chiral guests with β-cyclodextrin. A PSO is adopted for descriptor selection in the quantitative structure-property relationships (QSPR of a dataset of 74 chiral guests due to its simplicity, speed, and consistency. The modified PSO is then combined with SVMs for its good approximating properties, to generate a QSPR model with the selected features. Linear, polynomial, and Gaussian radial basis functions are used as kernels in SVMs. All models have demonstrated an impressive performance with R2 higher than 0.8.

    Hybrid white organic light emitting diodes (HWOLEDs) with fluorescence and phosphorescence hybrid structures are studied in this work. HWOLEDs were fabricated with blue/red emitting layers: fluorescent host material doped with sky blue material, and bipolar phosphorescent host emitting material doped with red dopant material. An electron blocking layer is applied that provides hole red guest emitter hole trapping effects, increases the charge carrier injection quantity into the emitting layers and controls the recombination zone (RZ) that helps balance the device color. Spacer layers were also inserted to expand the RZ, increase efficiency and reduce energy quenching along with roll-off effects.

    Complexation between a triptycene-derived macrotricyclic polyether containing two dibenzo-[30]-crown-10 cavities and different functionalized paraquat derivatives, diquat, and a 2,7-diazapyrenium salt in both solution and solid state was investigated in detail. It was found that depending on the guests with different terminal functional groups and structures, the macrotricyclic polyether could form 1:1 or 1:2 complexes with the guests in different complexation modes in solution and also in the solid state. Especially, the conformation of the macrotricyclic polyether was efficiently adjusted by the encapsulated guests, which was to some extent similar to substrate-induced fit of enzymes. Moreover, the binding and releasing of the guests in the complexes could be controlled by potassium ions.

    New topochemistry in simple molecular systems can be explored at high pressure. Here we examine the binary nitrogen/hydrogen system using Raman spectroscopy, synchrotron X-ray diffraction, synchrotron infrared microspectroscopy and visual observation. We find a eutectic-type binary phase diagram with two stable high-pressure van der Waals compounds, which we identify as (N2)6(H2)7 and N2(H2)2. The former represents a new type of van der Waals host-guest compound in which hydrogen molecules are contained within channels in a nitrogen lattice. This compound shows evidence for a gradual, pressure-induced change in bonding from van der Waals to ionic interactions near 50 GPa, forming an amorphous dinitrogen network containing ionized ammonia in a room-temperature analogue of the Haber-Bosch process. Hydrazine is recovered on decompression. The nitrogen-hydrogen system demonstrates the potential for new pressure-driven chemistry in high-pressure structures and the promise of tailoring molecular interactions for materials synthesis.

    The kaolinite-glycine intercalation compound was successfully formed by displacing intercalated guest water molecules in kaolinite hydrate as a precursor. The microstructure of the compound was characterized by X-ray diffraction, Fourier Transform Infrared Spectroscopy and Scanning Electron Microscope. Results show that glycine can only be intercalated into hydrated kaolinite to form glycine-kaolinite by utilizing water molecules as a transition phase. The intercalated glycine molecules were squeezed partially into the ditrigonal holes in the silicate layer, resulting in the interlayer distance of kaolinite reaching 1.03nm. The proper intercalation temperature range was between 20°C and 80°C. An intercalation time of 24h or above was necessary to ensure the complete formation of kaolinite-glycine. The highest intercalation degree of about 84% appeared when the system was reacted at the temperature of 80°C for 48h. There were two activation energies for the intercalation of glycine into kaolinite, one being 21kJ/mol within the temperature range of 20-65°C and the other 5.8kJ/mol between 65°C and 80°C. The intercalation degree (N) and intercalation velocity (v) of as a function of intercalation time (t) can be empirically expressed as N=-79.35e(-)(t)(/14.8)+80.1 and v=5.37e(-)(t)(/14.8), respectively.

    In this study, we design and fabricate phosphor-doped host-guest structure organic light-emitting diodes (OLEDs), where the blue-ray iridium complex electrophosphorescent material FIrpic acts as object material. Properties of the device can be accommodated by changing the host materials, dopant concentration and thickness of the light-emitting layer. The study shows that the host material N,N'-dicarbazolyl-3,5-benzene (mCP) has a higher triplet excited state energy level, which can effectively prevent FIrpic triplet excited state energy backtracking to host material, thus the luminous efficiency is improved. When mCP is selected as the host material, the thickness of the light-emitting layer is 30 nm and the dopant concentration is 8 wt%, the excitons can be effectively confined in the light-emitting region. As a result, the maximum current efficiency and the maximum brightness of the blue device can reach 15.5 cd/A and 7 196.3 cd/m2, respectively.

    Decades after the birth of supramolecular chemistry, there are many techniques to measure noncovalent interactions, such as hydrogen bonding, under equilibrium conditions. As ensembles of molecules rapidly lose coherence, we cannot extrapolate bulk data to single-molecule events under non-equilibrium conditions, more relevant to the dynamics of biological systems. We present a new method that exploits the high force resolution of optical tweezers to measure at the single molecule level the mechanical strength of a hydrogen bonded host-guest pair out of equilibrium and under near-physiological conditions. We utilize a DNA reporter to unambiguously isolate single binding events. The Hamilton receptor-cyanuric acid host-guest system is used as a test bed. The force required to dissociate the host-guest system is ∼17 pN and increases with the pulling rate as expected for a system under non-equilibrium conditions. Blocking one of the hydrogen bonding sites results in a significant decrease of the force-to-break by 1-2 pN, pointing out the ability of the method to resolve subtle changes in the mechanical strength of the binding due to the individual H-bonding components. We believe the method will prove to be a versatile tool to address important questions in supramolecular chemistry.

  13. Smart protein biogate as a mediator to regulate competitive host-guest interaction for sensitive ratiometric electrochemical assay of prion

    2015-11-01

    A novel competitive host-guest strategy regulated by protein biogate was developed for sensitive and selective analysis of prion protein. The methylene blue (MB)-tagged prion aptamer (MB-Apt) was introduced to the multiwalled carbon nanotubes-β-cyclodextrins (MWCNTs-β-CD) composites-modified glassy carbon (GC) electrode through the host-guest interaction between β-CD and MB. In the absence of prion, MB-Apt could be displaced by ferrocenecarboxylic acid (FCA) due to its stronger binding affinity to β-CD, resulting in a large oxidation peak of FCA. However, in the presence of prion, the specific prion-aptamer interaction drove the formation of protein biogate to seal the cavity of β-CD, which hindered the guest displacement of MB by FCA and resulted in the oxidation peak current of MB (IMB) increased and that of FCA (IFCA) decreased. The developed aptasensor showed good response towards the target (prion protein) with a low detection limit of 160 fM. By changing the specific aptamers, this strategy could be easily extended to detect other proteins, showing promising potential for extensive applications in bioanalysis.

    The clinical application of nanoparticular Gd(III) based contrast agents for tumor molecular MRI has been hindered by safety concerns associated with prolonged tissue retention, although they can produce strong tumor enhancement. In this study, a targeted well-defined cyclodextrin-based nanoglobular contrast agent was developed through self-assembly driven by host-guest interactions for safe and effective cancer molecular MRI. Multiple β-cyclodextrins attached POSS (polyhedral oligomeric silsesquioxane) nanoglobule was used as host molecule. Adamantane-modified macrocyclic Gd(III) contrast agent, cRGD (cyclic RGDfK peptide) targeting ligand and fluorescent probe was used as guest molecules. The targeted host-guest nanoglobular contrast agent cRGD-POSS-βCD-(DOTA-Gd) specifically bond to αvβ3 integrin in malignant 4T1 breast tumor and provided greater contrast enhancement than the corresponding non-targeted agent. The agent also provided significant fluorescence signal in tumor tissue. The histological analysis of the tumor tissue confirmed its specific and effective targeting to αvβ3 integrin. The targeted imaging agent has a potential for specific cancer molecular MR and fluorescent imaging. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Several Cord Blood (CB) Bank studies suggested that ethnicity impaired CB unit (CBU) qualification. The Bone Marrow Donors Worldwide registries present an over-representation of unrelated donors (UD) from Northwestern European descent. This raises the question of equality of access to hematopoietic stem cells transplant, especially in the Mediterranean zone, which has taken in many waves of immigration. The aim of our study is to address whether, in the Marseille CB Bank, CBU qualification rate is impaired by geographic origin. The study compared biological characteristics of 106 CBU disqualified for total nucleated cell (TNC) count (dCBU) and 136 qualified CBU in relation to registry enrichment and haplotype origin. A high proportion (>80%) of both dCBU and CBU had at least one non-European haplotype and enrich CB and UD registries to a higher extent than those with two European haplotypes (Pdiverse Mediterranean origins do not have an impact on the CBU qualification rate. Partnership with Mediterranean birth clinics with highly trained staff is a reasonable option to increase the HLA diversity of CB Bank inventories and to improve the representation of minorities.

    2005-09-01

    During the G8 summit at Kananaskis (Canada) in June 2002, G8 Leaders decided to launch the Global Partnership against the Spread of Weapons and Materials of Mass Destruction. Under this initiative, partners support specific cooperation projects to address non-proliferation, disarmament, counter-terrorism and nuclear safety issues. Since then, thirteen other donor countries have joined the initiative from which the Ukraine may also now benefit. France intends to make an effective contribution, up to 750 million euros, to the implementation of this initiative, giving priority to a genuine partnership between France and Russia covering projects in the nuclear, chemical and biological fields. France intends to be involved in the various fields identified at Kananaskis: in the nuclear field, it is participating in nuclear submarine dismantling actions and contributes to the improvement of nuclear safety and security. It also supports the program for the disposition of Russian weapons-grade plutonium designated as no longer required for defence purposes. France is also involved in the destruction of chemical weapons and intends to develop responses to bio-terrorist threats, while promoting reemployment of scientists. To optimise its action, France has committed itself to both multilateral and bilateral programs. In the multilateral framework, France contributes to: - the NDEP fund (Northern Dimension Environment Partnership) which will finance projects related to the dismantling of nuclear submarines and remediation of the sites concerned; - the MPDG (Multilateral Plutonium Disposition Group), whose objective is to enable the disposition of Russian weapons-grade plutonium designated as no longer required for defence purposes; - the construction of the new Chernobyl shelter in the Ukraine. France is also developing bilateral cooperation, primarily with Russia: - in the nuclear field, the implementing agreement negotiated in the framework of the Multilateral Environmental

    Full Text Available The sustainable development of the festival depends on the support and participation of residents and tourists. There are a number of practical and theoretical gaps regarding the hosts and guests in festival literature. This study attempts to fill the host–guest gap based on the theory of reasoned action to construct and exam a relationship model. Taking the 2016 Summer Festival during busy season as an example in Hualien, 1165 questionnaires were valid, and data were analyzed by SEM (structural equation modeling. Results showed that the hosts had higher perception than the guests in terms of the festival benefits, identity, and support. This study has two concept models: the guest model and the host model. In the host model, the local-development benefits have more positive relationships to affect the festival support and festival identity than the recreation-experience benefits. On the other hand, the recreation-experience benefits could affect the festival support, but the festival identity could not in the guest model. The results of this study indicate that the festival organizers or the public sectors must be pay attention to the viewpoints of the guests and hosts in order to achieve the sustainable development objectives.

    Full Text Available We compare second birth risks in France and western Germany using data from the Family and Fertility Survey. Second birth risks are higher for highly educated women than for women with lower education in both countries. In western Germany, the positive effect weakens after controlling for the education level of the partner. The positive effect of French women's education remains unchanged, even after controlling for the partners' characteristics. We interpret this finding in the sense that work and family life are more compatible in France, where highly educated women can turn their education more often into work opportunities and income. West German women often have to make a decision between an employment career and motherhood as two exclusive life options. In such a situation, it is primarily the partners' earning potential that influences fertility.

    Full Text Available Phlebotomus perniciosus was identified morphologically in samples from France and northeast Spain, and individuals were then characterized at three polymorphic isoenzyme loci (by isoelectrofocusing and at the mitochondrial DNA locus (by comparative DNA sequence analysis of a fragment of the Cytochrome b gene. The four polymorphic loci gave conflicting patterns of population relationships, which can be explained by hypothesizing different amounts of gene introgression at each locus when two distinctive lineages met in southern France or northeast Spain after isolation in southern Italy and Spain during the Pleistocene Ice Ages. P. perniciosus is an important vector of Leishmania infantum and so these population differentiation studies are relevant for predicting the emergence and spread of leishmaniasis in relation to environmental changes, including climate.

    1978-01-01

    With the increasing energy needs of mankind and the earth's necessarily limited resources of fuel, the time will come when the demand for hydrocarbons will exceed the world production capacity. This situation will subsequently get even worse because of the depletion of recoverable reserves. Massive recourse to nuclear and solar energy thus appears indispensable, and the use of hydrogen as a vector for such energies has been under consideration for several years, especially in France where petroleum resources are very limited. Gaz de France has been doing research on the mass production of hydrogen by the decomposition of water and has just come to rather pessimistic conclusions as to the competitiveness of thermochemical processes in comparison with electrolytic methods. However, the electrolysis of water offers interesting prospects providing its efficiency and economics can be improved. Furthermore research on the storage and transportation of hydrogen has already enabled some conclusions to be drawn in these fields where gaseous vectors have very encouraging possibilities [fr

  7. Guide about petroleum strategic stockpiles in France

    International Nuclear Information System (INIS)

    2004-03-01

    The strategic character of petroleum products has been perceived since the first world war. It has led France to impose the petroleum operators to make stockpiles to provide against the consequences of a serious disruption of supplies. As a difference with some other industrialized countries like the USA or Japan, French stockpiles are made of finite products. A balanced geographical distribution of these stocks over the whole national territory increases their efficiency. Stockpiles of IEA member states must represent 90 days of net imports while those of European Union member states must represent 90 days of average domestic consumption. In France, each chartered operator contributes to the strategic storage and the stored volumes are defined by the law no 92-1443 from December 31, 1992. These stocks are permanently controlled and financial sanctions are applied in case of infraction. Particular dispositions are applied in overseas departments which are summarized in this paper.

    The enterovirus (EV) types echovirus (E-) 5, E-9, and E-18, and coxsackievirus (CV-) A9 are infrequently reported in human diseases and their epidemiologic features are poorly defined. Virus transmission patterns between countries have been estimated with phylogenetic data derived from the 1D/VP1 and 3CD gene sequences of a sample of 74 strains obtained in France (2000-2012) and Tunisia (2011-2013) and from the publicly available sequences. The EV types (E-5, E-9, and E-18) exhibited a lower worldwide genetic diversity (respective number of genogroups: 4, 5, and 3) in comparison to CV-A9 (n = 10). The phylogenetic trees estimated with both 1D/VP1 and 3CD sequence data showed variations in the number of co-circulating lineages over the last 20 years among the four EV types. Despite the low number of genogroups in E-18, the virus exhibited the highest number of recombinant 3CD lineages (n = 10) versus 4 (E-5) to 8 (E-9). The phylogenies provided evidence of multiple transportation events between France and Tunisia involving E-5, E-9, E-18, and CV-A9 strains. Virus spread events between France and 17 other countries in five continents had high probabilities of occurrence as those between Tunisia and two European countries other than France. All transportation events were supported by BF values > 10. Inferring the source of virus transmission from phylogenetic data may provide insights into the patterns of sporadic and epidemic diseases caused by EVs.

    Full Text Available Gongylonema spp. are cosmopolitan spirurid nematodes that are common parasites of wild and domesticated mammals and birds. Gongylonema pulchrum Molin, 1857 is most common in ruminants, where it invades mucosa and submucosa of the mouth, tongue, oesophagus and forestomachs. It extremely rarely occurs in man, and fewer than 60 cases have been reported worldwide. We report a case from the Alsace region, which appears to be the first case of human gongylonemosis described in France.

    One of the goals set by the Grenelle agreement was to reach a ratio of 23% for the part of renewable energies in the final energies consumed in France by 2020. In 2005 this ratio was 10 per cent. In this article the situation in 2010 for wind energy, solar energy, biomass, wood heating and geothermal energy are reported. It appears that the results are promising but the reduction of fiscal incentives might jeopardize the objective for 2020. (A.C.)

    During the last decade conflicts about expression on religion have increased globally. Generally, these conflicts are regarded as a conflict between freedom of speech and freedom of thought, conscience and religion. In France there are many active religious interest groups that aim to protect a certain religion in society. They often initiate judicial proceedings seeking to prohibit certain kinds of speech on their religion. This practice has resulted in a rich case law on the limits of expre...

  20. Insurance of the Nuclear Risk in France

    Brassard, Guy

    2012-01-01

    This March, Japan commemorated the first anniversary of the Fukushima tragedy, when an unhappy combination of natural disasters led to a nuclear accident. The material and human damage was enormous and it will be decades before memories fade and the Japanese can try to forget this tragedy, which attests to the great vulnerability of - even the most advanced - economies to natural and technological risks. In the wake of the accident, there has been much debate on the pertinence of the use of nuclear fission in energy production, particularly in France. Without going over these debates once again, it is nonetheless legitimate to ask not just how well equipped we are to prevent nuclear risks, but also how the consequences of a potential nuclear disaster would be dealt with in this country. It is this question that Guy Brassard latches on to. After reminding us of the limits of the responsibility of EDF (Electricite de France) and the state in France regarding the indemnification of the damage that would ensue from such a disaster, Brassard stresses the inadequacy of the guarantees in force and calls for the creation of a reserve fund for exceptional events. He stresses the need to mitigate the nuclear risk through a clear assessment of power stations on the basis of uniform security parameters, a publicly avail able economic analysis of the electricity mix, and the establishment of measures of efficiency and prudence in the use of France's nuclear resources. He ends by proposing a model, based on a large number of international studies, for calculating the costs of a scheme for insuring against exceptional risks. From these it emerges that a very moderate increase in the price of electricity would make it possible to set aside 100 billion euros over 18 years to meet a risk that would arise only once every century. A relatively negligible investment for the future by comparison with the cost to the public finances of such a disaster occurring. (author)
