    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

    Botulinum neurotoxin type F (BoNT/F) may be produced by Clostridium botulinum alone or in combination with another toxin type such as BoNT/A or BoNT/B. Type F neurotoxin gene sequences have been further classified into seven toxin subtypes. Recently, the genome sequence of one strain of C. botulinum (Af84) was shown to contain three neurotoxin genes (bont/F4, bont/F5, and bont/A2). In this study, eight strains containing bont/F4 and seven strains containing bont/F5 were examined. Culture supernatants produced by these strains were incubated with BoNT/F-specific peptide substrates. Cleavage products of these peptides were subjected to mass spectral analysis, allowing detection of the BoNT/F subtypes present in the culture supernatants. PCR analysis demonstrated that a plasmid-specific marker (PL-6) was observed only among strains containing bont/F5. Among these strains, Southern hybridization revealed the presence of an approximately 242-kb plasmid harboring bont/F5. Genome sequencing of four of these strains revealed that the genomic backgrounds of strains harboring either bont/F4 or bont/F5 are diverse. None of the strains analyzed in this study were shown to produce BoNT/F4 and BoNT/F5 simultaneously, suggesting that strain Af84 is unusual. Finally, these data support a role for the mobility of a bont/F5-carrying plasmid among strains of diverse genomic backgrounds.

    Myofascial pain syndrome is defined as subacute or chronic pain with sensory, motor and autonomic symptoms referred from active trigger points with associated painful dysfunctions. Authors present the usefulness of botulinum toxin A or B (BoNT/A or BoNT/B) injected into target muscles since the toxin is capable of controlling not only the muscular spasm but mostly the pain by alternative mechanisms of action, which are discussed. Posology of BoNT, technical aspects and results are presented. BoNT represents an interesting and useful tool for an adequate management of patients with myofascial pain.

    The influence of the intracellular redox state on the hepatitis C virus (HCV) life cycle is poorly understood. This study demonstrated the anti-HCV activity of 2,3-dihydro-5-hydroxy-2,2-dipentyl-4,6-di-tert-butylbenzofuran (BO-653), a synthetic lipophilic antioxidant, and examined whether BO-653's antioxidant activity is integral to its anti-HCV activity. The anti-HCV activity of BO-653 was investigated in HuH-7 cells bearing an HCV subgenomic replicon (FLR3-1 cells) and in HuH-7 cells infected persistently with HCV (RMT-tri cells). BO-653 inhibition of HCV replication was also compared with that of several hydrophilic and lipophilic antioxidants. BO-653 suppressed HCV replication in FLR3-1 and RMT-tri cells in a concentration-dependent manner. The lipophilic antioxidants had stronger anti-HCV activities than the hydrophilic antioxidants, and BO-653 displayed the strongest anti-HCV activity of all the antioxidants examined. Therefore, the anti-HCV activity of BO-653 was examined in chimeric mice harboring human hepatocytes infected with HCV. The combination treatment of BO-653 and polyethylene glycol-conjugated interferon-α (PEG-IFN) decreased serum HCV RNA titer more than that seen with PEG-IFN alone. These findings suggest that both the lipophilic property and the antioxidant activity of BO-653 play an important role in the inhibition of HCV replication. Copyright © 2012 Wiley Periodicals, Inc.

    Full Text Available Transparency: Bacen versus BoE. The aim of this paper is to compare the degree of transparency of the Brazilian Central Bank (Bacen with the one verified in the Bank of England (BoE. In order to accomplish this objective, an indicator of transparency is built based on the information that each central bank provides to the public about its monetary policy, its expectation about the future of the economy, its intervention in the financial market, and if there are clear limits and restrictions to the release of information to the general public. The analysis suggests that the Bacen is less transparent and has a less individualistic Monetary Policy Committee in comparison with the BoE. Moreover, it indicates some procedures that could be adopted by the Bacen in order to make its monetary policy more transparent.

    Growth, single crystal X-ray diffraction, polarized Raman and infrared (IR) studies of BaHf(BO{sub 3}){sub 2} are presented. Raman and IR spectra of polycrystalline BaZr(BO{sub 3}){sub 2} are also reported to facilitate assignment of modes. BaHf(BO{sub 3}){sub 2} borate crystallizes in trigonal system, space group R3c, with lattice parameters: a=5.1540(4) Å, c=33.901(3) Å. It accommodates dolomite-like structure doubled in the c direction, which is built of alternating layers of HfO{sub 6} octahedra and BaO{sub 6} distorted trigonal prisms that are connected through borate groups. The obtained structural as well as spectroscopic data show that BaHf(BO{sub 3}){sub 2} is isostructural with BaZr(BO{sub 3}){sub 2} and the deviations from centrosymmetry is small. - Graphical abstract: Arrangement of BO{sub 3} groups in BaHf(BO{sub 3}){sub 2} along the c direction in one unit cell. Dark and light blue denote different borate groups. - Highlights: • BaHf(BO{sub 3}){sub 2} single crystals were grown. • X-ray diffraction showed that this borate crystallizes in the acentric R3c structure. • Raman and IR spectra were measured for BaHf(BO{sub 3}){sub 2} and BaZr(BO{sub 3}){sub 2}, respectively. • Assignment of modes is proposed.

    Bovine herpesvirus type 5 (BoHV-5) belongs to the family Herpesviridae, subfamily Alphaherpesvirinae, genus Varicellovirus. This virus is a major causative agent of non-suppurative meningoencephalitis in young cattle. It was first isolated in 1962 from a neurological disease outbreak in Australia. BoHV-5 is genetically and antigenically related to bovine herpesvirus type 1 (BoHV-1), a highly prevalent virus responsible for respiratory and genital disease in cattle. Initially, BoHV-5 was considered a subtype of BoHV-1 (BoHV-1.3). However, the exclusive presentation of outbreaks of neurological disease suggested that the virus was a new agent with characteristics of neuropathogenicity. Even though both are neurotropic viruses, only BoHV-5 is capable of replicating extensively in the central nervous system and inducing neurological disease. Occasionally, encephalitis caused by BoHV-1 has been reported. Like other alpha-herpesviruses, BoHV-5 can establish latency in nervous ganglia and, by stress factors or glucocorticoid treatment, latent virus can be reactivated. During episodes of reactivation, the virus is excreted in nasal, ocular and genital secretions and transmitted to other susceptible hosts. Recently, BoHV-5 has been associated with infection of the reproductive tract. The virus has been isolated and the presence of viral DNA has been demonstrated in semen samples from Brazil and Australia and natural transmission of the virus through contaminated semen has also been described. Embryos and oocytes are permissive for BoHV-5 infection and BoHV-5 DNA has been detected in the central nervous system of aborted fetuses. The objective of this review is to compile the limited information on the recent association between BoHV-5 and reproductive disorders in cattle. PMID:26623291

    Crystals of mixed alkali neodymium orthoborates, K_9Li_3Nd_3(BO_3)_7 and A_2LiNd(BO_3)_2 (A = Rb, Cs) were obtained by spontaneous crystallization. K_9Li_3Nd_3(BO_3)_7 crystallizes in space group P2/c with cell parameters of a = 11.4524(7) Aa, b = 10.1266(6) Aa, c = 12.3116 (10) Aa, β = 122.0090(10) . In the structure, NdO_8 polyhedra share corners and connect with planer BO_3 groups to form infinite [Nd_3B_3O_2_1]_n chains. These chains are linked by additional BO_3 groups to produce a double layer of [Nd_6B_6O_3_8]_n blocks in the ac plane with K and Li ions filled into the cavities. A_2LiNd(BO_3)_2 (A = Rb, Cs) crystallizes in space group Pbcm, with cell parameters of a = 7.113(2) Aa, b = 9.691(3) Aa and c = 10.135(3) Aa for Rb_2LiNd(BO_3)_2, and a = 7.2113(3) Aa, b = 9.9621(4) Aa, and c = 10.3347(4) Aa for Cs_2LiNd(BO_3)_2. In the structure, NdO_8 polyhedra are corner-sharing with each other and further interlinked by BO_3 groups to comprise the infinite [Nd_4B_4O_2_4] sheets in the bc plane, with Rb/Cs and Li ions occupying the interlayered space. The compounds show effective near-IR emission and their associated lifetimes are obtained by fluorescence spectra. (Copyright copyright 2016 WILEY-VCH Verlag GmbH and Co. KGaA, Weinheim)

    The comparison of Fe{sub 3}BO{sub 5} and Fe{sub 2}MnBO{sub 5} reveals that the 2Fe{sup 2+}: Fe{sup 3+} charge ordering of the former is suppressed in the latter. Spin dynamics probed by ac susceptibility are strongly affected by the substitution, inducing superparamagnetism at low temperature in Fe{sub 2}MnBO{sub 5}. Interestingly, for both oxyborates, glassiness is observed in the dielectric properties at low temperature, but only Fe{sub 3}BO{sub 5} shows a magnetodielectric effect close to its lower magnetic transition. A change in the electrical polarization, measured by pyroelectric current integration, is observed in Fe{sub 3}BO{sub 5} and is even more pronounced in Fe{sub 2}MnBO{sub 5}. Such results suggest that these oxyborates behave like antiferromagnetic relaxor ferroelectrics. These features are proposed to be related to the distribution of the species (Fe{sup 3+}, Fe{sup 2+} and Mn{sup 2+}) over the four transition metal sites forming the ludwigite structure. - Graphical abstract: 90 K [010] electron diffraction patterns of Fe{sub 3}BO{sub 5}. The yellow arrows in the pattern indicate the extra-spots corresponding to the superstructure induced by the charge ordering. - Highlights: • The TEM (ED) study of the Fe{sub 3}BO{sub 5} oxyborate at 90 K reveals a superstructure related to a Fe{sup 2+}/Fe{sup 3+} ordering. • The Fe{sub 2}MnBO{sub 5}, Mn-substituted counterpart, does not show such ordering. • Our magnetic and electric measurements demonstrate that these magnetic ferrites exhibit glassiness in their charges (relaxor-type) with additional superparamagnetism at low T for Fe{sub 2}MnBO{sub 5} and magnetodielectric coupling near T{sub N2}=72 K in Fe{sub 3}BO{sub 5}. • The pyroelectric measurements confirm the existence of a ferroelectric behavior in these antiferromagnets. Accordingly, our results open the route to the study of other large class of the M{sub 2}{sup 2+}M’{sup 3+}BO{sub 5} ludwigites and to their complex magnetism and its

    Nanocapsules consisting of B 2 O 3 /H 3 BO 3 encapsulating Fe-Gd cores have been synthesized by an arc-discharge process using metal-boron alloys as cathode. Most of the nanocapsules have a well-constructed shell/core structure with a uniform B 2 O 3 /H 3 BO 3 shell. Heat-treatment induces reactions between the shell and the core, resulting in the formation of a Fe 3 BO 5 +GdBO 3 matrix embedded with Fe nanoparticles, reduction of the metallic-core size and decrease of the blocking temperature T B . Above T B , the magnetization curves plotted vs. H/T overlap and show zero coercivity. Below T B , the coercivity shows a linear dependence when plotted vs. T 1/2 . However, the coercivity-T 1/2 curve below 60 K has a different slope from that above 60 K, indicating the existence of two different magnetic phases in the nanocapsules. Different from bulk Fe 3 BO 5 , nanoscale Fe 3 BO 5 particles have a lower transition temperature to the weak-ferromagnetic state, and magnetic hysteresis is absent due to size effects

According to their genotype, cows were classified in homozygous (R/R, N/N, or S/S and heterozygous (R/N, R/S, N/S. BLV molecular prevalence was 44%. The most frequent allele was BoLA-DRB3.2*22 (16.8%, alleles associated with resistance to BLV were BoLA-DRB3.2*8 (OR=1.489; P<0.10 and BoLA-DRB3.2*12 (OR=3.897; P<0.10 and allele BoLA-DRB3.2*16 (OR=0.710; P<0.10 was associated with susceptibility. Allele BoLA-DRB3.2*8 had the highest allelic frequency for negative cows (0.19. 63.7% of cows with genotype RN and 70% of cows with genotype RR were resistant to infection by BLV. Alleles R and S have a dominant effect on allele N (P<0.05. The use of reliable diagnostic techniques in conjunction with identification of resistant or susceptible animals can monitor the progress of the disease in dairy herds. Alleles BoLA-DRB3.2*8 and *12 were positively related to the disease and therefore cows have low risk of infection, unlike allele BoLA-DRB3.2*16 which was negatively related and animals have high risk for the disease.

With the emergence of DTT (Digital Terrestrial Television in Spain television networks, public and private, they have created new thematics channels focused on content for children. At the same time, with the rise of new electronic devices such as tablets and smartphones, they have moved such content to the network by creating of platforms whose programs are aimed childhood. The non-linearity and immediacy in consumption make the Internet becomes an active mean giving autonomy and freedom to access a multitude of content regardless of time and the device. In this situation the child consumers is the audience that worries both parents and educational institutions. Restless, therefore, that children do not find programs adjusted to their age. The quality concept harbors no concrete definition because of the multitude of factors and perspectives that influence it. This paper, and based on different measurement criteria set by countries like Argentina, Chile, Spain, France, Italy, Japan, Sweden, the University of Pennsylvania (USA or the ACTF (Australian Children´s Television Foundation poses as main objective to analyze the online platforms Clan RTVE, Neox Kidz and Boing of television TVE, Antena 3 and Telecinco, respectively, because they are considered spaces with audiovisual material created for children. With the intention of demonstrating that they are presented as quality environments for children who access them it will conduct a qualitative methodology. Using the content analysis technique to each of the animated titles we can say that the cartoons, as outlined above, are quality entertainment programs.

    Hyperhalogens were recently identified as a new class of highly electronagative species which are composed of metals and superhalogens. In this work, high-level theoretical calculations and photoelectron spectroscopy experiments are systematically conducted to investigate a series of coinage-metal-containing hyperhalogen anions, Cu(BO(2))(2)(-), Ag(BO(2))(2)(-), and Au(BO(2))(2)(-). The vertical electron detachment energy (VDE) of Ag(BO(2))(2)(-) is anomalously higher than those of Au(BO(2))(2)(-) and Cu(BO(2))(2)(-). In quantitative agreement with the experiment, high-level ab initio calculations reveal that spin-orbit coupling (SOC) lowers the VDE of Au(BO(2))(2)(-) significantly. The sizable magnitude of about 0.5 eV of SOC effect on the VDE of Au(BO(2))(2)(-) demonstrates that SOC plays an important role in the electronic structure of gold hyperhalogens. This study represents a new paradigm for relativistic electronic structure calculations for the one-electron-removal process of ionic Au(I)L(2) complexes, which is characterized by a substantial SOC effect.

    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)

    As of April 2010, all maternity care at government healthcare facilities in Sierra Leone is provided at no cost to patients. In late 2010, we conducted a community health census of 18 sections of the city of Bo (selected via randomized cluster sampling from 68 total sections). Among the 3421 women with a history of pregnancy who participated in the study, older women most often reported having a history of both home and hospital deliveries, while younger women showed a preference for hospital births. The proportion of lastborn children delivered at a healthcare facility increased from 71.8% of offspring 10-14 years old to 81.1% of those one to nine years old and 87.3% of infants born after April 2010. These findings suggest that the new maternal healthcare initiative has accelerated an existing trend toward a preference for healthcare facility births, at least in some urban parts of Sierra Leone. © 2012 The Authors Acta Obstetricia et Gynecologica Scandinavica© 2012 Nordic Federation of Societies of Obstetrics and Gynecology.

    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.

    2012-01-01

    The red emitting borate host phosphor YCaBO 4 : Eu 3+ has been prepared by a novel solution combustion technique. The synthesis is based on the exothermic reaction between the fuel (Urea) and Oxidizer (Ammonium nitrate). The photoluminescence properties of the powder samples of YCaBO 4 : Eu 3+ has been investigated under UV and VUV excitation. The phosphor shows strong absorption in UV and VUV region and exhibits intense red emission upon excited by 254 nm UV and 173 nm VUV radiation. Under UV 254 nm excitation, YCaBO 4 : Eu 3+ exhibits intense red emission around 610 nm. Under VUV excitation of 173 nm, the phosphor emits intense red emission around 610 nm and few weak emissions. These weak emissions could be suppressed by annealing the sample repeatedly at proper temperature and the borate phosphor YCaBO 4 : Eu 3+ could be a good red emitting phosphor for PDP display and mercury free lamps.

    2005-01-01

    The operon (cyo) encoding the Na + -pumping respiratory terminal oxidase (cytochrome bo) of the bacterium Vitreoscilla was transformed into Escherichia coli GV100, a deletion mutant of cytochrome bo. This was done for the wild type operon and five mutants in three conserved Cyo subunit I amino acids known to be crucial for H + transport in the E. coli enzyme, one near the nuclear center, one in the K-channel, and one in the D-channel. CO-binding, NADH and ubiquinol oxidase, and Na + -pumping activities were all substantially inhibited by each mutation. The wild type Vitreoscilla cytochrome bo can pump Na + against a concentration gradient, resulting in a transmembrane concentration differential of 2-3 orders of magnitude. It is proposed that Vitreoscilla cytochrome bo pumps four Na + through the D-channel to the exterior and transports four H + through the K-channel for the reduction of each O 2

  13. BoS: a large and diverse family of short interspersed elements (SINEs) in Brassica oleracea.

    Zhang, Xiaoyu; Wessler, Susan R

    2005-05-01

    Short interspersed elements (SINEs) are nonautonomous non-LTR retrotransposons that populate eukaryotic genomes. Numerous SINE families have been identified in animals, whereas only a few have been described in plants. Here we describe a new family of SINEs, named BoS, that is widespread in Brassicaceae and present at approximately 2000 copies in Brassica oleracea. In addition to sharing a modular structure and target site preference with previously described SINEs, BoS elements have several unusual features. First, the head regions of BoS RNAs can adopt a distinct hairpin-like secondary structure. Second, with 15 distinct subfamilies, BoS represents one of the most diverse SINE families described to date. Third, several of the subfamilies have a mosaic structure that has arisen through the exchange of sequences between existing subfamilies, possibly during retrotransposition. Analysis of BoS subfamilies indicate that they were active during various time periods through the evolution of Brassicaceae and that active elements may still reside in some Brassica species. As such, BoS elements may be a valuable tool as phylogenetic makers for resolving outstanding issues in the evolution of species in the Brassicaceae family.

    Full Text Available Abstract Background Ebola virus (EBOV is a Category A pathogen that is a member of Filoviridae family that causes hemorrhagic fever in humans and non-human primates. Unpredictable and devastating outbreaks of disease have recently occurred in Africa and current immunoprophylaxis and therapies are limited. The main limitation of working with pathogens like EBOV is the need for costly containment. To potentiate further and wider opportunity for EBOV prophylactics and therapies development, innovative approaches are necessary. Methods In the present study, an antigen delivery platform based on a recombinant bovine herpesvirus 4 (BoHV-4, delivering a synthetic EBOV glycoprotein (GP gene sequence, BoHV-4-syEBOVgD106ΔTK, was generated. Results EBOV GP was abundantly expressed by BoHV-4-syEBOVgD106ΔTK transduced cells without decreasing viral replication. BoHV-4-syEBOVgD106ΔTK immunized goats produced high titers of anti-EBOV GP antibodies and conferred a long lasting (up to 6 months, detectable antibody response. Furthermore, no evidence of BoHV-4-syEBOVgD106ΔTK viremia and secondary localization was detected in any of the immunized animals. Conclusions The BoHV-4-based vector approach described here, represents: an alternative antigen delivery system for vaccination and a proof of principle study for anti-EBOV antibodies generation in goats for potential immunotherapy applications.

  15. Wind power in France

    International Nuclear Information System (INIS)

    Tuille, F.; Courtel, J.

    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.)

  17. [Primary care in France].

    Sánchez-Sagrado, T

    2016-01-01

    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.)

    Highlights: • Spin-glass behavior of MgFeBO{sub 4} and CoFeBO{sub 4} observed by Mössbauer spectroscopy. • Transition temperature T{sub SG} increases strongly with Co substitution. • Dynamical scaling theory near T{sub SG} is fulfilled. • Spin-glass behavior is explained as due to short range correlations. • Inclusion of Co increases exchange interaction and magnetocrystalline anisotropy. - Abstract: Single crystals of MgFeBO{sub 4} and CoFeBO{sub 4} warwickites were obtained. The effects of charge ordering and magnetic properties were investigated by Mössbauer spectroscopy. Cation distribution over M1 and M2 nonequivalent sites and the average charge at the metal positions were established. Low temperature Mössbauer spectra reveal spin-glass behavior, with spin-freezing temperatures T{sub SG} of 15.2 and 33.2 K for Mg- and Co-warwickites, respectively, higher than that observed from the d.c. and a.c. magnetic susceptibility measurements. The difference is explained in terms of dynamical scaling theory. The specific shape of the Mössbauer spectra in the vicinity of the magnetic transition at T{sub SG} shows the difference between spin-glass and superparamagnetic behavior and demonstrates an overwhelming role of the exchange anisotropy in the properties of Mg-warwickite. In Co-warwickite the increase of magnetocrystalline anisotropy provokes an increase in magnetic viscosity.

    KBe 2 BO 3 F 2 (KBBF) is still the only practically usable crystal that can generate deep-ultraviolet (DUV) coherent light by direct second harmonic generation (SHG). However, applications are hindered by layering, leading to difficulty in the growth of thick crystals and compromised mechanical integrity. Despite efforts, it is still a great challenge to discover new nonlinear optical (NLO) materials that overcome the layering while keeping the DUV SHG available. Now, two new DUV NLO beryllium borates have been successfully designed and synthesized, NH 4 Be 2 BO 3 F 2 (ABBF) and γ-Be 2 BO 3 F (γ-BBF), which not only overcome the layering but also can be used as next-generation DUV NLO materials with the shortest type I phase-matching second-harmonic wavelength down to 173.9 nm and 146 nm, respectively. Significantly, γ-BBF is superior to KBBF in all metrics and would be the most outstanding DUV NLO crystal. © 2018 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim.

    Bovine herpesvirus types 1 (BoHV-1) and 5 (BoHV-5) are antigenically and genetically similar. The aim of this study was to develop a simple and reliable one-step real time PCR assay with high resolution melting (HRM) analysis for the simultaneous detection and differentiation of BoHV-1 and BoHV-5. Optimization of assay conditions was performed with DNA from reference strains. Then, DNA from field isolates, clinical samples and tissue samples of experimentally infected animals were studied by real time PCR-HRM. An efficient amplification of real time PCR products was obtained, and a clear melting curve and appropriate melting peaks for both viruses were achieved in the HRM curve analysis for BoHV type identification. BoHV was identified in all of the isolates and clinical samples, and BoHV types were properly differentiated. Furthermore, viral DNA was detected in 12/18 and 7/18 samples from BoHV-1- and BoHV-5-infected calves, respectively. Real time PCR-HRM achieved a higher sensitivity compared with virus isolation or conventional PCR. In this study, HRM was used as a novel procedure. This method provides rapid, sensitive, specific and simultaneous detection of bovine alpha-herpesviruses DNA. Thus, this technique is an excellent tool for diagnosis, research and epidemiological studies of these viruses in cattle. Copyright © 2015 Elsevier B.V. All rights reserved.

    1991-01-01

    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

  16. Identification and expression analysis of BoMF25, a novel polygalacturonase gene involved in pollen development of Brassica oleracea.

    BoMF25 acts on pollen wall. Polygalacturonase (PG) is a pectin-digesting enzyme involved in numerous plant developmental processes and is described to be of critical importance for pollen wall development. In the present study, a PG gene, BoMF25, was isolated from Brassica oleracea. BoMF25 is the homologous gene of At4g35670, a PG gene in Arabidopsis thaliana with a high expression level at the tricellular pollen stage. Collinear analysis revealed that the orthologous gene of BoMF25 in Brassica campestris (syn. B. rapa) genome was probably lost because of genome deletion and reshuffling. Sequence analysis indicated that BoMF25 contained four classical conserved domains (I, II, III, and IV) of PG protein. Homology and phylogenetic analyses showed that BoMF25 was clustered in Clade F. The putative promoter sequence, containing classical cis-acting elements and pollen-specific motifs, could drive green fluorescence protein expression in onion epidermal cells. Quantitative RT-PCR analysis suggested that BoMF25 was mainly expressed in the anther at the late stage of pollen development. In situ hybridization analysis also indicated that the strong and specific expression signal of BoMF25 existed in pollen grains at the mature pollen stage. Subcellular localization showed that the fluorescence signal was observed in the cell wall of onion epidermal cells, which suggested that BoMF25 may be a secreted protein localized in the pollen wall.

  17. BoALMT1, an Al-Induced Malate Transporter in Cabbage, Enhances Aluminum Tolerance in Arabidopsis thaliana

    Full Text Available Aluminum (Al is present in approximately 50% of the arable land worldwide and is regarded as the main limiting factor of crop yield on acidic soil. Al-induced root malate efflux plays an important role in the Al tolerance of plants. Here, the aluminum induced malate transporter BoALMT1 (KF322104 was cloned from cabbage (Brassica oleracea. BoALMT1 showed higher expression in roots than in shoots. The expression of BoALMT1 was specifically induced by Al treatment, but not the trivalent cations lanthanum (La, cadmium (Cd, zinc (Zn, or copper (Cu. Subcellular localization studies were performed in onion epidermal cells and revealed that BoALMT1 was localized at the plasma membrane. Scanning Ion-selective Electrode Technique was used to analyze H+ flux. Xenopus oocytes and Arabidopsis thaliana expressing BoALMT1 excreted more H+ under Al treatment. Overexpressing BoALMT1 in transgenic Arabidopsis resulted in enhanced Al tolerance and increased malate secretion. The results suggested that BoALMT1 functions as an Al-resistant gene and encodes a malate transporter. Expressing BoALMT1 in Xenopus oocytes or A. thaliana indicated that BoALMT1 could increase malate secretion and H+ efflux to resist Al tolerance.

    Full Text Available Abstract The significant effect of the feeding mode on the morphology and size distribution of the hydrothermal synthesized MgBO2(OH is investigated, which indicates that, slow dropping rate (0.5 drop s−1 and small droplet size (0.02 mL d−1 of the dropwise added NaOH solution are favorable for promoting the one-dimensional (1D preferential growth and thus enlarging the aspect ratio of the 1D MgBO2(OH nanostructures. The joint effect of the low concentration of the reactants and feeding mode on the hydrothermal product results in the head-to-head coalesced MgBO2(OH nanowires with a length of 0.5–9.0 μm, a diameter of 20–70 nm, and an aspect ratio of 20–300 in absence of any capping reagents/surfactants or seeds.

    2006-01-01

    The conserved Glu540 in subunit I of Escherichia coli cytochrome bo (a H + pump) is replaced by Asp544 in the Vitreoscilla enzyme (a Na + pump). Site-directed mutagenesis of the Vitreoscilla cytochrome bo operon changed this Asp to Glu, and both wild type and mutant cyo's were transformed into E. coli strain GV100, which lacks cytochrome bo. Compared to the wild type transformant the Asp544Glu transformant had decreased ability to pump Na + as well as decreased stimulation in respiratory activity in the presence of Na + . Preliminary experiments indicated that this mutant also had increased ability to pump protons, suggesting that this single change may provide cation pumping specificity in this group of enzymes

    2015-01-01

    In agricultural species that are sexually propagated or whose marketable organ is a reproductive structure, management of the flowering process is critical. Inflorescence development in cauliflower is particularly complex, presenting unique challenges for those seeking to predict and manage flowering time. In this study, an integrated physiological and molecular approach was used to clarify the environmental control of cauliflower reproductive development at the molecular level. A functional allele of BoFLC2 was identified for the first time in an annual brassica, along with an allele disrupted by a frameshift mutation (boflc2). In a segregating F₂ population derived from a cross between late-flowering (BoFLC2) and early-flowering (boflc2) lines, this gene behaved in a dosage-dependent manner and accounted for up to 65% of flowering time variation. Transcription of BoFLC genes was reduced by vernalization, with the floral integrator BoFT responding inversely. Overall expression of BoFT was significantly higher in early-flowering boflc2 lines, supporting the idea that BoFLC2 plays a key role in maintaining the vegetative state. A homologue of Arabidopsis VIN3 was isolated for the first time in a brassica crop species and was up-regulated by two days of vernalization, in contrast to findings in Arabidopsis where prolonged exposure to cold was required to elicit up-regulation. The correlations observed between gene expression and flowering time in controlled-environment experiments were validated with gene expression analyses of cauliflowers grown outdoors under 'natural' vernalizing conditions, indicating potential for transcript levels of flowering genes to form the basis of predictive assays for curd initiation and flowering time. © The Author 2014.

    Botulinum neurotoxins (BoNTs) are produced by various species of clostridia and are potent neurotoxins which cause the disease botulism, by cleaving proteins needed for successful nerve transmission. There are currently seven confirmed serotypes of BoNTs, labeled A-G, and toxin-producing clostridia typically only produce one serotype of BoNT. There are a few strains (bivalent strains) which are known to produce more than one serotype of BoNT, producing either both BoNT/A and /B, BoNT/A and /F, or BoNT/B and /F, designated as Ab, Ba, Af, or Bf. Recently, it was reported that Clostridium botulinum strain Af84 has three neurotoxin gene clusters: bont/A2, bont/F4, and bont/F5. This was the first report of a clostridial organism containing more than two neurotoxin gene clusters. Using a mass spectrometry based proteomics approach, we report here that all three neurotoxins, BoNT/A2, /F4, and /F5, are produced by C. botulinum Af84. Label free MS(E) quantification of the three toxins indicated that toxin composition is 88% BoNT/A2, 1% BoNT/F4, and 11% BoNT/F5. The enzymatic activity of all three neurotoxins was assessed by examining the enzymatic activity of the neurotoxins upon peptide substrates, which mimic the toxins' natural targets, and monitoring cleavage of the substrates by mass spectrometry. We determined that all three neurotoxins are enzymatically active. This is the first report of three enzymatically active neurotoxins produced in a single strain of Clostridium botulinum.

    1972-07-01

    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.

  16. Shielding research in France

    Energy Technology Data Exchange (ETDEWEB)

    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

    Highlights: ► GdBO 3 :Ln 3+ nanofibers were synthesized successfully by electrospinning. ► The samples have the average diameter of 150 nm and the flexible morphology. ► The GdBO 3 : Eu 3+ nanofibers have the stronger orange emission. ► The luminescence properties are different from the reported bulk material. ► We describe the energy transform process of GdBO 3 :Ln 3+ system. - Abstract: GdBO 3 :Ln 3+ (Ln = Eu, Tb) nanofibers were synthesized using electrospinning combined with heat treatment. The synthesized nanofibers were characterized by X-ray diffraction, Raman spectroscopy, field emission-scanning electron microscopy, thermogravimetric and differential thermal analyses, and photoluminescence. The experimental results show that the flexible synthesized nanofibers have an average diameter of approximately 150 nm. The nanofibers consist of crystalline grains with diameters of about 40 nm and have a vaterite-type structure of GdBO 3 . The GdBO 3 :Eu 3+ nanofibers exhibit strong orange and weak red emissions with a low ratio of red to orange emission intensities, which is different from those of the reported bulk materials and nanoparticles. The luminescence properties of the synthesized GdBO 3 :Tb 3+ nanofibers are essentially consistent with those of the synthesized GdBO 3 :Tb 3+ powders by solid-state reaction.

    In this work, the optimization of the geometry and the electronic properties of the host matrix KMgBO{sub 3} were investigated using density functional theory, and the comprehensive photoluminescence and chromaticity properties on five rare earth ion-doped (RE = Ce{sup 3+}, Tm{sup 3+}, Tb{sup 3+}, Eu{sup 3+}, Dy{sup 3+}) KMgBO{sub 3} phosphors were also studied. By introducing RE ions into the KMgBO{sub 3} host, excellent purple, blue, green, red and white emitting light could be obtained under the near-ultraviolet light excitation. The results suggest that rare earth doped KMgBO{sub 3} phosphors are potential luminescence materials for the application in the near-ultraviolet white light-emitting diodes. - Highlights: • The electronic properties of the host matrix KMgBO{sub 3} were investigated. • The PL properties on rare earth ions doped KMgBO{sub 3} phosphors were studied. • The chromaticity properties on rare earth ions doped KMgBO{sub 3} samples were studied. • Tm{sup 3+} and Eu{sup 3+} doped KMgBO{sub 3} samples show higher color purity than commercial phosphors.

    One of the main chemical forms of cesium in the gas phase during severe light-water reactor accidents is expected to be cesium metaborate, CsBO2, according to thermodynamic equilibrium calculations considering its reaction with boron. However, the accuracy of the thermodynamic data of the gaseous metaborate, CsBO2(g), has been judged as poor. Thus, Knudsen effusion mass spectrometric measurements of CsBO2 were carried out to obtain reliable thermodynamic data. The evaluated values of the standard enthalpy of formation of CsBO2(g), obtained by the 2nd and 3rd-law treatments, are -700.7 ± 10.7 kJ/mol and -697.0 ± 10.6 kJ/mol, respectively, and agree with each other within the experimental errors, which indicates that our data are reliable. Furthermore, it was found that the existing data of the Gibbs energy function and the standard enthalpy of formation agreed well with the values evaluated in this study, which indicates that the existing thermodynamic data are also reliable.

    Interferon-τ (IFN-τ) signals pregnancy recognition in ruminants. We investigated the effects of IFN-τ produced by embryo trophoblastic cells (ETCs) on expression of bovine leukocyte antigen-I (BoLA-I), a bovine analogue of human MHC-I, in endometrial luminal epithelial cells (EECs) during early pregnancy in dairy cows. Expression of IFN-τ and BoLA-I was increased in endometrial tissues during early pregnancy. Expression of the anti-inflammatory cytokine IL-10 was increased in endometrial tissues, while expression of the pro-inflammatory cytokine IL-6 was decreased, indicating immunosuppression. Progesterone increased IFN-τ expression in EECs. IFN-τ increased p-STAT1 and p-STAT3 levels in EECs, but reduced TRAF3 levels. In addition, IFN-τ increased expression of BoLA-I and IL-10, but decreased expression of IL-6 in EECs. These results indicate that IFN-τ enables stable implantation in dairy cows by increasing expression of BoLA-I, and by immunosuppression mediated by increased IL-10 and decreased IL-6 expression.

    Full Text Available In March 2007 the sea floor drill rig MeBo (short for “Meeresboden-Bohrgerät”, ‘sea floor drill rig’ in German returned from a 17-day scientific cruise with the new German research vessel Maria S. Merian. Four sites between 350 m and 1700 m water depth were sampled at the continental slope off Morocco by push coring and rotary drilling. Up to 41.5-m-long sediment cores were recovered from Miocene, Pliocene, and Pleistocene marls. MeBo bridges the gapbetween conventional sampling methods from standard multipurpose research vessels (gravity corer, piston corer, dredges and drill ships. Most bigger research vessels will be able to support deployment of the MeBo. Since the drill system can be easily transported within 20-ft containers, worldwide operation from vessels of opportunity is possible. With the MeBo a new system is available for marine geosciences that allows the recovery of high quality samples from soft sediments and hard rock from the deep sea withoutrelying on the services of expensive drilling vessels.

  11. Characterization of the regulatory network of BoMYB2 in controlling anthocyanin biosynthesis in purple cauliflower.

    Science.gov (United States)

    Chiu, Li-Wei; Li, Li

    2012-10-01

    Purple cauliflower (Brassica oleracea L. var. botrytis) Graffiti represents a unique mutant in conferring ectopic anthocyanin biosynthesis, which is caused by the tissue-specific activation of BoMYB2, an ortholog of Arabidopsis PAP2 or MYB113. To gain a better understanding of the regulatory network of anthocyanin biosynthesis, we investigated the interaction among cauliflower MYB-bHLH-WD40 network proteins and examined the interplay of BoMYB2 with various bHLH transcription factors in planta. Yeast two-hybrid studies revealed that cauliflower BoMYBs along with the other regulators formed the MYB-bHLH-WD40 complexes and BobHLH1 acted as a bridge between BoMYB and BoWD40-1 proteins. Different BoMYBs exhibited different binding activity to BobHLH1. Examination of the BoMYB2 transgenic lines in Arabidopsis bHLH mutant backgrounds demonstrated that TT8, EGL3, and GL3 were all involved in the BoMYB2-mediated anthocyanin biosynthesis. Expression of BoMYB2 in Arabidopsis caused up-regulation of AtTT8 and AtEGL3 as well as a subset of anthocyanin structural genes encoding flavonoid 3'-hydroxylase, dihydroflavonol 4-reductase, and leucoanthocyanidin dioxygenase. Taken together, our results show that MYB-bHLH-WD40 network transcription factors regulated the bHLH gene expression, which may represent a critical feature in the control of anthocyanin biosynthesis. BoMYB2 together with various BobHLHs specifically regulated the late anthocyanin biosynthetic pathway genes for anthocyanin biosynthesis. Our findings provide additional information for the complicated regulatory network of anthocyanin biosynthesis and the transcriptional regulation of transcription factors in vegetable crops.

    2015-01-01

    Sphere-like and cauliflower-like hexagonal-vaterite LuBO 3 have been successfully synthesized for the first time via a chemical conversion route using Lu(OH)CO 3 colloid spheres as sacrificial precursor and H 3 BO 3 as boron source without any additional surfactant. FTIR analysis provides an additional evidence of the formation of vaterite-type LuBO 3 in this method. It was found that, an appropriate amount ethanol in the hydrothermal process has a great effect on the products' morphology and crystallinity. Time-dependent experiments indicate that the formation of LuBO 3 crystals went through a two-stage growth process, which involves a fast nucleation of primary particles followed by a slow aggregation and crystallization of primary particles. An investigation on the photoluminescence (PL) properties of LuBO 3 :Eu 3+ phosphors with different morphologies indicates that their PL intensity are dependent on their crystallinity. The effect of Eu 3+ and Tb 3+ doping concentration on PL intensity were also investigated and the quenching concentration of LuBO 3 :Eu 3+ and LuBO 3 :Tb 3+ is 0.25 and 0.20, respectively. Moreover, for Eu 3+ /Tb 3+ doped LuBO 3 phosphors, the color tones can be tuned from green, through green–yellow and yellow, and then to red by simply adjusting the relative doping concentrations of the Tb 3+ and Eu 3+ ions. - Highlights: • Sphere-like and cauliflower-like LuBO 3 were obtained by a conversion route. • This method used Lu(OH)CO 3 and H 3 BO 3 as the precursors for the first time. • Ethanol can control the products' morphology, crystallinity and PL intensity. • The emitting color tones vary with Tb 3+ /Eu 3+ doped concentration

    2018-01-01

    Ce3+ or Yb3+ singly doped LaBO3 and Ce3+-Yb3+ co-doped LaBO3 were prepared by conventional solid state reactions at 1100 °C and their photoluminescence (PL) properties were investigated. The emission spectrum of LaBO3:Ce3+,Yb3+ contains both the Ce3+ ultraviolet (UV) emissions (355 nm and 380 nm) and the Yb3+ near infrared (NIR) emission (975 nm) when excited by the UV light at 270 nm. By using the data of the Ce3+ decay curves and the PL intensities of both Ce3+ and Yb3+, the energy transfer efficiency (η) from Ce3+ to Yb3+, the actual energy transfer efficiency (AE) and the quantum efficiency (Q) of the Yb3+ emission were calculated. In the Ce3+-Yb3+ co-doped LaBO3, Ce3+ can transfer its absorbed energy to Yb3+ efficiently (η can be over 60%), and Yb3+ shows the Q value over 50% when it accepts the energy from Ce3+, which results in the low AE value ∼30%. The energy transfer process from Ce3+ to Yb3+ may be understood by the charge transfer mechanism: Ce3+ + Yb3+ ↔ Ce4+ + Yb2+. Particularly the Ce3+-Yb3+ co-doped LaBO3 phosphor gives the emissions mainly in the UV range and the NIR range with a portion of visible emissions in eye-insensitive range. This unique property may be suitable for applications in anti-counterfeiting techniques and public security affairs.

  15. France looks to biomass

    Energy Technology Data Exchange (ETDEWEB)

    1982-03-22

    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

  17. Nuclear safety in France

    International Nuclear Information System (INIS)

    Laverie, M.

    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

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

  1. Accident response in France

    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

    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.

    High-pressure Raman scattering studies revealed that BaHf(BO{sub 3}){sub 2} is more compressible than calcite-type orthoborates and calcite, aragonite or dolomite carbonates. It undergoes a first-order reversible pressure-induced phase transition in the 3.9–4.4 GPa pressure range. Second structural change is observed at 9.2 GPa. The intermediate phase is most likely trigonal. However, Raman results suggest increase in the number of distinct BO{sub 3} groups from two in the ambient pressure phase to at least three in the intermediate phase. This intermediate phase is also strongly compressible and strong pressure dependence of the lattice modes proves that the main changes under pressure occur within the layers built from BaO{sub 6} and HfO{sub 6} octahedra. The second phase transition leads most likely to lowering of the trigonal symmetry, as evidenced by significant increase of the number of observed bands. The pressure coefficients of the Raman bands of the high-pressure phase are relatively small, suggesting more dense arrangement of the metal–oxygen polyhedra and BO{sub 3} groups in this phase. It is worth noting that the high-pressure phase was not reached in the second compression experiment up to 10 GPa. This behavior can be most likely attributed to worse hydrostatic conditions of the first experiment. - Graphical abstract: Raman spectra of BaHf(BO{sub 3}){sub 2} recorded at different pressures during compression showing onset of pressure-induced phase transitions. - Highlights: • High-pressure Raman spectra were measured for BaHf(BO{sub 3}){sub 2.} • BaHf(BO{sub 3}){sub 2} undergoes a reversible first-order phase transition at 3.9–4.4 GPa into a trigonal phase. • The intermediate trigonal phase is strongly compressible second structural transformation is observed at 9.2 GPa under non-perfect hydrostatic conditions.

  14. 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

    Bovine herpesvirus 4 (BoHV-4) has been isolated from cattle with respiratory infections, vulvovaginitis, mastitis, abortions, endometritis and from apparently healthy animals throughout the world. Although it has not yet been established as causal agent of a specific disease entity, it is primarily associated with reproductive disorders of cattle. This virus can infect a wide range of species, either in vivo or in vitro. Two groups of prototype strains were originated from the first isolates: the DN599-type strains (American group) and the Movar-type strains (European group). In Argentina, BoHV-4 was isolated and characterized in 2007 from vaginal discharge samples taken from cows that had aborted. So far, more than 40 isolates, mainly associated with aborting bovine females have been registered in our country. Copyright © 2014 Asociación Argentina de Microbiología.

    With the help of low-symmetry mechanical stresses, we induced an additional spatially inhomogeneous anisotropy in the basal plane of a single crystal FeBO 3 . By the magnetooptical method, we study the effect of an inhomogeneous magnetic anisotropy on the magnetic state of this easy-plane weak ferromagnetic. It is established that, at the magnetization of inhomogeneously stressed FeBO 3 in the basal plane near some separated direction, the crystal transits from the homogeneous state into a spatially modulated magnetic state. The latter can be represented in the form of a static spin wave, in which a local vector of ferromagnetism oscillates near the direction of the mean magnetization of a crystal, by remaining in the basal plane.

    2015-01-01

    Yersinia enterocolitica was isolated from 15.7% (88/560) of wild rodents captured in 15 prefectures in Japan. Prevalences by rodent species were 18.0% (70/388) in Japanese field mice (Apodemus speciosus), 20% (14/71) in small Japanese field mice (Apodemus argenteus), and 11% (4/38) in gray red-backed vole (Myodes rufocanus bedfordiae), suggesting that these rodent species are important reservoirs of Y. enterocolitica. Although most of the isolates were identified as biotype 1A, the pathogenic bioserotype 1B/O:8 was detected in one of the A. speciosus and in three of the A. argenteus captured in Aomori Prefecture. It is suggested that Apodemus mice may be an important reservoir of Y. enterocolitica, and that there are foci of the pathogenic bioserotype 1B/O:8 in Aomori Prefecture, because human sporadic cases by the serotype have been reported in this prefecture.

    Full Text Available Botulinum neurotoxins (BoNTs, etiological agents of the life threatening neuroparalytic disease botulism, are the most toxic substances currently known. The potential for the use as bioweapon makes the development of small-molecule inhibitor against these deadly toxins is a top priority. Currently, there are no approved pharmacological treatments for BoNT intoxication. Although an effective vaccine/immunotherapy is available for immuno-prophylaxis but this cannot reverse the effects of toxin inside neurons. A small-molecule pharmacological intervention, especially one that would be effective against the light chain protease, would be highly desirable. Similarity search was carried out from ChemBridge and NSC libraries to the hit (7-(phenyl(8-quinolinylaminomethyl-8-quinolinol; NSC 84096 to mine its analogs. Several hits obtained were screened for in silico inhibition using AutoDock 4.1 and 19 new molecules selected based on binding energy and Ki. Among these, eleven quinolinol derivatives potently inhibited in vitro endopeptidase activity of botulinum neurotoxin type A light chain (rBoNT/A-LC on synaptosomes isolated from rat brain which simulate the in vivo system. Five of these inhibitor molecules exhibited IC(50 values ranging from 3.0 nM to 10.0 µM. NSC 84087 is the most potent inhibitor reported so far, found to be a promising lead for therapeutic development, as it exhibits no toxicity, and is able to protect animals from pre and post challenge of botulinum neurotoxin type A (BoNT/A.

    Full Text Available In the present investigation, a facile synthesis method is explored involving a self-combustion of a solid precursor mixture of iron oxide Fe2O3 and boric acid (H3BO3 using camphor (C10H16O as fuel in ambient air in order to form a single phase Fe3BO6 crystallites. X-ray diffraction (XRD, Field emission electron microscopy (FESEM, magnetic, and dielectric properties of as prepared sample are studied. From XRD pattern, a single phase compound is observed with an orthorhombic crystal structure (Pnma space group, with average crystallite size of 42nm. A reasonably uniform size distribution of the plates and self-assemblies is retained in the sample. A magnetic transition is observed in dielectric permittivity (at ∼445K and power loss (at ∼435K when plotted against temperature. A weak peak occurs near 330K due to the charge reordering in the sample. For temperatures above the transition temperature, a sharp increase of the dielectric loss is observed which occurs due to the presence of thermally activated charge carriers. A canted antiferromagnetic Fe3+ ordering in a Fe3BO6 lattice with a localized charge surface layer is an apparent source of exhibiting a ferroelectric feature in this unique example of a centrosymmetric compound. An induced spin current over the Fe sites thus could give rise to a polarization hysteresis loop. Due to the presence of both ferromagnetic as well as polarization ordering, Fe3BO6 behaves like a single phase multiferroic ceramics.

    Crystals of a new polar borate Na{sub 2}Ce{sub 2}[BO{sub 2}(OH)][BO{sub 3}]{sub 2} · H{sub 2}O were prepared by hydrothermal synthesis. The crystals are orthorhombic, a = 7.2295(7) Å, b = 11.2523(8) Å, c = 5.1285(6) Å, Z = 2, sp. gr. C2mm (Amm2), R = 0.0253. The formula of the compound was derived from the structure determination. The Ce and Na atoms are coordinated by nine and six O atoms, respectively. The Ce position is split, and a small amount of Ce is incorporated into the Na1 site with the isomorphous substitution for Na. The anionic moieties exist as isolated BO{sub 3} and BO{sub 2}(OH) triangles. The planes of the BO{sub 2}(OH) triangles with mm2 symmetry are parallel to the ab plane. The planes of the BO{sub 3} triangles with m symmetry are perpendicular to the ab plane and are rotated in a diagonal way. The splitting of the Ce positions and the polar arrangement of the BO{sub 2}(OH) triangles, water molecules, and Na atoms are observed along the polar a axis. The new structure is most similar to the new borate NaCa{sub 4}[BO{sub 3}]{sub 3} (sp. gr. Ama2), in which triangles of one type are arranged in a polar fashion along the c axis. Weak nonlinear-optical properties of both polar borates are attributed to the quenching of the second-harmonic generation due to the mutually opposite orientation of two-thirds of B triangles in the unit cell.

    Highlights: • A Yb 3+ :Sr 3 Y 2 (BO 3 ) 4 crystal was grown successfully by Czochralski method. • The crystal has wide absorption and emission bandwidth. • 3.47 W continuous wave laser output with a slope efficiency of 29% was obtained. • The results show that the crystal is a promising ultrashort pulse laser material. - Abstract: A Yb 3+ :Sr 3 Y 2 (BO 3 ) 4 crystal was grown successfully by the Czochralski method. The polarized spectral properties and continuous wave laser output of this crystal were investigated in detail. The crystal has larger absorption and emission cross sections compared with many mature Yb 3+ -doped borate crystals. The full width at half maximum of the emission bands around 1023 nm are 69 nm (E//a), 61 nm (E//b) and 65 nm (E//c). 3.47 W continuous wave laser output with a slope efficiency of 29% and an optical conversion efficiency of 24% was obtained. The results reveal that Yb 3+ :Sr 3 Y 2 (BO 3 ) 4 crystal is an excellent candidate for ultrashort pulse laser crystal

    The magnetic structure of a Fe 3 BO 6 crystal belonging to space group Dsub(2h)sup(16)(Psub(nma)) is determined by the Moessbauer γ-radiation diffraction. The bragg reflection (700) of Moessbauer 14.4 keV γ-quanta from the Fe 3 BO 6 monocrystal has been studied experimentally. A high sensitivity of the interference of γ-quantum diffraction scattering on Fe nuclei being in crystallographically non-equivalent 8d- and 4s-positions to the type of magnetic ordering in the crystal is used for determination of the magnetic structure. Agreement of the experimental results with the theoretical calculations, conducted for types of magnetic ordering resolved by the symmetry of the crystal, permitted to reliably determine the magnetic structure of this compound. The results obtained confirm the data of neutrondiffraction studies on magnetic ordering in Fe 3 BO 6 . Advantages of the Moessbauer-diffraction study, as compared to the magnetic neutrondiffraction method, in particular, for investigation of crystals, in which the hyperfine magnetic fields on Fe nuclei have different values, are revealed and discussed in detail

    To construct secondary mutant phage-display library of recombinant single variable domain (VHH) against botulinum neurotoxin E by error-prone PCR. The gene coding for specific VHH derived from the camel immunized with binding domain of botulinum neurotoxin E (BoNT/E) was amplified by error-prone PCR. Several biopanning rounds were used to screen the phage-displaying BoNT/E Hc nanobodies. The final nanobody, SHMR4, with increased affinity recognized BoNT/E toxin with no cross-reactivity with other antigens especially with related BoNT toxins. The constructed nanobody could be a suitable candidate for VHH-based biosensor production to detect the Clostridium botulinum type E. Diagnosis and treatment of botulinum neurotoxins are important. Generation of high-affinity antibodies based on the construction of secondary libraries using affinity maturation step leads to the development of reagents for precise diagnosis and therapy. © 2014 The Society for Applied Microbiology.

    The associations between BoLA class I haplotypes and subclinical mastitis were investigated using information on 333 cows from three different breeds and crossbreeds from 14 dairy herds in Denmark. Somatic cell count and bacteriological status were used as markers for subclinical mastitis....... Associations between BoLA class I haplotypes and IMI status were also determined. The association between BoLA class I haplotypes and subclinical mastitis was weak. The A10(W50), A11, A12(A30), A16, A19(A6), A21, A26, and A31(A30) alleles were associated with different markers of subclinical mastitis....... Susceptibility or resistance to the two bacteria categories was associated with different alleles. This study indicated that BoLA antigens may be involved in resistance to mastitis and that resistance may be specific for a particular pathogen....

    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.

    Full text: The title compounds are now intensively studied due to their quadratic nonlinear properties in view of applications, e.g. high power laser frequency conversion. Rare earth calcium oxoborates, Ca 4 REO(BO 3 ) 3 , constitute an isostructural family along the rare earth series with RE = La - Lu, Y included. These compounds crystallize in the monoclinic biaxial crystal system with Cm (N 8) space group. They are isostructural to the calcium fluoroborate Ca 5 (BO 3 ) 3 F which is related to the fluoroapatite structure Ca 5 (PO 4 ) 3 F. The rare earth ions are located in the distorted octahedron with C s point site symmetry in the mirror plane. Two types of distorted octahedral sites exist for calcium ions. The existence of some disorder between calcium and rare earth atoms is suspected from the structural analysis. Good optical quality crystals of europium (or gadolinium) oxoborate, EuCOB (GdCOB) have been grown from the stoichiometric melt by the Czochralski pulling method. From the luminescence of the Eu 3+ doped gadolinium or in the europium stoichiometric compound very complex emission spectra have been obtained. It principally depends on the preparation method of studied samples: i) for a monocrystalline sample, a single phase with a single site is observed; ii) for a polycrystalline sample complex feature occurs. It is probably due to an expanded disorder between calcium and rare earth atoms. Practically, there is one principal site corresponding to the low symmetry site of the rare earth as expected from the structural investigation. Other minor sites are attributed to the local distortion created around the active rare earth ion. The intensity of the emission lines of Eu 3+ used as a local structural probe related to these minor sites increases when the gadolinium in Ca 4 GdO(BO 0 ) 3 is substituted by lanthanum or yttrium ions. It seems therefore evident that the synthesis of these rare earth calcium oxoborates must be realised carefully. The crystal

    From a sample of 119 Friesian calves, serologically typed for BoLA class I, 47 subjects were chosen expressing 9 different MHC types (A6, A6.9, A10, A11, A14, A15, A30, W16, M103) with the same age and reared in the same farm conditions. The animals were s.c. injected with a water in oil suspension of killed M. bovis and the treatment was repeated two days later. Before the treatment and 21 days later, calves were bled and on PBM (peripheral blood mononuclear leucocytes) were performed the following tests: 1. Lymphocyte Stimulation with bovine and avian PPDs (Purified protein derivative of Mycobacterium bovis and Mycobacterium avium, respectively). 2. Phagocytic activity towards M. bovis. 3. Class II molecules expression on cell surface. 4. Percentage of leucocyte populations and subpopulations. In the in vitro Lymphocyte Stimulation test, all the animals and classes were responders. Animals bearing A10 BoLA class I presented c.p.m. (counts per minute) and index values higher than the other cattle; these values were significantly positively related both to bovine and avian PPDs (P celular de moleculas de clase II. 4. Porcentaje de poblaciones y de subpob-laciones de leucocitos. Todos los animales y todos los tipos de MHC dieron respuestas positivas en las pruebas de Stimulacion Lymphocitaria. Los animales que tenian la BoLA A10 presentaron valores de c.p.m. y indices mas altos de los demas animales. Estos valores se encontraron significativamente y positivamente relacionados sea a la PPD bovina que a la PPD avicola. Por medio de la analisis de varianzas se encontro que el tipo BoLA A14 muestraba una correlacion significativa y algo positiva con una mejor actividad fagocitaria. Los tipos de clase BoLA I no parecieron que influenzaran de manera appreciable el porcentaje de positividad por la clase II y el porcentaje de leucocitos en la sangre PBM. 1993 Blackwell Verlag GmbH.

    Research highlights: → Novel blue emitting phosphors borate MSr 4 (BO 3 ) 3 (M = Li or Na) were prepared first. → Luminescent properties of phosphors borate MSr 4 (BO 3 ) 3 (M = Li or Na) were investigated extensively as candidates of blue emitting phosphor used for UV excited LED. → The optimal concentrations of dopant Ce 3+ ions in compound MSr 4 (BO 3 ) 3 (M = Li or Na) were determined as 0.05 for Li and x = 0.09 for Na excited by UV light respectively. - Abstract: A series of Ce 3+ doped novel borate phosphors MSr 4 (BO 3 ) 3 (M = Li or Na) were successfully synthesized by traditional solid-state reaction. The crystal structures and the phase purities of samples were characterized by powder X-ray diffraction. The optimal concentrations of dopant Ce 3+ ions in compound MSr 4 (BO 3 ) 3 (M = Li or Na) were determined through the measurements of photoluminescence spectra of phosphors. Ce 3+ doped phosphors MSr 4 (BO 3 ) 3 (M = Li or Na) show strong broad band absorption in UV spectral region and bright blue emission under the excitation of 345 nm light. In addition, the temperature dependences of emission spectra of M 1+x Sr 4-2x Ce x (BO 3 ) 3 (M = Li or Na) phosphors with optimal composition x = 0.05 for Li and x = 0.09 for Na excited under 355 nm pulse laser were also investigated. The experimental results indicate that the M 1+x Sr 4-2x Ce x (BO 3 ) 3 (M = Li or Na) phosphors are promising blue emitting phosphors pumped by UV light.

    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

    Full Text Available Botulinum neurotoxin A (BoNT/A, the most acutely poisonous substance to humans known, cleave its SNAP-25 substrate with high specificity. Based on the endopeptidase activity, different methods have been developed to detect BoNT/A, but most lack ideal reproducibility or sensitivity, or suffer from long-term or unwanted interferences. In this study, we developed a simple method to detect and quantitate trace amounts of botulinum neurotoxin A using the IgY antibody against a linear-peptide substrate. The effects of reaction buffer, time, and temperature were analyzed and optimized. When the optimized assay was used to detect BoNT/A, the limit of detection of the assay was 0.01 mouse LD50 (0.04 pg, and the limit of quantitation was 0.12 mouse LD50/ml (0.48 pg. The findings also showed favorable specificity of detecting BoNT/A. When used to detect BoNT/A in milk or human serum, the proposed assay exhibited good quantitative accuracy (88% < recovery < 111%; inter- and intra-assay CVs < 18%. This method of detection took less than 3 h to complete, indicating that it can be a valuable method of detecting BoNT/A in food or clinical diagnosis.

    A novel and highly effective source of anthracnose resistance in narrow-leafed lupin was identified. Resistance was shown to be governed by a single dominant locus. Molecular markers have been developed, which can be used for selecting resistant genotypes in lupin breeding. A screening for anthracnose resistance of a set of plant genetic resources of narrow-leafed lupin (Lupinus angustifolius L.) identified the breeding line Bo7212 as being highly resistant to anthracnose (Colletotrichum lupini). Segregation analysis indicated that the resistance of Bo7212 is inherited by a single dominant locus. The corresponding resistance gene was given the designation LanrBo. Previously published molecular anchor markers allowed us to locate LanrBo on linkage group NLL-11 of narrow-leafed lupin. Using information from RNAseq data obtained with inoculated resistant vs. susceptible lupin entries as well as EST-sequence information from the model genome Lotus japonicus, additional SNP and EST markers linked to LanrBo were derived. A bracket of two LanrBo-flanking markers allows for precise marker-assisted selection of the novel resistance gene in narrow-leafed lupin breeding programs.

    A second botulism outbreak due to Clostridium baratii occurred in France in August 2015 and included three patients who had their meal in a restaurant the same day. We report the characterization of C. baratii isolates including whole genome sequencing (WGS). Four C. baratii isolates collected in August 2015 from the outbreak 2 were analysed for toxin production and typing as well as for genetic characterization. WGS was done using using the NEBNext Ultra DNA Library Prep kit for Illumina (New England Biolabs) and sequenced on MiSeq machine (Illumina) in paired-end reads of 250 bases. The phylogenetic tree was generated based on the UPGMA method with genetic distances computed by using the Kimura two-parameter model. Evolutionary analyses were conducted in Bionumerics (V.6.6 Applied Maths). Three C. baratii isolates for patient's stools and one isolate from meat produced botulinum neurotoxin (BoNT) type F and retained a bont/F7 gene in OrfX cluster. All isolates were identical according to the WGS. However, phylogeny of the core genome showed that the four C. baratii strains were distantly related to that of the previous C. baratii outbreak in France in 2014 and from the other C. baratii strains reported in databanks. The fact that the strains isolated from the patients and meat samples were genetically identical supports that the meat used for the Bolognese sauce was responsible for this second botulism outbreak in France. These isolates were unrelated to that from the first C. baratii outbreak in France in 2014 indicating a distinct source of contamination. WGS provided robust determination of genetic relatedness and information regarding BoNT typing and toxin gene locus genomic localization.

    2015-06-01

    Full Text Available Monkeypox virus (MPXV is the etiological agent of human (MPX. It is an emerging orthopoxvirus zoonosis in the tropical rain forest of Africa and is endemic in the Congo-basin and sporadic in West Africa; it remains a tropical neglected disease of persons in impoverished rural areas. Interaction of the human population with wildlife increases human infection with MPX virus (MPXV, and infection from human to human is possible. Smallpox vaccination provides good cross-protection against MPX; however, the vaccination campaign ended in Africa in 1980, meaning that a large proportion of the population is currently unprotected against MPXV infection. Disease control hinges on deterring zoonotic exposure to the virus and, barring that, interrupting person-to-person spread. However, there are no FDA-approved therapies against MPX, and current vaccines are limited due to safety concerns. For this reason, new studies on pathogenesis, prophylaxis and therapeutics are still of great interest, not only for the scientific community but also for the governments concerned that MPXV could be used as a bioterror agent. In the present study, a new vaccination strategy approach based on three recombinant bovine herpesvirus 4 (BoHV-4 vectors, each expressing different MPXV glycoproteins, A29L, M1R and B6R were investigated in terms of protection from a lethal MPXV challenge in STAT1 knockout mice. BoHV-4-A-CMV-A29LgD106ΔTK, BoHV-4-A-EF1α-M1RgD106ΔTK and BoHV-4-A-EF1α-B6RgD106ΔTK were successfully constructed by recombineering, and their capacity to express their transgene was demonstrated. A small challenge study was performed, and all three recombinant BoHV-4 appeared safe (no weight-loss or obvious adverse events following intraperitoneal administration. Further, BoHV-4-A-EF1α-M1RgD106ΔTK alone or in combination with BoHV-4-A-CMV-A29LgD106ΔTK and BoHV-4-A-EF1α-B6RgD106ΔTK, was shown to be able to protect, 100% alone and 80% in combination, STAT1(-/- mice

  12. 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

    Full Text Available Bovine herpes virus 1 (BoHV-1 is an important veterinary agent , which causes infectious bovine rhinotra-cheitis. This disease affects the respiratory tract or genitals, causing weight loss, reduced milk production and abor-tion. Several vaccines against BoHV-1 have been developed. In this paper, we study the parameters for MDBK growth on microcarriers (Cytodex 1 and for BoHV-1 virus production. The cell culture attached to microcarriers is an effi-cient method to enlarge the surface of cell growth and for large-scale cell production. Our studies reveal that MDBK adhered to MCs in 30 minutes and that initial agitation of culture did not influence on the efficiency of adhesion or cell growth. In our experiments, we detected no relevant influence of agitation on initial cell adhesion of MDBK to MCs. The maximum cell yield was similar to all initial conditions of agitation studied. The maximum yield obtained in culture started with 15, 20 and 30 cells / MC, was respectively.8.7 x105, 9.3 x105 and 9.8 x105 cells / ml . The cellular distribution on the MCs at the beginning of the culture was more heterogeneous in higher initial densities. After three medium exchanges during MDBK cell culture, the increase in the final yield was 100% higher than that from culture performed without medium change (0.93 x 106 cells / mL. Replacing 50% of the culture medium with fresh medium after 24 hours of growth, the concentration of glucose (5 mM and glutamine (1.8 mM were almost completely res-tored. In these studies, BoHV-1 infections of MDBK were performed after 48, 72 and 86 hours with daily exchanges of 50% of the medium. The increase in viral titer was proportional to the number of viable cells present at the time of infection. The best result of BoHV-1 production was achieved when the infection was performed from 86 hours of cell culture, reaching about 3.7 x108 (TCID50/ml after 24-48 hours of infection, being on average four times higher when compared to the

  18. The ecological movement in France

    International Nuclear Information System (INIS)

    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)

  19. 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

    2017-06-01

    The receptor for activated C kinase 1 (RACK1) belongs to a protein subfamily containing a tryptophan-aspartic acid-domain (WD) repeat structure. Compelling evidence indicates that RACK1 can interact with many signal molecules and affect different signal transduction pathways. In this study, a kale (Brassica oleracea var. acephala f.tricolor) RACK1 gene (BoRACK1) was cloned by RT-PCR. The amino acid sequence of BoRACK1 had seven WD repeats in which there were typical GH (glycine-histidine) and WD dipeptides. Comparison with AtRACK1 from Arabidopsis revealed 87.1% identity at the amino acid level. Expression pattern analysis by RT-PCR showed that BoRACK1 was expressed in all analyzed tissues of kale and that its transcription in leaves was down-regulated by salt, abscisic acid, and H 2 O 2 at a high concentration. Overexpression of BoRACK1 in kale led to a reduction in symptoms caused by Peronospora brassicae Gaumann on kale leaves. The expression levels of the pathogenesis-related protein genes, PR-1 and PRB-1, increased 2.5-4-fold in transgenic kale, and reactive oxygen species production was more active than in the wild-type. They also exhibited increased tolerance to salt stress in seed germination. H 2 O 2 may also be involved in the regulation of BoRACK1 during seed germination under salt stress. Quantitative real-time PCR analyses showed that the transcript levels of BoRbohs genes were significantly higher in overexpression of BoRACK1 transgenic lines. Yeast two-hybrid assays showed that BoRACK1 could interact with WNK8, eIF6, RAR1, and SGT1. This study and previous work lead us to believe that BoRACK1 may form a complex with regulators of plant salt and disease resistance to coordinate kale reactions to pathogens.

  5. 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.)

  6. Extraction and inhibition of enzymatic activity of botulinum neurotoxins/A1, /A2, and /A3 by a panel of monoclonal anti-BoNT/A antibodies.

    Suzanne R Kalb

    Full Text Available Botulinum neurotoxins (BoNTs are extremely potent toxins that are capable of causing death or respiratory failure leading to long-term intensive care. Treatment includes serotype-specific antitoxins, which must be administered early in the course of the intoxication. Rapidly determining human exposure to BoNT is an important public health goal. In previous work, our laboratory focused on developing Endopep-MS, a mass spectrometry-based endopeptidase method for detecting and differentiating BoNT/A-G serotypes in buffer and BoNT/A, /B, /E, and /F in clinical samples. We have previously reported the effectiveness of antibody-capture to purify and concentrate BoNTs from complex matrices, such as clinical samples. Because some antibodies inhibit or neutralize the activity of BoNT, the choice of antibody with which to extract the toxin is critical. In this work, we evaluated a panel of 16 anti-BoNT/A monoclonal antibodies (mAbs for their ability to inhibit the in vitro activity of BoNT/A1, /A2, and /A3 complex as well as the recombinant LC of A1. We also evaluated the same antibody panel for the ability to extract BoNT/A1, /A2, and /A3. Among the mAbs, there were significant differences in extraction efficiency, ability to extract BoNT/A subtypes, and inhibitory effect on BoNT catalytic activity. The mAbs binding the C-terminal portion of the BoNT/A heavy chain had optimal properties for use in the Endopep-MS assay.

  7. Jihadists’ Grievance Narratives against France

    Directory of Open Access Journals (Sweden)

    Laurence Bindner

    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

    2009-07-01

    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

  13. Batteries and accumulators in France

    International Nuclear Information System (INIS)

    2012-12-01

    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. This booklet presents the situation in France in 2011

    Gemstone commercial is a high revenue for Thailand especially ruby and sapphire. Moreover, Phrae is a potential gem field located in the northern part of Thailand. The studies of spectroscopic properties are mainly to identify gemstone using advanced techniques (e.g. UV-Vis-NIR spectrophotometry, FTIR spectrometry and Raman spectroscopy). Typically, UV-Vis-NIR spectrophotometry is a technique to study the cause of color in gemstones. FTIR spectrometry is a technique to study the functional groups in gem-materials. Raman pattern can be applied to identify the mineral inclusions in gemstones. In this study, the natural sapphires from Ban Bo Kaew were divided into two groups based on colors including blue and green. The samples were analyzed by UV-Vis-NIR spectrophotometer, FTIR spectrometer and Raman spectroscope for studying spectroscopic properties. According to UV-Vis-NIR spectra, the blue sapphires show higher Fe3+/Ti4+ and Fe2+/Fe3+ absorption peaks than those of green sapphires. Otherwise, green sapphires display higher Fe3+/Fe3+ absorption peaks than blue sapphires. The FTIR spectra of both blue and green sapphire samples show the absorption peaks of -OH,-CH and CO2. The mineral inclusions such as ferrocolumbite and rutile in sapphires from this area were observed by Raman spectroscope. The spectroscopic properties of sapphire samples from Ban Bo Kaew, Phrae Province, Thailand are applied to be the specific evidence for gemstone identification.

    Ganguly, P.; Rao, C.N.R.

    1980-01-01

    Systematics in the electrical and magnetic properties of transition metal perovskites LnBO 3 (Ln = rare-earth ion, B = 3d transition metal) with the variation of Ln and B ions are reviewed. The electrical resistivity and activation energy of LnBO 3 compounds increase with the decreasing size of the Ln 3+ ion for a given B ion. The low-spin to high-spin transition temperature of Co 3+ ion in LnCoO 3 similarly increase with the decrease in size of Ln 3+ while the magnetic ordering temperatures in LnVO 3 , LnFeO 3 , LnCrO 3 and LnSrCo 2 O 6 decrease with decreasing size of the rare-earth ion. These results may be understood in terms of the increasing acidity of the rare earth ion with decreasing size and the competition between the Ln 3+ and the B 3+ ions for covalency with the oxygen ions. The effect of this competition on the metal oxygen covalency and crystal field parameter is discussed in relation to the results obtained and Goodenough's phase diagram. The possibility of d-f exchange interaction in Lasub(1-x)Lnsub(x)NiOsub(3) is also discussed in the light of ESR results. (auth.)

    Single crystals of Sr2Mg(BO3)2 (SMBO) were grown by Kyropoulos method. X-ray powder diffraction (XRD) analysis, transmission spectrum, thermal properties, band structure, density of states and charge distribution as well as Raman spectra of SMBO were described. The as-grown SMBO crystals show wide transparency range with UV cut-off below 180 nm. A direct band gap of 4.66 eV was obtained from the calculated electronic structure results. The calculated band structure and density of states results indicated the top valence band is determined by O 2p states whereas the low conduction band mainly consists of Sr 5s states. Twelve Raman peaks were observed in the experimental spectrum, fewer than the number predicted by the site group analysis. Raman peaks of SMBO were assigned combining first-principle calculation and site group analysis results. The strongest peak at 917 cm-1 in the experimental spectrum is assigned to symmetric stretching mode A1‧(ν1) of free BO3 units. SMBO is a potential Raman crystal which can be used in deep UV laser frequency conversion.

    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 average, minimum and maximum weather indexes with the winter and summer regression equations for the different economical regions of France.

    Nested PCR and qPCR (quantitative PCR) tests based on glycoprotein B (gB) gene were designed for detecting Bovine herpesvirus 6 (BoHV6) in bovine whole blood samples and wild ruminant blood clots (deer and roe-deer). This virus, commonly known as BLHV (bovine lymphotropic herpesvirus) belongs to the Herpesviridae family, subfamily Gammaherpesvirinae and Macavirus genus. DNA isolated from 92 dairy cow blood samples and 69 wild ruminant clots were examined for the presence of BoHV6 using nested PCR and qPCR tests. Viral DNA was detected by using nested PCR in 59 out of 92 bovine blood samples (64.1%), and by qPCR in 68 out of 92 bovine blood samples (73.9%), but none out of 69 DNA samples isolated from wild ruminant blood clots, was positive in both assays. The specificity of nested PCR and qPCR was confirmed by using BoHV1, BoHV4, BoHV6, BFV, BIV, and BLV DNA. The sensitivity of nested PCR and qPCR was determined using a serially 10-fold diluted vector pCR2.1HgB (2 × 10(0)-2 × 10(6)copies/reaction). In this testing, qPCR was more sensitive than the nested PCR, detecting two copies of BoHV6 whilst the limit of detection for nested PCR was 20 copies. In all qPCR assays, the coefficients of determination (R(2)) ranged between 0.990 and 0.999, and the calculated amplification efficiencies (Eff%) within the range of 89.7-106.9. The intra- and inter-assay CV (coefficient of variation) values did not exceed 4%. Copyright © 2013 Elsevier B.V. All rights reserved.

    Due to its variegated and colorful leaves, ornamental kale (Brassica oleracea L. var. acephala) has become a popular ornamental plant. In this study, we report the fine mapping and analysis of a candidate purple leaf gene using a backcross population and an F 2 population derived from two parental lines: W1827 (with white leaves) and P1835 (with purple leaves). Genetic analysis indicated that the purple leaf trait is controlled by a single dominant gene, which we named BoPr. Using markers developed based on the reference genome '02-12', the BoPr gene was preliminarily mapped to a 280-kb interval of chromosome C09, with flanking markers M17 and BoID4714 at genetic distances of 4.3 cM and 1.5 cM, respectively. The recombination rate within this interval is almost 12 times higher than the usual level, which could be caused by assembly error for reference genome '02-12' at this interval. Primers were designed based on 'TO1000', another B. oleracea reference genome. Among the newly designed InDel markers, BRID485 and BRID490 were found to be the closest to BoPr, flanking the gene at genetic distances of 0.1 cM and 0.2 cM, respectively; the interval between the two markers is 44.8 kb (reference genome 'TO1000'). Seven annotated genes are located within the 44.8 kb genomic region, of which only Bo9g058630 shows high homology to AT5G42800 (dihydroflavonol reductase), which was identified as a candidate gene for BoPr. Blast analysis revealed that this 44.8 kb interval is located on an unanchored scaffold (Scaffold000035_P2) of '02-12', confirming the existence of assembly error at the interval between M17 and BoID4714 for reference genome '02-12'. This study identified a candidate gene for BoPr and lays a foundation for the cloning and functional analysis of this gene.

    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)

  11. [Health and politics in France].

    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

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.

    Bun'kov, Yu.M.; Punkkinen, M.; Yulinen, E.E.

    1978-01-01

    NMR of Fe 57 in FeBO 3 is investigated by pulsed magnetic resonance techniques in the 2 to 70 K temperature range. A dynamic NMR frequency shift is observed which is due to coupling between the NMR oscillations and the low-frequency AFMR mode, the magnitude of which only slightly exceeds the micro-inhomogeneous broadening of the NMR line caused by the spread of the value of hyperfine field at the nuclei. Under these conditions the nuclear spin system possesses a number of unusual properties. Thus, broadening of the magnetic resonance line is uniform, the magnitude of the homogeneous broadening depends on the angle of deviation of the nuclear magnetization from the equilibrium axis, and an echo signal is detected which is similar to the ''solid echo'' in substances with dipole broadening of the magnetic resonance line

    A field survey of terrestrial plants growing on Bo Ngam lead mine area, Thailand, was conducted to identify species accumulating exceptionally high concentrations of lead. Plant and soil samples were collected from five areas. Lead concentrations in surface soil ranged from 325 to 142 400 mg/kg. The highest lead concentration in soil was found at the ore dressing plant area and lowest at a natural pond area. In different areas, the concentrations of lead in plants were different when comparing various study sites. A total of 48 plant species belonging to 14 families were collected from five sampling sites. Twenty-six plant species had lead concentrations more than 1000 mg/kg in their shoots. Three species (Microstegium ciliatum, Polygala umbonata, Spermacoce mauritiana) showed extremely high lead concentrations in their shoots (12 200-28 370 mg/kg) and roots (14 580-128 830 mg/kg). - Uptake and accumulation of lead by plants

    1985-06-01

    The operation of the Fermilab BO low β insertion involves the coordinated control of the 4 strings of quadrupoles of the insertion itself along with several magnetic correction elements (20 dipoles for the closed orbit, 2 quad circuits for betatron tunes, 1 skew quad circuit for coupling, and 2 sextupole circuits for chromaticity). When the beam is stored at high energy, these elements must correct the errors induced by the strong superconducting quadrupoles of the insertion as the optics are smoothly changed from the fixed target configuration to the low β state. The techniques and control programs for these manipulations and initial tests using a single coasting beam are described. 6 refs., 4 figs

    Fe substitution effect on the magnetic behavior of Mn2-xFexBO4 (x = 0.3, 0.5, 0.7) warwickites has been investigated combining Mössbauer spectroscopy, dc magnetization, ac magnetic susceptibility, and heat capacity measurements. The Fe3+ ions distribution over two crystallographic nonequivalent sites is studied. The Fe introduction breaks a long-range antiferromagnetic order and leads to onset of spin-glass ground state. The antiferromagnetic short-range-order spin correlations persist up to temperatures well above TSG reflecting in increasing deviations from the Curie-Weiss law, the reduced effective magnetic moment and "missing" entropy. The results are interpreted in the terms of the progressive increase of the frustration effect and the formation of spin-correlated regions.

    A system of 0.03 mol Nd{sup 3+}-doped (Y,Gd)BO{sub 3} phosphors were prepared by the conventional solid state reaction method for different concentrations of Gd{sup 3+} ions and were characterized by X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM) and NIR emission measurements. The emitted radiation was dominated by 1057 nm peak in the NIR region as a result of {sup 4}F{sub 3/2} {yields} {sup 4}I{sub 11/2} transitions of Nd{sup 3+} ions. As the concentration of Gd{sup 3+} ions increases from 0.00 to 0.57 mol, the grain sizes and the intensity of NIR emission peaks were improved. The results are discussed in comparison with similar reported works.

    Nous présentons l'observation expérimentale de l'émission squentielle de photons par une boîte quantique unique sous pompage optique continu ou pulsé. Cette cascade radiative produit des paires de photons corrélés qui sont émis suivant un ordre bien défini. En effet, la fonction de corrélation croisée entre les deux photons formant la paire présente une allure asymétrique, de type groupement ou dégroupement de photons, suivant l'ordre temporel de détection des deux photons. Prédit théoriquement en physique atomique, ce comportement asymétrique de la fonction de corrélation de second ordre est la signature de l'émission successive de photons.

    We present a compact continuous wave (CW) external-cavity tunable Cr 3+ :LiCaAlF 6 (Cr:LiCAF) laser which is intracavity frequency doubled using a BiB 3 O 6 (BiBO) nonlinear crystal to obtain tunable blue–violet radiation. The generated second harmonic (SH) can be tuned by means of either angular or temperature variation of the nonlinear crystal. We have obtained SH radiation between 390–415 nm and a maximum output power of 34 mW at 400 nm. Future improvements on the SH tuning range and output power are addressed in the text. Our results may be applied in the design of compact tunable composite external-cavity solid-state lasers. (paper)

The main factors affecting particle size, particle distribution and luminescent properties of the product were investigated in detail, and as a result, the preparation processes were optimized. The phosphors were characterized by X-ray diffraction (XRD), scanning electronic microscope (SEM), transmission electronic microscope (TEM) and vacuum ultraviolet (VUV) spectra. Results reveal that phosphors with different morphology, small particle size and high luminescence intensity could be obtained by soft chemistry methods. The difference between the luminescence properties of phosphors in this work and commercial rare earth borate phosphor is discussed. The phosphor with grain shape and high luminescence intensity could be prepared by coprecipitation-combustion method, nanophosphor could be prepared by salt assisted combustion method, and spherical phosphor with a narrow size distribution could be obtained by using emulsion method

    Basic optical properties and radiation responses of undoped, Tm 3+ 1.0% and 2.0% activated Ca 3 (BO 3 ) 2 (CBO) crystalline scintillator prepared by the micro-pulling down (μ-PD) method are reported. Tm 3+ : CBO crystals showed three weak absorption bands around 190, 260 and 350 nm, owing to the Tm 3+ 4f–4f transition. Strong blue luminescence peaks at 360 and 460 nm which are ascribed to the 1 D 2 – 3 H 6 and 1 D 2 – 3 F 4 transitions of Tm 3+ respectively were observed under 241 Am 5.5 MeV α-ray excitation. The scintillation light yield of 2.0% Tm 3+ -doped CBO crystal was evaluated to be about 250 ph/n from the 252 Cf excited pulse height spectrum.

    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.

    Zinc borate, Zn(BO{sub 2}){sub 2}, doped with TbCl{sub 3} at different concentration (0.5-8 mol %) was synthesized. The polycrystalline samples were characterized by Scanning Electron Microscopy (Sem/EDS) and X-ray Diffraction. The X-ray difractrograms of the pure samples sintered at 750 and 800 degrees C shown the evidence of the Zn(BO{sub 2}){sub 2} has the body centered cubic (bcc) structure and a ZnB{sub 4}O{sub 7} primitive orthorhombic phase of the crystal system. The thermoluminescent (Tl) intensity was dependent on the thermal treatment (250-500 degrees C) and also on the impurity concentration. The glow curves show four glow peaks at about 82, 164, 251, and 331 degrees C when the Tb{sup 3+} doped zinc borate samples were exposed to gamma or beta radiation. The structure of the glow curves was analyzed by CGCD deconvolution method. The kinetics parameters (activation energy, frequency factor and the kinetic order) were calculated assuming the general order kinetics model describing accurately the Tl process. The glow peaks were overlapped and then the whole glow curve was considered for dosimetric characteristics measurements. The linear Tl response as a function of gamma and beta doses was performed using a {sup 60}Co irradiator and a {sup 90}Sr, respectively. Zinc borate with 8 mol % of impurity concentration exhibited an intense radio luminescent (Rl) emission. The Rl spectra show their maximum bands at 370, 490, 545 and 700 nm. The linear dose-response was between 2.2 c Gy and 27.7 Gy when the samples were exposed to beta radiation. These results suggest that the Tb -doped zinc borate material is a good phosphor for use in radiation dosimetry because its high Tl sensitivity to the ionizing radiation and good dose-response.

    Ninety-two strains of lactic acid bacteria (LAB) were isolated from a Malaysian food ingredient, chili bo, stored for up to 25 days at 28 degreesC with no benzoic acid (product A) or with 7,000 mg of benzoic acid kg-1 (product B). The strains were divided into eight groups by traditional phenotypic tests. A total of 43 strains were selected for comparison of their sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) whole-cell protein patterns with a SDS-PAGE database of LAB. Isolates from product A were identified as Lactobacillus plantarum, Lactobacillus fermentum, Lactobacillus farciminis, Pediococcus acidilactici, Enterococcus faecalis, and Weissella confusa. Five strains belonging to clusters which could not be allocated to existing species by SDS-PAGE were further identified by 16S rRNA sequence comparison. One strain was distantly related to the Lactobacillus casei/Pediococcus group. Two strains were related to Weissella at the genus or species level. Two other strains did not belong to any previously described 16S rRNA group of LAB and occupied an intermediate position between the L. casei/Pediococcus group and the Weissella group and species of Carnobacterium. The latter two strains belong to the cluster of LAB that predominated in product B. The incidence of new species and subspecies of LAB in chili bo indicate the high probability of isolation of new LAB from certain Southeast Asian foods. None of the isolates exhibited bacteriocin activity against L. plantarum ATCC 14917 and LMG 17682.

    We explore the influence of interstitial iron (Fei) on lifetime spectroscopy of boron-oxygen (B-O) related degradation in p-type Czochralski silicon. Theoretical and experimental evidence presented in this study indicate that iron-boron pair (Fe-B) related reactions could have influenced several key experimental results used to derive theories on the fundamental properties of the B-O defect. Firstly, the presence of Fei can account for higher apparent capture cross-section ratios (k) of approximately 100 observed in previous studies during early stages of B-O related degradation. Secondly, the association of Fe-B pairs can explain the initial stage of a two-stage recovery of carrier lifetime with dark annealing after partial degradation. Thirdly, Fei can result in high apparent k values after the permanent deactivation of B-O defects. Subsequently, we show that a single k value can describe the recombination properties associated with B-O defects throughout degradation, that the recovery during dark annealing occurs with a single-stage, and both the fast- and slow-stage B-O related degradation can be permanently deactivated during illuminated annealing. Accounting for the recombination activity of Fei provides further evidence that the B-O defect is a single defect, rather than two separate defects normally attributed to fast-forming recombination centers and slow-forming recombination centers. Implications of this finding for the nature of the B-O defect are also discussed.

    Clostridium botulinum is an obligate anaerobic, Gram positive bacterium that secretes extremely toxic substances known as botulinum neurotoxins (BoNTs) that cause serious paralytic illness called botulism. Based upon the serological properties, these neurotoxin have been classified into seven serotypes designated from A to G. Due to extreme toxicity of BoNTs, these neurotoxins have been designated as category A biowarfare agents. There is no commercial neutralizing antibody available for the treatment of botulism. Hence there is an urgent need to develop therapeutic intervention for prevention and cure of botulism within short period. BoNT antiserum injection is still the effective treatment. In the present study, the recombinant light chain of BoNT/E was successfully purified in soluble form. The purified rBoNT/E LC was used for the generation of polyclonal antibody in rabbit. In order to find out the neutralizing capacity of generated antisera, rabbit antiserum was incubated with 20 LD50 of botulinum neurotoxin type E for 1 hour at 37°C and then injected intraperitoneally (IP) into mice. Further in another set of experiments antiserum was administered in different ways that included administration of - antiserum and BoNT/E toxin simultaneously without preincubation, one after another at the same and different time points for its therapeutic ability. To find out cross neutralization capacity, rBoNT/E LC antiserum was pre-incubated with 5 LD50 of BoNT/A, BoNT/B, BoNT/F and then injected (IP) into mice. In all the cases mice were observed continuously for 96 hours. The results clearly indicate that developed polyclonal rabbit antiserum showed serotype specific neutralization of BoNT/E toxin only but not of BoNT/A, BoNT/B and BoNT/F. The developed antibodies will be used for preventive and therapeutic intervention of type 'E' botulism.

    Full Text Available A series of doped KCa4(BO33:Ln3+ (Ln: Dy, Eu and Tb compositions were synthesized by solid–state reaction method and their photoluminescent properties were systematically investigated to ascertain their suitability for application in white light emitting diodes. The X–ray diffraction (XRD and nuclear magnetic resonance (MAS–NMR data indicates that Ln3+–ions are successfully occupied the non–centrosymmetric Ca2+ sites, in the orthorhombic crystalline phase of KCa4(BO33 having space group Ama2, without affecting the boron chemical environment. The present phosphor systems could be efficiently excitable at the broad UV wavelength region, from 250 to 350 nm, compatible to the most commonly available UV light–emitting diode (LED chips. Photoluminescence studies revealed optimal near white–light emission for KCa4(BO33 with 5 wt.% Dy3+ doping, while warm white–light (CIE; X = 0.353, Y = 0.369 is obtained at 1wt.% Dy3+ ion concentration. The principle of energy transfer between Eu3+ and Tb3+ also demonstrates the potential white–light from KCa4(BO33:Eu3+,Tb3+ phosphor. Whereas, single Tb3+ and Eu3+–doped systems showed bright green (Tb3+ and red (Eu3+ emissions, respectively. Having structural flexibility along with remarkable chemical/thermal stability and suitable quantum efficiency these phosphors can be promising candidates as white–light–emitter for near UV LEDs.

  20. Theory of the orthogonal dimer Heisenberg spin model for SrCu sub 2 (BO sub 3) sub 2

    Miyahara, S

    2003-01-01

    The magnetic properties of SrCu sub 2 (BO sub 3) sub 2 are reviewed from a theoretical point of view. SrCu sub 2 (BO sub 3) sub 2 is a new two-dimensional spin gap system and its magnetic properties are well described by a spin-1/2 antiferromagnetic Heisenberg model of the orthogonal dimer lattice. The model has a dimer singlet ground state whose exactness was proven by Shastry and Sutherland for a topologically equivalent model more than 20 years ago. The exactness of the ground state is maintained even if interlayer couplings are introduced for SrCu sub 2 (BO sub 3) sub 2. In the two-dimensional model, quantum phase transitions take place between different ground states for which three phases are expected: a gapped dimer singlet state, a plaquette resonating valence bond state and a gapless magnetic ordered state. Analysis of the experimental data shows that the dimer singlet ground state is realized in SrCu sub 2 (BO sub 3) sub 2. The orthogonality of the dimer bonds, which is the underlying symmetry of th...

    Full Text Available Abstract Background Bovine herpesvirus 5 (BoHV-5 is a member of the subfamily Alphaherpesvirinae responsible for meningo-encephalitis in young cattle. The first case of bovine meningo-encephalitis associated with a herpesvirus infection was reported in Australia. The current geographical distribution of BoHV-5 infection is mainly restricted to South America, especially Brazil and Argentina. Outbreaks of BoHV-5 are regularly observed in Argentina suggesting the circulation of the virus in the bovine population. Results Seventeen field strains of BoHV-5 isolated from 1984 to now were confirmed by differential PCR and subjected to restriction endonuclease analysis (REA. Viral DNA was cleaved with BstEII which allows the differentiation among subtypes a, b and non a, non b. According to the REA with BstEII, only one field strain showed a pattern similar to the Argentinean A663 strain (prototype of BoHV-5b. All other isolates showed a clear pattern similar to the Australian N569 strain (prototype of BoHV-5a consistent with the subtypes observed in Brazil, the other South-American country where BoHV-5 is known to be prevalent. The genomic region of subtype b responsible for the distinct pattern was determined and amplified by PCR; specifically a point mutation was identified in glycoprotein B gene, on the BstEII restriction site, which generates the profile specific of BoHV-5b. Conclusions This is the first report of circulation of BoHV-5a in Argentina as the prevailing subtype. Therefore the circulation of BoHV-5b was restricted to a few years in Argentina, speculating that this subtype was not able to be maintained in the bovine population. The mutation in the gB gene is associated with the difference in the restriction patterns between subtypes "a" and "b".

    Full Text Available Bovine herpesvirus type 1 (BoHV-1, is responsible for clinical manifestations such as infectious bovine rhinotracheitis, abortion, conjunctivitis, infectious pustular vulvovaginitis and balanoposthitis. This virus has been responsible for major losses in different productive and reproductive herds in the country. Thus, the objective of this study was to estimate the frequency of antibodies against BoHV-1 in beef heifers not vaccinated in Microregion of Imperatriz, Maranhao, and identify the age group most affected by the virus, as well as a study of factors associated with virus infection and to evaluate the indirect ELISA using the serum neutralization (SN as a reference standard. The study was conducted in 48 herds, cutting, distributed in 12 counties of Microregion of Imperatriz. The samples were collected from female cattle stratified into three age groups, ? 12 months, between 12 and 36 months and ? 36 months of age. The samples were subjected to two serological tests, ELISA and SN. In each herd, an epidemiological questionnaire was applied in order to obtain information on management and reproductive sanitary, for the study of risk factors. The frequency of antibodies against BoHV-1 in Microregion of Imperatriz was 63.23%, and the municipalities of Açailândia Buritirana showed the highest frequencies, both with 80.44%, the most affected age group, the Microregion, was animals aged ? 36 months (69.65%. Based on the results we can conclude that the frequency of antibodies against BoHV-1 is high, between the age groups most affected were the animals aged ? 36 months were considered risk factors for virus transmission, return to estrus (OR=1.874, recovery of animals from other states / region (OR=1.365 and the creation of goat / sheep associated with bovine (OR=1.348, the indirect ELISA technique showed moderate concordance when compared to SN technique, which is the gold standard technique for diagnosis of BoHV-1.

  5. A safe energy supplying for France

    2001-01-01

    Contrarily to other European nations like United-kingdom, Germany or Norway, France has no important fossil energy resources. 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.)

    Taking into account the french and german relations concerning the nuclear activities, the nuclear phaseout decided by the german government in 1998 presents inevitable impacts in France. The author discusses the constraints bound to this project (industrial interests, energy dependence...), the short dated phaseout project and the consequences for the relations of the two countries, Germany and France.

    There is very little knowledge in the Netherlands of how economic private law and public law are enforced in France. In France too, however, scant information can be gleaned. There is little if any contact in the university community between criminal law and administrative law, partly because

  11. Which energy transition for France?

    International Nuclear Information System (INIS)

    Criqui, Patrick

    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

  12. 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.

    2011-01-01

    This report first gives an overview of the economic and energetic context for 2010: revival of activity and trade at the world level but moderate in the euro zone and in France, an exceptionally cold year, a new increase of energy prices. It briefly comments the moderate demand resumption. It comments the evolutions of productions, trade and consumptions of different energies (coal, oil, natural gas, electricity, and renewable energies). It comments the resumption of energy final consumption in the main sectors (industry, housing and office buildings, agriculture and fishery, transports). It outlines a slight improvement of energy efficiency, the slight decrease of greenhouse gas emissions related to energy consumption, and a 20% increase of the French energy bill

  14. 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.)

  15. Radioactive waste management in France

    Faussat, A.

    1988-01-01

    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

    Pale-yellow single crystals of the new borate tellurate(VI) Bi{sub 3}TeBO{sub 9} were obtained by reaction of stoichiometric amounts of Bi{sub 2}O{sub 3}, B{sub 2}O{sub 3}, and Te(OH){sub 6} at 780 C. The non-centrosymmetric crystal structure (P6{sub 3}, Z=2, a=8.7454(16), c=5.8911(11) Aa, 738 refl., 43 param, R1=0.037, wR2=0.093) contains isolated trigonal-planar BO{sub 3} units and nearly undistorted TeO{sub 6} octahedra. The Bi{sup 3+} cations are located in between in octahedral voids. The BiO{sub 6} octahedra are significantly distorted to a [3+3] pattern (2.25/2.50 Aa) due to the ns{sup 2} configuration. According to the structural features, the formula can be written as Bi{sub 3}(TeO{sub 6})(BO{sub 3}). Alternatively, the structure can also be described as hcp of oxygen with Te{sup VI} and Bi{sup III} in octahedral voids and B{sup III} in trigonal- planar voids. The vibrational spectra show the typical features of BO{sub 3} and TeO{sub 6} units with a significant {sup 10}B/{sup 11}B isotopic splitting of the IR-active B-O valence mode (1248 and 1282 cm{sup -1}). The UV/Vis spectrum shows an optical band edge with an onset around 480 nm (2.6 eV). MAS-NMR spectra of {sup 11}B show an anisotropic signal with a quadrupole coupling constant of C{sub Q}=2.55 MHz. and a very small deviation from rotational symmetry (η=0.2). The isotropic chemical shift is 20.1 ppm. The second harmonic generation (SHG) test was positive with an activity comparable to potassium dihydrogen phosphate (KDP). Bi{sub 3}TeBO{sub 9} decomposes in air at 825 C to Bi{sub 2}TeO{sub 5}. (copyright 2017 Wiley-VCH Verlag GmbH and Co. KGaA, Weinheim)

    Botulinum neurotoxins (BoNTs) are among the most potent toxic bacterial proteins for humans, which make them potential agents for bioterrorism. Therefore, an ultrasensitive detection of BoNTs and their active states is in great need as field-deployable systems for anti-terrorism applications. We report the construction of a novel graphene oxide (GO)-peptide based fluorescence resonance energy transfer (FRET) biosensor for ultrasensitive detection of the BoNT serotype A light chain (BoNT-LcA) protease activity. A green fluorescence protein (GFP) modified SNAP-25 peptide substrate (SNAP-25-GFP) was optimally designed and synthesized with the centralized recognition/cleavage sites. This FRET platform was constructed by covalent immobilization of peptide substrate on GO with BSA passivation which have advantages of low non-specific adsorption and high stability in protein abundant solution. BoNT-LcA can specifically cleave SNAP-25-GFP substrate covalently immobilized on GO to release the fragment with GFP. Based on fluorescence signal recovery measurement, the target BoNT-LcA was detected sensitively and selectively with the linear detection range from 1fg/mL to 1pg/mL. The limit of detection (LOD) for BoNT-LcA is around 1fg/mL. Copyright © 2014 Elsevier B.V. All rights reserved.

    2010-05-01

    A French long term monitoring network of permafrost and frost related processes, named PermaFRANCE, is being built since two years. It will represent the French contribution to the Alpine wide PermaNET network. The PermaFRANCE network will focus not only on permafrost, but on all frost related phenomena at different altitudinal levels, including both thermal monitoring and process observation and monitoring : 1) continuous and discontinuous permafrost in rock walls : - thermal monitoring is mainly performed at the Aiguille du Midi (Mont Blanc massif) and includes rock surface temperature (RST) and temperature profils in medium depth boreholes (10 m) ; - inventory and observation of rockfall activity in high mountain rock walls : this action concerns the whole Mont Blanc area and is based on a hitorical inventory and an observation of current activity based on a network of observers and contributors ; 2) discontinuous permafrost is surficial deposits and flat bedrock : - thermal monitoring is performed on five rockglacier sites and includes ground surface temperature (GST) and annual BTS campaigns on some sites. Two medium depth boreholes (15 m) have been made in 2009 on one site, and equipped for thermal profile monitoring. A deep borehole (100 m) will be made in 2010 at 45° N latitude ; - geophysical monitoring is performed on 4 sites : repeated vertical electrical soundings exist for some sites since 20 years, and have been complemented since 2007 by eletrical resistivity tomography (ERT) and refraction seismics ; - surficial displacements of rockglaciers : surficial displacements are measured either by classical geodesy or by DGPS on 6 rockglaciers ; 3) sporadic permafrost at middle altitudes : - an inventory of cold scree slopes and biological investigations on soil and tree growth (dendrogeomorphology) have already been achieved ; - a thermal monitoring should be initiated on selected sites in 2010 ; 4) seasonal frost and frost/thaw cycles at middle and low

    Graphical abstract: - Highlights: • Pancake-like/flower-like/leaf-like GdBO{sub 3} were obtained via a hydrothermal method. • Gd(OH){sub 3} nanorods and borates were used as the precursors for the first time. • A dissolution and recrystallization process was happened induced by the excess borax. • Three products have the similar stacked arrangements to reduce the surface energy. • The luminescence properties of GdBO{sub 3}:Eu{sup 3+} are related to shape and crystallinity. - Abstract: Monodisperse pancake-like/flower-like/leaf-like GdBO{sub 3} samples have been successfully synthesized via a designed hydrothermal conversion method using H{sub 3}BO{sub 3}, Na{sub 2}B{sub 4}O{sub 7}·10H{sub 2}O, or NaBO{sub 2}·4H{sub 2}O as boron sources, respectively. It was found that different boron sources have crucial influences on the formation and morphology of the products. The Gd(OH){sub 3} nanorods precursors were prepared through a simple hydrothermal process, which then served as sacrificial templates for the fabrication of GdBO{sub 3} micropancakes/microflowers/microleaves via a hydrothermal conversion process. FT-IR spectra confirm that vaterite-type GdBO{sub 3} can be synthesized by this method. The possible formation mechanisms for different microstructures were put forward on the basis of a series of time-dependent control experiments. The products have similar stacked arrangements driven by the minimization of the interfacial and surface energy of the hydrothermal system. An investigation on the photoluminescence (PL) properties of GdBO{sub 3}:Eu{sup 3+} samples with different morphologies indicates that the PL properties of as-obtained GdBO{sub 3}:Eu{sup 3+} phosphors are strongly dependent on their morphology and crystallinity. The flower-like structure exhibits the strongest red emission.

    New data on the ground state of impurity Ru{sup 3+} ions in the crystals of YAl{sub 3}(BO{sub 3}){sub 4} and EuAl{sub 3}(BO{sub 3}){sub 4} aluminum borates were obtained. It was shown that Ru{sup 3+} ion replaces trivalent rare-earth ions without breaking the symmetry of the site. The crystal field acting on 4d{sup 5} ions forms an EPR spectrum, which is described by the spin Hamiltonian with S=1/2. The spin-Hamiltonian parameters determined are equal to g{sub II}=1.963, g{sub ⊥}=3.796, A{sub II}=43.03*10{sup −4} cm{sup −1}, A{sub ⊥}=84.86*10{sup −4} cm{sup −1} in the YAl{sub 3}(BO{sub 3}){sub 4} crystal (at T=15 K) and g{sub II}=2.016, g{sub ⊥}=3.796 in the EuAl{sub 3}(BO{sub 3}){sub 4} crystal (at T=15 K). It is found that the value of ∆g=g{sub II}-g{sub ⊥} is an indicator of distortions of nearest environment of Ru{sup 3+} ion. The angle between the C{sub 3} axis and the direction into nearest oxygen ion was determined. The EPR linewidth of Ru{sup 3+} ion increases with increasing temperature due to the dipole-dipole and exchange interactions with the excited states of the host lattice Ru{sup 3+} ion.

    Full Text Available Phototrophic microorganisms (cyanobacteria and algae and microfungi, were identified from biofilm on the walls of the entrance of BožanaCavein west Serbia. Temperature, relative humidity and light intensity were measured, and chlorophyll a content determined. Light intensity differed from the entrance inwards. However, Chl a content was not proportional to light intensity, instead it was positively correlated to biofilm weight. Biofilm samples from two sites were also observed using a scanning electron microscope. Coccoid forms of cyanobacteria were abundant at the sampling site with the lowest light intensity, while members of the order Nostocales were predominant at the sampling site with the highest light intensity measured. Cyanobacteria were the dominant group of phototrophs colonizing cave walls (29 taxa, with the order Chroococcales prevailing (21 taxa. The most frequently documented cyanobacteria were species from genera Gloeocapsa, Scytonema, Aphanocapsa and Chroococcus. Desmococcus olivaceus and Trentepohlia aurea were the only green algae documented on cave walls. Ascomycetes were common (e.g. Alternaria, Aspergillus, Cladosporium, Epicoccum, Penicillum and Trichoderma, while zygomycetes and oomycetes were less frequent. The different color of each biofilm sample was ascribed to the presence of various different species of cyanobacteria and algae.

    International Nuclear Information System (INIS)

    Wells, Jon-Paul R; Yamaga, Mitsuo; Han, Thomas P J; Honda, Makoto

    2003-01-01

    We report on the electron paramagnetic resonance (EPR) and optical absorption and fluorescence spectroscopy of YAl 3 (BO 3 ) 4 single crystals doped with 0.2 mol% of trivalent chromium. From EPR we determine that the Cr 3+ ions reside in sites of essentially octahedral symmetry with an orthorhombic distortion. The ground state 4 A 2 splitting is determined to be 2√D 2 + 3E 2 ∼ 1.05 ± 0.04 cm -1 , where D and E are fine-structure parameters, and we can attribute this splitting to the combined effect of a low-symmetry distortion and spin-orbit coupling. The g-values and fine-structure parameters D and E of the ground state 4 A 2 are measured to be g x ∼ g y ∼ g z = 1.978 ± 0.005, vertical bar D vertical bar = 0.52 ± 0.02 cm -1 and vertical bar E vertical bar 0.010 ± 0.005 cm -1 respectively. From 10 K optical absorption we have measured the position and crystal-field splittings of the 2 E, 2 T 1 , 4 T 2 , 2 T 2 and 4 T 1 states with the 4 T 2 and 4 T 1 levels appearing as vibronically broadened bands

    2013-01-01

    Full Text Available The Bo-Kaap is an older inner-city, working-class neighbourhood in Cape Town, South Africa. By the 1930s, the area had degenerated into an overcrowded and run-down neighbourhood, consisting largely of dilapidated houses, but by 1941 about 150 housing units had been expropriated by the local authority for redevelopment in a comprehensive renewal scheme for the area. However, the process was halted with the formation of the so-called “Group for the Preservation of the Malay Quarter”, which fought against the demolition of the houses. At present, the area with its colourful housing units and 11 mosques is part of Cape Town’s cultural heritage and a very important tourist attraction. As in the case of De Waterkant, a gentrified neighbourhood adjacent to it, the area has seen a large number of housing units renovated and upgraded. Property prices have increased dramatically, although they are still relatively low, while the number of properties sold is also on the rise – so much so that the community leaders and especially the Muslim residents are in a constant battle to preserve the neighbourhood’s cultural identity.

    Lanthanum calcium oxoborate (LaCOB) is a nonlinear optical (NLO) material that belongs to the calcium-rare-earth (R) oxoborate family, with general composition Ca 4 RO(BO 3 ) 3 (R 3+ =La, Sm, Gd, Lu, Y). X-ray photoemission, photoabsorption, and resonant fluorescence were applied to study the electronic structure of this material. High resolution photoemission measurements on the valence band (VB) electronic structure and La 3d and 4d, Ca 2p, B 1s, and O 1s core lines were used to evaluate the surface and near surface chemistry. Element specific density of unoccupied electronic states in LaCOB were probed by X-ray absorption spectroscopy (XAS) at the La 3d (M 4,5 -edge), B 1s, and O 1s (K-edges) absorption edges. Soft X-ray fluorescence was used to further examine valence band states associated with spectral differences noted in the absorption measurements. These results provide the first measurements of the electronic structure and surface chemistry of this rare-earth oxoborate

    Duco, J.; Reocreux, M.; Tattegrain, A.

    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

    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

  13. 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

    2007-12-01

    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

    2001-01-01

    This small guidebook summarizes the main statistical data on energy for France. Data are presented in tables and graphs for the last decades up to the year 2000: energy in economy (contribution of energy industries to the national gross product, employment and investments in the energy sector), overall energies (average monthly price of crude oil, public opinion about nuclear energy, supplies and consumptions, primary energy production, consumption per energy and per sector, energy bill, import crude oil prices), petroleum (primary production, sectoral end-consumption of refined petroleum products, consumption per type of product, automotive fuels demand, imports and exports of petroleum products, petroleum bill), natural gas (total production, sectoral consumption, imports per country of production, imports bill), coal (production, sectoral consumption, imports per country of production), electricity (gross production, classical thermal production per type of fuel, simplified status, sectoral final consumption, nuclear sites, electricity trades with foreign countries), renewable energies (total production, district heating networks, wood consumption, installed wind power, solar thermal and photovoltaic production), rational use of energy (primary energy intensity, compared evolutions of the national gross product with the energy consumption, cumulated energy savings), prices (energies in the industry and in the domestic sectors, automotive fuels, energy consumptions in households), environment (sectoral and net CO 2 emissions). An energy units conversion table is added at the end of the booklet. (J.S.)

    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

    Magnetic properties of heterometallic warwickites MgFeBO{sub 4,} Mg{sub 0.5}Co{sub 0.5}FeBO{sub 4,} and CoFeBO{sub 4} are presented, highlighting the effect of Co substitution on the magnetic properties of these compounds. The analysis of magnetization and heat capacity data has shown that these compounds exhibit a spin-glass transition below T{sub SG}=10, 20 and 22 K, respectively. Using zero field ac susceptibility as entanglement witness we find that the low dimensional magnetic behavior above T{sub SG} show quantum entanglement behavior χ(Τ)∝T{sup −α(Τ)} up to T{sub E}≈130 K. The α parameters have been deduced as a function of temperature and Co content, indicating the existence of random singlet phase in this temperature region. Above T{sub E} the paramagnetism is interpreted in terms of non-entangled spins giving rise to Curie–Weiss paramagnetism. The different intra- and inter-ribbon exchange interaction pathways have been calculated within a simple indirect coupling model. It is determined that the triangular motifs in the warwickite structure, together with the competing interactions, induce frustration. The spin-glass character is explained in terms of the substitutional disorder of the Mg, Fe and Co atoms at the two available crystallographic sites, and the frustration induced by the competing interactions. The Co substitution induces uniaxial anisotropy, increases the absolute magnetization and increases the spin-glass freezing temperature. The entanglement behavior is supported in the intermediate phase irrespective of the introduction of anisotropy by the Co substitution. - Highlights: • Spin-glass transition of MgFeBO{sub 4,} Mg{sub 0.5}Co{sub 0.5}FeBO{sub 4,} and CoFeBO{sub 4}. • Anisotropy and transition temperature T{sub SG} increases with Co substitution. • Dynamical scaling theory near T{sub SG} is fulfilled. • Quantum entanglement is observed in between T{sub SG} and T{sub E}=130 K. • Low dimensional random singlet phase

    Polarized spectroscopic properties related to 1.07 μm laser operation of a 1.8 at.% Nd3+:LaBO2MoO4 crystal grown by the Czochralski method were investigated at room temperature. Using a 2.2-mm-thick, Z-cut Nd3+:LaBO2MoO4 crystal as gain medium, orthogonally polarized dual-wavelength laser at 1,068 and 1,074 nm was first realized in a plano-concave resonator end-pumped by a quasi-continuous-wave 795 nm diode laser. A total output peak power of 1.2 W with slope efficiency of 26 % around 1.07 μm was obtained. The influences of resonator length and pump power on output laser wavelength were also investigated.

    LiSr 4 (BO 3 ) 3 :0.01Ce 3+ phosphor was investigated to assess its potential as a material for measurements of radiotherapeutic doses with electron spin resonance (ESR). The ESR spectrum of the phosphor irradiated with 60 Co features five ESR signals. An isochronal annealing experiment has shown that the strongest of these signals is associated with the same trap center as the 473 K peak on the TL glow curve of this material. The dose–response is linear in the studied range from 0.89 to 90.30 Gy. Fading of the signal was also investigated. - Highlights: • LiSr 4 (BO 3 ) 3 :Ce 3+ phosphor can be used as an ESR dosimeter for radiation therapy. • The ESR signal originates from the same traps as the TL. • Dose–response is linear, and the fading is slow

    Four cases were selected for comparison with theoretical predictions using stability data obtained during the flight test of the Bearingless Main Rotor (BMR) on a Messerschmidt-Boelkow-Blohm BO 105 helicopter. The four cases selected form the flight test included two ground resonance cases and two air resonance cases. The BMR used four modified BO 105 blades attached to a bearingless hub. The hub consisted of dual fiberglass C-channel beams attached to the hub center at 0.0238R and attached to the blade root at 0.25R with blade pitch control provided by a torque tube. Analyses from Bell Helicopter Textron, Boeing Vertol, and Sikorsky Aircraft were compared with the data and the correlation ranged from very poor-to-poor to poor-to-fair.

  3. 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

    UV-induced acoustooptics was explored for BaHf(BO{sub 3}){sub 2} microcrystallites with sizes varying within 5–30 μm range. The titled microcrystallites were embedded into the polymer matrices. The results were analyzed using both experimental optical as well as theoretical DFT approach. The measurements were done for principal acoustical frequencies: 0.5 MHz, 1 MHz, 2 MHz, and 3 MHz. The acoustical waves were excited by an electromechanical LiNbO{sub 3} piezoceramics transducers from acoustical generator. We explored dependence of the acoustooptical efficiency versus the photoinducing laser beam power, angle between the beams, acoustical power light polarization and temperature. We explored variation of the acoustooptical efficiency at 1150 nm probing cw He-Ne laser wavelength under influence of pulsed nitrogen laser at wavelength 371 nm working in the 7 ns regime with frequency repetition 6 Hz at power densities up to 900 MW/cm{sup 2}. Existence of some optimal conditions at about 1 MHz and UV photoinduced power equal to about 0.8 MW/cm{sup 2} was found. The spatial acousooptical gratings formation was observed. The DFT simulations of the charge density in main structural fragments under photoinducing UV beams is presented and principal role of the BO{sub 3} structural fragments is established. This is confirmed by crystallochemistry analysis. The phenomenological description is also presented. - Graphical abstract: Principal relation between the crystallochemistry and acoustically induced charge density space distribution changes. UV induced acoustooptical behaviours. - Highlights: • UV-induced increase of acoustooptics of BaHf(BO{sub 3}){sub 2} microcrystallites shown. • Principal role of the crystalline nano-interfaces is shown. • BO{sub 3} fragments play principal role.

    De-identification allows faster and more collaborative clinical research while protecting patient confidentiality. Clinical narrative de-identification is a tedious process that can be alleviated by automated natural language processing methods. The goal of this research is the development of an automated text de-identification system for Veterans Health Administration (VHA) clinical documents. We devised a novel stepwise hybrid approach designed to improve the current strategies used for text de-identification. The proposed system is based on a previous study on the best de-identification methods for VHA documents. This best-of-breed automated clinical text de-identification system (aka BoB) tackles the problem as two separate tasks: (1) maximize patient confidentiality by redacting as much protected health information (PHI) as possible; and (2) leave de-identified documents in a usable state preserving as much clinical information as possible. We evaluated BoB with a manually annotated corpus of a variety of VHA clinical notes, as well as with the 2006 i2b2 de-identification challenge corpus. We present evaluations at the instance- and token-level, with detailed results for BoB's main components. Moreover, an existing text de-identification system was also included in our evaluation. BoB's design efficiently takes advantage of the methods implemented in its pipeline, resulting in high sensitivity values (especially for sensitive PHI categories) and a limited number of false positives. Our system successfully addressed VHA clinical document de-identification, and its hybrid stepwise design demonstrates robustness and efficiency, prioritizing patient confidentiality while leaving most clinical information intact.

  6. A contribution to better understanding of structural characteristics and tectonic phases of the Boč region, Periadriatic Fault Zone

    Full Text Available The aim of this study was to determine properties of the tectonic contact between Permian/Mesozoic limestones and less competent Miocene clastites on the northeastern foothill of the Boč Mt. Because fault planes signifiantly mark the relief, this contact was studied by a detailed structural mapping, which showed that the Boč Mt. is limited by subvertical faults in its northeastern part. To ensure that mapped subvertical contact is compatible with regional geodynamics of the area, additionally paleostress analysis of fault-slip data was performed. Four individual paleostress tensor groups were documented in a wider Boč area and compared by published structural data from the border zone between Alps, Dinarides and Pannonian Basin. The oldest paleostress tensor group (Phase 1 is likely of Lower and Middle Miocene age and indicates SW-NE extension accommodated by W-E to WNW-ESE striking normal faults. Phase 2 can be correlated with Middle to Late Miocene NW-SE to WNWESE directed extension accommodated by NNE-SSW striking normal faults. Phase 3 is correlated with Late Miocene W-E directed contraction accommodated by N-S striking sinistral faults and NNE-SSW to NE-SW striking dextral faults. The youngest paleostress tensor group (Phase 4 fis well with Pliocene to Quaternary NNW-SSE to N-S directed contraction accommodated by NW-SE to W-E striking dextral faults and NE-SW striking reverse faults. Since the documented paleostress phases fis well with the geodynamic processes of the Alps-Dinarides-Carpathians territory the subvertical border in the northeastern part of Boč Mt. seems to be an acceptable structural solution. The study is important because the study area is located at interaction zone between two major Alpine fault systems: the Periadriatic and the Lavanttal faults.

    2010-01-01

    The magnetic properties of SrCu 2 (BO 3 ) 2 , a model spin system on the two-dimensional (2D) Shastry-Sutherland lattice, are reviewed with particular emphasis on the nuclear magnetic resonance (NMR) experiments. SrCu 2 (BO 3 ) 2 has a dimer singlet ground state at zero magnetic field and shows a sequence of magnetization plateaux at high magnetic fields. The plateaux are attributed to the localization of triplets into a superlattice due to mutual repulsion. Such a superstructure has been indeed observed at the 1/8 plateau by NMR experiments. Furthermore, the superstructure persists above the 1/8 plateau, where new phases have been identified by the torque and NMR measurements. SrCu 2 (BO 3 ) 2 also has the anisotropic Dzyaloshinski-Moriya interactions, which significantly change the ground state in magnetic fields. A recent development is the discovery of a new magnetic phase transition under high pressure. At 2.4 GPa, the 11 B NMR spectrum exhibits line splitting as a function of temperature in two steps. A gradual splitting below 30 K indicating loss of four-fold symmetry is followed by a further sudden splitting below 4 K marking a clear magnetic phase transition. The low-T phase has a doubled unit cell, yet with no spontaneous magnetic moment. A new type of valence-bond-solid (VBS) order is proposed. (author)

  12. Data Mining of Acupoint Characteristics from the Classical Medical Text: DongUiBoGam of Korean Medicine

    2014-01-01

    Full Text Available Throughout the history of East Asian medicine, different kinds of acupuncture treatment experiences have been accumulated in classical medical texts. Reexamining knowledge from classical medical texts is expected to provide meaningful information that could be utilized in current medical practices. In this study, we used data mining methods to analyze the association between acupoints and patterns of disorder with the classical medical book DongUiBoGam of Korean medicine. Using the term frequency-inverse document frequency (tf-idf method, we quantified the significance of acupoints to its targeting patterns and, conversely, the significance of patterns to acupoints. Through these processes, we extracted characteristics of each acupoint based on its treating patterns. We also drew practical information for selecting acupoints on certain patterns according to their association. Data analysis on DongUiBoGam’s acupuncture treatment gave us an insight into the main idea of DongUiBoGam. We strongly believe that our approach can provide a novel understanding of unknown characteristics of acupoint and pattern identification from the classical medical text using data mining methods.

    Full Text Available This paper attempts to investigate the lack of knowledge attitude and practices of street food vendors in Bo the Southern Province of Sierra Leone. A cross sectional study conducted among eighty-seven respondents vendors in forty-four in Bo City. Data was collected using a structured and semi structured questionnaire. The collected data is analysed using a simple descriptive statistics with the help Excel Microsoft ware. A statistical significance was found in relation to knowledge. Attitude towards food safety was negative self-reported practices by Street Food Vendors were statistically significant with low hygiene standards while predisposing factors showed relatively low personal hygiene poor environmental sanitation and low food safety practice. The realize consequences are utmost health risks of consuming street foods as food contamination has caused food borne diseases and outbreaks. It is recommended that standard training be provided for these vendors by the Bo City Council in collaboration with Njala University. It is essential that poor people in a developing country such as Sierra Leone be allowed to earn their livelihood by means of an easy-to-enter business such as street food vending when hygiene standards are sustained.

    Highlights: • Ca{sub 2}BO{sub 3}Cl doped with Eu{sup 2+} prepared by solid state reaction. • Concentration quenching studied by intensity and lifetime measurements. • Accurate determination of the critical transfer distance. • Interaction mechanism verified to be dipole–dipole interactions. - Abstract: With the aim of determining the concentration quenching mechanism of Eu{sup 2+} doped Ca{sub 2}BO{sub 3}Cl, a series of phosphors with a varied Eu{sup 2+} concentration (Ca{sub 2−x}BO{sub 3}Cl:xEu{sup 2+}) was synthesized by the solid state reaction method. The phase structure was determined by X-ray diffraction. Photoluminescence (PL) measurements showed broad excitation and emission signatures of the allowed f–d transition of Eu{sup 2+} ions. The PL emission intensity was found to be increased by increasing the concentration of Eu{sup 2+} ions up to x = 0.03 and then decreased as a result of the concentration quenching effect. The lifetime of the emission from the Eu{sup 2+} ions was measured and the decrease in the lifetime with increasing Eu{sup 2+} concentration confirmed that non-radiative energy transfer occurred between Eu{sup 2+} ions. From the luminescence data, the value of the critical transfer distance was calculated as 1.5 nm and the corresponding concentration quenching mechanism was verified to be a dipole–dipole interaction.

    The situation regarding food irradiation in France is one of cautious progress, with clearance of specific food items including onions, garlic, shallots, deboned poultry meats and 72 spices. A general clearance for the use of ionizing radiation treatment up to 1 kilogray is under consideration. A most important guiding principle has apparently been accepted in France that no further toxicological studies are required for food irradiation dose levels up to ten kilograys

    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.

    A hierarchical software-defined networking (SDN) control architecture is designed for multi-domain optical networks with the Open Daylight (ODL) controller. The OpenFlow-based Control Virtual Network Interface (CVNI) protocol is deployed between the network orchestrator and the domain controllers. Then, a dynamic bandwidth on demand (BoD) provisioning solution is proposed based on time scheduling in software-defined multi-domain optical networks (SD-MDON). Shared Risk Link Groups (SRLG)-disjoint routing schemes are adopted to separate each tenant for reliability. The SD-MDON testbed is built based on the proposed hierarchical control architecture. Then the proposed time scheduling-based BoD (Ts-BoD) solution is experimentally demonstrated on the testbed. The performance of the Ts-BoD solution is evaluated with respect to blocking probability, resource utilization, and lightpath setup latency.

    Electronic structures of the deep ultraviolet nonlinear optical crystals of the KBe 2 BO 3 F 2 (KBBF) family, including KBBF, RbBe 2 BO 3 F 2 and CsBe 2 BO 3 F 2 , have been investigated based on a plane-wave pseudopotential method. Their linear and nonlinear optical coefficients are also calculated, and are in good agreement with the experimental results. A real-space atom-cutting method is adopted to analyze the respective contributions of the alkali metal cations and anionic groups to optical response. The results show that the contributions of anionic groups to the nonlinear optical anisotropic responses are dominant, but the influence of the A-site alkali metal cations becomes slightly more pronounced with the increase of their radius. Moreover, the birefringence difference among these crystals strongly depends on the volume effect, i.e., the spatial density of the (BO 3 ) 3- anionic groups. (paper)

    BoS(Base of Skull) Frame, the fixation tool which is used for the proton of brain cancer increases the lateral penumbra by increasing the airgap (the distance between patient and beam jet), due to the collision of the beam of the posterior oblique direction. Thus, we manufactured the fixation tool per se for improving the limits of BoS frame, and we'd like to evaluate the utility of the manufactured fixation tool throughout this study. We've selected the 3 patients of brain cancer who have received the proton therapy from our hospital, and also selected the 6 beam angles; for this, we've selected the beam angle of the posterior oblique direction. We've measured the planned BoS frame and the distance of Snout for each beam which are planned for the treatment of the patient using the BoS frame. After this, we've proceeded with the set-up that is above the location which was recommended by the manufacturer of the BoS frame, at the same beam angle of the same patient, by using our in-house Bos frame fixation tool. The set-up was above 21 cm toward the superior direction, compared to the situation when the BoS frame was only used with the basic couch. After that, we've stacked the snout to the BoS frame as much as possible, and measured the distance of snout. We've also measured the airgap, based on the gap of that snout distance; and we've proceeded the normalization based on each dose (100% of each dose), after that, we've conducted the comparative analysis of lateral penumbra. Moreover, we've established the treatment plan according to the changed airgap which has been transformed to the Raystation 5.0 proton therapy planning system, and we've conducted the comparative analysis of DVH(Dose Volume Histogram). When comparing the result before using the in-house Bos frame fixation tool which was manufactured for each beam angle with the result after using the fixation tool, we could figure out that airgap than when not used in accordance with the use of the in-house Bos

  7. Identification of fibroblast growth factor receptor 3 (FGFR3 as a protein receptor for botulinum neurotoxin serotype A (BoNT/A.

    Directory of Open Access Journals (Sweden)

    Birgitte P S Jacky

    Full Text Available Botulinum neurotoxin serotype A (BoNT/A causes transient muscle paralysis by entering motor nerve terminals (MNTs where it cleaves the SNARE protein Synaptosomal-associated protein 25 (SNAP25206 to yield SNAP25197. Cleavage of SNAP25 results in blockage of synaptic vesicle fusion and inhibition of the release of acetylcholine. The specific uptake of BoNT/A into pre-synaptic nerve terminals is a tightly controlled multistep process, involving a combination of high and low affinity receptors. Interestingly, the C-terminal binding domain region of BoNT/A, HC/A, is homologous to fibroblast growth factors (FGFs, making it a possible ligand for Fibroblast Growth Factor Receptors (FGFRs. Here we present data supporting the identification of Fibroblast Growth Factor Receptor 3 (FGFR3 as a high affinity receptor for BoNT/A in neuronal cells. HC/A binds with high affinity to the two extra-cellular loops of FGFR3 and acts similar to an agonist ligand for FGFR3, resulting in phosphorylation of the receptor. Native ligands for FGFR3; FGF1, FGF2, and FGF9 compete for binding to FGFR3 and block BoNT/A cellular uptake. These findings show that FGFR3 plays a pivotal role in the specific uptake of BoNT/A across the cell membrane being part of a larger receptor complex involving ganglioside- and protein-protein interactions.

    Bi 3+ - and RE 3+ -co-doped (Y,Gd)BO 3 phosphors were prepared and their luminescent properties under vacuum ultraviolet (VUV)/UV excitation were investigated. Strong red emission for (Y,Gd)BO 3 :Bi 3+ ,Eu 3+ and strong green emission for (Y,Gd)BO 3 :Bi 3+ ,Tb 3+ are observed under VUV excitation from 147 to 200 nm with a much broader excitation region than that of single Eu 3+ -doped or Tb 3+ -doped (Y,Gd)BO 3 phosphor. Strong emissions are also observed under UV excitation around 265 nm where as nearly no luminescence is observed for single Eu 3+ -doped or Tb 3+ -doped (Y,Gd)BO 3 . The luminescence enhancement of Bi 3+ - and RE 3+ -co-doped (Y,Gd)BO 3 phosphors is due to energy transfer from Bi 3+ ion to Eu 3+ or Tb 3+ ion not only in the VUV region but also in the UV region. Besides, host sensitization competition between Bi 3+ and Eu 3+ or Tb 3+ is also observed. The investigated phosphors may be preferable for devices with a VUV light 147-200 nm as an excitation source such as PDP or mercury-free fluorescent lamp

    A series of blue Na3Gd(BO3)2:Ce3+ and blue-to-green color-tunable Na3Gd (BO3)2:Ce3+,Tb3+ phosphors were synthesized by the solid-state method. The luminescence, concentration quenching and energy transfer (ET) process of Na3Gd(BO3)2:Ce3+,Tb3+ were investigated. Both Ce3+ and Tb3+ occupy the Gd3+ site in the Na3Gd(BO3)2 host. Na3Gd(BO3)2:Ce3+ exhibits strong ultraviolet absorption and broadband blue emission. The Ce3+ sensitization effect on Tb3+ has been verified by the variation of PL/PLE spectra, the Ce3+ decay lifetimes and the energy transfer efficiency of Na3Gd(BO3)2:Ce3+,Tb3+ phosphors. The maximum Ce3+-Tb3+ ET efficiency has been calculated to be 95%. The emitting color of the obtained phosphors can be modulated from blue (0.179, 0.204) through bluish-green (0.271, 0.391) to green (0.349, 0.551) by properly changing the ratio of Ce3+/Tb3+.

    Glucosinolates are a class of amino acid-derived specialized metabolites characteristic of the Brassicales order. Trp derived indolic glucosinolates are essential for the effective plant defense responses to a wide range of pathogens and herbivores. In Arabidopsis, MYB51 is the key transcription factor positively regulates indolic glucosinolate production by activating certain biosynthetic genes. In this study, we report the isolation and identification of a MYB51 from broccoli designated as BoMYB51. Overexpression of BoMYB51 in Arabidopsis increased indolic glucosinolate production by upregulating biosynthetic genes and resulted in enhanced flagellin22 (Flg22) induced callose deposition. The spatial expression pattern and responsive expression of BoMYB51 to several hormones and stress treatments were investigated by expressing the β-glucuronidase (GUS) reporter gene driven by BoMYB51 promotor in Arabidopsis and quantitative real-time PCR analysis in broccoli. Our study provides information on molecular characteristics of BoMYB51 and possible physiological process BoMYB51 may involve. Copyright © 2018 Elsevier Inc. All rights reserved.

    Using the density functional theory (DFT) method, the electronic and mechanical properties of perovskites FeBO3 (B = Ti, Mn, Cr) nanostructures were studied in the pressure range of 0-100 GPa. The band structure studies show the change in the band structure upon substitution of different B cation in FeBO3 perovskite structure. The density of states spectrum gives the perception of change in the electronic properties of FeBO3 with the substitution of B cation. The bulk, shear and Young's moduli were calculated and an increase in the moduli is noticed. Moreover, the hardness increases under high pressure. The high-pressure studies of FeBO3 perovskite nanostructures are explored at atomistic level. The findings show that ductility and hardness of FeBO3 get increased upon an increase in the applied pressure. The substitution of Ti, Mn and Cr on FeBO3 shows a significant change in the electronic and mechanical properties.

  12. [Kidney transplantation epidemiology in France].

    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

    Sphere-like and cauliflower-like hexagonal-vaterite LuBO{sub 3} have been successfully synthesized for the first time via a chemical conversion route using Lu(OH)CO{sub 3} colloid spheres as sacrificial precursor and H{sub 3}BO{sub 3} as boron source without any additional surfactant. FTIR analysis provides an additional evidence of the formation of vaterite-type LuBO{sub 3} in this method. It was found that, an appropriate amount ethanol in the hydrothermal process has a great effect on the products' morphology and crystallinity. Time-dependent experiments indicate that the formation of LuBO{sub 3} crystals went through a two-stage growth process, which involves a fast nucleation of primary particles followed by a slow aggregation and crystallization of primary particles. An investigation on the photoluminescence (PL) properties of LuBO{sub 3}:Eu{sup 3+} phosphors with different morphologies indicates that their PL intensity are dependent on their crystallinity. The effect of Eu{sup 3+} and Tb{sup 3+} doping concentration on PL intensity were also investigated and the quenching concentration of LuBO{sub 3}:Eu{sup 3+} and LuBO{sub 3}:Tb{sup 3+} is 0.25 and 0.20, respectively. Moreover, for Eu{sup 3+}/Tb{sup 3+} doped LuBO{sub 3} phosphors, the color tones can be tuned from green, through green–yellow and yellow, and then to red by simply adjusting the relative doping concentrations of the Tb{sup 3+} and Eu{sup 3+} ions. - Highlights: • Sphere-like and cauliflower-like LuBO{sub 3} were obtained by a conversion route. • This method used Lu(OH)CO{sub 3} and H{sub 3}BO{sub 3} as the precursors for the first time. • Ethanol can control the products' morphology, crystallinity and PL intensity. • The emitting color tones vary with Tb{sup 3+}/Eu{sup 3+} doped concentration.

    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

    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

    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

    PeBoW, a trimeric complex consisting of pescadillo (Pes1), block of proliferation (Bop1), and the WD repeat protein 12 (WDR12), is essential for processing and maturation of mammalian 5.8S and 28S ribosomal RNAs. Applying a mass spectrometric analysis, we identified the DEAD-box helicase DDX27 as stably associated factor of the PeBoW-complex. DDX27 interacts with the PeBoW-complex via an evolutionary conserved F×F motif in the N-terminal domain and is recruited to the nucleolus via its basic C-terminal domain. This recruitment is RNA-dependent and occurs independently of the PeBoW-complex. Interestingly, knockdown of DDX27, but not of Pes1, induces the accumulation of an extended form of the primary 47S rRNA. We conclude that DDX27 can interact specifically with the Pes1 and Bop1 but fulfils critical function(s) for proper 3′ end formation of 47S rRNA independently of the PeBoW-complex. - Highlights: • DEAD-box helicase DDX27 is a new constituent of the PeBoW-complex. • The N-terminal F×F motif of DDX27 interacts with the PeBoW components Pes1 and Bop1. • Nucleolar anchoring of DDX27 via its basic C-terminal domain is RNA dependent. • Knockdown of DDX27 induces a specific defect in 3′ end formation of 47S rRNA.

    Graphical abstract: - Highlights: • Combustion method was employed to synthesize LiMgBO 3 :Dy 3+ nanophosphors. • The phosphor can be efficiently excited by near-UV chips. • XPS was done to investigate the chemical constitution and chemical bonding state of elements in the LiMgBO 3 : Dy 3+ nanophosphor. • The calculated CIE coordinates (0.45, 0.46) were found to be in the white spectrum region. - Abstract: A near-ultra violet (UV) converted LiMgBO 3 :Dy 3+ nanophosphors have been synthesized by the combustion method. The structural, spectral and optical properties were examined by powder X-ray diffraction, fluorescent spectrophotometry and UV–vis spectroscopy. The excitation spectra of the phosphors contain sharp peaks at 294, 323, 348 and 385 nm due to the 4f–4f transition of the Dy 3+ ion. The phosphor is efficiently excited by near-UV chips. Upon near-UV excitation the phosphor emits intense blue and yellow with a weak red band centered at 484, 573 and 669 nm respectively, ascribed to the transition of Dy 3+ ion from 4 F 9/2 → 6 H 15/2 , 6 H 13/2 , 6 H 11/2 . The diffuse reflectance spectra of the phosphors were consistent with the excitation spectra and were used to calculate the band gap of the material, approximated to be 5.4 eV. The calculated CIE coordinates (0.45, 0.46) under 348 nm excitation were found to be in the white spectrum region. For surface investigation, X-ray photoelectron spectroscopy was used which confirms the presence of all the elements on the surface of the material

    Czubek's method of measurement of the thermal neutron absorption cross section may be influenced by the energy spectrum of the thermal neutron flux (deviated from the Maxwellian distribution) which exist in the two-region geometric system. A correction function has been experimentally obtained to eliminate this disturbance. A series of reference measurements has been done on the H 3 BO 3 solution and Plexiglas outer moderator. The obtained function allows to interpret correctly measurements of the thermal neutron absorption rate in the range from 10 000 to 45 000 s -1 for hydrogenous samples. (author)

    We report the microscopic magnetic model for the spin-1/2 Heisenberg system CdCu2(BO3)2, one of the few quantum magnets showing the 1/2-magnetization plateau. Recent neutron diffraction experiments on this compound [M. Hase , Phys. Rev. BPLRBAQ0556-280510.1103/PhysRevB.80.104405 80, 104405 (2009)] evidenced long-range magnetic order, inconsistent with the previously suggested phenomenological magnetic model of isolated dimers and spin chains. Based on extensive density functional theory band structure calculations, exact diagonalizations, quantum Monte Carlo simulations, third-order perturbation theory as well as high-field magnetization measurements, we find that the magnetic properties of CdCu2(BO3)2 are accounted for by a frustrated quasi-2D magnetic model featuring four inequivalent exchange couplings: the leading antiferromagnetic coupling Jd within the structural Cu2O6 dimers, two interdimer couplings Jt1 and Jt2, forming magnetic tetramers, and a ferromagnetic coupling Jit between the tetramers. Based on comparison to the experimental data, we evaluate the ratios of the leading couplings Jd : Jt1 : Jt2 : Jit = 1 : 0.20 : 0.45 : -0.30, with Jd of about 178 K. The inequivalence of Jt1 and Jt2 largely lifts the frustration and triggers long-range antiferromagnetic ordering. The proposed model accounts correctly for the different magnetic moments localized on structurally inequivalent Cu atoms in the ground-state magnetic configuration. We extensively analyze the magnetic properties of this model, including a detailed description of the magnetically ordered ground state and its evolution in magnetic field with particular emphasis on the 1/2-magnetization plateau. Our results establish remarkable analogies to the Shastry-Sutherland model of SrCu2(BO3)2, and characterize the closely related CdCu2(BO3)2 as a material realization for the spin-1/2 decorated anisotropic Shastry-Sutherland lattice.

    The electronic and optical properties of TbAl3(BO3)4 are determined using density functional theory. The calculated total magnetic moment of 5.96 μB is close to the expected moment of Tb3+. The frequency dependent dielectric function, refractive index, extinction coefficient, absorption, optical reflectivity, and energy loss function are explained in terms of the transitions between the valence and conduction bands. We find very high Kerr angles for ultraviolet light and potential for extension, even into the visible range by band structure design.

  1. Tunable Yellow-Red Photoluminescence and Persistent Afterglow in Phosphors Ca4LaO(BO3)3:Eu3+ and Ca4EuO(BO3)3.

    In most Eu 3+ activated phosphors, only red luminescence from the 5 D 0 is obtainable, and efficiency is limited by concentration quenching. Herein we report a new phosphor of Ca 4 LaO(BO 3 ) 3 :Eu 3+ (CLBO:Eu) with advanced photoluminescence properties. The yellow luminescence emitted from the 5 D 1,2 states is not thermally quenched at room temperature. The relative intensities of the yellow and red emission bands depend strongly on the Eu 3+ doping concentration. More importantly, concentration quenching of Eu 3+ photoluminescence is absent in this phosphor, and the stoichiometric compound of Ca 4 EuO(BO 3 ) 3 emits stronger luminescence than the Eu 3+ doped compounds of CLBO:Eu; it is three times stronger than that of a commercial red phosphor of Y 2 O 3 :Eu 3+ . Another beneficial phenomenon is that ligand-to-metal charge transfer (CT) transitions occur in the long UV region with the lowest charge transfer band (CTB) stretched down to about 3.67 eV (∼330 nm). The CT transitions significantly enhance Eu 3+ excitation, and thus result in stronger photoluminescence and promote trapping of excitons for persistent afterglow emission. Along with structure characterization, optical spectra and luminescence dynamics measured under various conditions as a function of Eu 3+ doping, temperature, and excitation wavelength are analyzed for a fundamental understanding of electronic interactions and for potential applications.

  2. Molecular Characterization of the First Bovine Herpesvirus 4 (BoHV-4 Strains Isolated from In Vitro Bovine Embryos production in Argentina.

    Directory of Open Access Journals (Sweden)

    Erika González Altamiranda

    Full Text Available Bovine herpesvirus 4 (BoHV-4 is increasingly considered as responsible for various problems of the reproductive tract. The virus infects mainly blood mononuclear cells and displays specific tropism for vascular endothelia, reproductive and fetal tissues. Epidemiological studies suggest its impact on reproductive performance, and its presence in various sites in the reproductive tract highlights its potential transmission in transfer-stage embryos. This work describes the biological and genetic characterization of BoHV-4 strains isolated from an in vitro bovine embryo production system. BoHV-4 strains were isolated in 2011 and 2013 from granulosa cells and bovine oocytes from ovary batches collected at a local abattoir, used as "starting material" for in vitro production of bovine embryos. Compatible BoHV-4-CPE was observed in the co-culture of granulosa cells and oocytes with MDBK cells. The identity of the isolates was confirmed by PCR assays targeting three ORFs of the viral genome. The phylogenetic analyses of the strains suggest that they were evolutionary unlinked. Therefore it is possible that BoHV-4 ovary infections occurred regularly along the evolution of the virus, at least in Argentina, which can have implications in the systems of in vitro embryo production. Thus, although BoHV-4 does not appear to be a frequent risk factor for in vitro embryo production, data are still limited. This study reveals the potential of BoHV-4 transmission via embryo transfer. Moreover, the high variability among the BoHV-4 strains isolated from aborted cows in Argentina highlights the importance of further research on the role of this virus as an agent with the potential to cause reproductive disease in cattle. The genetic characterization of the isolated strains provides data to better understand the pathogenesis of BoHV-4 infections. Furthermore, it will lead to fundamental insights into the molecular aspects of the virus and the means by which these

    Full Text Available Caprine herpesvirus type 1 (CpHV-1 is an alphaherpesvirus causing genital disease leading to abortion in adult pregnant goats and a systemic disease with high morbility and mortality in kids. Further, Caprine herpesvirus 1 infection represents a valuable large animal model for human herpesvirus induced genital disease, exploitable for pathogenic studies, new vaccines and antiviral molecules testing. Here, the bovine herpesvirus 4 (BoHV-4 based vector derived from an apathogenic isolate of BoHV-4 and expressing the immunodominant CpHV-1 glycoprotein D (BoHV-4-A-gD(cpgD(106ΔTK was constructed and its ability to protect goats against CpHV-1 induced genital disease evaluated. The subcutaneous route of recombinant BoHV-4 administration was first tested in vivo/ex vivo by in vivo image analysis and in vitro by goat skin primary cultures preparation and transduction. Next, an exploratory immunization and safety study in goats was performed with two recombinant BoHV4, BoHV-4-A-gD(cpgD(106ΔTK or BoHV-4-CMV-IgK-gE2gD-TM. In both cases no clinical signs were evident but a good titer of serum neutralizing antibodies was produced in all inoculated animals. When a challenge experiment was performed in a new group of animals using a highly pathogenic dose of CpHV-1, all the vaccinated goats with BoHV-4-A-gD(cpgD(106ΔTK were protected toward CpHV-1 induced genital disease respect to the unvaccinated control which showed typical vaginal lesions with a high grade of clinical score as well as a long lasting viral shedding. In summary, the data acquired in the present study validate BoHV-4-based vector as a safe and effective viral vector for goat vaccination against CpHV-1 induced genital disease and pave the way for further applications.

    Both Zr-codoped Lu 0.8 Sc 0.2 BO 3 :Ce polycrystalline powders and single crystals were obtained by solid-state reaction and Czochralski method, respectively. The effects of Zr codoping on the optical absorption, Ce 3+ /Ce 4+ ratio, scintillation efficiency, decay time and point defect in Lu 0.8 Sc 0.2 BO 3 :Ce materials were examined systematically. Our results show that there is no positive contribution of Zr 4+ ion codoping to the scintillation efficiency. And the reasons for the deterioration of scintillation efficiency by codoping Zr 4+ were revealed. - Highlights: ► No positive contribution of the Zr 4+ ions on the scintillation efficiency was found. ► New optical absorption band was in the region from 200 to 225 nm. ► Continuously accelerated decay time indicated that Zr 4+ codoping induced new point defects. ► The induced hole trap located at 1.91 eV below the conduction band.

    LiBO 2 glass scintillators were fabricated, and lanthanides(except Pm) oxides or chlorides were used as an activator. For the fabrication of LiBO 2 glasses, optimum heating conditions were obtained, and the photoluminescence of the glasses was measured by the monochromator. For the best transparency of the glass samples, optimum heating temperature and time are 1000 .deg. C and 40 min, respectively. The result of photoluminescence analysis shows that Pr, Nd, Gd, Ho, Er, Tm, Yb, and Lu are not good as activator. Because emission spectrum of samples with them was equal to that of sample without activator. In the case of samples with Europium, the peak of emission spectrum of Eu(III) is 810 nm. And Samples with Ce(III) are 760 nm, and Tb(III) are about 535 nm. Samples with Ce(III) and Tb(III) have the best PL intensity with added sugar in Ar reduction atmosphere, and sample with Eu(III) has the best intensity without a reducing process

    2016-04-01

    BO2-substituted B3N3C54 heterofullerene was studied using density functional theory, and its electronic, magnetic and nonlinear optical properties are discussed. The substitution was considered at the B and N sites of the heterofullerene, in lower and higher spin states. We notice that BO2 substitution at the B sites of B3N3C54 heterofullerene leads to interesting properties, such as a smaller energy gap (0.66 eV) and a high spin magnetic moment (3 μ B). The density-of-states curves, molecular orbitals and spin density surfaces have been used to explain these facts. In addition, the first-order mean hyperpolarizability of B3N3C54 heterofullerene has been found to be significantly large (3.6 × 103 a.u.), which is due to smaller transition energy in the crucial excited state. This is reflected by the absorption spectra calculated using the time-dependent density functional theory method. These findings may be exploited to design novel materials for possible spintronic and electro-optical applications.

    The first 16 valence electron [bis(NHC)](silylene)Ni 0 complex 1, [( TMS L)ClSi:→Ni(NHC) 2 ], bearing the acyclic amido-chlorosilylene ( TMS L)ClSi: ( TMS L=N(SiMe 3 )Dipp; Dipp=2,6-Pr i 2 C 6 H 4 ) and two NHC ligands (N-heterocyclic carbene=:C[(Pr i )NC(Me)] 2 ) was synthesized in high yield and structurally characterized. Compound 1 is capable of facile dihydrogen activation under ambient conditions to give the corresponding HSi-NiH complex 2. Most notably, 1 reacts with catechol borane to afford the unprecedented hydroborylene-coordinated (chloro)(silyl)nickel(II) complex 3, {[cat( TMS L)Si](Cl)Ni←:BH(NHC) 2 }, via the cleavage of two B-O bonds and simultaneous formation of two Si-O bonds. The mechanism for the formation of 3 was rationalized by means of DFT calculations, which highlight the powerful synergistic effects of the Si:→Ni moiety in the breaking of incredibly strong B-O bonds. © 2017 Wiley-VCH Verlag GmbH & Co.

    The study of interacting spin systems is of fundamental importance for modern condensed-matter physics. On frustrated lattices, magnetic exchange interactions cannot be simultaneously satisfied, and often give rise to competing exotic ground states. The frustrated two-dimensional Shastry-Sutherland lattice realized by SrCu2(BO3)2 (refs ,) is an important test case for our understanding of quantum magnetism. It was constructed to have an exactly solvable 2-spin dimer singlet ground state within a certain range of exchange parameters and frustration. While the exact dimer state and the antiferromagnetic order at both ends of the phase diagram are well known, the ground state and spin correlations in the intermediate frustration range have been widely debated. We report here the first experimental identification of the conjectured plaquette singlet intermediate phase in SrCu2(BO3)2. It is observed by inelastic neutron scattering after pressure tuning to 21.5 kbar. This gapped singlet state leads to a transition to long-range antiferromagnetic order above 40 kbar, consistent with the existence of a deconfined quantum critical point.

    The molecular mechanism of proton pumping by heme-copper oxidases (HCO) has intrigued the scientific community since it was first proposed. We have recently reported a novel technology that enables the continuous characterisation of proton transport activity of a HCO and ubiquinol oxidase from...... Escherichia coli, cytochrome bo3, for hundreds of seconds on the single enzyme level (Li et al. J Am Chem Soc 137 (2015) 16055–16063). Here, we have extended these studies by additional experiments and analyses of the proton transfer rate as a function of proteoliposome size and pH at the N- and P......-side of single HCOs. Proton transport activity of cytochrome bo3 was found to decrease with increased curvature of the membrane. Furthermore, proton uptake at the N-side (proton entrance) was insensitive to pH between pH 6.4–8.4, while proton release at the P-side had an optimum pH of ~ 7.4, suggesting...

  8. The Future of the CEMAC CFA Franc

    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)

By that particular acquisition, this prominent publisher originating from Zeta has visualized his new position in the sixteenth century Venice. The multi-layered identity of Božidar Vuković was manifested by the subsequent inclusion of the noble coat of arms of the House of Vuković on the back of the icon. By the use of verbal and visual language the artificial initiation of Božidar Vuković within the distinguished members of Venetian society has been confirmed.

    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

Nevertheless, here we demonstrate a new Eu 2+ /Eu 3+ coactivated SrAl 3 BO 7 nanocrystalline phosphor with abundant and excellent multichannel luminescence properties. A series of Eu 2+ /Eu 3+ coactivated SrAl 3 BO 7 nanocrystalline phosphors were prepared through a Pechini-type sol-gel method followed by a reduction process. With excitation of UV/NUV light, the prepared SrAl 3 BO 7 :Eu 2+ ,Eu 3+ phosphors show not only the characteristic f-f transitions of Eu 3+ ion ( 5 D J → 7 F J,J' , J, J' = 0-3), but also the 5d → 4f transitions of Eu 2+ ion with comparable intensity from 400 to 700 nm in the whole visible spectral region. The luminescence color of the SrAl 3 BO 7 :Eu 2+ ,Eu 3+ phosphor can be tuned from blue, blue-green, white, and orange to orange-red by changing the excitation wavelength, the overall doping concentration of europium ions (Eu 2+ , Eu 3+ ), and the relative ratio of Eu 2+ to Eu 3+ ions to some extent. A single-phase white-light emission has been realized in SrAl 3 BO 7 :Eu 2+ ,Eu 3+ phosphor. The obtained SrAl 3 BO 7 :Eu 2+ ,Eu 3+ phosphor has potential application in the area of NUV white-light-emitting diodes.

    The investigation of mixed Co-Fe ludwigite single crystals shows that their magnetic properties are close to the magnetic properties of Fe3BO5 despite the predominance of cobalt ions. The magnetic properties of Co3 - x Fe x BO5 single crystals with x = 0.10 are studied in detail. Magnetometric measurements demonstrate a strong magnetic anisotropy with easy magnetization axis b, and the orbital magnetic moment of cobalt is in a frozen state. The detected temperature dependence of the absorption of Mössbauer spectra allowed us to determine the magnetic ordering temperature, which agrees with the results of magnetization measurements ( T C = 84 K).

    The present work investigated the effect of coprecipitation-oxidant synthesis on the specific surface area of perovskite-type oxides LaBO{sub 3} (BMn, Ni, Fe) for total oxidation of ethanol. The perovskite-type oxides were characterized by X-ray diffraction, nitrogen adsorption (BET method), thermogravimetric analysis (TGA-DTA), TPR and X-ray photoelectron spectroscopy (XPS). Through method involving the coprecipitation-oxidant was possible to obtain catalysts with different BET specific surface areas, of 33-51 m{sup 2}/g. The results of the catalytic test confirmed that all oxides investigated in this work have specific catalytic activity for total oxidation of ethanol, though the temperatures for total conversion change for each transition metal.

  11. Second births in western Germany and France

    Directory of Open Access Journals (Sweden)

    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.

    2005-12-01

    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

  16. 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.

    Over the course of the next few years, France will have to renew its nuclear arsenal to ensure that it remains a credible deterrent in the eyes of its potential enemies. This update must occur within an unfavourable context: the strategic environment, marked by the multiplication of Jihadi fronts, has deteriorated, and budgetary discipline is the order of the day. Sacrificing nuclear deterrence at the altar of the fight against terrorism would, however, be a fatal error

    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.

  9. Insurance of the Nuclear Risk in France

    International Nuclear Information System (INIS)

    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)

  11. Offshore wind power: does France remain ashore?

    International Nuclear Information System (INIS)

    Bongrain, T.

    2015-01-01

    France benefits from favorable geographical conditions for offshore wind power but the development of a dedicated industrial sector is slow. 6 projects of wind power farms where turbines are rooted in the seabed are expected to operate progressively from 2018, they represent a cumulated power capacity of 2920 MW. A call for projects has been launched by French authorities for floating offshore wind farms off Brittany and in the mediterranean sea but it will not be sufficient to help to fulfill the declared goal of 40% of the electricity produced in France should be of renewable origin. The main weakness is the cost and countries like Germany benefit from the shallow waters of the North sea to install wind farms at lower costs. The solution could be the development in France of an industrial sector dedicated to floating wind turbines that are easier to install in deep water and can be settled farther off the coast to meet the demand of environmentalists for seascape preservation. More sites could become available for floating wind turbines than for seabed-rooted ones and as the consequence the market for floating systems may become more important. (A.C.)

  13. A decade of nuclear development in France

    International Nuclear Information System (INIS)

    Renon, G.

    1984-01-01

    After the first energy crisis, in France depended heavily on oil import, the broad lines of strategy were the improvement of efficiency in energy use, the diversification of energy sources and the development of domestic substitute energy sources. The energy conservation policy achieved in 1983 up to 35 million tons of oil equivalent saving. The coal and natural gas output in France decreased during the last ten years, but the national energy production covered 38.7 % of the national needs in 1983. This result is mainly due to the implementation of electro-nuclear program whose contribution to the total energy consumption was more than 17 % in 1983. In 10 reference years, 29 PWR units of 900 MWe and 17 PWR units of 1300 MWe have been launched, and 27 units of 900 MWe each have been commissioned. The power cost per kWh generated by nuclear energy remained about 2/3 of that by coal. The cumulative production of 900 MWe PWRs is already equivalent to 50 reactor-years at full power. The average availability of the units was 68 % in 1983, which showed that the problems have been solved. Also the state of nuclear fuel cycle in France, the trend of reactor improvement and the long term plan are explained. (Kako, I.)

    The first known use of tidal power in France concerns the tidal mills in general use during the Middle Age along the French coasts. The first research studies of tidal power plants started at the end of the first world war but it is only in 1940 with the stimulus of Robert Gibrat that was created the Research Society for the use of Tides and the Rance plant project. In 1946, Electricite de France (EdF) started again the studies of this company for a greater size project in the Chausey archipelago which was abandoned for the benefit of the Rance project in the 1960's. The start up of the plant took place in 1967 but the other projects were abandoned during the 1980's. This short paper recalls the historical aspects of the development of tidal power in France and focusses on the research and development studies and on the economical, political and legal factors that led to retain the Rance project among others proposed.

    Hantaviral infections causing hemorrhagic fever with renal syndrome are endemic in North Eastern France. Humans are contaminated by the inhalation of aerosols contaminated by rodent faeces. In February 2003, the National reference centre (NRC) for hemorrhagic fevers detected an increased number of cases. An investigation was carried out to confirm the outbreak and take appropriate control measures. Cases were collected by the NRC. A case was defined as a person living in France with symptoms compatible with hantaviral infection and a positive blood test both for specific Puumala IgM, and IgG. Clinical information and at-risk exposures during the 2 weeks before onset were recorded. In 2003, 128 cases were diagnosed (61 in 2002). The median age of patients was 38, 77% were men and 82% were hospitalized. Patients were living in North-Eastern France. Clusters were detected in the Ardennes and Oise districts. Occupation (35%) (in agriculture, forestry, and construction work), manipulation of firewood (35%), gardening (29%), and outdoors leisure (14%) were identified as at-risk exposures in these cases. An increased number of positive diagnoses of hantaviral infections was confirmed. The location and at-risk exposures of the cases were identical in previous investigations. Exclusion and prevention of rodents' access to houses and avoiding the inhalation of contaminated dust are the only possible prevention measures of hantaviral infections. Information about the disease and its prevention needs to be made widely available to both healthcare professionals and the general population living in endemic areas.

    The bovine MHC (BoLA) class II DRB3 alleles are associated with polyclonal expansion of lymphocytes caused by bovine leukemia virus (BLV) infection in cattle. To examine whether the DRB3*0902 allele, one of the resistance-associated alleles, is associated with the proviral load, we measured BLV proviral load of BLV-infected cattle and clarified their DRB3 alleles. Fifty-seven animals with DRB3*0902 were identified out of 835 BLV-infected cattle and had significantly lower proviral load (Pclass II DRA/DRB3*0902 molecule plays an important immunological role in suppressing viral replication, resulting in resistance to the disease progression.

    Full Text Available Raman spectra of Ho1−xNdxFe(BO34 (x=1, 0.75, 0.5, 0.25 have been studied in temperature range 10–400K. Two compositions (x=1, x=0.75 demonstrate structural phase transition with soft mode restoration. The addition of Nd atoms increases interatomic spacing and decreases the temperature of structural phase transition. The solid solutions (x=0.75, 0.5, 0.25 demonstrate the emergence of the peaks corresponding to magnetoelastic interaction below Néel temperature. The order parameter of the magnetic phase transition has been determined. The equal concentrations of holmium and neodymium atoms prevent magnon soft modes condensation caused by exchange interactions in Fe–O–Fe chains are observed. Calculations confirm the data obtained in the experiment.

    Full Text Available Rare-earth calcium oxyborate crystals, ReCa4O(BO33 (ReCOB, Re = Er, Y, Gd, Sm, Nd, Pr, and La , are potential piezoelectric materials for ultrahigh temperature sensor applications, due to their high electrical resistivity at elevated temperature, high piezoelectric sensitivity and temperature stability. In this paper, different techniques for ReCOB single-crystal growth are introduced, including the Bridgman and Czochralski pulling methods. Crystal orientations and the relationships between the crystallographic and physical axes of the monoclinic ReCOB crystals are discussed. The procedures for dielectric, elastic, electromechanical and piezoelectric property characterization, taking advantage of the impedance method, are presented. In addition, the maximum piezoelectric coefficients for different piezoelectric vibration modes are explored, and the optimized crystal cuts free of piezoelectric cross-talk are obtained by rotation calculations.

    This paper reports on the emission analysis of a green luminescent Tb 3+ :Ca 4 GdO(BO 3 ) 3 powder phosphor based on the measurements of excitation, emission and lifetimes. Besides this, we have also observed an intense green emission from this powder phosphor under an UV source. The emission transitions of ( 5 D 4 →7 F 3,4,5,6 ) with λ exci =257 nm have been measured. Particularly, the green emission transition ( 5 D 4 →7 F 5 ) at 553 nm has been found to be more prominent and intense. Such green strong emission displaying powder phosphor will find applications in the development of coated screens in certain electronic systems. Apart from the emission analysis of this phosphor, XRD, SEM and FTIR studies have also been carried out in order to understand the structural details of it

    In this study we have investigated the low-dimensional correlated spin system SrCu2(BO3)2 using ambient-pressure muon spin rotation/relaxation (μ+SR). The zero-field data are similar to previously published data, but in addition, they give an even clearer sign of the two low-temperature transitions (T1 ≈ 3 and T2 ≈ 7 K), which is fully consistent with inelastic neutron scattering (INS) measurements. Longitudinal field (LF) data clearly show that the copper spins are highly dynamic and a saturation of the low-temperature relaxation rate indicate that these are indeed two-dimensional (2D) quantum spin fluctuations.

    The objective fixed by the European Commission in 1995 was that 5% of the fuel used for transport in Fance should be produced from renewable energy by 2005. As opposed to some other European countries, there is no environmental tax on fossil fuels in France, but the Government has agreed to a tax incentive system on biofuels. Experimental work on liquid biofuels as a transport fuel started in France in the early 80's, but the use of biofuels on a commercial basis really started to develop when the setaside rules and tax incentives came into force in 1991. Out of the two routes originally considered for development; bioethanol and its ETBE derivative, and vegetable oils and their methyl ester derivatives, priority has now been given to: ETBE produced from sugar beet and wheat and now from sub-products of starch industry, which are widely grown in France; ETBE is blended with gasoline for use in spark ignition engines. Production of wheat and beet for energy purposes is very similar to food production. In France, ethanol produce from sugar beet is a traditional industry; this was the first route to be developed. The results of a life cycle analysis made for ETBE produce from sugar beet will be given, showing advantages and limitations. Alcohol produced from wheat is a more recent activity; two industrial plants have been built since beginning of the 90's and other projects are planned like for example a production from starch industry. RME (rapeseed methyl ester) for use in diesel engines at various blend rates. Vegetable oils or their derivatives such as esters can be used directly in diesel engines. Pure, filtered and degummed oils can be used in pre-chamber engines. Relatively advanced knowledge has now been gained about esters; because their characteristics are very similar to those of conventional diesel fuel, they are considered suitable for use in direct injection diesel engines without engine modification. In France, methyl ester is at present produced mainly

    A novel Ce 3+ /Eu 2+ co-activated LiSr 4 (BO 3 ) 3 phosphor has been synthesized by traditional solid-state reaction. The samples could display varied color emission from blue towards white and ultimately to yellow under the excitation of ultraviolet (UV) light with the appropriate adjustment of the relative proportion of Ce 3+ /Eu 2+ . The resonance-type energy transfer mechanism from Ce 3+ to Eu 2+ in LiSr 4 (BO 3 ) 3 :Ce 3+ , Eu 2+ phosphors is dominant by electric dipole–dipole interaction, and the critical distance is calculated to be about 29.14 Å by the spectra overlap method. White light was observed from LiSr 4 (BO 3 ) 3 :mCe 3+ , nEu 2+ phosphors with chromaticity coordinates (0.34, 0.30) upon 350 nm excitation. The LiSr 4 (BO 3 ) 3 :Ce 3+ , Eu 2+ phosphor has potential applications as an UV radiation-converting phosphor for white light-emitting diodes. - Highlights: ► White light was observed from the novel phosphor with chromaticity coordinate (0.34, 0.30). ► Resonant energy transfer between Ce 3+ and Eu 2+ occurs in the novel phosphor. ► This novel phosphor has potential applications as a UV-driven light-emitting phosphor.

    Boñar Formation (Upper Cretaceous) is a mainly carbonate succession, which outcrops in the North of Duero Basin (Spain). According to the existing data, the Dolomitic Member of this formation appears to be the most suitable for geological storage of CO2. The main objective of this study is to find evidence to support, clarify and specify –at an initial level– the potential of the Dolomitic Member of the Boñar Formation as a geological reservoir. The study covers density, porosity and permeability tests on samples obtained from the outcrop of the succession near the village of Boñar (León). According to the analysis and interpretation of the mentioned petrophysical properties, the porosity of the Dolomitic Member is within the acceptable range for CO2 geological storage, but the permeability values are far too low. This minimizes the possibilities of the Dolomitic Member –and probably of the whole Boñar Formation– to become an appropriate CO2 reservoir. (Author)

    Investigations were performed to localize and analyze the botulinum toxin (BoNT-A) related changes of cerebral cortex activation in chronic stroke patients suffering from severe hand paralysis with arm spasticity. Effects on task- related cerebral activation were evaluated by functional magnetic resonance imaging (fMRI). 14 patients (5 males, 9 females, mean age 55.3 years) suffering from upper limb post-stroke spasticity were investigated. The change of arm spasticity was assessed by using the modified Ashworth scale (MAS). FMRI sessions were performed before (W0), four weeks (W4) and 11 weeks (W11) after BoNT-A application. Patients were scanned while performing imaginary movement with the impaired hand. Group fMRI analysis included patient age as a covariate. BoNT-A treatment was effective in alleviation of arm spasticity. Mean MAS was at Week 0: 2.5 (SD 0.53), at Week 4: 1.45 (SD 0.38), at Week 11: 2.32 (SD 0.44). Task-related fMRI prior to the treatment showed extensive activation of bilateral frontoparietal sensorimotor cortical areas, anterior cingulate gyrus, pallidum, thalamus and cerebellum. Effective BoNT-A treatment (W4) resulted in partial reduction of active network volume in most of the observed areas, whereas BoNT-free data (W11) revealed further volume reduction in the sensorimotor network. On direct comparison, significant activation decreases associated with BoNT-A treatment were located in areas outside the classical sensorimotor system, namely, ipsilesional lateral occipital cortex, supramarginal gyrus and precuneus cortex. On comparison of W4 and W11, no activation increases were found, instead, activation further decreased in ipsilesional insular cortex, contralesional superior frontal gyrus and bilateral frontal pole. Whole brain activation patterns during BoNT-A treatment of post-stroke arm spasticity and further follow up document predominantly gradual changes both within and outside the classical sensorimotor system.

    The Board of Directors of Gaz de France approved the Group's consolidated accounts for 2004. In a more dynamic economic environment than in 2003, the Gaz de France Group reports enhanced results and has continued to pursue its growth in Europe. Increase in net sales driven by sustained growth in sales (+ 8.9%): In 2004, net sales rose 8.9% compared with the 2003 financial year to reach a total of euro 18,129 m. This strong increase in business activities was driven by sustained growth in sales volumes both in France and Europe. Total Group sales volumes amounted to 730 TWh (approximately 66 billion cubic metres), equal to growth of 10.3%. Natural gas sales volumes increased by approximately 10% in France, and are almost 18% higher in Europe, notably in the United Kingdom, Italy, Belgium and the Netherlands. The Group has pursued the profitable development of its activities outside France. As a result, international activities account for 29% of total sales in 2004, against 23% in 2003. The contribution made by international subsidiaries - particularly those specializing in exploration and production - grew by a very substantial 44.3% to reach a total of euro 502 m in 2004. Energy and Services Offering Branch: this core business line, which includes natural gas and oil exploration and production, energy trading and sales, and services associated with the supply of energy, boasts net sales of euro 16,498 m, equal to growth of 10.8% compared with 2003. Infrastructures Branch: this division, which groups together all activities related to the management of transmission and distribution infrastructures in both the French domestic and international markets, generated net sales of euro 6,794 m in 2004, virtually unchanged from the previous year. This situation is the result of higher sales generated by the distribution subsidiaries operating outside France (+9.2%) offset by a decline in the sales performance of the Transmission, Storage and Distribution in France

    A series of novel red-emitting phosphors BaAlBO{sub 3}F{sub 2}:xEu{sup 3+} (0.001≤x≤0.08) were first synthesized via a high temperature solid-state reaction. X-ray diffraction and photoluminescence spectroscopy were used to characterize the crystal structure and photoluminescence properties of the phosphor, respectively. The phosphor can be effectively excited with a 395 nm light, and shows a dominant {sup 5}D{sub 0}−{sup 7}F{sub 2} emission with chromatic coordination of 0.628 and 0.372. The optimal doping concentration is about 0.04. Rietveld refinement results and the luminescence behavior of Eu{sup 3+} indicate that the Eu{sup 3+} ion occupies a C{sub 3} symmetry site, and the host BaAlBO{sub 3}F{sub 2} has a hexagonal structure with P-6 space group. In addition, the phosphor could be a potential candidate as red-emitting phosphor for application in white light-emitting diode. - Graphical abstract: The luminescence behavior and Rietveld refinement of BaAlBO{sub 3}F{sub 2}:Eu{sup 3+} indicate that the red-emitting phosphor has potential application in white LED and the host has a hexagonal structure with P-6 space group. - Highlights: • A novel red-emitting phosphor BaAlBO{sub 3}F{sub 2}:Eu{sup 3+} is first synthesized. • The crystal structure of BaAlBO{sub 3}F{sub 2} is confirmed. • The phosphor shows potential application in white LED.

    The development of the program for the production of transplutonium elements, 241 Am, 243 Am and 244 Cm, in France, required a major effort from the technological and chemical standpoints. Pre-existing hot cells were reconditioned and others specially built for these production operations. From the chemical standpoint, the development of extractive chromatography on the preparative scale has allowed the definition of simple processes. This type of process, initially developed for the treatment of Pu/Al targets, is ideal for the treatment of industrial wastes for their decontamination and for the production of 241 Am

    A national survey on environmental nuisances due to all forms of transport was made in France during 1977. From among the data gathered, it is possible to extract results concerning the impact of nuisance due to railways, partly from results of questionnaires and partly from results of acoustical measurements. Interviews and measurements were made in several towns, at randomly selected dwellings. Rail and air transport noise nuisance impacts appeared to be of comparable importance, with that of road transport very much larger than either. (0 refs).

  11. Energy consumption in France's industry. Conjuncture note

    2015-04-01

    Energy consumption in the industry represents today 1/5 of France's end-use energy consumption. Gas and electricity are the most consumed and represent 2/3 of the overall. The 5 most energy consuming industries are the following: paper and cardboard industry, food industry, rubber, plastic and other non-metallic mineral products industry, metallurgy and chemical industry. The reduction of the industry's energy consumption is explained by the decline of production, but above all by the energy efficiency improvement of the sector. Technological innovations in production means have indeed led to reduce energy consumption

    The service life of a nuclear power plant is linked to good operating and maintenance practices and effective management which should begin when the plant starts operating. In France the construction of two series of virtually identical reactors has enabled Framatome to use feedback from early units to modify and improve later ones. The intention is to keep the plants safe and to extend life as far into the next century as is feasible. Remedial measures that can be applied include improvements to plant operation itself, plant modifications and the implementation of effective preventive and corrective maintenance operations which may cover planned provision for the replacement of obsolete or susceptible components.

    Claims about the health risks posed by nuclear-power installations are always controversial, but nowhere more so than in France, where some 75% of the nation's electricity is generated from nuclear energy. So, it was no surprise that publication of a study by two French epidemiologists earlier this month claiming to show a link between cases of childhood leukemia and the nuclear-waste reprocessing plant at La Hague on the Normandy coast sparked fireworks in the French press. Several French epidemiologists sharply criticized the study's methodology and conclusions. Their attacks have now drawn an unusual response from the British Medical Journal (BMJ), in which the paper appeared

  16. Electricity prices differences between France and Germany

    Hensing, I.; Nolden, A.; Riechmann, Ch.; Schulz, W.

    1998-01-01

    High electricity prices in Germany especially as compared to France have played an important role in the electricity liberalization debate in Germany. The price differences can largely be explained by cost differences in electricity generation, the electricity grids, personnel cost and local taxes. Further analysis suggests that efficiency improvements upon market liberalization will only partly remove these price and cost differentials. Parts of the cost differentials are attributable to politically-motivated regulations and the (future) regulation of network functions. This implies that Germany can only expect to arrive at internationally comparable electricity prices if it advances with a reform of political and monopoly regulations alongside liberalizing electricity generation and trade.

    Classification of radioactive wastes customary in France and the program of radiation protection in handling them are discussed. Various methods of radioactive waste processing and burial are considered. The French classification of radioactive wastes differs from one used in the other countries. Wastes are classified under three categories: A, B and C. A - low- and intermediate-level radioactive wastes with short-lived radionuclides (half-life - less than 30 years, negligible or heat release, small amount of long-lived radionuclides, especially such as plutonium, americium and neptunium); B - low- and intermediate-level radioactive wastes with long-lived radionuclides (considerable amounts of long-lived radionuclides including α-emitters, low and moderate-level activity of β- and γ-emitters, low and moderate heat release); C - high-level radioactive wastes with long-lived radionuclides (high-level activity of β- and γ-emitters, high heat release, considerable amount of long-lived radionuclides). Volumetric estimations of wastes of various categories and predictions of their growth are given. It is noted that the concept of closed fuel cycle with radiochemical processing of spent fuel is customary in France

    2004-01-01

    Following an overview of the specific features of the European gas sector (characterised by highly concentrated production and increasing levels of production outside Europe and over long distances), the article describes the lead up to the opening of the market place in France. Following the application of the first directive in 2000, Gaz de France has carried out various measures, the aim of which was to achieve immediate efficiency (with the organizational separation of the transport and trading divisions, the separation of activities from an accounting viewpoint and the publication of a transparent TPA tariff as opposed to a discriminatory one). This opening of the gas sector has seen the start of a gradual process based on this experience. In addition to these initial measures, the opening of the gas markets has been subject to a regulatory framework as from January 2003, and the task of regulating the French gas sector has been given to the CRE (Commission de regulation de l'electricite). Thanks to the ongoing dialogue initiated by the latter with all key players in the market, progress has been achieved in various fields related to regulation. Even if this process is not complete, the French example demonstrates that the combined actions of the regulator and the market operators working together in a constructive manner and in stages, makes it possible to successfully introduce a genuinely open market.

  9. The Dismantling of Nuclear Installations in France

    International Nuclear Information System (INIS)

    Bonnaure, P.

    2011-01-01

    As we saw in the previous article by Pierre Bonnaure, though it has long been decried for the dangers inherent in its production structures and the very long-lived waste that it generates, nuclear power may yet recover its credibility, particularly in France. However, on close examination, we see that the nuclear industry is beset by a number of unresolved questions, beginning with the dismantling of installations that have become obsolete or are set to become so. Nuclear power took off after the Second World War, but several generations of technology have been developed since then, and most currently functioning power-stations - mainly second-generation installations - are theoretically nearing the end of their useful lives, at least in terms of what was said when they were being built. The problem therefore arises of their dismantling and the clean-up of the sites on which they were built, a thorny question on which Pierre Bonnaure casts light in this article (prospects, strategies, financing, management of waste etc.). Unfortunately, it emerges that in France nothing has really been resolved, that public debate on the matter is decidedly limited and that investment (both financial investment and research) is not commensurate with the needs of a sector which is, after all, the source of three quarters of national electricity production.

    2010-01-01

    According to statistics drawn up in 2009 by the Syndicat des Energies Renouvelables (SER, France's professional association of bodies involved in renewable energies), 250 MW of generating capacity were added during the year. This brings France's total installed photovoltaic capacity up to 430 MW. France's photovoltaic market grew from the world's 12. largest in terms of market size to 7. The broad guidelines which followed on from the legislation that emerged from the 'Grenelle of the Environment' are influencing the ways in which the market is to grow over the next few years: largest by the end of 2009. This was due to growth that was sustained by high feed-in tariffs and a drop in the price of equipment. - a target of 1100 MW of photovoltaic installed capacity by 2012, reaching 5 400 MW by 2020; - confirmation that tariff incentives will remain in place until 2012 and creation of an additional tariff for photovoltaic installations in large-sized buildings, such as commercial premises and industrial warehouses. This tariff has been fixed at 0,45 EUR per kWh; however, adjustment measures were announced at the end of 2009 to reduce a speculative approach that could ultimately lead to an hardening of access conditions to the higher tariffs. - the issuing of an invitation to tender for the construction of a least one photovoltaic power plant per region in France by 2011, providing a total of 300 MW of power. 2009 was mainly marked by an increase in the number of medium- and high-power plants, together with the emergence of a number of new organizations in the photovoltaic sector. The market continues to be strongly influenced by the priorities given to the integration of photovoltaics into buildings. The effects of the incentive measures that have been in place since 2006 (feed-in tariffs and fiscal measures) are still being felt. They continue to stimulate investment - both from private individuals and manufacturing organizations. In

    The penultimate stage of the 2013 Tour de France, the Annecy-Semnoz time-trial, has already been won – by a CERN staff member!     In keeping with tradition, the organisers of the Tour de France organise another race, the Étape du Tour, which is open to the general public and follows the actual route of an official stage of the Tour proper. This year, the chosen venue was Annecy and its neighbouring mountain, Le Semnoz, which played host to 11,000 cycling enthusiasts from all parts. This penultimate stage of the 2013 Tour will be raced by the professionals on 20 July. The public race was won by Nicolas Roux, an experienced cyclist and member of CERN’s GS-IS Group, who devoured the 128-km course in just 4 hours and 15 minutes, nine seconds ahead of cycling champion Julien Absalon. “I just managed to overhaul Julien Absalon 500 m before the finishing line,” Nicolas recounts. “It was a fantastic race!” Come rain o...

  13. Commercial applications of food ionization in France

    Santos, Pierre-Louis

    1994-01-01

    Due to the long history of nuclear energy in France, French public is not frightened by nuclear applications in its everyday life. The first industrial initiative on food ionization dates back to 1956. In 1980, the Joint Expert Committee on Food Ionization concluded that food ionization up to a certain maximum dose presented neither toxicological nor nutritional hazard. This opened the new era for the industrial development. But in 1988, a draft directive to harmonize national legislations was issued by the Commission of European Communities. This stopped many industrial initiatives due to uncertainty. It is estimated that nearly 14,000 tons of various food items have been ionized in France in 1991. About 40% are spices, followed by dry fruit, vegetables, and deboned poultry meat. Most of the present applications are intended to eliminate microorganisms. In 1992, 8 industrial facilities were in operation, mostly using gamma sources. Local research associations were founded to promote food ionization. Food ionization development in the past 30 years has been rapid and important, but the future of this process depends on the European harmonization of legislations. (K.I.)

  14. The development of nuclear power in France

    Vendryes, G.

    1985-01-01

    The author of this contribution, who read a paper on the same subject on the evening he was appointed Honorary Member of the Kerntechnische Gesellschaft (KTG), has been continuously engaged in a wide variety of activities within the French Atomic Energy Commission, CEA, for the past 32 years and has been in charge of the French breeder program since the late fifties. His analysis of the nuclear power situation in France and his survey of problems and development goals therefore is not only based on expert knowledge, but also reflects the official French idea of the rank nuclear power in the French energy supply policy and in the French economy. It shows that the foreseeable pronounced slowdown, due to declining demand, in the expansion of the network of nuclear power plants - a slowdown at a high level of capacity - does not detract from the growing importance of nuclear power in France. The awareness exists that this program can be, and must be, continued in its subareas. The French Government is convinced that the nuclear option was the only possible choice and that having decided in favor of it will pay even more in the future than it does already. (orig.) [de

  15. The chemical industry of uranium in France

    International Nuclear Information System (INIS)

    Goldschmidt, B.

    1955-01-01

    The actual CEA program is concerned with the construction of two large graphite reactors, each of those containing at least one hundred tons of uranium metal with nuclear purity. The uranium for these two reactors will be regularly supplied by new resources discovered in France and Madagascar in the last five years. The working and treatment of such ore have led to the creation of an important french industry of which the general outline and principle are described. The operated ores have got different natures and concentration, individual characteristics are described for the main ores.The most high-grade ore are transported to a central plant in Bouchet near Paris; the low-grade ore are concentrated by physical methods or chemical processes of which principles and economy are studied with constancy. The acid processes are the only used until now, although the carbonated alkaline processes has been studied in France. The next following steps after the acid process until the obtention of uranium rich concentrate are described. The purification steps of uranium compounds to nuclear purity material are described as well as the steps to elaborate metal of which the purity grade will be specify. Finally, the economic aspects of uranium production difficulty will be considered in relation with technical progresses which we can expect to achieve in the future. (M.P.)

    2013-11-01

    After having recalled the definition and origin of shale gases, the different non conventional gases and their exploitation techniques (hydraulic fracturing and horizontal drilling) this report examines whether these gases are an opportunity for France. Some characteristics and data of the fossil and gas markets are presented and commented: world primary energy consumption, proved reserves of non conventional gases and their locations, European regions which may possess reserves of shale gases and coal-bed methane, origins of gas imports in France. The second part addresses shale gas deposits and their exploitation: discussion of the influence of the various rock parameters, evolution of production. The third part discusses the exploitation techniques and specific drilling tools. The issue of exploitation safety and security is addressed as well as the associated controversies: about the pollution of underground waters, about the fact that deep drillings result in pollution, about the risks associated with hydraulic fracturing and injections of chemical products, about the hold on ground and site degradation, about water consumption, about pollution due to gas pipeline leakage, about seismic risk, about noise drawbacks, about risks for health, about exploration and production authorization and license, and about air pollution and climate. The last part addresses the French situation and its future: status of the energy bill, recommendations made by a previous government, cancellation of authorizations, etc. Other information are provided in appendix about non conventional hydrocarbons, about shale gas exploitation in the USA, and about the Lacq gas

    1984-08-01

    Simultaneous with the effort on fast breeder reactors launched several years ago in France, equivalent investigations have been conducted on the fuel cycle, and in particular on reprocessing, which is an indispensable operation for this reactor. The Rapsodie experimental reactor was associated with the La Hague reprocessing plant AT1 (1 kg/day), which has reprocessed about one ton of fuel. The fuel from the Phenix demonstration reactor is reprocessed partly at the La Hague UP2 plant and partly at the Marcoule pilot facility, undergoing transformation to reprocess all the fuel (TOR project, 5 t/y). The fuel from the Creys Malville prototype power plant will be reprocessed in a specific plant, which is in the design stage. The preliminary project, named MAR 600 (50 t/y), will mobilize a growing share of the CEA's R and D resources, as the engineering needs of the UP3 ''light water'' plant begins to decline. Nearly 20 tonnes of heavy metals irradiated in fast breeder reactors have been processed in France, 17 of which came from Phenix. The plutonium recovered during this reprocessing allowed the power plant cycle to be closed. This power plant now contains approximately 140 fuel asemblies made up with recycled plutonium, that is, more than 75% of the fuel assemblies in the Phenix core

  18. Elemental Abundances and their Implications for the Chemical Enrichment of the Boötes I Ultrafaint Galaxy

    We present a double-blind analysis of high-dispersion spectra of seven red giant members of the Boötes I ultrafaint dwarf spheroidal galaxy, complemented with re-analysis of a similar spectrum of an eighth-member star. The stars cover [Fe/H] from -3.7 to -1.9 and include a CEMP-no star with [Fe/H] = -3.33. We conclude from our chemical abundance data that Boötes I has evolved as a self-enriching star-forming system, from essentially primordial initial abundances. This allows us uniquely to investigate the place of CEMP-no stars in a chemically evolving system, in addition to limiting the timescale of star formation. The elemental abundances are formally consistent with a halo-like distribution, with enhanced mean [α/Fe] and small scatter about the mean. This is in accord with the high-mass stellar initial mass function in this low-stellar-density, low-metallicity system being indistinguishable from the present-day solar neighborhood value. There is a non-significant hint of a decline in [α/Fe] with [Fe/H]; together with the low scatter, this requires low star formation rates, allowing time for supernova ejecta to be mixed over the large spatial scales of interest. One star has very high [Ti/Fe], but we do not confirm a previously published high value of [Mg/Fe] for another star. We discuss the existence of CEMP-no stars, and the absence of any stars with lower CEMP-no enhancements at higher [Fe/H], a situation that is consistent with knowledge of CEMP-no stars in the Galactic field. We show that this observation requires there be two enrichment paths at very low metallicities: CEMP-no and "carbon-normal."

    A high-quality disordered Nd3+:Ca3Gd2(BO3)4 (Nd3+:CGB) laser crystal was grown by the Czochralski method. The space group and effective segregation coefficient of Nd3+ were determined to be Pnma and 1.06, respectively. The thermal properties, including the average linear thermal expansion coefficient, thermal diffusivity, specific heat, and thermal conductivity were systematically measured for the first time. It was found that the thermal conductivity increases with increasing temperature, indicating glasslike behavior. The polarized spectral properties of the crystal were investigated, including the polarized absorption spectra, polarized fluorescence spectra, and fluorescence decay. The spectroscopic parameters of Nd3+ ions in Nd3+:CGB crystal have been obtained based on Judd-Ofelt theory. The anisotropy of the spectral properties for different polarized directions was discussed. Additionally, the continuous-wave (CW) laser performance at 1.06 μm was demonstrated for the first time. The maximum output power of 603 mW was achieved with corresponding optical conversion efficiency of 8.33% and slope efficiency of 9.95%.

    A potential green emitting NaSrBO3:Tb3+ (1-9 mol%) phosphor was synthesized by a citrate gel combustion method. X-ray diffraction patterns confirmed the monoclinic phase of the phosphor. The phosphor emitted intense green emission under near-UV and electron excitation due to the characteristic transitions 5D4→7F6(488 nm),5D4→7F5(544 nm),5D4→7F4(586 nm) and 5D4→7F3(622 nm) of Tb3+ ions. The optimal molar concentration of Tb3+ ions was found to be 6 mol%, after that concentration quenching occurred. The dipole-dipole interaction was found to be accountable for energy transfer between the Tb3+ ions. X-ray photoelectron spectroscopy was carried out to analyze the chemical states of the elements and suggest that terbium was mostly presented in the (+3) valance state in the phosphor. The approximated Commission Internationale de l‧Eclairage coordinates for the PL (0.31, 0.61) and CL (0.33, 0.57) were found to be very close to the well-known green emitting phosphor. The obtained results suggest that the studied phosphor could be an ultimate choice for green emission in display applications.

    We present an efficient way to search a host for ultraviolet (UV) phosphor from UV nonlinear optical (NLO) materials. With the guidance, Na 3 La 2 (BO 3 ) 3 (NLBO), as a promising NLO material with a broad transparency range and high damage threshold, was adopted as a host material for the first time. The lanthanide ions (Tb 3+ and Eu 3+ )-doped NLBO phosphors have been synthesized by solid-state reaction. Luminescent properties of the Ln-doped (Ln=Tb 3+ , Eu 3+ ) sodium lanthanum borate were investigated under UV ray excitation. The emission spectrum was employed to probe the local environments of Eu 3+ ions in NLBO crystal. For red phosphor, NLBO:Eu, the measured dominating emission peak was at 613 nm, which is attributed to 5 D - 7 F 2 transition of Eu 3+ . The luminescence indicates that the local symmetry of Eu 3+ in NLBO crystal lattice has no inversion center. Optimum Eu 3+ concentration of NLBO:Eu 3+ under UV excitation with 395 nm wavelength is about 30 mol%. The green phosphor, NLBO:Tb, showed bright green emission at 543 with 252 nm excited light. The measured concentration quenching curve demonstrated that the maximum concentration of Tb 3+ in NLBO was about 20%. The luminescence mechanism of Ln-doped NLBO (Tb 3+ and Eu 3+ ) was analyzed. The relative high quenching concentration was also discussed

    The crystals of 1 mol% Ce-doped LuLiF{sub 4} (Ce:LLF) grown by the micro-pulling down ({mu}-PD) method and 1 mol% Ce-doped LuScBO{sub 3} (Ce:LSBO) grown by the conventional Czochralski (Cz) method were examined for their scintillation properties. Ce:LLF and Ce:LSBO demonstrated {approx}80% transparency at wavelengths longer than 300 and 400 nm, respectively. When excited by {sup 241}Am {alpha}-ray to obtain radioactive luminescence spectra, Ce{sup 3+} 5d-4f emission peaks were detected at around 320 nm for Ce:LLF and at around 380 nm for Ce:LSBO. In Ce:LSBO, the host luminescence was also observed at 260 nm. By recording pulse height spectra under {gamma}-ray irradiation, the absolute light yield of Ce:LLF and Ce:LSBO was measured to be 3600{+-}400 and 4200{+-}400 ph/MeV, respectively. Decay time kinetics was also investigated using a pulse X-ray equipped streak camera system. The main component of Ce:LLF was {approx}320 ns and that of Ce:LSBO was {approx}31 ns. In addition, the light yield non-proportionality and energy resolution against the {gamma}-ray energy were evaluated.

    1985-01-01

    As for the various problems on energy, Japan and France have taken the similar strategy and development program. Both Japan and France lack mineral energy resources, but have the industrial technical ability to make up for this shortage by substitute resources and to limit the dependence on import. Similarly to France, Japan has attained 3 tons in terms of petroleum per 1000 dollars of gross national product, which is about a half of the rate of energy consumption in the U.S., and became one of the advanced countries saving energy most. The consumption of petroleum decreased by 23 % in Japan and 30 % in France from 1973 to 1983. Nuclear power increased to 20 % of the generated output in Japan and to 50 % of that in France. The dependence on imported energy decreased to 80 % in Japan and 60 % in France. The energy policy taken by France was to satisfy demand, to diversity supply sources, to reduce energy cost, and to strengthen stable supply. The total demond of primary energy in 1984 was 191.6 million tons in terms of petroleum. Nuclear power stations generated 182 billion kWh in 1984. The nuclear power program in France, nuclear power stations and nuclear fuel cycle are reported. (Kako, I.)

    Elsa Devienne

    2010-01-01

    Full Text Available This article challenges the current scholarship on the history of the death penalty and its abolition by adopting a transatlantic framework and debunking the popular contemporary conception of the “Barbaric Americans” against the “civilised” anti-death penalty French. The article focuses on the short period in the 1970s during which American executions were halted by the Supreme Court, while France was still putting prisoners to death in cases that were widely debated in public opinion. By observing the French media’s reactions to the two major decisions taken by the Supreme Court in the 1970s and their direct consequences, this essay analyzes not only the French gaze on American practices but also how these American decisions were manipulated by the journalists to stoke the French debate about abolition.

    1982-01-01

    Only minor changes were introduced in the French nuclear programme by the new government in 1981. The operating conditions of Rapsodie were very satisfactory up to January 1982. After a leak in the double primary jacket (nitrogen circuit) the reactor was shut down for investigations. Phenix is continuing to operate smoothly. Construction of Super Phenix (Creys Malville power plant) is proceeding normally though with some delay. The studies for the future (after Creys Malville) are following their way both for the Project 1500 (Super Phenix 2) and for the specific plants of the fuel cycle. Research and development are largely directed toward Super Phenix 1 needs and the prospects of Super Phenix 2. International cooperation remains very intensive. The financial resources devoted to the development of fast reactors are globally stable. Including fuel cycle and safety (but excluding the Phenix operation) about 1300 millions of francs will be devoted to fast reactors by the C.E.A. in 1982. (author)

    Raw materials crisis and environmental awareness have lead to the question of intensively dealing with the recycling of plastics. Although plastic wastes (residues) industrially occuring have been recycled for a long time, this is certainly not always the case in the subsequent stages. One must particularly give thought to the considerable quantities of agricultural and municipal wastes. Besides the problem of collecting the waste which can only be satisfactorily solved by separate collection or setting up sorting places, it is necessary for the recycling plastic wastes on a large scale to find or develop sellable products. The product for sale is limited by economical aspects and prejudices against recycled materials. The public have taken to a series of measures in France to simplify recycling plastic wastes. Private industry is also beginning to take interest in this new sources of raw materials.

It discusses its various impacts (extreme meteorological events, dramatic impacts on ecosystems with the possible disappearance of some vegetal and animal species, crisis regarding food resources, health risks, population migrations notably because of sea level rise), and briefly evokes these impacts in France. It outlines the need for adaptation and describes the different adaptation principles: reduction of vulnerability, and anticipation of changes and of their impacts. It comments how adaptation and mitigation are two complementary approaches. It presents the French State strategy with its national adaptation strategy, its national adaptation plan, the mandatory elaboration of regional schemes for climate, air and energy, and the action of local communities

    Full Text Available We study financial literacy in France using the PATER survey and following the Lusardi and Mitchell (2011c approach. We find that some subpopulations are less financially literate than others: women, young and old people as well as less-educated people are more likely to face difficulties when dealing with fundamental financial concepts such as risk diversification and inflation and interest compounding. We also find some differences in financial knowledge depending on the political opinion of the respondents. Finally we show that these differences in financial knowledge are correlated with differences in the propensity to plan: people who score higher on the financial literacy questions are more likely to be engaged in the preparation of a clearly defined financial plan.
