  4. Enabling Technologies for Ceramic Hot Section Components

    Energy Technology Data Exchange (ETDEWEB)

    2009-04-30

    Silicon-based ceramics are attractive materials for use in gas turbine engine hot sections due to their high temperature mechanical and physical properties as well as lower density than metals. The advantages of utilizing ceramic hot section components include weight reduction, and improved efficiency as well as enhanced power output and lower emissions as a result of reducing or eliminating cooling. Potential gas turbine ceramic components for industrial, commercial and/or military high temperature turbine applications include combustor liners, vanes, rotors, and shrouds. These components require materials that can withstand high temperatures and pressures for long duration under steam-rich environments. For Navy applications, ceramic hot section components have the potential to increase the operation range. The amount of weight reduced by utilizing a lighter gas turbine can be used to increase fuel storage capacity while a more efficient gas turbine consumes less fuel. Both improvements enable a longer operation range for Navy ships and aircraft. Ceramic hot section components will also be beneficial to the Navy's Growth Joint Strike Fighter (JSF) and VAATE (Versatile Affordable Advanced Turbine Engines) initiatives in terms of reduced weight, cooling air savings, and capability/cost index (CCI). For DOE applications, ceramic hot section components provide an avenue to achieve low emissions while improving efficiency. Combustors made of ceramic material can withstand higher wall temperatures and require less cooling air. Ability of the ceramics to withstand high temperatures enables novel combustor designs that have reduced NO{sub x}, smoke and CO levels. In the turbine section, ceramic vanes and blades do not require sophisticated cooling schemes currently used for metal components. The saved cooling air could be used to further improve efficiency and power output. The objectives of this contract were to develop technologies critical for ceramic hot section

    Full Text Available La propagation plastique des mythes au sein des civilisations humaines et au fil du temps inscrit leur puissance mémétique dans la conscience des hommes. Nous sommes pris dans le filet tissé par l’évolutionnisme et le créationnisme, deux récits qui présupposent, pour le premier une loi immanente, pour le second une loi transcendante. Ce dualisme là est opérant, il bipolarise comme tout ce qui relève d’une double nature. La pensée mythique s’y originerait dans la faculté exceptionnelle du langage humain à se découpler du réel et à se référer à des réalités de l’espace intérieur et non plus du monde extérieur. L’animal fabulateur qu’est l’être humain a toujours inventé des machines à produire des simulacres, les récits mythiques et les livres en sont. Or, ces technologies de l’illusion fonctionnent trop bien. Elles nous maintiennent dans la croyance que ce que nous appelons du nom de “Réel” serait dans les réalités extérieures. Davantage qu’une matrice sémantique, le corpus mythique doit être envisagé comme une grossesse : un état transitoire entre un moment passé de fécondation, et celui, encore à venir de l’accouchement. Et là où la mythanalyse pourrait se concevoir comme une navigation pour remonter à la source d’un fleuve, la prospective de la lecture s’offre elle comme la quête d’un détroit de Magellan vers un océan intérieur : deux approches complémentaires pour les animaux fabulateurs que nous sommes.

    The decree n 2007-534 of April 10., 2007 authorizes Electricite de France to create a nuclear installation of base called(mentioned) Flamanville-3 containing a nuclear reactor of type EPR and intended for the electricity production. This authorization joins within the framework of the law of program number 2005-781 of July 13. 2005 fixing the orientations of the energy policy whom the article 4 foresees that: ' the government watches to keep an important part of production of nuclear origin, even if in the future, it makes the electricity production on an increasing part of renewable energies; the government thus settles for objective to maintain the nuclear option opened to the horizon 2020, by having in 2015, an operational nuclear reactor of new generation, allowing to opt for the replacement of the current generation. It is thus in front of the cliffs of Cotentin that will be built the EPR whom the starting is foreseen in 2012. The site of Flamanville shelters already two reactors put in service 20 years ago. EPR type reactors should make the transition between the current technologies of nuclear fission and the following generation which would base itself on inexhaustible sources of energy, thanks to technologies which have not showed their ability yet (as the nuclear fusion and the project of the ITER reactor). The question of the public debate and the right for the information is notably approached because of the secret-defence classification of technical information bound to the nuclear safety what was the object of a debate.

    2013-10-31

    A new high fluidity zinc high pressure die casting alloy, termed the HF alloy, was developed during laboratory trials and proven in industrial production. The HF alloy permits castings to be achieved with section thicknesses of 0.3 mm or less. Technology transfer activities were conducted to develop usage of the HF high fluidity alloy. These included production of a brochure and a one-hour webinar on the HF alloy. The brochure was then sent to 1,184 product designers in the Interzinc database. There was excellent reception to this mailing, and from this initial contact 5 technology transfer seminars were conducted for 81 participants from 30 companies across a wide range of business sectors. Many of the successful applications to date involve high quality surface finishes. Design and manufacturing assistance was given for development of selected applications.

    Background: Erythromelanosis follicularis faciei et colli (EFFC) has always been reported as a rare disorder, and more data are needed to define its etiology and epidemiology. Objectives: To present a descriptive study of this disorder from Kashmir and present a review of literature on the same. Materials and Methods: A cross-sectional, descriptive study was conducted on 14 patients with clinical lesions suggestive of EFFC, presenting to our dermatology outpatient clinic between May 2013 and April 2015. After obtaining informed consent from all patients, the demographic and clinical data were collected and punch biopsies were taken which after being fixed in formalin were stained for hematoxylin and eosin. The study was approved by Institutional Review Board. Results: Age of the patients ranged from 12 to 35 years with a mean age of 24.8 years. Females outnumbered males in a ratio of 1.3:1. Family history was positive in one case, and one patient had unilateral presentation. The classical triad of erythema, pigmentation, and follicular papules were present in 100% patients. Telangiectasias were observed in 28.57% patients only. Classical sites described were involved in all the cases (100%). In addition, lesions were found to involve eyebrows (28.57%), forehead (28.57%), upper lips (14.28%), and pinna (21.42%). Keratosis pilaris was present in all patients (100%); most common sites affected were upper arms and thighs. Two (14.28%) had generalized distribution. Histopathology in all correlated well with clinical findings. Conclusion: EFFC has always been reported as a rare disorder, but we believe that it is not so. The reason could be either lack of awareness of the disease by the patient due to its generally asymptomatic nature or under-recognition by the physicians. Awareness about the disease on part of dermatologist and recognition of clinical presentation is important for correct diagnosis and to help find more effective therapeutic modalities. PMID:27293252

    Educative platforms are at the heart of the development of online education. They can not only be reduced to technological aspects. Underlying models impact teaching and learning from the preparing of lessons to the learning sessions. Research related to these platforms are numerous and their stakes are important. For these reasons, we launched a call to a special issue on "Designs and uses of educative platforms" An educative platform is a computer system designed to automate various functions relating to the organization of the course, to the management of their content, to the monitoring of learners and supervision of persons in charge of various formations (Office de la langue fran\\c{c}aise, 2005). So educative platforms are Learning Management Systems (LMS) which are specific to education contexts.

    2006-07-01

    This special section brings together much of what is currently at the forefront of ion cyclotron resonance frequency (ICRF) research. Which theories are people working on? Where is progress being made? What results are being obtained? The present Nuclear Fusion section on ICRF is not—and was explicitly meant not to be—an overview or review of ICRF systems, research achievements or theories. It is more a snapshot of the leading edge of the investigations. It is based, in part, on presentations to the 16th Topical Conference on RF Power in Plasmas, Park City, Utah, USA, April 2005. The forefront of ICRF research currently being actively pursued covers a wide range of topics: theoretical, experimental and technological. As can be expected, most of the papers in this section have direct relevance to ITER. Elements that will be important in ITER, and that are being addressed and developed in the papers, are the presence of fast particles with their influence on wave propagation and damping, the non-linear mechanisms in the edge—in particular close to the wave launcher—and steady-state aspects. Specific ITER components as well as RF scenarios are studied. Continued efforts to improve the analytical description of wave damping and absorption and the availability of gradually more powerful computers led to significant progress in incorporating the effect of particles with non-thermal velocity distributions—the presence of which has already become significant in present-day machines due to massive RF and/or NBI heating which forces the particles away from thermo-dynamical equilibrium (Brambilla et al, Jaeger et al). The exact role that RF-created and fusion-born fast particles will play is still a matter of lively debate. As shown in the papers by Choi et al and Pinsker et al, the presence of energetic particles is a significant factor in the wave absorption, even at high harmonics. Accounting for the actual magnetic topology allows the capture of RF induced

    2009-07-01

    This paper provides an overview of early changes in the sectoral innovation system for power generation technologies which have been triggered by the European Emission Trading Scheme (EU ETS). Based on a broad definition of the sector, our research analyses the impact of the EU ETS on the four building blocks 'knowledge and technologies', 'actors and networks', 'institutions' and 'demand' by combining two streams of literature, namely systems of innovation and environmental economics. Our analysis is based on 42 exploratory inter-views with German and European experts in the field of the EU ETS, the power sector and technological innovation. We find that the EU ETS mainly affects the rate and direction of the technological change of power generation technologies within the large-scale, coal-based power generation technological regime to which carbon capture technologies are added as a new technological trajectory. While this impact can be interpreted as defensive behaviour of incumbents, the observed changes should not be underestimated. We argue that the EU ETS' impact on corporate CO2 culture and routines may prepare the ground for the transition to a low carbon sectoral innovation system for power generation technologies. (orig.)

    The oldest operating reactors are more than 35 years old and are now facing major maintenance operations. The first replacement of a pressurizer took place in autumn 2005 at the St-Lucie plant (Usa) while steam generators have been currently replaced since 1983. Nuclear industry has to adapt to this new market by proposing innovative technological solutions in the reactor maintenance field. This document gathers the 9 papers presented at the conference. The main improvements concern repair works on internal components of PWR-type reactors, the replacement of major components of the primary coolant circuit and surface treatments to limit the propagation of damages. The first paper shows that adequate design and feedback experience are good assets to manage the ageing of a nuclear unit. Another paper shows that a new repair method of a relief valve can avoid its replacement. (A.C.)

Data analysis shows the multiplicity of ways that teachers use to adjust their teaching. It stresses out the importance of science and technology teachers’ professionalism and suggests taking into account the complexity of teacher and student needs in the equation of teaching adjustment. Those needs call for an increased compatibility between teaching approaches and students’ needs. The adjustment of teaching approaches is also related to the quest for recognition, the teacher relationship with knowledge and the collective values in place

    Full Text Available L’approche psychanalytique des technologies de l’information et de la communication a longtemps considéré celles-ci comme un objet magique, dans le champ de l’éducation ou de la remédiation, mettant en avant que l’ordinateur ou le cyberespace sont de véritables objets transitionnels. Or force est de constater qu’en dépit de ces propositions, les TIC sont loin d’être vécues, pour tous les enseignants et tous les élèves, comme tels. D’ailleurs penser l’ordinateur, même connecté au réseau Internet, comme un objet transitionnel par essence, constituerait à coup sûr une interprétation un peu rapide de la théorie de Winnicott. Ce texte sera l’occasion de réfléchir précisément sur ces situations où l’ordinateur s’installe dans une aire intermédiaire, en reprenant les propositions de Winnicott. Il s’agira donc de tenter de cerner, d’une part, à quelles conditions les technologies de l’information et de la communication, dans la sphère professionnelle, peuvent se prêter au jeu et, d’autre part, comment les enseignants peuvent être en capacité de jouer avec ces technologies dans leurs pratiques professionnelles.In psychoanalytical oriented approach, information and communication technologies have been considered, for a long time in the field of the education, as a magical object. Researchers often advance that computer and cyberspace are transitional objects. But, in spite of these propositions, we have to admit that ICT are far from being lived as transitional, by all the teachers and all the pupils. Moreover to think the computer, even connected to the Internet network, as a transitional object by definition, would certainly constitute a too fast reading of the Winnicott’s theory. This text will give the opportunity to rethink about these situations where the computer really takes place in a transitional space. The aim of this paper is to show, on one hand, on which conditions the ITC, in the

    The propionaldehyde infrared regional integrated area reported by Köroğlu et al. were re-examined. Even though the spectrum seems to be recorded correctly, the comparison between their values with the data obtained by the integration of the propionaldehyde spectrum available in the PNNL database suggests that a scaling factor of 2.3025 (the ratio between ln and log bases) is the reason for their results being lower than those expected based on other literature values and quantum chemical estimates. Revised values were then reported for the four spectral regions evaluated by these authors, resulting in a much better agreement between both theoretical and experimental results for not only for this molecule but also for others like acetone and acetaldehyde.

  9. Reduction of Driver Stress Using AmI Technology while Driving in Motorway Merging Sections

    Zia, Kashif; Riener, Andreas; Ferscha, Alois

    High average intensity of traffic and problems like traffic congestions, road safety, etc. are challenging problems striking highway operators in these days. With the broad application of intelligent transport systems (ITS), particularly for the most dense street sections, some of these problems can be minimized or even solved; supplementary great potential is attributed to applications based on state-of-the art technology like car-to-x communication, for instance by extending an individuals "field of vision" by observations taken from all the vehicles in front. In this work we present a simulation based approach for improving driving experience and increasing road safety in merging sections by redirecting vehicles in advance according to a negotiation of requirements and desires of the flowing traffic on the main road and cars merging from the entrance lane. The simulation experiments performed in a cellular automaton based environment were data driven and on real scale, using traffic flow data on a minute-by-minute basis from a large urban motorway in a main city of the European Union. Our results have shown that the application of AmI technology has potential to influence driver's behavior (seamlessly invoking for a lane change well before an abrupt merging point) resulting in a reduction of panic, particularly for sections with limited range of view.

    The polyolefin industry is increasingly confronted with the challenge to meet restricting environmental regulations. In parallel, the environmentally conscious public opinion (customer), now globally organized, demands even more stringent anticipative actions to prevent any short or long term damages inflicted upon environment. The gradual shift from high pressure high temperature radical polymerisation for production of polyethylene to silica supported CrO{sub 3} based Phillips catalysts and several generations of stepwise improved TiCl{sub 3} based Ziegler-Natta catalyst technology has led to highly efficient catalytic systems accomplishing substantial improvement with respect to environmental issues. The development and progress of the last decade in single-site metallocene catalyst technology finally indicate that the advancing polyolefin industry has moved, in anticipation, towards even more modern technologies meeting the ultimate goal of employing clean processes that provide environmentally green products.

Conçue pour rétablir l’autorité historique de la France sur les arts décoratifs et la vénerie, une technique de chasse à courre traditionnelle, l’enclave française avait pour particularité de présenter ses trophées et artefacts cynégétiques au milieu de pièces de mobilier, de peintures et de tapisseries datant des XVIIe, XVIIIe et XIXe siècles. Si l’un des objectifs avoués du comité français était de promouvoir le tourisme de chasse dans ses colonies, il chercha également en Allemagne à restaurer ce qui était perçu comme une grandeur nationale en  décadence. En examinant l’accrochage de l’“Internationale Jagdausstellung” ainsi que les écrits de Guillaume Janneau, le commissaire des oeuvres d’art françaises, nous analysons comment la muséographie de la section française créait le récit d’une modernité culturelle nationaliste ancrée dans une vision réactionnaire du XVIIIe siècle, imaginé et mis en scène comme l’âge d’or de la pureté nationale.

    The Fission Energy and Systems Safety Program (FESSP) at LLNL was funded by the DOE Office of Safeguards and Security to develop an integrated system, hereafter referred to as the Security Clearance Electronic Processing, Transfer, Evaluation, and Recordkeeping (SCEPTER) System, for the electronic collection and transfer of personnel security data between clearance offices at contractor sites and DOE field offices and the Office of Personnel Management(OPM). This system will use existing software and hardware technologies where feasible. The project will consist of three phases. The first phase will investigate user needs, determine the feasibility of using existing technologies, and define project requirements. The second phase will be a pilot project to develop the computer systems and procedures required to automate the security clearance work flow within DOE and between DOE and OPM. Once the pilot system is implemented and tested, the decision to extend the system throughout DOE can be made. This third phase, the extension to a full production system, will require the investment of considerable funds in equipment and in the development of both a computer system and management infrastructure to support its successful operation. This investment will be undertaken only after the pilot system is operational and evaluated.

    The National Cancer Institute’s Center to Reduce Cancer Health Disparities has created pilot training opportunities under the “Continuing Umbrella of Research Experiences” (CURE) program that focus on emerging technologies (ET). In this pilot project, an eighteen month cancer biology research internship was reinforced with: instruction in an emerging technology (proteomics), a transition from the undergraduate laboratory to a research setting, education in cancer health disparities, and community outreach activities. A major goal was to provide underrepresented undergraduates with hands-on research experiences that are rarely encountered at the undergraduate level, including mentoring, research presentations, and participation in local and national meetings. These opportunities provided education and career development for the undergraduates, and they have given each student the opportunity to transition from learning to sharing their knowledge and from being mentored to mentoring others. Here, we present the concepts, curriculum, infrastructure, and challenges for this training program along with evaluations by both the students and their mentors. PMID:22528637

  5. L'ethique de l'environnement comme dimension transversale de l'education en sciences et en technologies: Proposition d'un modele educationnel

    Chavez, Milagros

    Cette these presente la trajectoire et les resultats d'une recherche dont l'objectif global est de developper un modele educationnel integrant l'ethique de l'environnement comme dimension transversale de l'education en sciences et en technologies. Face au paradigme positiviste toujours dominant dans l'enseignement des sciences, il a semble utile d'ouvrir un espace de reflexion et de proposer, sous forme d'un modele formel, une orientation pedagogique qui soit plus en resonance avec quelques-unes des preoccupations fondamentales de notre epoque: en particulier celle qui concerne la relation de humain avec son environnement et plus specifiquement, le role de la science dans le faconnement d'une telle relation, par sa contribution a la transformation des conditions de vie, au point de compromettre les equilibres naturels. En fonction de cette problematique generale, les objectifs de la recherche sont les suivants: (1) definir les elements paradigmatiques, theoriques et axiologiques du modele educationnel a construire et (2) definir ses composantes strategiques. De caractere theorico-speculatif, cette recherche a adopte la demarche de l'anasynthese, en la situant dans la perspective critique de la recherche en education. Le cadre theorique de cette these s'est construit autour de quatre concepts pivots: modele educationnel, education en sciences et en technologies, transversalite educative et ethique de l'environnement. Ces concepts ont ete clarifies a partir d'un corpus textuel, puis, sur cette base, des choix theoriques ont ete faits, a partir desquels un prototype du modele a ete elabore. Ce prototype a ensuite ete soumis a une double validation (par des experts et par une mise a l'essai), dans le but d'y apporter des ameliorations et, a partir de la, de construire un modele optimal. Ce dernier comporte deux dimensions: theorico-axiologique et strategique. La premiere s'appuie sur une conception de l'education en sciences et en technologies comme appropriation d

    La réévaluation des technologies de la santé (RTS), ce domaine émergent des services de santé et des recherches stratégiques, favorise la prise en charge optimale des technologies pendant toute leur vie utile. La RTS, qui est une évaluation structurée et fondée sur des données probantes des effets cliniques, économiques, sociaux et éthiques des technologies en place, permet de faire une utilisation optimale de ces technologies, d'en prévoir le retrait progressif et de mieux rentabiliser celles qui sont utilisées dans le milieu de la santé. Elle soulève des préoccupations éthiques chez les cliniciens qui prodiguent des soins directs aux patients, particulièrement lorsqu'elle vise un retrait progressif. Le présent article porte sur les considérations éthiques applicables aux cliniciens et à la RTS, selon une approche de la prise de décision bioéthique axée sur les principes.

    The {pi}{sup +} P and {pi}{sup -} P total cross sections have been measured between 500 and 1700 MeV to eliminate discrepancies in the experimental data. These new values have permitted a more precise calculation of the forward dispersion relation. These relations are well satisfied by the experimental data up to 18 GeV for charge exchange scattering. The dispersion relation for the spin-flip amplitude gives an efficient test for the phase-shift analysis solutions. (author) [French] Les sections efficaces totales {pi}{sup +} P et {pi}{sup -} P ont ete mesurees entre 500 et 1700 MeV pour eliminer les divergences qui existaient entre les resultats experimentaux anterieurs. Ces nouvelles valeurs ont permis de preciser le calcul des relations de dispersion vers l'avant. Dans le cas de la diffusion avec echange de charge ces relations sont en bon accord avec les resultats experimentaux entre 0 et 18 GeV. L'application des relations de dispersion vers l'avant a l'amplitude de spin-flip fournit une methode tres sensible pour comparer differentes series de dephasages en fonction de l'energie. (auteur)

    Obstetric surgical site infections (SSIs) are common and expensive to the health care system but remain under reported given shorter postoperative hospital stays and suboptimal post-discharge surveillance systems. SSIs, for the purpose of this paper, are defined according to the Center for Disease Control and Prevention (1999) as infection incurring within 30 days of the operative procedure (in this case, Caesarean section [CS]). Demonstrate the feasibility of real-life use of a patient driven SSIs post-discharge surveillance system consisting of an online database and mobile phone technology (surgical mobile app - how2trak) among women undergoing CS in a Canadian urban centre. Estimate the rate of SSIs and associated predisposing factors. Prospective cohort of consecutive women delivering by CS at one urban Canadian hospital. Using surgical mobile app-how2trak-predetermined demographics, comorbidities, procedure characteristics, and self-reported symptoms and signs of infection were collected and linked to patients' incision self-portraits (photos) on postpartum days 3, 7, 10, and 30. A total of 105 patients were enrolled over a 5-month period. Mean age was 31 years, 13% were diabetic, and most were at low risk of surgical complications. Forty-six percent of surgeries were emergency CSs, and 104/105 received antibiotic prophylaxis. Forty-five percent of patients (47/105) submitted at least one photo, and among those, one surgical site infection was detected by photo appearance and self-reported symptoms by postpartum day 10. The majority of patients whom uploaded photos did so multiple times and 43% of them submitted photos up to day 30. Patients with either a diagnosis of diabetes or self-reported Asian ethnicity were less likely to submit photos. Post-discharge surveillance for CS-related SSIs using surgical mobile app how2trak is feasible and deserves further study in the post-discharge setting. Copyright © 2017. Published by Elsevier Inc.

    Rapid diffusion, low cost and broad availability of information and communication technologies (ICTs) make them an attractive platform for managing care, communication and interventions in asthma. There is little information in Latin America about usage frequency of ICTs in asthmatic patients. The analysis undertaken consisted of an observational, cross-sectional study that aimed to identify the frequency and type of ICTs most often used by asthmatics. The Spanish version of the Michigan questionnaire was employed in five Latin American countries. Age and educational level was categorised. Logistic regression was performed among these groups concerning the frequency of ICT usage and the level of interest shown in seeking and receiving information about asthma. In total, 673 asthma patients were surveyed. The mean age was 43.44 years. Over two-thirds of the participants were female (68.4%). The most used ICT was the short message service (SMS) (69.9%). SMS and E-mail are useful tools for communicating (i.e. receiving and seeking information) with all asthma patients, irrespective of their age. WhatsApp (61.5%) and Facebook (32.0%) were rated as being the most interesting channels of communication for receiving information. Regression analysis showed that younger asthmatics and asthmatics with higher educational levels were most likely to use almost all forms of ICTs. ICTs are generally an attractive platform for managing care, communication and interventions to improve asthma care. SMS and E-mail were found to be the preferred ICT forms among users. However, social media forms such as WhatsApp and Facebook may also be appropriate for certain types of patient.

    Industrial technology already tested in Norway, North America and Algeria, the CO{sub 2} capture and sequestration (CCS) consists in collecting carbon dioxide and to inject it into deep geological traps. This solution, which contributes to the fight against climatic change, arouses a growing up interest in France as a consequence of the Grenelle Environnement meetings. At a time when big research and demonstration programs are launched everywhere in Europe, this book proposes for the first time a status of the knowledge gathered so far by the specialists of the IPG (World Physics Institute), of the BRGM (Bureau of Geologic and Mining Researches), of the IFP (French Petroleum Institute), and of the CNRS (National Center of Scientific Research). It takes stock of the stakes of this new technology in France. Beyond the technical discussions between experts, the book deals with the external communication stakes and the open public debates. The point of views of the different intervening parties (research organizations, environmental non-governmental organizations, European lobby (Zero Emission Platform), citizens, journalists and companies are compared. A large part of the book aims at shading light on the social acceptability question of this technology. In addition to a synthesis of the available literature, it presents and analyses two participation instruments: a dialogue workshop and a geographical information web site. Content: 1 - scientific stakes of CO{sub 2} geologic sequestration; 2 - technical stakes; 3 - economical stakes; 4 - risks and public opinion; 5 - social acceptability and territorial planning, the wind energy experience; 6 - the point of view of Action-Climat-France network (RAC-F); 7 - citizens' recommendations; 8 - the comeback of coal on the international energy scene; 9 - some consensus from a 'dialogue workshop': the social acceptability of CCS; 10 - bibliographic synthesis about the social acceptability of CCS; 11 - METSTOR

    Full Text Available China is the largest user of chemical-based conformance control treatments and a series of technologies have been successfully developed and deployed in recent years. This paper first shows the milestones of development and application of conformance control technologies in China. Then integrated conformance control technologies are reviewed followed by the lessons we have learned, and then a few major specific conformance control technologies are addressed, including tracer injection and channels explanation, potentiometric testing to identify areal sweep efficiency, Pressure Index (PI decisionmaking technology to select well candidate, complementary decision-making technology to select well candidate and design application parameters, and major chemicals for in-depth fluid diversion technologies. In addition, this paper also describes the principles and applications of some promising technologies of combined chemical-based conformance treatment with other EOR/IOR process, including the combination technology of surfactant and water shutoff, profile control and mini-scale surfactant flooding, acid treatment and profile control treatment. Finally, this paper summarizes the problems and challenges faced by mature water flooded oilfields in China. Based on recent well tests, tracer testing and interpretation, and previous water control treatment experience, it appears that channels or high permeability streaks are common in mature water flooded oilfields. Some research directions and promising technologies are suggested. La Chine est le plus grand utilisateur de méthodes chimiques pour l’amélioration du profil de balayage de l’eau pour l’exploitation des champs pétroliers matures. Toute une série de technologies y ont d’ailleurs été créées et déployées avec succès ces dernières années.

    Gai, Moshe

    2015-01-01

    We address a conflicting report on the value and uncertainty of the astrophysical cross section factor of the 12C(a,g) reaction extracted from existing data. In sharp contrast to previously reported ambiguities (by up to a factor 8), Schuermann et al. suggest an accuracy of 12%. We demonstrate that the so claimed "rigorous data selection criteria" used by Schuermann et al. relies on the s-factors extracted by Assuncao et al. But these results were shown in a later analysis (by this author) to have large error bars (considerably larger than claimed by Assuncao em et al.) which render these data not appropriate for a rigorous analysis. When their "rigorous data selection" is adjusted to remove the results of Assuncao et al. the astrophysical cross section factor cannot be extracted with 12% accuracy, or even close to it. Such data on the S_E2 values at low energies deviate by up to a factor two from their fit and exhibit a sharper slope rising toward low energies, leading to strong doubt on their extrapolated S...

    This report contains the measurements and evaluation of production cross sections of some medically and technologically important radionuclides over the energy range 1-40 MeV by using a conventional stacked-foil activation technique combined with high purity germanium (HPGe) -ray spectrometry. The irradiations were done by using the external beam line of the MC-50 cyclotron at the Korea Institute of Radiological and Medical Sciences (KIRAMS). The standard cross sections for monitor reactions were taken from IAEA web site. Integral yields for the investigated radionuclides were deduced using the measured cross-sections. Reported data were compared with the available literature data, theoretical calculations by the codes TALYS and ALICE-IPPE, and a good overall agreement among them was found.

    The importance of the capture cross section of the major fertile nuclei, /sup 238/U and /sup 232/Th, leads to the consideration of these data. The /sup 238/U (n,..gamma..) cross section is considered of priority as it is part of the /sup 238/U-/sup 239/Pu cycle. Experimental techniques used in the measurements of these data are considered. Data measured more recently are compared with provisions made for the possible explanations of differing results. It is concluded that the /sup 238/U (n,..gamma..) cross section is known with approx. 5% above 10 keV and fulfills the uncertainty limit for this cross section set to achieve design accuracy for k/sub eff/ and the breeding ratio above 500 keV. Below 500 keV, the present uncertainty falls short of the required 1.5 to 3.0% uncertainty. Specific recommendations are made to resolve existing discrepancies and data uncertainties. 84 references.

    Most of the experimental work on the interaction of neutrons with matter has focused on materials important to reactor physics and reactor structures. By comparison, the corresponding data for minor actinides or long-lived fission products are poor. A significant demand has developed for improved neutron cross-section data of these little-studied nuclides due to the surge of interest in the transmutation of nuclear waste. With 400 kg of {sup 129}I produced yearly in the reactors of the EU countries and a very long {beta}{sup -} half-life of 1.57 x 10{sup 7} years, iodine requires disposal strategies that will isolate this isotope from the environment for long periods of time. Therefore, {sup 129}I is potentially a key long-lived fission product for transmutation applications, since {sup 129}I transmutes in {sup 130}I after a single neutron capture and decays to {sup 130}Xe with a 12.36 h half-life. Accurate capture cross sections would help to reduce uncertainties in waste management concepts. For that purpose, Time-Of-Flight measurements covering the [0.5 eV-100 keV] energy range have been carried out at the 150 MeV pulsed neutron source GELINA of the Institute for Reference Materials and Measurements (IRMM). Two types of experiments have been performed at the IRMM, namely capture and transmission experiments. They are respectively related to the neutron capture and total cross sections. Since the PbI{sub 2} samples used in this work contain natural and radioactive iodine, extensive measurements of {sup 129}I have been carried out under the same experimental conditions as for the {sup 129}I. The data reduction process was performed with the AGS system, and the resonance parameters were extracted with the SAMMY and REFIT shape analysis codes. In a last step, the parameters have been converted into ENDF-6 format and processed with the NJOY code to produce point-wise and multigroup cross sections, as well as MCNP and ERANOS libraries.

    Conclusion We have shown that there has been a considerable increase in the rate of use of ICT in general practice in recent years, but these rates have fallen behind targets set by the NHS IT Strategy. Numerous barriers to the implementation of ICT exist, and further research is needed into means of overcoming them and on the evaluation of computer- supported consultations and other technologies in primary care.

    2014-11-01

    This article is based on the strategic reflection and discussion that took place on occasion of the first conference on innovation and technology transfer in the health sciences organized by the REGIC-ENS-FENIN-SEMICYUC and held in Madrid in the Instituto de Salud Carlos III on May 7th, 2013, with the aim of promoting the transfer of technological innovation in medicine and health care beyond the European program "Horizon 2020". The presentations dealt with key issues such as evaluation of the use of new technologies, the need to impregnate the decisions related to adoption and innovation with the concepts of value and sustainability, and the implication of knowledge networks in the need to strengthen their influence upon the creation of a "culture of innovation" among health professionals. But above all, emphasis was placed on the latent innovation potential of hospitals, and the fact that these, being the large companies that they are, should seriously consider that much of their future sustainability may depend on proper management of their ability to generate innovation, which is not only the generation of ideas but also their transformation into products or processes that create value and economic returns.

    2011-01-01

    Despite a body of literature focusing on the functionality of modern and stylistically distinct projectile points, comparatively little attention has been paid to quantifying the functionality of the early stages of projectile use. Previous work identified a simple ballistics measure, the Tip Cross-Sectional Area, as a way of determining if a given class of stone points could have served as effective projectile armatures. Here we use this in combination with an alternate measure, the Tip Cross-Sectional Perimeter, a more accurate proxy of the force needed to penetrate a target to a lethal depth. The current study discusses this measure and uses it to analyze a collection of measurements from African Middle Stone Age pointed stone artifacts. Several point types that were rejected in previous studies are statistically indistinguishable from ethnographic projectile points using this new measure. The ramifications of this finding for a Middle Stone Age origin of complex projectile technology is discussed.

    Full Text Available Abstract Background Many physicians are transitioning from paper to electronic formats for billing, scheduling, medical charts, communications, etc. The primary objective of this research was to identify the relationship (if any between the software selection process and the office staff's perceptions of the software's impact on practice activities. Methods A telephone survey was conducted with office representatives of 407 physician practices in Oregon who had purchased information technology. The respondents, usually office managers, answered scripted questions about their selection process and their perceptions of the software after implementation. Results Multiple logistic regression revealed that software type, selection steps, and certain factors influencing the purchase were related to whether the respondents felt the software improved the scheduling and financial analysis practice activities. Specifically, practices that selected electronic medical record or practice management software, that made software comparisons, or that considered prior user testimony as important were more likely to have perceived improvements in the scheduling process than were other practices. Practices that considered value important, that did not consider compatibility important, that selected managed care software, that spent less than $10,000, or that provided learning time (most dramatic increase in odds ratio, 8.2 during implementation were more likely to perceive that the software had improved the financial analysis process than were other practices. Conclusion Perhaps one of the most important predictors of improvement was providing learning time during implementation, particularly when the software involves several practice activities. Despite this importance, less than half of the practices reported performing this step.

    Full Text Available La lutte pour l’égalité entre les hommes et les femmes s’est manifestée dans tous les espaces sociaux, dont ceux de l’éducation et de l’emploi. Dans cette lutte, une stratégie déployée par le mouvement féministe et par les pouvoirs publics de nombreux pays fut de favoriser la présence des femmes dans les emplois dits non traditionnels. Malgré les luttes sociales et les interventions publiques visant à ouvrir l’horizon professionnel des femmes, il reste que les ghettos d’emplois sont encore fort présents. Notre objectif est de mieux comprendre le maintien de ces ghettos en abordant la question par un angle particulier : celui de l’orientation professionnelle d’étudiantes dans l’enseignement postsecondaire. Notre analyse s’appuie sur les parcours d’étudiantes qui, à un moment ou un autre de leur scolarité, ont envisagé de s’orienter vers des métiers ou des professions non-traditionnels. L’analyse dégage un premier constat, soit le faible nombre de filles qui envisagent poursuivre des études dans des domaines non traditionnels avant l’entrée dans l’enseignement postsecondaire (dans des programmes techniques ou scientifiques. Un second est le poids de l’expérience scolaire qui conduit de nombreuses filles à revoir leur orientation, notamment en reprenant des chemins plus traditionnels. A cet égard, il faut constater que l’expérience scolaire joue souvent comme un élément de désillusion professionnelle, qui devient une source de redéfinition des projets professionnels.The struggle for equality between men and women has appeared in every social field, including those of education and work. In this struggle, one of the strategies adopted by the feminist movement and by the governments of many countries has been to foster the participation of women in so-called non-traditional occupations.

    Every two years, the International Energy Agency (IEA) publishes the 'Energy Technology Perspectives' (ETP) report which analyses the foreseeable energy scenarios and strategies at the 2050 vista and stresses on the best available technologies. For the first time, the IEA describes in this study a scenario allowing to divide by two the CO{sub 2} emissions at the world scale, i.e. compatible with the 'factor 4' scenario of industrialized countries. The study estimates the R and D needs and the necessary additional investments to meet the different tendentious and voluntaristic scenarios proposed by the IEA. This 15. session of the cycle of energy-climate conferences aimed at presenting, from the ETP 2008 study, a thorough examination of the present day situation and perspectives of existing or future 'clean' energy technologies through the analysis of several scenarios. An examination of the interpretation of these scenarios at the France and European levels is made in order to define what should be the trends of public policies and international cooperation. This document gathers the transparencies of the two presentations given during this conference. The first presentation by Pieter Boot, Director of the Office of Sustainable Energy Policy and Technology of IEA, makes a synthesis of the ETP study and presents the recommendations of the agency. The second presentation by Olivier Appert, President of the French institute of petroleum (IFP), gives a counterpoint of the first presentation by considering the financing and acceptance aspects, in particular from the French point of view. Finally a debate with the audience completes the presentations. (J.S.)

    The ENDF/B-VII.1 library is our latest recommended evaluated nuclear data file for use in nuclear science and technology applications, and incorporates advances made in the five years since the release of ENDF/B-VII.0. These advances focus on neutron cross sections, covariances, fission product yields and decay data, and represent work by the US Cross Section Evaluation Working Group (CSEWG) in nuclear data evaluation that utilizes developments in nuclear theory, modeling, simulation, and experiment. The principal advances in the new library are: (1) An increase in the breadth of neutron reaction cross section coverage, extending from 393 nuclides to 418 nuclides; (2) Covariance uncertainty data for 185 of the most important nuclides, as documented in companion papers in this edition; (3) R-matrix analyses of neutron reactions on light nuclei, including isotopes of He, Li, and Be; (4) Resonance parameter analyses at lower energies and statistical high energy reactions at higher energies for isotopes of F, Cl, K, Ti, V, Mn, Cr, Ni, Zr and W; (5) Modifications to thermal neutron reactions on fission products (isotopes of Mo, Tc, Rh, Ag, Cs, Nd, Sm, Eu) and neutron absorber materials (Cd, Gd); (6) Improved minor actinide evaluations for isotopes of U, Np, Pu, and Am (we are not making changes to the major actinides 235,238U and 239Pu at this point, except for delayed neutron data, and instead we intend to update them after a further period of research in experiment and theory), and our adoption of JENDL-4.0 evaluations for isotopes of Cm, Bk, Cf, Es, Fm, and some other minor actinides; (7) Fission energy release evaluations; (8) Fission product yield advances for fission-spectrum neutrons and 14 MeV neutrons incident on 239Pu; and (9) A new Decay Data sublibrary. Integral validation testing of the ENDF/B-VII.1 library is provided for a variety of quantities: For nuclear criticality, the VII.1 library maintains the generally-good performance seen for VII.0 for a wide

    The Large Hadron Collider (LHC) at CERN in Geneva will soon deliver collisions with an energy never reached in a particle accelerator. An energy in the center of mass of 10 and ultimately 14 TeV will allow to go beyond the borders of the physics known so far. ATLAS, the largest detector ever built, will hunt the Higgs boson and search for new physics beyond the Standard Model. Any physical process is described by a cross section that measures its probability to occur. The events resulting from a given process are registered by ATLAS. To de- termine their according cross section, one has to know the luminosity. For the ATLAS experiment, a relative measurement of the luminosity can be done using the response of several sub-detectors. However to calibrate these detectors, an absolute measurement has to be performed. The ALFA detector has been designed to measure the elastic scattering spectrum that will allow to determine the absolute luminosity and the proton-proton total cross section. This provides an accurat...

    The ENDF/B-VII.1 library is our latest recommended evaluated nuclear data file for use in nuclear science and technology applications, and incorporates advances made in the five years since the release of ENDF/B-VII.0. These advances focus on neutron cross sections, covariances, fission product yields and decay data, and represent work by the US Cross Section Evaluation Working Group (CSEWG) in nuclear data evaluation that utilizes developments in nuclear theory, modeling, simulation, and experiment. The principal advances in the new library are: (1) An increase in the breadth of neutron reaction cross section coverage, extending from 393 nuclides to 423 nuclides; (2) Covariance uncertainty data for 190 of the most important nuclides, as documented in companion papers in this edition; (3) R-matrix analyses of neutron reactions on light nuclei, including isotopes of He, Li, and Be; (4) Resonance parameter analyses at lower energies and statistical high energy reactions for isotopes of Cl, K, Ti, V, Mn, Cr, Ni, Zr and W; (5) Modifications to thermal neutron reactions on fission products (isotopes of Mo, Tc, Rh, Ag, Cs, Nd, Sm, Eu) and neutron absorber materials (Cd, Gd); (6) Improved minor actinide evaluations for isotopes of U, Np, Pu, and Am (we are not making changes to the major actinides {sup 235,238}U and {sup 239}Pu at this point, except for delayed neutron data and covariances, and instead we intend to update them after a further period of research in experiment and theory), and our adoption of JENDL-4.0 evaluations for isotopes of Cm, Bk, Cf, Es, Fm, and some other minor actinides; (7) Fission energy release evaluations; (8) Fission product yield advances for fission-spectrum neutrons and 14 MeV neutrons incident on {sup 239}Pu; and (9) A new decay data sublibrary.

The compiled values are listed and plotted for reference without adjustments. From these collected results those values for which adequate supplementary information on nuclear constants, standards and experimental errors is provided are selected for use in reaction-by-reaction evaluations. These data are adjusted as needed to account for recent revisions in the nuclear constants and cross section standards. The adjusted results are subsequently transformed to equivalent cross sections at 14.7 MeV for the evaluation process. The evaluations are performed utilizing a least-squares method which considers correlations between the experimental data. 440 refs., 41 figs., 46 tabs.

    This paper describes how recent technological progresses should solve the difficulties encountered in the exploitation of natural gas fields in hard environments (far away or isolated fields, deep offshore, small or complex fields, production requiring a complex processing). These techniques concern: the exploration of fields and reservoirs, the deep-sea drilling and production (poly-phase pumping, hydrates formation control), the processing of crudes (water/oil and oil/gas separation, dehydration, de-acidification, removal of impurities), the transport (gas-pipelines, LNG and chemical conversion).

    This report summarizes the major activities conducted in the Chemical and Energy Research Section of the Chemical Technology Division at Oak Ridge National Laboratory (ORNL) during the period July-September 1999. The section conducts basic and applied research and development in chemical engineering, applied chemistry, and bioprocessing, with an emphasis on energy-driven technologies and advanced chemical separations for nuclear and waste applications. The report describes the various tasks performed within ten major areas of research: Hot Cell Operations, Process Chemistry, Molten Salt Reactor Experiment (MSRE) Remediation Studies, Chemistry Research, Physical Properties Research, Biochemical Engineering, Separations and Materials Synthesis, Fluid Structures and Properties, Biotechnology Research, and Molecular Studies. The name of a technical contact is included with each task described, and readers are encouraged to contact these individuals if they need additional information. Activities conducted within the area of the Cell Operations involved the testing of two continuously stirred tank reactors in series to evaluate the Savannah River-developed process of small-tank tetraphenylborate precipitation to remove cesium, strontium and transuranics from supernatant. Within the area of Process Chemistry, various topics related to solids formation in process solutions from caustic treatment of Hanford sludge were addressed. Saltcake dissolution efforts continued, including the development of a predictive algorithm. New initiatives for the section included modeling activities centered on detection of hydrogen in {sup 233}U storage wells and wax formation in petroleum mixtures, as well as support for the Spallation Neutron Source (investigation of transmutation products formed during operation). Other activities involved in situ grouting and evaluation of options for use (i.e., as castable shapes) of depleted uranium. In a continuation of activities of the preceding

    Let X be an algebraic curve, defined over a perfect field, and G a divisor on X. If X has sufficiently many points, we show how to construct a divisor D on X such that l(2D-G)=0, of essentially any degree such that this is compatible the Riemann-Roch theorem. We also generalize this construction to the case of a finite number of constraints, l(k_i.D-G_i)=0, where |k_i|\\leq 2. Such a result was previously claimed by Shparlinski-Tsfasman-Vladut, in relation with the Chudnovsky-Chudnovsky method for estimating the bilinear complexity of the multiplication in finite fields based on interpolation on curves; unfortunately, as noted by Cascudo et al., their proof was flawed. So our work fixes the proof of Shparlinski-Tsfasman-Vladut and shows that their estimate m_q\\leq 2(1+1/(A(q)-1)) holds, at least when A(q)\\geq 5. We also fix a statement of Ballet that suffers from the same problem, and then we point out a few other possible applications.

    The present work is based on the selection of e{sup -}e{sup +} {yields} f f-bar events taken with the ALEPH detector from 1995 to 1998, for an integrated luminosity of 500 pb{sup -}. We first present the selection of dimuon, di-tau and di-electron events that we have been developed for this study. The hadronic selection used in ALEPH is also detailed in a devoted part. In each case, the estimation of systematic uncertainties is described. They are of the same order of magnitude as the statistical errors, ranging between 0.6% (di-electron) and 3.5% (dimuon). From these selections we derive the di-fermionic cross-sections as well as the asymmetries computed for the di-lepton channels. Measurements are found to be in reasonable agreement with the Standard Model expectations. Cross-sections and asymmetries are sensitive to the presence of possible new physics. In this document we use the context of the 4-fermion contact interactions to set limits on the energy scale of new physics. Such limits are found to range between 7 and 15 GeV depending on the modelling used. We also put lower limits on the mass of leptoquarks, 590 GeV/c{sup 2} for vector leptoquarks and 71 GeV/c{sup 2} for scalar leptoquarks. Eventually we also present the limits derived in the context of R-parity violated supersymmetry, putting constraint on the s-neutrino mass. Our study excludes such particles below a few hundred GeV/c{sup 2} mass for high values of their Yukawa coupling assumptions.

    Recommendations for Heavy-Section Steel Technology Program's investigation into the influence of crack depth on the fracture toughness of a steel prototypic of those in a reactor pressure vessel are included in this report. The motivation for this investigation lies in the fact that probabilistic fracture mechanics evaluations show that shallow flaws play a dominant role in the likelihood of vessel failure, and shallow-flaw specimens have exhibited an elevated toughness compared with conventional deep-notch fracture toughness specimens. Accordingly, the actual margin of safety of vessels may be greater than that predicted using existing deep-notch fracture-toughness results. The primary goal of the shallow-crack project is to investigate the influence of crack depth on fracture toughness under conditions prototypic of a reactor vessel. A limited data base of fracture toughness values will be assembled using a beam specimen of prototypic reactor vessel material and with a depth of 100 mm (4 in.). This will permit comparison of fracture-toughness data from deep-cracked and shallow-crack specimens, and this will be done for several test temperatures. Fracture-toughness data will be expressed in terms of the stress-intensity factor and crack-tip-opening displacement. Results of this investigation are expected to improve the understanding of shallow-flaw behavior in pressure vessels, thereby providing more realistic information for application to the pressurized-thermal shock issues. 33 refs., 17 figs.

    The emerging field of Information and Communications Technology (ICT) has brought about new interaction styles. Its excessive use may lead to addictive behaviours. The objective is to determine the prevalence of the problematic use of ICT such as Internet, mobile phones and video games, among adolescents enrolled in mandatory Secondary Education (ESO in Spanish) and to examine associated factors. Cross sectional, multi-centric descriptive study. 5538 students enrolled in years one to four of ESO at 28 schools in the Vallès Occidental region (Barcelona, Spain). self-administered socio-demographic and ICT access questionnaire, and validated questionnaires on experiences related to the use of the Internet, mobile phones and video games (CERI, CERM, CERV). Questionnaires were collected from 5,538 adolescents between the ages of 12 and 20 (77.3 % of the total response), 48.6 % were females. Problematic use of the Internet was observed in 13.6 % of the surveyed individuals; problematic use of mobile phones in 2.4 % and problematic use in video games in 6.2 %. Problematic Internet use was associated with female students, tobacco consumption, a background of binge drinking, the use of cannabis or other drugs, poor academic performance, poor family relationships and an intensive use of the computer. Factors associated with the problematic use of mobile phones were the consumption of other drugs and an intensive use of these devices. Frequent problems with video game use have been associated with male students, the consumption of other drugs, poor academic performance, poor family relationships and an intensive use of these games. This study offers information on the prevalence of addictive behaviours of the Internet, mobile phones and video game use. The problematic use of these ICT devices has been related to the consumption of drugs, poor academic performance and poor family relationships. This intensive use may constitute a risk marker for ICT addiction.

    Tissue Microarray (TMA) is a widely used method to perform high-throughput immunohistochemical analyses on different tissues by arraying small sample cores from paraffin-fixed tissues into a single paraffin block. TMA-technology has been validated on numerous cancer tissues and also for gastric cancer studies, although it has not been validated for this tumor tissue so far. The objective of this study was to assess, whether the 2-mm TMA-technology is able to provide representative samples of gastric cancer tissue. TMA paraffin blocks were constructed by means of 220 formalin-fixed and paraffin-embedded gastric cancer samples with a sample diameter of 2 mm. The agreement of immunohistochemical stainings of Glut-1 and Hif-1 alpha in TMA sections and the original full sections was calculated using kappa statistics and direct adjustment. The congruence was substantial for Glut-1 (kappa 0.64) and Hif-1 alpha (kappa 0.70), but with an agreement of only 71% and 52% within the marker-positive cases of the full-section slides. Due to tumor heterogeneity primarily, the TMA technology with a 2-mm sample core shows relevant limitations in gastric cancer tissue. Although being helpful for tissue screening purposes, the 2-mm TMA technology cannot be recommended as a method equal to full-section investigations in gastric cancer.

    Full Text Available The purpose of the Technology and High School Success (THSS initiative was to encourage innovative strategies focused on improving provincial high school completion rates, using technology and student-centered learning to engage student interest. The primary purpose of this paper is to report on barriers that impede systemic, effective and sustainable technology integration within schools. Even with teacher and administrative support and commitment for THSS, evaluative research indicated minimal change in system capacity as a result of the initiative. Three primary barriers to program sustainability were: 1 schools and school districts did not leverage the opportunity to revisit their existing vision(s, 2 schools and school districts did not use data to make changes, and 3 limited access to technology. Le but de l’initiative « Technology and High School Success (THSS » était d'encourager des stratégies novatrices visant à améliorer le taux d’achèvement des études secondaires dans la province de l’Alberta en utilisant la technologie et un apprentissage centré sur l'élève afin de susciter l'intérêt des élèves. L'objectif principal de cet article est de rendre compte des obstacles entravant l'intégration systémique, efficace et durable de la technologie dans les écoles. La recherche évaluative a révélé des changements minimes dans la capacité systémique à la suite de l'initiative, et ce, malgré l’appui et l’engagement des enseignants et des administrateurs envers le THSS. Les trois obstacles principaux à la viabilité du programme sont les suivants: 1 les écoles et les districts scolaires n'ont pas profité de l’occasion pour revoir leur(s vision(s, 2 les écoles et les districts scolaires n'ont pas utilisé les données pour effectuer des changements, et 3 l'accès limité à la technologie.

    A collaborative study to compare the long-term measurement performance between guarded-hot-plate facilities at the Laboratoire national de métrologie et d’essais (LNE) in France and the National Institute of Standards and Technology (NIST) in the United States is presented. Thermal conductivity data were compiled from three international comparisons organized from 1997 to 2014. Measurements were conducted in accordance with standardized test methods (ISO 8302 or ASTM C 177) over a temperature range from 280 K to 320 K. Nine thermal insulating materials (either mineral fiber or expanded polystyrene) were examined covering broad ranges of bulk densities (13 kg · m-3-200 kg · m-3) and thicknesses (13 mm-70 mm). A different set of specimens was utilized for each comparison. Results of this study indicate that, over a 17 year interval, the majority of test data from LNE and NIST agreed to within  ±1.0%, or less, for mineral fiber materials and to within  ±0.5%, or less, for expanded polystyrene. The long-term variability limit of 1% between the two laboratories is in good agreement with their current measurement uncertainties. Regression coefficients and their standard uncertainties for a straight-line model relating thermal conductivity to temperature from 280 K to 320 K were computed by material and laboratory. Graphical analysis of the data and corresponding fits exhibit consistent behavior by material type between the two laboratories. Sources of measurement variability are addressed.

    赠卵体外受精-胚胎移植(IVF-ET)技术的发展为卵巢储备功能低下及卵巢功能衰竭的患者带来生育希望的同时也带来了许多新的伦理问题。解决和协调赠卵IVF-ET技术的发展与伦理原则之间的冲突是确保技术合理应用的前提。卵子供需失衡,赠卵者经济补偿额度设定,赠/受卵者条件,以及匿名双盲子代告知的制度是目前的热点伦理问题。针对上述问题系统的回顾文献,提出了相应的解决办法:增加配子捐赠途径同时发展卵子冷冻技术是目前解决卵子供需冲突的办法之一;赠卵补偿额度可根据地区发展水平以及卫生经济学研究结果决定;随着各中心妊娠率的提高可考虑适当放宽对捐赠者卵子个数的要求;赠卵IVF前对受卵者进行全面评估以保障受者和子代的利益;匿名双盲可于合适时机揭盲。%The development of in vitro fertilization-embryo transfer (IVF-ET) with oocyte donation technology brings new hope for infertility patients with ovarian failure, as well as some new ethic problems for the whole society. The conflicts between the development of new technology and ethical problems should be integrated in consideration, which is the precondition of the reasonable application of this new technology. The hot ethic issues at present include the supply-demand imbalance of oocyte, donor compensation, requirement for donor and recipient, anonymous and child informed. We reviewed the previous publications and proposed some suggestions for these problems: to match gradually the supply-demand imbalance by increasing donation and developing oocyte-frozen technology, to plan the compensation according to the economic development and health-economic study, to adjust properly the requirement for donor-oocytes since the pregnant rate was increasingly improved, to evaluate comprehensively the psychology and economic state of recipient before IVF, and to reconsider

    Full Text Available This position paper explores the ambiguity of technology, toward refined understanding of Educational Technology. The purpose of education is described by John Dewey as growing, or habitual learning. Two philosophical conceptions of technology are reviewed. Dewey positions inquiry as a technology that creates knowledge. Val Dusek offers a “consensus definition,” a systems approach to technology that merges into social construction theory and actor-network theory, both of which emphasize complex relations between humans and technology. Using Dewey and Dusek as reference, literature related to Educational Technology is reviewed. A history of its definitions and conceptions of hard (material technology and of soft (process technology are examined. Three brief case studies reveal a bias toward hard technology in contemporary discourse. A misconception that soft technology begins with pre-authenticated knowledge is identified and shown to obscure the reciprocity between technology and the intellect. Cet exposé de position se penche sur l’ambiguïté de la technologie en vue de raffiner la compréhension de la technologie pédagogique. L’objectif de l’éducation est décrit par John Dewey comme étant un apprentissage croissant ou habituel. Deux conceptions philosophiques de la technologie sont examinées. Dewey considère l’enquête comme une technologie qui crée le savoir. Val Dusek offre une « définition consensuelle », une approche systémique de la technologie qui rejoint la théorie de la construction sociale et la théorie de l’acteur-réseau, qui mettent toutes deux l’accent sur les relations complexes entre les humains et la technologie.

    In 2003-2004 the HERA collider delivered e{sup +}p collisions with a longitudinally polarised positron beam. We prescribe the measurement of inclusive Neutral and Charged Current DIS (deep inelastic scattering) cross section using the H1 detector. The total Charged Current cross section for Q{sup 2} > 400 GeV{sup 2}, y < 0,9 is measured with a Right-handed (P = 0,33) sample of 15,3 pb{sup -1} and a Left-handed (P = -0,40) sample of 21,7 pb{sup -1} yielding {sigma}cc (P = +0,33) = 34,67 pb {+-} 1,94 pb (stat) {+-} 1,66 pb (sys) C.20) {sigma}cc(P = -0,40) = 13,80 pb {+-} 1,04 pb (stat) {+-} 0,94 pb (sys). C.21) This result is consistent with the proportionality of the cross section with respect to the polarisation, in good agreement with the Standard Model expectations. The second part of this work is devoted to QCD analysis of the proton structure. The H1 data alone are used to extract flavor separated parton densities. This analysis is further used as a basis to extract various electroweak parameters, such as the W boson mass and the quarks couplings to the Z. Then a global QCD analysis of DIS and Drell Yan data is realized, focusing on the strange sea asymmetry which is found to be small: {integral}{sub 0}{sup 1} x(s - s-bar)dx = (1,8 {+-} 3,8) x 10{sup -4}. The impact of new E866 data on high x partons densities is discussed and the extraction of the strong coupling is realized {alpha}s = 0,1197 {+-} (+0,0005 - 0,0007)(mod) {+-}0,006 (th). (author)

    2016-12-01

    Full Text Available Earthen architectural fragments (burned or cemented are often collected during the excavation in Italian prehistoric and protohistoric sites. The technological characterization of these remains is relevant to recognize the existence of local or regional building traditions and to understand the exploitation of raw materials and, more in general, the ancient production strategies. In addition to the current macroscopic analysis (morphology of fragments and classification of pastes and before the realization of archaeometric analysis, it’s possible to complete the analytical protocol of daub with some observations in polished section. To realize a polished section, the daub sample is cut and the resulting section is polished with sandpaper. The realization of this kind of section allows a better description of the arrangement of the constituents, to identify the processes of transformation and deformation of raw materials during the building activity. The aim of these mesoscopic analysis is to characterize the behavioral chain referred to the processing of raw materials and their installation, linking the observed characteristics to specific actions. It’s possible to obtain some functional data about the original function of the earthen structures or the dynamics of entrance in the archaeological record a well. This paper presents some case-studies and some preliminary keys to understand the features observed in polished section. The use of this analytical technique gives some encouraging results, especially in comparing the number of relevant data to the low cost of production of a polished section.

    Full Text Available Abstract Background Knowledge about the relation between user involvement in the provision of assistive technology and outcomes of assistive technology use is a prerequisite for the development of efficient service delivery strategies. However, current knowledge is limited, particularly from low-income countries where affordability is an issue. The objective was therefore to explore the relation between outcomes of assistive technology use and user involvement in the service delivery process in Bangladesh. Methods Using structured interviews, data from 136 users of hearing aids and 149 users of manual wheelchairs were collected. Outcomes were measured using the International Outcome Inventory for Hearing Aids (IOI-HA, which was adapted for wheelchair users. Predictors of user involvement included preference, measurement and training. Results Users reported outcomes comparable to those found in other high- and low-income countries. User involvement increased the likelihood for reporting better outcomes except for measurement among hearing aid users. Conclusions The findings support the provision of assistive technology as a strategy to improve the participation of people with disabilities in society. They also support current policies and guidelines for user-involvement in the service delivery process. Simplified strategies for provision of hearing aids may be explored.

    It is well known, if not well explained, that photo cross-sections curves depend on numerical resolution; as well as many other physical solutions from integral equations of the first kind, they are oscillating. In the first part of this report, a typical example points out how oscillations are growing. In the second part, a new method is explained yielding a smooth resolution. From experimental data on equidistant intervals, we build functions expanded in Tchebycheff polynomials; the solution is of this kind. Then, the third part points out that semi-analytical resolutions of this problem are illusive. (author) [French] C'est un fait reconnu mais mal explique, que les courbes de sections efficaces photonucleaires dependent de la resolution numerique adoptee. Beaucoup d'autres solutions physiques extraites d'une equation integrale de 1ere espece sont dans ce cas; elles sont arbitraires et oscillatoires. Dans la 1ere partie de ce rapport, on montre, dans un cas particulier typique, comment se forment les oscillations. Dans la 2eme partie, on presente une methode originale qui permet d'obtenir une resolution exempte d'oscillations. A partir de donnees experimentales a intervalles equidistants, on construit des fonctions developpees en polynomes de Tchebycheff; la solution est de ce type. Enfin, on montre dans la 3eme partie que les resolutions semi-analytiques de ce probleme sont illusoires. (auteur)

    To summarize excellent current research in the field of Bioinformatics and Translational Informatics with application in the health domain and clinical care. We provide a synopsis of the articles selected for the IMIA Yearbook 2015, from which we attempt to derive a synthetic overview of current and future activities in the field. As last year, a first step of selection was performed by querying MEDLINE with a list of MeSH descriptors completed by a list of terms adapted to the section. Each section editor has evaluated separately the set of 1,594 articles and the evaluation results were merged for retaining 15 articles for peer-review. The selection and evaluation process of this Yearbook's section on Bioinformatics and Translational Informatics yielded four excellent articles regarding data management and genome medicine that are mainly tool-based papers. In the first article, the authors present PPISURV a tool for uncovering the role of specific genes in cancer survival outcome. The second article describes the classifier PredictSNP which combines six performing tools for predicting disease-related mutations. In the third article, by presenting a high-coverage map of the human proteome using high resolution mass spectrometry, the authors highlight the need for using mass spectrometry to complement genome annotation. The fourth article is also related to patient survival and decision support. The authors present datamining methods of large-scale datasets of past transplants. The objective is to identify chances of survival. The current research activities still attest the continuous convergence of Bioinformatics and Medical Informatics, with a focus this year on dedicated tools and methods to advance clinical care. Indeed, there is a need for powerful tools for managing and interpreting complex, large-scale genomic and biological datasets, but also a need for user-friendly tools developed for the clinicians in their daily practice.

    The French inter-ministry committee for clean vehicles (CIVP) published in 1999 a report about the status of development of the different clean vehicle technologies (electric-powered, LPG-fueled, natural gas fueled, hybrid, fuel cells) and accompanied by recommendations for public policies. A re-evaluation of these technologies was planned by the end of 2002 and is the purpose of this document. The first part makes a status of the actions carried out by the public authorities since the previous CIVP report. The second part presents the present day situation of the LPG, natural gas and electric technologies. It describes also the recent advances in the classical technologies (gasoline and diesel engines) and includes a part about battery technologies and about the use of bio-fuels. The status of each technology is presented both for France and for foreign countries and with its perspectives of evolution. (J.S.)

    Modern techniques of mandibular reconstruction, such as CAD-CAM technology and rapid prototyping, offer new means by which reconstructive surgery can be planned to optimise aesthetic outcomes and prosthetic rehabilitation. The high degree of accuracy afforded by these approaches is principally attributable to high-precision fibular sectioning and insertion of the bone into a customised bone plate. CAD-CAM mandibular reconstruction procedures using vascularised bone free-flap transfers were performed on 10 patients with benign or malignant neoplasms. Five were not treated with the aid of CAD-CAM technology, and served as the control group. Five were scheduled for maxillofacial surgery using surgical cutting guides and customised bone plates. A generalised linear model for linear measures was used to compare the accuracy of reconstruction between the two groups. A difference, even though not significant, in the lateral shift of the mesial and distal positions of the fibular units was evident between groups. CAD-CAM-generated fibular surgical guides afford improved accuracy when used to restore native anatomy, especially in the context of mandibular arch restoration, and both operating room time and related costs are reduced during fibular sectioning.

    Molten Salt Reactor (MSR) based on Th/U cycle is one of the new generation concepts for nuclear energy production. A typical MSR is a graphite-moderated core with liquid fuel ({sup 7}LiF +ThF{sub 4} + UF{sub 4}). Many numerical studies based on Monte-Carlo codes are currently carried out but the validity of these numerical result relies on the precise knowledge of neutron cross sections used such as elastic scattering on carbon ({sigma}{sub C}), fluorine ({sigma}{sub F}) and lithium 7 ({sigma}{sub Li}). The goal of this work is to obtain {sigma}{sub C} and {sigma}{sub F} between 1 eV and 100 keV. Such measurements have been performed at the Laboratoire de Physique Subatomique et de Cosmologie (LPSC) de Grenoble on the experimental platform PEREN using slowing-down time spectrometers (C and CF{sub 2}) associated to a pulsed neutron generator (GENEPI). Capture rates are obtained for reference materials (Au, Ag, Mo and In) using YAP scintillator coupled to a photo-multiplier. Very precise simulations (MCNP code) of the experimental setup have been performed and comparison with experiments has led to the determination of {sigma}{sub C} and {sigma}{sub F} with accuracies of 1% and 2% respectively. These results show a small discrepancy to evaluated nuclear data file (ENDF). Measures of total cross-sections {sigma}{sub C} and {sigma}{sub F} at higher energy (200 - 600 keV) were also carried out at Centre des Etudes Nucleaires de Bordeaux using a transmission method. Mono-energetic neutrons were produced by protons accelerated by a Van de Graaff accelerator on a LiF target and transmitted neutrons are counted in a proportional hydrogen gaseous detector. Discrepancies of 5% and 9% for {sigma}{sub C} and {sigma}{sub F} respectively with ENDF have been shown. (author)

    Full Text Available À partir d’une étude anthropologique des pratiques cliniques en milieux de soins tertiaires, cet article s’intéresse aux défis posés par les progrès médicaux et technologiques en unités de soins intensifs (aigus et en unités d’oncologie pédiatrique (chroniques. Ces progrès interpellent quotidiennement médecins et personnel infirmier, posant des défis pour lesquels peu de réponses existent. Normes et valeurs s’actualisent en ces lieux où des enjeux entourant la vie, la “qualité” de vie, et la mort sont quotidiens. L’hôpital pédiatrique est certes un endroit où tous les espoirs sont permis. C’est aussi un lieu où la mort est à apprivoiser ; elle devient un choix, s’imposant rarement d’elle-même. Sur la base des témoignages des soignants et de nos propres observations, nous proposons une réflexion sur la ‘fin de vie’, objet d’un choix difficile, en dialogue avec la technologie qui la rend possible. Ces différentes voix témoigneront de rationalités parfois parallèles, convergentes ou divergentes, et des normes et valeurs qui s’affrontent, se rencontrent et se négocient dans l’espace social de la clinique.Stemming from an anthropological study of clinical practices in tertiary health care institutions, our paper focuses on challenges brought by medical and technological progress in paediatric intensive care units (acute and oncology units (chronic. This progress affects clinicians and nurses daily, posing challenges for which there are no ‘easy’ solutions. Norms and values surface in these clinical settings where issues regarding life, quality of life and death are part of everyday practice. A paediatric hospital is certainly a place where all hopes are warranted, but it is also a place where death must be acknowledged. Death is in fact often a question of choice as it almost always avoidable. Through the testimonies of health care professionals and our own field observations, we offer a

    Purpose: Social media and mobile technology are transforming the way in which young physicians are learning and practicing medicine. The true impact of such technologies has yet to be evaluated. Methods and Materials: We performed a nationwide cross-sectional survey to better assess how young radiation oncologists used these technologies. An online survey was sent out between April 24, 2013, and June 1, 2013. All residents attending the 2013 radiation oncology French summer course were invited to complete the survey. Logistic regressions were performed to assess predictors of use of these tools in the hospital on various clinical endpoints. Results: In all, 131 of 140 (93.6%) French young radiation oncologists answered the survey. Of these individuals, 93% owned a smartphone and 32.8% owned a tablet. The majority (78.6%) of the residents owning a smartphone used it to work in their department. A total of 33.5% had more than 5 medical applications installed. Only 60.3% of the residents verified the validity of the apps that they used. In all, 82.9% of the residents had a social network account. Conclusions: Most of the residents in radiation oncology use their smartphone to work in their department for a wide variety of tasks. However, the residents do not consistently check the validity of the apps that they use. Residents also use social networks, with only a limited impact on their relationship with their patients. Overall, this study highlights the irruption and the risks of new technologies in the clinical practice and raises the question of a possible regulation of their use in the hospital.

    Full Text Available New technologies about ground improvements and thoughts on their economical repercussions. After an introduction on the importance of land and water improvement in the world, a synthesis is presented about the main contributions of new technologies at the levels of the preliminary investigations, the execution and the operation and management. At the level of the preliminary investigations, the contribution of electronics and computers is discussed as well for the data acquisition as for the data structuration, namely with the aid of data banks and numerical cartography. At the level of the execution, the laser technique for guidance of earthwork engines is discussed. At the level of operation and management, the support of new technologies consists of an increasing use of electronic sensors for local or remote control and monitoring of soil and plant water status. The laser technique is also used for the guidance of irrigation machines such as the central pivot. On an economical point of vue, these innovations don't seem to improve considerably the agricultural production per unit area, but they increase undoubtedly the productivity of the factor water. This is all the more true when the improved area is large. New technologies lead to scale economics. They are thus in favor of putting the land in common during the stages of investigations and excutions and to keep in common some aspects of the management.

    This document presents two estimates of future growth of emerging energy technology in the years 1985, 1990, and 2000 to be used as a basis for conducting Water Resources Council assessments as required by the Nonnuclear Energy Research and Development Act of 1974. The two scenarios are called the high world oil price (HWOP) and low world oil price (LWOP) cases. A national-level summary of the ASA tabulations is shown in Appendix A; the scenarios are presented at the ASA level of detail in Appendix B. The two scenarios were generally derived from assumptions of the Second National Energy Plant (NEP II), including estimates of high and low world oil price cases, growth rate of GNP, and related economic parameters. The overall national energy growth inherent in these assumptions was expressed as a detailed projection of various energy fuel cycles through use of the Fossil-2 model and regionalized through use of the Strategic Environmental Assessment System (SEAS). These scenarios are for the use of regional analysts in examining the availability of water for and the potential impacts of future growth of emerging energy technology in selected river basins of the Nation, as required by Section 13(a).

    With the seriousness of the climate change threat, the European Union has invited its member states to adopt the goal of dividing by a factor 4 their greenhouse gas emissions before 2050. France has answered this invitation and requested the De Boissieu Commission to make an inventory of the means allowing to reach this goal. A first debate took place at Grenoble on November 16, 2006 about the technological and industrial consequences of such a perspective and about the necessary R and D trends to be implemented (socio-economic impacts, changes in the sectors of transportation, dwellings, space heating, lighting and air-conditioning, role of nuclear and renewable energy sources). The results of these debates are summarized in this newsletter: what is Factor 4; what are the technological, economical and social implications; the achievable changes in the transportation sector; HOMES project: optimized dwellings and buildings for energy mastery and services; role of nuclear energy in the reduction of the fossil fuels share; rise in power of renewable energy sources.

    Offshore wind power has become an important component of the energy, industrial and climate policy of several countries surrounding the North Sea. In Norway, the political ambitions for offshore wind remains low, but several companies are nevertheless aiming for a position in the markets emerging nearby. This report addresses Norwegian companies positioning towards the emerging market for offshore wind in the North Sea to learn who they are, and how they approach a technology and market in the making. The report also briefly discusses how company managers assess the alignment between their position, and the Norwegian policy makers' positions and visions of offshore wind. The analysis shows that the majority of firms advocate experience based learning and development, while policy makers mainly stimulate R and D activities. The lack of a domestic market for offshore wind in Norway is seen as a barrier towards integration of experience-based and science-based learning, and impedes the momentum of technological and industrial development due to inadequate mutual understanding between the domains of industry, science, utility, politics and finance. The report is based on in-depth interviews (n=47) with managers of firms involved in offshore wind power as well as an e mail survey (n=147/325).(Author)

    This report to Congress was prepared on behalf of the Secretary of the US Department of Energy (DOE) in response to Sections 127 and 128 of the Energy Policy Act of 1992 (EPAct), Pub. L. 102-486. In preparing the report to the Congress, DOE has assessed the national and regional energy savings potential of products already on the market and those that will be available to consumers by the late 1990s. The Department has also examined the present cost-effectiveness of these emerging appliances as mature technologies. To help in its assessment, DOE organized eight workshops at which representatives from manufacturing and building industries, utilities, retailers and wholesalers, public interest groups and Federal and state government agencies could express their views. The information derived from these workshops was key to the formulation of the report`s general and specific recommendations. DOE has concluded that the Federal Government can effectively stimulate the market for emerging technologies by forming partnerships with the appliance industry and other interested parties promoting the use of highly efficient appliances. Based on the interaction with industry at the eight workshops and through direct contact, DOE has concluded that Federal action and technical assistance is not only desired by industry, but crucial to the expansion of these markets. Section 128 of EPAct requires an assessment of the energy savings and environmental benefits of replacing older, less efficient appliances with more efficient products than currently required by Federal law. Since early replacement of appliances is but one possible market-stimulating action, DOE has elected to include its discussion as part of the overall report to the Congress.

    Technology progresses made to reach new oil and gas resources (heavy crudes, buried deposits, ultra-deep offshore), to better exploit the available reserves (increase of the recovery ratio) and to reduce the costs will allow to enhance the hydrocarbon reserves and to durably extend the limits of the world energy supply. In a context where geopolitical uncertainties, high price rates and pessimistic declarations increase once again the public fear about petroleum reserves, the French institute of petroleum (IFP) wanted to make a status about the essential role that technology can play in this challenge. This document gathers the transparencies and articles presented at this press conference: how to increase and renew oil and gas reserves, technology advances and research strategy of IFP (O. Appert, J. Lecourtier, G. Fries); how to enhance oil recovery from deposits (primary, secondary and tertiary recovery: polymers injection, CO{sub 2} injection, steam injection, in-situ oxidation and combustion, reservoir modeling, monitoring of uncertainties); the heavy crudes (the Orenoque extra-heavy oil, the tar sands of Alberta, the heavy and extra-heavy crudes of Canada, IFP's research); ultra-deep offshore (the weight challenge: mooring lines and risers, the temperature challenge: paraffins and hydrates deposition, immersion of the treatment unit: economical profitability of satellite fields); fields buried beyond 5000 m (technological challenges: seismic surveys, drilling equipment, well logging, drilling mud; prospects of these fields); oil reserves: data that change with technique and economy (proven, probable and possible reserves, proven and declared reserves, three converging evaluations about the world proven reserves, reserves to be discovered, non-conventional petroleum resources, technical progress and oil prices, production depletion at the end of the century).

    Pregnancy and the postpartum period provide windows of opportunity to impact perinatal and lifelong preventive health behavior for women and their families, but these opportunities are often missed. Understanding racial/ethnic differences in information and communication technology (ICT) use could inform technology-based interventions in diverse populations. The objective of the study was to evaluate differences in the use of ICT between racial and ethnic groups as well as by English language proficiency. We conducted a cross-sectional study of 246 women who were aged 18 years or older and pregnant or within 1 year of delivery. They were recruited from 4 hospital-based outpatient clinics and completed a self-administered survey. We used multivariate regression analysis to evaluate the association between race/ethnicity and ICT (mobile phone/short message service [SMS] text message, Internet, and social network) usage by race/ethnicity and perceived English language proficiency after adjusting for age, income, marital status, and insurance status. In all, 28% (69/246) of participants were Latina, 40% (98/246) were African American, 23% (56/246) were white, and 9% (23/246) from other racial/ethnic groups. Of the Latinas, 84% (58/69) reported limited English language proficiency and 59% (41/69) were uninsured. More than 90% of all participants reported mobile phone use, but more than 25% (65/246) had changed phone numbers 2 or more times in the past year. Compared to white women, African American women were less likely to SMS text message (OR 0.07, 95% CI 0.01-0.63) and Latinas were less likely to use the Internet to find others with similar concerns (OR 0.23, 95% CI 0.08-0.73). Women with limited English language proficiency were less likely to use the Internet overall (OR 0.30, 95% CI 0.09-0.99) or use email (OR 0.22, 95% CI 0.08-0.63) compared to women with adequate English language proficiency.

    Le thème central de la thèse est la mesure de la section efficace de production des électrons venant de la désintégration des quarks lourds (b et c) avec l'expérience ATLAS dans les collisions proton-proton à sqrt(s)=7 TeV au LHC. La calibration du calorimètre électromagnétique et la reconstruction des électrons jouent un rôle cardinal dans l'analyse développée dans cette thèse. Ces thématiques sont traitées dans la première partie du manuscrit. L'étude des systématiques liées à la variation des constantes de calibration paramètrant la chaîne de lecture du calorimètre et qui affectent la reconstruction de l'énergie des cellules est presentée. La description des procédures de reconstruction des événements dans le détecteur ATLAS est ensuite traitée. Les cas de mauvaise reconstruction sont abordés et une étude de l'estimation du taux des faux leptons dans des événements multi-jets est présentée. La deuxième partie de la thèse est dédiée à la mesure de la section ef...

    The authors present a measurement of the t{bar t} production cross section in p{bar p} collisions at {radical}s = 1.96 TeV which uses events with an inclusive signature of significant missing transverse energy and jets. This is the first measurement which makes no explicit lepton identification requirements, so that sensitivity to W {yields} {tau}{nu} decays is maintained. Heavy flavor jets from top quark decay are identified with a secondary vertex tagging algorithm. From 311 pb{sup -1} of data collected by the Collider Detector at Fermilab they measure a production cross section of 5.8 {+-} 1.2(stat.){sub -0.7}{sup +0.9}(syst.) pb for a top quark mass of 178 GeV/c{sup 2}, in agreement with previous determinations and standard model predictions.

    The effect of rapid carcass chilling on breast meat quality was evaluated using commercial (COMM) and random-bred (RB) turkeys. Immediately after slaughter, 48 turkeys from COMM or RB line were randomly subjected to one of four chilling methods: 1) water-immersion chilling (WIC) of the carcasses at 0°C ice slurry, 2) WIC after temperature abuse (TA) of the carcasses at 40°C for 30 min (TA-WIC), 3) hot-boning, quarter sectioning, and crust-freeze-air-chilling (HB-(1)/4CFAC) of breast fillets at -12°C, and 4) HB-(1)/4CFAC of fillets after TA of carcasses (TA-HB-(1)/4CFAC). The TA increased carcass and fillet temperatures by ∼1.3 and ∼4.1°C, respectively, regardless of turkey line, whereas HB-(1)/4CFAC of fillets required 28 and 33% of carcass chilling time for COMM and RB, respectively. During chilling, COMM breast pH rapidly reduced from 6.04 to 5.82, resulting in a significantly lower pH than RB after chilling (P 0.05). Significantly higher L* value and cooking yield (P 0.05). Higher values of hardness, gumminess, and chewiness were found for RB, no TA, and HB-(1)/4CFAC gels than COMM, TA, and WIC, respectively. These results generally indicated that protein quality and textural properties of turkey fillets were improved, regardless of strains or temperature abuse, using HB-(1)/4CFAC technology. © 2015 Poultry Science Association Inc.

    Full Text Available Abstract Background While a possible link between assisted reproductive technology (ART and rare imprinting disorders has been found, it is not clear if this is indicative of subtler disruptions of epigenetic mechanisms. Results from previous studies have been mixed, but some methylation differences have been observed. Methods Children conceived through ART and children conceived spontaneously were recruited for this cross-sectional study. Information about reproductive history, demographic factors, birth characteristics, and infertility treatment was obtained from maternal interview and medical records. Peripheral blood lymphocytes and buccal cell samples were collected from participating children. Methylation analysis was performed on five loci using pyrosequencing. Statistical analysis of methylation differences was performed using linear regression with generalized estimating equations. Results are reported as differences with 95% confidence intervals (CI. Results A total of 67 ART children and 31 spontaneously conceived (SC children participated. No significant difference in methylation in lymphocyte samples was observed between groups for any loci. Possible differences were found in buccal cell samples for IGF2 DMR0 (Difference: 2.07; 95% confidence interval (CI: -0.28, 4.42; p = 0.08 and IGF2R (Difference: -2.79; 95% CI: -5.74, 0.16; p = 0.06. Subgroup analysis indicated potential lower methylation in those whose parents used ART for unexplained infertility. Conclusions Observed differences in methylation between the ART and SC groups were small for all loci in the two sample types examined and no statistical differences were observed. It is still unclear whether or not small differences observed in several studies represent a real difference between groups and if this difference is biologically meaningful. Larger studies with long term follow-up are needed to fully answer these questions.

    There is no longer any doubt about the connection between carbon dioxide emissions of human origin and global warming. Nearly 40% of world CO{sub 2} emissions are generated by the electricity production sector, in which the combustion of coal - developing at a roaring pace, especially in China - accounts for a good proportion of the total. At a time when the reduction of greenhouse gases has become an international priority, this growth is a problem. Unless CO{sub 2} capture and storage technologies are implemented, it will be very difficult to contain global warming.

    In this report, we summarise our research program within the ATLAS collaboration between 2005-2012. We summarise our contribution to the integration of two of the Inner Detector sub-detectors, the SCT and the TRT. We describe also our contribution to the optimisation and tuning of the jet reconstruction in the harsh ATLAS environment. We compare the performances of these different algorithms. Finally, with the data collected at a centre of mass energy of 7 TeV, we extract the top-anti-top production cross section in the challenging all-hadronic decay channel.

    In hadronic physics, the nucleon structure and the quarks confinement are still topical issues. The neutral pion electroproduction and virtual Compton scattering (VCS) reactions allow us to access new observables that describe this structure. This work is focussed on the VCS experiment performed at Jefferson Lab in 1998. The 4 GeV electron beam is scattered off a cryogenic hydrogen target, and the scattered electron and recoiled proton are detected in coincidence in the twin hall A spectrometers. The photon (pion) is reconstructed using a missing particle technique. The data analysis allowed to extract the cross sections relative to both process at four-momentum transfer squared Q{sup 2} = 1 GeV{sup 2}. The VCS cross section has been extracted for the first time in the proton resonance region (W between 1.O and 2.0 GeV) through the photon electroproduction reaction. Around the pion-production threshold up to the Delta(1232) resonance region, these results lead to the measurement of the generalized polarizabilities, that describe the proton structure in the same way as the elastic form factors. Moreover, the neutral pion electroproduction cross section measurement in the resonance region has brought new constraints on the existing phenomenological models. (author)

Comment et dans quelle mesure l’ADN est-il endogénéisé, par le biais de l’expertise judiciaire, dans la justice et quels en sont les effets sur les raisonnements et les pratiques judiciaires ?

    A modular system, MECCANO, has been developed at the Laboratoire de l`Accelerateur Lineaire d`Orsay to study the physical and technical phenomena of high electric fields in travelling waves structures in the context of future linear colliders which can reach TeV energies. The behaviour of the electric field inside the section MECCANO is considered from the theoretical point of view with numerical simulations and analytical representations and from the experimental side with low and high power measurements. An infinite and uniform structure is classically described by series of RLC resonant circuits. The basic RF properties of the fundamental mode are given. For a finite section, the matching of a forward or backward travelling wave of any phase advance per cell is also represented by means of RLC circuits. The variations of the reflection and transmission properties of the structure with frequency and a new procedure to match couplers have been modelled and experimentally verified. The electromagnetic behaviour of each cavity and of the whole structure have been studied, the fundamental and first high order modes have been simulated by 2D or 3D codes and measured at low power. The matching of the phase, the amplitude and the reflection level of the accelerator is described. This procedure is found to be extremely delicate due to the abrupt changes in the geometry of the cavities. The structure has been tested at fields superior to 150 MV/m. The behaviour of some materials and surface layers subject to high gradients are presented. (author) 46 refs.

    One of the main challenges of the current and future colliders TeVatron and LHC is the discovery of physics beyond the Standard Model. This goal may be accessible through precision measurements in the top quark sector. Deviations from theoretical predictions may bring to light the first indirect signs of new physics. The work exposed in this thesis deals with the production cross-section of top quark pairs via the strong interaction, within both D0 and ATLAS collaborations. Firstly, I have worked at D0 on the improvement of the reconstruction of soft electrons, in order to tag b-jets produced in top-anti top quarks events. Then I focused myself on the measurement of the top quark pair production cross-section with 420 pb{sup -1} of D0 data. The measured cross-section is in agreement with the Standard Model expectations. In the ATLAS experiment, I tried to develop a procedure in order to select top quark pair events, using the knowledge and the techniques from the D0 experiment. This work also high-lighted the main systematic sources that can affect the sensitivity of the measurement. After one year of data taking at low luminosity, this preliminary analysis obtains a sensitivity at a few percent level, leading to a good discovery potential of new physic signs, like charged Higgs bosons. These new particles appear in non minimal standard models, and modify the phenomenology of top pair events. This new analysis has shown a good sensitivity for some regions of the parameter space.

    De Bonnis, Isabelle

    I describe in this HDR the scientific works that I have done since my PhD, defended in 1994. The first part of these works was devoted to the development of detectors within the BaBar experiment. The second part, more extensively described here, was the study of the di-leptonic events produced in the ALEPH experiment at LEP2. In the BaBar experiment, I initially contributed to the feasibility study of a Cerenkov counter dedicated to the identification of charged particles. I had then the responsibility of the construction of a wire chamber for the monitoring of the gain, installed in the gas distribution system of the BaBar drift chamber. These activities included design and simulation of instruments as well as analysis of tests data. Then, I participated to the LEP2 data analysis by measuring cross-sections and forward-backward asymmetries of the di-leptonic processes. I made the interpretation of these measurements under various scenarios of new physics beyond the Standard Model, such as four fermions conta...

    The LHC, which is the most powerful proton-proton collider in the world located at CERN (Switzerland), brings unprecedented opportunities to test our knowledge of the fundamental interactions at the TeV scale. In this work, two main projects have been achieved for this purpose. First, the production cross section measurement of at least two photons in the final state ($pp\\rightarrow\\gamma\\gamma+X$) is performed with data taken at a center-of-mass energy of 8 TeV by the ATLAS detector, which is one of the multipurpose detector installed around the LHC ring. Photons are interesting probes to test the theory of strong interactions (Quantum chromodynamics or QCD) since they couple significantly to quarks but do not hadronize and thus still allow to perform high resolution measurements. The measurement of their production rate at the LHC allows to test QCD in both the perturbative and the non-perturbative domain. It is also sensitive to the emission of soft particles in the initial-state, which is tricky to handle...

    The abatement of CO{sub 2} emissions is a huge technical and economical challenge. Fossil fuels, which represent 88% of the world primary energy consumption, are the main source of the 25 billions of CO{sub 2} released each year in the atmosphere. The mastery of CO{sub 2} emissions cannot come from a single technology but must result from the simultaneous implementation of several means, like the development of carbon-free energies and the mastery of fossil fuel emissions. The opportunities of progress are numerous and compatible with the economic development. This document presents, first, the different greenhouse gases, the CO{sub 2} emissions per country and the main sources of CO{sub 2} emissions (power and heat generation, transports). Then it presents different ways of abatement of CO{sub 2} emissions: clean coal technologies, gas combined cycles, CO{sub 2} sequestration, reduction of fuel consumption in transports, development of carbon-free energies: wind power, solar photovoltaic for decentralized power generation, nuclear energy for a competitive power generation and for CO{sub 2} abatement, biofuels of 2. generation and fuel cells. The conclusion stresses on the investments needed for the renewal and increase of energy capacities, and on the necessary visibility and moderation of emission abatement mechanisms (carbon trading and CO{sub 2} prices).

    This work is devoted to the precision tests of the electro-week sector of the standard model via the determination of the Z-lineshape parameters M{sub Z}, {gamma}{sub Z}, {sigma}{sub had}{sup 0} and R{sub had} extracted from the fermionic cross-sections measured on 89 to 94 data in Aleph. The first section reminds the formalism and the observables used to describe the Z-resonance physics. In a second step, the LEP collider is presented with the procedures used to determine the beam energy, this parameter being the main source of uncertainty in M{sub Z} and {gamma}{sub Z} determination. In the following part, the Aleph experimental context is described, together with the measurement of the luminosity from Bhabha counting. Then the hadronic cross section measurements are presented, emphasizing on the improvement performed on the systematic bias evaluation to the hadrons selection. This leads to a precision at the per mille level in cross-sections. Leptonic cross-sections measured in Aleph are also reported. The Z-resonance parameters are then derived. A great agreement is observed with the prediction of the standard model of the EW interactions. The interpretation of such measurements within this model leads to the determination of the number of light neutrinos species and to the constraints on the top quark mass, compatible with direct measurements from Fermilab.

    The endothelial cells release both relaxing [nitric oxide (NO), endothelium-derived hyperpolarizing factor (EDHF), prostacyclin] and contracting factors [endoperoxides, thromboxane A(2), superoxide anions, endothelin-1 (ET)]. The production of ET is inhibited by NO. The latter also strongly opposes the direct effects of the former on vascular smooth muscle. With aging and vascular disease, the production of enothelial NO declines, and thus ET can be released, act and contribute to the symptoms.

    The inclusive cross sections for both charged and neutral current processes have been measured in interactions of longitudinally polarized electrons (positrons) with unpolarized protons using the full data samples collected by H1 at HERA-II. The data taken at a center-of-mass energy of 319 GeV correspond to an integrated luminosity of 149.1 pb{sup -1} and 180.0 pb{sup -1} for e{sup -}p and e{sup +}p collisions, representing an increase in statistics of a factor of 10 and 2, respectively, over the data from HERA-I. The measured double differential cross sections d{sup 2}{sigma}/dxdQ{sup 2} cover more than two orders of magnitude in both Q{sup 2}, the negative four-momentum transfer squared, up to 30000 GeV{sup 2}, and Bjorken x, down to 0.003. The cross section data are compared to predictions of the Standard Model which is able to provide a good description of the data. The polarization asymmetry as a function of Q{sup 2} is measured with improved precision, confirming the previous observation of P violation effect in neutral current ep scattering at distances down to 10{sup -18} m. The total cross sections of the charged current process, for Q{sup 2} > 400 GeV{sup 2} and inelasticity y < 0.9 are measured for 4 independent data samples with e{sup {+-}} beams and different polarization values. Together with the corresponding cross section obtained from the previously published unpolarized data, the polarization dependence of the charged current cross section is measured and found to be in agreement with the Standard Model prediction with the absence of right-handed charged current. The cross sections are combined with previously published data from H1 to obtain the most precise unpolarized measurements. These are used to extract the structure function xF{sub 3}{sup {gamma}}{sup Z} which is sensitive to the valence quark distributions down to low x values. The new cross sections have also been used in a combined electroweak and QCD fit to significantly improve the

Measurement of the efficient cross section of the reaction {sup 7}Be(p, {gamma}){sup 8}B at low energies and implications in the problem of solar neutrinos; Mesures de la section efficace de la reaction {sup 7}Be(p,{gamma}){sup 8}B a basses energies et implications dans le probleme des neutrinos solaires

    The {sup 8}B produced inside the sun through the reaction {sup 7}Be(p,{gamma}){sup 8}B is the main, and even unique, source of high energy neutrinos detected in most solar neutrino detection experiments, except with Gallex and Sage. These experiments have all measured a neutrinos flux lower than the one predicted by solar models. Several explanations have been proposed to explain this deficit, but all require a precise knowledge of the efficient cross-section of the reaction {sup 7}Be(p,{gamma}){sup 8}B, because the neutrinos flux of {sup 8}B is directly proportional to this reaction. The direct measurement of this cross section for the solar energy is impossible because of its low value (about 1 femto-barn). In order to get round this problem, the cross sections are measured at higher energy and extrapolated to the solar energy using a theoretical energy dependence. The 6 previous experimental determinations of the efficient cross section were shared in two distinct groups with differences of about 30% which leads to an uncertainty of the same order on the high energy neutrinos flux. The re-measurement of the cross section of this reaction with a better precision is thus of prime importance. A direct measurement of the cross section in the energy range comprised between 0.35 and 1.4 MeV (cm) has been performed first. These experiments have permitted the precise measurement of each parameter involved in the determination of the cross section. Then, measurements of the cross section have been carried out with the PAPAP accelerator at 185.8, 134.7 and 111.7 keV, the lowest mass center energy never reached before. The results are in excellent agreement with those obtained at higher energies. The value obtained by extrapolation of these data for the astrophysical factor S{sub 17}(0) is 19.21.3 EV-B, which leads to a significant reduction of the uncertainty on the high energy neutrinos flux of {sup 8}B.

    Nutritional benefits of cultivated oat (Avena sativa L., 2n = 6x = 42, AACCDD) are well recognized; however, seed protein levels are modest and resources for genetic improvement are scarce. The wild tetraploid, A. magna Murphy et Terrell (syn A. maroccana Gdgr., 2n = 4x = 28, CCDD), which contains approximately 31% seed protein, was hybridized with cultivated oat to produce a domesticated A. magna. Wild and cultivated accessions were crossed to generate a recombinant inbred line (RIL) population. Although these materials could be used to develop domesticated, high-protein oat, mapping and quantitative trait loci introgression is hindered by a near absence of genetic markers. Objectives of this study were to develop high-throughput, A. magna-specific markers; generate a genetic linkage map based on the A. magna RIL population; and map genes controlling oat domestication. A Diversity Arrays Technology (DArT) array derived from 10 A. magna genotypes was used to generate 2,688 genome-specific probes. These, with 12,672 additional oat clones, produced 2,349 polymorphic markers, including 498 (21.2%) from A. magna arrays and 1,851 (78.8%) from other Avena libraries. Linkage analysis included 974 DArT markers, 26 microsatellites, 13 SNPs, and 4 phenotypic markers, and resulted in a 14-linkage-group map. Marker-to-marker correlation coefficient analysis allowed classification of shared markers as unique or redundant, and putative linkage-group-to-genome anchoring. Results of this study provide for the first time a collection of high-throughput tetraploid oat markers and a comprehensive map of the genome, providing insights to the genome ancestry of oat and affording a resource for study of oat domestication, gene transfer, and comparative genomics.

    Full Text Available The range and number of technologies currently available have yielded both opportunities and challenges for language educators. This study aims to review recent technology-enhanced language learning (TeLL research, and to examine their potential relevance to EAP pedagogy, curricula, assessment and instruction. The results of this study show TeLL research with rising interest in vocabulary, grammar and writing, but less so in speaking, listening, and reading. The results also reveal a shift from a tool-centric view of technology use to one that emphasises the technology-pedagogy-human alliance in the last decade, noting three emerging trends in recent TeLL studies, namely, those that are multi-purpose, multi-genre, and multi-role/skill in design and evaluation. The lack of a holistic approach to TeLL for EAP courses to date, however, has made it necessary and desirable to develop a framework for EAP-specific TeLL, to identify a principle for a generic TeLL programme, and to propound ways of operationalizing such a framework.

    In the framework of the experimental research for the quark and gluons plasma formation in ultrarelativistic heavy ion collisions, data obtained by the NA50 collaboration at SPS-CERN are analysed. The segmented target used by NA50 experiment is described and analysed in terms of vertex identification efficiency and re-interactions recognition. The absolute J/{psi}, {psi}`and Drell-Yan process cross-sections in 158 GeV/c per nucleon Pb-Pb interactions are extracted. The transverse energy dependence of the production yield of J/{psi} and Drell-Yan process is established. The comparison of these cross-sections with the ones measured in lighter systems and the comparison of the E dependence of J/{psi} production with the Glauber model prediction show an anomalous J/{psi} suppression observed in Pb-Pb interactions is confronted to theoretical models proposed by several authors, describing charmonium bound states formation and interactions is confronted to theoretical models proposed by several authors, describing charmonium bound states formation and interactions in confined or deconfined media.

    Using the direct method, the mean energy integrated reaction cross section was investigated for a wide range of neutron-rich nuclei (N {yields} Ar) at GANIL. Using the parametrisation of S. Kox, 19 new radii measurements (reaction cross sections) were obtained. By the isotopic, isotonic and isospin dependence, the evolution of the strong reduced radius was studied according to the excess of neutrons. New halo effect is proposed to the nuclei of Mg{sup 35} and S{sup 44}. A quadratic parametrization is also proposed for the nuclear radius as a function of the isospin in the region of closed shells N=8 and N=28. In addition, we used a modified version of the Glauber model for studying the tail and matter distribution of nuclei. Indeed, using our new data the effects of the nuclear size (root mean square radii) and the matter distribution (diffusivity) were de-convoluted for each isotope. The root mean square radii of Na and Mg isotopes obtained so far were consistent with the ones from literature. (author)

    The Generalized Parton Distributions (GPDs), introduced in the 1990's, provide the most complete description of the structure (in quarks and gluons) of the nucleon. The Deeply Virtual Compton Scattering (DVCS), which corresponds to the 'hard' exclusive electroproduction of photons on the nucleon, is a key process among the reactions allowing access to the GPDs. A DVCS-dedicated experiment was carried out in 2005 with the CLAS detector of Jefferson Lab, using a polarized electron beam of 5.776 GeV and a hydrogen target. For this experiment, we built and used a dedicated electromagnetic calorimeter capable of detecting the final-state photon. The collected data allowed us to study the DVCS in the widest kinematic range ever accessed for this reaction: 1 < Q{sup 2} < 4.6 GeV{sup 2}, 0.1 < x{sub B} < 0.58, 0.09 < -t < 2 GeV{sup 2}. The work performed during this PhD includes simulation work done for the preparation of the experiment, timing calibration of one of the CLAS subsystems, and data analysis. The aim of the data analysis was the extraction of the unpolarized cross sections of the studied reaction and of the difference of the polarized cross sections, this latter observable being linearly proportional to the GPDs. The obtained results were compared to DVCS theoretical calculations based on one of the most up-to-date GPD parametrizations. (author)

    This thesis comes within the framework of minor-actinide nuclear transmutation studies. First of all, we have evaluated the impact of minor actinide nuclear data uncertainties within the cases of {sup 241}Am and {sup 237}Np incineration in three different reactor spectra: EFR (fast), GT-MHR (epithermal) and HI-HWR (thermal). The nuclear parameters which give the highest uncertainties were thus highlighted. As a result of fact, we have tried to reduce data uncertainties, in the thermal energy region, for one part of them through experimental campaigns in the moderated high intensity neutron fluxes of ILL reactor (Grenoble). These measurements were focused onto the incineration and transmutation of the americium-241, the curium-244 and the californium-249 isotopes. Finally, the values of 12 different cross sections and the {sup 241}Am isomeric branching ratio were precisely measured at thermal energy point. (author)

    The tagging of heavy flavour quarks is crucial for several standard model studies such as the Higgs boson identification through its decay into b quark pairs, or top quark studies. The reconstruction of electrons and muons inside jets is one of the tools used for heavy flavour tagging. In D0 at Run-1, only soft muon tagging was possible since there was no magnetic field in the central detector. The detector has been upgraded for Run-2, and heavy flavour tagging with electrons became possible thanks to a new superconducting magnet. I developed the so-called road algorithm for this purpose. It benefits from the new capability of the tracker and from the good calorimeter properties. Its performance are studied in detail with generated events as well as with real data. The identification efficiency and the mis-identification rate are determined with physics signals. The capability of the road method for b tagging is demonstrated. Heavy flavour tagging with leptons in jets can be efficiently applied to the top quark 'rediscovery'. Indeed, the leptons from semi-leptonic decays of b quarks are very hard and central. The analysis is carried out in the electron-plus-jet and muon-plus-jet channels simultaneously. For the first measurement of the cross section of top quark production in Run-2, only the tagging with muons is used. The measured value for the cross section of tt-bar production at {radical}s 1.96 TeV is 8.5 (+4.5-3.6)(stat) (+6.3-3.5)(sys) ({+-}0.8)(lumi) pb. The tagging with electrons requires a specific optimization, but once it is performed the good efficiency of the road method is confirmed. Several ways to improve it are proposed. One of the most promising is the extension of the road method to the pre-shower detectors. (author)

    The work presented in this thesis concerns the measurement of the top-anti-top production cross-section in the lepton + jets channel (electron and muon). The analysed data have been collected with the D0 detector between 2001 and 2004 at a center-of-mass energy of 1.96 TeV, at the Tevatron proton-antiproton collider located at Fermilab. These data correspond to an integrated luminosity of 160 pb-1 in each channel. Each top quark decays into a W boson and a b quark. The first part of this work has been focused on the elaboration of an algorithm, JLIP, aimed at identifying jets arising from b quark s decay products. This algorithm uses the impact parameter of the track s to assign a jet a probability that it originates from the primary interaction point. Its efficiency for top-anti-top events is about 45% with a rejected background of 99.7%. The second part of this work deals with the pre-selection step that allows isolating events which are likely to be compatible with a W+jets topology. Multi-jets and W+jets backgrounds are estimated from real data and simulation. The top pair production cross-section is extracted from candidate events that have at least three jets, one among them being tagged by the algorithm JLIP. Sources of systematics uncertainties have been studied in detail. Our results are the following, for the lepton + jets channel: {sigma}(tt-bar) = 8.28 (+1.31-1.21, stat) (+1.53-1.27, syst) (+0.53-0.53, lumi) pb. Results have been compared with the theoretical expectations and with other measurements performed in the D0 and CDF experiments. (author)

    An international benchmark exercise was launched by ITER Joint Central Team for an experimental validation of the integral decay power heat for fusion relevant materials irradiated in 14 MeV neutron spectra. In this paper, we compare the results of JAERI/FNS decay heat experiments performed upon Eu{sup 203} sample with calculations done with the inventory code FISPACT-2005 using two different cross section evaluations for the isotope {sup 151}Eu and {sup 153}Eu, namely EAF-2005 and BRC6(CEA/DAM). In order to estimate the difference between the calculated and the experimental decay heat values and the impact on the calculation results by the two different activation libraries adopted in the present work, the percentage ratios (C-E)/E % have been deduced and are presented. The outcome is the validation of the BRCD6 europium activation nuclear data by the adopted computational approach which provides a better agreement with the experiment than the EAF one, despite a low energy neutron flux uncertainty.

    This thesis works is part of the precision tests done at LEP2. The W{+-} boson pairs are produced through e{sup +}e{sup -} collisions. The fully leptonic final states (l{nu}-bar l-bar{nu}) correspond to 10.5 % of the disintegrations. This channel is added to the hadronic and semi-leptonic channels, allowing a constraint on the Standard Model. Data recorded between 1996 and 1998 by the ALEPH detector are used to select the l{nu}-bar l-bar{nu} final states, characterised by two energetic coplanar charged leptons and large transverse missing momentum. The fully leptonic cross-sections are determined in view of the measurement of the W`s branching ratios. Contrary to the TEVATRON`s measurements, the branching ratios are determined without universality constraint on W couplings. Presently, LEP obtains the best precision on the measurement of the W`s branching ratios. No deviation was observed with respect to the Standard Model predictions. (author) 85 refs.

    Collisional excitation cross-sections are essential for the modeling of the properties of non equilibrium plasmas. There has been a lot of work on electron impact excitation of isolated ions, but in dense plasmas, neighboring particles are expected to widely disturb these electron transitions in atoms. Plasma modeling through a radially perturbed potential has already been done but is not satisfactory as it does not account for levels degeneracy breaking and its consequences. Introduction of a quasistatic electric micro-field of neighboring ions allows us to break spherical symmetry. Our original theoretical study has given birth to a numerical code that accurately computes collisional strengths and rates (in the Distorted Waves approach) in atoms submitted to a realistic micro-field. Hydrogen- and helium-like aluminium is studied. Stark mixing widely increases rates of transitions from high l levels and forbidden transitions are field-enhanced by many orders of magnitude until they reach allowed ones. Eventually, we conduct an elementary stationary collisional radiative study to investigate field-enhancement effects on corresponding line shapes. In cases we study (aluminium, hydrogen- and helium-like) we find a relatively weak increase of K-shell line broadening.

    Full Text Available Dans la culture homosexuelle masculine, drague et cruising sont des termes équivalents. Ils désignent la quête d’un ou de plusieurs partenaires occasionnels et anonymes. Analyser leurs référents métaphoriques respectifs offre un éclairage particulier, à la fois phénoménologique et géographique, pour une compréhension nuancée des types de pratique et d’expérience qu’ils recouvrent. Cet article pose l’hypothèse d’une distinction entre deux figures, le dragueur et le cruiser, et postule que cette distinction se tient essentiellement dans l’opposition que Gilles Deleuze et Félix Guattari établissent entre ‘espace strié’ et ‘espace lisse’. L’essai de théorisation qui en découle est une manière de comprendre ce qui, entre sexualisation de l’espace et érotisation d’un mouvement exploratoire, fait fonctionner le script de la drague.In French gay culture, drague means cruising: looking for anonymous and 
casual sexual partners. This paper, by respectively examining the 
metaphorical underpinnings of both words, French and English, throws 
doubt on the validity of this translation. Through a phenomenological 
and geographical perspective, it attempts to give a nuanced examination 
of the practice and experience that each word conceals. The aim is to 
identify two figures embodied in a same person: the dragueur and the 
cruiser. I will argue that the distinction mainly rests on the 
opposition that Gilles Deleuze and Felix Guattari establish between ‘striated space’ and ‘smooth space’. The concluding theorical 
discussion is an attempt to understand what, in the tension between sexualization of space and eroticization of movement, guides the scripts of drague and cruising.

Porteurs de performances spécifiques et de caractéristiques plus écologiquement correctes, leur emploi ouvre à l’industrie un potentiel d’innovations auquel participe le département de chimie et rhéologie de l’Iterg. La prise de conscience collective, associée aux évolutions des réglementations françaises et européennes, devrait conduire les industries à prendre de plus en plus en compte le respect de l’environnement dans leurs activités. La substitution de dérivés pétrochimiques par des produits d’origine agricole dans certains secteurs industriels (détergence, lubrifiants, solvants notamment contribue à la protection de notre environnement : diminution des volumes de déchets et des effluents, lutte contre l’effet de serre, moindre écotoxicité, innocuité pour la santé. De plus, l’épuisement latent des ressources pétrolières et la pratique de la jachère ont permis d’accélérer le développement de nouvelles voies de valorisations des huiles végétales et plus largement des agroressources. Les enjeux, à l’horizon 2010, sont bien plus importants encore pour ces produits, qui de part leur fonctionnalité spécifique, ont vocation à continuer d’occuper des marchés de niche. D’ici 10 ans, 2 à 3 millions d’hectares pourraient être consacrés à l’industrie du végétal \\; il s’agit là d’une véritable stratégie de développement durable qui nécessite un soutien politique, une vision à long terme et une motivation forte de l’industrie.

    femtosecond lasers operating at high repetition rate (~100 MHz). The system described by Planken et al was initially optimized for high-speed pixel-by-pixel THz imaging, which they do not describe here but rather focus on developments in THz microscopy. The second paper, by Kübler et al, presents pioneering work towards ultra-wide-bandwidth THz pulses which exhibit spectral content reaching far into the mid-IR, tremendously widening the covered frequency range, and hence shortening the time resolution, of THz spectroscopy. The third paper, by Löffler et al, deals with the state of the art in THz measurement systems relying on amplified laser pulses. Finally, Krotkus et al focus on low-temperature-grown (LT) GaAs, arguably the most important material for ultrafast optoelectronic switching and present in many THz sources and detectors, and in other emerging materials of similar kind. This leads directly to the second topic of this collection of papers, 'Continuous-Wave Photomixing Technology', based on THz-wave generation by down-conversion of continuous-wave (cw) laser radiation. This newer branch of THz photonics opens the possibility of obtaining tunable narrow-band THz radiation and of detecting it with high signal-to-noise ratio at room temperature. CW photomixing has received much attention over the last few years mainly because it has the potential to provide the compact and low-cost THz measurement systems needed for market applications beyond the scientific realm, with the sources of light for mixing being semiconductor (or fibre) lasers with or without optical amplifiers. Six papers outline recent developments in this subfield. We should also point towards a seventh paper, by Kawase et al, which is to be found in the section on 'Chemical and Biochemical Recognition', and which discusses an interesting hybrid approach generating tunable quasi-cw THz radiation with the help of nanosecond laser pulses. Of the six papers mentioned, the first, by Tani et al, summarizes

    In the first part of this experiment, we determined the total cross section for processes yielding only neutral particles, from 300 to 1600 MeV. For this, we counted the number of incident {pi}{sup -}, as defined by a counter telescope, which interact in a liquid-hydrogen target without giving charged particles in a 4{pi} counter surrounding the target. In the second part of this experiment, we have separated the reaction {pi}{sup -} p {yields} {pi}{sup 0} n and {pi}{sup -} p {yields} {pi}{sup 0} {pi}{sup 0} n between 300 and 1100 MeV, by supposing that only these two reactions was realized by placing lead absorbers between the target and 4{pi} counter and by comparing the counting rate for neutral events with and without lead. The transmission thus measured is a function of the average number of photons produced and therefore of the ratio between the two neutral channels, {pi}{sup 0} n and {pi}{sup 0} {pi}{sup 0} n. In the last section of this work, we discuss the experimental results and compare them to those obtained by other authors in the study of photoproduction and the {pi}-nucleon interaction.

    Taillant, P.

    2001-10-01

    In this study, the evolutionistic model of technological competition of B. Arthur is used to analyze the phenomena of increasing efficiency of adoption and the technological lock-in situation in the sector of photovoltaic cells for power generation. The processes of path dependence and random historical factors, like the public orders, can lead to a situation where the dominating technology is not necessary the most efficient. In the case of solar photovoltaic, the dominating 'crystalline silicon' technology is the one that has today the best energy efficiency. However, taking into account the evolution of its experience curve which shows a beginning of exhausting of the learning effects, the perspectives of cost reduction seem to be limited despite a sustained demand and intense R and D activities. On the other hand, the thin film technology, with lower efficiencies, would gain in competitiveness thanks to the automation of manufacturing processes. In these circumstances, the technological public policies have to maintain a diversity in the choice of possible technologies in order to allow the promising, but less attractive today, technologies to develop in the future.

    Cet ouvrage donne une présentation unifiée de la thermodynamique et de la physique statistique. Au point de vue historique, la thermodynamique macroscopique a précédé la physique statistique qui adopte, elle, un point de vue microscopique. Des concepts tels que chaleur, énergie interne, entropie, introduits sans interprétation microscopique, peuvent paraître trop abstraits et rebuter un débutant. Ici, on a préféré donner des notions simples sur la physique statistique (c'est-à-dire se placer à l'échelle atomique) pour en déduire les principes de la thermodynamique.

    Le feu d'artifice qui se déroule à la fin des Vacances de Monsieur Hulot compte parmi les plus frustrants de l'histoire du cinéma. Il éclate prématurément. Sa chorégraphie se déploie dans une incoordination totale. Et dans l'absence, puisque son public est plongé dans le sommeil. Le son même est parasité par des bruits de tirs, de canonnades et de bombardements qui tirent le spectacle vers le registre guerrier. Cette congruence dissonante (ou encore ce « relief moral », dirait André Bazin) su...

    Full Text Available Cet article se propose d’aborder la question de la militance chez les femmes aînées à partir des résultats d’une recherche qualitative menée au Québec, Canada, sur trois ans (2005-2008. Alors que les aînées d’aujourd’hui appartiennent à une génération de femmes qui ont ouvert de multiples portes et ont investi de nouveaux espaces publics, on s’est peu intéressé à leurs pratiques et au sens de leurs engagements après 65 ans. Après avoir introduit la question de la participation sociale et citoyenne des personnes âgées en général, et plus particulièrement des femmes âgées, les auteures mettent en évidence les principales caractéristiques de leurs engagements militants et de leurs conceptions du monde ; un monde qu’elles rêvent encore de changer. Une attention particulière est portée à la perception qu’ont les aînées des différences liées au genre et à la génération. En effet, bien que la plupart d’entre elles ne se définissent pas comme étant des retraitées ni des féministes, elles considèrent que leurs formes et leurs pratiques de militance se distinguent de celles des jeunes militantes et de leurs homologues masculins.Este artículo tiene como objetivo analizar la cuestión de la militancia de las mujeres mayores de 65 años.

A quels changements cette rupture nous contraint-elle en ce qui concerne des notions essentielles, telles celles d'espace, de temps, d'objet et d'objectivité ? Quelles en sont les incidences quant à la portée de la connaissance, au rôle de la conscience, aux relations entre science et ontologie ? Ce sont là des questions de fond, fort délicates, auxquelles les personnes de tendance quelque peu philosophique sont plus sensibles que ne le sont les physiciens.

    Carbonaceous chondrite meteorites have long posed a challenge for thin section makers. The variability in sample hardness among the different types, and sometimes within individual sections, creates the need for an adaptable approach at each step of the thin section making process. This poster will share some of the procedural adjustments that have proven to be successful at the NASA JSC Meteorite Thin Section Laboratory. These adjustments are modifications of preparation methods that have been in use for decades and therefore do not require investment in new technology or materials.

    Full Text Available La production des oléfines légères : éthylène, propylène et butadiène est actuellement entièrement basée sur le vapocraquage d'hydrocarbures dans des fours tubulaires. L'industrie doit faire face à un problème de coûts de production croissants, en grande partie dû au renchérissement des hydrocarbures et de l'énergie. D'autres procédés que le vapocraquage ont été proposés pour favoriser la diversification sur le plan des matières premières ; certains ont même été exploités industriellement. Le présent article fait le point sur l'état des développements en cours concernant plus particulièrement les procédés suivants : - craquage autothermique ; - craquage par caloporteur solide ; - craquage cyclique ; - craquage catalytique ; - prétraitement de charges lourdes ; - oléfines à partir de gaz de synthèse ; - oléfines à partir de biomasse. The production of light olefins (ethylene, propylene and butadien is now based entirely on hydrocarbon steam cracking in pipe stills. The industry must face the problem of increasing production costs, largely due to the higher costs of hydrocarbons and energy. Processes other than steam cracking have been proposed to promote diversification with regard to raw materials, and some such processes have even operated industrially. This article sums up the state of ongoing developments concerning in particular the following processes: a autothermal cracking; b cracking by a solid heat carrier; c cyclic cracking; d catalytic cracking ; e preprocessing of heavy feeds; f olefins from synthetic gas; g olefins from biomass.

    Qiao et al. (2016) commented on our work (Zhang et al., 2014) and rejected our reinterpretation of the magnetostratigraphic results of Huang et al. (2006) and Li et al. (2006), with the results gained using the Dynamic Time Warping Algorithm technique (DTWAT) as their main basis. However, Qiao et al. (2016) did not provide details of their modeling inputs, and, in particular, the parameters they chose for their calculations, where such parameters can have a serious impact upon any results. We therefore performed calculations using the same software (i.e., Qupydon) as Qiao et al. (2016), using reliable parameter settings. The results showed that the ;interesting correlation; of a 6000 minimum cost output completely correlate with the magnetostratigraphic Chrons C18r to C3An.1n ( 40-6 Ma), which is consistent with our reinterpreted magnetostratigraphic results. Furthermore, we summarized previous biostratigraphic studies of nearby areas; the data resulting from this process also supported our reinterpreted magnetostratigraphic correlation. We were therefore able to confirm the revised magnetostratigraphic correlation of Zhang et al. (2014).

    Full Text Available Charles Bovary est probablement le personnage qui a été le plus transformé par les cinéastes qui ont adapté le roman de Flaubert. Si les premiers adaptateurs l’ont traité en victime, peu à peu, le cinéma a commencé à souligner la dimension néfaste sous-jacente du personnage et à lui faire porter une large part de responsabilité dans la descente aux enfers d’Emma. Depuis Pierre Renoir, touchant et authentique, jusqu’à Gregg Edelman, le mari de Little children qui fantasme sur les photos d’une pin-up virtuelle, en passant par les images plus ou moins pathétiques ou ridicules de Van Heflin, Aribert Wäscher, Alberto Bello, Jean-François Balmer, Farooq Shaikh ou Luis-Miguel Cintra, Charles, plus que tout autre personnage du roman, a subi une incroyable métamorphose en s’ancrant dans la civilisation de chacun des pays et de chacune des décennies successives qui l’ont porté à l’écran.From the 1930s to the present, Charles Bovary is probably the most altered character in the adaptations of Flaubert’s novel. The first directors made a victim of him, but gradually, the cinema began to emphasize his deleterious dimension and attributed to him a large part of the responsibility for Emma’s grief. From Pierre Renoir, touching and authentic, to Gregg Edelman, who fantasizes on a pornographic website in Todd Field’s Little Children, the more or less pathetic or ridiculous portrayals given by Van Heflin, Aribert Wäscher,Alberto Bello, Jean-François Balmer, Farooq Shaikh or Luis-Miguel Cintra, show that more than any other character in the novel, Charles has been submitted to a serious metamorphosis by being interpreted on screen according to each country’s civilization and the successive decades of filming.

  13. The coordination of research and innovation activities relative to an emergent technology: the case of batteries for electric and hybrid vehicles; La coordination des activites de recherche et d'innovation dans les phases d'emergence: le cas des batteries pour vehicules electriques et hybrides

    Energy Technology Data Exchange (ETDEWEB)

    Larrue, Ph.

    2000-05-23

    In this thesis, we try to provide elements of a non-deterministic view of the coordination of research activities in the phase of emergence. Firstly, we try to identify the variables that determinate the strength and the characteristics of the imperative of coordination in this very preliminary period of an innovation process. Secondly, we try to evaluate the institutional arrangements that can effectively sustain the coordination of the activities of the various interdependent actors more or less involved in the innovation process. The basic idea of the thesis is that technological innovations do not originate as isolated according to a hypothetical underlying 'nature of the technology', especially when they are controversial and subject to great uncertainties as is the case with regard to batteries for Electric and hybrid Vehicles (EVs). Innovations appear to be generated by means of the interactions of a number of organizations belonging to different 'spheres' (different industries, scientific disciplines, public institutions, etc.). In order to validate a new area of opportunity which is still very uncertain at this preliminary stage, the competences and interests of these different organizations must be coordinated. Because of the complex mix of economic and technological barriers faced by the actors taking part in this innovation process, the area of batteries for electric and hybrid vehicles is the 'perfect laboratory' to investigate the institutional arrangements that can sustain the coordination of research and innovation activities relating to an emerging technology. The empirical and theoretical investigations are mainly focused on pre-competitive research consortia such as the United-States Advanced Battery Consortium (USABC). This case study is conducted through in-depth interviews with key-actors of the area of batteries and electric vehicles. We also use the results of an on-line experts opinions survey we performed

  14. Human rights and the challenges of science and technology: Commentary on Meier et al. "Translating the human right to water and sanitation into public policy reform" and Hall et al. "The human right to water: the importance of domestic and productive water rights".

    Science.gov (United States)

    Marks, Stephen P

    2014-12-01

    The expansion of the corpus of international human rights to include the right to water and sanitation has implications both for the process of recognizing human rights and for future developments in the relationships between technology, engineering and human rights. Concerns with threats to human rights resulting from developments in science and technology were expressed in the early days of the United Nations (UN), along with the recognition of the ambitious human right of everyone "to enjoy the benefits of scientific progress and its applications." This comment explores the hypothesis that the emerging concepts most likely to follow recognition of the human right to water primarily involve issues of science and technology, such as access to medicines or clean and healthy environment. Many threats to human rights from advances in science, which were identified in the past as potential, have become real today, such as invasion of privacy from electronic recording, deprivation of health and livelihood as a result of climate change, or control over individual autonomy through advances in genetics and neuroscience. This comment concludes by urging greater engagement of scientists and engineers, in partnership with human rights specialists, in translating normative pronouncements into defining policy and planning interventions.

    2007-05-01

    Hyalinosis cutis et mucosae is a rare autosomal recessive disorder which is characterized by deposition of hyaline material around the basement membrane of the skin and mucous membranes. Typical clinical symptoms are hoarseness, infiltration of the mucous membranes and papular verrucous skin changes. Mutations within the extracellular matrix protein gene (ECM-1) are the underlying defect. We report on a 24-year-old man, who had first been seen in our department at the age of seven and had undergone the necessary diagnostic procedures and who revisited 17 years later with hoarseness and extensive verrucous skin changes at elbows and knees which were removed by excision. A new mutation of the ECM1 gene was identified.

    Full Text Available Par quelles voies les acquis cognitifs de l’expérience sont-ils mobilisés par ego dans la suite de ses actions, et sont-ils transmis à autrui ? Contrairement à la phénoménologie sociale d’Alfred Schütz dans le cadre de laquelle ces questions sont renvoyées à des processus de généralisation et de stabilisation pensés sous le prisme de la typification sociale, la théorie des fictions élaborée par Jean-Marie Schaeffer appréhende la modélisation de l’expérience vécue à partir des spécificités d’une forme proprement ludique d’expérience. Les blocages décrits par Schütz lorsqu’il envisage les situations exemplaires de l’étranger ou du soldat revenant du front y trouvent un nouvel éclairage. Proposition de mots clés :How are cognitive elements of experience available for the continuation of ego’s action, and how are they passed on to alter ? In the social phenomenology of Alfred Schutz for instance, these questions are related back to generalisation and stabilisation processes viewed through the light of social typification. On the other hand, Jean-Marie Schaeffer’s theory of fiction comprehends the modelling of some lived experiences as the fact of a specific form of ludic experience. It provides a new light on the obstructions described by Schutz considering the exemplar situations of the stranger or of the homecomer.

    2000-12-15

    The upstream oil and gas industry experienced a dramatic technological acceleration in the early 1970's. The relationships between the agents in this industry have themselves undergone deep changes since that date. This thesis shows that a tight link exists between the technological acceleration and the organizational transformations in the upstream oil and gas industry. In a first part, it focuses on the economic theory's developments concerning industrial organization. In a second part, it applies these developments to three types of relations: those between the owner-states of hydrocarbon resources and the international petroleum companies; those between the international petroleum companies and their subcontractors; and finally those between the international petroleum companies themselves.

    Ahmed, Chaara El Mouez

    Nous avons etudie les relations de dispersion et la diffusion des glueballs et des mesons dans le modele U(1)_{2+1} compact. Ce modele a ete souvent utilise comme un simple modele de la chromodynamique quantique (QCD), parce qu'il possede le confinement ainsi que les etats de glueballs. Par contre, sa structure mathematique est beaucoup plus simple que la QCD. Notre methode consiste a diagonaliser l'Hamiltonien de ce modele dans une base appropriee de graphes et sur reseau impulsion, afin de generer les relations de dispersion des glueballs et des mesons. Pour la diffusion, nous avons utilise la methode dependante du temps pour calculer la matrice S et la section efficace de diffusion des glueballs et des mesons. Les divers resultats obtenus semblent etre en accord avec les travaux anterieurs de Hakim, Alessandrini et al., Irving et al., qui eux, utilisent plutot la theorie des perturbations en couplage fort, et travaillent sur un reseau espace-temps.

    随着胜利油田水平井开采力度的进一步加大,油井含水体积分数逐年上升,层系有效开采率过低,部分层段亏空严重,已经大大降低了水平井注水在油田开发过程中所发挥的作用.为此,开展了水平井3段集成分段注水技术研究.水平井3段集成分段注水管柱主要由1级3段配水封隔器、插封注水封隔器、弹性扶正器、液压扶正器、水平井单流阀及安全接头等组成,测试仪器1次起下即可完成全井测试,投捞工具1次起下即可完成3层调配,出水通道采用防刺结构设计.现场应用结果表明,水平井分段注水技术缓解了水平井笼统注水层间矛盾,使油藏得到了合理注水开发利用,提高了注水开发效率.%With greater production efforts in horizontal wells of Shengli Oilfield,the water volume fraction in oil wells increases year by year,effective recovery rate is too low,and there occurs exhaustion in some intervals.These problems have remarkably decreased the role of water injection of horizontal well in the development of the oilfield.Therefore,research on three-section integration staged injection technology was conducted.The injection string mainly consists of three-section and one-level water regulation packer,inserting injection packer,elastic centralizer,hydraulic centralizer,horizontal check valve and safety joint.Only one trip of the tester can complete the testing of the whole well.Only one trip of the running and pulling tool can complete three-layer allocation.The water exit adopts the design of anti-puncture structure.The field application shows that the horizontal staged injection technology improves the interlayer contradiction in general injection in horizontal wells,helps oil reservoir achieve proper injection development and reduces invalid water injection.

    Full Text Available Il n’est pas inhabituel de considérer l’imagination comme une conscience d’objets non réels, ayant la forme d’images internes ou de représentations privées de toute incarnation spatiale. Dans cet article j’interroge la phénoménologie de l’imagination de Husserl à partir de deux questions : l’imagination est-elle un type de conscience d’image ? L’imagination, est-elle privée de toute incarnation spatiale ? Après avoir reconstruit la distinction nette opérée par Husserl entre imagination et conscience d’image (l’imaginaire n’est pas une image mentale interne, j’explore la thèse de Husserl, fort suggestive, selon laquelle toute imagination implique la projection du corps vécu. Loin d’être entièrement dépourvu de spatialité, l’imaginaire exhibe des caractéristiques quasi-spatiales, et il est fondé sur ce qui est « le plus propre » de mon corps vécu – cela même que, pour ainsi dire, j’amène toujours avec moi, même dans les envols les plus éloignés de mon imagination.It is not uncommon to consider the imagination as a consciousness of non-real objects in the form of internal images or representations that are bereft of spatial incarnation. In this paper, I develop Husserl's phenomenology of the imagination along two questions: Is the imagination a type of image-consciousness? Is the imagination entirely bereft of spatial incarnation? After reconstructing Husserl's trenchant decoupling of the imagination from image-consciousness  (the imaginary is not an internal mental image, I explore Husserl's suggestive thesis that the imagination involves the projection of the lived-body. Rather than consider the imaginary as entirely bereft of spatiality, the imaginary exhibits quasi-spatial characteristics, and is grounded in the "ownmost" of my lived-body, which, as it were, I always take with me, even to the farthest reaches of my imagination.

    Full Text Available Information and communications technology (ICT is integrated throughout a student’s lived experience in their post-secondary learning environment. In order for students with limited or no background with ICT to achieve their academic goals, a central part of their adaptation involves an intensive period of ICT help seeking. Using anecdotes from phenomenological research, this paper explores what we can learn about our practice as help givers through reflecting upon the lived experience of cross-cultural ICT help seeking and giving on diverse, post-secondary campuses. What surfaces from this investigation is the importance of developing an ICT support and training structure that appreciates the inter-subjective, activity-embedded nature of ICT help seeking and giving. An phenomenological educational approach to ICT help giving would be thoughtfully interwoven into a post-secondary learning environment, not as a remedial construct, but as an integral part of the learning, and help seeking, experience itself. Solliciter et fournir une aide technologique font de toute évidence partie intégrante de l’expérience étudiante, et ce, tout au long de la formation postsecondaire. Pour permettre aux étudiants avec peu ou pas d’expérience en TIC d’atteindre leurs objectifs universitaires, on doit présumer qu’une composante cruciale de leur adaptation consiste en une phase intensive de demandes d’aide technologique. À partir d’anecdotes tirées de la recherche phénoménologique, cet article explore ce que l’on peut apprendre sur nos pratiques d’assistance grâce à une réflexion sur l’expérience de demande d’aide technologique en contexte interculturel dans les institutions d’enseignement supérieur marquées par la diversité.

    2016-10-01

    Full Text Available With increased development of medical technology (MT, new challenges emerge related to education and training of pharmacists and other healthcare specialists. Currently, only a few universities in the EU promote MT education and research. Objectives: The aim of this study was to evaluate the current status, views on, and need for the education on MT for the pharmacy students and practicing pharmacists in the Baltic and Nordic countries. Methods: The representatives of higher education institutions and community/hospital pharmacists from six Baltic and Nordic countries participated in a qualitative cross-sectional exploratory internet-based study from May to October 2014. Results: Approximately two-third of the respondents considered professional knowledge about MT products important for pharmacists, but half of them had never participated in any MT courses. More practicing pharmacists than representatives of academia underlined the need for increased MT education for pharmacy students in the future. Conclusions: The pharmacists in the Baltic and Nordic countries consider the professional knowledge about MT as pertinent in their education and work. The limited number and status of MT courses available today, however, is a major concern among both pharmacy students and practicing pharmacists in these countries. In the future, increasing education combining theory and practice about MT products would be one possible solution to overcome this challenge.

  11. Comprendre le processus d'adaptation des demarches d'enseignement en classe de sciences et technologies a l'ecole secondaire: Analyse des besoins percus par les personnes enseignantes en milieu defavorise

    Houde, Sylvie

    Since the implementation of the latest reform in the education programs of Quebec, the adaptation of teaching has taken on an important place in the concerns of all actors in education. However, this adjustment towards the adoption of teaching practices that require more participation on the part of the pupil is not accomplished so easily, particularly in the field of science and technology (ST). In order to gain a better understanding of these processes of adaptation, it is opportune to question ourselves on the factors and dynamics of interest at stake, especially in disadvantaged environments. Such environments are faced with situations where other difficulties coexist: integration of pupils, lack of interest, problems in classroom management, multi-ethnicity, etc. As a result, such difficulties give rise to particular limitations, expressed in the form of needs, by pupils and teachers, likely to have a restrictive effect on the adaptation of teaching practices. Accordingly, our research focuses on the needs perceived by teachers in high school ST classrooms in disadvantaged school environments, since they present a privileged means to better understand the processes involved in the adaptation of practices. The adoption of an ecosystemic perspective, centered on these needs and their contribution towards the dynamics of decision-making, enabled us to better apprehend the complexity of these processes in ST classrooms. We were able to identify the needs perceived by teachers by following the methodology of conceptanalysis of needs, and by combining focus groups with the DRAP software. The results account for the large variety of needs to be considered in the equation of adaptation of teaching practices. These needs generally belong to the classroom system (microsystem). For pupils, they are mainly cognitive needs, but for teachers, they pertain to organization and structure. The influence of these needs on the adaptation processes depends on the interpretation by

    Full Text Available L’article est une exploration systématique de la dualité des figures du Mind et du Geist, le premier étant entendu comme l’esprit en tant que partie de la nature scientifiquement objectivable, le second comme l’esprit en tant qu’acteur immatériel insaisissable de la pensée. De plus, cette dualité est étudiée du point de vue de l’interférence de la mathématique avec elle, dans plusieurs contextes. Sont ainsi successivement analysés : le conflit entre les deux « modèles » du Mind, le computationnaliste et le dynamiciste; la définition philosophique et la définition épistémologique du Geist ; le jeu entre Mind et Geist dans les recherches cognitives contemporaines ; l’ambivalence de la logique et des mathématiques vis-à-vis de l’opposition Mind/Geist. Dans la partie finale, on propose une définition personnelle du Geist–en termes d’adresse et de sujet–dont dérive une détermination du Mind. Revenant sur ces nouvelles bases à l’interférence avec la mathématique, on conclut sur la question essentielle et délicate de la paramétrisation de la conscience.This paper systematically investigates the conflicting figures of Mind and Geist : Mind has to be understood as some part of nature likely to become the object of science, while Geist names the unmaterial unseizable protagonist of thought. Further, the opposition of the two figures is studied in the light of the way mathematics interfere with it, in several contexts. This leads to following analyses : how computational and dynamicist models of Mind compete within cognitive science; how Geist may be defined philosophically and epistemologically ; how Mind and Geist differently come to be considered or to be aimed at within contemporary cognitive research ; how mathematics and logic play an ambivalent part with respect to the Mind/Geist opposition. In the final section of the paper, a personal definition of the Geist–in terms of address and

    Following Chernobyl accident which has revealed in France a strong need for information on technological risks among population and a lack in its organization, the Mayor of Grenoble City who was also at this time, Environment Minister in French Government had initiated in lsere Region an important operation of consideration of action, which has to been undertaken to correct theses lacks. Among ten actions retained one of them was the creation of an Association for Information of the public for Prevention of major risks. This Association has first initiated a consultation on the perception by the population of the different major risks (Industrial and Naturals) in view of the results of this consultation, Medical Professions were the first concerned and a publication 'Medicine and Nuclear risk' has been elaborated and distributed to all doctors of the Region. A Memento on Nuclear risk as then been written and largely distributed in the region, especially in the medias. A booklet on nuclear risk and behavior in case of nuclear accident has then been realized and distributed to all people around Electronuclear Reactors of the Region and to children in the schools. In complement, public meetings have been organized in these sectors to inform, and discuss with the population. (author)

    Injectors for space rockets engines have been realised an tested at ONERA. Thanks to an original manufacturing technique, they allow one to get pulverization characteristics superior than those obtained with classic injectors. This improvement increases performances, allows a reduction of the size and mass of combustion chambers, while reducing manufacturing costs in the case of small series. These injectors are constituted by very thin plates fabricated by standard or chemical means. Individual plates are then assembled together by diffusion bond or brazing. This mode of fabrication allows one to conceive hydraulic circuits which would be impossible to realize with conventional metal machining. This technique, developed since the 70's in the United States by the AEROJET Company for the fabrication of platelets, complete combustion chambers and heat exchangers, has been adopted at ONERA for developing injectors at the request of CNES. An injector of this type, used at ONERA as a test tool on a very hot air generator, has given complete satisfaction. The industrial development of this technique will necessitate to achieve a technological step at the design level and to improve French capabilities in the diffusion bond process for materials others that titanium, such as stainless steel.

    To report long-term outcomes of laparoscopic radical cystectomy (LRC) in a multicentre European cohort, and explore feasibility and safety of LRC. This study was coordinated by European Association of Urology (EAU)-section of Uro-technology (ESUT) with nine centres enrolling 503 patients undergoing LRC for bladder cancer prospectively between 2000 and 2013. Data were retrospectively analysed. Descriptive statistics were used to explore peri- and postoperative characteristics of th ecohort. Kaplan-Meier curves were constructed to evaluate recurrence-free survival (RFS), cancer-specific survival (CSS) and overall survival (OS). Outcomes were also stratified according to tumour stage, lymph node (LN) involvement and surgical margin status. Minor complications (Clavien I-II) occurred in 39% and major (IIIa-IVb) in 17%. In all, 10 (2%) postoperative deaths were recorded. The median (interquartile, IQR) LN retrieval was 14 (9-17) and positive surgical margins were detected in 29 (5.8%) patients. The median (mean, IQR) follow-up was 50 (60, 19-90), during which 134 (27%) recurrences were detected. Actuarial RFS, CSS and OS rates were 66%, 75% and 62% at 5 years and 62%, 55%, 38% at 10 years. Significant differences in RFS, CSS and OS were found according to tumour stage, LN involvement and margin status (log-rank P < 0.001). On multivariate Cox analysis, T stage and LN involvement (both P < 0.001) were significant predictors of RFS, CSS and OS. Positive margins were significant predictors of RFS (P = 0.016) and CSS (P = 0.043). In this European LRC multicentre study, the largest to date, long-term RFS, CSS and OS rates after LRC appear comparable to those reported in current open RC series. Further randomised controlled trials are necessary to assess the global impact of LRC. © 2014 The Authors. BJU International © 2014 BJU International.

    Projects dealing with future reactors consider using new fuels and demonstrate the ability of such reactors to incinerate nuclear waste. These projects have triggered new interest in cross section measurements for a large number of elements over a wide energy range. In some cases, existing data bases disagree, making new measurements necessary. Complete high resolution cross section measurements require both large beam times, and large data analysis times. However, a good capture cross section profile between 0.1 eV and 30 keV can be obtained using a lead slowing down time spectrometer in association with a pulsed neutron generator. Such measurements have been performed at the Institut des Sciences Nucleaires (ISN) at Grenoble. The neutron flux is measured with a {sup 233}U fission detector and an {sup 3}He gas detector and the results are compared to very precise Monte Carlo simulations (MCNP code) of the experimental set up, using several data bases for lead. We have shown that, with this method, the scattering cross section on lead can be tested with a precision of the order of 1.5%. Capture rates, measured with a CeF{sub 3} scintillator coupled to a photomultiplier, are compared to simulation results using different data bases for the samples. Reference materials (Au, Ag, In, Ta) have been measured, materials that are present in the core of reactors ({sup 232}Th, U, {sup 99}Tc) have been tested, as well as structure materials (W, Mo, Ni, Mn). Data bases are validated with a precision of 5%. Measurements done for different target thicknesses complete the data. Areas of agreement and disagreement between experimental results and data bases are systematically described. Finally, a correction table for the capture cross sections extracted from the appropriate data base is obtained and presented, for some elements. (author)

    Full Text Available Although saliva endothelins are emerging as valuable noninvasive cardiovascular biomarkers, reports on the relationship between isoforms in saliva and plasma remain scarce. We measured endothelins in concurrent saliva and plasma samples (n=30 males; age 18–63 by HPLC-fluorescence. Results revealed statistically significant positive correlations among all isoforms between saliva and plasma: big endothelin-1 (BET-1, 0.55 ± 0.27 versus 3.35 ± 1.28 pmol/mL; r=0.38, p=0.041, endothelin-1 (ET-1, 0.52 ± 0.21 versus 3.45 ± 1.28 pmol/mL; r=0.53, p=0.003, endothelin-2 (ET-2, 0.21 ± 0.07 versus 1.63 ± 0.66 pmol/mL; r=0.51, p=0.004, and endothelin-3 (ET-3, 0.39 ± 0.19 versus 2.32 ± 1.44 pmol/mL; r=0.75, p<0.001. Correlations of BET-1, ET-1, and ET-3 within each compartment were positive in both plasma (p<0.05 and saliva (p≤0.1, whereas ET-2 was not significantly correlated with other isoforms in either plasma or saliva. For all isoforms, concentrations varied on average fivefold between individuals (90th/10th percentiles; individuals with high plasma endothelin levels generally had high saliva endothelin levels. Our results reveal that salivary ET isoform profiles portray the plasmatic profiles and support the view of coordinated regulation of ET-1 and ET-3, but distinct regulatory pathways for ET-2.

    Full Text Available Backchannel technology can be used to allow students in large lecture courses to communicate with each other and the instructor during the delivery of lecture content and class discussions. It can also be utilized by instructors to capture, summarize, and integrate student questions, ideas, and needs into course content both immediately and throughout the course. The authors integrated backchannel software in one of two sections of a course, leaving the other section as a control; combined, the two sections contained a total number of 871 students. Data was gathered comparing both groups using online surveys and semester grades; results showed that the section using backchannel software had higher class satisfaction and perception of engagement, used their mobile devices more for accessing class content, felt more comfortable participating in class discussions, and had a higher grade average than the section that did not. The authors also explore their own experiences of finding, integrating, and maintaining backchannel technology. La technologie d’arrière-plan peut permettre aux étudiants de grands cours magistraux de communiquer les uns avec les autres et avec l’instructeur durant le cours et les discussions en classe. Les instructeurs peuvent aussi l’utiliser pour saisir, résumer et intégrer les questions, idées et besoins des étudiants dans le contenu du cours, et ce, immédiatement et pendant toute la durée du cours. Les auteurs ont intégré un logiciel d’arrière-plan dans l’une des deux sections d’un cours, faisant de l’autre section son groupe témoin. Ensemble, les deux sections comprenaient 871 étudiants. Des données ont été recueillies pour comparer les deux groupes à l’aide de sondages en ligne et des notes du trimestre. Les résultats ont démontré que la section utilisant le logiciel d’arrière-plan avait une plus grande satisfaction et une meilleure perception de l’engagement, que ses

    Over the years this conference has gained a solid reputation as an appropriate rostrum for illustrating new concepts in the relations between industry and the scientific world and for introducing new technologies to a large assistance of junior and more experienced scientists. In fact, from the very beginning the founders of this endeavour announced: "The conference is aimed for promoting contacts among scientists involved in particle and fundamental physics, among experimental physicists in other fields and representatives from industry." Facilities at the Conference are designed to fulfil the task: space and general facilities are offered to industry representatives to display their products. This year a more accessible and luminous space arrangement was made available to the exhibitors. At the same time two plenary sessions have been dedicated to selected speakers to illustrate new trends in Technology Transfer, analysis of environment affecting our community, examples of historical successes in the merging of science and industry. We have identified in "GRID" and in "E-Publishing" two major promising areas where our Community will play a prime role as "User" and it was of the general interest to have them illustrated by two personalities directly involved in their development. The flow of knowledge is of course more massive from "Industry" to "Science" than vice-versa, but "Science" to "Industry" move offers an intensive added value. The technology transfer concept with the "Patents" as fund raising tool proved less glorious than expected. Trademark, licensing agreement and " Patents" can assure intellectual properties. But patent is an issue to be used cautiously. Evidence exists that much more efficient transfer of "Science" knowledge to "Economy" is achieved by venture capital move and start-up companies. These two facets of the Technology Transfer business have been covered by Routti's and Bourgeois's lectures.There are two examples of Companies who moved

  18. Theories and calculation methods for regional objective ET

    Institute of Scientific and Technical Information of China (English)

    2009-01-01

    The regional objective ET (Evapotranspiration) is a new concept in water resources research, which refers to the total amount of water that could be exhausted from a region in the form of vapor per year. The objective-ET based water resources management allocates water to different regions in terms of ET. It controls the water exhausted from a region to meet the objective ET. The regional objective ET must be adapted to fit the region's local available water resources. By improving the water utilization effi-ciency and reducing the unrecoverable water in the social water circle, it is saved so that water related production is maintained or even increased under the same water consumption conditions. Regional water balance is realized by rationally deploying the available water among different industries, adjusting industrial structures, and adopting new water-saving technologies, therefore to meeting the requirements for groundwater conservation, agricultural income stability, and avoiding environmental damages. Furthermore, water competition among various departments and industries (including envi-ronmental and ecological water use) may be avoided. This paper proposes an innovative definition of objective ET, and its principles, sub-index systems. Besides, a computational method for regional ob-jective ET is developed by combining the distributed hydrological model and the soil moisture model.

    The aim of this study was to investigate the usefulness of ethyl glucuronide (EtG) and ethyl sulfate (EtS) as biomarkers of the hangover state. Thirty-sixhealthy social drinkers participated in this study, being of naturalistic design. Eighteen participants experience regular hangovers (the hangover group), whereas the other 18 claim to not experience a hangover (the hangover-immune group). On a control day (alcohol-free) day and a post-alcohol day, urine EtG and EtS concentrations were determined and hangover severity assessed. Urinary EtG and EtS concentrations were significantly increased on post-alcohol day compared to the control day (p = .0001). Both EtG and EtS concentrations did not significantly correlate with the overall hangover score, nor with the estimated peak blood alcohol concentrations and number of alcoholic drinks. EtG correlated significantly only with the individual hangover symptom "headache" (p = .033; r = .403). No significant correlations were found with the EtG to EtS ratio. EtG and EtS concentrations significantly correlated with urine ethanol concentrations. Although urine EtG and EtS concentration did not significantly correlate to estimated peak blood alcohol concentrations or the number of alcoholic drinks consumed, a significant correlation was found with urine ethanol concentration. However, urine EtG and EtS concentrations did not significantly correlate with overall hangover severity. © 2017 The Authors.

  1. Technology '90

    Energy Technology Data Exchange (ETDEWEB)

    1991-01-01

    The US Department of Energy (DOE) laboratories have a long history of excellence in performing research and development in a number of areas, including the basic sciences, applied-energy technology, and weapons-related technology. Although technology transfer has always been an element of DOE and laboratory activities, it has received increasing emphasis in recent years as US industrial competitiveness has eroded and efforts have increased to better utilize the research and development resources the laboratories provide. This document, Technology '90, is the latest in a series that is intended to communicate some of the many opportunities available for US industry and universities to work with the DOE and its laboratories in the vital activity of improving technology transfer to meet national needs. Technology '90 is divided into three sections: Overview, Technologies, and Laboratories. The Overview section describes the activities and accomplishments of the DOE research and development program offices. The Technologies section provides descriptions of new technologies developed at the DOE laboratories. The Laboratories section presents information on the missions, programs, and facilities of each laboratory, along with a name and telephone number of a technology transfer contact for additional information. Separate papers were prepared for appropriate sections of this report.

  4. Special section on biomimetics of movement.

    Carpi, Federico; Erb, Rainer; Jeronimidis, George

    2011-12-01

    Movement in biology is an essential aspect of survival for many organisms, animals and plants. Implementing movement efficiently to meet specific needs is a key attribute of natural living systems, and can provide ideas for man-made developments. If we had to find a subtitle able to essentially convey the aim of this special section, it could read as follows: 'taking inspiration from nature for new materials, actuators, structures and controls for systems that move'. Our world is characterized by a huge variety of technical, engineering systems that move. They surround us in countless products that integrate actuators for different kinds of purposes. Basically, any kind of mechatronic system, such as those used for consumer products, machines, vehicles, industrial systems, robots, etc, is based on one or more devices that move, according to different implementations and motion ranges, often in response to external and internal stimuli. Despite this, technical solutions to develop systems that move do not evolve very quickly as they rely on traditional and well consolidated actuation technologies, which are implemented according to known architectures and with established materials. This fact limits our capability to overcome challenges related to the needs continuously raised by new fields of application, either at small or at large scales. Biomimetics-based approaches may provide innovative thinking and technologies in the field, taking inspiration from nature for smart and effective solutions. In an effort to disseminate current advances in this field, this special section collects some papers that cover different topics. A brief synopsis of the content of each contribution is presented below. The first paper, by Lienhard et al [1], deals with bioinspiration for the realization of structural parts in systems that passively move. It presents a bioinspired hingeless flapping mechanism, considered as a solution to the kinematics of deployable systems for

    Three satellite communication projects now in progress in Japan are described. The first is a project to establish a telecommunication network for tele-education, TV conference, and tele-medicine in the Asia-Pacific region by using the Japan's Engineering Test Satellite-5 (ETS-5). The second is a project of the ETS-6 satellite, to be launched in 1993, for inter-satellite communication, mobile and fixed communication, and millimeter wave personal communication experiments. The third is a project of the Communications and Broadcasting Engineering Test Satellite (COMETS), to be launched in 1997, for advanced mobile satellite communication, inter-satellite link, and advanced broadcasting experiments at higher frequencies.

  8. Fabrication Technology

    1993-03-01

    The mission of the Fabrication Technology thrust area is to have an adequate base of manufacturing technology, not necessarily resident at Lawrence Livermore National Laboratory (LLNL), to conduct the future business of LLNL. The specific goals continue to be to (1) develop an understanding of fundamental fabrication processes; (2) construct general purpose process models that will have wide applicability; (3) document findings and models in journals; (4) transfer technology to LLNL programs, industry, and colleagues; and (5) develop continuing relationships with the industrial and academic communities to advance the collective understanding of fabrication processes. The strategy to ensure success is changing. For technologies in which they are expert and which will continue to be of future importance to LLNL, they can often attract outside resources both to maintain their expertise by applying it to a specific problem and to help fund further development. A popular vehicle to fund such work is the Cooperative Research and Development Agreement with industry. For technologies needing development because of their future critical importance and in which they are not expert, they use internal funding sources. These latter are the topics of the thrust area. Three FY-92 funded projects are discussed in this section. Each project clearly moves the Fabrication Technology thrust area towards the goals outlined above. They have also continued their membership in the North Carolina State University Precision Engineering Center, a multidisciplinary research and graduate program established to provide the new technologies needed by high-technology institutions in the US. As members, they have access to and use of the results of their research projects, many of which parallel the precision engineering efforts at LLNL.

    La relativité générale a cessé d'être une pure théorie justifiée par les "trois tests classiques" disponibles il y a trente ans. Des pulsars, vrais laboratoires de gravitation relativiste, ont été découverts et étudiés. A l'automne 1991 les Etats-Unis ont pris la décision de construire deux détecteurs interférométriques d'ondes gravitationnelles. Au début de l'été 1992, le ministre français de la Recherche et de l'Espace a pris un engagement de même nature concernant le projet VIRGO, projet franco-italien de construction d'une antenne interférométrique. La gravitation relativiste est devenue un riche domaine d'observation et d'expérimentation. Cet ouvrage est un manuel de physique dont les intentions et le contenu se veulent adaptés au contexte scientifique actuel. Il doit beaucoup aux divers enseignements donnés par l'auteur, principalement l'enseignement de relativité générale en maîtrise de physique à l'université Pierre et Marie Curie (Paris VI). Dans la première partie, l...

    La radioactivité de l’environnement autour de l’Organisation Européenne pour la Recherche Nucléaire (CERN) et les doses de rayonnements qui en résultent pour la population avoisinante sont contrôlées par la Commission de Sécurité du CERN et de manière indépendante par les autorités compétentes des deux États Hôtes, l’Institut de Radioprotection et de Sûreté Nucléaire (IRSN) côté France et l’Office Fédéral de la Santé Publique (OFSP) côté Suisse (voire Chapitre 8.6). Dans ce rapport, les résultats de mesures concernent en particulier le territoire suisse. L’ensemble des mesures effectuées en 2006 prouve que le fonctionnement des installations du CERN était sans conséquence radiologique sur l’environnement et la population. Le contrôle des émissions montre que les rejets effectifs se situent, également en 2006, nettement en dessous des limites réglementaires. Ce constat est confirmé par le contrôle des immissions dans l’environnement. Le CERN a bien respecté en 2...

    The Thorium cycle Th{sup 232}/U{sup 233} may face brilliant perspectives through advanced concepts like molten salt reactors or accelerator driven systems but it lacks accurate nuclear data concerning some nuclei. Pa{sup 233} is one of these nuclei, its high activity makes the direct measurement of its radiative neutron capture cross-section almost impossible. This difficulty has been evaded by considering the transfer reaction Th{sup 232}(He{sup 3},p)Pa{sup 234}* in which the Pa{sup 234} nucleus is produced in various excited states according to the amount of energy available in the reaction. The first chapter deals with the thorium cycle and its assets to contribute to the quenching of the fast growing world energy demand. The second chapter gives a detailed description of the experimental setting. A scintillation detector based on deuterated benzene (C{sub 6}D{sub 6}) has been used to counter gamma ray cascades. The third chapter is dedicated to data analysis. In the last chapter we compare our experimental results with ENDF and JENDL data and with computed values from 2 statistical models in the 0-1 MeV neutron energy range. Our results disagree clearly with evaluated data: our values are always above ENDF and JENDL data but tend to near computed values. We have also perform the measurement of the radiative neutron cross-section of Pa{sup 231} for a 110 keV neutron: {sigma}(n,{gamma}) 2.00 {+-} 0.14 barn. (A.C.)

    Les philosophies de Nietzsche et Deleuze ont en commun que la pensée, comme la vie qu’elle recèle, n’est que mouvements. Mouvements rapides et hétérogènes parcourant les surfaces, comprenant l’être lui-même comme surface à traverser. Mouvements et surface organisent un jeu, celui de la pensée. Ce jeu, que Deleuze appellera « le jeu idéal », est à comparer par ses spécificités aux sports.

    Ets-2 is a ubiquitous transcription factor activated after phosphorylation at threonine-72. Previous studies highlighted the importance of phosphorylated ets-2 in lung inflammation and extracellular matrix remodeling, two pathways involved in pulmonary fibrosis. We hypothesized that phosphorylated ets-2 played an important role in pulmonary fibrosis, and we sought to determine the role of ets-2 in its pathogenesis. We challenged ets-2 (A72/A72) transgenic mice (harboring a mutated form of ets-2 at phosphorylation site threonine-72) and ets-2 (wild-type/wild-type [WT/WT]) control mice with sequential intraperitoneal injections of bleomycin, followed by quantitative measurements of lung fibrosis and inflammation and primary cell in vitro assays. Concentrations of phosphorylated ets-2 were detected via the single and dual immunohistochemical staining of murine lungs and lung sections from patients with idiopathic pulmonary fibrosis. Ets-2 (A72/A72) mice were protected from bleomycin-induced pulmonary fibrosis, compared with ets-2 (WT/WT) mice. This protection was characterized by decreased lung pathological abnormalities and the fibrotic gene expression of Type I collagen, Type III collagen, α–smooth muscle actin, and connective tissue growth factor. Immunohistochemical staining of lung sections from bleomycin-treated ets-2 (WT/WT) mice and from patients with idiopathic pulmonary fibrosis demonstrated increased staining of phosphorylated ets-2 that colocalized with Type I collagen expression and to fibroblastic foci. Lastly, primary lung fibroblasts from ets-2 (A72/A72) mice exhibited decreased expression of Type I collagen in response to stimulation with TGF-β, compared with fibroblasts from ets-2 (WT/WT) mice. These data indicate the importance of phosphorylated ets-2 in the pathogenesis of pulmonary fibrosis through the expression of Type I collagen and (myo)fibroblast activation. PMID:21562315

L’État tunisien a arbitré entre différents intérêts professionnels en fonction des nécessités de la pérennisation du régime autoritaire. Les rapports de force politique entre les différents acteurs, i.e. les gouvernants, le barreau, les experts comptables et les autres professions du chiffre, ont contribué au découpage d’un territoire professionnel perçu comme défavorable par des avocats eux-mêmes appréhendés par le pouvoir comme une profession dangereuse.

    Full Text Available Loin de la fascination qu’exerce la chute, promesse de renouveau pour Baudelaire et de plaisir pour Adorno, le funambule fait quotidiennement l’expérience d’une prise et d’une maîtrise du risque. Faisant du risque un spectacle, le funambule évolue sur un fil, nous renvoyant aux premières sensations de la marche, mal assurée, hésitante et tellement audacieuse. Le funambule travaillant au quotidien son équilibre se doit donc de prendre des risques, mais aussi de donner l’illusion d’une première fois : simuler le danger là où il est pourtant. C’est en jouant sur le moment de la rupture, de la chute que le funambule capte l’attention. Il donne un corps à cette question de la limite et semble nous proposer une adaptation douce au risque, là où le dompteur parait s’y opposer plus frontalement.

    2001-12-01

    Today, high voltage overhead power lines are badly perceived by the population in particular in urban areas and in areas with remarkable landscapes, for their visual impact on the environment and for their possible effect on human health. With the increase of the domestic and foreign power demand, the high voltage grid will develop in the future and the partial burial of power lines can be the first steps towards a solution to these problems. This report makes a worldwide status of the state-of-the-art of power line burial technologies, all voltages considered, and then focusses on the very-high voltage challenge which encounters the most important technological and economical constraints. The technical feasibility has been proven but the lowering of costs needs the development of a real European market of power lines burial. (J.S.)

    Currently, the essential part of the money invested by the industrialist is for the water treatment. In France, most of the 20 billions francs per year devoted to the water treatment is used for the industrial activity. The global management of effluents favour the integration of clean technologies (optimization, change and modification of the production process) in order to reduce the pollution problem at its source. Our study aims at the introduction of clean technologies in the metal workshops (consumer and generator of water and chemicals) by the development of two data management methods, which lead to two decision support systems. The aim of the first one is to minimize both the water consumption and the wastewater disposal by optimizing the production process (optimum yield and efficiency of the rinsing baths). The second one concerns the choice of valorization techniques considering the valorization objectives, the effluents characteristics and the parameters limiting the use of the techniques. Our approach fits into a global management method for the metal finishing industry wastewater. Its aim is to limit the quantity of wastewater generated, to valorize effluents and by this way to develop the clean technologies.

  3. Figures mythiques et histoire. Réinterprétations et contrastes entre Orient et Occident

    2009-05-01

    Full Text Available L'histoire de l'Orient musulman est jalonnée de grands personnages qui servent de modèles de référence et d'ancêtres fondateurs, certains hérités de l'islam, d'autres de l'Antiquité et de la Bible. Leur figure s'est transformée en Orient musulman à partir du Xe siècle, largement sous l'influence du Shâh-nâma, quand se sont multipliées les dynasties indépendantes, puis à la suite de l'irruption des Turcs, des Croisés et des Mongols. Les exemples de Saladin et de Gengis Khan illustrent le renouvellement des modèles, leur extension et leurs réinterprétations successives. La créativité mythique apparaît comme un acte culturel, de portée éminemment politique. La carrière d'un grand conquérant comme Tamerlan a servi de modèle à ses épigones pour justifier leurs prétentions territoriales. Les références bibliques attestées dans le Coran ont permis d'intégrer les Turcs, puis les Mongols, dans l'histoire de la Création, comme descendants de l'un des trois fils de Noé. Des rattachements bibliques anciens ont valorisé les musulmans des régions de la Volga à partir du XVIIIe siècle, ainsi que les différents peuples chrétiens et musulmans du Caucase, région riche en références bibliques comme l'échouage de l'arche de Noé sur le mont Ararat et l'enfermement des peuples de Gog et Magog derrière des portes de fer.

    Producing nuclear energy in order to reduce anthropic CO{sub 2} emission and to meet high energy demand, implies three conditions to the nuclear plants of the IV. generation: safety improvements, radioactive waste minimization, and fuel breeding for a sustainable use of the resources. The Thorium fuel cycle used in Molten Salt Reactors seems promising. Many numerical studies based on probabilistic codes are carried out in order to analyse the behaviour of such reactors. Nevertheless, one of the most important parameters is badly known: the alpha ratio of {sup 233}U, ratio of the neutron capture cross section to fission one for {sup 233}U. This key-parameter is necessary to calculate the breeding ratio and thus, the deployment capacities of those reactors. This Ph-D thesis was intended to prepare a precise measurement of the alpha ratio of {sup 233}U between 1 eV and 10 keV. Preliminary measurements have been performed on the experimental platform PEREN. This experimental environment is composed of a lead slowing-down time spectrometer associated with an intense pulsed neutron generator. Capture and fission rates are measured thanks to eight scintillators with their photomultipliers, surrounding a fission chamber. A software analysis sets the coincidence rate between the scintillators. In order to understand perfectly the experimental setup, preliminary tests using a {sup 235}U fission chamber have been done. This experiment resulted in a very low signal to background ratio (1 %). The background coming from the scintillators themselves seriously handicapped the measurement. Another series of experiment has been done with scintillators 5 times thinner. Nevertheless, the signal to background ratio should still be increased to measure the capture of {sup 235}U. To make sure that the experimental setup has totally been understood, we made many comparisons between experimental results and simulations. Two simulation codes were mainly used: MCNP and GEANT4.

    Ce livre reproduit un cours inédit de Louis de Broglie, de 1948, dans lequel il réexamine, gráce à la relativité, les analogies entre la mécanique et la thermodynamique étudiés par Helmholtz, Boltzmann et Planck avant le succès de la mécanique statistique. C'est le premier d'une série de travaux de de Broglie en vue de prolonger sa découverte de 1924 vers une mécanique ondulatoire des processus irréversibles, en unifiant les principes de Fermat, de Maupertuis et de Carnot-Clausius. L'intérêt du livre est triple: 1. une généralisation de la mécanique quantique qui décrirait les transitions quantiques en tant que processus dynamiques; 2. revisiter la physique classique en compagnie de l'un des plus grands physiciens du siècle 3. découvrir quelques grands idées oubliées de la physique classique.

    The Energy Technology Division provides materials and engineering technology support to a wide range of programs important to the US Department of Energy. As shown on the preceding page, the Division is organized into ten sections, five with concentrations in the materials area and five in engineering technology. Materials expertise includes fabrication, mechanical properties, corrosion, friction and lubrication, and irradiation effects. Our major engineering strengths are in heat and mass flow, sensors and instrumentation, nondestructive testing, transportation, and electromechanics and superconductivity applications. The Division Safety Coordinator, Environmental Compliance Officers, Quality Assurance Representative, Financial Administrator, and Communication Coordinator report directly to the Division Director. The Division Director is personally responsible for cultural diversity and is a member of the Laboratory-wide Cultural Diversity Advisory Committee. The Division's capabilities are generally applied to issues associated with energy production, transportation, utilization or conservation, or with environmental issues linked to energy. As shown in the organization chart on the next page, the Division reports administratively to the Associate Laboratory Director (ALD) for Energy and Environmental Science and Technology (EEST) through the General Manager for Environmental and Industrial Technologies. While most of our programs are under the purview of the EEST ALD, we also have had programs funded under every one of the ALDs. Some of our research in superconductivity is funded through the Physical Research Program ALD. We also continue to work on a number of nuclear-energy-related programs under the ALD for Engineering Research. Detailed descriptions of our programs on a section-by-section basis are provided in the remainder of this book. This Overview highlights some major trends.

    Full Text Available Sur la base de deux événements d’inondation ayant touché récemment, dans des contextes politiques, organisationnels et hydrologiques bien différents, de nouveaux quartiers d’habitation, cet article rend compte des pratiques des acteurs impliqués dans des situations d’alerte et de crise en Suisse. Le recensement des acteurs – à travers leur rôle et leur place dans les mécanismes de préparation, d’alerte et de gestion –, ainsi que l’inventaire des documents mobilisés par ceux-ci, ont été réalisés dans les deux cas. Cette analyse a permis d’évaluer la gestion des événements, de déceler les changements organisationnels qui ont suivi les crises et de connaître la conception et le degré de formalisation du risque dont étaient dotés les différents acteurs avant et après les inondations. Plus encore, l’analyse a documenté les nouveaux processus d’alerte et de prévision qui ont été mis en place suite aux événements. Il s’avère ainsi que les épisodes d’inondation agissent de façon décisive sur la production de connaissances, à un degré variable selon les acteurs. Ces épisodes révèlent aussi parfois l’existence de connaissances « en attente » qui ne sont pas encore intégrées dans les procédures institutionnelles. Tant du point de vue de la prévision que de la gestion de la crise, ils permettent aussi de tester les canaux de l’information et de combler les déficits d’organisation, de collaboration et de sécurisation des dispositifs de communication. En outre, les risques et les crises liés aux inondations modifient les dynamiques et les politiques territoriales, conséquences du réajustement des réseaux d’acteurs. La mise en place de dispositifs d’intervention et de gestion de crise se montre cependant plus efficace que la refonte des dispositifs d’aménagement, généralement longue.

    Molecular stratification of prostate cancer (PCa) based on genetic aberrations including ETS or RAF gene-rearrangements, PTEN deletion, and SPINK1 over-expression show clear prognostic and diagnostic utility. Gene rearrangements involving ETS transcription factors are frequent pathogenetic somatic events observed in PCa. Incidence of ETS rearrangements in Caucasian PCa patients has been reported, however, occurrence in Indian population is largely unknown. The aim of this study was to determine the prevalence of the ETS and RAF kinase gene rearrangements, SPINK1 over-expression, and PTEN deletion in this cohort. In this multi-center study, formalin-fixed paraffin embedded (FFPE) PCa specimens (n = 121) were procured from four major medical institutions in India. The tissues were sectioned and molecular profiling was done using immunohistochemistry (IHC), RNA in situ hybridization (RNA-ISH) and/or fluorescence in situ hybridization (FISH). ERG over-expression was detected in 48.9% (46/94) PCa specimens by IHC, which was confirmed in a subset of cases by FISH. Among other ETS family members, while ETV1 transcript was detected in one case by RNA-ISH, no alteration in ETV4 was observed. SPINK1 over-expression was observed in 12.5% (12/96) and PTEN deletion in 21.52% (17/79) of the total PCa cases. Interestingly, PTEN deletion was found in 30% of the ERG-positive cases (P = 0.017) but in only one case with SPINK1 over-expression (P = 0.67). BRAF and RAF1 gene rearrangements were detected in ∼1% and ∼4.5% of the PCa cases, respectively. This is the first report on comprehensive molecular profiling of the major spectrum of the causal aberrations in Indian men with PCa. Our findings suggest that ETS gene rearrangement and SPINK1 over-expression patterns in North Indian population largely resembled those observed in Caucasian population but differed from Japanese and Chinese PCa patients. The molecular profiling data presented in this study could help in

    Full Text Available Malgré son inactualité apparente, La Tentation de Saint Antoine se rattache à une série de savoirs, de recherches historiques, d’interrogations qui caractérisent son époque et définissent une configuration épistémologique. Les savoirs sont impliqués à deux niveaux : dans l’organisation de la poétique de l’œuvre, dans les représentations de l’œuvre. Flaubert utilise des savoirs historiques, anthropologiques et psychiatriques qui légitiment l’organisation du texte et les déconstruit en même temps. Il invente une nouvelle forme de grotesque – le grotesque des idées – et met en abyme un questionnement sur les savoirs qui évolue de la première Tentation à celle de 1874.Despite its apparent irrelevancy to Flaubert's time, La Tentation de Saint Antoine is linked to a net of knowledge, historical research, questions that characterize a period and define an epistemological configuration. These types of knowledge are at play on two levels: in the organization of the poetics of the work and in its representations. Flaubert uses historical, anthropological and psychiatric knowledge which legitimates the organization of the text while at the same time he deconstructs this body of knowledge. Flaubert invents a new form of grotesque – the grotesque of ideas – and, in a mise-en-abyme from the first Tentation to the 1874 version, he questions these fields of knowledge.

    During offshore wind turbine foundation construction,the transition section tower installation and leveling are the key and difficulty. Complex and bad construction conditions on the sea,it is quite difficult to realize precise installation and accurate leveling of the transition section tower. And the current domestic offshore wind turbine transition section tower installation is not mature. During a 5 M W wind turbine construction in Shanghai east China offshore wind farm, researching of transition section tower making process,installation procedures, leveling technique and the measures taken to prevent deformation, combining with the engineering practice, the difficulties lie in the precise installation and accurate leveling of the transition section tower on the sea are solved.%在海上风电场风机基础施工过程中,过渡段塔筒安装及调平是重点和难点.在海上复杂、恶劣的施工条件下,要实现过渡段塔筒的精确安装与精准调平具有相当大的难度,目前国内海上风机过渡段塔筒的安装技术还未成熟.文章以上海东海风电场5 MW大容量样机为例,通过研究过渡段塔筒加工制作过程、安装工序、调平工艺以及施工过程中预防变形所采取的措施等,结合工程实际,解决了在海上进行风机过渡段塔筒精确安装与精准调平的问题.

    Since 2010, the LHC performances are remarkable, more than 25 fb$^{−1}$ have been delivered and recorded by the ATLAS detector. The ATLAS detector is a multi-purpose experiment, one of its main aim was the discovery of the last Standard Model particle predicted : the Higgs boson. In the search for the Higgs boson in the diphoton channel, the non resonant photon pairs production corresponds to the irreducible background. The differential cross-section measurement of photon pair production provides then a deep understanding of the background in $H \\rightarrow \\gamma\\gamma$ channel and it is also an excellent test for the pertubative QCD predictions. With the full dataset collected in 2011 at $\\sqrt{s}$ = 7 TeV, corresponding to 5 fb$^{−1}$ , we performed the differential cross-section measurement of photon pairs production at LHC as a function of four variables, the diphoton mass, transverse momentum, azimuthal separation, and cosine of the polar angle of the leading photon.

    ETS VII is a test satellite to perform in-orbit demonstration of autonomous rendezvous docking (RVD) technology, which will be necessary for advanced space activities in the early 21st century. ETS VII performed three RVD experiment flights, and verified all technical items. ETS VII demonstrated first autonomous RVD between unmanned vehicles, and remote piloted rendezvous flight position accuracy at docking was about 1cm, and acceleration was less than 1.5mG (low impact docking). In the second RVD experiment flight, ETS VII detected attitude anomaly and executed disable abort for safety insurance. We present the results and evaluation of three RVD experiment flights in this paper.

    Summary Background The number of incoming expectant women who have previously experienced cesarean section has increased. This work sought to find the frequency and connections between vaginal deliveries, cesarean sections, and iterative cesarean sections from 2004 to 2008. Material/Methods In all, 828 women with previous cesarean sections were included. From this group, 8282 vaginal deliveries were performed. During these years, 828 women had a history of the cesarean section; in these women, iterative cesarean sections were indicated. To evaluate knowledge of educational material designed for women being prepared for the iterative delivery, we used information compiled on experience from 2002 to 2003; the same approach was used to evaluate the nursing process on interventions and diagnoses of cesarean sections. Results From 2004 to 2008, 11 279 deliveries were performed in the Perinatological Center in České Budějovice; this was significant (Pcesarean section. The number of iterative cesarean sections in women who had already experienced the cesarean section (828) and delivered by cesarean section again is 620. Other data were not significant. Only 2 to 3 pregnancies next to the first cesarean section were statistically significant in 2004 and 2005. Conclusions If a trial of labor after cesarean does not proceed to vaginal birth, the woman will need support and encouragement to express feelings about another cesarean birth. PMID:21278695

    Concerning the future fast neutrons reactors, studied in the frame of the European Fast Reactor (E.F.R.) project, several innovations have been proposed particularly in the field of vapor generators. These vapor generators have the particularity to use two different exchange fluids which can react violently one with the other. The thermodynamic fluid or secondary fluid is water under high pressure (18.5 MPa) which comes under saturated in the inlet of the device, warms and vaporizes inside the nest of boiler-tubes. At the outlet, vapor is overheated. The primary fluid is a liquid metal (sodium for French reactors) which flows outside the nest of boiler-tubes in the opposite direction of the secondary fluid. Several vapor generators models have been carried out. Concerning the European Fast Reactor project, the tubes have a cross-section and are in ferritic steel. Inside the boiler-tubes, the water-vapor flow can be divided into three areas. The first one is the liquid monophasic rate. It ends by the start of the boiling which is nucleated in the shell. Downstream, the two-phase flow passes from a bubbles flow to an annular flow. The liquid is then on the form of shell film and on the form of droplets carried along by the vapor flux. The dryout of the annular film is the start of the third area where there is vapor forced convection. At the present time, there is still no thermohydraulic code in the conditions of the E.F.R. vapor generator. In order to have a reliable size tool, the members of the E.F.R. project have then decided to do a two-phase flow model and have experimented a mono tubular scale model called ``ATLAS`` which represents well the real component for size, fluids and running conditions. The aim of the present work is then, in the frame of this experimental program, to 1)qualify the heat exchange and friction laws which will be later introduced in the thermohydraulic codes of cross-sections vapor generators 2)characterize the dryout phenomenon 3

    The work presented in this thesis lies within the scope of the measurement of the top quark pair production cross-section in the fully hadronic channel at a centre of mass energy of 8 TeV, using the ATLAS detector at the LHC. After introducing the theoretical context of the Standard Model and the physics of the top quark, a description of the ATLAS detector design and of the event reconstruction is given. The first analysis presented focuses on the electromagnetic calorimeter performances, by studying in details the influence of the high voltage variations on the energy scale and resolution, using $Z \\rightarrow ee$ events selected from the 4.5 $\\rm fb^{-1}$ of 7 TeV data collected in 2011. The second part of the thesis is dedicated to jet performance studies.

Cette croissance du temps passé à se déplacer amène à remettre en question la conjecture de Zahavi et apparaît relativement inexplicable en regard du paradigme classique de l’acteur rationnel traditionnellement utilisé dans le champ des transports. Si, dans la littérature, les temps de déplacements sont principalement expliqués par le contexte résidentiel, la forme urbaine et le travail, ce cadre explicatif ne dit rien des processus de décision eux-mêmes qui amènent aux pendularités intensives.À partir d’une enquête qualitative menée auprès de pendulaires français, suisses et belges, cette contribution propose d’analyser les arbitrages et les éléments déterminants des processus de la grande pendularité. Les mobilités quotidiennes pendulaires apparaissent comme le résultat de compromis entre activité professionnelle, attachement résidentiel et choix de vie et prennent ainsi la forme de stratégies de conciliation entre vie privée et vie professionnelle. Ces mobilités spatiales permettent alors paradoxalement la préservation des ancrages résidentiels, sociaux et familiaux.Roots and wings.

    Recent advances in high-throughput technology facilitate massive data collection and sharing, enabling neuroscientists to explore the brain across a large range of spatial scales. One such form of high-throughput data collection is the construction of large-scale mosaic volumes using light microscopy (Chow et al., 2006; Price et al., 2006). With this technology, researchers can collect and analyze high-resolution digitized volumes of whole brain sections down to 0.2 μm. However, until recently, scientists lacked the tools to easily handle these large high-resolution datasets. Furthermore, artifacts resulting from specimen preparation limited volume reconstruction using this technique to only a single tissue section. In this paper, we carefully describe the steps we used to digitally reconstruct a series of consecutive mouse brain sections labeled with three stains, a stain for blood vessels (DiI), a nuclear stain (TO-PRO-3), and a myelin stain (FluoroMyelin). These stains label important neuroanatomical landmarks that are used for stacking the serial sections during reconstruction. In addition, we show that the use of two software applications, ir-Tweak and Mogrifier, in conjunction with a volume flattening procedure enable scientists to adeptly work with digitized volumes despite tears and thickness variations within tissue sections. These applications make processing large-scale brain mosaics more efficient. When used in combination with new database resources, these brain maps should allow researchers to extend the lifetime of their specimens indefinitely by preserving them in digital form, making them available for future analyses as our knowledge in the field of neuroscience continues to expand.

One such form of high-throughput data collection is the construction of large-scale mosaic volumes using light microscopy (Chow et al., 2006; Price et al., 2006. With this technology, researchers can collect and analyze high-resolution digitized volumes of whole brain sections down to 0.2um. However, until recently, scientists lacked the tools to easily handle these large high-resolution datasets. Furthermore, artifacts resulting from specimen preparation limited volume reconstruction using this technique to only a single tissue section. In this paper, we carefully describe the steps we used to digitally reconstruct a series of consecutive mouse brain sections labeled with three stains, a stain for blood vessels (DiI, a nuclear stain (TO-PRO-3, and a myelin stain (FluoroMyelin. These stains label important neuroanatomical landmarks that are used for stacking the serial sections during reconstruction. In addition, we show that the use of two software applications, ir-Tweak and Mogrifier, in conjunction with a volume flattening procedure enable scientists to adeptly work with digitized volumes despite tears and thickness variations within tissue sections. These applications make processing large-scale brain mosaics more efficient. When used in combination with new database resources, these brain maps should allow researchers to extend the lifetime of their specimens indefinitely by preserving them in digital form, making them available for future analyses as our knowledge in the field of neuroscience continues to expand.
