Les données recueillies, relatives à la présence des TIC (Technologies de l’Information et de la Communication dans le cadre de la diffusion du français, et à leur impact sur les modes d’accès à cette langue et à sa culture, nous permettent de décrire et d’analyser les phénomènes et processus mis en œuvre par le développement de l’utilisation de ces technologies, afin de comprendre comment se réalise l’articulation avec les directions déclarées de la politique de diffusion du français. Nous expliquons la manière dont les utilisateurs des TIC intègrent et perçoivent les changements que celles-ci induisent dans les pratiques en langue étrangère. Pour ce faire, nous rendons d’abord compte des différences observées, en les analysant comme des marqueurs d’étapes dans l’adoption de l’innovation, étapes dépendantes de paramètres propres aux contextes dans lesquelles elles interviennent. Puis nous confrontons politique linguistique officielle et politique en actes. Nous proposons enfin un modèle de développement de l’adoption des TIC où nous présentons comme un ensemble cohérent d’étapes les choix de mise en œuvre de leur utilisation.Data was collected in a survey conducted in Francophone cultural institutions worldwide in order to understand how ICT (Information and Communication Technology modifies the ways in which the French language and culture are accessed, taught, and learned.

    Rogge, Karoline S.; Hoffmann, Volker H.

    2010-01-01

    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 System (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 for Germany is based on 42 exploratory interviews with 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 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 the defensive behaviour of incumbents, the observed changes should not be underestimated. We argue that the EU ETS' impact on corporate CO 2 culture and routines may prepare the ground for the transition to a low-carbon sectoral innovation system for power generation technologies.

    The Heavy-Section Steel Technology (HSST) Program is conducted for the Nuclear Regulatory Commission (NRC) by Oak Ridge National Laboratory (ORNL). The program focus is on the development and validation of technology for the assessment of fracture-prevention margins in commercial nuclear reactor pressure vessels. The HSST Program is organized in 11 tasks: program management, fracture methodology and analysis, material characterization and properties, special technical assistance, fracture analysis computer programs, cleavage-crack initiation, cladding evaluations, pressurized-thermal-shock technology, analysis methods validation, fracture evaluation tests, and warm prestressing. The program tasks have been structured to place emphasis on the resolution fracture issues with near-term licensing significance. Resources to execute the research tasks are drawn from ORNL with subcontract support from universities and other research laboratories. Close contact is maintained with the sister Heavy-Section Steel Irradiation (HSSI) Program at ORNL and with related research programs both in the United States and abroad. This report provides an overview of principal developments in each of the II program tasks from October 1, 1991 to March 31, 1992

  18. Nous, animaux fabulateurs et nos technologies de l’illusion

    Directory of Open Access Journals (Sweden)

    Lorenzo Soccavo

    2014-12-01

    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.

    Full Text Available Cet article traite de l’adaptation des démarches d’enseignement en cours d’action, adoptées par les enseignants des sciences et technologies de l’école secondaire. Il vise à comprendre les processus dynamiques de l’adaptation de l’enseignement. Il s’appuie sur des données qui ont été obtenues grâce à un protocole de recherche qualitative axé sur des techniques de groupes de réflexion. Les résultats de la recherche mettent en évidence l’hétérogénéité des parcours d’adaptation des enseignants. Ils soulignent la nécessité du professionnalisme de l’enseignant des sciences et technologies. Ils suggèrent de prendre en considération la complexité des besoins d’adaptation. Ceux-ci commandent en définitive la compatibilité entre les démarches de l’enseignant et les besoins de ses élèves. Le processus d’adaptation est aussi guidé par le plaisir de la reconnaissance, les rapports de l’enseignant aux savoirs, de même que par la défense des valeurs collectives.Mots clé: adaptation de l’enseignement, perception des besoins, enseignement des sciences et technologies This article deals with the adjustment of teaching approaches made by high school science and technology teachers while teaching. It aims at achieving a better understanding of the dynamic processes of teaching adjustment. It relies on a qualitative methodology using focus groups. 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 New technologies, on the one hand, have produced undeniable positive effects, from the acceleration of cultural diffusion to the communication between "worlds" previously unknown; on the other hand, they have become now an instrument to commit new crimes and deviants acts.In the article we will discuss the processes of victimization related to specific offenses (digital identity theft, online paedopornography, cyberstalking and to new forms of addiction due to the new media. The aim is to highlight the dangers of the misuse or abuse of new technologies.S'il est vrai que les nouvelles technologies de communication ont produit des effets positifs indéniables, comme l'accélération de la diffusion culturelle et l'échange entre « mondes » jusque-là inconnus, elles n'en sont pas moins devenues un moyen de commettre des actes déviants et criminels nouveaux.Cet article expose les processus de victimisation liés à certains crimes (comme l'usurpation d'identité, la pédopornographie en ligne, le cyber-harcèlement, et de nouvelles formes de dépendance, afin de mettre en évidence les dangers d'un usage pervers ou délictueux des nouveaux médias.

    1963-05-15

    This report gathers and presents in a simple way results of studies performed at the CEA on issues of spectra in thermal reactors. It is in fact a synthesis of results eventually published in different documents. It first presents the notion of actual cross section as it was introduced by Westcott to characterize the dependence of neutron behaviour on speed distribution. It addresses the case of a homogeneous medium with a conventional model, with the heavy gas model, and with the hydrogen gas model. It generalizes the approach by the differential model. The next part addresses the case of a heterogeneous medium, and the case of presence of moderator nuclei within the fuel [French] Le present rapport a pour objet de rassembler et de presenter de maniere simple les resultats des etudes effectuees au CE.A. sur les problemes de spectres dans les reacteurs thermiques. Ces resultats se trouvaient disperses dans plusieurs documents, ou n'etaient pas encore rediges, et bien que les etudes se poursuivent, il a paru utile d'en faire une synthese provisoire. On a cherche d'autre part a en donner une presentation elementaire, accessible aux lecteurs peu familiarises avec les problemes de thermalisation; dans cet esprit l'expose a une forme didactique, et comporte des rappels de notions bien connues comme par exemple le formalisme de Westcott.

  9. Etude de pratiques d'enseignement relatives a la modelisation en sciences et technologies avec des enseignants du secondaire

    Science.gov (United States)

    Aurousseau, Emmanuelle

    Les modeles sont des outils amplement utilises en sciences et technologies (S&T) afin de representer et d’expliquer un phenomene difficilement accessible, voire abstrait. La demarche de modelisation est presentee de maniere explicite dans le programme de formation de l’ecole quebecoise (PFEQ), notamment au 2eme cycle du secondaire (Quebec. Ministere de l'Education du Loisir et du Sport, 2007a). Elle fait ainsi partie des sept demarches auxquelles eleves et enseignants sont censes recourir. Cependant, de nombreuses recherches mettent en avant la difficulte des enseignants a structurer leurs pratiques d’enseignement autour des modeles et de la demarche de modelisation qui sont pourtant reconnus comme indispensables. En effet, les modeles favorisent la conciliation des champs concrets et abstraits entre lesquels le scientifique, meme en herbe, effectue des allers-retours afin de concilier le champ experimental de reference qu’il manipule et observe au champ theorique relie qu’il construit. L’objectif de cette recherche est donc de comprendre comment les modeles et la demarche de modelisation contribuent a faciliter l’articulation du concret et de l’abstrait dans l’enseignement des sciences et des technologies (S&T) au 2eme cycle du secondaire. Pour repondre a cette question, nous avons travaille avec les enseignants dans une perspective collaborative lors de groupes focalises et d’observation en classe. Ces dispositifs ont permis d’examiner les pratiques d’enseignement que quatre enseignants mettent en oeuvre en utilisant des modeles et des demarches de modelisation. L’analyse des pratiques d’enseignement et des ajustements que les enseignants envisagent dans leur pratique nous permet de degager des connaissances a la fois pour la recherche et pour la pratique des enseignants, au regard de l’utilisation des modeles et de la demarche de modelisation en S&T au secondaire.

    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.

  20. Heavy-Section Steel Technology program fracture issues

    International Nuclear Information System (INIS)

    Pennell, W.E.

    1989-10-01

    Large scale fracture mechanics tests have resulted in the identification of a number of fracture technology issues. Identification of additional issues has come from the reactor vessel materials irradiation test program and from reactor operating experience. This paper provides a review of fracture issues with an emphasis on their potential impact on a reactor vessel pressurized thermal shock (PTS) analysis. Mixed mode crack propagation emerges as a major issue, due in large measure to the poor performance of existing models for the prediction of ductile tearing. Rectification of ductile tearing technology deficiencies may require extending the technology to include a more complete treatment of stress state and loading history effects. The effect of cladding on vessel fracture remains uncertain to the point that it is not possible to determine at this time if the net effect will be positive or negative. Enhanced fracture toughness for shallow flaws has been demonstrated for low strength structural steels. Demonstration of a similar effect in reactor pressure vessel steels could have a significant beneficial effect on the probabilistic analysis of reactor vessel fracture. Further development of existing fracture mechanics models and concepts is required to meet the special requirements for fracture evaluation of circumferential flaws in the welds of ring forged vessels. Fracture technology advances required to address the issues discussed in this paper are the major objective for the ongoing Heavy Section Steel Technology (HSST) program at ORNL. 24 refs., 18 figs

    Improved techniques of fast detection have been applied for determining the fission cross-sections of {sup 235}U and {sup 239}Pu with reference to the absorption cross-section of Boron. Monochromatic neutron beams of 0.0322 eV, 0.0626 eV and 0.275 eV have been employed. Use has been made of a Xe-filled gaseous scintillator and of a low-geometry solid state ion chamber. Both measured alpha and fission rates. The results at the reference energy of 0.0253 eV are: ({sigma}{sub F}){sub 0} {sup 235}U = 588 {+-} 10 barns ({sigma}{sub F}){sub 0} {sup 239}Pu = 738 {+-} 7 barns.

    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. Utilisant Dewey et Dusek comme référence, la documentation portant sur la technologie pédagogique est examinée.

    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)

    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.

Elle intervient à toutes les étapes de construction et ses opérations sont dépendantes des autres chantiers, des entreprises en particulier, et de la configuration changeante des lieux. Les travaux de TS/SU-EM dans les cavernes LHC font donc partie des multiples tâches que TS/LEA a pour mandat de coordonner et gérer. Bien que défini et planifié, le moment exact des interventions est souvent connu sous des délais courts, la méthodologie et les ressources devant alors être adaptées et prêtes au moment décidé. De plus, la section intervient souvent pour des opérations de contrôle de dernière minute par définition non programmées. Une communication permanente et directe entre SU et LEA a été établie pour assurer les échanges indispensables au bon déroulement du projet. Ses formes et moyens seront présentés ici.

    The Energy Technology Division provides materials and engineering technology support to a wide range of programs important to the U.S. Department of Energy. As shown on the preceding page, the Division is organized into eight sections, four with concentrations in the materials area and four 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 Officer, 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. This Overview highlights some major ET research areas. Research related to the operational safety of commercial light water nuclear reactors (LWRs) for the U.S. Nuclear Regulatory Commission (NRC) remains a significant area of interest for the Division. We currently have programs on environmentally assisted cracking, steam generator integrity, and the integrity of high-burnup fuel during loss-of-coolant accidents. The bulk of the NRC research work is carried out by three ET sections: Corrosion and Mechanics of Materials; Irradiation Performance; and Sensors, Instrumentation, and Nondestructive Evaluation

    Aims To examine long-term changes in environmental tobacco smoke (ETS) exposure in British men between 1978 and 2000, using serum cotinine. Design Prospective cohort: British Regional Heart Study. Setting General practices in 24 towns in England, Wales and Scotland. Participants Non-smoking men: 2125 studied at baseline [questionnaire (Q1): 1978–80, aged 40–59 years], 3046 studied 20 years later (Q20: 1998–2000, aged 60–79 years) and 1208 studied at both times. Non-smokers were men reporting no current smoking with cotinine < 15 ng/ml at Q1 and/or Q20. Measurements Serum cotinine to assess ETS exposure. Findings In cross-sectional analysis, geometric mean cotinine level declined from 1.36 ng/ml [95% confidence interval (CI): 1.31, 1.42] at Q1 to 0.19 ng/ml (95% CI: 0.18, 0.19) at Q20. The prevalence of cotinine levels ≤ 0.7 ng/ml [associated with low coronary heart disease (CHD) risk] rose from 27.1% at Q1 to 83.3% at Q20. Manual social class and northern region of residence were associated with higher mean cotinine levels both at Q1 and Q20; older age was associated with lower cotinine level at Q20 only. Among 1208 persistent non-smokers, cotinine fell by 1.47 ng/ml (95% CI: 1.37, 1.57), 86% decline. Absolute falls in cotinine were greater in manual occupational groups, in the Midlands and Scotland compared to southern England, although percentage decline was very similar across groups. Conclusions A marked decline in ETS exposure occurred in Britain between 1978 and 2000, which is likely to have reduced ETS-related disease risks appreciably before the introduction of legislation banning smoking in public places.

    Pennell, W.E.

    1991-01-01

    Technology for the analysis of crack initiation and arrest is central to the reactor pressure vessel fracture-margin-assessment process. Regulatory procedures for nuclear plants utilize this technology to assure the retention of adequate fracture-prevention margins throughout the plant operating license period. As nuclear plants age and regulatory procedures dictate that fracture-margin assessments be performed, interest in the fracture-mechanics technology incorporated into those procedures has heightened. This has led to proposals from a number of sources for development and refinement of the underlying crack-initiation and arrest-analysis technology. This paper presents an overview of ongoing Heavy-Section Steel Technology (HSST) Program research aimed at refining the fracture toughness data used in the analysis of fracture margins under pressurized-thermal-shock loading conditions. 33 refs., 13 figs

    The neutron fission cross section of uranium-235 has been measured between 4 ev and 20 kev by the time of flight method with the Saclay electron linear accelerator as a pulsed neutron source. After a brief description of the experimental apparatus and the conditions of work during the experiment, the curve {sigma}{sub F} {radical}E in the energy range studied is shown. This curve is then analyzed by the ''area'' method and a set of {sigma}{sub 0} {gamma}{sub F} values is obtained. With {sigma}{sub 0} {gamma} values measured in other laboratories, it is possible to compute fission widths for several resonances and to study their distribution. This distribution is then compared to Porter-Thomas distributions with different values of the number of exit channels. (authors) [French] La section efficace de fission de l'uranium--235 a ete mesuree entre 4 eV et 20 KeV par la methode du temps de vol en utilisant l'accelerateur lineaire a electrons de Saclay comme source pulses de neutrons. Apres une rapide description de l'appareillage experimental et des conditions de fonctionnement au cours de l'experience, on presente la courbe {sigma}{sub F} {radical}E obtenue dans la game d'energie etudiee. Cette courbe est ensuite analysee par la methode de surface des resonances et un lot de valeurs de {sigma}{sub 0} {gamma}{sub F} est obtenue. Conjuguee avec les valeurs de {sigma}{sub 0} {gamma} obtenues dans d'autres laboratoires, cette analyse permet de calculer les largeurs de fission pour plusieurs resonances et d'etudier leur distribution. Cette distribution est ensuite comparee aux distributions de Porter et Thomas correspondant a differentes valeurs du nombre de voies de sortie. (auteurs)

Regulatory procedures for nuclear plants utilize this technology to assure the retention of adequate fracture-prevention margins throughout the plant operating license period. As nuclear plants age and regulatory procedures dictate that fracture-margin assessments be performed, interest in the fracture-mechanics technology incorporated into those procedures has heightened. This has led to proposals from a number of sources for development and refinement of the underlying crack-initiation and arrest-analysis technology. An important element of the Heavy-Section Steel Technology (HSST) Program is devoted to the investigation and evaluation of these proposals. This paper presents the technological bases and fracture-margin assessment objectives for some of the recently proposed crack-initiation and arrest-technology developments. The HSST Program approach to the evaluation of the proposals is described and the results and conclusions obtained to date are presented

    The aim of this study was to explore how the observed ability to use everyday technology (ET), intrapersonal capacities and environmental characteristics related to ET use contributes to the likelihood of return to work in people with ABI. The aim was also to explore whether these variables added to the likelihood of return to work to earlier defined significant variables in the group: age, perceived ADL ability and perceived ability in ET use. A cross-sectional study. The Management of Everyday Technology Assessment (META), the short version of the Everyday Technology Use Questionnaire (S-ETUQ) and a revised version of the ADL taxonomy were used to evaluate 74 people with ABI. Individual ability measures from all assessments were generated by Rasch analyses and used for additional statistical analysis. The univariate analyses showed that the observed ability to use ET, as well as intrapersonal capacities and environmental characteristics related to ET use were all significantly associated with returning to work. In the multivariate analyses, none of these associations remained. The explanatory precision of return to work in people with ABI increased minimally by adding the observed ability to use ET and the variables related to ET use when age, perceived ability in ET use and ADL had been taken in account.

    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

  13. Research and field tests of staged fracturing technology for casing deformation sections in horizontal shale gas wells

    Directory of Open Access Journals (Sweden)

    2018-02-01

    Full Text Available Horizontal shale gas well fracturing is mostly carried out by pumping bridge plugs. In the case of casing deformation, the bridge plug can not be pumped down to the designated position, so the hole sections below the deformation could not be stimulated according to the design program. About 30% of horizontal shale gas wells in the Changning and Weiyuan Blocks, Sichuan Basin, suffer various casing deformation after fracturing. Previously, the hole sections which could not be stimulated due to casing deformation were generally abandoned. As a result, the resources controlled by shale gas wells weren't exploited effectively and the fracturing effect was impacted greatly. There are a lot of difficulties in investigating casing deformation, such as complex mechanisms, various influencing factors and unpredictable deformation time. Therefore, it is especially important to seek a staged fracturing technology suitable for the casing deformation sections. In this paper, the staged fracturing technology with sand plugs inside fractures and the staged fracturing technology with temporary plugging balls were tested in casing deformation wells. The staged fracturing technology with sand plugs inside fractures was carried out in the mode of single-stage perforation and single-stage fracturing. The staged fracturing technology with temporary plugging balls was conducted in the mode of single perforation, continuous fracturing and staged ball dropping. Then, two kinds of technologies were compared in terms of their advantages and disadvantages. Finally, they were tested on site. According to the pressure response, the pressure monitoring of the adjacent wells and the microseismic monitoring in the process of actual fracturing, both technologies are effective in the stimulation of the casing deformation sections, realizing well control reserves efficiently and guaranteeing fracturing effects.

    a) Measurements of neutron induced fission cross-sections in the low energy region. The variation of the fission cross sections of several fissile isotopes has been measured and analysed, for neutron energies below 0,025 eV. The monochromator was a crystal spectrometer used in conjunction with a mechanical velocity selector removing higher order Bragg reflections. The fissile material was laid down on the plates of a fission chamber by painting technic. An ionization chamber, having its plates coated with thin {sup 10}B layers, was used as the neutron flux monitor. b) Measurement of the fission cross section of {sup 235}U. We intend to measure the variation of the neutron induced fission cross section of {sup 235}U over the neutron energy range from 1 keV by the time of flight method. The neutron source is the uranium target of a pulsed 28 MeV electron linear accelerator. The detector is a large fission chamber, with parallel plates, containing about 10 g of {sup 235}U (20 deposits of 25 cm diameter). The relative fission data were corrected for the neutron spectrum measured with a set of BF{sub 3} proportional counters. c) Mean number {nu} of neutrons emitted in neutron induced fission. We measured the value of {nu} for several fissile isotopes in the case of fission induced by 14 MeV neutrons. The 14 MeV neutrons were produced by D (t, n) {alpha} reaction by means of a 300 kV Cockcroft Walton generator. (author)Fren. [French] a) Mesures de sectionficaces de fission a basse energie.

    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.

  6. Relations de Dispersion et Diffusion des Glueballs et des Mesons dans la Theorie de Jauge U(1)(2+1) Compacte

    Science.gov (United States)

    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.

    The thermal and hydrodynamic phenomena occurring during a power excursion were studied in an out-of-pile loop with a water cooled channel at low pressure (1 to 4 atm. abs. ). Circular and rectangular test sections with electrically heated walls of two different thermal diffusivity materials(aluminium and stainless steel) were used. The rectangular test sections were 600 mm long, 35 mm wide and had a 2, 9 mm gap; they simulate two half plates of the M.T.R. fuel element. Natural or forced convection are possible in the test section; the water height above it can be varied from 2.8 to 8 meters and the maximum allowed pressure at its outlet is 4 atm. abs.The heating source is a series of lead batteries which is able to generate, for short periods of time, 85 volts and 25000 amperes; linear, square or exponential power rise versus time can be realized. A 14 channels tape recorder (0-10 000 Hz bandwidth; is used for the measurements of temperature (8/100 mm diameter thermocouple), pressure ('Statham' pressure transducers) and void fraction (X rays). More than 500 tests have been carried out. The influence of the initial water temperature, flow rate, pressure, water height on the water ejections, pressure variations and void fraction in the test section were studied. Tests with energies up to 3000 W/cm in 50 milliseconds were attempted. The energy above which the instabilities appear was determined. An interpretation of the observed phenomena and a simplified theoretical model are presented.

    Full Text Available 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.

  18. Exploring an optimal wavelet-based filter for cryo-ET imaging.

    Science.gov (United States)

    Huang, Xinrui; Li, Sha; Gao, Song

    2018-02-07

    Cryo-electron tomography (cryo-ET) is one of the most advanced technologies for the in situ visualization of molecular machines by producing three-dimensional (3D) biological structures. However, cryo-ET imaging has two serious disadvantages-low dose and low image contrast-which result in high-resolution information being obscured by noise and image quality being degraded, and this causes errors in biological interpretation. The purpose of this research is to explore an optimal wavelet denoising technique to reduce noise in cryo-ET images. We perform tests using simulation data and design a filter using the optimum selected wavelet parameters (three-level decomposition, level-1 zeroed out, subband-dependent threshold, a soft-thresholding and spline-based discrete dyadic wavelet transform (DDWT)), which we call a modified wavelet shrinkage filter; this filter is suitable for noisy cryo-ET data. When testing using real cryo-ET experiment data, higher quality images and more accurate measures of a biological structure can be obtained with the modified wavelet shrinkage filter processing compared with conventional processing. Because the proposed method provides an inherent advantage when dealing with cryo-ET images, it can therefore extend the current state-of-the-art technology in assisting all aspects of cryo-ET studies: visualization, reconstruction, structural analysis, and interpretation.

    The thermal and hydrodynamic phenomena occurring during a power excursion were studied in an out-of-pile loop with a water cooled channel at low pressure (1 to 4 atm. abs. ). Circular and rectangular test sections with electrically heated walls of two different thermal diffusivity materials(aluminium and stainless steel) were used. The rectangular test sections were 600 mm long, 35 mm wide and had a 2, 9 mm gap; they simulate two half plates of the M.T.R. fuel element. Natural or forced convection are possible in the test section; the water height above it can be varied from 2.8 to 8 meters and the maximum allowed pressure at its outlet is 4 atm. abs.The heating source is a series of lead batteries which is able to generate, for short periods of time, 85 volts and 25000 amperes; linear, square or exponential power rise versus time can be realized. A 14 channels tape recorder (0-10 000 Hz bandwidth; is used for the measurements of temperature (8/100 mm diameter thermocouple), pressure ('Statham' pressure transducers) and void fraction (X rays). More than 500 tests have been carried out. The influence of the initial water temperature, flow rate, pressure, water height on the water ejections, pressure variations and void fraction in the test section were studied. Tests with energies up to 3000 W/cm in 50 milliseconds were attempted. The energy above which the instabilities appear was determined. An interpretation of the observed phenomena and a simplified theoretical model are presented.

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.

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

    Science.gov (United States)

    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 dissociation, ionisation, and charge exchange cross-sections of molecular hydrogen ions H{sub 2}{sup +} passing through various gases, have been measured as a function of the energy of the ions. The energy range studied was from 25 to 250 keV. The reaction products, analysed by a magnetic field according to their e/m ratio, are collected on scintillation detectors. Two methods have made it possible to separate the various reactions leading to the formation of particles having the same e/m ratio. The first separates the particles according to their energy, the other selects those arriving simultaneously on two different detectors. The results show a large variation in the charge exchange cross-section with the energy of the H{sub 2}{sup +} ions. The variations in the dissociation and ionisation cross-sections are less pronounced. For a given energy, the values of the cross-sections increase with the atomic weight of the target particles. These measurements have been extended to the case of H{sub 2}{sup +} ions passing through a target of charged particles. Preliminary results show an increase in the cross-sections as compared to the preceding case. Finally the scattering of the reaction products has been studied; this scattering is due to the fact that the molecules formed during a reaction are in an unstable state and the nuclei or atoms diverge from each other.

    We propose a method for calculating the biological efficiency of fast neutrons emitted by in-pile fission sources. This method justifies the empirical theory of Albert and Welton. In making simple assumptions concerning the cross-sections, we have supposed that the propagation can ben reduced to a mono-kinetic problem. A system of orthonormal functions is then set up making it possible to calculate the flux leaving a planar source. This method generalises the results obtained by Platzek to the case where the elastic cross-sections are not isotropic, and make it possible in particular to define a displacement cross-section: extension of the diffusion coefficient. This method can be generalised to the case of neutron diffraction as a function of time, and to the study of slowing-down. Numerical results are given in an appendix for the following: H{sub 2}O, D{sub 2}O, Fe, Be, Pb, CH, CH{sub 2}. These cross-sections have been verified experimentally in water and in graphite for neutrons of 2.5 and 14 MeV using a SAMES accelerator and a 2 MeV Van De Graaff.

Nous construisons alors un systeme de fonctions orthonormales qui permet de calculer le flux issu d'une source plane. Cette methode generalise les resultats obtenus par Platzek au cas ou les sections efficaces elastiques ne sont pas isotropes et en particulier permet de definir une section efficace de deplacement: extension du coefficient de diffusion.

  6. Evaluation of soil characterization technologies using a stochastic, value-of-information approach

    International Nuclear Information System (INIS)

    Kaplan, P.G.

    1993-01-01

    The US Department of Energy has initiated an integrated demonstration program to develop and compare new technologies for the characterization of uranium-contaminated soils. As part of this effort, a performance-assessment task was funded in February, 1993 to evaluate the field tested technologies. Performance assessment can be cleaned as the analysis that evaluates a system's, or technology's, ability to meet the criteria specified for performance. Four new technologies were field tested at the Fernald Environmental Management Restoration Co. in Ohio. In the next section, the goals of this performance assessment task are discussed. The following section discusses issues that must be resolved if the goals are to be successfully met. The author concludes with a discussion of the potential benefits to performance assessment of the approach taken. This paper is intended to be the first of a series of documentation that describes the work. Also in this proceedings is a paper on the field demonstration at the Fernald site and a description of the technologies (Tidwell et al, 1993) and a paper on the application of advanced geostatistical techniques (Rautman, 1993). The overall approach is to simply demonstrate the applicability of concepts that are well described in the literature but are not routinely applied to problems in environmental remediation, restoration, and waste management. The basic geostatistical concepts are documented in Clark (1979) and in Issaks and Srivastava (1989). Advanced concepts and applications, along with software, are discussed in Deutsch and Journel (1992). Integration of geostatistical modeling with a decision-analytic framework is discussed in Freeze et al (1992). Information-theoretic and probabilistic concepts are borrowed from the work of Shannon (1948), Jaynes (1957), and Harr (1987). The author sees the task as one of introducing and applying robust methodologies with demonstrated applicability in other fields to the problem at hand

  12. Theories and calculation methods for regional objective ET

    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 neutron total cross sections have been measured over the energy range 400 keV - 1200 keV for fluorine, aluminium, silicon, phosphorus, vanadium, chromium, manganese, iron, nickel, cobalt and lead with an energy spread of 3 keV. The neutrons were produced by the T (p,n) {sup 3}He reaction, the proton beam was supplied by a 2 MeV Van de Graaff. The structure in {sup 56}Fe has been studied in a more detailed way by measuring six angular distributions in the above range and the elastic scattering excitation curves at four angles. The measurements have made it possible to show the existence of the compound nucleus, as well as the presence of an intermediate structure in certain nuclei.

    1975-01-01

    The testing of the intermediate pressure vessels is a major activity under the Heavy Section Steel Technology Program. A primary objective of these tests is to develop or verify methods of fracture prediction, through the testing of selected structures and materials, in order that a valid basis can be established for evaluating the serviceability and safety of light-water reactor pressure vessels. These vessel tests were planned with sufficiently specific objectives that substantial quantitative weight could be given to the results. Each set of testing conditions was chosen so as to provide specific data by which analytical methods of predicting flaw growth, and in some cases crack arrest, could be evaluated. Every practical effort was made to assure that results would be relevant to some aspect of real reactor pressure vessel performance through careful control of material properties, selection of test temperatures, and design of prepared flaws. 5 references

    This report consists of three sections. The first is concerned with the description of different pumps which have been constructed, tests on these which have been completed and the results obtained. The second section presents a theoretical method for the determination of the coefficients, taking in account the break of the magnetic circuit. It is shown that the preliminary design calculations of the annular pumps can be made, neglecting the break of the magnetic circuit, by further assigning essential magnitudes (pressure, losses) with easily calculated coefficients. The third section of this report uses the theoretical bases exposed in the second section, and develop a new annular pump calculation method which takes-into account both the current out of balance and any type of winding.

    Directory of Open Access Journals (Sweden)

    Serge Agostinelli

    2011-06-01

    Full Text Available Cet article théorique explore comment les concepts de structure et d’action permettent une approche originale du concept de compétence dans le domaine des TIC. Cette approche relève d’une recherche de compatibilité entre des modèles issus des Technologies qui proposent les structures socio-techniques et ceux des Sciences Humaines qui organisent l’action des individus. Les modèles théoriques invoqués de domaines disciplinaires différents (sociologie, ethnométhodologie, psychologie sociale, linguistique, sciences de l’éducation et sciences de l’information-communication donnent au concept de compétence en TIC une nouvelle consistance, plus anthropocentrée et moins technico-pratique. Ils posent la question du rapport entre micro et macro, du rapport de l’individu au groupe, et posent aussi la question ontologique des structures. Les compétences ne se réduisent pas à la seule connaissance des aspects techniques, mais sont élargies à la maîtrise des conditions d’utilisation adéquate et des possibilités offertes par la technique. Utiliser les technologies, c’est construire de la relation grâce aux compétences communicatives des TIC.This theoretical article investigates how the concepts of structure and action allow an original approach of the concept of skill in the field of ICT. This approach concerns a search for compatibility between stemming models Technologies which propose the socio-technical structures and those of the Human Sciences who organize the action of the individuals. The theoretical models called by different disciplinary domains (sociology, ethnomethodology, social psychology, linguistic, education, communication and information science give to the concept of skill in ICT a new consistency, more anthropology centred and less technico-practical. They ask the question of the relationship between micro and macro, the relationship of the individual to the group, and also ask the ontological question

    The role of endothelin (ET)(A)-ET(B) receptor cross-talk in limiting the ET(A) receptor antagonist inhibition of ET-1 constriction is revealed by the partial or complete dependency of the ET(A) receptor antagonist inhibition on functional removal of the ET(B) receptor. Although functional removal of the ET(B) receptor is generally accomplished with ET(B) receptor antagonist, a novel approach using rats containing a naturally occurring deletion mutation in the ET(B) receptor [rescued "spotting lethal" (sl) rats; ET(B)(sl/sl)] demonstrated increased ET(A) receptor antagonist inhibition of ET-1 constriction in vena cava. We investigated whether this deletion mutation was also sufficient to remove the ET(B) receptor dependency of the ET(A) receptor antagonist inhibition of ET-1 constriction in the basilar artery. Consistent with previous reports, ET-1 plasma levels were elevated in ET(B)(sl/sl) as compared with ET(B)(+/+) rats. ET(B) receptor antagonist failed to relax the ET-1 constricted basilar artery from ET(B)(+/+) and ET(B)(sl/sl) rats. Relaxation to combined ET(A) and ET(B) receptor antagonist was greater than relaxation to ET(A) receptor antagonist in the basilar artery from ET(B)(+/+) and, unexpectedly, ET(B)(sl/sl) rats. These findings confirm the presence of ET(A)-ET(B) receptor cross-talk in the basilar artery. We speculate that mutant ET(B) receptor expression produced by alternative splicing may be sufficient to allow cross-talk.

    Gallay, Sylvain

    Dans le processus de developpement d'avion, la solution retenue doit satisfaire de nombreux criteres dans de nombreux domaines, comme par exemple le domaine de la structure, de l'aerodynamique, de la stabilite et controle, de la performance ou encore de la securite, tout en respectant des echeanciers precis et minimisant les couts. Les geometries candidates sont nombreuses dans les premieres etapes de definition du produit et de design preliminaire, et des environnements d'optimisations multidisciplinaires sont developpes par les differentes industries aeronautiques. Differentes methodes impliquant differents niveaux de modelisations sont necessaires pour les differentes phases de developpement du projet. Lors des phases de definition et de design preliminaires, des methodes rapides sont necessaires afin d'etudier les candidats efficacement. Le developpement de methodes ameliorant la precision des methodes existantes tout en gardant un cout de calcul faible permet d'obtenir un niveau de fidelite plus eleve dans les premieres phases de developpement du projet et ainsi grandement diminuer les risques associes. Dans le domaine de l'aerodynamisme, les developpements des algorithmes de couplage visqueux/non visqueux permettent d'ameliorer les methodes de calcul lineaires non visqueuses en methodes non lineaires prenant en compte les effets visqueux. Ces methodes permettent ainsi de caracteriser l'ecoulement visqueux sur les configurations et predire entre autre les mecanismes de decrochage ou encore la position des ondes de chocs sur les surfaces portantes. Cette these se focalise sur le couplage entre une methode d'ecoulement potentiel tridimensionnelle et des donnees de section bidimensionnelles visqueuses. Les methodes existantes sont implementees et leurs limites identifiees. Une methode originale est ensuite developpee et validee. Les resultats sur une aile elliptique demontrent la capacite de l'algorithme a de grands angles d'attaques et dans la region post

    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. L'apprentissage des langues assisté par la technologie (TeLL: mise à jour et énoncé de principes pour les cours d’anglais à des fins universitaires La variété et la profusion de technologies actuellement disponibles ont engendré des possibilités nouvelles et des défis pour les enseignants en langue. Cette étude passe en revue la recherche récente consacrée à l'apprentissage des langues assisté par la technologie (TeLL et examine sa pertinence éventuelle pour la pédagogie, les programmes, l'évaluation et l'enseignement de l’anglais à des fins universitaires. Les résultats de cette étude révèlent un intérêt croissant de la recherche sur l'apprentissage des langues assisté par la technologie pour le vocabulaire, la grammaire et l'écriture, mais un intérêt moindre pour la langue parlée, la langue écoutée et pour la lecture.

  20. Chinese companies’ awareness and perceptions of the Emissions Trading Scheme (ETS): Evidence from a national survey in China

    International Nuclear Information System (INIS)

    Yang, Lin; Li, Fengyu; Zhang, Xian

    2016-01-01

    China announced the launch of a national Emissions Trading Scheme (ETS) in 2017; however, companies appear show little enthusiasm for participation in the ETS in China. This paper identifies the factors affecting companies’ awareness and perceptions of ETS by conducting a national survey based on an online questionnaire from May to November 2015 in seven carbon trading pilots. The results indicate that companies’ attitudes towards the ETS are positively influenced by government regulations and policy, public relations management and estimated economic benefit. Of these, public relations management is the decisive factor and estimated economic benefit is confirmed to be a relatively weak predictor. A company's environmental and energy strategy exerts insignificant effects on its preference for the ETS, although the sampled companies are very willing to save energy and reduce emissions. There exists an inverted U-shape relationship between a company's level of mitigation technologies and its attitudes towards the ETS. The carbon price fails to stimulate companies to upgrade mitigation technologies. The majority of companies treat participation in the ETS only as a means of improving ties with governments, as well as of earning a good social reputation, rather than as a cost-effective mechanism to mitigate greenhouse gas emissions. - Highlights: • This paper provides a timely study of companies’ awareness of ETS in China. • ETS is not approved by companies as a cost-effective mitigation tool. • External pressure is the most important indicator. • Carbon price fails to promote companies to upgrade mitigation technologies.

    Han, Heeyoung; Nelson, Erica; Wetter, Nathan

    2014-02-01

    This study investigated medical students' online learning technology needs at a medical school. The study aimed to provide evidence-based guidance for technology selection and online learning design in medical education. The authors developed a 120-item survey in collaboration with the New Technology in Medical Education (NTIME) committee at the Southern Illinois University School of Medicine (SIUSOM). Overall, 123 of 290 medical students (42%) at the medical school participated in the survey. The survey focused on five major areas: students' hardware and software use; perception of educational technology (ET) in general; online behaviours; perception of ET use at the school; and demographic information. Students perceived multimedia tools, scheduling tools, communication tools, collaborative authoring tools, learning management systems and electronic health records useful educational technologies for their learning. They did not consider social networking tools useful for their learning, despite their frequent use. Third-year students were less satisfied with current technology integration in the curriculum, information sharing and collaborative learning than other years. Students in clerkships perceived mobile devices as useful for their learning. Students using a mobile device (i.e. a smartphone) go online, text message, visit social networking sites and are online during classes more frequently than non-users. Medical students' ET needs differ between preclinical and clinical years. Technology supporting ubiquitous mobile learning and health information technology (HIT) systems at hospitals and out-patient clinics can be integrated into clerkship curricula. © 2014 John Wiley & Sons Ltd.

    The aim was to explore the relationships between difficulties in the use of everyday technology (ET) and the ability to perform activities of daily life (ADL) in the home and in society and in the workplace in people with acquired brain injury (ABI). The investigation comprises an explorative cross-sectional study of 74 people with ABI. The short version of the Everyday Technology Use Questionnaire (S-ETUQ) and a revised version of the ADL taxonomy were used to evaluate the participants. Rasch-generated person ability measures of ET use and ADL were used in correlation analyses, in group comparisons by ANOVA and in logistic regressions. Difficulty in the use of ET was significantly correlated with ADL limitations. People who worked full- or part-time had significantly higher ability to use ET than those with some type of full-time, long-term sickness compensation. The ability to use ET, ADL ability and age were significantly related to return to work. The ability to use ET is related to all areas of everyday functioning in people with ABI. Therefore, a patient's ability to use ET needs to be considered in rehabilitation strategies following an ABI to enhance the patient's performance of activities in the home and in society and to support his or her likelihood of returning to work.

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

    Full Text Available This paper critically reviews various learning preferences and human intelligence theories and models with a particular focus on the implications for online learning. It highlights a few key models, Gardner’s multiple intelligences, Fleming and Mills’ VARK model, Honey and Mumford’s Learning Styles, and Kolb’s Experiential Learning Model, and attempts to link them to trends and opportunities in online learning with emerging technologies. By intersecting such models with online technologies, it offers instructors and instructional designers across educational sectors and situations new ways to think about addressing diverse learner needs, backgrounds, and expectations. Learning technologies are important for effective teaching, as are theories and models and theories of learning. We argue that more immense power can be derived from connections between the theories, models and learning technologies. Résumé : Cet article passe en revue de manière critique les divers modèles et théories sur les préférences d’apprentissage et l’intelligence humaine, avec un accent particulier sur les implications qui en découlent pour l’apprentissage en ligne. L’article présente quelques-uns des principaux modèles (les intelligences multiples de Gardner, le modèle VAK de Fleming et Mills, les styles d’apprentissage de Honey et Mumford et le modèle d’apprentissage expérientiel de Kolb et tente de les relier à des tendances et occasions d’apprentissage en ligne qui utilisent les nouvelles technologies. En croisant ces modèles avec les technologies Web, les instructeurs et concepteurs pédagogiques dans les secteurs de l’éducation ou en situation éducationnelle se voient offrir de nouvelles façons de tenir compte des divers besoins, horizons et attentes des apprenants.

    Full Text Available From the mid-19th century, vast improvements in steamship and communication technology created an interlinked network of port-cities in the Indian Ocean and maritime Asia. Though Rangoon and Penang had starkly different relationships to colonial rule, they shared a lineage as multi-ethnic ports where various communities had existed side-by-side for centuries. The advent of the Victorian era fostered new class and racial divisions between them, yet also created a new feuilleton culture in the port-city with the mushrooming of newspapers, books, and a new reading public. Diverse ethnic and linguistic communities sought platforms to articulate their concerns and inform themselves of the affairs of the world, and their place within it. Burmese in Rangoon, imbued with a renewed sense of cultural pride, absorbed the rising tide of anticolonialism nationalism echoing throughout the world. Penangites transformed their society using the liberal, cosmopolitan tenants of imperial citizenship to make political and cultural claims for a multi-ethnic society. The vibrant, outward-looking atmosphere of the colonial port-city as a node of information and cultural exchange made Penang and Rangoon the intellectual staging grounds for new visions of the nation.À compter du milieu du xixe siècle, d’importantes améliorations dans la navigation à vapeur et les technologies des communications ont créé un réseau de villes portuaires dans l’Océan indien et l’Asie maritime. Même si Rangoon et Penang avaient des relations divergentes avec la puissance coloniale, elles participaient d’un type identique comme ports où cohabitaient depuis des siècles des communautés d’ethnies différentes. L’ère victorienne conduisit à de nouvelles divisions sociales et ethniques, mais suscita dans la ville portuaire une nouvelle culture littéraire avec le foisonnement des journaux, des livres et un nouveau lectorat.

    Single-differential, partial and total ionization cross sections for the proton-hydrogen collision system at low energy range (0.1-10 keV/amu) are determined by using the electron translation factor corrected molecular-orbital close-coupling method. Full convergence of ionization cross sections as a function of H{sub 2}{sup +} molecular basis size is achieved by including up to 10 bound states, and 11 continuum partial waves. The present cross sections are in an excellent agreement with the recent experiments of Shah et al., but decrease more rapidly than the cross sections measured by Pieksma et al. with decreasing energy. The calculated cross section data are included in this report. (author)

    The authors describe the technique used to measure the effective absorption and neutron-yield cross-sections of a fissionable sample. These two values are determined by analysing the signals due to the variation in reactivity (over-all signal) and the local perturbation in the flux (local signal) produced by the oscillating sample. These signals are standardized by means of a set of samples containing quantities of fissionable material ({sup 235}U) and an absorber, boron, which are well known. The measurements are made for different neutron spectra characterized by lattice parameters which constitute the central zone within which the sample moves. This technique is used to study the effective cross-sections of uranium-plutonium alloys for different heavy-water and graphite lattices in the MINERVE and MARIUS critical assemblies. The same experiments are carried out on fuel samples of different irradiations in order to determine the evolution of effective cross-sections as a function of the spectrum and the irradiations. (authors) [French] On decrit la methode utilisee pour mesurer les sections efficaces effectives d'absorption et de production de neutrons d'un echantillon fissile. Ces deux grandeurs sont determinees en analysant les signaux dus a la variation de reactivite (signal global) et a la perturbation locale de flux (signal local) produits par l'echantillon oscillant. Ces signaux sont etalonnes a l'aide d'un jeu d'echantillons dont les teneurs en materiau fissile ({sup 235}U) et en absorbeur (bore) sont bien connues.

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.

    2013-01-01

    To investigate and describe how persons with an acquired brain injury (ABI) manage everyday technology (ET) in their daily activities and to explore whether the ability to manage ET was related to the severity of the disability. Eighty-one persons with ABI were observed while managing ET by using the Management of Everyday Technology Assessment (META). The Glasgow Outcome Scale-Extended (GOSE) was used to assess the severity of disability after the ABI. A computer application of a Rasch measurement model was used to generate measures of the participants' ability to manage ET and the measures were compared groupwise with analysis of covariance (ANCOVA). The degree of severity of disability had a significant main effect on the ability to manage ET. The groups with severe and moderate disability exhibited a significantly lower ability to manage ET compared to the group with good recovery. The result indicates that the ability to manage ET in daily activities can be related to the global severity of disability after ABI. This demonstrates the importance of considering the ability to manage ET to support the performance of activities at home, at work and in society in persons with ABI.

To examine the possibility of using a collaboration of Human Computer Interaction (HCI and Educational Technology (ET to develop innovative improvements to the education system, the curricula of these two areas of study were lexically analyzed and compared. As a further example, the curriculum of a joint course in HCI and ET was also lexically analyzed and the contents were examined. These analyses can be used as references in the development of human resources for use in advanced learning environments.

  10. Perceived usefulness and culture as predictors of teachers attitudes towards educational technology in South Africa

    Directory of Open Access Journals (Sweden)

    Samantha Anne Hart

    2015-11-01

    Full Text Available The use of educational technology (ET worldwide is increasing rapidly, and South Africa is no exception. Grouped amongst the emerging economies of the world, South Africa's information and communication technology (ICT infrastructure is often mentioned as one of the key factors leading to the growth of the country. Integrating ICT into education has become a priority for the South African government. However, it is necessary to move beyond merely providing physical access to ICT's in order for integration to be successful. The integration of ET in schools is greatly influenced by teachers' attitudes towards the technology. The aim of this study was to investigate teachers' attitudes towards educational technology and the factors that are thought to influence teachers' attitudes, namely, perceived usefulness, perceived cultural relevance, perceived competence and access to ET. A convenience sample of 117 teachers in the Johannesburg area, from both public and private schools, across foundation, intermediate and senior phase, completed the Attitudes Towards Computer Scale. Teachers' attitudes were generally positive. The strongest predictor of teachers' attitudes was perceived usefulness followed by perceived cultural relevance. Thus, it is evident that when integrating ET into schools, attention must be paid to teachers perceptions of the utility of ET in order for integration to be successful. Having access to ET and the competence to use ET are not enough for the successful integration of ET in schools.

    This report, written in partnership with I4CE and IFPen, provides the first complete and comprehensive assessment of the EU Commission's proposal and its coherence with the 2030 Framework for Climate and Energy policies, demonstrating that: 1 - Re-calibrating the EU ETS requires considering its interactions with complementary climate and energy policies by 2030. Interactions between different policies may induce additional costs vis-a-vis an optimal transition to a low-carbon economy. 2 - Introducing the Market Stability Reserve is necessary to support the ambition of the EU ETS. Guaranteeing MSR effectiveness calls for a governing framework to be established before 2030. 3 - The free allocation mechanism for Phase IV requires more flexible and targeted allocation to sectors most exposed to carbon leakage risk. 4 - Expanding the EU ETS scope with the inclusion of the road transport sector may not necessarily be the most cost-effective way to achieve the GHG 2030 target. 5 - Considering the large scale of ETS auction revenues by 2030, the use of ETS proceeds by the European Commission and by Member States constitutes an increasingly relevant funding source to support decarbonization efforts in non-ETS sectors and to finance R and D in low carbon technologies

  19. Evaluating the EU ETS impacts on profits, investments and prices of the Italian electricity market

    International Nuclear Information System (INIS)

    Bonenti, Francesca; Oggioni, Giorgia; Allevi, Elisabetta; Marangoni, Giacomo

    2013-01-01

    Climate change is a global issue, but actions to mitigate its development are regional. Europe has taken the leadership in the carbon emission policy by introducing the Emissions Trading Scheme (EU ETS), formerly regulated by Directive 2003/87/EC and since 2013 by Directive 2009/29/EC. This new Directive imposes a full auctioning system for allocating CO 2 allowances to the power sector and encourages the use of renewable energy sources. We investigate the economic impacts of the EU ETS on the Italian electricity market using a power generation expansion model. We adopt a technological representation of the energy market that also accounts for power exchanges with foreign countries and we assume that generators operate in different zones connected by interconnections with limited capacity. We study both an oligopolistic and a perfectly competitive behavior of Italian generators and we compare the corresponding outcomes under different EU ETS scenarios. Our analysis shows that, in perfect competition, generators generally invest more than in an oligopolistic framework, but in both market configurations, investments in Italy are mainly concentrated in fossil-fired plants, especially in 2020. This happens also when incentives are given to renewables. The developed models are implemented as complementarity problems and solved in GAMS using the PATH solver. - Highlights: • We evaluate the EU-ETS impacts on the Italian electricity market. • We model different EU-ETS scenarios and energy market organizations. • Generators can invest in new capacity. • Investments in CCGT plants are preferable to those in clean technologies. • Profits depend on market organization and on ETS allowance allocation policies

    Science.gov (United States)

    Schmidt, Anja; Thordarson, Thorvaldur; Oman, Luke D.; Robock, Alan; Self, Stephen

    2014-01-01

    Here we respond to the comments by Cole-Dai et al. [2014] on our article Schmidt et al. [2012]. Specifically, in response to section 2 of their reply, we argued in Schmidt et al. [2012] that based on previously published estimates of the volatile release height during the 1783-1784 C.E. Laki eruption, the lack of a sulfur massindependent fractionation (MIF) anomaly is expected. In other words, no previous study on Laki ever argued that this eruption emitted SO2 into altitudes >13-15 km. In section 2.3, Cole-Dai et al. [2014] argue that the nonzero ?33S value of their Laki sample 1 may be explained by a short-lived explosive phase at Laki during which volatiles reached the stratosphere. In Schmidt et al. [2012] in section 2, we argued in agreement with Cole-Dai et al. [2014] (section 3.1) that for a MIF anomaly to be preserved, the Laki volatiles would have had to be emitted in >20 km altitude. Our main point is that eruption column heights >20 km are unlikely based on the historical accounts and plume-rise modeling for the Laki eruption [Stothers et al., 1986; Woods, 1993; Thordarson and Self, 2003]. In Schmidt et al. [2012], we argued that to deduce a short-lived climatic impact of the Laki eruption based on the lack of a MIF anomaly and the length of the sulfate deposition in Greenland ice cores may be misleading because the climatic impact will outlast the radiative forcing of the Laki aerosol cloud. Cole-Dai et al. [2014] acknowledge the latter in their reply in section 4.2. We agreewith Cole-Dai et al. [2014] in that themagnitude and length of the climatic impact during the winter of 1783-1784 depends on the altitude of the volatile release during the eruption (sections 2.3 and 4.2). However, even if we assumed that during Laki all sulfur dioxide (SO2) would have been released in the troposphere, then the aerosol cloud would still be present in the upper troposphere during March 1784, as is evident from independent model simulations of this "tropospheric

  4. Tendances Carbone no. 77 'Low-carbon innovation is up, but not because of the EU ETS'

    International Nuclear Information System (INIS)

    Calel, Raphael; Dechezlepretre, Antoine

    2013-01-01

    Among the publications of CDC Climat Research, 'Tendances Carbone' bulletin specifically studies the developments of the European market for CO 2 allowances. This issue addresses the following points: The EU ETS is the main instrument of European climate policy, and many policy-makers envisage it as a driving force of the EU's transition to a low-carbon economy. By putting a price on emissions, the scheme is expected to encourage heavy polluters to develop new low-carbon technologies. At first glance it is encouraging to notice, then, that patenting for low-carbon technologies has surged in Europe since 2005. When analysing new data we find compelling evidence that the EU ETS has indeed encouraged regulated companies to develop new low-carbon technologies, but this effect is concentrated among too few companies to account for the surge in low-carbon patenting

    Primarily, to assess the performance of three statistical models in predicting successful vaginal birth in patients attempting a trial of labour after one previous lower segment caesarean section (TOLAC). The statistically most reliable models were subsequently subjected to validation testing in a local antenatal population. A retrospective observational study was performed with study data collected from the Northern Ireland Maternity Service Database (NIMATs). The study population included all women that underwent a TOLAC (n=385) from 2010 to 2012 in a regional UK obstetric unit. Data was collected from the Northern Ireland Maternity Service Database (NIMATs). Area under the curve (AUC) and correlation analysis was performed. Of the three prediction models evaluated, AUC calculations for the Smith et al., Grobman et al. and Troyer and Parisi Models were 0.74, 0.72 and 0.65, respectively. Using the Smith et al. model, 52% of women had a low risk of caesarean section (CS) (predicted VBAC >72%) and 20% had a high risk of CS (predicted VBAC <60%), of whom 20% and 63% had delivery by CS. The fit between observed and predicted outcome in this study cohort using the Smith et al. and Grobman et al. models were greatest (Chi-square test, p=0.228 and 0.904), validating both within the population. The Smith et al. and Grobman et al. models could potentially be utilized within the UK to provide women with an informed choice when deciding on mode of delivery after a previous CS.

    Notopterol, isoimperatorin, volatile oil and extract (water and ethanol) were used as the research objects in this study to investigate the effects of different softening method, slice thickness and drying methods on the quality of Notopterygii Rhizoma et Radix slices, and the experimental data were analyzed by homogeneous distance evaluation method. The results showed that different softening, cutting and drying processes could affect the content of five components in Notopterygii Rhizoma et Radix incisum. The best processing technology of Notopterygii Rhizoma et Radix slices was as follows: non-medicinal parts were removed; mildewed and rot as well as moth-eaten parts were removed; washed by the flowing drinking water; stacked in the drug pool; moistening method was used for softening, where 1/8 volume of water was sprayed for every 1 kg of herbs every 2 h; upper part of herbs covered with clean and moist cotton, and cut into thick slices (2-4 mm) after 12 h moistening until appropriate softness, then received blast drying for 4 h at 50 ℃, and turned over for 2 times during the drying. The process is practical and provides the experimental basis for the standardization of the processing of Notopterygii Rhizoma et Radix, with great significance to improve the quality of Notopterygii Rhizoma et Radix slices.

    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

    Ethyl Glucoronide (EtG) and Ethyl Sulfate (EtS) have shown promise as biomarkers for alcohol and may be sensitive enough for use with pregnant women in whom even low-level alcohol use is important. However, there have been reports of over-sensitivity of EtG and EtS to incidental exposure to sources such as alcohol-based hand sanitizer. Further, few studies have evaluated these biomarkers among pregnant women, in whom the dynamics of these metabolites may differ. This study evaluated whether commercial EtG-EtS testing was vulnerable to high levels of environmental exposure to alcohol in pregnant women. Two separate samples of five nurses-one pregnant and the other postpartum, all of whom reported high levels of alcohol-based hand sanitizer use-provided urine samples before and 4-8 hours after rinsing with alcohol-based mouthwash and using hand sanitizer. The five pregnant nurses provided urine samples before, during, and after an 8-hour nursing shift, during which they repeatedly cleansed with alcohol-based hand sanitizer (mean 33.8 uses). The five postpartum nurses used hand sanitizer repeatedly between baseline and follow-up urine samples. No urine samples were positive for EtG-EtS at baseline or follow-up, despite use of mouthwash and-in the pregnant sample-heavy use of hand sanitizer (mean of 33.8 uses) throughout the 8-hour shift. Current, commercially available EtG-EtS testing does not appear vulnerable to even heavy exposure to incidental sources of alcohol among pregnant and postpartum women.

    Full Text Available L’article propose une étude de genèse du chapitre 7 de Bouvard et Pécuchet, consacré à l’amour, qui forme une étape encyclopédique a priori un peu surprenante. Flaubert s’amuse à écrire ces aventures de Bouvard et Pécuchet, dans un pays qui n’est pas si tendre. L’étude de genèse porte sur le travail de l’écriture de plusieurs temps forts du chapitre (dans l’incipit, et les scènes de duos, notamment la scène entre Mme Castillon et Gorgu. Elle permet de montrer l’effacement de détails érotiques, mais aussi du politique et de l’histoire, qui se trouvent condensés dans le texte final. Elle révèle aussi le rôle concerté de ce chapitre dans la construction du roman et l’itinéraire des personnages. Anodin en apparence, ce chapitre est emblématique d’une poétique fondée sur l’ellipse, et qui mêle le jeu et le sérieux.This article presents a textual genetics study of Bouvard et Pécuchet’s 7th chapter, about love, which appears to be a surprising encyclopedic stage of the novel. Flaubert has fun writing these adventures in a not so tender country. This genetics study focuses on the writing of several key moments of the chapter (in the beginning and the duo scenes, such as the one between Mme Castillon and Gorgu. It reveals the erasure of erotic details, as well as politics and history, which end up condensed in the final text. It also shows this chapter’s concerted role in the construction of the novel and the characters’ development. Apparently minor, this chapter is emblematic of a poetics founded on the ellipsis, mingling play and seriousness.

    2007-05-15

    Ensuring energy security and addressing climate change issues in a cost-effective way are the main challenges of energy policies and in the longer term will be solved only through technology cooperation. To encourage collaborative efforts to meet these energy challenges, the IEA created a legal contract - Implementing Agreement - and a system of standard rules and regulations. This allows interested member and non-member governments or other organisations to pool resources and to foster the research, development and deployment of particular technologies. For more than 30 years, this international technology collaboration has been a fundamental building block in facilitating progress of new or improved energy technologies. There are now 41 Implementing Agreements. This is the third in the series of publications highlighting the recent results and achievements of the IEA Implementing Agreements. This document is arranged in the following sections: Cross-cutting activities (sub-sectioned: Climate technology initiative; Energy Technology Data Eexchange; and Energy technology systems analysis programme); End-use technologies (sub-sectioned: Buildings; Electricity; Industry; and Transport; Fossil fuels (sub-sectioned: Clean Coal Centre; Enhanced oil recovery Fluidized bed conversion; Greenhouse Gas R & D; Multiphase flow sciences); Fusion power; Renewable energies and hydrogen; and For more information (including detail on the IEA energy technology network; IEA Secretariat Implementing Agreement support; and IEA framework. Addresses are given for the Implementing Agreements. The publication is based on core input from the Implementing Agreement Executive Committee.

    2012-02-01

    Full Text Available A growing literature suggests that there is a disjuncture between the instructional practices of the education system and the student body it is expected to serve, particularly with respect to the roles of digital technologies. Based on surveys and focus group interviews of first-year students at a primarily undergraduate Canadian university and focus group interviews of professors at the same institution, this study explores the gaps and intersections between students’ uses and expectations for digital technologies while learning inside the classroom and socializing outside the classroom, and the instructional uses, expectations and concerns of their professors. It concludes with recommendations for uses of digital technologies that go beyond information transmission, the need for extended pedagogical discussions to harness the learning potentials of digital technologies, and for pedagogies that embrace the social construction of knowledge as well as individual acquisition. Des études de plus en plus nombreuses suggèrent qu’il existe un écart entre les pratiques d’enseignement dans le système de l’éducation et la population étudiante desservie, notamment en ce qui concerne le rôle des technologies numériques.

    2008-04-01

    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.

  15. Evaluating a technology supported interactive response system during the laboratory section of a histology course.

    Rinaldi, Vera D; Lorr, Nancy A; Williams, Kimberly

    2017-07-01

    Monitoring of student learning through systematic formative assessment is important for adjusting pedagogical strategies. However, traditional formative assessments, such as quizzes and written assignments, may not be sufficiently timely for making adjustments to a learning process. Technology supported formative assessment tools assess student knowledge, allow for immediate feedback, facilitate classroom dialogues, and have the potential to modify student learning strategies. As an attempt to integrate technology supported formative assessment in the laboratory section of an upper-level histology course, the interactive application Learning Catalytics TM , a cloud-based assessment system, was used. This study conducted during the 2015 Histology courses at Cornell University concluded that this application is helpful for identifying student misconceptions "on-the-go," engaging otherwise marginalized students, and forming a new communication venue between students and instructors. There was no overall difference between grades from topics that used the application and grades from those that did not, and students reported that it only slightly helped improve their understanding of the topic (3.8 ± 0.99 on a five-point Likert scale). However, they highly recommended using it (4.2 ± 0.71). The major limitation was regarding the image display and graphical resolution of this application. Even though students embrace the use of technology, 39% reported benefits of having the traditional light microscope available. This cohort of students led instructors to conclude that the newest tools are not always better, but rather can complement traditional instruction methods.

    2002-01-01

    Electron-impact differential cross-section measurements for the excitation of the 2p 5 3s configuration of Ne are reported. The Ne cross sections are obtained using experimental differential cross sections for the electron-impact excitation of the n=2 levels of atomic hydrogen [Khakoo et al., Phys. Rev. A 61, 012701-1 (1999)], and existing experimental helium differential cross-section measurements, as calibration standards. These calibration measurements were made using the method of gas mixtures (Ne and H followed by Ne and He), in which the gas beam profiles of the mixed gases are found to be the same within our experimental errors. We also present results from calculations of these differential cross sections using the R-matrix and unitarized first-order many-body theory, the distorted-wave Born approximation, and relativistic distorted-wave methods. Comparison with available experimental differential cross sections and differential cross-section ratios is also presented

  6. Roles and responsibilities of the special-section editor

    KAUST Repository

    Marfurt, Kurt

    2017-10-19

    Interpretation differs from most journals in that each issue is built largely on special sections that focus on integrated multidisciplinary approaches, techniques in exploration and production, on a specific technology, on a specific basin, or on a specific type of geologic process or feature common to multiple basins. Such special sections provide the reader with the perspective and expertise of authors from different institutions and disciplines focused on the same problem. Depending on the topic, the resulting collection of papers may exhibit diversity, consensus, or both. While the editorial board of a given journal may be able to identify a subset of candidate topics for special sections, in-depth knowledge of critical problems and of the key players working on such topics is usually beyond their areas of expertise. To address this need, Interpretation draws upon such experts to construct most special sections. In addition to providing a focused collection of articles on a given topic, there are two additional advantages of the special-section format. First, the journal broadens the scope of contributors beyond those whose career advancement (typically in academia and in government laboratories) requires them to publish in peer-reviewed journals. Typically, the special-section organizers will identify oral presentations and expanded abstracts presented at meetings (such as SEG, AAPG, URTeC, OTC, and SPE) and ask the authors to expand upon their work and generate a more comprehensive document. Apart from a few technology companies, most companies do not use external publications as a component of career development. For this reason, requests by a respected special editorial team provides not only recognition to the authors, but also the justification of the authors’ management to allow them to build on their work. Nearly all companies include the act of supporting communities among their core values. Contributing to a special section is a great way for

    2017-01-01

    Full Text Available Water environment capacity calculation is the foundation of basin environment management. Due to lack of basic materials and data, the water environment capacity in small basin was not massively researched with appropriate calculating method. This paper mentioned a water capacity calculating method suitable for environment management. The method was based on the study of Xuchang Section of Qingyi River and described with details as follows: Xuchang Section was divided into four control units with GIS technology. The river pollution loads of non-point source pollutants from farmland runoff, rural life, livestock and poultry were calculated with the in-site and statistical data of pollution resource. Meanwhile the calculated river pollution loads of non-point / point source pollutants were statistically analyzed on the basis of control units. Then a water quality module was tested and verified, in which the predicted value tallied with the measured value. The parameter of this water quality module corresponds to the in-site data within relative error ±14%. This module was used to estimate and calculate water environment capacity. With this module the available water environment capacity of each control unit and pollutant reduction amount can be earned through deducting the river pollutant load of point pollutant. The results showed that the utilized method in this paper can satisfy the requirement for the calculating accuracy of small basin water environment capacity.

    To explore and describe how persons with an acquired brain injury (ABI) managed the everyday technology (ET) that they needed to use in their workplace and how this use influences their opportunities to work. Nine persons with an ABI were interviewed and observed when managing ET in their workplace. The data were analysed qualitatively with a constant comparative method. The main category, "The challenge of managing ET in the workplace", consisted of three categories, all of which reflected different kinds of discrepancies between the participants' ability to manage ET and the demands that ET imposes on them in work: "Struggling with ET to be able to continue to work; "Depending on strategies to cope with ET to continue in a particular profession", and "Managing ET at work but concerned about keeping up with the changes". The result revealed discrepancies between the abilities of the persons with ABI to manage ET in relation to the demands that technology imposed on them in their work setting. This indicated that professionals need to consider the role of ET when designing interventions supporting a person's return to work after an ABI.

    Full Text Available Le « Nez électronique », et plus récemment la « Langue électronique » ont été fort médiatisés durant la dernière décennie. Aussi est-il nécessaire, avec le recul, de faire le point sur les bénéfices que ces technologies peuvent apporter dans le domaine des produits alimentaires, et en particulier pour huiles végétales. On trouve une littérature relativement abondante dans ce domaine, mais les applications qui ont réussi à franchir le cap de l’utilisation industrielle sont extrêmement restreintes. S’agit-il d’une frilosité des industriels pour des investissements de contrôle-qualité ou d’un manque de fiabilité des résultats de laboratoire ? Pourtant, la demande en outils rapides de contrôle-qualité (ou de contrôle d’origine n’a jamais été aussi pressante. Nous expliquerons ce point par la nature même du produit, principalement pour l’huile d’olive extra vierge. D’autres techniques faisant appel à l’enrichissement en composés volatils seront introduites, laissant espérer à l’avenir une amélioration de la fiabilité des analyses.

  18. Converting point-wise nuclear cross sections to pole representation using regularized vector fitting

    2018-03-01

    Direct Doppler broadening of nuclear cross sections in Monte Carlo codes has been widely sought for coupled reactor simulations. One recent approach proposed analytical broadening using a pole representation of the commonly used resonance models and the introduction of a local windowing scheme to improve performance (Hwang, 1987; Forget et al., 2014; Josey et al., 2015, 2016). This pole representation has been achieved in the past by converting resonance parameters in the evaluation nuclear data library into poles and residues. However, cross sections of some isotopes are only provided as point-wise data in ENDF/B-VII.1 library. To convert these isotopes to pole representation, a recent approach has been proposed using the relaxed vector fitting (RVF) algorithm (Gustavsen and Semlyen, 1999; Gustavsen, 2006; Liu et al., 2018). This approach however needs to specify ahead of time the number of poles. This article addresses this issue by adding a poles and residues filtering step to the RVF procedure. This regularized VF (ReV-Fit) algorithm is shown to efficiently converge the poles close to the physical ones, eliminating most of the superfluous poles, and thus enabling the conversion of point-wise nuclear cross sections.

  1. Energy-efficient technology in the iron and steel industry: Simulation of new technology adoption with items

    International Nuclear Information System (INIS)

    Roop, J.M.

    1997-01-01

    The Industrial Technology and Energy Modeling System (ITEMS)(referred to as ISTUM in Jaccard and Roop, 1990) is an end-use industrial modeling system that is technology based. Because it includes technologies in the process description of industry, it is possible to introduce new technologies to determine, based on economic and performance data, how rapidly these new technologies will penetrate the market (Hyman and Roop, 1996). As these new technologies penetrate the market, energy savings and, possibly, emissions reductions occur that can be tracked with the model as well. This report documents the use of ITEMS to investigate the impact of three new technologies under development with funding from the Department of Energy's Office of Industrial Technologies (OIT), that apply to the iron and steel industry. While the results of this application are interesting, this exercise points out how important it is to understand how the technologies work and how they make a difference. This report shows that ITEMS can be a useful tool in estimating market penetration of new technologies and the resulting energy savings, but these results are only as reliable as the data. If the model is to be used to compare technologies, the technical data concerning these technologies must be collected using the same set of assumptions and with the same vision of what characterizes a technology. While an effort has been made to understand how these technologies work, there is no assurance that the data used for this analysis were, indeed, collected using the same vision and the same set of assumptions. The report is organized into five additional sections. The next provides a brief overview of ITEMS and describes how the technical information about OIT projects is used in the model. The third section describes the three technologies that were introduced into ITEMS and reports the relevant data for those projects. The fourth section describes the iron and steel industry, as characterized

    of advanced CSCW technologies is basically a problem of sensemaking. We analyze how a group of “technology-use mediators” (Orlikowski et al. Org. Sci. (1995) 6(4), 423) in a large, multinational company adapted a groupware technology (a “virtual workspace”) to the local organizational context (and vice versa......) by modifying features of the technology, providing ongoing support for users, and promoting appropriate conventions of use. Our findings corroborate earlier research on technology-use mediation, which suggests that such mediators can exert considerable influence on how a particular technology...... will be established and used in an organization. However, we also find that the process of technology-use mediation is much more complex and indeterminate than prior research suggests. The reason being, we argue, that new, advanced CSCW technologies, such as “virtual workspaces” and other groupware applications...

    2012-08-01

    Restoring the ability to communicate and interact with the environment in patients with severe motor disabilities is a vision that has been the main catalyst of early brain-computer interface (BCI) research. The past decade has brought a diversification of the field. BCIs have been examined as a tool for motor rehabilitation and their benefit in non-medical applications such as mental-state monitoring for improved human-computer interaction and gaming has been confirmed. At the same time, the weaknesses of some approaches have been pointed out. One of these weaknesses is gaze-dependence, that is, the requirement that the user of a BCI system voluntarily directs his or her eye gaze towards a visual target in order to efficiently operate a BCI. This not only contradicts the main doctrine of BCI research, namely that BCIs should be independent of muscle activity, but it can also limit its real-world applicability both in clinical and non-medical settings. It is only in a scenario devoid of any motor activity that a BCI solution is without alternative. Gaze-dependencies have surfaced at two different points in the BCI loop. Firstly, a BCI that relies on visual stimulation may require users to fixate on the target location. Secondly, feedback is often presented visually, which implies that the user may have to move his or her eyes in order to perceive the feedback. This special section was borne out of a BCI workshop on gaze-independent BCIs held at the 2011 Society for Applied Neurosciences (SAN) Conference and has then been extended with additional contributions from other research groups. It compiles experimental and methodological work that aims toward gaze-independent communication and mental-state monitoring. Riccio et al review the current state-of-the-art in research on gaze-independent BCIs [1].

However, when a part of the research work can be clearly identified as an R D activity aimed at the development of a new technology or procedure for specific, or a more general, application it is worthwhile to cut it off and manage it as an independent self-consistent experiment. For many of them it is also easy to find applications in other research discipline or industry. In this case it is important to verify the potentiality of the technology, customize it and improve it, in collaboration with the end user, for the specific application.

  2. Mid-rapidity pion cross sections: new data confront theories

    International Nuclear Information System (INIS)

    Frankel, K.A.; Bistirlich, J.A.; Bossingham, R.

    1981-07-01

    Pion production by collisions of relativistic heavy ions has been studied recently by Wolf et al. For the reaction 1.05 GeV/A 40 Ar + Ca → π + , they discovered a peak in the invariant cross section at mid-rapidity at P/sub perpendicular/ approx. 0.5 m/sub π/c. This peak is not apparent in the 730 MeV p + p data of Cochran et al. and was attributed to possible hydrodynamic flow effects. Several authors have suggested that the π + peak is a Coulomb effect. These models predict the π - would be drawn in towards the fireball, leaving an essentially flat distribution in the mid-rapidity region. Mid-rapidity π + and π - cross sections were measured using a 1.05 GeV/A argon beam with a calcium target. The pions were measured with a magnetic spectrometer set at 15 0 to the beam and were stopped in a scintillator range telescope. Results are presented and discussed

  3. Measurements of Positronium Formation Cross Sections for Positron-Kr, Xe Scattering

    Science.gov (United States)

    Kauppila, W. E.; Kwan, C. K.; Li, H.; Stein, T. S.; Zhou, S.

    1997-04-01

    Our experimental approach(S. Zhou et al., Phys. Rev. Lett. 73, 236 (1994).) for measuring Ps formation cross sections (Q_Ps) involves passing a variable energy positron beam through a gas scattering cell and detecting the 511 keV annihilation gamma rays resulting from the decay of para-Ps and from the interaction of ortho-Ps with the walls of the scattering cell. It is found that the Q_Ps curves for both Kr and Xe rise rapidly from their formation threshold energies of 7.2 and 5.3 eV, reach maxima within about 10 eV of their thresholds and then decrease to become rather small (less than 10% of the peak heights) above 100 eV. At the maxima Q_Ps accounts for more than 50% of the total scattering cross sections. There is some evidence of possible small scale structure in the Q_Ps curves between 10 and 100 eV. The present results are consistent with the prior measurements of Diana et al.( L.M. Diana et al., in "Atomic Physics with Positrons", edited by J.W. Humberston and E.A.G. Armour (Plenum, New York and London, 1987), p. 55; and in "Positron Annihilation", edited by L. Dorikens-Vanpraet et al.

    Full Text Available L’article présente les résultats d’une recherche portant sur les notions d’entrepreneur social et d’entrepreneur collectif. Après avoir défini le concept d’entrepreneur, nous voyons comment les qualitatifs « social » et « collectif » transforment l’idée d’entreprendre en un projet plus intégré où les objectifs sociaux, politiques et économiques sont « harmonieusement » agencés. La recherche repose essentiellement sur la réalisation d’une revue de littérature de textes clés produits en langue française et anglaise en Amérique du Nord et en Europe. L’analyse des données recueillies nous permet de présenter des critères simples pour proposer une définition de ces notions qui devrait rendre compte de la réalité des pratiques rencontrées sur le terrain et des contributions théoriques et critiques faites par les auteurs et travaux consultés. Elle permet aussi de présenter une dizaine de constats qui illustrent tant les points de convergence que les divergences observées entre les types d’entreprenariat étudiés. / This article presents the results of a study bearing on the notions of social entrepreneur and collective entrepreneur. After defining the concept of entrepreneur, I look at how the adjectives “social” and “collective” transform the project of being an entrepreneur into a more integrated one where the social, political and economic objectives are “harmoniously” organized. The study is essentially based on a literature review of key English- and French-language texts written in North America and in Europe. The analysis of the collected data allows me to present simple criteria for proposing a definition of these notions that should take into account both the reality of the practices encountered in the field and the theoretical and critical contributions made by the authors and the texts that I consulted. It also enables me to present ten observations that illustrate both the

  9. Geologic Mapping and Paired Geochemical-Paleomagnetic Sampling of Reference Sections in the Grande Ronde Basalt: An Example from the Bingen Section, Columbia River Gorge, Washington

    Science.gov (United States)

    Sawlan, M.; Hagstrum, J. T.; Wells, R. E.

    2011-12-01

    We have completed comprehensive geochemical (GC) and paleomagnetic (PM) sampling of individual lava flows from eight reference stratigraphic sections in the Grande Ronde Basalt (GRB), Columbia River Basalt Group [Hagstrum et al., 2009, GSA Ann. Mtg, Portland (abst); Hagstrum et al., 2010, AGU Fall Mtg, San Francisco (abst)]. These sections, distributed across the Columbia Plateau and eastern Columbia River Gorge, contain as many as 30 flows, are up to 670 m thick, span upper magneto-stratigraphic zones R2 and N2, and, in some locations, also contain one or more N1 flows. In concert with GC and PM sampling, we have carried out detailed geologic mapping of these sections, typically at a scale of 1:3,000 to 1:5,000, using GPS, digital imagery from the National Aerial Imagery Program (NAIP), and compilation in GIS. GRB member and informal unit names of Reidel et al. [1989, GSA Sp. Paper 239] generally have been adopted, although two new units are identified and named within the N2 zone. Notably, a distinctive PM direction for intercalated lavas of several lower N2 units indicates coeval eruption of compositionally distinct units; this result contrasts with the scenario of serial stratigraphic succession of GRB units proposed by Reidel et al. [1989]. Our objectives in the mapping include: Confirming the integrity of the stratigraphic sequences by documenting flow contacts and intraflow horizons (changes in joint patterns or vesicularity); assessing fault displacements; and, establishing precisely located samples in geologic context such that selected sites can be unambiguously reoccupied. A geologic map and GC-PM data for the Bingen section, along the north side of the Columbia River, are presented as an example of our GRB reference section mapping and sampling. One of our thicker sections (670 m) along which 30 flows are mapped, the Bingen section spans 7 km along WA State Hwy 14, from near the Hood River Bridge ESE to Locke Lake. This section cuts obliquely through a

    Technology has not only become an integral part of people’s lives but also of people’s everyday struggles. Struggles with technology are complex in nature; we tend to not only struggle with their basic functions but also with how they make us feel. During the course of our life we tend to master...... and struggle with technology in different ways. This struggle has been studied in relation to media literacy (Livingstone, 2004), to domestication theory (Silverstone et al. 1992), or in everyday life (Bakardjieva, 2005). This work enhances these lines of studies by exploring everyday struggles with technology...... from a life stage (Erikson, 1959) point of view. In particular, we explore what are common struggles people have with technology and what are distinct struggles in relation to life stages. In conclusion, we will present our findings by outlining what we call ‘technological biographies’. Those...

    The primary objective of the Heavy Section Steel Technology (HSST) Program is to develop pertinent fracture technology to demonstrate the structural reliability of present and contemplated water-cooled nuclear reactor pressure vessels. In order to demonstrate the ability to predict failure of large, heavy-walled pressure vessels under service type loading conditions, the fracture toughness properties of the vessel's materials must be characterized. The sampling procedure and test results are presented for vessel material supplied by the Oak Ridge National Laboratory that were used to characterize the fracture toughness of the HSST Intermediate Test Vessels. The metallurgical condition and heat treatment of the test material was representative of the vessel simulated service test condition. Test specimen locations and orientations were selected by the Oak Ridge National Laboratory and are representative of flaw orientations incorporated in the test vessels. The fracture toughness is documented for the materials from each of the eight HSST Intermediate Pressure Vessels tested to date. 7 references. (U.S.)

A critique of objectification in instructional technology is presented. In the context of Heidegger’s critique of technology, the authors claim that objectification in education is metaphysical in the sense that the intelligibility (being of education is equated with ready-to-use packages, and thus is reduced to delivery and transmission of objects. The embodiment dimension of teaching and learning can help us in resisting this reduction. The authors argue that objectification increases bureaucratic control over the teaching process and deskills teachers; and by which teachers are proletarianized. The authors conclude that instructional designers should create structures in which a care relation and dialogue between students and teachers can take place.

  9. Double- and triple-differential cross sections for electron-impact ionization of helium

    International Nuclear Information System (INIS)

    Biswas, R.; Sinha, C.

    1995-01-01

    Triple- (TDCS) and double- (DDCS) differential cross sections have been calculated for single ionization in electron-helium collisions for asymmetric geometry at intermediate and medium high energies. The TDCS and DDCS results have been presented for different kinematical situations and have been compared with the corresponding experiments. In the present prescription, the final-state wave function involves the correlation between the two continuum electrons and satisfies the three-body asymptotic boundary condition (for asymmetric geometry), which is an important criterion for reliable ionization cross sections. The sensitivity of the ionization cross sections (particularly of the TDCS) with respect to the choice of the bound-state wave function of the He atom has also been studied, using two different forms of wave function of the He atom. The binary-to-recoil peak intensity ratio against momentum transfer in TDCS is found to be in closer agreement with the experiment for the simple Hylleraas wave function than for the Hartree-Fock wave function. The DDCS results are found to be in good agreement with the experimental data of Mueller-Fiedler et al. [J. Phys. B 19, 1211 (1986)] for lower ejected energy (E 2 ), while for higher E 2 the results are closer to the measurements of Shyn et al. [Phys. Rev. A 19, 557 (1979)] and Avaldi et al.

  10. A project-based system for including farmers in the EU ETS.

    Science.gov (United States)

    Brandt, Urs Steiner; Svendsen, Gert Tinggaard

    2011-04-01

    Farmers in the EU do not trade greenhouse gases under the Kyoto agreement. This is an empirical puzzle because agriculture is a significant contributor of greenhouse gases (GHG) in the EU and may harvest private net gains from trade. Furthermore, the US has strongly advocated land-use practices as 'the missing link' in past climate negotiations. We argue that farmers have relatively low marginal reduction costs and that consequences in terms of the effect on permit price and technology are overall positive in the EU Emission Trading System (ETS). Thus, we propose a project-based system for including the farming practices in the EU ETS that reduces the uncertainty from measuring emission reduction in this sector. The system encourages GHG reduction either by introducing a new and less polluting practice or by reducing the polluting activity. When doing so, farmers will receive GHG permits corresponding to the amount of reduction which can be stored for later use or sold in the EU ETS. Copyright © 2010 Elsevier Ltd. All rights reserved.

    2000-01-01

    Electron-impact absolute emission cross sections were measured for the 3p→3s transitions of Ne. Excitation functions of the 3s→2p first resonance lines were measured in the energy range from the threshold to 1000 eV by a polarization-free optical method and relative cross sections were normalized to the absolute values, (41.0±5.4)x10 -19 cm 2 for the 73.6 nm line and (7.1±1.0)x10 -19 cm 2 for the 74.4 nm line, which were determined at 500 eV. The integrated level-excitation cross sections of Suzuki et al for the 1s 2 and 1s 4 levels were combined with the corresponding 3p→3s cascade cross sections obtained in this paper to give absolute emission cross sections for the resonance lines. The level-excitation cross sections of the 1s 2 and 1s 4 states in Paschen notation were determined from the threshold to 1000 eV by subtracting 3p→3s cascade cross sections from the corresponding 3s→2p emission cross sections of the resonance lines. A large cascade contribution is found in the emission cross section of the resonance lines. It is 28.5% for the 73.6 nm line and 49.6% for the 74.4 nm line at 40 eV, and 17.0 and 61.8%, respectively, at 300 eV. (author)

    New media technologies (computers, mobile phones and the internet) have the potential to transform the healthcare information needs of patients with breast disease (Ferlay et al. in Eur J Cancer 49:1374-1403, 2013). However, patients' current level of use and their willingness to accept new media for education and communication remain unknown. This was a single-centre clinic-based prospective cross-sectional study. A previously developed instrument was modified, validated and tested on patients attending a symptomatic breast clinic. The instrument was evaluated on 200 symptomatic breast patients. The commonest outlets for education were staff (95 %), leaflets (69 %) and websites (59 %). Websites are more likely to be consulted by younger patients (higher education were more likely to favour apps, websites and email (p technology use among breast patients is expanding as expected along generational trends. As such its' further integration into healthcare systems can potentially ameliorate patient education and communication.

  17. Higher energy dissociative electron attachment cross sections in sulfur dioxide

    Kurepa, M.; Pejcev, V.; Cadez, I.

    2000-01-01

    Experimental results of total electron attachment cross sections are presented with, for comparison, two additional sets of data, those of Orient and Srivastava and of Spyrou et al.. Both were normalized to present values of the first attachment peak at 4,6 eV, in order to show more clearly differences in cross section curve shapes. In fact, data of Orient and Srivastava are larger that the present ones for a factor of 2,82; while those of Spyrou et al. are higher only for 3,70 %. Both these sets of data, as well as those by Cadez et al., cover an incident electron energy range 3,40 - 9,40 eV. Electron attachment processes at energies higher that 9,40 eV have been in fact detected and measured in the same set of experiments that led to former publication of lower energy attachment processes by Cadez et al.. At that time in none of experiments, that could distinguished ionic species formed in dissociation attachment processes, was a sign of ions at incident electron energies exceeding 9,40 eV. That caused our ignorance toward processes detected and measured at higher incident electron energies, mainly since they were at least one order of magnitude lower that the two peaks at 4,6 eV and 7,3 eV, respectively. Without additional experiments, that include mass analysis of ionic species formed in dissociative electron attachment processes, it is not possible to give any sound explanation to causes of peaks at energies higher that 8,0 eV

  19. A Low Cost Air Hybrid Concept Un concept hybride à air et à bas prix

    Directory of Open Access Journals (Sweden)

    2010-02-01

    Full Text Available The air hybrid engine absorbs the vehicle kinetic energy during braking, stores it in an air tank in the form of compressed air, and reuses it to propel a vehicle during cruising and acceleration. Capturing, storing and reusing this braking energy to give additional power can therefore improve fuel economy, particularly in cities and urban areas where the traffic conditions involve many stops and starts. In order to reuse the residual kinetic energy, the vehicle operation consists of 3 basic modes, i.e. Compression Mode (CM, Expander Mode (EM and normal firing mode. Unlike previous works, a low cost air hybrid engine has been proposed and studied. The hybrid engine operation can be realized by means of production technologies, such as VVT and valve deactivation. In this work, systematic investigation has been carried out on the performance of the hybrid engine concept through detailed gas dynamic modelling using Ricardo WAVE software. Valve timing optimization has been done for the more efficient operation of air hybrid operation and obtaining higher braking and motoring mean effective pressure for CM and EM respectively. Le moteur hybride à air absorbe l’énergie cinétique du véhicule en cas de freinage, la stocke sous forme d’air comprimé, puis la réutilise pour faire avancer le véhicule en circulation ou en accélération. Capter, stocker et réutiliser cette énergie et créer ainsi une puissance plus importante peut donc permettre de plus grandes économies de carburant, surtout en ville et zone urbaine, lorsque les conditions de circulation imposent de nombreux arrêts et démarrages. Pour pouvoir réutiliser l’énergie cinétique, on distingue trois modes de base d’utilisation du véhicule : les modes compression (MC, expansion (ME et standard. Un moteur hybride à air et à bas prix a été proposé et étudié. Un tel moteur peut être opéré par le biais de technologies de production, comme le VVT et la d

    A hydrodynamic model of a region of Yaregskoye heavy oilfield was build. The results of the simulation have shown that injection capacity along the wellbore of a horizontal well is not uniform. It is determined by the geological heterogeneity of the formation. Therefore, there is importance of enhancing SAGD technology for Yaregskoye oilfield. A new technology was created. The efficiency of the technology is proved by numerical modelling. Horizontal injector and two-wellhead production wells penetrate the formation. Horizontal sections of the wells are located one above the other in the payzone. Wells are divided into two sections. Those sections work simultaneously and independently of one another. This technology allows to increase oil recovery of the oilfield.

  5. Abundant spontaneous VLFE activities in Cascadia during ETS and inter-ETS time periods

    Ghosh, A.; Hutchison, A. A.; Hawthorne, J.

    Very low frequency earthquakes (VLFEs) are discrete seismic events associated with episodic tremor and slip (ETS) events. They are rich in 20-50s energy and depleted in higher frequencies compared to regular local earthquakes of similar magnitudes. VLFEs can be as large as Mw 4.0, and potentially release much more seismic moment than the tremor/LFE activities, making them a critical event determining stress evolution during slow earthquakes [Ghosh et al., 2015]. Their underlying physics and relationship with tremor/LFE, however, are still unclear. In Cascadia, the majority of the VLFEs found so far are clustered near the areas of high geodetic slip during ETS events [Ghosh et al., 2015; Hutchison and Ghosh, 2016]. Interestingly, we found VLFE activity has its own dynamics and can occur independent of tremor/LFE activity. For example, during the 2014 ETS event in northern Cascadia, VLFEs are found to be asynchronous with tremor activity, both in space and time [Hutchison and Ghosh, 2016]. We use a matched filter technique to detect thousands of VLFEs over an ETS-cycle, and perhaps more interestingly, even between ETS events. VLFE activities peak during ETS events, but significant VLFE activity is detected during the inter-ETS time period. Analyses of strainmeter data near the VLFE locations suggest statistically significant strain rate increases during VLFE time periods compared to the background. We suggest that VLFE is a distinct type of seismic radiation different from tremor/LFE, and can operate independently from tremor activities. This is in contrast to a model suggesting that VLFE signals may be a result of many LFE signals arriving at seismic stations in a short time period [Gomberg et al., 2016]. We are making a consistent catalog of VLFE in Cascadia for longer time period. Systematic study of VLFEs is going to provide new insights into the mechanism of slow earthquakes and its relationship with tremor/LFE and slow slip.

    Chronic kidney disease (CKD) is increasing worldwide and early education to improve adherence to self-management is a key strategy to slow CKD progression. The use of the internet and mobile phone technologies (mHealth) to support patients is considered an effective tool in many other chronic disease populations. While a number of mHealth platforms for CKD exist, few studies have investigated if and how this population use technology to engage in self-management. Using a cross-sectional design across five health districts in Queensland (Australia), a 38-item self-report survey was distributed to adults with CKD attending outpatient clinics or dialysis units to measure current use and type of engagement with mHealth, perceived barriers to use, and opportunities to support CKD self-management. Odds ratio (OR) were calculated to identify associations between demographic characteristic and mHealth use. Of the 708 participants surveyed, the majority had computer access (89.2%) and owned a mobile phone (83.5%). The most likely users of the internet were those aged ≤ 60 years (OR: 7.35, 95% confidence interval [CI]: 4.25-12.75, p higher levels of education (OR: 3.69, CI: 2.38-5.73, p mobile phone for complex communication were also younger (OR: 6.01, 95% CI: 3.55-10.19, p educated (OR: 1.99, 95% CI: 1.29-3.18, p technologies most preferred for communication with their renal healthcare teams were by telephone (56.5%), internet (50%), email (48.3%) and text messages (46%). In the CKD cohort, younger patients are more likely than older patients to use mHealth intensively and interactively although all patients' technology literacy ought to be thoroughly assessed by renal teams before implementing in practice. Further research testing mHealth interventions to improve self-management in a range of patient cohorts is warranted.

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

    Full Text Available Research does not indicate a consensus on the relationship between idiosyncratic volatility and asset returns. Moreover, the role of cross sectional higher order moments in predicting market returns is relatively unexplored. We show that the cross sectional volatility measure suggested by Garcia et al. is highly correlated with alternative measures of idiosyncratic volatility constructed as variance of errors from the capital asset pricing model and the Fama French model. We find that cross sectional moments help in predicting aggregate market returns in some sample countries and also provide information for portfolio formation, which is more consistent for portfolios sorted on sensitivity to cross sectional skewness.

  19. Total cross sections for electron scattering by He

    International Nuclear Information System (INIS)

    De Heer, F.J.; Jansen, R.H.J.

    1977-01-01

    A set of total cross sections for scattering of electrons by He has been evaluated over the energy range of zero to 3000 eV by means of the analysis of experiments and theories on total cross sections for elastic scattering, ionisation and excitation, and on differential cross sections for elastic and inelastic scattering. Between 0 and 19.8 eV, where no inelastic processes occur, the total cross sections for scattering are equal to those for elastic scattering. Above 19.8 eV total cross sections for scattering of electrons have been evaluated by adding those for ionisation, excitation and elastic scattering. The total cross sections thus obtained are probably accurate to about 5% over a large part of the energy range. They appear to be in very good agreement with the recent experimental results of Blaauw et al. (J. Phys. B.; 10:L299 (1977)). The present results have already proved useful for application in the dispersion relation for forward scattering in electron-helium collisions. (author)

  20. Cooling Effect of Evapotranspiration (ET) and ET Measurement by Thermal Remote Sensing in Urban

    Affected by global warming and rapid urbanization, urban thermal environment and livability are getting worse over the world. Global terrestrial evapotranspiration (ET) can annually consume 1.483 × 1023 joules of solar energy, which is about 300 times of the annual human energy use on the earth (4.935×1020 joules). This huge amount of energy use by ET indicates that there is great potential to cool the urban by regulating ET. However, accurately measurement of urban ET is quiet difficult because of the great spatial heterogeneity in urban. This study focuses on to quantify the cooling effects ET by mobile traverse method and improve a methodology to measure the urban ET by thermal remote sensing. The verifying experiment was carried out in Shenzhen, a sub-tropical mega city in China. Results showed that ET of vegetation could obviously reduce the urban temperature in hot season. Daily transpiration rate of a small-sized Ficus tree (Ficus microcarpa, 5 m in height and 20 cm of trunk diameter, measured by sap-flow method) was 36-55 kg and its cooling effect was equivalent to a 1.6-2.4 kWh air conditioner working for 24 hours. A 10% increase in the vegetated area could decrease urban temperature by 0.60°C at hot night. Moreover, it was found that a region with a vegetated area ratio over 55% had obvious effect on temperature decreasing. In addition, a methodology by using "thermal remote sensing + three-temperature model" was improved to measure the urban ET. Results showed that the urban ET could be reasonably measured by the proposed method. The daily ET of an urban lawn was 0.01-2.86 mm and monthly ET was 21-60 mm. This result agreed well with the verification study (Bowen ratio method, r=0.953). These results are very useful for urban planning, urban lower impact development, and improving of urban thermal environment.

    The present report summarizes the final results of the IAEA Co-ordinated Research Programme on ''Activation Cross Section for the Generator of Long-lived Radionuclides of Importance in Fusion Reactor Technology''. The goal of the CRP was to obtain reliable information (experimental and evaluated) for 16 long-lived activation reactions of special importance to fusion reactor technology. By limiting the scope of the CRP to just 16 reactions it was possible to establish a very effective focus to the joint effort of many laboratories that has led to the generation of a set of valuable new data which provide satisfactory answers to several questions of technological concern to fusion.

    2001-09-01

    The content concentrations of actinides are calculated as a function of operating reactor regime and cooling time at different percentage of fuel burn-up. The build-up transmutation equations of actinides content in an irradiated fuel are solved numerically .A computer code BAC was written to operate on a PC computer to provide the required calculations. The fuel element of 10% {sup 235}U enrichment of ET-RR-1 reactor was taken as an example for calculations using the BAC code. The results are compared with other calculations for the ET-RR-1 fuel rod. An estimation of fissile build-up content of a proposed new fuel of 20% {sup 235}U enrichment for ET-RR-1 reactor is given. The sensitivity coefficients of build-up plutonium concentrations as a function of cross-section data uncertainties are also calculated.

The chapters fo through the more promising technologies related to the diverse energy sources, from the nuclear to the renewable and chemical a large gamut of energy supply ways is revised. The analysis of the production technologies is accompanied by considerations of the environmental implications, an aspect to wich a whole part of the volume is devoted. The book begins with a foreword by Dr. Felix Yndurain, former General Director of CIEMAT and follows with a general introduction to the main topics, that are presented in three parts, with specific introductions. There is also a closing fourth part that includes some additional activities where more basic and technical developments are included. The first part is devoted to energy of nuclear origin. In two separate sections, fission and fusion technologies are covered. The fission section points towards the present day problems of nuclear plants (ageing, accidents, risk analysis, etc.), reprocessing of the nuclear fuel, radioactive wastes and environmental radioactivity. The fusion section contains a critical account of the present and expected developments of the fusion reactors together with an exposition of the related plasma physics problems. The second part comprises two sections devoted to energy generation of renewable and chemical origin, respectively. Tehcnologies for solar, wind and biomass energies are thoroughly exposed along the renewable energy section whereas the chemical energy section is devoted to the modern technologies of clean fossil fuel combustion and gasification, as well as to the new appealing subject of direct electric generation with fuel cells.

  13. The initial impact of EU ETS verification events on stock prices

    2016-01-01

    This paper studies the impact of verified emissions publications in the European Emissions Trading Scheme (EU ETS) on the market value of participating companies. Using event study methodology on a unique sample of 368 listed companies, we show that verified emissions only resulted in statistically significant market responses when the carbon price was high and allowance scarcity was anticipated. The cross-section analysis of abnormal returns surrounding the publication of verified emissions shows that share prices decrease when actual emissions relative to allocated emissions increase. This negative relationship between allocation shortfalls and firm value is only significant for firms that are either carbon-intensive, compared to sector peers, or are less likely to pass through carbon-related costs in their product prices. The results suggest that although the EU ETS has been deemed unsuccessful so far due to over-allocation and low carbon price, shareholders initially perceived allowance holdings as value relevant. Our results highlight that a significant carbon market price and addressing pass-through costing are essential for successful future reforms of the EU ETS and other analogous carbon cap-and-trade systems implemented or planned worldwide. - Highlights: •We study the impact of EU ETS verified emissions disclosure on firms' market value. •Disclosure is relevant if carbon price is high and permits scarcity is anticipated. •We find a negative relationship between allocation shortfalls and firm value. •Stronger relationship for carbon – intensive and no cost pass-through firms. •High carbon price and addressing cost pass-through are crucial for EU ETS reforms.

    Full Text Available L’adoption d’une technologie de l’information et de la communication (TIC pour la formation ne peut se faire sans changement dans l’organisation. Ces changements touchent les formateurs, hommes et femmes, qui ont une histoire professionnelle, une mentalité, des pratiques qui se sont construites au cours des années et dans un contexte précis de travail. Or les changements technologiques peuvent déstabiliser la vie professionnelle des formateurs. Il est donc essentiel de gérer ce changement, car le succès des projets d’introduction des TIC dans la formation n’est plus fonction de la puissance des technologies, mais plutôt de la capacité des formateurs à exploiter leur potentiel afin de changer et d’améliorer l’efficience du processus d’apprentissage. C’est dans un contexte d’implantation d’une formation des formateurs en ligne que se situe cet article qui aborde les questions suivantes : quels sont les obstacles au changement par rapport à l’adoption des TIC dans le milieu de la formation?

    We report differential cross sections (DCSs) and integral cross sections (ICSs) for electron-impact vibrational-excitation of pyrimidine, at incident electron energies in the range 15–50 eV. The scattered electron angular range for the DCS measurements was 15°–90°. The measurements at the DCS-level are the first to be reported for vibrational-excitation in pyrimidine via electron impact, while for the ICS we extend the results from the only previous condensed-phase study [P. L. Levesque, M. Michaud, and L. Sanche, J. Chem. Phys. 122, 094701 (2005)], for electron energies ⩽12 eV, to higher energies. Interestingly, the trend in the magnitude of the lower energy condensed-phase ICSs is much smaller when compared to the corresponding gas phase results. As there is no evidence for the existence of any shape-resonances, in the available pyrimidine total cross sections [Baek et al., Phys. Rev. A 88, 032702 (2013); Fuss et al., ibid. 88, 042702 (2013)], between 10 and 20 eV, this mismatch in absolute magnitude between the condensed-phase and gas-phase ICSs might be indicative for collective-behaviour effects in the condensed-phase results.

    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

  5. An anchored astronomical time-scale for the Turonian reference sections in the Umbria-Marche Basin, Italy

    2012-04-01

    In the Umbria-Marche basin, the aftermath of Ocean Anoxic Event 2 (OAE2, Bonarelli Level) is represented by the Turonian part of the Scaglia Rossa Formation. The Scaglia Rossa pelagic limestones were studied in the classic Contessa and Bottaccione sections near Gubbio, in the Umbria-Marche region of the northeastern Apennines of Italy. Oscillations between radiolarian cherts interbedded with foram-coccolith pelagic limestones are interpreted to follow the rhythm of precession and show hierarchical bundles, which are suggestive of eccentricity-related grouping. Eccentricity-bundles are correlated amongst the two studied sections. Moreover, the magnetic susceptibility signal of the Bottaccione section and the δ18O and δ13C record of both sections clearly demonstrate the imprint of precession and eccentricity. Eccentricity minima are associated with relatively warm periods (δ18O minima), characterized by an increased magnetic susceptibility signal and radiolarian blooms, which are expressed by frequent chert beds. Radiolarian blooms seem to hamper primary productivity, given that they correlate with δ13C minima. The delineated astronomical cycles constitute an eccentricity-based cyclostratigraphy for the Turonian part of the Scaglia Rossa. Moreover, the constructed cyclostratigraphy is anchored to numerical time by calibration with the astronomical solution La2010 (Laskar et al., 2011) and with recent radioisotopic ages from the Cenomanian-Turonian boundary interval near the GSSP in Colorado, USA (Meyers et al., 2012). The numerical age (93.9 ± 0.15 Ma; Meyers et al., 2012) of the Cenomanian-Turonian boundary (0.75 m above the top of the Bonarelli Level in the Contessa section; Tsikos et al., 2004; Kennedy et al., 2005) is used as the pinpoint to which our astronomical time-scale is anchored. Using the anchored astronomical time-scale for the Turonian of the Umbria-Marche basin, the top of the Bonarelli Level is placed at 93.97 ± 0.25 Ma, and the boundary

Tout cela représente le principal facteur des mutations sociales.De nouveaux modèles de déviance et de criminalité voient le jour au sein du cyberspace, de même que les groupes terroristes traditionnels emploient de manière intensive les nouveaux médias. Toutefois, il faudra faire tout particulièrement attention au phénomène qualifié de « Jihad Digitale ». Quel est le rôle des médias dans le terrorisme contemporain ? Que sont l’Infowar, le Netwar et le Mediawar ? Quelles réflexions peut-on faire à propos de la culture du crime et de ses relations avec la technologie ? Qu’est-ce que c’est que l’Open Source INTelligence ?Aujourd’hui, le criminologue doit connaître l’importance de la culture numérique, de même qu’il a besoin d’un savoir-faire lié aux technologies de l’information et de la communication dans le but de prévenir et de contrôler la criminalité.

    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. 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

    Using everyday technology (ET) is a prerequisite for activities and participation at home and in the community. It is well known that persons with an acquired brain injury (ABI) can have limitations in activities of daily living but our knowledge of their difficulties using ET is not known. Thirty-six persons (27 men and 9 women, mean age 44 years, age range 26-60) with an ABI (2-10 years post injury) were interviewed, using the Everyday Technology Use Questionnaire (ETUQ), about their perceived difficulties using ET and how these difficulties influenced their everyday activities and their possibilities to participate at home and in the community. A majority (78%) of the persons reported difficulties using ET. The most common difficulties were related to the use of telecommunication and computers. Despite these difficulties, a majority still used most objects and services independently. Twenty-six participants (72%) perceived that their difficulties using ET influenced their everyday activities and their possibility to participate at home and in the community. The results indicate that rehabilitation following an ABI should consider whether clients' use of ET influences their activity and participation and adopt interventions accordingly. The results also indicate that difficulties using ET need to be considered in the design of community services to prevent societal barriers.

    This is the seventh edition of the Vehicle Technologies Market Report, which details the major trends in U.S. light-duty vehicle and medium/heavy truck markets as well as the underlying trends that caused them. This report is supported by the U.S. Department of Energy s (DOE) Vehicle Technologies Office (VTO), and, in accord with its mission, pays special attention to the progress of high-efficiency and alternative-fuel technologies. After opening with a discussion of energy and economics, this report features a section each on the light-duty vehicle and heavy/medium truck markets, and concluding with a section each on technology and policy. The first section on Energy and Economics discusses the role of transportation energy and vehicle markets on a national (and even international) scale. For example, Figures 12 through 14 discuss the connections between global oil prices and U.S. GDP, and Figures 22 and 23 show U.S. employment in the automotive sector. The following section examines Light-Duty Vehicle use, markets, manufacture, and supply chains. Figures 27 through 63 offer snapshots of major light-duty vehicle brands in the United States and Figures 70 through 81 examine the performance and efficiency characteristics of vehicles sold. The discussion of Medium and Heavy Trucks offers information on truck sales (Figures 90 through 94) and fuel use (Figures 97 through 100). The Technology section offers information on alternative fuel vehicles and infrastructure (Figures 105 through 118), and the Policy section concludes with information on recent, current, and near-future Federal policies like the Corporate Average Fuel Economy standard (Figures 130 through 137). In total, the information contained in this report is intended to communicate a fairly complete understanding of U.S. highway transportation energy through a series of easily digestible nuggets. Suggestions for future expansion, additional information, or other improvements are most welcome.

    This report presents studies on the irradiation effects in low-alloy reactor pressure vessel steels. The Fourth Heavy-Section Steel Technology (HSST) Irradiation Series, almost completed, was aimed at elastic-plastic and fully plastic fracture toughness of low-copper weldments (''current practice welds''). A typical nuclear pressure vessel plate steel was included for statistical purposes. The Fifth HSST Irradiation Series, now in progress, is aimed at determining the shape of the K/sub IR/ curve after significant radiation-induced shift of the transition temperatures. This series includes irradiated test specimens of thicknesses up to 100 mm and weldment compositions typical of early nuclear power reactor pressure vessel welds. 27 refs., 22 figs

    Full Text Available Early childhood is a critical period for development of cognitive function, but research on the association between physical activity and cognitive function in preschool children is limited and inconclusive. This study aimed to examine the association between technology-assessed physical activity and cognitive function in preschool children. A cross-sectional analysis of baseline data from the Physical Activity and Cognitive Development Study was conducted in Shanghai, China. Physical activity was measured with accelerometers for 7 consecutive days, and cognitive functions were assessed using the Chinese version of Wechsler Young Children Scale of Intelligence (C-WYCSI. Linear regression analyses were used to assess the association between physical activity and cognitive function. A total of 260 preschool children (boys, 144; girls, 116; mean age: 57.2 ± 5.4 months were included in analyses for this study. After adjusting for confounding factors, we found that Verbal Intelligence Quotient, Performance Intelligence Quotient, and Full Intelligence Quotient were significantly correlated with light physical activity, not moderate to vigorous physical activity, in boys. Standardized coefficients were 0.211, 0.218, and 0.242 (all p < 0.05 in three different models, respectively. However, the correlation between physical activity and cognitive functions were not significant in girls (p > 0.05. These findings suggest that cognitive function is apparently associated with light physical activity in boys. Further studies are required to clarify the sex-specific effect on physical activity and cognitive functions.

  15. Multiple ETS family proteins regulate PF4 gene expression by binding to the same ETS binding site.

    Directory of Open Access Journals (Sweden)

    Yoshiaki Okada

    Full Text Available In previous studies on the mechanism underlying megakaryocyte-specific gene expression, several ETS motifs were found in each megakaryocyte-specific gene promoter. Although these studies suggested that several ETS family proteins regulate megakaryocyte-specific gene expression, only a few ETS family proteins have been identified. Platelet factor 4 (PF4 is a megakaryocyte-specific gene and its promoter includes multiple ETS motifs. We had previously shown that ETS-1 binds to an ETS motif in the PF4 promoter. However, the functions of the other ETS motifs are still unclear. The goal of this study was to investigate a novel functional ETS motif in the PF4 promoter and identify proteins binding to the motif. In electrophoretic mobility shift assays and a chromatin immunoprecipitation assay, FLI-1, ELF-1, and GABP bound to the -51 ETS site. Expression of FLI-1, ELF-1, and GABP activated the PF4 promoter in HepG2 cells. Mutation of a -51 ETS site attenuated FLI-1-, ELF-1-, and GABP-mediated transactivation of the promoter. siRNA analysis demonstrated that FLI-1, ELF-1, and GABP regulate PF4 gene expression in HEL cells. Among these three proteins, only FLI-1 synergistically activated the promoter with GATA-1. In addition, only FLI-1 expression was increased during megakaryocytic differentiation. Finally, the importance of the -51 ETS site for the activation of the PF4 promoter during physiological megakaryocytic differentiation was confirmed by a novel reporter gene assay using in vitro ES cell differentiation system. Together, these data suggest that FLI-1, ELF-1, and GABP regulate PF4 gene expression through the -51 ETS site in megakaryocytes and implicate the differentiation stage-specific regulation of PF4 gene expression by multiple ETS factors.

    Familial Mediterranean fever (FMF) is a genetic disease, characterized by attacks of fever, arthritis, serositis and pain. Behçet's disease (BD) is an inflammatory disorder with a genetic basis, characterized by oral and genital ulcers, uveitis, pustular erythematous cutaneous lesions, arthritis, central nervous system involvement and possible vascular manifestations such as venous thrombosis, arteritis and aneurysms. To investigate the association and actual differentiation between these two entities in a large-scale population-based study. Data for this study was collected from the databases of "Clalit Health Services", the largest state-mandated health service organization in Israel. All adult members diagnosed with BD were included (n=892) and as well as their age- and sex-matched controls (n=4444), creating a cross-sectional population-based study. Medical records of all subjects were analyzed for documented FMF. A logistic regression model was done to estimate how BD, age, gender, BMI, ethnicity and socioeconomic status contributed as risk factors for FMF. The proportion of FMF in patients with BD increased compared with those reported in controls (5.83% and 0.23%, respectively, P30. Our data imply that understating the differentiation between FMF and BD is not evident and clear in a real-life population of patients with BD.

    'industrie chimique, d'autre part il s'interroge sur les technologies possibles de destruction de N2O dans les cas où sa teneur dans les fumées ou autres effluves industriels pose des problèmes. Comme les émissions, aussi bien que les moyens de les abattre, sont fortement tributaires des mécanismes chimiques responsables de la production et de la destruction du N2O, une introduction substantielle sur la cinétique homogène et hétérogène de sa formation/réduction, telle qu'elle apparaît dans un contexte de combustion, est fournie, permettant au lecteur de comprendre le pourquoi de ces émissions et le comment des technologies d'abattement suggérées.

  8. Evapotranspiration (ET) covers.

    Science.gov (United States)

    Rock, Steve; Myers, Bill; Fiedler, Linda

    2012-01-01

    Evapotranspiration (ET) cover systems are increasingly being used at municipal solid waste (MSW) landfills, hazardous waste landfills, at industrial monofills, and at mine sites. Conventional cover systems use materials with low hydraulic permeability (barrier layers) to minimize the downward migration of water from the surface to the waste (percolation), ET cover systems use water balance components to minimize percolation. These cover systems rely on soil to capture and store precipitation until it is either transpired through vegetation or evaporated from the soil surface. Compared to conventional membrane or compacted clay cover systems, ET cover systems are expected to cost less to construct. They are often aesthetic because they employ naturalized vegetation, require less maintenance once the vegetative system is established, including eliminating mowing, and may require fewer repairs than a barrier system. All cover systems should consider the goals of the cover in terms of protectiveness, including the pathways of risk from contained material, the lifecycle of the containment system. The containment system needs to be protective of direct contact of people and animals with the waste, prevent surface and groundwater water pollution, and minimize release of airborne contaminants. While most containment strategies have been based on the dry tomb strategy of keeping waste dry, there are some sites where adding or allowing moisture to help decompose organic waste is the current plan. ET covers may work well in places where complete exclusion of precipitation is not needed. The U.S. EPA Alternative Cover Assessment Program (ACAP), USDOE, the Nuclear Regulatory Commission, and others have researched ET cover design and efficacy, including the history of their use, general considerations in their design, performance, monitoring, cost, current status, limitations on their use, and project specific examples.

    as ‘the missing link’ in past climate negotiations. We argue that farmers have relatively low marginal reduction costs and that consequences in terms of the effect on permit price and technology are overall positive in the EU Emission Trading System (ETS). Thus, we propose a project-based system......Farmers in the EU do not trade greenhouse gases under the Kyoto agreement. This is an empirical puzzle because agriculture is a significant contributor of greenhouse gases (GHG) in the EU and may harvest private net gains from trade. Furthermore, the US has strongly advocated land-use practices...... for including the farming practices in the EU ETS that reduces the uncertainty from measuring emission reduction in this sector. The system encourages GHG reduction either by introducing a new and less polluting practice or by reducing the polluting activity. When doing so, farmers will receive GHG permits...

    Full text: The European Atomic Energy Community (Euratom) Research and Training framework programmes are benefiting from a consistent success in pursuing excellence in research and facilitating Pan-European collaborative efforts across a broad range of nuclear science and technologies, nuclear fission and radiation protection. To fulfil Euratom R&D programmes keys objectives of maintaining high levels of nuclear knowledge and building a more dynamic and competitive European industry, promotion of Pan-European mobility of researchers are implemented by co-financing transnational access to research infrastructures and joint research activities through to research and innovation and coordination and support actions funding schemes. Establishment by the research community of European technology platforms are being capitalized. Mapping of research infrastructures and E&T capabilities is allowing a closer cooperation within the European Union and beyond, benefiting from multilateral international agreements and from closer cooperation between Euratom, OECD/NEA and IAEA and international fora. “Euratom success stories” in facilitating Pan-European E&T collaborative efforts through research and training framework programmes show the benefits of research efforts in key fields, of building an effective “critical mass”, of promoting the creation of “centres of excellence” with an increased support for “open access to key research infrastructures”, exploitation of research results, management of knowledge, dissemination and sharing of learning outcomes.

    Weiss, Christina; Griesmayer, Erich; Guerrero, Carlos

    A novel detector based on the chemical vapor deposition (CVD) diamond technology has been developed in the framework of this PhD, for the experimental determination of (n,a) cross-sections at the neutron time-of-flight facility n_TOF at CERN. The 59Ni(n,a)56Fe cross-section, which is relevant for astrophysical questions as well as for risk-assessment studies in nuclear technology, has been measured in order to validate the applicability of the detector for such experiments. The thesis is divided in four parts. In the introductory part the motivation for measuring (n,a) cross-sections, the experimental challenges for such measurements and the reasons for choosing the CVD diamond technology for the detector are given. This is followed by the presentation of the n_TOF facility, an introduction to neutron-induced nuclear reactions and a brief summary of the interaction of particles with matter. The CVD diamond technology and the relevant matters related to electronics are given as well in this first part of the t...

    The infructescence of Platycarya strobilacea Sieb. et Zucc is a well-known traditional medicine in China, Japan and Korea. The infructescence of P. strobilacea Sieb. et Zucc is a rich source of ellagitannins that are composed of ellagic acid (EA) and gallic acid, linked to a sugar moiety. The aim of this study was to prepare EA by acid hydrolysis of crude tannins from the infructescence of P. strobilacea Sieb. et Zucc, and establish a new technological processing method for EA. The natural antioxidant EA was prepared by using the water extraction of infructescence of P. strobilacea Sieb. et Zucc, evaporation, condensation, acid hydrolysis and prepared by the process of crystallisation. The yield percentage of EA from crude EA was more than 20% and the purity of the product was more than 98%, as identified by using HPLC. The structure was identified on the basis of spectroscopic analysis and comparison with authentic compound.

  18. Fission cross-section normalization problems

    International Nuclear Information System (INIS)

    Wagemans, C.; Ghent Rijksuniversiteit; Deruytter, A.J.

    1983-01-01

    The present measurements yield σsub(f)-data in the neutron energy from 20 MeV to 30 keV directly normalized in the thermal region. In the keV-region these data are consistent with the absolute σsub(f)-measurements of Szabo and Marquette. For the secondary normalization integral I 2 values have been obtained in agreement with those of Gwin et al. and Czirr et al. which were also directly normalized in the thermal region. For the I 1 integral, however, puzzling low values have been obtained. This was also the case for σsub(f)-bar in neutron energy intervals containing strong resonances. Three additional measurements are planned to further investigate these observations: (i) maintaining the actual approx.2π-geometry but using a 10 B-foil for the neutron flux detection (ii) using a low detection geometry with a 10 B- as well as a 6 Li-flux monitor. Only after these measurements definite conclusions on the I 1 and I 2 integrals can be formulated and final σsub(f)-bar-values can be released. The present study also gives some evidence for a correlation between the integral I 2 and the neutron flux monitor used. The influence of a normalization via I 1 or I 2 on the final cross-section has been shown. The magnitude of possible normalization errors is illustrated. Finally, since 235 U is expected to be an ''easy'' nucleus (low α-activity high σsub(f)-values), there are some indications that the important discrepancies still present in 235 U(n,f) cross-section measurements might partially be due to errors in the neutron flux determination

    Only 2 years left for 20th century. This 100 years, population increased 3 times, actual GNP became 42 times higher, energy consumption was increased to 52 times and amount of CO{sub 2} generation has been 31 times higher. Even at present after 20 years of second oil chock, consumption of energy and amount of CO{sub 2} generation are in a increasing trend. Among them, in public welfare section, energy consumption is increasing along with the transportation section. In residence, increase in energy demand is due to the improvement of residential environment, wide application of home electrical appliances, and increase in official energy demand is due to wider floor space, wide use of OA equipments, automatic vender machines. On the other hand, energy saving of air conditioning, refrigerator, television and so forth has been progressed widely. However, progress of these save energy technologies also is not sufficient to cope with the speed of energy consumption. Results differ with the progress of technology development, speed of its wide use and so forth, however, reduction of generation of CO{sub 2} to a 1990 level in public welfare section is very difficult. General measures like perfect technology development, economical aid, advertisement and so forth are in demand

Scott démontre que les deux auteurs jouent différemment du métissage et de son rapport avec le colonialisme : tandis que Hamelin met en scène des personnages autochtones dévirilisés et en perte d’authenticité, Highway s’appuie sur la notion amérindienne de bispiritualité pour créer des personnages queer qui transcendent les constructions binaires sur lesquelles se base la masculinité hégémonique. Corrie Scott examines the notion of métissage in the representation of Indigenous masculinities in Cowboy by Québécois novelist Louis Hamelin (1992 and in Kiss of the Fur Queen by Cree novelist Tomson Highway (1998. Scott shows the different ways in which the two authors approach the notion of métissage and its relationship with colonialism: while Hamelin depicts hybrid Indigenous characters as less authentic and virile, Highway embraces a queer poetics that questions hegemonic masculinities and gendered colonial stereotypes through hybrid fictional male identities. An intersectional theoretical framework proves essential to the analysis of hegemonic masculinities which function hand in hand with colonialism.

    Full Text Available En remplaçant la part des cotisations sociales à la charge de l’employeur par un éco-impôt sur le capital polluant, l’Etat peut inciter les entreprises à investir dans les trajectoires technologiques de la durabilité. Cet article expose un modèle macroéconomique à trois facteurs qui montre comment la fixation conjointe et combinée du taux de cotisations sociales et du taux d'éco-impôt peut assurer la stabilité globale des prix, garantir la neutralité budgétaire et conserver en l’état la compétitivité prix. Contrôlée par le ministère du développement durable, la déformation de la fonction de production provoquée par une fiscalité directe favorable au capital non polluant et au travail augmente le volume de l’emploi et améliore la qualité environnementale sans détériorer la compétitivité ni déséquilibrer les comptes sociaux.Replacing the welfare cost by an eco-taxation based on polluting capital can incite companies to invest in the technological trajectories for sustainability. This paper proposes a macroeconomic three factors model in which the jointed and combined determination of welfare cost and eco-taxation rates can maintain the global price stability, guarantees the budget balance of fiscal transfers and keeps the state of the competitiveness price as it was before. Controlled by the ministry of sustainable development, the deformation of the function of production, caused by a direct tax system favorable to the non-polluting capital and to the labour, increases the employment and improves the environmental quality without negative effects on competitiveness and social accounts.

    Rendre les collections accessibles en ligne est devenu pour les institutions culturelles, d'enseignement et de recherche, un des défis majeurs du début du XXIe siècle. Les projets sont dès à présent nombreux, et concernent tous les types d'établissements et tous les supports. Mener à bien une opération de numérisation et de mise en ligne requiert un ensemble de repères et de connaissances pour l'organisation et la mise en oeuvre d'un projet de numérisation durable. Donner les clés du domaine en se fondant sur des savoirs pratiques et concrets est l'ambition de cet ouvrage, qui fournit un mode opératoire précis pour chacune des grandes étapes à prendre en compte - de la capture à la conservation numérique, en passant par l'interopérabilité, le référencement, et en intégrant l'environnement juridique et réglementaire. Coordonné par Thierry Claerr et Isabelle Westeel, spécialistes du sujet et responsables de formations sur la numérisation et la création de bibliothèques numériques,...

    Bonke, Sten

    The aim of this text is to discuss and to develop the concept of technology management in relation to the empirical field of construction projects. In the first of the two main sections central theories and their derived assertions concerning technology management criteria are summed up...... Fixed Link construction project. Finally on this basis the concluding remarks are pointing to the main theoretical problems and their practical implementations for the introduction of a technology management discipline in construction....... in a schematic theoretical framework. Hereafter the general characteristics of construction are examined from the point of view of serving as an empirical field for technology management analysis. In the second section the technology management theme is associated with the empirical properties of the Great Belt...

  13. Relativité et gravitation

    1992-01-01

    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...

  14. Ecuadorian Cancer Patients’ Preference for Information and Communication Technologies: Cross-Sectional Study

    Science.gov (United States)

    2018-01-01

    Background The instantaneous spread of information, low costs, and broad availability of information and communication technologies (ICTs) make them an attractive platform for managing care, patient communication, and medical interventions in cancer treatment. There is little information available in Latin America about the level of usage of ICTs for and by cancer patients. Our study attempts to fill this gap. Objective The aim of this study was to assess the level of ICT use and patterns of preferences among cancer patients. Methods We conducted an anonymous cross-sectional survey study in 500 Ecuadorian cancer patients. This questionnaire consisted of 22 items about demographic and clinical data, together with the preferences of people who use ICTs. Chi-square, crude, and adjusted logistic regressions were performed. Results Of the total, 43.2% (216/500) of participants reported that they had access to the Internet, and 25.4% (127/500) reported that they neither owned a cell phone nor did they have access to the Internet. The Internet constituted the highest usage rate as a source of information about malignant diseases (74.3%, 162/218) regardless of age (PWhatsApp (66.5%, 145/218) and short message service (SMS) text messaging (61.0%, 133/218) were widely reported as interesting communication channels. Similarly, WhatsApp (72.0%, 157/218) followed by SMS (63.8%, 139/218) were reported as the preferred ICTs through which patients would like to ask physicians about diseases. Adjusted regression analysis showed that patients aged between 40 and 64 years were more likely to be interested in receiving information through SMS (odds ratio, OR 5.09, 95% CI 1.92-13.32), as well as for asking questions to physicians through this same media (OR 9.78, CI 3.45-27.67) than the oldest group. Conclusions WhatsApp, SMS, and email are effective and widely used ICTs that can promote communication between cancer patients and physicians. According to age range, new ICTs such as

    Full Text Available Notre article s’efforce de présenter les effets de ce que nous nommerons les « technométhodes », c’est-à-dire « le cadre structurant imposé aux praticiens d’une organisation par les technologies et ce principalement depuis le développement et la généralisation de la micro-informatique, technologies qui permettent aujourd’hui à chaque poste de travail de traiter de l’information grâce aux applications logicielles multiples : logiciels bureautiques, liés aux TICs, logiciels de gestion spécifiques. Les « technométhodes » forment au sein de chaque organisation un ensemble et une configuration (Elias, 1981 qui lui est propre et qui est liée à sa culture, son histoire et sa stratégie. Elles sont le fruit de pratiques collectives, d’adhésion, de résistance, voire de contournement du cadre imposé. Ces « technométhodes », résultats de processus historiques, ne sont pas neutres car le produit d’une interaction entre d’une part des choix managériaux et les logiques d’acteurs d’une organisation ». Nous nous appuierons sur une étude menée sur l’organisation d’un service d’une dizaine de salariés, appartenant à une institution d’aide et de conseil en matière de gestion de personnel territorial de l’ouest de la France. Cette étude sera l’occasion de faire émerger deux modèles culturels d’agents confrontés au changement organisationnel induit par ces « technométhodes » : les « alpinistes », agents les plus anciens, porteurs de savoirs d’expérience accumulés au fil des années, attachés à développer des relations affectives avec les clientèles et ancrés dans une culture « papier », développant par ce fait des « ethno-technométhodes » et des « parachutistes »1, agents dans l’ensemble plus jeunes ou aux parcours plus diversifiés, plus immergés dans la culture numérique, et cherchant à développer une approche plus technique des pratiques du

    Full Text Available Several models are available for the analysis of pooled time-series cross-section (TSCS data, defined as “repeated observations on fixed units” (Beck and Katz 1995. In this paper, we run the following models: (1 a completely pooled model, (2 fixed effects models, and (3 multi-level/hierarchical linear models. To illustrate these models, we use a Generalized Least Squares (GLS estimator with cross-section weights and panel-corrected standard errors (with EViews 8 on the cross-national homicide trends data of forty countries from 1950 to 2005, which we source from published research (Messner et al. 2011. We describe and discuss the similarities and differences between the models, and what information each can contribute to help answer substantive research questions. We conclude with a discussion of how the models we present may help to mitigate validity threats inherent in pooled time-series cross-section data analysis.

    Ramamurthy, V.S.; Kapoor, S.S.

    1993-01-01

    Apparent discrepancies between values of extra-push energies for fusion of two heavy nuclei derived through measurements of fusion evaporation residue cross sections and of differential fission cross sections have been reported by Keller et al. We show here that with the inclusion of the recently proposed preequilibrium fission decay channel in the analysis, there is no inconsistency between the two sets of data in terms of the deduced extra-push energies
