  9. 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.

  6. Heavy-section steel technology program: Fracture issues

    International Nuclear Information System (INIS)

    Pennell, W.E.

    1992-01-01

    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

    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.

    The worldwide growth in industrial gas turbine installations during the past 10 years has spawned a parallel growth of the gas turbine hot section repair business. Repair procedures do not follow those of the aircraft industry, but vary by company, with few revealing what they do and how they do it. Repair technology follows a three-phase service approach designed to reinforce dedication to excellence before commercialization. General Electric has been a leader in the field, with the operation of hot gas path speciality shops, the development of multi-vane nozzles, and special bucket alloys. 6 figures.

  12. Heavy Section Steel Technology Program. Part II. Intermediate vessel testing

    International Nuclear Information System (INIS)

    Whitman, G.D.

    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

    La technologie médicale connaît une croissance exponentielle dans le milieu de la santé, mais elle n'a toutefois pas suivi le rythme observé dans des industries similaires, telles que l'aéronautique. Les nouvelles technologies ont le potentiel d'accroître la sécurité des patients, mais si leur introduction dans le milieu de la santé n'est pas coordonnée de manière réfléchie et proactive, la chaîne de la sécurité risque de s'en trouver affaiblie, ce qui exposera les patients à des risques. Trois concepts qui représentent la chaîne de la sécurité sont décrits. Les équipes de direction et le personnel de première ligne devraient tous les connaître, les étudier et s'y investir afin de maintenir la chaîne de la sécurité intacte et d'éviter qu'un seul maillon soit affaibli par l'adoption d'une nouvelle technologie.

  9. Nuclear facilities: repair and replacement technologies; Installations nucleaires: technologies de reparation et de remplacement

    Energy Technology Data Exchange (ETDEWEB)

    2005-07-01

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

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

  5. Best available technology equivalent controls for B Plant Process Condensate: Tank farm process technology section

    International Nuclear Information System (INIS)

    1988-11-01

    This report evaluates whether proposed controls for the B Plant Process Condensate effluent stream are equivalent to Best Available Technology (BAT) economically achievable. Methods to determine whether the proposed controls for the BCP were equivalent to BAT originated from the Guidance Document for the Hanford Site. The BAT performance standards, which originate from the Clean Water Act, are to be applied to all contaminated liquid effluent discharges currently going to the soil column at the Hanford Site. The B Plant BAT evaluation addressed pollutants that had not been regulated traditionally under Federal or State water-pollution control programs. As a result, only comparisons could be made to existing radiation and water quality standards, and a BAT determination based on the effluent guidelines method (as outlined in the BAT Guidance Document) was not possible. Due to the variability and inconsistency of factors with comparable streams, such as the effluent stream at the Savannah River Plant, a BAT determination by the technology transfer method and treatability studies method was not possible. By using the generic treatment systems method, a one-or two-stage treatment system for dissolved solids removal was concluded to be equivalent to BAT. By performing two economic achievability tests, a one-stage treatment system consisting of mixed bed ion exchange columns was considered to be cost effective and equivalent to BAT. 13 refs., 4 figs., 5 tabs

  6. Heavy-Section Steel Technology Program: Recent developments in crack initiation and arrest research

    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

    Quantification of immunohistochemically (IHC) labelled tissue sections typically yields semi-quantitative results. Visualising infrared (IR) 'tags', with an appropriate scanner, provides an alternative system where the linear nature of the IR fluorophore emittance enables realistic quantitative fluorescence IHC (QFIHC). Importantly, this new technology enables entire tissue sections to be scanned, allowing accurate area and protein abundance measurements to be calculated from rapidly acquired images. Here, some of the potential benefits of using IR-based tissue imaging are examined, and the following are demonstrated. Firstly, image capture and analysis using IR-based scanning technology yields comparable area-based quantification to those obtained from a modern high-resolution digital slide scanner. Secondly, IR-based dual target visualisation and expression-based quantification is rapid and simple. Thirdly, IR-based relative protein abundance QIHC measurements are an accurate reflection of tissue sample protein abundance, as demonstrated by comparison with quantitative fluorescent Western blotting data. In summary, it is proposed that IR-based QFIHC provides an alternative method of rapid whole-tissue section low-resolution imaging for the production of reliable and accurate quantitative data. © 2015 The Authors.

  19. 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 work performed to revise the REAC data file of Mann et al., containing cross-sections for neutron activation and transmutation reactions for use in fusion-reactor technology, is described. The revisions were made by means of renormalizations of the cross-sections to experimental data at 14.5 MeV or to data from 14.5 MeV systematics. Uncertainty estimates are given for the systematics. Furthermore, a number of reactions have been added. The file essentially contains cross-sections for almost all stable and unstable nuclides with half lives exceeding 1 day. If a reaction can produce one or two isomers the cross-sections for producing the ground and isomeric states are given separately. In most cases these cross-sections were obtained by a simple scaling using isomer ratios at 14.5 MeV, based upon experimental data or recently developed systematics. For about 50 reactions leading to long-lived states a special treatment was followed including a detailed uncertainty analysis. The revised file is called REAC-ECN-3. A version with multi-group cross-sections has also been generated (GREAC-ECN-3). The report contains an Appendix with 14.5 MeV cross-sections for all isotopes considered in the data file. 7 figs.; 29 refs.; 5 tabs.; 1 appendix

    To determine whether health information technology (IT) systems are associated with better patient safety in acute care settings. In a cross-sectional retrospective study, data on hospital patient safety performance for October 2008 to June 2010 were combined with 2007 information technology systems data. The sample included 3002 US non-federal acute care hospitals. Electronic health record (EHR) system was coded as a composite dichotomous variable based on the presence of 10 major clinical and administrative applications that (if in use) could potentially meet stage 1 "meaningful use" objectives. The surgical IT system was measured as a dichotomous variable if a hospital used at least 1 of the perioperative, preoperative, or postoperative information systems. Hospital patient safety performance was measured by risk-standardized estimated rates per 1000 admissions. Statistical analyses were conducted using an estimated dependent variable methodology with gamma-log link-based weighted generalized linear models, adjusting for hospital characteristics, historical composite process quality, and propensity for EHR adoption. We found that the use of surgical IT systems was associated with 7% to 26% lower rates for 7 of 8 patient safety indicators (incidence rate ratio [IRR] range from 0.74 to 0.93; all P values hospitals. However, the cross-sectional design limits our ability to make causal conclusions.

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

    1998-07-01

    The rationale for the development of over-the-horizon (OTH) radar systems operating at frequencies in the HF band arose out of a perceived need for an early-warning defense network. That need changed with the end of the Cold War; however, today OTH radars play a major role in the CounterDrug Program for the interdiction of drug-smuggling aircraft. This special section of Radio Science is devoted to a review of OTH radar technology, with emphasis on contemporary developments in this field. The collection of papers presented here has evolved largely from research and development efforts directed to improving the performance of OTH radar systems deployed both in the United States and in Australia.

    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.

    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.

  18. 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

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

There is little information in Latin America about usage frequency of ICTs in asthmatic patients. The analysis undertaken consisted of an observational, cross-sectional study that aimed to identify the frequency and type of ICTs most often used by asthmatics. The Spanish version of the Michigan questionnaire was employed in five Latin American countries. Age and educational level was categorised. Logistic regression was performed among these groups concerning the frequency of ICT usage and the level of interest shown in seeking and receiving information about asthma. In total, 673 asthma patients were surveyed. The mean age was 43.44 years. Over two-thirds of the participants were female (68.4%. The most used ICT was the short message service (SMS (69.9%. SMS and E-mail are useful tools for communicating (i.e. receiving and seeking information with all asthma patients, irrespective of their age. WhatsApp (61.5% and Facebook (32.0% were rated as being the most interesting channels of communication for receiving information.

    The technical and cost challenges of hydrogen technology were discussed. Stuart Energy manufactures appliances that generate hydrogen from water, using electricity. The basis for the water electrolysis process is hydrogen generation and supply. This is the basis for fuel cell technology for all applications, energy storage, grid stabilization, and electric power generation from renewable energy sources. Stuart Energy develops the technology for the hydrogen economy for industrial, transportation, and regenerative power markets. In the past decade, the company has reduced the cost and size of its equipment significantly, creating a viable solution to the infrastructure needs of a hydrogen based economy. This presentation focused in part on the new techniques that are necessary to attract and maintain investor interest in Stuart Energy with particular emphasis on investor emotions since Stuart Energy's initial public offering (IPO) in October 2000. At the time, oil prices were high and hydrogen technology was in demand. Since that time, the hydrogen index has dropped significantly and share values are far from their peak. The author explained how stock valuation is determined and emphasized that the hydrogen economy will be built on steady technology development and not on volatile shareholder emotions. The technology promises to generate and use hydrogen in a manner that offers the same or better performance than today's technology, at greater convenience and lower cost. Hydrogen also offers benefits of energy security, higher efficiency and sustainable development. 1 ref

    Mental and emotional self-help apps have emerged as potential mental illness prevention and treatment tools. The health behavior theory mechanisms by which these apps influence mental health-related behavior change have not been thoroughly examined. The objective of this study was to examine the association between theoretical behavior change mechanisms and use of mental and emotional self-help apps and whether the use of such apps is associated with mental health behaviors. This study utilized a cross-sectional survey of 150 users of mental or emotional health apps in the past 6 months. Survey questions included theory-based items, app engagement and likeability items, and behavior change items. Stata version 14 was used to calculate all statistics. Descriptive statistics were calculated for each of the demographic, theory, engagement, and behavior variables. Multiple regression analysis was used to identify factors associated with reported changes in theory and separately for reported changes in actual behavior after controlling for potentially confounding variables. Participants reported that app use increased their motivation, desire to set goals, confidence, control, and intentions to be mentally and emotionally healthy. Engagement (Ptheory items, whereas perceived behavior change was positively associated with theory (Ptheory items. Future efforts should consider the value of impacting key theoretical constructs when designing mental and emotional health apps. As apps are evaluated and additional theory-based apps are created, cost-effective self-help apps may become common preventative and treatment tools in the mental health field. ©Benjamin T Crookston, Joshua H West, P Cougar Hall, Kaitana Martinez Dahle, Thomas L Heaton, Robin N Beck, Chandni Muralidharan.

    2014-11-01

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

    Magnetic resonance imaging (MRI) allows for the delineation between normal and abnormal tissue on a macroscopic scale, sampling an entire tissue volume three-dimensionally. While MRI is an extremely sensitive tool for detecting tissue abnormalities, association of signal changes with an underlying pathological process is usually not straightforward. In the central nervous system, for example, inflammation, demyelination, axonal damage, gliosis, and neuronal death may all induce similar findings on MRI. As such, interpretation of MRI scans depends on the context, and radiological-histopathological correlation is therefore of the utmost importance. Unfortunately, traditional pathological sectioning of brain tissue is often imprecise and inconsistent, thus complicating the comparison between histology sections and MRI. This article presents novel methodology for accurately sectioning primate brain tissues and thus allowing precise matching between histology and MRI. The detailed protocol described in this article will assist investigators in applying this method, which relies on the creation of 3D printed brain slicers. Slightly modified, it can be easily implemented for brains of other species, including humans. PMID:28060281

  17. Heavy-Section Steel Technology Program intermediate-scale pressure vessel tests

    International Nuclear Information System (INIS)

    Bryan, R.H.; Merkle, J.G.; Smith, G.C.; Whitman, G.D.

    1977-01-01

    The tests of intermediate-size vessels with sharp flaws permitted the comparison of experimentally observed behavior with analytical predictions of the behavior of flawed pressure vessels. Fracture strains estimated by linear elastic fracture mechanics (LEFM) were accurate in the cases in which the flaws resided in regions of high transverse restraint and the fracture toughness was sufficiently low for unstable fracture to occur prior to yielding through the vessel wall. When both of these conditions were not present, unstable fracture did occur, always preceded by stable crack growth; and the cylinders with flaws initially less than halfway through the wall attained gross yield prior to burst. Predictions of failure pressure of the vessels with flawed nozzles, based upon LEFM estimates of failure strain, were very conservative. LEFM calculations of critical load were based upon small-specimen fracture toughness test data. Whenever gross yielding preceded failure, the actual strains achieved were considerably greater than the estimated strains at failure based on LEFM. In such cases the strength of the vessel may be no longer dependent upon plane-strain fracture toughness but upon the capacity of the cracked section to carry the imposed load stably in the plastic range. Stable crack growth, which has not been predictable quantitatively, is an important factor in elastic-plastic analysis of strength. The ability of the flawed vessels to attain gross yield in unflawed sections has important qualitative implications on pressure vessel safety margins. The gross yield condition occurs in light-water-reactor pressure vessels at about 2 x design pressure. The intermediate vessel tests that demonstrated a capacity for exceeding this load confirm that the presumed margin of safety is not diminished by the presence of flaws of substantial size, provided that material properties are adequate

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

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

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

    The National Cancer Institute's Center to Reduce Cancer Health Disparities has created pilot training opportunities under the "Continuing Umbrella of Research Experiences" program that focus on emerging technologies. In this pilot project, an 18-month cancer biology research internship was reinforced with: instruction in an emerging technology (proteomics), a transition from the undergraduate laboratory to a research setting, education in cancer health disparities, and community outreach activities. A major goal was to provide underrepresented undergraduates with hands-on research experiences that are rarely encountered at the undergraduate level, including mentoring, research presentations, and participation in local and national meetings. These opportunities provided education and career development for the undergraduates, and they have given each student the opportunity to transition from learning to sharing their knowledge and from being mentored to mentoring others. Here, we present the concepts, curriculum, infrastructure, and challenges for this training program along with evaluations by both the students and their mentors.

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

    In France, investment expenses in information and communication technologies (ICT) reached 162 billions of French francs in 1999 with an average annual growth of 13.3% during the 1989-1999 era. In parallel, the end-use energy consumption reached 212 Mtep in 1999 with an average annual growth of 1.55% during the same period. The introduction and spreading of computer equipments and softwares in offices is one possible explanation to this evolution. This study uses the data available for the tertiary sector to model and quantify the impact of ICTs development on the electricity consumption in this sector and draws out some consumption forecasts according to different hypotheses.

    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

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.

The Cenozoic Alpine fold-and-thrust setting, which characterizes this region, presents flat-over-flat shear planes acting along originally stratigraphic contacts, where stratigraphic continuity is obviously maintained. The ramp sectors present steeply dipping bedding attitudes, and there is no need to invoke and to force prograding clinoforms with unrealistic angles to justify them. The balanced geological cross section proposed by Arragoni et al. (2016) is fully supported by robust newly collected structural data and is compatible with the overall tectonic setting, while the interpretation proposed by Berra et al. (2017) lacks a detailed structural investigation. We believe that the partial application of the techniques available to modern geology may lead to incorrect interpretations, thus representing an obstacle for the progress of knowledge in the Earth sciences.

    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 (235,238)U and (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 (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 for a wide

    2016-01-01

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

    2010-01-01

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

    Background Substance use disorder research and practice have not yet taken advantage of emerging changes in communication patterns. While internet and social media use is widespread in the general population, little is known about how these mediums are used in substance use disorder treatment. Objective The aims of this paper were to provide data on patients' with substance use disorders mobile phone ownership rates, usage patterns on multiple digital platforms (social media, internet, computer, and mobile apps), and their interest in the use of these platforms to monitor personal recovery. Methods We conducted a cross-sectional survey of patients in 4 intensive outpatient substance use disorder treatment facilities in Philadelphia, PA, USA. Logistic regressions were used to examine associations among variables. Results Survey participants (N=259) were mostly male (72.9%, 188/259), African American (62.9%, 163/259), with annual incomes less than US $10,000 (62.5%, 161/259), and averaged 39 (SD 12.24) years of age. The vast majority of participants (93.8%, 243/259) owned a mobile phone and about 64.1% (166/259) owned a mobile phone with app capabilities, of which 85.1% (207/243) accessed the internet mainly through their mobile phone. There were no significant differences in age, gender, ethnicity, or socio-economic status by computer usage, internet usage, number of times participants changed their phone, type of mobile phone contract, or whether participants had unlimited calling plans. The sample was grouped into 3 age groups (Millennials, Generation Xers, and Baby Boomers). The rates of having a social media account differed across these 3 age groups with significant differences between Baby Boomers and both Generation Xers and Millennials (PMillennials (P<.001). The majority of respondents (70.1%, 181/259) said they would prefer to use a relapse prevention app on their phone or receive SMS (short message service) relapse prevention text messages (72.3%, 186

    This reports 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 January--March 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 eight major areas of research: Hot Cell Operations, Process Chemistry and Thermodynamics, Molten Salt Reactor Experiment (MSRE) Remediation Studies, Chemistry Research, Separations and Materials Synthesis, Fluid Structure 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 Hot Cell Operations included column loading of cesium from Melton Valley Storage Tank supematants using an engineered form of crystalline silicotitanate. A second task was to design and construct a continuously stirred tank reactor system to test the Savannah River-developed process of small-tank tetraphenylborate precipitation to remove cesium, strontium, and transuranics from supematant. Within the area of Process Chemistry and Thermodynamics, the problem of solids formation in process solutions from caustic treatment of Hanford sludge was addressed, including issues such as pipeline plugging and viscosity measurements. Investigation of solution conditions required to dissolve Hanford saltcake was also continued. MSRE Remediation Studies focused on recovery of {sup 233}U and its transformation into a stable oxide and radiolysis experiments to permit remediation of MSRE fuel salt. In the area of Chemistry Research, activities included studies relative to molecular imprinting for

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

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

The primary purpose of this paper is to report on barriers that impede systemic, effective and sustainable technology integration within schools. Even with teacher and administrative support and commitment for THSS, evaluative research indicated minimal change in system capacity as a result of the initiative. Three primary barriers to program sustainability were: 1 schools and school districts did not leverage the opportunity to revisit their existing vision(s, 2 schools and school districts did not use data to make changes, and 3 limited access to technology. Le but de l’initiative « Technology and High School Success (THSS » était d'encourager des stratégies novatrices visant à améliorer le taux d’achèvement des études secondaires dans la province de l’Alberta en utilisant la technologie et un apprentissage centré sur l'élève afin de susciter l'intérêt des élèves. L'objectif principal de cet article est de rendre compte des obstacles entravant l'intégration systémique, efficace et durable de la technologie dans les écoles. La recherche évaluative a révélé des changements minimes dans la capacité systémique à la suite de l'initiative, et ce, malgré l’appui et l’engagement des enseignants et des administrateurs envers le THSS.

    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.

    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.

    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.

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

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

    This thesis has two parts. The first one is devoted to the study of influence of multiple collisions on various variables by means of the interface GEANT-FOPI. The second part deals with the study of mass double differential cross sections relative to rapidity and transverse energy obtained by phase I FOPI detector. It was found that the estimate of the rate of double collisions is strongly dependent on the utilised model and that the influence of multiple collisions on the double differential cross sections was negligible for rapidities near that of mass center. The second part of this work is devoted to the study of double differential cross sections of fragment production. The fitting of experimental distributions with the Boltzmann law seems to be convenient for the Z=1 fragments emitted in central collisions. The hypothesis of a unique pure thermal source is to be excluded for the Z > 1 fragments. In the case of central collisions, the consideration of the collective effects occurring, in the case of a thermal source explosion followed by an isotropic radial collective expansion, has resulted in a unique temperature value for Z=1 and Z=2, as well as, in a value of collective radial speed, of the order of magnitude of 0.3 c, common for all the fragments. The experimental findings achieved with the phase I FOPI detector allowed to conclude firmly that this scenario, implying an isotropic radial expansion, is strongly made evident in case of central reactions. In addition, the comparison of experimental data with the results obtained with the Isospin Quantum Molecular Dynamics model has shown that, in spite of an overall overestimation of distributions, a good agreement between theoretical estimates and experimental data was obtained for the collective temperature and speed values 76 refs.

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

    Various advanced energy conversion systems (ECS) are compared with each other and with current technology systems for their savings in fuel energy, costs, and emissions in individual plants and on a national level. About fifty industrial processes from the largest energy consuming sectors were used as a basis for matching a similar number of energy conversion systems that are considered as candidates which can be made available by the 1985 to 2000 time period. The sectors considered included food, textiles, lumber, paper, chemicals, petroleum, glass, and primary metals. The energy conversion systems included steam and gas turbines, diesels, thermionics, stirling, closed cycle and steam injected gas turbines, and fuel cells. Fuels considered were coal, both coal and petroleum based residual and distillate liquid fuels, and low Btu gas obtained through the on-site gasification of coal. Computer generated reports of the fuel consumption and savings, capital costs, economics and emissions of the cogeneration energy conversion systems (ECS's) heat and power matched to the individual industrial processes are presented for coal fired process boilers. National fuel and emissions savings are also reported for each ECS assuming it alone is implemented.

    2010-09-15

    The progress of science and technology has been so rapid in the last few decades that it receives especial attention in forecasting and foresight exercises. But, because they are too greatly in thrall to the dominant paradigms and hence favour a linear perspective, the experts who deal with these questions pay more attention to the future of technologies than to scientific advances and revolutions. The bulk of their work consists, then, in anticipating, by various different methods (Delphi surveys, Road-maps, etc.), at what date a particular technology might be available (without, however, always correctly gauging the conditions for its social appropriation or the applications to which it might be put). In this article, Pierre Papon expounds a much more original and promising approach for attempting to anticipate the discoveries that are likely radically to transform the fields of scientific knowledge by investigating the phenomena that may potentially lead to fundamental revolutions. After reminding us of the premonitory thinking of a number of authors - in the fields, for example, of genetics and computer science -, he endeavors to describe some of the dominant paradigms, particularly in quantum physics and molecular biology. In this way, he shows the advances they have made possible, and also their limitations, and explores what new scientific leaps forward might occur, bringing radically new technological breakthroughs between now and 2050. Papon reminds us, at the same time that, 'as science is not something isolated within society'; it has a duty to contribute to meeting the great challenges that face us - of work, health, nutrition and sustainable development, particularly where energy and climate are concerned. He therefore examines the ways in which future scientific and technological advances might provide solutions and how important it might be to 'translate the questions society poses into scientific questions'. He thus argues

    To investigate the prevalence of children with physical disabilities who used a computer-based ATD, and to examine characteristics differences in children and youths who do or do not use computer-based ATDs, as well as, investigate differences that might influence the satisfaction of those two groups of children and youths when computers are being used for in-school and outside school activities. A cross-sectional survey about computer-based activities in and outside school (n = 287) and group comparisons. The prevalence of using computer-based ATDs was about 44 % (n = 127) of the children in this sample. These children were less satisfied with their computer use in education and outside school activities than the children who did not use an ATD. Improved coordination of the usage of computer-based ATDs in school and in the home, including service and support, could increase the opportunities for children with physical disabilities who use computer-based ATDs to perform the computer activities they want, need and are expected to do in school and outside school.

    A biosimilar is a biological medicinal product claimed to be similar to a reference biological medicinal product. Its development plan includes studies comparing it with the reference product in order to confirm its similarity in terms of quality, preclinical safety, clinical efficacy, and clinical safety, including immunogenicity. Biosimilars differ from generics both in their molecular complexity and in the specific requirements that apply to them. Since patents on many biological medicinal products will expire within the next 5 years in major therapeutic areas such as oncology, rheumatology and gastroenterology and as those products are so costly to the French national health insurance system, the availability of biosimilars would have a considerable economic impact. The round table has issued a number of recommendations intended to ensure that the upcoming arrival of biosimilars on the market is a success, in which prescribing physicians would have a central role in informing and reassuring patients, an efficient monitoring of the patients treated with biologicals would be set up and time to market for biosimilars would be speeded up. © 2015 Société Française de Pharmacologie et de Thérapeutique.

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

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

    As a result of the Heavy Section Steel Technology Program (HSST), sponsored by the Nuclear Regulatory Commission, Westinghouse Electric Corporation conducted dynamic fracture toughness tests on irradiated HSST Plate 02 and submerged arc weldment material. Testing performed at the Westinghouse Research and Development Laboratory in Pittsburgh, Pennsylvania, included 0.394T compact tension, 1.9T compact tension, and 4T compact tension specimens. This data showed that, in the transition region, dynamic test procedures resulted in lower (compared to static) fracture toughness results, and that weak direction (WR) oriented specimen data were lower than the strong direction (RW) oriented specimen results. Irradiated lower-bound fracture toughness results of the HSST Program material were well above the adjusted ASME Section III K/sub IR/ curve. An irradiated and nonirradiated 4T-CT specimen was tested during a fracture toughness test as a preliminary study to determine the effect of irradiation on the acoustic emission-stress intensity factor relation in pressure vessel grade steel. The results indicated higher levels of acoustic emission activity from the irradiated sample as compared to the unirradiated one at a given stress intensity factor (K) level

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

    2009-10-01

    Over the last decades, the need to reduce emissions of greenhouse gases has prompted the development of technologies for the production of clean fuels through the use of primary energy resources of zero emissions, as the heat of nuclear reactors of high temperature. Within these technologies, one of the most promising is the hydrogen production by sulfur-iodine cycle coupled to a high temperature reactor initially proposed by General Atomics. By their nature and because it will be large-scale plants, the development of these technologies from its present phase to its procurement and construction, will have to incorporate emergency mitigation systems in all its parts and interconnections to prevent undesired events that could put threaten the plant integrity and the nearby area. For the particular case of sulfur-iodine thermochemical cycle, most analysis have focused on hydrogen explosions and failures in the primary cooling systems. While these events are the most catastrophic, is that there are also many other events that even taking less direct consequences, could jeopardize the plant operation, the people safety of nearby communities and carry the same economic consequences. In this study we analyzed one of these events, which is the formation of a toxic cloud prompted by uncontrolled leakage of concentrated sulfuric acid in the second section of sulfur-iodine process of General Atomics. In this section, the sulfuric acid concentration is near to 90% in conditions of high temperature and positive pressure. Under these conditions the sulfuric acid and sulfur oxides from the reactor will form a toxic cloud that the have contact with the plant personnel could cause fatalities, or to reach a town would cause suffocation, respiratory problems and eye irritation. The methodology used for this study is the supported design in probabilistic safety analysis. Mitigation systems were postulated based on the isolation of a possible leak, the neutralization of a pond of

    Full Text Available This article examines how the use of mobile technologies (iPods and tablets in language classrooms contributes to redesigning task-based approaches for young language learners. The article is based on a collaborative action research (CAR project in Early French Immersion classrooms in the province of Alberta, Canada. The data collection included digital ethnographic observation in the classrooms, students’ artifacts, and interviews with teachers and students. The findings outlined how the use of mobile technologies such as iPods and tablets contributes to redesigning language tasks and activities by helping young learners to create their own learning environment and meaningful language tasks, as well as self-assess and regulate their language learning process. The research also provides evidence of how the use of mobile technologies contributes to redesigning task-based approaches for young language learners that reflect learning principles based on emergent learning theories as well as Vygotskian sociocultural theories in second language acquisition (SLA.

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

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

    The radioactivity pacific and favourable applications are very numerous. The sensitivity, the efficiency of these processes make them peculiarly attractive. Nevertheless, their implementation is a demanding job on account of numerous subjects that must acquire the specialists: nuclear, electronic and computing, fluid mechanics and sometimes... athletics when it concerns studies on the maritime sites. In spite of these numerous advantages, we must not deduce that those methods are the panacea destined to replace the other technologies. It`s the association of these two approaches which is an economy and progress supply.

    To evaluate the geographic distribution of assisted reproductive technology (ART) clinics and the number of ART clinics within U.S. Census metropolitan areas and to estimate the number of reproductive-age women who have geographic access to ART services in the United States. A population-based cross-sectional study. Not applicable. None. None. Number of U.S. reproductive-age women living in areas with no ART clinic, a single ART clinic, or more than one ART clinic. There were 510 ART clinics in the United States in 2009-2013. Multiple ART clinics were present in 76 metropolitan areas (median population of 1.45 million people), where a total of 442 clinics were located. A single ART clinic was present in 68 metropolitan areas (median population of 454,000 people). Among U.S. reproductive-age women in 2010, 38.1 million (60.4% of the U.S. population) lived in an area with multiple ART clinics, 6.8 million (10.8% of the U.S. population) lived in an area with a single clinic, and 18.2 million (28.8% of the U.S. population) lived in an area (metropolitan and nonmetropolitan) with no ART clinics. Nearby geographic access to ART services is limited or absent for more than 25 million reproductive-age women (39.6% of the U.S. population) in the United States. This population estimate should spur continued policy and technological progress to increase access to ART services. Copyright © 2017 American Society for Reproductive Medicine.

    Digital technology has the potential to support teenagers and young adults (TYAs) with cancer from the onset of their disease into survivorship. We aimed to establish (1) the current pattern of use of TYA digital technologies within our service-user population, and (2) their preferences regarding digital information and support within the service. A cross-sectional survey was administered as a paper and online self-completed questionnaire to TYAs aged 13-24 accessing outpatient, inpatient, and day care cancer services at a regional specialist centre over a 4-week period. One hundred two TYAs completed the survey (55.7% male; 39.8% female; 83.3% paper; 16.7% online; mean age 18.5 years [SD = 3.51]). Of the TYAs, 41.6% rated the importance of digital communication as "essential" to their lives. Half (51.0%) kept in contact with other patients they had met during treatment, and 12.0% contacted patients they had not met in person. Respondents wanted to receive clinical information online (66.3%) and use online chat rooms (54.3%). Future online services desired included virtual online groups (54.3%), online counselling or psychological support (43.5%), and receiving (66.3%) and sharing (48.9%) clinical information online. Young people with cancer are digital natives. A significant subgroup expressed a desire for digital resources from oncology services, though existing resources are also highly valued. Digital resources have potential to improve patient experience and engagement. There is considerable scope to develop digital resources with which TYAs can receive information and connect with both professionals and fellow patients, following diagnosis, through treatment and survivorship.

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

    Full Text Available Purpose. The purpose of this study is to assess the frequency of use of information and communication technologies and patterns of preference among Ecuadorian patients with diabetes. Methods. We conducted an anonymous cross-sectional survey on type 2 diabetes mellitus. A chi-square test for association and adjusted regression analyses were performed. Results. 248 patients were enrolled, with a mean sample age of 57.7 years. SMS was the most used ICT (66.0%. The Internet was used by 45.2% of patients to obtain information about diabetes. SMS and email were rated as the most useful ICTs for receiving information (64.5% and 28.1%, resp. and asking physicians about diabetes (63.8% and 26.1%, resp.. Patients were also interested in receiving disease information (82.4% and asking physicians about diabetes (84.7% through WhatsApp. Adjusted logistic regressions revealed that individuals aged 55 years or younger, those with superior degree level, and those with long diabetes history preferred email for receiving information and asking physicians about diabetes compared to those above 55 years, those with low education level, and those with short diabetes history, respectively. Conclusion. Understanding preferences of ICTs among patients with diabetes could facilitate application development targeted towards specific requirements from patients.

    The aim of the present study was to assess the frequency of uses and preferences of information and communication technologies (ICTs) among Latin American chronic obstructive pulmonary disease (COPD) patients. We conducted an anonymous cross-sectional survey study on Latin American COPD patients. The adapted version of the Michigan questionnaire was employed in eligible outpatients in different cities of Latin America. We categorized age and educational levels into three groups. The time passed since COPD diagnosis was categorized as ≤5 years and >5 years. χ 2 and crude and adjusted logistic regressions were performed. A total of 256 patients were enrolled with a mean age of 68.7 years old. The most recurrently used ICTs were short message service (SMS; 47.1%) and WhatsApp (30.7%) for receiving COPD information. Moreover, SMS (85.8%) and Facebook (36.1%) were rated as useful for asking physicians information about COPD. Regression analysis showed that the best predictor for patients using ICTs, for any purpose, was higher education (undergraduate or graduate school). Understanding the preferences of ICTs among COPD patients could help improve patient's outcomes through developing applications in response to specific requirements of each patient.

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

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

    In the era of the knowledge economy, public health nurses (PHNs) need to update their knowledge to ensure quality of care. In pre-implementation stage, policy makers and educators should understand PHNs' behavioural intentions (BI) toward web-based learning because it is the most important determinant of actual behaviour. To understand PHNs' BI toward web-based learning and further to identify the factors influencing PHNs' BI based on the technology acceptance model (TAM) in pre-implementation stage. A nationwide-based cross-sectional research design was used in this study. Three hundred and sixty-nine health centres in Taiwan. A randomly selected sample, 202 PHNs participated in this study. Data were collected by mailing in a questionnaire. The majority of PHNs (91.6%, n=185) showed an affirmative BI toward web-based learning. PHNs rated moderate values of perceived usefulness (U), perceived ease of use (EOU) and attitude toward web-based learning (A). Multiple regression analyses indicated that only U revealed a significantly direct influence on BI. U and EOU had significantly direct relationships with A; however, no significant relationship existed between A and BI. Additionally, EOU and an individual's computer competence revealed significant relationships with U; Internet access at the workplace revealed a significant relationship with EOU. In the pre-implementation stage, PHNs perceived a high likelihood of adopting web-based learning as their way of continuing education. In pre-implementation stage, perceived usefulness is the most important factor for BI instead of the attitude. Perceived EOU, an individual's computer competency, and Internet access at workplaces revealed indirect effects on BI. Therefore, increasing U, EOU, computer competence, and Internet access at workplace will be helpful in increasing PHNs' BI. Moreover, we suggest that future studies should focus on clarifying problems in different stages of implementation to build a more complete

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

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

    The numerous research programmes looking at new-generation biofuels that were initiated over the last ten years are now starting to bear fruit. Although no plants are producing and marketing biofuels yet, the large-scale, industrial feasibility of second-generation bio-fuel production at competitive cost may be demonstrated in the short-term. As far as third generation biofuels derived from algal biomass are concerned, there is a great deal of R and D interest in the sector, but the technology is still only in its infancy. (author)

These demonstrators, built at scale 1, have been an essential support to the establishment of the 'Dossier 2005' which demonstrates the feasibility of a reversible disposal of long living-intermediate level and high level radioactive wastes in the Callovo-Oxfordian argillite of Meuse-Haute Marne. Two type of demonstrators were built: demonstrators of storage containers for long living-intermediate level wastes and for spent fuels, and dynamic demonstrators for containers handling. This brochure presents these different demonstrators, their characteristics and the results of their tests. (J.S.)

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

    Les estampes ont inspiré à Baudelaire des essais sur le rire et sur les caricaturistes français et étrangers, sans doute conçus dès 1846. Sa correspondance montre qu’il a connu Gavarni et qu’il fut proche d’Honoré Daumier. Après 1860, il fut en relation avec Charles Meryon et avec plusieurs aquafortistes d’avant-garde, Félix Bracquemond, Édouard Manet, Alphonse Legros, Johan Barthold Jongkind, James McNeill Whistler et Félicien Rops.

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

    We present a measurement of the tt production cross section in pp collisions at square root s = 1.96 TeV which uses events with an inclusive signature of significant missing transverse energy and jets. This is the first measurement which makes no explicit lepton identification requirements, so that sensitivity to W --> tau nu decays is maintained. Heavy flavor jets from top quark decay are identified with a secondary vertex tagging algorithm. From 311 pb(-1) of data collected by the Collider Detector at Fermilab, we measure a production cross section of 5.8 +/- 1.2(stat)(-0.7)(+0.9)(syst) pb for a top quark mass of 178 GeV/c2, in agreement with previous determinations and standard model predictions.

    Alcohol consumption at hazardous levels is more prevalent and associated with poor health outcomes among persons living with the human immunodeficiency virus (HIV; PLWH). Although PLWH are receptive to using technology to manage health issues, it is unknown whether a cell phone app to self-manage alcohol use would be acceptable among PLWH who drink. The objectives of this study were to determine factors associated with interest in an app to self-manage drinking and to identify differences in baseline mobile technology use among PLWH by drinking level. The study population included 757 PLWH recruited from 2014 to 2016 into the Florida Cohort, an ongoing cohort study investigating the utilization of health services and HIV care outcomes among PLWH. Participants completed a questionnaire examining demographics, substance use, mobile technology use, and other health behaviors. Multivariable logistic regression was used to identify factors significantly associated with interest in an app to self-manage drinking. We also determined whether mobile technology use varied by drinking level. Of the sample, 40% of persons who drink at hazardous levels, 34% of persons who drink at nonhazardous levels, and 19% of persons who do not drink were interested in a self-management app for alcohol use. Multivariable logistic regression analysis indicated that nonhazardous drinking (adjusted odds ratio [AOR] = 1.78; confidence interval [CI 95%]: 1.10-2.88) and hazardous drinking (AOR = 2.58; CI: 1.60-4.16) were associated with interest, controlling for age, gender, education, and drug use. Regarding mobile technology use, most of the sample reported smartphone ownership (56%), text messaging (89%), and at least one cell phone app (69%). Regardless of drinking level, overall mobile technology use among PLWH was moderate, whereas PLWH who consumed alcohol expressed greater interest in a cell phone app to self-manage alcohol use. This indicates that many PLWH who drink would be interested

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

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

    The standard model of particle physics describes the matter as elementary particles interacting via strong and electroweak interactions. The top quark is the heaviest quark described by this model and has been discovered in 1995 by CDF and D collaborations in proton-antiproton collisions at the Tevatron. This thesis is devoted to the measurement of the top pair production cross-section via the strong interaction, in a final state composed of one lepton, one hadronic tau, two b-jets and missing transverse energy. This analysis uses the 1,2 fb

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

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

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

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

    De Bonnis, Isabelle

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

    AUTHOR|(INSPIRE)INSPIRE-00387311; Schoeffel, Laurent

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

    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.

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

    A daily rest period (DRP; rest taken from daily work during a 24 h period), is essential to work recovery. This study examined DRPs' distribution and association with health outcomes among information technology workers recruited from an internet panel (N=1,811). Participants completed a web questionnaire examining psychological distress as a primary outcome, along with non-restorative sleep, fatigue (stress reaction), and work performance. Logistic regression analysis showed elevated psychological distress when DRP was sleep and fatigue, but not work performance, when DRP was <12 h. These findings constitute the first analysis of a dose-response relationship between DRP and subjective health outcomes among white-collar workers.

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

    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

    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

    Identifying group affinity from human crania is a long-standing problem in forensic and physical anthropology. Many craniofacial differences used in forensic skeletal identification are difficult to quantify, although certain measurements of the midfacial skeleton have shown high predictive value for group classifications. This study presents a new method for analyzing midfacial shape variation between different geographic groups. Three-dimensional laser scan models of 90 crania from three populations were used to obtain cross-sectional midfacial contours defined by three standard craniometric landmarks. Elliptic Fourier transforms of the contours were used to extract Fourier coefficients for statistical analysis. After cross-validation, discriminant functions based on the Fourier coefficients provided an average of 86% correct classifications for crania from the three groups. The high rate of accuracy of this method indicates its usefulness for identifying group affinities among human skeletal remains and demonstrates the advantages of digital 3D model-based analysis in forensic research. © 2011 American Academy of Forensic Sciences.

    To evaluate the reliability of RobotReviewer's risk of bias judgments. In this prospective cross-sectional evaluation, we used RobotReviewer to assess risk of bias among 1,180 trials. We computed reliability with human reviewers using Cohen's kappa coefficient and calculated sensitivity and specificity. We investigated differences in reliability by risk of bias domain, topic, and outcome type using the chi-square test in meta-analysis. Reliability (95% CI) was moderate for random sequence generation (0.48 [0.43, 0.53]), allocation concealment (0.45 [0.40, 0.51]), and blinding of participants and personnel (0.42 [0.36, 0.47]); fair for overall risk of bias (0.34 [0.25, 0.44]); and slight for blinding of outcome assessors (0.10 [0.06, 0.14]), incomplete outcome data (0.14 [0.08, 0.19]), and selective reporting (0.02 [-0.02, 0.05]).

  9. Promoting the International Transfer of Low-Carbon Technologies: Evidence and Policy Challenges. Report for the Commissariat general a la strategie et a la prospective (French Center for Policy Planning)

    The international diffusion of technologies with a potential to reduce carbon emissions is at the core of current climate change negotiations. North-to-South technology transfer is of particular importance since technologies have so far been mostly developed in industrialized countries, but are urgently required to mitigate greenhouse gas (GHG) emissions in fast-growing emerging economies. Against this background, the primary objective of this study is to give recommendations on how the transfer of low-carbon technologies could be promoted. Our contribution to the current debate is threefold. First, we provide an up-to-date picture of the climate-related technology transfer landscape, based on a combination of patent data, bilateral trade data and foreign investment data. Second, we develop and implement a methodology to identify which technologies should be given priority and which recipient countries should be targeted. Third, we discuss the potential of different policy approaches and the instruments available to promote technology transfer. The picture of technology diffusion is totally different for emerging economies and least-developed countries. The latter group of countries is hardly visible in the data simply because they do not import climate-mitigation technologies. In contrast, technologies are already flowing into emerging economies through market channels such as the import of capital goods, local investment by multinational enterprises that own technologies, and the associated circulation of skilled workers (about 16-30% of global transfer flows, depending on the indicator, a percentage in line with their contribution to world GDP). South-South technology transfer is, however, very limited, as technology providers are mostly located in industrialized countries. Several countries - China, South Africa, Mexico and, to a lesser extent, Brazil - seem particularly well connected to global technology flows. Fewer technologies are transferred towards other

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

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

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

    In resource-poor countries access to essential medicines, suboptimal prescribing and use of medicines are major problems. Health workers lack updated medical information and treatment support. Information and Communication Technology (ICT) could help tackle this. The impact of ICT on health systems in resource-poor countries is likely to be significant and transform the practice of medicine just as in high-income countries. However, research for finding the best way of doing this is needed. We aimed to assess current approaches to and use of ICT among health workers in two rural districts of Tanzania in relation to the current drug distribution practices, drug stock and continuing medical information (CME), as well as assessing the feasibility of using ICT to improve ordering and use of medicines. This pilot study was conducted in 2010-2011, mapping the drug distribution chain in Tanzania, including problems and barriers. The study was conducted in Bunda and Serengeti districts, both part of the ICT4RD (ICT for rural development) project. Health workers involved in drug procurement and use at 13 health facilities were interviewed on use and knowledge of ICT, and their attitudes to its use in their daily work. They were also shown and interviewed about their thoughts on an android tablet application prototype for drug stock inventory and drug ordering, based on the Tanzanian Medical Stores Department (MSD) current paper forms. The main challenge was a stable supply of essential medicines. Drug supplies were often delayed and incomplete, resulting in stock-outs. All 20 interviewed health workers used mobile phones, 8 of them Smartphones with Internet connection. The Health workers were very positive to the tablet application and saw its potential in reducing drug stock-outs. They also expressed a great need and wish for CME by distance. The tablet application was easily used and appreciated by health workers, and thus has the potential to save time and effort, reduce

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

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

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

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

    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.

    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.

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

    Data collection in Sub-Saharan Africa has traditionally been paper-based. However, the popularization of Android mobile devices and data capture software has brought paperless data management within reach. We used Open Data Kit (ODK) technology on Android mobile devices during a household survey in the Niger Delta region of Nigeria. The aim of this study was to describe the pros and cons of deploying ODK for data management. A descriptive cross-sectional household survey was carried out by 6 data collectors between April and May 2016. Data were obtained from 1706 persons in 601 households across 6 communities in 3 states in the Niger Delta. The use of Android mobile devices and ODK technology involved form building, testing, collection, aggregation, and download for data analysis. The median duration for data collection per household and per individual was 25.7 and 9.3 min, respectively. Data entries per device ranged from 33 (33/1706, 1.93%) to 482 (482/1706, 28.25%) individuals between 9 (9/601, 1.5%) and 122 (122/601, 20.3%) households. The most entries (470) were made by data collector 5. Only 2 respondents had data entry errors (2/1706, 0.12%). However, 73 (73/601, 12.1%) households had inaccurate date and time entries for when data collection started and ended. The cost of deploying ODK was estimated at US $206.7 in comparison with the estimated cost of US $466.7 for paper-based data management. We found the use of mobile data capture technology to be efficient and cost-effective. As Internet services improve in Africa, we advocate their use as effective tools for health information management. ©Omosivie Maduka, Godwin Akpan, Sylvester Maleghemi.

À ce jour, les données concernant les effets sur la composition corporelle chez l’homme semblent indiquer un bénéfice potentiel, mais les résultats restent controversés. Par ailleurs, bien qu’un effet anticarcinogène soit démontré chez l’animal, aucune étude chez l’homme n’a pu établir de relation entre CLA et cancer du sein. De plus, peu d’études traitant des aspects sécuritaires liés à la consommation à long terme ont été publiées. Par conséquent, il est nécessaire de disposer de plus de données en particulier chez l’Homme pour garantir l’innocuité de ces acides gras afin de protéger le consommateur, avant d’envisager l’utilisation de CLA dans des aliments fonctionnels.

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.

    Les preoccupations economiques et environnementales constituent des enjeux majeurs pour le developpement de nouvelles technologies en aeronautique. C'est dans cette optique qu'est ne le projet MDO-505 intitule Morphing Architectures and Related Technologies for Wing Efficiency Improvement. L'objectif de ce projet vise a concevoir une aile adaptative active servant a ameliorer sa laminarite et ainsi reduire la consommation de carburant et les emissions de l'avion. Les travaux de recherche realises ont permis de concevoir et optimiser une peau en composite adaptative permettant d'assurer l'amelioration de la laminarite tout en conservant son integrite structurale. D'abord, une methode d'optimisation en trois etapes fut developpee avec pour objectif de minimiser la masse de la peau en composite en assurant qu'elle s'adapte par un controle actif de la surface deformable aux profils aerodynamiques desires. Le processus d'optimisation incluait egalement des contraintes de resistance, de stabilite et de rigidite de la peau en composite. Suite a l'optimisation, la peau optimisee fut simplifiee afin de faciliter la fabrication et de respecter les regles de conception de Bombardier Aeronautique. Ce processus d'optimisation a permis de concevoir une peau en composite dont les deviations ou erreurs des formes obtenues etaient grandement reduites afin de repondre au mieux aux profils aerodynamiques optimises. Les analyses aerodynamiques realisees a partir de ces formes ont predit de bonnes ameliorations de la laminarite. Par la suite, une serie de validations analytiques fut realisee afin de valider l'integrite structurale de la peau en composite suivant les methodes generalement utilisees par Bombardier Aeronautique. D'abord, une analyse comparative par elements finis a permis de valider une rigidite equivalente de l'aile adaptative a la section d'aile d'origine. Le modele par elements finis fut par la suite mis en boucle avec des feuilles de calcul afin de valider la

Alors que les aînées d’aujourd’hui appartiennent à une génération de femmes qui ont ouvert de multiples portes et ont investi de nouveaux espaces publics, on s’est peu intéressé à leurs pratiques et au sens de leurs engagements après 65 ans. Après avoir introduit la question de la participation sociale et citoyenne des personnes âgées en général, et plus particulièrement des femmes âgées, les auteures mettent en évidence les principales caractéristiques de leurs engagements militants et de leurs conceptions du monde ; un monde qu’elles rêvent encore de changer. Une attention particulière est portée à la perception qu’ont les aînées des différences liées au genre et à la génération. En effet, bien que la plupart d’entre elles ne se définissent pas comme étant des retraitées ni des féministes, elles considèrent que leurs formes et leurs pratiques de militance se distinguent de celles des jeunes militantes et de leurs homologues masculins.Este artículo tiene como objetivo analizar la cuestión de la militancia de las mujeres mayores de 65 años. Propone un estudio llevado a cabo en Québec, Canadá, sobre un período de 3 años (2005-2008. Sabemos que las mujeres mayores de 65 años pertenecen a una nueva generación que ha abierto muchas puertas y se ha introducido en espacios públicos nuevos. Sin embargo, poco nos hemos interesado por sus actividades y sus compromisos después de los 65 años. En este estudio, se introducirá de forma general el problema de la participación social y ciudadana de las personas mayores para después comprobar las principales características de su militancia y de su concepción del mundo. Se prestará especial atención a la percepción que tienen estas mujeres de las

    1996-01-01

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

  14. Evapotranspiration (ET) covers.

    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.

    Full Text Available L’article expose les rapports de l’amitié et du plaisir en Grèce ancienne d’après les principes de l’anthropologie historique. Aussi, il travaille sur des « notions indigènes », qui s’inscrivent dans une constellation de notions, parmis lesquelles l’association de charis et philia. En admettant qu’on manque du matériau nécessaire à pousser à une conclusion définitive l’étude sur la charis et la philia chez les Grecs, c’est à dire, de l’individu, la personne, l’intériorité du moi, l’article tente de faire l’étude avancer, en s’appuyant sur quelques textes grecs, notamment ceux d’Arsitote. Pour le philosophe, la charis n’est pas une affection (pathos, à la différence de la philia, classée comme telle dans la Rhét. ; d’après l’EN, elle est « une vertu ou accompagnée de vertu ». Le « charitable » pourtant, relatif de la charis, est l’une des espèces de l’aimable qui est, à son tour, le relatif de l’amitié reposant sur le plaisir. Après quelques démarches, l’article montre comment la relation visuelle occupe une place fondamentale dans la conception aristotélicienne de charis et de philia.

    Les avancées considérables de la physique d'après guerre n'ont - on le sait - été possibles qu'au prix d'une vraie rupture entre elle et la physique dite " classique ". A quels changements cette rupture nous contraint-elle en ce qui concerne des notions essentielles, telles celles d'espace, de temps, d'objet et d'objectivité ? Quelles en sont les incidences quant à la portée de la connaissance, au rôle de la conscience, aux relations entre science et ontologie ? Ce sont là des questions de fond, fort délicates, auxquelles les personnes de tendance quelque peu philosophique sont plus sensibles que ne le sont les physiciens. Malheureusement, les premières ne disposent normalement pas des connaissances de pointe qui seules permettent d'approfondir de tels problèmes sans trop risquer de s'égarer. Etant donné l'impact que, par ses applications, la science a sur nos vies, nombreux sont ceux qui souhaitent se former une idée plus juste de ce qu'elle implique vraiment.

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

    2006-04-01

    Full Text Available Les opérations de requalification des centres des petites villes se sont multipliées depuis deux décennies. Cet article analyse comment le réaménagement des centres-villes s’inscrit dans un processus de patrimonialisation qui participe à une nouvelle conception de l’urbanité à travers une mise en scène des espaces centraux. Cette mise en scène des espaces publics passe par la multiplication de signes d’ancienneté. On peut distinguer des modalités différentes selon que les artefacts mobilisés renvoient à l’histoire du lieu, à des éléments hérités du passé et réinscrits dans l’espace ou qu’ils relèvent d’une ancienneté générique telle qu’elle s’est popularisée dans l’usage des mobiliers urbains « de style » — comme les candélabres « tradition » et bornes en fonte symbolisant l’appartenance à une urbanité d’apparence. Ce phénomène identitaire particulier vise à produire une urbanité, au moins physique. Cette artefactualisation amène à une redéfinition de la patrimonialisation. La tendance actuelle à la substitution d’« objets patrimoines » par des signes rappelant leur existence passée et les artefacts simulant de l’ancienneté et suscitant de l’historicité mobilisent les notions d’ambiance, d’esthétique et de « simulacre » selon le terme utilisé par Jean Baudrillard. La combinaison des références au patrimoine local et à l’ancien générique participe d’une mise en scène plus globale visant à inscrire le centre dans le temps long et à la production esthétique d’une néo-archéo urbanité « petite ville ». Refitting operations of downtown areas of small cities have increased for two decades. This article analyzes how this restructuring falls under a process of “patrimonialisation” which takes part in a new design of “urbanity” through a setting in scene of central spaces. This setting in scene of public spaces finds expression in

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

    Larrue, Ph.

    2000-05-23

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

    Marks, Stephen P

    2014-12-01

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

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

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

    Full Text Available On s'interrogera, dans cet exposé, sur les conditions nécessaires, tant au plan théorique qu'au plan méthodologique, pour que la prise en compte de la dimension diachronique par la linguistique textuelle puisse constituer une discipline dotée de ses notions et de ses problématiques propres, de la même façon que la spécificité de l'approche diachronique sait être reconnue lorsqu'il s'agit de phonétique, de morphosyntaxe ou de sémantique. Si bon nombre d'études existent déjà dans certains sous-domaines (on peut par exemple évoquer le discours rapporté, le fonctionnement des expressions anaphoriques ou le rôle des temps verbaux, on soulignera le fait que, dans la plupart des cas, les phénomènes ne sont pas vraiment étudiés dans une perspective de linguistique textuelle. Il suffirait de citer les travaux, relativement nombreux, sur la pragmaticalisation, sur l'évolution des modalisateurs, des marqueurs de topicalisation, par exemple, qui constituent en fait des applications de la théorie de la grammaticalisation, des illustrations d'opérations comme la réanalyse et l'analogie. Tout se passe comme si les faits de linguistique textuelle étaient utilisés dans une autre optique, comme si la dimension diachronique conduisait à donner la priorité à l'étude des mécanismes du changement. Notre objectif sera d'insister ici sur quelques problématiques transversales, qu'une approche souvent trop restreinte a quelque peu occultées et qui demeurent implicites, mais qu'il conviendrait de prendre en compte si on a pour objectif la construction d'une discipline bien identifiée. Il est vrai qu'indépendamment de la question de la diachronie, la linguistique textuelle présente de nombreuses facettes ; cela ne nous semble cependant pas empêcher la reconnaissance de problèmes généraux, qui se posent quelles que soient les approches adoptées.

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

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

    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.

    Feedback bliver i litteraturen igen og igen fremhævet som et af de mest effektive midler til at fremme elevers præstationer i skolen (Hattie og Timperley, 2007). Andre studier er dog inde på at feedback ikke altid er læringsfremmende og nogle viser endda at feedback kan have en negativ virkning i...... forhold til præstationer (Kluger & DeNisi, 1996). I forsøget på at forklare hvordan og hvorfor feedback virker (forskelligt), er der undersøgt flere dimensioner og forhold omkring feedback (se bl.a.

Praksis...... (den er ireversibel), den involverer en tids- og rumlig dimension og rytme (krop/materialitet, fortid, nutid og fremtid er nærværende hele tiden). Men praksis er ikke helt tilfældig og astruktureret, den følger en logik, den er strategisk, rettet og også kreativ – improviserende. Ydmyghed om hvad teori...... og praksis er I stedet for disse kontinuitetskonstruktioner om teori-praktik, kunne man på universitet, højskole og arbejdsliv, træne lærere og studerende i at teori er redskab til at tænke gennem, til at forstå dimensioner af det sociale eller naturlige.

    Full Text Available This case study, which provides an interim report of the research conducted, describes the changes experienced by teachers after participating for three months in a project to integrate information and communications technologies (ICT into an Ontario secondary school. The goal was to determine what changes occurred and what factors either fostered or impeded them. The participating teachers perceived active leadership in the school and social pressure to be the emergent positive change factors. On the other hand, they viewed a lack of available tools, time, and anxiety as being the main constraints. Profound changes in the roles of the teacher and the student were also noted during this period, changes that the teachers attributed to the integration of ICT into the curriculum.

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

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

    Houde, Sylvie

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

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

    Full Text Available Vingt et une espèces de Gyrodactylus de Salmonidae arrangées en six groupes sont présentées. Les observations concernant ces espèces dans les milieux naturels et en pisciculture sont résumées. Sur la base de données générales relatives aux espèces de Gyrodactylus en milieu naturel en Scandinavie et Baltique, les observations biologiques, écologiques et comportementales de G. salaris Malmberg, 1957 et G. derjavini MALMBERG et MALMBERG (1987 des salmonidae sauvages des rivières norvégiennes et suédoises sont présentées. La viviparité unique, la reproduction asexuée et sexuée et le pouvoir de reproduction chez les Gyrodactylus sont développés. La Gyrodactylose à G. salaris est abordée en milieu naturel, dans les rivières norvégiennes et en pisciculture, en Suède et au Danemark. L'étude ultrastructurale des blessures causées par G. salaris ainsi que les résultats expérimentaux sur les espèces norvégiennes et canadiennes sont présentés. La distribution géographique naturelle des Salmonidae, les modifications liées à l'homme et à l'activité économique ainsi que les Salmonidae élevés sont revus. La présence de six groupes d'espèces de Gyrodactylus en Amérique du Nord et Eurasie est discutée en fonction de la distribution géographique des espèces hôtes. Il est souligné qu'une propagation intercontinentale des espèces de Gyrodactylus de Salmonidae a dû être impossible à cause de leur origine limnique d'une part et de la salinité élevée des océans atlantique et pacifique d'autre part. Les exigences micro et macro environnementales des espèces sont discutées dans les conditions naturelles et les variations saisonnières, préférendums et tolérances du parasitisme sont signalés. L'effet des conditions de pisciculture sur les espèces de Gyrocactylus sont discutées : la capacité reproductrice et de propagation ainsi que la spécificité — stricte dans la nature — peuvent être influenc

    The Section is concerned with preparation of environmental statements and assessments and development of assessment methodologies for energy technologies. During 1976, activities involved nuclear, fossil, and geothermal energy; this work was supported by the U.S.Army, HUD, US ERDA, and US NRC. Two special studies--one on the effects of power plant intake structures on fish impingement and another on multiple uses of cooling lakes--were completed and should serve as references for future analyses. Two research projects sponsored by NRC--the Unified Transport Approach (UTA) to Power Plant Assessment and the Environmental Monitoring Data Evaluation Study--were continued. The purpose of the UA program is to develop fast-transient, one- and two-dimensional transport models for estimating thermal, radiological, chemical, and biological impacts in complicated water bodies. The impact of public use of various products that contain radioactive isotope is being evaluated. The Environmental Impact Sections assistance to NRC expanded to include assessments of fuel-fabrication facilities being considered for relicensing and two uranium in-situ solution mining facility proposals. The work for HUD comprises an assessment of the first application of MIUS in a new town development. A generic environmental statement was prepared and an environmental monitoring program for the facility was designed

    To better understand practice patterns and opportunities for standardization of ET. Cross-sectional survey. Not applicable. Not applicable. An anonymous 82-question survey was emailed to the medical directors of 286 Society for Assisted Reproductive Technology member IVF practices. A follow-up survey composed of three questions specific to ET technique was emailed to the same medical directors. Descriptive statistics of the results were compiled. The survey assessed policies, protocols, restrictions, and specifics pertinent to the technique of ET. There were 117 (41%) responses; 32% practice in academic settings and 68% in private practice. Responders were experienced clinicians, half of whom had performed technique. Multiple steps in the ET process were identified as "highly conserved;" others demonstrated discordance. ET technique is divided among [1] trial transfer followed immediately with ET (40%); [2] afterload transfer (30%); and [3] direct transfer without prior trial or afterload (27%). Embryos are discharged in the upper (66%) and middle thirds (29%) of the endometrial cavity and not closer than 1-1.5 cm from fundus (87%). Details of each step were reported and allowed the development of a "common" practice ET procedure. ET training and practices vary widely. Improved training and standardization based on outcomes data and best practices are warranted. A common practice procedure is suggested for validation by a systematic literature review.

  18. Special section on biomimetics of movement.

    2011-12-01

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

    2001-12-01

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

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

    Larsson Lund, Maria; Nygård, Louise; Kottorp, Anders

    2014-01-01

    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.

The Team's transfer activities for ongoing projects with the NASA Centers are presented in Section 5.0. Section 6.0 summarizes the status of four add-on tasks. Travel for the reporting period is described in Section 7.0. The RTI Team staff and consultants and their project responsibilities are listed in Appendix A. The authors gratefully acknowledge the contributions of many individuals to the RTI Technology Applications Team program. The time and effort contributed by managers, engineers, and scientists throughout NASA were essential to program success. Most important to the program has been a productive working relationship with the NASA Field Center Technology Utilization (TU) Offices. The RTI Team continues to strive for improved effectiveness as a resource to these offices. Industry managers, technical staff, medical researchers, and clinicians have been cooperative and open in their participation. The RTI Team looks forward to continuing expansion of its interaction with U.S. industry to facilitate the transfer of aerospace technology to the private sector.

    Passer en revue les connaissances scientifiques actuelles et formuler des recommandations relatives au diagnostic et à la prise en charge de la torsion annexielle chez les filles, les adolescentes et les femmes adultes. L'étude porte sur les facteurs de risque, la précision diagnostique, les options de prise en charge et les issues de la torsion annexielle. RéSULTATS: Nous avons examiné les études publiées en faisant des recherches dans MEDLINE, Embase, CINAHL et la Bibliothèque Cochrane à l'aide d'une terminologie contrôlée et de mots-clés appropriés (« adnexal torsion », « ovarian torsion »). Nous avons limité les résultats aux revues systématiques, aux essais contrôlés aléatoires, aux essais cliniques contrôlés et aux études d'observation. Nous avons refait les recherches de façon régulière et intégré de nouvelles données à la directive jusqu'en décembre 2014. Nous avons également étudié la littérature grise (non publiée) trouvée sur les sites Web d'organismes d'évaluation des technologies de la santé et d'autres organismes connexes, dans des collections de directives cliniques et dans des registres d'essais cliniques, et obtenue auprès d'associations nationales et internationales de médecins spécialistes. Les résultats ont été examinés et évalués par le comité CANPAGO de la Société des obstétriciens et gynécologues du Canada (SOGC), sous la direction des auteures principales. Les recommandations ont été classées selon les critères établis par le Groupe d'étude canadien sur les soins de santé préventifs. AVANTAGES, DéSAVANTAGES ET COûTS: L'application de la directive devrait aider les praticiens à adopter une approche de diagnostic et de prise en charge optimale en matière de torsion annexielle, à réduire au minimum les effets néfastes et à améliorer l'issue qui attend les patientes. La présente directive a été évaluée et approuvée par le Comité de pratique - gynécologie de la SOGC

    Le miel est la première image qui vient en tête à l’écoute du mot « abeille ». Pourtant, le miel que nous consommons est produit par une seule espèce, l’abeille mellifère (Apis mellifera), tandis que le mot « abeille » cache en réalité une multitude d’autres espèces très diversifiées et indispensables pour garantir le fonctionnement des écosystèmes et les rendements agricoles.

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

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

    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...

    The technology activities carried out by the Euratom-ENEA Association in the framework of the European Fusion Development Agreement concern the Next Step (International Thermonuclear Experimental Reactor - ITER), the Long-Term Programme (breeder blanket, materials, International Fusion Materials Irradiation Facility - IFMIF), Power Plant Conceptual Studies and Socio-Economic Studies. The Underlying Technology Programme was set up to complement the fusion activities as well to develop technologies with a wider range of interest. The Technology Programme mainly involves staff from the Frascati laboratories of the Fusion Technical and Scientific Unit and from the Brasimone laboratories of the Advanced Physics Technologies Unit. Other ENEA units also provide valuable contributions to the programme. ENEA is heavily engaged in component development/testing and in design and safety activities for the European Fusion Technology Programme. Although the work documented in the following covers a large range of topics that differ considerably because they concern the development of extremely complex systems, the high level of integration and coordination ensures the capability to cover the fusion system as a whole. In 2004 the most significant testing activities concerned the ITER primary beryllium-coated first wall. In the field of high-heat-flux components, an important achievement was the qualification of the process for depositing a copper liner on carbon fibre composite (CFC) hollow tiles. This new process, pre-brazed casting (PBC), allows the hot radial pressing (HRP) joining procedure to be used also for CFC-based armour monoblock divertor components. The PBC and HRP processes are candidates for the construction of the ITER divertor. In the materials field an important milestone was the commissioning of a new facility for chemical vapour infiltration/deposition, used for optimising silicon carbide composite (SiCf/SiC) components. Eight patents were deposited during 2004

    L'Homme a su coller avant de savoir écrire et compter. Le collage est en effet l'une des premières techniques d'assemblage d'une structure que l'homme ait utilisée, technique qui n'est devenue science qu'au début du 20e siècle avec la fabrication des premières colles synthétiques. Cette science de l'adhésion a considérablement progressé ces dix dernières années et ce livre présente l'état actuel des connaissances en décrivant les progrès considérables réalisés dans la compréhension des phénomènes fondamentaux qui font qu'un collage tient bien et durablement. Après l'exposé des bases scientifiques nécessaires et des modèles théoriques récents, l'auteur introduit la distinction entre collages faibles et collages forts puis expose les difficultés rencontrées dans les cas pratiques, difficultés souvent dues à la complexité de la chimie des surfaces et des réactions surface-polymère. L'ouvrage se termine par la présentation de quelques applications récentes, en particulier dans...

  19. 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
