    This dossier gathers a series of short articles about energy security and efficiency in a context of policy transition. The first paper deals with the use of international standards to promote energy efficiency thanks to efficient public policies and private sector actions. This was the main topic of the mixed workshop organized by the International electrotechnics Commission (IEC) in spring 2009. The second paper presents the new strategic analysis of the European commission in the domain of energy which stresses on the '20-20-20' climate change proposals approved in December 2008. A new European action plan for energy security and solidarity defines 5 domains requiring an extra action to warrant a sustainable energy supply. The commission is also examining the challenges that Europe will have to face between 2020 and 2050. The third article treats of the security of natural gas supplies which represents a quarter of the European Union (EU) energy mix. The supply crises susceptible to occur may have serious economic and social consequences. Therefore, the EU must be prepared to warrant its security of supplies. Cogeneration allows the EU to stay close to its energy goals. Buildings play a key role in the realisation of the EU's energy saving objectives and fight against climate change. The new directive on buildings energy efficiency (2002/91/CE) will allow to exploit this potential of saving and to stimulate sustainable investment and employment as well. Finally, the publication of the second WBCSD (World business council for sustainable development) international report on buildings energy efficiency has led GDF Suez utility to reaffirm its commitment in favour of energy saving and efficiency.

  4. Le rapport au savoir scientifique d'enseignantes et d'enseignants du primaire

    Plonczak, Irene

    Nous avons procede a l'examen de problemes relatifs a l'education aux sciences via une approche a caractere epistemologique, contrairement a l'approche plus usuelle qui aborde les difficultes des apprenants a composer avec les connaissances dites scientifiques seulement d'un point de vue cognitif. La question de recherche que nous nous sommes posee a ete la suivante: Quel est le rapport au savoir scientifique d'enseignantes et d'enseignants du primaire? Pour repondre a cette question sur le plan methodologique, nous avons envisage l'etude du rapport au savoir scientifique d'enseignantes et d'enseignants dans un contexte relie a leur savoir et a leur expertise de tous les jours. Nos modalites de cueillette de donnees ont ete le recit ecrit et l'entrevue individuelle semi-structuree. Notre recherche a pris la forme d'une etude de cas multiples conduisant a l'etude des rapports epistemique, pratique et identitaire au savoir scientifique de dix enseignantes et enseignants d'ecoles populaires de Caracas, au Venezuela. Nos analyses nous ont amenee a affirmer que les sujets ont manifeste un rapport au savoir scientifique domine par la dependance et la soumission a l'egard des sciences ainsi que d'autres caracteristiques propres a une approche empirico-realiste. Cependant, dans un contexte relie a leur savoir-faire et a leur expertise, nous avons repere des traces de l'emergence d'une vision des sciences qui tient compte, entre autres, du caractere social de la production de ces dernieres, ce qui pourrait se qualifier comme faisant partie d'une tendance epistemologique du type socioconstructiviste. En plus, nos analyses nous amenent a suggerer que dans ce contexte les sujets auraient egalement initie une articulation entre leur savoir-faire et le savoir scientifique, ce qui les aurait amenes a vehiculer un rapport plus emancipatoire vis-a-vis les sciences. Cette articulation des savoirs permet egalement d'envisager des experiences educatives plus creatives, plus

    2006-07-01

    Full Text Available Le travail à domicile est une organisation ancienne. Il se décline dans une série d’activités salariées ou indépendantes, réalisées pour partie ou en totalité dans l’espace domestique. Le télétravail à domicile, basé sur l’utilisation de l’informatique et des technologies de l’information et de la communication, en représente un aspect moderne. Il redéfinit les frontières spatio-temporelles qui ont fortement structuré le monde du travail. Obligeant souvent à une forte implication, valorisé pour la liberté et la créativité, questionnant la séparation des sphères professionnelle et privée, le télétravail à domicile, lorsqu’il est pratiqué par des populations qualifiées et amatrices d’autonomie, peut être considéré comme emblématique des transformations contemporaines du rapport au travail et du rapport à l’emploi. Cette thématique mêle des enjeux transversaux et nous interroge sur l’évolution des modes de vie, sur de nouvelles figures de l’autorité et sur de nouvelles formes de recherche du bonheur au travail.Home work is an old type of organization. It corresponds to many activities which are salaried or independent and which are realized partially or entirely in domestic space. Home telework, using ICT, represents a modern form of home work. It changes space-time frontiers which have traditionally characterized work organization. It can require a strong implication, it can bring freedom and creativity, it questions the frontiers between work and non work: home telework, concerning qualified people who want autonomy, can be regarded as a symbol of contemporary transformations of work and employment. Theses themes question us about new ways of life, about the evolution of authority, and about happiness in working life.

    Full Text Available Signer un contrat de travail c’est convenir de louer à une entreprise, contre rétribution, une partie de son temps personnel. Cet usage est borné par la loi, les accords de branche et les accords d’entreprise. Mais, dans certaines conditions, pour certaines raisons et pour des motivations jugées plus ou moins personnelles, un travailleur peut faire des « gratuités » et des arrangements exorbitants au regard de la réglementation et semble-t-il, en accord avec ses propres principes et valeurs… C’est ce que nous nommons le rapport au temps. D’où, en signalant que l’emploi du temps individuel et sa rétribution constituent les principaux objets de transaction dans le monde salarial, on conçoit donc que le rapport au temps est l’élément structurant de la culture professionnelle. Celle-ci correspond à un ensemble de prescriptions et/ou de proscriptions, de manières de se comporter, d’agir… relevant a priori d’un bon sens (professionnel partagé par les membres d’un groupe professionnel. Cette culture professionnelle amalgame, englobe et transcende les cultures spécifiques d’entreprise. Chez les agents d’animation, par exemple, quel que soit l’employeur, chacun trouve « normal » de travailler dans un temps scandé et « déritualisé », haché et fragmenté, bref décalé de la temporalité sociale dominante, là où, ailleurs, dans un autre domaine d’activité, cette situation aurait été jugée inacceptable ou refusée… De même que l’animateur attend que son travail lui donne plaisir et respecte sa vie personnelle, ce qui n’est pas forcément vrai chez le salarié ordinaire.Sociography of a « culture of time » as a foundation of professional cultureThe example of sociocultural officersWorking for a company means renting to it for money a part of a personal time.

    2012-05-01

    Full Text Available Les sociétés contemporaines connaissent un accroissement des inégalités, en termes de richesse et d’accès au pouvoir. Le fait gestionnaire, par son emprise croissante, joue un rôle particulièrement important dans l’actualisation des rapports de domination. Il se situe, en effet, à l'articulation entre les décisions politiques majeures et les transformations des sphères d'activité sociale. Mais c'est aussi par le renouvellement permanent de ses différentes composantes que le fait gestionnaire agit : procédant par expérimentations successives, il assure ainsi la perpétuation de rapports de domination, au cœur même des sphères économiques et professionnelles. Pour montrer la pertinence de cette approche, l’article élabore, dans le prolongement des acquis de la sociologie du travail, un modèle pour analyser la volonté gestionnaire de changer. En appliquant ce modèle à un vaste éventail de contextes professionnels, nous pointons et expliquons les effets de polarisation sociale qu’engendre cette volonté.The constant change at the heart relations oh dominationContemporary societies are experiencing growing inequalities in wealth and access to power. The process of “managerialism”, by its increasing influence, plays a particularly important role in updating the relations of domination. It is, indeed, located at the joint between the major policy decisions and changes in social spheres. But this process acts also by the constant renewal of its various components: proceeding by successive experiments, it ensures the perpetuation of relations of domination, at the heart of economic and professional spheres. To show the relevance of this approach, the paper develops, following the achievements of the sociology of work, a model to analyze the managerial will of change. Applying this model to a wide range of advanced professional contexts, we point out and explain the effects of social polarization generated by this will

    Full Text Available L’objectif de cette communication est de comparer sur le plan pédagogique deux conceptions du rapport entre science et vivant, diamétralement opposées sur le plan épistémologique. En se basant sur un livre [1], une conférence [2] et un entretien [3], on analysera l’expérience de pensée par laquelle le biologiste et épistémologue Jean-Jacques Kupiec fait se sentir vivants les apprenants afin de mieux les conscientiser aux réquisits de la démarche scientifique. On comparera ensuite les motivations de Kupiec avec les idées pédagogiques du philosophe-médecin Georges Canguilhem (1904–1995 afin d’essayer de comprendre pourquoi l’un et l’autre jugent pertinent de faire remarquer à l’apprenant qu’il est actuellement en vie. Car, malgré des conceptions du vivant diamétralement opposées, Canguilhem et Kupiec se rejoignent sur l’idée que l’expérience vitale joue un rôle crucial – que ce soit en positif ou en négatif, comme un obstacle épistémologique ou comme un levier heuristique – dans l’apprentissage et la pratique de la biologie ou de la médecine. Prendre en charge cette expérience constitue peut-être une ressource face au double défi (scientifique et éthico-politique qui échoit à l’éducation aux sciences du vivant.

Ce rapport d'étape fournit un aperçu du cadre socioécologique qui guide actuellement nos efforts de suivi de l'embonpoint et de l'obésité chez les enfants. Ce cadre intègre différents facteurs de risque et de protection (facteurs sociodémographiques, liés au mode de vie, psychosociaux et en début de vie et tient compte de l'étape de vie, des niveaux d'influence et de l'environnement au sein desquels ces facteurs jouent un rôle. Méthodologie : Nous avons effectué des analyses univariées et bivariées fondées sur les données de l'Enquête sur la santé dans les collectivités canadiennes et de l'Enquête canadienne sur les mesures de la santé pour rendre compte des facteurs comportementaux, des facteurs psychosociaux et des facteurs en début de vie associés à un surplus de poids chez les enfants canadiens. Résultats : Les estimations liées aux facteurs en début de vie (p. ex. l'allaitement, aux facteurs comportementaux (p. ex. l'activité physique et aux facteurs psychosociaux (p. ex. le sentiment d'appartenance à la collectivité sont présentées en fonction du groupe d'âge, du sexe, de la suffisance du revenu et du poids. Conclusion : Cette étude, qui s'appuie sur notre publication récente sur les tendances en matière d'obésité chez les enfants au Canada et les facteurs sociodémographiques qui y sont associés, présente les facteurs de risque et de protection intégrés à notre cadre de surveillance.

    This report for the Swiss Federal Office of Energy presents in tables and diagrams the results of a survey involving 421 households in Switzerland, about their awareness to energy issues and, in particular, to all what regards wind energy and wind power plants. Globally, 80% of the persons asked for their opinion believe that electric power demand will continue to increase. 66% of them are in favour of increased use of renewable energy sources and would consequently agree with a 10% more expensive end-user energy price. 89% of the persons taking part to the survey approve the installation of wind energy farms in Switzerland. Moreover, statistics indicates that the households living in regions already equipped with wind farms are significantly more favorable to the creation of new wind energy sites than those not living in these regions. By the end of the day, it turns out that the main reasons for accepting wind energy are environmental concerns as well as the fear of being obliged to use nuclear power. [French] Ce rapport presente par des graphiques et des tableaux le resultat d'un sondage d'opinion aupres de 421 menages en Suisse, sur la sensibilite du public aux problemes de l'energie et plus particulierement sur sa perception de tout ce qui concerne l'energie du vent et son exploitation par l'implantation d'eoliennes.

    CERN Document Server

    AUTHOR|(CDS)2091894; Giovinazzo, Jérôme

    Les études de la radioactivité bêta dans les milieux nucléaires permettent en partie de participer à la détermination d’un des paramètres qui décrit l'interaction faible (la constante de couplage vectoriel). Pour cela, de nombreuses mesures permettent déjà d’atteindre de grandes précisions sur ce paramètre pour un grand nombre de noyaux des transitions bêta super-permise. Cependant, pour le carbone 10, l'incertitude relative du rapport d'embranchement reste encore élevée par rapport aux autres noyaux pères avec une valeur de l’ordre de 0,13 %. Ceci est dû à l’énergie du photon émis par l’état 0+ du noyau fils qui est de 1021,6 keV, c’est-à-dire proche de l’énergie d’empilement de deux signaux de photons de 511 keV. En mai 2015, notre groupe a réalisé, à ISOLDE au CERN, une expérience afin de mesurer très précisément cette transition.

    On February 25, 2006, the French government took the decision of merging together Gaz de France and Suez energy companies as an answer to Enel's project of takeover bid on Suez. This document wonders about: the real motivations of Gaz de France (the French gas utility) privatization, the possible intervention of public authorities in Enel and Veolia companies project of controlling the Suez group, the governing way of the share-holding government and the preservation of its industrial interests, and the consequences for consumers. Therefore, the creation of a parliamentary inquiry commission is requested to shade light on these different points and to give notice of any bad practices in this affair. (J.S.)

Couture-Grondin suggère alors que les discours interculturels doivent tenir compte de la matérialité du racisme, qui continue d’affecter nos relations, et de la matérialité de l’écriture, qui permet de reconnaître la positionalité des discours et la particularité des traditions intellectuelles et de création autochtones.

    OpenAIRE

    James M. Boughton

    2000-01-01

    Egypt's nationalization of the Suez Canal in 1956 and the failed attempt by France, Israel, and the United Kingdom to retake it by force constituted a serious political crisis with significant economic consequences. For the United Kingdom, it engendered a financial crisis as well. That all four of the combatants sought and obtained IMF financial assistance was highly unusual for the time and had a profound effect on the development of the IMF. This case study illustrates the complexities in i...

    1981-01-01

    As the health care system is staffed by more and more professionals, the need for more supportive type leadership based on referent power will increase. In order to achieve the goals of the organization, leaders must begin to rely on their ability to communicate "themselves" to others, rather than on their coercive or legitimate power. Rapport (through empathy, respect, and warmth) is suggested as a means of influencing the attitudes of others and developing supportive leadership capabilities. The ever increasing professionalization of radiologic technology will necessitate more supportive type leadership both in the work place and within professional organizations.

    2014-01-01

    Full Text Available Introduction: The 5 th millennium development goal aims at reducing maternal mortality by 75% by the year 2015. According to the World Health Organization, there was an estimated 358,000 maternal deaths globally in 2008. Developing countries accounted for 99% of these deaths of which three-fifths occurred in Sub-Saharan Africa. In primary health care (PHC, quality of antenatal care is fundamental and critically affects service continuity. Nevertheless, medical research ignores the issue and it is lacking scientific inquiry, particularly in Egypt. Aim of the Study: The aim of the following study is to assess the quality of antenatal care in urban Suez Governorate, Egypt. Materials and Methods: A cross-sectional primary health care center (PHCC based study conducted at five PHCC in urban Suez, Egypt. The total sample size collected from clients, physicians and medical records. Parameters assessed auditing of medical records, assessing provider and pregnant women satisfaction. Results: Nearly 97% of respondents were satisfied about the quality of antenatal care, while provider′s satisfaction was 61% and for file, auditing was 76.5 ° 5.6. Conclusion: The present study shows that client satisfaction, physicians′ satisfaction and auditing of medical record represent an idea about opportunities for improvement.

  7. Two offshore LNG terminals planned by Suez in the USA; Suez prepare deux terminaux offshore aux Etats-Unis

    Energy Technology Data Exchange (ETDEWEB)

    Lepetit, V

    2006-02-15

    The US LNG market represents today only 15 million tons per year but it is growing up rapidly and should reach 75 million tons per year in the next ten years. According to Cambridge Energy Research, LNG imports will represent 18% of the US gas resources in 2015 with respect to 3% today, and in 2010 LNG will represent 30% of the world natural gas trade. For these reasons, the Suez group has planned to acquire two offshore gas terminals, i.e. LNG tanker ships fitted with a gasification plant, to supply its Everett terminal on the US East coast and a future terminal in Florida. In both cases, the investment is the same as for an onshore terminal facility. Short paper. (J.S.)

    Heavy ions having interesting properties as Bragg's peak require an important energy in order to attain a deep tumor. At intermediate and relativist energies, fragmentation reactions occur throughout their path and produce fragments lighter than the projectile. Consequently, the product fragments give a residual dose beyond the Bragg peak. For these reasons, the interesting ions in radiotherapy of cancer converge toward heavy light ions (C - Ne). Moreover, for a better treatment safety, it is envisaged also to use β(+) transmitting radioactive ion beams. This allows to provide the picture of the really irradiated volume by using a positon camera. In this context, our works essentially is concentrated on production rates and cross sections calculations for nucleus products in the fragmentation of (12)C at 95 MeV/u and (13)C at 75 MeV/u. Les ions lourds possédant des propriétés balistiques importantes tel que le pic de Bragg nécessitent une énergie importante pour atteindre une tumeur profonde. Aux énergies intermédiaires et relativistes, des réactions de fragmentation se produisent tout au long de leur trajet et donnent naissance à des fragments plus légers que le projectile. Ces derniers entraînent une dose résiduelle au-delà du pic de Bragg. Pour cette raison, les ions les plus intéressants en radiothérapie convergent vers les ions lourds - légers (C à Ne). Par ailleurs, pour une sécurité accrue du traitement, on envisage d'utiliser aussi des faisceaux d'ions radioactifs émetteurs β(+). Ceci permet de fournir l'image du volume réellement irradié en utilisant une caméra à positon. Dans ce contexte, nos travaux ont porté essentiellement sur le calcul de taux de production et de la section efficace des noyaux issus de la fragmentation du (12)C à 95 MeV/u et du (13)C à 75 MeV/u.

  5. Cost estimate for a proposed GDF Suez LNG testing program

    At the request of GDF Suez, a Rough Order of Magnitude (ROM) cost estimate was prepared for the design, construction, testing, and data analysis for an experimental series of large-scale (Liquefied Natural Gas) LNG spills on land and water that would result in the largest pool fires and vapor dispersion events ever conducted. Due to the expected cost of this large, multi-year program, the authors utilized Sandia's structured cost estimating methodology. This methodology insures that the efforts identified can be performed for the cost proposed at a plus or minus 30 percent confidence. The scale of the LNG spill, fire, and vapor dispersion tests proposed by GDF could produce hazard distances and testing safety issues that need to be fully explored. Based on our evaluations, Sandia can utilize much of our existing fire testing infrastructure for the large fire tests and some small dispersion tests (with some modifications) in Albuquerque, but we propose to develop a new dispersion testing site at our remote test area in Nevada because of the large hazard distances. While this might impact some testing logistics, the safety aspects warrant this approach. In addition, we have included a proposal to study cryogenic liquid spills on water and subsequent vaporization in the presence of waves. Sandia is working with DOE on applications that provide infrastructure pertinent to wave production. We present an approach to conduct repeatable wave/spill interaction testing that could utilize such infrastructure.

    The Gulf of Suez is considered as one of the most important petroleum provinces in Egypt and contains the Saqqara and Edfu oil fields located in the South Central portion of the Gulf of Suez. The Nubian sandstone reservoir in the Gulf of Suez basin is well known for its great capability to store and produce large volumes of hydrocarbons. The Nubian sandstone overlies basement rocks throughout most of the Gulf of Suez region. It consists of a sequence of sandstones and shales of Paleozoic to Cretaceous age. The Nubian sandstone intersected in most wells has excellent reservoir characteristics. Its porosity is controlled by sedimentation style and diagenesis. The cementation materials are mainly kaolinite and quartz overgrowths. The permeability of the Nubian sandstone is mainly controlled by grain size, sorting, porosity and clay content especially kaolinite and decreases with increase of kaolinite. The permeability of the Nubian Sandstone is evaluated using the Nuclear Magnetic Resonance (NMR technology) and formation pressure data in addition to the conventional logs and the results were calibrated using core data. In this work, the Nubian sandstone was investigated and evaluated using complete suites of conventional and advanced logging techniques to understand its reservoir characteristics which have impact on economics of oil recovery. The Nubian reservoir has a complicated wettability nature which affects the petrophysical evaluation and reservoir productivity. So, understanding the reservoir wettability is very important for managing well performance, productivity and oil recovery.

    Full Text Available This work deals with the evaluation of the structural set-up of the southern part of Sinai Peninsula, Gulf of Suez and western part of Gulf of Suez from magnetic, gravity, and seismic data. The utilised techniques including the Least Squares separation method suggest NW, NE, and E-W trends. The trend analysis shows north 35°-45° west, north 15°-25° east and E-W which may be related to the Gulf of Suez and Red Sea stresses.The Euler deconvolution illustrates that the area is highly affected by these trends. Depths range from 1 km to more than 3 km below sea level and its magnetic susceptibility ranges between 1 to 3 SI units. The 2.5D magnetic modelling and analytical signal techniques confirm the depths to the magnetic sources deduced by the Euler method, whereas the depth to the basement rocks ranges between 0 km to about 3 km indicating that it is subjected to strong tectonic activities. In addition, two seismic sections (EG-31 and MP-70, compiled by the Egyptian General Petroleum Cooperation (EGPC, were interpreted together with a geologic cross section. The studied area may be divided into several major blocks along the Gulf of Suez area. It can be concluded that the sedimentary was affected by basement tectonics as revealed by the two seismic sections.

  13. Gulfs of Suez and Aqaba: New insights from recent satellite-marine potential field data

    Science.gov (United States)

    Almalki, Khalid A.; Mahmud, Syed A.

    2018-01-01

    Previous models and interpretations of crustal geometry and the nature of the crust under the Gulfs of Suez and Aqaba have generally been based on a local or small scale and have been limited due to a lack of data. The few studies that present larger scale crustal and uppermost mantle structure were dependent on one type of data with no consideration of other geological and/or geophysical features. Satellite-marine potential field data provide for the first time a full coverage dataset of the Gulfs of Suez and Aqaba as well as the Sinai area at the same scale which allows for a better understanding of crustal domains and geometry and the interplay between tectonic events. To that end, our forward models of magnetic and gravity data constrained by seismic data and available geological information in this area suggest that the crustal domains in the Gulf of Aqaba are more complicated than those in the Gulf of Suez. Our result supports continental rifting under most of the Gulf of Suez and a combination of transitional and continental crusts under the Gulf of Aqaba. Yet, there is no evidence of oceanic segment development in these gulfs. Regardless of oceanic or transitional crust, the models support a link between the Arabia and Sinai plates at the central Gulf of Aqaba. The data also support that Red Sea tectonism has no connection to or influence on both gulfs. The result suggests a continuation of lithological elements from land into the eastern part of the Gulf of Suez. Our synthesis and interpretations may play an important role in the reassessment of the tectonic history and extension of this important rift system.

    2013-03-01

    Full Text Available A lot of engraved limestone blocks were discovered at Awlad Abu Musa (east of Suez, Egypt in 1995/2007 by Supreme Council of Antiquities. The stone blocks were seriously affected by archaeological environments during burial environment in agriculture land. They were covered with thick clay layer with soil particles that disfigured them and hid their inscriptions. Prior to the conservation intervention, the materials were characterized by X-ray diffraction, optical microscopy, scanning electron microscopy with energy-dispersive X-ray spectroscopy, Chemical analyses of ground water and microbiological study. After the material characterization, the conservation and restoration of the stone blocks were carried out including cleaning, consolidation, reduction of salts, Re-jointing, restoration and completion of lost parts. After that the blocks were exhibited in Suez museum.

  6. Mobility and Fate of Pollutants in the Aquifer System of the Northwestern Suez Gulf, Egypt.

    The northwestern part of Suez Gulf region is a strategic area in Egypt. It includes important sources of national income. To achieve the development goals, the government has established huge projects in this area (e.g. establishment and expanding of a large commercial port at Ain Sokhna, many industrial zones as well as tourism projects). The utilization of the Suez Gulf resources and their continuing development mainly depend on the creation of actual pollution control programs. The environmental quality control and pollution reduction activities are important ingredients of any economic development program. These different activities in this area depend mainly on the groundwater that is pumped intensively from different water bearing formations or aquifers. The main objective of the present work is compiling the previous studies from the 1980s up to 2015. These studies are concerned with estimating the concentrations of different pollutants in various ecosystems in the northwestern Suez Gulf region. Also, to provide an explanation for the movement of different pollutants such as organic and heavy metals from contaminated land to ground and surface (Gulf) waters. This issue has not been extensively surveyed before, and this review, gives specific directions for future monitoring and remediation strategies in this region.

    Toni, Mostafa

    2017-06-01

    This article aims to simulate the ground motion parameters of the moderate magnitude (ML 5.1) June 1, 2013 Gulf of Suez earthquake, which represents the largest instrumental earthquake to be recorded in the middle part of the Gulf of Suez up to now. This event was felt in all cities located on both sides of the Gulf of Suez, with minor damage to property near the epicenter; however, no casualties were observed. The stochastic technique with the site-dependent spectral model is used to simulate the strong ground motion parameters of this earthquake in the cities located at the western side of the Gulf of Suez and north Red Sea namely: Suez, Ain Sokhna, Zafarana, Ras Gharib, and Hurghada. The presence of many tourist resorts and the increase in land use planning in the considered cities represent the motivation of the current study. The simulated parameters comprise the Peak Ground Acceleration (PGA), Peak Ground Velocity (PGV), and Peak Ground Displacement (PGD), in addition to Pseudo Spectral Acceleration (PSA). The model developed for ground motion simulation is validated by using the recordings of three accelerographs installed around the epicenter of the investigated earthquake. Depending on the site effect that has been determined in the investigated areas by using geotechnical data (e.g., shear wave velocities and microtremor recordings), the investigated areas are classified into two zones (A and B). Zone A is characterized by higher site amplification than Zone B. The ground motion parameters are simulated at each zone in the considered areas. The results reveal that the highest values of PGA, PGV, and PGD are observed at Ras Gharib city (epicentral distance ∼ 11 km) as 67 cm/s2, 2.53 cm/s, and 0.45 cm respectively for Zone A, and as 26.5 cm/s2, 1.0 cm/s, and 0.2 cm respectively for Zone B, while the lowest values of PGA, PGV, and PGD are observed at Suez city (epicentral distance ∼ 190 km) as 3.0 cm/s2, 0.2 cm/s, and 0.05 cm/s respectively for Zone A

    During the last few years, Egypt has emerged as the leader of wind power in the Middle East and Africa. In the Gulf of Suez region, a continuously expanding large-scale grid-connected wind farm is available at Zafarana site. The Gulf of EL-Zayt site in the Gulf of Suez region is now under extensive studies related to wind power projects such as feasibility and bird migration studies. Therefore, the Gulf of Suez region is considered in this paper for optimal site matching of wind turbine generator (WTG). This paper treats the problem of site matching of WTG through improved formulation of the capacity factor. Such factor is estimated based on Weibull PDF and an accurate model for the WTG output-power-curve. Ornithological, martial, and other limitations placed on WTG hub heights in the Gulf of Suez region in Egypt are taken into account. In addition, a MATLAB based program is created to implement the presented technique of optimal site matching of WTG. Based on turbine-performance-index (TPI) maximization, optimal output-power-curve and optimal commercial WTG are determined for each candidate site in the Gulf of Suez region. Long-term performance measurements at Zafarana wind farms in comparison with the results are used to validate the presented technique and the optimality of the results. (author)

    Full Text Available Israel and China have finalized a project plan initiated in 2012. This project received the green light from Israeli cabinet in March 2014. With this venture, China will build a cargo railway line connecting the port of Eilat in the Red Sea to the ports of Ashdod and Haifa on the Mediterranean coast in Israel. This project will be a shipping alternative to the Suez Canal. This statement is the corner stone of this paper and considered an hypothesis to be verified within this paper. The methodology used is based on the concept of “market position.” The main conclusion, theoretically, the Red-Med railway could be an alternative to the Suez Canal for in the 4,000 TFE Vessels containers transportation as far as costs are concerned. However, other concerns, such as the security in the Suez Canal and the risk of its shutdown, must be considered too.

    Full Text Available Introduction. Blood stream infection (BSI is a common problem of newborn in neonatal intensive care units (NICUs. Monitoring neonatal infections is increasingly regarded as an important contributor to safe and high-quality healthcare. It results in high mortality rate and serious complications. So, our aim was to determine the incidence and the pattern of BSIs in the NICU of Suez Canal University Hospital, Egypt, and to determine its impact on hospitalization, mortality, and morbidity. Methods. This study was a prospective one in which all neonates admitted to the NICUs in Suez Canal University hospital between January, 2013 and June 2013 were enrolled. Blood stream infections were monitored prospectively. The health care associated infection rate, mortality rate, causative organism, and risk factors were studied. Results. A total of 317 neonates were admitted to the NICU with a mortality rate of 36.0%. During this study period, 115/317 (36.3% developed clinical signs of sepsis and were confirmed as BSIs by blood culture in only 90 neonates with 97 isolates. The total mean length of stay was significantly longer among infected than noninfected neonates (34.5 ± 18.3 and 10.8 ± 9.9 days, resp., P value < 0.001. The overall mortality rates among infected and noninfected neonates were 38.9% and 34.8%, respectively, with a significant difference. Klebsiella spp. were the most common pathogen (27.8% followed by Pseudomonas (21.6% and Staphylococcus aureus (15.4%. Conclusion. The rate of BSIs in NICU at Suez Canal University Hospital was relatively high with high mortality rate (36.0%.

    Water samples were seasonally collected from 12 stations of the eastern coast of Suez Gulf during autumn of 2012 and winter, spring, and summer of 2013 in order to investigate phytoplankton community structure in relation to some physicochemical parameters. The study area harbored a diversified phytoplankton community (138 species), belonging to 67 genera. Four algal groups were represented and classified as Bacillariophyceae (90 species), Dinophyceae (28 species), Cyanophyceae (16 species), and Chlorophyceae (4 species). The results indicated a relative high occurrence of some species namely.; Pleurotaenium trabecula of green algae; Chaetoceros lorenzianus, Proboscia alata var. gracillima, Pseudosolenia calcar-avis, and Pseudo-nitzschia pungens of diatoms; Trichodesmium erythraeum and Pseudoanabaena limnetica of cyanophytes. Most of other algal species were fairly distributed at the selected stations of the study area. The total abundance of phytoplankton was relatively low (average of 2989 unit/L) in the eastern coast of Suez Gulf, as compared its western coast and the northern part of the Red Sea. The diversity of phytoplankton species was relatively high (2.35-3.82 nats) with an annual average of 3.22 nats in the present study. The results concluded that most of eastern coast of Suez Gulf is still healthy, relatively unpolluted, and oligotrophic area, which is clearly achieved by the low values of dissolved phosphate (0.025-0.3 μM), nitrate (0.18-1.26 μM), and dissolved ammonium (0.81-5.36 μM). Even if the occurrence of potentially harmful algae species was low, the study area should be monitored continuously. The dissolved oxygen ranged between 1.77 and 8.41 mg/L and pH values between 7.6 and 8.41. The multiple regression analysis showed that the dissolved nitrate and pH values were the most effective factors that controlled the seasonal fluctuations of phytoplankton along the eastern coast of Suez Gulf during 2012-2013.

  3. Revenge versus rapport: Interrogation, terrorism, and torture.

    2017-04-01

    This review begins with the historical context of harsh interrogation methods that have been used repeatedly since the Second World War. This is despite the legal, ethical and moral sanctions against them and the lack of evidence for their efficacy. Revenge-motivated interrogations (Carlsmith & Sood, 2009) regularly occur in high conflict, high uncertainty situations and where there is dehumanization of the enemy. These methods are diametrically opposed to the humanization process required for adopting rapport-based methods-for which there is an increasing corpus of studies evidencing their efficacy. We review this emerging field of study and show how rapport-based methods rely on building alliances and involve a specific set of interpersonal skills on the part of the interrogator. We conclude with 2 key propositions: (a) for psychologists to firmly maintain the Hippocratic Oath of "first do no harm," irrespective of perceived threat and uncertainty, and (b) for wider recognition of the empirical evidence that rapport-based approaches work and revenge tactics do not. Proposition (a) is directly in line with fundamental ethical principles of practice for anyone in a caring profession. Proposition (b) is based on the requirement for psychology to protect and promote human welfare and to base conclusions on objective evidence.

    Full Text Available Freight is a key variable of the economy, has a crucial role in the spatial relationships between different and distant markets and, to that extent, represents the physical medium by which exchanges of goods are realized, constituting the backbone of world trade. Throughout history, man has always sought methods by which speed up and simplify the connections between the many points of the globe both through the use of increasingly efficient technologies, and through the construction of new ways of access frequently changing physical morphology of territories. This process is still evolving, and in fact in 2015 there has been a new change that has affected one of the major hubs of the world: the Suez Canal. The Canal doubling is a strong signal of change as not only induces to reflect on current developments within the mode of transport, in particular the increasing race to the naval gigantism, but it also implies a newfound centrality of the Mediterranean Sea which, thanks to the new infrastructure, will increase its transit flows. This involves, on the one hand, an increase in business opportunities, and on the other, the formation of new hierarchies between the port systems of the countries that surround it. The underlying theme of the essay revolves around the recent trend of the modern shipping, and on variables that influenced the decision to double the channel. It will analyze the “New Suez Canal“ and its real capacity to attract more transit flows both in quantitative terms and in relation to the types of ships that can cross it and in relation to the origin of these flows. Finally the focus will be on port and logistics systems of the Mediterranean countries in order to understand which of them is more ready to seize any new opportunities involved.

    Depositional environment and maturation assessments of source rocks from the central Gulf of Suez, Egypt were evaluated utilizing the biomarker distributions in nine crude oils derived from a syn-rift tectonic sequence of the central Gulf of Suez province. No obvious variations were observed amongst the studied crude oils, suggesting that these oils are all of the same genetic type. These oils feature a predominance of oleanane, reaching 24%, and a relatively low gammacerane concentration of 10%, suggesting that these oils were derived from a terrigenous organofacies source rock with a significant angiosperm higher land plants input deposited within the marginally mature syn-rift shale of Lower Miocene Nukhul, Rudeis and Kareem formations of mixed kerogen types II-III. Maturity parameters based on various sterane isomerisation distributions, i.e. C{sub 29}{alpha}{beta}{beta}/({alpha}{beta}{beta}+{alpha}{alpha}{alpha}). C{sub 29}{alpha}{alpha}{alpha}20S/(S+R) and TAS/(TAS+MAS) and aromatic sulfur compounds such as 4-MDBT/ 1-MDBT, 4,6/-1,4-DMBT, 2,4/-1,4-DMDBT and the DBT/phenanthrene indicate a low thermal maturation level for the generated hydrocarbons within the syn-rift lithostratigraphic succession. These similarities in geologic occurrences and biomarker characteristics suggest the possibility that the hydrocarbon expulsion could have been initiated from deeply buried Miocene source rocks and trapped within the syn-rift structures throughout the extensional faults of the central Gulf of Suez province.

  11. La conflictualité des rapports de travail dans l’économie de la connaissance: une perspective identitaire

    Directory of Open Access Journals (Sweden)

    William Rojas-Rojas

    2009-06-01

    Full Text Available Cet article a pour objectif de mettre en avant l’irréductibilité du conflit dans les rapports de travail entre dirigeants et subordonnés au sein des entreprises les plus avancées des économies développées. La conflictualité dans les rapports de travail est envisagée dans une perspective identitaire s’appuyant sur le concept psychanalytique d’inhumanité. L’inhumanité au travail est définie comme la dimension de la condition humaine qui conduit l’individu à affirmer son identité par la négation partielle de la condition d’humanité d’autrui dans les rapports de travail. Les auteurs entendent ainsi montrer l’illusion managériale qui préside à la mise en place de programmes visant à a-conflictualiser les rapports de travail dans l’organisation. Pour les auteurs, ces programmes ne peuvent faire disparaître une inhumanité profondément ancrée dans les structures formelles et dans le système culturel, symbolique et imaginaire de l’organisation. La permanence de l’inhumanité dans les rapports de travail reflète l’existence de puissants obstacles psychiques et culturels s’opposant à la reconnaissance pleine et entière de la condition humaine au sein des organisations. L’impossibilité d’exprimer l’altérité dans son identité dans le champ organisationnel conduit à déplacer la pulsion agressive vers la violence non plus symbolique mais concrète. Et face à la violence, le management n’a ni emprise, ni outil de gestion. Comme le démontre l’histoire de l’humanité, seule la civilisation et la culture peuvent aboutir à mieux reconnaître et se reconnaître dans l’altérité.

    2015-04-01

    Faculty of Medicine, Suez Canal University (FOM/SCU) was established as community oriented school with innovative educational strategies. Social accountability represents the commitment of the medical school towards the community it serves. To assess FOM/SCU compliance to social accountability using the "Conceptualization, Production, Usability" (CPU) model. FOM/SCU's practice was reviewed against CPU model parameters. CPU consists of three domains, 11 sections and 31 parameters. Data were collected through unstructured interviews with the main stakeholders and documents review since 2005 to 2013. FOM/SCU shows general compliance to the three domains of the CPU. Very good compliance was shown to the "P" domain of the model through FOM/SCU's innovative educational system, students and faculty members. More work is needed on the "C" and "U" domains. FOM/SCU complies with many parameters of the CPU model; however, more work should be accomplished to comply with some items in the C and U domains so that FOM/SCU can be recognized as a proactive socially accountable school.

    Full Text Available Vertical Electrical Soundings (VES and shallow seismic refraction data interpretation have been used to delineate groundwater aquifer and fault elements which are dissecting the northwestern part of Gulf of Suez. Thirty-five Vertical Electrical Soundings (VES were carried out and inverted through 3-D VES inversion to determine the subsurface stratigraphy, structures and groundwater aquifer potentialities. The results of VES inversion indicate that the study area consists of four geoelectrical units interpreted as surficial dry sand and gravels deposits, underlain by fresh water bearing zone, salt water bearing unit and limestone layer, at the bottom. The 3-D VES inversion indicates that the area is dissected by normal fault of NE-SW direction. Thirty-four shallow seismic refraction profiles of 94 m spread length have been used to delineate the geotechnical characteristics of surface layers, subsurface structures and subsurface lithology. The results of shallow seismic refraction indicate that the shallow part of the subsurface section consists of three layers, the first soil layer (dry gravels and sands of the recent deposits underlain by the second soil layer (sands and gravels of the Pleistocene while the third layer is the bedrock layer of sandstone and shale belonging to the Middle Miocene.

    Ireland, Connie; Berg, Bruce

    2008-08-01

    Although the number of females in law enforcement has increased in recent years, research suggests that the uniquely gendered contributions of females are minimized in favor of traditional modes of law enforcement, emphasizing physical presence, authoritative commands, and demonstrative control. This research examines women in parole, using in-depth interviews with a small convenience sample of female parole agents in California. Participants discussed their experiences as parole agents from the perspective of women in a predominantly male occupation. Overwhelmingly, they emphasized traditionally associated female traits of intuition, verbal communication, and relationships, over physical tactics. Participants emphasized the importance of building respect and rapport with parolees in multiple contexts, including in the parolees' homes, with the families of parolees, and at parolees' places of employment. Participants suggested that this approach ensures their personal safety and enhances parolee compliance, especially when considering their subjective account of experiences by male parole agents.

  20. Méthodes de soin actives et préventives. Apports des maîtres rituels javanais et rapport au développement Active and Prophylactic Cares. A Case Study of Javanese Masters’ Techniques and the Link to Development

    Directory of Open Access Journals (Sweden)

    Jean-Marc de Grave

    2012-11-01

    Full Text Available D’après un cas d’étude javanais, l’auteur propose une réflexion sur le caractère actif ou passif du rapport à la santé avec les conséquences sociales que cela revêt. Dans un premier temps, l’article présente une classification des soignants et l’arrière-plan socioculturel des pratiques de soin javanaises ; il présente aussi les conceptions javanaises de la maladie, finalement peu prises en compte dans les travaux préalables et se trouvant parfois en bute aux systèmes de valeurs de certaines tendances de l’islam. Ceci sert d’introduction à une ethnographie de première main sur des maîtres rituels et des maîtres d’arts martiaux javanais, les techniques thérapeutiques qu’ils utilisent et qu’ils enseignent – liées à l’initiation rituelle, aux cultes locaux, à la méditation, aux exercices du souffle, à la phytothérapie –, ainsi que le public auquel ils s’adressent. Les différents exemples décrits indiquent clairement qu’une tendance sélective des techniques se met en place depuis une vingtaine d’années, tendance qui s’accompagne dans certains cas d’une sécularisation et d’une standardisation ; cette modification permet à un public élargi de pratiquer les soins de façon active pour soi-même et pour les proches. Une tendance plus récente des praticiens consiste à afficher des tarifs pour se faire payer en monnaie moderne, ce qui a pour effet d’induire un nouveau type de passivité en matière de santé. La question est alors posée de savoir si la standardisation des techniques de « tradi-praticiens » telle qu’elle est induite par l’action de l’Organisation mondiale de la santé ne risque pas finalement de renforcer le caractère passif des patients à l’égard de pratiques qui fonctionnaient pour beaucoup sur un principe actif.Drawing from a Javanese case study, the article proposes a reflection on the active or passive character developed towards one’s health

    Full Text Available Positive relationships between instructors and students are critical to effective learning in the classroom. Rooted in the Scholarship of Teaching and Learning (SoTL, and centered at the crossroads of interpersonal communication and instructional communication (Affective Learning Model, this study examines how instructors in a Taiwan ESL school build relationships with Taiwanese students. Instructors were interviewed regarding the behaviors they use to build rapport with their students. Results show that instructors build rapport with their students using several specific techniques: uncommonly attentive behaviors, common grounding behaviors, courteous behaviors, connecting behavior, information sharing behavior, a balancing of connection and authority, adaptation of rapport to student level, and provision of a respite to norms. The findings provide specific examples of how instructors can build rapport in intercultural classrooms.

    The negative effect of distance on bilateral trade is one of the most robust findings in international trade. However, the underlying causes of this negative relationship are less well understood. This paper exploits a temporary shock to distance, the closing of the Suez canal in 1967 and its reopening in 1975, to examine the effect of distance on trade and the effect of trade on income. Time series variation in sea distance allows for the inclusion of pair effects which account for static di...

    Full Text Available There are currently 22 public and 2 private medical schools in Egypt, which graduate around 10,000 physicians annually. While Kasr Al-Eini (Cairo University is the oldest one; established in 1827, the Suez Canal Faculty of Medicine (FOM/SCU is the first to adopt an integrated, student centered, problem- and community-based curriculum since its inauguration in 1978. Apart from Port Said medical school, which was established in 2013, the remaining medical schools either generally adopt the conventional teacher-centered and subject-based curricula or starting to introduce changes in their curricula in order to fulfill the National Academic Reference Standards (NARS, published in 2008 by the National Authority of Quality Assurance and Accreditation in Education (NAQAAE. This authority was established in 2006 as part of the reform agenda of the education system in Egypt. All institutes are mandated to comply with the set national standards and apply to NAQAAE for national accreditation. FOM/SCU was the first higher education institute in Egypt to obtain national accreditation in 15 May 2010 and also the first to be re-accredited in August 2015. The principal reason for this achievement is the implementation of innovative strategies by FOM/SCU that perfectly match the NARS, which were issued 30 years after the inception of FOM/SCU. Many traditional schools are now trying to implement some of these strategies, and these trials are applied either as separate parallel innovative programs (Mansoura, Ain Shams, and Menoufia, integrated modules (Zagazig, Armed Forces College of Medicine, or new curriculum (Alexandria. FOM/SCU, through its WHO collaborating center in the field of medical education and its department of medical education, offers help to all schools in Egypt in this regard. In parallel, FOM/SCU members have also offered training and consultations to numerous medical schools in other countries, including Syria, Libya, Yemen, Sudan, Somalia, and

    2017-04-01

    Many studies based on GPS data, have been carried out to shed light on the current kinematics of the Suez-Sinai area, where the interaction of the African and Arabian plates is active. A combined GPS velocity solution covering a wide area from Egypt to Middle East allowed us to infer the current rates across the plate margins. We have estimated 126 velocities from time series of 90 permanent and 36 non permanent GPS sites located in Africa (Egypt), Eurasia and Arabia plates in the time span 1996-2015, the largest available for the Egyptian sites. We have combined our velocity solution in a least-squares sense with two other recent velocity solutions of networks located around the eastern Mediterranean, obtaining a final IGb08 velocity field of about 450 sites. Then, we have estimated the IGb08 Euler poles of Africa, Sinai and Arabia, analyzing the kinematics of the Sinai area, particular velocity profiles, and estimating the 2D strain rate field. We show that it is possible to reliably model the rigid motion of Sinai block only including some GPS sites located south of the Carmel Fault. The estimated relative motion with respect to Africa is of the order of 2-3 mm/yr, however there is a clear mismatch between the modeled and the observed velocities in the southern Sinai sites. We have also assessed the NNE left shear motion along the Dead Sea Transform Fault, estimating a relative motion between Arabia and Africa of about 6 mm/yr in the direction of the Red Sea opening.

  7. Using sequence stratigraphic approaches in a highly tectonic area: Case study - Nubia (A) sandstone in southwestern Gulf of Suez, Egypt

    2017-12-01

    West Esh El Mallaha area is located west of the Hurghada shoreline. It pertains to the southwestern province of the Gulf of Suez. Nubia (A) sandstone is one of the prolific reservoirs in the western side along the Gulf of Suez area. To enhance further oil production and to develop this reservoir, it is important to gain a clear understanding of the reservoir in terms of its depositional origin. In west Esh El Mallaha area, the understanding of the depositional setting of Nubia (A) is relatively hard due to the limited number of cores. A comprehensive workflow which integrates all geological datasets (electrical logs pattern, the high resolution biostratigraphic analysis, and previous studies) which has been performed for the Nubia (A), enables to recognize different patterns of electrical logs, which are used to define the sequence stratigraphy and systems tracts for Nubia (A). The Lower Nubia (A) is characterized by fining-upward profile and well-developed coarsening-straight profile interpreted as a braided - fluvial facies (lowstand system tract). On the other hand, the upper Nubia (A) is characterized by fining-upward, coarsening-upward, and bell profile interpreted as meandering fluvial to fluvio-dominated delta (transgressive system tract). This study is an approach to build a reliable geological model, and give wide view to evaluate and develop the reservoir in the drilled areas and predict sand distribution in the undrilled areas despite the limited number of cores.

    Soil and groundwater contamination is one of the important environmental problems at petroleum-related sites, which causes critical environmental and health defects. Severe petroleum hydrocarbon contamination from coastal refinery plant was detected in a shallow Quaternary sandy aquifer is bordered by Gulf in the Northwestern Gulf of Suez, Egypt. The overall objective of this investigation is to estimate the organic hydrocarbons in shallow sandy aquifers, released from continuous major point-source of pollution over a long period of time (91 years ago). This oil refinery contamination resulted mainly in the improper disposal of hydrocarbons and produced water releases caused by equipment failures, vandalism, and accidents that caused direct groundwater pollution or discharge into the gulf. In order to determine the fate of hydrocarbons, detailed field investigations were made to provide intensive deep profile information. Eight composite randomly sediment samples from a test plot were selected for demonstration. The tested plot was 50 m long × 50 m wide × 70 cm deep. Sediment samples were collected using an American auger around the point 29° 57' 33″ N and 32° 30' 40″ E in 2012 and covered an area of 2,500 m(2) which represents nearly 1/15 of total plant area (the total area of the plant is approximately 3.250 km(2)). The detected total petroleum hydrocarbons (TPHs) were 2.44, 2.62, 4.54, 4.78, 2.83, 3.22, 2.56, and 3.13 wt%, respectively. TPH was calculated by differences in weight and subjected to gas chromatography (GC). Hydrocarbons were analyzed on Hewlett-Packard (HP-7890 plus) gas chromatograph equipped with a flame ionization detector (FID). The percentage of paraffine of the investigated TPH samples was 7.33, 7.24, 7.58, 8.25, 10.25, 9.89, 14.77, and 17.53 wt%, respectively.

    Full Text Available Vibriosis is a globally threatening bacterial disease affecting mariculture with high mortalities and severe economic losses. Isolation and Identification of different vibrio species were performed to a total number of one hundred moribund and freshly dead Solea aegyptiaca, Epinephelus marginatus and Mugil cephalus collected from Lake Qarun and Gulf of Suez. Phenotypic picture and molecular identification based on use of 16SrRNA gene sequence confirmed 44 strains as vibrio species. Further molecular identification of retrieved vibrio spp. using species specific primers for collagenase, ToxR and Vvh genes categorized 10 isolates belong to V. alginolyticus, 8 isolates belong to V. parahaemolyticus and 6 isolates belong to V. vulnificus. The total prevalence of vibriosis was 44% where the highest prevalence was recorded in Lake Qarun examined fishes.

    2010-01-01

    Full Text Available A introdução do sintagma "psicose ordinária" por J.-A. Miller permitiu enfatizar a atualidade de uma nova clínica dita "continuista", não relegando mais a psicose somente às formas fixadas pelo discurso psiquiátrico. No tempo em que o Outro não existe, o atendimento desses sujeitos permite levar em conta as modalidades de bricolagem que fazem com que as dimensões RSI se mantenham juntas. Este artigo pretende iniciar uma reflexão em torno das ligações entre função paterna e relação ao saber. Para tanto, parte da distinção entre neurose e psicose a partir da relação do sujeito com o saber e discute o encontro do sujeito com um analista e o comparecimento de um saber já constituído, um saber total, de onde o psicótico retira sua certeza. Ao mesmo tempo, distingue na psicose o processo de pensamento e a relação com o corpo. A partir de dois casos clínicos, aborda a vergonha e a descrença e enfatiza as semelhanças e diferenças entre neurose e "psicose ordinária" na relação com o saber. Conclui com considerações sobre a posição do analista, de destinatário de signos sem sentido, com vistas a auxiliar uma abertura ao laço social para o sujeito da psicose.

    Full Text Available The introduction of the syntagm "ordinary psychosis" by J-A miller has enabled to underline the current relevance of a new clinic called "continuist", no more accepting psychosis in the forms fixed by the psychiatric discourse. In times when the Other does not exist, the treatment of these subjects allows to unveil the types of bricolage, making it possible to enlace the categories RSI. This article seeks to initiate a reflection about the links between paternal function and relation to knowledge. In order to do this, starts from the distinction between neurosis and psychosis based on the subject's relation to knowledge and discusses the subject's encounter with an analyst, as well as the presence of an already constituted knowledge, a total knowledge, from which the psychotic derives his certainty. At the same time, distinguishes the process of thought and the relation to the body in psychosis. From two clinical cases, approaches the shame and the disbelief, and emphasizes the similarities and differences between neurosis and "ordinary psychosis" in the relation to knowledge. The article concludes with considerations about the analyst's position of addressee of signs without sense, which intends to assist an opening to the social lace for the psychosis' subject.

    In order to understand the structure and biological significance of integrons and associated gene cassettes in marine polluted sediments, metagenomic DNAs were extracted from sites at Suez and Tokyo Bays. PCR amplicons containing new integrase genes, intI, linked with novel gene cassettes, were recovered and had sizes from 1.8 to 2.5 kb. This approach uncovered, for the first time, the structure and diversity of both marine integron attachment site, attI, and the first gene cassette, the most efficiently expressed integron-associated gene cassette. The recovered 13 and 20 intI phylotypes, from Suez and Tokyo Bay samples, respectively, showed a highly divergence, suggesting a difference in integron composition between the sampling sites. Some intI phylotypes showed similarity with that from Geobacter metallireducens, belonging to Deltaproteobacteria, the dominant class in both sampling sites, as determined by 16S rRNA gene analysis. Thirty distinct families of putative attI site, as determined by the presence of an attI-like simple site, were recovered. A total of 146 and 68 gene cassettes represented Suez and Tokyo Bay unsaturated cassette pools, respectively. Gene cassettes, including a first cassette, from both sampling sites encoded two novel families of glyoxalase/bleomycin antibiotic-resistance protein. Gene cassettes from Suez Bay encoded proteins similar to haloacid dehalogenases, protein disulfide isomerases and death-on-curing and plasmid maintenance system killer proteins. First gene cassettes from Tokyo Bay encoded a xenobiotic-degrading protein, cardiolipin synthetase, esterase and WD40-like β propeller protein. Many of the first gene cassettes encoded proteins with no ascribable function but some of them were duplicated and possessed signal functional sites, suggesting efficient adaptive functions to their bacterial sources. Thus, each sampling site had a specific profile of integrons and cassette types consistent with the hypothesis that the

    Impact of chemical pollution on expression of stress protein genes in the bass Epinephelus guaga collected from several locations including Suez Oil Production Port (Floating port), Atakah Fishing Port, Adabiya Port and Tawfik Port in Suez Governorate, Egypt, was investigated. In the current study, levels of polycyclic aromatic hydrocarbons (PAHs) in water and fish samples collected from Suez Gulf were assessed. In addition, gills and liver tissues of caught bass fish were used to address the interaction between pollution status and the expression of stress-related genes (Hsp70a, Hsp70b, Hsp47, MT and CYP1A). Our analysis demonstrated that levels of PAHs in Floating and Tawfik ports were higher than those found in the Atakah Fishing Port and the Adabiya Port. In addition, MDA and PC contents were significantly higher in gills and liver tissues collected from Floating and Tawfik ports than those collected from Adabiya and Atakah ports. In correlation to the above results, all fish collected from the Floating and Tawfik ports presented a significant increase in Hsp-, MT- and CYP1A-mRNAs. On the other hand, fish samples collected from the Atakah Fishing and Adabiya ports showed no induction of the stress-related genes transcription in such tissues. In conclusion, the current research demonstrates that remarkable increase in PAH contaminants levels in Floating and Tawfik ports are correlated with the levels stress protein-related genes transcription in E. guaga gills and liver tissues.

  10. Reservoir zonation based on statistical analyses: A case study of the Nubian sandstone, Gulf of Suez, Egypt

    Science.gov (United States)

    El Sharawy, Mohamed S.; Gaafar, Gamal R.

    2016-12-01

    Both reservoir engineers and petrophysicists have been concerned about dividing a reservoir into zones for engineering and petrophysics purposes. Through decades, several techniques and approaches were introduced. Out of them, statistical reservoir zonation, stratigraphic modified Lorenz (SML) plot and the principal component and clustering analyses techniques were chosen to apply on the Nubian sandstone reservoir of Palaeozoic - Lower Cretaceous age, Gulf of Suez, Egypt, by using five adjacent wells. The studied reservoir consists mainly of sandstone with some intercalation of shale layers with varying thickness from one well to another. The permeability ranged from less than 1 md to more than 1000 md. The statistical reservoir zonation technique, depending on core permeability, indicated that the cored interval of the studied reservoir can be divided into two zones. Using reservoir properties such as porosity, bulk density, acoustic impedance and interval transit time indicated also two zones with an obvious variation in separation depth and zones continuity. The stratigraphic modified Lorenz (SML) plot indicated the presence of more than 9 flow units in the cored interval as well as a high degree of microscopic heterogeneity. On the other hand, principal component and cluster analyses, depending on well logging data (gamma ray, sonic, density and neutron), indicated that the whole reservoir can be divided at least into four electrofacies having a noticeable variation in reservoir quality, as correlated with the measured permeability. Furthermore, continuity or discontinuity of the reservoir zones can be determined using this analysis.

    The Gulf of Suez region represents the most promising area in Egypt for geothermal exploration which is characterized by superficial thermal manifestations represented by a cluster of hot springs with varying temperatures from 35 to 72 °C. The main purpose of the present study was to shed the light on the integration between gravity work and geothermal data in detecting the main subsurface structures in addition to expecting the geothermal sources in the area under consideration. Correction was applied on the bottom hole temperature data to obtain the true formation equilibrium temperatures that can provide useful information about the subsurface thermal regime. Based on these logging data, temperature gradient and heat flow values were computed at each well, and it is found that the mean geothermal gradient of the study area is 32 °C/km; nevertheless, some local geothermal potential fields were located with more than 40 °C/km. Also, heat flow values are ranging from 45 to 115 mW/m2. The Bouguer anomaly map of the study area was used for delineating the subsurface structures and tectonic trends that have resulted in a potential heat source. The gravity inversion revealed a good correlation between areas of high temperature gradients, high heat flow and positive gravity anomalies. The high temperature gradient and heat flow values suggested being associated with a noticeable hydrothermal source of heat anomaly located at relatively shallow depths which is expected to be due to the uplift of the basement in the area.

    The energy sector is in fever. In less than a week (February 21 to 26, 2006), the Europe of energy has fallen into a frenzy of mergers and acquisitions: the German E.ON offered 29.1 billion euros to get the Spanish Endesa, Electricite de France (EdF), who already got the Italian Edison in 2005, is ready for more major acquisitions, the Italian Enel is candidate for the repurchasing of Suez, while Gaz de France (GdF) and Suez have started a surprise merger. The stake of this match between giants is their growing up and the penetration of foreign markets before their complete liberalization in July 2007. The potential victims of these actions are the competition and the clients, the industrial ones first. (J.S.)

  18. Present-day stress fields of the Gulf of Suez (Egypt) based on exploratory well data: Non-uniform regional extension and its relation to inherited structures and local plate motion

    Science.gov (United States)

    Bosworth, William; Durocher, Scott

    2017-12-01

    The Gulf of Suez is the prototype model of a failed or aborted continental rift. However, the basin is seismically active and the footwalls of several major extensional faults continue to rise at the present time. Furthermore, decadal-length Global Positioning System (GPS) datasets demonstrate that the Sinai micro-plate continues to separate from Africa in a northerly direction at ∼0.15 cm/yr with a Gulf of Suez rift-normal component of ∼0.05 cm/yr. Geologic and GPS observations both indicate that the rift is now undergoing highly-oblique extension. Previous interpretations of borehole breakouts in industry exploration wells suggested that the minimum horizontal stress (Shmin) in the southern Gulf of Suez is presently aligned ∼015°. New subsurface data from the accommodation zone boundary between the Central and Darag (northern) sub-basins similarly identifies an extension direction of approximately N-S. By contrast, in the Central sub-basin itself breakout and drilling-induced fracture (DIF) data indicate NE-SW extension, or rift-normal movement that is similar to the documented older Miocene history of the entire basin. Based on these observations the present-day stress field of the Gulf of Suez is spatially non-uniform. Variations are also present in local and teleseismic datasets. The northern Gulf of Suez shows relatively less seismicity, with very few events greater than M = 3. The central sub-basin is very active, with 17 events M ≥ 3 during the past 45 years, and these suggest NE-SW extension similar to the breakout data. The southern Gulf of Suez is the most seismically active and merges with an area of significant seismicity in the northern Red Sea. In the southern Gulf of Suez the seismicity is complex but focal plane analyses of the two largest historical events indicated NNE-SSW extension, in agreement with the breakout data. Differing interpretations have been proposed for the smaller magnitude seismicity. We suggest that each of the three

    This analysis re-instates the importance of the 1958 British intervention in Jordan within the study of Anglo-American relations and the revisionist literature on Suez. It does so by challenging the idea of British subservience to American foreign policy after the 1956 crisis, and it reveals two key lessons learnt by London: that Britain’s economy, power, and influence were in decline and that Britain could no longer intervene in the Middle East without American support. Having learnt these l...

  2. Oil pollution in the Red Sea — Environmental monitoring of an oilfield in a coral area, Gulf of Suez

    Science.gov (United States)

    Dicks, Brian

    The Red Sea is rapidly developing as one of the world's largest offshore oil production areas. It also comprises a wide range of tropical marine habitats, many of which are internationally recognised for their conservation, scientific, economic or recreational value. Past oil production, refining and transport have resulted in chronic pollution of some areas, and environmental programmes to protect new areas of development from pollution damage are assuming increasing importance. At the initiative of an Egyptian oil company operating in the Gulf of Suez, an environmental protection and management scheme has been prepared for a new offshore oilfield and marine terminal at Ras Budran. This paper describes the form of the scheme and the results of its component environmental surveys. The development area comprises rich and diverse marine communities of fringing coral reefs, nearshore lagoons, seagrass beds, sandy beaches and fine sediments offshore. A baseline survey was designed following detailed discussion of the scope of the development with the company and a preliminary site visit, and the fieldwork was completed in October 1980. On the basis of the findings of the survey, a series of recommendations was made to the company, aimed at reducing environmental impacts during construction and operation to a minimum and acceptable level. These were subsequently implemented and the results of a post-construction survey in February 1983 are reported which show that environmental damage to the nearshore habitats during the construction phase had been relatively small and localised. Recently, the biological information obtained from the two surveys has also been incorporated into oil spill contingency plans.

    Les réseaux de distribution de fluides au travers du site du CERN datent dans certains cas, du début du laboratoire et sont toujours exploités à l'heure actuelle. Souvent, les conduites sont en mauvais état et nécessitent de nombreuses réparations, généralement ponctuelles et peu durables. Leur maintenance devient de plus en plus lourde à assumer. De plus, dans le cas du réseau d'eau chaude sanitaire, le nombre d'utilisateurs a diminué au fil des ans. La principale cause est le co t du raccordement au réseau qui est souvent difficile à défendre par rapport à une installation localisée. Ainsi, aujourd'hui certaines parties de réseaux sont devenues surdimensionnées par rapport au besoin. Cela engendre des pertes énergétiques disproportionnées, aggravées par l'état souvent vétuste de l'isolation thermique.

  8. Student – teacher rapport: a new conceptualization for the context of higher education

    Directory of Open Access Journals (Sweden)

    Ana Bardorfer

    2014-02-01

    Full Text Available Various definitions of rapport can be found between different disciplines and also within a certain discipline, including higher education. Effective teaching is a challenging task and requires a skilled teacher. In addition to managing a variety of didactic and pedagogical approaches, teacher should also be able to create a positive learning environment, including creating a good rapport with his/her students. Unfortunately, numerous imprecise definitions of student-teacher rapport in higher education, usually taken from dictionaries, are used by researchers in this field. We belive this is the reason why they don't provide possibilities for clear operationalization and development of a proper instrument for measuring the quality of student-teacher rapport. In this paper we proposed a new conceptualization of student-teacher rapport in higher education, built on the existing model of general rapport and on the basis of relevant findings from the field of higher education. We defined rapport as an interactive phenomena and placed the emphasis on the subjective experience / insider's perspective, although the quality of rapport can also be estimated through various verbal and non-verbal clues. This experiental aspect is expressed in feelings and thoughts of interactants. Since the teacher acts as a leader of the teaching/learning process he/she is responsable for creating good rapport with his/her students. In the proposed conceptualization we've used same structural components as L. Tickle-Degnen and Rosenthal (1990 used in their model of rapport and adapted them for the context of higher education. These are positivity, mutual attention and coordination. Looking at the existing concepts of student-teacher rapport in higher education through the prism of the aforementioned model, it can be seen that all elements relate either to positivity or mutual attention, while the component of coordination is almost completely absent. In our opinion, it is

    2013-10-01

    Full Text Available Little research has described determinants and consequences of patient–provider rapport among people who inject drugs (PWIDs. This mixed-method study (a qualitatively described facilitators, barriers, and consequences to rapport development between PWIDs and their health care providers and (b quantitatively tested the hypothesis that quality of rapport is associated with positive patterns of service use. Two exploratory focus groups with PWIDs and care providers were conducted. Subsequently, 89 PWIDs completed a survey interview; of those, eight completed a follow-up qualitative interview. Qualitative results indicated that rapport is influenced by drug-related behaviors, addiction severity, provider expertise, patient-centered care, and perceived discrimination and that rapport then influences patient compliance, timing of care, and criminal activity. Quantitative results indicated that rapport predicted PWID satisfaction with care as well as frequency and timing of emergency department presentations. Results suggest that PWID–provider rapport has several unique determinants and is associated with positive health care outcomes.

  10. (ReExamining the Feminist Interview: Rapport, Gender “Matching,” and Emotional Labour

    Directory of Open Access Journals (Sweden)

    Rachel Thwaites

    2017-11-01

    Full Text Available Rapport is usually considered key to any interview situation: building the right kind of rapport can be the difference between success and failure in obtaining the required data. In feminist research, rapport is intended to be of a particular kind: created through mutual sharing, minimal power hierarchies, and a feeling of genuine trust between interviewer and interviewee (Oakley, 1981. There is a tension here of which feminist researchers and scholars should remain critical, as the idea of good feminist rapport can clash with the necessity of “getting the data.” Building rapport can entail minimising strongly held viewpoints, working hard on one’s emotions to ensure they do not reveal true thoughts, or suggesting an attitude of trust and mutual understanding that may feel disingenuous. If rapport is often a performance by the researcher, then this can clash with the intended open and honest feminist approach. In some cases, then, building rapport may pose a challenge to genuinely following a feminist approach to the research interview. In this paper, I wish to explore this tension in more detail in the context of the one-off interview and to what extent it can be resolved.

  12. Spectrometre de masse a ionisation Penning selective: Elimination des corrections necessaires a la determination du rapport isotopique de l'hydrogene

    Science.gov (United States)

    Letarte, Sylvain

    Dans le but d'ameliorer la precision avec laquelle le rapport isotopique de l'hydrogene peut etre determine, un spectrometre de masse a ionisation Penning a ete construit pour provoquer l'ionisation selective de l'hydrogene moleculaire et de l'hydrure de deuterium a partir d'un melange gazeux. L'utilisation d'atomes dans des etats d'excitation metastable s'est averee une solution adequate pour reponde a cette attente. L'emploi de l'helium, a l'interieur d'une source d'atomes metastables construit specifiquement pour ce travail, ne permet pas d'obtenir un spectre de masse compose uniquement des deux molecules d'interet. L'ionisation de ces dernieres provient de deux processus distincts, soient l'ionisation Penning et l'ionisation par bombardement electronique. Contrairement a l'helium, il a ete demontre que le neon metastable est un candidat ideal pour produire l'ionisation selective de type Penning. Le nombre d'ions produits est directement proportionnel au courant de la decharge electrique et de la pression d'operation de la source d'atomes metastables. Ces resultats demontrent le potentiel d'un tel spectrometre de masse pour ameliorer la precision a laquelle le rapport isotopique peut etre determine comparativement aux autres techniques existantes.

  16. The Extravert Advantage: How and When Extraverts Build Rapport With Other People.

    Duffy, Korrina A; Chartrand, Tanya L

    2015-11-01

    Extraverts are better than introverts at building rapport, but it remains unknown what they do behaviorally to better connect with other individuals. We hypothesized that extraverts mimic more than introverts as a way to build rapport; however, we predicted that this social skillfulness of extraverts emerges only when they are motivated to affiliate. In Study 1, we found that extraversion predicted increased mimicry when an affiliation goal was present, but not when an affiliation goal was absent. In Study 2, we found that mimicry mediates the relationship between extraversion and rapport, but only when an affiliation goal is present. Our findings are the first to identify a behavior that extraverts engage in that helps them build rapport. Furthermore, our studies show that this skillfulness of extraverts emerges only when they are motivated to affiliate, providing evidence in favor of the reward-sensitivity-as-core model of extraversion over the sociability-as-core model of extraversion. © The Author(s) 2015.

    Full Text Available The present work aims to evaluate the organic geochemistry of the crude oils recovered from Ashrafi and GH oilfields within the Gulf of Suez to assess and investigate oil characterization, maturation, source depositional environments and oil families. The saturated hydrocarbons were determined by gas chromatography and gas chromatography/mass spectrometry. Pristane/phytane, isoprenoids/n-alkanes, CPI, homohopane, diasteranes, gammacerane index, C29 20S/20S+20R, C29/C30 hopane and Ts/Tm are determined. The results suggest that the studied crude oils belong to marine oil and are characterized by high level of maturation and sourced mainly from organic matters of marine origin with few terrestrial inputs.

    Full Text Available In the exploratory study reported here, we tested the efficacy of an intervention designed to train teenagers with Möbius Syndrome (MS to increase the use of alternative communication strategies (e.g. gestures to compensate for their lack of facial expressiveness. Specifically, we expected the intervention to increase the level of rapport experienced in social interactions by our participants. In addition, we aimed to identify the mechanisms responsible for any such increase in rapport. In the study, five teenagers with MS interacted with three naïve participants without MS before the intervention, and with three different naïve participants without MS after the intervention. Rapport was assessed by self-report and by behavioral coders who rated videos of the interactions. Individual nonverbal behavior was assessed via behavioral coders, while verbal behavior was automatically extracted from the sound files. Alignment was assessed using cross recurrence quantification analysis and mixed effects models. The results showed that observer-coded rapport was greater after the intervention, whereas self-reported rapport did not change significantly. Observer-coded gesture and expressivity increased in participants with and without MS, while overall linguistic alignment decreased. Fidgeting and repetitiveness of verbal behavior also decreased in both groups. In sum, the intervention may impact nonverbal and verbal behavior in participants with and without MS, increasing rapport as well as overall gesturing, while decreasing alignment.

  5. Assessment of genetic diversity and relationships among Egyptian mango (Mangifera indica L.) cultivers grown in Suez Canal and Sinai region using RAPD markers.

    Mansour, Hassan; Mekki, Laila E; Hussein, Mohammed A

    2014-01-01

    DNA-based RAPD (Random Amplification of Polymorphic DNA) markers have been used extensively to study genetic diversity and relationships in a number of fruit crops. In this study, 10 (7 commercial mango cultivars and 3 accessions) mango genotypes traditionally grown in Suez Canal and Sinai region of Egypt, were selected to assess genetic diversity and relatedness. Total genomic DNA was extracted and subjected to RAPD analysis using 30 arbitrary 10-mer primers. Of these, eleven primers were selected which gave 92 clear and bright fragments. A total of 72 polymorphic RAPD bands were detected out of 92 bands, generating 78% polymorphisms. The mean PIC values scores for all loci were of 0.85. This reflects a high level of discriminatory power of a marker and most of these primers produced unique band pattern for each cultivar. A dendrogram based on Nei's Genetic distance co-efficient implied a moderate degree of genetic diversity among the cultivars used for experimentation, with some differences. The hybrid which had derived from cultivar as female parent was placed together. In the cluster, the cultivars and accessions formed separate groups according to bearing habit and type of embryo and the members in each group were very closely linked. Cluster analysis clearly showed two main groups, the first consisting of indigenous to the Delta of Egypt cultivars and the second consisting of indigenous to the Suez Canal and Sinai region. From the analysis of results, it appears the majority of mango cultivars originated from a local mango genepool and were domesticated later. The results indicated the potential of RAPD markers for the identification and management of mango germplasm for breeding purposes.

  7. Considering Face, Rights, and Goals: A Critical Review of Rapport Management in Facilitator-Guided Simulation Debriefing Approaches.

    2018-02-01

    The rapport between facilitators and learners contributes to a conducive learning environment during simulation debriefing, but a theory to guide rapport management (RM) is lacking. The RM model is a potentially relevant conceptual framework because it describes three interrelated components of rapport-face, rights, and goals-which, when threatened, affect the rapport between interactants. This critical review explores how studies in the simulation debriefing literature describing postevent facilitator-guided debriefing approaches can be viewed through the lens of the RM model. All 34 identified studies alluded to at least one component of rapport, with less than half alluding to all three. There is preliminary evidence that the management of all three components of rapport during debriefing may contribute to improving short-term learning outcomes. Future studies could explore how the RM model can be used to guide debriefing approaches in various contexts and clarify why or how these approaches work.

    Introduction Le port de charge céphalique par les enfants est une méthode de manutention courante au Bénin. Peu d’étude sont investigué sur le port de charge céphalique chez les enfants. Méthodes Cette étude transversale vise à faire l’état des lieux et à identifier les facteurs associés au port de charge céphalique chez des enfants au Bénin. Au total,300 enfants âgés de 13,7 ± 2,6 ans ont participé à l’étude dans les 12 départements du Bénin. La méthode non probabiliste et la technique accidentelle ont été utilisées pour déterminer la taille de l’échantillon. La masse portée par les enfants constitue la variable dépendante. L’âge, la taille, les sites corporels des douleurs, l'ancienneté dans le port de charge etla fréquence hebdomadaire du port céphalique de charge constituent les variables indépendantes. Résultats Le rapport de la masse portée sur le poids corporel est évalué en moyenne à 66%. Pendant et après le port de charge, les douleurs ressenties sont localisées essentiellement au cou, au dos et au bas du dos. Le test de corrélation entre charge portée et la taille indique r = 0,58 (p < 0,001). Conclusion Cette étude indique que les enfants surchargent leur rachis lors du port de charge céphalique.

  14. Developing Rapport and Therapeutic Alliance During Telemental Health Sessions with Children and Adolescents.

    Goldstein, Felissa; Glueck, Dehra

    2016-04-01

    The purpose of this study was to describe the special considerations for building rapport and establishing a therapeutic alliance when conducting mental health evaluations for children and adolescents via videoconferencing. The authors review the literature and describe their experience in conducting mental health evaluations, developing rapport, and establishing a therapeutic alliance during telemental health practice. Clinical need and shortages of clinicians with expertise in evaluating mental conditions for children and adolescents in underserved communities have stimulated the rapid expansion of telemental health programs while the research base continues to develop. The emerging evidence base and clinical experience suggest that teleclinicians can, and do, build rapport and establish a therapeutic alliance during telemental health sessions with youth and families. Families may be more accepting of telemental health approaches than clinicians. The impact that technology, equipment, site staff, community supports, cultural identification, and teleclinicians' characteristics have on building rapport and establishing a therapeutic alliance should be considered when establishing a telemental health service. Staff at the patient site and referring providers have a valuable role in supporting the therapeutic alliance between telemental health providers and their patients, and ultimately supporting the success of a telemental health program. Teleclinicians are creative in transcending the videoconferencing technology to evaluate patients using guideline-based care. Further research is needed to determine how clinicians build rapport and establish a therapeutic alliance during telemental health sessions, and whether the therapeutic alliance is associated with the accuracy of evaluation and outcomes.

    2015-08-01

    The vast majority of guidelines recommend that developing rapport with children is essential for successful forensic child interviewing; however, the question remains as to whether there is a sufficient body of scientific research to generate evidence-based guidelines for developing rapport with children in legal contexts. To answer this question, we conducted a systematic review of the literature to identify experimental studies of the effects of rapport-building methods on the reliability of children's reports. Independent raters applied 12 exclusion criteria to the 2,761 potentially relevant articles located by electronic and hand searches of the literature. Experimental studies were few. Although studies to date are a beginning, the overall scientific base is weak regarding even basic issues such as how to best define rapport and the efficacy of common rapport-building techniques. This systematic review highlights what we know, what we do not know, and how much more we need to know to create evidence-based best practice. Recommendations for reshaping the research agenda are discussed. Copyright © 2015 John Wiley & Sons, Ltd.

  16. Testing the relationship between mimicry, trust and rapport in virtual reality conversations.

    Science.gov (United States)

    Hale, Joanna; Hamilton, Antonia F De C

    2016-10-14

    People mimic each other's actions and postures during everyday interactions. It is widely believed this mimicry acts as a social glue, leading to increased rapport. We present two studies using virtual reality to rigorously test this hypothesis. In Study 1, 50 participants interacted with two avatars who either mimicked their head and torso movements at a 1 or 3 second time delay or did not mimic, and rated feelings of rapport and trust toward the avatars. Rapport was higher towards mimicking avatars, with no effect of timing. In Study 2, we aimed to replicate this effect in a pre-registered design and test whether it is modulated by cultural ingroup-outgroup boundaries. Forty participants from European or East Asian backgrounds interacted with four avatars, two of European appearance and two of East Asian appearance. Two avatars mimicked while the other two did not. We found no effects of mimicry on rapport or trust ratings or implicit trust behaviour in a novel maze task, and no effects of group status or interactions. These null results were calculated in line with our pre-registration. We conclude that being mimicked does not always increase rapport or trust, and make suggestions for future directions.

    This study examined the quality of interview instructions and rapport-building provided by prosecutors to 168 children aged 5-12 years testifying in child sexual abuse cases, preceding explicit questions about abuse allegations. Prosecutors failed to effectively administer key interview instructions, build rapport, or rely on open-ended narrative producing prompts during this early stage of questioning. Moreover, prosecutors often directed children's attention to the defendant early in the testimony. The productivity of different types of wh- questions varied, with what/how questions focusing on actions being particularly productive. The lack of instructions, poor quality rapport-building, and closed-ended questioning suggest that children may not be adequately prepared during trial to provide lengthy and reliable reports to their full ability.

    Adults with autism spectrum disorder (ASD) and no intellectual disabilities were taught to increase the social play skills of children with ASD as part of a vocational training program. Participants included 3 adults, aged 21 to 27 years, and 6 children with ASD. Probes conducted throughout the study evaluated whether play skills training affected a measure of rapport between the adult and child. Results demonstrated the effectiveness of behavioral skills training for teaching the adult participants the appropriate play skills. In addition, the children's social engagement increased. Finally, rapport probes showed that play skills training increased levels of proximity, our measure of rapport, between the adults and children. © 2016 Society for the Experimental Analysis of Behavior.

    Full Text Available Ce texte développe une double idée. La première est que l’on peut parler de « rapport social de service », au sens plein du concept de « rapport social », en en assumant toutes les implications et en le différenciant nettement de la notion de « relation de service ». La seconde, qui découle de la première, est que l’on peut parler de « composition » entre rapports sociaux différents, non réductibles l’un à l’autre. Nous montrons ainsi qu’il existe une composition entre rapport social de service et rapport capital-travail, et que c’est à partir d’elle que l’on peut comprendre en quoi consiste le travail salarié de production de service et situer le rôle des clients, dans une perspective différente de celle issue du concept de « relation de service ».The text develops two ideas. The first is that it is possible to talk about “service-based social relationships” using the full meaning of the concept of a “social relationship” and accepting all of its implications while continuing to differentiate it from the “service relationship” construct. The second, which stems from the first, is that it is possible to talk about a “composition” based on different social relationships that cannot be reduced to one another. By so doing, what becomes apparent is that a composition does exist between a service-based social relationship and the capital-labour nexus. This is instructive as regards service production employment and situates customers’ roles in a different framework than one grounded in a “service relationship” construct.En este texto se desarrolla una idea con dos aspectos. El primero es que se puede hablar de “vínculo social de servicio” en el sentido pleno del concepto de “relación social”, asumiendo todas las implicaciones de dicho concepto y diferenciándolo claramente de la noción de “relación de servicio”.

  14. Investigating the complex structural integrity of the Zeit Bay Field, Gulf of Suez, Egypt, using interpretation of 3D seismic reflection data

    Afife, M.; Salem, M.; Aziz, M. Abdel

    2017-07-01

    Zeit Bay Field is one of the most important oil-bearing fields in the Gulf of Suez, Egypt, producing oil from the fractured basement rocks. Due to the complex structural setting of the area and the classical exploration concept that was based mainly on 2D seismic survey data, the area suffered from limited hydrocarbon interest for several years. During this time, most of the drilled wells hit structural highs and resulted in several dry holes. The present study is based on the interpretation of more recently acquired 3D seismic survey data as, matched with the available well logs, used to understand the complex structural setting of the Zeit Bay Field and provide insight into the entrapment style of the implied hydrocarbons. Several selected seismic cross sections were constructed, to extract subsurface geologic information, using available seismic profiles and wells. In addition, structure contour maps (isochronous maps, converted to depth maps) were constructed for the peaks of the basement, Nubian Sandstone, Kareem and Belayim Formations. Folds (anticlines and synclines) and faults (dip-slip) are identified on these maps, both individually and in groups, giving rise to step-like belts, as well as graben and horst blocks.

    2015-04-01

    Full Text Available Este artigo explora a influência do líder egípcio Gamal Abdel Nasser na América Latina. Na década de 1950, uma geração de intelectuais e políticos latino-americanos viram, no sucesso do emergente nacionalismo árabe, simbolizado por Nasser, um exemplo a imitar. No Panamá, a nacionalização egípcia do Canal de Suez, em 1956, desencadeou nova onda de demandas contra o controle e a posse do canal interoceânico pelos Estados Unidos. Em toda a região, frente ao aparecimento de regimes reacionários, intelectuais de esquerda enfatizaram a necessidade de um Nasser latino-americano; um caudilho moderno, que emergiria do interior das Forças Armadas imbuído de potente nacionalismo sem concessões e compromisso inegociável com o progresso social.

    Full Text Available An interpretation of the seismic data of Ras Budran and Abu Zenima oil fields, northern central Gulf of Suez, is carried out to evaluate its subsurface tectonic setting. The structural configuration, as well as the tectonic features of the concerned area is criticized through the study of 2D and 3D seismic data interpretation with the available geological data, in which the geo-seismic depth maps for the main interesting levels (Kareem, Nukhul, Matulla, Raha and Nubia Formations are depicted. Such maps reflect that, the Miocene structure of Ras Budran area is a nearly NE–SW trending anticlinal feature, which broken into several panels by a set of NWSE and NE–SW trending faults. The Pre-Miocene structure of the studied area is very complex, where Ras Budran area consists of step faults down stepping to the south and southwest, which have been subjected to cross faults of NE–SW trend with lateral and vertical displacements.

    Full Text Available El 17 de noviembre de 1869 tuvo lugar el solemne acto de inauguración del Canal de Suez. Largamente celebrado por los medios de información, el histórico acontecimiento atrajo visitantes de toda Europa, generando asimismo la promoción de varios viajes organizados. Tras una breve introducción sobre los principales hechos que condujeron a la apertura de la nueva ruta marítima, este artículo se ocupa de dos singulares proyectos de cruceros turísticos españoles, en una época en la que los viajes de recreo al extranjero, y el turismo en general, sólo proliferaban entre las élites foráneas. Su estudio ayuda a esclarecer, por otra parte, algunos rasgos diferenciales de las primeras experiencias crucerísticas en España, que habían empezado a llevarse a cabo desde mediados del siglo XIX.

  5. RAPPORT-BUILDING THROUGH CALL IN TEACHING CHINESE AS A FOREIGN LANGUAGE: AN EXPLORATORY STUDY

    Directory of Open Access Journals (Sweden)

    Wenying Jiang

    2005-05-01

    Full Text Available Technological advances have brought about the ever-increasing utilisation of computer-assisted language learning (CALL media in the learning of a second language (L2. Computer-mediated communication, for example, provides a practical means for extending the learning of spoken language, a challenging process in tonal languages such as Chinese, beyond the realms of the classroom. In order to effectively improve spoken language competency, however, CALL applications must also reproduce the social interaction that lies at the heart of language learning and language use. This study draws on data obtained from the utilisation of CALL in the learning of L2 Chinese to explore whether this medium can be used to extend opportunities for rapport-building in language teaching beyond the face-to-face interaction of the classroom. Rapport's importance lies in its potential to enhance learning, motivate learners, and reduce learner anxiety. To date, CALL's potential in relation to this facet of social interaction remains a neglected area of research. The results of this exploratory study suggest that CALL may help foster learner-teacher rapport and that scaffolding, such as strategically composing rapport-fostering questions in sound-files, is conducive to this outcome. The study provides an instruction model for this application of CALL.

    2017-07-01

    Full Text Available The level of natural radioactivity in 20 black sand and 20 sediment samples collected from Temsah Lake beaches of Suez Canal district, Egypt was investigated. The gamma-ray spectrometry system with hyper-pure germanium (HPGe detector has been used to determined radioactivity concentrations. Mathematical model is used to estimate the activity concentrations of 222Rn in the air with the activities of 226Ra. The activity concentrations of the sediment and black sand samples range from 4.29 ± 1.66 to 30.06 ± 8.80 and 4.29 ± 0.68 to 18.52 ± 5.22 Bq/kg for 226Ra. The ranges of radioactivity concentration of 232Th vary from 6.69 ± 1.54 to 39.24 ± 9.80 and 4.56 ± 1.07 to 18.65 ± 5.27 Bq/kg. The effective annual dose rate in the samples under study varies from 0.01 to 0.05 mSv/y for sediment samples and from 0.01 to 0.05 mSv/y for black sand samples. The concentrations of radon gas in the air were determined as well as the activity concentrations of 226Ra. Radon 222Rn doses from gas inhalation for humans were estimated to be in the range of 0.13–13.09 μsv/y for all samples. The activity concentrations of all samples, which were measured in the present work, were compared with the values in other countries in the world, and it was found they were within the permissible limits, which indicates that the study area was radiologically safe for humans.

    Classical magnetoresistance (MR) in nonmagnetic metals are conventionally understood in terms of the Kohler rule, with violation usually viewed as anomalous electron transport, in particular, as evidence of non-Fermi liquid behavior. Measurement of the MR of Au films as a function of temperature and film thickness reveals a strong dependence on grain size distribution and clear violation of the Kohler rule. Using a model of random resistor network, we show that this result can be explained if the MR arises entirely from inhomogeneity due to grain boundary scattering and thermal activation of grain boundary atoms. Consequently, the Kohler rule should not be used to distinguish normal and anomalous electron transport in solids.

A post-task evaluation of rapport and other related constructs followed each exchange. Four studies shared these same dependent measures, but asked distinct questions: Study 1 (Ndyad = 38 explored the influence of perceived responsibility and gender-specificity of the task; Study 2 (Ndyad = 51 focused on dyad sex-makeup; Studies 3 (Ndyad = 41 and 4 (Ndyad = 63 examined cognitive load impacts on the interactions. Versions of the data are structured with both individual and dyad as the unit of analysis. Our data possess strong reuse potential for theorists interested in dyadic processes and are especially pertinent to questions about dyad agreement and interpersonal perception / behavior association relationships.

    Full Text Available Cet article s’articule autour d’une source, le rapport préliminaire de la Commission royale d’enquête sur le bilinguisme et le biculturalisme, qui permet, à l’aide de bribes de témoignages de citoyens canadiens et de l’analyse des commissaires, de pénétrer les mémoires québécoise et canadienne, qui évoluent en vases clos. Paru en 1965, le rapport préliminaire révèle au grand jour l’intensité de la crise canadienne, une intensité telle qu’elle menace, aux yeux des commissaires, l’unité du pays. Comment se manifestent les traces du passé au sein du rapport ? Qu’est-ce que le document révèle sur les mémoires canadienne et québécoise ? Où la crise décrite par les commissaires puise-t-elle sa source ? Tels sont les questionnements qui nous intéresseront. À travers l’analyse du rapport préliminaire, se dégage toute la complexité des rapports canado-québécois. Se dégage également des pistes de solutions qui sont encore criantes d’actualité.This article is about a source, the Preliminary Report of the Royal Commission on Bilinguism and Biculturalism, that permits to enter, through the fragments of testimonies of Canadian citizens and their analysis by the commissers, in the Quebecers and Canadians’ memories, which evolve in two ways apart. Published in 1965, the Preliminary Report had the effect of a bomb in revealing the intensity of the Canadian crisis, which threatens, according to the commissers, the Canadian unity. How does the tracks of past manifest themselves within the report? What does the document reveal on the Canadian and Quebecois memories? Where does the crisis described by commissers draws its source? Such are the questionings which will interest us. Through the analysis of the preliminary report, all the complexity of the Canado-Quebecois connections is appearing. Also appears some solutions which are still of a profound actuality.

  9. Multifragmentation in Au + Au collisions studied with AMD-V

    1998-07-01

    AMD-V is an optimum model for calculation of multifragmentation in Au + Au collisions. AMD-V consider anti-symmetry of incident nucleus, target nucleus and fragments, furthermore, it treat the quantum effect to exist many channels in the intermediate and final state. 150 and 250 MeV/nucleon incident energy were used in the experiments. The data of multifragment atom in {sup 197}Au + {sup 197}Au collisions was reproduced by AMD-V calculation using Gognny force, corresponding to the imcompressibility of nuclear substance K = 228 MeV and its mean field depend on momentum. When other interaction (SKG 2 force, corresponding to K = 373 KeV) was used an mean field does not depend on momentum, the calculation results could not reproduce the experimental values, because nucleus and deuteron were estimated too large and {alpha}-particle and intermediate fragments estimated too small.

    Full Text Available Cette contribution portera sur l’étude du fonctionnement référentiel des pronoms démonstratifs dans les Mémoires de Jean-François de Retz et dans L’éducation sentimentale de Flaubert. Certes, nombreuses sont les études qui se sont intéressées à l’analyse de ce type de pronoms, mais notre apport vis-à-vis de tout ce qui a précédé consiste à mettre l’accent sur le processus de référenciation des pronoms démonstratifs et sur leur rôle dans l’organisation informationnelle. En partant d'exemples de phrases attestées, nous allons essayer de montrer qu’il est souvent difficile de résoudre certains rapports anaphoriques, essentiellement lorsqu’il s’agit de rattacher le pronom anaphorique à son antécédent. Notre but consiste également à montrer que les textes de la période classique sont difficilement interprétables par le lecteur moderne étant donné que ce dernier se trouve obligé de résoudre certains rapports anaphoriques ambigus qui agissent directement sur la cohérence textuelle et l’organisation informationnelle.

    2007-01-01

    Ce volume collectif sur le risque inaugure la collection L'ÉQUINOXE. Ancré dans l'histoire pour mesurer les continuités et les ruptures, il illustre la manière dont les sciences humaines évaluent et mesurent les enjeux collectifs du risque sur les plans politiques, scientifiques, énergétiques, juridiques et éthiques. Puisse-t-il nourrir la réflexion sur la culture et la prévention du risque. Ses formes épidémiques, écologiques, sociales, terroristes et militaires nourrissent les peurs actuelles, structurent les projets sécuritaires et constituent - sans doute - les défis majeurs à notre modernité. Dans la foulée de la richesse scientifique d'Equinoxe, L'ÉQUINOXE hérite de son esprit en prenant à son tour le pari de contribuer - non sans risque - à enrichir en Suisse romande et ailleurs le champ éditorial des sciences humaines dont notre société a besoin pour forger ses repères.

  5. Chiral magnetic effect search in p+Au, d+Au and Au+Au collisions at RHIC

    Science.gov (United States)

    Zhao, Jie; STAR Collaboration

    2017-09-01

    The chiral magnetic effect (CME) is a fundamental property of QCD. A major background source for CME measurements is the intrinsic particle correlations (such as resonances/jets decay) coupled with the azimuthal elliptical anisotropy v2. In heavy-ion collisions, the magnetic field direction and event plane azimuthal angle Ψ2 are correlated, thus the CME and the v2-induced background are entangled. In small system p+Au and d+Au collisions, the Ψ2 is mostly due to geometry fluctuations, and thus magnetic field direction and Ψ2 are uncorrelated. The correlation measurements in small system collisions with respect to Ψ2 are only sensitive to v2-induced background while any CME is averaged to zero. In this talk, we will present the STAR measurements of two-particle correlations with respect to Ψ2 in p+Au, d+Au and Au+Au collisions at √{sNN} = 200 GeV. These results are analyzed as a function of particle multiplicity to shed light on the background contaminations of the CME measurements in heavy-ion collisions. We will also report results from a new analysis approach as a function of the particle pair invariant mass in order to suppress non-CME related physics backgrounds.

  10. Borophene synthesis on Au(111)

    Science.gov (United States)

    Guisinger, Nathan; Kiraly, Brian; Zhang, Zhuhua; Mannix, Andrew; Hersam, Mark C.; Yakobson, Boris I.

    The recent experimental discovery of borophene, the metallic 2-dimensional allotrope of boron, has sparked tremendous interest in further exploration of this unique material. The initial synthesis of borophene was accomplished on Ag substrates and serves as a quintessential example of predictive modeling to experimental realization. In this talk, we expand the phase-space of borophene synthesis to Au. Borophene synthesis was accomplished by evaporating elemental boron onto a Au(111) substrate. The synthesized borophene retains its metallic character on Au as verified with scanning tunneling spectroscopy. Most fascinating is the difference in growth dynamics on the Au(111) substrate where the reconstructed surface presents a unique energy landscape for borophene nucleation and growth. We find that the initial low-coverage growth of borophene modifies the herringbone reconstruction into a ``trigonal'' network, where the 2D boron islands are uniformly templated across the surface. Increasing coverage results in the increasing size of the templated borophene islands until they coalesce into larger sheets. The observed growth dynamics are supported by the computational modeling of boron nucleation on Au.

La politique agricole a reflété les rapports de forces politiques et la capacité des élites agricoles alliées au Trône pour influencer les processus de décision. Cependant, les orientations traditionnelles de cette politique ont été remises en cause, depuis la fin des années quatre-vingt, par la libéralisation du commerce international et les contraintes financières du pays. Dans cet article, nous proposons d’apporter des éléments d’information sur l’évolution de cette politique et l’articulation des intérêts agricoles à travers le prisme de la trajectoire de l’Union Marocaine de l’Agriculture (UMA. Cette organisation professionnelle a prétendu, depuis sa constitution en 1958, au monopole de la représentation des intérêts des agriculteurs marocains, et donc du monde rural. Ce faisant, l’UMA a longtemps joué le rôle d’un véritable lobby agraire au sein des différentes institutions du royaume. Cependant, elle semble avoir perdu sa fonctionnalité à la fin des années quatre-vingt-dix, son rôle et son avenir étant depuis lors entourés d’incertitude.

    2011-01-01

    Full Text Available We describe a multiscale modeling hierarchy for the particular case of Au-island ripening on Au(100. Starting at the microscopic scale, density functional theory was used to investigate a limited number of self-diffusion processes on perfect and imperfect Au(100 surfaces. The obtained structural and energetic information served as basis for optimizing a reactive forcefield (here ReaxFF, which afterwards was used to address the mesoscopic scale. Reactive force field simulations were performed to investigate more diffusion possibilities at a lower computational cost but with similar accuracy. Finally, we reached the macroscale by means of kinetic Monte Carlo (kMC simulations. The reaction rates for the reaction process database used in the kMC simulations were generated using the reactive force field. Using this strategy, we simulated nucleation, aggregation, and fluctuation processes for monoatomic high islands on Au(100 and modeled their equilibrium shape structures. Finally, by calculating the step line tension at different temperatures, we were able to make a direct comparison with available experimental data.

    Buteau, Sylvie

    Le rechauffement climatique predit pour les prochaines decennies, aura des impacts majeurs sur le pergelisol qui sont tres peu documentes pour l'instant. La presente etude a pour but d'evaluer ces impacts sur les proprietes mecaniques du pergelisol et sa stabilite a long terme. Une nouvelle technique d'essai de penetration au cone a taux de deformation controle, a ete developpee pour caracteriser en place le pergelisol. Ces essais geotechniques et la mesure de differentes proprietes physiques ont ete effectues sur une butte de pergelisol au cours du printemps 2000. Le developpement et l'utilisation d'un modele geothermique 1D tenant compte de la thermodependance du comportement mecanique ont permis d'evaluer que les etendues de pergelisol chaud deviendraient instables a la suite d'un rechauffement de l'ordre de 5°C sur cent ans. En effet, la resistance mecanique du pergelisol diminuera alors rapidement jusqu'a 11,6 MPa, ce qui correspond a une perte relative de 98% de la resistance par rapport a un scenario sans rechauffement.

    Introduction L'objectif de ce travail était d’évaluer l'impact du traitement antirétroviral sur le profil biologique des enfants VIH positifs suivis au Centre Hospitalier et Universitaire de Yaoundé au Cameroun. Méthodes Il s'agissait d'une étude rétrospective réalisée de Mai 2003 à Décembre 2012 au CHU de Yaoundé au Cameroun. Pour cette étude, nous avons obtenu une clairance éthique. Résultats L’âge moyen était de 54.02±46.34 mois. The sexe ratio était de 0.96 en faveur des garçons. Le diagnostic s’était fait tardivement (74.2%) ainsi que la mise sous traitement (83.3%). Seuls 36 des 116 enfants (31%) avait pu avoir un bilan biologique à l'initiation du traitement antirétroviral et six mois après l'initiation du traitement antirétroviral. Après six mois de traitement, nous avons enregistrés une augmentation significative des paramètres biologiques suivants: taux de glycémie de 0.09g/L (0.75-0.84; p= 0.007), pourcentage de CD4 chez les enfants de moins de 5 ans de 4.62% (20.12-24.75; p = 0.022), valeur absolue de CD4 chez les enfants de plus de 5 ans de 294 cellules/mm3 (151.18-445.18; p = 0.011), le rapport CD4/CD8 de 0.35 (0.55-0.90; p = 0.000). Enfin, après six mois de traitement, on enregistrait une baisse significative de la charge virale du VIH de 3.90 log (5.85-1.95; p = 0.006). Conclusion Il ressort de cette étude que la restauration immunitaire et la suppression virologique peuvent être obtenus après six mois de traitement antirétroviral. Cependant, des efforts doivent encore être faits en ce qui concerne la prise en charge du suivi biologique, gage d'un bon suivi thérapeutique au Cameroun. PMID:26113902

    The system created in non-central relativisticnucleus-nucleus collisions possesses large orbital angular momentum. Dueto spin-orbit coupling, particles produced in such a system could becomeglobally polarized along the direction of the system angular momentum. Wepresent the results of Lambda and anti-Lambda hyperon global polarizationmeasurements in Au+Au collisions at sqrt sNN=62.4 GeV and 200 GeVperformed with the STAR detector at RHIC. The observed globalpolarization of Lambda and anti-Lambda hyperons in the STAR acceptance isconsistent with zero within the precision of the measurements. Theobtained upper limit, lbar P Lambda, anti-Lambda rbar<= 0.02, iscompared to the theoretical values discussed recently in theliterature.

    The object of this work is to investigate the conditions under which the activity of {beta}-emitting radionuclides may be measured with a maximum of precision, and as a result to study the relevant corrections. The various problems relating to activity measurements with a 4 {pi} counter have been examined successively: - comparison of 4 {pi}, GM and proportional counters; - study of the preparation of sources; - corrections on the counting of sources; - self-absorption; - correction for absorption. The precision obtained on these measurements varies from 1.2 to 3 per cent, with the result that the 4 {pi} counter can be considered a very satisfactory calibration instrument. (author) [French] Le but de ce travail est de rechercher les conditions permettant d'obtenir avec le maximum de precision, la mesure de l'activite des radionuclides se desintegrant par emission et par consequent d'etudier les corrections qui s'y rapportent. Nous avons examine successivement les differents problemes se rapportant aux mesures d'activite au compteur 4 {pi}: - Comparaison des compteurs 4 {pi}, GM et proportionnel; - etude de la preparation des sources; - corrections sur la numeration des sources; - auto-absorption; - correction d'absorption. La precision obtenue dans ces mesures, variant de 1,2 a 3 pour cent, on peut donc considerer le compteur 4 {pi} comme un instrument d'etalonnage tres satisfaisant. (auteur)

    In these proceedings, we discuss recent results from d + Au collisions in PHENIX ridge related measurements and their possible hydrodynamic origin. We present the v{sub 2} at midrapidity and measurements of the pseudorapidity dependence of the ridge, distinguishing between the d-going and Au-going directions. We investigate the possible geometrical origin by comparing v{sub 2} in d + Au to that in p + Pb, Au + Au and Pb + Pb collisions. Future plans to clarify the role of geometry in small collision systems at RHIC are discussed.

  13. Decay spectroscopy of $^{178}$Au

    CERN Document Server

    Whitmore, B

    In this thesis, the neutron-deficient nucleus $^{178}$Au is investigated through decay spectroscopy. Si and HPGe detectors were used to analyse the decay radiation of $^{178}$Au and its daughter nuclei. Previous studies have been unable to distinguish decay radiation from different isomeric states of this nucleus. This thesis represents the first time such isomeric discrimination has been achieved, and presents tentative spin assignments of both the ground state and an isomer. The neutron-deficient gold isotopes are an area of interest for the study of shape coexistence. This is the phenomenon exhibited by nuclei able to exist at a number of close lying energy minima, each reflecting a distinct type of deformation. It is hoped that studies such as this can help identify the evolution of nuclear deformation in this region of the nuclear chart.

    Introduction La péritonite infectieuse (PI) est une des complications les plus sévères et les plus fréquentes de la dialyse péritonéale (DP). But: Déterminer le taux des PI et les germes en causes, et évaluer l’efficacité des protocoles thérapeutiques entrepris chez les patients traités par DP au CHU de Rabat. Méthodes Etude rétrospective effectuée en Septembre 2009 chez tous les patients traités par DP continue ambulatoire (DPCA) au CHU de Rabat depuis l’ouverture de l’unité de DP en Juillet 2006. Ont été inclus dans cette étude, tous les patients ayant fait une péritonite. Pour tous nos patients, nous avons relevé les données cliniques, biologiques et bactériologiques. Nous avons également recherché les causes des péritonites, le délai de survenue par rapport au début de la dialyse, et la durée moyenne de formation des patients. Résultats Au cours de la période de l’étude, 28 épisodes de PI sont survenus chez 19 patients dont la moyenne d’âge est de 46±16 (19-78) ans, avec une prédominance masculine (12 hommes/ 7 femmes). Le taux des PI dans notre unité de DP est de 21.07 mois-patients calculé par le RDPLF. Leur délai de survenue par rapport au début de la dialyse au centre est de 7.9 ±8 (1-29) mois. Lors de ces PI, les bactéries à Gram négatif (BGN) ont été retrouvées dans 55% des cas, contre uniquement 45% pour les Gram positifs. Conclusion La PI est une complication grave et redoutable de la DP. Le taux de PI dans notre centre de DPCA est de 21m-p ce qui correspond au taux acceptable définie par les sociétés internationales. Les germes les plus responsables des PI dans notre centre sont les BGN et la contamination semble être manu-portée se faisant essentiellement à partir de la flore environnementale et cutanée.

  18. Fabricating a Homogeneously Alloyed AuAg Shell on Au Nanorods to Achieve Strong, Stable, and Tunable Surface Plasmon Resonances

    KAUST Repository

    Huang, Jianfeng

    2015-08-13

    Colloidal metal nanocrystals with strong, stable, and tunable localized surface plasmon resonances (SPRs) can be useful in a corrosive environment for many applications including field-enhanced spectroscopies, plasmon-mediated catalysis, etc. Here, a new synthetic strategy is reported that enables the epitaxial growth of a homogeneously alloyed AuAg shell on Au nanorod seeds, circumventing the phase segregation of Au and Ag encountered in conventional synthesis. The resulting core–shell structured bimetallic nanorods (AuNR@AuAg) have well-mixed Au and Ag atoms in their shell without discernible domains. This degree of mixing allows AuNR@AuAg to combine the high stability of Au with the superior plasmonic activity of Ag, thus outperforming seemingly similar nanostructures with monometallic shells (e.g., Ag-coated Au NRs (AuNR@Ag) and Au-coated Au NRs (AuNR@Au)). AuNR@AuAg is comparable to AuNR@Ag in plasmonic activity, but that it is markedly more stable toward oxidative treatment. Specifically, AuNR@AuAg and AuNR@Ag exhibit similarly strong signals in surface-enhanced Raman spectroscopy that are some 30-fold higher than that of AuNR@Au. When incubated with a H2O2 solution (0.5 m), the plasmonic activity of AuNR@Ag immediately and severely decayed, whereas AuNR@AuAg retained its activity intact. Moreover, the longitudinal SPR frequency of AuNR@AuAg can be tuned throughout the red wavelengths (≈620–690 nm) by controlling the thickness of the AuAg alloy shell. The synthetic strategy is versatile to fabricate AuAg alloyed shells on different shaped Au, with prospects for new possibilities in the synthesis and application of plasmonic nanocrystals.

    Cloud computing infrastructure is now widely used in many domains, but one area where there has been more limited adoption is research computing, in particular for running scientific high-performance computing (HPC) software. The Robust Application Porting for HPC in the Cloud (RAPPORT) project took advantage of existing links between computing researchers and application scientists in the fields of bioinformatics, high-energy physics (HEP) and digital humanities, to investigate running a set of scientific HPC applications from these domains on cloud infrastructure. In this paper, we focus on the bioinformatics and HEP domains, describing the applications and target cloud platforms. We conclude that, while there are many factors that need consideration, there is no fundamental impediment to the use of cloud infrastructure for running many types of HPC applications and, in some cases, there is potential for researchers to benefit significantly from the flexibility offered by cloud platforms.

  1. Eating Animals to Build Rapport: Conducting Research as Vegans or Vegetarians

    Directory of Open Access Journals (Sweden)

    Katie MacDonald

    2014-12-01

    Full Text Available Notions of hospitality, community, and the fostering of rapport and connection are foundational concerns for conducting research across difference. Drawing on methodological literature, this paper considers how access to various communities and “good” data is structured by the notion that in order to develop rapport researchers accept the “food”, specifically “meat” offered by their hosts. When researchers are vegetarians or vegans, this can entail a conflict in which questions of hospitality, relationships, and responsibility to ethical commitments come to the fore. As such, we analyze methodological literature in which the logic of nonhuman animal sacrifice is considered a means to the ends of research through the development of “rapport”—often coded as an ethical relationship of respect to the participant. We draw on experiences of veg*n researchers to explore how this assumption functions to position the consumption of meat as a necessary undertaking when conducting research, and in turn, denies nonhuman animal subjecthood. We interrogate the assumption that culture and communities are static inasmuch as this literature suggests ways to enter and exit spaces leaving minimal impact, and that posits participants will not trust researchers nor understand their decisions against eating nonhuman animals. We argue that because food consumption is figured as a private and individual choice, animals are not considered subjects in research. Thus, we articulate a means to consider vegan and/or vegetarians politics, not as a marker of difference, but as an attempt to engage in ethical relationships with nonhuman animals. In so doing, we call for the inclusion of nonhuman animals in relationships of hospitality, and thereby attempt to politicize the practice of food consumption while conducting research.

    We have used scanning and transmission electron microscopes (SEM and TEM) to study the structure of a pentacene thin film grown on a Au layer with and shown that it consists of randomly oriented amorphous pentacene clusters. We have also investigated the transport properties of amorphous pentacene in a metal–semiconductor–metal (MSM) diode structure and shown that the current is logarithmically proportional to the square root of the applied voltage, which indicates that transport occurs as the result of hopping between localized sites randomly distributed in space and energy.

    Introduction L'objectif de ce travail était de déterminer les facteurs influençant l'initiation au traitement antirétroviral des personnes vivant avec le VIH (PVVIH) dans les centres de traitements agrées (CTA) de Bamenda et de Bertoua au Cameroun. Méthodes Il s'agissait d'une étude transversale, analytique réalisée de Janvier à Avril 2011, dans les CTA de Bamenda et de Bertoua. Pour cette étude, nous avons obtenu une clairance éthique. Résultats Nous avons étudiés 460 dossiers de patients séropositifs en phase d'initiation au traitement antirétroviral dans les CTA de Bamenda et de Bertoua, 53,9% et 46,1% respectivement. L ‘âge médian était de 36 ans. La plupart des séropositifs à Bertoua (41) avaient fait un dépistage volontaire du VIH par rapport à ceux de Bamenda (22) (p= 0.008). Il y ‘avait plus de VIH de type 1 et 2 dans le CTA de Bamenda (15) par rapport à Bertoua (3) (p= 0.011). La majorité des patients était classé au stade clinique II à Bamenda (54,0%) tandis qu ‘à Bertoua le stade clinique III était prédominant (52,4%) (p = 0,000). Le taux médian de CD4 était de 133 cellules/mm3 dans le CTA de Bamenda et de 175 cellules/mm3 à Bertoua (p = 0,008). La Zidovudine était plus prescrit à Bamenda et le Ténofovir à Bertoua (p = 0,000). L ‘Efavirenz était plus prescrit à Bertoua tandis que la Névirapine l ‘était plus à Bamenda (p = 0,000). Le Lopinavir/r était plus prescrit à Bamenda qu ‘à Bertoua (p = 0,017). Conclusion Il apparait urgent de standardiser la prise en charge des PVVIH dans les CTA du Cameroun. PMID:25184023

    The interplay of nuclear effects on the p(T)>2 GeV inclusive hadron spectra in d+Au and Au+Au reactions at sqrt[s(NN)]=17, 200, and 5500 GeV is compared to leading order perturbative QCD calculations for elementary p+p (p+p) collisions. The competition between nuclear shadowing, Cronin effect, and jet energy loss due to medium-induced gluon radiation is predicted to lead to a striking energy dependence of the nuclear suppression/enhancement pattern in A+A reactions. We show that future d+Au data can be used to disentangle the initial and final state effects.

    Full Text Available PHENIX measurements of high transverse momentum (pT identified hadrons in d+Au and Au+Au collisions are presented. The nuclear modification factors (RdA and RAA for π0 and ƞ are found to be very consistent in both collision systems, respectively. Using large amount of p + p and Au+Au datasets, the fractional momentum loss (Sloss and the path-length dependent yield of π0 in Au+Au collisions are obtained. The hadron spectra in the most central d+Au and the most peripheral Au+Au collisions are studied. The spectra shapes are found to be similar in both systems, but the yield is suppressed in the most peripheral Au+Au collisions.

    Au38(SR)24 is one of the most extensively investigated gold nanomolecules along with Au25(SR)18 and Au144(SR)60. However, so far it has only been prepared using aliphatic-like ligands, where R = -SC6H13, -SC12H25 and -SCH2CH2Ph. Au38(SCH2CH2Ph)24 when reacted with HSPh undergoes core-size conversion to Au36(SPh)24, and existing literature suggests that Au38(SPh)24 cannot be synthesized. Here, contrary to prevailing knowledge, we demonstrate that Au38(SPh)24 can be prepared if the ligand exchanged conditions are optimized, under delicate conditions, without any formation of Au36(SPh)24. Conclusive evidence is presented in the form of matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS), electrospray ionization mass spectra (ESI-MS) characterization, and optical spectra of Au38(SPh)24 in a solid glass form showing distinct differences from that of Au38(S-aliphatic)24. Theoretical analysis confirms experimental assignment of the optical spectrum and shows that the stability of Au38(SPh)24 is not negligible with respect to that of its aliphatic analogous, and contains a significant component of ligand-ligand attractive interactions. Thus, while Au38(SPh)24 is stable at RT, it converts to Au36(SPh)24 either on prolonged etching (longer than 2 hours) at RT or when etched at 80 °C.

  6. The use of Clay minerals in stratigraphic correlations of carboniferous coal deposits. Les mineraux argileux au service des correlations stratigraphiques des formations houilleres du Carbonifere; Rapport final

    Lorenzi, G.; Bossiroy, D.; Dreesen, R. (ISSeP, Liege (Belgium))

    1992-01-01

    The main objective of this research project has been achieved: the development of a new tool for the lithostratigraphical correlation of cored boreholes. The proposed technique is based on the processing and interpretation of the results of mineralogical analyses, carried out on the clay minerals from finegrained siliciclastic rocks, associated with coal seams. For this study, the stratigraphical interval below and above the Quaregnon Marine Band (limit between the Westphalian A and B), and more precisely the rock sequence between coal seams no KS 71 and 44 was selected: this interval has been recorded in several cored boreholes, north of the actual exploitation limits of the Beringen and Zolder-Houthalen collieries (Belgian Campine). Over 1000 samples (mainly from mudstones, some siltstones and sandstones) were taken out of the cores, at a regular spacing (about 2m), for further mineralogical analysis. Simultaneously, a sedimentological study was carried out on the the sampled sequences, as well as a petrographical analysis of the main rock types. This resulted in a reconstruction of the Westphalian depositional environments and in a better knowledge of the 'behaviour' (geological history) of the clay minerals. The mineralogical composition of the clay minerals was identified through X-ray diffraction and computer-aided graphical processing of the resulting data produced percentage or intensity ratio curves, which could then be used as a lithostratigraphical correlation tool. Correlations have been shown between relatively simple rock sequences (without split seams) in neighbouring boreholes (1 to 3 km apart) and positive correlations revealed between more complex sequences containing multiple coals seams. Some positive but less obvious correlations have also been discovered between sequences from widely spaced boreholes ({+-}10 km apart).

    2006-07-01

    This report aims at presenting the scientific evaluation activities carried out at the CEA during the years 2005-2006. The evaluation system is described in detail. It comprises two aspects: the evaluation of the scientific policy implemented by the scientific Council and by the visiting committee of the CEA, and the evaluation of the laboratories, performed by a pool of 36 scientific councils. The evaluation by external and independent parties is the key point of this system. This document makes a status of the evaluations performed in 2005 and 2006. It presents a synthesis of the conclusions of the evaluation authorities. The actions implemented by the CEA to take into consideration the recommendations are also reported with the improvements noticed. The two topics examined by the scientific Committee and by the visiting committee were dealing with the energy domain, which is a strategic issue for the CEA. The examination of the researches on future nuclear reactors and on new energy technologies have shown the major role played by the CEA in the recent advances in these domains. About 95% of the laboratories activity was examined during the 2002-2005 period. The richness of the remarks and recommendations made by the scientific councils should allow the CEA to improve the quality and relevance of its research works. The start-up of the 2006-2009 evaluation cycle has been the occasion to modify the evaluation of some research domains in order to take into account the evolution of programs. The evaluation system of the CEA is highly consistent with the AERES principles. Its implementation, adapted to each type of activity (fundamental research, applied research, technological developments) allows the CEA to follow up a permanent improvement approach. (J.S.)

    To improve anaerobic digestion of pig manure, solubilization of the solid fraction was studied as the rate limiting step in the biomethanation process in an experimental completely mixed digester. The performance of conventional digesters should anaerobic microflora were inefficient in degrading complex biopolymers such as plant fibers. For pectin or cellulose, the use of digestible co-substrates accelerated methanation by increasing the yield of methane and a doubling of the apparent first order solubilization rate constant (Kp = 0.090/d). Lignin should methanation by decreasing methane yield and reducing the rate constant (Kp = 0.035/d). This inhibition was unrelated to volatile fatty acid accumulation. Nine strains of pectinolytic and/or cellulolytic bacteria were isolated. Chitin, a structural constituent of many final species, was effectively solubilized dining anaerobic digestion of pig manure. Seven strains of chitinolytic bacteria were isolated by high chitnese activity. The mycolytic power of fermenting manure processes acting through lytic microflora has been shown to be an effective antagonist of soil borne phytopathogenic fungi, as well as a fertilizer. In greenhouse trails, this compiled fraction demonstrated its ability to control flux unit. Keratin enhanced methane production, and increased H{sub 2}S nearly six-fold. Bacterial strains able to solubilize keratin were also used in autoclawed feather meal to extract the amino acids. (KJD)

    Following the seism that occurred on the 16. july 2007 in Japan (magnitude 6.6 on Richter scale), an IAEA mission has inspected the nuclear power plant of Kashiwazaki Kariwa at the beginning of August. The mission has estimated that the safety of the installation has been provided during and after the earthquake, in spite of the fact that the earthquake has gone past the seism level taken as reference in the conception of the nuclear facility. The systems and the components were in a better state that it could be imagined after a such earthquake. The release have been under the authorised thresholds. At the moment of the seism, three reactors were running on the seven ones of the nuclear power plant, and stopped automatically. The unit 2 that started up, has also stopped automatically. The reactors 1, 5 and 6 were stopped for maintenance. Water poured out coming from the spent fuel storage pool because of the earth tremors. It was picked and thrown out by the release pipe to the sea without notable impact on environment ( volume 1.2 m{sup 3}). One hundred of containers was overturned. Traces of iodine, chromium 51 and cobalt 60 have been found in the ventilation filters ( reactor 7) these elements have been released in atmosphere in very low quantities. (N.C.)

  10. Fostering future organization of French Electric Power. A report to Prime Minister; Reussir la future organisation electrique francaise. Rapport au Premier Ministre

    Energy Technology Data Exchange (ETDEWEB)

    Dumont, Jean Louis [Assemblee Nationale, Paris (France)

    1998-07-02

    This report addressed to the prime minister deals with the main four issues relating to the problem of revamping the French electricity sector. These are featured as: 1. The public electricity supply; 2. The future development of 'Electricite de France'; 3. The social renovation of the electricity sector; 4. Management and the role of policy. In turn these four chapters are detailed. Thus the first one addresses the problems: 1. Customizing the general interest supply; 2. Electricity general supply and the state policy; 3. Sustaining innovation, environmental protection and energy management; 4. The transport and distribution grid, the resistance structure of the public supply. Also, this chapter describes the role of the operators in the public electricity supply and tackles the problem of financing the commitments of the public supply. The second chapter sketches the tasks and management of EDF, considers establishing an agency to ensure accounting transparency, discusses the major significance of local collectivities and personnel. The third chapter addresses the following issues: 1. The range of application of the statute of electric and gas industries; 2. Adaptation of the statute; 3. Development of the statute; 4. Pensioners. The forth chapter deals with the definition of regulation, i.e. the management of the network authority and makes proposals for constituting relating commissions. In conclusion, the author pleads for maintaining and developing a major national operator ensuring public supply requirements as well as promotion of French electricity industry. The proposals made by the report's author concerning the operational ways of renewing the nuclear sector, the management of grid of electric transport, the role of local collectivities, creation of a professional trade, the founding regulation commissions and others are thought to prepare France to cope efficiently to the international competition in the years to come. The report is completed by two appendices containing the proposals of the author and a list of the persons interviewed during the mission.

    1998-12-31

    This report from the French Deputy of the Meuse region aims at taking stock of four main questions raised by the future organization of the French electric power industry in the context of the opening of the European power market: the public utility of electric power, the future missions of Electricite de france (EdF) company, the questions in relation with the personnel status in the electric power industry, and the status of the regulating authority. In order to give some elements of answer to these questions, the report has been divided into 2 parts: part 1 presents the power production, transport and distribution in the future electric power regulation (the renewal of nuclear facilities, the building of non-nuclear units, the exploitation of the power distribution network, the accounting dissociation and the transparency of accountancy, the organization of network access, the eligible clients, the direct power lines, the obligations of purchase, the distribution and the role of local authorities). Part 2 presents the four main stakes of the modernization of the French electric power sector: the electric power public utility (public concern and rights, government policy, sustain of innovation, environment protection and energy mastery, the transportation and distribution networks, the role of operators and the financing), the future evolution of EdF (missions and organization, future of the public company), the social modernization of the electric power sector (present day status, adaptation, evolution, pensions), the organization and role of the future regulation authority. The propositions of the author are reported in the appendix. (J.S.)

    The article 6 of the law from February 10, 2000, relative to the modernization and development of the electric utility, schedules a pluri-annual planning of the production investments (PPI) which represents a concrete translation of the energy policy in the domain of electricity. The PPI will allow to reach the energy policy goals using a balanced development of the national production means in terms of primary energy sources, techniques of production and geographical distribution of investments. This document is the first PPI report to the parliament. It is based on the scheme of energy collective services and on a provisional status made by the manager of the transportation network (RTE). In 2010, renewable energies should cover 21% of the French electricity needs. This ratio will be reached mainly thanks to the development of wind power (7000 to 14000 MW of installed power, which represents 20 to 35 TWh of additional production). Hydro-power should be increased of 8 TWh max, depending on the public policies implemented, and biomass will have a significant contribution too. On the other hand, actions of mastery of the electricity demand will have to be implemented. From 2008 onward, the decommissioning of several power plants will impose to find new solutions to satisfy the peak power needs. The covering of consumption peaks requires a correlation study of the power peaks at the European scale. Finally, the situation of non-interconnected areas and of areas with fragile supply has been carefully considered. The creation of new power production means must be envisaged in most of these areas.

    Participatory medicine and the availability of commercial technologies have given patients more options to view and track their health information and to communicate with their providers. This shift in the clinical process may be of particular importance in mental healthcare where rapport plays a significant role in the therapeutic process. In this review, we examined literature related to the impact of technology on the clinical workflow and patient-provider rapport in the mental health field between January 2014 and June 2017. Thirty three relevant articles, of 226 identified articles, were summarized. The use of technology clinically has evolved from making care more accessible and efficient to leveraging technology to improve care, communication, and patient-provider rapport. Evidence exists demonstrating that information and communication technologies may improve care by better connecting patients and providers and by improving patient-provider rapport, although further research is needed.

    2016-08-01

    We present recent PHENIX results for long-range two-particle correlation functions across a large pseudorapidity(η) gap in high-multiplicity p+Au, d+Au and 3He+Au collisions. Enhanced correlations are observed for particles with small azimuthal separation. Measurements of the second order Fourier coefficients (v 2) in p/d/3He+Au collisions, and the third order Fourier coefficient (v 3) in 3He+Au collision are performed using the event plane method. Scaling of v 2 with the initial eccentricity (ɛ 2) is performed in each system to investigate the role of the initial geometry in the development of a final-state anisotropy in the particle emission. The v 2 coefficients for identified π±, K± and (anti-)proton are measured as a function of transverse kinetic energy (KET) and their magnitudes are found to scale approximately with the number of constituent quarks in the hadron.

    2016-03-01

    Full Text Available Les partenariats public-privé (PPP sont un phénomène relativement récent dans le secteur de l’irrigation ; le projet El Guerdane au Maroc est ainsi le premier de son genre. Inauguré en 2008, le projet alimente en eau 10 000 ha de plantations d’agrumes. Les banques internationales de développement le présentent comme un succès, mais l’impact sur le développement local est, au mieux, mitigé. Alors que certains agriculteurs ont bénéficié de cette initiative, d’autres ont été marginalisés, en termes d’accès à l’eau, aux terres fertiles et au développement. Fondé sur des recherches de terrain extensives conduites entre 2005 et 2013, l’article révèle trois problèmes cruciaux du projet PPP : des effets souvent négatifs sur les revenus des acteurs et sur le développement ; un partage inégal des coûts, des bénéfices et des risques entre les secteurs public et privé ; un impact environnemental incertain. Sur la base de ces résultats, l’étude situe le projet dans le contexte plus large de l’évolution des rapports de force politico-économiques au Maroc.

  20. Comparative study of anchoring groups for molecular electronics: structure and conductance of Au-S-Au and Au-NH{sub 2}-Au junctions

    The electrical properties of single-molecule junctions, consisting of an organic molecule coupled to metal electrodes, are sensitive to the detailed atomic structure of the molecule-metal contact. This, in turn, is determined by the anchoring group linking the molecule to the metal. With the aim of identifying and comparing the intrinsic properties of two commonly used anchoring groups, namely thiol and amine groups, we have calculated the atomic structure and conductance traces of different Au-S-Au and Au-NH{sub 2}-Au nanojunctions using density functional theory (DFT). Whereas NH{sub 2} shows a strong structural selectivity towards atop-gold configurations, S shows large variability in its bonding geometries. As a result, the conductance of the Au-NH{sub 2}-Au junction is less sensitive to the structure of the gold contacts than the Au-S-Au junction. These findings support recent experiments which show that amine-bonded molecules exhibit more well-defined conductance properties than do thiol-bonded molecules.

    Ni/Au plated finishes used on thick-film metallized multilayer ceramic packages for integrated circuits must meet functional requirements such as bondability, sealability, and solderability. Their ability to do so is dependent, among other things, on the ability of the Au deposit to inhibit the grain boundary diffusion and subsequent surface oxidation of Ni. In this study, the relation between functional performance, Ni diffusionr ate, and Au microstructure was examined. Extent of Ni diffusion during heating was determined by Auger electron spectroscopy for several electrolytic and electroless Ni/Au finishing processes. Results were correlated with differences in Au microstructures determined by SEM, atomic force microscopy, and XRD.

    The structure of the recently discovered Au130-thiolate and -dithiolate clusters is explored in a combined experiment-theory approach. Rapid electron diffraction in scanning/transmission electron microscopy (STEM) enables atomic-resolution imaging of the gold core and the comparison with density functional theory (DFT)-optimized realistic structure models. The results are consistent with a 105-atom truncated-decahedral core protected by 25 short staple motifs, incorporating disulfide bridges linking the dithiolate ligands. The optimized structure also accounts, via time-dependent DFT (TD-DFT) simulation, for the distinctive optical absorption spectrum, and rationalizes the special stability underlying the selective formation of the Au130 cluster in high yield. The structure is distinct from, yet shares some features with, each of the known Au102 and Au144/Au146 systems.

    Irradiation of AuCl(4)(-) and AuCl(2)(OH)(2)(-) in the gas-phase using ultraviolet light (220-415 nm) leads to their dissociation. Observed fragment ions for AuCl(4)(-) are AuCl(3)(-) and AuCl(2)(-) and for AuCl(2)(OH)(2)(-) are AuCl(2)(-) and AuClOH(-). All fragment channels correspond to photoreduction of the gold atom to either Au(II) or Au(I) depending on the number of neutral ligands lost. Fragment branching ratios of AuCl(4)(-) are observed to be highly energy dependent and can be explained by comparison of the experimental data to calculated threshold energies obtained using density functional theory. The main observed spectral features are attributed to ligand-to-metal charge transfer transitions. These results are discussed in the context of the molecular-level mechanisms of Au(III) photochemistry.

    The Alto project means the installation of an electron linear accelerator inside the experimental area of the tandem accelerator of the nuclear physics institute of Orsay (IPNO, France). This linear accelerator comes from CERN where it was operating as a pre-injector for LEP. This equipment will allow IPNO'teams to perform fast kinetics studies in a domain different from that of ELYSE accelerator. The time resolution will not be as high as that of ELYSE (picosecond) but will be sufficient (microsecond) to produce free radicals in aqueous and gaseous media. The main expectations of this installation can be classified according 3 axis: 1) basic research (mainly the study of nuclear matter through photo-fission, 2) research and development of accelerators (by providing a test bench for new high frequency systems and superconducting components), and 3) applied research for industry concerning: biochemistry under irradiation, radiation sensibility, DNA breaking, food and drug sterilization and behaviour of electronic components under irradiation. This rapport details the research program that could be achieved with this equipment, describes its contributions in terms of economic development, cooperation with industry, student training, and specifies the needed investment and the operating and maintenance costs.

    Dans le monde, la leishmaniose viscérale humaine est connue pour avoir comme principale source d'infection les Canidés domestiques et sauvages. Au centre du Maroc, les données épidémiologiques, cliniques et parasitologiques sur la leishmaniose canine, sont quasiment inexistantes. Ce travail traite une étude prospective au cours de laquelle 61 sérums canins ont été analysés par un test rapide et par l'immunofluorescence indirecte. La sensibilité du test rapide par rapport à celle de l'immunofluorescence indirecte (IFI) est de 33,33%. La fréquence de la maladie chez les chiens s’élève à 9,83% (Test Rapide) et 24,59% (IFI). 73,33% des cas canins positifs à la sérologie sont asymptomatiques. Ce sont les jeunes chiens de moins de 5 ans qui sont les plus fréquemment atteints avec une sensibilité de la race Berger Allmand à l'infection. Cette étude a permis de mettre en évidence la présence de chiens leishmaniens (15 chiens séropositifs parmi 61) et de prouver l'existence du réservoir canin. Une stratégie de prévention active doit être mise en place. PMID:25852791

  14. Etude de la production de photons isolés dans les états finals hadroniques des collisions e+e- au LEP dans l'expérience ALEPH

    Si Mohand, D

    Les photons isolés, observés dans les désintégrations hadroniques du bozon Z0 créé dans les annihilations électron-positron au LEP, proviennent essentiellement du rayonnement électromagnétique des quarks. Ces photons, qui ne sont pas affectés par la fragmentation, sont particulièrement sensibles à l'émission de gluons; leur étude, à l'aide d'algorithmes de simulation tels que JETSET, ARIADNE et HERWIG, constitue un moyen simple et précis de tester les différentes approches de QCD, en particulier dans la description de la compétition photon-gluon. Notre analyse a révélé que JETSET prédit (20±6)% moins de photons directs que le nombre mesuré expérimentalement. ARIADNE, en revanche, semble surestimer légèrement le taux de production de photons directs de (6±4)% alors que HERWIG reproduit fidèlement l'ensemble de nos mesures.

The EIS data exhibited linear capacitive behaviour at 0.0 V with either MPA or DMSA added directly to the electrolyte suggesting the formation of an adsorbed layer of the alkylthiol on the electrode surface. Above this potential, a single well-defined impedance loop appeared for electrolyte solutions containing DMSA or MPA, an observation indicative of a charge transfer reaction that could be related to several processes including oxidative desorption, oxidation of the alkylthiol, or Au oxidation/dissolution. To test for Au dissolution, the electrode was held at 0.8 V vs. Ag/AgCl for 12 h in electrolytes containing MPA or DMSA followed by surface analysis with Atomic Force Microscopy and solution analysis with Atomic Absorption Spectroscopy. When the electrolyte contained MPA, the extended potential holding procedure resulted in significant roughening of the electrode with no detectable quantities of Au in the electrolyte. X-ray photoelectron spectroscopy (XPS) analysis of the Au surface revealed an additional species in the Au 4f{sub 7/2} spectrum indicating the presence of an insoluble electrochemically generated Au(I)-MPA species. When the electrolyte contained DMSA, the Au electrode appeared smoother, 56.6 {+-} 9.6 ppb of Au was detected in the electrolyte and the XPS analysis displayed a single species in the

  16. Au/Au@polythiophene core/shell nanospheres for heterogeneous catalysis of nitroarenes.

    Monodisperse Au/Au@polythiophene core/shell nanospheres were facilely prepared through the reduction of gold precursor, AuCl₄⁻, by 2-thiopheneacetonitrile in an aqueous solution. Concomitantly, 2-thiopheneacetonitrile polymerized during this redox process. As a result, Au nanoparticle was encapsulated by conductive polymer shell to afford novel core/shell nanospheres. Interestingly, the shell was composed of very tiny Au nanoparticles surrounded with thiophene polymers. Thus, the new material is best described as Au/Au@polythiophene core/shell nanospheres. FT-IR spectroscopy revealed that the Au nanoparticles were coordinated by the C≡N groups of the polythiophene shell. Some of the C≡N groups were partially hydrolyzed into COOH groups during the redox process because of the acidic reaction condition. The shell was conductive based on the typical ohmic behavior found in electrical measurement. The Au/Au@polythiophene core/shell nanospheres were found to be very active catalysts for the hydrogenation of various nitroarene compounds into corresponding aminoarene compounds in the presence of NaBH₄. Both hydrophilic and hydrophobic nitroarenes were efficiently hydrogenated under mild conditions.

  19. Synthesis of ultrathin face-centered-cubic Au@Pt and Au@Pd core-shell nanoplates from hexagonal-close-packed Au square sheets

    2015-03-17

    The synthesis of ultrathin face-centered-cubic (fcc) Au@Pt rhombic nanoplates is reported through the epitaxial growth of Pt on hexagonal-close-packed (hcp) Au square sheets (AuSSs). The Pt-layer growth results in a hcp-to-fcc phase transformation of the AuSSs under ambient conditions. Interestingly, the obtained fcc Au@Pt rhombic nanoplates demonstrate a unique (101)f orientation with the same atomic arrangement extending from the Au core to the Pt shell. Importantly, this method can be extended to the epitaxial growth of Pd on hcp AuSSs, resulting in the unprecedented formation of fcc Au@Pd rhombic nanoplates with (101)f orientation. Additionally, a small amount of fcc (100)f-oriented Au@Pt and Au@Pd square nanoplates are obtained with the Au@Pt and Au@Pd rhombic nanoplates, respectively. We believe that these findings will shed new light on the synthesis of novel noble bimetallic nanostructures. Phase change: Ultrathin Au@Pt and Au@Pd core-shell nanoplates were prepared from Au square sheets. A phase transformation from hexagonal close-packed (hcp) to face-centered cubic (fcc) is observed upon coating the hcp Au square sheets with Pt or Pd under ambient conditions. The prepared fcc Au@Pt and Au@Pd rhombic nanoplates demonstrate unique (101)f orientation (picture shows a typical fcc Au@Pt rhombic nanoplate). © 2015 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

    Three Au-based nanomaterials (silica-Au nanoshells, hollow Au/Ag nanospheres and Au nanorods) were evaluated for their comparative photothermal efficiencies at killing three types of malignant cells (A549 lung cancer cells, HeLa cervix cancer cells and TCC bladder cancer cells) using a CW NIR laser. Photodestructive efficiency was evaluated as a function of the number of nanoparticles required to destroy the cancer cells under 808 nm laser wavelength at fixed laser power. Of the three nanomaterials, silica/Au nanoshells needed the minimum number of particles to produce effective photodestruction, whereas Au nanorods needed the largest number of particles. Together with the calculated photothermal conversion efficiency, the photothermal efficiency rankings are silica-Au nanoshells > hollow Au/Ag nanospheres > Au nanorods. Additionally, we found that HeLa cells seem to present better heat tolerance than the other two cancer cell lines.

    Initial eccentricity and eccentricity fluctuations of the interaction volume created in relativistic collisions of deformed {sup 197}Au and {sup 238}U nuclei are studied using optical and Monte-Carlo (MC) Glauber simulations. It is found that the non-sphericity noticeably influences the average eccentricity in central collisions and eccentricity fluctuations are enhanced due to deformation. Quantitative results are obtained for Au+Au and U+U collisions at energy {radical}s{sub NN} = 200 GeV.

    As an emerging 2D material, graphene's several unique properties, such as high electron mobility, zero-bandgap and low density of states, present new opportunities for light detections. Here, we report on photovoltage responses of graphene-Au heterojunctions, which are made of monolayer graphene sheets atop Au electrodes designed as finger-shape and rectangle-shape, respectively. Besides confirming the critical role of space charge regions located at the graphene-Au boundary, photovoltage responses are measured in the visible to infrared spectral region with a cut-off wavelength at about 980 nm, which is likely imposed by the Pauli blocking of interband transition in the contact-doped graphene. The photoresponsivity is shown to decrease with increasing wavelength. A band diagram of the graphene-Au heterojunction is proposed to understand the photoresponse mechanism.

    2017-08-21

    Ligand-protected Au clusters are non-bleaching fluorescence markers in bio- and medical applications. We show that their fluorescence is an intrinsic property of the Au cluster itself. We find a very intense and sharp fluorescence peak located at λ =739.2 nm (1.68 eV) for Au20 clusters in a Ne matrix held at 6 K. The fluorescence reflects the HOMO-LUMO diabatic bandgap of the cluster. The cluster shows a very rich absorption fine structure reminiscent of well defined molecule-like quantum levels. These levels are resolved since Au20 has only one stable isomer (tetrahedral), therefore our sample is mono-disperse in cluster size and conformation. Density-functional theory (DFT) and time-dependent DFT calculations clarify the nature of optical absorptionand predict both main absorption peaks and intrinsic fluorescence in good agreement with experiment.

    We present recently published results [A. Adare, et al., arxiv:arXiv:1509.04657] on fully reconstructed R=0.3 anti-kt jets measured in p+p and d+Au collisions at 200 GeV center-of-mass energy. The jet yields for four centrality classes along with the p+p reference are presented, as well as both the minimum bias RdAu and centrality dependent RdAu and RCP. We find that while the minimum bias RdA is consistent with unity, providing a strong constraint on models including cold-nuclear-matter effects or energy loss in small systems, the centrality dependent RdAu show a striking variation which presents a challenge to models attempting to describe the interplay between soft and hard processes in these systems.

    2015-12-15

    Asymmetric nanocrystals have practical significance in nanotechnologies but present fundamental synthetic challenges. Thiol ligands have proven effective in breaking the symmetric growth of metallic nanocrystals but their exact roles in the synthesis remain elusive. Here, we synthesized an unprecedented Au nanorod-Au nanoparticle (AuNR-AuNP) dimer structure with the assistance of a thiol ligand. On the basis of our experimental observations, we unraveled for the first time that the thiol could cause an inhomogeneous distribution of surface strains on the seed crystals as well as a modulated reduction rate of metal precursors, which jointly induced the asymmetric growth of monometallic dimers. © 2015 American Chemical Society.

Derrière cette approche se profilent les questions de savoir en quoi peut bien vouloir consister de produire des documents et d’archiver des documents, autant d’opérations à l’issue desquelles les historiens opèrent, et qui cependant ne s’imposent pas d’emblée. À l’analyse de la configuration archivistique de l’Algérie ottomane, j’explorerai ces questions en présentant deux axes de recherches qui m’ont mobilisée. D’une part en interrogeant les effets de l’histoire (coloniale de ces archives sur le sens de leur contenu. D’autre part en présentant les résultats d’une recherche collective autour des conditions de production d’un type de source classique pour les ottomanistes, les registres de cadis.On the Archives of Ottoman Algeria. Archival documentation of Ottoman Algeria is, in general, somewhat scarce, which leads one to reflect upon historians’ practice in such conditions – not by seeking elsewhere what is not supplied in these archives, but rather by examining more closely the sense and social uses of that which does exist. It is henceforth a question of understanding production conditions with regard to their contents and to interpellate them as so many isolated contexts and articulations from

  15. Enantioselective separation on chiral Au nanoparticles.

    The surfaces of chemically synthesized Au nanoparticles have been modified with d- or l-cysteine to render them chiral and enantioselective for adsorption of chiral molecules. Their enantioselective interaction with chiral compounds has been probed by optical rotation measurements during exposure to enantiomerically pure and racemic propylene oxide. The ability of optical rotation to detect enantiospecific adsorption arises from the fact that the specific rotation of polarized light by (R)- and (S)-propylene oxide is enhanced by interaction with Au nanoparticles. This effect is related to previous observations of enhanced circular dichroism by Au nanoparticles modified by chiral adsorbates. More importantly, chiral Au nanoparticles modified with either d- or l-cysteine selectively adsorb one enantiomer of propylene oxide from a solution of racemic propylene oxide, thus leaving an enantiomeric excess in the solution phase. Au nanoparticles modified with l-cysteine (d-cysteine) selectively adsorb the (R)-propylene oxide ((S)-propylene oxide). A simple model has been developed that allows extraction of the enantiospecific equilibrium constants for (R)- and (S)-propylene oxide adsorption on the chiral Au nanoparticles.

  17. Systematic Measurements of Identified Particle Spectra in pp, d+Au and Au+Au Collisions from STAR

    2009-04-11

    Identified charged particle spectra of {pi}{sup {+-}}, K{sup {+-}}, p and {bar p} at mid-rapidity (|y| < 0.1) measured by the dE/dx method in the STAR-TPC are reported for pp and d + Au collisions at {radical}s{sub NN} = 200 GeV and for Au + Au collisions at 62.4 GeV, 130 GeV, and 200 GeV. Average transverse momenta, total particle production, particle yield ratios, strangeness and baryon production rates are investigated as a function of the collision system and centrality. The transverse momentum spectra are found to be flatter for heavy particles than for light particles in all collision systems; the effect is more prominent for more central collisions. The extracted average transverse momentum of each particle species follows a trend determined by the total charged particle multiplicity density. The Bjorken energy density estimate is at least several GeV/fm{sub 3} for a formation time less than 1 fm/c. A significantly larger net-baryon density and a stronger increase of the net-baryon density with centrality are found in Au + Au collisions at 62.4 GeV than at the two higher energies. Antibaryon production relative to total particle multiplicity is found to be constant over centrality, but increases with the collision energy. Strangeness production relative to total particle multiplicity is similar at the three measured RHIC energies. Relative strangeness production increases quickly with centrality in peripheral Au + Au collisions, to a value about 50% above the pp value, and remains rather constant in more central collisions. Bulk freeze-out properties are extracted from thermal equilibrium model and hydrodynamics-motivated blast-wave model fits to the data. Resonance decays are found to have little effect on the extracted kinetic freeze-out parameters due to the transverse momentum range of our measurements. The extracted chemical freeze-out temperature is constant, independent of collision system or centrality; its value is close to the predicted phase

    Full Text Available Dans les vallées de l'intérieur de la Provence, de grandes accumulations de tufs et de travertins sont liées aux sources karstiques importantes. En rapport avec l'évolution géomorphologique, les travertins anciens forment des balcons et des terrasses. La période récente de grande construction travertineuse débute souvent au Préboréal et se généralise dans l'Atlantique. Au cours du Néolithique final, cette sédimentation décroît en fonction de la détérioration climatique et de la déforestation liée à la pression anthropique. Cependant quelques barrages (dômes stromatolitiques et marais, avec dépôts de tourbes, persistent jusqu'à l'âge historique. Dans le Centre-Var, les dépôts de tufs restent actifs dans quelques sites refuges, dans les hautes vallées forestières, proches des sources karstiques, et sur quelques grandes cascades. De plus, le long des rivières, des cascades à tufs sont issues des aménagements de moulins et de canaux d'irrigation.La sédimentation des tufs dépend de nombreux facteurs en interaction, dont :- la minéralisation carbonatée des eaux des sources karstiques,- le régime hydrologique saisonnier,- l'écosystème régional et local (forêts, ripisylves,- le biotope algo-bryophytique.De nos jours, la sédimentation stromatolitique est en situation critique du fait de l'impact de multiples facteurs en rapport avec l'accroissement de l'urbanisation et les changements environnementaux :- pollution, accroissement de la turbidité sur les petits affluents résultant de l'agriculture mécanisée,- diminution drastique des débits dans les saisons de printemps-été, où l'activité algo-bryophytique est la plus favorable, du fait de l'augmentation générale des prélèvements.La période de sécheresse récente (2006-2008 a accentué ces impacts sur les barrages de tufs.

    We report measurements of ϒ meson production in p+p, d+Au, and Au+Au collisions using the STAR detector at RHIC. We compare the ϒ yield to the measured cross section in p+p collisions in order to quantify any modifications of the yield in cold nuclear matter using d+Au data and in hot nuclear matter using Au+Au data separated into three centrality classes. Our p+p measurement is based on three times the statistics of our previous result. We obtain a nuclear modification factor for ϒ(1S+2S+3S) in the rapidity range |y|<1 in d+Au collisions of R{sub dAu}=0.79±0.24(stat.)±0.03(syst.)±0.10(p+p syst.). A comparison with models including shadowing and initial state parton energy loss indicates the presence of additional cold-nuclear matter suppression. Similarly, in the top 10% most-central Au+Au collisions, we measure a nuclear modification factor of R{sub AA}=0.49±0.1(stat.)±0.02(syst.)±0.06(p+psyst.), which is a larger suppression factor than that seen in cold nuclear matter. Our results are consistent with complete suppression of excited-state ϒ mesons in Au+Au collisions. The additional suppression in Au+Au is consistent with the level expected in model calculations that include the presence of a hot, deconfined Quark–Gluon Plasma. However, understanding the suppression seen in d+Au is still needed before any definitive statements about the nature of the suppression in Au+Au can be made.

    The proton beam intensity of a 100-MeV proton linac at the Korea Multi-purpose Accelerator Complex (KOMAC) was measured by an Au activation analysis using {sup 197}Au(p, pn){sup 196}Au and {sup 197}Au(p, p3n){sup 194}Au reactions to determine the accuracy and precision of beam intensity measurement using Gafchromic film dosimetry method. The target, irradiated by 100-MeV protons, was arranged in a stack consisting of Au, Al foils and Pb plates. The yields of produced radio-nuclei in Au foils were obtained by gamma-ray spectroscopy. The FLUKA code was employed to calculate the energy spectrum of protons onto the front surface of Au foils located at three different depth points of the target and also to investigate the condition of incident beam on the target. A good agreement was found between the beam intensity measurements using the activation analysis method at three different depth points of the target. An excellent agreement was also observed between the beam intensity measurements using the Au activation analysis method and the dosimetry method using Gafchromic film.

    Les peuples des Premières nations, inuits et métis qui habitent au Canada sont aux prises avec de profondes disparités en matière de santé par rapport aux Canadiens non autochtones, et ce, dans presque toutes les mesures liées à la santé et au bien-être. Pour faire progresser les services de santé auprès des peuples autochtones, il faut passer à l'action dans tous les ordres de prestation des soins et des politiques en santé. Il est donc essentiel que les leaders et les prestataires des établissements, des systèmes et des installations de santé du Canada comprennent et prennent en main les déterminants de la santé propres aux peuples autochtones, y compris l'héritage du colonialisme et le racisme ancien et actuel. La Commission de vérité et réconciliation du Canada est le point de départ pour réagir de manière positive aux injustices.

    Being able to precisely control the morphologies of noble metallic nanostructures is of essential significance for promoting the surface-enhanced Raman scattering (SERS) effect. Herein, we demonstrate an overgrowth strategy for synthesizing Au @ M (M = Au, Ag, Pd, Pt) core-shell heterogeneous nanocrystals with an orientated structural evolution and highly improved properties by using Au nanorods as seeds. With the same reaction condition system applied, we obtain four well-designed heterostructures with diverse shapes, including Au concave nanocuboids (Au CNs), Au @ Ag crystalizing face central cube nanopeanuts, Au @ Pd porous nanocuboids and Au @ Pt nanotrepangs. Subsequently, the exact overgrowth mechanism of the above heterostructural building blocks is further analysed via the systematic optimiziation of a series of fabrications. Remarkably, the well-defined Au CNs and Au @ Ag nanopeanuts both exhibit highly promoted SERS activity. We expect to be able to supply a facile strategy for the fabrication of multimetallic heterogeneous nanostructures, exploring the high SERS effect and catalytic activities.

    Neutral pions have been measured in 3He+Au collisions at √{sNN } = 200 GeV up to 20 GeV/c in the RHIC Year-2014 run. The nuclear modification factor RAA was measured and compared with that from d+Au collisions. The integrated RAA as a function of Npart was calculated for d+Au, 3He+Au and Au+Au collisions at √{sNN } = 200 GeV, and found to converge for Npart > 12, while a clear system ordering RdAu >RHeAu >RAuAu was observed for Npart > 12. The fractional momentum loss for the most central 3He+Au collisions was also estimated.

    In connection to the decision of installing the INDRA detector by the SIS synchrocyclotron at GSI (Darmstadt, Germany) the report presents the tasks taken into account by the LPC-Caen. These refer to the detector displacement and (mechanical) installation at GSI, the tests before beam (i.e. electronics acquisition software, detectors, etc.) as well as the data acquisition and processing. The physical pro-arguments mention the possibility of disposing of heavy ion beams in a range from 50 MeV to several GeV/nucleon so extending the study of multifragmentation done at GANIL between 30 and 90 MeV/nucleon. More specific, the scientific program of INDRA at GSI inserts studies between those done at around Fermi energy, were the reaction mechanisms are of type of deep inelastic scattering/incomplete fusion, and the studies in the relativistic energy domain where the individual properties of nucleons and transparency of nuclear matter implies mechanisms of the participant-spectator type (fire-ball creation). Also mentioned as fields of extensive studies are: the multifragmentation and its fundamental relation with the nuclear matter equation of state, the role of reaction dynamics in the appearance of collective effects of the radial flow type and its relations with the nuclear compressibility and phase transitions and the thermodynamics of nuclear matter. It appeared that the heavy systems Xe + Sn and Au + Au are the best compromise for the different topics to be approached. The bombarding energies extend from 50 to 150 MeV/nucleon. The report ends with the table giving for six heavy systems (Xe + Sn, Au + Au, C + Au, Ar + Au and P + Au) the required bombarding energies 15 refs.

    New patients are a particularly vulnerable population because they are at high risk of missing a subsequent visit or dropping out of care completely. However, few data exist on what new patients value in the beginning of a relationship with a new provider. Persons with HIV infection may be an ideal population to study the drivers of a positive initial patient-provider relationship, as it is a chronic and serious condition that requires a reliable, ongoing relationship with a provider. Informed by patients' real experiences, this study aims to identify what patients see as the most critical elements for building trust and rapport from the outset. We conducted longitudinal, in-person interviews with 21 patients new to the HIV clinic at the Michael E. DeBakey Veterans Affairs Medical Center in Houston, Texas, from August 2013 to March 2015. Patients were interviewed across three time points: once before their first provider visit, a second time within two weeks after the first visit, and a third time at 6 to 12 months after the first provider visit. We conducted 61 h of patient interviews. The mean age was 53 years; 52% were non-Hispanic white, 23% were non-Hispanic black and 19% were Hispanic. Patients described significant anxiety and vulnerability not just from HIV itself, but also in starting a relationship as a new patient to a new provider. Our analysis of these experiences revealed five actions providers can take to reduce their patients' anxiety and build trust early in the first visit: 1) provide reassurance to patients, 2) tell patients it's okay to ask questions, 3) show patients their lab results and explain what they mean, 4) avoid language and behaviors that are judgmental of patients, and 5) ask patients what they want [i.e., treatment goals and preferences]. Our study incorporates direct input from patients and highlights the unique psychological challenges that patients face in seeking care from a new provider. The actionable opportunities cited by

    The cyanidation process has been used commercially for the past 100 years, there are ores that are not amenable to treatment by cyanide. Interest in alternative lixiviants, such as thiourea, halogens, thiosulfate and malononitrile, has been revived as a result of a major increase in gold price, which has stimulated new developments in extraction technology, combined with environmental concern. The Au extraction process using the thiourea solvent has many advantages over the cyanidation process, including higher leaching rates, faster extraction time and less than toxicity. The purpose of this study was investigated to the extraction characteristic of Au-Ag from two different Au concentrate (sulfuric acid washing and roasting) under various experiment conditions (thiourea concentration, pH of solvent, temperature) by thiourea solvent. The result of extraction experiment showed that the Au-Ag extraction was a fast extraction process, reaching equilibrium (maximum extraction rate) within 30 min. The Au-Ag extraction rate was higher in the roasted concentrate than in the sulfuric acid washing. The higher the Au-Ag extraction rate (Au - 70.87%, Ag - 98.12%) from roasted concentrate was found when the more concentration of thiourea increased, pH decreased and extraction temperature increased. This study informs extraction method basic knowledge when thiourea was a possibility to eco-/economic resources of Au-Ag utilization studies including the hydrometallurgy.

    Highlights: • An inversed Au/ZnO nanostructure was fabricated with ZnO loaded onto Au. • The Au/ZnO nanocomposites showed enhanced properties in visible-light photocatalysis. • The SPR effect of Au was considered important for visible-light photocatalysis. - Abstract: In this paper, we fabricate Au/ZnO nanostructure with smaller ZnO nanoparticles loaded onto bigger gold nanoparticles via combining seed-mediated method and sol-gel method. The obtained Au/ZnO nanocomposites exhibit excellent properties in photocatalysis process like methyl orange (MO) degradation and oxidative conversion of methanol into formaldehyde under visible light irradiation. The enhanced properties were ascribed to the surface plasmon resonance (SPR) effect of Au nanoparticles, which could contribute to the separation of photo-excited electrons and holes and facilitate the process of absorbing visible light. This paper contributes to the emergence of multi-functional nanocomposites with possible applications in visible-light driven photocatalysts and makes the Au/ZnO photocatalyst an exceptional choice for practical applications such as environmental purification of organic pollutants in aqueous solution and the synthesis of fine chemicals and intermediates.

    One of the best methods for producing bulk homogeneous (composition) supported bimetallic AuPd clusters involves the immobilization of a protected Au seed followed by the addition of Pd. This paper investigates the importance of this gold seed in controlling the resulting bimetallic AuPd clusters structures, sizes and catalytic activities by investigating three different gold seeds. Uniform Au-Pd alloy were obtained when a steric/electrostatic protecting group, poly(vinyl alcohol) (PVA), was used to form the gold clusters on activated carbon (AC). In contrast Au/AC precursors prepared using Au nanoparticles with only electrostatic stabilization (tetrakis(hydroxypropyl)phosphonium chloride (THPC)), or no stabilization (magnetron sputtering) produced inhomogeneous alloys and segregation of the gold and palladium. The uniform alloyed catalyst (Pd{at}Au{sub PVA}/AC) is the most active and selective catalyst, while the inhomogenous catalysts are less active and selective. Further study of the PVA protected Au clusters revealed that the amount of PVA used is also critical for the preparation of uniform alloyed catalyst, their stability, and their catalytic activity.

L’étude menée est la première étude ex post, couvrant la période de 2008–2013, relative aux impacts financiers respectifs des sociétés cotonnières et des paysans, chaque catégorie étant prise globalement. L’étude est originale en tenant compte de la transformation génétique imparfaite des variétés utilisées. L’étude évalue les impacts financiers d’une situation réelle d’utilisation du coton-Bt par rapport à une situation de référence sans recours au coton-Bt. L’évaluation est faite aussi par rapport au scénario anticipé lors de la décision d’adoption et dont l’hypothèse d’un gain de rendement au champ de 30 % n’a pas été confirmée. L’évaluation est réalisée par la méthode de budget partiel avec des calculs de sensibilité à trois critères, industriel, commercial et du prix mondial. Pour les paysans, l’impact financier est positif, mais le ratio de rentabilité du surcoût des semences est à peine acceptable. Pour les sociétés cotonnières, l’impact financier est modeste et est devenu négatif à mesure que le prix mondial du coton est descendu de son record historique, en raison du manque à gagner en quantité de fibre produite, de la réduction en longueur du coton fibre et de l’application d’un malus à la vente à l’exportation. L’image d’un pays fournissant habituellement un coton de qualité est négativement affectée. L’adoption du coton-Bt au Burkina Faso constitue un cas rare d’évolution technologique induisant une divergence d’impacts entre les deux catégories d’acteurs avec une incidence négative potentielle sur le financement de la recherche pour poursuivre le progrès technique.

    Alloys and intermetallic compounds of Au with the 3d transition metals Fe, Co, and Ni are nonequilibrium phases that have many useful potential applications as catalytic, magnetic, optic, and multifunctional magneto-optic materials. However, the atomically ordered Au-M (M = Fe, Co, Ni) intermetallics are particularly elusive from a synthetic standpoint. Here we report the low-temperature solution synthesis of the L12 (Cu3Au-type) intermetallic compounds Au3Fe, Au3Co, and Au3Ni using n-butyllithium as a reducing agent. Reaction pathway studies for the Au3Co system indicate that Au nucleates first, followed by Co incorporation to form the intermetallic. The nonequilibrium intermetallic nanocrystals have been characterized by powder XRD, TEM, EDS, selected area electron diffraction, and nanobeam electron diffraction, which collectively confirm the compositions and superlattice structures.

  19. Jets and dijets in Au+Au and p+p collisions at RHIC

    Hardtke, D.; STAR Collaboration

    2002-12-09

    Recent data from RHIC suggest novel nuclear effects in the production of high p{sub T} hadrons. We present results from the STAR detector on high p{sub T} angular correlations in Au+Au and p+p collisions at {radical}S = 200 GeV/c. These two-particle angular correlation measurements verify the presence of a partonic hard scattering and fragmentation component at high p{sub T} in both central and peripheral Au+Au collisions. When triggering on a leading hadron with p{sub T}>4 GeV, we observe a quantitative agreement between the jet cone properties in p+p and all centralities of Au+Au collisions. This quantitative agreement indicates that nearly all hadrons with p{sub T}>4 GeV/c come from jet fragmentation and that jet fragmentation properties are not substantially modified in Au+Au collisions. STAR has also measured the strength of back-to-back high p{sub T} charged hadron correlations, and observes a small suppression of the back-to-back correlation strength in peripheral collisions, and a nearly complete disappearance o f back-to-back correlations in central Au+Au events. These phenomena, together with the observed strong suppression of inclusive yields and large value of elliptic flow at high p{sub T}, are consistent with a model where high p{sub T} hadrons come from partons created near the surface of the collision region, and where partons that originate or propagate towards the center of the collision region are substantially slowed or completely absorbed.

    Au/Cu bilayers with different Au:Cu concentrations (25:75, 50:50 and 75:25 at.%) were deposited on Si(100) substrates by thermal evaporation. The thicknesses of all Au/Cu bilayers were 150 nm. The alloys were prepared by thermal diffusion into a vacuum oven with argon atmosphere at 690 K during 1 h. X-ray diffraction analysis revealed different phases of AuCu and CuSi alloys in the samples after annealing process. CuSi alloys were mainly obtained for 25:75 at.% samples, meanwhile the AuCuII phase dominates for samples prepared with 50:50 at.%. Additionally, the Au:Cu alloys with 75:25 at.%, produce Au{sub 2}Cu{sub 3} and Au{sub 3}Cu phases. The formed alloys were characterized by scanning electron microscopy (SEM), atomic force microscopy (AFM), transmission electron microscopy (TEM) and energy dispersive spectroscopy (EDS) to study the morphology and the elemental concentration of the formed alloys. - Highlights: • AuCu/Si alloy thin films were prepared by thermal diffusion. • Alloys prepared with 50 at.% of Au produce the AuCuII phase. • Alloys prepared with 75 at.% of Au produce Au{sub 3}Cu and Au{sub 2}Cu{sub 3} phases. • All alloys present diffusion of Si and Cu through the CuSi alloy formation.

    Full Text Available La conflictualité conjugale analysée avec le concept de genre, et pas seulement en vue de vérifier l’application ou non du droit matrimonial par les juges d’église, rejoint le courant davantage socio-anthropologique que juridique de l’histoire du couple en Occident au Moyen Âge. Un souffle d’optimisme historiographique provient de travaux récents, dans un champ d’étude où l’on tardait encore à apprécier la capacité des femmes à ne pas subir de tristes situations conjugales, faites de violence, de misère sentimentale et sexuelle. Il n’empêche que le conflit, au moment de sa création, son récit devant le juge, les attentes des litigants quant à sa résolution obéissent à un rapport de force entre genres clairement distingués entre eux jusque dans le choix des normes, des arguments invoqués, de la rhétorique judiciaire déployée dans les procès. Même lorsque le couple agit par collusion, le dialogue avec le juge obéit aussi à des différences de genre.The analysis of matrimonial conflicts using the concept of gender, which goes beyond the verification of whether judges applied or not canonical law, draws more on socio-anthropological trends in the history of the married couple in the middle ages than on legal trends. The new historiographical optimism present in recent works testifies to how women were able to refuse some matrimonial situations despite the existence of domestic violence, forced sexual abstinence (impotence and limited sentimental exchanges with their husbands. Nonetheless, this article highlights how gender determined the nature of every matrimonial conflict and its description before the judge. Gender underwrote as well the expectations litigants had in using lawsuits, given the power relationship between the sexes, even when wives and husbands sought  a judicial separation by mutual agreement.

    Lactobacillus para paracasei are used commonly as functional food and probiotic substances. In this work Au nanoparticles self-assembled films were used for Lactobacillus para paracasei determination at five different concentrations. Functionalized substrates were immersed in a colloidal solution for one and a half hour at room temperature and dried at room temperature during four hours. After that, drops of Lactobacillus para paracasei in aqueous solution were put into the Au nanoparticles film and let dry at room temperature for another two hours. Infrared spectroscopy in attenuated total reflectance sampling mode was used to observe generation peaks due to substrate silanization, enhancement of Si-O band intensity due to the Au colloids added to silanized substrate and also to observe the enhancement of Lactobacillus para paracasei infrared intensity of the characteristic frequencies at 1650, 1534 and 1450 cm{sup -1} due to surface enhancement infrared absorption.

    2016-04-01

    The PHENIX experiment at the Relativistic Heavy Ion Collider has performed a comprehensive set of measurements in d + Au collisions. Observables in d + Au collisions were originally conceived as a control experiment where no quark-gluon plasma is formed and one could isolate so-called cold nuclear matter effects, including nuclear modified parton distributions and parton multiple scattering. However, recent data from the PHENIX experiment in d + Au, in conjunction with new p + Pb results at the Large Hadron Collider, give strong evidence for a very different picture. We present new results that hint at the formation of a small quark-gluon plasma, that though short lived, leaves a fingerprint of evidence on final state observables. These new results will be discussed in the context of competing theoretical interpretations.

    This paper describes the Neogene lava-sediment mingling from the Abu Treifiya Basin, Cairo-Suez district, Egypt. The lava-sediment interactions as peperites have been identified for the first time at the study area and can be used as paleoenvironmental indicators. The identification of peperite reflects contemporaneous time relationship between volcanism and sedimentation and this finding is of primary importance to address the evolutional reconstruction of the Abu Treifiya Basin. Characterization of the facies architecture and textural framework of peperites was carried out through detailed description and interpretation of their outcrops. The peperites and sedimentary rocks are up to 350 m thick and form a distinct stratigraphic framework of diverse lithology that is widespread over several kilometers at the study area. Lateral and vertical facies of the peperites vary from sediment intercalated with the extrusive/intrusive basaltic rocks forming peperitic breccias to lava-sediment contacts at a large to small scales, respectively. Peperites encompass five main facies types ascribed to: (i) carbonate sediments-hosted fluidal and blocky peperites, (ii) lava flow-hosted blocky peperites, (iii) volcaniclastics-hosted fluidal and blocky peperites, (iv) sandstone/siltstone rocks-hosted blocky peperites, and (iv) debris-flows-hosted blocky peperites. Soft sediment deformation structures, vesiculated sediments, sediments filled-vesicles, and fractures in lava flows indicate that lava flows mingled with unconsolidated wet sediments. All the peperites in this study could be described as blocky or fluidal, but mixtures of different clast shapes occur regardless of the host sediment. The presence of fluidal and blocky juvenile clasts elucidates different eruptive styles, reflecting a ductile and brittle fragmentation. The gradual variation from fluidal to blocky peperite texture, producing the vertical grading is affected by influencing factors, e.g., the viscosity, magma

    Star-shaped mesotructures are formed when an aqueous suspension of Au nanorice particles, which consist of prolate hematite cores and a thin Au shell, is subjected to an electric current. The nanorice particles assemble to form hyperbranched micrometer-scale mesostars. To our knowledge, this is the first reported observation of nanoparticle assembly into larger ordered structures under the influence of an electrochemical process (H(2)O electrolysis). The assembly is accompanied by significant modifications in the morphology, dimensions, chemical composition, crystallographic structure, and optical properties of the constituent nanoparticles.

  9. On the Stark broadening in the Au I and Au II spectra from a helium plasma

    2009-03-01

    The Stark FWHM (Full-Width at Half of the Maximal line intensity, W) of 5 neutral and 26 singly ionized gold (Au I and Au II, respectively) spectral lines have been measured in laboratory helium plasma at approximately 16,600 K electron temperature and 7.4 × 10 22 m - 3 electron density. Five Au I and ten Au II W values are reported for the first time. The Au II W values are compared with recent theoretical data, calculated based on a modified semi-empirical approach, and also with existing experimental W values. Our normalized Stark widths are six times higher than those measured in a laser-produced plasma. Possible explanation of this is recommended here. An agreement (within the accuracy of the experiment and uncertainties of the theoretical approach used) with the recently calculated W data was found in the 6p-7s Au II transition. The calculated hyperfine splitting for the five Au II lines in the 6s-6p transition is also presented. At the stated helium plasma conditions, Stark broadening has been found to be the dominant mechanism in the Au I and Au II line shape formation. A modified version of the linear low-pressure pulsed arc was used as a plasma source operated in helium, with gold atoms as impurities evaporated from the thin gold cylindrical plates located in the homogeneous part of the discharge, providing conditions free of self-absorption. This plasma source ensures good conditions for generation of excited gold ions due to Penning and charge exchange effects.

    Although many SINE families have been identified in the animal kingdom, only a few SINE families have been identified in plants, and their distribution is somewhat limited. The Au SINE (Au) has been found discontinuously in basal angiosperms, monocots, and eudicots. In this study, we examined the presence of the Au in gymnosperms and ferns by PCR using internal primers for Au. As a result, we found Au in a gymnosperm species, Ephedra ciliata. Therefore, Au was supposed to be present in the common ancestor of angiosperms and gymnosperms. The Au in E. ciliate was 15 bp shorter than the consensus sequence, which is similar to the Au SINE found in Glycine. However, the 3'end of the Au found in E. ciliate was more similar to the 3'end of the Medicago-type Au than that of the Glycine-type Au. A phylogenetic tree indicated that the Au sequence from E. ciliate is more closely related to the sequence found in Glycine than that found in Medicago/Lotus. These results indicated that Au were present in both angiosperms and gymnosperms.

    We present transverse momentum distributions of charged hadrons produced in Au+Au collisions at {radical}S{sub NN} = 200 GeV. The evolution of the spectra for transverse momenta p{sub T} from 0.25 to 5 GeV/C is studied as a function of collision centrality. We find a significant change of the spectral shape between proton-antiproton and peripheral Au+Au collisions. When comparing peripheral to central Au+Au collisions, we find that the yields at the highest p{sub T} exhibit approximate scaling with the number of participating nucleons, rather than scaling with the number of binary collisions.

Cette méthode permet de modéliser les revenus agricoles en fonction des variables climatiques, édaphiques, hydrologiques et socio-économiques. Plusieurs modèles économétriques ont été testés sur la base des données primaires de la campagne agricole 2002-2003. Ces modèles ont permis d’établir d’une part la relation qui existe entre le revenu agricole et les variables climatiques (température et précipitation et d’autre part, d’analyser la sensibilité des revenus agricoles par rapport à ces variables climatiques. Des simulations ont été faites sur la base des prévisions du groupe d’experts intergouvernemental sur l’évolution du climat (GIEC. Les résultats de l’étude ont montré que la relation entre le revenu et le climat est non linéaire. L’impact marginal de la température sur le revenu agricole est de -19,9 dollars US par hectare tandis que celui de la précipitation est de +2,7 dollars US par hectare. L’analyse des élasticités montre que l’agriculture est très sensible à la précipitation au Burkina. L’augmentation des précipitations de 1% entraine une hausse des revenus agricoles de 14,7%. Cependant, une augmentation des températures de 1% entraine une baisse des revenus agricoles de 3,6%. Les analyses de sensibilité ont montré que les paysans perdront 93% de leurs revenus suite à une augmentation de la température de 5°C. Ils perdront tout leur revenu suite à une diminution des précipitations de 14% (ceteris paribus. Du fait des conditions climatiques déjà difficiles, les scenarii de diminution des précipitations ou/et d’augmentation des températures sont très dommageables à l’agriculture au Burkina. Par ailleurs, l’étude a montré que la pratique de l’irrigation et l’accès à la vulgarisation ont un effet

    The unique properties of gold especially in low temperature CO oxidation have been ascribed to a combination of various effects. In particular, particle sizes below a few nm and specific particle-support interactions have been shown to play important roles. On the contrary, recent reports revealed that monolithic nanoporous gold (npAu) prepared by leaching a less noble metal, such as Ag, out of the corresponding alloy can also exhibit remarkably high catalytic activity for CO oxidation, even though no support is present. Therefore, it was claimed to be a pure and unsupported gold catalyst. We investigated npAu with respect to its morphology, surface composition and catalytic properties. In particular, we studied the reaction kinetics for low temperature CO oxidation in detail taking mass transport limitation due to the porous structure of the material into account. Our results reveal that Ag, even if removed almost completely from the bulk, segregates to the surface resulting in surface concentrations of up to 10 at%. Our data suggest that this Ag plays a significant role in activation of molecular oxygen. Therefore, npAu should be considered as a bimetallic catalyst rather than a pure Au catalyst.

In jüngster Zeit werden insbesondere moderne didaktisch-methodische Konzepte näher diskutiert und praktiziert. So finden sich etwa die Stichwörter Handlungsorientierter Unterricht und Offener Unterricht in der fachdidaktischen Diskussion wieder. Eine wesentlich aktuellere Form stellt das außerschulische Lernen dar. Ein modernes pädagogisches Verständnis sieht den Unterricht heute nicht mehr als ausschließliche Tätigkeit des Lehrers an, sondern als Aktivität der Lernenden. Außerschulisches Lernen beschreibt die originale Begegnung im Unterricht außerhalb des Klassenzimmers. An außerschulischen Lernorten findet eine unmittelbare AuseinanderSetzung des Lernenden mit seiner räumlichen Umgebung statt. Charakteristisch sind hierbei vor allem die aktive(Mit-)Gestaltung sowie die eigenständige Wahrnehmung mehrperspektivischer Bildungsinhalte d...

    Full Text Available Important effects of petroleum reservoir stratification upon chemical enhanced oil recovery processes have been modelled using systems containing layers of two different permeabilities. Experimentally, visual models composed of glass bead packings have been exploited and miscible matched-density displacements performed. The results show a strong sensitivity to fluid mobility ratio. Flow pattern observation and mathematical analysis have shown that complex viscous crossflow processes are very influential. We present a non-empirical mathematical model for dual layer systems. Our calculation of crossflow effects using this analytical method compares favourably with experimental results from varions sources. Finally, we show how to apply this model to multilayer cross-sectional and three-dimensional problems. Des effets majeurs de la stratification de réservoirs pétroliers sur les procédés chimiques de récupération assistée du pétrole ont été modélisés au moyen de systèmes comprenant des couches à deux perméabilités différentes. Pour l'approche expérimentale, nous avons eu recours à des modèles d'observation composés de billes de verre où des déplacements de fluides miscibles de densités ajustées ont été réalisés. Les résultats indiquent une forte sensibilité au rapport de mobilité des fluides. L'observation du schéma d'écoulement et son analyse mathématique ont montré que des phénomènes d'écoulement visqueux interbancs ont une très grande influence. Nous présentons un modèle mathématique non empirique de systèmes à double couche. Nos calculs des effets des écoulements transversaux avec des méthodes analytiques sont bien vérifiés par les résultats expérimentaux provenant de sources diverses. Nous montrons enfin comment appliquer ce modèle à des problèmes à plusieurs bancs avec échanges entre couches et à trois dimensions.

    Nanocomposite materials of the Au nanoparticles (Au/PDDA-G) and the bimetallic PtAu nanoparticles on poly-(diallyldimethylammonium chloride) (PDDA)-modified graphene sheets (PtAu/PDDA-G) were prepared with hydrothermal method at 90 °C for 24 h. The composite materials Au/PDDA-G and PtAu/PDDA-G were evaluated by transmission electron microscopy (TEM), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), and thermogravimetric analysis (TGA) for exploring the structural characterization for the electrochemical catalysis. According to TEM results, the diameter of Au and bimetallic PtAu nanoparticles is about 20-50 and 5-10 nm, respectively. X-ray diffraction (XRD) results indicate that both of PtAu and Au nanoparticles exhibit the crystalline plane of (111), (200), (210), and (311). Furthermore, XRD data also show the 2°-3° difference between pristine graphene sheets and the PDDA-modified graphene sheets. For the catalytic activity tests of Au/PDDA-G and PtAu/PDDA-G, the mixture of 0.5 M aqueous H2SO4 and 0.5 M aqueous formic acid was used as model to evaluate the electrochemical characterizations. The catalytic activities of the novel bimetallic PtAu/graphene electrocatalyst would be anticipated to be superior to the previous electrocatalyst of the cubic Pt/graphene.

    Full Text Available This article is the result of a qualitative inquiry started on 2001, whose principal interest was the study of territorially-based process of social organization and mobilization. From the eighties, is possible to find two main approaches in the study of political bonds in the underclass: those which suppose the perfect matching between public demands and individual reasons for political involving and those which sustain an absolute alienation between those demands and participants’ individual interests. From the study of two life stories, we observe that political participation leaves traces on the way how subjects articulate their experiences. That is to say, in the way how they give sense to their past and present attitudes and perceptions and in the manner they anticipate their future. This point of view let us overcome the interrogation about reasons that explain political mobilization and its related reifying interpretations about construction of the political rapports.

    Directed flow of deuterons, tritons, $^3$He, and $^4$He is studied in Au+Au collisions at a beam momentum of about 10.8 $A$ GeV/c. Flow of all particles is analyzed as a function of transverse momentum for different centralities of the collision. The directed flow signal, $v_1(p_t)$, is found to increase with particle mass. This mass dependence is strongest in the projectile rapidity region.

    Density functional theory calculations have been performed to study the experimentally synthesized Au30S(SR)18 and two related Au30(SR)18 and Au30S2(SR)18 clusters. The patterns of thiolate ligands on the gold cores for the three thiolate-protected Au30 nanoclusters are on the basis of the "divide and protect" concept. A novel extended protecting motif with u3-S, S(Au2(SR)2)2AuSR, is discovered, which is termed the tridentate protecting motif. The Au cores of Au30S(SR)18, Au30(SR)18 and Au30S2(SR)18 clusters are Au17, Au20 and Au14, respectively. The superatom-network (SAN) model and the superatom complex (SAC) model are used to explain the chemical bonding patterns, which are verified by chemical bonding analysis based on the adaptive natural density partitioning (AdNDP) method and aromatic analysis on the basis of the nucleus-independent chemical shift (NICS) method. The Au17 core of the Au30S(SR)18 cluster can be viewed as a SAN of one Au6 superatom and four Au4 superatoms. The shape of the Au6 core is identical to that revealed in the recently synthesized Au18(SR)14 cluster. The Au20 core of the Au30(SR)18 cluster can be viewed as a SAN of two Au6 superatoms and four Au4 superatoms. The Au14 core of Au30S2(SR)18 can be regarded as a SAN of two pairs of two vertex-sharing Au4 superatoms. Meanwhile, the Au14 core is an 8e-superatom with 1S(2)1P(6) configuration. Our work may aid understanding and give new insights into the chemical synthesis of thiolate-protected Au clusters.

    The self-assembled fabrication of nanostructure, a dreaming approach in the area of fabrication engineering, is the ultimate goal of this research. A finding was proved through previous research that the size of the self-assembled gold nanoparticles could be controlled with the mole ratio between AuCl{sub 4}{sup -} and thiol. In this study, the moles of Au were fixed, only the moles of thiol were adjusted. Five different mole ratios of Au/S with their effect on size uniformity were investigated. The mole ratios were 1:1/16, 1:1/8, 1:1, 1:8, 1:16, respectively. The size distributions of the gold nanoparticles were analyzed by Mac-View analysis software. HR-TEM was used to derive images of self-assembled gold nanoparticles. The result reached was also the higher the mole ratio between AuCl{sub 4}{sup -} and thiol the bigger the self-assembled gold nanoparticles. Under the condition of moles of Au fixed, the most homogeneous nanoparticles in size distribution derived with the mole ratio of 1:1/8 between AuCl{sub 4}{sup -} and thiol. The obtained nanoparticles could be used, for example, in uniform surface nanofabrication, leading to the fabrication of ordered array of quantum dots.

    We studied the feasibility of using vacuum ultraviolet (VUV) treatment as a surface improvement technique with Au-Au flip-chip bonding. For fine-pitch electrical interconnections in three-dimensional (3D) stack applications, robust and reliable bonding is desirable; in this case, surface modification treatment is needed before the bonding process. A VUV surface treatment was used to remove organic contaminants. Samples of electroplated Au pads were examined by X-ray photoelectron spectroscopy (XPS) to evaluate the chemical composition of the Au surfaces. The XPS results revealed that the carbon-based contaminants on the surface were removed by the VUV treatment. The shear strength of the bonded sample was also improved. The average shear strength of a bump with VUV treatment is 1.6 times larger than that of a bump without VUV treatment. Cross-sectional scanning electron microscopy (SEM) images of the bonded samples confirmed the absence of voids and cracks. The results show that VUV treatment has clear effects on Au-Au flip-chip bonding.

    Introduction Le diabète représente la première cause de mortalité par insuffisance rénale au Maroc. Sa prévalence selon l'Enquête Nationale sur la Population et la Santé Familiale de 2011 est de 3,3% [1]. Le but de ce travail est de déterminer la prévalence et d’étudier le profil clinique des diabétiques en hémodialyse chronique au Maroc. Méthodes Il s'agit d'une étude transversale multicentrique incluant 2066 hémodialysés chroniques dans les 39 centres d'hémodialyse de quatre régions marocaines. Résultats La prévalence du diabète en hémodialyse est 21,6%. L’âge moyen 59±13,2 ans (26-87). Le sex-ratio est de 1,9. L'IMC moyen est de 24,5 ± 4,4 kg/m2 (15-41). 42 patients sont porteurs d′une hépatite virale. La durée moyenne en HD est 39,3± 67 mois. 57% des patients gardent une diurèse résiduelle versus 43% chez les non diabétiques. Par rapport à ces derniers, nous avons noté plus d'HTA (64% versus 45%), plus de complications cardiovasculaires (23% versus 12%), un âge plus avancé à l'initiation de l'hémodialyse (55,5 versus 47 ans) et un taux de FAV proximales plus important. Conclusion La prévalence des diabétiques en hémodialyse est relativement élevée au Maroc sans tenir compte des patients qui ne bénéficient pas d’épuration extra-rénale pour des raisons socio-économiques. Le taux élevé de mortalité est imputable au retard et/ou à l'absence de la prise en charge néphrologique des diabétiques. Dans nos régions où le système sanitaire dispose de faible moyen, l'accent doit être mis sur le dépistage précoce de la néphropathie chez le diabétique. PMID:25374630

    The ternary Eu(Au/In)2 (EuAu(0.46)In(1.54(2))) (I), EuAu4(Au/In)2 (EuAu(4+x)In(2-x) with x = 0.75(2) (II), 0.93(2), and 1.03(2)), and Eu5Au16(Au/In)6 (Eu5Au(17.29)In(4.71(3))) (III) have been synthesized, and their structures were characterized by single-crystal X-ray diffraction. I and II crystallize with the CeCu2-type (Pearson Symbol oI12; Imma; Z = 4; a = 4.9018(4) Å; b = 7.8237(5) Å; c = 8.4457(5) Å) and the YbAl4Mo2-type (tI14; I4/mmm; Z = 2; a = 7.1612(7) Å; c = 5.5268(7) Å) and exhibit significant Au/In disorder. I is composed of an Au/In-mixed diamond-related host lattice encapsulating Eu atoms, while the structure of II features ribbons of distorted, squared Au8 prisms enclosing Eu, Au, and In atoms. Combination of these structural motifs leads to a new structure type as observed for Eu5Au16(Au/In)6 (Eu5Au(17.29)In(4.71(3))) (oS108; Cmcm; Z = 4; a = 7.2283(4) Å; b = 9.0499(6) Å; c = 34.619(2) Å), which formally represents a one-dimensional intergrowth of the series EuAu2-"EuAu4In2". The site preferences of the disordered Au/In positions in II were investigated for different hypothetical "EuAu4(Au/In)2" models using the projector-augmented wave method and indicate that these structures attempt to optimize the frequencies of the heteroatomic Au-In contacts. A chemical bonding analysis on two "EuAu5In" and "EuAu4In2" models employed the TB-LMTO-ASA method and reveals that the subtle interplay between the local atomic environments and the bond energies determines the structural and site preferences for these systems.

    Introduction Malgré les efforts d'éducation à la santé, les jeunes continuent d'adopter des comportements sexuels à risques, susceptibles d'avoir des répercussions importantes sur leur santé. Cette étude visait à analyser les facteurs associés à la précocité sexuelle et au multipartenariat chez les jeunes de 19-24 ans de Bobo-Dioulasso. Méthodes Il s'agit d'une étude quantitative et transversale. Les données d'enquête ont été recueillies en décembre 2014 à Bobo-Dioulasso (Burkina Faso), auprès de 573 jeunes de 15 à 24 ans. Ces enquêtés ont été sélectionnés par un sondage en grappes à deux degrés. Des facteurs à risques relatifs à la précocité sexuelle et au multipartenariat ont été analysés à l'aide du logiciel Stata IC 13. Le seuil de signification de Pdes enquêtés (54%) étaient sexuellement actifs dont 14% avant l'âge de 16 ans. Le multipartenariat sexuel avait été observé chez 24% des jeunes sexuellement actifs.

    Full Text Available Lorsqu’il s’agit d’étudier les rapports des pays arabes à la mondialisation, il est nécessaire d’évoquer l’islam. En tant que facteur local, la symbolique islamique offre des ressources de légitimation au pouvoir. Le cas marocain illustre bien la manière dont les rapports existant entre le Makhzen et le répertoire religieux (Amīr al-Mu’minīne, la bayca , la chérifibilité…  font de l’introduction de la modernité un simple espace virtuel et fonctionnel. L’émergence de la contestation islamiste participe à la consécration du répertoire traditionnel. D’autre part, depuis les trois dernières décennies, l’essor de l’islam mondialisé offre au Maroc des opportunités politiques à l’échelle mondiale. Ceci est observable au niveau du rôle joué par le pays dans le cadre de la diplomatie islamique (OCI, ISESCO…  ou au niveau de son positionnement dans l’islam européen. La gestion de l’interaction entre l’islam local et l’islam global, adaptée à la conjoncture internationale, assure le maintien au pouvoir du régime.One cannot study the relationships between Arab countries and globalization without taking Islam into account for it offers symbolic support to legitimizing local power. Morocco is a good example : the relations between the royal court (Makhzen and Islamic features such as being the Commander of the Faithful or Sheriffhood make of modernity a mere virtual or functional sphere. Even the emergence of Islamic contestation contributes to the consecration of the traditional repertory. On the other hand, the rise of world Islam during the last thirty years has opened up political opportunities for Morocco on the international stage – for instance the agencies of Islamic diplomacy (OCI, ISESCO or the quest for a new role in European Islam. By managing the interaction between the local and the global, the regime is able to keep itself in power.

  10. Probing the quenching of CdSe/ZnS qdots by Au, Au/Ag, and Au/Pd nanoparticles.

    Han, Hyunjoo; Valle, Valerie; Maye, Mathew M

    2012-11-02

    The resonance energy transfer between CdSe/ZnS quantum dots (qdots) and three metallic nanoparticles (NPs) with different surface plasmon resonance (SPR) characteristics were studied. Gold, gold/silver and gold/palladium NPs were used as energy acceptors for qdots with donor emission at 570 nm. Due to the different spectral overlaps between the SPR signatures and qdot emission, varied energy transfer characteristics were observed. The energy transfer was quantified via the Stern-Volmer relationship, since in this study the energy transfer was collision based. The Au/Ag and Au/Pd NPs in particular showed high K(SV) values, while the Au NPs showed much lower energy transfer efficiency. Since the NPs used in this study were relatively large (d ~ 15-20 nm), the experimental system was also influenced by the NP extinction coefficients of ≈10(8) M(-1) cm(-1). To address this potential inner filter effect, the quenching profiles were normalized by SPR transmittance. The results are important to the field, as many of these classes of nanomaterials are being employed in energy transfer based studies, as well as in colorimetric sensing.

    Varlet, Madeleine

    Le recours aux modeles et a la modelisation est mentionne dans la documentation scientifique comme un moyen de favoriser la mise en oeuvre de pratiques d'enseignement-apprentissage constructivistes pour pallier les difficultes d'apprentissage en sciences. L'etude prealable du rapport des enseignantes et des enseignants aux modeles et a la modelisation est alors pertinente pour comprendre leurs pratiques d'enseignement et identifier des elements dont la prise en compte dans les formations initiale et disciplinaire peut contribuer au developpement d'un enseignement constructiviste des sciences. Plusieurs recherches ont porte sur ces conceptions sans faire de distinction selon les matieres enseignees, telles la physique, la chimie ou la biologie, alors que les modeles ne sont pas forcement utilises ou compris de la meme maniere dans ces differentes disciplines. Notre recherche s'est interessee aux conceptions d'enseignantes et d'enseignants de biologie au secondaire au sujet des modeles scientifiques, de quelques formes de representations de ces modeles ainsi que de leurs modes d'utilisation en classe. Les resultats, que nous avons obtenus au moyen d'une serie d'entrevues semi-dirigees, indiquent que globalement leurs conceptions au sujet des modeles sont compatibles avec celle scientifiquement admise, mais varient quant aux formes de representations des modeles. L'examen de ces conceptions temoigne d'une connaissance limitee des modeles et variable selon la matiere enseignee. Le niveau d'etudes, la formation prealable, l'experience en enseignement et un possible cloisonnement des matieres pourraient expliquer les differentes conceptions identifiees. En outre, des difficultes temporelles, conceptuelles et techniques peuvent freiner leurs tentatives de modelisation avec les eleves. Toutefois, nos resultats accreditent l'hypothese que les conceptions des enseignantes et des enseignants eux-memes au sujet des modeles, de leurs formes de representation et de leur approche

    The STAR Collaboration presents for the first time two-dimensional di-hadron correlations with identified leading hadrons in 200 GeV central Au + Au and minimum-bias d + Au collisions to explore hadronization mechanisms in the quark gluon plasma. The enhancement of the jet-like yield for leading pions in Au + Au data with respect to the d + Au reference and the absence of such an enhancement for leading non-pions (protons and kaons) are discussed within the context of a quark recombination scenario. The correlated yield at large angles, specifically in the ridge region, is found to be significantly higher for leading non-pions than pions. The consistencies of the constituent quark scaling, azimuthal harmonic model and a mini-jet modification model description of the data are tested, providing further constraints on hadronization.

    Adsorption of Au on W(001) at 450 K up to multilayer structures was investigated. Temperature programmed desorption technique was used in determination of coverage dependent desorption energy (region up to one monolayer). Results were discussed in terms of competitive interactions of Au-Au and Au-W atoms. Simple procedure for prediction of faceting behavior on the interface, basing on the desorption data, was postulated. It was deduced that the Au/W(001) interface should not show faceting tendency after thermal treatment. (author)

    2010-05-01

    Full Text Available Partant d’une analyse de l’oracle d’Œdipe, cet essai développe l’essence de la théorie psychanalytique impliquant une critique des paradigmes de la science moderne. Ce sont ces paradigmes qui la rendent incapable à penser le sujet (y compris le sujet de la science. A cause de cette incapacité un autre champ de savoir s’est développé dans les temps modernes, qui est le champ de la littérature. C’est pourquoi, comme le disait déjà Freud, la psychanalyse comme ‘science du sujet’ et la littérature comme ‘savoir du sujet’ ont de grandes affinités. C’est dans l’engagement idiosyncrasique du sujet dans sa lecture ou son écriture – et là seul – que se trouve le lien entre littérature et psychanalyse. C’est aussi là que se montre la raison pour laquelle toute intention d’appliquer la psychanalyse à la littérature est vouée à l’échec. La psychanalyse aussi bien que la littérature doit confronter son affirmation de la fiction au déni total de la fiction dans les sciences hu-maines. Dans un temps où la civilisation de l’image est en train de remplacer la réalité, cette position conjointe de la littérature et de la psychanalyse est plus que nécessaire.

    Effective photoswitchable europium sulfide nanocrystals with gold nanoparticles using dithiol (DDT: 1,10-decanedithiol) joint molecules, EuS-Au nanosystems, are demonstrated. The TEM image indicates the formation of EuS-Au nanosystems composed of cube-shaped EuS nanocrystals and spherical Au nanoparticles. Under visible-light irradiation, a drastic change of absorption band of EuS-Au nanosystems at around 600 nm was observed. The Faraday effects of EuS-Au nanosystems were estimated using magnetic circular dichroism (MCD) measurements. The effective change of the MCD spectra of EuS-Au nanosystems under visible-light irradiation was successfully observed at around 670 nm for the first time. The effective reversible changes in MCD spectra with the alternative irradiation cycles of visible light (>440 nm) and dark are also presented. The decrease rate of rotation angle at 670 nm of EuS-Au nanosystems is larger than that of absorbance. These results indicate that the effective change of MCD spectra of EuS-Au nanosystems would be dominated not only by a drastic change of absorption band related to enhanced LSPR of Au nanoparticles but also by specific interaction between EuS and Au in nanosystem under irradiation.

    With the use of an on-line isotope separator, the {alpha} activity of {sup 186}Au was identified for the first time. Only one {alpha} group ({ital E}{sub {alpha}}=4653{plus minus}15 keV) was observed. This transition was found not to be in coincidence with {gamma} rays so that it probably proceeds either to the {sup 182}Ir ground state or to a low-lying level whose deexciting {gamma} rays could not be detected. The {alpha}-decay branching was determined to be (8{plus minus}2){times}10{sup {minus}4}% from which a hindrance factor of 1.9{plus minus}0.9 was deduced. The 4653-keV {alpha} transition must therefore connect the 3{sup {minus}} {sup 186}Au ground state with a {sup 182}Ir level with the same spin and configuration.

    Incorporation of nano-sized metals in polymers can transfer their unique features to the host matrix, providing nanocomposite materials with improved optical, electric, magnetic and mechanical properties. In this work, colloidal Au nanorods have been incorporated into PMMA based random co-polymer, properly functionalized with amino groups and the optical and morphological properties of the resulting nanocomposite have been investigated by spectroscopic and AFM measurements. Au nanorods have demonstrated to preserve the plasmon absorption and to retain morphological features upon the incorporation, thus making the final metal modified polymer composite exploitable for the fabrication of plasmonic devices. The prepared nanocomposites have been then patterned by Nano Imprint Lithography technique in order to demonstrate the viability of the materials towards optical applications.

    Full Text Available This manuscript describes a new type of nanomaterial, namely superparamagnetic Au@Co nanochains with optical extinctions in the near infrared (NIR. The Au@Co nanochains were synthesized via a one-pot galvanic replacement route involving a redox-transmetalation process in aqueous medium, where Au salt was reduced to form Au shells on Co seed templates, affording hollow Au@Co nanochains. The Au shells serve not only as a protective coating for the Co nanochain cores, but also to give rise to the optical properties of these unique nanostructures. Importantly, these bifunctional, magneto-optical Au@Co nanochains combine the advantages of nanophotonics (extinction at ca. 900 nm and nanomagnetism (superparamagnetism and provide a potentially useful new nanoarchitecture for biomedical or catalytic applications that can benefit from both activation by light and manipulation using an external magnetic field.

    The combination of photo-responsive azobenzene (AB) and biocompatible Au nanomaterials possesses potential applications in diverse fields such as biosensing and thermotherapy. To explore the influence of azobenzene moieties and Au substrates on the collective switching behavior, two different azobenzene derivatives (rigid biphenyl-controlled versus flexible alkoxyl chain-linked) and three different Au substrates (a planar Au(111) surface, curved Au 102 (SR) 44 and Au 25 (SR) 18 clusters) were chosen to form six Au@AB combinations. A reactive molecular dynamics (RMD) model considering both the torsion and inversion path was implemented to simulate the collective photo-induced cis-to-trans switching process of AB monolayers on Au substrates. The major driving force for isomerization is demonstrated to be the torsion of the C-N[double bond, length as m-dash]N-C dihedral angle, in addition to the minor contribution from an inversion pathway. The isomerization process can be divided into the preliminary conformation switching stage and the later relaxation stage, in which a gradual self-organization is observed for 40 ps. The Au substrate affects the packing structure of the AB monolayer, while the choice of different kinds of ABs tunes the intermolecular interaction in the monolayer. Flexible alkoxyl-linked F-AB may achieve much faster conversion on Au clusters than on the surface. For rigid biphenyl-based R-AB anchored on Au nanoparticles (AuNPs), a competitive torsion between the biphenyl and C-N[double bond, length as m-dash]N-C dihedral may delay the C-N[double bond, length as m-dash]N-C dihedral torsion and the following isomerization process. After the R-AB molecules were anchored on the Au(111) surface, the strong π-π stacking between biphenyl units accelerates the collective isomerization process. A curvature-dependent effect is observed for R-AB SAMs on different-sized substrates. The cooperation between functional AB monolayers and the Au substrate

    We provide the first direct observations of interstellar H+ and He+ pickup ions in the solar wind from 22 to 38 au. We use the Vasyliunas and Siscoe model functional form to quantify the pickup ion distributions, and while the fit parameters generally lie outside their physically expected ranges, this form allows fits that quantify variations in the pickup H+ properties with distance. By ∼20 au, the pickup ions already provide the dominant internal pressure in the solar wind. We determine the radial trends and extrapolate them to the termination shock at ∼90 au, where the pickup H+ to core solar wind density reaches ∼0.14. The pickup H+ temperature and thermal pressure increase from 22 to 38 au, indicating additional heating of the pickup ions. This produces very large extrapolated ratios of pickup H+ to solar wind temperature and pressure, and an extrapolated ratio of the pickup ion pressure to the solar wind dynamic pressure at the termination shock of ∼0.16. Such a large ratio has profound implications for moderating the termination shock and the overall outer heliospheric interaction. We also identify suprathermal tails in the H+ spectra and complex features in the He+ spectra, likely indicating variations in the pickup ion history and processing. Finally, we discover enhancements in both H+ and He+ populations just below their cutoff energies, which may be associated with enhanced local pickup. This study serves to document the release and serves as a citable reference of these pickup ion data for broad community use and analysis.

    Lateral flow assay strips (LFASs) with Au nanoparticles (NPs) have been widely used as a probe for biomarkers in point-of-care testing; however, there still remain challenges in detection sensitivity and quantitative analysis. In this study, we developed a surface-enhanced Raman scattering (SERS)-based LFAS for quantitative analysis of a biomarker in the low concentration range. Moreover, apart from conventional Au NPs, three other types of citrate-capped Au-Ag bimetallic NPs: Au core with Ag shell NPs (Au@Ag NPs), rattle-like Au core in Ag-Au shell NPs (Au@Ag-Au NPs) and Ag-Au NPs were prepared and functionalized, and their solution-based SERS activities were comprehensively studied by experimental measurement and theoretical analysis. The results clearly indicated that the citrate-capped Au@Ag-Au NPs exhibited the highest SERS activity among the probes tested. Au@Ag-Au NPs were used as both optical and SERS probes in a SERS-based LFAS. In the presence of the analyte at high concentrations, a purple color appeared in the test zone. Highly sensitive and quantitative analysis was realized by measurement of SERS signals from the test lines. One of the most specific markers for cardiac injury, cardiac troponin I (cTnI), was chosen as the detection model. The detection limit of the SERS-based LFAS for cardiac troponin I was 0.09 ng/mL, lowered by nearly 50 times compared with visual results, and could be further lowered by optimization. These results demonstrated that the SERS-based LFAS using citrate-capped Au@Ag-Au NPs as probes can be a powerful tool for highly sensitive and quantitative detection of biomarkers. Graphical abstract A surface-enhanced Raman scattering (SERS)-based lateral flow assay strip using rattle-like Au core in Ag-Au shell (Au@Ag-Au) nanoparticles as probes was developed for quantitative analysis of a biomarker, with a detection limit nearly 50 times lower than that of visual assessment.

    An Au25 cluster protected by azobenzene derivative thiolates (S-Az) ([Au25(S-Az)18]-) was synthesized with the aim of producing a photoresponsive Au25 cluster. The matrix-assisted laser desorption/ionization mass spectrum of the product revealed that [Au25(S-Az)18]- was synthesized in high purity. Optical absorption spectra of [Au25(S-Az)18]- obtained before and after photoirradiation suggest that the azobenzenes in the ligands of Au25(S-Az)18 isomerize with an efficiency of nearly 100%, both from the trans to cis conformation and from the cis to trans conformation. Furthermore, the redox potential and optical absorption of Au25(S-Az)18 were found to change reversibly due to photoisomerization of azobenzenes.An Au25 cluster protected by azobenzene derivative thiolates (S-Az) ([Au25(S-Az)18]-) was synthesized with the aim of producing a photoresponsive Au25 cluster.

    BiFeO{sub 3} (BFO) nanoparticles was synthesized via sol–gel technique, and successfully loaded with small sizes of gold nanoparticles (Au NPs) by impregnation-reduction method to extremely enhance the BFO photocatalytic activity. The obviously stronger optical absorption of Au/BFO observed from the UV–vis diffuse reflectance spectrum confirmed that the surface plasmon resonance (SPR) effect occured on the surface of Au NPs. And the surface plasmon-induced localized electric field could allow the formation of electron/hole pairs in the near surface region of BFO which can migrate to the surface without undergoing electron/hole (e{sup −}/h{sup +}) pair recombination. The more electrons and holes formed, the more ·OH will be generated to decompose the CR solution. When the gold loading in Au/BFO nanoparticles is 3.36 wt%, the obtained Au/BFO catalyst exhibits best photocatalytic activity evaluated by photocatalysis degradation of Congo red (CR) solution under the visible light irradiation.

    Introduction Il est question dans notre travail d’étudier le SP et l'OB et les facteurs associés dans la population âgée de 20 ans ou plus. Méthodes Notre échantillon a été obtenu à partir d'une enquête sur les pathologies cardiovasculaires dans le District de Bamako et impliquant 2199 sujets de 5-104 ans, en sélectionnant tous les sujets âgés d'au moins 20 ans (1162). Pour chaque sujet, l'IMC, rapport taille / hanche et le tour de taille ont été déterminées. Les données ont été analysées avec SPSS 12. Résultats L’âge moyen était de 36,86 années, 61,4% étaient des femmes, 49,7% dans le secteur informel et 38,0% avaient réalisé l'enseignement primaire. Facteurs de risque cardiovasculaires étaient l'inactivité physique (72,4%), le tabagisme (12,2%) et hypertension (26,7%). La prévalence de l'obésité était de 8,8 et 14,7% respectivement sur la base de l'indice de masse et le tour de taille. Conclusion Le SP et l'OB sont à prendre en compte dans les mesures de politique sanitaire que dans la pratique quotidienne des professionnels de santé, il est peut-être plus utile d'utiliser plusieurs paramètres pour être à même de bien stratifier nos patients par rapport à leur risque.

    A facile synthetic route was developed to make Au nanowires (NWs) from surfactant-mediated bio-mineralization of a genetically engineered M13 phage with specific Au binding peptides. From the selective interaction between Au binding M13 phage and Au ions in aqueous solution, Au NWs with uniform diameter were synthesized at room temperature with yields greater than 98 % without the need for size selection. The diameters of Au NWs were controlled from 10 nm to 50 nm. The Au NWs were found to be active for electrocatalytic oxidation of CO molecules for all sizes, where the activity was highly dependent on the surface facets of Au NWs. This low-temperature high yield method of preparing Au NWs was further extended to the synthesis of Au/Pt core/shell NWs with controlled coverage of Pt shell layers. Electro-catalytic studies of ethanol oxidation with different Pt loading showed enhanced activity relative to a commercial supported Pt catalyst, indicative of the dual functionality of Pt for the ethanol oxidation and Au for the anti-poisoning component of Pt. These new one-dimensional noble metal NWs with controlled compositions could facilitate the design of new alloy materials with tunable properties. PMID:24910712

    Au38(SR)24 is one of the most extensively investigated gold nanomolecules along with Au25(SR)18 and Au144(SR)60. However, so far it has only been prepared using aliphatic-like ligands, where R = –SC6H13, -SC12H25 and –SCH2CH2Ph. Au38(SCH2CH2Ph)24 when reacted with HSPh undergoes core-size conversion to Au36(SPh)24, and existing literature suggest that Au38(SPh)24 cannot be synthesized. Here, contrary to prevailing knowledge, we demonstrate that Au38(SPh)24 can be prepared if the ligand exchanged conditions are optimized, without any formation of Au36(SPh)24. Conclusive evidence is presented in the form of MALDI-MS, ESI-MS characterization, and optical spectra of Au38(SPh)24 in a solid glass form showing distinct differences from that of Au38(S-aliphatic)24. Theoretical analysis confirms experimental assignment of the optical spectrum and shows that the stability of Au38(SPh)24 is comparable to that of its aliphatic analogues, but results from different physical origins, with a significant component of ligand-ligand attractive interactions.

    A new aromatic thiolate protected gold nanomolecule Au99(SPh)42 has been synthesized by reacting the highly stable Au144(SCH2CH2Ph)60 with thiophenol, HSPh. The ubiquitous Au144(SR)60 is known for its high stability even at elevated temperature and in the presence of excess thiol. This report demonstrates for the first time the reactivity of the Au144(SCH2CH2Ph)60 with thiophenol to form a different 99-Au atom species. The resulting Au99(SPh)42 compound, however, is unreactive and highly stable in the presence of excess aromatic thiol. The molecular formula of the title compound is determined by high resolution electrospray mass spectrometry (ESI-MS) and confirmed by the preparation of the 99-atom nanomolecule using two ligands, namely, Au99(SPh)42 and Au99(SPh-OMe)42. This mass spectrometry study is an unprecedented advance in nanoparticle reaction monitoring, in studying the 144-atom to 99-atom size evolution at such high m/z (∼12k) and resolution. The optical and electrochemical properties of Au99(SPh)42 are reported. Other substituents on the phenyl group, HS-Ph-X, where X = -F, -CH3, -OCH3, also show the Au144 to Au99 core size conversion, suggesting minimal electronic effects for these substituents. Control experiments were conducted by reacting Au144(SCH2CH2Ph)60 with HS-(CH2)n-Ph (where n = 1 and 2), bulky ligands like adamantanethiol and cyclohexanethiol. It was observed that conversion of Au144 to Au99 occurs only when the phenyl group is directly attached to the thiol, suggesting that the formation of a 99-atom species is largely influenced by aromaticity of the ligand and less so on the bulkiness of the ligand.

À travers le principe de la pleine propriété de soi, les libertariens défendent la liberté entière de chacun de vivre comme il l���entend, pourvu que les droits des autres soient respectés. Apparemment, ce principe n’a pas grand-chose à nous dire sur ce que nous sommes moralement autorisés à nous faire à nous-mêmes ou non. Certains libertariens, comme Vallentyne, soutiennent toutefois que le principe de la pleine propriété de soi est incompatible avec l’existence de devoirs envers soi. La pleine propriété de soi impliquerait l’indifférence morale du rapport à soi. Je soutiens dans cet article que le principe de la pleine propriété de soi n’implique pas que ce que nous nous faisons à nous-mêmes soit moralement indifférent. Je veux aussi montrer que même si les libertariens, et en particulier Vallentyne, soutiennent la thèse de l’indifférence morale du rapport à soi, celle-ci n’est pas liée à la thèse de la pleine propriété de soi, mais bien plutôt à leur subjectivisme moral.ABSTRACTI ask in this article what the libertarian principle of full self-ownership has to say about volontary actions directed towards oneself.

Apparently, this principle doesn’t have much to say about what we are morally allowed to do to ourselves or not. Some libertarians, however, like Vallentyne, maintain that, if we have duties or obligations to ourselves, then we cannot be full self-owner. In this perspective, full self-ownership would imply that what we do to ourselves is morally indifferent. I want to show in this article that full self-ownership is compatible with the

    La localisation cutanée de la maladie tuberculeuse demeure une forme rare et représente seulement 2,1% des localisations. L'objet de cette étude est de rapporter le profil épidémiologique, anatomoclinique et évolutif des cas de tuberculose ganglio-cutanée diagnostiqués dans un CHU au Burkina Faso. La fréquence de la tuberculose cutanée est très faible au CHUSS. Six cas ont été diagnostiqués entre 2004 et 2010, soit une fréquence de un cas par an. La durée d’évolution des cas allait de deux jusqu’à dix ans avant leur diagnostic. Les lésions observées étaient: trois scrofulodermes, trois gommes, une tuberculose testiculaire associée à un mal de Pott, un cas de polyadénopathies et des cicatrices atropho-rétractiles dans la plupart des cas. Sur le plan anatomopathologique, des granulomes tuberculoïdes ont été mis en évidence dans tous les cas avec une forte réaction tuberculinique à l'IDR. Sous antituberculeux pendant six mois, l’évolution a été bonne dans tous les cas mais au prix de séquelles cutanées cicatricielles inesthétiques. Son ampleur reste peut-être encore méconnue. Le renforcement du plateau technique du CHU et une bonne collaboration interdisciplinaire contribuerait à un meilleur diagnostic et prise en charge de cette affection. PMID:24648863

    2009-12-29

    Metal-oxide heterostructures have been attracting considerable attention in recent years due to various technological applications. We present results of electronic structure and transport calculations for the Au-MgO-Au (metal-insulator-metal) heterostructure based on density-functional theory and the nonequilibrium Green’s functions method. The dependence of the conductance of the heterostructure on the thickness of the MgO interlayer and the interface spacing is studied. In addition, we address the effects of O vacancies. We observe deviations from an exponentially suppressed conductance with growing interlayer thickness caused by Au-O chemical bonds. Electronic states tracing back to O vacancies can increase the conductance. Furthermore, this effect can be enhanced by enlarging the interface spacing as the vacancy induced Mg states are shifted toward the Fermi energy.

    Elliptic flow from nuclear collisions is a hadronic observable sensitive to the early stages of system evolution. We report first results on elliptic flow of charged particles at midrapidity in Au+Au collisions at sqrt(s_NN)=130 GeV using the STAR TPC at RHIC. The elliptic flow signal, v_2, averaged over transverse momentum, reaches values of about 6% for relatively peripheral collisions and decreases for the more central collisions. This can be interpreted as the observation of a higher degree of thermalization than at lower collision energies. Pseudorapidity and transverse momentum dependence of elliptic flow are also presented.

    The first measurements of light antinucleus production in Au + Au collisions at the Relativistic Heavy-Ion Collider are reported. The observed production rates for d and /sup 3/He are much larger than in lower energy nucleus-nucleus collisions. A coalescence model analysis of the yields indicates that there is little or no increase in the antinucleon freeze-out volume compared to collisions at CERN SPS energy. These analyses also indicate that the 3He freeze-out volume is smaller than the d freeze-out volume. (22 refs).

  15. Nuclear Stopping in Central Au+Au Collisions at RHIC Energies

    Full Text Available Nuclear stopping in central Au+Au collisions at relativistic heavy-ion collider (RHIC energies is studied in the framework of a cascade mode and the modified ultrarelativistic quantum molecular dynamics (UrQMD transport model. In the modified mode, the mean field potentials of both formed and “preformed” hadrons (from string fragmentation are considered. It is found that the nuclear stopping is increasingly influenced by the mean-field potentials in the projectile and target regions with the increase of the reaction energy. In the central region, the calculations of the cascade model considering the modifying factor can describe the experimental data of the PHOBOS collaboration.

    Many-body perturbation theory (MBPT) calculations are an adequate tool for the description of the structure of highly charged multi-electron ions and for the analysis of their spectra. They demonstrate this by way of a re-investigation of n=3, {Delta}n=0 transitions in the EUV spectra of Na-, Mg-, Al-like, and Si-like ions of Au that have been obtained previously by heavy-ion accelerator based beam-foil spectroscopy. They discuss the evidence and propose several revisions on the basis of the multi-reference many-body perturbation theory calculations of Ne- through P-like ions of Au.

  18. Measurements of direct photons in Au+Au collisions with PHENIX

    2014-01-01

    The PHENIX experiment has published direct photon yields and elliptic flow coefficients $v_2$ from Au+Au collisions at RHIC energies. These results have sparked much theoretical discussion. The measured yields and flow parameters are difficult to reconcile in current model calculations of thermal radiation based on hydrodynamic time evolution of the collision volume. Our latest analyses which use high statistics data from the 2007 and 2010 runs allow the determination of direct photon yields with finer granularity in centrality and photon momentum and down to $p_T$ as low as 0.4 GeV/$c$. We will summarize the current status and present new results from PHENIX.

    A facile method has been developed to synthesize Au/Pd core-shell nanoparticles via galvanic replacement of Cu by Pd on hollow Au nanospheres. The unique nanoparticles were characterized by X-ray diffraction, X-ray photoelectron spectroscopy, transmission electron microscopy, ultraviolet-visible spectroscopy, and electrochemical measurements. When the concentration of the Au solution was decreased, grain size of the polycrystalline hollow Au nanospheres was reduced, and the structures became highly porous. After the Pd shell formed on these Au nanospheres, the morphology and structure of the Au/Pd nanoparticles varied and hence significantly affected the catalytic properties. The Au/Pd nanoparticles synthesized with reduced Au concentrations showed higher formic acid oxidation activity (0.93 mA cm-2 at 0.3 V) than the commercial Pd black (0.85 mA cm-2 at 0.3 V), suggesting a promising candidate as fuel cell catalysts. In addition, the Au/Pd nanoparticles displayed lower CO-stripping potential, improved stability, and higher durability compared to the Pd black due to their unique core-shell structures tuned by Au core morphologies.

    Conductive Au-biopolymer composites have promising applications in tissue engineering such as nerve tissue regeneration. In this study, silk fibroin nanofibers were formed in aqueous solution by regulating silk self-assembly process and then used as template for Au nanowire fabrication. We performed the synthesis of Au seeds by repeating the seeding cycles for several times in order to increase the density of Au seeds on the nanofibers. After electroless plating, densely decorated Au seeds grew into irregularly shaped particles following silk nanofiber to fill the gaps between particles and finally form uniform continuous nanowires. The conductive property of the Au-silk fibroin nanowires was studied with current-voltage ( I-V) measurement. A typical ohmic behavior was observed, which highlighted their potential applications in nerve tissue regeneration.
