    1999-01-01

    To improve efficiency, some large retailers, suppliers, and distributors have begun to conduct business-to-business commerce electronically. This practice could grow rapidly if the Internet becomes the primary low-cost network for such transactions. Before the Internet can fully support business-to-business commerce, however, companies must overcome several technological and security obstacles.

  7. Effets des electrons secondaires sur l'ADN

    Science.gov (United States)

    Boudaiffa, Badia

    Les interactions des electrons de basse energie (EBE) representent un element important en sciences des radiations, particulierement, les sequences se produisant immediatement apres l'interaction de la radiation ionisante avec le milieu biologique. Il est bien connu que lorsque ces radiations deposent leur energie dans la cellule, elles produisent un grand nombre d'electrons secondaires (4 x 104/MeV), qui sont crees le long de la trace avec des energies cinetiques initiales bien inferieures a 20 eV. Cependant, il n'y a jamais eu de mesures directes demontrant l'interaction de ces electrons de tres basse energie avec l'ADN, du principalement aux difficultes experimentales imposees par la complexite du milieu biologique. Dans notre laboratoire, les dernieres annees ont ete consacrees a l'etude des phenomenes fondamentaux induits par impact des EBE sur differentes molecules simples (e.g., N2, CO, O2, H2O, NO, C2H 4, C6H6, C2H12) et quelques molecules complexes dans leur phase solide. D'autres travaux effectues recemment sur des bases de l'ADN et des oligonucleotides ont montre que les EBE produisent des bris moleculaires sur les biomolecules. Ces travaux nous ont permis d'elaborer des techniques pour mettre en evidence et comprendre les interactions fondamentales des EBE avec des molecules d'interet biologique, afin d'atteindre notre objectif majeur d'etudier l'effet direct de ces particules sur la molecule d'ADN. Les techniques de sciences des surfaces developpees et utilisees dans les etudes precitees peuvent etre etendues et combinees avec des methodes classiques de biologie pour etudier les dommages de l'ADN induits par l'impact des EBE. Nos experiences ont montre l'efficacite des electrons de 3--20 eV a induire des coupures simple et double brins dans l'ADN. Pour des energies inferieures a 15 eV, ces coupures sont induites par la localisation temporaire d'un electron sur une unite moleculaire de l'ADN, ce qui engendre la formation d'un ion negatif transitoire

    Full Text Available Electronic correspondence is a highly dynamic genre within the business world in which Register Variation (RV is frequently used as a tool to improve communication but it often can lead to misunderstanding. In order to shed some light on this still unexplored area, the present study firstly offers a practical approach to classify and analyse RV within professional communication. After this, it reviews previous studies on email writing to apply their findings to this approach and, in the third part of the study, a corpus of recent business emails in English is analysed to examine how the key parameters of RV are currently used within this genre. The results will show that, not only the context, but also the roles and intentions of the senders influence an email’s register, often causing internal oscillations between different registers within the same text.La correspondencia electrónica es un género comunicativo de especial dinamismo dentro del mundo empresarial en el que la variación de registros se utiliza como herramienta para mejorar la interacción y las relaciones entre los interlocutores, pero que a menudo también genera confusión y malentendidos. Para aportar luz a esta área, el presente trabajo ofrece una aproximación práctica para la clasificación y el análisis de los registros lingüísticos dentro de la comunicación profesional. A continuación, revisa los estudios previos sobre este género con el fin de adaptar sus resultados a la teoría propuesta. Finalmente, se analiza un corpus de mensajes escritos en inglés para examinar el funcionamiento de los registros dentro de este género. Los resultados mostrarán que, no solo el contexto situacional, sino sobre todo los roles e intenciones de los emisores determinan el registro de un mensaje, provocando a menudo oscilación interna entre varios registros dentro del mismo texto.

    2002-01-01

    Exponential advances in the technology sector and computer industry have benefited the science and practice of radiology. Modalities such as digital radiography, computed radiography, computed tomography, magnetic resonance imaging, ultrasound, digital angiography, and gamma cameras are all capable of producing DICOM compliant images. Text can likewise be acquired using voice recognition technology (VRT) and efficiently rendered into a digital format. All of these digital data sets can subsequently be transferred over a network between machines for display and further manipulation on workstations. Large capacity archiving units are required to store these voluminous data sets. The enterprise components of radiology departments and imaging centers--radiology information systems (RIS) and picture archiving and communications systems (PACS)--have thus undergone a transition from hardcopy to softcopy. When preparing to make transition to a digital environment, the first step is introspective. A detailed SWOT (strengths, weaknesses, opportunities and threats) analysis, with a focus on the status of "electronic preparedness," ensues. The next step in the strategic planning process is to formulate responses to the following questions: Will this technology acquisition provide sufficient value to my organization to justify the expense? Is there a true need for the new technology? What issues or problems does this technology address? What customer needs will this technology satisfy today and tomorrow? How will the organization's shareholders benefit from this technology? The answers to these questions and the questions that they in turn generate will stimulate the strategic planning process to define demands, investigate technology and investment options, identify resources and set goals. The mission of your radiology center will determine what you will demand from the electronic environment. All radiology practices must address the demand of clinical service. Additional

    Full Text Available Risk should not be understood as a destructive phenomenon, but bear in mind that managers who know how to use it can lead to real opportunities. Manager must first recognize the existence of risk, namely to identify and then use specific methods to avoid or reduce the risk. The purpose of this paper is to enter the world, at all simple, of risk management, relatively easy concept to understand but not so easy to put into practice. Of course, the approach relates primarily at the risks inherent of the business in digital environments, but they not represent only a particular case of the risks they are exposed, in general, the companies. In the paper we put in evidence the significance in general business, risks in e-business, then we added a description of the types of security risks, an exemplification of these and a series of test scenarios, and finally to make a analysis of operational solutions of risk management

    Full Text Available Les grandes entreprises ont-elles un rôle à jouer dans la réduction de la pauvreté ? Si tel est le cas, quels sont les moyens d'action qu'elles peuvent et souhaitent mettre en œuvre ? Depuis des décennies, ce sont principalement l’intervention publique, les agences de développement internationales et les ONG qui relèvent le défi de l'éradication de la pauvreté. En réponse aux questionnements sur la responsabilité des entreprises, de plus en plus d'initiatives ont vu le jour, ayant pour objectif la réduction des impacts négatifs des entreprises dans les domaines sociaux et environnementaux. Au-delà de ces approches réactives, certains sont convaincus que des solutions existent, qui s’appuient sur des projets plus proactifs et placent les questions sociales au cœur de la vision d'entreprise. Le Social Business est l'une de ces approches ambitieuses. Il incite l'entreprise à compléter ses pratiques traditionnelles en matière d’innovation et de recherche et développement par des approches d’« open innovation », encastrées localement, visant la création d'un marché tout en cherchant à répondre aux enjeux de pauvreté. Veolia Eau, en collaboration avec Muhammad Yunus, le fondateur de la Grameen Bank, a décidé d'expérimenter ce type de modèle d'entreprise innovant au Bangladesh, fortement touché par le problème de santé publique lié à l'eau des puits, naturellement contaminée en arsenic. Le processus expérimental permet à la joint-venture de s'adapter à la nouveauté et à la complexité (contextuelle, socioculturelle et commerciale, de donner naissance progressivement à un marché réel et de tester un modèle d'entreprise novateur. Cet apprentissage par la pratique amène également une grande entreprise comme Veolia Eau à chercher de nouveaux compromis entre rentabilité à court terme et contribution positive à la société par le biais de modèles économiques qui intègrent les probl

    Directory of Open Access Journals (Sweden)

    2013-12-01

    Full Text Available The authors of the article analyze the concept "electronic environment". Having studied a range of academic literature sources and other sources, the authors of the article have drawn a conclusion that the academic writings do not provide a definition of "electronic environment". Furthermore, the various opinions among specialists regarding this concept often differ. Meanwhile, there are several explanations of the term "cyberspace" overlapping the concept of "electronic environment", and these terms are often believed to be synonyms. To understand what the term "electronic environment" means and to properly and correctly employ this concept in entrepreneurship, the authors have performed a lexicographic analysis of this concept by comparing reciprocal concepts. As a result of the research, the authors propose their view on what, in their opinion, "electronic environment" is and what its connection to the concept "cyberspace" is. The topicality of the article lies in the fact that often entrepreneurs and specialists of public and other institutions, when using these terms, imply completely different concepts. It can lead to misunderstanding and misinterpreting the information, as well as to encumbering the understanding of tasks, problems, etc.

    1998-01-01

    Three workshops, held in Lancaster, Orange County and Compton, were produced by the Los Angeles Regional Technology Alliance (LARTA) and NASA Far West Technology Transfer Center (FWRTTC). The workshops were held on December 12, 1997, February 5, 1998, and March 30, 1998, respectively. The purpose behind these workshops was to spread information regarding NASA procurement opportunities to small businesses in the region. This was accomplished by inviting economic and business development organizations to the three workshops, presenting NASA procurement resources to them, and asking them to distribute this information to the small businesses in their communities. With the assistance of LARTA, marketing and publicity in the form of direct mail, telemarketing, and promotion via a web site was implemented to publicize the workshops. These methods were remarkably effective because they enabled the workshops to attain its full capacity. Further publicity was provided by Wendy Reed of Valley Focus Magazine, an Antelope Valley Magazine aimed at business people. Her article entitled, "Doing Business with the Government" recapped the Lancaster workshop that she had attended and made references to several presentations. In the article, she discussed selling to the government via electronic commerce, and specifically mentioned Robert Medina, the NASA Dryden Small Business Specialist, as a contact person for those interested in pursuing procurement opportunities. The feedback provided by the participants is illustrated by the enclosed graphs and charts. These figures represent the number of participants who have frequented web sites presented at workshops, specifically the NASA procurement resources, and how extensive information dissemination was. Input from participants was favorable and encouraged more NASA Dryden workshops directly to the small business communities.

    The high energy electron beam has less penetration power in comparison with the gamma ray which has been used from before. However, the dose rate of the electron beam is considerably high in comparison with the gamma ray with more than several thousand times. Therefore, the irradiation of the product can be done in a short time, and there are cheap characteristics further in the irradiation cost as well. And, an electron beam is the technology which is very easy to accept in the country of a nuclear allergy constitution like our country so that it may not use radioactive substance. This time, I'd like to think about the present condition of the electron beam irradiation service business and a future based on the experience of Tsukuba EBcenter until now. (J.P.N.)

    Jong-min Choe

    2017-01-01

    Full Text Available Based on the degree of information sharing between buyers and suppliers as well as the level of supplier power, we suggested a framework that can be useful for classifying types of business to business (B2B electronic commerce (EC in the manufacturing firms. According to this framework, four kinds of B2B EC were theoretically proposed, classified, and empirically confirmed. These four are: an electronic marketplace, electronic procurement, electronic partnerships, and electronic distribution. Many prior studies have investigated and proposed some kinds of B2B EC. However, these studies focused mostly on one or two types of B2B EC, and did not develop or suggest a framework for the classification of forms of B2B EC. The framework constructed in this research can be utilized variously. Specifically, when a firm wants to initiate B2B EC with its suppliers, this framework can help a firm to decide and select an appropriate kind of B2B EC. This framework can also be applied to evaluate whether the proper form of B2B EC has been adopted or not.

    The operation of neutron-electron converters designed for measuring thermal neutron fluxes is examined. The principle is to produce short lived isotopes emitting beta particles, by activation, and to measure their activity not by extracting them from the reactor, but directly in the reactor using the emitted electrons to deflect the needle of a galvanometer placed outside the flux. After a theoretical study, the results of the measurements are presented; particular attention is paid to a new type of converter characterized by a layer structure. The converters are very useful for obtaining flux distributions with more than 10{sup 7} neutrons cm{sup -2}*sec{sup -1}. They work satisfactorily in pressurized carbon dioxide at 400 Celsius degrees. Some points still have to be cleared up however concerning interfering currents in the detectors and the behaviour of the dielectrics under irradiation. (authors) [French] On examine le fonctionnement de convertisseurs neutrons electrons destines a des mesures de flux de neutrons thermiques. Le principe est de former par activation des isotopes a periodes courtes et a emission beta et de mesurer leur activite non pas en les sortant du reacteur, mais directement en pile, utilisant les electrons emis pour faire devier l'aiguille d'un galvanometre place hors flux. Apres une etude theorique, on indique des resultats de mesures obtenus, en insistant particulierement sur un nouveau type de convertisseur, caracterise par sa structure stratifiee. Les convertisseurs sont tres interessants pour tracer, des cartes de flux a partir de 10{sup 7} neutrons cm{sup -2}*s{sup -1}. Ils sont utilisables pour des flux de 10{sup 14} neutrons cm{sup -2}*s{sup -1}. Ils fonctionnent correctement dans du gaz carbonique sous pression a 400 C. Des points restent cependant a eclaircir concernant les courants parasites dans les detecteurs et le comportement des dielectriques pendant leur irradiation. (auteur)

    Full Text Available In the past, organisations relied on traditional quantitative metrics, such as Return on Investment (ROI to make decisions when investing in technology. With the advent of electronic commerce (EC, organisations have had to rethink their investment and acquisition decisions due to the strategic nature of electronic commerce. Where ROI measures have failed, they have been replaced with a plethora of organisational driving forces. This paper focuses on the driving forces behind EC adoption by small and medium enterprises (SME's and aims to determine the impact of organisational factors such as size and type of business on EC acquisition criteria. The results of a research study carried out in Sweden are presented and suggest that there exist high levels of significance between the size of the business and customer demand, reduced costs, developing new markets and improvement to marketing as driving forces, and the type of business and customer demand, pressure from competition, increased sales and improvement of relationship with business partners as driving forces for EC adoption.

    Full Text Available Purpose: In current economy, where ICT plays a crucial role for being competitive and effective, businesses are facing higher pressures of flexibility and efficiency than ever before. Transparency is often considered as a suitable mechanism for better market prices and more efficient market environment. Electronic business environment provides the possibility to set up more transparent environment and bring higher competitiveness and efficiency on the market. The paper analyse the impact of transparency on prices in e-procurement.Methodology: Reverse auctions are considered as transparent tool simulating in partial level real competition. Together, it allows to examine several levels of transparency set up in auction negotiation process. The impact of transparency on final prices was analysed on real data using relation based analysis were different situations of transparency set up is compared against achieved final price.Findings: Research results based on real data shows, that generally, the transparency in electronic reverse auction can lead to more negative prices agreed by purchasers as current scientific and commercial promotions.Research limitation: Significance of research results is limited due to still low readiness and skills of e-procurers. The validation of results is needed to realized within longer period of time and from environments with different level of e-readiness. Together, it reveal that transparency is more complex issue where the significance of transparency can reveal its sense in some specific situations on the market and negotiation.Value of paper: Evidenced based research reveal some controversy results which support new scientific efforts in microeconomics and socio-economic impact of ICT fields. Together, it affects real practitioners in way how to use and perceive claimed impact of reverse auction solutions.

    The theoretical characteristics of the electron linear accelerator are: 30 MeV for the energy W{sub S} and 250 mA for the peak current I{sub c}. The main utilization is the intense production of fast neutrons by the reactions ({gamma},n) and ({gamma},f) induced in a target of natural uranium by the accelerated electrons. In the first part of the thesis, relative to the study and the realization of the accelerator, a new equation of dispersion is established analytically when the guide is loaded with round-edged irises. The relation is compared with the equation established by CHU and Hansen, WALKINSHAW, KVASIL in the case of a guide loaded with flat-edged irises. The experimental and theoretical curves of dispersion are compared. The accuracy of every relation of dispersion is estimated. The second part of the thesis is relative to the theoretical study of the electrons dynamics in the guide; it allows the derivation of the parameters of the beam: dispersion of phase, energy, dispersion of energy and the relation W{sub S} = f (I{sub c}). The results relative to the first experiments are given and compared with the theoretical expectations.

    In this report, we are investigating the solar modulation of cosmic electrons, in different ways. By comparing the calculated intensity with the measured intensity of positrons, we can evaluate the solar modulation of positrons, hence the modulation of negatons, since the modulation of negatons is probably the same that for positrons. By comparing the electron spectrum in interstellar space needed to explain the galactic background radio emission with that observed near the earth, we can deduce information about the modulation of electrons. We can investigate the modulation through the observation of its variations during the solar cycle. This different ways lead us to compatible results. In spite of the fact that the precision of the experimental data is poor, the modulation can be represented by: a constant or a form in exp(- K/Ro{beta}) under the rigidity Ro {approx_equal} 0,5 BV; a form in exp(- K/R) or exp(- K/R{beta}) above this rigidity. In addition, the investigation of both electrons and protons displays that the diffusion-convection theory is inadequate to explain all the features of the solar modulation. (author) [French] Dans le present rapport, nous etudions la modulation solaire des electrons cosmiques a l'aide de plusieurs methodes. Par comparaison entre l'intensite calculee et l'intensite mesuree des positons, on peut evaluer la modulation solaire des positons, et aussi des negatons, puisque la modulation des negatons est probablement la meme que celle des positons. Par le calcul, a partir du bruit de fond radio, du flux des electrons a l'exterieur du systeme solaire et sa confrontation avec le flux observe a l'orbite de la Terre permet l'etude de la modulation solaire des electrons. On peut aussi analyser ce phenomene de modulation pour l'etude de ses variations au cours du cycle solaire. Ces diverses methodes donnent des resultats compatibles. En depit de la precision mediocre des donnees experimentales, on peut caracteriser la modulation par: une

    The survival curves (capability of multiplication) of chlorella pyrenoidosa after irradiations can be used for soft electrons (0.65 and 1 MeV), hence penetrating into only 2 to 4 millimeters of water: the algae are laying on porous membranes and the doses are calculated from the power of the electron beam measured by the electric current on a metallic target or by Fricke's dosimetry. With these techniques, it is showed and discussed the part of anoxia in the radioprotection (magnitude or reduction of the dose calculated from the slope of survival curves: 2.5 ) that is more important than the restoration studied by the fractionation of the dose. The 0.65 and 1 MeV electrons have a biologic effect lesser than 180 keV X-rays (RBE - relative biological efficiency - calculated on the slope of survival curves is 0.92 in aerated irradiation, 0.56 in the deoxygenated irradiation). (author) [French] Les courbes de survie clonale (capacite de multiplication) de chlorella pyrenoidosa apres irradiation sont realisables meme avec des electrons peu energetiques (0.65 et 1 MeV), donc peu penetrants, par l'irradiation d'algues deposees sur membrane filtrante et grace au calcul de la dose a partir de l'energie du faisceau mesure par le courant que celui-ci cree dans une cible metallique ou par dosimetrie de Fricke. Par ces techniques, on a montre et discute le role de l'anoxie dans la radioprotection des chlorelles (facteur de reduction de la dose calcule sur la pente des courbes de survie de 2.5) qui est plus important que le pouvoir de restauration etudie par le fractionnement de la dose. Les electrons utilises ont un effet biologique moins grand que les rayons X de 180 keV (l'efficacite biologique relative - EBR - calculee sur la pente des courbes de survie est de 0.9 en presence d'air, 0.6 en presence d'azote)

    The classical theory of the linear accelerator buncher does not fit the experimental measurements of the shape of the bunch of electrons performed at Saclay by the method of the energy spectrum. If the spurious effect of the mode converter at the input of the linac is taken into account the theory can fit the experimental results and also explain the variations of the phase of the bunch on the accelerating sine wave.

Par contre si l'effet parasite du convertisseur de mode a l'entree de l'accelerateur est pris en consideration les resultats theoriques coincident bien avec les resultats experimentaux et permettent en outre d'expliquer les variations du calage en phase des paquets elementaires d'electrons.

  1. Electronic Commerce: a battle on regulation, standards transportation media and business integration

    Directory of Open Access Journals (Sweden)

    Kim Andersen

    1998-11-01

    Full Text Available The drive towards the electronic commerce organisation is both a troublesome and a strifted path for government, enterprises and consumers worldwide. In this article we analyse the evolution of electronic commerce in Denmark during the period 1995-1998 from four perspectives: regulation, standards, transportation media and business integration. The Danish government is stimulating the use of electronic commerce using direct and indirect policy initiatives on central, governmental regulation and establishment of greens enabling self-regulation. Also, the governments own, organisational management is in Denmark seen as a mean to exalt electronic commerce. Onwards, the fist on proprietary standards and the UN/EDIFACT is an ongoing source of delaying, stimulating or reventing electronic commerce depending on the business sector and the size of market actor addressed. In Denmark, the direct access and value added network supporters have so far been the dominating mean to transport the electronic documents in the business transaction. The Internet and XML technology is at the turn of the century challenging the way of doing business within this field. Some view this as the big blue to speed the diffusion of electronic commerce; others are worried that the incentive to investment and pull the partners in the value chain to use EDI might be lost. Finally, our study conclude that the debate on business integration issues is ambiguous and characterised by substantial uncertainty on for example the role of intermediates, direct sale, hyper-shift in business partners and the pull/push of global enterprises at the local markets.

    The aim of this work is to allow the practical execution of the estimated calculation of the electronic devices reliability and to standardize the source and the approach of the calculations while giving a systematic character to their execution mode. The systematic character of the calculations allows a comparison of the reliability of different materials and a rapid control of the calculations validity; at last, it brings out the use conditions of all the components of a set. A reliability calculation made according to the method described here reveals: -components badly used -the relative influence on the reliability of the set, of a component or a components group taking into account of the number, of the characteristics and of the use of these ones. At last, the results of the calculation allows to organize the exploitation (availability) and the maintenance (staff, stock of components) of the materials. The failure rates given in this book are only relating to the components service-life and do not correspond to precocious failures.

    2011-01-01

    Widespread implementation and use of electronic health record (EHR) systems has been recognized by healthcare leaders as a cornerstone strategy for systematically reducing medical errors and improving clinical quality. However, EHR adoption requires a significant capital investment for healthcare providers, and cost is often cited as a barrier. Despite the capital requirements, a true business case for EHR system adoption and implementation has not been made. This is of concern, as the lack of a business case can influence decision making about EHR investments. The purpose of this study was to examine the role of business case analysis in healthcare organizations' decisions to invest in ambulatory EHR systems, and to identify what factors organizations considered when justifying an ambulatory EHR. Using a qualitative case study approach, we explored how five organizations that are considered to have best practices in ambulatory EHR system implementation had evaluated the business case for EHR adoption. We found that although the rigor of formal business case analysis was highly variable, informants across these organizations consistently reported perceiving that a positive business case for EHR system adoption existed, especially when they considered both financial and non-financial benefits. While many consider EHR system adoption inevitable in healthcare, this viewpoint should not deter managers from conducting a business case analysis. Results of such an analysis can inform healthcare organizations' understanding about resource allocation needs, help clarify expectations about financial and clinical performance metrics to be monitored through EHR systems, and form the basis for ongoing organizational support to ensure successful system implementation.

    Electronic cigarettes (e-cigarettes) have attracted considerable attention as a possible alternative to tobacco cigarettes, but uncertainties about their impact on health and indoor air quality as well as their commercial success without a clear regulatory framework are arousing concern. We have therefore tried to summarize the health-related implications of the use of e-cigarettes in order to help physicians and health professionals provide accurate information on this device. Given the lack of unequivocal scientific data on their toxicity and safety, we conclude that at the moment there is no reason to approve e-cigarettes as a safe alternative to tobacco smoke.

    In 1998 by making use of a water Cherenkov detector the Super-Kamiokande Experiment in Japan has measured a deficit of {nu}{sub {tau}} atmospheric neutrinos without observing a corresponding rise in the {nu}{sub e} flux. This phenomenon is understood as neutrino oscillations, a mechanism implying a non vanishing neutrino mass. In 1999 the CHOOZ Experiment has definitely excluded the oscillations {nu}{sub {mu}} {yields} {nu}{sub e} within atmosphere. The OPERA Experiment aims at evidencing the {nu}{sub {mu}} {yields} {nu}{sub {tau}}oscillations through occurrence of {nu}{sub {tau}} and of {nu}{sub {mu}} {yields} {nu}{sub e} oscillations by occurrence of {nu}{sub e} starting from a muon neutrino beam almost totally clean. Such a beam is actually produced at CERN (CNGS beam) in Switzerland and then directed upon the OPERA detector located 732 km southward under Gran Sasso mountains in Italy. The detector consists of more than 200,000 bricks (what amounts to a total mass of 1,800 tons made up of a nuclear emulsion foils / lead foils sandwich. This module structure allows reconstructing with a high spatial resolution ({delta}{sub {theta}} {approx_equal} 1 mrad and {delta}{sub r} {approx_equal} 1 {mu}m) the kink topology created by the {tau} lepton (issued from charged current interaction of a {nu}{sub {tau}} lepton with a lead nucleus) and its decay products. The work reported in this thesis consists in characterization of the electrons needed in the study of {nu}{sub {mu}} {yields} {nu}{sub {tau}}oscillations, with {tau} {yields} e, and the {nu}{sub {mu}} {yields} {nu}{sub e} oscillations, the {nu}{sub e} interacting through charged currents with a lead nucleus and producing an electron. A reconstruction algorithm of the electromagnetic cascades in nuclear emulsion was developed. This algorithm allows reproducing the longitudinal and transverse profiles used in evaluating the electron energies and their identification as well ({pi}/e separation by mean of a neuron

  12. Protection des ions organiques contre les dommages induits a l'ADN par les electrons de basse energie

    Science.gov (United States)

    Dumont, Ariane

    Il a ete demontre que les electrons de basse energie (EBE) peuvent induire des cassures simple brin (CSB) a l'ADN, via la formation d'anions transitoires qui decroissent par attachement dissociatif, ou dans d'autres etats electroniques dissociatifs menant a la fragmentation. Afin d'effectuer une etude complete des effets des electrons de basse energie sur la matiere biologique, il est necessaire de comprendre leur mecanismes d'interaction non seulement avec l'ADN, mais avec les constituants de son environnement. Les histones sont une composante importante de l'environnement moleculaire de l'ADN. Leur charge positive leur permet de s'associer aux groupements phosphate anionique de l'ADN. Le role principal de ces proteines basiques consiste a organiser l'ADN et l'empaqueter afin de former la chromatine. Les cations sont une autre composante importante de la cellule; ils jouent un role dans la stabilisation de la conformation B de l'ADN in vitro par leurs interactions avec les petits et grands sillons de l'ADN, ainsi qu'avec le groupement phosphate charge negativement. Avec les histones, ils participent egalement a la compaction de l'ADN pour former la chromatine. Cette etude a pour but de comprendre comment la presence d'ions organiques (sous forme de Tris et d'EDTA) a proximite de l'ADN modifie le rendement de cassures simple brin induit par les electrons de basse energie. Le Tris et l'EDTA ont-ete choisis comme objet d'etude, puisqu'en solution, ils forment le tampon standard pour solubiliser l'ADN dans les experiences in vitro (10mM Tris, 1mM EDTA). De plus, la molecule Tris possede un groupement amine alors que l'EDTA possede 4 groupements carboxyliques. Ensembles, ils peuvent se comporter comme un modele simple pour les acides amines. Le ratio molaire de 10 :1 de Tris par rapport a l'EDTA a pour but d'imiter le comportement des histones qui sont riches en arginine et lysine, acides amines possedant un groupement amine charge positivement additionnel.

    Full Text Available Le rôle du business a été traditionnellement ignoré dans les débats internationaux portant sur le développement économique et la lutte contre la pauvreté. Toutefois, le succès mondial récent du secteur de la téléphonie mobile et son essor rapide sur les marchés émergents au cours des deux dernières décennies ont imposé une remise en question. Au lieu de stratégies de développement descendantes, orientées sur l’aide, les débats portent à présent davantage sur la fourniture de biens et de services rentables à la base de la pyramide économique (BOP, comme le font les entreprises de téléphonie mobile. Des équipes de recherche du CEMS (Centre for Emerging Markets Solutions  ont découvert que, bien qu’il soit possible de desservir de façon rentable les marchés BOP, cela exige de s’écarter des stratégies préconisées dans les publications ordinaires sur la BOP. Cette approche oblige notamment à aborder des questions liées au climat macroéconomique et commercial du pays, aux erreurs d’appréciation du risque, à l’esprit d’entreprise. Elle implique également une réorientation, afin de s'éloigner des multinationales et de se rapprocher du secteur des petites entreprises, avec les coûts de transaction qui le minent. Ce document examine également quelques modèles d’entreprise durables qui ont fonctionné sur ces marchés et analyse quelques secteurs que les capitaux commerciaux trouveront extrêmement intéressants et dignes d’investissements. Enfin, nous étudierons comment structurer et exploiter les énormes opportunités commerciales générées par le traitement du manque d'organisation des marchés BOP, à l’aide d’une combinaison de modèles d’entreprise innovants (en particulier autour de structures à coût réduit, de recherche, d’esprit d’entreprise et de capitaux patients.

    1999-05-01

    Full Text Available The dramatic impact of Electronic Commerce (EC is attracting much attention, most of which is directed towards emerging Internet technology. However, it is generally acknowledged that it will take a few more years before EC becomes mainstream. The perceptions of business students, the future business leaders, on the promises and perils of EC are therefore vital. Our research indicated that they believe that the capabilities of the Internet for marketing and distribution are achieved to a greater extent than those for accounting and finance. The use of digital money appears to be still unrealistic in their opinion. Their main concern is for the insecurity of EC in such areas as computer viruses, theft of information, and unauthorised access to data by intruders. As a consequence, the trust the students currently have in EC is relatively low. However, they are optimistic about future prospects of EC, which they perceive will significantly improve over the next few years.

    pressure, occasioned by additional elements with high vapour pressure, put on the formation of the hole. Micrographs made with welded parts of different metals show melting segregations similar to those obtained when filling a mould of great length. One may point out, that the geometrical configuration adopted by these segregations confirm the hypothesis of the metal flow, as previously contemplated. The study of these segregations, observed during examination through an interferential contrast microscope, has been attempted with a Castaing probe and by radiographical inspection of thin plates: no heterogeneity whatever has been observed. Mechanical tests operated on welded parts, did not show any appreciable difference existing between failure, elongation, yield point and impact values of a welded piece and those of a piece of the basic metal. This method applied on stainless steel shows not only excellent results, but also that the number of calories provided per length unit increases slightly with the welded thickness, whereas one could have expected a linear expression. Results obtained during this work, allow us to sift a certain number of data inherent to the electron beam welding, and to reflect on the definition of welding parameters versus aim to be reached.

    Jokipii and Meyer have recently obtained an electron density energy spectrum of the cosmic rays, originating in the Galaxy, using integral solutions of the steady state transfer equations, by considering a circular cylindric galactic disc as source and approximating the resulting fourth order integral. In this report, we present general results, obtained by using an arbitrary circular cylindric source, without restricting ourselves to the galactic disc. The integrals are treated exactly. The conclusions of Jokipii and Meyer form special cases of these results. We also obtain an exponential energy variation which, at the moment, is not observed experimentally. The second part of this work deals with more complicated, but perhaps more realistic models of elliptic cylindric and ellipsoidal galactic disc sources. One may also note that a very large source concentrated in a very small region gives a spectrum not unlike that for a small source distributed throughout a large volume. Finally, it may be remarked that the model adopted is much less restrictive than the artificial conception of 'leakage time' followed by other workers.

    Full Text Available Globalization of production and increasing competition spurs greater business use of innovative information systems. As globalization extends its reach over cities and regions, the positions of those places within the emerging global paradigms of regional economies is changing. Only those regions and cities that can mobilize assets for local advantage would succeed. This research examines the implications of location for electronic commerce (EC role in firm operations through the lens of managerial perceptions of EC systems, EC activities, agglomeration economies, firm-specific features and outputs relative to industry. The input-based view and industrial development frameworks provide the theoretical underpinning for this research. Fully completed instruments from 106 firms in Singapore and Lagos financial services sector, respectively, are the basis of our analysis. Our findings reveal varying results between industries across the two cities, supporting our propositions. Firms with well-configured EC systems are more likely to experience efficiency in EC activities and outputs, given conducive operational conditions. However, firm-specific features were not linked to output, a finding inconsistent with prior studies. Finally, EC business models that focus on operational efficiency strongly complement the historically relevant location variable in industrial operations. These findings provide basis for recommendations to policymakers, practitioners, and researchers.

    Nous presentons une etude des fluctuations magnetiques de la phase normale de l'oxyde de cuivre supraconducteur La_{2-x}Sr _{x}CuO_4 . Le compose est modelise par le Hamiltonien de Hubbard bidimensionnel avec un terme de saut vers les deuxiemes voisins (modele tt'U). Le modele est etudie en utilisant l'approximation de la GRPA (Generalized Random Phase Approximation) et en incluant les effets de la renormalisation de l'interaction de Hubbard par les diagrammes de Brueckner-Kanamori. Dans l'approche presentee dans ce travail, les maximums du facteur de structure magnetique observes par les experiences de diffusion de neutrons sont associes aux anomalies 2k _{F} de reseau du facteur de structure des gaz d'electrons bidimensionnels sans interaction. Ces anomalies proviennent de la diffusion entre particules situees a des points de la surface de Fermi ou les vitesses de Fermi sont tangentes, et conduisent a des divergences dont la nature depend de la geometrie de la surface de Fermi au voisinage de ces points. Ces resultats sont ensuite appliques au modele tt'U, dont le modele de Hubbard usuel tU est un cas particulier. Dans la majorite des cas, les interactions ne determinent pas la position des maximums du facteur de structure. Le role de l'interaction est d'augmenter l'intensite des structures du facteur de structure magnetique associees a l'instabilite magnetique du systeme. Ces structures sont souvent deja presentes dans la partie imaginaire de la susceptibilite sans interaction. Le rapport d'intensite entre les maximums absolus et les autres structures du facteur de structure magnetique permet de determiner le rapport U_ {rn}/U_{c} qui mesure la proximite d'une instabilite magnetique. Le diagramme de phase est ensuite etudie afin de delimiter la plage de validite de l'approximation. Apres avoir discute des modes collectifs et de l'effet d'une partie imaginaire non-nulle de la self-energie, l'origine de l'echelle d'energie des fluctuations magnetiques est examinee

    1995-12-19

    The goal of this thesis is the study of fast electron dynamics by means of the hard X-ray diagnosis installed in TORE SUPRA and numerical simulations. Fast electrons are generated in the plasma in the presence of the injected lower hybrid (LH) waves. Two aspects are studied in detail: the lower hybrid wave propagation and absorption in a periodically perturbed media and 2-D Fokker-Planck modelling of the fast electron dynamics in the presence of the LH power. Ripple effects on lower hybrid wave propagation and absorption are investigated using the ray tracing technique. A cylindrical equilibrium is first studied and a strong modification of the ray dynamics is predicted. Calculations are carried out in a real toroidal geometry corresponding to TORE SUPRA. It is shown that the lack of toroidal axisymmetry of the magnetic field may result in a modification of the ray evolution even if the global ray evolution is governed by the larger poloidal inhomogeneity. Simulation of LH experiments are performed for TORE SUPRA tokamak which has a large magnetic ripple (7% at the plasma edge). By considering ripple perturbation in LH current drive simulations, a better agreement is found with experimental results, in particular with the hard-X spectra and the current density profiles. In the second part of the thesis, a 2-D modeling of the fast electron dynamics in the velocity phase space is considered, based on the 2-D relativistic electron Fokker-Planck equation. Electron distribution functions obtained are used to calculate non-thermal Bremsstrahlung emission for different TORE SUPRA shots in a wide range of experimental conditions.

    From a theoretical point of view, a tensorial formalism adapted to the study of molecules or octahedral ions with a half-integer angular momentum has been developed for the first time. We have used here the method of projective representations, more consistent than that of double groups. A complete set of coupling coefficients and formulas, as well as the corresponding computing programs have been elaborated. This has firstly allowed us to write a simple model describing the vibronic structure of colored hexafluorides. Then, some applications of this formalism to the study of ro-vibronic couplings of XY{sub 6} molecules in a fourfold degenerate electronic state have been considered, especially concerning operators associated to dynamic Jahn-Teller effect. From an experimental point of view, we have considered IrF{sub 6}, for which we have mastered the synthesis, purification and conservation processes. A first study at low resolution (absorption and Raman scattering) has been performed for this molecule. We have then set up two high resolution spectroscopic devices in the visible region (saturated absorption - tested with an iodine cell- and simple absorption with multiple pass). These especially use a dye laser. They should now allow the spectroscopy of the visible band of IrF{sub 6} in order to resolve for the first time its fine rotational structure. (author)

    From a theoretical point of view, a tensorial formalism adapted to the study of molecules or octahedral ions with a half-integer angular momentum has been developed for the first time. We have used here the method of projective representations, more consistent than that of double groups. A complete set of coupling coefficients and formulas, as well as the corresponding computing programs have been elaborated. This has firstly allowed us to write a simple model describing the vibronic structure of colored hexafluorides. Then, some applications of this formalism to the study of ro-vibronic couplings of XY{sub 6} molecules in a fourfold degenerate electronic state have been considered, especially concerning operators associated to dynamic Jahn-Teller effect. From an experimental point of view, we have considered IrF{sub 6}, for which we have mastered the synthesis, purification and conservation processes. A first study at low resolution (absorption and Raman scattering) has been performed for this molecule. We have then set up two high resolution spectroscopic devices in the visible region (saturated absorption - tested with an iodine cell- and simple absorption with multiple pass). These especially use a dye laser. They should now allow the spectroscopy of the visible band of IrF{sub 6} in order to resolve for the first time its fine rotational structure. (author)

    The authors consider in this report the effects of high-energy electrons on rabbit teguments and on the underlying tissues after a single high dose irradiation. After briefly considering the mechanism of interaction between the electrons and matter as a function of their energy, the authors describe the dosimetry carried out, as a function of the irradiation device. The animal received surface doses of 5700 to 22100 rads in the thigh; the electron energy varied from 21 to 30 MeV. A clinical study was carried out over a period of nine months with a view to following the evolution of the damage and the functional degradation of the underlying tissues. A histological study of the induced damage was made after a second irradiation using 30 MeV electrons to produce doses of 16400 rads. Interesting observations were made concerning the damage caused to muscular and nerve tissues. (authors) [French] Les auteurs etudient, dans ce rapport, les effets des electrons de haute energie sur les teguments du lapin et les tissus sous-jacents apres une irradiation unique a dose elevee. Apres un rappel du mecanisme de l'interaction des electrons avec la matiere en fonction de leur energie, la dosimetrie realisee est exposee en fonction du dispositif d'irradiation. Les animaux ont recu, au niveau de la cuisse, des doses en surface de 5700 a 22100 rads; les energies des electrons vont de 21 a 30 MeV. Une etude clinique des lesions, observees pendant 9 mois, decrit leur evolution ainsi que les alterations fonctionnelles des tissus sous-jacents. Une etude histologique des lesions induites a ete realisee au cours d'une seconde experience pour des doses de 16400 rads avec des electrons de 30 MeV.

    After a short account of the experimental techniques employed in our studies, the experimental results obtained on pure nickel samples are exposed. The apparition of the successive annihilation stages of point defects created by electron bombardment is established by isochronal heat treatments: the annihilation kinetics and the corresponding activation energies are determined. The effect of the incident particle doses is also studied. The experimental results are then compared with R.A. Johnson's theoretical calculations of the stability and the migration of point defects in nickel, and taking into account the results obtained by Peretto in magnetic after effect measurements. This leads us to a model in good agreement with calculations and experiment for the first stages. In a second chapter the behaviour of nickel doped by certain impurities is studied. First, the results concerning the rate of increase of resistivity (function of sample purity) is investigated. Two possible explanations of the observed phenomenon are proposed: either a deviation with respect to Mathiessen's law, or an increase of the number of defects formed in the presence of impurity atoms. Finally, a study of the resistivity recovery of the doped samples permits us to suggest an order of magnitude for the binding energy interstitial/impurity atom in the nickel matrix. (author) [French] Apres avoir brievement rappele les techniques experimentales que nous avons utilisees pour cette etude, nous exposons les resultats experimentaux obtenus sur des echantillons de nickel pur. Les stades successifs d'annihilation des defauts ponctuels crees par bombardement electronique sont mis en evidence par traitements thermiques isochrones; les cinetiques de disparition, et les energies d'activation correspondantes sont determinees. Nous etudions egalement l'effet de la dose des particules incidentes. Les resultats experimentaux sont ensuite compares avec les calculs theoriques de R.A JOHNSON sur la stabilite

    This paper identifies three essential factors (information infrastructure, executive information system and a new manufacturing paradigm) that are used to support the development of a new business model for competitiveness. They facilitate changes in organization structure in support of business transformation. A SME can source a good manufacturing practice using a model of academic-university collaboration to gain competitive advantage in the e-business world. The collaboration facilitates the change agents to use information systems development as a vehicle to increase the capability of executives in using information and knowledge management to gain higher responsiveness and customer satisfaction. The case company is used to illustrate the application of a web-based executive information system to interface internal communications with external operation. It explains where a good manufacturing practice may be re-applied by other SMEs to acquire skills as a learning organization grows in an extended enterprise setting.

    Vacancy clustering in quenched magnesium has been studied by transmission electron microscopy. The nature of the vacancy loops observed, seems to depend essentially on the impurity content of the metal; this effect can be attributed to a variation of the stacking fault energy of magnesium due to impurities. (authors) [French] On a etudie par microscopie electronique en transmission les defauts crees par trempe dans le magnesium. Un effet considerable des impuretes du metal sur la nature des boucles obtenues par condensation de lacunes a ete mis en evidence; cet effet semble s'expliquer de facon satisfaisante par un abaissement de l'energie de faute d'empilement du magnesium du aux impuretes.

  17. Mesure de la Polarisation des Lambda Produits dans les Collisions Positron-Electron AU Lep a L'aide du Detecteur Opal

    Vandenplas, Denis

    Le Modele Standard est le cadre theorique general qui, jusqu'a present, a permis l'interpretation de tous les resultats experimentaux en physique des hautes energies. Cette theorie decrit, entre autres, la production d'une paire de particules elementaires, formee d'un quark et d'un antiquark, a partir de la desintegration de l'un des bosons mediateurs de l'interaction faible, le Z^0. Cependant, dans ce cas precis, la transformation subsequente des quarks primaires en particules reelles, un processus appele hadronisation, n'est decrite qu'a l'aide de modeles phenomenologiques. Afin de sonder les mecanismes de l'hadronisation, cette these presente la mesure du transfert du spin d'un quark etrange primaire a une particule appelee Lambda lors des desintegrations hadroniques du Z^0. L'etude a ete realisee dans le cadre de la collaboration OPAL, une des quatre experiences menees au collisionneur LEP, la ou des electrons et des positrons sont acceleres jusqu'a une energie commune, sqrt{s} = {rm E_ {cm}}, voisine de l'energie de production du rm Z^0, M_{Z ^0} egale a 91.3 GeV. La theorie electrofaible precise la direction du spin, c'est-a-dire la polarisation, d'un quark etrange primaire provenant de la desintegration d'un Z ^0. Quant a lui, le modele des quarks etablit que l'orientation du spin d'un Lambda est directement reliee a la polarisation du quark etrange dont il provient. La question est de determiner dans quelle mesure la polarisation du quark primaire est transmise au Lambda a la suite du processus de l'hadronisation, decrit dans le cadre de la ChromoDynamique Quantique. Une estimation, qui tient compte de tous ces differents aspects theoriques, evalue a 30% la polarisation des Lambda dont l'impulsion est superieure a 15 GeV/c. La mesure experimentale de la polarisation repose sur l'identification des Lambda a partir de la reconstitution de la desintegration Lambdato ppi^-. Ce processus, qui se deroule par le biais de l'interaction faible, viole la parite car

    Full Text Available There is a pressing need to understand the challenges surrounding procurement of and business case development for hospital electronic prescribing systems, and to identify possible strategies to enhance the efficiency of these processes in order to assist strategic decision making.We organized eight multi-disciplinary round-table discussions in the United Kingdom. Participants included policy makers, representatives from hospitals, system developers, academics, and patients. Each discussion was digitally audio-recorded, transcribed verbatim and, together with accompanying field notes, analyzed thematically with NVivo9.We drew on data from 17 participants (approximately eight per roundtable, six hours of discussion, and 15 pages of field notes. Key challenges included silo planning with systems not being considered as part of an integrated organizational information technology strategy, lack of opportunity for interactions between customers and potential suppliers, lack of support for hospitals in choosing appropriate systems, difficulty of balancing structured planning with flexibility, and the on-going challenge of distinguishing "wants" and aspirations from organizational "needs".Development of business cases for major investments in information technology does not take place in an organizational vacuum. Building on previously identified potentially transferable dimensions to the development and execution of business cases surrounding measurements of costs/benefits and risk management, we have identified additional components relevant to ePrescribing systems. These include: considerations surrounding strategic context, case for change and objectives, future service requirements and options appraisal, capital and revenue implications, timescale and deliverability, and risk analysis and management.

    With a view to explaining the formation of the final products resulting from the photolysis and the radiolysis of nitro-alkanes, we have attempted to identify the paramagnetic species formed as intermediates during the radiolysis. Our work has covered the structure and the reactivity of the radicals formed by 7 irradiation of the nitrogen containing derivatives at 77 K, and on the mechanism of formation and of disappearance of these radicals in the various matrices used. The radicals resulting from the removal of a hydrogen atom in the {alpha} position of the NO{sub 2} group, and the radicals resulting from addition reactions on the nitrogen group characterized by an unpaired electron on the nitrogen have been identified, either during the radiolysis of pure nitroalkanes, or during the radiolysis of nitro-alkanes in solution in organic glasses at 77 K. A study has been made of the conformation and the movements of radicals in the matrices, and the mechanism of formation of the observed radicals produced generally by the capture by the nitro-alkanes of primary radiolysis species. The nitro-alkanes in ethanol solution can behave as traps both for electrons and for free radicals. The study of the radiolysis of nitro-alkanes in solution in a polar ethanol glass has been completed with chemical analyses on the final radiolysis products; it has been possible to deduce the capture efficiency of trapped electrons and of free radicals by nitro-alkanes in ethanol. For this we have determined the radio-chemical yields of hydrogen, acetaldehyde and glycol as a function of the capture agent concentration, for the nitro-methane-ethanol system. A mechanism for the disappearance of the observed radicals is proposed.

    As reported previously, the scintillation pulse shape, which is characteristic of the excitating particle type (electron, proton, alpha, etc.), can be converted into a pulse-height independent parameter. This displays, by means of a multichannel analyser, the composition of a mixed particle beam which excites the scintillator. This method was successful with several scintillators, both of the organic and the inorganic type. Details are given of the electronic techniques used for converting the pulse shapes. For the simpler case of discrimination between only two classes of pulses (e.g. neutron-gamma discrimination) the use of passive networks has also been considered possible for further improvements and simplifications. A few networks were tried, the main results being that, in the presence of gamma background, the discrimination of recoil protons in liquid scintillators was extended to small pulses of a few decades of photoelectrons and the discrimination of neutron-capture fragments in boronloaded liquids was obtained. Some of these networks operated with pulses of the same polarity, from two of the last dynode, or even with the output from a single electrode. This may be useful when it is convenient to use the anode independently, e. g. for operating fast time circuits.

    A study of the point defects formed in cobalt by electron bombardment is presented. The results are compared with those previously obtained for two other ferromagnetic metals of different structure, iron and nickel. In the first part we give a review of the literature concerning the creation of point defects, their contribution to resistivity and their annihilation mode in the three structure types. We then describe the experimental techniques adapted, in particular the study of the resistivity increase during a linear temperature rise. Our investigations concern the following, essential points : the observation of the successive annihilation stages of the point defects formed in pure cobalt, a study of the variations with respect to the doses and energy of the incident particles, and the determination of the annealing kinetics and the corresponding activation energies. The results are finally compared with the various models of point defect annihilation proposed for other metals: none of these interpretations is in perfect agreement with our results. In the case of cobalt we are thus led to modify the model proposed by our laboratory for iron an nickel. The difference between these three metals is explained by the anisotropic character of the cobalt matrix.

    Based on findings from earlier studies which showed that links to academic web sites contain important information, the following study examines the practicability of using co-link data to describe cooperation and competition in optoelec-tronic business. The analysis was based on 32 companies and organizations which were found in an issue of a specialist magazine. For the purpose of the research three search engines - Google, Yahoo! and MSN Search were used. Assuming that a number of co-links to a pair of Web sites is a measure of the similarity between the two companies, the study aims at search for the sets of companies that would be similar to one another. The method applied is the MDS - multidimensional scaling that allows to present results of the analysis on a 2D map.

(author) [French] Comme le predit la theorie harmonique, le spectre de la diffusion inelastique coherente de neutrons par un monocristal non conducteur, pour un angle de diffusion donne, se compose d'une serie de pics de fonction delta, qui se superposent a un bruit de fond continu. Les pics correspondent a des phenomenes a un phonon, dans lesquels un phonon est absorbe ou emis par le neutron; le bruit de fond provient de phenomenes a plusieurs phonons. Lorsqu'il existe des forces anharmoniques (interaction phonon-phonon) les pics de fonction delta s'elargissent pour former des pics finis et leur frequence centrale est dephasee par rapport aux valeurs harmoniques. Dans le cas d'un metal il y a, en plus des interactions phonon-phonon, une interaction entre les phonons et les electrons de conduction, laquelle contribue a dephaser et elargir encore davantage les pics a un phonon. Continuant les travaux de Van Hove (qui avait considere le cas relativement simple d'un cristal non conducteur a l'etat fondamental, soit T = 0{sup o}K) l'auteut a etudie les deplacements et les largeurs des pics de diffusion resultant des interactions indiquees plus haut, a l'aide de la theorie de la perturbation a plusieurs particules, en ayant largement recours a la methode des diagrammes. Il admet, avant tout examen du probleme, que quelle que soit la force des interactions, la largeur de chaque pic est petite par rapport a la valeur de la frequence en son centres dans ces conditions seulement, on peut considerer que les pics sont bien definis par rapport au bruit de fond, si les calculs d'interaction sont pousses jusqu'aux ordres superieurs. On estime que cette hipothbse est realisee tant que les temperatures ne sont pas trop elevees et que les valeurs du vecteur d'onde des phonons ne sont pas trop considerables. La methode

    Commercially available one- and two-lamp fluorescent luminaires were tested, and a number of electrical parameters were measured using varying combinations of lamps and either iron-core or electronic ballasts. Comprehensive photometric tests and thermal measurements were also conducted. The test results were tabulated and compared. The performance of the iron-core ballasts was found to be sufficiently close to nominally rated values to not raise concerns. Results from testing the electronic ballasts showed that the user has to be careful when selecting these ballasts, as they far exceed standard specification limits for current and voltage crest factors. All other electrical, photometric and thermal parameters are within accepted levels. An economic analysis was undertaken to determine cost benefits and payback periods for using electronic ballasts, the use of which will result in higher efficiency and lower power consumption. A project life of 20 years was assumed, and analysis was run for a power cost of $0.04/kWh. A unit made by Fyrnetics showed the lowest total annual owning and operating costs and had a payback period of 12.1 years. 13 figs., 13 tabs.

    Customers of the RES GmbH current inverter producer complained about disturbances, outages, and low yields. Now, the producer has filed for insolvency; business partners will probably lose their warranty claim and also their contact for repair and replacement parts. IPE, a partner fitter's company, even fears of going bankrupt too. All partners agree that in the future, they will limit their business activities to partners they know better. (orig.)

    excited these modes can radiate only if coupled to transverse waves; in zero-{beta} this coupling occurs at a surface or at a local inhomogeneity. Since a prominent effect of finite {beta} is to couple longitudinal and transverse waves, the spectrum and coupling of electron cyclotron oscillations is calculated for arbitrary {beta}.

A cette limite, le champ electrique perturbe est de nature electrostatique, et l'equation de Vlasov est remarquablement simplifiee.

    Full Text Available This research contributes to the understanding of how different practices of innovation management are related to mid- and long-term growth and profitability. Governments and regional development agencies invest relevant budgets to foster innovation in small and medium enterprises (SMEs and improve their innovation management practices to make them more competitive. Nevertheless, it is not clear what impact these practices have on a company's performance over a long period of time. We propose a model to audit and classify innovation practices and empirically test the impact of innovation practices on the firms’ long–term financial performance, using a broad sample of companies in the electronics sector. Our empirical results show that, within a regional context, companies that are similar in terms of size, position in the value chain, and ownership structure follow similar innovative practices. Furthermore, the use of a systematic approach for innovation leads to revenue growth but does not necessarily increase profit or productivity.

    During a pilot production run, about 1.200 kg of uranium carbide cylindrical rods were prepared by electron bombardment fusion and continuous casting in an apparatus making it possible to operate in a constant vacuum automatically. In order to make the most of the fusion technique used, it was necessary to resolve a certain number of problems involved in this production. It was found that the energy yield for the electron bombardment heating using accelerating voltages of about 10 kV was 100 per cent; about 40 per cent of the electrons are re-emitted by back-scattering. These electrons leave the surface with practically zero energy. The fusion technique leads to the elimination of the majority of the metallic impurities. In order to explain the variations in the non-metallic impurity contents the different reactions occurring in the molten uranium monocarbide have been determined. A micrographic study of the rods obtained has shown various types of crystallization depending on the rate of casting and, despite the uniaxial symmetry of the cooling, no texture has been observed, whatever the rate of fusion employed. The aspects of the fracture surfaces observed on certain rods can be explained by theory in the domain where the material is elastic. Furthermore it has been shown that a decrease in the brittleness occurs as a result of the formation of fine precipitates of the Wiedmanstatten structure type.

It shows methodological framework for development of e-services, through use of RUP (Rational Unified Process methodology. The Unified Modelling Language (UML notation was used for description of the system model. The paper presents modeling of the process of marketing of medications for human use, as well as development of the information subsystem underpinning it. The analysis of the marketing of medications in Serbia was carried out in 2006, 2007, 2008 and 2009, by the Medicines and Medical Devices Agency of Serbia, which was authorized to collect and analyze data on the marketing and consumption of medicines and medical devices. Data gathered for a particular time period were analyzed using Anatomical Therapeutic Chemical Classification and the Defined Daily Doses methodology. The amount of medicines consumed was translated into the DDD by 1000 individuals per day, and gave an insight into the number of individuals (out of 1000 who used the medicine under observation and were under its effect during a single day. The data extracted are correlated with the number of individuals who took the medication during the period under observation. In the year 2006 total marketing of medications for human use amounted to € 510.833.609,54, in 2007 it stood at € 687.588.174,80, in 2008 it was € 799.082.221,05, while the overall marketing of medicines in the year 2009 was € 741.981.960,19. By processing the data by methodology of DDD, the following results were obtained: 1013,70 DDD/1000 individuals/day in year 2006; in year 2007, 1084,34 DDD/1000 individuals/day; in year 2008, 1219,57 DDD/1000 individuals/day and in year 2009, 1177,72 DDD/1000 individuals/day.

    The runaway electron effect is considered in different fields: nuclear fusion, or the heating of the solar corona. In this thesis, we are interested in runaway electrons in the ionosphere. We consider the issue of electrons moving through an ionospheric gas of positive ions and neutrals under the influence of a parallel electric field. We develop a kinetic model of collisions including electrons/electrons, electrons/ions and electrons/neutrals collisions. We use a Fokker-Planck approach to describe binary collisions between charged particles with a long-range interaction. A computational example is given illustrating the approach to equilibrium and the impact of the different terms. Then, a static electric field is applied in a new sample run. In this run, the electrons move in the z direction, parallel to the electric field. The first results show that all the electron distribution functions are non-Maxwellian. Furthermore, runaway electrons can carry a significant part of the total current density up to 20% of the total current density. Nevertheless, we note that the divergence free of the current density is not conserved. We introduce major changes in order to take into account the variation of the different moments of the ion distribution functions. We observe that the electron distribution functions are still non-Maxwellian. Runaway electrons are created and carry the current density. The core distribution stay at rest. As these electrons undergo less collisions, they increase the plasma conductivity. We make a parametric study. We fit the electron distribution function by two Maxwellian. We show that the time to reach the maximal current density is a key point. Thus, when we increase this time, we modify the temperatures. The current density plays a primary role. When the current density increases, all the moments of the distributions increase: electron density and mean velocity of the suprathermal distribution and the electron temperature of the core and

    The main part of this thesis is devoted to an experimental study by transmission electron microscopy of the different phases of the superconducting bismuth cuprates Bi{sub 2}Sr{sub 2}Ca{sub n-1}Cu{sub n}O{sub 2n+4}. In high resolution electron microscopy, the two types of incommensurate modulation realized in these compounds have been observed. A model of structure has been proposed from which the simulated images obtained are consistent with observations. The medium resolution images correlated with the electron diffraction data have revealed existence of a multi-soliton regime with latent lock in phases of commensurate periods between 4b and 10b. At last, a description of different phases of these compounds as a result of superstructures from a disordered perovskite type structure is proposed (author) [French] Le travail presente dans cette these consiste en une etude experimentale essentiellement par microscopie electronique en transmission des differentes phases supraconductrices presentes dans les composes appartenant a la famille des cuprates de bismuth Bi{sub 2}Sr{sub 2}Ca{sub n-1}Cu{sub n}O{sub 2n+4}. Les obsevations de microscopie electronique a haute resolution ont permis de mettre en evidence les differentes modulations incommensurables realisees dans ces composes. Un modele de structure est propose et a permis d'obtenir des images simulees compatibles avec les observations. D'autre part, les observations de microscopie electronique en moyenne resolution sur ces composes, combinees avec les resultats de diffraction electronique, ont montre l'existence d'un regime multisoliton associe a des phases de Lock-in latentes de parametres compris entre 4b et 10b.

The irradiated animals displayed the same general symptoms as those produced by X - or gamma-rays. The biological tests did not bring to light any particular phenomenon which can be considered as characteristic of these high-energy particles. As determined in four tests (LD{sub 50}, average expectation of life and diminution of thymus and testicles), the RBE is close to 1. This corresponds to the mean LET of the particles and, in the case of the protons, does not appear to be increased by the higher local LET of the spallation fragments.

Indeed, following the World Solar Summit in Harare in 1997, UNESCO, the European Commission, ADEME and ICAEN have taken the initiative to organize a series of Business Forums devoted to renewable energies. The first two were held in Quito in 1998 and in Harare in 1999. The Harare forum was especially devoted to the use of renewable energies in decentralized rural electrification. Promoters wish to focus debates and thinking on themes with a particular bearing on surrounding countries. This is why the main subject for this Forum is how renewable energies can be used for a sustainable development in the Arab region, supplying energy and water. The growing demand for water is a crucial issue in Middle Eastern and Mediterranean countries. The relatively limited resources, the high population growth and the regular improvement in the standard of living can, in the medium term, only confirm the attention that should be given to the problem. Firstly, it is a question of identifying the most efficient and best-adapted technologies, and enabling their dissemination, all the while developing the know-how of local operators. It is also a matter of focusing on the problems connected with the financing of the projects. Indeed, public aid for development can be sought on both sides, and international financing can be mobilized at the World Bank, within the Global Environmental Facility, or through development banks, although access to them still seems difficult. How can we simplify these procedures and at the same time meet the necessary guarantees, and what are the most efficient financing mechanisms? Lastly, to implement these projects it is vital that we increase commercial opportunities and favour the bringing together of all the players present here today - the users, and the public and private sectors.

    Inelastic X-ray scattering (IXS) and associated methods has turn out to be a powerful alternative for high-pressure physics. It is an all-photon technique fully compatible with high-pressure environments and applicable to a vast range of materials. Standard focalization of X-ray in the range of 100 microns is typical of the sample size in the pressure cell. Our main aim is to provide an overview of experimental results obtained by IXS under high pressure in 2 classes of materials which have been at the origin of the renewal of condensed matter physics: strongly correlated transition metal oxides and rare-earth compounds. Under pressure, d and f-electron materials show behaviors far more complex that what would be expected from a simplistic band picture of electron delocalization. These spectroscopic studies have revealed unusual phenomena in the electronic degrees of freedom, brought up by the increased density, the changes in the charge-carrier concentration, the over-lapping between orbitals, and hybridization under high pressure conditions. Particularly we discuss about pressure induced magnetic collapse and metal-insulator transitions in 3d compounds and valence fluctuations phenomena in 4f and 5f compounds. Thanks to its superior penetration depth, chemical selectivity and resonant enhancement, resonant inelastic X-ray scattering has appeared extremely well suited to high pressure physics in strongly correlated materials.

    The quasi-equilibrium theory has been applied only to the family of long chain aliphatic hydrocarbons. We have tried to extend it to phenanthrene and methyl-phenanthrenes molecules, i.e. to aromatic molecules possessing a great number of degrees of freedom. In a first part, we have attempted to give a method of interpretation of the ionization and dissociation processes of the phenanthrenic molecules. These preliminary experimental studies of the behaviour under electron impact of the compounds provide us a great wealth of information about important structural transformations of the molecular and fragment ions, and also about auto-ionization and excitation processes of the studied molecules. The experimental study of the metastable peaks has then confirmed the validity of the preceding dissociation processes, while it gave with more accuracy some thermodynamical values in connection with decomposition reactions. The three studies of the ionization, then dissociation processes and of the metastable peaks, represent the three phases of a general method of interpretation of the fragmentation in mass spectrometry. In order to give this method a theoretical basis, we have carried out the molecular diagrams of each of the studied, compounds, showing by this way the aid of Quantum Mechanics to the study of excited and ionic states. In a second part, we have carried out the mass spectra of the phenanthrene and methyl-phenanthrenes molecules by means of the rate constants expression given by ROSENSTOCK. We have proposed new methods of calculation of the frequency factors, for the aliphatic molecules as well as the aromatic ones. If the rather good agreement observed between the experimental and calculated results cannot be surely attributed to the validity of the theory, however it out-lines the interest presented by the application of this theory to large aromatic molecules. Furthermore, the results at which we arrived provide us with interesting information about the

    The Electronic Health Records for Clinical Research (EHR4CR) technological platform has been developed to enable the trustworthy reuse of hospital electronic health records data for clinical research. The EHR4CR platform can enhance and speed up clinical research scenarios: protocol feasibility assessment, patient identification for recruitment in clinical trials, and clinical data exchange, including for reporting serious adverse events. Our objective was to seed a multi-stakeholder ecosystem to enable the scalable exploitation of the EHR4CR platform in Europe, and to assess its economic sustainability. Market analyses were conducted by a multidisciplinary task force to define an EHR4CR emerging ecosystem and multi-stakeholder value chain. This involved mapping stakeholder groups and defining their unmet needs, incentives, potential barriers for adopting innovative solutions, roles and interdependencies. A comprehensive business model, value propositions, and sustainability strategies were developed accordingly. Using simulation modelling (including Monte Carlo simulations) and a 5-year horizon, the potential financial outcomes of the business model were forecasted from the perspective of an EHR4CR service provider. A business ecosystem was defined to leverage the EHR4CR multi-stakeholder value chain. Value propositions were developed describing the expected benefits of EHR4CR solutions for all stakeholders. From an EHR4CR service provider's viewpoint, the business model simulation estimated that a profitability ratio of up to 1.8 could be achieved at year 1, with potential for growth in subsequent years depending on projected market uptake. By enhancing and speeding up existing processes, EHR4CR solutions promise to transform the clinical research landscape. The ecosystem defined provides the organisational framework for optimising the value and benefits for all stakeholders involved, in a sustainable manner. Our study suggests that the exploitation of EHR4CR

    The goal of this work is to improve our knowledge on the actinide-ligand bond properties. To this end, the hexacyanoferrate entities have been used as pre-organized ligand. We have synthesized, using mild chemistry, the following series of complexes: An{sup IV}[Fe{sup II}(CN){sub 6}].xH{sub 2}O (An = Th, U, Np, Pu); Am{sup III}[Fe{sup III}(CN){sub 6}].xH{sub 2}O; Pu {sup III}[Co{sup III}(CN){sub 6}].xH{sub 2}O and K(H?)An{sup III}[Fe{sup II}(CN){sub 6}].xH{sub 2}O (An = Pu, Am). The metal oxidation states have been obtained thanks to the {nu}{sub CN}, stretching vibration and to the actinide L{sub III} absorption edge studies. As Prussian Blue, the An{sup IV}[Fe{sup II}(CN){sub 6}].xH{sub 2}O (An = Np, Pu) are class II of Robin and Day compounds. X-ray Diffraction has shown besides that these complexes crystallize in the P6{sub 3}/m space group, as the isomorphic LaKFe(CN){sub 6}.4H{sub 2}O complex used as structural model. The EXAFS oscillations at the iron K edge and at the An L{sub III} edge allowed to determine the An-N, An-O, Fe-C and Fe-N distances. The display of the multiple scattering paths for both edges explains the actinide contribution absence at the iron edge, whereas the iron signature is present at the actinide edge. We have shown that the actinide coordination sphere in actinides hexa-cyanoferrates is comparable to the one of lanthanides. However, the actinides typical behavior towards the lanthanides is brought to the fore by the An{sup IV} versus Ln{sup III} ions presence in this family of complexes. Contrarily to the 4f electrons, the 5f electrons influence the electronic properties of the compounds of this family. However, the gap between the An-N and Ln-N distances towards the corresponding metals ionic radii do not show any covalence bond evolution between the actinide and lanthanide series. (author)

    The main electronic applications of superconductors involve the signal processing, the electromagnetic wave detection and the magnetometry. Characteristics of devices based on conventional superconductors cooled by liquid helium are given and the changes induced by incorporating high-temperature superconductors are estimated. After a survey of new superconductor properties, the superconducting devices for analog or digital signal processing are reviewed. The gains predicted for high-temperature superconducting analog devices are considered in greater detail. Different sections deal with the infrared or (sub)millimeter wave detection. The most sensitive apparatuses for magnetic measurements are based on SQUIDs. Features of SQUIDs made of granular high-temperature superconducting material samples (grain boundaries behave as barriers of intrinsic junctions) are discussed.

    Using the photo-voltaic effect in p-n junctions, we have studied, during bombardment, the mechanism of the recombination of 'electron-hole' pairs in the presence of structure defects produced in germanium of the N and P types by {gamma} rays from a Co{sup 60} source. At 310 K the level of the recombination centres is situated 0.25 eV above the conduction band and the capture cross-sections of the holes and of the electrons have the respective values of: {sigma}{sub p} = 4 X 10{sup -15} cm{sup 2} and {sigma}{sub n} = 3 X 10{sup -15} cm{sup 2}. The value of {sigma}{sub n} appears to be under-estimated because the number of defects in P-type samples appears to be lower than that in N-type samples. These results lead to the conclusion that the interstitials are responsible for the recombination. At 80 K it has been found that in N-type samples, a shallow level exists at O.05 eV below the conduction band with a capture cross-section for the holes of {sigma}{sub p} {>=} 10{sup -14} cm{sup 2}. We believe that in this case the recombination of charge carriers is controlled by the neighbouring 'defect-interstitial' pairs. In P-type samples at low temperature, the life-time is practically constant during irradiation. This fact is attributed to a spontaneous annealing of defects ol purely electrical origin. In the last part of the work the study of the photo-voltaic effect applied to the problem of gamma radiation dosimetry is considered. It is shown that such dosimeters, based on this principle, make it possible to measure the intensity of gamma rays over a very wide range.

    Full Text Available Characterizing pseudo oil base muds (POBM amounts to determining the relationships between the size distribution of droplets and stability of emulsions. Conventional scanning and transmission electron microscope (SEM and TEM have been used to investigate these problems. However, hydrated samples are difficult to handle using such techniques. The Environmental Scanning Electron Microscope (ESEM or Electroscan and the cryogenic techniques have opened the door to the study of wet and non-conductive specimens, and of various liquids or emulsions. ESEM with the cold stage allows us to directly visualize emulsions :- without any preparation or coating;- at different temperatures, by controlling the specimen temperature (between -180°C and -8O°C and pressure (between 400 and 1400 Pa. La caractérisation des boues de forage à base d'huile de substitution (POBM équivaut à définir la relation entre la répartition dimensionnelle des gouttelettes et la stabilité des émulsions. Les microscopes électroniques à balayage (SEM et à transmission (TEM classiques ont été utilisés pour étudier ces problèmes. Toutefois, les échantillons hydratés sont d'un traitement difficile à l'aide de ces techniques. Le microscope environnemental électronique à balayage (ESEM ou electroscan et les techniques cryogéniques ont ouvert la voie à l'étude de spécimens humides et non conducteurs, de liquides et d'émulsions divers. A froid, l'ESEM nous permet de visualiser des émulsions : - sans aucune préparation ou enrobage, - à différentes températures, en régulant la température (entre - 180°C et - 80°C et la pression (entre 400 et 1400 kPa du spécimen. Le présent document se propose de caractériser les boues à base d'huile de substitution et d'étudier : - l'homogénéité de la formulation et la procédure de préparation, - l'influence de la répartition dimensionnelle des gouttelettes sur la stabilité des émulsions.

    In the present report an expression is deduced for the spectral distribution of flux of over a few hundred electron volts; it is valid for most cases of thermal neutron reactors. This expression is: {psi}(E) = K [{psi}{sub o}(E) + h {psi}{sub e}(E)] {psi}{sub o}(E) is the so-called 'homogeneous' constituent of the flux; it corresponds approximately to the case of an infinite homogeneous medium; it is of the type: Y(V - E) e{sup (b{radical}}{sup E)}/E + Y(E-V) F E{sup {upsilon}} e{sup -{beta}}{sup E} The parameters V and F are such that {psi}{sub o}(E) and its derivative are continuous at the junction energy V. {psi}{sub e}(E) is the 'heterogeneous' constituent of the flux; it is of the type: E{sup {upsilon}} e{sup -{beta}}{sup E}. The various parameters of {psi}(E) are on the one hand characteristic of the nature of the reactor moderator, and on the other hand determined by a resonant flux measurement and one, or possibly two, measurements using a fast neutron threshold detector. We have been led furthermore to define an expression for the threshold reaction section which is more exact than the conventional transition function.

    The free radicals created by different radiations in glycine are measured by electron spin resonance and their number is evaluated in function of the absorbed dose. This number decreases when the LET of the radiations increases ; in other words,high LET radiations gives less radiochemical effects; in contrary with the fact that high LET radiations creates more damage in biological materials. The decreasing with time of the number of free radicals and the speed of this decrease is a function of temperature; by the study of the kinetics of this decrease, an attempt has been made to prove the presence of three radicals. (authors) [French] Les radicaux crees par divers rayonnements dans la glycine sont detectes par resonance paramagnetique electronique et leur nombre est evalue en fonction de la dose.

    The mechanism of recovery from acute radiation damage may be studied by using two types of radiations which show small differences in the acute RBE, and large differences of effect in the recovery phase. As observed in previous experiments, this condition is achieved by comparing the effects in mammals of 150 kVpX-rays and those of 15 MeV electrons produced by a betatron. The present paper presents the results of an autoradiographic study on the behaviour of single classes of cells of the mice thymus by use of tritiated thymidine as DNA precursor. Data are related to the modifications in distribution of the size categories of the cell population and to organ weight. After irradiation the large to small cell ratio is increased ; the incorporation of tritiated thymidine is reduced in large and in small lymphocytes. In the acute phase of effect, no significant differences between X-rays and electrons are observed in cell sizes and in labelling of large cells. A relative change appears in labelling of small cells, a fact that may have a relation with the RBE values of fast electrons, in agreement with the organ weight data. In the recovery, less differentiated cells show active proliferation, but the percentage of mature lymphocytes remains small. After exposure to 15 MeV electrons proliferative activity of large cells is greater, according to the time curves of the thymic atrophy. From the above results, regenerative potentiality appears related to the degree of damage on primitive cells; for a given dose, the latter appears larger after X-rays than after electrons.

    An investigation of the basic principles of contrast enhancement is presented. Certain fundamental laws should be observed in the design of transforming systems as well as in their application in order to visualize a maximum of information. These laws are developed using the following parameters and functions, which in general characterize all kinds of transforming systems: (1) The elementary cell of primary information, defined by time intervals or pre-selected number of counts etc; (2) The information-transforming function, according to which the elementary cell is represented in the scintigram (by the degree of blackening of a photo-dot, for example). Often this function is regarded as the final characteristic of the transforming system; this is true, however, only when statistical fluctuations are negligible. The behaviour of a transforming system including statistical fluctuations is described by the following functions, which show the quality of a scintigram in quantitative terms. (3) The picture-generating function, according to which the mean value of counting rate over an area is transformed into a mean blackening of the corresponding area in the scintigram. This function gives the contrast enhancement. (4) The significance function, which describes the loss of information caused by the transformation. This function gives the degree of regularity of representation. On the basis of the above definitions, the paper deals with the following problems: optimal ''size'' of the primary information cell, depending on the resolution of the detector; optimal shape of transforming function for various purposes; some electronic circuits for realization of such functions. In particular, an apparatus is described in detail which gives an optimum of linear presentation using a suitable selected non- linear transforming function. Thus the range of net counting rate between background and maximal counting rate is projected to the full range of blackening in the scintigram

  1. Third Party Services for Enabling Business-to-Business Interactions

    Shrivastava, Santosh

    Business-to-business (B2B) interactions concerned with the fulfilment of a given business function (e.g., order processing) requires business partners to exchange electronic business documents and to act on them. This activity can be viewed as the business partners taking part in the execution of a shared business process, where each partner is responsible for performing their part in the process. Naturally, business process executions at each partner must be coordinated at run-time to ensure that the partners are performing mutually consistent actions (e.g., the seller is not hipping a product when the corresponding order has been cancelled by the buyer). A number of factors combine to make the task of business process coordination surprisingly hard:

    Well-defined prompt gamma-rays, prompt-conversion elections and prompt K-X-rays have been observed in coincidence with moving fission fragments of Cf{sup 252}. In a few cases, the masses and charges of the nuclei emitting the gamma-rays and conversion electrons have been identified. The gamma-ray, prompt-electron and prompt X-ray energies as well as the two fission fragments energies were measured with high-resolution solid-state detectors. The masses of the fragments were deduced from their energies, and the nuclear charges were determined by measuring the K-X - ray energies associated with different masses. The magnitude and sign of the Doppler shift in gamma-ray energy allowed assignment of the gamma-ray lines to single members of fragment pairs. The Doppler shift also provides an independent measure of the fragment velocity and hence the fragment mass after neutron emission. The results of the X-ray measurements are consistent with the view that the majority of the prompt X-rays emitted during the spontaneous fission of Cf{sup 252} are the result of internal conversion during the de-excitation of low-energy collective states of the primary fission fragments. Apart from the specific results discussed above, the most important consequence of these experiments has been the demonstration that it is possible to study the properties of individual fission fragments, as identified by their characteristic radiations, rather than studying the properties of an average fission fragment with an average mass and charge. The consequences of this advance in the technique of studying fission fragments ate being explored.

    The secondary electron yield {gamma}-bar due to primary positive ions D{sup +} and D{sup +}{sub 2} has been measured in the 70 keV to 300 keV ion energy range. Several metallic targets have been used. The variation of this yield with the angle of incidence is proportional to sec {theta} where {theta} is the angle between the beam of primary ions and the normal to the target surface. The values {gamma}-bar decrease for increasing energy ions. At a given energy all the targets tried gave approximately the same electron yield.

  9. Theoretical and experimental studies on the improvement of the time structure of the extracted electron beam from the stretcher ring ELSA; Theoretische und experimentelle Untersuchungen zur Verbesserung der Zeitstruktur des extrahierten Elektronenstrahls aus dem Stretcherring ELSA

    Neckenig, M.

    1993-03-01

    The Electron Stretcher Accelerator ELSA of Bonn University is the first electron-pulse-stretcher-ring in the GeV-range. It delivers an external electron beam in the energy range from 500 MeV to 3.5 GeV, with a current between 10 pA and 100 nA, depending on the demands of the experiments. A synchrotron is used to preaccelerate the electrons to energies between 500 MeV and 1.8 GeV. In this energy-range, ELSA is used in the pure stretcher-mode, whereas for higher energies it is used as a post accelerator. For beam extraction, a third-integer resonance, driven by sextupoles, is applied. The problems, delimiting the duty-factor of the extracted beam in the pure stretcher-mode, have been investigated and solved. In this mode, duty-factors - measured by coincidence methods - of up to 55% have been reached, which are of the order of the theoretical limit for the applied extraction method of about 60%. (orig.) [Deutsch] Ziel dieser Arbeit war es, die Phaenomene, die das Tastverhaeltnis des aus ELSA extrahierten Strahles beeinflussen, zu verstehen. Aus dem gewonnenen Verstaendnis heraus sollten Massnahmen getroffen werden, um das Tastverhaeltnis zu verbessern. Die Effekte, die ein gutes Tastverhaeltnis in der Vergangenheit verhindert haben, waren in der Hauptsache ein Stromrippel in den Netzgeraeten der Hauptmagnete sowie die Extraktion aus dem Synchrotron, die nur eine schlechte Fuellung von ELSA erlaubte. Der Rippel wurde durch den Einbau von Filtern in die Netzgeraete behoben. Bei den gegenwaertigen Extraktionszeiten von 20 msec spielt der Rippel nur noch eine geringe Rolle. Die Extraktion aus dem Synchrotron wurde modifiziert, so dass ohne Beschaffung neuer Komponenten eine Verbesserung der ELSA-Fuellung von 40% auf maximal 75% moeglich wurde. Durch eine Reihe von Massnahmen konnte der Wert des Tastverhaeltnisses von 6%-7% kurz nach der Inbetriebnahme auf heute 50%-55% gesteigert werden. Die Extraktion kann durch ein einfaches Modell beschrieben werden, dass alle

    Resistivity and magnetic after effect (m.a.e.) measurements are used to study the influence of carbon atoms on the annealing process of point defects created by electron irradiation (3 MeV) at low temperature (20 deg. K). The presence of the carbon atoms has a strong influence on the recovery sub-stage I{sub E} and stage III. For the former, the carbon impurity traps the freely migrating iron interstitial. For the latter the effect is interpreted as being due to formation during annealing, of a carbon vacancy pair. A pronounced m.a.e. band is attributed to the reorientation of this carbon vacancy complex. All these results are coherent with the interpretation of a low temperature migrating free interstitial. (author) [French] L'influence des atomes de carbone sur le recuit des defauts ponctuels crees par irradiation electronique (3 MeV) a basse temperature (20 deg.

Cette influence se manifeste principalement au cours du sous stade I{sub E} et du stade III de resistivite. Au sous stade I{sub E} les atomes de carbone piegeraient les interstitiels libres de fer au cours de leur migration. Le stade III est interprete comme etant du a la recombinaison du carbone dans les lacunes. Une importante bande de tramage magnetique etant attribuee a la reorientation de ce complexe.

    Full Text Available Les mobilités pendulaires semblent être en augmentation en Europe depuis une dizaine d’années. Cette croissance du temps passé à se déplacer amène à remettre en question la conjecture de Zahavi et apparaît relativement inexplicable en regard du paradigme classique de l’acteur rationnel traditionnellement utilisé dans le champ des transports. Si, dans la littérature, les temps de déplacements sont principalement expliqués par le contexte résidentiel, la forme urbaine et le travail, ce cadre explicatif ne dit rien des processus de décision eux-mêmes qui amènent aux pendularités intensives.À partir d’une enquête qualitative menée auprès de pendulaires français, suisses et belges, cette contribution propose d’analyser les arbitrages et les éléments déterminants des processus de la grande pendularité. Les mobilités quotidiennes pendulaires apparaissent comme le résultat de compromis entre activité professionnelle, attachement résidentiel et choix de vie et prennent ainsi la forme de stratégies de conciliation entre vie privée et vie professionnelle. Ces mobilités spatiales permettent alors paradoxalement la préservation des ancrages résidentiels, sociaux et familiaux.Roots and wings. Long-distance commuting patterns, or how to conciliate professional and personal lifeLong-distance commuting patterns appear to be increasing in Europe over the last ten years. These raising mobility patterns lead to reappraise the Zahavi conjecture and appear largely inexplicable by the classical rational actor paradigm traditionally used in transportation research. In literature, commuting is mainly explained by residential contexts, urban forms and job. Nevertheless this theoretical frame says little about the decision-making processes themselves. Based on a qualitative survey conducted in three European countries - France, Belgium and Switzerland – among a population of high commuters, this paper proposes an analysis of

    Faudot, E

    2005-07-01

    This work investigates the problematic of hot spots induced by accelerated particle fluxes in tokamaks. It is shown that the polarization due to sheaths in the edge plasma in which an electron beam at a high level of energy is injected, can reach several hundreds volts and thus extend the deposition area. The notion of obstructed sheath is introduced and explains the acceleration of energy deposition by the decreasing of the sheath potential. Then, a 2-dimensional fluid modeling of flux tubes in front of ICRF antennae allows us to calculate the rectified potentials taking into account RF polarization currents transverse to magnetic field lines. The 2-dimensional fluid code designed validates the analytical results which show that the DC rectified potential is 50% greater with polarization currents than without. Finally, the simultaneous application of an electron beam and a RF potential reveals that the potentials due to each phenomenon are additives when RF potential is much greater than beam polarization. The density depletion of polarized flux tubes in 2-dimensional PIC (particles in cells) simulations is characterized but not yet explained. (author)

    Full Text Available Liberal commercial applications that spread all over the world lead to increase in international commercial activities and also cause changes in production and consumption patterns. Differences among countries’ development levels do not make much difference in countries’ overall economic purposes. While developed countries try to grow-up more, developing countries are willing to grow-up and develop at the same time. Achievement of this common goal depends on countries’ ability to increase their economic competitiveness. To improve the competitiveness of an economy in both domestic and foreign markets, no matter what their development levels are, is closely related with finding new markets and minimizing the costs. Electronic marketplaces applications, which is accepted as one of the modern marketing techniques has played an important role on firms and countries in achieving these two positive externalities. This study issues that electronic marketplaces which bring together buyer and seller that do not know or be aware of in chance to each other. In this context, business to business electronic marketplaces were committed in the name of foreign trade achievement and reliability criteria. Therefore, while alibabagroup.co which has the most number of participants in the world electronic marketplace application is being evaluated, there is also a brief assessment about some of prominent B2B electronic marketplaces in Turkey and the world.

That is a procedure of enticement, which prevents the useful instruments in the permitted bazaar and not solitary that it is harmful for the businesses whose representatives accept bribe, however it is also harmful for the civilisation as an entire. The occurrence of business corruption is intended as a amount of companies that presented cash, a gratitude or a service in return, in adding to every usual deal of any person who is working for a business entity from the private sector in any capacity, including the one through a mediator, happening to at minimum single juncture in the past 12 months previous to this research. The usual commonness of the business-to-corruption in the Republic of Macedonia is 3% compared to 4% at a regional level. While it is fewer than the regular pervasiveness of salaried briberies by enterprises to civic bureaucrats, this discovery designates that bribery in the secluded segment is a difficult in the Republic of Macedonia.

  4. Etude, par principes premiers, des effets de la correlation entre electrons sur les proprietes electroniques et magnetiques de polymeres pontes et de supraconducteurs a haute temperature critique

    Science.gov (United States)

    Pesant, Simon

    Description of complex systems by Density functional theory is treated in this thesis. First, the Density functional theory and a few functionals used to simulate cristals are presented. Specifically, the LDA and GGA functionnals are described and their limits are exposed. Furthermore, the Hubbard model as well as the LDA+U functionnal are addressed in this chapter. These methods enable the study of highly correlated materials. Then, results obtained on polymers are summarized in two articles. The first one treats the band gap variation of ladder-type polymers compared to non ladder type ones. The second article considers small band gap polymers. In this case, it will be shown that an hybrid functional, which contains exact exchange, is required to describe the electronic properties of the polymers under study. Finally, the last chapter address the study of cuprates superconductors. The LDA+U can account for the localization of electrons in copper orbitals. Consequently, a study of the impact of this functionnal on electronic properties of cuprates is conducted. The chapter is ended by an article treating magnetic orders in doped La 2CuO4. Supplementary materials of the second article and a description of the theory of superconductivity of Bardeen, Cooper and Schrieffer are put in annex. Keywords : Electronic correlation, DFT, LDA+U, cuprates, polymers, magnetic orders

    This study investigates luminous emissions simultaneously to electron emissions and examines their features in order to better understand the field electron emission phenomenon. A RF cavity, operating at room temperature and in pulsed mode, joined to a sophisticated experimental apparatus has been especially developed. The electron and luminous emissions are investigated on cleaned or with metallic, graphitic and dielectric particles contaminated RF surfaces in order to study their influence on these phenomena. During the surface processing, unstable luminous spots glowing during one RF pulse are detected. Their apparition is promoted in the vicinity of the metallic particles or scratches. Two hypotheses could explain their origin: the presence of micro-plasmas associated to electronic explosive emission during processing or the thermal radiation of the melted metal during this emission. Stable luminous spots glowing during several RF pulses are also detected and appear to increase on RF surfaces contaminated with dielectric particles, leading to strong and explosive luminous emissions. Two interpretations are considered: the initiation of surface breakdowns on the dielectric particles or the heating by the RF field at temperatures sufficiently intense to provoke their thermal radiation then their explosion. Finally a superconducting cavity has been adapted to observe luminous spots, which differ from the former ones bu their star shape and could be associated to micro-plasmas, revealed by the starbursts observed on superconducting cavity walls.

    With the aim of investigating the moving of the power plant Peruca dam body, measurements with the classical precise theodolite WILD T3 as well as the modern electronic instruments, KERN E2 and WILD T2000S, were carried out in order to choose the most suitable instrumentaria. All three instruments were used in measuring with the same number of horizontal angle rounds; by using the statistical tests, a significant accuracy dependency on the used instrument type was established. The most accurate results were obtained by electronic theodolite Wild T2000S (estimated variance factor {sigma}=0.61), then by KERN E2 {sigma}=1.23, and finally by T3 {sigma}=1.68. Likewise, the use of the deformation analysis, i.e. global and local tests, the highest number of significant movements was established by measuring with the WILD T2000S electronic theodolite. The interior accuracy of straight line measurement of the electronic theodolite E2 was investigated in dependence with the number of horizontal angle rounds. Unfortunately, the war in this country is the reason that the planned measurements with the GPS devices have so far not been carried out. (orig.)

    Fast electrons are one of the basic ingredients of plasma operations in many existing thermonuclear fusion research devices. However, the understanding of fast electrons dynamics during creation and sustainment of the superthermal electrons tail is far for being satisfactory. For this reason, the Electron Cyclotron Transmission (ECT) diagnostic was implemented on Tore Supra tokamak. It consists on a microwave transmission system installed on a vertical chord crossing the plasma center and working in the frequency range 77-109 GHz. Variations of the wave amplitude during the propagation across the plasma may be due to refraction and resonant absorption. For the ECT, the most common manifestation of refraction is a reduction of the received power density with respect to the signal detected in vacuum, due to the spreading and deflection of the wave beam. Wave absorption is observed in the vicinity of the electron cyclotron harmonics and may be due both to thermal plasma and to superthermal electron tails. It has a characteristic frequency dependence due to the relativistic mass variation in the wave-electron resonance condition. This thesis presents the first measurements of: the extraordinary mode optical depth at the third harmonics, the electron temperature from the width of a cyclotron absorption line and the relaxation times of the electron distribution during lower hybrid current drive from the ordinary mode spectral superthermal absorption line at the first harmonic.

  14. Generation and transport of fast electrons in the interaction of high intensity laser with matter; Generation et transport des electrons rapides dans l'interaction laser-matiere a haut flux

    Popescu, H

    2005-10-15

    The general context of this study is the Inertial Confinement for thermonuclear controlled fusion and, more precisely, the Fast Igniter (FI). In this context the knowledge of the generation and transport of fast electrons is crucial. This thesis is an experimental study of the generation and transport of fast electrons in the interaction of a high intensity laser ({>=} 10{sup 19} W/cm{sup 2}) with a solid target. The main diagnostic used here is the transition radiation. This radiation depends on the electrons which produce it and thus it gives important information on the electrons: energy, temperature, propagation geometry, etc. The spectral, temporal and spatial analysis permitted to put in evidence the acceleration of periodic electron bunches which, in this case, emit a Coherent Transition Radiation (CTR). During this thesis we have developed some theoretical models in order to explain the experimental results. We find this way two kinds of electron bunches, emitted either at the laser frequency ({omega}{sub 0}), either at the double of this frequency (2{omega}{sub 0}), involving several acceleration mechanisms: vacuum heating / resonance absorption and Lorentz force, respectively. These bunches are also observed in the PIC (particle-in-cell) simulations. The electron temperature is of about 2 MeV in our experimental conditions. The electrons are emitted starting from a point source (which is the laser focal spot) and then propagate in a ballistic way through the target. In some cases they can be re-injected in the target by the electrostatic field from the target edges. This diagnostic is only sensitive to the coherent relativistic electrons, which explains the weak total energy that they contain (about a few mJ). The CTR signal emitted by those fast electrons is largely dominating the signal emitted by the less energetic electrons, even if they contain the major part of the energy (about 1 J). (author)

    The main results obtained from this work are the following: 1 Neutron irradiation (at 300 deg. K) produces lattice defects in germanium and silicon, and a corresponding very large lowering of the thermal conductivity is observed in the low temperature region (4-300 ). The results obtained have been explained with the help of the following hypotheses: for silicon a scattering of phonons by the stress fields produced by the defects; for germanium, a supplementary scattering of the electron phonon type. 2 Annealing treatments carried out on these materials above 373 deg. K restored the thermal conductivity over the whole temperature range of the measurements (4-300 deg. K); in the case of both germanium and silicon there were two steps in the annealing process. 3 A study of the thermal conductivity of germanium (initially P or N) after an electronic irradiation showed that the scattering of phonons could depend on the state of charge of the defects thus produced. (author) [French] Les principaux resultats obtenus au cours de ce travail sont les suivants : 1 Les irradiations neutroniques (a 300 deg. K) introduisent des defauts de reseau dans le germanium et le silicium et l'on observe correlativement pour ces materiaux, une tres importante diminution de conductibilite thermique dans le domaine des basses temperatures (4-300 deg.

Les resultats obtenus ont pu etre interpretes en admettant principalement: pour le silicium, une diffusion des phonons par les champs de contrainte dus aux defauts; pour le germanium, une diffusion additionnelle du type electron-phonon. 2 Des recuits effectues sur ces materiaux au-dessus de 373 deg. K ont montre une restauration de la conductibilite thermique dans tout l'intervalle de temperature de mesure (4-300 deg.

    This paper developed a business value increasing model for electronic hospital (e-hospital) based on electronic value chain analysis. From this model, 58 hospital electronic business (e-business) solutions were developed. Additionally, this paper investigated the adoption patterns of these 58 e-business solutions within six US leading hospitals. The findings show that only 36 of 58 or 62% of the e-business solutions are fully or partially implemented within the six hospitals. Ultimately, the research results will be beneficial to managers and executives for accelerating e-business adoptions for e-hospital.

    Since the 1980's, it is known that terrestrial cosmic rays, mainly reported as atmospheric neutrons, can penetrate the natural shielding of buildings, equipments and circuit package and induce soft errors in integrated circuits and breakdown of power devices. The high-energy neutron fluxes of interest, larger than 10 MeV, range between 10 particles/cm{sup 2}/hour at sea level and 10{sup 4} particles/cm{sup 2}/hour at typical airplanes flight altitude of 30000 feet, with modulation due to solar flares. In the 1990's, the phenomenon has pervaded as a consequence of the road-map of electronic devices especially the down-scaling of transistor dimensions, the increase of signal bandwidth and the increase of the size of DRAM and SRAM memory, stand-alone or embedded on processors and system-on-chips. Failure-in-time and soft error rate became unacceptable. Test standards and design solutions have been proposed to maintain reliability of commercial products and improve those used in special high-reliability equipments such as avionic computers. The paper describes the atmospheric neutron flux, the effects in the main classes of devices and specific cases such as neutron induced single event upset observed in CMOS vs. CMOS/SOI and some mitigation issues. In this paper, a model called CCPM (critical cross-point model) is proposed to provide critical graphs of technology node sensitivity along the scaling trend of CMOS. (authors)

    1994-05-15

    This work deals with the optimization of double salience variable reluctance motors with electronic switching. It includes the control laws, the electromagnetic structure and the direct and indirect self-driving sensors. The first chapter presents the state-of-the-art of double salience reluctance machines, their characteristics, their inverters and the evolutions of their electromagnetic structure. Chapters 2 and 3 treat of the optimization of power supplies and of the electromagnetic structure, respectively. Finally, the last chapter treats of original solutions of position measurement for the self-control, one using a variable reluctance sensor, and the other using an indirect sensor. The impact of the motor characteristics on the power supply has been analyzed with the optimization of the control laws in permanent regime and low torque undulation regime. The influence of the motor structure geometry on the electromagnetic characteristics has been studied using analytic methods coupled with punctual finite-element calculations. Using a particular example, a self-oscillating power supply mode has been implemented in order to reduce the losses and the electromagnetic pollution. (J.S.)

    This work focuses on the study of the emission statistics of secondary electrons from thin carbon foils bombarded with H{sup 0}, H{sub 2}{sup +} and H{sub 3}{sup +} projectiles in the 0.25-2.2 MeV energy range. The phenomenon of secondary electron emission from solids under the impact of swift ions is mainly due to inelastic interactions with target electrons. The phenomenological and theoretical descriptions, as well as a summary of the main theoretical models are the subject of the first chapter. The experimental set-up used to measure event by event the electron emission of the two faces of a thin carbon foil traversed by an energetic projectile is described in the chapter two. In this chapter are also presented the method and algorithms used to process experimental spectra in order to obtain the statistical distribution of the emitted electrons. Chapter three presents the measurements of secondary electron emission induced by H atoms passing through thin carbon foils. The secondary electron yields are studied in correlation with the emergent projectile charge state. We show the peculiar role of the projectile electron, whether it remains or not bound to the incident proton. The fourth chapter is dedicated to the secondary electron emission induced by H{sub 2}{sup +} and H{sub 3}{sup +} polyatomic ions. The results are interpreted in terms of collective effects in the interactions of these ions with solids. The role of the proximity of the protons, molecular ion fragments, upon the amplitude of these collective effects is evidenced from the study of the statistics of forward emission. These experiences allowed us to shed light on various aspects of atom and polyatomic ion inter-actions with solid surfaces. (author)

    Science.gov (United States)

    Schneider, Ivo

    The relationship between the astronomer von Zach on the one side and the entrepreneur Joseph von Utzschneider and his partner Georg von Reichenbach on the other dates presumably from the year 1807 when Zach spent two months in Munich. Already in the same year Zach had ordered an instrument for himself and began to solicit business for the institute of Reichenbach, Utzschneider, and Liebherr, which was founded in 1804. One of the clients canvassed by Zach was the director of the observatory in Naples Zuccari. Zuccari had ordered the whole equipment for the new observatory from this institute in 1813. The instruments for Naples, which were completed in 1814, were sent accompanied by Reichenbach by land and sea to their destination where Reichenbach supervised their setup. At that time Reichenbach had separated from Utzschneider who kept the optical institute in Benediktbeuern with his new partner Joseph von Fraunhofer whereas Reichenbach became owner of the mathematical-mechanical institute in Munich. For personal and economical reasons Utzschneider began soon after to produce not only optical glass but also optical devices similar to those offered by Reichenbach. As soon as two institutes in Munich competed against each other on the market for sophisticated geodetical and astronomical instruments Zach sided with Utzschneider. Zach's main professional argument for this decision was that both competitors got the optical glass for their instruments from Utzschneider's optical institute in Benediktbeuern. This meant that Utzschneider had first choice and so the optical part of his instruments could be considered as better than that of Reichenbach`s instruments. Zach's role as an agent in Italy and France for the sale of products coming from Utzschneider's manufactories is highlighted by three of Zach's letters to Utzschneider from 1817 and 1818, two of which are reproduced here for the first time.

    ATLAS is one of the four experiments being built on the future proton-proton collider at CERN: the LHC. This experiment has a large physics program, from Standard Model to new physics. The search for the Higgs boson in two photons or in four leptons, or the search of Z' or W' needs a good energy resolution for the electromagnetic calorimeter. This thesis describes the beam tests performed on three modules of the electromagnetic end cap calorimeter. A 0.6% non-uniformity, and a 0.7% energy resolution global constant term (dominant at high energy) has been obtained. Moreover, a study on the separation between electrons and jets is also performed. This study shows that a jets rejection factor of 10{sup 5} can be obtained keeping an electron efficiency better than 78%. (author)

    In the present work, the electronic density of states of hydrogenated amorphous silicon (a-Si:H) layers in the thickness range from 300 down to {proportional_to}2 nm was examined by Near-UV-photoelectron spectroscopy (NUV-PES). The measurements yield a mean density (averaged over all directions in k space) of the extended states in the valence band close to the band edge E{sub v}, down to approximately E{sub v}-1 eV, as well as the density of states in the band-gap between E{sub v} and the Fermi level E{sub f}. An analytic model for the density of states was fitted to the measured yield data. The model describes the extended states close to the band edge as well as the localized states in the band gap. The defect parameters obtained from the fits to the 300 nm sample are elevated with respect to literature data. In contrast to PES the photocurrent measurement yield the defect parameters averaged over the entire layer thickness. Finally, the photocurrent measurements can be evaluated in the Tauc plot to yield the optical band-gap, E{sub g}{sup opt}=1.76(5) eV. The methodology developed in the first part of the thesis (PES measurement and fit of the model density of states) was then applied to various series of approximately 10 nm thin a-Si:H layers on c-Si substrates, where the deposition temperature of the layers and the concentration of their doping both by phosphorus and boron were varied. The experimental results can be summarized as follows: Ultrathin a-Si:H layers show an optimum of the deposition-temperature around 230 C. The optimum is characterized by an Urbach energy of 66(1) meV and a defect-density of 2,9(3).10{sup 18} cm{sup -3}. For undoped layers, the Fermi level lies E{sub F}-E{sub V}{sup {mu}}=1.04(6) eV, the films are therefore slightly n-type. Conductivity measurements at identically prepared thick layers on glass allow to determine the distance of the Fermi level to the conduction band mobility edge, E{sub C}{sup {mu}}-E{sub F}.

    Full Text Available Prenant les déchets électriques et électroniques comme terrain d’observation, cette recherche étudie les fondements du commerce illégal de déchets dangereux des pays développés vers les PED. En effet, malgré la multiplication des législations, le problème des déchets dans les pays développés, loin d’être traité en amont, l’est en grande partie en aval par leur délocalisation dans les PED. Les deux lectures proposées, économique et institutionnelle, permettent de montrer comment les contraintes de coût de gestion des déchets dans les pays développés conjuguées à l’imperfection et à la non-application des législations conduisent à des comportements socialement irresponsables. À partir de là, l’implication des parties prenantes est suggérée comme solution pour éliminer ce type de comportements.Based on the analysis of the waste electrical and electronic equipments (WEEE, the research investigates the motivations for the illegal cross-border trade in hazardous wastes from developed countries to developing countries. Although many developed countries have implemented waste shipment regulations, they are passing the risks and costs of E-waste to developing countries. Indeed, E-waste is often sent for recycling and refurbishing in developing countries. The two-side proposed approach (i.e. economical and institutional suggests that both the cost for firms to comply with increasing regulations and the imperfect implementation of regulatory restrictions lead to socially irresponsible behaviours. An increasing and better involvement of stakeholders may be put forward as a solution.

    In the quark model, the proton is described as a system of three quarks UUD. However, recent experiments (CERN, SLAC) have shown that the strange quarks may contribute in a significant way to the mass and the spin of the proton. The HAPPEX experiment gives one further knowledge about the question of the role the strange quarks play inside the proton. It measures parity violating asymmetry in the scattering of polarized electrons from a proton because the latter is sensitive to the contribution of the strange quarks to the electromagnetic form factors of the nucleon. The observed asymmetry is in the order of a few ppm (part per million). The main difficulty of the experiment is to identify, to estimate and to minimize, as much as possible, all the systematic effects which could give rise to false asymmetries. This thesis discusses the principle of the HAPPEX experiment, its implementation at the Jefferson Lab (JLab), the processing and the analysis of the data, the systematic errors, and finally presents the result of the first data taking (1999) and its present interpretation. The HAPPEX experiment has measured, at Q{sup 2} = 0.5 (GeV/c){sup 2}, a strange quarks contribution of (1.0 {+-} 2.3)% to the electromagnetic form factors of the nucleon. The statistics and the systematic effects (measure of the electron beam polarization and knowledge of the neutron electric form factor) contribute equally to the error. (author)

    Aujourd'hui, les façons de produire, d'organiser, d'évaluer et d'utiliser les savoirs sont en profond débat. De plus en plus, l'Etat, la société civile et l'économie tentent d'influencer les activités des universités et des laboratoires de recherche. Ces développements mettent à l'épreuve tout à la fois les fondements des systèmes d'enseignement supérieur et de recherche, l'autonomie des institutions scientifiques, la définition des frontières des savoirs et l'acceptation des sciences.

    The potential role of the information highway in the energy business was reviewed. Economic challenges, technology trends, and the opportunities available to the energy industry to exploit information technology were outlined. The `virtual` economy was identified as one of the consequences resulting from information technology, which will most likely have an impact on all aspects of the economy, including the energy industry, especially marketing. Electronic Data Interchange (EDI) for detailed business transactions, on-line services for information sharing, news, and discussion, the Internet for e-mail research, publishing, and customer contact, specialty applications for specific business functions, industry restructuring, and Fax transmission were pinpointed as the applications most likely to have the greatest impact on the business aspects of the energy industry.

  14. Use of electron beams for the production of radioactive nuclei through photo-fission; Utilisation de faisceaux d'electrons pour la production des noyaux radioactifs par photo-fission

    The IPN (institute of nuclear physics) of Orsay decided to build a linear accelerator in order to produce an electron beam of 50 MeV energy and of 10 {mu}A average intensity. It is the ALTO project (Linear Accelerator near the Tandem of Orsay). This project will be dedicated to the production of the radioactive ions using the photo-fission process. The central topic of this thesis is the study of the beam dynamics of the ALTO facility. The first part presents studies concerning the injector. The simulations made with the simulation code PARMELA allowed the optimization of the characteristics of pre-buncher (dephasing HF, accelerating field peak...) to obtain a good bunching factor at the entrance of the buncher and at the entrance of the accelerating section according to the distance separating the two systems. The second part of this thesis is related to measurements of transverse emittance of the beam at the buncher exit. The three gradients method has been selected and the optical system used is a solenoid. The results obtained are in good agreement with former measurements. Finally a calculation of the beam line was carried out to optimize the transport of the beam to the PARRNe target without degrading its characteristics. The calculation codes that have been used are BETA and TRACE-WIN. (author)

    The thesis concerns the development and implementation of numerical methods for solving the time-dependent Schroedinger equation. We first considered the case of electron-hydrogen scattering. The originality of our method is the use of a non-uniform radial grid defined by a Schwarz interpolation based on a Coulomb reference function. This grid allows many hydrogen bound states and associated matrix elements of various operators to be reproduced to machine accuracy. The wave function is propagated in time using a Split-Operator method. The efficiency of our method allows the wave function to be propagated out to large distances for all partial waves. We obtain excitation and ionization cross sections in excellent agreement with the best experimental and theoretical data. We subsequently adapted the method and the program package to study reactive atom-dihydrogen scattering. The wave packet is described using product Jacobi coordinates on a regular grid of radial coordinates combined with a basis of Legendre polynomials for the angular part (partial wave S). The wave function is analysed using a time-to-energy Fourier transform, which provides results over the energy range covered by the initial wave packet in one calculation. The method was first tested on the quasi-direct (F,H2) reaction and then applied to the indirect (C(1D),H2)reaction. The state-to-state reaction probabilities are in good agreement with those obtained by a time-independent approach. In particular, the strongly resonant structure of the (C(1D),H2) reaction probabilities is well reproduced. (author)

    The specific reaction rate constants of theFe{sup II}-Fe{sup III} electron-exchange reaction have been measured at various temperatures, acidities, and ionic strengths in water-acetone, water-methanol, and water-ethanol media. The reaction rate markedly diminishes as the water concentration in the last system decreases, approaching zero as the water concentration approaches zero. The activation energy of the exchange is the same in mixed solvent as in aqueous solution. The effective dielectric constant which the reactants ''see'' continues to be that of pure water even in water-ethanol solutions quite dilute in water. Alterations in composition of the solvation sheath of Fe{sup III} in mixed media are reflected in both electron-exchange and spectroscopic measurements. These findings in mixed solvent media support the water-bridging theory of electron exchange. (author) [French] Les constantes de vitesse specifiques de l'echange d'electrons entre Fe{sup II} et Fe{sup III} ont ete mesurees a differentes temperatures et pour differentes acidites et forces ioniques, dans des melanges d'eau et d'acetone, d'eau et de methanol et d'eau et d'ethanol. Dans le dernier systeme, la vitesse d'echange diminue considerablement a mesure que la concentration en eau decroit, et tend vers zero en meme temps que cette concentration. L'energie d'activation de l'echange est la meme dans un melange de solvants et dans une solution aqueuse. La constante dielectrique effective qui intervient entre les corps reagissants reste celle de l'eau pure, meme dans des solutions concentrees d'ethanol dans l'eau. Les changements de composition de la gaine de solvatation de Fe{sup III} dans les melanges se manifestent a la fois dans les mesures de l'echange d'electrons et dans les mesures spectroscopiques. Ces observations viennent confirmer la theorie de l'echange d'electrons fondee sur le pontage par l'eau. (author) [Spanish] El autor ha medido las constantes de velocidad especificas de la reaccion

  9. Applications of electrical resistivity measurements to research into the purification of uranium using floating molten zone by electronic bombardment; Applications des mesures de resistivite electrique a l'etude de la purification de l'uranium par fusion de zone flottante par bombardement electronique

    1964-02-01

    The purification of uranium has been achieved by zone melting. Because of the high affinity of uranium towards elements such as oxygen, contamination has been avoided by adopting the floating zone technique and by working under high vacuum. The difficulties created by the deformations of uranium rod, which are caused by anisotropy of dilatation of phases {alpha} and {beta} and allotropic transformations {alpha} {r_reversible} {beta} and {beta} {r_reversible} {alpha}, have been overcome by the use of electron bombardment stabilized by feedback. A rough control of the purification was obtained by micrographic examination, microhardness measurements, and tests of secondary recrystallization, allowed us to appreciate the new degree of purity of the uranium obtained. The investigation of the purity degree was pursued by electrical resistivity measurements at 20 deg. K. But one had to take care in the interpretation of those measurements of the anisotropy of the uranium resistivity and the influence of structure on residual resistivity. Those measurements have led us, by determination of single crystal and uranium resistivity, to be able to distinguish between the principal resistivity against axis [100] and [010]. (author) [French] La purification de l'uranium a ete realisee par l'application de la methode dite de la zone fondue. L'uranium etant particulierement reactif vis-a-vis d'elements tels que l'oxygene, les risques de contamination ont ete supprimes en adoptant la technique de la zone flottante et en operant sous vide eleve. Les difficultes creees par les deformations du barreau d'uranium, dues a l'anisotropie de dilatation des phases {alpha} et {beta} et ou passage des deux points de transformation allotropiques {alpha} {r_reversible} {beta} et {beta} {r_reversible} {alpha}, ont pu etre surmontees par l'emploi du chauffage par bombardement electronique, stabilise par un systeme tres simple de contre reaction.

    Mnif, Thameur

    Le travail presente ici est un bilan du travaux de recherche effectues sur l'injectabilite des coulis de ciment dans lu milieux fissures. Un certain nombre de coulis a base de ciment Portland et microfin ont ete selectionnes afin de caracteriser leur capacite a penetrer des milieux fissures. Une partie des essais a ete menee en laboratoire. L'etude rheologique des differents melanges a permis de tester l'influence de l'ajout de superplastifiant et/ou de fumee de silice sur la distribution granulometrique des coulis et par consequent sur leur capacite a injecter des colonnes de sable simulant un milieu fissure donne. La classe granulometrique d'un coulis, sa stabilite et sa fluidite sont apparus comme les trois facteurs principaux pour la reussite d'une injection. Un facteur de finesse a ete defini au cours de cette etude: base sur la classe granulometrique du ciment et sa stabilite, il peut entrer dans la formulation theorique du debit d'injection avant application sur chantier. La deuxieme et derniere partie de l'etude presente les resultats de deux projets de recherche sur l'injection realises sur chantier. L'injection de dalles de beton fissurees a permis le suivi de l'evolution des pressions avec la distance au point d'injection. L'injection de murs de maconnerie a caractere historique a montre l'importance de la definition de criteres de performance des coulis a utiliser pour traiter un milieu donne et pour un objectif donne. Plusieurs melanges peuvent ainsi etre predefinis et mis a disposition sur le chantier. La complementarite des ciments traditionnels et des ciments microfins devient alors un atout important. Le choix d'utilisation de ces melanges est fonction du terrain rencontre. En conclusion, cette recherche etablit une methodologie pour la selection des coulis a base de ciment et des pressions d'injection en fonction de l'ouverture des fissures ou joints de construction.

    During my internship I worked on two major projects, recommending improvements for the Center's Risk Management Workshop and helping with the strategic planning efforts for Safety and Mission Assurance (S&MA). The risk management improvements is the key project I worked on this semester through my internship, while the strategic planning is the secondary assignment. S&MA Business Office covers both aspects in its delegation, getting both spans some of the work done in the office. A risk is a future event with a negative consequence that has some probability of occurring. Safety and Mission Assurance identifies, analyzes, plans, and tracks risk. The directorate offers the Center a Risk Management Workshop, and part of the ongoing efforts of S&MA is to make continuous improvements to the RM Workshop. By using the Project Management Institute's (PMI) Standard for Risk Management, I performed a gap analysis to make improvements for our materials. I benchmarked the PMI's Risk Management Standard, compared our Risk Management Workshop materials to PMI's standard, and identified any gaps in our material. My major findings were presented to the Business Office of S&MA for a decision on whether or not to incorporate the improvements. These suggestions were made by attending JSC working group meetings, Health, Safety and Environment (HSE) panel reviews and various risk review meetings. The improvements provide better understanding of risk management processes and enhanced risk tracking knowledge and skills. Risk management is an integral part of any engineering discipline, getting exposed to this section of engineering will greatly help shape my career in the future. Johnson Space Center is a world leader in risk management processes; learning risk management here gives me a huge advantage over my peers, as well as understanding decision making in the context of risk management will help me to be a well-rounded engineer. Strategic planning is an area I had not previously

  19. Quality Measures for Digital Business Ecosystems Formation

    Science.gov (United States)

    Raza, Muhammad; Hussain, Farookh Khadeer; Chang, Elizabeth

    To execute a complex business task, business entities may need to collaborate with each other as individually they may not have the capability or willingness to perform the task on its own. Such collaboration can be seen implemented in digital business ecosystems in the form of simple coalitions using multi-agent systems or by employing Electronic Institutions. A major challenge is choosing optimal partners who will deliver the agreed commitments, and act in the coalition’s interest. Business entities are scaled according to their quality level. Determining the quality of previously unknown business entities and predicting the quality of such an entity in a dynamic environment are crucial issues in Business Ecosystems. A comprehensive quality management system grounded in the concepts of Trust and Reputation can help address these issues.

    In this survey, the structural investigations of transition metal complexes by the hyperfine interactions in the Moessbauer effect are described. The isomer shift provides a unique tool for estimating s electrons covalency in high spin complexes and one of the best pieces of evidence for the importance of bacle donation in low spin complexes. The electric field gradient deriving from quadrupole coupling measurements is correlated with the energy levels distribution of d orbitals in high spin complexes, whereas in low spin complexes it originates from the unbalanced d electrons. (authors) [French] Dans cette etude, nous decrivons les applications des interactions hyperfines dans l' effet Mossbauer a l'etude de la structure des complexes des metaux de transition. Le deplacement isomerique donne des informations tres utiles sur la covalence des electrons s dans les complexes a spin eleve et met en evidence d'une maniere nette l'importance du phenomene de 'bacle donation' dans les complexes a spin faible. Le gradient de champ electrique qui provient des mesures d'interaction quadripolaire est lie a la distribution des niveaux d'energie des orbitales d dans les complexes a spin eleve alors que dans les complexes a spin faible, il est provoque par des electrons d non apparies.

    De Leon, Samantha; Connelly-Flores, Alison; Mostashari, Farzad; Shih, Sarah C

    2010-01-01

    Electronic health records (EHRs) are expected to transform and improve the way medicine is practiced. However, providers perceive many barriers toward implementing new health information technology. Specifically, they are most concerned about the potentially negative impact on their practice finances and productivity. This study compares the productivity of 75 providers at a large urban primary care practice from January 2005 to February 2009, before and after implementing an EHR system, using longitudinal mixed model analyses. While decreases in productivity were observed at the time the EHR system was implemented, most providers quickly recovered, showing increases in productivity per month shortly after EHR implementation. Overall, providers had significant productivity increases of 1.7% per month per provider from pre- to post-EHR adoption. The majority of the productivity gains occurred after the practice instituted a pay-for-performance program, enabled by the data capture of the EHRs. Coupled with pay-for-performance, EHRs can spur rapid gains in provider productivity.

Electronic commerce is a set of procedures and technologies that automate the tasks of financial transactions using electronic means. Also, according to some authors, electronic commerce is defined as a new concept, which is being developed and which includes process of buying and selling or exchanging products, services or information via computer networks, including the Internet. Electronic commerce is not limited just to buying and selling, but it also includes all pre-sales and after-sales ongoing activities along the supply chain. Introducing electronic commerce, using the Internet and Web services in business, realizes the way to a completely new type of economy - internet economy.

    A new vacuum deposition process, named reactive evaporation, is used to realize passive thin film circuits. Using aluminium, oxidized at various steps in its vapor phase, we obtain: - Al-Al{sub 2}O{sub 3} cermet resistors (R{sub {open_square}} = 10000 {omega}{sub {open_square}}, CTR <{+-} 150 ppm/deg. C) which show oscillations of the resistivity versus the thickness of the layer, in distinction to classical theory. - Al{sub 2}O{sub 3} capacitors (C{sub {open_square}} = 60000 pf/cm{sup 2}, tg {delta} < 0.5 per cent). These thin film components present good electrical behaviour and should find interesting applications in integrated circuits. (author) [French] Une nouvelle technique de depot sous vide, l'evaporation reactive est utilisee pour realiser des circuits passifs en couches minces. En oxydant, en phase vapeur, de l'aluminium a differents degres, on obtient: - des resistances en cermet Al-Al{sub 2}O{sub 3} (R{sub {open_square}} = 10000 {omega}{sub {open_square}}, CTR <{+-} 150 ppm) dont Ia resistivite oscille en fonction de l'epaisseur, contrairement aux previsions de la theorie classique. - Des capacites en Al{sub 2}O{sub 3} (C{sub {open_square}} = 60000 pf/cm{sup 2}, tg {delta} < 0.5 pour cent). Ces elements presentent de bonnes caracteristiques electriques et seraient avantageusement utilises en circuits integres. (auteur)

  15. Social Business

    Directory of Open Access Journals (Sweden)

    Maria Cristina ENACHE

    2015-09-01

    Full Text Available The field of social business is growing rapidly and attracting increased attention from many sectors. The term itself shows up frequently in the media, is referenced by public officials, have become common on universities. The reasons behind the popularity of social entrepreneurship are many. On the most basic level, there’s something inherently interesting and appealing about entrepreneurs and the stories of why and how they do what they do. The interest in social entrepreneurship transcends the phenomenon of popularity and fascination with people. Social entrepreneurship signals the imperative to drive social change, and it is that potential payoff, with its lasting, transformational benefit to society, that sets the field and its practitioners apart. Although the potential benefits offered by social entrepreneurship are clear to many of those promoting and funding these activities, the actual definition of what social entrepreneurs do to produce this order of magnitude return is less clear. In fact, we would argue that the definition of social entrepreneurship today is anything but clear. As a result, social entrepreneurship has become so inclusive that it now has an immense tent into which all manner of socially beneficial activities fit. In some respects this inclusiveness could be a good thing. If we can achieve a rigorous definition, then those who support social entrepreneurship can focus their resources on building and strengthening a concrete and identifiable field. Absent that discipline, proponents of social entrepreneurship run the risk of giving the skeptics an ever-expanding target to shoot at, and the cynics even more reason to discount social innovation and those who drive it.

In today's global world, business ethics has become an indispensable part of the hotel business practices and prerequisite for achieving business success. Business ethics receives strategic significance because it creates a system of governance based on ethical principles that enables the hotel to properly respond to the demands of all interest groups. Successful will be precisely those hotels that do not separate ethics from profitability, but those that successfully coordinate them in its business. Business ethics has a strong impact on hotel business, and a major role in its implementation has a hotel management. Every responsible hotel management should, in accordance with the business philosophy of hotel, devise various ethical practices and ethical codes of conduct prescribed by the employees who will be an important standard of a business object.

    1999-01-01

    Full Text Available Die häufigste mykotische Infektion des Penis stellt die Balanitis/Balonoposthitis durch Candida albicans dar. Sie weist eine steigende Inzidenz auf und scheint vornehmlich durch Genitalverkehr übertragen zu werden. Penile Infektionen durch Dermatophyten sind sehr selten, obwohl die Tinea inguinalis zu den häufigeren Erkrankungen zählt. Eine Mitbeteiligung des Penis im Rahmen von Systemmykosen kennzeichnet zumeist ein schwer verlaufende Erkrankung. Ursächlich kann beim immunoinkompetenten Patienten nahezu jeder Erreger in Frage kommen. Biopsie sowie Gewebekultur aus den meist ulzerativen Veränderungen können die Diagnose sichern. Die meisten superfiziellen Infektionen sprechen zufriedenstellend auf eine topische antimykotische Behandlung an, insbesondere wenn Provokationsfaktoren und die Möglichkeit der sexuellen Transmission berücksichtigt werden. Ausgedehnte Infektionen durch Dermatophyten, Hefen und natürlich systemische Infektionen erfordern eine systemische antimykotische Therapie.

    The purpose of this report is to examine briefly the diffusion of neutrons by substances, particularly by crystals containing permanent atomic or ionic magnetic moments. In other words we shall deal with ferromagnetic, antiferromagnetic, ferrimagnetic or paramagnetic crystals, but first it is necessary to touch on nuclear diffusion of neutrons. We shall start with the interaction of the neutron with a single diffusion centre; the results will then be applied to the magnetic interactions of the neutron with the satellite electrons of the atom; finally we shall discuss the diffusion of neutrons by crystals. (author) [French] Le but de ce rapport est d'examiner, brievement, la diffusion des neutrons par les substances, et surtout, par des cristaux qui contiennent des moments magnetiques atomiques ou ioniques permanents. C'est-a-dire que nous nous interesserons aux cristaux ferromagnetiques, antiferromagnetiques, ferrimagnetiques ou paramagnetiques; il nous faut cependant rappeler d'abord la diffusion nucleaire des neutrons. Nous commencerons par l'interaction du neutron avec un seul centre diffuseur; puis les resultats seront appliques aux interactions magnetiques du neutron avec les electrons satellites de l'atome; enfin nous discuterons la diffusion des neutrons par les cristaux.

    Die Organtransplantation stellt eine verbreitete Therapie dar, um bei krankheitsoder unfallbedingter Schädigung eines Organs die Gesamtheit seiner Funktionen wieder herzustellen, indem es durch ein Spenderorgan ersetzt wird. Organtransplantationen werden für die Leber, die Niere, die Lunge, das Herz oder bei schweren grossflächigen Verbrennungen der Haut vorgenommen. Der grosse apparative, personelle und logistische Aufwand und die Risiken der Transplantationschirurgie (Abstossungsreaktionen) sowie die mangelnde Verfügbarkeit von immunologisch kompatiblen Spenderorganen führen jedoch dazu, dass der Bedarf an Organtransplantaten nur zu einem sehr geringen Teil gedeckt werden kann. Sind Spenderorgane nicht verfügbar, können in einzelnen Fällen lebenswichtige Teilfunktionen, wie beispielsweise die Filtrationsfunktion der Niere durch die Blutreinigung mittels Dialyse ersetzt oder, bei mangelnder Funktion der Bauchspeicheldrüse (Diabetes), durch die Verabreichung von Insulin ein normaler Zustand des Gesamtorganismus auch über Jahre hinweg erhalten werden. Bei der notwendigen lebenslangen Anwendung apparativer oder medikamentöser Therapie können für den Patienten jedoch häufig schwerwiegende, möglicherweise lebensverkürzende Nebenwirkungen entstehen. Daher werden in der Forschung Alternativen gesucht, um die Funktionen des ausgefallenen Organs durch die Implantation von Zellen oder in vitro gezüchteten Geweben möglichst umfassend wieder herzustellen. Dies erfordert biologisch aktive Implantate, welche die für den Stoffwechsel des Organs wichtigen Zellen enthalten und einen organtypischen Stoffwechsel entfalten.

    Barriers foreseen for the separation of uranium isotopes by gaseous diffusion must posses pores of about 100 Angstrom radius and as high an output as possible. They should thus be of small but uniform thickness. In view of these conditions it is necessary to adapt the normal methods available for studying porous materials in order to check the characteristics of the prototypes examined. It has been found that only by cross-comparison of data from various methods can progress in the development of different prototypes be followed. The following account consists of two parts: 1) A review of the main experimental methods we have used: a) various absorption methods, b) electron microscopy, c) X-ray studies, d) mercury porosimetry, e) liquid permeability, f) gas permeability, g) measurement of separation efficiency. 2) Comparison of the results obtained using these various methods and their application with a view to acquiring as complete a knowledge as possible of the structure of the barrier.

    Full Text Available The Internet technology has brought major changes to the way business is conducted today. Many terms have been coined to represent the electronic concepts and applications such as e-Business and e-Commerce terms. These terms are commonly used to represent the new transformation of business processes and transactions. In Malaysia, e-Business adoption has not only captured the interest of large organizations but it has also been acknowledged and adopted by small, medium and micro sized enterprises. Implementing e-Business requires significant changes in the company’s structure, culture, strategy, procedures and responsibilities. However, the challenges never stop people from venturing into this new business concept. The aim of this study is to look into e-Business potential for micro sized businesses that operates from home. In this study both qualitative and quantitative method are used. This paper present a review of the literature pertaining to e-Business, home-based business, the qualitative study and the early findings from the study.

    Activity Based Costing (ABC) is a methodology used to measure the cost of performing business processes and to trace these costs to specific products and services. As a cost-reporting and management tool, ABC provides information on the resources (e.g., people, materials, equipment, facility space, etc.) used to accomplish an organization's mission. This is not just cost information; ABC also identifies an organization's processes, process boundaries, the people and organizational units involved in a process, the cost to execute single or multiple cycles of a process, process outputs (final products and services and work-in-process), and process customers. Whereas traditional cost systems simply capture the cost of producing products and services, ABC calculates costs based on the relevant activities performed in producing products and services. The fundamental difference between these two methodologies is that, where the traditional method allocates cost through overhead rates and surcharges, ABC assigns costs based on causal relationships. In short-you only pay for what you get, which may be new for some Parties. The report concluded and supported that ABC cost systems provide a more representative perspective of financial reality than traditional cost accounting systems because ABC systems trace, rather than allocate, resource costs to the activities they support. Allocation is the traditional practice of assigning some costs, such as overhead or indirect administrative and support expenses, by a certain formula, such as a multiple of direct labour costs. Allocation can be misleading because some processes consume more overheads than others do. In the private sector, this allocation problem causes managers to think that a certain product is profitable, when in fact it loses money. In the public sector, it may cause a wrong make/buy decision or an inappropriate estimate of productivity-and mask the fact that administrative and support expenses are

    Antoine, C.Z.; Martin, J.

    1997-01-01

    This article draws the saga of particle acceleration in CEA facilities at Orme Des Merisiers. At the end of the sixties an electron linear accelerator with copper accelerating cavities was built. This machine presented a great step forwards: its luminosity was one thousand stronger and it could tell details as small as a third of a proton's size. As early as 1970 it was evident to use superconducting cavities otherwise the quest for more energetic particles would have led to design monsters devourer of energy. In 1990 MACSE an accelerator equipped with superconducting cavities produced the first continuous electron beam. MACSE was an efficient laboratory bench to study and develop superconducting cavities. Huge energy savings,a reduced beam emittance and a far better accelerating gradient are the main advantages of superconductivity. These advantages will fully benefit accelerators only if improvements are made concerning the mastery of thermal transfers, cryogenic power, ultra-vacuum techniques and the coupling of cavities.

    The substitution of hot filaments by field-effect microtips has several advantages in many electronic applications. LETI has already proved the interest of this principle for flat panel displays; many people believe it could also provide novel microwave sources. Moreover, the properties of the emission enable to seek new electron optics applications that were not possible with hot filaments. An interferometry experiment was designed, developed and characterized in order to evaluate the potential of the microtips fabricated in the LETI for such applications. This experiment is composed of a Mollenstedt biprism, of electrostatic lenses and an imaging system composed of deflection plates, a small aperture diaphragm (1 {mu}m) and a channel electron multiplier. Quantum wave effects have been observed, which confirms the good coherence properties of the source. Moreover, this experimental setup enables to better understand the physical phenomenon of the emission of the tips fabricated in the LETI, and to propose some technological improvements for the applications we seek. It is also designed for electron holography applications, and should allow the study of new compact electron optics apparatus taking account of the wave properties of the electrons emitted by microtips.

  3. Vecteurs Singuliers des Theories des Champs Conformes Minimales

    Science.gov (United States)

    Benoit, Louis

    En 1984 Belavin, Polyakov et Zamolodchikov revolutionnent la theorie des champs en explicitant une nouvelle gamme de theories, les theories quantiques des champs bidimensionnelles invariantes sous les transformations conformes. L'algebre des transformations conformes de l'espace-temps presente une caracteristique remarquable: en deux dimensions elle possede un nombre infini de generateurs. Cette propriete impose de telles conditions aux fonctions de correlations qu'il est possible de les evaluer sans aucune approximation. Les champs des theories conformes appartiennent a des representations de plus haut poids de l'algebre de Virasoro, une extension centrale de l'algebre conforme du plan. Ces representations sont etiquetees par h, le poids conforme de leur vecteur de plus haut poids, et par la charge centrale c, le facteur de l'extension centrale, commune a toutes les representations d'une meme theorie. Les theories conformes minimales sont constituees d'un nombre fini de representations. Parmi celles-ci se trouvent des theories unitaires dont les representation forment la serie discrete de l'algebre de Virasoro; leur poids h a la forme h_{p,q}(m)=[ (p(m+1) -qm)^2-1] (4m(m+1)), ou p,q et m sont des entiers positifs et p+q= 2. Ces representations possedent un sous-espace invariant engendre par deux sous-representations avec h_1=h_{p,q} + pq et h_2=h_{p,q} + (m-p)(m+1-q) dont chacun des vecteurs de plus haut poids portent le nom de vecteur singulier et sont notes respectivement |Psi _{p,q}> et |Psi_{m-p,m+1-q}>. . Les theories super-conformes sont une version super-symetrique des theories conformes. Leurs champs appartiennent a des representation de plus haut poids de l'algebre de Neveu-Schwarz, une des deux extensions super -symetriques de l'algebre de Virasoro. Les theories super -conformes minimales possedent la meme structure que les theories conformes minimales. Les representations sont elements de la serie h_{p,q}= [ (p(m+2)-qm)^2-4] /(8m(m+2)) ou p,q et m sont

    2015-09-01

    Full Text Available A Social Business embraces networks of people to create business value. A Social Business connects people to expertise. It enable individuals – whether customers, partners or employees – to form networks to generate new sources of innovation, foster creativity, and establish greater reach and exposure to new business opportunities. It establishes a foundational level of trust across these business networks and, thus, a willingness to openly share information. It empowers these networks with the collaborative, gaming and analytical tools needed for members to engage each other and creatively solve business challenges. A Social business strives to remove unnecessary boundaries between experts inside the company and experts in the marketplace. It embraces the tools and leadership models that support capturing knowledge and insight from many sources, allowing it to quickly sense changes in customer mood, employee sentiment or process efficiencies. It utilizes analytics and social connections inside and outside the company to solve business problems and capture new business opportunities. A Social Business leverages these social networks to speed up business, gaining real time insight to make quicker and better decisions. It gets information to customers and partners in new ways -- faster. Supported by ubiquitous access on mobile devices and new ways of connecting and working together in the Cloud and on open platforms, a Social Business turns time and location from constraints into advantages. Business is free to occur when and where it delivers the greatest value, allowing the organization to adapt quickly to the changing marketplace. We believe the most effective approach to enabling a Social Business centers around helping people discover expertise, develop social networks and capitalize on relationships.

    1998-01-01

    For managers in large, well-established businesses, the Internet is a tough nut to crack. It is very simple to set up a Web presence and very difficult to create a Web-based business model. Established businesses that over decades have carefully built brands and physical distribution relationships risk damaging all they have created when they pursue commerce through the Net. Still, managers can't avoid the impact of electronic commerce on their businesses. They need to understand the opportunities available to them and recognize how their companies may be vulnerable if rivals seize those opportunities first. Broadly speaking, the Internet presents four distinct types of opportunities. First, it links companies directly to customers, suppliers, and other interested parties. Second, it lets companies bypass other players in an industry's value chain. Third, it is a tool for developing and delivering new products and services to new customers. Fourth, it will enable certain companies to dominate the electronic channel of an entire industry or segment, control access to customers, and set business rules. As he elaborates on these four points, the author gives established companies a systematic way to sort through the risks and rewards of doing business in cyberspace.

    The temperatures needed to produce thermonuclear reactions are of the order of several million degrees Kelvin. Devising methods for measuring such temperatures has been the subject of research in many countries. In order to present the problem clearly and to demonstrate its importance, the author reviews the various conditions which must be fulfilled in order that reactions may be qualified as thermonuclear. The relationship between the temperature and the cross-section of the reactions is studied, and it is shown that the notion of temperature in the plasmas is complex, which leads to a consideration of the temperature of the ions and that of the electrons. None of the methods for the temperature measurements is completely satisfactory because of the hypotheses which must be made, and which are seldom fulfilled during high-intensity discharges in the plasmas. In practice it is necessary to use several methods simultaneously. (author) [French] Les temperatures necessaires pour produire des reactions thermonucleaires sont de l'ordre de plusieurs millions de degres Kelvin.

Aucune des methodes de mesure des temperatures n'est completement satisfaisante en raison des hypotheses qu'elles exigent et qui sont rarement realisees lors des decharges a haute intensite dans les plasmas.

    We studied excitation and relaxation of electrons involved during interaction of visible and VUV femtosecond pulses with dielectrics. The generated population of hot electrons, having energy of few eV to few tens of eV above the bottom of the conduction band, is responsible of phenomena ranging to defect creation to optical breakdown. Owing to two techniques: photoemission and transient photoconductivity we improve the understanding of the The first photoemission experiments deal with dielectrics irradiated by 30 fs IR pulses. The photoemission spectra measured show a large population of electrons which energy rise up to 40 eV. We interpret this result in terms of a new absorption process: direct multi-photons inter-branch transitions. The 2. type of photoemission experiments are time resolved 'pump/probe' investigation. We study the relaxation of electrons excited by a VUV pulses. We used the high order harmonics (HOH) as light sources. We found surprisingly long decay time in the range of ps timescale. Last type of experiments is photoconductivity studies of diamond samples. Using HOH as light source we measure the displacement current induced by excited electrons in the conduction band. Those electrons relax mainly by impact ionisation creating secondary electrons. Hence by probing the number of electrons we were able to measure the efficiency of these relaxation processes. We observe a diminution of this efficiency when the energy of exciting photons is above 20 eV. Owing to Monte-Carlo simulation we interpret this result in terms of band structure effect. (author)

    This work focuses on the study of the emission statistics of secondary electrons from thin carbon foils bombarded with H{sup 0}, H{sub 2}{sup +} and H{sub 3}{sup +} projectiles in the 0.25 - 2.2 MeV energy range. The phenomenon of secondary electron emission from solids under the impact of swift ions is mainly due to inelastic interactions with target electrons. Phenomenological and theoretical descriptions as well as a summary of the main theoretical models are the subjects of the first chapter. The experimental set-up used to measure event by event the electron emission of the two faces of the thin carbon foils crossed by an energetic projectile is described in the chapter two. In this chapter there are also presented the method and the algorithms used to process experimental spectra in order to obtain the statistical distribution of the emitted electrons. Chapter three presents the measurements of secondary electron emission induced by H{sup 0} atoms passing through thin carbon foils. The secondary electron yields are studied in correlation with emergent projectile charge state. We show the peculiar role of the projectile electron, whether it remains or not bound to the incident proton. The fourth chapter is dedicated to the secondary electron emission induced by H{sub 2}{sup +} and H{sub 3}{sup +} polyatomic ions. The results are interpreted in terms of collective effects in the interactions of the ions with solids. The role of the proximity of the protons, molecular ions fragments, upon the amplitude of these collected effects is evidenced from the study of the statistics of forward emission. The experiments allowed us to shed light on various aspects of atom and polyatomic ion interactions with solid surfaces. (author) 136 refs., 41 figs., 3 tabs.

    Risk in international business can stress risk adverse behaviour to counteract foreign market uncertainty or individual entrepreneurial risk taking behaviour dependent on the characteristics of both the business sector and the individual. International business theory would suggest that the perception of risk may differ in situations including where new market entry is incremental, is taken in larger or earlier stages, or indeed whether it may be experienced in a continually fluctuating manne...

    Prime stylized facts of international business cycle theory refer to positive correlation in the cyclical components of important macroeconomic variables across countries. However a number of indicators of business cycle synchronization do not point to clear trends. It can be ascribed to the fact that different forces influence level of business cycle correlation. When investigating into the forces behind the commonness in aggregate fluctuations economic research seems to have pointed in two ...

  12. Why business models matter.

    Science.gov (United States)

    Magretta, Joan

    2002-05-01

    "Business model" was one of the great buzz-words of the Internet boom. A company didn't need a strategy, a special competence, or even any customers--all it needed was a Web-based business model that promised wild profits in some distant, ill-defined future. Many people--investors, entrepreneurs, and executives alike--fell for the fantasy and got burned. And as the inevitable counterreaction played out, the concept of the business model fell out of fashion nearly as quickly as the .com appendage itself. That's a shame. As Joan Magretta explains, a good business model remains essential to every successful organization, whether it's a new venture or an established player. To help managers apply the concept successfully, she defines what a business model is and how it complements a smart competitive strategy. Business models are, at heart, stories that explain how enterprises work. Like a good story, a robust business model contains precisely delineated characters, plausible motivations, and a plot that turns on an insight about value. It answers certain questions: Who is the customer? How do we make money? What underlying economic logic explains how we can deliver value to customers at an appropriate cost? Every viable organization is built on a sound business model, but a business model isn't a strategy, even though many people use the terms interchangeably. Business models describe, as a system, how the pieces of a business fit together. But they don't factor in one critical dimension of performance: competition. That's the job of strategy. Illustrated with examples from companies like American Express, EuroDisney, WalMart, and Dell Computer, this article clarifies the concepts of business models and strategy, which are fundamental to every company's performance.

  13. Information Security Audit in e-business applications

    2007-01-01

    Full Text Available Electronic business (e-business are different than other business because it involves any commercial or business activity that takes place by means of electronic facilities (buy and selling online, including on the Internet, proprietary networks and home banking, instead of through direct physical exchange or contact. This system creates an environment that operates at a much greater speed than traditional methods and involves much less paper–based evidence of activities. These e-business related risks should not be considered in isolation but rather as part of the overall internal control framework of an entity. It is essential to identify and assess the risks associated with an e-business environment and management should develop an e-business strategy that identifies and addresses risks. The e-business Information Systems (IS audit is a critical component of the e-business plan.

  16. Transport de paires EPR dans des structures mesoscopiques

    Science.gov (United States)

    Dupont, Emilie

    Dans cette these, nous nous sommes particulierement interesses a la propagation de paires EPR1 delocalisees et localisees, et a l'influence d'un supraconducteur sur le transport de ces paires. Apres une introduction de cette etude, ainsi que du cadre scientifique qu'est l'informatique quantique dans lequel elle s'inscrit, nous allons dans le chapitre 1 faire un rappel sur le systeme constitue de deux points quantiques normaux entoures de deux fils supraconducteurs. Cela nous permettra d'introduire une methode de calcul qui sera reutilisee par la suite, et de trouver egalement le courant Josephson produit par ce systeme transforme en SQUID-dc par l'ajout d'une jonction auxiliaire. Le SQUID permet de mesurer l'etat de spin (singulet ou triplet), et peut etre forme a partir d'autres systemes que nous etudierons ensuite. Dans le chapitre 2, nous rappellerons l'etude detaillee d'un intricateur d'Andreev faite par un groupe de Bale. La matrice T, permettant d'obtenir le courant dans les cas ou les electrons sont separes spatialement ou non, sera etudiee en detail afin d'en faire usage au chapitre suivant. Le chapitre 3 est consacre a l'etude de l'influence du bruit sur le fonctionnement de l'intricateur d'Andreev. Ce bruit modifie la forme du courant jusqu'a aboutir a d'autres conditions de fonctionnement de l'intricateur. En effet, le bruit present sur les points quantiques peut perturber le transport des paires EPR par l'intermediaire des degres de liberte. Nous montrerons que, du fait de l'"intrication" entre la charge de la paire et le bruit, la paire est detruite pour des temps longs. Cependant, le resultat le plus important sera que le bruit perturbe plus le transport des paires delocalisees, qui implique une resonance de Breit-Wigner a deux particules. Le transport parasite n'implique pour sa part qu'une resonance de Breit-Wigner a une particule. Dans le chapitre 4, nous reviendrons au systeme constitue de deux points quantiques entoures de deux fils

    The business of exploration is persistently misunderstand. Why? Misunderstandings persist and even pervade educated, sophisticated, and obviously capable business practitioners and savants of an array of disciplines - finance, economics, and the management sciences. Routine and appropriate assumptions that apply for most businesses invoke nonsense applied to exploration, a unique business. The uniqueness of exploration, unrecognized, sustains the misunderstandings. The authors will not here obliterate these obdurate misunderstandings with some revelation. They show, however, how the misunderstandings naturally arise among those who certainly are not used to being naive

    Full Text Available Unprecedant development of the IT influenced the development of the electronic business and internet. Introducing the electronic business into companies worldwide and accepting the new global media - internet, have enabled the development of the new area of the marketing practice - electronic marketing. Electronic marketing has kept the basics of the traditional marketing, but it has also adapted to the new standards in the business and, together with internet, it has opened up remarkable opportunities for the small and big companies, through the global accessibility of their offers. Electronic business is become the imperative of the modern business under the conditions of today's economic and political globalization, which dictates the rules of conduct among the world market players. The usage of internet has enabled direct, interactive communication, but has also started questions regarding security of that communication and protection of company's or individual's data. It is certain that the area of the electronic business and electronic trade, has unstoppable and unpredictable directions of development and so many potential users, while globalization has unique goal, but many interested masters. How the world will look like in the future, what countries will fit in, and what countries will dictate the tempo of the further development, remains to be seen.

    The first three chapters of these lecture notes are devoted to generalities concerning current algebra. The weak currents are defined, and their main properties given (V-A hypothesis, conserved vector current, selection rules, partially conserved axial current,...). The SU (3) x SU (3) algebra of Gell-Mann is introduced, and the general properties of the non-leptonic weak Hamiltonian are discussed. Chapters 4 to 9 are devoted to some important applications of the algebra. First one proves the Adler- Weisberger formula, in two different ways, by either the infinite momentum frame, or the near-by singularities method. In the others chapters, the latter method is the only one used. The following topics are successively dealt with: semi leptonic decays of K mesons and hyperons, Kroll- Ruderman theorem, non leptonic decays of K mesons and hyperons ( {delta}I = 1/2 rule), low energy theorems concerning processes with emission (or absorption) of a pion or a photon, super-convergence sum rules, and finally, neutrino reactions.

The first part is a review of proportional chamber operation principles and presents the different possibilities for the architecture of the electronics. The second part involves electronic signal processing for best signal-to-noise ratio. We present a time-variant filter based on a second order base line restorer.It allows a simple pole-zero and tail cancellation at high counting rates. Also, various interpolating algorithms for cathode strip chambers have been studied. The last part reports the development of a complete electronic system, from the preamplifiers up to the readout and control interface, for the cathode strip chambers in the focal plane of the BBS Spectrometer at KVI, Holland. The system is based on application specific D-size VXI modules. In all modules, the 16-bit ADCs and FIFO memory are followed by a Digital Signal Processor, which performs data filtering and cathode induced charge interpolation.

    After having chosen between different cooling solutions for a given power electronics component, the dimensioning of a two-phase forced convection loop is described. The power electronics component is a 12 x 12 mm silicon pellet which can dissipate up to 400 W/cm{sup 2} heat fluxes. In a first step, the minimum size of channels is determined according to fluid characteristics, pressure drop and critical fluxes. In a second step, the coupled dimensioning of both the evaporator and the condenser is determined for different values of pipes diameter and mass flow rates. (J.S.) 8 refs.

    After having chosen between different cooling solutions for a given power electronics component, the dimensioning of a two-phase forced convection loop is described. The power electronics component is a 12 x 12 mm silicon pellet which can dissipate up to 400 W/cm{sup 2} heat fluxes. In a first step, the minimum size of channels is determined according to fluid characteristics, pressure drop and critical fluxes. In a second step, the coupled dimensioning of both the evaporator and the condenser is determined for different values of pipes diameter and mass flow rates. (J.S.) 8 refs.

    This new welding process has been developed by the Commissariat a l'Energie Atomique (CEA) in France. The edges of the work-pieces are melted by the impact of an electron beam produced by an electron gun. Welding is carried out in a vacuum of 10{sup -4} to 10{sup -8} mm of mercury. The welding machine consists, diagrammatically, of: a) a metal enclosure in which a vacuum is produced; b) a cathode for electron emission, a high-voltage generator for accelerating these electrons, a focusing device; c) a mechanical device for moving (rotating) the work-piece. Advantages of the process: 1) possible welding of highly oxidizable metals (e.g. zirconium); 2) fabrication of high-vacuum-sealed metal containers; 3) production of very deeply penetrated welds. Therefore, this new process is particularly advantageous for atomic power applications, the fabrication of electron tubes and, more generally, for all industries in which very special metals are used. (author) [French] Ce procede de soudage a ete recemment mis au point au Commissariat a l'Energie Atomique en France (CEA). Il consiste a utiliser, pour fondre les levres des pieces a souder, l'impact d'un faisceau d'electrons produit par un canon a electrons. Le soudage s'effectue sous un vide de 10{sup -4} a 10{sup -8} mm de mercure. La machine a souder se compose schematiquement: a) d'une enceinte metallique ou l'on fait le vide; b) d'une cathode emettant des electrons, d'un generateur H.T. permettant d'accelerer ces electrons d'un dispositif de focalisation; c) d'un dispositif mecanique permettant le deplacement (rotation) de la piece a souder. Avantages de ce procede: 1) possibilite de souder les metaux tres oxydables (exemple: zirconium); 2) realisation de 'containers' metalliques fermes sous vide pousse; 3) obtention de profondeurs de soudures considerables. Ce nouveau procede est donc particulierement interessant pour l ' energie atomique, la fabrication des tubes electroniques et, en general, toutes les industries

    As a business system, an enterprise represents a complex, dynamic, stochastic, open and organisational system. Certain specific features of a hotel enterprise as a business system of project business result from the activity it performs and from project-based business and development management. As an enterprise based on project business, its distinguishing features include the interconnectedness of business subsystems and the overlapping a hotel enterprise’s business function.

  4. Improvements in fast-neutron spectroscopy methods (1961); Amelioration des methodes de spectrometrie des neutrons rapides (1961)

    This research aimed at improving fast-neutron electronic detectors based on n-p elastic scattering. The first part concerns proportional counters; careful constructional methods have made it possible to plot mono-energetic neutron spectra in the range 700 keV - 3 MeV with a resolution of 7 per cent. The second part concerns scintillation counters: an organic scintillator and an inorganic scintillator covered with a thin layer of a scattering agent. An exact study of the types of scintillation has made it possible to develop efficient discriminator circuits. Different neutron spectra plotted in the presence of a strong gamma background are presented. The last part deals with the development of form discrimination methods for the study, in the actual beam, of the elastic scattering of 14.58 MeV electrons. With hydrogen, the distribution f ({phi}) of the recoil protons is f({phi}) = 1 + 0.034 cos {phi} + 0.042 cos{sup 2} {phi}. With tritium the scattering is strongly anisotropic; the curve representing the variation of the differential cross-section for the elastic scattering in the centre of mass system is obtained with a target containing 1 cm{sup 3} of tritium. (author) [French] Le travail a porte sur l'amelioration des detecteurs electroniques de neutrons rapides bases sur la diffusion elastique n-p. La premiere partie est relative aux compteurs proportionnels; des methodes soignees de fabrication ont permis des traces de spectres de neutrons monoenergetiques dans le domaine 700 keV - 3 MeV avec une resolution de 7 pour cent.

    The enhanced electronic field emission from large area metallic surfaces lowers performances of industrial devices that have to sustain high electric field under vacuum. Despite of numerous investigations in the past, the mechanisms of such an emission have never been well clarified. Recently, research in our laboratory has pointed out the importance played by conducting sites (particles and protrusions). A refined geometrical model, called superposed protrusions model has been proposed to explain the enhanced emission by local field enhancement. As a logical continuation, the present work aims at testing this model and, in the same time, investigating the means to suppress the emission where it is undesirable. Thus, we have showed: the cause of current fluctuations in a continuous field regime (DC), the identity of emission characteristics ({beta}, A{sub e}) in both radiofrequency (RF) and DC regimes, the effectiveness of a thermal treatment by extern high density electronic bombardment, the effectiveness of a mechanical treatment by high pressure rinsing with ultra pure water, the mechanisms and limits of an in situ RF processing. Furthermore, the electronic emission from insulating particles has also been studied concurrently with a spectral analysis of the associated luminous emission. Finally, the refined geometrical model for conducting sites is reinforced while another model is proposed for some insulating sites. Several emission suppressing treatments has been explored and validated. At last, the characteristic of a RF pulsed field emitted electron beam has been checked for the first time as a possible application of such a field emission. (author)
