    There are still many problems in the field of measurement and control of neutron flux. The present studies in connexion with high flux reactors contribute to the solution of these problems which concern specialists in reactor control. The present state of this investigation and the results of different studies carried out in France by the C A and the EDF are pointed out: A - In the nuclear instrumentation field, work is at present devoted to the technologies used to develop detectors and cables, which have to work at high temperature and in a high {gamma} background; fast electronic techniques are applied to fission counters to measure low neutron fluxes in a high {gamma} background (10 Rh). B - In the control and safety field, there is a real need for studies on the behaviour of reactors in the subcritical state. This increases the margin of security during restarts when poison effects must be overcome The perturbations due to control rod movements necessitate a new organisation of power level safety and control assemblies, in connexion with thermal or activation measurements. Two methods of fast start-up are described. They are related to the fission rate measurement as a function of time. This is done either continuously by a constant and high reactivity change, or step by step. The application of automatic techniques to detector motion seems to give the answer to control and safety in normal start-up. C - The scope of these studies covers the methods used for the control of E.D.F. 3, which are described. (authors) [French] La mesure et le controle du flux neutronique dans les piles de puissance posent encore de nombreux problemes. Les etudes actuellement entreprises dans le domaine des piles a haut flux, doivent apporter une contribution importante a la solution de ces problemes qui interessent les specialistes du controle des piles de puissance. On analyse l'etat actuel de ces etudes et on donne les resultats des differents travaux effectues en France, dans les differents laboratoires du Commissariat a l'Energie Atomique et de l'Electricite de France. A - Dans le domaine de l'instrumentation, ces etudes portent actuellement sur les technologies utilisees pour le developpement des detecteurs et cables susceptibles de fonctionner a haute temperature; sous rayonnement {gamma} eleve - et sur les techniques d'electronique rapide appliquees aux chambres a fissions qui permettent de faire des mesures de flux neutronique sous rayonnement {gamma} eleve (105 R/h). B - Dans le domaine general du controle et de la securite, les difficultes de redemarrage liees aux empoisonnements par les produits de fission conduisent a des etudes approfondies sur le comportement du reacteur en regime sous-critique. Les perturbations apportees aux mesures neutroniques par le mouvement des barres de controle necessitent une nouvelle organisation des chaines de mesure et de securite neutronique faisant intervenir au niveau de puissance des parametres correcteurs tels que: puissance thermique, temperature, activation Azote 16. En ce qui concerne les demarrages rapides, deux methodes nouvelles sont decrites liees essentiellement a la mesure du taux de fissions en fonction du temps, soit dans le cas d'une liberation continue a vitesse constante et elevee de reactivite, soit dans le cas d'une liberation de reactivite par paliers. Par ailleurs, l'application des techniques de deplacement automatique des detecteurs dans le cas des demarrages normaux semblent apporter une solution rationnelle au controle et a la securite. C - Dans le cadre des techniques ci-dessus, on decrit les dispositifs retenus pour la mesure et le controle de la puissance de la pile EDF III. (auteurs)

    I - A measurement method based on {alpha} {gamma} coincidences is used for activity measurements on {sup 241}Am in the presence of a strong {alpha} activity due to Pu. The sensitivity of the apparatus makes it possible to detect: less than 10{sup -7} {mu}C {sup 241}Am in the presence of a Pu activities several hundred times greater. II - The same equipment has been used for {alpha} measurements on {alpha}-emitting sources in the presence of very strong {beta} and {gamma} activities. In particular results are given for {alpha}-activity measurements on powder samples. It is even possible in these conditions, to detect or measure {sup 241}Am. III - The equipment makes possible also: - the absolute calibration of a pure {sup 241}Am source - {sup 237}Np measurements - simultaneous measurements of {alpha}, {beta} and {gamma} activities in solid samples in various forms. IV - The assembly includes a small-size proportional counter operating in conjunction with a {gamma} probe, together with auxiliary electronic equipment (stabilized high voltages, amplifiers, a coincidence unit, a sealer). (authors) [French] I - Une methode de mesures par coincidences {alpha} {gamma} est utilisee pour des mesures d'activite de {sup 241}Am en presence d'activite {alpha} (due au Pu) importante. -La sensibilite de l'appareillage permet de deceler: moins de 10{sup -7} {mu}C {sup 241}Am dans les activites {alpha} Pu plusieurs centaines de fois plus importantes. II - Le meme appareillage a ete utilise pour des mesures {alpha} sur des sources emettrices {alpha} en presence d'activites {beta} et {gamma} tres importantes. En particulier des mesures d'activite {alpha} sur des echantillons de poudre sont exposees. Il est meme possible, dans ces conditions, de deceler ou mesurer {sup 241}Am. III - L'ensemble permet egalement: - l'etalonnage absolu d'une source de {sup 241}Am pur - des mesures de {sup 237}Np - des mesures simultanees d'activites {alpha}, {beta} et {gamma} dans des echantillons solides

    In the following report one can find first a short general view on the present situation of our knowledge concerning the nuclear fission process, namely on the nucleus going through the saddle-point. Then there are some aspects connected with the excitation energy of the fissioning nucleus. The measurements made at Saclay on the fast neutron fission cross-section of U{sup 233}, U{sup 235}, Pu{sup 239}, U{sup 238} are described at the beginning of this work. It appears that for U{sup 233} there is some characteristic shape modulation of the cross-section curve, in relation with the collective excited state of the deformed nucleus at the saddle-point. Good evidence of this is also given by the study of the relative fission rate with emission of long-range particles; it appears also that this ternary fission rate does not change substantially for neutron between thermal energy and 2 MeV, but that is very lower for the compound nucleus U{sup 239} than for even-even compound nuclei. At the end there are some experiments on the strong 4,5 MeV gamma-ray originated by slow neutron absorption in U{sup 235}. Time-of-flight device is used to establish that this 4,5 MeV gamma-ray seems mostly connected with radiative capture. (author) [French] Le present travail debute par un apercu de l'etat actuel de nos connaissances sur le processus de fission nucleaire, notamment sur le passage par le point-seuil. Puis sont evoques des aspects lies au niveau d'energie d'excitation auquel est porte le noyau qui subit la fission. Les mesures de sections efficaces de fission induite dans {sup 233}U, {sup 235}U, {sup 239}Pu et {sup 238}U par des neutrons rapides effectuees a Saclay sont decrites en premier lieu; elles font apparaitre pour {sup 233}U une ondulation caracteristique du role des etats collectifs d'excitation du noyau deforme au point-seuil. Des experiences sur la fission avec emission de particules de long parcours confirment cet aspect tout en demontrant que la frequence

    Full Text Available Les recherches sur l’énonciation, en l’occurrence celles appartenant au courant Ducrot, à l’école dit de Genève comme à l’école dite scandinave (portant le sigle « Scapoline », pour n’en mentionner que quelques-unes, donnent depuis quelques décennies de remarquables résultats portant sur la dimension polyphonique et argumentative du langage, sur le jeu discursif des points de vue et des êtres discursifs, de la prise en charge énonciative et du statut assertif (assertion/présupposition/supposition, comme sur le fonctionnement des différents types de marqueurs dits « discursifs ». La contribution de Henning Nølke, donnée lors du CMLF organisé en 2008 à Paris, brosse brillamment l’historique et l’élaboration ultérieure de ce courant. Nul doute que les résultats de bon nombre de ces recherches appartiendront dorénavant aux acquis descriptifs de notre science, qu’il s’agisse du discours rapporté, de la négation, des marqueurs de par exemple la concession ou la causalité. Cependant, il me semble que cette théorisation énonciative, pour heuristiquement valable qu’elle soit – ce qui est indéniable– rencontre parfois des problèmes lorsqu’elle est confrontée avec d’autres dimensions de la description du sens discursif, et testée dans «... le patient travail de confrontation minutieuse des outils avec le réel (en l’occurrence les textes dont ils sont censés rendre compte » (Alain Rabatel, 2010 : 109. C’est pourquoi dans cette communication j’aimerais discuter, à partir d’une enquête portant sur la distribution des marqueurs causaux dans plusieurs genres discursifs, deux problèmes de l’approche énonciative : sa rencontre avec la structure dite informationnelle et la prise en charge énonciative dans un cas bien précis, notamment certaines structures appositives.

    bouillant permettant de calculer les pertes de pression sans discontinuite du coefficient de frottement au debut de l'ebullition franche. La comparaison avec l'experience est satisfaisante. On a etudie les diverses formes que peut presenter la perte de pression totale dans un canal bouillant en fonction du debit. Des singularites sont observees aux vitesses tres faibles et tres fortes. 3 - CALEFACTION (burn out): En regime etabli, on montre que dans un canal a chauffage uniforme le flux de calefaction en fonction du titre de sortie est en general independant de la longueur. Lorsque la calefaction est la consequence d'oscillation de debit, on compare les conditions de calefaction a celles obtenues en regime etabli. On a etudie le flux de calefaction a la suite d'un chauffage uniforme 'en echelon' dans un canal contenant de l'eau sans mouvement. Le flux comporte un maximum en fonction de la sous saturation. On a examine l'influence de la geometrie et de la nature du metal. 4 - OSCILLATIONS DE DEBIT: Sur une boucle a faible pression (8 atm) on a cherche l'influence de divers parametres sur les seuils d'apparition et sur les periodes d'oscillations de debit dans un canal bouillant. On enumere quelques aspects nouveaux de ce phenomene complexe observes a cette occasion. (auteurs)

    Full Text Available Both in the Spanish legal system as, in general, in comparative law, there are two distinct approaches to gender violence. On the one hand, there are supporters of “victim choice”, on the other hand, an approach supporting the benefits of the implementation of no-drop policies might prevail. In the Spanish legal system, both of these approaches coexist and this article aims to examine this. Moreover, in this paper, the author underlines in particular the difficulties coming from the numerous refusals to report such violence and from the frequent retractions of the victims of this kind of crime. Tant dans le système juridique espagnol que, en général, dans le droit comparé, il existe, en matière de violences liées au genre, deux positions : d’un côté, certains sont partisans d’une approche dite victim choice, de l’autre quelques-uns préfèreraient appliquer celle appelée no–drop policies. Dans le système juridique espagnol, ces deux positions coexistent et cet article a comme objectif de les examiner. En outre, dans ce texte, l’auteur souligne tout particulièrement les difficultés dues aux nombreux refus de déposer plainte et aux rétractations fréquentes des victimes, fréquents dans le cadre de ce type de violence.

The economic aspects of the main technical problems entailed by these developments are discussed: loading and unloading machines, blowers etc... (authors) [French] Dans une premiere partie, on situe l'interet economique de l'utilisation de l'uranium naturel comme combustible. Cet interet reside a la fois dans le nombre limite et la simplicite relative des operations de mise en forme des elements combustibles, dans le faible cout du produit fini par kwh et dans les immobilisations modestes en capital qu'implique ce cycle par rapport ou cycle de l'uranium enrichi. Tous ces elements permettent de reduire le caractere aleatoire des evaluations des couts, particulierement marque dans le cas de l'uranium enrichi, en raison de la complexite de son cycle et des incertitudes concernant le prix du plutonium. Enfin, la diversite des sources d'approvisionnement en concentre d'uranium naturel opposee au quasi monopole actuel de la separation isotopique, et le faible cout du stockage de ce concentre, offrent des garanties en matiere de securite d'approvisionnement et d'independance economique et politique appreciables par rapport a l'uranium enrichi. En ce qui concerne l'ensemble des capitaux immobilises, on montre que si le cout des centrales au graphite-gaz est plus eleve que celui des centrales eau legere pour certaines gammes de puissance, ce resultat est fortement nuance des que l'on fait intervenir dans un souci d'independance nationale le cout de l'equipement de production des combustibles de l'une et l'autre filiere. Enfin, le cout marginal de la puissance du reacteur au graphite est faible, ses limitations technologiques ont considerablement recule (grace en particulier a l'utilisation du beton precontraint). On sait que la tendance actuelle est a l'accroissement de la puissance unitaire des

    In this Thesis we study several aspects of potential scattering in non-relativistic quantum mechanics. In the first part, we study the concept of time delay. More precisely, after an elementary introduction to the theory (chapter I), we clarify in chapter II the role played by the localizing regions in the definition of global time delay. In chapter III, we generalize the concept to arbitrary conditions of observation for the scattered particle (conditional time delay). In chapters IV and V, ...

    Full Text Available L’auteur met en place des observations et développe des analyses sur le statut des personnages de fiction, mettant à contribution les ressources de l’histoire, de la littérature, de la sémiotique, de la logique et de la narratologie. De quelle vie particulière vivent les personnages de roman, qui fait que nous sommes capables de les tenir pour plus réels que des personnages réels, et que nous sommes enclins à éprouver les sentiments qu’ils éprouvent, même si nous savons qu’ils n’existent pas ? Comment ces personnages de fiction existent-ils, selon quelle « partition » leur existence se développe-t-elle au point d’interférer avec la nôtre ? L’interrogation porte sur la nature de ce flux émotionnel qui s’écoule du lecteur vers les personnages de fiction et les investit de valeur, sur ce qui se projette de la vie vers le roman, entraînant avec lui le lecteur qui se trouve de la sorte impliqué malgré lui dans l’histoire, et se trouve pris dans le mécanisme de l’identification et de la vie fictive.Some commentaries about fiction charactersPutting into form a number of observations and developing an analysis on the status of fiction characters, the author draws on resources coming from history, literature, semiotic, logic et narration. What is that particular life lived by fiction characters that enable us to consider them as being more real than real characters, and to experience the feelings that they experience, even though we know that they do not exist? How do these characters exist? In other words, according to what “script” does their existence develop to the point of interfering with ours? The questioning centres on the nature of the emotional flux which flows from the reader towards the fictional characters thus giving them value, and on what it is which is projected from real life towards the novel and which is capable of sweeping up the reader who, without having particularly intended to do

    Perez-Milan, Hernan

    1958-05-15

    As sulphite appears to be an intermediate substance in the degradation of sulphur-containing amino acids, and has an important metabolic role, notably for plants, this research thesis aims at comparing transformations which may occur for a same chemical compound (the sulphite) in various organisms belonging to different species or kingdoms. More particularly, the author studied the formation of sulphite in vegetal tissues, and the oxidisation of sulphite into sulfate within these tissues. In vitro experiments have been performed with oat, while in vivo experiments have been performed on tobacco plants [French] Le sulfite apparait comme une substance intermediaire de la degradation des acides amines soufres. Son role dans la biosynthese de certains d'entre eux, problematique chez les mammiferes, est certain chez les oiseaux, qui, a cet egard, se comportent comme des autotrophes partiels, puisqu'ils reduisent le sulfate en sulfite. On s'apercoit ainsi qu'un degre d'evolution moindre confere au sulfite une importance metabolique plus grande. On peut s'attendre a trouver chez les vegetaux un role encore accru pour le sulfite. Le present travail entre dans ce cadre d'etudes comparees des transformations que peut subir un meme type de compose chimique: le sulfite, dans divers organismes appartenant a des especes ou a des regnes differents. Les donnees acquises exposees ici auront trait aux deux points suivants: I - La formation du sulfite dans les tissus vegetaux, II - L'oxydation dans ces tissus, du sulfite en sulfate. L'avoine nous a servi comme materiel de depart pour les experiences faites in vitro. Cette plante presente en effet l'avantage de se bien cultiver en toutes saisons, de se broyer facilement, et d'etre depourvue au maximum de mucilages, de resines, substances genantes pour l'analyse ulterieure. Les essais faits in vivo, ont mis en oeuvre des plants de tabac, qui permettent une nutrition par le petiole ou par la tige particulierement aisee.

    The report describes the principal requirements for gamma units intended for various purposes. Several methods of calculating the dose fields for various forms of irradiators are given, as well as graphs, nomograms and formulae to estimate the amount of gamma-ray dose absorbed by the irradiated object from cobalt-60 and caesium-137. Some of the calculated data have been confirmed by experiment. The advantages of irradiators of various geometry employed in experimental and commercial units are discussed. The irradiation technique for various objects is analyzed and the optimum irradiation conditions (radiation utilization factor, dose field homogeneity, etc.) are discussed. Several rational shielding systems are suggested to simplify irradiation process and recharging, and to reduce the cost of design and operation. (author) [French] Resume Cette communication expose les conditions fondamentales auxquelles doivent satisfaire les installations emettrices de rayonnement gamma, destinees, a divers usages. Elle explique certaines methodes pour le calcul des champs recevant une dose determinee en fonction de la forme du dispositif d'irradiation; elle contient des courbes, des nomogrammes et des formules permettant de calculer la valeur de la dose de rayons gamma du cobalt-60 et du cesium-137 recue par l'echantillon soumis a l'irradiation. Certaines donnees etablies par le calcul ont ete confirmees experimentalement. On examine l'utilite d'employer des dispositifs d'irradiation de configurations variees dans des installations experimentales et des installations industrielles. Les auteurs examinent la technologie de l'irradiation de divers echantillons en vue de choisir les conditions optimales d'irradiation (facteur d'utilisation du rayonnement, uniformite du champ recevant une dose determinee, etc.).

    The results given in this paper are based on the fact that the best way of burying fission products is to incorporate them in vitrified fused blocks containing these fission products. The physico-chemical bases of the transformation of liquid waste into solid blocks are shown. The thermogram of this process is presented and the analysis of its characteristics given. The conditions of fusion of the vitrified mass, in particular those contributing to the fixation of radioactive aerosols, are shown. Some results of studies on the chemical state of radioactive fission products in the solid mass in connexion with the leaching of their radioactivity are given. In conclusion, the results of calculations of the temperatures up to which the radioactive blocks may be heated according to their characteristics are presented.

    Full Text Available L’alimentation dans les négro-cultures en général et chez les Bulu en particulier revêt une importance qui va bien au-delà de la satisfaction organoleptique. En effet, elle intervient dans la société comme un fait social total permettant de l’appréhender sous l’angle politique, économique, médical, religieux, artistique, juridique, linguistique. Du point de vue linguistique, les proverbes constituent un espace propice à la démonstration des représentations autour de l’aliment. Utilisés pour illustrer une situation, donner une leçon ou encore appuyer un discours, les proverbes sont un canevas linguistique dont on ne peut se passer dans les joutes oratoires. Pour ce qui concerne est des proverbes alimentaires, on peut se rendre compte qu’ils permettent d’observer comment les Bulu appréhendent le monde et montrent de ce fait la société dans sa dimension holistique. Cet article s’attèle à une analyse anthropologique de quelques proverbes alimentaires de la socioculture bulu. Ces parémies font intervenir la vision bulu de l’organisation politique, de l’économie, des relations de parenté, de la diplomatie, de l’education, de la mort, de la justice, de la construction de la personnalité,etc. Feeding in negro-cultures generally and particularly on Bulu’s people have an importance which goes beyond the biological needs. In fact, it intervenes in this society as a social total fact and permits to apprhehend it on political, economical, medical, religious, artistic, juridical, linguistic angle. From the linguistic point of view, proverbs constitute a favorable space to the demonstration of representations on food. Used to illustrate a situation, to give a learning or to support a speech, proverbs are a linguistic framework which is not possible to avoid during verbal sparrings. Concerning food proverbs, it can be realized that, they permit to observe how Bulu’s people apprehend world and show society in this

    Full Text Available Au Brésil comme au Maroc, le secteur agricole est marqué par des différences extrêmes en termes de taille d’exploitation, ainsi que de niveaux d’équipement, de capitalisation et de techniques. L’article présente la politique brésilienne d’appui à l’agriculture familiale, et quelques éléments de comparaison avec les choix faits au Maroc. Les politiques agricoles brésiliennes proposent depuis une vingtaine d’années un appui spécifique aux exploitations familiales, avec notamment la constitution d’un ministère spécifique. De nombreux dispositifs d’appui à l’agriculture familiale ont été mis en place, dont notamment des crédits à taux préférentiel et des programmes d’achat de denrées agricoles pour les institutions publiques (écoles, hôpitaux, etc.. Dans les zones rurales particulièrement fragiles, des dispositifs permettent une coordination entre l’ensemble des politiques publiques concernant ces zones. Enfin, la conception et la mise en oeuvre de ces politiques publiques se font avec une forte implication des syndicats agricoles. Les politiques publiques brésiliennes et marocaines reconnaissent la dualité du monde agricole, mais cette dualité est définie par zone au Maroc, tandis qu’elle est fondée sur des caractéristiques explicites des exploitations au Brésil. Dans les deux pays, le coeur des politiques publiques d’appui aux exploitations familiales porte sur l’aide à l’investissement. Au-delà de ce coeur commun, les politiques brésiliennes ont plus spécifiquement développé des approches au niveau des territoires locaux et associent plus fortement qu’au Maroc les organisations professionnelles agricoles représentant l’agriculture familiale dans la conception de l’action publique. La comparaison des politiques agricoles au Maroc et au Brésil sur quelques éléments permet de souligner la forte étendue des choix qu’il est possible de considérer, pour définir des

  11. Deux types de prédication, avec ou sans sujet: quelques illustrations colombiennes

    Directory of Open Access Journals (Sweden)

    1994-01-01

    Full Text Available Toutes les langues ne suivent pas dans leurs énoncés-phrases la division morpho-syntaxique Sujet / Prédicat. Plutôt que d’organiser le contenu de l’énoncé à partir d’une des entités dont on parle, certaines langues partent de ce qui est dit de ces entités, que cela soit appelé prédicat ou relation prédicative ou fonction prédicative, etc... Cette différente perspective se manifeste alors en un schéma de construction qu’on peut appeler “schéma holophrastique”, distinct du schéma “subjectal” ou schéma sujet / prédicat. L’article cherche à mettre à l’épreuve l’intérêt de cette distinction de schémas en en montrant l’usage dans quelques langues amazoniennes dont certaines sont présentées dans ce recueil. On voit que l’opposition entre schémas prédicatifs renvoie à une dimension qui doit être maintenue distincte de l’aspect ou de la voix, même si ces trois dimensions s’entrecroisent constamment. PREDICACIÓN CON SUJETO, PREDICACIÓN SIN SUJETO: EJEMPLOS COLOMBIANOS. No todas las lenguas siguen en sus oraciones la división morfosintáctica Sujeto vs. Predicado. En vez de organizar el contenido de la oración a partir de una de las entidades de las cuales se está hablando, algunas lenguas prefieren partir de lo que se dice de estas entidades, llámese predicado, relación predicativa, función predicativa, etc... Esta diferencia de punto de partida o de perspectiva se manifiesta en un esquema de construcción que llamamos “esquema holofrástico”, bien diferente del esquema sujeto/predicado llamado también “esquema subjetal”. Este artículo trata de poner a prueba el interés de esta oposición de esquemas mostrando su uso en algunas de las lenguas amazónicas, algunas de las cuales hacen parte de este compendio. Se ve por ejemplo que los esquemas predicativos remiten a una dimensión semántica distinta de la del aspecto o de la de la voz aún cuando estas tres dimensiones se entrecruzan

    In order to take the specific character of a nuclear emergency situation into account, France has developed planning tools within the so-called Crisis National Organisation (ONC, organisation nationale de crise). This organisation involves public bodies, agencies and companies. Thus, intervention specific plans (PPI, plans particuliers d'intervention) are included in the ORSEC general arrangement. The assessment of geographical and chronological consequences of a nuclear accident has lead to the definition of two main categories of measures, depending on the fact they are immediately or progressively applied. They involve the intervention of specialised means. This report also indicates how new measures have been introduced in the ORSEC arrangement to manage the post-accident phase. The author also outlines that crisis communication must also be prepared and tested

Celles-ci, assemblées de façon originale, façonnent une région caractéristique qui est à la fois la plus riche du royaume de Thaïlande et la plus éprouvée par une situation politique et militaire, instable depuis des décennies.This article is based on a journey through Southern Thailand, where the population, mostly Jawi, Malay, and Muslim, displays Siamese, Chinese, and Mon cultural features as well as some ancient Proto-Malay traits. It offers a description of some of its cities and towns, marked by the region's particular history and by urbanistic and architectural forms locally prominent for cultural, religious, economical, and political reasons. It shows that Southern Thailand is a complex crossroads of various civilizations and cultures, combined in a unique manner to form a specific domain, which is both the richest region of the kingdom of Thailand and one that has been, for decades on end, most stricken by an unstable political and military situation.

    Enclosed or intra-continental seas should be distinguished from lakes, because the systems of the international law of the sea and international water- law differ from each other. The definitions of the enclosed sea used in the literature are not satisfactory and in the paper a new and more appropriate definition is proposed. The main sources of the international law of the sea are four Conventions adopted by the United Nations Conference on the Law of the Sea held at Geneva in 1958. Many of the problems concerning the Baltic are also characteristic of other intra-continental seas. In the paper reference is made to these problems and to the considerations that render the provisions of the Conventions on the Law of the Sea inadequate for the case of the enclosed seas. With regard to the prevention of pollution of the sea and the disposal of radioactive wastes, the rules of international law are still undeveloped. In the paper mention is made of the aspects that should be considered when drawing up regulations and taking measures for the prevention of pollution, especially of the enclosed seas. (author) [French] Il faut distinguer les mers fermees ou intracontinentales des lacs, car le droit maritime international s'applique aux premieres et non aux deuxiemes.

  20. Quelques aspects de l'évolution géomorphologique quaternaire du haut bassin du Magdalena (Colombie

    Directory of Open Access Journals (Sweden)

    1974-01-01

    Full Text Available Le bassin supérieur du Rio Magdalena présente les caractéristiques suivantes: 1 L'allure générale du bassin montre une influence très nette de la tectonique. Il s'est développé grâce à la présence d'un ensemble de blocs affaissés relativement les uns par rapport aux autres et entourés de blocs soulevés qui forment les limites du bassin. Dans certains cas des édifices volcaniques se superposent à ces blocs (Nevado del Huila, parâmes de Las Papas, par exemple. 2 Dans certaines parties du bassin (Nevado del Huila, environs du rio Mazamoras, et de Pitalito, le volcanisme s'est développé durant tout le Quaternaire. De la sorte, en général on observe un paroxysme volcanique durant la période d'accumulation de QIII dont la position géomorphologique est très semblable à celle du Mindel européen (Nebraska d'Amérique du Nord. Les matériaux volcaniques ont ainsi contribué à la mise en place de l'accumulation QIII mais cette accumulation n'est pas un produit du volcanisme car on l'observe bien développée dans des vallées ou il n'y eut aucune activité volcanique à cette époque. Ainsi, la mise en place du remplissage QIII provient d'une oscillation climatique. La granulométrie très grossière du matériel QIII provient de la combinaison du volcanisme et de cette oscillation climatique. 3 Dans le bassin, les événements morphogénétiques les plus saillants sont les suivants: - une incision extrêmement profonde des talwegs des avant l'accumulation de QIII cette incision a atteint au moins le niveau des rivières actuelles - la fossilisation des cañons incisés durant cette phase par l'accumulation très épaisse du matériel QIII. - postérieurement, a fonctionné une tendance très générale à l'incision uniquement interrompue par les phases d'accumulation QI et QII. Actuellement, cette incision n'est toujours pas arrivée au niveau atteint avant l'accumulation de QIII. Durant cette période d'incision des rivières, postérieure à QIII se sont développés divers phénomènes de surimposition comme celui de El Estrecho. - La tectonique à la suite du jeu différentiel des blocs commande la disposition des divers remplissages quaternaires, la position respective des terrasses qu'ils forment et leur altitude relative. Dans la zone de Garzón ou de La Plata, correspondant à des blocs affaissés, l'échelonnement des terrasses diminue. Au, contraire, sur les blocs soulevés comme près de San Agustin et d'Isnos ou aux environs de Salado Blanco, l'épaisseur de QIII est maximale, atteignant 500 m à Salado Blanco, ce qui a permis une gigantesque fossilisation des vallées par cette accumulation. La cuenca alta del R. Magdalena se caracteriza por los siguientes rasgos morfogenéticos: (1 El diseño general de la hoya demuestra una influencia muy nítida de la tectónica. Es originado por la presencia de un conjunto de bloques relativamente hundidos, rodeados por los bloques levantados, los cuales forman sus divisoras. A veces, edificios volcánicos se superponen sobre ellos (Nevado del Huila, Páramo de las Papas por ejemplo. (2 En algunas partes de la hoya (Nevado del Huila, cercanías del R. Mazamorras, de Pitalito, el volcanismo ha actuado durante todo el Cuaternario. Por tanto, en general, se identifica un paroxismo durante el período de acumulación de QIII cuya posición geomorfológica es sumamente parecida con la del Mindel europeo (Nebraska de Norte-América. Evidentemente, los productos volcánicos han contribuido en la edificación de la acumulación QIII. Pero ella no es un producto del volcanismo por encontrarse bien desarrollada también en valles donde no hubo ningún volcanismo en esa época. Por consecuencia la edificación del relleno QIII es originada por una oscilación climática. La granulometría muy gruesa del material de QIII resulta de la combinación del volcanismo y de dicha oscilación climática. (3 En la cuenca, los mas notables acontecimientos morfogenéticos son los siguientes: - Una incisión sumamente profunda de los talvegues luego antes de la acumulación de QIII. Ella llegó por lo menos al nivel alcanzado por los ríos actuales. - La sepultación de los cañones entallados durante esa fase por la acumulación muy espesa del material QIII. - Posteriormente, funcionó una tendencia general a la incisión interrumpida por las fases de acumulación QII y QI. En el presente, la incisión no ha generalmente llegado de nuevo al nivel alcanzado antes de la acumulación de QIII. En el transcurso de ese encajonamiento de los ríos posteriormente a QIII se desarrollaron varios fenómenos de surimposición como en el Estrecho. - La tectónica, por el intermedio de los movimientos diferenciales de bloques, origina la disposición de los varios rellenos cuaternarios, la posición mutua de las terrazas que ellos forman y su altura relativa. En el área de Garzón o de La Plata, que coinciden con bloques hundidos, el escalonamiento de las terrazas es mínimo. Al contrario, en los bloques levantados, como cerca de S. Agustín y de Isnos o alrededor de Salado Blanco, el espesor de QIII es máximo, llegando a los 500 m. en Salado Blanco, lo que ha permitido una sepultación gigantesca de los valles por esa acumulación.

    Full Text Available About some cropping systems of soybean (Glycine max. L. in Congo : first results. Field experiments were conducted to assess the response of soybean Glycine max cv. FN3 to N fertilization and inoculation respectively. In the first experiment, the effects of different levels of N fertilizer (0 ; 20 ; 40 and 80 kg N/ha with or without liming were studied. Soybean podyield were related to N fertilization only when liming was added to the soil In the second one, the effects of four Bradyrhizobium japonicum strains F A3 ; 3-40 ; SA 1 and G3S on nodulation and yields were also studied. Inoculation has significant effect on nodulation and plant top dry weight at full bloom, and seed yield at harvest when compared to the control. However, the Bradyrhizobium japonicum strains tested had various symbiotic effectiveness on Glycine max cv. FN3. In addition, soybean plants inoculated with G3S strain and those fertilized with 100 kg N/ha produced similar seed yield. Our study illustrated that G3S strain had the better adaptability in environmental conditions of Congo soil.

    As modern techniques develop more elaborate machines, and make their way towards higher and higher temperatures and pressures, the thermal stresses become a matter of major importance in the design of mechanical structures. In the first part of this paper, the authors examine the problem from a theoretical standpoint, and try to evaluate the aptitude and limitation of mathematical techniques to attain the quantitative values of thermal stresses. This paper deals mainly with the experimental methods to measure thermal stresses. The authors show some examples relating to nuclear reactors. (author)Fren.

    A number of equipments or processes allowing to detect uranium or plutonium in industrial plants, and in particular to measure solution concentrations, are studied here. Each method has its own field of applications and has its own performances, which we have tried to define by calculations and by experiments. The following topics have been treated: {gamma} absorptiometer with an Am source, detection test by neutron multiplication, apparatus for the measurement of the {alpha} activity of a solution, fissionable matter detection by {gamma} emission, fissionable matter detection by neutron emission. (author) [French] On examine ici plusieurs appareils ou procedes qui permettent de detecter l'uranium ou le plutonium dans les installations industrielles, et en particulier de mesurer les concentrations de solutions. Chacune des methodes a son domaine d'application et ses performances, qu'on a tente de definir par le calcul et par des experiences. Les sujets traites sont les suivants: absorptiometre {gamma} a source d'americium, essais de detection par multiplication neutronique, appareil de mesure de l'activite {alpha} d'une solution, detection des matieres fissiles par leur emission {gamma}, detection des matieres fissiles par leur emission neutronique.

  9. Quelques aspects de la géochimie organique dans la prospection des hydrocarbures Several Aspects of Organic Geochemistry in Prospection for Hydrocarbons

    Full Text Available La classification, d'après la composition des huiles brutes, permet maintenant de reconnaître des origines semblables ou différentes. Dans certains cas, les corrélations non seulement entre indices et accumulations, mais entre roches mères et accumulations sont devenues sûres. L'étude, selon un fil logique du devenir des composés de la matière organique vivante, morte, fossilisée puis diagénisée, a permis de préciser l'origine organique des pétroles mais encore de lier la composition de ceux-ci aux types dominants de matière organique des bassins sédimentaires, donc de fixer les conditions de sédimentation, les environnements les plus favorables à l'accumulation et la préservation de matière organique pétroligène. Cependant, la contribution la plus importante de la géochimie organique à l'exploration est certainement d'avoir pu fixer, dans un premier temps, une fourchette de température, puis de température et de durée : le facteur thermo-temporel de naissance de production maximale puis de conservation des hydrocarbures liquides : la fenêtre à huile potentielle. Plus récemment la géochimie des gaz hydrocarburés a pu montrer que cette fenêtre à huile était encadrée par la génération de gaz légers. Ce développement récent remet en valeur des objectifs de prospection abandonnés ou classés sans intérêt. Cependant par essence même la géochimie organique, comme la majorité. des sciences qui utilisent le laboratoire, donne des résultats ponctuels : ceux-ci ne trouvent toute leur signification que si les échantillons géologiques sont bien situés dans la configuration géologique à laquelle ils appartiennent. Organic geochemistry has made great strides, thanks in particular to the range of analytical tools, often in the forefront of technological progress, which have been developed for medical and biochemical research. Classification according to the composition of crude oils now make it possible to know whether origins are similar or different. In some cases, correlations not only between shows and accumulations, but also between source rocks and accumulations, have become certain. Study along logical lines of the development of living, dead, fossilized and then diagenized organic matter compounds, has made it possible to define the organic origin of petroleum and also to associate its composition with the dominant types of organic matter in sedimentary basins, and hence to determine sedimentation conditions and the most favourable environment for the accumulation and preservation of petroligenic organic matter. However, the greatest contribution of organic geochemistry to exploration has certainly been its ability to determine, in the initial stage, a range of temperature, and then of temperature and duration: the heat-time factor generating maximum production and then conservation of liquid hydrocarbons: the potential ail window. More recently, geochemistry of hydrocarbon gases was able to demonstrate that thisoil windowwas surrounded by the generation of light gases. This recent development has refocused attention on prospecting objectives which had been abandoned or deemed without interest. However, organic geochemistry by its very nature and like most laboratory-based sciences, yieldsspotresults; these will not be fully significant unless the geological specimens are properly situated in the geological configuration to which they belong.

    Zirconium phosphate has been studied with a view to using it as an ion exchanger: the first objective was to develop a method of preparation easy to apply and also reproducible. To this end, several tests were carried out varying the molar ratios of phosphorus and of zirconium. Some physical properties such as the diffraction of X-rays were examined. The work then involved certain chemical properties, particularly the percentages of free water and structural water given by the loss on calcination, the Karl-Fisher method and the weight losses by thermogravimetry. Finally an attempts was made to apply the exchanger to the separation of alkaline ions. The static tests showed that the order of fixation of these ions was Cs{sup +} > Rb{sup +} >> K{sup +} > Na{sup +}. Tests with columns showed that Na{sup +} and K{sup +} were easily separable, as was the Rb{sup +}-Cs{sup +} mixture, this last pair being fairly difficult to dissociate.

    Full Text Available L’organisation nationale en matière d’évaluation et de gestion des risques est en cours de modifications depuis quelques années. Organisée par une loi en 1998, la création d’agences pour la sécurité sanitaire des aliments, des produits de santé et de l’environnement a marqué une étape. D’autres domaines sont en cours de réorganisation comme la sûreté nucléaire et la radioprotection. La mise en oeuvre de la directive SEVESO II peut aussi influer sur la gestion des installations industrielles classées dites « SEVESO ». Des « événements » comme la crise de la vache folle ou celle du sang contaminé ont joué un rôle dans les évolutions, mais l’émergence de nouveaux principes de gestion des risques au sein de la communauté internationale a aussi influé fortement sur les choix faits et les discussions. Le travail présenté ici est un travail préliminaire, qui visait à identifier les grandes lignes des réponses apportées dans les différents domaines à des questions comme celles du rôle des différentes institutions en matière d’évaluation et de gestion. L’approche comparative suivie ici est trop globale pour que tous les éléments de chaque système réglementaire soit décrit et certains aspects sont simplifiés. En revanche, ce type de comparaison met en lumière des contrastes notables quant aux solutions trouvées pour articuler le travail d’évaluation des risques et les prises de décision relevant des autorités.

    2010-07-01

    Full Text Available Le présent texte explore l’articulation entre l’empowerment et la diversité culturelle, et notamment les voies prometteuses du jumelage entre ces deux termes. L’apport de la philosophie de Charles Taylor conjuguée aux récentes théories du fédéralisme permet de porter un regard nouveau sur la thématique des revendications identitaires en milieu urbain et d’esquisser des solutions institutionnelles pour répondre au double défi posé par le pluralisme culturel et de la nouvelle configuration économico-politique sous-tendant la mondialisation. Malgré ses aspects positifs, cet article entend montrer, dans le sillon des travaux de Bernard Jouve, les limites et l’utilisation équivoque que l’on peut faire de l’empowerment, qui sert parfois à justifier un désengagement de l’État-providence en faveur des populations les plus démunies, et qui ne présente pas toujours les garanties nécessaires pour lutter contre les discriminations survenant au sein des Minorities within Minorities.This article explores linkages between empowerment and cultural diversity largely defined, and at times a promising convergence between the two notions. Charles Taylor’s contribution to current theories of federalism allows us to cast a rejuvenated  look on cultural claims in urban centers and to sketch institutional avenues to face the dual challenge posed by cultural pluralism and the new socio-political configuration underlying globalization. In spite of some very positive aspects, and following Bernard Jouve’s intellectual insights, this text illustrates the extent to which the notion of empowerment can also be deceiving as it might add limitations for weaker communities, and create new hurdles as the undermining of the welfare state has showned. In addition, empowerment does not always provide guarantees to counter discrimation as the case of «Minorities witin Minorities» reveal.

    Full Text Available This article explores some of the strategies applied by consumers for making-do during the Second World War in Norway. By reducing waste, using various substitutes and exploiting underused natural resources such as wild plants, birds, and alternative marine sources of nutrition, Norwegian consumers adapted their diet to a situation of food scarcity. However, their everyday consumption was primarily governed by the regulatory framework installed for dealing with the crisis, namely the rationing system. By 1942, almost all common foods had been placed under rationing. Despite of the many bureaucratic inconveniences of this system, it was largely supported by consumers, who accepted it as a socially just mechanism for distributing scarce resources. The article brings up the question of how far the willingness of consumers to accept rationing was a unique experience of the war, or whether one might imagine a similar design for purposes of sustainable consumption.Cet article explore quelques unes des stratégies utilisées par les consommateurs pour survivre pendant la 2è guerre mondiale en Norvège. En limitant les déchets, en utilisant des produits de substitution ainsi que les ressources de la nature telles que plantes sauvages, oiseaux et aliments marins alternatifs, les consommateurs norvégiens ont pu adapter leur alimentation à cette période de pénurie alimentaire. La nourriture quotidienne était toutefois essentiellement encadrée par la réglementation mise en place afin de faire face à la crise, c’est à dire le système de rationnement. En 1942, presque tous les aliments étaient rationnés. En dépit de ses nombreux inconvénients administratifs, le rationnement fut quand même soutenu par les consommateurs, qui l’acceptèrent comme un système socialement équitable pour la distribution des maigres ressources.

    The chemical effect of ionizing radiations on a certain number of gaseous systems is described. Under the influence of radiations from a reactor, NH{sub 3}, is decomposed to nitrogen and hydrogen in stoichiometric proportions. Formation of N{sub 2}H{sub 3}, particularly could not be detected. Under a slow neutron flux the reaction {sup 14}N (n, p) {sup 14}C constitutes the main source of decomposition energy. Direct recombination of H, and N, has been brought about under the influence of radiation. The radiolysis of NH{sub 3}, occurs by a complex mechanism; and the kinetics follow a law of the order of about 2.5 which increases with the decomposition rate. The decomposition of hydrogen sulphide is appreciably faster than that of NH{sub 3}. Hydrogen is the only gaseous product of the reaction. The sulphur, which is deposited on the walls of the ampoules, is clearly visible to the naked eye. Up to the present decompositions up to 84 per cent have been obtained. The influence of the reaction {sup 32}S (n, p) {sup 32}P is considered. Radiochemical decomposition of nitrous oxide N{sub 2}O takes place with high yields. The reaction is complicated from the beginning by the formation of higher oxides of nitrogen which we identify and measure. Radiochemical decomposition of methane gives quantities of higher hydrocarbons. Certain of these gaseous systems could find applications in the measurement of high doses of radiation. This problem is discussed in the conclusion. (author)Fren. [French] L'effet chimique des rayonnements ionisants sur un certain nombre de systemes gazeux est decrit.

Attestés par plus d’un millier d’inscriptions recueillies dans toute l’Afrique du Nord, depuis la Libye jusqu’aux îles Canaries, ces alphabets sont selon toute vraisemblance les ancêtres des alphabets touaregs actuels. La seule inscription qui ait pu être datée avec un degré raisonnable de certitude est une bilingue libyco-punique, mise au jour sur le site de Dougga (Tunisie, qui daterait de 139 avant J.-C. Il semble que les alphabets libyques existaient déjà alors depuis plusieurs siècles. Leurs créateurs ont emprunté quelques lettres (au moins quatre aux alphabets phénico-puniques. Pour composer les autres lettres, ils semblent avoir eu recours à des procédés géométriques simples qu’on essaie ici de reconstituer.A few hypotheses about the origin of the so-called “Libyan” alphabets are presented. Attested in more than a thousand inscriptions from Libya to the Canary Islands in northern Africa, these alphabets are probably the forebears of the current ones used by the Tuareg. The only inscription that has been dated (139 BCE with a reasonable degree of certainty is bilingual, Libyco-Punic, from Dougga in Tunisia. The “Libyan” alphabets apparently already existed, several centuries earlier. Their creators borrowed a few — at least four — letters from the Phoenician/Punic alphabets; and apparently used simple geometric procedures, which are reconstituted herein, for the other letters.

    An examination has been carried out of non-alloyed uranium samples, having various structural states, cold-worked and recrystallized, as-cast and {beta}-treated, and irradiated at temperatures of between 450 and 600 C and with burn-ups from 1300 to 5500 MW days/metric ton. These samples swelled because of precipitation of the fission gases the porosity thus produced has a morphology depending mainly on the type of deformation to which the metal has been subjected and which is due to in-pile growth. The most homogeneous distribution of pores, and thus that leading to the minimum swelling, is only observed in the material having a marked [010] texture in which the growth and perhaps the thermal cycling introduce little or no strain. For other materials the deformation /swelling association causes a more rapid destruction of the samples either by cracking when the deformation is due to twinning, or by pronounced swelling localized in the bands when deformation is due to slipping. Finally the fission-gas precipitation considerably facilitates, above 500 C, the germination and growth of the intergranular cracks which can then develop at low stresses. (author) [French] On a examine des echantillons d'uranium non allie, de divers etats structuraux, marteles et recristallises, bruts de coulee et traites {beta}, irradies a des temperatures comprises entre 450 et 600 C, et a des taux de combustion allant de 1300 a 5500 MWj/t. Ces echantillons ont gonfle par suite de la precipitation de gaz de fission: la porosite ainsi fournie a une morphologie qui depend principalement des modes de deformation subie par le metal et due a la croissance en pile. La repartition la plus homogene des pores, donc celle qui donnera le gonflement minimum, est observee seulement dans le materiau a forte texture [010] dans lequel la croissance et eventuellement le cyclage thermique introduisent peu ou pas de contraintes. Dans les autres materiaux l'association deformation/gonflement rend plus rapide la destruction des echantillons, soit par fissuration lorsque la deformation opere par maclage, soit par gonflement exagere localise dans des bandes lorsque la deformation se fait par glissement. Enfin la precipitation des gaz de fission facilite considerablement, a partir de 500 C, la germination et la croissance des fissures inter granulaires qui peuvent alors se developper sous de faibles contraintes.

    This report addresses the use of a method which aims at directly measuring quantities of steady iodine involved by the thyroid metabolism in specific physiological conditions. The experiment is based on the use of male rats weighting 180 to 200 g which received an almost iodine-free diet. The daily dose of iodine is administered to each experimental group through beverage under the form of potassium iodide. After a delay, the usual beverage is replaced by a marked one. Iodine renewal by thyroid is monitored in vivo by external detection of radiations emitted by iodine 131. At the end of the experiment, rats are killed, and their blood is collected on heparin, centrifuged and processed to separate mineral iodine and hormonal iodine. Radioactivity is then measured with a scintillator and compared with that of a beverage sample [French] Le but de la methode utilisee est de mesurer directement les quantites d'iode stable mises en jeu par le metabolisme thyroidien dans des conditions physiologiques precises. Les travaux anterieurs ne permettent d'atteindre ces quantites que par des microdosages chimiques longs et delicats. En nous basant sur le principe du renouvellement d'un pool en etat dynamique stationnaire, nous decrivons une cinetique et mesurons en valeur absolue les differents parametres de ce systeme en equilibre.

    After a brief description of the experimental procedure, the curves representing the concentration versus the depth of penetration are presented for the various systems under study. From these curves, it is possible to derive the diffusion coefficient and the activation energy as functions of the concentration. Moreover in the multiphase region, these curves enable one to establish the equilibrium diagram. The growth kinetics of the various zones characterized by their micrographic aspect is also studied and the corresponding activation energies calculated. These activations energies are compared to the ones for the diffusion process at the same concentration. Finally in order to precise the diffusion mechanism, the Kirkendall effect is studied and the Darken intrinsic coefficients calculated. (author)Fren.

    After recalling that the simulation of exchangers poses problems which are often difficult to solve, the author points out that these problems appear first of all when the physical phenomena are described in terms of equations. They appear also during the solving of the equations since expressions which are more and more complex can give rise to unstable electronic structures. These difficulties are developed during the analysis of various types of exchangers and in each case the solutions chosen are given. (author) [French] On rappelle que la simulation des echangeurs pose un certain nombre de problemes souvent difficiles a resoudre. Les difficultes apparaissent d'abord lors de la mise en equations des phenomenes physiques; elles apparaissent ensuite au moment de la resolution, car des formulations de plus en plus complexes peuvent donner lieu a des structures electroniques instables. On developpe ces difficultes en faisant l'analyse de quelques types varies d'echangeurs et l'on indique dans chacun des cas les solutions qui ont ete retenues. (auteur)

    The state of equilibrium between several nuclides in radioactive relationship is determined with accuracy by the fundamental equations of radioactivity. It can be measured physically and expressed in suitable and internationally adopted units; Equilibrium - disequilibrium of uranium-bearing ores is a fairly complex phenomenon but the problem can be much simplified by well-chosen approximations in various practical field cases. The results of radiometric and radiochemical measurements lead to the interpretation of geochemical anomalies and may be used in the qualitative and quantitative estimation of uranium bearing deposits.

    This paper deals with functionals of Brownian motion that appear in various contexts, and with some properties of anomalous diffusion in a one-dimensional random environment. Section 2 explains why path integrals provide a powerful framework to compute probability distribution of functionals of Brownian motion. This approach is used to study winding properties of planar Brownian motion. Section 3 is devoted to an exponential functional of Brownian motion, which arise in particular in the study of transport properties of classical diffusion in a one-dimensional disordered system of finite length. This functional belongs to the field of multiplicative stochastic processes. Cet article porte sur l'étude des distributions de probabilité de quelques fonctionnelles du mouvement brownien qui interviennent dans divers contextes physiques. Le paragraphe 2 présente une méthode d'intégrale de chemin qui relieles distributions de probabilité de certaines fonctionnelles du mouvement brownien, à des fonctions de Green euclidiennes de la mécanique quantique. Cette approche permet notamment d'étudier certaines propriétés d'enroulementdu mouvement brownien plan, qu'il soit libre ou soumis à l'action d'un potentiel extérieur.

    Full Text Available Les facteurs historiques et géopolitiques ont eu, à Genève, une influence notable sur la structure du territoire et la morphologie de certaines localités. A Meyrin par exemple, la création d’un nouvel axe routier a transformé en quelques années un village-rue en village-carrefour. A Malagny, un hameau d’origine médiévale a été presque entièrement détruit au XVIIIe siècle pour faire place à un grand domaine. A Genthod, un modeste village s’est embourgeoisé suite à l’implantation de trois domaines patriciens et les paysans ont accepté de déplacer leur fumier dans une rue secondaire, créée à cet effet. A Chêne, un village a été scindé en deux entités politiques et confessionnelles bien distinctes, tandis qu’à Plan-les-Ouates, le contraste est frappant entre les deux côtés de la rue principale, colonisés à deux époques différentes. Ces quelques exemples relèvent de ce que l’on peut considérer comme de l’aménagement du territoire avant la lettre et démontrent qu’il est impossible de dissocier l’architecture rurale de son environnement et de son histoire.In Geneva, historic and geopolitical factors have significantly influenced the region’s overall structure and the form of particular locals within it. For example, in the course of just a few years, a new road transformed Meyrin from a one-street village into an important commercial crossroad. In Malagny, a medieval hamlet was almost entirely demolished in the 18th century to make way for a grand estate. In Genthod, a farming village was “gentrified” after 3 nobles estates were established around it. The village peasants agreed to move their dung-heaps to a more discreet secondary street, donated by one of the estates for the purpose. In Chêne, a village was divided into two distinct political and religious districts. Finally, at Plan-les-Ouates, there is a strong contrast between the two sides of the village’s main street, which were

    The study of absorption, of distribution in the organism and of the elimination of a medicament has been greatly facilitated by the development of nuclear applications. In effect, the introduction into the molecule of one or several radioactive atoms makes it possible to follow the path and destination of minute quantities of the drug and to thus carry out analyses on the animal within limits of posology close to those of therapeutics. However the qualitative or quantitative methods used have certain limits and they must be compared amongst themselves and with others. Some examples will show : - the importance of the way of administering the drug on the changes in the distribution; - the quite relative selectivity of this latter; - and lastly, the different process involved in the elimination mechanisms.

    The aim of this work is the application of spectrophotometric titrations to the analysis of uranium-containing solutions. We have been led to examine the general principles involved in these titrations, and we give a brief outline of these principles. In the first part we deal therefore with spectrophotometric titrations from a general point of view, examining their fundamental principle, their practical execution as well as the various possibilities of the method. The advantage of the titration are examined, in particular that of lending itself simultaneous determination of two species. The possibility of applying these spectrophotometric titrations to the analysis of uranium-containing solutions is the subject of the second part of this report: the dosage of a few species in uranium (VI) solutions is described. To this second part is added an experimental appendix consisting of a description of the apparatus, as well as of the operational techniques used for certain titrations, in particular those involving solutions containing uranium.

    Plants materials are not so commonly analysed by radioactivation than biological extracts of medical importance. With help of concrete examples, applications of neutrons activation analysis to the determination of some metals (Mn, Cu, Co, Fe, Zn, and K) in plant materials, are proposed. Samples are activated in a swimming-pool reactor at the thermal flux of 5.10{sup 12} n.cm{sup -2}s{sup -1} for a time varying between few minutes and several days according to the element being analysed. The induced radioactivity is measured by spectrometry, with radiochemical separation ( Cu, Co, Fe, Zn and K) or without separation in best cases (Mn,Cu, K). Described dosages are related to: manganese in a graminaceous plant, copper in vine treatments, cobalt, iron and zinc in animal feeding, potassium in a radiological experiment. (author) [French] Les produits vegetaux sont beaucoup moins souvent soumis a l'analyse par activation que les extraits biologiques d'interet medical. En s'appuyant sur des cas concrets, nous proposons des applications de l'analyse par activation neutronique au dosage de differents metaux (Mn, Cu, Co, Fe, Zn, et K) dans la matiere vegetale. Les echantillons sont actives en pile piscine au flux thermique de 5.10{sup 12} n.cm{sup -2} s{sup -1} pendant des temps variant de quelques minutes a plusieurs jours selon les elements a analyser. le comptage de la radioactivite induite est effectue par spectrometrie gamma apres separation radiochimique (Cu, Co, Fe, Zn, et K) ou sans separation dans les cas favorables (Mn, Cu, K). Les dosages decrits concernent: le manganese dans une graminee, le cuivre en viticulture, le cobalt, le fer, et le zinc dans un aliment du betail, le potassium dans une experience de radioecologie.

    Directory of Open Access Journals (Sweden)

    Janik Bastien Charlebois

    2014-04-01

    Full Text Available L’idéal d’objectivité et la quête de vérité sont bousculés par l’arrivée massive de chercheurs universitaires provenant de groupes ayant historiquement connu des discriminations. Contestant la possibilité même d’atteindre l’objectivité et relevant comment la recherche qui s’en réclame a souvent contribué à des injustices sociales, plusieurs de ces chercheurs défendent la légitimité des recherches engagées. Cependant, parmi les débats qui ont suivi, peu se sont consacrés aux implications que revêtent l’affirmation d’un positionnement identitaire qui n’est pas d’emblée visible, tels que ceux d’une personne lesbienne, gaie, bisexuelle, trans, ou encore intersexe. Le dévoilement intersexe repousse tout particulièrement les frontières de l’intime, puisqu’il renvoie à la corporéité sexuée de la personne qui l’effectue. Est-il compatible avec les critères de scientificité et ses normes de détachement? Je souligne les risques sociaux que comportent l’effacement identitaire systématisé, de même que l’importance d’inclure la réflexivité et le sensible pour respecter la rigueur intellectuelle.

    In a high flux pile the presence of local absorbers makes the power difficult to measure. In any case thermodynamic measurements are sometimes not very accurate. Another possible method could be the measurement of the cooling fluid activity. This has been tried on the heavy water circuit of EL3. In the first part of this report we give some qualitative indications of the various activities present in the heavy water in circulation. After this, the activity of the element chosen has been calculated. Finally, the results obtained from EL3 are given. (author) [French] Dans une pile a haut flux, la presence d'absorbeurs localises rend la mesure de la puissance difficile. Les mesures thermodynamiques sont par ailleurs parfois peu precises.

    Directory of Open Access Journals (Sweden)

    MACAN T. T.

    1976-01-01

    Full Text Available MINSHALL et KUEHNE ont signalé que, dans la « Région des lacs » en Angleterre, alors que la faune typique d'un ruisseau à fond pierreux peut monter jusqu'aux sources dans les montagnes, il y a des zones où la faune est pauvre, hormis les Plécoptères. Dans ces dernières eaux, le pH et le taux en calcium sont faibles, comme l'ont montré SUTCLIFFE et CARRICK qui pensent qu'il s'agit d'une pollution atmosphérique. De telles communautés habitent les affluents de la Rivière Lune. La rivière elle-même traverse une gorge où, grâce aux éboulis, le fond est stable. La faune actuelle est riche en espèces et en individus, surtout en larves de Tricoptères avec filet. C'est presque la seule région où les mollusques ne risquent pas d'être écrasés par les pierres roulantes. En aval, dans une longue plaine alluviale, le substrat est instable et, en conséquence, les espèces sont peu nombreuses bien que les individus de quelques-unes soient abondants. Une augmentation de l'enrichissement actuel provenant des villes et des prairies cultivées pourrait provoquer une croissance excessive des algues filamenteuses. Celles-ci font disparaître la vraie faune lithicole et disparaissent elles-mêmes en temps de crue, en emportant vers l'aval les animaux qu'elles hébergent. Au-delà de la plaine, la rivière traverse une région à pierre meulière, sur un lit plat et lisse. Entre deux barrages, ce lit est couvert de mousses habitées par 4 espèces d'éphémères qui ne se trouvent ailleurs, que dans de petites baies où le courant est faible. On a remarqué dans une rivière voisine la disparition de telles espèces après l'amélioration du lit par les ingénieurs.

    1995-04-01

    This report surveys cognitive aspects of color in terms of behavioral, neuropsychological, and neurophysiological data. Color is usually defined as psychophysical color or as perceived color. Behavioral data on categorical color perception, absolute judgement of colors, color coding, visual search, and visual awareness refer to the more cognitive aspects of color. These are of major importance in visual synthesis and spatial organization, as already shown by the Gestalt psychologists. Neuropsychological and neurophysiological findings provide evidence for an interrelation between cognitive color and spatial organization. Color also enhances planning strategies, as has been shown by studies on color and eye movements. Memory colors and the color- language connections in the brain also belong among the cognitive aspects of color.

    The passage of fission fragments is manifested in insulators by the formation of damage lines which can easily be observed by transparence using the electron microscope after a suitable chemical attack. Since the recording efficiency is 100 per cent for mica and plastics this phenomenon has a certain number of applications. After briefly recalling the interaction processes between charged particles and matter, and giving a quantitative study of the relationships connecting the various parameters, the author considers here some of these applications: - thermal neutron dosimetry: it is possible to measure integrated fluxes of between lO{sup 3} and 10{sup 21} n/cm{sup 2}, according to the method used; - fast neutron dosimetry: by using fission fragment threshold sources it is easy to measure biological type doses of about 1 rem: - dosage of very low fissile impurity concentrations: atomic concentrations of about 10{sup -9}; can be measured; this limit has never been attained by conventional methods; - study of fissile elements occurring in atmospheric dusts. Results are then briefly given of an automated counting test for traces effected by measuring the electrical resistivity, of the irradiated membrane. Finally are given the advantages and disadvantages of these solid detectors, especially with respect to nuclear emulsions whose uses are approximately identical.

    Full Text Available Les Touaregs utilisent des alphabets dont les caractères sont appelés tafineq, mot où l’on trouve une racine FNQ que certains auteurs ont rapprochée, à tort ou à raison, du terme dont les Grecs désignaient les Phéniciens. Ces alphabets dérivent d’alphabets beaucoup plus anciens, qu’on a pris l’habitude de qualifier de « libyques » ou « libyco-berbères ». On trouve des inscriptions « libyques » dans tout le Maghreb, depuis la Libye jusqu’au Maroc et même jusqu’aux îles Canaries, parfois associées à des inscriptions puniques ou latines. La découverte à Dougga (Tunisie de deux bilingues puniques-libyques dont la rédaction remonte au iie siècle avant J.-C. a permis le déchiffrement partiel de l’une des variantes de l’alphabet libyque. Des inscriptions marocaines sont probablement plus anciennes, mais les datations proposées sont sujettes à caution. En même temps qu’il rend compte de deux ouvrages récents, consacrés pour l’un à des inscriptions rupestres contemporaines et pour l’autre à l’évolution des écritures libyco-berbères de l’Antiquité jusqu’à nos jours, le présent article discute quelques-unes de ces hypothèses de datation, et évoque les circonstances de la première découverte des inscriptions de Dougga.The Tuareg use alphabets with characters called tafineq (plural: tifinagh. Some writers have, rightly or wrongly, related this word’s root (FNQ to the word used by the Greeks to refer to the Phoenicians. These alphabets derived from much older ones, which are usually said to be “Libyan” or “Libyco-Berber”. Libyco-Berber inscriptions are found throughout a region stretching from Libya to Morocco and even the Canary Islands — sometimes along with Punic or Latin engravings. Owing to the discovery in Dougga (Tunisia of two bilingual Libyco-Punic inscriptions dating from the 2nd century BC, one of the variants of the Libyco-Berber alphabet has been partly

    Full Text Available Previous studies concerned with neuropsychological aspect of delusions, were mainly focused on specific forms of this disorder. Comparatively small number of investigations were concerned with cognitive deficiencies accompanying the delusions. The substance of this study includes the detection of neuropsychological disfunctions in patients with persistent delusion disorder, and in tracing of these cognitive distortions to appropriate brain regions. Besides, characteristics of attribution style in these patients are analysed, from the aspect of their connections with unadjusted localized input for their reasoning system. The investigation is designed as a comparative study. The sample includes: a group of patients with persistent delusion disorder; a group of patients with paranoid schizophrenia; a group of healthy individuals. The participants have been tested by a neuropsychological battery that represents the following cognitive functions: attention, memory, vizuospatial and vizuoconstruction organization, executive ability, verbal divergent thinking. Projective Rorschach's method was used for estimation of attribution style.

    Leistedt, Samuel J

    2013-05-10

    Behavioural and social sciences are useful in collecting and analysing intelligence data, understanding terrorism, and developing strategies to combat terrorism. This article aims to examine the psychopathological concepts of terrorism and discusses the developing roles for behavioural scientists. A systematic review was conducted of studies investigating behavioural aspects of terrorism. These studies were identified by a systematic search of databases, textbooks, and a supplementary manual search of references. Several fundamental concepts were identified that continue to influence the motives and the majority of the behaviours of those who support or engage in this kind of specific violence. Regardless of the psychological aspects and new roles for psychiatrists, the behavioural sciences will continue to be called upon to assist in developing better methods to gather and analyse intelligence, to understand terrorism, and perhaps to stem the radicalisation process.

He describes the changes as "futuroshock", thus presenting a dilemma whether the changes are only a momentum or a pre-planned concept. He especially stresses the Toffler’s conclusion that turns a new page in futurology - examining the dangers that follow the changes. According to him, predictions are made with the help of practically all the sciences in two basic directions: explo...

  4. ETHICAL ASPECTS OF SUSTAINABILITY

    OpenAIRE

    Amantova-Salmane, Liene

    2015-01-01

    Ethics can be defined as a reflection on nature and a definition of “the good”. Individuals value qualities and things dissimilarly, most visibly, but they also value their goods in different ways, in different relations to each other, for different reasons, and to different ends. These differences are very applicable to sustainability. In other words, sustainability cannot be achieved without attention to its ethical dimensions. The aim of this research is to examine the ethical aspects of s...

    The electron spin resonance (E.S.R.) spectra of gamma irradiated polar organic glasses, at 77 K, shows a single line centered at g {approx} 2, attributed to solvated electrons. The radicals produced on scavenging this species by electron acceptors, such as aromatic hydrocarbons, nitro-compounds and azines have been studied by E.S.R. In most cases, the radicals from these solutes, the spectra of which are observed after elimination by warming of the radicals from the matrices, are produced by protonation of the anions formed by scavenging of electrons at 77 K. Thus, in the case of glassy solutions of nitro-compounds, the radicals R NO{sub 2}H are formed. They are characterized by a{sub N} = 15 G (nitrobenzene) or a{sub N} = 28 G (nitro-alkane). These radicals are also generated by U.V, photolysis at room temperature of solutions of nitro-compounds in alcohols and are shown to be the precursors of nitroxide radicals R - N - R (with N - O) observed simultaneously. Gamma irradiation of solutions of pyridine and of the three diazines, in alcohol glasses at 77 K, produces the radical formed by hydrogen addition to these compounds. The value of the coupling constant of the additional proton (7-10 G) indicates that it is bound to a nitrogen in the sp{sup 2} hydridation state. One has shown, taking pyridine as an example, that the addition to a carbon gives a much greater value of the coupling constant, of the order of 50-60 G. (author) [French] Les spectres de resonance paramagnetique electronique (R.P.E.) obtenus apres irradiation gamma, a 77 K, de verres organiques polaires tels que les alcools, comportent une bande unique centree a g {approx} 2, attribuable aux electrons solvates. On etudie par R.P.E. les radicaux provenant de leur capture par des solutes ayant une affinite electronique, en particulier les hydrocarbures aromatiques, les composes nitres et les azines. En general, les radicaux provenant de ces solutes, dont on observe les spectres apres elimination

    Methods allowing the visualization of acoustic images appear at the moment to be of great interest in the field of non-destructive testing as well as in that of underwater detection. In order to carry out certain calculations on the operation of an ultrasonic camera, it has been necessary to study the secondary electron emission of some piezoelectric materials liable to be incorporated into the equipment. The secondary electron emission of insulators is a rather complex phenomenon; in order to find a rational explanation for the observations made, a theory has been developed for the energy spectrum of the emitted electrons. The experimental results of this work have then been used to build an ultrasonic visualization installation. Some examples of acoustic images which have been visualized are also presented.

    The increase of bundle supply has become widespread in several sectors (for instance in telecommunications and energy fields). This paper review relates strategic aspects of bundling. The main purpose of this paper is to analyze profitability of bundling strategies according to the degree of competition and the characteristics of goods. Moreover, bundling can be used as price discrimination tool, screening device or entry barriers. In monopoly case bundling strategy is efficient to sort consumers in different categories in order to capture a maximum of surplus. However, when competition increases, the profitability on bundling strategies depends on correlation of consumers' reservations values. (author)

    The quality of a conventional radiographic image can be characterized in terms of five basic parameters; density, contrast, latitude, resolution and noise. Since xeroradiographic images exhibit very limited broad area contrasts, and image formation is predominantly due to edge enhancement, a straightforward description of image quality using the same five parameters is not adequate. A detailed study was made of the radiographic aspects of xeroradiography with special reference to mammography, and a summary of major findings to date with appropriate references to published papers is presented

    Perez, D.; Gomez, Y.

    2008-01-01

    In this section, the social aspects of Cuba's energy system are described, based on the accessibility and availability of energy services and the affordability and acceptance of these energy services by the population. Accessibility refers to the existence of modern energy services and supporting infrastructures that allow the population, regardless of income level, place of residence, race, religion, etc., the use of modern fuels. Logistics and the economy determine the amount and kinds of energy and energy services available in each place. Even if energy services are accessible to the population, problems with their availability during particular time periods may exist; thus, this section discusses the problems of availability of modern fuels in Cuba. Affordability relates to the ability of the population to pay for the energy services that are accessible and available. Energy prices should be low enough (without affecting the profitability of the producing companies) to enable everyone's minimum requirements for modern energy services to be satisfied. Acceptability concerns the social and/or environmental problems related to energy chains, ranging from production and use to the disposal of waste generated by energy production. Making an assessment of the acceptability of an energy option is often difficult and sometimes involves many issues, including social, environmental, cultural, economic and religious aspects at local and regional levels

    Adili, Fatemeh; Larijani, Bagher; Haghighatpanah, Mohammadreza

    2006-11-01

    This study was undertaken to consider the psychological aspect of diabetes with regard to improving clinical outcomes. The review was limited to literature reports on the causes, solutions, and treatments of some common psychological problems known to complicate diabetes management. A literature search was undertaken using Pub-Med, CINAHL, Proquest, Elsevier, Blackwell Synergy, Ovid, Ebsco, Rose net, and Google websites, including studies published in English journals between 1995 and 2006. Therefore about 88 articles were selected based on the inclusion criteria. In earlier studies, relatively little empirical research was found to substantiate the effect of psychological counseling in complicated diabetes. The greatest deficits were seen in areas of mental health, self-esteem parent impact, and family cohesion. There were some different factors, which influence the psychological aspect of diabetic patients, such as age, gender, place of living, familial and social support, motivation, energy, life satisfaction, and lifestyle. There are various types of solutions for coping with the psychological problems in diabetic clients. The most essential solution lies in educating the patients and healthcare providers on the subject. Before initiating each educational intervention, a thorough assessment would be crucial. Treatment plans may benefit from cognitive behavior therapy (CBT), behavior family therapy, improving family communication, problem-solving skills, and providing motivation for diabetic patients. Moreover, it seems that the close collaboration between diabetologists and psychologists would be fruitful.

    2017-09-01

    Full Text Available In the process of globalization of world economic processes, the role of individual national economies increases, comparative advantages of the development of a country are formed, and their competitiveness is ensured. That is why it is worth emphasizing the importance of increasing the competitiveness of each individual country, based on its internal capacity. In a broad aspect, the competitiveness of the national economy is perceived as the ability of the country to ensure the balance of its external proportions and to avoid those constraints imposed by the foreign economic sphere, to self-organizing the improvement of their world economic ties. The competitiveness of the economy at the macro level is associated with the duration of the cycle of reproduction of the main productive assets and, accordingly, the jobs, productive forces of society and determined by the overall economic efficiency of investment. The criteria of competitiveness of the national economy are the growth of social productivity of labor, increase of social and economic efficiency of production and standard of living of the population. The competitiveness of the national economy determines sustainable socio-economic development of the country, as well as sustainable development predetermines the competitiveness of not only the country, but also all its levels. Scientific results are obtained using special methods of research of economic objects and phenomena, that is, based on the correlation and regressive, comparative analysis (establishing the relationship between the indicator factor, as well as economic modeling. Findings. Generalizing analysis and the importance of the macroeconomic aspect of competitiveness were used in the research paper, which will allow to better respond to the economic situation, in accordance with the trends of the “green” transformation of the economy; which in turn will solve important problems of the development and implementation of its

On connait l'interet qu'il y a a garder dans un circuit de reacteur de l'eau de tres haute resistivite (plusieurs centaines a quelques millions {omega}.cm): abaissement de la corrosion, abaissement du taux de radiolyse, abaissement de la radioactivite des circuits et canalisations, les elements autres que les constituants de l'eau transportes par celle-ci devenant generalement radioactifs par leur passage au coeur du reacteur. Si la circulation d'eau se fait a des temperatures inferieures a 45 deg. C, les resines echangeuses d'ions organiques utilisees en lit melange resolvent tres bien le probleme de l'epuration en continu. Par contre, pour des temperatures plus elevees surtout au-dessus de 100 deg. C, leur utilisation n'est pas possible, la degradation de ces hauts polymeres etant tres rapide. De meme, l'action des rayonnements, par exemple ceux des produits fixes par les echangeurs d'ions, detruit irremediablement les chaines organiques constituant le squelette de ces echangeurs. Nous avons donc cherche d'es composes pouvant assurer une bonne deionisation de l'eau, mais de structures telles qu'elles ne soient pas deteriorees par l'action de la temperature et des rayonnements.

  8. Political and economic aspects

    International Nuclear Information System (INIS)

    O'Neil, C.

    1997-01-01

    The political and socio-economic aspects of oil and gas exploration in Canada's Arctic and the Beaufort Sea were reviewed. The federal government was very interested in developing the North because they saw oil and gas development in the North as a means of strengthening sovereignty claims. The projected profits from Northern oil and gas development were also very attractive, and after dealing with environmental and social concerns, the government granted the necessary drilling permits. The federal government also made allowances for huge tax incentives for the oil and gas companies to encourage exploration. Although oil has been found, large-scale production in the Beaufort Sea never materialized. During the period from 1984 to 1988, world prices for oil fell and it was no longer economical to undertake frontier production. Beaufort Sea operation were shut down as the oil industry changed its focus to more cost-effective reservoirs in southern Canada. 1 fig

    Diana-Maria Drigă

    2015-12-01

    Full Text Available The concept of resilience has represented during the recent years a leading concern both in Romania, within the European Union and worldwide. Specialists in economics, management, finance, legal sciences, political sciences, sociology, psychology, grant a particular interest to this concept. Multidisciplinary research of resilience has materialized throughout the time in multiple conceptualizations and theorizing, but without being a consensus between specialists in terms of content, specificity and scope. Through this paper it is intended to clarify the concept of resilience, achieving an exploration of the evolution of this concept in ecological, social and economic environment. At the same time, the paper presents aspects of feedback mechanisms and proposes a formalization of resilience using the logic and mathematical analysis.

    Full Text Available Customer loyalty - is a voluntary user solution for a long time to build relationships with the company. Loyalty is the user's desire for a long time to continue their relationship with a particular company, because loyal customers are those who purchase goods/services of the company from time to time. Loyalty can be treated as a customer desire, willingness to be a regular customer for a long time, buying and using the goods of the chosen companies by recommending them to friends and colleagues. Loyalty can be seen as a multi-dimension, covering behavioral and positional components, where positional aspect reflects customers' approach to business, while the behavioral dimension reveals a frequent and regular shopping, purchase quantity, size, range, availability, etc.

Thus, the present review aimed to survey the existing information about the culture, both on the world and the Brazilian scene. Issues related to botany, climate and soil requirements, alignment and planting density, cultivars, pests and diseases, among other technical aspects of this culture will be addressed. Pecan nut presents nutraceutical properties that are beneficial to human health, which has increased its demand from consumers. However, there are few research results with pecan nut in Brazil and there are many gaps in scientific knowledge about this culture, especially as regards the management of pests and diseases control, irrigation and nutrition, in Brazilian conditions.

    This viewgraph presentation provides information on Object Infrastructure Framework (OIF), an Aspect-Oriented Programming (AOP) system. The presentation begins with an introduction to the difficulties and requirements of distributed computing, including functional and non-functional requirements (ilities). The architecture of Distributed Object Technology includes stubs, proxies for implementation objects, and skeletons, proxies for client applications. The key OIF ideas (injecting behavior, annotated communications, thread contexts, and pragma) are discussed. OIF is an AOP mechanism; AOP is centered on: 1) Separate expression of crosscutting concerns; 2) Mechanisms to weave the separate expressions into a unified system. AOP is software engineering technology for separately expressing systematic properties while nevertheless producing running systems that embody these properties.

    Beside the technical problems of ADTT which remain to be solved it is crucial for the ADTT progress that safety and economical aspects are considered already during the research and planning phases. Safety here stands for the converse of risk, negative consequences for human life and health and the environment together with the corresponding probabilities. The system to be considered includes all phases of an ADTT plant, a life cycle analysis (LCA). The risk analysis is useful for two purposes: comparison with other ways of handling nuclear waste, e.g. geological repository and for valuation of different construction designs. Due to lack of precise plans and adequate data the analysis will be more of a qualitative than quantitative type. The main risks appear in connection with repair and replacement work. 2 refs., 1 fig

    The use of ionizing radiations is regulated in France in all fields of application. The main principles governing inspection activities in the food industry are outlined. Conventional preservation methods are mentioned, after which a discussion is devoted to the preservation of food products by irradiation treatment and the increasing importance given to this technique. Consumer protection automatically implies the obligatory use of dosimetry by inspection organisms if the irradiated merchandise is likely to serve for human or animal consumption. Irradiation treatment permits are granted in a context of specific statutory texts mentioned here. Supervision is constant, but always both realistic and flexible. Each aspect of this treatment is discussed in maximum detail if not quite exhaustively, with special emphasis on dosimetry as an indispensable safety factor [fr

    Full Text Available Burn injuries and their subsequent treatment cause one of the most excruciating forms of pain imaginable. The psychological aspects of burn injury have been researched in different parts of the world, producing different outcomes. Studies have shown that greater levels of acute pain are associated with negative long-term psychological effects such as acute stress disorder, depression, suicidal ideation, and post-traumatic stress disorder for as long as 2 years after the initial burn injury. The concept of allostatic load is presented as a potential explanation for the relationship between acute pain and subsequent psychological outcomes. A biopsychosocial model is also presented as a means of obtaining better inpatient pain management and helping to mediate this relationship.

    Full Text Available Infertility can be defined as a crisis with cultural, religious, and class related aspects, which coexists with medical, psychiatric, psychological, and social problems. Relation between psychiatric and psychological factors stem from a mutual interaction of both. Family is an important institution in maintaining human existence and raising individuals in line with society's expectations. Fertility and reproduction are seen as universal functions unique to women with raising children as the expected result of the family institution. Incidence of infertility has increased recently and can become a life crisis for a couple. Even though not being able to have a child affects both sexes emotionally, women feel greater amounts of stress, pressure, anxiety, and depression.Consequences of infertility arise from short and long-term devastating effects on both individual's physical and mental health, and marital system. Many studies focus on infertility related psychological and psychiatric disorders (depression, anxiety, grief, marital conflict, gender differences, relation between the causes of infertility and psychopathology, the effects of psychiatric evaluation and intervention -when necessaryon the course of infertility treatment, pregnancy rates, and childbirth. The most important underlying causes of high levels of stress and anxiety that infertile women experience are the loss of maternity, reproduction, sense of self, and genetic continuity. In this review article is to investigate the relationship between medically unexplained symptoms and psychiatric symptoms.

    2016-12-01

    Full Text Available Innovation in assisted reproductive technologies together with increased infertility and new family structures are increasing the use of gestational surrogacy as a means to have children. Before, during and after the process, it is necessary to study the psychosocial characteristics of triad members: the gestational surrogate, intended parents, and offspring. Research has indicated positive adaptation to the process and benefits for all members of the triad. Altruism is the main motivation of surrogates. Notably, psychological well-being has been found to be higher in individuals who have become parents through surrogacy than in those who have used egg donation or have followed a natural process of conception. Moreover, no differences in psychosocial characteristics have been observed in the offspring, compared with children born through natural conception or egg donation. Results highlight the positive aspects of surrogacy. Future research should investigate psychosocial factors that modulate the process, acting as risk and protective factors for well-being of the triad members, and identify the optimal profiles of surrogates for the process to be a success.

    Full Text Available The paper considers risk in the context of the main characteristics of non-classical epistemology. It states that non-classical epistemology is characterized by transformation, according to which the major priority of cognitive activity shifts the focus from the present to the past. In this situation a subject is keen not on what he or she has learnt but on what can be learnt. Truth being a crucial criterion of scientific knowledge is becoming of less priority, while risk is becoming more and more significant and acts as one of the major epistemology measurements. Risk is gaining the status of epistemological phenomenon, which shows a growing degree of uncertainty as a cognitive process background and the necessity for a subject to learn the world (make decisions under the conditions of uncertainty degree strengthening. The author states that risk is a comprehensive notion and it obtains a base value for all other aspects of its application, specifically, in the role of epistemological phenomenon.

    Precise computation of neutron flux in the core of a nuclear reactor represents one of the basic aspects of reactor design and operation. Neutron flux is computed by solving Boltzmann`s linear equation. Anyway, the direct solution of the equation involves too great a number of operations for practical application, leading up to TeraFlops or even PetaFlops supercomputing capabilities. Physical and mathematical models are then required to handle the extensive variety of configurations encountered. Numerical methods must be adapted to the rapid evolution of computer power, as also computer architecture: sequential, vector or parallel. Physical and mathematical models must allow for very fast estimation for online control and monitoring, adequate quantification for industrial studies and high-precision, best estimate computations. Coupling of neutronics to mechanics and two-phase flow thermohydraulics must be implemented in order to improve the accuracy in best-estimate computation schemes and to take into account the transient behaviour of the plant during normal operation or incidents. In this field of continuous improvement, the new methods applied in Reactor Physics lead obviously to good results and provide the improvements required in the future for the needs of efficiency, safety and advanced fuel cycle. This trend and the ``evolutionary`` implementation in large and modular software systems will be illustrated by the example of the SAPHYR system. (authors). 3 tabs.

    Full Text Available Reconstruction of the penis in transgender operations, amputation of the penis, congenital deformities and anomalies of the penis was and remains today an important issue in plastic surgery of the urogenital region. The only method to restore the penis is phalloplasty. In general, over the past decades, generations of clinicians have different ways and flaps for total fallouretheral reconstruction. Thus was formulated the characteristics of an ideal flap for the formation of neophallos, which should be safe, sensitive, without hair, and with long leg. However, despite the fact that the characteristics of a perfect flap, nowadays there is no “gold standard” in the formation of neophallos, as phalloplasty is a fairly complicated surgery, and the choice of method depends on many factors. The choice of methodology is determined by the plastics surgeon and to each patient is individual, depends on the etiology of the disease and the possibility of choosing the form of the donor’s transplant. This article presents a literature review devoted to the historical aspects of phalloplasty. In the article, in chronological order reflected the evolution of the different forming methods neofallos, phallourethrоplasty, describes their advantages and disadvantages.

    The economic magnitude of epilepsy is determined by its effect on the employment status of the patients, the cost of drug treatment for them and the healthcare system and the repercussion worldwide. Studies of the cost of the disease show that it has economic importance due to the sum of the direct and indirect costs caused by it. In the case of epilepsy, the results of studies in various countries led to the creation of a Commission on Economic Aspects of Epilepsy. The lack of epidemiological studies regarding epilepsy in Spain may explain the lack of publications on this subject in our country. The percentage of the total cost due to antiepileptic drugs is considerable and will probably increase in the future. The pharmaco-economic evaluation made by cost-benefit, cost-effectiveness, cost-usefulness analysis and studies to minimize costs should serve to use healthcare resources in the most effective manner and justify the rational use of the new antiepileptic drugs. The economic impact of epilepsy is added to the repercussion of the disease itself on the patient and his family. The different distribution of costs in children and adults with epilepsy suggest the need for intervention at an early age to try to reduce the long term economic and personal repercussions. The pharmaco-economic evaluation of the new antiepileptic drugs will make it clear whether their considerable cost is worth paying for their greater effectivity.

  6. Electrical aspects of rainout

    Rosenkilde, C.E.

    1981-01-01

    Rainout commonly denotes the aggregate of phenomena associated with precipitation scavenging of radioactivity from a cloud of nuclear debris that is within a natural rain cloud. (In contrast, the term, washout, is applicable when the nuclear cloud is below the rain cloud and the term, fallout, commonly denotes the direct gravitational settling of contaminated solid material from a nuclear cloud.) Nuclear debris aerosols may be scavenged within natural clouds by a variety of different physical processes which may involve diffusion, convection, impaction, nucleation, phoresis, turbulence, and/or electricity among others. Processes which involve electrical aspects are scrutinized for their susceptibility to the intimate presence of the radioactive-cloud environment. This particular choice of electrical processes is not accidental. Nearly all of the listed processes were examined earlier by Williams. His rough estimates suggested that electrical effects, and to a lesser extent turbulence, could enhance the scavenging of those submicron aerosols which reside in the size-range that bridges the minimum in the scavenging rate coefficient which is commonly called the Greenfield gap. This minimum in the scavenging-rate coefficient is created by the simultaneous reduction of scavenging via diffusion and the reduction of scavenging via inertial impaction. However, Williams omitted the specific influence of a radioactive environment. This report aims to remedy this omission

    Full Text Available Bien que les aspects hydrodynamiques soient d'une importance primordiale lors de la conception et du fonctionnement d'un réacteur gaz-liquide-solide à lit fixe arrosé, les méthodes de calcul prédictif proposées sont restées fort rudimentaires. La plupart des études portant sur ce sujet ont été menées dans des conditions quasi atmosphériques alors que les réacteurs industriels fonctionnent à des pressions élevées. C'est seulement récemment que quelques résultats expérimentaux ont été obtenus à des hautes pressions, et des corrélations ont été proposées dans ces conditions pour prédire la transition entre les régimes ruisselant et pulsé, la perte de pression et le taux de rétention de liquide. L'objectif de cet article est double. D'une part, une synthèse y est présentée ; elle fait état des connaissances acquises sur les divers aspects hydrodynamiques du réacteur triphasique à lit fixe, incluant les récents développements réalisés à hautes pressions. D'autre part, les modèles et les corrélations actuels de transitions de régimes, de la perte de pression et du taux de rétention de liquide sont soumis à une analyse critique en confrontant leurs prédictions à l'ensemble des données expérimentales obtenues pour un large intervalle de la pression de fonctionnement du réacteur. Des conclusions objectives ont pu être tirées concernant les aptitudes des corrélations et des modèles actuels à être utilisées pour les calculs de conception des réacteurs triphasiques à lit fixe industriels. Malheureusement, il apparaît qu'aucun modèle de transitions entre les régimes ruisselant et pulsé n'est satisfaisant. Seule la corrélation empirique de Larachi et al. (1993 s'avère être jusqu'à présent la méthode la plus précise pour prédire la position de la frontière entre les régimes ruisselant et pulsé dans un large domaine de la pression de fonctionnement.

  8. Cultural Aspects of Suicide

    Full Text Available Undefined cultural factors cannot be dismissed and significantly contribute to the worldwide incidence of death by suicide. Culture is an all embracing term and defines the relationship of an individual to his environment. This study seeks to investigate the effect of culture on suicide both regionally and internationally. Culture-bound syndrome with suicidal behaviours specific to a particular culture or geographical region are discussed. Opinions are divided as to the status of religious martyrs. The law itself is silent on many aspects of suicidal behaviour and despite decriminalization of suicide as self-murder, the latter remains on the statutes of many developing countries. The Caribbean region is of concern due to its steady rise in mean suicide rate, especially in Trinidad and Tobago where socio-cultural factors are instrumental in influencing suicidal behaviour. These include transgenerational cultural conflicts, psycho-social problems, media exposure, unemployment, social distress, religion and family structure. The methods used are attributed to accessibility and lethality. Ingestion of poisonous substances is most popular followed by hanging. The gender differences seen with regard to suicidality can also be attributed to gender related psychopathology and psychosocial differences in help-seeking behaviour. These are influenced by the cultural environment to which the individual is exposed. Culture provides coping strategies to individuals; as civilization advances many of these coping mechanisms are lost unclothing the genetic predisposition of vulnerable groups. In the management of suicidal behaviour, a system of therapeutic re-culturation is needed with an emphasis on relevant culture- based therapies.

    2014-06-01

    Full Text Available One of the most important conditions of the existence of every organization, every enterprise is to insure the long-term sustainable development, one of the conditions of which is the increase of an organizational competitiveness. In modern economic conditions, social aspects of competitiveness are now in the foreground of interest, because just the strategy of social responsibility (SSR of modern enterprises can assure some commercial benefits, in responding, at the same time, to the social demands and in creating its well-being. Such an approach is in the basis of the notion of competitiveness. Along with «rigid parameters», such as price characteristics, the capability to deal with competitors, effective financial and production policies, «flexible factors» of competitiveness are of a big importance: a personnel potential, individual and collective competencies, organizational and managerial capabilities. As a result, we have formulated a research hypothesis: the organizational competitiveness is defined by individual and collective competencies of an organization, is based on socially responsible actions, confirms the demand for the object and insures its sustainable long-term development. Any organization should base all its actions aimed to increase its competitiveness on its intellectual potential, or on the management of individual and collective competencies that assure the sustainable development and the goal achievement. For every organizational strategic action, an effective combination of these competencies exists. So, we suggest a new definition of competitiveness: it is a social and economic category of understanding of the social responsibility, having as a central element individual and collective competencies, based on socially responsible actions of an enterprise, insuring its long-term sustainable development.

    Directory of Open Access Journals (Sweden)

    2016-09-01

    Full Text Available The article considers language as the organization of the speech of any person in any situation, without which it is impossible to characterize the internal structure of the speech stream. Language is exactly a system of guidelines necessary for the activity in the social world. Communication is primarily nothing but as a way of making one or another correction in the image of the interlocutor’s world. In order for a language to serve as a means of communication, it must have a single or a similar understanding of reality behind it. Conversely, the unity of understanding the reality and the unity of coherence presuppose the possibility of adequate communication. A mandatory component of communication is the communicative act, that is, the act of sharing information between people. The speech, i.e. the natural sound language is an important means of conveying information that defines this aspect of the communication process as verbal communication. The idea of dialogue as the space, in which the exchange of information takes place, is defined as initial. Essentially, it is the dialogue that in this case acts as the backbone principle in dealing with problems of language. It is here that the essence of social and psychological transition to the analysis of communication is most visibly concentrated. An individual essentially "lives" in the world of Another person’s worlds, and studying the words of this person, he or she studies the "world" of Another person. Thus, the dialogue is not merely the interaction (verbal with another person, but, ultimately, the interaction with the world of culture.

    Although the psychological aspect of the rhinoplasty operation has been a subject of interest for a long time, with the exception of a few studies, sociological factors have been almost totally ignored. In this prospective study the personality characteristics and socioeconomic backgrounds of 216 rhinoplasty patients were evaluated. Between 1994 and 2000, a questionnaire and the Minnesota Multiphasic Personality Inventory (MMPI) were given preoperatively to 157 females and 59 males. The MMPI was also given to age-matched people as a control. Six months after surgery, patients were called on the telephone and asked to rate their satisfaction. According to questionnaire, a great majority of the rhinoplasty patients were young, unmarried women with high education levels. In the rhinoplasty group, one or more scales of the inventory were not in the normal ranges in 45% of the patients, whereas this proportion in the control group was 28% (p childish, highly active, impulsive, competitive, reactive, perfectionistic about themselves, talkative, and emotionally superficial. Male patients could be described as rigid, stubborn, over-sensitive, suspicious, perfectionistic, pessimistic, over-reactive, and having somatizations. Tension and anxiety with feelings of inferiority were found to be characteristics of the male patients. The satisfaction rate after six months was reported as 72%. There was no significant correlation between MMPI results and demographic variables, nor satisfaction rate. In conclusion, the rhinoplasty patients in our study are young people at the very beginning of their careers. It could be that their personalities and socioeconomic backgrounds combine to make aesthetic surgery rewarding enough, both socially and personally, to encourage them to follow through.

    The Large Aspect Ratio Tokamak Study (LARTS) at Oak Ridge National Laboratory (ORNL) investigated the potential for producing a viable longburn tokamak reactor by enhancing the volt-second capability of the ohmic heating transformer through the use of high aspect ratio designs. The plasma physics, engineering, and economic implications of high aspect ratio tokamaks were assessed in the context of extended burn operation. Using a one-dimensional transport code plasma startup and burn parameters were addressed. The pulsed electrical power requirements for the poloidal field system, which have a major impact on reactor economics, were minimized by optimizing the startup and shutdown portions of the tokamak cycle. A representative large aspect ratio tokamak with an aspect ratio of 8 was found to achieve a burn time of 3.5 h at capital cost only approx. 25% greater than that of a moderate aspect ratio design tokamak

    Full Text Available La taxis grecque – correspondant exact de l’ordo latin – est un aspect essentiel de la civilisation byzantine : elle organise cette société de manière à ce que celle-ci soit un reflet aussi exact que possible de la société céleste, décrite en particulier par Denys l’Aréopagite. La taxis est donc à la fois précise et contraignante et nous a été transmise dans des livres décrivant le protocole : le De Cerimoniis au Xe siècle, le Traité du pseudo-Kodinos au XIVe siècle. Au cours de cérémonies où tous les aspects matériels – l’habit, la couronne, le trône, les acclamations à la gloire de l’empereur, l’orgue qui les accompagne, les gestes accomplis par l’empereur comme par ceux qui l’entourent – ont un sens, l’Empire byzantin affirme ainsi son équilibre et sa qualité de peuple élu. Jusqu’en 1204, les autres nations ont jalousé la qualité que s’était octroyée l’Empire romain d’Orient : celle d’image de la cour céleste, qui est figurée dans le cérémonial. Cette jalousie a pris d’autres formes après 1453, et l’on s’intéressera aux souverains européens qui, tel Louis XIV, ont voulu faire figure d’héritiers de l’empire défunt et relever ses cérémonies.The Greek taxis(order– the exact equivalent of the Latin ordo – is an essential aspect of Byzantine civilization: it organized society in such a way that it would reflect the celestial society as closely as possible, as has been described by Dionysius the Areopagite.

    The principle of a differential calorimeter is briefly described. The apparatus allows a direct and continuous determination of the differential heat-capacity between a sample and a reference, in the range 20 to 600 deg. K approximately. Some examples concerning measurements at low temperatures of reversible or non reversible thermal effects are given. They show the possibilities of the apparatus and are connected with: - detection and measurements of thermal effects associated to structural transformations in elastomers at low temperatures, - measurements of Wigner energy released after neutron irradiations at 77 deg. K for: recrystallized pyro-graphites; high purity iron, aluminium. [French] On decrit brievement le principe d'un calorimetre differentiel qui permet la determination directe et continue de la difference de chaleur specifique apparente entre un echantillon et une reference, dans une gamme de temperatures s'etendant de 20 a 600 deg. K environ. On donne quelques exemples de mesure a basses temperatures d'effets thermiques reversibles ou non reversibles. Ils montrent les possibilites de l'appareillage et concernent: - la detection et la mesure d'effets thermiques associes a des transformations structurales dans des elastomeres a basse temperature, - la mesure du degagement d'energie Wigner apres des irradiations neutroniques a 77 deg.

    Bearing in mind the specific granular structure of sintered materials produced from powders, whose compaction process is linked with the sintering treatment, we have experimented with methods of checking the degree of sintering and certain other properties. The non-destructive methods used include: (1) Examination of the crystalline structure of solid sinters, using metallography and electron microscopy. These methods show the homogeneity of the structure, the grain size and orientation, the presence of various flaws such as inclusions and pores, and the actual course of the sintering process, including crystal formation, grain growth, etc. In certain cases the microscopic examination can be combined with micro-hardness tests. This examination of the microcrystalline structure is one of the principal methods of checking the quality of sintered materials, and is irreplaceable by any other method. (2) The degree of compaction, which is the main factor in determining the quality of sintered materials, can also be checked by measuring certain properties such as electrical and thermal conductivity in relation to density, since for sintered materials conductivity is directly proportional to the degree of sintering. We have also tested and found satisfactory a method for checking porosity, and have obtained interesting experimental data, especially on free porosity, which is susceptible to gaseous inclusions. The paper gives experimental data on the application of these methods to certain sintered materials of importance in nuclear technology.

    Introduction La production, la vente et la consommation des médicaments contrefaits sont de sérieux problèmes qui pèsent sur la Santé Publique particulièrement des pays en développement et pour lesquels il existe peu d'informations dans certains pays. Cette étude a été menée en vue de contribuer à la détermination de la prévalence des médicaments contrefaits, particulièrement celle des anti-infectieux consommés dans la ville de Lubumbashi en République Démocratique du Congo. Méthodes L’étude a visé des médicaments anti-infectieux administrés per os commercialisés dans la ville de Lubumbashi. L'inspection visuelle attentive de l'emballage, l'interprétation de l’étiquetage et l'observation attentive du produit ont servi de paramètres d’études. Les échantillons ont été acquis par achat auprès des fournisseurs licites et illicites. Résultats Cinq molécules: ampicilline, amoxycilline, ciprofloxacine, mebendazole et metronidazole ont été colletées. Sur 60 échantillons rassemblés: 31,7% se sont avérés contrefaits. L'ampicilline et le mebendazole sont les produits les plus contrefaits dans cette étude avec 26,3%, suivi de metronidazole avec 21,05%. 78,9% des médicaments contrefaits proviennent du secteur informel. La provenance de 47,4% d'anti-infectieux contrefaits est l'Inde, suivi de la Chine avec 26,3%. Conclusion Cette étude a montré la circulation des médicaments contrefaits dans la ville de Lubumbashi à un taux non négligeable. Une étude des caractéristiques physico-chimiques et de l'activité biologiques permettra d’évaluer l'impact de ces médicaments dans la prise en charge des infections. PMID:26977227

    From the checking of 2750 index cards of hazards, the study relates the distribution of the chemical hazards in the Centre d'Etudes Nucleaires of Fontenay-aux-Roses. Those concerning the greatest number of agents in the Centre are classified according to the categories corresponding to the different conditions of working. Thus, the most important are put forward. Then, the authors rapidly make a review of hazards which may have some special interest because they appear more specific of the nuclear energy or because they are the most frequently noted on the index cards of hazards. The case of the tributylphosphate is studied more precisely.

Les plus importantes d'entre elles sont ainsi mises en evidence. | Les auteurs passent ensuite en revue, rapidement, les nuisances qui peuvent presenter un interet particulier soit parce qu'elles semblent plus specifiques de l'Energie Nucleaire, soit parce qu'on les rencontre le plus frequemment sur les fiches de nuisances.

    Full Text Available Verb aspect, alternations and quantification In this paper we are briefly discuss the nature of Bulgarian verb aspect and argue that the verb aspect pairs are different lexical units with different (although related meaning, different argument structure (reflecting categories, explicitness and referential status of arguments and different sets of semantic and syntactic alternations. The verb prefixes resulting in perfective verbs derivation in some cases can be interpreted as lexical quantifiers as well. Thus the Bulgarian verb aspect is related (in different way both with the potential for the generation of alternations and with the prefixal lexical quantification. It is shown that the scope of the lexical quantification by means of verbal prefixes is the quantified verb phrase and the scope remains constant in all derived alternations. The paper concerns the basic issues of these complex problems, while the detailed description of the conditions satisfying particular alternation or particular lexical quantification are subject of a more detailed study.

    The Large Aspect Ratio Tokamak Study (LARTS) investigated the potential for producing a viable long burn tokamak reactor through enhanced volt-second capability of the ohmic heating transformer by employing high aspect ratio designs. The plasma physics, engineering, and economic implications of high aspect ratio tokamaks were accessed in the context of extended burn operation. Plasma startup and burn parameters were addressed using a one-dimensional transport code. The pulsed electrical power requirements for the poloidal field system, which have a major impact on reactor economics, were minimized by optimizing the field in the ohmic heating coil and the wave shape of the ohmic heating discharge. A high aspect ratio reference reactor was chosen and configured

    The nuclear controversy comprises many ethical aspects, e.g. the waste disposal problem. Nuclear opponents should not neglect the environmental protection aspect; for example, the use of nuclear power alone brought about an 8% reduction of the CO 2 burden in 1987. Our responsibility towards nature and humans in the Third World leaves us no alternative to nuclear power. On the other hand, the nuclear power debate should not become a matter of religious beliefs.

    I consider more specifically the cosmological aspects of supersymmetry breaking in ''superstring models'' (grand unified models which are believed to describe the effective theory obtained by compactification of superstring theories). The most interesting aspects are related to the presence of flat directions in the scalar potential (vacuum degeneracies). These flat directions are discussed both in the hidden sector of these models (do they give rise to inflation) and in the observable sector of quarks, leptons and Higgs particles, in connection with baryogenesis

    Full Text Available The reproductive cycle of the eared horse mussel, Modiolus auriculatus, was followed for one year from February, 2011 to January, 2012 based on 240 individuals collected from Hurghada, north coast of Red Sea, Egypt. The gonadal maturation of M. auriculatus was examined by means of macroscopic and histological preparations of the mantle. Annual cycle with periods of growth, maturity and discharge of gonadic products occurs simultaneously in both sexes. Ripe individuals were observed throughout the year. The largest number of spawning for the individuals occurred from March to June and July for the population. So, it was clear to identify one heavy spawning period for this species. Sexation of M. auriculatus did not differ significantly from 1:1. Sexes were distinguishable in all individuals at the ripe stage with a shell length greater than 3.00 cm. A direct positive correlation was observed between gonad index and water temperature.

    Magnetic structure determination of a few ferri- and antiferromagnets normal spinels has led us to study what are, besides nearest neighbour magnetic interactions, the magnetic terms which have to be considered in the establishment of such or such magnetic structure. Tetragonal distortion which is frequently observed in such compounds is of the order of magnetic exchange striction (10{sup -3}). Such a distortion leads to two effects. First it decreases the total energy of the system. Secondly it introduces term of axial magnetic anisotropy. Besides this term of axial anisotropy, the possibility of basal anisotropy in the case of coplanar magnetic structure has to be considered. This last term explained why the magnetic structures of such antiferromagnetic spinels frequently have one or more cell parameters which are twice that of the chemical cell. Finally the comparison between various magnetic structures of antiferromagnetic spinels in which the leading term is the magnetic energy between first nearest neighbours, shows that the part played by magnetic interactions between non nearest neighbours is not negligible. Such indirect superexchange interactions through two anions or two anions and a cation on tetrahedral site, although of the order of a few percent of the preceding one, join a given ion to its twelve second nearest neighbours, six third nearest neighbours and twelve fourth nearest neighbours. (author) [French] La determination des structures magnetiques de quelques spinelles ferri- et antiferromagnetiques normaux nous a conduit a preciser quels sont, en dehors du terme dominant d'interaction magnetique entre ions premiers voiins, les termes d'energie magnetique a considerer dans l'apparition de telle ou telle structure magnetique. La distorsion quadratique que l'on observe frequemment dans ces composes est de l'ordre de grandeur de celle attribuable a la striction d'echange (10{sup -3}). L'effet d'une telle distorsion est double. Non seulement elle

Ces microparticules se sont révélées très actives en combustion et ont montré que la concentration du métal n'était pas le seul facteur à prendre en considération mais que la manière dont il était combiné pouvait être prépondérante. Pour étendre le domaine d'application des modèles, d'autres paramètres comme les conditions de fonctionnement de la chaudière et l'atomisation du fuel ont été pris en compte en plus des paramètres d'influence propres au fuel (travaux du Laboratoire Énergie du MIT publications 1986.

Uranium and zirconium tetrafluoride are much more soluble in N{sub 2}O{sub 4}-HF mixtures than in pure hydrogen fluoride. Uranium dissolved in these mixtures is pentavalent.

    Full Text Available Le présent article est une présentation de Constantinople telle qu’elle apparaît dans quelques textes romanesques du XIXe siècle grec. À cette époque Constantinople/Istanbul est encore pour les Grecs la capitale naturelle de l’hellénisme. Le point commun de tous les textes romanesques grecs de cette période, c’est qu’ils soulignent la continuité entre l’Empire byzantin et l’Empire ottoman. Si l’élément grec de la population y est souvent surévalué — on n’y parle presque jamais des Turcs — sans être pour autant idéalisé, les quartiers grecs sont sales, certains auteurs, comme Constantin Ramfos, sont très sensibles à la beauté de l’architecture ottomane. C’est une Istanbul aujourd’hui disparue que ces textes rares et non traduits nous révèlent.The present article is a presentation of the city of Istanbul as it appears in 19th century texts, in Greek novels. At the time Constantinople/Istanbul still felt like the natural capital of Hellenism for Greeks. The point that all those texts have in common, in the particular period, is that they underline the continuity between the Byzantine Empire and the Ottoman Empire. Even if at some points the Greek element of the population is over evaluated – there is rare if ever any mention of Turks in those texts – it is never idealized. The Greek neighbourhoods are described as being dirty and certain authors, like Constantine Ramfos, appear to be very sensible to the beauty of the ottoman architecture. These rare and non translated texts reveal to our eyes the city of Istanbul as a city that has now disappeared.

    This work is a critical review of the existing work on ferrous chloride and presents, as well, a number of new experimental results. First, a careful analysis of the level structure of ferrous ions in the crystalline field shows that the crystalline anisotropy is of the same order of magnitude as the exchange interactions, a feature which gives rise to some particular effects, such as an upward curvature of the magnetization curve at 0 K in a perpendicular magnetic field. Further, the very low temperature (T > 0.4 K) thermal variation of both the specific heat and magnetic susceptibility evidences a magnetic component in elementary excitations. This result suggests the presence of a large magneto-elastic coupling. Finally, an experimental study of the H-T phase diagram near T{sub N} and of the critical behaviour of the specific heat and parallel susceptibility was performed. (author) [French] Ce travail constitue une analyse critique des resultats obtenus a ce jour sur le chlorure ferreux et comporte en outre quelques resultats experimentaux nouveaux.

D'autre part, la variation thermique a basse temperature (T > 0.4 K) de la chaleur specifique et de la susceptibilite magnetique montre la presence d'une composante magnetique dans les excitations de basse energie.

    of this type between two elements. We give the diagrams of uranium and sulphur as examples. The chemical properties of sulphur show that the dismutation phenomenon operates also in molten media reactions, thus emphasising the resemblance with aqueous solutions. Finally, we show briefly how it is possible to predict qualitatively the chemical properties of a given element in a molten solvent other than the LiCl-KCl eutectic. (author) [French] Le developpement de l'utilisation des milieux fondus notamment en chimie preparative et pour certaines applications technologiques, a pose le probleme de la connaissance des proprietes chimiques des elements dans ces solvants. Les etudes de structure des solutions fondues font etat de l'existence d'especes connues en solution aqueuse, telles que les ions et les complexes. Ce fait et d'autre part quelques travaux portant sur l'etude de reactions chimiques en milieu fondu, nous ont amene a etablir une comparaison entre ces milieux et les solutions aqueuses. Nous nous sommes proposes de montrer que l'on retrouve dans ces milieux les phenomenes fondamentaux de la chimie des solutions aqueuses, permettant de prevoir et d'interpreter les reactions. Les proprietes chimiques du vanadium, de l'uranium et du soufre dans l'eutectique LiCl-KCl fondu a 480 deg. C, nous ont servi d'exemple. Le premier probleme est l'identification des divers degres d'oxydation de ces elements existant dans le solvant choisi. Nous avons tente de le resoudre par la comparaison des spectres d'absorption obtenus en solution aqueuse et dans l'eutectique fondu. Nous discutons les possibilites de cette methode dans un chapitre consacre a la spectrophotometrie d'absorption dans l'eutectique LiCl-KCl. Au cours de l'etude des proprietes chimiques, nous insistons sur les moyens mis en oeuvre pour deplacer les equilibres: formation de complexes, variation des proprietes oxydo-reductrices avec la formation de complexes L'attention est plus particulierement portee sur les

    The Nuclear Engineering Department at Manchester University was established in 1959. Since that time post-graduate reactor physics studies have gradually enlarged and developed, starting virtually from scratch; experimental studies have concentrated on light-water systems and centred on the accelerator-driven, natural-uranium, light-water exponential. The paper contains a survey of the work to date, discussion of the results obtained, outlines of proposed future work, and, as they arise in the text, descriptions of various low-cost, labour-saving experimental techniques which have been adopted. The various divisions of the work are described below. The authors have studied neutron diffusion in light water using both pulsed source and steady source methods. In the former method they have particularly stressed full harmonic analysis to the extent of actually studying the higher modes as opposed to most former work which has tried only to eliminate them. In the study of steady source methods they have concentrated on eliminating all effects from finite source and detector size, resonance activation, flux perturbation and so on. The results of both are discussed and compared. A very careful measurement of absorption cross-sections by the pulsed technique, taking care to eliminate harmonic and other effects likely to lead to error is also in progress and is described. Thermal neutron spectra in ''poisoned'' light water are being measured as a means of investigating and developing integral detector techniques. This discussion includes some interesting time- and cost-saving examples. Large foil activation and counting techniques for measuring spatially averaged neutron densities, and hence a number of reactor parameters, have been studied. Some interesting points have arisen, particularly with regard to spectrum measurement. The method makes possible many reactor physics investigations with limited resources. A low-cost natural uranium, light-water exponential has been constructed. Its mechanical design gives considerable flexibility so that, for instance, measurements parallel and perpendicular to the fuel rods are greatly facilitated. A programme of steady-state measurements is under way. Future work is outlined, and includes fine structure measurements, voidage effects and pulsed neutron studies. (author) [French] Le Departement du genie nucleaire de l'Universite de Manchester a ete cree en 1959. Depuis lors, les etudes post-universitaires de physique des reacteurs se sont progressivement developpees et elargies en partant virtuellement de zero; les travaux ont porte sur les reseaux a eau ordinaire et notamment sur les experiences exponentielles a uranium naturel et a eau ordinaire alimentees par un accelerateur de particules. Les auteurs passent en revue les travaux effectues, etudient les resultats obtenus, donnent des apercus sur les recherches futures et illustrent leur expose par la description de diverses techniques experimentales adoptees a Manchester, qui sont peu onereuses et ne necessitent qu'un personnel reduit. Les principaux sujets de recherches sont decrits ci-apres. Les auteurs ont etudie la diffusion des neutrons dans l'eau ordinaire en employant successivement la methode de la source puisee et celle de la source stationnaire. Avec la premiere methode, ils se sont astreints a faire une analyse harmonique complete, au point d'etudier effectivement les modes superieurs alors que, par le passe, ont cherchait seulement a les eliminer. Au moyen de la methode de la source stationnaire, ils ont cherche surtout a eliminer tous les effets dus a la dimension de la source finie et du detecteur, al'activation par resonance, a la perturbation du flux, etc. Ils discutent et comparent les resultats de ces deux etudes. Le memoire decrit ensuite une mesure tres precise des sections efficaces d'absorption, egalement en cours, par la methode des neutrons puises, en prenant soin d'eliminer les effets harmoniques et autres, generateurs d'erreurs. Les auteurs mesurent les spectres de neutrons thermiques dans de l'eau ordinaire 'empoisonnee' afin d'etudier et de mettre au point des techniques de detecteurs integraux. L'expose de cette partie du programme contient certains exemples d'economies de temps et de ressources. Ils ont etudie les techniques d'activation et de comptage avec des feuilles de grande dimension pour la mesure des nombres volumiques moyens de neutrons, ainsi que plusieurs parametres de reacteurs. Certains points interessants sont apparus, notamment en ce qui concerne la mesure des spectres. Cette methode permet de proceder a de nombreuses recherches de physique des reacteurs avec des ressources limitees. On a construit a peu de frais un assemblage exponentiel a uranium naturel et a eau ordinaire. Sa conception mecanique lui donne une grande souplesse, si bien que, par exemple, les mesures paralleles et perpendiculaires aux barres de combustible en sont considerablement facilitees. Un programme de mesures a l'etat stationnaire est en cours. L'auteur donne un apercu des travaux futurs qui porteront notamment sur les mesures de structure fine, les effets cavitaires et les flux de neutrons puises. (author) [Spanish] El Departamento de Ingenieria Nuclear de la Universidad de Manchester fue creado en 1959. Desde entonces se han ampliado y desarrollado progresivamente los estudios superiores de fisica de reactores, empezando desde los cimientos; los experimentos se han concentrado en los conjuntos de agua ligera, en particular en conjuntos experimentales de agua ligera y uranio natural, alimentados por un acelerador. En la memoria se examina la labor efectuada hasta la fecha, los resultados obtenidos, las lineas generales de la labor futura, asi como las tecnicas experimentales adoptadas debido a su bajo costo y al hecho de requerir un personal escaso. A continuacion se describen las principales investigaciones realizadas. Los autores estudiaron la difusion neutronica en agua ligera utilizando fuentes pulsadas y fuentes de intensidad estacionaria. Las primeras se consagraron en particular al analisis completo de los armonicos, en especial los modos mas elevados, mientras que en las investigaciones anteriores se habia procurado unicamente eliminarlos. Con las segundas se trato de eliminar todos los efectos debidos a las dimensiones de la fuente finita y del detector, a la activacion por resonancia, a la perturbacion del flujo, etc. Los autores examinan y comparan los resultados obtenidos por ambos metodos. Describen igualmente mediciones muy cuidadosas, en curso de ejecucion, de la secciones eficaces de absorcion efectuadas por la tecnica de fuentes pulsadas, procurando eliminar los efectos armfiiicos y de otra Indole que pueden dar origen a errores. Para investigar y elaborar tecnicas de detectores integrales, han medido espectros de neutrones termicos en agua ligera 'envenenada' . Entre otras cosas, examinan algunos factores interesantes que permiten ahorrar tiempo y dinero. Han estudiado tambien las tecnicas de activacion de laminas de grandes dimensiones y las tecnicas de recuento para medir densidades neutronicas promediadas en el espacio, y tambien varios parametros del reactor. Han surgido ciertas cuestiones interesantes, en particular en lo relativo a las mediciones del espectro. Este metodo permite efectuar con recursos limitados numerosas investigaciones de fisica de los reactores. Los autores han construido un conjunto exponencial de uranio natural y agua ligera, de bajo costo. Gracias a sus caracteristicas mecanicas puede ser utilizado con muchos fines; por ejemplo, se facilitan considerablemente las mediciones paralelas y perpendiculares a las barras combustibles. Se encuentra en curso de ejecucion un programa de mediciones en estado estacionario. Los autores describen en sus lfneas generales la labor futura, que versara sobre todo en mediciones de la estructura fina, los efectos de cavitacion y estudios de flujos neutronicos pulsados.

    ésultante fait apparaître des rognons, des pentes qui s'évasent, des roches en équilibre, des inselbergs et des plaines de corrosion d'extension régionale. La migration des sels dissous des eaux souterraines crée des croûtes de compositions variées, qui constituent des paysages particuliers. (3) Les processus d'érosion des sols et des roches par les eaux souterraines comprennent les phénomènes suivants: la chenalisation, l'érosion par suintement, le sapement, qui tous sont des agents notables du recul des versants et d'érosion régressive vers l'amont. Les seuils et les limites sont importants dans de nombreuses actions chimiques et mécaniques des eaux souterraines. Une approche morphométrique quantitative des formes et des processus liés aux eaux souterraines est donnée en exemple à partir d'études choisies dans les terrains carbonatés et détritiques d'origine aussi bien ancienne que récente. Resumen Las aguas subterráneas tienen una importancia fundamental en la evolución de los paisajes geomorfológicos. En este artículo se consideran tres grandes categorías de procesos ligados al agua subterránea y sus correspondientes paisajes resultantes: (1) La disolución crea distintas geometrías kársticas, fundamentalmente en rocas carbonatadas, como respuesta a las condiciones de recarga, condicionantes geológicos, litologías y al propio flujo de agua subterránea. La velocidad de denudación y formación de cavernas se puede estimar a partir de los parámetros cinéticos e hidráulicos. (2) La erosión producida por las aguas subterráneas genera regolitas de alteración residual en los frentes de erosión, con los subsiguientes afloramientos de rocas inalteradas, inselbergs, rocas oscilantes o llanuras de corrosión de carácter regional. La recolocación de las sales disueltas crea costras superficiales de diferente composición.

    In this lecture, we present selected aspects of nuclear fusion. The importance of the initial geometry of the reaction and its relation to fusion barrier are first discussed. The effect of deformation leading to the notion of barrier distribution is then illustrated. After a brief overview of the advantages of macroscopic theories, the dynamics of nuclear system under large amplitude motion is reviewed. The di-nuclear concept is presented to understand the competition between fusion and quasi-fission. This concept is then generalized to account for the dissipative dynamics in multidimensional collective space. The last part of this lecture is devoted to new aspects encountered with radioactive beams specific properties of very extended neutron rich system, influence of pygmy or soft dipole resonances and charge exchange far from stability are discussed.

    Décrit la première fois par Virchow en 1860, le liposarcome est une tumeur mésenchymateuse rare. Cette rareté est relative car les liposarcomes représentent quand même 14 à 18% de l'ensemble des tumeurs malignes des parties molles et ils constituent le plus fréquent des sarcomes des parties molles. Pour la majorité des auteurs, il ne se développerait jamais sur un lipome ou une lipomatose préexistant. Nous rapportons un cas de volumineux liposarcome de la face dorsale du tronc. L'histoire de la maladie, l'aspect clinique inhabituel « de tumeur dans tumeur », l'aspect de la pièce opératoire nous fait évoquer la possibilité de la transformation maligne d'un lipome bénin préexistant.

    The first part of this paper discusses the fundamental properties of some simple chopper systems. The relations for burst duration, exit angle of the beam after the slit, and maximum deflection are given the results are presented in graphical form for convenience. In the second part velocity modulation as a mean of bunching the particles behind a slit-deflector system is investigated. Expressions for the minimum distance for bunching {psi}{sub 0}, bunching factor {gamma}{sub 0} and HF power are given for the case of single or multiple slit modulation. Beam acceleration following velocity modulation has also been investigated. Results are presented in graphical fashion. In the last part, the space charge effects on an ion pack during bunching is given. A simple differential equation expressing particle motion in axial and radial directions has been derived on the basis of certain approximations. Numerical integration of the equation has been carried out for a number of values of the parameters.

    With the development of the Internet and the WWW, information treatment has gained a new dimension. (Intelligent) software agents are one of the means expected to relieve human staff of the burden of information overload, and in the future to contribute to safeguards data acquisition, data evaluation and decision-making. An overview is given for the categories of Internet, intranet and desktop agents. Aspects of the potential application of agents are described in three fields: information access and delivery, collaboration and workflow management, adaptive interfaces and learning assistants. Routine application of agents is not yet in sight, but the scientific and technical progress seems to be encouraging. (author)

    Finally filling a gap in the literature for a text that also adopts the chemist's view of this hot topic, Professor Likhtenshtein, an experienced author and internationally renowned scientist, considers different physical and engineering aspects in solar energy conversion. From theory to real-life systems, he shows exactly which chemical reactions take place when converting light energy, providing an overview of the chemical perspective from fundamentals to molecular harvesting systems and solar cells. This essential guide will thus help researchers in academia and industry better understand solar energy conversion, and so ultimately help this promising, multibillion euro/dollar field to expand.

    Hauptbeschreibung Aspect-oriented-programming is a relatively new technique that has evolved on top of the already well-established approach of object-oriented programming. When it is used correctly, it promises to remove many redundant parts of a code that appear repeatedly in an application, essentially untangling the original code. Thus, it can lead to a cleaner, more separated software design, to greater modularity and maintainability. Time-savings in software engineering can also be huge cost-savings, and anything that increases software quality is a welcome sight in an industr

    1994-10-01

    The requirements of leadership in the current environment of health care reform necessitate a clear distinction between leadership and management, an alteration in traditional leadership roles, and an evaluation of the knowledge and skills needed to address the ethical issues that arise from such reform. Transformational leadership is well suited to the current climate in health care because of the manner in which it actively embraces and encourages innovation and change. The article explores the elements of transformational leadership, describes the need for transformational leaders to be cognizant of the ethical aspects of their roles, and outlines the responsibilities of transformational leaders as moral agents.

    Harman, R.

    1979-01-01

    The main fundamental aspects and problems of cathodic sputtering used mainly for thin film deposition and sputter etching are discussed. Among many types of known sputtering techniques the radiofrequency /RF/ diode sputtering is the most universal one and is used for deposition of metals, alloys, metallic compounds, semiconductors and insulators. It seems that nowadays the largest number of working sputtering systems is of diode type. Sometimes also the dc or rf triode sputtering systems are used. The problems in these processes are practically equivalent and comparable with the problems in the diode method and therefore our discussion will be, in most cases applicable for both, the diode and triode methods

    Full Text Available SUMMARY This literature review analyzed the evidence on nutritional aspects related to the pathogenesis and progression of endometriosis. Diets deficient in nutrients result in changes in lipid metabolism, oxidative stress and promote epigenetic abnormalities, that may be involved in the genesis and progression of the disease. Foods rich in omega 3 with anti-inflammatory effects, supplementation with Nacetylcysteine, vitamin D and resveratrol, in addition to the increased consumption of fruits, vegetables (preferably organic and whole grains exert a protective effect, reducing the risk of development and possible regression of disease. Dietary re-education seems to be a promising tool in the prevention and treatment of endometriosis.

    Full Text Available The trusts have been frequently used in the countries which function under the Anglo-Saxon law system, but it most certainly represents an innovation in the new Romanian legislation. For this reason, in this paper, we tried to highlight the main differences between the trust regulated in the Romanian Civil code and its corespondent in other legal systems. Observing that the trust in an institution that is mainly theoretical, and the reluctance of practicioners in using it, we tried to analyze the trust, regarding its practical side. In this paper, we will take into consideration the following aspects: the rights that the trustee acquires after establishing the trust, that will be explained through the new regulations regarding the division of assets, the quality of the parties and the limits in which the trustee may be held liable. Other important aspects are: the means that the new regulations provide in order to protect the interests of the creditors and at the same time, the fiduciary assets; the formalities which the law requires and the means of termination of the contract. In the end, in order to identify alternative solutions, we will compare the trust (regulated in the Civil code with the management of assets that belong to a third party.

    1987-01-01

    The author briefly discusses two new phenomena of recent interest, the 5/sup th/ force and variant axions. The former, for its elucidation, will require further gravitational experiments, but the author concludes that variant axions are now definitely rules out experimentally. Various aspects of superstring phenomenology are then addressed, including some of the generic predictions of superstrings and some of its generic problems. In particular, he discusses some of the phenomenological consequences of having an extra Z 0 boson and the circumstances under which this excitation is a genuine prediction of superstrings. Since it is likely that a more reliable relic of superstrings will be provided by the presence of superpartners at low energy (≤ TeV), he discusses some of the bounds for squarks and gluinos obtained at the SppS collider and the expectations for their production at the Tevatron. As a final topic, he touches upon some of the consequences that result from having the Fermi scale arise from an underlying theory. Some aspects of the composite Higgs model and of the strongly coupled standard model are briefly reviewed

  10. Nutritional Aspects of Dysphagia Management.

    Science.gov (United States)

    Gallegos, C; Brito-de la Fuente, E; Clavé, P; Costa, A; Assegehegn, G

    This chapter describes the nutritional aspects of dysphagia management by starting with the definition of these two conditions (dysphagia and malnutrition) that share three main clinical characteristics: (a) their prevalence is very high, (b) they can lead to severe complications, and (c) they are frequently underrecognized and neglected conditions. From an anatomical standpoint, dysphagia can result from oropharyngeal and/or esophageal causes; from a pathophysiological perspective, dysphagia can be caused by organic or structural diseases (either benign or malignant) or diseases causing impaired physiology (mainly motility and/or perception disorders). This chapter gathers up-to-date information on the screening and diagnosis of oropharyngeal dysphagia, the consequences of dysphagia (aspiration pneumonia, malnutrition, and dehydration), and on the nutritional management of dysphagic patients. Concerning this last topic, this chapter reviews the rheological aspects of swallowing and dysphagia (including shear and elongational flows) and its influence on the characteristics of the enteral nutrition for dysphagia management (solid/semisolid foods and thickened liquids; ready-to-use oral nutritional supplements and thickening powders), with special focus on the real characteristics of the bolus after mixing with human saliva. © 2017 Elsevier Inc.

    2012-11-01

    In the UK schools are required by law to protect students from bullying; the responsibility of teachers to govern such behaviour has been extended outside the school setting to include cyberbullying. In this investigation, cyberbullying in secondary education is explored from the student perspective using a qualitative method of enquiry. Reported awareness and understanding about the legal aspects of cyberbullying are investigated; consideration is given to legislation, cybercrime, children's rights, school sanctions and safeguarding responsibilities. A total of 197 male and female students aged between 11 and 14 years old participated. Despite the availability of information on guidelines and legislation at national, local, and school level, this does not appear to have reached ground level of the individual student. There is a considerable gap between what students should know and what they report to be aware of with regard to legal aspects of cyberbullying. To address concerns of keeping up with the pace of change in cyberbullying, a collaborative approach is required with young people and adults sharing expertise.

    The paper presents a review of the main thermophysical aspects of NPPs safety and efficiency increase applied to WWERs. Improvement of operating WWER units is the main short-term and medium-term tasks of the utilities in Ukraine. The new generation of reactors for increasing the reactor facilities efficiency should utilize achievements of thermo physics research results. The thermophysical aspects of NPPs safety and efficiency are envisaged in the context of the atomic energy development strategy. The analysis of thermophysical processes occurring in the core shows that a number of problems concerning boiling crisis and heat exchange intensification during transient and accidents are not solved in spite of numerous calculations and experimental research. The up-to-date safety conception includes severe accidents consideration for safety assessment. Review of severe accidents management is presented. Additional validation of the West advanced thermal hydraulic codes which are applied for WWERs reassessment calculations is required. Contribution of the processes which might occur in WWER containment to safety problems solving is considered as well. (author)

  13. Neurological aspects of lead intoxication

    Lehner, H

    1980-05-08

    This study gives a survey over the medical and scientific literature on lead intoxications, which were published until 1979. Neurologic aspects are of particular interest. At present dramatic cases of lead intoxications occur only rarely. However, there are numerous studies about cases of chronical, partly subclinical intoxications. This chronical type of lead intoxication can become manifest clinically as relatively vague symptoms, for example vertigos, insomnia, headaches and weakness. Contrary to this, serious encephalopathies, even with fatal outcome, and polyneuropathies with typical paresis of the radial nerve are preferably observed in acute lead intoxications. Besides the numerous sources of intoxication, also the different opinions found in literature are discussed, concerning the effects of lead on the human body. The fact that there are differing opinions about the limiting value of the blood-lead level at which intoxication symptoms have to be expected, becomes apparent when the determined blood-lead level values are compared and evaluated. Besides the description of general intoxication effects, the discussion of the neurologic aspects found in literature - not only those concerning the central, but also the peripheral system - are preferably concerned. Reports about neuropsychical alterations due to lead exposure, which are mainly found in children, supplement the numerous descriptions of the macroscopic and microscopic alterations of the nervous system provoked by lead. Finally the therapeutic and prophylactic measures given in the literature are discussed.

    2010-01-01

    In this chapter we discuss several of the most relevant subjects related to ethics on Rare Diseases. Some general aspects are discussed such as the socio-psychological problems that confront the patients and their families that finally lead to marginalization and exclusion of patients affected by these diseases from the health programs, even in wealthy countries. Then we address problems related to diagnosis and some ethical aspects of newborn screening, prenatal, pre-implantation diagnosis and reference centers, as well as some conditions that should be met by the persons and institutions performing such tasks. Alternatives of solutions for the most critical situations are proposed. Subsequently the orphan drugs subject is discussed not only from the availability point of view, prizes, industrial practices, and purchasing power in developed and developing societies. The research related to rare disease in children and other especially vulnerable conditions, the need for informed consent, review boards or ethics comities, confidentiality of the information, biobanks and pharmacogenetics are discussed.

    Full Text Available Throughout the paper, we have highlighted some controversial aspects regarding the crime of tax evasion, referring to some important decisions of the High Court of Cassation and Justice and also of the Bucharest Court of Appeal. Debating upon the impunity provision stated by art. 10 of Law no. 241/2005, the study also sheds light upon the issue of the perspective of the judicial organs regarding the juridical regime of the tax due for dividends. The main focus of the paper leads to the situations when there is legal ground for the tax due for dividends to be considered part of the damage caused by tax evasion crime. The study includes a short analysis of some relevant provisions of the Romanian Fiscal Code and also some aspects deriving from decisions issued by the Administrative and Tax Litigation Chamber of The High Court of Cassation and Justice concerning the legal regime of dividends. Consequently, the authors are presenting both perspectives of the interpretation of the issue regarding the tax due for dividends to be considered part of the damage caused by tax evasion crime, resulting from two decisions of the two Criminal Sections of The Bucharest Court of Appeal, also arguing in favour of the most solid interpretation among them

    Graça Cardoso

    2014-06-01

    Full Text Available Cancer is accompanied by important psychological distress experienced by both patient and family. From the moment of the diagnosis on, the patient has to develop a great number of mechanisms and tasks of adjustment to the illness and its circumstances. The high prevalence of anxiety and depressive disorders during the course of cancer increases in the end stage disea‐ se. Therefore, a global plan of intervention integrating somatic and psychological/ psychiatric care throughout all the phases of the illness is crucial in the treatment of these patients. Health professionals working on this field can also experience emotional reactions to their patients’ suffering. They should be aware of the emotional aspects involved and develop training to help them intervene adequately with the patient and the family. The articulation between oncologists, palliative care professionals, and mental health care teams can be of great help in providing good quality of care to cancer patients.

In this study, we examined some biological aspects of this species sampled in the Straits of Messina. The specimens were sexed, measured and weighed. The relationships between body measurements (length and width of the carapace, antennal length and length-weight relationship were calculated. Furthermore, the correlation matrix (Pearson’s coefficient was calculated. Two hundred specimens were collected, ranging in size from 81 to 305 mm in total length, and between 21 and 1490 g in weight. A rare juvenile of 39 mm CL was recorded. A sex ratio of 1:1 was found. The carapace length – weight relationship was almost isometric. The wide size range sampled and the presence of a juvenile, indicate an interesting habitat for studying the presence and growth of Scyllarides latus in the Straits of Messina.

    The authors highlight a few medical, biological and psycological aspects of the use of nuclear weapons, drawing attention to their viewpoint that doctors should actively participate in the fight against nuclear armament. The short and long-term radiation effects on man and ecology are presented based on the Hiroshima and Nagasaki experiences. The danger of human error within this framework is emphasised and it is suggested that it is the medical profession's duty to point out how the effect of stress and boredom can lead to a nuclear catastrophe. Medical expertise may also help in the identification of unstable personalities among those who have access to nuclear weapons and in the understanding of the psycology of international conflicts and the psychopathology of those leaders who would use nuclear war as an instrument of national policy. Finally the effects of the nuclear war threat on children and teenagers are considered. (C.F.)

    2018-05-01

    Nowadays, world development depends on the energy supply. The use of fossil fuels leads to two threats: depletion of resources within a single century and climate changes caused by the emission of CO2 from fossil fuels combustion. Widespread application of renewable energy sources, in which biofuels play a major role, is proposed as a counter-measure. The paper made an attempt to evaluate to what extent biofuels meet the criteria of sustainable development. It was shown that excessive development of biofuels may threaten the sustainable development paradigms both in the aspect of: intergenerational equity, leading to an increase of food prices, as well as intergenerational equity, resulting in degradation of the environment. The paper presents the possibility of sustainable biofuels production increase.

    Objective: the present study is aimed at showing the different characteristics of pharyngoceles in imaging exams (video fluoroscopic swallowing exam [VFSE] and computed tomography) and its correlation with clinical presentation. Material and method: pharyngocele cases were selected in imaging exams (video fluoroscopic swallowing exam [VFSE] and computed tomography) realized in our service, realizing clinical presentation correlation. Results: pharyngocele presents frequently with small dimensions and narrow orifice. When the size enlarges, clinical presentation is more evident and diverse, which can confuse with other cervical lesions that enlarge with Valsalva maneuver. Differential diagnosis can be done by imaging evaluation. Conclusion: we intended to demonstrate that many times pharyngocele can be presented with different aspects, not always being easy to recognize by clinics or imaging exams, but its diagnosis must be always remembered in our daily practice.

  5. Immune Aspects of Female Infertility

    Directory of Open Access Journals (Sweden)

    Andrea Brazdova

    2016-05-01

    Full Text Available Immune infertility, in terms of reproductive failure, has become a serious health issue involving approximately 1 out of 5 couples at reproductive age. Semen that is defined as a complex fluid containing sperm, cellular vesicles and other cells and components, could sensitize the female genital tract. The immune rejection of male semen in the female reproductive tract is explained as the failure of natural tolerance leading to local and/or systemic immune response. Present active immune mechanism may induce high levels of anti-seminal/sperm antibodies. It has already been proven that iso-immunization is associated with infertility. Comprehensive studies with regards to the identification of antibody-targets and the determination of specific antibody class contribute to the development of effective immuno-therapy and, on the other hand, potential immuno-contraception, and then of course to complex patient diagnosis. This review summarizes the aspects of female immune infertility.

  6. Holistic aspects of quantum mechanics

    International Nuclear Information System (INIS)

    Pietschmann, H.

    1987-01-01

    Aspects of quantum mechanics irreconcilable with classical physics are outlined. Quantum mechanics started with a negative statement about reality, namely: it is impossible to determine momentum and position of a particle simultaneously. Meanwhile it has generated an impressive body of predictions which can be tested and have been confirmed by suitable experiments. As a consequence a naive, local, materialistic concept of reality must be abolished and a novel approach, the holistic is introduced. This is illustrated by some examples e.g. the Pauli exclusion principle for electrons, the electron capture decay of 135 La as a model of the wavefunction reduction, the Bohr radius of the atom, electron localisation in the atom. An example from the quantum field theory is the calculation of magnetic moments of electron and muon where a particle cannot be considered separately and all other particles must be taken into account.

  7. Biomechanical aspects of playing surfaces.

    Nigg, B M; Yeadon, M R

    1987-01-01

    The purpose of this paper is to discuss some biomechanical aspects of playing surfaces with special focus on (a) surface induced injuries, (b) methodologies used to assess surfaces and (c) findings from various sports. The paper concentrates primarily on questions related to load on the athlete's body. Data from epidemiological studies suggest strongly that the surface is an important factor in the aetiology of injuries. Injury frequencies are reported to be significantly different for different surfaces in several sports. The methodologies used to assess surfaces with respect to load or performance include material tests and tests using experimental subjects. There is only little correlation between the results of these two approaches. Material tests used in many standardized test procedures are not validated which suggests that one should exercise restraint in the interpretation of these results. Point elastic surfaces are widely studied while area elastic surfaces have received little attention to date. Questions of energy losses on sport surfaces have rarely been studied scientifically.

  8. Solid surfaces : some theoretical aspects

    Das, M.P.

    1978-01-01

    An appraisal of the current situation concerning some of the theoretical aspects of solid surfaces is presented. First of all the characterization of the surfaces that involves the surface geometry and atomic composition for both the clean and adsorbed surfaces is discussed. Under this, the methods for determining the surface structure (such as low energy electron diffraction, field electron and field ion microscopy, photo emission spectroscopy and atomic scattering) and methods for determining the surface composition by the Auger electron spectroscopy are outlined. In the second part, emphasis is on the electronic structure of the clean and adsorbed surfaces. The measurements of ultra-violet and X-ray photo electron spectra are shown to yield the information about the surface electronic structure. In this context the many body effects such as, shake-up and relaxation energy etc. are discussed. Finally the status of the theory in relation to the experiments on angular resolved and polarization dependent photo emission are presented. (auth.)

    1982-02-01

    The purpose of this paper is to present a brief description of fuel reprocessing and some present developments which show the reliability of nuclear energy as a long-term supply. The following topics are discussed: technical reasons for reprocessing; economic reasons for reprocessing; past experience; justification for advanced reprocessing R and D; technical aspects of current reprocessing development. The present developments are mainly directed at the reprocessing of breeder reactor fuels but there are also many applications to light-water reactor fuel reprocessing. These new developments involve totally remote operation, and maintenance. To demonstrate this advanced reprocessing concept, pilot-scale demonstration facilities are planned with commercial application occurring sometime after the year 2000

    The authors highlight a few medical, biological and psycological aspects of the use of nuclear weapons, drawing attention to their viewpoint that doctors should actively participate in the fight against nuclear armament. The short and long-term radiation effects on man and ecology are presented based on the Hiroshima and Nagasaki experiences. The danger of human error within this framework is emphasised and it is suggested that it is the medical profession's duty to point out how the effect of stress and boredom can lead to a nuclear catastrophe. Medical expertise may also help in the identification of unstable personalities among those who have access to nuclear weapons and in the understanding of the psycology of international conflicts and the psychopathology of those leaders who would use nuclear war as an instrument of national policy. Finally the effects of the nuclear war threat on children and teenagers are considered.

    The paper presents the aspects of international GHG (greenhouse gases) emission trading, such as: quality of GHG emission data, possible partners, monitoring activity, market mechanisms and difficulties. The following conclusions are drown: - debates on international trade with GHG emissions are currently in a very early stage; - actions are possible and feasible, particularly after Kyoto Conference, as versatile mechanism (besides the Joint Implementation Projects) which have in view the lowering of the global emission costs in different zones of the planet; - difficulties concerning monitoring, reporting and verification, practically preclude implementing a system of emission trading covering all the GHG, all the sources and reservoirs; - an international viable system of emission trading could initiate with a limited number of participants and consideration of only emission categories easy to be confined and surveyed; - existence of a national market and corresponding institutions for monitoring which could booster an international system development

    Full Text Available We raise several elementary questions pertaining to various aspects of means. These questions refer to both known and newly introduced families of means, and include questions of characterizations of certain families, relations among certain families, comparability among the members of certain families, and concordance of certain sequences of means. They also include questions about internality tests for certain mean-looking functions and about certain triangle centers viewed as means of the vertices. The questions are accessible to people with no background in means, and it is also expected that these people can seriously investigate, and contribute to the solutions of, these problems. The solutions are expected to require no more than simple tools from analysis, algebra, functional equations, and geometry.

  16. Legal aspects of nuclear energy

    International Nuclear Information System (INIS)

    Kraut, A.

    1981-01-01

    The legal basis for the use of nuclear energy is generally given by an Atomic Energy Act. Additionally, however, a system of regulations and standards has to be set up to lay down more detailed requirements. The fundamental philosophy and strategy has to be specified by governmental organizations. For the specification and implementation of the requirements some minimum organizational arrangements are necessary, which are not only restricted to governmental organizations. Furthermore procedural regulations have to be laid down before the implementation phase. This includes aspects like public participation in the licensing procedure. In practice, however, the implementation of the legal requirements always shows some weakness of the basic legal requirements. To learn from this experience some examples are presented, which gave rise to difficulties in the implementation procedure. (orig./RW)

    Diagnostic errors can result in tangible harm to patients. Despite our advances in medicine, the mental processes required to make a diagnosis exhibits shortcomings, causing diagnostic errors. Cognitive factors are found to be an important cause of diagnostic errors. With new understanding from psychology and social sciences, clinical medicine is now beginning to appreciate that our clinical reasoning can take the form of analytical reasoning or heuristics. Different factors like cognitive biases and affective influences can also impel unwary clinicians to make diagnostic errors. Various strategies have been proposed to reduce the effect of cognitive biases and affective influences when clinicians make diagnoses; however evidence for the efficacy of these methods is still sparse. This paper aims to introduce the reader to the cognitive aspect of diagnostic errors, in the hope that clinicians can use this knowledge to improve diagnostic accuracy and patient outcomes.

  18. Geological aspects of acid deposition

    International Nuclear Information System (INIS)

    Bricker, O.P.

    1984-01-01

    The general pattern of rain falling on the earth and reacting with the materials of the lithosphere (the weathering reactions so familiar to every beginning geology student) began soon after the earth was formed and has continued to the present. Anthropogenic additions to the natural acidic components of the atmosphere have increased since the time of the industrial revolution until they now rival or exceed those of the natural system. The severity of the environmental perturbations caused by these anthropogenic additions to the atmosphere has become a hotly debated topic in scientific forums and in the political arena. The six chapters in this book address various aspects of the acid deposition phenomenon from a geological perspective. It is hoped that the geological approach will be useful in bringing the problem more clearly into focus and may shed light on the geochemical processes that modify the chemical composition of acid deposition after it encounters and reacts with the materials of the lithosphere

    To review recent literature around the controversial diagnosis of personality disorder, and to assess the ethical aspects of its status as a medical disorder. The diagnostic currency of personality disorder as a psychiatric/medical disorder has a longstanding history of ethical and social challenges through critiques of the medicalization of deviance. More recently controversies by reflexive physicians around the inclusion of the category in the forthcoming revisions of International Classification of Diseases and Diagnostic and Statistical Manual of Mental Disorders classifications reflect the problems of value-laden criteria, with the diagnostic category being severely challenged from within psychiatry as well as from without. The clinical diagnostic criteria for extremely value-laden psychiatric conditions such as personality disorder need to be analyzed through the lens of values-based medicine, as well as through clinical evidence, as the propensity for political and sociolegal appropriation of the categories can render their clinical and diagnostic value meaningless.

    This U.S. contribution to the syllabus for Subgroup 5C treats with environmental and ecological aspects specific to fast breeder reactors, physical protection and safeguarding of the FBR cycle, fuel cycle centers (site selection problems for different degrees of collocation) and administrative and legal problems. Decommissioning of an FBR power plant, syllabus item C.1.7, is treated in separate contribution, more information on advanced safeguards for the fast breeder fyel cycle is contained in the contribution, USA WG 5C-tbd. A key conclusion of this is that with safeguards planning initiated early in the development of the FBR fuel cycle, time is available to develop, evaluate, and implement improved safeguards techniques and incorporate them into the design phase of all FBR cycle facilities

    1975-01-01

    A scintillation counter, particularly for counting gamma ray photons, includes a massive lead radiation shield surrounding a sample-receiving zone. The shield is disassembleable into a plurality of segments to allow facile installation and removal of a photomultiplier tube assembly, the segments being so constructed as to prevent straight-line access of external radiation through the shield into radiation-responsive areas. Provisions are made for accurately aligning the photomultiplier tube with respect to one or more sample-transmitting bores extending through the shield to the sample receiving zone. A sample elevator, used in transporting samples into the zone, is designed to provide a maximum gamma-receiving aspect to maximize the gamma detecting efficiency. (U.S.)

    1973-01-01

    General health aspects of carbon monoxide, lead, nitrogen oxides, unburned hydrocarbons, and aldehydes are described. Unlike spark ignition engines, diesel engines emit but minimal quantities of carbon monoxide. Automotive carbon monoxide may cause chronic poisoning by its combination with hemoglobin. The threshold value beyond which physiological changes occur lies at 2.5 percent carboxyhemoglobin. Nitric oxide, and especially nitrogen dioxide cause pulmonary edema, impaired respiratory function, and chronic bronchitis in very low concentrations. According to regulations implemented in France, a CO concentration of 40 ppM/hr must occur not more than 1 percent of the time on a yearly basis. A level of 15 ppm must not be exceeded for more than 15 percent of the time in any 9-hour period. The maximum allowable 1-hour nitrogen oxide concentration is set at 0.25 ppM. The emission standards implemented, as well as favorable meteorological conditions have resulted in an abatement of the CO concentrations in Paris.

    2007-11-01

    Due to increasing immigration in Germany the German Mental Health Care System today has to deal in a growing number with the assessment of the level of psychic functioning and the capability of self control in patients of different ethnic origin. For clinicians this is a challenge, since suicidal behaviour in terms of its frequency, meaning, motives and manner is very much dependent on the cultural context in which it occurs. Moreover, the general attitude of an individual towards suicide is embedded in the culture of origin of the immigrant. Until now there has been only little systematic research on the influence of culture on suicidal behaviour. In this review the traditions of suicidal behaviour in different cultures in their religious and historical dimensions will be reflected. The historical and cultural roots of suicidal behaviour will be put in context to a categorization of the different variants of suicide, such as institutionalized suicide versus individualized suicide. Psychodynamic aspects of suicidal ideation will be highlighted in cross-cultural perspective with a distinction between a. the wish to die, b. the wish to kill and c. the wish to be killed. It will be shown that there can be differentiated between accepted and non-accepted suicide. With respect to epidemiology there will be discussed the impact of culture on the suicide rates across cultures. The influence of culture on the psychopathology of suicidal behaviour will be summed up systematically. These aspects are of high relevance for the understanding and assessment of suicidal crisis in immigrants, since the suicidal patient even today - although subconsciously - is influenced by the deep rooted traditions of suicidal behaviour in his culture of origin.

  4. Psychosomatic aspects of Cushing's syndrome.

    2010-06-01

    There has been growing interest in the psychosocial aspects of Cushing's syndrome, such as the role of life stress as a pathogenetic factor, the association with affective disorders, and the presence of residual symptoms after treatment. Interestingly, a temporal relationship between stressful life events and disease onset is relevant only to pituitary-dependent Cushing's disease, and not to the pituitary-independent forms. A number of psychiatric and psychological disturbances may be associated with the active hypercortisolemic state, regardless of its etiology. Within the high frequency of mood disorders (about 60%), major depression is the most common complication. Other psychopathological aspects include mania, anxiety disorders, psychological symptoms (demoralization, irritable mood, somatization) and cognitive impairment. Cognitive symptoms are associated with brain abnormalities (mainly loss of brain volume). Quality of life may be seriously compromised during both active and post-treatment phases. Long-standing hypercortisolism may imply a degree of irreversibility of the pathological process. Recovery, thus, may be delayed and be influenced by highly individualized affective responses. Outcomes of Cushing's syndrome treatment are not fully satisfactory. Within its great complexity, a conceptual shift from a merely biomedical care to a psychosomatic consideration of the person and his/her quality of life appears to be necessary to improve effectiveness. It is time to translate the research evidence that has accumulated into clinical practice initiatives. To patients who show persistence or even worsening of psychological distress upon adequate endocrine treatment psychiatric/psychological interventions should be readily available. Applying interdisciplinary expertise and addressing the needs for rehabilitation would markedly improve final outcome.

    In this paper there are showed and debated some situation in which psychological effects like loss aversion, reference point, status-quo and framming effects can influence the deccision of the consumer and are not consistent with the standard economic model.In addition to this aspects, Cumulative Prspect Theory enhance the fact that decision makers overestimate low peobabilities and underestimate high probabilities,thus buying inadequate insurance in many situation.in thiss sense, in order to support this idea I tried to make a qualitative presentation of the model used on the insurance market using Prelec function which is the function related with the Cumulative Prospect Theory which can be used in the insurance context.The weak points of the theory of expected utility are explained through this new perspectives and nevertheless aspects like insensivity to bad news concerning incomes,elasticity of price,displacements of status-quo and default,disposition effect and equity premium are taken into consideration.As example,I chose a Kunreuther experiment about insurance decision in with is underlyined the fact that for moderate risk people buy insurance with premiums that exceed the expected loss.There are demands for low deductibles in the the markets for extended guarantees and insurances for mobile phones where was observed that the insurance underwriting rate increases with the probability of loss keeping the expected loss constant.It is better to mention that the theory and the model that are presented here comes as complementary to the economic standard theory not as a substitute.

  7. Une poétique du vœu : inspiration poétique et mystique impériale dans le poème XIX (et quelques autres d’Optatianus Porfyrius

    2010-11-01

    Full Text Available La majorité des poèmes d’Optatianus Porfyrius qui nous sont parvenus est dédiée à l’empereur Constantin et consacrée à son éloge. Mais dans cette poésie visuelle d’un nouveau genre, la célébration de l’art poétique tient une place aussi importante que la célébration impériale. Comment considérer le discours proprement poétique d’Optatianus ? Est-il simplement juxtaposé au discours politique ? Relève-t-il d’une pure convention ornementale ? Ces questions sont d’autant plus pertinentes que, loin de présenter le procédé visuel dont il est l’inventeur comme un art technicien, Optatianus revendique le double titre de poiètès et de uates et convoque les divinités de l’inspiration, Phébus et les Muses, alors même que ses poèmes se font l’écho de la nouvelle théologie chrétienne du pouvoir. La réponse apparaît double. D’une part, la poésie d’Optatianus peut être définie comme votive. Ses poèmes s’inscrivent dans la liturgie du pouvoir, c’est-à-dire dans le cadre d’une théologie impériale qui repose sur l’affirmation de l’éternité de la victoire et sur le renouvellement du charisme victorieux à travers le rituel des voeux. Par son discours sur Phébus et les Muses, Optatianus met en place une véritable poétique du voeu, qui consiste à couler la mystique de l’inspiration dans le moule de la mystique impériale. D’autre part, ce projet poétique répond à bien des égards à l’attente impériale. Il rencontre la volonté de Constantin de développer une politique culturelle, et se plie à quelques traits caractéristiques de sa religiosité : conviction de la nécessité du secours divin dans les actions humaines, d’une inspiration divine dont Constantin a fait lui-même l’expérience, attention aux signes et aux visions, attachement à un charisme solaire qui coexiste sous une forme « neutralisée » avec sa foi chrétienne.

    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.

  12. Computational aspects of premixing modelling

    Energy Technology Data Exchange (ETDEWEB)

    Fletcher, D.F. [Sydney Univ., NSW (Australia). Dept. of Chemical Engineering; Witt, P.J.

    1998-01-01

    In the steam explosion research field there is currently considerable effort being devoted to the modelling of premixing. Practically all models are based on the multiphase flow equations which treat the mixture as an interpenetrating continuum. Solution of these equations is non-trivial and a wide range of solution procedures are in use. This paper addresses some numerical aspects of this problem. In particular, we examine the effect of the differencing scheme for the convective terms and show that use of hybrid differencing can cause qualitatively wrong solutions in some situations. Calculations are performed for the Oxford tests, the BNL tests, a MAGICO test and to investigate various sensitivities of the solution. In addition, we show that use of a staggered grid can result in a significant error which leads to poor predictions of `melt` front motion. A correction is given which leads to excellent convergence to the analytic solution. Finally, we discuss the issues facing premixing model developers and highlight the fact that model validation is hampered more by the complexity of the process than by numerical issues. (author)

  13. Global aspects of gauge anomalies

    International Nuclear Information System (INIS)

    Zhang, H.

    1988-01-01

    This dissertation discusses the global aspects of gauge anomalies in even dimensions. After a very brief description of local gauge anomalies, the possible global gauge anomalies for various gauge theories are discussed using homotopy theory. One of the main results obtained in a general formula for the SU(n - k) global gauge anomaly coefficient in arbitrary 2n dimensions. The result is expressed in terms of the James number of the Stiefel manifold SU(n + 1)/SU(n - k) and the generalized Dynkin indices. From this, the possibilities of SU(n), SU(n - 1), and SU(2) global gauge anomalies in arbitrary 2n dimensions have been determined. We have also determined the possibilities of global gauge anomalies for the gauge groups SP(2N) and SO(N) in certain general dimensions, as well as for the exceptional gauge groups in specific dimensions. Moreover, several general propositions are formulated and proved which are very useful in the study of global gauge anomalies

  14. Environmental aspects of nuclear power

    International Nuclear Information System (INIS)

    Ward, D.P.

    1987-01-01

    Nuclear power provides the world with an important option for generating electricity. To successfully and safely utilize this power, engineering and environmental factors should be carefully considered throughout a nuclear power plant project, especially during the planning stages. This paper discusses the major environmental aspects of a nuclear power plant project from site selection to retirement. During the site selection process, both engineering and environmental resources must be identified and evaluated. Environmental resources include areas that support agricultural or aquatic commercial activities, habitats for commercial or endangered species, population centers, transportation systems, and recreational areas. Also, during the site selection process, the potential impacts of both construction and operating activities must be considered. In addition to the area actually disturbed by construction, construction activities also affect local services, such as transportation systems, housing, school systems, and other social services. Since nuclear power plants use a 'clean fuel,' generally the most significant operating activity having a potential environmental impact is the discharge of cooling water. The potential effect of this discharge on commercial activities and sensitive habitats should be thoroughly evaluated. Lastly, the method of decommissioning can affect long-range land use planning and should therefore be considered during the planning process.

    1996-01-01

    Various geometrical aspects of quantum spaces are presented showing the possibility of building physics on quantum spaces. In the first chapter the authors give the motivations for studying noncommutative geometry and also review the definition of a Hopf algebra and some general features of the differential geometry on quantum groups and quantum planes. In Chapter 2 and Chapter 3 the noncommutative version of differential calculus, integration and complex structure are established for the quantum sphere S 1 2 and the quantum complex projective space CP q (N), on which there are quantum group symmetries that are represented nonlinearly, and are respected by all the aforementioned structures. The braiding of S q 2 and CP q (N) is also described. In Chapter 4 the quantum projective geometry over the quantum projective space CP q (N) is developed. Collinearity conditions, coplanarity conditions, intersections and anharmonic ratios is described. In Chapter 5 an algebraic formulation of Reimannian geometry on quantum spaces is presented where Riemannian metric, distance, Laplacian, connection, and curvature have their quantum counterparts. This attempt is also extended to complex manifolds. Examples include the quantum sphere, the complex quantum projective space and the two-sheeted space. The quantum group of general coordinate transformations on some quantum spaces is also given

  17. Molecular radiation biology: Future aspects

    International Nuclear Information System (INIS)

    Hagen, U.

    1990-01-01

    Future aspects of molecular radiation biology may be envisaged by looking for unsolved problems and ways to analyse them. Considering the endpoints of cellular radiation effects as cell inactivation, chromosome aberrations, mutation and transformation, the type of DNA damage in the irradiated cell and the mechanisms of DNA repair as excision repair, recombination repair and mutagenic repair are essential topics. At present, great efforts are made to identify, to clone and to sequence genes involved in the control of repair of DNA damage and to study their regulation. There are close relationships between DNA repair genes isolated from various organisms, which promises fast progress for the molecular analysis of repair processes in mammalian cells. More knowledge is necessary regarding the function of the gene products, i.e. enzymes and proteins involved in DNA repair. Effort should be made to analyse the enzymatic reactions, leading to an altered nucleotide sequence, encountered as a point mutation. Mislead mismatch repair and modulation of DNA polymerase might be possible mechanisms. (orig.)

  18. Nutritional aspects of irradiated shrimp

    Data available in the literature on the nutritional aspects of irradiated shrimp are reviewed and the indication is that irradiation of shrimp at doses up to about 3.2 kGy does not significantly affect the levels of its protein, fat, carbohydrate and ash. There are no reports on the effect of irradiation of shrimp above 3.2 kGy on these components. Limited information available indicates that there are some minor changes in the fatty acid composition of shrimp as a result of irradiation. Irradiation also causes some changes in the amino acid composition of shrimp; similar changes occur due to canning and hot-air drying. Some of the vitamins in shrimp, such as thiamine, are lost as a result of irradiation but the loss is less extensive than in thermally processed shrimp. Protein quality of shrimp, based on the growth of rats as well as that of Tetrahymena pyriformis, is not affected by irradiation. No adverse effects attributed to irradiation were found either in short-term or long-term animal feeding tests

    Full Text Available Enacted in 1966 by the Law 5.107 and currently dictated by the Law 8.036/90, the employee's dismissal fund (FGTS works as a social nature fund to defray the housing and infrastructure system, and also to help the helplessness worker. Every monthly payment, compulsorily paid by the employer to every employee hired under employment laws (CLT, is deposited at CEF where the balance is updated by the Reference Rate (TR plus an annual average interest rate of 3%. Since 1999, due to the gradual reduction of the Selic - the interest rate from which the TR is extracted - the employee's FGTS balance is being partially eroded for this monetary adjustment does not offset the inflation rate at some periods. This has entailed a surging amount of lawsuits with the aim of reverting occasional losses by the CLT employees in their FGTS accounts. This paper discusses the subject in the light of the workers' pleas and arguments, with special emphasis on its aspects and potential decisions on the subject.

    The scientific community is very interested in the biological aspects of gender disorders and sexual orientation. There are different levels to define an individual's sex: chromosomal, gonadic, and phenotypic sex. Concerning the psychological sex, men and women are different by virtue of their own gender identity, which means they recognize themselves as belonging to a determinate sex. They are different also as a result of their own role identity, a set of behaviors, tendencies, and cognitive and emotional attitudes, commonly defined as "male" and "female". Transsexuality is a disorder characterized by the development of a gender identity opposed to phenotypic sex, whereas homosexuality is not a disturbance of gender identity but only of sexual attraction, expressing sexual orientation towards people of the same sex. We started from a critical review of literature on genetic and hormonal mechanisms involved in sexual differentiation. We re-examined the neuro-anatomic and functional differences between men and women, with special reference to their role in psychosexual differentiation and to their possible implication in the genesis of homosexuality and identity gender disorders. Homosexuality and transsexuality are conditions without a well defined etiology. Although the influence of educational and environmental factors in humans is undeniable, it seems that organic neurohormonal prenatal and postnatal factors might contribute in a determinant way in the development of these two conditions. This "organicistic neurohormal theory" might find support in the study of particular situations in which the human fetus is exposed to an abnormal hormonal environment in utero.

    Compact stellarators could combine the good confinement and high beta of a tokamak with the inherently steady state, disruption-free characteristics of a stellarator. Two U.S. compact stellarator facilities are now in the conceptual design phase: the National Compact Stellarator Experiment (NCSX) and the Quasi- Poloidal Stellarator (QPS). NCSX has a major radius of 1.4 m and a toroidal field up to 2 T. The primary feature of both NCSX and QPS is the set of modular coils that provide the basic magnetic configuration. These coils represent a major engineering challenge due to the complex shape, precise geometric accuracy, and high current density of the windings. The winding geometry is too complex for conventional hollow copper conductor construction. Instead, the modular coils will be wound with flexible, multi strand cable conductor that has been compacted to a 75% copper packing fraction. Inside the NCSX coil set and surrounding the plasma is a highly contoured vacuum vessel. The vessel consists of three identical, 120 deg. segments that are bolted together at double sealed joints. The QPS device has a major radius of 0.9 m, a toroidal field of 1 T, and an aspect ratio of only 2.7. Instead of an internal vacuum vessel, the QPS modular coils will operate in an external vacuum tank. (author)

    Peacekeeping operations are but one aspect of the systems of peace that have evolved over the past seven decades in a world that is riven with violence of all kinds. With the end of cold war in the late eighties of the last century we have come to see much intrastate violence, in addition to usual interstate hostilities and war, arising out of religious, political, ethnic and economic differences between people. In the changed scenario peacekeeping operations have become complex politico-military-humanitarian efforts. A soldier, trained for conventional military operations, is obliged to participate in the unconventional operations of waging peace in alien lands often in volatile and violent situations and in the process he stands to get exposed to widely variable demands for adjustment that have the potential to bring to the fore many maladaptive responses. Peacekeeping operations also have the potential to offer opportunities for growth and resilience. India is a major player in peacekeeping activities for well over sixty years all over the world. It is necessary for the commanders and mental health professionals to understand the multifarious factors that impinge on the peacekeeping soldier's mind and the emerging patterns of responses thereof for effective management trained manpower and fulfillment of mission objectives.

    2014-01-01

    This review is focused on the general mechanisms of metal toxicity in humans. The possible and mainly confirmed mechanisms of their action are discussed. The metals are divided into four groups due to their toxic effects. First group comprises of metal ions acting as Fenton reaction catalyst mainly iron and copper. These types of metal ions participate in generation of the reactive oxygen species. Metals such as nickel, cadmium and chromium are considered as carcinogenic agents. Aluminum, lead and tin are involved in neurotoxicity. The representative of the last group is mercury, which may be considered as a generally toxic metal. Fenton reaction is a naturally occurring process producing most active oxygen species, hydroxyl radical: Fe(2+) + He2O2 ↔ Fe(3+) + OH(-) + OH(•) It is able to oxidize most of the biomolecules including DNA, proteins, lipids etc. The effect of toxicity depends on the damage of molecules i.e. production site of the hydroxyl radical. Chromium toxicity depends critically on its oxidation state. The most hazardous seems to be Cr(6+) (chromates) which are one of the strongest inorganic carcinogenic agents. Cr(6+) species act also as oxidative agents damaging among other nucleic acids. Redox inactive Al(3+), Cd(2+) or Hg(2+) may interfere with biology of other metal ions e.g. by occupying metal binding sites in biomolecules. All these aspects will be discussed in the review.

    Over the last three decades photodynamic therapy (PDT) has been developed to a useful clinical tool, a viable alternative in the treatment of cancer and other diseases. Several disciplines have contributed to this development: chemistry in the development of new photosensitizing agents, biology in the elucidation of cellular processes involved in PDT, pharmacology and physiology in identifying the mechanisms of distribution of photosensitizers in an organism, and, last but not least, physics in the development of better light sources, dosimetric concepts and construction of imaging devices, optical sensors and spectroscopic methods for determining sensitizer concentrations in different tissues. Physics and biophysics have also helped to focus on the role of pH for sensitizer accumulation, dose rate effects, oxygen depletion, temperature, and optical penetration of light of different wavelengths into various types of tissue. These are all important parameters for optimally effective PDT. The present review will give a brief, physically based, overview of PDT and then discuss some of the main biophysical aspects of this therapeutic modality.

    2005-01-01

    Transmembrane signaling is one of the most significant cell biological events in the life and death of cells in general and lymphocytes in particular. Until recently biochemists and biophysicists were not accustomed to thinking of these processes from the side of a high number of complex biochemical events and an equally high number of physical changes at molecular and cellular levels at the same time. Both types of researchers were convinced that their findings are the most decisive, having higher importance than the findings of the other scientist population. Both casts were wrong. Life, even at cellular level, has a number of interacting physical and biochemical mechanisms, which finally build up the creation of an "excited" cell that will respond to particular signals from the outer or inner world. This book handles both aspects of the signalling events, and in some cases tries to unify our concepts and help understand the signals that govern the life and death of our cells. Not only the understanding, bu...

    Full Text Available Multiple sclerosis is the most common inflammatory, chronic and degenerative condition of the central nervous system, and represents the first cause of disability in young adults. In Mexico, 11 to 20 out of every 100 000 people suffer from this disease. The causes of multiple sclerosis remain unknown, but several theories have been proposed on its origin: the interaction of environmental factors, viral infectious factors and genetic and immune susceptibility of each individual patient, which induce an autoimmune response and promote neuronal/axonal degeneration. In this review, the immune reaction main components and neurodegeneration present in multiple sclerosis are analyzed, as well as the inflammatory cascade associated with demyelination. Available treatments’ main purpose is to modulate aspects related to the adaptive immune response (B and T cells. The therapeutic challenge will be antigen-specific immune-tolerance induction, for example, with the use of tolerance protocols with peptides or DNA or nanoparticles vaccines. Future therapies should aim to control innate components (microglia, macrophages, astrocytes and to promote remyelination. To optimize the treatment, a combined therapeutic approach targeting the control of inflammatory and neurodegenerative components of the disease and monitoring of biomarkers will be necessary.

    The theoretical aspects of thermonuclear fusion induced by laser are discussed. After outlining the basic features and the energetics of laser fusion in the chapter 1, various non-linear mechanisms responsible for an enhanced absorption of laser energy into the plasma and the stimulated scattering processes which hinder the absorption are discussed in the second chapter on laser plasma interactions. The third chapter on gas dynamics and the shock phenomena presents the mathematical formulation of the compression to high densities of the core of the pellet for its implosion. A hydrodynamic model developed to stimulate the evolution of laser heated symmetric plasma is outlined in the chapter four on numerichigly relativistic noninteracting particles, regular bouncing states may occur at high densities, or at high temperatures. The latter case is considered in details for the collapse phase of a hot universe; lepton pair creation may completely decelerate the collapse of a hot hadronic plasma, provided the observational parameters, the Hubble constant Hsub(deg), the matter parameter Ωsub(deg) and the deceleration parameter qsub(deg) satisfy certain constraint conditions

    Differential Geometry is a wide field. We have chosen to concentrate upon certain aspects that are appropriate for an introduction to the subject; we have not attempted an encyclopedic treatment. Book II deals with more advanced material than Book I and is aimed at the graduate level. Chapter 4 deals with additional topics in Riemannian geometry. Properties of real analytic curves given by a single ODE and of surfaces given by a pair of ODEs are studied, and the volume of geodesic balls is treated. An introduction to both holomorphic and Kähler geometry is given. In Chapter 5, the basic properties of de Rham cohomology are discussed, the Hodge Decomposition Theorem, Poincaré duality, and the Künneth formula are proved, and a brief introduction to the theory of characteristic classes is given. In Chapter 6, Lie groups and Lie algebras are dealt with. The exponential map, the classical groups, and geodesics in the context of a bi-invariant metric are discussed.

    We investigate cosmological aspects of spontaneous baryogenesis driven by a scalar field, and present general constraints that are independent of the particle physics model. The relevant constraints are obtained by studying the backreaction of the produced baryons on the scalar field, the cosmological expansion history after baryogenesis, and the baryon isocurvature perturbations. We show that cosmological considerations alone provide powerful constraints, especially for the minimal scenario with a quadratic scalar potential. Intriguingly, we find that for a given inflation scale, the other parameters including the reheat temperature, decoupling temperature of the baryon violating interactions, and the mass and decay constant of the scalar are restricted to lie within ranges of at most a few orders of magnitude. We also discuss possible extensions to the minimal setup, and propose two ideas for evading constraints on isocurvature perturbations: one is to suppress the baryon isocurvature with nonquadratic scalar potentials, another is to compensate the baryon isocurvature with cold dark matter isocurvature by making the scalar survive until the present.

    2012-05-01

    For more than 10 years integrated care has been an inherent part of the German healthcare system. The aims of selective contracts are to minimize interface problems between outpatient and inpatient sectors, generalist und specialist care as well as to intensify competition. Despite repeated efforts by the legislator, comprehensive integrated healthcare is still limited to a few flagship projects. This is mainly due to low incentives on the part of both suppliers and customers. Therefore, this article focuses on the economic aspects of integrated care. From a theoretical perspective, integrated care improves efficiency in the healthcare sector by reducing interface problems and asymmetric information as well as by intensifying competition. In practice, however, there are a number of obstacles to implementation. Particularly noteworthy are the financial difficulties in addition to problems regarding sectoral budgeting and the long-term nature of investments. However, the political environment and thus the financial arrangements within the statutory health insurance seem to be more important for further development of integrated care in Germany than the financing issues.

    Full Text Available Psychopathy is characterised by emotional disturbances that affect interpersonal behaviour and decision-making. The objective of this paper is to review the most recent contributions to the field of neuroscience of psychopathy and the implications that this disorder has on the criminal legal field. In regards to this last aspect, we evaluate the issue of psychopaths’ accountability and the incidence of psychopathy in many other penal institutions. In terms of the contributions of neuroscience, we will focus on the orbitofrontal (ofPFC and ventromedial (vmPFC regions of the frontal lobes and on the amygdala. Data spanning from the nineteenth century to the present indicate that damage to the ofPFC and vmPFC is the basis of behaviours that have been referred to as pseudopsychopathic. The earlier during brain development the damage occurs, the more likely these behaviours will resemble those of psychopaths. The damage to the amygdala is rather related to impairments in the ability to distinguish facial expressions of fear and the capacity to feel emotions. Damage to ofPFC, vmPFC, and amygdala are highly relevant to the expression of pseudopsychopathic behaviours.

    US anti-abortion groups have used misinformation on the long-term psychological impact of induced abortion to advance their position. This article reviews the available research evidence on the definition, history, cultural context, and emotional and psychiatric sequelae of induced abortion. Notable has been a confusion of normative, transient reactions to unintended pregnancy and abortion (e.g., guilt, depression, anxiety) with serious mental disorders. Studies of the psychiatric aspects of abortion have been limited by methodological problems such as the impossibility of randomly assigning women to study and control groups, resistance to follow-up, and confounding variables. Among the factors that may impact on an unintended pregnancy and the decision to abort are ongoing or past psychiatric illness, poverty, social chaos, youth and immaturity, abandonment issues, ongoing domestic responsibilities, rape and incest, domestic violence, religion, and contraceptive failure. Among the risk factors for postabortion psychosocial difficulties are previous or concurrent psychiatric illness, coercion to abort, genetic or medical indications, lack of social supports, ambivalence, and increasing length of gestation. Overall, the literature indicates that serious psychiatric illness is at least 8 times more common among postpartum than among postabortion women. Abortion center staff should acknowledge that the termination of a pregnancy may be experienced as a loss even when it is a voluntary choice. Referrals should be offered to women who show great emotional distress, have had several previous abortions, or request psychiatric consultation.

  16. Environmental aspects of nuclear power

    Ward, D.P.

    1988-01-01

    Nuclear power provides the world with an important option for generating electricity. To successfully and safely utilize this power, engineering and environmental factors should be carefully considered throughout a nuclear power plant project, especially during the planning stages. This paper discusses the major environmental aspects of a nuclear power plant project from site selection to retirement. During the site selection process, both engineering and environmental resources must be identified and evaluated. Environmental resources include areas that support agricultural or aquatic commercial activities, habitats for commercial or endangered species, population centers, transportation systems, and recreational areas. Also during the site selection process, the potential impacts of both construction and operating activities must be considered. In addition to the area actually disturbed by construction, construction activities also affect local services, such as transportation systems, housing, school systems, and other social services. Since nuclear power plants use a ''clean fuel,'' generally the most significant operating activity having a potential environmental impact is the discharge of cooling water. The potential effect of this discharge on commercial activities and sensitive habitats should be thoroughly evaluated. Lastly, the method of decommissioning can affect long-range land use planning and should therefore be considered during the planning process

The principles of these methods are. expressed in a symmetrical form with respect to the two sides of the potential barrier; this constitutes a proof of the fact that the transmission coefficient is path direction independent. The numerical application is carried out on several examples and the results are compared to those provided by the WKB method.

    1989-09-01

    The accident at Chernobyl revealed that there were shortcomings and gaps in the existing international mechanisms and brought home to governments the need for stronger measures to provide better protection against the risks of severe accidents. The main thrust of international co-operation with regard to nuclear safety issues is aimed at achieving a uniformly high level of safety in nuclear power plants through continuous exchanges of research findings and feedback from reactor operating experience. The second type of problem posed in the event of an accident resulting in radioactive contamination of several countries relates to the obligation to notify details of the circumstances and nature of the accident speedily so that the countries affected can take appropriate protective measures and, if necessary, organize mutual assistance. Giving the public accurate information is also an important aspect of managing an emergency situation arising from a severe accident. Finally, the confusion resulting from the unwarranted variety of protective measures implemented after the Chernobyl accident has highlighted the need for international harmonization of the principles and scientific criteria applicable to the protection of the public in the event of an accident and for a more consistent approach to emergency plans. The international conventions on third party liability in the nuclear energy sector (Paris/Brussels Conventions and the Vienna Convention) provide for compensation for damage caused by nuclear accidents in accordance with the rules and jurisdiction that they lay down. These provisions impose obligations on the operator responsible for an accident, and the State where the nuclear facility is located, towards the victims of damage caused in another country

    Singh, H.

    1990-06-01

    Mango is an important and very popular tropical fruit. Because of its short shelf life, however, its use is restricted to the areas of production. Since mango is a climacteric fruit, it is possible to extend its shelf life by delaying the ripening process and senescence by irradiation. The ripening process is very complex: it appears that the radiation-induced delay in ripening may be mediated through the inhibition of the enzyme(s) involved in ethylene production. The dose required for shelf-life extension is ≤1.5 kGy. Higher doses can lead to scalding, flesh darkening and development of hollow pockets. This review focuses on the chemical aspects of radiation-induced shelf-life extension of mangoes. At the low irradiation doses required for this shelf-life extension (≤1.5 kGy), the chemical effects are negligible. Irradiation does not affect the carotenoid levels, and has only a minor effect on the vitamin C level in a few mango varieties. No significant differences in the free and total (hydrolyzed) amino acids, or the protein content of Kent mangoes, have been detected between irradiated and unirradiated samples. During ripening of the mangoes the reducing sugar and the total sugar levels increase, but in the majority of the mango varieties these levels remain very similar in irradiated and unirradiated samples. There are some differences in the volatile compounds between irradiated and unirradiated Kent mangoes; however, these differences have no apparent effect on the taste and flavor of the irradiated mangoes

    One of the modern economy models is circular economy in which wastes should be considered as resource and used in an efficient and sustainable way. This also concerns to metals included in scraps. However, the need for metal recovery from waste is not only the result of the latest economic trends but also the result of large and constantly changing demand for metals. Shrinking natural sources of metals, concentrations of ores in small number of countries in the world and resulting from this dependence on import, geopolitical situation, new technologies demands are only a few most important determinants that have been changing the structure of the metal market over years. In this chapter, authors focused on the presentation of economic aspects of metal recovery from various sources. The chapter presents the characteristic of metal market elements (supply, demand and price) and changes that took place over decades, underlining the structure of precious and highly desirable metal market elements. Balance between the demand and supply ensures price stability and rationalizes inflation. However, growing demand on many means that secure supply chains, such as recycling and material recovery, are essential to ensure continuity in the supply chain and guarantee unrestricted technological progress and innovation. The data included in this chapter presents also the concentration of different metals and group of metals in wastes pointing that recycling of waste can become one of the possibilities of acquiring missing and critical metals. Metal-laden wastes include a few groups: waste electrical and electronic equipments, catalysts of different application, introduced on chemical, petrochemical or automotive market, galvanic wastes and wastewaters. The profitability assessment of recycling processes is very complicated. Nevertheless cited data shows that profitability of recovery depends on the metal analyzed and the type of waste. It must be underline that an optimized

  2. ASPECTS OF ECOFEMINISM IN ROMANIA

    2014-07-01

    Full Text Available Ecofeminism can be understood as the relationship between the manner in which women are treated in society and on how the environment is treated and protected. Ecofeminism starts from the idea according to which "nature is a feminist issue". The explanation for this is based on the feminist philosophy according to which the connection between woman and nature is a strong one, due to the fact that she is the one who gives birth, thus helping nature to regenerate itself. Without women, female plants and animals, the planet could not develop, perpetuate and the end would be death. Furthermore, another explanation related to the first is that animals and people in their capacity as mothers are able to provide a greater amount of love, care, protection, both to their offspring and to nature. This paper aims to analyze the manner in which women are harmed by the environmental degradation in Romania and also the principles that have governed and still govern the current economy. Nowadays society is lead largely by male gender persons. The main accusations against current policies is that they seek concrete and immediate results, such as those related to economic growth, inflation rate etc. in terms of strictly economic indicators such as: gross domestic product, net national product, gross national product etc.. On the contrary, ecofeminist policies suggest that the emphasis should be placed on quality of life issues, which within itself analyzes both economic and also social and environmental aspects. Is not this the reproach for decades now that is brought to current economic policies? The fact that they do not take into account issues related to environmental degradation, in time led to negative consequences in the world whose costs are unimaginable.

    Full Text Available On the basis of the latest statistics, the author estimates the present share of first- and second-generation immigrants in Slovenia’s population. After examining the quantity and intensity of those public efforts in Slovenia that have been focused on unresolved problems of the immigrants’ social and cultural integration, she continues to question the equality of immigrant minorities in Slovenia, and the sufficiency of the existing programs aimed at facilitating their integration with Slovenian society at large. She explains her doubts about the general assumption that a very clear distinction should be made between the rights of the autochthonous minorities and those of the immigrant ones as far as their special protection is concerned. In the third section of this article, the author discusses the social-ethnic stratification of Slovenian society and tries to look into the psychological background of the nationality/ethnicity statistics. She presents some aspects of the immigrants’ daily experience in Slovenian social, cultural, educational and working milieu, and points to the authorities’ attitude toward them. She comments on the burning issue of the “deleted residents”, and illustrates it with the experience of one of the persons involved. The fourth section, in which the most regular symptoms of Slovenian xenophobia are presented, consists of first-hand observations and focuses on the daily human attitude of the national majority towards the immigrant minorities. Finally the author compares the nature of the specific needs of Slovenians as a “European national minority” with the needs of the immigrant minorities in Slovenia.

    The injury to haemopoietic and lymphatic tissues produced by ionizing irradiation in various species of mammals including man is one of the major features of the biological effects of radiation (Bond et al. 1965,' Cottier, 1961). At the moment of injury and for a short time thereafter relatively little morphological evidence of cell damage in bone marrow other than cessation of cell division and DNA synthesis is seen. Within a few hours, however, depending on the level of exposure, major destruction of red bone marrow tissue can occur. In this chapter the histologic changes in bone marrow are summarized for correlation with the functional aspects of the change in the target tissue, particularly its cell renewal features and where possible the remarkable flux or migration of cells through bone marrow and lymphatic tissues. This latter topic of cellular traffic represents the outcome of extensive physiological studies on haemopoiesis and lymphopoiesis by mammalian radiobiologists. The initial injury, the structural changes and the physiological consequences are the first half of the radiation injury sequence. Regeneration also has morphological features of major importance to the understanding of radiation haematology. It is common to discuss radiation effects on biological materials from the point of view of external or internal sources of exposure. In addition exposure rate, whole body or partial body, type and quality of the ionizing source are features that must be taken into account. While these features are extremely important, the simplest approach to understanding histologic effects on the bone marrow is to assume acute penetrating whole-body exposure in the lethal range. With this background the differences related to variations in the conditions of exposure can usually be understood. The individual human or animal organism receiving the exposure must also be considered in the final outcome of the experience because age, sex, nutritional status and presence

    Full Text Available The purpose of this article is to outline the main economical and social benefits that can be obtained by adopting an ethical attitude of the organisations which use a performant environmental management. From the idea that the human being is the master of nature, it was passed to the view according to which the human being must ensure a balance between consumption and the use of resources. In order to achieve our goal we identified the factors that lead to long term or even permanent destructive effects over the environment and we briefly present the reasons for which the organizations adopt and implement environmental management systems. Also, the difficulties encountered in implementing environmental strategies have been briefly enumerated and the competitive and economic advantages that can be achieved by adopting an efficient environmental management and the main reasons that grant to the environmental management a special significance were exposed. This theoretical paper emphasizes the importance of the adoption by organizations of a "green behavior" and reveals correlations between sustainability, economic growth and environmental performance in organizations. The analysis of the ethical aspects of environmental management shows the links that can be created between the development of an ethical culture of organizations and the achievement of the environmental excellence. The research provides an overview of the concept of environmental ethics and encloses it within the scope of environmental management. Someone needs to explain why an increasing number of organizations, both large and small, are setting up environmental management systems, making environmental investments and reducing risks over and beyond legal requirements, even when the benefits are not at all obvious, even in the long run. Also, this paper provides some practical examples of organizations environmental problems and points out how these organizations adapted their

    Full Text Available The world practice of using agrochemicals for long periods, in an indiscriminated and abusive way, has been a concern of the authorities involved in public health and sustainability of the natural resources, as a consequence of environmental contamination. Agrochemicals refer to a broad range of insecticides, fungicides and herbicides, and among them stands out atrazine, a herbicide intensively used in sugarcane, corn and sorghum cultures, among others. Researches have demonstrated that atrazine has toxic effects in algae, aquatic plants, aquatic insects, fishes and mammals. Due to the toxicity and persistence of atrazine in the environment, the search of microbial strains capable of degrading it is fundamental to the development of bioremediation processes, as corrective tools to solve the current problems of the irrational use of agrochemicals. This review relates the main microbial aspects and research on atrazine degradation by isolated microbial species and microbial consortia, as well as approaches on the development of techniques for microbial removal of atrazine in natural environments.A prática mundial do uso de agroquímicos por períodos extensos, de maneira indiscriminada e abusiva, tem mobilizado as autoridades envolvidas em saúde pública e sustentabilidade de fontes naturais, como uma conseqüência da contaminação ambiental. Agroquímicos referem-se a uma ampla variedade de inseticidas, fungicidas e herbicidas, entre estes a atrazina, um herbicida intensivamente usado em culturas de cana-de-açúcar, milho, sorgo, entre outros. Pesquisadores têm demonstrado que a atrazina tem efeitos tóxicos em algas, plantas aquáticas, insetos aquáticos, peixes e mamíferos. Devido à toxicidade e à persistência da atrazina no ambiente, a busca de linhagens microbianas capazes de degradá-la é fundamental para o desenvolvimento de processos de biorremediação, com uma ferramenta corretiva para solucionar problemas decorridos do uso

Another important aspect of clinical efficacy of medications in space is the stability of pharmaceuticals. As the U.S. space program is moving toward extended Space Shuttle flights and beyond, to space station missions and planetary explorations, understanding how space flight affects organ systems and clinical pharmacology is necessary to optimize pharmacotherapeutics in space and ensure adequate safety and health of crewmembers.

    radio systems. From the point of view Working Group 2 of the COST 296 Action, interest lies with effects associated

    with propagation via the ionosphere of signals within the HF band. Several aspects are covered in this paper:

    a The directions of arrival and times of flight of signals received over a path oriented along the trough have

    been examined and several types of propagation effects identified. Of particular note, combining the HF observations

    with satellite measurements has identified the presence of irregularities within the floor of the trough that

    result in propagation displaced from the great circle direction. An understanding of the propagation effects that

    result in deviations of the signal path from the great circle direction are of particular relevance to the operation

    of HF radiolocation systems.

    ionosphere (i.e. those regions of the ionosphere located poleward of, and including, the mid-latitude trough

Pour commencer ce texte sur la vision institutionnaliste de l’économie, je propose d’interroger d’abord l’attitude actuelle des économistes, en particulier celle de ceux qui soutiennent la vision dominante actuellement en science économique, ainsi que les thèses qui nous mènent à la révision du rôle - pour ne pas dire au retrait - de l’État, ce qui se traduit notamment par le développement de la précarité d’emploi, la hausse du chômage et l’exclusion que nous constatons tous depuis quelques décennies. Je commence donc par présenter ma vision des thèses dominantes en regard de la redéfinition du rôle de l’État et de l’entreprise privée dans le contexte économique actuel, avant de présenter quelques aspects de la vision non orthodoxe, mais tout à fait pertinente à mes yeux, à savoir celle des économistes institutionnalistes, qui suscite nombre de questions par rapport à la vision dominante.

    1982-06-01

    Results are presented of a literature review to identify social and psychological aspects of abortion. The literature does not provide a true profile of women requesting abortions, but some characteristics emerge. Reasons for requesting abortion include economic problems, difficult previous pregnancies, general medical contraindications to pregnancy, marital conflicts, feelings of loneliness, professional aspirations, problems with existing children, and feelings of insecurity about the future. However, the same feelings are found among women carrying their pregnancies to term. Unplanned pregnancies are more common during periods of depression. Most authors have found about 1/2 of women seeking abortions to be single and about 1/2 to be under 25 years old. Religion does not appear to be a determining factor. 1 study of psychological factors in abortion seekers found that a large number of single women seeking abortion had suffered traumatic experiences in childhood and were seeking security in inappropriate amorous relationships. Helene Deutsch stressed the destructive impulses latent in all pregnancies. Others have cited the ambivalence of the desire for pregnancy and feelings of loss after abortion. Studies published after legalization of abortion in the US and France however have stressed the nearly total absence of moderate or severe psychiatric symptoms after abortion. Responses immediately after the abortion may include feelings of relief, guilt, indifference, or ambivalence. Secondary affects appear minor to most authors. Psychological effects do not appear to be influenced by age, marital status, parity, intelligence, occupation, existence of a later pregnancy, or concommitant sterilization. "Premorbidity" and coercion by spouse or family were most closely associated with psychological symptoms. Numerous authors have found about twice as many negative reactions among women undergoing abortion for medical reasons. Most patients undergoing abortions for

This report is intended to be used by environmental staff in the evaluation of BSC work packages during the annual risk-based planning process. This report shall be fully reviewed and revised annually during the annual work planning process to reflect changes in BSC operations, facilities, and scope of work. Planned BSC work will be evaluated to determine if the work is covered by a previously defined activity, product or service (see Table 2); if work activities require redefinition or addition of a new activity; and if the significant evaluation for each environment aspect is still valid based on scope of planned work. New workscope initiated during the fiscal year through the Baseline Change Proposal process (i.e., not as part of the annual work plan) also will be reviewed for new environmental aspects and determination of whether the new workscope would change the significance rating of any environmental aspect.

  20. Initial Performance of the Aspect System on the Chandra Observatory: Post-Facto Aspect Reconstruction

    Science.gov (United States)

    Aldcroft, T.; Karovska, M.; Cresitello-Dittmar, M.; Cameron, R.

    2000-01-01

    The aspect system of the Chandra Observatory plays a key role in realizing the full potential of Chandra's x-ray optics and detectors. To achieve the highest spatial and spectral resolution (for grating observations), an accurate post-facto time history of the spacecraft attitude and internal alignment is needed. The CXC has developed a suite of tools which process sensor data from the aspect camera assembly and gyroscopes, and produce the spacecraft aspect solution. In this poster, the design of the aspect pipeline software is briefly described, followed by details of aspect system performance during the first eight months of flight. The two key metrics of aspect performance are: image reconstruction accuracy, which measures the x-ray image blurring introduced by aspect; and celestial location, which is the accuracy of detected source positions in absolute sky coordinates.

  20. Modeling Submarine Lava Flow with ASPECT

    Science.gov (United States)

    Storvick, E. R.; Lu, H.; Choi, E.

    2017-12-01

    Submarine lava flow is not easily observed and experimented on due to limited accessibility and challenges posed by the fast solidification of lava and the associated drastic changes in rheology. However, recent advances in numerical modeling techniques might address some of these challenges and provide unprecedented insight into the mechanics of submarine lava flow and conditions determining its wide-ranging morphologies. In this study, we explore the applicability ASPECT, Advanced Solver for Problems in Earth's ConvecTion, to submarine lava flow. ASPECT is a parallel finite element code that solves problems of thermal convection in the Earth's mantle. We will assess ASPECT's capability to model submarine lava flow by observing models of lava flow morphology simulated with GALE, a long-term tectonics finite element analysis code, with models created using comparable settings and parameters in ASPECT. From these observations we will contrast the differing models in order to identify the benefits of each code. While doing so, we anticipate we will learn about the conditions required for end-members of lava flow morphology, for example, pillows and sheet flows. With ASPECT specifically we focus on 1) whether the lava rheology can be implemented; 2) how effective the AMR is in resolving morphologies of the solidified crust; 3) whether and under what conditions the end-members of the lava flow morphologies, pillows and sheets, can be reproduced.

    2007-01-01

    This comprehensive article summarises the commercial aspects of a study made by the German Association of Electrical, Electronic and Information Technologies VDE on the topic of decentralised energy supply in the year 2020. In a previous article, the technical aspects were examined. This article looks at the findings in connection with commercial aspects of the production of power in decentralised facilities including those using renewable sources of energy. The potential of these forms of electricity generation for the year 2020 is looked at both from the political and economical points of view. The general conditions prevailing for the implementation of decentralised power production in Germany such as the Renewable Energy Law and legislation on combined heat and power generation are discussed. The influence of electricity tariffs and competition in the market is examined, as are various scenarios and concepts for the supply of both power and heating energy. Ways of providing a sustainable energy supply without having to subsidise particular concepts are discussed

  3. Transport in a small aspect ratio torus

    International Nuclear Information System (INIS)

    White, R.B.; Gates, D.A.; Mynick, H.E.

    2005-01-01

    Transport theory in toroidal devices often assumes large aspect ratio and also assumes the poloidal field is small compared to the toroidal field. These assumptions result in transport which in the low collision rate limit is dominated by banana orbits, giving the largest collisionless excursion of a particle from an initial flux surface. However in a small aspect ratio device the gyro radius may be larger than the banana excursion, resulting in significant deviations from the standard neoclassical predictions. In this paper we report numerical simulation of diffusion in low and high beta low aspect ratio equilibria. We also sketch an analytic theory. The diffusion, which we refer to as omniclassical, is a combination of neoclassical and properly averaged classical effects, and can be two or three times the neoclassical value. Good agreement of the analytic theory with numerical simulations is obtained. (author)

    The topic of energy crops, namely of those crops designed to produce biomass to transform into ethanol, has been explored, in Italy and abroad, in all its technical and agronomical aspects. The microeconomic aspect, including the evaluation of convenience for the farmer in adopting such crops, is, on the contrary, less well researched. RENAGRI has developed a research methodology able to give information about the level of convenience of two energy crops (Sweet Sorghum and Topinambour) and has applied it to different Italian agricultural situations, in order to verify the existence of conditions favourable to the cultivation of the two crops, or to indicate the necessity of eventual subvention.

    Pérez, José-Philippe; Pujol, Olivier

    2015-01-01

    This paper revisits the famous Foucault's pendulum by highlighting two often-disregarded aspects in mechanics courses. The first one concerns the existence of a local accelerated reference frame to express the law of dynamics without the Coriolis force. The second aspect deals with the geometrical phase that appears in pendulum dynamics. This last point, which could appear banal, should be related to analogous consideration in quantum physics. It is also linked to vectorial parallel transport of the pendulum angular momentum eigenvector. Numerical simulations with MATLAB are proposed. (paper)

    The aim of this work, consists in the examination of the behaviour of radioactive aerosols produced in the atmosphere by nuclear explosions, in order to deduce the most general laws governing atmospheric circulation and diffusion. After having given a general table of the radioactive aerosols present the authors consider the validity and the precision of the measurement methods and the concentration of the aerosols at ground level and in the upper atmosphere, as well as their deposition on the ground. The existence is thus demonstrated of a tropospheric equatorial barrier and of discontinuous and seasonal aspects of stratosphere-troposphere transfers. The role is shown of precipitations and dry auto-filtration in the lower atmosphere cleaning processes. This work makes it possible to describe the general behaviour of dust from the stratosphere, and to improve the total radioactive contamination of the globe.

The existence is thus demonstrated of a tropospheric equatorial barrier and of discontinuous and seasonal aspects of stratosphere-troposphere transfers. The role is shown of precipitations and dry auto-filtration in the lower atmosphere cleaning processes. This work makes it possible to describe the general behaviour of dust from the stratosphere, and to improve the total radioactive contamination of the globe. (author) [French] L'objectif de ce travail consiste a examiner le comportement des aerosols radioactifs introduits dans l'atmosphere par les explosions nucleaires, pour en deduire les lois les plus generals de la circulation et diffusion atmospheriques. Apres avoir dresse un tableau d'ensemble des aerosols radioactifs presents, on examine la validite et la precision des methodes de mesure de leur concentration, au niveau du sol et en haute atmosphere, ainsi que de leur depot a la surface du sol. On met ainsi en evidence l'existence d'une barriere equatoriale tropospherique; l'aspect discontinu et saisonnier des transferts stratosphere-troposphere; le role des precipitations et de l'auto-filtration seche, dans les processus de nettoyage de la basse atmosphere. Ces etudes permettent de decrire le comportement general des poussieres d'origine stratospherique et d'ameliorer le bilan de la contamination radioactive du globe. (auteur)

    CERN Document Server

    Silari, Marco

    2001-01-01

    Radiation protection aspects relevant to medical accelerators are discussed. An overview is first given of general safety requirements. Next. shielding and labyrinth design are discussed in some detail for the various types of accelerators, devoting more attention to hadron machines as they are far less conventional than electron linear accelerators. Some specific aspects related to patient protection are also addressed. Finally, induced radioactivity in accelerator components and shielding walls is briefly discussed. Three classes of machines are considered: (1) medical electron linacs for 'conventional' radiation therapy. (2) low energy cyclotrons for production of radionuclides mainly for medical diagnostics and (3) medium energy cyclotrons and synchrotrons for advanced radiation therapy with protons or light ion beams (hadron therapy).

    Yamaguchi, M

    1989-02-01

    This study was designed to explore two aspects (mother-father; woman-man) of Masculinity-Femininity in personality. Sixty-five middle school students, 150 high school students and 219 university students were asked to rate the desirability for them, their fathers and mothers, and society of each of 45 items comprising a questionnaire which described valid characteristics of these two aspects. Analysis of the results revealed that male subjects in all age groups seemed to feel that their fathers desired them to be more masculine (i.e., father and man) than they, themselves, desired. Those of high school and university age also seemed to feel that their mothers and fathers and society desired more motherliness of them than they, themselves, desired. Female high school and university subjects seemed to feel that their fathers and mothers desired much more femininity (mother and woman) and much less masculinity (father and man) than they, themselves, desired.

  10. OCLATOR (One Coil Low Aspect Toroidal Reactor)

    Energy Technology Data Exchange (ETDEWEB)

    Yoshikawa, S.

    1980-02-01

    A new approach to construct a tokamak-type reactor(s) is presented. Basically the return conductors of toroidal field coils are eliminated and the toroidal field coil is replaced by one single large coil, around which there will be placed several tokamaks or other toroidal devices. The elimination of return conductors should, in addition to other advantages, improve the accessibility and maintainability of the tokamaks and offer a possible alternative to the search for special materials to withstand large neutron wall loading, as the frequency of changeover would be increased due to minimum downtime. It also makes it possible to have a low aspect ratio tokamak which should improve the ..beta.. limit, so that a low toroidal magnetic field strength might be acceptable, meaning that the NbTi superconducting wire could be used. This system is named OCLATOR (One Coil Low Aspect Toroidal Reactor).

    Gilbert, R.O.; Eberhardt, L.L.

    1977-01-01

    In this paper, we discuss some design aspects of transuranic field studies. Some of the principal steps in the design of such studies are given and illustrated using examples. This is followed by a review of sampling designs that have been used at nuclear detonation and safety-shot sites on the Nevada Test Site and elsewhere for estimating spatial pattern and total amounts in soil. Some design aspects of ecosystem-type transuranic studies for estimating total amounts as well as movement of transuranics between ecosystem components are also discussed. Acceptance sampling using either attributes or measurements is considered as a possible approach for deciding whether to clean up a contaminated site. Three general guidelines for the design of efficient transuranic studies are presented

  15. QCD-instantons at LHC. Theoretical aspects

    International Nuclear Information System (INIS)

    Petermann, M.

    2007-06-01

    Instantons are nonperturbative, topologically nontrivial field configurations, which occur in every nonabelian gauge theory. They can be understood as tunneling processes between topologically distinct vacua. Although being a basic theoretical aspect of the Standard Model, a direct experimental verification of instanton processes is still lacking. In this thesis the general discovery potential for QCD-instantons at the LHC is studied in detail by means of instanton perturbation theory. In this context the close correspondence between the leading instanton induced processes at HERA and at LHC becomes important. Essential aspects and differences to deep inelastic scattering can already be revealed by studying the simplest process. Based on these results inclusive cross sections are calculated including the emission of final state gluons. Compared to deep inelastic scattering, a large enhancement of the cross section is found.

  14. Linguistic aspects of writing for professional purposes

    Directory of Open Access Journals (Sweden)

    Greta Përgjegji

    2016-03-01

    Full Text Available Writing for Professional Purposes is considered as a means of communication between professionals who belong to two communities that have different languages, but share the same knowledge or expertise. The article gives a hint on how writing for specific purposes evolved to give rise to the creation of Writing for Professional Purposes. The social, cultural and cognitive aspects are an essential part of Writing for Professional Purposes since the physical act of writing cannot be considered only a result or product of the knowledge the individual possesses but also a social and cultural act. Therefore, the social and cultural aspects of writing explains the specificities and the intricacies of the effects these aspects have on writing for it is considered as an inseparable part of social and cultural groups. On the other hand, the cognitive aspect of writing explains and emphasizes the mental activities of the individual during the decision-making process while he/she is writing planning and editing their material having in mind the audience. On the same line of reasoning, writing for professional purposes in a second language means that the writer has to consider the audience twice; first, there is an audience who shares the same knowledge or expertise and second, the audience does not have the same language. Consequently, writing in another language that is not the first language with a specific jargon as well as a specific grammatical structure brings about a lot of difficulties. Hence, writing in professional contexts in the mother tongue implies only writing in a specialized version of a language already known to the writer, but writing in a target language means that the writer has to learn the target language and the specialized version of that language.

    ITER plasma control design solutions and performance requirements are strongly driven by its nuclear mission, aggressive commissioning constraints, and limited number of operational discharges. In addition, high plasma energy content, heat fluxes, neutron fluxes, and very long pulse operation place novel demands on control performance in many areas ranging from plasma boundary and divertor regulation to plasma kinetics and stability control. Both commissioning and experimental operations schedules provide limited time for tuning of control algorithms relative to operating devices. Although many aspects of the control solutions required by ITER have been well-demonstrated in present devices and even designed satisfactorily for ITER application, many elements unique to ITER including various crucial integration issues are presently under development. We describe selected novel aspects of plasma control in ITER, identifying unique parts of the control problem and highlighting some key areas of research remaining. Novel control areas described include control physics understanding (e.g., current profile regulation, tearing mode (TM) suppression), control mathematics (e.g., algorithmic and simulation approaches to high confidence robust performance), and integration solutions (e.g., methods for management of highly subscribed control resources). We identify unique aspects of the ITER TM suppression scheme, which will pulse gyrotrons to drive current within a magnetic island, and turn the drive off following suppression in order to minimize use of auxiliary power and maximize fusion gain. The potential role of active current profile control and approaches to design in ITER are discussed. Issues and approaches to fault handling algorithms are described, along with novel aspects of actuator sharing in ITER.
