    neutralizzazione dei possibili rinforzi negativi che provengono invece dai “non-giocatori”.Dans cet article, l’auteur analyse les caractéristiques de ce qu’elle a appelé « sous-culture des jeux de hasard », décelable dans certains milieux de loisirs et dans les sous-groupes de joueurs particulièrement « acharnés ». Parmi ces formes de sous-culture, l’article va identifier les règles et les sanctions, les valeurs, les comportements durables, la caractérisation des relations et des interactions, en concluant que ce qui est construit dans l'espace du jeu est un univers séparé, une «réalité extérieure» dans laquelle des nouvelles règles sont écrites et où les valeurs changent par rapport au «monde extérieur» . Il a également été possible de conclure que l'adhésion à l' «univers du jeu» - l'internalisation de ses normes, le partage de ses valeurs, le développement des relations en son sein - est un facteur de maintenance de la conduite du jeu, car cette adhésion permet d'envisager comme «normal» son propre comportement grâce à des réactions positives provenant des compagnons de jeu et à la neutralisation d’éventuelles réactions négatives provenant des «non joueurs».

  8. De Pythagore à Einstein, tout est nombre la relativité générale, 25 siècles d'histoire

    Deruelle, Nathalie

    2015-01-01

    La théorie d'Einstein de la gravitation, plus connue sous le nom de relativité générale, a maintenant 100 ans. Pour comprendre pourquoi elle supplanta la loi de Newton de l'attraction universelle, pour appréhender le changement profond qu'elle a apporté à notre perception de l'espace et du temps, bref, pour en montrer toute la grandeur, cet ouvrage remonte à la révolution scientifique du 17e siècle, qui elle-même résulte des blocages auxquels se heurtait la science d'alors, héritée des Grecs. Ce livre met l'accent sur les liens profonds qui unissent physique et mathématiques. Il met en valeur la puissance créatrice de quelques géants de la science qui, guidés certes par l'observation et l'expérience, posent néanmoins librement des hypothèses, bâtissent des théories, les élaguent, créant ainsi une trame du réel, une « réalité physique » qui trace des chemins intelligibles dans la forêt des phénomènes. Il suit donc un fil directeur qui parcourt la science depuis 2 500 ans, à sa...

    2009-01-01

    Full Text Available Charles Bovary est probablement le personnage qui a été le plus transformé par les cinéastes qui ont adapté le roman de Flaubert. Si les premiers adaptateurs l’ont traité en victime, peu à peu, le cinéma a commencé à souligner la dimension néfaste sous-jacente du personnage et à lui faire porter une large part de responsabilité dans la descente aux enfers d’Emma. Depuis Pierre Renoir, touchant et authentique, jusqu’à Gregg Edelman, le mari de Little children qui fantasme sur les photos d’une pin-up virtuelle, en passant par les images plus ou moins pathétiques ou ridicules de Van Heflin, Aribert Wäscher, Alberto Bello, Jean-François Balmer, Farooq Shaikh ou Luis-Miguel Cintra, Charles, plus que tout autre personnage du roman, a subi une incroyable métamorphose en s’ancrant dans la civilisation de chacun des pays et de chacune des décennies successives qui l’ont porté à l’écran.From the 1930s to the present, Charles Bovary is probably the most altered character in the adaptations of Flaubert’s novel. The first directors made a victim of him, but gradually, the cinema began to emphasize his deleterious dimension and attributed to him a large part of the responsibility for Emma’s grief. From Pierre Renoir, touching and authentic, to Gregg Edelman, who fantasizes on a pornographic website in Todd Field’s Little Children, the more or less pathetic or ridiculous portrayals given by Van Heflin, Aribert Wäscher,Alberto Bello, Jean-François Balmer, Farooq Shaikh or Luis-Miguel Cintra, show that more than any other character in the novel, Charles has been submitted to a serious metamorphosis by being interpreted on screen according to each country’s civilization and the successive decades of filming.

    Christine Okret

    2000-05-01

    Full Text Available Tels qu’ils existent actuellement, les procédés institutionnels de valorisation des thèses soutenues dans les universités et grands établissements français reposent sur deux circuits concomitants. En premier lieu les thèses soutenues sont déposées sous forme papier dans la bibliothèque de leur université de soutenance, où elles peuvent être consultées sur place, et prêtées par le biais du réseau de prêt entre bibliothèques. En second lieu, un exemplaire papier est transmis aux ateliers nationaux de reproduction des thèses chargés du microfichage des textes et de la diffusion systématique de ces microfiches auprès de toutes les bibliothèques universitaires. Ces deux formes de diffusion non commerciale présentent en regard des exigences des chercheurs trois inconvénients majeurs: la diffusion des thèses est géographiquement restreinte, puisque limitée aux bibliothèques universitaires; le support microfiche est jugé peu convivial; le prêt entre établissements est parfois trop lent ou onéreux, ce qui peut décourager les utilisateurs qui désirent consulter sur papier les thèses non conservées dans leur bibliothèque universitaire.

    Full Text Available Active à peine plus d’un an pendant l’Occupation, la base sous-marine de Bordeaux cristallise encore les souvenirs douloureux des heures sombres du Port de la Lune. Le bunker attire pourtant depuis les années 1960 des artistes, cinéastes, plasticiens et musiciens fascinés par l’esprit du lieu. Institutionnalisée au début des années 1990, la base sous-marine devient un espace dédié au nautisme avant d’être consacrée à l’art contemporain au début du XXIe siècle. Aujourd’hui au cœur du projet d’aménagement des bassins à flot du quartier de Bacalan, la base sous-marine questionne et intrigue ses visiteurs sur son passé, mais aussi – et surtout – sur son avenir.Build during the German occupation, the submarine base of Bordeaux active during hardly more than a year still crystallizes the painful memories of the dark hours of the « Port de la Lune ». Nevertheless, the bunker attracts artists, film-makers, visual artists and musicians fascinated by the spirit of the place since the 1960’s. Institutionalized at the beginning of 1990’s, the submarine base became a space dedicated to the yachting before contemporary art at the beginning of the XXIth century. Nowadays at the heart of the project of redevelopment of the wet docks in the urban area of Bacalan, the submarine base questions and intrigues its visitors on its past, but also – and especially – on its future.

  13. Le sous-titrage : une pratique à la marge de la traduction

    Directory of Open Access Journals (Sweden)

    Dumas, Louise

    2014-12-01

    Full Text Available Le sous-titre interlinguistique est un objet difficile à appréhender théoriquement. S'il permet d'aller d'une langue à une autre, il implique aussi un passage de l'écoute à la lecture et du cinéma à l'écriture. Le caractère interlinguistique est souvent mis en avant pour amener à considérer le sous-titrage comme une traduction. Sa complexité médiologique suggère toutefois qu'il est plus qu'une traduction. En même temps, les fortes contraintes (exigence de brièveté, de lisibilité, de cohérence avec l'image cinématographique auxquelles il est soumis font qu'il est moins qu'une traduction – moins exact, moins long, moins « équivalent » au texte original. Le présent travail se propose de réfléchir de manière théorique aux rapports entre sous-titrage et traduction. Pour ce faire, nous confronterons le sous-titrage aux concepts fondamentaux de la traductologie. Premièrement, le passage de l'oral à l'écrit opéré dans les sous-titres est intimement lié à la distinction traductologique entre traduction et interprétariat. Pour pouvoir condenser les dialogues, résumer leur contenu, le sous-titreur est amené à les interpréter, ce qui permet de souligner l'étroite parenté entre traduction, interprétariat et interprétation. Deuxièmement, les fortes contraintes auxquelles sont soumis les sous-titres invitent à s'interroger sur la notion d'équivalence qui se trouve normalement au principe de toute traduction. Toutes les théories traductologiques insistent sur le fait qu'une équivalence n'est jamais parfaite et que le traducteur privilégie certains niveaux d'équivalence : en poussant à l'extrême cette dynamique de sélection constitutive de l'équivalence, on peut considérer que les sous-titres sont équivalents aux dialogues. En tant que cas limite, le sous-titrage permet de tester les concepts fondamentaux de la traductologie et de définir leurs limites.

    1997-01-01

    Pourquoi l'Univers plutôt que le vide ? Le temps et l'espace existent-ils en l'absence de l'Univers ? Que reste-t-il quand tout est enlevé ? Pourquoi quelque chose plutôt que rien ? Depuis des siècles, ces interrogations mobilisent philosophes et physiciens. Mais aujourd'hui, le vide n'est pas le rien. Il serait même l'acteur central de l'histoire de la matière et de l'Univers, le partenaire privilégié de la physique. Vide et matière ne sont plus deux manifestations séparées de la nature, mais deux aspects d'une même réalité. Le vide est l'état de base dont la matière émerge, sans couper son cordon ombilical Le vide comme Univers du rien cède la place au vide comme Univers du tout. Que le vide puisse être conçu par les physiciens comme réservoir potentiel d'univers, voici qui ne devrait laisser personne indifférent. Ce livre ouvre un débat et nous convie à une réflexion surprenante.

    Stohr, J A; Briola, J [Commissariat a l' Energie Atomique, Saclay (France). Centre d' Etudes Nucleaires

    1958-07-01

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

    The geothermal plant of Clichy-sous-Bois has been operating for 2 years and covers the needs of 3,400 equivalent-dwellings, including a sport-hall, 2 schools, the town-hall and 7 low-cost groups of flats. Geothermal energy covers 65% of the energy yearly global consumption for heating and sanitary hot water, i.e. 35,151 MWh. Thus, 3,195 TOE are saved each year. In December, 1979, the town of Clichy-sous-bois delegated their sponsorship to the Societe d'equipement et d'amenagement du territoire du departement de la Seine-Saint-Denis - SODETAT 93 for the realization of the geothermal operation. The production and injection wells were drilled between July and September, 1981. The Dogger aquifer was encountered at 1,800 m deep, with a temperature of 70,8/sup 0/C and an exploitation yield of 200m/sup 3//h. Surface works started in March 1982 and were completed in November of the same year. Apart from the geothermal power plant, the network comprises 11 exchange substations and a distribution network of 2,700 m long with 7,000 m of underground pipes. This plant is exploited by the Compagnie francaise d'exploitation thermique (COFRETH) within the framework of a farmout contract for 20 years, including: production, transportation and public distribution of geothermal heat all over the city of Clichy-sous-Bois.

    Turner, B E; Larick, D K

    1996-08-01

    The influences of brine composition, internal temperature, heating rate, and storage periods up to 28 d on flavor, texture, and color of sous vide processed chicken breast were evaluated. Pectoralis major muscles containing water and sodium chloride, with or without sodium lactate, were browned and vacuum packaged. Sous vide processing was by fast or slow heating to an internal temperature of 77 or 94 C. Product was evaluated after 0, 14, and 28 d storage at 4 C. Quality was evaluated by gas chromatographic analyses of flavor volatiles, shear, color, and sensory panels. Incorporation of sodium lactate into brine did not influence oxidative stability (as measured by headspace gas chromatography) or sensory warmed-over flavor. Presence of sodium lactate did result in enhanced fresh roasted or meaty and saltiness sensory scores as well as a more yellow color. The more rapid heating rate decreased sulfur-containing compounds and did not influence other volatile concentrations. Products processed to 94 C were less juicy, less tender, and contained higher quantities of alcohols and hydrocarbons than those processed to 77 C. Storage resulted in a decline in fresh roasted or meaty flavor note and an increase in warmed-over flavor note and quantities of alcohols, aldehydes and ketones, hydrocarbons, and total headspace volatiles.

    Full Text Available The objective of this study was to evaluate the microbiological, physical and physico-chemical quality parameters of sous vide preparation of pen-reared tambaqui (Colossoma macropomum. To prepare the tambaqui sous vide, 200 g of fillet, 50 g of basil sauce (1:4 fish fillet:sauce ratio and 10 mL of 5% sodium lactate were used. The product was then vacuum-packaged, pasteurized at 65 ºC for 12.5 min and refrigerated. The presence of Salmonella spp., sulfite-reducing Clostridium and Listeria monocytogenes was not detected in the samples analyzed. The coliform count at 45 ºC and coagulase-positive staphylococci were below the limit (103 permitted by the law in vigor. Water retention capacity and chloride content analyses revealed that the tambaqui fillet differed significantly (P<0.05 from the sous vide because of the addition of basil sauce. The total volatile basic nitrogen (TVB-N and thiobarbituric acid reactive substances (TBARS content of the fillet and sous vide were below the limits established by the law, indicating good quality. The lightness (L* and yellow color (b* of the fillet and the sous vide did not differ significantly (P>0.05, but the red color (a* decreased in the sous vide, which is related to the addition of basil sauce. The chroma (C* and hue angle (ho differed significantly (P<0.05, and the fillet samples were lighter in color, whereas the sous vide was characterized by yellow color. The n-6/n-3 ratios found for the fillet and the sous vide are within the recommended values, which is important for human metabolism. The fillet and sous vide also had high calcium, zinc, magnesium and potassium concentrations. It is concluded that tambaqui sous vide is a good source of nutrients, rich in fatty acids and minerals essential for human health.

Il survient généralement chez le nourrisson et l'enfant. Cette tumeur touche dans la majorité des cas les tissus sous-cutanés des extrémités et du tronc. Elle est extrèmement rare au niveau de la tète et du cou. Un total de moins de 100 cas a été rapporté précédemment dans la littérature. PMID:25918563

    Full Text Available Dans ses deux premiers films, Rabah Ameur-Zaïmeche interprète un personnage qui, ayant écopé de la « double peine », finit par perdre sa place dans un aller et retour sans issue, entre son village algérien d’origine qui le rejette (Bled number One et la France qui l’expulse puis le traque à son retour (Wesh wesh qu’est-ce qui se passe ?. À ce destin qui s’avère borné par la folie, d’un côté de la Méditerranée, ou par la mort de l’autre, le cinéaste oppose la créativité de ses propres collectifs de production, dont il laisse volontairement des traces dans chacun de ses films. Il entend ainsi, malgré tout, réinvestir, par le désir de groupe, le champ du politique, et par l’invention de formes cinématographiques, ne pas exclure le spectateur d’un sentiment de solidarité et de fraternité désancré de ses bases strictement communautaires. Adossé à la réalité vécue par une génération issue de l’immigration algérienne, née ou ayant grandi en France après l’indépendance de l’Algérie, le cinéma de Rabah Ameur-Zaimèche évoque les ambivalences de l’expérience groupale de ceux qui vont et viennent avec constance et intensité d’une rive à l’autre de leurs désirs d’appartenance et d’engagement.  In his two first movies, Rabah Ameur-Zaïmeche plays a character who, subject to legal “double jeopardy”, finds himself lost in an inescapable back and forth between his native Algerian village, which rejects him, (Bled number One and France, which expels him and then, upon his return, hunts him down (Wesh wesh qu’est-ce qui se passe ?. Against this fate, which ends in madness on one side of the Mediterranean or death on the other, Rabah Ameur-Zaïmeche sets the creativity of his production teams, traces of whose work remains in each of his films. Despite everything, the filmmaker looks to reinvest the political field with collective desire, and, through the use of inventive cinematic

(author) [French] L'exploration des espaces sous-arachnoiediens pericerebraux par les radioisotopes (cisternographie radioisotopique ou 'RISA- cisternography' ) prend une place de plus en plus importante parmi les techniques neuroradioisotopiques de diagnostic. Elle fournit de precieux renseignements sur la permeabilite des espaces sous-arachnoiediens et sur la dynamique du liquide cephalo-rachidien (LCR). On doit actuellement la considerer comme indispensable et irremplacable dans le diagnostic de certaines affections neurologiques, tout comme la gamma-encephalographie et les techniques neuroradiologiques plus classiques (angiographie et pneumographie cerebrales). En effet, cet examen est seul a preciser l'aspect morphologique global des espaces sous-arachnoiediens pericerebraux; tout en renseignant sur la permeabilite des citernes pericerebrales et des sillons de la convexite, il fournit une image scintigraphique typique et symetrique, facile a observer, de face et de profil, des voies principales de circulation du LCR cisternal. L'image scintigraphique d'une citerne indique qu'elle est permeable et que l'espace sous-jacent l'est aussi. Du point de vue dynamique, la cisternographie radioisotopique, outre la demonstration par voie scintigraphique de la permeabilite des citernes, met en evidence le schema normal ou pathologique de la dynamique du LCR. Le schema normal de progression du LCR est actuellement bien etabli.

Outre des différences qui tiennent bien évidemment à la singularité de chacun, on peut repérer entre ces deux auteurs des attitudes et préoccupations semblables. Tous deux, blessés, et Cendrars, mutilé de sa main droite, celle de l’écrivain, ont éprouvé cette expérience de guerre comme épreuve initiatique menant à l’affirmation de leur singularité au sein du Nous de la communauté. Tous deux ont fait du souvenir de leurs camarades morts leur tâche poétique. Tous deux ont reconnu la réalité de ce que Graves, jusqu’à la fin de sa vie, nomma « meurtre » – et Cendras écrivit « J’ai tué ».L’expérience de guerre a suscité chez ces deux poètes un refus du dualisme idéaliste (« Il n’y a pas d’absolu, » écrit Cendrars. « Il n’y a donc pas de vérité, sinon la vie absurde qui remue ses oreilles d’âne. », un rejet de l’exaltation de la virilité, marque de la période de l’entre-deux guerres, comme l’a montré G.L.

    BACKGROUND: Although research into the continuity and change of personality traits during a lifespan has been fairly extensive, little research has been conducted on childhood predictors of adult personality. PURPOSE: We aimed to investigate the association between infant socioeconomic status (SES......), and Eysenck personality traits in adulthood.

    eclaircis, nous pensons avoir assez de resultats concordants concernant la polymerisation du sous-oxyde de carbone pour pouvoir conclure en faveur d'un mecanisme ionique. Quant a la formule elle doit tres vraisemblablement comporter des enchainements de cycles lactoniques pour des raisons deja invoquees par d'autrus auteurs; mais l'examen du spectre infrarouge du polymere anhydre montre qu'il s'agit plutot de doubles cycles condenses pentagonaux, relies entre eux par des liaisons simples ou doubles selon la disposition des doubles liaisons a l'interieur des cycles. Recapitulons ci-dessous les principaux resultats en faveur d'un mecanisme ionique, ainsi que les objections qu'il est possible de leur opposer le cas echeant: 1 - Les capteurs de radicaux libres, NO, O{sub 2} ou CH{sub 3} - CH = CH{sub 3} ne modifient pas la vitesse de polymerisation thermique ou sous rayonnement. Ces gaz se retrouvant inchanges a la fin de la polymerisation. 2 - L'acetaldehyde a effectivement une action inhibitrice mais celle-ci n'est vraisemblablement pas de nature radicalaire car si on fait agir l'acetaldehyde sur un film de polymere anhydre et qu'on l'evacue ensuite le film n'a pas perdu ses proprietes catalytiques vis-a-vis d'une 'seconde' polymerisation (pas de periode d'induction), en outre nous avons constate que l'acetaldehyde ne supprimait pas le paramagnetisme du polymere. Nous avons deja interprete l'action inhibitrice de l'acetaldehyde comme etant due a une adsorption preferentielle, bien que nous n'ayons pas mesure directement cette adsorption. 3 - BF{sub 3} initie la polynerisation de C{sub 3}O{sub 2} en phase liquide, a basse temperature, et le polymere qu'on obtient de cette facon est paramagnetique, 4 - Inversement on a constate l'echec d'un essai d'initiation de la polymerisation pour un generateur de radicaux libres. 5 - L'action de l'eau montre que le paramagnetisme du polymere n'est pas du a des radicaux libres mais a la chaine de doubles liaisons conjuguees.

  8. Composes inter-halogenes sous pression: etude des transformations structurales dans le monobromure d'iode sous forme dense

    Bouchard, Alexandre

    La famille des composes halogenes et inter-halogenes representent des solides moleculaires adoptant des phases denses communes avec des solides moleculaires diatomiques comme l'azote et l'hydrogene. Parmi les transformations structurales et electroniques induites sous haute pression et observees dans ces solides, on note, entre autres, la dissociation moleculaire et la metallisation. De plus, l'etude des phases denses de l'iode a permis recemment l'observation d'une structure cristalline possedant une modulation dite incommensurable, c'est-a-dire une modulation possedant une periodicite differente de celle de la structure cristalline, jetant ainsi une lumiere nouvelle sur le processus de dissociation moleculaire dans les solides halogenes. Dans ce memoire, on propose d'etudier les changements structuraux dans monobromure d'iode (IBr), un compose inter-halogene possedant des proprietes structurales semblables a celles de deux composes halogenes, soit l'iode (I 2) et le brome (Br2) sous leur forme solide. Des experiences de diffraction des rayons X de poudres en utilisant un rayonnement synchrotron ont ete realisees a temperature ambiante sur l'IBr en variant la pression jusqu'aux environs de 60 GPa. La nature chimique particuliere du compose IBr a necessite la mise au point de techniques de chargement d'echantillon destinees a preserver l'integrite chimique de la substance utilisee. On rapporte egalement l'observation d'une phase de l'IBr presentant une modulation incommensurable. Les phases observees dans l'IBr permettent d'etablir des paralleles avec les phases denses rapportees dans I2 et Br2 par le biais d'un modele phenomenologique decrivant la sequence structurale des solides halogenes sous forme condensee.

    Le lien entre harcèlement et emprise professionnelle est bien réel. Il est aussi puissant que destructeur. L'aide extérieure est importante mais la prise de conscience du sujet et sa mise à distance sont primordiales pour le retour à Soi. Un facteur de risque organisationnel est un facteur qui relève de l'organisation et qui comporte le risque ou la probabilité qu'un tel comportement abusif voie le jour et qu'il ait des effets négatifs. Un tel facteur peut également contribuer à la persistance ou à l'aggravation du comportement. En abordant la relation d'emprise sous l'éclairage de différentes théories psychologiques, cela vous permettra d'observer les mécanismes intrapsychiques conscients et inconscients qui sous-tendent les comportements de l'instigateur de la relation d'emprise d'une part, et de sa victime d'autre part.

    Full Text Available Tournant le dos aux interprétations nationalistes indiennes et pakistanaises, cet article restitue la dimension millénariste de la carrière de Sayyid Ahmad Barelwî (1786-1831. Ce soufi naqshbandi, qui fut successivement soldat de fortune et réformateur religieux, lança en 1826 un jihâd contre les Sikhs et contre la présence britannique en Inde. Il disparut mystérieusement lors d'une bataille, et ses disciples attendirent son retour comme mahdi pendant plus d'un demi-siècle. Cette ultime arrière messianique est interprétée en quatre étapes. Je montre d'abord comment le contexte politique et social favorisait le développement d'idées millénaristes. La mentalité religieuse de l'époque et la place qu'y occupait l'eschatologie sont ensuite étudiées. La carrière posthume de Sayyid Ahmad comme mahdi est ensuite restituée à travers les sources coloniales. Enfin l'examen de documents originaux en persan écrit avant la mort de Sayyid Ahmad corrigera cette image coloniale, tout en montrant que, déjà de son vivant, il était bien perçu par ses disciples comme une sorte de mahdi du milieu des temps, analogue à certains égards au mujaddid tek que le concevaient les Naqshbandis.

    Full Text Available Vers 1770, la campagne anti-russe du gouvernement français tend à dégrader l’image de la Russie, ce qui lèse gravement ses intérêts, notamment quand elle doit emprunter pour financer la guerre avec la Turquie. Aussi le prince Dmitri Alexeevitch Golitsyn, ministre plénipotentiaire à La Haye, se montre-t-il alors très actif sur ce terrain. Sa correspondance avec Pétersbourg témoigne de ses efforts, aux effets inégaux, pour influer sur les informations diffusées par quelques journaux : principalement le Courrier du Bas-Rhin, publié par Jean Manzon à Trèves, sous contrôle prussien, et dans une moindre mesure les deux Gazettes des Deux-Ponts, l’une politique, l’autre littéraire. Le journaliste de Trèves, qui trouve son intérêt à prendre le parti de la Russie, met en œuvre en sa faveur un discours journalistique abondant et parfois très élaboré. Cependant, la ligne du journal subit des fluctuations sensibles, selon l’évolution de la situation et à la suite de diverses interventions, dont celles du roi de Prusse et d’autre part de Stanislas-Auguste, qui pensionne un temps le journaliste. La Gazette des deux Ponts pratique l’information orientée avec plus de finesse, et, comme la gazette littéraire, accorde une large place à la matière russe : mais sur le plan politique, son traitement reste le plus souvent sous influence française et répond rarement aux vœux de D. A. Golitsyn.

    This study was performed to investigate the changes in meat quality characteristics of the sous vide cooked chicken breast during refrigerated storage at 4℃ for 14 d between before and after sous-vide cooking. Cooking loss and shear force were significantly increased, whereas expressible drip was significantly decreased along with reduction in the water holding capacity in both of two groups. Redness of meat juice was significantly (p<0.05) increased during storage, and considerably increased in the refrigerated samples after sous-vide cooked at the 7 to 10 d. The thiobarbituric acid reactive substances (TBARS) was significantly increased and was higher in the refrigerator stored chicken breast samples after sous-vide cooking. The volatile basic nitrogen (VBN) value was significantly increased in both groups, but the VBN value of the stored raw meat sample before sous-vide cooking was increased at an early storage, while the VBN value of the stored sample after sous-vide cooking was increased gradually in this study. Total viable counts and coliform counts were significantly decreased during storage, and coliforms were not detected after 7 d of storage in both groups. Salmonella spp. was not detected during the whole studied period. The outcome of this research can provide preliminary data that could be used to apply for further study of chicken breast using sous-vide cooking method that could be attractive to consumers.

    Full Text Available Dans le septième et dernier tableau de La Tentation de saint Antoine de 1874, la fin célèbre est mise en contexte par une description longue et détaillée qui n’a jamais attiré l’attention critique qu’elle mérite. Cet article analyse l’importance de ce panorama du monde naturel sous la forme d’une exploration intertextuelle des passages du Cosmos d’Alexandre de Humboldt. Que Flaubert signale ses lectures de l’œuvre de Humboldt dans sa Correspondance de 1860 suggère des liens très riches entre Le Cosmos – que Humboldt désigne comme « l’œuvre de ma vie » – et la Tentation de saint Antoine définitive que Flaubert retravaillait au même moment. Cette relecture de La Tentation à travers la perspective de Humboldt souligne la place importante du Cosmos parmi les découvertes et les textes scientifiques contemporains de Flaubert, et la manière dont ceux-ci informent la vision de la vie scientifique et religieuse de son protagoniste, Antoine.In the seventh and final tableau of the Tentation de Saint Antoine of 1874, the famous finale is set in the context of a long, detailed description which has not attracted the critical attention it deserves. This article focuses on the importance of this panorama of the natural world as an intertextual exploration of passages from Kosmos by Alexander von Humboldt. The fact that Flaubert’s Correspondance of 1860 mentions his reading of Humboldt’s works suggests rich lines of investigation between Kosmos – which Humboldt calls the « work of all of life » and the final Tentation de Saint Antoine,which Flaubert was reworking at the same moment. This re-reading of the Tentation through the optic of Humboldt underscores the pivotal position of Kosmos amid the scientific discoveries and texts contemporary to Flaubert, and how these inform the vision of life of his protagonist, Antoine, as scientific and religious.

    1996-01-01

    A European coordinated research program for the study of hot-dry-rock systems is in progress at Soultz-sous-Forets (Alsace, France). The aim of this project is the extraction of heat from the granite batholiths distributed along the Rhine graben. The technique used involves important forced water circulations under relatively low-pressures using the natural geologic fractures network. The region concerned extends about 3000 km 2 under both the French and the German territories. The program started in 1987 with preliminary scientific investigations followed by a feasibility study. In December 1995, two deep wells, GPK1 (3600 m) and GPK2 (3900 m) were available and equipped for hydraulic testing. Temperatures encountered can reach 168 C at 3800 m with a geothermal gradient exceeding 3.5 C/100 m below 3600 m. The tests performed have shown that the hydraulic performances of these wells can be considerably improved using a simple well stimulation technique. (J.S.). 1 fig

  5. A SES (sustainable energy security) index for developing countries

    International Nuclear Information System (INIS)

    Narula, Kapil; Reddy, B. Sudhakara

    2016-01-01

    Measuring the performance of the energy system of a country is a prerequisite for framing good energy polices. However, the existing indices which claim to measure energy security have limited applicability for developing countries. Energy sustainability is also increasingly gaining importance and countries are keen to measure it to tailor their energy policies. Therefore, the concept of SES (sustainable energy security) has been proposed as the goal for a developing country. This paper presents an analytical framework for the assessment of SES of an energy system and the methodology for constructing an SES index. A hierarchical structure has been proposed and the energy system has been divided into 'supply', 'conversion & distribution' and 'demand' sub-systems. Each subsystem is further divided into its components which are evaluated for four dimensions of SES, Availability, Affordability, Efficiency and (Environmental) Acceptability using quantitative metrics. Energy indices are constructed using 'scores' (objective values), and 'weights' (subjective values representing tradeoffs) which are then aggregated, bottom-up, to obtain an overall SES Index for a country. The proposed SES Index is multidimensional, quantitative, modular, systemic and flexible. Such a SES Index can be used to design policy interventions for transitioning to a sustainable and a secure energy future. - Highlights: • A SES (sustainable energy security) index is proposed for developing countries. • A hierarchical structure includes the entire energy system from supply to end use. • The performance of all energy sources, energy carriers and sectors is assessed. • Availability, affordability, efficiency and acceptability dimensions are evaluated. • The SES index is multidimensional, quantitative, modular, systemic and flexible.

    The realization of an Van de Graaff accelerator required, for the preliminary studies, the construction of a small proton accelerator, functioning at 200 kV in order to resolve some parasitic effects inherent to the accelerators tubes. The aim of this report is to describe the different organs of the accelerator tube, to explain the operating system and to encode their characteristics. The report first presents the ion source and the beam buncher permitting to inject in the accelerator tube particles of about 9 kV and very batched in a thin beam of circular section. Then the study explain the tube characteristics considered like optic system. A method to obtain precise calculation of particle trajectories is exposed. Aberrations of the system were discussed and balance of the currents on all electrodes inside the tube for different regimes of working were provided. The influence of the residual pressure in the tube were explained. The report finally ends on a part of the fundamental problem of the straining occurring inside the tubes accelerators under high tension. (M.B.)

  7. Irradiation damage 'displacement zone'; Dommages sous irradiation zone de deplacements

    It is well known that a charged particle (ion, primary atom, etc...) moving in a solid slows down and can cause a cascade of displacements of the atoms in the solid. A study is made here of the extent to which the cascade is made up, or not, of independent collisions, as a function of the energy of the initial charged particle. When the distance between the collisions is small, these latter are no longer independent; the cascade, which then has to be considered as a whole, perturbs and locates, in the irradiated solid , a zone which has been named a 'displacement zone'. It is shown that the proportion of displacement zones increases with increasing atom size (high atomic number Z), with decreasing atomic distance D in the substance considered and with decreasing energy of the ion undergoing the slowing down process (although always remaining above a few hundred eV). The proportions obtained are higher than those corresponding to the calculations of J. A. Brinkman [3]. An interatomic potential required for this work has also been determined. (author) [French] On sait qu'une particule chargee (ions, atomes primaires, etc...) en mouvement dans un solide se ralentit, avec eventuellement deplacement en cascade d'atomes du solide. On etudie ici dans quelle proportion, en fonction de l'energie de la particule chargee initiale, la cascade est constituee, ou non, de 'chocs independants'. Lorsque la distance entre chocs est petite, ceux-ci ne sont plus independants; la cascade, qui doit alors etre consideree dans son ensemble, perturbe et definit dans le solide irradie, une zone qu'on a appele zone de deplacements. On montre que la proportion de zones de deplacements est d'autant plus grande que les atomes sont gros (nombre atomique Z grand), que la distance interatomique D est petite dans le corps considere, et que l'energie de l'ion en ralentissement est petite (tout en restant superieure a quelques centaines d'eV). Les proportions obtenues sont superieures a celles qui

    The method proposed is designed for the study of neutronic properties of a sample (its material buckling, for example) and consists in submitting the sample to uniform surface density irradiation, its surface being a sphere or a cylinder which is supposed, temporarily, to be infinite. Neutron density in the sample will thus be uniform if its laplacian is nil: any curve in the distribution clearly indicating its absorbent or multiplying properties. In the case of a sample with multiplying power, density is identical to that in an active core, thus measurement of buckling will be free from considerable systematic error causes. The thermic equivalent of this type of irradiation would be a thermostat with an external heat source distributed uniformly over its surface: its temperature would be uniform. It is this analogy that has led us to baptize it the 'Neutrostat'. (author)Fren. [French] En vue d'etudier les proprietes neutroniques d'un milieu (son laplacien 'matiere' par exemple), la methode proposee consiste a le soumettre a des conditions d'irradiation uniforme sur sa surface, celle-ci ayant la forme d'une sphere ou d'un cylindre que nous supposons provisoirement infini. Les neutrons s'y trouvent alors repartis avec une densite uniforme si le milieu est un diffuseur pur. Toute courbure de cette repartition sera un indice sensible de ses proprietes absorbantes ou multiplicatrices. Dans le cas d'un milieu multiplicateur, la repartition est identique a celle qui regne au milieu d'une pile critique et nous verrons que la mesure du laplacien est alors exempte de causes d'erreurs systematiques importantes. L'equivalent thermique d'un tel mode d'irradiation serait un dispositif thermostatique dont la source de chaleur externe serait repartie uniformement sur la surface: il y regnerait une temperature uniforme. C'est cette analogie qui nous a guides dans le choix du vocable propose dans le titre: 'Neutrostat'. (auteur)

    The present study embarked on the objective of optimizing improved sous - vide processing condition for development of ready-to-cook Pangasius steaks with extended shelf-life using response surface methodology. For the development of improved sous - vide cooked product, Pangasius steaks were treated with additional hurdles in various combinations for optimization. Based on the study, suitable combination of chitosan and spices was selected which enhanced antimicrobial and oxidative stability of the product. The Box-Behnken experimental design with 15 trials per model was adopted for designing the experiment to know the effect of independent variables, namely chitosan concentration (X 1 ), cooking time (X 2 ) and cooking temperature (X 3 ) on dependent variable i.e. TBARS value (Y 1 ). From RSM generated model, the optimum condition for sous - vide processing of Pangasius steaks were 1.08% chitosan concentration, 70.93 °C of cooking temperature and 16.48 min for cooking time and predicted minimum value of multiple response optimal condition was Y = 0.855 mg MDA/Kg of fish. The high correlation coefficient (R 2  = 0.975) between the model and the experimental data showed that the model was able to efficiently predict processing condition for development of sous - vide processed Pangasius steaks. This research may help the processing industries and Pangasius fish farmer as it provides an alternative low cost technology for the proper utilization of Pangasius .

These installations are sub-critical with multiplication factors (k{sub eff}) for total reflection of 0.73 and 0.77. A third evaporator of 200 litres, also sub-critical (k{sub eff} = 0.90), is given as the limiting possible case. A description is also given of simple devices without regulator for maintaining a constant level in an extra flat, separator thus making it possible to operate without supervision in perfect safety at any concentration factor. The liberal thermal characteristics and the simple operational principles constitute a sure guarantee for operation in {alpha} and {gamma} conditions.

    Full Text Available L’environnement chimique de l’ADN en situation biologique est complexe notam-ment en raison de la présence d’histones, protéines nucléaires, associées en quantité approximativement égales à l’ADN pour former la chromatine. Les histones possèdent de nombreux radicaux basiques arginine et lysine chargés positivement et dont la majorité se trouve sur les chaînes émergentes, l’ADN présente quant à lui des charges négatives sur ses groupements phosphates localisés tout au long de la double hélice. Dans cette étude, la complexité de la structure de la chromatine nucléaire est dans un premier temps mimée en solution aqueuse par la formation de complexes entre un ADN plasmidique sonde et les trois acides aminés basiques, Arg, His, Lys, qui, mis à part His, sont protonés au pH physiologique. Ces acides aminés libres en solution sont réputés être des capteurs efficaces de radicaux libres, notamment pour le radical hydroxyle, conférant ainsi un pouvoir protecteur vis-à-vis des effets indirects sur l’ADN en situation d’exposition aux rayonnements ionisants. A concentration fixée, les capacités de capture des acides aminés libres, σ, pour le radical hydroxyle sont typiquement les suivantes σHis ≈σArg > σLys (σLys ≈ 0,1 × σArg.

    2016-01-01

    Socioeconomic status (SES) is a complex construct of multiple indicators, known to impact cancer outcomes, but has not been adequately examined among pediatric AML patients. This study aimed to identify the patterns of co-occurrence of multiple community-level SES indicators and to explore associations between various patterns of these indicators and pediatric AML mortality risk. A nationally representative US sample of 3,651 pediatric AML patients, aged 0–19 years at diagnosis was drawn from 17 Surveillance, Epidemiology, and End Results (SEER) database registries created between 1973 and 2012. Factor analysis, cluster analysis, stratified univariable and multivariable Cox proportional hazards models were used. Four SES factors accounting for 87% of the variance in SES indicators were identified: F1) economic/educational disadvantage, less immigration; F2) immigration-related features (foreign-born, language-isolation, crowding), less mobility F3) housing instability; and, F4) absence of moving. F1 and F3 showed elevated risk of mortality, adjusted hazards ratios (aHR) (95% CI): 1.07(1.02–1.12) and 1.05(1.00–1.10), respectively. Seven SES-defined cluster groups were identified. Cluster 1: (low economic/educational disadvantage, few immigration-related features, and residential-stability) showed the minimum risk of mortality. Compared to Cluster 1, Cluster 3: (high economic/educational disadvantage, high-mobility) and Cluster 6: (moderately-high economic/educational disadvantages, housing-instability and immigration-related features) exhibited substantially greater risk of mortality, aHR(95% CI) = 1.19(1.0–1.4) and 1.23 (1.1–1.5), respectively. Factors of correlated SES-indicators and their pattern-based groups demonstrated differential risks in the pediatric AML mortality indicating the need of special public-health attention in areas with economic-educational disadvantages, housing-instability and immigration-related features.

    1991-03-01

    The SES-10 units are unpressurized, pool-type nuclear reactors of 10MW rating, designed for supplying energy to hot water district heating systems, economically and without pollution. Water for heat distribution is brought to a maximum temperature of 85 degrees C. Conventional heating units supplement the output from SES-10 units for peak load and during maintenance. The SES-10 is housed in a low-cost building, with a double-walled pool in the ground. A naturally circulating primary system and a pumped secondary system transport heat from the reactor to the distribution system. The unit is fully automated and easy to maintain. Because of the many active and passive safety features, it is feasible to license the SES-10 for operation in a city and easy to explain it to the public for their acceptance. The core lasts approximately 43 months at a capacity factor of 70%, and the cost of heat is expected to be 2 to 2.5 cents/kWh

    Le mal de Pott est la forme la plus commune de la tuberculose osseuse touchant essentiellement le rachis dorso-lombaire. La localisation sous-occipitale reste exceptionnelle. Le diagnostic de cette entité est le plus souvent tardif ce qui expose à des complications graves. Les radiographies standard ne sont parlantes qu’à un stade tardif de la maladie, d'où l'intérêt de l'imagerie moderne notamment la tomodensitométrie (TDM) et l'imagerie par résonance magnétique (IRM) qui permettent un diagnostic précoce. Nous rapportons un nouveau cas de tuberculose sous-occipitale. Le diagnostic était posé sur l'imagerie en coupe et confirmé histologiquement à la biopsie transorale. Sont rappelés les aspects en imagerie de cette localisation particulière du mal de Pott. PMID:23819005

    Lamb loins were subjected to sous-vide cooking at different combinations of temperature (60 and 80°C) and time (6 and 24h) to assess the effect on the volatile compound profile. Major chemical families in cooked samples were aliphatic hydrocarbons and aldehydes. The volatile compound profile in sous-vide cooked lamb loin was affected by the cooking temperature and time. Volatile compounds arising from lipid oxidation presented a high abundance in samples cooked at low or moderate cooking conditions (60°C for 6 and 24h, 80°C for 6h), while a more intense time and temperature combination (80°C for 24h) resulted on a higher concentration of volatile compounds arising from Strecker degradations of amino acids, as 2-methylpropanal and 3-methylbutanal. Therefore, sous-vide cooking at moderately high temperatures for long times would result in the formation of a stronger meaty flavor and roast notes in lamb meat. Copyright © 2014 Elsevier Ltd.

    The combined effects of radiation and sous-vide treatment of chicken breast meat were investigated with respect to survival and growth of Listeria monocytogenes, shelf life, thiamine content, and sensory qualities. Chicken breasts were inoculated with L. monocytogenes 81-861 (10(5) CFU/G), vacuum-packed, irradiated with electron beam (EB) up to 2.9 kGy, and cooked to an internal temperature of 65.6 degrees C. Sous-vide treatment alone had marginal lethal effect on the L. monocytogenes; the residual inoculum reached 10(7) CFU/g after 8 weeks at 2 degrees C. However, after the combined treatments of sous-vide and EB at 2.9 kGy, the organism remained undetectable during the 8-week storage period. Parallel studies on uninoculated breast meat revealed that sous-vide samples had a shelf life of less than 6 weeks without EB treatment, whereas samples that were irradiated and then received sous-vide treatment had a shelf life of at least 8 weeks. There was a slight reduction in thiamine levels as a result of the EB treatment, but there was essentially no additional loss of thiamine due to the subsequent sous-vide treatment and storage at 2 degrees C. Electron-beam treatment had very little effect on the odor and flavor of the reheated samples. It was concluded that EB treatment combined with, sous-vide treatment can greatly enhance the microbial safety and shelf life of chicken breast meat

Il est l'incarnation même de l'artiste au cœur de son peuple, lui qui s'est imposé dans le champ artistique avec son talent, son franc-parler, sa musique et sa poésie. Son parcours ne peut être dissocié de ses engagements politiques. Il combat les fondamentalistes islamistes et s'oppose au pouvoir en place. Il veut la reconnaissance du berbère, sa langue maternelle et celle de ses chansons, par l’État algérien. Il porte un regard sur l’histoire en reprenant des mythes tout en révélant des vérités. Il brise également des tabous de la société mais reprend des poncifs. Ses chansons, dans lesquelles se reconnaissent des milliers de personnes, disent les contradictions d'un individu tourmenté. L'imaginaire de ses poèmes est régional et rural. En revanche, son désir tend vers la nation entière et même vers l'universel. La tragédie de sa vie est indissociable des durs contextes politiques qu'expriment ses paroles. Algerian poet, singer and songwriter Lounès Matoub became an icon after his assassination. In the hearts of his people, he is the embodiment of an artist, having established himself with his talent, his outspokenness, his music and his poetry. His career cannot be dissociated from his political commitments. He fights against the Islamic fundamentalists and rebels against the governing power. He wants Berber, his mother language and that of his songs, recognized by the Algerian government. He examines history by recycling myths while revealing truths. He breaks societal taboos but unravels clichés. His songs tell of the trials of a tormented individual, but thousands of people recognize themselves in his songs. The scope of his poems is regional and rural. However, his desire extends to the whole nation, even to the universal. The tragedy of his life is inseparable from the tough political context that his words describe.

    Language skills, strongly linked to academic success, are known to differ by socioeconomic status (SES), with lower SES individuals performing less well than higher SES. To examine the effect of SES on infant language at 7months of age and the relationship between maternal vocabulary skills and infant language function. To determine if the relationships between SES and infant language are mediated by maternal vocabulary skills. Longitudinal follow-up of healthy term female African American infants born to mothers in two SES groups: Low SES (income-to-needs≤1, no education beyond high school) and Higher SES (Income-to-Needs >1, at least a high school diploma). 54 infants tested at 7months of age; 54 mothers tested at infant age 7months. Preschool Language Scale-5 (PLS-5), Vocabulary and Matrix Reasoning subtests of the Wechsler Adult Intelligence Scale-IV. Low SES infants (n=29) performed less well than Higher SES (n=25) on PLS-5 Total Language, Auditory Comprehension, and Expressive Communication (p≤0.012). Maternal Vocabulary subtest scores were lower in Low SES than Higher SES (p=0.002), but not related to infant PLS Language scores (p≥0.17). Maternal vocabulary did not mediate the relationship between SES and infant language skills at age 7months. In this single sex and race cohort of healthy, term, female infants, lower SES exerted negative effects on infant language by 7months of age. While maternal vocabulary scores showed no relation with infant language skills at 7months, continued study of the relations between SES, infant outcomes and maternal characteristics is needed to determine how low SES conditions impact early language. These findings underscore the importance of early interventions, as well as policies designed to improve socioeconomic conditions for infants and families. Copyright © 2015 Elsevier Ireland Ltd.

    In this work, slices of Longissimus dorsi of pork was used as raw material to establish the effects of the sous-vide technology and the high hydrostatic pressure treatments (and their combinations) on meat. The state of the proteins in meat has a very important effect on several quality parameters of the product, such as weight loss, water holding capacity, organoleptic properties. Therefore it is important to follow and analyse the denaturation of the protein content during food processing. The samples were cooked sous-vide (60 °C, 5-480 minutes) or pressurized (100-600 MPa, 5 minutes, room temperature). Also two steps treatments were studied combining both technologies, applying high hydrostatic pressure treatment (300 or 600 MPa, 5 minutes, room temperature) after or previous to sous-vide cooking (60 °C, 30 minutes). The changes in the condition of meat proteins were followed by a differential scanning calorimeter. The DSC curves were analysed using the unit’s own software where denaturation heat was determined. Thermograms show through the change of the sample’s protein state the dissimilar effect of the treatments. Using the Polar Qualification System -previously proved to be effective with NIR measurements- the spectral information was reduced to a two dimensional polar co-ordinate system where each DSC curve is represented by a “quality point”. As a new experiment the applied PQS data reduction method compared to the traditional thermal analysis data processing gave us less information on the differences of our samples although the results are promising as we were able to detect the same trends and characteristics.

    Pressure or water level measurements have been performed by GTC in different wells at the geothermal testsite Soultz-sous-Forets for six years now. The water lever variations are mainly influenced by earth tides, barometric pressure variations, hydraulic testing and stimulation. The small scale variations are influenced by tidal and barometric forcing functions, the large scale variations by hydraulic testing and stimulation. By analyzing such measurements it is possible to get important information about the hydrualic connections between the boreholes, as well as aquifer parameters. (orig./AKF)

Co-découvreur des arts dits « primitives » dès 1916...... avec Guillaume Apollinaire, l’écrivain va les insérer dans son travail poétique comme miroirs inversés de la modernité occidentale. Cependant, même s'il utilise certains des clichés racistes de son époque, il se place lui-même dans le camp des « mélanophiles », et va se servir de cet Art Nègre pour...... repousser à l'extrême les frontières de la modernité.

    This study aims to shed light on the changes provoked by boiling, steaming and sous-vide cooking on the lipids and volatile profile of farmed and wild European sea bass meat. None of the cooking techniques provoked changes due to hydrolytic or oxidation processes detectable by 1 H NMR on sea bass lipids. The lipid profile of main and minor lipidic components was maintained after cooking. However, study by SPME-GC/MS evidenced that steaming and sous-vide cooking modified the volatile profile of sea bass meat, especially in farmed specimens. The compounds generated came from the occurrence, to a very small extent, of lipid and protein degradation. By contrast, boiling scarcely modified the initial characteristics of raw sea bass. Thus, from a sensory point of view and considering the odour-active compounds generated, steaming and sous-vide cooking provoked more noticeable changes than boiling, especially in farmed sea bass meat.

    Exposure to low socioeconomic status (SES) in childhood predicts increased morbidity and mortality. However, little prospective evidence is available to test pathways linking low childhood SES to adult health. In the current study, indirect effects through positive parenting in adolescence and adult SES were tested in the association between childhood SES and adult health behaviors and psychological resources. Men (n = 305; 53% Black) were followed longitudinally from ages 7 to 32. SES was measured annually in childhood (ages 7-9) and again in adulthood (age 32) using the Hollingshead index. Parenting was assessed annually (ages 13-16) using caregivers' and boys' self-report of supervision, communication, and expectations for their son's future. Health behaviors (cigarette and alcohol use, fruit and vegetable consumption, and physical activity) and psychological resources (optimism, purpose in life, self-mastery, and self-esteem) were assessed in adulthood (age 32). Structural equation modeling showed that higher childhood SES was associated with more positive parenting in adolescence and higher adult SES. Higher childhood SES was indirectly associated with healthier behaviors and higher psychological resources in adulthood through pathways involving positive parenting during adolescence and SES in adulthood. Findings were consistent in both racial groups. Positive parenting in adolescence was an important pathway in understanding associations among childhood SES and health behaviors and psychological resources in adulthood. Low childhood SES was prospectively associated with healthier behaviors and greater psychological resources in part through more positive parenting in adolescence.

    We have studied brazing in vacuum aiming its application for the making of containers and apparatus meant for high vacuum (p < 10{sup -8} torr). We first define the wettability of a brazing alloy on a metal and we remind the influence of the various parameters which act on this wettability (nature of the solid, of the liquid, geometrical and physicochemical state of the surface, metallurgical reactions occurring at the interface, temperature, time). We give then the results of the tests carried out in order to determine the conditions of wettability in vacuum of some brazing alloys on metals which can be used for the above mentioned apparatus (stainless steel, aluminium, bronze, titanium, zirconium, kovar, nickel, copper).

    2016-05-01

    This paper asks whether workers with higher socioeconomic status (SES) experience different levels of stress at work than workers with lower SES and, if so, what might explain these differences. We collected innovative assessments of immediate objective and subjective measures of stress at multiple time points across consecutive days from 122 employed men and women. We find that in comparison to higher SES individuals, those with lower SES reported greater happiness at work, less self-reported stress, and less perceived stress; cortisol, a biological marker of stress, was unrelated to SES. Worker's momentary perceptions of the workplace were predicted by SES, with higher SES individuals more commonly reporting feeling unable to meet work demands, fewer work resources, and less positive work appraisals. In turn, perceptions of the workplace had a generally consistent and robust effect on positive mood, subjective stress, and cortisol. Copyright © 2016 Elsevier Ltd. All rights reserved.

  1. Job Pressure and SES-contingent Buffering: Resource Reinforcement, Substitution, or the Stress of Higher Status?

    Science.gov (United States)

    Koltai, Jonathan; Schieman, Scott

    2015-06-01

    Analyses of the 2008 National Study of the Changing Workforce demonstrate that job pressure is associated with greater anxiety and job dissatisfaction. In this paper we ask, What conditions protect workers? The conventional buffering hypothesis in the Job-Demands Resource (JD-R) model predicts that job resources should attenuate the relationship. We test whether the conventional buffering hypothesis depends on socioeconomic status (SES). Support for conventional buffering is evident only for job dissatisfaction--and that generalizes across SES. When anxiety is assessed, however, we observe an SES contingency: Job resources attenuate the positive association between job pressure and anxiety among workers with lower SES, but exacerbate it among those with higher SES. We discuss the implications of this SES-contingent pattern for theoretical scenarios about "resource reinforcement," "resource substitution," and the "stress of higher status." Future research should consider SES indicators as potential contingencies in the relationship between job conditions and mental health. © American Sociological Association 2015.

    The processing of sous vide chicken sausages was optimized under vacuum packaging condition and cooking at 100 ℃ for 30 min (SV30), 60 min (SV60) and 120 min (SV120) and compared with aerobically cooked control at 100 ℃ for 30 min. Sous vide processing of chicken sausages (SV30) produced higher (p emulsion ultra-structure due to SV30 processing relative to control sausages. Sous vide processing of chicken sausages enriched with rosemary diterpene phenols retained the freshness and quality up to 120 days during storage at 4 ± 1 ℃ relative to control sausages that were spoiled on 20th day. Lipid oxidation and microbial growth remained below the spoilage levels for all the SV-processed sausages throughout the storage and addition of rosemary diterpene mixture at 0.02% v/w reduced the microbial growth and improved (p < 0.05) the sensory attributes. Our results demonstrate that sous vide processing minimizes lipid oxidation and microbial growth of chicken sausages with improved product quality and shelf-life at 4 ± 1 ℃. © The Author(s) 2016.

    PP and L has been monitoring temperatures in the Susquehanna SES reactor building with digital temperature recorders since 1986. In early 1990, data from four representative areas was analyzed to determine the temperature in each area which would produce the same rate of degradation as the distribution of actual temperatures recorded over about 40 months. From these effective average temperatures, qualified life multipliers were determined for activation energies in the range of 0.5 to 1.5 and those multipliers were used to estimate new qualified lives and the number of replacements which might be saved during the life of the plant. The results indicate that pursuing a program of determining EQ qualified lives from actual temperatures, rather than maximum design basis temperatures, will provide a substantial payback in reduced EQ driven maintenance

    uses Gaussian process modeling and an adaptive design strategy. In the final step of the workflow, parametric response surfaces are used to approximate the reservoir production forecasts and obtain their probabilistic distribution by propagating the remaining posterior uncertainty of input parameters. Dans le cadre de l’ingénierie de réservoir, des simulateurs permettent de comprendre et prédire le déplacement des fluides dans le réservoir et ainsi d’optimiser son exploitation. Ces simulateurs prennent en entrée un grand nombre de paramètres qui peuvent être entachés d’incertitudes. Afin d’assurer une production future correcte, la comparaison des différents scénarios d’exploitation possibles doit tenir compte de ces incertitudes. Les prévisions de production ne doivent pas être évaluées en ne considérant qu’un seul cas « moyen » pour chaque scénario mais en intégrant l’incertitude sur les paramètres d’entrée. Dans le cadre de champ mature où un historique de production est disponible, le formalisme Bayésien est bien adapté pour répondre au problème des prédictions sous incertitudes. En effet, il permet de définir les incertitudes, dites a posteriori, sur les entrées du modèle de réservoir en prenant en compte à la fois les données statiques et dynamiques. Ces incertitudes a posteriori peuvent ensuite être propagées afin de calculer des prévisions de production probabilistes pour chaque scénario, tout en respectant la connaissance statique et dynamique du réservoir. Mais l’obtention des incertitudes a posteriori ainsi que la propagation de celles-ci sur les prévisions de production nécessitent un nombre souvent prohibitif de simulations du modèle réservoir. Dans cet article, nous proposons une application de plusieurs techniques statistiques avancées afin de prendre en compte les incertitudes dans les prévisions de production pour un champ mature et ce en utilisant un nombre raisonnable de simulations.

    1976-04-01

    Relationships among symptomatology, socioeconomic status, and parenting styles were examined for 113 hyperkinetic/minimal brain dysfunction boys from intact families. Primary symptoms (e.g. hyperactivity) did not vary as a function of SES, but SES-related differences emerged for secondary symptoms (e.g., aggressive behavior, self-esteem deficits) and for parenting variables. Parenting variables were found to be better predictors of secondary symptoms than was SES. Implications for further research are offered.

    La coordination de sécurité pour l'installation du LHC et de ses expériences a été mise en place lors du démantèlement du LEP. Depuis, les contractants et les surveillants de chantier ont fait beaucoup de progrès en matière de sécurité et les procédures en vigueur sont maintenant suivies. Néanmoins, des accidents et incidents se produisent encore et pourraient être facilement évités. Un incident important, des dommages sérieux aux équipements, ou pire un accident mortel affecteraient sérieusement le projet LHC. L'analyse des causes des accidents récents révèle toujours une marge d'amélioration, en particulier en ce qui concerne l'analyse à priori des procédures l'installation et des méthodes de travail. L'intégration des aspects de sécurité dès la phase de conception et l'application stricte des règles dans tout le projet sont les clefs pour une meilleure sécurité des chantiers. Ceci ne peut être réalisable que si la sécurité est abordée de la même manière que la qualit...

    2005-01-01

    Le soudage de l'aluminium requiert un savoir-faire spécifique pour éviter la formation, dans la soudure, de défauts rédhibitoires tels que les manques de fusion ou soufflures. Ces défauts ont pour causes principales la présence d’une couche d'alumine, une diffusivité thermique élevée et une solubilité très faible de l’hydrogène dans le métal à l’état solide. Les règles de l’art à appliquer pour la préparation des assemblages et pour le choix des paramètres de soudage sont rappelées.

    1994-01-01

    The microbiological safety, refrigeration shelf-life, and nutritional quality of chicken breast meat were investigated following combined electron-beam irradiation and cooking under vacuum (sous-vide). Chicken breast meat inoculated with 10 6 CFU/g of Listeria monocytogenes was irradiated with an electron beam at doses up to 3.1 kGy under vacuum in barrier bags, cooked in a boiling water bath for 3 min 45 s (previously determined to achieve an internal temperature of 71.1 o C), and stored at 8 o C for up to 5 weeks. Listeria was undetectable in samples treated with combined sous-vide and irradiation at 3.1 kGy, but the organism survived the sous-vide treatment without irradiation and multiplied during storage. A similar study, conducted with uninoculated chicken breast meat, revealed that the product which received both irradiation (3 kGy) and sous-vide treatment had a shelf-life of at least 8 weeks at 8 o C, whereas the unirradiated samples treated sous-vide spoiled in 16 days. Listeria was undetectable in combination treated samples, but some of the unirradiated sous-vide samples tested after long storage showed high levels of Listeria. Some loss of thiamine occurred with the combined treatments. (author)

  5. Integral modeling and financial impact of the geothermal situation and power plant at Soultz-sous-Forets

    Heidinger, Ph.

    2010-01-01

    The science about deep Enhanced Geothermal Systems (EGS) is still an emerging process and for further spreading economics is the key of the technology. To understand the financial situation, a program for economic evaluation was developed. This software (Euronaut) is completely modularized and considers all cash flows. Projects like an EGS are wrapped into tree-like structures. Based on the results which were gained at Soultz-sous-Forets, two configurations were designed. The first EGS configuration consists of a simplified two well (doublet) system where the dependencies of all components (mainly the reservoir, wells, pumps and the heat-to-power conversion unit) are physically and economically linked together. The realization of these dependencies and their complex interactions enable a sensitivity analysis of the borehole depth and reservoir depth, respectively. As a result, depth dependent effective costs and revenues of an EGS plant with the geohydrological characteristics of Soultz-sous-Forets are determined. As a future development, the second configuration will adapt the actual situation at Soultz-sous-Forets with the individual features of all four wells (GPK1 - GPK4). Then, this model can be used for all kinds of sensitivity analyses to clarify the impact of certain components or to optimize the operation scheme; e.g. the flow rates. (author)

    Experimental batches of smoked-cured pork in stewed beans sauce were inoculated with spores of psychrotrophic Bacillus cereus, more heat and radiation resistant than spores of non-proteolytic C. botulinum. After vacuum packaging, the meals were treated with combinations of pasteurizing heat treatments and gamma irradiation of 5 kGy. Prior and after treatments, and periodically during storage at 10 deg. C, total aerobic and total anerobic viable cell counts, and selectively, the viable cell counts of B. cereus and sulphite-reducing clostridia have been determined. The effects of the treatment order as well as addition of nisin to enhance the preservative efficiency of the physical treatments were also studied. Heat-sensitization of bacterial spores surviving irradiation occurred. The quality-friendly sous-vide cooking in combination with this medium dose gamma irradiation and/or nisin addition increased considerably the microbiological safety and the keeping quality of the meals studied. However, approx. 40% loss of thiamin content occurred as an effect of combination treatments, and adverse sensorial effects may also limit the feasible radiation doses or the usable concentrations of nisin.

    Full Text Available Le modèle de démocratie libérale occidentale serait-il approprié à une analyse des nouveaux régimes politiques de la Troisième Vague démocratique? Dans cet article, après une récapitulation de la littérature sur la démocratisation et la réforme économique, on fait état de quelques concepts significatifs: gouvernabilité, gouvernance et démocratie, ainsi que de leurs biais normatifs implicites. On a examiné surtout le concept de démocratie qui se fonde sur le procedural minimum de Schumpeter/Dahl. Bien que considérée trop étroite par des auteurs importants, cette définition de démocratie, qui a reçu des qualificatifs la précisant davantage, a gagné du terrain. Au lieu d’en rajouter d’autres à la liste de Dahl, on propose ici qu’on tienne compte, lors de l’étude des régimes en changement, des caractéristiques du processus de décision en tant qu’instrument analytique à même d’identifier les nouveaux systèmes politiques selon leurs propres termes. Cette approche semble plus pertinente pour l’examen du caractère plus ou moins démocratique des régimes en construction dans les périodes entre les élections, faisant ressortir la question du contrôle vertical des bureaucraties, insuffisamment traitée par la théorie démocratique. On réussit à identifier aussi différents types de démocratie qui associent de façon diverse les caractéristiques de leur processus de décision. Enfin, à partir du cas brésilien, on présente quelques considérations sur le type de régime politique que les pays émergents sont capables de construire, ou se disposent à construire, tout en leur suggérant quelques hypothèses de travail et d’analyse.

    Les tuméfactions de la région sous mandibulaire sont une entité pathologique fréquente, caractérisées par un tableau clinique et une démarche diagnostique stéréotypée, et une unicité presque constante au plan chirurgical. Notre travail est une étude rétrospective sur une période de 5 an d'une série consécutive de 42 cas de tuméfactions sous mandibulaires qui ont été colligés au service d'oto-rhino-laryngologie et de chirurgie cervico-faciale de l'hôpital militaire Avicenne de Marrakech. L’âge moyen des patients était de 41 ans. Une prédominance masculine a été retrouvée. Le tableau clinique a été dominé par la tuméfaction sous mandibulaire. Tous les patients ont bénéficié d'une échographie cervicale. La tomodensitométrie cervicale a été réalisée chez 7 patients. La première étiologie était la sous maxillite chronique lithiasique dans 39,02% des cas. Le traitement était chirurgical dans tous les cas. En comparant les résultats avec ceux rapportés dans la littérature, nous allons discuter les différents aspects diagnostiques et thérapeutiques des étiologies les plus fréquentes. Les tuméfactions de la région sous mandibulaire sont fréquentes, nécessitant une démarche diagnostique rigoureuse et une prise en charge thérapeutique adaptée. PMID:25469195

    2012-02-01

    The widespread use of fetal ultrasonography results in a frequent antenatally observation of hydronephrosis, ureteropelvic junction obstruction (UPJO) accounting for the greatest fraction of congenital obstructive nephropathy. UPJO may be considered, in most cases, as a functional obstructive condition, depending on defective fetal smooth muscle/nerve development at this level, with lack of peristaltic wave propagation--aperistaltic segment--and, therefore, poor urine ejection from the renal pelvis into the ureter. The UPJO-related physiopathologic events are, at first, the compliant dilatation of renal pelvis that, acting as hydraulic buffer, protects the renal parenchyma from the rising intrapelvic pressure-related potential damages, and, subsequently, beyond such phase of dynamic balance, the tubular cell stretch-stress induced by increased intratubular pressure and following parenchymal inflammatory lesions: inflammatory infiltrates, fibroblast proliferation, activation of myofibroblasts, tubulo-interstitial fibrosis. Reactive oxygen species (ROS), nitric oxide (NO), several chemo- and cytokines, growth factors, prostaglandins and eicosanoids, angiotensin-II are the main pathogenetic mediators of the obstructive nephropathy. Apoptosis of tubular cells is the major cause of the tubular atrophy, together with epithelial-mesenchymal transdifferentiation. Some criticisms on tout court semantic renal pelvis dilatation-obstruction connection have been raised considering that the renal pelvis expansion isn't, in any case, linked to an ostructive condition, as it may be verified by diuretic (furosemide) renogram together with scintiscan-based evaluation of differential renal function. In this regard, rather than repetitive invasive nuclear procedures that expose the children to ionizing radiations, an intriguing noninvasive strategy, based on the evaluation of urinary biomarkers and urinary proteome, can define the UPJO-related possible progress of parenchymal lesions

    A special requirement of the law for apothecaries in Nancy in 1764 imposed on the candidates for a master's degree was the written response to four questions following their practical examinations. Two documents heretofore unpublished show the results of this obligation: the Conclusions de Pharmacie by Joseph Pierson (1765) and the Conclusions de Pharmacie et de Chimie by François Mandel (1771). The authors of the present article comment on these documents and make an attempt to place them in the confused history of "synthèses" and "thèses".

    Full Text Available An increasing body of research provides evidence that socioeconomic status (SES was significantly related to children’s reading development; however, the psychological mechanism underlying the association between them remained an open question. The present study is designed to test the hypothesized three-path effect of vocabulary knowledge and morphological awareness as mediators between SES and sentence reading comprehension in Chinese first-graders. Results of mediation model showed that SES exerted its effect on sentence reading comprehension through the indirect path via the simple mediating effect of morphological awareness and the three-path mediating effect of vocabulary knowledge and morphological awareness. The findings highlight a previously unidentified mechanism of the relationship between SES and reading comprehension in Chinese young children.

    A high pressure experimental water loop has been made for studying the detection and evolution of cladding failure in a pressurized reactor. The loop has been designed for a maximum temperature of 360 deg. C, a maximum of 160 kg/cm{sup 2} and flow rates up to 5 m{sup 3}/h. The entire loop consists of several parts: a main circuit with a canned rotor circulation pump, steam pressurizer, heating tubes, two hydro-cyclones (one de-gasser and one decanter) and one tubular heat exchanger; a continuous purification loop, connected in parallel, comprising pressure reducing valves and resin pots which also allow studies of the stability of resins under pressure, temperature and radiation; following the gas separator is a gas loop for studying the recombination of the radiolytic gases in the steam phase. The preceding circuits, as well as others, return to a low pressure storage circuit. The cold water of the low pressure storage flask is continuously reintroduced into the high pressure main circuit by means of a return pump at a maximum head of 160 kg /cm{sup 2}, and adjusted to the pressurizer level. This loop is also a testing bench for the tight high pressure apparatus. The circulating pump and the connecting flanges (Oak Ridge type) are water-tight. The feed pump and the pressure reducing valves are not; the un-tight ones have a system of leak recovery. To permanently check the tightness the circuit has been fitted with a leak detection system (similar to the HRT one). (author)Fren.

  4. Investigation of persistent Multiplets at the EGS reservoir of Soultz-Sous-Forêts, France

    During the exploitation of geothermal reservoirs, abundant seismicity is generally observed, especially during phases of hydraulic stimulations. The induced seismicity at the Enhanced Geothermal System of Soultz-Sous-Forêts in France, has been thoroughly studied over the years of exploitation. The mechanism at its origin has been related to both fluid pressure increases during stimulation and aseismic creeping movements. The fluid-induced seismic events often exhibit a high degree of similarity and the mechanism at the origin of these repeated events is thought to be associated with slow slip process where asperities on the rupture zone act several times.To have a better understanding of the mechanisms associated with such events and on the damaged zones involved during the hydraulic stimulations, we investigate the behavior of the multiplets and their persistent nature over several water injection intervals. For this purpose, we analyzed large datasets recorded from a borehole seismic network for several water injection periods (1993, 2000). For each stimulation interval, thousands of events are recorded at depth. We detected the events using a STA/LTA approach and classified them into families of comparable waveforms using an approach based on cross-correlation analysis. Classification of the seismic events is then improved depending on their location within the multiplets. For this purpose, inter-event distances within multiplets are examined and determined from cross-correlation analysis between pairs of events. These distances are then compared to the source dimensions derived from the estimation of the corner frequencies estimation. The multiplets properties (location, events size) are then investigated within and over several hydraulic tests. Hopefully these steps will lead to increase the knowledge on the repetitive nature of these events and the investigation of their persistence will outline the heterogeneities of the structures (regional stress

    2017-01-01

    This article explores the impact of patient and healthcare provider communication (PPC) on the HIV testing behaviors of middle socioeconomic status (SES) Black women in North Carolina. We explore how PPC about STIs and HIV (or the lack thereof) affects the provision of STI/HIV testing by either confirming the need for middle SES Black women to test routinely or potentially deterring women from feeling they need to be tested. After conducting 15 qualitative interviews with middle SES Black women between 25 and 45 years of age, we uncovered the role of patient self-advocacy in promoting HIV testing among middle SES Black women when they communicate with their healthcare providers. We discuss the importance of healthcare providers engaging their middle SES Black female patients in routine discussions about sexual health and sexual risk reduction, regardless of providers' perceptions of their potential STI/HIV risk. We recommend including SES as a variable in data collection and research in order to better understand how social class, race, and gender affect sexual health behavior and the provision of STI and HIV/AIDS prevention to diverse populations.

  7. Faulting mechanisms and stress regime at the European HDR site of Soultz-sous-Forets, France

    2006-01-01

    The state of stress and its implications for shear on fault planes during fluid injection are crucial issues for the HDR (Hot Dry Rock) or EGS (Enhanced or Engineered Geothermal System) concept. This is especially true for hydraulic stimulation experiments, aimed at enhancing the connectivity of a borehole to the natural fracture network, since they tend to induce the shearing of fractures, which is controlled by the local stress regime. During the 2000 and 2003 stimulation tests at Soultz-sous-Forets, France, about 10,000 microearthquakes were located with a surface seismological network. Hundreds of double-couple (DC) focal mechanisms were automatically determined from first-motion polarities using the FPFIT program [Reasenberg, P.A., Oppenheimer, D., 1985. FPFIT, FPPLOT and FPPAGE: Fortran computer programs for calculating and displaying earthquake fault-plane solutions. US Geological Survey Open-File Report 85-739, 25 pp.]. The majority of these mechanisms indicate normal-faulting movement with a more or less pronounced strike-slip component. Some quasi-pure strike-slip events also occurred, especially in the deeper part of the stimulated rock volume, at more than 5 km depth. Although we found a double-couple solution for all events, we tried to observe and quantify the proportion of the non-double-couple (NDC) component in the seismic moment tensor for several microseisms from the 2003 data. The study shows that the NDC is higher for the events in the vicinity of the injection well than for the events far from the well. We used the method of Rivera and Cisternas [Rivera, L., Cisternas, A., 1990. Stress tensor and fault-plane solutions for a population of earthquakes. Bull. Seismol. Soc. Am. 80, 600-614.] to perform the inversion of the deviatoric part of the stress tensor from P-wave polarities. This method was applied to different datasets from the 2000 test, taken from the shallower and deeper parts of the stimulated region. The results show a stable

    Objective. This study examined how family environmental characteristics served as mediators in the relationship between socioeconomic conditions and infant growth in a cohort of Chilean infants. Methods. We studied 999 infants, born between 1991 and 1996, from a longitudinal cohort which began as an iron deficiency anemia preventive trial. SES (Graffar Index), the Life Experiences Survey, and the Home Observation for Measurement of the Environment (HOME) were assessed in infancy. Using path analysis, we assessed the relationships between the social factors, home environment, and infant growth. Results. During the first year, weight and length gain averaged 540 grams/month and 6.5 cm/month, respectively. In the path analysis model for weight gain, higher SES and a better physical environment were positively related to higher maternal warmth, which in turn was associated with higher average weight gain. Higher SES was directly related to higher average length gain. Conclusions. In our cohort, a direct relationship between SES and length gain developed during infancy. Higher SES was indirectly related to infant weight gain through the home environment and maternal warmth. As the fastest growing infants are at risk for later obesity, new strategies are needed to encourage optimal rather than maximal growth. PMID:22666275

    The effect of blanching (95 +/- 3 degrees C) followed by sous vide (SV) processing (90 degrees C for 10 min) on levels of two polyacetylenes in parsnip disks immediately after processing and during chill storage was studied and compared with the effect of water immersion (WI) processing (70 degrees C for 2 min.). Blanching had the greatest influence on the retention of polyacetylenes in sous vide processed parsnip disks resulting in significant decreases of 24.5 and 24% of falcarinol (1) and falcarindiol (2) respectively (p processing did not result in additional significant losses in polyacetylenes compared to blanched samples. Subsequent anaerobic storage of SV processed samples resulted in a significant decrease in 1 levels (p levels was observed (p > 0.05). 1 levels in WI processed samples were significantly higher than in SV samples (p processing with losses of up to 70% occurring after 5 days storage. 1 type polyacetylene undergoes degradation such as oxidation, dehydrogenation when thermally treated forming oxidized form of 1 type molecules, in this case falcarindione, dehydrofalcarinol, dehydrofalcarinone. Thermal processing had a significant effect on instrumental color of parsnip samples compared to minimally processed in both SV and WI processed samples resulting in parsnip disks becoming darker, yellower and browner following processing and storage.

    Socioeconomic status (SES) is a complex construct of multiple indicators, known to impact cancer outcomes, but has not been adequately examined among pediatric AML patients. This study aimed to identify the patterns of co-occurrence of multiple community-level SES indicators and to explore associations between various patterns of these indicators and pediatric AML mortality risk. A nationally representative US sample of 3651 pediatric AML patients, aged 0-19 years at diagnosis was drawn from 17 Surveillance, Epidemiology, and End Results (SEER) database registries created between 1973 and 2012. Factor analysis, cluster analysis, stratified univariable and multivariable Cox proportional hazards models were used. Four SES factors accounting for 87% of the variance in SES indicators were identified: F1) economic/educational disadvantage, less immigration; F2) immigration-related features (foreign-born, language-isolation, crowding), less mobility; F3) housing instability; and, F4) absence of moving. F1 and F3 showed elevated risk of mortality, adjusted hazards ratios (aHR) (95% CI): 1.07(1.02-1.12) and 1.05(1.00-1.10), respectively. Seven SES-defined cluster groups were identified. Cluster 1 (low economic/educational disadvantage, few immigration-related features, and residential-stability) showed the minimum risk of mortality. Compared to Cluster 1, Cluster 3 (high economic/educational disadvantage, high-mobility) and Cluster 6 (moderately-high economic/educational disadvantages, housing-instability and immigration-related features) exhibited substantially greater risk of mortality, aHR(95% CI)=1.19(1.0-1.4) and 1.23 (1.1-1.5), respectively. Factors of correlated SES-indicators and their pattern-based groups demonstrated differential risks in the pediatric AML mortality indicating the need of special public-health attention in areas with economic-educational disadvantages, housing-instability and immigration-related features.

    Full Text Available Cet article propose d’évaluer le rôle des artistes, et plus particulièrement des squats d’artistes, dans la gentrification. La littérature anglo-saxonne insiste en effet beaucoup sur le rôle déterminant de l’arrivée d’artistes plus ou moins marginaux (ceux de la scène dite off dans le déclenchement de la gentrification d’un quartier. Ces artistes sont considérés non seulement comme des initiateurs de la revalorisation symbolique des quartiers qu’ils investissent, mais aussi comme des ferments d’un changement d’ambiance qui permettrait l’arrivée de gentrifieurs plus aisés. Cet article met à l’épreuve ce schéma explicatif à partir de l’étude du cas de Belleville à Paris. Il mobilise pour ce faire deux enquêtes, l’une sur le rapport à leur quartier des habitants de deux rues particulièrement gentrifiées, l’autre sur le marché immobilier. Il apparaît que les artistes sont plus des témoins ou des indicateurs de la gentrification que des déclencheurs ou des catalyseurs. Ils sont partie prenante d’un mouvement de revalorisation de la centralité et de ses ressources (notamment culturelle qui les dépassent. Ce mouvement les dépasse d’autant plus que l’éthique « artiste » s’est largement diffusée dans toutes les couches de la société.This article aims at reassessing the role of artists, and more specifically the role of squatters in the gentrification process. The Anglo-American literature argues that artists influx, especially the underground ones (that we call off, is the key element to trigger the gentrification process in a neighbourhood. These artists are considered as pioneers of the symbolic revalorisation process and as the agent of atmosphere change that brings wealthier gentrifiers to settle down.

    Full Text Available The goal of this study was to evaluate sous vide fish and assess the influence of time and temperature on the pasteurization process through quality parameters. The raw material (tambaqui fillets and the sous vide underwent physical, physicochemical, and microbiological analyses. A sauce was prepared containing soy sauce, water, horseradish and garlic flakes. The product's pasteurization parameters of time and temperature were defined according to a 22 central composite rotatable design (CCRD, and the dependent variables were water holding capacity (WHC and instrumental texture aiming at obtaining high WHC values for the product to maintain the desired juiciness. The microbiological analysis required by legislation have indicated that the fish fillets and sous vide were within de standard. The values of total coliforms found in the samples (fillets and sous vide analyzed were below the critical level of 10² CFU/g. The counts of sulphite-reducing clostridia and psychrotrophic and mesophilic bacteria on plates in the samples were <1x10 CFU/g. In conclusion, temperature was the most important factor in the pasteurization process, significantly contributing to the quality of the final product. The mathematical models proposed were considered predictive for each response.

  19. Les enjeux des marchés du colza et de ses dérivés

    Full Text Available Le colza représente dans l’Union Européenne (UE la première graine oléagineuse produite localement, la principale huile végétale produite et consommée dans cette zone, et une source de protéines pour l’alimentation animale de grande importance à côté du tourteau de soja essentiellement importé sous forme de graines et de tourteaux à partir de l’Amérique du Nord et du Sud. Alors que les marchés potentiels des co-produits du colza, de plus en plus diversifiés, demeurent très importants pour l’alimentation humaine, animale et les usages techniques, la production n’augmente que faiblement depuis un certain nombre d’années en raison d’une part de la difficile compétition de cette culture par rapports aux autres spéculations végétales de l’UE et notamment au blé, et d’autre part de la forte pression sur les prix qu’exerce l’environnement international, où dominent de plus en plus les tourteaux de soja pour les matières riches en protéines et les huiles de palme et de soja pour les matières grasses végétales. Cette situation est d’abord en relation avec l’évolution de la Politique Agricole Commune (PAC où, depuis la mise en place de l’Agenda 2000, les graines oléagineuses ont subi un découplage « vers le bas » avec un abaissement des aides directes pour ces produits au niveau de celles attribuées aux céréales, alors qu’aux Etats-Unis, depuis le Fair Act de 1996, le soja comme les autres oléagineux a bénéficié d’un découplage « vers le haut », avec l’attribution à ces produits des mêmes avantages que pour les céréales. La transformation du soutien par les prix aux producteurs de soja et autres oléagineux en soutien des revenus par la création des Marketing Loans a contribué à un effondrement des prix mondiaux des huiles et tourteaux à partir de 1998 qui a pénalisé l’ensemble des producteurs mondiaux d’oléagineux et notamment ceux de l’UE.

    Full Text Available De acordo com o Banco Mundial, desde o final dos anos 2000 o movimento de aquisição de terras por estrangeiros tem se acentuado nos países em desenvolvimento, impulsionado pelo boom dos preços das commodities. Em termos teóricos, a abordagem da Nova Economia Institucional (NEI argumenta que as instituições são importantes para as estratégias dos agentes econômicos e seu desempenho. Neste estudo, apoiado na NEI, pretende-se responder como as instituições presentes em países periféricos refletem o processo de aquisições de terras por investidores estrangeiros. Para esse objetivo, foram utilizados dados secundários de organizações internacionais, como Food and Agriculture Organization, Banco Mundial, Conferência das Nações Unidas sobre Comércio e Desenvolvimento, Fundo Monetário Internacional, Organização para a Cooperação Econômica e Desenvolvimento Econômico, Wall Street Journal e agências nacionais. A hipótese principal é que a força ou a fraqueza presente no ambiente institucional em países em desenvolvimento tem influência relevante no nível de Investimento Estrangeiro Direto (IED. Para testar a hipótese, adota-se como metodologia a análise estatística, na qual se verifica a relação entre o nível de IED nos países receptores (variável dependente contra variáveis independentes: liberdade de investimento, direitos de propriedade e nível de corrupção.

    Chicken breast dipped with citric acid (CA) was treated by sous vide processing and stored in a refrigerated state for 0, 3, 6, 9, and 14 d. A non-dipped control group (CON) and three groups dipped in different concentrations of citric acid concentration were analyzed (0.5%, 0.5CIT; 2.0%, 2CIT and 5.0%, 5CIT; w/v). Cooking yield and moisture content increased due to the citric acid. While the redness of the juice and meat in all groups showed significant increase during storage, the redness of the citric acid groups was reduced compared to the control group (pacid reactive substances (TBARS) were generally lower in the citric acid-treated samples than in untreated ones, indicating extended shelf life of the cooked chicken breast dipped in citric acid solution. The shear force of the 2CIT and 5CIT groups was significantly lower (pcitric acid concentrations. PMID:26761885

    Forty-five lamb loins were subjected to sous-vide cooking at different combinations of temperature (60, 70 and 80 °C) and time (6, 12 and 24 h) to assess the effect on the oxidative stability of lipids and proteins. Heating induced both lipid and protein oxidation in lamb loins. Higher cooking temperature-time combinations increased conjugated dienes and decreased thiobarbituric reactive substances (TBARS) values and hexanal. Total protein carbonyls increased throughout time at all cooking temperatures considered, while α-aminoadipic (AAS) and γ-glutamic semialdehydes (GGS) increased when cooking at 60 °C but not at 80 °C. Links between the decrease in secondary compounds from lipid oxidation due to cooking at higher temperatures and for longer times with the increased levels of 3-methylbutanal and greater differences between total protein carbonyls and AAS plus GGS were hypothesised.

    There is a well-established socioeconomic gradient in smoking behavior: those with lower socioeconomic status smoke more. However, much less is known about the mechanisms explaining how SES is linked to smoking. This study takes a social-ecological perspective by examining whether socioeconomic status affects smoking behavior by differential exposure to places where smoking is allowed. Exposure to smoking restrictions was assessed in real-time using Ecological Momentary Assessment methods. A sample of 194 daily smokers, who were not attempting to quit, recorded their smoking and information about situational and contextual factors for three weeks using an electronic diary. We tested whether a smoker's momentary context mediated the relationship between socioeconomic status (educational attainment) and cigarettes smoked per day (CPD). Momentary context was operationalized as the proportion of random assessments answered in locations where smoking was allowed versus where smoking was not allowed. Data were analysed using multilevel regression (measurements nested within participants) with a lower level mediation model (2-1-1 mediation). Although no significant direct effect of SES on CPD were observed, there was a significant indirect effect of SES on CPD via the momentary context. Compared to participants with higher education, lower educated participants were more likely to encounter places where smoking was allowed, and this in turn, was associated with a higher number of CPD. These findings suggest that SES is associated with smoking at least partially via differential exposure to smoking-friendly environments, with smokers from lower SES backgrounds accessing more places where smoking is allowed. Implications for current smoke-free legislation are discussed. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Part I. Methods are described for obtaining the equations for a system of elements containing fissile matter: a) by using the balance after fission, b) by using the balance before fission, c) by the evolution equations. All these methods lead to equivalent matrices whose greatest proper value is the multiplication coefficient for the system K. It is shown how to calculate K. From this it is possible to deduce the rules which generalize the criterion for the bounded solid angle. An IBM 7094 programme applies this theory to the calculation of the installations made up of a maximum of 500 elements. It calculates the effective values of K, the leaks, the solid angles and then K. Part. II. This sub-programme calculates the shielding between the elements. (authors) [French] Sommaire, - Annexe I.

The maximum temperature for exposure of magnesium to moist air without any risk of corrosion is 350 deg. C. Indeed, the oxidation rate follows a linear law above 350 deg. C although it reaches a constant level and keeps on very low under 350 deg. C. However, as far as corrosion is concerned this temperature limit can be raised up to 500 deg. C if moist air is very slightly charged with fluorinated compounds. Under pressure of CO{sub 2}, these three materials oxidate much more slowly even if 500 deg. C is reached. The higher is the temperature, the higher is the constant level of the weight increase and the quicker is reached this one.

During high temperature annealings the bubbles situated on the polygonization lattice grow much faster than those which are distributed inside the crystal. In the case of uranium the bubbles are either distributed at random, or grouped in flat accumulations which can give rise to transgranular cracks, according to the state of the metal and the irradiation temperature. At high temperature an intergranular de-cohesion is also observed.

Une enquête a été réalisée en 2013 dans quinze principales zones piscicoles sur les caractéristiques technico-économiques des fermes, le profil socio-économique des promoteurs et les pratiques aquacoles, particulièrement l’alimentation des poissons. Les résultats révèlent que 71 % des pisciculteurs enquêtés utilisent des sous-produits agricoles durant au moins un stade de production. Parmi eux, 53 % utilisent exclusivement des sous-produits. Le son de riz (52 % et le mélange de sons de riz et de maïs (28 % sont les plus utilisés. Les prix moyens de ces sous-produits varient entre 20 et 105 FCFA/kg. Oreochromis niloticus et Heterotis niloticus sont les principales espèces élevées en polyculture sur les fermes. Les sous-produits sont utilisés en système semi-intensif, extensif et en rizipisciculture, en majorité en zone rurale. Les pisciculteurs sont pour la plupart des agriculteurs, âgés de plus de 40 ans. Les taux d’utilisation des sous-produits sont plus élevés dans les régions de l’Ouest, du Centre-Ouest et du Sud-Ouest de la Côte d’Ivoire, par rapport à celles du Sud et de l’Est. Les rendements des fermes sont relativement faibles (544 à 2445 kg/ha/an, avec des gains moyens quotidiens de 0,87 et 9,97 g/j pour le tilapia et l’heterotis respectivement. L’analyse des stratégies des acteurs suggère la nécessité de définir des mécanismes d’accompagnement et de financement de la pisciculture, afin que ces acteurs puissent améliorer les formulations alimentaires à partir des matières premières locales et accessibles.

    Full Text Available The selectivity property of the SES stations, IOA, PIR and PAT in western Greece, based on reported precursory SES signals and associated large earthquakes (Mw≥5.4 that occurred from 1983 to the end of 2008, has been examined. Interesting temporal dependence of the sensitive ability of these stations has been unveiled. Physical mechanisms for the observed changes in selectivity might be related with tectonic and geodynamic events. For instance, selectivity for IOA exhibits a time dependence, for PAT probably is related to the activation of Wadati-Benioff zone while for PIR seems to be related to the specific tectonics of two confined areas such as the Cephalonia Transform Faulting zone in Ionian Sea and the southwestern part of the Hellenic Trench.

    This study examined the effects of the verbal labels procedure and vocabulary skills on low-socioeconomic status (SES) preschool children's eyewitness memory. Children (N = 176) aged 3-5 years witnessed a conflict event and were then questioned about it in either a standard or a verbal labels interview. Findings revealed that children with higher rather than lower vocabulary skills produced more complete and accurate memories. Children who were given the verbal labels interview recalled more information, which included both correct and incorrect details. Overall, the verbal labels procedure did not improve children's performance on direct questions, but children with low vocabulary skills answered direct questions more accurately if they were given the verbal labels interview than when they were not. Implications of the findings for memory performance of low-SES children are discussed. Copyright © 2014 John Wiley & Sons, Ltd.

    The present study examined the relevance of communalism, operationalized as a cultural orientation emphasizing interdependence, to maternal prenatal emotional health and physiology and distinguished its effects from those of ethnicity and childhood and adult SES. African American and European American women (N=297) were recruited early in pregnancy and followed through 32 weeks gestation using interviews and medical chart review. Overall, African American women and women of lower socioeconomic backgrounds had higher levels of negative affect, stress and blood pressure, but these ethnic and socioeconomic disparities were not observed among women higher in communalism. Hierarchical multivariate regression analyses showed that communalism was a more robust predictor of prenatal emotional health than ethnicity, childhood SES, and adult SES. Communalism also interacted with ethnicity and SES, resulting in lower blood pressure during pregnancy for African American women and women who experienced socioeconomic disadvantage over the life course. The effects of communalism on prenatal affect, stress, and physiology were not explained by depressive symptoms at study entry, perceived availability of social support, self-esteem, optimism, mastery, nor pregnancy-specific factors, including whether the pregnancy was planned, desired after conception, or how frequently the woman felt happy to be pregnant. This suggests that a communal cultural orientation benefits maternal prenatal emotional health and physiology over and above its links to better-understood personal and social resources in addition to economic resources. Implications regarding culture as a determinant of maternal prenatal health and well-being and as a potentially important lens for examining ethnic and socioeconomic inequalities in health are discussed.

    In the first part the development and operation of a glass electrode under pressure at room temperature is described. The pressure equilibrium between the inside and outside of the glass membrane several centimetres thick is obtained instantaneously by means of a siphon. The use of a silicone oil as electrical insulator makes possible the working of the glass electrode with the siphon at high pressures (100 kg/cm{sup 2}). In the second part, we determined the pH of various buffer solutions up to 250 deg. C using a cell of our design having two hydrogen electrodes. The values thus obtained for the buffer solutions make it possible to verify and calibrate the pH electrodes independently of the oxido-reduction potential of the medium. In the third part we give the results obtained up to 200 deg. C with the glass electrodes developed in conjunction with the Societe St Gobain. (author) [French] Dans une premiere partie, nous exposons la mise au point et le fonctionnement d'une electrode en verre sous pression a la temperature ordinaire. L'equilibrage instantane de la pression a l'interieur et a l'exterieur de la membrane en verre de quelques diziemes de millimetres d'epaisseur s'effectue par l'intermediaire d'un siphon. L'emploi d'une huile de silicone comme isolant electrique a permis le fonctionnement de l'electrode en verre a siphon sous haute pression (1000 kg/cm{sup 2}). Dans une deuxieme partie, nous avons determine jusqu'a 250 deg. C les valeurs du pH des diverses solutions tampons avec une cellule de notre conception a deux electrodes d'hydrogene. Les valeurs des solutions tampons ainsi obtenues permettent de verifier et d'etalonner les electrodes a pH independantes du potentiel d'oxydo-reduction du milieu.

    This study examined the ways in which body mass index (BMI) percentile - an identified risk factor for overweight and cardiovascular disease in adulthood - develops from birth through early adolescence. In addition, we examined whether psychosocial factors, such as parenting style and maternal depression, mediated the link between socio-economic status (SES) and BMI growth. Design. Data were obtained from phases 1-3 of the National Institute of Child Health and Human Development (NICHD) Study of Early Child Care and Youth Development (SECCYD) - a longitudinal study that followed children from 10 communities in the United States from birth to age 11. We applied growth mixture models to identify distinct subtypes of BMI development. Within these models, we performed between- and within-class mediation analyses to examine whether SES predicted class membership or differences in development within each class via maternal depression and parenting styles. Results identified three prototypic trajectories of BMI percentile growth, elevated, steady increase, and stable. We found evidence for both between- and within-class mediation, suggesting multiple pathways by which SES can affect BMI development. These findings add to the research that suggests that being in a family with a low SES is associated with falling into patterns of development characterized by early and lasting increases in BMI relative to one's peers, and that this association is partly accounted for by maternal depression and parenting styles. What is already known? Past research has found evidence that patterns of childhood overweight are impacted by socioeconomic status through psychosocial factors like parenting and depression. This evidence is often limited to individual points in time where neglectful, permissive, and authoritarian parenting and higher levels of maternal depression are associated with higher levels of overweight status among children from infancy to adolescence. However, little

    Microfractures appearing in thin section as fluid inclusion trails in quartz crystals were studied in four core samples of Soultz-sous-Forets granite. Their orientations in four series of three mutually perpendicular thin sections were estimated using a previously described apparent dip method and a new method involving measurements of strike and apparent dips. Three samples display three microfracture sets and one sample displays two sets. In all samples, one set is nearly vertical and strikes N-S. In two samples, one and two sets are nearly vertical and strike E-W. In two samples, two sets strike NW-SE: one is vertical, the other dips gently to the NE (or SW). Comparing microfracture and mesofractures sets in the same cores shows that (1) the N-S microfacture set is always dominant at both scales and (2) all other microfracture sets have no mesoscopic counterpart. The N-S microfracture sets could have been created during E-W extension of earliest Cenozoic age (Rhine Graben rifting). Differences between the two scales are explained by a {sigma}{sub 1}/{sigma}{sub 2} switching which occurred at the crystal scale and generated mutually perpendicular cracks.

    This comprehensive final report for the Swiss Federal Office of Energy (SFOE) takes a look at the activities carried out during the period from April 2004 up to May 2009 at Soultz-sous-Forets, France, in connection with the enhanced geothermal systems (EGS) at that location. The report describes the work performed by the Swiss EGS Research and Development group involved in the Soultz project. The principal target set was to install and operate a power plant, enabling the deep reservoir/heat exchanger to be operated, evaluated and improved under realistic conditions. The Swiss contributors have been participating in several work packages: Short and long term tests and medium-term tests of the three-well reservoir/heat exchanger system, development and up-scaling, technical and economic design of larger, industrial, EGS units and the development of stimulation methodology for EGS. The exchange of findings obtained during this project phase is discussed, as is the state-of-the-art of EGS stimulation methods, the interpretation of logging data. Also, seismic /-hydraulic factors, the evaluation of the production/injection performance of the boreholes and reservoir development strategies are discussed as are the modelling of geochemical impact of forced fluid circulation in the deep geothermal reservoir and the results of chemical stimulation tests performed on site.

    There is a variety of different food processing methods, which can be used to prepare ready-to-eat foods. However, the need to preserve the freshness and nutritional qualities leads to the application of mild technologies which may be insufficient to inactivate microbial pathogens. In this work, fresh chicory stems were packed under a vacuum in films, which were transparent to microwaves. These were then exposed to microwaves for different periods of time. The application of sous vide microwave cooking (SV-MW, 900 W, 2450 MHz), controlled naturally occurring mesophilic aerobic bacteria, yeasts and molds for up to 30 d when vacuum-packed vegetables were stored at 4 °C. In addition, the process lethality of the SV-MW 90 s cooking was experimentally validated. This treatment led to 6.07 ± 0.7 and 4.92 ± 0.65 log cfu/g reduction of Escherichia coli and Listeria monocytogenes inoculated over the chicory stems (100 g), respectively. With an initial load of 9 log cfu/g for both pathogens, less than 10 cfu/g of surviving cells were found after 90 s cooking. This shows that short-time microwave cooking can be used to effectively pasteurize vacuum-packed chicory stems, achieving >5 log cfu/g reduction of E. coli and L. monocytogenes. © 2017 Institute of Food Technologists®.

    The current study explores the influence of socioeconomic status (SES) and bilingualism on the linguistic skills and verbal short-term memory of preschool children. In previous studies comparing children of low and mid-high SES, the terms "a child with low-SES" and "a child speaking a minority language" are often interchangeable, not enabling differentiated evaluation of these two variables. The present study controls for this confluence by testing children born and residing in the same country and attending the same kindergartens, with all bilingual children speaking the same heritage language (HL-Russian). A total of 120 children (88 bilingual children: 44 with low SES; and 32 monolingual children: 16 with low SES) with typical language development, aged 5; 7-6; 7, were tested in the societal language (SL-Hebrew) on expressive vocabulary and three repetition tasks [forward digit span (FWD), nonword repetition (NWR), and sentence repetition (SRep)], which tap into verbal short-term memory. The results indicated that SES and bilingualism impact different child abilities. Bilingualism is associated with decreased vocabulary size and lower performance on verbal short-term memory tasks with higher linguistic load in the SL-Hebrew. The negative effect of bilingualism on verbal short-term memory disappears once vocabulary is accounted for. SES influences not only linguistic performance, but also verbal short-term memory with lowest linguistic load. The negative effect of SES cannot be solely attributed to lower vocabulary scores, suggesting that an unprivileged background has a negative impact on children's cognitive development beyond a linguistic disadvantage. The results have important clinical implications and call for more research exploring the varied impact of language and life experience on children's linguistic and cognitive skills.

    Objectives Children in families of low socioeconomic status (SES) have been found to have poor sleep, yet the reasons for this finding are unclear. Two possible mediators, presleep worries and home environment conditions, were investigated as indirect pathways between SES and children’s sleep. Participants/Methods The participants consisted of 271 children (M (age) = 11.33 years; standard deviation (SD) = 7.74 months) from families varying in SES as indexed by the income-to-needs ratio. Sleep was assessed with actigraphy (sleep minutes, night waking duration, and variability in sleep schedule) and child self-reported sleep/wake problems (e.g., oversleeping and trouble falling asleep) and sleepiness (e.g., sleeping in class and falling asleep while doing homework). Presleep worries and home environment conditions were assessed with questionnaires. Results Lower SES was associated with more subjective sleep/wake problems and daytime sleepiness, and increased exposure to disruptive sleep conditions and greater presleep worries were mediators of these associations. In addition, environmental conditions served as an intervening variable linking SES to variability in an actigraphy-derived sleep schedule, and, similarly, presleep worry was an intervening variable linking SES to actigraphy-based night waking duration. Across sleep parameters, the model explained 5–29% of variance. Conclusions Sleep environment and psychological factors are associated with socioeconomic disparities, which affect children’s sleep.

    Socioeconomic risks (SES risks) are robust risk factors influencing children's academic development. However, it is unclear whether the effects of SES on academic development operate universally in all children equally or whether they vary differentially in children with particular characteristics. The current study aimed to explore children's temperament as protective or risk factors that potentially moderate the associations between SES risks and academic development. Specifically, latent growth modeling (LGM) was used in two longitudinal datasets with a total of 2236 children to examine how family SES risks and children's temperament interactively predicted the development of reading and math from middle childhood to early adolescence. Results showed that low negative affect, high effortful control, and low surgency mitigated the negative associations between SES risks and both reading and math development in this developmental period. These findings underline the heterogeneous nature of the negative associations between SES risks and academic development and highlight the importance of the interplay between biological and social factors on individual differences in development. © 2015 John Wiley & Sons Ltd.

    To compare the clinical outcome of a multiplex polymerase chain reaction (PCR) based molecular diagnostic method -- Syndrome Evaluation System (SES) directed treatment strategy vs. standard of care (blood culture) directed treatment strategy for neonatal sepsis. This randomized controlled trial (RCT) included 385 neonates with sepsis who were randomized into two groups -- SES and control (BACTEC). Both tests were performed for all the neonates. However, in the SES group, the results of SES test were revealed to the treating clinicians, while in the control group, SES results were withheld. Two ml of blood was drawn from each baby. One aliquot was sent for blood culture, whereas the remaining aliquot was sent for SES. Babies were then administered empirical IV antibiotics and given supportive care. Further antibiotic changes, if required were done in SES and control groups based on their respective reports. The microbiological profile, immediate outcome, duration of hospital stay, number of antibiotics used and readmission within a month in both groups were compared. SES was better than BACTEC in identifying the causative organism in both the groups (68 % vs. 18 % in SES group and 72 % vs. 18 % in control group). SES had 100 % concordance with blood culture by BACTEC. Detection of bacteria and fungi were four and ten-fold higher respectively with SES when compared to BACTEC culture. Microbiological diagnosis was rapid with SES compared to BACTEC (7 h vs. 72 h). Treatment based on SES resulted in significantly less mortality (3 % vs. 18 %). Readmission rate, duration of hospital stay and change in antibiotics were also significantly less in SES group. This new molecular based diagnostic system (SES) helps in rapid and accurate diagnosis of neonatal sepsis and reduces mortality and morbidity in affected neonates.

    The 3-SES-149A well, at a water depth of 1164 meters, is part of the SEAL-100 block located offshore of the State of Sergipe. The objective of the intervention was to evaluate the 3674-3682 meters interval of the Riachuelo Formation. Bottom hole gauges and real time data transmission to the surface were deployed for this test, during which the target interval produced gas and condensate, without any evidence of formation of hydrate at the surface. After the test, while pulling out the electrical cable with the Link Running Tool, it got stuck close to the subsea well-test tree at a depth of 1257 meters. The formation of hydrate not only kept the cable from moving up, but also rendered impossible the reverse circulation in the column and consequently pulling out the test string. Removing the hydrate would allow releasing the logging cable, thus enabling fluid circulation in the string and its safe retrieval. The goal was achieved via the injection of solvent through the subsea well-test tree, drilling fluid circulation through the annulus above the BOP, and fluid circulation on the top of the hydrate plug through Coiled Tubing. The greatest challenge was running the Coiled Tubing in the string with the electrical cable inside. (author)

    Ce memoire presente des mesures de transport thermoelectrique, les effets Seebeck et Nernst, dans une serie d'echantillons de supraconducteurs a haute temperature critique. Des resultats obtenus recemment au Laboratoire National des Champs Magnetiques Intenses a Grenoble sur La1.7Eu0.2Sr0.1 CuO4, La1.675Eu0.2Sr0.125CuO 4, La1.64Eu0.2Sr0.16CuO4, La1.74Eu0.1Sr0.16CuO4 et La 1.4Nd0.4Sr0.2CuO4 sont analyses. Une attention particuliere est accordee aux equations de la theorie semi-classique du transport et leur validite est verifiee. La procedure experimentale et les materiaux utilises pour concevoir les montages de mesures sont expliques en detail. Enfin, un chapitre est dedie a l'explication et l'interpretation des resultats de transport thermoelectrique sur YBa2Cu3O6+delta publies au cours de l'hiver 2010 dans les revues Nature et Physical Review Letters. Les donnees d'effet Seebeck dans les echantillons de La 1.8-x,Eu0.2SrxCuO 4, ou un changement de signe est observe, permettent de conclure a la presence d'une poche d'electrons dans la surface de Fermi qui domine le transport a basse temperature dans la region sous-dopee du diagramme de phase. Cette conclusion est similaire a celle obtenue par des mesures d'effet Hall dans YBa 2Cu3O6+delta et elle cadre bien dans un scenario de reconstruction de la surface de Fermi. Les donnees d'effet Nernst recueillies indiquent que la contribution des fluctuations supraconductrices est limitee a un modeste intervalle de temperature au-dessus de la temperature critique.

  10. Underground storage touted as CO2 solution

    International Nuclear Information System (INIS)

    Kishewitsch, S.

    2000-01-01

    As power generating companies weigh the merits of switching from coal to natural gas in order to reduce carbon dioxide emissions into the atmosphere, energy analysts predict that coal will remain a major contributor to world energy supplies well into the 21st century. For example, the Electric Power Institute estimates that a new 1,000 MW power plant need to be built somewhere in the world every two days for the next fifty years to meet the global demand for energy, and that in major emerging economies such as India and China, many of those plants will be fueled by coal. Various methods already are being tried to safely contain the carbon dioxide resulting from this vastly carbon-intensive economy. One of the more promising approaches involves burying the gas deep in the ground where it will stay safely for hundreds, if not thousands of years. Burial underground may take the form of burial in deep exhausted oil or gas formations, or burial in the deep ocean. Injection into exhausted oil and gas formations is favoured because of the ready availability of thousands of gigatonnes of underground formations and because of the extensive knowledge base already in existence regarding the size and geological properties of oil and gas reservoirs and the behaviour of carbon dioxide under these conditions. Injecting carbon dioxide into unmineable coal seams could replace methane bound to the coal; it is already being done in Alberta as one of the two pilot projects in North America, the other being in Mexico. Carbon dioxide injection to stimulate enhanced oil recovery is also being experimented with, among others by PanCanadian Resources Ltd at its Weyburn reservoir in Saskatchewan. Injection into salt domes and deep saline aquifers is another alternative. Sequestration in the ocean in a variety of forms is also the subject of several experiments. To illustrate the attractiveness of deep ocean storage, it is stated that the ocean contains at least 50 times more carbon than the atmosphere does, therefore adding carbon dioxide to the sea from the combustion of fossil fuels would have a proportionately smaller effect. It is estimated that once stored in the deep ocean, carbon dioxide would not make its way back into the atmosphere for at least 400 to 500 years; at the very least, this delay would give us time to develop technology to deal with the problem as well as to develop different sources of energy. DOE claims that improved carbon dioxide sequestration technology to meet GHG reduction targets could result in cumulative savings to the U.S. economy of $ 2.7 trillion by 2050

    L’analyse porte sur des productions langagières verbales et non-verbales les plus ordinaires entre des adultes et de très jeunes enfants âgés de moins de deux ans. En articulant les notions de l’évocation de l’absent et du déjà-là, notions qui mettent en avant le processus d’une «temporalité-spatialisée», je problématise la genèse d’un soi comme objet qui se donne à voir dans et par l’activité discursive. Mon hypothèse est que, s’agissant du tout jeune enfant qui ne peut donc s’auto-thématiser ni référer à lui-même de façon explicite, c’est bien dans l’évocation d’autrui et d’autres objets du monde qu’indirectement, il nous «parle» de lui. Trois éléments viennent étayer ma réfl exion pour répondre à la problématique posée : les notions de temporalité, de spatialité et d’affect. Elles sont clairement présentes dans les initiatives de demande, dans les mouvements des échanges et dans les séquences «pré-narratives» produites par l’enfant. Au vu des corpus, ces trois notions m’ont paru inséparables du lieu même où elles font ancrage, à savoir : l’interaction et le dialogue avec l’autre. L’approche adoptée dans l’analyse pour argumenter l’idée de l’expression d’un «parler de soi» chez le tout jeune enfant n’est pas tant, au sens strict, de type linguistique que de type pragmatique. Aussi, j’analyse les effets réciproques entre l’interaction et les échanges qui la modèlent.

Tests are carried out in the range of erature reached in the CO{sub 2} cooled reactors (vessel, thermal shield, pipes). The observed weight increases are small, even after more than a thousand hours of heating at 350 deg. C, but oxidation curve looks like progressing linearly. Furthermore, the oxide formed under a pressure of 15 kg/cm{sup 2} is undoubtedly more compact and adherent than the one formed under a pressure of 1 kg/cm{sup 2}. Finally, for practical use, CO{sub 2} steel pipes surface has to be sand blast and pickled.

    Full Text Available El presente trabajo tiene como objetivo describir tendencias a partir de algunos indicadores de calidad de vida en el conjunto de países de dependencia mineral. A partir de gráficos Box-Plot e índices de correlación, se procedió a la descripción de tendencias estadísticas para realizar precisiones en torno a la calidad de vida -analizada a través del índice de desarrollo humano [ÍDH] y componentes- y variables económicas [exportaciones minerales como porcentaje del total de exportaciones y del producto interno bruto] y demográficas [fecundidad, mortalidad infantil]. Aunque no se precisó alguna correlación estadística entre el porcentaje de exportaciones minerales como parte del PIB con el ÍDH o alguno de sus componentes, se encontró relación significativa con el porcentaje como parte del total de exportaciones aunque -en su relación con el IDH y con el índice de logro educativo- sólo había relaciones inversas de carácter leve. En relación con las variables demográficas, sólo se encontró relaciones leves entre el porcentaje de exportaciones minerales sobre exportaciones totales con la tasa de fecundidad total y la tasa de mortalidad infantil, sin que se haya encontrado alguna significatividad en la tasa de mortalidad de niños menores de 5 años. Se precisó que, aunque la mayor parte de los países con dependencia mineral poseen valores ÍDH medio, los valores reflejan fuertes diferencias regionales, distribuciones asimétricas positivas matizadas en lo referente a las exportaciones minerales y dispersión desigual de los valores ÍDH, siendo mayor entre los países de alta dependencia mineral.

El artículo analiza los avances obtenidos por los países en desarrollo en las negociaciones de la Ronda de Doha en dos temas centrales del debate mundial sobre propiedad intelectual: los productos farmacéuticos y el conocimiento tradicional, y deja abierto el debate sobre el retroceso que el auge de la vía bilateral podría significar para la defensa de sus intereses. El objetivo de este artículo es evidenciar que a pesar de que los plazos previstos para finalizar la Ronda de Doha se han incumplido, el plazo inicial era el 1o de enero de 2005 y en diciembre de 2005 los miembros se propusieron extraoficialmente concluir las negociaciones a finales de 2006 –plazo que tampoco se cumplió– y que hasta ahora sólo puede ser calificada de fracaso –el bloqueo de las negociaciones obligaron a su suspensión indefinida en julio de 2006–, no debe desconocerse que, en lo que al Acuerdo sobre los ADPIC se refiere, permitió que los países en desarrollo iniciaran una ofensiva que no podrían haber contemplado veinte años atrás. Así, gracias al carácter multilateral de la OMC que tantas críticas ha despertado, en los países desarrollados han logrado defender sus intereses en un tema de vital importancia para sus reivindicaciones como es el del acceso a medicamentos y han abierto el debate para que finalmente se reconozca el derecho que tienen de proteger y beneficiarse de los conocimientos tradicionales.

    The purpose of the research was to determine whether European American and Latino mock jurors would demonstrate bias in death penalty decision making when mitigation evidence and defendant ethnicity and socioeconomic status (SES) were varied. A total of 561 actual venire persons acted as mock jurors and read a trial transcript that varied a defendant's case information (mitigating circumstances: strong/weak, defendant ethnicity: European American/Latino, and defendant SES: low/high). European American jurors recommended the death penalty significantly more often for the low SES Latino defendant when strength of mitigation evidence was weak. In addition, they also assigned this defendant higher culpability ratings and lower ratings on positive personality trait measures compared with all other conditions. Strong mitigation evidence contributed to lower guilt ratings by European American jurors for the high SES European American defendant. Latino jurors did not differ in their death penalty sentencing across defendant mitigation, ethnicity, or SES conditions. Discussion of in-group favoritism and out-group derogation, as well as suggestions for procedures to diminish juror bias in death penalty cases, is provided. (c) 2015 APA, all rights reserved).

Depuis lors, on s'est rendu compte que les radiolesions pouvaient resulter d'effets indirects, etre tardives, reparables, et le plus souvent modifiables par des traitements chimiques ou biochimiques ad hoc. Cependant, la percee decisive en radiobiologie se situe entre 1962 et 1964, avec la decouverte que la cellule possede un mecanisme de defense active vis-a-vis de tout ce qui peut porter atteinte a l'integrite du patrimoine genetique inscrit dans la structure meme de l'ADN. L'existence d'une quatrieme fonction de l'ADN, celle d'auto-reparation, par voie enzymatique sous controle genetique, apporte enfin a la radiobiologie la base biologique moleculaire qui lui manquait pour sortir de la nuit 'phenomenologique' ou elle s'etait enfoncee apres l'abandon de la generalisation de la theorie de Lea, faute de preuve experimentale. Dans la seconde partie, cette fois prospective, de l'etude l'auteur tente une synthese elargie en considerant le role que peut jouer cette fonction de reparation de l'ADN non seulement du point de vue de la survie des systemes biologiques irradies en presence ou non d'agents modificateurs de dose ou mutagenes, mais aussi de celui de l'evolution naturelle ou artificielle de ces systemes sous rayonnement. Les donnees les plus recentes de la litterature sont en accord avec ce qui ne constitue encore qu'une hypothese generale de recherche.

    To evaluate the association between dental caries experience and preventive behaviours of children residing in a deprived area in Clermont-Ferrand (France). All 4-5 yr-olds attending nine schools in deprived areas of the city were invited to participate and 81% (n=282) consented and were examined. Dental caries was recorded at the dentine threshold. Parents completed a questionnaire concerning family demographics and the child's use of fluoride. Non-parametric tests and logistic regression assessed the relative importance of SES and fluoride variables on dental status (dt>1). Fifty four (19%) of the examined children were living in families with an immigrant background, 33% were fully covered by the national health insurance programme for deprived families. Caries experience was high; mean dft was 1.94 (3.31) and 30% of the children had >1 carious teeth. Thirty percent of the families reported using fluoridated salt. Tooth brushing once daily was reported for 39% and twice daily for 26%. Parents declared supervising tooth brushing for 60%. Two thirds of the children, according to their parents, used fluoride supplement between birth and two years. Supervised tooth brushing was significantly correlated with lower mean dt scores. Systemic fluoride use was poorly related to dental caries Immigrant background, family size, type of health insurance and mother's unemployment were significantly correlated with caries prevalence. In multivariate analysis, immigrant status, supervised tooth brushing and parental knowledge about fluoride in toothpastes were significant caries predictors. The majority of low SES children did not practice effective caries prevention; few reported twice daily brushing with fluoride toothpaste. Caries experience was very high and much was untreated. Immigrant status, supervised tooth brushing and parental knowledge about fluoride in toothpastes were significant caries predictors.

    Broiler breast ( pectoralis major ) meat was submitted to salting with NaCl + NaNO 3 followed by a drying process to produce jerky-type chicken. The final product (raw broiler charqui) was desalted and then cooked using grilled, roasted, fried and sous-vide techniques. Sous-vide cooked samples showed lowest results of moisture loss compared to roasted and fried ones. Fatty acid profile suffered minor changes after cooking of broiler charqui. Regarding to protein oxidation, tryptophan fluorescence, protein carbonylation and disulphide bonds formation of chicken charqui were affected by cooking temperature while free thiol groups, Schiff base formation and hardness were mostly impacted by the length of cooking. Instrumental color of broiler charqui was affected by the type of cooking, being closely related with Maillard products formation. In conclusion, sous-vide technique seems to be the most advantageous cooking method to obtain high-quality ready-to-eat chicken charqui.

    This study aimed to determine the influence of cooking temperature (either 60 ℃ or 80 ℃) and time (6 h or 24 h) on the physicochemical (weight loss, moisture content, instrumental color, instrumental texture, lipid and protein oxidation) and microbiological changes underwent by sous-vide cooked lamb loins during refrigerated storage for 30 days. There was a slight trend to decreasing weight losses in some of the cooking treatments, but only in samples cooked at 60 ℃ for 6 h it was paralleled with an increase in moisture content. The only noteworthy oxidative change was a marked decrease in conjugated dienes after two weeks of storage in samples cooked at 80 ℃ for 24 h. Neither instrumental texture nor color showed noticeable variations during the storage. Microbial population remained quite low during the whole refrigerated storage. Overall, most of the studied parameters showed only scarce changes throughout 30 days of refrigerated storage that most likely would not influence the quality of sous-vide cooked loin lambs. © The Author(s) 2014.

    Selection tests were carried out on commercial steels from the viewpoint of their resistance to oxidation in carbon dioxide, under 25 atmospheres pressure, between 350 and 600 deg. C. Comparative curve of oxidation kinetics were obtained, from which the influence of various additive elements can be found; small amounts of aluminium particularly seem to be favourable in the case of only slightly alloyed steels. (author) [French] Des essais de selection d'aciers commerciaux ont ete effectues quant a leur resistance a l'oxydation dans le gaz carbonique, sous pression de 25 atmospheres, ente 350 et 600 deg. C. Des courbes comparatives de cinetique d'oxydation ont ete obtenues, ce qui permet de degager l'influence de divers elements d'addition; de faibles teneurs en aluminium apparaissent notamment favorables dans le cas des aciers peu allies. L'acier inoxydable 18-8 a egalement ete etudie, notamment sous forme de tubes minces. Son comportement est bon jusqu'au moins 600 deg. C dans ces conditions. (auteur)

    Lamb loins were subjected to sous-vide cooking at different combinations of temperature (60, 70, and 80 °C) and time (6, 12, and 24 h). Different physicochemical, histological and structural parameters were studied. Increasing cooking temperatures led to higher weight losses and lower moisture contents, whereas the effect of cooking time on these variables was limited. Samples cooked at 60 °C showed the highest lightness and redness, while increasing cooking temperature and cooking time produced higher yellowness values. Most textural variables in a texture profile analysis showed a marked interaction between cooking temperature and time. Samples cooked for 24h showed significantly lower values for most of the studied textural parameters for all the temperatures considered. Connective tissue granulation at 60 °C and gelation at 70 °C were observed in the SEM micrographs. The sous-vide cooking of lamb loins dramatically reduced microbial population even with the less intense heat treatment studied (60 °C-6 h). Copyright © 2012 Elsevier Ltd. All rights reserved.

    Le besoin de maîtriser les déformations des sols sous les remblais destinés à recevoir les structures de lignes à grande vitesse, en fait un enjeu important pour ces projets. Toutefois, de nombreuses difficultés ont été soulevées liées principalement au grand nombre d'incertitudes qui entourent le phénomène. En effet, la caractérisation géologique et géotechnique dépend de sondages et d'essais où le risque de remaniement est important et dont l'interprétation est, souvent, délicate. Cet article présente une procédure de calcul qui permettrait en pratique d'évaluer le tassement sous remblai avec une bonne précision et qui a été validée sur un certain nombre d'ouvrages. Pour cela, des corrections sont introduites aux méthodes usuelles de calcul permettant d'approcher les valeurs mesurées sur chantier.

    The kinetics and mechanisms of the reaction of pure or low alloyed magnesium with various gas saturated by water vapor: oxygen, argon, nitrogen, air, carbon dioxide, have been studied and compared in the temperature range 350-600 deg C. After picturing the large chemical reactivity of magnesium surface, the more or less properties of the oxide film, always made of magnesia, have been shown depending on the nature of the gas carrying water vapor; in fact, metal sublimation occurs the more easily as the surrounding atmosphere is less oxidizing. Moreover, an activation energy change is systematic, but at a temperature which depends also on the latter. In the case of the alloys, the linear oxidation rate is generally obtained only after short induction periods, parabolic in nature. Two possibilities of corrosion inhibition of magnesium by water vapor are then demonstrated and explained: either by a partial superficial fluoridation, or when the carrier gas is carbon dioxide. Also, the extreme conditions of oxidation were studied, that is the ignition processes that occur at a particular temperature in every gas mixture. Finally, it is tried to evolve the fundamental and practical significance of all the results. (author) [French] On a etudie et compare par voie thermogravimetrique, micrographique et radiocristallographique, les cinetiques et les mecanismes de reaction du magnesium et de certains de ses alliages avec diverses atmospheres saturees en vapeur d'eau: oxygene, argon, azote, air, gaz carbonique, dans un domaine de temperatures s'etendant de 350 a 600 deg C, Apres avoir illustre l'extreme sensibilite chimique de la surface du magnesium, on a tout d'abord montre que la valeur plus ou moins protectrice de la couche d'oxyde formee, pourtant toujours constituee de magnesie normale, depend de la nature du gaz porteur de la vapeur d'eau; en effet, la sublimation du metal intervient d'autant plus facilement que les atmospheres en presence sont moins oxydantes.

    effective diffusivity varying with contact force and on-going convergence. The results agree broadly with those of previous compaction creep experiments performed using wet halite powder. Discrepancies with other workers results for single-contact dissolution experiments can be explained in terms of differences in experimental configuration and competition between driving forces. La dissolution sous contrainte (IPS - Intergranular Pressure Solution représente un mécanisme de lithification, de compaction et de déformation à l'échelle géologique pour une large gamme de roches. Les études expérimentales d'IPS réalisées sur des agrégats de quartz n'ont pas été couronnées de succès en raison d'un taux faible d'IPS, et les expériences IPS réalisées en utilisant une halite saturée comme analogue de roche (Spiers et Schutjens, 1990 ; Hickman et Evans, 1991 ont laissé des incertitudes quant au détail des mécanismes IPS et à la structure/saturation au contact du grain dans ce matériau. La présente étude fait état de quatre expériences de dissolution de contact réalisées sous microscope optique afin d'étudier le mécanisme et la cinétique de l'IPS pour des contacts simples halite/halite et halite/verre, chargés en eau salée (température ambiante. Des forces normales de contact dans la gamme de 1,0 à 2,6 N ont été appliquées en présence d'eau salée saturée en NaCl, induisant des pressions de 0,8 à 7,4 MPa. Des pertes de masse et des convergences - fonction du temps - ont été observées pour tous les contacts. Dans tous les cas, le fait de charger le contact (ou d'augmenter la charge sur le contact a conduit à la formation immédiate d'une morphologie de contact rugueuse, composée d'un motif d'îles et de canaux, contrôlé par des caractéristiques cristallographiques, à l'échelle de quelques microns.

    Youth with Type 1 diabetes (T1D) from single-parent families have poorer glycemic control; a finding confounded with socioeconomic status (SES). Family density (FD), or youth:adult ratio, may better characterize family risk status. Structural equation modeling assessed the relation of single-parent status, SES, and FD to parenting stress, diabetes-related conflict, parental monitoring, adherence, and glycemic control using cross-sectional parent and youth data (n = 257). Single-parent status exhibited similar relations as SES and was removed. Lower FD was associated with better glycemic control (β = -.29, p = .014) via less conflict (β = .17, p = .038) and greater adherence (β = -.54, p single-parent status were indistinguishable from those of SES. FD provides distinct information related to adolescent glycemic control. © The Author 2015. Published by Oxford University Press on behalf of the Society of Pediatric Psychology. All rights reserved.

    The ability to adaptively inhibit responses to tempting/distracting stimuli in the pursuit of goals is an essential set of skills necessary for adult competence and wellbeing. These inhibitory capacities develop throughout childhood, with growing evidence of important maturational changes occurring in adolescence. There also has been intense interest in the role of social adversity on the development of executive function, including inhibitory control. We hypothesized that the onset of adolescence could be a time of particular opportunity/vulnerability in the development of inhibition due to the large degree of maturational changes in neural systems involved in regulatory control. We investigated this hypothesis in a longitudinal study of adolescents by examining the impact of socioeconomic status (SES) on the maturation of inhibition and concurrent brain function. Furthermore, we examined gender as a potential moderator of this relationship, given evidence of gender-specificity in the developmental pathways of inhibition as well as sex differences in adolescent development. Results reveal that lower SES is associated with worse behavioral inhibition over time and a concurrent increase in anterior cingulate (ACC) activation, but only in girls. We also found that lower SES girls exhibited decreased ACC ↔ dorsolateral prefrontal cortex (dlPFC) coupling over time. Our findings suggest that female adolescents with lower SES appear to develop less efficient inhibitory processing in dlPFC, requiring greater and relatively unsuccessful compensatory recruitment of ACC. In summary, the present study provides a novel window into the neural mechanisms by which the influence of SES on inhibition may be transmitted during adolescence. © 2015 Wiley Periodicals, Inc.

    In Part I we present a multidisciplinary analysis model for the prediction of functional connections between the design variables and the electromagnetical, electrical and thermal performances of a brushless permanent magnet motor. In this paper we have elaborated a design methodology for electrical motors supplied from a variable-frequency low-voltage source. The objective is to take into account the influence of the inverter's dynamics from the beginning of the design, for the same reasons as we do for electromechanical and thermal constraints. The procedure is based on a Sequential Quadratic Programming optimization method. Two techniques are used to take into account the influence of the inverter: the first one develops the performance analysis with the multidisciplinary model; the second one considers the inverter's current reference as a supplementary optimization variable for the control of the design. Optimization difficulties linked to the chopping of the converter are discuted in connection with a sensitivity analysis of the torque, with respect to the inverter's current reference; a method is proposed to enhance the performances of the algorithm. The method has been applied to the design of a permanent magnet brushless DC motor used in the propulsion system of an electrical scooter; evolution of the design with the complexity level of analysis model is evidenced. Dans une première partie nous avons développé un modèle d'analyse pluridisciplinaire qui établissait les dépendances fonctionnelles entre les variables de conception et les performances magnéto-électro-thermiques d'un moteur brushless à aimants permanents. Dans cet article nous décrivons une procédure de dimensionnement adaptée à la conception de la machine alimentée à fréquence variable sous faible tension.

El trabajo examina la forma en que la crisis de la deuda soberana se propagó por el sector financiero, a través de la mayor volatilidad de la rentabilidad de los activos. Lo cual se debió a una mayor variación de sus precios, lo que tuvo efectos sobre el patrimonio neto de los agentes económicos, los ingresos, la demanda agregada y la asignación del crédito, así como también sobre la producción y el empleo. Para este documento se hizo búsqueda y selección de literatura especializada y se extrajeron estadísticas especializadas de la UNCTAD, CEPAL y OECD. Se concluye que la transmisión de la crisis europea al Tercer Mundo se dio por canales específicos conocidos, como el comercio internacional, la inversión extranjera directa, las remesas y la ayuda oficial para el desarrollo.

    Development of the Soultz-sous-Forets HDR (Hot Dry Rock) geothermal energy project will involve important fluid injections which will induce micro-seismic events. This thesis discusses the natural seismicity of the region and induced seismicity associated with fluid injections. A catalogue of all historical and instrument seismicity of the Soultz-sous-Forets (SSF) region has been compiled. This seismicity does not correspond to movements along the major tectonic features of the region. The area around SSF has been identified as being one where high heat flow corresponds to low seismicity. The largest well documented seismic event in the region which took place in 1952 had an epicentral intensity of VI. All important data pertaining to the series of seismic events which took place in the region from August to October 1952 have been collected and are presented. This work details the installation and operation of a permanent 3 station network of accelerometers and seismometers around the HDR site. Also the installation and operation of a mobile network of vertical seismometers during fluid injections. 167 micro-seismic events were recorded on the surface network, with magnitudes from -0.5 to 1.9. The preferential alignment of the micro-seismic cloud is N160 deg. Individual focal mechanisms of the larger seismic events correspond to an extensional tectonic regime. Stress inversion of P wave polarities indicates that the maximum stress is vertical and the intermediate and minimum stress axes horizontal. The largest of the horizontal stresses is orientated N124 deg and the smallest N34 deg. Induced seismic movement is taking place on pre-existing fractures controlled by the in situ stress seismic movement is taking place on pre-existing tectonic fractures controlled by the in situ stress field, and the largest of the induced events had a magnitude 1.9. This level of seismicity does not pose any environmental hazard to the region around Soultz-sous-Forets. (author) 151

    Some Inconel samples were subjected to hot water corrosion testing (350 deg. C), under stress slightly above the elastic limit. It has been observed that different types of alloys - with or without titanium - could suffer serious intergranular damage, including a complete rupture, within a three months period. In one case, we observed an unusual intergranular phenomenon which appeared quite different from common intergranular corrosion. (author) [French] Des essais de corrosion d'Inconel sont realises dans l'eau a 350 deg. C, et sous contrainte legerement superieure a la limite elastique.

  15. Hospital daily outpatient visits forecasting using a combinatorial model based on ARIMA and SES models.

    Accurate forecasting of hospital outpatient visits is beneficial for the reasonable planning and allocation of healthcare resource to meet the medical demands. In terms of the multiple attributes of daily outpatient visits, such as randomness, cyclicity and trend, time series methods, ARIMA, can be a good choice for outpatient visits forecasting. On the other hand, the hospital outpatient visits are also affected by the doctors' scheduling and the effects are not pure random. Thinking about the impure specialty, this paper presents a new forecasting model that takes cyclicity and the day of the week effect into consideration. We formulate a seasonal ARIMA (SARIMA) model on a daily time series and then a single exponential smoothing (SES) model on the day of the week time series, and finally establish a combinatorial model by modifying them. The models are applied to 1 year of daily visits data of urban outpatients in two internal medicine departments of a large hospital in Chengdu, for forecasting the daily outpatient visits about 1 week ahead. The proposed model is applied to forecast the cross-sectional data for 7 consecutive days of daily outpatient visits over an 8-weeks period based on 43 weeks of observation data during 1 year. The results show that the two single traditional models and the combinatorial model are simplicity of implementation and low computational intensiveness, whilst being appropriate for short-term forecast horizons. Furthermore, the combinatorial model can capture the comprehensive features of the time series data better. Combinatorial model can achieve better prediction performance than the single model, with lower residuals variance and small mean of residual errors which needs to be optimized deeply on the next research step.

    L'environnement chimique de l'ADN en situation biologique est complexe notam-ment en raison de la présence d'histones, protéines nucléaires, associées en quantité approximativement égales à l'ADN pour former la chromatine. Les histones possèdent de nombreux radicaux basiques arginine et lysine chargés positivement et dont la majorité se trouve sur les chaînes émergentes, l'ADN présente quant à lui des charges négatives sur ses groupements phosphates localisés tout au long de la double hélice. Dans cette étude, la complexité de la structure de la chromatine nucléaire est dans un premier temps mimée en solution aqueuse par la formation de complexes entre un ADN plasmidique sonde et les trois acides aminés basiques, Arg, His, Lys, qui, mis à part His, sont protonés au pH physiologique. Ces acides aminés libres en solution sont réputés être des capteurs efficaces de radicaux libres, notamment pour le radical hydroxyle, conférant ainsi un pouvoir protecteur vis-à-vis des effets indirects sur l'ADN en situation d'exposition aux rayonnements ionisants. A concentration fixée, les capacités de capture des acides aminés libres, σ, pour le radical hydroxyle sont typiquement les suivantes σHis ≈σArg > σLys (σLys ≈ 0,1 × σArg). Nous avons mesuré les taux de cassures simple brin par plasmide et par Gray (χ) lors d'expositions de solutions aqueuses de complexes [acide aminé - ADN plasmidique] aux rayons X ultra-mous (1,5 keV). A concentrations égales, les trois acides aminés complexés et présents en large excès ne manifestent pas une capacité de protection de l'ADN proportionnelle à leur capacité de capture libre et en solution ; on trouve en effet des taux de cassures dans l'ordre suivant χHis > χArg > χLys (χLys ≈ 0,01 χArg). Après avoir détaillé le mode opératoire de ces mesures, nous analyserons sur des bases bibliographiques, les modes spécifiques d'interaction des acides aminés basiques avec l'ADN. La sp

    Full Text Available L’offensive contre l’affirmative action engagée depuis les années 1980 s’est accrue pendant les deux mandats de la présidence Bush, et l’opinion publique s’est radicalisée, percevant désormais de plus en plus fréquemment ces programmes comme une série d’avantages indûment octroyés à un certain nombre de « privilégiés ». Tout programme d’affirmative action doit désormais être étayé par des disparity studies démontrant la réalité de la discrimination, et seules des mesures très ciblées (narrowly tailored sont autorisées pour y remédier. La charge de la preuve a été en quelque sorte inversée. Mais contrairement aux idées reçues, l’affirmative action n’est pas sur le point de disparaître aux États-Unis et malgré son hostilité de principe, le gouvernement Bush n’a pris aucune mesure concrète pour démanteler ces programmes. L’affirmative action connaît aujourd’hui plusieurs transformations majeures, l’évolution la plus marquante étant l’effacement du critère ethno-racial au profit de critères plus neutres et moins idéologiquement polarisants, essentiellement d’ordre géographique et territorial. Dans l’enseignement supérieur par exemple, des procédures d’admission codées ont vu le jour pour favoriser l’accès des minorités ethniques sous-représentées aux campus d’élite, et diverses stratégies de contournement ont été mises en place dans l’adjudication des marchés publics. Ces transformations sont également intéressantes à analyser d’un point de vue transnational, puisque l’on observe une convergence croissante avec le modèle français de discrimination positive, lui aussi fondé sur le camouflage et l’euphémisation de l’identité ethno-raciale et sur une logique de territoire.This article examines the fate of affirmative action in the United States during the eight years of the Bush administration.

    Full Text Available El principal objetivo de este artículo es establecer una discusión sobre las condicionantes que ha conllevado la inserción internacional de los países. Se hace énfasis en la región latinoamericana. Este aspecto de la inserción internacional se presenta asociado a los componentes teóricos del desarrollo. Un desarrollo que se concibe como equitativo en lo social, sostenible en lo económico y sustentable en lo ecológico. El argumento central de este trabajo es que la inserción internacional de los países permite distinguir entre aquellos que han logrado conformar procesos de autonomía y los que han generado inserciones dependientes. Entre estos últimos –donde se ubican los latinoamericanos- se pueden distinguir países que son sociedades más funcionales, de aquellos cuya disfuncionalidad social es muy evidente. La referencia conceptual fundamental se basa por lo general, en los postulados que sobre desarrollo humano ha elaborado la Organización de Naciones Unidas, desde la publicación del primer Informe Mundial de Desarrollo en 1992.

    Full Text Available Abstract Background Recruitment, willingness to participate, and retention in interventions are indispensable for successful prevention. This study investigated the effectiveness of different strategies for recruiting and retaining low-SES women in depression prevention, and explored which sociodemographic characteristics and risk status factors within this specific target group are associated with successful recruitment and retention. Methods The process of recruitment, willingness to participate, and retention was structurally mapped and explored. Differences between women who dropped out and those who adhered to the subsequent stages of the recruitment and retention process were investigated. The potential of several referral strategies was also studied, with specific attention paid to the use of GP databases. Results As part of the recruitment process, 12.1% of the target population completed a telephone screening. The most successful referral strategy was the use of patient databases from GPs working in disadvantaged neighborhoods. Older age and more severe complaints were particularly associated with greater willingness to participate and with retention. Conclusions Low-SES women can be recruited and retained in public health interventions through tailored strategies. The integration of mental health screening within primary care might help to embed preventive interventions in low-SES communities.

Sembra trattarsi di un movimento sottoculturale che, almeno inizialmente, muove i primi passi dal punk della fine degli anni ’70. Uno degli aspetti che caratterizza questa moderna subcultura giovanile di matrice gotica è dato da una filosofia di vita nichilista e dal ricorso all’autolesionismo. Il più delle volte si tratta di giovani e adolescenti con il bisogno di cercare una propria dimensione e che, come è facilmente intuibile dalla stessa parola “emo”, sono alla ricerca di emo-zioni.Con questo lavoro, che non pretende assolutamente di essere una esaustiva trattazione del fenomeno, si cerca di gettare alcune basi per lo studio e la comprensione di quello che sembra essere un sempre più diffuso sintomo di un disagio giovanile.L’analisi delle storie di vita di alcuni giovani emo dovrebbe, pertanto, consentire se non altro di fornire un inquadramento del movimento nei suoi tratti salienti.

    Asset-based approaches have become popular in public health. As yet it is not known to what extent health and welfare professionals are able to identify and mobilise individual and community health assets. Therefore, the aim of this study was to understand professional's perceptions of health and health assets. In a low-SES neighbourhood, 21 health and welfare professionals were interviewed about their definition of health and their perceptions of the residents' health status, assets available in the neighbourhood's environment, and the way residents use these assets. A Nominal Group Technique (NGT) session was conducted for member check. Verbatim transcripts of the semi-structured interviews were coded and analysed using Atlas.ti. The professionals used a broad health concept, emphasizing the social dimension of health as most important. They discussed the poor health of residents, mentioning multiple health problems and unmet health needs. They provided many examples of behaviour that they considered unhealthy, in particular unhealthy diet and lack of exercise. Professionals considered the green physical environment, as well as health and social services, including their own services, as important health enhancing factors, whereas social and economic factors were considered as major barriers for good health. Poor housing and litter in public space were considered as barriers as well. According to the professionals, residents underutilized neighbourhood health assets. They emphasised the impact of poverty on the residents and their health. Moreover, they felt that residents were lacking individual capabilities to lead a healthy life. Although committed to the wellbeing of the residents, some professionals seemed almost discouraged by the (perceived) situation. They looked for practical solutions by developing group-based approaches and supporting residents' self-organisation. Our study shows, firstly, that professionals in the priority district Slotermeer rated

    - This camera makes it possible to carry out X-ray studies on highly oxidisable materials, up to about 900 deg. C. Most of the existing models do not provide sufficient protection against the formation of surface oxide or carbide films on the sample. The present arrangement makes it possible to operate at very low pressures: 5 x 10{sup -8} to 10{sup -7} torr, thanks to an entirely metallic apparatus. The radiation heating system consists of an incandescent lamp, outside the evacuated portion, and a reflector which concentrates the energetic flux into the sample through a silica window. The heated parts have thus only a small thermal inertia. With the apparatus it has been possible to determine the phase parameters of uranium-{alpha} up to 650 deg. C with a precision of {+-} 0.0015 A. A similar study has been carried out on a uranium-chromium alloy in the {beta}-phase up to 740 deg. C. (author) [French] Cette chambre permet l'etude, par diffraction de rayons X, de materiaux tres oxydables, ceci jusqu'a 900 deg. C environ. La plupart des modeles existant a l'heure actuelle n'assurent pas une protection suffisante de l'echantillon contre la formation de films superficiels d'oxydes ou de carbures. La disposition d'ensemble permet d'operer sous des pressions tres basses: 5.10{sup -8} a 10{sup -7} torr, grace a une construction entierement metallique. Le systeme de chauffage par rayonnement associe une lampe a incandescence, exterieure a l'enceinte sous vide, et un reflecteur, qui concentre le flux energetique sur l'echantillon, a travers un hublot de silice. Les pieces echauffees ne presentent ainsi qu'une faible inertie thermique. L'appareil a permis la determination des parametres de l'uranjum en phase a, jusqu'a 650 deg.

    D- and z-values for Listeria monocytogenes were obtained for two Mexican meat entrées: pork meat marinated in tomatillo (green tomato) sauce (PTS) and beef marinated in a red chili sauce (BRCS), with addition of 0, 200, and 800 ppm of grapefruit seed extract (GSE). Meat samples inoculated with L. monocytogenes were packaged in sterile bags, immersed in a water bath, and held at 55, 57.5, 60, and 62.5°C for different periods of time. Depending upon the temperature, D-values at 0 ppm of GSE ranged from 26.19 to 2.03 min in BRCS and 26.41 to 0.8 min in PTS. Adding 800 ppm of GSE to BRCS thermally treated at 55 and 62.5°C significantly decreased inactivation time by 35%. A reduction in time of 25.9, 10.6, and 40.1% at 55, 57.5, and 60°C, respectively, was observed in PTS with 800 ppm of GSE. The z-values of L. monocytogenes were not significantly affected by GSE addition; average z-values were 7.25 and 5.09°C for BRCS and PTS, respectively. Estimated thermal lethality for a 7-D log reduction of L. monocytogenes under commercial-size sous-vide conditions at a reference temperature of 55°C was reached at 78 and 71 min for BRCS without and with 800 ppm of GSE, respectively. For PTS, 7-D reduction was attained at 69 and 61 min without and with addition of 800 ppm of GSE, respectively. Supplementing both Mexican meat entrées (BRCS and PTS) with 800 ppm of GSE rendered L. monocytogenes cells more sensitive to the lethal effect of heat. The results of this study will assist the retail food industry in designing acceptance limits on critical control points pertaining to cooking regimes to effectively eliminate L. monocytogenes in BRCS and PTS sous-vide processed Mexican meat entrées.

    Emotive anti-tobacco advertisements can increase quitting. Discrete emotion theories suggest evoking fear may be more effective than sadness; less research has focused on hope. A weekly cross-sectional survey of smokers and recent quitters (N = 7683) measured past-month quit attempts. The main predictor was level of exposure to four different types of anti-tobacco advertisements broadcast in the two months prior to quit attempts: advertisements predominantly evoking fear, sadness, hope, or evoking multiple negative emotions (i.e., fear, guilt, and/or sadness). Greater exposure to fear-evoking advertisements (OR = 2.16, p < .01) increased odds of making a quit attempt and showed similar effectiveness among those in lower and higher SES areas. Greater exposure to advertisements evoking multiple negative emotions increased quit attempts (OR = 1.70, p < .01), but interactions indicated this was driven by those in lower SES, but not higher SES areas. Greater exposure to hope-evoking advertisements enhanced effects of fear-evoking advertisements among those in higher SES, but not lower SES areas. Findings suggest to be maximally effective across the whole population avoid messages evoking sadness and use messages eliciting fear. If the aim is to specifically motivate those living in lower SES areas where smoking rates are higher, multiple negative emotion messages, but not hope-evoking messages, may also be effective.

    Full Text Available El tercer milenio inicia en un mundo globalizado, unipolar: 6.3 mil millones de personas; de ellas, 850 millones hambrientas, 1,200 sin agua potable, 2,400 sin saneamiento, 850 millones analfabetos, 10 millones de niños mueren anualmente. Mientras tanto, 10% de la población disfruta del 70% de riquezas. Proliferan estallidos sociales, guerras, huracanes, terremotos, contaminación ambiental, inundaciones, calentamiento global, SIDA. Numerosas comunidades rurales se han colapsado económica y socialmente, el desempleo aumenta por tecnologías ahorradoras de fuerza laboral, persiste alta migración a las ciudades. La “Revolución Verde”, de especialización e industrialización agropecuaria de países desarrollados, ha generado conflictos ambientales y no ha sido una solución. La geofagia y sed de poder de países y políticos, generan distribución desequilibrada de riquezas. En nuestro planeta abundan resultados positivos con sistemas agroecológicos de producción que han demostrado poder resolver gran número de esos problemas. En América Latina y Cuba, existen experiencias del saber y tradiciones campesinas e indígenas, investigación y producción comercial con soluciones factibles para los problemas de este llamado “Tercer Mundo”, donde están los países más necesitados. Son evidentes los caminos posibles para alcanzar el anhelado desarrollo agropecuario. Este trabajo resume algunos ejemplos de los avances. El reto futuro es integrar los componentes de los agroecosistemas y lograr sinergias, consolidando sistemas agroecológicos holísticos, con eficiencia biológica, productiva, económica, energética y ambiental. Es esperanzador pensar que un futuro agroecológico unido a la voluntad política de desarrollo económico y social, puede contribuir en alto grado a liberar a nuestros países tercermundistas de la crítica situación actual

Un échantillon de couples avec ou sans enfant permet dans une première étude d'estimer l'impact de la présence de l'enfant sur le couple alors que deux autres études posent la question complémentaire de l'impact du couple sur l'enfant. Les résultats de ces études contribuent à démontrer l'interdépendance entre le couple et l'enfant alors que chaque membre de la famille peut-être une source d'influence sur les autres. Nous argumentons qu'une réponse aversive à des problèmes extrafamiliaux favorise des stress intrafamiliaux mais que cela se révèle surtout selon les caractéristiques des membres de la famille.

    This study evaluated the influence of different factors on pork hams cooked by sous-vide method. The quality and structural and microbiological properties of the treated samples were compared with those of controls. Samples were subjected to treatment at different combinations of temperature (61 °C or 71 °C), time (45 or 90 min), and vacuum degree (98.81% or 96.58%). The control sample was air packaged and boiled for 45 min in boiling water. Temperature and vacuum degree affected quality properties, while the effect of time was limited. Samples cooked at 61 °C showed higher moisture content, redness, and pink color of the meat juice, whereas samples cooked at 71 °C showed higher cooking loss rate, lightness, and volatile basic nitrogen values. Texture analysis indicated tenderer meat for the treatment group than the control. No microbial growth was detected in any treatment groups. Meat cooked at 61 °C and 98.81% vacuum showed more spacious arrangement of meat fiber. Copyright © 2018 Elsevier Ltd. All rights reserved.

    Full Text Available En este artículo se analiza la presencia de los países emergentes en la gobernanza global a través de la participación desplegada por ellos en el G-20, con el fin de identificar la posición de Argentina en este ámbito multilateral, y determinar el uso que hizo de su poder como potencia media. Para cumplir con este objetivo consideramos las cumbres de jefes de Estado y de Gobierno del G-20, desde la primera realizada en Washington, en 2008, hasta la novena llevada a cabo en Brisbane, en 2014. Observamos que más allá de las diferencias y disputa de intereses, países desarrollados y emergentes convergieron en sostener las Viejas instituciones internacionales como el FMI. Argentina, de participación intensa en las cumbres pero sin una estrategia de influencia, quedó fuera de esta coincidencia y perdió poder en las reformas producidas en los medios multilaterales de crédito.

  20. Integração produtiva e acordos comerciais: o caso dos países da Aladi

    Directory of Open Access Journals (Sweden)

    Karla Sarmento Gonçalves de Souza

    Full Text Available Resumo O processo de fragmentação da produção tem imprimido novas formas de organização da produção e de comércio entre os países. Dentre os diversos fatores explicativos dessa reorganização das atividades produtivas, aqueles relativos aos custos de comércio são de particular importância. Nesse sentido, os acordos comerciais podem ter uma influência relevante na formação de redes produtivas regionais e, mesmo, globais. Este artigo busca investigar se os acordos firmados no âmbito da Aladi contribuíram para aprofundar a integração produtiva na região, por meio da análise do perfil do comércio regional e da estimação de um modelo gravitacional. O grau de integração dos países da região nas redes produtivas internacionais e regionais é bem inferior aquele observado na Ásia, na América do Norte e na Europa. No entanto, as estimações sugerem que os acordos da Aladi exerceram uma influência fraca, porém, positiva sobre os fluxos regionais de partes, componentes e bens de capital.

    Full Text Available While few studies examine the online privacy practices or attitudes of young people of low socio-economic status (SES, they are often at the most risk of and most susceptible to privacy violations. This participatory, collaborative study of 28 low-SES young adults in the New York City area investigates how they view online information sharing. Like most Americans, our participants viewed online privacy as an individual responsibility. We make two primary contributions. First, participants revealed extensive awareness of the risks of sharing information online, and many avoided social media, self-censored, or obfuscated their contributions as a result. Second, many participants had extensive experience with policing and physical surveillance and were aware they could not avoid such encounters through their own efforts. This window into structural discrimination provides an alternate frame to that of “individual responsibility” that educators and researchers can use to conceptualize how privacy is violated online. Framing online privacy violations as inevitable and widespread may not only help foster activist anger and strategic resistance but also avoid the victim-blaming narratives of some media literacy efforts. By examining the experiences of these young people, who are often left out of mainstream discussions about privacy, we hope to show how approaches to managing the interplay of on- and offline information flows are related to marginalized social and economic positions.

Differences were found between countries in the magnitude of these increases, the smaller countries showing the highest levels of collaboration, especially with respect to those publications also involving scientists from institutions outside the Latin American region. The most common subject areas of intra-regional collaboration were Biology, Health, Physics, and Chemistry. Participating institutions from outside the region in intra-regional co-authorship were most commonly European (40% of cases and North American (38%. The impact of papers as measured by a normalized h-index, involving scientists from outside the region was greater than that found for all intra-regional publications. The dominant bilateral regional collaboration was between Brazil and Argentina which in recent years has focused on topics in the Health Sciences and Astronomy. A detailed analysis of Physics papers showed that institutions from Brazil and Argentina are the most productive in intra-regional collaborations and Condensed Matter, the most studied subject.

    The current study explores the influence of socioeconomic status (SES) and bilingualism on the linguistic skills and verbal short-term memory of preschool children. In previous studies comparing children of low and mid-high SES, the terms “a child with low-SES” and “a child speaking a minority language” are often interchangeable, not enabling differentiated evaluation of these two variables. The present study controls for this confluence by testing children born and residing in the same country and attending the same kindergartens, with all bilingual children speaking the same heritage language (HL-Russian). A total of 120 children (88 bilingual children: 44 with low SES; and 32 monolingual children: 16 with low SES) with typical language development, aged 5; 7–6; 7, were tested in the societal language (SL-Hebrew) on expressive vocabulary and three repetition tasks [forward digit span (FWD), nonword repetition (NWR), and sentence repetition (SRep)], which tap into verbal short-term memory. The results indicated that SES and bilingualism impact different child abilities. Bilingualism is associated with decreased vocabulary size and lower performance on verbal short-term memory tasks with higher linguistic load in the SL-Hebrew. The negative effect of bilingualism on verbal short-term memory disappears once vocabulary is accounted for. SES influences not only linguistic performance, but also verbal short-term memory with lowest linguistic load. The negative effect of SES cannot be solely attributed to lower vocabulary scores, suggesting that an unprivileged background has a negative impact on children’s cognitive development beyond a linguistic disadvantage. The results have important clinical implications and call for more research exploring the varied impact of language and life experience on children’s linguistic and cognitive skills. PMID:28890706

    . Il y a moins d'une generation, l'on croyait encore que les effets des rayonnements sur les systemes vivants etaient des effets directs, immediats, irreparables et definitifs. Depuis lors, on s'est rendu compte que les radiolesions pouvaient resulter d'effets indirects, etre tardives, reparables, et le plus souvent modifiables par des traitements chimiques ou biochimiques ad hoc. Cependant, la percee decisive en radiobiologie se situe entre 1962 et 1964, avec la decouverte que la cellule possede un mecanisme de defense active vis-a-vis de tout ce qui peut porter atteinte a l'integrite du patrimoine genetique inscrit dans la structure meme de l'ADN. L'existence d'une quatrieme fonction de l'ADN, celle d'auto-reparation, par voie enzymatique sous controle genetique, apporte enfin a la radiobiologie la base biologique moleculaire qui lui manquait pour sortir de la nuit 'phenomenologique' ou elle s'etait enfoncee apres l'abandon de la generalisation de la theorie de Lea, faute de preuve experimentale. Dans la seconde partie, cette fois prospective, de l'etude l'auteur tente une synthese elargie en considerant le role que peut jouer cette fonction de reparation de l'ADN non seulement du point de vue de la survie des systemes biologiques irradies en presence ou non d'agents modificateurs de dose ou mutagenes, mais aussi de celui de l'evolution naturelle ou artificielle de ces systemes sous rayonnement. Les donnees les plus recentes de la litterature sont en accord avec ce qui ne constitue encore qu'une hypothese generale de recherche. Des travaux portant sur les caracteres phenotypiques et genotypiques lies a l'acquisition de radioresistance gamma et UV, chez 'Escherichia coli K12', ont ete entrepris par l'auteur, en collaboration avec O.

Les auteurs exposent les raisons qui ont amene le Laboratoire de genie atomique de l'Ecole polytechnique de l'Universite de Lausanne a realiser l'assemblage sous-critique, autant que possible par ses propres moyens, et a choisir un reseau uranium faiblement enrichi-eau legere. Ils decrivent le principe et la realisation des dispositifs qui permettent de faire varier commodement et rapidement les parametres relatifs au reseau et a l'alimentation en neutrons: 1. Les barres d'uranium sont suspendues verticalement, chaque point de suspension est a deux degres de liberte sans restriction de continuite. Ce principe permet par exemple de faire varier de facon , continue te pas de reseau. 2. L'alimentation en neutrons est assuree par 5 sources Pu-Be placees dans un socle de graphite.

It is hoped that such measurements as are effected with this arrangement will be valuable in enlarging the field of application of the counters. (author) [French] 1. Les travaux consacres a la mise au point d'un dispositif de comptage destine a l'etude de la capture electronique ont montre que le diametre du, fil constituant l'anode dans un compteur proportionnel a haute pression peut avoir une influence importante sur le pouvoir de resolution en energie obtenu dans les mesures de rayonnements de faible energie. Dans un compteur travaillant sous une pression de 12 atmospheres, l'amplitude de la repartition des impulsions dues aux rayonnements de capture K de 13,5 keV a pu etre ramenee de 65% a 17%. en reduisant de 0,0076 mm a 0,0025 mm le diametre du fil. Ce phenomene est interprete comme constituant un effet de la charge spatiale en ions positifs dans l'avalanche. Pour un gain et un rayonnement primaire donnes, la densite des ions positifs dans l'avalanche s'accroit rapidement avec la pression du gaz de remplissage, et lorsque les champs electriques d'accompagnement sont assez grands pour affecter les derniers stades du processus de multiplication, le pouvoir de resolution en energie du compteur diminue. Toute diminution du diametre de l'anode entraine un accroissement du champ applique exterieurement, dans la region ou se produit la multiplication, ce qui tend a contrecarrer l'effet de la charge spatiale. L'emploi de fils d'un diametre de 0,0025 mm a donne des resultats satisfaisants lors de nouvelles mesures des rapports de capture L/K effectuees au moyen d'un dispositif de comptage a fils multiples, travaillant sous des pressions pouvant atteindre 12 atmospheres. Les resultats obtenus pour les rapports de capture L/K du Ge{sup 71} et du Kr{sup 79} sont de 0

Il s’interroge d’abord sur les conditions et les motifs qui ont permis l’existence de cette communauté médicale a priori marginale ; il en établit ensuite les principales caractéristiques en termes de formation, de parcours professionnel et d’engagement médico-sanitaire et plus largement social. Ces médecins privés apparaissent alors comme des agents actifs, non seulement compétents mais inventifs, de la médicalisation coloniale dans l’entre-deux guerres, susceptibles d’avoir améliorer de façon substantielle la santé de la population colonisée. Pour donner corps et vie à cette médecine libérale, plusieurs de ses acteurs sont évoqués et en particulier le Dr Nguyễn Văn Luyện (1898-1946. Ces fragments biographiques permettent de révéler la polyvalence, l’expertise, le dynamisme et les engagements en santé publique et en matière de soins d’un nouveau groupe social attentif aux attentes de sa communauté, autant de manifestations probantes en même temps d’une demande en santé en mutation.This paper constitutes the first account on the history of Vietnamese private medical practice during the French domination over Indochina. It aims to revisit multiple historiographies and at the same time to suggest new ways of writing the history of colonial health and health care. First, I analyse the legal and political context in which Vietnamese private doctors could emerge as a professional and as a social group. Then I insist on the main characteristics of this medical community in terms of training, professional life and scientific and social activities.

    This study examines how the intersecting consequences of race-ethnicity, gender, socioeconomics status (SES), and age influence health inequality. We draw on multiple-hierarchy stratification and life course perspectives to address two main research questions. First, does racial-ethnic stratification of health vary by gender and/or SES? More specifically, are the joint health consequences of racial-ethnic, gender, and socioeconomic stratification additive or multiplicative? Second, does this combined inequality in health decrease, remain stable, or increase between middle and late life? We use panel data from the Health and Retirement Study (N = 12,976) to investigate between- and within-group differences in in self-rated health among whites, blacks, and Mexican Americans. Findings indicate that the effects of racial-ethnic, gender, and SES stratification are interactive, resulting in the greatest racial-ethnic inequalities in health among women and those with higher levels of SES. Furthermore, racial-ethnic/gender/SES inequalities in health tend to decline with age. These results are broadly consistent with intersectionality and aging-as-leveler hypotheses. © American Sociological Association 2016.

    High density fuels, either in uranium monocarbide or in U-UC cermets have been prepared on laboratory-scale, by hot pressing of mixtures of uranium powder and graphite in suitable proportions. Uranium powder is prepared by calcium reduction of UO{sub 2} followed by an acetic leaching at low temperature. An adequate protection-treatment permits the manipulation of the powder in the open air. Uranium and Graphite powders are intimately mixed and then hot pressed in a double effect graphite die at a temperature of 900-1000 deg. C under a charge of 200 kg/cm{sup 2} during 3 hours. A special design of the die avoids the breaking of the graphite during the sintering. In this way, samples are prepared, the characteristics of which are: 1) {+-} 5 pour cent of homogeneity for a ratio height/diameter = 2. 2) almost theoretical density (98 pour cent) 3) low concentration of unreacted carbon (heat treatment of stoichiometric monocarbide can be useful for completion of reaction) 4) the micrographic examination shows: - a network of monocarbide surrounding uranium in the case of low concentration cermets (<2,5 per cent C) - two networks intimately mixed for high concentration cermets (<2,5 per cent C) - a fine grain structure for the monocarbide (10 u). 5) In every case, the X rays examinations show a fine grain structure without any orientation, and no UC{sub 2}. Some indications are given on the physical (thermal cycling, conductibility) and chemical properties (corrosion, reaction with cladding materials). (author)Fren.

  18. The Influence Of Hydrothermal Alteration And Weathering On Rock Magnetic Properties Of Granites From The Eps-1 Drilling (soultz-sous-forÊts / France)

    Science.gov (United States)

    Just, J.; Schleicher, A.; Kontny, A.; de Wall, H.

    The EPS-1 drilling in Soultz-sous-Forêts (Rhinegraben, France) recovered a core pro- file of Tertiary to Permo-Mesozoic sediments deposited on a Variscan granitic base- ment. Magnetic susceptibility (k) measurements on the core material revealed a con- tinous increase from the basement/cover boundary (kmean 0.4 x 10-3 SI) into the magnetite-bearing granite (kmean 13 x 10-3 SI) over a depth range of 1417 U 1555 m. Rock magnetic and mineralogic studies were performed for the fresh granite, the hydrothermally altered granite near a fault zone and the altered granite from the fossil land surface near the basement/cover boundary. The decrease in susceptibility can be correlated with a gradual decomposition of magnetite to hematite and an alteration of the matrix minerals feldspars, biotite and hornblende to clay minerals and carbon- ates. Along with this transition, characteristic rock magnetic signatures can be dis- criminated for different degrees of alteration. While temperature-dependent magnetic susceptibility k(T)-curves in fresh granites indicate a typical multidomain magnetite course with good reversibility, different types of irreversible courses are observed for the altered granite. However, hematite could not be identified in the k(T)-curves. Al- tered granite shows relatively weak magnetic behaviour in AF-demagnetisation exper- iments, untypical for hematite. The alteration of the fresh granite also causes a change in magnetic fabric parameter, especially of the anisotropy factor. The magnetic min- eralogy from the altered granite in respect to the changes in rock magnetic properties will be discussed.

    Full Text Available The origins of the very much appreciated "symphonie concertante" can be found in the importance of public concerts given in Paris at the end of the 18th century. The specific repertoire played at the French Court during the years 1800-1830 distinctly shows this vogue for the "symphonie concertante", for it reveals the still unknown importance of virtuosity. Considered as an musical entertainment for the pompous parties at the French Court or as an musical accompaniment for the masses given at the Imperial and Royal Chapel, this "decorative concertant syle" became an essential part of the Regime etiquette during the Napoleonic empire as well as the Restoration period. This music, perfectly incorporated into the official guidelines, will disappear as a consequence of the political events of 1830 and the arrival of a new aesthetic movement, the Romanticism.

    [fr] La vogue du concert public à Paris, à la fin du XVIIIe siècle, fut à l'origine de l'essor phénoménal que connut la symphonie concertante. Le répertoire de la musique de la Cour - entre 1800 et 1830 - est particulièrement représentatif de cette mode : il révèle une place encore insoupçonnée laissée à la virtuosité. Agrémentant les messes de la Chapelle ou les bals donnés lors de fastueuses soirées, ce « style concertant décoratif » devint un élément constitutif de l'apparat gouvernemental sous l'Empire et la Restauration. Une sorte d'académisme officiel que les événements politiques de 1830 et l'essor du romantisme musical feront définitivement disparaître.

  20. Experimental and numerical study of the stability of phyllosilicates in a strong thermal gradient. Test in the geothermal site of Soultz-sous-Forets

    Thermodynamic data of hydrated phyllosilicates, in particular clay minerals are not well known. The stability fields of these minerals are not well determined; following some authors they even do not exist. We have developed an experimental approach, in which a sequence of local equilibrium states between a fluid and minerals take place in a closed gold cell along a strong thermal gradient. The experiments were conducted in the chemical systems: Mg-Al-Si-H 2 O (MASH), K-Al-Si-H 2 O (KASH), and K-Mg-Al-Si-H 2 O (KMASH). The sequences of crystallization observed along the thermal gradient are the same if one exchanges the position of the cells containing the initial reacting materials with respect to the thermal gradient end-members. The crystallization sequences correspond to local equilibrium states. Following the temperature increase (from 200 to 350 C) one observes the following sequences: di-octahedral smectite? tri-octahedral smectite; kaolinite? donbassite? tri-octahedral chlorite; smectite? illite? muscovite; or even kaolinite? illite + smectite? donbassite; commonly observed in hydrothermal systems. They allow to develop a thermodynamic model for hydrated phyllosilicates, taking into account their hydration state as a function of temperature. This model shows the stability fields of clay minerals between 200 and 350 C.The chemical and mineralogical dynamics showed in these experimental systems has been applied to predict the possible dissolutions and/or precipitations which may take place between the circulated hot fluid and the geothermal granitic reservoir in the geothermal system at Soultz-sous-Forets. These processes may affect the duration of the geothermal reservoir, as a function of evolution in the morphology of the porosity. Our experimental approach shows that feldspars and smectites are forming the major part of the total volume of silicates which may precipitate in addition to carbonates already described in previous studies.

    Full Text Available The aim of this study was to examine the relationships among vocabulary knowledge, phonological representations and phonological sensitivity in 80 Spanish-speaking preschool children from middle- and low-SES families. Significant social class differences were obtained on all tasks except syllable matching. Regression analyses were carried out to test the predictive power of vocabulary knowledge and accuracy of phonological representations on the phonological sensitivity measures. Receptive vocabulary predicted rhyme identification. Syllable matching was predicted by a task tapping accuracy of phonological representations. The fact that rhyme identification was predicted by vocabulary knowledge but syllable matching was predicted by a measure tapping accuracy of phonological representations in both groups suggests that early lexical development sets the stage for the development of the lower levels of phonological sensitivity but identification of smaller units requires more accurate and segmented phonological representations.

    Very few studies have examined predictors of suicidal ideation among African American women. Consequently, we have a poor understanding of the combinations of culturally-specific experiences and psychosocial processes that may constitute risk and protective factors for suicide in this population. Drawing on theories of social inequality, medical sociology, and the stress process, we explore the adverse impact of gendered racism experiences and potential moderating factors in a sample of 204 predominantly low-SES African American women. We find that African American women’s risk for suicidal ideation is linked to stressors occurring as a function of their distinct social location at the intersection of gender and race. In addition, we find that gendered racism has no effect on suicidal ideation among women with moderate levels of well-being, self-esteem, and active coping, but has a strong adverse influence in those with high and low levels of psychosocial resources.

  4. SES Gradients Among Mexicans in the United States and in Mexico: A New Twist to the Hispanic Paradox?

    2016-10-01

    Recent empirical findings have suggested the existence of a twist in the Hispanic paradox, in which Mexican and other Hispanic foreign-born migrants living in the United States experience shallower socioeconomic status (SES) health disparities than those in the U.S. In this article, we seek to replicate this finding and test conjectures that could explain this new observed phenomenon using objective indicators of adult health by educational attainment in several groups: (1) Mexican-born individuals living in Mexico and in the United States, (2) U.S.-born Mexican Americans, and (3) non-Hispanic American whites. Our analytical strategy improves upon previous research on three fronts. First, we derive four hypotheses from a general framework that has also been used to explain the standard Hispanic paradox. Second, we study biomarkers rather than self-reported health and related conditions. Third, we use a binational data platform that includes both Mexicans living in Mexico (Mexican National Health and Nutrition Survey 2006) and Mexican migrants to the United States (NHANES 1999-2010). We find steep education gradients among Mexicans living in Mexico's urban areas in five of six biomarkers of metabolic syndrome (MetS) and in the overall MetS score. Mexican migrants living in the United States experience similar patterns to Mexicans living in Mexico in glucose and obesity biomarkers. These results are inconsistent with previous findings, suggesting that Mexican migrants in the United States experience significantly attenuated health gradients relative to the non-Hispanic white U.S. Our empirical evidence also contradicts the idea that SES-health gradients in Mexico are shallower than those in the United States and could be invoked to explain shallower gradients among Mexicans living in the United States.

    Full Text Available Abstract This study intends to give recommendations to the management of Paraty fishery in Brazil through an interplay of local and scientific knowledge. In particular, the objectives are the following: 1 to describe the Paraty fishery; 2 to compare the fishermen’s local ecological knowledge with recorded fish landings and previous studies in Paraty; 3 to combine the data on local fishing and on local/Caiçara livelihoods with the SES (social-ecological systems Model. The methods include a systematic survey of fishing in Tarituba and Praia Grande, which are located in the northern end and the central part of the Paraty municipality, respectively. For four days each month, systematic data on catches at landing points were collected, as well as macroscopic gonad analysis data for the fishes Centropomus parallelus and C. undecimalis (snook, robalo, Epinephelus marginatus (grouper, garoupa, Scomberomorus cavalla (King mackerel, cavala, and Lutjanus synagris (Lane snapper, vermelho. Spring and summer are important seasons during which some species reproduce, and the integration of fishing periods for some target species could assist in fishing management through the use of closed seasons. Fishermen could obtain complementary earnings from tourism and from the “defeso system” (closed season including a salary payment to conserve fishing stocks. The SES model facilitates an understanding of the historical context of fishing, its economic importance for local livelihoods, the constraints from conservation measures that affect fishermen, and the management processes that already exist, such as the defeso. If used to integrate fishing with complementary activities (tourism, such a system could improve the responsibility of fishermen regarding the conservation of fish stocks.

    This study investigated the contribution of child characteristics and parenting environment to the relationship between family SES/demographic characteristics and maternal language to infants.1157 children were drawn from a representative sample of 1292 infants born to mothers in rural Appalachian counties and rural counties in southern minority U.S. communities. Mothers and their 6-8 month old babies were videotaped at home while talking about a wordless picture book. Mothers' language output and complexity were analyzed. Child temperament, age, and parenting environment (knowledge of child development and observed mother-child engagement) were predictors of maternal language. Furthermore, their inclusion reduced the magnitude of the association between demographic characteristics and maternal language. Tests of mediation suggested that the parenting environment partially mediates the relationship between SES/demographic characteristics and maternal language. Findings are discussed with respect to identifying proximal processes that explain how SES may exert its influence on the language of young children.

    Full Text Available The paper contributes to the social-ecological systems literature byadapting and using Elinor Ostrom’s Social-Ecological System (SES frameworkin the context of a coastal ecosystem. We modified the SES framework in thecase of the Ciénaga Grande de Santa Marta (CGSM, an estuarine lagoon inthe Caribbean coast of Colombia. The ecological importance of CGSM and itsspecies is undeniable. This paper aims to understand why collective action fora sustainable use of CGSM’s fishery resources has not taken place. In order torespond to that question, we created new variables within the social, economic,and political settings of the SES framework. The results show that the fishers’ fearof the indiscriminate and strong violence that illegal armed groups have inflictedon them since the 1960s and the economic development in the ColombianCaribbean region help explain the lack of collective action.

    Full Text Available Background: Central nervous system (CNS infections present a grave health care challenge due to high morbidity and mortality. Clinical findings and conventional laboratory assessments are not sufficiently distinct for specific etiologic diagnosis. Identification of pathogens is a key to appropriate therapy. Aim: In this retrospective observational study, we evaluated the efficacy and clinical utility of syndrome evaluation system (SES for diagnosing clinically suspected CNS infections. Materials and Methods: This retrospective analysis included inpatients in our tertiary level neurointensive care unit (NICU and ward from February 2010 to December 2013. Cerebrospinal fluid (CSF samples of 70 patients, clinically suspected of having CNS infections, were subjected to routine laboratory tests, culture, imaging, and SES. We analyzed the efficacy of SES in the diagnosis of CNS infections and its utility in therapeutic decision-making. Results: SES had a clinical sensitivity of 57.4% and clinical specificity of 95.6%. Streptococcus pneumoniae and Pseudomonas aeruginosa were the top two bacterial pathogens, whereas Herpes simplex virus (HSV was the most common viral pathogen. Polymicrobial infections were detected in 32.14% of SES-positive cases. SES elicited a change in the management in 30% of the patients from initial empiric therapy. At discharge, 51 patients recovered fully while 11 patients had partial recovery. Three-month follow-up showed only six patients to have neurological deficits. Conclusion: In a tertiary care center, etiological microbial diagnosis is central to appropriate therapy and outcomes. Sensitive and accurate multiplex molecular diagnostics play a critical role in not only identifying the causative pathogen but also in helping clinicians to institute appropriate therapy, reduce overuse of antimicrobials, and ensure superior clinical outcomes.

    Full Text Available RESUMO Diante da importância da taxa de câmbio no comércio externo, considerando que suas flutuações podem modificar a escala de preços entre os países, a presente pesquisa buscou identificar o impacto da volatilidade da taxa de câmbio real bilateral sobre o fluxo de comércio entre os países da América do Sul. Para tal, foi estimado um modelo gravitacional utilizando uma amostra de nove países, entre 1998 e 2012. O método utilizado na estimação foi o modelo Poisson-Pseudo Maximum Likehood (PPML. Os resultados mostraram que a instabilidade cambial é prejudicial à relação de comércio entre países da América do Sul, já que maior incerteza cambial leva os agentes econômicos, a longo prazo, a reduzir suas atividades no comércio internacional, dada maior exposição ao risco. Outro resultado importante foi a constatação de que os países membros do Mercosul, de fato, têm o comércio favorecido diante das vantagens oferecidas pelo bloco, como a redução de tarifas comerciais. Quanto à variável utilizada para captar o efeito da crise do subprime em 2008, verificou-se aumento no fluxo comercializado pelos países sul-americanos nesse período.

    The current study explores the influence of socioeconomic status (SES) and bilingualism on the linguistic skills and verbal short-term memory of preschool children. In previous studies comparing children of low and mid-high SES, the terms “a child with low-SES” and “a child speaking a minority language” are often interchangeable, not enabling differentiated evaluation of these two variables. The present study controls for this confluence by testing children born and residing in the same count...

    In this thesis, we study fractures from borehole data on two sites: in one, located at Soultz-sous-Forets (Alsace) in the Rhine graben, boreholes reach a delta Jurassic series forming a petroleum reservoir. At Soultz, fractures have been studied on cores and borehole images. Striated faults present on cores permit to determine the tectonic history of the granite, completed by field study in Vosges Massif. This history corresponds to the Rhine graben history knowing by different authors. The analysis of vertical induced fractures observed on borehole images indicates a present-day NW-SE to NNW-SSE compression. These variations of stress direction are confirmed by others in situ measurements, as hydraulic injection, micro-seismicity, etc... On cores and borehole images, numerous fractures have been observed. Most of them are linked to the E-W distension, which permits the Rhine graben opening at Oligocene. At greatest scale, in quartz minerals, the micro-fractures are constitute by fluid inclusion trails. Several sets are related to the E-W distension, but others sets are linked to compressive stages. These sets are not observed on cores. This is a under-sampling of some fractures by the boreholes, but theses fractures exit into to rock massif. On borehole images, fracture density is weakest than the cores, however the set organisation is the same. At Ravenscar, the distribution of fracture spacing along different unidirectional sampling shows a exponential negative law. However, the fracture density varies with sampling. (author) 199 refs.

    Full Text Available Diferentes estratégias de proteção social têm sido utilizadas no mundo visando combater a fome e promover a mobilidade social. Dentre elas, os programas de transferência condicionada de renda têm se destacado pelo desenho contratual e pela estrutura de governança que tem a promoção do comportamento positivo do indivíduo, e não a assistência, como elemento central. Portanto, famílias que participam desses programas recebem, em geral, determinada quantia financeira destinada a satisfazer as necessidades básicas e contribuir para o atendimento das condições positivas impostas à sua manutenção no programa. Conhecer as condicionalidades e perceber sob qual contexto de investigação essas práticas têm sido abordadas no meio acadêmico torna-se fator de relevância científica e social. Nessa direção, este trabalho teve como propósito discutir os diferentes desenhos dessa política em diversos países. Para tanto, 50 trabalhos científicos, distribuídos por 28 países, foram analisados, visando contextualizar metodologias e resultados alcançados. Para realizar tal análise, foi procedido um estudo exploratório, a partir da técnica de metaestudo, utilizando como referência a base de dados do Banco Mundial, sítios eletrônicos e artigos sobre o assunto, publicados entre 2003 e 2011, com a finalidade perceber sob qual ótica têm sido estudados os principais programas de transferência de renda do mundo. Dentre os principais resultados alcançados, merece destaque o fato de, indiferentemente do país ou programa de transferência considerado, a manutenção das crianças na escola e o cuidado com a saúde infantil são condições centrais de inclusão e manutenção da família no sistema de transferência.

  18. Contribution of the Surface and Down-Hole Seismic Networks to the Location of Earthquakes at the Soultz-sous-Forêts Geothermal Site (France)

    Seismicity induced in geo-reservoirs can be a valuable observation to image fractured reservoirs, to characterize hydrological properties, or to mitigate seismic hazard. However, this requires accurate location of the seismicity, which is nowadays an important seismological task in reservoir engineering. The earthquake location (determination of the hypocentres) depends on the model used to represent the medium in which the seismic waves propagate and on the seismic monitoring network. In this work, location uncertainties and location inaccuracies are modeled to investigate the impact of several parameters on the determination of the hypocentres: the picking uncertainty, the numerical precision of picked arrival times, a velocity perturbation and the seismic network configuration. The method is applied to the geothermal site of Soultz-sous-Forêts, which is located in the Upper Rhine Graben (France) and which was subject to detailed scientific investigations. We focus on a massive water injection performed in the year 2000 to enhance the productivity of the well GPK2 in the granitic basement, at approximately 5 km depth, and which induced more than 7000 earthquakes recorded by down-hole and surface seismic networks. We compare the location errors obtained from the joint or the separate use of the down-hole and surface networks. Besides the quantification of location uncertainties caused by picking uncertainties, the impact of the numerical precision of the picked arrival times as provided in a reference catalogue is investigated. The velocity model is also modified to mimic possible effects of a massive water injection and to evaluate its impact on earthquake hypocentres. It is shown that the use of the down-hole network in addition to the surface network provides smaller location uncertainties but can also lead to larger inaccuracies. Hence, location uncertainties would not be well representative of the location errors and interpretation of the seismicity

    In this paper, a new formulation of the spatial dependent impulse response of a subcritical reactor in a cylindrical geometry is proposed. An expression of the transfer function between a point source at the center of coordinates and the flux at a given point (r,z) is obtained by solving: by means of Laplace transform, the one group diffusion equation. In this transfer function, variables r and p (p being the Laplace variable) remain linked within a modified Bessel function. Taking the inverse Laplace transform is done by two different ways: - using the Mellin-Fourier method which separates variables r and t. This method makes it possible to establish that there is identity between the classical formulation and the new one. - using an inverse Laplace transform which keeps variables r and t linked. This method requires to approximate the inverse Laplace transform of the end factor. It is then possible to replace the radial harmonics modes series of the classical expression by a single function. This new formulation seems to be of particular interest when dealing with reactors of large size and lifetime. It is also interesting each time the harmonics play an important role. (author) [French] Dans le present rapport, on propose une nouvelle formulation de la reponse impulsionnelle spatio-temporelle d'un reacteur sous-critique, en geometrie cylindrique. Une expression de la fonction de transfert entre une source ponctuelle placee au centre des coordonnees et le flux au point courant (r,z) est obtenue en resolvant, par transformation de Laplace, l'equation de la diffusion a un seul groupe d'energie. Dans cette fonction de transfert, les variables r et p (variable de Laplace) demeurent groupees dans une fonction de Bessel modifiee. Le retour a l'original est effectue de deux manieres: - la methode de Mellin-Fourier qui separe les variables r et t, permet d'etablir l'identite entre la nouvelle formulation et la formulation classique. - un original conservant les variables

  20. Numerical modeling of the impact of temperature on the behavior of minerals in the Soultz-sous-Forêts enhanced geothermal system

    Operation of the enhanced geothermal system (EGS) requires to re-inject fluid, after heat exchange at the surface to the energy production, into the geothermal reservoir. This cold re-injected fluid can cause a strong disequilibrium with the fluid and granitic rock within the geothermal reservoir and then implies the possible dissolution/precipitation of minerals. The hydrothermal alterations include the transformation of plagioclase, biotite and K-feldspar and the precipitation of various secondary minerals. The major sealing phases observed in the main fracture zones are quartz, calcite, and clay minerals. These mineralogical transformations may modify the porosity, permeability and fluid pathways of the geothermal reservoir. In the Soultz-sous-Forêts EGS (Alsace, France), the hydraulic connection between the injection well and the production well is quite poor. Therefore, understanding the impact of changes in temperature, which are caused by the re-injected fluid, on the behavior of minerals (especially for the main newly-formed minerals such as quartz, calcite and clay minerals) is a critical preliminary step for the long-term prediction of their evolution. The approach used in the present work is typically based on a geochemical code, called THERMA, which enables to calculate the changes in equilibrium constants of all primary and secondary minerals and aqueous species as a function of temperature. Our model accounted for a wide range of different mineral groups in order to make sure a large freedom for the numerical calculations. The modeling results showed that when the temperature of geothermal reservoir is cooled down, quartz, calcite, illites, galena and pyrite have tendency towards equilibrium state, which indicates that they are precipitated under the geothermal conditions. In contrast, other minerals including plagioclase, K-feldspar and biotite remained unsaturated. These behaviors of minerals were further illustrated by the Khorzinsky stability

    After having developed one of the first thermo-balances to operate under pressure, we have studied the influence of the pressure on the corrosion of iron and steels by carbon dioxide. The corrosion was followed by three different methods simultaneously: by the oxidation kinetics, by micrographs, and by radiocrystallography. We have been able to show that the influence of the pressure is not negligible and we have provided much experimental evidence: oxidation kinetics, micrographic aspects, surface precipitation of carbon, metal carburization, the texture of the magnetite layer. All these phenomena are certainly modified by changes in the carbon dioxide pressure. In order to interpret most of our results we have been led to believe that the phenomenon of corrosion by CO{sub 2} depends on secondary reactions localised at the oxide-gas interface. This would constitute a major difference between the oxidation by CO{sub 2} and that by oxygen. (author) [French] Apres avoir etudie et mis au point une des premieres thermobalances fonctionnant sous pression, nous avons etudie l'influence de la pression sur la corrosion du fer et des aciers par l'anhydride carbonique.

Tous ces phenomenes sont sans aucun doute modifies par une variation de pression du gaz carbonique. Pour interpreter la plupart de nos resultats, nous avons ete conduits a penser que le phenomene de corrosion par CO{sub 2} etait tributaire de reactions secondaires localisees a l'interface oxyde-gaz. Ce serait la une des differences fondamentales entre l'oxydation par

    This work on the compatibility of magnesium alloys with pressurized carbon dioxide has been carried out along three lines: - testing of special alloys containing additions of zirconium, manganese, cerium, zinc, beryllium and yttrium. The results are satisfactory, generally speaking, and the corrosion kinetics are often comparable to those of conventional magnesium-zirconium alloy; - influence of the quality of the carbon dioxide, in particular the presence of water vapour or of carbon monoxide in this gas. It appears that oxidation is reduced if the carbon dioxide contains traces of water vapour, but is more pronounced if carbon monoxide is also present; - study of certain phenomena related to corrosion: size changes in the samples during tests, structural modifications in the alloys (grain-size changes, formation of a cortical zone in the case of alloys containing zirconium). The influence of thermal cycling has also been studied in a few specific tests. The results obtained make it possible to compare the behaviour of various alloys under varying conditions of long-term use, and to choose, if required, the best composition for a given application. (authors) [French] Ce travail sur la compatibilite des alliages de magnesium avec le gaz carbonique sous pression a ete particulierement oriente dans trois directions: - epreuve, d'alliages speciaux comportant des additions de zirconium, manganese, cerium, zinc, beryllium et yttrium.

    The alignment of grains in isostatically precompacted samples of prereacted Bi{1,8}Pb{0,4}Sr{2,0}Ca{2,2}Cu{3,0}O{10,3 + x} powder has been achieved by compressive plastic deformation under isostatic pressure at room temperature. Isostatic pressures were in the range 0.1 to 1 GPa and deformation rates were led up to 57 %. Prior to sintering, X-ray diffraction measurements corroborate an expected high- T_c phase purity of nearly 85 % and indicate that the as-deformed samples have been textured with the (c-axes parallel to the pressing direction whilst a.c. susceptibility measurements ascertain a high transition temperature around 107 K. Intergranular connection does not occur until sintering at 850 ^{circ}C for 80 h and measurements indicate then that the texture has been retained. Superconducting properties themselves show sensitivity to texture through anisotropy-related distinctive irreversibility lines. L'alignement de grains de poudre Bi{1,8}Pb{0,4}Sr{2,0}Ca{2,2}Cu{3,0}O{10,3 + x} préréagie a été réalisé par déformation plastique à température ambiante d'échantillons précompactés isostatiquement et comprimés sous pression isostatique, la gamme des pressions isostatiques allant de 0,1 à 1 GPa et les taux de déformation atteignant 57 %. Les mesures de diffraction de rayons X corroborent la pureté de phase à haute T_c proche de 85 % attendue et indiquent que les échantillons ainsi déformés ont été texturés avec les plans ab perpendiculaires à la direction de compression. Les mesures de susceptibilité alternative avèrent une température élevée de transition à environ 107 K mais la connexion intergranulaire n'est assurée qu'après un frittage à 850 ^{circ}C pendant 80 h dont on vérifie qu'il conserve la texture. Enfin, la sensibilité des propriétés supraconductrices à la texturation est évaluée par le biais de lignes d'irréversibilité distinctes en fonction de l'anisotropie.

    Full Text Available The egcSEs comprise five genetically linked staphylococcal enterotoxins, SEG, SEI, SElM, SElN and SElO and two pseudotoxins which constitute an operon present in up to 80% of Staphylococcus aureus isolates. A preparation containing theses proteins was recently used to treat advanced lung cancer with pleural effusion. We investigated the hypothesis that egcSEs induce nitrous oxide (NO and associated cytokine production and that these agents may be involved in tumoricidal effects against a broad panel of clinically relevant human tumor cells. Preliminary studies showed that egcSEs and SEA activated T cells (range: 11-25% in a concentration dependent manner. Peripheral blood mononuclear cells (PBMCs stimulated with equimolar quantities of egcSEs expressed NO synthase and generated robust levels of nitrite (range: 200-250 µM, a breakdown product of NO; this reaction was inhibited by NG-monomethyl-L-arginine (L-NMMA (0.3 mM, an NO synthase antagonist. Cell free supernatants (CSFs of all egcSE-stimulated PBMCs were also equally effective in inducing concentration dependent tumor cell apoptosis in a broad panel of human tumor cells. The latter effect was due in part to the generation of NO and TNF-α since it was significantly abolished by L-NMMA, anti-TNF-α antibodies respectively and a combination thereof. A hierarchy of tumor cell sensitivity to these CFSs was as follows: lung carcinoma>osteogenic sarcoma>melanoma>breast carcinoma>neuroblastoma. Notably, SEG induced robust activation of NO/TNFα-dependent tumor cell apoptosis comparable to the other egcSEs and SEA despite TNF-α and IFN-γ levels that were 2 and 8 fold lower respectively than the other egcSEs and SEA. Thus, egcSEs produced by S. aureus induce NO synthase and the increased NO formation together with TNF-α appear to contribute to egcSE-mediated apoptosis against a broad panel of human tumor cells.

  10. What factors help or hinder the achievement of low SES students? An international comparison using TIMSS 2011 8th grade science data

    Bruner, Justin L.

    Focusing on science from a cross-country perspective, this study explores the relationship between 8th grade science achievement and student, teacher, and school characteristics. More specifically, this study will pay special attention to low socio-economic status (SES) students and seek to understand why some disadvantaged students are able to have higher than expected achievement in science given their SES while other disadvantaged students are not able to achieve beyond what would be expected given their background. This study will explore the multi-level relationship between the characteristics of students, their teachers, their schools, and student achievement in science. While looking at students in classrooms and in schools, this work will create as precise as possible a measure of student SES by drawing on recommendations of an expert panel commissioned by the National Association of Educational Progress (NAEP) study. The study uses the most recent cycle (2011) of the Trends in International Math and Science Study (TIMSS), to strategically select a six-country sample from the 45 participating countries. This six-country sample was selected by using the country level achievement and the standard deviation of that achievement. This will create a sample that has a range of equality in achievement and strength in achievement. This allows for making comparisons both across and within countries to better understand variations in the factors of student performance, especially for disadvantaged students. This paper builds on the existing research around socio-economic status (SES) and achievement by exploring in more detail the conditions in schools and classrooms around the world that might magnify or reduce the effect of SES on student achievement. The analysis looks at these questions: "What conditions help low SES students achieve higher than what would be expected given their SES?" and "What conditions hinder low SES students to achieve at or below what would

    First, the point of applying Dynamic Programming to optimization and Operational Research problems in chemical industries are recalled, as well as the conditions in which a dynamic program is illustrated by a sequential graph. A new algorithm for the determination of sub-optimal politics in a sequential graph is then developed. Finally, the applications of sub-optimality concept is shown when taking into account the indirect effects related to possible strategies, or in the case of stochastic choices and of problems of the siting of plants... application examples are given.

    Full Text Available Las actuales modificaciones en el mundo del trabajo y en especial en las instituciones universitarias, han puesto de manifiesto nuevos riesgos de orden psicosocial que impactan no solo la salud física sino también la salud mental de los docentes, derivándose en el conocido síndrome de burnout. Se identificaron algunos factores de riesgo psicosocial intralaboral que propician el desarrollo y prevalencia del síndrome de burnout en estos profesionales de algunos países de América Latina como Colombia, Venezuela, Argentina y México. Se concluyó que ciertos aspectos propios de la organización del trabajo y de su realización tales como: multiplicidad de tareas, sobrecarga laboral, espacios inadecuados, falta de tiempo y de remuneración que compense los esfuerzos, son algunas de las principales fuentes de riesgos psicosociales que coadyuvan al posterior desarrollo y prevalencia del síndrome en esta población.

A través de un análisis de frontera estocástica se estima la eficiencia para probar si la aglomeración contribuye a acercar más a su frontera de productividad eficiente. Se emplea una función de producción translogarítmica, porque permite cambios tecnológicos y variaciones en las proporciones de insumos y productos de la elasticidad de escala. Los resultados muestran que en el sector manufacturero no se generaron ni mejoramientos en la eficiencia técnica ni cambios tecnológicos durante los catorce años. La evidencia sugiere que las variables ambientales determinadas por la formación bruta de capital fijo total o solo en maquinaria y equipo influyen en el comportamiento del sector.

    Full Text Available Abstract Background Research has shown inconsistencies in results and difficulties in conceptualization of assessment of socioeconomic status (SES among adolescents. The aim of this study was thus to test the validity of self-reported information on SES in two age-groups (11–13 and 14–16 years old in an adolescent population and to evaluate its relationship to self-reported health related quality of life (HRQOL. Different measures of SES commonly used in research in relation to HRQOL were tested in this study; parent’s occupations status, family material affluence status (FAS and perceived SES. Method A cross-sectional study, with a sample of 948 respondents (n = 467, 11–13 years old and n = 481, 14–16 years old completed questionnaires about SES and HRQOL. The adolescents’ completion rates were used, with chi2-test, to investigate differences between gender and age-group. Correlation was used for convergent validity and ANOVA for concurrent validity. Results We found a low completion rate for both fathers’ (41.7 % and mothers' (37.5 % occupation status, and a difference in completion rate between gender and age-groups. FAS had the highest completion rate (100 % compared to parent's occupations status and perceived SES. The convergent validity between the SES-indicators was weak (Spearman correlation coefficient below 0.3, suggesting that the indicators measured different dimensions of SES. Both FAS and perceived SES showed a gradient in mean HRQOL between low and high SES in relation to HRQOL, this was significant only for perceived SES (p < 0.01, both age-groups. Conclusion This study indicates the need for considering different approaches to measures of SES among adolescences and when evaluating SES in relation to HRQOL. Further research is needed to investigate sustainable ways to measure SES, delineating the relevance of tangible measures of education, occupation and income in relation to the perceived

    Full Text Available O objetivo deste ensaio é explorar o tema da desigualdade econômica a partir das distribuições de renda disponível e de patrimônio nos países desenvolvidos e, de modo mais detalhado, nos Estados Unidos. A análise explora o aumento da desigualdade enquanto resultado das transformações da sociedade capitalista ocorridas nos últimos quase 40 anos, que provocaram uma desvalorização dos salários acompanhada de uma maior financeirização da renda associada à dinâmica da riqueza, isto é, do patrimônio detido por certas parcelas das populações desses países. Ele adota uma perspectiva de análise de natureza estrutural, entendendo que o aumento da desigualdade que a crise atual poderá carregar deve ser visto como parte do processo de sua ampliação produzida pelas transformações ocorridas na sociedade capitalista desenvolvida ao longo dos últimos quase 40 anos. Nestes últimos 40 anos, o capitalismo desenvolvido conheceu um processo de sistemática reorganização econômica, social e política de suas estruturas produtivas, das instituições de representação e regulação e da dinâmica da acumulação de capital. A desigualdade deve ser entendida como transformação, que teve a financeirização como instrumento relevante para a modificação da distribuição de renda.This essay debates the theme of economic inequality from the distribution of disposable income and wealth in developed countries and especially in the United States. The analysis explores the increase in inequality as a result of the transformation of capitalist society have occurred over the past forty years, which led to a devaluation of wages accompanied by greater financialization of income linked to the dynamics of wealth, i.e. the assets held by certain portions of the populations these countries. It adopts an analytical perspective of structural nature, meaning that the increase in inequality that can load the current crisis should be seen as part of

    Full Text Available La evidencia acumulada sobre el efecto de crisis anteriores en la salud presenta patrones muy diferenciados atribuibles al diseño de los estudios, a la naturaleza de cada crisis y a otros factores del entorno socioeconómico y político. Existe, no obstante, un consenso cada vez mayor sobre el papel mediador de las respuestas políticas de los gobiernos, que pueden magnificar, o al contrario mitigar, los efectos adversos de las crisis. Estudios recientes revelan un deterioro en algunos indicadores de salud en el contexto de la crisis actual, fundamentalmente en salud mental y enfermedades transmisibles. En algunos países europeos también se ha constatado un descenso en el consumo de tabaco y alcohol. Por otro lado, algunos gobiernos están haciendo uso del contexto de crisis para avanzar reformas tendentes a la privatización de servicios y prestaciones sanitarias, restringiendo con ello el derecho a la salud y a la atención sanitaria. Se está actuando sobre los tres ejes que determinan el campo de la financiación de los sistemas sanitarios: la población protegida, la contribución del usuario y la cobertura de servicios. Estas medidas están siendo adoptadas a menudo de manera arbitraria basándose en decisiones ideológicas más que en la evidencia disponible, de lo que cabría esperar consecuencias adversas en términos de protección financiera, eficiencia y equidad.

Es una investigación documental-analítica, fundamentada en una revisión bibliográfica y en la clasificación del material para el procesamiento de los datos recolectados, la interpretación de esos datos parte de la categoría crisis del ciclo neoliberal. El neoliberalismo reduce las funciones de los Estados andinos a las áreas medulares: educación, salud y seguridad ciudadana, privatiza las empresas estatales y los servicios públicos, donde la ¿razón del mercado¿ priva la relación Sociedad-Estado, con consecuencias nefastas para la población, originando en el tiempo el surgimiento democrático de gobiernos anti-neoliberales. Se concluye que en los albores del siglo XXI el neoliberalismo entra en crisis, cuando el mercado manifiesta su incapacidad de contrarrestar los altos índices de pobreza y el deterioro de las condiciones vida de los ¿pueblos¿, los gobiernos andinos de izquierda introducen cambios en los sistemas políticos, redimensionando las políticas de ajuste macro-económico y rechazan los acuerdos bilaterales y multilaterales promotores de libre mercado en el seno del sistema institucional de integración andina.

La formation du Ge mesoporeux par gravure electrochimique a ete precedemment rapportee dans la litterature. Cependant, le verrou technologique important des procedes de fabrication existants consistait a obtenir des couches epaisses (superieure a 500 nm) du Ge mesoporeux a la morphologie parfaitement controlee. En effet, la caracterisation physico-chimique des couches minces est beaucoup plus compliquee et le nombre de leurs applications possibles est fortement limite. Nous avons developpe un modele electrochimique qui decrit les mecanismes principaux de formation des pores ce qui nous a permis de realiser des structures epaisses du Ge mesoporeux (jusqu'au 10 mum) ayant la porosite ajustable dans une large gamme de 15% a 60%. En plus, la formation des nanostructures poreuses aux morphologies variables et bien controlees est desormais devenue possible. Enfin, la maitrise de tous ces parametres a ouvert la voie extremement prometteuse vers la realisation des structures poreuses a multi-couches a base de Ge pour des nombreuses applications innovantes et multidisciplinaires grace a la flexibilite technologique actuelle atteinte. En particulier, dans le cadre de cette these, les couches du Ge mesoporeux ont ete optimisees dans le but de realiser le procede de transfert de couches minces d'une cellule solaire a triple jonctions via une couche sacrificielle en Ge poreux.

    Studies conducted in developing countries have noted associations between concurrent stunting, social-emotional problems and poor cognitive ability in young children. However, the relative contribution of these variables in Latin America is likely changing as undernutrition rates decline and prevalence of childhood obesity rises. We conducted a cross-sectional study of 106 normal-weight and 109 obese preschool children to compare the relative contribution of early nutrition, sociodemographic factors and psychosocial variables on cognitive development in normal-weight and obese preschool children in Chile. The study variables were categorized as: (1) socio-demographic (age, sex, birth order and socioeconomic) (2) early nutrition (maternal height, birth weight, birth length and height at 5 years) (3) psychosocial factors (maternal depression, social-emotional wellbeing and home space sufficiency). In order to assess determinants of cognitive development at 4-5 years we measured intelligence quotient (IQ); variability in normal children was mostly explained by socio-demographic characteristics (r(2) = 0.26), while in obese children early nutritional factors had a significant effect (r(2) = 0.12) beyond socio-demographic factors (r(2) = 0.19). Normal-weight children, who were first born, of slightly better SES and height Z score >1, had an IQ ≥ 6 points greater than their counterparts (p birth weight >4,000 g and low risk of socio-emotional problems had on average ≥5 IQ points greater than their peers (p < 0.05). We conclude that in Chile, a post-transitional country, IQ variability of normal children was mostly explained by socio-demographic characteristics; while in obese children, early nutrition also played a significant role.

    The ability to predict spectral electro-optical (EO) signatures for various targets against realistic, cluttered backgrounds is paramount for rigorous signature evaluation. Knowledge of background and target signatures, including plumes, is essential for a variety of scientific and defense-related applications including contrast analysis, camouflage development, automatic target recognition (ATR) algorithm development and scene material classification. The capability to simulate any desired mission scenario with forecast or historical weather is a tremendous asset for defense agencies, serving as a complement to (or substitute for) target and background signature measurement campaigns. In this paper, a systematic process for the physical temperature and visible-through-infrared radiance prediction of several diverse targets in a cluttered natural environment scene is presented. The ability of a virtual airborne sensor platform to detect and differentiate targets from a cluttered background, from a variety of sensor perspectives and across numerous wavelengths in differing atmospheric conditions, is considered. The process described utilizes the thermal and radiance simulation software MuSES and provides a repeatable, accurate approach for analyzing wavelength-dependent background and target (including plume) signatures in multiple band-integrated wavebands (multispectral) or hyperspectrally. The engineering workflow required to combine 3D geometric descriptions, thermal material properties, natural weather boundary conditions, all modes of heat transfer and spectral surface properties is summarized. This procedure includes geometric scene creation, material and optical property attribution, and transient physical temperature prediction. Radiance renderings, based on ray-tracing and the Sandford-Robertson BRDF model, are coupled with MODTRAN for the inclusion of atmospheric effects. This virtual hyperspectral/multispectral radiance prediction methodology has been

    Full Text Available The recent tomography results obtained within the scope of the Enhanced Geothermal System (EGS European Soultz project led us to revisit the meso-fracturing properties of Soultz test site. In this paper, we develop a novel approach coupling effective medium modeling and shear-wave splitting to characterize the evolution of crack properties throughout the hydraulic stimulation process. The stimulation experiment performed in 2000 consisted of 3 successive injection steps spanning over 6 days. An accurate 4-D tomographic image was first carried out based upon the travel-times measured for the induced seismicity [Calò M., Dorbath C., Cornet F.H., Cuenot N. (2011 Large-scale aseismic motion identified through 4-D P-wave tomography, Geophys. J. Int. 186, 1295-1314]. The current study shows how to take advantage of the resulting compressional wave (Calò et al., 2011 and shear-wave velocity models. These are given as input data to an anisotropic effective medium model and converted into crack properties. In short, the effective medium model aims to estimate the impact of cracks on velocities. It refers to a crack-free matrix and 2 families of penny-shaped cracks with orientations in agreement with the main observed geological features: North-South strike and dip of 65°East and 65°West [Genter A., Traineau H. (1996 Analysis of macroscopic fractures in granite in the HDR geothermal well EPS-1, Soultz-sous-Forêts, France, J. Vol. Geoth. Res. 72, 121-141], respectively. The resulting output data are the spatial distributions of crack features (lengths and apertures within the 3-D geological formation. We point out that a flow rate increase results in a crack shortening in the area imaged by both compressional and shear waves, especially in the upper part of the reservoir. Conversely, the crack length, estimated during continuous injection rate phases, is higher than during the increasing injection rate phases. A possible explanation for this is that

Ils montrent qu'on peut etablir un rapport entre la constante de decroissance du mode fondamental des neutrons instantanes et le facteur de multiplication effectif du systeme en fonction de deux parametres qui ont ete definis, aux fins du present memoire, comme le coefficient de reponse du reacteur et le facteur de correction pour la decroissance des neutrons instantanes et qui dependent dans une large mesure des structures de flux spatiales a l'interieur du systeme. Pour le systeme uniforme sans reflecteur, le coefficient de reponse peut etre considere comme etant identique a la duree de vie moyenne des neutrons dans le systeme; pour un systeme a plusieurs regions, c'est une moyenne des durees de vie dans toutes les regions ponderees par des integrales du type a perturbation. Le deuxieme parametre - le facteur de correction pour la decroissance - ne peut avoir aucune signification physique, en ce sens qu'il ressort d'une tentative faite pour etablir une relation entre les deux echelles de reactivite, savoir l'echelle que l'on obtient en utilisant la constante de decroissance des neutrons instantanes et celle que l'on obtient en utilisant le facteur de multiplication effectif. Les auteurs etudient les proprietes de ces parametres en se referant a un reacteur a uranium enrichi ralenti au graphite, qui se compose d'un coeur uniforme et d'un reflecteur; ils montrent que les deux parametres ne sont pas definis uniquement par la reactivite du systeme, mais dependent de la methode choisie pour rendre le systeme sous-critique.

    Full Text Available Comme la didactique est un domaine de réflexions sur les pratiques d’enseignement/apprentissage et en raison de la difficulté des scripteurs à se représenter un équilibre entre les connaissances et les attentes des lecteurs potentiels de leur écrit, nous analysons les effets d’une variante du travail collaboratif sur les procédés de réécriture mis en œuvre en situation de production écrite individuelle, et par hypothèse, sur les capacités cognitives de prise en charge du lecteur différé du message. Il s'agit précisément d’analyser les développements du contenu sémantique d'un texte descriptif en français langue étrangère, écrit et réécrit en situation individuelle, par des apprenants de première année licence de français, suite aux annotations mentionnées par les pairs. Le socioconstructivisme (Vygotsky; Jonnaert prône le rôle majeur des interactions sociales dans la construction et la reconstruction des connaissances. Les recherches sur la cognition soulignent le besoin de développer la responsabilité individuelle au niveau de la construction des connaissances.

    2010-07-01

    Full Text Available Este documento analiza cómo resolver el problema de la falta de acceso a los servicios financieros que padece la amplia mayoría de la población de los países en desarrollo. La solución propuesta toma como hipótesis que la falta de acceso a los servicios financieros se explica principalmente por un problema de oferta. Los modelos de negocio usados por las entidades financieras que operan en los países en desarrollo son inadecuados e ineficientes al no permitir servir rentablemente a los segmentos de bajos ingresos. Para resolver este problema de oferta, se necesita del desarrollo de modelos de negocio de distribución de servicios microfinancieros a bajo coste adaptados para servir a segmentos de población de bajos ingresos rentablemente.

    2012-12-01

    Full Text Available O presente artigo propõe analisar a questão energética entre os BRICS e o potencial de rearticulação da ordem energética global que dela emerge. Para tal, realiza três movimentos. Em primeiro lugar, investiga o crescente impacto agregado dos países BRICS no cenário energético global, com vistas a analisar seu avanço em uma temática até então reduto dos países desenvolvidos. Em segundo lugar, aborda a matriz energética de cada um dos cinco países do ponto de vista de suas economias políticas e da questão da sustentabilidade. Em terceiro lugar, e com base na seção anterior, propõe mapear as áreas de conflito e de possível aproximação entre os BRICS, na tentativa de localizar as possibilidades e limites da sua cooperação energética. Com base nessa investigação, conclui que, diante das potencialidades para a cooperação entre os países, a organização de suas ofertas e demandas energéticas nacionais pode permitir ao agrupamento articular-se como um novo polo no cenário energético global.

Retoma las grandes etapas históricas por las que ha transitado el agro en los países de América Latina en general y el MERCOSUR en particular. Luego, se revisan los rasgos centrales que tienen las actuales políticas rurales de los países miembros de MERCOSUR, en especial su manejo de las marcas y denominaciones de origen. No existe una política común de desarrollo rural; las políticas agrícolas nacionales son sólo sectoriales y se orientan a promover la productividad y la competitividad comprimiendo costos, por encima de la valorización de la calidad. Sin embargo, en la última década, Se está rescatando no sólo el entorno geográfico característico del medio rural, sino también se valorizan las formas de vida, alimentos, bienes y servicios, resultado de la identidad cultural de las poblaciones. Por último, se presentan dos iniciativas de valorización de la identidad cultural rural en Argentina: los Caminos de Altamira - San Carlos, Mendoza y El Vino de la Costa - Berisso, Buenos Aires.

    The paper gives a general review of some of the main technological features of apparatus, for instance spherical apparatus, for industrial radiochemical processes. A method is proposed for estimating the effectiveness of apparatus of any given construction by comparing it with the output of an infinitely large apparatus having the same radiation source. An account is given of the technological features of an apparatus for radio-polymerizing ethylene at 200 atmospheres and 25{sup o}C{sup 1} with a rodshaped gamma-radiation source (Co{sup 60}) of variable activity. This apparatus can be designed to suit the mean dose rate which the power efficiency of the apparatus allows. It is shown that the yield, Q, of the apparatus is, other things being equal, a constant ration of the power, W{sub 0}, of the gamma-radiation of the apparatus. In the apparatus reviewed, Q {approx} W{sub 0}{sup 0,5}.

    Full Text Available É compreensível que devido a relevância dos relatórios contábeis e sua maior importância com a adoção das IFRS haja nas empresas uma preocupação com os fatores que causam interferência na sua qualidade, bem como, com os critérios utilizados na sua formação, consistência e avaliação. Dentre os fatores que exercem influencia na qualidade das informações contábeis está o conservadorismo, definido por Basu (1997 como um reconhecimento assimétrico das perdas em relação aos ganhos, se refletem as más notícias mais rapidamente do que as boas notícias. Considerando este contexto, o presente estudo tem o objetivo de avaliar as magnitudes das influências das IFRS nos níveis de conservadorismo contábil das práticas adotadas nos países membros do GLENIF, mais especificadamente, Argentina, Brasil, Chile, Colômbia, México e Peru no período de 2003 a 2013. Com uma amostra de 513 empresas e 5643 observações, aplicou-se por meio de dados em painel a equação original de Basu (1997 e, posteriormente, incluiu-se uma variável dummy considerando os efeitos da adoção das IFRS no conservadorismo. Os resultados indicaram que, mesmo com a adoção das IFRS notou-se no Brasil e no México a presença de práticas conservadoristas. Na Argentina constatou-se situação contrária, as IFRS amenizaram o conservadorismo nas empresas do país. Já no Chile, Colômbia e Peru os resultados não significativos foram insuficientes para indicarem a presença de conservadorismo após a adoção das IFRS.

El desarrollo de la Enseñanza Uni versi taria atendiendo a estos parámetros permiten presentar a la uni versidad británica como modelo institucional actual frente al concepto, valores y la apuesta investigadora tradicionales característicos de la uni versidad humboldtiana alemana, reacia a los cambios que exige la embestida neoconservadora de la década de los noventa. De igual modo, dicho desarrollo revela la nueva función a la par inclusiva y de equ ilibrio de las enseñanzas que posee la universidad en el S. XXI frente a tradiciones predominantemente liberales del tipo de la universidad francesa, o a tradiciones de escasa diversificaci"ón curricular o de los programas, como ha sido el caso de la universidad española hasta años recientes.En líneas generales, si bien los rasgos estructura les y fomlales característicos de la Enseñanza Uni versitaria británica se revelan idóneos respecto al rol de la universidad en nuestros días, esta institución debe, al igual que la universidad en los restantes países europeos y en colaboración con los restantes agentes sociales, hallar el modo de lograr una estructura y organización curricular acordes con los nuevos debates presentes en la actualidad en las políticas de enseñanza universitaria y, muy especialmente. con el nuevo tipo de alumno asistente a la misma.

    Full Text Available Na medida em que a população mundial está envelhecendo, a demência está se constituindo em importante problema de saúde pública, particularmente nos países em desenvolvimento. Investigações epidemiológicas nestes países são escassas e apresentam dificuldades metodológicas adicionais, principalmente no que se refere à adequação sociocultural dos instrumentos utilizados para a definição de casos. Tendo em vista estas preocupações, foi fundado o "Grupo de Pesquisa em Demência 10/66", que é constituído por uma rede internacional de pesquisadores, predominantemente de países em desenvolvimento. O nome do grupo tem como referência o paradoxo de que menos de 10% dos estudos populacionais sobre demência são dirigidos aos 2/3 ou mais de casos de pessoas com demência que vivem em países em desenvolvimento. O objetivo do artigo é atualizar informações da literatura sobre as diferenças de prevalência e incidência de demência encontradas em países desenvolvidos e em desenvolvimento.As the world population is ageing, dementia becomes an important public health problem, particularly in developing countries. Epidemiological research in these settings is scarce and present additional methodological difficulties, mainly regarding the socio-cultural adequacy of instruments used to identify cases of dementia. As a result of these concerns the 10/66 Dementia Research Group was founded to fill this gap. This is an international network of investigators, mostly from developing countries, and the group's name was based on the paradox that less than 10% of the population-based studies on dementia are directed to 2/3 or more cases of people with dementia living in developing countries. The aim of the paper is to update data in the literature regarding the differences in dementia prevalence and incidence seen in developed and developing countries.

    2000-12-01

    Full Text Available This paper reviews the current knowledge of leishmaniasis epidemiology in Venezuela, Colombia, Ecuador, Peru, and Bolivia. In all 5 countries leishmaniasis is endemic in both the Andean highlands and the Amazon basin. The sandfly vectors belong to subgenera Helcocyrtomyia, Nyssomiya, Lutzomyia, and Psychodopygus, and the Verrucarum group. Most human infections are caused by Leishmania in the Viannia subgenus. Human Leishmania infections cause cutaneous lesions, with a minority of L. (Viannia infections leading to mucocutaneous leishmaniasis. Visceral leishmaniasis and diffuse cutaneous leishmaniasis are both rare. In each country a significant proportion of Leishmania transmission is in or around houses, often close to coffee or cacao plantations. Reservoir hosts for domestic transmission cycles are uncertain. The paper first addresses the burden of disease caused by leishmaniasis, focusing on both incidence rates and on the variability in symptoms. Such information should provide a rational basis for prioritizing control resources, and for selecting therapy regimes. Secondly, we describe the variation in transmission ecology, outlining those variables which might affect the prevention strategies. Finally, we look at the current control strategies and review the recent studies on control.Este trabalho revisa o conhecimento atual sobre a epidemiologia da leishmaniose na Venezuela, Colômbia, Equador, Peru e Bolívia, países nos quais a doença é endêmica, tanto nos Andes quanto na Amazônia.

En Côte d’Ivoire, l’économie de plantation de café et de cacao, à travers les fronts pionniers qui ont balayé d’est en ouest la moitié méridionale du pays, a ainsi largement contribué au façonnage du système politique et de l’ensemble de la société civile [3]. Au point que la crise économique, politique et institutionnelle que traverse la Côte d’Ivoire depuis la fin des années 80 se superpose dans une large mesure à la crise du secteur exportateur de café et de cacao, elle-même indissociable de l’épuisement des frontières internes et des difficultés que pose la reproduction des systèmes d’exploitation pionniers (voir, entre autres, les lectures de cette crise que proposent Contamin et Memel-Fotê [4] ; Losch [5] ; Ruf [6].

    Perceptual-motor skills contribute to a variety of basic learning skills associated with normal academic success. This study aimed to determine the relationship between academic performance and perceptual-motor skills in first grade South African learners and whether low SES (socio-economic status) school type plays a role in such a relationship. This cross-sectional study of the baseline measurements of the NW-CHILD longitudinal study included a stratified random sample of first grade learners (n = 812; 418 boys and 394 boys), with a mean age of 6.78 years ± 0.49 living in the North West Province (NW) of South Africa. The Beery-Buktenica Developmental Test of Visual-Motor Integration-4 (VMI) was used to assess visual-motor integration, visual perception and hand control while the Bruininks Oseretsky Test of Motor Proficiency, short form (BOT2-SF) assessed overall motor proficiency. Academic performance in math, reading and writing was assessed with the Mastery of Basic Learning Areas Questionnaire. Linear mixed models analysis was performed with spss to determine possible differences between the different VMI and BOT2-SF standard scores in different math, reading and writing mastery categories ranging from no mastery to outstanding mastery. A multinomial multilevel logistic regression analysis was performed to assess the relationship between a clustered score of academic performance and the different determinants. A strong relationship was established between academic performance and VMI, visual perception, hand control and motor proficiency with a significant relationship between a clustered academic performance score, visual-motor integration and visual perception. A negative association was established between low SES school types on academic performance, with a common perceptual motor foundation shared by all basic learning areas. Visual-motor integration, visual perception, hand control and motor proficiency are closely related to basic academic skills

    Full Text Available “Recueil et parallèle des édifices de tout genre, anciens et modernes”, published in Paris in 1799-1800 by Jean- Nicholas-Louis Durand, at the height of the positivistic climate engendered by the contemporary culture of encyclopedism, plays an important role in architectural historiography. The volume allowed architectural students and architectural enthusiasts alike the first opportunity to study a vast range of architectural design models of all periods and places organised into typological categories, illustrated in highly didactic and homogenous drawings. The immediate success of the “Recueil” was guaranteed by the simultaneous publication (in 1800 of an explanatory text to accompany the illustrative material, written by Jacques Guillaume Legrand in accordance with Durand. More than thirty years later, the Venetian editor Giuseppe Antonelli proposed a re-launch of the “Recueil” intended to meet the contemporaneous historical and critical context of modern Europe, publishing a bilingual Italian-French edition of highly commercially ambitious scope. The Venetian “Raccolta”, which appeared in 1833, united Legrand’s text with Durand’s illustrations, - and importantly included almost double the illustrations- with the addition of antique buildings, and also included modern architectural models, alongside contemporary Italian, French and German architectural design projects. This contribution intends to set Antonelli’s ambitious undertaking into the contemporaneous critical and vivacious academic cultural climate of the Venice of the 1830’s, and also includes a thorough examination of the additional illustrations that were added by the Venetian publisher to the original French canon.

    Full Text Available Children from low-SES families are known to show delays in aspects of language development which underpin reading acquisition such as vocabulary and listening comprehension. Research on the development of morphological skills in this group is scarce, and no studies exist in French. The present study investigated the involvement of morphological knowledge in the very early stages of reading acquisition (decoding, before reading comprehension can be reliably assessed. We assessed listening comprehension, receptive vocabulary, phoneme awareness, morphological awareness as well as decoding, word reading and non-verbal IQ in 703 French first-graders from low-SES families after 3 months of formal schooling (November. Awareness of derivational morphology was assessed using three oral tasks: Relationship Judgment (e.g., do these words belong to the same family or not? heat-heater … ham-hammer; Lexical Sentence Completion [e.g., Someone who runs is a …? (runner]; and Non-lexical Sentence Completion [e.g., Someone who lums is a…? (lummer]. The tasks differ on implicit/explicit demands and also tap different kinds of morphological knowledge. The Judgement task measures the phonological and semantic properties of the morphological relationship and the Sentence Completion tasks measure knowledge of morphological production rules. Data were processed using a graphical modeling approach which offers key information about how skills known to be involved in learning to read are organized in memory. This modeling approach was therefore useful in revealing a potential network which expresses the conditional dependence structure between skills, after which recursive structural equation modeling was applied to test specific hypotheses. Six main conclusions can be drawn from these analyses about low SES reading acquisition: (1 listening comprehension is at the heart of the reading acquisition process; (2 word reading depends directly on phonemic awareness and

    Full Text Available Abstract Background Since 2009, when the revised Pharmaceutical Affairs Act was enacted in Japan, self-medication practices have increased. Because the concept of self-medication was recently introduced in Japan, few studies exist on this topic. Therefore, it is necessary to explore how self-medication is practiced. This study examined Japanese consumers’ self-medication practices and attitudes toward over-the-counter (OTC medicines based on their sex, age, and socioeconomic status (SES. Methods The participants were 403 adults (Mage = 41.1 years, SD = 16.22. A quota sampling method was employed based on age group, and participants completed an online questionnaire. Results Participants in the 20–29 age group reported medical costs as an obstacle in seeing a doctor; in contrast, transportation was a mitigating factor for elderly people. Regarding SES, people at lower SES levels chose to rest instead of seeing a doctor or purchasing over-the-counter (OTC medicines when sick. They also placed more value on national brand OTC medicines than private brands (likely due to advertisements. This finding suggests individuals with a low SES do not select OTC medicines based on their effects or ingredients. Regarding attitudes toward OTC medicines, Japanese participants seemed to be unaware of the potential for abuse and side effects associated with OTC medicines. Finally, in relation to caregivers’ self-medication practices for their children, the majority of participants reported taking their children to the hospital since children tend to receive free medical care. Furthermore, caregivers with a high educational background are more confident in being able to help manage their children’s health. Conclusions Our results suggest that health and medical discrepancies among Japanese consumers pose new social problems. In Japan, universal health care is available, but the cost of receiving medical care is not completely free of charge. Thus

    Full Text Available Problématique: Comme dans plusieurs pays du Sud, le suivi virologique des patients sous traitement antirétroviral (TARV en Guinée est timide voire inexistant dans certaines localités. Le but de cette étude était d’évaluer la faisabilité technique et logistique de l’utilisation des DBS dans les tests de charge virale (CV et de génotypage. Méthode: De septembre à octobre 2010, les DBS ont été préparés à partir de prélèvements sanguins de patients adultes sous TARV. Le délai d’envoi des échantillons au laboratoire de référence était de 30 jours maximum après le prélèvement et se faisait à température ambiante. La CV a été quantifiée et les échantillons de patients en échec virologique (CV ≥ 3 log10 copies/mL ont été génotypés selon le protocole de l’ANRS. L’algorithme de Stanford version 6.0.8 a été utilisé pour l’analyse et l’interprétation des mutations de résistance. Résultats: Parmi les 136 patients inclus, 129 et 7 étaient respectivement sous première et deuxième ligne de traitement avec une médiane de suivi de 35 mois [IQR: 6-108]. L’échec virologique a été noté chez 33 patients. Parmi eux, 84.8% (n = 28/33 ont bénéficié d’ungénotypage. Le taux de résistance global était de 14% (n = 19/136. Le CRF02_AG était le sous type viral le plus prévalent (82%; n = 23. Conclusion: En plus de montrer la faisabilité technique et logistique des tests de CV et de génotypage à partir des DBS, ces résultats montrent l’intérêt de leurs utilisations dans le suivi virologique des patients sous TARV.

    Full Text Available Cet article examine les idées de l’institutrice Anna Lampérière, l’une des rares femmes à avoir contribué à la discussion théorique sur l’idéologie de la solidarité pendant la Troisième République. Vue dans le contexte de son parcours personnel et de son engagement civique, la pensée d’A. Lampérière offre un aperçu inédit d’un modèle solidariste de citoyenneté féminine sans droit de vote. Au sein d’une culture d’associations florissante au début du XXe siècle, elle participe à la création et au fonctionnement d’importantes associations mixtes qui, par l’éducation civique, visent la mise en place de l’idéologie solidariste de Léon Bourgeois. Se proclamant anti-féministe, Anna Lampérière se présente néanmoins comme une défenseuse de la cause des femmes et du progrès social et, comme beaucoup de ses contemporains, elle place la réforme scolaire au cœur de son projet républicain. Après une analyse de la vision sociale d’Anna Lampérière, l’article examine les pratiques civiques et la structure mixte selon les sexes de la Société pour l’éducation sociale, une association pour la promotion du solidarisme, dont elle a été Secrétaire générale. L’idéologie solidariste et sa pratique avaient un attrait pour des femmes républicaines comme Anna Lampérière qui avaient une vocation civique mais qui n’étaient pas attirées par un modèle égalitaire de la citoyenneté.Anna Lampérière, solidarité and female citizenship in the Third Republic This article explores the ideas of educator Anna Lampérière, one of the rare women to contribute significantly to the theoretical discussion about the ideology of solidarity during the Third Republic.

It argues that developing countries must adopt a progressive approach to health policy which rejects the two-tiered system of public and private health care. However, it also points out that ideology is not sufficient to maintain support. A progressive health system must utilize administrative and social and behavioral sciences to achieve effectiveness and efficiency in health care delivery. It cannot ignore these goals any more than a private health care system can.É discutida a política de saúde em países em desenvolvimento. Defende-se a proposta de que esses países devem adotar uma abordagem progressista quanto a sua política de saúde, rejeitando o sistema que se apoia em dois pilares - o da saúde pública e privada.

    Full Text Available O presente estudo tem o objetivo de verificar se investimentos simultâneos em vários mercados internacionais de ações são mais atrativos do que aqueles realizados somente em um único mercado nacional, ou seja, se os primeiros apresentam uma relação risco-retorno superior. Pode-se admitir que se houver uma total integração entre os países analisados, tem-se pouca vantagem na diversificação internacional, mas se os mesmos forem menos integrados, a diversificação traria vantagens em termos de risco e retorno. A base empírica do trabalho está fundamentada na teoria de carteiras de Markowitz, no CAPM e nos índices de medição do desempenho de carteiras de Sharpe, Treynor e Jensen. A análise foi feita para o período de fevereiro de 1993 a janeiro de 2003, com base nas ações mais negociadas nas bolsas dos principais países da América Latina.

    2013-07-01

    Full Text Available Se propone un modelo teórico para explicar la heterogeneidad observada en la adopción de leyes antidumping por pequeños países en vía de desarrollo en un contexto de reducción arancelaria multilateral. El análisis se basa en un juego de tres etapas de determinación de política comercial con competencia imperfecta en productos diferenciados, donde la posible presión para la protección se refleja en la función objetivo del gobierno y donde los aranceles se pueden consolidar como resultado de acuerdos comerciales multilaterales. Este marco implica que la aplicación de este dispositivo de protección administrativa es la mejor respuesta del gobierno cuando los aranceles consolidados multilaterales alcanzan un umbral los suficientemente bajo. La heterogeneidad en la decisión de adopción se explica por el tamaño relativo del mercado nacional, el grado de diferenciación de los productos y los motivos de economía política. Las relativamente grandes economías, los mercados nacionales altamente competitivos y los países con una alta presión interna para la protección promulgan leyes antidumping mucho más rápido.

    Full Text Available Este trabajo pretende analizar las desigualdades existentes entre los inmigrantes provenientes de países pobres y la población autóctona en relación al riesgo de padecer privación material. Asumiendo que, aunque buena parte de este riesgo es inherente a la clase social, hay factores asociados al perfil migratorio que comportan un aumento de dicho riesgo. El trabajo se ha realizado implementando una combinación de análisis factoriales y de clasificación para identificar perfiles de privación material y un análisis logístico multinomial para explorar qué factores sociodemográficos están más asociados a cada tipo de estos. Los resultados confirman que la clase social es un factor muy poderoso para explicar la privación material de los inmigrantes procedentes de países pobres, pero no es el único.

    Full Text Available En el decenio de los 2000 la desigualdad del ingreso en la América Latina se redujo. Este artículo aplica una variante de la metodología de descomposición no paramétrica propuesta por Barros et al (2006, 2007 para evaluar la importancia de las fuentes de ingreso de los hogares, en particular la aportación de las transferencias públicas, en los cambios en la desigualdad de ingresos en los años 2000 en los países del Cono Sur: Argentina, Brasil, Chile y Uruguay. Los resultados sugieren que los ingresos no laborales tuvieron una contribución significativa en los cambios en la desigualdad y que este efecto fue explicado principalmente por la consecuencia igualadora que tuvieron las fuentes públicas en los cuatro países analizados. La dinámica de los cambios en esta fuente de ingreso y su efecto en la desigualdad estuvo fuertemente asociada con la instrumentación o expansión de programas de transferencia no contributivos en el pasado decenio.

    Full Text Available Este estudio descriptivo transversal tuvo como finalidad mostrar la opinión de las familias de cuatro países europeos (España, Austria, Hungría y República Checa a cerca de la prevalencia y el nivel de afectación de trece aspectos relacionados con la convivencia y violencia escolar. Los resultados indican que las familias consideran las peleas, los insultos y las malas palabras en clase como los aspectos más frecuentes en sus centros, y coinciden en señalar el uso o presencia de objetos de agresión y el consumo o presencia de drogas como conflictos menos frecuentes en los centros escolares. En cuanto a la repercusión personal, son los problemas relacionados con el profesorado, las peleas y las dificultades de convivencia intercultural los aspectos que más preocupan. Por países, es Hungría quien presenta tasas más bajas en este tipo de problemas, estando en el lado opuesto Austria y la República Checa y situándose España en un puesto intermedio; del mismo modo, son las familias húngaras quienes se muestran menos afectadas personalmente, destacando únicamente la preocupación de éstas por los problemas de convivencia intercultural.

MÉTODOS: Diseño cualitativo, utilizando análisis de contenido de fuentes primarias y secundarias, revisiones documentales, entrevistas, grupos focales y análisis de casos Las variables seleccionadas incluyeron: criterios de selección, acceso, financiación y regulación en los distintos países. Los MAC se clasificaron en aquellos que no modifican el curso natural de la enfermedad y aquellos que tiene eficacia demostrada, utilizando la dosis diaria definida para comparar los costos entre tratamientos clásicos y los realizados con MAC. RESULTADOS: Los países del Mercosur carecen en su gran mayoría de estrategias formales para enfrentar las demandas de MAC, y gobiernos y aseguradoras terminan por financiarlos por vía judicial. Los análisis de casos muestran que existen MAC sin eficacia comprobada que igualmente generan demanda. Las compras atomizadas, los compromisos internacionales respecto a propiedad intelectual y el bajo poder de negociación incrementan los precios de MAC exponencialmente, poniendo en riesgo la economía de los sistemas sanitarios. CONCLUSIONES: Los MAC deben ser regulados y seleccionados racionalmente permitiendo que solo aquellos que beneficien sustantivamente a la población sean aceptados. Para financiar los MAC así seleccionados se requieren estrategias comunes entre países que incluyan opciones tales como flexibilidades de acuerdos comerciales, creación de fondos nacionales de recursos o compra conjunta entre países para potenciar su poder de negociación.OBJECTIVE: Determine how the Mercosur countries access, regulate, and finance costly drugs and propose joint selection and financing strategies at the subregional level.

    Full Text Available Analisam-se os principais fatôres que contribuiram para a dinâmica populacional dos países desenvolvidos e subdesenvolvidos, a política por êles adotada, bem como a aplicação da demografia em saúde pública. O ritmo de maior crescimento populacional observa-se nos países subdesenvolvidos sendo que, para o ano 2.000, a região denominada de terceiro mundo é a que apresentará o maior contingente populacional pois os países subdesenvolvidos contribuirão com 79% do total da população mundial. A primeira transição demográfica iniciou-se no século 17, na Europa, com o processo de revolução industrial enquanto que, nos países subdesenvolvidos, isto ocorreu a partir do ano de 1940, porém, com uma diferença fundamental, pois a queda de mortalidade verificada não foi acompanhada por um declínio significativo da natalidade nem da modernização de suas economias. Entre os principais fatôres que afetam a mortalidade e a fertilidade analisou-se a influência do desenvolvimento econômico e social e dos avanços no campo da medicina e da saúde pública. Está sob uma política antinatalista oficial 66% da população dos países subdesenvolvidos e os contraceptivos mais utilizados têm sido, em ordem decrescente, o dispositivo intrauterino, esterilização e pílulas. Sòmente a Índia, em 4 anos (1964-68, esterilizou 5.200.000 habitantes com uma idade média de 32,2 anos. Entre as principais aplicações da demografia em saúde pública destacam-se o planejamento de saúde, migrações, epidemiologia e higiene materno-infantil.The main factors that contributed to the population dynamic in developed and underdeveloped countries and the policies of these countries used, even the aplication of demography in Public Health, are analysed. The greater population growth in under developed countries is observed. Thus, by the year 2000, the region called "third world" will present the higger population contingent, for the underdeveloped

    L'idée que la diversité du réel puisse être expliquée par une unité sous-jacente est sans doute aussi ancienne que la pensée elle-même : les grandes mythologies le racontent, les premiers philosophes l'affirment, et la science moderne en a repris le programme en unifiant les conceptions du monde, de la matière et du mouvement. De ce pari métaphysique et quasiment religieux, la physique a aussi fait la vérité de sa démarche : identifier les objets les plus élémentaires possibles, violer les lois les plus fondamentales en cherchant à les raccorder jusqu'à pouvoir les unifier, fournir de l'ensemble la description la plus globale qui soit. Ce que l'on pourrait résumer par l'antique formule des néo-platoniciens : hen-ta-panta, c'est-à-dire l'" Un-toutes-les-choses ". Mais comment appréhender le statut exact de cette quête d'unité ?

    After a theoretical study on the slowing down of a centrifugal pump, the motion equations have been checked by means of experimental tests. In order to have important slowing down times (which is the case of the cooling pumps of a research reactor) it is necessary to add a fly-wheel. To prevent troubles when starting, a block pump-fly-wheel with clutch under controlled torque was developed. It is so possible to start the fly-wheel progressively without increasing too much power of the driving motor. (author) [French] Apres une etude theorique sur le mouvement de ralentissement d'une pompe centrifuge, les equations du mouvement ont ete verifiees par des essais pratiques. Pour obtenir des temps de ralentissement importants (cas des pompes de refrigeration d'un reacteur de recherche) il est necessaire d'y adjoindre un volant d'inertie. Pour eviter les inconvenients au demarrage, on a etudie un ensemble pompe-volant avec embrayage sous couple controle. Cette solution permet de lancer progressivement le volant sans augmentation appreciable de la puissance du moteur d'entrainement. (auteur)

    Full Text Available Le métier de réalisateur de cinéma a été peu étudié en sciences humaines et sociales. Les études cinématographiques et la presse spécialisée s’intéressent beaucoup moins aux parcours des collaborateurs de l’équipe technique qu’aux comédiens et aux projets des auteurs que l’on pourrait croire retranchés dans leur intériorité créatrice. Pour échapper à ce travers biographique, le sociologue peut rendre compte de l’itinéraire d’un réalisateur en examinant ses liens avec ses collaborateurs. On prend ici l’exemple des liens de travail récurrents qui unissent Dominique Cabrera, réalisatrice de cinéma, à ses proches collaborateurs, en montrant de quelle manière des liens de travail peuvent s’approfondir en dépit d’un contexte sectoriel où l’organisation par projet de l’activité cinématographique favorise a priori la fugacité des relations de travail. On postule ainsi que le contexte pertinent pour éclairer les contours de cet itinéraire de carrière est le réseau des relations socioprofessionnelles au sein duquel naissent les projets de films et qui contribuent à ancrer ce parcours dans le paysage professionnel des pratiques cinématographiques.In France, social sciences and humanities have paid little attention to the profession of film director. Film studies and the press are much less interested in the professional careers of technical teams in comparison with the lives of actors and authors of projects who seem to be cut into their inner creativity. To escape the biographical pitfall, sociologists may account for a director’s itinerary by analyzing his/her ties with colleagues. Here, we examine the recurrent work relations between film director Dominique Cabrera and her close colleagues, to underline the strong relationships which paradoxically unite both the director and her staff in a project-based industry that is rather conducive to short-lived work relations. We postulate that the

    Full Text Available El manejo de residuos sólidos es un desafío para las autoridades de las ciudades de los países en desarrollo, principalmente debido al incremento en su generación, la carga impuesta sobre el presupuesto municipal como resultado de los altos costos asociados a su manejo, la falta de comprensión sobre una diversidad de factores que afectan las diferentes etapas del manejo de residuos y los vínculos necesarios para habilitar el funcionamiento de todo el sistema de manejo. Un análisis de la literatura sobre el trabajo realizado y reportado principalmente en publicaciones de 2005 a 2011, relacionadas con el manejo de residuos en los países en desarrollo, demostró que pocos artículos brindan información cuantitativa. El análisis se realizó en dos de las revistas científicas más importantes en gestión de residuos, Waste Management Journal y Waste Management and Research. El objetivo de esta investigación fue determinar las acciones y el comportamiento de los actores sociales que juegan un papel en el proceso de manejo de residuos y analizar factores influyentes en el sistema, en más de 30 áreas urbanas en 22 países en desarrollo de tres continentes. En este estudio se utilizó una combinación de métodos para evaluar a los actores sociales involucrados y los factores que influyen en el manejo de residuos en las ciudades. Se recogieron datos de la literatura científica, bases de datos existentes, observaciones realizadas durante visitas a áreas urbanas, entrevistas estructuradas con profesionales de relevancia, ejercicios suministrados a los participantes en talleres y un cuestionario aplicado a los actores involucrados. Se utilizaron métodos estadísticos descriptivos e inferenciales para sacar conclusiones. El resultado de la investigación es una lista completa de los actores sociales involucrados que son pertinentes en los sistemas de manejo de residuos y un juego de factores que revelan las causas más importantes del

    Full Text Available O objetivo desta pesquisa foi calcular o Índice de Ecoeficiência (IE para 51 países por meio do método Análise Envoltória de Dados (DEA. Verificou-se que o valor da ecoeficiência média diminuiu entre os anos de 1991 e 2012. Houve predominância dos países desenvolvidos e do continente europeu nos maiores índices de ecoeficiência. Os piores resultados foram alcançados por Índia e China. De modo geral, em todos os anos, o IE foi muito baixo na maioria dos países, sendo que metade destes são países em desenvolvimento e localizados, predominantemente, no continente asiático. A principal implicação dos resultados obtidos é de que são necessárias regulamentações mais rigorosas acerca do tema ambiental, principalmente para os países que apresentaram baixos valores de ecoeficiência. A presente análise sobre o Índice de Ecoeficiência busca ampliar o conhecimento sobre o assunto para propor melhores alternativas para alcançar a sustentabilidade tão necessária para as futuras gerações.

Son exercice du pouvoir s’assimile à un « populisme moderne » qui s’est constitué lentement dans le contexte d’une transition démocratique incertaine. Populiste moderne, il utilise tous les moyens pour rester au pouvoir : corruption, milices de jeunes fanatisés, diabolisation des Etats occidentaux, exhortation du peuple… Il a aussi fait appel aux méthodes habituelles du leader populiste : encadrement de la société par la terreur, les médias, le parti, la fraude électorale, la corruption…. Son échec provient des limites de ses soutiens (milices armées incontrôlables, poids et rôle incertains des mafias de la drogue, division interne à son parti, faiblesse de la police, absence d’armée, isolement international. Dans ce contexte, malgré la terreur imposée aux intellectuels et à l’opposition, il n’a pas su empêcher la montée en puissance des mécontentements. Le peuple, manipulé, n’a plus cru en son Président dès les années 2002-2003. Porté par les masses des bidonvilles au pouvoir, Aristide n’a pas répondu à leur attente. Il s’est mis dans la peau d’un populiste sans imagination. Il a échoué dans tous les domaines, sombrant dans une démagogie et un discours sans prise sur l’opinion. Le régime d’Aristide ne fut qu’un populisme de misère, indigne, pour un peuple digne toujours en quête de démocratie.Jean-Bertrand Aristide había sido elegido presidente en 1990 merced a un gran movimiento popular a su favor, cuando declaraba querer llevar a su país « de la miseria indigna a la pobreza digna ».

    Full Text Available The heritage making process is one of the major elements of territorial mediation between politicians and citizens, equally as between the territory and the outside. It carries pictures that have to lean on the identity of the territory. This identity often requires a return to the past or an attention on peculiar elements. The study of landscape images on the Country of Albret (lithographs, postcards, photographs … allows to analyse, over a long period (XIX-XXIth centuries, the construction of meaning that a society gives to its territory. Pictures show identity, personality, values and ambience related to patrimonial places and territory. Techniques, landscapes highlighted and the manner of showing them change over time.

    La patrimonialización es un elemento importante de mediación territorial entre los políticos y sus administrados, y también entre el territorio y el exterior. Transmite imágenes que se apoyan en la identidad del territorio. Esta identidad supone a menudo un retorno al pasado o a cualquier elemento singular. El estudio de las imágenes paisajísticas que se han divulgado sobre el País de Albret a través de diferentes medios (litografías, tarjetas postales, fotografías, etc. permite analizar a lo largo del tiempo (siglos XIX y XX la construcción del sentido que una sociedad da a su territorio: las imágenes transmiten identidad, personalidad, valores y ambiente ligados a los lugares patrimoniales y al territorio. Los soportes iconográficos, los paisajes y los lugares destacados, así como la manera de mostrarlos, evolucionan con el paso del tiempo.

    The aim of this study is examine trends in breast and colorectal cancer screening in the U.S. by race, healthcare coverage, and socio-economic status (SES) before the Great Recession (2003-2005), during the recession (2007-2009), and post-recession/Affordable Care Act (ACA) period (2010 - 2012). Data on a representative sample of U.S. adults was obtained from the Behavioral Risk Factor Surveillance System (BRFSS). Breast and colorectal cancer screening were defined in line with U.S. Preventative Services Task Force guidelines, and survey weighted statistical methods were utilized to analyze trends in cancer screening among 1,858,572 BRFSS participants. Overall, 83% of women received mammograms in the past 2 years, while 95% of adults received colorectal cancer screening in the past 10 years. Compared with the pre-recession period, the odds of colorectal screening within 5 years were slightly higher during the recession (OR: 1.05, 95% CI: 1.03-1.08) but significantly lower in the post-recession/ACA period (OR: 0.73, 95% CI: 0.72-0.75). Odds of mammography screening were lower during (OR: 0.94,95% CI: 0.91-0.96) and post-recession/ACA period (OR: 0.80, 95% CI: 0.78-0.82). Breast cancer screening rates declined in the recession and post-recession, while colorectal cancer screening rates increased during the recession and decreased post-recession. Low SES adults and those without healthcare coverage were the least likely to receive screening.

A partir de un análisis bibliográfico se discuten las perspectivas teóricas sobre migración calificada y se detectan las tendencias históricas de este proceso en América Latina. Para el análisis empírico se utilizó una novedosa base de datos sobre tasas de emigración según nivel educativo. La evidencia empírica demostró que se registró un incremento del stock de migrantes con estudios superiores entre 1990 y 2000, en términos absolutos y relativos respecto a los migrantes con niveles educativos bajo y medio. Las mujeres experimentaron una tasa de emigración calificada mayor que los hombres. Los pequeños Estados, con escaso nivel de desarrollo, tienen las tasas de migración calificada más elevadas. Paradójicamente, los países con diásporas más reducidas muestran los niveles de selectividad más altos. Aproximadamente 40 por ciento de los profesionales no encuentran empleo en profesiones de ámbito científico e ingenierías encontrándose subocupados y su talento desperdiciado.

    Full Text Available Los países andinos transitan hacia la televisión digital al mismo tiempo en que se consolidan los medios sociales que otorgan a la audiencia la capacidad de interactuar en tiempo real, ello deriva en interrogantes como ¿existe integración de los medios sociales en la televisión?, ¿la audiencia participa en la definición de la televisión digital? y ¿estamos frente a la televisión social? La investigación pretende responder a las preguntas señaladas mediante el estudio de los programas de noticias y magazines de las estaciones de televisión líderes del área andina, en razón de que sus contenidos se emiten en tiempo real cuando se generaría el mayor interés de la audiencia. La metodología empleada es cuantitativa y cualitativa a partir del análisis de cuentas en Facebook y Twitter de las estaciones. Las hipótesis son que la televisión social gana aceptación en los países del área andina y que los canales de televisión no explotan los medios sociales. Se concluye que las estaciones privadas muestran más actividad que las públicas, que existe diferencia entre los informativos y el entretenimiento en seguidores y actividad en la red y que estamos en el inicio de la televisión social pero demanda más esfuerzos para integrar pantallas y medios sociales.

  11. Farming or seasonal migration? - Potential futures of reindeer husbandry in Fennoscandia studied with Social-Ecological System (SES) approach, co-production of knowledge, and scenarios

    The area allocated for reindeer husbandry in Finland, Sweden and Norway covers approximately 40 % of each country. As the livelihood requires large, relatively unfragmented territories while being marginal in terms of direct income, land-use conflicts between various livelihoods and activities, such as forestry, agriculture, mining, energy production, tourism, and nature protection are common phenomena in the region. Simultaneously, rapid societal change, urban exodus and fading traditions as well as climate warming and subsequent ecosystem change may put the livelihood at stake. We have probed potential futures of reindeer husbandry in Northern Fennoscandia using the Social-Ecological System (SES) approach, knowledge co-production in stakeholder-scientist workshops in all three countries, and scenario building based on quantitative data and narratives. Regarding the future of the livelihood, we have identified some crucial components in the SES that are influential in determining the direction of development. We produced four potential pathways of future development and demonstrate that important factors controlling the direction of development include governance and actor relations. Governance is often considered distant and opaque by local stakeholders, fostering conflicts in land allocation, while unclear regulations at local level reinforce emerging conflict situations leading to distrust and restrained communication between the actors. Regionally, these conflicts may lead to decreased resilience and threaten the future of the livelihood altogether. Therefore, research should focus on supporting the reform process of institutional arrangements and governance mechanisms, and fostering co-design and co-production processes that ease distrust and improve resilience of the livelihood in multifunctional landscapes.

    Full Text Available OBJECTIVE: To assess the prevalence of preterm birth among low birthweight babies in low and middle-income countries. METHODS: Major databases (PubMed, LILACS, Google Scholar were searched for studies on the prevalence of term and preterm LBW babies with field work carried out after 1990 in low- and middle-income countries. Regression methods were used to model this proportion according to LBW prevalence levels. RESULTS: According to 47 studies from 27 low- and middle-income countries, approximately half of all LBW babies are preterm rather than one in three as assumed in studies previous to the 1990s. CONCLUSIONS: The estimate of a substantially higher number of LBW preterm babies has important policy implications in view of special health care needs of these infants. As for earlier projections, our findings are limited by the relative lack of population-based studies.OBJETIVO: Estimar la prevalencia de recién nacidos pre-término entre los recién nacidos de bajo peso al nacer de países de renta media o baja. MÉTODOS: En consulta a bases de datos (PubMed, LILACS, Google Scholar fueron procurados estudios sobre la prevalencia de recién nacidos a término y pre-término entre aquellos de bajo peso al nacer conducidos posteriores a 1990 en países emergentes. Modelos de regresión fueron usados para evaluar la proporción de acuerdo con las prevalencias de bajo peso. RESULTADOS: Con base en 47 estudios de 27 países emergentes, aproximadamente la mitad de todos los recién nacidos con bajo peso serían prematuros, y no uno de cada tres, como se estimó en estudios anteriores a la década de 1990. CONCLUSIONES: La estimación de números sustancialmente más altos de prematuros con bajo peso tiene importantes consecuencias en la planificación de salud, ya que tales recién nacidos demandan cuidados especiales.

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

    Full Text Available Objective. To analyze the effects of socioeconomic, regional, and ethnic conditions on chronic malnutrition in four Andean countries of South America: Bolivia, Colombia, Ecuador, and Peru. Methods. The study was based on Demographic and Health Surveys (DHS for Colombia (1995, Peru (1996, and Bolivia (1997, and on a Living Standard Measurement Survey for Ecuador (1998. We developed an index of household socioeconomic status using categorical principal components analysis. We broke down the prevalence of stunting by socioeconomic status (SES, ethnicity, place of residence (large cities, small cities, towns, and countryside, and region (highland region versus other areas of the country. We applied smoothed regression curves and linear functions to analyze SES effects on stunting, with specific models for Bolivia, Ecuador, and Peru. Results. Bolivia, Ecuador, and Peru have similar characteristics, with high stunting prevalences overall; higher stunting prevalences in their highland areas, particularly among indigenous populations; and strong socioeconomic disparities. Colombia, in contrast, has a lower stunting prevalence and smaller regional disparities. The socioeconomic gradient of stunting is strong in all four countries, with prevalence rates in the poorest deciles at least three times as high as those in the top decile. Discussion. The sharp contrast between the conditions found in Bolivia, Ecuador, and Peru and those in Colombia may be the result of specific ethnic factors affecting indigenous groups; a particular diet profile in the highland areas, with low protein and micronutrient intake; and differences in the long-term economic and social development paths that the countries have taken. Along with the strong socioeconomic gradient in all the countries, the weight of ethnic and regional factors suggests the need to reduce inequality as well as to comprehensively improve education and housing, better target health and nutrition programs

    The authors consider the various methods of machining uranium mono-carbide and compare them critically in the case of their application to uranium carbide obtained by fusion under an electronic bombardment and continuous casting. This study leads them to propose two mechanical machining methods: cylindrical rectification and center-less rectification, preceded by a preliminary roughing out of a cylinder, the latter appearing more suitable. A study of the machining yields as a function of the diameter of the rough bars and of the diameter of the finished rods has shown that an optimum value of the rough bar diameter exists for each value of the finished rod diameter. It is found that the yield increases as the diameter itself increases, this yield rising from 45 per cent to around 70 per cent as the diameter of the rough bars increases from 25-26 mm to 37-38 mm. (authors) [French] Les auteurs envisagent les differentes methodes d'usinage du monocarbure d'uranium et se livrent a une etude critique de celles-ci, dans le cas de leur application a l'usinage de barreaux de carbure d'uranium obtenus par fusion sous bombardement electronique et coulee continue. Cette etude les conduit a proposer deux methodes d'usinage mecanique: la rectification cylindrique et la rectification 'centerless', precedee d'un ebauchage par carottage, la seconde paraissant la plus appropriee. L'etude des rendements d'usinage en fonction du diametre des barreaux bruts et du diametre des barreaux finis, a mis en evidence une valeur optimale du diametre des barreaux bruts pour chaque valeur du diametre des barreaux usines. Elle a montre que le rendement croit lorsque le diametre croit lui-meme, ce rendement passant d'environ 45 pour cent a environ 70 pour cent, lorsque le diametre des barreaux bruts passe de 25-26 mm a 37-38 mm.

    With a view to their use in the exchangers of nuclear reactors of the graphite-gas or heavy water-gas types, the behaviour of chromium-aluminium steels containing up to 7 per cent chromium and 1.5 per cent aluminium has been studied in the presence of high-pressure carbon dioxide at temperatures of between 400 and 700 deg. C. The two most interesting grades of steel (2 per cent Cr - 0.35 per cent Al - 0.35 per cent Mo and 7 per cent Cr - 1.5 per cent Al - 0.6 per cent Si) are still compatible with carbon dioxide up to 550 and 600 deg. C respectively. A hot dip aluminised coating considerably increases resistance to oxidation of the first grade and should make possible its use up to temperatures of at least 600 deg. C. (authors) [French] Dans l'optique de leur emploi dans les echangeurs de reacteurs nucleaires des filieres graphite-gaz ou eau lourde-gaz, le comportement en presence de gaz carbonique sous pression d'aciers au chrome-aluminium, contenant jusqu'a 7 pour cent de chrome et 1,5 pour cent d'aluminium a ete etudie entre 400 et 700 deg. C. Les deux nuances les plus interessantes (2 pour cent Cr - 0,35 pour cent Al - 0,35 pour cent Mo et 7 pour cent Cr - 1,5 pour cent Al - 0,6 pour cent Si) restent compatibles avec le gaz carbonique jusqu'a 550 et 600 deg. C respectivement. Un revetement d'aluminium, effectue par immersion dans un bain fondu, ameliore notablement la resistance a l'oxydation de la premiere et doit permettre son empioi jusqu'a 600 deg.

    Full Text Available OBJECTIVES: This article reports the prevalence of two types of interpersonal violence (IPV (sexual and physical and one type of aggression (psychological in three low-to-middle-income Caribbean countries. It examines IPV among adolescents and young adults as both victims and perpetrators. METHODS: This population-based study compares the experiences of 15-30 year olds in countries at different levels of socioeconomic development. The Revised Conflict Tactics Scales (CTS2 and other behavioral instruments were used to assess the level and characteristics of IPV. RESULTS: Out of 3 401 respondents, 70.9% reported victimization by some form of violence, which was most commonly perpetrated by a relationship partner (62.8%. Sexual violence victimization was reported more commonly by women, and was highest in Jamaica. Significant between-country differences in overall levels of reported physical violence, and psychological aggression, were evident when stratifying by perpetrator type. CONCLUSIONS: The very high levels of reported IPV indicate very high levels of tolerance among victims, and suggest a culture of violence and of adversarial intimate relationships may be well entrenched. The findings support the view that co-occurrence of general interpersonal violence and partner violence may be limited, and that one may not necessarily be a predictor of the other. They also reveal that, among partners, not only are there no gender differentials in victimization by physical violence, but more women than men are self-reporting as perpetrators of this type of IPV.OBJETIVOS: Se informa la prevalencia de dos formas de violencia interpersonal (VIP -la sexual y la física- y de un tipo de agresión -la psicológica- en tres países del Caribe de bajo a mediano ingresos. Se analiza la VIP entre adolescentes y adultos jóvenes, ya sea como víctimas o agresores. MÉTODOS: En este estudio basado en la población se comparan las experiencias de personas de 15 a 30

Cooperative self-help techniques often provide alternative means for lower income people to imporve their own shelter and community services with a minimun of outside assistance. These techniques may often require the introduction of less advanced, but appropriate building technology is important. It is, however, only one part of a comprehensive system needed to produce better housing. In many countries, technology is the least important constraint; more serious concerns are building technology is important. It is, however, only one part of a comprehensive system needed to produce better housing. In many countries, technology is the least important constraint; more serious concerns are managerial and financial obstacles. The Building Materials Production Centers concept is part of a larger shelter development strategy; a "Cooperative Development System 1 aimed at promoting low-cost housing in developing countries. The self-help construction that takes place in squatter settlements and rural areas is often poorly served by the formal construction industry material suppliers and must rely on informal material production systems for building materials. Building Materials Production Centers can be established to meet the needs of these settlement areas in a more efficient way at a reasonable cost and at locations where people are improving their own housing and communities.

This paper shows the results obtaind in the study of the Netherlands, a country so many times regarded as a referencen in democracy (and so in culture of peace in Europe. Culture of peace is a project defended and promoted by UNESCO, vertebrated in a whole theoretical and conceptual universe, that not only means the absense of war, but focuses all kind of human and social relationships. In order to this purpose, we have analyzed carefully the whole 26 Government’s campaigns. Los últimos años los he dedicado a estudiar el fomento de la cultura de paz a través de la publicidad institucional que la Administración General del Estado (España contrataba para televisión. Año tras año, veía que los resultados eran los mismos, así que decidí investigar qué sucedía a propósito del mismo fenómeno, en otros países. Este texto presenta los resultados obtenidos sobre el caso de los Países Bajos, un estado que en muchos casos ha sido referente de los valores democráticos (y por ende de la cultura de paz en Europa. En este artículo se describe y analiza la publicidad institucional del estado neerlandés en el fomento de la cultura de paz. La cultura de paz es un proyecto defendido promovido por la UNESCO, vertebrado en todo un universo teórico y conceptual, que no se refiere únicamente a la paz como ausencia de guerra, sino que incide en todas las formas de relaciones humanas y sociales.

Inicialmente, são apresentadas as principais causas do aquecimento terrestre e como a utilização de combustíveis fósseis amplia o efeito estufa. Em seguida, são estimadas as emissões de CO2 para três cenários alternativos utilizando-se da Identidade de Kaya. Nos três cenários foram considerados que o aumento populacional e o crescimento da economia seguiriam as taxas médias do período 2000-05. Tentou-se avaliar os efeitos da redução dos índices de intensidade energética e de CO2, mantida a mesma taxa de crescimento econômico e populacional. Neste sentido, nem mesmo no cenário no qual é previsto um maior uso de energias renováveis e de tecnologias voltadas à proteção do meio ambiente, foi possível reduzir os níveis de emissões de CO2 em todos os países.Abstract The main aim of this paper is to evaluate the emissions of carbon dioxide in 2012 as consequence of economic activities in developing countries (South Africa, Argentina, Brazil, China, India and Mexico.

Then we estimate the CO2 emissions in three alternatives scenarios, using Kaya identity. In the three scenarios was 25consider the economic growth and increase in population equal to period 2000-05. In each scenario, we try to evaluated the effects of reduce the index of energy intensity and CO2. As result, even in the scenario where we simulate major changes in renewable energy and the use of appropriate technologies, it was not feasible to reduce the level of CO2 emission in all the countries.

Con el objetivo de conocer dónde se ubica la responsabilidad para la realización de diferentes tipos de actividades preventivas, se realizó una encuesta en ocho áreas geográficas de seis países de Europa y Norteamérica. Métodos: Encuesta entre expertos basada en una matriz que relaciona servicios sanitarios preventivos con la población a la que se dirigen. Se establecieron ocho situaciones clínicas (vacunaciones infantiles y antigripal adultos; y detección precoz: de cáncer mediante mamografía, de tuberculosis, de Hipertensión Arterial, de fenilcetonuria, del virus de la inmunodeficiencia humana, y de osteoporosis, con el fin de conocer en relación a las mismas la población diana, nivel de establecimiento de las políticas, nivel de contacto con los individuos, seguimiento de los individuos con diagnósticos positivos y registro de sus datos clínicos. Resultados: Este estudio piloto mostró muy escasa coincidencia de los resultados tanto entre las ocho áreas encuestadas como en cada una de ellas. No se encontró un patrón regular para las actividades de prevención exploradas entre los diferentes países, ni en función de la tipología de sus sistemas sanitarios, ni por la orientación hacia la atención primaria de los diferentes sistemas. Conclusiones: Existe un escaso consenso en las áreas estudiadas en relación con la mejor forma de realizar las intervenciones de salud pública que conllevan prestación de atención sanitaria personal.

En Georgia y Letonia el 100% de los casos de SIDA se da entre personas con edades comprendidas entre los 15 y los 49 años. En España el 90% de los casos también se da en este rango de edad. Rumanía es el país con mayor porcentaje de casos de niños con SIDA y posee además un alto porcentaje de mujeres con la enfermedad. En Bulgaria se da un predominio de la transmisión heterosexual (93% y en Hungría predomina la homosexual (74%. Las conclusiones más relevantes son que las vías más importantes de transmisión del VIH/SIDA en Europa son el consumo de drogas por vía parenteral y las relaciones homosexuales. Para la lucha contra el SIDA se deben realizar medidas de prevención dirigidas sobre todo a los jóvenes, puesto que la mayoría de las infecciones tiene lugar durante o poco después de la adolescencia.

    Full Text Available Esta pesquisa objetivou identificar a existência de relações entre as variáveis: nível de independência e nível de atuação de uma Instituição Superior de Auditoria e o nível de transparência de uma nação, utilizando a técnica de regressão logística binária. A amostra estudada foi composta por dados de 85 países, obtidos da base de dados do Open Budget Initiative 2008. Apenas a variável nível de atuação foi considerada significativa, não sendo possível identificar a existência de relação entre o nível de independência e o nível de transparência fiscal. O modelo resultante da regressão logística binária apresentou probabilidade de correta classificação de 92,9%. Considerando-se as duas categorias do modelo, baixo ou regular e bom nível de transparência a percentagem de correta classificação foi de 94,7% e 50,0%, respectivamente. Estas constatações validaram parcialmente a hipótese de que bom nível de independência e bom nível de atuação de uma instituição Superior de Auditoria estão associados a um bom nível de transparência fiscal, propiciando a afirmação de que nos países em que as Instituições Superiores de Auditoria são atuantes, os gestores se pré-dispõem a utilizar práticas relacionadas com a transparência fiscal.

Las simulaciones muestran que en países con alta mortalidad, v.g.

Este ejercicio teórico muestra en todas las simulaciones que el tamaño de la población de los países de América Latina, que iniciaron su transición demográfica décadas atrás, no experimentará un crecimiento considerable. La población de Brasil y de Argentina, aún al alcanzar su límite teórico, no se duplicará. A pesar de que el límite teórico de las poblaciones analizadas se alcanzará en 400 a 500 años, éstos alcanzarán un estado “cuasi-estable” entre los años 2050 y 2100.

    This study investigated how trilinguals fare on the cross-linguistic lexical tasks (CLT)-Afrikaans, -isiXhosa and -South African English (SAE) (cf. Haman et al., 2015) compared to monolingual controls, and whether the CLT-Afrikaans renders comparable results across socioeconomic status (SES) backgrounds. The LITMUS-CLTs were administered to 41 low SES 4-year-olds (11 trilinguals; 10 monolingual speakers of Afrikaans, isiXhosa and SAE) and the LITMUS-CLT-Afrikaans to 11 mid-SES 4-year-old monolinguals. Results (a) indicate that trilinguals' proficiency in their exposure-dominant language did not differ significantly from monolinguals' proficiency, but their proficiency in their additional two languages was significantly lower than monolinguals' proficiency; (b) reflect the extent, but not current amount, of exposure trilinguals had had over time to each of their languages; and (c) show that low and mid-SES monolinguals differed significantly on noun-related, but not verb-related, CLT measures. Possible reasons for and the clinical implications of these results are discussed.

Cet article analyse les liens entre exigences du travail et emploi des seniors, dans les pays d’Europe. La réflexion proposée fait appel à l’ergonomie et à la démographie. Des études locales et des approches statistiques attirent en effet l’attention sur des difficultés, particulièrement sensibles chez les âgés, liées à quatre catégories d’exigences : postures pénibles, horaires décalés, pression temporelle élevée, ou changements rapides de techniques ou d’organisation. Pour chacune de ces quatre caractéristiques, l’article explique en quoi elles sont problématiques pour les âgés, puis interroge leur lien avec l’emploi des seniors dans 25 pays, à l’aide des données de l’enquête européenne sur les conditions de travail. Nos résultats suggèrent que les pays « performants » en termes d’emploi des seniors ont su, mieux que les autres, maîtriser ou aménager ces caractéristiques du travail, en particulier en limitant les sollicitations physiques et en favorisant les apprentissages tout au long de la vie professionnelle.Employment rates of ageing workforce have become a major concern, in particular for international organisms. In this article we analyze the links between work constraints and employment of elderly, by comparing various European countries. Ergonomic and demographic methodologies are being called on. Local studies and statistical approaches actually emphasize difficulties, especially perceived by elderly workers, in relation with four main types of constraints : painful positions, shift work, high time pressure, and fast paced changes in techniques or organisation. For each of these characteristics, we first recap why it is tricky for elderly, then we study its relations with seniors’ employment rate in 25 countries, using the ESWC data (European Survey on Working
