    Introduction Analyse du profil bactériologique des pieds diabétiques pris en charge à l'hôpital militaire de Rabat et son influence sur l'antibiothérapie de première intention. Méthodes Etude prospective non randomisée étalée sur 18 mois, ayant concerné 105 patients. Après recueil des données et en attente des résultats bactériologiques nos patients ont été divisés en deux groupes: un groupe a été mis sous Amoxicilline + Acide clavulanique + Gentamycine (59 patients) et un groupe sous Ertapénème±Gentamycine (46 patients). Résultats L’étude a regroupé 85 hommes et 20 femmes (sexe ratio = 4.26). L’âge moyen est de 64.4 ans. La gangrène a été observée chez 79% des malades; elle était humide-donc surinfectée en principe- dans 43% des cas. Par ailleurs, 67% des malades ont un chiffre de globules blancs 12000 définissant une infection sévère. L'ostéolyse a été mise en évidence chez 27% de nos patients. Parmi les différentes techniques de prélèvements: 81% ont été profonds dont 21% de biopsie osseuse per opératoire et 14% de prélèvements combinés. 42% de ces prélèvements sont poly microbiens et 21% sont stériles. Les résultats bactériologiques viennent confirmer la prédominance des bactéries aérobies à Gram positif. Le taux de remplacement de l'Ertapénème est de 22% contre un taux de 50% pour l'Amoxiclav. Conclusion L'antibiothérapie ne doit être instaurée qu'en cas d'infection du pied diabétique diagnostiquée sur les critères cliniques établis par les consensus internationaux récents. Le respect des mesures de lutte contre la diffusion de la résistance bactérienne s'avère primordiale. PMID:27386024

    La presente these s'inscrit dans le cadre d'un projet strategique sur les arenas finance par le CRSNG (Conseil de Recherche en Sciences Naturelles et en Genie du Canada) qui a pour but principal le developpement d'un outil numerique capable d'estimer et d'optimiser la consommation d'energie dans les arenas et curlings. Notre travail s'inscrit comme une suite a un travail deja realise par DAOUD et coll. (2006, 2007) qui a developpe un modele 3D (AIM) en regime transitoire de l'arena Camilien Houde a Montreal et qui calcule les flux de chaleur a travers l'enveloppe du batiment ainsi que les distributions de temperatures et d'humidite durant une annee meteorologique typique. En particulier, il calcule les flux de chaleur a travers la couche de glace dus a la convection, la radiation et la condensation. Dans un premier temps nous avons developpe un modele de la structure sous la glace (BIM) qui tient compte de sa geometrie 3D, des differentes couches, de l'effet transitoire, des gains de chaleur du sol en dessous et autour de l'arena etudie ainsi que de la temperature d'entree de la saumure dans la dalle de beton. Par la suite le BIM a ete couple le AIM. Dans la deuxieme etape, nous avons developpe un modele du systeme de refrigeration (REFSYS) en regime quasi-permanent pour l'arena etudie sur la base d'une combinaison de relations thermodynamiques, de correlations de transfert de chaleur et de relations elaborees a partir de donnees disponibles dans le catalogue du manufacturier. Enfin le couplage final entre l'AIM +BIM et le REFSYS a ete effectue sous l'interface du logiciel TRNSYS. Plusieurs etudes parametriques on ete entreprises pour evaluer les effets du climat, de la temperature de la saumure, de l'epaisseur de la glace, etc. sur la consommation energetique de l'arena. Aussi, quelques strategies pour diminuer cette consommation ont ete etudiees. Le considerable potentiel de recuperation de chaleur au niveau des condenseurs qui peut reduire l'energie requise par

    Optical fibres are widely used as physical and mechanical sensors in various matrices. Those commercial available fibres are mostly coated with different polymers (e.g. polyimide). The problem of using such coatings is the undefined adhesion and the stress transmission from the matrix material into the fibre as well as the alkaline attack from the cementitious environments onto the glass surface. Therefore the known silanisation process with alkylsilanes for surface modification was studied. To achieve a silane film onto the fibre surface as close as possible a fibre pre-treatment in oxygen plasma was applied. The wetting behaviour of the oxygen plasma treated fibres as well as the silanized fibres were studied using the Wilhelmy-method. The influence of the silane concentration and the time of the pre-treatment on the wetting properties was investigated. By scanning electron microscopy, changes of the surface morphology were detected. Additionally, the mechanical properties of the oxygen plasma treated fibres, and silanized fibres exposed to a highly alkaline pore solution were measured. For selected fibre samples (decoated and untreated as well as silanized fibres) the adhesion to a concrete matrix was studied using the indention test. Les fibres optiques sont de plus en plus utilisées comme capteurs des propriétés physiques et mécaniques de nombreuses matrices. Ces fibres commerciales sont généralement enrobées avec différents polymères (par exemple polyimide). Les problèmes dus à l'enrobage des fibres optiques sont une adhésion et une transmission de charge de la matrice du béton à la fibre non définies. Un autre problème majeur est l'alcalinité du béton et son influence sur la surface de la fibre. Nous avons utilisé le procédé de silanisation. Pour obtenir un film de silane le plus homogène possible sur la surface, les fibres sont pré-traitées par le plasma d?oxygène. Le mouillage de fibres traitées par le plasma d?oxygène, ainsi que

  4. Einfluss des Internets auf das Informations-, Einkaufs- und Verkehrsverhalten

    Mit Daten aus eigenen Erhebungen können das einkaufsbezogene Informations- und Einkaufsverhalten im Zusammenhang mit den verkehrlichen Aspekten (Distanzen, Verkehrsmittel, Wegekopplungen) dargestellt werden. Die Differenzierung in die drei Produktkategorien des täglichen, mittelfristigen und des langfristigen Bedarfs berücksichtigt in erster Linie die Wertigkeit eines Gutes, die seine Erwerbshäufigkeit unmittelbar bestimmt. Der Einsatz moderner IKT wie das Internet eröffnet dem Endverbraucher neue Möglichkeiten bei Information und Einkauf. Die verkehrliche Relevanz von Online-Shopping wird deutlich, wenn man berücksichtigt, dass im Mittel rund 17% aller Online-Einkäufe, die die Probanden durchgeführt haben, Einkäufe in Ladengeschäften ersetzen. Dies gilt in verstärktem Maße für Online-Informationen: etwa die Hälfte hätte alternativ im stationären Einzelhandel stattgefunden. Da der Erwerb von Gütern des täglichen Bedarfs häufig nahräumlich und in relevantem Anteil nicht-motorisiert erfolgen kann, sind in diesem Segment - im Gegensatz zum mittel- und langfristigen Bedarf - nur geringe Substitutionseffekte zu beobachten.

    1995-01-01

    This article assesses the strength of son preference in Vietnam, as reflected in fertility behavior. It formulates and estimates a proportional hazards model applied to birth intervals, and a contraceptive prevalence model, using household survey data from 2,636 ever-married women aged 15-49 with at least one living child who were interviewed for the Vietnam Living Standards Survey 1992-1993. Son preference is found to be strong by world standards, but nevertheless, it has a minor effect on fertility; in its absence, the total fertility rate would fall by roughly 10 percent from the current level of about 3.2 children per woman of reproductive age.

    The Nam Con Son basin is the largest oil and gas bearing basin in Vietnam, and has a number of producing fields. The history of studies in the basin can be divided into four periods: Pre-1975, 1976-1980, 1981-1989, and 1990-present. A number of oil companies have carried out geological and geophysical studies and conducted drilling activities in the basin. These include ONGC, Enterprise Oil, BP, Shell, Petro-Canada, IPL, Lasmo, etc. Pre-Tertiary formations comprise quartz diorites, granodiorites, and metamorphic rocks of Mesozoic age. Cenozoic rocks include those of the Cau Formation (Oligocene and older), Dua Formation (lower Miocene), Thong-Mang Cau Formation (middle Miocene), Nam Con Son Formation (upper Miocene) and Bien Dong Formation (Pliocene-Quaternary). The basement is composed of pre-Cenozoic formations. Three fault systems are evident in the basin: north-south fault system, northeast-southwest fault system, and east-west fault system. Four tectonic zones can also be distinguished: western differentiated zone, northern differentiated zone, Dua-Natuna high zone, and eastern trough zone.

    Examining the factors that influence adolescents' sexual behaviors is crucial for understanding why they often engage in risky sexual behaviors. Using social cognitive theory, we examined predictors of father-son communication about sexuality. Fathers (N=155) of adolescent sons completed a survey measuring 12 variables, including self-efficacy and outcome expectations. We found that (a) son's pubertal development, father's sex-based values, father's education; father's communication with his father, outcome expectations, and general communication accounted for 36% of the variance in information sharing communication and (b) son's pubertal development, outcome expectations, general communication, and father-son contact accounted for 20% of the variance in values sharing communication. Study findings can aid professionals in designing guidelines for programs to promote father-son general communication and sex-based communication. PMID:16123842

  11. ...And Kronos Ate His Sons

    NASA Astrophysics Data System (ADS)

    Vitiello, Giuseppe

    In closed systems, energy is conserved. The origin of the time axis is completely arbitrary due to the invariance under continuous time-translations. The flowing of time swallows those fictitious origins one might assign on its axis, as Kronos ate his sons. Dissipation breaks such a scenario. It implies a non-forgettable origin of time. Open systems need their complement (their "double") in order to become, together, a closed system. Time emerges as an observable measured by the evolution of the open system complement, which acts as a clock. The conservation of the energy-momentum tensor in electrodynamics is considered and its relation with dissipative systems and self-similar fractal structures is discussed. The isomorphism with coherent states in quantum field theory (QFT) is established and the generator of transitions among unitarily inequivalent representations of the canonical commutation relations (CCR) is shown to provide sequences in time of phases, which defines the arrow of time. Merging properties of electrodynamics, fractal self-similarity, dissipation and coherent states point to an integrated vision of Nature.

  14. The experience of sons caring for a parent with dementia.

    PubMed

    McDonnell, Eilis; Ryan, Assumpta A

    2014-11-01

    This study explored the experiences of sons caring for a parent with dementia. Individual, semi-structured interviews were conducted with a purposeful sample of sons (n = 13) in a rural part of Ireland. Interviews were audiotaped, transcribed verbatim and analysed for common themes. The key themes that emerged were 'the parental bond', 'a binding role', 'coordinating care and support' and a 'getting on with it' approach to care. The study highlighted the commitment of sons to their caregiving role and the strong sense of duty that motivated them to provide care. The findings suggested that while many aspects of the caregiving experience such as lack of information and support are gender neutral, there are differences in the caregiving experiences of men and women in how they view their relationship with their parent and in the management of their caregiving role that merit further investigation.

    Résumé Objectif Définir la pratique de la médecine des voyages, présenter les éléments fondamentaux d’une consultation complète préalable aux voyages à des voyageurs internationaux et aider à identifier les patients qu’il vaudrait mieux envoyer en consultation auprès de professionnels de la médecine des voyages. Sources des données Les lignes directrices et les recommandations sur la médecine des voyages et les maladies liées aux voyages publiées par les autorités sanitaires nationales et internationales ont fait l’objet d’un examen. Une recension des ouvrages connexes dans MEDLINE et EMBASE a aussi été effectuée. Message principal La médecine des voyages est une spécialité très dynamique qui se concentre sur les soins préventifs avant un voyage. Une évaluation exhaustive du risque pour chaque voyageur est essentielle pour mesurer avec exactitude les risques particuliers au voyageur, à son itinéraire et à sa destination et pour offrir des conseils sur les interventions les plus appropriées en gestion du risque afin de promouvoir la santé et prévenir les problèmes médicaux indésirables durant le voyage. Des vaccins peuvent aussi être nécessaires et doivent être personnalisés en fonction des antécédents d’immunisation du voyageur, de son itinéraire et du temps qu’il reste avant son départ. Conclusion La santé et la sécurité d’un voyageur dépendent du degré d’expertise du médecin qui offre le counseling préalable à son voyage et les vaccins, au besoin. On recommande à ceux qui donnent des conseils aux voyageurs d’être conscients de l’ampleur de cette responsabilité et de demander si possible une consultation auprès de professionnels de la médecine des voyages pour tous les voyageurs à risque élevé.

  16. End-of-Life Co-residence of Older Parents and Their Sons in Rural China.

    2015-09-01

    This study examined how intergenerational exchanges with sons and daughters predicted older parents' likelihood of co-residing with a son prior to death in a rural area of China's Anhui Province. Our investigation drew on theories of contingent co-residence, modernization, and social exchange, conceptualizing co-residence as having practical and symbolic importance in rural Chinese culture. The sample included 470 older parents, reported as deceased during 2001-2009, and their posthumous informants. We used logistic regression to assess intergenerational support and cohesion as predictors of co-residence with a son just prior to death. Older parents who provided instrumental support to, and received instrumental support from, sons and had better emotional relationships with sons were more likely than their counterparts to co-reside with a son at the end of life. Living with sons demonstrates filial piety for older parents at the end of life, but its realization is sensitive to intergenerational transactions. PMID:26219080

    l'agenda politique du pays. Notre projet de recherche, par le truchement de l'approche des reseaux de politique publique, s'attarde a decrire et a expliquer le processus de la formulation d'une politique particuliere, soit la politique energetique a des fins de protection de l'environnement, elaboree en 1993. Il s'agit de mettre en evidence les facteurs affectant le choix des instruments de ces politiques publiques dans leur contexte national. Ainsi, la question generale de cette recherche est: Comment les phases evolutives de la formation d'un reseau de politique, en l'occurrence le Conseil canadien de l'energie (CCE), menent a des caracteristiques particulieres a ce reseau; et comment celles-ci determinent-elles les types des instruments de politique publique choisis, particulierement ceux de la recente orientation des politiques energetiques canadiennes a des fins environnementales elaborees en 1993? Afin d'atteindre l'objectif de notre recherche, deux facteurs primordiaux sont utilises, soit la circulation de l'information et l'exercice du controle sur les ressources des acteurs. L'analyse des caracteristiques du reseau en fonction des liens forts et des liens faibles autant que la presence ou l'absence des trous structuraux nous permettent de bien identifier les positions des differents acteurs, etatiques et non etatiques, sur le plan de l'information et du controle, qui a leur tour, nous semble-t-il, constituent des facteurs affectant les types des instruments des politiques publiques choisis: instruments substantifs, qui indiquent le degre de l'intervention du gouvernement, et instruments proceduraux, qui mettent plutot l'accent sur le degre de l'influence du gouvernement sur les acteurs non etatiques. L'etude soutient que l'approche des reseaux se distingue notamment par son potentiel a expliquer l'interrelation relative entre idees, interets et institutions, ce qui a son tour est susceptible de permettre une meilleure comprehension des processus de l

  18. Do parents prefer sons in North Korea?

    PubMed

    Goodkind, D

    1999-09-01

    Son preference in South Korea is stronger than anywhere else in the world, yet little is known about such preference in North Korea. Simple indicators of son preference in North Korea are constructed from its 1993 population census and a 1998 survey of child nutrition (conducted in the wake of the recent famine). These indicators include sex ratio at birth, sex ratios of infant and child mortality, and sex ratios of child malnutrition. North Koreans do not evince prenatal discrimination against daughters, a finding that may indicate a lack of prenatal sex-testing technologies. Neither is evidence found of excess female mortality or malnutrition in the postnatal period, during which discrimination requires no special technology. The discrepancy in son preference across the Korean peninsula seems due largely to the socialist agenda pursued in the north following political partition after World War II. An important aspect of that agenda challenged the ancient Confucian ideology presumed to underlie son preference. Apparently, this challenge was more successful in North Korea than in other Asian societies instituting similar political changes, because son preference was not eliminated in China or in Vietnam.

    Heutige Organisationen produzieren und speichern mehr Informationen als je zuvor. Der resultierende Informationsüberfluss, zusammen mit einem Mangel an Qualitätssicherung für das Information Lifecycle Management, führt zu einem unsicheren Status der Informationsqualität in vielen Organisationen. Weiterhin hat sich herausgestellt, dass das Bewerten, Verbessern und Steuern der Informationsqualität ein offenkundig schwieriges Unterfangen ist. Dieses Kapitel stellt ein Modell zur Bewertung und Verbesserung der Information Quality Management Capability Maturity (IQM-Reifegrad) vor. Es wird ein Satz von Kriterien vorgestellt, der aus Literaturrecherche und Fallstudien abgeleitet wurde. Die Reifegradindikatoren werden validiert und in einem mehrstufigen Reifegradmodell durch eine Delphi-Studie gruppiert. Das abgeleitete IQM-Reifegradmodell hilft Organisationen ihre bestehenden Praktiken im IQM zu bewerten und potentielle Lücken und Verbesserungsstrategien zu ermitteln.

Méthodes Nous avons menée une étude à visée descriptive et analytique comportant un volet ré-trospectif du 01 janvier 2006 au 31 décembre 2010 portant sur les paramètres épidémiologiques, cliniques des nouveau-nés hospitalisés et un volet prospectif du 3 octobre 2011 au 29 février 2012 par une entrevue des accompagnateurs des nouveau-nés et des prestataires des services de santé. Résultats Les hospitalisations ont augmenté de 43,65% entre 2006 à 2010 Le taux de mortalité néo-natale hospitalière qui était de 11,04% a connu une réduction moyenne annuelle de 3,95%. L'entrevue a porté sur 110 accompagnateurs et 76 prestataires. La majorité des prestataires (97,44%) et des ac-compagnateurs (88,18%) étaient informés de la stratégie mais n'avait pas une connaissance exacte de sa définition. Les prestataires (94,74%) ont signalé des ruptures de médicaments, consommables médicaux et des pannes d’ appareils de laboratoire et d'imagerie. Parmi les accompagnateurs (89%) disaient être satisfaits des services offerts et (72,89%) trouvaient les coûts abordables mais évoquaient les difficultés du transport. Conclusion: La subvention a amélioré la prise en charge du nou-veau-né mais son optimisation nécessiterait une meilleur information et implication de tous les acteurs.

  9. Becoming the Parent of a GLB Son or Daughter

    GRAFSKY, ERIKA L.

    2014-01-01

    Recent research has documented the importance of parental reactions to disclosure for sexual minority youth (SMY) (e.g., Ryan, Huebner, Diaz, & Sanchez, 2009). The purpose of this study was to develop a deeper understanding of the parent perspective of the disclosure to family experience of SMY ages 14-21. In-depth interviews were conducted with eight parents in the United States who had experienced a child disclose their lesbian, gay, or bisexual (LGB) orientation to them. Constructivist grounded theory and symbolic interaction theory informed the methodology and data analysis for the project. Analysis revealed that the process of becoming the parent of an LGB son or daughter is an appropriate narrative to conceptualize the parental experience of the disclosure to family process. The findings highlight how disclosure introduces new roles into the existing family system, which affects the consideration and interpretation of the salience of particular identities, such as being the parent of an LGB son or daughter. Understanding how parents experience the disclosure to family process - particularly, how they understand and re-envision the meaning of being a parent - is crucial for research and intervention to help families become supportive of SMY. Limitations and suggestions for future research are presented. PMID:25685111

  10. Mate-sampling costs and sexy sons.

    PubMed

    Kokko, H; Booksmythe, I; Jennions, M D

    2015-01-01

    Costly female mating preferences for purely Fisherian male traits (i.e. sexual ornaments that are genetically uncorrelated with inherent viability) are not expected to persist at equilibrium. The indirect benefit of producing 'sexy sons' (Fisher process) disappears: in some models, the male trait becomes fixed; in others, a range of male trait values persist, but a larger trait confers no net fitness advantage because it lowers survival. Insufficient indirect selection to counter the direct cost of producing fewer offspring means that preferences are lost. The only well-cited exception assumes biased mutation on male traits. The above findings generally assume constant direct selection against female preferences (i.e. fixed costs). We show that if mate-sampling costs are instead derived based on an explicit account of how females acquire mates, an initially costly mating preference can coevolve with a male trait so that both persist in the presence or absence of biased mutation. Our models predict that empirically detecting selection at equilibrium will be difficult, even if selection was responsible for the location of the current equilibrium. In general, it appears useful to integrate mate sampling theory with models of genetic consequences of mating preferences: being explicit about the process by which individuals select mates can alter equilibria.

This theory has an AdS/CFT (an equivalence between a conformal field theory in d-1 dimensions and type II string theory defined on an AdS space in d-dimensions) dual in the form of type IIB string theory with AdS{sub 5}×RP{sup 5} geometry. With the aim of studying excited giant graviton dynamics, we construct an orthogonal basis for this sector of the gauge theory in this work. First, we demonstrate that the counting of states, as given by the partition function, and the counting of restricted Schur polynomials match by restricting to a particular class of Young diagram labels. We then give an explicit construction of these gauge invariant operators and evaluate their two-point function exactly. This paves the way to studying the spectral problem of these operators and their D-brane duals.

  12. REFLECT: Logiciel de restitution des reflectances au sol pour l'amelioration de la qualite de l'information extraite des images satellitales a haute resolution spatiale

    NASA Astrophysics Data System (ADS)

    Bouroubi, Mohamed Yacine

    Multi-spectral satellite imagery, especially at high spatial resolution (finer than 30 m on the ground), represents an invaluable source of information for decision making in various domains in connection with natural resources management, environment preservation or urban planning and management. The mapping scales may range from local (finer resolution than 5 m) to regional (resolution coarser than 5m). The images are characterized by objects reflectance in the electromagnetic spectrum witch represents the key information in many applications. However, satellite sensor measurements are also affected by parasite input due to illumination and observation conditions, to the atmosphere, to topography and to sensor properties. Two questions have oriented this research. What is the best approach to retrieve surface reflectance with the measured values while taking into account these parasite factors? Is this retrieval a sine qua non condition for reliable image information extraction for the diverse domains of application for the images (mapping, environmental monitoring, landscape change detection, resources inventory, etc.)? The goals we have delineated for this research are as follow: (1) Develop software to retrieve ground reflectance while taking into account the aspects mentioned earlier. This software had to be modular enough to allow improvement and adaptation to diverse remote sensing application problems; and (2) Apply this software in various context (urban, agricultural, forest) and analyse results to evaluate the accuracy gain of extracted information from remote sensing imagery transformed in ground reflectance images to demonstrate the necessity of operating in this way, whatever the type of application. During this research, we have developed a tool to retrieve ground reflectance (the new version of the REFLECT software). This software is based on the formulas (and routines) of the 6S code (Second Simulation of Satellite Signal in the Solar Spectrum

  13. Is the distant relationship of fathers and homosexual sons related to the sons' erotic preference for male partners, or to the sons' atypical gender identity, or to both?

    Study 1 compared the retrospectively reported father-son relationships of four groups of adult males: (a) Gynephiles (males who erotically prefer physically mature females), (b) androphiles (who prefer physically mature males), (c) a combined group of heterosexual pedophiles and pedohebephiles (the latter being attracted to pubescent as well as prepubescent females), and (d) a combined group of homosexual pedophiles and pedohebephiles (the latter attracted to pubescent as well as prepubescent males). The gynephiles were paid volunteers; the latter three groups were patients. The androphiles, the only group among those compared known to exhibit a measurably greater degree of cross gender identity in childhood, were also the only group to report significantly poorer father-son relations. The homosexual pedo/pedohebephiles, who also prefer male partners but who exhibit typical male gender identity in childhood, did not differ in father-son relations from the gynephiles or the heterosexual pedo/pedohebephiles. Study 2 showed that, within a sample of nonpatient volunteer androphiles, those individuals who reported the greatest degree of cross gender behavior in childhood also tended to report the worst relationships with their fathers. This correlation was replicated within a sample of androphilic patients in Study 3. The consistent pattern of results obtained from these three studies suggests that the emotionally distant relationships of fathers and androphilic sons relate to the sons' atypical childhood gender identity (or observable gender role behavior) rather than to the sons' erotic preference for male partners per se.

  14. Son preference in rural China: patrilineal families and socioeconomic change.

    Murphy, Rachel; Tao, Ran; Lu, Xi

    2011-01-01

    This article draws on a survey conducted in six provinces in summer 2008 to investigate the determinants of son preference in rural China. The analysis confirms the conventional wisdom that son preference is embedded within patrilineal family structures and practices. We extend our analysis by exploring specific aspects of variation within patrilineal family culture. We find that the patrilineal group (clan) composition of villages and family participation in practices such as building ancestral halls and updating genealogies significantly influence son preference. Yet even though son preference is embedded within patrilineal family culture, our analysis suggests that over time the attenuation of son preference is likely. This is because determinants associated with socioeconomic change—for instance, higher levels of education, direct exposure to official policy education materials, higher income (a proxy for rural industrialization), and agricultural mechanization—all attenuate son preference. Being younger and female are also associated with weaker son preference, and both characteristics are likely to interact with education and industrialization to further dilute son preference in the longer term. Nevertheless, our findings suggest that concerted efforts are needed to ameliorate institutional discrimination against rural people in welfare provisioning and in labor markets, and to promote multiple dimensions of gender equality, including in land rights, wage rates, and education.

    2012-01-01

    This study asks parents who have children with Down syndrome how they feel about their lives so that such information could be shared with expectant couples during prenatal counseling sessions. A valid and reliable survey instrument was mailed to 4,924 households on the mailing lists of six non-profit Down syndrome organizations. Of the 2,044 respondents, 99% reported that they love their son or daughter; 97% were proud of them; 79% felt their outlook on life was more positive because of them; 5% felt embarrassed by them; and 4% regretted having them. The parents report that 95% of their sons or daughters without Down syndrome have good relationships with their siblings with Down syndrome. The overwhelming majority of parents surveyed report that they are happy with their decision to have their child with Down syndrome and indicate that their sons and daughters are great sources of love and pride.

    Pour faire face à la crise économique la conception de papier à valeur ajoutée est développée par les industries papetières. Le but de se projet est l'amélioration des techniques actuelles de réticulation des fibres lignocellulosiques de la pâte à papier visant à produire un papier plus résistant. En effet, lors des réactions de réticulation traditionnelles, de nombreuses liaisons intra-fibres se forment ce qui affecte négativement l'amélioration anticipée des propriétés physiques du papier ou du matériau produit. Pour éviter la formation de ces liaisons intra-fibres, un greffage sur les fibres de groupements ne pouvant pas réagir entre eux est nécessaire. La réticulation des fibres par une réaction de « click chemistry » appelée cycloaddition de Huisgen entre un azide et un alcyne vrai, catalysée par du cuivre (CuAAC) a été l'une des solutions trouvée pour remédier à ce problème. De plus, une adaptation de cette réaction en milieux aqueux pourrait favoriser son utilisation en milieu industriel. L'étude que nous désirons entreprendre lors de ce projet vise à optimiser la réaction de CuAAC et les réactions intermédiaires (propargylation, tosylation et azidation) sur la pâte kraft, en milieu aqueux. Pour cela, les réactions ont été adaptées en milieu aqueux sur la cellulose microcristalline afin de vérifier sa faisabilité, puis transférée à la pâte kraft et l'influence de différents paramètres comme le temps de réaction ou la quantité de réactifs utilisée a été étudiée. Dans un second temps, une étude des différentes propriétés conférées au papier par les réactions a été réalisée à partir d'une série de tests papetiers optiques et physiques.

    This Internet-based study examined the association between Israeli parents' attributions regarding the cause of their son's homosexuality and their level of acceptance of their homosexual son. The sample (N = 57) was recruited via Internet Web sites (gay forums and support groups). Findings suggest that more essentialist (versus constructivist) causal attributions were associated with higher levels of parental acceptance. Length of time parents knew of their son's homosexual orientation predicted the degree to which their attributions were essentialist. Implications are discussed. PMID:26177158

    2000-01-01

    The sex of surviving children is an important determinant of reproductive behaviour in South Asia in general and Pakistan in particular. This cohort study evaluates the role of the sex of children on reproductive intentions and subsequent behaviour of women in urban slums of Karachi, Pakistan. The analysis is based on two rounds of surveys conducted in 1990-91 and 1995 of a cohort of married women aged 15-49 years. The results show that pregnancies became increasingly unwanted as the number of surviving sons increased. The sex of surviving children was strongly correlated with subsequent fertility and contraceptive behaviour. However, rather than an exclusive son preference, couples strove for one or more sons and at least one surviving daughter. The policy implications of the link between overt son preference and low status of women are discussed. PMID:10812738

    Two cases of fixed drug eruption, occurring in a mother and son, are presented. The eruption in the mother occurred after she ingested dimenhydrinate or acetylsalicylic acid and in the son after ingestion of either of the above drugs or with "junk" food (cheese crisps). Apart from the drugs, anxiety was found to be an essential factor in the manifestation of the mother's disease. A genetic predisposition would seem to link these cases. PMID:1387603

    Climate data provide a challenging working basis for sonification. Both model data and measured data are assessed in collaboration with the Wegener Center for Climate and Global Change. The multi dimensionality and multi variety of climate data has a great potential for auditory displays. Furthermore, there is consensus on global climate change and the necessity of intensified climate research today in the scientific community and general public. Sonification provides a new means to communicate scientific results and inform a wider audience. SysSon is a user centered auditory platform for climate scientists to analyze data. It gives scientists broader insights by extracting hidden patterns and features from data that is not possible using a single modal visual interface. A variety of soundscapes to chose from lessens the fatigue that comes with repeated and sustained listening to long streams of data. Initial needs assessments and user tests made the work procedures and the terminology of climate scientists clear and informed the architecture of our system. Furthermore, experiments evaluated the sound design which led to a more advanced soundscape and improvement of the auditory display. We present a novel interactive sonification tool which combines a workspace for the scientists with a development environment for sonification models. The tool runs on different operating systems and is released as open source. In the standalone desktop application, multiple data sources can be imported, navigated and manipulated either via text or a graphical interface, including traditional plotting facilities. Sound models are built from unit generator graphs which are enhanced with matrix manipulation functions. They allow us to systematically experiment with elements known from the visual domain, such as range selections, scaling, thresholding, markers and labels. The models are organized in an extensible library, from which the user can choose and parametrize. Importance is

    1995-11-01

    Le sujet de cette these concerne la modelisation numerique du climat regional. L'objectif principal de l'exercice est de developper un modele climatique regional ayant les capacites de simuler des phenomenes de meso-echelle spatiale. Notre domaine d'etude se situe sur la Cote Ouest nord americaine. Ce dernier a retenu notre attention a cause de la complexite du relief et de son controle sur le climat. Les raisons qui motivent cette etude sont multiples: d'une part, nous ne pouvons pas augmenter, en pratique, la faible resolution spatiale des modeles de la circulation generale de l'atmosphere (MCG) sans augmenter a outrance les couts d'integration et, d'autre part, la gestion de l'environnement exige de plus en plus de donnees climatiques regionales determinees avec une meilleure resolution spatiale. Jusqu'alors, les MCG constituaient les modeles les plus estimes pour leurs aptitudes a simuler le climat ainsi que les changements climatiques mondiaux. Toutefois, les phenomenes climatiques de fine echelle echappent encore aux MCG a cause de leur faible resolution spatiale. De plus, les repercussions socio-economiques des modifications possibles des climats sont etroitement liees a des phenomenes imperceptibles par les MCG actuels. Afin de circonvenir certains problemes inherents a la resolution, une approche pratique vise a prendre un domaine spatial limite d'un MCG et a y imbriquer un autre modele numerique possedant, lui, un maillage de haute resolution spatiale. Ce processus d'imbrication implique alors une nouvelle simulation numerique. Cette "retro-simulation" est guidee dans le domaine restreint a partir de pieces d'informations fournies par le MCG et forcee par des mecanismes pris en charge uniquement par le modele imbrique. Ainsi, afin de raffiner la precision spatiale des previsions climatiques de grande echelle, nous developpons ici un modele numerique appele FIZR, permettant d'obtenir de l'information climatique regionale valide a la fine echelle spatiale

  11. The Putative Son's Attractiveness Alters the Perceived Attractiveness of the Putative Father.

    PubMed

    Prokop, Pavol

    2015-08-01

    A body of literature has investigated female mate choice in the pre-mating context (pre-mating sexual selection). Humans, however, are long-living mammals forming pair-bonds which sequentially produce offspring. Post-mating evaluations of a partner's attractiveness may thus significantly influence the reproductive success of men and women. I tested herein the theory that the attractiveness of putative sons provides extra information about the genetic quality of fathers, thereby influencing fathers' attractiveness across three studies. As predicted, facially attractive boys were more frequently attributed to attractive putative fathers and vice versa (Study 1). Furthermore, priming with an attractive putative son increased the attractiveness of the putative father with the reverse being true for unattractive putative sons. When putative fathers were presented as stepfathers, the effect of the boy's attractiveness on the stepfather's attractiveness was lower and less consistent (Study 2). This suggests that the presence of an attractive boy has the strongest effect on the perceived attractiveness of putative fathers rather than on non-fathers. The generalized effect of priming with beautiful non-human objects also exists, but its effect is much weaker compared with the effects of putative biological sons (Study 3). Overall, this study highlighted the importance of post-mating sexual selection in humans and suggests that the heritable attractive traits of men are also evaluated by females after mating and/or may be used by females in mate poaching.

  17. Son Preference, Fertility Decline, and the Nonmissing Girls of Turkey.

    PubMed

    Altindag, Onur

    2016-04-01

    Couples in Turkey exhibit son preference through son-biased differential stopping behavior that does not cause a sex ratio imbalance in the population. Demand for sons leads to lower ratios of boys to girls in larger families but higher ratios in smaller families. Girls are born earlier than their male siblings, and son-biased fertility behavior is persistent in response to decline in fertility over time and across households with parents from different backgrounds. Parents use contraceptive methods to halt fertility following a male birth. The sibling sex composition is associated with gender disparities in health. Among third- or later-born children, female infant mortality is 1.5 percentage points lower if the previous sibling is male. The female survival advantage, however, disappears if the previous sibling is female. Having an older female sibling shifts the gender gap in infant mortality rate by 2 percentage points in favor of males. The improvement in infant mortality is strongest in favor of males who have no older male siblings. PMID:26931324

    1998-01-01

    Cryptorchidism and hypospadias have been related to prenatal estrogen exposure in animal models. Some chemicals used in farming and gardening have been shown to possess estrogenic and other hormone-disrupting effects. Earlier studies have indicated increased risks of urogenital malformations in the sons of pesticide appliers. In the present study, parental occupation in the farming and gardening industry among 6,177 cases of cryptorchidism, 1,345 cases of hypospadias, and 23,273 controls, born live from 1983 to 1992 in Denmark, was investigated in a register-based case-control study. A significantly increased risk of cryptorchidism but not hypospadias was found in sons of women working in gardening (adjusted odds ratio = 1.67; 95% confidence interval, 1.14-2.47). The risks were not increased in sons of men working in farming or gardening. The increased risk of cryptorchidism among sons of female gardeners could suggest an association with prenatal exposure to occupationally related chemicals. PMID:9831539

  3. Supersymmetric vector multiplets in nonadjoint representations of SO(N)

    2007-06-15

    In the conventional formulation of N=1 supersymmetry, a vector multiplet is supposed to be in the adjoint representation of a given gauge group. We present a new formulation with a vector multiplet in the nonadjoint representation of SO(N) gauge group. Our basic algebra is [T{sup I},T{sup J}]=f{sup IJK}T{sup K}, [T{sup I},U{sup i}]=-(T{sup I}){sup ij}U{sup j}, [U{sup i},U{sup j}]=-(T{sup I}){sup ij}T{sup I}, where T{sup I} are the generators of SO(N), while U{sup i} are the new 'generators' in certain nonadjoint real representation R of SO(N). We use here the word generator in the broader sense of the word. Such a representation can be any real representation of SO(N) with the positive definite metric, satisfying (T{sup I}){sup ij}=-(T{sup I}){sup ji} and (T{sup I}){sup [ij|}(T{sup I}){sup |k]l}{identical_to}0. The first nontrivial examples are the spinorial 8{sub S} and conjugate spinorial 8{sub C} representations of SO(8) consistent with supersymmetry. We further couple the system to chiral multiplets and show that a Higgs mechanism can give positive definite (mass){sup 2} to the new gauge fields for U{sup i}. We show an analogous system working with N=1 supersymmetry in 10D, and thereby N=4 system in 4D interacting with extra multiplets in the representation R. We also perform superspace reformulation as an independent confirmation.

  5. Son preference in Indian families: absolute versus relative wealth effects.

    PubMed

    Gaudin, Sylvestre

    2011-02-01

    The desire for male children is prevalent in India, where son preference has been shown to affect fertility behavior and intrahousehold allocation of resources. Economic theory predicts less gender discrimination in wealthier households, but demographers and sociologists have argued that wealth can exacerbate bias in the Indian context. I argue that these apparently conflicting theories can be reconciled and simultaneously tested if one considers that they are based on two different notions of wealth: one related to resource constraints (absolute wealth), and the other to notions of local status (relative wealth). Using cross-sectional data from the 1998-1999 and 2005-2006 National Family and Health Surveys, I construct measures of absolute and relative wealth by using principal components analysis. A series of statistical models of son preference is estimated by using multilevel methods. Results consistently show that higher absolute wealth is strongly associated with lower son preference, and the effect is 20%-40% stronger when the household's community-specific wealth score is included in the regression. Coefficients on relative wealth are positive and significant although lower in magnitude. Results are robust to using different samples, alternative groupings of households in local areas, different estimation methods, and alternative dependent variables. PMID:21302027

    Using the nationally representative India Human Development Survey (IHDS), we create a unique son-father matched data set that is representative of the entire adult male population (aged 20-65) in India. We use these data to document the evolution of intergenerational transmission of educational attainment in India over time, among different castes and states for the birth cohorts of 1940-1985. We find that educational persistence, as measured by the regression coefficient of father's education as a predictor of son's education, has declined over time. This implies that increases in average educational attainment are driven primarily by increases among children of less-educated fathers. However, we do not find such a declining trend in the correlation between educational attainment of sons and fathers, which is another commonly used measure of persistence. To understand the source of such a discrepancy between the two measures of educational persistence, we decompose the intergenerational correlation and find that although persistence has declined at the lower end of the fathers' educational distribution, it has increased at the top end of that distribution.

    We use a nationally representative survey of Indian households (NFHS-3) to conduct the first study that analyzes whether son preference is associated with girls bearing a larger burden of housework than boys. Housework is a non-negligible part of child labor in which around 60 % of children in our sample are engaged. The preference for male offspring is measured by a mother's ideal proportion of sons among her offspring. We show that when the ideal proportion increases from 0 to 1, the gap in the time spent on weekly housework for an average girl compared to that of a boy increases by 2.5 h. We conduct several robustness analyses. First, we estimate the main model separately by caste, religion, and family size. Second, we use a two-stage model to look at participation into housework (as well as other types of work) in addition to hours. Third, we use mother's fertility intentions as an alternative measure of son preference. The analysis confirms that stated differences in male preference translate in de facto differences in girl's treatment. PMID:23914000

    Cette these est dediee a l'etude de l'origine de Titan et de son atmosphere. Dans l'hypothese ou la subnebuleuse de Saturne etait geometriquement mince, le modele de disque turbulent utilise, derive des travaux de Dubrulle (1993), est moins dense que le modele de Prinn et Fegley (1981). De ce fait, les conversions de Co en CH4 et de N2 en NH3 ont ete inhibees dans la subnebuleuse, contrairement a ce qui est couramment admis pour interpreter la presence du methane dans l'atmosphere de Titan. C'est pourquoi nous avons developpe un nouveau scenario de la formation de titan, qui tient compte simultanement des contraintes resultant de la chimie de la subnebuleuse et des abondances de CH4, N2 et CH3D mesurees dans l'atmosphere du satellite. Nous faisons l'hypothese que ces gaz proviennent initialement de la vaporisation du nuage presolaire, qui s'effondra et forma le Soleil et son disque environnant. Lors du refroidissement de la nebuleuse, les volatils auraient ete pieges sous formes de clathrates d'hydrates dans les grains, puis dans les planetesimaux qu'ils formerent. Les planetesimaux hydrates a l'origine de la formation de Titan seraient alors des rescapes de l'effondrement hydsrodynamique de la feeding zone de Saturne. Ce scenario a ete applique aux subnebuleuses de Jupiter et d'Uranus, et a apporte un certain nombre de contraintes sur la formation des satellites reguliers de ces planetes. Le temps et la zone de formation des grains cometaires ont egalement ete estimes dans la nebuleuse solaire. Enfin, l'etude experimentale de la temperature de fusion du dihydrate d'ammoniac dans la gamme des hautes pressions a apporte des nouvelles donnees thermodynamiques qui permettront d'ameliorer les modeles de l'interieur de Titan.

    Nous presentons dans cette these des modeles d'evolution stellaire incorporant la diffusion microscopique de maniere consistante. Pour la premiere fois, on a calcule l'evolution d'etoiles en tenant compte en detail de l'impact des variations d'abondances sur leur structure. Nous utilisons des spectres monochromatiques pour chacun des elements les plus abondants dans un melange solaire pour recalculer l'opacite pour les abondances et les conditions locales dans l'interieur d'une etoile au cours de son evolution. Nos modeles montrent que la diffusion atomique des metaux a un effet important sur les opacites dan les etoiles de plus de 1.3Msolar ou l'abondance du fer et des autres elements du pic du fer varient substantiellement. Ces etoiles, sans rotation ou champ magnetique, sont proches des etoiles de type Fm-Am dans lesquelles on observe une legere surabondance d'elements du pic du fer en plus d'une sous-abondance de calcium, sous-abondance que l'on obtient egalement. Nous obtenons cependant des surabondances depassant un facteur 10 pour les etoiles de plus de 1.4Msolar ce qui suggere qu'il existe un ou plusieurs mecanismes limitant la diffusion microscopique. La surabondance du fer en surface cause une augmentation, qui peut atteindre un facteur sept, de l'opacite a la limite de la zone convective. Ceci cause un accroissement de la temperature effective et de la masse de la zone convective comparativement aux modeles n'incluant que la diffusion de l'helium. Il s'agit la du principal effet de la diffusion sur la structure interne de ces etoiles. La diffusions n'a pas d'influence sur l'evolution de coeur stellaire dans les etoiles significativement plus massives quie le Soleil. Nous avons verife que l'utilisation de modeles consistants avec diffusion n'apporte pas d'amelioration sensible aux modeles solaires. Les forces radiatives calculees a partir des spectres d'OPAL pour les elements du pic du fer representent une fraction importante de la gravite. On obtient des

  13. Adolescent sexual matricide following repetitive mother-son incest.

    PubMed

    Schlesinger, L B

    1999-07-01

    A case of a 16-year-old male who committed a sexual matricide following years of mother-son incest is reported. After murdering his mother by strangulation, which itself was sexually arousing, the youngster engaged in both vaginal and anal necrophilia. The homicide occurred while the perpetrator was in a dissociative state and experiencing what has been referred to as a catathymic crisis: the sudden release of emotionally charged psychic conflict and tension, resulting in extreme violence within an interpersonal bond. Discussion of maternal image and maternal sexual conduct in relationship to the psychosexual development of adolescent males offers insight into the motivation in this extremely rare case.

    Résumé La politique actuelle de lutte contre le sida qui repose sur l’extension de l’accès aux traitements et à la prévention exige qu’une proportion élevée de la population connaisse son statut en matière de VIH. Pour cela, l’OMS a proposé le développement de stratégies communautaires délivrant le dépistage et le conseil au-delà des services de soins, comme le test à domicile ou les campagnes de sensibilisation et dépistage de grande envergure, appliqués en Afrique australe et de l’Est. Pour définir les stratégies pertinentes dans des régions de basse prévalence comme l’Afrique de l’Ouest, les expériences communautaires de promotion du dépistage doivent y être évaluées. Cet article présente une évaluation des campagnes au Burkina Faso du point de vue des usagers. Dans le cadre d’un projet sur les pratiques et l’éthique du dépistage dans quatre pays africains (MATCH), une enquête qualitative spécifique a été menée pendant la campagne de 2008, auprès de personnes ayant fait le test pendant la campagne, ayant fait le test hors campagne ou n’ayant pas fait le test. Les appréciations sont globalement très favorables aux campagnes, notamment à cause de l’information dispensée, l’accessibilité des sites, la gratuité du test, la qualité des services et l’effet d’entrainement. Les limites ou critiques sont essentiellement liées à l’affluence ou à la crainte de ne pas être soutenu en cas de résultat positif. La démarche de recours au test ne fait plus l’objet de suspicion, au moins pendant la campagne. Cette « normalisation » du recours au test et la mobilisation collective facilitent des pratiques en groupe, ce qui peut rendre difficile de garder son statut VIH secret. L’évaluation des campagnes par les usagers les présente comme une opportunité pour accéder facilement au test et pour communiquer à ce sujet dans divers espaces sociaux à partir des informations délivrées sur le VIH

    Helium behavior in a sodium borosilicate glass (SON68) dedicated to the immobilization of high-level nuclear waste is examined. Two experimental approaches on nonradioactive glass specimens are implemented: pressurized helium infusion experiments and {sup 3}He ion implantation experiments. The temperature variation of helium solubility in SON68 glass was determined and analyzed with the harmonic oscillator model to determine values of the energy of interaction E(0) at the host sites (about -4000 J/mol), the vibration frequency (about 1.7 x 10{sup 11} s{sup -1}), and the density of solubility sites (2.2 x 10{sup 21} sites cm{sup -3}). The implantation experiments show that a non diffusive transport phenomenon (i.e., athermal diffusion) is involved in the material when the helium concentration exceeds 2.3 x 10{sup 21} He cm{sup -3}, and thus probably as soon as it exceeds the density of solubility sites accessible to helium in the glass. We propose that this transport mechanism could be associated with the relaxation of the stress gradient induced by the implanted helium profile, which is favored by the glass damage. Microstructural characterization by TEM and ESEM of glass specimens implanted with high helium concentrations showed a homogeneous microstructure free of bubbles, pores, or cracking at a scale of 10 nm.

    Objectives. Strong evidence exists to support an intergenerational cycle of adolescent fatherhood, yet such a cycle has not been studied. We examined whether paternal adolescent fatherhood (i.e., father of study participant was age 19 years or younger when his first child was born) and other factors derived from the ecological systems theory predicted participant adolescent fatherhood. Methods. Data included 1496 young males who were interviewed annually from the National Longitudinal Survey of Youth 1997. Cox regression survival analysis was used to determine the effect of paternal adolescent fatherhood on participant adolescent fatherhood. Results. Sons of adolescent fathers were 1.8 times more likely to become adolescent fathers than were sons of older fathers, after other risk factors were accounted for. Additionally, factors from each ecological domain—individual (delinquency), family (maternal education), peer (early adolescent dating), and environment (race/ethnicity, physical risk environment)—were independent predictors of adolescent fatherhood. Conclusions. These findings support the need for pregnancy prevention interventions specifically designed for young males who may be at high risk for continuing this cycle. Interventions that address multiple levels of risk will likely be most successful at reducing pregnancies among partners of young men. PMID:20075312

    L’anorexie mentale (AM) est une maladie grave qui met la vie en danger et qui fait généralement son apparition pendant l’adolescence. Les données probantes au sujet du traitement optimal de l’AM chez les enfants et les adolescents sont en croissance, mais il reste beaucoup à apprendre. Même si les démarches thérapeutiques actuelles varient au Canada et ailleurs, les données jusqu’à présent indiquent que le traitement familial (TF) est le plus efficace pour les enfants et les adolescents anorexiques. Un élément essentiel du modèle de TF, c’est que les parents sont investis de la responsabilité de rétablir la santé physique de leur enfant et de s’assurer de la reprise complète de son poids. Le médecin qui comprend les principes fondamentaux et la philosophie du TF peut mettre en place les éléments de cette intervention fondée sur des faits probants auprès des jeunes patients anorexiques et de leur famille.

  18. Developpement des betons semi autoplacants a rheologie adaptee pour des infrastructures

    NASA Astrophysics Data System (ADS)

    Sotomayor Cruz, Cristian Daniel

    Au cours des dernières décennies, les infrastructures canadiennes et québécoises comportent plusieurs structures en béton armé présentant des problèmes de durabilité dus aux conditions climatiques sévères, à la mauvaise conception des structures, à la qualité des matériaux, aux types des bétons choisis, aux systèmes de construction ou à l'existence d'événements incontrôlables. En ce qui concerne le choix du béton pour la construction des infrastructures, une vaste gamme de béton divisée en deux principaux types peut être utilisée: le béton conventionnel vibré (BCV) et le béton autoplaçant (BAP). Dans le cas d'un BCV, la consolidation inadéquate par vibration a été un problème récurrent, occasionnant des dommages structuraux. Ceci a conduit à une réduction de la durabilité et à une augmentation du coût d'entretien et de réparation des infrastructures. Rien que l'utilisation d'un BAP a des avantages tels que l'élimination de la vibration, la réduction des coûts de main d'oeuvre et l'amélioration de la qualité des structures, néanmoins, le coût initial d'un BAP par rapport à un BCV ne permet pas encore de généraliser son utilisation dans l'industrie de la construction. Ce mémoire présente la conception d'une nouvelle gamme de béton semi-autoplaçant pour la construction des infrastructures (BSAP-I) exigeant une vibration minimale. Il s'agit de trouver un équilibre optimal entre la rhéologie et le coût initial du nouveau béton pour conférer une bonne performance structurale et économique aux structures. Le programme expérimental établi a premièrement permis d'évaluer la faisabilité d'utilisation des BSAP-I pour la mise en place des piliers d'une infrastructure de pont à Sherbrooke. En plus, l'utilisation d'un plan d'expériences a permis l'évaluation de trois paramètres de formulation sur les propriétés des mélanges de BSAP-I à l'état frais et durci. Finalement, l'évaluation de la performance des

    2015-04-01

    SysSon is a research approach on introducing sonification systematically to a scientific community where it is not yet commonly used - e.g., in climate science. Thereby, both technical and socio-cultural barriers have to be met. The approach was further developed with climate scientists, who participated in contextual inquiries, usability tests and a workshop of collaborative design. Following from these extensive user tests resulted our final software framework. As frontend, a graphical user interface allows climate scientists to parametrize standard sonifications with their own data sets. Additionally, an interactive shell allows to code new sonifications for users competent in sound design. The framework is a standalone desktop application, available as open source (for details see http://sysson.kug.ac.at/) and works with data in NetCDF format.

    An integrated well log, biostratigraphic, and seismic stratigraphic study of Miocene to Recent deltaic sediments deposited in the Nam Con Son Basin offshore from southern Vietnam shows the influence of eustacy and tectonics on sequence development. Sediments consist of Oligocene non-marine rift-basin fill (Cau Formation), early to middle Miocene tide-dominated delta plain to delta front sediments (TB 1.5 to TB 2.5, Due and Thong Formations), and late Miocene to Recent marine shelf sediments (TB. 2.6 to TB 3.1 0, Mang Cau, Nam Con Son, and Bien Dong Formations). Eustacy controlled the timing of key surfaces and sand distribution in the tectonically-quiet early Miocene. Tectonic effects on middle to late Miocene sequence development consist of thick transgressive systems tracts due to basin-wide subsidence and transgression, sand distribution in the basin center, and carbonate sedimentation on isolated fault blocks within the basin. Third-order sequence boundaries (SB) are identified by spore peaks, sand stacking patterns, and channel incision. In the basin center, widespread shale beds with coal occur above sequence boundaries followed by transgressive sandstone units. These TST sandstones merge toward the basin margin where they lie on older HST sandstones. Maximum flooding surfaces (MFS) have abundant marine microfossils and mangrove pollen, a change in sand stacking pattern, and often a strong seismic reflection with downlap. Fourth-order genetic-type sequences are also interpreted. The MFS is the easiest marker to identify and correlate on well logs. Fourth-order SB occur within these genetic units but are harder to identify and correlate.

    2012-01-01

    This study examines the relationship between the husband's preference for a son, sex composition of children and risk of anaemia and underweight among married Indian women. Information was collected regarding 29,517 couples having at least one child in the nationally representative 2005-06 National Family Health Survey of India. The exposures were husband's preference for a son and sex composition of children: sons only, daughters only and mixed. Outcome included maternal underweight and moderate/severe anaemia. Husband's preference for a son was not found to be associated with his wife's risk of anaemia or underweight. Sex composition of the children was modestly associated with increased odds of anaemia among women from households with daughters only as compared with those with sons only [AOR: 1.19; 95% CI 1.04, 1.35]. The findings from this population-based study of socio-cultural norms around preference for a son and married Indian women's nutritional status do not support the hypothesis that husband's preference for sons influences the nutritional status of their wives. However, having daughters only is associated with maternal anaemia for reasons that remain to be established. PMID:22150711

    Objective Parents and adolescents often decide together whether the child should receive human papillomavirus (HPV) vaccine. However, few studies have investigated the dyadic nature of beliefs that affect this process. Method Data came from the 2010 HPV Immunization in Sons (HIS) Study, a national sample of 412 parents and their adolescent sons. We conducted dyadic multivariate logistic regression to test the relationships between parents' and sons' HPV vaccine beliefs and their willingness to have the son receive the vaccine. Results Fewer than half of parents and sons were willing to have the sons receive HPV vaccine (43% and 29%, respectively). Willing parents and sons anticipated greater regret if the son did not receive HPV vaccine but later contracted an HPV infection (parent odds ratio [OR]=1.72, 95% confidence interval [CI]=1.24-2.40; son OR=1.51, 95% CI=1.04-2.19) (both p<.05). Lower concerns about side effects, such as pain and fainting, were also associated with willingness. Conclusion Parents and sons were more willing to have the son receive HPV vaccine if they had higher anticipated regret about potential HPV infection and lower concerns about side effects. Communication campaigns should target these beliefs to increase parents' and sons' willingness to seek HPV vaccination. PMID:26190364

Des etudes anterieures ont deja etabli des modeles bases sur les lois de conservation de la mecanique des fluides basees sur des correlations experimentales qui permettent de predire la decroissance de la concentration et de la vitesse d'un gaz le long de l'axe d'un jet libre vertical. Cette etude s'interesse aux effets de proximite a une surface horizontale parallele sur un jet turbulent. Nous nous interessons a son impact sur l'etendue du champ de la concentration et sur l'enveloppe inflammable en particulier. Cette etude est comparative : l'hydrogene est compare au methane. Ceci permet de degager l'influence des effets de difference de la densite sur le comportement du jet, et de comparer le comportement de l'hydrogene aux correlations experimentales, qui ont ete essentiellement etablies pour le methane. Un modele decrivant l'evolution spatio-temporelle du champ de concentration du gaz dilue est propose, base sur la mecanique des fluides computationnelle. Cette approche permet de varier systematiquement les conditions aux frontieres (proximite du jet a la surface, par exemple) et de connaitre en detail les proprietes de l'ecoulement. Le modele est implemente dans le code de simulations par volumes finis de FLUENT. Les resultats des simulations sont compares avec les lois de similitudes decoulant de la theorie des jets d'ecoulements turbulents libres ainsi qu'avec les resultats experimentaux disponibles. L'effet de la difference des masses molaires des constituantes du jet et des constituantes du milieu de dispersion est egalement etudie dans le contexte du comportement d'echelle de la region developpee du jet.

    Introduction Le but de cette étude était de présenter les premiers résultats de diagnostic anténatal de la trisomie 21 par la technique d'hybridation in situ en fluorescence (FISH) au Maroc et discuter son intérêt dans le diagnostic rapide de cette aneuploïdie. Méthodes Ce travail a été réalisé chez 23 femmes avec des grossesses à haut risque de trisomie 21. La moyenne d’âge des gestantes étaient de 37,43 ans avec des extrêmes de 21 et 43 ans. Toutes étaient musulmanes mariées, mariage légitimé par la Charia, dont trois mariages consanguins, sauf une originaire de la République Démocratique du Congo qui était chrétienne et concubine. La majorité des femmes étaient fonctionnaires et avaient un niveau de scolarisation moyen à élevé. Toutes les patientes ont bénéficié d'une consultation de génétique médicale au cours de laquelle il leur a été donné des informations sur la technique, son intérêt et ses limites. Il s'agit de femmes enceintes qui avaient soit un âge maternel élevé ou des signes d'appel échographiques et/ ou biochimiques. Une des patientes était porteuse d'une translocation robertsonienne t(14;21) équilibrée. Une amniocentèse a été réalisée chez toutes les gestantes et aucun avortement n'a était induit par ce geste invasif. L’âge gestationnel moyen à la première consultation était de 14 semaines d'aménorrhée (SA) et à l'amniocentèse était de 16 SA et 5 jours. L'analyse FISH a été réalisée, après consentement des couples, sur des cellules non cultivées à partir des échantillons de liquides amniotiques, en utilisant des sondes spécifiques du chromosome 21. Résultats Parmi les 23 patientes qui ont bénéficiées d'un diagnostic anténatal de la trisomie 21 par la technique FISH, nous avons pu rassurer 21 d'entre elles, et nous avons détecté deux cas de trisomie 21 fœtal. Conclusion La technique FISH permet un diagnostic anténatal rapide, en moins de 48h, de la trisomie 21 sur

    The parasitic protozoan Toxoplasma gondii has been examined with the electron microscope in order to study the fine structure and the formation of the membranes surrounding the cell. The study of the ultrastructure of the membranes covering the parasite shows the existence of a three-membraned complex. Only the outer membrane is considered to be the plasma membrane; the two membranes below it form an inseparable whole of changeable molecular architecture (modifications in appearance depending on the methods of fixation, local differentiation). During reproduction, which takes place by fission or more often by endogeny, the membranes of the daughter individuals are formed from the membranes of the parent. At first the middle and inner membranes of the parent extend, separating the cytoplasm of the daughter cells from that of the parent. The three-membrane complex of the endozoites is completed at the time of their liberation; the external membrane of the parent covers the leaving endozoites; thus, the plasma membrane of the daughter cells derives also from that of the parent. These findings on the origin and role of limiting membranes during reproduction differ entirely from those described so far for other cells. PMID:5344151

    Régipa, R.

    A partir d'une théorie sur la détermination des formes et des contraintes globales d'un ballon de révolution, ou s'en rapprochant, une nouvelle famille de ballons a été définie. Les ballons actuels, dits de ``forme naturelle'', sont calculés en général pour une tension circonférencielle nulle. Ainsi, pour une mission donnée, la tension longitudinale et la forme de l'enveloppe sont strictement imposées. Les ballons de la nouvelle génération sont globalement cylindriques et leurs pôles sont réunis par un câble axial, chargé de transmettre une partie des efforts depuis le crochet (pôle inférieur), directement au pôle supérieur. De plus, la zone latérale cylindrique est soumise à un faible champ de tensions circonférencielles. Ainsi, deux paramètres permettent de faire évoluer la distribution des tensions et la forme de l'enveloppe: - la tension du câble de liaison entre pôles (ou la longueur de ce câble) - la tension circonférencielle moyenne désirée (ou le rayon du ballon). On peut donc calculer et réaliser: - soit des ballons de forme adaptée, comme les ballons à fond plat pour le bon fonctionnement des montgolfières infrarouge (projet MIR); - soit des ballons optimisés pour une bonne répartition des contraintes et une meilleure utilisation des matériaux d'enveloppe, pour l'ensemble des programmes stratosphériques. Il s'ensuit une économie sensible des coûts de fabrication, une fiabilité accrue du fonctionnement de ces ballons et une rendement opérationnel bien supérieur, permettant entre autres, d'envisager des vols à très haute altitude en matériaux très légers.

  13. Evolution of Hang Son Doong, Vietnam: the largest cave passage in the world

    NASA Astrophysics Data System (ADS)

    Granger, D. E.

    2011-12-01

    Hang Son Doong (HSD), or Mountain River Cave, in the Quang Binh province of Vietnam, is considered to be the largest cave passage in the world. It has continuous widths near 100 m, and heights locally exceeding 200 m in a passage >6.5 km long. HSD is one of many extremely large caves in the tropical karst of the Ke Bang massif, a massively bedded limestone surrounded by metamorphic and clastic sedimentary rocks. Why are these caves so large? Is it because they are young and rapidly formed, or instead did they form slowly in exceptionally strong bedrock? To address these questions it is necessary to examine the style and timing of speleogenesis. Hang Son Doong was formed by an allogenic river sinking along a straight subvertical fault. The cave is formed largely within a brecciated fault zone that extends up to 100 m wide. A relict karst valley indicates that speleogenesis occurred due to wholesale capture of the surface river. The cave pattern is strongly fault-controlled with few branches, consistent with a primarily allogenic rather than distributed recharge. The cave is punctuated by two collapse dolines, one of which impedes discharge today. Massive slackwater deposits perhaps 100 m thick accumulated upstream of this doline collapse, and are overlain by corroded flowstone. To place some time constraints on speleogenesis, two samples were collected for cosmogenic nuclide burial dating with 26Al and 10Be in allogenic quartz. One was from the slackwater deposits, and another from a breccia-filled tributary passage at a fault junction. Both samples postdate cave formation, and can only be used to place minimum ages on the cave. Cosmogenic nuclide concentrations are very low, leading to large uncertainties in the ages. Nonetheless, the burial ages yield some important information. Initial results indicate that the slackwater deposits formed recently, during the past 300 ky. The filled passage, on the other hand, is much older and dates to the Pliocene. Re

  16. SON68 glass dissolution driven by magnesium silicate precipitation

    NASA Astrophysics Data System (ADS)

    Fleury, Benjamin; Godon, Nicole; Ayral, André; Gin, Stéphane

    2013-11-01

    Experimental results are reported on the effect of magnesium silicate precipitation on the mechanisms and rate of borosilicate glass dissolution. Leaching experiments with SON68 glass, a borosilicate containing no Mg, were carried out in initially deionized water at 50 °C with a glass-surface-area-to-solution-volume ratio of 20,000 m-1. After 29 days of alteration the experimental conditions were modified by the addition of Mg to trigger the precipitation of Mg-silicate. Additional experiments were conducted to investigate the importance of other parameters such as pH or dissolved silica on the mechanisms of precipitation of Mg-silicates and their consequences on the glass dissolution rate. Mg-silicates precipitate immediately after Mg is added. The amount of altered glass increases with the quantity of added Mg, and is smaller when silicon is added in solution. A time lag is observed between the addition of magnesium and the resumption of glass alteration because silicon is first provided by partial dissolution of the previously formed alteration gel. It is shown that nucleation does not limit Mg-silicate precipitation. A pH above 8 is necessary for the phase to precipitate under the investigated experimental conditions. On the other hand the glass alteration kinetics limits the precipitation if the magnesium is supplied in solution at a non-limiting rate. The concentration of i in solution was analyzed as well as that of boron. The quantity of i released from the glass is estimated with the assumption that i and B are released congruently at the glass dissolution front. The remained quantity of the element i is then supposed to be in the gel or in the secondary phase. In this paper, we do not make a difference between gel and hydrated glass using the same word 'gel' whereas Gin et al. [40] makes this difference. Recent papers [40,41] discussed about different key issues related to the passivation properties of the alteration layer including the hydrated glass

    2014-01-01

    This study describes a test of the Fathers and Sons Program for increasing intentions to avoid violence and reducing aggressive behaviors in 8- to 12-year-old African American boys by enhancing the parenting skills satisfaction and parenting behaviors of their nonresident fathers. The study included 158 intervention and 129 comparison group families. Structural equation model results indicated that the intervention was effective for improving fathers' parenting skills satisfaction, which was positively associated with sons' satisfaction with paternal engagement. Sons' paternal engagement satisfaction was positively associated with their intentions to avoid violence. Although aggressive behaviors were lower for comparison group sons, the intervention effectively reduced sons' aggressive behaviors indirectly by enhancing fathers' parenting behaviors. Support for family-centered youth violence prevention efforts is discussed. PMID:23746345

  9. Polyandrous females produce sons that are successful at post-copulatory competition.

    2014-03-01

    Some of the genetic benefit hypotheses put forward to explain multiple male mating (polyandry) predict that sons of polyandrous females will have an increased competitive ability under precopulatory or post-copulatory competition via paternally inherited traits, such as attractiveness or fertilization efficiency. Here, we tested these predictions by comparing the competitive ability of sons of experimentally monandrous and polyandrous female bank voles (Myodes glareolus), while controlling for potential material and maternal effects. In female choice experiments, we found no clear preference for sons of either monandrous or polyandrous mothers. Moreover, neither male type was dominant over the other, indicating no advantage in precopulatory male contest competition. However, in competitive matings, sons of polyandrous mothers significantly increased their mating efforts (mating duration, intromission number). In line with this, paternity success was biased towards sons of polyandrous mothers. Because there was no evidence for maternal effects, our results suggest that female bank voles gain genetic benefits from polyandry. PMID:24517341

    Disruptions in FOXP2, a transcription factor, are the only known monogenic cause of speech and language impairment. We report clinical findings for two new individuals with a submicroscopic deletion of FOXP2: a boy with severe apraxia of speech and his currently moderately affected mother. A 1.57 Mb deletion on chromosome 7q31 was detected by array Comparative Genomic Hybridization (aCGH). In addition to FOXP2, the patients’ deletion involves two other genes, MDFIC and PPP1R3A, neither of which has been associated with speech or language disorders. Thus, findings for these two family members provide informative phenotypic information on FOXP2 haploinsufficiency. Evaluation by a clinical geneticist indicated no major congenital anomalies or dysmorphic features. Evaluations by a clinical psychologist and occupational therapist indicated cognitive-linguistic processing and sensorimotor control deficits, but did not support a diagnosis of autism spectrum disorder. Evaluation by clinical and research speech pathologists confirmed that both patients’ speech deficits met contemporary criteria for apraxia of speech. Notably, the patients were not able to laugh, cough, or sneeze spontaneously, replicating findings reported for two other FOXP2 cases and a potential diagnostic sign of nonsyndromic apraxia of speech. Speech severity findings for the boy were not consistent with the hypothesis that loss of maternal FOXP2 should be relatively benign. Better understanding of the behavioral phenotype of FOXP2 disruptions will aid identification of patients, toward an eventual understanding of the pathophysiology of syndromic and nonsyndromic apraxia of speech.

    The boy-to-girl ratio at birth (secondary sex ratio) is around 0.51 in most populations. The sex ratio varies between societies and may be influenced by many factors, such as stress and immunosuppression, age, primiparity, the sex of the preceding siblings and the socioeconomic status of the parents. As parasite infection affects many immunological and physiological parameters of the host, we analyzed the effect of latent toxoplasmosis on sex ratios in humans. Clinical records of 1,803 infants born from 1996 to 2004 contained information regarding the mother’s age, concentration of anti- Toxoplasma antibodies, previous deliveries and abortions and the sex of the newborn. The results of our retrospective cohort study suggest that the presence of one of the most common parasites (with a worldwide prevalence from 20 to 80%), Toxoplasma gondii, can influence the secondary sex ratio in humans. Depending on the antibody concentration, the probability of the birth of a boy can increase up to a value of 0.72, C.I.95 = (0.636, 0.805), which means that for every 260 boys born, 100 girls are born to women with the highest concentration of anti- Toxoplasma antibodies. The toxoplasmosis associated with immunosuppression or immunomodulation might be responsible for the enhanced survival of male embryos. In light of the high prevalence of latent toxoplasmosis in most countries, the impact of toxoplasmosis on the human population might be considerable.

    This autoethnography withdraws from information accumulated through a 10-year period of daily-weekly-monthly descriptive observation-recording (triangulated- parents & house-helper) of caregiving and rehabilitating of our brain injured son (survivor/care-receiver). We present it as an interactive voice of verbal conversation, thoughts, insights, and interpretations. It is delivered as a series of articulation intra-pulsated with our interrogation of societal-cultural-religious perspectives, norms and biases, and aligns with the CAP (Creative Analytical Practices) method of Ellis. This autoethnography glows from the richness of information which encapsulates the challenges confronting us the aging parent caregivers, the gradual incremental mind mending achievement of our son, and the interactive verbalizations and thoughts, of the caregivers, care-receiver, and other persons. The overwhelming mental and physical pain and struggle of the survivor and the aging caregivers and their sense of celebratory-satisfaction with rehabilitation progress are highlighted. Interpretation and valuation of positive and negative responses of other persons provide a critical matrix to this autoethnography. We intend to inform other caregivers and relevant healthcare professionals through this autoethnography. PMID:25763170

    The Kochen-Specker (KS) theorem lies at the heart of the foundations of quantum mechanics. It establishes the impossibility of explaining predictions of quantum theory by any noncontextual ontological model. Spekkens generalized the notion of KS contextuality in [Phys. Rev. A 71, 052108 (2005), 10.1103/PhysRevA.71.052108] for arbitrary experimental procedures (preparation, measurement, and transformation procedures). Interestingly, later on it was shown that preparation contextuality powers parity-oblivious multiplexing [Phys. Rev. Lett. 102, 010401 (2009), 10.1103/PhysRevLett.102.010401], a two-party information theoretic game. Thus, using resources of a given operational theory, the maximum success probability achievable in such a game suffices as a bona fide measure of preparation contextuality for the underlying theory. In this work we show that preparation contextuality in quantum theory is more restricted compared to a general operational theory known as box world. Moreover, we find that this limitation of quantum theory implies the quantitative bound on quantum nonlocality as depicted by the Cirel'son bound.

    This report presents the results of the Community Environmental Response Facilitation Act (CERFA) investigation conducted by The Earth Technology Corporation (TETC) at the Fort Des Moines, a U.S. Government property selected for closure by the Base Realignment and Closure (BRAC) Commission. Under CERFA Federal agencies are required to identify real property that can be immediately reused and redeveloped. Satisfying this objective requires the identification of real property where no hazardous substances or petroleum products, regulated by the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), were stored for one year or more, known to have been released, or disposed. Fort Des Moines is a 53.28-acre site located in Polk County, Iowa, within the city limits of Des Moines. The installation's primary mission is to provide support and shelter for the U.S. Army Reserve. Activities associated with the property that have environmental significance are photographic processing, vehicle maintenance, printing, and fuel storage. TETC reviewed existing investigation documents; U.S. Environmental Protection Agency (USEPA), State, and county regulatory records; environmental data bases; and title documents pertaining to Fort Des Moines during this investigation. In addition, TETC conducted interviews and visual inspections of Fort Des Moines as well as visual inspections and data base searches for the surrounding properties. Information in this CERFA Report was current as of April 1994.

    well expected result from the theory. Although, collimation may be conical, paraboloidal or cylindrical (Part 4), cylindrical collimation is the more likely to occur. The shape of outflows may then be used as a tool to predict physical conditions on the flows or on their source. L'éjection continue de plasma autour d'objets massifs est un phénomène largement répandu en astrophysique, que ce soit sous la forme du vent solaire, de vents stellaires, de jets d'étoiles en formation, de jets stellaires autour d'objets compacts ou de jets extra-galactiques. Cette zoologie diversifiée fait pourtant l'objet d'un commun effort de modélisation. Le but de cette revue est d'abord de présenter qualitativement le développement, depuis leur origine, des diverses théories de vents (Partie 1) et l'inter disciplinarité dans ce domaine. Il s'agit d'une énumération, plus ou moins exhaustive, des idées proposées pour expliquer l'accélération et la morphologie des vents et des jets, accompagnée d'une présentation sommaire des aspects observationnels. Cette partie s'abstient de tout aspect faisant appel au formalisme mathématique. Ces écoulements peuvent être décrits, au moins partiellement, en résolvant les équations magnétohydrodynamiques, axisymétriques et stationnaires. Ce formalisme, à la base de la plupart des théories, est exposé dans la Partie 2. Il permet d'introduire quantitativement les intégrales premières qu'un tel système possède. Ces dernières sont amenées à jouer un rôle important dans la compréhension des phénomènes d'accélération ou de collimation, en particulier le taux de perte de masse, le taux de perte de moment angulaire ou l'énergie du rotateur magnétique. La difficulté de modélisation réside dans l'existence de points critiques, propres aux équations non linéaires, qu'il faut franchir. La nature physique et la localisation de ces points critiques fait l'objet d'un débat important car ils sont la clef de voute de la r

  19. Like daughter, like son? Fertility decline and the transformation of gender systems in the family

    Allendorf, Keera

    2016-01-01

    BACKGROUND An important question for population research is whether fertility decline transforms gender systems. OBJECTIVE This paper contributes to answering this broad question by examining how fertility decline may change the relative value and roles of daughters and sons in families. First, I outline theoretical pathways, suggesting that a key factor is the gender composition of families. As fertility declines, the proportion of families with children of only one gender increases, which may facilitate greater gender symmetry between daughters and sons. Second, I explore how fertility decline may have contributed to the transformation of the relative value and roles of sons and daughters in practice in one place. METHODS The analysis draws primarily on semi-structured interviews with 30 respondents living in one Indian village. This village is located in a district where fertility has declined to at least the replacement level. RESULTS Respondents perceive changes in the gender system, including less son preference, more equal schooling for sons and daughters, more freedom in marriage and premarital relationships, and perhaps greater daughter support of parents in old age. CONCLUSIONS The results describe changes in the relative value, treatment, and behavior of sons and daughters that are consistent with the theorized effects of fertility decline. Future research is needed, however, to determine whether fertility decline makes a causal contribution to changes in the gender system. PMID:27147902

    A detailed analysis of a new experimental practice of the open circuit voltage decay method and of the short circuit current decay method for determining the base minority carrier lifetime and the back surface recombination velocity in solar cells has been performed. The measurements have been made by using the monitoring of a single transient of an operating cell at any level of injection; no power supply is required and a constant illumination level imposes the carrier injection level for normal operating conditions. The theory considers the complete continuity equation including generation and recombination rates of carriers. Precision and sensitivity of the method have been compared. The necessity of a precise knowledge of cell structural parameters have been shown to impose a limitation of the practical use of short-circuit current decay method, to low illumination levels. Cette étude développe une nouvelle méthode expérimentale pour mesurer la durée de vie des porteurs minoritaires dans la base d'une photopile ainsi que la vitesse de recombinaison à son interface arrière. Au cours de la mesure, la photopile est maintenue sous un éclairement constant qui impose le niveau d'injection souhaité. Cette méthode permet d'éliminer les effets néfastes à la mesure, provenant des impédances, propres au composant. Un régime transitoire, provoqué par une variation d'impédance, est étudié au cours de fonctionnements dans des conditions de court-circuit ou de circuit ouvert. L'étude théorique souligne la prise en compte de l'ensemble des phénomènes de recombinaison. L'obtention d'une bonne précision des mesures nécessite, avec une expérimentation rigoureuse, une connaissance précise des paramètres de structure de la photopile étudié. Pour la mesure de la durée de vie des porteurs, la plus grande sensibilité de la méthode en régime transitoire de court-circuit, comparée au régime de circuit ouvert, impose des mesures sous faible

  2. Aggressivity among sons of substance-abusing fathers: association with psychiatric disorder in the father and son, paternal personality, pubertal development, and socioeconomic status.

    An association between childhood aggression and risk for subsequent development of a substance abuse disorder is now well-accepted. In order to better understand the relationship between the presence of paternal substance abuse and aggression among their offspring, 10-12 year old sons of fathers with (n = 34) and without (n = 39) a history of a substance abuse disorder were contrasted on demographics, aggressivity, biological indices of reproductive maturation, and the presence of psychiatric diagnoses. In addition, personality factors, the potential for physical abuse, and psychiatric diagnoses were also ascertained among their fathers. Sons of substance-abusing fathers were found to be significantly more aggressive than sons of nonsubstance abusers. However, they also differed from comparison boys on the basis of SES and school grade attained, as well as the proportion with specific psychiatric disorders. Substance-abusing fathers differed from nonsubstance-abusing men in terms of personality factors and the presence of specific psychiatric disorders, including antisocial personality. They also showed significantly higher child abuse potential scores. A multiple regression analysis of factors contributing to aggression in the boys revealed that a paternal personality factor characterized by stress reactivity, alienation, and aggression was the most robust contributor to aggression among the boys. The boys' diagnoses of attention deficit disorder, oppositional defiant disorder, and lower household socioeconomic status were also significant predictors of aggressivity. Contrary to expectations, paternal, psychiatric diagnoses, substance abuse status, and potential for physical abuse were noncontributory. The results suggest potential mechanisms by which both aggression and risk for substance abuse may be transmitted from father to son. PMID:7639206

    The goal of this study was to determine if parents' beliefs about social norms of human papillomavirus (HPV) vaccination for sons were associated with knowledge of HPV, intention to vaccinate sons, or beliefs about side effects. A cross-sectional, survey-based study of parents with sons was performed in 2010. Fisher's exact tests were used to examine associations between demographics and responses about social norms. Multivariate logistic regression models examined beliefs about social norms of male HPV vaccination and primary outcomes. Few parents agreed that others were vaccinating sons (n = 31/267, 12%), including 1% responding strongly agree and 11% responding agree. Most parents, 52%, disagreed that others were vaccinating (40% disagree, 11% strongly disagree), and 37% chose prefer not to answer regarding others' vaccination practices. Hispanic parents and those with a high school education or less were significantly more likely to choose prefer not to answer than their respective counterparts regarding vaccination norms. In multivariate models, parents agreeing others were vaccinating sons had greater odds of having high knowledge of HPV (adjusted odds ratio [aOR] high vs low knowledge 3.15, 95% confidence interval [CI] 1.13, 8.77) and increased intention to vaccinate sons (n = 243, aOR = 4.41, 95% CI = 1.51, 12.89). Beliefs about side effects were not significantly associated with beliefs about social norms. Parents' beliefs about others' vaccination practices are important with regard to knowledge of HPV and intention to vaccinate sons. Studying how various public messages about HPV vaccine may influence normative beliefs could be relevant to improving vaccination coverage. PMID:25595021

  4. History of son preference and sex selection in India and in the west.

    2003-01-01

    In the history of mankind, there was a time when women dominated the world. In due course of time, as the patriarchal societies evolved, the status of women gradually declined. Sons were preferred to daughters. In India, the Brahmin community promoted such customs and rituals, which gave more and more importance to sons eg. Lighting the funeral pyre of the father was told to be a pre-condition for salvation of his spirit. Similarly, in western civilization also women were considered to be weak. In consonance with such a mind-set man has been trying various techniques for sex-selection since antiquity eg. for acquiring a son choosing a special day, time and posture for sexual intercourse, special diet, charms and amulet and prayers etc. In Vedas also punsavana karma has been described as a technique for acquiring a son. Apart from these techniques, female infanticide has also been used as a way to create a male dominated, son-worshipping society. On development of the technique of ultrasonography as an example of progress of science and technology, man has devised a new way of killing females in womb itself, which has resulted in continuous decline in female: male sex ratio in India. To stop this, Indian Govt. promulgated PNDT Act 1994. But considering the widely prevalent practice of use of various regimen of sex-pre-selection by people as well as unscrupulous medical practitioners, Govt. of India has amended this Act (2002). Still, as authors have found in one of their studies, sex-selection drugs are being used widely by north Indians for getting a son. Here, it should be noted that sex-selection methods are being used in west also. But the perspective is different. There, it is not used for female feticide or for acquiring a son. Rather, it is more an effort towards demonstrating the control of man over the NATURE. PMID:17154116

  8. Dyads of father and son suicide separated by time and circumstances.

    PubMed

    Carson, Henry J

    2010-03-01

    We encountered 2 dyadic suicides among fathers and sons. In the first dyad, the father was a 64-year-old man with complications of heart surgery. He committed suicide with a shotgun. The decedent's son was a 38-year-old man. Five years after his father's death, the son had an argument with his wife. That morning, he drove to the house where his father had lived and inflicted a handgun wound to his head. In the second dyad, the son was a 22-year-old man whose girlfriend left him. He inflicted a shotgun injury to the head. His blood alcohol level was 294 mg/dL. The father of this decedent was a 43-year-old man who 1 year later was despondent after a fight with his girlfriend. He was found dead at home with a single handgun wound to the chest. His blood alcohol level was 173 mg/dL. All 4 suicides appear to have been premeditated and all 4 men used guns. Suicide in a family tends to cause depression and complicate bereavement in survivors more than other types of death. Copycat suicide is well-documented in high-profile cases. The effect of father-son relationships is likely closer and more influential than celebrity suicides. PMID:19935393

  9. Accurate Splicing of HDAC6 Pre-mRNA Requires SON

    PubMed Central

    2015-01-01

    Pre-mRNA splicing requires proper splice site selection mediated by many factors including snRNPs and serine-arginine rich (SR) splicing factors. Our lab previously reported that the SR-like protein SON maintains organization of pre-mRNA splicing factors in nuclear speckles as well as splicing of many human transcripts including mRNAs coding for the chromatin-modifying enzymes HDAC6, ADA and SETD8. However, the mechanism by which SON maintains accurate splicing is unknown. To build tools for understanding SON-dependent pre-mRNA splicing, we constructed a minigene reporter plasmid driving expression of the genomic sequence spanning exons 26 through 29 of HDAC6. Following SON depletion, we observed altered splicing of HDAC6 reporter transcripts that showed exclusion of exons 27 and 28, reflecting the splicing patterns of endogenous HDAC6 mRNA. Importantly, loss of HDAC6 biological function was also observed, as indicated by truncated HDAC6 protein and corresponding absence of aggresome assembly activities of HDAC6 binding-of-ubiquitin zinc finger (BUZ) domain. We therefore propose that SON-mediated splicing regulation of HDAC6 is essential for supporting protein degradation pathways that prevent human disease. PMID:25782155

    Les nodules thyroïdiens sont très fréquents et moins de 10% d'entre eux sont malin. Ils posent un véritable problème diagnostique et thérapeutique surtout par rapport à leur nature bénigne ou maligne. L’étude de certains facteurs cliniques et paracliniques de présomption de malignité permet de bien codifier la stratégie thérapeutique. Le but de ce travail est d’étudier les facteurs prédictifs de malignité des goitres nodulaires et comparer nos résultats à ceux de la littérature. Il s'agit d'une étude rétrospective à propos de 500 cas de goitres nodulaires opérés au service d'Oto-rhino-laryngologie (ORL) et Chirurgie cervico-faciale (CCF) de l'hôpital militaire Avicenne de Marrakech entre 2006 et 2012. Le pourcentage de cancers a été de 6,8%. L’âge moyen de nos patients était de 46 ans, avec une sex-ratio de 5 (F/H). A la palpation cervicale; le caractère dure du nodule a été constaté dans 94,4% des cas de cancer, avec des limites irrégulières dans 64,70% des cas de cancer. Trois nodules étaient fixes et ils étaient tous malins. Les adénopathies cervicales ont été constatées chez 8 malades dont 7 présentaient des cancers. A l’échographie, 61,8% des nodules malins présentaient un aspect hypoéchogène, avec des contours flous dans 88,24% des cas. La vascularisation intra nodulaire était présente dans 35,3% de ces cas des cancers avec des microcalcifications chez 55,9% d'entre eux. Le halo hypoéchogene périnodulaire était incomplet dans 73,5% des cas de cancer. Nos patients étaient en euthyroïdie dans 84,6% des cas. Les facteurs prédictifs de malignité d'un goitre nodulaire, étaient donc dans notre étude d'abord cliniques: l’âge supérieur à 60 ans, la consistance dure du nodule, sa fixité, son caractère irrégulier et mal limité à la palpation, ainsi que la présence d'adénopathie(s) cervicale(s) à l'examen; et échographiques: le caractère hypoéchogène, les limites floues, la présence de

  12. Maternal distancing strategies toward twin sons, one with mild hearing loss: a case study.

    Muñoz-Silva, Alicia; Sánchez-García, Manuel

    2004-01-01

    The authors apply descriptive and sequential analyses to a mother's distancing strategies toward her 3-year-old twin sons in puzzle assembly and book reading tasks. One boy had normal hearing and the other a mild hearing loss (threshold: 30 dB). The results show that the mother used more distancing behaviors with the son with a hearing loss, and thus gave greater encouragement to this son's cognitive development. These results differ from those of previous studies of deaf or hard of hearing children, whose participants generally had severe or profound hearing loss. In those studies, parents of deaf children used more low-level distancing than parents of normally hearing children. The results of the present study are discussed in terms of their implications for the parenting of twins and of children with mild hearing loss. PMID:15646940

    2007-09-01

    This paper explores the factors that influence the practice of induced abortion in a very low fertility society, with particular emphasis on son preference and three distinct religions: Confucianism, Buddhism and Christianity. Using multivariate logistic regression models fitted by the generalized estimating equation (GEE) method, this paper analysed the data collected by the 2000 Korea National Fertility and Family Health Survey of 6348 married women aged 15-49 years with a total of 1217 pregnancy outcomes. The results showed that the likelihood of induced abortions in women with two or more children, compared with those with one child, was significantly influenced by the sex composition of the previous children: odds ratio (OR)=12.71 (95% CI=5.49, 29.42) for women with only son(s), and OR=3.91 (95% CI=1.67, 9.14) for women with only daughter(s). At parity two, women with two sons were much more likely to have induced abortions than women with two daughters (OR=5.88, 95% CI=2.70, 12.85). Although Buddhist women were not significantly different from Confucian women in induced abortion practice, Christian women were much less likely than Confucian women to have an induced abortion (OR=0.39, 95% CI=0.18, 0.88 for women with only sons and OR=0.44, 95% CI=0.24, 0.81 for women with two children). This suggests that even in this very low fertility society, son preference and religious affiliation are significant predictors of women's practice of induced abortion. PMID:17381891

    2016-07-01

    Using 8-year panel data for 1,355 older adults in rural Anhui province, China, this study examined the trajectories and determinants of elder care provided by adult children to their older parents. The results of two-level latent variable growth models showed that trajectories of elder care differed by the gender of children, with an increase in care from sons but a decrease in care from daughters over time. Children's life stages influenced their care provision but differed by gender. Functional impairment of parents and care provided by siblings in the family also affected the care provided by each child. The findings reflect the patrilineal nature of Chinese family systems and demonstrate the linkages between critical life events and caregiving behaviors of adult children. Findings of this study can inform the formulation of elder care policies that meet the needs of families with different structures and at different life stages. PMID:26133805

    2013-01-01

    This paper examines the relationship between two extraordinary artists, father and son--N.C. Wyeth (1882-1945) and Andrew Wyeth (1917-2009)--and their art. N.C. Wyeth, the father, the most famous illustrator of his day, painted scenes full of drama and action, often of men engaged in violent life and death struggles. N.C. was unable to separate from his powerful mother and yearned for his iconic father. He thought himself an artistic failure and dedicated himself to raising his children to be geniuses. The youngest son, Andrew Wyeth, who lived a "secret life," painted scenes often characterized by pathos: bleak and barren landscapes, leaden skies, tire tracks, gray framed houses, desiccated fields, and circling buzzards. In the father-son relationship, we often seen three themes perpetuated developmentally: (1) the son's identification with the innermost conflicts of his father; (2) the yearning for the iconic father of his youth; and (3) a continuation and disavowal of his father's life. These themes are played out in the relationship between Andrew Wyeth and his father. PMID:23965259

    Sex allocation theory predicts that parents are selected to bias their progeny sex ratio (SR) toward the sex that will benefit the most from parental quality. Because parental quality may differentially affect survival of sons and daughters, a pivotal test of the adaptive value of SR adjustment is whether parents overproduce offspring of the sex that accrues larger fitness advantages from high parental quality. However, this crucial test of the long-term fitness consequences of sex allocation decisions has seldom been performed. In this study of the barn swallow (Hirundo rustica), we showed a positive correlation between the proportion of sons and maternal annual survival. We then experimentally demonstrated that this association did not depend on the differential costs of rearing offspring of either sex. Finally, we showed that maternal lifespan positively predicted lifespan of sons but not of daughters. Because in barn swallows lifespan is a strong determinant of lifetime reproductive success, the results suggest that mothers overproduce offspring of the sex that benefits the most from maternal quality. Hence, irrespective of mechanisms causing the SR bias and mother-son covariation in lifespan, we provide strong evidence that sex allocation decisions of mothers can highly impact on their lifetime fitness.

    SUMMARY It has been suspected that cell cycle progression might be functionally coupled with RNA processing. However, little is known about the role of the precise splicing control in cell cycle progression. Here, we report that SON, a large Ser/Arg (SR)-related protein, is a splicing co-factor contributing to efficient splicing of cell cycle regulators. Down-regulation of SON leads to severe impairment of spindle pole separation, microtubule dynamics, and genome integrity. These molecular defects result from inadequate RNA splicing of a specific set of cell cycle-related genes that possess weak splice sites. Furthermore, we show that SON facilitates the interaction of SR proteins with RNA polymerase II and other key spliceosome components, suggesting its function in efficient co-transcriptional RNA processing. These results reveal a mechanism for controlling cell cycle progression through SON-dependent constitutive splicing at suboptimal splice sites, with strong implications for its role in cancer and other human diseases.

  3. Mothers Make a Difference: Mothers Develop Weaker Bonds with Immature Sons than Daughters

    Kulik, Lars; Langos, Doreen; Widdig, Anja

    2016-01-01

    Among mammals, individuals form strong social bonds preferentially with their kin. Differences in these relationships are linked to differential kin availability due to sex-specific dispersal patterns, but there is some indication that differential bonding among sexes already occurs prior to maturation. However, little is known about how these patterns arise during individual development. Here we investigated sex differences in the development of mother-offspring bonds in rhesus macaques (Macaca mulatta). Our results revealed that mothers showed sex-biased bonding toward their offspring. Sons had a distinctly higher probability of receiving aggression from their mothers than did daughters in the first year of life, while no differences were found with respect to affiliative interactions. After the first year, probabilities of all affiliative and aggressive behaviours investigated were higher for daughters than for sons, although generally declining. Furthermore, sons spending less time with their mother and receiving more maternal aggression tended to disperse earlier. The results of our study suggest that mothers influence their bonding strength with offspring by interacting less affiliative with sons than daughters. PMID:27191403

    Edmeades, Jeffrey; Pande, Rohini Prabha; Falle, Tina; Krishnan, Suneeta

    2011-01-01

    This paper explores the ways in which women's sterilisation decisions are influenced by the combination of a preference for male children and a desire for smaller family size among young married women in two urban slums in Bengaluru, India. While both son preference and an emphasis on sterilisation are well-known demographic characteristics of most South Asian countries, relatively little research has been conducted that links the two. We take advantage of a longitudinal survey of 416 unsterilised married women aged 16-25 to explore how having sons and the number of children influence a woman's sterilisation decision. Discrete-time event history techniques are used to estimate two models: the first examines the effect of having sons and number of children separately, and the second examines them in combination in the form of an interaction. The results suggest sterilisation is motivated by son preference mainly at lower parities (three or fewer children) and by concerns about family size at higher parities. Understanding how sterilisation and other reproductive behaviours are influenced by the interaction of family size and sex preferences will help policy-makers and programmers to meet the needs of women while continuing to address discriminatory behaviour against females.

  9. SonTek IQ Plus Velocity Index Discharge Compared to Historical Stage Discharge Curve

    NASA Astrophysics Data System (ADS)

    2014-12-01

    The SonTek IQ Plus bottom-mounted, up-looking Doppler Current meter is relatively new, low profile instrument specifically designed to measure water velocity in open channels through a wide range of conditions and water depth. The predecessor to the IQ, the SonTek Argonaut SW, is a well-established tool for measuring discharge in open channels utilizing a velocity index equation. The IQ builds upon this with velocity indexing capabilities and the addition of two skew beams and the implementation of SmartPulseHD. The SonTek IQ Plus measures velocity with 4-acoustic transducers and the water level using a fifth vertically oriented transducer integrated with a pressure sensor. This improves upon previous and other bottom-mounted, up-looking, acoustic Doppler current meters by measuring the velocity at more points across the channel using its 4-monostatic acoustic transducers. Additionally, the vertically oriented transducer measures the water level and works in conjunction with the pressure sensor to provide a highly accurate water level/stage measurement. The implementation of SmartPulseHD enables the IQ to change ping type and processing technique based on water depth and velocity, in order to provide the most accurate velocity data possible. The IQ was designed specifically for measuring open channel flow in irrigation canals and similar open channels, either by utilizing SonTek's theoretical flow algorithm or using a velocity index equation. The study presented here demonstrates data collected by an IQ installed in an irrigation canal and the discharge computed using a developed index velocity equation. These data are then compared to discharge data determined by a conventional stage discharge curve developed over many years. The data presented demonstrate the capability of the SonTek IQ to compute accurate discharge values based on an index velocity equation that was developed over a relatively short period of time.

    River Son, draining diverse lithologies in the subtropical climate of the peninsular sub-basin of the Ganga basin, is one of the major tributaries of the Ganga River. The chemistry of major ions in the surface water of the Son River was studied in detail to determine various source(s) and processes controlling its water chemistry, seasonal and spatial variations in water chemistry, dissolved fluxes and chemical denudation rate (CDR). The study shows that Ca2+, Mg2+ and HCO 3- are major ionic species in the river water. Most of the measured parameters exhibit a relatively lower concentration in the post-monsoon as compared to pre-monsoon season. The water chemistry highlights the influence of continental weathering aided by secondary contributions from ground water, saline/alkaline soils and anthropogenic activities in the catchment. Results also reflect the dominance of carbonate weathering over silicate weathering in controlling water composition. The Son River delivers about 4.2 million tons of dissolved loads annually to the Ganga River, which accounts for ˜6% of the total annual load carried by the Ganga River to the Bay of Bengal. The average CDR of the Son River is 59.5 tons km -2 yr -1, which is less than the reported 72 tons km -2 yr -1 of the Ganga River and higher than the global average of 36 tons km -2 yr -1. The water chemistry for the pre-monsoon and post-monsoon periods shows a strong seasonal control on solute flux and CDR values. The water chemistry indicates that the Son River water is good to excellent in quality for irrigation and also suitable for drinking purposes.

On a pu conserver 22 fistules soit 70,96% par traitement chirurgical ou endovasculaire, on a confectionné une nouvelle fistule dans 8 cas soit 25,80%, et on a adressé une patiente (3,22%) pour pose d'un cathéter veineux tunnelisé permanent. Les complications des fistules artério-veineuses pour l'hémodialyse chronique sont la principale cause de morbidité chez les patients hémodialysés, il est donc important de s'impliquer lors de leur création, et de donner un maximum d'attention quand ils sont manipulés. Ceci suggère la mise en place d'un programme de surveillance de ces fistules en raison de l'impact des complications sur la morbi-mortalité du patient hémodialysé et sur le plan financier.

    The Blind Cosmology Challenge (BCC) is an effort by the Dark Energy Survey (DES) to test analysis tools for extracting cosmological information using a set of detailed synthetic galaxy catalogs. Here, we describe the creation of these synthetic sky catalogs based on requirements of the optical (DES) and the near-IR VISTA Hemisphere Survey, producing catalogs covering a quarter of the sky to z ˜ 2, with sources complete to r ˜ 25. Starting with a nested set of lightcone outputs of large, N-body simulation, galaxies are assigned to the dark matter distribution using an empirical algorithm that is tunable to match observed evolution of low-order galaxy population properties (counts and spatial clustering) in luminosity-color-density space. Galaxies are lensed by matter along the line of sight (including magnification, shape distortion, and multiple images), using a new algorithm that calculates shear with 3.22 arcsec resolution at galaxy positions in the full catalog. The catalog is well suited to support DES+VISTA joint studies of galaxy clustering, groups and clusters of galaxies, and gravitational lensing, and we highlight their application to the ongoing DES BBCC. Catalogs include ˜320 million galaxies and ˜150 million stars, with realistic colors, shapes and photometric errors. Using the expected DES photometric errors, three independent photometric redshift codes are run on the catalog, two of which produce full probability distributions. The synthetic observable catalog includes object position, magnitudes in the DES and VISTA bands, photometric errors, photometric redshifts, size, ellipticity, for each of ˜ 500 million objects. The galaxy distribution is additionally masked appropriately for the 5000 square degree DES footprint, including the impact of bright stars. In addition, we offer separate catalogs with magnitudes for additional existing and planned surveys, including SDSS, CFHTLS, HSC, LSST, and Euclid.

    L’évolution de la technique opératoire fait de l'urétéroscopie souple –Laser (URSS-L) une méthode efficace et sure dans le traitement des calculs du haut appareil urinaire (HAU). Elle apparait comme une option salvatrice après échec des autres options thérapeutiques. Son coût limite son accessibilité et restreint ses indications dans certains contextes socio-économiques. Nous rapportons l'expérience du service sur les indications, les résultats et les complications de l'URSS-L dans le traitement des calculs du HAU. C'est une étude rétrospective sur 4ans concernant 130 patients ayant des calculs du HAU. Un scanner permettait de déterminer les caractéristiques des calculs avant l'intervention et de faire un contrôle après afin de juger de l'efficacité du traitement. Une analyse statistique évaluait l'influence des différents paramètres des calculs sur l'efficacité de l'intervention. Un suivi était réalisé afin de détecter les complications. L’âge moyen des patients était de 52 ± 17ans. 166 interventions étaient faites en 3 séries. Les indications étaient de première intention dans 50.32% suivi des échecs de LEC. La durée moyenne de l'intervention était de 73min ± 25min pour une taille moyenne des calculs de 13.78mm ± 5mm. Le taux de succès global était de 78.91% (78.71%; 80%; 100%) respectivement après la 1ère, la 2ème et la 3ème série. Aucun paramètre n'influençait significativement le taux de succès. 14.45% de complications était enregistré. L'URSS-L est une méthode aussi efficace que sure dans le traitement des calculs du HAU nous motivant malgré son coût, à élargir ses indications en première intention lorsque les calculs répondent aux critères de choix.

    Mother-son mating (oedipal mating) is practically non-existent in social Hymenoptera, as queens typically avoid inbreeding, mate only early in life and do not mate again after having begun to lay eggs. In the ant genus Cardiocondyla mating occurs among sib in the natal nests. Sex ratios are extremely female-biased and young queens face the risk of remaining without mating partners. Here, we show that virgin queens of Cardiocondyla argyrotricha produce sons from their own unfertilized eggs and later mate with them to produce female offspring from fertilized eggs. Oedipal mating may allow C. argyrotricha queens to found new colonies when no mating partners are available and thus maintains their unusual life history combining monogyny, mating in the nest, and low male production. Our result indicates that a trait that sporadically occurs in solitary haplodiploid animals may evolve also in social Hymenoptera under appropriate ecological and social conditions.

  15. Desire for sons and subsequent fertility in rural India. A 20-year longitudinal study.

    2012-05-01

    This paper compares the desired fertility of rural Indian women in 1987 with their actual fertility in 2007. Seventy-one respondents who stated definite fertility intentions and had fewer children than desired in 1987 were re-interviewed 20 years later, as part of a larger study. The results indicated that these women had fewer children than intended and stopped childbearing once they reached, or approximated, their desired number of sons. The majority had been sterilized, indicating broad acceptance of lower fertility among rural women and the success of India's family planning efforts, although the practice of sex determination seems also to have played a role. These findings echo those of an earlier longitudinal study of reproductive intentions and outcomes in the same community, demonstrating the persistence of son preference in determining reproductive behaviour, even in the context of low overall fertility. The paper concludes with a discussion of the policy and programme implications of the study's findings. PMID:22047888

    Objectives The aim of this prospective study was to investigate whether occupational pesticide exposure during pregnancy causes adverse effects on the reproductive development in the male infants. Design and measurements Pregnant women employed in greenhouses in Denmark were consecutively recruited, and 113 mother–son pairs were included. The mothers were categorized as occupationally exposed (91 sons) or unexposed (22 sons) to pesticides during pregnancy. Testicular position and volume, penile length, and position of urethral opening were determined at 3 months of age using standardized techniques. Concentrations of reproductive hormones in serum from the boys were analyzed. Results The prevalence of cryptorchidism at 3 months of age was 6.2% [95% confidence interval (CI), 3.0–12.4]. This prevalence was considerably higher than among Danish boys born in the Copenhagen area (1.9%; 95% CI, 1.2–3.0) examined by the same procedure. Boys of pesticide-exposed mothers showed decreased penile length, testicular volume, serum concentrations of testosterone, and inhibin B. Serum concentrations of sex hormone-binding globulin, follicle-stimulating hormone, and the luteinizing hormone:testosterone ratio were increased compared with boys of nonexposed mothers. For individual parameters, only the decreased penile length was statistically significant (p = 0.04). However, all observed effects were in the anticipated direction, and a joint multivariate test showed that this finding had a p-value of 0.012. Conclusions Our findings suggest an adverse effect of maternal occupational pesticide exposure on reproductive development in the sons despite current greenhouse safeguards and special measures to protect pregnant women.

    Interleukin-1β (IL-1β) is present throughout the magnocellular neuroendocrine system and co-depletes with oxytocin and vasopressin from the neural lobe during salt-loading. To examine if IL-1β is released from the dendrites/soma of magnocellular neurons during osmotic stimulation, microdialysis adjacent to the supraoptic nucleus (SON) in conscious rats was combined with immunocapillary electrophoresis and laser-induced fluorescence detection to quantify cytokine in 5 min dialysates collected before (0-180 min; basal), and after (180-240 min), hypertonic saline injected s.c. (1.5 M NaCl). Osmotic release of IL-1β was compared after inhibiting local voltage-gated channels for Na+ (tetrodotoxin; TTX) and Ca2+ (cadmium and nickel) or by reducing intracellular Ca2+ stores (thapsigargin). Immunohistochemistry combined with microdialysis was used to localize cytokine sources (IL-1β+) and microglia (OX-42+). Under conditions of microdialysis, basal release of IL-1β+ in the SON area was measurable and stable (pg/ml; mean ± SEM) from 0-60 min (2.2 ± 0.06), 60-120 min (2.32 ± 0.05) and 120-180 min (2.33 ± 0.06), likely originating locally from activated microglia (OX42+; IL-1β+; ameboid, hypertrophied) and magnocellular neurons expressing IL-1β. In response to osmotic stimulation, IL-1β increased progressively in dialysates of the SON area by a mechanism dependent on intracellular Ca2+ stores sensitive to thapsigargin and, similar to dendritic secretion of oxytocin and vasopressin, required local voltage-gated Na+ and Ca2+ channels for activation by osmoregulatory pathways from the forebrain. During osmotic stimulation, neurally dependent release of IL-1β in the SON area likely upregulates osmosensitive cation currents on magnocellular neurons (observed in vitro by others), to facilitate dendritic release of neurohypophysial hormones.

    Height is associated with mortality from many diseases, but it remains unclear whether the association is causal or due to confounding by social factors, genetic pleiotropy,1 or existing ill-health. The authors investigated whether the association of height with mortality is causal by using a son's height as an instrumental variable (IV) for parents’ height among the parents of a cohort of 1,036,963 Swedish men born between 1951 and 1980 who had their height measured at military conscription, aged around 18, between 1969 and 2001. In a two-sample IV analysis adjusting for son's age at examination and secular trends in height, as well as parental age, and socioeconomic position, the hazard ratio (HR) for all-cause paternal mortality per standard deviation (SD, 6.49 cm) of height was 0.96 (95% confidence interval (CI): 0.95, 0.96). The results of IV analyses of mortality from all causes, cardiovascular disease (CVD), respiratory disease, cancer, external causes and suicide were comparable to those obtained using son's height as a simple proxy for own height and to conventional analyses of own height in the present data and elsewhere, suggesting that such conventional analyses are not substantially confounded by existing ill-health.

  1. Son Preference and Children’s Housework: The Case of India

    2013-01-01

    We use a nationally representative survey of Indian households (NFHS-3) to conduct the first study that analyzes whether son preference is associated with girls bearing a larger burden of housework than boys. Housework is a non-negligible part of child labor in which around 60 % of children in our sample are engaged. The preference for male offspring is measured by a mother’s ideal proportion of sons among her offspring. We show that when the ideal proportion increases from 0 to 1, the gap in the time spent on weekly housework for an average girl compared to that of a boy increases by 2.5 h. We conduct several robustness analyses. First, we estimate the main model separately by caste, religion, and family size. Second, we use a two-stage model to look at participation into housework (as well as other types of work) in addition to hours. Third, we use mother’s fertility intentions as an alternative measure of son preference. The analysis confirms that stated differences in male preference translate in de facto differences in girl’s treatment. PMID:23914000

    In 1987, 4 per cent of girls were adopted within China. Why? Unlike infanticide, abandonment rids parents of daughters while preserving the supply of potential brides. In fact, an erstwhile tradition common in Fujian and Jiangxi provinces had parents of sons adopting an infant girl to serve as a future daughter-in-law and household help. Analysing a nationally representative 1992 survey of children, we found that: (1) girl adoptions were concentrated in the above-mentioned provinces; (2) girls were predominantly adopted by families with sons; (3) adopted girls faced substantial disadvantage as measured by school attendance at ages 8-13. In the 1990s, as the sex ratio at birth climbed, were girls aborted rather than abandoned? Observing that in the 2000 census too many girls appear in families with older sons, we estimated that at least 1/25 girls were abandoned in the 1990s, a proportion that in Fujian and Jiangxi may have peaked at 1/10 in 1994.

    Precise knowledge of mutation rate at Y-STRs loci is essential for a correct evaluation of typing results in forensic casework and specially kinship genetic studies. In this study, we have examined 252 confirmed and unrelated father/son sample pairs from Moroccan population using the 17 Y-STR markers DYS19, DYS389I, DYS389II, DYS390, DYS391, DYS392, DYS393, DYS385a, DYS385b, DYS437, DYS438, DYS439, DYS448, DYS456, DYS458, DYS635, and Y-GATA-H4 of the AmpFlSTR Yfiler™ kit used in routine casework. We observed a total of 15 single repeat mutations between fathers and sons as mutational events. Nine mutations resulted in the gain of a repeat in the son and six resulted in a loss of a repeat. The average mutation rate in the studied sample is 3.5×10(-3) (95% CI 2-5.8×10(-3)). Furthermore, Y-STRs mutation occurrence seems to be 4 times more frequent than autosomal STRs mutation in this sample. PMID:23623014

    Pemphigus vulgaris (PV) is a chronic autoimmune bullous disease of the skin and mucous membranes. Although there is some evidence pointing towards a genetic predisposition by some human leukocyte antigen (HLA) genes, familial occurrence of PV is very rare. Most of the familial PV cases so far reported have been in mother and daughter and in siblings. PV in father and son, as presented here, has not been reported in the literature before, except an unconfirmed report. The diagnosis of PV was established by histologic, cytologic studies and enzyme linked immunosorbent assay (ELISA) in Case 1 and by ELISA and BIOCHIP indirect immunofluorescence test in Case 2. The son was responsive to moderate doses of methylprednisolone, with the treatment continuing with tapered doses. The father was in a subclinic condition; consequently, only close follow-up was recommended. HLA typing studies revealed identical HLA alleles of HLA-DR4 (DRB1⁎04) and HLA-DQB1⁎03 in both of our cases; this had been found to be associated with PV in prior studies. Familial occurrences of PV and related HLA genes indicate the importance of genetic predisposition. The first occurrence of confirmed familial PV in father and son is reported here.

    Recent exploration of the south east Nam Con Son Basin, offshore Vietnam, by BP in alliance with Statoil has involved acquisition of new seismic and well data. These new data have allowed re-evaluation of the tectono-stratigraphic development and petroleum geology, and have provided additional constraints on the regional tectonic evolution. The offshore Vietnamese basins have evolved in response to the complex relative motions of Indochina, Peninsular Malaysia, Borneo and the South China Sea during the Cenozoic. On the regional scale these motions have been accommodated by strike-slip fault development, rifting and contraction. In the Nam Con Son Basin these motions have interacted in different ways from the Palaeogene to recent. Two rifting episodes are recognized; a Palaeogene phase dominated by E-W trending extensional faults, and a Miocene phase dominated by N-S to NE-SW trending faults. The structural evolution is complicated by a pulse of mild contraction during the Middle Miocene. The sedimentary fill of the basin evolves from continental fluvio-lacustrine in the Palaeogene through to fully marine following the second phase of rifting in the Miocene. This pulsed structural and stratigraphic evolution has resulted in basinwide deposition of source, reservoir and seal facies, and produced a variety of potential trapping styles. This paper describes the hydrocarbon habitat of the south east Nam Con Son Basin within the context of the regional tectono-stratigraphic model.

    Parents' antisocial behavior is associated with developmental risks for their offspring, but its effects on their children's cognitive ability are unknown. We used linked Swedish register data for a large sample of adolescent men (N = 1,177,173) and their parents to estimate associations between fathers' criminal-conviction status and sons' cognitive ability assessed at compulsory military conscription. Mechanisms behind the association were tested in children-of-siblings models across three types of sibling fathers with increasing genetic relatedness (half-siblings, full siblings, and monozygotic twins) and in quantitative genetic models. Sons whose fathers had a criminal conviction had lower cognitive ability than sons whose fathers had no conviction (any crime: Cohen's d = -0.28; violent crime: Cohen's d = -0.49). As models adjusted for more genetic factors, the association was gradually reduced and eventually eliminated. Nuclear-family environmental factors did not contribute to the association. Our results suggest that the association between men's antisocial behavior and their children's cognitive ability is not causal but is due mostly to underlying genetic factors. PMID:25425060

    Life history theory predicts that mothers should provide their offspring with a privileged upbringing if this enhances their offspring's and their own fitness. In many mammals, high-ranking mothers provide their offspring with a privileged upbringing. Whether dispersing sons gain fitness benefits during adulthood from such privileges (a 'silver spoon' effect) has rarely been examined. In this paper, we show that in the complex, female-dominated society of spotted hyaenas, high-born sons grew at higher rates, were more likely to disperse to clans offering the best fitness prospects, started reproducing earlier and had a higher reproductive value than did lower-born sons. This illustrates the evolutionary importance of maternal effects even in societies in which male size or fighting ability does not influence fitness. By demonstrating for the first time in a non-human mammal that maternal status influences immigration patterns, the study also advances our understanding of two key ecological and evolutionary processes, dispersal and habitat selection.

    Hybrid RANS/LES methods are being increasingly used for turbulent flow simulations in complex geometries. Spalart's detached eddy simulation (DES) model is one of the more popular ones. We are interested in examining the behavior of the Spalart-Allmaras (S-A) Detached Eddy Simulation (DES) model in its ``LES mode.'' The role of the near-wall functions present in the equations is analyzed and an explicit analogy between the S-A and a one-equation LES model based on the sub-grid kinetic energy is presented. A dynamic version of the S-A DES model is proposed based on this connection. Validation studies and results from DES and LES applications will be presented and the effect of the proposed modification will be discussed.

    En 1984 Belavin, Polyakov et Zamolodchikov revolutionnent la theorie des champs en explicitant une nouvelle gamme de theories, les theories quantiques des champs bidimensionnelles invariantes sous les transformations conformes. L'algebre des transformations conformes de l'espace-temps presente une caracteristique remarquable: en deux dimensions elle possede un nombre infini de generateurs. Cette propriete impose de telles conditions aux fonctions de correlations qu'il est possible de les evaluer sans aucune approximation. Les champs des theories conformes appartiennent a des representations de plus haut poids de l'algebre de Virasoro, une extension centrale de l'algebre conforme du plan. Ces representations sont etiquetees par h, le poids conforme de leur vecteur de plus haut poids, et par la charge centrale c, le facteur de l'extension centrale, commune a toutes les representations d'une meme theorie. Les theories conformes minimales sont constituees d'un nombre fini de representations. Parmi celles-ci se trouvent des theories unitaires dont les representation forment la serie discrete de l'algebre de Virasoro; leur poids h a la forme h_{p,q}(m)=[ (p(m+1) -qm)^2-1] (4m(m+1)), ou p,q et m sont des entiers positifs et p+q<= m+1. L'entier m parametrise la charge centrale: c(m)=1 -{6over m(m+1)} avec n>= 2. Ces representations possedent un sous-espace invariant engendre par deux sous-representations avec h_1=h_{p,q} + pq et h_2=h_{p,q} + (m-p)(m+1-q) dont chacun des vecteurs de plus haut poids portent le nom de vecteur singulier et sont notes respectivement |Psi _{p,q}> et |Psi_{m-p,m+1-q}>. . Les theories super-conformes sont une version super-symetrique des theories conformes. Leurs champs appartiennent a des representation de plus haut poids de l'algebre de Neveu-Schwarz, une des deux extensions super -symetriques de l'algebre de Virasoro.

    La surveillance maritime est un domaine d'applications ou l'interet politique et scientifique croit constamment au Canada. Un des outils privilegies pour la surveillance maritime est l'acquisition de donnees radars, par des systemes aeroportes ou spatio-portes (ERS-2, RADARSAT et Envisat). Par leur grande couverture spatiale, ainsi que leur sensibilite a la geometrie de surface, les donnees radars permettent, en autres, la detection de cibles ponctuelles (bateaux), estimation des vents, detection des glaces de mer, ainsi que la detection de deversement d'hydrocarbure. Les limites et les avantages de la detection d'hydrocarbure par acquisitions de donnees radars sont bien connus, mais il reste encore des lacunes au niveau de l'extraction des parametres physiques d'une surface d'hydrocarbure. Ce projet a pour objectif de caracteriser le coefficient de retrodiffusion radar associe a une surface d'hydrocarbure en milieu oceanique, par l'introduction d'un modele thermodynamique d'attenuation de la surface, au modele theorique radar IEM. Le modele global permet de simuler le comportement de sigma° en fonction des proprietes visco-elastiques, ainsi que de l'epaisseur de la couche d'hydrocarbure et en fonction des parametres d'acquisition radar. Le modele developpe fut valide a partir des donnees SIR-C acquises lors d'experimentations controlees. A partir des informations environnementales et du type d'hydrocarbure, notre modele a permis d'estime le contraste d'intensite avec une precision de 1 a 1,5 dB, a la bande C.

  18. ‘Too many girls, too much dowry’: son preference and daughter aversion in rural Tamil Nadu, India

    PubMed Central

    DIAMOND-SMITH, NADIA; LUKE, NANCY; MCGARVEY, STEPHEN

    2013-01-01

    The southern Indian state of Tamil Nadu has experienced a dramatic decline in fertility, accompanied by a trend of increased son preference. This paper reports on findings from qualitative interviews with women in rural villages about their fertility decision-making. Specifically addressed are the reasons behind increasing son preference and the consequences of this change. Findings suggest that daughter aversion, fuelled primarily by the perceived economic burden of daughters due to the proliferation of dowry, is playing a larger role in fertility decision-making than son preference. The desire for a son is often trumped by the worry over having many daughters. Women use various means of controlling the sex of their children, which in this study appear to be primarily female infanticide. It is important to distinguish between son preference and daughter aversion and to examine repercussions of low fertility within this setting. PMID:18821352

  20. L’inhalation de corticostéroïdes est-elle sécuritaire durant la grossesse?

    2014-01-01

    Résumé Question Une femme atteinte d’asthme léger à modéré, autrement en santé, s’est présentée à ma clinique aujourd’hui après avoir appris qu’elle était enceinte. Elle m’a demandé si elle devait continuer à prendre ses corticostéroïdes en inhalation (CSI) et, dans l’affirmative, s’il pourrait y avoir des risques pour son enfant à naître. Quels seraient vos conseils à ce propos? Réponse Compte tenu des données probantes publiées, les CSI devraient être continués durant toute la grossesse à des doses allant de faibles à modérées et suffisantes pour contrôler les symptômes de l’asthme et prévenir les exacerbations. Il faut toutefois être prudent quand il s’agit de doses de plus de 1 000 µg/j (d’équivalent de béclométasone avec chlorofluorocarbures), quoiqu’il soit actuellement questionnable si de telles doses causeraient des effets indésirables. Il faut renseigner de manière continue les patientes sur l’administration appropriée des CSI et l’observance du traitement, y compris durant le premier trimestre. Un bon contrôle de l’asthme réduira la nécessité de doses plus fortes de CSI et de l’exposition possible à des corticostéroïdes systémiques et diminuera ainsi le risque de résultats périnatals ou de grossesse indésirables.

  1. The Tragedy of Hamlet, Son of an Organic Chemist of Denmark

    NASA Astrophysics Data System (ADS)

    Brisbois, Ronald G.

    2004-04-01

    Once faced with structure reactivity relationships in the context of nucleophilic substitution at sp 3 carbon, introductory organic chemistry students must compare and contrast the various attributes and ramifications of S N 2 versus S N 1 reaction pathways. The dramatic (even melodramatic) way in which some students ask such comparative questions inspired a parody of Hamlet's famous to be or not to be soliloquy. Herein, Hamlet (the son of an organic chemist of Denmark) is the surrogate of any and every student as he uses a thoroughly Shakespearian approach to sorting out some of the key distinguishing features of S N 2 versus S N 1 reactions.

  2. Data and Analysis Methods of the Son-O-Mermaid and MERMAID Experiments

    NASA Astrophysics Data System (ADS)

    Simon, J. D.; Simons, F. J.; Nolet, G.

    2014-12-01

    Here we present, for the first time, the results from pilot deployments of the Son-O-Mermaid project, an autonomously drifting, oceangoing data-collection platform that can be cheaply deployed without the need for a costly research vessel, and that records and transmits hydroacoustic signals (with a target of those generated by teleseismic earthquakes) in near real-time. Both deployments employ three identical hydrophones spaced about 70 cm apart at the end of a 700 m long cable attached to a surface buoy that houses electronics, communications, and a GPS location package. The maiden voyage occurred October 8, 2012, in Exuma Bay, Bahamas and returned 25 hours of acoustic data. A second deployment is to take place in September 2014, with near-immediate data relay via Iridium modem. The experimental setup is different from the MERMAID instrument, which sinks to a midcolumn depth and surfaces to transmit waveforms when an event detection algorithm is triggered. MERMAIDs have recorded hundreds of seismic traces from 18 active floats in the Indian and Mediterranean Oceans with a signal-to-noise ratio suitable for global tomography. As with earthquake early-warning studies, both Son-O-Mermaid and MERMAID benefit from rapid and accurate event detection, discrimination, and measurement technology. With this triple purpose in mind we continue to improve methods (in the time-domain, via spectrogram analysis and using wavelets) that we illustrate on the latest and some of the older data, as well. While hydroacoustic data have numerous other applications beyond seismology (whale calls, ice calving, weather patterns, and so on) the Son-O-Mermaid and MERMAID instruments may potentially revolutionize seismic data collection in the oceans. Moreover, in the near future they will be fitted with more or different instruments, becoming multipurpose and multidisciplinary platforms for all types of scientific research in and of the oceans. In seismology we envision a future when the

    The Birmingham Solar-Oscillations Network (BiSON) has been operating with a full complement of six stations since 1992. Over 20 years later, we look back on the network history. The meta-data from the sites have been analysed to assess performance in terms of site insolation, with a brief look at the challenges that have been encountered over the years. We explain how the international community can gain easy access to the ever-growing dataset produced by the network, and finally look to the future of the network and the potential impact of nearly 25 years of technology miniaturisation.

  4. When a son steals money from his mother: courtroom perceptions of elder financial exploitation.

    PubMed

    Golding, Jonathan M; Hodell, Emily C; Dunlap, Emily E; Wasarhaley, Nesa E; Keller, Peggy S

    2013-01-01

    The perception of elder financial exploitation was investigated using community members (N = 104) and undergraduates (N = 143). Participants read an exploitation trial summary; an 85-year-old victim accused her son of stealing her money. Primary results indicated that alleged victims described as healthy rendered more guilty verdicts than those described as having a cognitive deficit; pro-victim judgments were higher for women than men; and younger and older community members' rendered more guilty verdicts than middle-aged mock jurors. The results are discussed in terms of the factors that impact the perception of exploitation in court. PMID:23473296

    Peste des petits ruminants virus causes a highly infectious disease of small ruminants that is endemic across Africa, the Middle East and large regions of Asia. The virus is considered to be a major obstacle to the development of sustainable agriculture across the developing world and has recently been targeted by the World Organisation for Animal Health (OIE) and the Food and Agriculture Organisation (FAO) for eradication with the aim of global elimination of the disease by 2030. Fundamentally, the vaccines required to successfully achieve this goal are currently available, but the availability of novel vaccine preparations to also fulfill the requisite for differentiation between infected and vaccinated animals (DIVA) may reduce the time taken and the financial costs of serological surveillance in the later stages of any eradication campaign. Here, we overview what is currently known about the virus, with reference to its origin, updated global circulation, molecular evolution, diagnostic tools and vaccines currently available to combat the disease. Further, we comment on recent developments in our knowledge of various recombinant vaccines and on the potential for the development of novel multivalent vaccines for small ruminants. PMID:26443889

  12. A trade-off between having many sons and shorter maternal post-reproductive survival in pre-industrial Finland.

    PubMed

    Helle, Samuli; Lummaa, Virpi

    2013-04-23

    A bias in reproduction towards sons, which are energetically more costly than daughters, has been suggested to shorten parental lifespan, but previous results have been mixed. Reproductive costs should be most evident in low rather than high resource settings, and are not expected to be severe in men, because women pay higher direct costs of reproduction. We, therefore, used demographic data from pre-industrial Finland to investigate whether the number of sons and daughters born affected their parents' post-reproductive survival and whether this was related to parent's resource availability. Irrespective of access to resources, mothers, but not fathers, with many sons suffered from reduced post-reproductive survival, and this association decreased as mothers aged. Our results provide evidence that Finnish mothers traded long post-reproductive lifespan for giving birth to many sons. PMID:23445948

  13. Ethnic differences in the mother-son relationship of incarcerated and non-incarcerated male adolescents in the Netherlands

    PubMed Central

    2011-01-01

    Background In the Netherlands, youths of Moroccan origin account for a disproportionately large percentage of the population in juvenile justice institutions. Previous research showed that Moroccan adolescents in pre-trial arrest are characterized by less serious offending behavior (i.e., primarily property-based) and lower levels of mental health problems than native Dutch adolescents in pre-trial arrest. To date, little is known about the parent-child relationship of these adolescents. This study examines the mother-son relationships of Moroccan and native Dutch delinquent adolescents and their association with adolescent delinquency. Methods In the present study, differences in the mother-son relationship characteristics between families of incarcerated (N = 129) and non-incarcerated (N = 324) adolescents were examined, and it was analyzed if these differences between incarcerated and non-incarcerated adolescents were the same for Moroccans and native Dutch. Data collection for the incarcerated sample took place from 2006 to 2008. Comparison data were used of interviews conducted with mothers originating from former larger studies in the general Dutch population. Latent Class Analysis was performed in order to identify types of mother-son relationship. Logistic regression analyses were used to identify the relationships between mother-son relationship types, incarceration and ethnicity. Results A three class model of mother-son relationship types was found: a low-conflict mother-son relationship type, a high-conflict mother-son relationship type, and a neglectful mother-son relationship type. Compared to the native Dutch adolescents, Moroccans (both in the incarcerated and non-incarcerated population) more often showed a neglectful mother-son relationship type. For Moroccans, no differences in mother-son relationship types were found between the incarcerated and non-incarcerated adolescents, whereas considerable differences occurred between the native Dutch

    1999-04-30

    The Sandia National Laboratories (SNL) Data Encryption Standard (DES) Application Specific Integrated Circuit (ASIC) is the fastest known implementation of the DES algorithm as defined in the Federal Information Processing Standards (FIPS) Publication 46-2. DES is used for protecting data by cryptographic means. The SNL DES ASIC, over 10 times faster than other currently available DES chips, is a high-speed, filly pipelined implementation offering encryption, decryption, unique key input, or algorithm bypassing on each clock cycle. Operating beyond 105 MHz on 64 bit words, this device is capable of data throughputs greater than 6.7 Billion bits per second (tester limited). Simulations predict proper operation up to 9.28 Billion bits per second. In low frequency, low data rate applications, the ASIC consumes less that one milliwatt of power. The device has features for passing control signals synchronized to throughput data. Three SNL DES ASICS may be easily cascaded to provide the much greater security of triple-key, triple-DES.

  15. Bartonella henselae bacteremia in a mother and son potentially associated with tick exposure

    PubMed Central

    2013-01-01

    Background Bartonella henselae is a zoonotic, alpha Proteobacterium, historically associated with cat scratch disease (CSD), but more recently associated with persistent bacteremia, fever of unknown origin, arthritic and neurological disorders, and bacillary angiomatosis, and peliosis hepatis in immunocompromised patients. A family from the Netherlands contacted our laboratory requesting to be included in a research study (NCSU-IRB#1960), designed to characterize Bartonella spp. bacteremia in people with extensive arthropod or animal exposure. All four family members had been exposed to tick bites in Zeeland, southwestern Netherlands. The mother and son were exhibiting symptoms including fatigue, headaches, memory loss, disorientation, peripheral neuropathic pain, striae (son only), and loss of coordination, whereas the father and daughter were healthy. Methods Each family member was tested for serological evidence of Bartonella exposure using B. vinsonii subsp. berkhoffii genotypes I-III, B. henselae and B. koehlerae indirect fluorescent antibody assays and for bacteremia using the BAPGM enrichment blood culture platform. Results The mother was seroreactive to multiple Bartonella spp. antigens and bacteremia was confirmed by PCR amplification of B. henselae DNA from blood, and from a BAPGM blood agar plate subculture isolate. The son was not seroreactive to any Bartonella sp. antigen, but B. henselae DNA was amplified from several blood and serum samples, from BAPGM enrichment blood culture, and from a cutaneous striae biopsy. The father and daughter were seronegative to all Bartonella spp. antigens, and negative for Bartonella DNA amplification. Conclusions Historically, persistent B. henselae bacteremia was not thought to occur in immunocompetent humans. To our knowledge, this study provides preliminary evidence supporting the possibility of persistent B. henselae bacteremia in immunocompetent persons from Europe. Cat or flea contact was considered an unlikely

    NASA Astrophysics Data System (ADS)

    Vassoille, R.; Perez, J.

    The aim of the following review is to present the most important studies concerning the physical properties of water-solutes mixtures used in cryobiology. Cryobiology is a branch of biology which deals with the very low temperature behaviour of cells. This technique is developed today in several directions. The creation of banks of cells and perhaps in a short time of small organs, is the purpose of much research in this domain. Before freezing, living cells are generally put in a solution containing one or more solutes. The role of these solutes is to protect the cells against damage due to crystallization of water (cryoprotectors). The mechanisms of cryoprotection are not well known ; nevertheless the vitreous state formation during cooling is often invoked. So, it is possible to avoid crystallization damage such as mechanical strain (due to an increase of volume of about 10 %) and salt effects (due to osmotic pressure). The conditions in which the vitreous state is obtained, maintained during cooling, storage at low temperature and rewarming can be defined by physical studies presented in the following review. Le présent travail est essentiellement une revue bibliographique des principales études physiques qui ont été réalisées avec des solutions de composés habituellement employés en cryobiologie. La cryobiologie est une branche de la biologie qui s'intéresse au comportement des cellules à basse température. Cette discipline est actuellement en plein développement dans des domaines très divers. Son principal but est la création de banques de cellules de plus en plus complexes avec comme perspective la conservation des organes. Les cellules vivantes sont généralement placées avant congélation dans une solution contenant divers composés dont le rôle est de protéger les cellules contre les effets de la cristallisation de l'eau. L'action protectrice de ces cryoprotecteurs est encore mal connue; cependant, la formation d'un état vitreux lors du

    2008-01-01

    This study was aimed at understanding the life of a mother who lost their child in violent circumstances. The methodological proceedings were supported on phenomenology. The study population was constituted by five mothers who had lost its young children for homicide. These homicides occurred different times ranging from 50 days to 10 years. I used as instrument of collection of data open interview the phenomenological method guided by a orienting question. The analysis phenomenology in their discourses showed the comprehension of essential meanings which were systematized in categories: the child's mummification in the memory; the two ways followed by the publicity concerning the death; fondness to spirituality to endure the pain from the child's death; maternal complicity and impunity. The results of this study can contribute to elaboration of intervention proposals close to the mothers in the sense of helping them in the reorganization of their lives after son's death.

  18. The prodigal son: some psychological aspects of Augustine's conversion to Christianity.

    PubMed

    Nauta, Rein

    2008-03-01

    Augustine's conversion is considered exemplary for its Christian testimony. However, the psychological aspects are also relevant, for Augustine's conversion to Christianity was as much inspired by personal and cultural ambitions as by religious convictions. For Augustine, the conversion to the Christian faith spelled a life of asceticism--a life of celibacy, a virtuous and chaste existence, which also offered him a means of escape from the threatening ambiguity of parental relations and a chance to realize the cultural ideal of the civilized philosopher who has subjugated the passions of the flesh. In this paper we explore the psychological dynamics of the absent father, the suffering mother and the prodigal son and the role they played in Augustine's conversion to Christianity. PMID:19105003

    The unambiguous detection of individual solar internal g modes continues to elude us. With the aid of new additions to calibration procedures, as well as updated methods to combine multi-site time series more effectively, the noise and signal detection threshold levels in the low-frequency domain (where the g modes are expected to be found) have been greatly improved. In the BiSON 23-year dataset these levels now rival those of GOLF, and with much greater frequency resolution available, due to the long time series, there is an opportunity to place more constraints on the upper limits of individual g mode amplitudes. Here we detail recent work dedicated to the challenges of observing low-frequency oscillations using a ground-based network, including the role of the window function as well as the effect of calibration on the low frequency domain.

    This study investigates parenting practices and the reported sexual and delinquent behaviors among Thai adolescents, by focusing on the difference between sons and daughters. Data were derived from 420 families whose adolescents aged 13–14 were randomly selected from seven districts in Bangkok using the probability proportional to size (PPS) method. Interviews were conducted with one parent and one adolescent. Female adolescents reported higher levels of parental monitoring, parental rules, communication about sex and parental disapproval of sex, as compared to males. There were no gender differences in the reported sexual and delinquent behaviors among the adolescents. For males, high levels of parental monitoring, greater perception of parent disapproval of sex, and being raised by authoritative parents were associated with less delinquent behaviors. Among females, parental monitoring and parental closeness served as protective factors against sexual and delinquent behaviors. These findings should be useful for developing a body of knowledge and understanding on adolescent rearing among Thai parents. PMID:20420103

    Introduction The task of the caregiver, especially a caregiving mother of a son with a chronic and fatal disease, may interfere with their quality of sleep, sexuality, and some hormone levels. Aim The aim of this study was to evaluate the sexual function and the quality of sleep of caregiving mothers of sons with Duchenne muscular dystrophy (DMD). Methods We evaluated 20 caregiving mothers of sons with DMD and 20 caregiving mothers of sons without any neuromuscular or chronic disease. All of them voluntarily responded to the evaluating questionnaires about their sexuality and their quality of sleep, and gave blood samples to evaluate their hormonal levels. Main Outcome Measures All mothers were evaluated using the questionnaire of Female Sexual Function Index (FSFI) and the Pittsburgh questionnaire (PSQI). The blood samples were tested to determine serum levels of testosterone, estradiol, follicle-stimulating hormone, luteinizing hormone, progesterone, adrenocorticotropic hormone, and cortisol. Results Caregiving mothers of sons with DMD had significantly lower scores in the FSFI questionnaire, suggesting a higher risk for sexual dysfunction. The PSQI demonstrated that these caregiving mothers present increased sleep latency, reduced sleep efficiency, daytime dysfunction, and poor sleep quality. Blood tests showed a rise in cortisol levels, which correlated with the compromised sexuality and quality of sleep. Conclusions This study indicates that caregiving mothers of sons with DMD show major risk for sexual dysfunction and a reduction in their quality of sleep mediated in part by the hormonal changes related to stress.

    In response to concerns from feminists, demographers, bioethicists, journalists, and health care professionals, the Indian government passed legislation in 1994 and 2003 prohibiting the use of sex selection technology and sex-selective abortion. In contrast, South Asian families immigrating to the United States find themselves in an environment where reproductive choice is protected by law and technologies enabling sex selection are readily available. Yet there has been little research exploring immigrant Indian women's narratives about the pressure they face to have sons, the process of deciding to utilize sex selection technologies, and the physical and emotional health implications of both son preference and sex selection. We undertook semi-structured, in-depth interviews with 65 immigrant Indian women in the United States who had pursued fetal sex selection on the East and West coasts of the United States between September 2004 and December 2009. Women spoke of son preference and sex selection as separate though intimately related phenomena, and the major themes that arose during interviews included the sociocultural roots of son preference; women's early socialization around the importance of sons; the different forms of pressure to have sons that women experienced from female in-laws and husbands; the spectrum of verbal and physical abuse that women faced when they did not have male children and/or when they found out they were carrying a female fetus; and the ambivalence with which women regarded their own experience of reproductive "choice." We found that 40% of the women interviewed had terminated prior pregnancies with female fetuses and that 89% of women carrying female fetuses in their current pregnancy pursued an abortion. These narratives highlight the interaction between medical technology and the perpetuation of this specific form of violence against women in an immigrant context where women are both the assumed beneficiaries of reproductive choice

    In this study, the authors examined the extent to which maternal and paternal parenting styles, cognitions, and behaviors were associated with young girls' and boys' more compassionate (prototypically feminine) and more agentic (prototypically masculine) prosocial behaviors with peers. Parents of 133 preschool-aged children reported on their authoritative parenting style, attributions for children's prosocial behavior, and responses to children's prosocial behavior. Approximately 6 months later, children's more feminine and more masculine prosocial behaviors were observed during interactions with unfamiliar peers and reported on by their preschool teachers. Boys and girls did not differ in the observed and teacher-reported measures of prosocial behavior. Compared to other parents, fathers of boys were less likely to express affection or respond directly to children's prosocial behavior. Mothers' authoritative style, internal attributions for prosocial behavior, and positive responses to prosocial behavior predicted girls' displays of more feminine prosocial actions and boys' displays of more masculine prosocial actions toward peers. Relations were similar but weaker for fathers' parenting, and after accounting for mother' scores, fathers' scores accounted for unique variance in only one analysis: Teachers reported more masculine prosocial behavior in boys of fathers who discussed prosocial behavior. Overall, the results support a model of parental socialization of sex-typed prosocial behavior and indicate that mothers contribute more strongly than do fathers to both daughters' and sons' prosocial development.

    Most studies on early childhood parenting include only mothers. Fathers are rarely observed in interaction with their young children, although they play an important role in the socialization of their children. In this study, we observed parenting of mothers and fathers toward their sons and daughters in families with two children, using a within-family approach in a sample with systematically varying family constellations. Participants included 389 families with two children (1 and 3 years of age). Parenting practices were coded during free play using the Emotional Availability Scales (Biringen, 2008). Findings revealed that mothers showed higher levels of sensitivity and lower levels of intrusiveness toward their children than fathers. Furthermore, mothers and fathers were more sensitive and less intrusive toward their oldest child than toward their youngest child. Fathers' higher intrusiveness toward the youngest child was only found in the case of a youngest boy. Child gender was not related to parenting in any of the other analyses. Our results suggest that parent gender is more salient than child gender in the prediction of parenting practices in early childhood. PMID:24635666

    Female preferences for specific male phenotypes have been documented across a wide range of animal taxa, including numerous species where males contribute only gametes to offspring production. Yet, selective pressures maintaining such preferences are among the major unknowns of evolutionary biology. Theoretical studies suggest that preferences can evolve if they confer genetic benefits in terms of increased attractiveness of sons ("Fisherian" models) or overall fitness of offspring ("good genes" models). These two types of models predict, respectively, that male attractiveness is heritable and genetically correlated with fitness. In this meta-analysis, we draw general conclusions from over two decades worth of empirical studies testing these predictions (90 studies on 55 species in total). We found evidence for heritability of male attractiveness. However, attractiveness showed no association with traits directly associated with fitness (life-history traits). Interestingly, it did show a positive correlation with physiological traits, which include immunocompetence and condition. In conclusion, our results support "Fisherian" models of preference evolution, while providing equivocal evidence for "good genes." We pinpoint research directions that should stimulate progress in our understanding of the evolution of female choice. PMID:22946794

  8. Tetracycline-exposed Drosophila melanogaster males produce fewer offspring but a relative excess of sons

    A large diversity of species possesses endosymbionts; these endosymbionts can exhibit mutualistic, parasitic, and commensal relationships with their hosts. Previous work has consistently revealed that depleting endosymbiont titer with antibiotic treatment can significantly alter host fitness and function, particularly with respect to reproductive phenotypes. Although these findings are often interpreted as resulting from the breakdown of highly coevolved symbioses, it is possible that antibiotic treatment itself rather than endosymbiont removal contributes to the observed perturbations in reproductive phenotypes. Here, we investigate the effect of tetracycline treatment on sex ratio and male reproductive fitness using Drosophila melanogaster as a model system. Our results indicate that tetracycline-treated males produce a relative excess of sons. We also find that tetracycline treatment reduces the number of progeny produced by treated males but not treated females. These findings are independent of the effects of tetracycline on Wolbachia titer and implicate the antibiotic itself as mediating these changes. It is yet unclear whether the sex ratio shift and reduction in male reproductive fitness are direct or indirect consequences of tetracycline exposure, and more work is needed to determine the molecular mechanisms by which these disturbances in reproductive phenotypes arise. Our data highlight the importance of considering the potentially confounding effects of antibiotic treatment when investigating the effects of endosymbiont depletion on host phenotypes.

    Several findings suggest that signals from tyrosine kinases are transduced, at least in part, through ras proteins. These findings include (i) blockage of the transforming activity of constitutively active tyrosine kinases by inhibiting ras function and (ii) genetic screens in Caenorhabditis elegans and in Drosophila that identified ras genes as downstream effectors of tyrosine kinases. The recently isolated Drosophila gene Son of sevenless (Sos) is postulated to act as a positive regulatory link between tyrosine kinase and ras proteins by catalyzing exchange of GDP for GTP on ras protein. Such exchange proteins have been reported in extracts of mammalian cells but have not been previously characterized at a molecular level. As Sos appears to function in this role in Drosophila, we sought to isolate a vertebrate counterpart(s). We have characterized two widely expressed murine genes with a high degree of homology to Sos. Hybridization with human DNA and RNA indicates a high degree of conservation of these genes in other vertebrates. Images PMID:1631150

    This article explores the persistence of son preference in a patrilineal, patrilocal society in the midst of fertility decline. Using survey and ethnographic data from Hindu-caste Nepali families in a semiurban village, I analyze which cultural norms regarding reproduction are questioned by contemporary married couples and which remain intact. Despite modest improvements in gender equality, levels of education, and economic conditions, the practical knowledge that daughters will be lost to other lineages and households pressures couples who might otherwise be willing to invest in daughters to continue procreating until they produce a son. Young mothers, therefore, reluctantly admit to needing a son, revealing a discrepancy between their initially stated reproductive ideals and their ultimate behavior. PMID:21466108

    L'interpretation transactionnelle de la mecanique quantique est l'une des plus recentes propositions de description des phenomenes du microcosme. En accord avec les predictions de la mecanique quantique standard, l'interpretation transactionnelle propose une alternative a celle de Copenhague. Son principal avantage est qu'elle permet de visualiser les mecanismes sous-jacents a l'echange d'energie, de quantite de mouvement ou d'autres quantites quantiques entre un emetteur et un absorbeur. Ces echanges sont le resultat, a l'instar de la theorie de l'absorbeur de Wheeler et Feynman, de l'utilisation autant d'ondes avancees que retardees. Bien que l'interpretation transactionnelle n'ait pas attire la plus grande attention scientifique, plusieurs critiques lui ont ete adressees. Dans les annees 1990, differentes experiences a mesure sans interaction ont ete concues. Depuis, il a ete avance que la version originale de l'interpretation transactionnelle pouvait difficilement rendre compte de ce type d'experience et meme qu'elle n'est pas compatible avec le concept d'univers quadridimensionnel. La recherche de ce memoire par article consiste a montrer que lorsque l'on utilise systematiquement l'interpretation transactionnelle en considerant la configuration totale des absorbeurs (incluant l'absorbeur universel), il n'est pas necessaire de faire appel a une hierarchie de transactions comme certains l'ont propose.

    An extrachromosomal factor, termed son-killer (sk), affects the sex ratio in a parasitoid wasp, Nasonia (=Mormoniella ) vitripennis. The factor is maternally transmitted and alters the secondary sex ratio of an infected female through mortality of approximately 80% of the male embryos. No effect on the primary (zygotic) sex ratio is observed. Ninety-five percent of the daughters of an infected female inherit son-killer. The factor can also be transmitted contagiously when the progeny of infected and uninfected females develop simultaneously on a single host. In newly infected strains, the sex ratio effects are equivalent to those in the original. PMID:3988039

Cette différence constitue une signature d'un effet de localisation induit par le champ magnétique sur la topologie mathcal{T}3. Pour des valeurs spécifiques du champ magnétique, du fait des interférences destructives Aharonov-Bohm, la propagation des fonctions d'ondes est limitée à un ensemble fini de cellule du réseau appelé cage. De la dépendance en température des oscillations de période h/e mesurées sur le réseau mathcal{T}3 nous avons tiré une longueur caractéristique qui peut être rattachée au périmètre des cages. Un phénomène inattendu fut l'observation, pour des champs magnétiques plus importants, d'un doublement de fréquence des oscillations. Ces oscillations de période h/2e pouvant avoir une amplitude supérieure aux oscillations de période h/e, une interprétation en terme d'harmonique n'est pas possible. Enfin, l'influence de la largeur électrique des fils constituant le réseau et donc celle du nombre de canaux par brin a été étudiée en réalisant des grilles électrostatique. Les variations de l'amplitude des signaux en h/e et h/2e en fonction de la tension de grille ont été mesurés.

    Cette thèse porte sur l'étude du rayonnement radio auroral kilométrique de Saturne (SKR pour Saturn Kilometric Radiation) observé de façon quasi-continue par les antennes radio de la sonde Cassini depuis son entrée en orbite autour de Saturne en juillet 2004. Comme les rayonnements radio auroraux des autres planètes magnétisées, le SKR est généré sur des lignes de champ magnétique de haute latitude prés des pôles magnétiques. Tirant parti de plusieurs années d'observations, les propriétés macroscopiques du SKR (spectre, polarisation, conjuguaison des sources de chaque hémisphère, mode d'émission) sont déduites par une analyse statistique. Elles montrent en particulier que les caractéristiques de l'émission dépendent fortement de la position de l'observateur. Ceci est une conséquence directe de l'anisotropie du SKR qui engendre de forts effets de visibilité, visibles dans les cartes d'intensité temps-fréquence (arcs, régions d'invisibilité de l'émission). La simulation de ces effets de visibilité apporte de nouvelles contraintes sur les propriétés microscopiques des sources (énergie et distribution des électrons auroraux). Le SKR est connu pour être modulé à une période variable. Une analyse de la variation de cette période radio sur plusieurs années révèle des oscillations à court terme de l'ordre de 20-30 jours dont l'origine est attribuée à la variation de la vitesse caractéristique du vent solaire au niveau de Saturne. Une étude parallèle du rayonnement auroral kilométrique terrestre (AKR), observé lors du survol de la Terre par Cassini en août 1999, met en évidence la découverte d'une modulation diurne semblable à celle du SKR. Enfin, la technique de goniopolarimétrie permet de faire de l'imagerie radio des sources du SKR. L'étude de leur distribution moyenne montre pour la première fois l'existence d'un ovale radio.

    Le cancer colorectal représente un problème majeur de santé publique. Son incidence annuelle mondiale est d’environ un million de cas et la mortalité annuelle est de plus de 500 000 cas par an. Le foie est l’organe le plus fréquemment touché par les métastases. Leur survenue est observée dans 40 à 60% des cas (contemporaines dans 25% des cas). Bien que la résection chirurgicale soit le seul traitement curatif, nombre de patients ne peuvent en bénéficier en raison de l’importante diffusion des métastases hépatiques. Chimiothérapies et biothérapies systémiques sont les options conventionnelles de la prise en charge des métastases hépatiques multiples. C’est dans ces situations cliniques que les thérapies intra-artérielles peuvent jouer un rôle important. Dans cet article, nous présenterons les différentes thérapies endovasculaires applicables aux métastases hépatiques de cancers colorectaux, avec leurs indications, résultats et complications éventuelles.

    2010-01-01

    The lack of success of the "coming out" studies over the last three decades to explain and predict parental responses has motivated an evolutionary psychological reconceptualization. According to this reconceptualization, it was predicted that (a) biological mothers would experience more distress and apply more pressure on gay sons to change than would biological fathers and; (b) obligate investment for fathers on dependent sons would cause fathers to experience more distress and apply more pressure on gay sons to change than it would fathers without this obligate investment. In contrast, a cultural-norm hypothesis predicted that fathers would experience more distress and apply more pressure on gay sons to change than mothers. The majority of predictions were tested using 787 participants from two-biological parent families, who were drawn from a total sample of 891 participants from various family backgrounds. As predicted by the evolutionary hypothesis, biological mothers were reported to have been more distressed and coercive than biological fathers, in spite of a strong, societal expectation to the contrary. Furthermore, the results supported the obligate investment argument for paternal reactions. The model not only correctly explained and predicted parental behavior during coming out, but also was shown to unify within its theoretical framework discrepant results from the literature previously considered inconsistent.

    The Birmingham Solar Oscillations Network (BiSON) has provided high-quality high-cadence observations from as far back in time as 1978. These data must be calibrated from the raw observations into radial velocity and the quality of the calibration has a large impact on the signal-to-noise ratio of the final time series. The aim of this work is to maximize the potential science that can be performed with the BiSON data set by optimizing the calibration procedure. To achieve better levels of signal-to-noise ratio, we perform two key steps in the calibration process: we attempt a correction for terrestrial atmospheric differential extinction; and the resulting improvement in the calibration allows us to perform weighted averaging of contemporaneous data from different BiSON stations. The improvements listed produce significant improvement in the signal-to-noise ratio of the BiSON frequency-power spectrum across all frequency ranges. The reduction of noise in the power spectrum will allow future work to provide greater constraint on changes in the oscillation spectrum with solar activity. In addition, the analysis of the low-frequency region suggests that we have achieved a noise level that may allow us to improve estimates of the upper limit of g-mode amplitudes.

  8. Literature as an exploration of the phenomenology of schizophrenia: disorder and recovery in Denis Johnson's Jesus' Son.

    When read as a fictional psychosis narrative, Jesus' Son, a collection of short stories by Denis Johnson, reveals important elements of the phenomenology of schizophrenia and recovery. It is possible that Jesus' Son, as a work of fiction, may be able to uniquely add depth and nuance to an understanding of the phenomenology of schizophrenia involving a state of psychological fragmentation, an ever-changing interpersonal field and a loss of personal agency. In addition, by following the protagonist in Jesus' Son as he begins to resolve some of his difficulties, the book also offers an individualised account of recovery. The authors detail how the book reveals these insights about schizophrenia and recovery and suggest that these elements are intertwined in such a manner that leads to a profound disruption of self-experience, characterised by a collapse of metacognitive processes. Jesus' Son may add depth to our understanding of the subjective experience of schizophrenia and recovery, and also may serve as one example in which the study of humanities offers an opportunity to explore the human elements in the most profound forms of suffering.

    2012-01-01

    Résumé Objectif Évaluer l’exactitude diagnostique et l’utilité clinique de la dermoscopie pour la détection de mélanomes en pratique familiale. Sources des données Nous avons fait une recension dans les bases de données Ovid MEDLINE (de 1946 à juin 2011), EMBASE, PubMed et Cochrane à l’aide des expressions suivantes en anglais: dermoscopy, dermatoscopy, epiluminescence microscopy, family practice, general practice, primary health care, melanoma, skin neoplasms et pigmented nevus. Pour être prises en considération, les études devaient être des articles de recherche primaire ayant pour sujets des médecins de famille, ainsi que la formation en dermoscopie et son utilisation en tant qu’intervention. La recherche a produit 4 articles qui répondaient aux critères d’inclusion et présentaient des données probantes de niveau I selon la définition du Groupe d’étude canadien sur les soins de santé préventifs. Message principal Dans le milieu de la pratique familiale, la dermoscopie a une sensibilité plus élevée que l’examen à l’œil nu pour la détection des mélanomes sans avoir, généralement, une spécificité moins grande. La dermoscopie aide aussi à accroître le degré de confiance des médecins de famille dans leur diagnostic préliminaire des lésions. L’utilisation de la dermoscopie plutôt que l’examen à l’œil nu augmente la probabilité qu’une lésion jugée cancéreuse le soit de fait et qu’une lésion jugée bénigne le soit en réalité. Conclusion Il est démontré que la dermoscopie est un outil utile et relativement peu coûteux pour la détection des mélanomes en pratique familiale. Cette technique rend les médecins de famille plus confiants dans l’exactitude de leurs demandes de consultations auprès de dermatologues et contribue à diminuer les biopsies inutiles. La dermoscopie peut se révéler plus particulièrement utile dans l’examen des patients à risque élevé de mélanomes, étant donn

    NASA Astrophysics Data System (ADS)

    Hacini, Lyes

    L'assemblage par soudage peut engendrer des contraintes residuelles. Ces contraintes provoquent des fissurations prematurees et un raccourcissement de la duree de vie des composants. Dans ce contexte, le martelage robotise est utilise pour relaxer ces contraintes residuelles. Trois volets sont presentes: le premier est l'evaluation des effets des impacts unitaires repetes sur le champ de contraintes developpe dans des plaques d'acier inoxydable austenitique 304L vierges ou contenant des contraintes residuelles initiales. Dans la deuxieme partie de ce projet, le martelage est applique grace au robot SCOMPI. Les contraintes residuelles induites et relaxees par martelage sont ensuite mesurees par la methode des contours, qui a ete adaptee a cet effet. Dans la troisieme partie, le martelage est modelise par la methode des elements finis. Un modele axisymetrique developpe grace au logiciel ANSYS permet de simuler des impacts repetes d'un marteau elastique sur une plaque ayant un comportement elastoplastique.

    Dysregulation of MLL complex-mediated histone methylation plays a pivotal role in gene expression associated with diseases, but little is known about cellular factors modulating MLL complex activity. Here, we report that SON, previously known as an RNA splicing factor, controls MLL complex-mediated transcriptional initiation. SON binds to DNA near transcription start sites, interacts with menin, and inhibits MLL complex assembly, resulting in decreased H3K4me3 and transcriptional repression. Importantly, alternatively spliced short isoforms of SON are markedly upregulated in acute myeloid leukemia. The short isoforms compete with full-length SON for chromatin occupancy but lack the menin-binding ability, thereby antagonizing full-length SON function in transcriptional repression while not impairing full-length SON-mediated RNA splicing. Furthermore, overexpression of a short isoform of SON enhances replating potential of hematopoietic progenitors. Our findings define SON as a fine-tuner of the MLL-menin interaction and reveal short SON overexpression as a marker indicating aberrant transcriptional initiation in leukemia. PMID:26990989

Au second niveau les reponses des eleves de la population indiquent une conception de la dynamique cardio-vasculaire axee d'abord sur le coeur, laissant aux vaisseaux un role passif de canaux. Ces reponses indiquent egalement que la dynamique circulatoire est reduite a une sequence d'etapes ponctuelles sans relation les unes avec les autres. Au troisieme niveau les reponses des eleves de la population font etat d'une conception du controle qui privilegie la satisfaction de besoins locaux, sans relation systemique. Nos resultats suggerent que les eleves de notre echantillon affichent une plus grande concordance avec l'expert pour les questions du premier niveau (70%) que pour les niveaux II (54%) et III (50%). Notre analyse des donnees revele que l'accord avec l'expert est eleve lorsque la questions touchent la description des structures et la definition de leurs roles et plus faible lorsque les questions touchent la dynamique et le controle. Il existerait donc un niveau de formulation qui correspond a la description de structures et un autre niveau qui recoupe toute la dynamique de la circulation et son controle. Du point de vue didactique lanalyse des donnees suggere que nous ne retrouvons pas une correspondance entre les niveaux de formulation didactique et les conceptions des eleves.

  19. Kauffman knot invariant from SO(N) or Sp(N) Chern-Simons theory and the Potts model

    2010-06-15

    The expectation value of Wilson loop operators in three-dimensional SO(N) Chern-Simons gauge theory gives a known knot invariant: the Kauffman polynomial. Here this result is derived, at the first order, via a simple variational method. With the same procedure the skein relation for Sp(N) are also obtained. Jones polynomial arises as special cases: Sp(2), SO(-2), and SL(2,R). These results are confirmed and extended up to the second order, by means of perturbation theory, which moreover let us establish a duality relation between SO({+-}N) and Sp({+-}N) invariants. A correspondence between the first orders in perturbation theory of SO(-2), Sp(2) or SU(2) Chern-Simons quantum holonomy's traces and the partition function of the Q=4 Potts model is built.

  20. Alteration kinetics of the glass-ceramic zirconolite and role of the alteration film Comparison with the SON68 glass

    NASA Astrophysics Data System (ADS)

    2007-06-01

    The glass-ceramic zirconolite is being considered for specific conditioning of plutonium or the minor actinides. The actinides are distributed throughout the zirconolite crystals and the residual glass phase. Since zirconolite alteration is extremely limited, actinide release from the glass-ceramic material is mainly attributable to alteration of the residual glass. Specimens corresponding to the residual glass phase alone were therefore altered under different conditions to compare their kinetics with the one of the SON68 glass (inactive R7T7 type glass). Glass-ceramic zirconolite presents a more important rate decrease occuring more rapidly and that induces a quantity of glass altered at least 10 times as small as for SON68 glass. This slowdown of the alteration rate is attributed to the formation of an alteration film that has been the subject of a specific study. We have in particular identified a dense phase enriched in titanium and neodymium that probably influences deeply the kinetics.

    We extend the physics case for a new high-energy, ultra-high statistics neutrino scattering experiment, NuSOnG (Neutrino Scattering On Glass) to address a variety of issues including precision QCD measurements, extraction of structure functions, and the derived Parton Distribution Functions (PDFs). This experiment uses a Tevatron-based neutrino beam to obtain a sample of Deep Inelastic Scattering (DIS) events which is over two orders of magnitude larger than past samples. We outline an innovative method for fitting the structure functions using a parameterized energy shift which yields reduced systematic uncertainties. High statistics measurements, in combination with improved systematics, will enable NuSOnG to perform discerning tests of fundamental Standard Model parameters as we search for deviations which may hint of 'Beyond the Standard Model' physics.

    La biopsie radioguidée constitue une alternative à la biopsie chirurgicale invasive et à la cytologie pour le diagnostic des tumeurs pédiatriques. L'intérêt de notre étude est d’évaluer la valeur diagnostique des biopsies radioguidées examinées au laboratoire d'anatomopathologie de l'hôpital d'Enfants de Rabat (HER). L’étude a porté sur 78 biopsies radioguidées recueillies dans notre laboratoire entre janvier 2008 et décembre 2011. l’âge moyen des patients était de 5 ans et 10 mois avec une prédominance masculine (65,4%). La tumeur était abdominale dans 80% des cas, thoracique dans 15% cas, thoracique et abdominale dans 2,5% et sacrée dans 1,2%. Les biopsies étaient écho-guidées dans 90% des cas et scannoguidées dans 10% des cas. Le diagnostic histopathologique était posé dans 89% des cas. L'immuno-histochimie a été indiquée dans 35% des cas. Les diagnostics les plus fréquents étaient: tumeurs neuroblastiques (42 cas), lymphomes non hodgkiniens (10 cas), rhabdomyosarcomes (6 cas), autres (sarcome d'Ewing, néphroblastomes, tumeur myofibroblastique inflammatoire, maladies de Hodgkin, leucémie aiguë, hépatoblastome et ostéosarcome). Dans notre série, la biopsie radioguidée a permis un diagnostic histopathologique certain dans 89% des cas. Elle nécessite une étroite collaboration entre clinicien, radiologue et anatomopathologiste pour discuter son indication, afin de diminuer le nombre de biopsies peu ou non représentatives.

  4. An X-Linked Sex Ratio Distorter in Drosophila simulans That Kills or Incapacitates Both Noncarrier Sperm and Sons

    Genomic conflict occurs when a genomic component gains a reproductive advantage at the expense of the organism as a whole. X-linked segregation distorters kill or incapacitate Y-bearing sperm, thereby gaining a transmission advantage but also reducing male fertility and generating a female-biased sex ratio. When some damaged, Y-bearing sperm survive and fertilize eggs, then the segregation distortion phenotype could be expanded by harming or killing sons in the next generation. X-linked son-killers are predicted by theory to be favored by natural selection and evolve when brothers and sisters compete for shared limiting resources and/or when brothers reduce the inclusive fitness of their sisters via sib-mating—a phenomenon called SA-zygotic drive. Here I develop and use a process-of-elimination screen to show that an unclassified X-linked sex ratio distorter (skew) in Drosophila simulans kills or incapacitates noncarrier sperm and also kills a substantial proportion of sons, i.e., it has both a segregation distortion and a SA-zygotic drive phenotype. There are three unique X-linked segregation distorters known to occur in D. simulans named Winters, Durham, and Paris. Autosomal-dominant suppressors of Winters (Nmy) and Durham (Tmy) failed to suppress skew. A Y-linked suppressor of Paris, however, did suppress skew, and a recombination test failed to detect recombinants between these two sex ratio distorters, indicating that they are tightly linked and plausibly identical or allelic. Son-killing may be an important yet unrecognized component of other X-linked segregation distorters. PMID:25081980

    A theoretical analysis of quartz accelerometers is performed to determine their optimal mechanical and sensitivity performances. A general analytical model is used to investigate the parameters and their effects on the sensitivity of these sensors. The analysis of physical characteristics shows that feasibility and performances depend on three factors such as dimensions of the quartz plate, quantity of holders located at the crystal edge and location of these holders with respect to the crystal's crystallographic reference. This study is applied to various design sensors with different supporting quartz crystal. The conditions on parameters are given to achieve optimum performances. Une étude théorique de la sensibilité des capteurs d'accélération à cristal de quartz est présentée. Son but est d'optimiser les performances mécaniques et métrologiques de ces capteurs. Les paramètres sensibles sont mis en évidence. L'analyse des caractéristiques physiques démontre que la faisabilité et les performances des accéléromètres à quartz dépendent, pour une coupe donnée du cristal, de trois facteurs : les dimensions de la lame de quartz, le nombre de liaisons à la périphérie du cristal et la position de ces liaisons par rapport à la référence cristallographique. L'étude est appliquée aux cas des capteurs bipodes, multipodes et monopodes. Pour chaque type de capteur, les valeurs des paramètres sensibles correspondant aux performances optimales sont précisées.

    Peste des petits ruminants virus (PPRV) causes a severe contagious disease of sheep and goats and has spread extensively through the developing world. Because of its disproportionately large impact on the livelihoods of low-income livestock keepers, and the availability of effective vaccines and good diagnostics, the virus is being targeted for global control and eventual eradication. In this review we examine the origin of the virus and its current distribution, and the factors that have led international organizations to conclude that it is eradicable. We also review recent progress in the molecular and cellular biology of the virus and consider areas where further research is required to support the efforts being made by national, regional, and international bodies to tackle this growing threat.
