    2005-01-01

    Nous ne sommes pas à l'abri de nouveaux tchernobyls. L'humanité va s'enrichir de milliards d'individus dans les décennies à venir. L'énergie nucléaire est donc plus que jamais indispensable. Mais l'accident de Tchernobyl aura fait des dizaines de milliers de morts. Ce livre permet de comprendre les enjeux du nucléaire civil, mais aussi militaire, nécessairement imbriqués. A l'heure du terrorisme, la prolifération des armes nucléaires et des matériaux qui servent à fabriquer des bombes, séquelle de la guerre froide, constitue plus que jamais une menace pour notre survie. Des décisions courageuses de la part des responsables politiques, militaires et industriels s'imposent pour la sécurité internationale et la paix. Un message d'espoir et de raison qui offre à chacun les données nécessaires pour se forger ses propres opinions et participer au débat.

    1986-06-01

    First, R.M.B.K type reactors are described. Then, safety problems are dealt with reactor control, behavior during transients, normal loss of power and behavior of the reactor in case of leak. A possible scenario of the accident of Tchernobyl is proposed: events before the explosion, possible initiators, possible scenario and events subsequent to the core meltdown (corium-concrete interaction, interaction with the groundwater table). An estimation of the source term is proposed first from the installation characteristics and the supposed scenario of the accident, and from the measurements in Europe; radiological consequences are also estimated. Radioactivity measurements (Europe, Scandinavia, Western Europe, France) are given in tables (meteorological maps and fallouts in Europe). Finally, a description of the site is given [fr

    Alisauskas, Sigitas

    2002-01-01

    The corrected triple sum expression of Alisauskas (1987 J. Phys. A: Math. Gen. 20 35) for the recoupling (Racah) coefficients (6j-symbols) of the symmetric (most degenerate) representations of the orthogonal groups SO(n) (previously derived from the fourfold sum expression of Alisauskas also related to the result of Hormess and Junker (1999 J. Phys. A: Math. Gen. 32 4249) is rearranged into three new different double sum expressions (related to the hypergeometric Kampe de Feriet type series) and a new triple sum expression with preferable summation condition. The Regge type symmetry of special 6j-symbols of the orthogonal groups SO(n) in terms of special Kampe de Feriet F 1:4 1:3 series is revealed. The recoupling coefficients for antisymmetric representations of symplectic group Sp(2n) are derived using their relation with the recoupling coefficients of the formal orthogonal group SO(-2n)

  10. The Tchernobyl enigma or: the human factors in severe accidents

    International Nuclear Information System (INIS)

    Llory, M.

    1988-01-01

    Using the analysis of many documents published after the Tchernobyl accident, we attempt to distinguish the main human factors aspects in severe accidents that come out, and the causes the most frequently quoted to ''explain'' it. But the Tchernobyl accident keeps its ''enigmatic'' feature, like any other accident. The need to make a deeper investigation concerning safety leads to look for various research paths that go beyond the usual normative positions, based on a too much mechanistic model of man. It is to the functioning of groups in work situations that we suggest to devote part of the research and thinking effort. We attempt to show briefly how two theories, the theory of ''groupthink'' and the theory of ''trade defensive ideologies'', can throw a light on the problem of human factors in nuclear power plants [fr

  12. A new family of N dimensional superintegrable double singular oscillators and quadratic algebra Q(3) ⨁ so(n) ⨁ so(N-n)

    2015-11-01

    We introduce a new family of N dimensional quantum superintegrable models consisting of double singular oscillators of type (n, N-n). The special cases (2,2) and (4,4) have previously been identified as the duals of 3- and 5-dimensional deformed Kepler-Coulomb systems with u(1) and su(2) monopoles, respectively. The models are multiseparable and their wave functions are obtained in (n, N-n) double-hyperspherical coordinates. We obtain the integrals of motion and construct the finitely generated polynomial algebra that is the direct sum of a quadratic algebra Q(3) involving three generators, so(n), so(N-n) (i.e. Q(3) ⨁ so(n) ⨁ so(N-n)). The structure constants of the quadratic algebra itself involve the Casimir operators of the two Lie algebras so(n) and so(N-n). Moreover, we obtain the finite dimensional unitary representations (unirreps) of the quadratic algebra and present an algebraic derivation of the degenerate energy spectrum of the superintegrable model.

    Laramee, V.; Tannenberg, P. de.

    1996-01-01

    This paper is a brief environmental and socio-economical statement of Bielorussia ten years after the Tchernobyl's Reactor 4 accident. The first part of the paper gives a brief overview of the radiological impact of the accident on land and inhabitants, of the government policy about people evacuation and relocation and of the economical impact of the accident on the agriculture. It summarizes also the financial and administrative advantages given to the people who participated to the emergency operations. The second part of the paper deals with the techniques used in Bielorussia for the exploitation of contaminated lands. Agriculture and farming have started again taking precautionary measures concerning the alimentation of pigs and cattle. About 20000 km 2 of forests are contaminated and could be energetically valorized with the production of electric power or producer gas and partially used in paper industry. However the use of contaminated wood requires the filtering of radioactive aerosols and the processing of ashes for which Bielorussia has not been equipped yet. No satisfactory solution have been proposed so far for the forest litter which is the most contaminated part of the ecosystem. The management of the radioactive wastes generated by the catastrophe is another huge problem recalled in this paper. Most of these wastes were buried in about 800 trenches from which only 200 are known. The remaining could be recovered only with the help of geophysical techniques. (J.S.). 2 refs., 3 photos

    This report relates the Chernobylsk accident, why following a succession of technical malfunctions and human errors, reactor no. 4 of the Chernobylsk nuclear power plant explodes on April 26. 1986. Radioactive dust, aerosols and gases (including caesium and iodine) are ejected into atmosphere. The regions worst hit are in the immediate vicinity of the plant, but deposits are very uneven, producing a leopard spot type of pattern. Propelled by easterly winds, the radioactive cloud disperses increasingly, scattering deposits over the whole of Europe. At the beginning of May, the cloud arrives in France. the eastern portion of the country is most strongly affected. Ground, water and agriculture are contaminated by caesium deposits in Belarus, Ukraine and Russian Federation. About the contamination in France, ground contamination is slight, fourteen years later, however, it is still detectable. Relative to the impact on health in the vicinity of Chernobylsk plant, it is hard to assess this impact. Among children in Southern Belarus, the number of thyroid cancers has risen one hundred-fold. In France, the doses delivered represents generally less than 1% of the average annual dose from radioactivity of natural origin. But some of the doses received were higher. Today, the protective sarcophagus covering the damaged reactor is fragile. Reactor no.3, still in operation, continues to pose a risk but the shutdown is provided for december 2000. (N.C.)

  16. Son, Sent, and Servant

    Truls Åkerlund

    2015-11-01

    Full Text Available This study challenges the claim that Jesus is the archetypical servant leader as described in contempo-rary leadership literature. Based on a theological reading of the Fourth Gospel, the paper suggests that, as a servant, Jesus cannot be understood apart from his mission and obedience to God. Consequently, Jesus was not primarily a servant leader but rather the Son who was sent to the world to enact the Fa-ther’s will. In this regard, the Fourth Gospel provides a unique perspective that is barely noted in the current discourse on servant leadership modelled on the example of Christ. Although certain aspects of servant leadership theory correspond to John’s portrayal of Jesus, the study concludes that other de-scriptions of him as a servant leader suffer from a one-sided and reductionist Christology. Implications of this view for Christian ministry are briefly sketched out.

Probably naturalism allows us to understand how some human actions are possible, but that does not tell us why and how they make sense for everyone. The methodology needed to clarify the first point usually obscures the second one. The best way is to consider that the two approaches do not go together.

  18. ...And Kronos Ate His Sons

    Science.gov (United States)

    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.

Le prétexte du projet est une maquette en plâtre de 70 m2, réalisée par l’architecte Paul Bigot au début du XXe siècle et connue sous le nom de « Plan de Rome ». Le plan de Rome est un objet patrimonial exceptionnel puisqu’il n’a que deux autres équivalents dans le monde : un double conservé à Bruxelles et la maquette réalisée par I. Gismondi, située au Musée de la civilisation romaine de Rome. La restitution virtuelle est entièrement interactive et comprend à la fois de l’architecture et des systèmes mécaniques. En restituant le passé, les chercheurs peuvent tester leurs hypothèses, sous l’aspect architectural et topographique, ou encore tester le fonctionnement des machines. Le visiteur peut se déplacer dans une ville à l’échelle 1, entrer dans la plupart des édifices publics et dans quelques bâtiments privés. Le travail préliminaire à la restitution est celui de l’analyse des sources anciennes, réalisé dans l’équipe, avec l’aide d’experts extérieurs sur des points particuliers. Les sources sont accessibles en permanence depuis le modèle virtuel.Work on developing a virtual model of the city of Rome in the fourth century A.D. began in Caen in 1994.

    Full Text Available La población de la región Huasteca es partícipe de manifestaciones musicales en diferentes ámbitos, lo cual permite reconocer que entre todos los géneros utilizados destaca el son huasteco y su correspondiente bailable llamado huapango. Dichas expresiones musicales se impregnan de los ambientes tanto físico como social que viven constantemente. Es a través de las letras de los sones huastecos que se desarrolla el mecanismo para reflejar el mundo natural que perciben, y los acontecimientos que les suceden, cobrando una importancia que deriva en una identificación que trasciende. Conciben su entorno y lo refieren con sentido de pertenencia-apropiación, que les permite recrear su vida y fundirse en una identificación cultural a la que se le llamará “identidad regional”. La relevancia de considerar una expresión musical de estas características radica en que se preserva y enriquece constantemente unificando un área de México que no necesariamente corresponde a límites políticos establecidos en las diferentes etapas históricas.

  4. Enron: a financial Tchernobyl?

    International Nuclear Information System (INIS)

    Nicolet, J.L.; Alazard, C.; Charron, J.L.

    2004-01-01

    ENRON is almost more striking as an epitome, a model, than as a scandal. It is the perfect illustration of the occurrence of a major financial risk with strong contaminating repercussions. Close examination of the measures taken after this scandal, and the many other scandals (WorldCom, Vivendi etc.) which followed it, indicates that financial risk does not only, as might be imagined on more superficial analysis, take its roots in fraudulent behaviour. On the contrary, fraudulent behaviour appears merely to act as a catalyst. The authors suggest that a global approach integrating the concepts of industrial risk management provides a far more appropriate prism through which to interpret and develop effective controls for financial risks. After recalling the main facts, they apply the concepts of cindynics (the science of danger) to the Enron case and rapidly reach a first major conclusion: the financial system does not have its foundations in any reliable system of measurement.

    This paper reports experimental and modeling results of SON68 glass / magnetite interactions while in contact with synthetic groundwater from a clay environment. It is shown that magnetite enhances glass alteration, first by the sorption of Si released from the glass onto magnetite surfaces, then by a second process that could be the precipitation of an iron silicate mineral or the transformation of magnetite into a more reactive phase like hematite or goethite. This study globally suggests a detrimental effect of magnetite on the long-term durability of nuclear glass in geological disposal conditions. (authors)

    2013-01-01

    Full Text Available 'My Son 22.10.11' was made immediately following a miscarriage 8 weeks into pregnancy. After bleeding lightly for a couple of hours, I went to the toilet and a large bloody mass fell from within me. I knew that I could not flush this away, and that to retrieve the mass was my only chance to connect with the unborn foetus. I fished the contents from the bottom of the toilet bowl using my hands and carried them into my small studio. I found some paper and began to dissect the mass. At the centre, I found the tiny, cold, hard foetus. I kissed it and then began to use it as a kind of painting tool, drawing the outline of the lost child using its very own flesh and blood. I knew that to create a lasting and tangible portrait of 'my son' was the best way to understand the somewhat unreal and fleeting experience of miscarriage. I thought of Frida Kahlo while making the work, thinking 'thank God' that I had a reference to miscarriage before it happened to me. I also thought of my childhood days spent on our family pig farm, and of all the dead pig foetuses that I had seen at various stages of development. Before the miscarriage, I thought little about the subject; afterwards, I recognise the profundity of the creation of a life that is never born. The experience is so common, yet so very rarely discussed or depicted.

  10. Selecting sex: the effect of preferring sons.

    Science.gov (United States)

    Hesketh, Therese

    2011-11-01

    Son preference remains common in countries from East Asia through South Asia to the Middle East and North Africa. Where sex selective technology and abortion are readily available, such as in China, South Korea and India, this has led to a marked excess in male births. Worst excesses are seen in parts of rural China where there are 140 male births for every 100 female. This leads to large numbers of unmarriageable men. Concerns about the consequences centre around the propensity to aggression and violence of these men with increased levels of crime and antisocial behaviour, threatening societal stability and security. But recent studies do not support these assumptions, but rather suggest that these men are marginalised, lonely, withdrawn and prone to psychological problems. Measures to reduce sex selection should include enforcement of existing legislation on sex-selection, and public awareness campaigns about the dangers of late abortion and gender imbalance.

    Full Text Available In this article I review the publishing and stage trajectory of one of Rojas Zorrilla’s most significant plays: Lo que son mujeres. As well as collecting a list of the different editions, I emphasize the 1822 version by the Mexican Manuel Eduardo de Gorostiza, which started a new renaissance period for this play on stage. I also analyze the 1899 one-act version by Emilio Bobadilla. Finally, I include all the different productions between the 17th and the 19th centuries, and address the little interest aroused in the 20th century–suffice to say that it has not been staged even during these early years of the 21st century when the centenary of Rojas Zorrilla is being celebrated.En este artículo se hace un repaso detallado de la fortuna editorial y escénica de una de las obras más significativas de Rojas Zorrilla: Lo que son mujeres. Aparte de recoger las diferentes ediciones de la misma, se hace hincapié en la refundición del mexicano Manuel Eduardo de Gorostiza, estrenada en 1822, que abrió un período de cierta recuperación de este texto dramático en los escenarios. Se analiza también la refundición que llevó a cabo en un solo acto Emilio Bobadilla en 1899. Finalmente, se registran todas las representaciones conocidas de la obra desde el siglo XVII hasta el siglo XIX y se constata el poco interés que ha despertado en los escenarios del siglo XX. Incluso en los últimos años, en los que los montajes de obras de Rojas comienzan a ser más frecuentes, esta obra no ha sido todavía llevada a escena.

CONCLUSIONS: fricatives are acute phonemes comprised between 2500 and 8000 Hz; they are fully acquired up to the age of 3:7 years; the /s/, which is the most affected in cases of short lingual frenum; omission of the /s/ is one of the most frequent occurrences during literacy education; and in the phonological deviation and labial-palatine fissure the entire class of fricatives is frequently affected. In voice assessment, fricative sounds are mentioned as TMF measurements and s/z relationship, and their use as support sounds in speech therapy.

  14. Dombey and Son: An Inverted Maid's Tragedy

    Full Text Available Ross Dabney, J. Butt & K. Tillotson, and others think that Dickens revised the role of Edith in the original plan of Dombey and Son upon the advice of a friend. I tend to believe that Dickens's swerve from his course was prompted by two motives, his relish for grand scenes, and his endeavour to engage the reader's sympathies for a character who was a victim of a social practice which he was trying to condemn. Dickens's humanitarian attitude sought to redeem the sinner and condemn the sin. In engaging the reader's sympathies,  Dickens  had entrapped his own.  Both Edith and Alice are shown as victims of rapacious mothers who sell anything, or anybody for money. While Good Mrs Brown sells Alice's virtue and innocence for cash, Mrs Skewton trades on Edith's beauty in the marriage market to secure fortune and a good establishment. Edith and Alice's maturity and moral growth and their scorn and anger at their mothers' false teaching come in line with public prudery. Moreover, their educators in the principles of Mammonism have not succeeded altogether in stifling their innate feminine tenderness and capacity for affection, the thing that draws them near their reader's heart and wins them love and sympathy.

  15. Mate-sampling costs and sexy sons.

    Science.gov (United States)

    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. © 2014 European Society For Evolutionary Biology.

  17. Coupling coefficients of SO(n) and integrals involving Jacobi and Gegenbauer polynomials

    International Nuclear Information System (INIS)

    Alisauskas, Sigitas

    2002-01-01

    The expressions for the coupling coefficients (3j-symbols) for most degenerate (symmetric) representations of orthogonal groups SO(n) in a canonical basis (with SO(n) restricted to SO(n-1) and different semicanonical or tree bases (with SO(n) restricted to SO(n')xSO(n''), n'+n''=n) are considered, respectively, in context of integrals involving triplets of the Gegenbauer and the Jacobi polynomials. Since the directly derived triple-hypergeometric series do not reveal the apparent triangle conditions of the 3j-symbols, they are rearranged, using their relation with semistretched isofactors of the second kind for the complementary chain Sp(4) contains SU(2)xSU(2) and analogy with the stretched 9j coefficients of SU(2), into formulae with more rich limits for summation intervals and obvious triangle conditions. The isofactors of class-one representations of orthogonal groups or class-two representations of unitary groups (and, of course, the related integrals involving triplets of the Gegenbauer and the Jacobi polynomials) turn into double sums in the cases of canonical SO(n) contains SO(n-1) or U(n) contains U(n-1) and semicanonical SO(n) contains SO(n-2)xSO(2) chains, as well as into the 4 F 3 (1) series under more specific conditions. Some ambiguities of the phase choice of the complementary group approach are adjusted, as well as problems with an alternating sign parameter of SO(2) representations in the SO(3) contains SO(2) and SO(n) contains SO(n-2)xSO(2) chains.

    Urban Indian households with a male first child are approximately 2 percentage points more likely to use clean cooking fuel than comparable households with a female first child. Given Indian son preference, there are at least two mechanisms by which child sex could affect fuel choice: by improving the intrahousehold status of women, who bear more of the costs of traditional fuels, or by presenting an opportunity to invest in children's health, in the context of a preference for healthier boys...

    This article is a survey of the difficult daily life of the people living in a small town 70 km away from Chernobyl. The local authorities have to cope with first, the global aging of the population due to the massive departure of young families in 1991 when the first cases of thyroid cancers broke out and secondly, the arrival of very poor people that settled in the abandoned accommodations. The preventive measures taken to limit the internal contamination of the inhabitants are difficult to implement and maintain because of the invisibility of radioactivity, the flourishing surrounding nature, time passing and the lack of danger awareness of the new inhabitants. The poor standard of population health is due to aging (cancers and cardiovascular diseases), to the impact of radioactive contamination (thyroid cancer among the young) but is aggravated by the very low standard of living (tuberculosis is spreading). The local economy collapsed when 50% of the land were banned from any farming activity because of the radioactive contamination, another important resource was the forest but today a large part of wood is unfit for being sold or used as firewood. On the other hand the management of contaminated areas has driven up the production costs. (A.C.)

    2004-07-01

    ENRON is almost more striking as an epitome, a model, than as a scandal. It is the perfect illustration of the occurrence of a major financial risk with strong contaminating repercussions. Close examination of the measures taken after this scandal, and the many other scandals (WorldCom, Vivendi etc.) which followed it, indicates that financial risk does not only, as might be imagined on more superficial analysis, take its roots in fraudulent behaviour. On the contrary, fraudulent behaviour appears merely to act as a catalyst. The authors suggest that a global approach integrating the concepts of industrial risk management provides a far more appropriate prism through which to interpret and develop effective controls for financial risks. After recalling the main facts, they apply the concepts of cindynics (the science of danger) to the Enron case and rapidly reach a first major conclusion: the financial system does not have its foundations in any reliable system of measurement.

    To analyze desire for sons/daughters among ladies of Peshawar, Pakistan, with a view to rule out son preference and to study impact of various demographic characteristics on the subject. Cross-sectional descriptive study conducted at Combined Military Hospital, Peshawar, from August 2015 - January 2016; sampling technique was random/probability/non-purposive. Self-designed questionnaire was utilized; carrying questions pertinent to desire for sons/daughters during marital life, and demographic details. Data analyzed via descriptive analysis (SPSS-21), expressed as frequencies/percentages and mean ± standard deviation(minimum/maximum). Sons and daughters desired (dependent variables) were cross-tabulated with independent variables. Response rate was 63.25% (n-506). Data revealed following: Sons desired 3.05±2.061(1/12); Daughters desired 1.15±0.767(0/4); 6.1%(n-31) and 0.6%(n-3) desired infinite number of sons and daughters respectively, 18.2%(n-92) did not desire to have even one daughter, while 2.2%(n-11) considered it immaterial to have daughters or sons. There was a significant relation between sons desired and client's education (pGender discrimination can be attenuated by adequately addressing son preference at all tiers.

  4. A test of the "sexy son" hypothesis: sons of polygynous collared flycatchers do not inherit their fathers' mating status.

    Gustafsson, Lars; Qvarnström, Anna

    2006-02-01

    According to the original "sexy son" hypothesis, a female may benefit from pairing with an already-mated male despite a reduction in fecundity because her sons inherit their father's attractiveness. We used data from a long-term study of collared flycatchers (Ficedula albicollis) collected during 24 years to test this prediction. Our results show that the sons of polygynously mated females fledged in poor condition and therefore did not inherit their father's large forehead patch (a condition-dependent display trait) or mating status. From the female's perspective, polygynous pairing resulted in fewer recruited grandchildren than did a monogamous pairing. The reproductive value of sons did not outweigh the fecundity costs of polygyny because the low paternal care reduced the attractiveness of sons. When there are long-lasting parental effects on offspring attractiveness, costs of polygyny may include the production of nonsexy sons.

  6. 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.

  7. Son preference in a rural village in North Vietnam.

    2002-12-01

    This article explores the continuing preference for sons in the context of low fertility in Vietnam. Although the total fertility rate for Vietnam declined from 6.0 children per woman of reproductive age in 1979 to 2.2 children in 1998, demographic evidence shows that son preference remains strong and influences contraceptive and fertility behavior. This study examines the underlying factors for son preference in a rural village in North Vietnam. The methodology includes focus-group discussions, an in-depth study of 25 families, and ethnographic observation. Results indicate that sons are highly desired for their social, symbolic, and economic value. In spite of four decades of socialist policies aimed at reducing gender-based inequalities and at weakening the patriarchal kinship system, the desire for sons continues to drive the family-building process. The article also indicates a gap between discourse and social practice with respect to roles assigned to children on the basis of their sex.

  10. THE MOTIF OF THE PRODIGAL SON IN IVAN TURGENEV'S NOVELS

    Directory of Open Access Journals (Sweden)

    Valentina Ivanovna Gabdullina

    2013-11-01

    Full Text Available The author questions the perception of Ivan Turgenev as a “non- Christian writer” and studies the problem of the prodigal son motif functioning in a series of his novels. In his novels, Turgenev pictured different phases of the archetypal story, originating from the Gospel parable of the prodigal son. In the novel Rudin he depicted the phase of spiritual wanderings of the hero who had lost touch with his native land — Russia. In his next novels (Home of the Gentry, Fathers and Sons and Smoke, after leading his hero in circles and sending him back to his paternal home, Turgenev reconstructs the model of human behavior, represented in the parable, thereby recognizing the immutability of the idea formalized in the Gospel. The motif of the return to Russian land gets its completion in Turgenev's last novel Virgin Soil, in which the author paradoxically connects the Westernist idea with the Gospel imperative. Solomin, the son of a deacon, sent by his wise father out to Europe “to get education”, studies in England, masters the European knowledge and returns back “to his native land” to establish his own business in inland Russia. Thus, a series of Turgenev's novels, in which he portrayed different phases of social life, are interlinked with the motif of the prodigal son, who is represented by novels' main characters.

    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. © The Author(s) 2013 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

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

    Nishino, Hitoshi; Rajpoot, Subhash

    2007-01-01

    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 I ,T J ]=f IJK T K , [T I ,U i ]=-(T I ) ij U j , [U i ,U j ]=-(T I ) ij T I , where T I are the generators of SO(N), while U 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 I ) ij =-(T I ) ji and (T I ) [ij| (T I ) |k]l ≡0. The first nontrivial examples are the spinorial 8 S and conjugate spinorial 8 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) 2 to the new gauge fields for U 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

  18. SO(N) reformulated link invariants from topological strings

    Borhade, Pravina; Ramadevi, P.

    2005-01-01

    Large N duality conjecture between U(N) Chern-Simons gauge theory on S 3 and A-model topological string theory on the resolved conifold was verified at the level of partition function and Wilson loop observables. As a consequence, the conjectured form for the expectation value of the topological operators in A-model string theory led to a reformulation of link invariants in U(N) Chern-Simons theory giving new polynomial invariants whose integer coefficients could be given a topological meaning. We show that the A-model topological operator involving SO(N) holonomy leads to a reformulation of link invariants in SO(N) Chern-Simons theory. Surprisingly, the SO(N) reformulated invariants also has a similar form with integer coefficients. The topological meaning of the integer coefficients needs to be explored from the duality conjecture relating SO(N) Chern-Simons theory to A-model closed string theory on orientifold of the resolved conifold background

    2012-01-01

    SYNOPSIS Objective We address the extent to which parenting practices of fathers and mothers are associated with their sons’ parenting behaviors as young adults and whether adolescent behavior explains this association. Design Data come from 409 young men interviewed in the 2006 Young Adult study of the 1979 National Longitudinal Survey of Youth. Results Men whose fathers were positively involved with them when growing up report more positive parenting of their own children, a direct effect. Less harsh mothering and more positive fathering are associated with reduced adolescent behavior problems, and positive mothering is associated with positive adjustment of these young men as adolescents. However, neither adolescent problem behavior nor positive adjustment is associated with young men’s fathering of their own children, and thus does not explain the association between the fathering young men received and their own fathering behavior. Conclusions Men’s parenting of their sons can have a long-term direct effect on how their sons parent their own children. Although parenting is associated with both positive and negative behaviors of sons during adolescence, these adolescent behaviors are not directly linked to later parenting behavior when sons have their own children. More research is needed to examine mediation mechanisms for the intergenerational transmission of parenting. PMID:23284271

  4. Benefits of Self-Organizing Networks (SON for Mobile Operators

    Directory of Open Access Journals (Sweden)

    Olav Østerbø

    2012-01-01

    Full Text Available Self-Organizing Networks (SON is a collection of functions for automatic configuration, optimization, diagnostisation and healing of cellular networks. It is considered to be a necessity in future mobile networks and operations due to the increased cost pressure. The main drivers are essentially to reduce CAPEX and OPEX, which would otherwise increase dramatically due to increased number of network parameters that has to be monitored and set, the rapidly increasing numbers of base stations in the network and parallel operation of 2G, 3G and Evolved Packet Core (EPC infrastructures. This paper presents evaluations on the use of some of the most important SON components. Mobile networks are getting more complex to configure, optimize and maintain. Many SON functions will give cost savings and performance benefits from the very beginning of a network deployment and these should be prioritized now. But even if many functions are already available and can give large benefits, the field is still in its infancy and more advanced functions are either not yet implemented or have immature implementations. It is therefore necessary to have a strategy for how and when different SON functions should be introduced in mobile networks.

    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. 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. 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. 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.

  11. Sexy sons: a dead end for cytoplasmic genes.

    Critics of sexual conflict theory argue that females may gain a net reproductive benefit from mating with manipulative males because the direct costs that they suffer may be offset by the production of sexy, i.e. manipulative, sons. However, this exclusive focus on nuclear gene effects represents an incomplete view of female fitness. Females differ fundamentally from males in transmitting not only nuclear genes but also a wide range of cytoplasmic genetic elements (CGEs) that can have profound effects, from male killing to influencing development of the nervous system and cognitive ability. Maternal transmission of CGEs has two major implications for sexual selection. First, the evolution of male fitness traits, such as sperm competitive ability, may be constrained because response to selection on mitochondrial genomes can occur only through the female line. Second, CGEs bear the direct costs of male manipulation but gain no indirect benefits when females produce sexy sons. This should result in perpetual antagonistic coevolution between nuclear genes involved in male manipulation and CGEs that promote female resistance to male sexually selected traits. Explicit consideration of the consequences of selection acting on CGEs is therefore necessary for a better understanding of the relationship between sexual selection and sexual conflict.

    Full Text Available Objective: Revealing the experience of mothers when massaging their children to know the phenomenon in the context of a mother-child healthy development. Method: This is a qualitative study with a phenomenological approach carried out with 11 women who massaged their children and answered the guiding question: What did the experience of massaging your child mean to you? Results: The experience of massaging their children meant the development of their being a mother and of being a son/daughter, in addition to developing the attachment relationship between them. The massage can operationalize this integrality, become a tool of communication, stimulation and promotion of secure attachment, by promoting the loving interaction between mother and child. Conclusion: This practice should be considered as an option in the programs that promote the comprehensive health of the mother and child.

    Food shortage is an important selective factor shaping animal life-history trajectories. Yet, despite its role, many aspects of the interaction between parental and offspring food environments remain unclear. In this study, we measured developmental plasticity in response to food availability over two generations and tested the relative contribution of paternal and maternal food availability to the performance of offspring reared under matched and mismatched food environments. We applied a cross-generational split-brood design using the springtail Orchesella cincta, which is found in the litter layer of temperate forests. The results show adverse effects of food limitation on several life-history traits and reproductive performance of both parental sexes. Food conditions of both parents contributed to the offspring phenotypic variation, providing evidence for transgenerational effects of diet. Parental diet influenced sons' age at maturity and daughters' weight at maturity. Specifically, being born to food-restricted parents allowed offspring to alleviate the adverse effects of food limitation, without reducing their performance under well-fed conditions. Thus, parents raised on a poor diet primed their offspring for a more efficient resource use. However, a mismatch between maternal and offspring food environments generated sex-specific adverse effects: female offspring born to well-fed mothers showed a decreased flexibility to deal with low-food conditions. Notably, these maternal effects of food availability were not observed in the sons. Finally, we found that the relationship between age and size at maturity differed between males and females and showed that offspring life-history strategies in O. cincta are primed differently by the parents. © 2016 European Society For Evolutionary Biology.

    Full Text Available Bakunin’s Son, a short novel by Sergio Atzeni, is the perfect embodiment of Bakhtin’s theory of the dialogic novel. The author sets his stories and characters - mostly humble outcast defeated people - in his own homeland, Sardinia. The accurately planned structure as an interview to thirty-two people reflects a multifarious reality with its complex rules and mentality expressed through different points of view, languages and ideologies. The protagonist’s story may result contradictory according to the different opinions of people who met him. Also the choice of a hybrid language contributes to create a highly connoted cultural context. In Bakunin’s Son, in fact, the Italian and the Sardinian overlap in a manner that cannot be distinguished or graphically marked, since form and meaning are fused together.Key words: dialogic novel, hybrid language.O filho de Bakunin, um romance polifónico de Sergio AtzeniO romance breve de Sergio Atzeni, O filho de Bakunin, è a perfeita exemplificação da teoria bachtininana do romance polifónico.

A história è estruturada na forma de entrevista a trinta e duas persona gens que com os seus pontos de vista criam una realidade multi-facetada e subjectiva. A vida de Tullio Saba, o protagonista, está narrada às vezes em modo contraditório e, por isso, os factos podem ser divergentes nas opiniões de quem esteve mais ou menos em contacto directo com ele.

    2002-01-01

    Sons of Gwalia Ltd., in Perth Australia is a long-term supplier of tantalum (Ta), a valuable rare metal with adequate supply. Tantalum is soft and ductile with high melting and boiling points and a low co-efficient of thermal expansion. It has excellent capacity to store and release electrical charge and offers exceptional resistance to corrosion. Its' main use is in consumer electronics such as mobile phones, laptop computers, DVD players, personal video recorders and MP-3 players. For automotive electronics, tantalum is used for air-bags, audio systems, navigation systems, anti-lock break systems and under the hood vehicle management systems. The super alloy is also in demand by the aerospace industry and for turbine blades for power stations. The total demand of Tantalum in 2000 was 5 million lbs. Demand growth has increased steadily since 1993 with perhaps a slight increase in the past 5 years. Resources are estimated at a 125 year supply based on year 2000 production rates. 41 per cent of the world supply of tantalum is obtained from Australia, 13 per cent from Africa, 16 per cent from America, 22 per cent from Asia. The Greenbushes mine in Australia is the world's largest tantalum mine with 80 million lbs Ta, followed by Australia's Wodgina Mine with 50 million lbs Ta. Both mines are expected to be operational for the next 25 years. 12 figs

    State Office for Nuclear Safety has been performed the state supervision over radiation protection at all mammographic centres in the Czech Republic. Inspections are carried out on the basis of requirements of: Act No. 18/1997 Coll., Atomic Act, subsequently amended; Act No. 552/1991 Coll., Supervision Act, subsequently amended; Decree No. 307 /2002 Coll., On radiation protection, as amended by Decree No. 499/2005 Coll. 137 mammography X-ray units have been used actively by 108 independent licensees since 1 September 2008. The mammography screening program started in September 2002. The screening program was carried out at 59 working places last year and already at 66 workplaces with accreditation from 1 up to 3 years this year. The activity of the centres is monitored and inspected continuously (not only by SONS). Inspections at 35 workplaces were carried out last year .The doses are significantly below guidance levels at major part of working places. Most of detected defects were eliminated after inspections. The quality of mammographic workplaces in the Czech Republic has been gradually increased and improved. (authors)

    The goal of the Double Chooz reactor neutrino experiment is to search for the neutrino mixing parameter {theta}{sub 13}. Double Chooz will use two identical detectors at 150 m and 1.05 km distance from the reactor cores. The near detector is used to monitor the reactor {nu}-bar {sub e} flux while the second is dedicated to the search for a deviation from the expected (1/distance){sup 2} behavior. This two detector concept will allow a relative normalization systematic error of ca. 0.6 %. The expected sensitivity for sin{sup 2}2{theta}{sub 13} is then in the range 0.02 - 0.03 after three years of data taking. The antineutrinos will be detected in a liquid scintillator through the capture on protons followed by a gamma cascade, produced by the neutron capture on Gd.

    A geometry of superspace corresponding to double field theory is developed, with type I I supergravity in D=10 as the main example. The formalism is based on an orthosymplectic extension OSp(d,d|2s) of the continuous T-duality group. Covariance under generalised super-diffeomorphisms is manifest. Ordinary superspace is obtained as a solution of the orthosymplectic section condition. A systematic study of curved superspace Bianchi identities is performed, and a relation to a double pure spinor superfield cohomology is established. A Ramond-Ramond superfield is constructed as an infinite-dimensional orthosymplectic spinor. Such objects in minimal orbits under the OSp supergroup (“pure spinors”) define super-sections.

  9. Double inflation

    1986-04-01

    The Zel'dovich spectrum of adiabatic density perturbations is a generic prediction of inflation. There is increasing evidence that when the spectrum is normalized by observational data on small scales, there is not enough power on large scales to account for the observed large-scale structure in the Universe. Decoupling the spectrum on large and small scales could solve this problem. As a means of decoupling the large and small scales we propose double inflation (i.e., two episodes of inflation). In this scenario the spectrum on large scales is determined by the first episode of inflation and those on small scales by a second episode of inflation. We present three models for such a scenario. By nearly saturating the large angular-scale cosmic microwave anisotropy bound, we can easily account for the observed large-scale structure. We take the perturbations on small scales to be very large, deltarho/rho approx. = 0.1 to 0.01, which results in the production of primordial black holes (PBHs), early formation of structure, reionization of the Universe, and a rich array of astrophysical events. The Ω-problem is also addressed by our scenario. Allowing the density perturbations produced by the second episode of inflation to be large also lessens the fine-tuning required in the scalar potential and makes reheating much easier. We briefly speculate on the possibility that the second episode of inflation proceeds through the nucleation of bubbles, which today manifest themselves as empty bubbles whose surfaces are covered with galaxies. 37 refs., 1 fig

    SON is a key component of the spliceosomal complex and a critical mediator of constitutive and alternative splicing. Additionally, SON has been shown to influence cell-cycle progression, genomic integrity, and maintenance of pluripotency in stem cell populations. The clear functional relevance of SON in coordinating essential cellular processes and its presence in diverse human tissues suggests that intact SON might be crucial for normal growth and development. However, the phenotypic effects of deleterious germline variants in SON have not been clearly defined. Herein, we describe seven unrelated individuals with de novo variants in SON and propose that deleterious variants in SON are associated with a severe multisystem disorder characterized by developmental delay, persistent feeding difficulties, and congenital malformations, including brain anomalies.

    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. 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 examine the relationships between parents' and sons' HPV vaccine beliefs and their willingness to have the son receive the vaccine. Less 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 pCommunication campaigns may be able to target these beliefs to increase parents' and sons' willingness to seek HPV vaccination.

  13. Son Preference and Family Limitation in Pakistan: A Parity- and Contraceptive Method-Specific Analysis.

    2017-09-01

    Son preference exerts a strong influence over contraceptive and fertility decisions in many South Asian countries. In Pakistan, where fertility remains high and contraceptive use low, research on son preference has been limited. Data from Pakistan Demographic and Health Surveys conducted in 1990-1991, 2006-2007 and 2012-2013 were used to examine potential indicators and outcomes of son preference. Descriptive analyses looked at sex composition preferences of men and women, as well as the sex ratio at last birth. Multivariate logistic regression analyses examined parity progression by birth order, while multinomial logistic regression was used to identify associations between sex composition and use of permanent, temporary and traditional contraceptive methods. Parity progression and choice of contraceptive method are increasingly associated with the sex composition of children. Many respondents wanted at least two sons, though most also wanted at least one daughter. Analyses suggest that the prevalence of modern contraceptive use among parous women would have been 19% higher in 2012-2013 in the absence of son preference. Permanent method use was extremely low among women with no sons and increased significantly with number of sons. The association between number of sons and use of temporary methods was weaker, while son preference had little relationship with traditional method use. The association of son preference with parity progression and modern contraceptive use has become stronger in Pakistan. Continuation of the fertility transition may be difficult unless the degrees of differential stopping behavior and differential contraceptive use decline.

    Double parton scattering in proton-proton collisions includes kinematic regions in which two partons inside a proton originate from the perturbative splitting of a single parton. This leads to a double counting problem between single and double hard scattering. We present a solution to this problem, which allows for the definition of double parton distributions as operator matrix elements in a proton, and which can be used at higher orders in perturbation theory. We show how the evaluation of double hard scattering in this framework can provide a rough estimate for the size of the higher-order contributions to single hard scattering that are affected by double counting. In a numeric study, we identify situations in which these higher-order contributions must be explicitly calculated and included if one wants to attain an accuracy at which double hard scattering becomes relevant, and other situations where such contributions may be neglected.

    Maternal overweight and obesity in pregnancy has been associated with earlier age of menarche in daughters as well as reduced semen quality in sons. We aimed at investigating pubertal development in sons born by mothers with a high body mass index (BMI). The study included 2522 sons of mothers...... indicators of pubertal development, results also indicated earlier pubertal development among sons of obese mothers. After excluding sons of underweight mothers in a subanalysis, we observed an inverse trend between maternal pre-pregnancy BMI and age at regular shaving, acne and first nocturnal emission....... In conclusion, maternal pre-pregnant obesity may be related to earlier timing of pubertal milestones among sons. More research, preferably based on prospectively collected information about pubertal development, is needed to draw firm conclusions....

  17. In the Pursuit of Sons: Additional Births or Sex-Selective Abortion in Pakistan?

    2016-12-01

    Even though Pakistan is a highly patriarchal society, it has not featured prominently in studies focusing on sex-selective abortion and sex ratios at birth. But with fertility declining and existing strong son preference-Pakistan has one of the highest desired sex ratios in the world-how will Pakistani families respond? In the pursuit of sons, will they have additional children or resort to sex-selective abortions? Or is there evidence that the pursuit of sons is weakening? Using data from three rounds of the demographic and health survey, we show clear evidence of son preference in fertility intentions, patterns of contraceptive use and parity progression ratios. More specifically, we find pervasive evidence that Pakistanis continue childbearing to have a son, to have more than one son and to have at least one daughter. We do not find consistent and convincing evidence that sex ratios at birth (which indicate sex-selective abortion) are increasing.

The study shows that Jesus' use of the expression "son of man" should be understood in the context of the "little tradition" which was reinterpreted in terms of the "great tradition" in a titular way. It is argued that this transition from "litle tradition" to "great t...

    African-American males ages 13 through 24 are disproportionately affected by sexually transmitted infections (STIs) and human immunodeficiency virus (HIV), accounting for over half of all HIV infections in this age group in the United States. Clear communication between African-American parents and their youth about sexual health is associated with higher rates of sexual abstinence, condom use, and intent to delay initiation of sexual intercourse. However, little is known about African-American fathers' perceptions of what facilitates and inhibits sexual health communication with their preadolescent and adolescent sons. We conducted focus groups with 29 African-American fathers of sons ages 10-15 to explore perceived facilitators and barriers for father-son communication about sexual health. Participants were recruited from barbershops in metropolitan and rural North Carolina communities highly affected by STIs and HIV, and data were analyzed using content analysis. Three factors facilitated father-son communication: (a) fathers' acceptance of their roles and responsibilities; (b) a positive father-son relationship; and (c) fathers' ability to speak directly to their sons about sex. We also identified three barriers: (a) fathers' difficulty in initiating sexual health discussions with their sons; (b) sons' developmental readiness for sexual health information; and (c) fathers' lack of experience in talking with their own fathers about sex. These findings have implications for father-focused prevention interventions aimed at reducing risky sexual behaviors in adolescent African-American males. © 2017 Wiley Periodicals, Inc. © 2017 Wiley Periodicals, Inc.

    To examine whether older parents in China would benefit more from daughters' care than from sons' emotional care. Analysis of the unique data sets of the Chinese Longitudinal Healthy Longevity Survey conducted in 2002, 2005, and 2008-2009 in 22 provinces. As compared with having son(s), having daughter(s) is significantly more beneficial at older ages in China, with regard to maintaining higher cognitive capacity and reducing mortality risk. Such daughter advantages in providing emotional care to older parents are more profound among the oldest-old aged 80+ as compared with the young-old aged 65 to 79 and surprisingly more profound in rural areas as compared with urban areas, even though son preference is much more common among rural residents. We describe how educational campaigns aimed at informing the public about the benefits of daughter(s) for older parents' health outcome could help promote gender equality and reduce traditional son preference, especially in rural China.

    2016-02-01

    Research on communication between resident and nonresident African American fathers and their sons about sex has been understudied. The purpose of this study is to determine the influence of parenting variables, specifically, racial socialization and father involvement on nonresident African American father-son communication about sex. Data for this study are from the Fathers and Sons Project. This intervention study is designed to enhance relationships between nonresident African American fathers and their 8-12 year old sons and to prevent risky health behaviors among sons. The present study is based on 345 African American boys who completed baseline face-to-face interviews. The average age of the sons was 10.2 years old (SD = 1.4), with an average of two siblings (SD = 1.53). Age and sons' perceptions of more parental monitoring by their fathers were predictive of increased communication about sex. Racial socialization messages explained additional variance in communication about sex above other parenting variables and controls. Findings suggest when working with African American families, providers who counsel parents, and in particular provide outreach to fathers regarding communication about sex, are in a unique position to enhance parenting communication skills about sexuality. ©2015 American Association of Nurse Practitioners.

  7. Polyandrous females provide sons with more competitive sperm: Support for the sexy-sperm hypothesis in the rattlebox moth (Utetheisa ornatrix).

    Given the costs of multiple mating, why has female polyandry evolved? Utetheisa ornatrix moths are well suited for studying multiple mating in females because females are highly polyandrous over their life span, with each male mate transferring a substantial spermatophore with both genetic and nongenetic material. The accumulation of resources might explain the prevalence of polyandry in this species, but another, not mutually exclusive, possibility is that females mate multiply to increase the probability that their sons will inherit more-competitive sperm. This latter "sexy-sperm" hypothesis posits that female multiple mating and male sperm competitiveness coevolve via a Fisherian runaway process. We tested the sexy-sperm hypothesis by using competitive double matings to compare the sperm competition success of sons of polyandrous versus monandrous females. In accordance with sexy-sperm theory, we found that in 511 offspring across 17 families, the male whose polyandrous mother mated once with each of three different males sired significantly more of all total offspring (81%) than did the male whose monandrous mother was mated thrice to a single male. Interestingly, sons of polyandrous mothers had a significantly biased sex ratio of their brood toward sons, also in support of the hypothesis. © 2015 The Author(s).

    We carried out a comparison of the signals seen in contemporaneous BiSON and GOLF data sets. Both instruments perform Doppler shift velocity measurements in integrated sunlight, although BiSON perform measurements from the two wings of potassium absorption line and GOLF from one wing of the NaD1 line. Discrepancies between the two datasets have been observed. We show,in fact, that the relative power depends on the wing in which GOLF data observes. During the blue wing period, the relative power is mugh higher than in BiSON datasets, while a good agreement has been observed during the red period.

    Full Text Available Abstract Background Licensed for use in males in 2009, Human Papillomavirus (HPV vaccination rates in adolescent males are extremely low. Literature on HPV vaccination focuses on females, adult males, or parents of adolescent males, without including adolescent males or the dynamics of the parent-son interaction that may influence vaccine decision-making. The purpose of this paper is to examine the decision-making process of parent-son dyads when deciding whether or not to get vaccinated against HPV. Methods Twenty-one adolescent males (ages 13–17, with no previous HPV vaccination, and their parents/guardians were recruited from adolescent primary care clinics serving low to middle income families in a large Midwestern city. Dyad members participated in separate semi-structured interviews assessing the relative role of the parent and son in the decision regarding HPV vaccination. Interviews were recorded, transcribed, and coded using inductive content analysis. Results Parents and sons focused on protection as a reason for vaccination; parents felt a need to protect their child, while sons wanted to protect their own health. Parents and sons commonly misinterpreted the information about the vaccine. Sons were concerned about an injection in the penis, while some parents and sons thought the vaccine would protect them against other sexually transmitted infections including Herpes, Gonorrhea, and HIV. Parents and sons recalled that the vaccine prevented genital warts rather than cancer. The vaccine decision-making process was rapid and dynamic, including an initial reaction to the recommendation for HPV vaccine, discussion between parent and son, and the final vaccine decision. Provider input was weighed in instances of initial disagreement. Many boys felt that this was the first health care decision that they had been involved in. Dyads which reported shared decision-making were more likely to openly communicate about sexual issues than those

    on occupation and cryptorchidism. METHODS: The cohort consisted of >600 000 boys born in Denmark from 1980-2007 with a parent in employment during pregnancy. These boys were followed for cryptorchidism from 1980-2009 comparing risks among sons of horticultural workers and farmers with sons of parents in other...... occupations. Hazard ratios (HR) and 95% confidence intervals (95% CI) were estimated using Cox regression adjusting for parental age, birth years, parity, and geographical region. RESULTS: Sons of maternal farmers were at increased risk of cryptorchidism (157 cases; HR 1.31, 95% CI 1.12-1.53) compared to boys...... of mothers in other occupations (15 511 cases). Paternal occupation as farmer was unrelated to the risk among sons. Maternal occupation as a horticultural worker was associated with a non-significantly increased risk (72 cases; HR 1.20, 95% CI 0.95-1.52). A similar association was found for paternal...

    The eukaryotic RNA splicing machinery is dedicated to the daunting task of excising intronic sequences on the many nascent RNA transcripts in a cell, and in doing so facilitates proper translation of its transcriptome. Notably, emerging evidence suggests that RNA splicing may also play direct roles in maintaining genome stability. Here we report the identification of the RNA/DNA-binding protein SON as a component of spliceosome that plays pleiotropic roles during mitotic progression. We found that SON is essential for cell proliferation, and that its inactivation triggers a MAD2-dependent mitotic delay. Moreover, SON deficiency is accompanied by defective chromosome congression, compromised chromosome segregation and cytokinesis, which in turn contributes to cellular aneuploidy and cell death. In summary, our study uncovers a specific link between SON and mitosis, and highlights the potential of RNA processing as additional regulatory mechanisms that govern cell proliferation and division. © 2010 Landes Bioscience

    2017-08-01

    Despite high rates of HIV in areas of Sub-Saharan Africa and men's role in driving the epidemic, little is known about whether or how sexual risk-both behaviors and beliefs-may be passed down through generations of males. This study examined associations between sexual risk behaviors and sex-related beliefs of adolescent males and those of their male caregivers in Kenya, as well as the potential moderating effects of parenting characteristics and father-son relationship quality. Cross-sectional linear regression analysis was applied to baseline data from a trial of a family- and church-based intervention for families in rural Kenya that followed a stepped-wedge cluster randomized design. Our subsample consisted of 79 male caregiver and son (aged 10-16 years) dyads. Results demonstrated a direct relationship between fathers' and sons' sex-related beliefs that was not moderated by parenting or quality of father-son relationship. Parenting/relationship characteristics did moderate the relationship between fathers' and sons' sexual behavior; if fathers did not engage in high-risk sex and exhibited more positive parenting/higher relationship quality, their sons were less likely to be sexually active. Among fathers having high-risk sex, parenting was unrelated to sons' behavior except at very high levels of positive parenting/relationship quality; at these levels, sons were actually more likely to have had sex. Findings support recommendations to include male caregivers in youth HIV prevention efforts, potentially by targeting fathers' parenting strategies and their individual risk.

  19. The institutionalization of Jesus' charismatic authority: "Son of Man" as case study1

    Directory of Open Access Journals (Sweden)

    Yolanda Dreyer

    2000-12-01

    Full Text Available This article argues that Jesus used the expression "son of man" not in a titular way, but genetically, meaning "humankind". This use of "son of man" developed into a titular usage in which Jesus is identified with "Son of Man". The study shows that Jesus' use of the expression "son of man" should be understood in the context of the "little tradition" which was reinterpreted in terms of the "great tradition" in a titular way. It is argued that this transition from "litle tradition" to "great tradition"can be seen as "false attribution". After Jesus' death when his followers reorganized themselves into a cultic community, they gave Jesus the position "founder of the cult". They did this by making use of honorary titles. The use of the title "Son of Man" for Jesus is interpreted in terms of the social theory of the institutionalization of charismatic authority. The focus is on the title "Son of Man" as it appears in legal sayings or church rules, wisdom sayings and prophetic and apocalyptic sayings.

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

    Full Text Available 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 versus 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 be transforming 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. RESULTS In recent decades, fertility has declined to at least replacement levels. Respondents also perceive changes in the gender system, including less son preference, more equal schooling for sons and daughters, more freedom in marriage and pre-marital 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 unique causal contribution to changes in the gender system.

    For more than a decade it has been realised that electrostatic double layers are likely to occur in space. We briefly discuss the theoretical background of such double layers. Most of the paper is devoted to an account of the observational evidence for double layers in the ionosphere and magnetosphere of the Earth. Several different experiments are reviewed including rocket and satellite measurements and ground based observations. It is concluded that the observational evidence for double layers in space is very strong. The experimental results indicate that double layers with widely different properties may exist in space.

    The original method of interpretation together with its theoretical foundations is developed, making it possible to use location and direction of the double-double (tetrad) effect within the Ln and An series to determine the coordination number (CN) complexes of the f-block elements. The method is applied for potentiometric and radiometric equilibrium studies. It has been pointed and that the decisive factor for the direction of the double-double effect in the case of the Gibbs energy variations is a difference in the CN of the f-element ion between the reaction product complex and that for the reaction substrate the ''regular'' effect for a given tetrad is accompanied by decrease in the CN while the ''reverse'' effect by increase in the CN.

    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. © The Author(s) 2015.

    Human embryonic stem cells (hESCs) harbour the ability to undergo lineage-specific differentiation into clinically relevant cell types. Transcription factors and epigenetic modifiers are known to play important roles in the maintenance of pluripotency of hESCs. However, little is known about regulation of pluripotency through splicing. In this study, we identify the spliceosome-associated factor SON as a factor essential for the maintenance of hESCs. Depletion of SON in hESCs results in the loss of pluripotency and cell death. Using genome-wide RNA profiling, we identified transcripts that are regulated by SON. Importantly, we confirmed that SON regulates the proper splicing of transcripts encoding for pluripotency regulators such as OCT4, PRDM14, E4F1 and MED24. Furthermore, we show that SON is bound to these transcripts in vivo. In summary, we connect a splicing-regulatory network for accurate transcript production to the maintenance of pluripotency and self-renewal of hESCs.

    2018-06-01

    In the current study, we explored associations between parent-child coercion and positive parenting in the toddler period in relation to children's social-behavioral development during the school-age period. The data were drawn from the Pitt Mother & Child Project, a sample of 310 low-income, ethnically diverse boys. Drawing on tenets of both attachment and social learning theory, it was hypothesized that coercive mother-son interaction would lead to reductions in positive maternal parenting in the toddler period, and that both positive parenting and mother-son coercion in the toddler period would contribute to children's conduct problems at school entry and lower social skills and peer rejection in middle childhood. The results were largely confirmed, such that mother-son coercive interaction at 18 months was related to decreases in positive parenting at 24 months. Additionally, mother-son coercive interaction and positive parenting at 24 months were linked to child conduct problems at age 5, which in turn predicted child social skills and peer rejection during middle childhood. In addition to indirect effects through child conduct problems, mother-son coercion continued to be independently related to school-age peer rejection. The findings are discussed with respect to the importance of early coercive interactions in the growth of child social-behavioral development from early to middle childhood.

    This study asks parents who have children with Down syndrome (DS) 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 DS 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 DS have good relationships with their siblings with DS. The overwhelming majority of parents surveyed report that they are happy with their decision to have their child with DS and indicate that their sons and daughters are great sources of love and pride.

    Double stars have been systematically observed since William Herschel initiated his program in 1779. In 1803 he reported that, to his surprise, many of the systems he had been observing for a quarter century were gravitationally bound binary stars. In 1830 the first binary orbital solution was obtained, leading eventually to the determination of stellar masses. Double star observations have been a prolific field, with observations and discoveries - often made by students and amateurs - routinely published in a number of specialized journals such as the Journal of Double Star Observations. All published double star observations from Herschel's to the present have been incorporated in the Washington Double Star Catalog. In addition to reviewing the history of visual double stars, we discuss four observational technologies and illustrate these with our own observational results from both California and Hawaii on telescopes ranging from small SCTs to the 2-meter Faulkes Telescope North on Haleakala. Two of these technologies are visual observations aimed primarily at published "hands-on" student science education, and CCD observations of both bright and very faint doubles. The other two are recent technologies that have launched a double star renaissance. These are lucky imaging and speckle interferometry, both of which can use electron-multiplying CCD cameras to allow short (30 ms or less) exposures that are read out at high speed with very low noise. Analysis of thousands of high speed exposures allows normal seeing limitations to be overcome so very close doubles can be accurately measured.

  10. Formation of double layers

    Experiments on both stationary and propagating double layers and a related analytical model are described. Stationary double layers were produced in a multiple plasma device, in which an electron drift current was present. An investigation of the plasma parameters for the stable double layer condition is described. The particle distribution in the stable double layer establishes a potential profile, which creates electron and ion beams that excite plasma instabilities. The measured characteristics of the instabilities are consistent with the existence of the double layer. Propagating double layers are formed when the initial electron drift current is large. Ths slopes of the transition region increase as they propagate. A physical model for the formation of a double layer in the experimental device is described. This model explains the formation of the low potential region on the basis of the space charge. This space charge is created by the electron drift current. The model also accounts for the role of ions in double layer formation and explains the formation of moving double layers. (Auth.)

  11. The relation of son preference and religion to induced abortion: the case of South Korea.

    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.

  15. Mother-son discrepant reporting on parenting practices: The contribution of temperament and depression.

    Shishido, Yuri; Latzman, Robert D

    2017-06-01

    Despite low to moderate convergent correlations, assessment of youth typically relies on multiple informants for information across a range of psychosocial domains including parenting practices. Although parent-youth informant discrepancies have been found to predict adverse youth outcomes, few studies have examined contributing factors to the explanation of informant disagreements on parenting practices. The current study represents the first investigation to concurrently examine the role of mother and son's self-reported affective dimensions of temperament and depression as pathways to informant discrepancies on parenting practices. Within a community sample of 174 mother-son dyads, results suggest that whereas mother's self-reported temperament evidenced no direct effects on discrepancies, the association between the product term of mother's negative and positive temperament and discrepancies on positive parenting was fully mediated by mother's depression (a mediated moderation). In contrast, son's self-reported temperament evidenced both direct and indirect effects, partially mediated by depression, on rating discrepancies for positive parenting. All told, both son's self-reported affective dimensions of temperament and depression contributed to the explanation of discrepant reporting on parenting practices; only mother's self-reported depression, but not temperament, uniquely contributed. Results highlight the importance of considering both parent and youth's report in the investigation of informant discrepancies on parenting practices.

  17. Andrew Wyeth and N.C. Wyeth: a psychodynamic perspective on father and son.

    Science.gov (United States)

    Shaw, Jon A

    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.

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

    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.

    Full Text Available El dolor y el sufrimiento no tienen un referente histórico en el hombre. Solo desde que el hombre es consciente de su humanidad se presenta el dolor y el sufrimiento. El hombre y el dolor siempre han existido, se sufre cuando se nace y se siente dolor, proceso que se repite en cada respiración celular, en cada reacción de oxireducción. Bioló-gicamente en Latín PATIOR = SUFRIR-PADECER es el esfuerzo energético de todo ser vivo para su integración factorial celular.En la medicina el dolor tiene su explicación anatómica y fisiológica, el dolor hace referencia a lo somático y a lo fisiológico. El Dolor agudo es la consecuencia inmediata de la activación del siste-ma nociceptivo, generalmente por un daño tisular somático o visceral, desapareciendo habitualmente con la lesión que lo originó. El Dolor crónico es aquel que persiste en ausencia de la lesión perifé-rica inicial. En la esencia de la filosofía el dolor es impensable e inteligible, se siente, se maneja se tolera pero no se piensa en dolor. Dolor y sufrimiento no son sinónimos pero son intrínsecos a la naturaleza humana. El hombre cuando experimenta el dolor se encuentra con su propio límite, con su propia impotencia de no poder cambiar un hecho real. El sufrimiento humano en la atención diaria del paciente enfermo no lo maneja-mos por ser este algo intangible no monitorizable y mucho menos medible y cuantificable.El dolor del enfermo no es libre ni voluntario, es producto de la fragilidad de su materia, el dolor del que sufre despierta en sus familiares la solidaridad y Tolerancia.

    Full Text Available Double lip, also referred to as "macrocheilia," is a rare anomaly which affects the upper lip more commonly than the lower lip. It consists of a fold of excess or redundant hypertrophic tissue on the mucosal side of the lip. The congenital double lip is believed to be present at birth and becomes more prominent after eruption of teeth. It affects esthetics and also interferes with speech and mastication. Simple surgical excision produces good functional and cosmetic results. We report a case of a non-syndromic congenital maxillary double lip in a 21-year-old male patient.

  7. Why Are Indian Children So Short? The Role of Birth Order and Son Preference.

    2017-09-01

    Child stunting in India exceeds that in poorer regions like sub-Saharan Africa. Data on over 168,000 children show that, relative to Africa, India's height disadvantage increases sharply with birth order. We posit that India’s steep birth order gradient is due to favoritism toward eldest sons, which affects parents' fertility decisions and resource allocation across children. We show that, within India, the gradient is steeper for high-son-preference regions and religions. The gradient also varies with sibling gender as predicted. A back-of-the-envelope calculation suggests that India's steeper birth order gradient can explain over one-half of the India-Africa gap in average child height.

    A qualitative phenomenological study of parents of addicted male adolescents who were residents of a Jewish therapeutic community (TC) describes and interprets the parents' perceptions of the recovery process. Deep, semistructured interviews with 14 parents provided the data. The parents' perceptions were clustered into three main themes of meaning: (a) the process of change, (b) the experiences of family members in the course of the son's recovery process, and (c) the parents' perception of the treatment at Retorno. According to the parents, the admission of their sons into the TC brought notable relief to the family life, which enabled the whole family to begin a recovery process. The findings support the positive criminology perspective that emphasizes the disintegration-integration vector as significant in the recovery process. Recommendations for intervention planning are provided.

  11. The Son's Fault: Martin Luther King, Jr.'s Search for and Recovery of Sonship.

    Science.gov (United States)

    Hinds, Jay-Paul

    2018-04-01

    This article examines the role of sonship in the psychological and spiritual development of men. In using the methodology of psychobiography, I explore the life history of Martin Luther King, Jr. to analyze his search for and recovery of sonship. I propose that sonship helps men rebel against and, in the end, overcome the feelings of inadequacy that are experienced in their struggles to achieve manhood, particularly within the father-son dyad. The scholarship of pastoral theologian Donald Capps is instructive in this regard, in that he suggests that sons should be allowed to search for a male figure, a father-substitute, who can affirm, not disdain or reject, this state of sonship. In the end, what is often viewed as a negative act of regression-i.e., the recovery of and return to sonship-is recognized instead as a positive one that assists a man in his journey toward wholeness.

    2017-01-01

    African American males between ages 13 and 24 are disproportionately affected by unintended pregnancy and sexually transmitted infections (STIs) such as chlamydia, gonorrhea, syphilis, and HIV/AIDS; indeed, they account for 50% of HIV infections among all youth. Clear communication between parents and their youth about sex is associated with higher rates of sexual abstinence, condom use, and intent to delay initiation of sexual intercourse, which can prevent STIs and unintended pregnancy. However, barriers exist for parents to educate their youth about sexual health. The purpose of this article is to explore the values fathers communicate to their sons to prevent their risky sexual behaviors that lead to STIs, HIV, and adolescent parenthood. This was a qualitative study conducted from May and June 2015. African American fathers (N = 29) who had sons, ages 10 to 15 years, participated in five focus groups across metropolitan and rural North Carolina communities in barbershops. A qualitative content analysis revealed four themes regarding areas that fathers imparted their values onto their sons to protect them from sexual health risks: (a) sex, (b) sexuality, (c) relationships, and (d) marriage. The findings have implications for social work and public health practice.

  17. Multivariate Multiple Regression Models for a Big Data-Empowered SON Framework in Mobile Wireless Networks

    Directory of Open Access Journals (Sweden)

    Yoonsu Shin

    2016-01-01

    Full Text Available In the 5G era, the operational cost of mobile wireless networks will significantly increase. Further, massive network capacity and zero latency will be needed because everything will be connected to mobile networks. Thus, self-organizing networks (SON are needed, which expedite automatic operation of mobile wireless networks, but have challenges to satisfy the 5G requirements. Therefore, researchers have proposed a framework to empower SON using big data. The recent framework of a big data-empowered SON analyzes the relationship between key performance indicators (KPIs and related network parameters (NPs using machine-learning tools, and it develops regression models using a Gaussian process with those parameters. The problem, however, is that the methods of finding the NPs related to the KPIs differ individually. Moreover, the Gaussian process regression model cannot determine the relationship between a KPI and its various related NPs. In this paper, to solve these problems, we proposed multivariate multiple regression models to determine the relationship between various KPIs and NPs. If we assume one KPI and multiple NPs as one set, the proposed models help us process multiple sets at one time. Also, we can find out whether some KPIs are conflicting or not. We implement the proposed models using MapReduce.

    2015-01-01

    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.

    2015-01-01

    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. © The Author(s) 2014.

    Based on the recommendations of the sub-workgroup on trauma and dissociative disorders, the American Psychiatric Association (APA) removed the "bereavement exclusion" from the criteria for major depression in DSM-5. In addition, proposed DSM-5 research criteria for persistent complex bereavement disorder (PCBD) were included in the new manual in a section for conditions and criteria needing further research. We describe a case that warranted such a diagnosis. The patient was a 52- year-old woman who was admitted to the inpatient unit of our clinic on the birthday of her son who had died 18 months earlier. She was diagnosed with a manic episode with psychotic symptoms according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision (DSM-IV-TR) criteria and was treated accordingly. Three months after discharge, she made a suicide attempt and was admitted and re-assessed. During this admission, she completed the Inventory of Complicated Grief (ICG), the Mood-Spectrum Rating Scale (MOODS-SR), and the Trauma and Loss Spectrum questionnaire (TALS-SR). She endorsed symptoms of intense yearning for her son, feelings of shock and disbelief, anger and bitterness related to his death, estrangement from others, auditory, tactile and visual hallucinations of the deceased, and intense emotional reactivity to memories of her son. These symptoms were sufficiently prolonged and severe to meet criteria for complicated grief. While complicated grief appeared to be the primary diagnosis for this patient, when she was diagnosed using only DSMIV-TR criteria, her treatment failed to address herprimary problem. This case draws attention to the occurrence of manic-like symptoms as well as depression-like manifestations following bereavement and highlights the importance of including the syndrome of complicated grief in the diagnostic nomenclature.

    Androgens are crucial for normal testicular descent. Studies show that some pesticides have estrogenic or antiandrogenic effects, and that female workers exposed to pesticides have increased risk of having a boy with cryptorchidism. The main objective of the present study was to investigate whether pregnant women exposed to pesticides due to their work in horticulture experience excess risk of having sons with cryptorchidism. We conducted a cohort study of pregnant women working in horticulture using four cohorts including one cohort established with data from the departments of occupational medicine in Jutland and Funen and three existing mother-child cohorts (n=1,468). A reference group was established from the entire Danish population of boys born in the period of 1986-2007 (n=783,817). Nationwide Danish health registers provided information on birth outcome, cryptorchidism diagnosis and orchiopexy. The level of occupational exposure to pesticides was assessed by expert judgment blinded towards outcome status. Risk of cryptorchidism among exposed horticulture workers compared to the background population and to unexposed horticulture workers was assessed by Cox regression models. Pesticide exposed women employed in horticulture had a hazard ratio (HR) of having cryptorchid sons of 1.39 (95% CI 0.84; 2.31) and a HR of orchiopexy of 1.34 (0.72; 2.49) compared to the background population. Analysis divided into separate cohorts revealed a significantly increased risk of cryptorchidism in cohort 2: HR 2.58 (1.07;6.20) and increased risk of orchiopexy in cohort 4: HR 2.76 (1.03;7.35), but no significant associations in the other cohorts. Compared to unexposed women working in horticulture, pesticide exposed women had a risk of having sons with cryptorchidism of 1.34 (0.30; 5.96) and of orchiopexy of 1.93 (0.24;15.4). The data are compatible with a slightly increased risk of cryptorchidism in sons of women exposed to pesticides by working in horticulture.

    2014-03-01

    Full Text Available The paper looks at Shakespeare’s historical play Richard III and its fairy tale-like character given by the configuration of the main character as an arch-villain and the presence of motifs and patterns typically associated with the fairy tale genre. More specifically, it considers the mother-son relationship between the Duchess of York and Richard in the light of the motif of monstrous birth. It is not a coincidence that the emergence of such motifs coincides with the historical contexts of the early modern period. Reading Richard III in this key is related to the revisionist approach to chronicle plays.

    Full Text Available Anaptyxis is a sound appearing that is not found in the original structure of the word. There are three types of anaptyxis: prothesis, epenthesis and epithesis. Epithesis is a vowel or consonant appearing at the end of a word which is not found in the original structure of it. Although, there isn’t not so much example, both vowel and consonant reproduction is seen even in the last sound of the word; but the derivative sound isn’t the same, standard in the whole dialects and accents. Nevertheless some derivative sounds have an intense in a specific region, they aren’t seen in the other areas or has rare example. In this study, the epithesis in the loan words in Turkish will be emphasized. Bir kelimede aslında bulunmayan bir sesin sonradan ortaya çıkmasına ses türemesi denir. Ses türemesinin üç çeşidi vardır: ön türeme, iç türeme, son türeme. Son türeme, kelimenin aslında bulunmayan bir ünlü veya ünsüzün kelime sonunda belirmesidir. Örneği fazla olmamakla birlikte son seste de hem ünlü hem de ünsüz türemesi görülür. Ancak türeyen sesler standart olarak bütün lehçe ve ağızlarda ortak değildir. Türeyen bazı sesler belli bir bölge içerisinde yoğunlaşırken, bazı bölgelerde görülmemekte veya sadece birkaç, hatta bir örnekle sınırlı kalabilmektedir. Bu çalışmada Türkçede alıntı kelimelerdeki son türeme örnekleri üzerinde durulacaktır.

    Full Text Available Disappearance is the loss of a sound in structure of the word with some reasons. There are three types of disappearance: apheresis, syncope and apocope. The apocope is disappearance of a vowel or consonant at the end of a word. This situation isn’t standard in whole dialects and accents. Some dropping sounds, have an intense in a spesific region, they aren’t seen in the other areas or have rare examples. This is rather common in the dialects. In this study will be handled the apocope in the loan words with the examples in Turkey Turkish and contemporary Turkish dialects.

    A unique family survey was conducted in Nepal to investigate the economic consequences of having a first-born girl. Women get more children, but we find no causal effect of number of children on economic outcomes. But independently of the number of children there is a positive effect on boys' education of having a first born sister, who presumably takes care of household work so the boys can focus on school. This indicates a stronger son-preference in Nepal than what is found in studies from ...

    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.

    There are some interesting similarities between Aristotle’s ‘mixed actions’ in Book III of the Nicomachean Ethics and the actions often thought to be justifiable with the Doctrine of Double Effect. Here I analyse these similarities by comparing Aristotle’s examples of mixed actions with standard...... cases from the literature on double effect such as, amongst others, strategic bombing, the trolley problem, and craniotomy. I find that, despite some common features such as the dilemmatic structure and the inevitability of a bad effect, Aristotle’s mixed actions do not count as cases justifiable...... through application of the Doctrine of Double Effect because they fail to meet the crucial necessary condition of the Doctrine according to which the bad effect can only be a merely foreseen side- effect and not an intended means....

    2012-01-01

    Structures of Coulomb clusters formed by dust particles in a plasma are studied by numerical simulation. Our study reveals the presence of various types of self-organized structures of a cluster confined in a prolate spheroidal electrostatic potential. The stable configurations depend on a prolateness parameter for the confining potential as well as on the number of dust particles in a cluster. One-dimensional string, two-dimensional zigzag structure and three-dimensional double helical structure are found as a result of the transition controlled by the prolateness parameter. The formation of stable double helical structures resulted from the transition associated with the instability of angular perturbations on double strings. Analytical perturbation study supports the findings of numerical simulations.

  1. A Stylistic Analysis of D.H. Lawrence’s ‘Sons and Lovers’

    2013-05-01

    Full Text Available This paper aims at analyzing D.H. Lawrence’s ‘Sons and Lovers’ using a stylistic approach. Stylistics is a study of the amalgamation of form with content. The stylistic analysis of a novel goes beyond the traditional, intuitive interpretation, because it combines intuition and detailed linguistic analysis of the text. The defining elements of modern language are within the text itself, not prescribed from outside. With modernist texts, usually understanding comes from close study of the language system defined within the text itself. Form, technique and style are considered not as a mere vehicle of the content of the story, but an integral part of the work’s meaning and value. In our analysis of ‘Sons and Lovers’ the resources of language: lexis, syntax, phonology, figurative language, cohesion and coherence, are discussed in relation to the style of discourse in order to explore hidden meanings in the text. The resources of language are shown to be an essential part of the meaning of the novel.

  2. Cinematic narratives of Sonderkommando: Son of saul or narrating the victim, perpetrator, trauma and death

    Daković Nevena

    2016-01-01

    Full Text Available The aim of this paper is to map out - by analysing the film Son of Saul, but also by its comparison with two other films dealing with the topic, Himmelkommando and The Grey Zone, the narrative mechanism that satisfies the complex ethical and aesthetical demands imposed by the theme of Sonderkommando as the particular episode of the Holocaust. The key element of the narrative structure is the construction of the Levi’s “dead and drowned” witness who “resurrected” through the narrative intervention becomes the only reliable and credible narrator of the historical trauma. The prerequisite for his emergence is the narration and representation of the death which makes but also solves the traumatised - understood as multiple, fragmented, opposed - identities of the members of the special squad. Their entangled identity involves the simultaneous presence of a victim, perpetrator, witness and the authentic narrator of the trauma of the death camp. The death of the perpetrator is the condition sina qua non for the emergence of the figure of the victim-witness narrator but also for making of narrative which overcomes the initial trauma of the Holocaust. The detailed analysis of the film Son of Saul confirms and identifies these narratives as the modernist narration of the post-traumatic film.

    Full Text Available DOI:10.17014/ijog.3.2.127-137The Nam Con Son Basin covering an area of circa 110,000 km2 is characterized by complex tectonic settings of the basin which has not fully been understood. Multiple faults allowed favourable migration passageways for hydrocarbons to go in and out of traps. Despite a large amount of newly acquired seismic and well data there is no significant update on the tectonic evolution and history of the basin development. In this study, the vast amount of seismic and well data were integrated and reinterpreted to define the key structural events in the Nam Con Son Basin. The results show that the basin has undergone two extentional phases. The first N - S extensional phase terminated at around 30 M.a. forming E - W trending grabens which are complicated by multiple half grabens filled by Lower Oligocene sediments. These grabens were reactivated during the second NW - SE extension (Middle Miocene, that resulted from the progressive propagation of NE-SW listric fault from the middle part of the grabens to the margins, and the large scale building up of roll-over structure. Further to the SW, the faults of the second extentional phase turn to NNE-SSW and ultimately N - S in the SW edge of the basin. Most of the fault systems were inactive by Upper Miocene except for the N - S fault system which is still active until recent time.

  4. Thermodynamic and structural models compared with the initial dissolution rates of SON glass samples

    1993-01-01

    The experimentally determined initial dissolution rate R 0 of nuclear glass was correlated with thermodynamic parameters and structural parameters. The initial corrosion rates of six ''R7T7'' glass samples measured at 100 deg C in a Soxhlet device were correlated with the glass free hydration energy and the glass formation enthalpy. These correlations were then tested with a group of 26 SON glasses selected for their wide diversity of compositions. The thermodynamic models provided a satisfactory approximation of the initial dissolution rate determined under Soxhlet conditions for SON glass samples that include up to 15 wt% of boron and some alumina. Conversely, these models are inaccurate if the boron concentration exceeds 15 wt% and the glass contains no alumina. Possible correlations between R 0 and structural parameters, such as the boron coordination number and the number of nonbridging oxygen atoms, were also investigated. The authors show that R 0 varies inversely with the number of 4-coordinate boron atoms; conversely, the results do not substantiate published reports of a correlation between R 0 and the number of nonbridging oxygen atoms.

    Full Text Available David Herbert Lawrence portrays a complex husband-wife, mother-son, and man-woman relationship in his novel Sons and Lovers. This article studied the relational motifs of the major character Paul Morel with other characters and the dire upshot resulting from this relation. The study found that Paul strove for happiness through the concerted entertainment of body and soul with his beloved people, but he failed because his mother’s unusual attachment to him negatively impacted on his building up a normal relation with others. Mother’s failure to find happiness in her conjugal life led her to pouring her love into Paul, exploiting him, making him sub-serve her own need and denying him the right to his own independent life. As a result, the son’s relation with other women proved a disastrous failure. The women with whom Paul had relation underwent part of the sufferings somehow or other. Finally, Mother’s death made him hopeless and left his life in nothingness.

    2007-01-01

    The threshold region of the double-photoionization cross section is of particular interest because both ejected electrons move slowly in the Coulomb field of the residual ion. Near threshold both electrons have time to interact with each other and with the residual ion. Also, different theoretical models compete to describe the double-photoionization cross section in the threshold region. We have investigated that cross section for lithium and beryllium and have analyzed our data with respect to the latest results in the Coulomb-dipole theory. We find that our data support the idea of a Coulomb-dipole interaction.

    A new stellarator configuration, the Double-Helix Stellarator (DHS), is introduced. This novel configuration features a double-helix center post as the only helical element of the stellarator coil system. The DHS configuration has many unique characteristics. One of them is the extreme low plasma aspect ratio, A ∼ 1--1.2. Other advantages include a high enclosed volume, appreciable rotational transform, and a possibility of extreme-high-β MHD equilibria. Moreover, the DHS features improved transport characteristics caused by the absence of the magnetic field ripple on the outboard of the torus. Compactness, simplicity and modularity of the coil system add to the DHS advantages for fusion applications

    Mothers use linking object to externalize the complex aspects of their relationship to the loss of their child. We analyzed the linking objects that mothers kept in memory of their sons who disappeared in the 1991-1995 war in Croatia or whose remains were uncovered and identified long time after they had gone missing. The case study of disturbed mourning included 26 mothers of Croatian soldiers from Croatian Osijek-Baranja County who went missing in war or whose remains were recovered and identified long after they had gone missing. The mothers were selected independently by the president of the Association of Families of Missing and Detained Croatian Soldiers and agreed to participate in the study in 2001. They were interviewed in their homes, their testimonies were recorded, and photographs of the linking objects taken. Linking objects were classified according to the Volkan's four-group classification. Out of four Volkan's groups of linking objects, we identified the objects belonging to the first three. Those were 1) objects that had been worn by the deceased (clothes, wrist-watch, ring, or glasses), (6/26); 2) objects that could be viewed in the psychoanalytic sense as an extension of the body of the disappeared or dead person, such as a camera (4/26); and 3) objects with realistic or symbolic resemblance to the deceased, usually a photograph (8/26). None of the examined objects belonged to the fourth Volkan's group (objects at hand when the news of the death came or objects present at the funeral, things that could be considered last-minute objects, ie, related to the moment when the deceased was last seen alive). However, 8/26 objects formed a new hitherto undescribed group. Mothers used such objects to create a memorial shrine to their sons. A photograph of the missing person or person whose remains were identified long after he had gone missing occupied a central place at the shrine, and was surrounded by other symbols of the Catholic iconography (Virgin

    Many industrialized nations are currently experiencing a decline in average secondary sex ratio (SSR) resulting in fewer boys being born relative to girls. While many potential factors may explain the decline in the birth of males relative to females, it seems most studies support the idea that male offspring are produced less often when environmental conditions are poor owing to males being more susceptible to loss in harsh environments. This study investigates the maternal factors that are associated with the sex of offspring in a cohort of the Australian population. It found that greater parental perceptions of wealth were significantly associated with an increase in the number of sons produced. These results suggest that male offspring are born at increased numbers to women with higher available resources, which may reflect the fact that male offspring are more vulnerable in poor environments.

    Signal transmission by insulin involves tyrosine phosphorylation of a major insulin receptor substrate (IRS-1) and exchange of Ras-bound guanosine diphosphate for guanosine triphosphate. Proteins containing Src homology 2 and 3 (SH2 and SH3) domains, such as the p85 regulatory subunit of phosphatidylinositol-3 kinase and growth factor receptor-bound protein 2 (GRB2), bind tyrosine phosphate sites on IRS-1 through their SH2 regions. Such complexes in COS cells were found to contain the heterologously expressed putative guanine nucleotide exchange factor encoded by the Drosophila son of sevenless gene (dSos). Thus, GRB2, p85, or other proteins with SH2-SH3 adapter sequences may link Sos proteins to IRS-1 signaling complexes as part of the mechanism by which insulin activates Ras.

This essay analyzes two media stories and three films that suggest how limited-and therefore misleading-popular representations of the autism family are. Except for one of the films, these representations blame the problem of adult autistic dependency on either monstrous autism or bad mothering. Doing so elides collective social responsibility for autism care and denies the reality that autistic adults continue to have complex dependency needs that families cannot always meet. Narratives that sensationalize youth and adults with autism or scapegoat their maternal caregivers also diminish opportunities for social inclusion and for autistic people to live fully and dependently.

    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.

    The speciation of uranium in SON68 glass specimens doped with 0.75-3.5 wt% uranium and in the gels formed by alteration of the specimens was investigated by X-ray absorption spectroscopy. In the glasses, uranium is present at oxidation state VI and coordination number 6 with the same average distances than those found in a UO 3 type environment. The U-O distances and uranium coordination numbers are identical throughout the uranium concentration range. During glass alteration the uranium remains at oxidation state VI in the gels, but was found in the uranyl form. An increase in the equatorial distances (from 2.20 and 2.32 A in the glass to respectively 2.22 and 2.39 A in the gel) and coordination numbers (to about 7 and 8, respectively) was observed

    Full Text Available 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.

    Periventricular nodular heterotopia is a common malformation of cortical development in which the migration of developing neurons destined for the cerebral cortex is abbreviated. Bilateral periventricular nodular heterotopia is most commonly an X-linked disorder that involves mutations in the filamin A (FLNA) gene, but an autosomal recessive form and sporadic forms have been identified. To our knowledge, autosomal dominant transmission of isolated periventricular nodular heterotopia has not been reported. Periventricular nodular heterotopia has a heterogeneous phenotype, associated commonly with seizure disorder, and more recently with reading deficits and visual-spatial deficits in some patients. We present a father and son with bilateral periventricular nodular heterotopia and similar visual-spatial learning deficits, consistent with nonverbal learning disability.

    In November 2002, the BDA News carried an item, illustrated with a colour reproduction, describing a painting of a Georgian dentist's rooms by Joseph Mallord William Turner (1775-1851), one of the most respected of English artists, which was shortly to come up for auction at Christies' Rooms in London. This work, first exhibited in 1808, was entitled "The unpaid bill, or the dentist reproving his son's prodigality", and had originally been commissioned by the connoisseur Richard Payne Knight (1750-1824). "The examiner", a contemporary London journal, identifies the 'cradle-piece' for the commission as being a Rembrandt which Payne Knight owned, and the journalist Robert Hunt said that Turner had more than come up to the task of showing that a modern could handle light as well as the old master, 'for a picture of colouring and effect, it is ... inestimable'.

    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.

    Dr. Suh Yang Park was born in 1885 as a son of a butcher, which was the lowest class at that time in Korea. However, contact with western missionaries, including Dr. 0. R. Avison, provided him with an understanding of western civilization. After entering Chejungwon Medical School in 1900, Dr. Park learned basic sciences, basic medical sciences like anatomy and physiology, and other Western medical specialties such as internal medicine and surgery. He graduated from medical school in 1908 and received Government Certificate from Home Office, the first in Korea in this field, which granted the right to practice medicine. His certificate number was 4th overall. As both a doctor and a talented musician, Dr. Park actively participated in the social enlightenment movement. He was quite progressive in his time, having surpassed the social limitations as a son of a butcher, as well as actively propagating his knowledge of Western civilization onto others. After graduation, he had served as a professor at the school he graduated from, until he went into exile in Manchuria in 1917 due to the annexation of Korea by Japan in 1910. There, he opened a hospital and provided medical treatment for Koreans. He also established a school for young Koreans, inspiring them with a sense of nationalism. Also, Dr. Park was an active member of various Independence Movement Organizations in Manchuria. Then in 1932, at the time when Japan took control of Manchuria, his school was closed down. As a result, Dr. Park couldn't help but stop his anti-Japanese activities. In 1936, he returned to his homeland and passed away in 1940, just five years before the liberation of Korea from Japanese occupation.

  10. Bidirectional Associations Between Externalizing Behavior Problems and Maladaptive Parenting Within Parent-Son Dyads Across Childhood.

    Coercive parent-child interaction models posit that an escalating cycle of negative, bidirectional interchanges influences the development of boys' externalizing problems and caregivers' maladaptive parenting over time. However, longitudinal studies examining this hypothesis have been unable to rule out the possibility that between-individual factors account for bidirectional associations between child externalizing problems and maladaptive parenting. Using a longitudinal sample of boys (N = 503) repeatedly assessed eight times across 6-month intervals in childhood (in a range between 6 and 13 years), the current study is the first to use novel within-individual change (fixed effects) models to examine whether parents tend to increase their use of maladaptive parenting strategies following an increase in their son's externalizing problems, or vice versa. These bidirectional associations were examined using multiple facets of externalizing problems (i.e., interpersonal callousness, conduct and oppositional defiant problems, hyperactivity/impulsivity) and parenting behaviors (i.e., physical punishment, involvement, parent-child communication). Analyses failed to support the notion that when boys increase their typical level of problem behaviors, their parents show an increase in their typical level of maladaptive parenting across the subsequent 6 month period, and vice versa. Instead, across 6-month intervals, within parent-son dyads, changes in maladaptive parenting and child externalizing problems waxed and waned in concert. Fixed effects models to address the topic of bidirectional relations between parent and child behavior are severely underrepresented. We recommend that other researchers who have found significant bidirectional parent-child associations using rank-order change models reexamine their data to determine whether these findings hold when examining changes within parent-child dyads.

    The development of constrained peptides for inhibition of protein-protein interactions is an emerging strategy in chemical biology and drug discovery. This manuscript introduces a versatile, rapid and reversible approach to constrain peptides in a bioactive helical conformation using BID and RNase S peptides as models. Dibromomaleimide is used to constrain BID and RNase S peptide sequence variants bearing cysteine (Cys) or homocysteine ( h Cys) amino acids spaced at i and i + 4 positions by double substitution. The constraint can be readily removed by displacement of the maleimide using excess thiol. This new constraining methodology results in enhanced α-helical conformation (BID and RNase S peptide) as demonstrated by circular dichroism and molecular dynamics simulations, resistance to proteolysis (BID) as demonstrated by trypsin proteolysis experiments and retained or enhanced potency of inhibition for Bcl-2 family protein-protein interactions (BID), or greater capability to restore the hydrolytic activity of the RNAse S protein (RNase S peptide). Finally, use of a dibromomaleimide functionalized with an alkyne permits further divergent functionalization through alkyne-azide cycloaddition chemistry on the constrained peptide with fluorescein, oligoethylene glycol or biotin groups to facilitate biophysical and cellular analyses. Hence this methodology may extend the scope and accessibility of peptide stapling.

Ainsi, une application a ete developpee pour l'analyse des sons enregistres. Des essais ont ete realises avec differents microphones pour une meilleure qualite des mesures et un a ete choisi pour la suite du projet. De meme, differents tests ont ete realises sur des anodes de laboratoire ainsi que des anodes a l'echelle industrielle afin de mettre en place une methode pour la detection du temps optimal necessaire au formage des anodes. Les travaux au laboratoire de carbone a l'Universite du Quebec a Chicoutimi (UQAC) ont consiste a l'enregistrement de son des anodes fabriquees sur place avec differentes configurations; et a la caracterisation de certaines anodes de l'usine. Les anodes fabriquees au laboratoire sont reparties en deux groupes. Le premier regroupe les anodes pour la validation de notre methode. Ce sont des anodes produites avec des temps de compaction differents. Le laboratoire de carbone a l'UQAC est unique et il est possible de produire des anodes avec les memes proprietes que celles des anodes industrielles. Par consequent, la validation initialement prevue a l'usine a ete effectuee avec les anodes de laboratoire. Le deuxieme groupe a servi a etudier les effets des matieres premieres sur le temps de compaction. Le type de coke et le type de brai ont constitue les differentes variations dans ce deuxieme groupe. Quant aux tests et mesures a l'usine, ils ont ete realises en trois campagnes de mesure. La premiere campagne en juin 2014 a servi a standardiser et a trouver le meilleur positionnement des appareils pour les mesures, a regler le logiciel et a faire les premieres mesures. Une deuxieme campagne en mai 2015 a fait l'objet d'enregistrement de son en classant les anodes selon differents temps de compaction. La troisieme et derniere campagne en decembre 2015 a

    1978-01-01

    A reinforced concrete double wall nuclear containment structure with each wall including an essentially impervious membrane or liner and porous concrete filling the annulus between the two walls is described. The interior of the structure is maintained at subatmospheric pressure, and the annulus between the two walls is maintained at a subatmospheric pressure intermediate between that of the interior and the surrounding atmospheric pressure, during normal operation. In the event of an accident within the containment structure the interior pressure may exceed atmospheric pressure, but leakage from the interior to the annulus between the double walls will not result in the pressure of the annulus exceeding atmospheric pressure so that there is no net outleakage from the containment structure

  15. Double rupture disc experience

    1979-01-01

    Result of these observations, comparisons and evaluations can be summarized in the following list of concerns regarding the use of double rupture discs coupled to the liquid space of a steam generator that is subjected to a large leak sodium water reaction event. Single rupture disc show delayed collapse characteristics in LLTR Series I and double disc assemblies are presumed to be more complex with additional delay before opening to give pressure relief. Delayed failure increases pressures in the IHTS and must be adequately covered by design requirements. With CRBR design, the first disc may fail only partially reducing the loading on the second disc with the result that relief performance may not meet requirements

    2014-01-01

    I analyze the properties of thin shells through which the scalar curvature R is discontinuous in gravity theories with Lagrangian F(R) = R − 2Λ + αR 2 on the bulk. These shells/domain walls are of a new kind because they possess, in addition to the standard energy–momentum tensor, an external energy flux vector, an external scalar pressure/tension and, most exotic of all, another energy–momentum contribution resembling classical dipole distributions on a shell: a double layer. I prove that all these contributions are necessary to make the entire energy–momentum tensor divergence-free. This is the first known occurrence of such a type of double layer in a gravity theory. I present explicit examples in constant-curvature five-dimensional bulks, with a brief study of their properties: new physical behaviors arise. (fast track communications)

    The dynamics of the idealized Laplacian growth (or the Hele-Shaw problem) can be approximated by the Poiselle flow which in appropriate units takes the form of the Darcy law. In this paper we account for the liquid inertia in the Hele-Shaw problem at zero surface tension limit. The Laplace dynamics for the pressure is extended here with one more for the velocity potential for which we call this growth process the Double Laplacian. The application of the conformal mappings technique leads to doubled dynamics for both the conformal map and the complex potential, which is presented in the paper for the radial and the planar growth. We apply the stability analysis and discuss the integrability for the stated problem. (author)

    Motivated by the problem of identifying Majorana mode operators at junctions, we analyze a basic algebraic structure leading to a doubled spectrum. For general (nonlinear) interactions the emergent mode creation operator is highly nonlinear in the original effective mode operators, and therefore also in the underlying electron creation and destruction operators. This phenomenon could open up new possibilities for controlled dynamical manipulation of the modes. We briefly compare and contrast related issues in the Pfaffian quantum Hall state.

Unhealthy maternal lifestyle during pregnancy such as smoking, high prepregnancy body mass index (BMI as well as alcohol and caffeine intake may constitute possible risk factors for cryptorchidism, but results from the few previous studies are conflicting. We aimed to explore the association between maternal lifestyle factors and occurrence of cryptorchidism in sons.Patients and methods: The Danish National Birth Cohort and the Aarhus Birth Cohort provided information on maternal lifestyle from early pregnancy. Data were linked to several Danish health registers, multiple imputation was used to handle missing data and Cox proportional hazards models were used to adjust for potential confounders.Results: In total, 85,923 boys were included, and of them, 2.2% were diagnosed with cryptorchidism. We observed the strongest associations between maternal tobacco smoking and prepregnancy BMI and cryptorchidism. Sons of women who smoked 10–14 cigarettes/day had the highest hazard ratio (HR for cryptorchidism (1.37; 95% CI: 1.06–1.76, and for maternal BMI ≥30 kg/m2, the HR was 1.32 (95% CI: 1.06–1.65.

    Full Text Available The imaginary and sinister concentration-camp chief Otto Friedrich Zur Linde was conceived by Jorge-Luis Borges as an example of misunderstanding philosophy and life, by seeing in them only the power of fight. This conception is compared with a dynamic understanding of philosophy. For Mr. Zur Linde Aristotle and Plato represent this confrontation, and each philosophical debate in history could be considered as a moment in it. But now, in the last fight, the will to power of man has gone beyond all the limits, even of morality. However some modern techniques of appropriation of ancient philosophy are completely opposed to this conception, namely Paul Ricoeur’s theory of fiction and Heidegger’s Sein und Schein,. Ultimately, the close relationship between poetry and philosophy since its origins speak against this thesis. A closer analysis of Nietzsche and Hölderlin will help to enlighten how wrong Zur Linde´s conception is..El siniestro jefe de un campo de concentración Otto Friedrich Zur Linde, concebido por Borges como ejemplo de una interpretación de la filosofía y la vida en la que la lucha es el único motor, es confrontado con una concepción de la filosofía dinámica. Zur Linde mantiene que Aristóteles y Platón son el enfrentamiento filosófico paradigmático. En el último momento del enfrentamiento la voluntad de poder de un nuevo superhombre ha rebasado todos los límites, incluso el de la conciencia. A esto se oponen las técnicas de apropiación filosófica del mundo griego por parte de la modernidad, a saber: el poder de la ficción, el Schein y el Sein así como el nacimiento de la filosofía, tan cercano a la poesía. Bajo este prisma cabe un análisis de Nietzsche y Hölderlin, que reniega de la interpretación de Zur Linde y clarifica que ante todo poetas y filósofos son seres de palabra.

    Previous studies have shown that cardiac microacceleration signals, recorded either cutaneously, or embedded into the tip of an endocardial pacing lead, provide meaningful information to characterize the cardiac mechanical function. This information may be useful to personalize and optimize the cardiac resynchronization therapy, delivered by a biventricular pacemaker, for patients suffering from chronic heart failure (HF). This paper focuses on the improvement of a previously proposed method for the estimation of the systole period from a signal acquired with a cardiac microaccelerometer (SonR sensor, Sorin CRM SAS, France). We propose an optimal algorithm switching approach, to dynamically select the best configuration of the estimation method, as a function of different control variables, such as the signal-to-noise ratio or heart rate. This method was evaluated on a database containing recordings from 31 patients suffering from chronic HF and implanted with a biventricular pacemaker, for which various cardiac pacing configurations were tested. Ultrasound measurements of the systole period were used as a reference and the improved method was compared with the original estimator. A reduction of 11% on the absolute estimation error was obtained for the systole period with the proposed algorithm switching approach.

    Full Text Available The winner of many prestigious prizes (Oscar for the best foreign language film, Grand Prize of the Cannes Film Festival, and the Golden Globe among them, the Hungarian film, Son of Saul – according to most critics – represents the Holocaust trauma in a completely new and intriguing way. The filmmakers have invented a special form in order to tackle the heroic task of showing the unwatchable, representing the unthinkable. In this essay I analyse the representational strategy of the film from a phenomenological point of view, and position it in the theoretical framework of haptic sensuality formulated by Vivian Sobchack and Laura U. Marks, among others. I mainly focus on the use of sound, in particular the role of sound design in the creation of haptic space. With the help of the analysis of the representation and artistic invocation of the different bodily senses in the film, I demonstrate how traditional artistic formal elements (characteristic of highly artistic, even experimental productions are combined with high impact effects often present in popular film forms. I argue that the successful combination of these two factors makes the film an example of artistic immersive cinema.1

    Full Text Available Bat communities of mainland Southeast Asia can be highly diverse. Many are under threat. Despite this, regional faunal composition is not well documented for many areas, including regions of Vietnam.  We assessed the biodiversity of bats in a watershed protection forest in the southeastern Truong Son (Annamite Mountains, southwestern Quang Ngai Province, Vietnam in 2011–2013.  Twenty species of insectivorous bats were documented including a high diversity of Murina species Tube-nosed Bats.  Diversity and abundance indices were compared with that recorded previously in two nature reserves and one national park in Vietnam, and were higher or comparable in several measures despite the lack of a karst substrate for roosts.  Reproduction in the insectivorous bat fauna coincided with the early rainy season.  In the late dry season, pregnant females of several species were observed but volant juveniles were not present, whereas in the early wet season adult females were lactating or post-lactating and volant juveniles of nine species were detected.  We recorded echolocation calls of 14 bat species; for each species, we compared features of calls with those reported previously in other Asian localities.  For some species we found discrepancies in call metrics among studies, perhaps suggesting a greater hidden biodiversity of bats in Southeast Asia.

    The superselection structure of so(N) WZW models is investigated form the point of view of algebraic quantum field theory. At level 1 it turns out that the observable algebras of the WZW theory can be constructed in terms of even CAR algebras. This fact allows to give a formulation of these models close to the DHR framework. Localized endomorphisms are constructed explicitly in terms of Bogoliubov transformations, and the WZW fusion rules are proven using the DHR sector product. At level 2 it is shown that most of the sectors are realized in H NS =H NS x H NS where H NS is the Neveu-Schwarz sector of the level 1 theory. The level 2 charcters are derived and H NS is decomposed completely into tensor products of the sectors of the WZW chiral algebra and irreducible representation spaces of the coset Virasoro algebra. Crucial for this analysis is the DHR decomposition of H NS into sectors of a gauge invariant fermion algebra since the WZW chiral algebra as well as the coset Virasoro algebra are invariant under the gauge group O(2).

    Liquid waste from Nong Son uranium ore processing is treated with concentrated acid, agglomerated, leached, run through ion exchange and then treated with H 2 O 2 to precipitate yellowcake. The liquid radioactive waste has a pH of 1.86 and a high content of radioactive elements, such as: [U] 143.898 ppm and [Th] = 7.967 ppm. In addition, this waste contains many polluted chemical elements with high content, such as arsenic, mercury, aluminum, iron, zinc, magnesium, manganese and nickel. The application of the general method as one stage precipitation or precipitation in coordination with BaCl 2 is not effective. These methods generated a large amount of sludge with poor settling characteristics. The volume of final treated waste was large. This paper introduces the investigation of the treatment of this liquid radioactive waste by the method of two stage of precipitation in association with polyaluminicloride (PAC) and polymer. The impact of factors: pH, neutralizing agents, quantity of PAC and polymer to effect precipitation and improve the settling characteristics during processing was studied. The results showed that the processing of liquid radioactive waste treatment through two stages: first stage at pH = 3 and the second stage at pH = 8.0 with limited PAC and polymer (A 101) resulted in significant reduced volume of the treated waste. The discharged liquid satisfied the requirement of the National Technical Regulation on Industrial Waste Water (QCVN 24:2009). (author)

    Full Text Available Men have long been associated with dominance, strength and confidence and the issue regarding being compliant to the acceptable masculine ideal has always been part of a culture’s social identity. This study focuses on the critical discussion on masculinity studies in the classic fiction of D.H Lawrence.  Drawing on narrative data from his novel Sons and Lovers (1913, the study examines how hegemonic masculinity is conformed by the male protagonist, Walter Morel, in his gendered relationship. More specifically, the analysis focuses on how the male character aligns himself with the hegemonically authoritarian philosophy of ‘tough’ masculinity. The effects of social practices and socio-historical context in which Lawrence wrote these novels are also examined. The study utilises Connell’s theory of hegemonic masculinity to explicate Lawrence’s depiction of dominant masculinity through his character. The findings reveal that Lawrence aligns his male protagonist to the dominant role by sanctioning aggressiveness, autonomy and violence.

    Full Text Available Background: The theory of attachment is important to understand a lot of human behaviour. Styles of attachment could be important predictors in developing dependence on alcoholism. Insecure attachment patterns could be significant risk factors for future alcohol use. Methods: Participants for this study consist of fathers with alcohol dependence syndrome (ADS from treatment centres and fathers from the community with no dependency on alcohol, and their sons (n=200. The Michigan Alcoholism Screening Test (MAST, socioeconomic status scale were administered, and attachment styles were derived by the Attachment Style Questionnaire (ASQ. We hypothesised a prior concept reflecting theoretical predictions for the association between attachment styles and alcohol in both the generations. Results: Statistics on SPSS-16 was used to test our hypotheses. As predicted, fathers with ADS had insecure attachments styles in comparison to the control group. Substance abuse/dependence and treatment participation were at an all-time low for the secure group. Conclusion: The findings from this study identify attachment styles as an influential factor in understanding the divergence between alcohol dependence in treatment seekers. The findings further imply that differential treatment may need to be provided taking into account one’s attachment representation to promote successful recovery. It also highlights the need to develop secure ties in children of alcoholic parents to protect them from use of substances as a coping and a learned mechanism. Limitations of the study and suggestions for further research are highlighted and implications for diagnosis and treatment are discussed.

    The objective of the study was to identify factors associated with human papilloma virus (HPV) vaccine acceptability in parents of adolescent boys. This information is critical to the development of approaches to optimise HPV vaccine uptake among this population group. We performed a systematic search of the literature in addressing factors influencing parental attitudes to and beliefs about HPV vaccine and its acceptability for use. The findings were organised within the framework of the Health Belief Model (HBM) and summarised using a semi quantitative method. Eighteen studies met the inclusion criteria. Parental decisions were predominantly shaped by the perceived benefits of the vaccine; perceived risk of sons contracting the HPV infection, and having recommendations from health care providers. Fear of side effects and uncertainty about vaccine effectiveness, as well as cost and lack of healthcare, were barriers to HPV vaccination. Other factors such as knowledge, family characteristics, parent-child dialogue and egalitarian values appeared to be important when deciding whether to vaccinate boys. HPV vaccine uptake among male adolescents is suboptimal. Future programs need to address the predictors of uptake by educating parents about the boys' high susceptibility to infection, the benefits of vaccination, and reduce concerns regarding perceived barriers. Additionally, uptake may be facilitated by encouraging health care provider endorsement, particularly in countries without government-funded immunisation programs. Copyright © 2016 Elsevier Inc.

    Cardiofaciocutaneous (CFC) syndrome is a rare genetic disorder belonging to the group of RASopathies. It is typically characterized by congenital heart defects, short stature, dysmorphic craniofacial features, intellectual disability, failure to thrive, and ectodermal abnormalities such as hyperkeratosis and sparse, brittle, curly hair. CFC syndrome is caused by dominant mutations in one of the four genes BRAF, MEK1, MEK2, and KRAS. Only three familial cases of CFC syndrome have been reported to date, whereas the vast majorities are sporadic cases due to de novo mutations. We report on a fourth familial case with transmission of CFC syndrome from father to son due to a novel heterozygous sequence change c.376A>G (p.N126D) in exon 3 of MEK2 gene. This observation further documents the possibility of vertical transmission of CFC syndrome, which appears to be associated with rare mutations and relatively mild intellectual disability in affected individual. The hypomorphic effect of specific mutations particularly regarding neurocognitive issues may be related to the variable fertility of affected individuals. © 2014 Wiley Periodicals, Inc.

    The evolution of the short- and medium-range local environment of lanthanum was determined by L-III-edge X-ray absorption spectroscopy (XAS) during leaching of simplified SON68-type glasses. In glass without phosphorus, lanthanum is found in a silicate environment, and its first coordination sphere comprises eight oxygen atoms at a mean distance of 2.51 angstrom. When this glass was leached at a high renewal rate, the lanthanum local environment was significantly modified: it was present at hydroxy-carbonate and silicate sites with a mean La-O distance of 2.56 angstrom, and the second neighbors consisted of La atoms instead of Si for the glass. Conversely, in the gel formed at low renewal rates, lanthanum was found in a silicate environment similar to that of the glass. In phosphorus-doped glass, lanthanum is found in a phosphate environment, although the Si/P atomic ratio is 20:1. Lanthanum is surrounded by seven oxygen atoms at a mean distance of 2.37 angstrom. When phosphorus-doped glass is leached, regardless of the leaching solution flow rate, the short- and medium-range lanthanum local environment remains almost constant; the most significant change is a 0.05 angstrom increase in the La-O distance.

    In Scandinavia, delivery of a first-born son elevates the risk of preterm delivery and intrauterine growth restriction of the next-born infant. External validity of these results remains unclear. We test this hypothesis for preterm delivery and growth restriction using the linked California birth cohort file. We examined the hypothesis separately by race and/or ethnicity. We retrieved data on 2,852,976 births to 1,426,488 mothers with at least two live births. Our within-mother tests applied Cox proportional hazards (preterm delivery, defined as less than 37 weeks gestation) and linear regression models (birth weight for gestational age percentiles). For non-Hispanic whites, Hispanics, Asians, and American Indian and/or Alaska Natives, analyses indicate heightened risk of preterm delivery and growth restriction after a first-born male. The race-specific hazard ratios for preterm delivery range from 1.07 to 1.18. Regression coefficients for birth weight for gestational age percentile range from -0.73 to -1.49. The 95% confidence intervals for all these estimates do not contain the null. By contrast, we could not reject the null for non-Hispanic black mothers. Whereas California findings generally support those from Scandinavia, the null results among non-Hispanic black mothers suggest that we do not detect adverse outcomes after a first-born male in all racial and/or ethnic groups.

  17. Discussing Sensitive Issues through a Partnership Lens: A Conversation with My Teenaged Son

    Directory of Open Access Journals (Sweden)

    Kris Malone Grossman

    2018-02-01

    Full Text Available This article explores parenting and the construction of masculinity through the lens of Partnership. Framed by the author’s conversation with her teenaged son, the paper opens with a definition, exploration, and cultural contextualization of androcracy. Fundamental intersections between the disciplines of the Partnership Model and Women’s Spirituality are then introduced, locating story and storytelling, spirit, and relationship as cornerstones for shifting from the Domination Model to a Partnership Model. Interconnected theories and praxes of feminism, radical feminism, womanism, and the Womanist Idea, as well as the Jewish concept of tikkun olam, are defined and proposed as tools for educating children about the Domination/Control and interlocking systems of oppression we live in, and how to enact Partnership/Respect principles in our relationships. The paper proposes that through sharing and enacting a multiplicity of counter narratives that reflect the tenets of Partnership, parents and care givers not only actively model for children Partnership values, but they also equip children with an explicit understanding of the harmful systems we live in and the means to challenge and shift them. Highlighting a multiplicity of traditions that share the same core values of empathy, compassion, and care for all living beings, the paper concludes with a set of tools for employing foundational precepts of Partnership Parenting, from sharing story to embodying and promoting ways to care for self, community, and the world.

    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. © 2012 The Author(s). Evolution© 2012 The Society for the Study of Evolution.

    This is an annual report, regularly issued by IPSN, that presents the ecological and health consequences of the Chernobyl Nuclear Accident. The present status of the Chernobyl Nuclear Plant, which Ukraine engaged to stop definitively in year 2000, is summarized. The only reactor unit now in operation is Chernobylsk-3 Reactor which poses two safety questions: evolution of cracks in part of the tubing and behaviour of the pressure tubes. Although, some improvements in the RBMK reactor types were introduced, problems remain that make IPSN to stress the requirement of stopping this NPP completely. In the contaminated territories surrounding Chernobyl incidence rate of infant thyroid cancers continues to grow, reaching values 10 to 100 times higher than the natural rate. In France the IPSN analyzed 60,000 records carried out in 17 sites during May 1986 and April 1989. It was estimated that the individual dose received during 60 years (1986-2046) by the inhabitants of the most affected zone (eastern France) is lower than 1.5 mSv, a value lower than 1% of the natural cosmic and telluric radioactivity exposure for the same period. For the persons assumed to live in the most attacked forests (from eastern France) and nourishing daily with venison and mushrooms the highest estimate is 1 mSv a year. Concerning the 'hot spots', identified in mountains by IPSN and CRIIRAD, the doses received by excursionists are around 0.015 mSv. For an average inhabitant of the country the dose piled up in the thyroid due to iodine-131 fallout is estimated to 0.5-2 mSv for an adult and 6.5-16 mSv for an infant. These doses are 100 to 1000 times lower than the ones to which the infants living in the neighbourhood of Chernobyl are exposed to. The contents of the report is displayed in the following six chapters: 1. Chernobyl in some figures; 2. The 'sarcophagus' and the reactors of the Chernobyl NPP; 3. Health consequences of the Chernobyl accident;. 4. The impact of Chernobyl fallout in France; 5. Chernobyl's environment and the management of contaminated territories.; 6. The French-German initiative for Chernobyl.

    First, are some preliminary comments about the official sanitary assessment of the Chernobyl disaster. The second point concerns the liquidators with the hot particles ( very radioactive particles of some microns) knowledge got from autopsies, from the bronchi pulmonary washing made on sick persons. Always about the liquidators the neurological disorders as post radiative encephalopathy. A third point is relative to the hot particles and the populations. The fourth point is devoted to the birth malformations, in Belarus and Ukraine with an incidence in report with the level of soil contamination (Belarus). The fifth point concerns the alteration of the genome (animals and humans), new mutations appear. The sixth point is devoted to the leukemia in Greece, increase of leukemia incidence among the infants in utero irradiated following Chernobylsk accident. The incidence leukemia of babies ( less than one year old) exposed in utero increases with the soil contamination ( 32.2/10{sup 6}/year in low contaminated soils, 71.4/10{sup 6}/year for average contaminated areas and 141.3/10{sup 6}/year for the most contaminated areas). A final point treats the question of the contamination situation in France and if there is a correlation with an increase of thyroid cancers in Corsica, East and South East of France. The lack of registers that inscribe the cancer cases in the different regions does not allow to make comparison between before and after Chernobylsk accident. But a comparison using the British incidence (0.5/10{sup 6}/year) before Chernobylsk ( in agreement with the incidence found in Belarus before Chernobylsk) shows an increase to 1.17/10{sup 6}/year for the Lorraine area and to 2.25/10{sup 6}/year for the South East and Corsica areas.

  5. Were king Stefan the First-Crowned and his son Radoslav co-rulers?

    Full Text Available The Serbian historiography considers the issue of the co-ruling of King Stefan the First-Crowned and his son Radoslav as the one finally resolved. The suggested solution on the co-rule of Stefan and Radoslav may be most succinctly expressed as following: as early as in the year of 1220, due to the frail health of Stefan the First-Crowned and Radoslav's marriage to Anne the Epirus princess, Radoslav was crowned to be the king and positioned to co-rule with his father after the Byzantine model of governing. Nevertheless this point of view has some loose ends. The notion of co-ruling and the very term of 'co-ruler' are quite freely used in the scholarly works. A general consensus on the precise meaning has not been reached yet. At the point where one author perceives a co-rule, the other categorically denies it. Basically the approach equalizing the heir to the throne and the co-ruler is wrong. Although the co-rulers in most cases were the throne heirs, they cannot be called the co-rulers because of the right to inherit the throne, but for the ruling attributes that formally established that right. The conviction of the co-rule of King Stefan and his son Radoslav is founded on the interpretation of the facts coming from the following sources: entitling charters for the monastery of Žiča, produced by Stefan and Radoslav around 1220; some segments from St. Sava's biographies by Domentian and Theodosius describing the circumstances of Stefan's death-bed leaving the throne to Radoslav; the three acts of the town of Kotor from 1221 and 1227 dated by the rule of king Radoslav, the portraits of Stefan and Radoslav next to the entrance to the Church of the Ascension in the monastery of Žiča and in the nartex of the Mileševa monastery church. In the first Žiča charter, Stefan calls Radoslav his heir, while in the second Žiča charter Stefan points out Radoslav as his first-born son blessed by him to be the king of the whole state.

    Full Text Available This paper attempts to explain parental son preferences among historical Muslim population in the Sandžak region, southwestern Serbia. The paper draws upon data collected in the course of anthropological fieldwork studies in the region. The fieldwork was performed among Muslim and Christian families in Serbian rural area of Sandžak, measuring maternal fitness in relation to several variables. The data set comes from 120 women born between 1880-1924, representing so a historical demographic data based on individual and lineage records. These data were complemented with official records from Archive of Novi Pazar, whenever possible. In this Serbian rural area, land is still considered as an abundant resource, useful in establishing a family, livestock or agriculture. In the past, in spite of yearly fluctuations in production, lands and labor constituted a stable source of wealth from generation to generation. In this study, the data include the socio-economic status of each woman, assigned according to her husband’s family economic status: land-ownership vs. landless. This represents differences in resource availability in terms of nutrition, wealth and workload among these women. As the results show, the Muslim families, on average, left more surviving descendants through sons, in contrast with their Christian counterparts. The basic research question, then, is why? Furthermore, what were the impacts of particular behaviors on reproductive and lineage success, under particular social and ecological conditions? In this sample, regarding the Muslim families, the family structure was/is traditional and stratified, characterized by a large disparity in the status of males and females. Patrilineal inheritance, the concentration of wealth and power in males and the social restriction of women all characterize even today this patriarchal family arrangement. This supports the Trivers-Willard hypothesis, especially in terms of sex-biased parental

    Full Text Available Although Shamgar is described as deliverer of Israel in Judg 3:31, all the regular elements in the description of the work of Israel’s judges seems to be lacking there (for example, the official titles שפט or מושיע. In this context the tradition of Josephus (Antiquities 5:197 is instructive here: Σανάγαρος ὁ Ἀνάθου παῖς αἱρεθεὶς ἄρχειν ἐν τῷ πρώτῳ τῆς ἀρχῆς ἔτει κατέστρεψε τὸν βίον (“Sanagaros, the Anath’s son, having been chosen to rule, in the first year of his rule lost his life”. If Josephus’ biblical source was basically the same as the Masoretic Text, he seems to understood the lexeme הבקר of Judg 3:31 as a passive verbal form from the root בקר, in the sense attested in the Qumran scrolls, where the term מבקר means “supervisor, inspector.” Therefore, although the standard formula of assuming the rule is missing there, the consonantal Hebrew text permits one to recognize Shamgar as chief and deliverer of Israelites. He “has been appointed” (הֻבְקַר to be a “supervisor, chief” (compare αἱρεθεὶς ἄρχειν in Josephus of Israel.

    Full Text Available The Double Star Programme (DSP was first proposed by China in March, 1997 at the Fragrant Hill Workshop on Space Science, Beijing, organized by the Chinese Academy of Science. It is the first mission in collaboration between China and ESA. The mission is made of two spacecraft to investigate the magnetospheric global processes and their response to the interplanetary disturbances in conjunction with the Cluster mission. The first spacecraft, TC-1 (Tan Ce means "Explorer", was launched on 29 December 2003, and the second one, TC-2, on 25 July 2004 on board two Chinese Long March 2C rockets. TC-1 was injected in an equatorial orbit of 570x79000 km altitude with a 28° inclination and TC-2 in a polar orbit of 560x38000 km altitude. The orbits have been designed to complement the Cluster mission by maximizing the time when both Cluster and Double Star are in the same scientific regions. The two missions allow simultaneous observations of the Earth magnetosphere from six points in space. To facilitate the comparison of data, half of the Double Star payload is made of spare or duplicates of the Cluster instruments; the other half is made of Chinese instruments. The science operations are coordinated by the Chinese DSP Scientific Operations Centre (DSOC in Beijing and the European Payload Operations Service (EPOS at RAL, UK. The spacecraft and ground segment operations are performed by the DSP Operations and Management Centre (DOMC and DSOC in China, using three ground station, in Beijing, Shanghai and Villafranca.

  19. Firewalls from double purity

    Science.gov (United States)

    Bousso, Raphael

    2013-10-01

    The firewall paradox is often presented as arising from double entanglement, but I argue that more generally the paradox is double purity. Near-horizon modes are purified by the interior, in the infalling vacuum. Hence, they cannot also be pure alone, or in combination with any third system, as demanded by unitarity. This conflict arises independently of the Page time, for entangled and for pure states. It implies that identifications of Hilbert spaces cannot resolve the paradox. Traditional complementarity requires the unitary identification of infalling matter with a scrambled subsystem of the Hawking radiation. Extending this map to the infalling vacuum overdetermines the out-state. More general complementarity maps (“A=RB,” “ER=EPR”) necessarily fail when the near-horizon zone is pure. I argue that pure-zone states span the microcanonical ensemble, and that this suffices to make the horizon a special place. I advocate that the ability to detect the horizon locally, rather than the degree or probability of violence, is what makes firewalls problematic. Conversely, if the production of matter at the horizon can be dynamically understood and shown to be consistent, then firewalls do not constitute a violation of the equivalence principle.

    Full Text Available Utiliser un film, ou toute création culturelle, pour comprendre le social pose un certain nombre de problèmes méthodologiques. Un film n’est pas un « reflet ». Une création, même si elle se place sous le sceau du réalisme, a un rapport très fort mais indirect avec le contexte historique de sa genèse. Elle est le produit de la rencontre d’un contexte, d’un créateur doté d’une idéologie, d’un « habitus », d’un corpus de valeurs, des modes et techniques en vigueur dans le champ de la création au moment de celle-ci et, comme le rappelle Bourdieu, de la stratégie du créateur par rapport à ses collègues/concurrents. Enfin, sans ajouter une note discordante supplémentaire aux théories de la réception, l’œuvre sera perçue de façon différente selon les publics. My Son the Fanatic sera donc perçu comme une œuvre satanique par les fondamentalistes musulmans, mais sans doute aussi chrétiens, comme une bluette charmante par les midinettes au grand cœur qui semblent être le public visé par la présentation publicitaire du film, comme une démonstration de la justesse de leurs thèses par les partisans de l’intégration, mais aussi par les émules de Huntington pour qui le choc des civilisations est inéluctable, enfin comme une manifestation irresponsable d’ « islamophobie » par les nostalgiques des politiques multiculturalistes d’antan. Les aficionados de Hanif Kureishi, auteur de la nouvelle sur laquelle le film est fondé, et scénariste du film lui-même, y retrouveront le plaidoyer pour la liberté individuelle et, en particulier, la liberté sexuelle qu’ils attendent, mais seront un peu surpris par les côtés didactiques, pour employer cet adjectif dans une acception qui déplait aux didacticiens, c'est-à-dire une volonté de démonstration un peu insistante.Using films, or, for that matter, any cultural artefact in order to reach an understanding of social issues raises a number of

    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

    Full Text Available This article is based on research done within the Afrikaansspeaking community in the area of the Drakenstein Municipality, Western Cape province, South Africa. The focus falls specifically on one concept that was outlined during the research, namely the perceptions of fathers and adolescent sons on identity formation within their relationship as well as the role that God plays. Combined qualitative/quantitative research was conducted with emphasis on semi-structured interviews with fathers (n=4 and adolescent boys (n=4 and an auto-ethnography of the author as the dominant component. The lessdominant quantitative component consisted of questionnaires completed by fathers (n=42 and adolescent boys (n=180. Metatheoretical assumptions and theoretical assumptions as grounding for the male identity are discussed as part of the author’s paradigmatic perspective. Furthermore, empirical findings are discussed and recommendations are made. From the discussions with fathers and their sons it was clear that both fathers and sons have a need to stand in close relationship to each other and to God. It is within this relationship where their identities are formed. However, fathers seemed to be resistant of transferring their beliefs to their sons. Adolescent boys also indicated no need to one day transfer learned behaviour from their fathers to their sons.

    Regardless of the formation mechanism, an exotic object, the double degenerate star (DDS), is introduced and investigated, which is composed of baryonic matter and some unknown fermion dark matter. Different from the simple white dwarfs (WDs), there is additional gravitational force provided by the unknown fermion component inside DDSs, which may strongly affect the structure and the stability of such kind of objects. Many possible and strange observational phenomena connecting with them are concisely discussed. Similar to the normal WD, this object can also experience thermonuclear explosion as type Ia supernova explosion when DDS's mass exceeds the maximum mass that can be supported by electron degeneracy pressure. However, since the total mass of baryonic matter can be much lower than that of WD at Chandrasekhar mass limit, the peak luminosity should be much dimmer than what we expect before, which may throw a slight shadow on the standard candle of SN Ia in the research of cosmology.

    Resonant triple-differential cross-section (TDCS) measurements have been used to study the double photoionization process in strontium. Two sets of measurements were made at the photon energy of the 4p {yields} 4d resonance. The coplanar geometry was used and the fixed analyser, positioned at -90{sup 0} to the main axis of polarization of the photons, detected electrons with {approx}65% of the available excess energy. The mutual angle between the two electrons had a range just short of 90 {yields} 270{sup 0}. The TDCS exhibit unexpected lobes at a mutual angle of 180{sup 0}. Comparison with other measurements made with the same geometry but with different sharings of the available energy indicate that these TDCS all show the unexpected lobe. Some possible explanations for the lobe are considered.

    The successful deconvolution of data from double Doppler broadening of annihilation radiation (D-DBAR) spectroscopy is a promising area of endeavour aimed at producing momentum distributions of a quality comparable to those of the angular correlation technique. The deconvolution procedure we test in the present study is the constrained generalized least square method. Trials with computer simulated DDBAR spectra are generated and deconvoluted in order to find the best form of regularizer and the regularization parameter. For these trials the Neumann (reflective) boundary condition is used to give a single matrix operation in Fourier space. Experimental D-DBAR spectra are also subject to the same type of deconvolution after having carried out a background subtraction and using a symmetrize resolution function obtained from an 85 Sr source with wide coincidence windows.

    Double mode pulsation is a very pervasive phenomenon in stars all over the Hertzsprung-Russell diagram. In order of increasing radius, examples are: ZZ Ceti stars, the sun, the delta Scuti stars, RR Lyrae variables, the β Cephei variables and those related to them, Cepheids, and maybe even the Mira stars. These many modes have been interpreted as both radial and nonradial modes, but in many cases the actual mode has not been clearly identified. Yellow giants seem to be the most simple pulsators with a large majority of the RR Lyrae variables and Cepheids showing only one pulsation period. We limit this review to those very few cases for classical Cepheids and RR Lyrae variables which display two modes. For these we know many facts about these stars, but the actual cause of the pulsation in two modes simultaneously remains unknown

    We present the dual formulation of double field theory at the linearized level. This is a classically equivalent theory describing the duals of the dilaton, the Kalb-Ramond field and the graviton in a T-duality or O(D,D) covariant way. In agreement with previous proposals, the resulting theory encodes fields in mixed Young-tableau representations, combining them into an antisymmetric 4-tensor under O(D,D). In contrast to previous proposals, the theory also requires an antisymmetric 2-tensor and a singlet, which are not all pure gauge. The need for these additional fields is analogous to a similar phenomenon for “exotic' dualizations, and we clarify this by comparing with the dualizations of the component fields. We close with some speculative remarks on the significance of these observations for the full non-linear theory yet to be constructed.

    We propose a generalized double Pareto prior for Bayesian shrinkage estimation and inferences in linear models. The prior can be obtained via a scale mixture of Laplace or normal distributions, forming a bridge between the Laplace and Normal-Jeffreys' priors. While it has a spike at zero like the Laplace density, it also has a Student's t -like tail behavior. Bayesian computation is straightforward via a simple Gibbs sampling algorithm. We investigate the properties of the maximum a posteriori estimator, as sparse estimation plays an important role in many problems, reveal connections with some well-established regularization procedures, and show some asymptotic results. The performance of the prior is tested through simulations and an application.

  13. Double optical gating

    Science.gov (United States)

    Gilbertson, Steve

    The observation and control of dynamics in atomic and molecular targets requires the use of laser pulses with duration less than the characteristic timescale of the process which is to be manipulated. For electron dynamics, this time scale is on the order of attoseconds where 1 attosecond = 10 -18 seconds. In order to generate pulses on this time scale, different gating methods have been proposed. The idea is to extract or "gate" a single pulse from an attosecond pulse train and switch off all the other pulses. While previous methods have had some success, they are very difficult to implement and so far very few labs have access to these unique light sources. The purpose of this work is to introduce a new method, called double optical gating (DOG), and to demonstrate its effectiveness at generating high contrast single isolated attosecond pulses from multi-cycle lasers. First, the method is described in detail and is investigated in the spectral domain. The resulting attosecond pulses produced are then temporally characterized through attosecond streaking. A second method of gating, called generalized double optical gating (GDOG), is also introduced. This method allows attosecond pulse generation directly from a carrier-envelope phase un-stabilized laser system for the first time. Next the methods of DOG and GDOG are implemented in attosecond applications like high flux pulses and extreme broadband spectrum generation. Finally, the attosecond pulses themselves are used in experiments. First, an attosecond/femtosecond cross correlation is used for characterization of spatial and temporal properties of femtosecond pulses. Then, an attosecond pump, femtosecond probe experiment is conducted to observe and control electron dynamics in helium for the first time.

    Leber congenital amaurosis (LCA) is most often an autosomal recessive disorder. We report a father and son with autosomal dominant LCA due to a mutation in the CRX gene. DNA screening using an allele specific assay of 90 of the most common LCA-causing variations in the coding sequences of AIPL1, CEP290, CRB1, CRX, GUCY2D, RDH12 and RPE65 was performed on the father. Automated DNA sequencing of his son examining exon 3 of the CRX gene was subsequently performed. Both father and son have a heterozygous single base pair deletion of an adenine at codon 153 in the coding sequence of the CRX gene resulting in a frameshift mutation. Mutations involving the CRX gene may demonstrate an autosomal dominant inheritance pattern for LCA.

  17. Double Charge Exchange Reactions and Double Beta Decay

    Auerbach, N.

    2018-05-01

    The subject of this presentation is at the forefront of nuclear physics, namely double beta decay. In particular one is most interested in the neutrinoless process of double beta decay, when the decay proceeds without the emission of two neutrinos. The observation of such decay would mean that the lepton conservation symmetry is violated and that the neutrinos are of Majorana type, meaning that they are their own anti-particles. The life time of this process has two unknowns, the mass of the neutrino and the nuclear matrix element. Determining the nuclear matrix element and knowing the cross-section well will set limits on the neutrino mass. There is a concentrated effort among the nuclear physics community to calculate this matrix element. Usually these matrix elements are a very small part of the total strength of the transition operators involved in the process. There is no simple way to “calibrate” the nuclear double beta decay matrix element. The double beta decay is a double charge exchange process, therefore it is proposed that double charge exchange reactions using ion projectiles on nuclei that are candidates for double beta decay, will provide additional necessary information about the nuclear matrix elements.

    The high crash rates among teenage drivers are of great concern across nations. Parents' involvement is known to help increase their young drivers' driving safety. In particular, parents can place restrictions on their son's/daughter's driving (e.g., restrict night time driving), which can enable the young driver to gain driving experience in…

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

    Science.gov (United States)

    Hamm, Jay A; Leonhardt, Bethany L; Fogley, Rebecca L; Lysaker, Paul H

    2014-12-01

    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.

    Full Text Available A composição na minha trajetória representa uma síntese de experiências diversas. Foi juntando extremidades opostas, a teoria musical e a pesquisa de um lado, a improvisação como pianista do outro, que a vontade de reunir reflexão e prática encontrou na composição a sua forma de expressão. Minha formação se deu inicialmente em um curso de inverno no Festival de Londrina com Hans J. Koellreutter em 1994. Em seguida, tive uma longa passagem pela universidade (bacharelado em composição na Unicamp, mestrado na mesma universidade. A pesquisa de doutorado sobre Luigi Nono (USP me ajudou a entrar em contato com a forma de abordagem intuitiva e baseada no som do compositor italiano, que também seria tão importante no meu trabalho. Sobre meus professores, numerosos diálogos me foram necessários - toda uma constelação de eventos para uma única págica de música bem-sucedida. Entre esses encontros, que tiveram um papel pedagógico fundamental - muito embora alguns deles tenham sido breves em forma de workshop ou conversa, estão as aulas de J. A. Mannis, Almeida Prado, Livio Tragtenberg, Fernando Iazzetta, Silvio Ferraz, Salvatore Sciarrino, Chaya Czernowin, Pierluigi Billone, Franck Bedrossian, Tristan Murail, Stefano Gervasoni, Michael Jarrell e Philippe Manoury. Minha experiência com o grupo de improvisação Abaetetuba, e em duo com Celio Barros e Florentin Ginot, constituiu meu grande laboratório prático, desenvolvendo escuta e resposta em forma de sons, que considero como uma importante etapa de gestação do meu projeto artístico.

  9. Double Tracks closure report

    International Nuclear Information System (INIS)

    1997-06-01

    This report describes the remediation activities performed and the results of postremediation radiation surveys conducted at the Double Tracks site, located on Range 71 North, of the Nellis Air Force Range (NAFR) in southern Nevada. This remediation was conducted from June to August 1996 in accordance with the Interim Corrective Action Plan (ICAP) to remediate the site to an acceptable risk to human health and the environment. Soil with a total transuranic activity greater than 200 picoCuries per gram (pCi/g) was excavated, shipped to the Nevada Test Site (NTS), and disposed at the Area 3 Radioactive Waste Management Site (RWMS). A total of 52.3 grams of plutonium (Pu) with an activity of 5.12 Curies was disposed. The concrete pad at ground zero (GZ) was broken up, placed in a Sealand reg-sign container, and shipped to the NTS Area 6 decontamination pad. Additionally, approximately 10 m 3 (350 ft 3 ) of soil containing small chips of concrete was shipped to the NTS Area 6 decontamination pad. The concrete and soil/concrete mixture will be further characterized prior to disposal. At the time this report was written, characterization samples were being collected, with analytical results expected in January 1997. It is anticipated that the material will be disposed in mid-1997. This remediation is an interim action because final cleanup levels have not been established

  10. Double Beta Decay

    International Nuclear Information System (INIS)

    Fiorini, Ettore

    2008-01-01

    The importance of neutrinoless Double Beta Decay (DBD) is stressed in view of the recent results of experiments on neutrino oscillations which indicate that the difference between the squared masses of two neutrinos of different flavours is finite [For a recent review including neutrino properties and recent results see: Review of Particle Physics, J. of Phys. G: Nuclear and Particle Physics 33, 1]. As a consequence the mass of at least one neutrino has to be different from zero and it becomes imperative to determine its absolute value. The various experimental techniques to search for DBD are discussed together with the difficult problems of the evaluation of the corresponding nuclear matrix elements. The upper limits on neutrino mass coming from the results of the various experiments are reported together with the indication for a non zero value by one of them not confirmed so far. The two presently running experiments on neutrinoless DBD are briefly described together with the already approved or designed second generation searches aiming to reach the values on the absolute neutrino mass indicated by the results on neutrino oscillations

  11. Analyzing Double Image Illusion through Double Indiscernibility and Lattice Theory

    2011-10-01

    Full Text Available The figure-ground division plays a fundamental role in all image perceptions. Although there are a lot of studies about extraction of a figure such as detection of edges or grouping of texture, there are few discussions about a relationship between obtained figure and ground. We focused on double image illusions having two complementary relationships be- tween figure and ground and analyzed them. We divided the double image illusions according to two different interpretations and using these divisions we extracted and analyzed their logical structures by lattices derived from rough sets that we had developed. As a result we discovered unusual logical structures in double image illusions.

  12. The sexual double standard in African American adolescent women's sexual risk reduction socialization.

    Fasula, Amy M; Miller, Kim S; Wiener, Jeffrey

    2007-01-01

    This study explored the sexual double standard (SDS) (in which males are afforded more freedom and power than females in heterosexual interactions) in African American mothers' sexual messages to sons and daughters. We used a convenience sample of 129 African American adolescents, aged 14 to 17 years, and their mothers who reported SDS attitudes. Qualitative analyses revealed gender differences based on an SDS in mothers' sexual risk reduction socialization. Mothers typically took a proactive approach with sons and a neutral or prohibitive approach with daughters. Findings provide directions for socially relevant programs for African American parents, schools, and communities.

    2000-07-01

    This study is a contribution in the understanding of the long time behavior of alteration products of the glass SON 68, used to simulate the nuclear glass R7T7. The local structure around Zirconium and iron has been probed using X-ray absorption spectroscopy in altered surface layer of glass SON 68. Alteration products of this glass have been prepared for short (3 hours to 7 days) and long (17 months) time, using various indexes of saturation for the leaching solution with respect to the Si content of the glass (from 0 to 90 %). The evolution of the local structure around Fe has also been studied in recent and old natural ferric gels. Zr, Fe- L{sub 2,3} XANES and Zr, Fe-K EXAFS spectroscopies have shown that, in the pristine glass, these elements are connected to the polymeric network. Zr is found in an environment close to that of a zircon-silicate containing Na and Ca. Trivalent Fe is a network former. The leached layer of glass SON 68 is constituted of poorly ordered Zr-and Fe-(oxi-hydr)oxides that may have been formed by a mechanism of dissolution/precipitation; a relict phase with the same Zr local structure as that observed in the pristine glass, probably obtained thanks to in-situ solid condensation. The structural characteristics of the leached layer are observed from the first steps of alteration for Zr and Fe. Conversely to Fe, the structural status of Zr depends on the leaching kinetic as well as the contents of Ca and Si in the solid. Fe-K EXAFS results in recent natural ferri-hydrides present a clear structural similarity with that determined in glass SON 68 leached products. The study of old paleosols (between 1,800 and 200,000 years) has demonstrated the long time stability of ferric gels, although an increase of medium range order around Fe is seen. (author)

    2014-01-01

    A binary linear code C is a Z2-double cyclic code if the set of coordinates can be partitioned into two subsets such that any cyclic shift of the coordinates of both subsets leaves invariant the code. These codes can be identified as submodules of the Z2[x]-module Z2[x]/(x^r − 1) × Z2[x]/(x^s − 1). We determine the structure of Z2-double cyclic codes giving the generator polynomials of these codes. The related polynomial representation of Z2-double cyclic codes and its duals, and the relation...

    We clarify the relation between various approaches to the manifestly T-duality symmetric string. We explain in detail how the PST covariant doubled string arises from an unusual gauge fixing. We pay careful attention to the role of “spectator” fields in this process and also show how the T-duality invariant doubled dilaton emerges naturally. We extend these ideas to non-Abelian T-duality and show they give rise to the duality invariant formalism based on the semi-Abelian Drinfeld Double. We then develop the N=(0,1) supersymmetric duality invariant formalism.

    2013-03-01

    Full Text Available The article intends to address the Son-of-Man problem by applying Delbert Burkett’s ‘question of reference’ to those Son-of-Man logia that appear in the Sayings Gospel Q. A position is taken that recent philological approaches to the Son-of-Man problem have not been overly convincing, successful or helpful. Similarly, attempting to determine the authenticity of individual Son-of-Man sayings has not led to any form of scholarly consensus. In place of these approaches, a synchronic approach is defended and applied to the Son-of-Man sayings in Q, with interesting results.

  18. Mothers’ Academic Gender Stereotypes and Education-Related Beliefs About Sons and Daughters in African American Families

    Wood, Dana; Kurtz-Costes, Beth; Okeke-Adeyanju, Ndidi; Rowley, Stephanie J.

    2010-01-01

    The role of African American mothers’ academic gender stereotype endorsement in shaping achievement-related expectations for and perceptions of their own children was examined. Mothers (N = 334) of 7th and 8th graders completed measures of expectations for their children’s future educational attainment, perceptions of their children’s academic competence, and academic gender stereotypes. Consistent with hypotheses, mothers held less favorable expectations for sons and perceived sons to be less academically competent than daughters. In addition, mothers reported stereotypes favoring girls over boys in academic domains; stereotype endorsement, in turn, was related to mothers’ educational expectations for and beliefs about the academic competence of their own children, even with youths’ actual achievement controlled. Negative stereotypes about the academic abilities of African American boys may create a negative feedback loop, thereby contributing to the maintenance of the gender gap in African Americans’ educational outcomes.

    Carl Wilhelm Naundorff was buried in 1845 in Delft as Louis Charles, Duc de Normandie, 'Louis XVII'. However, the son of Louis XVI and Marie-Antoinette-Louis XVII--officially died in the Temple of Paris in 1795. In order to resolve the identity of Naundorff, mitochondrial DNA (mtDNA) D-loop sequences of his remains were compared with the sequences obtained from the hairs of two sisters of Marie-Antoinette, Marie-Antoinette herself, and with the sequences obtained from DNA samples of two living maternal relatives. The mtDNA sequence of a bone sample from Naundorff showed two nucleotide differences from the sequences of the three sisters and four differences from the sequences of living maternal relatives. Based on this evidence it becomes very unlikely that Naundroff is the son of Marie-Antoinette.

  1. Meaning Reconstruction Process After Suicide: Life-Story of a Japanese Woman Who Lost Her Son to Suicide.

    Kawashima, Daisuke; Kawano, Kenji

    2017-09-01

    Although Japan has a high suicide rate, there is insufficient research on the experiences of suicide-bereaved individuals. We investigated the qualitative aspects of the meaning reconstruction process after a loss to suicide. We conducted a life-story interview using open-ended questions with one middle-aged Japanese woman who lost her son to suicide. We used a narrative approach to transcribe and code the participant's narratives for analysis. The analysis revealed three meaning groups that structured the participant's reactions to the suicide: making sense of her son's death and life, relationships with other people, and reconstruction of a bond with the deceased. The belief that death is not an eternal split and that there is a connection between the living and the deceased reduced the pain felt by our participant. Furthermore, the narratives worked as scaffolds in the meaning reconstruction process. We discuss our results in the light of cross-cultural differences in the grieving process.

    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

  8. Young Children’s Risk-Taking: Mothers’ Authoritarian Parenting Predicts Risk-Taking by Daughters but Not Sons

    Directory of Open Access Journals (Sweden)

    Erin E. Wood

    2017-01-01

    Full Text Available We investigated how mothers’ parenting behaviors and personal characteristics were related to risk-taking by young children. We tested contrasting predictions from evolutionary and social role theories with the former predicting higher risk-taking by boys compared to girls and the latter predicting that mothers would influence children’s gender role development with risk-taking occurring more in children parented with higher levels of harshness (i.e., authoritarian parenting style. In our study, mothers reported their own gender roles and parenting styles as well as their children’s risk-taking and activities related to gender roles. The results were only partially consistent with the two theories, as the amount of risk-taking by sons and daughters did not differ significantly and risk-taking by daughters, but not sons, was positively related to mothers’ use of the authoritarian parenting style and the girls’ engagement in masculine activities. Risk-taking by sons was not predicted by any combination of mother-related variables. Overall, mothers who were higher in femininity used more authoritative and less authoritarian parenting styles. Theoretical implications as well as implications for predicting and reducing children’s risk-taking are discussed.

  9. Sociosexually unrestricted parents have more sons: a further application of the generalized Trivers-Willard hypothesis (gTWH).

    Science.gov (United States)

    Kanazawa, Satoshi; Apari, Péter

    2009-01-01

    The generalized Trivers-Willard hypothesis (gTWH) proposes that parents who possess any heritable trait which increases male reproductive success at a greater rate than female reproductive success in a given environment will have a higher-than-expected offspring sex ratio, and parents who possess any heritable trait which increases the female reproductive success at a greater rate than male reproductive success in a given environment will have a lower-than-expected offspring sex ratio. One heritable trait which increases the reproductive success of sons much more than that of daughters is unrestricted sociosexual orientation. We therefore predict that parents with unrestricted sociosexual orientation (measured by the number of sexual partners, frequency of sex, and attitudes toward relationship commitment and sexual exclusivity) have a higher-than-expected offspring sex ratio (more sons). We analyse the US General Social Surveys and the National Longitudinal Study of Adolescent Health (Add Health), both with large nationally representative samples. Our analyses support the prediction from the gTWH. One standard deviation increase in unrestrictedness of sociosexual orientation increases the odds of having a son by 12-19% in the representative American samples.

    Jessica I. Elfenbein

    2008-01-01

    Full Text Available From 1860 to 1960, Baltimore was an important center of the men’s ready-to- wear clothing industries. German-speaking Jews created many businesses that manufactured and sold underwear, men’s suits, and specialty items like hats and umbrellas. The straw hat making firm started by M.S. Levy is an interesting example of a Baltimore-based, family-owned niche business that existedfor 90 years, through three generations ofa singlefamily. The M.S. Levy and Sons story has two main chapters. The first covers the period from its founding by Michael Simon Levy in the 1870s through his son Julius’ death in 1926. This is the story of ascension. A premonition about the coming popularity of straw hats, together with a small but important technological breakthrough, positioned a family and a small industry for significant expansion. The second period began in 1930 with the introduction of wool felt hats and the death of William, M.S. Levy’s oldest son, and includes the Great Depression, unionization, merger, third generation leadership, and finally, in 1959, the family’s withdrawal from the industry. This later period, as told by grandsons of the founder, is the story of struggle followed by decline.

    Kristensen, Pål; Heir, Trond; Herlofsen, Pål H; Langsrud, Øyvind; Weisæth, Lars

    2012-01-01

    We prospectively studied parental mental health after suddenly losing a son in a military training accident. Parents (N = 32) were interviewed at 1, 2 and 23 years after the death of their son. The General Health Questionnaire and Expanded Texas Inventory of Grief were self-reported at 1, 2, 5, and 23 years; the Inventory of Complicated Grief was self-reported at 23 years. We observed a high prevalence of psychiatric disorders at 1- and 2-year follow-ups (57% and 45%, respectively), particularly major depression (43% and 31%, respectively). Only one mental disorder was diagnosed at the 23-year follow-up. Grief and psychological distress were highest at 1- and 2-year follow-ups. Spouses exhibited a high concordance of psychological distress. Mothers reported more intense grief reactions than did fathers. The loss of a son during military service may have a substantial impact on parental mental health particularly during the first 2 years after death. Spouses' grief can be interrelated and may contribute to their psychological distress.

  12. Double layers above the aurora

    Two different kinds of double layers were found in association with auroral precipitation. One of these is the so-called electrostatic shock, which is oriented at an oblique angle to the magnetic field in such a way that the perpendicular electric field is much larger than the parallel electric field. This type of double layer is often found at the edges of regions of upflowing ion beams and the direction of the electric fields in the shock points toward the ion beam. The potential drop through the shock can be several kV and is comparable to the total potential needed to produce auroral acceleration. Instabilities associated with the shock may generate obliquely propagating Alfven waves, which may accelerate electrons to produce flickering auroras. The flickering aurora provides evidence that the electrostatic shock may have large temporal fluctuations. The other kind of double layer is the small-amplitude double layer found in regions of upward flowing in beams, often in association with electrostatic ion cyclotron waves. The parallel and perpendicular electric fields in these structures are comparable in magnitude. The associated potentials are a few eV. Since many such double layers are found in regions of upward flowing ion beams, the combined potential drop through a set of these double layers can be substantial

  13. Global effects of double layers

    International Nuclear Information System (INIS)

    Raad, M.A.

    1984-12-01

    Locally the formation of an electrostatic double layer in a current carrying plasma leads to a direct acceleration of particles which may penetrate far into the surrounding medium. The potential across the double layer, giving this acceleration, must be maintained by the external system and is a basic parameter for the local to global coupling. The double layer potential is associated with an electric field parallel to the magnetic field. In general this leads to a magnetohydrodynamic relaxation of the surrounding medium providing the influx of energy which is dissipated by the double layer. The double layer potential is limited as is the maximum possible rate of energy influx. If the global response of the external medium can be represented by an external circuit and if an equivalent circuit element can be found to represent the double layer, for example a negative resistance for intermediate time scales, it is possible to give a description of the dynamics and stability of the whole system.

    Long-term storage of high-level nuclear waste glass in France is expected to occur in an engineered barrier system (EBS) located in a subsurface Callovo-Oxfordian (COx) clay rock formation in the Paris Basin in northeastern France. Understanding the behavior of glass dissolution in the complex system is critical to be able to reliably model the performance of the glass in this complex environment. To simulate this multi-barrier repository scenario in the laboratory, several tests have been performed to measure glass dissolution rates of the simulated high-level nuclear waste glass, SON68, in the presence of COx claystone at 90 °C. Experiments utilized a High-Performance Liquid Chromatography (HPLC) pump to pass simulated Bure site COx pore water through a reaction cell containing SON68 placed between two COx claystone cores for durations up to 200 days. Silicon concentrations at the outlet were similar in all experiments, even the blank experiment with only the COx claystone (∼4 mg/L at 25 °C and ∼15 mg/L at 90 °C). The steady-state pH of the effluent, measured at room temperature, was roughly 7.1 for the blank and 7.3–7.6 for the glass-containing experiments demonstrating the pH buffering capacity of the COx claystone. Dissolution rates for SON68 in the presence of the claystone were elevated compared to those obtained from flow-through experiments conducted with SON68 without claystone in silica-saturated solutions at the same temperature and similar pH values. Additionally, through surface examination of the monoliths, the side of the monolith in direct contact with the claystone was seen to have a corrosion thickness 2.5× greater than the side in contact with the bulk glass powder. Results from one experiment containing {sup 32}Si-doped SON68 also suggest that the movement of Si through the claystone is controlled by a chemically coupled transport with a Si retention factor, K{sub d}, of 900 mL/g.

    In the United States, nearly half of high school students are sexually active, and adolescents experience high rates of unintended pregnancy and sexually transmitted diseases. Parents can have an important influence on their children's sexual behaviour, but many parents do not talk with their children about sexual topics. Research has shown significant differences in parent-child communication about sexual topics depending on the gender of both the parent and the child. Little is known, however, about the reasons for these gender differences. The purpose of this paper is to describe how factors associated with parent-child communication about sexual topics differ by gender. Data are from a nationwide online survey with 829 fathers and 1,113 mothers of children aged 10 to 14. For each of the four gender groups (fathers of sons, fathers of daughters, mothers of sons, mothers of daughters), we calculated the distribution of responses to questions assessing (1) parent-child communication about sex-related topics, and (2) factors associated with that communication. We used chi-square tests to determine whether the distributions differed and the false discovery rate control to reduce the likelihood of type I errors. With both sons and daughters, fathers communicated less about sexual topics than mothers did. Fathers also had lower levels of many characteristics that facilitate communication about sex (e.g., lower self-efficacy and lower expectations that talking to their children about sex would have positive outcomes). Compared with parents of sons, parents of daughters (both mothers and fathers) talked more about sexual topics, were more concerned about potential harmful consequences of sexual activity, and were more disapproving of their child having sex at an early age.

  17. Force interaction and 3D pole movement in double poling.

    Stöggl, T; Holmberg, H-C

    2011-12-01

    The aim of this study was to analyze double poling using combined kinetic and 3D kinematic analysis at high skiing speeds as regards pole force components, pole angles and pole behavior during the poling and swing phase. The hypothesis was that a horizontal pole force is more predictive for maximal skiing speed (V(max)) than the resultant pole force. Sixteen elite skiers performed a double-poling V(max) test while treadmill roller skiing. Pole forces and 3D kinematics of pole movement at a speed of 30 km/h were analyzed and related to V(max). The duration of the "preparation phase" showed the strongest relationship with V(max) (r=0.87, Pmax) compared with the resultant pole force. Impact force was not related to V(max). At high skiing speeds, skiers should aim to combine high pole forces with appropriate timing of pole forces and appropriate pole and body positions during the swing and poling phase. The emphasis in training should be on the development of specific strength capacities for pole force production and the utilization of these capacities in double-poling training sessions. © 2011 John Wiley & Sons A/S.

  3. Alternate Double Single Track Lines

    Energy Technology Data Exchange (ETDEWEB)

    Moraga Contreras, P.; Grande Andrade, Z.; Castillo Ron, E.

    2016-07-01

    The paper discusses the advantages and shortcomings of alternate double single track (ADST) lines with respect to double track lines for high speed lines. ADST lines consists of sequences of double and single track segments optimally selected in order to reduce the construction and maintenance costs of railway lines and to optimize the timetables used to satisfy a given demand. The single tracks are selected to coincide with expensive segments (tunnels and viaducts) and the double tracks are chosen to coincide with flat areas and only where they are necessary. At the same time, departure times are adjusted for trains to cross at the cheap double track segments. This alternative can be used for new lines and also for existing conventional lines where some new tracks are to be constructed to reduce travel time (increase speed). The ADST proposal is illustrated with some examples of both types (new lines and where conventional lines exist), including the Palencia-Santander, the Santiago-Valparaíso-Viña del Mar and the Dublin-Belfast lines, where very important reductions (90 %) are obtained, especially where a railway infrastructure already exist.

  4. On the physics of relativistic double layers

    International Nuclear Information System (INIS)

    Carlqvist, P.

    1982-06-01

    A model of a strong, time-independent, and relativistic double layer is studied. Besides double layers having the electric field parallel to the current the model also describes a certain type of oblique double layers. The 'Langmuir condition' (ratio of ion current density to electron current density) as well as an expression for the potential drop of the double layer are derived. Furthermore, the distribution of charged particles, electric field, and potential within the double layer are clarified and discussed. It is found that the properties of relativistic double layers differ substantially from the properties of corresponding non-relativistic double layers. (Author)

    Full Text Available Background During childhood, parents are the first and most important individuals who form the base of the content of gender stereotypes in children. A parent’s expectations about the extent a child’s behaviour should be line with gender stereotypes also depends on the intensity of a parent’s sexism. A parent’s sexism may be exhibited in parental attitudes. Hence, in our study we analysed the relationship between parental ambivalent sexism and parental attitudes within dyads of mothers and fathers with a special focus on the role of the gender of both parents and children. Participants and procedure Two hundred and ninety-four couples of parents of five-year-olds (153 girls, 141 boys participated. The Ambivalent Sexism Inventory (ASI was used to measure levels of sexism, and the Parental Attitudes Scale (SPR was used to assess parental attitudes. Results In terms of the profile of parental attitudes, regardless of the child’s sex, mothers and fathers scored highest for inconsequent and demanding attitudes, and lowest for overprotective and autonomy attitudes. The child’s sex is also not important for the overall levels of parents’ sexism – fathers exhibit higher levels of hostile sexism in comparison to mothers. Only the mothers’ education level is important for levels of sexism – women with higher education exhibited the lowest levels of hostile sexism. The child’s sex moderates relationships between parents’ sexism and parental attitudes. In the case of mothers of sons, the intensity of benevolent sexism is negatively related to overprotective and demanding attitudes. The more educated the mothers of sons, the more demanding they were. For fathers of sons, the inconsequence attitude increases under the influence of both hostile and benevolent sexism. Among fathers of daughters, hostile sexism strengthens the overprotective attitude, while levels of both benevolent and hostile sexism as well as education influence the

    2013-01-01

    We describe geometric construction underlying the Lagrangian actions for non-Grassmann spinning particles proposed in our recent works. If we discard the spatial variables (the case of frozen spin), the problem reduces to formulation of a variational problem for Hamiltonian system on a manifold with so(n) Lie-Poisson bracket. To achieve this, we identify dynamical variables of the problem with coordinates of the base of a properly constructed fiber bundle. In turn, the fiber bundle is embedded as a surface into the phase space equipped with canonical Poisson bracket. This allows us to formulate the variational problem using the standard methods of Dirac theory for constrained systems.

    2018-01-01

    The Double Brewster angle effect (DBE) is an extension of the Brewster angle to double reflection on two orthogonal dielectric surfaces. It results from the combination of two pseudo-Brewster angles occurring in complementary incidence angles domains. It can be observed for a large range of incidence angles provided that double bounces mechanism is present. As a consequence of this effect, we show that the reflection coefficient at VV polarization can be at least 10 dB lower than the reflection coefficient at HH polarization over a wide range of incidence angle - typically from 20 to 70∘. It is experimentally demonstrated using a Synthetic Aperture Radar (SAR) image that this effect can be seen on buildings and forests. For large buildings, the difference can reach more than 20 dB. xml:lang="fr"

    This book contains spectra of the doubly charged positive ions (dications) of some 75 molecules, including the major constituents of terrestrial and planetary atmospheres and prototypes of major chemical groups. It is intended to be a new resource for research in all areas of molecular spectroscopy involving high energy environments, both terrestrial and extra-terrestrial. All the spectra have been produced by photoionisation using laboratory lamps or synchrotron radiation and have been measured using the magnetic bottle time-of-flight technique by coincidence detection of correlated electron pairs. Full references to published work on the same species are given, though for several molecules these are the first published spectra. Double ionisation energies are listed and discussed in relation to the molecular electronic structure of the molecules. A full introduction to the field of molecular double ionisation is included and the mechanisms by which double photoionisation can occur are examined in detail. A p...

    2008-09-01

    Sexual imprinting on discrete variation that serves the identification of species, morphs or sexes is well documented. By contrast, sexual imprinting on continuous variation leading to individual differences in mating preferences within a single species, morph and sex has been studied only once (in humans). We measured female preferences in a captive population of wild-type zebra finches. Individual cross-fostering ensured that all subjects grew up with unrelated foster parents and nest mates. Females from two cohorts (N = 113) were given a simultaneous choice between (two or four) unfamiliar males, one of which was a genetic son of their foster parents (SFP). We found no significant overall preference for the SFP (combined effect size d = 0.14 +/- 0.15). Additionally, we tested if foster parent traits could potentially explain between-female variation in preferences. However, neither the effectiveness of cooperation between the parents nor male contribution to parental care affected female preferences for the son of the foster father. We conclude that at least in zebra finches sexual imprinting is not a major source of between-individual variation in mating preferences.

  19. Application of the GRAAL model to leaching experiments with SON68 nuclear glass in initially pure water

    Frugier, P.; Chave, T.; Gin, S.; Lartigue, J.-E.

    2009-01-01

    Based on a review of the current state of knowledge concerning the aqueous alteration of SON68 nuclear glass we have proposed a mechanistic model, GRAAL (Glass Reactivity with Allowance for the Alteration Layer) [P. Frugier, S. Gin, Y. Minet, T. Chave, B. Bonin, N. Godon, J.E. Lartigue, P. Jollivet, A. Ayral, L. De Windt, G. Santarini, J. Nucl. Mater. 380 (2008) 8]. This article describes how the GRAAL model hypotheses are solved using a calculation code coupling chemistry and transport. The geochemical solution of this model combines three major phenomena: chemical equilibria in solution, water and ion transport by convection or diffusion, and element diffusion through the passivating reactive interphase. The model results are compared with experimental data for SON68 glass leached in initially pure water both in a closed system and in renewed media. The comparison shows the model very satisfactorily accounts for variations in the pH and the element concentrations in solution as a function of time, the glass surface area in contact with solution, and the solution renewal rate. This success is due to the fact that the diffusion of elements through the alteration gel is taken into account in the model. This mechanism cannot be disregarded under most experimental conditions - if only to predict the solution pH - and must therefore be an integral part of the geochemical model.

    Burzyńska Katarzyna

    2017-12-01

    Full Text Available This article investigates the intersections between Shakespeare’s Hamlet and a popular TV series Sons of Anarchy (SOA, loosely based on the Shakespearean original. The crime drama series revolves around an outlaw motorcycle club that literally “rules” a fictional town in California like an old royal family with its own brutal dynastic power squabbles and dark family secrets. The club is governed by an unscrupulous President Clay and an equally violent, though more conflicted, Vice President Jax Teller, the son of the late President, who had died in mysterious circumstances. In the article I argue that the popularity of the series lies not in its graphic scenes of violence, over-the-top Harley chases, and sex intrigues, but rather in its Shakespearean and Renaissance structure. SOA, dubbed as “Hamlet on Harleys”1, is an appropriation rather than an adaptation of Shakespeare’s tragedy, which makes it a truly transmedial phenomenon. The article investigates a fascinating blend of seemingly marginal elements of modern American culture and the canonical British tragedy. It also addresses the connections between the lifestyles of the so called outlaw MC clubs and the early modern family structure as presented in Hamlet, focusing on the issues of power and gender relations.

    Routine administration of the quadrivalent human papillomavirus (HPV) vaccine has been recommended for 11-12-year-old males since 2011, but coverage remains low. In a U.S. national sample of parents of 11-17-year-old males (n=779), 78.6% of parents reported their sons had not received the HPV vaccine. The most common reason for non-vaccination (56.7%) was "My doctor or healthcare provider has not recommended it." Parents citing only logistical reasons for non-vaccination (e.g., lack of recommendation, access, or education, n=384) reported significantly higher vaccine acceptability than parents reporting a combination of attitudinal (e.g., concerns about vaccine safety or efficacy) and logistical barriers (n=92), while parents citing only attitudinal barriers (n=73) reported the lowest level of vaccine acceptability. In sum, many parents are willing but have not vaccinated sons due to logistical barriers, most commonly lack of healthcare provider recommendation. These findings have important implications for increasing HPV vaccination coverage among adolescent males. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Full Text Available Este artículo analizó los conceptos y medidas de pobreza. A partir de esta perspectiva, se estudió quiénes son pobres en Colombia y qué características de los hogares determinan dicha condición para el 2003. A partir de la Encuesta de Calidad de Vida, se realizó un análisis logit para identifi car y medir la incidencia de algunos factores en la probabilidad de que un hogar sea clasifi cado como pobre. Estas estimaciones mostraron que los hogares que tienen más probabilidad de considerarse como pobres son aquellos en los que los jefes de hogar eran analfabetas, mujeres, los que se ocuparon en labores agrícolas o que hacían parte de alguna etnia. Adicionalmente, se encontró que los hogares que tenían menores de 12 años tuvieron más de probabilidad de ser pobres. Finalmente, los hogares cuyo jefe de hogar tenía mayor nivel educativo, tenían menor probabilidad de ser pobres, siendo mayor el efecto educativo de su cónyuge.

  3. Expression of multiple sexual signals by fathers and sons in the East-Mediterranean barn swallow: are advertising strategies heritable?

    The level of expression of sexually selected traits is generally determined by genes, environment and their interaction. In species that use multiple sexual signals which may be costly to produce, investing in the expression of one sexual signal may limit the expression of the other, favoring the evolution of a strategy for resource allocation among signals. As a result, even when the expression of sexual signals is condition dependent, the relative level of expression of each signal may be heritable. We tested this hypothesis in the East-Mediterranean barn swallow (Hirundo rustica transitiva), in which males have been shown to express two uncorrelated sexual signals: red-brown ventral coloration, and long tail streamers. We show that variation in both signals may partially be explained by age, as well as by paternal origin (genetic father-son regressions), but that the strongest similarity between fathers and sons is the relative allocation towards one trait or the other (relative expression index), rather than the expression of the traits themselves. These results suggest that the expression of one signal is not independent of the other, and that genetic strategies for resource allocation among sexual signals may be selected for during the evolution of multiple sexual signals.

    Congenital contractural arachnodactyly (Beals syndrome) is a rare autosomal dominantly inherited connective tissue disorder characterized by flexion contractures, arachnodactyly, crumpled ears, and mild muscular hypoplasia. Here, a father and son with congenital contractural arachnodactyly features were identified. After sequencing 15 exons (22 to 36) of the FBN2 gene, a novel mutation (C1425Y) was found in exon 33. This de novo mutation presented first in the father and was transmitted to his son, but not in the other 14 unaffected family members and 365 normal people. The C1425Y mutation occurs at the 19th cbEGF domain. Cysteines in this cbEGF domain are rather conserved in species, from human down to ascidian. The cbEGF12-13 in human FBN1 was employed as the template to perform homology modeling of cbEGF18-19 of human FBN2 protein. The mutation has also been evaluated by further prediction tools, for example, SIFT, Blosum62, biochemical Yu's matrice, and UMD-Predictor tool. In all analysis, the mutation is predicted to be pathogenic. Thus, the structure destabilization by C1425Y might be the cause of the disorder.

  5. (Alpha, gamma) irradiation effect on the alteration of high-level radioactive wastes matrices (UO2, hollandite, glass SON68)

    2007-06-01

    The aim of this work is to determine the effect of irradiation on the alteration of high level nuclear waste forms matrices. The matrices investigated are UO 2 to simulate the spent fuel, the hollandite for the specific conditioning of Cs, and the inactive glass SON68 representing the nuclear glass R7T7) The alpha irradiation experiments on UO 2 colloids in aqueous carbonate media have enabled to distinguish between the oxidation of UO 2 matrix as initial and dissolution as subsequent step. The simultaneous presence of carbonate and H 2 O 2 (product resulting from water radiolysis) increased the dissolution rate of UO 2 to its maximum value governed by the oxidation rate. ii) The study of hollandite alteration under gamma irradiation confirmed the good retention capacity for Cs and Ba. Gamma irradiation had brought only a little influence on releasing of Cs and Ba in solution. Electronic irradiation had conducted to the amorphization of the hollandite only for a dose 1000 times higher than the auto-induced dose of Ba over millions of years. iii) The experiences of glass irradiation under alpha beam and of helium implantation in the glass SON68 were analyzed by positon annihilation spectroscopy. No effect has been observed on the solid surface for an irradiation dose equal to 1000 years of storage. (author)

  6. When mothers make sons sexy: maternal effects contribute to the increased sexual attractiveness of extra-pair offspring.

    2012-03-22

    Quality differences between offspring sired by the social and by an extra-pair partner are usually assumed to have a genetic basis, reflecting genetic benefits of female extra-pair mate choice. In the zebra finch (Taeniopygia guttata), we identified a colour ornament that is under sexual selection and appears to have a heritable basis. Hence, by engaging in extra-pair copulations with highly ornamented males, females could, in theory, obtain genes for increased offspring attractiveness. Indeed, sons sired by extra-pair partners had larger ornaments, seemingly supporting the genetic benefit hypothesis. Yet, when comparing ornament size of the social and extra-pair partners, there was no difference. Hence, the observed differences most likely had an environmental basis, mediated, for example, via differential maternal investment of resources into the eggs fertilized by extra-pair and social partners. Such maternal effects may (at least partly) be mediated by egg size, which we found to be associated with mean ornament expression in sons. Our results are consistent with the idea that maternal effects can shape sexual selection by altering the genotype-phenotype relationship for ornamentation. They also caution against automatically attributing greater offspring attractiveness or viability to an extra-pair mate's superior genetic quality, as without controlling for differential maternal investment we may significantly overestimate the role of genetic benefits in the evolution of extra-pair mating behaviour.

    A review is presented of the main results of the theoretical work on electrostatic double layers. The general properties of double layers are first considered. Then the time-independent double layer is discussed. The discussion deals with the potential drop, the thickness, and some necessary criteria for the existence and stability of the layer. As a complement to the study of the timeindependent double layer a few remarks are also made upon the timedependent double layer. Finally the question of how double layers are formed and maintained is treated. Several possible formation mechanisms are considered. (author)

  19. Introducing SONS, a tool for operational taxonomic unit-based comparisons of microbial community memberships and structures.

    2006-10-01

    The recent advent of tools enabling statistical inferences to be drawn from comparisons of microbial communities has enabled the focus of microbial ecology to move from characterizing biodiversity to describing the distribution of that biodiversity. Although statistical tools have been developed to compare community structures across a phylogenetic tree, we lack tools to compare the memberships and structures of two communities at a particular operational taxonomic unit (OTU) definition. Furthermore, current tests of community structure do not indicate the similarity of the communities but only report the probability of a statistical hypothesis. Here we present a computer program, SONS, which implements nonparametric estimators for the fraction and richness of OTUs shared between two communities.

    This article summarizes the present state of knowledge concerning aqueous alteration of R7T7-type nuclear containment glasses, represented mainly by the inactive reference glass designated SON68. Based on this review, we propose to describe the glass alteration kinetics up to and including the final residual rate regime by means of a new mechanistic model known as GRAAL (glassreactivitywithallowanceforthealterationlayer). Phenomenological analysis findings are reviewed for the various glass alteration regimes: interdiffusion, initial rate, rate drop, residual rate and, under very particular circumstances, resumption of alteration. These alteration regimes are associated with predominant mechanisms. Published work interpreting and modeling these mechanisms was examined in detail. There is a broad consensus on the general mechanisms of the initial rate and even the interdiffusion regime, whereas the mechanisms controlling the rate drop remain a subject of dispute not only with regard to nuclear glasses but also for the dissolution of silicate minerals. The reaction affinity responsible for the rate drop is expressed differently by different authors and depending on the underlying theories. The disagreement concerns the nature of the phase (glass or gel) or the activated complex controlling the rate drop, which in turn determines the elements that must be taken into account in the overall affinity term. Progress in recent years, especially in identifying the mechanisms responsible for the residual rate, has shed new light on these issues, allowing us to propose new theoretical foundations for modeling the different kinetic regimes of SON68 nuclear glass dissolution. The GRAAL model considers that water diffusion in the passivating reaction zone (the gel formed under saturation conditions) is a rate-limiting step in the overall glass dissolution kinetics. Moreover, this passivation zone is a soluble phase whose stability is directly dependent on the nature of the

    More than forty years after the first discovery of a double neutron star, we still havent found many others but a new survey is working to change that.The Hunt for PairsThe observed shift in the Hulse-Taylor binarys orbital period over time as it loses energy to gravitational-wave emission. [Weisberg Taylor, 2004]In 1974, Russell Hulse and Joseph Taylor discovered the first double neutron star: two compact objects locked in a close orbit about each other. Hulse and Taylors measurements of this binarys decaying orbit over subsequent years led to a Nobel prize and the first clear evidence of gravitational waves carrying energy and angular momentum away from massive binaries.Forty years later, we have since confirmed the existence of gravitational waves directly with the Laser Interferometer Gravitational-Wave Observatory (LIGO). Nonetheless, finding and studying pre-merger neutron-star binaries remains a top priority. Observing such systems before they merge reveals crucial information about late-stage stellar evolution, binary interactions, and the types of gravitational-wave signals we expect to find with current and future observatories.Since the Hulse-Taylor binary, weve found a total of 16 additional double neutron-star systems which represents only a tiny fraction of the more than 2,600 pulsars currently known. Recently, however, a large number of pulsar surveys are turning their eyes toward the sky, with a focus on finding more double neutron stars and at least one of them has had success.The pulse profile for PSR J1411+2551 at 327 MHz.

    Seventy patients with clinical wrist problems were studied with double-compartment wrist arthrography. Midcarpal and radiocarpal compartment arthrograms were obtained in all patients. Digital subtraction technique was used to subtract out contrast from the first compartmental injection. Digital technique also allowed a dynamic record of each injection, which helped determine sites of intercompartmental communication. Postarthrography exercises recorded on videotape were performed after each injection. There were 34 normal studies. Abnormalities in the other 36 patients included: scapholunate communication (n = 9), lunatotriquetral communication (n = 6), communication with tendon sheaths (n = 4), communication with distal radioulnar compartment (n = 14), abnormal synovium process (n = 9), and communication through the radial or ulnar collateral ligament (n = 3).

    2015-01-01

    Full Text Available T. S. Eliot's "La Figlia Che Piange" (1916 is a curious anomaly in his early works. It stands out as a love poem of outstanding grace portraying a more positive relationship to the feminine compared to other poems contemporaneous with its writing such as "The Love Song of St. Sebastian" (1914 and "Hysteria" (1915. This essay shows the import of Eliot's chosen epigraph for "La Figlia" taken from Virgil's Aeneid to have been largely neglected or misread by critics. As a consequence, it argues that critical readings have crucially missed the presence of a shrouded maternal aspect within the poem. Through the lens of Lacanian psychoanalysis and the work of adherents to Lacanian theory — such as Bruce Fink, Shoshana Felman and Slavoj Zizek — this paper newly argues that the poem's meditation on the issues of union and separation between two lovers is in fact a screen for deeper unconscious ambivalent feelings between mother and son. That is to say, Eliot's "La Figlia Che Piange" shows a failed attempt to reconstruct, traverse and separate from the "fundamental fantasy" unconsciously orientating the male speaker of the poem and his desire.

  9. Tensor estimation for double-pulsed diffusional kurtosis imaging.

    Shaw, Calvin B; Hui, Edward S; Helpern, Joseph A; Jensen, Jens H

    2017-07-01

    Double-pulsed diffusional kurtosis imaging (DP-DKI) represents the double diffusion encoding (DDE) MRI signal in terms of six-dimensional (6D) diffusion and kurtosis tensors. Here a method for estimating these tensors from experimental data is described. A standard numerical algorithm for tensor estimation from conventional (i.e. single diffusion encoding) diffusional kurtosis imaging (DKI) data is generalized to DP-DKI. This algorithm is based on a weighted least squares (WLS) fit of the signal model to the data combined with constraints designed to minimize unphysical parameter estimates. The numerical algorithm then takes the form of a quadratic programming problem. The principal change required to adapt the conventional DKI fitting algorithm to DP-DKI is replacing the three-dimensional diffusion and kurtosis tensors with the 6D tensors needed for DP-DKI. In this way, the 6D diffusion and kurtosis tensors for DP-DKI can be conveniently estimated from DDE data by using constrained WLS, providing a practical means for condensing DDE measurements into well-defined mathematical constructs that may be useful for interpreting and applying DDE MRI. Data from healthy volunteers for brain are used to demonstrate the DP-DKI tensor estimation algorithm. In particular, representative parametric maps of selected tensor-derived rotational invariants are presented. Copyright © 2017 John Wiley & Sons, Ltd.

    Our study objective was to survey female carriers for Duchenne and Becker muscular dystrophy to identify barriers to carrier testing and the impact of carrier risk knowledge on cardiac and reproductive health management. We surveyed women who have or had biological sons with Duchenne or Becker muscular dystrophy and were enrolled in the US DuchenneConnect patient registry, with questions assessing knowledge of carrier status and recurrence risk, knowledge of care standards for carriers, and barriers to testing. Of the 182 eligible respondents, 25% did not know their carrier status and 14% incorrectly classified themselves as not at risk. Cost of testing was the most commonly identified barrier to testing. Women reporting unknown carrier status were 13 times as likely to express uncertainty regarding their recurrence risk compared to women reporting positive carrier status. 37% of women at an increased risk for cardiomyopathy had never had an echocardiogram. Women who were certain of their positive carrier status were twice as likely to have had an echocardiogram in the last five years compared to women with unknown carrier status. Future research on reducing barriers to counseling and carrier testing, such as cost, may improve care standard adherence. Copyright © 2016 Elsevier B.V. All rights reserved.

El análisis económico ha desarrollado un conjunto de modelos de mercado que permiten explicar el comportamiento de los precios, aunque los mercados reales divergen sustancialmente de los modelos teóricos. La regulación de precios está justificada por los llamados “fallos de mercado”; la regulación de precios basada en el costo de producción, la modalidad de control de precios más tradicional, ha caído en desuso a favor de los sistemas de precios de referencia internacionales y por la fijación del precio basada en el valor.

    2005-04-01

    Williams-Beuren syndrome (WBS) is a neurodevelopmental microdeletion disorder that usually occurs sporadically due to its location within a highly repetitive genomic region that is unstable and prone to unequal cross-over during meiosis. The consequential loss of chromosomal material includes approximately 1.5 Mb of DNA at 7q11.23. Whilst cases of dominant inheritance have been described in the literature, there have been few reports of molecular confirmation and none have carried out detailed genotyping. We describe a Bulgarian father and son with WBS detected by fluorescent in situ hybridisation (with an elastin gene probe) and loss of heterozygosity mapping using microsatellite markers located in the critical region. These individuals appear to have a common WBS heterozygous deletion, confirming the expected dominant transmission and adding to the few familial cases reported. The deletion includes the gene FKBP6 which has recently been shown to play a role in homologous chromosome pairing in meiosis and male fertility in mouse models. Homozygous Fkbp6 -/- male mice are infertile and our data suggests that haploinsufficiency for FKBP6 does not appear to preclude male fertility in WBS, although male infertility involving this gene has the potential to follow the mouse model as a human autosomal recessive condition.

    Despite research that suggests parental communication may help deter high-risk sexual behavior among adolescents, parents report a lack of confidence in their ability to answer sexually related questions. The purpose of this study was to test the effect of a multimedia intervention on outcome expectations and perceived self-efficacy for the sex educator role for parents of African American adolescent males. A pilot study using mixed methods was conducted. A nonprobability sample (N = 61) was obtained from a large urban community using a combination of convenience and snowball recruitment methods. Self-efficacy and outcome expectations were measured using self-reported questionnaires. A multimedia intervention for use at home and incorporating an audio CD and associated activities was implemented over a 3-week time period. Outcome expectations and self-efficacy both significantly improved after the intervention (p parents' outcome expectancy and self-efficacy for talking about sex with adolescent sons. © 2013 Wiley Periodicals, Inc.

    To predict the long-term behavior of high-level radioactive waste glass, it is necessary to study aqueous dissolution of the glass matrix under geological repository conditions. The present article focuses on SON68 (an inactive surrogate of the R7T7 glass) glass alteration in synthetic clayey groundwater at 70 °C. Experiments in deionized water as reference were also performed in the same conditions. Results are in agreement with those of previous studies showing that magnesium present in the solution is responsible for higher glass alteration. This effect is transient and pH-dependent: Once all the magnesium is consumed, the glass alteration rate diminishes. Precipitation of magnesium silicate of the smectite group seems to be the main factor for the increased glass alteration. A pH threshold of 7.5-7.8 was found, above which precipitation of these magnesium silicates at 70 °C is possible. TEM observations reveal that magnesium silicates grow at the expense of the passivating gel, which partly dissolves, forming large pores which increase mass transfer between the reacting glass surface and the bulk solution.

  17. Household opportunity costs of protecting and developing forest lands in Son La and Hoa Binh Provinces, Vietnam

    Full Text Available Vietnam has pilot-tested a payment for forest environmental services (PFES program in an effort to restore and protect forest areas, some of which have been severely degraded by the excessive cutting of trees by small-scale farmers planting annual crops on steep, sloping lands. The pilot program implemented in southern Vietnam seems to be successful, yet the program in northern Vietnam has not produced the desired rates of planting and maintaining forest areas. The reasons for these mixed results include differences in socio-economic characteristics and also the production and marketing opportunities available to rural households in the project areas. To gain insight regarding program participation, we examine the household-level opportunity costs of planting and ­maintaining small plots of forest trees in northern Vietnam. We find that small-scale farmers in Hoa Binh Province, with limited financial resources, prefer the annual revenue stream provided by crops such as maize and cassava, rather than waiting for 7 years to obtain revenue from a forest planting. Farmers in Son La Province, with limited access to markets, prefer annual crops because they are not able to sell bamboo shoots and other forest products harvested from their small plots. In both provinces, the payments offered for planting and maintaining forest trees are smaller than the opportunity costs of planting and harvesting annual crops. Thus, most households likely would choose not to participate in the PFES program, at current payment rates, if given the opportunity to decline.

  18. How parasitoid females produce sexy sons: a causal link between oviposition preference, dietary lipids and mate choice in Nasonia.

    Sexual selection theory predicts that phenotypic traits used to choose a mate should reflect honestly the quality of the sender and thus, are often costly. Physiological costs arise if a signal depends on limited nutritional resources. Hence, the nutritional condition of an organism should determine both its quality as a potential mate and its ability to advertise this quality to the choosing sex. In insects, the quality of the offspring's nutrition is often determined by the ovipositing female. A causal connection, however, between the oviposition decisions of the mother and the mating chances of her offspring has never been shown. Here, we demonstrate that females of the parasitic wasp Nasonia vitripennis prefer those hosts for oviposition that have been experimentally enriched in linoleic acid (LA). We show by (13)C-labelling that LA from the host diet is a precursor of the male sex pheromone. Consequently, males from LA-rich hosts produce and release higher amounts of the pheromone and attract more virgin females than males from LA-poor hosts. Finally, males from LA-rich hosts possess three times as many spermatozoa as those from LA-poor hosts. Hence, females making the right oviposition decisions may increase both the fertility and the sexual attractiveness of their sons.

    Son of sevenless (Sos) is a dual specificity guanine nucleotide exchange factor (GEF) that regulates both Ras and Rho family GTPases and thus is uniquely poised to integrate signals that affect both gene expression and cytoskeletal reorganization. Here, using genetics, biochemistry, and cell biology, we demonstrate that Sos is recruited to the plasma membrane, where it forms a ternary complex with the Roundabout receptor and the SH3-SH2 adaptor protein Dreadlocks (Dock) to regulate Rac-dependent cytoskeletal rearrangement in response to the Slit ligand. Intriguingly, the Ras and Rac-GEF activities of Sos can be uncoupled during Robo-mediated axon repulsion; Sos axon guidance function depends on its Rac-GEF activity, but not its Ras-GEF activity. These results provide in vivo evidence that the Ras and RhoGEF domains of Sos are separable signaling modules and support a model in which Robo recruits Sos to the membrane via Dock to activate Rac during midline repulsion.

  20. Who is entitled to double effect?

    Boyle, J

    1991-10-01

    The doctrine of double effect continues to be an important tool in bioethical casuistry. Its role within the Catholic moral tradition continues, and there is considerable interest in it by contemporary moral philosophers. But problems of justification and correct application remain. I argue that if the traditional Catholic conviction that there are exceptionless norms prohibiting inflicting some kinds of harms on people is correct, then double effect is justified and necessary. The objection that double effect is superfluous is a rejection of that normative conviction, not a refutation of double effect itself. This justification suggests the correct way of applying double effect to controversial cases. But versions of double effect which dispense with the absolutism of the Catholic tradition lack justification and fall to the objection that double effect is an unnecessary complication.

    For the purpose of proving the conservation of norm in the field theory of complex mass proposed by one of the present authors, a new space is introduced where the state vectors have a double structure and the norms are complex numbers in general. The new space contains the Hilbert space as a subspace where the norms are real and positive. It is shown that the S-matrix transforms a vector of the Hilbert space into a vector of the same space. Other states in the new space may appear as intermediate virtual states. In this way the field theory of complex mass is formally proved to be physically interpretable. (auth.)

    Double-walled steam generator tubing for the steam generators of a liquid metal cooled fast breeder reactor prevents sliding between the surfaces due to a mechanical interlock. Forces resulting from differential thermal expansion between the outer tube and the inner tube are insufficient in magnitude to cause shearing of base metal. The interlock is formed by jointly drawing the tubing, with the inside wall of the outer tube being already formed with grooves. The drawing causes the outer wall of the inner tube to form corrugations locking with the grooves. (author)

    The Double Beta Decay, and especially ({beta}{beta}){sub 0{nu}} mode, is an excellent test of Standard Model as well as of neutrino physics. From experimental point of view, a very large number of different techniques are or have been used increasing the sensitivity of this experiments quite a lot (the factor of 10{sup 4} in the last 20 years). In future, in spite of several difficulties, the sensitivity would be increased further, keeping the interest of this very important process. (author) 4 figs., 5 tabs., 21 refs.

    The magnetogasdynamical behaviour of plasmoids moving through an ambient gas is investigated numerically with a two-dimensional code, based on the SHASTA scheme. The astrophysical importance of this study lies in the observed extended extragalactic radio sources. It is assumed that plasma clouds with cylinder symmetry are ejected from the nucleus of a galaxy. Their large-scale evolution in the intergalactic medium (IGM) is followed. The gas dynamics of an ejected cloud, the magnetogasdynamics of ejected clouds, the Christiansen-Pacholczyk-Scott picture for radio galaxies and the shear layers in double radio sources are studied.

Par RT-PCR, nous avons clone un ADNc codant pour les quatre domaines de l'IGF-l mature. La protéine présente 70 à 96 % d'identité avec les autres IGF-I de vertébrés. Le clonage de la séquence codante entière du récepteur a nécessité la construction d'une banque d'ADNc d'embryons de turbots. Le récepteur est organisé en domaines dont la taille et les caractéristiques sont semblables à celles des autres récepteurs aux IGF de type 1 décrits chez les mammifères et le poulet. La région catalytique est particulièrement conservée. Dans certains domaines, notamment dans la région C-terminale du précurseur, quelques différences qui pourraient avoir une importance fonctionnelle sont cependant observées. Enfin, par RT-PCR, nous avons mis en évidence une régulation ontogénique du statut de polyadénylation des ARNm IGF-1R.

    Full Text Available Le Léviathan de Hobbes [1651] a subi de nombreuses attaques, au point qu’il est jugé responsable de la grande peste de 1665 et de l’incendie de Londres l’année suivante et que le parlement ouvre une procédure contre l’ouvrage. Aussi, lorsqu’en 1666, Thomas Hobbes veut publier la traduction latine de ce livre, il y adjoint trois appendices. La version latine de l’œuvre est généralement jugée plus acceptable que le texte originaire anglais. En étudiant la manière dont Hobbes traite de son matérialisme dans ces appendices, je tente de montrer que les addenda latins ne constituent en aucune manière un retour en arrière du texte, mais que le philosophe enrobe simplement davantage des propos que, par ailleurs, il rend plus radicaux.Hobbes’s Leviathan [1651] has been critiqued so much that it was held responsible for the Great Plague of 1665 and the Fire of London during the following year, resulting in the Parliament instituting proceedings against the book. Therefore, when in 1666 Thomas Hobbes wanted to publish a Latin translation of this book, he added three appendices. Generally, the Latin version of the work is considered more acceptable than the English original text. By studying how Hobbes deals with his materialism in these appendices, I try to show that the Latin additions are in no way a reversal of the text, but that the philosopher simply veiled more propositions, while at the same time making them more radical.

Algunos errores congénitos del metabolismo (ECM han sido asociados al SMSL y/o a episodios aparentemente letales EAL, aunque la mayoría de ellos suelen tener alguna expresión clínica que los hace potencialmente diagnosticables antes de la muerte, lo que permite ser descartados de entre las causas del SMSL. De ellos, los más estrechamente relacionados con el SMSL son los trastornos de la betaoxidación mitocondrial de ácidos grasos. Solo del 3 al 5 % de los SMSL pueden guardar relación con ECM. El mayor impacto que representa el conocimiento de la asociación de SMSL y estos trastornos, es precisamente la posibilidad de su prevención. El personal médico debe conocer que la más eficiente forma de prevenir el SMSL relacionado con los ECM, es la búsqueda activa de lactantes de riesgo al realizar una exhaustiva anamnesis. Estos casos deben ser objeto de estudios metabólicos especializados, para lo cual es imprescindible conocer los requisitos de obtención, conservación y traslado de muestras al Laboratorio de Referencia.

    Huntington's disease (HD) is an autosomal dominant neurodegenerative disease caused by a trinucleotide (CAG) repeat expansion in huntingtin (HTT) on chromosome 4. Anticipation can cause longer repeat expansions in children of HD patients. Juvenile Huntington's disease (JHD), defined as HD arising before age 20, accounts for 5-10% of HD cases, with cases arising in the first decade accounting for approximately 1%. Clinically, JHD differs from the predominately choreiform adult onset Huntington's disease (AOHD) with variable presentations, including symptoms such as myoclonus, seizures, Parkinsonism, and cognitive decline. The neuropathologic changes of AOHD are well characterized, but there are fewer reports that describe the neuropathology of JHD. Here we report a case of a six-year-old boy with paternally-inherited JHD caused by 169 CAG trinucleotide repeats who presented at age four with developmental delay, dysarthria, and seizures before dying at age 6. The boy's clinical presentation and neuropathological findings are directly compared to those of his father, who presented with AOHD and 54 repeats. A full autopsy was performed for the JHD case and a brain-only autopsy was performed for the AOHD case. Histochemically- and immunohistochemically-stained slides were prepared from formalin-fixed, paraffin-embedded tissue sections. Both cases had neuropathology corresponding to Vonsattel grade 3. The boy also had cerebellar atrophy with huntingtin-positive inclusions in the cerebellum, findings not present in the father. Autopsies of father and son provide a unique opportunity to compare and contrast the neuropathologic findings of juvenile and adult onset HD while also providing the first immunohistochemical evidence of cerebellar involvement in JHD. Additionally this is the first known report to include findings from peripheral tissue in a case of JHD.

    Ollier, N.

    2002-09-01

    This study concerns the long-term behaviour of high-level waste glasses and more precisely lanthanides and uranium behaviour with weathering. The leaching was performed on glass powder at 90 deg. C in a pseudo-dynamic mode. Two weathering gels were obtained, with different renewal rate and leaching duration. In glass, we demonstrate that U(IV) and U(VI) species coexist. Time-resolved spectroscopy and XPS measurements show that hexavalent uranium is present under uranyl entities and UO 3 type environment. In weathering gels, U(VI) is still present under uranyl form as well as uranyl hydroxide. It means that U behaviour depends on renewal rate, moreover precipitation of crystallized phases like bauranolte BaU 2 O 7 .xH 2 O and uranyl silicate of uranophane type occur. Concerning lanthanides, Eu 3+ was used as a luminescent local probe. Two sites were found in glass and gels. In glass, the sites were attributed to a silicate and a borate one. In gels, the silicate site is conserved whereas the second one is supposed to correspond to an aluminate one. Photoluminescence and Moessbauer measurements show that the rare earth site symmetry increases in gel. This result confirms that order is higher in gels than in glass. The third part of the thesis concerns irradiation effect in glasses. The main result shows some behaviour differences between a 5 oxides borosilicate glass and a more complex one close to the SON68 glass. Presence of mixed alkali (Na, Li and Cs) seems to notably reduce the Na migration. (author)

    Neutrinoless double beta decay is the only process known so far able to test the neutrino intrinsic nature: its experimental observation would imply that the lepton number is violated by two units and prove that neutrinos have a Majorana mass components, being their own anti-particle. While several experiments searching for such a rare decay have been per- formed in the past, a new generation of experiments using different isotopes and techniques have recently released their results or are taking data and will provide new limits, should no signal be observed, in the next few years to come. The present contribution reviews the latest public results on double beta decay searches and gives an overview on the expected sensitivities of the experiments in construction which will be able to set stronger limits in the near future. EXO and KamLAND-Zen experiments are based on the decay of Xe 136 , GERDA and MAJORANA experiments are based on the decay of Ge 76 , and the CUORE experiment is based on the decay of Te 130

  14. The theory of double layers

    International Nuclear Information System (INIS)

    Schamel, H.

    1982-01-01

    Numerical and in some degree laboratory experiments suggest the existence of at least two different kinds of time-independent double layers: a strictly monotonic transition of the electrostatic potential and a transition accompanied by a negative spike at the low potential side (ion acoustic DL). An interpretation of both is presented in terms of analytic BGK modes. The first class of DLs commonly observed in voltage- or beam-driven plasmas needs for its existence beam-type distributions satisfying a Bohm criterion. The potential drop is at least of the order of Tsub(e), and stability arguments favour currents which satisfy the Langmuir condition. The second class found in current-driven plasma simulations is correlated with ion holes. This latter kind of nonlinear wave-solutions is linearly based on the slow ion-acoustic mode and exists due to a vortex-like distortion of the ion distribution in the thermal range. During the growth of an ion hole which is triggered by ion-acoustic fluctuations, the partial reflection of streaming electrons causes different plasma states on both sides of the potential dip and makes the ion hole asymmetric giving rise to an effective potential drop. This implies that the amplitude of this second type of double layers has an upper limit of 1-2 Tsub(e) and presumes a temperature ratio of Tsub(e)/Tsub(i) > or approximately 3 in coincidence with the numerical results.

    Full Text Available In the past ten years, neutrino oscillation experiments have provided the incontrovertible evidence that neutrinos mix and have finite masses. These results represent the strongest demonstration that the electroweak Standard Model is incomplete and that new Physics beyond it must exist. In this scenario, a unique role is played by the Neutrinoless Double Beta Decay searches which can probe lepton number conservation and investigate the Dirac/Majorana nature of the neutrinos and their absolute mass scale (hierarchy problem with unprecedented sensitivity. Today Neutrinoless Double Beta Decay faces a new era where large-scale experiments with a sensitivity approaching the so-called degenerate-hierarchy region are nearly ready to start and where the challenge for the next future is the construction of detectors characterized by a tonne-scale size and an incredibly low background. A number of new proposed projects took up this challenge. These are based either on large expansions of the present experiments or on new ideas to improve the technical performance and/or reduce the background contributions. In this paper, a review of the most relevant ongoing experiments is given. The most relevant parameters contributing to the experimental sensitivity are discussed and a critical comparison of the future projects is proposed.

  18. Le problème du mal dans le Guide des Perplexes et son arrière-plan talmudique

    Costa, José

    2010-12-01

    Full Text Available At first sight, the question of evil is regarded in the Guide for the Perplexed in a paradoxical manner. Thus, in Guide I, 2, Maimonides examines the notions of good and evil as subjective evaluations possessing neither the rigour not the exactness of the notions of true and false. However, the question of evil occupies an essential place in the Guide, as various modern authors have shown. This question is important to Maimonides because he is, in this respect, the heir of the rabbinic tradition and his conception of evil is largely based on an interaction with the Talmudic and Midrašic texts. Therefore, we would like to review thirty-nine rabbinic ‘quotes’ which appear in chapters 8 to 24 in the third part of the Guide and deal with the origin of evil, the meaning of suffering and the evil inclination. Maimonides reappropriates the midrašim that are susceptible of being in agreement with his rationalist positions and also quotes some rabbinic traditions that are too close to mu ͑tazilism, undoubtedly aware of the more profound resemblance that exists between the rabbinic and mu ͑tazilite doctrines of evil and retribution.A primera vista, el problema del mal es abordado en la Guía de Perplejos de manera paradójica. Para Maimónides, las nociones de bien y mal son subjetivas y no resultan ni rigorosas ni exactas, a la inversa de las nociones de verdad y falsedad (Guía I, 2. Sin embargo, el problema del mal es muy importante en la Guía, como lo demostraran varios autores. Maimónides es el heredero de la tradición rabínica y existe en la Guía una interacción entre la filosofia de Maimónides y los textos talmúdicos y midrásicos. Es particularmente el caso de las treinta y nueve citas rabínicas de la Guía II, 8-24, que tratan del origen del mal, del significado del sufrimiento y de la inclinación al mal. Maimónides cita los midrašim que concuerdan con sus posiciones racionalistas y evoca también algunas tradiciones rab

    We have investigated a 25.75-year old leaching experiment to improve our understanding of the mechanisms controlling glass dissolution in geological disposal conditions. A SON68 glass block was leached in slowly renewed synthetic groundwater (at 90 {sup o}C, 100 bar) in contact with some pieces of granite and Ni-Cr-Mo alloy as environmental storage materials. One hundred and sixty-three samplings were carried out over the entire duration of the experiment and were used to calculate the mean thickness of the altered glass (28 ({+-}9) {mu}m) and the glass dissolution rate. After few months, the rate remained very constant at 6 x 10{sup -3} g m{sup -2} d{sup -1} which is about 20 times higher than the residual rate measured in a batch reactor at the same temperature. At the end of the experiment, mainly SEM analyses were performed on the entire glass block. Surprisingly, the glass alteration layer has neither a homogeneous thickness, nor a homogeneous morphology. The location of the sampling valve (at half height of the glass block) seems to divide the glass block into two parts. In the upper half (above the sampling valve), the general morphology of the alteration layer consists in a relatively simple and uniform gel and some secondary phases which are rare-earth phosphates. The mean measured thickness of this alteration layer is 6.7 ({+-}0.3) {mu}m. However, in the lower half of the glass block, the gel is globally larger and frequently contains rounded shapes which are rare-earth phosphates. This section is edged by secondary phases bearing Mg, Na, Zn and Ni. The mean measured thickness is 81.3 ({+-}1.1) {mu}m in the lower half. In this experiment, the flow rate which leads to the hydrodynamic transport of the soluble species must be a key factor for the local glass alteration process. We have also shown that this unexpected behavior is likely due to heterogeneities of the chemistry of the solution. This conclusion is supported by the behavior of Mg. This element

    Full Text Available En el discurso público comúnmente se asume que Chile es un país solidario, un supuesto que se confunde con la idea de una cierta homogeneidad en lo que respecta a valores solidarios y conductas de ayuda en el país. El presente trabajo apunta a cuestionar esta idea de homogeneidad respecto de solidaridad, proponiendo que las conductas solidarias se relacionan con los recursos que las personas poseen, los que a su vez se asocian al lugar que las personas ocupan en la estructura de estratificación social. Tomando los datos de la Encuesta de Solidaridad realizada en 2009 por el Centro de Medición MIDE UC de la Pontificia Universidad Católica de Chile, el trabajo se centra en un tipo de conducta de ayuda particular: las donaciones en dinero. El análisis se focaliza en la influencia de recursos personales como ingreso, educación y pertenencia a redes sobre este tipo de donaciones. Los resultados indican que los individuos con mayores recursos son más proclives a las donaciones, donde el nivel educacional alcanzado juega un papel preponderante.In the public discourse it is commonly assumed that Chile is a solidary country, an assumption that is mixed with the idea of homogeneity in the country as far as helping behavior and solidarity values is concerned. The present paper is aimed at challenging this homogeneity assumption by proposing that helping behavior is associated to personal resources, which at the same time are linked to the position in the social stratification structure. Using data from the Solidarity Survey implemented by the assessment center MIDE UC of the Pontificia Universidad Católica de Chile in 2009, the paper focuses on a specific type of helping behavior: money donations. The analysis centers on the influence of personal resources such as income, education and networks on this kind of donations. Results indicate that individuals with greater resources are more given to donate, whereby the educational level plays a key

    Full Text Available After some nobles and other fighting men surrendered Rochester castle to King John in 1215, John wanted to hang the nobles but refrained from doing so on the advice of one of his military captains. Would hanging the nobles for making war on the king have been lawful? This question about the law of treason has provoked inconclusive debate among historians who have sought to determine whether, in this period, making war against the English king was legally classified as lèse-majesté (crimen laesae majestatis, proditio or infidelitas. This article, however, asks whether the nobles whom John wanted to hang were guilty of traïson, as this vernacular term was used in the History of William Marshal (c. 1230. On this basis, the paper concludes that in all probability, the nobles who held Rochester against the king would not have been condemned as traitors, at least by their aristocratic peers.Cuando en 1215 ciertos nobles y otros combatientes se rindieron y entregaron el castillo de Rochester al rey Juan éste quiso colgarles, pero el consejo de uno de sus nobles le hizo absternerse. ¿Habría sido legítimo condenar a la horca a los que habían guerreado contra el rey? Cuestiones relativas al derecho de traición al intentar determinar si la guerra contra el rey de Inglaterra fue considerada en la época un crimen laesae majestatis, proditio, o infidelitas, según la definición que dan a estos términos las fuentes latinas, han suscitado debates interminables entre los historiadores. Este artículo, por el contrario, se pregunta si los nobles que el rey Juan deseaba colgar eran o no culpables de traición, en el sentido vernáculo del término que es usado en L’histoire de Guillaume le Maréchal (hacia 1230. Sobre esta base, la conclusión del artículo es que los nobles que ocuparon el castillo de Rochester, casi con total seguridad, no habrían sido condenados como traidores, al menos por sus pares.

El mayor impacto que representa el conocimiento de la asociación de SMSL y estos trastornos, es precisamente la posibilidad de su prevención. El personal médico debe conocer que la más eficiente forma de prevenir el SMSL relacionado con los ECM, es la búsqueda activa de lactantes de riesgo al realizar una exhaustiva anamnesis.

    A double Dirac cone is realized at the center of the Brillouin zone of a two-dimensional phononic crystal (PC) consisting of a triangular array of core-shell-structure cylinders in water. The double Dirac cone is induced by the accidental degeneracy of two double-degenerate Bloch states. Using a perturbation method, we demonstrate that the double Dirac cone is composed of two identical and overlapping Dirac cones whose linear slopes can also be accurately predicted from the method. Because the double Dirac cone occurs at a relatively low frequency, a slab of the PC can be mapped onto a slab of zero refractive index material by using a standard retrieval method. Total transmission without phase change and energy tunneling at the double Dirac point frequency are unambiguously demonstrated by two examples. Potential applications can be expected in diverse fields such as acoustic wave manipulations and energy flow control.

    1984-01-01

    Considerable effort has been expended recently in theoretical studies of double beta decay. Much of this work has focussed on the constraints this process places on gauge theories of the weak interaction, in general, and on the neutrino mass matrix, in particular. In addition, interesting nuclear structure questions have arisen in studies of double beta decay matrix elements. After briefly reviewing the theory of double beta decay, some of the progress that has been made in these areas is summarized. 25 references

    We calculate the complete double logarithmic contribution to cross sections for semi-inclusive hadron production in the modified minimal-subtraction (MS-bar) scheme by applying dimensional regularization to the double logarithm approximation. The full double logarithmic contribution to the coefficient functions for inclusive hadron production in e + e - annihilation is obtained in this scheme for the first time. Our result agrees with all fixed order results in the literature, which extend to next-to-next-to-leading order.

    Experimental results are presented which demonstrate the formation of fully three dimensional double layers in a magnetized plasma. The measurements are performed in a magnetized stationary plasma column with radius 1.5 cm. Double layers are produced by introducing an electron beam with radius 0.......4 cm along the magnetic field from one end of the column. The voltage drop across the double layer is found to be determined by the energy of the incoming electron beam. In general we find that the width of the double layer along the external magnetic field is determined by plasma density and beam...

A piston yoke is driven in the linear stroke direction by a piston axially offset crankshaft cam and a cylinder yoke is driven linearly by a cylinder axially offset crankshaft cam that is exactly offset 180 0 from the other cam. A large circular bushing in the compressor housing covers the entire outer cylinder head during linear operation to prevent blow by and to guide the cylinder linearly. The lower portion of the piston and cylinder connecting rods fit into linear guides that are further comprised of low molecular weight gas filled cavities to provide additional air bearing smoothness to the linear motion of the piston and cylinder

    Second branchial cleft anomalies are the most common of this type of neck masses. They can be classified in four types (Bailey/Proctor classification) according to their location. Type II is the most common, and related to vital neck structures such as the carotid artery and jugular vein. Cysts are the most frequent among them. Management consists of surgical excision of the cyst and tract by cervicotomy to avoid recurrence. We present an extremely rare case of a 32-year-old male who presented a sudden appearance of a right lateral neck mass that was identified by an image study as a double branchial cleft cyst. A review of simultaneous branchial cleft cyst in the literature is also made. Copyright © 2009 Elsevier España, S.L. All rights reserved.

  15. The double-diffusive modon

    Science.gov (United States)

    Radko, Timour

    Fully developed two-dimensional salt-finger convection is characterized by the appearance of coherent dipolar eddies which carry relatively fresh and cold fluid upward and salty and warm fluid downward. Such structures are prevalent in the regime in which density stratification is close to neutral and the salt-finger instability is extremely vigorous. The structure and translation velocities of modons are discussed in terms of the asymptotic expansion in which the background density ratio approaches unity. It is argued that the vertical salt flux is driven primarily by double-diffusive modons, which makes it possible to derive explicit expressions for the mixing rates of temperature and salinity as a function of their background gradients. Predictions of the proposed mixing model are successfully tested by direct numerical simulations.

    The vertical double ionization thresholds of small molecules generally lie above the dissociation limits corresponding to formation of two singly charged fragments. This gives the possibility of populating singly charged molecular ions by photoionization in the Franck-Condon region at energies below the lowest dication state, but above the dissociation limit into two singly charged fragment ions. This process can produce a superexcited neutral fragment that autoionizes at large internuclear separation. We study this process in water, where absorption of a photon produces an inner-shell excited state of H2O+ that fragments to H++OH*. The angular distribution of secondary electrons produced by OH* when it autoionizes produces a characteristic asymmetric pattern that reveals the distance, and therefore the time, at which the decay takes place.

    2011-01-01

    Female coalitions are an important part of the social organization of bonobos. The strength of the mother-son relationship is another essential part of this social structure. A bonobo mother is therefore facing a dilemma when a conflict arises between her sons and her female coalition partners. Will she take her coalition partner's side and favour the social organization of the group or support her son in order to defend her offspring? In order to address this issue, we performed an observational study of the captive group at Planckendael (Belgium) and used social grooming and proximity to assess the relationship between individuals. As a case study, we focused on the relationships between Hortense, one of the group's mothers, her 3 sons Redi, Vifijo and Zamba, and her coalition partner Hermien. Surprisingly, we observed that Hortense preferentially supported her female coalition partner. For Hortense's social status in the group, it may be more important to maintain the strong relationship with her higher-ranking female coalition partner than to support her sons. Copyright © 2012 S.

    The impact of the sex of a deceased child on maternal suicide has not been studied. We examined whether the death of a child, especially a son, increased the risk of suicide among parous Taiwanese women. This matched case-control study was done within a cohort of 1 292 462 Taiwanese women who experienced a first and singleton childbirth between 1 January 1978 and 31 December 1987 and were followed up until 31 December 2008. From the cohort, 2701 suicide cases were identified and 2701 controls were randomly selected. Multiple logistic regression was used to estimate the risk of suicide associated with the death of a child. The adjusted odds ratios (ORs) for suicide among mothers whose son had died were 2.60 (95% CI = 1.18-5.73), 2.58 (1.28-5.20), and 4.20 (0.79-22.45) for death of a son aged younger than 1 year, 1 to 17 years, and 18 years or older. The ORs for suicide associated with the death of a daughter were not statistically significant: the respective adjusted ORs were 1.86 (0.82-4.62), 1.38 (0.54-3.49), and 2.48 (0.40-15.51). The death of a child, especially a son, increased the risk of maternal suicide, which supports the notion that preference for a son is firmly rooted in traditional Chinese culture.

  20. Double layers and circuits in astrophysics

    International Nuclear Information System (INIS)

    Alfven, H.

    1986-05-01

    As the rate of energy release in a double layer with voltage DeltaV is P corresponding to IDeltaV, a double layer must be treated part of a circuit which delivers the current I. As neither double layer nor circuit can be derived from magnetofluid models of a plasma, such models are useless for treating energy transfer by menas of double layers. They must be replaced by particle models and circuit theory. A simple circuit is suggested which is applied to the energizing of auroroal particles, to solar flares, and to intergalactic double radio sources. Application to the heliospheric current systems leads to the prediction of two double layers on the sun's axis which may give radiations detectable from earth. Double layers in space should be classified as a new type of celestial object (one example is the double radio sources). It is tentatively suggested in X-ray and gamma-ray bursts may be due to exploding double layers (although annihilation is an alternative energy source). A study of how a number of the most used textbooks in astrophysics treat important concepts like double layers, critical velocity, pinch effects and circuits is made. It is found that students using these textbooks remain essentially ignorant of even the existence of these, in spite of the fact that some of them have been well known for half a centry (e.g., double layers, Langmuir, 1929: pinch effect, Bennet, 1934). The conclusion is that astrophysics is too important to be left in the hands of the astrophysicist. Earth bound and space telescope data must be treated by scientists who are familiar with laboratory and magnetospheric physics and circuit theory, and of course with modern plasma theory. At least by volume the universe consists to more than 99 percent of plasma, and electromagnetic forces are 10/sup39/ time stronger than gravitation

    2014-06-01

    In an article somewhat ironically entitled "Disambiguating Clinical Intentions," Lynn Jansen promotes an idea that should be bewildering to anyone familiar with the literature on the intention/foresight distinction. According to Jansen, "intention" has two commonsense meanings, one of which is equivalent to "foresight." Consequently, questions about intention are "infected" with ambiguity-people cannot tell what they mean and do not know how to answer them. This hypothesis is unsupported by evidence, but Jansen states it as if it were accepted fact. In this reply, we make explicit the multiple misrepresentations she has employed to make her hypothesis seem plausible. We also point out the ways in which it defies common sense. In particular, Jansen applies her thesis only to recent empirical research on the intentions of doctors, totally ignoring the widespread confusion that her assertion would imply in everyday life, in law, and indeed in religious and philosophical writings concerning the intention/foresight distinction and the Principle of Double Effect. © The Author 2014.

  3. Measurement uncertainty in single, double and triple isotope dilution mass spectrometry.

    2012-02-15

    Triple IDMS has been applied for the first time to the quantification of element concentrations. It has been compared with single and double IDMS obtained on the same sample set in order to evaluate the advantages and disadvantages of triple IDMS over single and double IDMS as an analytical reference procedure. The measurement results of single, double and triple IDMS are indistinguishable, considering rounding due to the individual measurement uncertainties. As expected, the relative expanded uncertainties (k = 2) achieved with double IDMS (0.08%) are dramatically smaller than those obtained with single IDMS (1.4%). Triple IDMS yields the smallest relative expanded uncertainties (k = 2, 0.077%) unfortunately at the expense of a much higher workload. Nevertheless triple IDMS has the huge advantage that the isotope ratio of the spike does not need to be determined. Elements with high memory effects, highly enriched spikes or highest metrological requirements may be typical applications for triple IDMS. Copyright © 2011 John Wiley & Sons, Ltd.

  4. A double-mutant collection targeting MAP kinase related genes in Arabidopsis for studying genetic interactions.

    Science.gov (United States)

    Su, Shih-Heng; Krysan, Patrick J

    2016-12-01

    Mitogen-activated protein kinase cascades are conserved in all eukaryotes. In Arabidopsis thaliana there are approximately 80 genes encoding MAP kinase kinase kinases (MAP3K), 10 genes encoding MAP kinase kinases (MAP2K), and 20 genes encoding MAP kinases (MAPK). Reverse genetic analysis has failed to reveal abnormal phenotypes for a majority of these genes. One strategy for uncovering gene function when single-mutant lines do not produce an informative phenotype is to perform a systematic genetic interaction screen whereby double-mutants are created from a large library of single-mutant lines. Here we describe a new collection of 275 double-mutant lines derived from a library of single-mutants targeting genes related to MAP kinase signaling. To facilitate this study, we developed a high-throughput double-mutant generating pipeline using a system for growing Arabidopsis seedlings in 96-well plates. A quantitative root growth assay was used to screen for evidence of genetic interactions in this double-mutant collection. Our screen revealed four genetic interactions, all of which caused synthetic enhancement of the root growth defects observed in a MAP kinase 4 (MPK4) single-mutant line. Seeds for this double-mutant collection are publicly available through the Arabidopsis Biological Resource Center. Scientists interested in diverse biological processes can now screen this double-mutant collection under a wide range of growth conditions in order to search for additional genetic interactions that may provide new insights into MAP kinase signaling. © 2016 The Authors The Plant Journal © 2016 John Wiley & Sons Ltd.

    2008-01-01

    An order doubling process previously used to obtain eighth-order eigenvalues from the fourth-order Numerov method is applied to the perturbed oscillator in two dimensions. A simple method of obtaining high order finite difference operators is reported and an odd parity boundary condition is found to be effective in facilitating the smooth operation of the order doubling process

    Double LD-Double PSD schedule.employ a symmetric structure and there are a laser and a PSD receiver on each axis. The Double LD-Double PSD is used, and the rectangular coordinate system is set up by use of the relationship of arbitrary two points coordinates, and then the parameter formula is deduced by the knowledge of solid geometry. Using the data acquisition system and the data processing model of laser alignment meter with double laser beam and two detector , basing on the installation parameter of the computer, we can have the state parameter between the two shafts by more complicated calculation and correction. The correcting data of the four under chassis of the adjusted apparatus moving on the level and the vertical plane can be calculated using the computer. This will instruct us to move the apparatus to align the shafts.

  13. Greenhouse effect in double-skin facade

    2007-02-15

    In these last years, a great deal of interest has been devoted to double-skin facades due to the advantages claimed by this technology (in terms of energy saving in the cold season, high-tech image, protection from external noise and wind loads). One of the great characteristics of the double-skin facade is the greenhouse effect. We identify the factors that influence the greenhouse effect. The identified parameters are solar radiation level, orientation and shading devices use, opaque wall/window proportion of the interior facade, wind speed, colour of shading devices and of interior facade, depth of the cavity of the double-skin, glazing type in the interior facade and openings in the double-skin. We analyze the impact of these parameters on the mean air temperature evolution in the cavity. After that analyse, the article answers the question: is greenhouse effect favourable? The answer is moderate according to the double-skin orientation. (author)

  14. Double-trace deformations of conformal correlations

    Giombi, Simone; Kirilin, Vladimir; Perlmutter, Eric

    2018-02-01

    Large N conformal field theories often admit unitary renormalization group flows triggered by double-trace deformations. We compute the change in scalar four-point functions under double-trace flow, to leading order in 1/ N. This has a simple dual in AdS, where the flow is implemented by a change of boundary conditions, and provides a physical interpretation of single-valued conformal partial waves. We extract the change in the conformal dimensions and three-point coefficients of infinite families of double-trace composite operators. Some of these quantities are found to be sign-definite under double-trace flow. As an application, we derive anomalous dimensions of spinning double-trace operators comprised of non-singlet constituents in the O( N) vector model.

    2013-01-01

    We present time-resolved measurements that demonstrate that large amplitude electrostatic instabilities appear in pulsed, expanding helicon plasmas at the same time as particularly strong double layers appear in the expansion region. A significant cross-correlation between the electrostatic fluctuations and fluctuations in the number of ions accelerated by the double layer electric field is observed. No correlation is observed between the electrostatic fluctuations and ions that have not passed through the double layer. These measurements confirm that the simultaneous appearance of the electrostatic fluctuations and the double layer is not simple coincidence. In fact, the accelerated ion population is responsible for the growth of the instability. The double layer strength, and therefore, the velocity of the accelerated ions, is limited by the appearance of the electrostatic instability

    Description of an experiment that was conducted, comparing LED lamps and SON-T (high pressure sodium) lamps. In climate rooms with LED (96% red sodium lamps) or SON-T lamps (without daylight), chrysanthemums were cultivated at two light intensities. Although the air temperature was the same in both treatments, the leaf temperature was clearly higher in the case of SON-T as a result of heat radiation. In the case of LED a more round leaves were observed. Plants cultivated under SON-T light developed closed crops much quicker and required a shorter reaction time (10 to 14 days at high and low light intensity). Yet, the harvest weight of the branches was the same. The net leaf photosynthesis was lower in chrysanthemums cultivated under LED lighting compared to plants cultivated under SON-T lighting. This is probably due to long-term cultivation under a spectrum of almost exclusively red light. The differences between SON-T and LED with regard to light color and heat radiation have significant consequences for growth and development. [Dutch] Een experiment is uitgevoerd om LED lampen en SON-T (hogedruk natriumlampen) lampen te vergelijken. In klimaatkamers met LED (96% rood en 4% blauw) of SON-T lampen (zonder daglichttoetreding) werden chrysanten geteeld bij 2 lichtintensiteiten. Hoewel de luchttemperatuur identiek was bij beide behandelingen was de bladtemperatuur duidelijk hoger bij SON-T als gevolg van warmtestraling. Onder LED belichting werd meer 'bol blad' waargenomen. Planten geteeld onder SON-T belichting ontwikkelden sneller een gesloten gewas en hadden een kortere reactietijd (10 tot 14 dagen bij hoge en lage lichtintensiteit). Maar het oogstgewicht van de takken was gelijk. De netto actuele bladfotosynthese was lager bij chrysanten geteeld onder LED belichting vergeleken met planten geteeld onder SON-T belichting. Dit is waarschijnlijk toe te schrijven aan langdurige teelt onder een spectrum met vrijwel alleen rood licht. De verschillen tussen SON

    Full Text Available Le seuil,abordé en tant que sujet représenté, est ici le moyen d’envisager la question  de la limite et de son dépassement dans le territoire de l’œuvre peinte, de l’installation et de la performance. La fresque de Masaccio, intitulée « Adam et Ève chassés du Paradis », réalisée vers 1425, constitue une étape décisive dans le traitement de l’espace de représentation. La suggestion d’une  profondeur, mais également, d’une épaisseur, apparaît, faisant basculer la peinture vers le naturalisme. Ainsi, au réalisme intellectuel du Moyen Age, se substitue un nouveau mode de figuration. L’artiste de la Renaissance quitte donc un territoire artistique pour explorer et poser les bases d’un art inédit. Dès lors, la toile, telle une zone de friction, se place et agit dans l’interstice séparant l’espace réel et l’espace représenté. La vision du spectateur, face au tableau, franchit ainsi le barrage de l’œuvre pour coloniser une fable topique amenée par l’illusion de la profondeur. La peinture est également le lieu où l’artiste révèle au spectateur, par le biais de stratagèmes plastiques, ses conditions de réalisation. A partir de là, une rupture s’opère entre la représentation et le fait de présenter. Art et vie s’interpénètrent alors, dans des installations ou des performances, offrant au spectateur un lieu milieu, dans lequel il est amené à s’affranchir de ces modèles. L’oeuvre est donc un seuil qu’il faut «traverser pour apprendre la solitude. » (Serres. Elle vibre d’instabilité et cristallise l’état singulier du changement. Enfin, elle conduit inéluctablement vers un devenir autre.The threshold as theme of representation is in this article used as a way to question the limit and its crossing in the territory of the painted work, of the installation and the performance.

  18. Double-disc gate valve

    International Nuclear Information System (INIS)

    Wheatley, S.J.

    1979-01-01

    The invention relates to an improvement in a conventional double-disc gate valve having a vertically movable gate assembly including a wedge, spreaders slidably engaged therewith, a valve disc carried by the spreaders. When the gate assembly is lowered to a selected point in the valve casing, the valve discs are moved transversely outward to close inlet and outlet ports in the casing. The valve includes hold-down means for guiding the disc-and-spreader assemblies as they are moved transversely outward and inward. If such valves are operated at relatively high differential pressures, they sometimes jam during opening. Such jamming has been a problem for many years in gate valves used in gaseous diffusion plants for the separation of uranium isotopes. The invention is based on the finding that the above-mentioned jamming results when the outlet disc tilts about its horizontal axis in a certain way during opening of the valve. In accordance with the invention, tilting of the outlet disc is maintained at a tolerable value by providing the disc with a rigid downwardly extending member and by providing the casing with a stop for limiting inward arcuate movement of the member to a preselected value during opening of the valve

    Complex hydrides are under consideration for on-board hydrogen storage due to their high hydrogen density. However, up to now conventional borohydrides are either too stable or unstable for applications as in PEM fuel cells (60-120 C). Recently, double-cation borohydride systems have attracted great interest. The desorption temperature of the borohydrides decreases with increasing electronegativity of the cation. Consequently, it is possible to tailor a feasible on-board hydrogen storage material by the combination of appropriate cations. The stability was found to be intermediate between the single-cation borohydride systems. Two combinations were sucessfully synthesised by metathesis reaction via high energy ball milling. Al-Li-borohydride shows desorption at about 70 C combined with a very high hydrogen density (17.2 wt.%) and the Na-Al-borohydride (14.2 wt.%) decomposes around 90 C. Both desorption temperatures are in the target range for applications. The decomposition pathways were observed by in-situ-Raman spectroscopy, DSC (Differential Scanning Calorimetry), TG (Thermogravimetry) and thermal desorption measurements.

    2014-03-01

    This study explored the experience of parents living with, and caring for, an adult son or daughter with schizophrenia. There is increasing emphasis on the involvement of carers and users in the care for people with schizophrenia. 'A Vision for Change' highlights the need for a partnership approach and emphasizes that carers are an integral part in the planning and delivery of mental health services. In order to meet such requests, it was necessary to explore the meaning of caregiving for Irish families. A descriptive qualitative design was used to enable parents to describe their experiences. Semi-structured, in-depth interviews with a convenience sample of six parents in Ireland were carried out in 2007. The study encompassed four major themes: psychological tsunami, caring activities, coping with enduring illness and an uncertain pathway. Parents reported severe psychological distress when their son or daughter was diagnosed with schizophrenia. Their deep sense of loss was followed by acceptance of the situation. Feelings of love and a sense of responsibility helped to give meaning to their caring role. This study gave a voice to some parents of a son or daughter with schizophrenia. A family-centred approach should be at the core of care planning for this vulnerable population. © 2013 John Wiley & Sons Ltd.

    Latinos suffer a disproportionate burden of human papillomavirus (HPV)-preventable cancers, yet uptake and completion of the HPV vaccine among Latinos is below recommendations. Reasons for low HPV vaccine uptake among Latinos in Utah are unknown. We surveyed Latino parents of HPV vaccine age-eligible adolescents (N=118). Univariable analyses identified sociodemographic characteristics associated with HPV vaccine awareness, interest, and uptake for daughter(s) and/or son(s) using chi-square tests or Fisher's exact tests. More parents who had lived in the USA for 15 years or more had vaccinated their daughter (43.6 vs. 32.5%, p=0.035) compared to those living in the USA for shorter time periods. Parents born in Mexico reported their son had not received the HPV vaccine (74.6 vs. 58.3%, p=0.049) more than those born elsewhere. Parents with Mexican birthplace and ancestry reported not knowing about the HPV vaccine as the main barrier to vaccinating daughters (47.1 vs. 5.9%, p=0.002 for both) and sons (birthplace 38.3 vs. 10.3%, p=0.007; ancestry 37.1 vs. 11.1%, p=0.013) compared to those born or descending elsewhere. Non-acculturated parents with a son were more likely to report not knowing about the HPV vaccine as the main barrier to vaccine receipt (47.6 vs. 12.5%, pLatinos in an understudied region and complement prior research in other regions.

  6. Simulation of plasma double-layer structures

    Borovsky, J.E.; Joyce, G.

    1982-01-01

    Electrostatic plasma double layers are numerically simulated by means of a magnetized 2 1/2-dimensional particle-in-cell method. The investigation of planar double layers indicates that these one-dimensional potential structures are susceptible to periodic disruption by instabilities in the low-potential plasmas. Only a slight increase in the double-layer thickness with an increase in its obliqueness to the magnetic field is observed. Weak magnetization results in the double-layer electric-field alignment of accelerated particles and strong magnetization results in their magnetic-field alignment. The numerial simulations of spatially periodic two-dimensional double layers also exhibit cyclical instability. A morphological invariance in two-dimensional double layers with respect to the degree of magnetization implies that the potential structures scale with Debye lengths rather than with gyroradii. Electron-beam excited electrostatic electron-cyclotron waves and (ion-beam driven) solitary waves are present in the plasmas adjacent to the double layers

    2017-04-01

    Single photon double ionization cross sections are calculated using an R-matrix with pseudostates (RMPS) method which was recently applied by Gorczyca et al. for the double photoionization of helium. With the convergence of these theoretical calculations for the simple case of helium, we extend this methodology to consider the more complex case of oxygen double photoionization. We compare our calculated results with recent measurements at the Advanced Light Source, as well as earlier experimental measurements. Our RMPS results agree well, qualitatively, with the experimental measurements, but there exist outstanding discrepancies to be addressed. This project is supported by NASA APRA award NNX17AD41G.

    Double hard scattering in proton-proton collisions is described in terms of double parton distributions. We derive bounds on these distributions that follow from their interpretation as probability densities, taking into account all possible spin correlations between two partons in an unpolarized proton. These bounds constrain the size of the polarized distributions and can for instance be used to set upper limits on the effects of spin correlations in double hard scattering. We show that the bounds are stable under leading-order DGLAP evolution to higher scales.

    Buffing, Maarten G.A.

    2017-07-15

    Double parton scattering (DPS) describes two colliding hadrons having interactions in the form of two hard processes, each initiated by a separate pair of partons. Just as for single parton scattering, the resummation of soft gluon exchange gives rise to a soft function, which is a necessary ingredient for obtaining rapidity evolution equations. For various regions of phase space, we derive the rapidity evolution and the scale evolution of double transverse momentum dependent parton distribution functions (DTMDs) as well as of the p{sub T}-resummed cross section for double Drell-Yan like processes. This contributes to a framework that can be used for phenomenological DPS studies including resummation.

Patterns and mechanisms of Holocene climate change in arid Central Asia are, however, only partially understood. Multi-proxy data combining diatom, ostracod, sedimentological, geochemical and stable isotope analyses from a ca. 6000-year-old lake sediment core from Son Kol (Central Kyrgyzstan) show distinct and repeated changes in species assemblages. Diatom- and ostracod-inferred conductivity shifts between meso-euhaline and freshwater conditions suggest water balance and regime shifts. Organism-derived data are corroborated by stable isotope, mineralogical and geochemical records, underlining that Son Kol was affected by strong lake level fluctuations of several meters. The δ13Ccarb/δ18Ocarb correlation shows repeated switchovers from a closed to an open lake system. From 6000 to 3800 and 3250 to 1950 cal. yr BP, Son Kol was a closed basin lake with higher conductivities, increased nutrient availability and a water level located below the modern outflow. Son Kol became again a hydrologically open lake at 3800 and 1950 cal. yr BP. Comparisons to other local and regional paleoclimate records indicate that these regime shifts were largely controlled by changing intensity and position of the Westerlies and the Siberian Anticyclone that triggered changes in the amount of winter precipitation. A strong influence of the Westerlies ca. 5000-4400, 3800-3250 and since 1950 cal. yr BP enhanced the amount of precipitation during spring, autumn and winter, whereas cold and dry winters prevailed during phases with a strong Siberian Anticyclone and southward shifted Westerlies at ca. 6000-5000, 4400-3800 and 3250-1950 cal. yr BP. Similarities between variations in winter precipitation at Son Kol and records of the predominant NAO-mode further suggest a teleconnection between wet (dry) winter climate in Central Asia and a positive (negative) NAO

    The review of modern experiments on search and studying of double beta decay processes is done. Results of the most sensitive current experiments are discussed. The main attention is paid to EXO-200, KamLAND-Zen, GERDA-I and CUORE-0 experiments. Modern values of T{sub 1/2}(2ν) and best present limits on neutrinoless double beta decay and double beta decay with Majoron emission are presented. Conservative limits on effective mass of a Majorana neutrino (〈m{sub ν}〉 < 0.46 eV) and a coupling constant of Majoron to neutrino (〈g{sub ee}〉 < 1.3 · 10{sup −5}) are obtained. Prospects of search for neutrinoless double beta decay in new experiments with sensitivity to 〈m{sub ν}〉 at the level of ∼ 0.01-0.1 eV are discussed.

  3. Frequency Doubling Broadband Light in Multiple Crystals

    Alford, William J.; Smith, Arlee V.

    2000-01-01

    The authors compare frequency doubling of broadband light in a single nonlinear crystal with doubling in five crystals with intercrystal temporal walk off compensation, and with doubling in five crystals adjusted for offset phase matching frequencies. Using a plane-wave, dispersive numerical model of frequency doubling they study the bandwidth of the second harmonic and the conversion efficiency as functions of crystal length and fundamental irradiance. For low irradiance the offset phase matching arrangement has lower efficiency than a single crystal of the same total length but gives a broader second harmonic bandwidth. The walk off compensated arrangement gives both higher conversion efficiency and broader bandwidth than a single crystal. At high irradiance, both multicrystal arrangements improve on the single crystal efficiency while maintaining broad bandwidth

  4. The topology of Double Field Theory

    We describe the doubled space of Double Field Theory as a group manifold G with an arbitrary generalized metric. Local information from the latter is not relevant to our discussion and so G only captures the topology of the doubled space. Strong Constraint solutions are maximal isotropic submanifold M in G. We construct them and their Generalized Geometry in Double Field Theory on Group Manifolds. In general, G admits different physical subspace M which are Poisson-Lie T-dual to each other. By studying two examples, we reproduce the topology changes induced by T-duality with non-trivial H-flux which were discussed by Bouwknegt, Evslin and Mathai [1].

  5. Preparation of uranium ingots from double fluorides

    1967-05-01

    A simple method has been developed for the preparation of uranium double fluorides and has given a new impetus to the study of the reduction of these compounds with a view to obtaining very pure uranium ingots. This reduction can be carried out using calcium or magnesium as the reducing agent, this latter metal being very interesting from the practical point of view. A comparative study of the heat balances of the reduction processes for the double fluorides and for uranium tetrafluoride has shown that reduction of the double fluorides is possible. The exact experimental conditions for these reductions have been determined. Our study has shown in particular that the reduction of the double salt UF 4 , CaF 2 by magnesium leads to the production of small (20 to 500 g) samples of high-purity uranium with a yield of 99 per cent.

    Investigations of double layer dynamics are performed in a Q-machine plasma by applying a positive step potential to a cold end-plate collector. The double layer created at the grounded plasma source just after the pulse is applied propagates towards the collector with the plasma flow speed. Large oscillations occur in the plasma current which is related to a recurring formation and propagation of the double layer. The current is limited during the propagation by a growing negative potential dip formed on the low-potential tail. Similar phenomena appear on the low-potential tail of the stationary double layer formed by applying a potential difference between two plasma sources. (author)

    Double marginalization occurs in vertical industries when both the upstream and downstream firms have monopoly power. Each firm reduces output from the competitive level to the monopoly level,creating two deadweight losses. This market myopia creates a "vertical externality" that vertical integration would internalize.

    A comprehensive numerical study of ion acoustic double layers has been performed for both periodic as well as for nonperiodic systems by means of one-dimensional particle simulations. For a nonperiodic system, an external battery and a resistance are used to model the magnetospheric convection potential and the ionospheric Pedersen resistance. It is found that the number of double layers and the associated potential buildup across the system increases with the system length

    Following up on the recent work of Cachazo, He and Yuan \\cite{arXiv:1503.04816 [hep-th]}, we derive the double soft graviton theorem in perturbative gravity. We show that the double soft theorem derived using CHY formula precisely matches with the perturbative computation involving Feynman diagrams. In particular, we find how certain delicate limits of Feynman diagrams play an important role in obtaining this equivalence.

  15. THE EFFICIENCY OF TENNIS DOUBLES SCORING SYSTEMS

    2010-09-01

    Full Text Available In this paper a family of scoring systems for tennis doubles for testing the hypothesis that pair A is better than pair B versus the alternative hypothesis that pair B is better than A, is established. This family or benchmark of scoring systems can be used as a benchmark against which the efficiency of any doubles scoring system can be assessed. Thus, the formula for the efficiency of any doubles scoring system is derived. As in tennis singles, one scoring system based on the play-the-loser structure is shown to be more efficient than the benchmark systems. An expression for the relative efficiency of two doubles scoring systems is derived. Thus, the relative efficiency of the various scoring systems presently used in doubles can be assessed. The methods of this paper can be extended to a match between two teams of 2, 4, 8, …doubles pairs, so that it is possible to establish a measure for the relative efficiency of the various systems used for tennis contests between teams of players.

    2013-09-01

    While alcohol consumption and heavy episodic (binge) drinking are well-established predictors of male-to-male alcohol-related aggression (MMARA), the role of the father-son relationship in MMARA has yet to be explored. This study therefore examined whether fathering by the biological father rather than another father figure, negative fathering, and gender role modeled by the father figure were significant predictors of involvement in MMARA, once drinking frequency and quantity and heavy episodic drinking were controlled for. A total of 121 university students aged 18 to 25 years (M = 20.63, SD = 1.77 years) voluntarily completed the online questionnaire. The only significant predictors of perpetration of MMARA were a more abusive paternal relationship and drinking quantity (number of standard drinks usually consumed when drinking). Negative father-son relationships may play a role in fostering young men's perpetration of MMARA in the barroom context. Copyright © 2013 by the Research Society on Alcoholism.

  20. Parental choice: what parents want in a son-in-law and a daughter-in-law across 67 pre-industrial societies.

    Parents are influential over mate choice, and in most human societies they choose spouses for their offspring according to their own preferences. However, surprising little is known about the qualities which make a woman desirable as a daughter-in-law and a man desirable as a son-in-law. Using evidence from 67 societies such traits are identified and three hypotheses are tested: first, the hypothesis is tested that parents desire in an in-law qualities which are beneficial to them and their kin. Second, it is hypothesized that such preferences are contingent upon the sex of the in-law, as traits are weighted differently in a daughter-in-law and in a son-in-law. The third hypothesis tested is that parental preferences vary according to the subsistence type of a given society, as traits are valued differently in agropastoral societies and foraging societies. The evidence presented here provides support for all three hypotheses.

    2017-01-01

    The French simulated nuclear waste SON68 glass was altered in the presence of water vapor at 175 °C and 98% of relative humidity under several atmospheres (NH_3, H_2S, CO_2 and argon). The objectives were to study the role of pH on hydration kinetics and secondary phases formation. The hydration was followed by infrared spectroscopy and the nature and extent of alteration products were determined by characterizing the reacted glass surface with scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS), μ-Raman spectroscopy and X-ray diffraction (XRD). The glass hydration/alteration rate clearly increased with increasing pH, that is controlled by the gas atmosphere, as the following: NH_3 > Ar > CO_2 > H_2S. This can directly be linked to the secondary phases precipitated on the glass surface. Hence, the major alteration products observed at high pH (under NH_3 and Ar) are analcime and Ca-silicates hydrates (CSH) while at low pH (under CO_2 and H_2S) only a hydrated gel layer was identified. - Highlights: • The vapor hydration study of the SON68 glass under geological conditions. • The secondary phases formation in the alteration of SON68 glass. • The pH effect on the alteration kinetics of glass.

    The double patterning (DPT) process is foreseen by the industry to be the main solution for the 32 nm technology node and even beyond. Meanwhile process compatibility has to be maintained and the performance of overlay metrology has to improve. To achieve this for Image Based Overlay (IBO), usually the optics of overlay tools are improved. It was also demonstrated that these requirements are achievable with a Diffraction Based Overlay (DBO) technique named SCOLTM [1]. In addition, we believe that overlay measurements with respect to a reference grid are required to achieve the required overlay control [2]. This induces at least a three-fold increase in the number of measurements (2 for double patterned layers to the reference grid and 1 between the double patterned layers). The requirements of process compatibility, enhanced performance and large number of measurements make the choice of overlay metrology for DPT very challenging. In this work we use different flavors of the standard overlay metrology technique (IBO) as well as the new technique (SCOL) to address these three requirements. The compatibility of the corresponding overlay targets with double patterning processes (Litho-Etch-Litho-Etch (LELE); Litho-Freeze-Litho-Etch (LFLE), Spacer defined) is tested. The process impact on different target types is discussed (CD bias LELE, Contrast for LFLE). We compare the standard imaging overlay metrology with non-standard imaging techniques dedicated to double patterning processes (multilayer imaging targets allowing one overlay target instead of three, very small imaging targets). In addition to standard designs already discussed [1], we investigate SCOL target designs specific to double patterning processes. The feedback to the scanner is determined using the different techniques. The final overlay results obtained are compared accordingly. We conclude with the pros and cons of each technique and suggest the optimal metrology strategy for overlay control in double

    2017-08-03

    The 2016 revision of the World Health Organization (WHO) classification for lymphoma has included a new category of lymphoma, separate from diffuse large B-cell lymphoma, termed high-grade B-cell lymphoma with translocations involving myc and bcl-2 or bcl-6 . These lymphomas, which occur in hit lymphomas (or triple-hit lymphomas if all 3 rearrangements are present). It is important to differentiate these lymphomas from the larger group of double-expressor lymphomas, which have increased expression of MYC and BCL-2 and/or BCL-6 by immunohistochemistry, by using variable cutoff percentages to define positivity. Patients with double-hit lymphomas have a poor prognosis when treated with standard chemoimmunotherapy and have increased risk of central nervous system involvement and progression. Double-hit lymphomas may arise as a consequence of the transformation of the underlying indolent lymphoma. There are no published prospective trials in double-hit lymphoma, however retrospective studies strongly suggest that aggressive induction regimens may confer a superior outcome. In this article, I review my approach to the evaluation and treatment of double-hit lymphoma, with an eye toward future clinical trials incorporating rational targeted agents into the therapeutic armamentarium. © 2017 by The American Society of Hematology.

  7. The doubling of stellar black hole nuclei

    Kazandjian, Mher V.; Touma, J. R.

    2013-04-01

    It is strongly believed that Andromeda's double nucleus signals a disc of stars revolving around its central supermassive black hole on eccentric Keplerian orbits with nearly aligned apsides. A self-consistent stellar dynamical origin for such apparently long-lived alignment has so far been lacking, with indications that cluster self-gravity is capable of sustaining such lopsided configurations if and when stimulated by external perturbations. Here, we present results of N-body simulations which show unstable counter-rotating stellar clusters around supermassive black holes saturating into uniformly precessing lopsided nuclei. The double nucleus in our featured experiment decomposes naturally into a thick eccentric disc of apo-apse aligned stars which is embedded in a lighter triaxial cluster. The eccentric disc reproduces key features of Keplerian disc models of Andromeda's double nucleus; the triaxial cluster has a distinctive kinematic signature which is evident in Hubble Space Telescope observations of Andromeda's double nucleus, and has been difficult to reproduce with Keplerian discs alone. Our simulations demonstrate how the combination of an eccentric disc and a triaxial cluster arises naturally when a star cluster accreted over a preexisting and counter-rotating disc of stars drives disc and cluster into a mutually destabilizing dance. Such accretion events are inherent to standard galaxy formation scenarios. They are here shown to double stellar black hole nuclei as they feed them.

Some features of the concept that have today become obvious can already come into sight in this first approach. The work devotes itself then to point out the implications (and, most of all, the consequences involved in openly ascribing responsibility to the Modern Age and to the rise of industrial civilization. One of these main consequences is perhaps to have to deal with a number of theoretical topics in a necessary connexion with another axial topic of modern thought, namely, identity. Besides, the essay points also to a number of topics, such as the problem of the alleged collective responsibilities and also that of evil, just to quote two of them, whose magnitude may serve as an indicator to the relevance of the concept of responsibility in contemporary thought.

    International Nuclear Information System (INIS)

    Liu, Fei; Jin, Jie

    2015-01-01

    Fano resonances are investigated in nanorods with symmetric lengths and side-by-side assembly. Single Fano resonance can be obtained by a nanorod dimer, and double Fano resonances are shown in nanorod trimers with side-by-side assembly. With transverse plasmon excitation, Fano resonances are caused by the destructive interference between a bright superradiant mode and dark subradiant modes. The bright mode originates from the electric plasmon resonance, and the dark modes originate from the magnetic resonances induced by near-field inter-rod coupling. Double Fano resonances result from double dark modes at different wavelengths, which are induced and tuned by the asymmetric gaps between the adjacent nanorods. Fano resonances show a high figure of merit and large light extinction in the periodic array of assembled nanorods, which can potentially be used in multiwavelength sensing in the visible and near-infrared regions.

  12. Stochastic cooling with a double rf system

    International Nuclear Information System (INIS)

    Wei, Jie.

    1992-01-01

    Stochastic cooling for a bunched beam of hadrons stored in an accelerator with a double rf system of two different frequencies has been investigated. The double rf system broadens the spread in synchrotron-oscillation frequency of the particles when they mostly oscillate near the center of the rf bucket. Compared with the ease of a single rf system, the reduction rates of the bunch dimensions are significantly increased. When the rf voltage is raised, the reduction rate, instead of decreasing linearly, now is independent of the ratio of the bunch area to the bucket area. On the other hand, the spread in synchrotron-oscillation frequency becomes small with the double rf system, if the longitudinal oscillation amplitudes of the particles are comparable to the dimension of the rf bucket. Consequently, stochastic cooling is less effective when the bunch area is close to the bucket area

    At the request of the Department of Energy (DOE), a formal plan for the emergency transfer of waste from a leaking double shell tank to a designated receiver tank has been developed. This plan is in response to the priority 2 safety issue ''Response to a leaking double-shell tank'' in the DOE Report to Congress, 1991. The plan includes the tanks in four of the east tank farms and one of the west farms. The background information and supporting calculations used for the creation of the emergency plan are discussed in this document. The scope of this document is all of the double shell tanks in the AN, AP, AW, AY, and SY farms. The transfer lines, flush pits, and valve pits involved in the transfer of waste between these farms are also included in the scope. Due to the storage of high heat waste, AZ farm is excluded at this time

    as "double Holliday junction dissolution." This reaction requires the cooperative action of a so-called "dissolvasome" comprising a Holliday junction branch migration enzyme (Sgs1/BLM RecQ helicase) and a type IA topoisomerase (Top3/TopoIIIα) in complex with its OB (oligonucleotide/oligosaccharide binding......Double Holliday junctions (dHJS) are important intermediates of homologous recombination. The separate junctions can each be cleaved by DNA structure-selective endonucleases known as Holliday junction resolvases. Alternatively, double Holliday junctions can be processed by a reaction known......) fold containing accessory factor (Rmi1). This review details our current knowledge of the dissolution process and the players involved in catalyzing this mechanistically complex means of completing homologous recombination reactions....

  15. CAD/CAM for Double Woven Fabric

    Full Text Available To bond the two layers in double fabrics, various types of stitching can be distinguished such as self-stitching, double stitching, center warp stitching, center weft stitching, and so on. In this article, a mathematic model based on a software program has been developed to automatically generate a double fabric stitched by additional warp called center warp. Each layer has been represented in a 2D binary matrix, and a new matrix called warps order matrix has been defined to demonstrate the modality of position of the center warps in relating to the top and bottom fabrics’ warps. After insertion of all warps in the extended weave matrix, the lifter conditions has been discussed and the stitching points have been determined.

  16. Experiments on ion acoustic typed double layers

    The formation of small amplitude double layers with potential drops the order of the electron temperature, was examined experimentally by pulsing a grid and thereby changing the electron drift across the target chamber of a triple plasma device. The rarefactive part of a long wavelength, low frequency ion wave grew in amplitude due to the presence of slowly drifting electrons. The corresponding current limitation led to the formation of the double layers. Depending on the plasma conditions, the asymmetric double layers either transform into a weak monotonic layer, a propagating shock, or a series of rarefactive solitary pulses. The rarefactive pulses propagate with Mach number less than one and resemble solitary plasma holes with density cavities in both the electron and the ion density profiles

    The double emittance exchange (EEX) beamline is suggested to overcome the large horizontal emittance and transverse jitter issues associated with the single EEX beamline while preserving its powerful phase-space manipulation capability. However, the double EEX beamline also has potential limitations due to coherent synchrotron radiation (CSR) and transverse jitter. The former limitation arises because double EEX uses twice as many bending magnets as single EEX which means stronger CSR effects degrading the beam quality. The latter limitation arises because a longitudinal jitter in front of the first EEX beamline is converted into a transverse jitter in the middle section (between the EEX beamlines) which can cause beam loss or beam degradation. In this paper, we numerically explore the effects of these two limitations on the emittance and beam transport.

    Full Text Available Neste artigo, propomos um sistema para determinação de harmonias espectrais extraídas de sons concretos a partir da utilização do algoritmo de contraponto dissonante, desenvolvido por James Tenney. Com base nesse algoritmo, definimos um sistema composicional, descrevemos sua implementação como aplicativo computacional e o utilizamos no planejamento composicional de duas obras originais: o primeiro movimento de um quarteto de clarinetes e um quinteto de metais.
