La concentration en radon est dosee de facon continue a l'aide d'un nouvel appareil dont la sensibilite atteint 0,2.10{sup -11} Ci m{sup -3} soit le cinquantieme de la teneur moyenne de l'air au voisinage du sol, cet appareil permet de montrer que l'equilibre radioactif entre le radon et ses descendants a vie courte est realise pendant les periodes ou l'atmosphere est stable. Les observations dans l'air entre 0 et 100 metres au-dessus du sol indiquent que le radon et son depot actif sont de precieux traceurs marquant la stabilite de l'atmosphere. En periode d'inversion de temperature, la nuit en general, le radon s'accumule dans les 30 premiers metres de la couche d'air, puis est chasse avec te lever du soleil et passe au niveau de 100 metres a 9 heures du matin.

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

    This work is concerned with the study of acid-base reactions and of complex formation in ethanolamine and its mixtures with water. The ionic product of the solvent has been determined by an electro-chemical study of the H{sup +}/H{sub 2} system. The reduction curves for ethanolamine-water mixtures, for different acidities, have made it possible to follow the variations in the size of the pH domain as a function of the composition of the solvent. The form of this variation has been explained on the basis of the dielectric constant and the solvation of the proton by the ethanolamine. In the second part, the electrochemical systems of mercury have been studied by anodic polarography. In order to establish a parallel between the acid-base reactions and complex formation reactions, we have studied the stability of Hg (CN){sub 2} in water-ethanolamine mixtures. It has been possible to deduce the law for the variation of pK{sub c} with solvent composition. The representative graph of this function passes through a minimum for a proportion of about 50 per cent of ethanolamine as in the case of acids. This variation has been explained by the predominating influence of {epsilon} for ethanolamine propositions of over 50 per cent and by that of the solvation of Hg{sup 2+} for proportions of under 50 per cent. (author) [French] Ce travail porte sur l'etude des reactions acides-bases et de formation de complexes dans l'ethanolamine et ses melanges avec l'eau.

Les courbes de reduction des melanges ethanolamine-eau, pour des acidites variables, ont permis de suivre les variations de l'etendue du domaine de pH, en fonction de la composition du solvant. L'allure de cette variation a ete expliquee en faisant intervenir la constante dielectrique et la solvatation du proton par l'ethanolamine.

    Cette recherche a pour but de redéfinir la notion de « parole efficace » dans la Grèce antique, notamment dans le contexte dramatique. Pour ce faire, elle applique les concepts de la pragmatique moderne aux rites langagiers ayant cours dans la Grèce archaïque et jusqu’au 5ème siècle. Il en ressort que chaque énoncé, plutôt que d’être assimilé à une « formule magique », doit être analysé selon trois données fondamentales en regard de l'efficacité de la parole: la part rituelle de la pratique, ...

    Since the eighties, more and more studies were performed about radon and its decay products in houses with one of the aim being the estimation of the dose received by their inhabitants. Then, the principal objective of this work is to describe the behaviour of radon and its decay products within a dwelling. In the first part to the report, a few definitions are given and data from literature give an idea of indoor radon and radon decay products activities and/or size distribution. Aspects of dosimetry are presented too. In the second part of the work, a mathematical model, called `PRADDO` of Physic of Radon and radon Decay products in Domestic environment is developed on the basis of the classical model written by Jacobi in 1972. On the one hand, it has to predict radon decay products activities in systems consisting in one or more enclosure(s), from radon activity and from ambient aerosol concentration and size distribution. On the other hand, one part of the model is assigned to study the influence of the entry model parameters variation on the calculated quantities. Then, in the third part of the work, two experimental studies are realised in order to compare measurements to modelization. The first experimentation is a laboratory work, made on the test bench ICARE from IPSN, and the second one consists in describing the basement of an occupied house from Brittany. In the two cases, the comparison between experiments and modelling shows a good agreement if particles are present in the air, but any conclusion is made when is no aerosol in the enclosure.

    Full Text Available L’historiographie grecque a, selon les époques, pour raisons idéologiques, présenté fort différemment les guérillas nationalistes des années 1900 en Macédoine.La campagne déclenchée par les bandes de guérilla nationalistes entre 1904 et 1908 pour gagner de force « le territoire des âmes » de la population macédonienne, a eu plusieurs aspects ; sa dimension de guerre civile, déchirement fratricide des communautés chrétiennes slavophones, a été reconnue à l’époque par les principaux acteurs et par la plupart des observateurs extérieurs. Son traitement dans l’historiographie grecque est très éclairant sur la fonction idéologique que celle-ci a été appelée à remplir depuis un siècle ; cet article présente les quatre étapes que l’on peut distinguer dans ce traitement depuis un siècle, variations liées évidemment au contexte politique balkanique et intérieur grec : 1910-40, 1941-1974, 1974-1992 et depuis 1992.The war engaged by the nationalist guerrilla bands between 1904 and 1908 to obtain by force “the souls territory” of the Macedonian population, had different forms. The civil war aspect, bloody shooting between brothers of Christian slavophones communities, was recognized at the time by the main actors of it ans the foreign observers. Its treatment by the Greek historiography shows a very clear light on the ideological function it has been supposed to assume since one century and over. This paper presents the four moments in this treatment whose variations are related, of course, to the political Greek and Balkan context: 1910-1940, 1941-1974, 1974-1992 and from 1992.

    Full Text Available Cette étude se propose de dégager les caractéristiques du chantier de construction, dans son organisation et dans ses enjeux, en se référant aux évolutions architecturales perceptibles dans le diocèse de Clermont entre la fin du xie siècle et le xiiiesiècle. Le chantier ecclésiastique focalise les préoccupations, depuis les grands chantiers de la Limagne et les édifices d’ampleur, jusqu’aux sanctuaires plus modestes de plaine et de moyenne montagne. La réflexion prend aussi en compte le chantier laïc, ce dernier permettant d’éclairer la diversité des techniques, la position des différents acteurs, et de mesurer l’impact des savoir-faire et des environnements sur la condition sociale des bâtisseurs. D’autres pistes de réflexion connexes viennent aussi jalonner le propos pour élargir le débat en envisageant les niveaux de hiérarchisation et d’appropriation de l’espace bâti, la question de la matérialisation des héritages, ou encore la question de l’individualité de l’ouvrier qualifié.This study proposes to establish the characteristics of building construction, its organization and its consequences, while referring to the perceptible architectural evolutions in the diocese of Clermont from the end of 11th throughout the 13th century. The ecclesiastical building site focuses these concerns, from the large building sites of Limagne and its vast structures to the more modest sanctuaries of smaller mountains. The analysis is also interested in secular construction, as it allows us to clarify the diversity of techniques and the position of various actors, and to measure the impact of technical knowledge and the environment on the social conditions of the builders. We will also widen the debate by considering the following questions: how a constructed space is structured and appropriated; the affirmation of heritages; and the individuality of the skilled worker.Questo studio si propone di stabilire le

He had a tooth abscess one week ago. Chest tomography showed neck and mediastinal air and fluid collections. Antibiothreapy was started and urgent surgical management applied. Neck drainage was performed via transcervical approach. Mediastinal drainage was performed via right thoracotomy. Continue mediastinal washing feasibility was done by drainage tubes. Drainage was ended after nonextra drainage and cultural growthless. Vital signs became stable and control tomography showed complete recovery. He was healthfull at the 6th month’s follow-up.Broad antibiothreapy, surgical management are the main approaches for descending necrotising mediastinitis.

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

    Whereas low contents of metallic additions have only a small influence on the temperature at which magnesium begins to burn in carbon dioxide, an increase in the specific surface area of the samples is likely to reduce it considerably, the self-heating phenomena being then more pronounced. On the other hand, the exact nature of the surrounding atmosphere is a very important factor; thus the temperature at which ignition begins increases with increasing carbon dioxide pressure, decreases very rapidly when the moisture content of this gas increases up to 3000 v.p.m., and decreases regularly when the partial pressure of air or oxygen increases. (authors) [French] Alors que de faibles teneurs en additions metalliques n'ont que peu d'influence sur la temperature d'inflammation du magnesium dans le gaz carbonique, l'augmentation de la surface specifique des echantillons est susceptible de l'abaisser fortement, le phenomene d'autochauffage se trouvant alors accru. D'autre part, la nature exacte de l'atmosphere gazeuse ambiante est un facteur tres important; ainsi la temperature d'inflammation croit avec la pression du gaz carbonique, decroit tres rapidement lorsque sa teneur en humidite augmente jusqu'a 3000 v.p.m., et diminue regulierement lorsque la pression partielle d'air ou d'oxygene augmente.

    The kinetics of the transformation of uranium alloys containing 0.5 - 0.75 - 1.0 - 1.5 and 3 atoms per cent have been studied. The influence of heat treatment before decomposition has been discussed. The study of the transformation characteristics such as kinetics, residual phases, phenomena connected with the coherence between phases, reversibility below the equilibrium temperature, shows the following mechanisms exhibited during the decomposition of the {beta} phase on lowering the temperature: 1 ) eutectoid, 2) bainitic, 3) martensitic. The study of the TTT diagrams of alloys containing decreasing percentages of chromium indicates that the unalloyed uranium transforms without maintaining the coherence above 600 deg. C, where as at lower temperatures the transformation is mainly martensitic. The various alloying elements can be characterised by their influence on the three TTT curves corresponding to the three possible transformation mechanisms. The ability of the uranium alloys to alpha grain refining during isothermal decomposition or ambient temperature quenching is directly connected with the characteristics of the TTT diagrams and especially to the mode of bainitic transformation.

    With the increase of contaminant flux of radionuclides in surface environment (soil, river, aquifer...), there is a need to understand and model the processes that control the distribution of uranium and its daughter products during transport within aquifers. We have used U-series disequilibria as an analogue for the transport of uranium and its daughter products in aquifer to understand such mechanisms. The measurements of uranium ({sup 234}U et {sup 238}U), thorium ({sup 230}Th et {sup 232}Th), {sup 226}Ra and {sup 222}Rn isotopes in the solid and liquid phases of the chalk aquifer in Champagne (East of France) allows us to understand the processes responsible for fractionation within the uranium decay chain. Fractionations are induced by physical and chemical properties of the elements (leaching, adsorption) but also by radioactive properties (recoil effect during {alpha}-decay). For the first time a comprehensive sampling of the solid phase has been performed, allowing quantifying mechanisms responsible for the long term evolution of the aquifer. A non steady state 1D model has been developed which takes into account leaching, adsorption processes as well as radioactive filiation and {alpha}-recoil effect. Retardation coefficients have been calculated for uranium, thorium and radium. The aquifer is characterised by a double porosity, and the contribution of fracture and matrix porosity on the water/rock interaction processes has been estimated. (author)

    Full Text Available This study aimed to comprehend the meaning of suicide for Japanese descendants. This was a qualitative study, based on Grounded Theory, using a structured interview with sixteen questions, digitally recorded. Subjects were ten descendants who were interviewed in 2011. The opinions of the interviewed showed factors of psychological, social and cultural origin involved in suicide, such as: heredity, religion, mental health, personality characteristics and interpersonal relationships, pleasure and pain at work, stigma and consequences of the act on the family. Family without case of suicide showed attitudes of prejudice and judgment, while those with case displayed feelings of pain in their reports. It was concluded that the Japanese rigid culture, personality, interpersonal communication and the way family and work have effects on their behavior are predisposing factors to suicide, as well as the identification of these factors contributes to a better performance of the nurse.

    Full Text Available A 47-year-old male with a history of left colon cancer, status post left colon resection for 12 years, presented with rectal bleeding. Colonoscopic examination revealed an 8 mm sessile polyp in the proximal descending colon. Microscopic examination showed that the surface of this polyp was covered with a layer of normal colonic mucosa with focal surface erosion. In the submucosal layer, an intimate admixture of multiple cystically dilated glands and prominent lymphoid aggregates with germinal centers was seen. The glands were lined by columnar epithelium. Immunohistochemical staining showed the glands were positive for CK20 and CDX2 and negative for CK7, with a low proliferative index, mostly consistent with reactive colonic glands. The patient remained asymptomatic after one-year follow-up. A review of the literature shows very rare descriptions of similar lesions, but none fits exactly this pattern. We would designate this inverted lymphoglandular polyp and present this case to raise the awareness of recognizing this unusual histological entity.

    Full Text Available Faisant suite à l’idée de Paul Mus concernant l’existence d’une « religion cadastrale » constitutive de l’organisation socio-religieuse du « socle asien », nous proposons d’approcher de manière comparative les rituels liés à la prospérité du territoire des populations vivant en marge des pouvoirs étatiques des régions sinisées et indianisées, ce que nous appelons ici les « marges sino-indiennes ». Ces rituels s’organisent autour d’un schéma récurrent dont nous analysons les détails et les variantes. Il s’agit d’une force du lieu, naturelle et sauvage, pacifiée par un ancêtre fondateur, lequel en devient avec ses descendants les sacrificateurs représentant la communauté toute entière. En légitimant l’occupation d’un espace par un groupe et en favorisant sa fertilité, ces rituels sont le lieu de cristallisation de nombreux enjeux imbriqués qui impliquent tout à la fois les sources de la subsistance, la légitimité d’occuper un territoire, mais aussi les formes d’appartenance et l’exercice du pouvoir interne au groupe et dans sa relation avec ses voisins et les centres de pouvoir qui les englobent.Taking Paul Mus’s idea of a “cadastral religion” as part of the socio-religious organisation of the “Asian base” further, we propose approaching rituals linked to the territorial prosperity of groups living on the margins of state power in the Chinese and Indian worlds in a comparative way. These rituals are organised around the recurring schema of a force of place, both natural and wild, which was pacified by a founding ancestor who, along with his descendants, became the sacrificers representing the entire community—a schema the details and variations of which we have analysed. By legitimising the occupation of a space by one group and promoting its fertility, these rituals are where many interlocking stakes are crystallised. These involve the sources of subsistence and the

    BACKGROUND: Although research into the continuity and change of personality traits during a lifespan has been fairly extensive, little research has been conducted on childhood predictors of adult personality. PURPOSE: We aimed to investigate the association between infant socioeconomic status (SES......), and Eysenck personality traits in adulthood. An additional aim was to investigate whether intelligence and education may mediate this association. METHODS: SES of 9125 children in the Copenhagen Perinatal Cohort was recorded at a 1-year examination. A subsample of this cohort, comprising 1182 individuals......, participated in a follow-up at 20-34 years and was administered the Eysenck Personality Questionnaire (EPQ) which includes measures of neuroticism, extraversion, psychoticism and the so-called lie-scale. Associations of SES with each of the four personality traits were analysed by bivariate and partial...

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

  8. The plasticity of descending controls in pain: translational probing.

    Science.gov (United States)

    Bannister, Kirsty; Dickenson, A H

    2017-07-01

    Descending controls, comprising pathways that originate in midbrain and brainstem regions and project onto the spinal cord, have long been recognised as key links in the multiple neural networks that interact to produce the overall pain experience. There is clear evidence from preclinical and clinical studies that both peripheral and central sensitisation play important roles in determining the level of pain perceived. Much emphasis has been put on spinal cord mechanisms in central excitability, but it is now becoming clear that spinal hyperexcitability can be regulated by descending pathways from the brain that originate from predominantly noradrenergic and serotonergic systems. One pain can inhibit another. In this respect diffuse noxious inhibitory controls (DNIC) are a unique form of endogenous descending inhibitory pathway since they can be easily evoked and quantified in animals and man. The spinal pharmacology of pathways that subserve DNIC are complicated; in the normal situation these descending controls produce a final inhibitory effect through the actions of noradrenaline at spinal α 2 -adrenoceptors, although serotonin, acting on facilitatory spinal 5-HT 3 receptors, influences the final expression of DNIC also. These descending pathways are altered in neuropathy and the effects of excess serotonin may now become inhibitory through activation of spinal 5-HT 7 receptors. Conditioned pain modulation (CPM) is the human counterpart of DNIC and requires a descending control also. Back and forward translational studies between DNIC and CPM, gauged between bench and bedside, are key for the development of analgesic therapies that exploit descending noradrenergic and serotonergic control pathways. © 2017 The Authors.

    Endometriosis is defined as the presence of ectopic endometrial tissue outside the uterus. It is a common disease in menstruating females and intestinal involvement is not uncommon. Intestinal endometriosis most commonly involves the sigmoid colon, rectum, ileum, appendix, and cecum. However, the descending colon is a rare site of intestinal endometriosis. Although computed tomography (CT) findings of bowel endometriosis have been presented in several articles, there has been no report describing the CT findings of descending colon endometriosis above the pelvic cavity. Here, we report a rare case of descending colon endometriosis located in the retroperitoneal space, in which the initial impression was acute colonic diverticulitis with a small abscess on preoperative multidetector CT.

    Endometriosis is defined as the presence of ectopic endometrial tissue outside the uterus. It is a common disease in menstruating females and intestinal involvement is not uncommon. Intestinal endometriosis most commonly involves the sigmoid colon, rectum, ileum, appendix, and cecum. However, the descending colon is a rare site of intestinal endometriosis. Although computed tomography (CT) findings of bowel endometriosis have been presented in several articles, there has been no report describing the CT findings of descending colon endometriosis above the pelvic cavity. Here, we report a rare case of descending colon endometriosis located in the retroperitoneal space, in which the initial impression was acute colonic diverticulitis with a small abscess on preoperative multidetector CT

  13. Entanglement entropy for descendent local operators in 2D CFTs

    International Nuclear Information System (INIS)

    2015-01-01

    We mainly study the Rényi entropy and entanglement entropy of the states locally excited by the descendent operators in two dimensional conformal field theories (CFTs). In rational CFTs, we prove that the increase of entanglement entropy and Rényi entropy for a class of descendent operators, which are generated by L"("−")L̄"("−") onto the primary operator, always coincide with the logarithmic of quantum dimension of the corresponding primary operator. That means the Rényi entropy and entanglement entropy for these descendent operators are the same as the ones of their corresponding primary operator. For 2D rational CFTs with a boundary, we confirm that the Rényi entropy always coincides with the logarithmic of quantum dimension of the primary operator during some periods of the evolution. Furthermore, we consider more general descendent operators generated by ∑d_{_n__i_}_{_n__j_}(∏_iL_−_n__i∏_jL̄_−_n__j) on the primary operator. For these operators, the entanglement entropy and Rényi entropy get additional corrections, as the mixing of holomorphic and anti-holomorphic Virasoro generators enhance the entanglement. Finally, we employ perturbative CFT techniques to evaluate the Rényi entropy of the excited operators in deformed CFT. The Rényi and entanglement entropies are increased, and get contributions not only from local excited operators but also from global deformation of the theory.

    To determine (1) the short- (to hospital discharge) and long- (>6 months) term survival, (2) factors associated with short-term survival, and (3) the perioperative course for horses with resection and anastomosis of the descending colon. Multicentered case series. Horses (n=43) that had descending colon resection and anastomosis. Medical records (January 1995-June 2009) of 7 equine referral hospitals were reviewed for horses that had descending colon resection and anastomosis and were recovered from anesthesia. Retrieved data included history, results of clinical and clinicopathologic examinations, surgical findings, postsurgical treatment and complications, and short-term survival (hospital discharge). Long-term survival was defined as survival > or =6 months after hospital discharge. Of 43 horses, 36 (84%) were discharged from the hospital. Twenty-eight of 30 horses with follow-up information survived > or =6 months. No significant associations between perioperative factors and short-term survival were identified. Lesions included strangulating lipoma (n=27), postfoaling trauma (4), infarction (4), intraluminal obstruction (2), and other (6). Common postoperative complications included fever and diarrhea. During hospitalization 7 horses were euthanatized or died because of septic peritonitis (3), endotoxemia (3), and colic and ileus (1). Descending colon resection and anastomosis has a favorable prognosis for hospital discharge and survival > or =6 months. The most common cause of small colon incarceration was strangulating lipoma. Complications include postoperative fever and diarrhea but the prognosis is good after small colon resection and anastomosis.

  4. The Last Descendant of Tycho Brahe Lives in Romania

    Science.gov (United States)

    Stavinschi, M.

    On 24 October 1601 passed away, in the 55th year of his life, the great astronomer Tycho Brahe. Now, four centuries since his death, his last descendant is living in Romania: Lydia Baroness Løvendal-Papae. An encyclopedic culture and training as hers can rarely be found today; she also is an excellent specialist in genealogy and heraldry. She has not only the merit of studying the cosmic symbols in heraldry, but especially that of establishing the genealogical tree of the famous Danish astronomer. She also holds a genealogical record: as the last descendant of the old Danish dynasty, she descends from all European dynasties, including the founders of the Romanian countries. We shall dwell here neither upon the great personality of Tycho Brahe, nor on his role in the modern astronomy. We shall not refer to the Tycho catalogue resulted from the space mission Hipparcos. We shall dwell upon the ancient aristocratic family Brahe. The oldest firm mention goes as far back as in 1364, but there are data enough on the existence of some members of this family in the 13th century. The Brahe family was related to a no less famous family, that of the Barons Løvendal. One of the ancestors of Lydia Baroness Løvendal is the renowned Ulrik Frederik Voldemar, Baron, then Count Lovendal, marshal of France (1700-1755), whose name was assigned to one of the most important boulevards of Paris.

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

    International Nuclear Information System (INIS)

    Narula, Kapil; Reddy, B. Sudhakara

    2016-01-01

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

  9. The Impact of the Organism on Its Descendants

    2012-01-01

    Full Text Available Historically, evolutionary biologists have taken the view that an understanding of development is irrelevant to theories of evolution. However, the integration of several disciplines in recent years suggests that this position is wrong. The capacity of the organism to adapt to challenges from the environment can set up conditions that affect the subsequent evolution of its descendants. Moreover, molecular events arising from epigenetic processes can be transmitted from one generation to the next and influence genetic mutation. This in turn can facilitate evolution in the conditions in which epigenetic change was first initiated.

  10. Responsibility of parents for misdemeanors committed by their descendants

    Ristivojević Branislav R.

    2016-01-01

    Full Text Available The subject of the authors' attention are certain questions concerning the responsibility for the acts of other persons in the misdemeanor law of the Republic of Serbia. Under certain conditions, if a child or a minor (descendants commits a misdemeanor, instead of him or together with him, other persons can be held responsible as well, foremost his parents who had not exercised due supervision. There is a difference between the responsibility of a parent whose children have committed a misdemeanor and are under 14, and that of a parent whose children are between 14 and 18 years old. Therefore, there is a difference in terms of responsibility of the parent depending on if the person who committed the misdemeanor is, from the perspective of the Misdemeanor Law, a child or a minor. The authors critically analyze the articles of the Misdemeanor Law that concern the responsibility of the parent for the misdemeanors committed by their descendants. In the end, they conclude that the Misdemeanor Law undermines one of the essential legal principle that the 'scope of rights has to correspond to the scope of obligations and responsibility'.

  11. Bilateral anterior thalamic low densities in descending transtentorial herniation

    Energy Technology Data Exchange (ETDEWEB)

    1985-02-01

    Round, well-demarcated, symmetrical low densities in a bilateral thalamus in a case of descending transtentorial herniation due secondarily to acute traumatic left subdural hematoma are reported. An 8-year-old boy, on whom emergency surgery was refused by his parents, showed a marked shift due to the hematoma on admission; this was followed by a low density in the left PCA territory and round, equivocal hypodensities in the anterior thalamus 44 hours post-trauma. The equivocal hypodensities became definite, well-demarcated, round low densities situated symmetrically in the anterior thalamus on the 39th day post-trauma. Akinetic mutism was noted at this time. The symmetrical low densities and the PCA-territory low density persisted as late as the 39th day post-trauma, suggesting infarcts. The downward stretch of the bilateral thalamoperforators, which was effected by a narrowing of the interpeduncular fossa with an approximation of the bilateral perforators, plus a downward shift of the PCA due to descending transtentorial herniation, was assumed to be the mechanism involved.

    2013-01-01

    Full Text Available Introduction. The term “penetrating atherosclerotic ulcer” (PAU of the aorta describes the condition in which ulceration of an aortic atherosclerotic lesion penetrates the internal elastic lamina into media. PAU is a high-risk lesion due to its deleterious effects on the integrity of aortic wall, with potentially fatal outcome. Case report. A patient with intensive, sharp chest pain irradiating to the back but with no signs of myocardial ischemia on an electrocardiogram was referred to our hospital. Transthoracic echocardiography showed no pathological changes of the ascending aorta. However, multislice computed tomography (CT showed an aortic ulcer with varying degree of the subadventitial hemorrhage in the region of the thoracic aorta at the level of Th 8-9. Due to imminent rupture of the penetrating aortic ulcer, the patient was promptly prepared for surgery. A 15 cm long subadventitial hematoma was found intraoperatively in the right posterolateral aspect of the descending aorta, 5 cm above the diaphragm and 7 cm below the origin of the left subclavial artery. The affected segment of the aorta was resected, followed by an inlay aortic reconstruction with a Dacron tube graft of 24 mm. Control CT revealed satisfactory reconstruction of the descending aorta. Conclusion. PAU is a rare, but potentially fatal disease. Open surgery in patients with PAU is an effective treatment strategy, although endovascular treatment options are emerging.

    Directory of Open Access Journals (Sweden)

    Andrzej Maryniarczyk

    2016-12-01

    Full Text Available When we see in the world the fact that there are many beings, and we indicate that the particular beings exist in a compositional way, we face the task of learning about a new problem: how can we define and determine the relations between beings and between the elements within a being? Although the theory of participation has roots that go back to Plato, and so to a philosophy in which the pluralism of being was rejected and which accepted an identity-based conception of being, participation finds its ontological rational justification only (and ultimately in the pluralistic and compositional conception of being. With the description of participation as a “descending road” in the cognition of being, we are restricting ourselves to the presentation of how participation is understood in realistic metaphysics (while we shall leave aside the history of the question. We will show the aspects of participation that provide a foundation for wisdom-oriented cognition, and we will show the specific character of participation-oriented cognition as a “descending road.”

  15. An extinct vertebrate preserved by its living hybridogenetic descendant.

    Science.gov (United States)

    Dubey, Sylvain; Dufresnes, Christophe

    2017-10-06

    Hybridogenesis is a special mode of hybrid reproduction where one parental genome is eliminated and the other is transmitted clonally. We propose that this mechanism can perpetuate the genome of extinct species, based on new genetic data from Pelophylax water frogs. We characterized the genetic makeup of Italian hybridogenetic hybrids (P. kl. hispanicus and esculentus) and identified a new endemic lineage of Eastern-Mediterranean origin as one parental ancestor of P. kl. hispanicus. This taxon is nowadays extinct in the wild but its germline subsists through its hybridogenetic descendant, which can thus be considered as a "semi living fossil". Such rare situation calls for realistic efforts of de-extinction through selective breeding without genetic engineering, and fuels the topical controversy of reviving long extinct species. "Ghost" species hidden by taxa of hybrid origin may be more frequent than suspected in vertebrate groups that experienced a strong history of hybridization and semi-sexual reproduction.

    Directory of Open Access Journals (Sweden)

    Sujan Narayan Agrawal

    2017-08-01

    Full Text Available Background: The testis develops in the dorsal abdominal wall, and then descends to scrotum. The development begins as early as 6th week of intrauterine life and is completed by fifth month of intrauterine life. The testis may get arrested during its descent from dorsal abdominal wall to scrotum. The anomalies of descent includes cryptorchism (and its variant like anarchism, monarchism or partially descended testis, ectopic testis, persistent processus vaginalis and encysted hydrocoel of spermatic cord etc. Cryptorchism is usually diagnosed during the new born examination. The recognition of this condition, identification of associated syndromes, proper diagnostic evaluation and timely treatment by surgical urologist is important to prevent adverse consequences like sterility, congenital hernia & hydrocoel, testicular carcinoma etc. Objectives: the objective of this review is to study the role of gubernaculum in the testicular migration process. Material & Method: We performed a descriptive review of the literature about the role of the gubernaculum in testicular migration during the human fetal life. This article provides an overview of role of gubernaculum and other factors responsible for gonadal migration. Results: In the first phase of testicular migration the gubernaculum enlarges to hold the testis near groin and in the second phase the gubernaculum migrates across the pubic region to reach the scrotum. The proximal end of gubernaculum is attached to the testis and epididymis. The lower end reaches to bottom of scrotum. A failure in the proper functioning of gubernaculum causes cryptorchism. Rarely male gonads may deviate from main pathway due to presence of many tails of distal gubernaculum, and it may give rise to ectopic testis. The processus vaginalis usually closes by birth. If it remains patent, it leads to congenital hernia, hydrocoel, encysted hydrocoel etc. Conclusion: the gubernaculum presents a significant structure during

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

    France has the ambition to become a world leader in both nuclear industry and in renewable energies. 3 types of synergies between nuclear power and renewable energies are highlighted. First, nuclear power can be used as a low-carbon energy to produce the equipment required to renewable energy production for instance photovoltaic cells. Secondly, to benefit from the complementary features of both energies: continuous/intermittency of the production, centralized/local production. The future development of smart grids will help to do that. Thirdly, to use nuclear energy to produce massively hydrogen from water and synthetic fuels from biomass. (A.C.)

    2016-01-01

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

  8. Hypotrochoids in conformal restriction systems and Virasoro descendants

    International Nuclear Information System (INIS)

    Doyon, Benjamin

    2013-01-01

    A conformal restriction system is a commutative, associative, unital algebra equipped with a representation of the groupoid of univalent conformal maps on connected open sets of the Riemann sphere, along with a family of linear functionals on subalgebras, satisfying a set of properties including conformal invariance and a type of restriction. This embodies some expected properties of expectation values in conformal loop ensembles CLE κ (at least for 8/3 iθ and w. We find that it has an expansion in positive powers of u and u-bar , and that the coefficients of pure u ( u-bar ) powers are holomorphic in w ( w-bar ). We identify these coefficients (the ‘hypotrochoid fields’) with certain Virasoro descendants of the identity field in conformal field theory, thereby showing that they form part of a vertex operator algebraic structure. This largely generalizes works by the author (in CLE), and the author with his collaborators Riva and Cardy (in SLE 8/3 and other restriction measures), where the case of the ellipse, at the order u 2 , led to the stress–energy tensor of CFT. The derivation uses in an essential way the Virasoro vertex operator algebra structure of conformal derivatives established recently by the author. The results suggest in particular the exact evaluation of CLE expectations of products of hypotrochoid fields as well as nontrivial relations amongst them through the vertex operator algebra, and further shed light onto the relationship between CLE and CFT.

    2015-06-01

    Full Text Available Background: Extensive scholarly literature documents the decline in marriage and increase in non-marital cohabitation and divorce across regions and countries of Europe, but we know less about the extent to which these new family behaviours that have emerged in host societies are adopted by migrants. Objective: The aim of this study is to examine partnership transitions among the migrants and their descendants in Estonia, who mainly originate from the European part of Russia. By investigating an East European context, the study contributes to a more comprehensive account of migrant populations in different socio-economic and cultural settings. Methods: The study is based on the Estonian Generations and Gender Survey (2004/2005 and the Estonian Family and Fertility Survey (1994/1997, and employs proportional hazards models. Results: The results show that new family formation patterns, associated with the Second Demographic Transition, are less prevalent among migrants. The difference between migrants and native Estonians is most pronounced in the mode of partnership formation and outcomes of cohabiting unions, whereas the results pertaining to union dissolution reveal a less systematic difference between population groups. Reflecting the relatively slow integration, the second-generation migrants exhibit partnership behaviour that differs from that of the native population. The observed differences between migrants and the native population appear largely similar for both men and women. Conclusions: The results lend support to socialisation, cultural maintenance, and adaptation hypotheses, and underscore the importance of contextual factors. The analysis reveals disruption effects of migration on partnership processes.

  10. Design of SES-10 nuclear reactor for district heating

    Cuttler, J.M.

    1991-03-01

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

  17. Hybrid Approach of Aortic Diseases: Zone 1 Delivery and Volumetric Analysis on the Descending Aorta

    Directory of Open Access Journals (Sweden)

    José Augusto Duncan

    Full Text Available Abstract Introduction: Conventional techniques of surgical correction of arch and descending aortic diseases remains as high-risk procedures. Endovascular treatments of abdominal and descending thoracic aorta have lower surgical risk. Evolution of both techniques - open debranching of the arch and endovascular approach of the descending aorta - may extend a less invasive endovascular treatment for a more extensive disease with necessity of proximal landing zone in the arch. Objective: To evaluate descending thoracic aortic remodeling by means of volumetric analysis after hybrid approach of aortic arch debranching and stenting the descending aorta. Methods: Retrospective review of seven consecutive patients treated between September 2014 and August 2016 for diseases of proximal descending aorta (aneurysms and dissections by hybrid approach to deliver the endograft at zone 1. Computed tomography angiography were analyzed using a specific software to calculate descending thoracic aorta volumes pre- and postoperatively. Results: Follow-up was done in 100% of patients with a median time of 321 days (range, 41-625 days. No deaths or permanent neurological complications were observed. There were no endoleaks or stent migrations. Freedom from reintervention was 100% at 300 days and 66% at 600 days. Median volume reduction was of 45.5 cm3, representing a median volume shrinkage by 9.3%. Conclusion: Hybrid approach of arch and descending thoracic aorta diseases is feasible and leads to a favorable aortic remodeling with significant volume reduction.

  18. Argillization by descending acid at Steamboat Springs, Nevada

    Schoen, Robert; White, Donald E.; Hemley, J.J.

    1974-01-01

    Steamboat Springs, Nevada, an area of present-day hot springs, clearly illustrates the genetic dependence of some kaolin deposits on hot-spring activity. Andesite, granodiorite and arkosic sediments are locally altered at the land surface to siliceous residues consisting of primary quartz and anatase, plus opal from primary silicates. These siliceous residues commonly exhibit the textural and structural features of their unaltered equivalents. Beneath the siliceous residues, kaolin and alunite replace primary silicates and fill open spaces, forming a blanketlike deposit. Beneath the kaolin-alunite zone, montmorillonite, commonly accompanied by pyrite, replaces the primary silicates. On the ground surface, the same alteration mineral zones can be traced outward from the siliceous residue; however, hematite rather than pyrite accompanies montmorillonite.Chemical analysis indicates that sulfuric acid is the active altering agent. The acid forms from hydrogen sulfide that exsolves from deep thermal water, rises above the water table and is oxidized by sulfur-oxidizing bacteria living near the ground surface. This acid dissolves in precipitation or condensed water vapor and percolates downward destroying most of the primary minerals producing a siliceous residue. Coincidence of the water table with the downward transition from siliceous residue to kaolin-alunite signifies decreasing hydrogen metasomatism because of dilution of descending acid by ground water.In hot-spring areas, beds of siliceous sinter deposited at the surface by hypogene thermal water look, superficially, like areas of surficial acid alteration. Features diagnostic of a surficial alteration are the relict rock structures of a siliceous residue and a kaolin-alunite zone immediately beneath.

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

Participants cycled uphill on a road at race pace before descending over three conditions (off-road pedalling; off-road coasting; road coasting). Relatively low power output during off-road pedalling was associated with a greater oxygen uptake (p  .05). Importantly, pedalling did not invoke a performance benefit (p > .05) on the descent used in this study. Significantly greater heart rate and oxygen uptake (both p bike athletes focus on skills to increase descending speed without the addition of pedalling, and that equipment be used to decrease vibrations nearer to those seen on the road.

    Full Text Available A congenital membrane without intestinal malrotation is a rare cause of duodenal obstruction. Here we present an 11-year-old girl who had suffered from intermittent abdominal cramping pain and vomiting for more than 5 years. The image studies, including a plain abdomen roentgenogram and sonogram, showed no definite diagnosis. The upper gastrointestinal series and small bowel series showed the contrast was static over the third portion of the duodenum and the descending colon pulled up toward the epigastric area. Laparoscopic exploration revealed a congenital membrane extending from the right-side paraduodenal peritoneum through the third portion of the duodenum to the descending colon, which had caused obstruction of the third portion of the duodenum and malpositioning of the descending colon. To the best of our knowledge, this is the first case report in the literature where a congenital membrane caused both duodenal obstruction and malpositioning of the descending colon.

    Thrombus formation in an atherosclerotic or aneurysmal descending thoracic aorta is a well-described, frequently encountered vascular condition. In comparison, thrombus formation in a normal-appearing descending thoracic aorta is reported far less often. We describe the case of a 46-year-old woman who had splenic and renal infarctions secondary to embolic showers from a large, mobile thrombus in a morphologically normal proximal descending thoracic aorta. After the patient underwent anticoagulation, stent-grafting, and surgical bypass to correct an arterial blockage caused by the stent-graft, she resumed a relatively normal life. In contrast with other cases of a thrombotic but normal-appearing descending thoracic aorta, this patient had no known malignancy or systemic coagulative disorders; her sole risk factor was chronic smoking. We discuss our patient's case and review the relevant medical literature, focusing on the effect of smoking on coagulation physiology. PMID:24391341

    Full Text Available This report presents an operative case of advanced descending colon cancer in an adult patient with intestinal malrotation. A 63-year-old Japanese male was suffering from left side abdominal pain, abdominal distension, and constipation. An endoscopic examination revealed an advanced tumor in the descending colon. Computed tomography (CT of the abdomen revealed the thickening of the descending colon wall and superior mesenteric vein rotation. An opaque enema detected severe stenosis of the descending colon. An abdominal X-ray examination revealed the dilation of the colon and small intestine with niveau. At the insertion of an ileus tube, the C-loop of the duodenum was observed to be absent and the small intestine was located on the right side of the abdomen. After the decompression of the bowel contents, laparotomy was performed. Descending colon cancer was observed to have directly invaded the left side of the transverse colon. Left hemicolectomy, lymph node dissection, and appendectomy were performed. The patient had an uneventful recovery and was discharged from the hospital on the 16th day after surgery. This report presents a rare operative case of descending colon cancer in an adult patient with intestinal malrotation.

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

    2016-05-01

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

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

    Science.gov (United States)

    Koltai, Jonathan; Schieman, Scott

    2015-06-01

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

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

  2. Effects of ascending and descending climbers on space elevator cable dynamics

    2018-04-01

    Based on a mass-point model, the cable dynamics of a space elevator during a climber's travel motion are examined. The cable response during a single operation of one ascending or descending climber is analyzed first, and then, based on the results, the cable dynamics for simultaneous operation of an ascending and a descending climber are evaluated. For the single operation, bending is significant when the climber is traveling near the Earth's surface. The cable also inclines with periodic oscillation as a result of a Coriolis force corresponding to the climber velocity. However, simultaneous operation of ascending and descending climbers can suppress the inclination of the cable by almost a factor of ten. In simultaneous operation, compared to single operation, a descending climber has a smaller amplitude of libration angle and less cable bending, while an ascending climber has a smaller amplitude when the climber is traveling at a higher altitude with climber velocities of 200 km/h and 400 km/h. The phase of the oscillation of the overall cable is found to be close to that of the descending climber. Cable bending is suppressed for any examined climber velocity, but the dependency of this suppression of displacement on climber velocity is not found. In summary, simultaneous operation can surely suppress the inclination of the cable via the cancellation of Coriolis forces by the two climbers.

    Supermassive blackholes with masses of a billion solar masses or more are known to exist up to z = 7. However, the present-day environments of the descendants of first quasars are not well understood and it is not known if they live in massive galaxy clusters or more isolated galaxies at z = 0. We use a dark matter-only realization (BTMassTracer) of the BlueTides cosmological hydrodynamic simulation to study the halo properties of the descendants of the most massive black holes at z = 8. We find that the descendants of the quasars with most massive black holes are not amongst the most massive haloes. They reside in haloes of with group-like (˜1014 M⊙) masses, while the most massive haloes in the simulations are rich clusters with masses ˜1015 M⊙. At z = 0, the distribution of halo masses of these quasar descendants is similar to that of the descendants of least massive black holes, which indicates that they are likely to exist in similar environments. By tracing back to the z = 8 progenitors of the most massive (cluster sized) haloes at z = 0; we find that their most likely black hole mass is less than 107 M⊙; they are clearly not amongst the most massive black holes. For haloes above 1015 M⊙, there is only 20 per cent probability that their z = 8 progenitors hosted a black hole with mass above 107 M⊙.

    Pontine noradrenergic neurones form part of a descending inhibitory system that influences spinal nociceptive processing. Weak or absent descending inhibition is a common feature of chronic pain patients. We examined the extent to which the descending noradrenergic system is tonically active, how control of spinal neuronal excitability is integrated into thalamic relays within sensory-discriminative projection pathways, and how this inhibitory control is altered after nerve injury. In vivo electrophysiology was performed in anaesthetised spinal nerve ligated (SNL) and sham-operated rats to record from wide dynamic range neurones in the ventral posterolateral thalamus (VPL). In sham rats, spinal block of α2-adrenoceptors with atipamezole resulted in enhanced stimulus-evoked and spontaneous firing in the VPL, and produced conditioned place avoidance. However, in SNL rats these conditioned avoidance behaviours were absent. Furthermore, inhibitory control of evoked neuronal responses was lost but spinal atipamezole markedly increased spontaneous firing. Augmenting spinal noradrenergic tone in neuropathic rats with reboxetine, a selective noradrenergic reuptake inhibitor, modestly reinstated inhibitory control of evoked responses in the VPL but had no effect on spontaneous firing. In contrast, clonidine, an α2 agonist, inhibited both evoked and spontaneous firing, and exhibited increased potency in SNL rats compared to sham controls. These data suggest descending noradrenergic inhibitory pathways are tonically active in sham rats. Moreover, in neuropathic states descending inhibitory control is diminished, but not completely absent, and distinguishes between spontaneous and evoked neuronal activity. These observations may have implications for how analgesics targeting the noradrenergic system provide relief.

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

    2011-03-01

    Quiet standing and walking are generally considered to be an automatic process regulated by sensory feedback. In our report "Astasia without abasia due to peripheral neuropathy," which was published in 1994, we proposed that forced stepping in patients lacking the ankle torque is a compensatory motor control in order to maintain an upright posture. A statistical-biomechanics approach to the human postural control system has revealed open-loop (descending) control as well as closed-loop (feedback) control in quiet standing, and fractal dynamics in stride-to-stride fluctuations of walking. The descending control system of bipedal upright posture and gait may have a functional link to cognitive domains. Increasing dependence on the descending control system with aging may play a role in falls in elderly people.

    Full Text Available Background: There is a growing literature on the dynamics of immigrant fertility and mixed marriages, but partnership transitions among immigrants and ethnic minorities are little studied. Objective: This study investigates union formation and dissolution among immigrants and their descendants in the UK. Methods: We use data from the Understanding Society study and apply the techniques of event history analysis. We contrast partnership trajectories of various immigrant groups and compare these with those of the 'native' British population. Results: The analysis shows significant differences in partnership formation and dissolution among immigrants and ethnic minorities. Women of Caribbean origin have the highest cohabitation and the lowest marriage rates, whereas cohabitation remains rare among immigrants from South Asia and their descendants, as most of them marry directly. Immigrants from the Caribbean region and their descendants also show higher divorce rates than 'native' British women, whereas women of South Asian origin have a low divorce risk.

    In larval lamprey, partial lesions were made in the rostral spinal cord to determine which spinal tracts are important for descending activation of locomotion and to identify descending brain neurons that project in these tracts. In whole animals and in vitro brain/spinal cord preparations, brain-initiated spinal locomotor activity was present when the lateral or intermediate spinal tracts were spared but usually was abolished when the medial tracts were spared. We previously showed that descending brain neurons are located in eleven cell groups, including reticulospinal (RS) neurons in the mesenecephalic reticular nucleus (MRN) as well as the anterior (ARRN), middle (MRRN), and posterior (PRRN) rhombencephalic reticular nuclei. Other descending brain neurons are located in the diencephalic (Di) as well as the anterolateral (ALV), dorsolateral (DLV), and posterolateral (PLV) vagal groups. In the present study, the Mauthner and auxillary Mauthner cells, most neurons in the Di, ALV, DLV, and PLV cell groups, and some neurons in the ARRN and PRRN had crossed descending axons. The majority of neurons projecting in medial spinal tracts included large identified Müller cells and neurons in the Di, MRN, ALV, and DLV. Axons of individual descending brain neurons usually did not switch spinal tracts, have branches in multiple tracts, or cross the midline within the rostral cord. Most neurons that projected in the lateral/intermediate spinal tracts were in the ARRN, MRRN, and PRRN. Thus, output neurons of the locomotor command system are distributed in several reticular nuclei, whose neurons project in relatively wide areas of the cord. PMID:20510243

    2015-09-01

    Diffuse noxious inhibitory controls (DNICs) utilize descending inhibitory controls through poorly understood brain stem pathways. The human counterpart, conditioned pain modulation, is reduced in patients with neuropathy aligned with animal data showing a loss of descending inhibitory noradrenaline controls together with a gain of 5-HT3 receptor-mediated facilitations after neuropathy. We investigated the pharmacological basis of DNIC and whether it can be restored after neuropathy. Deep dorsal horn neurons were activated by von Frey filaments applied to the hind paw, and DNIC was induced by a pinch applied to the ear in isoflurane-anaesthetized animals. Spinal nerve ligation was the model of neuropathy. Diffuse noxious inhibitory control was present in control rats but abolished after neuropathy. α2 adrenoceptor mechanisms underlie DNIC because the antagonists, yohimbine and atipamezole, markedly attenuated this descending inhibition. We restored DNIC in spinal nerve ligated animals by blocking 5-HT3 descending facilitations with the antagonist ondansetron or by enhancing norepinephrine modulation through the use of reboxetine (a norepinephrine reuptake inhibitor, NRI) or tapentadol (μ-opioid receptor agonist and NRI). Additionally, ondansetron enhanced DNIC in normal animals. Diffuse noxious inhibitory controls are reduced after peripheral nerve injury illustrating the central impact of neuropathy, leading to an imbalance in descending excitations and inhibitions. Underlying noradrenergic mechanisms explain the relationship between conditioned pain modulation and the use of tapentadol and duloxetine (a serotonin, NRI) in patients. We suggest that pharmacological strategies through manipulation of the monoamine system could be used to enhance DNIC in patients by blocking descending facilitations with ondansetron or enhancing norepinephrine inhibitions, so possibly reducing chronic pain.

    Due to range safety considerations, the Sea-viewing Wide Field-of-view Sensor (SeaWiFS) ocean color instrument may be required to be launched into a near-noon descending node, as opposed to the ascending node used by the predecessor sensor, the Coastal Zone Color Scanner (CZCS). The relative importance of ascending versus descending near-noon orbits was assessed here to determine if descending node will meet the scientific requirements of SeaWiFS. Analyses focused on ground coverage, local times of coverage, solar and viewing geometries (zenith and azimuth angles), and sun glint. Differences were found in the areas covered by individual orbits, but were not important when taken over a 16 day repeat time. Local time of coverage was also different: for ascending node orbits the Northern Hemisphere was observed in the morning and the Southern Hemisphere in the afternoon, while for descending node orbits the Northern Hemisphere was observed in the afternoon and the Southern in the morning. There were substantial differences in solar azimuth and spacecraft azimuth angles both at equinox and at the Northern Hemisphere summer solstice. Negligible differences in solar and spacecraft zenith angles, relative azimuth angles, and sun glint were obtained at the equinox. However, large differences were found in solar zenith angles, relative azimuths, and sun glint for the solstice. These differences appeared to compensate across the scan, however, an increase in sun glint in descending node over that in ascending node on the western part of the scan was compensated by a decrease on the eastern part of the scan. Thus, no advantage or disadvantage could be conferred upon either ascending node or descending node for noon orbits. Analyses were also performed for ascending and descending node orbits that deviated from a noon equator crossing time. For ascending node, afternoon orbits produced the lowest mean solar zenith angles in the Northern Hemisphere, and morning orbits produced

    A German shepherd dog was presented two months after surgery for correction of acute gastric dilatation volvulus. The dog had been diagnosed with exocrine pancreatic insufficiency. Radiographs revealed marked gaseous distension of one loop of intestine with a generalised increase in intestinal gas content. A 360 degrees anticlockwise rotation of the descending and transverse colon, around the longitudinal axis of the mesocolon, was diagnosed at exploratory coeliotomy. The transverse and descending colon appeared uniformly necrotic and an end-to-end colo-colic resection and anastomosis was performed. The dog initially made satisfactory postoperative progress but was euthanased on the third postoperative day after it developed an intestinal intussusception.

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

    2009-07-01

    Full Text Available This article lays out, in general terms, what it calls the political camp of Afro-descendents in Latin America. After establishing a series of theoretical and methodological criteria for the historical analysis of black movements in modernity and the Afro-American movements in particular, the article focuses on the emergence of afro-descendant movements in Latin America during the last part of the 1980s. One of the principal arguments is that in the 1990s a political camp of afro-descendents starts to emerge in the region of Latin America based on a series of developments, including the emergence of new social movements that included ethno-racial movements of Afros and indigenous people, events of regional importance like the contra-celebration of 1492 in 1992, the World Conference against Racism 2001 in Durban, South Africa, and the effects of the neoliberal pattern of globalization. The political camp of Afro-descendents is composed not only of social movements, but also of state actors and transnational actors (such as the World Bank and the Ford Foundation. The article concludes with an analysis of the challenges and perspectives of Afro-American politics in general and of Afro-Latin movements in particular considering the current crisis of the modern/colonial world-system.

    2004-01-01

    The saccharidic content of the glycoconjugates has been studied in the descended the undescended testes of a 8 years old boy. For this purpose, a battery of seven HRP-conjugated lectins (SBA, DBA,PNA,WGA,UEAI, LTA and ConA) was used. D-galactose-N-acetyl-D-galactosamine and alpha-L-fucose sugar residues, which were present in the cytoplasm of the Sertoli cells of the normally positioned prepubertal testis, were not detected in the same cells of the undescended testis. The Leydig's cells of the descended testis appeared characterized by N-acetyl-D-glucosamine which was absent in the rare and atrophic Leydig's cells of the cryptorchid testis. Differences in sugar residues distribution between the descended and the undescended testis were also detected in the lamina propria of the seminiferous tubules. Peritubular myoid cells in the undescended testis only reacted with PNA, after neuraminidase digestion, thus revealing the presence of D-galactose (beta1-->3)-N-acetyl-D-galactosamine and sialic acid. In this study a complete distributional map of the sugar residues of the glycoconjugates in the descended and undescended prepubertal testis is reported.

  2. Are immigrants and descendants with ill health more prone to unemployment? Evidence from 18 European countries.

    Science.gov (United States)

    Heggebø, Kristian

    2017-08-01

    Previous research has established that both ill health and minority status are associated with unemployment. Less is known, however, about the interplay between having ill health and being from minority background. The present study examines whether immigrants and descendants with ill health are particularly prone to unemployment during an economic downturn in Europe. The European Union Statistics on Income and Living Conditions (EU-SILC) cross-sectional data material is utilized, and linear probability models are estimated. The analysis is run for countries in which the two minority samples are acceptably large (N ≥ 100), resulting in 18 included European countries. The year 2011 is chosen because it is possible to identify both immigrants and descendants in EU-SILC due to a module on intergenerational transfer of disadvantages. The results indicate - as expected - that both ill health and minority status are independently related to higher unemployment likelihood. Immigrants and descendants with ill health, however, are not particularly likely to be unemployed. This finding is robust to a number of sensitivity tests, and the empirical pattern is very similar across the 18 included countries. Both minority status and ill health are associated with high unemployment probability in Europe. However, there does not seem to exist a 'double disadvantage' for immigrants and descendants with ill health, which is in line with a human capital perspective on how employers evaluate potential employees. Both a non-native-sounding name and bad health status are interpreted as a risk factor, but there is no reason to expect ill health to lower the productivity level more if the applicant is a descendant or immigrant.

  9. Whiplash evokes descending muscle recruitment and sympathetic responses characteristic of startle

    Science.gov (United States)

    Mang, Daniel WH; Siegmund, Gunter P; Blouin, Jean-Sébastien

    2014-01-01

    Whiplash injuries are the most common injuries following rear-end collisions. During a rear-end collision, the human muscle response consists of both a postural and a startle response that may exacerbate injury. However, most previous studies only assessed the presence of startle using data collected from the neck muscles and head/neck kinematics. The startle response also evokes a descending pattern of muscle recruitment and changes in autonomic activity. Here we examined the recruitment of axial and appendicular muscles along with autonomic responses to confirm whether these other features of a startle response were present during the first exposure to a whiplash perturbation. Ten subjects experienced a single whiplash perturbation while recording electromyography, electrocardiogram, and electrodermal responses. All subjects exhibited a descending pattern of muscle recruitment, and increasing heart rate and electrodermal responses following the collision. Our results provide further support that the startle response is a component of the response to whiplash collisions. PMID:24932015

    2016-12-01

    Full Text Available This research works toward the identification of the factors that comprise the process of socialization, involvement and initial belonging of descendants in family businesses and the key relationships between them. By means of a qualitative detailed study of four cases, complemented by a quantitative survey of 274 Colombian family businesses, the authors generate a new model that takes into account both factors explored in previous research as well as others identified in this study. Findings confirm the specific dependency of each stage on the subsequent ones; socialization influences involvement, which in turn influences the belonging of the descendants to the family business, with a strong presence of factors such as knowledge, leadership, mode, timing, and motivation. Those responsible for the orientation of potential successors may examine these findings in order to optimize their preparation efforts and support of family human resources for the continuity of the business.

    Descending necrotizing mediastinitis (DNM) following dental extraction is an extremely serious infection with a high mortality rate. Oral infection may rapidly descend into the mediastinum across the retropharyngeal and retrovisceral spaces. Once established, mediastinitis is rapidly followed by sepsis and death. If DNM is suspected cervical and thoracic CT must be carried out urgently. After this, prompt control of the upper airway with tracheostomy, aggressive surgical debridement of the deep cervical spaces and mediastinum, and intravenous broad spectrum antibiotic therapy are mandatory. The present paper reports two new cases of DNM following dental extraction, and focuses on radiological features of abscess progression through the cervical spaces down into the mediastinum. 2010 European Association for Cranio-Maxillo-Facial Surgery.

  12. Discrete torsion in non-geometric orbifolds and their open-string descendants

    International Nuclear Information System (INIS)

    Bianchi, Massimo; Morales, Jose F.; Pradisi, Gianfranco

    2000-01-01

    We discuss some Z N L xZ N R orbifold compactifications of the type IIB superstring to D=4,6 dimensions and their type I descendants. Although the Z N L xZ N R generators act asymmetrically on the chiral string modes, they result into left-right symmetric models that admit sensible unorientable reductions. We carefully work out the phases that appear in the modular transformations of the chiral amplitudes and identify the possibility of introducing discrete torsion. We propose a simplifying ansatz for the construction of the open-string descendants in which the transverse-channel Klein-bottle, annulus and Moebius-strip amplitudes are numerically identical in the proper parametrization of the world-sheet. A simple variant of the ansatz for the Z 2 L xZ 2 R orbifold gives rise to models with supersymmetry breaking in the open-string sector

  13. Papillary Adenocarcinoma of the descending colon in a dog: case report

    Directory of Open Access Journals (Sweden)

    M.G.P.A. Ferreira

    Full Text Available ABSTRACT The aim of this report was to describe the clinical findings and therapeutic management of a case of papillary adenocarcinoma of the descending colon in a Beagle. The patient presented soft stools, haematochezia, tenesmus, and dyschezia. Clinical examination revealed alterations on the ultrasonographic features of the descending colon suggestive of colitis and neoplasia. Following local mass resection, histopathology analysis revealed mild lymphoplasmocytic enteritis and papillary adenocarcinoma of the colon. Enterectomy for tumoral resection and biopsy of locoregional lymph nodes were carried out. Subsequent to the surgical procedure, it was possible to confirm the previous diagnosis and the tumor was classified as intestinal intraluminal papillary adenocarcinoma, with incomplete surgical margins. Adjuvant chemotherapy was performed using carboplatin, cyclophosphamide, and piroxicam, leading to remission of clinical signs and absence of any clinical or imaging alterations compatible with the patient’s previous clinical condition.

  14. The Role of Descending Modulation in Manual Therapy and Its Analgesic Implications: A Narrative Review

    Directory of Open Access Journals (Sweden)

    Andrew D. Vigotsky

    2015-01-01

    Full Text Available Manual therapy has long been a component of physical rehabilitation programs, especially to treat those in pain. The mechanisms of manual therapy, however, are not fully understood, and it has been suggested that its pain modulatory effects are of neurophysiological origin and may be mediated by the descending modulatory circuit. Therefore, the purpose of this review is to examine the neurophysiological response to different types of manual therapy, in order to better understand the neurophysiological mechanisms behind each therapy’s analgesic effects. It is concluded that different forms of manual therapy elicit analgesic effects via different mechanisms, and nearly all therapies appear to be at least partially mediated by descending modulation. Additionally, future avenues of mechanistic research pertaining to manual therapy are discussed.

  15. Experimental and numerical investigations of coke descending behavior in a coke dry quenching cooling shaft

    2008-01-01

    A viscous flow model based on the Navier-Stokes equation is developed to describe coke descending behavior in the 1/7-scaled-down experimental setup of an actual 75 t/h cooling shaft. It is found that the internal friction due to cokes viscosity significantly influences the descending behavior of cokes in the lower part of the shaft, while the external wall friction dominates the sluggish flow of the cokes in the shaft. An asymptotic friction coefficient expression is proposed for granular mixtures flowing along the shaft wall modified from normal wall tress, and the concept of bulk solid viscosity is introduced to describe the internal friction between coke particles. The results simulated by the present model are compared with those by the potential flow and the kinematic model without friction. The viscous flow model is quite good to simulate the bulk coke flow as the physically important frictions are engaged

  16. The importance of the descending monoamine system for the pain experience and its treatment

    Science.gov (United States)

    Dickenson, Anthony H

    2009-01-01

    Brainstem and midbrain areas engage descending facilitatory and inhibitory neurones to potentiate or suppress the passage of sensory inputs from spinal loci to the brain. The balance between descending controls, both excitatory and inhibitory, can be altered in various pain states and can critically determine the efficacy of certain analgesic drugs. There is good evidence for a prominent α2 adrenoceptor-mediated inhibitory system and for 5-HT3 receptor-mediated excitatory control of spinal cord activity that originates in supraspinal areas. Given the multiple roles of these transmitters in pain and functions such as sleep, depression, and anxiety, the link between spinal and supraspinal processing of noxious inputs (via the monoamine transmitters) could be pivotal for linking the sensory and affective components of pain and their common co-morbidities, and also may potentially explain differences in pain scores and treatment outcomes in the patient population.

    2012-01-01

    We report a case of descending colon carcinoma metastasized to the left spermatic cord, testis, and epididymis. A 77-year old male patient underwent a left hemicolectomy for a descending colon cancer. He was referred to our department because of swelling and pain of the left scrotum two years and six months after surgery. High left orchiectomy was performed. Histological examination revealed a metastasis of the colon carcinoma within the spermatic cord and epididymis approaching the testicle. Reports on metastatic cancer of the testis are scarce, because this metastatic cancer is extremely rare. In general, testicular pain is rare in the elderly. We suggest that any elder presenting with testicular pain deserves a complete clinical and diagnostic evaluation. PMID:24578939

    2015-10-01

    Wandering spleen is a rare condition, characterized by a mobile spleen that is attached only by an elongated vascular pedicle, allowing it to migrate to any part of the abdomen or pelvis. Mesenteroaxial gastric volvulus usually occurs in children and may be associated with wandering spleen. Both entities result from abnormal laxity or absence of the peritoneal attachments due to abnormal fusion of the peritoneal mesenteries. Pancreatic volvulus is a very rare anomaly, with only a few isolated case reports described in association with wandering spleen. Anomalous right sided descending and sigmoid colon is a very rare entity and its association with wandering spleen has not been previously reported. We report a case of wandering spleen associated with mesenteroaxial gastric volvulus, pancreatic volvulus and rightward shift of the splenic flexure of the colon and right sided descending and sigmoid colon in a young female.

  20. Role of thin descending limb urea transport in renal urea handling and the urine concentrating mechanism

    Science.gov (United States)

    Lei, Tianluo; Zhou, Lei; Layton, Anita T.; Zhou, Hong; Zhao, Xuejian; Bankir, Lise

    2011-01-01

    Urea transporters UT-A2 and UT-B are expressed in epithelia of thin descending limb of Henle's loop and in descending vasa recta, respectively. To study their role and possible interaction in the context of the urine concentration mechanism, a UT-A2 and UT-B double knockout (UT-A2/B knockout) mouse model was generated by targeted deletion of the UT-A2 promoter in embryonic stem cells with UT-B gene knockout. The UT-A2/B knockout mice lacked detectable UT-A2 and UT-B transcripts and proteins and showed normal survival and growth. Daily urine output was significantly higher in UT-A2/B knockout mice than that in wild-type mice and lower than that in UT-B knockout mice. Urine osmolality in UT-A2/B knockout mice was intermediate between that in UT-B knockout and wild-type mice. The changes in urine osmolality and flow rate, plasma and urine urea concentration, as well as non-urea solute concentration after an acute urea load or chronic changes in protein intake suggested that UT-A2 plays a role in the progressive accumulation of urea in the inner medulla. These results suggest that in wild-type mice UT-A2 facilitates urea absorption by urea efflux from the thin descending limb of short loops of Henle. Moreover, UT-A2 deletion in UT-B knockout mice partially remedies the urine concentrating defect caused by UT-B deletion, by reducing urea loss from the descending limbs to the peripheral circulation; instead, urea is returned to the inner medulla through the loops of Henle and the collecting ducts.

  1. A Computational Model of a Descending Mechanosensory Pathway Involved in Active Tactile Sensing.

    Full Text Available Many animals, including humans, rely on active tactile sensing to explore the environment and negotiate obstacles, especially in the dark. Here, we model a descending neural pathway that mediates short-latency proprioceptive information from a tactile sensor on the head to thoracic neural networks. We studied the nocturnal stick insect Carausius morosus, a model organism for the study of adaptive locomotion, including tactually mediated reaching movements. Like mammals, insects need to move their tactile sensors for probing the environment. Cues about sensor position and motion are therefore crucial for the spatial localization of tactile contacts and the coordination of fast, adaptive motor responses. Our model explains how proprioceptive information about motion and position of the antennae, the main tactile sensors in insects, can be encoded by a single type of mechanosensory afferents. Moreover, it explains how this information is integrated and mediated to thoracic neural networks by a diverse population of descending interneurons (DINs. First, we quantified responses of a DIN population to changes in antennal position, motion and direction of movement. Using principal component (PC analysis, we find that only two PCs account for a large fraction of the variance in the DIN response properties. We call the two-dimensional space spanned by these PCs 'coding-space' because it captures essential features of the entire DIN population. Second, we model the mechanoreceptive input elements of this descending pathway, a population of proprioceptive mechanosensory hairs monitoring deflection of the antennal joints. Finally, we propose a computational framework that can model the response properties of all important DIN types, using the hair field model as its only input. This DIN model is validated by comparison of tuning characteristics, and by mapping the modelled neurons into the two-dimensional coding-space of the real DIN population. This

    The commonly used Darling classification for total anomalous pulmonary venous connection (TAPVC) consists of supracardiac, cardiac, infracardiac, and mixed types (Craig et al., Lab Invest 6:44-64, 1967). In supracardiac TAPVC, the common pulmonary vein drains superiorly into the left innominate vein, the superior vena cava, or the azygos vein by way of an ascending vertical vein. We describe a case of supracardiac TAPVC draining into the azygos vein atypically by way of a descending vertical vein.

  4. Interictal dysfunction of a brainstem descending modulatory center in migraine patients.

    Directory of Open Access Journals (Sweden)

    Eric A Moulton

    Full Text Available The brainstem contains descending circuitry that can modulate nociceptive processing (neural signals associated with pain in the dorsal horn of the spinal cord and the medullary dorsal horn. In migraineurs, abnormal brainstem function during attacks suggest that dysfunction of descending modulation may facilitate migraine attacks, either by reducing descending inhibition or increasing facilitation. To determine whether a brainstem dysfunction could play a role in facilitating migraine attacks, we measured brainstem function in migraineurs when they were not having an attack (i.e. the interictal phase.Using fMRI (functional magnetic resonance imaging, we mapped brainstem activity to heat stimuli in 12 episodic migraine patients during the interictal phase. Separate scans were collected to measure responses to 41 degrees C and noxious heat (pain threshold+1 degrees C. Stimuli were either applied to the forehead on the affected side (as reported during an attack or the dorsum of the hand. This was repeated in 12 age-gender-matched control subjects, and the side tested corresponded to that in the matched migraine patients. Nucleus cuneiformis (NCF, a component of brainstem pain modulatory circuits, appears to be hypofunctional in migraineurs. 3 out of the 4 thermal stimulus conditions showed significantly greater NCF activation in control subjects than the migraine patients.Altered descending modulation has been postulated to contribute to migraine, leading to loss of inhibition or enhanced facilitation resulting in hyperexcitability of trigeminovascular neurons. NCF function could potentially serve as a diagnostic measure in migraine patients, even when not experiencing an attack. This has important implications for the evaluation of therapies for migraine.

    In recent times, significant effort has been made to understand the mechanical behaviour of the arterial wall and how it is affected by the different vascular pathologies. However, to be able to interpret the results correctly, it is essential that the influence of other factors, such as aging or anisotropy, be understood. Knowledge of mechanical behaviour of the aorta has been customarily constrained by lack of data on fresh aortic tissue, especially from healthy young individuals. In addition, information regarding the point of rupture is also very limited. In this study, the mechanical behaviour of the descending thoracic aorta of 28 organ donors with no apparent disease, whose ages vary from 17 to 60 years, is evaluated. Tensile tests up to rupture are carried out to evaluate the influence of age and wall anisotropy. Results reveal that the tensile strength and stretch at failure of healthy descending aortas show a significant reduction with age, falling abruptly beyond the age of 30. This fact places age as a key factor when mechanical properties of descending aorta are considered

    2017-01-01

    Schwannomas of the descending loop of the hypoglossal nerve are very rare. They are slow-growing tumors that may masquerade a carotid body tumor. A 60-year-old female was referred for a latero-cervical mass appearing as a chemodectoma at CT-scan. At operation, a 2cm mass arising from the descending loop of the hypoglossal nerve was resected en bloc with the loop itself and a functional lymphadenectomy was associated. Post-operative course was uneventful and the patient is free from disease recurrence at one year follow-up. En bloc resection remains the real curative treatment of Schwannomas, ensuring unlimited freedom from disease, although causing functional impairment which may be significant. Nonetheless recurrence should be prevented as, beside requiring reintervention, it may harbor a malignant evolution towards sarcoma. Schwannomas of the descending lop of the hypoglossal nerve may masquerade a chemodectoma of the carotid bifurcation and can be curatively resected without any functional impairment.

    Full Text Available Introduction. The role of neurotransmitter systems in the motor activity of longitudinal or circular muscles in autonomic regulation of the motility of the colon by the nervous system is unclear. The aim of the study was to investigate the neurotransmitter implications in descending motility of longitudinal and circular muscles in rat colon. Methods. Electrically-induced (2, 5 or 10 Hz, 0.8 ms, 40 V, 20 s local or descending motor responses of longitudinal and circular muscles in isolated preparations and drugs were used to define the neurotransmitters’ role in colonic motility. Results. The spontaneous activity of the distal part of preparations manifested as high-amplitude irregular contractions more expressed in the longitudinal muscles. The electrically-induced local responses differed considerably in the two muscles: in longitudinal muscle there were frequency-dependent contractions, while initial relaxation followed by contraction was observed in circular muscle. The descending motor response resembled the pattern of the local responses, but the amplitudes were significantly less expressed, as compared to the respective local responses.

    Full Text Available Abstract Introduction Cervical necrotizing fasciitis is an aggressive infection with high morbidity and mortality. We present a case of cervical necrotizing fasciitis and descending mediastinitis in a healthy young man, caused by unilateral tonsillitis with a successful outcome without aggressive debridement. Case presentation A 41-year-old man was admitted to our unit with a diagnosis of severe acute unilateral tonsillitis. On admission, he had painful neck movements and the skin over his neck was red, hot and tender. Computed tomography scan of his neck and chest showed evidence of cervical necrotizing fasciitis and descending mediastinitis secondary to underlying pharyngeal disease. He was treated with broad-spectrum intravenous antibiotics. His condition improved over the next 3 days but a tender and fluctuant swelling appeared in the suprasternal region. A repeat scan showed the appearance of an abscess extending from the pretracheal region to the upper mediastinum which was drained through a small transverse anterior neck incision. After surgery, the patient's condition quickly improved and he was discharged on the 18th day of admission. Conclusion Less invasive surgical techniques may replace conventional aggressive debridement as the treatment of choice for cervical necrotizing fasciitis and descending necrotizing mediastinitis.

  11. Opportunities for mourning when grief is disenfranchised: descendants of Nazi perpetrators in dialogue with Holocaust survivors.

    Science.gov (United States)

    Livingston, Kathy

    2010-01-01

    This article explores the concepts of unmourned and disenfranchised grief as a way to understand the experiences of adult children of Nazi perpetrators, who grew up with cultural norms of grieving alone or in silence. The scholarly literature on descendants of Nazis reflects a group unlikely to warrant empathy or support from others because of the stigma surrounding their family's possible involvement in the Holocaust atrocities. This article uses, as a case study approach, the testimony given by Monika Hertwig, the adult daughter of a high ranking Nazi, who appears in the documentary film, Inheritance. From the perspective of disenfranchised grief, defined as grief that is not socially recognized or supported, the article links Monika's testimony with existing research from in-depth interviews with other descendants of Nazis to suggest that, as a group, they lacked permission to grieve their deceased parents, acknowledgment of their grief, and opportunities to mourn. Based on the theory that the effects of grief can be transgenerational, the disenfranchisement experienced by the "children of the Third Reich" does not have to pass to subsequent generations if opportunities for mourning are made possible and some resolution of grief occurs. Studies have shown that ongoing dialogue groups between Holocaust survivors and descendants of Nazis provide opportunities for mourning to both groups.

    The feasibility, safety and oncological outcomes of laparoscopic surgery for transverse and descending colon cancers in a community hospital setting were evaluated. Twenty-six patients with transverse or descending colon cancers who underwent laparoscopic surgery at our hospital were included in this retrospective analysis (group A). Their outcomes were compared with those of 71 patients who underwent laparoscopic surgery for colon cancer at other tumor sites (group B). There were no significant differences between the two groups in terms of operative time, estimated blood loss, postoperative hospital stay and morbidity rate. Extended lymphadenectomy was performed more frequently and the number of harvested lymph nodes was significantly higher in group B than in group A. However, no recurrence developed in group A, while recurrence occurred in four patients from group B. The 3-year disease-free survival rates were 100% for group A and 93.5% for group B. The 3-year overall survival rates were 100% for group A and 91.6% for group B. Laparoscopic surgery for transverse and descending colon cancers can be performed safely with oncological validity in a community hospital setting, provided there is careful selection of the patients and adequate lymphadenectomy considering the clinical stage of their disease. © 2013 Japan Society for Endoscopic Surgery, Asia Endosurgery Task Force and Wiley Publishing Asia Pty Ltd.

    To evaluate the efficiency of the descending hypoglossal branch-facial nerve anastomosis for the severe facial palsy after acoustic neuroma resection. The clinical data of 14 patients (6 males, 8 females, average age 45. 6 years old) underwent descending hypoglossal branch-facial nerve anastomosis for treatment of unilateral facial palsy was analyzed retrospectively. All patients previously had undergone resection of a large acoustic neuroma. House-Brackmann (H-B) grading system was used to evaluate the pre-, post-operative and follow up facial nerve function status. 12 cases (85.7%) had long follow up, with an average follow-up period of 24. 6 months. 6 patients had good outcome (H-B 2 - 3 grade); 5 patients had fair outcome (H-B 3 - 4 grade) and 1 patient had poor outcome (H-B 5 grade) Only 1 patient suffered hemitongue myoparalysis owing to the operation. Descending hypoglossal branch-facial nerve anastomosis is effective for facial reanimation, and it has little impact on the function of chewing, swallowing and pronunciation of the patients compared with the traditional hypoglossal-facial nerve anastomosis.

    Full Text Available The formation of the Brazilian Amazonian population has historically involved three main ethnic groups, Amerindian, African and European. This has resulted in genetic investigations having been carried out using classical polymorphisms and molecular markers. To better understand the genetic variability and the micro-evolutionary processes acting in human groups in the Brazilian Amazon region we used mitochondrial DNA to investigate 159 maternally unrelated individuals from five Amazonian African-descendant communities. The mitochondrial lineage distribution indicated a contribution of 50.2% from Africans (L0, L1, L2, and L3, 46.6% from Amerindians (haplogroups A, B, C and D and a small European contribution of 1.3%. These results indicated high genetic diversity in the Amerindian and African lineage groups, suggesting that the Brazilian Amazonian African-descendant populations reflect a possible population amalgamation of Amerindian women from different Amazonian indigenous tribes and African women from different geographic regions of Africa who had been brought to Brazil as slaves. The present study partially mapped the historical biological and social interactions that had occurred during the formation and expansion of Amazonian African-descendant communities.

    Irritable bowel syndrome (IBS) is a common functional gastrointestinal disorder. While abdominal pain is a dominant symptom of IBS, many sufferers also report widespread hypersensitivity and present with other chronic pain conditions. The presence of widespread hypersensitivity and extra-intestinal pain conditions suggests central nervous dysfunction. While central nervous system dysfunction may involve the spinal cord (central sensitisation) and brain, this review will focus on one brain mechanism, descending pain modulation. We will conduct a comprehensive search for the articles indexed in the databases Ovid MEDLINE, Ovid Embase, Ovid PsycINFO and Cochrane Central Register of Controlled Trial (CENTRAL) from their inception to August 2015, that report on any aspect of descending pain modulation in irritable bowel syndrome. Two independent reviewers will screen studies for eligibility, assess risk of bias and extract relevant data. Results will be tabulated and, if possible, a meta-analysis will be carried out. The systematic review outlined in this protocol aims to summarise current knowledge regarding descending pain modulation in IBS. PROSPERO CRD42015024284.

    This report of French 'Habilitation a diriger les recherches' summarizes my scientific activity from 1993 to 2003. During this decade, my research work was related to two particle physics experiments: CPLEAR and BABAR. The first one, CPLEAR, has recorded data from 1988 to 1995 on the low energy anti-proton ring (LEAR) at CERN. This experiment was devoted to the study of T, CPT et CP discrete symmetries. The second experiment, BABAR, has been running since 1999, on the PEP-II B factory at SLAC. This experiment searches for CP violation and tests the Standard Model through the measurements of the angles and the sides of the Unitarity Triangle. My research work is divided in five main topics: Study of CP and CPT violation in K{sup 0} {yields} {pi}{sup +} {pi}{sup -} decays; Performance optimization of the particle identification detector (DIRC) of the BABAR experiment; B meson tagging in BABAR experiment; {delta}m{sub d} measurement and Search for CP and T violation in mixing with dilepton events; Search for CP violation in B{sup 0} {yields} {rho}{sup {+-}} {pi}{sup {+-}} and B{sup 0} {yields} {pi}{sup {+-}} K{sup {+-}} decays.

    2016-01-01

    Following spinal cord injury (SCI) in the lamprey, there is virtually complete recovery of locomotion within a few weeks, but interestingly, axonal regeneration of reticulospinal (RS) neurons is mostly limited to short distances caudal to the injury site. To explain this situation, we hypothesize that descending propriospinal (PS) neurons relay descending drive from RS neurons to indirectly activate spinal central pattern generators (CPGs). In the present study, the contributions of PS neurons to locomotor recovery were tested in the lamprey following SCI. First, long RS neuron projections were interrupted by staggered spinal hemitransections on the right side at 10% body length (BL; normalized from the tip of the oral hood) and on the left side at 30% BL. For acute recovery conditions (≤1 wk) and before axonal regeneration, swimming muscle burst activity was relatively normal, but with some deficits in coordination. Second, lampreys received two spaced complete spinal transections, one at 10% BL and one at 30% BL, to interrupt long-axon RS neuron projections. At short recovery times (3–5 wk), RS and PS neurons will have regenerated their axons for short distances and potentially established a polysynaptic descending command pathway. At these short recovery times, swimming muscle burst activity had only minor coordination deficits. A computer model that incorporated either of the two spinal lesions could mimic many aspects of the experimental data. In conclusion, descending PS neurons are a viable mechanism for indirect activation of spinal locomotor CPGs, although there can be coordination deficits of locomotor activity. NEW & NOTEWORTHY In the lamprey following spinal lesion-mediated interruption of long axonal projections of reticulospinal (RS) neurons, sensory stimulation still elicited relatively normal locomotor muscle burst activity, but with some coordination deficits.

    Full Text Available La transmission de la mémoire migratoire est un processus difficile à cerner et il l’est d’autant plus en milieu maghrébin. Ceci tout d’abord, parce que cette mémoire renferme une expérience de l’exil complexe et parfois douloureuse. Ensuite, le fonctionnement de la famille immigrée et les relations existantes entre les parents porteurs de mémoire et les descendants héritiers de celle-ci créent des conditions de transferts mémoriels originales. Malgré cela, l’histoire migratoire circule, se diffuse, dans des conditions parfois compromises mais jamais impossibles; et la mémoire migratoire (reconstruite est alors une mémoire référentielle et participe ainsi à la reproduction des manières d’être plus qu’à la survivance d’un récit des origines. Incomplets, fragmentaires, les souvenirs permettent aussi d’engager une démarche de réflexivité sur le passé, de mieux appréhender le présent et de ne pas reproduire les erreurs d’hier. Alors que la France s’est engagée récemment dans un bouillonnement mémoriel autour du passé colonial, le discours des descendants d’immigrés maghrébins montrent effectivement que si l’histoire migratoire connaît quelques difficultés à se reconstruire et se transmettre, elle existe et ses effets traumatiques ne sont pas systématiques. Les individus récepteurs de cette mémoire en appellent davantage à une reconnaissance publique de la mémoire migratoire afin de ne pas reproduire la relégation, l’exclusion et le racisme vécus par les parents.In North African families, the process of passing down “migration memories” from one generation to another is rather difficult to discern in view of a lack of consistency in such aspects as the actual content of those memories (which is not particular to people from the Maghreb, the functioning of North African families, and the existing relations between those who carry the memories and those who inherit them.

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

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

    2017-01-01

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

    2018-02-01

    Full Text Available Descend technique and performance vary among elite racing cyclists and it is not clear what slower riders should do to improve their performance. An observation study was performed of the descending technique of members of a World Tour cycling team and the technique of each member was compared with the fastest descender amongst them. The obtained data gives us guidelines for rider specific feedback in order to improve his performance. The bicycles were equipped with a system that could measure: velocity, cadence, pedal power, position, steer angle, 3D orientation, rotational speeds and linear accelerations of the rear frame and brake force front and rear. From our observation study, the brake point and apex position turned out to be distinctive indicators of a fast cornering technique in a descent for a tight, hairpin corner. These two indicators can be used as feedback for a slower rider to improve his descend performance.

  18. The Role of Cannabinoid Receptors in the Descending Modulation of Pain

    Directory of Open Access Journals (Sweden)

    Francesco Rossi

    2010-08-01

    Full Text Available The endogenous antinociceptive descending pathway represents a circuitry of the supraspinal central nervous system whose task is to counteract pain. It includes the periaqueductal grey (PAG-rostral ventromedial medulla (RVM-dorsal horn (DH axis, which is the best characterized pain modulation system through which pain is endogenously inhibited. Thus, an alternative rational strategy for silencing pain is the activation of this anatomical substrate. Evidence of the involvement of cannabinoid receptors (CB in the supraspinal modulation of pain can be found in several studies in which intra-cerebral microinjections of cannabinoid ligands or positive modulators have proved to be analgesic in different pain models, whereas cannabinoid receptor antagonists or antisense nucleotides towards CB1 receptors have facilitated pain. Like opioids, cannabinoids produce centrally-mediated analgesia by activating a descending pathway which includes PAG and its projection to downstream RVM neurons, which in turn send inhibitory projections to the dorsal horn of the spinal cord. Indeed, several studies underline a supraspinal regulation of cannabinoids on g-aminobutyric acid (GABA and glutamate release which inhibit and enhance the antinociceptive descending pathway, respectively. Cannabinoid receptor activation expressed on presynaptic GABAergic terminals reduces the probability of neurotransmitter release thus dis-inhibiting the PAG-RVM-dorsal horn antinociceptive pathway. Cannabinoids seem to increase glutamate release (maybe as consequence of GABA decrease and to require glutamate receptor activation to induce antinociception. The consequent outcome is behavioral analgesia, which is reproduced in several pain conditions, from acute to chronic pain models such as inflammatory and neuropathic pain. Taken together these findings would suggest that supraspinal cannabinoid receptors have broad applications, from pain control to closely related central nervous system

  19. Bilateral descending hypothalamic projections to the spinal trigeminal nucleus caudalis in rats.

    Directory of Open Access Journals (Sweden)

    Khaled Abdallah

    Full Text Available Several lines of evidence suggest that the hypothalamus is involved in trigeminal pain processing. However, the organization of descending hypothalamic projections to the spinal trigeminal nucleus caudalis (Sp5C remains poorly understood. Microinjections of the retrograde tracer, fluorogold (FG, into the Sp5C, in rats, reveal that five hypothalamic nuclei project to the Sp5C: the paraventricular nucleus, the lateral hypothalamic area, the perifornical hypothalamic area, the A11 nucleus and the retrochiasmatic area. Descending hypothalamic projections to the Sp5C are bilateral, except those from the paraventricular nucleus which exhibit a clear ipsilateral predominance. Moreover, the density of retrogradely FG-labeled neurons in the hypothalamus varies according to the dorso-ventral localization of the Sp5C injection site. There are much more labeled neurons after injections into the ventrolateral part of the Sp5C (where ophthalmic afferents project than after injections into its dorsomedial or intermediate parts (where mandibular and maxillary afferents, respectively, project. These results demonstrate that the organization of descending hypothalamic projections to the spinal dorsal horn and Sp5C are different. Whereas the former are ipsilateral, the latter are bilateral. Moreover, hypothalamic projections to the Sp5C display somatotopy, suggesting that these projections are preferentially involved in the processing of meningeal and cutaneous inputs from the ophthalmic branch of the trigeminal nerve in rats. Therefore, our results suggest that the control of trigeminal and spinal dorsal horn processing of nociceptive information by hypothalamic neurons is different and raise the question of the role of bilateral, rather than unilateral, hypothalamic control.

    2012-01-01

    Full Text Available The mortality rate from descending necrotising mediastinitis (DNM has declined since its first description in 1938. The decline in mortality has been attributed to earlier diagnosis by way of contrast-enhanced computed tomographic (CT scanning and aggressive surgical intervention in the form of transthoracic drainage. We describe a case of DNM with involvement of anterior and posterior mediastinum down to the diaphragm, managed by cervicotomy and transverse cervical drainage with placement of corrugated drains and a pleural chest drain, with a delayed mediastinoscopy and mediastinal drain placement. We advocate a conservative approach with limited debridement and emphasis on drainage of infection in line with published case series.

  2. Descending serotonergic facilitation and the antinociceptive effects of pregabalin in a rat model of osteoarthritic pain

    2009-08-01

    Full Text Available Abstract Background Descending facilitation, from the brainstem, promotes spinal neuronal hyperexcitability and behavioural hypersensitivity in many chronic pain states. We have previously demonstrated enhanced descending facilitation onto dorsal horn neurones in a neuropathic pain model, and shown this to enable the analgesic effectiveness of gabapentin. Here we have tested if this hypothesis applies to other pain states by using a combination of approaches in a rat model of osteoarthritis (OA to ascertain if 1 a role for descending 5HT mediated facilitation exists, and 2 if pregabalin (a newer analogue of gabapentin is an effective antinociceptive agent in this model. Further, quantitative-PCR experiments were undertaken to analyse the α2δ-1 and 5-HT3A subunit mRNA levels in L3–6 DRG in order to assess whether changes in these molecular substrates have a bearing on the pharmacological effects of ondansetron and pregabalin in OA. Results Osteoarthritis was induced via intra-articular injection of monosodium iodoacetate (MIA into the knee joint. Control animals were injected with 0.9% saline. Two weeks later in vivo electrophysiology was performed, comparing the effects of spinal ondansetron (10–100 μg/50 μl or systemic pregabalin (0.3 – 10 mg/kg on evoked responses of dorsal horn neurones to electrical, mechanical and thermal stimuli in MIA or control rats. In MIA rats, ondansetron significantly inhibited the evoked responses to both innocuous and noxious natural evoked neuronal responses, whereas only inhibition of noxious evoked responses was seen in controls. Pregabalin significantly inhibited neuronal responses in the MIA rats only; this effect was blocked by a pre-administration of spinal ondansetron. Analysis of α2δ-1 and 5-HT3A subunit mRNA levels in L3–6 DRG revealed a significant increase in α2δ-1 levels in ipsilateral L3&4 DRG in MIA rats. 5-HT3A subunit mRNA levels were unchanged. Conclusion These data suggest

    Ancestor–descendant relationships (ADRs), involving descent with modification, are the fundamental concept in evolution, but are usually difficult to recognize. We examined the cladistic relationship between the only reported fossil pygmy right whale, †Miocaperea pulchra, and its sole living relative, the enigmatic pygmy right whale Caperea marginata, the latter represented by both adult and juvenile specimens. †Miocaperea is phylogenetically bracketed between juvenile and adult Caperea marginata in morphologically based analyses, thus suggesting a possible ADR—the first so far identified within baleen whales (Cetacea: Mysticeti). The †Miocaperea–Caperea lineage may show long-term morphological stasis and, in turn, punctuated equilibrium. PMID:25589485

    This paper presents a novel interactive system that provides users with virtual reality (VR) experiences, wherein users feel as if they are ascending/descending stairs through passive haptic feedback. The passive haptic stimuli are provided by small bumps under the feet of users; these stimuli are provided to represent the edges of the stairs in the virtual environment. The visual stimuli of the stairs and shoes, provided by head-mounted displays, evoke a visuo-haptic interaction that modifies a user's perception of the floor shape. Our system enables users to experience all types of stairs, such as half-turn and spiral stairs, in a VR setting. We conducted a preliminary user study and two experiments to evaluate the proposed technique. The preliminary user study investigated the effectiveness of the basic idea associated with the proposed technique for the case of a user ascending stairs. The results demonstrated that the passive haptic feedback produced by the small bumps enhanced the user's feeling of presence and sense of ascending. We subsequently performed an experiment to investigate an improved viewpoint manipulation method and the interaction of the manipulation and haptics for both the ascending and descending cases. The experimental results demonstrated that the participants had a feeling of presence and felt a steep stair gradient under the condition of haptic feedback and viewpoint manipulation based on the characteristics of actual stair walking data. However, these results also indicated that the proposed system may not be as effective in providing a sense of descending stairs without an optimization of the haptic stimuli. We then redesigned the shape of the small bumps, and evaluated the design in a second experiment. The results indicated that the best shape to present haptic stimuli is a right triangle cross section in both the ascending and descending cases. Although it is necessary to install small protrusions in the determined direction, by

    Th effectiveness of selection for high and low body weight at six weeks of age was studied in descendants of x-irradiated (R) and nonirradiated (C) inbred rats. There were two replicates of each of the direction of selection--irradiation treatments. In C lines, there were no consistent responses to selection, probably due to a low level of genetic variability. In R rats, selection was effective only for decreased body weight. The results of this experiment do not suggest the use of irradiation combined with selection as a means of enhancing responses to selection in animals

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

    1998-01-01

    Purpose: To present four cases of penetrating ulcer of the descending thoracic aorta treated by transfemoral insertion of an endoluminal stent-graft. Methods: Four patients with penetrating aortic ulcers were reviewed. Three cases were complicated by rupture, false aneurysm, or retrograde dissection. All patients were treated by endovascular stent-graft and were followed by helical computed tomography (CT). Results: Endovascular stent-graft deployment was successful in all patients. However, in one case we observed a perigraft leak that spontaneously disappeared within the first month, and two interventions were needed for another patient. Following treatment, one episode of transient spinal ischemia was observed. The 30-day survival rate was 100%, but one patient died from pneumonia with cardiac failure 34 days after the procedure. In one patient, helical CT performed at 3 months showed a false aneurysm independent of the first ulcer. This patient refused any further treatment and suddenly died at home (unknown cause) after a 6-month follow-up period. Conclusion: Transluminal placement of endovascular stent-grafts for treatment of penetrating ulcers of the descending thoracic aorta appears to be a possible alternative to classical surgery. After treatment, follow-up by CT is essential to detect possible complications of the disease

  11. Math modeling for helicopter simulation of low speed, low altitude and steeply descending flight

    1982-01-01

    A math model was formulated to represent some of the aerodynamic effects of low speed, low altitude, and steeply descending flight. The formulation is intended to be consistent with the single rotor real time simulation model at NASA Ames Research Center. The effect of low speed, low altitude flight on main rotor downwash was obtained by assuming a uniform plus first harmonic inflow model and then by using wind tunnel data in the form of hub loads to solve for the inflow coefficients. The result was a set of tables for steady and first harmonic inflow coefficients as functions of ground proximity, angle of attack, and airspeed. The aerodynamics associated with steep descending flight in the vortex ring state were modeled by replacing the steady induced downwash derived from momentum theory with an experimentally derived value and by including a thrust fluctuations effect due to vortex shedding. Tables of the induced downwash and the magnitude of the thrust fluctuations were created as functions of angle of attack and airspeed.

    2018-03-01

    Full Text Available Summary:. Volume loss is 1 of the major factors influencing cosmetic outcomes of breast after partial mastectomy (PM, especially for smaller breasts, and therefore, volume replacement is critical for optimizing the final aesthetic outcome. We present a novel technique of raising a pedicled descending branch latissimus dorsi (LD mini-flap for reconstruction of PM defects via an axillary incision. After PM, the LD mini-flap is harvested through the existing axillary incision of the axillary dissection or the sentinel lymph node biopsy. The descending branches of thoracodorsal vessels and nerve are carefully identified and isolated. The transverse branches are protected to maintain muscle innervation and function. The LD muscle is then undermined posteriorly and inferiorly to create a submuscular pocket and a subcutaneous pocket between LD muscle and superficial fascia. Once the submuscular plane is created, the muscle is divided along the muscle fibers from the deep surface including a layer of fat above the muscle. Finally, the LD mini-flap is transferred to the breast defect. Given the limited length and mobility of the LD mini-flap, this approach is best utilized for lateral breast defects. However, for medial defects, the lateral breast tissue is rearranged to reconstruct the medial breast defect, and an LD mini-flap is then used to reconstruct the lateral breast donor site. This technique can therefore be employed to reconstruct all quadrants of the breast and can provide aesthetic outcomes without scars on the back, with minimal dysfunction of LD muscle.

    The purpose of this study is to verify the usefulness of the quantification of aortic wall involvement by enhanced computed tomography (CT). One-hundred thirteen Japanese patients underwent two enhanced CT of the descending thoracic aorta at intervals. We sliced the descending thoracic aorta continuously from the level of the tracheal bifurcation with 1 cm intervals, and we defined aortic wall volume (AWV) (cm 3 ) as the sum of a 7-slice area of aortic wall involving calcification. The average of AWV increased from 7.95±2.92 cm 3 to 8.70±2.98 cm 3 . The developmental rate of AWV (ΔAWV) was 0.270±0.281 cm 3 /year. ΔAWV did not have a significant correlation with any risk factor at the baseline. ΔAWV had significant correlation with total cholesterol, (LDL-C) low-density lipoprotein cholesterol and LDL-C/(HDL-C) high-density lipoprotein cholesterol ratio at the follow-up, and by multivariate analysis with only the LDL-C/HDL-C ratio. ΔAWV was not correlated with the intake status of hypoglycemic, antihypertensive or lipid-lowering drugs. The cut-off level of total cholesterol with the most significant odds ratio for progression of aortic wall was 190 mg/dl, and that of LDL-C was 130 mg/dl. This method proved to be useful for the non-invasive assessment of aortic wall thickness. (author)

    Full Text Available Knee osteoarthritis (KOA is a highly prevalent, chronic joint disorder, which can lead to chronic pain. Although electroacupuncture (EA is effective in relieving chronic pain in the clinic, the involved mechanisms remain unclear. Reduced diffuse noxius inhibitory controls (DNIC function is associated with chronic pain and may be related to the action of endocannabinoids. In the present study, we determined whether EA may potentiate cannabinoid receptor-mediated descending inhibitory control and inhibit chronic pain in a mouse model of KOA. We found that the optimized parameters of EA inhibiting chronic pain were the low frequency and high intensity (2 Hz + 1 mA. EA reversed the reduced expression of CB1 receptors and the 2-arachidonoylglycerol (2-AG level in the midbrain in chronic pain. Microinjection of the CB1 receptor antagonist AM251 into the ventrolateral periaqueductal gray (vlPAG can reversed the EA effect on pain hypersensitivity and DNIC function. In addition, CB1 receptors on GABAergic but not glutamatergic neurons are involved in the EA effect on DNIC function and descending inhibitory control of 5-HT in the medulla, thus inhibiting chronic pain. Our data suggest that endocannabinoid (2-AG-CB1R-GABA-5-HT may be a novel signaling pathway involved in the effect of EA improving DNIC function and inhibiting chronic pain.

    Full Text Available The Nigrostriatal pathway (NSP is formed by dopaminergic axons that project from the ventral midbrain to the dorsolateral striatum as part of the medial forebrain bundle. Previous studies have implicated chemotropic proteins in the formation of the NSP during development but little is known of the role of substrate-anchored signals in this process. We observed in mouse and rat embryos that midbrain dopaminergic axons ascend in close apposition to descending GAD65-positive axon bundles throughout their trajectory to the striatum. To test whether such interaction is important for dopaminergic axon pathfinding, we analyzed transgenic mouse embryos in which the GAD65 axon bundle was reduced by the conditional expression of the diphtheria toxin. In these embryos we observed dopaminergic misprojection into the hypothalamic region and abnormal projection in the striatum. In addition, analysis of Robo1/2 and Slit1/2 knockout embryos revealed that the previously described dopaminergic misprojection in these embryos is accompanied by severe alterations in the GAD65 axon scaffold. Additional studies with cultured dopaminergic neurons and whole embryos suggest that NCAM and Robo proteins are involved in the interaction of GAD65 and dopaminergic axons. These results indicate that the fasciculation between descending GAD65 axon bundles and ascending dopaminergic axons is required for the stereotypical NSP formation during brain development and that known guidance cues may determine this projection indirectly by instructing the pathfinding of the axons that are part of the GAD65 axon scaffold.

  16. D’une convergence remarquable entre phénoménologie et philosophie analytique: la lecture ricœurienne des thèses de Sartre et Ryle sur l’imagination

    Full Text Available The aim of this article is to analyse the meaning and the implications of the comparative interpretation of Sartre’s and Ryle’s theses on imagination that Ricœur undertook in the still unpublished text of his Lectures on Imagination. These lectures were delivered at the University of Chicago in 1975. First, the article shows how Ricœur brings out a strong convergence, both in the method and in the presuppositions, of the Sartrean and Rylean conceptions of imagination : the choice of a descriptive method leads the two philosophers to a common critique of the mental image. Secondly, the article analyses the properly critical side of the Ricœurian interpretation by showing how it eventually brings to light the common theoretical limitation of Sartre’s and Ryle’s theses on imagination. According to Ricœur, those theses lead to a conception of image as picture and fail to consider the image as fiction, and so they remain locked in a theory of reproductive imagination and of the primacy of perception.RésuméCet article se propose d’analyser le sens et les enjeux de la lecture croisée des thèses de Sartre et Ryle sur l’imagination à laquelle se livre Ricœur dans le texte encore inédit des Lectures on imagination professées en 1975 à l’Université de Chicago. Dans un premier temps, il montre comment Ricœur met en relief une convergence forte, de méthode et de présupposés entre les conceptions sartrienne et rylienne de l’imagination : le choix d’une méthode  descriptive conduisant les deux philosophes à une commune critique de l’image mentale. Puis, dans un second temps, il analyse le versant proprement critique de la lecture ricœurienne en montrant comment elle en vient à dénoncer une commune limitation théorique des thèses de Sartre et Ryle sur l’imagination. Selon Ricœur, ces thèses débouchent sur une conception de l’image comme tableau qui échoue à penser l’image comme fiction et elles restent

  17. Les AOC dans la mondialisation

    Full Text Available Fruit du conflit plusieurs fois séculaire entre les producteurs et le négoce, le terroir vitivinicole est né de phénomènes de « distinction » qui en Bordelais donnent les « crus ». Ces terroirs de production identifiés, il fallut les faire durer, face à conjoncture, face au négoce. Les réussites les plus nettes sont le résultat d’un projet collectif dont l’AOC à la française est l’une des plus spectaculaires. Renforcer le terroir, compris comme un espace de production géré par les producteurs, devient alors une des conditions essentielles de la durabilité du système. L’avenir des AOC réside sans doute dans une meilleure gestion du conflit négoce/production par l’interprofession mais aussi (surtout ! dans un renforcement de la gestion de la production au sein de l’aire de production qu’est le terroir. L’avenir du terroir relève de la gouvernance de cette aire de production avec trois partenaires : la puissance publique (INAO, l’interprofession et le syndicat des producteurs. Se pose dès lors la question du partage des compétences et la durabilité des AOC paraît liée en grande partie à une définition claire du rôle et donc du statut des syndicats de producteurs, à une véritable gouvernance locale, seule capable de donner du sens à l’ancrage géographique des vins dits de « terroir ». Mais alors ne faut-il pas impliquer un troisième partenaire, la société locale toute entière à travers ses représentations démocratique et associative ?Resulting from century-long conflicts between producers and merchants, vineyards have developped out of "distinction" phenomenons which in the Bordeaux region gave birth to "crus" (vintages. Such identified terroirs had to be defended: the French collective AOC (Denomination of Origin project is one of the most spectacular success.

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

    Full Text Available L'hybridation interspécifique entre le saumon atlantique et la truite commune dans la nature a été mise en évidence dans différents pays d'Europe et au Canada. Une étude a été entreprise pour examiner son incidence dans des populations de salmonidés de certaines rivières des Asturies (nord de l'Espagne et du sud-ouest de la France. Elle a été complétée par des expériences en milieu contrôlé pour déterminer les causes et les conditions de la disparition des barrières comportementales permettant le maintien de l'isolement reproducteur. Les hypothèses de travail étaient que l'hybridation pouvait être favorisée par le comportement de «sneaker» des tacons mâles précoces et par les repeuplements en juvéniles des deux espèces. Les résultats obtenus confirment que l'hybridation entre la truite et le saumon est un phénomène répandu, qui peut affecter localement des fractions significatives des populations (9,4 % sur la rivière Narcea dans les Asturies. Dans l'aire originelle de distribution des deux espèces, le croisement s'effectue dans le sens femelle saumon x mâle truite. Dans les conditions normales de sympatrie, les barrières d'isolement reproducteur pré-appariement paraissent solides en raison du comportement agressif du mâle conspécifique dominant qui parvient à écarter efficacement les mâles compétiteurs hétérospécifiques. En l'absence de mâle conspécifique, l'hybridation peut avoir lieu. Cependant, les femelles modifient leur comportement, ralentissent leur activité de frai et le succès reproducteur, particulièrement chez la truite, diminue. Par ailleurs, les hypothèses de travail ne sont pas vérifiées. Pour éviter l'hybridation, il est recommandé au gestionnaire de veiller à la qualité et à la quantité des zones de reproduction, de maintenir l'équilibre des populations de géniteurs et de limiter les repeuplements en sujets non autochtones.

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

    Full Text Available 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. Bir kelimedeki seslerden birinin, çeşitli nedenlerle düşmesine ses düşmesi denir. Ses düşmesi üç çeşittir: ön ses düşmesi, iç ses düşmesi ve son ses düşmesi. Son ses düşmesi, kelimede son ses durumunda olan ünlü veya ünsüzün düşmesidir. Bu durum, bütün lehçelerde ve ağızlarda standart değildir. Düşen bazı sesler, belli bir bölge içinde yoğunlaşırken, bazı bölgelerde görülmemekte ve hatta birkaç ya da bir örnekle sınırlı kalabilmektedir. Bu daha çok ağızlarda görülür. Çalışmada, Türkiye Türkçesinde ve Çağdaş Türk Lehçelerinde alıntı kelimelerde son ses düşmesi bahsi örnekleriyle ele alınacaktır.

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

    We report the case of an acute proximal occlusion of the left anterior descending coronary (LAD) artery following a scuba diving decompression accident and associated with normal ECG. Following uneventful thromboaspiration and coronary stenting, the patient was discharged on day  4 with secondary preventative therapies. A transthoracic echocardiography performed at this point showed a complete recovery compared with an initial localised akinesia involving the anterior and apical portion of the left ventricle upon admission. This case highlights that significant acute coronary lesions involving the LAD can occur without any ECG anomaly. The presence of acute and persistent angina associated with troponin elevation should prompt physicians to consider coronary angiography without delay, independently of the ECG results.

    Full Text Available Descending necrotizing mediastinitis (DNM is a rare condition in which oropharyngeal infection spreads to the mediastinum via the cervical fascia. Delayed diagnosis and surgery result in a high mortality rate among patients with DNM. We present a case of DNM resulting from odontogenic infection treated successfully with tooth extraction following mediastinal and cervical drainage. A 43-year-old, previously healthy Japanese man was admitted to our hospital for treatment of acute mediastinitis. Computed tomography revealed gas collection around the mid-thoracic esophagus and bilateral pleural effusion. We performed mediastinal drainage via right thoracotomy. Cervicotomy was performed on postoperative day 14 to drain a residual cervical abscess. The patient required the extraction of ten teeth over three procedures to address primary odontogenic infection before his fever resolved on postoperative day 40. Prompt diagnosis, aggressive drainage and removal of the source of infection can improve survival among patients with this life-threatening disease.

    Colostomy irrigation (CI) is the regular irrigation of the bowel for persons with a permanent colostomy of the descending or sigmoid colon. Although this technique was first described in the 1920s, a recent study of 985 WOC nurses found that almost half (47%) do not routinely teach CI to persons with colostomies. In a systematic review (Evidence-Based Report Card) published in this issue of the Journal, we summarized current best evidence concerning the effect of CI on bowel function and found that irrigation reduces the frequency of bowel elimination episodes and allows some patients to reduce or eliminate ongoing use of a pouching system. This article describes techniques for teaching CI and discussed additional findings associated with CI.

    Ancestor-descendant relationships (ADRs), involving descent with modification, are the fundamental concept in evolution, but are usually difficult to recognize. We examined the cladistic relationship between the only reported fossil pygmy right whale, †Miocaperea pulchra, and its sole living relative, the enigmatic pygmy right whale Caperea marginata, the latter represented by both adult and juvenile specimens. †Miocaperea is phylogenetically bracketed between juvenile and adult Caperea marginata in morphologically based analyses, thus suggesting a possible ADR-the first so far identified within baleen whales (Cetacea: Mysticeti). The †Miocaperea-Caperea lineage may show long-term morphological stasis and, in turn, punctuated equilibrium. © 2015 The Author(s) Published by the Royal Society. All rights reserved.

    2011-07-01

    Descending bilateral control of external oblique (EO) and latissimus dorsi (LD) was investigated using transcranial magnetic stimulation. Contralateral (CL) motor evoked potential (MEP) thresholds were lower and latencies were shorter than for ipsilateral (IL) MEPs. Hotspots for EO were symmetrical; this was not the case for LD. The volumes of drive to the left and right muscles were not different. The laterality index was not different between the left and right muscles. The average index for the EO muscles was closer to zero than that for LD, suggesting a stronger IL drive to EO. The symmetry of drive to each muscle did not differ; however, the symmetry of drive varies within a subject for different muscles and between subjects for the same muscle. The findings may be useful in understanding a number of clinical conditions relating to the trunk and also for predicting the outcome of rehabilitative strategies.

    Full Text Available Background: In Paraguay, little is known about the Afro-descendant population. It is important to know about their nutritional status, mainly in childhood, to guide appropriate action. Objective: To determine the nutritional profile of children under five years from the African descendants’ communities in Paraguay and its associated factors. Material and methods: A cross-sectional and observational design with analytical component was developed. It involved healthy male and female children under five years old, with at least one African descendant as immediate family. Dietary habits and nutritional status (WHO criteria were assessed. WHO Anthro and SPSS 16.0 software were used. Results: 150 children were included. The median of age was 26.9 months (1.2-59.9 m, and 50.7% were males. The median maternal age was 28.3 years (16-49 years. Children with Exclusive Breast Feeding (EBF, n=119 had a mean duration of 3.5±1.8 months (1-7m. 26.9% were exclusively breastfed during six months.

Children with UW had a lower average of age of onset of complementary feeding (1.7 vs 4.9 months, p˂0.0001 compare with their pairs without malnutrition. Conclusion: Chronic malnutrition was the most prevalent chronic disease affecting over 1 in 10 children. Early initiation of complementary feeding could be a risk factor for malnutrition.

  15. Fertility among descendants of immigrants in Belgium: The role of the partner

    2017-06-01

    Full Text Available Background: Research on the fertility behavior of descendants of immigrants has focused on female characteristics and has largely neglected those of the male partner. One key aspect is whether the partner is of same (endogamous or of different (exogamous ethnic origin. Moreover, the male partner may be born in the same country as the female partner, or he may have migrated to that country later in the life course. Consequently, both his ethnic origin and migration history may affect the fertility behavior of second-generation women. Objective: This study analyzes to what extent second and higher order births of second-generation women of Southern European, Turkish, or Moroccan origin in Belgium differ by the ethnic origin and migration history of the male partner. Methods: We apply event history methods using the 2001 Belgian Census, linked with the 2006 Belgian National Population Register. Results: Women of Turkish and Moroccan origin in an endogamous union experience higher second and subsequent birth rates than their counterparts in an exogamous union. However, no variation is found within the endogamous unions: Whether or not the endogamous partner has been born in the country of origin does not seem to affect second and higher order birth rates. For women of Southern European origin, second and higher order birth rates do not differ by origin and generation of their partner. Contribution: This study extends the literature on the fertility behavior of the descendants of immigrants by demonstrating the importance of male partner characteristics in explaining the transition to a second or a higher order birth.

  16. Descending projections from the dysgranular zone of rat primary somatosensory cortex processing deep somatic input.

    Lee, Taehee; Kim, Uhnoh

    2012-04-01

    In the mammalian somatic system, peripheral inputs from cutaneous and deep receptors ascend via different subcortical channels and terminate in largely separate regions of the primary somatosensory cortex (SI). How these inputs are processed in SI and then projected back to the subcortical relay centers is critical for understanding how SI may regulate somatic information processing in the subcortex. Although it is now relatively well understood how SI cutaneous areas project to the subcortical structures, little is known about the descending projections from SI areas processing deep somatic input. We examined this issue by using the rodent somatic system as a model. In rat SI, deep somatic input is processed mainly in the dysgranular zone (DSZ) enclosed by the cutaneous barrel subfields. By using biotinylated dextran amine (BDA) as anterograde tracer, we characterized the topography of corticostriatal and corticofugal projections arising in the DSZ. The DSZ projections terminate mainly in the lateral subregions of the striatum that are also known as the target of certain SI cutaneous areas. This suggests that SI processing of deep and cutaneous information may be integrated, to a certain degree, in this striatal region. By contrast, at both thalamic and prethalamic levels as far as the spinal cord, descending projections from DSZ terminate in areas largely distinguishable from those that receive input from SI cutaneous areas. These subcortical targets of DSZ include not only the sensory but also motor-related structures, suggesting that SI processing of deep input may engage in regulating somatic and motor information flow between the cortex and periphery.

    In the inner medulla, radial organization of nephrons and blood vessels around collecting duct (CD) clusters leads to two lateral interstitial regions and preferential intersegmental fluid and solute flows. As the descending (DTLs) and ascending thin limbs (ATLs) pass through these regions, their transepithelial fluid and solute flows are influenced by variable transepithelial solute gradients and structure-to-structure interactions. The goal of this study was to quantify structure-to-structure interactions, so as to better understand compartmentation and flows of transepithelial water, NaCl, and urea and generation of the axial osmotic gradient. To accomplish this, we determined lateral distances of AQP1-positive and AQP1-negative DTLs and ATLs from their nearest CDs, so as to gauge interactions with intercluster and intracluster lateral regions and interactions with interstitial nodal spaces (INSs). DTLs express reduced AQP1 and low transepithelial water permeability along their deepest segments. Deep AQP1-null segments, prebend segments, and ATLs lie equally near to CDs. Prebend segments and ATLs abut CDs and INSs throughout much of their descent and ascent, respectively; however, the distal 30% of ATLs of the longest loops lie distant from CDs as they approach the outer medullary boundary and have minimal interaction with INSs. These relationships occur regardless of loop length. Finally, we show that ascending vasa recta separate intercluster AQP1-positive DTLs from descending vasa recta, thereby minimizing dilution of gradients that drive solute secretion. We hypothesize that DTLs and ATLs enter and exit CD clusters in an orchestrated fashion that is important for generation of the corticopapillary solute gradient by minimizing NaCl and urea loss.

    Full Text Available Sejak tragedi pemboman WTC tanggal 11 September 2001 yang disusul dengan rangkaian peledakan bom di sejumlah negara, banyak orang non Muslim yang berasumsi bahwa ajaran Islam identik dengan radikalisme. Walaupun assumsi yang berkembang itu dapat dimaklumi, namun keyakinan tersebut tentu saja tidak sepenuhnya benar. Karena meskipun terdapat sekelompok orang Islam yang berbuat radikal, akan tetapi mayoritas Muslim justru bertentangan dengan mereka. Lagi pula, jika dicermati secara mendalam, sesungguhnya Islam sama sekali tidak mentolerir tindakan radikal. Ia adalah agama kasih sayang yang sangat mendodrong penganutnya untuk berbuat baik terhadap orang lain, termasuk kepada orang-orang non-Muslim. Artikel ini menawarkan beberapa upaya strategis dalam mengantisipasi dan menanggulangi bahaya radikalisme-terorisme.

La station thermale apparaît comme un eldorado où la fortune est à portée de la main. Cette fortune n’est pourtant pas si facile à obtenir, la gestion thermale est ingrate, et les centaines de villes d’eaux françaises ne peuvent pas toutes obtenir un succès comparable à celui de Vichy ou d’Aix-les-Bains.

    Full Text Available Travailler dans l’urgence est devenu un impératif catégorique pour nombre de salariés. Cet impératif se double d’une injonction paradoxale : il faut que le travail soit « vite fait, bien fait ». Comment la légitimation de l’urgence est-elle construite ? Dans quelle mesure les salariés intériorisent-ils cette logique managériale ? Quelles différences note-t-on suivant leur statut hiérarchique ? Cet article vise à rendre compte d’une enquête menée au sein d’un centre de maintenance d’une compagnie aérienne. Au-delà de l’observation des différentes formes que prend le travail dans l’urgence, ce sont les arrangements différenciés et marqués socialement entre les mécaniciens, d’un côté, et les managers de proximité, de l’autre, que nous analysons. Cela nous a conduit à repérer divers mécanismes de défense utilisés par les salariés ainsi qu’à discuter l’intérêt et les limites d’un dispositif original mis en place par la direction : un « bureau des pleurs managérial ».Working under pressure has become a categorical imperative for many employees, especially since it is generally coupled with the contradictory requirement that a quick job be done well. The question then becomes how time pressure is legitimised; to what extent employees internalise these managerial models; and whether their perceptions change depending on their hierarchical status. The article presents results from a research study carried out in an airline company’s maintenance centre. In addition to its analysis of the different forms of working under pressure, it also looks at how mechanics and their immediate managers adapt to this kind of regime, and whether any such differentiated arrangements vary along social lines. What appears are a number of defence mechanisms developed by employees. The discussion also covers the strengths and weaknesses of an unusual scheme set up by one company, involving a

  6. Semi-automated segmentation of the sigmoid and descending colon for radiotherapy planning using the fast marching method

    A fast and accurate segmentation of organs at risk, such as the healthy colon, would be of benefit for planning of radiotherapy, in particular in an adaptive scenario. For the treatment of pelvic tumours, a great challenge is the segmentation of the most adjacent and sensitive parts of the gastrointestinal tract, the sigmoid and descending colon. We propose a semi-automated method to segment these bowel parts using the fast marching (FM) method. Standard 3D computed tomography (CT) image data obtained from routine radiotherapy planning were used. Our pre-processing steps distinguish the intestine, muscles and air from connective tissue. The core part of our method separates the sigmoid and descending colon from the muscles and other segments of the intestine. This is done by utilizing the ability of the FM method to compute a specified minimal energy functional integrated along a path, and thereby extracting the colon centre line between user-defined control points in the sigmoid and descending colon. Further, we reconstruct the tube-shaped geometry of the sigmoid and descending colon by fitting ellipsoids to points on the path and by adding adjacent voxels that are likely voxels belonging to these bowel parts. Our results were compared to manually outlined sigmoid and descending colon, and evaluated using the Dice coefficient (DC). Tests on 11 patients gave an average DC of 0.83 (±0.07) with little user interaction. We conclude that the proposed method makes it possible to fast and accurately segment the sigmoid and descending colon from routine CT image data.

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

    a securite inherente. Toutefois, les systemes a securite non inherente restent nombreux dans les installations nucleaires et le recours a l'une ou l'autre des deux premieres methodes devient necessaire. Ces methodes sont liees a la gestion des matieres nucleaires. Dans les installations ou sont manipulees de petites quantites de matieres fissiles, il est souvent possible d'assurer la securite nucleaire en admettant dans chaque salle une masse de matiere fissile inferieure a la masse ciritique minimale. Pour des installations plus importantes, un tel controle, qui repose entierement sur la gestion des matieres, devient impossible. L'auteur examine, dans le cas particulier d'une usine oe traitement de combustibles irradies par voie aqueuse (les combustibles sont a base d'uranium naturel), comment se presente la liaison entre gestion et securite nucleaire. Une telle usine comprend grossierement trois parties au point de vue du controle de la criticite: Dans la premiere partie, traitant des solutions assez diluees, le controle qui s'impose est celui de la concentration. Si ce controle est aise (analyse et compteurs neutrons), il est difficile de s'assurer qu'il ne se forme pas de depots: bien que l'experience ait montre qu'ils n'etaient pas tellement a craindre, le fait bien connu d'un bilan matieres deficitaire reste un souci en matiere de criticite. Dans cette partie, la gestion des matieres, encore imparfaitement realisee, est de premiere importance pour la securite. La deuxieme partie traite des solutions concentrees et des precipites humides. C'est le domaine de la geometrie sure. La gestion des matieres l'interesse moins directement mais reste un facteur de securite important (en cas d'intervention, de nettoyage des appareils, etc.). Un controle par la masse s'impose dans la troisieme partie qui traite des produits secs. La gestion ne presente pas de difficulte particuliere. A ce schema se superpose une partie moins spectaculaire mais qui sur le plan surete est de

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

    Full Text Available Abstract Background Absorption of water and Na+ in descending colonic crypts is dependent on the barrier function of the surrounding myofibroblastic pericryptal sheath. Here the effects of high and low Na+ diets and exposure to whole body ionising radiation on the growth and activation of the descending colonic pericryptal myofibroblasts are evaluated. In addition the effect of a post-irradiation treatment with the angiotensin converting enzyme inhibitor Captopril was investigated. Methods The levels of Angiotensin II type 1 receptor (AT1, ACE, collagen type IV, transforming growth factor-β type 1 receptor (TGF-βR1, OB cadherin and α-smooth muscle actin in both descending colon and caecum were evaluated, using immunocytochemistry and confocal microscopy, in rats fed on high and low Na+ diets (LS. These parameters were also determined during 3 months post-irradiation with 8Gy from a 60Co source in the presence and absence of the angiotensin converting enzyme inhibitor, Captopril. Results Increases in AT1 receptor (135.6% ± 18.3, P Conclusions These results demonstrate an activation of descending colonic myofibroblasts to trophic stimuli, or irradiation, which can be attenuated by Captopril, indicative of local trophic control by angiotensin II and TGF-β release.

    Understanding the anatomy of the pterygomaxillary junction region helps prevent blood loss in Le Fort I osteotomy. Here, we determined the location of the descending palatine artery and the structure of the pterygomaxillary region. The study group consisted of 82 Japanese patients with mandibular prognathism and asymmetry, with and without maxillary retrognathism or asymmetry. A total of 164 sides were measured and divided into right versus left, men versus women, and bimaxillary osteotomy (B) versus mandibular osteotomy (S). Lateral and frontal cephalograms and computed tomography (CT) were analysed for all patients. The relationship between the cephalometric measurements and the measurements of the descending palatine artery and pterygoid plate (PP) were assessed. There were no significant correlations between measurements of cephalograms and those of the descending palatine artery and PPs. There were significant differences between right and left in lateral plate length (p=0.0014) and thickness of PP (p=0.0047). There were significant differences between men and women in right width of PP (p=0.0034), right thickness of PP (p=0.0063), left posterior length (p=0.0196), and left thickness of PP (p=0.0279). The B group had a shorter anterior length than the S group (right: ppalatine artery and the morphology of the PPs were not significantly associated with any cephalometric measurements. CT examination is necessary to recognize the anatomy of pterygomaxillary region and the exact positions of descending palatine artery before Le Fort I osteotomy.

    The role of laparoscopic surgery in management of transverse and descending colon cancer remains controversial. The aim of the present study is to investigate the short-term and oncologic long-term outcomes associated with laparoscopic surgery for transverse and descending colon cancer. This cohort study analyzed 245 patients (stage II disease, n = 70; stage III disease, n = 63) who underwent resection of transverse and descending colon cancers, including 200 laparoscopic surgeries (LAC) and 45 conventional open surgeries (OC) from December 1996 to December 2010. Short-term and oncologic long-term outcomes were recorded. The operative time was longer in the LAC group than in the OC group. However, intraoperative blood loss was significantly lower and postoperative recovery time was significantly shorter in the LAC group than in the OC group. The 5-year overall and disease-free survival rates for patients with stage II were 84.9% and 84.9% in the OC group and 93.7% and 90.0% in the LAC group, respectively. The 5-year overall and disease-free survival rates for patients with stage III disease were 63.4% and 54.6% in the OC group and 66.7% and 56.9% in the LAC group, respectively. Use of laparoscopic surgery resulted in acceptable short-term and oncologic outcomes in patients with advanced transverse and descending colon cancer.

    2010-01-01

    We have recently reported the importance of spinal rapamycin-sensitive pathways in maintaining persistent pain-like states. A descending facilitatory drive mediated through spinal 5-HT3 receptors (5-HT3Rs) originating from superficial dorsal horn NK1-expressing neurons and that relays through the parabrachial nucleus and the rostroventral medial medulla to act on deep dorsal horn neurons is known be important in maintaining these pain-like states. To determine if spinal rapamycin-sensitive pathways are activated by a descending serotonergic drive, we investigated the effects of spinally administered rapamycin on responses of deep dorsal horn neurons that had been pre-treated with the selective 5-HT3R antagonist ondansetron. We also investigated the effects of spinally administered cell cycle inhibitor (CCI)-779 (a rapamycin ester analogue) on deep dorsal horn neurons from rats with carrageenan-induced inflammation of the hind paw. Unlike some other models of persistent pain, this model does not involve an altered 5-HT3R-mediated descending serotonergic drive. We found that the inhibitory effects of rapamycin were significantly reduced for neuronal responses to mechanical and thermal stimuli when the spinal cord was pre-treated with ondansetron. Furthermore, CCI-779 was found to be ineffective in attenuating spinal neuronal responses to peripheral stimuli in carrageenan-treated rats. Therefore, we conclude that 5-HT3R-mediated descending facilitation is one requirement for activation of rapamycin-sensitive pathways that contribute to persistent pain-like states. PMID:20709148

    Full Text Available Methods: 21 patients (17 men, 4 women; mean age 66.1 years, range 29-90 years with 15 true aneurysms, and 6 type B-dissections were treated by implantation of a TalentTM Endoluminal Stentgraft System from February 2000 to July 2003. In 3 cases it was necessary to overstent the left subclavian artery, in 1 case to overstent the left common carotid. Results: 2 patients (9.5% died during the first 30 days (1 myocardial infarction, 1 pneumonia. Two patients (9.5% suffered from cerebral ischemia and needed revascularisation. No paraplegia, no stroke occurred. One endoleak required additional stenting. No patient needed conversion. Follow-up, average 25.4 months (range 0-39, was 100% complete. During this another two patients died of myocardial infarction i.e. 9.5% (the above mentioned endoleak, but no late migration were detected in the remaining patients. In all cases the graft lumen stayed patent. Conclusions: Treatment of descending thoracic aortic aneurysm with an endovascular approach has acceptable mortality and morbidity-rates even in high risk patients. Procedural overstenting of the subclavian artery requires subclavian revascularisation in a minority of cases.

    Now special interest in the scientific world acquiring the researches on influence of radiation and estimation of the remote consequences of an irradiation on a genome of the man with the help of modern molecular-genetic methods. The decision of this problem has connected with reception and preservation of a hereditary material at cohorts who were exposed to an irradiation. Such cohort are the workers of the first atomic enterprise in Russia. In period of starting of this enterprise the workers were exposed by a chronic irradiation and combined radiation (Pu-239) in more then permissible doses. Now average age of these workers exceed 65 years. With the purpose of study of genetic consequences of an irradiation in Branch N 1 the Biophysics Institute Russian Federation (Ozyorsk, Chelyabinsk region) DNA Bank is creating. The methodological and methodical bases of its creation are developed. The creation of DNA Bank will enable widely to use the saved genetic material in the newest techniques for the analysis mini - and microsatellite DNA, structural genes (genes of a reparation and stress-response genes), both in somatic (parents), and in germinal cells of the individuals (descendants). The selection of families for DNA study is rather wide - one of the parents is irradiated or both parents have exposed to radiation. DNA, received from sputum and blood serum of the workers with incorporation Pu (the group of risk) will allow to investigate a role of some genes (K-ras, p16, p53) in development of tumor process.

    More than 400 nuclear explosion tests were conducted at the Semipalatinsk Nuclear Test Site (SNTS) and significant radioactive substances were released. The long-term consequences of the activities at the SNTS and the appearance of any hereditary effects remain insufficiently studied about 25 years after the test site was closed. The population living in villages near the SNTS are considered to have been heavily exposed to external and internal radiation. This study aims to perform an assessment and comprehensive cytogenetic analysis of the inhabitants living near the SNTS, and their first-(F1) and second-(F2) generation children. Residents of the East Kazakhstan region living in the area covered by the former SNTS were included in the study. To evaluate the hereditary effects of nuclear testing, comprehensive chromosome analyses were performed in lymphocytes using conventional Giemsa and fluorescent in situ hybridization methods in 115 F1 and F2 descendants in the villages of Dolon and Sarzhal, which were heavily contaminated. The parents of the subjects had permanently lived in the villages. A higher number of stable-type chromosome aberrations such as translocations was found in these residents than in 80 residents of the control area, Kokpecty, which indicates the possibility that radiation had biological effects on the exposed subjects.

    Introduction  We describe a two-port laparoscopic technique to create a colostomy in the descending colon with separated stomas for newborns with anorectal malformations. Material and Methods  Six patients with an anorectal malformation underwent this procedure in the early-neonatal period. The surgical technique was performed with two ports, which allows for an accurate inspection of the abdominal contents. The first loop of the sigmoid colon is grasped through the first port and exteriorized while the attachments to the left retroperitoneum and direction of the loop are checked with the scope introduced in the second port. The division of the colon is performed extracorporally, the colon irrigated of meconium, and the distal colon moved to the second port incision. Both stomas are then fixed to the abdominal wall. Results  The time of the procedure ranged from 50 to 90 minutes. A Mullerian duplication was noted in one case. Oral intake was started during the first 12 to 24 hours. No complications were seen during or after the procedure. Conclusions  This technique allows for the precise localization of the colostomy with direct visualization, provides for the inspection of the internal genitalia, eliminates the incision between the two stomas and its complications, allows for painless stoma bag changes immediately after surgery, avoids twisting of the colostomy, and permits a cosmetically pleasing incision at the colostomy closure.

    Percutaneous transluminal coronary angioplasty (PTCA) was successfully performed in 20 patients with 1-vessel left anterior descending (LAD) coronary artery disease. Exercise capacity in terms of peak workload, heart rate and systolic blood pressure all increased significantly 1 week after PTCA. All patients had some decrease in stenosis size and gradient. All patients except 1 had an improvement in functional class. Eight of 12 patients with abnormal exercise electrocardiograms before PTCA had normal electrocardiograms after the procedure. Exercise thallium-201 (TI-201) myocardial perfusion images obtained in all 20 patients before and 1 week after PTCA were analyzed using a new computer method designed to quantitate regional myocardial TI-201 distribution, redistribution and clearance rate. Significant improvement in TI-201 activity was present in the anterior and septal segments of the left ventricle 1 week after PTCA. This increase in TI-201 uptake was associated with a significant reduction in the amount of TI-201 redistribution between initial and delayed postexercise images in the same regions. TI-201 clearance rate in the segments supplied by the dilated vessel also improved significantly. Abnormal TI-201 lung uptake was seen in 17 patients before and in 4 patients after PTCA. Exercise ejection fraction response and septal wall motion also improved after PTCA of the LAD stenosis in all 17 patients who had exercise radionuclide ventriculography

    Objective. To evaluate the mid-term feasibility, efficacy, and durability of descending thoracic aortic aneurysm (DTAA) exclusion using the EndoFit device (LeMaitre Vascular). Methods. Twenty-three (23) men (mean age 66 years) with a DTAA were admitted to our department for endovascular repair (21 were ASA III+ and 2 refused open repair) from January 2003 to July 2005. Results. Complete aneurysm exclusion was feasible in all subjects (100% technical success). The median follow-up was 18 months (range 8-40 months). A single stent-graft was used in 6 cases. The deployment of a second stent-graft was required in the remaining 17 patients. All endografts were attached proximally, beyond the left subclavian artery, leaving the aortic arch branches intact. No procedure-related deaths have occurred. A distal type I endoleak was detected in 2 cases on the 1 month follow-up CT scan, and was repaired with reintervention and deployment of an extension graft. A nonfatal acute myocardial infarction occurred in 1 patient in the sixth postoperative month. Graft migration, graft infection, paraplegia, cerebral or distal embolization, renal impairment or any other major complications were not observed. Conclusion. The treatment of DTAAs using the EndoFit stent-graft is technically feasible. Mid-term results in this series are promising

    Descending fiber projections to the lizard spinal cord were studied using anterograde axonal degeneration. Following hemisection of the cord at the first spinal segment, degeneration was found in the white and gray matter as far down as the 31st (caudal) segment. Degenerating fibers in the white matter were confined to the ipsilateral side and were found in the medial longitudinal fasiculus and the outer half ot the lateral and ventral funiculi. Degeneration was more intense in the dorsolateral and ventromedial funiculi than in the ventrolateral funiculus. In the gray matter, REXED's criteria were applied to Nissl-stained material to delimit boundaries of ten laminae. Degeneration of suprospinal axons was most intense in the medial part of VII, dorsal and ventral commissures to ramify contralaterally in the medial part of VII, in VII, and in medial IX. No degeneration was present in the lateral part of the spinal gray on the contralateral side. In Golgi-stained material, dendrites of lateral IX cells were seen to extend into lamina VII, the dorsolateral part of VII, and the lateral funiculus. Thus, fibers of the ventromedial supraspinal pathway may make axodendritic contact with motoneurons of lateral IX as well as medial IX, ipsilaterally. In addition, there is a possibility of a crossed connection to contralateral motoneurons.

    In this study, the biomechanical characteristic of a newly developed adjustable hemipelvic prosthesis under dynamic loading conditions was investigated using explicit finite element method. Both intact and reconstructed pelvis models, including pelvis, femur and soft tissues, were established referring to human anatomic data using a solid geometry of a human pelvic bone. Hip contact forces during ascending stairs and descending stairs were imposed on pelvic models. Results showed that maximum von Mises stresses in reconstructed pelvis were 421.85 MPa for prostheses and 109.12 MPa for cortical bone, which were still within a low and elastic range below the yielding strength of Ti-6Al-4V and cortical bone, respectively. Besides, no significant difference of load transferring paths along pelvic rings was observed between the reconstructed pelvis and natural pelvis models. And good agreement was found between the overall distribution of maximum principal stresses in trabecular bones of reconstructed pelvis and natural pelvis, while at limited stances, principal stresses in trabecular bone of reconstructed pelvis were slightly lower than natural pelvis. The results indicated that the load transferring function of pelvis could be restored by this adjustable hemipelvic prosthesis. Moreover, the prosthesis was predicted to have a reliable short- and long-term performance. However, due to the occurrence of slightly lower principal stresses at a few stances, a porous structure applied on the interface between the prosthesis and bone would be studied in future work to obtain better long-term stability. © IMechE 2016.

    Coronal rain clumps and prominence knots are dense condensations with chromospheric to transition region temperatures that fall down in the much hotter corona. Their typical speeds are in the range 30–150 km s{sup −1} and of the order of 10–30 km s{sup −1}, respectively, i.e., they are considerably smaller than free-fall velocities. These cold blobs contain a mixture of ionized and neutral material that must be dynamically coupled in order to fall together, as observed. We investigate this coupling by means of hydrodynamic simulations in which the coupling arises from the friction between ions and neutrals. The numerical simulations presented here are an extension of those of Oliver et al. to the partially ionized case. We find that, although the relative drift speed between the two species is smaller than 1 m s{sup −1} at the blob center, it is sufficient to produce the forces required to strongly couple charged particles and neutrals. The ionization degree has no discernible effect on the main results of our previous work for a fully ionized plasma: the condensation has an initial acceleration phase followed by a period with roughly constant velocity, and, in addition, the maximum descending speed is clearly correlated with the ratio of initial blob to environment density.

    When a sphere descends at constant speed in a salt-stratified water, a thin and high-speed jet is often generated above the sphere. The phenomenon has first been observed by shadowgraph and then has been investigated numerically. In this study, a systematic measurement by particle image velocimetry (PIV) has been performed for a wide range of Froude number Fr and Reynolds number Re , to actually observe the numerically simulated velocity distributions and confirm the accuracy of the numerical simulations for a very high Schmidt (Prandtl) number of Sc =(Pr =) 700 . The results show that the radius of the jet is proportional to both Fr 1 / 2 and Re - 1 / 2 , meaning that it is proportional to √{ Fr / Re } (when F < 1). The boundary layer on the sphere surface has a thickness comparable to the jet radius, and it is also proportional to √{ Fr / Re }. These results are in agreement with the recent numerical simulations and a simple dimensional analysis. Typical diverging internal-wave patterns, whose vertical wavelength has been predicted to be proportional to Fr , could also be observed.

    The transatlantic slave trade was the largest forced migration in world history. However, the origins of the enslaved Africans and their admixture dynamics remain unclear. To investigate the demographic history of African-descendant Marron populations, we generated genome-wide data (4.3 million markers) from 107 individuals from three African-descendant populations in South America, as well as 124 individuals from six west African populations. Throughout the Americas, thousands of enslaved Africans managed to escape captivity and establish lasting communities, such as the Noir Marron. We find that this population has the highest proportion of African ancestry (∼98%) of any African-descendant population analyzed to date, presumably because of centuries of genetic isolation. By contrast, African-descendant populations in Brazil and Colombia harbor substantially more European and Native American ancestry as a result of their complex admixture histories. Using ancestry tract-length analysis, we detect different dates for the European admixture events in the African-Colombian (1749 CE; confidence interval [CI]: 1737-1764) and African-Brazilian (1796 CE; CI: 1789-1804) populations in our dataset, consistent with the historically attested earlier influx of Africans into Colombia. Furthermore, we find evidence for sex-specific admixture patterns, resulting from predominantly European paternal gene flow. Finally, we detect strong genetic links between the African-descendant populations and specific source populations in Africa on the basis of haplotype sharing patterns. Although the Noir Marron and African-Colombians show stronger affinities with African populations from the Bight of Benin and the Gold Coast, the African-Brazilian population from Rio de Janeiro has greater genetic affinity with Bantu-speaking populations from the Bight of Biafra and west central Africa.

    We extended a region-based mathematical model of the renal medulla of the rat kidney, previously developed by us, to represent new anatomic findings on the vascular architecture in the rat inner medulla (IM). In the outer medulla (OM), tubules and vessels are organized around tightly packed vascular bundles; in the IM, the organization is centered around collecting duct clusters. In particular, the model represents the separation of descending vasa recta from the descending limbs of loops of Henle, and the model represents a papillary segment of the descending thin limb that is water impermeable and highly urea permeable. Model results suggest that, despite the compartmentalization of IM blood flow, IM interstitial fluid composition is substantially more homogeneous compared with OM. We used the model to study medullary blood flow in antidiuresis and the effects of vascular countercurrent exchange. We also hypothesize that the terminal aquaporin-1 null segment of the long descending thin limbs may express a urea-Na+ or urea-Cl− cotransporter. As urea diffuses from the urea-rich papillary interstitium into the descending thin limb luminal fluid, NaCl is secreted via the cotransporter against its concentration gradient. That NaCl is then reabsorbed near the loop bend, raising the interstitial fluid osmolality and promoting water reabsorption from the IM collecting ducts. Indeed, the model predicts that the presence of the urea-Na+ or urea- Cl− cotransporter facilitates the cycling of NaCl within the IM and yields a loop-bend fluid composition consistent with experimental data.

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

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

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

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

    Objective: To assess the relationship between left anterior descending (LAD) coronary artery myocardial bridging detected by 64-slice computed tomography (CT) and clinical findings. Methods: 221 consecutive patients were examined with coronary 64-slice CT angiography. 21 patients with coronary stenosis >50% were excluded. The length, depth, and luminal narrowing of LAD myocardial bridges during systole and diastole were measured. CT findings were compared with the treadmill ECG-stress test, and clinical symptoms. Results: Myocardial bridges of the LAD were found in 23% of patients (51/221) (length, 14.9 ± 6.5 mm; depth, 2.6 ± 1.6 mm). A significant difference was noted between the LAD luminal diameter before the intramyocardial course and intramyocardially, for both diastole and systole (p 50% was found in 3/25 (8%). 30/51 (59%) of bridges were 'deep' (>2 mm myocardial depth), 21/51 (41%) were 'superficial'. The prevalence of a positive ECG-stress tests for the anterior myocardial region was significantly higher in patients with LAD myocardial bridges (34/50; 68%) compared to those without (28/144; 19.4%) (p < 0.001). There was no difference between 'superficial' and 'deep' LAD myocardial bridges in regard to a positive treadmill ECG-stress test. Typical angina was rare with 6%. Conclusion: LAD myocardial bridges are common findings and can possibly explain a positive exercise ECG-stress test for anterior myocardial ischemia. Intramyocardial LAD segments show mild-to-moderate luminal narrowing at rest, which is higher during end-systolic phase.

  1. Allelic lineages of the ficolin genes (FCNs are passed from ancestral to descendant primates.

    Directory of Open Access Journals (Sweden)

    Tina Hummelshøj

    Full Text Available The ficolins recognize carbohydrates and acetylated compounds on microorganisms and dying host cells and are able to activate the lectin pathway of the complement system. In humans, three ficolin genes have been identified: FCN1, FCN2 and FCN3, which encode ficolin-1, ficolin-2 and ficolin-3, respectively. Rodents have only two ficolins designated ficolin-A and ficolin-B that are closely related to human ficolin-1, while the rodent FCN3 orthologue is a pseudogene. Ficolin-2 and ficolin-3 have so far only been observed in humans. Thus, we performed a systematic investigation of the FCN genes in non-human primates. The exons and intron-exon boundaries of the FCN1-3 genes were sequenced in the following primate species: chimpanzee, gorilla, orangutan, rhesus macaque, cynomolgus macaque, baboon and common marmoset. We found that the exon organisation of the FCN genes was very similar between all the non-human primates and the human FCN genes. Several variations in the FCN genes were found in more than one primate specie suggesting that they were carried from one species to another including humans. The amino acid diversity of the ficolins among human and non-human primate species was estimated by calculating the Shannon entropy revealing that all three proteins are generally highly conserved. Ficolin-1 and ficolin-2 showed the highest diversity, whereas ficolin-3 was more conserved. Ficolin-2 and ficolin-3 were present in non-human primate sera with the same characteristic oligomeric structures as seen in human serum. Taken together all the FCN genes show the same characteristics in lower and higher primates. The existence of trans-species polymorphisms suggests that different FCN allelic lineages may be passed from ancestral to descendant species.

  2. Descending projections of the hamster intergeniculate leaflet: relationship to the sleep/arousal and visuomotor systems

    The intergeniculate leaflet (IGL), homolog of the primate pregeniculate nucleus, modulates circadian rhythms. However, its extensive anatomical connections suggest that it may regulate other systems, particularly those for visuomotor function and sleep/arousal. Here, descending IGL-efferent pathways are identified with the anterograde tracer, Phaseolus vulgaris leucoagglutinin, with projections to over 50 brain stem nuclei. Projections of the ventral lateral geniculate are similar, but more limited. Many of the nuclei with IGL afferents contribute to circuitry governing visuomotor function. These include the oculomotor, trochlear, anterior pretectal, Edinger-Westphal, and the terminal nuclei; all layers of the superior colliculus, interstitial nucleus of the medial longitudinal fasciculus, supraoculomotor periaqueductal gray, nucleus of the optic tract, the inferior olive, and raphe interpositus. Other target nuclei are known to be involved in the regulation of sleep, including the lateral dorsal and pedunculopontine tegmentum. The dorsal raphe also receives projections from the IGL and may contribute to both sleep/arousal and visuomotor function. However, the locus coeruleus and medial vestibular nucleus, which contribute to sleep and eye movement regulation and which send projections to the IGL, do not receive reciprocal projections from it. The potential involvement of the IGL with the sleep/arousal system is further buttressed by existing evidence showing IGL-efferent projections to the ventrolateral preoptic area, dorsomedial, and medial tuberal hypothalamus. In addition, the great majority of all regions receiving IGL projections also receive input from the orexin/hypocretin system, suggesting that this system contributes not only to the regulation of sleep, but to eye movement control as well.

    The aim of this study was to assess clinical and contemporary costs associated with elective endovascular repair of intact descending thoracic aortic aneurysms (DTAA) into the mid-term follow-up. A retrospective review of a prospectively maintained clinical database including 29 consecutive patients from July 2005 to December 2009 treated with elective endovascular repair (TEVAR) or TEVAR and surgical infrarenal repair (hybrid) of intact DTAA was performed. Mean age was 74.5 years old (±7.1). Primary clinical endpoints include mortality and major morbidity. Additionally a comprehensive economic appraisal of individual in-hospital and follow-up costs was executed. Economic endpoints include in-hospital and follow-up costs and patient discharge status. Elective endovascular and open repairs' clinical and economical outcomes in contemporary literature were assessed for comparison according to PRISMA standards. Immediate mortality was 6.9% (1/24 TEVAR and 1/5 hybrid). Three respiratory complications were recorded (11%; 2 TEVAR, 1 hybrid). Renal and cardiac complication rates were 7.4% (1 TEVAR, 1 hybrid) and 3.7% (1 TEVAR) respectively. Routine discharge home was achieved for 85% of patients (95.7% TEVAR, 25% hybrid). Three endoleaks were treated throughout the follow-up (2 TEVAR, 1 hybrid; mean 30.4 mo, ±19.9) rendering an 11% (3/27) reintervention rate. Average immediate cost was €21,976.87 for elective endovascular repair and €33,783.21 for elective endovascular hybrid repair. Additional reintervention and routine follow-up costs augmented immediate costs by 12.4%. This study supports satisfying immediate clinical outcomes for TEVAR and TEVAR+surgical infrarenal procedures. Although limited by a small population size and difficulties in economic comparisons, this study presents the real world social and economic cost scenario for both elective TEVAR and TEVAR hybrid treatment of DTAA of both the in-hospital and at mid term follow-up periods.

  4. Descendants of Hardship: Prevalence, Drivers and Scarring Effects of Social Exclusion in Childhood

    Full Text Available The social exclusion of children is problematic for two reasons. Young people typically inherit their marginal position from their family, and therefore cannot be held responsible for their hardship themselves; and social exclusion in childhood may affect their wellbeing and subsequent development, possibly leading to a “scarring effect” in later life. In this contribution we develop an instrument for measuring social exclusion among children. Social exclusion is regarded as a theoretical construct with four sub-dimensions: material deprivation, limited social participation, inadequate access to social rights, and a lack of normative integration. First we analyse data from a survey of 2,200 Dutch children, which contains a large set of social exclusion items. We applied nonlinear principal components analysis in order to construct a multidimensional scale. Measured in this way, the prevalence of social exclusion among children is 4.5%. Boys and children living in large families are more likely to experience social exclusion than girls and children with few siblings. The parental level of education and dependency on social security benefits are also important driving factors of childhood social exclusion. Subsequently we investigate the scarring effect. Longitudinal administrative income and household data covering 25 years were combined with a new survey of just under 1,000 Dutch adults, a third of whom were poor as a child. The survey assessed their past and current degree of social exclusion, and their health and psychosocial development, educational career, past family circumstances, etc. In an absolute sense scarring turns out to have been limited during this period: a very large majority of those who were poor or excluded as a child are above the threshold values in adult life. However, the “descendants of hardship” are still more likely to be socially excluded as adults than people who grew up in more favourable conditions. A

    Thoracic endovascular aortic repair has a lower perceived risk than open surgical repair and has become an increasingly popular alternative. Whether general consensus exists regarding candidacy for either operation among open and endovascular specialists is unknown. A retrospective review of isolated descending thoracic aortic aneurysm at our institution between January 2005 and October 2015 was performed, excluding trauma and dissection. Two cardiac surgeons, 2 cardiovascular surgeons, 1 vascular surgeon, and 1 interventional radiologist gave their preference for open vs endovascular repair. Interobserver agreement was assessed with the kappa coefficient. k-means clustering agnostically grouped various patterns of agreement. The mean rating was predicted using least absolute shrinkage and selection operator regression. Negative binomial regression predicted the discrepancy between our panel of raters and the historical operation. Generalized estimating equation modeling was then used to evaluate the association between the extent of discrepancy and the adverse perioperative outcome. There were 77 patients with preoperative imaging studies. Pairwise interobserver agreement was only fair (median weighted kappa 0.270 [interquartile range 0.211-0.404]). Increasing age and proximal neck length predicted an increasing preference for thoracic endovascular aortic repair in our panel; larger proximal neck diameter predicted a general preference for open surgical repair. Increasing proximal neck diameter predicted a larger discrepancy between our panel and the historical operation. Greater discrepancy was associated with adverse outcome. Substantial disagreement existed among our panel, and an exploratory analysis of the effect of increasing discrepancy demonstrated an association with adverse perioperative outcome. An investigation of the effect of a thoracic aortic team with open and endovascular specialists is warranted. Copyright © 2017 Elsevier Inc. All rights

    Full Text Available BACKGROUND: Descending kerbs during locomotion involves the regulation of appropriate foot placement before the kerb-edge and foot clearance over it. It also involves the modulation of gait output to ensure the body-mass is safely and smoothly lowered to the new level. Previous research has shown that vision is used in such adaptive gait tasks for feedforward planning, with vision from the lower visual field (lvf used for online updating. The present study determined when lvf information is used to control/update locomotion when stepping from a kerb. METHODOLOGY/PRINCIPAL FINDINGS: 12 young adults stepped down a kerb during ongoing gait. Force sensitive resistors (attached to participants' feet interfaced with an high-speed PDLC 'smart glass' sheet, allowed the lvf to be unpredictably occluded at either heel-contact of the penultimate or final step before the kerb-edge up to contact with the lower level. Analysis focussed on determining changes in foot placement distance before the kerb-edge, clearance over it, and in kinematic measures of the step down. Lvf occlusion from the instant of final step contact had no significant effect on any dependant variable (p>0.09. Occlusion of the lvf from the instant of penultimate step contact had a significant effect on foot clearance and on several kinematic measures, with findings consistent with participants becoming uncertain regarding relative horizontal location of the kerb-edge. CONCLUSION/SIGNIFICANCE: These findings suggest concurrent feedback of the lower limb, kerb-edge, and/or floor area immediately in front/below the kerb is not used when stepping from a kerb during ongoing gait. Instead heel-clearance and pre-landing-kinematic parameters are determined/planned using lvf information acquired in the penultimate step during the approach to the kerb-edge, with information related to foot placement before the kerb-edge being the most salient.

    Full Text Available Abstrak OSPF (Open Shortest Path First dan EIGRP (Enhanced Interior Gateway Routing Protocol adalah dua routing protokol yang banyak digunakan dalam jaringan komputer. Perbedaan karakteristik antar routing protokol menimbulkan masalah dalam pengiriman paket data. Teknik redistribution adalah solusi untuk melakukan komunikasi antar routing protokol. Dengan menggunakan software Cisco Packet Tracer 5.3 pada penelitian ini dibuat simulasi OSPF dan EIGRP yang dihubungkan oleh teknik redistribution, kemudian dibandingkan kualitasnya dengan single routing protokol EIGRP dan OSPF. Parameter pengujian dalam penelitian ini adalah nilai time delay dan trace route. Nilai trace route berdasarkan perhitungan langsung cost dan metric dibandingkan dengan hasil simulasi. Hasilnya dapat dilakukan proses redistribution OSPF dan EIGRP. Nilai delay redistribution lebih baik 1% dibanding OSPF dan 2-3% di bawah EIGRP tergantung kepadatan traffic. Dalam perhitungan trace route redistribution dilakukan 2 perhitungan, yaitu cost untuk area OSPF dan metric pada area EIGRP. Pengambilan jalur utama dan alternatif pengiriman paket berdasarkan nilai cost dan metric yang terkecil, hal ini terbukti berdasarkan perhitungan dan simulasi.

    Full Text Available Le Silence de la mer, écrit en 1941 et publié en 1942, est un livre culte qui a consacré son auteur Vercors – de son vrai nom Jean Bruller - comme un des écrivains de la Résistance. A la Libération, ce premier volume de la maison d’édition clandestine les Editions de Minuit, a été immédiatement réimprimé, puis suivi d’une adaptation théâtrale en 1949 dans une mise en scène de Jean Mercure, et du film très fidèle de Jean-Pierre Melville. Si on ne l’a pas lu, on en connaît du moins l’histoire, celle d’un officier allemand Werner von Ebrennac qu’un oncle et sa nièce sont obligés d’accueillir dans leur maison. Chaque soir, cet homme cultivé comble le silence, forme de résistance de ses hôtes, par ses monologues illusoires exprimant son espoir d’union entre l’Allemagne et la France. Quand il apprend finalement les véritables intentions de son pays, il se résigne, ce que le narrateur réprouve hautement, s’engage pour le front de l’est et quitte à jamais la nièce, symbole dans son esprit de cette France digne qu’il admire et aime tant.Ce livre incontournable, posé librement aujourd’hui sur les étagères des bibliothèques publiques et privées, a été largement commenté. Nous nous risquons néanmoins à proposer une nouvelle entrée : dans ce bref essai, nous nous permettrons de pénétrer dans ce récit par le biais de la bibliothèque qui trône majestueusement dans la salle de l’oncle et de sa nièce et nous essaierons de montrer que cet espace symbolique offre une circulation riche d’interprétations nombreuses de l’imaginaire du texte au réel le plus immédiat.

    2013-02-01

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

Adapun keluhan yang dialami ini seperti bunyi mendengung, mendesis, menderu, atau berbagai variasi bunyi yang lain. Tinitus bukanlah penyakit atau sindroma, tapi hanya merupakan gejala yang mungkin berasal dari satu atau sejumlah kelainan. Sebetulnya suara yang terdengar oleh telinga tersebut belum tentu bersifat kelainan atau patologis. Jika orang sehat yang terbukti telinganya normal, berada dalam ruang kedap (anehoic chamber, maka ia akan dapat mendengar berbagai macam suara yang berasal dari berbagai organ tubuhnya sendiri yang memang bekerja setiap saat, contohnya: pernapasan, kontraksi jantung, dan aliran darah. Kenyataannya, dalam kehidupan sehari-hari, suasana yang memungkinkan suara fisiologis atau normal tersebut terdengar oleh seseorang sangat jarang tercipta dan bahkan dalam kamar yang sunyi di malam hari sekalipun. Hal ini dikarenakan, bunyi masking dari lingkungan dengan berintensitas bunyi sekitar 25 – 30 dB. Tinitus baru menjadi gejala jika suara organ tubuh intensitasnya melebihi bunyi masking lingkungan tadi. Tinitus kerap diderita terutama orang pada kelompok usia pertengahan dan usia tua. Menurut data statistic dari pusat kesehatan di Amerika, sekitar 32% orang dewasa pernah mengalami tinitus pada suatu saat tertentu dalam hidupnya, dan 6 % nya sangat menganggu dan cukup sulit disembuhkan. Di Inggris, 17% populasi juga memiliki masalah tinitus. Sayangnya di Indonesia belum ada data statistic yang memadai, namun berdasarkan pengalaman empiris, penderita tinitus cukup banyak dan sering ditemui di tempat praktek, klinik, maupun rumah sakit. Meski tinitus bukanlah keadaan yang membahayakan, munculnya gejala ini pada hampir kebanyakan orang sangat mengganggu dan sering mempengaruhi kualitas hidup dan pekerjaannya.

    During descending on a slope, the speed of Electric Powered Wheelchair (EPW) tends to changed rapidly. Normally, most EPW is provided with mechanical braking system which transfers human pulling force of the lever creating friction at the tire. However, the task is difficult for the users are elderly or paralyses. However, even for normal user with good strength, in fear condition they tend to give sudden braking which leads to tire locking up and skidding, eventually EPW unstable. These problems will cause accident and injuries to the users if speed does not properly control. In this paper, the automated braking torque control method was proposed in EPW as alternative to solve this problem and increase the mobility and stability especially during descending on slope in other to help the user of the EPW as their daily transportation. In this research, Proportional-Integral-Derivative and Sliding Mode Control controller are compared to determine the best response for torque braking control. The rapid change of speed can be controlled by the braking torque using proposed controllers based on the desired constant speed set by the control designer. Moreover, the sudden braking that caused tire to lock up and skid can be avoided. Furthermore, result from SMC shows this controller have good time respond to maintain the speed based on desired value when descending at slope condition by controlling the braking torque compared to the PID controller.

    Background Haitian migrants played an important role shaping Cuban culture and traditional ethnobotanical knowledge. An ethnobotanical investigation was conducted to collect information on medicinal plant use by Haitian immigrants and their descendants in the Province of Camagüey, Cuba. Methods Information was obtained from semi-structured interviews with Haitian immigrants and their descendants, direct observations, and by reviewing reports of traditional Haitian medicine in the literature. Results Informants reported using 123 plant species belonging to 112 genera in 63 families. Haitian immigrants and their descendants mainly decoct or infuse aerial parts and ingest them, but medicinal baths are also relevant. Some 22 herbal mixtures are reported, including formulas for a preparation obtained using the fruit of Crescentia cujete. Cultural aspects related to traditional plant posology are addressed, as well as changes and adaptation of Haitian medicinal knowledge with emigration and integration over time. Conclusion The rapid disappearance of Haitian migrants' traditional culture due to integration and urbanization suggests that unrecorded ethnomedicinal information may be lost forever. Given this, as well as the poor availability of ethnobotanical data relating to traditional Haitian medicine, there is an urgent need to record this knowledge. PMID:19450279

    1992-01-01

    To assess the physiologic significance of well-developed collaterals, 34 patients, with isolated left anterior descending artery disease (LAD) and without overt prior myocardial infarction, underwent cardiac catheterization and exercise thallium-201 emission computed tomography. The patients were divided into 3 groups: 11 patients with 90% stenosis of the proximal LAD and without collaterals (group 1), 11 with 99% stenosis of the proximal LAD, and without collaterals (group 2) and 12 with a total occlusion of the proximal LAD which was completely filled by well-developed collaterals (group 3). On left ventriculography, shortening fractions of the anterior wall were significantly reduced in group 2 as compared to groups 1 and 3 (group 1 vs group 2: p<0.01, group 2 vs group 3: p<0.05), which reflected the lower ejection fraction of group 2 (p<0.01 and p<0.05, respectively). The perfusion defects of the anterior wall on both the initial and the delayed images were severer in groups 2 and 3 than in group 1 (group 1 vs group 2 and group 1 vs group 3 on the initial image: p<0.01, for both, group 1 vs group 2 and group 1 vs group 3 on the delayed image: p<0.05, for both). However, recovery of the perfusion defects from the initial image to the delayed image was better in group 3 than in groups 1 and 2 (group 1 vs group 2 and group 1 vs group 3: p<0.05, for both). Therefore, coronary blood flow through well-developed collaterals was considered to be comparable to the flow through a diseased vessel with 90% stenosis at rest. During maximal exercise, blood flow through well-developed collaterals was considered to be comparable to the flow through a diseased vessel with 99% stenosis, although the blood flow through well-developed collaterals was considered to be better than that through 99% stenosis during the recovery period. These findings suggest that patients with well-developed collaterals must be treated like those with severe stenosis. (author)

    Full Text Available Background: Complete obstruction of the abdominal aorta at the renal artery level is a difficult surgical problem. Aortic clamping and declamping can lead to profound haemodynamic changes, myocardial infarction, ventricular failure or even death may result. These complications are important challenges in anesthetic management of these patients. Methods :0 Between August, 2010 and April, 2012, descending thoracic aorta to femoral artery bypass grafting was used to revascularize lower limbs in 11 patients in our institute. The anesthetic management of these patients is described here. Epidural catheter placement was done in T 5-6 or T 6-7 space for post operative pain relief. Induction was done by, Inj. Glycopyrolate 0.2 mg, Inj. Fentanyl 5 μg/kg., Inj. Pentothal sodium 5 mg/kg, Inj. Rocuronium 0.9 mg/kg, IPPV done. Left sided double lumen tube was inserted, Maintenance of Anesthesia was done by O 2 + N 2 O (30:70. Increments of Vecuronium and Fentanyl were given Monitoring of Heart rate, arterial pressure, central venous pressure were continuously displayed. The available pharmacological agents were used when there is deviation of more than 15% from base line. Results: In our study, inspite of measures taken to control rise in blood pressure during aortic cross clamping, a rise of 90 mm of Hg in one patient and 60-80 mm of Hg in four patients was observed, which was managed by sodium nitropruside infusion. At the end of surgery seven patients were extubated on the operation table. In remaining four patients DLT was replaced by single lumen endotracheal tube and were shifted to ICU on IPPV. They weaned off gradually in 3-5 hours. In our series blood loss was 400 ml to 1000 ml. There was no mortality in the first 24 hours. Postoperative bleeding was reported in one case which was re-explored and stood well. Conclusion: The anesthetic technique during aortic surgery is directed at minimizing the hemodynamic effects of cross clamping in order to

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

    Full Text Available Annie Ernaux, considérée comme l’une des femmes écrivaines les plus célèbres du XXIe siècle, a exprimé l’angoisse commune de son âge et de son passé en rédigeant Les Années. Elle n’avait pas non seulement le but de décrire sa vie, mais aussi d’esquisser l’histoire de la société française à laquelle elle appartient. Lorsqu’elle est venue au monde en 1940, le monde était au seuil de la Seconde Guerre mondiale. Etant élevée dans cette atmosphère chaotique, elle a appris beaucoup de choses de sa société, de sa famille et de son environnement. Annie Ernaux a découvert le monde comme une jeune fille, une mère, une épouse et une grand-mère. Ses expériences sociales et familiales l’ont beaucoup mûrie et elle a commencé à rédiger ses pensées. Ses souvenirs ont fait partie de ses écritures autobiographiques. Dans Les Années, Annie Ernaux a profité de toutes ses expériences personnelles et sociales avec de différents moyens. Elle a essayé d’établir des liens entre l’histoire de sa vie et celle de la société. Elle a accordé une importance à la vie sociale plutôt que sa propre vie dans Les Années. Elle y a développé des propres techniques d’écriture en se servant des photos familiales et personnelles, d’un film, d’une vidéo, des marques de publicité, des chansons, d’un tableau, des notes de journal ainsi que des événements sociologiques et historiques. Elle a ainsi créé une nouvelle forme d’autobiographie : autobiographie impersonnelle.

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

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

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

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

    Full Text Available CORELATION BETWEEN ISLAM AND ECONOMY. This paper aims to identifies about the correlation between economic and Islam. Islam is the perfect religion that governs all things in life, including the economy. This is evident with the concept of  well-being which is described in the al-Quran and Sunnah. Basically the goal of every human life is to prosper, although humans make sense of  well- being with a different perspective. Most understand economics assume that welfare is the welfare of  earthly material. But to make sense of well-being with the term al-Falah, is meaning holistic wellbeing and balance between material and spiritual dimensions. al-Quran and Sunnah have taught that the human being will be achieved if  living in balance between material and spiritual. This is because human life does not just stop in the life of this world, but there is still a second life that will be faced by humanity in the hereafter, and well-being will be achieved with the truth is that people can balance the needs of the world and the hereafter, and that is what is taught in Islamic economics. Keywords: Islam, Economy, Prosperity. Tulisan ini bertujuan untuk menjelasakn tentang korelasi antara ekonomi  dan  Islam.  Islam  adalah  agama  yang  sempurna  yang mengatur segala hal dalam kehidupan ini, termasuk juga ekonomi. Hal ini terbukti dengan konsep kesejahteraan yang dipaparkan dalam al-Quran dan Sunnah. Pada dasarnya tujuan hidup setiap manusia adalah untuk mencapai kesejahteraan, meskipun manusia memaknai kesejahteraan dengan perspektif  yang berbeda-beda. Sebagian besar paham ekonomi menganggap bahwa kesejahteraan adalah kesejahteraan material duniawi. Namun Islam memaknai kesejahteraan dengan istilah  Falah  yang  berarti  kesejahteraan  holistik  dan  seimbang antara dimensi material dan spiritual. Al-Quran dan Sunnah telah mengajarkan bahwa kesejahteraan akan tercapai jika manusia menjalani hidup secara seimbang antara material dan

Media in democracy is a public sphere to communi-cation and makes relation, and a same time as public arena to gain information. But, media also could not release from streotypes and tendency that usually bring of interest, either the owner or ideology. It is meaning media can not released from perspective distorsion, values bias and take a side. Media also effective to become propaganda instrument for a political interest and an ideology. It is seen like how media in US, for example, stereotype of Islam in discourses contradiction and glob-al interest opposition. Then, Islam dominantly identified as doctrine teaches radicalism, fundamen-talism and terorism. Thus, it is often be justification for US to operate the military mission in the name of democracy. Tak dipungkiri pers atau media menjadi salah satu pilar bagi demokrasi. Media dalam demokrasi adalah sebagai ruang bagi publik berkomunikasi dan berinteraksi, sekaligus sarana publik mem-peroleh informasi tentang banyak hal. Namun, media juga tak bisa dilepaskan dari stereotip dan kecenderungan-kecenderungan, yang biasanya membawa kepentingan, baik pemilik maupun ide-ologi. Media karenanya tak lepas dari distorsi perspektif, bias nilai dan berpihak. Media juga efektif menjadi alat propaganda bagi sebuah kepentingan politik dan ideologi, seperti bagaimana media di negara Amerika, misalnya, menstereotipkan Islam dalam analisis pertentangan wacana dan kepent-ingan global. Sehingga, dominan Islam diidentikkan dengan sematan sebagai ajaran yang mengajarkan radikalisme, fundamentalisme dan terorisme. Karenanya pula seringkali menjadi alasan pembenar bagi Amerika untuk menjalankan misi militer atas nama demokrasi.

    Full Text Available Menjadi seorang musisi tidak sekedar bermain musik atau menyanyi saja. Ada jenjang-jenjang yang akan dilewatidalam dunia musik, yang pada akhirnya setiap musisi dihadapkan kepada tanggung jawab dalam dunia tersebut. Di jaman ini, jika jenjang seorang musisi sudah tahap profesional, maka musik dan bisnis merupakan hal yang tidak terpisahkan. Jadi tidak heran jika ada banyak orang yang memimpikan untuk berkarier dalam bidang musik, bahkan telah men1adicita-cita sejak kecil.Jadi penting bagi musisi gerejawi benar-benar "mengkotakkan dirinya" terhadap persepsi yang dianut oleh musisi sekuler, bukan mencampurkannya. Hal ini sangat esensial, karena musisi gerejawi bukan melayani manusia melainkan oleh anugerah Tuhan dipercayakan pekerjaan ini. Dengan demikian pelayanan sebagai musisi gerejawi tidak tercemar oleh persepsi dari dunia musik sekuler. Selain itu musisi gerejawi dapat merefleksikan Tuhan yang disembahnya kepada dunia sekuler, karena tujuan dari semua yang dilakukannya adalah untuk kemuliaan nama Tuhan.

The paw withdrawal threshold (PWT, paw edema, and Phosphor-p38MAPK-Immunoreactivity (p-p38MAPK-IR cells were measured before (0 h and at 1, 3, 5, 7, 25, and 73 h after CFA or saline injection. EA increased PWT at 1, 3, 25, and 73 h and inhibited paw edema at 25 and 73 h after CFA injection. Moreover, the increasing number of p-p38MAPK-IR cells which was induced by CFA was suppressed by EA stimulation in PAG and RVM at 3 and 5 h and in SCDH at 5, 7, 25, and 73 h. These results suggest that EA suppresses inflammation-induced hyperalgesia probably through inhibiting p38MAPK activation in the descending facilitatory pathway.

    Although activation of the lysophosphatidic acid receptor 1 (LPA1) is known to mediate pronociceptive effects in peripheral pain models, the role of this receptor in the modulation of spinal nociception following spinal cord injury (SCI) is unknown. In this study, LPA1 regulation of spinal excitability mediated by supraspinal descending antinociceptive control systems was assessed following SCI in both wild-type (WT) and maLPA1-null receptor mice. The effect of a T8 spinal compression in WT and maLPA1-null mice was assessed up to 1 month after SCI using histological, immunohistochemical and behavioural techniques analysis including electrophysiological recording of noxious toes-Tibialis Anterior (TA) stimulus-response reflex activity. The effect of a T3 paraspinal transcutaneous electrical conditioning stimulus on TA noxious reflex temporal summation was also assessed. Histological analysis demonstrated greater dorsolateral funiculus damage after SCI in maLPA1-null mice, without a change in the stimulus-response function of the TA noxious reflex when compared to WT mice. While T3 conditioning stimulation in the WT group inhibited noxious TA reflex temporal summation after SCI, this stimulus strongly excited TA reflex temporal summation in maLPA1-null mice. The functional switch from descending inhibition to maladaptive facilitation of central excitability of spinal nociception demonstrated in maLPA1-null mice after SCI was unrelated to a general change in reflex activity. These data suggest that the LPA1 receptor is necessary for inhibition of temporal summation of noxious reflex activity, partly mediated via long-tract descending modulatory systems acting at the spinal level. © 2015 European Pain Federation - EFIC®

    Masyarakat Singkawang adalah masyarakat yang terdiri atas berbagai kelompok suku bangsa dan agama. Secara historis, masyarakat Singkawang mampu mem­pertahankan harmoni antar agama. Model interaksi sosial yang bersifat asosiatif tampaknya potensial untuk mendukung harmoni di dalam masyarakat. Ber­dasarkan paradigma fungsional-struktural, masyarakat diasumsikan sebagai sistem organik yang memiliki huungan antar bagiannya untuk mempertahankan masyarakat. Interaksi sosial di dalam masyarakat Singkawang dikembangkan melalui interaksi di dalam lingkup keluarga, lingkungan sekitar, aktifitas ekonomi, para pimpinan agama, dan hubungan di dalam lingkup budaya dan tradisi. Meskipun demikian, hubungan antar unsur masyarakat masih kosmopolitan, yang di dalamnya anggota masyarakat kurang aktif dalam mengembangkan harmoni masyarakat.

    C’est bien connu, les étudiants universitaires francophones préfèrent écrire dans leur langue maternelle. Voilà pourtant qu’on leur recommande de publier leurs résultats de recherche dans des revues savantes anglaises. L’effort supplémentaire en vaut-il la peine ? Absolument ! Pour rejoindre la communauté scientifique, il faut en maîtriser la langue. Et ce n’est pas tout. En plus d’être rédigé en anglais, votre article devra être clair, bien écrit et impeccablement structuré pour passer l’épreuve de la révision scientifique, puis être enfin publié dans une revue respectable. Commencez-vous à sentir la pression ? Vous vous apercevrez que l’anglais scientifique est un langage particulier que même les anglophones doivent acquérir. L’anglais des sciences n’est pas exactement la langue de Shakespeare dans sa forme et ses fonctions; je préfère l’appeler la langue de Darwin.

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

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

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

Justeru, kertas kerja ini akan mengupas serba ringkas mengenai konsep EK dari perspektif Islam dan Barat, dengan melihat kepada beberapa titik persamaan dan perbezaan antara kedua-dua pandangan. Islam dan Barat bersetuju bahawa individu yang memiliki EK yang tinggi merupakan individu yang berfikiran positif, berani mengambil risiko dan tidak mudah berputus. Namun pandangan Islam terhadap konsep ini lebih luas, kerana Islam mengaitkan konsep ini dengan konsep tauhid uluhiyyah dan konsep manusia sebagai ahsan al-taqwim. Oleh demikian, EK dari perspektif Islam lebih bersifat kekal dan umum, di samping individu yang berefikasi tinggi menurut Islam ialah individu yang memiliki sifat sabar, syukur, redha dan redha.

    This study aimed to describe the prevalence of physical activity (PA) and associated factors in various domains (leisure-time, work, home, and commuting) among quilombolas (descendants of African slaves) in Bahia State, Brazil. This was a cross-sectional study of 797 individuals from 18 to 100 years of age. The study adopted a cutoff point of 150 minutes of PA per week. A hierarchical Poisson model was used. The highest prevalence of PA was at work (42.1%), followed by the home environment (39.3%), commuting (35.5%), and leisure time (13.1%). PA at work was associated with male gender, lower age, higher schooling, and consumption of alcohol and fruits. PA in the household domain was associated with female gender, lower age, marital status (married), and negative self-rated health. In commuting, PA was associated with male gender and lower age bracket, and during leisure time with safety, male gender, lower age, and higher schooling. The study concludes that this slave-descendant community displays a profile of PA that is characteristic of rural groups (more active at work, with little leisure-time activity). The determinants of PA were similar to those seen in urban groups.

A cross-sectional study was conducted in a community of Ghawarna between March and June 2013 in Ghawr Al-Mazraa Village in the southern part of the Jordan Valley. A total of 517 participants, aged >25 years, were randomly selected using cluster random sampling technique. Data were collected using an interviewer-administrated questionnaire and on-location measurement of blood pressure (BP), height, and weight. Prevalence rates were compared by sex and age groups using chi-square test while backward selection logistic regression analysis was used to identify predictors of HTN. We found 229 (44.3%) of the 517 participants had HTN. Of those 229 hypertensives, 146 (28.2%) participants were discovered to have HTN for the "first time." Only 23 of the 83 who were aware of their hypertension had their BP controlled. When we added the undiagnosed HTN (n=146) to the uncontrolled HTN (n=60), the prevalence of uncontrolled HTN became 90% (206/229). Older age, higher BMI, diabetes mellitus, and dyslipidemia were associated with having HTN. HTN prevalence, awareness and control levels are alarming among Ghawarna.

    Full Text Available Study on daytime descending intermediate layer over subtropical Indian station Waltair (17.7° N, 83.3° E geographic, 6.4° N, 10° E geomagnetic, 20° N dip located in the equatorial anomaly transition region, using an IPS 42 Digital Ionosonde during the low solar activity year 2004 showed that the layers occur in the altitude range of 140–160 km with maximum occurrence during winter solstice. The layers observed during daytime occur with a double peak variation throughout the year with less occurrence probability and shorter duration presence during forenoon hours. The morning layer descent was associated with a density increase where as during afternoon hours a decrease in density was observed. The downward drift velocity was about 8 km/h during morning hours and between 7–11 km/h during afternoon hours, with a low descent rate of around 4.5 km/h during summer morning hours. The results indicate the presence of a 6 h tide at this location as observed from the characteristics of the descending layers, unlike at majority of locations where a significant semi diurnal trend is observed. The study brings out the complex nature of the tidal interaction at different locations.

    Thymic stromal lymphopoietin (TSLP) has been linked as a susceptibility gene for the development of allergic diseases. It is known that the population of Cartagena is a triethnic mix, in which the component of African ancestry was significantly associated with risk of asthma and high total serum IgE levels. This component comes from African slaves brought into the continent and settled in "palenques", one of them is San Basilio de Palenque, in the Colombian Caribbean Coast. To analyze the distribution of single nucleotide polymorphisms (SNP) rs1837253, rs17551370 and rs2289276 located in TSLP gene, in the African-descendent population of San Basilio de Palenque. By real time-PCR and probes TaqMan SNP Genotyping™, we genotyped three polymorphisms in 80 individuals of African-descent aged 5 to 18 years of age. The frequency of the rs1837253 allele T was 41.9%, for the allele A, 14.3% for rs17551370, and 22.5% for the allele T of rs2289276. The rs17551370 and rs2289276 distribution remained in Hardy- Weinberg genetic equilibrium. The allele frequency of each SNP did not show statistically significant differences with those reported for other African and African-descendent populations. The three polymorphisms in the TSLP were present in the sample population of San Basilio de Palenque and its distribution is similar to that reported for African populations and African ancestry in America.

    Selection of ideal recipient vessels is one of the most important factors determining success in free-flap reconstruction of the lower limb. At the knee, the choice of vessels has traditionally been either the common femoral or the popliteal vessels and their branches but these are often difficult to use or cannot be used. A series of 32 free flaps for cover of complex injuries of the knee involving the distal femur, the knee joint and the upper tibia were reconstructed using the descending genicular branch of the femoral artery in the adductor canal and its muscular branches to the vastus medialis as the recipient vessels. All but one flap survived with no major complications. The use of the descending genicular artery as the recipient vessel for reconstruction with free flaps around the knee has various advantages including: (i) it is mostly remote from the zone of trauma, (ii) it is constant in location, (iii) the recipient vessels are an excellent size match for end-to-end anastomosis, (iv) there is no need for changes of position of the patient when using most free flaps commonly used for knee reconstruction, (v) it is easy to harvest these simultaneously, (vi) secondary exposure of the underlying skeleton from all quadrants is unlikely to divide the flap pedicle as it is superior and (vii), perhaps most important of all, it obviates the need for exploration of the popliteal fossa.

    We report our experience with extended right hemicolectomy (ERH) and left hemicolectomy (LH) for the treatment of cancers located between the distal transverse and the proximal descending colon, and compare postoperative morbidity, mortality, pathological results and survival for the two techniques. A retrospective review was performed of a single institution series over ten years. Patients who underwent different operations, had benign disease or received palliative resections were excluded. Data collected were patient demographics, type and duration of surgery, tumour site, postoperative complications and histology results. Ninety-eight patients were analysed (64 ERHs, 34 LHs). ERH was conducted using an open approach in 93.8% of cases compared with 73.5% for LH. The anastomotic leak rate was similar for both groups (ERH: 6.3%, LH: 5.9%). This was also the case for other postoperative complications, mortality (ERH: 1.6%, LH: 2.9%) and overall survival (ERH: 50.4 months, LH: 51.8 months). All but one patient in the ERH cohort had clear surgical margins. Nodal evaluation for staging was adequate in 78.1% of ERH cases and 58.8% of LH cases. In our experience, both ERH and LH are adequate for tumours located between the distal transverse and the proximal descending colon.

    The aim of the study was to examine the external knee adduction moments in a group of older and younger adults while descending stairs and thus the possibility of an increased risk of knee osteoarthritis due to altered knee joint loading in the elderly. Twenty-seven older and 16 younger adults descended a purpose-built staircase. A motion capture system and a force plate were used to determine the subjects' 3D kinematics and ground reaction forces (GRF) during locomotion. Calculation of the leg kinematics and kinetics was done by means of a rigid, three-segment, 3D leg model. In the initial portion of the support phase, older adults showed a more medio-posterior GRF vector relative to the ankle joint, leading to lower ankle joint moments (Pstairs by using the trailing leg before the initiation of the double support phase more compared to the younger ones. The consequence of this altered control strategy while stepping down is a more medially directed GRF vector increasing the magnitude of external knee adduction moment in the elderly. The observed changes between leading and trailing leg in the elderly may cause a redistribution of the mechanical load at the tibiofemoral joint, affecting the initiation and progression of knee osteoarthritis in the elderly.

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

  8. Entre infini et extravagance : le romantisme français dans l’épistolaire de Juan María Gutiérrez

    Ana Eugenia Vázquez

    2016-12-01

    Full Text Available Cet article a pour but d’analyser les figures de lecteurs construites par Florencio Varela et Mariquita Sánchez de Thompson dans les lettres qu’ils écrivent à Juan María Gutiérrez vers le début de l’année 1840. Les expériences de lecture représentées renvoient toujours aux auteurs romantiques français comme Victor Hugo ou George Sand. Or la réception du romantisme se conçoit différemment dans chaque cas : Mariquita se montre comme une lectrice romantique, sensible et enthousiaste, lisant pour s’identifier avec la vie et le destin tragique de ses auteurs préférés. Florencio Varela réprouve en revanche l’excès passionnel des pièces d’Hugo. Cette opposition reflète les dissidences que le romantisme européen, plus radical dans ses propositions esthétiques et politiques que le romantisme local, a posé pour une génération qui commençait à projeter la création d’une littérature national.

    Full Text Available Dans cet article nous examinons la réception dе Madame de Genlis chez plusieurs auteurs russes du XIXe siècle. Pouchkine la nomma « écrivailleuse sans talent », malgré le fait que ses Mémoires suscitaient son grand intérêt. Léon Tolstoï utilisa le nom de Madame de Genlis dans Guerre et Paix pour mettre en relief le caractère de ses protagonistes : Koutouzov et Vé-ra Rostova. Leskov écrivit un petit chef-d'oeuvre, L’Esprit de Madame de Genlis, sur sa déifica-tion dans la haute société. La réception de Madame de Genlis en Russie paraît étroitement liée au statut aristocratique de son oeuvre, qui servit ainsi de modèle culturel aux élites fran-cophiles russes.

    The kinetics and mechanisms of the reaction of pure or low alloyed magnesium with various gas saturated by water vapor: oxygen, argon, nitrogen, air, carbon dioxide, have been studied and compared in the temperature range 350-600 deg C. After picturing the large chemical reactivity of magnesium surface, the more or less properties of the oxide film, always made of magnesia, have been shown depending on the nature of the gas carrying water vapor; in fact, metal sublimation occurs the more easily as the surrounding atmosphere is less oxidizing. Moreover, an activation energy change is systematic, but at a temperature which depends also on the latter. In the case of the alloys, the linear oxidation rate is generally obtained only after short induction periods, parabolic in nature. Two possibilities of corrosion inhibition of magnesium by water vapor are then demonstrated and explained: either by a partial superficial fluoridation, or when the carrier gas is carbon dioxide. Also, the extreme conditions of oxidation were studied, that is the ignition processes that occur at a particular temperature in every gas mixture. Finally, it is tried to evolve the fundamental and practical significance of all the results.

Control system use was on open loop type based on timer. The performance test of drive system was focused on electrical energy consumption and rotational speed of the system that was measured by multifunctional mini ammeter and tachometer. The control system was tested during 4 days, to evaluate their performances between set point and actual timing while filling water tank and rotate the system at maximal load condition. Electrical power consumption was 208 W at average rotational speed 2703 rpm. Increasing load caused an increase of energy consumption but made the drive rotation decline. The position control performance had on position error around 50 cm. Consequently, setting time on timer must be adjusted.

    After having given an overview of research works in biophysics and biochemistry related to the study of the auxinic action within a cell, this research thesis reports the use of radio-auto-histography to detect the βindolylacetic acid within tissues and within a cell. The author reports experiments performed by using this acid either in its normal status, or marked either with carbon 14 or with tritium. Growth tests have been performed by using different plants. The author also presents insolubilization techniques which have been applied to the acid for this study. In vivo tests have been performed with the radioactive acid and other precipitation compounds (lead acetate, mercury nitrate). The acid detection technique is presented, and results are discussed [French] Dans le but de detecter, par radioautohistographie, l'acide β-indolylacetique marque au tritium et ses derives metaboliques, nous avons mis au point des techniques nouvelles d'insolubilisation de l'A.I.A. L'acide picrique et l'acetate de plomb donnant avec l'auxine un precipite insoluble dans les liquides de fixation (Formol neutre-Liquide de Bouin) et d'inclusion, nous avons reussi a conserver dans des epicotyles de pois et de haricot, des racines de feve et de pois, des coleoptiles d'avoine, une importante fraction de l'A.I.A. marque fourni a ces tissus (a des concentrations superieures ou egales a 10 mg/l). Cette detection etant satisfaisante, nous avons essaye de localiser l'A.I.A. et ses derives, avec plus de precision, dans la cellule en particulier. Mais il fallait alors tenir compte de plusieurs causes d'erreur possible: l'effet nocif eventuel du liquide precipitant (acide picrique ou acetate de plomb), - la diffusion d'A.I.A. dans ce liquide, - la cytologie imparfaite et en particulier l'incertitude sur la limite vacuole-cytoplasme. Compte tenu de ces critiques, il nous semble que la radioactivite (due a la presence d'A.I.A. et des produits derives) se localise plus particulierement au

    Full Text Available Dans cet article, nous étudions la figure de la sorcière dans Moi, Tituba sorcière… de Maryse Condé afin de voir comment elle dialogue avec les discours postcoloniaux et féministes de l’époque. Nous analysons d’abord l’intertextualité construit dans le roman avec la pièce d’Arthur Miller Les sorcières de Salem en regardant comment Condé transforme les événements qui ont eu lieu à Salem en 1692 et comment elle réhabilite le personnage de Tituba. Nous nous penchons ensuite sur la figure de la sorcière et des marginaux dans le texte en vue de comprendre sa construction protéiforme et ses points de contact avec les discours ambiants.

Les traits observables les plus saillants sont ceux de la morphologie graphique, mais il n’en reste pas moins que certains jeunes utilisent des lexiques particuliers dans les blogs qui méritent une attention particulière. Nous nous proposons donc d’étudier les différents lexiques utilisés par des jeunes de 12 à 22 ans dans les blogs de la plateforme skyrock.com aux niveaux de sa diversité, de ses usages sémantiques variable d’un scripteur à l’autre pour un même mot, et de ses particularités morphosyntaxiques.

Ainsi, nous analyserons des lexiques variés dans leurs usages écrits tels que bolos, bédave, gérer, ouf, tigen, ou encore des lexiques empruntés tels que mouv, full, etc., ainsi que des emplois particuliers de séquences autonomes comme lol. Quelques questions périphériques complèteront notre analyse telle que celles qui concerne l’influence des usages lexicaux entre pairs et le savoir partagé, la distinction de différentes communautés en fonction des lexiques utilisés, ou encore la variabilité des représentations graphiques d’un même mot.

    The 2013 earthquake is the largest that occurred in the last four decades along the western part of the Hellenic subduction zone, causing light damage in western Crete. Since rupture dimensions and properties of subduction events are in general more difficult to estimate due to their position in relation with seismological networks geometry, its occurrence provides an opportunity to investigate its rupture characteristics as in detail as possible, and consequently to shed more light in the geometry of the descending slab. The western almost rectilinear part of the convergent front accommodated the great 365 AD Mw8.3 earthquake, the largest event ever reported in the Mediterranean region, generating a tsunami that affected almost its entire eastern part. The oceanic plate of eastern Mediterranean, the front part of the northward moving African lithospheric plate, is subducting northeasterly beneath the Aegean microplate, the southern portion of Eurasian lithospheric plate in this area, at a rate of 4.5 cm/yr, frequently accommodating large destructive earthquakes with magnitudes M>6.5 along the main thrust zone. Historical and instrumental information reveals that strong (M>6.0) earthquakes, both shallow and intermediate ones are frequent in the area, although there is not any reference to any other such strong event. Plate motion is far above the manifestation of seismicity, probably due to the fact that the seismic coupling coefficient at this plate boundary has been estimated at approximately 10% or less. The main shock is associated with a fault patch onto the coupled part of the overriding and descending plates, with the compression axis being oriented in the direction of plate convergence. The first 10-days relocated seismicity shows activation of the upper part of the descending slab, with most activity being concentrated between 10 and 30 km, with the main shock being located at the bottom of the activated segment.

    Full Text Available Rapid change of environment is an external force that causes the organization to transform. Fundamentally, the main purpose of the transformation is to change the organizational structure to be more flexible and competitive with fewer hierarchial levels, managers, and employees. The transformation needs to be radical, causing resistance from the organization's members. Their resistance can cause the transformation to fail, therefore organization must find ways to lessen this resistance. First, organization must learn about the diversity of its members' cultures and values. Second, organization must build its own organizational culture which can support the success of the transformation, by communicating it with the members of the organization. To support organizational culture building efforts, it needs changes in human resources practices, especially recruitment and selection. Abstract in Bahasa Indonesia : Perubahan yang cepat dalam lingkungan merupakan kekuatan eksternal yang mengakibatkan transformasi dalam sebuah organisasi. Pada dasarnya, tujuan utama dari transformasi tersebut adalah merubah struktur organisasi agar menjadi lebih fleksibel dan mampu bersaing, dengan tingkat structural yang sedikit, serta jumlah manajer dan karyawan yang lebih kecil. Transformasi tersebut harus menyeluruh, dan hal ini dapat menyebabkan resistensi dari para anggota organisasi yang memperhambat perubahan tersebut. Resistensi itu bisa menyebabkan perubahan tersebut batal, oleh karena itu organisasi harus mencari jalan untuk mengurangi hambatan-hambatan tersebut. Pertama, organisasi harus belajar keanekaragaman dari budaya dan nilai anggotanya. Kedua, organisasi harus mengembangkan budaya organisasi sendiri melalui komunikasi yang baik dengan anggotanya. Untuk mendukung usaha mengembangkan budaya organisasi, harus ada perubaban pada kebijakan sumber daya manusia, terutama dalam rekrutmen dan seleksi karyawan. Kata kunci: transformasi, resistensi, budaya

    Full Text Available L’une des preuves de l’universalité « de tous les temps » (Ben Jonson de Shakespeare est que ses pièces ont aussi été adaptées dans presque tous les pays de ce monde, que ce soit sous leur forme quasi-historique ou au cours d’un échange intertextuel libre de versions hybrides. L’émergence d’une conscience post-coloniale dans de nombreux points du monde a produit une ré-interprétation critique de ses œuvres dans le sens d’une réévaluation émancipatrice qui transforme les prétextes shakespeariens de façon le plus souvent créatrice en tentant d’attirer l’attention du public. La variété des interprétations possibles peut être illustrée par le cas du Canada, qui n’est pas tant un pays post-colonial mais plutôt un pays de colons, au moyen de trois exemples de pièces contemporaines : Ken Mitchell, Cruel Tears (1977, Anne-Marie MacDonald, Goodnight Desdemona (Good Night Juliet (1990, et Ken Grass, Claudius (1993.

Decentralized cooperation can be complementary but its conditions for success depend, among other things, on the success of decentralization processes in the South.

Mereka bekerja sama dalam aksi penyerobotan tanah petani, pendirian perkebunan-perkebunan dan dalam menghadapi gerakan protes petani. Negara bukan hanya menghadapi gerakan perlawanan petani dengan represi-represi fisik. Secara sistematis negara juga melakukan propaganda dengan menciptakan gambaran-gambaran yang unfavourable tentang petani pelaku penjarahan dalam berbagai representasi wacana. Dalam batas tertentu, media massa justru memperkuat kecenderungan ini dengan menonjolkan dimensi kekerasan, pemberontakan dan anarkisme dalam mewacanakan aksi-aksi penjarahan petani.

    Full Text Available Abstract With the proliferation of minimally invasive cardiac surgery a number of alternative inflow sites for coronary artery bypass grafting have been utilized, especially in higher risk patients. The use of axillary-coronary artery bypass is a safe and effective alternative especially in the case of patients requiring redo coronary revascularization. However, the length and convoluted course of the axillary-coronary vein graft makes is susceptible to twisting, trauma and neointimal hyperplasia. We therefore report a case of an axillary-coronary artery bypass in a high risk patient in which a Dacron conduit was used to externally support and protect the vein graft to the left anterior descending artery. Surgical technique and considerations are presented and discussed.

  8. Mean blood velocities and flow impedance in the fetal descending thoracic aortic and common carotid artery in normal pregnancy.

    Science.gov (United States)

    Bilardo, C M; Campbell, S; Nicolaides, K H

    1988-12-01

    A linear array pulsed Doppler duplex scanner was used to establish reference ranges for mean blood velocities and flow impedance (Pulsatility Index = PI) in the descending thoracic aorta and in the common carotid artery from 70 fetuses in normal pregnancies at 17-42 weeks' gestation. The aortic velocity increased with gestation up to 32 weeks, then remained constant until term, when it decreased. In contrast, the velocity in the common carotid artery increased throughout pregnancy. The PI in the aorta remained constant throughout pregnancy, while in the common carotid artery it fell steeply after 32 weeks. These results suggest that with advancing gestation there is a redistribution of the fetal circulation with decreased impedance to flow to the fetal brain, presumably to compensate for the progressive decrease in fetal blood PO2.

    Full Text Available Pour la mésopotamie d'entre Prut et Nistru on connait 99 points encadrées dans la prémiere phase de développement, l'étape Cucuteni A. De ce nombre, seulement 14 ont déjà été étudiés. Les premières investigations dans un établissement cucutenien dans l'interfluve Prut-Dniestr ont été organisée en 1893 à Şipeniţ, Bucovine et ils continuent, avec quelques interruptions, jusqu'à nos jours. Dans les stations où des fouilles considérables ont été déployés ont été identifiées des fortifications. Il s'agit des restes d'établissements situées dans des lieus naturellement fortifiées, traces des logements enterées or construites sur la surface. L'habitat cucutenien de l'étape A du territoire de la Moldavie, sous tous ses aspects, s'intègre parfaitement équilibré dans la complex Ariusd-Cucuteni-Tripolye, apportant une note personnelle et spécifique à cette grande civilisation.

  11. Conductivite dans le modele de Hubbard bi-dimensionnel a faible couplage

    Science.gov (United States)

    Bergeron, Dominic

    Le modele de Hubbard bi-dimensionnel (2D) est souvent considere comme le modele minimal pour les supraconducteurs a haute temperature critique a base d'oxyde de cuivre (SCHT). Sur un reseau carre, ce modele possede les phases qui sont communes a tous les SCHT, la phase antiferromagnetique, la phase supraconductrice et la phase dite du pseudogap. Il n'a pas de solution exacte, toutefois, plusieurs methodes approximatives permettent d'etudier ses proprietes de facon numerique. Les proprietes optiques et de transport sont bien connues dans les SCHT et sont donc de bonne candidates pour valider un modele theorique et aider a comprendre mieux la physique de ces materiaux. La presente these porte sur le calcul de ces proprietes pour le modele de Hubbard 2D a couplage faible ou intermediaire. La methode de calcul utilisee est l'approche auto-coherente a deux particules (ACDP), qui est non-perturbative et inclue l'effet des fluctuations de spin et de charge a toutes les longueurs d'onde. La derivation complete de l'expression de la conductivite dans l'approche ACDP est presentee. Cette expression contient ce qu'on appelle les corrections de vertex, qui tiennent compte des correlations entre quasi-particules. Pour rendre possible le calcul numerique de ces corrections, des algorithmes utilisant, entre autres, des transformees de Fourier rapides et des splines cubiques sont developpes. Les calculs sont faits pour le reseau carre avec sauts aux plus proches voisins autour du point critique antiferromagnetique. Aux dopages plus faibles que le point critique, la conductivite optique presente une bosse dans l'infrarouge moyen a basse temperature, tel qu'observe dans plusieurs SCHT. Dans la resistivite en fonction de la temperature, on trouve un comportement isolant dans le pseudogap lorsque les corrections de vertex sont negligees et metallique lorsqu'elles sont prises en compte. Pres du point critique, la resistivite est lineaire en T a basse temperature et devient

    2015-06-01

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

  4. The View from the Trees: Nocturnal Bull Ants, Myrmecia midas, Use the Surrounding Panorama While Descending from Trees.

    Solitary foraging ants commonly use visual cues from their environment for navigation. Foragers are known to store visual scenes from the surrounding panorama for later guidance to known resources and to return successfully back to the nest. Several ant species travel not only on the ground, but also climb trees to locate resources. The navigational information that guides animals back home during their descent, while their body is perpendicular to the ground, is largely unknown. Here, we investigate in a nocturnal ant, Myrmecia midas , whether foragers travelling down a tree use visual information to return home. These ants establish nests at the base of a tree on which they forage and in addition, they also forage on nearby trees. We collected foragers and placed them on the trunk of the nest tree or a foraging tree in multiple compass directions. Regardless of the displacement location, upon release ants immediately moved to the side of the trunk facing the nest during their descent. When ants were released on non-foraging trees near the nest, displaced foragers again travelled around the tree to the side facing the nest. All the displaced foragers reached the correct side of the tree well before reaching the ground. However, when the terrestrial cues around the tree were blocked, foragers were unable to orient correctly, suggesting that the surrounding panorama is critical to successful orientation on the tree. Through analysis of panoramic pictures, we show that views acquired at the base of the foraging tree nest can provide reliable nest-ward orientation up to 1.75 m above the ground. We discuss, how animals descending from trees compare their current scene to a memorised scene and report on the similarities in visually guided behaviour while navigating on the ground and descending from trees.

    Purpose: To use 4-dimensional computed tomography (4D-CT) imaging to predict the level of uncertainty in cardiac dose estimates of the left anterior descending artery that arises due to breathing motion during radiation therapy for left-sided breast cancer. Methods and Materials: The fast helical CT (FH-CT) and 4D-CT of 30 left-sided breast cancer patients were retrospectively analyzed. Treatment plans were created on the FH-CT. The original treatment plan was then superimposed onto all 10 phases of the 4D-CT to quantify the dosimetric impact of respiratory motion through 4D dose accumulation (4D-dose). Dose-volume histograms for the heart, left ventricle (LV), and left anterior descending (LAD) artery obtained from the FH-CT were compared with those obtained from the 4D-dose. Results: The 95% confidence interval of 4D-dose and FH-CT differences in mean dose estimates for the heart, LV, and LAD were ±0.5 Gy, ±1.0 Gy, and ±8.7 Gy, respectively. Conclusion: Fast helical CT is a good approximation for doses to the heart and LV; however, dose estimates for the LAD are susceptible to uncertainties that arise due to intrafraction breathing motion that cannot be ascertained without the additional information obtained from 4D-CT and dose accumulation. For future clinical studies, we suggest the use of 4D-CT–derived dose-volume histograms for estimating the dose to the LAD.

    PurposeTo evaluate the safety, feasibility, and patency rates of radiologic placement of uncovered stents for the treatment of malignant colonic obstruction proximal to the descending colon.Materials and MethodsThis was a retrospective, single-center study. From May 2003 to March 2015, 53 image-guided placements of uncovered stents (44 initial placements, 9 secondary placements) were attempted in 44 patients (male:female = 23:21; mean age, 71.8 years). The technical and clinical success, complication rates, and patency rates of the stents were also evaluated. Technical success was defined as the successful deployment of the stent under fluoroscopic guidance alone and clinical success was defined as the relief of obstructive symptoms or signs within 48 h of stent deployment.ResultsIn total, 12 (27.3 %) patients underwent preoperative decompression, while 32 (72.7 %) underwent decompression with palliative intent. The technical success rate was 93.2 % (41/44) for initial placement and 88.9 % (8/9) for secondary placement. Secondary stent placement in the palliative group was required in nine patients after successful initial stent placement due to stent obstruction from tumor ingrowth (n = 7) and stent migration (n = 2). The symptoms of obstruction were relieved in all successful cases (100 %). In the palliative group, the patency rates were 94.4 % at 1 month, 84.0 % at 3 months, 64.8 % at 6 months, and 48.6 % at 12 months.ConclusionsThe radiologic placement of uncovered stents for the treatment of malignant obstruction proximal to the descending colon is feasible and safe, and provides acceptable clinical results.

    In this paper, we hypothesize that the biaxial mechanical properties of the aorta may be dependent on arterial location. To demonstrate any possible position-related difference, our study analyzed and compared the biaxial mechanical properties of the ascending thoracic aorta, descending thoracic aorta and infrarenal abdominal aorta stemming from the same porcine subjects, and reported values of constitutive parameters for well-known strain energy functions, showing how these mechanical properties are affected by location along the aorta. When comparing ascending thoracic aorta, descending thoracic aorta and infrarenal abdominal aorta, abdominal tissues were found to be stiffer and highly anisotropic. We found that the aorta changed from a more isotropic to a more anisotropic tissue and became progressively less compliant and stiffer with the distance to the heart. We observed substantial differences in the anisotropy parameter between aortic samples where abdominal samples were more anisotropic and nonlinear than the thoracic samples. The phenomenological model was not able to capture the passive biaxial properties of each specific porcine aorta over a wide range of biaxial deformations, showing the best prediction root mean square error ε=0.2621 for ascending thoracic samples and, especially, the worst for the infrarenal abdominal samples ε=0.3780. The micro-structured model with Bingham orientation density function was able to better predict biaxial deformations (ε=0.1372 for ascending thoracic aorta samples). The root mean square error of the micro-structural model and the micro-structured model with von Mises orientation density function were similar for all positions. Copyright © 2017 Elsevier Ltd.

    Mariana Furquim da Silva Martins

    Full Text Available Furnas do Dionísio is a Brazilian Afro-descendant settlement in the city of Jaraguari, 21.4 miles from Campo Grande, Mato Grosso do Sul, Brazil. Approximately 96 families live in this quilombola (Maroon settlement, also known in Brazil as a remnant community of descendants of African slaves. Recent studies found 20% of households were infested by triatomines, 18% of insects captured in the community were infected by Trypanosoma cruzi, and 22.7% of dogs presented T. cruzi antibodies. The low prevalence of Chagas disease observed in humans in Mato Grosso do Sul State is attributed to its arrival via colonist migration and subsequent transplacental transmission. In order to gain a better understanding of the T. cruzi cycle in residents of the study community, serological and molecular tests were carried out to diagnose Chagas disease. In the present study, 175 residents between 2 and 80 years old were included. A total of 175 participants were interviewed and 170 provided blood samples, which were tested for T. cruzi antibodies with serological tests. Molecular diagnosis was performed in 167 participants by PCR (KDNA and NPCR (satellite DNA tests. One of the 170 samples tested positive for all serological tests performed. The overall frequency of Chagas disease in the community was low (0.6%. Interview responses revealed that 66.3% knew of triatomine insects and 65.7% reported having had no contact with them. Physical improvements to residences, together with vector surveillance and control by the State and municipal governments and local ecological conservation contribute to the low frequency of the Chagas disease in this quilombola community.

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

    La pratique des calculs de rentabilité avec shadow interest se développe depuis quelques années dans les entreprises pétrolières, principalement dans le secteur exploration et développement des gisements. L'objet de cet article est de replacer cette approche parmi les méthodes classiques (calculs de rentabilité globale et de rentabilité des capitaux propres). Une relation simple entre les revenus actualisés relatifs à chacune des approches est obtenue sous certaines hypothèses simplificatrice...
