    2013-11-01

    Full Text Available La durée de vie des disques de frein pour applications poids lourds peut être limitée par une fissuration prématurée induite par les sollicitations thermomécaniques subies par le disque en condition de freinage. La présente étude propose une réponse matériau basée sur la modification de la morphologie du graphite. Le comportement des matériaux innovés est comparé en condition de freinage et de fatigue thermique à celui d'une fonte à graphite lamellaire utilisée en service. The truck brake disc lifespan can be limited by a premature failure induced by the thermo mechanical solicitations occurring during braking. This study proposes a solution by a material approach consisting in the modification of the graphite morphology. The behavior of evolved materials is tested under braking and thermal fatigue solicitations with comparison to an grey cast iron used in service.

  11. The novel Candida albicans transporter Dur31 Is a multi-stage pathogenicity factor.

    Directory of Open Access Journals (Sweden)

    François L Mayer

    Full Text Available Candida albicans is the most frequent cause of oral fungal infections. However, the exact pathogenicity mechanisms that this fungus employs are largely unknown and many of the genes expressed during oral infection are uncharacterized. In this study we sought to functionally characterize 12 previously unknown function genes associated with oral candidiasis. We generated homozygous knockout mutants for all 12 genes and analyzed their interaction with human oral epithelium in vitro. Eleven mutants caused significantly less epithelial damage and, of these, deletion of orf19.6656 (DUR31 elicited the strongest reduction in pathogenicity. Interestingly, DUR31 was not only involved in oral epithelial damage, but in multiple stages of candidiasis, including surviving attack by human neutrophils, endothelial damage and virulence in vivo. In silico analysis indicated that DUR31 encodes a sodium/substrate symporter with 13 transmembrane domains and no human homologue. We provide evidence that Dur31 transports histatin 5. This is one of the very first examples of microbial driven import of this highly cytotoxic antimicrobial peptide. Also, in contrast to wild type C. albicans, dur31Δ/Δ was unable to actively increase local environmental pH, suggesting that Dur31 lies in the extracellular alkalinization hyphal auto-induction pathway; and, indeed, DUR31 was required for morphogenesis. In agreement with this observation, dur31Δ/Δ was unable to assimilate the polyamine spermidine.

  12. Discipline and credibility in the post-war australopithecine controversy: Le Gros Clark versus Zuckerman.

    2012-01-01

    Paleoanthropologists and outside commentators have often remarked upon the apparent difficulty of securing shared belief among experts in the science of human evolution. The field has been and continues to be particularly prone to disagreement and even controversy among its practitioners to a degree that sets it apart from other areas of scientific inquiry. The fact that the field lies at the intersection of a number of disciplines may help to explain this predicament. Displays of discipline serve as an important resource for scientists as they work to secure credibility. Where a field of inquiry spans a host of disciplinary approaches, there can be disagreement about the kind of disciplined behavior appropriate to making credible claims about that field's subject matter. A conflict of this sort emerged after WW II over the claim that the australopithecines of South Africa represented a likely ancestral link in the evolution of human beings. W. E. Le Gros Clark, working in the established disciplinary tradition of comparative anatomy, endorsed the claim of ancestry, while Solly Zuckerman, reflecting his recent immersion in war-time operations research, criticized that claim on the grounds that it came without the rigorous quantitative demonstration that he felt was the hallmark of a properly disciplined science.

  13. Polyamine uptake by DUR3 and SAM3 in Saccharomyces cerevisiae.

    2007-03-09

    It has been reported that GAP1 and AGP2 catalyze the uptake of polyamines together with amino acids in Saccharomyces cerevisiae. We have looked for polyamine-preferential uptake proteins in S. cerevisiae. DUR3 catalyzed the uptake of polyamines together with urea, and SAM3 was found to catalyze the uptake of polyamines together with S-adenosylmethionine, glutamic acid, and lysine. Polyamine uptake was greatly decreased in both DUR3- and SAM3-deficient cells. The K(m) values for putrescine and spermidine of DUR3 were 479 and 21.2 mum, respectively, and those of SAM3 were 433 and 20.7 mum, respectively. Polyamine stimulation of cell growth of a polyamine requiring mutant, which is deficient in ornithine decarboxylase, was not influenced by the disruption of GAP1 and AGP2, but it was diminished by the disruption of DUR3 and SAM3. Furthermore, the polyamine stimulation of cell growth of a polyamine-requiring mutant was completely inhibited by the disruption of both DUR3 and SAM3. The results indicate that DUR3 and SAM3 are major polyamine uptake proteins in yeast. We previously reported that polyamine transport protein kinase 2 regulates polyamine transport. It was found that DUR3 (but not SAM3) was activated by phosphorylation of Thr(250), Ser(251), and Thr(684) by polyamine transport protein kinase 2.

    The population aging in Brazil and in the world is a reason for an epidemic inquietude. So, the violence against senior people has been considered a problem of public health. This study takes as context the health need of seniors that suffer of violence, aiming to evaluate in a constructive way the Disque Idoso Project in Sobral (Ceará, Brazil). We used Furtado's Constructivist Method of Evaluation, which provides practices of participative evaluation. Trying to reach such perspective, we are guided by paths of the integrative approach (inter, multi and transdisciplinary) and intersectoral. We accomplished the focal groups with representatives of the sections of health, social assistance, justice and senior, the benefited by the project as well as others that contribute to its development. When interacting with the professionals that act in the project headquarters we understood that there is a fear in publishing their work, because there is not structure to enlarge the attendance. The group believes that the efficiency of its actions is limited due to the lack of transport and other professionals. For the professionals of the support social networks, the project should look for intersectoral performance, once it intends to reach a complete attendance. For the seniors, the project is quite valid and needs to be consolidated in the district.

    Full Text Available Abstract: Education which emphasized on cognition domain should be changed by balancing it with skills (psychomotor and attitudes (affective. It is intended that education is able to produce savvy generations who have high moral standards. To that end, KH Abdurrahman Wahid -or better known as Gus Dur- had a concept of character building in education by promoting morality in education. Character building in education is the education which is based on local wisdom. Local wisdom is social norms and values contained in tradition and customs as well as in Islamic teachings that govern how a balance should be established between carrying capacity of the natural environment, lifestyle, and the needs of human beings. In the language of Gus Dur, local wisdom was called the indigenization of Islam in which the teachings of Islam and local traditions were used as a moral basis in the real life of people. Because the cultivation of moral values could be done through education, the local wisdom should be the basic concept of education process. Customs become an integral part in daily life, while religion becomes a way of life to conform to the guidance of Allah. Local wisdom formed from local traditions and locality of religious teachings was able to provide life lessons that were useful for the development process of maturity through the educational process.           الملخص: إن التربية المفضّلة الجانب المعرفي – كما يقع الآن -  لابد من تركها، ويكون البديل هو الموازنة بين الجانب المعرفي والجانب النفسحركي والمهني. والهدف من هذا تخريج الطلاب أو الأجيال الأذكياء المتأدّبين المتخلّقين. وفي هذا كان لكياهي الحاج عبد الرحمن وحيد المعروف بغوسدور فكرة عن التربية الخلقية وهي التربية التي

    Environmental Art works range in scope from major permanent interventions in the landscape to less intrusive, more ephemeral site-specific installations constructed of materials from the local environment. Despite this range of intervention, however, these works all share in a tradition of art making that situates the artwork in direct response to the surrounding landscape. Andy Goldsworthy and Richard Long, for example, both favour methods that combine elements of both sculpture and performance in the creation of non-permanent interventions in the landscape, and both rely upon photographic, text-based, or video documentation as the only lasting indication of the works' existence. Similarly, Earth Scientists are responsible for interventions in the landscape, both physical and conceptual. For example, in Earth science, the periods of the geologic timescale - Cambrian, Ordovician, Silurian, etc. - were established by 19th century pioneers of geology at a time when they were believed to represent natural chapters in Earth history. Since the mid-20th century, stratigraphers have attempted to resolve ambiguities in the original definitions by defining stratotypes: sections of continuously deposited strata where a single horizon is chosen as a boundary. One such international stratotype, marking the Cambrian-Ordovician boundary, is defined at Green Point in Gros Morne National Park, Newfoundland. Boundary|Time|Surface was an ephemeral sculptural installation work constructed in June 2014. The main installation work was a fence of 52 vertical driftwood poles, 2-3 m tall, positioned precisely along the boundary stratotype horizon at Green Point in Newfoundland. The fence extended across a 150 m wave-cut platform from sea cliffs to the low-water mark, separating Ordovician from Cambrian strata. The installation was constructed by hand (with volunteer assistance) on June 22, as the wave-cut platform was exposed by the falling tide. During the remainder of the tidal cycle

    In plants, urea derives either from root uptake or protein degradation. Although large quantities of urea are released during senescence, urea is mainly seen as a short-lived nitrogen (N) catabolite serving urease-mediated hydrolysis to ammonium. Here, we investigated the roles of DUR3 and of urea in N remobilization. During natural leaf senescence urea concentrations and DUR3 transcript levels showed a parallel increase with senescence markers like ORE1 in a plant age- and leaf age-dependent manner. Deletion of DUR3 decreased urea accumulation in leaves, whereas the fraction of urea lost to the leaf apoplast was enhanced. Under natural and N deficiency-induced senescence DUR3 promoter activity was highest in the vasculature, but was also found in surrounding bundle sheath and mesophyll cells. An analysis of petiole exudates from wild-type leaves revealed that N from urea accounted for >13% of amino acid N. Urea export from senescent leaves further increased in ureG-2 deletion mutants lacking urease activity. In the dur3 ureG double insertion line the absence of DUR3 reduced urea export from leaf petioles. These results indicate that urea can serve as an early metabolic marker for leaf senescence, and that DUR3-mediated urea retrieval contributes to the retranslocation of N from urea during leaf senescence.

    Le travail durant ce stage a permis de revoir, toute la gestion de la ferme de calcul sans disques qu'utilise l'expérience LHCb du CERN. Celle-ci est maintenant administrable par l'intermédiaire du logiciel de gestion Quattor et autorise à la fois l'administration du High Level Trigger (HLT) mais également du trigger L0 (contrairement à ce qui était initialement prévu). Cette nouvelle gestion, fortement indépendante des versions du système Linux utilisé, Scientific Linux CERN (SLC), permet le passage des CCPCs de SLC4 à SLC5 très facilement. Un résultat important est l'absence d'utilisation des outils Red Hat pour administer cette ferme, ce qui ouvre la voie à une future migration de l'ensemble de la ferme à SLC6, quand celle-ci sera prête.

    Nd-Pb isotopic geochemistry of metabasalt from Dur'ngoi ophiolite, Qinghai Province, NW China reveals the presence of DMM mixing with EMIl components in its upper mantle source, which is comparable with present Indian MORB. Comparisons indicate that the geochemistry, chronology and source characteristics of Dur'ngoi ophiolite coincide with Paleo-tethyan ophiolites from "Sanjiang" area. Together with evidences from regional geology in adjacent areas, this study proves that independent paleo-tethyan basins evolved contemporarily,the dynamics of which is attributed to the interaction of mantle plume with over-riding lithosphere.

    Full Text Available É proposta uma modificação para o método de Bielschowsky-Gros a ser aplicado em cortes em parafina, utilizável no estudo de terminações nervosas centrais e periféricas. O método é de manipulação fácil e executável em poucas horas, ao contrário da grande maioria de métodos de impregnação em cortes de parafina. A impregnação é precedida de preparador e de mordente e seguida por viragem em ouro. O preparador utilizado é a solução de formol a 2% neutralizada com carbonato de magnésio, adicionada ou não a sonifeno a 1% O emprêgo do sonifeno tem a vantagem de permtir impregnar mais vigorosamente as fibras e terminações nervosas e evitar ao máximo a impregnação das fibras conjuntivas, oferecendo perfeita limpeza da preparação. O mordente é constituído por uma solução recente de nitrato de prata a 10% na qual os cortes permanecem por tempo variável, sendo aconselhável, para a coloração do plexo simpático fundamental, permanência prolongada (cêrca de uma hora. A impregnação é feita em solução de óxido de prata amoniacal preparada como o recomenda Bielchowsky (solução de nitrato de prata a 10% acrescida de amoníaco até completa dissolução do precipitado formado, podendo ser substituída, com idênticos resultados, pelas soluções propostas por Rio-Hortega, Foot, Arteta e Jabonero.

    Urea and ethanol are the main precursors of ethyl carbamate (EC) in Chinese rice wine. During fermentation, urea is generated from arginine by arginase in Saccharomyces cerevisiae, and subsequently cleaved by urea amidolyase or directly transported out of the cell into the fermentation liquor, where it reacts with ethanol to form EC. To reduce the amount of EC in Chinese rice wine, we metabolically engineered two yeast strains, N85(DUR1,2) and N85(DUR1,2)-c, from the wild-type Chinese rice wine yeast strain N85. Both new strains were capable of constitutively expressing DUR1,2 (encodes urea amidolyase) and thus enhancing urea degradation. The use of N85(DUR1,2) and N85(DUR1,2)-c reduced the concentration of EC in Chinese rice wine fermented on a small-scale by 49.1% and 55.3%, respectively, relative to fermentation with the parental strain. All of the engineered strains showed good genetic stability and minimized the production of urea during fermentation, with no exogenous genes introduced during genetic manipulation, and were therefore suitable for commercialization to increase the safety of Chinese rice wine.

  18. The urease inhibitor NBPT negatively affects DUR3-mediated uptake and assimilation of urea in maize roots

    Full Text Available Despite the widespread use of urease inhibitors in agriculture, little information is available on their effect on nitrogen uptake and assimilation. Aim of this work was to study, at physiological and transcriptional level, the effects of NBPT on urea nutrition in hydroponically grown maize plants. Presence of NBPT in the nutrient solution limited the capacity of plants to utilize urea as a N-source; this was shown by a decrease in urea uptake rate and 15N accumulation. Noteworthy, these negative effects were evident only when plants were fed with urea, as NBPT did not alter 15N accumulation in nitrate-fed plants. NBPT also impaired the growth of Arabidopsis plants when urea was used as N-source, while having no effect on plants grown with nitrate or ammonium.This response was related, at least in part, to a direct effect of NBPT on the high affinity urea transport system. Impact of NBPT on urea uptake was further evaluated using lines of Arabidopsis overexpressing ZmDUR3 and dur3-knockout; results suggest that not only transport but also urea assimilation could be compromised by the inhibitor. This hypothesis was reinforced by an over-accumulation of urea and a decrease in ammonium concentration in NBPT-treated plants. Furthermore, transcriptional analyses showed that in maize roots NBPT treatment severely impaired the expression of genes involved in the cytosolic pathway of ureic-N assimilation and ammonium transport. NBPT also limited the expression of a gene coding for a transcription factor highly induced by urea and possibly playing a crucial role in the regulation of its acquisition.This work provides evidence that NBPT can heavily interfere with urea nutrition in maize plants, limiting influx as well as the following assimilation pathway.

Aim of this work was to study, at physiological and transcriptional level, the effects of N-(n-butyl) thiophosphoric triamide (NBPT) on urea nutrition in hydroponically grown maize plants. Presence of NBPT in the nutrient solution limited the capacity of plants to utilize urea as a N-source; this was shown by a decrease in urea uptake rate and (15)N accumulation. Noteworthy, these negative effects were evident only when plants were fed with urea, as NBPT did not alter (15)N accumulation in nitrate-fed plants. NBPT also impaired the growth of Arabidopsis plants when urea was used as N-source, while having no effect on plants grown with nitrate or ammonium.

  4. Tectonic history and structural development of the Zallah-Dur al Abd Sub-basin, western Sirt Basin, Libya

    Abdunaser, Khalifa M.; McCaffrey, Ken J. W.

    2015-04-01

    The Zallah-Dur al Abd Sub-basin area lies in the western part of the Sirt Basin of Libya. 2D seismic data covering an area of about 32,000 km² were studied along with the formation tops from 240 wells. We mapped a complex network of normal and probable strike-slip faults, generally striking NNW-SSE that control the asymmetry of the basin. Subordinate NE-SW structures acted as transverse faults controlling local depocentres that segment the Zallah-Dur al Abd Sub-basin. A number of active faults in the intra-basin area have been identified in seismic sections with generally moderate to high dip angles, and displaying evidence for positive and negative flower structures. The bordering extensional fault (the Gedari fault) passes at depth into a moderately SW-dipping structure crossing most of the Upper Mesozoic to Cenozoic stratigraphic section. Thickness variations adjacent to other major faults suggest also an original extensional system where inherited high-angle faults were reactivated throughout this time. A detailed analysis of the available seismic reflection and drill hole data shows that an obliquely rifted, multi-cyclic, NNW-SSE trending basin developed during the complex Upper Mesozoic Cenozoic rearrangement of Mediterranean tectonics. Multiple phases of rifting can be observed in the study area affecting a number of different horizons from Upper Cretaceous to Eocene. In the study area, the basin was initiated as a result of a Tethyan oblique extensional rift system that began in the Early Cretaceous and peaked in the Late Cretaceous. The basin reached its rift maturation phase during the Upper Cretaceous as a result of the continuing extensional tectonics on the marginal bounding NNW-SSE trending normal growth faults. During the Alpine-related tectonic pulses of Middle-Late Eocene the Sirt Basin underwent compression resulted in northward tilting of the basin, causing abrupt subsidence in the north and uplift on the basin southern shoulders, possibly

  5. Mediamania? Contemporary German Poetry in the Age of New Information Technologies: Thomas Kling and Durs Grünbein

    Directory of Open Access Journals (Sweden)

    Erk Grimm

    1997-01-01

    Full Text Available The essay examines the preoccupation with information technologies as a dominant theme of German poetry in the 1980s and 1990s. Outlining the historical shift from a critique of mass media to the ironic affirmation of hi-tech media, the investigation seeks an understanding of its driving forces. The analysis of Enzensberger's polemical essays on the culture industry shows the parallels and the difference in attitude between him and younger poets of the 1980s. A concise account of their publications illuminates the development of an aesthetically demanding poetry that kept aloof from the mass media. In their rejection of a common quotidian or sentimental tone, poets such as Thomas Kling and Durs Grunbein created new idioms and challenging forms while concentrating on hi-tech media as an epochal phenomenon. The sober reflection and technical terminology originate in a materialistic attitude, driven by the desire to regain the power of sophisticated aesthetic expression and to compensate for the loss of experience caused by the simulation of the past.The essay closes with a critical interpretation of the "mediamania" of the 1990s by giving heed to the fashionable remixing of poetic idioms that leaves the false impression of a new school of media poets.

  8. A Fish Assemblage from the Middle Eocene from Libya (Dur At-Talah) and the Earliest Record of Modern African Fish Genera.

    In the early nineteen sixties, Arambourg and Magnier found some freshwater fish (i.e., Polypterus sp., Siluriformes indet. and Lates sp.) mixed with marine members in an Eocene vertebrate assemblage at Gebel Coquin, in the southern Libyan Desert. This locality, aged ca 37-39Ma and now known under the name of Dur At-Talah, has been recently excavated. A new fish assemblage, mostly composed of teeth, was collected by the Mission Paléontologique Franco-Libyenne. In this paper, we describe freshwater fish members including a dipnoan (Protopterus sp.), and several actinopterygians: bichir (Polypterus sp.), aba fish (Gymnarchus sp.), several catfishes (Chrysichthys sp. and a mochokid indet.), several characiforms (including the tiger fish Hydrocynus sp., and one or two alestin-like fish), and perciforms (including the snake-head fish Parachanna sp. and at least one cichlid). Together with the fossiliferous outcrops at Birket Qarun in Egypt, the Libyan site at Dur At-Talah reduces a 10-Ma chronological gap in the fossil record of African freshwater fish. Their fish assemblages overlap in their composition and thus constitute a rather homogenous, original and significant amount of new elements regarding the Paleogene African ichthyofauna. This supports the establishment of the modern African freshwater fish fauna during this time period because these sites mostly contain the earliest members known in modern genera.

    Full Text Available Alonso Xuárez was no minor composer in the musical field of his time. The quality and effectiveness of his compositions makes them deserving of a leading place in Spanish and European music of the 17th century. In spite of this almost nothing is known about this composer prior to his being appointed to teach in the chapel of Cuenca cathedral. Virtually all the currently available data is of a secondary and collateral nature and arises from research into his disciple the organist Sebastián Durón, the renowned opera composer and teacher at the Capilla Real of Charles II.

    Alonso Xuárez no fue un compositor menor dentro del panorama musical de su tiempo. La calidad y eficacia de su música merece estar en primera línea de la música española y europea del siglo XVII. Sin embargo, el desconocimiento de este músico es casi completo con anterioridad a su nombramiento en el magisterio de capilla de la catedral de Cuenca. Prácticamente todos los datos expuestos hasta el momento han sido restos secundarios y colaterales desprendidos de otras investigaciones realizadas sobre la figura de su discípulo, el reputado compositor de teatro lírico y maestro de la Capilla Real de Carlos II, el organista Sebastián Durón.

    The processing of heavy {alpha}-contaminated equipment at the Marcoule Centre has been carried out for a long time by a rather expensive 'manual' method. It has become necessary to reduce these costs by using more automated methods. Two studies which have been carried out have shown that when the amount of waste to be treated is large and is composed mainly of plastic material, it is possible to design economic installations using cooling and shock demolition, conventional compaction leading to rather poor results. For average quantities, a cutting-up reservoir, used also for other purposes, makes it possible to solve these processing problems at Marcoule. The costs involved are much lower than those previously required in the case of so-called 'manual' methods. (author) [French] Le conditionnement du gros materiel contamine en {alpha} a longtemps ete effectue sur le Centre de Marcoule par une methode 'manuelle' assez couteuse. Il est apparu necessaire de chercher a reduire les couts en utilisant des methodes plus automatisees. Deux etudes ont permis de montrer que lorsque les quantites a traiter sont grandes et interessent surtout des dechets plastiques, on pouvait concevoir economiquement des installations utilisant le refroidissement et choc, le compactage classique donnant des resultats assez decevants. Pour les quantites moyennes, une piscine de decoupage, utilisable d'ailleurs a d'autres fins, permet de resoudre, a Marcoule, le probleme du conditionnement. Les frais sont tres inferieurs a ceux anciennement engages avec les methodes 'manuelles'. (auteur)

    The Dur At Talah escarpment (150 m thick and 150 km long) is exposed at the southern side of the Sirt Basin, central Libya. This outcrop exposes an Upper Eocene succession, composed by highly bioturbated fine grained sandstones to claystones at the base (New Idam Unit; 80-100 m thick), overlain by medium grained to microconglomeratic sandstones at the top (Sarir Unit; 60 m thick). The latter is split into two subunits of nearly equal thickness: the lower Sarir subunit, composed of medium to coarse cross-bedded sandstones; and the upper Sarir subunit, composed of very coarse to microconglomeratic sandstones. The whole succession evolves from shallow marine estuarine (the New Idam Unit) to fluvial deposits (the upper Sarir subunit). The sandstone of the lower Sarir subunit, which is the focus of this article, is previously misinterpreted as being deposited in a purely fluvial environment. However, close observations revealed that the depositional environment is largely tide-influenced. It is notably marked by conspicuous subaqueous dune cross-stratifications that bear a variety of discrete, multi-scale, sedimentary structures evidencing their deposition in tidal rather than fluvial setting. Mud drapes, tidal bundles, and perpendicularly draining and oppositely climbing ripples are largely developed. Among these structures, the most diagnostic are of millimetric to centimetric scale. As a prime aim of this article, all these sedimentary structures are described, interpreted, and discussed for the first time from this outcrop. Their style of association and the quality of their preservation provide an outstanding ancient example of tide-dominated siliciclastic systems. Such structures are rarely found together in one outcrop as they are in Dur At Talah, and they provide a significant indicators in identifying ancient bedforms of tidal origin. Evidences of subtidal and intertidal depositional environments are afforded by these structures. Criteria indicative of

    Full Text Available Oestrogenic effects of macerated aqueous extracts of the leaves of Holarrhena fl oribunda (G. Don Dur & Schinz on ovariectomized rat. Estrogenic effects of aqueous extracts of leaves of Holarrhena fl oribunda have been evaluated by uterotrophic assay. Ovariectomized mice were used and treated subcutaneously during seven days with 50, 100, 200 mg.kg-1 doses of Holarrhena fl oribunda and with 100, 200 mg.kg-1 doses of Holarrhena fl oribunda plus 25 mg.kg-1 of oestradiol 17-β. Estrogenic activity was analysed by uterine dry and wet weight, surrenal gland wet weight, vaginal opening, protein and cholesterol level in uteri horn. Administration of extracts to the doses of 100 and 200 mg.kg-1 exhibits increase of uterine dry and wet weight, surrenal gland wet weight, vaginal opening, protein levels and decrease of level of cholesterol in uterine horn. The results suggest that, aqueous extracts of Holarrhena fl oribunda possesses estrogenic type effect. But when 100 and 200 mg.kg-1 of Holarrhena fl oribunda were given alone with 25 mg.kg-1 of estradiol 17-β, the estrogenic effect was slight. These results supposed that H. fl oribunda is a weak phytoestrogen and the aqueous extracts of the leaves behad as partial agonistic

    2006-12-01

    Full Text Available A detailed chemical model describing the formation of soot and NO is applied to simulate emission formation in a heavy duty diesel engine. Cylinder flow and spray development is simulated using an engine CFD code - Speedstar. Combustion is described using a simple eddy break-up model. Modeling of the emission-chemistry/turbulent-flow interaction is based on a flamelet approach. Contrary to a typical flamelet concept, transport equations are solved for mass fractions of soot and NO. The reason being that these major emission constituencies are assumed to change slowly in comparison to typical time scales for chemical processes or transport processes important for combustion. Chemical reactions leading to production and destruction of soot and NO are, however, assumed to be fast. Soot and NO source terms are therefore evaluated from a flamelet library using a presumed probability density function and integrating over mixture fraction space. Results from simulations are compared to engine measurements inform of exhaust emission data and cylinder pressure. Un modèle avec chimie détaillée décrivant la formation des suies et du NO est appliqué à la simulation de la formation des polluants dans un gros moteur Diesel. L'écoulement et le spray sont modélisés avec le code de calcul Speedstar. La combustion est représentée par le modèle eddy break-up . La modélisation de l'interaction entre l'écoulement turbulent et la chimie des polluants est basée sur une approche de type flamelet . Cependant, à la différence d'autres travaux, des équations de transport pour les fractions massiques de suies et de NO sont résolues. Cela est justifié par la supposition que les temps caractéristiques de formation de ces composés sont longs comparés à ceux associés aux phénomènes de transport et aux réactions chimiques associées à la combustion. Cependant, les vitesses de réaction se rapportant aux suies et au NO sont supposées rapides. Cela

    We evaluated how the presence of sugar sources impacted the distribution of Aedes aegypti in different habitats in Durán, Ecuador. Land cover and normalized difference vegetation index maps were used to guide a random point sampling routine to select study grids (30 m × 30 m) in low vegetation (LV) and high vegetation (HV). Five individual plants, at one home in the LV and HV grid, were treated with a different colored, non-attractive, 60% sucrose solution to determine mosquito feeding and movement. Sugar alone is not attractive to mosquitoes, so spraying vegetation with a dyed sugar solution can be used for visual determination of sugar feeding. Outdoor collections using BG sentinel traps and indoor collections using aspirators were conducted at the treatment home and with collection points at 20, 40, and 60 m surrounding the treatment home for three consecutive days. A total of 3,245 mosquitoes in two genera, Aedes and Culex, was collected. The proportion of stained Ae. aegypti females was 56.8% (510/898) and 0% for males. For Culex, 63.9% (248/388) females and 36.1% (140/388) males were collected stained. Aedes aegypti and Culex spp. were found up to 60 m stained in both LV and HV grids. Significantly more stained females Ae. aegypti were found inside homes compared to females and males of Culex spp. in both habitats. This study identifies that outdoor sugar feeding is a common behavior of Ae. aegypti and can be targeted as a control strategy in urban habitats in Latin America.

    Full Text Available Este trabajo presenta un conjunto de consideraciones que surgen de una investigación en curso sobre producción artesanal indígena en la comunidad Chané de la localidad de Campo Durán, provincia de Salta, Argentina. En el contexto de las vulnerables condiciones socioeconómicas que atraviesan a este pueblo, las artesanías se presentan como una importante fuente de ingreso, al mismo tiempo que constituyen una de sus manifestaciones tradicionales más relevantes. Tras recorrer brevemente la historia de las artesanías Chané, se señalan las problemáticas fundamentales que se presentan en torno a esta actividad en la actualidad, focalizando en la dimensión económica. En este sentido, se propone que las artesanías Chané atraviesan un proceso de dinamización. El análisis realizado en este trabajo apunta a especificar este fenómeno y a comprender sus implicancias en la estructuración de los procesos productivos y la caracterización de los productores. Desde esta perspectiva, la dinámica actual de la producción artesanal Chané se vincula con dos cuestiones: el incremento de las posibilidades de comercialización y la necesidad de diversificar las fuentes de ingreso en un contexto de precarización del trabajo asalariado.This paper presents some considerations that emerge from current research on indigenous craft production in the Chané community of Campo Durán, province of Salta, Argentina.

After examining briefly the history of Chané handicrafts, some contemporary problems related to this activity are revealed, focusing on the economic dimension. In this sense, it is proposed that Chané crafts are undergoing a process of increased dynamism. The following analysis aims to explain this phenomenon and understand its

    MARÍA MÉLIDA DURÁN

    Una de las secciones especialmente nostálgicas pero a su vez más trascendentales es esta de Obituarios en la revista “Medicina”. Acostumbra ser uno de los nichos literarios de la prolífica y versátil pluma del Académico Efraím Otero o de la pulida pero algo menos abundante del también Académico Zoilo Cuéllar.

    Puede ser esta sección de igual manera la semilla biográfica para aquellos ilustres médicos colombianos que por esta Institución pasaron, que llamamos “necrológica”, para darle un toque menos fúnebre y más alegre, pues destaca lo mucho de positivo que tuvo la vida de quien se escribe.

    Nos duele hacerlo hoy sobre María Mélida Durán Merchán, a quien me costó trabajo dejar de decirle “de Rueda”, en referencia a su compañero de tantas luchas y padre de su hijo Marcelo, el urólogo de Marly, Manuel Rueda Salazar.

    Y repito que siento consternación al hacerlo pues su edad distaba mucho de la de aquel personaje a quien se refería el Académico Laurentino Muñoz al conversar con su amigo Germán Arciniegas, un par de intelectuales a quienes la senectud no quitó vitalidad alguna.

    Full Text Available The following discussion offers a panorama of the hermeneutical horizon from which the philological annotation apparatus of the Libro de los ritos critical edition was created. The book, written by the Dominican friar Diego Durán in 1579, describes the religious life of the Nahua people with emphasis in the Mexicas or Aztecs of the postclassical period. Also, this work offers some considerations about the ethnohistorical value of the Libro de los ritos and explains how this idea was used as a hypothesis to create the philological annotation apparatus of the critical edition. The value of the analysis of this experience is the contribution that it offers to the discussion between philologists about the proper methodology that must be used for the critical annotation of the Indian chronicles, documents that conserve the memory of the Native American people.

    Full Text Available O desenvolvimento do saco embrionário nas flores de Coffea Dewevrei é um processo mais demorado do que em C. canephora e muito mais lento do que em C. arabica. As primeiras divisões do megasporo funcional têm início no dia da abertura da flor, raros sacos embrionários se apresentando completos no 1.° dia; em geral estão completos aos oito dias e, independentemente da fertilização, apresentam os núcleos polares fundidos 10 dias após a abertura das flores. A fertilização se dá a partir do 6.° dia, sendo mais comum a partir do 10.° dia. É também a partir do 10.° dia que ocorrem as primeiras divisões do endosperma, que pode apresentar até 20 núcleos antes de se tornar celular, e isto pode ocorrer dos 22 aos 107 dias. Somente depois que o endosperma se apresenta celular é que se dá a l.ª divisão na célula-ôvo; e esta primeira divisão só foi observada aos 142 dias. Em óvulos dessa mesma idade foram observados pró-embriões em estado um pouco mais adiantado de desenvolvimento. O crescimento do endosperma em volume é lento na primeira fase; o óvulo, no entanto, cresce rapidamente em seguida à fertilização, atingindo em média, aos 142 dias, um tamanho 1500 vezes maior que seu tamanho por ocasião da abertura da flor. No mesmo espaço de tempo o endosperma torna-se, em média, somente 230 vezes o volume inicial. Mesmo na falta da fertilização o óvulo cresce ligeiramente durante os 30 primeiros dias; observam-se, porém, os sinais de degenerescência do saco embrionário, que não cresce. Em seguida, os tecidos do óvulo também degeneram e se isto ocorrer nos dois óvulos, o ovário se desprende da árvore; alguns chegam a se manter na planta até 107 dias.The embryo sac development in Coffea Dewevrei De Wild et Th.

    Full Text Available In his structural theory of history the French historian, Fernand Braudel breaks the tradition of the narrative historiography. He supports achronological thematic approaches and emphasizes the influence of anonymous forces instead of ‘prominent individuals’. He nuances the traditional history of events, the short time span which described impressive, but evanescent events. He analyses economic, social and mental structures (the slow-moving long time span, instead of focusing on public life in the narrow sense of the word. The French thinker, Paul Ricoeur interprets the history and the historicalness of the human being in terms of phenomenology and the existential philosophy. He does not reject the notion of the longue durée, but he redefines it. He criticizes Braudel for considering the geographical time instead of the lived time as the basis of the long time span. Ricoeur’s innovation is the following: he treats the long time span in close connection with the temporality of the world of the action. He stresses that events are not important in themselves; they become significant if they are integrated into a larger, teleological unity, and if they are able to transform certain structures for the long term. According to Ricoeur even Braudel could not break the narrativity of historiography as a historian. Braudel isunderstands himself: he does not reflect on the momentum that his most famous work, The Mediterranean and the Mediterranean World in the Age of Philip II, outlines a quasi-plot. As the closing passage of this plot Braudel describes an event, the death of the Spanish king which is the decisive factor in the collapse of a structure.

  19. Conception preliminaire de disques de turbine axiale pour moteurs d'aeronefs

    Science.gov (United States)

    Ouellet, Yannick

    The preliminary design phase of a turbine rotor has an important impact on the architecture of a new engine definition, as it sets the technical orientation right from start and provides a good estimate of product performance, weight and cost. In addition, the execution speed at this preliminary phase has become critical into capturing business opportunities. Improving upfront accuracy also alleviates downstream detailed design work and therefore reduces overall product development cycle time. This preliminary phase contains elements slowing down its process, including low interoperability of currently used systems, incompatibility of software and ineffective management of data. In order to overcome these barriers, we have developed the first module of a new Design and Analysis (D&A) platform for the rotor disc. This complete platform ensures integration of different tools processing in batch mode, and is driven from a single graphical user interface. The platform developed has been linked with different optimization methods (algorithms, configuration) in order to automate the disc design and propose best practices for rotor structural optimization. This methodology allowed reduction in design cycle time and improvement of performance. It was applied on two reference P&WC axial discs. The platform's architecture was also used in the development of reference charts to better understand disc performance within given design space. Four high pressure rotor discs of P&WC turbofan and turboprop engines were used to generate the technical charts and understand the effect of various parameters. The new tools supporting disc D&A, combined with the optimization process and reference charts, has proven to be profitable in terms of component performance and engineering effort inputs.

    Nelson, Alondra

    2016-10-01

    Black Lives Matter was first articulated just a few years ago, but it has been the leitmotif of antiracist struggles for generations. The Movement for Black Lives extends the work of previous movements that challenged forms of oppression that act on Black bodies with impunity. It should be understood in the context of Ida B. Wells' anti-lynching campaign, Fannie Lou Hamer's reproductive justice demands, and the Black Panther Party's health activism. The 50th anniversary of the Black Panther Party is an occasion to recall that its work confronted the callous neglect and the corporeal surveillance and abuse of poor Black communities. Similar demands have been the centrifugal force of social movements that for centuries have refused to have Black lives cast beyond the human boundary.

  2. Influence du débit de base et de la durée des éclusées sur la dérive d'alevins de truite commune : expérimentations en canal semi-naturel

    Directory of Open Access Journals (Sweden)

    LIEBIG H.

    1998-07-01

    Full Text Available Le fonctionnement par éclusées de certains ouvrages hydroélectriques installés sur des rivières de montagne à peuplement salmonicole est souvent considéré comme responsable du déficit en alevins observé sur les secteurs à l'aval immédiat du rejet. Une des causes majeures avancée de ce déficit est l'entraînement forcé des alevins dès l'émergence. Une approche expérimentale de ce phénomène est apparue nécessaire pour identifier et quantifier les facteurs mis en jeu. Un ancien bras de la rivière Oriège a été ainsi aménagé au niveau du canal de fuite de l'usine hydroélectrique d'Orlu, en Ariège (09. Ce système semi-naturel permet, sur un substrat et des abris naturels, de simuler des éclusées et de quantifier la dérive des alevins résultante. Sur un bief à faciès d'écoulement mixte radier-plat, nous avons testé deux modalités pour la durée des éclusées (10 minutes et 3 heures, associées à deux modalités pour la valeur du débit de base (débit précédant l'éclusée, soit 150 et 250 l/s. Le débit plafond des éclusées a été fixé à 1 500 l/s, ce qui correspond à un facteur de 6 à 10 par rapport aux débits de base, situation fréquemment rencontrée sur l'Oriège. Les résultats sont comparés et discutés. En définitive, il apparaît que les éclusées entraînent systématiquement une dérive forcée des alevins. Cette dérive intervient principalement au démarrage de l'éclusée et est d'autant plus forte que le débit de base est faible.

  4. Examples from the Greenland-Project - Gentle Remediation Optiones (GROs) on Pb/zn Contaminated Sites

    Science.gov (United States)

    Friesl-Hanl, Wolfgang; Kidd, Petra; Siebielec, Grzegorz

    2017-04-01

    The GREENLAND-project brought together "best practice" examples of several field applied gentle remediation techniques (EUFP7-project "Gentle remediation of trace element-contaminated land - GREENLAND; www.greenland-project.eu) with 17 partners from 11 countries. Gentle remediation options (GRO) comprise environmentally friendly technologies that have little or no negative impact on the soil. The main technologies are • phytoextraction • in situ immobilization and • assisted phytostabilization. Mining and processing activities affecting many sites worldwide negatively. The huge amounts of moved and treated materials have led to considerable flows of wastes and emissions. Alongside the many advantages of processed ores to our society, adverse effects in nature and risks for the environment and human health are observed. Three stages of impact of Pb/Zn-ore-treatment on the environment are discussed here: (1) On sites where the ores are mined impacts are the result of crushing, grinding, concentrating activities, and where additionally parts of the installations remain after abandoning the mine, as well as by the massive amounts of remaining deposits or wastes (mine tailings). (2) On sites where smelting and processing takes place, depending on the process (Welz, Doerschel) different waste materials are deposited. The Welz process waste generally contains less Cd and Pb than the Doerschel process waste which additionally shows higher water- extractable metals. (3) On sites close to the emitting source metal contamination can be found in areas for housing, gardening, and agricultural use. Emissions consist mainly from oxides and sulfides (Zn, Cd), sulfates (Zn, Pb, and Cd), chlorides (Pb) and carbonates (Cd). All these wastes and emissions pose potential risks of dispersion of pollutants into the food chain due to erosion (wind, water), leaching and the transfer into feeding stuff and food crops. In-situ treatments have the potential for improving the situation on site and will be shown by means of field experiments in Spain, Poland and Austria. Keywords: Mining and smelting, in-situ remediation, phytomanagement, gentle remediation options

    The effectiveness of pineapple juice in enzymatic browning inhibition was evaluated on the cut surface of banana slices. After storage of banana slices at 15 degrees C for 3 days, pineapple juice showed browning inhibition to a similar extent as 8 mM ascorbic acid but less than 4 mM sodium metabisulfite. Fractionation of pineapple juice by a solid-phase C18 cartridge revealed that the directly eluted fraction (DE fraction) inhibited banana polyphenol oxidase (PPO) about 100% when compared to the control. The DE fraction also showed more inhibitory effect than 8 mM ascorbic acid in enzymatic browning inhibition of banana puree during storage at 5 degrees C for 24 h. Further identification of the DE fraction by fractionation with ion exchange chromatography and confirmation using model systems indicated that malic acid and citric acid play an important role in the enzymatic browning inhibition of banana PPO.

    Full Text Available École de technologie supérieure, 1100, rue Notre-Dame Du fait de l’inhomogénéité densimétrique et structurale des vertèbres entre les individus et du fait que la résistance osseuse dépende de la densité osseuse et de la continuité du réseau trabéculaire, qui change avec l’âge, on ne peut pas considérer que le comportement en fatigue des vertèbres dépende uniquement de la contrainte appliquée. Dans cette étude, un modèle de prédiction de durée de vie est proposé permettant d’évaluer le nombre de cycles de fatigue avant dommage en fonction de la contrainte appliquée, de la densité osseuse et de l’âge du spécimen. Vu leur grande dispersion, les résultats des essais de fatigue publiés par Brinckmann (1988 ont été classifiés afin de pouvoir être analysés par la méthode des plans d’expériences. Un modèle non linéaire présentant un coefficient de détermination R2 de 94 % est établi. En comparant les valeurs prédites par ce modèle avec les résultats des essais de fatigue de Hansson (1987, on constate une certaine cohérence entre les résultats. Cette étude justifie l’hypothèse que la densité osseuse et l’âge outre la contrainte appliquée ont un effet sur la fatigue du rachis.Due to vertebral densimetric and structural inhomogeneity between individuals and the fact that bone strength varies with bone density and discontinuities within the trabecular lattice which changes with age, vertebral fatigue behavior cannot be considered as depending only on the cyclic stress.

E. gingivalis is considered pathogenic by some authors and commensal to others. It does not have a defined role in the installation of disease. To address some of this questions we studied a 100 patients who were seen through the Odontological Hospital from the Universidade Federal de Uberlândia in order to determine its frequency in the buccal cavity. The material were collected using swabs from four different buccal sites and the smears were stained by a modified Papanicolaou technique. The results revealed positivity index of 62%. The affinity of the dye to the food vacuole contents and to the ingested bactérias prevents clear visualisation of the central and peripherical chromatin constituents of the parasite's nucleus. Mouth washes with 3ml of saline from 10 patients, were used to evaluate which parasitological method of diagnosis (fresh, iron-haematoxylin stained, Giemsa and Papanicolaou gives better visualisation of the parasite. The mouth washes sediment from fresh material revealed 100% of positivity and clear visualisation of the free form and locomotion of the trophozoites. No stained technique of the smear showed adequate visualisation, presenting the nucleus partially covered by the food vacuoles.

    Miranda, Marisa A.

    2013-12-01

    Full Text Available This paper discusses Eugenics in Argentina, taking a long term view, exhuming historical continuities that survived over time while ignoring deep contextual changes. Thus, in reference to the history of science (of which the history of Eugenics forms a part we can identify longue duree as part of a transcendent cultural phenomenon. This persistence is motivated by the strength of its principles, enabling it to survive more or less unaffected by events occurring in the environment, which, from another perspective, would cause a reversal of the proposed thesis. This paradigmatic strength, which can also be understood as resistance, in biopolitical terms, has granted some immunity and that, in turn, has allowed Eugenics to produce its own antibodies even after the horrors of Nazism became known.Este trabajo analiza la eugenesia en Argentina desde un enfoque de larga duración, que, como tal, se mantuvo en el tiempo con cierta indiferencia a cambios contextuales profundos.

Esa fortaleza (o resistencia paradigmática es la que, leída en términos biopolíticos, le ha otorgado a la tardo eugenesia cierta inmunidad y que, a la vez, le ha permitido fabricar sus propios anticuerpos luego de conocidos los horrores del nazismo.

  16. Resilience of Past Landscapes: Resilience Theory, Society, and the Longue Durée

    Directory of Open Access Journals (Sweden)

    Charles L. Redman

    2003-07-01

    Full Text Available Resilience theory is an expanding body of ideas that attempts to provide explanations for the source and role of change in adaptive systems, particularly the kinds of change that are transforming. Scholars from various disciplines have contributed to the current state of this formulation. This article proposes that resilience theory would benefit from an increasing collaboration with archaeologists, who would provide a long-term perspective on adaptive cycles. Although archaeologists and anthropologists have written provocatively about studying the resilience of past and present societies, such an approach has not become common in these disciplines. We suggest, however, that a resilience framework offers a potential mechanism for reinvigorating the conceptual base of archaeological and anthropological disciplines. To make this case, we (1 highlight three features of resilience theory, including cross-scale interactions, information flow, and phases of the adaptive cycle; (2 examine the extent to which purely natural or social science analyses would give complementary or contradictory conclusions; and (3 discuss the implications of using a long-term integrative perspective for understanding linked social and ecological systems.

    Xerophyta humilis is a poikilochlorophyllous monocot resurrection plant used as a model to study vegetative desiccation tolerance. Dehydration imposes tension and ultimate loss of integrity of membranes in desiccation sensitive species. We investigated the predominant molecular species of glycerolipids present in root and leaf tissues, using multiple reaction monitoring mass spectrometry, then analysed changes therein during dehydration and subsequent rehydration of whole plants. The presence of fatty acids with long carbon chains and with odd numbers of carbons were detected and confirmed by gas chromatography. Dehydration of both leaves and roots resulted in an increase in species containing polyunsaturated fatty acids and a decrease in disaturated species. Upon rehydration, lipid saturation was reversed, with this being initiated immediately upon watering in roots but only 12 to 24 hr later in leaves. Relative levels of species with short-chained odd-numbered saturated fatty acids decreased during dehydration and increased during rehydration, while the reverse trend was observed for long-chained fatty acids. X. humilis has a unique lipid composition, this report being one of the few to demonstrate the presence of odd-numbered fatty acids in plant phosphoglycerolipids.

  1. Preference of a polyphagous mirid bug, Apolygus lucorum (Meyer-Dur for flowering host plants.

    Directory of Open Access Journals (Sweden)

    Hongsheng Pan

    Full Text Available Apolygus lucorum (Meyer-Dür (Hemiptera: Miridae is one of the most important herbivores in a broad range of cultivated plants, including cotton, cereals, vegetables, and fruit crops in China. In this manuscript, we report on a 6-year long study in which (adult A. lucorum abundance was recorded on 174 plant species from 39 families from early July to mid-September. Through the study period per year, the proportion of flowering plants exploited by adult A. lucorum was significantly greater than that of non-flowering plants. For a given plant species, A. lucorum adults reached peak abundance at the flowering stage, when the plant had the greatest attraction to the adults. More specifically, mean adult abundance on 26 species of major host plants and their relative standard attraction were 10.3-28.9 times and 9.3-19.5 times higher at flowering stage than during non-flowering periods, respectively. Among all the tested species, A. lucorum adults switched food plants according to the succession of flowering plant species. In early July, A. lucorum adults preferred some plant species in bloom, such as Vigna radiata, Gossypium hirsutum, Helianthus annuus and Chrysanthemum coronarium; since late July, adults dispersed into other flowering hosts (e.g. Ricinus communis, Impatiens balsamina, Humulus scandens, Ocimum basilicum, Agastache rugosus and Coriandrum sativum; in early September, they largely migrated to flowering Artemisia spp. (e.g. A. argyi, A. lavandulaefolia, A. annua and A. scoparia. Our findings underscore the important role of flowering plays in the population dynamics and inter-plant migration of this mirid bug. Also, our work helps understand evolutionary aspects of host plant use in polyphagous insects such as A. lucorum, and provides baseline information for the development of sustainable management strategies of this key agricultural pest.

  11. Study of fast electrons from hard-X radiation; Etude des electrons rapides a partir du rayonnement X-dur

    Energy Technology Data Exchange (ETDEWEB)

    Arslanbekov, R.

    1995-12-19

    The goal of this thesis is the study of fast electron dynamics by means of the hard X-ray diagnosis installed in TORE SUPRA and numerical simulations. Fast electrons are generated in the plasma in the presence of the injected lower hybrid (LH) waves. Two aspects are studied in detail: the lower hybrid wave propagation and absorption in a periodically perturbed media and 2-D Fokker-Planck modelling of the fast electron dynamics in the presence of the LH power. Ripple effects on lower hybrid wave propagation and absorption are investigated using the ray tracing technique. A cylindrical equilibrium is first studied and a strong modification of the ray dynamics is predicted. Calculations are carried out in a real toroidal geometry corresponding to TORE SUPRA. It is shown that the lack of toroidal axisymmetry of the magnetic field may result in a modification of the ray evolution even if the global ray evolution is governed by the larger poloidal inhomogeneity. Simulation of LH experiments are performed for TORE SUPRA tokamak which has a large magnetic ripple (7% at the plasma edge). By considering ripple perturbation in LH current drive simulations, a better agreement is found with experimental results, in particular with the hard-X spectra and the current density profiles. In the second part of the thesis, a 2-D modeling of the fast electron dynamics in the velocity phase space is considered, based on the 2-D relativistic electron Fokker-Planck equation. Electron distribution functions obtained are used to calculate non-thermal Bremsstrahlung emission for different TORE SUPRA shots in a wide range of experimental conditions.

    2009-01-01

    Full Text Available Abstract. Pogrammed cell death of peripheral blood mononuclear leucocytes from patients with acute inflammatory diseases (non-nosocomial pneumonia, acute appendicitis was investigated under ex vivo conditions, upon cultivation of the cells with selective inhibitors of JNK (SP600125 and р38 МАРК (ML3403. In vitro addition of SP600125 and ML3403 under oxidative stress conditions prevents increase of annexinpositive mononuclear cells numbers, thus suggesting JNK and р38 МАР-kinases to be involved into oxidative mechanisms of apoptosis deregulation. A role of JNK in IL-8 production by mononuclear leucocytes was revealed in cases of acute inflammation. Regulatory effect of JNK and p38 MAP-kinases can be mediated through activation of redox-sensitive apoptogenic signal transduction systems, as well as due to changes in cellular cytokine-producing function.

    Apolygus lucorum (Meyer-Dür) (Hemiptera: Miridae) is one of the most serious agricultural pests, feeding on a wide range of cultivated plants, including cotton, cereals and vegetables in the north of China. This insect can frequently switch between habitats and host plants over seasons and prefer plants in bloom. A. lucorum relies heavily on olfaction to locate its host plants finely discriminating different plant volatiles in the environment. Despite its economical importance, research on the olfactory system of this species has been so far very limited. In this study, we have identified and characterized an olfactory receptor which is sensitively tuned to (Z)-3-Hexenyl acetate and several flowering compounds. Besides being present in the bouquet of some flowers, these compounds are produced by plants that have suffered attacks and are supposed to act as chemical messengers between plants. This OR may play an important role in the selection of host plants.

    Oil separation from oil-water effluents containing secondary emulsions is very difficult by traditional techniques and requires using ultrafiltration through a membrane. Oil-water emulsions were ultra-filtered using a prototype of a rotating disk dynamic filtration system equipped with a 190 cm{sup 2} 50 kDa circular membrane. The turbidity of initial solution at 4%wt oil concentration (21 900 NTU) dropped to 2 NTU in the permeate after 15 min of filtration, representing an oil rejection coefficient of 99.5%. Permeate fluxes increased with disk rotation speed to reach 90 l.h{sup -1}.m{sup -2} at 2000 rpm and 24 deg. C. The addition of 6 mm vanes on the disk increased the permeate flux by 100% at the same speed. Micro emulsions were composed of 4 to 20% of cyclohexane, 0.5 to 16% of 2-butanol and 0.25 to 8% of dodecyl sodium sulphate (SDS) in pure water. Permeate fluxes, which were very high (200 l.h{sup -1}.m{sup -2}) at 2000 rpm with a smooth disk and the most dilute solution, dropped to 15 l.h{sup -1}.m{sup -2} for the most concentrated one. Addition of vanes permitted to increase these fluxes by 100%. (authors)

  19. Étude théorique et expérimentale du transfert du dioctyl phtalate à partir d'un disque de PVC plastifié plongé dans une huile comestible

    When polymer and liquid are contacted with each other, as in packaging, some mass exchanges may occur, which constitute a major drawback when the liquid is a foodstuff or blood. However, these mass transfers in the polymers can appear as very interesting from the industrial point of view, if one is able to use and control them. It is then necessary to have a good knowledge of these transfer processes which are controlled by diffusion. Dioctyl phthalate (DOP) migration into an edible oil was studied under worst conditions: high plasticization level (50% by weight) and temperature(30 circC). The quantitative analysis of DOP in a such complex liquid medium and in the PVC itself was made easy by the use of the radioactive tracer technique. A simplified mathematical model, obtained by neglecting the oil transport in the PVC, was evaluated. This model based on the research of a finite differences explicit solution allows to reproduce for the DOP, the concentration profiles in the polymer and the kinetics of transfer in the oil, with a P-value ≥ 0.001. La mise en contact polymère-liquide se traduit généralement par des échanges de matière entre les 2 milieux considérés, ce qui constitue un inconvénient majeur lorsque le liquide est un aliment ou le sang. Cependant, ces transferts de matière dans les polymères peuvent apparaître comme très intéressants sur le plan industriel, si l'on est capable de les utiliser et de les contrôler. Il est donc nécessaire d'avoir une bonne connaissance de ces processus de transfert qui sont contrôlés par diffusion. Nous avons étudié la migration du dioctyl phtalate (DOP) dans une huile comestible en nous plaçant dans les conditions les plus défavorables: taux de plastification (50% en poids) et température (30°C) élevés. L'analyse quantitative du DOP dans un milieu liquide aussi complexe et dans le PVC lui- même a été facilitée par l'utilisation de la technique des traceurs radioactifs. Un modèle mathématique simplifié en négligeant le transport de l'huile dans la masse de PVC a été testé. Ce modèle basé sur la recherche d'une solution aux différence finies explicite permet au seuil de 0,1% de reproduire pour le DOP, les profils de concentration dans le polymère et les cinétiques de transfert dans l'huile.

  1. French wholesale electricity and gas markets in 2007. Monitoring report; Le fonctionnement des marches de gros francais de l'electricite et du gaz naturel en 2007. Rapport de surveillance

    Energy Technology Data Exchange (ETDEWEB)

    2008-12-15

    Settled on 24 March 2000, the French Energy Regulatory Commission (CRE) is an independent authority. CRE supports an efficient functioning of the electricity and natural gas markets, to the advantage of final consumers. CRE ensures the absence of any discrimination, cross subsidy or obstacle to competition. CRE has examined the functioning of the wholesale markets for electricity and gas for the year 2007. The report discloses the results of a first set of analyses, as well as the next actions to be conducted in order to explain some observed behaviour. On the basis of analyses led on the electricity market, CRE observes that nuclear generation was marginal during 15% of the hours in 2007. Hydraulic generation was marginal during 25% of the hours, coal generation during 25% to 30% of the hours and oil generation during less than 2% of the hours in 2007. Finally, prices on the border markets were of high importance on the French prices which they determined during 20% to 25% of the hours of the year. On an efficient market, the price is driven by the marginal power plant among all those which contribute to satisfy the demand. Therefore the wholesale price formation is conditioned by the frequency of marginality of each generation sector and by the associated valuation of production. On the day-ahead market, when nuclear or hydraulic generation was marginal, the day-ahead price reflected the associated valuation which was decided by EDF. The level of this valuation was generally higher than the marginal generation cost of these plants. As a matter of fact, a producer, even market dominant, may legitimately seek to optimise its income, provided that there is no abuse of a dominant position or any price manipulation. Consequently, at this stage, the relevance of the valuation method for nuclear and hydraulic generation on the wholesale market is still to be checked. CRE has also demonstrated that generation transparency, even if it gradually increased, still needs to be improved at this stage. Published information on availability forecasts of power generation facilities were insufficient. Finally, CRE has established that the limited development of competition on the retail market and the implementation of the transitional regulated tariff for balancing markets (TaRTAM) have curbed the increase of the wholesale electricity market's activity. Considering these findings, CRE will carry out audits on the valuation methods used by EDF for its nuclear and hydraulic generation. Based on a public consultation, CRE will also formulate recommendations on generation transparency. On the gas wholesale market, CRE observes that the activity on the wholesale market has grown all along 2007 but remained focused on short-term trading. In particular, little public information was available on the market because most of the deals were concluded without intermediary. Moreover, CRE notes that the supplying conditions of suppliers who are not former incumbents in Europe were not satisfactory. These suppliers had to acquire most of their gas on the French market. In order to improve the transparency of the gas wholesale market, CRE will publish aggregated and anonymous information on the bilateral market according to information on volumes that will be collected from market participants.

    The diploid oat species containing the A genome of two types (Al and Ac) were studied by electrophoresis of grain storage proteins (avenins), chromosome C-banding, and in situ hybridization with probes pTa71 and pTa794. The karyotypes of the studied species displayed similar C-banding patterns but differed in size and morphology of several chromosomes, presumably, resulting from structural rearrangements that took place during the divergence of A genomes from a common ancestor. In situ hybridization demonstrated an identical location of the 45S and 5S rRNA gene loci in Avena canariensis and A. longiglumis similar to that in the A. strigosa genome. However, the 5S rDNA locus in A. longiglumis (5S rDNA1) was considerably decreased in the chromosome 3A1 long arm. The analysis demonstrated that these oat species were similar in the avenin component composition, although individual accessions differed in the electrophoretic mobilities of certain components. A considerable similarity of A. canariensis and A. longiglumis to the Avena diploid species carrying the As genome variant was demonstrated.

    Full Text Available La modélisation des systèmes physiques peut parfois être rendue difficile par la présence de bruits et perturbations. Lorsqu’il est possible de faire des hypothèses sur les caractéristiques de ces bruits et perturbations, les approches permettant d’inclure un modèle de ces perturbations dans le modèle du processus sont pertinentes et permettent entre autre de reconstruire l’état du processus. Cependant, ces hypothèses sont rarement satisfaites en pratique et, les modèles eux-mêmes sont parfois entachés d’erreurs. Néanmoins, ces grandeurs et paramètres non mesurés sont amenés à fluctuer entre des bornes relativement bien connues. C’est pourquoi il est naturel de se concentrer sur des estimateurs ensemblistes garantis en tout temps, dans un cadre déterministe à erreurs bornées. Ces méthodes relèvent de l’analyse par intervalles, qui est apparue pour la première fois dans l’ouvrage “Interval Analysis”, de R.E. Moore en 1966. Il a été montré que les modèles ensemblistes sont bien adaptés pour la détection d’aléas ou de défauts de processus et la formulation de diagnostics pertinents quant à l’amélioration du déroulement de processus. Après une présentation des modèles les plus courants, une analyse de l’endommagement des ouvrages d’assainissement de la ville de Rennes est entreprise. Ces ouvrages représentent le réseau unitaire et le réseau des eaux usées du système séparatif et sont constitués de matériaux à base cimentaire, armés ou non. L’endommagement est traduit par l’intermédiaire de différents indicateurs des propriétés des matériaux prélevés dans la ville. A ce jour, nous disposons d’une centaine de prélèvements effectués dans différentes rues et caractérisés par des dates de pose comprise entre 1892 à nos jours. Ainsi, dans ce travail, partant d’un modèle ensembliste du comportement des différents tronçons de canalisation des eaux usées, nous utilisons les techniques les plus récentes d’estimation ensembliste afin de diagnostiquer ces éléments. Une attention particulière est portée sur l’estimation du niveau de corrosion permettant d’envisager la programmation d’une réfection totale ou partielle. Building models of physical systems turns out to be an awkward task by the presence of noise and disturbance. It is not always possible to get information about disturbances and noises acting on the system. This may turn the usual stochastic framework inappropriate. In such cases, assuming bounded uncertainties may be a solution. An interesting way to go is then to use guaranteed estimation methods, which learn the state and/or parameters of the models from data. The set-membership models are well suited for fault detection and for making relevant diagnoses to improve the process evolution. A damage analysis of sewerage structures in Rennes (France is undertaken. These systems (unit network rainwater and wastewater or separate system consist of cement-based materials. The damage is quantified through various indicators of material properties (material extracted in the city. One hundred samples characterized by different streets and laying dates between 1892 and our days are analyzed. Thus, in this work, starting from a set-membership model of the behaviour of different sections of pipe wastewater, we use recent techniques of set-membership estimation to model and diagnose the system. A particular attention is paid to estimating the corrosion level for considering the full or partial rehabilitation.

    Heavy-ion collisions offer the unique possibility to create in the laboratory nuclear matter far from equilibrium. The electromagnetic probe constituted by hard photons and the Bose-Einstein correlations were used to study the properties of such a matter (size, density, temperature...). It is shown how the formalism has evolved from Young experiments to heavy-ion collisions experiments. The experiments performed with the photon multidetector TAPS at Ganil are described. The systems studied are: {sup 86}KR + {sup nat}Ni at 60.0 A.MeV, and {sup 181}Ta + {sup 197}Au at 39.5 A.MeV. Results are presented concerning the production of gamma, pi{sup 0}, e{sup +-} and {gamma}{gamma} correlation. The results are interpreted with the help of static and dynamic calculations describing hard photon production in heavy ion collisions. For the first time in Nuclear Physics, the existence of the Bose-Einstein effect for photons in the range of gamma is demonstrated, and the existence of two different photon sources is postulated, reflecting the density oscillations taking place in the nuclear matter created in heavy-ion collisions.

In isolation, this data allows for certain significant items of information to be collated concerning for example the occupation of the site, but this information is of a partial nature. Spatial analysis can only be based on the confrontation of different levels of data. Modelling data using the HBDS method (Hypergraph Based Data Structure emerges as an efficient method. The geographical deconstruction of the historical and archaeological data is first necessary. This preliminary stage allows not only to account for succeeding states but also to understand spatial dynamics.

  15. Unexpected Turns: The Aesthetic, the Pathetic and the Adversarial in the Long Durée of Art’s Histories

    Directory of Open Access Journals (Sweden)

    Griselda Pollock

    2012-12-01

    Full Text Available In a conference organized at the University of Birmingham in 2012, I was invited to reflect upon the current situation in Art History that is posited as being ‘After the New Art History’. What is this after-ness? Succession? Supersession? Replacement? Exhaustion? Erasure? Fashionability? Dare we ask what kind of ‘killing’ of the past or of Oedipal Feminist Mothers and Marxists Fathers is going on here? Or does this indicate simply that we need new directions in our discipline just to keep it alive? There is certainly a feeling around that we are in a period of transition. Former certainties about the tendencies within the discipline of art history have melted. Is this a sign of our condition as Liquid Modernity? There is a risk, however, of casting the recent past as being ‘over’, to be viewed nostalgically, or gratefully cast into the dustbin of has-been histories so that we can get back to business as normal or find new pastures exciting because they are different. Before I acquiesce to such a trend for newness per se, I want to reconsider what is being said to have come before and now is defined as being over. To do so, I shall argue for an understanding of the long-term nature of any one intervention seeking radically to change the ways we study art and the image, past and present. Equally, I suggest that such long-term projects are themselves subject to historical change, shifting in sensitive response to altered conditions and changed priorities, but also registering their own effects and opening new avenues of analysis. Finally this article performs a reading of the call for papers for the conference in order to tease out critical misrepresentations of the past that we are now supposed to come after. Displacing the model of old and new with notions of parallel trajectories and multiple settlements in the expanding, historically shifting but also deeply structured ‘landscape’ of the discipline, I propose as less phallic model of a field with many threads contributing to its complex engagements with art, with visuality, with subjectivity and with their forms of material and symbolic interaction.

    Full Text Available Effects of speed and the duration of grain filling and the accumulation of the assimilates of the stem in developing the durum wheat yield (Triticum durum Desf. in the culture conditions of the high plains of eastern Algeria. The present study was led on the experimental site of station ITGC in Setif. The objective is to determine the differences of duration and speed of filling and the contribution of the assimilates of the stems to the yield of 5 durum wheat genotypes (Triticum durum Desf.. The year effect is significant, what explains the fluctuation of the conditions of one growth year to another. The grain yield is associated to the great quantity of assimilates stored and transferred from the stems to the grain filling. The Mbb genotype which has an important stem height transfers more assimilates. The genotypes ADS497 and Deraa present large standard leaves. The beginning of the active phase of the grain filling corresponds to the beginning of the foliar senescence. Mbb presents a slower foliar drying rate, the speed of drying stationary recorded by ADS497 is of -0.5957 cm2 per day. The speed of grain filling is negatively related to the duration of filling. The participation of the assimilates coming from the stem decreases when the environment allows the expression of a better grain yield.

    Objective To study the job burnout of medical students during their internship period and observe their psycho-logical status. Methods 120 medical students of making the internship from June 2014 to April 2015 in a top three hospital were selected. Through SCL-90 and MBI-GS, the job burnout and psychological status of medical students was observed. Results The evaluation score of emotional exhaustion for medical interns was better than that of MBI-GS;the job burnout of medical students was easily caused by their cynicism and lower sense of achievement (P﹤0.05);the evaluation score of soma-tization for medical interns was not signficantly different from the general group (P﹥0.05); the evaluation scores of obses-sive-compulsive symptom, human relations, depression, anxiety, hostility, terror, paraphrenia, and mental disease for medi-cal students was signficantly higher than that of general group (P﹤0.05). Conclusion The medical interns generally have the job burnout. Their psycholigical status is poorer than that of the peers. It is necessary to enhance their psychological educa-tion, improve their mental health and set up the proper professional idea and value.%目的:研究医学生实习期间职业倦怠情况,观察其心理状况。方法选取120例2014年6月—2015年4月该校在某三甲医院实习的医学生为研究对象,采用症状自评量表(SCL-90)以及工作倦怠量表(MBI-GS)对医学生进行调查分析,观察医学实习生的职业倦怠现象以及心理状况。结果医学实习生情绪衰竭情况要优于马斯拉奇常模,而玩世不恭及成就感低落更容易引起医学实习生职业倦怠,P﹤0.05。医学实习生在躯体化方面与全国常模组对比差异无统计学意义,P﹥0.05;而在强迫症状、人际关系、抑郁、焦虑、敌对、恐怖、偏执以及精神病性方面得分则明显高于全国常模组,P﹤0.05。结论医学实习生普遍存在职业倦怠现象,而与同龄人相比心理状况也明显较差,应重视医学实习生心理教育,加强医学实习生的心理健康,树立正确的职业观、价值观。

    Full Text Available Les espèces du genre Paenibacillus secrètent une variété d’enzymes extracellulaires parmi lesquelles figurent plusieurs types de β glucanases. Nous avons réalisé un test de dégradation du xyloglucane sur 29 souches isolées par immunopiégeage et identifiées à P. polymyxa par le système API50CHB. Ces souches ont été groupées en séries qui correspondent aux échantillons de sols à partir desquels elles avaient été isolées. Des souches de références et des souches type E. coli ont été intégrées lors de cette étude pour comparer leur activité à celles des souches isolées des sols d’Algérie. Les résultats de cette recherche montrent que toutes les souches de P. polymyxa sont capables de dégrader le xyloglucane, alors que les souches des espèces testées n’ont pas cette activité. Ces résultats semblent suggérer que cette propriété est partagée par tous les P. polymyxa et qu’elle n’est pas liée au sol d’origine de nos souches ni à l’ancienneté de culture du blé de ces sols. Nous avons également montré que la xyloglucanase fait partie du pool d’enzymes inductibles qui ne sont normalement présentes qu’à l’état de traces dans les bactéries, et dont la synthèse est amplifiée considérablement en présence de leur substrat.

  3. Hard processes and fragmentation in a unified model for interactions at ultra-relativistic energies; Les processus durs et la fragmentation dans un modele unifie pour les interactions aux energies ultra-relativistes

    Drescher, H.J

    1999-06-11

    In this work we have developed hard processes and string fragmentation in the framework of interactions at relativistic energies. The hypothesis of the universality of high energy interactions means that many elements of heavy ion collisions can be studied and simulated in simpler nuclear reactions. In particular this hypothesis implies that the fragmentation observed in the reaction e{sup +}e{sup -} follows the same rules as in the collision of 2 lead ions. This work deals with 2 nuclear processes: the e{sup +}e{sup -} annihilation reaction and the deep inelastic diffusion. For the first process the string model has been developed to simulate fragmentation by adding an artificial breaking of string due to relativistic effects. A monte-Carlo method has been used to determine the points in a Minkowski space where this breaking occurs. For the second reaction, the theory of semi-hard pomerons is introduced in order to define elementary hadron-hadron interactions. The model of fragmentation proposed in this work can be applied to more complicated reactions such as proton-proton or ion-ion collisions.

  4. Expression of Xhdsi-1VOC, a novel member of the vicinal oxygen chelate (VOC) metalloenzyme superfamily, is up-regulated in leaves and roots during desiccation in the resurrection plant Xerophyta humilis (Bak) Dur and Schinz

    The annotation of novel plant genes is frequently based on sequence and structural similarity to known protein motifs. Understanding the biological function of these genes is dependent on identifying conditions under which they are activated, however. The resurrection plant, Xerophyta humilis is a good model system for identifying and characterizing genes which are important for desiccation tolerance. Desiccation induced-1 (dsi-1VOC), a previously uncharacterized plant gene, is up-regulated during desiccation in leaves, roots, and seeds in X. humilis. The X. humilis desiccation induced-1 gene, Xhdsi-1VOC, shares structural homology with the vicinal oxygen chelate (VOC) metalloenzyme superfamily. Proteins in this superfamily share little sequence similarity, but are characterized by a common βαβββ structural fold. A number of plant orthologues of XhDsi-1VOC have been identified, including Arabidopsis thaliana At1g07645, which is currently annotated as a glyoxalase I-like gene, and many ESTs derived from seed cDNA libraries. Xhdsi-1VOC and its orthologues do not, however, contain the glutathione and zinc binding sites conserved in glyoxalase I genes. Furthermore, expression of Xhdsi-1VOC in yeast failed to rescue a yeast glyoxalase I mutant. Messenger RNA transcripts for At1g07645 accumulate during seed maturation, but are not induced by water loss, salt or mannitol stress in vegetative tissue in Arabidopsis. It is concluded that dsi-1VOC is a seed-specific gene in desiccation-sensitive plants that is activated by water loss in vegetative tissues in the resurrection plant X. humilis and plays an important role in allowing plant tissues to survive loss of 95% of their relative water content.

    Full Text Available La Guerra de Sucesión constituye uno de los episodios que más han marcado la historia de Cataluña. Sin embargo, este interés aún no ha desvelado todos los interrogantes que suscita el giro dinástico de Cataluña en el año 1705. Entre los muchos puntos oscuros, es preciso avanzar en un mejor conocimiento de las causas que llevaron a los diferentes grupos de la sociedad catalana a su posición política. Así surgió la idea de un estudio monográfico sobre la familia Duran, la dinastía más importante de hombres de negocios de la Barcelona del siglo xviii, no sólo por su posición austracista en la guerra de Sucesión, lo que les acarreó la confiscación de bienes por la autoridad felipista, sino por la rápida integración de la nueva coyuntura generada por los Borbones. En efecto, el camalecnismo político de esta familia perteneciente a la burguesía mercantil, por otro lado nada excepcional, puede resultar ilustrativo para entender la posición de importantes sectores de la sociedad catalana durante la Guerra de Sucesión.The War of Succession is one of the events that most deeply marked the history of Catalonia. However, this interest has not yet revealed all the questions concerning the dinastic shift of Catalonia in 1705. Among other oscure aspects, it is necessary to reach a better knowledge about the reasons that led the different groups of Catalan society to their political position. In this context, the idea arouse to study the Duran familly, the most important dinasty of businessmen in eighteenthcentury Catalonia, not only by his Austracist position in the War of Succession —what brought them the confiscation of all their properties by Philip V's authorities—, but also by their quick integration in the new situation created by the Bourbon Monarchy. In fact, the chamaleon-like political behaviour of this merchant family —otherwise not unusual— can illustrate the political position of important groups of Catalan society during the War of Sucession.

    The objective is to qualify coatings without cobalt to replace ``Stellites`` coatings in isolation valves of PWR primary cooling system, as Co is activated when passing in the reactor core and contaminated the cooling loop. Three families of coatings were tested: PVD thin films from 1 to 8 {mu}m monolayers of Cr/C{sub x} with x varying between 1.6 and 9.5 at% or multilayers of pure chromium and Cr/C{sub 1.6} at%, coatings with a thickness between 100 and 200 {mu}m of cermets NiCr{sub y} (y varying from 5 to 35 at%) matrix binding chromium or tungsten carbides, and thick coatings 2 mm thickness of cermets Nitronic 60 or Inconel 625 matrix binding 10, 20 or 30% titanium or niobium carbides. Stellite 6 (2 mm) is the reference coating for tribology. Coatings were qualified and selected by thermal shocks, corrosion and plane friction. The thin film and the thick families were disqualified by their destruction or by their high friction coefficient. Then coatings between 100 and 200 {mu}m were used in a valve mock-up working in PWR primary cooling system pressure and temperature conditions. Tests show that these coatings have better wear or tightness performances than stellite 6, except for a slightly higher friction coefficient. (A.B.).

    1994-06-01

    Hard photons produced in heavy-ions collisions at intermediate energies have been used in order to study hot and compresses nuclear matter created in these collisions (at Ganil). It was found that Bremsstrahlung radiation emitted in np collisions is the main mechanism of hard-photon production for the whole range of impact parameter. Moreover, it was observed a substantial decrease of the hardness of hard-photon spectrum. The BUU model reproduces very well the experimental results, showing that the hardness of the spectrum reflects, mainly, nuclear-matter compression in the first stage of the collision. A new method was developed to measure the density of the nuclear matter created at the beginning of the collision. BUU results and some experimental evidences point out that a significant contribution of hard photons are produced in the last stage of the collision: thermal hard photons. These photons are sensitive to the density oscillation of nuclear matter. Its production cross-section will constitute a measurement of the compressibility of nuclear matter and its spectrum a measure of the temperature. (from author) 64 figs., 60 refs.

    X-ray diffraction experiments were carried out on large ice crystals from accreted ice above Lake Vostok, a subglacial lake lying beneath the East Antarctic ice sheet. Results indicate a surprisingly very low lattice distortion. This crystalline quality does not seem to be affected by impurities. Abnormal grain growth should occur and could explain both the large grain size and the low lattice distortion. Accreted ice is therefore supposed to be non-plastically deforming. These results should be taken into account for further studies of the permeability of accreted ice to drilling fluid present in the borehole.

    Full Text Available The steadiness over time, of on-board Energy Storage Systems (ESS performances is a major issue fora successful and massive diffusion of electrified, hybrid and electric vehicles. Capacity fade and internal resistance increase due to ageing will directly affect vehicle range and performances. Therefore, ESS ageing forecasting remains an important area of investigations. Reaching this goal involves fundamental research on materials, experimentation, simulation and design by the end users. This paper describes the main results of a 3.5-year, 4.2 M€ collaborative research program on battery ageing, SIMSTOCK, which was finished in fall 2011. This program has involved 15 partners among which, research labs, ESS manufacturers, automotive components suppliers and vehicle manufacturers, with the support of the French agency ADEME. This paper will then focus mainly on modeling and simulation of a lithium-ion high power cell tested within the program. First, it describes the development of a numerical equivalent electrical circuit model of battery, associated with a calibration tool and its experimental validation. Secondly, it describes the construction of a Design of Experiments (DOE, its use and validation, for defining mathematical expressions, representing the battery model parameters evolutions, as a function of battery ageing. Thirdly, the paper details a mathematical method created with the aim to take into account the cycling and the calendar effects on battery characteristics during the experiment on tests benches. Finally, the battery model is integrated in a full hybrid vehicle model, on Imagine Lab AMESim simulation platform, to determine, with realistic driving conditions, the impact of battery ageing on the vehicle performance and fuel consumption.

    The Scottish Registration Act of 1854 introduced compulsory civil registration of births, deaths and marriages under the GROS. The Royal College of Physicians of Edinburgh had long campaigned for such legislation, but was dissatisfied with certain sections of the Act. The College possessed strong views on how causes of death ought to be recorded, on the need for a medical Superintendent of Statistics to tabulate and analyse the causes of death for the GROS, on whether or not doctors should be fined for failing to provide certificates of cause of death, and on the importance of including meteorological data in the GROS's reports. Its Fellows accordingly strove to have the new registration measures tailored to their specifications. Drawing upon the College minutes, the GROS archives, and other contemporary sources, this article explains how the College succeeded in influencing some, but not all of these aspects of vital registration in Scotland.

    Les disques de poussières et de gaz autour des étoiles rejoignant la Séquence Principale sont les sites de formation des planètes extra-solaires dont l'existence s'est vu confirmée récemment. Cette thèse aborde l'étude de la poussière des environnements circumstellaires. Elle associe des observations spatiales à haute résolution angulaire, la modélisation des propriétés physico-chimiques des poussières et leur comportement optique, la modélisation des disques optiquement fins et la dynamique des planétésimaux à l'origine des grains observés autour des étoiles âgées. Les images obtenues avec le Télescope Spatial Hubble révèlent deux nouveaux disques circumstellaires autour des étoiles HD 141569 et HD 100546, parfois classées dans la catégorie des étoiles de Herbig. Bien que les systèmes présentent des âges proches (~10 millions d'années), les morphologies très différentes des disques mettent en évidence la difficulté pour élaborer un scénario unique d'évolution des systèmes protoplanétaires. L'anneau fin de poussières autour de HR 4796A, une étoile d'âge similaire aux précédentes, est marginalement résolu depuis le sol. La modélisation complète de ce disque permet de reproduire l'ensemble des observations disponibles. Ces résultats impliquent la présence de planétésimaux, à un âge aussi peu avancé, pour repeupler le disque en poussières poreuses et essentiellement amorphes qui sont soufflées par la pression de radiation. Une modélisation dynamique du prototypique disque autour de β Pictoris est proposée. Associée à une description réaliste du comportement optique des grains, cette approche reproduit les caractéristiques générales du disque ainsi que des asymétries plus fines en supposant la présence d'une planète dans un disque de planétésimaux et en tenant compte des effets différentiels de la pression de radiation sur les grains. Enfin, le modèle de disques que j'ai développé est exploit

    Objective To evaluate the effect of class 10000 laminar flow ward on the incidence of healthcare-asso-ciated infection (HAI)in patients with initial occurrence of acute leukemia during induction chemotherapy period. Methods Patients with initial occurrence of acute leukemia admitted to a hematological department of a hospital be-tween October 2013 and June 2014 were investigated retrospectively,patients in class 10000 laminar flow ward was as trial group,in general ward was as control group. All patients received standard induction chemotherapy and the same nursing measures,the incidence of HAI between two groups of patients,and ward air cleanliness were com-pared.Results A total of 79 patients with initial acute leukemia were received (trial group,n= 39;control group, n= 40). The average air cleanliness value in rooms and corridors of laminar flow wards were both significantly dif-ferent with general ward (3.57×106/m3 vs 149.36×106/m3 ,t= 45.80,P<0.001;24.46×106/m3 vs 15854.38 ×106/m3 ,t= 108.70,P<0.001). Incidence of HAI between trial group and control group was significantly differ-ent (23.08% [9/39]vs 45.00% [18/40],χ2= 4.219,P= 0.040). The main infection site in trial group was gastro-intestinal tract (n= 5 ),in control group was lower respiratory tract (n= 8 ). The duration of fever,duration and cost of antimicrobial use in trial group were (6.20±2.10)d,(9.35±2.12)d,and (27113.79±1559.03)yuan re-spectively,in control group were (10.20±2.90)d,(14.15±3.14)d,and (58566.29±2217.54)yuan respectively, difference in duration of fever and cost of antimicrobial use between two groups were all significant(t= 1.021, 1377.45,both P<0.05).Conclusion Laminar flow ward can reduce the incidence of HAI in patients with initial occurrence of acute leukemia,and decrease cost of antimicrobial use.%目的 探讨万级层流病房对初发急性白血病患者诱导化疗期间医院感染发病率的影响.方法 回顾性调查2013年10月—2014年6月某院血液科病房收治的初发急性白血病患者,万级层流病房收治的患者为试验组,普通病房收治的患者为对照组.所有患者均接受标准诱导化疗,接受相同的护理措施,比较两组患者医院感染发病率及病房空气洁净度.结果 共收治初发急性白血病患者79例,试验组39例,对照组40例.层流病房房间、走廊空气洁净度(分别为3.57×106/m3、24.46×106/m3)与普通病房(分别为149.36×106/m3、15854.38×106/m3)比较,差异均有统计学意义(t值分别为45.80、108.70,均P<0.001).医院感染发病率试验组为23.08%(9/39),对照组为45.00%(18/40),两组比较,差异有统计学意义(χ2=4.219,P=0.040).医院感染部位试验组主要为胃肠道(5例),对照组主要为下呼吸道(8例).患者发热持续时间、抗菌药物使用时间及费用,试验组分别为(6.20±2.10)d、(9.35±2.12)d、(27113.79±1559.03)元;对照组分别为(10.20±2.90)d,(14.15±3.14)d、(58566.29±2217.54)元;两组患者发热持续时间、抗菌药物使用费用比较,差异均有统计学意义(t值分别为1.021、1377.45,均P<0.05).结论 初发急性白血病患者使用层流病房,可降低其医院感染发病率,减少抗菌药物使用费用.

    Full Text Available Contribution to the study by PY/GC-MS of organic matter linked to fine particles (0-50 µm in some soils under long-term natural formations in Burkina Faso. The study aims to enhance the knowledge on organic matter of Arenosols, Ferralsols, and Cambisols in Burkina Faso. It deals with the distribution of C and N in three particles size fractions and is focused on the structures of organic matter linked to the (0-50 µm fraction. The results showed that total organic matter was lower than 2% in all soil units. More than 70% of total carbon were held by the finest fraction. The main products released by PY/GC-MS technique of the (0-50 µm fraction were lignin derived compounds, non lignin derived aromatic compounds, carbohydrates derived compounds, fatty acids methyl esters and nitrogen derived compounds. The aliphatic compounds ranged from C12 to C18, C16 being the dominant one. The aliphatic compounds were negatively correlated with the aromatic compounds. A positive correlation was observed between the nitrogen derived compounds and the amounts of clay. On the other hand, the carbohydrates derived compounds were negatively correlated with clay particles. Furthermore, the study pointed out some different structures of lignin such as syringyl, guaiacyl, and p.hydrophenyl. Depending on the nature of wood (hard wood, soft wood and grasses, they reflected the composition of vegetation on the studied sites. Therefore, PY/GC-MS technique was efficient for structural characterization of low amounts of soil organic matter.

    Introduction Le paludisme est une maladie parasitaire à transmission vectorielle qui constitue un problème majeur de santé publique dans les pays tropicaux, particulièrement les pays de l'Afrique Subsaharienne. La présente étude avait pour objectif d'identifier le niveau d'utilisation de la MILD chez les enfants de moins de 5 ans dans la zone de santé de Mumbunda. Méthodes L’étude, de type transversal, a été mené du 25 au 27 octobre 2013 et a porté sur un échantillon de 410 ménages tirés au hasard et ayant au moins un enfant de moins de 5 ans. Résultats Parmi les ménages qui avaient déclaré possédaient la MILD 13,1% (n=54) des répondant avaient déclaré les utilisé chez les enfants de moins de 5ans et 80,2% pour tout le monde. Dans 22,0% des cas, les répondants ont évoqué le manque d'argent comme motif de la non possession de la MILD. Les répondants savaient déclarer à 79,8% avoir utilisé la MILD pour se protéger contre la malaria et à 66,3% pour se protéger contre les piqures des moustiques. La MILD a été étalée à l'ombre pendant 24h avant d’être utilisée pour la première fois par 77,9% des ménages. Les répondants avaient déclaré à 15,3% (n=63) avoir reçu les conseils par les médias pour l'usage de la moustiquaire. Et le personnel médical était la source la plus importante pour expliquer le mode d'emploi de la MILD pour 51,2% des ménages. Conclusion La réussite pour faire reculer le paludisme doit nécessairement passer par la prévention, le suivi et l’évaluation de l'utilisation des moustiquaires imprégnées au niveau de la zone de santé de Mumbunda.

    Full Text Available Dominican Friar Diego Duran’s Historia de las Indias de Nueva España e Islas de la Tierra Firme (1581 is one of the most studied chronicles of missionary tradition, not only due to its thorough description of the aboriginal past and its illustrative prints, but fundamentally because of its complex mixture between criticism of idolatry, panegyric of evangelization and the hybridization present in the text. The speaking subject is presented as the agent of evangelization who discursively produces an approach to the aboriginal culture through his missionary and writing work.

  11. The Ethnic Hate Speech was Networked: What Social Media Online Political Discussions Reveal about the 2013 General Elections in Kenya / El discurso étnico del odio se difundió por las redes. Análisis de las discusiones políticas en las redes sociales dur

    Full Text Available This chapter examines if the increased political discussions on social media especially Twitter and Face Book before and after the March 4th, 2013 general elections in Kenya translated to a more robust Alternative Public Sphere that broke the hegemony of the traditional media as Agenda setters or an alternative space for the audience to vent out their frustrations and grievances about the election. In the last most contentious elections in 2007, in Kenya, both new and old media were blamed for fueling ethnic hate speech which culminated into the 2007/ 2008 post election violence. It is argued in this chapter that although voting patterns in the March 2013 elections were clearly along ethnic lines just like in 2007, there was no physical post election violence like was the case in 2008. What was clearly evident was Ethnic hate speech before and after the general elections on social media networks. We therefore observe that unlike in 2008 where ethnic violence was fought in the streets, in the 2013 general elections, the ‘Ethnic War was Networked’. The chapter analyses the content of some of the messages send on Twitter and Face Book to argue that social media platforms only acted as alternative spaces for Kenyans to fight out their ethnic political wars and not alternative public spheres for constructive political deliberation. The chapter concludes by observing that social media networks in the 2013 general elections in Kenya acted as ‘Opiums of the Masses’ only serving the function of keeping Kenya ‘quiet and peaceful’ to prevent a repeat of the 2008 post election violence, but not alternative public spheres to facilitate constructive political deliberation. En este artículo se analiza si el aumento de las discusiones políticas sobre las redes sociales, especialmente Twitter y Facebook, antes y después de las elecciones generales en Kenia del 04 de marzo de 2013, se tradujeron en una esfera pública alternativa sólida que rompiera con la hegemonía de los medios de comunicación tradicionales en tanto que fijadores de la agenda, o un espacio alternativo para la audiencia en el que tratar sus frustraciones y quejas sobre las elecciones. En las últimas elecciones más polémicas en Kenia, en 2007, tanto los nuevos medios como los tradicionales fueron acusados de alimentar la incitación al odio étnico, que culminó en la violencia sufrida a finales de 2007 y principios de 2008, después de las elecciones. El argumento de este texto señala que aunque los patrones de voto en las elecciones de marzo 2013 se delinearon claramente siguiendo un patrón étnico al igual que en 2007, no hubo violencia física postelectoral, como ocurrió en 2008. La incitación al odio étnico era ya evidente antes y después de las elecciones generales en las redes sociales. Por lo tanto, observamos que, a diferencia de 2008 donde la violencia étnica se libró en las calles, en las elecciones generales de 2013, esta violencia se canalizó a través de la red. El artículo utiliza el análisis de contenido cualitativo de algunos de los mensajes enviados a través de Twitter y Facebook para sostener que estas plataformas sólo sirvieron para los kenianos como espacios alternativos en los que escenificar su confrontación política étnica, y no como esferas públicas alternativas para la deliberación política constructiva. Por lo tanto, se concluye señalando que las redes sociales en las elecciones generales de 2013 en Kenia actuaron como "el opio del pueblo", que sólo sirvió para mantener Kenia tranquila y pacífica, con el fin de evitar que se repitiera la violencia post-electoral de 2008, pero no como esfera pública alternativa que facilitara la deliberación política constructiva.

The results showed that the annual mean pH value was less than 5.6 during 2004-2011. The proportion of acid rain cities annually had decreased since 2007, and the proportion of acid rain cities with acid rain occurrence frequency being over than 25% had decreased gradually since 2006. During 2004-2007,the distribution pattern of Guangxi acid rain region slightly changed. The area of acid rain region in Guangxi dramatically decreased. The rigid control of the SO2 emission recent years in Guangxi is play an important role in the decrease of pollution caused by acid rain.

    Le but de cette thèse est de décrire la formation des étoiles massives dans les galaxies spirales appartenant à divers types morphologiques. L'imagerie Hα profonde combinée à une robuste méthode d'identification des régions HII ont permis de détecter et de mesurer les propriétés (position, taille, luminosité, taux de formation d'étoiles) de plusieurs régions HII situées dans le disque interne (R influencer de façon significative la stabilité des nuages moléculaires face à l'effondrement gravitationnel. D'une part, l'étendue du disque de régions HII pour cinq galaxies de l'échantillon coïncide avec celle de l'hydrogène atomique. D'autre part, en analysant la stabilité des disques galactiques, on conclue qu'en incluant la densité des étoiles vieilles présentes, on arrive à mieux contraindre le rayon à partir duquel aucune formation d'étoiles ne devrait se produire dans les galaxies.

    Full Text Available L'exposé concerne l'activation des paraffines et des oléfines en présence d'hydrogène sur les métaux du groupe VIII. L'activation des paraffines fait intervenir les voies d'hydrogénolyse, d'isomérisation et de cyclisation. La profondeur d'hydrogénolyse permet de proposer un classement des métaux selon l'ordre croissant de la force de la liaison, paraffine chimisorbée-métal Pd-Pt-Ir-Rh-Ru-Os-Ni-Co-Fe L'activité spécifique d'hydrogénolyse, portée alors en fonction de la force de cette liaison, passe par un maximum autour de la position de Rh - Ru - Os. Les activités d'isomérisation et de cyclisation passent, par un maximum, pour la position de Pt. On retrouve ainsi la notion de force optimale de chimisorption pour catalyser une transformation précise. Sur la base des notions développées par Pearson, on peut alors considérer que la paraffine chimisorbée intervient plutôt en qualité de base «dure» de telle façon que la force de la liaison paraffine métal, augmente avec le caractère «dur» du métal. L'effet des ligands dans la sphère de coordination du site catalytique est ensuite analysé, en distinguant les ligands introduits lors de la préparation du catalyseur et ceux amenés par la phase réactionnelle.

    Full Text Available Abstract Background Drug utilization review (DUR programs are being conducted in Canadian hospitals with the aim of improving the appropriateness of prescriptions. However, there is little evidence of their effectiveness. The objective of this study was to assess the impact of both a retrospective and a concurrent DUR programs on the quality of in-hospital prescribing. Methods We conducted an interrupted time series quasi-experimental study. Using explicit criteria for quality of prescribing, the natural history of cisapride prescription was established retrospectively in three university-affiliated hospitals. A retrospective DUR was implemented in one of the hospitals, a concurrent DUR in another, whereas the third hospital served as a control. An archivist abstracted records of all patients who were prescribed cisapride during the observation period. The effect of DURs relative to the control hospital was determined by comparing estimated regression coefficients from the time series models and by testing the statistical significance using a 2-tailed Student's t test. Results The concurrent DUR program significantly improved the appropriateness of prescriptions for the indication for use whereas the retrospective DUR brought about no significant effect on the quality of prescribing. Conclusion Results suggest a retrospective DUR approach may not be sufficient to improve the quality of prescribing. However, a concurrent DUR strategy, with direct feedback to prescribers seems effective and should be tested in other settings with other drugs.

    Clopidogrel bisulfate (CBS) is antiplatelet drug and it is becoming a drug of choice in the treatment and management of prevention of heart attacks and strokes. CBS is stable and soluble in acidic pH; therefore, retention in stomach for prolonged period appears to be beneficial for controlling the bioavailability. The gastroretentive osmotic system (GROS) facilitates prolonged retention of drug in stomach and provides zero-order drug release. A complex formulation like GROS poses many challenges, and QbD tools can help in designing robust formulation which takes all aspects of product and process development in order to deliver a robust product. The GROS was formulated in three steps: core tablet, osmotic tablet, and gastroretentive osmotic tablet. The design of experiment was used for screening and optimization of formulation and process-related parameters. The dissolution study was carried out to analyze the release pattern of tablet. The optimized batch O-4 showed cumulative drug release of 19.43, 30.49, 64.41, and 85.11% at 2, 4, 8, and 12 h which is in the range of QTPP predictions. The novel technique of GROS was implemented successfully which demonstrates robust design giving consistent and desired results.

    approche, dite de tomographie variationnelle, propose de reconstruire l'etat en restreignant l'espace de recherche a une classe variationnelle plutot qu'a l'immense espace des etats possibles. Un etat variationnel etant decrit par un petit nombre de parametres, un petit nombre d'experiences peut suffire a identifier les parametres variationnels de l'etat experimental. Nous montrons que c'est le cas pour deux classes variationnelles tres utilisees, les etats a produits matriciels (MPS) et l'ansatz pour intrication multi-echelle (MERA). Memoires quantiques auto-correctrices 2D. Une memoire quantique auto-correctrice est un systeme physique preservant de l'information quantique durant une duree de temps macroscopique. Il serait done l'equivalent quantique d'un disque dur ou d'une memoire flash equipant les ordinateurs actuels. Disposer d'un tel dispositif serait d'un grand interet pour l'informatique quantique. Une memoire quantique auto-correctrice est initialisee en preparant un etat fondamental, c'est-a-dire un etat stationnaire de plus basse energie. Afin de stocker de l'information quantique, il faut plusieurs etats fondamentaux distincts, chacun correspondant a une valeur differente de la memoire. Plus precisement, l'espace fondamental doit etre degenere. Dans cette these, on s'interesse a des systemes de particules disposees sur un reseau bidimensionnel (2D), telles les pieces sur un echiquier, qui sont plus faciles a realiser que les systemes 3D. Nous identifions deux criteres pour l'auto-correction: - La memoire quantique doit etre stable face aux perturbations provenant de l'environnement, par exemple l'application d'un champ magnetique externe. Ceci nous amene a considerer les systemes topologiques 2D dont les degres de liberte sont intrinsequement robustes aux perturbations locales de l'environnement. - La memoire quantique doit etre robuste face a un environnement thermique. Il faut s'assurer que les excitations thermiques n'amenent pas deux etats fondamentaux

  1. Estimating the mean and standard deviation of environmental data with below detection limit observations: Considering highly skewed data and model misspecification.

    Science.gov (United States)

    Shoari, Niloofar; Dubé, Jean-Sébastien; Chenouri, Shoja'eddin

    2015-11-01

    In environmental studies, concentration measurements frequently fall below detection limits of measuring instruments, resulting in left-censored data. Some studies employ parametric methods such as the maximum likelihood estimator (MLE), robust regression on order statistic (rROS), and gamma regression on order statistic (GROS), while others suggest a non-parametric approach, the Kaplan-Meier method (KM). Using examples of real data from a soil characterization study in Montreal, we highlight the need for additional investigations that aim at unifying the existing literature. A number of studies have examined this issue; however, those considering data skewness and model misspecification are rare. These aspects are investigated in this paper through simulations. Among other findings, results show that for low skewed data, the performance of different statistical methods is comparable, regardless of the censoring percentage and sample size. For highly skewed data, the performance of the MLE method under lognormal and Weibull distributions is questionable; particularly, when the sample size is small or censoring percentage is high. In such conditions, MLE under gamma distribution, rROS, GROS, and KM are less sensitive to skewness. Related to model misspecification, MLE based on lognormal and Weibull distributions provides poor estimates when the true distribution of data is misspecified. However, the methods of rROS, GROS, and MLE under gamma distribution are generally robust to model misspecifications regardless of skewness, sample size, and censoring percentage. Since the characteristics of environmental data (e.g., type of distribution and skewness) are unknown a priori, we suggest using MLE based on gamma distribution, rROS and GROS.

    2015-12-01

    Construction of dams and the resulting water impoundments are one of the most common engineering procedures implemented on river systems. One major problem in dams' impact studies is the lack of reliable methods for simulating reservoir operation. We have used Artificial Neural Networks (ANN) to parameterize actual dam operations and developed a General Reservoir Operation Scheme (GROS) which may be added to daily hydrologic routing models for simulating the releases from dams in regional and global-scale studies. GROS is sufficiently accurate in simulating the operation of existing reservoirs and is specifically designed to provide a broad perspective of the general behavior of dams and improve the understanding of the large-scale hydrological impact of dams operation in a relatively easy and efficient way. Embedding GROS in a water balance model (WBMplus), we are analyzing the hydrological impact of dams on the thirteen states of the Northeastern United States. Our analysis shows the changing trends in hydrological characteristics of each state for the period of 1950 to 2099 under the four Representative Concentration Pathways (RCPs). We demonstrate how the magnitude and timing of minimum and maximum monthly flows change as a result of climate change and explore the role of reservoirs in that change. In addition, we investigate whether building new dams can provide engineered resilience to climate change and enhance future water security.

    Although even randomization (that is, approximately 1:1 randomization ratio in study arms) provides the greatest statistical power, designed uneven randomization (DUR), (for example, 1:2 or 1:3) is used to increase participation rates. Until now, no convincing data exists addressing the impact of DUR on participation rates in trials. The objective of this study is to evaluate the epidemiology and to explore factors associated with DUR. We will search for reports of RCTs published within two years in 25 general medical journals with the highest impact factor according to the Journal Citation Report (JCR)-2010. Teams of two reviewers will determine eligibility and extract relevant information from eligible RCTs in duplicate and using standardized forms. We will report the prevalence of DUR trials, the reported reasons for using DUR, and perform a linear regression analysis to estimate the association between the randomization ratio and the associated factors, including participation rate, type of informed consent, clinical area, and so on. A clearer understanding of RCTs with DUR and its association with factors in trials, for example, participation rate, can optimize trial design and may have important implications for both researchers and users of the medical literature.

  14. Trans-Amazonian U-Th-Pb monazite ages and P-T-d exhumation paths of garnet-bearing leucogranite and migmatitic country rock of the southeastern Tandilia belt, Rio de la Plata craton in Argentina

    2017-03-01

    A garnet-bearing leucogranite and two country rocks from the Transamazonian Tandilia belt of the Rio de la Plata craton were studied in detail. The leucogranite contains garnet with homogeneous composition of pyr6(gros + andr)2spes5alm87. In a garnet-biotite migmatite, the core and rim compositions of garnet are pyr1.7(gros + andr)5spes5.6alm87.7 and pyr1.2(gros + andr)5.5spes6.7alm86.6, respectively. These compositions in a sillimanite-garnet-muscovite migmatite are pyr4(gros + andr)2.7spes2.7alm90.6 and pyr2.7(gros + andr)4spes3.2alm90.1, respectively. We used this information to decipher the P-T evolution of the rocks applying P-T and T-H2O pseudosections with the PERPLE_X computer software package taking into consideration deformational microstructures. The leucogranite records an isothermal decompression from 5.3 to 3.8 kbar at 665 °C. The garnet-biotite migmatite was exhumed from 5.5 kbar at 630 °C to 4.3 kbar at 615 °C and the sillimanite-garnet-muscovite migmatite from supersolidus conditions of 670 °C and 3.6 kbar to 625 °C at 2.4 kbar. Late andalusite formed in this rock. Seventy four analyses of 28 monazite grains of the country rocks yielded three groups of U-Th-Pb ages which were related to a collisional event (I: ca. 2.13-2.14 Ga.), a postcollisional thermal overprint (II: ca. 2.01 Ga) and slow cooling of the orogen (III: 1.80-1.90 Ga). Inherited ages of 2.28 and 2.25 Ga could refer to an early accretionary stage of the orogen. An age of 2.41 Ga indicates the presence of recycled Siderian continental crust. Synkinematic crystallization of melts and the subsolidus development of an S2-foliation, demonstrated by deformational microstructures, occurred during the exhumation of the studied area from depths of 18 km to 8 km in the time interval 2.01-1.90 Ga.

  17. Agp2, a Member of the Yeast Amino Acid Permease Family, Positively Regulates Polyamine Transport at the Transcriptional Level

    2013-06-03

    Agp2 is a plasma membrane protein of the Saccharomyces cerevisiae amino acid transporter family, involved in high-affinity uptake of various substrates including L-carnitine and polyamines. The discovery of two high affinity polyamine permeases, Dur3 and Sam3, prompted us to investigate whether Agp2 directly transports polyamines or acts instead as a regulator. Herein, we show that neither dur3? nor sam3? single mutant is defective in polyamine transport, while the dur3? sam3? double mutant exhibits a sharp decrease in polyamine uptake and an increased resistance to polyamine toxicity similar to the agp2? mutant. Studies of Agp2 localization indicate that in the double mutant dur3? sam3?, Agp2-GFP remains plasma membrane-localized, even though transport of polyamines is strongly reduced. We further demonstrate that Agp2 controls the expression of several transporter genes including DUR3 and SAM3, the carnitine transporter HNM1 and several hexose, nucleoside and vitamin permease genes, in addition to SKY1 encoding a SR kinase that positively regulates low-affinity polyamine uptake. Furthermore, gene expression analysis clearly suggests that Agp2 is a strong positive regulator of additional biological processes. Collectively, our data suggest that Agp2 might respond to environmental cues and thus regulate the expression of several genes including those involved in polyamine transport. © 2013 Aouida et al.

    DepoDur, an extended-release epidural morphine, has been used effectively for postoperative pain control following many orthopaedic and general surgery procedures and has provided prolonged analgesia when compared with Duramorph. The goal of this article was to compare the safety and analgesic efficacy of DepoDur versus Duramorph after lumbar spine surgery. A prospective, randomized, double-blind clinical study was completed at a single extended-stay ambulatory surgery center. All patients over 18 undergoing posterior lumbar spine fusions were considered for the study. Sixty patients were randomly assigned to a control or treatment group. The control group received DepoDur before surgery, while the treatment group received Duramorph. Although results show no significant differences between the two groups in postoperative visual analog pain scale scores, use of pain medication, and adverse events, subjects receiving DepoDur were less likely to receive Naloxone and oxygen supplementation, experience nausea or fever, and were more likely to experience hypotension. DepoDur proved to be safe and effective, offering similar prolonged analgesic activity when compared with Duramorph.

    Full Text Available Background & objectives: Information available on drug consumption is inadequate in most low and middle income countries. This systematic review was conducted to analyse published work on drug utilization research/studies (DUR in the SEARO region of WHO for study objectives, methodology, results and recommendations and to identify the need for improving DUR and the use of the ATC/DDD system. Methods: A literature search for DUR was carried out in biomedical databases (PubMed, Scirus, Scopus and Google Scholar up to May 2012. Publications were selected if those were in the English language, describing DUR or prescription practices, and study conducted in the WHO-SEARO countries. Results: A total of 318 publications were included in the review. Of these, 67 per cent were from India and 13 per cent were from Thailand. Majority of the publications were hospital based; only 16 per cent were community based. The ATC/DDD system was used in only 20 per cent of the publications, of which 73 per cent publications used DDD indicators. Several publications focused on antibiotics (31%. Publications that recommended the need for a policy or intervention to improve prescription practices/rational drug use amounted to 35 per cent. Interpretation & conclusions: Drug utilization studies using ATC/DDD system need to be promoted and carried out on an ongoing basis. DUR is important for rational use of drugs. Its relevance to policy making and resource allocation needs to be emphasized.

  20. A semi-quantitative method to denote generic physical activity phenotypes from long-term accelerometer data--the ATLAS index.

    Directory of Open Access Journals (Sweden)

    Michael Marschollek

    Full Text Available BACKGROUND: Physical activity is inversely correlated to morbidity and mortality risk. Large cohort studies use wearable accelerometer devices to measure physical activity objectively, providing data potentially relevant to identify different activity patterns and to correlate these to health-related outcome measures. A method to compute relevant characteristics of such data not only with regard to duration and intensity, but also to regularity of activity events, is necessary. The aims of this paper are to propose a new method--the ATLAS index (Activity Types from Long-term Accelerometric Sensor data--to derive generic measures for distinguishing different characteristic activity phenotypes from accelerometer data, to propose a comprehensive graphical representation, and to conduct a proof-of-concept with long-term measurements from different devices and cohorts. METHODS: The ATLAS index consists of the three dimensions regularity (reg, duration (dur and intensity (int of relevant activity events identified in long-term accelerometer data. It can be regarded as a 3D vector and represented in a 3D cube graph. 12 exemplary data sets of three different cohort studies with 99,467 minutes of data were chosen for concept validation. RESULTS: Five archetypical activity types are proposed along with their dimensional characteristics (insufficiently active: low reg, int and dur; busy bee: low dur and int, high reg; cardio-active: medium reg, int and dur, endurance athlete: high reg, int and dur; and weekend warrior: high int and dur, low reg. The data sets are displayed in one common graph, indicating characteristic differences in activity patterns. CONCLUSION: The ATLAS index incorporates the relevant regularity dimension apart from the widely-used measures of duration and intensity. Along with the 3D representation, it allows to compare different activity types in cohort study populations, both visually and computationally using vector distance

  1. Factors that influence the membrane area of a multistage microfiltration process required to produce a micellar casein concentrate.

    Hurt, Emily E; Barbano, David M

    2015-04-01

    The objective of the work reported in this paper was to develop a theoretical model to determine the effect of type of microfiltration (MF)-process feed, number of stages, and flux on the minimization of the MF membrane area required to produce a 95% serum protein-reduced micellar casein concentrate. The MF feed, number of stages, and flux were all factors that had an effect on the MF membrane area and should be taken into consideration when designing a MF system to produce a 95% serum protein-reduced micellar casein concentrate. Feeding the MF process with a diluted ultrafiltration retentate (DUR) diluted to the protein concentration of skim milk, as opposed to skim milk, reduced the required membrane area by 36% for a 5-stage process. When DUR was the MF feed, feed protein concentration, which depended on the number of MF stages, was optimized. The DUR protein concentration that minimized the required MF membrane area was 2.47, 3.85, 4.77, and 5.41% for a 2-, 3-, 4-, or 5-stage MF process, respectively. For a 5-stage process, increasing the protein concentration of the feed from 3.2 to 5.4% decreased the required MF membrane area by 10%. It was also found that as the number of stages increased from 2 to 5, the required MF membrane area decreased by 39%, when the MF feed was DUR at the optimal feed protein concentration. Finally, increasing the flux from 50 to 60 kg/m(2) per hour decreased the required MF membrane area by 17% when the MF feed was DUR at the optimal MF feed protein concentration. Overall, using DUR as a feed for MF could reduce the amount of MF membrane area required to make a 95% serum protein-reduced micellar casein concentrate.

Cette condition est donc contradictoire à la fois avec une production de spermatozoïdes précoce, qui nécessite des jours croissants, et avec le mainti...

  3. Conte nt of nutritive components, dietary fi bre and energy value of artichoke depending on the variety

    Full Text Available Background. The artichoke (Cynara scolymus L. is a perennial plant belonging to Asteraceae family. It is less popular vegetable in Poland but very valuable from nutritive and medicinal points of view plant. Material and methods. The experiments were conducted in 2008 and 2009 on fi ve artichoke varieties: ‘Deutscher Hybrid’, ‘Emerald F1’, Green Globe’, ‘Gros Camus de Bretague’ and ‘Kerlouan’, grew in Poland, France and Austria. The experimental material was assessed for: dry mass, protein, ash, vitamin C and dietary fi ber contents and some mineral components (calcium, magnesium, phosphorus, potassium, sodium, iron, zinc levels. Also the energy value and total carbohydrates content were calculated in the vegetable. Results. Among assessed varieties, the highest contents of such components as: dry mass (total solids, carbohydrates, ash, vitamin C, sodium, potassium, magnesium, iron were found in ‘Gros Camus de Bretague’. The hearts of that artichoke had also higher energy value than others. Whereas the lowest ash, phosphorus, sodium, potassium and magnesium were noticed in ‘Kerlouan’ variety. But the highest values of dietary fi ber was observed in that variety. Conclusions. Basing on performed assessments the differences in nutritive components and dietary fi ber, between analysed vegetable varieties were found.

  4. Members of Gammaproteobacteria as indicator species of healthy banana plants on Fusarium wilt-infested fields in Central America

    Köberl, Martina; Dita, Miguel; Martinuz, Alfonso; Staver, Charles; Berg, Gabriele

    2017-01-01

    Culminating in the 1950’s, bananas, the world’s most extensive perennial monoculture, suffered one of the most devastating disease epidemics in history. In Latin America and the Caribbean, Fusarium wilt (FW) caused by the soil-borne fungus Fusarium oxysporum f. sp. cubense (FOC), forced the abandonment of the Gros Michel-based export banana industry. Comparative microbiome analyses performed between healthy and diseased Gros Michel plants on FW-infested farms in Nicaragua and Costa Rica revealed significant shifts in the gammaproteobacterial microbiome. Although we found substantial differences in the banana microbiome between both countries and a higher impact of FOC on farms in Costa Rica than in Nicaragua, the composition especially in the endophytic microhabitats was similar and the general microbiome response to FW followed similar rules. Gammaproteobacterial diversity and community members were identified as potential health indicators. Healthy plants revealed an increase in potentially plant-beneficial Pseudomonas and Stenotrophomonas, while diseased plants showed a preferential occurrence of Enterobacteriaceae known for their plant-degrading capacity. Significantly higher microbial rhizosphere diversity found in healthy plants could be indicative of pathogen suppression events preventing or minimizing disease expression. This first study examining banana microbiome shifts caused by FW under natural field conditions opens new perspectives for its biological control. PMID:28345666

    Full Text Available En este trabajo pongo en consideración si corresponde o no afirmar que el psicoanálisis nació como empresa de medicalización del cuerpo sexual y por ello participa de una filiación disciplinaria. Para esto tomo en cuenta algunas reflexiones de Frédéric Gros acerca del concepto de sexualidad en la obra de Foucault, ciertos pasajes de Historia de la locura en la época clásica, El poder psiquiátrico y Entre filosofía y literatura, para confrontarlos con otras consideraciones que hiciera J. Derrida sobre el lugar y el rol del psicoanálisis en el proyecto foucaultiano de una historia de la locura. In this work I consider the question whether corresponds to affirm that Psychoanalysis was born as an enterprise with the purpose of medicalising the sexual body, and thus it is part of a discipline. For this analysis I take into account some of the thoughts by Frédéric Gros about the concept of sexuality in the work of Foucault, some fragments of History of Madness, Psychiatric Power and Dits et écrits, to confront them with other considerations by J. Derrida about the place and role of the Psychoanalysis on Foucault´s project for a history of madness.

  6. Integration of Gas Nitrocarburising and Oxidising in a Mass Production Line for Brake Pistons

    The combination of wear- and corrosion resistance is a demand to a multitude of automotive parts. Several metallic coatings as hard/soft chromium or electroless nickel have been the conventional surface protection e.g. on parts as brake pistons and shock absorber or gas spring piston rods. The Corr-I-Dur(R) process - a special gasnitrocarburising and oxidising technology - has a huge potential not only in substituting those coatings but also in delivering surfaces with higher quality.The benefits of the replacement of soft chromium with Corr-I-Dur(R) and the implementation of the process in the customers production line with an annual capacity of 17 million brake pistons is described in this presentation. Starting with the demands on wear- and corrosion resistance the way of process development and the design of applicative equipment is shown. The result is a tailor-made surface solution with superior quality for deep drawn brake pistons. Two main disadvantagesoutgassing of the chromium layer and reduced corrosion resistance on the inner diameter - are eliminated by the replacement with Corr-I-Dur(R). The process-sure achievement of enhanced corrosion resistance, uniform layer thickness, negligible distortion as well as environmental and economical advantages make Corr-I-Dur(R) an excellence choice for this application.

    Several `great walls' are clearly visible in the Durham/UKST Galaxy Redshift Survey (DURS). We make a statistical study of this superlarge-scale structure (SLSS) by applying our core sampling, cluster, inertia tensor and minimal-spanning-tree analyses to the DURS. The results in the main support similar results from the complementary Las Campañas Redshift Survey (LCRS); the DURS is a fully three-dimensional, though shallower, survey, whilst the LCRS was carried out in six thin wedges of space. Because of the one-in-three sparse sampling used for DURS, the galaxy filaments of large-scale structure (LSS) are less clear here; the mean separation of ~25h-1Mpc for the richer filaments is consistent with the LCRS result, but the poorer filaments are not seen in the DURS. In contrast, the analysis clearly picks out SLSS and we find, as with the LCRS, that ~50 per cent of the galaxies lie within the SLSS in regions with overdensities of 5-10 times the mean galaxy density. It quantitatively demonstrates that SLSS is a major component of large-scale structure in the Universe. The SLSS is also confirmed as having statistical parameters similar to those for a sheet-like object, albeit a very irregular one with a highly inhomogeneous inner structure. The `mean-free path', or average separation between SLSS structures, is found to be Ds~50h-1Mpc. The inertia tensor analysis gives mean lengths, widths and thicknesses of ~20-40, 10 and 5h-1Mpc, respectively, for the clusters of SLSS. In particular, the largest great wall in the DURS is found to have a length of ~75h-1Mpc. Unlike the LCRS, the cluster mass function for the three-dimensional DURS has a high mass `tail' such a `tail' would constitute a quantitative signature for the presence of great walls. Finally, theoretical considerations would suggest that the results support arguments for the large-scale biasing of galaxies with respect to dark matter.

  11. Assessment and geomodelling of site effects along the eastern Enriquillo Plantain Garden Fault Zone in Haiti

    2016-12-01

    The last 2010 earthquake which hits Haiti killed more than 230,000 people, caused nearly 300,000 wounded and material damage of more than 8 billion dollars. This event whose epicenter was located in Léogâne, to the west of Port-au-Prince was triggered by a north dipping fault, the "Léogâne fault", near and to the north of the Enriquillo Plantain Garden Fault (EPGF), a very hazardous fault system crossing the southern part of the country. Several large international projects were carried out in Port-au-Prince and Léogâne. Our work which is done in the frame of a Belgian-Haitian collaboration project rather focused on an eastern region of Port-au-Prince, Fonds-Parisien and a site called Gros-Morne in the southeast of the city. The Fonds-Parisien area is crossed by the eastern part of EPGF. The north of the area is bordered by a sedimentary basin hosting the Azuei Lake and to the south it is bounded by the foothills of a mountain range, the "Massif de la Selle". The Gros-Morne zone is also situated nearby the EPGF and is limited to the north by the Cul-de-Sac plain, a sedimentary basin and to the south, by the foothills of the "Massif de la Selle". We performed local geophysical investigations to assess site effects 1) in areas relatively far from the epicenter, not intensively hit by the 2010 event, to see if they may fit for future construction projects, 2) on a hill in the southeastern part of Port-au-Prince that was affected by important destruction and secondary effects. Multichannel Analysis of Surface Waves (MASW), Horizontal to Vertical Spectral Ratio (HVSR) measurements as well as some Electrical Resistivity Tomography (ERT) were applied. The results were integrated to outline areas that are affected by site amplification and then combined into a 3D geomodel. For Fonds-Parisien, HVSR recordings show sharp and double amplitude peaks for sites located in the northern sedimentary basin along the shores of Azuei Lake, and consequently denotes a high

    2008-06-01

    Full Text Available A exportação de banana, na América, foi constituída sob uma base genética extremamente limitada: ao longo de setenta anos, uma só variedade de banana, a Gros Michel, foi praticamente a única a ser vendida nos mercados norte-americanos. Esta variedade produzia grandes cachos, resistentes ao transporte, e dotados de um sabor e de uma casca que os consumidores norte-americanos identificavam como pertencentes a uma banana de qualidade. Entretanto, a Gros Michel também se mostrou muito suscetível a um grande número de patógenos fúngicos, incluindo o Mal do Panamá e a Sigatoka. A dinâmica histórica ocasionada, durante a primeira metade do século XX, pela propagação desse fungo, acelerou o aumentou dos índices de desmatamento, desestabilizou os sistemas de vida rural, aumentou os riscos à saúde dos trabalhadores do campo, e limitou os rendimentos das principais companhias de comércio de banana. Tais epidemias impeliram o governo britânico e a United Fruit Company a estabelecerem programas de fitomelhoramento, durante a década de 1920, tendo como meta o desenvolvimento de uma banana para exportação, que fosse resistente ao Mal do Panamá. Contudo, a criação de um híbrido que fosse capaz tanto de prosperar nas zonas tropicais, quanto de encontrar aceitação no mercado norte-americano, se mostrou uma tarefa de difícil realização. A história dos programas de melhoramento revela uma das principais contradições da agricultura do século XX: os mesmos processos de produção massificada, que tendem a reduzir a diversidade biológica a nível local e regional, permaneciam dependentes do acesso a de um banco genético "global", para manter níveis lucrativos de produção.The export banana industry in Latin America and the Caribbean developed on a very narrow genetic base: a single variety, the Gros Michel, was the only banana variety mass marketed in the United States for at least seventy years.

  1. A Geophysical Study in Grand Teton National Park and Vicinity, Teton County, Wyoming: With Sections on Stratigraphy and Structure and Precambrian Rocks

    Science.gov (United States)

    Behrendt, John Charles; Tibbetts, Benton L.; Bonini, William E.; Lavin, Peter M.; Love, J.D.; Reed, John C.

    1968-01-01

    An integrated geophysical study - comprising gravity, seismic refraction, and aeromagnetic surveys - was made of a 4,600-km2 area in Grand Teton National Park and vicinity, Wyoming, for the purpose of obtaining a better understanding of the structural relationships in the region. The Teton range is largely comprised of Precambrian crystalline rocks and layered metasedimentary gneiss, but it also includes granitic gneiss, hornblende-plagioclase gneiss, granodiorite, and pegmatite and diabase dikes. Elsewhere, the sedimentary section is thick. The presence of each system except Silurian provides a chronological history of most structures. Uplift of the Teton-Gros Ventre area began in the Late Cretaceous; most of the uplift occurred after middle Eocene time. Additional uplift of the Teton Range and downfaulting of Jackson Hole began in the late Pliocene and continues to the present. Bouguer anomalies range from -185 mgal over Precambrian rocks of the Teton Range to -240 mgal over low-density Tertiary and Cretaceous sedimentary rocks of Jackson Hole. The Teton fault (at the west edge of Jackson Hole), as shown by steep gravity gradients and seismic-refraction data, trends north-northeast away from the front of the Teton Range in the area of Jackson Lake. The Teton fault either is shallowly inclined in the Jenny Lake area, or it consists of a series of fault steps in the fault zone; it is approximately vertical in the Arizona Creek area. Seismic-refraction data can be fitted well by a three-layer gravity model with velocities of 2.45 km per sec for the Tertiary and Cretaceous rocks above the Cloverly Formation, 3.9 km per sec for the lower Mesozoic rocks, and 6.1 km per sec for the Paleozoic (limestone and dolomite) and Precambrian rocks. Gravity models computed along two seismic profiles are in good agreement (sigma=+- 2 mgal) if density contrasts with the assumed 2.67 g per cm2 Paleozoic and Precambrian rocks are assumed to be -0.35 and -0.10 g per cm2 for the 2

  4. The evolution of mammography.

    Science.gov (United States)

    Gold, R H

    1992-01-01

    The history of mammography can be arbitrarily subdivided into three periods: The Age of Pioneers highlights the work of Salomon, Kleinschmidt, Warren, Vogel, Seabold, Gershon-Cohen, Leborgne, Egan, Gallager, Martin, Dodd, Strax and their colleagues; The Age of Technical Progress adds the names of Gould, Wolfe, and Gros and their co-workers; The Modern Era reflects the contributions of Price, Butler, Ostrum, Becker, Isard, Moskowitz, Sickles, Kopans, Homer, Tabár, and their associates. The ultimate success of mammography, the preeminent method of breast cancer screening, could not have been achieved without the intense vision, idealism, and scientific skill of its creators and nurturers. These investigators deserve a debt of gratitude that society can never adequately repay.

    The effects of ethylene on permeability and RNA and protein synthesis were assayed over a 6 to 26 hr period in tissue sections from avocado (Persea gratissima Gaertn. F., var. Fuerte), both pulp and peel of banana (Musa sapientum L., var. Gros Michel), bean endocarp (Phaseolus vulgaris L., var. Kentucky Wonder Pole beans) and leaves of Rhoeo discolor. Ethylene had no effect on permeability in 4 of the 5 tissues, but sometimes enhanced solute uptake in banana peel; it had either no effect or an inhibitory effect on synthesis of RNA and protein in sections from fruits of avocado and banana. Auxin (alpha-naphthalene acetic acid) stimulated synthesis of RNA and protein in bean endocarp and Rhoeo leaf sections, whereas ethylene inhibited both basal and auxin-induced synthesis. It is concluded that in these tissues the auxin effect is not an ethylene effect.

  9. AGRO100 inhibits activation of nuclear factor-kappaB (NF-kappaB) by forming a complex with NF-kappaB essential modulator (NEMO) and nucleolin.

    Girvan, Allicia C; Teng, Yun; Casson, Lavona K; Thomas, Shelia D; Jüliger, Simone; Ball, Mark W; Klein, Jon B; Pierce, William M; Barve, Shirish S; Bates, Paula J

    2006-07-01

    AGRO100, also known as AS1411, is an experimental anticancer drug that recently entered human clinical trials. It is a member of a novel class of antiproliferative agents known as G-rich oligonucleotides (GRO), which are non-antisense, guanosine-rich phosphodiester oligodeoxynucleotides that form stable G-quadruplex structures. The biological activity of GROs results from their binding to specific cellular proteins as aptamers. One important target protein of GROs has been previously identified as nucleolin, a multifunctional protein expressed at high levels by cancer cells. Here, we report that AGRO100 also associates with nuclear factor-kappaB (NF-kappaB) essential modulator (NEMO), which is a regulatory subunit of the inhibitor of kappaB (IkappaB) kinase (IKK) complex, and also called IKKgamma. In the classic NF-kappaB pathway, the IKK complex is required for phosphorylation of IkappaBalpha and subsequent activation of the transcription factor NF-kappaB. We found that treatment of cancer cells with AGRO100 inhibits IKK activity and reduces phosphorylation of IkappaBalpha in response to tumor necrosis factor-alpha stimulation. Using a reporter gene assay, we showed that AGRO100 blocks both tumor necrosis factor-alpha-induced and constitutive NF-kappaB activity in human cancer cell lines derived from cervical, prostate, breast, and lung carcinomas. In addition, we showed that, in AGRO100-treated cancer cells, NEMO is coprecipitated by nucleolin, indicating that both proteins are present in the same complex. Our studies suggest that abrogation of NF-kappaB activity may contribute to the anticancer effects of AGRO100 and that nucleolin may play a previously unknown role in regulating the NF-kappaB pathway.

  10. Quality differentiation of durable goods in secondary markets

    2003-06-01

    Full Text Available This paper presents a framework to study how changes in exogenous parameters, such as quality levels of new and used durables, affect the composition of durable good stocks. Our model extends the previous literature by including the endogeneity of prices and qualities. Our results could be applied to evaluate policies for controlling the externality level associated with the use and quality of durable goods in the long-term. We studied the characterization of the demand under a special situation: the consumer can choose the operation and/or maintenance level in the period the durable goods are new, which determines the quality levels for the subsequent periods. Comparative statics is performed to analyze the effects of exogenous variable change on the composition of durable stocks, and thus its impact on the externality level associated with each quality level. Contrary to most expectations, we provide an example in which the regulator imposes stricter quality standards for new durables to decrease negative externality associated with the use of durables. In this example, the comparative static results show that policies focusing only on new durable externality control may turn out to increase total externality, since stocks of older vintages may increase.Este trabalho apresenta uma estrutura para analisar as mudanças de parâmetros exógenos, tais como níveis de qualidade de bens duráveis novos e usados sobre a composição de estoques de bens duráveis.

    1988-01-01

    Eighty-nine kidneys of 81 infants and children with uretero-pelvic junction obstruction were investigated using ultrasonography (US), diuretic urography (DUR) and diuretic renography (DREN). Results of the US were false-negative in 14%. This can be avoided by ensuring that the patients get an amount of fluid appropriate to their age before the examination or by performing diuretic ultrasonography with frusemide. False-positive results were found with US in 15%, but obstruction was excluded by using the DUR and/or the DREN. During post-operative follow-up the DUS is useful and after 6 months the clearance with 123-iodine hippurate combined with the DREN should be performed. The administration of the Whitaker-test is unnecessary.

    2010-11-01

    Full Text Available Gaston Bachelard’s position toward the philosophy of Henri Bergson is most interesting. In La Dialectique de la durée (1936, Bachelard claims that “of Bergsonism we accept everything but continuity” and that the rest of his book will be an attempt to show the possibility of a “discontinuous Bergsonism”. In this paper, I focus on the reaction of Bachelard to works of Bergson such as the Essai sur les données immédiates de la conscience (1889, L’Evolution créatrice (1907, and Durée et simultanéité: à propos de la théorie d’Einstein (1922 and demonstrate that even though the conditions necessary for the possibility of a discontinuous Bergsonism are not the same ones which Bachelard had in mind when he accepted most of Bergsonism, their phenomenologies of the scientific spirit were analogous.

Les genres musicaux les plus populaires de l’époque – dance music et pop « bubble gum » – reflètent un intérêt décroissant pour le politique, notamment sur les questions ethniques et le problème de l’immigration. Face à la popularité d’artistes latinos comme Jennifer Lopez et Marc Anthony semblant annoncer une ère d’où aurait disparu toute discrimination raciale, le disque de Rage Against the Machine détonne singulièrement, de par son insistance à défendre des positions politiques tranchées. Au vu de la place prépondérante des questions d’immigration au début de l’an 2000, l’album de ce groupe engagé peut être envisagé comme un avertissement aux allures prophétiques contre la tentation de l’étourdissement dans une euphorie millénariste.

Specifically, we examined whether the effect would emerge with frontal rather than three-quarter views, after very brief exposure to caricatures during the learning phase and after modest rotations of faces dur...

    Fluctuations in nutrient availability profoundly impact gene expression. Previous work revealed postrecruitment regulation of RNA polymerase II (Pol II) during starvation and recovery in Caenorhabditis elegans, suggesting that promoter-proximal pausing promotes rapid response to feeding. To test this hypothesis, we measured Pol II elongation genome wide by two complementary approaches and analyzed elongation in conjunction with Pol II binding and expression. We confirmed bona fide pausing dur...

    The yeast plasma membrane protein Agp2 belongs to the family of amino acid transporters. It acts as a regulator that controls the expression of several uptake transporter genes such as DUR3 and SAM3 encoding two high-affinity polyamine permeases. agp2Δ mutants display extreme resistance to several cationic compounds including polyamines, the anticancer agent bleomycin, and cationic antifungal peptides. We propose that Agp2 might be involved in regulating the uptake of other cationic anticance...

    International audience; The laser drilling process is the main process used in machining procedures on aeronautic engines, espe- cially in the cooling parts. The industrial problematic is to reduce geometrical deviations of the holes and defects dur- ing manufacturing. The interaction between a laser beam and an absorbent metallic matter in the laser drilling regime involves thermal and hydrodynamical phenomenon. Their role on the drilling is not yet completely understood and a realistic simu...

  9. Complementation of the Yeast Model System Reveals that Caenorhabditis elegans OCT-1 Is a Functional Transporter of Anthracyclines.

    Directory of Open Access Journals (Sweden)

    Nicolas Brosseau

    Full Text Available The yeast plasma membrane protein Agp2 belongs to the family of amino acid transporters. It acts as a regulator that controls the expression of several uptake transporter genes such as DUR3 and SAM3 encoding two high-affinity polyamine permeases. agp2Δ mutants display extreme resistance to several cationic compounds including polyamines, the anticancer agent bleomycin, and cationic antifungal peptides. We propose that Agp2 might be involved in regulating the uptake of other cationic anticancer drugs. To date, an uptake transporter has not been reported for anthracyclines, a family of chemotherapeutic agents that are used for treating adult patients with acute myeloid leukemia. Herein, we develop assay conditions to monitor the uptake of the anthracycline doxorubicin into yeast cells and demonstrate for the first time that Agp2 is required for the drug uptake. Deletion of both the DUR3 and SAM3 genes reduced doxorubicin uptake, but not the deletion of either gene alone, while the agp2Δ mutant was severely compromised, suggesting that Agp2 controls the drug uptake via Dur3 and Sam3 and at least one additional transporter. Overexpression of DUR3 or SAM3 from the endogenous promoter rescued doxorubicin uptake into the sam3Δdur3Δ double mutant, consistent with a role for these transporters in the uptake of anthracyclines. We further show by cross-species complementation analysis that expression of the Caenorhabditis elegans oct-1 gene encoding an organic cation transporter restored full doxorubicin uptake in the agp2Δ mutant. Four separate variants of CeOCT-1 derived by substituting the amino acid residues Gln15, Cys31, Gln109 and Lys300 with alanine were stably expressed, but did not mediate doxorubicin uptake into the agp2Δ mutant. Moreover, we show that overexpression of CeOCT-1 sensitized parent yeast cells to doxorubicin, suggesting that CeOCT-1 related members might be key transporters to facilitate entry of anthracyclines into human

    Full Text Available Le rap en français peut être aujourd’hui considéré comme un univers professionnel établi, tout en étant une innovation relativement récente. Cet article montre que sa pérennisation est le fruit des rapports complexes entre trois générations d’artistes, et entre ces générations et les acteurs des industries musicales. Il s’appuie en particulier sur l’examen des conventions discographiques (refrains, collaborations, producteurs… privilégiées par les rappeurs qui se succèdent en France de 1990 à 2004. Une première génération émerge en 1990-1993 d’un pari ponctuel des grandes maisons de disques sur le rap. Une nouvelle génération de rappeurs, celle de 1994-1997, ne bénéfice pas d’un même contexte. Les clivages internes qui la traversent, liés à la médiation des radios, éclipsent ses tentatives de distinction à l’égard de la première génération. Dans le jeu de rivalités et de collaborations entre ces fractions de la scène rap naît un système d’accréditation informelle entre rappeurs qui marginalise une frange de la deuxième génération. La pratique professionnelle du rap connaît alors une autonomie relative, descriptible comme une concession au sein de l’industrie du disque. Enfin, les artistes qui accèdent à la notoriété à partir de 1998 se distinguent par leur rapport d’aspirant à l’égard d’un monde social désormais perçu comme prévisible. L’étude d’un tel processus d’intégration d’une nouvelle technique d’interprétation vocale dans les industries musicales françaises révèle la pertinence de l’outil conceptuel des générations sociologiques pour saisir le renouvellement des univers artistiques et des dynamiques professionnelles.French rap music is now an established industry, although it is still a recent innovation.

Integraram o estudo três conselheiros tutelares, um delegado de polícia e um promotor de justiça. Foram realizadas entrevistas individuais, os resultados foram analisados através da análise de conteúdo e indicaram que a notificação da violência envolve diversos procedimentos, dentre eles, a aplicação de medidas protetivas e a investigação policial. Os resultados também apontaram um aumento de casos sendo notificados pela ferramenta do disque 100 advindos da comunidade e atendidos pelos órgãos de defesa dos direitos. Por outro lado, ainda é pequeno o índice de notificações feitas pelos profissionais de saúde e educação. Torna-se importante promover maior conscientização tanto da sociedade em geral como de profissionais acerca da notificação da violência para que os órgãos competentes possam investigar as notificações e tomar as providências necessárias para que os direitos das crianças e dos adolescentes sejam garantidos.

    We model polymers by a chain of connected disks placed on the horizontal porous bronze working plate of an air table. Spatial and temporal fluctuations of the air stream at the bronze working plate act as a heat source for the polymer causing it to move and curl in a random fashion. The quenched randomness of the polymer's environment is modelled by placing heavy objects on the bronze plate. We find that the average radius of gyration of the chain, r, scales with the chain length N as rpropto N^{ν}, where ν=0.68± 0. 03, for three different densities of heavy objects. This effective exponent is below the exact value 3/4 for two-dimensional free SAWs. Nous modélisons des polymères par une chaîne de disques connectés sur le plateau d'une table soufflante. Les fluctuations temporelles et spatiales du flux d'air à travers le plateau poreux conduisent à des mouvements désordonnés de la chaîne, la table se conduisant alors comme un pseudo réservoir thermique. On crée un désordre gelé de l'environnement du polymère en plaçant des objets lourds sur la table. Nous trouvons que les variations du rayons de giration moyen de la chaîne, r, en fonction de sa longueur N sont bien traduites par une loi en puissance rsim N^{ν} où ν=0,68± 0,03, pour trois différentes densités d'objets lourds. La valeur effective de ν est inférieure à la valeur exacte 3/4 prévue par le modèle de marche autoévitante.

  15. Speed on the dance floor: Auditory and visual cues for musical tempo.

    2016-02-01

    Musical tempo is most strongly associated with the rate of the beat or "tactus," which may be defined as the most prominent rhythmic periodicity present in the music, typically in a range of 1.67-2 Hz. However, other factors such as rhythmic density, mean rhythmic inter-onset interval, metrical (accentual) structure, and rhythmic complexity can affect perceived tempo (Drake, Gros, & Penel, 1999; London, 2011 Drake, Gros, & Penel, 1999; London, 2011). Visual information can also give rise to a perceived beat/tempo (Iversen, et al., 2015), and auditory and visual temporal cues can interact and mutually influence each other (Soto-Faraco & Kingstone, 2004; Spence, 2015). A five-part experiment was performed to assess the integration of auditory and visual information in judgments of musical tempo. Participants rated the speed of six classic R&B songs on a seven point scale while observing an animated figure dancing to them. Participants were presented with original and time-stretched (±5%) versions of each song in audio-only, audio+video (A+V), and video-only conditions. In some videos the animations were of spontaneous movements to the different time-stretched versions of each song, and in other videos the animations were of "vigorous" versus "relaxed" interpretations of the same auditory stimulus. Two main results were observed. First, in all conditions with audio, even though participants were able to correctly rank the original vs. time-stretched versions of each song, a song-specific tempo-anchoring effect was observed, such that sped-up versions of slower songs were judged to be faster than slowed-down versions of faster songs, even when their objective beat rates were the same. Second, when viewing a vigorous dancing figure in the A+V condition, participants gave faster tempo ratings than from the audio alone or when viewing the same audio with a relaxed dancing figure. The implications of this illusory tempo percept for cross-modal sensory integration and

Methods The footshock stress-induced changes of behaviors and morphology of hippocampal CAl neurons during acute or chronic stress in rats, and the effects of CNTF administrated into bilateral hippocampus on the changes were observed with open field test, Nissl stain, Bielschowsky-Gros-Lawrentjew stain and electron microscope. Results The open field behaviors increased and morphology of hippocampal CA1 neurons did not change during acute stress in rats. The open field behaviors decreased and hippoampal CAl neuronal damage occurred during chronic stress. CNTF administrated into bilateral hippocampus had no effect on behavior and morphology of hippocampal CA1 neurons in control and acute stressful rats, but it significantly reduced hippocampal CAl neuronal damage and improved behavioral disorder induced by chronic stress. Conclusion CNTF could improve depressive behavior induced by chronic stress via protection of hippocampal CAl neurons.

    The family Anyphaenidae is composed by 56 genera and 542 species worldwide (World Spider Catalog 2015). These spiders, known as "ghost spiders", are wandering hunters living in a variety of environments, from forests to deserts, and can be quite abundant in different crops such as cotton, sorghum and rice (Brescovit 1996; Young & Edwards 1990; Taylor & Pfannenstiel 2008). They typically live on vegetation, among dead leaves or under loose bark and rocks (Richman & Ubick 2005) but synanthropic associations have been reported for a few species (Jiménez 1998; Guarisco 1999; Durán-Barrón et al. 2009). The genus Anyphaena has 81 species widely distributed in Asia, Central Europe, North America and Mexico (Brescovit 1996; Richman & Ubick 2005; World Spider Catalog 2015). The species from Noth America and Mexico were revised by Platnick (1974) who recognized four species groups (accentuata, celer, pectorosa and pacifica). Platnick (1977), Platnick & Lau (1975) and Brescovit & Lise (1989) complemented the revision of the genus in Central America. Presently, there are 27 species of Anyphaena recorded in Mexico (World Spider Catalog 2015), 24 of them from the celer group. Here, two new species of Anyphaena are described based in material collected during an inventory of spiders associated to houses in Mexico City, carried out by Durán-Barrón et al. (2009). Both species have the diagnostic characters of the members of the pacifica group as defined by Platnick (1974), such as the lack of leg coxal spurs and the presence of a lightly sclerotized atrium in the female epigynum. These species represent the first record of the pacifica group in Mexico. The occurrence of Anyphaenidae associated to houses was reported in Mexico by Durán-Barrón et al. (2009), who recorded Anyphaena obregon Platnick & Lau, 1975 and Hibana futilis (Banks, 1898) as frequent inhabitants inside houses. The species herein described are reported solely from urban areas and can be also characterized as

  20. Functional expression of a heterologous nickel-dependent, ATP-independent urease in Saccharomyces cerevisiae.

    In microbial processes for production of proteins, biomass and nitrogen-containing commodity chemicals, ATP requirements for nitrogen assimilation affect product yields on the energy producing substrate. In Saccharomyces cerevisiae, a current host for heterologous protein production and potential platform for production of nitrogen-containing chemicals, uptake and assimilation of ammonium requires 1 ATP per incorporated NH3. Urea assimilation by this yeast is more energy efficient but still requires 0.5 ATP per NH3 produced. To decrease ATP costs for nitrogen assimilation, the S. cerevisiae gene encoding ATP-dependent urease (DUR1,2) was replaced by a Schizosaccharomyces pombe gene encoding ATP-independent urease (ure2), along with its accessory genes ureD, ureF and ureG. Since S. pombe ure2 is a Ni(2+)-dependent enzyme and Saccharomyces cerevisiae does not express native Ni(2+)-dependent enzymes, the S. pombe high-affinity nickel-transporter gene (nic1) was also expressed. Expression of the S. pombe genes into dur1,2Δ S. cerevisiae yielded an in vitro ATP-independent urease activity of 0.44±0.01 µmol min(-1) mg protein(-1) and restored growth on urea as sole nitrogen source. Functional expression of the Nic1 transporter was essential for growth on urea at low Ni(2+) concentrations. The maximum specific growth rates of the engineered strain on urea and ammonium were lower than those of a DUR1,2 reference strain. In glucose-limited chemostat cultures with urea as nitrogen source, the engineered strain exhibited an increased release of ammonia and reduced nitrogen content of the biomass. Our results indicate a new strategy for improving yeast-based production of nitrogen-containing chemicals and demonstrate that Ni(2+)-dependent enzymes can be functionally expressed in S. cerevisiae.

    This paper reports the results obtained when a sludge age based control is incorporated in the biological process of a wastewater treatment plant (WWTP). Greater stability of the biological process is achieved when this control is implemented in WWTP of Molina de Segura. In particular biodiversity has increased and it has been possible to reduce and stabilize the secondary sludge production. An improvement of the sludge decantation and a reduction of the specific volumetric load of secondary clarifiers have also been observed. finally, costs have been reduced dur to the decrease of cationic polyelectrolyte consumption.

    Adults and nymphs of the Asian citrus psyllid, Diaphorina citri Kuwayama (Hemiptera: Psyllidae), were collected in the Guayaquil, Samborondón, and Durán cantons in coastal Ecuador. Psyllids were found in high numbers in citrus (Citrus spp., Sapindales: Rutaceae) and orange jasmine (Murraya exotica [L.] Jack, Sapindales: Rutaceae) trees within the Guayaquil-Samborondon-Duran conurbation; however, none was found during scoutings in the main citrus producing areas in coastal Ecuador. To the best of our knowledge, this is the first report of D. citri in Ecuador and the Pacific coastal plain of South America.

    2013-07-01

    Understanding large-scale patterns in flow intermittence is important for effective river management. The duration and frequency of zero-flow periods are associated with the ecological characteristics of rivers and have important implications for water resources management. We used daily flow records from 628 gauging stations on rivers with minimally modified flows distributed throughout France to predict regional patterns of flow intermittence. For each station we calculated two annual times series describing flow intermittence; the frequency of zero-flow periods (consecutive days of zero flow) in each year of record (FREQ; yr-1), and the total number of zero-flow days in each year of record (DUR; days). These time series were used to calculate two indices for each station, the mean annual frequency of zero-flow periods (mFREQ; yr-1), and the mean duration of zero-flow periods (mDUR; days). Approximately 20% of stations had recorded at least one zero-flow period in their record. Dissimilarities between pairs of gauges calculated from the annual times series (FREQ and DUR) and geographic distances were weakly correlated, indicating that there was little spatial synchronization of zero flow. A flow-regime classification for the gauging stations discriminated intermittent and perennial stations, and an intermittence classification grouped intermittent stations into three classes based on the values of mFREQ and mDUR. We used random forest (RF) models to relate the flow-regime and intermittence classifications to several environmental characteristics of the gauging station catchments. The RF model of the flow-regime classification had a cross-validated Cohen's kappa of 0.47, indicating fair performance and the intermittence classification had poor performance (cross-validated Cohen's kappa of 0.35). Both classification models identified significant environment-intermittence associations, in particular with regional-scale climate patterns and also catchment area, shape

    This study reveals that the entry into World War I in 1917 indexed the decisive transition to the modern period in American political consciousness, ushering in new objects of political discourse, a more rapid pace of change of those objects, and a fundamental reframing of the main tasks of governance. We develop a strategy for identifying meaningful categories in textual corpora that span long historic durées, where terms, concepts, and language use changes. Our approach is able to account for the fluidity of discursive categories over time, and to analyze their continuity by identifying the discursive stream as the object of interest.

  9. MBE growth of Quantum nanostructures for optoelectronics

    OpenAIRE

    2014-01-01

    Molecular Beam Epitaxy (MBE) is a powerful tech-nique for the fabrication of several self-assembled III-V nanostructures such as quantum rings, quantum dots, (Garcia 2013) and quantum wires that can cover a wide range of the spectrum from 0.98 ¿m to 1.6 ¿m. The possibility of performing in-situ, real-time, measurements of accumulated stress (¿¿) dur-ing growth of these nanostructures enables to achieve a deep understanding of the growth processes. For example, whereas quantum rings (QR) f...

    Una vez terminada la Segunda Guerra Mundial, los países aliados capitalistas comenzaron a negociar el nuevo sistema monetario internacional, con el fin de evitar las guerras cambiarias recientemente vividas. Esta negociación se formalizó en la Conferencia de Bretton Woods, donde quedo establecido el patrón oro-dólar, que duró hasta 1971. Ya transcurrieron 70 años desde este hecho, que puede entenderse como la última vez que los países discutieron la política económica mundial. Desde entonces,...

  18. La négociation : réflexions liminaires sur un concept insaisissable

    OpenAIRE

    Rougier, Bernard

    2014-01-01

    Le concept de négociation présente une double particularité: il est utilisé aussi bien par les acteurs que par les chercheurs et il revêt une dimension à la fois normative et empirique ; il connote la souplesse, le refus de la violence, la recherche du compromis d’une part, tout en servant à décrire la nature des interactions entre acteurs sociaux d’autre part. Son succès correspond à la crise des paradigmes « durs » (marxisme, fonctionnalisme, structuralisme) et à la redécouverte de la notio...
