    Full Text Available Cet article se propose de discuter des pratiques culinaires mises en œuvre par des étudiants étrangers lors de leur séjour temporaire en France. Pour ce faire, il examine de façon précise les pratiques et les discours de quatre étudiants rencontrés lors d’une enquête ethnographique menée à Lyon, en 2006-2007 : deux étudiantes chinoises, un étudiant marocain et un étudiant italien. Deux attitudes opposées mais hybrides se font jour. La première attitude que nous avons isolée révèle un désir déclaré de s’ouvrir au maximum à de nouvelles pratiques culinaires, mais elle s’accommode de retours à des pratiques conservatrices. La seconde attitude manifeste la volonté de conserver des pratiques culinaires qui sont présentées comme celles du pays d’origine. Pourtant ces pratiques apparaissent bien plus comme des pratiques d’hybridation, de sélection, de ruptures que des pratiques fidèles à un patrimoine familial ou régional. Il apparaît que les étudiants inventent en France un patrimoine culinaire individualisé.In this paper, we will review the cooking methods used by foreign students during their temporary stay in France. To that effect, we interviewed and observed the techniques of students we met in Lyon in 2006-2007 during an ethnographic survey: two Chinese students, one Moroccan and one Italian student. Two opposite but hybrid trends prevail. The first trend we observed shows a real desire to open itself to a maximum of culinary techniques. However, these techniques are modified by the native conservative influences. The second trend shows the desire to preserve the culinary methods of their country of origin. However, these techniques appear much more as a result of cross fertilization between radical and selective techniques than traditional ones inherited from a family or from a local background. Foreign students in France are in a class by itself.

    Because group-hunting arboreal ants spread-eagle insect prey for a long time before retrieving them, these prey can be coveted by predatory flying insects. Yet, attempting to rob these prey is risky if the ant species is also an effective predator. Here, we show that trying to rob prey from Azteca andreae workers is a fatal error as 268 out of 276 potential cleptobionts (97.1 %) were captured in turn. The ant workers hunt in a group and use the "Velcro®" principle to cling firmly to the leaves of their host tree, permitting them to capture very large prey. Exceptions were one social wasp, plus some Trigona spp. workers and flies that landed directly on the prey and were able to take off immediately when attacked. We conclude that in this situation, previously captured prey attract potential cleptobionts that are captured in turn in most of the cases.

  2. Nectar replenishment maintains the neutral effects of nectar robbing on female reproductive success of Salvia przewalskii (Lamiaceae), a plant pollinated and robbed by bumble bees.

    2017-04-01

    It has been suggested that the dynamics of nectar replenishment could differ for flowers after being nectar robbed or visited legitimately, but further experimental work is needed to investigate this hypothesis. This study aimed to assess the role of nectar replenishment in mediating the effects of nectar robbing on pollinator behaviour and plant reproduction. Plant-robber-pollinator interactions in an alpine plant, Salvia przewalskii , were studied. It is pollinated by long-tongued Bombus religiosus and short-tongued B. friseanus , but robbed by B. friseanus . Nectar production rates for flowers after they were either robbed or legitimately visited were compared, and three levels of nectar robbing were created to detect the effects of nectar robbing on pollinator behaviour and plant reproduction. Nectar replenishment did not differ between flowers that had been robbed or legitimately visited. Neither fruit set nor seed set was significantly affected by nectar robbing. In addition, nectar robbing did not significantly affect visitation rate, flowers visited within a plant per foraging bout, or flower handling time of the legitimate pollinators. However, a tendency for a decrease in relative abundance of the pollinator B. religiosus with an increase of nectar robbing was found. Nectar robbing did not affect female reproductive success because nectar replenishment ensures that pollinators maintain their visiting activity to nectar-robbed flowers. Nectar replenishment might be a defence mechanism against nectar robbing to enhance reproductive fitness by maintaining attractiveness to pollinators. Further studies are needed to reveal the potential for interference competition among bumble bees foraging as robbers and legitimate visitors, and to investigate variation of nectar robbing in communities with different bumble bee species composition. © The Author 2017.

  4. Floral nectar guide patterns discourage nectar robbing by bumble bees.

    Directory of Open Access Journals (Sweden)

    Anne S Leonard

    Full Text Available Floral displays are under selection to both attract pollinators and deter antagonists. Here we show that a common floral trait, a nectar guide pattern, alters the behavior of bees that can act opportunistically as both pollinators and as antagonists. Generally, bees access nectar via the floral limb, transporting pollen through contact with the plant's reproductive structures; however bees sometimes extract nectar from a hole in the side of the flower that they or other floral visitors create. This behavior is called "nectar robbing" because bees may acquire the nectar without transporting pollen. We asked whether the presence of a symmetric floral nectar guide pattern on artificial flowers affected bumble bees' (Bombus impatiens propensity to rob or access nectar "legitimately." We discovered that nectar guides made legitimate visits more efficient for bees than robbing, and increased the relative frequency of legitimate visits, compared to flowers lacking nectar guides. This study is the first to show that beyond speeding nectar discovery, a nectar guide pattern can influence bees' flower handling in a way that could benefit the plant.

  8. Promoting sustainable mobility by modelling bike sharing usage in Lyon

    Science.gov (United States)

    Tran, T. D.; Ovtracht, N.

    2018-04-01

    This paper aims to present a modelling of bike sharing demand at station level in the city of Lyon. Multiple linear regression models were used in order to predict the daily flows of each station. The data used in this project consists of over 6 million bike sharing trips recorded in 2011. The built environment variables used in the model are determined in a buffer zone of 300 meters around each bike sharing station. The results show that bike sharing is principally used for commuting purposes. An interesting finding is that the bike sharing network characteristics are important parameters to improve the prediction quality of the models. The present results could be useful for others cities which want to adopt a bike sharing system and also for a better planning and operation of existing systems. The approach in this paper can be useful for estimating car-sharing demand.

    2016-10-01

    Floral evolution is frequently ascribed to selection by pollinators, but may also be shaped by antagonists. However, remarkably few studies have examined geographic mosaics in resistance to floral antagonists or the consequences for other floral interactions. Gelsemium sempervirens experiences frequent nectar robbing in northern Georgia, but rarely in southern Georgia. We conducted common-garden experiments in both locations using genotypes from each region and measured robbing, pollinator attraction, floral attractive and defensive traits, and plant reproduction. Nectar robbing was more than four times higher in the north vs. south, and pollinator visits did not differ between gardens. Across both gardens, northern genotypes were half as likely to be nectar-robbed but received half as many pollinator visits as southern genotypes, suggesting evolution of resistance to robbing at a cost of reduced pollinator attraction. Plant-level traits, such as height and number of flowers, were more closely associated with resistance to robbing than floral size, shape, or chemistry. Northern genotypes had lower female and estimated male reproduction compared to southern genotypes at both locations, which could be due to costs of resistance to nectar robbing, or costs of adaptations to other biotic or abiotic differences between regions. Our study indicates that geographic variation can play a strong role structuring interactions with floral antagonists and mutualists and provides evidence consistent with the hypothesis that local resistance to nectar robbing imposes costs in terms of decreased pollinator attraction and reproduction. © 2016 Botanical Society of America.

Bombus atratus was a potentialpollinator while B. hortulanus and B. rubicundus collected nectar by robbing throughholes. We attribute behavioral differences to physical constraints. B. atratus has alonger glossa and a larger body size and is able to reach the nectaries, whereas B.hortulanus and B. rubicundus have shorter glossae and smaller bodies and probablymust rob nectar through holes at the base of flowers.

    The I-RobCELL project (Innovative Robotic Center with online Examination) is a concept of a totally automated cell for the production and control of small parts for the high-precision mechanical market. The I-RobCELL will play on 4 fields: 1) a totally digital driving of the fabrication process involving various fabrication processes for the same part, 2) the integration of non-destructive testing technologies based on ultrasound, 3) automated diagnostic of defects through the comparison between real-time measured values given by probes and references values stored in a database, and 4) on-line monitoring of the welding. The technology of ultrasonic testing without couplant substance between the transducer and the part to be tested, is being developed to be integrated to the I-RobCELL, other non-destructive testing like guided waves or X-ray tomography will be implemented in the future versions of the I-RobCELL. The I-RobCELL will occupy a 2-3 m"3 volume allowing a very accurate monitoring of the temperature and a high level of cleanliness. The I-RobCELL concept will prefigure the factory of the future.

    Nectar robbers affect host fitness in different ways and by different magnitudes, both directly and indirectly, and potentially constitute an important part of pollination interactions. The aim of this study was to assess the effect of nectar robbing on several variables that characterize the reproductive success of Lonicera etrusca, a pollinator-dependent plant with long, tubular flowers that produce abundant nectar. Using fluorescent powder dye as a proxy for pollen, the distance of pollen dispersal was compared for robbed and non-robbed flowers. Artificial nectar robbing treatments were applied to test its effects on four additional measures of reproductive success, namely the quantity of pollen exported, fruit set, seed/ovule ratio and seed weight. Nectar robbing was not found to have any significant negative consequences on female and male components of reproductive success as determined through the five variables that were measured. Although L. etrusca exhibits high levels of nectar robbing and nectar robbers are common floral visitors, no evidence was found of detrimental changes in the components of reproductive success. A combination of morphological and ecological mechanisms is proposed to explain how plants may compensate for the energetic loss caused by the nectar robbers. © The Author 2015.

    1999-01-01

    Although women's legal and marital status make them almost invisible in archival documents, what traces remain suggest that women participated in Lyon's medical marketplace in various ways and under various guises. At Lyon's municipally-funded poor hospital, the Hotel-Dieu, widows and wives of surgeons, repentant prostitutes, birth attendants, and cared for the destitute and sick of Lyon, in the capacity of midwives, physicians, surgeons, and barbers. Though the records almost always identify women practitioners simply as or by their first and last name, many of them engaged in the identical tasks as male practitioners. Outside of the hospital, wives acted as barbers or surgeons alongside or in place of their husbands when widowed. In the final analysis, municipal authorities accepted the help of female healers on the basis of their traditional medical knowledge, joint work identity with their practitioner-husbands, and proven skill.

  1. Spatio-temporal variation of nectar robbing in Salvia gesneriflora and its effects on nectar production and legitimate visitors.

    Cuevas, E; Rosas-Guerrero, V

    2016-01-01

    Nectar robbing occurs when floral visitors remove floral nectar through floral damage and usually without providing pollination in return. Even though nectar robbing may have negative, neutral or even positive effects on plant fitness, few studies have investigated temporal and spatial variation in robbing rate and their consequences, particularly in the tropics. In this study, robbing levels were estimated during 3 years in four populations of Salvia gesneriflora, a hummingbird-pollinated shrub endemic to central Mexico that is mainly robbed by birds, carpenter bees and bumblebees. The effect of robbing on nectar availability, flower longevity and on visitation rate by floral visitors was also evaluated. Our results indicate great variation in robbing levels across years and populations and a positive relationship between robbing level and flower abundance per population. Moreover, our results show that nectar availability is about eight times higher in unrobbed flowers than in robbed flowers, and that nectar robbers prefer younger flowers, although lifespan of robbed and unrobbed flowers did not differ statistically. Primary and secondary nectar robbers showed a higher visitation rate compared to legitimate visitors, and neither legitimate nor illegitimate floral visitors seem to discriminate between robbed and unrobbed flowers. These results suggest that robbers may respond to food availability and that no floral visitors apparently could differentiate between robbed and unrobbed flowers. Finally, results show that nectar robbers prefer the youngest flowers, which suggests that strong competition for access to nectar between pollinators and robbers might occur, mainly at the first stages of the flowers. © 2015 German Botanical Society and The Royal Botanical Society of the Netherlands.

  2. Nectar robbing, forager efficiency and seed set: Bumblebees foraging on the self incompatible plant Linaria vulgaris (Scrophulariaceae)

    Stout, Jane C.; Allen, John A.; Goulson, Dave

    2000-07-01

    In southern England, Linaria vulgaris (common yellow toadflax) suffers from high rates of nectar robbery by bumblebees. In a wild population of L. vulgaris we found that 96 % of open flowers were robbed. Five species of bumblebee were observed foraging on these flowers, although short-tongued species ( Bombus lapidarius, B. lucorum and B. terrestris) robbed nectar whilst longer-tongued ones behaved as legitimate pollinators ( B. hortorum and B. pascuorum). Nectar rewards were highly variable; on average there was less nectar in robbed than in unrobbed flowers, but this difference was not statistically significant. The proportion of flowers containing no nectar was significantly higher for robbed flowers compared with unrobbed flowers. Secondary robbers and legitimate pollinators had similar handling times on flowers and, assuming they select flowers at random to forage on, received approximately the same nectar profit per minute, largely because most flowers had been robbed. There was no significant difference in the number of seeds in pods of robbed flowers and in pods of flowers that were artificially protected against robbing. However, more of the robbed flowers set at least some seed than the unrobbed flowers, possibly as a consequence of the experimental manipulation. We suggest that nectar robbing has little effect on plant fecundity because legitimate foragers are present in the population, and that seed predation and seed abortion after fertilization may be more important factors in limiting seed production in this species.

    The net consequence of nectar robbing on reproductive success of plants is usually negative and the positive effect is rarely produced. We evaluated the influence of nectar robbing on the behaviour of pollinators and the reproductive success of Tecomella undulata (Bignoniaceae) in a natural population. Experimental pollinations showed that the trees were strictly self-incompatible. The three types of floral colour morphs of the tree viz. red, orange and yellow, lacked compatibility barriers. The pollinators (Pycnonotus cafer and Pycnonotus leucotis) and the robber (Nectarinia asiatica) showed equal preference for all the morphs, as they visited each morph with nearly equal frequency and flower-handling time. The sunbirds caused up to 60% nectar robbing, mostly (99%) by piercing through the corolla tube. Although nectar is replenished at regular intervals, insufficient amount of nectar compelled the pollinators to visit additional trees in bloom. Data of manual nectar robbing from the entire tree showed that the pollinators covered lower number of flowers per tree (5 flowers/tree) and more trees per bout (7 trees/bout) than the unrobbed ones (19 flowers/tree and 2 trees bout). The robbed trees set a significantly greater amount of fruits than the unrobbed trees. However, the number of seeds in a fruit did not differ significantly. The study shows that plant-pollinator-robber interaction may benefit the self-incompatible plant species under conditions that increases the visits of pollinators among the compatible conspecifics in a population.

    Full Text Available Le tourisme est au cœur des processus de valorisation des territoires urbains. Le patrimoine – pilier majeur de la touristification – tend à prendre un caractère marchand, en tant que produit à valoriser économiquement dans un contexte de villes en compétition. À partir de l’analyse de deux centres urbains en mutations – Lyon et Pékin –, cette recherche montre d’une part l’usage marchand du patrimoine, produit et mobilisé par les pouvoirs publics. D’autre part, ce papier questionne la notion d’authenticité – centrale dans les discours sur la mise en valeur du patrimoine. Apparaissant comme inopérante du point de vue heuristique, nous faisons l’hypothèse qu’elle détient une dimension proprement « fétiche », concourant à la perception déformée de la réalité des rapports sociaux en jeu dans la production patrimoniale.Tourism lies at the heart of urban territorial valorization. The urban heritage – itself a major pillar of urban tourism – is becoming increasingly commodified, within a context of generalized urban competition. Based on the analysis of two changing urban centers – Lyon and Beijing – this paper analyzes the commodified valorization of heritage, produced by entrepreneurial urban governments, and challenges the notion of « authenticity », itself central to discourses on the valorization of urban heritage. This concept of authenticity bears very little heuristic value, and is itself a « fetish », resulting from a deformed perception of reality under the social conditions of capitalism.

    Sustainable production of target compounds such as biofuels and high-value chemicals for pharmaceutical, agrochemical, and chemical industries is becoming an increasing priority given their current dependency upon diminishing petrochemical resources. Designing these strains is difficult, with current methods focusing primarily on knocking-out genes, dismissing other vital steps of strain design including the overexpression and dampening of genes. The design predictions from current methods also do not translate well-into successful strains in the laboratory. Here, we introduce RobOKoD (Robust, Overexpression, Knockout and Dampening), a method for predicting strain designs for overproduction of targets. The method uses flux variability analysis to profile each reaction within the system under differing production percentages of target-compound and biomass. Using these profiles, reactions are identified as potential knockout, overexpression, or dampening targets. The identified reactions are ranked according to their suitability, providing flexibility in strain design for users. The software was tested by designing a butanol-producing Escherichia coli strain, and was compared against the popular OptKnock and RobustKnock methods. RobOKoD shows favorable design predictions, when predictions from these methods are compared to a successful butanol-producing experimentally-validated strain. Overall RobOKoD provides users with rankings of predicted beneficial genetic interventions with which to support optimized strain design.

    2011-03-01

    Full Text Available Abstract The Lyon Brace, or adjustable multi-shell brace, has been used for more than 60 years. The use and function of the Lyon Brace includes: - The utilization of one or two corrective plaster casts, which enables a true lengthening of the concave ligaments. - An oriented CAD-CAM moulding in 3D auto correction after the removal of the plaster cast. - A blueprint adapted to Lenke's classification. - A specific physiotherapy program. Background Pierre Stagnara created the Lyon Brace in 1947. The brace has the following characteristics: - It adjusts to allow for a child's growth of up to seven centimetres and for an increase in weight of up to seven kilograms. - It is 'active' in that the rigidity of the PMM (polymetacrylate of methyl structure stimulates the user to auto-correct. The active axial auto-correction decreases the pressures of the brace on the trunk. - It is decompressive in that the effect of extension between the two pelvic and scapular girdles decreases the pressure on the intervertebral disc allowing for more effective pushes in the other planes. - It is symmetrical making it both more aesthetically pleasing and easier to build. - It is stable at both shoulders and pelvic girdle, facilitating the intermediate 3D corrections. - It is transparent. The pressure of the shells on the skin can be directly controlled so "pads" are usually not necessary. Brace description Two metal bars are fixed vertically, one anterior the other posterior and all shells are attached from the bottom to the top in this order: - Two pelvic shells ensure an optimal stability of the brace. - One lumbar shell T12-L4, which can be either independent or extending, at the abdominal chondrocostal level. - One thoracic shell at the level of the thoracic convexity. - One opposite thoracic shell used as a counter push. - One shoulder balance shell on the side of the thoracic convexity. Long term follow up results This is a retrospective study of 1,338 completed

    2013-01-01

    The objective of the project ImPAC Lyon was to evaluate the thermal, physico-chemical and microbiological impacts potentially associated to a groundwater heat pump (GSHP). It is based on two experimental parts: one in laboratory and the other on land (8. district of Lyon). The main results indicate that: - on land, no physical and microbiological disturbances were revealed in the conditions of the study (range of temperature; 16-24 deg. C). Only thermal disturbances were observed; - the experimental approach of laboratory displayed in this study (range of temperature: 15-25 deg. C) indicates a certain influence of the temperature on the native bacterial microflora, but not enough to compromise the ecosystem balance, However, other environmental conditions have to be studied (T >25 deg. C and T< 15 deg. C, different redox conditions); - behaviour of pathogenic bacteria and organic pollutants in the presence of thermal modifications could not be observed in Lyon (no pollutions observed). It will also have to be studied in new projects; - the bad sizing of ta plant (which seems to be a significant practice in urban areas with little space) could lead to thermal disturbances and a progressive heating of the aquifer at an inter-annual scale. In these conditions, it seems necessary to pursue the works begun in Lyon by treating the other ranges of temperatures. (authors)

  15. Recognition of a heritage in danger: rammed-earth architecture in Lyon city, France

    Alex, Dorothée

    2018-04-01

    Historically, man has built with what he had underfoot: if the earthen construction is a tradition of 11 000 years old, the technique of the rammed earth (earth rammed in a formwork) is relatively new since it appeared for the first time in Tunisia in 814 BC. Exported in France, rammed earth is established mainly in Rhône-Alpes Region which has an ideal soil, rich in gravel, sand, silt and clay. Traditionally associated with the rural world, rammed earth heritage is also present in urban centers. The city of Lyon is one of the rare European cities to concentrate a large proportion of rammed earth buildings: the inventories made show that they are present in almost all the districts as well as in the suburban areas. This high density could be explained by the phenomenon of rural exodus experienced by Lyon during the nineteenth century. The agricultural populations, attracted by the prosperity of the city, then settled at the doors of this city, bringing their know-how by building with the cheaper and easier material available: earth. Rammed earth buildings are therefore located on bounder areas between the countryside and the city. They are thus found on lands that were once outside the city walls. With the advent of the industrial era at the end of the 19th century and the appearance of concrete, rammed earth constructions gradually disappeared. The constructions that we see today are therefore prior to 1900. Varied, ranging from detached houses to the 6-storey buildings, they stand as a testimony to a know-how that finds a particular resonance today, while the environmental and economic concerns are at the forefront. Little known, they constitute a heritage in danger that should be rediscovered.

    Full Text Available Accidental or intentional release of radioactive materials into the living or working environment may cause radioactive contamination. In nuclear medicine departments, radioactive contamination is usually due to radionuclides which emit high energy gamma photons and particles. These radionuclides have a broad range of energies and penetration capabilities. Rapid detection of radioactive contamination is very important for efficient removing of the contamination without spreading the radionuclides. A quick scan of the contaminated area helps health physicists locate the contaminated area and assess the level of activity. Studies performed in IR Iran shows that in some nuclear medicine departments, areas with relatively high levels of activity can be found. The highest contamination level was detected in corridors which are usually used by patients. To monitor radioactive contamination in nuclear medicine departments, RadRob15, a contamination detecting robot was developed in the Ionizing and Non-ionizing Radiation Protection Research Center (INIRPRC. The motor vehicle scanner and the gas radiation detector are the main components of this robot. The detection limit of this robot has enabled it to detect low levels of radioactive contamination. Our preliminary tests show that RadRob15 can be easily used in nuclear medicine departments as a device for quick surveys which identifies the presence or absence of radioactive contamination.

    2015-01-01

    Electric power grid operators are facing new challenges, including rising energy consumption and emissions, the need to integrate renewable energy sources, and the emergence of electric vehicles. There is an urgent need to make grids safer, more efficient, environmentally 'greener', and more flexible. In a word: smarter. Schneider Electric has teamed with 4 partners (GEG, GDF Suez, ERDF and GINP) and 6 others on the GreenLys project, the first full-scale smart grid demonstration project in France. Partially financed by the French Environment and Energy Management Agency (ADEME), the consortium has developed an experimental technology platform being tested in the cities of Lyon and Grenoble, ultimately involving 1,000 residential customers and 40 commercial building sites. The goal is to standardize and showcase a functional smart grid by 2015, setting the stage for widespread deployment. The GreenLys project is testing innovative solutions from energy generation to end use. At the grid level this includes new analysis tools, next generation substation automation equipment, and communication with smart meters at consumer locations. The grid will be self-healing, quickly reconfiguring itself to maintain the supply of electricity. It will also incorporate decentralised energy generation based on renewables or natural gas, as well as the potential to use stored energy in electric vehicles. At the end-consumer level, a variety of new technologies are applied to engage businesses and homeowners. The cloud-based Demand-Side Operation platform will enable participation in programs like demand response that offer financial incentives for adjusting energy consumption when required. Such programs will help energy users optimize their energy bill and encourage energy-efficient practices. Offering their energy flexibility to the smart grid will also help alleviate peak demand and compensate for the intermittency of large-scale renewable energy production. For commercial

    The U.S. Geological Survey (USGS) Special Applications Science Center (SASC) produced an image base map showing high-resolution remotely sensed data over Lyons, Colorado—a city that was severely affected by the flood event that occurred throughout much of the Colorado Front Range in September of 2013. The 0.5-meter WorldView-2 data products were created from imagery collected by DigitalGlobe on September 13 and September 24, 2013, during and following the flood event. The images shown on this map were created to support flood response efforts, specifically for use in determining damage assessment and mitigation decisions. The raw, unprocessed imagery were orthorectified and pan-sharpened to enhance mapping accuracy and spatial resolution, and reproduced onto a cartographic base map. These maps are intended to provide a snapshot representation of post-flood ground conditions, which may be useful to decisionmakers and the general public. The SASC also provided data processing and analysis support for other Colorado flood-affected areas by creating cartographic products, geo-corrected electro-optical and radar image mosaics, and GIS water cover files for use by the Colorado National Guard, the National Park Service, the U.S. Forest Service, and the flood response community. All products for this International Charter event were uploaded to the USGS Hazards Data Distribution System (HDDS) website (http://hdds.usgs.gov/hdds2/) for distribution.

    Since the end of the First World War the Rockefeller Foundation has spearheaded a large-scale programme in the field of education for the health professions (doctors and nurses). In several countries throughout the world, but with its efforts concentrated on Europe, it has financed schools, constructed information networks, granted research scholarships and awarded training bursaries. In so doing it has not, however, been in the business of propagating an irresistible "American model," nor has it pursued a huge undertaking in disinterested aid. Through an attempt to contextualize these programmes, to bring to light the existence of common reference points, to retrace the work with local participants and to appraise cleavages within the philanthropic apparatus, this article proposes a fine-grained reading of the role of the Rockefeller Foundation at the Faculté de Médecine (Faculty of Medicine) and the Ecole d'Infirmières et d'assistantes sociales (Training School for Nurses and Social Workers) in Lyon between 1917- and 1940. It analyses these institutions in terms of the transactions, negotiations and appropriations that highlight their joint-venture character and it identifies their varied impact.

  9. Assessing the accuracy of weather radar to track intense rain cells in the Greater Lyon area, France

    Renard, Florent; Chapon, Pierre-Marie; Comby, Jacques

    2012-01-01

    The Greater Lyon is a dense area located in the Rhône Valley in the south east of France. The conurbation counts 1.3 million inhabitants and the rainfall hazard is a great concern. However, until now, studies on rainfall over the Greater Lyon have only been based on the network of rain gauges, despite the presence of a C-band radar located in the close vicinity. Consequently, the first aim of this study was to investigate the hydrological quality of this radar. This assessment, based on comparison of radar estimations and rain-gauges values concludes that the radar data has overall a good quality since 2006. Given this good accuracy, this study made a next step and investigated the characteristics of intense rain cells that are responsible of the majority of floods in the Greater Lyon area. Improved knowledge on these rainfall cells is important to anticipate dangerous events and to improve the monitoring of the sewage system. This paper discusses the analysis of the ten most intense rainfall events in the 2001-2010 period. Spatial statistics pointed towards straight and linear movements of intense rainfall cells, independently on the ground surface conditions and the topography underneath. The speed of these cells was found nearly constant during a rainfall event, but depend from event to ranges on average from 25 to 66 km/h.

Cirurgiões cardíacos foram logo atraídos pela técnica robótica devido a possível aplicação com reduzido caráter invasivo; esperava-se menor trauma cirúrgico e redução da dor, morbidade, tempo de internação e custo do procedimento. Atualmente, de forma restrita e em casos selecionados, robôs são usados para revascularização do miocárdio e implante de marcapasso em cirurgias cardíacas totalmente endoscópicas; podendo também constituir apoio visual na retirada de artéria torácica interna, reconstrução valvar mitral e correção de defeitos congênitos. Utilizando o robô auxiliar AESOP® para controle do videotoracoscópio, com controle vocal por meio do sistema HERMES®, temos realizado dissecção da artéria torácica interna, implante de eletrodo ventricular esquerdo e abordagem de defeitos congênitos na cirurgia de correção. Apesar do entusiasmo científico inicial com a cirurgia robótica, ainda não existe evidência clara de superioridade desta técnica em relação à operação convencional, em termos de resultado. Isto se aplica também ao custo, pois o investimento inicial na aquisição de sistema cirúrgico completo (console, controle de vídeo, instrumental provavelmente é compensado após muitos procedimentos e longo intervalo. Mas é certo que a cirurgia robótica terá um lugar no futuro, possibilitando aprendizagem, telepresença e realização de procedimentos pouco invasivos, embora complexos.The development of robotic systems for surgery started in the 80's, motivated by the US army's need for surgical procedure in

  13. Petrofabric changes in heated and irradiated salt from Project Salt Vault, Lyons, Kansas

    Rock salt was heated and irradiated in situ by implanted radioactive wastes during the Project Salt Vault experiment which was carried out at Lyons, Kansas, in the abandoned Carey Salt mine between 1965 and 1967. It was found that irradiation results in coloration of the salt, producing colors ranging from blue-black nearest the radiation source, to pale blue and purple farther from the source. Bleached areas are common in the radiation-colored salt, many representing trails produced by the migration of fluid inclusions towards the heat source. These visible trails are thought to have formed during the cooling down of the salt after the removal of the heaters and radiation sources. The distribution of primary structures in the salt suggests that little migration, if any, occurred during the course of the experiment. It is proposed that radiolysis of the brine within the inclusions may have led to the production of gases which impeded or prevented migration. Evidence of strain was observed in slip planes at 4 in. (10 cm) and between 5.5 and 10 in. (13.5 to 25.4 cm) from the array hole. Deformed bleached areas in the salt between the areas were slip planes are developed suggest that slight plastic deformation or flow may have occurred at 6 in. (15 cm) from the array hole. Differential thermal analysis shows that the maximum amount of stored energy also occurs at 6 in. (15 cm) from the array hole. This region may therefore represent the zone where the combined effect of stress and radiation was greatest

    Full Text Available In the 1950s, the Era of the Great Depression, archaeology in the United States enjoyed an enormous boost, both in the substance of its findings on the Precolumbian past and in the development of its methods and proce­dures. Edwin A. Lyon has laid out the story of all this in a book that is a major contribution to the history of the archaeological discipline in this country. The context of this story is in the American South, most specifically the Southeastern United States, or the 'Old South', that part of the country that was the heart of the Confederacy; and it is important to remember that the South has had a history significantly separate and distinct from that of the rest of the nation. This separateness, rooted in its plantation economy and the associated institution of slavery, was further fostered by the Civil War and its aftermath of hardships. These hardships lasted until the 1930s and the economic depression when they began to be ameliorated by the Rooseveltian political and socioeconomic measures known collectively as the 'New Deal'. The policies of the New Deal began those transformations which continued through World War II and beyond. Crucial to these transformations were the building of power dams and rural electrification, soil erosion control and agricultural modernization, and a host of public building programs. All of this went forward with Federal Relief employment. Less tangible but nonetheless important benefits were in the cultural sphere: the arts, drama, writing. history - and of particular importance to us here. archaeology.

    We report the first experience of Lyon's university hospital regarding renal denervation to treat patients with resistant essential hypertension. Over a one-year period, 17 patients were treated (12 men, 5 women) with renal denervation. Baseline characteristics were as follows: age 56.5±11.5 years, BMI 33±5kg/m(2) and ambulatory blood pressure 157±16/87±13mmHg with 4.2±1.5 anti-hypertensive treatment. We did not observe intra-operative or early complications. After a median follow-up of 3 months and with the same anti-hypertensive treatment, office systolic blood pressure (SBP) and diastolic blood pressure (DBP) decrease respectively of 20±15 (P<0.001) and 10±13mmHg (P=0.014) (n=17). After six months of follow-up, ambulatory blood pressure (ABPM) decrease of 17.5±14.9mmHg (P=0.027) for SBP and of 10.5±9.6mmHg (P=0.029) for DBP (n=6). Among these patients, five of them were controlled (ABPM inferior to 130/80mmHg) and electrical left ventricular hypertrophy indexes decreased: R wave in aVL lead of 4±3mm (P=0.031), Sokolow index of 3±3mm (P=0.205), Cornell voltage criterion of 9±7mm (P=0.027) and Cornell product of 1310±1104 (P=0.027). Our results are in accordance with data from other centers. On average blood pressure decreases significantly but important inter individual variations are observed. The procedure seems safe.

    The tissue and cell bank of the HCL (Hospices Civils de Lyon) has, since 10 June 1999, consisted of two sections with related activities: cell culture for the Skin Substitutes Laboratory (Laboratoire des Substituts Cutanés, LSC) and preservation of corneas at 31 degrees C for the Cornea Bank. As the LSC had been ISO 9001 certified since March 1997 our aim, since merger, was to raise the Cornea Bank to the same level of quality as the LSC, so as to coincide with the renewal of the LSC certificate in February 2000. The methods we used (project, quality control, analysis and process optimization) led us to receive official certification only nine months after the merger. The procedure started with a program of quality control at the Cornea Bank from February 1999 onwards, in order to list the work and equipment required, evaluate its documentation system and what was needed to incorporate this new activity into the existing system of quality assurance at the LSC. On the 7th March 2000, the Tissue and Cell Bank of the HCL obtained an ISO 9001 certificate for its combined functions. As well as achieving our objectives and the strong points highlighted by the auditor during the renewal process, this quality assessment revealed many advantages: improvements in the conservation of corneas, economies in staff replacement and reductions in both the cost of maintaining quality, the cost of the corneas themselves, etc. The decree 'Banque' no. 99-741 of 30th August 1999, which put in place the system of authorization of tissue banks in France, demands quality control. Our application for certification which started in early 1999 had anticipated this regulation. This helped us enormously when compiling the dossier accompanying the official request and was an essential element in obtaining the favourable response of the ASSAPS on 21 June 2000.

  3. Immediate effects of nectar robbing by Palestine sunbirds (Nectarinia osea) on nectar alkaloid concentrations in tree tobacco (Nicotiana glauca).

    Plant secondary metabolites (PSMs), such as alkaloids, are often found in many parts of a plant, including flowers, providing protection to the plant from various types of herbivores or microbes. PSMs are also present in the floral nectar of many species, but typically at lower concentrations than in other parts of the plant. Nectar robbers often damage floral tissue to access the nectar. By doing so, these nectar robbers may initiate an increase of PSMs in the floral nectar. It is often assumed that it takes at least a few hours before the plant demonstrates an increase in PSMs. Here, we addressed the question of whether PSMs in the floral tissue are immediately being released into the floral nectar following nectar robbing. To address this research question, we investigated whether there was an immediate effect of nectar robbing by the Palestine Sunbird (Nectarinia osea) on the concentration of nectar alkaloids, nicotine and anabasine, in Tree Tobacco (Nicotiana glauca). We found that the concentration of anabasine, but not nicotine, significantly increased in floral nectar immediately following simulated nectar robbing. These findings suggest that nectar robbers could be ingesting greater amounts of PSMs than they would if they visit flowers legitimately. As a consequence, increased consumption of neurotoxic nectar alkaloids or other PSMs could have negative effects on the nectar robber.

  5. Human Capital and Self-Entrepreneurship. The Concept of Robbed Time.

    The notions of ″human capital″ and ″self-entrepreneurship″ are by now widespread. The present work takes a critical look at their pervasive acceptance and stresses the self-exploitation to which they give rise. The concept of self-entrepreneurship needs to take into account, in fact, the nature of a revolution in temporal phenomenology. This revolution not only blurs the distinction between time dedicated to life and time dedicated to one's profession. It means that time spent on whatever is traditionally irrelevant to work is potentially time robbed from successful self-entrepreneurship. An analysis is made, lastly, of the relationship between body and ″bio-labor″, recognizable in the emergence of new forms of manual labor. Emblematic, in this sense, is gestational surrogacy. This provides an opportunity to rediscover the pregnancy of M. Foucault's biopolitical interpretation of neoliberalism as opposed to the more recent category of ″psychopolitics″ defined by B.C. Han. In the current scenario, indeed, the body maintains a role that remains as central as it is paradoxical, on account of its configuration as an ″entrepreneurial resource″.

    Robbing and bartering (RB) is a behavioral practice anecdotally reported in free-ranging commensal macaques. It usually occurs in two steps: after taking inedible objects (e.g., glasses) from humans, the macaques appear to use them as tokens, returning them to humans in exchange for food. While extensively studied in captivity, our research is the first to investigate the object/food exchange between humans and primates in a natural setting. During a 4-month study in 2010, we used both focal and event sampling to record 201 RB events in a population of long-tailed macaques (Macaca fascicularis), including four neighboring groups ranging freely around Uluwatu Temple, Bali (Indonesia). In each group, we documented the RB frequency, prevalence and outcome, and tested the underpinning anthropogenic and demographic determinants. In line with the environmental opportunity hypothesis, we found a positive qualitative relation at the group level between time spent in tourist zones and RB frequency or prevalence. For two of the four groups, RB events were significantly more frequent when humans were more present in the environment. We also found qualitative partial support for the male-biased sex ratio hypothesis [i.e., RB was more frequent and prevalent in groups with higher ratios of (sub)adult males], whereas the group density hypothesis was not supported. This preliminary study showed that RB is a spontaneous, customary (in some groups), and enduring population-specific practice characterized by intergroup variation in Balinese macaques. As such, RB is a candidate for a new behavioral tradition in this species.

    Methicillin-resistant Staphylococcus aureus (MRSA) is involved in community-acquired and nosocomial diseases. The means of MRSA transmission and dissemination in the community remain uncertain. Studies have shown that public transport systems could be a source of MRSA and may serve as a potential source for community-acquired MRSA infections. This study aimed to investigate MRSA contamination on Lyon's metropolitan network (Métro) in France. Hand-touched surfaces were sampled with sterile swabs (Transystem(®)) during a 1-day transversal study by collecting 50 samples in seven hub stations and two trains for each of the four Métro lines. Then, during a longitudinal study, one sample was collected twice daily for 30 consecutive days in the busiest and most congested hub station. All swabs were incubated in enrichment medium for 24 h and then each suspension was plated onto a chromogenic selective medium for MRSA. After 24 h at 36 °C, all presumptive MRSA colonies were tested using VITEK(®) MS to confirm identification as S. aureus as well as by Alere™ PBP2a Culture Colony Test and mecA/mecC PCR to check methicillin resistance. Of the 110 swabs tested, 24 presumptive MRSA colonies were isolated, of which 2 were confirmed as S. aureus by VITEK(®) MS. These two isolates were tested negative using the PBP2a Culture Colony Test and PCR. Unlike other foreign cities such as Lisbon, the current data suggest a low level of MRSA contamination of hand-touched surfaces on Lyon's Métro. This should be put in perspective with the low level of MRSA colonisation in the French community. Copyright © 2016 Elsevier B.V. and International Society of Chemotherapy. All rights reserved.

    Full Text Available Resumen: El uso de plataformas robóticas de movimiento en simuladores de vehículos y aplicaciones de Realidad Virtual es relativamente habitual. Sin embargo, el ajuste de los algoritmos que controlan su funcionamiento, denominados algoritmos de washout, no es sencillo y requiere de numerosas pruebas hasta obtener una apropiada fidelidad de movimiento. Disponer de herramientas que permitan simular plataformas de movimiento puede permitir simplificar esta tarea. Es por ello que este trabajo presenta un método para la caracterización y simulación de manipuladores robóticos mediante filtros digitales de segundo orden, sencillo de implementar y ajustar a partir de una caracterización previa. El simulador se construye con el objetivo de permitir la simulación rápida de manipuladores robóticos y se ejemplifica con una plataforma de dos grados de libertad, aunque el método propuesto podría emplearse en otros dispositivos. En las pruebas realizadas se valida la precisión y velocidad de la simulación, concluyéndose que se obtiene una fidelidad satisfactoria y una velocidad de simulación elevada que permite emplear el simulador como sustituto del hardware real con algoritmos de washout. Abstract: Robotic motion platforms are used in many vehicle simulators and Virtual Reality applications. However, the set-up of the so-called washout algorithms that control the generation of self-motion is a hard process, since a great deal of tests need to be performed before reaching a proper motion fidelity. The availability of simulation tools eases this tuning task. Therefore, a motion platform characterization and simulation method is proposed in this paper. The method relies on second order digital filters and provides a reliable, yet very fast simulation system, which is assessed by means of a two degree-of-freedom motion platform, although the method might be applied to simulate other motion mechanisms.

    Test particle simulations of electron injection by the bursty bulk flows (BBFs) have been done using a test particle tracer code [1], and the output fields of the Lyon-Feddor-Mobarry global magnetohydro- dynamics (MHD) code[2]. The MHD code was run with high resolu- tion (oct resolution), and with specified solar wind conditions so as to reproduce the observed qualitative picture of the BBFs [3]. Test par- ticles were injected so that they interact with earthward propagating BBFs. The result of the simulation shows that electrons are pushed ahead of the BBFs and accelerated into the inner magnetosphere. Once electrons are in the inner magnetosphere they are further energized by drift resonance with the azimuthal electric field. In addition pitch angle scattering of electrons resulting in the violation conservation of the first adiabatic invariant has been observed. The violation of the first adiabatic invariant occurs as electrons cross a weak magnetic field region with a strong gradient of the field perturbed by the BBFs. References 1. Kress, B. T., Hudson,M.

    Label-free shotgun proteomics is routinely used to assess proteomes. However, extracting relevant information from the massive amounts of generated data remains difficult. This tutorial provides a strong foundation on analysis of quantitative proteomics data. We provide key statistical concepts that help researchers to design proteomics experiments and we showcase how to analyze quantitative proteomics data using our recent free and open-source R package MSqRob, which was developed to implement the peptide-level robust ridge regression method for relative protein quantification described by Goeminne et al. MSqRob can handle virtually any experimental proteomics design and outputs proteins ordered by statistical significance. Moreover, its graphical user interface and interactive diagnostic plots provide easy inspection and also detection of anomalies in the data and flaws in the data analysis, allowing deeper assessment of the validity of results and a critical review of the experimental design. Our tutorial discusses interactive preprocessing, data analysis and visualization of label-free MS-based quantitative proteomics experiments with simple and more complex designs. We provide well-documented scripts to run analyses in bash mode on GitHub, enabling the integration of MSqRob in automated pipelines on cluster environments (https://github.com/statOmics/MSqRob). The concepts outlined in this tutorial aid in designing better experiments and analyzing the resulting data more appropriately. The two case studies using the MSqRob graphical user interface will contribute to a wider adaptation of advanced peptide-based models, resulting in higher quality data analysis workflows and more reproducible results in the proteomics community. We also provide well-documented scripts for experienced users that aim at automating MSqRob on cluster environments. Copyright © 2017 Elsevier B.V. All rights reserved.

    Full Text Available OBJETIVOS: A videocirurgia com tecnologia robótica é um avanço médico e tecnológico recente, que tem no conceito de cirurgia-solo (sem auxiliares uma das aplicações práticas que podem permitir maior controle e precisão. Este estudo prospectivo foi desenhado para avaliar a curva de aprendizado da cirurgia-solo com o AESOP 3000 para colecistectomia laparoscópica, avaliando resultados e aplicações desta nova técnica. MÉTODO: Quinze pacientes foram submetidos à cirurgia vídeo-laparoscópica com auxílio de tecnologia robótica, utilizando a câmera com comando de voz AESOP 3000 e um braço mecânico fixo, permitindo a realização dos procedimentos sob o conceito de cirurgia-solo. A câmera posicionada no trocarte umbilical, foi ajustada para receber comando de voz através do transmissor HERMES, permitindo também a gravação de posições-chave. Um braço mecânico foi ligado à mesa cirúrgica para retração fixa de órgãos quando necessário. RESULTADOS: As cirurgias transcorreram sem anormalidades, sem necessidade de conversão, sendo necessária a retirada do AESOP para realização de câmera manual em um caso. O tempo operatório foi aumentado para permitir o tempo de ajuste do aparelho que foi, em média, de 21,9 min. Não foram documentadas complicações locais ou sistêmicas pós-operatórias. Quanto ao tempo de internação, a maioria dos pacientes recebeu alta em 24-48hs (86,7%. O grau de satisfação subjetiva da equipe com o auxiliar robótico foi de 3,94, em um máximo de 5,0. CONCLUSÕES: As potenciais vantagens do AESOP 3000 e dos sistemas de telecirurgia podem ser vislumbradas nesta avaliação inicial. A curva de aprendizado é simples e permitiu a realização das cirurgias por residentes em treinamento. Apesar de maior tempo operatório que o procedimento laparoscópico padrão, a assistência robótica mostrou maior precisão e estabilidade de câmera, sendo um passo inicial para a realização de

    In France, recent data on the consumption of psychoactive substances (PASs) among women entering prison are virtually nonexistent. The objective of this study was to describe the characteristics of female entrants at Montluc prison in Lyon (France) and to estimate their PAS consumption. Between June 1, 2004 and December 31, 2008, of 841 women entering the Lyon correctional facility, 535 had an entrance interview, conducted by a nurse, during which a questionnaire was systematically proposed; 306 detainees did not have this interview and could not be included in the study because of an immediate transfer to another prison or emergency hospitalization. Socioeconomic and incarceration characteristics, PAS consumption, as well as consumption level (occasional, regular, abusive or dependence) and psychological distress of the 535 interviewed detainees were systematically noted. This psychological distress was defined by the presence in the entrant talks or behavior suggesting clinical symptoms such as anxiety, depression, delusion, delirium, and mood or behavior disorders. Descriptive analysis was undertaken with the Chi(2) test and Fisher's exact test for differences between the proportions observed. The average age of the 534 responding detainees was 31.5 years; 59.2% had had no ongoing professional activity in the 12 months prior to incarceration, and 21.6% had already been imprisoned before; 37.5% of the entrants reported dependence on tobacco and 13.7% on alcohol; 6.6% reported regular, abusive use or dependence on cannabis, 20.4% on psychotropic medications, and 7.7% on other drugs (heroin, cocaine, synthetic drugs) in the 6 months preceding their incarceration; 39.2% of the consumers at risk reported using at least two substances; 7.1% of detainees were on opioid substitution treatment. A multiple correspondence factor analysis was used to note specific characteristics of three groups of PAS consumers. More frequent among young women detainees, overall PAS

    In prison, in 2012, according to various sources, from 4 to 56% of the European inmate population used psychoactive substances (PAS). The aim of our study was to describe PAS consumption during incarceration in the prison of Lyon-Corbas, France. A transversal descriptive study was conducted between September 23rd and September 27th 2013 among all inmates of this prison. We used an anonymous self-administered questionnaire, distributed at lunchtime and collected, the same day, at dinnertime, by the mental health service personnel. Among 785 inmates present at the time of the study in the prison of Lyon-Corbas, 710 were included and the response rate was 64.4% (95% CI [60.8-67.8]). Among 457 responding inmates, 16.4% (95% CI [13.2-20.0]) reported no PAS consumption. Among 382 consumers, 74.4% (95% CI [69.8-78.5]) used tobacco, 36.8% (95% CI [32.2-41.8]) cannabis, 30.4% (95% CI [25.9-35.1]) alcohol, 7.7% (95% CI [5.2-10.6]) heroin and 10.3% (95% CI [7.5-13.6]) cocaine. Furthermore, 15% of consumers had started PAS consumption during their incarceration. Among consumers of at least one PAS other than tobacco, cannabis and alcohol, the way of consumption was sniff for 60.0% (95% CI [48.5-70.2]) and injection for 31.0% (95% CI [21.6-42.1]). Use of several PAS at the same time and sharing sniffing and/or injection paraphernalia were other risky behaviors observed; 12% (95% CI [5.8-20.4]) of drug injectors declared using chlorine to sterilize their injection paraphernalia. Our study provides worrying data about PAS consumption in prison. The measures of prohibition do not prevent this consumption. There is even an initiation of consumption of PAS for 15% of the first-time incarcerated inmates. This finding should encourage public authorities to facilitate access of inmates to the care structures in prisons, to improve drug use prevention and care programs and to develop activities (sports, cultural, educational and vocational).

    The Internet of Things (IoT) has promised a future where everything gets connected. Unfortunately, building a single global ecosystem of Things that communicate with each other seamlessly is virtually impossible today. The reason is that the IoT is essentially a collection of isolated “Intranets of Things”, also referred to as “vertical silos”, which cannot easily and efficiently interact with each other. Smart cities are perhaps the most striking examples of this problem since they comprise a wide range of stakeholders and service providers who must work together, including urban planners, financial organisations, public and private service providers, telecommunication providers, industries, citizens, and so forth. Within this context, the contribution of this paper is threefold: (i) discuss business and technological implications as well as challenges of creating successful open innovation ecosystems, (ii) present the technological building blocks underlying an IoT ecosystem developed in the framework of the EU Horizon 2020 programme, (iii) present a smart city pilot (Heat Wave Mitigation in Métropole de Lyon) for which the proposed ecosystem significantly contributes to improving interoperability between a number of system components, and reducing regulatory barriers for joint service co-creation practices.

MEEREB members met for the third time in 2015 in France (Lyon to review the current rabies situation within the network and to discuss the way forward the prospect of a One Health approach against rabies. Dogs were the main vector of transmission in all MEEREB countries except for Croatia and Serbia where foxes represented the primary source. The number of rabies animal cases reported in 2014 varied substantially between countries with Ukraine reporting the highest number of animal cases. Human cases still occur in North Africa and all Middle East and Eurasian countries while no cases of human rabies were reported in Croatia, Serbia and Romania, although cases of rabies were identified in both dogs and foxes in 2014. Participants concluded that MEEREB can act as a think-tank where countries can share data, information, experiences and best practices to jointly address challenges in rabies control and prevention.

    Lyon comprehensive cancer center developed a home care-coordinating unit (HCCU) allowing a wide range of cancer care at home. We present the results of an organisational and strategical analysis of the unit, in relation with internal and external contexts. We describe the functioning of the unit, modelled from the daily follow-up of professionnels. Patient discharge is initiated by the oncologist at the inpatient clinic, at the day-hospital or at outpatient visit. After consent of the patient and relatives, the HCCU (nurses and medical oncologists) evaluates patient's needs, organises hospital discharge (contacts with community nurses and general practitioner, supply of medical appliances and drugs), and provides follow-up and counselling to patient and caregivers. The HCCU works in a challenging environment, with both partners and competitors. Within the hospital, it collaborates with all other units. Outside the hospital, partners are, besides patients themselves; general practitioners and community nurses home care agencies and network services, private medical appliance providers, and public health authorities. The unit might evolve towards formal home hospitalisation or community-hospital network. Collaboration of both structure closely associated with hospital could allow to provide continuous and graduated care by the same caregivers even if administrative structures change.

    The clinical significance of electrocardiogram in the assessment of patients with idiopathic dilated cardiomyopathy (IDCM) is currently unknown. The aim of this study was to determine the feasibility of recording serial changes in Sokolow-Lyon voltage (∆%QRS-voltage) in one year to estimate left ventricular reverse remodeling (LVRR) and predict a prognosis of IDCM patients under tailored medical therapy. Sixty-eight consecutive patients with mild symptoms (52.1 ± 13 years old; 69% men; NYHA I/II/III/IV; 33/29/6/0) underwent electrocardiography and echocardiography at baseline and 12 month follow-up (follow-up period: 3.9 years). LVRR was observed in 30 patients (44.1%). The ∆%QRS-voltage was significantly lower in the LVRR group (LVRR; -26.9%, non-LVRR: -9.2%, p voltage correlated with ∆%LV end-diastolic diameter (r = .634, p voltage group (voltage is associated with improvement in cardiac function and favorable prognosis in IDCM patients on medical therapy, suggesting that this index is a feasible marker for response to treatment of IDCM. © 2017 Wiley Periodicals, Inc.

Uma nova lei de controle adaptativa composta, que usa o erro de predição e os erros de seguimento para direcionar a estimação de parâmetros, é baseada na passividade e no método direto de Lyapunov. A convergência e a estabilidade global são mostradas para o algoritmo de controle adaptativo. O algoritmo tem as vantagens de não necessitar da “medição” de aceleração nas juntas e de não necessitar que a inversa da matriz de inércia estimada seja limitada. Exemplos de simulação são fornecidos para demonstrar o desempenho do algoritmo proposto

    Damage to petals may have varying effects on the reproductive success of the plant. The variation may depend on the kind of damage to the corolla. Whether the damage is limited to the corolla, as is usually the case with nectar-robbing perforations, or extending to the reproductive parts of the flower, as in the case of florivory holes, might determine the extent of the effect on the plant's reproduction. We examined the various perforations in the flowers of Arctostaphylos pungens and correlated their presence with fruiting success. We found that though florivory holes were highly associated with damage to reproductive parts, fruiting success did not differ significantly between flowers with the two kinds of damage. Although nectar-robbing perforations were not associated with reduced number of fruit produced, they were significantly correlated with reduced number of fruit that contained seemingly viable seeds. The implications of our findings are discussed in the context of pollination and antagonism.

    Full Text Available In the present paper, the effectiveness of the use of blinding agents, ionic exchanger resins and the combination of them in improving gold extraction from simulated preg-robbing ore is discussed. The blinding agents used were kerosene, diesel oil and pine oil, while the ion exchange resins used were Lewatit Monoplus MP 800, Lewatit AF 5 and guanidine. Preg-robbing conditions were simulated by blending fine activated carbon with ore sample. The investigation results show that the presence of artificial carbonaceous materials at 2% (w/w in the gold ore significantly reduces gold recovery. Pretreatment of artificial preg-robbing ore prior to cyanidation by mixing with kerosene, diesel oil and pine oil for 0.5h improved gold recovery up to 25.4%. A combination of pre-treatment using blinding agent and a resin in leach (RIL test using Lewatit MP 800 resin demonstrated a synergistic effect that improves gold recovery up to a level of 99.5%,which is significantly higher than using activated carbon and without pretreatment.

    Since 2016, an increase in the number of hepatitis A cases affecting mainly men who have sex with men (MSM) has been reported in low endemic countries in Europe. We calculated the attack rate in Lyon, France, in populations considered at high-risk: HIV-infected MSM and HIV-negative MSM receiving HIV pre-exposure prophylaxis (PrEP). In these populations, high level of immunity did not prevent the outbreak, indicating that vaccination should be reinforced, particularly in younger individuals.

    2017-09-01

    A new application (known as "VRF", or "Visual RobFit") for analysis of high-resolution gamma-ray spectra has been developed using non-linear fitting techniques to fit full-spectrum nuclide shapes. In contrast to conventional methods based on the results of an initial peak-search, the VRF analysis method forms, at each of many automated iterations, a spectrum-wide shape for each nuclide and, also at each iteration, it adjusts the activities of each nuclide, as well as user-enabled parameters of energy calibration, attenuation by up to three intervening or self-absorbing materials, peak width as a function of energy, full-energy peak efficiency, and coincidence summing until no better fit to the data can be obtained. This approach, which employs a new and significantly advanced underlying fitting engine especially adapted to nuclear spectra, allows identification of minor peaks that are masked by larger, overlapping peaks that would not otherwise be possible. The application and method are briefly described and two examples are presented.

    There is a lack of up-to-date data on sleep and dream habits of college students. To fill in this gap, we used an online questionnaire sent to the student mailing lists of two major universities of Lyon (Lyon 1 and Lyon 2) for the recruitment of an functional magnetic resonance imaging study with sleep disorders as exclusion criteria. In the sample (1,137 French college students, 411 males, mean age = 22.2 ± 2.4 years, body mass index = 22.0 ± 3.2 kg m -2 ), on average, the participants reported spending about 8 hr in bed during weekdays, 9 hr during the weekends, and 90.9% of them reported no difficulty falling asleep. Less than 0.4% of students reported to have sleep-walking episodes regularly, but nearly 7% reported regular sleep-talking episodes. The average dream recall frequency was about 3 mornings per week with a dream in mind. Dream recall frequency was positively correlated with the clarity of dream content and the frequency of lucid dreaming, and was negatively correlated with age. Fourteen percent of the students reported frequent lucid dreams, and 6% reported frequent recurrent dreams. We found a gender effect for several sleep and dream parameters, including dream recall frequency and time in bed, both of which were higher in women than in men. We have also observed differences between academic disciplines, namely humanities students (Lyon 2) reported spending more time in bed than sciences students (Lyon 1). These results confirm a gender difference for several sleep and dream parameters, and suggest a link between academic disciplines and sleep duration. © 2018 European Sleep Research Society.

    Full Text Available Helopeltis theivora Waterhouse, pest of tea, is emerging as a commonly occurring major pest of cashew (Anacardium occidentale L. in recent times. The field observation revealed Chromolaena odorata (L. R.M. King & H. Rob. weed support as an alternate host of this pest during off season of cashew. Biology of H. theivora on this weed was studied for the first time. The incubation period of eggs was 10.5 ± 1.2 d. The 1st, 2nd, 3rd, 4th and 5th nymphal instar developmental times were 36.11 ± 9.52, 43.29 ± 7.35, 27.15 ± 8.41, 41.31 ± 10.13, and 73.91 ± 5.67 h, respectively. Survival percentage of eggs was lower (60.53% than nymphal instars. Adult females and males lived for 22.6 ± 3.29 and 11.8 ± 1.64 d, respectively. Females showed dynamic patterns of fecundity with the number of eggs laid per female ranging 19 to 34. Longevity and fecundity of H. theivora on this weed were significantly lesser when compared on cashew. Egg parasitoids viz., Telenomus sp., Chaetostricha sp. and Erythmelus helopeltidis Gahan were recorded from H. theivora eggs on C. odorata for the first time. For better management decisions, it is important to know about this mirid biology, particularly their life cycle on their alternate hosts so that the right assessment can be made before taking up spray.

    Although previous studies show that robotic telescopes have the potential to enhance student learning, there is comparatively little research that focuses on teacher perceptions of this technology. This study investigates: "what is the academic merit of using SLOOH robotic telescopes to teach astronomy as perceived by science teachers?" Our sample consists of nine science teachers of students aged 13-18 years. Pre- and post-tests, interviews, and surveys were collected during two weeks of a summer online course about robotic telescopes. While pre and post-tests do not reveal a statistically significant gain in astronomy content knowledge, analysis of qualitative data reveals five themes which describe the most important aspects of using SLOOH according to participants: "Images," "Interface," "Classroom Application," "Instructor Impact," and "Logistical Issues." Analysis of these themes suggests that SLOOH can provide an interactive and social learning environment with capabilities to incorporate crossdisciplinary themes. Embora estudos anteriores mostram que os telescópios robóticos têm o potencial de melhorar a aprendizagem dos alunos, há relativamente pouca investigação focada nas percepções de professores a respeito desta tecnologia.

    Full Text Available The Robertsonian translocation (rob1; 29 is widely spread in commercial breeds and specially in genetic reserve of American Creole cattle. It is also described a delay on embryo development in front of normal ones. The action of 5–aza–C, as an hypomethylated agent, could permitted to decondensate the constitutive or facultative heterochromatin. In this work we made induction with the 5–aza–C(10mM, 2 hrs analogs, in lymphocyte cultures of female and male carriers and normal Creole cattle. The DNA hypometilation is found in the inactive X chromosome of late replication as it is incorporated during the last hours of cell culture. The decondensing effects of 5–aza–C analogs is observed in multiple regions of the autosomes chromatin, the rob1; 29 and the BTA1. A correlation between hypometilated regions and decondensed of facultative (conditional heterochromatin is related with genomic instability, and epigenetic reprogramming.La translocación Robertsoniana (rob1; 29 está ampliamente distribuida en razas comerciales y en reservas genéticas de bovinos Criollos americanos.

    Complex chromosome rearrangements (CCR) with two independent chromosome rearrangements are rare. Although CCRs lead to high unbalanced gamete rates, data on meiotic segregation in this context are scarce. A male patient was referred to our clinic as part of a family screening programme prompted by the observation of a 44,X,der(Y),t(Y;15)(q12;q10)pat,rob(13;14)(q10;q10)mat karyotype in his brother. Karyotyping identified the same CCR. Sperm FISH (with locus-specific probes for the segments involved in the translocations and nine chromosomes not involved in both rearrangements) was used to investigate the rearrangements meiotic segregation products and establish whether or not an inter-chromosomal effect was present. Sperm nuclear DNA fragmentation was also evaluated. For rob(13;14) and der(Y), the proportions of unbalanced products were, respectively, 26.4% and 60.6%. Overall, 70.3% of the meiotic segregation products were unbalanced. No evidence of an inter-chromosomal effect was found, and the sperm nuclear DNA fragmentation rate was similar to our laboratory's normal cut-off value. In view of previously published sperm FISH analyses of Robertsonian translocations (and even though the mechanism is still unknown), we hypothesise that cosegregation of der(Y) and rob(13;14) could modify rob(13;14) meiotic segregation. © 2013 Blackwell Verlag GmbH.

    Full Text Available Whether it is from the patient’s or the physical therapist’s point of view, FES cycling can be considered either as a recreational activity, or an engaging rehabilitation tool. In both cases, it keeps patients with lower-limb paralysis motivated to sustain a regular physical activity. Thus, it is not surprising that it was selected as one of the six disciplines of the first Cybathlon competition held on October 8, 2016. However, many unresolved issues prevent FES cycling from being an activity practiced outdoors on a daily basis; such as, low power production, rapid muscle fatigue, precise electrode positioning, lack of systematic procedures to determine stimulation patterns, and the difficulty of transferring disabled riders from their wheelchair to the tricycle. This article documents the challenges we faced during preparation for the Cybathlon 2016 FES cycling race, and provides results obtained during different phases of the process. A particular specificity of our team was that, unlike most other teams where pilots were mainly paraplegic, both the primary and backup pilots for team ENS de Lyon are C6/C7 tetraplegics, with neither voluntary control of their abdominal muscles nor hand grip, and only partial use of their arms.

    Full Text Available Process of deindustrialization of downtowns in most of well-developed Western European countries has been undertaken since 1960’s while in post-socialist countries just from last 25 years, after political and economic transitions in Central and Eastern Europe.  As far as urban structure is concerned, a new type of inner-city sites has appeared as a consequence of the collapse of industrial activities in second half of 20th century.  In vast majority of cases newly developed morhological units (e.g. run-down post-industrial have been unavailable to the public. As a reult, “classical” public space organization of European cities has been significantly changed. However, revitalization of post-industrial urban areas creates opportunities to reorganize public space according to current inhabitants and other urban space users’ needs. All transitions undertaken as a part of re-developement of brownfields sites are focused on impovements in physical and functional dimension of urban space quality to increase the standard of living condition. According to the concept of smat cities it is relaeted to “smart living” in sustainable urban environment. As a matter of fact, post-socialist cities in Central and Eastern Europe where interval of central planning was present in second half of 20th century and “classical” capitalist cites of Western Europe represent different patterns of public space transitions due to distinct historical development process of central space. In the paper a comparative study of Manchester, Lyon and Łódź is presented. The aim of the research is to indicate the reorganization of historically shaped public space structre in central space of analyzed cities after revitalization of post-industrial urban areas and new central space creation.

    The Lyon-Perrache gas works, built in 1834, presented the whole complexity of an industrial centre which was at the peak of technology. With 12 gas holders, there were as many underground structures, which very probably in were closed as they were when the plant was definitively stopped in 1954. During preliminary explorations on the site, the presence of hydrocarbons was detected in the ground, and the first tar containing vat was brought to light. BRGM and the ''Pollution Service'' Company helped EDF-GDF in this first operational phase. Two types of simultaneous actions were conducted: - Searching for information characterizing the site condition, -Application of actions for the treatment of waste matters in acceptable technical and economical conditions. They were conducted in three distinct steps. The first sept revealed the existence of 7 tanks, which were still susceptible to contain tar and to be at the origin of underground contamination. The second step was marked by the opening of tanks and by the technico-economical analysis of the principal solutions for removing the refuse they contained (rubbish, water, tar). In parallel, the diagnosis about the condition of the sub-soil and of the water table has shown distinct signs of pollution of soil and water by organic compounds (notably hydrocarbons and derivatives). Soil was specially affected at the place of former stockings of incineration residues (bitumen) and straight below the benzol removing unit. The third step, presently in progress, is aiming at a better definition of underground quality around two singular points, in order to define and test the best adapted treatment method. The aims of the future step shall be to reclaim a level of general quality compatible with the future utilization of soil and sub-soil. (author). 4 figs., 5 photos

    Purpose: To investigate, in rectal cancer, the benefit of a neoadjuvant radiation dose escalation with endocavitary contact radiotherapy (CXRT) in addition to external beam radiotherapy (EBRT). This article provides an update of the Lyon R96-02 Phase III trial. Methods and Materials: A total of 88 patients with T2 to T3 carcinoma of the lower rectum were randomly assigned to neoadjuvant EBRT 39 Gy in 13 fractions (43 patients) vs. the same EBRT with CXRT boost, 85 Gy in three fractions (45 patients). Median follow-up was 132 months. Results: The 10-year cumulated rate of permanent colostomy (CRPC) was 63% in the EBRT group vs. 29% in the EBRT+CXRT group (p < 0.001). The 10-year rate of local recurrence was 15% vs. 10% (p = 0.69); 10-year disease-free survival was 54% vs. 53% (p = 0.99); and 10-year overall survival was 56% vs. 55% (p = 0.85). Data of clinical response (CR) were available for 78 patients (36 in the EBRT group and 42 in the EBRT+CXRT group): 12 patients were in complete CR (1 patient vs. 11 patients), 53 patients had a CR {>=}50% (24 patients vs. 29 patients), and 13 patients had a CR <50% (11 patients vs. 2 patients) (p < 0.001). Of the 65 patients with CR {>=}50%, 9 had an organ preservation procedure (meaning no rectal resection) taking advantage of major CR. The 10-year CRPC was 17% for patients with complete CR, 42% for patients with CR {>=}50%, and 77% for patients with CR <50% (p = 0.014). Conclusion: In cancer of the lower rectum, CXRT increases the complete CR, turning in a significantly higher rate of long-term permanent sphincter and organ preservation.

    Lipofilling is now performed to improve the breast contour, after both breast-conserving surgery and breast reconstruction. However, injection of fat into a previous tumor site may create a new environment for cancer and adjacent cells. There is also no international agreement regarding lipofilling after breast cancer treatment. The authors included three institutions specializing in both breast cancer treatment and breast reconstruction (European Institute of Oncology, Milan, Italy; Paris Breast Center, Paris, France; and Leon Berard Centre, Lyon, France) for a multicenter study. A collective chart review of all lipofilling procedures after breast cancer treatment was performed. From 2000 to 2010, the authors reviewed 646 lipofilling procedures from 513 patients. There were 370 mastectomy patients and 143 breast-conserving surgery patients. There were 405 patients (78.9 percent) with invasive carcinoma and 108 (21.1 percent) with carcinoma in situ. The average interval between oncologic surgical interventions and lipofilling was 39.7 months. Average follow-up after lipofilling was 19.2 months. The authors observed a complication rate of 2.8 percent (liponecrosis, 2.0 percent). Twelve radiologic images appeared after lipofilling in 119 breast-conserving surgery cases (10.1 percent). The overall oncologic event rate was 5.6 percent (3.6 percent per year). The locoregional event rate was 2.4 percent (1.5 percent per year). Lipofilling after breast cancer treatment leads to a low complication rate and does not affect radiologic follow-up after breast-conserving surgery. A prospective clinical registry including high-volume multicenter data with a long follow-up is warranted to demonstrate the oncologic safety. Until then, lipofilling should be performed in experienced hands, and a cautious oncologic follow-up protocol is advised. Therapeutic, IV [corrected].

    To evaluate irradiation effects on functional signs and choroidal neo-vascular lesions in age-related macular degeneration (AMD) that does not respond to laser therapy. Since 1994, 250 consecutive AMD patients were treated by two radiotherapy teams for sub-foveal neo-vascular lesions. At the end of september 1996, 52 patients were evaluable with a 1-year follow-up. Group 1 (Department de Radiotherapie Oncologie, Centre Hospitalo-Universitaire Lyon Sud) included 26 patients who were treated with a lateral beam of 6 MV photons. The irradiation dose were 20 Gy in five fractions for small lesions and 28.8 Gy in eight fractions for larger lesions. Group 2 (Centre Oncologie Radiotherapie Saint-Jean) was composed of 26 patients treated with a mini-beam of 25 MV photons via lateral arc-therapy. Beam diameters (14 and 18 mm) were adapted to the lesion size. The total dose was 16 Gy in four fractions or 20 Gy in five fractions. Functional and anatomical results were assessed at 3, 6, 9 months and 1 year after radiation therapy. Stable visual acuity was observed in 44 % (23/52) of the patients and visual acuity was improved in 35 % (18/52) of the patients at 6 months. Good functional results reached 79 % (41/52) at 6 months and 74 % (17/23) at 12 months. There was no statistical difference between the two groups and dose levels. All severe complications (1 cataract, 3 dilated choroidal vessels, and 2 papillitis) occurred in group 1. Though it is too early to conclude on the best dose level, radiotherapy of sub-foveal neo-vascular lesions of AMD that cannot be treated via laser therapy provides encouraging results. The technique used must be very precise to adequately irradiate the fovea and spare surrounding sensitive areas. Further studies and trials involving patients' randomization are necessary to confirm these preliminary results. (author)

    Full Text Available A current trend in the agricultural area is the development of mobile robots and autonomous vehicles for remote sensing. One of the major challenges in the design of these robots is the development of the electronic architecture for the integration and control of the devices. Recent applications of mobile robots have used distributed architectures based on communication networks. A technology that has been widely used as an embedded network is the CAN protocol. The implementation of the ISO11783 standard represents the standardization of the CAN for application in agricultural machinery. This work describes the design and implementation of an electronic architecture for a mobile agricultural robot. The discussions are focused on the developed architecture, the wireless communication system for teleoperation and the distributed control based on CAN protocol and ISO11783. The evaluation of the developed system was based on the analysis of performance parameters such as motor response and architectural time delay obtained with the robot operation. The results show that the developed architecture can be applied for teleoperation and distributed control of agricultural robots meeting the requirements for accurate robot movement and an acceptable response time for robot control commands and supervision.Uma tendência atual na área agrícola é o desenvolvimento de robôs móveis e veículos autônomos para sensoriamento remoto. Um dos grandes desafios no projeto desses robôs é o desenvolvimento da arquitetura eletrônica para integração e controle dos dispositivos.

    Full Text Available Resumen: En este trabajo se presenta un nuevo prototipo de plataforma robótica cooperativa, destinada a la asistencia en intervenciones quirúrgicas de fijación transpedicular lumbar. El uso de sistemas robóticos de asistencia durante la ejecución de procedimientos quirúrgicos convencionales contribuye a la mejora en los resultados de las intervenciones al permitir elevados niveles de precisión y seguridad. Por ello, resulta crucial garantizar la robustez y destreza de los dispositivos empleados, incluso en las proximidades de configuraciones que pudieran introducir inestabilidades en su funcionamiento. Partiendo de esta idea, se ha implementado una estrategia de gestión de singularidades en la plataforma robótica, basada en el uso de un algoritmo de mínimos cuadrados amortiguados con factor de amortiguamiento adaptativo, unido a un método para la optimización de la configuración articular del manipulador redundante empleado, Mitsubishi PA10–7C. Abstract: In this research work, a new prototype of collaborative robot- assisted surgical platform for transpedicular fixation surgeries is presented. The usage of assistive robotic systems during conventional surgical procedures improves surgical outcomes, as they ensure high levels of precision and safety. Hence, robustness and dexterity of the mechatronic devices must be guaranteed, even in the neighborhood of unstable configurations during their performance. Bearing this in mind, a singularity management strategy has been implemented in the robotic platform, based on the Damped Least Squares method using an adaptive damping factor together with a methodology for optimization of joint redundancy of the platform manipulator, Mitsubishi PA10-7C.

    Chromolaena odorata (L.) R.M. King & H. Rob. (Asteraceae) is a scrambling perennial shrub that originated in the Americas, but is now common in sub-Saharan Africa, Asia and Oceania, where it has become a serious weed. The species, particularly the biotype found in Asia and West Africa, has many ethnopharmacological uses, including treatment of malaria, wounds, diarrhoea, skin infection, toothache, dysentery, stomach ache, sore throat, convulsions, piles, coughs and colds. Furthermore, no attempt has been made to synthesise and review the available literature on the usefulness of the plant in the sub-Saharan African region, hence this paper examines the beneficial attributes of C. odorata in sub-Saharan Africa. Published information on the species was gathered by the use of different database platforms, including Google Scholar, ScienceDirect, SciFinder and Scopus. Records indicate that two biotypes of C. odorata are present in sub-Saharan Africa viz. the more widespread Asian/West African C. odorata biotype (AWAB) and the southern African biotype (SAB). While the usefulness of the former is well elucidated in the literature, such information on the latter is still scarce. Although the importance of AWAB C. odorata as a fallow species and as a soil fertility improvement plant in the slash and burn rotation system of agriculture in West Africa is increasingly being recognised, its usage in traditional medicinal practice is far more appreciated. The species has a wide range of ethnopharmacological uses, possibly because of the presence of flavonoids, essential oils, phenolics, tannins and saponins. The plant is reported to have antibacterial, anti-inflammatory, antioxidant, anthelminthic, antifungal, cytotoxic, anticonvulsant, antiprotozoal, antispasmodic, antipyretic and analgesic properties. While the results of this review suggest that the AWAB plant can be exploited as an alternative to other threatened plant species known to possess similar medicinal potential

    Full Text Available L’Écosse des Lumières, récemment rattachée à sa puissante voisine anglaise par l’Acte d’Union de 1707, connaît une crise identitaire qui l’amène à une redéfinition de son image. Sa représentation, tant tangible, physique que mentale, nationale, passe par une réécriture de son Histoire par le mythe, ce récit imaginaire populaire ou littéraire mettant en scène des êtres surhumains et des actions remarquables qui est, selon Roland Barthes, « un discours, un système de communication, un message » (Mythologies. Ce message d’une re-construction identitaire est transmis par Walter Scott dans ses romans écossais, en particulier Waverley et Rob Roy qui dépeignent l’Écosse et ses habitants à travers les yeux naïfs d’érudits anglais. Ce portrait textuel, loin d’être un tableau réaliste, est brossé à l’aide d’une superposition d’images mythiques et littéraires, notamment dans la description des paysages des Highlands. De plus, les personnages, tel le héros populaire historique et hors-la-loi écossais Rob Roy, sont transformés, romancés, mythifiés dans ces fictions qui retracent, sous forme d’épopée, les grandes révoltes jacobites de 1715 et 1745. Enfin, le langage pictural et imagé contribue à véhiculer une vision mythique de l’Écosse. Nous chercherons donc à comprendre et à expliquer les motivations et les répercussions de ce maillage d’images fictives connues, tirées de mythes ou d’ouvrages littéraires, et tissées au moyen d’images rhétoriques au texte scottien pour créer nouveau visage écossais.Recently united to its powerful English twin sister through the 1707 Union Act, Scotland experiences a major identity crisis in the Enlightenment. Politically, religiously, and socially divided, it is led to redefine its image by rewriting history through mythology. A myth is “a speech, a system of communication, a message”, Roland Barthes explains in Mythologies. This message

    Theoretical calculations have been performed to predict the antioxidant property of phenolic compounds extracted from Artocarpus altilis. The Osbnd H bond dissociation enthalpy (BDE), ionization energy (IE), and proton dissociation enthalpy (PDE) of the phenolic compounds have been computed. The ONIOM(ROB3LYP/6-311++G(2df,2p):PM6) method is able to provide reliable evaluation for the BDE(Osbnd H) in phenolic compounds. An important property of antioxidants is determined via the BDE(Osbnd H) of those compounds extracted from A. altilis. Based on the BDE(Osbnd H), compound 12 is considered as a potential antioxidant with the estimated BDE value of 77.3 kcal/mol in the gas phase.

    Full Text Available Graças ao melhor conhecimento da anatomia segmentar do fígado e desenvolvimento de novas técnicas, houve aumento no número de indicações de hepatectomias. O desenvolvimento da cirurgia minimamente invasiva ocorreu paralelamente e o aumento da experiência, aliado ao desenvolvimento de novos instrumentais, resultaram no crescimento exponencial das ressecções hepáticas videolaparoscópicas. A abordagem laparoscópica pode tornar viável a ressecção hepática em pacientes cirróticos com hipertensão portal que não tolerariam este mesmo procedimento por via laparotômica. A cirurgia robótica surgiu nos últimos anos como a última fronteira de desenvolvimento técnico aplicado à videocirurgia. O presente trabalho descreve a experiência pioneira de ressecção hepática totalmente com o uso de robótica na América Latina, em paciente com carcinoma hepatocelular e cirrose hepática. A hepatectomia laparoscópica com o uso do sistema robótico Da Vinci permite refinamentos técnicos graças à visualização tridimensional do campo cirúrgico e utilização de instrumentais precisos e com grande amplitude de movimentação que simulam os movimentos da mão humana.The surgical robotic system is superior to traditional laparoscopy in regards to 3-dimensional images and better instrumentations. Robotic surgery for hepatic resection has not yet been extensively reported. The aim of this paper is to report the first known case of liver resection with use of a computer-assisted, or robotic, surgical device in Latin America. A 72-year-old male with cryptogenic liver cirrhosis and hepatocellular carcinoma was referred for surgical treatment. Preoperative clinical evaluation and laboratory data disclosed a Child-Pugh class A patient. Magnetic resonance imaging showed a 2.2 cm tumor in segment 5. Liver size was decreased and there were signs of portal hypertension, such as splenomegaly and enlarged portal vein collaterals. Preoperative upper

    Full Text Available Resumo Os sistemas comerciais destinados à automação da soldagem orbital enfrentam desafios perante o controle da trajetória e a parametrização do processo. Os tubos e dutos do setor de Petróleo e Gás apresentam descontinuidades, advindas de sua fabricação, críticas para o processo de soldagem. Para superar isto, o presente trabalho investiga a utilização de sensores para correção em tempo real da soldagem orbital. Um robô antropomórfico atua na condução da tocha. Um sensor a arco para seguimento de junta e um sensor baseado no contato elétrico para procura da junta foram empregados. Um programa em forma de algoritmos para geração de uma trajetória orbital automática e alocação dos parâmetros de soldagem foi desenvolvido. A validação da estratégia proposta e do controle da tocha pelo sensor a arco foi realizada com depósitos em corpos de prova de tubos. A soldagem do passe de raiz com um processo MIG/MAG com controle de corrente no curto-circuito também foi executada em conjunto com o sensor a arco.

    Purpose: The Lyon R90-01 randomized trial investigated whether the interval between preoperative radiation therapy and surgery influenced rectal cancer outcome. Long-term results are reported here after a median follow-up of 17 years. Methods and Materials: Between February 1991 and December 1995, 210 patients from 29 French centers were randomly assigned (ratio of 1:1) to groups that waited either 2 weeks (short interval [SI]) or 6 to 8 weeks (long interval [LI]) between neoadjuvant radiation therapy and surgery. The primary endpoint was sphincter-preserving surgery. Results: LI group showed a better pathologic response (complete response or few residual cells) after radiation therapy than the SI group (26% vs 10.3%, P=.015). A better pathologic response was associated in multivariate analysis with significant improvement of overall survival (pT: P=.0293 and pN: P=.0048) but it was irrespective of the interval duration. The median follow-up was 17.2 years. The 5-, 10-, 15-, and 17-year overall survival rates were, respectively, 66.8%, 48.7%, 40.0%, and 34.0% for the SI group and, respectively, 67.1%, 53.5%, 41.9%, and 34.0% for the LI group. There were no significant differences between groups in terms of survival (P=.7656) or local recurrence rates (SI: 14.4% vs LI: 12.1%, respectively; P=.6202). Of 24 local disease recurrences, 20 (83%) occurred during the first 2 postoperative years, and all but one (96%) occurred during the first 5 postoperative years. The rate of second new malignancies was 9.4% (19 patients). Conclusions: The radiation-induced sterilization rate of the preoperative cancer specimen was a marker of good prognosis. The interval duration (the treatment being the same) although it is modifying the sterilization rate has no impact on survival. Radiation therapy did not postpone local recurrence, because the rate of local relapse after 5 years was low. Radiation-induced cancers after radiation therapy were unusual and should not influence

Por ello, a la robótica manipuladora se la considera una disciplina decisiva en el sector industrial. Además, en un futuro no muy lejano los robots manipuladores pasarán a ser también esenciales en la vida cotidiana de la sociedad. Así, existe una demanda creciente de aplicaciones con robots manipuladores con requisitos software como son la reutilización, flexibilidad y adaptabilidad. Lamentablemente, en la actualidad hay una falta de estandarización de plataformas hardware y software, por lo que es extremadamente complicado satisfacer estos requisitos. Así, se contempla, por lo tanto, una necesidad de definir una metodología que proporcione unas pautas y guíe en el diseño, implementación y en la ejecución de sistemas software para este tipo de aplicaciones. Este trabajo explora las ventajas proporcionadas por la Ingeniería Dirigida por Modelos (MDE- Model Driven Engineering en el diseño y desarrollo de tareas realizadas por robots manipuladores.

    Phenology plays a key role in the environment and ecosystem. Primary and secondary students around the world have been collecting vegetation phenology data and contributing to ongoing scientific investigations. They have increased research capacity by increasing spatial coverage of ground observations that can be useful for validation of remotely sensed data. The green-up and green-down phenology measurement protocols developed at the University of Alaska Fairbanks (UAF) as part of the Global Learning and Observations to Benefit the Environment (GLOBE) program, have been used in more than 250 schools in over 20 countries. In addition to contributing their data, students have conducted their own investigations and presented them at science fairs and symposiums, and international conferences. An elementary school student in Alaska conducted a comprehensive study on the green-down rates of native and introduced trees and shrubs. Her project earned her a one-year college scholarship at UAF. Students from the Model Secondary School for the Deaf in Washington, D. C. and from the Indiana School for the Deaf collaborated on a comparative green-up study, and were chosen to present at an international conference where students from more than 20 countries participated. Similarly, students in Thailand presented at national conferences, their studies such as "The Relationship between Environmental Conditions and Green-down of Teak Trees (Tectona grandis L.)" at Roong Aroon School, Bangkok and "The Comparison of Budburst and Green-up of Leab Trees (Ficus infectoria Roxb.) at Rob Wiang and Mae Khao Tom Sub-district in Chiang Rai Province". Some challenges in engaging students in phenological studies include the mismatch in timing of the start and end of the plant growing season with that of the school year in northern latitudes and the need for scientists and teachers to work with students to ensure accurate measurements. However these are outweighed by benefits to the scientists

    Full Text Available INTRODUCCIÓN: los procedimientos de cirugía cardiotorácica mínimamente invasiva (MICS, su sigla en Inglés buscan reducir las complicaciones de las grandes disecciones. No obstante, ante la falta de contacto directo con el tejido por parte del cirujano, éste recibe una sensación parcial de tacto y fuerza, lo que puede originar errores de procedimiento, inadecuada fuerza aplicada al tejido y fatiga durante el acto quirúrgico. La inclusión de dispositivos robóticos con la técnica MICS ha potencializado las habilidades del cirujano para la manipulación de los tejidos, y aunque los desarrollos del mercado no cuentan aún con retroalimentación táctil, se trabaja en prototipos robóticos que incorporan realimentación de fuerza y torque. OBJETIVO: proponer las condiciones y restricciones relacionadas con la incorporación de realimentación de fuerza y torque en MICS robótica, aplicables a diferentes configuraciones de manipuladores, y analizar la implementación de dichas condiciones en un simulador quirúrgico. MATERIAL Y MÉTODOS: partiendo del análisis de necesidades durante procedimientos cardiotorácicos y las condiciones de cirugía mínimamente invasiva, se identificaron los requerimientos para garantizar reflexión de fuerza y se realizó un análisis matemático de dichas consideraciones. Finalmente, se verificaron los análisis matemáticos mediante técnicas de modelización y simulación utilizando la plataforma computacional Matlab®. RESULTADOS: se argumentaron tres tipos de consideraciones: a Cinemático: la existencia de un punto fijo, las formas de garantizarlo durante procedimientos MICS robóticos, y las trayectorias de movimiento que el manipulador sigue en aplicaciones de cirugía cardiotorácica; b Dinámico: la repercusión de fuerzas externas en el manipulador y la manera de considerarlas en el desarrollo de controladores que permitan al cirujano percibir una sensación de contacto con el tejido; c Sensorial

    After a brief presentation of the strengths and peculiarities of Greenlys, a demonstrator of a global urban smart electric power system which has been experimented in Lyons and Grenoble, this report identifies and outlines the evolutions associated with this project which introduces a true change in energy models. It outlines the characteristics of smart grids and the fact that the French and European contexts promote their development which induces flexibility, economic growth, and the emergence of new economic models and regulations. The next part presents Greenlys, the involved partners, its innovating objectives, some characteristics of the implementation sites (two metropolitan areas), its specific innovations, its various associated equipment. It describes how the user or consumer becomes an actor in terms of active demand and consumption management, indicates sociological user profiles which have been identified during this experiment, and also indicates and comments tested solutions with their functionalities and returns on experience. The next chapters comment the contributions to regulation evolutions related to cut-off and business model, outline the benefit in the office building sector, and the positive influence of these grid innovations on energy transition, discuss the value of a smart power system in urban areas, and finally outline the role of the various partners which are representative of the French electric power system, and the support of public investments managed by the ADEME

    To evaluate irradiation effects on functional signs and choroidal neo-vascular lesions in age-related macular degeneration (AMD) that does not respond to laser therapy. Since 1994, 250 consecutive AMD patients were treated by two radiotherapy teams for sub-foveal neo-vascular lesions. At the end of september 1996, 52 patients were evaluable with a 1-year follow-up. Group 1 (Department de Radiotherapie Oncologie, Centre Hospitalo-Universitaire Lyon Sud) included 26 patients who were treated with a lateral beam of 6 MV photons. The irradiation dose were 20 Gy in five fractions for small lesions and 28.8 Gy in eight fractions for larger lesions. Group 2 (Centre Oncologie Radiotherapie Saint-Jean) was composed of 26 patients treated with a mini-beam of 25 MV photons via lateral arc-therapy. Beam diameters (14 and 18 mm) were adapted to the lesion size. The total dose was 16 Gy in four fractions or 20 Gy in five fractions. Functional and anatomical results were assessed at 3, 6, 9 months and 1 year after radiation therapy. Stable visual acuity was observed in 44 % (23/52) of the patients and visual acuity was improved in 35 % (18/52) of the patients at 6 months. Good functional results reached 79 % (41/52) at 6 months and 74 % (17/23) at 12 months. There was no statistical difference between the two groups and dose levels. All severe complications (1 cataract, 3 dilated choroidal vessels, and 2 papillitis) occurred in group 1. Though it is too early to conclude on the best dose level, radiotherapy of sub-foveal neo-vascular lesions of AMD that cannot be treated via laser therapy provides encouraging results. The technique used must be very precise to adequately irradiate the fovea and spare surrounding sensitive areas. Further studies and trials involving patients` randomization are necessary to confirm these preliminary results. (author) 13 refs.

    Full Text Available Incriminated for negative externalities such as both local and global pollution, noise, sealing extension or public space high consumption, private cars have been perceived as a factor of un-sustainable mobility since the early 80’s by urban planners and designers. In the new paradigm of the so-called “sustainable city” urban planners and designers target now a modification of social behaviour and particularly social mobility practices. The production of transport alternatives and restrictions to automobiles in city centres through car-parking limitations and fare systems as developed in urban mobility plans (Plans de Déplacements Urbains are unfortunately too weak to generate a modal shift ripple-effect in French cities. Considering the last issue of the French national institute of statistics and economic studies’ survey (Hubert, 2009 the modal-share in favour of car-transit remains the same for the period of time between 1994 and 2008 for the biggest French cities, in spite of steady efforts for the development of public transportation alternatives such as the diffusion of the tramway’s comeback (from Grenoble 1986, to Dijon 2013. According to a series of relatively recent research papers (Kaufmann, 2002 ; Lefevre & Offner, 1990 focused on the “economically irrational” behaviour of the majority of private-car drivers concerning the question of modal shift, a research framework has been developed.

This approach of identifying this disconnect between rationalities in planning and rationalities in social practices in the urban mobility context is aimed to extend to the complex perception of urban environments by car-drivers, to identify new targets of modal-split policies to be structured as new action-levers. This perception will deal with several issues orchestrated through urban design projects such as public spaces, physical distances or parking constraints. The second main issue of this conceptual framework deals with rationalities of user’s mobility practices. The axiological rationality (Boudon, 1995 seems to be heuristic to question values and practices, searching for the rationale behind the conclusions that users draw when making mobility decisions (for example “the car is faster in my situation”. This justification process needs to be finely analyzed in combination with several concepts, norms and values that “make sense” for the individual. We propose the hypothesis that the combination of perception biases and axiological rationalities could helps to explain behaviors defined as “irrational” for urban mobility planners and to delineate the major levers of social acceptation and adoption of so-called sustainable urban environments.

    Full Text Available Polímeros expandidos são bastante competitivos para serem utilizados como materiais de flutuabilidade, devido a sua baixa densidade. Em particular, eles se apresentam muito eficientes no desenvolvimento de módulos de flutuabilidade de robôs submarinos do tipo ROV (Remote Operated Vehicle. Este trabalho descreve um estudo da absorção de água em dois diferentes tipos de polímeros expandidos (poliuretano e poliestireno expandido, em diferentes meios aquosos (água do mar e água destilada. Estudo sobre o efeito da geometria das amostras com relação à cinética de absorção de água demonstrou que as amostras com maior área de contato com a água se apresentam mais susceptíveis à absorção de água. Os estudos também revelaram que o poliuretano expandido sofreu uma importante perda de material devido ao seu manuseio durante os ensaios de absorção. A influência do meio aquoso foi também bastante notável para este material, no qual apresentou uma maior taxa de absorção nos ensaios com água destilada em comparação com os ensaios utilizando água do mar. Os resultados das análises demonstraram que o melhor material para ser utilizado como módulo de flutuabilidade do robô submarino é o poliestireno expandido, pois este material não apresentou uma notável degradação e perda de material durante os ensaios de absorção.Owing to the low density and relative low price, expanded polymers appear to be competitive for buoyancy systems. Expanded polymers are particularly efficient to develop buoyancy modules of submarine robots such as ROV (Remote Operated Vehicle.

    Full Text Available En el món ràpidament canviant d’avui en dia cada cop és més evident que l’èxit no està només basat en què sabem o quant sabem, sinó en la nostra habilitat per pensar i actuar de manera creativa. Malauradament, en la majoria dels casos els models d’aprenentatge tradicionals de les escoles no solen estar enfocats a desenvolupar el pensament creatiu. Aquest problema s’accentua encara més als països en vies de desenvolupament, on la creativitat ben utilitzada podria convertir-se en una eina fonamental per reduir la pobresa i en un motor important per al desenvolupament humà sostenible. Aquest article descriu un projecte pilot finançat per la Universitat de Girona, que combina innovació educativa i cooperació al desenvolupament, i que s’ha dut a terme a Shanti Bhavan, una escola rural del sud de l’Índia. El projecte, basat en la teoria del construccionisme, ha consistit en uns tallers en els quals, a través de les tecnologies de la informació i la comunicació (concretament treballant la robòtica i la intel•ligència artificial, s’ha estimulat la creativitat i l’esperit crític dels nens. A més, simultàniament i a través del joc i l’exploració, s’ha fet un reforç no formal de les assignatures que plantegen més problemes a l’Índia rural. L’objectiu a llarg termini és que aquests nens esdevinguin agents del canvi, creatius i innovadors, de les seves pròpies comunitats, i que, compromesos amb la seva realitat social, siguin capaços de proposar noves alternatives per millorar la seva qualitat de vida i engeguin projectes per crear riquesa en els diferents àmbits socials.

    Chinese international students have become an increasingly visible presence around the globe, and interest in these students has consequently increased among universities, researchers, and policy-makers, who often see international students as a source of increased soft power. This article...... questions the idea of Chinese international students as a soft-power tool. This is done through a critical discussion of the concept of soft power and the rather limited research on educational diplomacy, demonstrating that the analytical vagueness of the concept of soft power leads to an oversimplified...... understanding of the linkage between international students and soft power. In order to provide a more nuanced understanding of this linkage, the article examines the actual overseas experience of Chinese international students and argues that the linkage between international students and soft power is highly...

    Floral displays are under selection to both attract pollinators and deter antagonists. Here we show that a common floral trait, a nectar guide pattern, alters the behavior of bees that can act opportunistically as both pollinators and as antagonists. Generally, bees access nectar via the floral limb, transporting pollen through contact with the plant's reproductive structures; however bees sometimes extract nectar from a hole in the side of the flower that they or other floral visitors create...

    Full Text Available Pekalongan City located in the coastal area which vulnerable to the tidal flood. The tidal flood in Pekalongan City always increases. The tidal flood inundating the North Pekalongan Sub-district to the radius of three kilometers from the beach. There were eight villages which stagnated by the tidal flood, include the Village Pabean and Village Bandengan. The adaptive capacity of society needs to be improved to deal with the tidal flood. This study aims to assess the adaptive capacity of coastal communities Pekalongan against the tidal flood vulnerability by using the quantitative methods with scoring and descriptive statistical analysis to synthesize the results of the analysis. Adaptive capacity assessed at the level of individuals, communities and cities. This analysis also based on the physical, social and economic aspects. The result of the analysis showed that at the individual level, both of these villages, the level of the adaptive community was low. It was caused by the low ability of communities to repair houses. This level of adaptive capacity was also influenced by the level of education and income levels. At the community level, the level of adaptive capacity was determined by the ability of communities to improve infrastructure. This level of adaptive capacity was also determined by the existence of the organization and the ability to raise funds. It could be known that the level of adaptive capacity at the community level was moderate. At the city level, the government was able to adapt by providing technological and institutional. Society needs to increase the adaptive capacity by improving the ability of the economy, in addition, to optimizing the performance of government and non-government organizations.

  9. Students developing resources for students.

    The development of new technologies has provided medical education with the ability to enhance the student learning experience and meet the needs of changing curricula. Students quickly adapt to using multimedia learning resources, but these need to be well designed, learner-centred and interactive for students to become significantly engaged. One way to ensure that students become committed users and that resources become distinct elements of the learning cycle is to involve students in resource design and production. Such an approach enables resources to accommodate student needs and preferences, but also provides opportunities for them to develop their own teaching and training skills. The aim of the medical student research project was to design and produce an electronic resource that was focused on a particular anatomical region. The views of other medical students were used to decide what features were suitable for inclusion and the resulting package contained basic principles and clinical relevance, and used a variety of approaches such as images of cadaveric material, living anatomy movies and quizzes. The completed package was assessed using a survey matrix and found to compare well with commercially available products. Given the ever-diversifying arena of multimedia instruction and the ability of students to be fully conversant with technology, this project demonstrates that students are ideal participants and creators of multimedia resources. It is hoped that such an approach will help to further develop the skill base of students, but will also provide an avenue of developing packages that are student user friendly, and that are focused towards particular curricula requirements. © Blackwell Publishing Ltd 2012.

    Imaging and its optimal use are imperative to the practice of medicine, yet many students don't receive a formal education in radiology. Concurrently, students look for ways to take time away from medical school for residency interviewing. Web-based instruction provides an opportunity to combine these imperatives using online modalities. A largely Web-based course in radiology during the 4th year of medical school was evaluated both for its acceptance to students who needed to be away from campus for interviews, and its effectiveness on a nationally administered standardized test. All students were placed into a structured program utilizing online videos, online modules, online textbook assignments, and live interactive online lectures. Over half of the course could be completed away from campus. The Alliance of Medical Student Educators in Radiology test exam bank was used as a final exam to evaluate medical knowledge. Positive student feedback included the freedom to travel for interviews, hands-on ultrasound training, interactive teaching sessions, and quality Web-based learning modules. Negative feedback included taking quizzes in-person, a perceived outdated online textbook, and physically shadowing hospital technicians. Most students elected to take the course during the interview months of October through January. The Alliance of Medical Student Educators in Radiology final exam results (70.5%) were not significantly different than the national cohort (70%) who took the course in-person. Test scores from students taking the course during interview travel months were not significantly different from students who took the course before (P=.30) or after (P=.34) the interview season. Students desire to learn radiology and often choose to do so when they need to be away from campus during the fall of their 4th year of study to accomplish their residency interviews. Web-based education in radiology allows students' interview traveling and radiology course

Some of the participants on the trip to Chamonix enjoy the breath-taking scenery.For many young people, their time at CERN can be filled not only with exciting opportunities but also anxious uncertainty. Whether your stay is for just a few months or a few years, it can be quite daunting to arrive at a new place and try to find your way around – and let’s face it, CERN is not an easy place to find your way around! Much of their time here is spent on doing analysis or technical work on the experiments or the LHC; but even at the end of the day or on weekends there are few social outlets at CERN geared just towards young people.

The authors examined all abstracts resulting from this search and reviewed the full text of the relevant articles as well as additional articles identified in the reference lists of the relevant articles. Studies were classified by year of student (preclinical or clinical and study design (controlled or non-controlled.Results: A total of 67 articles met the final search criteria and were fully reviewed. Most studies were non-controlled and performed in the clinical years. Although the studies were quite variable in quality, design, and outcomes, in general video recording of performance and subsequent review by students with expert feedback had positive outcomes in improving feedback and ultimate performance. Video review with self-assessment alone was not found to be generally effective, but when linked with expert feedback it was superior to traditional feedback alone.Conclusion: There are many methods for integrating effective use of video-captured performance into a program of learning. We recommend combining student self-assessment with feedback

    Full Text Available The perceived contribution of science education online course to pre-service students (N=121 from diverse backgrounds - students with learning disabilities (25 LD students, 28 excellent students and 68 average students is presented in this five years research. During the online course students were asked to choose a scientific subject; to map it and to plan teaching activities; to carry out the proposed activities with students in a classroom experience; and to reflect the process. The assumption was that adapting the online course by using information and communication technology following formative assessment will improve students' self-learning ability as well as broaden their science knowledge, their lab performance and teaching skills. Data were collected using quantitative and qualitative tools including: pre and post questionnaires and nine (three students from each group depth interviews upon completion of the course. Findings, based on students` perceived evaluation, pinpointed on the advantages of the online course for students of the three groups. LD students’ achievements were not inferior to those of their peers, excellent students and average students. Yet, it carefully reports on a slight but explicitly marginal perceived evaluation of the LD students in comparison to excellent students and average students regarding: forum participation, authentic task and water lab performance. The article discusses the affordance of the online course via additional features that can be grouped into two categories: knowledge construction and flexibility in time, interaction and knowledge. Further research is suggested to extend the current study by examine the effect of other courses and different contents and by considering various evaluation methods of online courses, such as: observation, the think aloud, text and tasks analysis, and reflection.

    The aim of this study was to estimate influenza vaccine effectiveness (IVE) against laboratory-confirmed influenza among hospitalized patients. A case-control investigation was based on the prospective surveillance of influenza-like illness (ILI) during five flu seasons. We compared influenza-positive cases and influenza-negative controls. Unadjusted overall IVE was 62% (95% confidence interval 24% to 81%). We found that IVE was lower during the 2004-05 flu season (11%; 95% CI -232% to 76%) when the vaccine and circulating viruses were mismatched. Expansion of the study to other hospitals could provide IVE estimates earlier in the season, for different age groups and emerging virus strains. Copyright © 2011 Elsevier Ltd. All rights reserved.

    Saadatian-Elahi, M.; Mekki, Y.; Signore, C. del; Lina, B.; Derrough, T.; Caulin, E.; Thierry, J.; Vanhems, P.

    2007-01-01

    The purpose of the study was to calculate the seroprevalence of immunity to the varicella-zoster virus (VZV) infection and to evaluate the positive predictive value (PPV) and the negative predictive value (NPV) of the self-reported history of VZV infection in pregnant women. A cross sectional study was conducted in 18 private medical analysis laboratories. Information on socio-demographic characteristics and past history of varicella or zoster were collected using a questionnaire. Blood samples were obtained to determine the serological levels of past exposure to VZV. Overall, 486 pregnant women were recruited. The seroprevalence of VZV antibodies was 98.8%. Six women were seronegative, of whom four were primiparous. The PPV was high (99.5%) while the NPV was only 10.3%. The PPV is a reliable marker of prior VZV infection. In contrast, a negative history does not predict lack of immunity and should be completed by serological analysis which might be introduced to routine antenatal blood tests

    1994-01-01

    Aim: Retrospective analysis of Intra operative Radiotherapy (IORT) in recurrent uterine carcinoma (RUC) and prospective pilot study of IORT in advanced cervix cancer (ACC) with high risk of local failure. Patients-Treatments: (1) RUC: from 1988 to 1991, 34 patients with RUC have been treated. Primary cancer was: cervix uterus: 28, endometrium: six. Site of recurrence: centro pelvis: four, latero pelvis: 25, lombo aortic: five. Total gross resection was only possible in 12 patients. A dose of 15 to 22 Gy was given by IORT according to the residual tumour size. External beam irradiation was added in 16 patients; (2) ACC: January 1991 to November 1992, 20 patients were included in this pilot study, stage IIB: seven, stage III: 12, stage IV: 1. Preoperative retroperitoneal pelviscopy showed 13 pN1 patients and NMR imaging ten tumours of 6 cm or larger in diameter. Treatment started with concomitant pelvic irradiation (44 Gy) and one concomitant cycle of 5 Fu-CDDP, followed by a short course of high dose rate upper vagina brachytherapy (4Gy). Four weeks later a radical Wertheim operation was performed together with IORT on the lateral pelvis. Results: (1) RUC: overall survival (Kaplan Meier) at 4 years is 32% (±8). Local relapse in the field of IORT was observed in six patients. Grade 2-3 complications: six patients (radiation proctitis, neuritis, vertebral collapse, ureteral stenosis); (2) ACC: the median follow up is short (18 months). Four cases of pelvic relapse, no postoperative death. The first line radio chemotherapy was associated with two G3 early complications. Postoperative radiation complication was less than 10% G3. Discussion: promising results of IORT in RUC have been observed especially if no irradiation is given during the primary treatment. Good feasibility of the pilot study of IORT in ACC was also observed. It could be followed by a multicentric feasibility trial. (authors). 38 refs., 4 tabs., 1 fig

    The authors present a project which is still at the proto-typing stage and for which hardware and software are still being developed, and which aims at developing a full line for a robotic curietherapy. It comprises an articulated robotic arm with six degree of freedom, and is based on an auto-regulated loop with real time monitoring and control. An echographic probe acquires the prostate images in real time. An adaptive detection defines the prostate contour. This is performed in a virtual environment which comprises the prostate phantom, the robot and the intervention table. The target is defined in the virtual environment (image coordinates) and coordinates are transmitted to the robot controller which defines the robot movements by using the inverse geometric model.

    Full Text Available Customer satisfaction has long been recognized as a central concept of all business activities. Satisfaction can serve as an indicator of success of the company, both in the past and present, as well as an indicator of future performance. High quality service to students is a prerequisite of maintaining competitiveness in the market of higher education. A relationship that is created between the expectations of students and their satisfaction with the quality of service that provides educational institution plays an important role in shaping the reputation of academic institutions. Academic institutions are becoming aware of the importance of student satisfaction, because satisfaction positively influences their decision to continue their education at this institution, and the positive word of mouth that will attract prospective students. Satisfaction will affect student motivation, and therefore their performance. This paper provides insight into the marketing aspects of customer satisfaction, primarily insight into the satisfaction of students in the educational sector. The aim is to establish the influence of satisfaction various factors related to the university and higher education to the satisfaction of student life, and does student life satisfaction affect the overall happiness and student performance. The research was conducted on the student population of the University of Split, on a sample of 191 respondents. The research was conducted with the help of online survey questionnaire. The claim that student’s satisfactions with housing affect the satisfaction with the quality of student life is rejected. The results confirmed that the student’s satisfaction with university contents, university bodies and services, teaching, teaching methods and academic reputation affects the satisfaction of student life and student life satisfaction affect the student performance.

    Many times there are no ideal answers to any of the interpersonal conflicts addressed. Often the solutions to these situations may depend on an individual's characteristics or personality. By analyzing the situation and the supervisor's attitude and then changing his or her way of responding to that situation, however, the student may improve his or her problem-solving skills. The student can modify the strategies taught in these seminars to suit his or her individual needs and particular situations. A seminar like this can provide students, and thus future therapists and student supervisors, with a solid background in dealing more tactfully with a variety of conflict-ridden situations in the workplace.

    2016-09-16

    After a number of high-profile incidents and national reports, it has become clear that all health professionals and all medical students must be able to raise concerns about a colleague's behavior if this behavior puts patients, colleagues, or themselves at risk.Detailed evidence from medical students about their confidence to raise concerns is limited, together with examples of barriers, which impair their ability to do so. We describe a questionnaire survey of medical students in a single-center, examining self-reported confidence about raising concerns in a number of possible scenarios. Thematic analysis was applied to comments about barriers identified.Although 80% of respondents felt confident to report a patient safety issue, students were less confident around issues of probity, attitude, and conduct. This needs to be addressed to create clear mechanisms to raise concerns, as well as support for students during the process.

    Campo-Arias, Adalberto; Herazo, Edwin; Cogollo, Zuleima

    2010-09-01

    Homophobia is defined as a general negative attitude towards homosexual persons, with implications on public health. This fact has been less investigated among nursing students. The objective of this review was to learn about the prevalence of homophobia and its associated variables among nursing students. A systematic review was performed on original articles published in EBSCO, Imbiomed, LILACS, MEDLINE, Ovid, and ProQuest, including articles published between 1998 and 2008 in English, Portuguese and Spanish. Keywords used were homophobia, homosexuality, and nursing students. Descriptive analysis was performed. Eight studies were analyzed. The incidence of homophobia in nursing students is between 7% and 16%. Homophobia is more common among males and religious conservatism people. Homophobia is quite frequent in nursing students. This negative attitude toward homosexuality may affect services and care giving by nursing professions and could have negative implications in nursing practice.

    Sustainability issues are increasingly important in engineering work all over the world. This article explores systematic differences in self-assessed competencies, interests, importance, engagement and practices of newly enrolled engineering students in Denmark in relation to environmental and non-environmental sustainability issues. The empirical base of the article is a nation-wide, web-based survey sent to all newly enrolled engineering students in Denmark commencing their education in the fall term 2010. The response rate was 46%. The survey focused on a variety of different aspects of what can be conceived as sustainability. By means of cluster analysis, three engineering student approaches to sustainability are identified and described. The article provides knowledge on the different prerequisites of engineering students in relation to the role of sustainability in engineering. This information is important input to educators trying to target new engineering students and contribute to the provision of engineers equipped to meet sustainability challenges.

    Virginia Adams O’Connell PhD

    2014-08-01

    Full Text Available Studies on the impact of health behaviors on morbidity often focus on the limited impact of a single behavior or a limited group of behaviors. In this study, we examine college student behaviors and investigate the link of these behaviors with a 2-week illness profile. Through self-reported surveys, we measure acute illness and a general illness burden, a cumulative measure of major and minor ailments. We explore how daily routines correlate with these illness measures. Eighty-four students from a random sample of 90 students attending a small liberal arts school completed the survey for a response rate of 93%. Living arrangements, exercise, sleep patterns, eating preferences and habits, and “social” behaviors were all significantly associated with illness burden. Students living in “singles” and those who got regular exercise and an average of 7 hr of sleep per night reported less illness. Most interesting is the effect of social behaviors. Students who greet others with a handshake reported higher illness rates, as did students who share food and/or drinks. While we can conceptualize why these behaviors would lead to a greater illness burden, students who engaged more frequently in these behaviors also reported being “happier.” In trying to reduce illness among college students, we might suggest less handshaking and food and beverage sharing, but these actions are ways in which college students express and maintain friendships. College administrators are challenged to discover ways to reduce illness while maintaining the positive aspects of local student culture. This study begins to explore some ways to balance health and camaraderie.

    Full Text Available The purpose of this study was to (a identify potential benefits for students with disabilities taking part in a physical activity program with same-age typical peers on a Midwest university campus, and (b to determine if the program impacted the students with disabilities empowerment. Empowerment theory was used to determine how transition students’ attitudes change over the course of the semester while participating in a workout buddy program with same-age college peers. The program was structured to provide a sense of empowerment to students to make their own decisions and learn for themselves so they don’t feel a lack of power in their lives. This study implemented elements of a quantitative design but a majority utilized a qualitative design based on the assumptions of the Interpretivist paradigm. The quantitative design elements focused on the analysis of two questionnaires: Sports Questionnaire; and The Perceived Control Scale Questionnaire. The analysis of the focus group data revealed the following themes as positive effects of the intervention; positive effect on empowerment, how happy the program made the students, what benefits the students gained from the program, the student’s familiarity with university students, and the environment and lastly the students ability to ask for assistance when need. Findings from the study determined that the empowerment of the students with disabilities was impacted while participating in the program. In general, the findings of gaining empowerment were similar to previous studies in that students with disabilities are able to gain empowerment from participation in fitness and recreation programs. The researcher noted during focus groups that some of the BOBW students were not confident in starting conversations with their university. Although the BOBW students felt a sense of losing empowerment with this specific instance, there was an overall positive impact on the BOBW students

    Pahud, D. M.; Niembro, T.

    2014-12-01

    The SHINE workshop is an annual meeting of solar and heliospheric scientists which, in addition to aiming to improve understanding of solar disturbances and their propagation to, and effect, on the Earth (shinecon.org), is dedicated to actively supporting students. This dedication is substantiated in part through the National Science Foundation (NSF) providing funding for student attendance to the workshop, which enables student participation. Another example of SHINE's commitment to its student members is the incorporation of a Student Day prior to the workshop since 2003, entirely organized and run by two student representatives. While there are variations in format from year to year, Student Day consists of tutorials and research talks exclusively by student volunteers to an audience of only students. The day is intended to provide a low-stress environment for students to learn about the various topics addressed during the workshop, to ask questions freely, and to engage in scientific discussion with other students which hopefully is a catalyst for collaboration. As a result of positive experiences, over the past decade student attendance and participation in the workshop have increased. At the SHINE 2014 workshop, nearly a third of attendees were students. SHINE student visibility has increased over the years, with student posters being advertised at breakfast, inclusion of a student day summary by the student representatives during a plenary session, and continued support from the steering committee. Students are also promoting a broader impact of SHINE sciences via increased social media presence. From a student representative's perspective, SHINE has built and fostered a healthy student community and encourages students to engage in shaping the future of the field.

    2017-07-01

    Full Text Available The Feature for this issue Reflections on Student Persistence has been prepared by Professor Vincent Tinto, Distinguished University Professor Emeritus at Syracuse University, United States of America (USA and a longtime friend and supporter of STARS. Vincent explores the case for motivation to be considered as a significant aspect of the tertiary student psyche by drawing on theoretical frameworks, research and practical experiences related to the issue. He synthesises this extensive, detailed, rich but often somewhat impenetrable data into a trilogy of clear and credible key dimensions of the motivation construct student self efficacy, sense of belonging and perceived value of the curriculum. This interpretation of the literature is a personal but informed reflection and is a timely piece which highlights the breadth and profundity of the presentations at this year's conference in Adelaide, Australia where students in all their diversity are central to our focus on enhancing the student experience. In this opening article, Vincent refers directly to the STARS papers selected for this Conference issue of the Journal which also address the importance of student persistence, self-efficacy and building the sense of belonging within their own institutional communities (Fernandes, Ford, Rayner & Pretorius; Kahu, Nelson, & Picton; McFarlane, Spes-Skrbis & Taib; Naylor; Smallhorn. Echoing his position on social justice and his advocacy for underserved students, Vincent reminds us that educational equity gaps still exist, and he encourages us to see the issue of persistence through the eyes of the students to support their perseverance and completion and thereby help reduce educational disadvantage.

    Culver, Jennifer

    The purpose of this study was to examine the qualities of support, relatedness, and negative interaction within parent-child and teacher-student relationships and their association with cognitive, psychological, and behavioral engagement. Additionally, this study explored the contributions of cognitive and psychological engagement on behavioral engagement. The role of gender, grade, and ethnicity on relationship quality and engagement was also considered. Participants (n=311) were students in grades three through five from a suburban school district in southeastern Michigan. Perceptions of teacher-student relationship quality varied by grade level. In general, younger students reported greater teacher support and relatedness in comparison to older students. Conversely, older students perceived greater conflict within the teacher-student relationship. Student engagement also varied by grade level, with younger students reporting greater engagement than older students. Ethnicity also contributed to variance in student engagement, with African American students reporting significantly more engagement than Caucasian or Multiracial students. Teacher-student relationship quality was a significant predictor of student engagement, even after controlling for student characteristics and parent-child relationship variables. Results of path analysis revealed that cognitive and psychological engagement contributed significantly to behavioral engagement.

    Full Text Available Ageratum has a complex circumscription, and recent studies have indicated its polyphyletism. The genus has been placed in the tribe Eupatorieae whose embryology is not fully known. Embryological data are conservative and important indicators of phylogenetic relationships and can improve family relationships. This study presents, for the first time in Eupatorieae, embryological data for Ageratum conyzoides and A. fastigiatum. Both species have common features of the family such as a unitegmic anatropous ovule, basal placentation, secretory tapetum, Polygonum megagametophyte, and Asterad embryogenesis. The data obtained reinforce the heterogeneity of the family embryology and show, for the first time, the anther wall development of the monocotyledonous type for Asteraceae. The species studied show also differences between themselves. A. conyzoides has bisporangiated and introrse anthers, conspicuous pappus, and cypselae with trichomes on the ribs, whereas A. fastigiatum has tetrasporangiate and latrorse anthers, pappus absent at maturity, and glabrous cypselae. The data presented support recent phylogenetic molecular studies, suggesting the replacement of A. fastigiatum to another genus along with Gyptidinae.

    Full Text Available Disaster is an event that suddenly or slowly occurs caused by human, nature, or even both. Disaster is not only related to the physical environment where disaster found but also to the livelihood of the community. Coastal rural is vulnerable to the coastal disaster such as flood and tidal flood due to their high dependency on the coastal resources. The vulnerability assessment of the coastal rural is very important in order to identify the level of vulnerability and to recommend crucial strategies to reduce the risk of disaster exposure in the future. This study aims to identify the socio-economic vulnerability in the rural coastal community of Demak Regency. Vulnerability assessment was carried out through a spatial explicit modeling. The results show that 33 (thirty-three villages or about 42% were categorized as most vulnerable. While, 45 (forty-five others or about 59% are less vulnerable. Therefore, efforts on the disaster mitigation are necessary to be done to reduce the exposure impact to the coastal rural community.

    Wei, Xueyan; Wang, Rongrong; Macdonald, Elizabeth

    2015-08-01

    Research on the negative effects of student cynicism has been limited, especially regarding its relation to student burnout. This study examined the relations among student cynicism (policy cynicism, academic cynicism, social cynicism, and institutional cynicism) and student burnout, as evidenced by emotional exhaustion, depersonalization, and reduced personal accomplishment, in a sample of 276 Chinese undergraduates. Hierarchical multiple regressions showed that four aspects of student cynicism together explained substantial variance in student burnout. Policy cynicism was the strongest contributor to emotional exhaustion. Social cynicism was the primary contributor to depersonalization, and also to reduced personal accomplishment. Student cynicism overall had the strongest relationship with reduced sense of personal achievement. The findings outline the negative functional relations between student cynicism and student burnout.

    Full Text Available Actuality of work. Student age has the most favourable conditions for psychological, biological and social development; however, there are reasons why such natural advantages over other social groups can be completely or partially levelled. One of them is the presence of conflicts in the life of a student, a special group, among which there are women. The causes of the emergence of gender conflicts in individual social groups and the strategies for their solution have not been sufficiently explored and require further study and, therefore, are relevant. Purpose of the article is to investigate the causes of gender conflicts among students as a separate social group and to develop measures to address them and prevent them. Methodology. The research conducted in the work is based on the analysis and generalization of the causes of the emergence of gender conflicts among students, the identification of the main sources of information that form the consciousness of children and adolescents, and also influence their attitude to gender equality. Originality. The nature of gender conflicts has been quite effectively studied for a long time. However, the scope of research is limited to the most numerous social groups, such as the family, labour collective, political and public organizations, etc. Being a dynamic and socio-demographic formation, the students perform an important function in society – it takes a direct part in the transformation of all spheres of the life activity of the society. Based on the study of the objective conditions of the social environment with certain models of socialization that form the consciousness of students from early childhood, a three-component system of influence was first proposed, which is aimed at overcoming gender inequality and preventing gender conflicts among students. At the same time, the interaction of the components of the system will allow to minimize the gender inequality index in our country

This is the main question in Bruce Macfarlane’s book Freedom to learn - The Threat to Student Academic Freedom and Why it Needs...... to be Reclaimed (2017). In eighth well-written chapters, Macfarlane explores an often-overlooked paradox in higher education teaching and learning: The idea of the student centered learning, deriving from humanist psychology and progressive pedagogy, has been hijacked by increased and continuous demands of bodily......, cognitive and emotional performance that restricts students’ freedom to develop as autonomous adults.

    Fostering and maintaining students' interest in science is an important aspect of improving science learning. The focus of this paper is to listen to and reflect on students' voices regarding the sources of motivation for science subjects among students in community secondary schools with contextual challenges in Tanzania. We conducted a group-interview study of 46 Form 3 and Form 4 Tanzanian secondary school students. The study findings reveal that the major contextual challenges to student motivation for science in the studied schools are limited resources and students' insufficient competence in the language of instruction. Our results also reveal ways to enhance student motivation for science in schools with contextual challenges; these techniques include the use of questioning techniques and discourse, students' investigations and practical work using locally available materials, study tours, more integration of classroom science into students' daily lives and the use of real-life examples in science teaching. Also we noted that students' contemporary life, culture and familiar language can be utilised as a useful resource in facilitating meaningful learning in science in the school. Students suggested that, to make science interesting to a majority of students in a Tanzanian context, science education needs to be inclusive of students' experiences, culture and contemporary daily lives. Also, science teaching and learning in the classroom need to involve learners' voices.

  17. Students' understandings of electrochemistry

    Science.gov (United States)

    O'Grady-Morris, Kathryn

    Electrochemistry is considered by students to be a difficult topic in chemistry. This research was a mixed methods study guided by the research question: At the end of a unit of study, what are students' understandings of electrochemistry? The framework of analysis used for the qualitative and quantitative data collected in this study was comprised of three categories: types of knowledge used in problem solving, levels of representation of knowledge in chemistry (macroscopic, symbolic, and particulate), and alternative conceptions. Although individually each of the three categories has been reported in previous studies, the contribution of this study is the inter-relationships among them. Semi-structured, task-based interviews were conducted while students were setting up and operating electrochemical cells in the laboratory, and a two-tiered, multiple-choice diagnostic instrument was designed to identify alternative conceptions that students held at the end of the unit. For familiar problems, those involving routine voltaic cells, students used a working-forwards problem-solving strategy, two or three levels of representation of knowledge during explanations, scored higher on both procedural and conceptual knowledge questions in the diagnostic instrument, and held fewer alternative conceptions related to the operation of these cells. For less familiar problems, those involving non-routine voltaic cells and electrolytic cells, students approached problem-solving with procedural knowledge, used only one level of representation of knowledge when explaining the operation of these cells, scored higher on procedural knowledge than conceptual knowledge questions in the diagnostic instrument, and held a greater number of alternative conceptions. Decision routines that involved memorized formulas and procedures were used to solve both quantitative and qualitative problems and the main source of alternative conceptions in this study was the overgeneralization of theory

    Full Text Available Communicative competence is the ability to send messages which promote attainment of goals while maintaining social acceptability. Competent communicators attempt to align themselves with each others goals and methods to produce a smooth, productive and often enjoyable dialogue. The aim of this research was to investigate self-perceived communicative competence (SPCC of students of Engineering Management in General English and English for Specific Purposes (ESP. A longitudinal study was carried out starting with the first year students at the Faculty of Technical Sciences in Novi Sad and was repeated with the same sample of students during their second and third year of study. Participation was voluntary and took place during regular class time. The measure of communicative competence employed was the Self-perceived Communication Competence Scale. The results of the study indicated that differences in SPCC between the years do exist. The SPCC gradually improved between the first, the second and the third year. The research was also motivated by gaining better overview of the teaching activity. An anonymous questionnaire provided many useful hints and ideas for further work and thus, language teacher made a thorough analysis of the overall teaching procedure. However, it is essential to get some feedback and talk to students in order to evaluate both them and ourselves as well as the teaching syllabus.
