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.

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

Cuevas, E; Rosas-Guerrero, V

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.

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.

Women healers in the medical marketplace of 16th-century Lyon.

Klairmont-Lingo, A

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.

The research method used is descriptive qualitative research method. The direct location of flooding review is at Jalan Serdang which belongs to Belawan I urban village. The result shows that the rob flood that hit Medan Belawan District has varying height. Several villages affected by the flood were Belawan I, Belawan II, Belawan Bahagia, Belawan Bahari, Belawan Sicanang and Bagan Deli. Rob flood occurs twice a day at around 02.00 am and 13.00 pm to 16.00 pm. Rob floods give impacts of damage to buildings especially shelter, increased salinity of water resources, damage to pond land, damage to work equipment or vehicles used by everyday people. Rob floods also disrupt the activities of fishers and traders because when the floods occur, fishers are forced to stop while fishing and income is reduced, as well as the supply of fish to the market. Community adaptation to rob floods in Medan Belawan District is adaptation to residential buildings and adaptation to the availability of clean water sources.

When attempts at robbing prey turn fatal

Dejean, Alain; Corbara, Bruno; Azémar, Frédéric; Carpenter, James M.

2012-07-01

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.

Effects of nectar robbing on male and female reproductive success of a pollinator-dependent plant.

Science.gov (United States)

Rojas-Nossa, Sandra V; Sánchez, José María; Navarro, Luis

2016-02-01

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.

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.

Experimental design and data-analysis in label-free quantitative LC/MS proteomics: A tutorial with MSqRob.

Goeminne, Ludger J E; Gevaert, Kris; Clement, Lieven

2018-01-16

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.

RobOKoD: microbial strain design for (over)production of target compounds.

Science.gov (United States)

Stanford, Natalie J; Millard, Pierre; Swainston, Neil

2015-01-01

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.

During this process within the subthrusting belt a geomorphologic step was formed at sites where limestone became overthrust on flyschbeds.Apartof this geomorphologic step became known in the last decade of 20st century as the Kraški rob (Karst edge. With respect to geologic and geomorphologic considerations the term Kra{ki rob (»Karst Edge« as landscape term for cliffs above the valleys of the Osapska reka and upper Rižana rivers should be distinguished from term karst edge (kra{ki rob as a general term which is a synonym for the geomorphologic step consisting of precipitous cliffs and steep carbonate slopes situated entirely between the mouth of the river Timava and Mt.

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.

Directory of Open Access Journals (Sweden)

Ricardo Zorrón

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

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)

Full Text Available O desenvolvimento de técnicas minimamente invasivas é um dos mais importantes avanços da cirurgia colorretal. A assistência robótica integra o arsenal de técnicas em cirurgia minimamente invasiva, e vem sendo aplicado em cirurgia colorretal por um restrito grupo de cirurgiões em alguns centros ao redor do mundo com resultados iniciais que merecem atenção. O objetivo do presente estudo é analisar os resultados do emprego da assistência robótica em videocirurgia colorretal. Dentre as vantagens associadas ao emprego de robôs em videocirurgia colorretal, figuram o incremento na precisão dos movimentos e a visão tridimensional. A experiência clínica é ainda pequena, e advém de uma série de casos e estudos comparativos com a videocirurgia colorretal sem assistência robótica com ainda pequeno número de casos. A dissecção pélvica com incremento da preservação autonômica parece ser a maior vantagem associada à assistência robótica em videocirurgia colorretal. Somente através do treinamento de um número mais representativo de cirurgiões colorretais, bem como com a expansão da experiência clínica será possível prever com maior precisão o papel da assistência robótica em videocirurgia colorretal.The development of minimally invasive surgical techniques represents an important aspect of modern surgical research.

Test Particle Simulations of Electron Injection by the Bursty Bulk Flows (BBFs) using High Resolution Lyon-Feddor-Mobarry (LFM) Code

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.

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.

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

Science.gov (United States)

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.

Full Text Available O desenvolvimento de sistemas robóticos para cirurgia teve início na década de 80, por solicitação do exército norte-americano, que antevia a possibilidade de realizar operações em teatros de guerra, distantes do local onde estava o cirurgião. Entretanto, o primeiro uso em humanos só ocorreu anos mais tarde, numa ressecção transuretral de hiperplasia benigna de próstata. 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

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.

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.

Full Text Available Dans cet article, l’auteur s’interroge sur une dispute autour de la création d’une commission communale consultative de prévention situationnelle, dispositif expérimental mis en œuvre à Lyon pour expertiser les projets de sécurisation (lutte contre le crime des espaces urbains. En mobilisant la grille de la sociologie des épreuves, l’auteur analyse ce moment critique où les personnes en charge de l’urbanisme et celles responsables de la sécurité ont dû s’affronter et se mesurer autour de son acceptabilité et de sa définition. L’enjeu est de prendre au sérieux les logiques de justification des personnes afin d’analyser comment elles parviennent à trouver un accord. On voit que la prévention situationnelle apparaît comme un formidable catalyseur des débats autour du sens de la ville. En créant ce dispositif expérimental, la Ville de Lyon a produit sans en avoir l’intention, un espace de discussion et de cadrage de la controverse autour de la prévention situationnelle. Cette dernière apparaît comme le moyen pour les personnes en charge de la sécurité et de l’urbanisme de s’approprier un certain nombre de questions politiques et morales en mettant en avant la supériorité du politique sur la compétence technicienne.In this article, the author examines a dispute on the establishment of a municipal advisory committee on situational crime prevention, an experimental device implemented in Lyon to integrate safety in urban area planning. The author analyzes the critical moment when people in charge of planning and those of safety had to compete and measure themselves around its acceptability and its definition. The challenge is to take seriously the logic of justification of people in order to analyze how they find an agreement. We observe that situational crime prevention appears like a great catalyst of the debate about the meaning of the city. In creating this experimental instrument, the City of Lyon

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.

Simulación de Plataformas Robóticas de Movimiento para Aplicaciones de Realidad Virtual Mediante Filtros Digitales

2017-10-01

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.

Development of RadRob15, A Robot for Detecting Radioactive Contamination in Nuclear Medicine Departments

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.

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.

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.

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.

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

Science.gov (United States)

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.

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. Este estudo investiga: "qual é o mérito acadêmico da utilização de telescópios robóticos Slooh para ensinar astronomia, tal como percebido pelos professores de ciências?"

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.

GREENLYS. Grenoble and Lyon experiment with smart energy of the future

International Nuclear Information System (INIS)

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

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

Science.gov (United States)

Musio, Alessio

2018-01-01

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″.

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.

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.

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.

Sahajian, F; Berger-Vergiat, A; Pot, E

2017-09-01

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).

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.

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.

Lasche, George; Coldwell, Robert; Metzger, Robert

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.

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

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.

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.

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.

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.

Le rôle de l’intertexte et du palimpseste dans la création d’une Écosse mythique dans Waverley et Rob Roy de Walter Scott

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

This research focused on the phytochemical characterization of the species Smallanthus pyramidalis (Triana) H. Rob. in order to identify the secondary metabolites of flowers and leaves. This is due to the importance these trees on the sustainable development of the wetlands in the Sabana de Bogota, and its possible application as a promising species in the use and conservation of these ecosystems. We performed preliminary chemical tests, fractionation using conventional techniques, identification of physical and chemical properties, and structural analysis using spectroscopic and spectrometric techniques, such as UV, 1H-RMN, 13C-RMN and GC-MS. We identified alkane-type compounds, steroids, terpenoids and flavonoids mainly, and their role in the plant and the ecosystem.

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

International Nuclear Information System (INIS)

Holdoway, K.A.

1972-01-01

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

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.

A New Deal for Southeastern Archaeology, by Edwin A. Lyon, The University of Alabama Press

1996-05-01

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.

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.

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.

MEEREB is an inter-regional network of countries from North Africa, Europe, the Middle East and Central Asia that work together with the aim of improving rabies control and prevention at local, regional and global level. 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. They called for elimination of dog-transmitted rabies through vaccine and rabies immunoglobulin stockpiles and implementation of a One Health approach to achieve rabies's eradication.

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.

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.

To evaluate the risk of bias (ROB) in reports of randomised controlled trials (RCTs) of animal experiments published in implant dentistry, and to explore the association between animal experiment characteristics and ROB. We searched the MEDLINE (via PubMed), SCOPUS and SciELO databases from 2010 to March 2015 for reports of RCTs of animal experiments published in implant dentistry. We evaluated independently and in duplicate the ROB of these experiments by the use of a tool specifically developed to evaluate ROB in animal studies, the SYRCLE's tool. ROB was judged as low, high or unclear (when there was not enough information to judge ROB). We used univariate and multivariate logistic regression analyses to evaluate the association of specific study characteristics and extent of ROB. We initially selected 850 publications and 161 reports of animal experiments were included. For a total of 1449 entries (records), 486 (34%) were rated as low ROB. High ROB was attributed to 80 (6%) of entries, and 883 (60%) entries were rated as unclear ROB. The characteristics "impact factor" (IF), reporting of standard error (SE) and reporting of confidence interval (CI) were significantly associated with low ROB in some SYRCLE domains. A substantial number of items with unclear ROB were observed in this sample of animal experiments in implant dentistry. Furthermore, the present findings suggest that implant dentistry animal experiments published in journals with higher IF and better report of measures of precision; that is, CI and SE may have lower ROB than those not having these characteristics. © 2016 John Wiley & Sons A/S.

Functional electrical stimulation cycling strategies tested during preparation for the First Cybathlon Competition – a practical report from team ENS de Lyon

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.

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

To study the chromosomal risk in sperm from Robertsonian translocation (RobT) carriers as a function of the sperm count and translocation type. Prospective study. Departments of reproductive biology, cytogenetics, gynecology, and obstetrics. A total of 29 RobT patients (8 normozoospermic and 21 oligozoospermic) and 20 46,XY patients (10 normozoospermic and 10 oligozoospermic). Sperm fluorescence in situ hybridization with probes for translocation malsegregation and chromosome 13, 18, 21, X, and Y probes for studying the interchromosomal effect (ICE). Translocation malsegregation and ICE aneuploidy rates. In RobT carriers, the sperm translocation malsegregation rate was significantly lower in normozoospermic patients (9.7%) than in oligozoospermic patients (18.0%). Considering only oligozoospermic patients, sperm malsegregation rates were significantly lower for rob(14;21) than for rob(13;14) (11.4% vs. 18.9%). In turn, the rates were significantly lower for rob(13;14) than for rare RobTs (18.9% vs. 25.3%). In sperm from normozoospermic RobT, an ICE was suggested by higher chromosome 13 and 21 aneuploidy rates than in control sperm. Conversely, chromosome 13 and 21 sperm aneuploidy rates were lower in oligozoospermic RobT patients than in oligozoospermic 46,XY patients, but higher than in control subjects. Both translocation type and sperm count influence the RobT malsegregation risk. Of the chromosomes analyzed (13, 18, 21, X, and Y), only chromosomes 13 and 21 were found to be associated with an ICE. Relative to the RobT effect, idiopathic alterations in spermatogenesis in 46,XY patients appear to be more harmful for meiosis. Copyright © 2011 American Society for Reproductive Medicine.

Santana, P. H. S.; Shida, R. Y.

2003-08-01

O principal objetivo do projeto Observatórios Virtuais é o ensino na área de ciências através de atividades práticas desenvolvidas em colaboração entre instituições de pesquisa em astronomia e escolas de ensino médio e fundamental. Este ano deverá ser concluída a implantação do programa piloto de estudos, pesquisas e observação astronômica direta, com utilização em tempo real de telescópios robóticos, que assim funcionarão como "observatórios virtuais". O objetivo pedagógico das atividades práticas baseadas nas imagens atronômicas é desenvolver as habilidades e competências dos alunos no uso do método científico. Para isso, serão realizados projetos interdisciplinares, a partir de observações astronômicas, já que a astronomia é uma área interdisciplinar por excelência. Essas atividades terão níveis diferenciados de complexidade, que podem ser adequados aos vários graus do ensino e realidades regionais. Será dada ênfase ao desenvolvimento e aplicação em São Paulo, onde atua a equipe do IAG/USP. Como resultados apresentados no presente trabalho, temos a criação de um software em português para o processamento de imagens obtidas através de CCDs e a elaboração de material para as atividades educacionais relacionadas.

The aim of this study was to compare the short-term outcomes of robotic rectal resection with total mesorectal excision (TME) for rectal cancer, with the use of the new da Vinci Xi® (Xi-RobTME group) and the da Vinci Si® (Si-RobTME group). Ten patients with histologically confirmed rectal cancer underwent robot-assisted TME with the use of the new da Vinci Xi. The outcomes of Xi-RobTME group were compared with a Si-RobTME group selected using a case-matched methodology. Overall operative times and mean hospital stays were shorter in the Xi-RobTME group. Surgeries were fully robotic with a complete take-down of the splenic flexure in all Xi-RobTME cases, while only four cases of the Si-RobTME group were fully robotic, with two cases of complete take-down of the splenic flexure. The new da Vinci Xi could offer some advantages with respect to the da Vinci Si in rectal resection for cancer. Copyright © 2016 John Wiley & Sons, Ltd. Copyright © 2016 John Wiley & Sons, Ltd.

Francois, M; Girard, R; Mauranne, C C; Ruffion, A; Terrier, J E

2017-12-01

The surgical hand disinfection by friction (SDF) helps to reduce the risk of surgical site infections. For this purpose and in order to promote good compliance to quality care, the urology service of Centre Hospitalier Lyon Sud achieved a continuous internal audit to improve the quality of the SDF. An internal audit executed by the medical students of urology was established in 2013. The study population was all operators, instrumentalists and operating aids of urology operating room (OR). Each student realized 5-10 random observations, of all types of professionals. The criteria measured by the audit were criteria for friction. The evolution of indicators was positive. Particularly, the increasing duration of the first and second friction was statistically significant during follow-up (P=0.001). The total duration of friction shows a similar trend for all professionals. The surgical hand disinfection by friction in the urology OR of the Centre Hospitalier Lyon Sud has gradually improved over the iterative audits. Copyright © 2017 Elsevier Masson SAS.

For child health randomized controlled trials (RCTs) published in 2012, we aimed to describe design and reporting characteristics and evaluate changes since 2007; assess the association between trial design and registration and risk of bias (RoB); and assess the association between RoB and effect size. For 300 RCTs, we extracted design and reporting characteristics and assessed RoB. We assessed 5-year changes in design and reporting (based on 300 RCTs we had previously analyzed) using the Fisher exact test. We tested for associations between design and reporting characteristics and overall RoB and registration using the Fisher exact, Cochran-Armitage, Kruskal-Wallis, and Jonckheere-Terpstra tests. We pooled effect sizes and tested for differences by RoB using the χ 2 test for subgroups in meta-analysis. The 2012 and 2007 RCTs differed with respect to many design and reporting characteristics. From 2007 to 2012, RoB did not change for random sequence generation and improved for allocation concealment (P < .001). Fewer 2012 RCTs were rated high overall RoB and more were rated unclear (P = .03). Only 7.3% of 2012 RCTs were rated low overall RoB. Trial registration doubled from 2007 to 2012 (23% to 46%) (P < .001) and was associated with lower RoB (P = .009). Effect size did not differ by RoB (P = .43) CONCLUSIONS: Random sequence generation and allocation concealment were not often reported, and selective reporting was prevalent. Measures to increase trialists' awareness and application of existing reporting guidance, and the prospective registration of RCTs is needed to improve the trustworthiness of findings from this field.

Collins, Sarah A; Tulikangas, Paul K; O'Sullivan, David M

2012-05-01

We sought to compare recovery of activity and pain control after robotic (ROB) vs abdominal (ABD) sacral colpopexy. Women undergoing ROB and ABD sacral colpopexy wore accelerometers for 7 days preoperatively and the first 10 days postoperatively. They completed postoperative pain diaries and Short Form-36 questionnaires before and after surgery. At 5 days postoperatively, none of the 14 subjects in the ABD group and 4 of 28 (14.3%) in the ROB group achieved 50% total baseline activity counts (P = .283). At 10 days, 5 of 14 (35.7%) in the ABD group and 8 of 26 (30.8%) in the ROB group (P = .972) achieved 50%. Postoperative pain was similar in both groups. Short Form-36 vitality scores were lower (P = .017) after surgery in the ABD group, but not in the ROB group. Women undergoing ROB vs ABD sacral colpopexy do not recover physical activity faster, and pain control is not improved. Copyright © 2012 Mosby, Inc. All rights reserved.

Only one of this five had very high factor loadings. The remaining four indicators had more measurement error than common variance with the RoB latent factor. Together, the five indicators showed poor reliability (ω = 0.687; 95% CI: 0.613–0.761.ConclusionAlthough the Cochrane model of RoB for ASD exhibited good fit indices, the majorities of the items have more residual variance than common variance and, therefore, did not adequately capture the RoB in ASD intervention trials.

Physical and chemical characterization of residential oil boiler emissions.

2008-04-01

The toxicity of emissions from the combustion of home heating oil coupled with the regional proximity and seasonal use of residential oil boilers (ROB) is an important public health concern. Yet scant physical and chemical information about the emissions from this source is available for climate and air quality modeling and for improving our understanding of aerosol-related human health effects. The gas- and particle-phase emissions from an active ROB firing distillate fuel oil (commonly known as diesel fuel) were evaluated to address this deficiency. Ion chromatography of impactor samples showed that the ultrafine ROB aerosol emissions were approximately 45% (w/w) sulfate. Gas chromatography-mass spectrometry detected various n-alkanes at trace levels, sometimes in accumulation mode particles, and out of phase with the size distributions of aerosol mass and sulfate. The carbonaceous matter in the ROB aerosol was primarily light-adsorbing elemental carbon. Gas chromatography-atomic emission spectroscopy measured a previously unrecognized organosulfur compound group in the ROB aerosol emissions. High-resolution transmission electron microscopy of ROB soot indicated the presence of a highly ordered primary particle nanostructure embedded in larger aggregates. Organic gas emissions were measured using EPA Methods TO-15 and TO-11A. The ROB emitted volatile oxygenates (8 mg/(kg of oil burned)) and olefins (5 mg/(kg of oil burned)) mostly unrelated to the base fuel composition. In the final analysis, the ROB tested was a source of numerous hazardous air pollutants as defined in the Clean Air Act Amendments. Approximations conducted using emissions data from the ROB tests show relatively low contributions to a regional-level anthropogenic emissions inventory for volitile organic compounds, PM2.5, and SO2 mass.

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.

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.

Radiotherapy of macular lesions in age-related macular degeneration (A.M.D.): preliminary results of a clinical study conducted in Lyon, France

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)

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

An Internet-Based Radiology Course in Medical School: Comparison of Academic Performance of Students on Campus Versus Those With Absenteeism Due to Residency Interviews.

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

The former Lyon-Perrache gas works (France). Diagnosis and preliminary treatment in view of the re-use of a site in an urban zone

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

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].

Background Risk of bias (ROB) may threaten the internal validity of a clinical trial by distorting the magnitude of treatment effect estimates, although some conflicting information on this assumption exists. Objective The objective of this study was evaluate the effect of ROB on the magnitude of treatment effect estimates in randomized controlled trials (RCTs) in periodontology and implant dentistry. Methods A search for Cochrane systematic reviews (SRs), including meta-analyses of RCTs published in periodontology and implant dentistry fields, was performed in the Cochrane Library in September 2014. Random-effect meta-analyses were performed by grouping RCTs with different levels of ROBs in three domains (sequence generation, allocation concealment, and blinding of outcome assessment). To increase power and precision, only SRs with meta-analyses including at least 10 RCTs were included. Meta-regression was performed to investigate the association between ROB characteristics and the magnitudes of intervention effects in the meta-analyses. Results Of the 24 initially screened SRs, 21 SRs were excluded because they did not include at least 10 RCTs in the meta-analyses. Three SRs (two from periodontology field) generated information for conducting 27 meta-analyses. Meta-regression did not reveal significant differences in the relationship of the ROB level with the size of treatment effect estimates, although a trend for inflated estimates was observed in domains with unclear ROBs. Conclusion In this sample of RCTs, high and (mainly) unclear risks of selection and detection biases did not seem to influence the size of treatment effect estimates, although several confounders might have influenced the strength of the association.

The Journal of Magnetic Resonance has played a prominent role in encouraging synergies between physical insights and biophysical applications. In this Virtual Special Issue (VSI), JMR's associate editor Dr. Robert (Rob) Tycko highlights the state-of-the-art in this area, by presenting a compilation of JMR articles published over recent years that demonstrate the value of indirect detection methods in biosolids NMR. This is a topic that Rob knows only too well, having been one of its founders and main expositors. This thematic VSI also gives a perfect "excuse" for thanking Rob for the seven years that he has served as our card-carrying solids NMR associate editor. His work for the Journal was, like all other NMR endeavors in which Rob has embarked, characterized by utmost excellence. Over the years he contributed numerous ideas and initiatives, while providing editorial judgment in the handling of over 320 individual papers. For all this we in the NMR community wish to extend Rob our sincere thanks; to offer him our best wishes for a continued successful career and happiness in all walks of life, and to express our hope that we can keep on counting on his wisdom and advice as member of our Editorial Board. I would also like to use this opportunity to extend a warm welcome to Chad Rienstra, who will be replacing Rob in his role of associate editor. Chad: You have some big shoes to fill in, but we all know that you will be up to the challenge!

Robotic rectal resection with da Vinci Si has some technical limitations, which could be overcome by the new da Vinci Xi. We compare short-term surgical and functional outcomes following robotic rectal resection with total mesorectal excision for cancer, with the da Vinci Xi (Xi-RobTME group) and the da Vinci Si (Si-RobTME group). The first consecutive 30 Xi-RobTME were compared with a Si-RobTME control group of 30 patients, selected using a one-to-one case-matched methodology from our prospectively collected Institutional database, comprising all cases performed between April 2010 and September 2016 by a single surgeon. Perioperative outcomes were compared. The impact of minimally invasive TME on autonomic function and quality of life was analyzed with specific questionnaires. The docking and overall operative time were shorter in the Xi-RobTME group (p  25 kg/m 2 was necessary in ten patients (45 vs. 0%, p da Vinci Xi seem to be mainly associated with a shorter docking and operative time and with superior ability to perform a fully-robotic approach. Clinical and functional outcomes seem not to be improved, with the introduction of the new Xi platform.

Background. Chinese herbal medicines reportedly increase efficacy and minimize toxicity of chemotherapy; however, little attention has been paid to how poor study quality can bias outcomes. Methods. We systematically searched MEDLINE, TCMLARS, EMBASE, and Cochrane Library for randomized controlled trials of Chinese herbal medicines combined with fluorouracil-based chemotherapy compared with the same chemotherapy alone. We screened for eligibility, extracted data, and pooled data with random-effects meta-analysis. Outcome measures were survival, toxicity, tumor response, performance status, quality of life, and Cochrane Risk of Bias (ROB) criteria to critically evaluate the quality of reporting in the randomized trials included in the meta-analysis. Results. We found 36 potentially eligible studies, with only 3 (those with low ROB) qualifying for meta-analysis. Two reported chemotherapy-related diarrhea reduced by 57% (relative risk [RR] = 0.43; 95% CI = 0.19-1.01; I2 test for variation in RR due to heterogeneity = 0.0%), with nonsignificant results. Two reported white blood cell toxicity reduced by 66% (RR = 0.34; 95% CI = 0.16-0.72; I2 test for variation in RR due to heterogeneity = 0.0%), with statistically significant results. Stratifying analysis by studies with high versus low ROB, we found substantial overestimation of benefit: Studies with high ROB overestimated by nearly 2-fold reduction of platelet toxicity by Chinese herbal medicines (RR = 0.35, 95% CI = 0.15-0.84 vs RR = 0.65, 95% CI = 0.11-3.92). Studies with high ROB overestimated by nearly 2-fold reduction of vomiting toxicity (RR = 0.45, 95% CI = 0.33-0.61 vs RR = 0.87, 95% CI = 0.48-1.58). And, studies with high ROB overestimated by 21% the reduction in diarrhea toxicity (RR = 0.34, 95% CI = 0.20-0.58 vs RR = 0.43, 95% CI = 0.19-1.01). Studies with high ROB also overestimated by 16% improvement in tumor response (RR = 1.39, 95% CI = 1.18-1.63 vs RR = 1.20; 95% CI = 0.81-1.79). Not accounting for ROB

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.

Veterinary homeopathy: systematic review of medical conditions studied by randomised trials controlled by other than placebo.

Science.gov (United States)

Mathie, Robert T; Clausen, Jürgen

2015-09-15

No systematic review has previously been carried out on randomised controlled trials (RCTs) of veterinary homeopathy in which the control group was an intervention other than placebo (OTP). For eligible peer-reviewed RCTs, the objectives of this study were to assess the risk of bias (RoB) and to quantify the effect size of homeopathic intervention compared with an active comparator or with no treatment. Our systematic review approach complied fully with the PRISMA 2009 Checklist. Cochrane methods were applied to assess RoB and to derive effect size using standard meta-analysis methods. Based on a thorough and systematic literature search, the following key attributes of the published research were distinguished: individualised homeopathy (n = 1 RCT)/non-individualised homeopathy (n = 19); treatment (n = 14)/prophylaxis (n = 6); active controls (n = 18)/untreated controls (n = 2). The trials were highly diverse, representing 12 different medical conditions in 6 different species. No trial had sufficiently low RoB to be judged as reliable evidence: 16 of the 20 RCTs had high RoB; the remaining four had uncertain RoB in several domains of assessment. For three trials with uncertain RoB and without overt vested interest, it was inconclusive whether homeopathy combined with conventional intervention was more or was less effective than conventional intervention alone for modulation of immune response in calves, or in the prophylaxis of cattle tick or of diarrhoea in piglets. Due to the poor reliability of their data, OTP-controlled trials do not currently provide useful insight into the effectiveness of homeopathy in animals.

The second national ranking test took place in 2005 in the same conditions as the year before. Analysis of the results permits us to assess whether the objectives of this reform have been met so far. Data crossing of the results provided by the national testing center allowed us to rank: 1) the appeal of specializations for each geographic subdivision, 2) the candidates by medical school, and 3) the appeal of each subdivision by candidate rank. 66% of the students were classified high enough to be able to choose any specialization. Trends observed from the first examination, in 2004, were confirmed, with the clear desirability of medical specializations and a certain lack of interest in occupational medicine and public health. All the surgery posts were filled, even though the number of posts had increased enormously since the first examination. After adjustment for the number of posts available, the specializations in decreasing order of popularity were: medical, surgical, pediatrics, anesthesiology, gynecology-obstetrics, general medicine, psychiatry, and biology. Approximately 1000 posts in general medicine were not filled. The medical schools whose students ranked highest were Paris Pitié, Paris V, Paris West, Lyon North, Grenoble, and Aix-Marseille. Some medical schools did less well than previously: Marseille very slightly and Angers substantially. Strasbourg, Nancy Amiens and Bobigny were at the bottom of the list. The cities most desired for internships were Paris, Toulouse, Lyon, and Aix-Marseille, while Brest, Nancy, Limoges and the West Indies were ranked lowest, although each was chosen by highly ranked candidate. Two thirds of the students were ranked high enough to allow them a free choice of specializations. All the specializations except public health and occupational medicine had very highly ranked students. Medical specializations are the most desired, but surgery remains highly demanded, despite a substantial increase in the number of posts. All

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

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.

Kim, K T

1990-09-01

The periodontium, especially the periodontal ligament and alveolar bone, are tissues constantly subjected to physical stress such as occlusion and mastication. This study was designed to explore the effect of the pulsed electromagnetic fields (PEMF) on the cell attachment and the spread of human periodontal ligament fibroblasts (HPLF) and rat osteoblasts (ROB). PEMF are categorized as one type of mechanical stress. HPLF were obtained by the explantation method described by Saito et al. They were then subcultured in Dulbecco's modified Eagle's medium (D-MEM) and supplemented with 2 mg/ml dialyzed fetal calf serum protein (FCSP), 50 micrograms/ml ascorbic acid and penicillin/streptomycin after trypsinization. ROB were isolated from a two-day-old rat calvaria by the sequential bacterial collagenase digestion method described by Dziak and Brand and were subcultured in D-MEM supplemented with FCSP, ascorbic acid and penicillin/streptomycin. After the confluent HPLF were cultured with serum-free MCDB 107 medium, the quiescent HPLF were exposed with or without PEMF for 24 hr. This was followed by the collection of the control conditioned medium (C-CM) and PEMF exposed conditioned medium (PEMF-CM). The cell attachment assay was performed so that the hydrophobic 24 multiwells were coated with the whole conditioned medium or fractionated conditioned medium by a PO-60K column. After coating, heat inactivated BSA blocked nonspecific sites for cell adhesion, and 3H-TdR labeled HPLF or ROB were cultured on the precoated wells. The activity of cell attachment and spreading was determined by the radioactivity of 3H-TdR using a scintillation counter. The characters of cell attachment factors derived from HPLF were hydrophobic, heat labile and proteolytic enzyme digestible. In addition, the fractionated PEMF-CM enhanced the spreading activity of ROB. PEMF induced the 10 KDa which can enhance the HPLF and ROB spreading. Therefore, the cell attachment and spreading factors secreted by

Full Text Available Resumen: Hoy en día, los robots manipuladores están presentes en todas las instalaciones de producción moderna industriales. 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. En concreto se propone una aproximación basada en un sub-conjunto de diagramas UML (diagrama de componentes y diagrama de despliegue para el diseño de este tipo de aplicaciones.

The hydrogen cluster accelerator of the Institut de Physique Nucleaire de Lyon (IPN Lyon) has been upgraded by adding a Variable Energy Post-accelerator of RFQ type (VERFQ). This operation has been performed in the frame of a collaboration between KfK Karlsruhe, IAP Frankfurt and IPN Lyon. The facility has been designed to deliver beams of mass selected Hn + clusters, n chosen between 3 and 49, in the energy range 65-100 keV/u. For the first time, hydrogen clusters have been accelerated at energies as high as 2 MeV. This facility opens new fields for experiments which will greatly benefit from a velocity range never available until now for such exotic projectiles. (author) 13 refs.; 1 fig

Monitoring oak-hickory forest change during an unprecedented red oak borer outbreak in the Ozark Mountains: 1990 to 2006

Upland oak-hickory forests in Arkansas, Missouri, and Oklahoma experienced oak decline in the late 1990s and early 2000s during an unprecedented outbreak of a native beetle, the red oak borer (ROB), Enaphalodes rufulus (Haldeman). Although remote sensing supports frequent monitoring of continuously changing forests, comparable in situ observations are critical for developing an understanding of past and potential ROB damage in the Ozark Mountains. We categorized forest change using a normalized difference water index (NDWI) applied to multitemporal Landsat TM and ETM+ imagery (1990, 2001, and 2006). Levels of decline or growth were categorized using simple statistical thresholds of change in the NDWI over time. Corresponding decline and growth areas were then observed in situ where tree diameter, age, crown condition, and species composition were measured within variable radius plots. Using a machine learning decision tree classifier, remote sensing-derived decline and growth was characterized in terms of in situ observation. Plots with tree quadratic mean diameter at breast height ≥21.5 cm were categorized remotely as in severe decline. Landsat TM/ETM+-based NDWI derivatives reveal forest decline and regrowth in post-ROB outbreak surveys. Historical and future Landsat-based canopy change detection should be incorporated with existing landscape-based prediction of ROB hazard.

We found that high frequency of persistent herpes viruses usually occurs as associations with CMV, EBV and human herpes virus 6 type. We substantiated anti viral and immune corrective therapy in two schemes compared in efficacy: the 1st group was administered monotherapy with Viferon, and the 2nd group received combined therapy Viferon + Arbidol in doses according to the age during three months. We received a more expressed clinical immunologic effect from the therapy with decreased antigenic load and frequency of recurrence of RC and ROB with Viferon application in suppositories in combination with Arbidol per orally in the intermittent scheme during three months.

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. This work describes water absorption mechanisms of two expanded polymers (expanded polyurethane and expanded polystyrene, in various aqueous media (seawater and distilled water. The influence of the samples geometry on the water absorption kinetics was studied. The samples with a larger contact area with water were found to be more susceptible to water absorption

In this field, nanomaterials offer interesting antimicrobial properties (eg, long-lasting activity; intracellular and tissular penetration as compared to conventional products. The aim of this work was to produce, by a new solvent-free process, a stable and easily freeze-dryable chlorhexidine-loaded polymeric nanocapsule (CHX-NC suspension, and then to assess the antimicrobial properties of nanomaterials. The relevance of the process and the physicochemical properties of the CHX-NCs were examined by the assessment of encapsulation efficiency, stability of the nanomaterial suspension after 1 month of storage, and by analysis of granulometry and surface electric charge of nanocapsules. In vitro antimicrobial activities of the CHX-NCs and chlorhexidine digluconate solution were compared by measuring the inhibition diameters of two bacterial strains (Escherichia coli and Staphylococcus aureus and one fungal strain (Candida albicans cultured onto appropriate media. Based on the findings of this study, we report a new solvent-free process for the

2005-01-01

On the Compact Muon Solenoid (CMS) experimentat the Large Hadron Collider (LHC) at the CERN laboratory, the drift tube chambers are responsible for muon detection and precise momentum measurement. In this paper the first level of the read out electronics for these drift tube chambers is described. These drift tube chambers will be located inside the muon barrel detector in the so-called minicrates (MCs), attached to the chambers. The read out boards (ROBs) are the main component of this first level data acquisition system, and they are responsible for the time digitalization related to Level 1 Accept (L1A) trigger of the incoming signals from the front-end electronics, followed by a consequent data merging to the next stages of the data acquisition system. ROBs' architecture and functionality have been exhaustively tested, as well as their capability of operation beyond the expected environmental conditions inside the CMS detector. Due to the satisfactory results obtained, final production of ROBs and their a...

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

Replacing textbook problems with lab experiences

Science.gov (United States)

Register, Trevor

2017-10-01

End-of-the-chapter textbook problems are often the bread and butter of any traditional physics classroom. However, research strongly suggests that students be given the opportunity to apply their knowledge in multiple contexts as well as be provided with opportunities to do the process of science through laboratory experiences. Little correlation has been shown linking the number of textbook problems solved with conceptual understanding of topics in mechanics. Furthermore, textbook problems as the primary source of practice for students robs them of the joy and productive struggle of learning how to think like an experimental physicist. Methods such as Modeling Instruction tackle this problem head-on by starting each instructional unit with an inquiry-based lab aimed at establishing the important concepts and equations for the unit, and this article will discuss ideas and experiences for how to carry that philosophy throughout a unit.

Spatial and temporal trends in PCBs in sediment along the lower Rhone River, France

Despite increasingly strict control of polychlorinated biphenyl (PCB) releases in France since the mid-1970s, PCB contamination of fish recently has emerged as a major concern in the lower Rhone River basin. We measured PCB concentrations in Rhone sediment to evaluate the effects of PCB releases from major urban and industrial areas, sediment redistribution by large floods, and regulatory controls on PCB trends from 1970 to present. Profiles of PCBs (the sum of seven indicator PCB congeners) were reconstructed from sediment cores collected from an off-river rural reference site and from three depositional areas along the Rhone upstream and downstream from the city of Lyon, France. Core chronology was determined from radionuclide profiles and flood deposits. PCB concentrations increased progressively in the downstream direction, and reached a maximum concentration in 1991 of 281 μg/kg at the most downstream site. At the rural reference site and at the upstream Rhone site, PCB concentrations peaked in the 1970s (maximum concentration of 13 and 78 μg/kg, respectively) and have decreased exponentially since then. PCB concentrations in the middle and downstream cores were elevated into the early 1990s, decreased very rapidly until 2000, and since then have remained relatively stable. Congener profiles for three time windows (1965–80, 1986–93, and 2000–08) were similar in the three sediment cores from the Rhone and different from those at the rural reference site. The results indicate that permitted discharges from a hazardous-waste treatment facility upstream from Lyon might have contributed to high concentrations into the 1980-90s, but that industrial discharges from the greater Lyon area and tributaries to the Rhone near Lyon have had a greater contribution since the 1990s. There is little indication that PCB concentration in sediments downstream from Lyon will decrease over at least the short term.

Measurement of infiltration rates in urban sewer systems by use of oxygen isotopes.

Science.gov (United States)

De Bénédittis, J; Bertrand-Krajewski, J L

2005-01-01

The paper presents the principle of a method to measure infiltration rates in sewer systems based on the use of oxygen isotopes and its application in Lyon (France). In the urban area of Lyon, significant differences in delta 18O that can reach 3 per thousand are observed between the oxygen isotopic compositions of groundwater originating from Rhone, Saone and from their associated alluvial aquifers. Drinking water supplying Lyon results mainly from pumping in the Rhone alluvial aquifer. Therefore, in some areas, the difference of isotopic composition between wastewater resulting from the consumption of drinking water and local groundwater can be used to measure infiltration in sewer systems. The application in the catchment of Ecully shows that the infiltration flow rate presents strong fluctuations at an hourly scale: it varies between 15 and 40 m3/h. This variability could be explained by non-constant discharges of pumping and by variations of the water level in the sewer.

Pollinators shift to nectar robbers when florivory occurs, with effects on reproductive success in Iris bulleyana (Iridaceae).

Studies have indicated that florivory and nectar robbing may reduce reproductive success of host plants. However, whether and how these effects might interact when plants are simultaneously attacked by both florivores and nectar robbers still needs further investigation. We used Iris bulleyana to detect the interactions among florivory, nectar robbing and pollination, and moreover, their effects on plant reproductive success. Field investigations and hand-pollination treatments were conducted on two experimental plots from a natural population, in which Experimental plot was protected from florivores and Control plot was not manipulated. The flower calyx was bitten by sawflies to consume the nectary, and three bumblebee species were pollinators. In addition, the short-tongued pollinator, Bombus friseanus, was the only robber when there was a hole made by a sawfly. The bumblebee had significantly shortened flower handling time when robbing, as compared to legitimate visits. Pollinator visitation and seed production decreased significantly in damaged flowers. However, seed production per flower after supplementary hand-pollination did not differ significantly between damaged and undamaged flowers. Compared to the Experimental plot, bumblebees visited fewer flowers per plant in a foraging bout in the Control plot. The flowers damaged by florivory allowed B. friseanus to shift to a nectar robber. Florivory and nectar robbing collectively decreased plant reproductive success by consuming nectar resources, which may reduce attractiveness to pollinators of the damaged flowers. However, the changes in pollinator behaviour might be beneficial to the plant by reducing the risk of geitonogamous mating. © 2017 German Botanical Society and The Royal Botanical Society of the Netherlands.

Despite increasingly strict control of polychlorinated biphenyl (PCB) releases in France since the mid-1970s, PCB contamination of fish recently has emerged as a major concern in the lower Rhone River basin. We measured PCB concentrations in Rhone sediment to evaluate the effects of PCB releases from major urban and industrial areas, sediment redistribution by large floods, and regulatory controls on PCB trends from 1970 to present. Profiles of PCBs (the sum of seven indicator PCB congeners) were reconstructed from sediment cores collected from an off-river rural reference site and from three depositional areas along the Rhone upstream and downstream from the city of Lyon, France. Core chronology was determined from radionuclide profiles and flood deposits. PCB concentrations increased progressively in the downstream direction, and reached a maximum concentration in 1991 of 281 {mu}g/kg at the most downstream site. At the rural reference site and at the upstream Rhone site, PCB concentrations peaked in the 1970s (maximum concentration of 13 and 78 {mu}g/kg, respectively) and have decreased exponentially since then. PCB concentrations in the middle and downstream cores were elevated into the early 1990s, decreased very rapidly until 2000, and since then have remained relatively stable. Congener profiles for three time windows (1965-80, 1986-93, and 2000-08) were similar in the three sediment cores from the Rhone and different from those at the rural reference site. The results indicate that permitted discharges from a hazardous-waste treatment facility upstream from Lyon might have contributed to high concentrations into the 1980-90s, but that industrial discharges from the greater Lyon area and tributaries to the Rhone near Lyon have had a greater contribution since the 1990s. There is little indication that PCB concentration in sediments downstream from Lyon will decrease over at least the short term. -- Highlights: Black-Right-Pointing-Pointer We reconstructed

ompW is cooperatively upregulated by MarA and SoxS in response to menadione.

Science.gov (United States)

Collao, B; Morales, E H; Gil, F; Calderón, I L; Saavedra, C P

2013-04-01

OmpW is a minor porin whose biological function has not been clearly defined. Evidence obtained in our laboratory indicates that in Salmonella enterica serovar Typhimurium the expression of OmpW is activated by SoxS upon exposure to paraquat and it is required for resistance. SoxS belongs to the AraC family of transcriptional regulators, like MarA and Rob. Due to their high structural similarity, the genes under their control have been grouped in the mar/sox/rob regulon, which presents a DNA-binding consensus sequence denominated the marsox box. In this work, we evaluated the role of the transcription factors MarA, SoxS and Rob of S. enterica serovar Typhimurium in regulating ompW expression in response to menadione. We determined the transcript and protein levels of OmpW in different genetic backgrounds; in the wild-type and Δrob strains ompW was upregulated in response to menadione, while in the ΔmarA and ΔsoxS strains the induction was abolished. In a double marA soxS mutant, ompW transcript levels were lowered after exposure to menadione, and only complementation in trans with both genes restored the positive regulation. Using transcriptional fusions and electrophoretic mobility shift assays with mutant versions of the promoter region we demonstrated that two of the predicted sites were functional. Additionally, we demonstrated that MarA increases the affinity of SoxS for the ompW promoter region. In conclusion, our study shows that ompW is upregulated in response to menadione in a cooperative manner by MarA and SoxS through a direct interaction with the promoter region.

Full Text Available Chicken essence (CE is a popular traditional remedy in Asia, which is believed to improve cognitive functions. CE company claimed that the health benefits were proven with research studies. A systematic review was conducted to determine the cognitive-enhancing effects of CE. We systematically searched a number of databases for randomized controlled trials with human subjects consuming CE and cognitive tests involved. Cochrane’s Risk of Bias (ROB tool was used to assess the quality of trials and meta-analysis was performed. Seven trials were included, where six healthy subjects and one subject with poorer cognitive functions were recruited. One trial had unclear ROB while the rest had high ROB. For executive function tests, there was a significant difference favoring CE (pooled standardized mean difference (SMD of −0.55 (−1.04, −0.06 and another with no significant difference (pooled SMD of 0.70 (−0.001, 1.40. For short-term memory tests, no significant difference was found (pooled SMD of 0.63 (−0.16, 1.42. Currently, there is a lack of convincing evidence to show a cognitive enhancing effect of CE.

The TDAQ Baseline Architecture

The Trigger-DAQ community is currently busy preparing material for the DAQ, HLT and DCS TDR. Over the last few weeks a very important step has been a series of meetings to complete agreement on the baseline architecture. An overview of the architecture indicating some of the main parameters is shown in figure 1. As reported at the ATLAS Plenary during the February ATLAS week, the main area where the baseline had not yet been agreed was around the Read-Out System (ROS) and details in the DataFlow. The agreed architecture has: Read-Out Links (ROLs) from the RODs using S-Link; Read-Out Buffers (ROB) sited near the RODs, mounted in a chassis - today assumed to be a PC, using PCI bus at least for configuration, control and monitoring. The baseline assumes data aggregation, in the ROB and/or at the output (which could either be over a bus or in the network). Optimization of the data aggregation will be made in the coming months, but the current model has each ROB card receiving input from 4 ROLs, and 3 such c...

The code RobSim has been added to RobWin.1 It simulates spectra resulting from gamma rays striking an array of detectors made up of different components. These are frequently used to set coincidence and anti-coincidence windows that decide if individual events are part of the signal. The first problem addressed is the construction of the detector. Then owing to the statistical nature of the responses of these elements there is a random nature in the response that can be taken into account by including fractional counts in the output spectrum. This somewhat complicates the error analysis, as Poisson statistics are no longer applicable

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

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...

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.

With the beginning of the 24th Solar cycle, the increased Solar activity requires having a close eye on the ionosphere for better understanding Space Weather physics and its effects on radio communications. In that frame, near-real time ionospheric models over Europe are now routinely generated at the Royal Observatory of Belgium (ROB). These models are made available to the public through new interactive web pages at the web site of the GNSS team (www.gnss.be) and the Solar Influences Data Analysis Center (www.sidc.be) of ROB. The models are ionospheric Vertical Total Electron Content (VTEC) maps estimated every 15 minutes on a 0.5°x0.5° grid. They use the high-rate GPS observations of the real-time stations in the EUREF Permanent Network (EPN) provided by the ROB NTRIP broadcaster. The maps are published on the ROB web site with a latency of 7-15 minutes with respect to the last GPS measurement included in the 15-minute observation files. In a first step, this paper presents the processing strategy used to generate the VTEC maps: input data, parameter estimation, data cleaning and interpolation method. In addition, the tools developed to further exploit the product are introduced, e.g. on-demand animated VTEC maps. In a second step, the VTEC maps are compared with external ionospheric products and models such as Global Ionospheric Maps and IRI 2011. These new near-real time VTEC maps will allow any user within the geographical scope of the maps to estimate in near-real time the ionospheric delay induced along the signal of any observed satellite. In the future, the web site will continuously be updated in response to evolving user needs. This paper opens doors to discussions with the user community to target their needs.

Changes in gene dosage are a major driver of cancer, known to be caused by a finite, but increasingly well annotated, repertoire of mutational mechanisms. This can potentially generate correlated copy-number alterations across hundreds of linked genes, as exemplified by the 2% of childhood acute lymphoblastic leukaemia (ALL) with recurrent amplification of megabase regions of chromosome 21 (iAMP21). We used genomic, cytogenetic and transcriptional analysis, coupled with novel bioinformatic approaches, to reconstruct the evolution of iAMP21 ALL. Here we show that individuals born with the rare constitutional Robertsonian translocation between chromosomes 15 and 21, rob(15;21)(q10;q10)c, have approximately 2,700-fold increased risk of developing iAMP21 ALL compared to the general population. In such cases, amplification is initiated by a chromothripsis event involving both sister chromatids of the Robertsonian chromosome, a novel mechanism for cancer predisposition. In sporadic iAMP21, breakage-fusion-bridge cycles are typically the initiating event, often followed by chromothripsis. In both sporadic and rob(15;21)c-associated iAMP21, the final stages frequently involve duplications of the entire abnormal chromosome. The end-product is a derivative of chromosome 21 or the rob(15;21)c chromosome with gene dosage optimized for leukaemic potential, showing constrained copy-number levels over multiple linked genes. Thus, dicentric chromosomes may be an important precipitant of chromothripsis, as we show rob(15;21)c to be constitutionally dicentric and breakage-fusion-bridge cycles generate dicentric chromosomes somatically. Furthermore, our data illustrate that several cancer-specific mutational processes, applied sequentially, can coordinate to fashion copy-number profiles over large genomic scales, incrementally refining the fitness benefits of aggregated gene dosage changes.

More than 230 randomized controlled trials (RCTs) of danshen dripping pill (DSP) and isosorbide dinitrate (ISDN) in treating angina pectoris after the first preferred reporting items for systematic reviews and meta-analyses-compliant comprehensive meta-analysis were published in 2010. Other meta-analyses had flaws in study selection, statistical meta-analysis, and evidence assessment. This study completed the meta-analysis with an extensive assessment of the evidence. RCTs published from 1994 to 2016 on DSP and ISDN in treating angina pectoris for at least 4 weeks were included. The risk of bias (RoB) of included RCTs was assessed with the Cochrane's tool for assessing RoB. Meta-analyses based on a random-effects model were performed on two outcome measures: symptomatic (SYM) and electrocardiography (ECG) improvements. Subgroup analysis, sensitivity analysis, metaregression, and publication bias analysis were also conducted. The evidence strength was evaluated with the Grades of Recommendation, Assessment, Development, and Evaluation (GRADE) method. Among the included 109 RCTs with 11,973 participants, 49 RCTs and 5042 participants were new (after 2010). The RoB of included RCTs was high in randomization and blinding. Overall effect sizes in odds ratios for DSP over ISDN were 2.94 (95% confidence interval [CI]: 2.53-3.41) on SYM (n = 108) and 2.37 (95% CI: 2.08-2.69) by ECG (n = 81) with significant heterogeneities (I 2  = 41%, p < 0.0001 on SYM and I 2  = 44%, p < 0.0001 on ECG). Subgroup, sensitivity, and metaregression analyses showed consistent results without publication bias. However, the evidence strength was low in GRADE. The efficacy of DSP was still better than ISDN in treating angina pectoris, but the confidence decreased due to high RoB and heterogeneities.

Cornell product criteria, Sokolow-Lyon voltage criteria and electrocardiographic (ECG) strain (secondary ST-T abnormalities) are markers for left ventricular hypertrophy (LVH) and adverse prognosis in population studies. However, the relationship of regression of ECG LVH and strain during antihypertensive therapy to cardiovascular (CV) risk was unclear before the Losartan Intervention for Endpoint Reduction in Hypertension (LIFE) study. We reviewed findings on ECG LVH regression and strain over time in 9193 hypertensive patients with ECG LVH at baseline enrolled in the LIFE study. The composite endpoint of CV death, nonfatal MI, or stroke occurred in 1096 patients during 4.8±0.9years follow-up. In Cox multivariable models adjusting for randomized treatment, known risk factors including in-treatment blood pressure, and for severity ECG LVH by Cornell product and Sokolow-Lyon voltage, baseline ECG strain was associated with a 33% higher risk of the LIFE composite endpoint (HR. 1.33, 95% CI [1.11-1.59]). Development of new ECG strain between baseline and year-1 was associated with a 2-fold increased risk of the composite endpoint (HR. 2.05, 95% CI [1.51-2.78]), whereas the risk associated with regression or persistence of ECG strain was attenuated and no longer statistically significant (both p>0.05). After controlling for treatment with losartan or atenolol, for baseline Framingham risk score, Cornell product, and Sokolow-Lyon voltage, and for baseline and in-treatment systolic and diastolic blood pressure, 1 standard deviation (SD) lower in-treatment Cornell product was associated with a 14.5% decrease in the composite endpoint (HR. 0.86, 95% CI [0.82-0.90]). In a parallel analysis, 1 SD lower in-treatment Sokolow-Lyon voltage was associated with a 16.6% decrease in the composite endpoint (HR. 0.83, 95% CI [0.78-0.88]). The LIFE study shows that evaluation of both baseline and in-study ECG LVH defined by Cornell product criteria, Sokolow-Lyon voltage criteria or

PER has been evaluated in three pivotal placebo-controlled randomized trials as adjunctive therapy in adult drug-resistant partial epilepsy. In comparison to placebo, adjunctive PER effectively reduces seizure frequency. The relative risk of the responder rate (95% confidence interval [CI] was thus 1.60 (1.08–2.36, 1.79 (1.42–2.25 and 1.66 (1.24–2.23 for once-daily PER 4 mg/day, 8 mg/day and 12 mg/day, respectively. The most common adverse events associated with PER were nonspecific central nervous system side effects. Some concerns have been raised about risk of clinically significant weight gain and of psychiatric adverse events. Long-term open-label extensions of the three pivotal trials are underway. PER has recently been approved both in Europe and in the USA for the adjunctive treatment of partial onset seizures in patients aged 12 years and above. However, in the absence of a direct comparison between PER and other licensed antiepileptic drugs’ efficacy and tolerability, the clinical advantages of PER over the other drugs in intractable partial epilepsy remains to be determined.Keywords: perampanel, epilepsy, antiepileptic drug, partial seizures

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.

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.

Approved by the Food and Drug Administration in 2009 in the United States for the treatment of metastatic renal cell carcinoma, pazopanib has been tested in advanced or metastatic soft-tissue sarcoma. Unlike other tyrosine kinase inhibitors, a statistically significant efficacy in phase II but also in randomized phase III studies has been shown. In comparison with sunitinib or sorafenib, pazopanib has a similar toxicity profile and is generally well tolerated. This review details the development of this new therapeutic class in the treatment of metastatic soft-tissue sarcomas.Keywords: soft-tissue sarcoma, pazopanib, tyrosine kinase inhibitor

In adolescent athletes, low back pain has a 1-year prevalence of 57% and causes include spondylolysis and spondylolisthesis. An accurate diagnosis enables healing, prevention of progression and return to sport. To evaluate the diagnostic utility of patient history and physical examination data to identify spondylolysis and/or spondylolisthesis in athletes. Systematic review was undertaken according to published guidelines, and reported in line with PRISMA. Key databases were searched up to 13/11/15. athletic population with LBP, patient history and/or physical examination accuracy data for spondylolysis and/or spondylolisthesis, any study design including raw data. Two reviewers independently assessed risk of bias (ROB) using QUADAS-2. A data extraction sheet was pre-designed. Pooling of data and investigation for heterogeneity enabled a qualitative synthesis of data across studies. Of the eight included studies, two were assessed as low ROB, one of which also had no concerns regarding applicability. Age (75% for spondylolisthesis. Step-deformity palpation demonstrated 60-88% sensitivity and 87-100% specificity for spondylolisthesis. The one-legged hyperextension test was not supported for spondylolysis (sensitivity 50-73%, specificity 0-87%). No recommendations can be made utilising patient history data. Based on one low ROB study, step deformity palpation may be useful in diagnosing spondylolisthesis. No physical tests demonstrated diagnostic utility for spondylolysis. Further research is required.

Meadley Dunphy, Shannon A; Prior, Kirsten M; Frederickson, Megan E

2016-05-01

Plant-animal mutualisms, such as seed dispersal, are often vulnerable to disruption by invasive species. Here, we show for the first time how a non-ant invasive species negatively affects seed dispersal by ants. We examined the effects of several animal species that co-occur in a temperate deciduous forest-including native and invasive seed-dispersing ants (Aphaenogaster rudis and Myrmica rubra, respectively), an invasive slug (Arion subfuscus), and native rodents-on a native myrmecochorous plant, Asarum canadense. We experimentally manipulated ant, slug, and rodent access to seed depots and measured seed removal. We also video-recorded depots to determine which other taxa interact with seeds. We found that A. rudis was the main disperser of seeds and that A. subfuscus consumed elaiosomes without dispersing seeds. Rodent visitation was rare, and rodent exclusion had no significant effect on seed or elaiosome removal. We then used data obtained from laboratory and field mesocosm experiments to determine how elaiosome robbing by A. subfuscus affects seed dispersal by A. rudis and M. rubra. We found that elaiosome robbing by slugs reduced seed dispersal by ants, especially in mesocosms with A. rudis, which picks up seeds more slowly than M. rubra. Taken together, our results show that elaiosome robbing by an invasive slug reduces seed dispersal by ants, suggesting that invasive slugs can have profound negative effects on seed dispersal mutualisms.

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.

The effect of restored and native oxbows on hydraulic loads of nutrients and stream water quality

Science.gov (United States)

Kalkhoff, Stephen J.; Hubbard, Laura E.; Joseph P.Schubauer-Berigan,

2016-01-01

The use of oxbow wetlands has been identified as a potential strategy to reduce nutrient transport from agricultural drainage tiles to streams in Iowa. In 2013 and 2014, a study was conducted in north-central Iowa in a native oxbow in the Lyons Creek watershed and two restored oxbow wetlands in the Prairie Creek watershed (Smeltzer west and Smeltzer east) to assess their effectiveness at reducing nitrogen and phosphorus loads. The tile line inlets carrying agricultural runoff to the oxbows, the outfall from the oxbows, and the surface waters in the streams receiving the outfall water were monitored for discharge and nutrients from February 2013 to September 2015. Smeltzer west and east also had four monitoring wells each, two in the upland and two between the oxbow and Prairie Creek to monitor surface water-groundwater interaction. The Smeltzer west and east oxbow sites also were instrumented to continuously measure the nitrate concentration. Rainfall was measured at one Lyons Creek and one Smeltzer site. Daily mean nitrate-N concentrations in Lyons Creek in 2013 ranged from 11.8 mg/L to 40.9 mg/L, the median daily mean nitrate-N concentration was 33.0 mg/L. Daily mean nitrate-N concentrations in Prairie Creek in 2013 ranged from 0.07 mg/L in August to 32.2 mg/L in June. In 2014, daily mean nitrate-N concentrations in Prairie Creek ranged from 0.17 mg/L in April to 26.7 mg/L in July; the daily mean nitrate-N concentration for the sampled period was 9.78 mg/L. Nutrient load reduction occurred in oxbow wetlands in Lyons and Prairie Creek watersheds in north-central Iowa but efficiency of reduction was variable. Little nutrient reduction occurred in the native Lyons Creek oxbow during 2013. Concentrations of all nutrient constituents were not significantly (P>0.05, Wilcoxon rank sum) different in water discharging from the tile line than in water leaving the Lyons Creek oxbow. A combination of physical features and flow conditions suggest that the residence time of

Students enabling students in a Student Partnership Project: A case study emerging from the OLT Transforming Practice Project on Student Partnerships

Directory of Open Access Journals (Sweden)

Megan Kek

2017-07-01

Full Text Available This emerging initiative stemmed from an Office for Learning and Teaching Project (OLT project, Transforming Practice Programme 2016: Student Engagement: Students as Partners in Teaching and Learning. The initiative, trialed in semester two, 2016, involved the selection and training of two experienced students to be leaders of a Closed Facebook ‘students-only’ community which provided advice and triaged queries to appropriate channels. The evaluative processes comprised a participatory action research methodology. Two student leaders who facilitated the Closed Facebook and four academic staff of the project were the participants. The findings demonstrate that the Closed Facebook students-only site provided a safe space, outside the formal learning/classroom environment, where student participants were able to ask and share knowledge. The informal student-for-student learning community complemented the formal structure by facilitating the opportunity for students to become ‘experts’ as university students as they move-through their learning journey.

Biologically inspired emotion recognition from speech

Buscicchio Cosimo

2011-01-01

Full Text Available Abstract Emotion recognition has become a fundamental task in human-computer interaction systems. In this article, we propose an emotion recognition approach based on biologically inspired methods. Specifically, emotion classification is performed using a long short-term memory (LSTM recurrent neural network which is able to recognize long-range dependencies between successive temporal patterns. We propose to represent data using features derived from two different models: mel-frequency cepstral coefficients (MFCC and the Lyon cochlear model. In the experimental phase, results obtained from the LSTM network and the two different feature sets are compared, showing that features derived from the Lyon cochlear model give better recognition results in comparison with those obtained with the traditional MFCC representation.

The ATLAS Metadata Interface (AMI) can be considered to be a mature application because it has existed for at least 10 years. Over the years, the number of users and the number of functions provided for these users has increased. It has been necessary to adapt the hardware infrastructure in a seamless way so that the Quality of Service remains high. We will describe the evolution of the application from the initial one, using single server with a MySQL backend database, to the current state, where we use a cluster of Virtual Machines on the French Tier 1 Cloud at Lyon, an ORACLE database backend also at Lyon, with replication to CERN using ORACLE streams behind a back-up server.

Global health education is becoming more important for developing well-rounded physicians and may encourage students toward a career in primary care. Many medical schools, however, lack adequate and structured opportunities for students beginning the curriculum. Second-year medical students initiated, designed, and facilitated a pass-fail international health elective, providing a curricular framework for preclinical medical students wishing to gain exposure to the clinical and cultural practices of a developing country. All course participants (N=30) completed a post-travel questionnaire within one week of sharing their experiences. Screening reflection essays for common themes that fulfill university core competencies yielded specific global health learning outcomes, including analysis of health care determinants. Medical students successfully implemented a sustainable global health curriculum for preclinical student peers. Financial constraints, language, and organizational burdens limit student participation. In future, long-term studies should analyze career impact and benefits to the host country.

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.

The Perceptions of Elementary School Teachers Regarding Their Efforts to Help Students Utilize Student-to-Student Discourse in Science

Science.gov (United States)

Craddock, Jennifer Lovejoy

The purpose of this phenomenological study was to examine the perceptions of elementary teachers who teach science as opposed to science teacher specialists regarding their efforts to help students use student-to-student discourse for improving science learning. A growing body of research confirms the importance of a) student-to-student discourse for making meaning of science ideas and b) moving students' conceptual development towards a more scientific understanding of the natural world. Based on those foundations, the three research questions that guided this study examined the value elementary teachers place on student-to-student discourse, the various approaches teachers employ to promote the use of student-to-student discourse for learning science, and the factors and conditions that promote and inhibit the use of student-to-student discourse as an effective pedagogical strategy in elementary science. Data were gathered from 23 elementary teachers in a single district using an on-line survey and follow-up interviews with 8 teachers. All data were analyzed and evolving themes led to the following findings: (1) elementary teachers value student-to-student discourse in science, (2) teachers desire to increase time using student-to-student discourse, (3) teachers use a limited number of student-to-student discourse strategies to increase student learning in science, (4) teachers use student-to-student discourse as formative assessment to determine student learning in science, (5) professional development focusing on approaches to student-to-student discourse develops teachers' capacity for effective implementation, (6) teachers perceive school administrators' knowledge of and support for student-to-student discourse as beneficial, (7) time and scheduling constraints limit the use of student-to-student discourse in science. Implications of this study included the necessity of school districts to focus on student-to-student discourse in science, provide teacher and

Solar Heliospheric and INterplanetary Environment (SHINE) Students - Student Representatives' Perspectives

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.

Determinants and improvement of electrocardiographic diagnosis of left ventricular hypertrophy in a black African population.

Directory of Open Access Journals (Sweden)

Ahmadou M Jingi

Full Text Available BACKGROUND: Left ventricular hypertrophy (LVH is a major cardiovascular risk factor. The electrocardiogram (ECG has been shown to be a poor tool in detecting LVH due to cardiac and extracardiac factors. We studied the determinants and possibility of improving the test performance of the ECG in a group of Black Africans. METHODS: We studied echocardiograms and electrocardiograms of 182 Cameroonian patients among whom 113 (62.1% were having an echocardiographic LVH. Echocardiographic LVH was defined as Left Ventricular Mass Indexed to height 2.7(LVMI>48 g/m2.7 in men, and >44 g/m 2.7 in women or Body Surface Area ≥116 g/m2 in men, and ≥96 g/m2 in women. Test performances were calculated for 6 classic ECG criteria Sokolow-Lyon, Cornell, Cornell product, Gubner-Ungerleiger, amplitudes of R in aVL, V5 and V6. RESULTS: The most sensitive criteria were Cornell (37.2% and Sokolow-Lyon index (26.5%. The most specific criteria were Gubner (98.6%, RaVL (97.1%, RV5/V6 (95.7% and Cornell product (94.2%. The performance of the ECG in diagnosing LVH significantly increased with the severity of LVH for Cornell index (r = 0.420, p<0.0001 and Sokolow index (r = 0.212, p = 0.002. It decreased with body habitus (r = -0.248, p = 0.001 for Sokolow-Lyon index. Cornell index was less affected (age p = 0.766; body habitus: p = 0.209. After sex-specific adjustment for BMI, Cornell BMI sensitivity increased from 37.2% to 69% (r = 0.472, p<0.0001, and Sokolow-Lyon BMI sensitivity increased from 26.5% to 58.4% (r = 0.270, p<0.001. CONCLUSION: The test performance of the ECG in diagnosing LVH is low in this Black African population, due to extracardiac factors such as age, sex, body habitus, and cardiac factors such as LVH severity and geometry. However, this performance is improved after adjustment for extracardiac factors.

Full Text Available This study examines the potential effect of scaffolding-based instruction and portfolio-based assessment on Jordanian EFL tenth grade students’ overall writing performance and their performance on the sub-skills of focus, development, organization, conventions and word choice. The study uses a quasi-experimental experimental/control group, pre-/posttest design. In the experimental group, 15 female tenth grade students from the North-Eastern Badia Directorate of Education (Jordan were taught to generate ideas, structure, draft, and edit their written pieces using agency scaffolding, the scaffolding principles of contextual support, continuity, intersubjectivity, flow, contingency and handover, and a slightly adapted version of Hamp-Lyons and Condon’s (2000 Portfolio Model of collection, selection and reflection. A control group of 28 students were instructed conventionally per the guidelines of the teacher’s book. Using descriptive statistics and ANCOVA to analyze the students’ scores on the pre- and the posttests, the results showed that the group taught through scaffolding-based instruction and portfolio-based assessment outperformed the control group (at a≤ 0.05 in their overall writing performance and in their performance on the five writing sub-skills.

Full Text Available Evidence of an adverse influence of soil transmitted helminth (STH infections on cognitive function and educational loss is equivocal. Prior meta-analyses have focused on randomized controlled trials only and have not sufficiently explored the potential for disparate influence of STH infection by cognitive domain. We re-examine the hypothesis that STH infection is associated with cognitive deficit and educational loss using data from all primary epidemiologic studies published between 1992 and 2016.Medline, Biosis and Web of Science were searched for original studies published in the English language. Cognitive function was defined in four domains (learning, memory, reaction time and innate intelligence and educational loss in two domains (attendance and scholastic achievement. Pooled effect across studies were calculated as standardized mean differences (SMD to compare cognitive and educational measures for STH infected/non-dewormed children versus STH uninfected /dewormed children using Review Manager 5.3. Sub-group analyses were implemented by study design, risk of bias (ROB and co-prevalence of Schistosoma species infection. Influential studies were excluded in sensitivity analysis to examine stability of pooled estimates.We included 36 studies of 12,920 children. STH infected/non-dewormed children had small to moderate deficits in three domains-learning, memory and intelligence (SMD: -0.44 to -0.27, P<0.01-0.03 compared to STH-uninfected/dewormed children. There were no differences by infection/treatment status for reaction time, school attendance and scholastic achievement (SMD: -0.26 to -0.16, P = 0.06-0.19. Heterogeneity of the pooled effects in all six domains was high (P<0.01; I2 = 66-99%. Application of outlier treatment reduced heterogeneity in learning domain (P = 0.12; I2 = 33% and strengthened STH-related associations in all domains but intelligence (SMD: -0.20, P = 0.09.

In the last years research on the didactics of Psychiatry and opinions of medical students on Psychiatry has gained great interest. The authors think that this research could be useful for the improvement of didactics, for better understanding the meanings of professional choice, the identity of psychiatrist and their relationship with colleagues in other medical field. The goal of this research work was a preliminary survey of Genoese University Medical Student's opinions about psychiatry didactics, and choice of specialization. A questionnaire was submitted to all the students who passed Clinical Psychiatry examination in the period from November 1987 to December 1988. The students were divided in two randomized groups: the first group of students (224) was submitted to the questionnaire immediately after Clinical Psychiatry examination; while to the second group of students (66) the questionnaire was mailed. The aim of the questions was to assess the student's opinions on psychiatry, psychoanalysis, psychotherapy, the career they wanted to take up, and the difficulties of studying psychiatry: 69% of the students of the first group and 42% of the students of the second group answered the questionnaire. Female students answered that they preferred psychiatric specialization more than their male colleagues did, but the difference has no statistical importance. In most cases, the students who answered that they have taken into account psychiatry as a choice of specialisation, are more interested in medical specialties (primary care, etc.) than in surgical specialties. Most of the medical students declare some emotional troubles (anxiety, sleeplessness, problem in social relations).(ABSTRACT TRUNCATED AT 250 WORDS)

Early school withdrawal, commonly referred to as dropout, is associated with a plethora of negative outcomes for students, schools, and society. Student engagement, however, presents as a promising theoretical model and cornerstone of school completion interventions. The purpose of the present study was to validate the Student Engagement Instrument-Elementary Version (SEI-E). The psychometric properties of this measure were assessed based on the responses of an ethnically diverse sample of 1,943 students from an urban locale. Exploratory and confirmatory factor analyses indicated that the 4-factor model of student engagement provided the best fit for the current data, which is divergent from previous SEI studies suggesting 5- and 6-factor models. Discussion and implications of these findings are presented in the context of student engagement and dropout prevention. (PsycINFO Database Record (c) 2012 APA, all rights reserved).

By means of meta-analysis of information from all relevant epidemiologic studies, we examined the hypothesis that Schistosoma infection in school-aged children (SAC) is associated with educational loss and cognitive deficits. This review was prospectively registered in the PROSPERO database (CRD42016040052). Medline, Biosis, and Web of Science were searched for studies published before August 2016 that evaluated associations between Schistosoma infection and cognitive or educational outcomes. Cognitive function was defined in four domains-learning, memory, reaction time, and innate intelligence. Educational outcome measures were defined as attendance and scholastic achievement. Risk of bias (ROB) was evaluated using the Newcastle-Ottawa quality assessment scale. Standardized mean differences (SMD) and 95% confidence intervals (CI) were calculated to compare cognitive and educational measures for Schistosoma infected /not dewormed vs. uninfected/dewormed children. Sensitivity analyses by study design, ROB, and sequential exclusion of individual studies were implemented. Thirty studies from 14 countries, including 38,992 SAC between 5-19 years old, were identified. Compared to uninfected children and children dewormed with praziquantel, the presence of Schistosoma infection and/or non-dewormed status was associated with deficits in school attendance (SMD = -0.36, 95%CI: -0.60, -0.12), scholastic achievement (SMD = -0.58, 95%CI: -0.96, -0.20), learning (SMD = -0.39, 95%CI: -0.70, -0.09) and memory (SMD = -0.28, 95%CI: -0.52, -0.04) tests. By contrast, Schistosoma-infected/non-dewormed and uninfected/dewormed children were similar with respect to performance in tests of reaction time (SMD = -0.06, 95%CI: -0.42, 0.30) and intelligence (SMD = -0.25, 95%CI: -0.57, 0.06).

Student Motivation in Science Subjects in Tanzania, Including Students' Voices

Science.gov (United States)

Mkimbili, Selina Thomas; Ødegaard, Marianne

2017-12-01

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.

Purpose Effective clinical leadership is crucial to avoid failings in the delivery of safe health care, particularly during a period of increasing scrutiny and cost-constraints for the National Health Service (NHS). However, there is a paucity of leadership training for health-care students, the future leaders of the NHS, which is due in part to overfilled curricula. The purpose of this study was to assess the impact of student-led leadership training for the benefit of fellow students. Design/methodology/approach To address this training gap, a group of multiprofessional students organised a series of large-group seminars and small-group workshops given by notable health-care leaders at a London university over the course of two consecutive years. Findings The majority of students had not previously received any formal exposure to leadership training. Feedback post-events were almost universally positive, though students expressed a preference for experiential teaching of leadership. Working with university faculty, an inaugural essay prize was founded and student members were given the opportunity to complete internships in real-life quality improvement projects. Originality/value Student-led teaching interventions in leadership can help to fill an unmet teaching need and help to better equip the next generation of health-care workers for future roles as leaders within the NHS.

A viable on-chip FPGA configuration memory scrubbing approach for CBM-ToF

Oancea, Andrei-Dumitru; Stuellein, Christian; Manz, Sebastian; Gebelein, Jano; Kebschull, Udo [Infrastruktur und Rechnersysteme in der Informationsverarbeitung (IRI), Goethe-Universitaet, Senckenberganlage 31, 60325 Frankfurt am Main (Germany); Collaboration: CBM-Collaboration

2015-07-01

The ToF Detector of the CBM Experiment will be equipped with FPGA-based read-out boards (ROBs). These ROBs will be operated in a radiation environment, and therefore need a mitigation mechanism against soft errors in the SRAM-based configuration memories of the FPGAs. The proposed approach combines intrinsic on-chip single upset correction with extrinsic selective frame scrubbing for multiple-bit upsets. The slow control is realized using the GBT-SCA, which is capable of handling interrupts. This enables the new approach of event-driven configuration frame correction. While conventional blind scrubbing leads to a continuous load on the control path, the selective frame scrubbing reduces this load to a minimum. For verification purposes, radiation tests with a proton beam were performed at COSY, Juelich. The occurred soft errors were classified into single and multiple- bit upsets, enabling an estimation of the rate at which extrinsic intervention is necessary.

'Patrimonialization' of contemporary scientific objects and their contexts of using: the Cockcroft-Walton particle accelerator

2016-01-01

Our thesis in science education explore the potentiality of contemporary scientific objects to become objects of heritage through a study case: the Cockcroft-Walton particle accelerator (CW). We call it 'patrimonialization' (the making of heritage) according to Information and Communication Sciences. We assume that the value of contemporary scientific objects, an important stage of the patrimonialization, is specific and requires a particular expertise. Our work was realized thanks to a french financing facility, allowing us to work with Le Musee des Confluences in Lyon (France), which exposes a particle accelerator CW in Societies: the human theater. The Institute of Lyon Nuclear physics (IPNL) also possesses a device of this type, who is the focus of a recognition project. sing a multidisciplinary approach, our analysis begin with a study of historical, epistemological, social and scientific context, of the first one CW. We also led two inquiries, the first one to redraw the accelerator CW trajectory in Lyon, the second to find all the accelerators CW in the world. Several studies have indeed highlighted the stages of the patrimonialization. Relying on these studies we characterized the specificities of the contemporary scientific heritage, and looked for tracks left by these characteristics in the exhibition text (museography). Our results demonstrate the lack of information allowing the interpretation (lecture) and the appropriation of the accelerator CW by a public, and invite us to question the representational contents of the object, conveyed through other contexts of use, formal or fictional.

It is man’s ongoing hope that a machine could somehow adapt to its environment by reorganizing itself. This is what the notion of self-organizing robots is based on. The theme of this book is to examine the feasibility of creating such robots within the limitations of current mechanical engineering. The topics comprise the following aspects of such a pursuit: the philosophy of design of self-organizing mechanical systems; self-organization in biological systems; the history of self-organizing mechanical systems; a case study of a self-assembling/self-repairing system as an autonomous distributed system; a self-organizing robot that can create its own shape and robotic motion; implementation and instrumentation of self-organizing robots; and the future of self-organizing robots. All topics are illustrated with many up-to-date examples, including those from the authors’ own work. The book does not require advanced knowledge of mathematics to be understood, and will be of great benefit to students in the rob...

Osborne, Michael A; Fogarty, Richard S

2012-01-01

In interwar France the Lyonnais physician Marius Piéry undertook an ambitious Neo-Hippocratic research program to study how atmospheric and terrestrial environments influenced health. Lyon had a number of institutions linked to the colonies and was a center for the training of military physicians. Colonial physicians had a long tradition of contending with the diseases of tropical environments, and their ideas and many returned colonials circulated in Lyon and its region. Piéry was a physician during World War I and published on military medical topics. He also included colonial and military health concerns in his more mature works from the 1930s. An advocate of the close study of the physical sciences, he investigated the radioactive gases of health spas and the effects of altitude on pulmonary tuberculosis, and he directed a meteorological observatory.

The laryngeal chemoreflex (LCR) induces apnea, glottis closure, bradycardia and hypertension in young and maturing mammals. We examined the distribution of medullary nuclei that are activated by the LCR and used immunofluorescent detection of Fos protein as a cellular marker for neuronal activation to establish that the medullary catecholaminergic and serotoninergic neurons participate in the modulation of the LCR. The LCR was elicited by the infusion of KCl-HCl solution into the laryngeal lumen of adult rats in the experimental group, whereas the control group received the same surgery but no infusion. In comparison, the number of regions of Fos-like immunoreactivity (FLI) that were activated by the LCR significantly increased in the nucleus of the solitary tract (NTS), the vestibular nuclear complex (VNC), the loose formation of the nucleus ambiguus (AmbL), the rostral ventral respiratory group (RVRG), the ventrolateral reticular complex (VLR), the pre-Bötzinger complex (PrBöt), the Bötzinger complex (Böt), the spinal trigeminal nucleus (SP5), and the raphe obscurus nucleus (ROb) bilaterally from the medulla oblongata. Furthermore, 12.71% of neurons with FLI in the dorsolateral part of the nucleus of the solitary tract (SolDL) showed tyrosine hydroxylase-immunoreactivity (TH-ir, catecholaminergic), and 70.87% of neurons with FLI in the ROb were serotoninergic. Our data demonstrated the distribution of medullary nuclei that were activated by the LCR, and further demonstrated that catecholaminergic neurons of the SolDL and serotoninergic neurons of the ROb were activated by the LCR, indicating the potential central pathway of the LCR.

Students have a low mathematical ability because they are used to learning to hear the teacher's explanation. For that students are given activities to sharpen his ability in math. One way to do that is to create discovery learning based work sheet. The development of this worksheet took into account specific student learning styles including in schools that have classified students based on multiple intelligences. The dominant learning styles in the classroom were intrapersonal and interpersonal. The purpose of this study was to discover students’ responses to the mathematics work sheets of the junior high school with a discovery learning approach suitable for students with Intrapersonal and Interpersonal Intelligence. This tool was developed using a development model adapted from the Plomp model. The development process of this tools consists of 3 phases: front-end analysis/preliminary research, development/prototype phase and assessment phase. From the results of the research, it is found that students have good response to the resulting work sheet. The worksheet was understood well by students and its helps student in understanding the concept learned.

Full Text Available Objective: The objective of this study was to measure the effect of student-led educational events on geriatric patient and student participant perceptions in a community setting. Methods: Students led three events at a senior community center, focusing on learning and memory, sleep hygiene, and arthritis pain. The participants were geriatric patients who themselves were providers of support to homebound peers (“clients” through an independently organized program. Geriatric participants completed pre- and post-event surveys to measure changes in familiarity with the topics. Student participants also completed pre- and post-event surveys that tracked changes in their comfort in working with the geriatric population. Results: Each event demonstrated at least one positive finding for geriatric patients and/or their clients. Students reported increased comfort in working with and teaching the geriatric population following the first and third events, but not the second. Conclusion: Student-led educational sessions can improve perceived health-related knowledge of geriatric participants while simultaneously exposing students to the geriatric patient population. Overall, both students and geriatric participants benefited from these events. Practice Implications: Incorporation of single, student-led educational events could be mutually beneficial to students and the elderly population in the community and easily incorporated into any healthcare curriculum. Funding:This work was supported by a Butler University Innovation Fund Grant. Treatment of Human Subjects: IRB review/approval required and obtained   Type: Original Research

Student Perceptions of Their Biology Teacher's Interpersonal Teaching Behaviors and Student Achievement

Science.gov (United States)

Madike, Victor N.

Inadequate student-teacher interactions in undergraduate courses have been linked to poor student performance. Researchers have noted that students' perceptions of student-teacher relationships may be an important factor related to student performance. The administration of a Mid-Atlantic community college prioritized increasing undergraduate biology student performance. The purpose of this quantitative study was to examine the relationship between students' biology achievement and their perceptions of interpersonal teaching behaviors and student-teacher interactions in introductory biology courses. Leary's theory on interpersonal communication and the systems communication theory of Watzlawick, Beavin, and Jackson served as the theoretical foundation. The Wubbel's Likert-scale questionnaire on student-teacher interactions was administered to 318 undergraduate biology students. Non-parametric Spearman's rank correlations revealed a significant direct correlation between students' grades and their perceptions of teachers' interpersonal teaching behaviors. The relationship between student achievement and students' perceptions of student-teacher interactions prompted the recommendation for additional study on the importance of student-teacher interactions in undergraduate programs. A recommendation for local practice included faculty development on strategies for improving student-teacher interactions. The study's implications for positive social change include increased understanding for administrators and instructors on the importance of teacher-student interactions at the community college level.

A rainfall risk analysis thanks to an GIS based estimation of urban vulnerability

Renard, Florent; Pierre-Marie, Chapon

2010-05-01

The urban community of Lyon, situated in France in the north of the Rhône valley, comprises 1.2 million inhabitants within 515 km ². With such a concentration of issues, policy makers and local elected officials therefore attach great importance to the management of hydrological risks, particularly due to the inherent characteristics of the territory. If the hazards associated with these risks in the territory of Lyon have been the subject of numerous analyses, studies on the vulnerability of greater Lyon are rare and have common shortcomings that impair their validity. We recall that the risk is seen as the classic relationship between the probability of occurrence of hazards and vulnerability. In this article, this vulnerability will be composed of two parts. The first one is the sensitivity of the stakes facing hydrological hazards as urban runoff, that is to say, their propensity to suffer damage during a flood (Gleize and Reghezza, 2007). The second factor is their relative importance in the functioning of the community. Indeed, not all the stakes could provide the same role and contribution to the Greater Lyon. For example, damage to the urban furniture such as bus shelter seems less harmful to the activities of the urban area than that of transport infrastructure (Renard and Chapon, 2010). This communication proposes to assess the vulnerability of Lyon urban area facing to hydrological hazards. This territory is composed of human, environmental and material stakes. The first part of this work is to identify all these issues so as to completeness. Then, is it required to build a "vulnerability index" (Tixier et al, 2006). Thus, it is necessary to use methods of multicriteria decision aid to evaluate the two components of vulnerability: the sensitivity and the contribution to the functioning of the community. Finally, the results of the overall vulnerability are presented, and then coupled to various hazards related to water such as runoff associated with

The purpose of this study is to reveal the development of knowledge of ordinary students to be like gifted students in the classroom based on Piaget's theory. In exposing it, students are given an open problem of classical analogy. Researchers explore students who conjecture via analogical reasoning in problem solving. Of the 32 students, through the method of think out loud and the interview was completed: 25 students conjecture via analogical reasoning. Of the 25 students, all of them have almost the same character in problem solving/knowledge construction. For that, a student is taken to analyze the thinking process while solving the problem/construction of knowledge based on Piaget's theory. Based on Piaget's theory in the development of the same knowledge, gifted students and ordinary students have similar structures in final equilibrium. They begin processing: assimilation and accommodation of problem, strategies, and relationships.

2017-09-01

Understanding obsessive-compulsive behavior in medical students and law students is necessary for administrators and educators to properly work with students struggling with obsessionality. We aim to compare the differences in obsessive symptoms between medical students, law students and a control population. A total of 100 third-year medical students, 102 third-year law students and 103 control subjects drawn from the general population completed the Leyton Obsessional Inventory (LOI). Subjects were examined on all three sections (symptoms/traits, resistance and interference) of the LOI. Obsessional symptom scores for medical students (14.29 ± 7.33) and law students (13.65 ± 6.61) were significantly greater than for the control group (11.58 ± 7.45). Medical and law students were both more likely to report checking, order, routine and attention to detail as obsessive symptoms. Medical students were more likely than law students to possess the obsessive symptoms of cleanliness and conscientiousness, while law students were more likely than medical students to possess obsessive symptoms related to difficulty in making up their mind and doubting themselves. While medical students and law students are more obsessional than the control population, each group is more likely to report different obsessive symptoms.

Objective. To determine the impact of student or faculty facilitation on student self-assessed attitudes, confidence, and competence in motivational interviewing (MI) skills; actual competence; and evaluation of facilitator performance. Methods. Second-year pharmacy (P2) students were randomly assigned to a student or faculty facilitator for a four-hour, small-group practice of MI skills. MI skills were assessed in a simulated patient encounter with the mMITI (modified Motivational Interviewing Treatment Integrity) tool. Students completed a pre-post, 6-point, Likert-type assessment addressing the research objectives. Differences were assessed using a Mann-Whitney U test. Results. Student (N=44) post-test attitudes, confidence, perceived or actual competence, and evaluations of facilitator performance were not different for faculty- and student-facilitated groups. Conclusion. Using pharmacy students as small-group facilitators did not affect student performance and were viewed as equally favorable. Using pharmacy students as facilitators can lessen faculty workload and provide an outlet for students to develop communication and facilitation skills that will be needed in future practice.

Student assistantships: bridging the gap between student and doctor

Directory of Open Access Journals (Sweden)

Crossley JGM

2015-06-01

Full Text Available James GM Crossley,1,2 Pirashanthie Vivekananda-Schmidt1 1University of Sheffield School of Medicine, Sheffield, 2Chesterfield Royal Hospital NHS Foundation Trust, Chesterfield, UK Abstract: In 2009, the General Medical Council UK (GMC published its updated guidance on medical education for the UK medical schools – Tomorrow's Doctors 2009. The Council recommended that the UK medical schools introduce, for the first time, a clinical placement in which a senior medical student, “assisting a junior doctor and under supervision, undertakes most of the duties of an F1 doctor”. In the UK, an F1 doctor is a postgraduation year 1 (PGY1 doctor. This new kind of placement was called a student assistantship. The recommendation was considered necessary because conventional UK clinical placements rarely provided medical students with opportunities to take responsibility for patients – even under supervision. This is in spite of good evidence that higher levels of learning, and the acquisition of essential clinical and nontechnical skills, depend on students participating in health care delivery and gradually assuming responsibility under supervision. This review discusses the gap between student and doctor, and the impact of the student assistantship policy. Early evaluation indicates substantial variation in the clarity of purpose, setting, length, and scope of existing assistantships. In particular, few models are explicit on the most critical issue: exactly how the student participates in care and how supervision is deployed to optimize learning and patient safety. Surveys indicate that these issues are central to students' perceptions of the assistantship. They know when they have experienced real responsibility and when they have not. This lack of clarity and variation has limited the impact of student assistantships. We also consider other important approaches to bridging the gap between student and doctor. These include supporting the

The Multiverse education group at UC Berkeley's Space Sciences Lab created the NASA-funded "Five Stars Pathway" model in which five "generations" of girls and women engage in science together in an afterschool setting, with each generation representing one stage in the pathway of pursuing a career in science, technology, engineering, or math (STEM). The five stages are: elementary-age students, middle-school-age students, undergraduate-level college students, graduate-level college students and professional scientists. This model was field-tested at two Girls Inc. afterschool locations in the San Francisco Bay Area and distributed to Girls Inc. affiliates and other afterschool program coordinators nationwide. This presentation will explore some of the challenges and success of implementing a multigenerational STEM model as well as distributing the free curriculum for interested scientists and college students to use with afterschool programs.

Educational research emphasizes the advantages of multimethod designs. However, if the design comprises different perspectives, the question of construct validity emerges. We related this question to student and teacher ratings of student-student relations, which are of high interest in research on physical education. In our study, 2,160 students…

From students to researchers: The education of physics graduate students

Science.gov (United States)

Lin, Yuhfen

This dissertation aims to make two research contributions: (1) In physics education research, this work aims to advance our understanding of physics student learning at the graduate level. This work attempts to better understand how physics researchers and teachers are produced, and what factors support or encourage the process of becoming a researcher and a teacher. (2) In cognitive science research in the domain of expert/novice differences, researchers are interested in defining and understanding what expertise is. This work aims to provide some insight into some of the components of expertise that go into becoming a competent expert researcher in the domain of physics. This in turn may contribute to our general understanding of expertise across multiple domains. Physics graduate students learn in their classes as students, teach as teaching assistants, and do research with research group as apprentices. They are expected to transition from students to independent researchers and teachers. The three activities of learning, teaching, and research appear to be very different and demand very different skill-sets. In reality, these activities are interrelated and have subtle effects on each other. Understanding how students transition from students to researchers and teachers is important both to PER and physics in general. In physics, an understanding of how physics students become researchers may help us to keep on training physicists who will further advance our understanding of physics. In PER, an understanding of how graduate students learn to teach will help us to train better physics teachers for the future. In this dissertation, I examine physics graduate students' approaches to teaching, learning, and research through semi-structured interviews. The collected data is interpreted and analyzed through a framework that focuses on students' epistemological beliefs and locus of authority. The data show how students' beliefs about knowledge interact with their

Varroa destructor Mites Can Nimbly Climb from Flowers onto Foraging Honey Bees.

Directory of Open Access Journals (Sweden)

David T Peck

Full Text Available Varroa destructor, the introduced parasite of European honey bees associated with massive colony deaths, spreads readily through populations of honey bee colonies, both managed colonies living crowded together in apiaries and wild colonies living widely dispersed in natural settings. Mites are hypothesized to spread between most managed colonies via phoretically riding forager bees when they engage in robbing colonies or they drift between hives. However, widely spaced wild colonies show Varroa infestation despite limited opportunities for robbing and little or no drifting of bees between colonies. Both wild and managed colonies may also exchange mites via another mechanism that has received remarkably little attention or study: floral transmission. The present study tested the ability of mites to infest foragers at feeders or flowers. We show that Varroa destructor mites are highly capable of phoretically infesting foraging honey bees, detail the mechanisms and maneuvers by which they do so, and describe mite behaviors post-infestation.

The Belgo-Indian Network for Astronomy and Astrophysics (BINA) is a collaboration between Indian and Belgian astronomical institutes with the main aim to optimize the scientific output of the Indo-Belgian telescopes, being the 4.0-m International Liquid Mirror Telescope and the 3.6-m Devasthal Optical Telescope. These new facilities are both located at the Devasthal Observatory near Nainital, India. In this contribution, we introduce projects that are of scientific interest for colleagues of the department "Astronomy and Astrophysics" of the Royal Observatory of Belgium (ROB). It serves as an invitation for Indian astronomers to participate. We highlight how these projects could benefit from observations with the Indo-Belgian telescopes by using instruments from the first-generation (currently offered) and/or the next-generation (development or design phase). We show that, from an ROB point-of-view, the BINA would be the most successful if the 3.6-m DOT would be equipped with an efficient optical high-resolution spectrograph.

Middle-Ear Microsurgery Simulation to Improve New Robotic Procedures

Directory of Open Access Journals (Sweden)

Guillaume Kazmitcheff

2014-01-01

Full Text Available Otological microsurgery is delicate and requires high dexterity in bad ergonomic conditions. To assist surgeons in these indications, a teleoperated system, called RobOtol, is developed. This robot enhances gesture accuracy and handiness and allows exploration of new procedures for middle ear surgery. To plan new procedures that exploit the capacities given by the robot, a surgical simulator is developed. The simulation reproduces with high fidelity the behavior of the anatomical structures and can also be used as a training tool for an easier control of the robot for surgeons. In the paper, we introduce the middle ear surgical simulation and then we perform virtually two challenging procedures with the robot. We show how interactive simulation can assist in analyzing the benefits of robotics in the case of complex manipulations or ergonomics studies and allow the development of innovative surgical procedures. New robot-based microsurgical procedures are investigated. The improvement offered by RobOtol is also evaluated and discussed.

Chalcones were recently found to be potent and specific inhibitors, but unfortunately display a significant cytotoxicity. A cellular screening against ABCG2-mediated mitoxantrone efflux was performed here by flow cytometry on 54 chalcone derivatives from three different series with a wide panel of substituents. The identified leads, with submicromolar IC50 (half maximal inhibitory concentration values, showed that the previously identified 2'-OH-4',6'-dimethoxyphenyl, as A-ring, could be efficiently replaced by a 2'-naphthyl group, or a 3',4'-methylenedioxyphenyl with lower affinity. Such a structural variability indicates polyspecificity of the multidrug transporter for inhibitors. At least two methoxyl groups were necessary on B-ring for optimal inhibition, but substitution at positions 3, 4, and 5 induced cytotoxicity

We report on the fabrication and characterization of Resistive Random Access Memory (RRAM) devices based on nanoparticles in MIM structures. Our approach is based on the use of indium oxide (In2O3) nanoparticles embedded in a dielectric matrix using CMOS-full-compatible fabrication processes in view of back-end-off-line integration for non-volatile memory (NVM) applications. A bipolar switching behavior has been observed using current-voltage measurements (I-V) for all devices. Very high ION/IOFF ratios have been obtained up to 108. Our results provide insights for further integration of In2O3 nanoparticles-based devices for NVM applications. He is currently a Postdoctoral Researcher in the Institute of Nanotechnologies of Lyon (INL), INSA de Lyon, France, in the Electronics Department. His current research include indium oxide nanoparticles for non-volatile memory applications, and the integrations of these devices in CMOS BEOL.

2018-02-01

Student attitudes, defined as the extent to which one holds expertlike beliefs about and approaches to physics, are a major research topic in physics education research. An implicit but rarely tested assumption underlying much of this research is that student attitudes play a significant part in student learning and performance. The current study directly tested this attitude-learning link by measuring the association between incoming attitudes (Colorado Learning Attitudes about Science Survey) and student learning during the semester after statistically controlling for the effects of prior knowledge [early-semester Force Concept Inventory (FCI) or Brief Electricity and Magnetism Assessment (BEMA)]. This study spanned four different courses and included two complementary measures of student knowledge: late-semester concept inventory scores (FCI or BEMA) and exam averages. In three of the four courses, after controlling for prior knowledge, attitudes significantly predicted both late-semester concept inventory scores and exam averages, but in all cases these attitudes explained only a small amount of variance in concept-inventory and exam scores. Results indicate that after accounting for students' incoming knowledge, attitudes may uniquely but modestly relate to how much students learn and how well they perform in the course.

Standardised patients are used in medical education to expose students to clinical contexts and facilitate transition to clinical practice, and this approach is gaining momentum in physiotherapy programs. Expense and availability of trained standardised patients are factors limiting widespread adoption, and accessing clinical visits with real patients can be challenging. This study addressed these issues by engaging senior students as standardised patients for junior students. It evaluated how this approach impacted self-reported constructs of both the junior and senior students. Learning activities for undergraduate physiotherapy students were developed in five courses (Neurology, Cardiorespiratory and three Musculoskeletal courses) so that junior students (Year 2 and 3) could develop skills and confidence in patient interview, physical examination and patient management through their interaction with standardised patients played by senior students (Year 4). Surveys were administered before and after the interactions to record junior students' self-reported confidence, communication, preparedness for clinic, and insight into their abilities; and senior students' confidence and insight into what it is like to be a patient. Satisfaction regarding this learning approach was surveyed in both the junior and senior students. A total of 253 students completed the surveys (mean 92.5% response rate). Across all courses, junior students reported a significant (all P Senior students demonstrated a significant improvement in their confidence in providing feedback and insight into their own learning (P senior students as standardised patients resulted in positive experiences for both junior and senior students across a variety of physiotherapy areas, activities, and stages within a physiotherapy program.

"Nursing Students Assaulted": Considering Student Safety in Community-Focused Experiences.

Science.gov (United States)

Maneval, Rhonda E; Kurz, Jane

2016-01-01

Community nursing experiences for undergraduate students have progressed beyond community-based home visits to a wide array of community-focused experiences in neighborhood-based centers, clinics, shelters, and schools. Our Bachelor of Science in Nursing program chose to use sites situated within neighborhoods close to campus in order to promote student and faculty engagement in the local community. These neighborhood sites provide opportunities for students to deliver nursing services to underserved and vulnerable populations experiencing poverty and health disparities. Some of these neighborhoods are designated as high crime areas that may potentially increase the risk of harm to students and faculty. There is a need to acknowledge the risk to personal safety and to proactively create policies and guidelines to reduce potential harm to students engaged in community-focused experiences. When a group of baccalaureate nursing students was assaulted while walking to a neighborhood clinic, the faculty was challenged as how to respond given the lack of policies and guidelines. Through our experience, we share strategies to promote personal safety for students and recommend transparency by administrators regarding potential safety risks to students engaged in community-focused fieldwork activities.
