Gas Sloshing in Abell 2204: Constraining the Properties of the Magnetized Intracluster Medium
Authors: Chen Huanqing , Jones Christine , Andrade-Santos Felipe , ZuHone John A. , Li Zhiyuan 
Published: March 2017

Abstract
The rich galaxy cluster Abell 2204 exhibits edges in its X-ray surface brightness at ∼65 and

west and east of its center, respectively. The presence of these edges, which were interpreted as sloshing cold fronts, implies that the intracluster medium (ICM) was recently disturbed. We analyze the properties of the ICM using multiple Chandra observations of Abell 2204. We find a density ratio of

and a temperature ratio of

(projected, or 1.87 ± 0.56 deprojected) across the western edge, and correspondingly

and

(projected, or 1.25 ± 0.26 deprojected) across the eastern edge. These values are typical of cold fronts in galaxy clusters. This, together with the spiral pattern observed in the cluster core, supports the sloshing scenario for Abell 2204. No Kelvin–Helmholtz eddies are observed along the cold front surfaces, indicating that they are effectively suppressed by some physical mechanism. We argue that the suppression is likely facilitated by the magnetic fields amplified in the sloshing motion and deduce from the measured gas properties that the magnetic field strength should be greater than 24 ± 6 μG and 32 ± 8 μG along the west and east cold fronts, respectively.

Published: March 2017

Background There is evidence that HIV antiretroviral therapy adverse effects may be sex-dependent, but data examining these sex differences in muscle strength is scarce. Our aim was to compare dynamic and isokinetic parameters of muscle strength between HIV-infected men and women to HIV-uninfected subjects. Methods In this cross-sectional study, muscle strength was evaluated in 44 HIV-infected (20 men, 24 women) and 25 age-, race- and body mass index-matched HIV-uninfected subjects (11 men, 14 women). We assessed knee flexion and extension efforts in isokinetic dynamometer at angular velocities of 60° and 180°/s, and 1 repetition maximum test (1RM) for bench press, leg press and arm curl exercises, respectively. Lean body mass (LBM) was measured using bioelectrical impedance. Results HIV-infected men had significantly less dynamic muscle strength for 1RM total (262.5 versus 357.2 kg), bench press (48.6 versus 60.3 kg), leg press (182.7 versus 261 kg) and arm curl (31.2 versus 36.5 kg) compared to HIV-uninfected men ( P≤0.05); no differences were found among women. Men had lower values for peak torque in extension and flexion movements at 60°/s and 180°/s, while HIV-infected women presented higher peak torque in extension movement at 60°/s compared to controls. No differences were found in LBM. Moreover, isokinetic evaluation demonstrated that HIV-infected subjects showed greater acceleration and deceleration time in some variables, compared to controls, related to difficulty in activating motor units. Conclusions HIV infection is associated with impaired dynamic and isokinetic strength in men compared to HIV-uninfected controls, but not in women.
La « génération Y » entrera dans la carrière. Étude intergénérationnelle des schémas de carrière des ingénieurs français
Authors: Pralong Jean , Philippe Xavier , Peretti-Ndiaye Marie 
Published: March 2017

La question intergénérationnelle est croissante dans les préoccupations gestionnaires. Pourtant, la réalité des différences intergénérationnelles demeure spéculative. L’objectif de cet article est de théoriser et d’analyser empiriquement les différences de rapport à la carrière des ingénieurs français de générations différentes. La notion de schéma de carrière est mobilisée pour examiner les influences conjuguées de la génération et des organisations sur les individus. Les résultats sont recueillis auprès d’un échantillon de 613 ingénieurs représentant les trois générations en âge de travailler. Les schémas de carrière des ingénieurs sont structurés par quatre facteurs indépendants ; la variable génération n’a pas d’influence sur ces quatre facteurs.
La philosophie méthodique comme soubassement des sciences, y compris de gestion : l’exemple de la démarche « hypothèse, déductions, test »
Authors: Dromby Frédéric 
Published: March 2017

La manière ‘hypothético-déductive’ de fabriquer de la connaissance est aujourd’hui majoritaire en sciences. Souvent présentée comme inspirée des mathématiques, elle a en fait son mode de fonctionnement propre. Originellement posée comme substitut à une démarche purement déductive (« Faute de mieux » est l’expression qui introduisit sa vraisemblable première occurrence voici 24 siècles) elle a progressivement raffiné & augmenté ses outils, ainsi que précisé son rapport à l’expérience. Compliquée cependant, elle peut être obscure aux apprentis-chercheurs. Une analyse philosophique & historique aide à mieux la faire comprendre. Deux périodes-clés sont distinguées, avec pour chacune d’elles, une série de travaux pionniers.

Published: March 2017

Abstract
Woundfin Plagopterus argentissimus are a small, endangered cyprinid found solely in the Virgin River across Utah, Arizona, and Nevada. As of now, only three facilities culture Woundfin for conservation propagation purposes, but there is growing concern that current extensive culture protocols are not meeting the conservation recovery goals outlined in the Virgin River Resource Management and Recovery Program. The development of alternative rearing methodology, like effective intensive culture conditions, could help increase production to more effectively meet the conservation propagation needs for this species. Our goal was to assess the effect of different sex ratios and fish densities on reproductive success at indoor facilities. We measured fertilization success at three different sex ratios (1:1, 1:3, 1:5; female:male) and three different fish densities (0.05, 0.21, and 0.47 fish/L) in a laboratory setting. Sex ratio did not significantly affect fertilization success (P = 0.73). Fertilization was completely inhibited at a density of 0.05 fish/L, but there was no difference in fertilization success between the two other density treatments (P = 0.92). Our findings suggest that a density greater than 0.05 fish/L and a sex ratio of 1:1, 1:3, or 1:5 will likely enhance fertilization success. The results and conclusions of this paper provide valuable rearing information for the Virgin River Resource Management and Recovery Program and hatchery managers attempting to increase production of Woundfin in an intensive culture setting.
Mimesis et filiation artistique : la question du style de Lysippe et de ses disciples dans l’épigramme 62 A.‑B. de Posidippe et chez Pline l’Ancien (NH 34, 66)
Authors: Prioux Évelyne , Santin Eleonora 
Published: March 2017

Par cet article nous souhaitons examiner, à travers le cas particulier de Lysippe, le processus d’élaboration de la notion de filiation artistique dans la critique d’art ancienne. Il s’agira notamment de voir comment les théoriciens du début de l’époque hellénistique ont envisagé les rapports d’imitation entre Lysippe et ses disciples, ainsi que les phénomènes de continuité ou de discontinuité stylistique entre le maître et ses successeurs. Le point de départ de cette étude est la première épigramme du cycle des andriantopoiika de Posidippe, dont nous souhaitons mettre en évidence les liens avec des théories probablement exposées dans les traités contemporains de Douris de Samos et de Xénocrate d’Athènes. Cette épigramme mentionne trois artistes « anciens » (peut-être trois générations d’artistes : maître, disciple et Enkelschüler) dont les œuvres sont caractérisées comme « rigides » et opposées à celles des nouveaux artistes qui suivent les préceptes de Lysippe, un artiste qui passait, selon certaines anecdotes, pour n’avoir été formé par aucun maître, mais par la nature elle-même. Les autres épigrammes que Posidippe consacre aux bronziers montrent que les principes de Lysippe ont pu inspirer des œuvres aussi différentes que le portrait très précis du vieux poète Philitas par le bronzier Hécataios ou la représentation auguste et colossale du dieu Hélios par Charès de Lindos. Un passage plinien lui aussi inspiré de ces premiers traités d’histoire de l’art, la description des qualités stylistiques de l’œuvre d’Euthycrate, disciple de Lysippe, fait état d’une conception de la transmission de l’enseignement artistique, des qualités stylistiques et du savoir technique entre le maître et son disciple qui rejoint les présupposés théoriques de Posidippe. Le vocabulaire stylistique employé dans ce passage de Pline nous permet de deviner la complexité de l’appareil théorique élaboré, au début de l’époque hellénistique, par Xénocrate et Douris.
La qualité : itinéraire d’un concept entre usage et théorie dans un dispositif de formation ouverte en langue étrangère
Authors: Ismail Nancy 
Published: March 2017

Le concept de qualité ne concerne plus seulement les produits mais aussi les services ; il n’est plus réservé au secteur de l’industrie mais il envahit également le domaine de la formation et notamment les centres de langues dans le supérieur. Cela se manifeste, entre autres, par l’obtention de labels, à l’image du département de français langue étrangère de l’université de Lorraine (DéFLE-Lorraine) qui a obtenu le « Label Qualité FLE ». Son dispositif de formation ouverte en présentiel s’articule autour de plusieurs modalités d’accompagnement pour mieux se centrer sur les apprenants, leurs dispositions (représentations et motivations) et prendre en compte la diversité de leurs exigences (besoins et attentes). Cette prise en compte repose sur un processus d’évaluation multidimensionnel, externe et interne, qui contribue d’une part à mesurer le degré de compétence des apprenants, et d’autre part à contrôler la qualité de notre offre de formation et de nos services.
Spécialiser la compétence B2 en anglais dans le cadre d’une démarche qualité : Une proposition pour le secteur Lansad
Authors: Millot Philippe 
Published: March 2017

Cet article présente un exemple d’adaptation du niveau B2 du Cadre européen commun de référence pour les langues sur la base d’une démarche qualité dans la faculté de philosophie d’une université française. La démarche consiste à attester une compétence à la fois pertinente et accessible pour des étudiants qui sont spécialistes d’une discipline et pour qui l’anglais remplit la double fonction d’accès à la culture spécialisée et de langue de communication internationale. L’attestation de la compétence suppose la mise en place de ce que nous considérons comme trois facettes essentielles de la démarche qualité en anglais de spécialité : la mise en place de cours orientés vers la compétence spécialisée, la conception d’un certificat et la création d’un corpus d’anglais de spécialité représentatif de la compétence visée.
Insecticide resistance in field populations of Leucinodes orbonalis (Lepidoptera: Crambidae) in India

Published: March 2017

AbstractThe status of insecticide resistance in field populations of eggplant fruit and shoot borer, Leucinodes orbonalis (Guenée) (Lepidoptera: Crambidae) from the major vegetable growing regions of India was determined during the cropping seasons of 2009–2010 and 2010–2011. Six commonly used insecticides: carbaryl, chlorpyriphos, deltamethrin, endosulfan, fenvalerate, and profenofos were tested against L. orbonalis larvae. The resistance ratios (RR) at the lethal dosage (LD)50 levels were estimated as RR=LD50 field strain/LD50 susceptible strain. The L. orbonalis populations exhibited widespread resistance to tested insecticides. The highest average RR in the two-year study was observed in the assays of populations with deltamethrin (21.50–82.42-fold) followed by assays conducted with endosulfan (24.47–68.26-fold), chlorpyriphos (22.17–63.14-fold), carbaryl (39.18–49.09-fold), and fenvalerate (14.00–44.66-fold); and the lowest average RRs were observed in the assays with profenofos (16.65–39.43-fold). The high levels of LD50 values can be attributed to the long-term indiscriminate use of these insecticides in eggplant (Solanum melongena Linnaeus; Solanaceae) growing regions.
Relation of anomalous F region radar echoes in the high-latitude ionosphere to auroral precipitation
Authors: Dahlgren Hanna , Schlatter Nicola M. , Ivchenko Nickolay , Roth Lorenz , Karlsson Alexander 
Published: March 2017

Abstract. Non-thermal echoes in incoherent scatter radar observations are occasionally seen in the high-latitude ionosphere. Such anomalous echoes are a manifestation of plasma instabilities on spatial scales matching the radar wavelength. Here we investigate the occurrence of a class of spatially localized anomalous echoes with an enhanced zero Doppler frequency feature and their relation to auroral particle precipitation. The ionization profile of the E region is used to parametrize the precipitation, with nmE and hmE being the E region peak electron density and the altitude of the peak, respectively. We find the occurrence rate of the echoes to generally increase with nmE and decrease with hmE, thereby indicating a correlation between the echoes and high-energy flux precipitation of particles with a high characteristic energy. The highest occurrence rate of > 20 % is found for hmE  =  109 km and nmE  =  1011. 9 m−3, averaged over the radar observation volume.
Design and Modelling of a Cable-Driven Parallel-Series Hybrid Variable Stiffness Joint Mechanism for Robotics
Authors: Yigit Cihat Bora , Boyraz Pinar 
Published: March 2017

Abstract. The robotics, particularly the humanoid research field, needs new mechanisms to meet the criteria enforced by compliance, workspace requirements, motion profile characteristics and variable stiffness using lightweight but robust designs. The mechanism proposed herein is a solution to this problem by a parallel-series hybrid mechanism. The parallel term comes from two cable-driven plates supported by a compression spring in between. Furthermore, there is a two-part concentric shaft, passing through both plates connected by a universal joint. Because of the kinematic constraints of the universal joint, the mechanism can be considered as a serial chain. The mechanism has 4 degrees of freedom (DOF) which are pitch, roll, yaw motions and translational movement in z axis for stiffness adjustment. The kinematic model is obtained to define the workspace. The helical spring is analysed by using Castigliano's Theorem and the behaviour of bending and compression characteristics are presented which are validated by using finite element analysis (FEA). Hence, the dynamic model of the mechanism is derived depending on the spring reaction forces and moments. The motion experiments are performed to validate both kinematic and dynamic models. As a result, the proposed mechanism has a potential use in robotics especially in humanoid robot joints, considering the requirements of this robotic field.
Reduction in resource utilization and increase in patient satisfaction two years after implementation of Perioperative Surgical Home
Authors: Mangar Devanand , Dalvi Prachiti H. , Bernasek Thomas , Camporesi Enrico 
Published: March 2017

Introduction: Perioperative Surgical Home (PSH) provides coordinated, team-based care that is patient-centered, designed to guide patients efficiently through the surgical experience. We applied several changes to our anesthesia practice during 2014 and evaluated outcomes for all orthopedic major joint replacement surgeries completed in 2015. Since this was a quality improvement/utilization study, we were granted approval from our institutional review board to retrospectively review these data.Methods: We conducted a utilization review of all 1,356 patients who received total knee, hip, or shoulder joint replacement from 4 major surgical providers in 2015. Preoperative evaluation was limited and focused to each patient’s unique medical conditions. Additionally, we reduced intraoperative fluid use, reduced continuous femoro-sciatic nerve or brachial plexus blocks by increasing the administration of single-shot regional blocks, limited transfusion, and minimized urinary catheter use. We improved pain consult response time and provided timely discharges.Results: We noted 9% reduction in preoperative imaging per case, 22% decrease in average number of tests per case, 87% fewer average units of red blood cell used per case, and a 0.4 day reduction in average length of stay (LOS). Patient satisfaction data showed constant improvement in pain management, and doctor communication.Conclusions: Numerous small modifications to patient care collectively contributed to these progressive observed changes in patient outcomes from quarter to quarter.

Glossostyles perspicua gen. et sp. nov. and other fungivorous Cecidomyiidae (Diptera) new to the Czech and Slovak Republics
Authors: Sikora Tomáš , Jaschhof Mathias , Ševčík Jan 
Published: March 2017

Fungivorous gall midges of the subfamilies Lestremiinae, Micromyinae, Winnertziinae and Porricondylinae were largely neglected in previous inventories of the Diptera faunas of the Czech and Slovak Republics. A taxonomic-faunistic study focusing on these subfamilies identified a total of 80 species, of which 49 are new records for the Czech Republic and 33 are new records for Slovakia. Species that have never before been found in central Europe are Aprionus dalarnensis Mamaev, 1998, A. oligodactylus Jaschhof, 2009, A. pigmentalis Mamaev, 1998, Asynapta inflata Spungis, 1988, Camptomyia gigantea Spungis, 1989, Cassidoides fulviventris (Mamaev, 1964), Claspettomyia hamata (Felt, 1907), Dendrepidosis longipennis (Spungis, 1981), Dicerura dispersa Jaschhof, 2013, Divellepidosis lutescens (Spungis, 1981), D. pallescens (Panelius, 1965), D. vulgata Jaschhof, 2013, Ekmanomyia svecica Jaschhof, 2013, Holoneurus ciliatus Kieffer, 1896, Monepidosis pectinatoides Jaschhof, 2013, Neocolpodia gukasiani (Mamaev, 1990), Neurolyga acuminata Jaschhof, 2009, Neurolyga interrupta Jaschhof, 2009, Parepidosis planistylata Jaschhof, 2013, Peromyia bidentata Berest, 1988, Porricondyla errabunda Mamaev, 2001, P. microgona Jaschhof, 2013, P. tetraschistica Mamaev, 1988, Schistoneurus irregularis Mamaev, 1964, Spungisomyia fenestrata Jaschhof, 2013, S. media (Spungis, 1981), Tetraneuromyia lamellata Spungis, 1987, T. lenticularis (Spungis, 1987), and Winnertzia parvispina Jaschhof, 2013. A new genus including a single new species of Porricondylini is described and named Glossostyles perspicua Jaschhof & Sikora gen. et sp. nov. on the basis of specimens collected in the Czech Republic and Sweden. Adult morphology suggests that Glossostyles gen. nov. is a close relative of Claspettomyia Grover, 1964.
