Causes et conséquences géographiques de la métropolisation et de l'exurbanisation (Geographical causes and effects of metropolization and exurbanization)
Authors: Dezert Bernard
Published: June 2015

Résumé. - Les causes de la métropolisation sont à chercher dans l'exode rural et les mutations techniques qui favorisent les emplois tertiaires, particulièrement dans le tertiaire supérieur. Une nouvelle logistique d'entreprises favorise l'exurbanisation d'un grand nombre d'activités de production, de recherche et de services. L'exurbanisation est la résultante d'une hyperconcentration des bureaux et du centre directionnel. Un nouveau système dual de relations étroites centre- périphérie s'est organisé, impliquant une nouvelle logique de l'espace : les nouvelles implantations sont surtout périphériques. Dans cette nouvelle conception de l'espace des entreprises, l'accessibilité aux transports joue un rôle essentiel et justifie une exurbanisation décentralisée.
Contribution à la méthode d'évaluation des risques dans les villes des PVD (Ibagué, Colombie) (Enquiries about risk knowledge and consciousness in Colombia)
Authors: Laforge C. , Thouret Jean-Claude
Published: June 2015

Résumé. - Dans le cadre des opérations de planification urbaine préventive décrétées en Colombie en 1989, une évaluation des aléas hydro-volcaniques par micro-zonage et des risques par enquêtes de vulnérabilité et de perception a été entreprise dans les quartiers les plus menacés de la ville d'Ibagué (Tolima), dans la vallée du Rio Combeima. L'efficacité de l'évaluation des risques et de la prévention dépend de la qualité du micro-zonage de vulnérabilité et du déchiffrage, chez les citadins, des relations unissant les connaissances acquises et la perception des risques avec le comportement prévisible en cas d'alerte.

La tempête, du moment de Nature au spectacle de Société (The storm, sight and risk for the society)
Authors: Bousquet Bernard , Miossec Alain
Published: June 2015

Résumé. - La tempête change selon le type de littoral sur lequel elle sévit. Phénomène de morphogenèse rapide pour le littoral de Nature, elle est un moment qui transforme jusqu'à son effraction le rivage. Pour le littoral d'oekoumène, elle est une menace pour les biens riverains. La défense côtière fondée sur des ouvrages de protection y est menée dans le but de conserver au trait de côte son emplacement. Pour le littoral d'institution, la tempête détruit une limite à valeur cadastrale que l'administration et les services techniques ont la charge d'identifier et de garantir parfois dans un équilibre dangereux. La gestion littorale du trait de côte entraîne l'implantation d'équipements qui peuvent introduire un risque lorsque la rigidité du trait de côte est privilégiée aux dépens de sa mobilité naturelle. La diversité que revêt le phénomène vient de ce que la tempête fut d'abord spectacle pour les riverains avant d'être interprétée comme un moment, c'est-à-dire mouvement de la Nature.
Aristathlus imperatorius Bergroth, a newly recognized synonym of Reduvius iopterus Perty, with the new combination Aristathlus iopterus (Perty, 1834) (Hemiptera: Reduviidae: Harpactorinae) ​
Authors: Gil-Santana Hélcio , Forero Dimitri
Published: June 2015

Reduvius iopterus Perty 1834 was first described from the Rio Negro, Brazil. It was then included in Zelus Fabricius 1803 as Z. iopterus (Perty 1834) without critical examination of this action (Stål 1872).The Neotropical genus Aristathlus Bergroth 1913 was described to include two species from the Amazon basin: A. imperatorius Bergroth 1913 and A. regalis Bergroth 1913.

Based on the original description and illustration of Reduvius iopterus, Aristathlus imperatorius is considered to be its junior synonym, with the resulting new combination: Aristathlus iopterus (Perty 1834).
Incidence and Management of Infusion Reactions to Infliximab in a Prospective Real-world Community Registry
Authors: Choquette Denis , Faraawi Rafat , Chow Andrew , Rodrigues Jude , Bensen William J. , Nantel Francois
Published: June 2015

Objective.

Infliximab (IFX) is a therapeutic monoclonal antibody targeting tumor necrosis factor-α indicated in the treatment of chronic inflammatory diseases. IFX is administered by intravenous infusion and may be associated with different types of infusion reactions.

Methods.

RemiTRAC Infusion (NCT00723905) is a Canadian observational registry in which patients receiving IFX are followed prospectively to document premedication use, adverse events, infusion reactions, and the management of infusion reactions. The primary endpoint was to assess factors associated with infusion reactions.

Results.

There were 1632 patients enrolled and 24,852 infusions recorded. Most patients (63.1%) were treated for rheumatologic conditions such as rheumatoid arthritis, ankylosing spondylitis, or psoriatic arthritis. Of the 1632 patients, 201 (12.3%) reported at least 1 infusion reaction. Three hundred twenty-two infusions were associated with an infusion reaction (1.3%), and most were mild to moderate in severity (95%). The most common infusion reactions were pruritus (19.9%), flushing (9.9%), or dyspnea (6.2%). Multivariate analysis showed that antihistamines premedication, number of previous infusion reactions, and female sex were significantly associated with an increased incidence of infusion reactions (p < 0.0011). The use of any concomitant immunosuppressant or corticosteroids did not influence the incidence of infusion reactions. Antihistamine premedication was associated with an increased incidence of infusion reactions (OR 1.58, p = 0.0007).

Conclusion.

This registry shows that in community-based infusion clinics, infusion reactions to IFX are uncommon and mild to moderate in nature. Antihistamines, intravenous steroids, and acetaminophen are widely used as preventative premedication, although this study showed an absence of benefit with their use.
Update on Outcome Measure Development for Large Vessel Vasculitis: Report from OMERACT 12

Published: June 2015

Objective.

The rarity of large vessel vasculitis (LVV) is a major factor limiting randomized controlled trials in LVV, resulting in treatment choices in these diseases that are guided mainly by observational studies and expert opinion. Further complicating trials in LVV is the absence of validated and meaningful outcome measures. The Outcome Measures in Rheumatology (OMERACT) vasculitis working group initiated the Large Vessel Vasculitis task force in 2009 to develop data-driven, validated outcome tools for clinical investigation in LVV. This report summarizes the progress that has been made on a disease activity assessment tool and patient-reported outcomes in LVV as well as the group’s research agenda.

Methods.

The OMERACT LVV task force brought an international group of investigators and patient research partners together to work collaboratively on developing outcome tools. The group initially focused on disease activity assessment tools in LVV. Following a systematic literature review, an international Delphi exercise was conducted to obtain expert opinion on principles and domains for disease assessment. The OMERACT vasculitis working group’s LVV task force is also conducting qualitative research with patients, including interviews, focus groups, and engaging patients as research partners, all to ensure that the approach to disease assessment includes measures of patients’ perspectives and that patients have input into the research agenda and process.

Results.

The preliminary results of both the Delphi exercise and the qualitative interviews were discussed at the OMERACT 12 (2014) meeting and the completion of the analyses will produce an initial set of domains and instruments to form the basis of next steps in the research agenda.

Conclusion.

The research agenda continues to evolve, with the ultimate goal of developing an OMERACT-endorsed core set of outcome measures for use in clinical trials of LVV.
Development and Preliminary Validation of a Digital Overlay-based Learning Module for Semiquantitative Evaluation of Magnetic Resonance Imaging Lesions in Osteoarthritis of the Hip
Authors: Maksymowych Walter P. , Pitts Meaghan , Budak Matthew J. , Gracey David , Lambert Robert G. , McDougall David , Pianta Marcus , Rennie Winston J. , Wichuk Stephanie , Winn Naomi , Jaremko Jacob L.
Published: June 2015

Objective.

To develop and validate a knowledge transfer (KT) module aimed at enhancing feasibility and reliability of semiquantitative assessment of bone marrow lesions (BML) and synovitis-effusion using the Hip Inflammation Magnetic Resonance Imaging Scoring System (HIMRISS).

Methods.

Three radiologists naive to the HIMRISS method reviewed the manuscript describing the method and then scored MRI scans from 16 patients with hip OA obtained at baseline and 8 weeks after intraarticular injection of corticosteroid. Readers then reviewed a KT module comprising an instructional presentation and 8 reference DICOM (digital imaging and communications in medicine) cases scored by 3 readers with expertise in the HIMRISS method, and then used electronic overlay software to score scans from 23 patients with OA. The same format was followed with a second group of 3 readers naive to HIMRISS using a KT module revised to incorporate the overlay with a Web-based DICOM viewer to enhance feasibility. Interobserver reliability was assessed with the intraclass correlation coefficient (ICC).

Results.

In both exercises, reliability for baseline scores was excellent for femoral BML, very good for acetabular BML, and good for synovitis-effusion (overall ICC = 0.91, 0.89, 0.62, respectively) even without prior calibration using the KT module. However, reliability for detecting change was substantially worse than for expert readers, especially for acetabular BML and synovitis-effusion (overall ICC = 0.59 vs 0.19, and 0.42 vs 0.25, respectively). Reliability improved for detection of change in these lesions, especially after reader calibration with the revised KT module.

Conclusion.

Development and validation of a systematic method for KT may enhance external validation of certain imaging instruments.
Immunosuppressive Therapies for the Maintenance Treatment of Proliferative Lupus Nephritis: A Systematic Review and Network Metaanalysis
Authors: Tian Simon Yu , Feldman Brian M. , Beyene Joseph , Brown Patrick E. , Uleryk Elizabeth M. , Silverman Earl D.
Published: June 2015

Objective.

To determine the most effective immunosuppressive therapy for the longterm management of proliferative lupus nephritis (PLN) based on the outcome of renal failure.

Methods.

A systematic review of randomized controlled trials (RCT) was conducted. MEDLINE and EMBASE were searched. RCT designed to examine the maintenance treatment effectiveness of immunosuppressive agents for PLN were included. A Bayesian network metaanalysis of 2-arm and 3-arm trials was used. A skeptical prior assumption was used in sensitivity analysis. Four immunosuppressive agents were evaluated: cyclophosphamide (CYC), azathioprine (AZA), mycophenolate mofetil (MMF), and prednisone alone. The outcome of interest was renal failure during the study period, defined by serum creatinine (sCr) > 256µmol/l, doubling of sCr from baseline, and/or endstage renal disease.

Results.

The OR (95% credible interval) of developing renal failure at 2–3 years was 0.72 (0.11, 4.49) for AZA versus CYC, 0.32 (0.04, 2.25) for MMF versus CYC, 2.40 (0.22, 36.94) for prednisone alone versus CYC, and 0.45 (0.11, 1.48) for MMF versus AZA. The probability (95% credible interval) of developing renal failure at 2 years as expected for each agent was 6% (0.7%, 24%) for MMF, 12% (2%, 37%) for AZA, 16% (5%, 33%) for CYC, and 31% (5%, 81%) for prednisone alone. After applying a skeptical prior in the Bayesian analysis, there was no evidence of benefit for 1 therapy over another.

Conclusion.

Although the data suggest that MMF may be superior to other treatments for the maintenance treatment of PLN, the evidence is not conclusive.
Présence et manifestations du religieux dans la télévision des années cinquante
Authors: Cohen Évelyne
Published: June 2015

Dans les années cinquante, les premiers programmes de la télévision française accordent une attention particulière aux émissions à caractère religieux Leur présence tient beaucoup à l’action conjointe du père dominicain Pichard et de Jean d’Arcy, membre du cabinet ministériel du secrétaire d’État à l’information, proche des courants de la Résistance d’inspiration chrétienne. Le premier réussit, non sans mal, à imposer, en 1948, la représentation à la télévision de la messe. Son initiative débouche en octobre 1949 sur une émission toujours programmée en 2015 : Le Jour du Seigneur.

Membre de la Société des missions africaines de Lyon, le père Jacques Bertho (1902-1990) est affecté, en septembre 1929, au Dahomey (Bénin). Il y déploie une activité remarquable de linguiste, archéologue, historien, anthropologue et produit un ensemble sans équivalent de photographies. Elles permettent un usage comparatif des divers bâtis et constituent sorte de conservatoire des architectures de l’Ouest africain durant la période des années 1940-1950.
Des hommes noirs sur l’écran blanc
Authors: Rocher Philippe
Published: June 2015

La contribution analyse la représentation des missions jésuites dans quelques films de fiction, particulièrement Le Festin des morts (1965), Robe noire (1991), Parole et utopie (2000), Amen (2001) et Le Tombeau (2000). Cette mise en images contribue à construire une représentation des jésuites et de leurs missions qui exprime, non sans stéréotypes, la tension permanente entre les raisons des institutions, Église et État, et l’esprit du christianisme.
Les racines du ciel
Authors: Roger Philippe
Published: June 2015

Le religieux ne se limite pas au confessionnel, ni aux films recensés comme tels. L’œuvre du Français Jean Grémillon, des années 1920 aux années 1940, peut se lire comme celle d’un cinéaste qui cherche à inventer une écriture cinématographique capable de suggérer le sacré et d’introduire une dimension mystique dans les films de fiction comme dans les films documentaires.
Le procès de Pasolini pour La Ricotta , un jugement eschatologique ?
Authors: Deloche Pascale
Published: June 2015

Un court-métrage de commande pour un film à sketches donne lieu en 1963 à un procès médiatisé dans lequel Pasolini est accusé de « dénigrement de la religion d’État ». Le procès se tient au moment du concile Vatican II et en pleine période électorale italienne. Il témoigne de tensions politiques, théologiques et esthétiques constitutives du fait religieux lui-même. Et il révèle le déplacement du religieux dans un monde où il devient difficile de l’identifier.
Quelques notes terriblement « vieux jeu »
Authors: Grozdanovitch Denis
Published: June 2015

Cet article rassemble quelques notes disparates tendant à démontrer la présence indéfectible – jusqu’à aujourd’hui du moins – de l’élément ludique ou agonal dans toutes les activités humaines ou animales. Élément qui est malheureusement en passe d’être éradiqué par la montée en puissance d’une idéologie économique et utilitariste (d’obédience anglo-saxonne) qui tend à considérer le règne du vivant comme une sorte de gigantesque machine à exister sur un plan uniquement biologique. Idéologie qui pourrait aboutir à ce résultat : nous transformer tous – hommes ou animaux – en un peuple de robots décervelés seulement soucieux de préserver le bon fonctionnement de leur propre mécanisme et dans les yeux desquels ne scintillerait plus la moindre étincelle de fantaisie ni de plaisir.
Jeu et sociabilité dans le monde animal
Authors: Kropotkine Pierre
Published: June 2015

Cet extrait de l’ouvrage classique du naturaliste anarchiste, L’Entraide. Un facteur de l’évolution , 1902, ne vient pas seulement nous rappeler, contre le darwinisme social d’hier et d’aujourd’hui, combien les espèces qui coopèrent le plus efficacement ont tendance à être les plus compétitives à long terme. Il souligne aussi qu’une majeure partie des formes de coopération animale relève de divers jeux sociaux qui n’ont rien à voir avec la survie ou la reproduction mais constituent une forme de plaisir en eux-mêmes et pour eux-mêmes.
Petit pas de côté
Authors: Hamayon Roberte H.
Published: June 2015

Les principaux auteurs abordent le jeu essentiellement à partir de sa dimension agonistique, dans son rôle de compétition distinguant vainqueurs et vaincus. Ils voient le jeu en game et négligent le play au sens de « représentation » (étymologiquement « saut, danse ») alors que l’anglais utilise le verbe play dans les deux cas. Seul parmi les auteurs classiques, Roger Caillois semble échapper à ce « syndrome de l’ agôn  ». Il fait une place au play mais le dévalorise et le montre reculant au fil de l’histoire face au couple dominateur que la compétition forme avec le hasard. Ce recul reflète l’influence des pouvoirs centralisateurs. La ritualisation du sport illustre la persistance de la dimension représentationnelle. La connotation de virilité liée à la compétition éclaire l’usage de la terminologie du virtuel en rapport avec le jeu.
Un jeu qui réconcilie les règles et la fiction : le jeu de rôles grandeur nature
Authors: Kapp Sébastien
Published: June 2015

Le jeu est, dans la littérature canonique (Huizinga et Caillois), envisagé sous l’angle de son rapport à la culture. Ce rapport est souvent décrit comme un paradoxe. Le jeu s’organiserait autour de deux pôles opposés, voire incompatibles : les règles (ordre et discipline) et la fiction (liberté créative et fantaisie), autrement formulés en game et play . Fondée sur une enquête ethnographique de plusieurs années, cette contribution prend le cas d’un jeu mal connu : le jeu de rôles grandeur nature (GN). Sorte de voyage immersif et ludique dans des univers fictionnels, le GN propose d’incarner des personnages costumés et autonomes, soumis à des règles de simulation très précises, mais non moins libres d’aller et venir à leur guise et de faire leurs propres choix. Réconciliant game et play , règles et fiction, le GN constitue une forme originale de création culturelle non seulement collective mais surtout collaborative.
Don, échanges, correspondances avec l’au-delà : les liens entre les vivants et les morts dans le Lotto italien
Authors: D’Agati Marina
Published: June 2015

De quoi parle-t-on en disant : le pari ou le « parier » ? D'une attitude ? D'un jeu ? De quoi d'autre ? Et est-il permis de parler de don en ce qui concerne le parier ? Cet article examine, à la lumière de la théorie du don, la capacité du pari de favoriser les échanges avec les entités invisibles, notamment d’établir un rapport et une communication entre les vivants et les morts. À partir de l’exemple du Lotto italien, considéré comme modalité de pari organisée, il montre comment certains de ses aspects sont modelés par la « triple obligation » maussienne. Cet article identifie également trois formes de don les plus fréquemment évoquées chez les joueurs du Lotto italien : le rêve , l' apparition , les objets/événements/dates . Il invite ainsi à mettre au jour une notion de sujet-joueur comme acteur rationnel, agissant exprès et d'une façon sensée.
Lettres sur l’éducation esthétique de l’homme (1795-1796)
Authors: von Schiller Friedrich
Published: June 2015

Dès 1795, dans ces fameuses Lettres sur l’éducation esthétique, le poète, dramaturge et philosophe allemand suggérait que c’est du jeu que provient la conscience en soi, et donc la liberté et la moralité. Bref, que « l’homme joue seulement lorsqu’il est, dans le sens complet du mot, un homme, et il est entièrement Homme quand il joue ».
L’agir du jeu
Authors: Lageira Jacinto
Published: June 2015

Sachant que les jeux sont une imitation de l'action des humains, cela sous forme de métaphores, de fictions et de faire-semblant, on insistera sur la dimension de l'« action libre » (Johan Huizinga) et sur les manières dont les jeux peuvent valoir comme des modèles pratico-moraux et pratico-sensibles des actions concrètes, sans se confondre avec ces dernières. Par ailleurs, l'imitation ( mimèsis ) doit être également saisie dans son articulation à la participation ( méthexis ), donc à des formes et à des valeurs de l'agir, lesquelles peuvent conduire à une poétique de l'action.
Éléments pour une ludosophie
Authors: Domeracki Stéphane
Published: June 2015

À partir d'un rapide rappel des rares doctrines philosophiques ayant consenti à thématiser le jeu au sein de leur anthropologie ou ontologie, l'auteur s'efforce tout d'abord de montrer pourquoi il a pu n’être que méprisé pendant des siècles de pensée rationaliste : au mieux, le jeu était instrumentalisé, subordonné. Ce sera donc tardivement que des pensées des ressources ludosophiques pourront être dégagées, consacrant l'innocence du jeu et du sport. N'y a-t-il pas, en effet, sagesse à mettre à profit notre énergie pour des activités largement atéliques, où enfin nous apprenons à jouir de la règle ? L'euphémisation de la violence dont nous sommes porteurs par les activités ludiques est-elle un horizon pertinent ? Nous proposerons ici seulement les linéaments d'une réflexion qui devrait porter sur les légitimes prétentions du jeu, rare oasis d'innocence dans un monde où règne l'instrumentalisation et l'usure.
Mauss et les princes de Serendip
Authors: Parlebas Pierre
Published: June 2015

En étudiant les pratiques des sociétés anciennes, Marcel Mauss a mis en évidence que la triple obligation de donner, recevoir et rendre est au cœur du fonctionnement social. Cette contrainte acceptée se manifeste notamment lors du potlatch , cette cérémonie au cours de laquelle les protagonistes s'offrent des présents fastueux et se battent à coup de cadeaux provocateurs. Dans ce texte retentissant de 1924, Marcel Mauss affirme que le jeu est une forme de potlatch . Dix ans plus tard, dans un nouvel article novateur et magistral, le même auteur montre que les techniques du corps sont profondément sous l'emprise des représentations sociales. Comment comprendre alors que, dans ce dernier texte, le rôle du don/contre-don soit passé sous silence et que les techniques du corps ignorent, dans leur accomplissement praxique, l'échange et le partage avec autrui ? Le phénomène de sérendipité – découverte d'un phénomène inédit, puis son exploitation – n'a pas été mené à son terme. Pourtant, l'univers du sport et des jeux traditionnels se prête à merveille à la manifestation de la triple obligation maussienne. Le cas le plus notoire est celui des jeux paradoxaux dont l'ambivalence illustre de façon spectaculaire les processus du don/contre-don.
Présentation de « Réduction des divers éléments de la magie à la notion de pouvoir et de force » de Marcel Mauss
Authors: Bert Jean-François
Published: June 2015

Ce texte inédit est la transcription de 61 pages manuscrites conservées dans le fonds Henri Hubert du musée d’archéologie nationale de Saint-Germain-en-Laye. Il s’agit de la première version entièrement rédigée par Marcel Mauss de ce qui deviendra, en 1904, l’ Esquisse d’une théorie générale de la magie . Mauss cherche alors à se différencier nettement des manières classiques de définir la magie en insistant longuement sur l’aspect technique des croyances magiques, mais aussi en essayant de cerner la « personnalité » du magicien, sa puissance ainsi que les différentes contraintes qui entourent ses fonctions sociales.
Derrière l’imposture de la « science » économique, il y a l’impasse du capitalisme
Authors: Harribey Jean-Marie
Published: June 2015

Le livre de l’économiste australien Steve Keen, L’Imposture économique , vient d’être traduit en français. Il offre un panorama synthétique de la critique méthodologique que l’on peut faire de la théorie néoclassique. D’abord, il déconstruit tous les fondements de celle-ci : loi de l’offre et de la demande, concurrence parfaite, répartition des revenus à la productivité marginale, etc. Ensuite, l’auteur examine pourquoi la théorie néoclassique est incapable d’expliquer et, a fortiori , de prévoir les crises. À la racine de cette incapacité, il y a l’incompréhension du phénomène monétaire. Keen propose alors une interprétation s’inscrivant dans le sillage de Marx, Keynes et surtout Minsky pour saisir l’origine de la crise actuelle, déclenchée par l’emballement du crédit organisé par une finance débridée, et ayant entraîné une « Grande récession ». Un livre remarquable, malgré une relative faiblesse pour intégrer économie et rapports sociaux.

Polarization Characteristics to Wear Ratio of Anti-Fouling Paint
Authors: Moon Kyung Man , Park Dong Hyun , Kim Yun Hae , Baek Tae Sil
Published: June 2015

Recently, anti-fouling paints which does not include the poison components such as tin (Sn) free, copper (Cu) free have been increasingly developed in order to decrease the contamination of marine environment. Moreover, the wear ratios of these anti-fouling paints are very important problem to prolong their life time in economical and environmental point of view. In this study, four types of anti-fouling paints as self-polishing type were investigated on the relationship between their polarization characteristics and wear ratios. Relationship between wear ratio and variation ratio of polarization resistance measured in corrosion potential was not well matched with each other. However, there was a good agreement between the wear ratio and variation ratio of diffusion limiting current density, for example, the higher or the lower variation ratio of diffusion limiting current density, wear ratio also increased or decreased respectively. Consequently, it is suggested that we can qualitatively expect the life time and wear degree of anti-fouling paint by only measuring the polarization characteristics before the wear test is practically performed in the field.Keywords: Anti-fouling paint, Self-polishing type, Polarization characteristics, Wear ratio, Diffusion limiting current density, Corrosion Potential
Effect of Temperature on Optical and Photovoltaic Properties of nc-TiO2 Thin Films for Dye Sensitized Solar Cell
Authors: Sarode M.T. , Khollam Y.B. , Jadkar S.R. , Kale B.B. , Mohite K.C.
Published: June 2015

In this investigation, anatase nanocrystalline TiO2 (nc-TiO2) films are deposited by using sol-gel dip coating method on ITO substrates followed by annealing at 200, 300, 400 and 500 °C / 2 hr in air. To examine the structure and morphology of films, XRD, Raman spectroscopy, SEM and HRTEM techniques are used. The XRD studies showed the evolution of pure anatase TiO2 phase with average crystallite size = 12-15 nm in resultant films. The morphological studies using SEM and HRTEM indicated ~ uniform size distribution of spherical agglomerates in films and nanocrystalline state of films (average particle size ~ 20 nm) respectively. The optical properties calculated from UV-Visible transmission spectra are found to be indirect band gap energy = 3.20 eV, absorbance coefficient = 9.2 x 104 cm-1, transmittance = 88.5 %, refractive index = 2.12 and porosity ratio = 36.6 % for the 400 °C annealed film. The better photovoltaic performance: JSC = 2.34 mA/cm2, VOC = 0.562V, FF = 35.23 % & η = 0.46 % is obtained for eosin-Y dye sensitized solar cell made with 400 °C annealed film.
Spectroscopic Ellipsometry Study on Strain Evolution of Transparent Conductive Thin Films Prepared by RF Sputtering Method
Authors: Lin Keh Moh , Lee Yang Hsien , Huang Wen Yeong , Hsieh Ching Tsun , Hsu Chih Kai
Published: June 2015

In this study, AZO films were deposited by RF sputtering technique. Then, the state of residual stress in the AZO films was investigated by using spectroscopic ellipsometry (SE) and XRD methods. Our experiments show that a suitable SE model could provide useful indication about the variation of stress in the as-deposited films. However, there is a disparity in the results of the SE fitting and XRD stress analysis for annealed AZO films. Further investigation is required in order to understand the cause of this contradiction. Despite this disparity, the SE technique enables us to monitor strain relaxation in TCO films with a faster and simpler way compared with other methods.
Effect on the Flow Properties of the Mortar Using Micro-Nano Bubbles
Authors: Maruyama Takayoshi , Takahashi Naoya , Hashimoto Shinchiro , Date Shigeyuki
Published: June 2015

Bubble of which diameter ranges 50μm to nanometer-order is called micro-nanobubble (here in after “MNB”), it has properties different from the millimeter-order and centimeter-order naturally generated. In general, the bubble rises rapidly in water and burst at the surface. However, the MNB tends to stay in the water as the diameter of itself becomes small. In addition, MNB has various characteristics unlike general water. A typical characteristic includes water purification effect, and is utilized such as water treatment, agricultural industry and chemical industry. However, there is not much report that was utilized in the construction sector so far. In this study, it paid attention to the feature of MNB that the resistance when flowing in the tube decreases, and the possibility of the workability improvement of the grout material and the filling material by the use of MNB was investigated by the experiment of the cement paste. As the results, when it compared properties of the paste that used both MNB and tap water, no difference was observed in the air content and the flow value. However, plastic viscosity of the paste that used MNB was smaller than control paste. In consequence it was confirmed that the flow speed of the paste when it flows in the pipe was improved.

The controlled solution spray process with superior molecular contacting between finely atomized reactants in impinging solution spray reactor was carried out with an objective to develop the nonionic surfactant (Tween-80) mediated coprecipitation protocol for the polymorph selective synthesis of lead chrome (PbCrO4) nanocrystals. Monoclinic PbCrO4 nanorods with size in the range of 37.8-51.9 nm at Tween-80 loadings of 2-10 g/L were obtained. The functional group, surfactant adsorption, crystal type, size and morphology of the PbCrO4 nanocrystals were determined by FTIR, XRD and FESEM analysis.

From the viewpoint of effective utilization of industrial wastes and reduction of CO2 emission, the use of concrete mixed with blast furnace slag and fly ash has been promoted. However, the durability of fly ash concrete using blast furnace slag cement has not been clarified enough. About chloride attack, the resistance against the penetration of chloride ions could be improved due to the dense pore structure formed by the synegetic effect of mixing both ground granulated blast-furnace slag and fly ash into concrete. In this study, resistance performance of concrete using both blast furnace slag cement and fly ash against chloride attack and carbonation was experimentally investigated. The relationship between such resistance performance and pore structure of the concrete was also examined. As a result, the combination of blast furnace slag cement and fly ash type II resulted in the decrease of pore volume over 50 nm in the diameter and reduction of the apparent diffusion coefficient of chloride ion, but the resistance performance against carbonation of the concrete was lower than the case of the normal fly ash concrete.

The hydrophobic effect on electrodeposition of an enzyme CotA was investigated. The CotA was electrodeposited on a gold disc electrode modified with an alkane thiol self-assembled monolayer (SAM). The CotA immobilized hydrophobic SAM gold electrodes exhibited a larger electrochemical activity compared with the hydrophilic SAM and bare electrodes. In particular, large current responses were observed in an ethanethiol or a 1-butanethiol SAM gold electrode. In addition, effect of addition of non-ionic surfactant Triton X on the electrodeposition was checked using the SAM gold electrode. The addition of Triton X had a positive effect on the electrodeposition.

We investigated the efficient use of cellulose to resolve the problem of the depletion of fossil resources. In this study, as the biomass material, the green composite based on natural rubber (NR) and the flake-shaped cellulose particles (FSCP) was produced. Moreover, in order to improve vibration-damping and O2 barrier properties, NR and epoxidized natural rubber (ENR) blends were also used. In addition, butyl rubber (IIR) was used as a target of damping or gas-barrier materials. Vibration-damping and O2 barrier properties of the composite including FSCP was increased with increasing ENR content. In particular, we found that ENR-50 composite containing 50 phr FSCP has higher vibration-damping property than IIR composite containing 50 phr carbon black.

There is a continuous demand for next-generation industrial materials because they offer advantages such as high performance, reliable life cycle, reasonable cost, and ease of mass production. Carbon nanotubes (CNTs), which possess unique properties such as beneficial mechanical, electrical, and thermal properties, as well as chemical stability, have received considerable attention as candidates for reinforcing ultra-high-performance nanocomposites. CNT-reinforced Al alloy matrix nanocomposites were fabricated by mechanical ball-milling and hot-pressing processes. The effects of different CNTs on the mechanical properties of the composites were investigated. The mechanical properties were found to change significantly depending on the type of CNT blended with the matrices. The mechanical performance of the nanocomposites can thus be controlled by using different types of CNT reinforcements.
Adamantane-Modified Polyurethanes: Effect of Hydroxy Group of Adamantane on the Properties of Polyurethanes
Authors: Lau Ze Ren , Sin Sau Leng , Yan Hong , Xu Jian Wei
Published: June 2015

The paper describes synthesis and characterization of adamantane-modified polyurethanes (PU). The study shows that the number of hydroxy groups of adamantane additives plays a signifiant role in tuning polyurethane's properties. PU modified with adamantanetriol has relatively higher glass transition temperature than these with adamantanediol as an additive. Dynamic mechanical analysis (DMA) of PU with 0.5% adamantanetriol shows significant improvement in storage modulus and larger hardness than pure PU at low temperatures. In contrast, adamantanediol-modified PU exhibits lower storage modulus and smaller hardness than pure PU film. These remarkabe differences between two types of admantane-modified PUs originate from the low reactivity of adamantanediol as well as the formation of crosslinked structures in the presence of adamantanetriol.

Coevolution of ticks and the vertebrate immune system has led to the development of immunosuppressive molecules that prevent immediate response of skin-resident immune cells to quickly fend off the parasite. In this article, we demonstrate that the tick-derived immunosuppressor sialostatin L restrains IL-9 production by mast cells, whereas degranulation and IL-6 expression are both unaffected. In addition, the expression of IL-1β and IRF4 is strongly reduced in the presence of sialostatin L. Correspondingly, IRF4- or IL-1R–deficient mast cells exhibit a strong impairment in IL-9 production, demonstrating the importance of IRF4 and IL-1 in the regulation of the Il9 locus in mast cells. Furthermore, IRF4 binds to the promoters of Il1b and Il9, suggesting that sialostatin L suppresses mast cell–derived IL-9 preferentially by inhibiting IRF4. In an experimental asthma model, mast cell–specific deficiency in IRF4 or administration of sialostatin L results in a strong reduction in asthma symptoms, demonstrating the immunosuppressive potency of tick-derived molecules.

Because of significant viral diversity, vaccines that elicit durable and broad protection against influenza have been elusive. Recent research has focused on the potential of highly conserved regions of the viral hemagglutinin (HA) as targets for broadly neutralizing Ab responses. Abs that bind the highly conserved stem or stalk of HA can be elicited by vaccination in humans and animal models and neutralize diverse influenza strains. However, the frequency and phenotype of HA stem–specific B cells in vivo remain unclear. In this article, we characterize HA stem–specific B cell responses following H5N1 vaccination and describe the re-expansion of a pre-existing population of memory B cells specific for stem epitopes. This population uses primarily, but not exclusively, IGHV1-69–based Igs for HA recognition. However, within some subjects, allelic polymorphism at the ighv1-69 locus can limit IGHV1-69 immunodominance and may reduce circulating frequencies of stem-reactive B cells in vivo. The accurate definition of allelic selection, recombination requirements, and ontogeny of neutralizing Ab responses to influenza will aid rational influenza vaccine design.

Individuals with unilateral hearing loss of severe-profound degree face listening difficulties while localizing a sound source and while perceiving speech in the presence of noise. The objective was to compare the efficacy of the digitally programmable bone anchored hearing aid (BAHA), trimmer digital BAHA and the transcranial contralateral routing of signal (T-CROS) in improving the listening performance in adults with unilateral hearing loss. Twenty-four adults with unilateral hearing loss was assessed for sound field thresholds, speech perception performance in quiet and noise (direct and indirect conditions) and the subjective quality rating of speech in unaided and aided with either T-CROS or digitally programmable BAHA or trimmer digital BAHA attached to the headband. Results indicated that the participants performed better with both the digitally programmable and the trimmer digital BAHA than the T-CROS in both quiet and noise. However, the digitally programmable BAHA performed better when the speech arrived from the poorer ear side. The current study helps in prioritizing the hearing amplification devices for the trial and also helps in arriving at the appropriate hearing amplification device for the individuals with unilateral hearing loss.

Authors: Campobasso Gaetano , Colonnelli Enzo , Mc Neel Hank
Published: June 2015

A survey conducted in central Italy found 126 species of phytophagous insects from five orders and 25 families on dyer’s woad, Isatis tinctoria L., a biennial or short-lived perennial. About 75% of the species found attacking this weed were polyphagous, 20% were restricted to the family Brassicaceae, and only 5% were restricted to the genus Isatis. Four of the one hundred twenty six species recovered were specific enough to merit further research as candidates for biological control of I. tinctoria L. in the United States. Preliminary host range tests were conducted for the weevils Ceutorhynchus rusticus Gyllenhal, Ceutorhynchus peyerimoffi Hustache, Aulacobaris fallax (H. Brisout), and the fleabeetle Psylliodes isatidis Heikertinger. All tests were conducted at the USDA-ARS-EBCL Rome substation from 2003 to 2006 and are reported herein.

The document is based on consensus among the experts and best available evidence pertaining to Indian population and is meant for practice in India.All postcholecystectomy gallbladder specimens should be opened and examined carefully by the operating surgeon and be sent for histopathological examination.All "incidental" gall bladder cancers (GBCs) picked up on histopathological examination should have an expert opinion.Evaluation of a patient with early GBC should include essential tests: A computed tomography (CT) scan (multi-detector or helical) of the abdomen and pelvis for staging with a CT chest or chest X-ray, and complete blood counts, renal and liver function tests. magnetic resonance imaging/positron emission tomography (PET)-CT are not recommended for all patients.For early stage disease (up to Stage IVA), surgery is recommended. The need for adjuvant treatment would be guided by the histopathological analysis of the resected specimen.Patients with Stage IVB/metastatic disease must be assessed for palliative e.g. endoscopic or radiological intervention, chemotherapy versus best supportive care on an individual basis. These patients do not require extensive workup outside of a clinical trial setting.There is an urgent need for multicenter trials from India covering various aspects of epidemiology (viz., identification of population at high-risk, organized follow-up), clinical management (viz., bile spill during surgery, excision of all port sites, adjuvant/neoadjuvant therapy) and basic research (viz., what causes GBC).
