Une transition thématique dans les STS ?
Authors: Vessuri Hebe 
Published: July 2017

Le monde semble s’intégrer de plus en plus, ouvrant d’autant plus de possibilités d’actions collectives. Toute une série de biens publics tels que la paix mondiale, la santé, la protection de l’environnement, la connaissance globale, doivent être protégés parce que si la communauté internationale ne s’en occupe pas collectivement, il est probable qu’ils seront perdus. Les grands acteurs de l’entreprise concentrent une partie importante de la richesse mondiale ; ils pourraient aider à assurer ces biens publics mondiaux. L’article se penche sur la relation entre le secteur des grandes entreprises multinationales et les Nations Unies et ce que cela implique pour l’avenir des biens mondiaux et pour l’Agenda 2030.
Les acteurs européens de la circulation des normes dans le secteur de l’emploi
Authors: Arrignon Mehdi 
Published: July 2017

Résumé L’article étudie les acteurs et les mécanismes de la circulation européenne des normes en matière de politique de l’emploi. Prenant pour espace d’analyse les rencontres européennes du Mutual Learning Programme , l’article aborde des questionnements classiques de sociologie du pouvoir: qui fixe l’agenda ? Quels intervenants sont ciblés ? Et par qui ? Sur quelles bases se réalisent les échanges ? Quelle est la place des acteurs institutionnels de l’Union européenne (UE) dans le processus ? L’enquête sur laquelle est basée l’article renseigne sur les positions et les relations de pouvoir spécifiques des acteurs intervenant dans le processus de circulation des normes. L’article montre finalement que l’organisation des échanges européens n’est pas aussi souple et horizontale que le projet de « coordination ouverte » le suppose: le Mutual Learning Programme renforce des logiques d’asymétrie entre les différents acteurs de la coordination européenne.
La gestion intégrée des frontières : circulation et projection internationale d’un « modèle » européen. L’exemple de la Turquie
Authors: Le Chêne Elen 
Published: July 2017

Résumé Cet article s’intéresse au modèle de Gestion Intégrée des Frontières (GIF). Élaboré par l’Union européenne dans les années 2000, il fait rapidement l’objet d’une circulation intense au-delà des frontières de l’UE. La Turquie représente à cet égard un terrain clé de diffusion. Des experts de différentes institutions y promeuvent des savoirs et savoir-faire dans le secteur de la gestion des frontières. Des divisions internes au monde de la GIF se réactualisent alors au cours du travail d’import-export d’expertise. Cela entraîne des effets sur les « bonnes pratiques » valorisées pour réformer la gestion des frontières et, en définitive, sur la construction d’un modèle GIF hors de l’UE.
Sur « l’ONGisation des mouvements sociaux » : dépolitisation de l’engagement ou évitement du social ?
Authors: Moallic Benjamin 
Published: July 2017

Comment analyser la multiplication sans précédent d’associations, de fondations et d’organisations non gouvernementales (ONG) dans le Salvador de la fin des années 1980, et que nous disent ces phénomènes des mutations à l’œuvre dans les milieux militants centraméricains ? Partant des récits d’anciens cadres du Front Farabundo Martí de libération nationale (FMLN) et de témoignages sur l’évolution des communautés de réfugiés salvadoriens, nous interrogeons la notion « d’ONGisation des mouvements sociaux » aujourd’hui employée pour expliquer la multiplication des associations en Amérique centrale. À distance des analyses en termes de « dépolitisation », nous montrons que ce qui est en jeu dans l’ONGisation des mouvements sociaux procède moins d’une délégitimation des conflits sociaux que de l’invention d’un nouveau mode de prise en charge, permettant de lier ensemble une dépendance inhérente au militantisme à une exigence nouvelle d’égalité ; modalité qui suppose moins la fragmentation des couches populaires que leur « évitement ».
Reconversion d’un savoir militant en expertise étatique : l’exemple des réformes autour de la sécurité en Argentine
Authors: Martinez Candice 
Published: July 2017

En Argentine, la transition démocratique voit émerger sur la scène publique un ensemble d’acteurs mobilisés pour une « démocratisation » des institutions policières et pénales. Leurs revendications ne seront pas entendues jusqu’à la fin des années 1990. Dans un contexte de montée de l’insécurité, le gouvernement fédéral adopte un plan de prévention de la délinquance qui affiche l’objectif de « démocratiser le gouvernement de la sécurité » afin de mener une politique « plus respectueuse des droits de l’homme ». Comment expliquer cette référence à la démocratisation et aux droits humains ? En retraçant les trajectoires biographiques des acteurs à l’origine de ce plan, notre article décrit la reconversion de savoirs universitaires-militants en savoirs d’État.
Partial anomalous hepatic venous drainage into left-sided atrium with right isomerism: A case report with review of literature
Authors: Kumar Ishan , Bhatia Anmol , Sodhi Kushaljit S , Khandelwal Niranjan 
Published: July 2017

AbstractRight isomerism, also known as Ivemark syndrome, is an unusual degree of symmetry of some of the abdominothoracic viscera reflecting bilateral right-sidedness. We report an exceedingly rare occurrence of anomalous drainage of the left hepatic vein to the left-sided atrium in a patient of right isomerism. With this case report, we further endorse that the isomerism of atrium might extend beyond the appendages, a view that has been long dismissed by the existing literature.
Differentiation of secondary involvement of the breast by lymphoreticular malignancy from fibroadenoma using ultrasound elastography: A report of two cases
Authors: Abdulkadir Eren , Gulhan Ertan , Ulus Sila 
Published: July 2017

AbstractExtramedullary lymphoma infiltration of the breast by lymphoblastic lymphoma is very rare and most cases are of B-cell lineage; T-cell neoplasms represent less than 10% of all breast lymphomas. Here, we report one patient with lymphoblastic lymphoma and one patient with leukemia, who have similar lesions in breasts with different ultrasound elastography findings. Ultrasound-guided tru-cut biopsies were performed and the first lesion was confirmed as lymphoma infiltration and the second as fibroadenoma. In cases of breast mass presence in patients with a history of hematologic malignancies such as lymphoma or leukemia, breast infiltration should be kept in mind. Elastography findings can assist in the differentiation of these lesions and further investigations or biopsies can be avoided.
Sequential MR imaging (with diffusion-weighted imaging) changes in metronidazole-induced encephalopathy
Authors: Singh Rupinder , Kaur Ramanjeet , Pokhariyal Pawan , Aggarwal Rajul 
Published: July 2017

AbstractMetronidazole-induced neuro-toxicity, though rare, is known. A characteristic spatial distribution of lesions in cerebellar dentate nuclei and dorsal pons is known. However, temporal progression of lesions on magnetic resonance imaging (MRI) has not been described previously. We describe two such cases which presented initially with splenial hyperintesity and showed progression to characterstic lesions. Both cases improved with stoppage of metronidazole.
Imaging features of vascular compression in abdomen: Fantasy, phenomenon, or true syndrome
Authors: Srisajjakul Sitthipong , Prapaisilp Patcharin , Bangchokdee Sirikan 
Published: July 2017

AbstractVascular structures in the abdomen can compress or be compressed by adjacent structures. Classic imaging findings of vascular compressions, including median arcuate ligament syndrome, superior mesenteric artery syndrome, nutcracker syndrome, portal biliopathy, May-Thurner syndrome, and ureteropelvic junction obstruction will be discussed here. It is important to correlate imaging findings and clinical data to identify asymptomatic vascular compression which requires no treatment, intermittent vascular compression with nonspecific or vague clinical manifestation, and the subset of patients with true syndromes who will benefit from treatment.
Radiation Safety: Endodontic Perspective
Authors: Prasanth Dhanapal T , Joy Manayanipuram Noble , Anna Cherian Anuja 
Published: July 2017

ABSTRACT
Endodontists belong to the category of specialist dentists who depend much on dental radiography. Starting from the stage of disease diagnosis, radiography is of much importance in different stages of endodontic therapy, and further on radiographic evaluation is a tool for assessment of endodontic treatment. There is a heavy dependency on dental radiography in some form or other in the speciality of endodontics. As is the case with any ionizing radiation, radiation hazard is a phenomenon that matters a lot to this group of dental professionals. There needs to be a change in our attitude toward radiation safety measures, as many of our professional colleagues are seen much not to be bothered about the cumulative outcomes of radiation hazard, which can create havoc in our professional and personal lives. This article outlines the potential hazards that can happen by routine radiographic utilization in endodontic setup and tries to highlight the measures that need to be taken to mitigate the negative effects.

Management of an Anterior Tooth with External and Internal Resorption
Authors: Anilkumar Aadit , Nazar Faisal , Rajendran Ratheesh 
Published: July 2017

ABSTRACT
Tooth resorption is a condition associated with either a physiologic or a pathologic process resulting in a loss of dentin, cementum, and/or bone. Inflammatory process is initiated when the predentin or precemental layer of the tooth is damaged. Resorption can either be external or internal in form. In order to control the tooth resorption, it is necessary to treat the root canal by removing all the pulp tissue. Due to varied root canal morphology, root canal treatment poses a challenge for the clinician. In such cases a combination of conventional lateral compaction and thermoplasticized gutta percha can enable the three-dimensional obturation of the canal space. This case report describes a nonsurgical mode of management of a tooth having internal and external (surface) resorption.

Abstract. Land use change (deforestation) has several negative consequences for the soil system. It is known to increase erosion rates, which affect the distribution of elements in soils. In this context, the crucial nutrient Si has received little attention, especially in a tropical context. Therefore, we studied the effect of land conversion and erosion intensity on the biogenic silica pools in a subtropical soil in the south of Brazil. Biogenic silica (BSi) was determined using a novel alkaline continuous extraction where Si ∕ Al ratios of the fractions extracted are used to distinguish BSi and other soluble fractions: Si ∕ Al > 5 for the biogenic AlkExSi (alkaline-extractable Si) and Si ∕ Al < 5 for the non-biogenic AlkExSi. Our study shows that deforestation can rapidly (< 50 years) deplete the biogenic AlkExSi pool in soils depending on the slope of the study site (10–53 %), with faster depletion in steeper sites. We show that higher erosion in steeper sites implies increased accumulation of biogenic Si in deposition zones near the bottom of the slope, where rapid burial can cause removal of BSi from biologically active zones. Our study highlights the interaction of erosion strength and land use for BSi redistribution and depletion in a soil toposequence, with implications for basin-scale Si cycling.

Abstract. Albedo is a fundamental parameter in earth sciences, and many analyses utilize the Moderate Resolution Imaging Spectroradiometer (MODIS) bidirectional reflectance distribution function (BRDF)/albedo (MCD43) algorithms. While derivative albedo products have been evaluated over Greenland, we present a novel, direct comparison with nadir surface reflectance collected from an unmanned aerial system (UAS). The UAS was flown from Summit, Greenland, on 210 km transects coincident with the MODIS sensor overpass on board the Aqua and Terra satellites on 5 and 6 August 2010. Clear-sky acquisitions were available from the overpasses within 2 h of the UAS flights. The UAS was equipped with upward- and downward-looking spectrometers (300–920 nm) with a spectral resolution of 10 nm, allowing for direct integration into the MODIS bands 1, 3, and 4. The data provide a unique opportunity to directly compare UAS nadir reflectance with the MODIS nadir BRDF-adjusted surface reflectance (NBAR) products. The data show UAS measurements are slightly higher than the MODIS NBARs for all bands but agree within their stated uncertainties. Differences in variability are observed as expected due to different footprints of the platforms. The UAS data demonstrate potentially large sub-pixel variability of MODIS reflectance products and the potential to explore this variability using the UAS as a platform. It is also found that, even at the low elevations flown typically by a UAS, reflectance measurements may be influenced by haze if present at and/or below the flight altitude of the UAS. This impact could explain some differences between data from the two platforms and should be considered in any use of airborne platforms.
Sila nestálosti: volatilita voličov na Slovensku vo voľbách 2016
Authors: Gyárfášová Oľga , Bahna Miloslav , Slosiarik Martin 
Published: July 2017

Electoral behavior in Slovakia is characterized by high instability. The study identifies the level of aggregated and individual volatility from a historical perspective, focusing specifically on the 2016 general election. Based on exit-poll data, it argues that the traditional mainstream parties (KDH, SDKU, which failed to surpass the 5% threshold, and also Smer-SD) have lost many of their loyal core voters. The beneficiaries of voter mobility were the new anti-system parties – above all, We Are A Family and the extreme-right People’s Party Our Slovakia (ĽSNS). The paper identifies a specific segment of the electorate – voters who abstained in 2012 but were mobilized for the more recent election. It argues that as the turnouts were about the same in 2012 and 2016, other segments of voters were mobilized in the 2016 election. The fact that a large proportion of these voters decided for the parties We Are A Family and ĽSNS means that they were effectively addressed by a protest, anti-establishment alternative. Based on exit-poll data, the study argues that the level of abstention in the 2012 general election (excluding first-time voters) was the strongest predictor of voter preference for these two parties. Moreover, the extreme-right ĽSNS has been very successful in attracting first-time voters.

Published: July 2017

The use of violent video-games among teenagers is becoming undisputed. The goal of this study is identifying the video-game typology played by teenagers in two most important High Schools in the two most important cities of Albania and present the effect of this video-games. There were twenty-six participants in this study, all students in the tenth grade. Of these selected students, sixteen were boys and ten were girls. For selecting the participants in the study, it was used the accidental sampling method and for the data collection it was used the semi-structured interviews. Thematic analysis is used to analyze the data collected. One of the most interesting findings of this study is that the use of violent video-games can cause a remodeling in teenager’s behavior, accompanied by a psychological vitality, which in many cases could be negative, especially when this experience is direct. The study doesn’t have a generalizing character.

Published: July 2017

AbstractAn efficient and facile method for the Paal–Knorr furan synthesis using titanium tetrachloride as dehydrating agent is described. Tricarbonyl compounds, prepared through the nucleophilic substitution of α‐halogenated ketones and β‐dicarbonyl compounds, are easily condensed to their corresponding polysubstituted furans. The reaction also occurs efficiently with tetracarbonyl compounds derived by dimerization of β‐dicarbonyl compounds.

Anderson Localization for Very Strong Speckle Disorder
Authors: Hilke M. , Eleuch H. 
Published: July 2017

AbstractWe evaluate the localization length of the wave (or Schrödinger) equation in the presence of a disordered speckle potential. This is relevant for experiments on cold atoms in optical speckle potentials. We focus on the limit of large disorder, where the Born approximation breaks down and derive an expression valid in the “quasi‐metallic” phase at large disorder. This phase becomes strongly localized and the effective mobility edge disappears.
Fabrication of Mesoporous‐Silica‐Coated Upconverting Nanoparticles with Ultrafast Photosensitizer Loading and 808 nm NIR‐Light‐Triggering Capability for Photodynamic Therapy
Authors: Han Renlu , Shi Junhui , Liu Zongjun , Wang Hao , Wang You 
Published: July 2017

AbstractA novel photodynamic therapy nanoplatform based on mesoporous‐silica‐coated upconverting nanoparticles (UCNP) with electrostatic‐driven ultrafast photosensitizer (PS) loading and 808 nm near infrared (NIR)‐light‐triggering capabilities has been fabricated. By positively charging inner channels of the mesoporous silica shell with amino groups, a quantitative dosage of negatively charged PS, exemplified with Rose Bengal (RB) molecules, can be loaded in 2 min. In addition, the electrostatic‐driven technique simultaneously provides the platform with both excellent PS dispersity and leak‐proof properties due to the repulsion between the same‐charged molecules and the electrostatic attraction between different‐charged PS and silica channel walls, respectively. The as‐coated silica shell with an ultrathin thickness of 12±2 nm is delicately fabricated to facilitate ultrafast PS loading and efficient energy transfer from UCNP to PS. The outside surface of the silica shell is capped with hydrophilic β‐cyclodextrin, which not only enhances the dispersion of resulting nanoparticles in water but also plays a role of “gatekeeper”, blocking the pore opening and preventing PS leaking. The in vitro cellular lethality experiment demonstrates that RB molecules can be activated to effectively generate singlet oxygen and kill cancer cells upon 808 nm NIR light irradiation.
Ruthenium‐Catalyzed Deaminative Hydrogenation of Aliphatic and Aromatic Nitriles to Primary Alcohols
Authors: Molnár István Gábor , Calleja Pilar , Ernst Martin , Hashmi A. Stephen K. , Schaub Thomas 
Published: July 2017

AbstractThe deaminative hydrogenation of nitriles towards alcohols is a useful reaction to transform nitriles into alcohols with NH3 as the sole byproduct. Using the simple and robust RuHCl(CO)(PPh3)3 complex as a catalyst, at low H2 pressures a series of aliphatic and aromatic nitriles could be transformed into the corresponding alcohols. Suitable solvent systems for these reactions were 1,4‐dioxane/water and EtOH/water mixtures. In most cases, the selectivity for the alcohols was excellent, and the corresponding amines were formed only in trace amounts.
Enhanced Electrochemical Performance of Mesocarbon‐Microbeads‐Based Anodes through Air Oxidation for Sodium‐Ion Batteries
Authors: Yuan Chao , Zhu Youyu , Zhao Pinyi , Yu Baojun , Li Qi , Wang Chengyang 
Published: July 2017

AbstractAir oxidation is introduced as a simple and feasible method of modification for mesocarbon microbeads (MCMBs), which improves the electrochemical performance of MCMBs as anodes for sodium‐ion batteries (SIBs). Optimal oxidation conditions are explored. Green MCMBs, initially oxidized at 360 °C then carbonized (OC‐MCMB360), exhibit a high reversible capacity up to 286 mAh g−1 at a current density of 25 mA g−1. In addition, the OC‐MCMB360 sample also presents an excellent rate performance with 79 mAh g−1 at a current density of 3.2 A g−1 and a considerable reversible capacity of 166 mAh g−1 after 100 cycles at 100 mA g−1. The larger interlayer spacing and increased defect sites caused by oxidation contribute to the enhanced electrochemical performance of oxidized MCMBs in SIBs.

Authors: Zhou Jie , Yao Hanchun , Meng Lingchang , Sun Chong , Ye Weiran , Du Qiuzheng 
Published: July 2017

AbstractTo develop a multifunctional nanomaterial for dual‐mode imaging and synergetic chemotherapy, curcumin (CUR) was physically entrapped into hollow upconversion NaGdF4 nanomaterial, then apoferritin (AFn) loaded with doxorubicin (DOX) was attached to the NaGdF4 surface. Subsequent modification with the targeting reagent folic acid (FA) led to generation of the CUR/NaGdF4–DOX/AFn–FA conjugate for cancer treatment. X‐ray diffraction, scanning (SEM) and transmission electron microscopy (TEM), and Fourier transform infrared (FTIR) spectroscopy demonstrated the successful preparation of hexagonal‐phase NaGdF4 and NaGdF4–AFn–FA. Moreover, no toxicity was observed for NaGdF4–AFn–FA. In vitro and in vivo experiments demonstrated that the two drugs are sequentially released from the nanocomposites. This two‐drug system showed strong growth inhibitory effects on MCF‐7 cells. Upconversion luminescence imaging and magnetic resonance (MR) imaging of NaGdF4–AFn–FA were carried out. The results of this study show that NaGdF4–AFn–FA can be used for targeted anticancer drug delivery as well as imaging, a novel multi‐pronged theranostic system for tumor treatment.
