Authors: Ramadan M.K. , Hussein G. , Saheb W. , Rajab M. , Mirza F.G. 
Published: March 2016

OBJECTIVE: The study objective was to examine the effect of antenatal corticosteroids on the incidence of short-term neonatal morbidities in singletons born during the late preterm period. STUDY DESIGN: This was a prospective cohort study of singleton gestations at risk of imminent delivery between 34 0/7 and 36 6/7 weeks. Short-term neonatal morbidities were compared between the corticosteroid exposed and non-exposed groups. The rates of Neonatal Morbidity Composite and Any Adverse Neonatal Morbidity were then compared between the two groups. RESULTS: During the two-year study period, a total of 295 subjects were included. Of those, 74 were exposed to antenatal corticosteroids, while 221 cases constituted the non-exposed group. There was no statistically significant difference in the rate of Any Adverse Neonatal Morbidity (47.3% vs. 40.7% , p = 0.32) or the rate of Neonatal Morbidity Composite (34.4% vs. 37.8% , p = 0.59) between the two groups. Additionally, there was no statistically significant difference in the rates of neonatal intensive care unit admission, respiratory distress syndrome, transient tachypnea of the newborn, hypothermia, and need for phototherapy. CONCLUSION: Administration of antenatal corticosteroids to parturients at risk of imminent delivery during the late preterm period does not appear to reduce short-term neonatal morbidities.
A NEW ANALYSIS OF THE TWO CLASSICAL ZZ CETI WHITE DWARFS GD 165 AND ROSS 548. II. SEISMIC MODELING
Authors: Giammichele N. , Fontaine G. , Brassard P. , Charpinet S. 
Published: March 2016

ABSTRACT
We present the second of a two-part seismic analysis of the bright, hot ZZ Ceti stars GD 165 and Ross 548. In this second part, we report the results of detailed searches in parameter space for identifying an optimal model for each star that can account well for the observed periods, while being consistent with the spectroscopic constraints derived in our first paper. We find optimal models for each target that reproduce the six observed periods well within ∼0.3% on the average. We also find that there is a sensitivity on the core composition for Ross 548, while there is practically none for GD 165. Our optimal model of Ross 548, with its thin envelope, indeed shows weight functions for some confined modes that extend relatively deep into the interior, thus explaining the sensitivity of the period spectrum on the core composition in that star. In contrast, our optimal seismic model of its spectroscopic sibling, GD 165 with its thick envelope, does not trap/confine modes very efficiently, and we find weight functions for all six observed modes that do not extend into the deep core, hence accounting for the lack of sensitivity in that case. Furthermore, we exploit after the fact the observed multiplet structure that we ascribe to rotation. We are able to map the rotation profile in GD 165 (Ross 548) over the outermost ∼20% (∼5%) of its radius, and we find that the profile is consistent with solid-body rotation.
FARGO3D: A NEW GPU-ORIENTED MHD CODE
Authors: Benítez-Llambay Pablo , Masset Frédéric S. 
Published: March 2016

ABSTRACT
We present the FARGO3D code, recently publicly released. It is a magnetohydrodynamics code developed with special emphasis on the physics of protoplanetary disks and planet–disk interactions, and parallelized with MPI. The hydrodynamics algorithms are based on finite-difference upwind, dimensionally split methods. The magnetohydrodynamics algorithms consist of the constrained transport method to preserve the divergence-free property of the magnetic field to machine accuracy, coupled to a method of characteristics for the evaluation of electromotive forces and Lorentz forces. Orbital advection is implemented, and an N-body solver is included to simulate planets or stars interacting with the gas. We present our implementation in detail and present a number of widely known tests for comparison purposes. One strength of FARGO3D is that it can run on either graphical processing units (GPUs) or central processing units (CPUs), achieving large speed-up with respect to CPU cores. We describe our implementation choices, which allow a user with no prior knowledge of GPU programming to develop new routines for CPUs, and have them translated automatically for GPUs.
CENTRAL ENGINE MEMORY OF GAMMA-RAY BURSTS AND SOFT GAMMA-RAY REPEATERS
Authors: Zhang Bin-Bin , Zhang Bing , Castro-Tirado Alberto J. 
Published: March 2016

ABSTRACT
Gamma-ray bursts (GRBs) are bursts of γ-rays generated from relativistic jets launched from catastrophic events such as massive star core collapse or binary compact star coalescence. Previous studies suggested that GRB emission is erratic, with no noticeable memory in the central engine. Here we report a discovery that similar light curve patterns exist within individual bursts for at least some GRBs. Applying the Dynamic Time Warping method, we show that similarity of light curve patterns between pulses of a single burst or between the light curves of a GRB and its X-ray flare can be identified. This suggests that the central engine of at least some GRBs carries “memory” of its activities. We also show that the same technique can identify memory-like emission episodes in the flaring emission in soft gamma-ray repeaters (SGRs), which are believed to be Galactic, highly magnetized neutron stars named magnetars. Such a phenomenon challenges the standard black hole central engine models for GRBs, and suggest a common physical mechanism behind GRBs and SGRs, which points toward a magnetar central engine of GRBs.

L’application de la responsabilité de protéger en Libye : retour à la case départ ?
Authors: Ben Lamma Mohammed Faraj 
Published: March 2016

Depuis la fin de la Seconde Guerre mondiale, la doctrine de l’intervention humanitaire a fait l’objet d’un débat permanent au sein des Nations unies, des États, de la communauté des chercheurs et de la société civile. Au cœur de cette controverse, la tension entre deux principes fondamentaux du droit international : d’une part, l’interdiction de l’usage de la force ; d’autre part, l’obligation de respecter et de protéger les droits de l’homme. Dix ans après la publication par la CIISE d’un important rapport sur la responsabilité de protéger (R2P) et six ans après son entrée dans le champ juridique international, la R2P a connu une application concrète : à l’occasion de la crise libyenne, la résolution 1973 du Conseil de sécurité du 17 mars 2011 y fait expressément référence. Cet article vise à répondre à la question suivante : l’intervention militaire de l’ONU conduite par l’OTAN en Libye représente-t-elle un progrès ou un recul pour la responsabilité de protéger ?
L’euro contre l’Europe ?
Authors: Bourgeot Rémi 
Published: March 2016

Face à l’absence d’amélioration substantielle de la situation économique au sein d’une zone euro marquée par le chômage de masse, les responsables politiques semblent désemparés et s’en remettent de plus en plus à la Banque centrale européenne (BCE) pour assurer la préservation du système économique. Les débats se focalisent sur des questions institutionnelles, autour de la notion de « véritable union économique et monétaire », qui, bien qu’ayant une certaine légitimité, sont illusoires pour des raisons liées à l’équilibre politico-économique au sein de la zone euro, en particulier entre la France et l’Allemagne. Au-delà de la question de l’euro en tant que telle, l’économisme qui a conduit à la création de la monnaie unique apparaît comme le mode d’avènement d’un système administratif paradoxalement coupé des réalités économiques.
Réinterroger et reformuler le rapport aux personnes
Authors: Jaeger Marcel 
Published: March 2016

Parmi les questions traitées au cours des États généraux du travail social, celle des « usagers » a occupé une place centrale. Le mot lui-même a été très discuté. Mais au-delà des problèmes de vocabulaire, la refondation des rapports entre les professionnels de l’action sociale et les personnes accompagnées a été interrogée sous l’angle de la reconnaissance de leur citoyenneté. En effet, le respect des droits, à lui seul, ne suffit pas pour garantir une réelle solidarité et un travail social de qualité. Les débats auxquels cette thématique a donné lieu représentent un moment important pour l’évolution des pratiques d’accompagnement.
Le travail social au défi du développement social
Authors: Avenel Cyprien 
Published: March 2016

La notion de développement social est portée par la volonté de promouvoir la mise en œuvre de politiques émancipatrices, participatives. Dans le cadre de la décentralisation, elle traduit la volonté de s’appuyer sur l’atout de la proximité et incarne l’ambition d’une approche plus locale et partenariale des politiques publiques, afin de dépasser les approches verticales et sectorielles. Le développement social est une stratégie territoriale qui consiste à agir sur l’environnement dans tous ses aspects, à promouvoir le pouvoir d’agir individuel et collectif. En matière de gouvernance, il appartient aux institutions en responsabilité des politiques publiques de formaliser la coopération territoriale, le pilotage politique et institutionnel dans une conception de l’intervention, ascendante, transversale, qui se traduit par la coopération de tous les acteurs autour d’un projet social de territoire. Au niveau technique, le travail social doit être orienté vers des approches globales, des pratiques plus collectives. Les egts , à travers les assises interrégionales, ont été l’occasion de mettre en avant des « pratiques inspirantes », des initiatives et des projets collectifs dans les territoires. Dès lors, il s’agit d’étendre ces pratiques et pour cela de renforcer la formation des travailleurs sociaux à l’intervention collective, de favoriser une culture de la transversalité, le décloisonnement des secteurs d’activités comme des métiers.

Abstract
In 2013, the Thermo Scientific™ SureTect™ Listeria monocytogenes Real-Time PCR Assay was certified by the AOAC Research Institute (RI) Performance Tested MethodsSM program as a rapid method for the detection of L. monocytogenes from a wide range of food matrixes and surface samples. This report details the method modification studies undertaken to extend the analysis of this PCR assay to the Applied Biosystems™ 7500 Fast PCR Instrument and Applied Biosystems RapidFinder™ Express 2.0 software allowing the use of the SureTect assay on a 96 well format PCR cycler in addition to the current workflow, which uses the 24 well Thermo Scientific PikoReal™ PCR Instrument and Thermo Scientific SureTect software. Because this study was deemed by AOAC-RI to be a level 2 method modification study, a representative range of food matrixes covering raw ground turkey, 2% fat pasteurized milk, and bagged lettuce as well as stainless steel surface samples were analyzed with the Applied Biosystems 7500 Fast PCR Instrument and RapidFinder Express 2.0 software. All testing was conducted in comparison to the reference method detailed in International Organization for Standardization (ISO) 6579:2002. No significant difference by probability of detection statistical analysis was found between the SureTect Listeria monocytogenes PCR Assay or the ISO reference method methods for any of the matrixes analyzed during the study.

Published: March 2016

Pastagens formadas com Cynodonn lemfuensis Vanderyst são excelentes alternativas para alimentação dos rebanhos. A competição de plantas daninhas pode ocasionar prejuízos à pastagem, sendo que Vernonia polyanthes e Desmodium incanum estão entre as principais espécies competidoras. O objetivo do presente trabalho foi avaliar a eficácia de diferentes herbicidas no controle de Vernonia polyanthes e Desmodium incanum, aplicados em alto e baixo volume de calda. O experimento foi instalado em uma área formada há mais de 10 anos por grama-estrela-africana (Cynodonn lemfuensis). O delineamento experimental empregado foi o de blocos ao acaso, no esquema fatorial 2x7, sendo dois volumes de calda 50 e 200 L ha-1 e sete herbicidas. Foram avaliadas as variáveis fitotoxicidade na grama Cynodonn lemfuensisaos 3, 7, 14, 21 e 28 dias após a aplicação (DAA) e controle das plantas daninha Vernonia polyanthes e Desmodium incanum aos 7, 14, 21 e 28 DAA. Não foram encontrados níveis altos de fitotoxicidade na pastagem. Os tratamentos que proporcionaram os melhores controles de Vernonia polyanthes e Desmodium incanum foram fluroxypyr meptílico + triclopyr, 2,4 D + aminopiralide e 2,4 D + picloram. Os volumes de calda não proporcionaram diferenças significativas na avaliação de controle aos 28 DAA para herbicidas, porém foram superiores para alguns tratamentos aos 7, 14 e 21 DAA. Com isso o menor volume de calda (50 L ha-1) torna-se uma alternativa viável no controle dessas espécies na pastagem.
Potential and timescales for oxygen depletion in coastal upwelling systems: A box‐model analysis
Authors: Harrison C. S. , Hales B. , Siedlecki S. , Samelson R. M. 
Published: March 2016

AbstractA simple box model is used to examine oxygen depletion in an idealized ocean‐margin upwelling system. Near‐bottom oxygen depletion is controlled by a competition between flushing with oxygenated offshore source waters and respiration of particulate organic matter produced near the surface and retained near the bottom. Upwelling‐supplied nutrients are consumed in the surface box, and some surface particles sink to the bottom where they respire, consuming oxygen. Steady states characterize the potential for hypoxic near‐bottom oxygen depletion; this potential is greatest for faster sinking rates, and largely independent of production timescales except in that faster production allows faster sinking. Timescales for oxygen depletion depend on upwelling and productivity differently, however, as oxygen depletion can only be reached in meaningfully short times when productivity is rapid. Hypoxia thus requires fast production, to capture upwelled nutrients, and fast sinking, to deliver the respiration potential to model bottom waters. Combining timescales allows generalizations about tendencies toward hypoxia. If timescales of sinking are comparable to or smaller than the sum of those for respiration and flushing, the steady state will generally be hypoxic, and results indicate optimal timescales and conditions exist to generate hypoxia. For example, the timescale for approach to hypoxia lengthens with stronger upwelling, since surface particle and nutrient are shunted off‐shelf, in turn reducing subsurface respiration and oxygen depletion. This suggests that if upwelling winds intensify with climate change the increased forcing could offer mitigation of coastal hypoxia, even as the oxygen levels in upwelled source waters decline.
Trends of mean and extreme temperature indices since 1874 at low‐elevation sites in the southern Alps

Published: March 2016

AbstractWe describe the recovery of three daily meteorological records for the southern Alps (Domodossola, Riva del Garda, and Rovereto), all starting in the second half of the nineteenth century. We use these new data, along with additional records, to study regional changes in the mean temperature and extreme indices of heat waves and cold spells frequency and duration over the period 1874–2015. The records are homogenized using subdaily cloud cover observations as a constraint for the statistical model, an approach that has never been applied before in the literature. A case study based on a record of parallel observations between a traditional meteorological window and a modern screen shows that the use of cloud cover can reduce the root‐mean‐square error of the homogenization by up to 30% in comparison to an unaided statistical correction. We find that mean temperature in the southern Alps has increased by 1.4°C per century over the analyzed period, with larger increases in daily minimum temperatures than maximum temperatures. The number of hot days in summer has more than tripled, and a similar increase is observed in duration of heat waves. Cold days in winter have dropped at a similar rate. These trends are mainly caused by climate change over the last few decades.
Numerical investigation on the Ångström exponent of black carbon aerosol
Authors: Li Ji , Liu Chao , Yin Yan , Kumar K. Raghavendra 
Published: March 2016

AbstractBlack carbon (BC) plays an important role on the global and regional climate, whereas there are significant uncertainties on its optical properties. Among various optical properties, the Ångström exponent (AE) indicates the spectral variation of the particle‐optic interaction and is widely used to understand the aerosol properties. We consider the influence of BC geometry on its optical properties and assess the sensitivity of the AE to particle geometry and size distribution. The fractal aggregates with different fractal dimensions are used to represent realistic BC particles, and popular equivalent volume spherical and spheroidal models are also considered for comparison. Even if the fractal aggregates become highly compact and spherical, their optical properties are still significantly different from those of equivalent volume spheres or spheroids. Meanwhile, the Rayleigh‐Debye‐Gans approximation can hardly provide accurate results for all optical quantities of aggregates with different dimensions. The extinction Ångström exponent (EAE) and absorption Ångström exponent (AAE) are sensitive to both particle geometry and size distribution. With BC becoming more compact (from fractal aggregate to spheroid and to sphere), the AE becomes more sensitive to particle size distribution. The EAE and AAE of aggregates with different size distributions vary between 1.10–1.63 and 0.87–1.50, respectively, whereas those of the spheres or spheroids have wider ranges. Furthermore, the AE at smaller wavelengths (between 0.35 µm and 0.55 µm) is more sensitive to geometry and size distribution than that given by optical properties at larger wavelengths (between 0.55 µm and 0.88 µm).
