La standardisation du religieux. La norme halal et l’extension du champ de la normalisation
Authors: Bergeaud-Blackler Florence , Kokoszka Valérie 
Published: July 2017

Cet article décrit et analyse les enjeux et l’impact du travail normatif de la commission du Comité européen de normalisation « CEN 425/TC Halal food » sur la norme religieuse. Dans un premier temps, nous y interrogeons la façon dont la « machine » normative a pu étendre son intervention au domaine religieux et le trajet que le projet de norme a emprunté pour aboutir au CEN. Dans un second temps, nous analysons les principes de guidance du travail normatif et leur impact sur la production de la norme technique halal. Enfin, nous tentons de cerner les effets de la régulation économique transnationale sur l’État et sur les autorités religieuses et leur traduction sur les équilibres juridiques et politiques séculiers : soucieuse d’ouverture et de participation plurielle, la normalisation dictée par la « nouvelle approche » au moment du tournant néolibéral européen n’engendre-t-elle pas, in fine , un certain type de norme technico-religieuse que seuls les courants fondamentalistes seraient en mesure de soutenir ?
À la recherche de la signification perdue du paradoxe d’Allais
Authors: Jullien Dorian 
Published: July 2017

Dans « Le paradoxe d’Allais. Comment lui rendre sa signification perdue ? », Philippe Mongin [2014] propose une image contestable, parce qu’abusivement rassurante, de la rationalité des sujets participant aux expériences de MacCrimmon et Larsson [1979]. Nous montrons cela en restituant les données des auteurs pour l’effet de conséquence commune et l’effet de rapport commun (deux paradoxes d’Allais), que Mongin assimile, bien qu’il distingue ces deux effets. Deux tendances dans les données nous conduisent à rejoindre Mongin pour conclure que ces expériences sont une source d’inspiration fructueuse pour la théorie de la décision, ce que nous illustrons brièvement par le rôle qu’elles ont joué dans l’apparition de l’utilité espérée dépendante du rang et dans le tournant interindividuel en psychologie cognitive de la décision.
Stokes Flow of Viscous Fluid Past a Micropolar Fluid Spheroid
Authors: Prasad M. Krishna , Kaur Manpreet 
Published: July 2017

AbstractThe Stokes axisymmetric flow of an incompressible viscous fluid past a micropolar fluid spheroid whose shape deviates slightly from that of a sphere is studied analytically. The boundary conditions used are the vanishing of the normal velocities, the continuity of the tangential velocities, continuity of shear stresses and spin-vorticity relation at the surface of the spheroid. The hydrodynamic drag force acting on the fluid spheroid is calculated. An exact solution of the problem is obtained to the first order in the small parameter characterizing the deformation. It is observed that due to increase spin parameter value, the drag coefficient decreases. Well known results are deduced and comparisons are made with classical viscous fluid and micropolar fluid.
Pan-africanismo, negritude e teatro experimental do negro

Published: July 2017

http://dx.doi.org/10.5007/2175-8034.2016v18n1p109Pretende-se neste texto, que integra o conjunto de trabalhos em homenagem ao intelectual negro Guerreiro Ramos, analisar de modo sintético três temas interligados que fizeram parte do pensamento e da linha de ação em busca da libertação do negro. Trata-se do pan-africanismo, da Negritude e do Teatro Experimental do Negro brasileiro. O primeiro nasceu nos Estados Unidos e nas Antilhas Britânicas, em 1900; o segundo nasceu em Paris, no Quartier Latin por volta de 1935; e o terceiro, no Brasil, em 1944. Apesar de terem nascido em épocas e em espaços geográficos diferentes, os três movimentos convergem como discursos e atitudes intelectuais e políticos em defesa da libertação política do negro da diáspora e do continente africano; do reconhecimento de sua história, de sua cultura, de sua identidade; de sua plena humanidade e de uas contribuições na história da humanidade, assim como nos países das Américas, onde os negros foram deportados e escravizados. Guerreiro Ramos participou da construção do Teatro Experimental do Negro em companhia de Abdias de Nascimento, juntando suas vozes às dos intelectuais negros do Pan-africanismo e da negritude num movimento de ação em busca da inclusão do Negro no Brasil.

Formas de alocação de recursos no Brasil: elementos analíticos inescusáveis, segundo Guerreiro Ramos
Authors: Heidemann Francisco Grabiel 
Published: July 2017

http://dx.doi.org/10.5007/2175-8034.2016v18n1p187Nos anos de 1978, 1979 e 1981, o professor Alberto Guerreiro Ramos, que até então vivia exilado nos EUA, escreveu 24 artigos, publicados no Jornal do Brasil, do Rio, numa primeira iniciativa de reaproximação com a sociedade brasileira. A temática central dos artigos versou sobre as formas ou arranjos brasileiros de alocação de recursos, que se baseavam então exclusivamente no modelo de livre mercado (economia política)e, assim, ignoravam os elementos institucionais que marcaram as formas históricas de alocação vigentes em toda a história anterior à assim chamada revolução industrial. Nos artigos, Guerreiro Ramos resgatou elementos essenciais para a discussão sobre o tema da alocação, inclusive criticando a visão tacanha dos policy makers e governantes brasileiros atuantes, que acreditavam de forma pia e ingênua que o mercado era um modelo superior, exclusivo e único a orientar o governo em suas políticas de desenvolvimento do país. No presente texto,tangenciam-se os artigos de Ramos, para destacar os elementos analíticos que ele julgava ineludíveis e indispensáveis a um debate correto, profícuo e honesto sobre as formas alternativas de alocação de recursos e as relações de complementaridade entre elas numa sociedade como a brasileira, valendo-se sempre do mercado como sistema de referência.

Published: July 2017

http://dx.doi.org/10.5007/2175-8034.2016v18n1p83Guerreiro Ramos exerceu sua “sociologia militante” no Teatro Experimental do Negro. Desde jovem, ele vinha elaborando sua ideia do “sujeito pistêmico”. Seu legado teórico dialoga com o pensamento sociológico contemporâneo internacional. A autora propõe uma leitura de Guerreiro Ramos em diálogo com autores como Agnes Heller, W. E. B. Du Bois e Manuel Castells, enfocando paradigmas como redução sociológica, vida cotidiana, carecimentos radicais, identidades de resistência e de projeto. Neste artigo examina-se o papel de Guerreiro Ramos na idealização do Concurso Cristo de Cor, iniciativa do Teatro Experimental do Negro em 1955, realçando o TEN como exemplo do “sujeito epistêmico”. São apreciados textos de Guerreiro Ramos sobre a pintura de Abdias Nascimento, escritos durante o período de exílio dos dois nos EUA, concluindo que a abordagem da estética negra nesse período dá continuidade ao enfoque sobre esse tema desenvolvido nos trabalhos anteriores de Guerreiro Ramos no TEN.

Métodos: Estudo com dados de notificação de hepatite B na vigilância epidemiológica de município de Minas Gerais, entre 2007 a 2015, conduzido no Programa de Educação pelo Trabalho para a Saúde. Estatística descritiva e analítica, com nível de significância p<0,05. Resultados: Notificou-se 132 casos; dois óbitos. A idade dos notificados variou de zero a 87 anos, média de 35,8 (±14,0) anos. Maior freqüência para homens (52,3%) e baixa escolaridade (64,8%). A maioria não vacinou (81,8%) e teve resultado da sorologia HSBsAg positivo (90,1%); a imunização não se associou ao perfil sociodemográfico (p>0,05). Conclusão: Idade, escolaridade e sexo não foram associados à imunização, no esquema vacinal e no teste HSBsAg. A ausência de vacinação entre os notificados sugere necessidade de educação em saúde junto à população, orientando-na sobre possibilidade de proteção pela imunização.
Magnetospheric whistler mode ray tracing in a warm background plasma with finite electron and ion temperature
Authors: Maxworth A. S. , Gołkowski M. 
Published: July 2017

AbstractWhistler mode waves play a major role in the energy dynamics of the Earth's magnetosphere. Numerical ray tracing has been used for many years to determine the propagation trajectories of whistler mode waves from various sources, both natural and anthropogenic. Previous work has been under the ideal cold plasma assumption even though temperatures of the background ions and electrons are in the range of several eV. We perform numerical ray tracing with the inclusion of finite electron and ion temperatures to more accurately model the plasma environment of the Earth's magnetosphere. Finite temperature effects are found to play a significant role in the whistler mode refractive index surface only when the wave frequency is near the lower hybrid resonance frequency and the wave normal angle is oblique. In such cases, the primary effect on whistler mode propagation is to lower the refractive index magnitude and increase the group velocity with slight modifications to the ray trajectories. Landau damping is shown to increase slightly with the inclusion of finite temperature.
Origin of the ahead of tsunami traveling ionospheric disturbances during Sumatra tsunami and offshore forecasting

Published: July 2017

AbstractThe presence of ionospheric disturbances associated with Sumatra 2004 tsunami that propagated ahead of tsunami itself has previously been identified. However, their origin remains unresolved till date. Focusing on their origin mechanism, we document these ionospheric disturbances referred as Ahead of tsunami Traveling Ionospheric Disturbances (ATIDs). Using total electron content (TEC) data from GPS Aided GEO Augmented Navigation GPS receivers located near the Indian east coast, we first confirm the ATIDs presence in TEC that appear ~90 min ahead of the arrival of tsunami at the Indian east coast. We propose here a simulation study based on tsunami‐atmospheric‐ionospheric coupling that considers tsunamigenic acoustic gravity waves (AGWs) to excite these disturbances. We explain the ATIDs generation based on the dissipation of transverse mode of the primary AGWs. The simulation corroborates the excitation of ATIDs with characteristics similar to the observations. Therefore, we offer an alternative theoretical tool to monitor the offshore ATIDs where observations are either rare or not available and could be potentially important for the tsunami early warning.
Electron contribution in mirror instability in quasi‐linear regime
Authors: Noreen N. , Yoon P. H. , López R. A. , Zaheer S. 
Published: July 2017

AbstractThe solar wind is characterized by proton temperature anisotropies. The plasma compression generates the perpendicular anisotropy, T⊥>T∥, which may lead to the mirror mode instability for high beta situation. In the literature, the said unstable mode is largely discussed on the basis of linear theory or direct numerical simulations. In the present paper the mirror mode instability is discussed in the framework of simplified and reduced quasi‐linear kinetic theory, which includes the contribution of electrons. It is found that the linear growth rate associated with the electron mirror mode can be much higher than that associated with the proton mirror mode, and the electron mirror instability operates over a range of unstable wave numbers that is much broader than that for the proton mirror instability. However, upon carrying out the quasi‐linear analysis, it is shown that high initial growth rate does not necessarily imply dynamical importance, since the saturated magnetic field intensity associated with electron mirror instability is extremely low and that the influence on the particle temperatures is minimal. The present finding shows that under some circumstances, the dynamical consequences of a system cannot simply be estimated on the basis of the linear prediction alone and that nonlinear analysis must be taken into account. The electron mirror instability is a prime example of such a case.
Assessing variability in the size and strength of the North Atlantic subpolar gyre
Authors: Foukal Nicholas P. , Lozier M. Susan 
Published: July 2017

AbstractRecent studies on the size and strength of the North Atlantic subpolar gyre (SPG) offer contrasting assessments of the gyre's temporal variability: studies that use empirical orthogonal function (EOF) analyses of satellite sea‐surface height (SSH) report a rapid decline in SPG size and strength since 1992 (∼20% per decade), while concurrent in situ observations report either no trend or a slight decline. Here we investigate this discrepancy by analyzing the size and strength of the SPG with satellite SSH from 1993 to 2015 with two separate methods: indirectly via EOF analysis and more directly through measurements of the gyre center and boundary. We define the boundary of the gyre as the largest closed contour of SSH, the center as the minimum SSH, and the strength as the difference between the SSH at the boundary and the center. We identify a linear decline over the study period in the SPG strength (5.1% per decade), but find no statistically significant trend in the SPG area. The trend in the gyre strength is weaker than the EOF‐based trend and is most likely below the level of detection of the in situ measurements. We conclude that the variability previously identified as a sharp decline in SPG circulation can be more appropriately attributed to basin‐wide sea level rise during the satellite altimetry period. In addition, we find that the properties of the eastern SPG do not covary with the SPG size, suggesting that SPG dynamics do not control the strength of the intergyre throughput.
Time Asymmetric Quantum Mechanics and Shock Waves: Exploring the Irreversibility in Nonlinear Optics
Authors: Marcucci Giulia , Braidotti Maria Chiara , Gentilini Silvia , Conti Claudio 
Published: July 2017

AbstractThe description of irreversible phenomena is a still debated topic in quantum mechanics. Still nowadays, there is no clear procedure to distinguish the coupling with external baths from the intrinsic irreversibility in isolated systems. In 1928 Gamow introduced states with exponentially decaying observables not belonging to the conventional Hilbert space. These states are named Gamow vectors, and they belong to rigged Hilbert spaces. This review summarizes the contemporary approach using Gamow vectors and rigged Hilbert space formalism as foundations of a generalized “time asymmetric” quantum mechanics. We study the irreversible propagation of specific wave packets and show that the topic is surprisingly related to the problem of irreversibility of shock waves in classical nonlinear evolution. We specifically consider the applications in the field of nonlinear optics. We show that it is possible to emulate irreversible quantum mechanical process by the nonlinear evolution of a laser beam and we provide experimental tests by the generation of dispersive shock waves in highly nonlocal regimes. We demonstrate experimentally the quantization of decay rates predicted by the time‐asymmetric quantum mechanics. This work furnishes support to the idea of intrinsically irreversible wave propagation, and to novel tests of the foundations of quantum mechanics.
Unprecedented Nucleophilic Additions of Highly Polar Organometallic Compounds to Imines and Nitriles Using Water as a Non‐Innocent Reaction Medium
Authors: Dilauro Giuseppe , Dell'Aera Marzia , Vitale Paola , Capriati Vito , Perna Filippo Maria 
Published: July 2017

AbstractIn contrast to classic methods carried out under inert atmospheres with dry volatile organic solvents and often low temperatures, the addition of highly polar organometallic compounds to non‐activated imines and nitriles proceeds quickly, efficiently, and chemoselectively with a broad range of substrates at room temperature and under air with water as the only reaction medium. Secondary amines and tertiary carbinamines are furnished in yields of up to and over 99 %. The significant solvent D/H isotope effect observed for the on‐water nucleophilic additions of organolithium compounds to imines suggests that the on‐water catalysis arises from proton transfer across the organic–water interface. The strong intermolecular hydrogen bonds between water molecules may play a key role in disfavoring protonolysis, which occurs extensively in other protic media such as methanol. This work lays the foundation for reshaping many fundamental s‐block metal‐mediated organic transformations in water.
Ta(CNDipp)6: An Isocyanide Analogue of Hexacarbonyltantalum(0)
Authors: Chakarawet Khetpakorn , Davis‐Gilbert Zachary W. , Harstad Stephanie R. , Young Victor G. , Long Jeffrey R. , Ellis John E. 
Published: July 2017

AbstractHexakis(2,6‐diisopropylphenylisocyanide)tantalum is the first isocyanide analogue of the highly unstable Ta(CO)6 and represents the only well‐defined zerovalent tantalum complex to be prepared by conventional laboratory methods. Two prior examples of homoleptic Ta0 complexes are known, Ta(benzene)2 and Ta(dmpe)3, dmpe=1,2‐bis(dimethylphosphano)ethane, but these have only been accessed via ligand co‐condensation with tantalum vapor in a sophisticated metal‐atom reactor. Consistent with its 17‐electron nature, Ta(CNDipp)6 undergoes facile one‐electron oxidation, reduction, or disproportionation reactions. In this sense, it qualitatively resembles V(CO)6, the only paramagnetic homoleptic metal carbonyl isolable under ambient conditions.

AbstractThere is a relationship between patients with chronic kidney disease and coronary artery disease. These two entities share both common etiologies and risk factors. Management of different patients with coronary artery disease in the aspect of renal insufficiency and certain medications such as contrast media is thus of high importance. Treatment nihilism is a major problem though and healthcare providers must make efforts to maintain a stable kidney function in all coronary artery disease patients.Answer questions and earn CME: https://wileyhealthlearning.com/Activity2/5430077/Activity.aspx
Au‐Pd Bimetallic Nanoparticles Immobilised on Titanate Nanotubes: A Highly Active Catalyst for Selective Oxidation
Authors: Khawaji Motaz , Chadwick David 
Published: July 2017

AbstractIn this work, a highly active Au‐Pd/Ti‐NT catalyst has been produced by using colloidal synthesis and immobilisation on essentially sodium‐free Ti‐nanotubes (NTs). The new catalyst has markedly superior catalytic activity (turnover frequency>19 000 h−1) for the selective oxidation of benzyl alcohol compared with similar catalysts reported in the literature, and to Au‐Pd catalysts supported on Ti‐NTs prepared by adsorption, as well as conventional Au‐Pd/TiO2 prepared by impregnation. The superior catalytic activity of the catalyst is shown to be a result of the high metal dispersion on the external surfaces of Ti‐NTs, the narrow particle size distribution and the consistent formation of Au‐Pd mixed alloy nanoparticles in close to a 1:1 weight ratio. In repeated use, the Au‐Pd/Ti‐NT catalyst showed only a modest fall in activity, which is shown by FTIR to be associated mainly with the irreversible adsorption of benzoic acid and benzyl benzoate by the catalyst.
Electroreduction of Oxygen on PdPt Alloy Nanocubes in Alkaline and Acidic Media

Published: July 2017

AbstractThe electrochemical kinetic behavior of the oxygen reduction reaction (ORR) on PdPt alloy nanocubes of various compositions is investigated in 0.1 M KOH and 0.1 M HClO4 solutions, adopting the rotating disk electrode (RDE) configuration. The PdPt nanocubes are prepared in the presence of polyvinylpyrrolidone and identified by using transmission electron microscopy (TEM). TEM images reveal that the PdPt alloy nanoparticles have a preferential cubic shape and the average particle size is approximately 8–10 nm. CO‐stripping and cyclic voltammetry (CV) experiments are used for electrochemical cleaning and characterization of metal nanoparticles. The CV responses indicate alloy formation. In acidic media, Pd36Pt64 shows the highest specific activity (SA) for the ORR from the alloyed catalysts studied, but this activity is similar to that found with Pt and Pd nanocubes. However, in alkaline solution, the SA value for Pd72Pt28 is about two times higher than that of Pd and Pt nanocubes. The mechanistic pathway of O2 reduction on PdPt alloy nanocubes is analogous to that of pure Pd and Pt catalysts and the ORR proceeds via a 4‐electron pathway in both electrolyte solutions.
CuAAC in a Distal Pocket: Metal Active‐Template Synthesis of Strapped‐Porphyrin [2]Rotaxanes

Published: July 2017

AbstractThe synthesis of a porphyrin rotaxane by dipolar cycloaddition takes advantage of the ditopic character of a phenanthroline‐strapped porphyrin. The success of the click reaction was conditioned by the presence of both a coordinatively unsaturated metal in the porphyrin and a copper(I) bound to the phenanthroline, pointing at a new “tandem active metal template” mechanism.
