Du maternage des mères à la reconnaissance du bébé
Authors: Israël Jacky 
Published: June 2015

Peu de mamans se sentent « suffisamment bonnes » et beaucoup sont prisonnières de la transparence psychique. Bien des pères sont de véritables bouées de sauvetage. Le pédiatre peut amortir les débordements psychiques par ses capacités d’accueil. Les parents ressentent d’emblée s’ils sont bien accueillis, et surtout entendus. Le fait d’expliquer le mode de fonctionnement du bébé dédramatise et rassure. Reconnaître les difficultés rencontrées par les parents ouvre un véritable dialogue. Enfin, les compétences du bébé et sa manière de « danser » après sa mise en relation avec le pédiatre, suffisent à détendre ses parents, avant un examen médical rigoureux qui permettra la plupart du temps d’éliminer une réelle souffrance, voire une maladie.
Il y a de nombreux parents dans les albums…
Authors: Rateau Dominique 
Published: June 2015

Il est urgent de lire ! Il est urgent de lire des livres avec des images ! Il est urgent de lire ensemble des albums — œuvres littéraires et artistiques — qui interrogent et permettent à chacun de cheminer vers une pensée personnelle et indépendante. Il est urgent de proposer aux enfants, dès le plus jeune âge, mais aussi aux adultes qui les accompagnent, des lectures qui permettent à chacun de cultiver ses questions, ses doutes, ses croyances et de les exprimer… Il est urgent et primordial de « penser » et d’interroger constamment nos connaissances, nos théories, nos cadres de références, nos croyances… Il y a de nombreux parents et de nombreux enfants dans les livres avec des mots et des images publiés par les éditeurs jeunesse. Les histoires de familles y sont omniprésentes, mettant en scène toutes sortes de mères, de pères, toutes sortes de masculin, de féminin, toutes sortes d’hommes, de femmes, toutes sortes de parents… Mais tous les albums ne se valent pas. Nombreux sont ceux qui proposent des modèles. Devenus des manuels de bonne ou d’anti-conduite, ils envahissent le marché. Ils font consensus, et pourtant ils ne servent ni la littérature, ni la lecture, ni les lecteurs, ni les enfants, ni les parents, ni la réflexion, ni la société. D’autres font œuvres. Ils développent nos imaginaires, éveillent nos désirs, donnent à rêver et à penser. Il est urgent d’agir en lisant de la littérature. Il est urgent de transmettre partout et en tous lieux la nécessité de lire, de réfléchir, de penser.
Monotone Classes of Dendrites
Authors: Martínez-de-la-Vega Veronica , Mouron Christopher 
Published: June 2015

AbstractContinua X and Y are monotone equivalent if there exist monotone onto maps f : X→ Y and g: Y →X. A continuum X is isolated with respect to monotone maps if every continuumthat is monotone equivalent to X must also be homeomorphic to X. In this paper we show that a dendrite X is isolated with respect to monotone maps if and only if the set of ramification points of X is finite. In this way we fully characterize the classes of dendrites that are monotone isolated.
Lattice Boltzmann Simulations of Thermocapillary Motion of Droplets in Microfluidic Channels
Authors: Li Jonathan , Liu Haihu , Ioannou Nikolaos , Zhang Yonghao , Reese Jason M. 
Published: June 2015

AbstractOur recently developed lattice Boltzmann model is used to simulate droplet dynamical behaviour governed by thermocapillary force in microchannels. One key research challenge for developing droplet-based microfluidic systems is control of droplet motion and its dynamic behaviour. We numerically demonstrate that the thermocapillary force can be exploited for microdroplet manipulations including synchronisation, sorting, and splitting. This work indicates that the lattice Boltzmann method provides a promising design simulation tool for developing complex droplet-based microfluidic devices.
Heavy Metals (Cd, Pb, Cu, Fe, Cr, Mn, Zn) Contents in Ungulates of Ogun State Agricultural Farm Settlement, Ago - Iwoye, Nigeria

Published: June 2015

Heavy metals are natural components of the earth's crust which can neither be degraded nor destroyed and were known as trace elements as they occur in minute concentrations in biological systems. This study was aimed to investigate the bioaccumulation of heavy metals in the commonly consumed duikers in an agricultural farm settlement. Commercially available four duikers (Cephalophus spp.) were collected for four weeks and four organs (skin, lungs, kidney and liver) from each sample were used. All the organs sampled were subjected to 7 heavy metals (Fe, Cu, Pb, Zn, Mn, Cr and Cd) tests using Atomic Absorption Spectrophotometer (VGB 210 System) following standard procedure. All data were subjected to statistical analysis to find out the significant difference of heavy metal in each organ of and their accumulation effects. Heavy metals concentration in Cephalophus spp was in descending order of Cd (0.29±0.02 - 0.92±0.01) < Pb (0.52±0.03-1.08±0.06) < Cr (0.78±0.05-2.47±0.19) < Cu (5.05±0.30-13.35±0.54) < Mn (7.30±0.49-14.20±1.06) < Zn (75.52±3.04-125.28±10.57) < Fe (381.52±14.25-761.40±5.76). They accumulated the metals in ascending order Fe > Zn > Mn > Cu > Cd > Cr > Pb for skin, Fe > Zn > Mn > Cu > Cr > Cd > Pb for liver, Fe > Zn > Mn > Cu > Cr > Pb > Cd for lung and Fe > Zn > Cu > Mn > Cr > Pb > Cd for kidney. Variability of heavy metals in Cephalophus species may not be due to the differences in the animal diet and habitat, but, the level of acute or chronic contamination of their diet and habitat.

Avaliação da eficácia da “política mandatória” em repositórios: um estudo de caso no Instituto Politécnico de Castelo Branco – Portugal
Authors: Rodrigues Maria Eduarda Pereira , Rodrigues António Moitinho 
Published: June 2015

Introdução: Apresentam-se os resultados de um estudo sobre o efeito da aprovação e implantação da Política de Depósito de Documentos (PDD) no Repositório Científico do Instituto Politécnico de Castelo Branco - Portugal (RCIPCB). Método: O trabalho foi dividido em duas partes. A primeira parte diz respeito à posição dos docentes/investigadores sobre a PDD e sobre o arquivamento dos seus documentos científicos no Repositório; a segunda parte diz respeito ao desempenho do RCIPCB enquanto tal. O estudo foi realizado mediante a aplicação de um inquérito distribuído online aos docentes/investigadores do IPCB (n=505), sujeito a uma análise estatística descritiva. Resultados: 96,6% dos docentes/investigadores informaram conhecer o RCIPCB; 66,0% dos inquiridos respondeu conhecer a PDD; apenas 11,9% dos respondentes indicaram ter depositado de quatro a mais documentos da sua produção científica de 2011 no Repositório; e, 50,8% dos docentes/investigadores referiram não terem depositado qualquer documento relativo a 2011. As razões mais invocadas para este comportamento foram: a falta de tempo (43,5%); questões relacionadas com direitos de autor (21,7%); e o esquecimento (17,4%). Após a aprovação da PDD houve uma redução no número total de documentos depositados (10,3%) e do número de documentos autoarquivados (44,0%). Conclusões: Conclui-se que a PDD não produziu os resultados desejados nem ao nível do autoarquivo, nem ao nível do crescimento do Repositório pela via do arquivo mediado. Considera-se ser necessária a adoção de medidas complementares de fomento do arquivo e do autoarquivo no RCIPCB.
« Le narrateur se lève » : narration indécidable et fondation illégitime dans Les particules élémentaires de Michel Houellebecq
Authors: Thériault Patrick 
Published: June 2015

Le lecteur des Particules élémentaires ne peut qu’être déconcerté par l’apparition, vers la fin du roman et dans le cadre même de la représentation, d’un personnage identifié (au) « narrateur » : « Le narrateur se lève ». En faisant « se lever » ce narrateur-personnage, le texte de Michel Houellebecq soulève une question d’ordre référentiel qu’on ne peut, en toute rigueur, ignorer : qui (quelle instance, quelle voix, quelle figure), en venant comme le dédoubler, s’énonce ainsi à la place du narrateur-personnage ? Le roman n’offre aucune réponse certaine à cette question ; il engramme en cela une forme d’énigme narratologique qu’on peut qualifier d’indécidable. Pour autant, cette énigme n’en est pas moins un index critique et un levier heuristique de première importance, à travers lesquels, comme j’en ferai l’hypothèse, il est possible d’entrapercevoir la richesse épistémologique des Particules élémentaires. De manière plus précise, je m’attacherai à montrer comment, en posant la question du métalangage et en confinant en dernière analyse à ce que Jean-François Lyotard appelle l’« aporie logique de l’autorisation », cette énigme narratologique fait dialoguer le roman de Houellebecq avec le discours philosophique sur la postmodernité et la fin de l’Histoire.
How sensitive are aerosol‐precipitation interactions to the warm rain representation?
Authors: Hill A. A. , Shipway B. J. , Boutle I. A. 
Published: June 2015

AbstractIt is widely acknowledged that aerosol‐cloud interactions are a major uncertainty in climate and numerical weather prediction. One of the sources of uncertainty is the sensitivity of the cloud microphysics parameterization to changes in aerosol, in particular the response of precipitation. In this work, we conduct an idealized, dynamically consistent, intercomparison of warm rain microphysics schemes to understand this source of uncertainty. The aims of this investigation are: (i) investigate how sensitive precipitation susceptibility (S0) is to cloud microphysics representation and (ii) use S0 to determine the minimum complexity of microphysics required to produce a consistent precipitation response to changes in cloud drop number concentration (Nd). The main results from this work are: (i) over a large range of liquid water path and Nd, all the bulk schemes, but particularly the single moment schemes, artificially produce rain too rapidly. Relative to a reference bin microphysics scheme, this leads to a low in‐cloud S0 and impacts the evolution of S0 over time. (ii) Rain evaporation causes surface S0 from all schemes to be larger than the cloud base S0. The magnitude of the change in S0 with altitude is dependent on the scheme and the representation of the rain drop size distribution. Overall, we show that single‐moment schemes produce the largest range in the sensitivity of precipitation to changes in Nd. Modifying rain production parameterization alone does not reduce this spread. Instead, increasing the complexity of the rain representation to double‐moment significantly improves this behavior and the overall consistency between schemes.
Biogeochemical drivers of the fate of riverine mercury discharged to the global and Arctic oceans

Published: June 2015

AbstractRivers discharge 28 ± 13 Mmol yr−1 of mercury (Hg) to ocean margins, an amount comparable to atmospheric deposition to the global oceans. Most of the Hg discharged by rivers is sequestered by burial of benthic sediment in estuaries or the coastal zone, but some is evaded to the atmosphere and some is exported to the open ocean. We investigate the fate of riverine Hg by developing a new global 3‐D simulation for Hg in the Massachusetts Institute of Technology ocean general circulation model. The model includes plankton dynamics and carbon respiration (DARWIN project model) coupled to inorganic Hg chemistry. Results are consistent with observed spatial patterns and magnitudes of surface ocean Hg concentrations. We use observational constraints on seawater Hg concentrations and evasion to infer that most Hg from rivers is sorbed to refractory organic carbon and preferentially buried. Only 6% of Hg discharged by rivers (1.8 Mmol yr−1) is transported to the open ocean on a global basis. This fraction varies from a low of 2.6% in East Asia due to the barrier imposed by the Korean Peninsula and Japanese archipelago, up to 25% in eastern North America facilitated by the Gulf Stream. In the Arctic Ocean, low tributary particle loads and efficient degradation of particulate organic carbon by deltaic microbial communities favor a more labile riverine Hg pool. Evasion of Hg to the Arctic atmosphere is indirectly enhanced by heat transport during spring freshet that accelerates sea ice melt and ice rafting. Discharges of 0.23 Mmol Hg yr−1 from Arctic rivers can explain the observed summer maximum in the Arctic atmosphere, and this magnitude of releases is consistent with recent observations. Our work indicates that rivers are major contributors to Hg loads in the Arctic Ocean.
Magmatic water contents determined through clinopyroxene: Examples from the Western Canary Islands, Spain

Published: June 2015

AbstractWater is a key parameter in magma genesis, magma evolution, and resulting eruption styles, because it controls the density, the viscosity, as well as the melting and crystallization behavior of a melt. The parental water content of a magma is usually measured through melt inclusions in minerals such as olivine, a method which may be hampered, however, by the lack of melt inclusions suitable for analysis, or postentrapment changes in their water content. An alternative way to reconstruct the water content of a magma is to use nominally anhydrous minerals (NAMs), such as pyroxene, which take up low concentrations of hydrogen as a function of the magma's water content. During magma degassing and eruption, however, NAMs may dehydrate. We therefore tested a method to reconstruct the water contents of dehydrated clinopyroxene phenocrysts from the Western Canary islands (n = 28) through rehydration experiments followed by infrared and Mössbauer spectroscopy. Employing currently available crystal/melt partitioning data, the results of the experiments were used to calculate parental water contents of 0.71 ± 0.07 to 1.49 ± 0.15 wt % H2O for Western Canary magmas during clinopyroxene crystallization at upper mantle conditions. This H2O range is in agreement with calculated water contents using plagioclase‐liquid‐hygrometry, and with previously published data for mafic lavas from the Canary Islands and comparable ocean island systems elsewhere. Utilizing NAMs in combination with hydrogen treatment can therefore serve as a proxy for pre‐eruptive H2O contents, which we anticipate becoming a useful method applicable to mafic rocks where pyroxene is the main phenocryst phase.
Shorter intervals between great earthquakes near Sendai: Scour ponds and a sand layer attributable to A.D. 1454 overwash

Published: June 2015

AbstractA sparsely documented tsunami in 1454 may subdivide the recurrence interval between the 869 and 2011 tsunamis near Sendai, as judged from geomorphic, stratigraphic, and archival evidence. Pond‐filled breaches cut across beach ridges on century‐old topographic maps. The basal pond deposit in one of these breaches postdates 1454. Stratigraphy on Sendai Plain includes a sand sheet that contains marine and brackish diatoms. Radiocarbon ages suggest that the sheet dates to 1406–1615 (2σ), and written records for this interval in Tohoku mention a tsunami in 1454. The inferred inundation extended 1.0–2.5 km inland from an approximate medieval shoreline. Simulated tsunamis that best account for the sand sheet require a thrust earthquake of moment magnitude 8.4 or larger. If the sand sheet represents the 1454 tsunami, the two most recent intervals between great thrust earthquakes in Sendai region spanned 585 and 557 years.
Acoustic source inversion to estimate volume flux from volcanic explosions
Authors: Kim Keehoon , Fee David , Yokoo Akihiko , Lees Jonathan M. 
Published: June 2015

AbstractWe present an acoustic waveform inversion technique for infrasound data to estimate volume fluxes from volcanic eruptions. Previous inversion techniques have been limited by the use of a 1‐D Green's function in a free space or half space, which depends only on the source‐receiver distance and neglects volcanic topography. Our method exploits full 3‐D Green's functions computed by a numerical method that takes into account realistic topographic scattering. We apply this method to vulcanian eruptions at Sakurajima Volcano, Japan. Our inversion results produce excellent waveform fits to field observations and demonstrate that full 3‐D Green's functions are necessary for accurate volume flux inversion. Conventional inversions without consideration of topographic propagation effects may lead to large errors in the source parameter estimate. The presented inversion technique will substantially improve the accuracy of eruption source parameter estimation (cf. mass eruption rate) during volcanic eruptions and provide critical constraints for volcanic eruption dynamics and ash dispersal forecasting for aviation safety. Application of this approach to chemical and nuclear explosions will also provide valuable source information (e.g., the amount of energy released) previously unavailable.
Roles of wind shear at different vertical levels: Cloud system organization and properties

Published: June 2015

AbstractUnderstanding critical processes that contribute to the organization of mesoscale convective systems (MCSs) is important for accurate weather forecasts and climate predictions. In this study, we investigate the effects of wind shear at different vertical levels on the organization and properties of convective systems using the Weather Research and Forecasting model with spectral bin microphysics. Based on a control run for a MCS with weak wind shear (Ctrl), we find that increasing wind shear at the lower troposphere (L‐shear) leads to a more organized quasi‐line convective system. Strong wind shear in the middle troposphere (M‐shear) tends to produce large vorticity and form a mesocyclone circulation and an isolated strong storm that leans toward supercellular structure. By increasing wind shear at the upper vertical levels only (U‐shear), the organization of the convection is not changed much, but the convective intensity is weakened. Increasing wind shear in the middle troposphere for the selected case results in a significant drying, and the drying is more significant when conserving moisture advection at the lateral boundaries, contributing to the suppressed convective strength and precipitation relative to Ctrl. Precipitation in the L‐shear and U‐shear does not change much from Ctrl. Evident changes of cloud macrophysical and microphysical properties in the strong wind shear cases are mainly due to large changes in convective organization and water vapor. The insights obtained from this study help us better understand the major factors contributing to convective organization and precipitation.
The role of blocking in the summer 2014 collapse of Etesians over the eastern Mediterranean

Published: June 2015

AbstractWe investigate the dynamical harbingers leading to the remarkable summer 2014 decline of the northerly flow (Etesians) over the eastern Mediterranean. From mid‐July to mid‐August four distinct episodes of unseasonal southerly flow were identified and associated with upper level troughs over central Europe and the Balkans. These features developed as repeated episodes of wave breaking, leading to blocking over Europe in July, and triggered equatorward streamers of high potential vorticity. During July a twofold increase in blocking occurrence against climatology was identified over parts of Europe and was part of a five‐wave hemispheric pattern featuring abundant high‐latitude blocking also over central Asia, the central Pacific, and western Atlantic. Overall, the frequent European blocking resulted in the southward displacement of the midlatitude storm track toward the Balkans and the relaxation of the traditional sharp east‐west pressure gradient that triggered the collapse of Etesians. The bifurcation of the midlatitude jet caused by blocking led to the intensification of the westerly flow over the Mediterranean, accompanying the passing disturbances farther to the north, which combined with the weak Etesians resulting in a dramatic modification of the large‐scale circulation over the Mediterranean Basin.
