Rénovation de deux structures scolaires, au Danemark : Quelles évolutions, quelles perspectives pédagogiques ?
Authors: Roy France 
Published: February 2017

Cet article évoque le cas de deux écoles danoises « célèbres », chacune à sa manière, et qui ont bénéficié récemment de programmes ambitieux d’extension et de rénovation : il s’agit de Rødding Højskole (la Haute École Populaire de Rødding) et de Munkegaardsskolen (l’école de Munkegaard). Ces projets s’inscrivent dans l’histoire de ces écoles, de celle du pays, et se fondent sur une conception de l’enfant ou de l’homme développée de manière spécifique dans les pays nordiques. Ils témoignent d’une nécessaire adaptation des bâtiments aux évolutions et contraintes techniques, comme d’une amélioration, effective ou souhaitée, de l’éducation et des méthodes d’enseignement. Notre article rend compte, pour une part, de l’évolution architecturale de ces deux écoles, comprise chacune dans son contexte historique, social et éducatif, puis il établit une comparaison des deux projets ainsi que leurs fondements, ouvrant des perspectives de recherches relatives à l’apport pédagogique que ces évolutions architecturales pourraient induire.
Análisis y modelizado reológico de polímeros para su aplicación con tecnologías “auto-rizado” y su adaptación a las prácticas de Ingeniería de Materiales Poliméricos

Published: February 2017

<p>El procesado de los polímeros se realiza en estado fundido, por lo que es necesario realizar un análisis de las propiedades reológicas de estos materiales para poder evaluar su procesabilidad. Los modelos reológicos de los polímeros, como el modelo de Cross-WLF, posibilitan predecir la respuesta viscoelástica de un material y simular el comportamiento del mismo cuando va a ser procesado. En la elaboración mediante extrusión de fibras poliméricas bicomponente con efecto “self-crimping” (auto-rizado) es básico que los dos componentes presenten la misma viscosidad a la salida de la boquilla. Para ello, manteniendo el resto de condiciones de procesado de cada polímero idénticas, cada componente se debe extruir a una temperatura diferente. Gracias a la modelización reológica de Cross-WLF se pueden determinar las parejas de temperaturas dónde los materiales modelizados presentan la misma viscosidad. En el presente trabajo se plantea una sesión práctica para los alumnos de Ingeniería de Materiales Poliméricos. Con ayuda de un reómetro capilar los alumnos deberán ser capaces de determinar el comportamiento reológico de dos polímeros termoplásticos. Después ajustar dicho comportamiento al modelo de Cross-WLF y con ayuda de este modelo determinar las parejas de temperaturas dónde ambos polímeros estudiados presentan la misma viscosidad. </p>
Atando cabos entre contexto, competencias y modelización ¿Es posible enseñar ciencias a todas las personas?
Authors: Izquierdo Aymerich Mercè 
Published: February 2017

<p>La recomendación de enseñar ciencias en contexto, mediante modelos, para adquirir competencias se aplica a toda la enseñanza para conseguir la necesaria implicación del alumnado en lo que aprende. Pero nos damos cuenta de que la finalidad aprender ciencias en la etapa de enseñanza obligatoria (para que y por qué han de aprenderlas) es muy diferentes de la de la etapa no obligatoria, cuando los alumnos de ciencias han escogido esta materia entre otras. El proceso de construcción de conocimiento es un ejercicio de racionalidad si está de acuerdo con sus finalidades. Por ello, si de verdad se quiere conseguir enseñar ciencias a todos, se ha de diseñar el currículo del ciclo básico, obligatorio, con mayor libertad frente al no obligatorio, sin convertirlo en una copia light del currículo especializado. Y la evaluación final de los conocimientos adquiridos en la enseñanza básica han de estar de acuerdo con las competencias curriculares que se han de haber adquirido, que también son diferentes. En esta conferencia se va a hacer una propuesta de diseño de currículo competencial para la enseñanza de una ‘ciencia para todos’ que pretende desarrollar actividad científica escolar que modelice un contexto relevante y en la que confluyen las diferentes disciplinas científicas</p>

Sublingual Epidermoid Cyst: A Rare Presentation
Authors: Jain Leena , Maurya Ashish K , Jadia Shalini , Qureshi Sadat 
Published: February 2017

ABSTRACT
Infection of pilo-sebacious gland or traumatic migration of epidermis to the deeper layers of the skin can lead to epidermoid cyst. Any site of the body which is lined by squamous epithelium can be the site of epidermoid cyst. We present a case of sublingual epidermoid cyst in a 14-year-old female, who presented with a slow-growing, soft, midline swelling in submental region. Cyst was excised under local anesthesia with sedation. Histopathological examination revealed a cystic wall lined by keratinizing squamous epithelium with lamellated keratin and fibrocollagenous tissue with congested blood vessels, along with subcutaneous fat and muscle bundles, which is suggestive of epidermoid cyst.

Antarctic subglacial lakes drain through sediment-floored canals: theory and model testing on real and idealized domains
Authors: Carter Sasha P. , Fricker Helen A. , Siegfried Matthew R. 
Published: February 2017

Abstract. Over the past decade, satellite observations of ice surface height have revealed that active subglacial lake systems are widespread under the Antarctic Ice Sheet, including the ice streams. For some of these systems, additional observations of ice-stream motion have shown that lake activity can affect ice-stream dynamics. Despite all this new information, we still have insufficient understanding of the lake-drainage process to incorporate it into ice-sheet models. Process models for drainage of ice-dammed lakes based on conventional R-channels incised into the base of the ice through melting are unable to reproduce the timing and magnitude of drainage from Antarctic subglacial lakes estimated from satellite altimetry given the low hydraulic gradients along which such lakes drain. We have developed an alternative process model, in which channels are mechanically eroded into the underlying deformable subglacial sediment. When applied to the known active lakes of the Whillans–Mercer ice-stream system, the model successfully reproduced both the inferred magnitudes and recurrence intervals of lake-volume changes, derived from Ice, Cloud and land Elevation Satellite (ICESat) laser altimeter data for the period 2003–2009. Water pressures in our model changed as the flood evolved: during drainage, water pressures initially increased as water flowed out of the lake primarily via a distributed system, then decreased as the channelized system grew, establishing a pressure gradient that drew water away from the distributed system. This evolution of the drainage system can result in the observed internal variability of ice flow over time. If we are correct that active subglacial lakes drain through canals in the sediment, this mechanism also implies that active lakes are typically located in regions underlain by thick subglacial sediment, which may explain why they are not readily observed using radio-echo-sounding techniques.
L’essayiste « fictif »
Authors: Chabot Julien-Bernard 
Published: February 2017

Avec Le romancier fictif, André Belleau a élaboré un cadre de pensée qui aide à mieux comprendre les modalités par lesquelles la littérature, en contexte québécois, met en scène la figure de l’écrivain. La réflexion que propose cet article part des pistes d’interprétation fournies par Belleau afin d’étudier les quelques essais de Surprendre les voix où l’essayiste s’est lui-même donné en autoreprésentation. Plutôt que de succomber à la dissociation qu’impose fréquemment aux écrivains fictifs le « conflit des codes » caractéristique de l’institution littéraire québécoise, le Belleau des essais mimétiques parvient à concilier la double exigence du savant et du populaire. Il en résulte un être hybride, proprement silénique, qui puise dans la tradition carnavalesque un mode de représentation servant à faire contrepoids aux hauteurs où loge la pensée essayistique.

AbstractStammzellen kommen immer wieder in die Nachrichten, etwa als Wundermittel für eine zukünftige Ersatzteilmedizin, aber auch als Angriffsziel für neuartige Krebstherapien. Viel zu unscharf ist allerdings noch das Verständnis des eigentlichen Wesens der Stammzellen: Ist ihre wundersame Totipotenz oder Pluripotenz eine intrinsische Eigenschaft oder wird sie auch von der Umwelt, der so genannten Stammzellnische geprägt?

Transplant with a twist: A pitfall in sonographic diagnosis of renal transplant torsion
Authors: Narasimhan Evan , Kennedy Anne , Campsen Jeffrey 
Published: February 2017

ABSTRACTTorsion is an uncommon cause of impaired function in a renal transplant. We present a case of intraperitoneal transplant torsion secondary to adhesions to the left fallopian tube and ovary. Inability to confirm renal venous flow with Doppler misled to the erroneous sonographic diagnosis of renal vein thrombosis, although end diastolic flow was absent rather than reversed. The correct diagnosis was made with CT. The combination of abnormal orientation of the graft on ultrasonography, acutely impaired renal function, and abnormal Doppler study should have led to a diagnosis of transplant torsion. The case is also unusual in that the lead point was adnexal pathology. © 2017 Wiley Periodicals, Inc. J Clin Ultrasound 45:528–530, 2017
Monitoring a PGD solver for parametric power flow problems with goal‐oriented error assessment
Authors: García‐Blanco R. , Borzacchiello D. , Chinesta F. , Diez P. 
Published: February 2017

SummaryThe parametric analysis of electric grids requires carrying out a large number of power flow computations. The different parameters describe loading conditions and grid properties. In this framework, the proper generalized decomposition (PGD) provides a numerical solution explicitly accounting for the parametric dependence. Once the PGD solution is available, exploring the multidimensional parametric space is computationally inexpensive. The aim of this paper is to provide tools to monitor the error associated with this significant computational gain and to guarantee the quality of the PGD solution. In this case, the PGD algorithm consists in three nested loops that correspond to (1) iterating algebraic solver, (2) number of terms in the separable greedy expansion, and (3) the alternated directions for each term. In the proposed approach, the three loops are controlled by stopping criteria based on residual goal‐oriented error estimates. This allows one for using only the computational resources necessary to achieve the accuracy prescribed by the end‐user. The paper discusses how to compute the goal‐oriented error estimates. This requires linearizing the error equation and the quantity of interest to derive an efficient error representation based on an adjoint problem. The efficiency of the proposed approach is demonstrated on benchmark problems. Copyright © 2016 John Wiley & Sons, Ltd.
Excitation energy dependence of initial phase shift in Kerr rotation of resident electron spin polarization in a CdTe single quantum well

Published: February 2017

AbstractThe generation dynamics of a resident electron spin polarization involve the formation and transformation of the associated optically excited states depending on the excitation photon energy. Initial phase shift in the precession of a resident electron spin polarization gives the important clues to reveal the interplay between the associated excited states and resident electrons. In this work, the excitation energy dependence of the initial phase shift in Kerr rotation of a resident electron spin polarization is investigated in a CdTe/CdMgTe single quantum well under a low magnetic field. Through the careful analysis of the spin precession, the excited electron–heavy‐hole pairs show unique spin dynamics when the excitation energy is increasing past the neutral exciton resonance. Meanwhile, the negative initial phase shift becomes significantly large in magnitude. The larger initial phase shift and the unique precession traces are caused by the transformation from neutral excitons to negative trions with accompanying the hole spin‐flip. The exciton‐to‐trion transformation time is estimated experimentally to be 160 ps.
Growth and characterization of (Zn,Sn,Ga)As2 thin films grown on GaAs(001) substrate by molecular beam epitaxy
Authors: Toyota H. , Terauchi T. , Hidaka S. , Kato T. , Uchitomi N. 
Published: February 2017

AbstractGa‐incorporated ZnSnAs thin films were grown on semi‐insulating GaAs(001) substrate by molecular beam epitaxy, and the structural, compositional, and electrical properties were characterized with respect to achieving conduction‐type control. Compositional analysis with an electron‐probe micro analyzer indicated that Ga atoms are substituted for cation (Zn and Sn) atoms and that the Ga/Sn beam equivalent pressure ratio has only a small influence on the Ga concentration. In addition, the composition ratios of Zn to all the cation sites were 2.0–5.7% smaller than that of Sn. ‐scan X‐ray diffraction analyses confirmed the epitaxial growth of (Zn,Sn,Ga)As thin films on GaAs(001) substrates. Reciprocal space maps revealed that these thin films are almost fully relaxed, and the lattice constants are in good agreement with Vegard's law. Hall effect measurements of all the (Zn,Sn,Ga)As thin films indicated n‐type conductivity, which was due to the high Ga content of 44.1–47.8% on the cation sites.

Abstract

Background
Operative mortality and morbidity rates after hepato-biliary-pancreatic (BILI) surgery remain high. This study evaluated clinical characteristics and surgical outcomes of patients who underwent BILI surgery and investigated predictors of outcomes by focusing on sarcopenia.

Materials and methods
A prospective observational study was performed for consecutive patients who underwent BILI surgery at our institution between June 2013 and May 2014. Sarcopenia was evaluated using computed tomography. Surgical outcomes and the influence of sarcopenia on outcomes were evaluated. Subsequently, the impact of prognostic factors, including sarcopenia, associated with postoperative infections was assessed using multivariate analyses.

Results
Total mortality, major complications, and infectious disease rates for all 157 patients were 0%, 9.6%, and 21.7%, respectively. Thirty-eight patients met the criteria for sarcopenia. The sarcopenic group had a significantly higher incidence of infectious complications compared to the non-sarcopenic group (36.8% vs. 17.2%; P = 0.015). During multivariate analyses of prognostic factors, sarcopenia (hazard ratio = 2.44; P = 0.043) and diabetes mellitus (hazard ratio = 3.07; P = 0.01) were detected as independent predictors of postoperative infections.

Conclusions
Sarcopenia is an independent preoperative predictor of infection after BILI surgery. Earlier diagnosis and therapeutic intervention for patients with sarcopenia could be useful in the development of comprehensive approaches for perioperative care.

Highlights
Seasonal control of Petermann Gletscher ice-shelf melt by the ocean's response to sea-ice cover in Nares Strait

Published: February 2017

AbstractPetermann Gletscher drains ~4% of the Greenland ice sheet (GrIS) area, with ~80% of its mass loss occurring by basal melting of its ice shelf. We use a high-resolution coupled ocean and sea-ice model with a thermodynamic glacial ice shelf to diagnose ocean-controlled seasonality in basal melting of the Petermann ice shelf. Basal melt rates increase by ~20% in summer due to a seasonal shift in ocean circulation within Nares Strait that is associated with the transition from landfast sea ice to mobile sea ice. Under landfast ice, cold near-surface waters are maintained on the eastern side of the strait and within Petermann Fjord, reducing basal melt and insulating the ice shelf. Under mobile sea ice, warm waters are upwelled on the eastern side of the strait and, mediated by local instabilities and eddies, enter Petermann Fjord, enhancing basal melt down to depths of 200 m. The transition between these states occurs rapidly, and seasonal changes within Nares Strait are conveyed into the fjord within the same season. These results suggest that long-term changes in the length of the landfast sea-ice season will substantially alter the structure of Petermann ice shelf and its contribution to GrIS mass loss.

AbstractConstitutive NF-E2-related factor 2 (Nrf2, NFE2L2) activation has been recently reported to play a pivotal role in enhancing cell survival and resistance to anticancer drugs in many tumors. Wogonin had strong reversal potency via reduction of Nrf2 mRNA in Adriamycin (ADR)-induced resistant human chronic myelogenous leukemia (CML) K562/A02, but the mechanism of reduction of Nrf2 mRNA was still unclear. In this study, we aimed to delineate the mechanism by which Wogonin suppressed transcription of Nrf2 in resistant CML cells and further evaluate the reversal effects of Wogonin on the established animal models. Data indicated that Wogonin suppressed transcription of Nrf2 by NF-κB inactivation. Wogonin inhibited the binding of p65 to Nrf2 by suppression of the κB-binding activity. Further research revealed the κB2 site was responsible for the decreased Nrf2 by Wogonin in resistant K562 cells. Furthermore, reduction of pY705-Stat3 was involved in inhibition of the binding of p65 to Nrf2 by Wogonin. In vivo, Wogonin potentiated the inhibitory effect of ADR on leukemia development by suppressing pY705-Stat3 and Nrf2 signaling. In summary, these results demonstrated Wogonin could combat chemoresistance effectively through inhibiting Nrf2 via Stat3/NF-κB signaling, and supported that Wogonin can be developed into an efficient natural sensitizer for resistant human myelogenous leukemia.
Dynamics on networks: competition of temporal and topological correlations
Authors: Artime Oriol , Ramasco José J. , San Miguel Maxi 
Published: February 2017

AbstractLinks in many real-world networks activate and deactivate in correspondence to the sporadic interactions between the elements of the system. The activation patterns may be irregular or bursty and play an important role on the dynamics of processes taking place in the network. Information or disease spreading in networks are paradigmatic examples of this situation. Besides burstiness, several correlations may appear in the process of link activation: memory effects imply temporal correlations, but also the existence of communities in the network may mediate the activation patterns of internal an external links. Here we study the competition of topological and temporal correlations in link activation and how they affect the dynamics of systems running on the network. Interestingly, both types of correlations by separate have opposite effects: one (topological) delays the dynamics of processes on the network, while the other (temporal) accelerates it. When they occur together, our results show that the direction and intensity of the final outcome depends on the competition in a non trivial way.
