Trois révolutions géographiques de la grande vitesse ferroviaire en France. (Three geographical revolutions of high-speed rail in France)
Authors: Varlet Jean
Published: December 2014

Des recherches menées depuis un quart de siècle sur la fonctionnalité du réseau ferroviaire français mettent en évidence que l'introduction puis le développement de la grande vitesse ferroviaire en France ont produit trois révolutions géographiques durables : une contraction globale et différenciée de l 'espace-temps ; une révolution réticulaire, marquée certes par la mise en réseau des régions mais aussi par une simplification du réseau fonctionnel (esquisse de hub) ; et l'émergence d'un archipel métropolitain, consécutif à l'extension des espaces accessibles et à la fragmentation spatiale créées par la grande vitesse.
Le réseau européen des Lignes à Grande Vitesse : espoir ou impasse ? (The European network of high-speed rail lines : hope or deadlock ?)
Authors: Troin Jean-François
Published: December 2014

Si la conception d'un réseau européen à grande vitesse est déjà ancienne (elle remonte à 1990), sa réalisation est aujourd'hui affectée par diverses impasses. Ces impasses sont à la fois politiques (pour leurs aménagements, les États auraient tendance à pratiquer le « chacun chez soi »), financières (difficultés à réunir des fonds pour Lyon-Turin), spatiales (importance des maillons manquants). Pourtant, ce grand projet qui a suscité tant d'espoirs progresse physiquement et mentalement. Des faits concrets en sont la preuve : la jonction qui se dessine enfin avec l'Espagne de Perpignan à Figuéras, un très prochain temps de trajet sur la liaison Paris-Londres en 2 h 15, la concertation améliorée avec l'Allemagne. Mais ce réseau prend du retard car il n 'est pas porté par une volonté politique commune et la Commission Européenne semblerait à nouveau sous le charme du transport routier libéralisé.
Essai sur l'iconographie des statues-colonnes de quelques portails du premier art gothique
Authors: Beaulieu Michèle
Published: December 2014

Les Bénédictins du XVIIIe siècle, voyaient dans les figures des ébrasements des premiers portails gothiques, des rois de France ; les exégètes modernes y ont reconnu des héros bibliques en suggérant parfois un accord entre la royauté et le sacerdoce. On sait, en outre, que les portails sont de vastes compositions anagogiques dont les programmes ne sont pas centrés sur l'Ancien Testament, mais ont toujours trait à la nouvelle Loi selon la doctrine typologique. Un essai d'identification des statues-colonnes passe donc, obligatoirement, par l'étude des textes théologiques.

Existe-t-il une corrélation entre la représentation des rois bibliques et l'ascension de la monarchie française accomplie au xne siècle en étroite liaison avec l'abbaye de Saint-Denis ? Textes et documents semblent le prouver.

Les trois portes de Saint-Denis, le Portail Royal de Chartres n'ont pas été étudiés, l'auteur se bornant à proposer des hypothèses pour quelques ensembles, laissant volontairement de côté ceux pour lesquels il n'a, présentement, pas de solution à proposer. Les portails se divisent en cinq groupes :

I. a) Statues exclusivement vétéro-testamentaires avec les figures de Moïse et d'Aaron (Saint-Maurice d'Angers, Notre-

Dame d'Étampes). 6) Melchisedech remplaçant Aaron (portails latéraux des cathédrales du Mans et de Bourges).

II. Statues vétéro-testamentaires associées aux saints Pierre et Paul

a) Avec Moïse et Aaron (Saint-Pourçain-sur-Sioule, Saint-Loup-de-Naud, Saint-Bénigne de Dijon, Nesle-la-Reposte,

Saint-Ayoul de Provins).

b) Melchisedech remplaçant Aaron, Moïse présent : Château-Chalon.

III. La porte Sainte-Anne à Notre-Dame de Paris est-elle un portail de la Vierge ou de la Vision apocalyptique ?

IV. Comment la série des Figurae Christi se modifie-t-elle aux portails où culmine le Couronnement de la Vierge ?

V. Enfin deux ensembles exceptionnels : celui du flanc nord de Saint-Benoît-sur-Loire, tentative d'adaptation du nouveau

programme des portails du Couronnement de la Vierge au thème traditionnel du Christ en Majesté, et le portail occidental de Saint-Germain-des-Prés qui semble évoquer la monarchie mérovingienne.

Authors: Baek Soyoon , Xia Xuikui , Min Byung Sun , Park Chanil , Shim Sang Hee
Published: December 2014

Seven compounds, including three neolignans 1–3, a norlignan 4, and three diterpenoids 5–7, were isolated from the feces of Trogopterus xanthipes. Structures of these compounds were identified by 1D and 2D NMR as well as MS. The absolute configurations of compounds 1, 2, and 4 were determined by comparing CD spectra and optical rotations. Among the isolated compounds, 1–3 were novel and subsequently named trogopterins A, B, and C, respectively. Likewise, compound 4 was isolated from nature for the first time. Cytotoxic activities of compounds 1–4 were evaluated. Compounds 1–3 exhibited moderate cytotoxic activities against HL-60 cells with IC50 values of 34.77–45.68 μM.
Les interventions comportementales intensives et précoces auprès des enfants avec autisme : une revue critique de la littérature récente
Authors: Cruveiller Virginie
Published: December 2014

Les interventions comportementales intensives et précoces (méthode aba , ou eibi , Early Intensive Behavioral Intervention ) font aujourd’hui l’objet d’un apparent consensus ; leur validité serait scientifiquement prouvée. Or, les données de la littérature scientifique sont bien plus divergentes et controversées qu’il n’y paraît. Cet article se propose de faire le point sur l’état actuel des connaissances en la matière, à travers une revue de la littérature récente (essais cliniques et méta-analyses parus depuis 2009). Si ce type d’intervention est probablement efficace sous certaines formes et pour certains enfants, comme l’attestent plusieurs essais cliniques, de nombreuses questions restent sans réponse, et le niveau de preuve général de ces études est grevé par un certain nombre de biais méthodologiques potentiels. De plus, certaines études montrent que l’intensivité d’une prise en charge n’est pas nécessairement corrélée à l’importance de ses effets. Les données actuellement disponibles – par ailleurs souvent en faveur de l’ eibi – restent donc lacunaires et discutables.

Soen est un bébé identifié par le protocole préaut comme présentant un retard de développement sévère et des signes de retrait autistique. Il est suivi dès l’âge de 5 mois et demi dans le cadre d’une consultation parents-bébé, qui suivra également son petit frère dès sa naissance au titre du risque des fratries ted . L’évolution de Soen se fera vers une entrée en relation, mais restera marquée par le retard de développement, donc probablement vers un ted-ns .
Remarques à propos du troisième Plan autisme (2013-2017)
Authors: Trouvé Jean-Noël
Published: December 2014

Le récent « plan autisme » du gouvernement a désagréablement surpris, non pas tant par son manque de moyens que par son univocité autoritaire en faveur des interventions éducatives, et par son exclusion de fait du service public de pédopsychiatrie des soins aux autistes ; loin de la logique de complémentarité intégrative que défendent beaucoup de professionnels et de familles.
Pulsion invocante avec les bébés à risque d'autisme
Authors: Laznik Marie-Christine
Published: December 2014

En confrontant la clinique avec des enfants autistes et les textes de Freud et ceux de Lacan, Marie-Christine Laznik a fait l’hypothèse que le troisième temps du circuit pulsionnel serait absent chez les enfants autistes. Testant cette hypothèse sur des films familiaux de bébés en voie de devenir autistes, elle s’est heurtée à une disparité étonnante chez ces bébés, habituellement fermés mais capables par moments d’entrer dans des interactions réussies. Imprégnée des travaux des psycholinguistes, elle a émis une autre hypothèse : celle de l’importance du mamanais dans les interactions avec ce type de bébé. Le mamanais , trace dans la voix de la mère du plaisir émerveillé suscité par son bébé, renvoie au troisième temps du circuit pulsionnel. Les bébés en sont avides dès la naissance, sans aucun étayage sur un objet du besoin. L’analyse acoustique des films familiaux de bébés qui sont devenus autistes, puis celle de séances de thérapie avec un bébé à risque autistique, ont montré que ces bébés peuvent répondre à l’appel de cette pulsion invoquante, lorsqu’un adulte est capable de ce type de prosodie. Cependant, cela reste rare car ces bébés ne jouent pas leur rôle dans cette interaction avec l’adulte.
Les résultats des élections communales du 14 octobre 2012 en Flandre
Authors: Blaise Pierre
Published: December 2014

Le 14 octobre 2012 ont eu lieu dans les communes belges les élections pour le renouvellement des conseils communaux. Le présent Courrier hebdomadaire est consacré à la présentation des résultats de ce scrutin dans les 308 communes de la Région flamande. Les performances électorales des principaux partis politiques sont tout d’abord appréhendées d’un point de vue global. Le nombre de sièges obtenus et les positions majoritaires sont recensés. L’analyse montre que le parti présentant l’ancrage local le plus fort reste le CD&V, désormais suivi par la N-VA. Viennent ensuite, dans l’ordre, l’Open VLD, le SP.A et Groen. Quant au Vlaams Belang, il est en net recul. L’exposé est appuyé par des cartes figurant les zones d’implantation de ces six partis. Une étude des résultats électoraux de 2012 est ensuite réalisée par province et par arrondissement. Des tableaux établis par arrondissement présentent, pour les quatre derniers scrutins, la liste arrivée en tête dans chaque commune de plus de 10 000 habitants. Ils précisent si cette liste a remporté la majorité absolue des suffrages et donc des sièges, la majorité absolue des sièges uniquement ou seulement la majorité relative des voix et des sièges. La situation des villes flamandes de plus de 50 000 habitants – dont Anvers, enjeu majeur de cette élection – est traitée de manière spécifique. Une analyse est également consacrée à l’élection des conseils de district à Anvers. Enfin, Pierre Blaise présente de manière détaillée la situation dans les communes situées en périphérie bruxelloise et le long de la frontière linguistique. L’évolution politique de ces communes appelle en effet un examen particulier, dans la mesure où celles-ci constituent des lieux de fixation du contentieux communautaire. En l’occurrence, on constate un recul de la polarisation linguistique de l’élection dans ces communes, marquée par un progrès des listes bilingues.
Foreign Land Acquisition
Authors: Ajiboye Olanrewaju E. , Yusuff Olabisi S.
Published: December 2014

Land grabs, a recent phenomena, have been documented to have effects on the activities of the indigenous farmers. This chapter examines the impact of foreign land acquisitions on food security and food chain in Nigeria. Quantitative and qualitative methods of data collection were adopted. A total number of 250 respondents were included in the quantitative sample, and 20 In-Depth Interviews (IDI) were conducted with opinion leaders. The study found the nexus of interaction between foreign land acquisition, commercialization of agriculture, food security, and food chains in Nigeria. The study recommended that the government should not make the process of land acquisition too cumbersome for interested people or agencies to acquire; the government should make efforts to encourage interested local investors in large-scale farming to allow competition to increase food production as well as to sustain the agricultural sector of the national economy.
Research as Curriculum Inquiry
Authors: Bird Jennifer Lynne , Wanner Eric T.
Published: December 2014

Research sometimes leads to new discoveries and new directions other than the ones originally intended. This chapter began as a study using both quantitative and qualitative methods to learn about the connections between writing and healing. College students who wrote in journals throughout the semester as part of normal classroom practices for an education methods class in reading and writing completed surveys answering questions about their writing and their health. The original goal was to add insights to studies completed a quarter century ago by other researchers to assess similarities and differences. Initial analysis of the data echoed the findings of previous studies: writing is healing. However, the more important observation became that on one of the health survey questions, 92% of the subjects reported experiencing anxiety or stress. Consequently, the research evolved into a social action project to help college students cope with stress and anxiety.
Overview of Impacts of Distribution Generations and Micro Grids on Active Distribution Network Operation
Authors: Yu Lei , Zhao Tian Yang , Wu Xu , Zhang Jian Hua
Published: December 2014

With recent development of technology and management in power market and equipment, more and more distributed generation (DG) is embedded in the distribution network. However the approach of connecting DG in most cases is based on a so-called ‘fit and forget’ policy and the capacity of DG is limited rigidly by distribution system operator to avoid the negative effects of high level penetration. New management technologies have been proposed to handle the integration of DGs in the distribution networks. In this review, the micro grid (MG) was treated as the local control method to coordinate DGs within a small area of distribution network. And the active distribution network (AND) was treated as the global control mechanism to actively manage DGs, MGs and other equipment. The operation framework of ADN was firstly introduced. Then based on the static and dynamic models of DGs and MGs, impacts of DGs and MGs on the ADN are surveyed from power quality, stability to the operation. Finally, the conclusion and suggestion is given in this paper.

Authors: Zhou Wan Qiu , Li Xin , Huang Ting Ting , Wang Jian , Xin Shi Gang , Kang Yan Hong
Published: December 2014

Polyaniline (PANI) polymer coating was electrochemically synthetised by cyclic voltammetry (CV) method on stainless steel bipolar plates of proton exchange membrane fuel cell (PEMFC). Structure and morphology of PANI polymer coating were characterized by means of fourier transform infrared reflection (FTIR) spectrum and scanning electron microscopy (SEM). The corrosion behavior of the coating was evaluated by polarization curve and electrochemical impedance spectroscopy (EIS) in the medium of 1M H2SO4and 2ppM NaF at 70°C to simulate the corrosive condition of PEMFC. It was found that the optimal conditions for PANI polymer coating synthesis could be 10-15 circles when the voltage ranged from-1.2V to +1.2V(Vs.SCE) with a scan rate of 50 mV/s. SEM observation results indicated that the polymer coating presented with uniform and dense feature. FTIR results illustrated that the coating were composed of PANI. Corrosion current densities of 316L SS and PANI-coated steel were 10-5and 10-6A/cm2respectively. Corrosion potential of the coated SS shifted towards more positive values compared to the uncoated plate. EIS results indicated that the radius of the capacity impedance for PANI increased obviously.

Authors: Xiang Kun , Yang Yan Ling , Li Xing , Zhang Da
Published: December 2014

Oxidant flushing of the raw water distribution system (RWDS) affects the degradation of dissolved organic matter (DOM). The characteristic of DOM after chlorine (NaOCl), chlorine dioxide (ClO2) and their combination (NaOCl/ClO2) were evaluated by dissolved organic compound (DOC), spectrophotometry and fluorescence of DOM in simulated RWDS. The results suggested that oxidant flushing had negative effect on DOC removal, especially for NaOCl/ClO2, but it was resumed with a higher recovery rate compared to ClO2 and NaOCl. The biodegradable of DOM increased after oxidant flushing, and related to DOC degradaion. Overall fluorescence of DOM intensity has a decrease potential after oxidant flushing, particularly for tryptophan-like fluorescence. These results indicated that NaOCl/ClO2 has less negative impact on the resume of DOM degradation in RWDS compared with corresponding single oxidant.

Published: December 2014

According to functional characteristics of different regions of the ventilation network, the complicated ventilation network can be further divided into non-overlapping and exhaustive safety subregions, which can provide scientific basis on classification guidance for ventilation analysis in a concise point of view. Therefore, it is of great application significance. Specifically, a method is proposed to divide safety subregions of the ventilation network. Then, six different safety subregions are defined, and they are air-inlet subregion, air-outlet subregion, air-consuming subregion, upstream of air-consuming subregion, downstream of air-consuming subregion and bypass subregion. After that, with an air-consuming spot (working face and heading face) as the center, depth-first search (DFS) algorithm is adopted to perform traversal analysis on coalmine ventilation network. Besides, ventilation network partition is achieved in combination with safety subregion partition algorithm. The method proposed here can be used for coalmine safety production analysis and management. Finally, Huangling coalmine is taken as an example to verify the correctness and feasibility of the method proposed.

Thus, they predict quantum gravity corrections to various quantum phenomena. The GUP gives rise to two additional terms in any quantum mechanical Hamiltonian, proportional toandrespectively, where is the GUP parameter. By considering both terms as perturbations .We compute such corrections to the two typical potentials: parabolic potential toand Dirac potential to.
