Unilateral synostosis of the zygomaticotemporal suture associated with mandibular coronoid process impingement in a dog
Authors: Fraga-Manteiga E. , Schwarz T. , Clements D. N. , Ryan J. M.
Published: May 2013

A 13-month-old dog was investigated for the complaint of open-mouth locked jaw. There were not any previous episodes of trauma witnessed. Computed tomographic evaluation revealed unilateral zygomaticotemporal synostosis and associated craniofacial asymmetry, with impingement of the mandibular coronoid process resulting in unilateral temporomandibular joint subluxation. Closed reduction of the subluxation was not maintained. Partial zygomaticotemporal suturectomy resulted in resolution of the clinical signs. To the author's knowledge, isolated zygomaticotemporal synostosis with associated temporomandibular subluxation has not been reported in the dog.

Published: May 2013

3-[18F]Fluoropropanesulfonyl chloride, a recently proposed prosthetic agent for fluorine-18 labelling, was prepared in a two-step radiosynthesis via 3-[18F]fluoropropyl thiocyanate as an intermediate. Two benzenesulfonate-based radiolabelling precursors were prepared by various routes. Comparing the reactivities of 3-thiocyanatopropyl nosylate and the corresponding tosylate towards [18F]fluoride the former proved to be superior accounting for labelling yields of up to 85%. Conditions for a reliable transformation of 3-[18F]fluoropropyl thiocyanate to the corresponding sulfonyl chloride with the potential for automation have been identified. The reaction of 3-[18F]fluoropropanesulfonyl chloride with eight different aliphatic and aromatic amines was investigated and the identity of the resulting 18F-labelled sulfonamides was confirmed chromatographically by comparison with their nonradioactive counterparts. Even for weakly nucleophilic amines such as 4-nitroaniline the desired radiolabelled sulfonamides were accessible in satisfactory yields owing to systematic variation of the reaction conditions. With respect to the application of the 18F-fluoropropansulfonyl group to the labelling of compounds relevant as imaging agents for positron emission tomography (PET), the stability of N-(4-fluorophenyl)-3-fluoropropanesulfonamide against degradation catalysed by carboxylesterase was investigated and compared to that of the analogous fluoroacetamide.

Published: May 2013

La Première Guerre mondiale donne naissance en Asie à une nouvelle donne en termes de pouvoirs, et modifie les rapports du Japon au sein du système d’alliances dans lequel il se trouvait alors. La guerre, en apparence simple conflit direct avec l’Allemagne, recouvre en réalité pour le Japon plusieurs conflits, militaires et diplomatiques. Enfin, le visage nouveau de cette guerre, totale, allait influencer grandement le Japon dans son rapport à la guerre et aux colonies.
Historiographie japonaise de la guerre de 1931 à 1945 : état des recherches jusqu'à nos jours
Authors: Matsunuma Miho
Published: May 2013

La recherche historique japonaise portant sur la guerre durant les années 1931 à 1945, qui débute dès la fin du conflit et se développe depuis dans une totale liberté de recherche, est particulièrement marquée par une culture de gauche. La perception critique du régime qui a mené la guerre et du pouvoir conservateur d’après-guerre y représente la tendance majoritaire. Cette science historique connaît un tournant décisif dans les années 1990 avec une remise en question du cadre de réflexion jusque-là fondamental, à savoir celui d’une histoire nationale et linéaire. Ainsi, des historiens, en ce début de XXI e siècle, essaient d’appréhender cette période dans un contexte plus large, à la fois dans le temps et dans l’espace.
La gestion des colonies et l'administration militaire dans le Sud : Le démantèlement de l'Empire japonais en Asie du Sud-Est
Authors: Nakano Satoshi
Published: May 2013

Pendant la guerre du Pacifique en Asie, un vaste territoire en Asie du Sud-Est est occupé par l’armée japonaise. Son administration de cette zone, visant initialement à bâtir un nouvel ordre, est en réalité largement dépendante des anciennes structures de la colonisation occidentale. Le Japon mène une politique d’oppression et d’exploitation des populations, tandis qu’il accorde dans le même temps certaines libertés aux élites locales qui revendiquent leur autonomie. Cette rencontre avec les « autres » amène les Japonais à prendre conscience de l’impossibilité de la mise en place d’une Sphère de Coprospérité de la grande Asie de l’Est dirigée par le Japon.
La voix des juges français dans les procès de Nuremberg et de Tokyo. Défense d'une idée de justice universelle
Authors: Schöpfel Ann-Sophie
Published: May 2013

Les procès de Nuremberg (1945-1946) et de Tokyo (1946-1948) furent une « première » à laquelle la France participa dans le but de punir les « grands criminels de guerre ». L’histoire réclamait un jugement rapide. Les juges français en firent pourtant abstraction. Ils exprimèrent leur différence en critiquant le cœur des procès. Si leur position inédite ne fut pas prise en compte à l’époque, leur héritage dans l’émergence du droit international mérite d’être découvert.
Il y a 70 ans, Philippe Kieffer invente les Commandos marine français. Histoire et mémoires du Commando Kieffer
Authors: Simmonet Stéphane
Published: May 2013

Le 6 juin 1944, 177 hommes commandés par Philippe Kieffer prennent pied en Normandie dans le secteur britannique Sword. Le “Commando Kieffer” est ce jour-là la seule unité française engagée dans le débarquement terrestre d’Overlord. Condamnés à n’être dans la mémoire collective que les “Français du Jour J”, les hommes de Kieffer ont ainsi vu leur histoire et la mémoire de leur action largement amputées, oubliées, voire déformées depuis cet été 1944. Cet article revient sur ces « trous de mémoire » en tentant d’établir la véritable identité du bataillon français depuis sa formation en 1942 jusqu’à sa dissolution en juillet 1945 : une force militaire impliquée dans des raids en 1943, des combats aux Pays-Bas et en Allemagne au cours de l’automne 1944 et au début de l’année 1945. Au centre de cette trajectoire, la figure du chef, le père fondateur du Commando n’est pas oublié, ce « civil en uniforme » qui lèguera à la marine française les structures de ses futures unités commando et donnera son nom à un 6 e Commando de fusiliers marins créé en 2008. Cet article enfin aborde les différentes représentations du “Commando Kieffer” au sein de différentes mémoires sociales, celle des Britanniques, celle de la France Libre, celle de la marine française...
À propos de la « Porte Noire » de Besançon et de la « Porte de Mars » de Reims
Authors: Blonce Caroline
Published: May 2013

Moins célèbres et moins étudiés que leurs homologues de Narbonnaise (Orange, Glanum), les arcs de Besançon (Germanie Supérieure) et de Reims (Gaule Belgique) n’en sont pas moins de magnifiques exemples de l’urbanisme et de l’art monumental romains. Le but du présent article est d’offrir une étude détaillée et comparée de ces deux édifices, faisant ainsi ressortir la profonde originalité de leur décor figuré, mais aussi la proximité qui existe entre eux. L’attention portée aux détails de ce décor (grâce notamment à une restauration de grande ampleur à Besançon) permet de mieux comprendre le contexte de création de ces arcs et, de ce fait, d’avancer une nouvelle proposition de datation : la fin du règne de Marc Aurèle. Les deux arcs sont ainsi replacés dans le contexte des campagnes germaniques et du triomphe célébré par Marc Aurèle et Commode en 176 ap. J.-C. Ces deux monuments reflètent la pénétration de la culture gréco-romaine, à travers les mythes, dans les provinces occidentales de l’empire romain. Ils attestent également l’importance de la mise en scène du pouvoir impérial dans l’espace de la cité, à travers l’urbanisme.
Une chancellerie complexe. La production d'actes dans l'entourage comtal pendant l'union personnelle des comtés de Flandre et de Hainaut (1191-1244)
Authors: De Paermentier Els
Published: May 2013

Faisant suite aux études de Thérèse de Hemptinne et de Walter Prevenier, cette contribution tente de formuler une réponse à des questions concernant le fonctionnement de la chancellerie de Flandre sous les successeurs du comte Philippe d’Alsace († 1191) : Comment la chancellerie comtale a-t-elle évolué jusqu’au milieu du xiii e siècle ? Quelles personnes étaient responsables de l’expédition et de la confection des chartes comtales ? Quelles formes d’organisation la chancellerie a-t-elle prises, et peut-on parler d’un concept univoque de « chancellerie » ? L’existence d’une union personnelle entre les comtés de Flandre et du Hainaut depuis 1191 a influencé ce questionnement, à savoir comment les activités de chancellerie se sont-elles développées par la suite dans les deux comtés administrés par les mêmes princes(ses). Afin de pouvoir répondre à ces questions, trois approches méthodologiques ont été utilisées, à savoir une analyse diplomatique du dictamen des actes comtaux, une étude paléographique des originaux conservés et un inventaire prosopographique du personnel de la chancellerie. La base de données Diplomata Belgica s’est révélée d’une valeur inestimable pour chacune de ces approches. Les résultats de l’étude ont abouti à une nouvelle compréhension de la participation de la chancellerie comtale de Flandre-Hainaut au processus de la « révolution de l’écrit », et de la bureaucratisation dans les Pays-Bas méridionaux au début du xiii e siècle. Finalement, les conclusions nous ont porté à nuancer quelque peu la définition d’une « chancellerie princière territoriale ».
La rivalité des pardons. Géographie politique de la grâce dans le royaume de France et les Pays-Bas bourguignons, de Charles VI à François Ier
Authors: Dauphant Léonard
Published: May 2013

L’étude du ressort des lettres de rémission permet de mesurer l’impact de la justice du roi de France au sein de son royaume, et donc de territorialiser et de quantifier la souveraineté. Le roi accorde sa grâce dans tout le royaume, sauf trois principautés (Bretagne, Barrois, Guyenne anglaise). Les rémissions émises par les chancelleries princières sont moins nombreuses et bien plus mal conservées (Barrois). La grâce du roi domine très largement dans le royaume, y compris dans les principautés de l’intérieur (État Bourbonnais). Seuls les Pays-Bas bourguignons font exception, à cheval entre Empire et royaume. Une étude quantitative des rémissions octroyées par les deux chancelleries (royale et ducale) dans un même territoire, l’Artois et la Flandre, est possible pour les années 1498-1502. Elle montre leur concurrence ainsi qu’un partage coutumier de l’espace des Pays-Bas bourguignons entre l’appel auprès de la chancellerie de Paris (Artois) et l’appel auprès de la chancellerie de l’archiduc (Flandre flamingante), la Flandre wallonne étant partagée. Ces pratiques suggèrent que la souveraineté royale a survécu en Artois jusqu’au règne de Charles Quint, portée par une pratique populaire du recours au roi contre la justice ducale. La souveraineté, ici redéfinie comme justice en dernier ressort reliant la capitale et les sujets du duc, ne survit pas à la guerre des années 1520 qui impose une frontière fondée sur la domination militaire.
Le parlement de Savoie (1536-1559), un outil politique au service du roi de France, entre occupation pragmatique et intégration au royaume
Authors: Houllemare Marie
Published: May 2013

Le parlement de Chambéry n’eut qu’une existence éphémère pendant l’occupation française de la Savoie (1536-1559). Pour rendre compte de son activité, les chercheurs disposent de sources variées : registres parlementaires des édits-bulles, correspondances administratives et procès-verbaux d’enquête, mais aussi papiers personnels du président Pellisson. Leur confrontation atteste que cette institution, loin de se limiter à rendre justice, servait aussi à consolider la conquête, en assumant par exemple une fonction de logistique militaire et de surveillance des frontières. Elle participait plus généralement de l’affirmation de la souveraineté française dans une région restée en partie fidèle au duc de Savoie, en tentant de susciter la confiance des élites locales et en manifestant la bonne volonté du roi à l’égard de ceux qui lui obéissaient. Enfin, son activité était marquée par les efforts d’unification administrative du royaume au milieu du xvi e siècle, passant plus par la circulation et la surveillance des magistrats que par la procédure.
Le savoir contemplatif : les religieuses et les limites de la connaissance (Espagne, xvie siècle)
Authors: Roullet Antoine
Published: May 2013

Cet article propose de revenir sur le rapport des religieuses à la culture savante en réévaluant leurs appropriations du savoir théologique. Il s’appuie sur un dépouillement de leurs autobiographies spirituelles et de l’hagiographie des carmélites espagnoles, entre les années 1560 et les années 1630. Il met en évidence quatre postures vis-à-vis du savoir lui-même : l’ignorance feinte, la mise en scène du doute, la préservation du mystère et la mise en œuvre d’une herméneutique du savoir visionnaire. Toutes ces attitudes expliquent les incertitudes et les ambiguïtés qui caractérisent l’écriture des religieuses, que l’historiographie a jusqu’ici justement analysée comme les signes d’une rhétorique défensive féminine, voire féministe, face aux censures masculines et inquisitoriales. Mais le flou savamment entretenu de leur prose dès lors qu’elle traite du mystère participe aussi d’une démarche moins genrée, celle de la construction et de la préservation de la croyance.
L'autre côté de la barricade : perceptions et pratiques policières en mai et juin 1968
Authors: Mathieu Lilian
Published: May 2013

Les affrontements entre étudiants et forces de l’ordre ont nourri la dynamique protestataire de mai 1968, et leurs images sont aujourd’hui au cœur de la mémoire de l’événement. L’article se penche sur ces interactions conflictuelles en privilégiant le point de vue policier. Il se base pour cela sur l’étude des archives policières de la préfecture de Paris et des départements du Rhône et de la Loire. Après avoir présenté l’organisation des troupes mobilisées et les enjeux de leurs modes d’intervention, l’article étudie les fluctuations conjoncturelles des modalités du maintien de l’ordre : à une première phase de désajustement des anticipations et des pratiques policières succède, à partir du 13 mai, une phase de suspension de la présence et de l’activité des forces de l’ordre ; celle-ci s’achève aux alentours du 24 mai par une radicalisation du conflit et une reprise des affrontements violents. Mises en échec pendant une partie de la crise, les forces de l’ordre sauront par la suite tirer les leçons de mai 1968 en matière d’équipement et d’organisation du maintien de l’ordre.
La mediación intercultural en las asociaciones de inmigrantes de origen africano
Authors: Llevot Calvet Núria , Garreta Bochaca Jordi
Published: May 2013

El artículo analiza cómo realizan la mediación intercultural las asociaciones de inmigrantes de origen africano de tres comunidades autónomas (Cataluña, Valencia y Navarra) y qué caracteriza a sus actores. El análisis se basa en una encuesta realizada a 206 asociaciones de inmigrantes y en 30 entrevistas: 15 a directivos, 10 a administraciones y entidades que trabajan con ellas, y 5 a inmigrantes no asociados. Los resultados apuntan a que las asociaciones son espacios de convivencia, pero una parte importante de ellas carece de objetivos específicos claros en sus planteamientos de trabajo con sus usuarios y otros agentes sociales. También hemos visto que la mediación es una práctica incipiente en las asociaciones, al contrario de lo que sucede en el seno de las instituciones españolas del ámbito educativo, sanitario y familiar. Por otra parte, hemos apreciado que las asociaciones africanas desvirtúan, a menudo, el concepto de mediación considerándola simplemente como una conversación entre los suyos.

Published: May 2013

Engineering students are required to have, by the time of graduation, a set of professional skills related to teamwork, oral and written communications, impact of engineering solutions, life-long learning, and knowledge of contemporary issues. Teaching and assessment of these skills, as part of ABET accreditation, remains problematic. A systematic methodology to integrate these skills and their assessment in the curriculum is described. The method was recently applied in several engineering programs and proved to be efficient in generating data and evidences for evaluation and continuous improvement of these outcomes.
Experimentation in a Research Workshop: A Peer-learning Approach as a First Step to Scientific Competence
Authors: Ossenberg Philipp , Jungmann Thorsten
Published: May 2013

Engineers are supposed to be clever innovators and creative problem solvers. First-year engineering students usually do not learn to solve technical problems creatively. They usually do not learn how to innovate. In this paper we describe FLExperiments as a new learning format in a research-based learning environment named FLEx-Forschungswerkstatt (research workshop). FLEx provides student-focused, competence-oriented and research-based learning. Conducting FLExperiments means that students solve small technical problems by experimentation and subsequently document their findings in a scientific report. In this learning process they are assisted by their peers, who act as tutors. FLExperimentation includes the iterative process of experiential learning synchronized with a research process. To demonstrate the idea of FLExperimentation we are giving the example of an experiment from the field of kinetics: the Loop.

Published: May 2013

Laboratory experiments play a significant role in engineering education. The main concern of the described hands-on miniLABs initiative (as a work in progress) is lowering the hurdles in order to provide engineering students with an informal and straightforward access to experiments carried out in labs of the IUL at TU Dortmund University. miniLABs will offer students different, short and voluntary hands-on lab sessions, consisting of two different modes and different aspects related to manufacturing technology in the field of forming processes. In small teams, students can get in touch with practical engineering activities in the fields of present scientific research, either to study a certain phenomenon or to look at a wider engineering context. Based on the framework of experiential learning, miniLABs tries to foster the shift from teaching to deep learning. Finally, this initiative aims to inspire young students for real and hands-on engineering experiments and to contribute to the science education of these young and future engineers.
Research about Influencing Factor on Interpolation Accuracy in Data Exchange of Fluid-Structure Interaction
Authors: Shen Zhen , Wang Biao , Yang Hui , Zheng Yun
Published: May 2013

Six kinds of interpolation methods, including projection-shape function method, three-dimensional linear interpolation method, optimal interpolation method, constant volume transformation method and so on, were adoped in the study of interpolation accuracy. From the point of view about the characterization of matching condition of two different grids and interpolation function, the infuencing factor on the interpolation accuracy was studied. The results revealed that different interpolation methods had different interpolation accuracy. The projection-shape function interpolation method had the best effect and the more complex interpolation function had lower accuracy. In many cases, the matching condition of two grids had much greater impact on the interpolation accuracy than the method itself. The error of interpolation method is inevitable, but the error caused by the grid quality could be reduced through efforts.

Characteristics and Elimination of Vibration Transfer on Small- and Medium-Sized Turbo Generators
Authors: Zhang Rong Pei , Lu Sheng Yang
Published: May 2013

Vibration control is important for the safe and stable operation of generator units. The vibration transfer characteristics of small- and medium-sized turbo generators are different from those of large capacity units due to differences in mechanical structures. We point out that the vibration on small- and medium-sized turbo generators propagates through their foundation from one bearing to another, rather than through the shafting. In particular, transmission of horizontal vibration measured on bearings is found to be more significant compared with vertical and axial vibration due to the height of the bearing pedestal. We demonstrate through three successful diagnostic practices the process of vibration transmission on small and medium-sized turbo generators. The present work can serve as a reference for the same type of unit as well as other similarly structured rotating machineries.

Numerical Simulation of Oil Film State and Mechanical Performance of Heavy Hydrostatic Thrust Bearings
Authors: Hong Yao Yao , Du Li Jun , Qi She Miao
Published: May 2013

The finite element method (FEM) is applied in the numerical simulation of heavy hydrostatic thrust bearings to study the influence of pressure and temperature on bearing deformation. The pressure distribution and the temperature distribution are obtained by solving the Reynolds equation and the energy equation. The bearing deformations caused by temperature and pressure are computed by imposing the two obtained distributions on the bearing. Because the pressure distribution and the temperature distribution are influenced by the oil film thickness and the oil film thickness is influenced by the bearing deformation, the numerical simulation is a process of iteration. The numerical results demonstrate that, in heavy hydrostatic thrust bearings, the thermal deformation and the mechanical deformation are both significant and can not be neglected. The influence of operation parameters on the anti-capsizing capability of heavy hydrostatic thrust bearings is also discussed. The obtained results reveal that, the anti-capsizing moment of the bearing increases with the decrease of the central thickness of the oil film.

During prestressed cementing for heavy oil thermal recovery wells, it is encountered that the earth anchor connecting to the bottom of the casing string anchors difficultly, and anchoring force can not meet design requirement. A new type of unit and resettable earth anchor structure for prestressed cementing is introduced. The project can use multiple unit combination according to different formation condition and can choose different length of the earth anchor fluke according to diameter of the well. ANSYS/LS-DYNA is used to simulate the process of the fluke digging into the wall of the borehole with different diameter. Variation of reaction force of rock upon the fluke with different initial digging angle is analyzed, and the most favorable angle range in which the fluke digs into the borehole wall is concluded. A favorable reference to determining fluke's geometric parameter and selecting type of the claw is provided.

Published: May 2013

As is well known, almost all the machines need to start and brake. In this process, the lubrication state of their parts changes instantaneously. In this paper, an isothermal study for the line contact elastohydrodynamic lubrication (EHL), which is in rapid braking process and under a constant load, is carried out by using a simplified multigrid method. Numerical results indicate that the oil film thickness decreases and the oil film pressure increases with the decrease of the speed during the process of rapid braking. The oil film shrinks quickly and the oil entrapment occurs when the speed reduces to a certain range. Simultaneously, the distribution of oil film pressure tends to the central lubrication area. The size of the oil entrapment area and the changes of the oil film pressure are closely related to the braking time and the initial speed, which reflects the transient effects of the lubricating oil film.
