La ville noire, terre de migrations bretonnes : Trélazé, 1850-1914
Authors: Fauchet Catherine , Hugues Nathalie
Published: March 2011

Ville ouvrière largement fondée sur la mono-industrie de l'ardoise, Trélazé devient à partir du milieu du XIXe siècle une terre d'exil pour de nombreux Bretons. En 1900, ils représentent 20 % de la population trélazéenne puis 50 % à partir de 1908. L'arrivée massive des Bretons à Trélazé de 1860 à 1914 répond à des conditions économiques et sociales particulières, d'une part en Bretagne où l'exode est très important, et d'autre part à Trélazé où l'augmentation de la production d'ardoise, corrélative à un accroissement de la demande, accentue les besoins en main-d'œuvre.

La majeure partie de la colonie bretonne s'installe au cœur de la cité et prend le nom de Petite Bretagne. Mais cette population mobile n'hésite pas à partir à nouveau lorsque les conditions économiques deviennent difficiles. Les dirigeants des ardoisières, conscients de cette mobilité, tentent, par des mesures sociales spécifiques à la communauté, de maintenir à Trélazé l'essentiel de cette main-d'œuvre.
Les « ravages du combisme » dans le Trégor ?
Authors: Forestier Yann
Published: March 2011

The most accessible sources (the press and litterature) touching on the situation in the district of Lannion at the tinte of the religious quarrel (1901-1906) mention crises similar to those which shock most catholic regions at the same lime. A prefectoral records' consultation (1M, 3M and V series of the Côtes-d'Armor departemental Public Records) on a longer term brings us to qualify the view. The events took place in a context of public opinion suspicion towards the traditionnal social authorities (aristocracy and clergy) and of an arising republican opinion. The enforcement of the actually relatively pragmatic radical cabinets' polilical, religious and administrative measures triggered an opposition that was rather organized by the local worthies than really spontaneous. Far from disparaging the Republic in the opinion of voters who were just discovering it, the combist policy confirmed the public opinion' s changes. The main point in the Trégor political history at the beguinning of this century is not as much the religious quarrel, which appeard only in the background, as the massive and fast support from a majority of the electorale to the republican view.
Le territoire symbolique et révélateur. Finistère et Front National : l'inadéquation culturelle
Authors: Richard Jean-Luc
Published: March 2011

Les récents scrutins électoraux ont permis à J.-M. Le Pen, au niveau national, avec 15 % des voix, d'accroître son nombre d'électeurs et son influence politique. Mais, en Basse-Bretagne, sa région natale, il obtient toujours des scores faibles, sauf sur le littoral, et ne progresse pas. Cet article, à partir de l'analyse des résultats dans le Finistère, met en évidence quels sont les facteurs historiques et socio-économiques qui expliquent cette résistance de la Bretagne bretonnante. Le caractère égalitaire des relations familiales et la forte activité professionnelle féminine jouent un rôle de premier ordre, dans un département où la population étrangère est très faible. L'influence du catholicisme et l'identité culturelle bretonne semblent aussi constituer des raisons déterminantes qui expliquent la modestie des succès rencontrés par le FN en Bretagne occidentale. Dans ce contexte particulier, les caractéristiques individuelles qui concourent à une prévalence en faveur du vote Front national apparaissent nettement.

Élites et notables des Côtes-du-Nord : (années 1930-1950)
Authors: Bougeard Christian
Published: March 2011

Notables et élites locales sont les médiateurs et les acteurs de la vie politique. À partir de l'exemple des Côtes-du-Nord, il s'agit d'évaluer l'impact de la Deuxième Guerre mondiale sur les élus, en dégageant les continuités et les évolutions. L'épuration de Vichy est limitée. Un fort renouvellement des hommes s'opère en 1945 et après, aussi bien au plan politique (poussée à gauche en 1945, retour de la droite indépendante au début des années 1950) qu'en termes de générations (élimination des notables de l'entre-deux-guerres) et d'origines socio-professionnelles : les agriculteurs progressent, les professions libérales déclinent au profit d'autres actifs. L'accès à la notabilité politique s'élargit.
Le comte de Plélo (1699-1734), gentilhomme breton du siècle des Lumières
Authors: Frostin Charles
Published: March 2011

Le nom du comte de Plélo, ambassadeur de France à Copenhague, est passé à la postérité pour sa mort héroïque, en 1734, devant Dantzig en tentant de secourir le roi de Pologne Stanislas Leczinski assiégé par les Russes. Cette figure emblématique de la vieille Histoire de France mérite cependant de retenir l'attention à d'autres titres. Issu d'une famille bretonne d'ancienne extraction, pourvue de belles alliances et très fortunée, le comte de Plélo était devenu, par son mariage en 1722 avec une Phélypeaux, le beau-frère des secrétaires d'État Louis Phélypeaux, comte de Saint-Florentin, et Jean- Frédéric Phélypeaux, comte de Maurepas. Et, dix-huit ans plus tard, union encore plus prestigieuse, sa fille unique, Louise-Félicité de Bréhan, épousera un Duplessis-Richelieu, le célèbre duc d'Aiguillon, futur « commandant en chef » en Bretagne et futur ministre d'État. Par ailleurs, sociétaire du Club de l'Entresol, sorte d'Académie des sciences morales et politiques, le comte de Plélo brilla par l'étendue de sa curiosité, passionné notamment d'informations sur la jeune Russie pétrovienne. Jouissant du triple privilège de la naissance, de la fortune et de la culture, ce personnage revêt ainsi une dimension à la fois sociale et intellectuelle. Membre représentatif de cette noblesse bretonne de cour d'autant plus ménagée par le pouvoir que l'ancien duché restait un pays volontiers séditieux, Plélo l'est également de l'intelligentsia nobiliaire de haut rang qui, dès le début du siècle des Lumières, s'intéressa de près aux idées nouvelles et à leur diffusion.
Les noms révolutionnaires des communes de Maine-et-Loire
Authors: Denéchère Yves
Published: March 2011

The upheavals of the French Revolution have spared neither time nor space. As in all French « départements », the « communes » of Maine-et-Loire have been affected by some name changes. Their study is specially interesting since the toponymy « communale » of this « département », greatly hit by the « guerre de Vendée », is deeply converted to christianity. An exhaustive inventory and a cartography of the revolutionary names of the Maine-et-Loire communes enable to define highly different attitudes as to the « districts » regarding secularization. Some areas and poles of revolutionary activism, as well as areas of status quo, even refusal, and to finish with more contrasted zones quite clearly appear. The revolutionary toponymy also enables to clarify the partplayed by the authorities of the « département » and the districts, and the importance of the local revolutionary actors in the process of dechristianization. The actual use of the « communes » revolutionary names has been modest, as are the traces left in contemporary toponymy.
Réflexions sur la stratification sociale dans les villages de l'Ouest de la France (XIe-XIIIe siècles)
Authors: Pichot Daniel
Published: March 2011

Travailler sur la stratification sociale des villages de l'Ouest de la France à l'époque féodale, c'est aborder un territoire assez peu étudié d'abord en raison des sources dont la rareté et la nature ne facilitent pas la tâche. La société villageoise ne se résume pas à une masse plus ou moins uniforme de paysans dominés mais on ne peut guère aujourd'hui envisager de l'encadrer dans une typologie trop rigide. La réflexion menée ici essaie d'inventorier les facteurs qui peuvent influer sur la différenciation sociale. Le statut juridique et le rapport au pouvoir pèsent largement dans la définition des groupes mais les modalités du jeu s'avèrent plus élaborées qu'on ne l'avait imaginé et inversent parfois ce que l'on juge être la hiérarchie sociale. Les facteurs économiques, jamais absents, semblent prendre de la valeur avec le XIIIe siècle mais leur portée demeure difficile à apprécier avec certitude. D'autres facteurs enfin seraient à prendre en considération pour une analyse plus affinée.
Enseignement de l'histoire et histoire locale (1880- 1980)
Authors: Héry Evelyne
Published: March 2011

L'enseignement de l'histoire au lycée, tel qu'il a été organisé sous la Troisième République à des fins culturelles et civiques, exclut l'étude de l'histoire locale et régionale. Ainsi, l'histoire de la Bretagne s'apprend-elle uniquement au début du siècle dans les établissements secondaires confessionnels, et cette situation perdure malgré une demande sociale croissante et des soutiens politiques locaux de plus en plus diversifiés, puisque la loi Deixonne relative à l'enseignement facultatif des langues et cultures régionales date de 1951 et les premières circulaires d'application de la fin des années 1960. Dans un enseignement institué pour forger la conscience républicaine, l'enseignement de l'histoire régionale inspire en effet une défiance rémanente. Dès lors, l'institution scolaire a fait de l'histoire locale une interprétation minimaliste et l'a encouragée seulement comme moyen pédagogique, sans jamais la considérer comme un objet d'enseignement à part entière, amputant ainsi la connaissance et la réflexion des élèves d'une dimension dont la recherche historique montrait parallèlement toutes les potentialités.
Métallurgie et défrichement en forêt de Paimpont au Moyen Âge
Authors: Duval Jean-François
Published: March 2011

L'exploitation et le travail du fer en forêt de Paimpont existent depuis longtemps - dès l'Antiquité semble-t-il - lorsque apparaît en 1653 le premier haut-fourneau. Toponymie et prospection archéologique témoignent de cette activité dans le cadre de clairières typiques de défrichements médiévaux. À l'origine de cette proto-industrie, des ressources naturelles, minerai et combustible, mais aussi des hommes, les artisans évidemment, et peut-être de puissants laïcs dont la silhouette est néanmoins encore floue.
Les Pays de Lathan. Histoire d'une famille angevine implantée à Saint-Domingue au XVIIIe siècle
Authors: Bonnet Natacha
Published: March 2011

Entre commerce colonial antillais et paysages ruraux de l'Ouest métropolitain, c'est l'histoire d'une famille angevine, bourgeoise et anoblie au XVIIIe siècle ; une famille ayant investi dans la culture de plantation - et tout particulièrement à la « Perle des Antilles », à savoir Saint-Domingue -, mais qui vivait aussi parallèlement en Anjou, au cœur de sa seigneurie baugeoise. Jouant sur les deux tableaux (à la colonie, l'argent de la canne à sucre ; en métropole, celui des fermages) la famille Pays de Lathan a fait de son double cadre de vie un réel atout pour parvenir à égaler l'aisance financière de la haute noblesse, alors qu'elle venait tout juste d'intégrer l'ordre nobiliaire en ce premier tiers du XVIIIe siècle. De plus, en alliant sa destinée avec celle de la vieille noblesse angevine, la dynastie Pays réussit parfaitement, d'une part, à consolider et à étendre géographiquement les limites d'un ensemble seigneurial déjà vaste, et d'autre part, à asseoir les bases de sa prééminence sociale et politique, au sein des sociétés angevine et domingoise.

Toutefois, après l'âge d'or des décennies 1770-1780, la seigneurie de Lathan et les plantations de canne à sucre subirent de plein fouet la tourmente révolutionnaire. Ce ne furent alors que confiscations, dépossessions et quête d'indemnités.
Enterococcus gallinarum meningitis: a case report and literature review
Authors: Khan Fahmi Yousef , Elshafi Sitina Shamsaldin
Published: March 2011

We report a case of Enterococcus gallinarum meningitis in a 53-year-old female who was admitted to our hospital with a fever, headache, and consciousness disturbance one week after a life-saving craniotomy operation. There was obvious neck stiffness; lumber puncture was performed and cerebrospinal fluid parameters were consistent with bacterial meningitis. The patient was given ceftriaxone and vancomycin for bacterial meningitis. Cerebrospinal fluid culture yielded an isolate which was identified as Enterococcus gallinarum. The isolate was sensitive to ampicillin, ampicillin/clavulanate, linezolid, moxifloxacin and teicoplanin, but it showed intermediate sensitivity to vancomycin and quinoprism- dalfopristin. Intravenous linezolid, 600 mg every 12 hours, was started. Three days after starting treatment, the patient became afebrile; a repeat lumber puncture two week later showed no white blood cells in cerebrospinal fluid and no bacterial growth. Treatment with linezolid was continued for a total therapy duration of three weeks, after which the patient was discharged in a good condition.

Published: March 2011

Introduction: Typhoid fever is endemic in many parts of the world and represents a major cause of acute febrile illness (AFI). Rapid and accurate laboratory methods for diagnosis of this disease are needed for both patient care and surveillance situations. Methodology: Serum samples were collected from AFI patients and used to evaluate the performance of a newly developed ELISA assay that uses a mixture of somatic and flagellar antigens to detect the total antibody response against Salmonella enterica subspecies enterica serovar Typhi (S. Typhi) infection. The levels of Ig isotype response (IgG, IgM and IgA) were also evaluated, and results were compared to those of TUBEX-TF and Typhidot commercial kits.  Results: Of 234 culture-confirmed typhoid patients, the total Ig ELISA diagnosed 93% compared to 71% using Widal test. This sensitivity level (93%) is higher than that observed for the individual Ig ELISAs (IgG 75%; IgM 79%; IgA 57%) and the commercial tests TUBEX-TF (75%), Typhidot IgM (63%) and Typhidot IgG (28%). An agreement of 78% was achieved between the total Ig ELISA and Widal test. The average specificity of the ELISA was 96%. Using ELISA, up to 200 samples can be tested per run with cost per test at US$0.20. Conclusions: The developed ELISA shows superior sensitivity and specificity, when compared to Widal, TUBEX-TF and Typhidot assays, is more cost effective and allows higher throughput. This method is highly recommended for active surveillance studies or outbreak investigations of typhoid fever.

Authors: Che Sheng Bing , Luo Jin Kai , Ma Bin
Published: March 2011

A quasi-blind adaptive video watermarking algorithm in uncompressed video wavelet domain based on human visual system is proposed in this paper. This algorithm established a visual model according to the human visual masking and the characteristics of wavelet coefficients. It did not require the scene segmentation of the video, choosing the video frames which used for embedding watermarking by the key, and embedding different watermarking which processed by Arnold scrambling into different frame, so it is robust to statistical analysis, frame crop and so on. To ensure the spatial synchrony when extracting the watermark information, zero-watermarking method and chaotic system are used to generate the synchronization information. The quantized central limit theorem is applied to adjust the low frequency coefficients, it makes the extracted watermark information keeps invariant when its element value changed in robust region. A new correlation detection method of watermarking information was put forward. Watermark detection does not require original video. It realized the quasi-blind watermark detection.

Toughening Study on High Chromium Cast Iron Liner Plates of HZS Series Commercial Concrete Mixing Plant
Authors: Liu Jiang , Fu Jun
Published: March 2011

Because of high wear resistance and low cost, high chromium cast iron liner plate is the most commonly used liner for HZS series concrete mixing station at present. However, in normal operation, the high-chromium cast iron liner produced by conventional casting process is easy to crack at its corners. We found that the cracking reasons of this type of liner plate are mainly the lower cast impact toughness, slightly higher hardness, and there has not gotten a good matching between the hard particles and the matrix organizations. Thus we used the secondary heat treatment to slightly reduce the hardness and increase the impact toughness of cast iron liner plate, which can improve the wear resistance and impact resistance of the liner material to extend the service life of these cast iron liners.

Authors: Jia Qing Ming , Shan Shao Yun , Jiang Li Hong , Wang Ya Ming
Published: March 2011

SiO2 doped by polyaniline for application in electrorheological (ER) ﬂuid was prepared by using a simple one-pot interfacial synthesis method. Scanning electron microscopy (SEM) image shows that the morphologies of SiO2 may be changed from spherical to fibroid structure by changing the molar ratio of tetraethyl orthosilicate(TEOS) and aniline. X-ray diffraction (XRD) proves that polyaniline does not change the crystallinity of SiO2. The ER behaviors of SiO2 doped by polyaniline in silicone oil are investigated with different doping degrees under different shear rate, and the results show that properly doping polyaniline improves electrorheological behavior of SiO2.

Authors: Huang Feng Li , Chen Shui Sheng , Gu Jin Mei
Published: March 2011

An optimization method, integrating correlation degree, response surface method and ant colony algorithm, is proposed for exploring optimal parameters with the molding quality evaluation of warpage amount in injection molding. Initially, a novel formula calculating correlation degree is brought forth on the basis of the definition of distance and place value, and the parameters are chosen using the correlation degree method. Then the approximate model of the injection molding process is constructed by Kriging model with the determined parameters. Finally, the adaptive genetic algorithm and the ant colony algorithm are adopted to solve the optimization problem respectively, and injection molding tests are experimentally performed to validate the optimization results of parameters in injection molding.

Authors: Cai Gang Yi , Huang Xiao Ting , Deng Peng Hui
Published: March 2011

Thermomechanical treatment was adopted to improve the comprehensive performance of AZ80 magnesium alloys in this paper. The influence of varying the thermal processing parameters and deformation on the microstructure and mechanical properties of AZ80 magnesium alloy was studied, and the optimal process of themomechanical treatment was obtained. The experimental results show that the hardness increased with the increasing of deformation and the hardness is up to the peak value with 30% deformation. After aging, the hardness measurements and microstructure analysis results show that the hardness increased with increasing aging temperature, and reached the peak value at temperature 170°C, while the hardness decreased sharply when the temperature goes beyond 170°C. After thermomechanical treatment, the grains of AZ80 magnesium alloy became uniform and fine. The roles of both deformation strengthening and dispersion strengthening were to improve the mechanical property of AZ80 magnesium alloy.
