“Gestuologie” et littérature: L’Éxemple de Balzac
Authors: Bui Véronique
Published: October 2010

La “gestuologie” se donne pour objet de déceler l’écart entre ce que disent les hommes et ce qu’ils montrent. La Comédie humaine , par son titre même, indique que cet écart sera mis à nu par l’écrivain. Mais le projet de révéler l’homme social et le mensonge social en s’appuyant sur ce que les sciences peuvent apporter comme base et comme méthode ne date pas de 1842. Dès 1833, dans La Théorie de la démarche , Balzac expose cette ambition de conjuguer observation scientifique et art de la narration. Mais si le théoricien de 1833 échoue à classifier les hommes en fonction de leur démarche, en revanche, le futur auteur de La Comédie humaine entrevoit le profit littéraire qu’il va pouvoir tirer de cette démarche, une démarche nouvelle, axée résolument sur l’homme et sur ce qu’il dévoile, et dont il livre les fondements de la théorie.

Writing Against Theodicy: Reflections on the Co-Existence of God and Evil in Baudelaire’s Poetry and Critical Essays
Authors: Powers Scott M.
Published: October 2010

This article uncovers a sustained reflection in Baudelaire’s writings on the coexistence of God and evil. In the 1857 and 1861 editions of Les Fleurs du Mal , there is already a movement away from the divine in poems that depict evil as a more compelling concept and as the dominant force. In his critical writings and prose poems, Baudelaire increasingly engages in questions of theodicy to suggest the incompatibility of God and evil. This article describes an overarching system of writing “against theodicy” that links Baudelaire’s book reviews, art criticism, and essays on child psychology and psychedelic drugs, and that provides a conceptual framework for the shift in his poetics from romanticism to realism. As a textual analysis of these works demonstrates, Baudelaire’s writing “against theodicy” repeatedly leads his readers to draw the conclusion of God’s nonexistence in the face of the reality of evil.

Allegory and Exoticism: Balzac’s Allusion to La Liberté guidant le peuple in La Fille aux yeux d’or
Authors: Linton Anne
Published: October 2010

In this article, I argue that an allusion to Delacroix’s La Liberté guidant le peuple (1830) has been overlooked in Balzac’s short novel, La Fille aux yeux d’or (1834–1835) as the marquise stands bare-breasted over a dying woman. Whether or not Balzac’s reference is intentional, the chronology of events and Balzac’s admiration of Delacroix make such an allusion possible, while key visual and thematic elements further link the two representations. Balzac’s use of allegory in La Fille aux yeux d’or rehearses Delacroix’s highly controversial portrayal of Liberté as a sexualized, corporeal woman rather than a lofty, aesthetic ideal. Balzac uses this image, I argue, as a means to further criticize the rampant materialism of the July Monarchy even though the main action of the novel takes place during the Hundred Days. ( al)
The Politics of Authorship: The Effects of Literary Property Law on Author-Publisher Relations
Authors: Haynes Christine
Published: October 2010

This article argues that the shift in author-publisher relations over the course of the nineteenth century, which has been characterized by scholars as alternatively either a “consecration” or a “degradation” of the author, was connected to a change in the law on literary property. Through a comparison of the terms of letters and contracts between authors and publishers before and after a landmark law of 1866, which extended literary property to 50 years after the death of the author, it shows that the new law favored publishers, by enabling them to monopolize and control the work of authors to an unprecedented extent.

Flaubert: Remembering, Forgetting, Creating
Authors: Green Anne
Published: October 2010

Curiously tormented references to memory abound in Flaubert’s work. Examples from Novembre , Madame Bovary , Salammbô , L’Éducation sentimentale , Trois contes , Bouvard et Pécuchet and Sous Napoléon iii reveal a recurrent pattern of memory description that is echoed in the Correspondance . Recurrent images of being invaded, crushed, stifled or drowned by memories combine with images of liquidity, bloodshed and death. Yet the same terms and images recur in Flaubert’s accounts of the painful creative process, and clusters of such images in his fiction point to a subtext about the agonies of writing: memory was an essential component of the struggle to create.

Les Trois Romans expérimentaux d’Émile Zola: Lourdes , Rome , et Paris
Authors: Cook-Gailloud Kristin
Published: October 2010

The ideas developed by Émile Zola in the Experimental Novel ( Le Roman expérimental ), published in 1880, were not fully put into effect until he wrote a trilogy of novels entitled the Three Cities ( Lourdes , Rome , and Paris , published between 1894 and 1898). Written against the backdrop of a heated struggle between science and religion, these novels are clearly structured as a triple scientific experiment with a hypothesis, independent and dependent variables, a procedure, a result and a conclusion, while aiming to prove that Catholicism has become an outdated and hence nefarious theory. By applying Claude Bernard’s experimental method to these novels, Zola lays the foundations for a new paradigm of thought which he fully discloses in his last work, The Four Gospels : a literary prophecy that recasts the principles of the New Testament in order to develop a cognitive tool for conceptualizing the happiness of mankind.

Isaac Louverture’s Mémoires : A Nineteenth-Century Representation of Black Masculinity in the Name of the Father
Authors: Saint-Aubin Arthur F.
Published: October 2010

Isaac Louverture’s 1818 memoir, when read in tandem with the memoir (1802) of his father, Toussaint Louverture, offers a nuanced representation of black masculine subjectivity and agency—one that elegizes his father’s legacy while simultaneously rewriting an episode from his father’s narrative. Within the context of the events in Saint-Domingue prior to independence, the son’s memoir suggests the possibility of a different dynamic between black and white men in part by calling into question his father’s account of the latter’s relationship to Napoleon and Saint-Domingue’s relation to France.

When Tests ‘Frame’ Children: The Challenges of Providing Appropriate Education for Children With Special Needs
Authors: Galletly Susan A. , Knight Bruce Allen , Dekkers John
Published: October 2010

Decision-making regarding intensive instructional support for children with special needs should build from children's instructional needs, and not from diagnostic labelling and criteria for funding eligibility. Cognitive referencing, the use of results on intelligence and language quotients to decide children's academic options and funding eligibility, is established as inappropriate practice yet continues to be used by many education systems. This paper discusses systemic practices in Australia, the United Kingdom and the United States, and then details four cases of children ‘framed’ by their tests, that is, experiencing unwarranted disadvantage due to how they were positioned by their tests and diagnoses. The final section makes recommendations for considerations needed in the improving of Australian education of children with special needs.

Os acidentes de transporte terrestre (ATT) causam expressivo número de mortes e hospitalizações entre jovens no mundo, sendo no Brasil responsável por 17,1% dos óbitos entre 10 e 14 anos. Este artigo apresenta resultados da Pesquisa Nacional de Saúde do Escolar (PeNSE), inquérito realizado em uma amostra probabilística de escolares do 9º ano do ensino fundamental de escolas públicas e privadas das capitais brasileiras, em 2009. Foram estimadas as prevalências (e IC95%) das situações de risco para acidentes de transporte. Os 60.973 entrevistados indicam que (nos últimos trinta dias): 26,3% (IC95% 25,5%-27,0%) referiram nunca ter usado cinto de segurança; 18,5% (IC95% 18,0%-19,1%) dos menores de 18 anos referiram ter dirigido veículo motorizado (>1 vez); 18,7% (IC95% 18,1%-19,2%) referiram ter sido transportados em veículo conduzido por alguém que consumiu bebida alcoólica (>1 vez) e 35% (IC95% 33,8%-36,2%) referiram não ter usado capacete pelo menos uma vez quando andava de motocicleta. Os resultados estão de acordo com as elevadas taxas de morbimortalidade de jovens no país por ATT, o que reforça a importância de ações educativas para adolescentes e a necessidade de ações intersetoriais integradas, além de legislação específica e fiscalização rigorosa.
Saúde da família e cuidados paliativos infantis: ouvindo os familiares de crianças dependentes de tecnologia
Authors: Rabello Claudia Azevedo Ferreira Guimarães , Rodrigues Paulo Henrique de Almeida
Published: October 2010

O estudo discute um modelo de cuidados paliativos infantis baseado na Saúde da Família quando da assistência domiciliar, articulado com os demais níveis de atenção e nas demandas das famílias. Participaram do estudo dezoito membros de nove famílias de crianças do Instituto Fernandes Figueira (IFF), das quais quatro estão assistidas pelo Programa de Assistência Domiciliar Interdisciplinar (PADI), três internadas aguardando a inclusão no programa e duas internadas e já pertencentes ao PADI. O PADI foi estudado por ser o único que oferece cuidados paliativos infantis na rede pública de saúde. Os resultados demonstram-se positivos quanto ao vínculo estabelecido com a equipe, ao acolhimento, ao conhecimento pelos familiares acerca da doença e à dinâmica entre o PADI e o IFF. Como pontos negativos aparecem as dificuldades, que vão desde a implantação do programa até sua continuidade; quase todos os familiares referem agravos ou doenças. Concluiu-se, que apesar de o PADI se apresentar como a forma encontrada pelo IFF para a desospitalização, os cuidados domiciliares pela Saúde da Família, bem articulado com a rede, seriam o ideal por se tratar do nível de assistência adequado para tal.
The influence of ageing on the morphological and optical properties of thin TPD films
Authors: Trifunovic Sasa , Milicevic Dejan , Micic Maja , Mudrinic Tihana , Suljovrujic Edin
Published: October 2010

This paper presents the influence of ageing on the morphological and optical
properties of TPD (N, N? - Bis (3 - methylphenil) - N, N? diphenylbenzidine)
thin films. Understanding of the nucleation mechanism and growth dynamics of
molecular thin films is pivotal for controlling their morphology and the film
interfacial properties, while the influence of ageing is essential for the
potential commercial utilization. Initially, thin films were prepared using a
combinatorial physical vapour deposition (CPVD) method, following a
cosine-like distribution profile of thickness along monocrystal silica
substrate. Morphology of thin films was investigated by using optical (OM)
and atomic force microscopy (AFM). The link between optical properties and
the resulting thin film morphology was made by spatially correlated
morphological (AFM and OM) and optical (absorption and photoluminescence)
measurements. The changes in the absorption and photoluminescence spectra are
strongly connected to the ageing-induced changes in the microstructure of
thin films. Regardless of morphological and differences in the film thickness
(two orders of magnitude), all films show amorphous arrangement just after
the deposition. Ageing of these films in regular atmosphere conditions
results in morphological and changes in optical properties induced by the
crystallization. The crystallization of initially amorphous samples was also
confirmed by the differentional scanning calorimetry (DSC) measurements. All
results indicate the limited possibility of using TPD films in organic
electroluminescent devices.
Characteristics and composition of melon seed oil
Authors: Milovanovic Mirjana , Picuric-Jovanovic Ksenija
Published: October 2010

Dried melon seeds (Citrullus colocynthis L) of the family Cucurbitaceae were investigated for nutritional quality and the oil seed characteristics. These melon seeds, on a dry weight basis, consisted of 52.3% of test and 47.7% of kernel. The moisture content in melon seeds was 54.5% and the mineral constituents were also determined. The oil content of seeds was very high ranging from 22.1-53.5%, due to the presence of the hulls, 22% from the seeds and 53% of the kernel, and also the crude protein content was so high as the 21.8% of the seeds. Standard procedures were applied to determine the fatty acids composition of the seed oil. The fatty acid profiles of the seed oil showed an unsaturated fatty acid content of 77.4% and the high content of 63.2% of PUFA. The predominant fatty acid was linoleic (18:2) acid in 62.2%. The presence of other fatty acids ranged in 10-14% for oleic (18:1) stearic (18:0) and palmitic (16:0) acids, respectively. Furthermore, the physical and chemical characteristics of the seed oil was also determined as iodine, acid, saponification, peroxide values and specific gravity.
Correlations of yield and grain yield components of winter wheat varieties
Authors: Protic Rade , Todorovic Goran , Protic Nada
Published: October 2010

Mean positive correlation (r = 0,47**) between grain yield and number of plants per m? and strong correlation between grain yield and number of spikes per m? were established (r = 0,55**). Weak correlation was established between grain yield and productive tillering (r = 0,24**). Strong positive correlation (r = 0,51**) is between the number of spikes per m? and productive tillering, as well as between the number of plants per m? and number of spikes per m? (r = 0,68**). Very weak negative correlation (r = -0,12*) is between productive tillering and the number of plants per m?. Regression equations of grain yield and other investigated traits, on the level of significance 5% and 1%, have linear form. By increasing one plant per m?, the number of spikes for one per m?, productive tillering for one, grain yield will be increased for 0,006 t/ha, 0,005 t/ha and 1,174 t/ha on the average. The other regression equations between the number of spikes per m?, number of plants per m? and productive tillering have linear form. By increasing one plant per m? and productive tillering for one, the increase of number of spikes per m? is 1,087 and 312,21 on the average. By increasing the number of plants per m?, productive tillering is reduced for 47,59 on the average.
Internationalization of the competition law
Authors: Scepanovic Nina
Published: October 2010

In the present stage of development of international economic relations multilateral regulation of competition is becoming more and more important in order to, firstly, annul the effects of domestic rules of competition that are today considered the greatest non-tariff limitation, secondly avoid conflicts that can be caused by exterritorial implementation of national rules in this field, and, finally, define the rules of behavior in the world market. Although the first attempts to regulate this field were made pretty long ago and some activities were taken within UNCTAD, OECD and GATT, no comprehensive rules considering the issues they define and a group of countries that implement them have been adopted at the international level, so far. For the time being, numerous competition problems in relations among countries have been overcome by concluding a number of bilateral agreements and several regional arrangements.

Behavioural response of moose Alces alces and brown bears Ursus arctos to direct helicopter approach by researchers
Authors: St⊘en Ole‐G. , Neumann Wiebke , Ericsson Göran , Swenson Jon E. , Dettki Holger , Kindberg Jonas , Nellemann Christian
Published: October 2010

Helicopters are used for numerous wildlife management and research purposes, but can alter wildlife behaviour and influence baseline data collection. We investigated reactions of GPS‐collared moose Alces alces and brown bears Ursus arctos to short‐term helicopter approaches by researchers. Moose responded with up to 10 times greater movement rates for up to two hours following a helicopter approach and moved into more rugged terrain. Brown bears decreased their speed and remained within similar habitat types and terrain. The movements were influenced only about two hours and did not influence the size of the activity areas. Contrary to our predictions, brown bears responded with a somewhat calmer response than moose, illustrating response differences in large herbivores and carnivores. This difference in response might be because brown bears are actually less disturbed than moose by direct helicopter approaches or because of a difference in tactical behaviour between brown bears and moose following disturbance. Researchers and managers should thus be cautious in using knowledge from one species to predict or perceive disturbance response in another species or taxa.
The Boomerangs Parenting Program for Aboriginal Parents and Their Young Children
Authors: Lee Lily , Griffiths Chryne , Glossop Patricia , Eapen Valsamma
Published: October 2010

Objective: Using three case studies, this paper describes the development and evaluation of ‘The Boomerangs Aboriginal Circle of Security Parenting Camp Program', which is a clinical intervention based on an attachment framework using the Circle of Security and Marte Meo, and drawing on traditional Aboriginal culture.

Methods: Three mothers from an Aboriginal Australian background with preschool age children attended the 20-session Boomerangs Program, including an initial camp and a second camp after 6 weeks. The camp provided the opportunity for parent empowerment and to explore the strengths and resources of the mother to facilitate better mother-child interactions and relationship, in a naturalistic setting.

Results: All three mothers gave positive feedback on the program in increasing the awareness, sensitivity and responsiveness of their interactions with their children, and this was reflected in the results of the questionnaires and observation of the mother-child interactions during play.

Conclusion: This program offers the first ever evaluation of an intense parenting program using camps for Aboriginal Australians. This study is to be considered as an exploratory exercise – a first step in a process of exploring applicability and adapting parenting camps for Aboriginal families.
La bilingualité des enfants de migrants face aux enjeux de la transmission familiale
Authors: Bensekhar-Bennabi Malika
Published: October 2010

Résumé Une approche du bilinguisme précoce, inscrite dans le champ de la clinique transculturelle, nous révèle que l’idée selon laquelle les enfants d’étrangers ont deux langues n’est pas toujours exacte. La référence à un jeu complexe de facteurs que nous situons à un point de croisement entre deux axes, l’un correspondant à la projection identitaire des parents et aux mouvements d’affiliation des enfants, l’autre correspondant à l’attachement aux langues du côté des parents et au positionnement par rapport à elles du côté des enfants, peut permettre de comprendre cette difficulté de transmission des langues.
L'entre-jeu
Authors: Martagex France
Published: October 2010

Résumé La surdité convoque avec force la question du langage. Le récit de trois rencontres met en perspective de façon singulière la réalité d’une langue qui défaille, à partir d’un accompagnement éducatif spécifique au sein d’un cmp. Ces parcours thérapeutiques éclairent comment des mouvements peuvent s’inscrire dans un espace de médiation, en amenant parfois des êtres ou des relations en rupture jusqu’à un point de bascule. Ce phénomène intervient dans le processus thérapeutique à l’endroit même où surgit une langue pour se dire ; qu’il s’agisse de sons ou de signes, émergent alors un sens et une enveloppe donnant vie au désir de se relier.
Le genre et le leadership
Authors: Saint-Michel Sarah
Published: October 2010

Les entreprises françaises se trouvent confrontées à un problème de représentation équilibrée des hommes et des femmes aux postes de direction et de pouvoir. Face au phénomène du plafond de verre , les femmes restent sous représentées dans les positions de pouvoir et de direction. Pour expliquer en partie ce phénomène, certains chercheurs mettent en avant le poids des stéréotypes en terme de genre et du « modèle managérial dominant » qui entraveraient l’accès des femmes à ces positions de pouvoir et de leadership. Ainsi le genre semble être une variable importante qui structure les organisations et, il nous paraît important de l’introduire, afin d’expliquer et de comprendre l’impact éventuel du genre sur le style de leadership. De plus, face à l’intérêt grandissant des recherches sur les différences individuelles et le leadership par le biais du modèle du « Big Five » (Costa et McCrae, 1992), il nous paraît important de comprendre et d’expliquer l’impact du genre sur les traits de personnalité des leaders. Cette communication tente de dresser un état des lieux de la recherche théorique et empirique des liens entre le genre, le leadership et les traits de personnalité du leader.
La satisfaction au travail
Authors: Iglesias Katia , Renaud Olivier , Tschan Franziska
Published: October 2010

La satisfaction au travail est un concept central en gestion des ressources humaines. Malgré cela les relations trouvées entre ce concept et d’autres variables du champ restent encore parfois incertaines voire même contradictoires dans certains cas. Cet article relève trois problèmes : le premier, pouvant affecter directement les liens entre la satisfaction au travail et d’autres variables du champ, concerne les outils statistiques utilisés pour analyser la satisfaction au travail. Pour discuter de ce point, nous évaluons les besoins des chercheurs pour répondre à leurs questionnements, ainsi que les apports et limitations des différents outils statistiques utilisés. Les deuxièmes et troisièmes problèmes touchent la satisfaction au travail elle-même et concernent la définition ainsi que les instruments de mesure de la satisfaction au travail. Une fois ces problèmes énoncés, sur la base d’un jeu de données empiriques et en utilisant les outils statistiques adaptés pour répondre aux questions des chercheurs, nous avons analysé quatre mesures de satisfaction au travail avec des modèles à effets mixtes. Pour analyser ces dernières, deux groupes de déterminants ont été utilisés : des facteurs liés au travail et des facteurs liés à la personne. Il ressort que pour les déterminants fortement liés à la satisfaction au travail, les résultats sont proches pour les quatre échelles de satisfaction au travail. Par contre, pour les variables explicatives dont le lien avec la satisfaction au travail est plus faible, la significativité va dépendre du choix de l’instrument de mesure de la satisfaction au travail. Par conséquent, les différentes échelles de satisfaction au travail analysées n’opérationnalisent pas la même définition de la satisfaction au travail.
La capoeira : ni lutte, ni danse. Proposition de définition
Authors: Meziani Martial
Published: October 2010

Résumé Le présent travail se propose de définir la capoeira sous un nouvel angle. Habituellement considérée comme un mélange de danse, de lutte, de rituel et de bien d’autres disciplines ou activités, nous avançons le postulat qu’il s’agit d’une activité dont la cohérence est propre à toutes les academias . Nous proposons pour ceci d’utiliser le concept de jeu paradoxal, de P. Parlebas. Cette réflexion s’appuie sur un terrain ethnographique de sept ans dans une académie parisienne, ainsi que de visites d’académies en France et au Brésil. Il s’agira pour nous de montrer en quoi la capoeira est bien une activité motrice à part, dont les structures n’ont pas été pensées jusque-là par le langage de la société dominante.

Éclipses : propagande et utopie
Authors: de Sousa Edson Luiz André
Published: October 2010

Aborder le thème de la propagande devient de plus en plus essentiel, car nous ne pouvons pas penser la propagande sans transiter par les circuits du pouvoir que nous constituons et qui nous constituent. Mais de quel pouvoir s’agit-il ici ? Pouvoir de l’image, dans la mesure où elle tente de capturer le regard de l’autre à un point précis, en fixant le sens de manière arbitraire, en laissant dans l’ombre tout ce qui serait susceptible de provoquer une crise d’interprétation et de lecture. L’objet doit se révéler de façon univoque, et ce détail suffit pour percevoir la tyrannie de cette position. Le développement des idées présentes dans ce travail se base sur le fonctionnement de la machinerie de la propagande dans le champ de la politique proposé par Noam Chomsky, ainsi que sur les contributions importantes de Sophie de Mijolla-Mellor issues du champ conceptuel de la psychanalyse.
Le film de fiction comme instrument de propagande : le cas Tropa de elite
Authors: Bergami G. Barbosa Pablo
Published: October 2010

Pour comprendre l’utilisation des films de fiction comme instruments de propagande le présent article rattache cette dernière aux thèses freudiennes sur la psychologie des foules, la culture et la société. À partir de cette confrontation, la propagande se caractérise comme une arme de la culture pour contrer le malaise dont elle est productrice. Ensuite, l’analyse du film brésilien Tropa de elite sert à voir concrètement comment le scénario fantasmatique latent en son rapport avec le contexte social et idéologique peut rendre un film de fiction effectif en tant que propagande. L’univocité du point de vue constitué par le film étant le trait qui permet de l’appréhender comme de la propagande même s’il n’a pas été conçu comme tel.
Parole d'argent et emprunt or
Authors: Baubeau Patrice
Published: October 2010

Résumé Antoine Pinay a rénové, entre 1952 et les années 1960, le mythe du sauveur du franc tel qu’il avait été incarné par Raymond Poincaré après 1926. Or loin d’être la seule conséquence de ses compétences et du succès de son action gouvernementale, cette captation de l’image poincariste découle d’abord de l’instrumentalisation de son identité politique par Pinay. En effet, situé par sa culture politique parmi les héritiers potentiels de Poincaré, il profite de l’horizon d’attente créé par la crise du franc de 1951-1952 pour forger une image publique qui reflète sa « politique de confiance ». Traits biographiques et idéologiques sont ainsi mis au service d’un positionnement politique qui témoigne de la plasticité d’une culture politique, comme ensemble de ressources à mobiliser, et de son utilité pour signifier, au-delà des mots, les référents idéologiques mobilisés, complétant l’action technique par une politique visant l’adhésion de l’électorat.
Remelting Technology and Microstructural Evolution of Semi-Solid Al-7Si-2RE Alloy
Authors: Xie Shi Kun , Yi Rong Xi , Guo Xiu Yan , Pan Xiao Liang , Zheng Xiao Qiu
Published: October 2010

In semi-solid remelting process, the various stages of reheating temperature and isothermal holding time must be accurately controlled in order to obtain the uniformly distributed and small equiaxed grains microstructure. In this paper, a temperature control program was developed and the remelting process for Al-7Si-2RE aluminum alloy was carried out. The results showed that with the raise of reheating temperature and the extension of isothermal holding time, the liquid fraction increases, α-phase grain grows and becomes rounding in the process of Al-7Si-2RE alloy semi-solid remelting. The most reasonable process parameter of reheating temperature is at 585~590°C and its appropriate isothermal holding time are about 10~15min for the semi-solid Al-7Si-2RE alloy.
P-CMAC-Based Control Method and its Application in Filament Tension Control
Authors: Chen D.X. , Wang G.
Published: October 2010

Cerebella Model Articulation Controller (CMAC) is considered as local association and generalization neural network. Parametric CMAC (P-CMAC) is a modification to the original CMAC. The introduction of continuous activation function applied in the input space can overcome the binary behavior of the original CMAC. Takagi-Sugeno(TS) type fuzzy inference is embedded in the internal mapping to improve the approximation accuracy. Hybrid control scheme, which combines P-CMAC neural network and traditional PID controller, is proposed in the paper. The output of P-CMAC network dominates the overall control signal applied to the plant, while the traditional PID controller serves as compensator for reducing tracking error. The application of hybrid control scheme to filament tension control is illustrated. The experimental results have shown the effectiveness and accuracy improvement of the control scheme.
Effects of Ultrasonic and Mechanical Stirring on Microstructures and Properties of Nano-Composites
Authors: Xu R.D. , Wang Jun Li , Zhang Y.Z.
Published: October 2010

Ni-W-P/CeO2-SiO2 nano-composites were prepared on carbon steel surface by pulse co-deposition of Ni, W, P, CeO2 and SiO2 nano-particles. The influence of ultrasonic time and mechanical stirring on microstructures and properties were researched, and the characteristics were assessed by chemical compositions, element distribution, deposition rate, microhardness and microstructures. The results indicate that the nano-composites possess compact microstructures, clear outline of spherical matrix metal crystallite, fine crystal size, and uniform distribution of nano-particles within Ni-W-P matrix metal when treated by ultrasonic of 30mins and mechanical stirring of 1000rpm. An increase of the mechanical stirring velocity leads to refinement in grain structure and the corresponding increase of the deposition rate and the microhardness.

Manufacture and Characteristics of Fibrous Composite Z-Pins
Authors: Wang Xu Xu , Chen Li
Published: October 2010

Z-pins are thin fibrous composite or metallic rods that could increase the strength of laminated composites in the thickness direction. In this paper, three kinds of composite z-pins were made by improved pultrusion method. The length of pultrusion die is shortened to 30mm with no function of curing. The curing equipment is individual control drying ovens. And then, tensile properties of z-pins were reported as well as the appearance and fiber content. Results show that three kinds of z-pins have good flexural resilience. The fiber volume fraction is around 60%. Carbon fiber z-pin has smoother surface than aramid fiber z-pin. And, The thinner z-pin corresponds to the higher tensile strength and tensile modulus. The elongation rate of aramid fiber z-pin is greater than that of carbon fiber one.
Numerical Study on Shock Wave Propagation with Obstacles during Methane Explosion
Authors: Qu Zhi Ming
Published: October 2010

During shock wave propagation in the pipeline, the flow field of speed, pressure and temperature is evenly distributed. If there are obstacles, then the flow will be changed while the velocity gradient is formed near the obstacles. Passing through the obstacles, a high-speed gradient of the unburned methane mixture flow is established. While reaching the obstacle, the shock wave surface is rapidly stretched to increase the significant transmission speed. Propagating in the gradient field, the shock wave will be stretched and folded. The deformation of shock wave causes consumption of fuel and oxygen in greater unburned methane surface, which results in heat release rate increasing and faster shock propagation. In conclusion, shock wave causes larger advection speed in front of the unburned methane mixture, increasing flow velocity gradient further and leading to more intense shock wave propagation.
Experimental Researches on Temperature-Dependent Tensile Properties of Laminated Resin Composites Reinforced by Plain Woven Fabric
Authors: Chen Guang Wei , Li Jia Lu , He G.F.
Published: October 2010

The purpose of this paper is to investigate the tensile property of laminated resin composites reinforced by carbon fiber plain woven fabric at relatively high temperature. For this purpose, the tensile tests of laminated resin composites are carried out at room temperature(20°C) and high temperature(150°C and 180°C). The effect rules of different temperature on the tensile property of these composites are discussed. The reasons for the variations of tensile property of these composites at different temperature are also analyzed. At 150 °C and 180 °C, the tensile strength of laminated composite decreased by 13.3% and 34.42% respectively, compared with that at room temperature, which shows that the tensile strength of resin laminated composites is sensitive at high temperature. The reason of the tensile strength of resin laminated composites declined at high temperature is that resin has been damaged and can not transfer tensile load, which makes resin and fiber can not bear the tensile load together at high temperature. The research results will provide a basic reference for the application of plain woven fabric reinforced resin laminated composites at room temperature to 180°C.

Authors: Zhou Ming , Jia P.
Published: October 2010

The development of the ability to machine glass materials to optical tolerances is highly desirable. The machinability of glass is poor in diamond cutting due to the high hardness and the high brittleness of glass. In order to investigate the effects of cutting fluids on the machinability of glass, this paper selected boric acid solution and sodium carbonate solution as cutting fluids, and then scratching tests were carried out. The resulting scratches with and without cutting fluids was assessed based on the observations of the micro-morphology of the scratched grooves utilizing confocal microscope. Experimental results indicated that compared with the process without cutting fluids action, the machinability of glass BK7 can be improved by using boric acid solution or sodium carbonate solution as the cutting fluids.

Authors: Wang Jun Li , Shi Qing Nan
Published: October 2010

Ultra-Fine-Grained (UFG) copper strip was prepared by severe deformation method of asymmetrical accumulative rolling bond (SD-AARB) with heat treatment, in which the reduction rate of 1.08 was employed with 50% rolling reduction by six passes(4.8 true strains). The heat treatment was conducted at annealing temperature of 220°C for 5~55 minutes. EBSD and X-ray diffraction were employed to follow the features of texture and orientations. The texture formulation mechanism of deformed copper recrystallized nucleation was studied. The results show that the deformation textures developed in the copper strip by SD-AARB are very similar to those by common the cold rolling process, which is {112}<111>. After the annealing treatment, the strength of the main texture components in the oxygen-free pure copper is decreased along with the extension of recrystallization annealing time, which is C,R,S and B/G texture components. For high energy release rate, grains of all kinds of orientations have the chance of nucleation and growing up, which is different to traditional recrystallized cube texture.
