Effects of Titanium Oxide Precipitates on the Acicular Ferrite Nucleation in Carbon Structural Steel
Authors: Hui Kong , YunFu Shen , YaHui Zhou , Qiang Yue , Lianhai Tong , ZhengYu Cai
Published: February 2014

The features of inclusions and microstructure for Ti-added carbon structural steel (C: 0.26 wt.-%) were studied by scanning electron microscope (SEM) and energy dispersive spectrometer (EDS). After etching, it has been found that the titanium oxide can act as nucleation site for acicular ferrite. Moreover, from the SEM-EDS mapping images, it can be seen that the MnO-SiO2 phase occupies the core of nucleation inclusion, and the titanium oxide precipitates on them. This result can be explained by theoretical calculation, and this kind of precipitation does not lead to inclusion coarsening. Furthermore, the element sulfur accumulates on the periphery of nucleation oxides, which implies the absorption of MnS plays an important role for the acicular ferrite formation. These results confirm that titanium oxide precipitate can also induce the acicular ferrite formation, and may gain new insights in the oxide metallurgy.
From Hazardous Red Mud Waste to Non-Hazardous Commercial Products
Authors: Kilic Yasemin , Günay Esin , Marsoglu Müzeyyen
Published: February 2014

Red mud is a waste generated by the aluminium industry and its disposal is a major problem. Red mud waste from Eti Seydişehir aluminium plant of Turkey was considered as a hazardous waste for the environment and human health. The storage of the red mud is difficult due to its high amount of various metal oxides, elements and caustic content. In this study, the environmental compliance tests of the produced construction products of red mud were done and evaluated according to the >Regulation on Regularly Storage of Waste in Turkey<. According to the test results red mud, a hazardous waste alone, can be used in the construction products production. The construction products produced with red mud do not contain hazardous substances and thus, fit the requirements of the >Regulation on Regularly Storage of Waste in Turkey<.
Desire and Ethics
Authors: Buchanan Ian
Published: February 2014

This paper argues that it is problematic for the future of Deleuze studies that it is difficult if not impossible to answer the question ‘what is the right thing to do?’ from a Deleuzian perspective. It then argues that one of the key reasons Deleuze studies has made limited progress in this area is its over-emphasis on desire and the corresponding tendency to extrapolate ‘ought’ from ‘is’, which as Hume showed is a category mistake. It proposes that to develop a workable ethical discourse from Deleuze's work we need to rethink how we read his work and approach it afresh.
What is Pharmacoanalysis?
Authors: Lambert Gregg
Published: February 2014

In A Thousand Plateaus, Deleuze and Guattari call for what they term a ‘pharmacoanalysis’ as an ancillary, but nevertheless related, component of schizoanalysis. Employing Spinoza's theory of affections, they argue that if desire is only the conscious idea of the effect of an external body on our own, then especially around the question of drugs psychoanalysis fails to provide an adequate idea of the real effective bodies that act on our bodies and our minds. Instead, it conceals these real and effective bodies behind a symbolic form that organises our ideas according to a consistent pattern of signification. In the case of certain drugs, moreover, desire bypasses a symbolic order and directly invests the perception and the perceived. A pharmacological investigation reveals real social and political consequences in that molecules, like individuals, are organised into living societies, and the drug can enter into one society in order to effect a change in composition, either by adding new relations or causing existing relations to decompose. This insight is then applied to the threefold illusion of consciousness, producing a more accurate analysis of the problem of addiction and a critique of the moral prohibition that usually determines the representation of illicit drugs, and at the same time, the ‘Oedipalisation’ of certain other drugs prescribed by the legal dealer, or clinical physician.
Flow, Code and Stock: A Note on Deleuze's Political Philosophy
Authors: Smith Daniel W.
Published: February 2014

In Anti-Oedipus, Deleuze and Guattari claim that a general theory of society must be a generalised theory of flows. This is hardly a straightforward claim, and this paper attempts to examine the grounds for it. Why should socio-political theory be based on a theory of flows rather than, say, a theory of the social contract, or a theory of the State, or the questions of legitimation or revolution, or numerous other possible candidates? The concept of flow (and the related notions of code and stock), I argue, is derived from contemporary economic theory, and most notably John Maynard Keynes. Deleuze and Guattari remained Marxists, not only because they held that contemporary political philosophy must inevitably be centred on the analysis of capitalism, but also because they held, following Marx himself, that the Marxist analysis of capital must constantly be transformed and adapted to new conditions. Thus, while certain aspects of Marx's analysis disappear from Capitalism and Schizophrenia, they are supplemented by the addition of new concepts adequate to the contemporary state of capitalism. The paper concludes, then, with an analysis of the role played by the concepts of flow, code and stock in Deleuze and Guattari's political philosophy.
Deleuze and Guattari and the Future of Politics: Science Fiction, Protocols and the People to Come
Authors: Bogue Ronald
Published: February 2014

When is the future? Is it to come or is it already here? This question serves as the frame for three further questions: why is utopia a bad concept and in what way is fabulation its superior counterpart? If the object of fabulation is the creation of a people to come, how do we get from the present to the future? And what is a people to come? The answers are (1) that the future is both now and to come, now as the becoming-revolutionary of our present and to come as the goal of our becoming; (2) utopia is a bad concept because it posits a pre-formed blueprint of the future, whereas a genuinely creative future has no predetermined shape and fabulation is the means whereby a creative future may be generated; (3) the movement from the revolutionary present toward a people to come proceeds via the protocol, which provides reference points for an experiment which exceeds our capacities to foresee; (4) a people to come is a collectivity that reconfigures group relations in a polity superior to the present, but it is not a utopian collectivity without differences, conflicts and political issues. Science fiction formulates protocols of the politics of a people to come, and Octavia Butler's science fiction is especially valuable in disclosing the relationship between fabulation and the invention of a people to come.
Flashforward: The Future is Now
Authors: Pisters Patricia
Published: February 2014

In The Future of the Image (2007) Jacques Rancière states that the end of images is behind us. He argues for an aesthetics of the image that acknowledges the continuing power of images as educating documentations of traces of history, as directly affecting interruptions, and as open-to-combining signs of the visible and the sayable ad infinitum. But does Rancière's claim also concern the future of cinema? His cinematic references, in a Deleuzian sense, are mostly to modern time-images. Is the future of film indeed a form of the time-image, or has the ‘heart’ of cinema moved beyond this image-type? This paper proposes to look at a third category of cinematographic images, based in the third synthesis of time as developed by Deleuze in Difference and Repetition. This filmic image, that could be called the neuro-image, is connected to the impure regime of images typical for the database logic of the digital age. By comparing Alain Resnais's Hiroshima Mon Amour (1959) to the television series FlashForward (2009) , I will analyse the temporal operations of the image of the time-image to these images of a new regime of images, the image of and from the future.1
A Criminal Intrigue: An Interview with Jean-Clet Martin
Authors: Boundas Constantin V.
Published: February 2014

With Jean-Clet Martin's book, Une intrigue criminelle de la philosophie: lire la Phénoménologie de l'Esprit de Hegel, the latter emerges as a philosopher of (negative) difference and (infinite) repetition, one of the first to inject Being with becoming, in other words, as the brother-enemy that Deleuze had been waiting for and with whom he did establish complex relationships that cannot be conveniently summarized in his Nietzschean moment. In view of his novel and striking reading of Hegel, Martin is invited by the interviewer to defend his suggestions that the negative and the dialectic need not turn into spoilers of the joys of Spinoza and the affirmations of Nietzsche; that Hegel's anti-humanism can be counted as a variation on Deleuze's own; that Hegel did anticipate Deleuze in the distinction between becoming and history and in the separation of the virtual event from the actual state of affairs; that Hegel's death of God ushers in, ahead of Nietzsche's Zarathustra, the death of man in the ‘overman’; and that, despite their infinite proximity, Hegel and Deleuze are separated by two incompatible images of thought that make the difference between them a difference of nature and not only a difference of degree.
Converging Ideologies in William Fowler’s Hybrid Translation of Machiavelli’s Il Principe
Authors: Mainer Sergi
Published: February 2014

This article explores the place of William Fowler’s translation of Machiavelli’s Prince in the Scottish Jacobean polysystem. Even if it was never finished, Fowler may have seen his rendering of Il Principe as a way of gaining King James’s favor at a time when Fowler had become a peripheral member at the sovereign’s court. Consequently, the translator’s hybrid deployment of three different sources, together with his own additions and suppressions, were aimed to conform to James VI’s political and cultural project. The ideological convergences between the king’s political thought and Fowler’s manipulated Prince supported and legitimized the existing power structures of the target culture. The unfinished/unedited state of the manuscript may suggest that a total reconciliation between James’s markedly idealized vision of kingship and government and Machiavelli’s treatise was impossible despite the translator’s intercultural and ethnocentric appropriation of the source text.
Geospatial Narratives and Their Spatio-Temporal Dynamics: Commonsense Reasoning for High-Level Analyses in Geographic Information Systems
Authors: Bhatt Mehul , Wallgrün Jan
Published: February 2014

The modeling, analysis and visualization of dynamic geospatial phenomenahas been identified as a key developmental challenge for next-generation GeographicInformation Systems (GIS). In this context, the envisaged paradigmatic extensions tocontemporary foundational GIS technology raises fundamental questions concerning theontological, formal representational and (analytical) computational methods that wouldunderlie their spatial information theoretic underpinnings. We present the conceptualoverview and architecture for the development of high-level semantic and qualitativeanalytical capabilities for dynamic geospatial domains. Building on formal methods in theareas of commonsense reasoning, qualitative reasoning, spatial and temporal representationand reasoning, reasoning about actions and change and computational models of narrative,we identify concrete theoretical and practical challenges that accrue in the context offormal reasoning about space, events, actions and change. With this as a basis and withinthe backdrop of an illustrated scenario involving the spatio-temporal dynamics of urbannarratives, we address specific problems and solution techniques chiefly involving qualitativeabstraction, data integration and spatial consistency and practical geospatial abduction.
Recent Advance of Biological Molecular Imaging Based on Lanthanide-Doped Upconversion-Luminescent Nanomaterials
Authors: Min Yuanzeng , Li Jinming , Liu Fang , Padmanabhan Parasuraman , Yeow Edwin , Xing Bengang
Published: February 2014

Lanthanide-doped upconversion-luminescent nanoparticles (UCNPs), which can be excited by near-infrared (NIR) laser irradiation to emit multiplex light, have been proven to be very useful for in vitro and in vivo molecular imaging studies. In comparison with the conventionally used down-conversion fluorescence imaging strategies, the NIR light excited luminescence of UCNPs displays high photostability, low cytotoxicity, little background auto-fluorescence, which allows for deep tissue penetration, making them attractive as contrast agents for biomedical imaging applications. In this review, we will mainly focus on the latest development of a new type of lanthanide-doped UCNP material and its main applications for in vitro and in vivo molecular imaging and we will also discuss the challenges and future perspectives.
Clinical Manifestations and Outcomes of West Nile Virus Infection
Authors: Sejvar James
Published: February 2014

Since the emergence of West Nile virus (WNV) in North America in 1999, understanding of the clinical features, spectrum of illness and eventual functional outcomes of human illness has increased tremendously. Most human infections with WNV remain clinically silent. Among those persons developing symptomatic illness, most develop a self-limited febrile illness. More severe illness with WNV (West Nile neuroinvasive disease, WNND) is manifested as meningitis, encephalitis or an acute anterior (polio) myelitis. These manifestations are generally more prevalent in older persons or those with immunosuppression. In the future, a more thorough understanding of the long-term physical, cognitive and functional outcomes of persons recovering from WNV illness will be important in understanding the overall illness burden.

En s’appuyant sur des méthodes de collecte et d’analyse informationnelle, on peut élaborer des «  futurs probables  », anticiper les mutations et prévoir leurs effets. C’est là que réside la différence entre la prospective et la futurologie, ou encore la science-fiction. La prospective, comme l’intelligence économique, met la connaissance au service de l’action stratégique et de la décision. Nous voudrions ainsi, dans le cadre de ce dossier, réconcilier prospective et futurologie, «  ces deux sœurs ennemies affairées à sonder l’avenir  » 1 , afin d’imaginer des scénarios pour l’évolution du paysage informationnel et des métiers qui y sont liés.
La postmodernité de Xibaipo et l'aube de l'histoire universelle
Authors: Cui Zhiyuan , Wang Shuliu , Le Gall Pierre-Yves
Published: February 2014

D’après Toynbee, la postmodernité se caractérise par la montée de la classe ouvrière sur la scène politique et l’adoption de la modernité occidentale par les intellectuels non occidentaux. Mais pour le poète Olson, la postmodernité est post-occidentale. Deux Chinois assistaient à la rédaction de la Déclaration universelle des droits de l’homme, et ont influé sur sa rédaction. L’histoire universelle a besoin de la diversité.
Quel nom : nouveau travailleur, travailleur rural ou classe ouvrière ?

Published: February 2014

Les travailleurs qu’on rencontrait dans les villes chinoises, assignés juridiquement à résider dans les campagnes, pouvaient être dits ruraux. Aujourd’hui, on rencontre plutôt des travailleurs qui se disent citadins, mais qui ne sont pas pour autant ouvriers d’un point de vue culturel et politique. Leurs actions de résistance contre l’exploitation dans le travail sont réelles mais sporadiques. Ils ne sont pas capables d’utiliser les médias comme les nouveaux pauvres des pays occidentaux. Ils ne bénéficient pas des avantages matériels de la vieille classe ouvrière chinoise. Leur présence témoigne du fait que la production économique n’est plus aussi dépendante de l’État.
Pourquoi la Chine a-t-elle pu éviter de tomber dans les « pièges du développement » ?
Authors: Wen Tiejun , Cui Xue , Wang Shuliu , Le Gall Pierre-Yves
Published: February 2014

L’énigme chinoise, c’est qu’à partir de 1950, la Chine a pu rembourser ses dettes et consacrer ses moyens à sa propre croissance. C’est le monde rural qui a absorbé les crises cycliques liées à la présence du pays sur le marché mondial. D’où le renouveau d’intérêt du gouvernement pour les zones rurales dans le contexte de crise mondiale et l’investissement dans le bien-être de la population dans son ensemble.
Entretien avec François Godement (Asia Centre)

Published: February 2014

Les questions ouvertes par vos correspondants ont été refermées depuis la fin de 2012. Le Parti et l’État sont parvenus à mettre la conjoncture économique sous contrôle au prix d’un renforcement de la censure, d’un étouffement des mouvements sociaux et d’un semblant de redistribution. Mais pour la Chine, l’essentiel, ce sont les marchés extérieurs. Une économie dans laquelle les ménages épargnent la moitié de leurs gains n’est pas fondée sur la consommation de masse. C’est l’État qui a su gérer la formidable augmentation des investissements dans les infrastructures et le bâtiment, dont profite surtout l’élite. La question de l’environnement est nouvelle et fait peur ; elle est traitée en termes de responsabilité individuelle.

Les auteurs insistent sur la diversité des points de vue des auteurs chinois du numéro et sur le caractère central de la construction de l’État providence, ce qui différencie la Chine du Brésil par exemple. Ils croient, à la différence de François Godement, à des contradictions majeures qu’on verra émerger tôt ou tard, liées à des problèmes démographiques comme le vieillissement de la population, ou sociaux comme le rôle des femmes ou les conflits ethniques, ou à l’usage croissant des nouvelles technologies de communication. Les modèles culturels globalisés véhiculés par les réseaux sociaux, s’ils sont encore marginaux, ont une certaine emprise, comme le montre le développement des ONG.
Les mutuelles de sans-tickets

Published: February 2014

Cet article étudie les diverses façons dont des usagers des transports en communs s’organisent en collectifs pour inventer des moyens de se soustraire à une obligation de paiement qu’ils jugent inique. En formant des collectifs qui partagent les informations sur les contrôles de ticket, qui mutualisent le paiement des amendes et qui élaborent collectivement des dénonciations publiques de la politique des transports en communs, ils se situent à la limite entre l’action politique traditionnelle et un mode de résistance et d’esquive que l’auteure propose de qualifier d’ infrapolitique . Cette catégorie est esquissée ici à partir d’une relecture quelque peu décalée de la définition qu’en donne James C. Scott.

Capitalisme mental

Published: February 2014

La publicité constitue une forme d’occupation et d’exploitation de notre ressource la plus précieuse, notre attention, laquelle est en passe de devenir une forme de capital tout aussi déterminante dans nos logiques socio-économiques que la forme argent. Les technologies de l’attraction développées à une échelle industrielle par les mass-medias (d’abord analogiques, puis désormais numériques) entraînent la mise en place d’un nouveau type de « capitalisme mental ». Dans cet article qui résume l’ouvrage qu’il lui a consacré, Georg Franck propose toute une batterie de concepts et de principes, à la fois puissants et fins, pour analyser les nouveaux modes d’exploitation et les nouvelles sources de conflits sociaux qui se mettent en place à cette occasion.
Y a-t-il une araignée sur la toile ?
Authors: Moulier-Boutang Yann
Published: February 2014

Les discours dénonçant actuellement un retour de manivelle des mécanismes d’exploitation et des luttes de classes sur un Internet qu’on aurait assimilé trop rapidement à un vaste espace de liberté relèvent d’une mélancolie qui passe à côté des véritables nouveautés du capitalisme cognitif. Ils confondent exploitation et domination, et occultent la régression de la domination en soulignant la résurgence de nouvelles exploitations. Ils ratent également la spécificité d’une forme d’exploitation qui porte sur des intangibles et sur une puissance d’invention vouée à échapper à ce qui l’emprisonne.
Des placeurs sachant se placer ?
Authors: Bense Ferreira Alves Celia
Published: February 2014

À partir de l’analyse des rétributions du placement dans un théâtre parisien de grande renommée, cet article interroge le rapport des ouvreurs à leur implication organisationnelle et étudie les conditions de passage d’un « petit boulot » à un métier. Attirés par les rétributions directes de ce emploi de bas statut, les placeurs maintiennent leur participation sur la durée, car ils prennent un pari annexe externe  : être embauchés dans un métier du secteur culturel de meilleur statut. Pour ceux qui souhaitent devenir comédiens ou metteurs en scène, le placement offre de nombreuses rétributions indirectes en lien avec ces métiers ce qui les amène à redéfinir leur pari et miser sur une embauche au sein de l’organisation, à savoir prendre un pari annexe interne . Ceci conforte ainsi la cohérence des lignes d’activité et donc leur implication dans l’organisation mais peut les éloigner de la réalisation de la carrière professionnelle visée.
« Ça n'a pas de prix »
Authors: Bajard Flora , Perrenoud Marc
Published: February 2014

Cet article expose les formes de rétributions non monétaires observées chez des céramistes et autres artisans d’art, dans des espaces du travail indépendant, en marge des mondes de l’art les plus légitimes. La relative précarité économique de ces professionnels s’accompagne d’une quête de bonheur dans le travail qui semble évacuer, du moins en partie, la question du profit marchand. Réduire cette situation à une dénégation de l’économie et à une forme d ’illusio vocationnelle paraît impropre à restituer la « double vérité », objective et subjective, du rapport au travail de ces indépendants. En prenant au sérieux le sens que ces enquêtés donnent à leur activité, on montre qu’ils pensent les rétributions du travail dans toute la diversité de leurs formes. Cet article expose ainsi à quelles conditions le revenu pécuniaire s’articule alors avec d’autres types de bénéfices, qu’il s’agisse de la valeur axiologique du travail (travail de belle facture, artifié) ou d’une « qualité de vie » liée aux espaces et aux temps du travail.

A passive-walking of a double-legs planar Robot is considered. The dynamic equation of the system walking down a shallow slope, powered only by gravity is established according to Lagrange method. After the equation was transferred to a dimensionless one, it shows the motion is depended not only on the free parameter, the ramp slope γ, but also on the ratio of m/M, m is mass of the foot of the model and M is the mass of the hip as well; The analytic calculations show that at the identical ramp slope γ, the whole moving has different phases: stable period walking and chaos with the increasing of m/M. Its phase portraits and graph of step time interval show the influence to the motion because of the ratio of m/M.

Published: February 2014

Oxygen content controller in the closed environment contains two parts, master machine and slave machine, of which the master one in the control room can monitor and control the slave ones hanged on it. The master one can not only read the current value of the salve but also control the parameter values and set the upper and lower limits, and the slave one can set its own limits meanwhile. The slave machines monitor the current oxygen content by 4OX2 oxygen sensor, and convert the content signal into digital signal which is conventional to process by the microcontroller.And then the digital signal will be compared with the limit, if less than the lower limit, the relay will open the valve to release oxygen into the air. On the contrary, if more than the upper threshold, the valve will be closed. In addition, the slave machine also has the calibration function and set its own communication address using DIPswitches. The communication between the master and slave is accomplished by the full duplex RS485 through max489 chip.

Ride height adjustment of air suspension can be achieved by pumping air into or releasing air out of the air spring. However, energy loss would inevitably occur during the two processes,and test system of closed loop air suspension was established.Working process of the system was divided into three procedures as charging, discharging and boosting. Energy loss calculation method-compressed gas available energy was put forward, quantitative analysis of energy consumption during charging and discharging was carried out. Experiment results showed that energy consumption during charging process rises as initial air pressure of high pressure chamber increases, and during discharging and boosting processes, energy consumption decreases when initial air pressure of low pressure chamber increases. Under the same conditions, compared with open-loop air suspension, closed loop air suspension system with high & low pressure chambers can save plenty of energy.
