Posthumanité et subjectivité transcendante dans l’œuvre de Philip K. Dick

La problématique à l’étude dans ce mémoire est la représentation et conceptualisation de la notion de posthumanité dans trois romans de Philip K.Dick : The Three Stigmata Of Palmer Eldritch, Do Androids Dream Of Electric Sheep? et Ubik. L’analyse de ces romans nous permettra de montrer que l’auteur américain focalise sa réflexion sur le posthumain sur la subjectivité transcendante de personnages qui absorbent, et se substituent à la réalité d’autres personnages dans leur environnement. Nous montrerons également que l’écriture de Dick a évolué vers une vision plus spirituelle ou mystique en se détachant graduellement du récit de science-fiction traditionnel. Ce développement aura des répercussions significatives sur sa postérité cyberpunk.

Studies on the Effect of High Energy Ball Milling On the Structural, Electrical and Magnetic Properties of Some Normal Spinets in the Ultrafine Regime

The present work is an attempt to understand the characteristics of high energy ball milling on the structural, electrical and magnetic properties of some normal spinets in the ultra fine regime, Magnetism and magnetic materials have been a fascinating subject for the mankind ever since the discovery of lodestone. Since then, man has been applying this principle of magnetism to build devices for various applications. Magnetism can be classified broadly into five categories. They are diamagnetic, paramagnetic, ferromagnetic antiferromagnetic and ferrimagnetic. Of these, ferro and ferri magnetic materials assume great commercial importance due to their unique properties like appropriate magnetic characteristics, high resistivity and low eddy current losses. The emergence of nanoscience and nanotechnology during the last decade had its impact in the field of magnetism and magnetic materials too. Now, it is common knowledge that materials synthesized in the nanoregime exhibit novel and superlative properties with respect to their coarser sized counterparts in the micron regime. These studies reveal that dielectric properties can be varied appreciably by high-energy ball milling in nanosized zinc ferrites produced by coprecipitation method. A semi conducting behaviour was observed in these materials with the Oxygen vacancies acting as the main charge carrier for conduction, which was produced at the time of coprecipitation and milling. Thus through this study, it was possible to successfully investigate the finite size effects on the structural, electrical and magnetic properties of normal spinels in the ultra fine regime

Enhanced shape anisotropy and magneto-optical birefringence by high energy ball milling in NixFe1−xFe2O4 ferrofluids

Ferrofluids belonging to the series NixFe1 xFe2O4 were synthesised by two different procedures—one by standard co-precipitation techniques, the other by co-precipitation for synthesis of particles and dispersion aided by high-energy ball milling with a view to understand the effect of strain and size anisotropy on the magneto-optical properties of ferrofluids. The birefringence measurements were carried out using a standard ellipsometer. The birefringence signal obtained for chemically synthesised samples was satisfactorily fitted to the standard second Langevin function. The ball-milled ferrofluids showed a deviation and their birefringence was enhanced by an order. This large enhancement in the birefringence value cannot be attributed to the increase in grain size of the samples, considering that the grain sizes of sample synthesised by both modes are comparable; instead, it can be attributed to the lattice strain-induced shape anisotropy(oblation) arising from the high-energy ball-milling process. Thus magnetic-optical (MO) signals can be tuned by ball-milling process, which can find potential applications.

Philip's history atlas : 2000 years of world and british history.

Veinte siglos de historia del mundo y de historia británica organizados cronológica y temáticamente en este Atlas de Historia. Contiene temas claves para estudiantes de secundaria desde el Imperio Romano y China Antigua hasta los conflictos del mundo y las operaciones pacificadoras en 1990.

The swing ball.

La etapa uno se centra en las habilidades de lenguaje oral y prelectura que los niños necesitan para ser lectores competentes. Esta etapa es esencial para:la introducción de los personajes principales. Alentar a los niños a conversar acerca de ellos mismos y sus experiencias en relación con las historias. El desarrollo de destrezas de escuchar. Se presentan las primeras palabras clave. El desarrollo de una actitud positiva hacia la lectura. La enseñanza de habilidades de manipulación del libro. Estas historias de Bif, Chip y Kipper sirven de base para hablar de temas como las relaciones entre hermanos, apodos, cumpleaños, la hora del baño, aprender algo nuevo, y así sucesivamente. Al hablar de sus propias experiencias, los niños sienten una participación personal en los acontecimientos de las historias. A Biff y a Chip les gusta jugar a la pelota. Jugar a la pelota en un pequeño jardín a veces puede dar lugar a problemas. Biff y Chip tienen todo tipo de dificultades cuando juegan en su jardín, hasta que papá tiene una idea muy buena.

L'Avancement du temps didactique lors des "moments à dominance verbale" en séance de basket-ball. Etude comparative chez un enseignant généraliste et un enseignant spécialiste

L’éducation physique (EP) est considérée comme une discipline fortement caractérisée par le «faire». Ce sont des mouvements, des gestes, des techniques ou des tactiques en situation et leurs résultats qui sont évalués. C’est aussi à travers le «faire moteur» que majoritairement est pensé le processus d’apprentissage des élèves. Toutefois, si les actions motrices se trouvent au centre des préoccupations disciplinaires, les leçons d’éducation physique comportent toujours une part, parfois assez importante, des «moments à dominance verbale» (MàDV). Ces derniers renvoient aux phases de la séance durant lesquelles l’enseignant et/ou les élèves communiquent verbalement (des gestes ou des démonstrations peuvent accompagner la parole). Le temps dédié aux consignes initiales, le temps des régulations après une situation de jeu ou le temps des feed-back sont des exemples typiques
