Mon corps est-il un objet parmi d'autres dans l'espace ou bien crée-t-il l'étendue qu'il perçoit jusqu'à l'écho des étoiles? À quelle spatialité suis-je assujetti pour être relié de l'intérieur au monde et aux autres corps qui m'entourent? Les dimensions de l'espace sont-elles des coordonnées de la matière morte ou sont-elles des variations modales de mon esprit? C'est à la découverte de la spatialité du corps vivant que nous invite Guy-Félix Duportail dans son Analytique de la chair. il nous apprend, entre (...) autres, que la phénoménologie et la psychanalyse se rencontrent en ces lieux de la chair suivant des principes topologiques communs. Guy-Félix Duportail dessine le schéma intérieur de la subjectivité comme se donnant à l'extérieur, dans le monde. La subjectivité incarnée se retourne comme un gant et se retrouve ainsi exposée au-dehors, dans son sinthome, comme disait Lacan, dans son implexe, comme disait Merleau-Ponty. Dans tous les cas, elle se réalise dans une création réparatrice de son mal-être. L'immanence est donc dans la transcendance, et l'espace-temps se réfléchit dans la chair, dans les tourbillons de sa jouissance. La présente Analytique de la chair révèle qu'un corps sans organes (Deleuze et Guattari) est certes moins qu'un noeud, mais demeure plus qu'un emmêlement, et qu'une chair sublime mais sans corps (Levinas, Henry) ne fait du visage qu'un masque, et de la Vie glorieuse du Moi qu'un éloge de la pulsion de mort.

Nucleation and motion of kink pairs on partial dislocations are examined by elasticity theory for materials with a high Peierls stress. Two approaches are used: one considers the change in average stacking-fault energy due to alloying elements and the other considers the change in local SFE due to a nearby solute atom. Both approaches highlight the role of SFE on kink nucleation, propagation and annihilation and both furnish strain rate as a function of stress, temperature and SFE. Model predictions are (...) compared with yield stress data for two systems: firstly, an intermetallic, MoSi 2 , which softens for alloying elements that decrease the SFE and hardens for Re additions that increase the SFE; secondly, a ceramic oxide, MgO-Al 2 O 3 spinel, which softens with increasing addition of excess alumina and at the same time exhibits a decrease in SFE. The average SFE approach agrees qualitatively with the data while quantitative agreement is obtained with the local SFE approach. The possibility is considered that the model applies to other materials, such as TiAl, HfV 2 and Fe 3 Al, which show softening with certain alloying additions. One requirement is that the dislocations are dissociated more than a few atomic distances; otherwise kink nucleation occurs on the perfect dislocation . Hence the model does not apply to materials such as bcc metals which only have a core dissociation. Normal hardening effects of solutes from size and modulus misfits are additive with any softening effects from a decrease in SFE and so may mask the latter, as occurs for W additions to MoSi 2.

En sus Escolios, Nicolás Gómez Dávila hace manifiesta la relación existente entre las antiguas nociones gnósticas y las pretensiones ilustradas de la modernidad. Al determinar los fundamentos del gnosticismo en un conocimiento que se eleva sobre la fe, ubica rasgos análogos en el pensamiento moderno..

Ce dialogue à deux voix s'interroge sur le concept de réification, partant de la critique de la société bourgeoise et capitaliste proposée par le jeune Lukács dans son fameux essai La réification et la conscience de classe, pour se diriger par la suite vers une analyse minutieuse de la critique radicale de la réification et du fétichisme de la marchandise, articulée par Guy Debord dans La Société du Spectacle. Dans un troisième moment, la discussion théorique et philosophique s'intéresse à la (...) façon avec laquelle l'être social réifié et aliéné de la société capitaliste laisse ses traces dans la pensée philosophique moderne, à partir au moins du 18ème siècle. Autrement dit, on s'est donné comme tâche de mettre en lumière les antinomies de la pensée bourgeoise et ses rapports complexes aussi bien que profonds avec la société bourgeoise"--Page 4 of cover.

On the celebrations of the 50th anniversary of the opening of the Second Vatican Council and the 20th anniversary since the publication of The Catechism of the Catholic Church, Benedict XVI published a Letter entitled Porta Fidei, in which it was promulgated the Year of Faith. It began on November 11th 2012 and expired onl November 24th 2013. The year of 2012 was also when the XIII Ordinary General Assembly of the Synod of Bishops about The New Evangelization for the (...) Transmission of the Christian Faith took place. On the Apostolic Letter Porta Fidei, Benedict XVI remembered that in the current days faith cannot be assumed in society and also pointed out the importance of rediscovering it, to "show the joy of meeting Christ”, welcoming the grace and the teachings of the Second Vatican Council and the contribution of the Church's Catechism to The New Evangelization for the preaching of the Christian faith. We understand that pointing out the strength and beauty of faith means to present it in a new way to man, keeping its essential integrity. Such exercise isn’t just a challenge for the Church, but also an urgent task and an important contribution to the complete formation of the human being. To say the same thing in a new way we must always come from a source which is capable of preserving and renewing our faith. The primary source of faith is the Divine Revelation and therefore this is also the source of the proclamation of the Gospel. This idea, for us, is decisive for the matter of faith and its announcement, which is found in the Dogmatic Constitution Dei Verbum on Divine Revelation. Therefore our article will develop this idea based on Dei Verbum and it intends to be a contribution to catechesis, understood as a process of initiation into the Christian life or life in faith.

Estigmatizada por milhares de anos de perseguição, a fé judaica, tal como a conhecemos hoje, é marcada tanto pela figura de Abraão e pela lei de Moisés como pelas práticas de resistência e adaptação a contextos sociais adversos e de cariz inquisitorial. Fenómeno muito estudado à luz dos acontecimentos trágicos do século XX, as práticas persecutórias das comunidades hebraicas ao longo dos tempos conhecem no campo historiográfico um volumoso número de trabalhos. Contudo, a influência que este t...

Employing an aero-acoustic levitator, the Fe 2 O 3 -16.5 mol% La 2 O 3 eutectic alloy was levitated, melted, undercooled and then solidified under a containerless condition when a continuous laser beam heating system was incorporated. By revealing the surface and cross-sectional microstructures, copious nucleation is confirmed to take place in the undercooled melts solidified by either an external seeding or spontaneous crystallization. The nucleation behaviour of eutectic alloys is summarized, indicating that copious nucleation may be an intrinsic attribute (...) of a eutectic system with the exact eutectic composition in unconstrained solidification. Considering the complexity level of crystal structures of eutectic oxide phases in the Fe 2 O 3 -La 2 O 3 alloy, the linear kinetic constants are approximately estimated and the growth kinetics are discussed. The sluggish growth kinetics of the perovskite-type phase, that is LaFeO 3 with a higher complexity level in a unit cell leads to a decoupled growth within a single eutectic colony when the melt is undercooled to exceed the critical undercooling j T = 125 K. It is the decoupled growth that results in the formation of anomalous eutectics. The present concept based on the kinetic constant of different phases can also be applicable to account for the growth behaviour of other oxide eutectics when considering the stable and metastable eutectic reactions in different solidification conditions. The nucleation behaviour and growth modes in some oxide eutectic systems have been predicted in the free solidification from an undercooled state. (shrink)
