Les années 1990-2000 ont été marquées, en France, par l'émergence d'un courant de pensée et d'une nébuleuse d'acteurs intellectuels communément rassemblés sous l'étiquette des « Nouveaux Réactionnaires » (tels que Pascal Bruckner, Alain Finkielkraut, Alexandre Adler, Philippe Muray, Jean Clair, Éric Zemmour, Michel Houellebecq, etc.). Journalistes, romanciers, essayistes, chroniqueurs, philosophes, affichant une posture de refus à l'égard du politiquement correct, de la gauche morale et de la pensée unique, ils forment une sorte de personnage générique, composé de singularités en rupture avec toute assignation sociologique. Le projet de recherche entend dresser le tableau raisonné de ce collectif dispersé, sous les deux rapports d'une sociographie de groupe et d'une analyse rhétorique de leur discours ; il entend aussi mettre à l'épreuve différentes hypothèses explicatives sur l'émergence historique et politique du phénomène.

Pre-stress may have a consderable effect on the behaviour of thin walled structures. The general case is non linear. However, there is a class of situations where the study remains linear, as for example, a plate with a membranar pre-stress. The present paper focuses on the basic hypotheses of such a linearized analysis an on its exact formulation. [less ▲]

The matrix Lie group approach allows to formulate and solve the equations of motion of a multibody system in a parametrization-free framework. The kinematic joints and the rigidity constraints should also be formulated as constraint equations on the Lie group. Working on the Special Euclidean group SE(3), we introduce a method to obtain appropriate vectorial constraint equations in terms of mixed coordinates. Moreover, we present an absolute coordinates formulation, based on an relative coordinates elimination method, so that the minimum number of constraint equations necessary to describe the joints is used.

Purpose: Print 3G is a peptidic antagonist of oncoprotein involved in breast cancer, containing 25 amino acids. The purpose of this work is to study the peptide encapsulation into PEGylated liposomes composed of SPC:CHOL:mPEG-2000-DSPE (47:47:6). Methods: Loaded unilamellar vesicles were prepared by hydration of lipid film method. Unfortunately, a loss of Print 3G was observed during the different steps of this manufacturing technique giving rise to encapsulation efficiencies (EE) close to 0 %. Thus, the freeze-thawing method was used to enhance the amount of Print 3G encapsulated into blank liposomes prepared using the above procedure. Because many factors may influence the peptide entrapment into the vesicles (number of freeze-thawing cycles (NC), lipid concentration (LC), peptide concentration (PC) and mixing time (MT)), a design of experiment (DOE) was performed (for the screening, a Plackett and Burman plan; for the optimization, a central composite design). EE were calculated in terms of quantity of peptide loaded in liposomes as a function of quantity operated (EEp) or quantity of lipids (EEl). Results: The EE obtained by the freeze-thawing method in standard conditions (Katanasaka, Ida et al., 2008; Maeda, Bharate et al., 2008), amounted to 26.20 ± 7.98 %, n=3 (EEp) and to 0.26 ± 0.074 % (EEl). Among the different considered parameters, the screening permitted to identify two factors having a positive and significant influence on the EE: NC and LC. Concerning the PC and MT, no influence was revealed. For the second part of the DOE, the positive factors were optimized and obtained results revealed a theoretical optimum at 64.75 ± 3.55 % when 11 freeze-thawing cycles were applied (NC) and for the following LC: 36.1 mM SPC, 36.1 mM CHOL and 4mM mPEG-2000-DSPE. The experimental results showed an encapsulation efficiency of 62.68 ± 2.93 %. Photon correlation spectroscopy and freeze-fracture electron microscopy were also realized to examine the liposome integrity, before and after the freeze-thawing cycles. Conclusion: Changing the manufacturing technique permitted a significant encapsulation of Print 3G into liposomes. The DOE led to a significant improvement of encapsulation efficiencies.
