Amphiphilc molecules are one of the most important compounds in our planet owing to their fundamental role as catalysts of interfacial free energy in nature, biological systems, and manufacturated products [1]. Their chemical structure and configuration, which governs their properties and activities, may be classified in small, intermediate, and large sizes. To better understand the effect of such a parameter, the behaviors of various carbohydrate-based surfactants, from small to polymeric molecular structures at the air-water interface, and in bulk liquid for their ability to form and stabilize related colloidal systems like micelles and foams have been investigated. In particular, rheological properties including elasticity and viscosity components at the air-water interface have been determined by oscillatiory mode under different oscillation frequency and surfactant concentration conditions using a pending drop tensiometer system. Their micellar and foaming properties have been characterized and evaluated in terms of CMC-micelle size and formation-stability, respectively.

Le cinématographe – c’est une évidence – n’est pas né avec la notion d’acteur. L’acteur de cinéma est une instance qui s’est inventée progressivement, au registre de l’Histoire. Dans le cadre de cette communication, j'examine quelques-unes des modalités d’émergence de cette figure singulière. Dans le premier cinéma de fiction, tel qu’il s’impose au cours des années 1900, l’acteur de cinéma, comme corps en jeu, entre virtuellement en concurrence, tout particulièrement en cas de tournage en plein air, avec celui qui fut l’homme ordinaire du cinéma des tout premiers temps, à savoir le badaud, qu’il finira évidemment par supplanter. Encore cette substitution ne s’est-elle pas opérée instantanément : elle présente, elle aussi, une dimension forcément historique. Partant de là, il s’agit d’examiner une forme de régime transitoire dans les relations mettant aux prises ces deux corps de cinéma que sont le badaud et l’acteur. Pour ce faire, l’accent est placé moins sur des films que sur des moments d’images (plans ou fragments de plan) puisés dans quelques films des années 1900, dont "Daring Daylight Burglary" (F. Mottershaw, Sheffield Photographic Company, 1903), "The Ex-Convict" (E. S. Porter, Edison, 1904) et "Mésaventures d’un cycliste myope" (Éclipse, 1907). Dans ces quelques moments d’images, la coprésence du badaud et de l’acteur témoigne d’un état hybride ou clivé de la scène de cinéma : un état dans lequel l’acteur, institué en foyer d’attention, n’est pourtant pas encore mis en situation de monopoliser l’espace de la représentation ; un état dans lequel il doit composer avec la présence incidente du badaud, lequel incarne exemplairement la part d’hétérogène qu’enferme, à ses origines, la scène de cinéma.

The sexual addiction is an abnormal sexual practice. It becomes the center of the subject’s existence, by depriving him from other investments and without bringing him real satisfaction. This research project intends to explore the field of sexual addiction and a possible treatment for it. Several studies on sexual dysfunction treated with psychotherapy and virtual reality have shown that we obtain better results than if we use just the psychotherapy. [less ▲]

We survey here state of the art mass spectrometry methodologies for investigating G-quadruplexes, and will illustrate them with a new study on a simple model system: the dimeric G-quadruplex of the 12-mer telomeric DNA sequence d(TAGGGTTAGGGT), which can adopt either a parallel or an antiparallel structure. We will discuss the solution conditions compatible with electrospray ionisation, the quantification of complexes using ESI-MS, the interpretation of ammonium ion preservation in the complexes in the gas phase, and the use of ion mobility spectrometry to resolve ambiguities regarding the strand stoichiometry, or separate and characterise different structural isomers. We also describe that adding electrospray-compatible organic co-solvents (methanol, ethanol, isopropanol or acetonitrile) to aqueous ammonium acetate increases the stability and rate of formation of dimeric G-quadruplexes, and causes structural transitions to parallel structures. Structural changes were probed by circular dichroism and ion mobility spectrometry, and the excellent correlation between the two techniques validates the use of ion mobility to investigate G-quadruplex folding. We also demonstrate that parallel G-quadruplex structures are easier to preserve in the gas phase than antiparallel structures. [less ▲]

The results of this study reveal that the marketing of the main food products of Bas-Congo (cassava, plantain, maize, bean and groundnut) faces many constraints. Indeed, the food markets of Bas-Congo are characterized by inadequate infrastructures (transport, storage and processing), no-standard sale units, problems of information on the market, an informal operation, a large number of intermediaries and harassment on the roads and the markets. In the countryside, the peasants walk an average of 8 km to sell their small crop surplus in the rural markets. Financial constraints often force the wholesalers to turn to certain actors of the sector to finance the payment of marketing costs by giving up to them, in return, the exclusive right to sell their food products. These constraints have as consequences particularly high costs of transaction at the level of wholesalers of which the most important is the transportation which represents 46 to 61% of the total of these costs, significant margins on wholesale (45 to 68% of the wholesale price), etc. The study shows also a lack of spatial integration between Kimpese (Bas-Congo) and Kinshasa markets. Food markets actors adapt themselves by developing strategies in order to mitigate the impacts of these constraints and to maintain both production and marketing activities. [less ▲]
