Le 25 novembre dernier, notre Université recevait Sir John Houghton, professeur de physique atmosphérique à l'université d'Oxford, spécialiste des changements climatiques. Celui-ci se voyait attribuer le prix Albert Einstein décerné par le prestigieux Conseil culturel mondial. Avant la cérémonie officielle, John Houghton a tenu à faire un exposé "à destination des étudiants et des jeunes chercheurs" dans l'amphithéâtre principal de l'Institut de géographie, trop petit pour l'occasion. Une occasion extraordinaire de boire les paroles de cette brillante référence qui, pendant près de 15 ans, a coprésidé le Groupe d'experts intergouvernemental sur l'évolution du climat (Giec).

Summative writing assessment is an evaluative practice that aims, at least theoretically, to inform each student about his performance in that skill at a given time, and to help him to understand his errors so that he can make progress in his learning. In this article, we analyse summative writing assessment through various prisms. At the macro level, we discuss the reforms of the education system pertaining to assessment ; at the meso level, we target the assessment tools offered by the same education system, as well as the attention that may or may not be paid to remediation ; at the micro level, we deal with the issue of corrective feedback which students receive on their written production. By crossing these different sources (legal provisions, interviews, surveys, analysis of students’ annotated written production, etc.), we conclude that this practice may present major risks of inequality.

Il s’agit d’une analyse approfondie de la copie de la "Cène" de Léonard de Vinci qui est conservée depuis 1545 à l’abbaye prémontrée de Tongerlo. Dans cet article, nous retraçons l’histoire mouvementée de l’œuvre. Nous présentons également les résultats de la campagne d’examens scientifiques (réflectographies à l’infrarouge, photographies et mesures) qui a été réalisée sur cette peinture par le Centre européen d’Archéométrie (Université de Liège). Ces investigations ont permis de conclure à l’utilisation de poncifs, ce qui explique la fidélité de la copie par rapport à l’original tant du point de vue de l’iconographie que de celui des dimensions.

Cette étude participe à une réflexion sur la notion de faux et de contrefaçon à la Renaissance, quand la copie d'une image n'est pas considérée comme un faux et que sa pratique même intervient dans la formation artistique. A cet égard, le cas des "copies" de la "Cène" de Léonard de Vinci s'avère éclairant : aucune des nombreuses reproductions anciennes de la peinture murale n'est considérée comme autographe, aucune ne reproduit exactement l'ensemble de la composition, toutes sortes de variations étant apportées par les artistes. Aussi, peut-on s'interroger sur le statut de ces reproductions infidèles qui interprètent la "Cène" plus qu'elles ne la copient. [less ▲]

During the last decade, the Niger’s population has been affected by the food crisis (2001, 2004-2005, 2008, 2010-2011). Each year, she is subjected to many structural and temporary shocks. The structural shocks are caused by the chronicle difficulties (income) while the temporary shocks are tied at the "natural" disasters such as the hydrometeorological disasters, demographic crisis. The risk that the people fall in a state of food insecurity because of structural and temporary shocks is characterized by food vulnerability. The food vulnerability is defined as “the analysis of coping strategies and reactions faced with the structural or/and temporary shocks, if the coping strategies are not effectives, the people have in a temporary or structural food vulnerability” (Andres L. and Lebailly Ph., 2011). The target of this paper is to demonstrate the diversity of coping strategies in the different departments of Niger. The database is created as from an annual survey realized by the Early Alert System (EAS) and the Statistical National Institute of Niger (INS). This survey characterizes the state of food insecurity of households of Niger. The investigations of the household are based on stratified sampling. It exists two levels: region and enumeration areas. The investigations of the household are based from the database of the population census of 2001. This population census has determined the “enumeration areas”. These “enumeration areas” are defined as a “geographical area of 200 households on average” (INS, 2007). The sample of this investigation is established from a significant sample a point of view of the departments of Niger. The time period studied is spread the 2008 at 2011. The results have demonstrated that the departments of Tchintarabaden, Abalak, Tessaoua and Magaria have weakest number of collective meals, and the highest percentage of household practicing of selling the goods and land. Furthermore, the Niger’s population develops many strategies to struggle against the shocks. [less ▲]

A considerable fraction of life develops in the sea at temperatures lower than 15 degrees C. Little is known about the adaptive features selected under those conditions. We present the analysis of the genome Sequence of the fast growing Antarctica bacterium Pseudoalteromonas haloplanktis TAC125. We find that it copes with the increased Solubility of oxygen at low temperature by multiplying dioxygen scavenging while deleting whole pathways producing reactive oxygen species. Dioxygen-consuming lipid desaturases achieve both protection against oxygen and synthesis of lipids making the membrane fluid. A remarkable strategy for avoidance of reactive oxygen species generation is developed by A haloplanktis, with elimination of the ubiquitous molybdopterin-dependent metabolism. The A haloplanktis proteome reveals a concerted amino acid usage bias specific to psychrophiles, consistently appearing apt to accommodate asparagine, a residue prone to make proteins age. Adding to its originality, A haloplanktis further differs from its marine Counterparts with recruitment of a plasmid origin of replication for its second chromosome. [less ▲]

BACKGROUND: Acne is a multifactorial disease exhibiting distinct clinical presentations. Among them, the catamenial type is a matter of concern for young women. Some oral contraceptives may help without, however, clearing the skin condition. AIM: The present open study aimed at evaluating the effect of overnight applications of a paste made of petrolatum,15% zinc oxide and 0.25% miconazole nitrate. METHOD: The split-face trial was conducted in 35 women. A non-medicated cream was used as control. Clinical evaluations and biometrological assessments on cyanoacrylate follicular biopsies were performed monthly for 3 months. Comedometry and the density in autofluorescent follicular casts were used as analytical parameters. In addition, the five most severe cases at inclusion were tested at the completion of the study for follicular bacterial viability using dual flow cytometry. RESULTS: Compared with baseline and to the control hemi-face, the medicated paste brought significant improvement of acne. The number of papules and their redness were reduced beginning with the first treatment phase. A reduction in the follicular fluorescence was yielded beginning with the second treatment phase. The ratios between injured and dead bacteria, on the one hand, and live bacteria, on the other hand were significantly increased at completion of the study. CONCLUSION: A miconazole paste applied for 1 week at the end of the ovarian cycle has a beneficial effect on catamenial acne. [less ▲]

The cobalt-mediated radical polymerization of vinyl acetate was extended to copolymerization with I-alkenes (ethylene or 1-octene). In agreement with the low amount of I-alkene that could be incorporated into the copolymer, a gradient structure was predictable, but a. rather low polydispersity was observed. A poly(vinyl acetate)-b-poly(octene) copolymer was also successfully synthesized, leading to a poly (vinyl alcohol)-b-poly(octene) amphiphilic copolymer upon the methanolysis of the poly (vinyl acetate) block.

New copolymers of E-caprolactone (CL) and gamma-bromo-epsilon-caprolactone quaternized by pyridine (Py + CL) were investigated as non-viral vectors for gene delivery. Copolymers with two molar compositions (50 Py + CL/50 CL and 80 Py + CL/20 CL), each with a diblock or a random structure, were used to prepare nanoparticulate complexes with DNA. Average size and surface charge of the complexes and extent of the complexation were measured. The DNA condensation by the copolymers was analysed by a gel retardation assay. Cytotoxicity and transfection efficiency of the copolymers were also evaluated in HeLa cells and compared with polyethylenimme 50 kDa. The size of the polyplexes was approximately 200 nm. The zeta potential first increased with the copolymer/DNA charge ratio and became positive for charge ratios in the 2-4 range depending on the type of copolymer. DNA was completely condensed within the nanoparticles and the degree of interaction was very high. Cytotoxicity and transfection efficiency were found to be comparable to polyethylenimine 50 kDa. The experimental results suggest that the novel copolymers can be used as novel gene delivery vectors. [less ▲]
