In 1994, during the International Conference on Population and Development convened by the United Nations in Cairo, a shocking video was shown, realized by an operator of CNN and depicting the circumcision of a ten-year-old child living in this very same city. Discourses around female circumcision were not new in Egypt and in the international community, but what was considered as a new episode of a recurrent scandal (not the last one indeed) led to enhance the "war against bad government"[1]. A war fought by means of ideological weapons produced by expert knowledges among which the medical and the feminist ones. The assignment of a value to the state of integrity of the female body and to the women freedom of choice, both designed according to Western canons, led to different actions to “save” Egyptian women. In this context, development agencies fosters a widespread representation of the victim, constituted by the woman mutilated body. Such representation is functional to put in place programs which do not guarantee a freedom of choice, but rather require adherence to another female model, one that defines the "modern" woman. My article, based on ethnographic experience, aims at highlighting the complexity of such dynamics and the role played by humanitarianism within them. Female body becomes the arena where local and international economic powers operate, disregarding a real understanding of the practice, its meanings and its eventual change. ________________________________________ [1] Foucault, Michel.

N-Heterocyclic carbenes are now commonly encountered in organometallic and inorganic coordination chemistry. The increasing attention they enjoy is due to their ability to act as ancillary ligands in a growing number of transition metal catalysts or even to play the role of nucleophilic reagents and catalysts in diverse organic transformations. As a fine addition to the NHC-Ru-alkylidenes, popular for their tremendous success in metathesis chemistry, an array of robust and stable Ru-NHCs has proven their utility in non-metathetical reactions. The present review surveys different classes of Ru-NHCs and their applications as efficient catalysts (or precatalysts) in several types of fundamental organic processes e.g. hydrogenation, hydrogen transfer, isomerization, cycloisomerization, cyclopropanation, hydrosilylation, allylation and deallylation, enol-ester synthesis, heterocycle synthesis, C-C alkyne coupling, Kharasch addition and ATRP. A special section is devoted to tandem processes some of which include concurrent or sequential metathesis steps. Relevant mechanistic and stereochemical aspects related to NHC-Ru catalysis will be highlighted. (c) 2006 Elsevier B.V. All rights reserved. [less ▲]

This poster summarize the firsts results of the PhD project started on October 2012 about the catalytic purification of biogas. The aim of this project consists in the development of Ni/Al2O3 catalyst in order to reform the tars present in the outlet gas of biomass gasifier. In order to obtain catalysts with high performance and lifetime, materials need to have optimized specific surface and metal particle dispersion. This poster investigate the effect of different surfactants (Pluronic P123; F127; stéarique acide, EDAS) on the materials properties. [less ▲]

The routine use of arterial grafts in coronary surgery is facilitated by peroperative adjunction of antispasmodic drug to reduce the event of spasm. Diltiazem has been favoured in most clinical studies devoted to the radial artery graft. The aim of this study was to assess the efficacy of a spasm preventing protocol associating hydrostatic dilation of the graft with a diluted solution of papaverine and nicardipine infusion, starting preoperatively and continued postoperatively in i.v. and per os forms. Between September 1996 and March 1997, a consecutive series of 50 patients underwent myocardial revascularization using the radial artery. The radial artery was prepared by hydrostatic dilation with papaverine (1%) and nicardipine was administrated at 0.25 microgram/kg/min and titrated according to the arterial systemic pressure. Operative mortality was 4% (sepsis). There was no evidence of perioperative MI nor hypoperfusion syndrome. Mean CKMB level at 18 hours was 36 micrograms/l. No ischaemic anomalies of the ECG were detected. Angiography performed in the last 20 patients showed a 98% (51/52) permeability rate for all graft; 19/20 radial grafts (95%) were patent. One radial graft presented a 50% stenosis at the proximal anastomosis, and another a moderate spasm (40%) in the middle part of the conduit. This study confirms that the radial artery conduit can be used with satisfactory results for routine coronary artery bypass. The use of nicardipine allows the control the vasoreactivity of the radial graft without totally obviating at least angiographic spasm. This drug is easy to titrate, and well tolerated in association to beta-blockers in the routine perioperative management of the coronary patients. [less ▲]

The main goals of our study is to verify the existence and extent of niche conservatism in three closely related species within the genus Lepilemur, and to draw conclusions on the applicability of conservation protocols to a broader array of Lepilemur species. The genus is an exemplary of the mammalian fauna of Madagascar which high biological diversity is under increasingly severe threat from anthropogenic degradation of its forest habitats. This study focuses particularly on three poorly-known Lepilemur taxa: L. sahamalazensis, L. dorsalis and L. mittermeieri, uplisted into one of the threatened categories of the IUCN Red List.The genus is particularly negatively affected by deforestation and habitat fragmentation and all have a small distribution range, fairly small total populations. Their pattern of distribution appears to have been established through vicariant speciation, probably driven by changes in the configuration of the hydrographic system. Such a pattern permits to expect a high level of niche conservatism. We present here our preliminary results of an exploratory mission on 1) evaluation of Lepilemur abundance in forest patches on the Ampasindava Peninsula, the Sahamalaza Peninsula and the Manongarivo Special Reserve 2) sleeping sites characteristics of the three studied species.

Termites represent one of the most abundant belowground animal taxa in tropical rainforests, where their species richness is much higher than in any other ecosystem. This high diversity in soil ecosystems is however difficult to explain by classical Hutchinsonian niche theory, as there is little evidence for spatial or temporal separation between species. Using δ13C and δ15N isotopic ratios, we tested if resource partitioning along the humification gradient occurs in neotropical soldierless termites of the Anoplotermes-group. Two distinct sites were investigated to check if interspecific differences are transposable between sites. Significant differences in δ15N were found between species of the Anoplotermes-group. Although some species displayed higher intersite δ15N variation than others, species-average δ15N values for both sites were highly correlated, showing that sympatric soldierless soil-feeding termites feed on distinct components of the soil. Our data also suggest that some species are more likely to shift along this gradient than others, in response to overall habitat conditions or to the presence of competitors. Feeding niche differentiation can therefore account for the high species richness and diversity of soldierless soil-feeding termites in neotropical rainforests. [less ▲]

In this study we investigated the climatic niche between and within closely related tropical tree species of the Erythrophleum genus (Fabaceae, Caesalpinioideae): E. ivorense, E. suaveolens and E. africanum. Two major hypotheses, the refuge theory and the ecological gradient hypothesis, have been developed to explain the current distribution of tree clades across tropical Africa. To identify the speciation mechanisms, we used a combination of geographic data and environmental factors to quantify the degree of niche conservatism (or divergence). We used two sets of distribution data for the purpose of this study. Species distribution data for the whole of tropical Africa was gathered from herbarium records. Distribution data of the two sister species E. ivorense and E. suaveolens assigned to genetic cluster were available for the lowland tropical forests of western and central Africa. Using a Species Distribution Model approach based on MaxEnt algorithm we tested for the environmental differences between species and genetic clusters within species. At species level, the climatic niche significantly differed and only slightly overlapped, suggesting a parapatric speciation along a climatic gradient. Within the two sister species, the niche of the parapatric central African genetic clusters suggests mostly a secondary contact following the recolonization from different forest refugia. [less ▲]
