We propose a lattice model for studying the Brazil Nut Effect (BNE), i.e. the phase segregation occuring when a granular material is vertically shaked. The model considers the tap intensity and the mobility mu of the grains as the main physical parameters. Different mobilities for different grain species lead to segregation (BNE) patterns, reverse segregation (RBNE) patterns, "sandwhich" layered structures or vertical domains. A phase diagram (decompaction chi, mobility difference between both species Delta mu) is obtained in which the different phases are emphasized. In a narrow region of the diagram, different phases coexist. It is shown that the BNE segregation could be reversed by increasing the tap intensity or the characteristics of the grains. Numerical results are compared with earlier experimental works. [less ▲]

For generations, nomad herders have been learning to manage herd health, particularly in dromedary because of its high value. They have thus acquired a very comprehensive knowledge of camel's illness signs and have developed their own nomenclature. The present study aims at the description, scientific identification and recognition of this ethnoveterinary knowledge by means of an investigation carried out in Tuareg populations living in the neighbourhoods of Agadez (Niger). The dominant pathologies cited by herders for being the most alarming are gastro-intestinal helminthiasis (izni), camel calf diarrhoea (efay), tick infestations of camel calves (igardan), camel pox (erk eshik), sarcoptic mange (ajud) and bronchopneumonia (toza). Poorly identified nosologic entities are also reported. [less ▲]

Background: This series aims to prove the positive impact of laparoscopic approach in aortofemoral bypass grafting. Methods : It concerns a retrospective non randomized study comparing 58 consecutive patients treated with laparoscopic procedure (n = 30) and with a standard open procedure (n = 28) in a single center. The different operating times, the complications and the follow-up of these two groups are compared Results : The demographics and angiographic data of the two groups were comparable. Operating time was longer in the laparoscopic group. However, we noticed a significant shorter hospitalisation stay (p < 0.0001) after the laparoscopic procedure with a mean 5.1 days. There was no significant difference of morbidity. Conclusion : We suggest that the trans-peritoneal approach is the best way in laparoscopic procedure in term of exposure and ergonomics. Laparoscopic aortofemoral bypass grafting is feasible, safe and effective. Shortening of operating time is observed as surgeon's experience grows. [less ▲]

Metal profiles in lake sediments could provide historical environmental information on impacts caused by human activities and natural events, with view to the formulation of effective environmental policies. This paper presents data on sedimentary element profiles in Laguna Chica de San Pedro (LCSP) lake, located in the Bio Bio Region in Southern Chile, where important industrial activities are concentrated. Sediment properties (organic and inorganic matter, grain size, particle distribution, biogenic silica, Mn/ Fe ratio), major (Al, Ca, K, Mg, Ti, Na), trace (V, As, Co, Cu, Zn, Ni, Cr, Pb, Sr), and mobile (Fe, Mn, P, S) elements, as well as mineral profiles (plagioclase, quartz, clays, amorphous material) are presented, up to 65 cm depth. In general, relatively constant concentration profiles are observed in the sedimentary core middle section, for most elements. Most changes in composition are seen at the top (recent industrial period) and bottom (before human intervention) sections. Variable redox conditions, generated by biological activity at the sediment-water interface are likely to account for composition profiles at the sediment-water interface. On the other hand, physical processes seem to be mostly responsible for concentration changes in Pre-industrial sediments. Mineral content profiles, such as plagioclase, clay and quartz, as well as total clay content remain fairly constant in most of the core, showing significant changes at its bottom part. High excess V, As, and S values, especially at the upper sediment, arise as a consequence of redox conditions in the lake. Certainly, such metal enrichment is mainly associated with natural sedimentary matter supply from the watershed. [less ▲]

Experiment was carried out to investigate the effects of cottonseed meal (CSM) and Vitellaria paradoxa leaves in rainy season supplementation on milk yield, composition of the milk, live weight changes and their economical returns. To examine these effects, fifteen (15) Borgou cattle, in late lactation were offered three (3) dietary treatments: grazing natural pasture (control); the two other treatments received in addition cottonseed meal and Vitellaria paradoxa leaves supplements. The experiment lasted ten (10) weeks, including an adaptation period of two (2) weeks. Average daily milk yield was 946,58 g, 1690,07 g and 1176,89 g for the control, cottonseed meal and Vitellaria paradoxa leaves group respectively. Dietary treatments had a significant (p< 0,05) effect on milk yield during the trial. Only cows supplemented CSM produce significantly more milk than those unsupplemented (increasing of 78,54 %). But there is no differences among supplemented group. Cottonseed meal group produce more than 43,60 % milk yield compared to the second supplemented group. The treatments had a significant effect on total solid and milk ash. But no significant effect was observed on fat and protein content. The over all mean values were 15,12 %, 0,35 %, 5,92 % and 4,13 % respectively for total solid, ash, fat and protein content. There were no significant differences (p<0,05) in live weight changes of supplemented group cows. Further more, calves live weight changes were significantly different. Supplemented groups calves live weight increase was significantly more than those unsupplemented from birth to the end of the trial (212,06 g/d and 219,10 g/d versus 161,1 g/d). From birth to the beginning of the trial, only Vitellaria paradoxa leaves group calves had a significant increase in live weight changes. Only CSM group calves had a significant increase in live weight changes (124,98 g/d versus 53,54 g/d for non supplemented group calves) during the trial. Calves live weight changes from birth to the beginning of the trial were highly significantly correlated with those from birth to the end of the trial for all the experimental herd and for CSM group (r = 0,96 and r = 0,99). In other hand, these two live weight changes were slightly correlated for the control (r = 0,96) and Vitellaria paradoxa group (r = 0,97). A net return analysis shows that cottonseed meal and Vitellaria paradoxa supplementation in rainy season was profitable even if Vitellaria paradoxa was more beneficial. [less ▲]

The ISO 14001 standard is currently the worldwide reference for Environmental Management System. For it has been produced at and for international level, how does it become embedded in local situations and action context. This article highlights the role of expertise in this embedding process in the framework of conceptual and methodological repertory of the sociology of translation. We firstly describe activities and actors that are involved in certification. Then our analyse is focused on triple role of environmental management expertise in embeddedness process of ISO 14001 standard: translation, netting and experience capitalization. [less ▲]

Consciousness has two main components: wakefulness and awareness. The vegetative state is characterized by wakefulness without awareness. Recent functional neuroimaging results have shown that some parts of the cortex are still functioning in 'vegetative' patients. External stimulation, such as a painful stimulus, still activates 'primary' sensory cortices in these patients but these areas are functionally disconnected from 'higher order' associative areas needed for awareness. Such studies are disentangling the neural correlates of the vegetative state from the minimally conscious state, and have major clinical consequences in addition to empirical importance for the understanding of consciousness.

Les auteurs montrent que dans le cadre de l'imporisition d'une "bonne gouvernance" en République du Bénin, les ONG locales jouent à présent un rôle central dans la constitution d'une société civile. L'espace social de la société civile implique aujourd'hui les leaders des nouvelles ONG très dépendantes des bailleurs occidentaux mais aussi les agents étatiques qui tentent de se positionner comme acteur au sein des nouveaux secteurs ONG tout en conservant leur fonction publique. Le processus d'émergence d'une société civile au Bénin ne peut se résumer ni à une privatisation de l'Etat ni à une étatisation de la société civile. [less ▲]
