In solar energy converting systems, a particular attention is paid to the orientation of solar collectors in order to optimize the overall system efficiency. In this context, the collectors can be fixed or oriented by a continuous solar tracking system. The proposed approach is based on METEOSAT images processing in order to detect the cloud coverage and its duration. These two parameters are treated by a fuzzy inference system deciding the optimal position of the solar panel. In fact, three weather cases can be considered: clear, partly covered or overcast sky. In the first case, the direct sunlight is more important than the diffuse radiation, thus the panel is always pointed towards the sun. In the overcast case, the solar beam is close to zero and the panel is placed horizontally to receive the diffuse radiation. Under partly covered conditions, the fuzzy inference system decides which of the previous positions is more efficient. The proposed approach is implemented using experimental prototype located in Perpignan (France). On a period of 17 months, the results are very satisfactory, with power gains of up to 23 % compared to the collectors oriented by a continuous solar tracking. © Published under licence by IOP Publishing Ltd.

Next to modern therapeutic, many plants resulting from the African traditional pharmacopeia are used by the traditional healers as anti-hemorrhoidal remedies. The aim of this study was to evaluate the anti-hemorrhoidal activity of leaves of Adenia lobata. This work has focused on the inflammatory aspect of the hemorrhoid. Induction of inflammation was made with kaolin mixed with arabic gum. Solutions of A. lobata leaves used with preventive measure delay the inflammatory process of hemorrhoidal disease and for curative cure hemorrhoidal inflammation. Also, the anti-inflammatory activity observed is due to flavonoids present in leaves of A. lobata. Preparation of solutions with cool water is more effective than that carried out with the hot water which denatures the active ingredients of the remedy. At the doses used, this remedy is deprived of acute toxicity and can be taken safety by patients. A six times higher solution concentration than that of the traditional healer gives a similar anti-inflammatory response to it. Thus, there is a minimum concentration of A. lobata leaves solutions from which the anti-inflammatory effect is maximal. The anti-hemorrhoidal action of leaves of A. lobata was established and tests on veinotonic aspect are in progress. © RJPT All right reserved.

During the African Monsoon Multidisciplinary Analysis (AMMA) field campaign, polarimetric weather radars, a rain-gauge network and disdrometers were available to analyse the convective systems and the rainfall in Benin. In this paper a three-year dataset of drop size distributions is used to compute theoretical relationships between X-band polarimetric variables and the rain rate, adjusted for the region of interest. The variability of these relationships from storm to storm and between rain types is studied. With an X-band polarimetric radar the rain rate can be retrieved from the differential specific phase shift K DP, the specific attenuation AH, the reflectivity Z or differential reflectivity ZDR corrected for attenuation, or a combination of these variables. The set of coefficients needed to run the rain retrieval or the attenuation correction schemes under the conditions found in Benin are computed. The rain retrieval schemes are compared on the basis of simulations. The retrievals based on one single propagative variable like K DP or A H perform well. Preliminary results from direct comparisons between X-band polarimetric radar estimates and rain-gauges are consistent with the disdrometer-based analysis. © 2010 Royal Meteorological Society.


The obturating prostheses of the jawbone and the prostheses of rebuilding of the mandible make it possible to restore the losses of substance of the jawbone and of the mandible and to cure the functional and Aesthetic disorders which result from these losses of substance. The success of these prosthetic restorations can be compromised by technical, economic and cultural factors. The principal factors are the importance of the losses of substance, the reduced number of teeth, the poverty of the technical plate, the persistence of certain traditional concepts. The fight against these factors requires the promotion of therapeutic associations in maxillo-facial cancerology, the sensitizing of the populations to the early hospital consultations, the improvement of the technical plate of the prosthesis of the jawbone and the face, the facilitation of the access of the most underprivileged groups to the prosthetic restorations, the promotion of multi-field collaboration, the whole co-operation of the patient throughout the treatment and the follow-up postprothetic.


Coronal-radicular restoration is the coronal reconstruction of an endodontically treated tooth, with a support on and in the root. The objective of this study is to assess the importance of the carried coronal-radicular restorations in the dental practice in Abidjan. It is about a prospective survey of 100 dental surgeons practicing in the city of Abidjan, pulled at random. The information was collected through a self-interview. As results, 79% of our population knows and performs coronal-radicular restorations especially in the absence of 3 dental walls but at a very low, less of 5/month for 90% of this population. The protocol of realization seems well known and followed for the majority of the pooled practitioners. However, we deplored often absence of radiography in the protocol and also the exclusive use of metal posts. In conclusion, the coronal-radicular restorations are much used in the daily practice in Côte d'Ivoire. The protocol for achieving this type of restoration seems well known and followed by the practitioners according to our study. However, as material all the dentists are still in the screw post (metal post). The adhesive technologies using fiber posts don't seem accessible to our people.
