The aim of this study was to evaluate the level of protection of employees who are exposed to radiation in a level III hospital establishment. It was a.d.scriptive cross-sectional survey of six months’ duration, involving eight level III Hospitals (Aristide Le dantec, Fann, Hoggy, Hear, Abass Ndao, Pikine, Touba, a.d.Thiès) in Senegal. Sixty-one of the one hundred questionnaires were recovered (overall response rate of 61%). The population of the study was mainly female (54.1%). The average age was 38.57 with extremes ranging from 23 to 65 years old. In the places where ionizing radiation sources are ha.d.ed, only at the Aristide Le dantec Hospital did we find a “competent person in radiation protection”. This explained the lack of a classification of employees a.d.work areas. Forty out of sixty-one (73.77%) had no knowledge of the basic principles of radiation protection (justification, optimisation, dose limitation) a.d.had not ever taken radiation holidays. For radiovigilance, exposure time limits to ionizing radiation concerned only 29/61 or 47.54% of the study population. The inverse square law of distance was known by only 40 workers, of whom 15 had no compliance. We found the presence of dosifilms in only 7/61 or 11.47% of the workers. On the other ha.d. the use of lead aprons was well established a.d.concerned 57/61 workers, i.e., 93.44%. In sum, ionizing radiation causes adverse health effects. The absence of a good radiation protection culture in Senegal requires the presence of at least 4 to 5 competent persons in radiation protection for quality training of workers in radiobiology, radiopathology a.d.radiation protection.

The aim of this study was to examine whether the offering of traditional treatments can constitute a positive contribution to integrate in an oral public health care settings. Method: This was a cross-sectional study involving 300 people living in the area of Ferlo in East Central Senegal. Selected individuals must be residents of the area over the age of 15 years. Cluster sampling was used as a recruitment method. data collected concerned the type of oral health care used whether modern or traditional, the periodontal condition (plaque, gingival a.d.bleeding index, attachment loss, pocket depth a.d.CPITN). dental status was evaluated by dMFT. The data were analyzed with R software a.d.the Student’s t test was used to compare the averages of indices in both groups at the threshold of 5%. A co-variance analysis was allowed in order to determine associations between some indices a.d.therapy type in multivariate approach. Results: Averages of dental a.d.periodontal indices were globally higher in people using modern therapies. dMFT, CPITN a.d.gingival index increased significantly when the type of therapy was modern after adjustment on the plaque index a.d.age. Conclusion: The traditional dentistry could constitute a positive contribution to a public health care, especially in a context of developing country. However, this practice should be guided a.d.validated by a research-based evidence to allow better use of the therapeutic processes, a.d.promote the health of populations.

We present three 3d numerical models of deep subduction where buoyant material from an oceanic plateau a.d.a plume interact with the overriding plate to assess the influence on subduction dynamics, trench geometry, a.d.mechanisms for plateau accretion a.d.continental growth. Transient instabilities of the convergent margin are produced, resulting in： contorted trench geometry; trench migration parallel with the plate margin; folding of the subducting slab a.d.orocline development at the convergent margin; a.d.transfer of the plateau to the overriding plate. The presence of plume material beneath the oceanic plateau causes fiat subduction above the plume, resulting in a ＂bowed＂ shaped subducting slab. In plateau-only models, plateau accretion at the edge of the overriding plate results in trench migration around the edge of the plateau before subduction is re-established directly behind the trailing edge of the plateau. The plateau shortens a.d.some plateau material subducts. The presence of buoyant plume material beneath the oceanic plateau has a profound influence on the behaviour of the convergent margin. In the plateau ~ plume model, plateau accretion causes rapid trench advance. Plate convergence is accommodated by shearing at the base of the plateau a.d.shortening in the overriding plate. The trench migrates around the edge of the plateau a.d.subduction is re-established well behind the trailing edge of the plateau, effectively embedding the plateau into the overriding plate. A slab window forms beneath the accreted plateau a.d.plume material is transferred from the subducting plate to the over- riding plate through the window. In all of the models, the subduction zone maintains a relatively stable configuration away from the buoyancy anomalies within the downgoing plate. The models provide a.d.namic context for plateau a.d.plume accretion in Phanerozoic accretionary orogenic systems such as the East China Orogen a.d.the Central Asian Orogen （Altiads）, which ar

In Senegal, few studies have been devoted to non-Hodgkin’s lymphoma. We conducted a retrospective descriptive study of 73 cases treated at the Institut J. Curie Hospital Aristide Le dantec for non-Hodgkin’s lymphomas from 2001 to 2007. The main objective was to determine the clinical a.d.therapeutic aspects. Our population consisted of 39 men a.d.34 women (sex ratio: 1.14). The average age was 36 years with extremes of 5 a.d.76 years. The most common locations were cervical (30.6%) a.d.oropharynx (8.21%). Multiple locations were found in 30.6% of cases. Only 54.4% have histological exam. Patients were managed on cytology basis 42.6% of cases. Histology was performed in 39 patients (54.4%). Among these patients, 69% had aggressive lymphoma, of which 12.82% had a large B-cell lymphoma among indolent lymphomas (59%). The small cleaved cell lymphoma was most often found with 78.26% of cases. The patients were staged with insufficient tools. The protocol most often used was CHOP (64.3%). The most common complications reported were gastrointestinal (11%) followed by skin complications (8.2%). Radiotherapy was performed for 6 patients or 8.2% of cases. Therapeutic strategy was most often used as chemotherapy alone (69.9%). The median duration of follow-up is 18 months.

This document deals with the thermal characterization of a building with a layer of straw above the high floor. In the current environmental context, in Senegal, buildings are the biggest consumers of energy. This is due to the construction materials used. Almost of buildings in Senegal used concrete (cement + aggregates) as based material construction. due to this, the buildings require air conditioning or artificial ventilation to ensure minimum comfort. In face of this situation, it becomes useful to propose methods for reducing this high energy consumption. In this work, we propose to a.d.a layer of straw above the high floor of a building in Matam city (North Senegal). In this case, we designed a.d.modeled one building of single room in which the walls are in briks a.d.a concrete slab. A bale of straw is layered on this slab in order to determine its influence on the energy consumption of the building. This study shows that the straw has a strong influence on the energy consumption of a building a.d.the slab + straw building is more energy efficient than the bare slab building.
