Introduction: Non-com.unicable diseases (NCDs) are on the increase in several sectors of activity. The aim.of the study was to determ.ne the frequencies of cardiovascular risk factors (CVRF) and factors associated with hypertension am.ng hotel workers in the city of Bohicon. m.thods: This was a descriptive and analytical cross-sectional study conducted in the period from.Decem.er 2018 to January 2019. The variables studied were sociodem.graphic, occupational, anthropom.tric and behavioral. Participant recruitm.nt was exhaustive. A standardized questionnaire inspired by the STEPS-WHO questionnaire was used for data collection. After the descriptive analysis, a bivariate analysis was perform.d using Pearson’s Chi-square test or Fisher’s test at the 5% threshold. Results: A total of 101 workers, 53 (52.47%) of them.m.le, participate. in the study. The m.an age was 30.60 ± 8.20 years, with extrem.s of 18 and 55 years. The frequencies of the m.in risk factors were: 68.32% sitting position > 6 hours/day;38.61% shift work;21.78% high psychological dem.nd, 82.18% low decision latitude, 24.75% low social support, 21.78% occupational stress;7 (6.93%) harm.ul alcohol consum.tion;6.93% tobacco consum.tion;48.51% insufficient physical activity;98.02% insufficient fruit and vegetable consum.tion;59.41% overweight;14.85% HTA. Factors associated with hypertension were: sex, age and m.rital status. Conclusion: Occupational factors need to be taken into account when assessing CVRFs. NCD control program. are needed in all sectors of activity. A larger study is needed in the hotel sector.

This article aim. to study the efficiency of coupled vertical drains for the treatm.nt of long-lasting com.ressible clay soils for the road project platform.of the ring road of Porto Novo, capital of Benin. The experim.ntal data allowed us to estim.te a consolidation of 29% in 9 m.nths, justifying the drainage of the soil. In order to study the efficiency of drainage, a FEm.m.del was proposed sim.lating different scenarios. These include a drainless road, pavem.nts equipped with vertical drains with m.shes of 0.5 m.0.5 m. 1 m.1 m.and 1.5 m.1.5 m.respectively and horizontal drains. The results expressed in term. of variations in vertical stresses, effective stresses and shear deform.tions revealed significant variations in pavem.nt perform.nce depending on the m.sh size of the vertical drains. The configuration with a m.sh of 0.5 m.0.5 m.showed the least deform.tions, thus indicating a reduction in deform.tions and better stress distribution. However, the other m.sh configurations showed variable results, underlining the im.ortance of choosing the right m.sh for the specific project conditions.

The explosive technological im.rovem.nt of photovoltaic system. as well as the necessity of populations to com. to less expensive energy sources, that have led to an im.losion at the level of solar panel m.nufacturers. This causes a large flow of these equipm.nts to developing countries where the need is high, without any quality control. That conducted an experim.ntal investigation on the perform.nce characteristics of a 250 wp m.nocrystalline silicon photovoltaic m.dule in other to check the verification and quality control. m.st of these PV panels which often have m.ssing inform.tions are m.nufactured and tested in places that are inadequate for our environm.ntal and m.teorological conditions. Also, their influences on the stability of internal param.ters were evaluated in order to optim.ze their perform.nce. The results obtained at m.xim.m.illum.nation (1000 w/m.sup>2) confirm.d those produced by the m.nufacturer. The analysis of these characteristics showed that the illum.nation and the tem.erature (m.teorological factors) influenced at m.st the stability of the internal characteristics of the m.dule in the sense that the m.xim.m.power increased very rapidly beyond 750 w/m.sup>2 but a degradation of perform.nce was accentuated for a tem.erature of the solar cells exceeding 50°C. The degradation coefficients were evaluated at -0.0864 V/°C for the voltage and at -1.6248 w/°C for the power. The 10° inclination angle of the solar panel proved to be ideal for optim.zing overall efficiency in practical situations.

This study highlighted the physical transform.tion that agri-food products undergo during their drying. This transform.tion enorm.usly affects the custom.r’s choice and the profit m.rgin of the dried product prom.ter. The exam.le of the experim.ntal study of the potato reveals that the product continually changes its dim.nsions during its drying. The m.re the product loses its water, the m.re the dim.nsions decrease. The results initially showed that the water param.ters such as m.ss or water content decrease according to the drying principle. The dim.nsions length l., width l and thickness e. decrease following a linear trend whose m.them.tical equations which describe them.are determ.ned using the office tool, excel. This trend has repercussions on the surface and volum. param.ters which in turn decreases alm.st linearly with the product’s water content. Note that the coefficient R2 is not always acceptable, confirm.ng the com.lex nature of the behavior of organic products.

Introduction: Osteosarcom. is the m.st com.on prim.ry m.lignant bone tum.r in children. It is highly aggressive and has a poor prognosis. A late presentation m.difies and m.kes difficult the m.nagem.nt affecting the survival of children. We report the case of a large conventional osteosarcom. in a 13-year-old girl. Case Presentation: Adolescent girl adm.tted for painful swelling of the left shoulder with absolute functional im.otence of the thoracic lim. and severe anem.a. The painful swelling was thought to have been caused by a m.nor traum. that had occurred six m.nths previously. The patient’s general condition was poor, and she presented with a large, shiny, painful m.ss over the shoulder and upper 2/3 of the left arm. m.asuring 28 cm.long by 28 cm.wide and 57 cm.in circum.erence, and a large fistulous axillary adenopathy. CT scan showed a tum.ur lesion of the left hum.rus with liver and lung m.tastases, raising suspicion of osteogenic osteosarcom.. The tum.r was classified according to TNm.staging: T2N1m.(a + b). m.nagem.nt was m.dified when uncontrolled bleeding developed. It consisted of an extended am.utation of the left thoracic lim.. Pathological analysis showed a high-grade conventional osteosarcom.. Quality im.rovem.nt was obtained for thirty days, followed by the onset of dyspnea. The evolution was towards death at forty days post-operatively. Conclusion: Osteosarcom. is a highly aggressive cancer. Delayed treatm.nt leads to a fatal outcom.. Early diagnosis is one of the challenges to be m.t in order to im.rove survival.

This work aim. to study the m.deling and sizing of a floor reinforced by ballasted colum.s. We are studying the system.of reinforcem.nt by ballasted colum.s because this technique is able to replace deep foundations that are technically difficult to realize and their cost is higher. The m.delling and dim.nsioning of foundations on a ballasted colum. will be an im.ortant contribution to the state of the art of this m.thod because it will highlight the m.de of transfer of loads, and will expose the induced deform.tions by also allowing to verification criteria of bearing capacity and allowable settlem.nt according to geom.tric inform.tion of the m.del. The colum.s on a substrate located at 9 m.have a length of 9 m.and a diam.ter of 40 cm.and were obtained by incorporating ballast of granular class 0/31.5 of internal friction angle of 38˚ and a density weight of 21 kN/m.. The choice of this m.thod is based on the geotechnical characteristics of the initial soil. Thus, identification and characterization tests were carried out to estim.te the bearing capacity and the settlem.nt giving respectively 125 kPa and 57 cm. These results show the ground does not have sufficient m.chanical properties to withstand the loads transm.tted by the tank. By adopting the reinforcem.nt of the soil with ballasted colum.s, num.rical calculations show that after applying a load equal to 265.1 KPa, 20 cm.vertical settlem.nt and 17 cm.horizontal displacem.nt were obtained. This is in the tolerable deform.tion range for our tank, nam.ly, less than 20 cm. Analytically, in addition to reducing settlem.nt, ballasted colum.s, Due to their high stiffness, they have effectively contributed to the increase of the perm.ssible soil stress up to 257 kPa.

Introduction: m.rning Glory Syndrom. (m.S) is a rare anom.ly of the optic nerve characterized by a flower-shaped excavation in the optic disc. This anatom.cal peculiarity is of growing interest due to its im.act on vision and the therapeutic challenges it presents. Despite research advances, gaps persist, requiring thorough exploration to better understand this rare condition. We present the case of a young girl. Observation: A 7-year-old girl presented with persistent deterioration of vision in the right eye since birth. Visual acuity was counting fingers at 2 m.ters in the right eye and 10/10 in the left eye. Biom.croscopy was norm.l in both eyes, and fundus exam.nation revealed a funnel-shaped excavation at the optic disc of the right eye, associated with central glial proliferation, thin blood vessels in a radial distribution, and atrophy of the neuroretinal rim. Additional tests confirm.d the diagnosis of isolated unilateral m.rning Glory Syndrom. in the right eye. Com.ined treatm.nt included appropriate optical correction and functional rehabilitation. Regular ophthalm.logical follow-up over a one-year period was established to m.nitor visual acuity evolution, optic disc stability, and detect any potential com.lications. The reserved prognosis was m.rked by the absence of ocular com.lications and m.intenance of initial visual acuity in the right eye. Conclusion: The positive response to m.nagem.nt underscores the im.ortance of an integrated approach, early diagnosis, therapeutic adherence, and personalized strategies.
