Aim: To evaluate results of cataract surgery in Eye Camp in rural areas. Patients and Method: This study set about the retrospective analysis of cases and operating reports of patients over the age of 10, operated for cataract in Eye Camp and fixed strategy from January, 2010 to December, 2012. Postoperative data were specified and compared. Results: Out of a total of 1145 patients operated, 577 (50.40%) were men compared with 568 (49.60%) women. The general mean age was 62 years, similar in Eye Camp and in fixed strategy. Sixty percent of patients were operated in Eye Camp. After 4 weeks of follow-up, 77% of patients were met again, and 83% among them showed good results (corrected visual acuity = 3/10). This rate of good results was 80.43% in Eye Camp against 87.7% in fixed strategy. We noted 18.25% of complications among which 11.25% were in Eye Camp. The functional outcomes of both strategies get closer to WHO standards. Conclusion: Eye Camp in the Central Region of Togo is an interesting alternative that contributes to the fight against blindness, even if postoperative follow-up is still to be improved.

Venturi scrubbers are usually used for large particles cleaning in turbulent gaseous flow. In this work, submicron particles scrubbing in laminar forced convection dusty air flow in a rectangular venturi scrubber have been numerically simulated. Hydrodynamics effects and scrubbing process are investigated in detail. Results are presented as flow velocity, axial pressure, streamlines pattern, particles and droplets mass fraction profile, and collect efficiency. They show that venturi scrubbers can be efficient for submicron particles scrubbing. In fact, a better collect efficiency is obtained at high particles-droplets residence time, high ratio droplets concentration/particles concentration, low venturi diameter ratioand low Reynolds numbers. There is a critical Reynolds number value for which the collect efficiency becomes very low and tends to be constant.

Background: Large papillary excavations constitute a true differential diagnosis of glaucoma in our environments. Aim: To present a clinical case of large papillary excavation simulating glaucomatous optic neuropathy in a young subject. Case Presentation: The ophthalmologic examination made it possible to note a visual acuity of LogMar 0.00, ocular hypertonia and a large papillary excavation in both eyes. The visual field noted bilateral perimetric involvement suggesting optic neuropathy. Optical coherence tomography (OCT) of the ganglion complex revealed an absence of involvement of the ganglion complex and the ganglion ridge essential to evoke optic neuropathy. An ocular hypotonizing treatment made it possible to normalize the intraocular pressure. Conclusion: The particularity of this observation lies in the fact that the perimeter involvement that preceded any involvement can simulate a glaucomatous involvement. Functional damage to the visual field must be correlated with structural damage to suggest glaucomatous damage in our ophthalmic patients.

Mixed convection of heat and mass transfer in an isosceles trapezoidal cavity has been studied numerically. Constant heat flux is imposed through four outlets and the grid is insulated. The inclined walls are maintained in natural convection while the lower horizontal wall is adiabatic. These conditions reflect the air draft zone of the ASUTO charcoal stove. The governing two-di- mensional flow equations have been solved by using the finite difference method and Thomas’s algorithm. The investigations are conducted for different values of Richardson (Ri), Reynolds number (Re) and inclination angles of sidewalls. The results are presented in terms of streamlines, isotherms, moisture contours. It was found that for Reynolds number (Re) equal to 100, the flow pattern is strongly dependent on the inclination angle and Richardson number. Thus, for high Richardson number (Ri) values (10, 100), the dominance of natural convection over the flow structure decreases with the decreasing of the inclination angle of sidewalls of the cavity. For Ri = 1, an optimum air draft corresponds to an inclination angle in the vicinity of 22° while for Ri = 10 or 100 (in dominance of natural convection), the optimum inclination angle for air draft is in the vicinity of 15°.

We present a careful quantitative description of land use in central Togo, by constructing farm budgets and analyzing time series data on agricultural production in four prefectures over the time period from 1996 to 2015. One key finding is that higher prices for chemical inputs are associated with more deforestation (as proxied by area in yam production), and correspondingly, greater quantities of chemical inputs applied are associated with less deforestation. This confirms that chemical fertilizers and forest clearing are substitutes and suggests that one path to reducing deforestation is to increase agricultural productivity, and to provide farmer with agricultural risk assistance that covers the farming negative externality costs. This risk assistance may include the coverage for the environmental deterioration costs, and the subsidies to compensate for investments’ cost.
