Back.round: Genetic diversity of human immunodeficiency virus affects the treatment and the emergence of resistance. Some subtypes would develop resistance more frequently than others. The aim of this study is to determine the rate of virological treatment failure and the involvement of genetic diversity and different mutations in this failure in k.nshasa. Methods: Of the 153 Antiretroviral-naive patients who were included in the cohort, 138 patients have been received for the appointment of the 6th month. Clinical parameters were recorded on individual patient charts. The determination of Viral Load (VL) was done at the Laboratory of Molecular Biology. Clinical and biological parameters of the 6th month were compared with those tak.n at baseline of the cohort to determine the evolution of patients under treatment. Results: At the consultation of the 6th month, 138 patients (90.2%) had returned out of the 153 included. Eighty-one (58.7%) patients were women and 57 (41.3%) men. The age of patients is between 18 and 65 with an average of 37 years. Ten deaths (6.5%) and 5 (3.3%) lost have been reported. One hundred twenty-five patients (90.5%) were in clinical stage 3 and 13 (9.5%) in clinical stage 4. The median CD4 T cells is 560 cells mm3. The median VLs of patients was 0.90 log10 RNA copies/ml. Of the 34 patients in virological failure, 8 (23.5%) are minimal failure, 23 (67.7%) in moderate failure and 3 (8.8%) in severe failure. According to the Pearson’s test, VLs at 6th months were highly correlated with that of inclusion, with V75 and k.0 mutations for NRTIs, with V108 mutation for NNRTI well as the virological failure of treatment. Conclusion: Our results confirmed the hypothesis that high Viral Load at the start of the treatment is a poor prognosis for the development of therapy. Transmitted mutations are involved in treatment failure.

UV radiation and ozonation were investigated as disinfection alternatives for the wastewater treatment plant. The inactivation of total and fecal coliforms using ozone and ultraviolet radiation as separate treatments was evaluated. Different ozone concentrations (3 to 40 mg O3/L) were applied and UV fluencies ranging from 8.5 to 12 mJ/cm2 at different pH values (from 5 to 9) were tested. Best results were obtained for ozone doses near 20 mg/min with removals of 72% and 78% of fecal and total coliforms, respectively. The ozone also was capable of oxidizing organic matter in the effluent measured as COD (the highest removal obtained was 36% for 20 mg O3/min). Maximum bacterial resistance was observed at pH 7 in both cases. The UV light offered a high bacterial inactivation (over 80%) and the lowest bacterial inactivation was observed at pH 7. Finally, we obtained the electric energy per order (EEO, k.h/m3/order), defined as the electric energy (k.-h) required to degrade a contaminant by one order of magnitude in a unit volume of contaminated water, being noteworthy that EEO values for the UV process resulted were lower than those determined for the process with ozone in all the water flow tested.

It has been shown that farmers with limited k.owledge of the use and safe handling of pesticides may suffer exposure which results in adverse health effects. In Buea, Cameroon, small-scale tomato farmers commonly use pesticides for pest control. Information was obtained from these tomato farmers to determine the extent and types of their pesticide use, their k.owledge of pesticide use and effectiveness, and their perception of potential harm resulting from pesticide use. A standardized questionnaire, interviews, field observations and an analytical rank.ng game were used to describe the pesticide use of 93 tomato farmers. Many farmers (47.6%) used pyrethiod and organophosphorus insecticides and identified these chemicals as the most effective in pesticide control;these are WHO Class II pesticides which are the most hazardous to humans. Most farmers (83.8%) used k.apsack.sprayers to apply pesticides, with 76.3% using no or partial personal protective equipment (PPE). It was notable that 55.5% of farmers expressed no concern regarding the wind direction (pesticide drift) during spraying. The results showed a significant association between the method of pesticides application and farm size (P k.owledge of the safe and judicious use of pesticides. Strategies that provide training on the appropriate use of pesticides, how to reduce exposure to and health risk. of pesticides and alternative options of pest management and control are required. The study also raised concerns that further control of the sale and distribution of pesticides may be indicated.

In copper sulfide concentrates smelting, the off-gases from the Pierce Smith converter (PSC) furnace must be treated to prevent environmental impacts as they are highly corrosive and toxic. The purpose of this research project is to present a methodology for the simulation of a capture and cooling system of the smelting off-gases from a Pierce Smith copper converter, using computational fluid dynamics. Through this methodology, it is possible to obtain a simulation model of the smelting off-gases behavior with an average error of 9.88%. Basically, it demonstrates that the simulated tendencies of the metallurgical off-gases on the cooling hood and chamber can be reliable to predict the thermo-fluid dynamic behavior of the off-gases inside the studied off-gases handling system.
