Abstract: Adoption of technologies is vital to sustainable livelihood and socioeconomic development of rural households. The level of Adoption of introduced climate change adaptation strategies in Kishi, Oyo State, Nigeria was assessed in this study. The study also investigated the factors influencing the adoption rate of the technologies with a view to identify the constraints vis-a-vis suggesting solutions for improving adoption. In an attempt to carry out the said objective, data were obtained through a structured questionnaire administered to 500 farmers within the study area. Descriptive statistics and multinational logit model were used to present the data and analyse the results. Result shows that gender, age educational level, number of plots access to extension services and credit facilities affect the adaptation rate of farmers to the technologies. Non adequate provision of extension services for follow-up activities may have accounted for the low adoption of the technologies. Therefore, for improved rate of adoption of technologies by farmers, agricultural extension services must be provided. Farmers are also encouraged to join farmers group for improved delivery of services by extension agents. Adequate provision of credit facilities must be provided relevant stakeholders and policy makers, targeting literate farmers, who are the major adopters of disseminated technologies for improved and sustainable food production.

Abstract: Côte d'Ivoire has, in order to diversify its economic resources, decided to exploit its mineral reserves. Industrial gold mining in Côte d'Ivoire began in 1991 with the opening of the Ity gold mine in the department of Zouan-Hounien, in the west of the country. Several regions of the country have seen mines open. In the Loh-Djiboua region, in the department of Divo, Hiré gold mine opened in 2013. Mine operations consist of mechanical extraction for oxidized ore but also blasting for sulfired ore. Mining operations are then supposed to take place at a minimum distance of five hundred meters from the first dwellings. From the results of the research work, the mining company requests and obtains in 2017, from the State of Côte d'Ivoire, the extension of its operations, in the direction of the city of Hiré, with the possibility of making blast at two hundred and fifty meters from the first dwellings, posing the problem of the proximity of mining blast to the dwellings. The situation appears unprecedented in the mining sector of Côte d'Ivoire. Blast is a source of nuisance, including vibrations. Our study focused on the prediction of vibrations related to shots. Our method of study consisted in first determining, from the formula of Oriard, the constants of the site and to predict from them, the vibrations generated by the explosive blast.

Abstract: Activated carbon, which is used in many application areas such as gas purification, purification of pollution in water and wastewater, removal of odor and pollution, in the defense industry, in the production of protective clothing and in the health sector, was produced from solid products obtained by waste polyethylene terephthalate (wPET) liquefaction that was carried out under non-catalytic conditions, the reaction time of 15-90 min, and a reaction temperature of 325-425 °C in a batch reactor. The solid products obtained, after grinding, were made in a muffle furnace at 400-700°C in a nitrogen gas atmosphere for 30 min. The solid products obtained in the liquefaction of waste polyethylene terephthalate contain approximately 60% Carbon (C), 4% Hydrogen (H) and 36% Oxygen (O), and are composed of terephthalic acid (C8H6O4) in crystalline form. According to Brunauer–Emmett–Teller (BET) analysis, BET surface area of 313.05 m2g-1 and average pore diameter of 2.71 nm of ZnCl2 activated carbons were obtained. They have formed largely mesoporous structures. According to Scanning Electron Microscopy (SEM) analysis, it was observed that medium and large porous structures were formed. Produced activated carbons have commercial product potential but there is a need to optimize the process parameters for better results.
