Ahouansou Pages: 26 - 34 Abstract: The predominance of the primary sector is noticeable in the economy of most African countries, particularly in Benin. Thus, to make this sector a vector of wealth and development, it is imperative to think about the development of technologies to improve the efficiency of processing and product quality. The mechanization of this sector is therefore necessary to make it more competitive. In Benin we have a lot of products which are made with the coconut. This sector has been relegated to a non-priority plan, whereas the coconut palm is a plant with a very considerable value like the oil palm, of which all the derived products are usable. It seems necessary to pass to the revival of this sector to help to stabilize the incomes of the small producers and traders in particular and to improve the commercial balance of the country in general. The maximization of the output of this sector directs towards the formula of Lavoisier: "nothing is lost, nothing is created, everything is transformed". The application of this formula allows us to transform the by-products of the said product. Currently, the de-shearing of the coconut is done manually with a cutter or with a pointed object. This way of making is too painful for producers who have large exploitations of coconut trees. In order to make this sector more profitable, our end-of-training work focuses on the study and design of a coconut de-sheathing machine intended to accompany coconut producers by reducing their pains and increasing their productivity in order to enhance the transformation of the said product.

Massou Pages: 35 - 43 Abstract: In this paper, study of the impact of a new treatment approach in the aggregation kinetics of deoxy-hemoglobin S molecules is developed. New approach exploring mathematical model of dielectric permittivity of Davidson-Cole and takes into account several relaxation times of the dielectrics substances like blood. Results are such that, (i) only a fine analysis of intrinsic energy dissipation curves allow sufficient precision to be obtained to describe chronic hemolytic anemia due to sickle cell anemia based on the frequency of relaxation, (ii) hematocrit calculation by the formula allowed to show the uniqueness of the relaxation time of deoxy-hemoglobin S, (iii) hematocrit levels are low and the dispersion coefficient is the parameter most influential in the aggregation of hemoglobin S. From the analysis of all these results, it appears that, the mathematical model of Davidson-Cole is a good model interpretation and knowledge of sickle cell disease. The interest of this work is the understanding of the molecular mechanism that can help develop new treatment approaches capable of preventing or limiting the risk of complications of red blood cell diseases.

Therefore, interviews were carried out in February, March and July 2021, within the fishers´ community, at dockside and marketplaces. The results indicated that the fishing sector generated a large number of professionals (250 respondents, of whom 76 men and 174 women) who were associated with fifteen types of jobs listed among managers appointed by the Government and privately employed professionals. In addition, socio-economic characteristics that were focused on indicated that the highest percentage of active persons (38.4%) was recorded within the age bracket of 35-45. More than half of respondents had no schooling. Tunas and other species landed, depending on fishing seasons, made up a large part of the fish consumed. Daily fish-consumption varied depending on household numbers, with consumption between 1.0 and 1.5 Kg/d or 2.0 and 2.5 Kg/d being the commonest. This study really shows that the local fishery is of vital importance to the whole community. PubDate: 2022-08-27 DOI: 10.14419/ijbas.v11i2.32078 Issue No:Vol. 11, No. 2 (2022)
