The Congolese State provides 435 million dollars for the effective relaunch of mining activities at MIBA. The investment of these millions of dollars is spread over 5 years, including 161 million for the first two years of the five-year term and the difference in the next three years. While waiting for the first installment of the investment budget, MIBA intends to timidly start mining the kimberlite from the Massif 1 site in the first two years of the five-year term. This kimberlite will be fed to the three processing plants to be operationalized sequentially, and having a CUP of 0.49. Based on the CUP of the factories and the fleet of available machines, we have sized the machine park for the partial relaunch of mining activities. This machine park will consist of 2 probes, 3 excavators, 2 loaders, 6 trucks, 1 dozer, 1 grader, 1 compactor, 200-meter-long piping in place of a tanker truck, a machine refueling pump on site, movable on board a vehicle and safety equipment.

The objective of this research is to analyze the spatio-temporal characteristics of the rainy-agricultural season March-April-May (MAM) in the Republic of Congo (1951-2010). Two methods were chosen using daily precipitation, namely: agronomic criteria and frequencies. The main results show an instability in the start and end dates of the season, the shortening of its length and a dominance of dry episodes, in this case those of 2 to 5 days within all synoptic stations studied. It is found that latitude is the most determining parameter for the distribution of the start dates of the rainy-agricultural season. This evolves according to the South-North gradient.

The new technologies of information and communication (NTIC) know, since decades, a fast development. The sector of health, in particular, saw to increase of very numerous applications. The notification by sms, television-medicine, television-diagnostic, telemonitoring, modify in depth the medical practices and the relation between the practitioner and his/her/its patient. Of what precedes, the application that we put in place has like elements of the bases to digest the conservation of the information of patients efficiently and to facilitate the access of it but also to permit a follow-up of the patients of chronic illnesses with a system of notification by SMS. We had for main objective to help the clinic to solve his/her/its problem of management of follow-up of patients any. The points summarize the gotten results below: We proposed some forms for the harvest of the relative data to the patients, personal, consultation, treatment, and to the medical prescriptions that will be the subject of notification then to the patients by the physicians. These forms replace the pre-printed matters cards of the former system validly; Does our application permit? the user to modify, to suppress and to search for the information easily; We proposed an algorithm of the opening of the session that allows the accés solely to functionalities of basis of the system if one authenticate itself/themselves in order to guarantee the security and the confidentiality of the information.

Computer simulation offers several advantages for electricity learning, such as visualization and interactivity. Computer simulation enables learners to interactively understand electrical phenomena by visualizing them. As a result, abstract concepts become easier for students to grasp. This study aims to determine the impact of computer simulation on students’ understanding of electricity concepts at the Higher Institute of Applied Techniques (ISTA). To achieve this objective, we employed the ‘Circuit Wizard’ software, which was tested with 65 students randomly divided into two groups: a control group (n=30) and an experimental group (n=35), both supervised by four experienced instructors. Prior to the start of their respective courses, a pre-test was administered to each group of students. After the course period, they underwent a post-test to assess their knowledge acquisition. The first group followed the traditional approach to electric circuit learning. The second group, however, underwent the same course but with the ‘Circuit Wizard’ simulator. Data were collected using questionnaires and tests, which were analyzed using SPSS software. The results obtained from the Wilcoxon test, as well as the calculation of normalized learning gains for both groups, indicated a better improvement in terms of conceptual comprehension rate among students in the experimental group during the post-test (Normalized gain is 0,81 for the experimental group and 0,39 for the control group). As evidenced by the results of the Wilcoxon test, this improvement is statistically significant with p < 0.05 for both groups, meaning the p-value is 0.000 for each of the two groups. Consequently, we concluded that the use of computer simulation, such as ‘Circuit Wizard, ’ in physics teaching-learning enables a better understanding of electricity concepts compared to the traditional approach.

Because of the high subscription costs to the distribution network and water bills, access to running water for domestic use remains unaffordable to many inhabitants in cities and villages in the northern regions of Côte d’Ivoire. Thus, borehole and wells water is thus used as alternative to meet daily water needs, most often without a proper knowledge of the quality of such waters. This study aimed at evaluating the microbiological quality of borehole and well water in Ferkessédougou, one of the major cities in north Côte d’Ivoire. Chemical analyses were carried out on water sampled from 7 wells and 3 boreholes randomly selected across the study area. The results indicated that the average static level of the wells ranged from 0.5 m to 7.0 m. Water pHs were acidic to neutral and varied between 5.1 and 6.9. Faecal coliforms, Escherichia coli and intestinal enterococci were the main bacteria found in wells water, with proportions ranging between 2100 and 19000 CFU/100 ml, 120 and 5200 CFU/100 ml, and 30 and 240 CFU/100 ml, respectively. Only one borehole reported the presence of faecal coliforms (150 CFU/100 ml) and E. coli (15 CFU/100 ml). This faecal water pollution highlighted the poor sanitation conditions and unsuitability of water sourced from boreholes and wells to human consumption, indicating the need for adequate treatment of water prior to its use to avoid public health issues.

Loxoscelism is a medical condition due to bites and envinemation by recluse spiders of the genus Loxosceles that may be the cause of polymorphus skin or visceral manifestations up to shock, coma, and death. General practitioners know very little about this condition, which is why it is important to highlight it in order to plan appropriate treatment and prevent complications. Case report: This report is related to a 2-year-old infant female who is admitted to the emergency room with a large, red, and painful lower limb against a backdrop of fever due to the bite of a spider 48 hours before. Conclusion: Cutaneous oxoscelism is a poorly diagnosed condition. As identification of the spider is not always possible, the diagnosis must then be made on the basis of epidemiological, clinical, and biological evidence after eliminating other causes in order to prescribe appropriate treatment.
