In the district of Ndikiniméki, many primary school students are unable to complete their primary cycle and obtain their CEP. They drop out very early and abandon their studies early. To this end, the question we asked ourselves is the following: is there a link between socio-cultural factors and the early school leaving of primary school students in the locality of Ndikiniméki? This being said, we wanted to verify the hypothesis that there is a link between sociocultural factors and early school leaving among primary school students in the Ndikiniméki district. Our study allows us to note that there is a link between the socio-economic level of the family and early school leaving and that there is a link between family cultural capital and early school leaving.

Introduction: The coronavirus of Severe Acute Respiratory Syndrome 2 was discovered in 2019 in the city of Wuhan, China. The preliminary reproduction rate of SARS-CoV-2 was estimated to be between 1. 4 and 2. 5 by WHO on 23 January 2020. Senegal has positioned itself among the countries most affected by the pandemic in Africa. Strategies for the response to the COVID-19 epidemic have been put in place to ensure an operational and effective response in Dakar and the provinces. The overall objective of this study is to analyse the epidemiological evolution of new confirmed cases of Covid-19 in Senegal in 2020. Methodology: This was a time series analysis of Covid-19 during the period from March 02 to August 31, 2020. The study population was people tested by RT-PCR for covid-19. The data was aggregated from the publications of the Ministry of Health on the Covid-19 Senegal site and from the WHO. The data collected was analyzed using R software, for description and modeling with ARIMA and Prophet. Results: This study showed that the total number of Covid-19 cases recorded during the period studied was 13,611, a median of 3,740 was recorded on June 1, 2020; on average, 4810 cases were registered. New confirmed cases had a median of 79 and an average of 73.9 new cases recorded. On average 3050 cured cases were recorded with a median of 1860. On average 3940 cases were transmitted locally. March recorded the highest positivity rate at 13.56% with a sharp decline to 8.49% in August. An attack rate of 1.05 per 100,000 populations was recorded in March, this rate reached 20.98 in August. The reproduction rate was at 1.96 at the start of the state of emergency on March 23, 2020; this rate increased to 1.11 at the end of our study, on August 31, 2020. Conclusion: The predicted and actual data had shown an upward record of new confirmed cases at the end of 2020. But the data may change in reality due to some changes. In the absence of change, despite the measures put in place, the hope is that the vaccine can provide a solution.

The efforts that have been made in Morocco within the framework of the Emergence Plan and the National Pact for Industrial Emergence are worth noting given the dynamics that have been triggered, and the measures brought by these plans to Moroccan industry, namely the approach to approach to Morocco’s Global Trade. However, the analysis of competitiveness that we implemented during the period 2005-2014 shows that this relates to a few sectors (automobiles and aeronautics) and this was not the case for others: industrial sectors. However, the results obtained from the analysis of the main competitiveness indicators of these sectors reveal mixed performance of the industrial sectors. This also confirms that the measures adopted did not generate the expected effects, particularly in the implementation of a sustainable and efficient industrial development model capable of contributing effectively to improving the international competitiveness of Morocco such as sustained performance achieved by countries which were at the same industrial development level as that of our country. It is therefore necessary to question the determinants of this low competitiveness of the industry.

This research work focuses on the redox map of the Akola West sector. In the Akola sector of Arlit, uranium mineralization is hosted by the Guezouman, an originally reduced sedimentary formation. The presence of oxyhydroxides in this formation in the Akola West sector bears witness to the circulation of oxidized fluids. Mapping the distribution of the various redox parameters revealed the existence of redox fronts. Analysis and interpretation of these results also revealed the factors that controlled mineralization in the Akola West sector. These include tectonic, lithostratigraphic, paleogeographic, redox facies and fluid flow. To this end, a fluid flow hypothesis has been proposed for this sector.

A «Computer Obscurantism» hovered dangerously on applications in Computer Sciences in the domain of networks and telecommunications in Africa, specially in Democratic Republic of Congo. The using of extrinsic methods to Computer Sciences sake in majority events the realization of prevaricated results. Inclined by the desire to see the Computer Sciences be really vehicled in their Africa’s quintessence in general manner and specifically in Democratic Republic of Congo, we have chosen to redact this article which is about the «Conceptual Approach of Technique System», gage of the emergency of a good economy based on local talents and no comes from the stranger. The choice is taken from the Structured Analysis Design Technique method for the case of application «Unified Computing System». It’s about on this example to present the conception’s steps for the system integration of unified Informatics Cisco in the network answering to the principle disponibility; That’s to say, predict the rendonduncy of interconnexion equipments and to separate the traffics by the creation of the network segments vituals privy. Design’s tool: Edraw Max.

The present study was carried out to improve knowledge on the preferential environments for invasion of C. odorata with a view to combating the species. Four biotopes were selected: closed forests, ruderal areas without C. odorata (by the side of roads, under wires), ruderal areas with a young invasion of C. odorata (populations invaded by young C. odorata plants) of less than one year and ruderal areas with an old invasion of C. odorata (populations invaded by C. odorata plants with lignified stems, well-developed and massive shrubs) from one to three years. Floristic inventories and soil samples from 0 to 20 cm depth were carried out in quadrats of 4 m2 (2 m × 2 m). A total of 36 quadrats were placed using 9 repetitions per biotope. A morpho-pedological description of the BNP soils according to the toposequence was also carried out. The results showed that theBNP soils belong to the class of ferrallitic soils or Ferralsols. The summits are not preferential growth environments for C. odorata. The species adapts with difficulty to this type of environment. Mid-slopes are environments where we can observe the growth of C. odorata. The species manages to adapt to this type of environment. Finally, the bottom of slopes are preferential environments for the growth and proliferation of C. odorata. The species grows easily, proliferates and even becomes invasive.

The Sassandra-Cavally (SASCA) domain (SW Côte d’Ivoire) marks the transition between the Archean Kenema-Man craton and the Paleoproterozoic Baoulé-Mossi domain. The methodology applied to study the rocks of the Soubré area considers both field and laboratory work. The Soubré area of the SASCA domain is characterized by migmatitic gneisses, metagranites and garnet micaschists. Migmatitic gneisses are composed of quartz, feldspar, biotite, chlorite, muscovite and opaque minerals, with occasional amphibole rods. Metgranites, on the other hand, are composed of quartz, feldspars such as plagioclase and microcline, biotite, accessory minerals and opaque minerals. Garnet-bearing micaschists are composed of quartz, biotite, muscovite, garnet, plagioclase with accessory and opaque minerals. Structural observations in the Soubré area reveal a first foliation (S1) trending NW-SE, dipping between 40° and 85° towards SW and associated with a N080-trending shear with a sinistral component, as well as folds whose axial planes are parallel to S1. This first foliation is intersected by a second (S2) trending NE-SW with dips of 60-85° either towards NW or SE. The S2 foliation is associated with a N166 shear with a sinistral component and folds whose axial planes are parallel to S2. All these structural observations in the Soubré sector would be compatible with the structures observed in the SASCA domain on the coast from Grand-Béréby to Tabou.

Introduction: The COVID-19 pandemic is an unprecedented global situation, which has turned all systems (economic, political, social, and health) upside down. It has paved the way for psychological and psychosocial morbidity among the public and healthcare professionals both directly and indirectly involved in the response. Objective: The aim of this study was to identify the difficulties associated with the psychosocial experience of COVID-19 among a population of healthcare professionals. Method: A qualitative, cross-sectional descriptive study of a population of healthcare professionals who had used a listening and support line was conducted in Dakar from May 2020 to July 2020. Results: A total of 236 calls were received by the hotline, of which 20 were from healthcare professionals, representing a rate of 8.5%. 08 calls were received from female healthcare professionals, representing a rate of 40% of the total study population. According to healthcare professionals, the most common themes were emotional difficulties, family difficulties, work overload, and lack of support from superiors. Discussion: At the end of our work, we noted that the mental health of health professionals deserves special attention for early detection of COVID-19 psychopathological disorders. Thus, it is important to systematically institute support structures for healthcare professionals when responding to health emergencies.

We want to supply electrical energy to a science with a required power of 110 KW using a micro thermal steam power plant, using wood chips as fuel. The goal here is the recovery of waste and the various means of producing electrical energy. We are in the logic of local and decentralized production.

A fire is a large fire that spreads causing significant damage. It is considered one of the disasters that affects public infrastructure. In fact, the MLDK market in the municipality of Masina has experienced cases of fire of unidentified origin that have caused huge losses to small traders and even, caused huge expenses of rehabilitation work for the state and some pavilions have remained unrehabilitated to this day. The objective of this article is to set up a fire detection and extinguishing system equipped with networks, thermal sensors and sprinklers to prevent fires in order to protect people and their property. In addition to the literature review, which is upstream of all the methods used, this approach was based on direct observation and experimental methods supported by a field survey. The results obtained show the interest of this project on fire detection, especially in non-working hours. Automatic fire detection and extinguishing is a very complex and delicate process, which requires appropriate and efficient equipment.

At the end of our study, it should be remembered that our ambition was to evaluate the financial management autonomy of Performance-Based Financing, then see the reasons and remedies to propose for the improvement of the services offered to the ‘HGR Gemena. In carrying out this work, our main objective is to evaluate the level of management autonomy of the HGR/Gemena in the performance-based financing approach. Through this evaluation, this study will explain the mechanisms likely to guide this institution towards the performance so desired in the Performance-Based Financing approach. To carry out this study, we used the descriptive and documentary method, supported by observation and documentary review for this study it is based on the autonomy of financial management, to collect data on the variables of the study, namely: Human resources management, Material management, Financial management, MEG management and other inputs, Flat rate pricing. To achieve these objectives, it was useful for us to use different techniques to collect data and information, including the documentary review. In the data analysis the following methods were used analytical methods, structural-functionalist method, statistical and dialectical method. Indeed, the results of the present study reveal that the contribution of Performance-Based Financing to the financial management autonomy of the HGR/Gemena takes into account distribution keys in relation to the contract signed by the EUP: drug purchase, performance bonus, investment, operation, social marketing and bank reserve which led to the financial management autonomy of the HGR/Gemena.

Stomachs of 852 individuals of Zanobatus schoenleinii were sampled at three fishing stations located in the Dakar peninsula to determine diet composition. Three indices (If, Cn and Cp) were used to determine prey occurrence. A feeding coefficient (Q) was used to classify prey into different categories and define the feeding strategy of the species. The results showed a high vacuity in the species, which is thought to be related to the maturation of the gonads and digestion ongoing after the capture of the animal. The food spectrum consisted of nine prey groups including crustaceans especially shrimps which were preferential prey in both cold (Q= 628.31) and warm seasons (Q= 1067.60) and annelids of the genus Nereis as secondary prey during both seasons. Other prey groups such as fish and mollusks were incidental. Comparisons between individuals of different sex, size and fishing area indicated an absence of sexual segregation due to similarities between the diets of males and females. On the other hand, differences between young and adult individuals would indicate a distinct spatial distribution between individuals of different size. With respect to the landing stations, the differences noted between Soumbédioune/Ouakam and Hann allowed to affirm that although the tiger ray feeds selectively on typical prey, it has the capacity to adapt its diet in response to variations in prey availability.
