With the advent of automatic learning methods and the exponential growth of computer power, several things are being facilitated, in particular the prediction of certain behaviors, made by banking establishments. Although some prediction tools such as Excel are nowadays used by some of our establishments, we find that machine learning remains unused so far, even less with all its power, yet many advantages and opportunities present themselves to it. use. We argue that elsewhere, experiments based on machine learning, in other words automatic learning, are more than topical, even more so in the banking sector. We are therefore going through this experience, to propose as an illustration and educational, for our local banking establishments, an activity of prediction of monetary inflation, using the power of artificial intelligence. The prediction in question here will be made on the basis of a set of data collected from a few banks in the city-province of Kinshasa, and particular emphasis will be placed on general consumer price indices. It is important to note that the prediction in question here goes as far as clearly specifying the causes of the inflation being analyzed, or predicted, of course on the basis of the different variations of the indicators. The machine learning used here offers us several possibilities in terms of algorithms and models, but in the context of this work, we will only address a few, in particular Linear Regression, the Random Forest Regression algorithm or Radom Forest Regression, and the Regression model decision tree, will get we will get the best algorithm with respect to its score.

The present study aims to improve knowledge of the resilience of post-cultivation vegetation in the Ivorian sub-Sudanese sector by discriminating the stages of post-cultivation reconstitution and characterising these stages using the structural attributes and functional traits of the species. To this end, 4 groups corresponding to the different stages of reconstitution were identified. These stages are divided into three groups according to their characteristics. Stage_1 is characterised by SudanoZambézian (SZ) and introduced (i) species, generally hemicryptophyte-pyrophytic and chamaephytes that spread by anemochory and barochory. Stage_2 is characterised by Guinean-Congolian and Sudano-Zambézian transition species and Sudano-Zambézian species. They are therophytes and nanophanerophytes, anemochores with small leaves (nanophyll, leptophyll and microphyll). Stages 3 and 4 share the same characteristics. They are characterised by GC species, which are generally large (mesophanerophytes and megaphanerophytes) as well as geophytes, which have large leaves (megaphyll) and spread by zoochory (epizoochory and endozoochory). In short, post-cultivation reconstitution takes place in four stages. These stages are divided into four groups according to their characteristics. Depending on the maturity gradient, these stages are marked by a transition from savannah species, herbaceous species with small leaves and anemochorous spread, to forest species, large species with large leaves and zoochorous spread.

This research focuses on the determining the effects of social prestations of the National Savings loan of Social Security (NSSS) on the social and economic life of the beneficiaries in Bukavu. It uses the primary data collected on 138 persons by using a quantitative investigation questionnary. The methodology adopte dis analytic, using the descriptive purely statistics obtened by the SPSS 20.0 logicial. The results of this study indicate that the social prestations of the NSSS have positive effects on the social life of beneficiaries, but not on their economic life, because of the modicity of the amount received, sometimes by irregular periods. The conclusion of this paper calls out the government to diversify the social security organisations and to improve the social prestation amount for the beneficiaries (social prestatories) so that their well-being should grow.

Numerous studies have shown the variability of the physico-chemical and microbiological characteristics of meteorite waters collected and stored in recovery tanks. This variability can have negative impacts for users, physico-chemical and microbiological analyzes reflecting the quality of rainwater collected downstream from the roof and stored in a concrete tank were carried out. The chosen site is a rainwater tank whose use is not limited to laundry, some households use it for washing, for domestic uses in the kitchen, and even for drinking. The objective of this work is to assess the risks to which users are exposed when consuming collected and stored rainwater. The hydrogen potential analysis revealed an average content of 7.05. The turbidity value is less than 5NTU.The conductivity has an average value of 0,01005 µs/cm. The quantity of chloride ion is very varied for each sample analyzed, with an average of 227.47 mg/l in Cl-. The samples show considerable number of total coliforms.

Severe acute malnutrition is a real public health problem in the Vaku health zone, we note the persistence of cases and the increase in infant and child mortality. This study aims to determine the prevalence and determinants of severe acute malnutrition. This is a cross-sectional analytical study of 479 children under 5 years of age with acute malnutrition, received in the structures of this health zone in 2020. Selected according to the Z-score weight/height or mid-upper arm circumference. The prevalence of severe acute malnutrition was 3.8%, the Khele health area (6.6%) was in first position. Male sex was more concerned and age between 12 and 24 months had the highest prevalence (4.7%). We performed multivariate analysis with logistic regression of associated factors. Non-exclusive breastfeeding, inadequate complementary feeding, monthly income ≤ US$ 30 of heads of household and non-attendance at SPC have been identified as potential determinants of severe acute malnutrition in this health zone. Incomplete immunization status, household size of more than six people and access to difficult food were identified as protective factors for severe acute malnutrition. The other factors studied did not present the link with malnutrition in this health zone. Several cited studies found similar results. We suggest the effective integration of infant and young child feeding activities into the structures of this health zone that could reduce this prevalence.

The dynamic capability notion has been studied from a theoretical point of view. The authors note the lack of work on the dynamic capabilities’ deployment. Our research is based on Teece’s (2007) conceptualization that a competitive company mobilizes three dynamic capabilities: sensing, seizing and transforming. The study is based on a case study of 15 Moroccan SMEs considered to be competitive. It is based on a qualitative study: surveys were carried out to collect data from the owner-managers of these SMEs. Our results validate that the SMEs studied are mobilizing dynamic capabilities, and highlight areas for improvement for future development.

The objective of this paper was to develop a computer application that would allow the various agents of the cadastral division in the city of Lubumbashi and the Director of Land Affairs to register information about the various people who come to apply for land, to facilitate the consultation of information, etc. The application would facilitate the registration of information about the various people who come to apply for land, to facilitate the consultation of information, etc. This application would facilitate the registration of information relating to the various people who come to apply for land, facilitate the consultation of information, etc. This solution is of crucial importance, as it will allow us to avoid the problem of land conflicts which has become commonplace in the city of Lubumbashi. It will also allow the registrar of real estate titles to verify the different plots of land that are available without having to move and in real time.

This work is part of an article developed within the Higher Pedagogical Institute of Lubumbashi (DRC), It leads to the design of the website that will serve as a tool for students of the said institution. Maintenance activities, in the sense of troubleshooting equipment, have always existed. But these activities were initially little or not formalized: they were not necessarily carried out by specialized staff, nor were they supervised by specific methods. In addition, they consisted essentially of repairing equipment; once it was repaired, the repairer was content with the solution to the problem and forgot to archive it somewhere and even if he did, the solution always remained confidential, that is to say, not shared. This collaborative approach makes it possible to transform the Internet into a global forum where the most distant Internet users can meet and form communities according to their tastes and aspirations; and it also allows access to information of common interest, the sharing of opinions... Thus, we admit that the implementation of this tool will certainly help to improve the computer education system and encourage students to have the habit of documenting themselves and the failures encountered for the reusability of the solution and to push students to research, read, share information and stamping. It also aims to help students remedy the various troubleshooting problems they will encounter in their daily lives and put them at the height of a precise diagnosis.

This study aims to investigate the diversity of species and assessing the availability of woodfuel plants used in rural areas by Koulango and Lobi populations on Eastern periphery of Comoé National Park. Two surveys were conducted in ten villages: a house-to-house interview and an individual walk-in-the woods interview with some informants. Frequency of citation use value were used to estimate the local knowledge of woodfuel plants. Floristic inventory based on random plot sampling method was applied on 200 small squares. A qualitative analysis through the households has showed that firewood was the fuel most used in households. Among the useful species, 6 plants were the most use species by both local populations. According to plants availability, in Comoé National Park, juvenile individual of 12 plants such as Berlinia grandiflora, Burkea africana and Vitellaria paradoxa were the most abundant species. Adult individual of plants were the most abundant species. In rural area, 8 plants like Daniellia oliveri, and Vitellaria paradoxa were the most abundant species. Annona senegalensis, Saba senegalensis and Vitellaria paradoxa were the 3 most abundant species. However, juvenile individual and adult individual of 16 plants such as Bombax costatum Margaritaria discoidea and Raphia sudanica were very rare in both areas (CNP and rural area). The study pointed out the importance of use value as tool to select the species which conservation must be emphasized in the management plans to meet not only the need of the populations but also to improve the conservation statute of the species. Finally, this study raises the fact that there is an urgent need to develop methods for a sustainable use of these plants from Eastern periphery of Comoé National Park.

This study is part of the World Research Program for sustainable cities (ecological cities). Program coordinated by Massasuchetts Institute of Technology (MIT) and Word Resources Institute (Washington, DC). Indeed, according to the International Development Research Center (2007), more than 60% of humanity will live in urban areas at the dawn of 2025. This concentration in urban areas is not without impact on the urban environment. It amplifies and aggravates the content and depth of the urban ecological crisis. Victims of this situation are, above all, the cities of developing countries, particularly characterized by the lack of urban planning. Thus, faced with strong global urbanization, ekistics, a support for urban ecology, presents appropriate solutions so that we can manage to renovate environmental policies, in order to place third millennium cities in the orbit of sustainability. urban environmental.

Floods are sources of natural disasters around the world. They occur following flooding of rivers and an overflow of urban sanitation drainage routes. This impressive phenomenon causes enormous losses in the ecological, economic and social sectors. According to current statistical data (2010-2020), floods caused more than five million victims worldwide (OCHA, 2022). Obviously this, without taking into account the other effects: material damage, service disruptions, health risks, famine, psychological trauma, etc. Faced with the intensification of these phenomena in Kinshasa, thanks to scientific investigations carried out in the field, this study proposes integrated strategies likely to contribute to the sustainable prevention of flooding in the lower part of the city of Kinshasa. This approach will be accomplished in response to the Sendai Action Plan (2015-2030) which wants scientists to become deeply involved in the quest for sustainable prevention of natural disasters in their societies.

Food security is a major challenge for developing countries. Non-Timber Forest Products (NTFPs) are a source of income for families, improving their living conditions. Tamarind is a NTFP used for many purposes, both for food and industrial purposes. However, it suffers from pest attacks. This study aimed to evaluate the post-harvest practices of tamarind fruits and the constraints related to its storage in the communes of Bobo-Dioulasso and Ouagadougou. A survey conducred in the form of a semi-structured interview toward 113 respondents in Bobo-Dioulasso and 138 in Ouagadougou. The participatory diagnosis showed that the majority of respondents in Bobo-Dioulasso (70.19%) and Ouagadougou (57.33%) considered insects to be the main cause of damage to the pods. We observe a preponderance of perforated beans (63.16%) in Ouagadougou, while in Bobo-Dioulasso the percentage was 29.85. After collecting the pods, 78.95% of the farmers in Ouagadougou dehull the pods immediately and then keep the pulp without further drying, in contrast to Bobo-Dioulasso (16.67%) where only a minority practice this. More than half of the interviewers sell tamarind to meet specific needs. As for control methods, the main ones are steaming of tamarind used by 72.92% of farmers in Ouagadougou, while in Bobo-Dioulasso only 25.64%. These results show that tamarind pods are highly exposed to insect attacks. It is therefore necessary to investigate the improvement of traditional control methods by including other natural alternatives in order to minimize losses and promote tamarind exploitation.

The liquid-insulated power transformer is the most critical and expensive component of the power supply system. In order to improve monitoring of the state of health of these devices (transformers) installed on the power grid in the bank of the large metropolis of Abidjan, dissolved gas analysis (DGA) was used. Conventional interpretation techniques were developed to diagnose transformer oil. The database we used consists of those of the Compagnie Ivoirienne d'Electricité (CIE) in 2018. It includes 25 samples containing analysis of the five main dissolved gases (H2, CH4, C2H2, C2H4, C2H6). The five defect classes we considered, namely partial discharge (PD), D1 and D2 electrical defects, T1&T2 and T3 thermal defects, are taken from the IEC and IEEE. For interpretation, five methods were adopted, namely the IEC, Doenenburg, Rogers criteria using the ppm gas concentration ratio technique, the Duval triangle using percentage gas concentrations and the IEEE criterion using ppm gas concentrations. The highest success rate of 72% was obtained when using the Duval triangle criterion. But the greatest consistency with a rate of over 70% was observed using the IEC ratio criterion.

The aim of this study was the determination of phenotypic and zootechnical characterisation in ovine breed slaughtered at the Port-Bouët slaughterhouse for butchery in the city of Abidjan. Thus, a study was carried out on 120 slaughtered ovines breeds, including Djallonké and Sahelian ovine. Indeed, before slaughter, individual and direct observations of breeds, sex, ages and coat color characteristics were done. Also, measurements of the height at the withers and the thoracic perimeter. were done. Then a descriptive analysis was performed, followed by a Chi-square test for qualitative variables. In addition, an ANOVA was performed for the quantitative variables. The results show that ovines of the Sahelian breed (82.5%) are the most slaughtered. Thus, the most dominant coat colors in Djallonké and Sahelian ovine breed were respectively black-piebald (33. 34%) and white (47.48%). Also, ovine 3 years or older (57.50%) were the most slaughtered. In addition, Djallonké and Sahelian ovine breed without horns and pendants were more slaughtered. The breed had an influence on the height at the withers (p < 2e-16) or the thoracic perimeter (p = 1.67e-11). Similarly, sex and age had a significant effect on thoracic perimeter. However, the sex factor had no effect on the height at the withers. In conclusion, the breeds, sex, ages or coat colors of slaughtered ovines at the Port-Bouët slaughterhouse are various.

This research questioned the capacity of Solidarity Mutual to offer microfinance products adapted to the specificities of beneficiaries, and to contribute to improving the living conditions of beneficiaries, by putting into practice their social mission, which is especially an agro-pastoral area. To achieve this goal, a quantitative approach was used, with a questionnaire to quantify the results. Our universe of analysis or sampling frame consists of the beneficiaries of the microfinance services of de Solidarity Mutual. The size of our study population is 213 Solidarity Mutual for 3013 members. We used probabilistic sampling, using a frame made up of finite lists of the population, our sample is random simple, and its size is 700 members surveyed MUSO sites Bunia, Irumu, Aru and Djugu. After analyzing the data collected, it emerges from the results obtained that the MUSOs do indeed offer microfinance products adapted to the socio-professional specificities of the poor populations in the three of the five territories of Ituri, and effectively put into practice their mission to contribute to improvement of social living conditions of members in 77% of cases.

This article deals with the design and implementation of a new web application for the evaluation of lessons and teachers by students. This application is accessible from a smartphone or any other computer device to allow the student to evaluate. The latter has access to the application once registered, hence his number and first name gives him access. Finally, the application produces a summary evaluation report for a teacher per course and annually for all the courses given by a teacher according to the criteria defined in the Vadmecum for managers of a higher education and university establishment. It is designed in client-server architecture with PHP programming language which is mainly used to produce dynamic web pages through a HTTP-server, but can also function as any interpreted language locally with a database that runs on the MySql server allowing the exploitation and manipulation of stored data. The man-machine interface offers the user a user-friendly form containing clear and explicit criteria and validation button and also a button allowing the student to check all his courses already evaluated.

The drinking water needs of the populations of the localities of Bébouo-sibouo, Zaliouhan and Krébleguhé are increasingly accentuated and constitute one of the major problems in this area of west-central Côte d’Ivoire. The aim of this work is to strengthen the drinking water supply system in order to meet the needs of the population. To solve this problem, the methodology was based on simulating the operation of existing and complementary networks using Epanet software. The results show that the population’s needs in 2019 are estimated at 400,032 m3/d and 685,406 m3/d in 2031. The pipes selected after sizing are all in PVC with nominal diameters of 10 bar, and comprise a PVC DN 200 mm for delivery, a PVC DN 90 mm for supply pipes (main pipe) and another PVC DN 53 mm for distribution. Simulation of the network shows that there is a malfunction in the existing system, which can be explained by the low or even zero pressures recorded only after 1 h of distribution throughout the existing network. Even if pressure results are good on the complementary network, low flow velocities are recorded on the whole network. As a result, further boreholes need to be drilled to boost production. This model will therefore be retained and used to support the implementation of this water supply project.

Introduction: The profession of motorbike taxi driver is flourishing in Africa. The aim of this study was to investigate the determinants of traffic accidents involving motorbike taxis. Methods: This was a cross-sectional, descriptive study conducted from 3 January 2020 to 2 February 2020. The study population consisted of motorbike taxi drivers admitted to the emergency department of the Thies regional hospital (Senegal) after a traffic accident. Results: A total of 63 motorbike taxi drivers took part in the study. The average age was 26.7 years. The level of education was low. The average daily takings were 6,627 FCA francs. The drivers were not wearing helmets in 81% of cases. Similarly, 95% had no driving licence. Stress (39.7%), risky sexual behaviour (36.5%), drug use (22.2%) and alcohol consumption (6.3%) were also found. The main causes of accidents were speeding (96.8%), the effect of other road users (96.8%), the driver’s profile (50.8%), the condition of motorbikes (50.8%) and road conditions (14.3%). The regulations in force on motorbike taxis were perceived bad in 57.1% of cases. Reducing police harassment (95.2%), reducing the cost of taxes (90.5%), training in the highway code (69.8%) were the main expectations of drivers. Conclusion: Motorcycle taxi drivers are highly vulnerable to road accidents. The public authorities need to raise awareness and clean up this type of informal transport.

This research aimed to establish standards for clothing designed for children with motor disabilities, specifically those with cerebral palsy. The research utilized a descriptive and analytical approach, and data was collected through a questionnaire given to caregivers of children with cerebral palsy. The research sample consisted of 10 caregivers, and the results showed that trousers and a shirt were the preferred clothing items for children with cerebral palsy, rather than overalls. The Kingdom's logo was also preferred to enhance national identity. Based on these findings, the research recommended further studies on alternative solutions and the use of smart fabrics to address clothing and health problems faced by people with special needs.

The great debate and the big argumentative elevated by the matter of recognition of the existence or not of the African Philosophy justify a systematical analysis of African thoughts to quarry the philosophical ingredients. In fact, for many African pessimists, it was unthinkable to consider an African ideology. Many prejudices have been advanced for that goal supporting the mental inability of niggers. Here, we can mention that the major marks the « pre-logism» of Levy Brühl confirming that the negroes have a pre-logical mentality. Hegel, denies all the history, every movement and development to Africa testifying that all happened in Africa highlights from Asian and European world. Towards this african reification, it becomes imperative to wonder if Africa has got real ideologies, their matters, and perspectives. This is the task on which harness different authors of this section thus the major intention is to bring up the readers discover the great African ideologies and their contributions in the history of african thought in particular and in the universal thought in general.

In the Italy devastated by occupational wars imposed by strangers, Machiavel felt called upon decides to give a donation to Prince Laurent de Medicis which would allow him to take thecountry in this chaotic situation. The gift was a collection of Machiavel’s experiences presented in the «Prince» in a form of a Prince’s code of laws or conduct. We was interested in this unpretentious scientific research due to duties assigned to «Prince» by Machiavel in the «Prince», a well-known work by intellectuals and which has become paramount book for politicians. This feat works encloses principal duties such as: duties towards people, duty of being feared but not blamed and the duty of speech which does not break down the power. Machiavel sermonize realistic and practical politics which considers humans not as they should be, but as they are: wicked, envious...he does not sermonize cruelty, avariciousness, etc. to avoid social nuisance. However, he wants to show the possibility for the leader to do evil in order to overcome and maintain territorial integrity, but also the social welfare, going against blind and fierce cruelty which ruins the «Prince». Also, Machiavel substitutes politics for moral while it is the moral which serves politics. It is against such a practice of doing things that the writers attempts to give warming to their readers through this scientific research understudy, because nowadays, many leaders practice this hypocritical politic sermonized by Machiavel.

The research on the prevalence of gastrointestinal parasites of antelopes and goats has been conducted in and around the Kahuzi-Biega National Park. The method of collecting dung by hand coupled to that of the laboratory coprology analysis were used. The results of the study show that the antelope and the goat have in common as roundworms trichostrongylus, Nematoduris and flatworms, Fasciola gigantica (Trematodes) and as other worms, Coccidia. Gastrointestinal parasites in both sites (PNKB and around the PNKB).Trichostrongylus, are abundant in antelopes and goats, but Coccidia are abundant around the PNKB so in goats. Goats have a high prevalence of parasites for the same species found in the two sites namely trichostrongylus, (51.2%), Nematoduris (8.7%) and Coccidia (47.5%) against trichostrongylus, (47, 5%), Nematoduris (1.2%) and Coccidia (21.2%) in antelopes whereas for Fasciola gigantica, antelopes have a high parasite prevalence (26.2%) than goats (20%). The other prevalences of parasites in antelopes are distributed as follows 5% respectively for Gardia lamblia and Molineus, 1.2% respectively for Balatidium parcel, Monezia expensa, Cappilaria sp and Ascarus lumbricoides and 2., 5% Trichuris trichura. The parasite infestation rate in the two small ruminants (antelope and goat) is at least 10 parasitic elements counted on the slide of Molineus, Trichuris trichura, Ascarus lumbricoides, Cappilaria sp, Monezia expensa and Nematoduris while for Coccidia and tricostrongylus, is 10 to 100 parasitic elements counted on the blade. The infestation rate of gastrointestinal parasites is 10.1% in antelopes and 31.9% in goats. Goats around the PNKB are quite infested with trichostrongylus, as the antelopes at PNKB. For Coccidian parasites, goats around PNKB are infested in the same way as PNKB antelopes.

Zoonosis are not a recent problem in the history of humanity. Throughout history, humans have lived with animals and may have contracted diseases, either through direct contact with animals or through contaminated food or the environment. Zoonotic agents often cause fatal diseases, such as plague, rabies, anthrax, brucellosis and various bacterial infections. Regarding the healthiness of meat delivered for consumption in Bukavu, out of a total of 49 samples collected and analyzed, the average FMAT (Total Aerobic Mesophilic Flora or general contamination) is 155.5. 106, total coliforms are 101.106, faecal coliforms 132.106 and pathogens 133.106/g of meat sample. The meats are more contaminated by a bacterial microflora with high loads. They are therefore unfit for consumption because they can cause toxi-infections, zoonosis and other infectious diseases.

16 dogs (Canis familiaris) of local breed 12 males for castration, 4 females for the diagnosis of an unknown pathology were administered a combination of anesthetic agents which included medium drugs of Xylazine 1.49 mg / kg) for premedication. After 10 minutes the animal was injected with an average dose of ketamine 14.72 (mg / kg). The infusion route and the parameters were recorded every 10 minutes time intervals (heart rate, respiratory rates, oxygen saturation, temperature, color of the mucous membrane, reflexes, capillary replenishment, blood sugar level and carbon dioxide). At 29.9 minutes, the injection of Diazepam came through the vein to sedate the animal. The average heart rate of the individuals was 86.89 beats per minute that of all intervals was 88.06 beats per minute. Respiratory rate was 16.73 breaths per minute and the average of all intervals was 21.89 breaths per minute. The average temperature for all individuals was 37.13 0C and for all intervals were 36.90C. The average oxygen saturation for individuals was 91.57% that for all intervals was 91.96%. The carbon dioxide for individuals was 32.52 mmHg and for all intervals was 31.4 mmHg. Anesthesia in dogs for suppression of the pain, good muscle relaxation and anesthetic depth that can ensure the well-being of animals and the surgical procedure.

Scar pregnancy is an ectopic, life-threatening pregnancy (hemorrhage or uterine rupture) that can also involve functional prognosis (hysterectomy). Its incidence is rare, but is likely to increase due to the rise in Caesarean section rates, these past few years. The clinical signs include metrorrhagia in variable abundance and/or pelvic pain in patients with uterine scarring. Diagnosis is made by endovaginal ultrasound, using the Vial criteria. The case we report in this article will enable us to discuss the pathophysiological, diagnostic and therapeutic criteria of this pathology, with the help of a literature review.

Water, a natural resource whose usefulness no longer needs to be demonstrated, is currently at the center of debate. Drinking water is a key determinant of household well-being. This is the reason why the value of water and its contribution to human well-being enjoy particular recognition. The objective of this article is to analyze the determinants of access to drinking water in rural areas in Burkina Faso. The research methodology used is quantitative. Data was collected through a questionnaire sent to 284 households in the rural commune of Saaba. From the analysis of this data, it appears that most households store their drinking water for a long period, the distances traveled to have access to a source of drinking water is long, the bad habits which consist of obtaining water in non-potable sources remain relevant. The estimation of the Heckman selection model yielded the following results. Indeed, the sex and age of the head of household, the income of the household, its size, the level of education of the head of household, the taste of the water, the location of the water source, the reliability of the source, the number of children in the household, are the main determinants of adequate access to drinking water in rural areas in Burkina Faso.

The waste is used to fertilise fields. Their pre-treatment can impact on human health and the environment. A study was carried in Bobo-Dioulasso, precisely in Kuinima and Dogona, with the main objective of assessing the impact of waste treatment methods on the environment and health. The data was obtained from individual interviews with farm managers. The results show that 56.67% of the producers practise sorting followed by incineration and 20% practised sorting only, 23.33% of the producers did not perform any treatment. Sorting caused injuries to 33.33% of the producers, 10% were harassed by insects. As for the impact of the treatment methods on the environment, 83.33% of the producers who sorted their waste had their fields invaded by new weed species, compared to 76.47% of those who sorted and incinerated. For 88.23% and 66.67% of the producers who were sorting followed by incineration and sorting only respectively, the crop yield was good. From these results, we can conclude that the waste treatment methods used by producers have negative effects on the environment and human health.

In the perspective of improving cattle breeding and their health and for a better understanding of tick resistance to acaricides, this study was conducted in the Department of Korhogo. The objective was to verify the knowledge and skills of farmers on the use of acaricides and to contribute to the reduction of the impact of ticks on livestock productivity. Thus, a cross-sectional survey was conducted using elaborate questionnaires, followed by specific interviews with livestock stakeholders in the study area. The results showed that the majority of cattle breeders (58.06%) are Ivorians. Among them, 58.07% are between 27 and 45 years old. In addition, 51.61% of cattle farms have at least 50 heads with 83.87% being zebu breeds. In addition, to control ticks, 54.84% of farmers use alphacypermethrin as an acaricide, 41.93% of which are zebu breeds. However, none of the farmers used this medicine in accordance with the instructions and standards of use, 68% of them used an underdosed treatment and 32% an overdosed treatment. The most common method of treating cattle against ticks was spraying. The presence of ticks despite the use of alphacypermethrin could be related to the misuse of this product, resulting in resistance issues. It would therefore be important to respect the normal dosage of the product. In order to minimise resistance problems, awareness is needed among farmers for the proper use of acaricide products as well as all other drugs.

In the present work, the cement and/or matrix, pores, and grains present in sandstones were quantified by tele-petrography. The selected sandstones come from the superficial formations of Ivorian onshore basin and the deep formations of offshore basin. A total of six sandstones, three from each part of Ivorian basin, were analyzed. The tele-petrographic analysis consisted of processing the images of these sandstones taken under the natural light from petrographic microscope to the R software using the «terra» package. The results show that the quantification of sandstone components depends on the magnification of the microscope image, the grain size, and the sorting. At low and medium magnifications, a small number of images per rock is sufficient to evaluate the proportions of the components. At high magnifications, however, a large number of images are required as they tend to overestimate the proportions of grains at the expense of other components (porosity, cement, matrix) if the grains have a poorly sorted. The presence of phenocrysts accentuates these variations. However, if the sandstones have a well sorting, the proportions of components hardly vary from one image to another, whatever the magnification. The density curves and histograms reveal that the number of components on these curves depends on the proportions; the higher the proportion of a component the better it is represented. Low proportions remain invisible on the density curves. Remote sensing is therefore promising for the evaluation of the petrophysical properties of reservoir rocks.

The droughts of the 1970s and 1980s led the government of Burkina Faso to secure water resources and agricultural production by building large reservoirs and irrigation schemes. In the early 2000s, this policy of securing water resources was pursued through small-scale village irrigation, which involved developing irrigated agricultural areas around small to medium-sized reservoirs. This study presents the case of water management in a hydro-agricultural area located in Mogtedo (Burkina Faso), with a view to proposing optimisation solutions. The study was based mainly on a literature review and the use of the database of the Irrigation Development Support Programme (2011-2016) in Burkina Faso, with a view to assessing the extent to which agricultural water needs are being met. Analysis of water management in the study area revealed organisational and structural shortcomings within the organisations in charge of water management. It also shows that there is a precarious balance between water supply and demand. This balance is threatened by an unfavourable climatic outlook, which could result in a considerable deficit in the reservoir’s capacity to meet the needs of multiple uses. In order to delay the occurrence of such a collapse, solutions have been proposed, in particular, to improve in particular the efficiency of the use of agricultural water and to better protect the water reservoir against sedimentation.

The choice of this subject is related to the object that has activated our attention as a researcher and strikes our imagination. It all started with an exchange between colleagues and an observation made when we were watching a tourist documentary of the city of Lubumbashi, so we were driven by the taste of wanting to improve the tourism process to grant quick access to all sites available in the city for sightseeing. This work will provide the IT solution to the Ministry of Tourism and more specifically to the Tourism Service through the application that will be designed and implemented with regard to the process of tracking tourists and better managing them to maximize revenue.

The SERNIE is an educational system that guarantees the quality of education, the circulation of fake school coins, in short, it fights against anti-values in the school environment. The SERNIE awakens the conscience of parents in the supervision of their children to increase discipline and observation. The Ministry of Primary, Secondary and Vocational Education is working through SERNIE to fight relentlessly all the flaws observed in the head of managers, students and parents alike. The SERNIE is also a powerful weapon of deterrence in the hands of the authorities of the Ministry of EPESP. The choice of our subject is not a random fact, it is explained by the fact that we have seen the way in which the management of student identification works. Certainly, the SERNIE has set very relevant objectives, among which we just mention the identification of students in order to prevent fraud and school vagrancy. But the information system as designed now does not really allow it to achieve its ends.

This study examines the relationship between financial sector development and economic growth in DR Congo (DRC). Indeed, well-functioning financial markets are a key factor in achieving high economic growth, while inefficient financial markets are one of the reasons many countries around the world romain desperately poor. Hence, the development of the financial sector can drive economic growth. The main objective of this work is therefore to determine the influence of the financial system on economic growth in the DRC). By conducting this study, we specifically want to verify whether financial development indicators are significantly related to the growth of the Gross Domestic Product (GDP) in the DRC. The econometric analysis is based on a general linear model, and the data used for this analysis come mainly from the World Bank and the Central Bank of Congo. The results obtained show that the savings rate has a positive and significant impact on economic growth in the DRC; the interest rate also influences economic growth but in a negative way. These results show that the development of the financial sector promotes growth in the DRC.

In this work it was a question of evaluating the productivity of different varieties of local cassava grown in the Territory of Kabongo. To achieve the objectives we have set ourselves, the data were collected at MUKOLA following a completely randomized experimental design during the month of March of the year 2021. The yield parameter in terms of the number of chips per variety was evaluated. It emerges from the analysis of the variance of the following classification: KILEBE = KATSHILUSA ≥ ASUMINI = MULOKO with regard to the number of chips per variety.

In this article we will try to study the motion of a charged particle electro dynamic. Note that a moving charged particle finds its application in electronics, more precisely in television and the vacuum tube, thus giving rise to the different types of screen currently used to display an image of a transmitted object. Note that a moving charged particle is subject to two fields: the electric field □( (E ⃑ )) and the magnetic fiel□( (H ⃑ )) . This article will be the subject of a study in uniform electric field taking into account the physics laboratory reference of the department of physics and applied sciences of the National Pedagogical University. For this purpose, we used for our experiment: - Two metal plaques ; - An electron gun having a cathode et anode ; - A low and high voltage generator ; - A screen (flat surface for projecting light). The objective of this study is to establish the different equations of motion of a charged particle an uniform electric field E in a projection frame (O:i,j,k). To close the study, we will finally consider the electrical bending of a charged particle moving between two plaques having different potentials.

In Côte d’Ivoire, the base layers on road are generally made from lateritic soils which must respect specification in order to guarantee its quality. Unfortunately, most of the road bases made with lateritic soils from the sedimentary basin degrade early. This investigation aims to determine the geotechnical characteristics of the natural lateritic soils from sedimentary basin used for road construction to understand the reasons for their early degradation. Thus, soils from Songon and Samo were subjected to tests, to know their intrinsic properties. Particle size distribution, Atterberg limits and methylene blue test, modified Proctor, California Bearing Ratio (CBR), and chemical and mineralogical tests were performed. The soils of Samo and Songon contain appreciable quantities of iron and aluminum oxides and silica, but small quantities of titane, manganese and magnesium oxides. They are mainly composed of kaolinite and quartz. Furthermore, they are massive consisted of sand packed in fine matrix (49 % and 46 %) for soil of Samo and (62 % and 33 %) for soil of Songon but no gravel. The dry densities, the optimum moisture content and CBR at 95 % of maximum dry density obtained for the soil of Samo and Songon are respectively 1.83; 15.2 %, 24 % and 1.88; 16.7 %, 20 %. These soils are not suitable for use as base layers on road because they are still in a primary stage of lateritic soils formation.

To simulate the propagation of floods in the Senegal River valley in order to lay out the flood risk maps, we used hydraulic methods calculating the flooded surface from the topography of the minor and major beds. To this end, the HECRAS model and GIS (ARCGIS and HEC-GeoRAS) were used on the Bakel-Matam reach. The work was done in steady state and allowed us to map the risk of flooding on this Bakel-Matam section in the Senegal River valley for different floods. to do this work, water levels and flows were used for the calibration and validation of the HEC-RAS model. The Nash criterion was used to optimize the HEC-RAS parameters. The flood extent obtained by this model was exported and visualized in ArcGIS. Thus, the flood mapping results obtained made it possible to detect a certain number of villages at risk of flooding for the hundred-year flow, wich shows that the Senegal River Valley is vulnerable to floods. Moreover, this was demonstrated by the average catastrophic flood which caused flooding that could impact approximately 24,071 people. The characteristics (height, speed and propagation time) for each flood were analyzed. The promising results obtained showed that the couple HECRAS and GIS is an effective tool for mapping floods and could be used as a tool to help planners in planning.

In this article, it is a question of studying the behavior of a band pass filter in BF and HF with passive elements. Said filter is widely used in electronics and telecommunications with many applications such as: manufacture and assembly of loudspeakers, limitations of working frequencies in a given interval according to its band, etc. We preferred to do this study based on mathematical and physical models which allowed us to discuss and interpret the different results obtained after simulation at the physics laboratory of the National Pedagogical University (UPN/RDCongo-Kinshasa) and which are presented as follows: In Low Frequency (BF): The capacitor blocked the signal and behaved like an open switch, on the other hand the coil allowed the signal to pass through. It acted as a closed switch. Therefore, the voltage at the filter output was zero; In High Frequency (HF): We had the opposite behavior in BF and the voltage at the output of the filter was always zero. The studied behavior led us to the determination of the band pass filter. The tool used for the simulation in Matlab, very powerful engineering software.

Electric energy is an essential factor in the economic development of a country. It is generally produced in power plants located at points more or less distant from consumption centers. To reach consumers, this energy must go through several stages including transport, allocation and distribution. Formerly carried out almost exclusively with alternating current, the transport of electricity over long distances has increasingly been done with direct current over the last few decades. Each mode of transporting electrical energy has certain advantages over others which militate in its favor when it comes to transporting electrical energy over long distances. This article aims to analyze HVAC and HVDC systems from a technical, economic and environmental point of view in order to identify for each system its strengths as well as its weaknesses, and also to define the criteria on which we are based. basis for choosing one or another mode of energy transport, depending on the constraints imposed.
