L’échantillonnage des poissons a eu lieu entre janvier et août 2020 à l’aide de plusieurs engins de pêche. Les paramètres physico-chimiques des eaux de surface de cette rivière se situent dans la gamme des valeurs pouvant favoriser la survie des poissons. Au total, 301 spécimens de poissons appartenant à 43 espèces,  regroupées dans 32 genres, 17 familles et 9 ordres ont été identifiées. Les indices de diversité (richesse spécifique et Shannon et Weaver) ont montré que la faune de poissons exploitée dans tronçon le tronçon de la rivière Kwilu est riche, diversifiée et régulièrement repartie. Les poissons Siluriformes (23,5%), Characiformes et Osteoglossiformes (17,6%) ainsi celui des Anabantiformes (11,8%) sont les plus abondants. Au niveau des familles, les poissons Mormyridae (19%), Cichlidae (13%), Alestidae, Claroteidae et Distichodontidae (avec 9% respectivement) sont les plus nombreuses. Les poissons des genres Clarias et Hemichromis (9%), Alestes, Brycinus, Tylochromis, Petrocephalus et Schilbe avec respectivement 5% sont les plus nombreux. En terme d’abondance numérique des espèces de poissons inventoriées, Congothrissa sp (31 individus soit 10,29%), Brycinus imberi et Clarias angolensis (15 spécimens soit 4,98%), Auchenoglanis occidentalis (14 individus soit 4,65%), Clarias gabonensis (13 individus soit 4,31%) et Alestes lateralis (10 individus soit 3,32%) représentent un grand nombre d’individus dans l’échantillon et, Barbus sp (1 individu soit 0,33 %) est faiblement représenté.

Objectifs : Cette étude vise à démontrer s’il y a possibilité ou non d’exploiter cette forme d’énergie renouvelable pour la production d’électricité dans la Ville de Mbandaka. Méthodes : Pour ce faire, nous avons récoltés les différentes valeurs des vitesses du vent par les biais des services météorologiques de la Ville, lesquelles nous ont permis de dimensionner la puissance électrique de l’éolienne à installer et cela en fonction des types d’éoliennes, notamment éolienne domestique et celle industrielle. Les données ont été récoltées dans  la période allant du  1er Janvier 2022 au 31 Décembre 2022. Résultats : cette étude a démontré qu’il y a possibilité d’exploiter l’énergie éolienne dans la Ville de Mbandaka car la puissance électrique à produire va jusqu’aux centaines de kilowatts.

C’est la ville qui a enregistré le 1er cas de COVID-19 à l’échelle du pays et est restée l’épicentre de la maladie. Cette étude vise à montrer l’impact des mesures de prévention sur la dynamique de propagation de la COVID-19 à Abidjan. Elle repose sur la recherche documentaire, les entretiens et une enquête par questionnaire auprès d’un échantillon de 328 chefs de ménages repartis dans les 10 communes de la ville d’Abidjan. Aussi, le test statistique de Khi-2 a été utilisé pour tester la significativité de la liaison entre la maladie et l’exposition aux facteurs de risque. Les Risques Relatif (RR) et Attribuable (RA) ont été calculés pour montrer le lien entre l’apparition des symptômes et le respect des mesures de prévention par la population. Il ressort une dynamique et une inégale répartition des cas de COVID-19 dans la ville d’Abidjan avec une forte concentration dans les communes de Cocody (37 302 cas) et de Treichville-Marcory (14 998 cas) sur la période du 11 mars 2020 au 28 février 2022. Sur l’ensemble des 328 chefs de ménages enquêtés, 70% n’avaient aucune connaissance du mode de transmission de la COVID-19. Concernant les mesures de prévention, seulement 82 soit 25% les respectaient fréquemment tandis que 234 soit 71,3% les respectaient par moment. Les chefs de ménages qui portaient fréquemment le masque avaient 4,59 plus de chance de ne pas présenter les symptômes liés à la COVID et étaient protégés à 58,34%. Tandis que 32,26 % des chefs de ménages présentant les symptômes, étaient liés au respect des mesures par moment mais également à 25,3 % de ceux qui ne les respectaient jamais. Les mauvaises attitudes et pratiques de la population face au respect des mesures de prévention de la COVID-19 demeurent inquiétantes pour une lutte efficace et durable dans la ville d’Abidjan.","PeriodicalId":411069,"journal":{"name":"International Journal of Progressive Sciences and Technologies","volume":"6 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139348190","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
