Abstract: This research focused on the impact of various preservation techniques on the microbial safety, physicochemical and the antioxidant properties of the indigenous non-alcoholic beverages (soymilk and zobo) sold in Onitsha, Nigeria. Each of the Soymilk and Zobo samples were separated into twenty 330ml samples which were stored under 4-6 degrees Celsius, and the following tested preservation methods: pasteurization (65 degrees Celsius for 25 minutes) and...

Abstract: Denali is a granitic pluton, mostly pink quartz monzonite, lifted by tectonic pressure from the subduction of the Pacific Plate beneath the North American Plate; At the same time, the sedimentary material above and around the mountain was stripped away by erosion. The forces that lifted Denali also caused many deep earthquakes in....

Abstract: Groundwater is the primary source of drinking water in many parts of eastern India, yet arsenic contamination poses a serious threat to human health. This study evaluates non-carcinogenic and carcinogenic health risks associated with arsenic-contaminated groundwater in Murshidabad district using a deterministic dose–response approach. Well-specific arsenic concentration data were used to estimate average daily dose (ADD) under two exposure scenarios: drinking only and combined drinking and cooking. Risk characterization was performed using the Hazard...

Abstract: Persistent illegal mining activities in Nasarawa State continue to pose serious socio-economic, environmental, and governance challenges despite existing legal and institutional frameworks. This study examines the drivers of illegal mining with the objectives of identifying the key factors sustaining the practice and assessing the influence of socio-economic and regulatory conditions on its prevalence. Guided by Political Economy Theory, the study situates illegal mining within broader structural issues such as poverty, unemployment, unequal access to resources, and weak state regulation.......

Abstract: La présente étude s’inscrit sur la problématique liée à l’approvisionnement des fourrages ligneux dans les centres urbains au Mali. Elle a pour objectif de caractériser les acteurs et les espèces ligneuses fourragères commercialisées dans le District de Bamako. Pour ce faire, un tirage aléatoire sans remise a été effectué parmi les six communes du District de Bamako. Il a permis de retenir les communes II, III, V et VI pour effectuer l’enquête. Un questionnaire a été soumis aux acteurs de la commercialisation des fourrages ligneux dans les communes sélectionnées. Au total 65 points de ventes ont été identifiés, regroupant 153 vendeurs repartie en 142 hommes et 11 femmes. La majorité des vendeurs appartiennent à la tranche d’âge de 30 à 39 ans soit 39,87% et suivie de celle de 20 à 29 ans soit 30,72%. Les enquêtes......
