Abstract: Background: The study of the fish population in sector IV of the Ebrié lagoon is intended to constitute an approach for determining indicators of fisheries in the lagoon environment, from a resource management perspective and to facilitate the interpretation of biological phenomena. Materials and Methods: Sampling was carried out from February 2014 to January 2015 using monofilament nets at four stations (Layo, N'djem, Songon and Taboth) in sector IV of the Ebrié Lagoon. Results: The results showed that.......

Abstract: The physico-chemical properties of grilled bacon (GB) as influenced by some chemical preservatives such as Butyl Hydroxyl Toluene (BHT), citric acid and sugar were investigated. Four samples comprising GB + 0 ppm BHT + 0.5% citric acid + 2% sugar (GBC1), GB + 0.1 ppm BHT + 0.5% citric acid + 2% sugar (GBC2), GB + 0.2 ppm BHT + 0.5% citric acid + 2% sugar GBC3) and the control (GB + 0 ppm BHT + 0% citric acid + 0% sugar; GBC0) were produced.....

Abstract: This study aims to test the capacity of raw clays, clays chemically activated with hydrochloric acid (𝐻𝐶𝑙) and thermally activated clays from three quarries in Tanout township of Zinder region (Niger) in the elimination nitrate ions (𝑁𝑂3−). The methodology is based on tests with synthetic waters containing 𝑁𝑂3− ions by varying certain parameters (contact time, pH, mass, concentration and temperature), and an application on natural waters containing high 𝑁𝑂3− contents of certain drillings in the same region while maintaining the optimized parameters. The......

Abstract: Justification: The main river in the district of Caraparu, in the municipality of Santa Izabel do Pará, is the Caraparu River, which originates in the city of Santa Izabel and flows into the Guamá River, which is of great importance for agriculture, tourism and, in some cases, consumption. Therefore, there is a need for monitoring to ensure water quality. Objective: analysis of the physiochemical parameters of the waters of the Caraparu River along the course of the Caraparu district in Santa Izabel.....
