Physico-Chemical and bacteriological characteristics of eleven boreholes located within Owerri city were examined. The bacteriological analyses were carried out using the method of inoculation and incubation of specimens and counted on colonies. Titration method was used to determine chlorides and nitrates while Cu2+, Zn2+ and Mn2+ used atomic absorption spectroscopy (AAS). Iron concentration was...

The study aims at optimizing the uptake of tannins obtained from Piliostigma thonningii by goat skin, using a central composite design. The study was carried out using the central composite design of experiment version 10.0.3.1 which consists of four factors. Bark of Piliostigma thonningii were collected freshly. The barks were dried in an electric oven at a temperature, of 100-105oC and later...

The study of volume changes in binary mixtures is attracting considerable interest from researchers due to the degree of molecular interaction between the mixed solvent molecules and their importance in many chemical industries and engineering disciplines. The experimental values of densities (ρ) and viscosities (η) of pure and binary mixtures of dual-purpose kerosene (DPK) and automotive gas...
