Excess refractive indices and validation of mixing rules using binary mixture of methyl laurate + Pentan-2-ol at various temperatures (298.15, 303.15, 308.15, 313.15, and 318.15K)

Refractive index is a characteristic parameter of fluids with numerous industrial uses. The values of refractive indices of many pure liquids are known or can be found in the literature. However, when experimental values of the liquid mixtures are not available then refractive indices of binary mixtures and multi-component liquids are frequently assessed from the pure constituents using mixing rules. The refractive...

Dichlorodiphenyltrichloroethane (DDT) and its metabolites in house dust, soil and selected food crops from indoor residual sprayed areas of Apac and Oyam Districts, Uganda

Dichlorodiphenyltrichloroethane (DDT) levels and its metabolites are reported in 75 soil and 75 vegetable samples from the vicinity of homesteads sprayed with DDT during indoor residual spraying (IRS) pilot exercise, carried out in 2008 in Apac and Oyam districts, Uganda as a measure to control malaria. The samples were randomly and conveniently collected in 2020 from selected villages of the districts, extracted using...

Assessment of proximate and physicochemical properties of crude palm oil from south-west and South-south Nigeria

Crude palm oil is most worlds widely used oil, due to its nutritional and economic advantages. The proximate and physicochemical properties of fifty samples from local mills in Southern Nigeria were analyzed to determine their applicability as food and industrial usage applying standard procedures. The obtained results were: Moisture content (1.51 to 2.46%), ash content (0.30 to 0.50%), crude lipids (68.82 to76.77%),...
