    Abstract: In this paper, the problem of ill-posedness of solution in identifying multiple groundwater flow parameters from hydraulic head data and other ancillary data was assessed. The solution approach to the parameter identification problem is sought by applying the Least Squares, the Adjoint, the Conjugate Gradient Method and a proposed Parameter Transfo... Show More

    Abstract: Vitamin C, also known as ascorbic acid, in five different fruit samples of orange, mango, watermelon, pawpaw and pineapple were determined with the view of developing suitable mathematical models for subsequent estimation of the vitamin in the fruits after several days of storage at temperatures of 4 and 29 (±1°C) respectively prior to consumption....

    Abstract: The pathogen of Buruli Ulcer (BU) is known to be Mycobacterium Ulcerans whose mode of transmission is entirely not known, although the disease is recognised to be associated with contaminated water. The hypothesised transmission involves humans being bitten by the water bugs (vector) that prey on mollusks, snails and young fishes. The hypothesised t... Show More
