Application of citrus sinensis solid waste as a pseudo- catalyst for free cyanide conversion under alkaline conditions
Santos, Bruno Alexandre Quistorp; Ntwampe, Seteno Karabo Obed; Doughari, James Hamuel; Muchatibaya, Gift (BioResources, 2013-05-08)In this study, Citrus sinensis (C. sinensis) solid waste was used to catalyze the conversion of free cyanide (F-CN) under alkaline conditions; conditions which represent most industrial wastewater containing F-CN. Acid ... -
A Note on the Discrete Spectrum of Gaussian Wells (I): The Ground State Energy in One Dimension
Muchatibaya, Gift; Fassari, S.; Rinaldi, F.; Mushanyu, Josiah (Hindawi Publishing Corporation, 2016-02-07)The ground state energy 𝐸 0(𝜆) of 𝐻 𝜆 = − 𝑑 2 /𝑑𝑥 2 − 𝜆 𝑒 −𝑥2 is computed for small values of 𝜆 by means of an approximation of an integral operator in momentum space. Such an approximation leads to a transcendental ... -
Unsteady contact melting of a rectangular cross section material on a flat plate.
Myer, T G; Mitchell, S L; Muchatibaya, Gift (American Institute of Physics, 2008-10-06)The work in this paper concerns a mathematical model of the contact melting process of a rectangular material in contact with a hot plate. The problem is described by a coupled system of heat equations in the solid and ...
