POSSIBLE SIMPLIFIED RATE MODELS FOR THE STUDY OF THE EMISSION SIGNAL ENHANCEMENT DUE TO EASILY IONIZABLE ELEMENTS DURING FLAME ATOMIC EMISSION (FAES) AND INDUCTIVELY COUPLED PLASMA OPTICAL EMISSION SPECTROMMETRY (ICP-OES)
(2012-08-02)
The effects of excess Na and K on K and Mg atom line emission during air-acetylene flame atomic spectrometry (FAES), and of excess Li and K on Ca, Mg and Sr atom and ion lines in the inductively coupled plasma (ICP), were ...
In Vitro interactionsof plant phenolic compounds and antiparasitic drugs with drug metabolising enzymes and transporters
(2012-07-11)
Drug metabolising enzymes and transporters play a critical role in the pharmacokinetics and hence, absorption, distribution, metabolism, and excretion (ADME) of compounds and medicines. The objective of this thesis was to ...
Characterisation of Cowpea aphid-borne mosaic virus (CABMV) and evaluation of pathogen derived resistance to the virus.
(2012-08-28)
Cowpea is a major source of dietary protein in most African traditional diets, and the crop partially replenishes the soil nitrogen content as a result of its association with nitrogen-fixing Rhizobium spp, and is used as ...
