First we construct an algebra satisfying the polynomial identity [[x,y],[u,v]]=0, but none of the stronger identities [x,y][u,v]=0 and [[x,y],z]=0. Then we exhibit a Cayley-Hamilton trace identity for 2×2 matrices with ...

One of the main pathways for the detoxification of reactive metabolites in the liver involves glutathione conjugation. Metabolic profiling studies have shown paradoxical responses in glutathione-related biochemical pathways. ...

The use of organophosphate pesticides is an integral part of commercial farming activities and these substances have been implicated as a major source of environmental contamination and may impact on a range of non-target ...

Background: HIV-positive pregnant women who drink put their children at risk of both HIV and fetal alcohol spectrum disorders. The province of KwaZulu-Natal (KZN) has the highest prevalence of HIV in South Africa, but has ...

An analytical model for incompressible, generalized Newtonian fluids traversing different types of porous media is proposed. This model is based on the volume averaging of the governing equations. Interstitial quantities ...

In a first stage atmospheric leach in a typical Sherritt Ni-Cu matte leach process, a Ni-Cu-Fe-S Peirce Smith converter matte is contacted with recycled copper spent electrolyte (an aqueous copper sulphate/sulphuric acid ...
