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. ...

Delineation of the immune correlates of protection in natural infection or after vaccination is a mandatory step for vaccine development. Although the most recent techniques allow a sensitive and specific detection of the ...

In part I of this series the pure component PHCT-DNSK equation of state (EOS) was presented. In this paper the EOS is extended to describe mixtures, particularly asymmetric mixtures containing one or more low molecular ...

Acute skeletal muscle damage results in fiber disruption, oxidative stress and inflammation. We investigated cell-specific contributions to the regeneration process after contusion-induced damage (rat gastrocnemius muscle) ...

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 ...

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 this paper we discuss the various effects on resistivity of thin metal films, concluding that grain boundary scattering and the material's electron-mean-free-path are the dominant factors. We also present an effective ...

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 ...

Maternal and child mortality rates are still unacceptably high in South Africa. The health status of women in peri-urban areas has been influenced by political and socio-economic factors. Examining socio-economic variables ...

The leaves, flower and stems of the southern African angiosperm resurrection plant Myrothamnus flabellifolia were investigated at the ultrastructural level to determine the source of previously reported fungal contamination. ...

Analytical chemistry is playing an ever-increasingly important role in the global wine industry. Chemical analysis of wine is essential in ensuring product safety and conformity to regulatory laws governing the international ...

The role of protective immunity to Plasmodium falciparum (Pf) malaria in Burkitt lymphoma (BL) is unknown. We investigated the association between BL and antibodies reactive to SE36 antigen, a recombinant protein based on ...

A land transaction is generally not a recurring action for most buyers and sellers their experience and knowledge are limited for this reason the services of property agents and valuers are sometimes used just to get ...
