Lack of robust evidence of efficacy confounds understanding of these interventions and their value to the field. It is conceivable that the construct of impaired social reciprocity in PDD presents unique circumstances that require speci...
Fast kinetic methods are used to measure reactions that take place in less time than required to mix the reagents manually and to measure the reaction by usual methods, like UV-visible spectrophotometry and fluorescence. The best known of them are rapid-mixing and relaxation methods, which are used for reactions with half-times in the millisecond and microsecond ranges, respectively. The picose...

a novel silver (ag) nanocomposite electrode was proposed that fabricated from metal nanostructures and ionic liquids. the combined application of unique properties of nanomaterials and ionic liquids in the design of this ag nanocomposite results in electrodes with interesting advantages compared to the conventional metal disk electrode. in the first part of this thesis, the elecrocatalytic eff...
the oxidation of ferrous iron (fe2+) in solution using acidithiobacillus ferrooxidans has industrial applications exclusively in the regeneration of ferric iron (fe3+) as an oxidizing agent for the removal of hydrogen sulfide from waste gases, desulfurization of coal, leaching of non-ferrous metallic sulfides and treatment of acid mine drainage. the aim of this investigation was to increase the...
Introduction Excise taxes are policy tools that have been applied internationally with some success to reduce consumption of products adversely impacting population health including tobacco, alcohol and increasingly junk foods and sugary beverages. As in other low-income and middle-income countries, South Africa faces a growing burden of lifestyle diseases; accordingly we simulate the impact of...
