The juridification of sport : a comparative analysis of children's rugby and cricket in England and South Africa
This article takes as its point of departure the notion of juridification in sport and, in particular, the perspective that the term has previously often been used in sport and law literature in a too narrow and limiting ...
Self-sensing for electromagnetic actuators. Part 2. Position estimation
The second paper in a two part series presents the position estimation scheme for an 8-pole heteropolar active magnetic bearing (AMB). The integrated self-sensing assembly comprises a nonlinear MIMO parameter estimator ...
Pressure-drop predictions in a fixed-bed coal gasifier
(Elsevier science, 2011)
In the Sasol Synfuels plant in Secunda, Sasol-Lurgi fixed-bed dry-bottom gasifiers are used for the conversion of low-grade bituminous coals to synthesis gas (syngas). The gasifiers are fed with lump coal having a particle ...
Investigating leakage and bypass flows in an HTR using a CFD methodology
An area that has been identified as significantly important in the development of a high temperature reactor (HTR) is the prediction of leakage and bypass flows. It is therefore essential to understand the influence of ...
N-acetyl cysteine reverses bio-behavioural changes induced by prenatal inflammation, adolescent methamphetamine exposure and combined challenges
Rationale Schizophrenia is associated with prenatal inflammation and/or postnatal stressors such as drug abuse, resulting in immune-redox dysfunction. Antioxidants may offer therapeutic benefits. Objectives The objective ...
