Public financial management reforms for value-for-money in selected South African provincial governments
Far-reaching public financial management (PFM) reforms have been implemented in South Africa in accordance with the Public Financial Management Act, 1999 (Act 1 of 1999) (PFMA). This study assesses the extent to which the PFMA and related reforms have achieved their initial objectives of enhancing …

Applications of Pulse-Magnetised Bulk Superconductors
… has been slow. Pulsed-field magnetisation (PFM) is the most compact and economical method of magnetising bulk (RE)BCO. Unlike field cooling, PFM is typically unable to magnetise a sample to its full capability, though fields significantly higher than those of permanent magnets have still …

Quantifying Solute and Water Fluxes in Headwater Streams Using Passive Flux Meters
… cost and sampling time. A passive flux meter (PFM) simultaneously estimates time-averaged water and solute mass fluxes in flowing water. PFMs have been used in groundwater to quantify contaminant flux but have been used only very recently in streams. In this study, PFMs were deployed in the …
