A methodology for the heat of immersion as a measure of wettability of mineral mixtures by Magudu, Anam

“…The measure of the extent to which a mineral interacts with water is called wettability and this is important in flotation processes. This is because the interactions between solid particles and liquid molecules (water) are important in understanding the flotation mechanism and achieving high recoveries. …”

Estimating value at risk and expected shortfall: a kalman filter approach by Van Der Lecq, Maximilian

“…A Kalman filter is used for the first time to estimate both VaR (and ES) to provide an alternative technique to existing industry methods. Modelling the volatility of asset returns as a stochastic process, the Kalman filter uses Bayesian statistics to forecast unobservable data by identifying underlying patterns required to predict future values. …”

Evaluating the Psychometric Properties of Neurodevelopmental Assessment Tools in a South African Context by Zieff, Michal R

“…Neurodevelopmental and behavioural tools, used to assess children's cognitive and psychological development, play important supportive roles in clinical decision-making processes. It is therefore important that inferences made based on the information generated by these tools are valid and reliable. …”

Melanocyte proliferation in wounded skin in vitro: a histological and immunohistochemical analysis by Petersen, Morea

“…This dissertation contributes to the understanding of melanocyte participation and proliferation during re-epithelialisation of skin using an in vitro skin organ culture model of wound healing. To determine whether the culture model used in this study was reliable, skin explants were cultured over a period of 12 days, fixed and processed for histological analysis. …”

Measuring the effects of reaction coordinate and electronic treatments in the QM/MM reaction dynamics of Trypanosoma cruzi trans-sialidase by Rogers, Ian Lloyd

“…Direct investigation of the underlying potential energy functions for B3LYP/6-31G(d), B3LYP/6-31G and SCC-DFTB/MIO point to the minimal basis set as the primary limitation in using self-consistent charge density functional tight binding as the quantum mechanical model for modeling of enzymatic reactions transforming sialic acid substrates.…”

An investigation of improvements to electrochemical precipitation of struvite from source separated urine by Malanda, Nicole Mulenga

“…Usually, magnesium is dosed chemically using salts such as MgCl₂, MgO, MgSO₄ or bittern, together with pH regulating agents but these reactants produce unfavourable chemical by-products and the process tends to be expensive. Previous studies have proven that electrochemical dosing of magnesium is a feasible and reliable method of struvite precipitation. …”
