Neural network models for leukaemia.
Artificial neural networks (ANN) can detect complex non-linear relationships between independent and dependent variables. Properly trained ANNs have repeatedly demonstrated superior predictive accuracy to other predictive ...
Comparative refining characteristics of northern and southern hemisphere bleached softwood Kraft species.
An experiment was designed to test the hypothesis that each softwood pulp is unique and requires a specific, well defined mechanical treatment to derive its maximum strength potential. Three bleached softwood Kraft pulps ...
Vapour-liquid equilibria studies for binary systems containing 1-hexene and n-hexane
Experimental vapour-liquid equilibria (VLE) data is required for the design of separation
Activity of complex multifunctional organic compounds in common solvents.
The models used in the prediction of activity coefficients are important tools for designing major unit operations (distillation columns, liquid-liquid extractors etc). In the petrochemical and chemical industry, well ...
Binary vapour-liquid equilibria for oxygen-containing compounds.
In this study, there was a need for VLE data for systems of oxygen-containing organic compounds. Experimental VLE data are presented for the following binary systems: a) 2-propanone (1) + 2-butanol (2) at 333.15K, 353.15K ...
Application of water pinch to an integrated pulp and paper Kraft mill with an already highly closed water system.
Sappi's Ngodwana integrated Kraft pulp and paper mill was used as case study for the application and evaluation of the water pinch technique. The technique of water pinch originates from energy pinch, but uses mass flow ...
Analysis of a pilot-scale anaerobic baffled reactor treating domestic wastewater.
This thesis presents a chemical, microbiological and mathematical analysis of an anaerobic baffled reactor (ABR) treating domestic wastewater. The purpose of this study was to gain an understanding of the mechanisms of ...

Infinite dilution activity coefficient measurements of organic solutes in fluorinated ionic liquids by gas-liquid chromatography and the inert gas stripping method
Environmental and safety concerns have prompted an active quest for ―green‖ alternatives to
A vapour-liquid equilibrium study on sub-critical systems using a static apparatus.
High pressure vapour-liquid equilibrium experiments were undertaken with a static high-pressure apparatus designed by Prof. J. D. Raal and commissioned by Prof. D. Ramjugernath. Isothermal VLE binary data data was measured ...
