Scientific and management support for ventilated improved pit latrines (VIP) sludge content.
(2014)Providing adequate sanitation to all in the form of VIP latrines as proposed by the South African Government Strategic Framework for Water Services does not end with building toilets. All municipalities need to plan for ... -
The solid state reduction of chromite.
(1989)High carbon ferrochromium serves as the main chromium source for almost all chromium containing steel alloys. The traditional method for the production of high carbon ferrochromium via the reduction of chromite using ... -
Solubility studies of carbon dioxide in novel hybrid solvents using a new static synthetic apparatus.
(2019)The use of alkanolamine solutions in removing acidic gases from natural gas is common in the industry, but such technologies have disadvantages which include amongst others, solvent loss, corrosion and high heat consumption. ... -
Spatio-temporal dynamics of heterogeneously distributed populations.
(2003)No abstract available. -
A study of an on-line recursive filter applied to a milling circuit.
(1975)No abstract available. -
A Study of boiling parameters under conditions of laminar non-Newtonian flow with particular reference to massecuite boiling.
(1985)Crystallization is done in the sugar industry using natural circulation vacuum evaporative crystallizers known as vacuum pans. the fluid which is known as massecuite consists of a suspension of crystals in concentrate ... -
A study of comminution in a vertical stirred ball mill.
(1993)A 20 litre experimental batch and continuous test rig and 5 litre batch and 50 litre continuous test rigs for stirred ball milling were built at the University of Natal and Mintek respectively. All the mills featured a ... -
A study of hydrodynamics and mass transfer in small bore deep shaft reactors.
(2010-09-08)The phenomenology of vertical two phase flow was examined -
A study of processes occurring in flotation froths.
(1979)While the significant effect that the froth phase has on the performance of a flotation operation has recently been widely recognised, little work has been published which promotes an understanding of the physical processes ... -
A study of the cane sugar diffusion process.
(1972)A mathematical model has been developed to represent the extraction of sugar from sugar cane in the diffusion process. As a consequence of the structure of prepared cane, extraction is postulated to occur via two first ... -
A study of the Fischer-Tropsch synthesis at elevated temperatures in a shock tube.
(1973)The shock tube was used to investigate the product spectrum of the initial stages of the Fischer-Tropsch synthesis carried out at elevated temperatures. Special attention was paid to the relationship between methane ... -
A study of the phenomenon of bridging of sugarcane bagasse
(1996)This work reports the results of a systematic study of the factors that affect the bridging behaviour of bagasse. It shows that traditional bulk solids theory is inappropriate for predicting bagasse flow mainly because ... -
A study of the use of statistical turbulence parameters in correlating axial dispersion data in the central core of air flowing in a pipe.
(1970)The longitudinal fluctuations at a point in the core of air flowing through a 15 cm. diameter pipe at a mean centerline velocity of 13.4 and 29.5 m/sec. were measured with a hot-wire anemometer. This signal, after analog ... -
Synthesis of hydrocarbons and fluorocarbons in a tip-tip arc discharge reactor at high pressure.
(2013)Abstract available in PDF file. -
Thermodynamic studies in CO2 capture through gas hydrate formation technology.
Abstract available in PDF file. -
Treatment and beneficiation of Kraft mill sludge to hydrogen and methane for bioenergy production.
(2021)The key drivers behind research into renewable and sustainable practices are escalating global energy demands and financial instability linked to the depletion of fossil fuel-derived energy resources. Additional drivers ... -
Treatment of dye wastewaters in the anaerobic baffled reactor and characterisation of the associated microbial populations.
(2002)There is potential for the anaerobic baffled reactor (ABR) to be implemented on-site for pre-treatment of coloured wastewaters. The implementation of waste minimisation and cleaner production strategies in industry ... -
A universal segment approach for the prediction of the activity coefficient.
(2016)This study comprised an investigation into solid-liquid equilibrium prediction, measurement and modelling for active pharmaceutical ingredients, and solvents, employed in the pharmaceutical industry. Available experimental ... -
Unlike interactions in simulated methane clathrate hydrates.
(2014)Clathrate hydrates are an ice-like substance consisting of networks of water molecules, held together by hydrogen bonds, enclosing trapped gas molecules. Natural gas clathrate hydrates (in which the trapped gas species ...
