Author:Andrew, Jerome E; Masetlwa, J; Tesfaye, T; Sithole, Bishop BDate:Dec 2020Bark from trees obtained from sustainably managed plantations used in the production of timber, pulp and paper is an under-utilised waste in many countries across the world. However, in the context of an integrated biorefinery, they may serve ...Read more
Author:Fourie, PJF; Erasmus, TCDate:1977The beneficiation of minus 0,5 mm coal in the Republic of South Africa is reviewed in terms of the availability of fines, the formidability of its cleaning, froth flotation, autogenous cyclones, tables, and dense medium cyclones.Read more
Author:Sebogodi, Keolebogile R; Johakimu, Jonas K; Sithole, Bishop BDate:Oct 2019Acid mine Drainage (AMD) is a low pH, sulphate and heavy metal rich leachate that is produced from oxidation of sulphide bearing minerals commonly found in the host rocks of some mineral ores. The pH augmentation, and sulphate and metal removal ...Read more

Author:Andrew, JE; Johakimu, Jonas K; Lekha, P; Gibril, ME; Sithole, Bishop BDate:2018As part of a broader objective to extract cellulose from sawdust waste material for the production of nano-crystalline cellulose, conventional industrially available processes such as the Kraft and pre-hydrolysis Kraft (PHK) processes were ...Read more
Author:Fagbemi, Olajumoke D; Andrew, Jerome E; Sithole, Bishop BDate:Oct 2021This study reports on the beneficiation of wood sawdust into cellulose nanocrystals (CNC) for application as a binder in the manufacture of particleboard. The cellulose nanocrystal from wood sawdust was extracted using acid hydrolysis and an ...Read more
Author:Moodley, RS; Andrew, Jerome E; Sithole, Bishop BDate:Mar 2018Bark, a major waste residue in the forestry, timber, pulp and paper industry has been shown to be a potential source of valuable chemicals. The chemical composition of bark extracted from South African plantation grown E. grandis and P. patula ...Read more
Author:Rust, C; Smit, Michelle A; Schoeman, DDate:Oct 2020The use of a hybrid photovoltaic (PV) and thermal storage system in houses was discussed by Huang et al. (2019). They found that the dual storage system utilising both batteries and a hot water thermal storage system is effective when partially ...Read more
Author:Maremi, Keneilwe J; Thulare, Tumiso; Herselman, Martha EDate:May 2022The objective of this paper is to provide insight into how the successful implementation of Digital Transformation (DT) can help address the challenges and hindrances in South Africa's e-Government. It is essential to aid South Africa's ...Read more
Author:Page, Philip RDate:Nov 2018The additional benefit of a recent highly optimal technique which keeps the pressure low and constant at a remote location, above the conventional technique, is discussed. The former technique is called remote real-time control (RRTC). The ...Read more
Author:Geldenhuys, CJDate:Jan 1994A hypothesis is developed that environmental factors (rainfall and substrate) determine the potential limits of forest distribution, but that actual forest location pattern is determined by the fire pattern, which in turn is determined by the ...Read more
Author:Belyi, VN; Forbes, A; Kazak, NS; Khilo, NA; Ropot, PIDate:Aug 2009A new type of Bessel-like optical beams, which is distinguished by the dependence on the cone angle from the longitudinal coordinate, is investigated. Such beams have the properties of Bessel beams (ring-spatial spatial spectrum) as well as ...Read more
Author:Litvin, IA; Forbes, ADate:May 2008The authors investigate a conventional resonator configuration, using only spherical curvature optical elements, for the generation of Bessel–Gauss beams. This is achieved through the deployment of a suitable amplitude filter at a Fourier ...Read more
Author:Meyer, Rory GV; Schwegmann, Colin P; Kleynhans, WaldoDate:Jul 2017The detection and classification of SAR imaged vessels at sea is a valuable ability for organisations interested in the marine environment or marine vessels. Matching the SAR detected vessels to their AIS messages allows vessels to be identified ...Read more
