Design and evaluation of a vibration ore flow restore machine
(North-West University (South Africa)., 2021)Ore passes provide a low cost method for gravitational transport of broken ore and waste rock through long vertical distances to lower levels of an underground mine. A hang-up or blockage in an ore pass is undesirable as ... -
The design and evaluation of an l-dopa-lazabemide prodrug for the treatment of Parkinson’s disease
(MDPI, 2017)l-Dopa, the metabolic precursor of dopamine, is the treatment of choice for the symptomatic relief of the advanced stages of Parkinson’s disease. The oral bioavailability of l-dopa, however, is only about 10% to 30%, and ... -
Design and evaluation of chitosan and N-trimethyl chitosan chloride microspheres for intestinal drug delivery
(North-West University, 2005)The absorption enhancing ability of chitosan, a linear polysaccharide, is mediated by protonated amino groups on the C-2 position of the molecules that induce interaction with the anionic sites on the cell membranes to ... -
Design and heat flow analysis of a commercial energy efficient in-line water heating system
(Emerald, 2014)In this paper, the authors provide the design, heat flow analysis and pressure analysis of a commercial energy efficient in-line water heating system in South Africa. The designed commercial in-line water heating system ... -
The design and implementation of a strategic plan in primary schools
(The Clute Institute, 2014)Many policies, strategies and plans have been introduced in South African schools so as to acquire quality education. A strategic plan, as a mechanism of putting schools on a pathway of development and effectiveness over ... -

The design and implementation of information systems for ESCO energy savings software
(North-West University, 2003)Electricity cost of buildings is a major expense for building owners. Improvements in the efficient utilisation of energy is therefore of concern to this economic sector. Unfortunately, existing energy audit tools are ... -
The design and implementation of strategic plans in Primary Schools / A case study of two Mahikeng area office Primary Schools
(2011)A strategic plan is the physical document that embodies the guiding orientations about how to manage the education system within a larger national and local development perspective. Such a plan can lead to school ... -
Design and In vitro analysis of polyethylene glycol based multidrug delivery systems for combination therapy in the treatment of Breast Cancer
(North-West University (South Africa), 2018)Polymer hydrogels are known to be excellent drug delivery biomaterials for unconventional cancer therapy. The polymer hydrogel was prepared via the free-radical polymerization of acrylamide (AAm) in the presence of poly ... -
Design and operation of an ammonia-fueled microchannel reactor for autothermal hydrogen production
(Elsevier, 2018)The present work describes the design and operation of an autothermal microchannel reactor for portable and distributed hydrogen production via ammonia decomposition. The microreactor consists of an array of alternating ... -
The design and operational behaviour of a laboratory scale fixed-bed gasifier
(North-West University (South Africa) , Potchefstroom Campus, 2016)Fixed bed coal gasification and combustion operations form an important part in the global energy supply, and these processes are characterized by complex interactions which are difficult to study on an industrial scale. ... -
The design and optimisation of a bubble pump for an aqua–ammonia diffusion absorption heat pump
(North-West University, 2012)Energy shortages around the world necessitated research into alternative energy sources especially for domestic applications to reduce the load on conventional energy sources. This resulted in research done on the possibility ... -
Design and optimisation of a PCB eddy current displacement sensor
(SAIEE, 2017)Position sensing is one of the crucial parts of many systems, specifically in an active magnetic bearing. The position is used to control the magnetic forces within an active magnetic bearing to keep a rotor levitated. ... -
Design and optimisation of a solar thermal powered Aqua-Ammonia diffusion-absorption heat pump cycle under seasonal variance for residential use
(North-West University (South Africa)., 2021)The diffusion-absorption refrigerator was patented by Von Platen and Munters (1926). The conventionally low coefficient of performance and the high driving temperature have been the focus of most research since its ... -
