Morphology and functioning of attachment organs of the Polystomatidae (Monogenea)
(North-West University, 2014)Monogeneans are mainly ectoparasitic on fish, but the family Polystomatidae radiated onto tetrapods and can be found on the skin and gills of the Australian lungfish, in the urinary bladder of frogs, gills and skin of ... -
Morphometric analysis of drainage basins subject to diverse geotectonic controls : the case of the Gamtoos and Crocodile drainage basins, South Africa
(North-West University (South Africa), 2019)Morphometric analysis represents a method to describe basin processes and examine basin characteristics to enable the structure, process and evolution of the landscape to be investigated. This approach has potential to ... -
MtDNA landscape in South African paediatric patients clinically diagnosed with suspected mitochondrial disorders
(North-West University, 2004)The relevance of haplogroups in mitochondrial disease was investigated in this study. Twenty-seven paediatric patients with clinically suspected mitochondrial disorders from diverse ethnic origins were investigated via ... -
Multi-colour photometry of β cephei stars in the large magellanic cloud

A multi-instrument ionospheric Faraday rotation analysis
(North-West University, 2018)Radio interferometers are used for polarimetric imaging. This is one of the types of studies that will be done at the Southern African MeerKAT telescope and in turn, the Square Kilometre Array (SKA) telescope. The polarization ... -
Multi-scale study of massive star forming region NGC 6334I/F
(North-West University (South Africa), 2023)This thesis reports an observational multi-scale study of the high-mass star-forming region NGC6334I=F on scales ranging from 10 000 AU down to 1 AU. In 2015, NGC6334I-MM1B started a period of high accretion analogous ... -
Multi-species assessment of South African coal mine reclamation soils for ecosystem recovery
(North-West University (South Africa)North-West University, 2020)At present, there is no comprehensive soil quality assessment practice for the coal mining industry in South Africa. Studies have shown that belowground soil biota are crucial to soil ecosystem functioning and are sensitive ... -
A multi-wavelength approach to solar energetic particle transport using remote sensing and in-situ observations
(North-West University (South Africa), 2022)Space weather (SWx) studies and the development of SWx prediction models have gained significant momentum in the last few years. Large SWx events have the potential to incapacitate technological infrastructure, both on ... -
A multi-wavelength study of a sample of galaxy clusters
(North-West University, 2012)In this dissertation we aim to perform a multi-wavelength analysis of galaxy clusters. We discuss various methods for clustering in order to determine physical parameters of galaxy clusters required for this type of study. ... -
Multi-wavelength Study of Radio Galaxies in MeerKAT fields
(North-West University (South Africa), 2023-10)Active galaxies are distinct sub-types of galaxies; their centres, known as Active Galactic Nuclei (AGN), are the brightest and most persistently luminous objects in the cosmos and the AGN core is where the vast majority ... -
A multi-wavelength study on the low-mass stellar populations of the southern high-mass star-forming regions RCW 34 and NGC 2626
(North-West University, 2019)The physical processes of how stars form is well understood and documented. However, the finer details of how high-mass stars (M > 8 Mꙩ) form is not yet fully known. High-mass stars are usually associated with class II ... -
Multicolour photometric study of pulsations in a pre-main sequence star V351 ORI (HD38238)

Multicore Architecture Optimization Using Novel Smart Parallel Algorithms for Steganography and Image Feature Extraction
(North-West University (South Africa), 2015)Applications of Steganography and Image Feature Extraction are widely used and adopted by many organizations in the image processing industry. Many of these applications involve computeintensive tasks which demand for full ... -
A multidisciplinary approach for the assessment of rehabilitation at asbestos mines in South Africa
(North-West University, 2010)The asbestos mining industry has left a legacy of pollution that continues to poison former mining areas and surrounding land – posing a significant health risk to local communities. The rehabilitation of sites disturbed ... -
A multidisciplinary assessment of the distribution of African horse sickness in Namibia
(North-West University (South Africa), Potchefstroom Campus, 2015)African horse sickness (AHS) is the most lethal infectious, non-contagious, vector-borne disease of equids and accordingly has been declared notifiable by the OIE – World Animal Health Organisation. African horse sickness ... -
Multifunctional planning : implications for rural development
(North-West University (South Africa), 2021)In the past, urban development and design were known as homogeneous where urban planning leads to spatially separated residential-, working- and commercial areas (Jacobs, 1961:226), resulting in fast-growing peri-urban ... -
Multiple imputation in the presence of a detection limit, with applications : an empirical approach
(2014)Scientists often encounter unobserved or missing measurements that are typically reported as less than a fixed detection limit. This especially occurs in the environmental sciences when detection of low exposures are not ... -
Multiple performance indicators as standard to assess and quantify the ecological condition of a site
(North-West University (South Africa) , Potchefstroom Campus, 2016)Ecological sustainability focuses on the application of ecological principles to justify modifications to the environment to meet the human needs of present and future generations. Sustainability can only be achieved with ... -
Multivariate data analysis using spectroscopic data of fluorocarbon alcohol mixtures
(North-West University, 2012)Pelchem, a commercial subsidiary of Necsa (South African Nuclear Energy Corporation), produces a range of commercial fluorocarbon products while driving research and development initiatives to support the fluorine product ... -
Municipal activities for the environment : a perspective on the Kgalagadi municipal area
(North-West University, 2006)Municipalities as the custodians of the environment in their areas of jurisdiction have the responsibility to care for the environment through their activities. This will ensure that the health and quality of the living ...
