Assessing the financial viability of renewable independent power production in South Africa
(2014)The cost of energy and national power utility Eskom, is currently under heated debate after the cost of electricity has more than doubled over the past three years, with another five annual increases of 8% approved by the ... -
Co-pyrolysis of torrefied biomass and coal : product evaluation and reaction modelling
(North-West University (South Africa)., 2022)The co-utilization of biomass and coal in existing coal-based conversion technologies has received increasing interest for its ability to reduce the dependence on fossil fuels and produce high quality products. However, ... -
A comparison of selected enhanced (coated) and non-enhanced grass seed types for re-seeding of disturbed areas
(North-West University, 2007)Restoration and rehabilitation activities are presently considered to be a major priority in environmental management, whether the activity implies the restoration of neglected cultivated pastures or degraded rangelands ... -
Composition and diversity of Mopaneveld herbaceous vegetation : an exclosure experiment
(North-West University (South Africa), Potchefstroom Campus, 2015)The herbaceous vegetation layer of the semi-arid Mopaneveld savanna possess a distinctive homogeneity and is highly dynamic in its response to disturbances such as herbivory. Understanding how this ecosystem reacts to ... -
The cultivation and harvesting of micro–algal biomass from the Hartbeespoort Dam for the production of biodiesel
(North-West University, 2011)Renewable energy sources such as biomass are becoming more and more important as alternative to fossil fuels. One of the most exciting new sources of biomass is micro-algae. The Hartbeespoort Dam, located 37 km west of ... -
An econometric analysis of energy poverty and sustainable development in Blantyre (Malawi)
(North-West University, 2013)Energy is the driver of activity in every economy and, therefore, its importance cannot be overemphasised. However, Sub-Saharan Africa (SSA) faces general problems of access to modern energy. Most households and industry ... -
Effect of different plant substrates and growth hormones on the development characteristics and nutrient content of Pleurotus ostreatus in semi-arid conditions
(North-West University (South Africa), Mafikeng Campus, 2017)With the global and local need to identify low-cost sustainable sources of protein and essential minerals for human nutrition the study was undertaken to investigate effect of different plant growth substrates and hormones ... -
Herbaceous plant diversity responses to various treatments of fire and herbivory in sodic patches of a semiarid riparian ecosystem
(2014)Understanding relationships between large herbivores and plant species diversity in dynamic riparian zones, and more specifically sodic zones, is critical to biodiversity conservation. Sodic patches form an integral part ... -
The influence of biomass additions on the pyrolysis behaviour of an inertinite rich South African coal
(North-West University (South Africa), Potchefstroom Campus, 2013)The influences of selected biomasses (hardwood chips, softwood chips, pinewood chips and sugarcane bagasse) on the degradation of an inertinite-rich South African coal were studied. The pyrolysis process is important ... -
Influence of SO2 fumigation on growth, photosynthesis, lipoxygenase and peroxidase activities of soybean (Glycine max), in open–top chambers
(North-West University, 2012)Air pollutant exposure poses a health risk to humans and impacts negatively on agriculture. High levels of air pollution resulted in extensive crop damage and yield reduction in Europe and USA. The Highveld region in South ...
