The impact of different storage temperatures and storage period on the antioxidant activity of pomegranate
(University of Western Cape, 2021)Fruit storage at cold temperatures is normally used to delay decay while maintaining the fruit’s quality. However, storage at low temperatures for a prolonged period causes some important metabolic functions within the ... -
The impact of environment and mergers on the H I content of galaxies in hydrodynamic simulations
(University of the Western Cape, 2015)We quantitatively examine the effects of merger and environment within a cosmological hydrodynamic simulation. We show that our simulation model broadly reproduces the observed scatter in H I at a given stellar mass as ... -
The impact of HIV/AIDS on poverty in the Eastern Cape: a case study of Lusikisiki
(University of the Western Cape, 2007)In recent publications and reports it has been outlined that HIV/AIDS is growing rapidly in the rural communities and the levels of poverty are on the increase. HIV/AIDS has been viewed to have a disastrous impact in almost ... -
The impact of land use and land cover changes on wetland productivity and hydrological systems in the Limpopo transboundary river basin, South Africa
(University of Western Cape, 2021)Wetlands are highly productive systems that act as habitats for a variety of flora and fauna. Despite their ecohydrological significance, wetland ecosystems are under severe threat as a result of environmental changes (e.g. ... -
The impact of nanoparticles on the proteome of cultured human cells
(2021)Living organisms are constantly being exposed to nanoparticles (NPs) in the environment via air, water, soil. Routes of exposure are usually in the form of industrial, occupational exposure, as well as therapeutic ... -
The impact of Niacin on PCSK9 levels in vervet monkeys (Chlorocebus aethiops)
(University of the Western Cape, 2020)Cardiovascular diseases (CVDs) such as ischaemic heart diseases, heart failure and stroke remain a major cause of death globally. Various deep-rooted factors influence CVD development; these include but are not limited ... -

The impact of storage time and seasonal harvesting on biomarker levels of lessertia frutescens
(University of Western Cape, 2012)In South Africa, it is estimated that approximately 70% of the population frequently make use of traditional medicinal plants for their health care needs. The use of Lessertia frutescens by the various cultural groups in ... -
The impact of universal health coverage and national health expenditure on the main health determinants on central America countries and the Caribbean
(University of Western Cape, 2020)Health is considered as a sensitive marker of the sustainable development of a population. In Central America and Caribbean (CAC) region, the majority of countries are considered middle-income economies with significant ... -
The impact of using technology through cooperative learning on learners’ performance on grade 11 circle geometry
(University of the Western Cape, 2019-11)Euclidean geometry was recently re-introduced as a compulsory topic in the Mathematics Curriculum for learners in the Further Education and Training (FET) band in 2012. The diagnostic analysis reports on the National ... -
Impact of vanadium stress on physiological and biochemical characteristics in heavy metal susceptible and tolerant Brassicaceae
(University of the Western Cape, 2013)There is an influx in heavy metals into soils and ground water due to activities such as increased mineral mining, improper watering and the use of heavy metal contaminated fertilizers. These heavy metals are able to ... -
Impacts and control of alien Proteaceae invasion in the Western Cape Province, South Africa
(University of the Western Cape, 2017)Research focused on ecological impacts and control of invasive alien species (IAS) is gaining attention worldwide. The eradication and control of invasive alien plants (IAP) is essential for the restoration of native plant ... -
The impacts of channelisation on the geomorphology and ecology of the Kuils River, Western Cape, South Africa
(University of Western Cape, 2003)Urbanisation and storm water input in the Kuils River catchment changed the flow of the river from ephemeral to perennial. This led to flooding problems in the Kuilsrivier central business district. The river was channelised ... -
Impacts of degradation on critically endangered Oudtshoorn Gannaveld
(2010)In the Succulent Karoo biome of South Africa vegetation degradation by overgrazing is a recognized threat to biodiversity. In the eastern Little Karoo region of the Western Cape Province, ostrich farming has degraded large ... -
Impacts of the invasive reed Arundo donax on biodiversity at the community-ecosystem level
(University of the Western Cape, 2007)Arundo donax is an invasive species that mostly impacts on sensitive riparian ecosystems. Arundo is also invasive in South Africa, though less is known about its ecology, biology, and impacts. Since California and the ... -
Impedimetric and electrode kinetic dynamics of DNA aptamer nanobiosensors for estrogeneous endocrine disruptors
(University of the Western Cape, 2011)In this work, DNA aptamer biosensor systems were developed for the detection of l7p-estradiol - an estrogeneous endocrine disrupting chemical (EDC). Endocrine disrupting chemicals are group of compounds that impact negatively ... -
The implementation of in vitro assays to screen environmental samples for male reproductive toxicity
(University of the Western Cape, 2010)Endocrine disrupting compounds (EDCs) are exogenous compounds/chemicals which interfere with, or have adverse effects on the production, distribution and function of natural hormones, thereby affecting normal endocrine ... -
