The performance evaluation of MIDAS compared with ANNs to reconstruct storm-time TEC over the African low- and mid-latitude regions showed that MIDAS and ANNs provide comparable results. Their respective mean absolute error (MAE) values were 4.81 and 4.18 TECU. The ANN model was, however, found to perform 24.37 % better than MIDAS at estimating storm-time TEC for low latitudes, while MIDAS is 13.44 % more accurate than ANN for the mid-latitudes. When their performances are compared with the IRI model, both MIDAS and ANN model were found to provide more accurate storm-time TEC reconstructions for the African low- and mid-latitude regions. A comparative study of the performances of EOF, NLRA, ANN, and IRI models to estimate TEC during geomagnetic storm conditions over various latitudes showed that the ANN model is about 10 %, 26 %, and 58 % more accurate than EOF, NLRA, and IRI models, respectively, while EOF was found to perform 15 %, and 44 % better than NLRA and IRI, respectively. It was further found that the NLRA model is 25 % more accurate than the IRI model. We have also investigated for the first time, the role of meridional neutral winds (from the Horizontal Wind Model) to storm-time TEC modelling in the low latitude, northern and southern hemisphere mid-latitude regions of the African sector, based on ANN models. Statistics have shown that the inclusion of the meridional wind velocity in TEC modelling during geomagnetic storms leads to percentage improvements of about 5 % for the low latitude, 10 % and 5 % for the northern and southern hemisphere mid-latitude regions, respectively. High-latitude storm-induced winds and the inter-hemispheric blows of the meridional winds from summer to winter hemisphere have been suggested to be associated with these improvements.]]> Wed 12 May 2021 19:12:42 SAST ]]> Culturally-informed coping strategies of posttraumatic stress disorders among the black Africans in the greater Accra region of Ghana and black Africans in the eastern cape of South Africa https://commons.ufh.ac.za/vital/access/manager/Repository/vital:38154 Wed 12 May 2021 19:07:19 SAST ]]> Investigating and expanding learning across activity system boundaries in improved cook stove innovation diffusion and adoption in Malawi https://commons.ufh.ac.za/vital/access/manager/Repository/vital:29212 Wed 12 May 2021 19:02:04 SAST ]]> I want them to be confident, to build an argument: an exploration of the structure of knowledge and knowers in Political Studies https://commons.ufh.ac.za/vital/access/manager/Repository/vital:30719 Wed 12 May 2021 18:55:43 SAST ]]> In-betweenness: a postcolonial exploration of sociocultural intergenerational learning through cattle as a medium of cultural expression in Mpembeni, KwaZulu-Natal https://commons.ufh.ac.za/vital/access/manager/Repository/vital:29213 Wed 12 May 2021 18:45:16 SAST ]]> Data quality issues in electronic health records for large-scale databases https://commons.ufh.ac.za/vital/access/manager/Repository/vital:38145 Wed 12 May 2021 18:42:26 SAST ]]> Expanding learning in clergy leadership formation in an Anglican Church Province in Southern Africa: a critical realist study https://commons.ufh.ac.za/vital/access/manager/Repository/vital:30704 Wed 12 May 2021 18:19:30 SAST ]]> Enumeration, conformation sampling and population of libraries of peptide macrocycles for the search of chemotherapeutic cardioprotection agents https://commons.ufh.ac.za/vital/access/manager/Repository/vital:34293 Wed 12 May 2021 17:42:00 SAST ]]> Innovation: its impact on the success of construction micro, small, and medium enterprises in Northern Nigeria https://commons.ufh.ac.za/vital/access/manager/Repository/vital:38130 Wed 12 May 2021 16:50:04 SAST ]]> Plants, people, and place: complex, mutualistic, and co-evolving global patterns through time https://commons.ufh.ac.za/vital/access/manager/Repository/vital:30609 Wed 12 May 2021 16:17:38 SAST ]]> Photophysical properties and photodynamic therapy activities of symmetrical and asymmetrical porphyrins embedded into Pluronic polymer micelles and nonlinear optical properties of an asymmetrical phthalocyanine https://commons.ufh.ac.za/vital/access/manager/Repository/vital:29122 90% cell survival.

The model chi-square value of 43.47 (approximately 44% ) was significant. Thus, the indication is that the model has a good fit in predicting the possibility of a fuel retail outlet being located in the core or peripheral zone of the metropolis as determined by the explanatory variables (the independent variables accounted for about 44% of possible factors which determined whether a fuel retail outlets is located either within the core or peripheral zones of the metropolis. The remaining 56% are factors not considered in the study). The result gotten from the in depth interview sessions corroborated the findings from the tested hypothesis. The third objective was to examine the effects which the supply chain technique employed (either vertically integrated model or third-party arrangement) has on the achievement of efficient and effective distribution of the products. In order to achieve this objective, all the 389 registered members of Petroleum Tanker Drivers (PTD) association who are members of the PTD in the metropolis were sampled, 265 (around 70%) of the distributed questionnaires were retrieved and used for the analysis. In depth interview sessions were also conducted with three different managers of the three major conglomerates in the downstream sector of the Nigerian petroleum sector. The result of one-way between subjects (ANOVA) which was conducted to compare differences in the management and performances of haulage services outsourced to the 3PLS and those run under VIM showed that there was a significant effect of ownership type on management performance (F (2,262) = 60.26, p<.05). The null hypothesis was therefore rejected while the alternate hypothesis was accepted. The findings from the interview sessions posted similar results. The fourth and final objective was to analyze the effect that the socio-economic attributes of the participants (haulers and managers of retail outlets) involved in the distribution of xxvi petroleum products has on the safe, efficient and cost-effective distribution of product and this was done through the use of descriptive statistics, inferential statistics and incisive analysis of the interview sessions. A total number of 265 (70%) out of the 389 registered members of Petroleum Tanker Driver Association (PTDA) participated in the study. Multiple regression analysis (MRA) was used to test this hypothesis. The result from the statistical analysis show that the use of stimulant, work condition, marital status and educational attainment/literacy level have joint influence on compliance (R2 = 0.31, F (4,260) = 29.72, p<.05). On the basis of the foregoing, the hypothesis is thus accepted. The result from the interview sessions confirmed the existence of strong relationship between the explanatory variables and the hypothetical dependant variable. The study recommended a review of the planning processes guiding the establishment of fuel retail outlets. The study also advocated that retailers should endeavour to have stronger control over the supply chain of their products this could done by investing more in VIM rather than outsourcing such functions to 3PLs. This will help in better business performances. Government agencies in charge of monitoring drug abuse among haulers are advised to be more proactive by the duo of prevention and punishment strategies. This should include advocacy campaign against drug abuse. Different ranges of punishments should also be meted out for individual haulers found culpable.]]> Wed 12 May 2021 15:06:55 SAST ]]> Application of some missing data techniques in estimating missing data in high blood pressure covariates https://commons.ufh.ac.za/vital/access/manager/Repository/vital:40195 Wed 12 May 2021 15:06:06 SAST ]]> Ontological Model for Xhosa Beadwork in Marginalised Rural Communities: A Case of the Eastern Cape https://commons.ufh.ac.za/vital/access/manager/Repository/vital:40516 Wed 12 May 2021 15:05:06 SAST ]]> Electrical, photo-thermal and mechanical degradation analysis of degraded single junction amorphous silicon solar modules https://commons.ufh.ac.za/vital/access/manager/Repository/vital:40204 Wed 12 May 2021 15:01:15 SAST ]]> Diversity, host plant range and ecology of Lepidoptera stem borers in South Africa https://commons.ufh.ac.za/vital/access/manager/Repository/vital:40405 Wed 12 May 2021 14:44:25 SAST ]]> Patriarchy and the participation of women in Zimbabwean national politics: a study of selected women Politicians in Matabeleland Region https://commons.ufh.ac.za/vital/access/manager/Repository/vital:41082 Wed 12 May 2021 14:36:28 SAST ]]> Communication barriers within virtual communities in an ethnoreligious diverse society: a case study of Nigeria https://commons.ufh.ac.za/vital/access/manager/Repository/vital:40533 Wed 12 May 2021 14:36:01 SAST ]]> Challenges faced by grandparents in caring for their grandchildren in Mdlankomo location, Libode, Eastern Cape https://commons.ufh.ac.za/vital/access/manager/Repository/vital:40692 Wed 12 May 2021 14:33:53 SAST ]]> Medicinal Plants Used to Treat and Manage Respiratory Infections in the Limpopo Province, South Africa: Phytotherapeutic Study of Bapedi Traditional Healers’ Practices https://commons.ufh.ac.za/vital/access/manager/Repository/vital:40512 Wed 12 May 2021 14:31:04 SAST ]]> Impact of adoption of drought tolerant maize varieties on yield in the face of climate change: A case of Salima, Chikwawa and Karonga districts, Malawi https://commons.ufh.ac.za/vital/access/manager/Repository/vital:40491 Wed 12 May 2021 14:30:31 SAST ]]> Exploring the interplay of sociolinguistic factors in the teaching of esl at secondary school level in Zimbabwe https://commons.ufh.ac.za/vital/access/manager/Repository/vital:40522 Wed 12 May 2021 14:28:53 SAST ]]> Evaluation of pre-treatment methods on production of bioethanol from bagasse and sugarcane trash https://commons.ufh.ac.za/vital/access/manager/Repository/vital:40403 Wed 12 May 2021 14:25:03 SAST ]]> Land rental policy and land market in Mashonaland East Province, Zimbabwe: implications on farmer decisions, efficiency and equity under A1 and A2 models https://commons.ufh.ac.za/vital/access/manager/Repository/vital:40501 Wed 12 May 2021 14:22:16 SAST ]]> Listening to silenced voices: The lived experiences of Xhosa mothers during the initiation period of their sons https://commons.ufh.ac.za/vital/access/manager/Repository/vital:40529 Wed 12 May 2021 14:19:33 SAST ]]> Land Reform and the Challenge of Rural Development in Zimbabwe: The Case of the Fast Track Reform in Mashonaland West Region https://commons.ufh.ac.za/vital/access/manager/Repository/vital:42704 Wed 12 May 2021 14:09:11 SAST ]]> A critical assessment of the implementation of community development projects in mitigating youth unemployment: A case of Mashonaland West province Zimbabwe https://commons.ufh.ac.za/vital/access/manager/Repository/vital:41079 Wed 12 May 2021 14:08:51 SAST ]]> Ict literacy skills and demographic factors as determinants of electronic resources use among the undergraduate students in the selected universities the Eastern Cape, South Africa https://commons.ufh.ac.za/vital/access/manager/Repository/vital:40675 0.05) shows weak evidence against the null hypothesis, so you reject the null hypothesis i.e. X2 (3, N=53) = 7.82.

Therefore, the explanation is that age has no influence on access of respondents to electronic resources through cybercafé. In order to make ICT literacy skills more beneficial to the undergraduate students in the selected HEIs, recommendations were made in this study. Firstly, there is a need for mass enlightenment campaigns on the use and benefits of E-resources among undergraduate respondents, the building of capacity of the undergraduate students in the use of electronic resources ICT literacy skill development programmes, need for intervention programmes focusing on the application xiii of some E-resources and software where the students are ranked low.

In sensory evaluation, consumers indicated how they would prefer to pay premium for meat with guaranteed muscle and fat colour, low fat content, high marbling and tenderness. Consumers observed breed differences (P<0.05) in muscle fibre separation and muscle colour. The overall liking of each attribute was more on moderate bright cherry red lean colour, moderate yellow fat, very abundant marbling and slight separation of muscle fibres. Differences on discrete liking of each attribute among consumers had an effect on the overall liking of each steak with Hereford steaks being more preferred by consumers. It was concluded that meat from beef animals within the same feeding regime has a different fatty acid composition owing to different breed synthetic pathways and feed ingredients and that meat tenderness is not affected by the muscle nanostructure early post-mortem. However, during ageing, meat tenderness is directly linked to breed related myofibril structure changes in particular the myofibril diameter, spacing between myofibrils and their interaction; while the muscle texture features, fibre diameter, spacing between muscle fibres and sarcomere length explain the non-uniformity of beef tenderness. Also the organoleptic and health related quality of meat assumed more importance among consumers in sensory evaluation. Thus meat classification systems should include more credence aspects or indicators that support credence quality of meat]]> Wed 12 May 2021 13:57:19 SAST ]]> Incidence of cholera-causing and non cholera-causing pathogenic vibrio species in the river-k and two of its feeder wastewater treatment plants in the Raymond Mhlaba municipality, Eastern Cape province of South Africa https://commons.ufh.ac.za/vital/access/manager/Repository/vital:40190 Wed 12 May 2021 13:56:35 SAST ]]> Local web news as tools for framing food security: the content analysis of four selected Eastern Cape web newspapers https://commons.ufh.ac.za/vital/access/manager/Repository/vital:41080 Wed 12 May 2021 13:55:00 SAST ]]> Genetic characteristics of Human Immunodeficiency Virus-1, and deter-minants of late presentation for care and Diabetes mellitus amongst newly diagnosed Human Immunodeficiency Virus positive patients in the Eastern Cape, South Africa. https://commons.ufh.ac.za/vital/access/manager/Repository/vital:40495 Wed 12 May 2021 13:54:22 SAST ]]> Nutritional quality of sausage made with edible meat waste and the perception of consumers on offal product in Eastern Cape Province, South Africa https://commons.ufh.ac.za/vital/access/manager/Repository/vital:40094 Wed 12 May 2021 13:45:00 SAST ]]> Ph-responsive liposomal systems for site-specific pulmonary delivery of anti-tubercular drugs https://commons.ufh.ac.za/vital/access/manager/Repository/vital:35822 Wed 04 Aug 2021 14:30:34 SAST ]]> La masculinité dans quelques oeuvres des romanciers Francophones Africains https://commons.ufh.ac.za/vital/access/manager/Repository/vital:31446 Tue 28 Feb 2023 08:54:05 SAST ]]> Governing pregnancy in South Africa: political and health debate, policy and procedures https://commons.ufh.ac.za/vital/access/manager/Repository/vital:30600 Tue 15 Aug 2023 15:50:21 SAST ]]> Application of computational methods in elucidating the isomerization step in the biosynthesis of coumarins https://commons.ufh.ac.za/vital/access/manager/Repository/vital:29124 Tue 11 Jul 2023 16:25:27 SAST ]]> Genetic diversity, resistance profile of hiv and risk assessment of mother-to-child transmission in pregnant women on antiretroviral therapy in the Eastern Cape, South Africa https://commons.ufh.ac.za/vital/access/manager/Repository/vital:40183 Tue 07 May 2024 11:09:10 SAST ]]> Effects of pre-slaughter stress, sex and breed on blood stress indicators, heat shock proteins, glycolytic potential and lamb quality https://commons.ufh.ac.za/vital/access/manager/Repository/vital:40402 Tue 07 May 2024 10:54:04 SAST ]]> Effect of social capital and information acquisition on the adoption and benefits of conservation agriculture among cassava and maize smallholder farmers in South-West Nigeria https://commons.ufh.ac.za/vital/access/manager/Repository/vital:40200 Tue 07 May 2024 09:51:06 SAST ]]> A physiological study on a commercial reef fish to quantify the relationship between exploitation and climate change resilience https://commons.ufh.ac.za/vital/access/manager/Repository/vital:30599 Thu 29 Sep 2022 14:23:25 SAST ]]> CubiCal: a fast radio interferometric calibration suite exploiting complex optimisation https://commons.ufh.ac.za/vital/access/manager/Repository/vital:30711 Thu 13 May 2021 15:04:39 SAST ]]> An investigation into the performance of smallholder irrigation schemes in Limpopo Province, South Africa: success factors, typologies and implications for development https://commons.ufh.ac.za/vital/access/manager/Repository/vital:30709 150% intensity) were old gravity schemes. Farmers on approximately 75% of Limpopo smallholder schemes are currently engaging in land exchange transactions in a highly insecure and un-formalised institutional setup. Land exchange prevalence longer than two years was moderately associated with cropping intensity and strongly associated with commercialisation. This result has three important implications. First, it suggests that more land is utilised on the schemes when there is vibrant land-leasing activity. Secondly, schemes with a higher prevalence of long-term leasing seem to have a strong tendency to be more commercialised. Thirdly, the duration of the lease is significant, as neither single-season, nor annual leases yielded any positive associations, while those exchanges that were two years or longer, were associated with increased performance. These findings highlight the potential for longer-term land-exchange interventions to address the widespread low land utilisation on smallholder schemes, and to catalyse more commercially-oriented farming. An irrigation scheme typology was derived from the cluster analysis and was aligned to a contemporary irrigation farming typology. The key descriptors included technology type, purpose of farming and scheme management type. By matching scheme type to the farmer typology (or typologies), strategic decisions regarding technology choices for infrastructure, land, and water institutional interventions can be better informed. All schemes demand attention to the multiple factors required to achieve performance, not least water-tenure security, irrigation management organisational development, and infrastructure modernisation. Complexity was demonstrated by the finding that multiple factors contribute to success, and that there are many dimensions that change independently and have a cascading effect through the system in ways that are difficult to predict. Agricultural systems support to achieve productivity and profitability are essential for success. The research findings lead to the recommendation that, in addition, strategic planners must also consider the implications of the dominant factors of water-technology choices so that these are manageable, and the dynamics of farm-size change based on land exchange processes, in order to harness new opportunities to maximise irrigation scheme performance in future.]]> Thu 13 May 2021 11:26:49 SAST ]]> Physicochemical properties and photodynamic therapy activities of indium and zinc phthalocyanine-nanoparticle conjugates https://commons.ufh.ac.za/vital/access/manager/Repository/vital:30589 50Îll viability at concentrations≤ 160μg/mL, however the conjugates showed<50% cell viabilityatconcentrations≤ 160μg/mLprobably due to the enhanced singlet oxygen quantum yield.

We find the leakage due to a population of point sources to be 12% lower than the prediction from our polarized model.]]> Thu 13 May 2021 05:43:39 SAST ]]> Construction material logistics management: the case of North-Central Nigeria https://commons.ufh.ac.za/vital/access/manager/Repository/vital:38132 Thu 13 May 2021 05:24:24 SAST ]]> Challenges of subsistence farming in South Africa: a case study of Emjkweni village in Eastern Cape Province https://commons.ufh.ac.za/vital/access/manager/Repository/vital:38142 Thu 13 May 2021 04:55:59 SAST ]]> Pyramidal deliberative democracy https://commons.ufh.ac.za/vital/access/manager/Repository/vital:30309 Thu 13 May 2021 04:50:05 SAST ]]> Employee talent management in the Uganda health sector: a public institutions perspective https://commons.ufh.ac.za/vital/access/manager/Repository/vital:36578 Thu 13 May 2021 04:48:42 SAST ]]> #KeepItReal: discursive constructions of authenticity in South African consumer culture https://commons.ufh.ac.za/vital/access/manager/Repository/vital:28641 Thu 13 May 2021 04:24:57 SAST ]]> Ecological assessment and biogeography of coastal vegetation and flora in southern Mozambique https://commons.ufh.ac.za/vital/access/manager/Repository/vital:36280 Thu 13 May 2021 04:21:00 SAST ]]> Digital colonialism: South Africa’s education transformation in the shadow of Silicon Valley https://commons.ufh.ac.za/vital/access/manager/Repository/vital:30936 Thu 13 May 2021 04:03:21 SAST ]]> Applying anthropological perspectives in criminal procedures involving murder in Port Elizabeth, 2000-2016 https://commons.ufh.ac.za/vital/access/manager/Repository/vital:38161 Thu 13 May 2021 03:49:40 SAST ]]> A multi-threading software countermeasure to mitigate side channel analysis in the time domain https://commons.ufh.ac.za/vital/access/manager/Repository/vital:29790 Thu 13 May 2021 03:46:18 SAST ]]> A social realist account of constraints and enablements navigated by South African students during the four year professional accounting programme at Rhodes University, South Africa https://commons.ufh.ac.za/vital/access/manager/Repository/vital:30946 Thu 13 May 2021 03:38:01 SAST ]]> Innovative management in the South African public service: a case of the Department Of Health in Limpopo province https://commons.ufh.ac.za/vital/access/manager/Repository/vital:35981 Thu 13 May 2021 03:25:19 SAST ]]> Examination of teacher mediation and its impact on foundational reading skills in Grade-R classrooms in Namibia https://commons.ufh.ac.za/vital/access/manager/Repository/vital:30700 Thu 13 May 2021 03:23:30 SAST ]]> Occurrence, feeding ecology, and population structure of two dolphin species, Tursiops aduncus and Delphinus delphis, off the Wild Coast of South Africa https://commons.ufh.ac.za/vital/access/manager/Repository/vital:34197 70% of total counts) of sightings were made inside the MPAs. Short-term boat-based surveys were conducted three times a year between June 2014 and December 2016, contributing to a total of 47 days of surveys divided into three locations: Amathole, Hluleka, and Pondoland, each containing a MPA. Density and group size data were analyzed for both species and photographic identification analysis was performed for photographs of bottlenose dolphin dorsal fins. Results indicate that animal and sighting density did not differ temporally (bottlenose dolphin: sighting density – p=0.398, individual density –p=0.781; common dolphin: sighting density –p=0.472, individual density – p=0.204). Environmental factors (sea surface temperature, depth, substrate, and distance from shore) appeared to have limited effect on individual and sighting density and group size for both species (p>0.05). Photographic identification of bottlenose dolphins resulted in 2149 individuals, with a 11.8% resighting rate, with the highest resighting rate within the Pondoland MPA (16.1%). The resighting count did not differ temporally between monthly survey based on generalized linear models (p=0.866), but did differ between study areas (p<0.0001). These results provide the first evidence of the occurrence of both species of dolphin off the Wild Coast, as they were sighted in this region in all survey months. There was no trend in density based on temporal or environmental factors, which suggests other factors are influencing their occurrence. Resightings of bottlenose dolphins within the area suggest that there is some degree of residency, though the majority of animals were only sighted on a single occasion and there was no plateau in the discovery curve. A total of 256 biopsy samples (bottlenose dolphins =128; common dolphins=128) were collected during boat-based surveys. Bottlenose dolphin samples were also collected from adjacent areas to the southwest (Algoa Bay, n=22) and northeast (KwaZulu-Natal (KZN), n=20) of the Wild Coast to investigate similarities and differences between these areas. Despite a high degree of niche overlap between the two species (41%), common dolphins fed with a broader niche (standard ellipse area probability 0.89) than bottlenose dolphins in the summer and a narrower niche in the winter (probability 0.94). There was a clear spatial variation in the diet of bottlenose dolphins along the coast, with individuals from Algoa Bay and Amathole demonstrating 0% niche overlap with individuals from KZN, but the mechanism for these differences remains unclear as other species from South African waters demonstrate a strong southwest to northeast gradient in nitrogen for the Eastern Cape coastline. This research provides valuable baseline information regarding dolphins off the Wild Coast of South Africa, which remained largely unknown. My results indicate that bottlenose dolphins may be more resident in the Wild Coast than previous predicted, and confirm that common dolphins are highly mobile in this area.]]> Thu 13 May 2021 03:09:09 SAST ]]> Energy yield modelling and analysis of photovoltaic systems in Namibia https://commons.ufh.ac.za/vital/access/manager/Repository/vital:35287 Thu 13 May 2021 03:09:01 SAST ]]> A sociological understanding of urban governance and social accountability: the case of Bulawayo, Zimbabwe https://commons.ufh.ac.za/vital/access/manager/Repository/vital:29860 Thu 13 May 2021 02:37:59 SAST ]]> A gatherer’s paradise? early humans and plant foraging on the Cape south coast, South Africa https://commons.ufh.ac.za/vital/access/manager/Repository/vital:34124 Thu 13 May 2021 02:13:18 SAST ]]> Reading to learn for secondary schooling: an interventionist action research study within a South African under-privileged setting https://commons.ufh.ac.za/vital/access/manager/Repository/vital:30706 Thu 13 May 2021 02:01:40 SAST ]]> A critical realist exploration of the culture of resistance in educational technology integration practices at a South African university https://commons.ufh.ac.za/vital/access/manager/Repository/vital:30033 Thu 13 May 2021 01:51:14 SAST ]]> Genetic characterisation of a range of geographically distinct Helicoverpa armigera nucleopolyhedrovirus (HearNPV) isolates and evaluation of biological activity against South African populations of the African bollworm, Helicoverpa armigera (Hu bner) (Lepidoptera: Noctuidae) https://commons.ufh.ac.za/vital/access/manager/Repository/vital:31426 Thu 13 May 2021 01:45:56 SAST ]]> Civil society engagement with water governance at a local government scale in South Africa https://commons.ufh.ac.za/vital/access/manager/Repository/vital:39051 Thu 13 May 2021 01:36:45 SAST ]]> Learning to learn: a critical realist exploration into the home established learning practices of a marginalised community in Port Elizabeth https://commons.ufh.ac.za/vital/access/manager/Repository/vital:30939 Thu 13 May 2021 01:36:33 SAST ]]> Accountability deficits in local government in South Africa: implications for social and economic development https://commons.ufh.ac.za/vital/access/manager/Repository/vital:36879 Thu 13 May 2021 01:12:28 SAST ]]> Elucidating the Molecular Basis of the Interaction between the β2-integrin, αXβ2, and the low-affinity IgE Receptor, CD23 https://commons.ufh.ac.za/vital/access/manager/Repository/vital:34277 Thu 13 May 2021 01:03:28 SAST ]]> Perspectives on land and water politics at Mushandike Irrigation Scheme, Masvingo, Zimbabwe https://commons.ufh.ac.za/vital/access/manager/Repository/vital:30573 Thu 13 May 2021 00:45:03 SAST ]]> Elasticity of the South African economy towards portfolio investments in BRICS countries https://commons.ufh.ac.za/vital/access/manager/Repository/vital:38141 Thu 13 May 2021 00:36:54 SAST ]]>
