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 ]]> Elucidating Tuta absoluta (Meyrick) invasion and enhancing its management in Eastern Africa : spread, socio-ecological impacts, and potential of a newly imported larval parasitoid for classical biological control Eastern in Africa https://commons.ru.ac.za/vital/access/manager/Repository/vital:41920 Wed 12 May 2021 15:01:32 SAST ]]> A psychobiographical case study: Amelia Dyer in a search for glory https://commons.ru.ac.za/vital/access/manager/Repository/vital:43008 Wed 12 May 2021 15:00:52 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.ru.ac.za/vital/access/manager/Repository/vital:40183 Wed 12 May 2021 14:32:23 SAST ]]> An examination of practices and experiences of teacher educators in the supervision of a national early childhood home based programme https://commons.ru.ac.za/vital/access/manager/Repository/vital:41695 Wed 12 May 2021 14:30:28 SAST ]]> Commercial maritime higher education needs in South Africa https://commons.ru.ac.za/vital/access/manager/Repository/vital:40117 Wed 12 May 2021 14:02:44 SAST ]]> Design of immunosensor for the detection of C-reactive protein using oriented antibody immobilization https://commons.ru.ac.za/vital/access/manager/Repository/vital:41010 Wed 12 May 2021 14:00:32 SAST ]]> Design of Immunobiosensors for Detection of Tumor-Associated Anti-P53 Autoantibodies: Method Development https://commons.ru.ac.za/vital/access/manager/Repository/vital:41002 Wed 12 May 2021 13:59:29 SAST ]]> Socio-ecological, contextual effects in Raven’s Colour Progressive Matrices scores: developing an index for guiding test selection and interpretation https://commons.ru.ac.za/vital/access/manager/Repository/vital:42071 Wed 12 May 2021 13:57:02 SAST ]]> Exploring learners’ proficiency in stoichiometry and attitudes towards science through Process Oriented Guided Inquiry Learning (POGIL) intervention https://commons.ru.ac.za/vital/access/manager/Repository/vital:42474 Wed 12 May 2021 13:51:58 SAST ]]> A comprehensive approach to scalability assessment of ICTD projects : a case study of ICT4RED https://commons.ru.ac.za/vital/access/manager/Repository/vital:42939 Wed 12 Jul 2023 08:28:50 SAST ]]> Participatory mapping, learning and change in the context of biocultural diversity and resilience https://commons.ru.ac.za/vital/access/manager/Repository/vital:1689 Tue 22 Nov 2022 10:29:59 SAST ]]> Catalytic activities of metallophthalocyanines towards detection and transformation of pollutants https://commons.ru.ac.za/vital/access/manager/Repository/vital:4427 Thu 13 May 2021 13:48:05 SAST ]]> Coastal dune ecology and management in the Eastern Cape https://commons.ru.ac.za/vital/access/manager/Repository/vital:4185 Thu 13 May 2021 12:44:59 SAST ]]> A critical analysis of the de-peasantisation process in Nepal with specific reference to the role of state land policies since the 1950s https://commons.ru.ac.za/vital/access/manager/Repository/vital:37667 Thu 13 May 2021 10:59:19 SAST ]]> Development of styrene based imprinted sorbents for selective clean-up of metalloporphyrins in organic media https://commons.ru.ac.za/vital/access/manager/Repository/vital:26580 99 % in selectively extracting the metalloporphyrins. The impact of the template on the affinity of recognition for NTPP was evaluated. The results showed that the NTPP adsorption capacity increased as the molar ratio of NTPP to styrene was increased from 1:1 to 3:1. The optimal ratio of template to functional monomer which yielded the best specific affinity and highest recovery (99.9 %) was 3:1. The effects of trifluoroacetic acid (TFA), dichloromethane (DCM), dimethyl sulphoxide (DMSO), pentane (PEN) on electro-spinnability of the polymer solutions and the morphological appearance of the nanofibers were investigated. The imprinted nanofibers exhibited the same selectivity specialism for both NTPP and VTPP. A remarkable stability in relation to reusability was observed when imprinted nanofibers were used, as they could be reused nine times without incurring any significant loss in removal efficiency. The results were validated by analysing a certified reference material. The imprinted sorbents were therefore found to be selective sorbents that are well suited for handling trace metals in organic media.]]> Thu 13 May 2021 09:54:20 SAST ]]> Pyrroloiminoquinone metabolites from South African Latrunculid sponges https://commons.ru.ac.za/vital/access/manager/Repository/vital:4340 Thu 13 May 2021 08:55:23 SAST ]]> A structural investigation of the sulphated polysaccharide from Aeodes ulvoidea Schmitz https://commons.ru.ac.za/vital/access/manager/Repository/vital:4437 Thu 13 May 2021 07:35:25 SAST ]]> Plastochron index - an indicator of plant structure and function a case study using Pisum sativum L https://commons.ru.ac.za/vital/access/manager/Repository/vital:4183 Thu 13 May 2021 07:33:33 SAST ]]> The evolution of the Lepilemuridae-Cheirogaleidae clade https://commons.ru.ac.za/vital/access/manager/Repository/vital:35989 Thu 13 May 2021 07:31:09 SAST ]]> Modelling the hydrological responses to changes in land use and cover in the Malaba River Catchment, Eastern Uganda https://commons.ru.ac.za/vital/access/manager/Repository/vital:10670 Thu 13 May 2021 07:19:36 SAST ]]> The design, synthesis and antiplasmodial activity of a series of halogenated fosmidomycin analogues and hybrid drugs https://commons.ru.ac.za/vital/access/manager/Repository/vital:28538 Thu 13 May 2021 07:11:33 SAST ]]> A framework for grain commodity trading decision support in South Africa https://commons.ru.ac.za/vital/access/manager/Repository/vital:26925 Thu 13 May 2021 06:52:01 SAST ]]> Anti-diabetic and phytochemical analysis of sutherlandia frutescens extracts https://commons.ru.ac.za/vital/access/manager/Repository/vital:20441 Thu 13 May 2021 06:50:39 SAST ]]> The sustainability of South African construction small, medium and micro enterprises https://commons.ru.ac.za/vital/access/manager/Repository/vital:28194 Thu 13 May 2021 06:39:02 SAST ]]> An analysis of the availability of and access to credit from the formal financial sector and the performance of SMEs https://commons.ru.ac.za/vital/access/manager/Repository/vital:34081 Thu 13 May 2021 06:38:10 SAST ]]> Critical assessment of corruption in municipalities and its impact in service delivery : case study Buffalo City Metropolitan Municipality https://commons.ru.ac.za/vital/access/manager/Repository/vital:27445 Thu 13 May 2021 06:29:39 SAST ]]> Lead-radium dating of two deep-water fishes from the southern hemisphere, Patagonian toothfish (Dissostichus eleginoides) and Orange Roughy (Hoplostethus atlanticus) https://commons.ru.ac.za/vital/access/manager/Repository/vital:5295 1.0 dpm.g⁻¹).

https://commons.ru.ac.za/vital/access/manager/Repository/vital:4309 97 % in selectively extracting the aflatoxins (AFB1, AFB2, AFG1 and AFG2). High reproducibility marked by the low %RSDs of < 1% and low LODs of ≤ 0.02 ng/g were calculated in all cases. The LODs were within the monitoring requirements of the European Commission. The results were validated with a peanut butter certified reference material. The chlorophyll MIP on the other hand selectively removed chlorophyll that would otherwise interfere during pesticide residue analysis (PRA) from > 0.6 to <0.09 Au in green plants extracts. The extracted chlorophyll was removed to far below the level of ≥ 0.399 Au that is usually associated with interference during PRA. Furthermore, the MIP demonstrated better selectivity by removing only chlorophyll (> 99%) in the presence of planar pesticides than the currently employed graphitized carbon black (GCB) that removed both the chlorophyll (> 88%) and planar pesticides (> 89%). For the interfering cholic acid during drug residue analysis, cholic acid MIP electrospun nanofibers demonstrated to be more sensitive and possessing higher loading capacity than the MIP particles. 100% cholic acid was removed by the nanofibers from standard solutions relative to 80% by the particles. This showed that the nanofibers have better performance than the micro particles and as such have potential to replace the particle based SPE sorbents that are currently in use. All the templates were optimally removed from the prepared MIPs by employing a novel pressurized hot water extraction template removal method that was used for the first time in this thesis. The method employed only water, an environmentally friendly solvent to remove templates to ≥ 99.6% with template residual bleeding of ≤ 0.02%.]]> Thu 13 May 2021 01:07:56 SAST ]]> Psychological capital and emotional intelligence as moderators of the relationship between occupational stress and organisational citizenship behaviour among graduate employees in Nigeria https://commons.ru.ac.za/vital/access/manager/Repository/vital:33250 Thu 13 May 2021 00:51:21 SAST ]]> Trophodynamics of the benthic and hyperbenthic communities inhabiting the Sub-Antarctic Prince Edward Islands : stable isotope and fatty acid signatures https://commons.ru.ac.za/vital/access/manager/Repository/vital:5806 Thu 13 May 2021 00:46:22 SAST ]]> Contributions to the biology, anatomy and physiology of Opisthophthalmus Latimanus & other scorpions https://commons.ru.ac.za/vital/access/manager/Repository/vital:5891 Thu 13 May 2021 00:36:00 SAST ]]> An empirical phenomenological investigation of procrastinating behaviour https://commons.ru.ac.za/vital/access/manager/Repository/vital:2929 Thu 13 May 2021 00:13:14 SAST ]]> Neuropharmacological interactions in the rat pineal gland a study of antidepressant drugs https://commons.ru.ac.za/vital/access/manager/Repository/vital:3744 Thu 13 May 2021 00:05:50 SAST ]]> Evaluation of some pharmaceutical and personal care products and pesticide residues in selected wastewater treatment plants and receiving watersheds in Eastern Cape, South Africa https://commons.ru.ac.za/vital/access/manager/Repository/vital:28138 Thu 13 May 2021 00:04:32 SAST ]]> Data compression, field of interest shaping and fast algorithms for direction-dependent deconvolution in radio interferometry https://commons.ru.ac.za/vital/access/manager/Repository/vital:21089 Fri 07 Jul 2023 06:30:13 SAST ]]> Development of an enzyme-synergy based bioreactor system for the beneficiation of apple pomace lignocellulosic waste https://commons.ru.ac.za/vital/access/manager/Repository/vital:19947 Fri 06 Aug 2021 11:40:35 SAST ]]> Decentralization and quality assurance in the Ugandan primary education sector https://commons.ru.ac.za/vital/access/manager/Repository/vital:26897 Fri 06 Aug 2021 09:57:38 SAST ]]>
