However, Hall effect measurements showed that the Si activation energy increased in good agreement with the model of a shallow effective mass state donor, with no sudden increase in ED being observed up to x = 0.4. It was then suggested that the increase in the E1 and E2 activation energies, as well as the exciton localisation energies, could be due to the 9 7 valence band crossover, which occurs at roughly the same composition. However, due to the scarcity of reports on the valence band structure in AlxGa1-xN no conclusions could be made at this stage as to the effect of the 9 7 valence band crossover on the PL properties of AlxGa1-xN.]]> Thu 13 May 2021 05:42:11 SAST ]]> An evaluation of Volkswagen of South Africa's graduate training programme to develop a model for achieving programme outcomes http://vital.seals.ac.za:8080/vital/access/manager/Repository/vital:9376 Thu 13 May 2021 05:41:58 SAST ]]> The role of principals in the induction of new educators in their schools http://vital.seals.ac.za:8080/vital/access/manager/Repository/vital:9490 Thu 13 May 2021 05:25:11 SAST ]]> A model for information security management and regulatory compliance in the South African health sector http://vital.seals.ac.za:8080/vital/access/manager/Repository/vital:9740 Thu 13 May 2021 05:16:20 SAST ]]> An analysis of key factors responsible for and influencing the rate of employee absenteeism in the construction sector with specific reference to the Ngqura Harbour project http://vital.seals.ac.za:8080/vital/access/manager/Repository/vital:9263 Thu 13 May 2021 04:51:33 SAST ]]> The market overview and strategy development for selected components of a marketing plan for a cellular provider http://vital.seals.ac.za:8080/vital/access/manager/Repository/vital:10924 Thu 13 May 2021 04:29:31 SAST ]]> Field and laboratory measurements of polarization mode dispersion in optical fibres http://vital.seals.ac.za:8080/vital/access/manager/Repository/vital:10513 Thu 13 May 2021 04:13:15 SAST ]]> Virtuous living towards an African theology of wisdom in the context of the African renaissance http://vital.seals.ac.za:8080/vital/access/manager/Repository/vital:8414 Thu 13 May 2021 04:10:56 SAST ]]> Metalorganic vapour phase epitaxial growth and characterisation of Sb-based semiconductors http://vital.seals.ac.za:8080/vital/access/manager/Repository/vital:10548 Thu 13 May 2021 04:10:03 SAST ]]> The subjective well-being of divorced single custodial parents http://vital.seals.ac.za:8080/vital/access/manager/Repository/vital:9841 Thu 13 May 2021 04:06:53 SAST ]]> A study towards the implementation of a fire service operational structure in the Eden District Municipality area http://vital.seals.ac.za:8080/vital/access/manager/Repository/vital:8597 Thu 13 May 2021 03:58:11 SAST ]]> A SOAP-based Model for secure messaging in a global context http://vital.seals.ac.za:8080/vital/access/manager/Repository/vital:9777 Thu 13 May 2021 03:46:32 SAST ]]> The development of an electrochemical process for the production of para-substituted di-hydroxy benzenes http://vital.seals.ac.za:8080/vital/access/manager/Repository/vital:10367 Thu 13 May 2021 02:38:45 SAST ]]> A pre- and post-test study on the knowledge of grade 6 to 9 learners on HIV/AIDS and sexually transmitted infections http://vital.seals.ac.za:8080/vital/access/manager/Repository/vital:9853 Thu 13 May 2021 02:32:24 SAST ]]> The role of traditional leadership institutions in the development of their communities with specific reference to the Rharhabe kingdom, Mngqesha Great Place, King William's Town http://vital.seals.ac.za:8080/vital/access/manager/Repository/vital:8169 Thu 13 May 2021 02:31:51 SAST ]]> Culture shock the differences between Chinese and South African students at the University of Port Elizabeth http://vital.seals.ac.za:8080/vital/access/manager/Repository/vital:8378 Thu 13 May 2021 02:25:03 SAST ]]> Strategies for sustaining family business through succession planning and family creed http://vital.seals.ac.za:8080/vital/access/manager/Repository/vital:8537 Thu 13 May 2021 02:17:23 SAST ]]> The perceptions of grade eight and nine learners of a life skills programme on HIV/AIDS, sexually transmitted infections, rape and child abuse http://vital.seals.ac.za:8080/vital/access/manager/Repository/vital:9854 Thu 13 May 2021 02:07:59 SAST ]]> An assessment of strategies used to retain nurses in selected hospitals in the Nelson Mandela Metropolitan Municipal area http://vital.seals.ac.za:8080/vital/access/manager/Repository/vital:9260 Thu 13 May 2021 01:42:29 SAST ]]> A study of the use of value based management (VBM) by multinational entities in the Eastern Cape motor industry cluster (ECMIC) http://vital.seals.ac.za:8080/vital/access/manager/Repository/vital:8550 Thu 13 May 2021 01:38:32 SAST ]]> The unfair labour practice relating to benefits http://vital.seals.ac.za:8080/vital/access/manager/Repository/vital:10189 Thu 13 May 2021 01:21:31 SAST ]]> A commercial process development for plant food formulation using polyprotic acids from natural extracts as chelating agents http://vital.seals.ac.za:8080/vital/access/manager/Repository/vital:10368 99.9 % certainty) potential in two of the semi-organic mixtures formulated while the organic mixture showed a relatively good growth rate as compared to the control (pure tap water). According to statistical analysis (ANOVA) comparison, two of the semi-organic mixtures performed considerably better than the two commercial samples evaluated. Potential benefits profoundly associated with these nutrient mixtures as compared to similar liquid fertilizer products on the market is that most nutrients are chelated and dissolved in solution. Also, the mixtures contain all necessary nutrients including plant growth substances required for healthier plant growth. The most important socioeconomic impact is the value addition to the technology chain in the citrus industry. The use of fluid fertilizers in significant quantities is less than twenty years old. Nevertheless, growth has been so rapid that in South Africa demand for mixed liquid fertilizer has greatly increased from 90 000 tons NPK & blended micronutrients in 1955 to more than 600 000 per annum tons today (Report 41/2003, Department of Minerals and Energy). The liquid fertilizers market is sparsely specialized with major competitors like Omnia, Kynoch and Foskor supplying more than 50 % of the market demand. Amongst the nutrient mixtures formulated, mixture one is an NPK (1-1-2) based nutrient mixture containing both secondary nutrients (0.5 % Mg & 1.0 % Ca) and seven micronutrients (0.1 % Fe, 0.05 % Cu, 0.05 % Zn, 0.05 % Mn, 0.02 % B, 0.0005 % Mo and 0.0005 % Co). The composition of this mixture offers the formula a potential to be used as a general purpose (all stages of plant growth) fertilization mixture in view of its balanced composition (containing all essential plant nutrients). Mixture two contains essentially the micronutrients and in higher concentrations (0.3 % Fe, 0.3 % Cu, 0.1 % Zn, 0.2 % Mn, 0.02 % B, 0.0005 % Mo and 0.0005 % Co) as compared to mixture one except for boron, molybdenum and cobalt. The concentration of the micronutrients contained in this mixture is adequately high which offers a potential for it to be used in supplementing nutrition in plants with critical micronutrient-deficient symptoms. Mixture three is very similar to mixture two (1.0 % Fe, 0.05 % Cu, 0.05 % Zn, 0.05 Mn, 0.05 % B, 0.0005 % Mo and 0.0005 % Co) except that the concentrations of all seven micronutrients are considerably less than those of contained in mixture two. However, the concentration of iron in this mixture is as high as 1.0 %. The mixture has a potential to be used in high iron-deficient situations. Mixture four is an organic formula with relatively low nutrient concentrations (NPK-0.02-0.02-1, 0.27 % Mg, 0.02 % Ca, 0.008 % Fe, 0.26 % Cu, 0.012 % Zn, 0.009 % Mn). Nevertheless, this mixture is appealing for organically grown crops where the use of chemicals is prohibited by standards. These lemon juice-based nutrient mixtures were further characterized and tested for stability and storability over a period of eight weeks. This study revealed no major change in the physical quality (colour, pH and “salt out” effect). The basic formulation methodology is a two-step procedure that involves filtration of the lemon juice to remove membranous materials, mixing at ambient temperature and stabilization of the nutrient mixtures. However, for the organic nutrient formula mix, filtration follows after extraction of nutrients from plant materials using the lemon juice.]]> Thu 13 May 2021 01:15:13 SAST ]]> The learning styles of first year university students http://vital.seals.ac.za:8080/vital/access/manager/Repository/vital:9849 Thu 13 May 2021 01:08:16 SAST ]]> A study of the performance of school governing bodies of public schools in the disadvantaged communities of George http://vital.seals.ac.za:8080/vital/access/manager/Repository/vital:9487 Thu 13 May 2021 00:52:06 SAST ]]> Developing a model for establishing, implementing, and maintaining learnerships in South Africa http://vital.seals.ac.za:8080/vital/access/manager/Repository/vital:9377 Thu 13 May 2021 00:47:27 SAST ]]> A study of the barriers to career progress of women in an organisation http://vital.seals.ac.za:8080/vital/access/manager/Repository/vital:8731 Thu 13 May 2021 00:42:41 SAST ]]> The contribution of the Labour Court to the development of strike law http://vital.seals.ac.za:8080/vital/access/manager/Repository/vital:10191 Thu 13 May 2021 00:10:16 SAST ]]> Exploring the developmental profile of Black HIV positive/AIDS infants and children a longitudinal study http://vital.seals.ac.za:8080/vital/access/manager/Repository/vital:9848 Fri 15 Mar 2024 13:04:37 SAST ]]>
