The expected preference for endo-alkylation is supported by NMR (chemical shift, coupling constant and NOE) data and was confirmed by acidic hydrolysis of the pentylated 3-imino lactone to afford the known acid. Computer modelling, with the software package HYPERCHEM®, was used to explore the conformational properties of the alkylated products and their enolate precursors. Exploratory work on the enantiomeric beneficiation of racemic amino acids, using alkylated imino lactone derivatives, revealed preferential exo-protonation of the enolate intermediates. Asymmetric Baylis-Hillman reactions between a novel camphor-derived acrylic ester and a range of aldehydes afforded the corresponding 2-(hydroxyalkyl)acrylates in up to 59% d.e., the observed stereoselectivities being sensitive to both steric and electronic factors. Attempts to prepare imino lactone derivatives from ketopinic acid, although unsuccessful, led to the isolation of two novel W-(carbobenzyloxy)glycinates, whose structures were established by 1- and 2-D NMR spectroscopy. Attempts to prepare "BINAP" analogues from dibomyl ether's also proved unsuccessful, but the investigation led to the discovery of a third, novel dibomyl ether.]]> Tue 09 Nov 2021 15:33:35 SAST ]]> An exploration of the mathematical learner identities of high school learners who participated in after school mathematics clubs in primary school https://commons.ru.ac.za/vital/access/manager/Repository/vital:44953 Tue 08 Feb 2022 09:15:36 SAST ]]> Climate for changing lenses: Reconciliation through site-specific, media arts-based environmental education on the water and climate change nexus in South Africa and Canada https://commons.ru.ac.za/vital/access/manager/Repository/vital:45260 Tue 05 Jul 2022 12:52:40 SAST ]]> Computational analysis of known drug resistant mutants of Plasmodium falciparum Dihydrofolate Reductase (PfDHFR) and screening for novel antifolates against the enzyme https://commons.ru.ac.za/vital/access/manager/Repository/vital:50170 Thu 21 Apr 2022 17:19:02 SAST ]]> Diversified computational approaches for the identification of orthosteric drugs, allosteric modulators and unveiling drug resistance mechanisms: application to infectious diseases https://commons.ru.ac.za/vital/access/manager/Repository/vital:50169 Thu 21 Apr 2022 17:09:08 SAST ]]> A sociological analysis of the experiences of Zimbabwean teachers in South Africa: the case of KwaZulu-Natal townships and township secondary schools https://commons.ru.ac.za/vital/access/manager/Repository/vital:65805 Thu 20 Jul 2023 13:00:00 SAST ]]> A systems thinking approach to e-government strategy formulation for water service delivery in South African local municipalities https://commons.ru.ac.za/vital/access/manager/Repository/vital:28547 Thu 20 Apr 2023 12:18:21 SAST ]]> Culture, gender and forests: social differentiation in coping and adapting to climate change and other stressors in the south west and east regions of Cameroon https://commons.ru.ac.za/vital/access/manager/Repository/vital:57284 Thu 13 Oct 2022 09:36:46 SAST ]]> Ethics of climate change: a normative account https://commons.ru.ac.za/vital/access/manager/Repository/vital:45272 Thu 13 Oct 2022 08:40:40 SAST ]]> Development of biosensor systems for the detection of anti-cancer drugs and prostate cancer https://commons.ru.ac.za/vital/access/manager/Repository/vital:65803 Thu 13 Jul 2023 15:14:29 SAST ]]> Characterisation of two novel ferrocenyl benzoxazines as in vitro triple-negative breast cancer inhibitors https://commons.ru.ac.za/vital/access/manager/Repository/vital:65776 Thu 13 Jul 2023 10:47:08 SAST ]]> Bioprospecting for amylases, cellulases and xylanases from ericoid associated fungi, their production and characterisation for the bio-economy https://commons.ru.ac.za/vital/access/manager/Repository/vital:28533 Thu 09 Mar 2023 09:44:15 SAST ]]> A critical analysis of the Urban Food System, Urban Governance and Household Food Security in Bulawayo, Zimbabwe https://commons.ru.ac.za/vital/access/manager/Repository/vital:61087 Thu 02 Mar 2023 14:38:12 SAST ]]> A grounded theory study of the identity and career decisions of artistic creative entrepreneurs https://commons.ru.ac.za/vital/access/manager/Repository/vital:71625 Sun 25 Feb 2024 13:35:22 SAST ]]> Effect of Helicosporidium sp.

Observations of TIDs are made using Global Navigational Satellite Systems (GNSS) total electron content derived data. During quiet conditions, seven and two transhemispheric TIDs were identified over the African-European and American sectors, respectively. The observed TIDs originated from the wintertime hemisphere and propagated into the summertime hemisphere. The horizontal velocity, periods, and horizontal wavelengths of TIDs are in range of cH = 120-274 m/s, 48-80 min and _H = 379-1104 km, respectively. These quiet-time equatorward TIDs have been associated with tertiary gravity waves (GWs) from the dissipation of secondary GWs which are in turn generated from the dissipation of mountain waves (MWs) as a result of excited orographic forcing. The poleward TIDs during geomagnetically quiet conditions over the African and American sectors occur mainly during local daytime. Poleward TIDs were observed mostly in the African-European sector than the American sector. Their horizontal propagation velocities and periods range between 129-280 m/s and 39-70 min over African-European and American sectors. Although the mechanisms responsible for launching quiet-time poleward TIDs have not been established in this study, lower atmospheric processes such as convection systems, sudden stratospheric warming and cold weather fronts may have a role in their generation. During geomagnetic storms in the African sector, almost all poleward TIDs (with the exception of two cases) during the main phase were large-scale with horizontal velocities and periods ranging from 250-503 m/s and 30 min to 2 hours. During recovery phase, poleward TIDs fall under the category of medium scale. In the American sector, the majority of poleward TIDs occurred during the storm's main phase, as opposed to the African-European sector, which experienced a significant number of poleward TIDs during the recovery phase. The periods and horizontal velocities of TIDs range from 45 min-1.5 h and 180-296 m/s during main phase. During the recovery phase, the horizontal velocity and period range from 177-271 m/s and 40-1.5 h, respectively. Overall, it has been shown that statistically, changes in equatorial electrodynamics related to enhanced eastward electric _eld and hence increased equatorial electrojet (vertical E_B drift) correlates highly with the reported poleward TIDs.]]> Sat 06 Apr 2024 13:06:52 SAST ]]> Economically important cephalopods of southern Angola, with a focus on the artisanal jig fishery

This study further estimated the socioeconomic losses due to catch spoilage by C. quadricarinatus which are up to 1500 t per year in the invaded Kafue River Basin, which translates to an annual income loss of US$ 2 million. Information provided in this study is vital for conservation management and to compel policymakers to develop appropriate conservation management tools within regulatory frameworks, which could stop or minimise the spread of crayfish species and protect Africa from further losing aquatic biodiversity.]]> Fri 06 May 2022 11:07:38 SAST ]]> An examination of activism and ‘political listening’ during the year of student protest at the University of Cape Town from 9 March 2015 to 9 March 2016 https://commons.ru.ac.za/vital/access/manager/Repository/vital:61085 Fri 03 Mar 2023 11:43:07 SAST ]]>
