Single crystal X-ray diffraction (SCXRD) analyses demonstrated that each guest compound was retained in the crystals by means of a hydrogen bond with an alcohol moiety of the host compound. Furthermore, preferred guests 6- and 7-ONE produced crystals with greater densities than guests less favoured (5- and 8-ONE). A conformational analysis of the guest geometries in the four complexes with H1 revealed that the low energy guest conformers were present. The host selectivity for 6- and 7-ONE was proposed to be due to the improved molecular packing in the crystals of the complexes containing these two guest compounds, observed from their higher crystal densities. Hirshfeld surface analyses were not useful in explaining the preference of H1 for 6-ONE relative to 7-ONE (these types of analyses were not possible for the 5-ONE and 8-ONE-containing inclusion compounds due to the nature and degree of disorder present in the guest molecules). H1 was also crystallized from γ-butyrolactone (GBL), 2-pyrrolidone (NP), N-methyl-2-pyrrolidone (NMP) and N-ethyl-2-pyrrolidone (NEP), and 1H-NMR spectroscopy revealed that all but GBL were included. The host compound was also presented with these guest solvents in various mixtures, and it was observed that NMP was an extremely favoured guest solvent, followed by NEP and NP, with GBL being consistently disfavoured in every experiment. It was therefore shown that in certain instances, H1 may serve as an alternative tool for separating some of these mixtures through host-guest chemistry strategies. The hydrogen bonding motifs present in each of the successfully formed complexes were extensively investigated through SCXRD analysis, as was the thermal behaviour of these complexes. In the latter instance, the peak temperature of the endotherm (from the DSC trace) representing the guest release was greater for the inclusion compound with favoured NMP (145.5 °C) relative to the complexes with NP (139.8 °C) and NEP (120.5 °C). Host compounds H2 and H3 were revealed to have the ability to include each of pyridine (PYR), 2-methylpyridine (2MP), 3-methylpyridine (3MP) and 4-methylpyridine (4MP). H2 displayed selective behaviour for 3MP and 4MP when presented with mixtures of these guest compounds, whilst H3 preferred PYR. In the latter case, this PYR-containing inclusion compound was also the more stable one (the guest release onset temperature was highest, Ton 66.0 °C). It was demonstrated that H2 has the ability to separate very many binary mixtures of these pyridines on a practical platform, since K (the selectivity coefficient) values were 10 or greater in many instances. However, unfortunately, the more difficult-to-separate mixtures containing 3MP and 4MP cannot be purified or separated by employing H2 and supramolecular chemistry strategies. H3 was also shown to be a likely candidate for binary guest separations in very many of the guest solutions considered here, where K was also 10 or greater, and even infinity in many cases. SCXRD demonstrated that 2MP, 3MP and 4MP were retained in the crystals of their complexes by means of classical hydrogen bonds with the host compound. Satisfyingly, this hydrogen bond between 2MP and H2 (3.0213(18) Å) was significantly longer than that between this host compound and both disorder components of 3MP (2.875(2) and 2.825(9) Å) and that between H2 and 4MP (2.8458(13) Å). This observation explains the affinity of H2 for both 3MP and 4MP, and why 2MP was disfavoured. The results of thermal experiments did not wholly concur with observations from the guest/guest competition experiments. Hirshfeld surface analyses were also conducted but were not entirely conclusive with respect to explaining the host selectivity behaviour. In the case of H3, SCXRD analyses revealed that favoured PYR experienced a classical hydrogen bond with the host compound that was statistically significantly shorter (2.795(2) Å, 165°) than those between the other guest compounds and H3. Additionally, this guest compound was the only one to be involved in a (host)C−H···π(guest) interaction (2.91 Å, 139°) and also a non-classical hydrogen bond with the host compound ((host)C−H···N−C(guest), 2.77 Å (144°)). Finally, Hirshfeld surface analyses showed also that preferred PYR experienced a greater percentage of C···H/H···C (33.1%) and H···N/N···H (11.1%) interactions compared with the complexes with 2MP, 3MP and 4MP. However, it is not clear whether these Hirshfeld observations explain the affinity of H3 for PYR.]]> Thu 20 Jun 2024 15:42:01 SAST ]]> IL-4/ IL-13 directed microglial activation and differentiation in response to LPS-induced neuroinflammation https://vital.seals.ac.za/vital/access/manager/Repository/vital:73554 Thu 20 Jun 2024 14:46:36 SAST ]]> A Protection of Personal Information Act Compliance Framework for the City of Tshwane’s Fresh Produce Market. https://vital.seals.ac.za/vital/access/manager/Repository/vital:69804 Thu 16 Nov 2023 14:23:10 SAST ]]> Uphando ngenxaxheba yemithombo yosasazo ekwakheni nasekuqambeni isigama esitsha: lugxile kunomathotholo, uMhlobo Wenene kwinkqubo iBreakfast eyondlayo ekuseni https://vital.seals.ac.za/vital/access/manager/Repository/vital:73367 Thu 13 Jun 2024 14:59:04 SAST ]]> Factors affecting learning of English as a second language in South African schools https://vital.seals.ac.za/vital/access/manager/Repository/vital:73359 Thu 13 Jun 2024 11:37:00 SAST ]]> The role of hashtag activism in advocating against gender-based violence and promoting perpetrator accountability : subtitle if needed.

However, sightings per unit effort (SPUE) showed that loggerheads were more prevalent than hawksbills in iSimangaliso, likely due to its proximity to this loggerhead rookery. Reefs supported mixed size aggregations with juvenile to adult-sized green turtles (straight carapace lengths, SCLs of 44.9–99.2 cm), whilst hawksbills were mostly juveniles or subadults (SCL range: 37.4–73.4 cm) and loggerheads were mostly adult-sized (SCL range: 66.9–81 cm). Adult sex ratios were slightly female-biased but not significantly different from 1:1. The longest minimum residence periods recorded for individual subadult green and hawksbill turtles (676 and 675 days respectively) and adult-sized loggerheads (621 days) were suggestive of residency. Resident sea turtle activities were typical; they wereobserved foraging, resting, cleaning and interacting year-round, whilst only loggerheads and leatherbacks were observed in breeding behaviour (e.g., patrolling and mating) just after the seasonal arrival of transient individuals. This study thus reveals that the east coast of South Africa hosts regionally important resident and transient sea turtle aggregations with some of the highest SPUE results recorded for the region. This first attempt at monitoring foraging grounds using a variety of techniques and stakeholder groups can serve as the baseline assessment for future work and the foundation for a long-term in-water monitoring programme, allowing for expansion along the entire coastline.]]> Mon 27 May 2024 12:24:52 SAST ]]> A model for measuring and predicting stress for software developers using vital signs and activities https://vital.seals.ac.za/vital/access/manager/Repository/vital:73614 Mon 24 Jun 2024 15:41:42 SAST ]]> Synthesis and applications of hydroxyl-functionalized chemosensors for selective detection of ions in aqueous systems https://vital.seals.ac.za/vital/access/manager/Repository/vital:73613 Mon 24 Jun 2024 14:52:00 SAST ]]> Discipline and dismissal of employees For testing positive for cannabis https://vital.seals.ac.za/vital/access/manager/Repository/vital:73184 Mon 10 Jun 2024 14:28:15 SAST ]]> Defining and regulating de facto and shadow directors: lessons from New Zealand https://vital.seals.ac.za/vital/access/manager/Repository/vital:73182 Mon 10 Jun 2024 13:59:57 SAST ]]> Grade 12 literary writing: Perceptions and practices of educators and learners in an English Home Language classroom https://vital.seals.ac.za/vital/access/manager/Repository/vital:73188 Mon 10 Jun 2024 12:36:15 SAST ]]> A review of the quality of the covid-19 terminology that has been translated into isiXhosa https://vital.seals.ac.za/vital/access/manager/Repository/vital:73185 Mon 10 Jun 2024 11:04:57 SAST ]]> Spatial patterns of human-elephant conflict and elephant space-use in Liwonde National Park, Malawi https://vital.seals.ac.za/vital/access/manager/Repository/vital:72933 Mon 03 Jun 2024 15:51:46 SAST ]]> Characterization of the coastal Aquifer of Gqeberha, South Africa : Developing a conceptual understanding https://vital.seals.ac.za/vital/access/manager/Repository/vital:72932 Mon 03 Jun 2024 15:36:53 SAST ]]> Functional traits and potential physical drivers of offshore benthic epifauna on the west and south coast of South Africa https://vital.seals.ac.za/vital/access/manager/Repository/vital:72931 200 m depth) are challenging to access and remain poorly studied globally. Epifaunal invertebrates comprise a critical trophic level in benthic ecosystems and can serve as indicators of the overall health and functioning. There is limited knowledge of South Africa’s offshore marine environment and benthic ecosystem functioning due to limitations in funding, resources, and the lack of suitable science-based monitoring tools which are vital for sustainable management into the future. The aim of this research was to improve the understanding of epifaunal functioning as well as their potential physical drivers in 13 South African offshore biogeographic ecotypes. The objectives of this study were threefold: 1) to investigate the functional composition of benthic epifauna from 13 biogeographic ecotypes, 2) to quantify the Functional Diversity (FD) associated with epifaunal traits between the different assemblages (i.e. biogeographic ecotypes), and 3) to evaluate the relationship between physical variables and epifaunal functional traits at the biogeographic ecotype level. Biological trait-based approaches were applied to a subset of 80 benthic epifaunal species collected from 909 offshore stations along the west and south coasts of South Africa. Nine biological traits (associated with life history, morphology and behavioural characteristics exhibited by each species) were classified into 39 modalities and weighted with biomass. Community Weighted Means (CWMs) were used to evaluate the benthic epifaunal functional trait composition of the 13 biogeographic ecotypes. Functional composition across the 13 ecotype assemblages on the west and south coast appeared to be dominated by species with similar trait compositions, such as large, long-lived, surface crawling/burrowing/filter-feeding epifauna with medium to no mobility, however, their percentage of contribution to trait expression (CWMs) was higher on the west coast. Functional diversity indices (alpha and beta) showed higher overall FD for west coast ecotypes, with most ecotypes on the continental shelf (except slopes and canyons) being significantly different (p<0.05) from ecotypes on the south coast. The global RLQ (three-table co-inertia) test did not reveal a significant relationship between biomass and physical variables or between biomass and traits (p>0.05). The fourth-corner method was used to test the significance of individual traitenvironment relationships. The fourth-corner results were similar overall to the RLQ analysis, revealing that three physical variables (temperature, depth, and fluorescence) were significantly correlated to two trait modalities belonging to the feeding mode filter-feeders (FM1) and scavengers (FM5). Scavengers were positively correlated with depth and negatively with temperature, while filter-feeders were positively correlated with fluorescence levels. This indicated that the presence of scavenging epifauna increased with a decrease in temperature and an increase in depth. While a positive significant correlation between filter-feeders and fluorescence suggested their potential tolerance or preference for environmental conditions with high levels of fluorescence. This research was the first such study to explore the functional composition and diversity of benthic epifauna and their relationship with potential physical drivers in offshore west and south coast benthic biogeographic ecotypes of South Africa. The application of new tools to quantify the functional diversity of epifauna as indicators of ecosystem health, and their potential physical drivers. This provided a platform on which to advance our understanding of benthic communities and the roles they play in ecosystem functioning under changing environments. Functional trait-based approaches such as those applied in this study can provide us with vital information on the relationship between biodiversity, ecosystem functioning, and physical drivers. Environmental stressors and changing climate patterns threaten to impact marine ecosystems and their functioning. Benthic epifauna are especially sensitive to changes in their environment and these fluctuations could potentially lead to the loss of certain benthic functionality, altering the thresholds these ecosystems have to response to disturbances. This undermines the stability of these ecosystems which can have ripple effects on the health of these ecosystems and their ability to provide the ecosystem services humans dependent on. Having suitable tools to track current and predict future changes will therefore be vital to inform management and conservation strategies for sustainable ocean utilisation.]]> Mon 03 Jun 2024 15:17:03 SAST ]]> Field mapping and geochemistry of lower Jurassic sediments and volcanics of the upper Karoo supergroup near Ha Mosi, Lesotho mountains https://vital.seals.ac.za/vital/access/manager/Repository/vital:72925 Mon 03 Jun 2024 14:40:41 SAST ]]> Integrating state-space modelling and systematic conservation planning to recommend penguin-fishery management zones in Algoa Bay, South Africa https://vital.seals.ac.za/vital/access/manager/Repository/vital:72828 Fri 31 May 2024 14:09:47 SAST ]]> Evaluating antidiabetic properties of selected African medicinal plants in a cell-based model https://vital.seals.ac.za/vital/access/manager/Repository/vital:72827 Fri 31 May 2024 13:48:47 SAST ]]> Investigating the interannual variability of the Benguela coastal upwelling system using a ROMS numerical model from 1993-2014 https://vital.seals.ac.za/vital/access/manager/Repository/vital:72826 Fri 31 May 2024 13:20:48 SAST ]]> Investigating the effect of peptide-functionalized gold nanoparticles on colon cancer cells https://vital.seals.ac.za/vital/access/manager/Repository/vital:72824 Fri 31 May 2024 10:41:16 SAST ]]> Mechanical recyclability and biodegradation of biopolymers, biopolymer blends and biocomposite in natural environmental conditions https://vital.seals.ac.za/vital/access/manager/Repository/vital:72822 Fri 31 May 2024 10:11:48 SAST ]]> Elephant impacts on plant diversity and structure in the Shamwari Private Game Reserve https://vital.seals.ac.za/vital/access/manager/Repository/vital:73597 Fri 21 Jun 2024 15:41:26 SAST ]]> Lion and leopard diet and dispersal in human-dominated landscapes https://vital.seals.ac.za/vital/access/manager/Repository/vital:73596 Fri 21 Jun 2024 14:52:56 SAST ]]> Augmenting the Moore-Penrose generalised Inverse to train neural networks https://vital.seals.ac.za/vital/access/manager/Repository/vital:73595 Fri 21 Jun 2024 14:31:16 SAST ]]> Evaluating elephant, Loxodonta africana, space-use and elephant-linked vegetation change in Liwonde National Park, Malawi https://vital.seals.ac.za/vital/access/manager/Repository/vital:73594 Fri 21 Jun 2024 14:09:53 SAST ]]> The demographic-specific prey preferences of lions and cheetahs, and potential impacts on prey populations https://vital.seals.ac.za/vital/access/manager/Repository/vital:73593 Fri 21 Jun 2024 13:49:49 SAST ]]> The Algoa Bay region groundwater cycle – linking source to coast https://vital.seals.ac.za/vital/access/manager/Repository/vital:73592 Fri 21 Jun 2024 13:14:49 SAST ]]> The Camdeboo-Mountain Zebra mega-reserve as an opportunity to protect viable populations of medium- to large-sized mammals https://vital.seals.ac.za/vital/access/manager/Repository/vital:73590 Fri 21 Jun 2024 12:18:50 SAST ]]> Prevalence of red blood cell alloantibodies in healthy blood donors: A retrospective study https://vital.seals.ac.za/vital/access/manager/Repository/vital:73586 Fri 21 Jun 2024 12:04:30 SAST ]]> Estimation of a generalist meso-carnivore (black-backed jackal) population from a fenced protected area https://vital.seals.ac.za/vital/access/manager/Repository/vital:73589 Fri 21 Jun 2024 12:03:47 SAST ]]> Investigation of the synthesis and characterisation of spiro orthocarbonates and heterocyclic orthocarbonates https://vital.seals.ac.za/vital/access/manager/Repository/vital:73578 Fri 21 Jun 2024 10:26:35 SAST ]]> An in vitro evaluation of the anti-breast cancer activity of Nigella sativa extracts and its bioactive compound in combination with curcumin https://vital.seals.ac.za/vital/access/manager/Repository/vital:73571 Fri 21 Jun 2024 08:33:46 SAST ]]> Implementation of the world health organization surgical safety checklist in the operating room in a private hospital in the Nelson Mandela Bay Municipality https://vital.seals.ac.za/vital/access/manager/Repository/vital:73384 Fri 14 Jun 2024 11:49:48 SAST ]]> An in vitro assessment of pharmacodynamic interactions between selected herbal extracts and anticancer chemotherapeutic agents https://vital.seals.ac.za/vital/access/manager/Repository/vital:73383 200μg/mL). If the herbal extracts had inconclusive IC50 values in the three cell lines subsequent experiments were conducted using 100 μg/mL. The results showed that most of the combinations were antagonistic but, some combinations had synergistic or enhancement effects(1:3 for cisplatin with grape seed or green tea and tamoxifen with grapeseed or green tea, and 3:1 for cisplatin with green tea as well as for tamoxifen with fermented rooibos or green rooibos, and all the 1:1 combinations of 5- fluorouracil with all herbal extracts) with a combination index (CI) < 1. Grape seed and green tea were found to induce apoptosis in the three cell lines. Assays that were conducted to detect apoptosis induction showed positive staining for phosphatidylserine (PS), activated caspase 3, and reactive oxygen species (ROS), mitochondrial membrane depolarization. Analysis of the cell cycle showed two things; 1) that grape seed and green tea were apoptotic in HeLa and MCF7 cells only, and 2) the extracts of green tea and green rooibos, and the combinations of grape seed with all drug compounds arrested the cell in more than one phase of the cell cycle. The combinations of grapeseed and green tea potentially induced apoptosis in various manners but those with both rooibos extracts were unclear in all the cell lines. The results for combinations with grapeseed and green tea are promising and provide a basis for further research as combinations of chemotherapeutic drugs and herbal extracts may be effective therapeutic strategies.]]> Fri 14 Jun 2024 11:23:15 SAST ]]> An Investigation into the challenges of translating mathematical terminologies into Xitsonga https://vital.seals.ac.za/vital/access/manager/Repository/vital:73382 Fri 14 Jun 2024 09:29:47 SAST ]]> Effects of selected natural flavonoids on an optimized insulin resistance induction model on myotubes and hepatocytes in vitro https://vital.seals.ac.za/vital/access/manager/Repository/vital:73085 Fri 07 Jun 2024 14:21:25 SAST ]]> Isadora duncan: An instrumental case study https://vital.seals.ac.za/vital/access/manager/Repository/vital:73084 Fri 07 Jun 2024 14:09:22 SAST ]]> Traditional birth attendants’ perceptions of their role in caring for women during childbirth in the Nyandeni sub-district https://vital.seals.ac.za/vital/access/manager/Repository/vital:73082 Fri 07 Jun 2024 13:38:28 SAST ]]> Honouring the Dead: The Psychological Consequences of the COVID-19 Lockdown Restrictions on Burial Practices and Rituals, amongst AmaXhosa from the Eastern Cape, South Africa https://vital.seals.ac.za/vital/access/manager/Repository/vital:73081 Fri 07 Jun 2024 13:35:40 SAST ]]> Knowledge, attitudes and practices of municipal workers regarding occupational health and safety in the garden route district municipality, Western Cape https://vital.seals.ac.za/vital/access/manager/Repository/vital:73080 Fri 07 Jun 2024 13:19:40 SAST ]]> The intimate relationships of Xhosa men from the East London area: perceptions of the role and responsibilities https://vital.seals.ac.za/vital/access/manager/Repository/vital:73076 Fri 07 Jun 2024 11:57:38 SAST ]]> Exploring the psychological and emotional understanding of Amagqirha within the Eastern Cape province, South Africa https://vital.seals.ac.za/vital/access/manager/Repository/vital:73074 Fri 07 Jun 2024 11:41:56 SAST ]]> Experiences of mothers who are on tuberculosis treatment While caring for their children in Nelson Mandela Bay health district https://vital.seals.ac.za/vital/access/manager/Repository/vital:73071 Fri 07 Jun 2024 11:29:32 SAST ]]> Assessment of knowledge, attitudes, practices and the prevalence of intestinal parasites in Sarah Baartman District, Eastern Cape https://vital.seals.ac.za/vital/access/manager/Repository/vital:73070 0.05). Gender and the responses to who is at risk of getting infected with intestinal parasites had a statistically significant (p<0.05) relationship. Intestinal parasite prevalence from 2012 to 2020 in SBDM was 46.37% which means it was close to half of the sampled population. Males had the highest prevalence as compared to females, with a prevalence of 53.1% xvi in males and 46.9% in females. The highest disease infection was found between ages one and six years. Conclusion: The researcher concluded that the overall awareness, attitudes and practices on intestinal parasites in SBDM were poor. The intestinal parasites present in SBDM were Cytoisospora belli (35.4%) and Giardia lamblia (35.4%), Ascaris lumbricoides (17.7%), Trichuris trichiura (3%), and Taenia species (2%). The study also revealed that the prevalence of intestinal parasites was low from 2012 to 2020. Recommendations were made with an emphasis on education to increase disease prevention and control awareness.]]> Fri 07 Jun 2024 11:22:47 SAST ]]> Psychobiographical study of Daisy De Melker https://vital.seals.ac.za/vital/access/manager/Repository/vital:73067 Fri 07 Jun 2024 11:11:41 SAST ]]> Exploring culturally adapted psychological interventions for mental illness in South Africa: A scoping review https://vital.seals.ac.za/vital/access/manager/Repository/vital:73065 Fri 07 Jun 2024 11:04:04 SAST ]]> Experiences of psychological practitioners when working with Isixhosa speaking minors in the Eastern Cape. https://vital.seals.ac.za/vital/access/manager/Repository/vital:73062 Fri 07 Jun 2024 11:01:30 SAST ]]> The coping experiences of healthcare workers during covid-19 pandemic in the Nelson Mandela Bay health district https://vital.seals.ac.za/vital/access/manager/Repository/vital:73061 Fri 07 Jun 2024 10:47:31 SAST ]]> A study exploring the understanding and interpretations of schizophrenia amongst Zulu Community members, in Durban, Kwa-Zulu Natal Province https://vital.seals.ac.za/vital/access/manager/Repository/vital:73059 Fri 07 Jun 2024 10:40:28 SAST ]]> Knowledge, attitudes and practices regarding social media as a teaching strategy at a public nursing college in Limpopo province https://vital.seals.ac.za/vital/access/manager/Repository/vital:73057 Fri 07 Jun 2024 10:34:08 SAST ]]> A qualitative review on the manner in which psychologists address language barriers in psychological testing with isiXhosa speaking clients. https://vital.seals.ac.za/vital/access/manager/Repository/vital:73055 Fri 07 Jun 2024 10:32:51 SAST ]]> Study on the Isixhosa elder’s perspective on mental illness in buffalo city municipality, Eastern Cape, South Africa https://vital.seals.ac.za/vital/access/manager/Repository/vital:73046 Fri 07 Jun 2024 09:57:51 SAST ]]>
