3D forensic crime scene reconstruction involving immersive technology: A systematic literature review
(Institute of Electrical and Electronics Engineers, 2022)Recreation of 3D crime scenes is critical for law enforcement in the investigation of serious crimes for criminal justice responses. This work presents a premier systematic literature review (SLR) that offers a structured, ... -
Towards the development of a novel bipolar-based battery in aqueous electrolyte: Evaluation of the electrochemical properties of NiCu based hydroxide electrodes fabricated on Ni–mesh and graphite composite current collectors
(Journal of Energy Storage, 2022)The use of bipolar electrodes in rechargeable batteries can improve specific power, simplify cell design, and reduce manufacturing costs. However, bipolar-based batteries still suffer from many drawbacks. Therefore, ... -
4-(Dimethylamino)pyridinium chlorosulfonate: A new ionic liquid exhibiting chlorosulfonic acid action as monoprotic Brönsted acid and no sulfonating reagent
(Journal of Molecular Liquids, 2021)Many papers considered chlorosulfonic acid as a sulfonating and sulfating agent, whereas our previous work and a few reports showed it acts as a monoprotic Brönsted acid. Therefore, in the present work, we decided to respond ... -
Male age and progressive sperm motility are critical factors affecting embryological and clinical outcomes in oocyte donor ICSI cycles
(Reproductive Sciences, 2021)This retrospective cohort study aimed to explore whether paternal age and semen quality parameters affect the embryological and clinical outcomes of ICSI with oocyte donation. A total of 339 oocyte donation (OD)-ICSI cycles ... -
Resilience and sustainability of the water sector during the Covid-19 pandemic
(MDPI, 2022)The COVID-19 pandemic brought unprecedented socio-economic changes, ushering in a “new (ab)normal” way of living and human interaction. The water sector was not spared from the effects of the pandemic, a period in which ... -
Pansharpened landsat 8 thermal-infrared data for improved land surface temperature characterization in a heterogeneous urban landscape
(Elsevier, 2022)Challenges associated with adolescents are prevalent in South African societies. During the adolescence stage, children may become involved in deviant behaviour. Although a significant number of studies have focused on the ... -
Evaluating the impact of land use and land cover change on unprotected wetland ecosystems in the arid-tropical areas of South Africa using the Landsat dataset and support vector machine
(Taylor and Francis Group, 2022)The study explored the impact of Land Use and Land Cover (LULC) change dynamics in relation to the condition and status of an unprotected wetland located in the arid-tropical parts of the Limpopo Province, South Africa. ... -
Assessment of concentration levels of contaminants in groundwater of the Soutpansberg region, Limpopo Province, South Africa
(MDPI, 2022)Groundwater contributions towards improved food security and human health depend on the level of contaminants in groundwater resources. Many people in rural areas use groundwater for drinking purposes without treatment ... -
Helichrysum genus and compound activities in the management of diabetes mellitus
(MDPI, 2022)The global management of diabetes mellitus (DM) involves the administration of recommended anti-diabetic drugs in addition to a non-sedentary lifestyle upon diagnosis. Despite the success recorded from these synthetic ... -
Characterisation of hydro-geochemical processes influencing groundwater quality in rural areas: A case study of Soutpansberg region, Limpopo Province, South Africa
(MDPI, 2022)Groundwater is often the main or only source of fresh water supply in arid to semi-arid rural areas owing to decreasing rainfall patterns, reduced availability of surface water and socioeconomic activities. It is important ... -
Feasibility assessment of the application of groundwater remediation techniques in rural areas: A case study of rural areas in the Soutpansberg region, Limpopo Province, South Africa
(MDPI, 2022)Groundwater contribution towards human health and livelihood depends on the contaminants level in groundwater. Many people in rural communities are being exposed to waterborne diseases resulting from drinking untreated ... -
A quantification mechanism for assessing adherence to information security governance guidelines
(Emerald, 2022)Boards of Directors and other organisational leaders make decisions about the information security governance systems to implement in their companies. The increasing number of cyber-breaches targeting businesses makes ... -
Exomol line lists – xliv. Infrared and ultraviolet line list for silicon monoxide (28si16o)
(Oxford University Press, 2022)A new silicon monoxide ( 28Si16O) line list covering infrared, visible, and ultraviolet regions called SiOUVenIR is presented. This line list extends the infrared EBJT ExoMol line list by including vibronic transitions ... -
First observation of the coexistence of multiple chiral doublet bands and pseudospin doublet bands in the A ≈ 80 mass region
(Elsevier, 2022)Two nearly degenerate positive-parity bands with the π g2 9/2 ⊗ ν g−1 9/2 configuration and three nearly degenerate negative-parity bands with the π g9/2(p3/2, f5/2) ⊗ ν g−1 9/2 configuration have been identified in ... -
Ultralarge-scale approximations and galaxy clustering: Debiasing constraints on cosmological parameters
(Oxford University Press, 2022)Upcoming galaxy surveys will allow us to probe the growth of the cosmic large-scale structure with improved sensitivity compared to current missions, and will also map larger areas of the sky. This means that in addition ... -
