This study delves into the interplay between magnetic fields, heat transfer, and fluid behavior within a 3D mini-channel. Exploring the effects of a magnetic field on a hybrid nanofluid (Fe3O4–TiO2) under varying ...
This article discusses the behavior of specific dispersive waves to new (3+1)-dimensional Hirota bilinear
equation (3D-HBE). The 3D-HBE is used as a governing equation for the propagation of waves in fluid
dynamics. The ...
Designers may introduce a system with multiple technologies in series to improve system efficiency.
The configuration can be applied to k out of n systems if each technology contains k out of n factors.
The k out of n ...
Depending on the stress state, mine tailings are generally accepted to be susceptible to static
liquefaction. A common method to assess the in situ stress state of tailings in relation to static
liquefaction susceptibility ...

In South Africa, the Dutch architect P.S. Dijkstra/
Dykstra (1884-1968) is considered an important innovator
in Protestant church design. Yet his work gets
barely a mention in Dutch historiography. His early
twentieth-century ...

The narratives shared on social media during a health crisis such as COVID-19
reflect public perceptions of the crisis. This article provides findings from a study of
the perceptions of South African citizens regarding ...
This study delves into an extensive investigation of the thermophysical properties and heat transfer efficacy of a
hybrid nanofluid incorporating graphene nanoplatelets and γ-Al2O3 nanoparticles dispersed in deionised ...

A recuperated solar-dish Brayton cycle using an off-the-shelf turbocharger as a micro-turbine and a rectangular cavity receiver with integrated thermal storage is considered in this study. Due to the high temperatures that ...
Medical education is vital in producing competent
healthcare professionals and advancing medical
knowledge. The integration of e-learning has emerged
as a transformative approach to enhance medical education by improving ...
Selenium, an essential micronutrient for plants and animals, can cause selenium toxicity as an
oxyanion or at elevated doses. However, the toxic selenite oxyanion, can be converted
into less harmful elemental nano-selenium ...
The role of diffusible hydrogen in the embrittlement of AA2024 after short-term exposure in the standard exfoliation corrosion
(EXCO) test solution (ASTM G34) was investigated. Slow strain rate KR-curves were established ...
This study investigated the use of a limit equilibrium model to simulate the time-dependent scaling of hard rock pillars. In
the manganese bord and pillar mines in South Africa, extensive scaling is observed for pillars ...
The design of pile foundations that are expected to develop significant lateral loading is a complex procedure that requires the development of objective and accurate design formulae that will not be based on semi-empirical ...
New methods are proposed for the verification of the presence of superabsorbent polymers (SAP) in freshly mixed concrete and estimation of SAP quantity. The methods are in general based on flushing concrete with excess ...
