On the Prospects for African Philosophy in Australia

Australian Journal of Social Issues, EarlyView.
ABSTRACT This paper grapples with the situation of people of African descent in Australia by working through the constitution of the body of academic philosophy in the country. It contends with the parochialism of the Australian philosophical community and the prospects for the cultivation of greater pluralism. Taking African philosophy as one possible

Optimizing sampling frequency of surface and downhole measurements for efficient stick-slip vibration detection

Petroleum
Drilling vibrations significantly impact drilling operations with high costs due to early downhole equipment failure and loss of productive time. Stick-slip vibrations, a severe form of torsional vibrations, is known to be present up to 50% of total ...

Physicochemical and Mechanical Characterization of Commercial Collagen‐Based Wound Dressings

Advanced NanoBiomed Research, EarlyView.
Commercial collagen‐based wound dressings are systematically compared to reveal how porous architecture governs hydration‐driven swelling and mechanical adaptation. Distinct structure–function relationships are identified, showing that wet‐state elasticity and conformability emerge from material composition and processing rather than manufacturer ...

Mechanical plaque removal in step‐1 of care

Periodontology 2000, EarlyView., 2023
Abstract Maintaining a regular oral hygiene routine is essential for taking care of our mouths, ensuring healthy teeth, and achieving fresh breath. Patient education on oral hygiene is an important component of their overall treatment. Firstly, patients should be informed about the direct connection between bacteria in dental plaque and oral diseases ...

Two‐Dimensional Flow and Thermal Energy Transfer in Non‐Newtonian Casson–Carreau Ternary Hybrid Nanofluids Over Stationary and Moving Wedge Surfaces With Radiation and Magnetic Field Effects

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Efficient thermal management in advanced industrial systems requires improved heat transfer performance, particularly under non‐Newtonian fluid behavior and complex surface geometries. This study investigates the two‐dimensional flow and heat transfer characteristics of ternary hybrid nanofluids over both stationary and moving wedge surfaces ...
