‘The White Hordes From the West’: Race and Refuge in Australian Media Commentary About White Rhodesians During Zimbabwe's Decolonisation

Australian Journal of Politics &History, EarlyView.
ABSTRACT This article explores Australian media commentary on white Rhodesians migrating to Australia, focusing on the period of Malcolm Fraser's prime ministership (1975–1983). The main argument is that the Australian media debates about whether to classify white Rhodesians as ‘migrants’ or ‘refugees’ were not merely semantic but reflected a deeper ...

Investigation on high-temperature creep behavior at 300 °C in laser-welded joints of a novel heat-resistant Al alloy of Al–12Ce-0.4Sc

Journal of Materials Research and Technology
The scarcity of studies on the high-temperature creep behavior of laser welds in heat-resistant Al alloys limits their widespread application. This study examines the effects of laser welding and heat treatment on the high-temperature creep performance ...

Enhancing the fastness characteristics of weld‐dyed cotton and recycled nylon 6,6 fabrics via sodium alginate and titanium dioxide

Coloration Technology, EarlyView.
Abstract This study investigates a sustainable dyeing and finishing strategy for recycled nylon 6,6 and organic cotton fabrics dyed with weld. Following meta‐mordant dyeing using alum under Natural Organic Dye Standard (NODS)‐compliant conditions, the fabrics were subjected to functional finishing with titanium dioxide as a multifunctional ...

Navigating challenges in prosthodontic rehabilitation after long‐term delay following fibula free flap reconstruction with a unique overlay removable prosthesis and large vertical dimension increase

Journal of Prosthodontics, EarlyView.
Abstract This case report highlights the experience of one maxillofacial surgical patient who delayed prosthodontic treatment for 7 years as they saved to self‐fund access to a subsidized prosthodontic service. Without the benefit of a restored opposing dentition for a prolonged period of time, maxillary occlusal plane disruption occurred as a ...

Evidence for the continental origin of Pliocene deposits in the central Baja California peninsula, Mexico, and implications for controls on biodiversity

Sedimentology, EarlyView.
ABSTRACT Previous studies have documented genetic divergence within the last few million years between northern and southern populations of terrestrial plants and animals along the Baja California peninsula, with many studies hypothesising that the divergence is due to an ancient seaway that crossed the central peninsula and created a physical barrier ...
