Computational fluid dynamics modeling and analysis of cyclone separator design for engine air filtration

Abstract Engines operating in dusty mining environments are vulnerable to intake fouling and combustion degradation from high particulate loading. This study evaluates a cyclone separator as a passive pre-filtration device for heavy-duty generator air intakes, using field-derived...

Genetic characterizations and seroprevalence of hepatitis B virus among non-human primates and human caretakers in Indonesia

Hepatitis B virus (HBV) is a major human pathogen also detected in non-human primates (NHPs), yet its cross-species and zoonotic transmission potential remains poorly defined. We screened 237 NHPs across 10 species together with 65 human caretakers from four major Indonesian isla...
