Pengujian performa Electric Ducted Fan (EDF)
ARMATUR : Artikel Teknik Mesin & Manufaktur, 2022 EDF is an electric propulsion consists of a duct, fan, and electric motor with the motor power source coming from a battery which creates compression air for thrust. The design and configuration of an EDF is not complicated as a jet engine, but it could generate high thrust for highspeed flying like highspeed UAV needs. The preliminary design of an EDF

Attacking the public health crisis of hepatocellular carcinoma at its roots
Hepatology, EarlyView., 2022 Abstract As the third most common cause of cancer‐related death worldwide with significant mortality rates in the United States, hepatocellular carcinoma has strong association with cirrhosis and chronic hepatitis B virus (HBV) with a growing at‐risk population from the rise in chronic liver disease from alcohol use and nonalcoholic fatty liver disease.

Health disparities in chronic liver disease
Hepatology, EarlyView., 2022 Abstract The syndemic of hazardous alcohol consumption, opioid use, and obesity has led to important changes in liver disease epidemiology that have exacerbated health disparities. Health disparities occur when plausibly avoidable health differences are experienced by socially disadvantaged populations.

Aeroacoustic Simulations of an Axial Fan with Modelled Turbulent Inflow Conditions
International Journal of Turbomachinery, Propulsion and Power, 2023 In applications, the acoustics of fans can differ significantly from the measurements of the standalone fan. This is due to disturbed inflow conditions, for example, caused by a heat exchanger upstream of an axial fan.
