Objective(s): Oxidative stress has been established as a key cause of alcohol-induced hepatotoxicity. Licochalcone B, an extract of licorice root, has shown antioxidative properties. This study was to investigate the effects and mechanisms of licochalcone B in ethanol-induced hepatic injury in an in vitro study. Materials and Methods: An in vitro model of Ethanol-induced cytotoxicity in BRL cel...

Vibration of nuclear power plant components can cause fretting wear and fatigue that eventually lead to component failure. Flexible, high-aspect-ratio under flow, such as the wire-wrapped cylindrical fuel elements in a liquid metal-cooled fast reactor core, are particularly susceptible vibration due their low natural frequencies. The flow-induced vibrations experienced by tend be random amplitu...

This paper reports the results of experimentally removing ammonia from synthetically prepared ammonia solution using a micro scale mixing loop air stripper. Effects of various operational parameters (such as: pH, air flow rate, wastewater flow rate and initial ammonia concentration) were evaluated. By increasing the pH from 10 to 12.25 the amount of KLa increased from 0.26 to 0.73 hr-1. A consi...

Flow induced vibrations are an important concern in the design of nuclear reactors. One of the possible designs of the 4th generation nuclear reactors is a lead-cooled fast reactor of which MYYRHA is a prototype. The combination of high liquid density, flow velocity, low pitch-todiameter ratio and the absence of grid spacers makes this design prone to flow induced vibrations. Although most vibr...
