Aluminum alloys have excellent properties such as low density and high strength-to-weight ratio.However, the negative Heavy Duty Walkers standard electrode potential of aluminum leads to a more active chemical property and is prone to corrode; as a result, the poor corrosion resistance extremely limits the widespread application of aluminum.Therefo
Estimation of the Motion Performance of a Light Buoy Adopting Ecofriendly and Lightweight Materials in Waves
In this study, the methods and results of numerical simulations to estimate the motion performance of a newly developed lightweight Table Linens light buoy in waves and to check the effect of conceptually developed appendages on that performance were introduced.The results from a potential-based motion analysis with viscous damping coefficients obt
Bactericidal activity of 5 kinds of disinfectant on Vibrio cholera isolated from drinking water in Baqupa city.
Background: Cholera is an infectious, acute, diarrheal disease caused by bacterium Vibrio cholerae.About 3-5 million cases and over 100,000 deaths occur each year around the world.Vibrio cholera found in water or food sources that have been contaminated by feces from a person infected with cholera.Cholera is most likely to be found and spread in pl
An improved inlet for precisely measuring the atmospheric Ar/N2 ratio
The Pool Toys atmospheric Ar/N2 ratio is expected to be useful as a tracer of air-sea heat exchange, but this application has been hindered in part due to sampling artifacts.Here we show that the variability in δ(Ar/N2) due to thermal fractionation at the inlet can be on the order of 40-80 per meg, and we introduce the Chinese Ginseng use of
