ObjectiveThe carbon fiber reinforced plastic (CFRP) propeller has such advantages as light weight, high strength, low vibration, low noise, corrosion resistance and fatigue resistance.In order to accurately ascertain the deformation and strain of CFRP propeller blades under hydrodynamic load, this paper proposes an online measurement method for CFR
We constructed an experimental system that can observe bovine sperm motility in three dimensions, simultaneously from the vertical and horizontal directions.The comparison of the experiments conducted using cover glass and square tubing indicates that the effect of the cover glass on the sperm motility is not negligible.Based on this result, we inv
Clay lumps on the aggregate levels is one of the factors that may cause disruption of the binding process andhardening of concrete.Clay lump can not blend with cement so that blocking a merger between the cement withaggregates Stride Arm which eventually led to the compressive strength of concrete will be reduced in the absence ofbinding to each ot
