Corrosion of metals and metallic alloys is due to their thermodynamic instability in relation to their oxidation form.Corrosion tests performed in this work simulate the exposure conditions in different environments of yellow tombac Trimmers (brass containing 10-20% Zn).The aim of corrosion test in humid heat is to determine the behaviour of surfac
Because of the randomness of wind speed and the nonlinearity of the dynamic equation of variable pitch control, it is difficult to establish an accurate dynamic equation of variable pitch of floating fan.In view of this situation, Trimmers this paper takes the 5 MW floating wind turbine of the NREL (National Renewable Energy Laboratory) as the rese
On a frequency, depending on their size, small celestial bodies enter into the Earth atmosphere and collide with our planet.On a daily Photo Frame basis, the size is likely to be about 20 cm, while for monthly events the largest it may be is about 1 m.The last significant witnessed event occurred in 1908 in the Siberian area of the Tunguska.The for
Direct laser writing is an effective technique for fabrication of complex Coolers 3D polymer networks using ultrashort laser pulses but to date it is difficult to obtain a time-resolved microscopic picture of the printing process in operando.Here, the use molecular dynamics simulation to model direct laser writing and investigate the effect of writ
Cyclin D1 regulates G1 progression.Its transcriptional regulation is well understood.However, the mechanism underlying cyclin D1 ubiquitination and its subsequent degradation is not yet clear.We report that cyclin D1 undergoes increased degradation in the cytoplasm during S phase in a variety of cancer cells.This is mediated by phosphorylation Dish
