The analysis of some company"s hose failures indicates that 70% of the failures are caused by leakage between the hose and the fitting. In order to solve the hose fitting leakage problems of the hose assemblies, the experimentation has been carried out and the conclusion is that the fitting"s intension is not strong enough to prevent leakage.

With this method, the nextto-leading order Debye screening mass was evaluated within real time hot QCD. Since the gluon damping rate was included self-consistently on the internal line of the self-energy, the infrared divergences were removed without putting by hand in a nonperturbative magnetic mass as a cutoff, and the results are positive and gauge-independent. In addition, the selfconsistent calculation method of the damping rates of the fast moving particles in a QGP was suggested, the self-consitent equations were derived at finite tempeature without infrared divergences, and the approximation solutions were shown. Meanwhile the relaxation times of the gluons and quarks were estimated as τ〓～0.7fm/c and τ〓～1.5fm/c at energy scales of RHIC and LHC.
