In this study, nonlinear vibration of axially moving strings in thermal environment is investigated. The vibration haracteristics of the system such as natural frequencies, time domain response and stability states are studied at different temperatures. The velocity of the axial movement is assumed to be constant with minor harmonic variations. It is presumed that the system and the environment...

Savannah River Site has used the metal hydride LaNi4.25Al0.75 (LANA.75) in Tritium Facilities for over two decades. LANA.75 beds store significant quantities of tritium but have a limited service life due to radiolytic decay 3He within matrix. It been shown that isotherm performance tritium-aged sample can be restored by heating under vacuum. Additional investigation is needed ensure there are ...

The thermofield dynamics of the D = 10 heterotic thermal string theory is described in proper reference to the thermal duality symmetry as well as the thermal stability of modular invariance in association with the global phase structure of the D = 10 heterotic thermal string ensemble.
