Of these, UV-C irradiation was more efficient than the rest in achieving full and permanent (i.e. without bacteria regeneration) inactivation after short periods of contact time.
However, although the chemical crosslinks are fewer, they are indeed very important for making the large fraction of physical crosslinks permanent, i.e. that they do not slip under load.
The material's resistance to shock loading was evaluated using such parameters as surface and internal visual damage, the magnitude of permanent (i.e., after-shock, residual) deflection, and post-mortem compressive strength.
For our experiment this translates into the time needed for a permanent (i.e. not just temperature induced) viscosity reduction.
They're probably waiting for the damage to be permanent i.e. when enough folks place orders and the company will have to quickly backtrack and fold under indignant customers.
When (R_{0} > 1), there exists a unique rumor-prevailing (E_ ), and the rumor is permanent, i.e., the infected individuals will persist and we have convergence to a uniquely prevailing equilibrium level.
