Microbial contamination in pharmaceutical industry presents annoying problem to those working in the field & costs companies millions of dollars from recalls, product spoilage, rework or rejection and biofilm formation. Monitoring tools & trending of bioburden in the area of drug manufacturing is critical step to evaluate degree of microbial control in pharmaceutical manufacturing. In order to achieve good microbial control disinfectant validation program must be established. This book provides simple guide to determine antimicrobial efficacy of two selected commonly used disinfectants with...

The main object of this thesis is the mathematical study of the dynamic behavior of the rotor-AMB described by non-linear differential equations with quadratic and cubic nonlinearities and time-varying stiffness. The non-linear rotor-AMB system with time-varying stiffness subjected to multi-external excitations or multi-parametric excitations or single-external and single- tuned excitation or multi-external and multi- tuned excitations and multi- external, -parametric and -tuned excitations (as a general case) are studied. The method of multiple time scales is applied to solve the non-linear...
