ABSTRACT: This paper presents scheme for the speed control of electrical drive when the mechanical system shows low damped mechanical resonance. This situation happens when a comparatively long shaft drives the load. In this case the presence of torsion vibrations can cause wear of gear boxes and quality deterioration of the working process and of resulting products. To damp torsion vibrations ...

Multipotent mesenchymal stem cells (MSCs) can undergo self-renewal and give rise to multi-lineages under given differentiation cues. It is frequently desirable to achieve a stable and high level of transgene expression in MSCs in order to elucidate possible molecular mechanisms through which MSC self-renewal and lineage commitment are regulated. Retroviral or lentiviral vector-mediated gene exp...
