Vibration Isolation: Use and Characterization

Vibration Isolation of Precision Objects

The need for vibration isolation of precision and vibrationsensitive objects is increasing continuously. Vibration isolation systems must comply with contradictory specifications, such as requiring reduced stiffness of isolators for better isolation, but higher stiffness for better performance of the object. Recently, expensive active isolation systems have been used to resolve these contradict...

The Isolation and Characterization a Human Diploid Cell Strain and Its Use in Production of Measles Vaccine

Isolation, characterization, and use of stem cells from the CNS.

The nervous system of adult mammals, unlike the rest of the organs in the body, has been considered unique in its apparent inability to replace neurons following injury. However, in certain regions of the brain, neurogenesis occurs postnatally and continues through adulthood. The nature, fate, and longevity of cells undergoing proliferation within the CNS are unknown. These cells are increasing...

A Very Low Temperature Vibration Isolation System

Very low temperature refrigerators are a significant source of low frequency vibrational and acoustic noise, which is a serious challenge to research using high sensitivity mechanical oscillators, or to high resolution scanning tunneling microscopes. We describe the design and operation of a vibration isolation system which is used at very low temperatures. The system consists of four masses su...

Isolation, Screening and Characterization of Hyaluronidase Producing Bacteria

      Hyaluronidase has a panoramic use in biotechnology processes and therapy due to its therapeutic, pathophysiological, physiological and biological importance. Since much of the preparations of hyaluronidases are from animal source (bovine and ovine testicular sources) with limited sources of microbial origin, that prompted the authors to screen and isolate a new promising bacterial strain ...
