Modal Analysis of 27 mm Piezo Electric Plate for Small
This work presents progress towards the development of a small-scale, purely sonar-based navigation device for a robotic fish (~394 mm long). Aperture overloading of small (5 mm diameter) ultrasonic transmitters does not allow them to be used effectively inside water. A test on a 27 mm diameter buzzer piezo plate shows promising performance under water at frequencies from 4.5 kHz to 80
Development of testing procedure for ceramic disc filters
Jul 01, 2011· The main principle of the test procedure applied to conventional rotary vacuum disc filters is that a small filter element, a leaf, is used for simulating a section of the full-scale filter disc. This means that the first requirement for successful tests is that the properties and structure of the leaf are exactly identical to the full-scale discs.

Occupational Exposure to Asbestos Occupational Safety
Aug 10, 1994· In 1986, in its list of activities considered "small-scale, short-term," OSHA listed some which are neither small-scale or short-term, but were regarded as lower risk, such as roofing work. To cure this confusion, OSHA proposed, in 1990 to limit the "small-scale, short duration" exemption to a subset of renovation, removal and demolition
