Introduction to Air Bearings
Of the more important advantages which are offered by gas lubrication, the low viscosity of gases as compared with liquids can be exploited to special benefit. The extremely low static friction which externally pressurized bearings can offer, finds its uses in torque measuring equipment, dynamic

Melt Flow Rheology Testing for Polyolefins
by using an Arrhenius fit of zero shear viscosity ? 0 verses temperature. Nornally used with the Ellis Flow Model and TTS modeling of master curves of polyolefins. Zero shear viscosity - ?0 can be used for several models, calculations, and with dynamic, stress relaxation, creep compliance, and relaxation

Particle Characterization Technologies
The Dynamic Light Scattering technique measures the time-dependent fluctuations in the intensity of scattered light which occurs because the particles are undergoing random, Brownian motion. Analysis of these intensity fluctuations enables the determination of the distribution of diffusion
