The mixing process is often used not only to homogenize the materials, but also bring out better functions by different materials. In involving chemical reactions, it important quickly remove by-products of reaction. this study, a flow field around single rotor rotating in partially filled chamber was numerically simulated using 3D model examine interface renewal characteristics highly viscous ...

An improved version of a pneumatic-tube system built by Amsco, Inc. (Erie, Pa.) and its subsidiary ATC (San Rafael, Calif.) for blood-sample transportation incorporated two innovations: The sample carrier travels at a lower speed than in the previous conventional systems, and itis decelerated gradually on arrival. This tube system was pilot tested for eff iciency by running blood-filled Vacutai...

Direct observation of valence electron density reflecting orbital degrees freedom on partially filled degenerate orbitals.

This investigation is concerned with determination of the dynamic response of a fluid-filled spherical shell subjected to a local radial impulsive load. From the application point of view, such a fluid-shell system is considered to be a simple, but to date, the most improved theoretical model representing the human head when subjected to impulsive external loads. Analysis is based on linear she...

INTRODUCTION The present study compared the ability of the endodontic sealers AH Plus, Pulp Canal Sealer and EndoREZ to fill the root canal system in association with gutta-percha. METHODS Ninety mandibular premolars were accessed, prepared and divided into three groups of 30 teeth each, according to the sealer used to fill the canals: AH Plus, Pulp Canal Sealer and EndoREZ. All the teeth wer...
