The rheological properties of six commercial fluid denture resins were determined by rotational viscometry. Initial viscosity ranged from 67 to 575 centipoise at a rotational speed of 10 revolutions per minute. All resins showed initial non-Newtonian flow behavior and increased viscosity with time.

Abstract In the conditions of high competition on market food products producers have to carry out a search for new kinds raw materials in order diversify assortment produced products. Adding and ingredients different origin composition dairy irrevocably leads change quality parameters. One such parameters is consistence. To control consistence, it necessary check orgonaleptically study structu...

Rotating Shadowband Pyranometers (RSPs) have been deployed to measure global, beam, and diffuse irradiance because they do not require manual adjustment of trackers. However, a RSP requires the use of solar cell based pyranometers which underestimate diffuse irradiance by 20-30% under clear sky conditions. Algorithms were derived to address many of the systematic errors in solar cell based meas...
