The mechanical properties of a homologue series of side-chain mesomorphic netM.orks were studied with a piezo-rheometer over frequencies ranging from 10~~

A new concrete rheometer is introduced including its innovation, actual design, working rules,calibration, and reliability. modified design of Tattersall two-point device created. Some ofcomponents are purchased from local foreign markets, while other components themanufacturing process locally fabricated. The matching viscosity method determining the mixerviscometer constants demonstrated foll...

Water damage is one of the main forms early highway asphalt pavement, which seriously affects service performance pavement. To address problem water addition anti-stripping agents in an effective technical means. further analyze influence on performance, Qingchuan rock asphalt, acylamine agent, fatty amine + agent and were selected to modify base asphalt. The rheological properties modified tes...

This study aims to investigate the preferred viscosity of irreversible hydrocolloid used in the preliminary impression for edentulism. Thirteen modalities of irreversible hydrocolloid were prepared by changing the W/P ratio. Discrimination test for the preferred viscosity was performed on 11 prosthodontists (10.4+/-5.3 years of prosthetic experience). The parameter of discrimination test (P%) w...

chitosan is a polysaccharide derived from chitin by n-deacetilation, which has the property of gel formation. the objective was to develop a chocolate milk beverage using modified (hydrogel) chitosan as a thickening agent, and to make a sensory and rheological evaluation of this beverage. in the sensory evaluation an acceptability and comparative test with 50 local consumers was carried out, wi...

A simple but robust kinetic mathematical model to predict the mechanical/thermal behaviour of NR and highcis polybutadiene rubber blends is presented. The benchmark blend is a 70% NR with 30% high-cis polybutadiene blend vulcanized in presence of sulphur at 1 phr and single accelerants TBSS or DPG at concentrations equal to 1-0 and 0-1 respectively. Experimental rheometer curves are at disposal...

Texture of fatty liver, as a multiparameter attribute, has been examined more and more during the last decade. The instrumental texture analysers used are developed on the analogy of penetration tests to imitate the action of human jaws. In this study a Physica UDS200 rheometer was used, fitted with a MP31 top plate and a Peltier bottom plate. Rotational rheometer measurements using plate-plate...
