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...

In recent decades, the use of self-consolidating concrete has become widespread. Hence, recognizing the various properties of self-consolidating concrete are essential. In this study, several mixture designs have been tested and final mixture design of crushed tile aggregates which were replaced by 0%, 25 %, 50%, and 100% volume percentage of natural aggregates were conducted. To evaluate fresh...

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...

The instrument for determination the texture with air puff’s Foodtexture Puff Device (FPD) is a new device that yields contactless, fast, easy and non-destructive rheological measurements of food products. The instrument applies a controlled air pulse to the surface of a food product, while a laser distance sensor measures the deformation. This approach can be considered as an alternative metho...

To mimic in vivo vibration of vocal fold cells, we studied the controllability and range of frequency, acceleration, duration, and shear stress in a new bioreactor attachment. The custom multiwell disc appliance fits into a commercially built rheometer, together termed a torsional rheometer bioreactor (TRB). Previous attachments to the TRB were capable of 50–100 Hz vibrations at relatively high...
