The aim of present study was to evaluate the effect of adding whey protein concentrate (WPC) as a fat replacer in the rheological properties of yogurt. Whole yogurt and nonfat yogurt with 0 %, 1.5 %, 3.0 % and 4.5 % of WPC were developed and available. The steady and dynamic shear rheological properties were determined using a HAAKE MARS rheometer at 10 °C with a sensor stainless steel double g...

The rheological behaviour of pulsed electric field (PEF) processed and thermally pasteurised mango nectar (Mangifera indica) was evaluated using controlled stress rheometer. The mango nectar was subjected to pulsed electric field (PEF) as well as thermal processing. The rheological parameter shear stress was measured up to the shear rate of 750 s -1 using co-axial cylinder attachment at wide ra...

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...

Biopolymers have been employed in enhanced oil recovery (EOR) due to their high viscosity and significant effects on waterflooding performance. Sodium alginate (NaAlg) is an excellent biopolymer that extracted primarily from brown algae. It has used the biotechnology industry as a thickening agent, colloidal stabilizer, application. In present study, series of sodium alginate/zirconium oxide na...

A compact-sized falling needle rheometer with quick operation and automatic flow analysis has been developed for viscometry of human blood. The volume of a sample of blood only needs to be 4 mL and the measuring time is within 3 min. Measured flow properties of blood are evaluated as a flow curve showing the relationship between the shear stress and shear rate. Observed flow curves of the human...

the effective factors of forward speed, cylinder rotation, and clearance between a combine’s cylinder and concave on wheat kernel breakage and seed germination were studied in karaj area using a 955 model john dear combine. this study was conducted on three levels of adjustment for each of the variables, 1.2, 1.8 and 2.5 km/hr for forward speed, 800, 900, 1000 rpm for cylinder rotation as well ...

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...

Investigation of the JJPW-G100 air-assisted spraying dust suppression device was performed to obtain reasonable installation angle nozzle in device. First, an equal-scale physical model established, and then effect on atomizing performance investigated in-depth via numerical simulation. Results showed that imposed no significant range device, while initial falling spray field increased with inc...
