We describe a modeling methodology intended as a preliminary step in the identification of appropriate constitutive frameworks for the time-dependent response of biological tissues. The modeling approach comprises a customizable rheological network of viscous and elastic elements governed by user-defined 1D constitutive relationships. The model parameters are identified by iterative nonlinear o...

The article considers the issue of reducing the influence of clayless mud components on the filtration parameters of the reservoir. In the composition of such solutions, calcium carbonate of various fractions is often added as a weighting and colmatizing additive. It is generally accepted that weighting bridging agents are sufficiently inert substances and their addition does not affect the rhe...

in this study, wasinvestigated the effect of two thickening agents, carboxymethyl cellulose (cmc) and guar on the rheological properties of set fruit yogurt. viscoelastic modulus (g' , g'), apparent viscosity and complex viscosity increased and loss factor decreased by increasing carboxymethyl cellulose and guar content up to 0.2% and 0.06% respectively. however, in the concentrations...

nowadays, nanoscale innovations in the forms of pathogen detection, active packaging, antimicrobial packaging and barrier formation are poised to elevate food packaging to new heights. antimicrobial nanocomposite ldpe films containing zno nanoparticles at different concentrations (e.g. 1%, 3%, 5%  and 3%  nano-zno pulse 10% polyethylene grafted maleic anhydride (pe-g-ma), w/w pure ldpe), were p...

background: the study of rheological properties of blood has special interest since it is a circulating fluid exposed to shear rates during its life time. this work aims to investigate the influence of whole body gamma irradiation on the rheological properties of rat’s blood. the applied shear rate was from 12 to 375 s-1. low shear viscosity (up to 100 s-1) depends mainly on the erythrocytes ag...

This study treats one important aspect of starch-filled rubber compounds which is their rheological behavior. Starch-based SBR1712 masterbatches resulting from various formulations were prepared using a mini two roll mill and an internal mixer (Plastograph Brabender).The content in starch was varied from 0 to 50 phr. The effect of starch content on the rheological behavior was ev...

Background & Aim: Elaeagnus angustifolia L, belongs to Elaeagnaceae family, and, growing in Azarbaijan, Kurdistan, Chaharmahal va Bakhtiari and Esfahan provinces, Iran. Elaeagnus fruit contains a wide range of different food components. Recent researches indicated that there are remedial properties in this plant and, is used as painkiller in patients with rheumatoid arthritis and seizu...

Rheological characteristics of powder injection molding PIM feedstocks play an important role in final properties of manufactured MMCs. In this study, six formulations composed of magnesium and SiC powder (99:1 wt.%) and a specific binder  were prepared to investigate the influence of binder composition, powder to binder ratio, time and temperature on rheological properties of the feedstock. Th...
