ISBN 952-91-6585-4 (paperback) ISBN 952-10-1476-8 (PDF) The main purpose of the present study was to gain understanding about the rheological (elastic, viscoelastic and viscous) properties of pharmaceutical creams containing sorbitan fatty acid ester surfactants (sorbitan monola...

The paper reviews recent experimental results concerning a wide variety of magnetic nanofluids with high saturation magnetization. Magnetic, rheological and magneto-rheological properties are presented and discussed, especially related to nanostructural processes and colloidal stability in applied magnetic field.

The biogas process has long been a part of our biotechnical solutions for the handling of sewage sludge and waste. However, in many cases the existing process applications need to be optimized to improve the extent of biogas production as a part of the energy supply in a sustainable and viable society. Although the principles are well known, process disturbances and poor substrate utilization i...

The existence of an evolving microstructure in a 2.9 vol% fumed silica paraffin oil and polyisobutylene is demonstrated experimentally via rheological modeling during steady state large amplitude oscillatory shear flow. continuously evolving, rebuilding, breaking down the shown, correlated through rheology experiments, thixo-elastovisco-plastic modeling, small angle light scattering (SALS). All...

In this study, mass, stiffness and damping matrices of the Nosrat jacket; located in Persian Gulf; equipped with Semi Active Tuned Mass Damper (SATMD) system have been derived after modeling the structure in SACS software. Owing to huge number of the degrees of freedom in the model, computation of on-line control of SATMD was time consuming. For this purpose, the size of the model was reduced i...

There are many kinds of deformable objects in our living life. Some of them demonstrate rheological behaviors, such as human tissues, food, and clay. Comparing with elastic or viscoelastic objects, rheological objects have not been studied intensively. Especially, effective methods for parameter identification have not been established until now. In this paper, we summarize two FE dynamic model...

The objective of this study was to investigate the effect of selected biopolymers on the rheological properties of surimi. In our paper, we highlight the functional properties and rheological aspects of some starch mixtures used in surimi. However, the influence of some other ingredients, such as cryoprotectants, mannans, and hydroxylpropylmethylcellulose (HPMC), on the rheological properties o...

We studied the extreme hemodilution to a hematocrit of 11% induced by three plasma expanders: polyethylene glycol (PEG)-conjugated albumin (PEG-Alb), 6% 70-kDa dextran, and 6% 500-kDa dextran. The experimental component of our study relied on microelectrodes and cardiac output to measure both the rheological properties of plasma-expander blood mixtures and nitric oxide (NO) bioavailability in v...

Characterization of rheological behavior of alkali-surfactant-polymer (ASP) solution and oil emulsion is difficult, due to the complex chemical components and various physiochemical reactions with oil during chemical flooding. Through rheological experiments of ASP and crude oil emulsion, this paper presents the studies on influencing factors of rheological behavior, including interfacial tensi...

A simple rheological model has been used to describe foam flow through moving textile assemblies. The validity of this model was tested, and the nature and the relative magnitude of deviations from the model evaluated for several different substrates. Neglecting foam degeneration during transport, the model was found to represent a valuable means of evaluating some rheological and geometrical d...
