The paper industry has a number of processes where the rheology is complex and critical to control for trouble free operation. The rheological properties of pulp suspensions and paper coatings are reviewed here. The flow, rheology and other various phenomena are discussed for pulp suspensions. The particle level models that have been developed for pulp suspensions are compared to experimental r...

There are many conditions where it is useful for anesthetists to have a knowledge of blood rheology.Blood rheology plays an important role in numerous clinical situations.Hemorheologic changes may significantly affect the induction and recovery times with anesthetic agents.But also, hemorheologic factors are directly or indirectly affected by many anesthetic agents or their metabolites.In this ...

Blast furnace slag (BFS) was added into drilling fluid as a mud cake modifier (MCM) for the reuse of BFS. The effects of MCM on drilling fluid rheology and shear strength of cementformation interface (SSCFI) were evaluated. The experimental results showed that the optimized formula of the drilling fluid has 1.0 wt% MCM. The simulation results showed that SSCFI increased significantly with the a...

Rutting is one of the most important distresses in asphalt pavements due to its frequency. Rutting or channeling, could be classified in three types: 1) mechanical deformation (rutting in subgrade or base), 2) plastic flow (unstable asphalt layer), and 3) wheel path consolidation. The plastic flow of bituminous mixture depends on many factors; one of this is the type of asphalt used in the mixt...

in recent years, using sol-gel procedure for the purpose of laboratory and industrial synthesis of nano-structures, and especially silica nano-particles, has been significantly increased. in this research, silica particles were synthesized by sol-gel procedure and their physical and chemical properties were studied by means of scanning electron microscopy (sem), transmission electron microscopy...

There are many kinds of rheology objects in our living life. If such rheology objects are individually and completely modeled, we can flexibly deal with such various objects in a factory by a robotic manipulator controlling six degrees-of-freedom forces and moments and also operate them at a 3-D graphics world in a house by a human via a wonderful haptic devise feeling the forces and moments. I...

Given a role-explicit topic, we firstly determine its kernel-object, then we construct the corresponding modifier graph (Step-1). We perform graph clustering on the induced modifier graph using the algorithm by Noack [4]. Each modifier cluster is viewed as a representation of a particular subtopic. Corresponding to each modifier cluster, we generate the clusters of subtopic strings based on the...

Recent progresses in understanding the behavior of dense granular flows are presented. After presenting a bulk rheology of granular materials, I focus on the new developments to account for non-local effects, and on ongoing research concerning the surface rheology and the evolution of mechanical properties for heterogeneous systems.
