1. CaracterizaÃÃo de ligantes asfÃlticos modificados com borracha de pneu e aditivo / Characterization of asphalt binders modified with rubber and tire additives
In Brazil, the annual production of waste tires is in the order of 40 million units, with an estimated tire disposal of at least 25 million units per year. According to statistics of the National Association of Tire Industry, 100 million of useless tires are spread around the country in landfills, vacant land, rivers and lakes, causing enormous environment d

2. Study of hydrodynamics and heat transference from liquid whole egg through plate with three formats chevron / Estudo da hidrodinamica e transferencia de calor do ovo integral liquido atraves de placas com tres formatos chevron
At this work are showed the heat transference and hydrodynamics of liquid egg flow between ducts with corrugated walls, simulating plate heat exchangers. The contour conditions admitted was the constant temperature in the walls during the fluid heating. The whole egg rheology was experimentally determinated in a extend temperature range (289 ? 335K). The egg

3. Rheology and transition shapes of elastic liposomes in nanopores membranes / Reologia e transição de formas de lipossomas elasticos em membranas de nanoporos
In this work, liposomes prepared with comercial egg lecithin and octaoxyethylenelaurate-ester (PEG-8L) were characterized and studied in respect to PEG-8L incorporation, shape transitions, elasticity and rheology in nanopores membranes. Conventional liposomes (without PEG-8L) were used as control. The concentrated caffeine, extracted of guarana seeds, was in

4. The role of the rheological properties of non-newtonian fluids in controlling dispersive mixing in a batch electrophoretic cell with Joule heating
The problem of the effect of Joule heating generation on the hydrodynamic profile and the solute transport found in electrophoretic devices is addressed in this article. The research is focused on the following two problems: The first one is centered around the effect of Joule heating on the hydrodynamic velocity profile and it is referred to as "the carrier

5. Studies on the rheology and oxygen mass transfer in the clavulanic acid production by Streptomyces clavuligerus
In the present work rheological characteristics and volumetric oxygen transfer coefficient (kLa) were investigated during batch cultivations of Streptomyces clavuligerus NRRL 3585 for production of clavulanic acid. The experimental rheological data could be adequately described in terms of the power law model and logistic equation. Significant changes in the

6. Role of erythrocytes in leukocyte-endothelial interactions: mathematical model and experimental validation.
The binding of circulating cells to the vascular wall is a central process in inflammation, metastasis, and therapeutic cell delivery. Previous in vitro studies have identified the adhesion molecules on various circulating cells and the endothelium that govern the process under static conditions. Other studies have attempted to simulate in vivo conditions by
