objective(s):atherosclerosis is chronic inflammatory process triggered by oxidative stress. oxidative stress can increase hydrogen peroxide (h2o2)level, which induce atherosclerosis through the processes such as formation of perivascular adipose tissue (pvat), foam cells, and atherosclerotic plaque. antioxidant is needed to control negative effects of oxidative stress. one source of antioxidant...

A variety of polymers or surfactant mixtures or aeration of a number of liquids could generate mixtures of liquid and foam. Therefore, characterizing the properties of liquid/foam mixtures has important applications in the chemical process industry. The lack of a robust automated method for characterization within limited time and with high accuracy, however, has made this task difficult. In th...

ee front matter & 2005 bmt.2005.04.006 ess: [email protected]. Summary Sensorimotor training was developed by Dr. Vladimir Janda as part of a treatment approach to chronic musculoskeletal pain syndromes. He noted that many of these syndromes exhibited characteristic patterns of muscle imbalance, which were manifested with changes to the central nervous system motor programming. Janda emphasized th...

This paper investigates the parametric study of the empty and foam-filled end-capped tubes under quasi static and dynamic loadings. The numerical crash analysis of the empty and foam-filled tubes was performed using the explicit finite element code ABAQUS- explicit. Satisfactory agreements were generally achieved between the numerical and experimental results. In order to determine the crash be...

This mechanism resembles inflammatory reactions to exogenous factors and the wound healing process (2). Dysfunction of vascular endothelial cells is thought to induce a cascade of pathologic reactions of cell groups mediated by the expression of adhesion molecules, resulting in infiltration of mononuclear cells, foam cell formation, promotion of thrombus formation, and disturbed relaxation of b...

Abstract: Enhanced foam flooding is a chemical flooding technology, which is applied to improve the recovery efficiency of oil and gas. The oil displacement agent of enhanced foam flooding is a foam that the polymer and surfactant solution as liquid. In this paper, three-dimensional mathematical model of unsteady flow is established about enhanced foam system in the porous media, and the numeri...

Liquid foams have important practical applications. To analyze the dependence of foam behavior on material properties, and to improve foam models, foam scientists work with dozens of related simulations obtained by varying these material properties as well as parameters such as foam attributes, properties of objects interacting with foam or shape of foam containers. We present visualization sol...

It is well known that foaming can become a major problem during large-scale recombinant protein bioprocesses; the vigorous stirring and introduction of gases to maintain the required dissolved oxygen (DO) concentration for the organism [1] in addition to the growth medium and protein products themselves [2], can result in the formation and stabilization of foams consisting of gas-filled liquid ...

Foam dynamics is gaining interests within Computational Fluid Dynamics and Computer Graphics. We believe that liquid foam, or froth, is the next evolution in the field of fluid dynamics. Froth is the natural phenomenon of bubbles that arise due to nucleation of gas in liquids. As the physics of foams in two dimensions is better understood this thesis begins the journey of physics-based foam dyn...

This investigation presents the effect of various parameters on foam stability and its rheological properties. The underlying idea of this experiment is generating of drilling foam with uniform bubbles. The main problem of foam using is controlling its stability during field application. The most important parameters which cause Instability in foam are gravity drainage, gas diffusion and bubble...
