Magnetorheological (MR) uids represent a class of smart materials whose rheological properties change in response to the application of a magnetic eld. These uids typically consist of small (m) magnetizable particles dispersed in a non-magnetic carrier uid that generally contains additives such as surfactants and anti-wear agents 1]. Due to such additives , there is an outer non-magnetic layer ...

In this paper we consider nite element methods for a degenerate elliptic-parabolic partial diierential system which describes the ow of two incompressible, immiscible uids in porous media. Local mesh reenement techniques for solving this degenerate system are discussed. 1. TWO-PHASE FLOW EQUATIONS In this paper we consider nite element methods for the ow of two incompressible, immiscible uids i...

In this article, the ow of uids in porous media is studied as a free or moving boundary problem by the mixed method. In particular, a new weak formulation for the problem of seepage of uids through a porous media is discussed and analyzed mathematically and numerically. The new formulation is in a mixed form and is suitable for the use of mixed nite element methods in the numerical approximatio...

1 Objective Aid the Air Force modeling community by developing a \mid-level" approach to simulating the behavior of complex uids, such as viscous incompressible uids, hydrothermal uids, inviscid uids, multiphase uids, and superruids. Traditional approaches to complex uid simulation include \low-level" molecular dynamics or \high-level" partial diierential equation approximation schemes. MD suue...

A great variety of volatile-rich material is fed into subduction zones, including all sorts of marine sediment, altered oceanic crust and some serpentinized mantle lithosphere1. Subduction delivers these materials to depth, but their subsequent history depends on how pressure and temperature increase together. In the cool shallow subduction zone, !uids are liberated at subsolidus temperatures, ...

Mourre's commutator method is used together with Besov spaces, in this paper, to settle the question of uniqueness of solutions to the scattering problem for the acoustic wave propagation in perturbed stratiied uids in R n with n 2: The uniqueness of solutions is established by introducing a radiation condition in the framework of Besov spaces, and is then used to prove resolvent estimates in t...

 Background: Ferula persica has been used in traditional medicine for treatment of high blood pressure. In this study acute and chronic effect of aqueous F. persica extract on BP of hypertensive rats and its possible mechanism of action have been investigated. Methods: Eighty two male Wistar rats were divided into 12 experimental groups. Hypertension was induced by Goldblatt method in ...

In this paper, we present a diagrammatic technique to represent the information exchange during the interaction between the user and the application called User Interaction Diagram (UID). UIDs have proven to be a valuable technique to gather requirements since they describe the exchange of information in a high level of abstraction, without considering specific user interface aspects and design...
