There is a growing interest in numerically handling of the interface dynamics in multiphase flows with large density and viscosity ratio in several scientific and engineering applications. We present a parallel space-time implementation of a least-squares spectral element method for the incompressible Cahn-Hilliard and Navier-Stokes equations for different densities and viscosities between phas...

We develop a formulation for the single-fluid/two-temperature equations for simulating two-species, compressible, non-equilibrium plasma flows. The divergence-free condition of the magnetic field is enforced via the characteristic decomposition of an extended nine-wave system. The source terms are modified appropriately to improve energy and momentum conservation accuracy. A spectral/hp element...

Background: Helicobacter pylori (HP) infection is one of the most important causes of gastrointestinal diseases such as peptic ulcer. This bacterium has recently been reported to be associated with low serum vitamin B12 level. In this study we investigated the relationship between Helicobacter pylori seropositivity and the serum B12 level in women aging 15-49 years in Khorram Abad . Material...

Background: The major cause of peptic ulcer disease is helicobacter pylori (Hp), and it is also implicated in the pathogenesis of adenocarcinoma of the distal stomach and gastric lymphoma. The incidence of peptic ulcer disease, atrophic gastritis, and gastric adenocarcinoma are more common in people infected of cagA positive strains of Hp. The aim of this study was to determine the prevalence o...

Background: Infectious agents have been suspected as a triggering factor for development of autoimmune thyroid disease (ATD). Some reports from Western countries have suggested association between Helicobacter pylori (HP) infection and ATD. Objective: To investigate the association of ATD with Cag A seropositivity in a population with high rate and early age of onset of HP infection. Methods: I...

Nerolidol (Ner), a major component of many plant essential oils, is known for its various biological properties. However, the low solubility of Ner in water and its susceptibility to degradation limit its application. The aim of our study was to improve the solubility and photostability of Ner through its encapsulation in different cyclodextrins (CDs). The formation constants of cis-, trans-Ner...
