We study the 2-D Helmholtz equation in perturbed stratified media, allowing the existence of guided waves. Our assumptions on the perturbing and source terms are not too restrictive. We prove two results. Firstly, we introduce a Sommerfeld-Rellich radiation condition and prove the uniqueness of the solution for the studied equation. Then, by careful asymptotic estimates, we prove the existence ...

we quantified the distribution, abundance and assemblage structure of macrofauna at 22 stations in gorgan bay, seasonally in 2012-2013. also, depth, temperature, salinity, do, tom and sediment particle size were measured in each station. the highest concentration of tom was measured near the western littoral zone (10.22) while the mouth part and north-eastern area was characterized by the lowes...

People with metabolic syndrome are at high risk for developing cardiovascular disease. The present study aimed to determine the age related metabolic syndrome of hemodialysis patients. The biochemical parameters and demographic information were registered. The prevalence of metabolic syndrome was significantly high in ages 50-59 and 60-69 years in hemodialysis patients when compared with other ...

functionality of marve seed gum (salvia macrosiphon boiss) on rheological properties and staling of baguette bread have been studied. three different concentrations of 0.1 %, 0.5% and 1% (w/w, flour basis) were applied and this hydrocolloid affected the quality of the stored bread to some extent. the effects of marve seed gum on the rheological properties of dough was also investigated instrume...
