Background: Hughes-Stovin Syndrome (HSS) is a rare clinical disorder characterized by deep venous thrombosis and multiple pulmonary and/or bronchial aneurysms. Aneurysms in systemic circulation can also be seen. Case presentation: We report the first case of HSS with aortic aneurysm in a 55-year-old man who initially presented with deep venous thrombosis. The diagnosis of HSS revealing Beh&cce...
abstract amino acids are building blocks of proteins, and play a vital role in living beings existence and their functionality. the interaction of these compounds with metal ions is of great importance to biochemists, and chemists, because their functions can be utilized as a model in understanding enzymes mechanism for transport of metal ions to tissues. among twenty essential amino acids w...
Introduction and purpose: Balance is an index to determine level of elderly independency in their daily activities.The present study, aimed to determine validity and reliability of "dynamic gaiting index (DGI)" in old women. Materials and Methods: This study was conducted among 80 elderly aged more than 60 years old in Dehdasht city. The data were analyzed using Exploratory Facto...
In this paper two linear arrays including a linear 1×4 and a planar 2×2 of microstrip patch and half-mode substrate integrated waveguide (SIW) cavity hybrid antenna are introduced and investigated. These are simply implemented using low cost single layer printed circuit board (PCB) process. The array element consists of a rectangular microstrip patch with appropriate dimensions in the vicinity ...
One of the important issues in many of array systems such as Radar, Sonar, Mobile, and satellite telecommunications is the estimation of DOA of narrowband received signal. CRB is very important in evaluation of parameter estimation. CRB is the lower bound estimation error variance for any unbiased estimation. In this paper, the array antenna with equal distance arrays is extended in two separat...
abstract in recent years, dust storm in western part of iran, especially fars province, caused various problems for people. the aim of this research is the identification of circulation patterns producing dust storms over fars province. for this purpose, firstly the code number 6 of current weather at 12 gmt belongs to 8 synoptic stations during the statistical period of 1992-2003 has been extr...
antenna structures with low side lobe levels are normally the main goal during antenna design. in this paper, a new method for reduction of radiation pattern side lobe level in phased array antenna with uniform and non-uniform weighting is presented. in this method, by changing the array elements weight or adding several elements, such as slc technique, the pattern with low side lobe level can ...
Objectives: The purpose of this study was validation and reliability determination of Persian translated version of Fall Efficacy Scale-International (FES-I). Methods & Materials: Statistical population was Arak,s men and women older adults in 2012-13 and sample was two groups of older adults (over 60 yrs, mean age=68.79±6.41) dwelling in Arak (203 and 120 subjects for exploring and c...
