background south pars special economic energy zone is the world's second largest gas reservoir that was established two decades ago. high incidence of social harms is observed in this region due to various problems such as drug addiction which is of high prevalence. conclusions it is necessary to implement simultaneous national interventions as soon as possible to improve the economic, social, ...

background: the purpose of this study is to fabricate inexpensive in-house low cost homogeneous and heterogeneous human equivalent thorax phantom and assess the dose accuracy of the treatment planning systems (tps) calculated values for different lung treatment dosimetery. it is compared with thermoluminescent dosimeter (tld) measurement. materials and methods: homogeneous and heterogeneous tho...

a finite volume-lattice boltzmann algorithm is applied to study skin friction behaviour in different channel flows. for this purpose, cell centred scheme is adapted to discretize the boltzmann equation and consistent boundary conditions are also addressed, which resulted in a wider domain of stability. a simulation of flow in a two dimensional channels with different geometries are carried out....

we describe a case of leishmaniasis in a 55-year-old male who presented with weakness, fever and anemia. the patient was born and lived all his life in talaghan, a non-endemic region of kala-azar and there was no history of travel to endemic reigon for leishmania. in primary diagnosis, the patient suspect has been myelofibrosis and then lymphoma and underwent chemotherapy . his general conditio...

purpose : to offer a semi-automatic algorithm to determine the area of angiographic hyperfluorescence methods : the proposed algorithm included wavelet filter, histogram equalization and modified otsu thresholding. hyperfluorescent area of 30 angiographic images obtained from patients with leaking choroidal neovascularization (cnv) and diabetic retinopathy were evaluated and the results were co...

objective(s): helicobacter pylori, a human specific gastric pathogen is a causative agent of chronic active gastritis. the vacuolating cytotoxin (vaca) is an effective virulence factor involved in gastric injury. the aim of this study was to construct a recombinant protein containing antigenic region of vaca gene and determine its antigenicity.   materials and methods: the antigenic region of v...

introduction: the persian squirrel (sciurus anomalus) is considered the only well-known species of the family sciuridae in the middle east. since some people keep this squirrel as a domestic pet, their attendance at veterinary clinics is increasing. so far, no study has been conducted on the arterial supply of the pelvic cavity and limb in the squirrel. hence, this research was performed to fil...

One of the important issues in data envelopment analysis (DEA) is sensitivity analysis. Heretofore the existent studies have considered the data modification of inputs and outputs in one or multiple DMUs. In this paper the number of DMUs is increased and a stability region is obtained in  by applying defining hyperplanes in which if the added DMU (only one DMU) is in this region then all of the...
