  Background and Objectives:  Currently, Escherichia coli is considered as one of the main causes of bacterial urinary tract infections. The aim of this study was evaluating the frequency of necrotizing factor type 1 (CNF1) and hemolysin (Hly) genes among E. coli strains isolated from hospitalized patients of Rouhani Hospital in Babol city. Materials and Methods: In this descriptive study, a ...

Several inherited polymorphisms are associated with the risk of venous thrombosis, including mutation at codon 506 of the factor V gene and mutation at position 20210 of the prothrombin gene. The aim of this study was to determine the frequency of factor II G20210A and factor V Leiden mutations in Algerian patients with venous thromboembolism disease. In this study, genotyping for factor V Leid...

This paper presents a Bayesian constrained frequency warping technique. The Bayesian approach provides for inclusion of the prior information of the frequency warping parameter and for adjusting the search range in order to obtain the best warping factor dependent on HMMs. We introduce novel frequency warping (FWP) HMMs which are different warped versions of HMMs. Instead of frequency warping o...

dielectric properties of agricultural products is one of the most important physical properties of agricultural and food products and these properties are used heavily in developing as new technology for use in agriculture and related industries. therefore, in this study investigated the changes in the dielectric properties of pazhohesh and ghaem varieties of paddy as a dielectric material four...

Pasteurella multocida possesses various virulence factors, including capsule, lipopolysaccharide, fimbriae, toxins, outer membrane proteins, and adhesions. Adhesins have a crucial role in mediating colonization and invasion of the host. The aim of the present study was to identify the prevalence of adhesion factor genes and resistance/sensitivity patterns among the avian P. multocida isolates f...

A simple semi-phenomenological model, which accurately predicts the dependence of thresholdcurrent for temperature of Resonant-phonon three well quantum cascade laser based on verticaltransitions is offered. We found that, the longitude optical phonon scattering of thermally excitedelectrons is the most important limiting factor for thermal performance of high frequency THz QCLs.In low frequenc...

Considering the challenges in fabrication and electromagnetic characterization of linear accelerator tube, first four major effective parameters in cavity fabrication, including cavity material, dimension agreement, surface roughness and concentricity of cavities have been studied. Then, considering appropriate electromagnetic properties, fabrication results of cavities, techniques for their re...

A Rectangular Dielectric Resonator Antenna (RDRA) is theoretically analyzed using the Conventional Dielectric Waveguide Model (CDWM), numerically simulated using the High Frequency Structure Simulator (HFSS) based on the Finite Element Method (FEM) software package and experimentally investigated with the consideration of the fundamental mode TE 111. Antenna parameters under investigation inclu...
