BACKGROUND Enterococcal species have emerged as important pathogens in Iran as well as throughout the world. With the increased use of vancomycin, Vancomycin-Resistant Enterococci (VRE) has become an important nosocomial pathogen. OBJECTIVES The aim of the present study was to determine the incidence and antimicrobial susceptibility pattern of VRE and also to determine the most important gene...

Anthropometric indices that are indicators of nutrition status in children and adults can be affected by racial and geographic factors. The aim of present study was to investigate the relation of skull size and brain volume of Arak University of Medical Sciences students with their age, weight, height and body mass index. The present study was a cross-sectional study on 18-26 years old students...

The purpose of the paper is to construct a polyhedral Markov field in R in analogy with the planar construction of the original Arak (1982) polygonal Markov field. We provide a dynamic construction of the process in terms of evolution of two-dimensional multi-edge systems tracing polyhedral boundaries of the field in three-dimensional timespace. We also give a general algorithm for simulating G...

the essential oils and aromatic water, known as arak in traditional iranian medicine, comes from the aerial part of teucrium persicum boiss., which is grown in fars province located in iran. the samples were collected in summer and the oils and aromatic water were obtained through steam distillation. the chemical composition of the oils was analyzed using gc-ms. an analysis of the chemical prof...

A reversible, ergodic, Markov process taking values in the space of polygonally segmented images is constructed. The stationary distribution of this process can be made to correspond to a Gibbs-type distribution for polygonal random fields introduced by Arak and Surgailis and a few variants thereof, such as those arising in Bayesian analysis of such random fields. Extensions to generalized poly...

background and objectives: hepatitis c virus (hcv) infection is a worldwide concern and it is the major cause of liver disease. several genotypes of the hcv have been reported from different regions of the world. the determination of the hcv genotypes is important for the prediction of response to antiviral treatment and clinical outcomes. so, hcv genotyping in each region is of great importanc...
