data envelopment analysis (dea) is a technique used to compare efficiency in various sectors such as hospitals, chain stores, and dealerships. it represents a set of linear programming techniques and uses deter-ministic data (inputs and outputs), in stable conditions. the dea technique cannot be used when there is data with indeterministic nature, or when there is an environment with dynamic co...

in light of provided progresses in ultrasound measurements of lateral abdominal muscles, an important role for these muscles, particularly transverse abdominis (tra) muscle in stability of the spine has been suggested. some authors have found significant correlations between body mass index (bmi) and thickness of these muscles. the aim of this study was to examine possible association between d...

Background & Aims: The orbital cavity is an important anatomic structure in the face. It is in close connection with the skull, paranasal sinuses, and the nose. Precise knowledge of the orbital cavity dimensions can be helpful in the diagnosis and treatment of diseases associated with the orbital cavity. Due to the lack of adequate research on orbital size in Iran and the city of Kerman, the ai...

This study was conducted to evaluate and compare the levels of aflatoxin M1 in raw and pasteurized milk samples during different seasons by Enzyme- Linked Immuno Sorbent Assay in Sanandaj, Iran. In 257 (94.49%) out of 272 milk samples the presence of aflatoxin M1 was detected in concentrations ranging between 0.007 and 115.930 ng/l. AFM1 level in 12 (4.4%) of positive samples were higher than t...

background: indoor radon gas (222rn) has been recognized as one of the health hazards for human. air radon comes mainly from basement soil and construction materials. saghand region with rich uranium mines lies 180 km from yazd, so the indoor radon concentration can be high. yazd, with population of about 457000, is the biggest city near saghand, thus, indoor gamma background radiation of yazd ...

introduction quantitative susceptibility mapping (qsm) is a new contrast mechanism in magnetic resonance imaging (mri). the images produced by the qsm enable researchers and clinicians to easily localize specific structures of the brain, such as deep brain nuclei. these nuclei are targets in many clinical applications and therefore their easy localization is a must. in this study, we aimed to i...

acoustic experimental data of irib (islamic republic of iran broadcasting) server room was taken to measure the acoustic noise characteristics of frequency and sound pressure level (spl). the purposes of this paper are measuring the noise pollution and its evaluation through the regulations. the measurements were taken in two stages. the first one was taken at 10 points by sound investigator 22...

abstract background: the measurement of hand grip strength has several clinical applications to evaluate chronic hand disability, response to treatment, and work capacity after hand injury. methods: we measured hand grip strength of 41 adults and compared their maximum strength with radiographic indices. results: there was a significant relationship between hand grip strength and carpal height,...
