radiology and imaging data of patient is the main and the most important data of the patient. not only it shows disease of patient, but also it is included of the body geometry such as 2d and 3d. gathering and saving of radiology images and data for different patients can be useful for future statistic studies. many questions like, how to, why, in which and etc can be answered by statistic meth...

background and aim: motor vehicle accidents are common cause of mortality, morbidity and disability. human factors are principle cause for frequency of motor vehicle accident. in most studies, 52-40% lower limb injuries are trauma from a motorcycle accident. these accidents cause high financial cost and harm for society. materials and methods: in this study, patients with lower limb injuries re...

investigating the frequency of traumatic nasal bone fracture in patients with and without old septal deviation and possible deviation. prospective study of 105 patients with nose trauma conducted and cases were divided into two groups: a study group 35 patients with nasal fracture and a control group of 70 patients without nasal fracture. diagnosis of septal condition was made by anterior rhino...

Background and Aim: Cleaning and shaping is one of the important steps in endodontic treatment, which has an important role in root canal treatment outcome. This study evaluated the rate of file fracture and file deformation in Neolix rotary system and K-files in shaping of the mesiobuccal canal of maxillary first molars with moderate curvature.    Materials and Methods: In this ex vivo exp...

The propagation of Stoneley waves in a fluid-filled borehole with a vertical fracture is investigated both theoretically and experimentally. The borehole propagation excites fluid motion in the fracture and the resulting fluid flow at the fracture opening perturbs the fluid-solid interface boundary condition at the borehole wall. By developing a boundary condition perturbation technique for the...

objective: to evaluate sensorimotor nerve damage in patients with maxillofacial trauma referring to taleghani hospital, tehran, iran methods: this cross-sectional study was conducted during a 2-year period from 2014 to 2012 in taleghani hospital of tehran. we included a total number of 495 patients with maxillofacial trauma referring to our center during the study period. the demographic inform...

Laboratory experiments were performed on cubic samples of Austin Chalk to investigate the effect of fabric-induced anisotropy on the interpretation of fracture specific stiffness. The experimental results found that the fabric-induced layering complicates the interpretation of fracture specific stiffness. Seismic measurements from a sample with small layers (i.e., spacing and thickness) show th...
