In Present study a digital model of hemimaxillectomy was reconstructed by computer and stress distribution of removable partial dentures in tissues, periodontal ligament and bone were thoroughly evaluated. The maximum stress of two different removable partial denture designs which contained buccal and lingual c-shaped clasps respectively were analyzed and compared. It was assumed that a 90 gram...
Objective: This study aims to compare the variables of plantar force, pressure and impulse during walking in men and women with flat feet. Methods: The study population consists of non-athlete students with and without flat feet. Of these, 48 (male and female) were selected as study samples. The peak pressure, force and impulse on the foot were measured during walking by a foot scanner at a sa...
Misfolding of membrane proteins plays an important role in many human diseases such as retinitis pigmentosa, heredity deafness and diabetes insipidus. Single molecule force spectroscopy is a novel technique which measures the force necessary to pull a protein out of a membrane. Such force distance curves contain valuable information on the proteins structure. High-throughput force spectroscopy ...
following the 1994 northridge and 1995 kobe earthquakes, most of modern structures damaged seriously or devastated totally despite the seismic codes of these countries that had been expected to bear advanced criteria for seismic design of structures. after extensive research, the most probable reason of those destructions was attributed to special specifications of near-field earthquakes. in th...
To explain the cause of axial rotation in a scoliotic vertebral column, the influence of the gravitation force on a spine with a C-scoliosis has been investigated by means of a mechanical model. In this model the gravitation force takes hold of the three-dimensionally curved vertebral column eccentrically. From these reflections it appears that the axial rotation in the scoliotic spine can be e...
statement of problem: a general process in implant design is to determine the reason of possible problems and to find the relevant solutions. the success of the implant depends on the control technique of implant biomechanical conditions. objectives: the goal of this study was to evaluate the influence of both abutment and framework materials on the stress of the bone around the implant by usin...

General circulation of Persian Gulf has a cyclonic pattern that affected by tide, wind stress and thermohaline force. Although tidal force is very effective in values of current speed, but thermohaline force is dominant in long time because tidal forcing has a short period and returning nature. Tide and density parameters are important in navigating and shipping, especially when ships approachi...
Magnetic flux measurements of a toroidal magnet revealed a concave-shaped field distribution with a single minimum and a null field along the axis of the torus at the point where the field reversed. The non-linear magnetic field of the toroidal magnet perpendicular to the Ag2O-doped superconducting disc sample with trapped magnetic flux distorted the field line distribution. As a result, the in...
