background and objective: the medicinal plant origanum vulgare. subsp. vulgare in the lamiaceae family has been widely used by iranian people for the treatment of respiratory, gastrointestinal and neurologic disorders. the present study was carried out to evaluate possible anxiolytic effects of aqueous extract of o. vulgare leaves and the flowering branches in rats.materials and methods: anxiol...

PURPOSE Tension band wiring is commonly used for fixation of simple transverse fractures. The popular configuration is parallel Kirschner wires (K-wires) and a stainless steel wire loop placed in a vertically oriented figure-of-8. METHODS We used a wooden model of a patella with a midway transverse fracture and compared four different types of fixation. The first construct had a vertical figu...

the production of shear flow profile in a wind tunnel test-section with the aid of in-plain horizontal wire-grids is explained. the design procedure with experimental results are given. it is concluded that the deepest shear, produced by this procedure, cannot have a slope of more than 1.777. it is shown that the stagnation streamlines in a shear flow will be displaced due to the existence of s...

An experimental investigation was carried out to determine heat transfer coefficients for natural convection from a heated horizontal wire. The heating is provided by electrical current, and the temperature of the wire is determined from the measurement of its resistance. The experiments are performed in three different convective environments: air, water, and oil. Prandtl number ranged between...

PURPOSE Research has shown that the orientation of the exiting wire from a scleral search coil (nasal in the original coil, inferior in the modified coil) influences the pattern of torsion associated with blinks, presumably due to the upper eyelid touching the wire. The present study was conducted to investigate whether coil wire orientation also influences the pattern of torsion during fixatio...

The wire scanners are used for a measurement of the very small beam size and the emittance in Accelerator Test Facility (ATF). They are installed in the extraction beam line of ATF damping ring. The extracted beam emittance are εx=1.3x10 m.rad, εy=1.7x10 m.rad with 2x10 electrons/bunch intensity and 1.3GeV energy[1]. The wire scanners scan the beam by a tungsten wire with beam repetition 0.78Hz...

OBJECTIVE The aim of this study was to compare the friction between three bracket models: conventional stainless steel (Ovation, Dentsply GAC), self-ligating ceramic (In-Ovation, Denstply GAC) and self-ligating stainless steel brackets (In-Ovation R, Dentsply GAC). METHODS Five brackets were used for each model. They were bonded to an aluminum prototype that allowed the simulation of four mis...

Some new passive and active methods for reducing the effects of seismic disturbances on suspended masses are described, with special reference to gravitational radiation detectors in which differential horizontal motions of two or more suspended test masses are monitored. In these methods it is important to be able to determine horizontal seismic accelerations independent of tilts of the ground...
