introduction: this study aimed to compare the efficacy of mtad, glyde and edta in removing the post-preparation smear layer and debris produced in apical third of curved molar root canals. materials and methods: forty extracted human maxillary first molars with curved mesiobuccal canals (30˚-35˚), similar root lengths and morphologies were divided into 3 experimental groups (n=12) and one contr...

Purpose: Considering the influence of horizontal velocity on many biomechanical characteristics of walking, the purpose of this study was to investigate how inter-lower-limbs local and global asymmetry is influenced by changes in walking speed from slow to fast. Methods: Ground reaction force data and trajectory of attached markers of bilateral lower limbs of 15 right leg-dominant able-bodied ...

OBJECTIVE To determine optimal scissor blade design and surgical approach to facilitate obtaining a long optic nerve segment during enucleation procedures. METHODS Two hundred mock enucleations were performed with the use of a human child skull model and a silicone sphere to simulate an eye. Temporal and nasal approaches with scissor blades with noncurved, mildly curved, or strongly curved bl...

This paper presents a new approach to computing 1=r singularities on curved panels. By using carefully chosen mapping techniques, a curved panel with curved edges is mapped to a at panel with straight edges. Analytical formulas for at panel integrals are then used to give approximate curved panel integration solution. For those curved panels with reasonably large curvatures and smooth edges, th...

the object of this study was evaluation of a walking tractor drawn peanut harvester at different conditions of soil moisture content and forward speed and comparing it with manual harvesting. the evaluation factors for peanut harvester were two levels of soil moisture content and three levels of forward speed. the results revealed that the effect of soil moisture content was only significant on...

the aim of study was to investigate and compare the concentric torque of quadriceps and hamstring muscles and timed-walking test in two groups. thus, one group of healthy subjects and one group of patients with low grade of tibiofemoral osteoarthritis (oa) were selected. concentric torque of quadriceps and hamstring were measured in both groups. besides, pain measurement, timed-walking test, ra...
