Abstract This paper presents an experimental study of abrasive waterjet turning extrusion aluminum alloy (AlMg0,7Si). The aim the is to determine differences two methods from point view machined surface quality and depth penetration, i.e., diameter parts after process. During experiments, traverse speed cutting head rotation turned were changed, other parameters, like pressure water, mass flow ...

abstract background and aim: considering the widespread development of implants in dental treatment plans, linear measurements on panoramic radiography are of especial importance. in the present study we investigated the effect of head misalignment up to 15° around vertical and horizontal axes on the magnification rate of digital panoramic radiography in each part of upper and lower jaws. mater...

This study presents a method for fabrication of ultrafine polymeric nanofibers as well as nano/micro particles utilizing centrifugal and electrostatic forces simultaneously. To reduce the diameter and variety of nanofibers produced from solid state polymerized PA66, a unique electrocentrifuge spinning device was utilized with a rotating nozzle and collector, while the fabrication process (spinn...

The article deals with the examination of the relationships between density, structure parameters and strength of human trabecular bone. The tests were carried out on the samples taken from osteoporotic and coxarthrotic human femoral heads. The samples cylindrical in shape had the diameters of 10 mm and the height of 8.5 mm. During the tests with microCT scanner the parameters of a sample struc...

Abstract In order to evaluate the effects of drought stress and defoliation on sunflower, a study was conducted under controlled conditions. Treatments were a combination of three levels of drought ((100, 60 and 30 percent of Field Capacity (FC)) and three levels of defoliation (control, removal of either 4 or 6 leaves from lower part of the plant) laid out, in a Completely Randomized Design w...

background: dystocia is one of the important causes of maternal morbidity and mortality in low-income countries. this study wasaimed to determine the diagnostic accuracy of maternal anthropometric measurements as predictors for dystocia in nulliparous women. materials and methods: this prospective cohort study was conducted on 447 nulliparous women who referred to omolbaninhospital. several mat...
