tan films with different n2 partial pressure were deposited on 304 stainless steel using the magnetron sputtering method. the effect of gas pressure on the mechanical property, morphology and phase structure of the films is investigated by x-ray diffraction (xrd), atomic force microscopy (afm), microhardness testing, friction coefficient measurements, and wear mechanism study. the xrd results c...

the aim of this study was to determine the combination effect of latanoprost and pilocarpine on theintraocular pressure and pupil size in normal rabbits. in this study, 18 rabbits were randomized to threegroups of 6 animals each. the right eyes of rabbits in group 1 were treated topically with latanoprost, ingroup 2 with pilocarpine and in group 3 with latanoprost and pilocarpine. the left eyes...

background: creating a socket with proper fit is an important factor to ensure the comfort and control of prosthetic devices. several techniques are commonly used to cast transtibial stumps but their effect on stump shape deformation is not well understood. this study compares the dimensions, circumferences and volumes of the positive casts and also the socket comfort between two casting method...

a periodic increase in blood pressure (bp) occurs during apneic episodes in patients with obstructive sleep apnea (osa). several factors including hypoxemia and an increase in heart rate (hr) were reported to be responsible for this increased bp. to examine the contribution of these two factors in increasing bp, 35 healthy male subjects (mean age±sd= 23.64±3.80) were studied in three experiment...

the fluid flow and heat transfer in a three-dimensional microchannel filled with al2o3- water nanofluid is numerically investigated. the hybrid scheme is used to discretize the convection terms and simpler algorithm is adopted to couple the velocity and pressure field in the momentum equations. the thermal and flow fields were analyzed using different volume fractions of nanoparticles and diffe...

objective: for many years in herbal medicine the antihypertensive and lowering blood lipid properties of achillea wilhelmsii (a. wilhelmsii) have been suggested. in the present study the impacts of the plant extract on rabbit’s blood pressure and heart rate have been investigated. materials and methods: twelve nwz rabbits weighed 2-3 kg were randomly divided into two groups of 6 rabbits. the te...

background: normal standard references of blood pressure (bp) for children and adolescents have been suggested to be constructed based on anthropometric indices. accordingly, we aimed to develop first bp reference percentiles by weight and age for iranian children aged 3-18 years old. materials and methods: a total of 16,246 children and adolescents aged 3-18 years were included from 3 cross-se...

results mean and standard deviation of self confidence, body image and social pressure were lower than the normal community. statistical analyses showed a significant difference between genders only for mean self-confidence (p ≤ 0.05). background in iran, rhinoplasty has seemingly become the most favorite cosmetic surgery in the recent years, yet, there are limited reports about its psychosocia...

background: at the present time, massage has become a popular therapy employed in complementary medicine. there is evidence showing that back massage might have many positive psychological effects, possibly due to having many autonomic nervous system afferent inputs. one of the frequent positions during massage is prone position. however, there has been limited research investigating the effect...

chemical vapor deposition (cvd) is one of the most popular methods for producing carbon nanotubes (cnts). the growth rate of cnts based on cvd technique is investigated by using a numerical model based on finite volume method. inlet gas mixture, including xylene as carbon source and mixture of argon and hydrogen as carrier gas enters into a horizontal cvd reactor at atmospheric pressure. in thi...
