the aim of this study was to compare the effect of an aerobic exercise program with two different volumes on some risk factors of cardiovascular diseases in mentally retarded girls. 24 mentally retarded girls were randomly assigned to three groups: 1) aerobic exercise, 3 sessions per week for 45 minutes, 2) aerobic exercise, 4 sessions per week for 40 minutes, and 3) control. the experimental g...
This study examines how taper design affects corrosion and fretting at the head trunnion surface. All hip prostheses retrieved between 1999 and 2013 with 28mm/+0 heads were selected, resulting in 44 cobalt-chrome-on-polyethylene implants, representing six taper designs. Mean implantation time: 8.9±3.7years. The femoral head tapers were scored for fretting and corrosion using the Goldberg scale ...
This study was made to clarify the retentive force of a denture retainer, i.e., a cone-type stud and sleeve attachment. In order to measure the wearing effect, an engaging and disengaging cycle test of 1,000 times was performed. The effects of taper angle (cone angle), sleeve height and thrusting force at engaging stud and sleeve on retentive force were also analyzed. 1. The cycle test had litt...
introduction: the aim of the present study was to compare hand stainless steel k-files and nickel-titanium profile 0.04 taper 29 series rotary instruments for their efficiency, procedural errors and time consumed in preparation of root canal system. materials and methods: a total of 46 maxillary and mandibular first premolars extracted for orthodontic purposes were collected (two contralateral ...
introduction: the aim of this study was to evaluate the effects of training duration and case difficulty on the radiographic quality of root canal fillings performed by dental students in saudi arabia. methods and materials: a longitudinal cohort study was conducted at king saud university. root canal treatments performed by 55 dental students from 2012-2014 were included in the study. each stu...
We present experimental studies of the gain length and saturation power level from 1.5 nm to 1.5 Å at the Linac Coherent Light Source (LCLS). By disrupting the FEL process with an orbit kick, we are able to measure the X-ray intensity as a function of undulator length. This kick method is cross-checked with the method of removing undulator sections. We also study the FEL-induced electron energy...
Vertebrate photoreceptors are commonly distinguished based on the shape of their outer segments: those of cones taper, whereas the ones from rods do not. The functional advantages of cone taper, a common occurrence in vertebrate retinas, remain elusive. In this study, we investigate this topic using theoretical analyses aimed at revealing structure-function relationships in photoreceptors. Geom...
This study examined the acute training responses of heart rate variability (HRV) and salivary biomarkers (immunoglobulin A and alpha-amylase) following a standardised training bout in Paralympic swimmers. Changes in HRV, sIgA and sAA were documented Monday morning, Monday afternoon and Tuesday morning over a 14-week monitoring period leading into international competition. Magnitude based infer...
The aim of this study was to evaluate the ability of three obturation methods to seal root canals prepared using 0.06 taper rotary instruments. Forty-five extracted human single-rooted teeth were instrumented with 0.06 taper Profile nickel-titanium rotary files and randomly divided into three experimental groups containing 15 teeth each. The first group was obturated using the System B techniqu...
Background: The increasing of age, inflammatory factors¸ and metabolic syndrome are the effective reasons in the reduction of brain volume. The aim of this research was to investigate the effect of twelve week aerobic exercise with moderate intensity on IL1β, IL-6, and brain volume in 50-65 years old women with metabolic syndrome. Materials and Methods: 24 women wi...
