in this paper, finite element elastic contact analysis of a functionally graded (fg) hollow brake disk in contact with pad, subjected to rotation, contact pressure and frictional heat is presented. the material properties vary through the thickness according to a power-law characterised by a grading index, n. the material property is purely steel at the core part and gradually moves and approac...

background: no comprehensive study has been conducted on risk factors of sexual dysfunction in women with diabetes mellitus. objectives: the aim of this study was to consider all possible influencing variables including hormonal, physical and, psychological status, socioeconomic status, and dietary intake to get more accurate and reliable results. patients and methods: sexual function was asses...

conclusions obtained results demonstrate significant differences between intraneural and perineural injection pressures in the median, ulnar, and radial nerves. intraneural injection pressures show low specificity but high sensitivity suggesting that pressure monitoring might be a valuable tool in improving the safety and efficacy of peripheral nerve blockade in regional anesthesia. peripheral ...

Introduction: World Health Organization (WHO) introduced hypertension as an epidemic in developing countries. However, hypertension is adequately controlled in only 12.5% of patients.  The aim of this study was to evaluate the relationship between Ramadan fasting and mean arterial pressure (MAP). Methods: This clinical, observational study was carried out at Medical O.P.D of Jinnah Medical Coll...

the examination of available vapor pressure data in the case of the methane, ethane, propane and butane halogenated refrigerants, allowed recommendations of standard equations for this property. in this study, three new models include a general correlation; a substance-dependent correlation and an artificial neural network (ann) approach have been developed to estimate the saturated vapor press...

visit-to-visit variability (vvv) in blood pressure (bp) creates challenges to hypertension control and was independent associated with increased all-cause mortality in hypertensive patients. the major goal of the present study was to investigate the association of vvv in systolic (s)bp with progression of carotid atherosclerosis and en-dothelial dysfunction in on-treated hypertensive patients.o...

objective: the aim of this study is to measure the effect of different condensation pressure on the microleakage of mineral trioxide aggregate (mta).  methods: this study was an invitro study. a total of 55 single rooted straight-canal human extracted sound teeth free of cracks or calcification were selected. teeth were sectioned from cej region at 3 mm above the root apex. remaining specimens ...

background: to study the effect of oral garlic on arterial oxygen pressure in children with hepatopulmonary syndrome. materials and methods: garlic powder in a capsule form was given to 15 children with hepatopulmonary syndrome (confirmed by contrast echocardiography) at the dosage of 1 g/1.73 m2 per day. patients were evaluated clinically and by arterial blood gas every four weeks. results: th...

introduction: cataract is an opacified lens and senile cataract is a common disorder. it is desirable to reduce intraocular pressure (iop) in order to minimize intra and post operative difficulties and complications. many researches have studied the effects of muscle relaxants on iop. comparison effect of atracurium and pancuronium on iop has been evaluated in one study with a small sample size...
