background: ventriculoatrial (va) conduction has an important role in the initiation and maintenance of some arrhythmias. the aim of this study was to evaluate whether clinical and electrophysiological parameters of atrioventricular (av) conduction can predict va conduction. methods: detailed demographic, electrocardiographic, and echocardiographic data were recorded in 54 consecutive patients ...

introduction: vestibular evoked myogenic potential (vemp) has recently been broadly studied in vestibular disorders. as it is evoked by loud sound stimulation, even mild conductive hearing loss may affect vemp results. bone-conducted (bc) stimulus is an alternative stimulation for evoking this response. this study aims to assess the characteristics of bc-vemp in different groups of patients.   ...

determination of f-wave latency is a simple and valuable method in evaluating proximal part of peripheral nerves. the aim of this study was to determine the mean minimal peroneal f wave (f min) in healthy individuals. a total of 282 individuals were studied. the mean age was 45.6 years. the f min (± sd) for 564 peroneal nerves was 47.09 ± 4.51 ms. the f min for the age group of 20-45 and height...

The non-Fourier effect in heat conduction is important in strong thermal environments and thermal shock problems. Generally, commercial FE codes are not available for analysis of non-Fourier heat conduction. In this study, a meshless formulation is presented for the analysis of the non-Fourier heat conduction in the materials. The formulation is based on the symmetric local weak form of the sec...

In this paper, the combination of conduction with radiation into a semitransparent medium which includes absorption, emission and scattering has been investigated. In order to Study the conduction in medium, the Non-Fourier heat conduction has been applied. In this model there is a time delay between heat flux and temperature gradient. Also, in contrast with Fourier heat conduction, the speed o...

background: carpal tunnel syndrome is the most common neuropathy in the general population. nerve conduction studies are among the standard methods for diagnosing carpal tunnel syndrome. electromyography is painful and unpleasant, and if nerve conduction studies can be used to diagnose axonal injury in carpal tunnel syndrome, electromyography might be replaced. objectives: this study aimed to e...

in this work we solve the set of hydrodynamical equations for accretion disks in the spherical coordinates (r,θ,ϕ) to obtain the explicit structure along θ direction. we study a two-dimensional advective accretion disc in the presence of thermal conduction. we find self-similar solutions for an axisymmetric, rotating, steady, viscous-resistive disk. we show that the global structure of an advec...

results one hundred and eighty-eight anesthesiologists (84.3 %) agreed to participate in the study. while all participants had made their first attempts in neuraxial blocks (nbs) when they were residents, this ratio was detected as 96.8% for pbs. all participants learned neuraxial and pbs on patients in the operating theater. education proficiency ratios for spinal, epidural and pbs were 98.1 %...
