Abstract Using 2D particle-in-cell plasma simulations, we study electron acceleration by temperature anisotropy instabilities, assuming conditions typical of above-the-loop-top sources in solar flares. We focus on the long-term effect T e ,? > ,? instabilities driving growth during entire simulation time through imposing a shearing or compressing velocity ( and are temperatures perpendicular...
Background: Noise-induced hearing loss is a sensorineural hearing loss, which is associated with exposure to high levels of sound. Since train drivers exposed to high noise levels and the use of hearing protection devices is relatively difficult and they also need to hear the radio communications, this study examines the hearing status of train drivers of Yazd Railway Company. Methods: This i...
iintroduction: repetitive transcranial magnetic stimulation (rtms) modulates the excitability of cortical neural networks. the effect of rtms on excitability of cortical networks depends on its frequency. according to the previous reports, a distinction is made between low (<1hz) and high frequencies of rtms. low frequencies of rtms inhibit seizure but high frequencies increase it. in the curre...
There is no evidence that previous studies, available to Iran’s inflation literature, have used spectral methodology to analyze a possible relationship between inflation and its main determinants within a specific period. Accordingly, the present study investigates the effects of money growth, real output growth, output gap and interest rate changes on inflation at low and high frequencies...
abstract ion selective electrodes (ises) are electrochemical sensors that respond selectivity to the activity of ionic species. an ion-selective electrode is an electrochemical device that uses a thin selective membrane or film as the recognition element, and is an electrochemical half-cell equivalent to other half-cells of the zeroth (inert metal in a redox electrolyte). in common methods o...
INTRODUCTION In this study we tested the hypothesis that tirasemtiv, a selective fast skeletal muscle troponin activator that sensitizes the sarcomere to calcium, could amplify the response of muscle to neuromuscular input in humans. METHODS Healthy men received tirasemtiv and placebo in a randomized, double-blind, 4-period, crossover design. The deep fibular nerve was stimulated transcutaneo...
The hearing loss that appears with ageing or presbyacusis should not lead to withdrawal from communication an elderly person. The disorder should be recognised early. The first warning sign is difficulty for understanding in a noisy environment. When an individual indicates this problem, measurements of auditory functions should first be made and regular followed-up should be scheduled or thera...
