Incorporation of vertically aligned nanorod/nanowire arrays of metal oxide (oxide-NAs) with a polymer can produce efficient hybrid solar cells with an ideal bulk-heterojunction architecture. However, polymer/oxide-NAs solar cells still suffer from a rather low (normally, < 0.4 V) open-circuit voltage (Voc). Here we demonstrate, for the first time, a novel strategy to improve the Voc in polymer/...

Objective: Generated acoustic trauma by suction and drill may cause sensorineural hearing loss after Tympanomastoid surgery. This study was carried out to determine the relationship of sensorineural hearing loss and chronic otitis media surgery at Ahvaz Jundishapur University of Medical Sciences in Iran. Material and Methods: This prospective study included 386 patients of ch...

introduction abnormal neural impulses in the nervous system may lead to various diseases and disabilities. high frequency alternating currents (hfac) has been used to block the propagation of such impulses and improve the symptoms or disabilities. the technique is safe, reversible, and relatively selective, and its reliability, the optimum stimulation parameters, and elimination of the onset re...

footdrop is a relatively common deficit among the neurological disorders, which has different causes with various levels of involvement in neuromuscular system, including central nervous system (brain cortex, spinal cord), fifth lumbar root, peripheral nerves and muscles. peroneal nerve injury at the fibular head has been reported to the most common cause of foot drop, which can be due to infar...

longitudinal heat conduction is an important parameter in the cryogenic field, especially in cryogenic heat exchangers. in the present work, the parasitic effect of tube wall longitudinal heat conduction on temperature measurement has been studied in cryogenic laminar hydrogen flow. the effects of various parameters such as wall cold end temperature, wall thermal conductivity, gas volumetric fl...

carpal tunnel syndrome (cts) is the most well-known and frequent form of median nerve entrapment, and accounts for 90% of all entrapment neuropathies. entrapment neuropathies of the ulnar nerve are relatively common with ulnar neuropathy at the elbow more prevalent than ulnar neuropathy at the wrist. the diagnosis of ulnar neuropathy at the elbow is usually confirmed in a relatively straight – ...

introduction: the aim of the present study was to determine direct effects of no modulation on protective electrophysiological properties of atrioventricular node (av node) in the experimental model of af in rabbit. methods: isolated perfused rabbit av nodal preparations were used in two groups. in the first group (n=7), lname (50μm) was applied. in the second group (n=12), different concentrat...
