introduction: sudden sensorineural hearing loss (ssnhl) is a true emergency that must be diagnosed and treated immediately. the purpose of this study is to compare the efficacy of treatment with intratympanic dexamethasone plus oral prednisolone daily or every other day with that of treatment with oral prednisolone alone. materials and methods: sixty-three patients with ssnhl that had been pres...

The aim of this study was the evaluation of hearing threshold in patients with beta thalasemia major. For this purpose, 178 patients who were under regular chelation therapy with desferrioxamine (DFO) were selected and underwent ear, nose, throat examinations and audiological evaluations. Patients were between 4 to 25 years old and 54.9% were male and 45.1% were female. Three patients were excl...

Traditional connection oriented protocols like TCP NewReno perform poorly over wireless links. The problem lies in their design assumptions based on loss based congestion control. Various modifications to loss based congestion control schemes have so far been proposed to overcome the issue. In addition, the comparatively newer family of delay based congestion control mechanisms like Caia-Hamilt...

introduction: hearing loss is one of the most common occupational diseases. in most workplaces, workers are exposed to noise and solvents simultaneously, so the potential risk of hearing loss due to solvents may be attributed to noise.  in this study we aimed to assess the effect of exposure to mixed aromatic solvents on hearing in the absence of exposure to hazardous noise.   materials and met...

Magnetic fields spontaneously grow at unstable interfaces around hot-spot asymmetries during inertial confinement fusion implosions. Although difficult to measure, theoretical considerations and numerical simulations predict field strengths exceeding 5kT in current national ignition facility experiments. of electrons then reduces the heat loss by >5%. We demonstrate this via magnetic post-proce...

Introduction: Hearing loss is fairly a common disorder which is usually treated with corticosteroids via systemic administration and/or intra-tympanic injection. This study aimed to compare the effectiveness of intra-tympanic injections of dexamethasone with its combination with hyaluronic acid in patients with sudden sensorineural hearing loss.   Materials and Methods: In this clinical trial, ...

Introduction: Neonatal hyperbilirubinemia is one of the most important factors affecting the auditory system and can cause sensorineural hearing loss. This study investigated the relationship between behavioral hearing thresholds in children with a history of jaundice and the maximum level of bilirubin concentration in the blood.   Materials and Methods: This study was performed on 18 children...

seed loss at harvesting time is one of the factors reducing seed yield in at farms. this study was carried out within a research farm in karaj to evaluate and select a proper pinto bean line for mechanized harvesting at two moisture contents during harvesting and their effect on seed yield and yield loss among three lines of pinto bean. the experiment was split-plot based on randomized complete...
