objectives : bone assessment is essential for diagnosis, treatment planning and prediction of prognosis of periodontal diseases. however, two-dimensional radiographic techniques have multiple limitations, mainly addressed by the introduction of three-dimensional imaging techniques such as cone beam computed tomography (cbct). this study aimed to assess the accuracy of cbct for detection of marg...

Assessment of the peripapillary nerve fiber layer and macular thickness can be determined in ophthalmology using optical coherence tomography (OCT). Decreased nerve fiber layer thickness and macular ganglion cell thickness in optic nerve ischemia have been correlated with visual field loss. OCT allows deep optic nerve head evaluation which helps understand pathophysiology of diseases.  Furtherm...

abstract introduction: noise exposure is the most common cause of tinnitus. a comprehensive assessment of tinnitus and its impact on the quality of life cannot be achieved merely by evaluating the psychoacoustic characteristics of tinnitus. this study aimed at exploring the potential relationship between tinnitus psychoacoustic characteristics and the resulting handicap. materials and methods: ...

Deregulation policy has caused some changes in the concepts of power systems reliability assessment and enhancement. In this paper, generation reliability is considered, and a method for its assessment using intelligent systems is proposed. Also, because of power market and generators’ forced outages stochastic behavior, Monte Carlo Simulation is used for reliability evaluation. Generation r...

carcass yield is important economical parameters for producers and contributors of meat science. in the present study, carcass yield and also the weight losses resulted post mortem until consumption were investigated. the mean values of cold carcass and hot carcass weight were 15.63 and 15.33, the mean value of cooling loss was 1.87% and average value of hot and cold efficiency were 41.44% and ...

  Introduction:   The daf is a large Persian frame drum used as a musical instrument in both popular and classical music which can induce a percussive sound at low frequencies (146–290 Hz) with peaks of up to 130 dBspl. The percussive sounds have a power distribution in the region of saccular sensitivity. In view of the saccular stimulation by sound in humans, we decided to use cervical vestibu...
