Background: Succinylcholine is the most anesthetic drug used to muscle relaxation in emergency endotracheal intubation. Unfortunately it can have serious side effects. The perpose of our study was to comparison of Atracurium + Alfentanyl with succycholine. Materials and Methods: In this clinical trial study, one hundred patient randomly designated two group succinylcholine (control group) & At...

Vocal music teaching is an important part of art education in college. For many college students, vocal music learning is very artistic. Learning theories of imitating, behaviors and skills has valuable directive significance in vocal music teaching in college. Social learning theory should be fully taken advantage of in vocal music teaching in college: observational learning should be used to ...

The article deals with the questions of vocal-choral skills, principles vocal exercises ’ selection, methods working at are underlined. is addressed to future music teachers.

Although, grapevines do not have a high chilling requirement, its fulfillment is critical for normal development of the vines. In tropical and subtropical regions such as Farrashband, in the south of Iran, there is no adequate winter chilling to release bud dormancy in grapevines. So it is necessary to consider the effect of chemical dormancy–breaking agents on bud dormancy. In the present rese...

Vowel production in human speech depends both on the vocal tract shape, primarily establishing formant frequencies in the speech spectrum, and the vibration of vocal folds in the larynx, which function as a pressure-controlled valve regulating airflow into the the vocal tract. This research explores the application of the generalized dynamic pressure-control valve model to the synthesis of voic...

Voice production is generally modelled as a two-component dynamical process composed of the vocal folds and vocal tract. Figure 1 shows a diagram of the arrangement of the vocal fold and vocal tract inside the head and neck. The vocal tract is comprised of the pharyngeal, oral and nasal cavities. It is usually modelled as a linear acoustic resonator, and the vocal folds as a nonlinear dynamical...

WE BRIDGE THE GAP BETWEEN TWO ISSUES IN INFANT DEVELOPMENT vocal development and intrinsic motivation. We propose and experimentally test the hypothesis that general mechanisms of intrinsically motivated spontaneous exploration, also called curiosity-driven learning, can self-organize developmental stages during early vocal learning. We introduce a computational model of intrinsically motivated...

OBJECTIVES This study aimed (1) to investigate music theory teachers' professional and extra-professional vocal loading and background noise exposure, (2) to determine the correlation between vocal loading and background noise, and (3) to determine the correlation between vocal loading and self-evaluation data. METHODS Using voice dosimetry, 13 music theory teachers were monitored for one wor...

Hoarseness and dysphonia are often a result of vocal cord polyps which in turn, are linked to vocal trauma. We report the case of vocal polyps in the setting of a 27-year old male with a history only remarkable for Tourette syndrome. We review the literature regarding etiology and pathophysiology of vocal cord lesions and propose vocal tics in Tourette syndrome as an under-recognized etiology. ...
