introdouction: the aim of this study was to compare information regarding pharyngeal airway sizes in adolescent subjects with different malocclusion classes obtained from lateral cephalograms and 3–dimensional (3d) cone-beam computed tomography (cbct) scans. materials and methods: in this prospective cross-sectional study, cbct scans and lateral cephalograms of 35 subjects, taken within one wee...

purpose: propofol is one of the most common drugs used in anesthesia induction and the pain during its intravenous injection is one of the most important side effectsthat it has. therefore, many methods and drugs have been examined so far to reduce or eliminate this side effect. in this study a lot the effects of alfentanil, magnesium sulfate and ketamine drugs on reducing the pain during intra...

the aim of this study was to investigate the effect of external intervention factor (types of music) on physical fitness factors in adolescent boys. 30 adolescent boys (9-12 years old, msd height, weight and bmi: 133.82.40 cm, 35.62.97 kg, and 19.91.21 kg/cm2), were selected and performed the tests in three stages (fast music, slow music, control) with counter balance method. in each stage, the...

Mobile ad hoc networks are an emerging wireless technology which differs from other networking technologies in that they are infrastructureless, autonomous, stand-alone networks. Although these characteristics enable simple deployment, ad hoc networks are limited in terms of connectivity as communication is confined to the boundaries of the local network. Due to this constraint, plus the growin...

the aim of the current study was to investigate three volleyball skills in three training conditions of blocked, random and serial to reveal their effects in three phases of acquisition, retention and transfer. 60 amateur male students (mean age = 21.5 years, sd= 1.2) were voluntarily selected and randomly divided into three training groups (blocked, random and serial). a pretest was used to ma...

This paper considers the throughput improvement issue in multi-hop ad hoc networks. We follow the approach that uses both multiple interface equipped nodes and multiple channels. The proposed solution enhances the routing protocol so that it selects routes that use multiple channels and alternate them at each intermediate node in order to reduce the intra-flow interferences. Then it adapts the ...

Sybil identities are a major threat to the dependable operation of wireless ad hoc networks. This paper defines a framework to assess the power and performance of radio resource tests (RRT), a technique that allows the detection of Sybil identities. Several RRTs are analyzed and compared using this framework, including two novel RRTs and an optimization of a RRT previously proposed in the liter...
