BACKGROUND individuals with profound hearing loss may present vibrotactile responses when tested with supra-aural earphones due to the large skull area exposed to vibration in these transducers. AIM to verify the influence of the type of transducer when assessing air conducted pure tone thresholds in individuals with profound sensorineural hearing loss. METHOD 50 individuals, ranging in age...

Frequency discrimination was measured for a wide range of center frequencies (0.25-8 kHz) using three different tasks. In the first (difference limens for frequency, DLFs) subjects were required to indicate which of two successive tone pulses was higher in frequency. In the second (difference limens for change, DLCs), two successive pairs of tone pulses were presented; one pair had the same fre...

Ad hoc networks have been known to be extremely vulnerable to the hidden and exposed terminal problems, which consequently reduce dramatically the network capacity. The total lack of knowledge of the surrounding environment, a characteristic in-wrought with ad-hoc networking, is in most cases the main reason for the degradation of performance in Wireless Mobile Ad hoc Networks (MANETs). To effe...

Objectives: The purpose of this research was to find out the efficacy Castanea crenata Inner Shell (CCIS) distilled herbal medicine on skin by comparing difference effect between only simple water and CCIS application after MTS (microneedle therapy system) treatment.Methods: present author performed once a week total 4 times treatment. treatment time took about 5~10 minutes depth needle adjuste...

Despite longstanding interest in defining what a tone system is and in contrasting tone, pitchand stress-accent systems, there have been surprisingly few attempts to sort out the relevant phonological properties which distinguish “true” tone systems from each other. In this paper, I explore a propertydriven typology of two-height tone systems, based on markedness. Drawing from a current databas...

Many taxa of both marine and freshwater zooplankton perform diel vertical migrations with amplitudes from a few to 100 metres (Hutchinson, 1967). The 'normal' pattern is an evening ascent and a morning descent, though several cases of 'reversed' migrations have been described (Ohman, Frost & Cohen, 1983; Bayly, 1986). Migrating animals spend the day in deep waters but stay near the surface at n...

introduction: the aim of this study was to evaluate the effect of proximal contour of class ii composite restorations placed with straight or contoured matrix band using composite resins with different modulus of elasticity on stress distribution by finite element method. methods: in order to evaluate the stress distribution of class ii composite restorations using finite element method, upper ...
