Air transmission lines generally use ACSR type conductors. As the demand for electrical energy increases, effort to increase capacity of line is carried out by optimizing current-carrying existing line, but problem that arises in this optimization voltage and slope conductor. This study aims determine effect current instability on conductor temperature, slope, angle voltage, which then useful c...

PURPOSE To assess the impact of axial length on the age-related peripapillary retinal nerve fiber layer (RNFL) thinning. METHODS This cross-sectional observational comparative case series included 172 eyes from 172 healthy Korean subjects. Peripapillary RNFL thickness was measured using an Optic Disc Cube 200 × 200 scan of spectral domain Cirrus HD OCT and the axial length was measured using ...

This study concerns the interaction of pitch, morphology and vowel length in Tłîchô Yatiì (Dogrib) and Dene Sųłine (Chipewyan), Dene (Athabaskan) tone languages of the Mackenzie River Drainage. Starting from an earlier study we extend it to investigate the realization of tone on long vowels in Tłîchô Yatiì. Our results indicate that slope is a feature of vowel length contrast.

We investigate flow separation in the air flow over transverse sand dunes. CFD simulations of the air flow over differently shaped dunes are performed. The length of the recirculation region after the brink of the dune is found to depend strongly on the shape of the dune. We find that the nondimensionalised separation length depends linearly on the slope of the dune at the brink within a large ...

economic and environmental logging is important for sustainable wood production in the caspian forests, north of iran. predetermination of the skid trail network and directional felling is a usual recommended method to reduce logging impact. the aim of this study was evaluation of directional felling and finding factors effective on felling error. totally 135 trees were selected randomly for di...

Room-temperature continuous-wave operation of large-area (120 microm x 980 microm) GaAs/AlGaAs graded-refractive-index separate-confinement heterostructure lasers on (100) Si substrates has been obtained. Minimum threshold-current densities of 214 A/cm(2) (1900-microm cavity length), maximum slope efficiencies of about 0.8 W/A (600-microm cavity length), and optical power in excess of 270 mW/fa...

Following peripheral nerve injury, moderate daily exercise conducted on a level treadmill results in enhanced axon regeneration and modest improvements in functional recovery. If the exercise is conducted on an upwardly inclined treadmill, even more motor axons regenerate successfully and reinnervate muscle targets. Whether this increased motor axon regeneration also results in greater improvem...
