The present study investigates the hydrodynamic characteristics of diagonal brush upstream fishway at Incirli run-of-river hydropower plant on Iyidere River in Turkey. Three-dimensional velocity measurements were conducted fish pass using a Micro acoustic Doppler velocimeter under real-time operation conditions. arrangement blocks creates favorable conditions (i.e., lateral momentum exchange) t...

b = vortex spacing l = lateral displacement N = Brunt–Väisälä frequency q = root-mean-square turbulence velocity t = time u = axial velocity v = lateral velocity, vertical displacement V = aircraft ground speed w = descent speed, vertical wind velocity x = axial coordinate y = spanwise coordinate z = vertical coordinate = circulation = eddy dissipation rate = potential temperature = standard de...

introduction patellar dislocation is an emergency. vertical patellar dislocation is rare, often seen in adolescents and mostly due to sports injuries or high-velocity trauma. few cases have been reported in the literature. closed or open reduction under general anesthesia is often needed. we report a case of vertical locked patellar dislocation in a 26-year-old male, which was reduced by a simp...

In this paper, we study the effect of MHD turbulence on the dynamics of dust particles in protoplanetary disks. We vary the size of the particles and relate the dust evolution to the turbulent velocity fluctuations. We performed numerical simulations using two Eulerian MHD codes, both based on finite difference techniques: ZEUS– 3D and NIRVANA. These were local shearing box simulations incorpor...

the study of flow in compound channels with vegetated floodplains is essential to assessing the development of the stage-discharge relationship and sediment and pollutant transport. the present study experimentally investigated mean flow and turbulence characteristics in a prismatic compound channel. the experimental program consisted of vegetated and non-vegetated floodplains with different re...

In the present study, we have formulated the G equation concept for large-eddy simulation (LES) of premixed turbulent combustion. The developed model for the subgrid burning velocity is shown to correctly reflect Damköhler’s limits for largeand small-scale turbulence. From the discussion of the regime diagram for turbulent premixed combustion, it is shown that given a particular configuration o...

results first needle placement without imaging resulted in blood return in 1/199 participants and positive epidurography in 179/199 (90%). minimal needle repositioning resulted in a positive epidurogram in the remaining 19 attempts. no intravascular injection patterns were observed. conclusions this compares favorably to published success rates of fluoroscopically-guided technique and was well ...

Idealized nonhydrostatic numerical calculations that resolve both plumes and geostrophic eddies are used to mimic isobaric float observations taken in the Labrador Sea Deep Convection Experiment and study mechanisms of buoyancy transport through mixed layers. The plumes and eddies are generated in a periodic channel, initialized with a vertical profile of temperature, and cooled by surface heat...

We investigated ocean surface and subsurface physical responses to Typhoons Kalmaegi and Sarika in the South China Sea, utilizing synergistic multiple-satellite observations, in situ measurements, and numerical simulations. We found significant typhoon-induced sea surface cooling using satellite sea surface temperature (SST) observations and numerical model simulations. This cooling was mainly ...

AIM The aim of this study was to assess the dynamic activity of the mandible by means of a computerised kinesiograph in Class II patients treated with orthodontic therapy and to compare the results of this group with those of a sample of untreated Class II patients. METHODS Twenty young adolescents who had undergone orthodontic treatment for correction of Class II malocclusion and twenty age ...
