In this study, an unsteady aerodynamic simulation is performed to realize the influences of platform surge motion on the aerodynamic performance of a high capacity offshore floating wind turbine. A dynamic model with pitch angle control system is utilized to propose a more realistic model of wind turbine and also achieve the rated condition of the rotor. The transient effect of platform surge m...

To assess the effects of mill operating parameters such as speed, ball filling, slurry concentration and filling on grinding process size distribution product, it was endeavored to build a pilot model with smaller than mill. For this aim, 1 m × 0.5 implemented. There are 15 lifters 50 mm height face angle 30˚. In present work, combination balls (40% 60 diameter, 40% 40 diameter 20% 25 diameter)...

The motility characteristics of natural assemblages of coastal marine bacteria were examined. Initially, less than 10% of the bacteria were motile. A single addition of tryptic soy broth caused an increase in the motile fraction of cells but only after 7 to 12 h. Motility peaked at 15 to 30 h, when more than 80% of cells were motile. These results support the proposal that energy limits motilit...

Objective. Incomplete spinal cord injury (SCI) patients have the potential to regain some ambulatory function, and optimal reorganization of remaining circuits can contribute to this recovery. We hypothesized that repetitive transcranial magnetic stimulation (rTMS) may promote active recovery of motor function during gait rehabilitation. Methods. A total of 17 incomplete SCI patients were rando...

With the enormous growth in data amount day by day storage demands have been imposed crucial requirements for data center, where data access plays essential role in estimation of data storage systems effectiveness. For that, there were a lot of efforts have been done to speed up searching in huge storage systems. Deduplication, one of the latest technologies in storage systems world, is founded...

Moisture contents of Hom Nil rice flour for fixed extrusion conditions, 120 and 80°C of die and transition zone temperature of barrel, respectively and 250 rpm screw speed, were varied at 13, 15 and 17%. Physicochemical and sensory properties of the product were evaluated. The 15% moisture content of rice flour caused the optimum properties of extrudate. The effects of diezone barrel temperatur...

BACKGROUND Muscle co-activation plays an important role in enhancing joint stability for movement regulation during motor learning activities. In normal aging, greater muscle co-activation is induced during gait in elderly adults. This study investigated age-related changes in muscle co-activation and spatio-temporal parameters during gait and identified the relationship between muscle co-activ...

OBJECTIVE To find the characteristics of elderly gait, we compared the elderly walking at a moderate speed with the young adult walking at a slow, moderate, and fast speed. METHODS 3D gait analysis was performed on 15 elderly and 15 young adults. Temporo-spatial, kinematic, and kinetic parameters were obtained. Self-selected moderate speed of the elderly walking was compared with self-selecte...

Perchlorate (ClO4) has been detected in some states in the U.S and become an environmental concern since the late 1990’s. Perchlorate properties, contamination, and health effects were introduced in this paper. Perchlorate biodegradation degradation were introduced and summarized. According to recent studies, perchlorate respiring bacteria are present in natural environments, providing possibil...
