To evaluate the effect of acupuncture on the severity of withdrawal reaction during rapid opiate detoxification (ROD), forty adult male subjects addicted to opioids and scheduled for ROD by naloxone were randomly divided into acupuncture and control groups. In the acupuncture group during three consecutive days immediately before induction of ROD, body acupuncture was performed while in the con...

the main purpose of this study is to perform numerical simulation of nanofluids as the coolant in vver-440 fuel rod bundle. the fuel rod bundle contains 60 fuel rods with length of 960 mm and 4 spacer grids. in vver-440 fuel rod bundle the coolant fluid (water) is in high pressure and temperature condition. in the present thermo-hydraulic simulation, water-al2o3 nanofluids containing various vo...
A square splittered and unsplittered rod is placed in a turbulent boundary layer developed over a flat plate. The effect of the resulting disturbances on the local heat transfer coefficient is then studied. In both cases the square rod modifies the flow structure inside the boundary layer. As a result, a stagnation point, a jet and wake area are generated around the square rod, each making a co...
Nano HA rod was synthesized by precipitation method using Ca(NO3)24H2O and (NH4)2HPO4 as starting materials and ammonia solution as an agent for pH adjustment. The Ca/P molar ratio was maintained at 1.67. Then, the effect of different pH (4, 6, 8, 10, 11), different surfactants and different times for dialyses on nano HA rod were studied in this study. The samples were characterized by differen...
One of the most important pattern recognition problems in bioinformatics is the de novo motif discovery. In particular, there is a large room of improvement in motif discovery from eukaryotic genome, where the sequences have complicated background noise. The short segment frequency equalization (SSFE) is a novel treatment method to incorporate Markov background models into de novo motif discove...
Aiming at the low mechanization of paddy field weeding and lack dedicated agricultural machinery for in China, a self-propelled system machine was designed. The overall structure working principle were illustrated analyzed. interaction mechanism wheel-soil during model established, then, wheel traction surface flatness selected as evaluation indexes discrete element simulation experiment. steer...
