four patients were studied for intercostals nerve blockade in cholecystectomy. all of the patients were poor risks (class 4) and received premedication before the procedure. intercostals nerve blockade (icnb) of the 7th and 10th thoracic nerves on the right side was performed with lidocaine 1% plus adrenaline 5 ml. at each segment, t7-t10 (a total dose of 20 ml). ventilation was controlled usin...

Abstract Clogging of submerged entry nozzle (SEN) during continuous casting steel is an undesirable phenomenon leading to different problems like flow blockage, slag entrainment, nonuniform solidification, etc. A transient numerical model for clogging based on Eulerian-Lagrangian approach was developed and it covers the main steps clogging: (a) formation first oxide layer by chemical reactions ...

For successful scramjet engine operations, it is important to understand the mechanism of inlet unstart phenomenon. Among various unstarted flow patterns in hypersonic inlets, low-amplitude oscillatory still unclear. Therefore, present study, characteristics non-oscillatory a inlet-isolator model are studied by using numerical analysis with RANS-based OpenFOAM solver. In results, amplitude pres...

By taking into account the turbine type, terrain, wind climate and layout, effects of wakes other losses, engineering models enable rapid estimation energy yields for prospective existing farms. We extend capability models, such as deep-array wake model, to additional losses that may arise due presence clusters farms, global blockage effect large-scale effects, which become more significant wit...

We investigate the totally asymmetric exclusion process on Z, with the jump rate at site i given by ri = 1 for i 6= 0, r0 = r. It is easy to see that the maximal stationary current j(r) is nondecreasing in r and that j(r) = 1/4 for r ≥ 1; it is a long outstanding problem to determine whether or not the critical value rc of r such that j(r) = 1/4 for r > rc is strictly less than 1. Here we prese...

We analyze the performance of a free-space optical (FSO) link affected by atmospheric turbulence and line-of-sight (LOS) blockage. For this purpose, the atmospheric turbulence induced fading is modeled by the ℳ distribution, which includes the Gamma-Gamma distribution as special case. We exploit the fact that the physical interpretation of the ℳ distribution allows to split the optical energy t...

Whether a state of nasal hyperresponsiveness influences antigen-induced biphasic nasal blockage and sneezing were examined using a guinea pig model of allergic rhinitis. Sensitized animals were challenged with an antigen, Japanese cedar pollen, once every week. Before the 13th challenge, the animals were randomly divided into 2 groups, and then the 13th challenge was performed (Groups A-0 and B...

Abstract High-order large eddy simulations are performed to study the performance and flow fields of a ducted wind turbine (DWT) operating at different tip speed ratios. To evaluate effects duct, with same ratios also on corresponding open-rotor turbine. It is found that consistently obtains higher power outputs than counterpart, duct itself enhances turbulence blade trailing-edge vortices but ...

Cardiovascular diseases were the main cause for loosing lives in last decades due to restricted blood flow states vessels areas. Numerical investigations have been conducted as aim of this work examine flow, and wall shear stresses adjacent mono stenosis up different degrees involved main, side distal branches well observe pulsatile left coronary artery through various percentage stenosis.
