Heat transfer mechanisms and the solidification process are simulated for a continuous casting machine and the geometric shape of the liquid pool is predicted considering different conditions. A heat transfer and solidification model is described for the continuous casting of steel slabs. The model has been established on the basis of the technical conditions of the slab caster in the con...

The mechanisms involved in enzymatic hydride transfer have been studied for years, but questions remain due, in part, to the difficulty of probing the effects of protein motion and hydrogen tunneling. In this study, we use transition path sampling (TPS) with normal mode centroid molecular dynamics (CMD) to calculate the barrier to hydride transfer in yeast alcohol dehydrogenase (YADH) and human...

Simulations of turbulent convection flow adjacent to a two-dimensional backward-facing step are presented to explore the effects of step height on turbulent separated flow and heat transfer. Reynolds number and duct’s height downstream from the step are kept constant at Re0 = 28,000 and H = 0.19 m, respectively. Uniform and constant heat flux of qw = 270 W/m 2 is specified at the stepped wall d...

BACKGROUND Conventional frontalis transfer may cause a range of complications. In order to overcome complications, we made modifications to the surgical technique, and compared the outcomes of patients who underwent conventional frontalis transfer with those of patients who underwent modified frontalis transfer. METHODS We conducted a retrospective study of 48 patients (78 eyes) who underwent...

This paper deals with numerical study of semi-finite incompressible flow of air over two blocks with different heights in the presence of a condensing-source, dispensing- contaminant in the flow, in both steady and unsteady states. The numerical solution of governing PDE equations are constructed by a finite-volume method applied on structured grid arrangement. The effects of air flow velocity,...

in this article the effect of fouling on tube side and the overall performance of preheat exchangers of crude distillation unit of petroleum refinery have been investigated. for this purpose the experimental data of australian light crude oil in surface temperature of 200-260oc and the velocity between 0.25 to 0.4 m/s have been used. first, an overall dirty heat transfer coefficient was calcula...

to investigate the effect of dose and applying time of paraquat on soybean weed control, especially wild melon, factorial experiment conducted as a randomized complete block design with four replications in 2009 in dashte naz co. sari-iran. the treatments included different doses of paraquat (0, 1, 1.5, 2 and 2.5 liters per hectare of commercial material) and different growing stages of wild me...

[1] A comparison between the fast radiative transfer model Radiative Transfer for the TIROS Operational Vertical Sounder (RTTOV-7) and the physical radiative transfer model Atmospheric Radiative Transfer Simulator (ARTS) was carried out. Radiances were simulated for the sounding channels of the Advanced Microwave Sounding Unit B (AMSU-B) for the whole globe for a single time of a single day (1 ...

BACKGROUND Estimates of the height of patients in the intensive care unit are required to adhere to clinical guidelines for drug dosages, ventilatory support, and nutrition. The gold standard of standing height cannot be used because these patients are often unconscious and recumbent. The ability of physiotherapists or dietitians to measure height in unconscious, recumbent patients has not been...
