Cooling rate represents the rate of change of temperature over time during solidification process. The cooling rate or rate of heat flow has a profound effect on the properties of final product. Subsequently, it can be expected that higher pouring temperature (740oC) corresponding to lower cooling rate decreases surface quality of castings.

QOS scheme are balance O/O scheme, where the correlation between any set-1 and set-2 users are equalized. The allowable overload of this scheme is investigated in the uplink on an AWGN and Rayleigh fading channels, so that the uncoded performance with iterative multistage interference cancellation detector remains close to the single user bound.

2013-4-1 · The highest conversion was 85% in a packed bed reactor, and the optimal condition was 75 °C reaction temperature and 20 h reaction time. But the conversion reduced to 65% in the next run and remained constant for up to 140 h. They concluded that the oxidation of WO 3 was the main reason for the low performance.

Samples (10 g) were heated (570°C, 30 min) in a muffle and then digested (50 min) in boiling 1:1 aqua regia (80 ml). After evaporation almost to dryness, concentrated HCl (10 ml) was added and brought to the boil. After cooling, the leachate and undissolved residue were made up to 250 mL with water.

A sample volume of 15 mL resulted in a pre-concentration factor of 120, and precision at the 500 and 50 µg L-1 levels was±3.1 and±3.3% (RSD), respectively. The procedure was applied to mineral water, spring water, river water, and vitamin B-12 and accuracy was assessed through a recovery experiment.
