After stirring continually for 45 min, diluted ethanol (final concentration 70% v/v) was added slowly at a speed of 0.2 mL/min to attain final ethanol concentration of 90% in the mixture.
In this study, a polysulfide rubber emulsion was synthesized through the pre-emulsification of polysulfide rubber by mixed-emulsifiers and polyvinyl alcohol as a weight stabilizer and the emulsification by adding deionized water dropwise at a speed of 1 ml/min, stirring at a speed of 1500 rpm and adjusting pH to 8 by ammonia.
And although an $8 billion investment for high-speed rail, added at the last minute to the stimulus package, may seem like a way to get back on track, transportation experts say that amount is not enough for a single bullet train.

The bill, which lays out the direction of the nation's space program for the next three years, would add at least one more space shuttle flight, speed development of a heavy-lift rocket and move ahead with building a spacecraft to venture beyond low-Earth orbit.
We're not adding jobs at breakneck speed, for sure, and we're still repairing the damage done by the great recession to the living standards of millions.
In order to reach his target, he will need to aggressively roll out cable modems to add at least 3 million customers for high-speed Internet access.
