Summary: Response surface methodology (RSM) has been used to optimize the effect of circulation rates
, ozone supply, cephalexin (CEX) concentration, and granular activated carbon (GAC) dose on removal of COD from solution.
In the Eighteenth Central Committee all but ninety-one members were replaced, increasing the circulation rate
slightly from the Seventeenth Central Committee's 54.9 percent to 55.6 percent today.
For the cooling experiment, the groundwater circulation rate
was about 33 L/min, and the heat-source water circulation rate
was about 70 L/min.
The library's fiscal year 2010 budget is around $4.3 million, with the addition of some PILOT money from Worcester Polytechnic Institute, down about 10 percent from $4.8 million in fiscal year 2009.The economy can make things difficult for funding, but it helps that the library's circulation rate
He was Worldwide Circulation Director of Life Magazine and in 1957 he founded Life Circulation Corporation, a wholly owned subsidiary of Time, charged with maintaining an 8-million circulation rate
base for Life Magazine.
The input data used for the IADC-Neural Network design were consisted of bit size, total nozzle area of the bit, depth when the bit was pulled, drilled interval length, rate of penetration, maximum and minimum weight on bit (WOB) and rotary speed (RPM), and the mud circulation rate
; while the target was the bit type (IADC code).
The superficial gas velocity, [U.sub.g], ranges from 3.5 to 8 m/s and solids circulation rate
, [G.sub.s], ranges from 50 to 200 kg/([m.sup.2] s).
Third, we have been able to increase our circulation rate
base for the first time in more than 45 years.
Seven operating factors under investigations included bed temperature, excess air factor, particle size, secondary air ratio, Ca/S ratio, circulation rate
, and bed material height.
Reactor performance was assessed for the condition without liquid circulation as well as at a superficial circulation rate
The researchers hypothesize that elevated Caribbean salinity, which is transported via the Gulf Stream to the North Atlantic, amplifies the heat transport system by increasing the deep-ocean circulation rate
. When the North Atlantic Ocean cools, the Caribbean's salinity begins building up because the deep ocean circulation drops to a fraction of its previous rate and the Gulf Stream no longer transports salty water away.
