Oil field operators can use several practical equations for calculating flow rates of natural gas through venturi gas-lift valves. For critical flow, this analysis derived such equations from a ...

Because race is a social construct, not a physical characteristic, the race coefficient may not be needed to calculate eGFR. Removing the race coefficient could increase the number of black ...

Current equations for estimated glomerular filtration rate (eGFR) that use serum creatinine or cystatin C incorporate age, sex, and race to estimate measured GFR. However, race in eGFR equations is a ...

The Federal Reserve meets regularly and sets a target interest rate to keep inflation low and jobs high. But what if an equation could do all the work — and even do a better job? Darian Woods and Mary ...
