But soon after, I developed a novel mathematical model which can be used by doctors and environmental specialists to quantify the effect ofthe pollutants on the lung function as measured by thepeak expiratory flow rate-- which is essentially how much a person can breathe out in one breath.
The thought ten years ago was that they would mostly be charged at night, filling in the valley of low off-peak demand, and thus allowing more kilowatt-hours to flow across the same infrastructure.
