Calcium looping example, adding Ca-looping to all coal-fired plants in the UK would generate enough waste for 33 Mtonnes/yr of cement production, whereas current cement production in the UK is only 12.5 Mtonnes/yr. Hence, if the technology is applied on a large scale, the purge rate of CaO should be optimized to minimize waste. To fully gauge the viability of calcium looping as a capture process, it is necessary to consider the political, environmental, and health effects of the process as well. Though many recent scientific reports (e.g.: the seven-wedge stabilization plan by Pacala and Socolow) convey an urgent need to deploy
Urinary calcium Urinary calcium Urinary calcium is calcium in the urine. It is termed -calcuria or -calciuria as a suffix. In a urinalysis, the normal amount of urinary calcium can be measured in amount per time (commonly per 24 hours). It can also be measured in amount per mass of creatinine, which avails for estimating the urinary calcium excretion in a spot urine sample, because urinary creatinine clearance is relatively unaffected by differences in free water clearance which occurs, for example, in dehydration and which would distort the interpretation of the urinary calcium in a spot urine sample. Normally, in an average
