Two scenarios demonstrate the need to use the percent of parent drug loss rather than the percent of degradation products formed when reconciling mass balance calculations. Mass balance correlates the ...

Continental crust is buoyant compared with its oceanic counterpart and resists subduction into the mantle. When two continents collide, the mass balance for the continental crust is therefore assumed ...

ORLANDO, Fla.—For chemical recycling to work effectively, some plastics and consumer product companies say governments need to embrace very technical but important standards called mass balance.

The authors omitted to cite a paper 5 that used a crustal mass-balance approach, but alternative constraints on paleogeography and pre-collisional crustal geometries, to argue that about 40 to 50% of ...
