A mass fitted in front of the hinges of the control surfaces in such a way as to move the center of gravity (CG) of the control to a point forward of the hinge point to prevent flutter at very high speeds. The aim of providing a mass balance is not for the control to be balanced in the sense of a remaining level but to alter the mass distribution of the control to avoid any variation or flutter.

assert that DDT applied indoors does not move easily from the application site; however, a mass balance model indicates that 60% to 80% of the DDT ends up outdoors within 6 months (K.
Consumer-food interactions can therefore be evaluated in terms of the flows of essential nutrients between ecosystem components that must conform to the constraints of mass balance and stoichiometry (Sterner 1995).
To investigate this seeming paradox, transects were run along the entire 40-km length of the river to determine where nutrients were being removed, and a mass balance budget of nutrients was constructed for the entire drainage basin.
Although the concept of using calorimetry to study equilibrium changes in controlled reactions is not new, recent advances in electronics allow for the effective measurement of matter and energy transfer in a continuously flowing stream to quantify mass balance relationships.

The mass balance supply chain model administratively monitors the trade of RSPO-certified oil palm products throughout the entire supply chain, which allows stakeholders throughout the process to demonstrate their commitment to sustainable palm production and trade.
Antarctic snowfall totals are useful in understanding the mass balance of its ice sheets as well as their influence on sea levels, so the study has important implications in these research areas.
Melting was the third most extensive since 1979 and the glacier's 'mass balance'--the amount of snow gained minus the snow and ice that melted away, tied with last year's record value.
