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.
Mass balance. Determining the effect of cost-reduction options on manufacturing cost is a primary concern of manufacturing engineers.
Mass balance studies chart a pollutant's path by comparing the amount of the chemical in the air, water and soil with how much has been released.
Among their topics are
mass balance and swath displacement evaluations from agricultural application field trials, droplet velocity from broadcast agricultural nozzles as influenced by pulse-width modulation, the impact of plugged venturi nozzle air-inclusion ports on droplet-size distribution, the efficacy of water-conditioning adjuvants for dicamba-tolerant soybean, assessing polymeric drift-reduction adjuvant performance after prolonged exposure to pump-induced shear, and the role of interfacial rheology in agricultural drift control.
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.
Mass balance of glaciers other than the ice sheets.
