The phrase "area concentrations" is correct and usable in written English.
It can be used in contexts related to geography, demographics, or scientific measurements where specific concentrations of something are being discussed within defined areas.
Example: "The study focused on the area concentrations of pollutants in urban environments."
Alternatives: "regional concentrations" or "spatial concentrations".
The following is a list of subject area concentrations available to PhD students in certain programs.
The high gas-liquid interfacial area concentrations lead to high mass transfer rates compared to conventional bubble column reactors.
The results demonstrate that the new bubble generation technique offers high interfacial area concentrations (1000 4500 m2/m3) with sub-millimeter bubbles (500 900 µm) and high overall void fractions (10 60%) in comparison with previous bubble column reactor designs.
In the present work, experiments have been performed in a downflow bubble column reactor with microbubbles generated and dispersed by a novel mechanism to determine the gas-liquid interfacial area concentrations by measuring the void fraction and bubble size distributions.
Microbubbles dispersed in bubble column reactors have received great interest in recent years, due to their small size, stability, high gas-liquid interfacial area concentrations and longer residence times.
Operating parameters such as membrane area, concentrations and flow rates of the feed and draw solutions were evaluated to determine their influence on water permeate flux, operating pressures, and water recovery in continuous operation mode.
The coalition provided information to the casino general manager that included site-specific measurement of employee and visitor PM2.5 personal exposure, area concentrations of airborne nicotine and PM2.5, visitor urinary cotinine, and patron and staff opinions (surveys, focus groups, and a Town Hall meeting).
Such urban area concentrations may thus lead to efficient energy use.
Glycoalkaloid levels in the eyes of potatoes are not high, but if sprouting occurs in that area, concentrations of the chemical will be high, according to Gosselin.
Most household variables related to cookfuel use are likely to directly influence kitchen area concentrations, with living area concentrations in turn, being influenced by respective kitchen area concentrations.
In home #1, living area concentrations remained high.
