Similar to the indirect effect, the total effect on total suspended particles, dissolvedoxygendemand, and suspended solids is strongest in poor countries.
From theCambridge English Corpus
Most conditions will benefit from bed rest (reducing theoxygendemand) and oxygen therapy (increasing the oxygen supply).
From theCambridge English Corpus
An important result is that at low income levels there is a strong positive indirect effect of corruption on total suspended particles, dissolvedoxygendemand, and suspended solids.
From theCambridge English Corpus
Significant positive coefficients are found for dissolvedoxygendemand, suspended solids, and volatile organic carbon emissions.
From theCambridge English Corpus
Increasing dissolvedoxygendemand(or likewise decreasing dissolved oxygen concentration) indicates contamination by organic carbon contained in sewage, industrial discharges, or the runoff from agricultural areas.
From theCambridge English Corpus

From theCambridge English Corpus
Bed rest and oxygen therapy should be instituted if decompensating to decrease theoxygendemandand lessen the shunt respectively (oxygen is a powerful pulmonary vasodilator).
From theCambridge English Corpus
