The actual RF level from each source depends on the details of the exposure location (i.e., distance from the antenna), but the last column lists whether the source is more ubiquitous and universal (U) or more limited and local (L); a "+" indicates that this source would typically contribute a significant fraction of ambient RF background levels.
Importantly, even with this reduction in overdispersion, the factor BRAIN did not contribute a significant improvement to the fit by the source regions themselves (V1: F4,25 = 0.27, P = 0.89; V2: F2,12 = 1.39, P = 0.29; V4: F2,14 = 1.12, P = 0.35).
Their model results suggested that combustion sources of iron contribute a significant amount of soluble iron deposition over oceans downwind of industrialized and biomass burning regions, because of high iron solubility.
The set of urease proteins play an important function in acid resistance while also contributing a significant nitrogen source [ 53, 63].
Although concern over linear wear predominates with contemporary designs, if initial liner engagement is compromised or locking mechanism failure occurs with time, the convex insert surface again may become a significant source of debris contributing to osteolysis.
At the same time, remittances sent by migrants living in the U.S. are a significant source of income, contributing to the fiscal health of the citizens as well as the governments in the region.
Breed was a significant source of variation (P < 0.01) contributing to 10.54% of the total variation; the remaining 89.46% of variation was within breeds.
The stoves are a significant source of black carbon in the atmosphere, contributing to climate change.
