Accounting for mating system and group size, gibbon populations at sites with lower group densities, and therefore fewer neighbouring groups, were more likely to exhibit larger home ranges.
This provides indirect evidence for a 'disturbance' effect regulating gibbon social organization, with lower group densities more likely to occur in threatened species due to their typically small population sizes.
The low cytotoxicity of Pluronic-PEI and Pluronic-PEI-DR5-TAT may be the result of the lower amino group density compared to HMW PEI.
Related to this, we asked about discrete episodes of racism and discrimination, but we were unable to assess aspects of "everyday racism" 39 or the effect of belonging to a stigmatised group living in areas of lower own-group density.
37 However, it has also been suggested that people living in areas of lower own-group density may feel marginalised as a result "of a high degree of cohesion among the majority group" 38 and this could result in adverse mental health.
While the two classes of compounds share many structural features, including an abundance of carboxy, hydroxy, phenolic, and ketonic groups, FA has a lower molecular weight, a higher functional group density, and higher acidity than HA.
However, black Caribbean people living in areas of higher own-group density reported more employment related discrimination than those living in areas of lower own-group density.
High permeability of PPO among aromatic polymeric membranes can be attributed to the ether linkages, which introduce more flexibility to the polymer chain, steric hindrance of the methyl groups and lower packing density due to the absence of polar groups [47, 48].
Delay in alendronate initiation (as in the placebo alendronate group) resulted in lower bone density and decreased suppression of bone markers compared to early treatment.
Meanwhile, cell proliferation assay results showed that the cells with low mtDNA copy number proliferated slowly and had a lower cell density than the control group at 108 h even though the two groups had the same initial seeding density.
