Political Psychology, Volume 47, Issue 4, August 2026.Abstract When do people challenge economic inequality and when are they more likely to accept it? Whether people justify inequality is key to challenging or accepting it, but research is inconclusive on how objective economic inequality is related to individuals' justification of inequality.

Permeability of demineralized dentin to HEMA
Dental Materials, 2000The objectives of this study were to develop a macromodel of the demineralized layer of dentin that is formed after acid-etching, and to determine if the amount of HEMA uptake was responsive to air drying. The hypothesis that was tested was that HEMA uptake by demineralized dentin depends upon the degree of expansion of the collagen fibril network ...

Advanced Composites and Hybrid Materials, 2021
In the present study, the adsorption removal of anionic (MO) and cationic (MB) dyes with GO/HEMA and GO/HEMA/TiO2 and GO/Fe3O4/HEMA nanocomposites as adsorbents was investigated. Characterization of properties was determined by FTIR, XRD, SEM, TEM, EDX, and zeta potential analysis.

Toxicokinetic of HEMA in guinea pigs
Journal of Dentistry, 2002Unconverted 2-hydroxyethylmethacrylate (HEMA) can be released from dental resin materials and can enter the body in humans. In the present study the uptake, distribution and excretion of 14C-HEMA applied via different routes were examined in vivo in guinea pigs.HEMA (0.02 mmol/kg bw labelled with a tracer dose 14C-HEMA 0.3 Bq/g bw) was administered by ...

Effects of HEMA on water evaporation from water–HEMA mixtures
Dental Materials, 1998The aims of this research were: (1) to determine the relative rates of evaporation of water and HEMA, and (2) to determine the effects of increasing concentrations of HEMA on the rate of evaporation of water from water and HEMA mixtures.Ten microliters of each solution (100% H2O, 75% H2O-25% HEMA, 50% H2O-50% HEMA, 25% HEMA, 100% HEMA) were placed on ...

HEMA reactivity with demineralized dentin
Journal of Dentistry, 20102-Hydroxyethylmethacrylate (HEMA) was compared to its epoxy analogue, glycidoxypropylmethacrylate (GMA), for reactivity with 2,6-diaminohexanoic acid (Lysine), an amino acid present in collagen possessing a reactive amino side chain. The aim was to verify whether HEMA could chemically react with collagen fibers.Capillary electrophoresis was used to ...

Effect of HEMA on bonding to dentin
Dental Materials, 1992The present study investigated the effectiveness of treating dentin with 2-hydroxyethyl methacrylate (HEMA) prior to application of an adhesive resin. The adhesive resin was 5% 4-methacryloxyethyl trimellitate anhydride (4-META) in methyl methacrylate (MMA) combined with poly-MMA powder. Polymerization of this resin was initiated by tri-n-butyl borane (
