Attentional bias and emotion in older adults: Age-related differences in responses to an emotional Stroop task

Abstract: The purpose of the study was to examine whether older adults show an emotional interference effect in a Stroop task, and whether their RTs differ with regard to age, gender and tendencies of mood regulation (to improvement and/or deterioration). The sample consisted of 60 participants at the age from 65 to 85. Emotional version of Stroop task and the Mood Regulation Scales were used. The results showed no significant differences in RTs to emotional and neutral words. Unexpectedly, a speeding effect was observed with the age of women. It appeared also that the effect of mood regulation tendencies was not significant for RTs. The last two effects are not consistent with the literature on cognitive and emotional aging.

Electrostatic separation of binary mixtures of some biodegradable polymers and poly(vinyl chloride) or poly(ethylene terephthalate)

Abstract: There are presented results of investigation of electrostatic separation of binary mixtures containing a biodegradable polymer {polylactide (PLA), polycaprolactone (PCL), or poly(3-hydroxybutyrate-co-4-hydroxybutyrate) [P(3,4HB)]} and a commonly used polymer [poly(vinyl chloride) (PVC) or poly(ethylene terephthalate) (PET)]. It was found that the binary mixtures of these polymers could be efficiently separated. The electrostatic separation process of the P(3,4HB)/PET mixture appeared to be most successful. It is indicated that the share of a biodegradable component in the mixture essentially influences the separation effects. Therefore, suitable choice of necessary conditions is needed to perform the separation process, which includes appropriate separator settings, depending on fractions of individual components in the mixture being separated.

Accurate calculation of the intensity dependence of the refractive index using polarized basis sets.

Abstract: Using the single and double excitation coupled cluster level of theory (CCSD) and the density functional theory/Becke 3-parameter Lee-Yang and Parr (DFT/B3LYP) methods, we test the performance of the Pol, ZPol, and LPol-n (n = ds, dl, fs, fl) basis sets in the accurate description of the intensity dependence of the refractive index in the Ne atom, and the N2 and the CO molecules. Additionally, we test the aug-pc-n (n = 1, 2) basis sets of Jensen, and the SVPD, TZVPD, and QZVPD bases by Rappoport and Furche. Tests involve calculations of dynamic polarizabilities and frequency dependent second hyperpolarizabilities. The results are interpreted in terms of the medium constants entering the expressions for optically induced birefringences. In all achiral systems, the performance of the LPol-n sets is very good. Also the aug-pc-2 set yields promising results. Accurate CCSD results available in the literature allow us to select the best basis sets in order to carry out DFT/B3LYP calculations of medium constants in larger molecules. As applications, we show results for (R)-fluoro-oxirane and (R)-methyloxirane.
