Regularities of electroflotation process of a mixture of slightly soluble compounds (Ce, La, Nd, Pr, Sm) from model solutions of man-made effluents are established. The role of the influence of cationic additives SeptoPAV XSV.50 and Superfloc 494 on the indexes of efficiency of the electroflotation process was determined. The influence of pH and concentration of Na2CO3 precipitator were established on the efficiency of electroflotation extraction of a 5-component mixture of cerium group metals, which allows determining the feasibility of the industrial electroflotation process for the extraction of insoluble compounds.

<p></p><p>In the present experimental study different interaction ‘modes’ those took place between a psychologist and a child were tested for the role of these towards health recovery of the child? Following were the interaction modes, a) presenting a flower with smile plus inquiring about health, b) offering a blessing plus inquiring about health, c) making an indifferent presence plus inquiring about health with flat tone, d) inquiring about health with providing precautions about prognosis. It was assumed that all modes would differently influence health outcomes? 100 hospitalized children located in child wards of different hospitals with randomized pre-post block design interacted. One each from four interaction modes was used for a group of 25 participants each. Actual ward discharge was compared with anticipatory estimated by each ward in-charge to calculate effect of mode on outcome. Face Pain Scale, The Children Happiness Scale and a Demographic Sheet were also used. Results reflected ‘modes’ relationship with outcomes. More studies would clarify further.</p><br><p></p>

Misinformation often continues to influence people’s cognition even after corrected (the ‘continued influence effect of misinformation’, the CIEM). This study investigated the role of information relevance in the CIEM by questionnaire survey and experimental study. The results showed that information with higher relevance to the individuals had a larger CIEM, indicating a role of information relevance in the CIEM. Personal involvement might explain the effects of information relevance on the CIEM. This study provides insightful clues for reducing the CIEM in different types of misinformation and misinformation with varying relevance.

This study addresses respiratory and motor impairments in an experimental reserpine-induced model of parkinsonism in rats. The role of chronic hypoxia due to diminished ventilation in the development and course of neurodegeneration is addressed. An attempt was made to distinguish between central and peripheral dopamine pathways in the mechanisms of neurodegeneration. A dissociation of putative mechanisms of respiratory and motor impairments is tackled as well. Although this purely experimental study cannot be directly extrapolated to human pathophysiology, the corollaries have been drawn concerning the potential repercussions of the respiratory and motor impairments for the physiotherapeutic procedures in the management of chronic neurodegeneration.

ABSTRACT Whistleblowing reports, if properly investigated, facilitate the early detection of fraud. Although critical, investigation-related decisions represent a relatively underexplored component of the whistleblowing process. Investigators are responsible for initially deciding whether to follow-up on reports alleging fraud. We report the results of an experimental study examining the follow-up intentions of highly experienced healthcare investigators. Participants, in the role of an insurance investigator, are asked to review a whistleblowing report alleging billing fraud occurring at a medical provider. Thus, participants are serving as external investigators. In a between-participant design, we manipulate the report type and whether the caller previously confronted the wrongdoer. We find that compared to an anonymous report, a non-anonymous report is perceived as more credible and follow-up intentions stronger. We also find that perceived credibility fully mediates the relationship between report type and follow-up intentions. Previous confrontation is not significantly associated with either perceived credibility or follow-up intentions. Data Availability: Data are available upon request.

Using semiempirical MNDO method of quantum chemistry the optimal geometries and corresponding electronic structures of [Pb3(OH)n]6-n model systems as well as of their hydrated [Pb3(OH)n(H2O)8-n]6-n analogues (n = 4, 5) are investigated. The most stable trinuclear lead(II) complexes present in aqueous solutions correspond to cyclo-(μ3-OH)(μ2-OH)3Pb32+, Pb(μ-OH)2Pb(μ-OH)2Pb2+, cyclo-(μ3-OH)2(μ2-OH)3Pb3+, Pb(OH)(μ-OH)2Pb(μ-OH)Pb(OH)+ and Pb(OH)(μ-OH)2Pb(μ-OH)2Pb+ systems. The key role of OH bridges (by vanishing direct Pb-Pb bonds) on the stability of individual isomers is discussed.
