conclusions kannada children with rd were particularly poor on simultaneous and successive processing. our results support the heterogeneity view of rd. results independent-samples t tests (two-tailed) showed significant difference between the groups on all the pass component subtests. the pass scores of children with rd were scattered unevenly around the average to well below the average range...

We investigated mercury sensitization in relation to urinary and hair mercury concentrations. Patch tests were performed on 215 medical students and these tests demonstrated that 28 students were mercury-sensitized (13.0%). Life-styles were studied by questionnaire in 26 of the mercury sensitized students and 46 of the non-sensitized subjects. Urinary mercury concentrations were measured in 25 ...

In addition to the time-dependence of the msd, also the self-part of the van Hove correlation function Gs(r, t) is an interesting measure to characterize anomalous diffusion. Here, Gs(r, t) is the probability that a particle has moved within a time span t a distance r. The Gs(r, t) for a proton on a surface (figure S1) shows that the surface displacement exhibits long-tailed behavior with respe...
