in the present work, highly efficient oxidation of sulfides catalyzed by moo2(acac)2 supported on multi-wall carbon nanotubes, mwcnts, modified with 1,2-diaminobenzene (dab) and 2-aminophenol (ap), at room temperature are reported. the effects of various parameters such as reaction time, solvent, catalyst amount, oxidant, etc, were studied. these heterogenized catalysts showed high activity in ...

OBJECTIVE The literature on gifted and talented children is limited. Little is known about the types and nature of difficulties experienced by gifted and talented children, and even less known about parenting issues related to parenting a gifted and talented child. The aim of the present study was to describe children's behavioural and emotional adjustment, and the factors that contribute to ch...

supported catalysts synthesized via the interaction of mg(oet)2 with ticl4 in the presence or absence of an internal stereoregulating donor (di-n-butyl phthalate), with different solvents (chlorobenzene, n-undecane, n-heptane) at different titanation temperatures have been studied by a set of physicochemical methods. data on the chemical composition, x-ray structure and pore structure of these ...

humans are born with potential abilities which may emerge due to certain circumstances. in educational environments, needs, interests and capacities of individuals are wide and varied. therefore, developers and educators of training programs must provide special facilities to identify talented people in the way that justice is observed for all people. meanwhile, there is no doubt that technolog...

The introduction to the archival block offers a brief overview of reflections educators, writers, and psychologists on children’s creativity. At beginning 20th century, interest in writing was closely linked solving educational tasks: using genres personal (diary, letter, handwritten album/journal), educators hoped develop students’ written speech. same time, began be endowed with independent v...
