The small excavation area yielded a lithic assemblage, a carcass of Palaeoloxodon antiquus, and some other faunal remains. The main objectives of the study are to better(More)
We have done a spectroscopical analysis of the type I planetary nebula (PN) NGC 5315, through high-resolution (R∼40000) optical spectroscopy with UVES at the 8.2m Very Large Telescope, and medium-resolution (R∼4800) near-IR spectroscopy with FIRE at the 6.5m Magellan Baade telescope, covering a wide spectral range from 0.31 μm to 2.50μm. The main aim of(More)
This study examined classroom environment and locus of control in identifying successfully children showing high and low self-concepts. In their respective intact classrooms, 107 fourth- and fifth-graders were administered the Piers-Harris Children's Self-concept Scale, the Classroom Environment Scale, and the Nowicki-Strickland Children's Locus of Control(More)
