Hot subdwarf stars in close-up view IV. Helium abundances and the 3He isotopic anomaly of subdwarf B stars
(EDP Sciences, 2013)
Atmospheric parameters and helium abundances of 44 bright subdwarf B stars have been determined. More than half of our sample consists of newly discovered stars from the Edinburgh Cape survey. We showed that effective ...
Using the human capabilities approach as a normative framework to evaluate institutional teaching and learning interventions at UWC
This article uses the human capabilities approach to evaluate an institutional approach to teaching and learning at the University of the Western Cape (UWC). The human capabilities framework makes it possible to examine ...
Self-Catalytic growth of tin oxide nanowires by Chemical Vapor Deposition Process
We report on the synthesis of tin oxide (SnO2) nanowires by a chemical vapor deposition (CVD) process. Commercially bought SnO nanopowders were vaporized at 1050∘C for 30 minutes with argon gas continuously passing through ...
