Mining the Herschel-Astrophysical Terahertz Large Area Survey: submillimetre-selected blazars in equatorial fields
(Oxford University Press, 2013)
The Herschel-Astrophysical Terahertz Large Area Survey (H-ATLAS) provides an unprecedented
opportunity to search for blazars at sub-mm wavelengths. We cross-matched the Faint
Images of the Radio Sky at Twenty-cm (FIRST) ...
The effect of PtRuIr nanoparticle crystallinity in electrocatalytic methanol oxidation
(MDPI, 2013)
Two structural forms of a ternary alloy PtRuIr/C catalyst, one amorphous and one highly crystalline, were synthesized and compared to determine the effect of their respective structures on their activity and stability as ...
HerMES: Candidate gravitationally lensed galaxies and lensing statistics at submillimeter wavelengths
(American Astronomical Society, 2013)
Gravitational lensing increases the angular size and integrated flux of affected sources. It is exploited to investigate the mass distribution of the foreground lensing structures and the properties of the background lensed ...
Thermal conductivity and temperature profiles of the micro porous layers used for the polymer electrolyte membrane fuel cell
(Elsevier, 2013)
The thermal conductivity and the thickness change with pressure of several different
micro porous layers (MPL) used for the polymer electrolyte membrane fuel cell (PEMFC)
were measured. The MPL were made with different ...
Self-catalytic growth of tin oxide nanowires by chemical vapor deposition process
(Hindawi, 2013)
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 ...
Reviewing evidence of marine ecosystem change off South Africa
(National Inquiry Services Centre, 2013)
Recent changes have been observed in South African marine ecosystems. The main pressures on these
ecosystems are fishing, climate change, pollution, ocean acidification and mining. The best long-term datasets are
for trends ...
Trends in Genotypic HIV-1 Antiretroviral resistance between 2006 and 2012 in South African Patients receiving first- and second line antiretroviral treatment regimensTrends in Genotypic HIV-1 Antiretroviral resistance between 2006 and 2012 in South African Patients receiving first- and second line antiretroviral treatment regimens
(University of the Western CapePublic Library of Science -- PLoS, 2013)
South Africa's national antiretroviral (ARV) treatment program expanded in 2010 to include the nucleoside
reverse transcriptase (RT) inhibitors (NRTI) tenofovir (TDF) for adults and abacavir (ABC) for children. We ...
Amorphous Pt@dCu/CNT catalyst for methanol elextrooxidation
(South African Chemical Institute (SACI), 2013)
A multi-walled carbon nanotube-supported, Pt decorated nano-sized amorphous PdCu alloy cores (denoted as Pt@PdCu/CNT)
catalyst with lower Pt loading is synthesized via a galvanic displacement reaction. The structure is ...
South African seaweed aquaculture: A sustainable development example for other African coastal countries
(Academic Journals, 2013)
The green seaweed Ulva is one of South Africa's most important aquaculture products, constituting an
important feed source particularly for abalone (Haliotis midae L.), and utilized as a bioremediation tool
and other ...
Herschel-ATLAS/GAMA: What determines the far-infrared properties of radio galaxies?
(OUP, 2013)
We perform a stacking analysis of Herschel Astrophysical Terahertz Large Area Survey
(H-ATLAS) data in order to obtain isothermal dust temperatures and rest-frame luminosities
at 250 µm (L250), for a well-defined sample ...
