Overview of Cosmology with the SKA
(Proceedings of Science, 2014)
The new frontier of cosmology will be led by three-dimensional surveys of the large-scale structure of the Universe. Based on its all-sky surveys and redshift depth, the SKA is destined to revolutionize cosmology, in ...
Radio continuum surveys with square kilometre array pathfinders
(Cambridge University Press, 2013)
In the lead-up to the Square Kilometre Array (SKA) project, several next-generation
radio telescopes and upgrades are already being built around the world. These include APERTIF
(The Netherlands), ASKAP (Australia), ...
Revealing the cold dust in low-metallicity environments: I. Photometry analysis of the Dwarf Galaxy Survey with Herschel
(EDP Sciences, 2013)
Context. We present new photometric data from our Herschel Guaranteed Time Key Programme, the Dwarf
Galaxy Survey (DGS),
dedicated to the observation of the gas and dust in low-metallicity environments. A total of 48 ...
The neutral hydrogen content of galaxies in cosmological hydrodynamic simulations
(Oxford University Press, 2013)
We examine the global HI properties of galaxies in quarter billion particle cosmological
simulations using GADGET-2, focusing on howgalactic outflows impactHI content.We consider
four outflow models, including a new one ...
RuxNb1-xO2 catalyst for the oxygen evolution reaction in proton exchange membrane water electrolysers
(Elsevier, 2013)
Bimetallic catalyst system of ruthenium oxide (RuO2) and niobium oxide (Nb2O5) was prepared using the Adams method and the hydrolysis method. Physical and electrochemical characterizations of the catalysts were studied ...
Platinum overlaid PdCulr/C: an Improved Methanol Oxidation Elextrocatalyst
(ESG, 2013)
A platinum overlaid PdCuIr/C (Pt-PdIrCu/C) anodic catalyst for direct methanol fuel cell was prepared by a two-step reduction method. Transmission electron microscopy (TEM) and X-ray diffraction (XRD) results show that the ...
Strategies for information management in education: some international experience
(AOSIS Open Journals, 2013)
Background: Recent analysis of the management of information and communications technologies in South African education suggests strongly that there is only limited strategic thinking that might guide policy-makers, school ...
New imino-pyridyl nickel (II) complexes: synthesis, molecular structures and application as Heck coupling catalysts
(Elsevier, 2012)
Reactions of imino-pyridyl ligands, (2-pyridyl-2-thiophenemethyl)imine (L1) and (2-pyridyl-2-thiopheneethyl)imine (L2) with NiBr2(DME) gave the corresponding complexes [Ni(L1)Br2] (1) and [Ni(L2)Br2] (2) in good yields. ...
Proteomic mechanisms of drug resistance in Candida cell membrane fractions
(International Association for Dental Research, 2014)
INTRODUCTION: The African continent has the highest burden of HIV infection, accounting for approximately 65% of new infections globally. Oral candidiasis is a major cause of increased morbidity in HIV-infected individuals ...
Anaerobes and bacterial vaginosis in pregnancy: virulence factors contributing to vaginal colonisation
(Multidisciplinary Digital Publishing Institute, 2014)
The aetiology and pathogenesis of bacterial vaginosis (BV) is unclear but it appears to be associated with factors that disrupt the normal acidity of the vagina thus altering the equilibrium between the normal vaginal ...
