Herschel-atlas/Gama: a difference between star formation rates in strong-line and weak-line radio galaxies
(OUP, 2013)
We have constructed a sample of radio-loud objects with optical spectroscopy from the Galaxy
and Mass Assembly (GAMA) project over the Herschel Astrophysical Terahertz Large Area
Survey (Herschel-ATLAS) Phase 1 fields. ...
SignSupport: a limited communication domain mobile aid for a Deaf patient at the pharmacy
(Telkom, 2013)
This paper discusses a prototype for a communication aid on a mobile phone to support a Deaf1 person visiting a public hospital pharmacy. The aim is to prevent problems of non-compliance to treatment due to poor communication ...
Cytotoxic, cytostatic and HIV-1 PR inhibitory activities of the soft coral litophyton arboreum
(MDPI, 2013)
Bioassay-guided fractionation using different chromatographic and spectroscopic techniques in the analysis of the Red Sea soft coral Litophyton arboreum led to the isolation of nine compounds; sarcophytol M (1), alismol ...
A new vanadium (III) complex of 2,6-Bis(3,5-diphenylpyrazol- 1-ylmethyl)pyridine as a catalyst for ethylene polymerization
(MDPI, 2013)
The tridentate ligand 2,6-bis(3,5-diphenylpyrazol-1-ylmethyl)pyridine,
abbreviated as 2,6-[(3,5-ph2pz-CH2)2-py], a new pyridine-pyrazole derivative, was
prepared from 2,6-bis(bromomethyl)pyridine and 3,5-diphenylpyrazole. ...
Molecular adaptation mechanisms employed by ethanologenic bacteria in response to lignocellulose-derived inhibitory compounds
(Ivyspring, 2013)
Current international interest in finding alternative sources of energy to the diminishing supplies of
fossil fuels has encouraged research efforts in improving biofuel production technologies. In
countries which lack ...
Existence domains of dust-acoustic solitons and supersolitonsExistence domains of dust-acoustic solitons and supersolitons
(AIP PublishingAIP Publishing, 2013)
Using the Sagdeev potential method, the existence of large amplitude dust-acoustic solitons and
supersolitons is investigated in a plasma comprising cold negative dust, adiabatic positive dust,
Boltzmann electrons, and ...
An exploratory look at associated factors of poverty on educational attainment in Africa and in-depth multilevel modelling for Namibia.
(BER, 2013)
This study examines several indicator variables related to education
and poverty in Africa from the Demographic and Health Surveys
(DHS). Many have described income and education as one of the
fundamental determinants ...
Marrubiin
(MDPI, 2013)
The ethno-medicinal approach to drug discovery represents one of the most
important sources of new and safe therapeutic agents to the challenges confronting modern
medicine and daily life. Many of the traditionally ...
Effect of ni core structure on the electrocatalytic activity of pt-ni/c in methanol oxidation.
(MDPI, 2013)
Methanol oxidation catalysts comprising an outer Pt-shell with an inner Ni-core supported on carbon, (Pt-Ni/C), were prepared with either crystalline or amorphous Ni core structures. Structural comparisons of the two forms ...
Synthesis of zeolites Na-P1 from South African coal fly ash: effect of impeller design and agitation
(MDPI, 2013)
South African fly ash has been shown to be a useful feedstock for the synthesis
of some zeolites. The present study focuses on the effect of impeller design and agitation
rates on the synthesis of zeolite Na-P1 which are ...
