3D-QSAR and docking studies of pentacycloundecylamines at the sigma-1 (σ1) receptor
(Elsevier, 2013)
Pentacycloundecylamine (PCU) derived compounds have been shown to be promising lead structures for the development of novel drug candidates aimed at a variety of neurodegenerative and psychiatric diseases. Here we show for ...
Theoretical evolution of optical strong lines across cosmic time
(The American Astronomical Society, 2013)
We use the chemical evolution predictions of cosmological hydrodynamic simulations with our latest theoretical
stellar population synthesis, photoionization, and shock models to predict the strong line evolution of ...
The host haloes of O I absorbers in the reionization epoch
(Oxford University Press, 2013)
We use a radiation hydrodynamic simulation of the hydrogen reionization epoch to study
OI absorbers at z ∼ 6. The intergalactic medium (IGM) is reionized before it is enriched;
hence, OI absorption originates within dark ...
The faint source population at 15.7 GHz - I. The radio properties
(Oxford University Press, 2013)
We have studied a sample of 296 faint (>0.5 mJy) radio sources selected from an area of
the Tenth Cambridge (10C) survey at 15.7 GHz in the Lockman Hole. By matching this
catalogue to several lower frequency surveys (e.g. ...
Mind the gap: Science and engineering education at the secondary–tertiary interface
(Academy of Science of South Africa, 2013)
In the South African higher education sector, there is increasing concern about the poor retention and
throughput rates of undergraduate students. There is also concern that the participation rates in higher
education, ...
Stacked reverberation mapping
(Oxford University Press, 2013)
Over the past 20 years reverberation mapping has proved one of the most successful techniques
for studying the local (<1 pc) environment of supermassive black holes that drive active
galactic nuclei. Key successes of ...
Threats to e-government implementation in the civil service: Nigeria as a case study
(Akamai University, 2012)
The rapid advancement in Information and Communication Technology (ICT) has undoubtedly influenced positive changes in carrying out administrative functions in government institutions. The ICT adoption rate in Africa is ...
The preferentially magnified active nucleus in IRAS F10214+4724 - III. VLBI observations of the radio core
(Oxford University Press, 2013)
We report 1.7GHz very long baseline interferometry (VLBI) observations of IRAS F10214+4724, a lensed z = 2.3 obscured quasar with prodigious star formation. We detect what we argue to be the obscured active nucleus with ...
Probing reionization with LOFAR (Low Frequency Array) using 21-cm redshift space distortions
(Oxford University Press, 2013)
One of the most promising ways to study the epoch of reionization (EoR) is through radio
observations of the redshifted 21-cm line emission from neutral hydrogen. These observations
are complicated by the fact that the ...
Magnesium–carbon hydrogen storage hybrid materials produced by reactive ball milling in hydrogen
(Elsevier, 2013)
Time-resolved studies uncovered kinetics and mechanism of Mg–hydrogen interactions during High energy reactive ball milling in hydrogen (HRBM) in presence of various types of carbon, including graphite (G), activated carbon ...
