Synthesis and optimisation of IrO2 electrocatalysts by Adams fusion method for solid polymer electrolyte electrolysers
(Bentham Science Publishers, 2012)
IrO2 as an anodic electrocatalyst for the oxygen evolution reaction (OER) in solid polymer electrolyte (SPE) electrolysers was synthesised by adapting the Adams fusion method. Optimisation of the IrO2 electrocatalyst was ...
On multiple classes of gamma-ray bursts, as deduced from autocorrelation functions or bivariate duration/hardness ratio distributions
(Oxford University Press, 2012)
Autocorrelation functions (ACFs) of 119 gamma-ray bursts (GRBs) monitored by the Burst
Alert Telescope (BAT) on Swift are calculated. Contrasting with previous results for smaller
numbers of bursts from other missions, ...
Estimation of the coherence time of stochastic oscillations from modest samples
(Oxford University Press, 2012)
‘Quasi-periodic’ or ‘solar-like’ oscillations can be described by three parameters – a characteristic
frequency, a coherence time (or ‘quality factor’) and the variance of the random
driving process. This paper is concerned ...
Book review: urban geology
(Springer Verlag, 2012)
Nodulation, leaf harvesting intensity and interval of the black-eyed bean (BEB) (Vigna unguiculata L. Walpers) cowpea type at the University of Zimbabwe, Harare, Zimbabwe
(Academic Journals, 2012)
A glasshouse pot experiment was carried out at the University of Zimbabwe, Crop Science Department in 2006 to 2007 rainy season to determine the effect of leaf harvesting intensity and interval on cowpea biological nitrogen ...
Fifth order two-stage explicit Runge-Kutta-Nystrom method for the direct integration of second order ordinary differential equations
(Academic Journals, 2012)
In this paper a direct integration of second-order Ordinary Differential Equations (ODEs) of the form using the Explicit Runge-Kutta-Nystrom method with higher derivatives is presented. Various numerical schemes are derived ...
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 ...
Evaluating SMS parsing using automated testing software
(Institute of Electrical and Electronics Engineers (IEEE) Inc., 2012)
Mobile phones are ubiquitous with millions of users acquiring them every day for personal, business and social usage or communication.
Its enormous pervasiveness has created a great advantage for its use as a technological ...
BANA-positive plaque samples are associated with oral hygiene practices and not CD4+ T cell counts in HIV-positive patients
(Hindawi Publishing Corporation, 2012)
Background. The “red complex” microorganisms, namely, Porphyromonas gingivalis, Treponema denticola, and Tannerella forsythia
are considered as potential pathogens causing HIV-associated periodontal diseases. Moreover, ...
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. ...
