Towards communication and information access for deaf people
(SAICSIT, 2014)
In tightly circumscribed communication situations, an interactive system resident on a mobile device can assist Deaf people with their communication and information needs. The Deaf users considered here use South African ...
Electrochemically reduced graphene oxide pencil-graphite in situ plated bismuth-film electrode for the determination of trace metals by anodic stripping voltammetry
(ESG, 2014)
An electrochemical platform was developed based on a pencil-graphite electrode (PGE) modified with electrochemically reduced graphene oxide (ERGO) sheets and in conjunction with an in situ plated bismuth-film (ERGO-PG-BiE). ...
Carcinoembryonic antigen immunosensor developed with organoclay nanogold composite film
(ESG, 2014)
Organoclay nanogold composite were prepared using gold nanoparticles and the natural Cameroonian clay grafted with amino organosilane. The functionnalization of clay provided abundant amino group to assemble gold nanoparticles. ...
Beef-derived mesoporous carbon as highly efficient support for PtRuIr electrocatalysts and their high activity for CO and methanol oxidation
(SACI, 2014)
In this work, a low-cost and nitrogen-containing carbon with mesoporous pores and high surface area was synthesized by
carbonizing a natural biomass precursor, i.e. beef. It is found that the prepared material has excellent ...
An optimal portfolio and capital management strategy for basel III compliant commercial banks
(Hindawi Publishing Corporation, 2014)
We model a Basel III compliant commercial bank that operates in a financial market consisting of a treasury security, a marketable security, and a loan and we regard the interest rate in the market as being stochastic. We ...
Optical-faint, far-infrared-bright Herschel sources in the CANDELS fields: Ultra-luminous infrared galaxies at z > 1 and the effect of source blending
(American Astronomical Society, 2014)
The Herschel very wide-field surveys have charted hundreds of square degrees in multiple far-IR
(FIR) bands. While the Sloan Digital Sky Survey (SDSS) is currently the best resource for optical
counterpart identifications ...
Heavy metals in the irrigation water, soils and vegetables in the Philippi horticultural area in the Western Cape Province of South Africa
(Springer Verlag, 2014)
The aims of this study were to investigate the
extent of heavy metal contamination in the Philippi
horticultural area in the Western Cape Province, South
Africa. Concentrations of Cd, Cr, Cu, Mn, Ni, Pb and Zn
were ...
Application of nano zinc oxide (nZnO) for the removal of triphenyltin chloride (TPT) from dockyard wastewater
(Water Research Commission, 2014)
The use of triphenyltin chloride (TPT), a persistent organic pollutant, as a biocide has led to serious contamination of the marine environment. The potential of nano zinc oxide (nZnO) for the removal of TPT from contaminated ...
Effect of the metabolic syndrome on male reproductive function: a case-controlled pilot study
(Wiley, 2014)
The metabolic syndrome (MetS) is a constellation of various risk factors. This
study aimed to investigate the effect of MetS on testosterone and progesterone,
and semen parameters, in a case-controlled pilot study. Male ...
An O−C (and light travel time) method suitable for application to large photometric databases
(Oxford University Press, 2014)
The standard method of studying period changes in variable stars is to study the timing
residuals or O−C values of light-curve maxima or minima. The advent of photometric surveys
for variability, covering large parts of ...
