Gravity and Aeromagnetic Studies of the Filabusi Greenstone Belt, Zimbabwe Craton: Regional and Geotectonic Implications
(Scientific Research Publishing Inc., http://www.scirp.org, 2012)
The Filabusi greenstone belt (FGB), Zimbabwe craton, has been geologically remapped relatively recently but its regional tectonic setting and subsurface structure have, until now, remained unresolved. This paper presents ...
Geoelectric Evaluation of Groundwater Potential and Vulnerability of Overburden Aquifers at Onibu-Eja Active Open Dumpsite, Osogbo, Southwestern Nigeria
(Scientific Research Publishing Inc., http://www.scirp.org/journal/JWARP/, 2016)
Electrical resistivity method was used to assess groundwater potential and vulnerability of overburden aquifers at Onibu‐Eja active open dumpsite, Osogbo, Southwestern Nigeria. Eighteen Vertical Electrical Sounding (VES) ...
Absorption of Microwaves in Low Intensity Eucalyptus Litter Fire
(Scientific Research Publishing Inc., http://www.scirp.org, 2015)
A fuel bed was constructed where various vegetation species could be used as combustion fuel. The fuel bed was equipped with a thermocouple to measure fire temperature and a two-port automatic network analyser to measure ...
Controlled Texturing of Aluminum Sheet for Solar Energy Applications
(Scientific Research Publishing Inc., http://www.scirp.org/, 2015)
Aluminum sheets were polished to reduce ruggedness and then textured in varying acid-ethanol concentration etchant to form pores. The textured surface was characterized structurally by using X-ray diffraction (XRD) which ...
Communication: Remarkable electrophilicity of the oxalic acid monomer: An anion photoelectron spectroscopy and theoretical study
(AIP Publishing LLC., https://aip.scitation.org/journal/jcp, 2014-06-14)
Our experimental and computational results demonstrate an unusual electrophilicity of oxalic acid, the simplest dicarboxylic acid. The monomer is characterized by an adiabatic electron affinity and electron vertical ...
A new method of quantifying aerosol concentrations in atmosphere
(Springer Nature Switzerland AG. Part of Springer Nature, https://www.springer.com/journal/703, 2014-04)
Africa is one of the sources of biomass burning emissions. It is estimated that about 6 million tons of fuel per day is consumed in the southern hemisphere. Biomass burning has an important contribution on aerosol particle ...
Nondestructive measurement of momentum transfer collision frequency for low temperature combustion plasma
(Hindawi Publishing Corporation, https://www.hindawi.com/journals/ijap/, 2014)
Accurately measured momentum transfer collision frequency and electron density for fire plasma enable correct simulation of electromagnetic wave propagation in the medium. The simulation is essential for designing ...
Radio wave propagation experiment in sugarcane fire environments
(Scientific Research Publishing Inc., https://www.scirp.org/journal/jemaa/, 2016-07-21)
Large fires have an effect of suppressing Very or Ultra High Frequency (VHF/UHF) radio wave signals strength which consequently impact negatively on the efficiency of radio communications at the frequency ranges. Mobile ...
Transboundary pollution in the Capital City of Botswana
(Infogain Publication, https://ijeab.com/, 2016-09)
This paper presents aerosol studies carried out in the capital city of Botswana. The use of backward air mass trajectories has shown that elevated concentrations of fine particles correspond to situations when the air mass ...
Natural pigments as photosensitizers for dye-sensitized solar cells with TiO2 thin films
(Gazi University, https://www.ijrer.org/ijrer/index.php/ijrer, 2015)
Dye-sensitized solar cells (DSSCs) were fabricated using four natural dyes extracted from the leaves of lemon (Citrus limon) and morula (Sclerocarya birrea) and flowers of bougainvillea (Bougainvillea glabra). Optical ...
