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 ...
Electron states in a sinusoidally deformed cylindrical quantum wire
(Springer Nature Switzerland AG. Part of Springer Nature, https://link.springer.com/journal/40094, 2017)
Electron states in a sinusoidally deformed cylindrical nanowire are probed within the effective mass approximation. The nanowire is immersed in a homogeneous magnetic field applied parallel to the axis of the wire. The ...
Measurement of breakdown electric field strength for vegetation and hydrocarbon flames
(Scientific Research Publishing Inc., https://www.scirp.org/, 2018)
A significant number of fire-induced power disruptions are observed in several countries every year. The faults are normally phase-to-phase short circuiting or conductor-to-ground discharges at mid-span region of the ...
Geophysical and hydrogeological groundwater prospectivity mapping in the Kraaipan Granite-Greenstone Terrain, Southeast Botswana
(Scientific Research Publishing Inc., https://www.scirp.org/journal/jwarp/, 2017-10)
Application of regional geophysical methods for hydrogeological purposes has increased over the last two decades especially in arid and semi-arid areas. A project to map the Kraaipan granite-greenstone terrain in southeast ...
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 ...
Analysis of temperature data over semi-arid Botswana: trends and break points
(Springer Nature Switzerland AG. Part of Springer Nature., https://www.springer.com/journal/703, 2018)
Climate change is a global challenge which impacts negatively on sustainable rural livelihoods, public health and economic development, more especially for communities in Southern Africa. Assessment of indices that signify ...
Status of air pollution in Botswana and significance to air quality and human health
(Pure Earth (formerly Blacksmith Institute), www.pureearth.org, 2017-09-01)
Background. Air pollution is an important issue in developed and industrialized countries. The most common sources of air pollution are anthropogenic activities such as construction dust, vehicular emissions and mining. ...
