Plant alkali content and radio wave communication efficiency in high intensity savanna wildfires
(Elsevier Science Ltd. www.elsevier.com/locate/jastp, 2007)
The flames of wildfires are weakly ionized gas. The ionization is mainly due to omnipresent alkali and alkaline earth
metal species that are emitted from thermally decomposing plant structure into the flame during a ...
Photon interaction cross sections in the low energy region in Mg and V
(Elsevier Science Ltd. www.elsevier.com/locate/radphyschem, 2004)
The interaction of photons with matter has been
extensively studied over the past several decades in view
of its importance in basic radiation physics research,
medical, industrial and other applied fields. Large
amounts ...
South African seismicity, April 1997 to April 1999, and regional variations in the crust and uppermost mantle of the Kaapvaal craton
(Elsevier Science Ltd. www.elsevier.com/locate/lithos, 2003)
Events induced by deep gold-mining activity on the edge of the Witwatersrand basin dominate the seismicity of South
Africa. The deployment of 54 broad-band seismic stations at 84 separate locations across southern Africa ...
Stochastic models for sunshine duration and solar irradiation
(Elsevier Science Ltd: http://www.elsevier.com/wps/find/journaldescription.cws_home/969/description#description, 2002)
Abstract
Harmonic analysis of sunshine duration and solar irradiation measured at Sebele, Botswana is carried out. The data used consists of the monthly averages and the Julian-days averages of sunshine duration and solar ...
Type II superconducting disk in a spatially inhomogeneous applied magnetic field
(Elsevier Science Ltd. www.elsevier.com/locate/physc, 2003-01)
The problem of a type II superconducting disk in a spatially inhomogeneous magnetic field is considered. The aim
of the investigations undertaken here is to evaluate the effects of the spatial inhomogeneity of the parallel ...
The influence of the Tbetta level upon fluorescence and laser properties of aromatic compounds
(Elsevier Science Ltd. www.elsevier.com/locate/saa, 2004)
The fluorescence and laser properties of seven specially chosen aromatic compounds are studied at 293 ◦C. The quantum yield of fluorescence,
γ, decay times, τf , of the deaerated and non-deaerated solutions are measured. ...
Gravity anomaly patterns in the south-central Zimbabwe Archaean craton and their geological interpretation
(Elsevier Science Ltd. www.elsevier.com/locate/jafrearsci, 2008)
The granite-greenstone terrain of south-central Zimbabwe, encompassing the Belingwe (Mberengwa) greenstone belt and sections of
the Great Dyke, provides important constraints on models for the evolution of the Zimbabwe ...
Phase segregation in Pb:GeSbTe chalcogenide system
(EDP Sciences. http://www.epjap.org/, 2008)
Effect of Pb substitution on the amorphous-crystalline transformation temperature, optical band
gap and crystalline structure of Ge2Sb2Te5 has been studied. In Pb:GeSbTe chalcogenide films prepared by
thermal evaporation, ...
Contact charging of solution-cast polymers by metals
(Elsevier Science Ltd. www.elsevier.com/locate/elstat, 2005)
The charge transfer between metals and some solution-cast polymers has been investigated
by employing intermittent soft contact under a controlled condition. The result of our
measurements reveals that the measured charge ...
Fluorescence and laser properties of D2-, C2- and D3 symmetry series oligophenylenes
