Author:Mostert, FJ; Olivier, MariusDate:Oct 2011It is well known that an intense flash of light is emitted when an explosive charge is detonated. The light emission continues well beyond the actual detonation process due to shock excitation of the air molecules around the charge, as well ...Read more
Author:Popp, A; Lück-Vogel, Melanie; Blaum, N; Jeltsch, FDate:Nov 2009In this study, the authors present a stochastic landscape modeling approach that has the power to transfer and integrate existing information on vegetation dynamics and hydrological processes from the small scale to the landscape scale. To ...Read more
Author:Aramide, B; Jamiru, T; Pityana, Sisa L; Sadiku, R; Popoola, PDate:Apr 2022The poor tribological property and the high susceptibility of steel material used in mining and tillage tools to wear and corrosion attack during mining and tillage operations have brought about the need to enhance its property. Hence, this ...Read more
