Biosynthesis of silver nanoparticles with potent antimicrobial activity using lactic acid bacteria
(Society for Advance Healthcare Research, http://www.ejbps.com/, 2019-03)
In this study, Lactic Acid Bacteria isolated from traditional fermented foods were screened for the synthesis of silver nanoparticles. Antimicrobial activity of the synthesized nanoparticles was assayed against several ...
Assessment of the concentration of heavy metals associated with landfill leachate in Gamodubu soils in the Kweneng District, Botswana
(International Scholars Journals, http://internationalscholarsjournals.org/journal/ajss/home, 2019-01)
Composting is a common method of household waste in developing countries such as Botswana. However,
compost can introduce heavy metals which are harmful to the environment. High concentrations of heavy
metals are toxic ...
Characterization of soils in the Gamodubu landfill area in the Kweneng District, Botswana
(International Scholars Journals, http://internationalscholarsjournals.org/journal/ajss/home, 2019-01)
Understanding soil attributes guides arable farming initiatives in many countries, especially developing countries. In this study, soils of the Gamodubu area, in the Kweneng District, Botswana, were analysed to determine ...
A unified approach to integration theory
(International Journal of Applied Physics and Mathematics, www.ijapm.org/, 2019-01)
We investigate the common features and the resemblance of the central parts of the different existing integration theories to obtain a more unified approach to the notion of integral. Our approach gives a presentation of ...
Investigating the applicability of nexus thinking to private protected areas; the case of Mokolodi Nature Reverse, Southeast Botswana
(University of Botswana, www.ub.bw, 2019-09)
World-wide, Community Based Natural Resources Management (CBNRM) has gained international attention for reconciling common pool resource management with needs and aspirations of the local people. Regionally, Zimbabwe’s ...
An empirical relation for vegetation fuel flames breakdown electric field strength
(Scientific Research Publishing Inc., https://www.scirp.org/journal/jemaa/, 2019)
The compulsion to provide reliable electric power for sustenance of socio-economic development is vital for most of southern Africa states. The demand for the resource in the region is anticipated to escalate in the next ...
Optical transition rates in a cylindrical quantum wire with an inverse parabolic potential
(Opast Group LLC, https://www.opastpublishers.com/journal/advances-in-theoretical-computational-physics, 2019-05-25)
Electron transition rates due to interaction with circularly polarized light incident along the axis of a free-standing solid cylindrical nanowire are evaluated in the dipole approximation. In this case, the allowed optical ...
Diamagnetic susceptibility and optical properties of a spherical quantum dot: effects of the parabolic and the shifted parabolic potentials
(Springer Science+Business Media, LLC, part of Springer Nature, https://www.springer.com/journal/11082, 2019-06-22)
Centred charge donor related diamagnetic susceptibility and optical properties of a spherical GaAs quantum dot are presented. In particular, effects of intrinsic parabolic and shifted parabolic potentials on these quantities ...
Effect of an inverse parabolic confining electric potential on third harmonic generation in cylindrical quantum wires
(EnPress Publisher, LLC, https://systems.enpress-publisher.com, 2019)
A theoretical investigation of the effect of an inverse parabolic potential on third harmonic generation in cylindrical quantum wires is presented. The wave functions are obtained as solutions to Schrödinger equation solved ...
Optical properties of GaAs nanowires with an electric potential that varies inversely with the square of the radial distance
(Hindawi, https://www.hindawi.com/, 2019-07-10)
A theoretical investigation of optical properties of a cylindrical quantum wire (CQW) is presented. The properties studied were optical absorption coefficient (AC) and change in refractive index (CRI) of the quantum wire. ...
