Antioxidant and antidiabetic potential of Myrothamnus flabellifolius found in Botswana
(Cogent OA, https://www.cogentoa.com/journal/biology, 2016-12-29)
The total phenol content, antioxidant and antidiabetic activity of Myrothamnus flabellifolius (MF) were investigated. The study revealed 70% ethanol/water (EW70), 70% methanol/water (MW70) and methanol (Me) extracts to ...
Some relations between admissible monomials for the polynomial algebra
(Hindawi Publishing Corporation, www.Hindawi.com, 2015)
Let P(𝑛) = F2[𝑥1, . . . , 𝑥𝑛] be the polynomial algebra in 𝑛 variables 𝑥𝑖, of degree one, over the field F2 of two elements. The mod-2 Steenrod algebra A acts on P(𝑛) according to well known rules. A major problem ...
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 ...
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. ...
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 ...
Electrophilicity of oxalic acid monomer is enhanced in the dimer by intermolecular proton transfer
(Royal Society of Chemistry, https://pubs.rsc.org/en/journals/journalissues/cp#!recentarticles&adv, 2017)
We have analyzed the effect of excess electron attachment on the network of hydrogen bonds in the oxalic acid dimer (OA)2. The most stable anionic structures may be viewed as complexes of a neutral hydrogenated moiety HOA˙ ...
