Potential for domestication and commercialization of Hoodia and Opuntia species in Botswana.
(Academic Journals, 2008-05-02)The species Hoodia (Apocynaceae) and Opuntia (prickly pear) (Cactaceae) are highly efficient in water use and belong to the Crassulacean Acid Metabolism (CAM) group of plants. These plant species are quite abundant in ... -
Preliminary investigation of transfer of metals from soil to vegetables: Case study of Spinacia oleracea L.
(Academic Journals, 2016-09)The objective of the study was to measure concentrations of Cu, Ni and Zn in Spinacia oleracea cultivated at a site near the copper and nickel mine in Selebi Phikwe. The mean concentrations (in dry matter-basis) of Cu, Zn ... -
Quadratic sequences in Pythagorean triples
(American Institute of Physics, 2022-06-16)Using the Euclid's formula, we obtain an alternative formula for generating Pythagorean triples, both primitive and non-primitive. It easy to classify Pythagorean triples using this formula based on the divisibility of the ... -
Responses of leaf parameters of Arabidopsis thaliana ecotypes to change in CO2 concentrations.
(Botswana University of Agriculture and Natural resources, 2013)An increase in anthropogenic generation of carbon dioxide (CO2) is one of the characteristic features of global climate change. How plants respond to this change has critical implications for the performance of both natural ... -
Seed dispersal by serrated tortoises (Psammobates Oculiferus) and the effect of their gut passage on seed germination.
(Researchgate, 2014-10-27)Some tortoises are frugivores and can disperse seeds away from the parent plant to areas favourable for their establishments through gut passage. We investigated the plant species dispersed by the serrated tortoise ... -
Significance of antiviral therapy and CTL-mediated immune response in containing hepatitis B and C virus infection.
(Elsevier B. V., 2021-01-12)Viral infections remain a major cause of deaths globally. Here, we focus on Hepatitis B and C viruses (HBV and HCV) infection dynamics in the liver and blood cells, taking into account non-cytotoxic and cytotoxic mediated ... -
Smallholder agriculture in African dryland agroecosystems has limited impact on trophic group composition, but affects arthropod provision of ecosystem services.
(Elsevier B.V., 2024-04-01)Agricultural intensification is a major driver of biodiversity loss, but the majority of studies highlighting these threats come from industrialised agriculture in temperate countries of the global North. However, more ... -
Substitution kinetics of platinum N,N,N’,N’-Tetrakis (2-pyridyl methyl) octane diamine aqua complex with thiourea, glutathione and L-cysteine nucleophiles
(Al-Kindi Center for Research and Development, 2020)The ligand substitution kinetics of the platinum(II) complex, [Pt2(L)(OH2)2](ClO4)4 (L = N, N,N’,N’- tetrakis (2-pyridylmethyl) octane diamine) by a series of nucleophiles, viz. thiourea (TU), L-cystein (LCYST), and ... -
Unit groups of cube radical zero commutative completely primary finite rings
(Hindawi Publishing Corporation, 2005-07)A completely primary finite ring is a ring R with identity 1 = 0 whose subset of all its zero divisors forms the unique maximal ideal J. Let R be a commutative completely primary finite ring with the unique maximal ideal ... -
Unlocking the potential of smallholder dairy farm: Evidence from the central highland of Ethiopia.
(Elsevier, 2022-12-01)Sustainable livestock farming practices have the potential to improve productivity and high income, reduce greenhouse gases, and improve household food security. Despite previous efforts to disseminate these technologies, ... -
The Use of Ethnoveterinary Medicine in Goats in Lentsweletau Village in Kweneng District of Botswana.
(Researchgate, 2013-07-28)The study was conducted to document the use of ethnoveterinary medicine in goats in Lentsweletau village in Kweneng district of Botswana. Structured questionnaires were used to collect information from 30 goat owners. The ... -
Using Technology Acceptance Model to Predict Lecturers’ Acceptance of Moodle: Case of Botswana University of Agriculture and Natural Resources
(Infonomics Society, 2019-03-01)The use of technology to enhance learning is regarded as significant among educational institutions due to continuous improvements of the Internet and other communication technologies. The Botswana University of Agriculture ... -
A vaccination model for COVID-19 in Gauteng, South Africa
(KeAi Communications Co., 2022-09)The COVID-19 pandemic provides an opportunity to explore the impact of government mandates on movement restrictions and non-pharmaceutical interventions on a novel infection, and we investigate these strategies in early-stage ... -
Wet deposition of 210Pb aerosols over two areas of contrasting topography
(Institute Of Physics Publishing Ltd, 2006-11-24)Deposition fluxes of 210Pb on low and moderately high-elevation sites of Edinburgh (Scotland) and mid-Wales, respectively, have been measured. The excess 210Pb fluxes in moorland Edinburgh soils did not vary significantly ... -
Wildfires in Botswana and Their Frequency of Occurrence
(Scientific Research Publishing, 2021-09-13)Fires play an essential part in the maintenance of the environment, but am- plified fire activity often leads to adverse effects in the environment such as destruction of property and loss of life. Botswana has experienced ...
