Effects of combined apertures on the magnitudes of electric coupling coefficients of combline resonators
(IOP Publishing, 2014)
The effects of differently positioned and combined apertures on the magnitudes of electric coupling coefficients of two identical combline resonators are analysed. Coupling coefficient, k-vertical symmetry provides greater ...
Application of high resolution NMR, FTIR, and GC–MS to a comparative study of some indigenous seed oils from Botswana.
(Elsevier, 2017-12)
Spectroscopic techniques utilizing FTIR, 1H and 13C NMR spectral fingerprints of the neat oils, as well as
standard titrimetric and GC–MS analyses were all employed to determine the quality parameters and fatty acid
(FA) ...
Effects of pre-treatments methods on the germination of pod mahogany (afzelia quanzensis)and mukusi(baikiaea plurijuga)seeds
(International Journal of Innovative Research in Science, Engineering and Technology, 2014-01)
Seed pre-treatments (mechanical, concentrated sulphuric acid for 3, 6, 9 and 12 minutes, hot water treatments for 3, 6, 9 and 12 minutes) were carried out to overcome seed dormancy of Afzelia quanzensis and Baikiaea plurijuga ...
Rheology and botanical origin of Ethiopian monofloral honey
(Elsevier, 2016-09-20)
Rheology and botanical origin of Ethiopian monofloral honeys were investigated using harmonized method of melissopalynology and HAAKE VT 500 over a temperature range of 25–45 °C, respectively. The percent dominance of ...
Validation and Reproducibility of a Food Frequency Questionnaire for use among Adults in Botswana.
(Cambridge University Press, 2012-11-01)
Objective: To evaluate the validity and reproducibility of a 122-item interviewer-administered quantitative FFQ developed to determine food and nutrient intakes of adults in Botswana.
Design: Relative validity of the FFQ ...
Symbiotic functioning and bradyrhizobial biodiversity of cowpea (Vigna unguiculataL. Walp.) in Africa
(SpringerLink, 2010-03-23)
Cowpea is the most important food grain legume in Sub-Saharan Africa. However, no study has so far assessed rhizobial biodiversity and/or nodule functioning in relation to strain IGS types at the continent level. In this ...
Sorghum yield and associated satellite-derived meteorological parameters in semi-arid Botswana
(African Crop Science Journal, 2015-03-15)
Africa has sparse meteorological stations, hence it is increasingly common to use satellite-derived meteorological parameters, where in-situ measuremnts are not available. The objective of this study was to determine if ...
Documentation of indigenous knowledge and best-bet practices on the use of animals and plants for sustainable natural resources management in Botswana
(Botswana University of Agriculture and Natural Resources, 2014)
A study was carried out to document indigenous knowledge (IK) and practice on use of animals and plants, and best-bet practices (BBPs) during Phase I (2003-2004) of the Desert Margins Programme (DMP), whose overall objective ...
Demographic parameters of cowpea aphid Aphis craccivora (Homoptera: Aphididae) on different Botswana cowpea landraces
(Cambridge University Press, 2012-12-01)
The variation in demographic parameters (namely survival and fecundity, intrinsic rate of natural increase pre-reproductive period and relative growth rate) was used to assess the resistance of cowpea landraces (namely ...
Grazing management systems and their effects on savanna ecosystem dynamics: A review
(Academic Journals, 2013-06)
The savanna ecosystems support livestock production and livelihood of pastoral communities. The degradation of savanna ecosystems due to overgrazing had lead government commercializing communal grazing land to privately ...
