Modeling salmonellosis transmission dynamics in humans and dairy cattle with optimal controls.
(Elsevier Inc., 2025-02)In this paper, we develop a mathematical model to examine the transmission dynamics and control analysis of salmonellosis in humans and dairy cattle. The model considers three time-dependent controls (improving hygiene, ... -
Dynamical modeling of Salmonellosis in humans and dairy cattle with temperature and pH effects.
(Elsevier B.V., 2024-12-20)Approximately 20 million cases and 0.15 million human fatalities worldwide each year are caused by Salmonellosis. A mechanistic compartmental model based on ordinary differential equations is proposed to evaluate the effects ... -
Gender Disparities and Board Representation in Zimbabwe.
(Econjournals, 2024-12-06)Approximately one-third of the world’s GDP is held by the 500 biggest firms worldwide. Nonetheless, barely 25% of Fortune 500 board members and <6.7% of board chairs worldwide were female in 2021. The aim of this paper is ... -
Poor academic performance of students in agriculture at primary schools in Botswana: Analysis of causes and ways to improve.
(Society for Research and Knowledge Management, 2021-09)This quantitative study analysed the factors that cause poor performance and identified the possible ways to improve the performance of students in agriculture at primary schools in Botswana. Data was collected using a ... -
Comparative effects of Bioslurry and chemical fertilizer on soil properties and performance of Spider plant (Cleome gynandra L).
(Buan, 2024-09)Spider plant (Cleome gynandra L.) is a promising indigenous leafy vegetable in the diet of many African rural populations. However, soil fertility for production of spider plant remains an unexploited area leading to low ... -
Comparison between the United States Soil Conservation Service (SCS) and the two models commonly used for estimating rainfall-runoff in south-eastern Botswana
(Water SA, 2007-12-06)The United States Soil Conservation Service (SCS) curve number method is used to estimate rainfall runoff from three sub-watersheds in South-Eastern Botswana. This approach uses the NASA Endeavour Shuttle Radar Topography ... -
Development of the Agricultural and Biosystems Engineering Programme at the Botswana University of Agriculture and Natural Resources (BUAN)
(CRC Press, 2024)This chapter discusses the agricultural and biosystems engineering (ABEN) programme at the Botswana University of Agriculture and Natural Resources (BUAN). It covers the progression from the initial engineering courses, ... -
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 ... -
Rainfall reliability, drought and flood vulnerability in Botswana
(Water SA, 2004-08-04)Rainfall data from 14 stations (cities, towns and major villages) spanning 26 years (1970 to 1995) were used to calculate reliability and vulnerability of rainfall in Botswana. Time series data for 72 years were generated ... -
Non-seasonal Landsat based bare area gain detection in Botswana during 2002 to 2020 Period using Maximum Likelihood Classifier (MLC).
(South African Journal of Geomatics, 2022-09-04)This paper estimates bare area gain detected using cloud free Landsat 7 (ETM+) and Landsat 8 (OLI) in Botswana. From 2002 to 2020, agricultural fields shrunk by 76.4%, while built-up increased by 49.2%, and bare areas ... -
Spatial and temporal variation of soil properties and soil organic carbon in semi-arid areas of Sub-Sahara Africa
(Elservier, 2024-03)Land cover land use (LCLU) patterns play a crucial role in shaping the biosphere and global climate. This influence is especially pronounced in arid and semi-arid regions, where environmental vulnerabilities are heightened. ... -
Agricultural Drainage Water Assessment for Possible Reuse: A Case Study from Pandamatenga Commercial Arable Farms in Botswana
(International Journal For Multidisciplinary Research, 2023-09-10)This study set out to assess the quality of water in the drainage channel located in the northern plain of the Pandamatenga Commercial Arable farms in Botswana for possible agricultural reuse. This was achieved by analysing ... -
Culicoides associated with dairy cows at Sebele, Gaborone, Botswana.
(Springer, 1999-07-17)The abundance and species composition of Culicoides collected in a light trap placed next to a herd of cows in Sebele are reported. It is the 1st report on the collection and identification of Culicoides with dairy cows ... -
Safflower Growth, Development, Yield and Oil Content as Influenced By Genotype and Environment Interaction Under Onfarm Conditions
(Botswana University of Agriculture & Natural Resources, 2024-09)Safflower (Carthamus tinctorius L.) is amongst the neglected and underutilized oilseed crop that is adaptable to environmental conditions present in arid and semi-arid lands (ASALs). It has many uses like foods, textile, ... -
Assessing accumulation (growth and internal mobility) of Salmonella Typhimurium LT2 in fresh-cut cantaloupe (Cucumis melo L.) for optimization of decontamination strategies
(Elservier, 2023-08)Fresh cantaloupe flesh has intercellular spaces, which may be the route for internalization of gram-negative bacteria. Growth of Salmonella Typhimurium LT2 was described by the Baranyi growth model, while and exponential ... -
Application of a sex identification technique in juvenile ostriches and its potential application in Botswana
(South African Journal of Animal Science, 2002-09-22)Sexing ostrich chicks and juveniles before the dimorphous appearance of the plumage that starts at 14 months of age is proving difficult and cumbersome for Botswana farmers. This problem delays early selection of birds for ... -
An Econometric Analysis of Total (Domestic) and Import Demand for Beef in Hong Kong
(Taylor and Francis, 2008-10-18)This paper presents an applied econometric analysis of total (domestic and import) demand for beef in Hong Kong for the period 1970 to 1988. The estimates are in logarithmic form and provide elasticity estimates for beef ... -
African Yam Bean: An Under-Utilized Legume with Potential as a Tuber and Pulse Crop
(Taylor and Francis, 2008-09-22)African Yam Bean (Sphenostylis stenocarpa) is a legume that provides nutritionally rich seeds, tubers and leaves for human consumption. Production relies upon the cultivation of landraces and, to some extent, the collection ... -
