(Journal of Agricultural Science and Technology, 2012-10-20)Quantitative determination of hydrogen cyanide (HCN) content in a toxic local cassava variety “Rutuga” with an initial total HCN of 16.65%, free HCN of 9.19% and bound HCN (cyanoglycosides) of 7.46% in the fresh peeled ... -
Jigger-Control Related Health Issues and Suggested Interventions in Iganga District, Eastern Uganda
(International Journal of Science and Research (IJSR), 2016)Jigger infestation is a neglected tropical disease caused by penetration of the sand flea into the skin of a person and other hosts. The wounds created cause pain, discomfort and may lead to secondary infections such as ... -
Heterocyphelium leucampyx (Arthoniales, Ascomycota): another orphaned mazaediate lichen finds its way home
(The Lichenologist, 2017)Heterocyphelium is a mazaediate genus containing a single species, H. leucampyx. The species was originally described from Cuba within the genus Trachylia (Arthoniales, Arthoniaceae) and later placed in various genera of ... -
Environmental Dynamics of Lake Victoria: Evidence from a 10,000 14C yr Diatom Record from Napoleon Gulf and Sango Bay
(Journal of Environmental Science and Engineering, 2016)Bio-proxies provide relevant information on ecosystem health and environmental dynamics. In this study, diatom assemblages of two cores collected from the Ugandan side of Lake Victoria at Napoleon Gulf (“NAPG1” (GPS, ... -
A Mathematical Model of Solid Waste Accumulation and Treatment with a Varying Human Population Size
(Biomath Communications, 2022)Solid waste management has continued to be an increasing challenge worldwide and the situation has become worse in urban areas of developing countries. The rapid urban population growth, mainly due to high immigration and ... -
Decades of quaternary research in Eastern Africa: Implications for sustainable future
(2020)The 5th East African Quaternary Research Association (EAQUA) workshop was themed “Decades of Quaternary Research in Eastern Africa: Implications for Sustainable Future”. It was intended to foster ways of integrating the ... -
Compliance to Post-Harvest Handling Practices of Beef along the Beef Value Chain in Uganda
(Journal of Nutrition & Weight Loss, 2019-06-20)Introduction: Beef handling from slaughter to butchery if not compliant with standard operating requirements may lead to contamination by spoilage and pathogenic microorganisms originating from equipment, surfaces, personnel, ... -
Climate and Cultural Dynamics in the Great Lakes Region of Western Uganda during the Last ca. 1000 Yr. BP
(Geophysical Research Abstracts, 2018)A multi-proxy analysis of microfossils from sedimentary records, together with evidence from historical and archaeological data, provide evidence of climatic and cultural changes in great lakes region of western Uganda for ... -
Can citizen scientists provide a reliable geo-hydrological hazard inventory? An analysis of biases, sensitivity and precision for the Rwenzori Mountains, Uganda
(Environmental Research Letters, 2022-03-21)Spatio-temporal inventory of natural hazards is a challenging task especially in rural or remote areas in the Global South where data collection at regional scale is difficult. Citizen science, i.e. involvement of no-experts ... -
Variations of Crest-to-Trough TEC Ratio of the East African Equatorial Anomaly Region
(International Journal of Astrophysics and Space Science 2016, 2015-03)In this paper, Vertical Total Electron Content (VTEC) data derived from dual-frequency GPS measurements obtained at two ground stations were used to study the variability of the equatorial ionization anomaly (EIA). The ... -
Validating the use of scintillation proxies to study ionospheric scintillation over the Ugandan region
(Journal of Atmospheric and Solar-Terrestrial Physics, 2015-03)In this study, we compare the standard scintillation indices (S4 and σΦ) from a SCINDA receiver with scintillation proxies (S4p and sDPR||) derived from two IGSGPS receivers. Amplitude (S4) and phase (σΦ) scintillation ... -
Trends of ionospheric irregularities over African low latitude region during quiet geomagnetic conditions
