Optimization of the physicochemical parameters of selected agricultural wastes to increase biosynthetic gas and biochar yields
(Kyambogo University (unpublished work), 2019-10)Biosynthetic gas and biochar are gaseous and solid fuels, respectively, that can be produced from various lignocellulosic feedstock via pyrolysis and are recognized as clean and attractive sources of renewable energy. They ... -
Catalytic potential of natural zeolites and selected metalic ores in pyrolysis of groundnut shells for bio-oil production
(Kyambogo University (un published work), 2019-07)Catalytic pyrolysis is a promising thermochemical method of conversion of biomass to chemicals and fuels compatible with current petrochemical engines. Catalytic modification of pyrolyzed bio-oils are geared towards the ... -
The fatty acid composition of edible grasshopper Ruspolia differens (Serville) (Orthoptera: Tettigoniidae) feeding on diversifying diets of host plants
(Wiley online Library: Entomological Research, 2018-12-12)Ruspolia differens (Serville) (Orthoptera: Tettigoniidae) is a highly valued edible grasshopper species in Africa. However, the effects of plant diets on lipid content and fatty acid composition of R. differens are not ... -
Microbial and heavy metal contamination in herbal medicines in Uganda
(Kyambogo University, 2019-10)The use of herbal medicines in various countries has been on the increase over the years for primary health care since they are cheap and easily accessible. However, herbal medicines present safety concerns which are ... -
Fatty acids, heavy metal concentration, and characteristics of selected oil seeds grown in west Nile, Uganda
(Kyambogo University, 2021-03)In this study vegetable oils extracted from three types of oil seeds namely; sunflower (helianthus annus), sesame (sesamum indicum) and peanut (Arachis Hypogaea) grown in west nile sub-region were investigated. Fatty acid ... -
Electrodeposition of nickel-metalloid alloy films and their investigation for electrocatalytic water splitting
(Kyambogo University, 2021-03)Electrocatalytic splitting of the water molecule to produce hydrogen as an energy carrier provides a very promising pathway for provision of green and inexhaustible renewable energy for the future. The bottleneck of this ... -
Pesticide residues and heavy metals in lake Victoria nile perch, lates niloticus, belly flap oil
(Springer Link: Bulletin of Environmental Contamination and Toxicology., 2009-03-05)Oil was extracted from the belly flaps of varied sizes of Nile perch caught from Lake Victoria (Uganda). The oil was analyzed for pesticide residues and heavy metals. Total residual concentration of dichlorodiphenyltrich ... -
Fatty acid profile and stability of oil from the belly flaps of Nile perch (Lates niloticus)
(Elsevier: Food Chemistry., 2008-05-01)Oil extracted from the belly flaps of Lake Victoria Nile perch (Lates niloticus) was evaluated for fatty acid composition, contents of vitamin A, β-carotene and α-tocopherol, and oxidative stability. The oil was found to ... -
