Evaluation of the acute toxicity of refined petroleum products against Pila ovata (Gastropoda: Ampullariidae) and Poecilia reticulata (Teleostei: Poeciliidae)
Item type: Journal Article • Journal: African Journal of Aquatic Science • Authors: BlessingJ OribhaborStatic and static-renewal evaluation of the acute toxicity of three refined petroleum products — petrol, kerosene and diesel — against two freshwater animals, the mollusc Pila ovata and the fish Poecilia reticulata, was conducted in the laboratory. Petrol, kerosene and... -
Engine performance of biodiesel-biodiesel blends at varying engine speeds
Item type: Journal Article • Journal: African Journal of Science, Technology, Innovation and Development • Authors: Godwin K. Ayetor --- Department of Automotive Engineering, Ghana Albert K. Sunnu --- Department of Mechanical Engineering, GhanaBiodiesel blends with petroleum diesel have long been experimented on and considered good alternatives to petroleum diesel. Most blends considered biodiesel percentages of 20 and less. This work considered blending B100 of separate biodiesel feedstocks to determine their influence on... -
Institutional and regulatory framework for biodiesel production: International perspectives and lessons for South Africa
Item type: Journal Article • Journal: African Journal of Science, Technology, Innovation and Development • Authors: Chipo Mukonza --- Institute of Corporate Citizenship, South Africa Godwell Nhamo --- Institute of Corporate Citizenship, South AfricaBiodiesel is produced from a range of feedstock including oil seeds (canola/rape and soya beans), as well as used cooking oil. This is done by converting the oil to methyl esters in a transesterification process that yields glycerine as one... -
Fuel properties comparison of species of microalgae and selected second-generation oil feedstocks
Item type: Journal Article • Journal: African Journal of Science, Technology, Innovation and Development • Authors: Andrew C. Eloka-Eboka --- Discipline of Mechanical Engineering, South Africa Chiemela Onunka --- Discipline of Mechanical Engineering, South AfricaComparative investigation and assessment of microalgal technology as a biodiesel production option was studied alongside other second generation feedstocks. This was carried out by comparing fuel properties of species of Chlorella vulgaris, Duneliella spp., Synechococus spp. and Senedesmus spp. with... -
Performance and emission evaluation of pure biodiesel from non-edible feedstock and waste oil in a diesel engine
Item type: Journal Article • Journal: African Journal of Science, Technology, Innovation and Development • Authors: E. I. Onuh --- Mechanical Discipline, School of Engineering, South Africa Freddie Inambao --- Mechanical Discipline, School of Engineering, South AfricaBiodiesel prepared from Jatropha, Moringa and restaurant waste oil were evaluated in a 3.5 kw diesel engine to determine their performance and pollutant emission. The brake specific (BS) emissions across the full load spectrum were benchmarked against the United States Environmental... -
The economic cost of unreliable grid power in Nigeria
Item type: Journal Article • Journal: African Journal of Science, Technology, Innovation and Development • Authors: Samuel Olowosejeje --- School of Engineering, Nigeria Paul Leahy --- School of Engineering, Republic of Ireland Alan Morrison --- Department of Electrical and Electronic Engineering, School of Engineering, Republic of IrelandThe ever-increasing demand for electrical power in Nigeria, coupled with a limited supply, have restricted the nation's socioeconomic development. The country’s policymakers, aware of this, have formulated and enacted energy development policies in recent years targeted at diversifying the current...
