Shoot allometry of Jatropha curcas
Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science • Authors: SB Ghezehei --- Department of Plant Production and Soil Science, South Africa JG Annandale --- Department of Plant Production and Soil Science, South Africa CS Everson --- Department of Plant Production and Soil Science, South AfricaThe South African government has banned planting of Jatropha curcas L. (Jatropha), potentially a multipurpose tree and biofuel source, owing to insufficient knowledge about the species. Use of allometry as a non-destructive method of monitoring growth and biomass attributes of... -
Experiences with Jatropha cultivation in sub-Saharan Africa: Lessons for the next phase of development
Item type: Journal Article • Journal: African Journal of Science, Technology, Innovation and Development • Authors: Raphael M. Jingura --- Directorate of Quality Assurance and Graduate Studies, Zimbabwe Reckson Kamusoko --- Directorate of Quality Assurance and Graduate Studies, ZimbabweJatropha curcas L. has emerged in recent times as a leading energy crop in sub-Saharan Africa with over 32 countries in the region involved in its production. The establishment of Jatropha has not been without challenges and has arguably been... -
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... -
Carbon stocks of the terraces of the Lower Tana River floodplain and delta, Kenya, prior to conversion for biofuel production
Item type: Journal Article • Journal: African Journal of Aquatic Science • Authors: LV Mukhwana --- Kenya Wetlands Biodiversity Research Team (KENWEB), Kenya Q Luke --- Kenya Wetlands Biodiversity Research Team (KENWEB), Kenya E Delmas --- Kenya Wetlands Biodiversity Research Team (KENWEB), Kenya K Otoi --- Kenya Wetlands Biodiversity Research Team (KENWEB), Kenya O Hamerlynck --- Kenya Wetlands Biodiversity Research Team (KENWEB), Kenya L Vandepitte --- Flanders Marine Institute (VLIZ), Belgium B Adkins --- Dadacha Consulting Ltd, KenyaFew studies have addressed the terraces adjacent to the Tana River and delta. In May 2012 a survey assessed the woody vegetation of the terraces in anticipation of their conversion to a biofuel farm. The 64 000 hectares targeted by... -
Thermal stability of a vegetable oil-based thermal fluid at high temperature
Item type: Journal Article • Journal: African Journal of Science, Technology, Innovation and Development • Authors: Aboubakar Gomna --- Laboratoire Énergies Renouvelables et Efficacité Énergétique (LabEREE), Burkina Faso Kokouvi Edem N’Tsoukpoe --- Laboratoire Énergies Renouvelables et Efficacité Énergétique (LabEREE), Burkina Faso Nolwenn Le Pierrès --- LOCIE, France Yézouma Coulibaly --- Laboratoire Énergies Renouvelables et Efficacité Énergétique (LabEREE), Burkina FasoSynthetic and mineral oils are widely used in high temperature processes (above 200°C) as heat transfer fluids or thermal storage materials. Mineral oils are essentially derived from petroleum that is depleting and synthetic oils are expensive. Furthermore, these oils are... -
Technico-economic comparison of heat transfer fluids or thermal energy storage materials: A case study using Jatropha curcas oil
Item type: Journal Article • Journal: African Journal of Science, Technology, Innovation and Development • Authors: Kokouvi Edem N’Tsoukpoe --- , Burkina Faso Nolwenn Le Pierrès --- , France Yao Manu Seshie --- , Burkina Faso Yézouma Coulibaly --- , Burkina FasoThermal oils are omnipresent in processes using heat at high temperature as heat transfer fluids (HTFs) as well as thermal storage materials (TESMs), particularly in concentrating solar plants. In this study, a methodology for technico-economic comparison of HTF and TESM...
