Analyzing sustainable energy in developing countries: Selected South African case studies by Howells, Mark Idwal

“…In an appendix it develops an efficient industrial data collection process using an MCDA analysis. The main theme of this thesis is to show how suitable modelling can not only warn of inefficiency in development policies, but also indicate technical scenarios of how such inefficiencies are best remedied. …”

Experimental evaluation of the effect of thermal heat and pressure pre-treatment on primary sludge anaerobic digestion by Mwidu, Aaron

“…The percentage of Chemical Oxygen Demand (COD) removal for D1 ranged from 17% a to 54%, while that of D2 ranged from 16% to 62% for 8 to 30 day SRT respectively, gas production per liter influent for D1 ranged from 1.94 liter gas/liter influent to 19.08 liter gas/liter influent while that for D2 ranged from 1.81 liter gas/liter influent to 20.01 liter gas/liter influent, methane gas composition for both D1 and D2 remains the same for all the sludge ages varying between 50%-69% for methane and 34% to 45% for carbon dioxide. …”

Seasonal characteristics of phytoplankton bloom phenology in the northern Benguela Upwelling System by Matlakala, Mmakabele Lebogang

“…This study uses historical long-term in situ data (at 10 and 70 NM stations) as well as OC-CCI satellite ocean colour data to investigate seasonal phytoplankton bloom phenology and community structure of diatoms, dinoflagellates and coccolithophores in the northern BUS. …”
