ABSTRACT Solar cells based on ITO/InP have been shown to possess a remarkable potential for space applications. The determination of the terrestrial and simulated-space stability of any type of solar cell is important in obtaining the payload power requirements of a spacecraft which will be powered by that type of cell. In this work, a preliminary investigation of the terrestrial stability of ITO/InP cells has been performed. The cells were stored in the dark for six months in thermostaticall...
Abstract Co-digestion of various wastes and biomass feedstock has been shown to improve the digestibility of the materials and biogas yield. In this study, the co-digestion of water hyacinth and fish waste was studied at different mixing proportions. The anaerobic digestion was carried out in batch digester reactors sized 500 ml and were charged to 10 % of total vol-ume. Co-digestion was conducted for a retention period of 21 days in mesophilic temperature ranging 25.3 °C to 33.4 °C. The re...
