Abstract The study on the effect of particles size on biogas production has been conducted. Substrates consisted of pre-treated water hyacinth with drying and grounded to fine particles of (0.001and 0.05 mm) and chopped water hyacinth to small particles of (1.0 and 2.5 mm). The reactor digesters were operated at mesophilic temperature ranges of 25 °C to 32 °C with retention time of 23 days. Results showed that highest biogas production occurred with the most finely grounded substrate (0.00...
ABSTRACT There are two viruses found to be direct aetiological agents of leukaemia, namely Epstein-Barr virus (EBV) and Human T-cell leukaemia virus. Viral infections were estimated to cause 15 – 20 % of all human cancers, by its capability to release virus-encoded proteins into its host. These proteins reprogram host cell signalling pathways within deoxyribonucleic acid (DNA), which are responsible for differentiation and proliferation.
