Effect of brining on the drying rate of tilapia in a solar tunnel dryer

Kituu, G. M.; Shitanda, Douglas; Kanali, C. L.; Mailutha, J. T. (2008-07)

In addition to being a source of protein, fish is an important source of local and foreign currency earnings in Kenya. A substantial amount of fish production is exported. Approximately 30 per cent is exported to the ...
The potential of chainsaw frame mills in on-farm timber processing in Kenya

Muthike, G. M.; Shitanda, Douglas; Kanali, C. L.; Muisu, F. N. (Kenya Forestry Research Institute, 2009)

Chain saws have been used to convert on-farm trees into timber over a long time in Kenya. Large saw path, especially due to the back and forth mode of operation remains a major contributor to low timber recovery and surface ...
Characterization of Kenyan grown Mondia Whytei roots and their potential uses

Shitanda, Douglas; Mukonyi, K.; Simiyu, L.; Mayunzu, O.; Shanda, R. (Asian Association for Agricultural Engineering, 2007)

The Mondia Whytei roots inner core dimension and the whole root dimensions were determined and recorded. The length of roots selected was 100 mm for ease of measurement. It was observed that the length of the roots before ...
Experimental use of Arduino-based accelerometers for assessment of train induced soil vibration characteristics

Kioko, Paul C. K.; Abuodha, Silvester O.; Mwero, John N.; Njuguna, Kuri Z. (2023-11)
