  • Application of renewable energies for storage of horticultural produce in marginal areas of Kenya 
    Makanga, J. T.; Shitanda, Douglas; Njoroge, C.; Ong'era, M. G. (2012)
    The objective of the research were to a prototype solar-charcoal cooler and test its performance in the temperature development and products storageability. A prototype solar-charcoal cooler was developed at the ...
  • 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 ...
  • Development of an alternative binder for bagasse briquettes 
    Shitanda, Douglas; Kitheka, M. M.; Wamai, E. (2006)
  • Effect of brining on the drying rate of tilapia (Oreochromis niloticus) in a solar tunnel dryer 
    Kituu, G. M.; Shitanda, Douglas; Silayo, V.; Odote, P.; Bongyereire, J. (Inter-University Council for East Africa Lake Victoria Research Initiative, 2010)
    This study determined effect of on the drying rate of tilapia in a solar tunnel dryer. Tilapia fish was split into pieces of 4 cm by 3 cm by 9 mm and soaked into four brine concentrations varying between 0-15%. Moisture ...
  • 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 ...
  • Morphological characterization of Kenyan papaya germplasm (Carica papaya L.) 
    Asudi, G. O.; Ombwara, F. K.; Rimberia, F. K.; Nyende, A. B.; Ateka, E. M.; Wamocho, L. S.; Shitanda, Douglas; Onyango, A. (International Society for Horticultural Science (ISHS), 2009)
    Many papaya cultivars found in Kenya have not been characterized and documented. Therefore, there is difficulty in differentiating the Carica papaya cultivars in the different regions of Kenya. Characterization of papaya ...
  • 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 ...
  • Properties of Kenyan grown Mondia Whytei roots 
    Shitanda, Douglas; Mukonyi, K.; Simiyu, L.; Mayunzu, O.; Shanda, R. (Asian Association for Agricultural Engineering, 2007)
    Mondia Whytei (Asclepiadaceae) is a tropical species widely used in African countries where it is found, both at subsistence and commercial level. The species is commonly found in remaining tropical rain forests. Solar ...
  • Storage and preservation of seed grain under enhanced hermetic conditions 
    Home, P. G.; Shitanda, Douglas; Ndigithe, P. M. (Asian Association for Agricultural Engineering, 2007)
    Hermetic grain storage is a system where dry grain is stored under conditions of oxygen deficit. Any insects in the stored grain then suffocate themselves to death through depletion of any remaining oxygen and release of ...
