  • Quantification and characterization of cocoa pod husks for electricity generation in Uganda. 
    Kilama, George; Lating, Peter O.; Byaruhanga, Joseph; Biira, Saphina (Busitema University ; BMC, 2019)
    Background: Due to limited coverage, the electricity power supply in Uganda is an obstacle to the country’s economic development. Utility firms in Uganda either lack the financial capacity to expand their grids to isolated ...
  • The role of ZrCl4 partial pressure on the growth characteristics of chemical vapour deposited ZrC layers 
    Biira, Saphina; Crousec, P. L.; Bissettd, H.; Hlatshwayoa, T. T.; Njoroge, E.G.; Neld, J. T.; Ntsoaned, T. P.; Malherbe, J.B. (Elsevier, 2017-04-21)
    ZrC layers were deposited in a chemical vapour deposition (CVD) reactor on graphite substrates using a ZrCl4- Ar-CH4-H2 precursor mixture. The deposition was conducted at different ZrCl4 partial pressures at a constant ...
  • Thermal performance evaluation of the funnel solar cooker of different funnel lengths implemented in Nagongera, Uganda. 
    Chepkurui, Jonah; Biira, Saphina (Busitema University ; Tanzania Journal of Science., 2020-01-08)
    The aim of this study was to evaluate the thermal performance of a funnel solar cooker with different funnel lengths. Four funnel solar cookers of varying funnel lengths were constructed at Nagongera, in Tororo District, ...
  • Thermodynamics kinetics of boron carbide under gamma irradiation dose. 
    Mirzayev, Matlab; Demir, Ertugrul; Mammadov, Khagani; Mehdiyeva, Ravan; Jabarov, Sakin; Tugru, A. Beril; Biira, Saphina; Tiep, Nguyen; Thabethe, Thabsile (Busitema University ; World Scientific publishing, 2019-04-11)
    In this paper, high purity boron carbide samples were irradiated by 60Co gamma radioisotope source (0.27 Gy/s dose rate) with 50, 100, 150 and 200 irradiation hours at room-temperature. The unirradiated and irradiated boron ...
  • Trends and Status of Women in Physics in Uganda. 
    D’ujanga, Florence M.; Biira, Saphina; Akoba, Rashida (Busitema University ; AIP publishing, 2019)
    Most women in Uganda with an advanced degree in physics find employment at a university, teaching and conducting research. Very few take jobs in by industry or at government research laboratories. This paper discusses the ...
  • X-ray diffraction and thermodynamics kinetics of SiB6 under gamma irradiation dose. 
    Mirzayev, M. N.; Jabarov, S. H.; Asgerov, E. B.; Mehdiyeva, R. N.; Thabethe, T. T.; Biira, Saphina; Tiep, N. V. (Springer., 2018)
    The silicide hexaboride (B6Si) was irradiated with 60Co at room temperature to study the structural changes and weight kinetics. The B6Si samples were irradiated using a gamma source with a dose rate (D) of 0.27 Gy/s. At ...
