    In medical exposure dose to patients are determine by input parameters including mAs, kVp, pitch factor among other factors. The aim of this study is to provide procedure and protocol of how to assess patients’ dose (organ ...
  • Ishiekwene, G.C.; Mensah, S.Y.; Brown, C.S. (University of Cape Coast, 2000)
    An intensity-dependent change in ellipticity of an input light beam leads to a characteristic shift in polarization instability. The presence of dichroism gives rise to self-induced ellipticity effect in the polarization ...
  • Marcano, Aristides; Basaldua, Isaac; Villette, Aaron; Edziah, Raymond; Liu, Jinjie; Ziane, Omar; Melikechia, Noureddine (University of Cape Coast, 2013)
    We measured the photothermal lens signal in samples exhibiting high turbidity using a pump-probe scheme. We show that the photothermal lens signal properties remain nearly unchanged up to values of turbidity of 6 cm1 despite ...
  • Musah, Rabiu (University of Cape Coast, 2012)
    We used a complete tight-binding band structure of grapheme nanoribbon to obtain, for the first time, analytical techniques for observing photon assisted transport, and dynamic localization of electrons in the graphene ...
  • Sackey, S. S.; Mensah-Amoah, P.; Amoako, G.; Vowotor, M. K.; Sefa-Ntiri, B.; Birikorang, E. (University of Cape Coast, 2019)
    Microbial bacteria in well-water have been treated using three different radiations and efficiency of treatment determined. The radiations were SUV (Sun with UV); SNoUV (Sun with NoUV, sun with UV portion filtered out) and ...

    We report a new type of drop instability, where the density difference between the drop and the solvent is negative. We show that the drop falls inside the solvent down to a minimum height, then fragmentation takes place ...
  • Ishiekwene, G.C.; Mensah, S.Y.; Brown, C.S. (University of Cape Coast, 2001)
    The nonlinear polarization effects in a birefringent single mode optical fiber are studied using Jacobi elliptic functions. We find that the polarization state of the propagating beam depends on the initial polarization ...
