  • Fragment formation in the break-up of a drop falling in a miscible liquid 
    Arecchi, F. T.; Buah-Bassuah, P. K.; Perez-Garc, C. (University of Cape Coast, 1991)
    When falling in a lighter miscible solvent, a drop of liquid deforms to a torus which then breaks up into several fragments or just disappears by diffusion. By using liquids of different compositions we show the universal ...
  • Fragmentation instabilities of a drop as it falls in a miscible fluid 
    Residori, S.; Buah-Bassuah, P.K.; Arecchi, F.T. (University of Cape Coast, 2007)
    We review here a series of experiments on the fragmentation instabilities that a liquid drop undergoes it falls inside a fluid with which it is miscible, so called the solvent. Motivated by the original experiments initiated ...

    Dadzie, Samuel K. N.; Dasmani, Isaac (University of Cape Coast, 2010-11-29)
    Gender mainstreaming has, for some time now, been identified as a paramount issue in development of resource-poor societies, and particularly, the women whose access to productive resources is limited due to tradition, ...
  • Gene action of cassava resistance metabolites to whitefly (Bemisia tabaci)
