    • Thermal Conductivities of Selected Solid Waste Materials Determined Using Lees’ Disc Method 

      Chepkorir, Doreen; Kamweru Kuria, Paul (International Journal of Research Publications (IJRP.ORG), 2020-04-02)
      In this study, the coefficients of thermal conductivities have been determined. The goal was to find out the best insulator among the recyclable and locally available materials which can be adopted for use to replace the ...

    • Trimetallic complexes containing Nickel or Palladium and two Molybdenum nitrosyl groups 

      Kagwanja, Stanley M.; Johns, Christopher J.; McCleverty, Jon A. (1997)
      The reaction of [Mo(NO){HB(dmpz)3}Cl2] [HB(dmpz)3 = tris(3,5-dimethylpyrazolyborate] with nickel(II) and palladium(II) Schiff-base complexes derived by condensation of two mole equivalents of 2,5-dihydroxybenzaldehyde with ...

    • UV Absorption and dynamic mechanical analysis of polyethylene films 

      Kamweru, Paul; Ndiritu, Francis; Kinyanjui, Thomas; Muthui, Zipporah wanjiku; Ngumbu, Richard; Odhiambo, Peter Migunde (2014-12)
      Photooxidative processes that lead to chain scission and chain linking in polymers play an important role in polymer degradation. These processes are induced by both ultraviolet (UV) and visible light absorption. The ...

    • Volatility Modelling of the Nairobi Securities Exchang 

      Wagala, Adolphus; Nassiuma, Dankit K.; Islam, Ali S.; Mwangi, Jesse W. (2012-03)
      In this paper we identify the most efficient ARCH-type model that can be applied to the Nairobi stock exchange data for forecasting and prediction of volatility which in turn is important in pricing financial derivative ...
