    • On Unitary Quasi-equivalence of Operators 

      Nzimbi, Benard M; Wanyonyi, Stephen L (University of Nairobi, 2020)
      In this paper we investigate unitary quasi-equivalence of operators in Hilbert spaces. We characterize operators that are unitarily quasi-equivalent. We also investigate equivalence relations closely related to unitary ...

    • The Role of Organizing Vision in Cloud Computing Adoption by Organizations in Kenya 

      Oredo, John; Njihia, James; Iraki, XN (University of Nairobi, 2017)
      Cloud computing as an emerging IT innovation has attracted a growing number of studies in recent years. Key amongst these studies is the adoption of cloud computing. Most studies investigating cloud computing adoption have ...

    • Tectonic Structures Across The East African Rift Based On The Source Parameters Of The 20 May 1990 M7.2 Sudan Earthquake 

      Mulwa, JK; Kimata, F (Universty of Nairobi, 2014)
      Earthquakes in Kenya are common along the Kenya Rift Valley due to the slow divergent movement of the rift and hydrothermal processes in the geothermal fields. This implies slow but continuous radiation of seismic energy ...

    • Transgenic Expression of Dsrna Targeting the Pentalonia Nigronervosa Acetylcholinesterase Gene in Banana and Plantain Reduces Aphid Populations 

      Jekayinoluwa, Temitope; Jaindra, Nath T; Dugtale, Benjamin; Obiero, George; Muge, Edward; Dale, James; Tripathi, Leena (University of Nairobi, 2021)
      The banana aphid, Pentalonia nigronervosa, is the sole insect vector of banana bunchy top virus (BBTV), the causal agent of banana bunchy top disease. The aphid acquires and transmits BBTV while feeding on infected banana ...

    • Upper limits for undetected trace species in the stratosphere of Titan 

      Conor, Nixon A; Achterberg, Richard K; Teanby, Nicholas A; Irwin, Patrick G; Flaud, Jean-Marie; Kleiner, Isabelle; Dehayem-Kamadjeu, Alix; Brown, Linda R; Sams, Robert L; Bezard, Bruno; Coustenis, Athena; Ansty, Todd M.; Mamoutkine, Andrei; Vinatier, Sandrine; Bjoraker, Gordon L; Jennings, Donald E; Romani, Paul. N.; Flasar, F. Michael (University of Nairobi, 2010)
      In this paper we describe the first quantitative search for several molecules in Titan's stratosphere in Cassini CIRS infrared spectra. These are: ammonia (NH3), methanol (CH3OH), formaldehyde (H2CO), and acetonitrile ...

    • Variation in Morphological and Agronomic Traits of Selected African Eggplant Accessions 

      Tembe, Kenneth; Lagat, Samson; Ambuko, Jane; Chemining'wa, George; Owino, Willis (University of Nairobi, 2020)
      The African eggplant is an important indigenous vegetable crop in Africa. However, there is limited information on variations among the wild species that could potentially act as a source for crop improvement. A study ...
