Upper limits for undetected trace species in the stratosphere of Titan
(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 ... -
ANSOLE Mini-Symposium in Kenya (AMSK 2013) 9. May 2013, Nairobi Kenya
(University of Nairobi, 2013)Energy is the main driver in any economy because almost everything is directly or indirectly related to energy. Energy determines to a large extend the prices of goods, commodities , services and hence the cost of living ... -
Alienusolin, a new 4α-deoxyphorbol ester derivative, and crotonimide C, a new glutarimide alkaloid from the Kenyan Croton alienus.
(2013-12)Two novel compounds, alienusolin, a 4α-deoxyphorbol ester (1), crotonimide C, a glutarimide alkaloid derivative (2), and ten known compounds, julocrotine (3), crotepoxide (4), monodeacetyl crotepoxide (5), dideacetylcrotepoxide, ... -
Tectonic Structures Across The East African Rift Based On The Source Parameters Of The 20 May 1990 M7.2 Sudan Earthquake
(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 ... -
Electronic Properties of Catechol Adsorbed on Rutile TiO2 and SnO2 (110) Surfaces: A Density Functional Theory Study
(University of Nairobi, 2016)The incorporation of organic molecules such as catechol onto TiO2 substrate to enhance TiO2 photocatalytic activity has led to improved Dye Sensitized Solar Cells (DSSCs) efficiency. Nonetheless, it still remains low for ... -
Influence of Pore Size on the Optical and Electrical Properties of Screen Printed Thin Films
(University of Nairobi, 2016)Influence of pore size on the optical and electrical properties of TiO2 thin films was studied. TiO2 thin films with different weight percentages (wt%) of carbon black were deposited by screen printing method on fluorine ... -
The E-government Paradox: Is It Real and How Can It Be Resolved?
(University of Nairobi, 2016)The development and implementation of e-government has been viewed as an opportunity to bring the much-desired reforms in public administration. There are several studies that have been conducted in the field of e-government ... -
Compositional analysis and optical properties of Co doped TiO2 thin films fabricated by spray pyrolysis method for dielectric and photocatalytic applications
(University of Nairobi, 2017)Cobalt doped TiO2 thin films (CTF) deposited by spray pyrolysis has been studied. The compositional analysis has been done using RBS method, while optical spectroscopy has been done by measuring the transmittance and ... -
The Role of Organizing Vision in Cloud Computing Adoption by Organizations in Kenya
(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 ... -
Assessment and mapping of the high background radiation anomaly associated with laterite utilization in the south coastal region of Kenya
(University of Nairobi, 2019)Laterite is commonly used in Kenya and other tropical countries as an aggregate material for road paving. However, the use and relocation of laterite and other geological materials from high background radiation areas ... -
Effect Of Deposition Temperature On The optical Properties Of Iron-Doped Cadmium Stannate Thin Films Deposited By Spray Pyrolysis
(University of Nairobi, 2019)Spray Pyrolysis Technique (SPT) was used to deposit thin films (TFs) of cadmium stannate, doped with iron (Fe) for the first time. The precursor solutions that were used wereprepared at a concentration of 0.1M, doped ... -
Enhancing Access and Use of Climate Information Through ICTs
(University of Nairobi, 2019)Although the role of ICTs in improving human life in Kenya is acknowledged widely, the focus of much of ICT-related developments has been on human experiences at the level of disease and needs for communication and mobility. ... -
Effect of Hexanal as a Post-harvest Treatment to Extend the Shelf-life of Banana Fruits (Musa acuminata var. Sweet Banana) in Kenya
(University of Nairobi, 2019)The short shelf-life of fruits in the tropics continues to be a pressing problem for farmers and other value chain actors. Hexanal is a naturally occurring compound that has received attention as a novel postharvest ... -
Institutional Pressures and Cloud Computing Adoption: the Moderating Effect of Organizational Mindfulness
