(2015-08)This study sought to establish the relationship between Corporate Social Responsibility strategy and the financial performance of deposit taking Savings and Credit Co-operatives societies in Kenya. The SACCO subsector is ... -
Cramer-Rao Bound of Direction Finding Using a Uniform Hexagonal Array
(2019-06)Direction-of-arrival (DOA) estimation is a key area of sensor array processing which is encountered in many important engineering applications. Although various studies have focused on the uniform hexagonal array for ... -
Cramer-Rao Bound of Direction Finding Using Uniform Arc Arrays
(2019)Direction-of-Arrival estimation accuracy using arc array geometry is considered in this paper. There is a scanty use of Uniform Arc Array (UAA) in conjunction with Cram er-Rao bound (CRB) for Direction-of-Arrival estimation. ... -
Crame´R-Rao Bound of Direction Finding using Uniform Circular Array And 2-Circle Concentric Uniform Array
(2019-09)Source direction-of-arrival estimation problem has received much attention in recent years following its significant role in array-signal processing and wide range of applications such as radar, wireless communication, ... -
Crop residues used as lignocellulose materials for particleboards formulation
(Heliyon, 2020-09)Efforts to reduce pressure on use of wood in particleboard formulation have included the use of non-wood materials such as crop residues. Physical and mechanical properties are determined by the number of the hydroxyl (-OH) ... -
Cultural Characterization of Fungi Isolated From Oil Contaminated Soils
(IISTE, 2015)Application of Fungi for effective removal of hydrocarbon contamination from soil is being considered as the better option when it comes to biodegradation. Other method like physical and chemical bioremediation leads to ... -
Curriculum resources and academic performance of distance learning students in selected Kenyan public universities
(IISTE, 2018)Distance learning is a mode of study which involves the separation of the lecturer from the student in space, time or both. The mode of study is increasingly being adopted globally due to development in technology, ... -
A cyano-anomaly? Cyanobacterial toxins as contributors to Lesser Flamingo mass deaths
(2003-10)In the present study, significative HAB’S bloom was confirmed in Matanchén Bay during Febrary 2003. The Raphidophice Fibrocapsa cf. japonica, Toriumi et Takano 1973 (=Chatonella japonica) has dominated (97%) red ... -
Cyanobacteria and cyanobacterial toxins in the alkaline crater lakes Sonachi and Simbi, Kenya
(Elsevier, 2005-01)The phytoplankton communities and the production of cyanobacterial toxins were investigated in two alkaline Kenyan crater lakes, Lake Sonachi and Lake Simbi. Lake Sonachi was mainly dominated by the cyanobacterium Arthrospira ... -
Cyanobacterial diversity in the hot spring, pelagic and benthic habitats of a tropical soda lake
(2013-08)Hot springs and saline-alkaline lakes of East Africa are extreme habitats regarding temperature, or salinity and pH, respectively. This study examines whether divergent habitats of Lake Bogoria, Kenya, impacts cyanobacterial ... -
