Biosorption of Malachite Green from Aqueous Solutions onto Polylactide/Spent Brewery Grains Films: Kinetic and Equilibrium Studies
(2012)
Batch experiments were conducted to study the biosorption of Malachite Green (MG) onto polylactide (PLA)/spent brewery grains (SBGs) films. Films were prepared by solvent-casting method using dichloromethane. Effects of ...
Identification Of Candidate Volatiles That Affect The Behavioural Response Of The Malaria Mosquito Anopheles Gambiae Sensu Stricto To An Active Kairomone Blend: Laboratory And Semi-field Assays
(University of Nairobi, 2012)
Anopheles gambiae Giles sensu stricto (Diptera: Culicidae) is the most important vector of human malaria in sub-Saharan Africa, affecting the lives of millions of people. Existing tools such as insecticide-treated nets and ...

(2012)
Schistosomiasis infects approximately 700 million people in 74 endemic countries. It causes high morbidity. Although the drug of choice, Praziquantel is effective against Schistosoma mansoni, there is a problem of rapid ...
Use of MapReduce for Data Mining and Data Optimization on a Web Portal
(2012-12)
This paper studied the design, implementation and evaluation
of a MapReduce tool targeting distributed systems, and multicore
system architectures. MapReduce is a distributed
programming model originally proposed by ...
Protein-RNA interface residue prediction using machine learning: an assessment of the state of the art
(2012)
RNA molecules play diverse functional and structural roles in cells. They function as messengers for transferring genetic information from DNA to proteins, as the primary genetic material in many viruses, as catalysts ...
High-Frequency Regeneration of the Drought-Tolerant Tree Melia volkensii Gurke Using Low-Cost Agrochemical Thidiazuron
(Hindawi Publishing Corporation, 2012-10)
Melia volkensii Gurke is a drought-tolerant tree native to East Africa’s arid and semiarid lands (ASALs), with vast but underutilized
potential for agroforestry and sustainable livelihoods in the ASALs. Its cultivation ...

East African mid-Holocene wet-dry transition recorded in palaeo-shorelines of Lake Turkana, northern Kenya Rift.
(University of Nairobi, 2012-05-15)
The ‘wet’ early to mid-Holocene of tropical Africa, with its enhanced monsoon, ended with an abrupt shift toward drier conditions and was ultimately replaced by a drier climate that has persisted until the present day. The ...
Hyperspectral remote sensing of evaporate minerals and associated sediments in Lake Magadi area, Kenya
(University of Nairobi, 2012-02)
Pleistocene to present evaporitic lacustrine sediments in Lake Magadi, East African Rift Valley, Kenya were studied and mapped using spectral remote sensing methods. This approach incorporated surface mineral mapping using ...
