Temporal genetic differentiation in Glossina pallidipes tsetse fly populations in Kenya.
(University of Nairobi, 2017)BACKGROUND: Glossina pallidipes is a major vector of both Human and Animal African Trypanosomiasis (HAT and AAT) in Kenya. The disease imposes economic burden on endemic regions in Kenya, including south-western Kenya, ... -
2-Butanone as a carbon dioxide mimic in attractant blends for the Afrotropical malaria mosquitoes Anopheles gambiae and Anopheles funestus.
(University of Nairobi, 2017)BACKGROUND: Most odour baits designed to attract host-seeking mosquitoes contain carbon dioxide (CO2), which enhances trap catches, given its role as a mosquito flight activator. However, the use of CO2 is expensive and ... -
Secondary bacterial infections and antibiotic resistance among tungiasis patients in Western, Kenya.
(University of Nairobi, 2017)Tungiasis or jigger infestation is a parasitic disease caused by the female sand flea Tunga penetrans. Secondary infection of the lesions caused by this flea is common in endemic communities. This study sought to shed light ... -
Current status of insecticide resistance among malaria vectors in Kenya.
(University of Nairobi, 2017)BACKGROUND: Insecticide resistance has emerged as one of the major challenges facing National Malaria Control Programmes in Africa. A well-coordinated national database on insecticide resistance (IRBase) can facilitate ... -
Dominant Allele Phylogeny and Constitutive Subgenome Haplotype Inference in Bananas Using Mitochondrial and Nuclear Markers.
(University of Nairobi, 2017)Cultivated bananas (Musa spp.) have undergone domestication patterns involving crosses of wild progenitors followed by long periods of clonal propagation. Majority of cultivated bananas are polyploids with different ... -
Target-similarity search using Plasmodium falciparum proteome identifies approved drugs with anti-malarial activity and their possible targets.
(University of Nairobi, 2017)Malaria causes about half a million deaths annually, with Plasmodium falciparum being responsible for 90% of all the cases. Recent reports on artemisinin resistance in Southeast Asia warrant urgent discovery of novel drugs ... -
Temperature and heat in informal settlements in Nairobi.
(University of Nairobi, 2017)Nairobi, Kenya exhibits a wide variety of micro-climates and heterogeneous surfaces. Paved roads and high-rise buildings interspersed with low vegetation typify the central business district, while large neighborhoods of ... -
Quantifying the intensity of permethrin insecticide resistance in Anopheles mosquitoes in western Kenya.
(University of Nairobi, 2017)BACKGROUND: The development and spread of resistance among local vectors to the major classes of insecticides used in Long-Lasting Insecticidal Nets (LLINs) and Indoor Residual Spraying (IRS) poses a major challenge to ... -
Identification of spiroplasmainsolitum symbionts in anopheles gambiae.
(University of Nairobi, 2017)Background: Insect symbionts have the potential to block the transmission of vector-borne diseases by their hosts. The advancement of a symbiont-based transmission blocking strategy for malaria requires the identification ... -
Developing a bacteriophage cocktail for biocontrol of potato bacterial wilt
(University of Nairobi, 2017)Bacterial wilt is a devastating disease of potato and can cause an 80% production loss. To control wilt using bacteriophage therapy, we isolated and characterized twelve lytic bacteriophages from different water sources ... -
Firefly Algorithm based Power Control in Wireless TV White Space Network
(University of Nairobi, 2017)Spectrum occupancy assessments done in USA, Spain, Singapore, New Zealand and Germany [1] and UK [2], indicate that a large portion of spectrum assigned to primary users (PUs) is underutilized. Spectrum is considered a ... -
Automobile Battery Monitoring System using Arduino Uno R3 Microcontroller Board
(University of Nairobi, 2017)The car starter battery normally provides electrical power for engine cranking, lighting of accessories and feeding the engine ignition system. During any given car engine cranking event, a high current ranging from ... -
Biodegradation and Detoxification of Malachite Green Dye Using Novel Enzymes from Bacillus cereus Strain KM201428: Kinetic and Metabolite Analysis
(University of Nairobi, 2017)Enzyme based degradation of organic pollutants is a promising detoxifying approach due to the promiscuous nature of the enzyme, efficiency, cost effective and ecofriendly. In the present study, we have carried out detailed ... -
Equilibrium and Kinetic Studies of Cu(Ii) Removal from Aqueous Solutions Using a Kenyan Micaceous Mineral.
(University of Nairobi, 2017)Copper (II) sorption on a Kenyan micaceous mineral (Mica-K) was studied in the batch mode. The effects of different experimental parameters such as; initial concentration, contact time, sorbent dose, pH, particle size, ... -
Amino acid Composition of Gelatin Extracted from the Scales of Different Marine Fish Species in Kenya
(University of Nairobi, 2017)Gelatin in this study was extracted by an enzymatic process from the scales of three marine fish species; Lutjanus sebea (Red snapper), Lethrinus harak (Black spot emperor) and Scalus ghobban (Blue barred parrot ... -
A nested multivariate chemometrics based calibration strategy for direct trace biometal analysis in soft tissue utilizing Energy Dispersive X-Ray Fluorescence (EDXRF) and scattering spectrometry.
