Subdegrees and suborbital graphs of symmetric group s n (n = 3, 4, 5) acting on unordered pai rs
(2015)In this research paper, we compute the ranks and subdegrees of the symmetric group S n (n = 3, 4, 5) acting on unordered pairs from the set X = When S n (n ≥ 4) acts on unordered pairs from X, the rank ... -
Orbito-Maxillofacial Cutaneous Anthrax
(2015)Background: Cutaneous anthrax is a zoonotic disease that spreads to humans primarily through exposure to infected animals, animal products or spore infested soil. Microbiological identification of cutaneous anthrax may be ... -
Famers' Requirements in an Artificial Intelligent System for Diagnosis of Maize Diseases in Kenya
(University of Nairobi, 2015)A study was conducted to determine the following: commonly used sources of agricultural diagnostic information by maize farmers, content of information which farmers would like to receive for full satisfaction on diagnostics, ... -

(2016)Background: A prophylactic HIV-1 vaccine is a global health priority. Objective: To assess a novel vaccine platform as a prophylactic HIV-1 regimen. Design: Randomized, double-blind, placebo-controlled trial. Both ... -
Clinical Features Associated with Group A Rotavirus in Children Presenting with Acute Diarrhoea at Kenyatta National Hospital, Nairobi, Kenya
(2016)Background: Worldwide rotavirus (RV) infection is a major cause of diarrhea in children <5 years of age. Continual monitoring of RV prevalence and its associated clinical characteristics is necessary to estimate the burden ... -
Khat use and khat induced oral white lesions among khat and tobacco users at two sites in Kenya
(2015)Abstract Background: Long term chewing of khat is associated with white lesions on the oral mucosa some of which depict histopathological changes. However, due to the limited number of studies in this area, the clinical ... -

(2015)Severe acute malnutrition is a widely prevalent problem in developing countries and a major cause of morbidity and mortality. Traditionally, children with severe acute malnutrition were rehabilitated within inpatient ... -
Adherence of healthcare practitioners to the adolescent reproductive health and development policy at The Garissa Provincial General Hospital, Kenya
(2015)Background: Kenya’s policies relating to population, family planning (FP) and reproductive health (RH) receive weak/fluctuating levels of adherence. The Adolescent Reproductive Health and Development (ARH&D) policy gives ... -
An Optimal Eigenvalue Based Spectrum Sensing Algorithm for Cognitive Radio
(2015)Spectrum is a scarce resource, and licensed spectrum is intended to be used only by the spectrum owners. Various measurements of spectrum utilization have shown unused resources in frequency, time and space. Cognitive ... -
Extension Officers' Requirements in an artificial Intelligent System for Diagnosis of Maize Disease, Kenya
(University of Nairobi, 2015)A study was conducted to determine the most frequently used agricultural diagnostic information source by extension officers, the content of information which both the extension officer would like to receive for full ... -
Comparative analysis of ear-hole closure identifies epimorphic regeneration as a discrete trait in mammals
(2016)Why mammals have poor regenerative ability has remained a long-standing question in biology. In regenerating vertebrates, injury can induce a process known as epimorphic regeneration to replace damaged structures. ... -
A review of techniques in optimal sizing of hybrid renewable energy systems
(2015)This paper presents a review of techniques usedin recent published works on optimal sizing of hybrid renewable energy sources. Hybridization of renewable energy sources is an emergent promising trend born out of the need ... -
Combined Real and Reactive Power Economic Dispatch using Multi-Objective Reinforced Learning with Optimized Losses
(2015)Most of the economic dispatch (ED) works so far deal with real power dispatch only. With the integration of renewable energy into the grid, reactive power dispatch cannot be ignored any longer due to its importance in ... -
Distributed transmit-power control in cognitive radio networks using a hybrid-adaptive game-theoretic technique
(2015)This paper studies game-theoretic distributed transmit-power control in a cognitive radio network. It presents a hybrid-adaptive algorithm that interfaces Iterative Water-Filling with two learning algorithms: the Hedging ... -
Relational patterns of urbanisation and economic growth in sub-Saharan Africa
(2016)Scholars of economic development have always hinted that the urbanisation process in the developing world does not follow the historical patterns discerned in the developed world where a strong relationship between a ... -
Common mental disorder in Nyanza province, Kenya in 2013 and its associated risk factors –an assessment of change since 2004, using a repeat household survey in a demographic surveillance site
(2015)Background Repeat household surveys are useful to assess change in prevalence over time, but there have been no repeat surveys of common mental disorder (CMD) in Kenya, or indeed sub-Saharan Africa. Therefore a repeat ... -
