Interactive influence of rainfall manipulation and livestock grazing on species diversity of the herbaceous layer community in a humid savannah in Kenya
(Elsevier, 2019)Changes in rainfall regime and grazing pressure affect vegetation composition and diversity with ecological implications for savannahs. The savannah in East Africa has experienced increased livestock grazing and rainfall ... -
Predictors of Ocular Surface Squamous Neoplasia and Conjunctival Squamous Cell Carcinoma among Ugandan Patients: A Hospital-based Study
(Wolters Kluwer--Medknow Publications, 2018)AIM: The aim of the study was to assess the predictors of ocular surface squamous neoplasia (OSSN) and conjunctival squamous cell carcinoma (SCC) among Ugandan patients. MATERIALS AND METHODS: Patients presenting for ... -
The management of microbial keratitis within Uganda’s primary health system: a situational analysis
(The Wellcome Trust, 2019)Background: Microbial keratitis (MK) frequently leads to sight-loss, especially when the infection is severe and/or appropriate treatment is delayed. The primary health system as an entry point plays a central role in ... -
Traditional eye medicine use in microbial keratitis in Uganda: a mixed methods study
(The Wellcome Trust, 2019)Background: Traditional eye medicine (TEM) is frequently used to treat microbial keratitis (MK) in many parts of Africa. Few reports have suggested that this is associated with a worse outcome. We undertook this large ... -
Delay Along the Care Seeking Journey of Patients with Microbial Keratitis in Uganda
(Taylor & Francis, 2019)PURPOSE To describe the care seeking journey and causes of delay among patients with Microbial Keratitis in Uganda. METHODS A prospective cohort of patients presenting with microbial keratitis at the two main eye units ... -
The management of microbial keratitis within Uganda’s primary health system: a situational analysis
(Wellcome Open Research, 2019)Background: Microbial keratitis (MK) frequently leads to sight-loss, especially when the infection is severe and/or appropriate treatment is delayed. The primary health system as an entry point plays a central role ... -
The impact of microbial keratitis on quality of life in Uganda
(BMJ Specialist Journals, 2019)Background Microbial keratitis (MK) is a frequent cause of sight loss in sub-Saharan Africa. However, no studies have formally measured its impact on quality of life (QoL) in this context. Methods As part of a nested ... -
Risk Factors of Microbial Keratitis in Uganda: A Case Control Study
(Taylor & Francis, 2020)Purpose: Microbial keratitis (MK), is a frequent cause of sight loss worldwide, particularly in low and middle-income countries. This study aimed to investigate the risk factors of MK in Uganda. Methods: Using a nested ... -
Epidemiology of Microbial Keratitis in Uganda: A Cohort Study
(Taylor & Francis, 2020)Purpose: To describe the epidemiology of Microbial Keratitis (MK) in Uganda. Methods: We prospectively recruited patients presenting with MK at two main eye units in Southern Uganda between December 2016 and March 2018. ... -
Smartphone-based Ophthalmic Imaging Compared With Spectral-domain Optical Coherence Tomography Assessment of Vertical Cup-to-disc Ratio Among Adults in Southwestern Uganda
(NIH Public Access, 2021)Precis: Using optical coherence tomography (OCT) measurements as a reference standard for vertical cup-to-disc ratio (vCDR), a smartphone-based ophthalmic camera has a sensitivity of 67.7% and specificity of 96.7% to detect ... -
Ecosystem productivity and CO2 exchange response to the interaction of livestock grazing and rainfall manipulation in a Kenyan savanna
(Elsevier, 2021)Savanna ecosystems in Kenya are experiencing altered rainfall amount and increased grazing pressure. These environmental alterations occur simultaneously and impact on productivity and CO2 exchange of the savanna in unclear ... -
A ten-year study of Retinoblastoma in Uganda: An approach to improving outcome with limited resources
(Elsevier, 2021)Background: Survival of children with cancer in resource-limited regions is very poor compared to betterresourced regions. Retinoblastoma (RB) is a childhood cancer that is commonly reported in many regions of Africa. RB ... -
Optical properties and Raman studies of amorphous se-bi thin films
(The African Review of Physics, 2014)Flash evaporated amorphous Se Bi (x = 0, 1, 2, 3, and 4 at. %) thin films of 350 ± 10 thickness have been investigated in the wavelength range of 200nm − 3000nm. It is found that the effect of increasing bismuth content ... -
Investigation of the effect of film thickness on the optical properties of amorphous Se85-xte15sbx thin films
(Africa Journal of Physical Sciences, 2014)Amorphous thin films of Se85-xTe15Sbx (x = 0.0, 0.5, 2.5, and 5.0 at. %) deposited by flash evaporation technique, have been investigated in the wavelength range of 500nm-3000nm. It is found that the effect of increasing ... -
Compositional and Thickness Effects on the Optical Properties of Zinc– Doped Selenium–Antimony Thin Films
(AJOL, 2018)Chalcogenide system of antimony (Sb)-selenium (Se)-zinc (Zn) system is a promising semiconductor for phase change memory devices due to its thermal stability and low power consumption. The study investigated the effect ... -
Mineral nutrient uptake of maize and banana in an intercrop with agroforestry tree species in Vihiga County, Kenya
(IAR Journal of Agriculture Research and Life Sciences, 2021)Western Kenya faces high population pressure and this has increased demand for food. Smallholder farmers in the region have been forced to practice poor farming practices such as continuous cultivation and clearing of ... -
Radio Exposure and Drivers of Electoral Participation among Women Voters under the New Devolved Political Structure in Kenya
(Romanian Journal of Communication and Public Relations, 2021)Radio dominates the news media ecosystem in Kenya. However, little is known about the relationship between radio exposure and drivers of electoral participation in Kenya. This research thus examines the correlation between ... -
Investigation of long acoustic waveguides for the very low frequency characterization of monolayer and stratified air-saturated poroelastic materials
(Elsevier, 2021)When sound propagates in a porous medium, it is attenuated via several energy loss mechanisms which are switched on or off as the excitation frequency varies. The classical way of measuring acoustic energy loss in porous ... -
