(AJPS, 2022-12-16)
The Anza Rift is a northwest-southeast trending sedimentary basin located in northern Kenya. This is one of the remaining underexplored frontier exploration areas possessing high potential in hydrocarbon discoveries ...
Mathematical competitions in Africa: their prevalence and relevance to students and teachers
(University of Nairobi, 2022)
Mathematical competitions feature in most developed countries as a part of the secondary school experience, but to a lesser extent in developing countries. In this paper we investigate how widespread these competitions are ...
Direct rapid quality assurance analysis of complex matrix materials: A chemometrics enabled energy dispersive X-ray fluorescence and scattering spectrometry application
(University of Nairobi, 2022)
Compared to energy dispersive X-ray fluorescence (EDXRF) that is limited to analysis of elements (Z ≥ 13) via fluorescence and which is hardly direct, energy dispersive X-ray fluorescence and scattering (EDXRFS) spectrometry ...
Impacts of hydro climatic conditions on lesser flamingo, Phoeniconaias minor, Geoffroy populations in three Kenyan alkaline lakes.
(AJPS, 2022-12-31)
Hydro climatic conditions are critical factor determinants of lesser flamingo ecology in the alkaline Lakes of Nakuru, Elementaita and Bogoria in Kenya. Based on lake levels, rainfall and ...
Phenotypic characterization of phage vB_vcM_Kuja
(University of Nairobi, 2023)
Bacteriophage therapy targeting the increasingly resistant Vibrio cholerae is highly needed. Hence, studying the phenotypic behavior of potential phages under different conditions is a prerequisite to delivering the phage ...
In Vitro Antimicrobial and Antiproliferative Activities of the Root Bark Extract and Isolated Chemical Constituents of Zanthoxylum Paracanthum Kokwaro (Rutaceae)
(University of Nairobi, 2020)
Abstract: Zanthoxylum paracanthum Kokwaro (Rutaceae) is an endemic Kenyan and Tanzanian
plant used in folk medicine by local populations. Although other Zanthoxylum species have been
studied, only Z. paracantum stem ...
