Tryptophan-like and humic-like fluorophores are extracellular in groundwater: implications as real-time faecal indicators
(University of Nairobi, 2020)
Fluorescent natural organic matter at tryptophan-like (TLF) and humic-like fluorescence (HLF) peaks is associated with the presence and enumeration of faecal indicator bacteria in groundwater. We hypothesise, however, that ...
Proximity Density Assessment and Characterization of Water and Sanitation Facilities in the Informal Settlements of Kisumu City: Implications for Public Health Planning
(University of Nairobi, 2020)
Access to water and sanitation remain a challenge in many developing countries, especially in pro-poor urban informal settlements where socioeconomic livelihoods are generally low. The aim of this study was to characterise ...

Validation of a Quantitative Proton Nuclear Magnetic Resonance Spectroscopic Screening Method for Coffee Quality and Authenticity (NMR Coffee Screener)
(University of Nairobi, 2020)
Monitoring coffee quality as a means of detecting and preventing economically motivated fraud is an important aspect of international commerce today. Therefore, there is a compelling need for rapid high throughput validated ...
Investigation of the Electrocatalytic Properties of Spherical Palladium Nanoparticles and Palladium (100) Iridium Bimetallic Nanocomposites Towards Ammonia Electrooxidation on …
(University of Nairobi, 2015)
The electrocatalytic properties of cubic palladium-iridium {Pd(100)Ir} bimetallic nanocomposite and spherical nanoparticles {Pd NPs} towards the electrochemical oxidation of ammonia were investigated in sodium hydroxide ...
Formulation of Slow Release Npk Fertilizer (Cellulose-graft-poly (Acrylamide)/nano-hydroxyapatite/soluble Fertilizer) Composite and Evaluating Its N Mineralization Potential
(University of Nairobi, 2018)
Polymer nano-composite fertilizer formulation has the potential to enhance nutrient use efficiency. Slow release
fertilizer (SRF) composite was formulated by incorporating nano-hydroxyapatite (nano-HA) and water ...
Biochemical Methane Potential (BMP) of Market Wastes from Nairobi Inoculated With Dagoretti Slaughterhouse Waste
(University of Nairobi, 2020)
Background: Anaerobic degradation entails the conversion of substrate organic
matter to biogas. A wide variety of substrate has been employed. The
biochemical methane potential of twenty market wastes was investigated ...
Changes in Phytochemical Content During Different Growth Stages in Tubers of Five Varieties of Potato (Solanum Tuberosum
(University of Nairobi, 2018)
Potato (Solanum tuberosum L.) synthesizes a variety of bioactive metabolites including phenolic compounds and glycoalkaloids that protects against insects and diseases, and may influence its nutritional quality. ...
Expansions of chemosensory gene orthologs among selected tsetse fly species and their expressions in Glossina morsitans morsitans tsetse fly
(University of Nairobi, 2020)
Tsetse fly exhibit species-specific olfactory uniqueness potentially underpinned by differences in their chemosensory protein repertoire. We assessed 1) expansions of chemosensory protein orthologs in Glossina morsitans ...
A microsporidian impairs Plasmodium falciparum transmission in Anopheles arabiensis mosquitoes
(University of Nairobi, 2020)
A possible malaria control approach involves the dissemination in mosquitoes of inherited symbiotic microbes to block Plasmodium transmission. However, in the Anopheles gambiae complex, the primary African vectors of ...
