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 ...
Synergistic anti-inflammatory activities of a new flavone and other flavonoids from Tephrosia hildebrandtii vatke
(University of Nairobi, 2020)
A new flavone, named hildeflavone (1) along with 7 other known flavonoids were isolated from the aerial parts of Tephrosia hildebrandtii Vatke. Their characterisation was based on NMR and MS data analysis. The anti-inflammatory ...
Radiometric Survey of the Tyaa River Sand Mine in Kitui, Kenya
(University of Nairobi, 2020)
Gamma spectroscopic analyses of sand and rock samples from Tyaa River report an average activity concentration of 33 ± 1, 55 ± 2.8 and 812 ± 40.46 Bqkg-1 for 226Ra, 232Th and 40K, respectively in the sand. A similar analysis ...
Spatial and temporal trends of polychlorinated biphenyls in water and sediment from Nairobi River, Kenya
(University of Nairobi, 2020)
Polychlorinated biphenyls (PCBs) are chemicals that have become ubiquitous environmental pollutants due to their past use, persistence, and long-range transport thus requiring continuous monitoring. Therefore, this research ...
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 ...
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 ...
Characterization of Water Hyacinth Cellulose-g-poly (Ammonium Acrylate-co-acrylic Acid)/nano-hydroxyapatite Polymer Hydrogel Composite for Potential Agricultural Application
(University of Nairobi, 2020)
Polymer nano-composite was prepared by grafting partially neutralized acrylic acid onto swollen cellulose iso-lated from water hyacinth in the presence of nano-hydroxyapatite (nano-HA) usingN,N-methylene-bis-acrylamide ...
Varietal differences in physiological and biochemical responses to salinity stress in six finger millet plants
(University of Nairobi, 2020)
Finger millet is an important cereal that is grown in semi-arid and arid regions of East-Africa. Salinity stress is a major environmental impediment for the crop growth and production. This study aimed to understand the ...
