The monotypic genus Bulborrhizina belongs to Bulbothrix sensu lato (Parmeliaceae, Ascomycota)
(The American Bryological and Lichenological Society, Inc. - The Bryologist, 2015)The phylogenetic position of the monotypic genus Bulborrhizina is studied using molecular data from three loci (mtSSU, nuLSU and ITS) aligned with sequences from 95 other samples of parmelioid lichens. Bulborrhizina africana ... -
Multinomial Logit Modeling of Factors Associated With Multiple Sexual Partners from the Kenya Aids Indicator Survey 2007
(American Journal of Theoretical and Applied Statistics, 2015-05)The number of lifetime sex partners of an individual has an important effect on Human Immunodeficiency Virus (HIV) status of an individual; hence modeling multiple sexual partnerships is an essential component of any ... -
New Measurement of Antineutrino Oscillation with the Full Detector Configuration at Daya Bay
(PHYSICAL REVIEW LETTERS, 2015-05)We report a new measurement of electron antineutrino disappearance using the fully-constructed Daya Bay Reactor Neutrino Experiment. The final two of eight antineutrino detectors were installed in the summer of 2012. Including ... -
Optimal Slope Designs for Second Degree Kronecker Model Mixture Experiments
(Science publishing group, 2017)The aim of this paper is to investigate some optimal slope mixture designs in the second degree Kronecker modelbn for mixture experiments. The study is restricted to weighted centroid designs, with the second degree ... -
Phytofabrication of Iron Nanoparticles and their Catalytic Activity
(Springer Nature Switzerland AG 2019, 2019-06-20)Metallic nanoparticles that have photocatalytic activity can be synthesized using aqueous plant extracts. The aim of this study was to synthesize iron nanoparticles using Lantana trifolia extracts and to evaluate their ... -
Radiometric assessment of natural radioactivity levels around Mrima Hill, Kenya
(International Journal of the Physical Sciences, 2011-07)Mrima Hill, located in the South coast of Kenya is known for high natural background radiation, due to the presence of radiogenic heavy minerals such as monazites and carbonatites. The activity concentration of 238U, 232Th ... -
Relationship between virulence and repellency of entomopathogenic isolates of Metarhizium anisopliae and Beauveria bassiana to the termite Macrotermes michaelseni
(Journal of Insect Physiology, 2009)Termites encounter a diverse array of potentially useful and harmful fungi in their subterranean habitats. These vary from symbiotic to harmful species with varying levels of virulence. How these hemiedaphic insects survive ... -
Reproducibility of (n,γ) gamma ray spectrum in Pb under different ENDF/B releases
(Elsevier, 2016-02)Radiative capture reactions are of interest in shielding design and other fundamental research. In this study the reproducibility of (n,γ) reactions in Pb when cross-section data from different ENDF/B releases are used in ... -

Selection of promising fungal biological control agent of the western flower thrips Frankliniella occidentalis (Pergande)
(Letters of Applied Microbiology, 2012-02)Aims: Larval stages of Frankliniella occidentalis are known to be refractory to fungal infection compared with the adult stage. The objective of this study was to identify promising fungal isolate(s) for the control of ... -
Simulation of (16)O (n, p) (16)N reaction rate and nitrogen-16 inventory in a high performance light water reactor with one pass core
(Applied Radiation and Isotopes; Elsevier, 2014-12)The rate of activation of the isotope (16)O to (16)N in a typical HPLWR one pass concept was calculated using MCNP code. A mathematical model was used to track the inventory of the radioisotope (16)N in a unit mass of ... -
Species Composition, Distribution, and Seasonal Abundance of Liriomyza Leafminers (Diptera: Agromyzidae) Under Different Vegetable Production Systems and Agroecological Zones in Kenya
(Environmental Entomology, 2015-02-03)A longitudinal study to identify the species of Liriomyza leafminer, their distribution, relative abundance, and seasonal variation, including their host range, was conducted in vegetable fields at three altitudes in Kenya ... -
Synthesis and characterization of dialdehyde cellulose nanofibers from O. sativa husks
(SN Applied Sciences, 2019-06)Periodate oxidation of cellulose breaks the C2–C3 bond of the glucose repeating units forming two vicinal aldehyde groups that are amenable to further reactions. In this article, effects of reaction conditions during the ... -
