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 ... -
A new mite IPM strategy: predator avoidance behaviour resulting from the synergetic effects of predator release and acaricide‐treated nets
(Wiley, 2018-10-26)Background: Tetranychus evansi and T. urticae spider mites are known major pests of Solanaceae. Smallholders in Africa rely heavily on pesticide treatments. However, farmers claim that pesticides are generally ineffective ... -
ON THE MAXIMAL NUMERICAL RANGEOF ELEMENTARY OPERATORS
(2017)The notion of the numerical range has been generalized in different directions. One such direction, is the maximal numerical range introduced by Stampfli (1970) to derive an identity for the norm of a derivation on L(H).Unlike ... -
Open relationships in the castles of clay: high diversity and low host specificity of Termitomyces fungi associated with fungus-growing termites in Africa
(International Union for the Study of Social Insects (IUSSI), 2010-08)In the African and Asian tropics, termites of the subfamily Macrotermitinae play a major role in the decomposition of dead plant material. Their ecological success lies in the obligate mutualism of the termites with fungi ... -
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 ... -
Performance of a semiochemical-baited autoinoculation device treated with Metarhizium anisopliae for control of Frankliniella occidentalis on French bean in field cages
(Karatina University, 2011-12-16)The performance of an autoinoculation device was evaluated in field cage experiments for control of Western flower thrips, Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae), in French bean, Phaseolus vulgaris ... -

(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 ... -
The risk of pathogenic intestinal parasite infections in Kisii Municipality, Kenya
