Influence of recognition schemes on employee performance in large commercial banks in Nairobi city county in Kenya.
(Journal of Human Resource & Leadership, 2018)Recognizing excellent performance openly builds motivation within the entire organization. It is acknowledged that employee recognition has contagious effects. When an employee witnesses others being rewarded for good ... -
Influences of Ga Doping on Crystal Structure and Polarimetric Pattern of SHG in ZnO Nanofilms
(Nanomaterials, 2019-06-21)The second-harmonic generation (SHG) in gallium doped ZnO (GZO) nanofilms was studied. The Ga doping in GZO nanofilms influenced the crystal structure of the films, which affected SHG characteristics of the nanofilms. ... -
Influences of Ga doping on crystal structure and polarimetric pattern of SHG in ZnO nanofilms
(Multidisciplinary Digital Publishing Institute, 2019)The second-harmonic generation (SHG) in gallium doped ZnO (GZO) nanofilms was studied. The Ga doping in GZO nanofilms influenced the crystal structure of the films, which affected SHG characteristics of the nanofilms. In ... -
Inhibition of proinflammatory biomarkers in THP1 macrophages by polyphenols derived from chamomile, meadowsweet and willow bark.
(John Wiley & Sons, Ltd., 2013)Antiinflammatory compounds in the diet can alleviate excessive in flammation, a factor in the pathogenesis of common diseases such as rheumatoid arthritis, atherosclerosis and diabetes. This study examined three European ... -
Interferometry Analysis of Cellophane Birefringence
(Optics and Photonics Journal, 2013-10)This paper reports on a simple approach of determining the ability of a transparent material, such as cellophane to rotate the direction of polarization of a light beam. In order to determine the birefringence of such a ... -

Isolation of Haloalkaliphilic Fungi from Lake Magadi in Kenya
(Heliyon, 2020)In this study we explored the cultivable fungal diversity in Lake Magadi and their secondary metabolite production. Isolation was done on alkaline media (Potato dextrose agar, Malt extract agar, Oatmeal agar and Sabouraud ... -

Longitudinal Survey, Nonmonotone, Nonresponse, Imputation, Nonparametric Regression
(Scientific Research Publishing, 2016)The study focuses on the imputation for the longitudinal survey data which often has nonignorable nonrespondents. Local linear regression is used to impute the missing values and then the estimation of the time-dependent ... -
Material Properties of RE-Doped Ln (Ln= Y, La) oxides and oxysulfides phosphors for red-emitting devices
(University of the Free State, 2015)Structural and optical properties of Eu3+-doped Ln (Ln=Y, La) oxide and oxysulfide nano crystals synthesized by sol-combustion method were analysed as a function of host to fuel ratio. Structural characterization shows ... -
Modeling of COVID-19 Transmission under Markov Chains in Uganda
(Hill Publishing, 2022)In this research study, we have modeled the transmission of COVID-19 in Uganda using a discrete-time Markov chain. Most of the already used epidemiological or infectious disease transmission models consist of partial ... -
Modelling Miraa Addiction like a Disease Incorporating Voluntary Quitting
(Journal of Advances in Mathematics and Computer Science, 2017)This study presented a deterministic model of miraa addiction based on three compartmental classes incorporating miraaspecific attributes as well as the aspect of voluntary quitting. Our model was based on SIS ... -
Modelling the volatility of exchange rates in the Kenyan market
(Academic Journals, 2010)This paper considers the application of the generalized autoregressive conditional heteroscedasticity process in the estimation of volatility in the Kenyan exchange rates. A quasi-maximum likelihood estimation procedure ... -
Molecular data show that Hypotrachyna sorocheila (Parmeliaceae) is not monophyletic
(The American Bryological and Lichenological Society, Inc, 2016)Lichens that reproduce by means of vegetative propagules (soredia or isidia) are generally thought to have broad geographic distributions. However, recent studies have shown that some asexually reproducing lichens with ... -
A molecular phylogenetic reappraisal of the Hysteriaceae, Mytilinidiaceae and Gloniaceae (Pleosporomycetidae, Dothideomycetes) with keys to world species.
(PubMed, 2009)A reappraisal of the phylogenetic integrity of bitunicate ascomycete fungi belonging to or previously affiliated with the Hysteriaceae, Mytilinidiaceae, Gloniaceae and Patellariaceae is presented, based on an analysis of ... -
Molecular phylogenetic studies unmask overlooked diversity in the tropical lichenized fungal genus Bulbothrix s.l. (Parmeliaceae, Ascomycota)
(Botanical Journal of the Linnean Society, 2017)Species boundaries in lichen-forming fungi occurring in extra-tropical regions are relatively well studied in comparison with those in species distributed in tropical regions. Here, we aim to re-examine species boundaries ... -
The monotypic genus Bulborrhizina belongs to Bulbothrix sensu lato (Parmeliaceae, Ascomycota)
(The American Bryological and Lichenological Society, Inc., 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 ... -
Multigene phylogeny of the Coronophorales (ascomycota): morphology and new species in the order.
(PubMed, 2009)The phylogenetic relationships within Coronophorales have been debated because of uncertainty over the taxonomic usefulness of characterisitics such as quellkörper, number of ascospore appendages, presence of subiculum and ... -
A Multiplicative Bias Correction for Nonparametric Approach and the Two Sample Problem in Sample Survey
