Effect of pH, Carbon and Nitrogen Sources on Antibiotic Production by Actinomycetes Isolates from River Tana and Lake Elementaita, Kenya
(Asian Journal of Research in Biochemistry, 2023-08-04)The escalating concern over antibiotic resistance and its profound impact on public health have underscored the urgent need to explore alternative reservoirs of antimicrobial agents. In this regard, Actinomycetes have ... -
Characterization of Antibioticproducing Actinomycetes Isolated from River Tana and Lake Elementaita in Kenya
(Asian Journal of Research in Biochemistry, 2023-08-01)The rise of antibiotic-resistant bacteria has become a global health concern, necessitating the search for novel sources of antibiotics. Actinomycetes, a group of microorganisms, have been known for their ability to ... -
A NOTE ON QUASI-SIMILARITY OF OPERATORS IN HILBERT SPACES
(International Journal of Mathematical Archive, 2015-07-23)In this paper we introduce the notion of Quasi-similarity of bounded linear operators in Hilbert Spaces. We do so by defining a quasi- affinity from one Hilbert Space H to K. Some results on quasi- affinities are also ... -
Polylactic acid (PLA) viscoelastic properties and their degradation compared with those of polyethylene
(Academic Journals, 2015-10-19)Polyethylene (PE) films are widely used in packaging. PE is a thermoplastic manufactured from nonrenewable petroleum resources. Due to its non–biodegradability, its films have posed serious pollution problems e.g. visual ... -
Molecular characterization of wood ear mushrooms [Auricularia sp.] from Kakamega Forest in Western Kenya
(Current Research in Environmental & Applied Mycology, 2016-03-30)Mushrooms of the genus Auricularia, generally termed wood ear mushrooms are in high demand in Western Kenya due to their numerous medicinal and nutritional properties. Interventions to characterize and conserve the native ... -
Concentration of Inorganic Contaminants in Shallow Borehole Water in Chuka Sub-County, Kenya
(Journal of Chemical, Biological and Physical Sciences, 2020-11-24)Groundwater from shallow aquifers is an important source of portable water in Chuka Sub-County. However, most shallow boreholes in Chuka Sub-County are undocumented and susceptible to contamination by both geogenic and ... -

Massive Protocluster of a Periodic Maser Source G188.95+0.89
(Oxford University Press on behalf of Royal Astronomical Society, 2021-07-14)We report the results of ongoing monitoring of the 6.7 GHz CH3OH masers associated with G188.95+0.89. In these observations, five features are periodically varying and at least two exhibit evidence of velocity drifts. It ... -
Status of Plasmodium Falciparum Resistance to Sulfadoxine Pyrimethamine in Kwale County, Kenya
(Epidemiology International, 2019-12)Background: Malaria persists to be one of the major significant diseases in the world. A range of antimalarial drugs are readily accessible but management of the disease remains a problem. Despite the broadened spread ... -
Thermal Conductivities of Selected Solid Waste Materials Determined Using Lees’ Disc Method
(International Journal of Research Publications (IJRP.ORG), 2020-04-02)In this study, the coefficients of thermal conductivities have been determined. The goal was to find out the best insulator among the recyclable and locally available materials which can be adopted for use to replace the ... -
Calorific Value and Moisture Content Of Selected Solid Wastes at Chuka University
(IJRP.ORG., 2020-04-02)Solid waste, which typically consists of metals, plastics, glasses, paper, wood, and organics, is generated and accumulated due to human day to day activities. The waste often leads to ecological pollution unless an ... -
The Banach Numerical Range for Finite Linear Operators

Correlation Between Electromagnetic Wave Equation And Einstein Theory Of Relativity In Derivation Of Schrödinger Equation And Hilbert Space Operators
(Journal of Multidisciplinary Engineering Science Studies (JMESS), 2020-03)Operators in Hilbert space have properties which are useful in the study of mathematical abstract areas such as approximation theory, Banach Fixed point theory, the spectral theory as well as Quantum Mechanics. ... -
Food Rheology using Dynamic Mechanical Analysis; A short review
(Paul Kamweru, 2020-02)An ideal elastic material will deform finitely and recover its original shape and size upon the removal of the applied deforming load. On the other hand an ideal fluid will deform and continue to deform as long as the ... -
PLS Generalized Linear Regression and Kernel Multilogit Algorithm (KMA) for Microarray Data Classification Problem
(Revista Colombiana de Estadística - Applied Statistics, 2020)This study involves the implentation of the extensions of the partial least squares generalized linear regression (PLSGLR) by combining it with logistic regression and linear discriminant analysis, to get a partial least ... -
A likelihood ratio test for correlated paired multivariate samples
(Chilean Statistical Society, 2020-04)Many laboratory experiments in the fields of biological sciences usually involve two main groups say the healthy and infected subjects. In one of these kind of experiments, each specimen from each group can be divided ... -
