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 ... -
