Mathematical Modelling of the COVID-19 Pandemic with Demographic Effects
(Springer Nature, 2021-03-17)
In this paper, a latent infection susceptible–exposed–infectious–recovered model with demographic efects is used to understand the dynamics of the COVID-19 pandemics. We calculate the basic reproduction number (R0) by ...
On Centre Properties of Irreducible Subalgebras of Compact Elementary Operators
(doi:10.30538/psrp-oma2020.0065, 2020)
In this paper, we characterize the centre of dense irreducible subalgebras of compact elementary operators that are spectrally bounded. We show that the centre is a unital, irreducible and commutative C∗ -subalgebra. ...
The Role of Bio-Extracted Reduced Graphene Oxide in the Crystallization Kinetics of Chitosan Bio-Polymer
(Scientific research and community, 2021-01-29)
Carbon nanomaterials have recently attracted wide scientific applications due to their tunable properties. These novel materials act as best fillers that can provide substantial benefits due to their high strength, thermal ...
Properties of Spectrally Bounded Compact Elementary Operators
(DOI: 10.47443/cm.2021.0012, 2021-03-31)
Spectrally bounded compact elementary operators on dense irreducible subalgebras of C ∗ -algebras are characterized. Also, it is shown that left multiplications, right multiplications, generalized derivations and basic ...
Sensitivity Analyses of Population Projection Matrix of Cestrum Aurantiacum
(Kenya Forestry Research Institute/Jaramogi Oginga Odinga University of science and Technology., 2020)
The Lefkovitch stage specific matrix population models are divided into discrete stage classes defined by a growth variable such as size, height and diameter at breast height for trees. In matrix model, the deterministic ...
Extensions of Lefkovitch Matrix for Modeling Invasive Cestrum Aurantiacum Population Dynamics
(KEFRI/, Jaramogi Oginga Odinga University of science and Technology., 2020)
Modeling of invasive species using stage based matrix methods can be exploited to understand population dynamics of plants using stage based Leftkovitch matrix models. This study reviewed and extended the stage based matrix ...
Using organic wastes as feed substrates for black soldier fly larvae
(Wegeningen Academic Publishers, 2021-08-25)
Feeding black soldier fly larvae (BSFL) on locally available organic wastes has the potential of providing an alternative source of protein to fishmeal and soybean used in animal feed formulation. This can also mitigate ...
Use of Semiochemicals for Surveillance and Control of Hematophagous Insects
(Chemoecology, 2020-06-23)
Reliance on broad-spectrum insecticides and chemotherapeutic agents to control hematophagous insect vectors, and their related diseases is threatened by increasing insecticide and drug resistance, respectively. Thus, ...
Sweet Potato Leaf Spot Diseases and Farmer’s Indigenous Knowledge in Parts of Western Kenya
(International Journal of Research Studies in Agricultural Sciences (IJRSAS), 2021-11)
Sweet potato (Ipomoea batatas L.) is a starchy, tuberous root with worldwide consumption.
Production of sweet potatoes in Kenya is low due to disease constraints, such as fungal sweet potato leaf spot (SPLS), which is not ...
Evaluation of CO2 in Saline Aquifers under Deep Ground Water Systems in Urumqi River Basin of Xinjiang, China
(Ecological Engineering & Environmental Technology, 2021-09-17)
The future emissions of carbon dioxide (CO2) are likely to increase beyond the current levels due to rapid industrialization in China. Several methods have been proposed as possible mitigation strategies to reduce the ...
