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 ...
The Role of Acid Concentration on Band Gap Shrinkage in Cellulose Nanocrystals Fabricated from Water Hyacinth
(Journal of Material Sciences & Manufacturing Research, 2022-01-05)
In this study, the fingerprint of the acid concentration during the hydrolysis process on the optical band gap of cellulose nanocrystals (CNCs) has been systematically studied. The CNCs have been prepared using hydrochloric ...
Persistent Low Level Viraemia in Antiretroviral Treated Patients: Associated Factors and Virologic Outcome among HIV-1 Infected Patients at Nyakach County Hospital
(Global Scientific Journals, 2022-02)
Antiretroviral treatment (ART) assists patients in controlling their HIV
infection and ensuring long-term survival. Despite this advantage, a significant number
of HIV-positive individuals do not attain full virologic ...
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 ...
Factors that Influence Adoption of New Improved Wheat Varieties by Farmers in Nakuru and Narok, Kenya
(European Journal of Agriculture & Food Science, 2022-04-14)
This study examines the factors that influence the adoption of new improved wheat varieties (NIWV) by wheat farmers in Nakuru and Narok counties in Kenya. Cross-sectional data from 344 randomly selected wheat farmers from ...
Biogenically Synthesized Silver/Gold Nanoparticles, Mechanism and their Applications: A Review
(Asian Journal of Chemical Sciences, 2022-02-28)
As a result of climate change and rapid urbanization, attention increasingly turns to the management of water resources. Proper management of water resources has become a core concern for development practitioners and ...
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 ...
