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 ...
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 ...
Occurrence of Fungal Foliar Diseases of Tomato in Different Agro-Ecological Zones of Kirinyaga County, Kenya
(Fundamental and Applied Agriculture, 2022-03-30)
Tomato production is characterized by inconsistent quality and yields due to biotic constraints such as fungal foliar diseases. Information on the occurrence of the diseases in different agro-ecological zones of Kenya is ...
Aspects of The Biology and Population Structure of Oreochromis Niloticus, Coptodon Zillii and Oreochromis Leucostictus Tilapia in Lake Naivasha, Kenya
(2022-03-03)
The Nile tilapia (Oreochromis niloticus), Redbelly tilapia (Coptodon zillii) and Blue spotted tilapia (Oreochromis leucostictus) were introduced into Lake Naivasha in the 1950s to diversify and boost the lake fisheries. ...
Implementation of Technology and Innovation Support Centers (Tiscs) in Kenya: Challenges and Opportunities
(Elsevier, 2022-02)
Technology and Innovation Support Centers (TISCs) were established by the World Intellectual Property Organization (WIPO) in 2009 to support innovations in least developed countries. They facilitate innovators to access ...
Analysis of an Arterial Pulse Using 1D KdV Model
(IRE Journals, 2022-01)
In this study we developed a soliton model of an arterial pulse. The Korteweg-de Vries wave equation is our model of interest. It incorporates the aspect of modeling an arterial pulse which can potentially lead to development ...
Completely Positive Map from M4(C) to M5(C) on Positive Semidefinite Matrices
(Journal of Mathematical Analysis and Modeling, 3/29/2022)
Positive Maps Are Essential In the Description of Quantum Systems. However, Characterization Of The Structure Of The Set Of All Positive Maps Is A Challenge In Mathematics And Mathematical Physics. We Construct A Linear ...
On Equality of Complete Positivity and Complete Copositivity of Positive Map
(Journal of Linear and Topological Algebra, 5/30/2022)
In this paper we construct a 2-positive map from M4(C) to M5(C) and state the
conditions under which the map is positive and completely positive (copositivity of positive).
The construction allows us to create a decomposable ...
