On Compact Operators Whose Norms Are Eigenvalues and Completeness
(International Journal of Contemporary Mathematical Sciences, 2/21/2018)Let X be a Banach space and T: X→Y be a linear operator, then Tis compact if it maps bounded sequences in X to sequences in Y with convergent subsequences, that is, if xn ∈ X is a bounded sequence, then T xn ∈ Y has a ... -
On denseness of similarity orbits of norm-attainable operators
(International Journal of Advances in Applied Mathematics and Mechanics, 4/16/2019)The notion of dense sets has been extensively discussed on both metric and topological spaces. Various properties of the sets have been proved under the underlying spaces. However, if we consider these sets to be from ... -
International Journal of Statistics and Applied Mathematics 2018; 3(4): 74-84 Reconstructing earth observation vegetation index records with a Bayesian spatiotemporal dynamic model
(International Journal of Statistics and Applied Mathematics, 2018-01)Long-term vegetation index records derived from Earth observation facilitate the characterization of ecosystem response to climate variability and change. The presence of atmospheric components and radiometric inconsistencies ... -
Choi Matrices of 2-positive Maps on Positive Semidefinite Matrices
(Asian Research Journal of Mathematics, 4/27/2020)Several investigations have been done on positive maps on their algebraic structures with more emphasis on completely positive maps. In this study we have described the structure of the Choi matrices for 2−positive maps ... -
On Compactness of Similarity Orbits of Norm-Attainable Operators
(International Journal of Mathematics And its Applications, 2019)The notion of compactness plays an important role in analysis. It has been extensively discussed on both metric and topological spaces. Various properties of compactness have been proved under the underlying spaces. However, ... -
On Characterization of Very Rotund Banach Spaces
(International Journal of Modern Computation, Information and Communication Technology, 10/23/2018)It is known that the Hilbert space H is the most rotund space among all Banach spaces. The question whether if a normed space X is a rotund Banach space implies we can obtain other most rotund spaces is still open and ... -
Bayesian Estimation of Probability of Contamination under Group Screening Design
(Bulletin of Mathematics and Statistics Research, 2018-07)In health area the prevalence rate p is considered to be a fraction that show positive results out of the entire sampled population when tests are done to establish infection of a disease. Tests can be done on individual ... -
Numerical Analysis of Mathematical Model for Carbon Pollution in Roads with Ventilated Embankments in Absence and Presence of Forced Convection
(International Journal of Multidisciplinary Sciences and Engineering, 2018-11)In this paper, a two-dimensional grid based numerical carbon pollution model for the estimation of carbon pollutant concentrations in roads is developed. The simulations of carbon pollutants in roads with ventilated ... -
Mathematical Analysis of Carbon Pollution in Roads with Ventilated Embankments using Godunov FVM
(International Journal of Engineering and Mathematical Sciences, 2018-06)Kenyan Road transport currently accounts for about 78% of the total carbon emission in the country, a percentage that is lately and steadily rising causing enormous scientific concern. Consequently, efficient road design ... -
The effect of varying the capping agent of magnetic/luminescent Fe3O4–InP/ZnSe core–shell nanocomposite
(ELSEVIER, 2016-01)Magnetic–luminescent nanoparticles have shown great promise in various biomedical applications namely: contrast agents for magnetic resonance imaging, multifunctional drug carrier system, magnetic separation of cells, cell ... -
2-Hydroxy-4-Methoxybenzaldehyde: larvicidal structure-activity studies
(Chemical Society of Ethiopia, 2005)2-Hydroxy-4-methoxybenzaldehyde (1), a compound isolated from Mondia whytei (Hook) Skeels (Asclepiaceae) roots exhibited larvicidal activity (LD5022 mg/mL). A total of 18 other derivatives and closely related congeners ... -
Development, characterization and antimalarial efficacy of dihydroartemisinin loaded solid lipid nanoparticles
(ELSEVIER, 2016-04)Effective use of dihydroartemisinin (DHA) is limited by poor water-solubility, poor pharmacokinetic profile and unsatisfactory clinical outcome especially in monotherapy. To reduce such limitations, we reformulated DHA ... -
Preparation, characterization, and optimization of primaquine-loaded solid lipid nanoparticles
(PMC, 2014-08-11)Primaquine (PQ) is one of the most widely used antimalarial drugs and is the only available drug that combats the relapsing form of malaria. PQ use in higher doses is limited by severe tissue toxicity including hematological- ... -
Diagnosis and Management of Early-Onset Neonatal Sepsis (Eos) Among High-Risk Neonates in Kisii Teaching and Referral Hospital and Homabay County Referral Hospital, Western Kenya
(Clinical and Medical Case Reports, 2018)Neonatal sepsis (NS) is the third most common contributor to neonatal deaths worldwide, the majority of which occur within the first 72 hours of life (Early-onset sepsis [(EOS)]). Diagnosis of EOS is challenging due to ... -
Comparison of the ratio estimate to the local linear polynomial estimate of finite population totals
(IJESM, 2013-03)In this paper, attempt to study effects of extreme observations on two estimators of finite population total theoretically and by simulation is made. We compare the ratio estimate with the local linear polynomial estimate ... -
Effects of outliers on estimation of finite population totals
(2013-06)In this paper, attempt to study effects of outliers on two estimators of finite population total theoretically and by simulation is made. We compare the ratio estimate with the local linear polynomial estimate of finite ... -
Deterministic mathematical model for fish harvesting
(INTERNATIONAL JOURNAL OF ENGINEERING SCIENCES & RESEARCH TECHNOLOGY, 2015)Differential equations have been used to create mathematical models of real world systems in which rates of change are involved, for example in the study of how population grows or shrinks. One of the earliest models by ... -
Socio-economic factors influencing the spread of drinking water diseases in rural Africa: case study of Bondo sub-county, Kenya
(IWA Publishing, 2015)Socio-economic and medical information on Bondo sub-county community was studied to help establish the relationship between the water quality challenges, community health and water rights conditions. Health challenges have ... -
