On (n, m)-Metrically Equivalent Operators
(International Journal of Mathematics And its Applications, 2021)In this paper, we introduce the class of (n,m)-metrically equivalent operators which is a generilazation of metrically equivalent operators and n-metrically equivalent operators. We then look at some properties of this ... -
On class (n, mBQ) Operators
(World Journal of Advanced Research and Reviews, 2021-06-26)In this paper, we introduce the class of (n, mBQ) operators acting on a complex Hilbert space H. An operator if T ∈ B (H) is said to belong to class (n, mBQ) if T ∗2mT 2n commutes with (T ∗mTn ) 2 equivalently [T ∗2mT 2n, ... -
On N-A-Metrically Equivalent and A-Metrically Equivalent Operators
(International Journal of Mathematics And its Applications, 2021)A-metrically equivalent operators may be regarded as a generalization of metrically equivalent operators. This is realized when A= I and T ]= T ∗ . Definition 1.1. Two operators S ∈ BA(H) and T ∈ BA(H) are said to ... -
On Numerical Range of Multiplication Operator
(International Journal of Mathematical Analysis, 2019)Let H be an infinite dimensional complex Hilbert space and A, B ∈ B(H) where B(H) is the C ∗ -algebra of all bounded linear operators on H. Let MAB : B(H) → B(H) be a multiplication operator induced by A and B defined ... -
On Skew Class (BQ) Operators
(Iconic Research and Engineering Journals, 2022-12)The class of Skew (BQ) operators acting complex Hilbert on an separable H is introduced in this paper. An operator if K ∈L (H) is said to belong to class Skew (BQ) if K commutes with a (BQ) operator, that ... -
Parameterized Empirical Potentials For BaF2 From Ab-Initio Methods Applied To The Study Of Superionic Transition Of C-BaF2
(Journal of Multidisciplinary Engineering Science and Technology (JMEST), 2018)Potentials for BaF2 have been generated from the ab-initio methods and tested to determine its applicability in classical dynamics. The minimization process for this force field was stopped at 17% where forces, ... -

Performance of CSTR–EGSB–SBR system for treating sulfate-rich cellulosic ethanol wastewater and microbial community analysis
(2017)Performance and microbial community composition were evaluated in a two-phase anaerobic and aerobic system treating sulfate-rich cellulosic ethanol wastewater (CEW). The system was operated at five different chemical ... -
Phylogenetic relationship among Kenyan sorghum germplasms based on aluminium tolerance
(2015-08-21)Eighty nine (89) sorghum lines sourced from various parts of Kenya were used to determine phylogenetic relationships based on 10 DNA fragments at AltSB loci with SbMATE, ORF9 and MITE primers. Nine lines of varying ... -
Physiological characterization of kenyan sorghum lines for tolerance to aluminium
(2015-08-21)Eighty nine Kenyan sorghum lines were screened for tolerance to aluminium toxicity in nutrient solution. Relative net root growth; root tip aluminium content and variation in organic acid exudation were used to determine ... -
