On A Class of Idealized Near-Rings Admitting Frobenius Derivations.
(Journal of Advances in Mathematics and Computer Science, 2020-07-15)In this paper, we use the idealization procedure for finite rings to construct a class of quasi-3 prime Near-Rings N with a Jordan ideal J(N) and admitting a Frobenius derivation. The structural characterization of N; J(N) ... -
On Characterization of Norm Attaining Operators in Fr´echet Spaces
(Journal of Advances in Mathematics and Computer Science, 2022-10-25)In this paper, the norm attaining operators in Fr´echet spaces are considered. These operators are characterized based on their density, normality, linearity and compactness. It is shown that the image is dense for a ... -

On the predictors of pro-environmental behaviors: integrating personal values and the 2-MEV among secondary school students in Tanzania
(Heliyon, 2022-05-03)The role of personal values in understanding pro-environmental attitudes and behaviors has received considerable attention from psychological researchers. However, little is known about the mutual interaction of personal ... -
On the Zero Divisor and Cayley Graphs of Some Classes of the 2-Radical Index of Nilpotence Finite Local Rings
(Journal of Advances in Mathematics and Computer Science, 2022-07-08)The characterization of finite local rings via the well known structures of their zero divisor graphs and cayley graphs remains an open problem. Some classes of completely primary finite rings which are local, have however ... -
Optical modelling of TCO based FTO/TiO2 multilayer thin films and simulation in hydrogenated amorphous silicon solar cell
(Scientific Africa, 2023-04-26)Hydrogenated Amorphous silicon (a:Si:H) has low amounts of defects making it attractive for photovoltaic applications. To improve power conversion efficiency (PCE) of a:Si:H solar cells, this study investigated the effect ... -
Optimal Allocation in Small Area Mean Estimation Using Stratified Sampling in the Presence of Non-Response`
(International Journal of Statistical Distributions and Applications, 2021-03-01)Sample survey provides reliable current statistics for large areas or sub-population (domains) with large sample sizes. There is a growing demand for reliable small area statistics, however, the sample sizes are ... -
Optimal efficacy in mosquito-host interaction inhibition by 35-60 kHz animal sounds for malaria control
(Biophysical Journal, 2023-02-10)Female Anopheles gambiae sensu stricto, the malaria vector, continues to develop resistance to synthetic insecticides thus threatening its control. Studies on mosquitoe's phonotaxis showed that the electronic mosquito ... -
Optimisation, validation and field applicability of a 13C-sucrose breath test to assess intestinal function in environmental enteropathy among children in resource poor settings
(Journal of Pregnancy, 2020-05)Abstract Introduction Environmental enteropathy (EE) is suspected to be a cause of growth faltering in children with sustained exposure to enteric pathogens, typically in resource-limited settings. A major hindrance to ... -
