In this study, the impacts of TD on the energy spectra and thermal properties of LiH, TiC and I2 diatomic molecules is considered. The Schrodinger equation in cosmic string spacetime is solved with the generalized Morse potential using the well-known (NU) method. The energy spectra and eigenfunction are obtained respectively. The energy spectra is used to obtain the partition function which is then used to evaluate the thermal properties of the system is evaluated accordingly. We find that the energy spectra in the presence of the TD differ from their flat Minkowski spacetime analogue. The effects of the deformation parameter and TD on the thermal properties of the system is also analysed in detail. We observe that the specific heat capacity of the system tends to exhibit quasi-saturation as the deformation parameter and topological defect approaches unity. The results of our study can be applied in the astrophysical situation where these modifications exist in the understanding of spectroscopical data and it may be used as a probe of the presence of a cosmic string or a global monopole in the Universe.
We discussed in this paper a fractional model arising in flow of three different incompatible fluids through a porous medium with mean microtubule pressure. The method adopted for obtaining the solution is the regular perturbation technique for the analytical solution and for the transformation of the boundary conditions. The results are in decent agreement with the findings of researched work reviewed in this paper.
In this study, the electrical conductivity and physical properties of loamy soil samples with various additives is determined. The electrical conductivity meter was used to obtain the electrical conductivity and some standard methods have been adopted to obtain other properties. It is observed that the soil combined with NPK had the highest electrical conductivity with the least coming from the soil (control). It is concluded that NPK raises the electrical conductivity of the soil. This goes forth to show a measure of the amount of salts in soil (salinity of soil), which is an important indicator of soil health. It affects crop yields, crop suitability, plant nutrient availability, and activity of soil microorganisms which in turn influences key soil processes including the emission of greenhouse gases such as nitrogen oxides, methane, and carbon dioxide. It is recommended that soil with organic manure should be used in order to maintain low salinity and good soil health.
The results were obtained graphically with coding in Mathematica. Computational work was carried out for sufficient ranges of parameters of the study namely Schmidt, Radiation, Prandtl, Heat function , Micropolar , Microrotational , Grashof s, Modified Grashofs number , Electroconductivity, Magnetic field term, Chemical potential. The effects of these parameters on the physical quantities like the Nusselt, Skin-friction coefficient , Sherwood , Velocity, Angular velocity, Energy and Concentration profile are all presented graphically. We noticed that the energy profile decreases when the Prandtl number is increased for heat source but increases for the heat sink. The Schmidt and the chemical potential behave the same way for both concentration profile and Sherwood profile. For the electroconductivity and the magnetic field term when they have increased the velocity, and the skin friction profile decreases this shows that they both acts as an opposition to the flow of the fluid.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
