Mental health through forgiveness: Exploring the roots and benefits

Abstract: Forgiveness is conceptualized as the process of making peace with life. The three sources of forgiveness, another person, oneself, and a situation or circumstance are capable of freeing a person from a negative association to the source that has transgressed against a person. Research studies show the mental health benefits associated with forgiveness. The present study explores the experiences of adults who practice forgiveness, specifically, the indicators of forgiveness, the childhood antecedents, and the benefits of forgiving behavior. The study uses a qualitative research approach following a phenomenological framework. A total of 12 adults, ranging from 25 to 40 years of age, who received a high score on Heartland Forgiveness Scale were included in the study. Using semi-structured in-depth interviews, their personal experiences were explored. The data were analyzed using thematic analysis. The themes emerged show that the childhood antecedents of forgiveness are parental influences and early...

Significance of thickness of paraboloid of revolution and buoyancy forces on the dynamics of Erying-Powell fluid subject to equal diffusivity kind of quartic autocatalysis

Abstract: The flows of non-Newtonian fluid over upper horizontal surfaces of rockets, over bonnets of cars, and pointed surfaces of aircraft are of great importance to the experts in the field of space sciences, automobile construction, and aerodynamic industry where efficiency is dependent on the thickness of paraboloid of revolution, buoyancy, and autocatalysis. The purpose of this study is to present not only the nonlinear governing equation which models the transport phenomenon, but also to analyze the non-Newtonian Erying–Powell fluid flow within a thin layer formed on an object which is neither a perfect horizontal nor a vertical, and neither an inclined surface nor a cone/wedge. The governing equation suitable to model the transport phenomenon above for the case of equal diffusivity during quartic autocatalytic kind of chemical reaction was non-dimensionalized and solved numerically. The velocity of the flow along x − direction can be enhanced when thickness increases negligible but buoyancy forces increase significantly. The rate of increase in the velocity of the flow along the y − direction from the wall to the free stream is optimal when the thickness of the paraboloid of revolution is zero (objects with a uniform thickness) and buoyancy force is sufficiently large. The concentration of Erying–Powell fluid at the wall G ( 0 ) is a decreasing function of Prandtl number but an increasing property of Schmidt number.

A study of the natural convection of water-AA7075 nanoliquids in low-porosity cylindrical annuli using a local thermal non-equilibrium model

Abstract: Natural convection in nanoliquid-saturated porous cylindrical annuli due to uniform heat and mass influxes from the solid cylinder and effluxes from the outer hollow cylinder is investigated analytically. The Darcy model and the modified version of the Buongiorno two-phase model are used, and local thermal non-equilibrium between the phases is assumed. A nanoliquid-saturated porous medium made up of glass balls with a dilute concentration of AA7075 alloy nanoparticles well-dispersed in water is considered. Out of three types of annuli considered, shallow annuli provide the best heat transport and tall annuli show the worst performance. The presence of a dilute concentration of nanoparticles significantly enhances the heat transport in the system. Of nine nanoparticle shapes considered, lamina-shaped nanoparticles enhance heat transport the most. Heat transport is enhanced in the case of heat-and-mass-driven convection compared to the case of purely heat-driven convection. The results for a rectangular enclosure are obtained as a particular case of the present study. Two asymptotic routes that take us to the results of thermal equilibrium are shown. The vanishing limit of the concentration Rayleigh number yields the result for a single-phase model. Results for the base-liquid-saturated porous medium form a limiting case of the present study. We conclude that a shallow cylindrical annulus saturated with water-AA7075 lamina-shaped alloy nanoparticles is best suited for heat transfer due to its high effective thermal conductivity in comparison with that of other shaped nanoparticles and a tall rectangular enclosure saturated by water is best suited for heat storage applications.
