Researchers across the world have tried to explore the impact of non-Newtonian liquid flowing via an extendable surface with the inclusion of various effects due to its industrial and engineering applications like polymer production, paper production, filament extrusion from a dye, etc. This study investigates the behavior of stagnation point flow of Carreau liquid attached with inclined magnetic effect and spectral relaxation approach is utilized here for the numerical outcome. In this study, a few other vital features are attached like the quadratic multiple regression model for Nusselt number evaluation, passive control of nanoparticles, viscus heating thermophoresis, Brownian motion, and mixed convection, etc. Velocity disbursement visibility is analyzed by placing an inclined magnetic field. Physical model generates collection of partial differential equations (PDEs) and these PDEs are moved into ordinary differential equations by a similarity transformations scheme. Further for numerical process, spectral relaxation method is used. Growth in K causes a reduction in velocity because this parameter K creates the impedance to flowing resulting in confines the movement of liquid in restricted the plate. Direct relation is found between $$Ec$$
Ec
and the energy file. In the case of S > 1, physically it is a representation of Joule and viscous dissipations. This article is novel in its sense that the influence of oblique magnetic force and second order velocity slippage on Carreau nano liquid and its numerical computation with help of the spectral relaxation method has never been done before. Furthermore, the quadratic multiple regression model has been employed to find the heat transition rate in the status of the Nusselt number.
Fluid viscosity manages several engineering processes and keeps its leading role in lubrication models, biological models, polymer processes, melt solutions, colloidal suspensions, and mayonnaise. The cross viscosity model is the most appropriate model, which interprets the key features of non-Newtonian fluids in the region of shear-thinning/thickening when very high and very low shear rates are applied. This article focuses on the mathematical model of threedimensional Cross nanofluid and interprets its aspect of infinite shear rate of viscosity over the expanding sheet. Velocity is studied through placing inclined magnetic dipole effect, transportation phenomenon is brought by considering the radiation effects, heat generation and chemical process is engaged for concentration of nanoparticles. The geometry of this mathematical model is expanding the stretching sheet with velocity slip, and convective heat conditions are associated. Similarity variables are being utilized for conversion dimensional mathematical model into nondimensional one. For the pursuit of numerical solution of the system of nondimensional
Solar energy is the basic source of renewable energy, and it is being used for controlling global pollution/warming. As the Cross nanofluid is very useful for cooling solar devices, in this paper analysis of the global warming effect is investigated by incorporating the nonlinear thermal radiation over the exponentially extendable surface because it plays a major role related to solar energy absorption of nanofluid. Furthermore, the mathematical modeling of Cross nanofluid involving magnetic effect and diffusion is discussed by using the fact of chemical reaction. Chemical reaction finds astonishing applications in pollution studies, chemical processing equipment, and polymer production. As a result of this study, it is noticed that more magnetized conducting fluid controls the motion of fluids for both cases of shear thinning and shear thickening. Brownian motion parameter Nb affects the rate of the random motion of nanoparticles. Increased Nb temperature also increases due to these random movements of nanoparticles. That is the reason why pollutant nanoparticles spread in air as a result of global warming increase.
El artículo de investigación tiene como propósito establecer la relación entre el clima social familiar y el clima laboral de los trabajadores operarios de la empresa pesquera – LALA FISH E.I.R.L. - PAITA. A través del diagnóstico comparativo nos ha permitido establecer la correlación entre el clima social familiar y el clima laboral. Los datos estadísticos se consiguieron a través del proceso de las encuestas realizadas a los 180 trabajadores acerca del “clima social familiar” y “clima laboral”. Los resultados denotan que no existe relación significativa con un p≥0.05 entre el clima social familiar y el clima laboral de los trabajadores operarios de la Empresa Pesquera en estudio. Se concluye que 47.10% de los trabajadores tienen un regular clima social familiar y en efecto el clima laboral es eficiente respaldado con un 44.20%.
The current investigation explains the chemical reaction and bioconvection process for an inclined magnetized Cross nanofluid over an inclined cylinder using a spectral relaxation approach. Additionally, the facts concerning swimming gyrotactic microorganisms, non-uniform thermal conductivity, and variable decrease or increase in heat sources are taken together. Each profile is checked for inclined and orthogonal magnetic impact. Appropriate transformations made for conversion of nonlinear PDEs into systems of ODEs. For obtaining numerical results, a spectral relaxation approach is utilized, and graphs are plotted with each physical parameter attached. It is well established that the temperature field intensifies owing to an amplification of thermal conduction and Brownian diffusivity phenomena. The heat transfer rate amplifies owing to a magnification in magnetic parameter and thermal conductivity, but the velocity field diminishes as a result of magnification in the Weissenberg number and power law index. Amplification in the reaction rate constant parameter diminishes the concentration field. Activation energy is the key factor responsible for magnification in the concentration field. Furthermore, smooth agreement is found during comparison with the existing literature. Statistical analysis is also conducted for physical quantities.
El objetivo del presente estudio fue describir las actitudes que manifiestan los estudiantes universitarios de la ciudad de Piura frente a personas en situación de discapacidad en función al sexo, edad y el contacto con familiares o amigos de personas con discapacidad. Se utilizó un diseño de investigación no experimental, con enfoque cuantitativo de tipo aplicado, transversal, descriptivo comparativo. Se empleó el cuestionario: Escala de actitudes hacia las personas con discapacidad de (Verdugo et al., 1994), conformado por 37 preguntas, la cual se aplicó a una muestra de 807 estudiantes universitarios piuranos de I ciclo de las 16 carreras profesionales, de los cuales 493 son mujeres y 314 varones. Los resultados encontrados indican que los estudiantes universitarios no presentan una actitud favorable frente a las personas con discapacidad. Sin embargo, el análisis comparativo señala que las mujeres muestran actitudes más favorables que los varones, así como también los estudiantes más jóvenes en comparación con los mayores. No se encontraron diferencias significativas según tuviesen contacto o no, con familiares o amigos con alguna discapacidad, salvo en el área de valoración de capacidades y limitaciones.
