Darcy-Forchheimer hybrid nanofluid flow over a stretching curved surface with heat and mass transfer.

The present article provides a detailed analysis of the Darcy Forchheimer flow of hybrid nanoliquid past an exponentially extending curved surface. In the porous space, the viscous fluid is expressed by Darcy-Forchheimer. The cylindrical shaped carbon nanotubes (SWCNTs and MWCNTs) and Fe3O4 (iron oxide) are used to synthesize hybrid nanofluid. At first, the appropriate similarity transformation is used to convert the modeled nonlinear coupled partial differential equations into nonlinear coupled ordinary differential equations. Then the resulting highly nonlinear coupled ordinary differential equations are analytically solved by the utilization of the "Homotopy analysis method" (HAM) method. The influence of sundry flow factors on velocity, temperature, and concentration profile are sketched and briefly discussed. The enhancement in both volume fraction parameter and curvature parameter k results in raises of the velocity profile. The uses of both Fe3O4 and CNTs nanoparticles are expressively improving the thermophysical properties of the base fluid. Apart from this, the numerical values of some physical quantities such as skin friction coefficients, local Nusselt number, and Sherwood number for the variation of the values of pertinent parameters are displayed in tabular forms. The obtained results show that the hybrid nanofluid enhances the heat transfer rate 2.21%, 2.1%, and 2.3% using the MWCNTs, SWCNTs, and Fe3O4 nanomaterials.

Unique contextual conditions affecting coworker knowledge sharing and employee innovative work behaviors / Las condiciones contextuales singulares que afectan al intercambio de conocimientos entre los trabajadores y a los comportamientos laborales innovadores

Apoyándose en el modelo de componentes de creatividad, este estudio analiza de qué manera el intercambio de conocimientos entre los empleados produce comportamientos laborales innovadores en el trabajo. También se analiza el efecto moderador del factor situacional (intercambio de conocimientos de los supervisores) y del factor personal (progreso de los empleados) con el fin de explorar las condiciones contextuales singulares que pueden afectar a esta relación. Se dispuso de una muestra de 374 empleados de distintos puestos y sectores para poner a prueba estas relaciones. Se planteó la hipótesis de que el intercambio de conocimientos de los supervisores se desdibujaría mientras que el progreso de los empleados en el trabajo fortalecería la relación positiva entre el intercambio de conocimientos de los trabajadores y los comportamientos innovadores. Confirmaron estas supuestas relaciones los resultados de la regresión múltiple, gráficos y análisis de pendientes. Se abordan las implicaciones teóricas que puede conllevar para el comportamiento innovador en el trabajo

Drawing on a componential model of creativity, this study examines how coworker knowledge sharing drives employee innovative work behaviors in the workplace. Furthermore, the moderating effect of situational factor (supervisor knowledge sharing) and personal factor (employee thriving) were analyzed to explore the unique contextual conditions which could influence this relationship. A sample of 374 employees across a variety of jobs and industries was used to test these relationships. Supervisor knowledge sharing was hypothesized to dampen, while employee thriving at workplace was hypothesized to strengthen the positive relationship between coworker knowledge sharing and employee innovative work behaviors. Results of the hierarchal multiple regression, plots, and slope analysis confirmed the hypothesized relationships. The theoretical and practical implications for employee innovative work behavior at work are discussed
