Ohmic heating and chemical reaction effect on MHD flow of micropolar fluid past a stretching surface

Abstract: The current article discuss the interaction between the Ohmic heating and chemical reaction impact on MHD micropolar fluid flow past a stretching surface in the existence of chemical reaction using Runge–Kutta–Fehlberg method (RKF-45) along with the shooting procedure. By applying some similarity transformations, the governing equations were changed to ODEs. Numerical consequences were calculated for many values of pertinent factors on flow, angular velocity, thermal, mass transfer are exposed graphically and the numerical outcomes of the skin friction, couple stress at the wall, Nusselt number, Sherwood number are entered in tabulated form. With an increase of the material parameter, the velocity, couple stress, Sherwood number, Nusselt number, and temperature, concentration, and shear stress increase, while temperature, concentration, and shear stress decreases.

Role of Perceived Organizational Support in the Relationship between HR Practices and Organizational Trust

Abstract: This article examines the role of perceived organizational support as a mediator in the relationship between human resources practices and organizational trust. Analysis of data from a sample of 308 employees from various Indian companies located in the National Capital Region (NCR) indicated that perceived organizational support significantly but partially mediates the relationship between human resource practices and trust in the organization.

Optical spectroscopy and energy transfer in Tm^3^+-doped metaphosphate laser glasses

Abstract: Thulium-doped metaphosphate glasses with four concentrations (0.01, 0.1, 1.0 and 2.0 mol%) of Tm 3+ have been prepared and investigated by Raman, absorption and photoluminescence spectral studies. The phonon sideband spectrum has been measured for 1.0 mol% Eu 3+ -doped metaphosphate glass of the same composition and compared with the Raman spectrum. From vibronic spectra, various bands associated with different structural groups have been identified and assigned. Absorption band positions have been used to simulate the complete energ yl evel diagram for the Tm 3+ ion using the model Hamiltonian. Judd–Ofelt parameters have been determined from the absorption bands .U sing these parameters, transition probabilities, excited state lifetimes and transition branching ratios have been evaluated. The emission and decay curves of the 1 D2 level have been measured for all four glass samples both at RT and 15 K. Lifetimes show a strong quenching for Tm 3+ concentrations higher than 0.1 mol%. Fluorescence decay curves of the 1 D2 level have been well fitted to th eI nokuti–Hirayama model for S = 6, suggesting that the mechanism for energy transfer between Tm 3+ ions is of dipole–dipole type.
