Due to COVID-19 pandemic, electronic learning (e-learning) has been considered as a main tool for delivering education all over the world. The study aims at identifying factors affecting students’ continued usage intention of e-learning during pandemic and mediating role student satisfaction. To achieve that, research model developed through combining Delone & McLean model, diffusion innova...

The binding of an excess electron to HBO and BOH was studied at the coupled cluster level of theory with single, double and non-iterative triple excitations and with extended basis sets to accommodate the loosely bound excess electron. The bent BOH molecule, with a dipole moment of 2.803D, binds an electron by 39 cm , whereas the linear HBO tautomer possesses a similar dipole moment (2.796D) ye...

We present a new concept for an electronically tunable diode laser. It is based on an external-cavity configuration with simultaneous feedback and intracavity spatial separation of the laser's spectral components. The electronical tunability is achieved by insertion of a liquid-crystal array as an electronically controlled aperture into the region of spatial separation of the spectral component...

Many engineering systems create unwanted noise that can be reduced by the careful application of engineering noise controls. When this noise travels down tubes and pipes, a tuned resonator can be used to muffle noise escaping from the tube. The classical examples are automobile exhaust and ventilation system noise. In these cases where a narrow frequency band of noise exists, a traditional engi...

This article considers the application of selected components of selfregulated learning (SRL; Zimmerman 2000) to student-content interaction in online learning and distance education (DE). In particular we discuss how, when interacting with electronically enhanced text, students must carefully employ self-regulated learning strategies that include planning, goal setting, self-monitoring process...
