We study the evolution of fronts in a bistable equation with time-delayed global feedback in the fast reaction and slow diffusion regime. This equation generalizes the Hodgkin-Grafstein and Allen-Cahn equations. We derive a nonlinear equation governing the motion of fronts, which includes a term with delay. In the one-dimensional case this equation is linear. We study the motion of one- and two...

Teacher education is recognized as the process of improving teaching practices. During their postgraduate studies, aspiring teachers are encouraged to improve both practice and working conditions. Therefore, an expectation for Masters’ degrees that upon graduation, they can achieve job satisfaction. This study had a quantitative approach with cross-sectional correlational non-experimental resea...

With a very long history, traditional Chinese medicine (TCM) has a rich knowledge about human health and disease by its special way. To avoid losing lots of precious knowledge of TCM masters, endeavors have been engaged to keep down those knowledge of TCM masters, such as their growth experiences, effective practical cases toward sickness and typical treating methods and principles. In this pap...
