We consider the Dirac equation with two different four-potentials of the plane electromagnetic waves. We derive the partial differential equation for the wave function, which is generalized form of the Volkov equation. We find the solutions of the Dirac equation for two orthogonal plane waves. We determine the modified Compton formula for the scattering of two photons on an electron.
In this paper, the heat balance of an engine was investigated experimentally. The experimental work was conducted on the EF7 natural gas fueled and turbocharged engine. The main goal was to develop an empirical equation to be able to predict the heat balance of the engine at various loads and conditions. The data were collected at four different conditions, two different loads and two differ...
the major purpose of this study was to develop the translation teacher competency test (ttct) and examine its construct and predictive validity. the present study was conducted in two phases: a qualitative phase as well as a quantitative phase. in the first phase of the study, the author attempted to find out the major areas of competency required for an academic translation teacher. the second...
