In this paper, the high-field limit of the Vlasov–Poisson–Fokker–Planck system for charged particles is rigorously derived. The first result is obtained in any space dimension by using modulated energy techniques. It requires the smoothness of the solutions of the limit problem. Air Max Toronto
In dimension 2, it is possible to handle more general data by using methods developed for a diagonal defect measures theory. The convergence of the concentration of particles is obtained in the space of bounded measures. In both cases, the limit of the sequence of densities of distribution functions is shown to solve a nonlinear system of partial differential equations which is related to Ohm's law.
Critical thinking refers to the individuals’ ability to think and make correct decisions independently. Nowadays enhancing critical thinking in learners is considered one of the foreign language teachers’ tasks due to its high position in foreign language classrooms. There are various factors affecting language learners’ critical thinking skills. Among these factors is the assessment methods used. Therefore, through managing the ways of assessing language learners’ ability, language teachers can help them develop critical thinking skills. In this presentation, some suggestions for language teachers to make sound choice of assessment methods and Air Max 1 activities will be presented.
