language textbooks are conventionally expected to develop the four language macro-skills, including listening, reading, writing and speaking in language learners. however, mastering the reading skill is of particular importance, since it enhances the comprehension of specialized texts in students. the objective of this research is to investigate the scientific aspect of persian textbooks in tea...

objective: the aim of the current study is to investigate the relationship between metacognition and obsessive beliefs, and procrastination. methods: 285 students of tabriz and mohaghegh ardabili universities, iran, were selected by random sampling, and completed the metacognition (mcq-30) questionnaire, obsessive beliefs questionnaire (obq-44), and general procrastination scale. the research m...

We report a numerical analysis of the Anderson transition in a quantum-chaotic system, the quasiperiodic kicked rotor with three incommensurate frequencies. It is shown that this dynamical system exhibits the same critical phenomena as the truly random 3D-Anderson model. By taking proper account of systematic corrections to one-parameter scaling, the universality of the critical exponent is dem...

We study numerically multifractal properties of two models of one-dimensional quantum maps: a map with pseudointegrable dynamics and intermediate spectral statistics and a map with an Anderson-like transition recently implemented with cold atoms. Using extensive numerical simulations, we compute the multifractal exponents of quantum wave functions and study their properties, with the help of tw...

The influence of irradiation with white light on the permeability at 77 K is investigated on p-type yttrium iron garnet single crystals with Pb impurity. Theexistence of an irreversible photo-magnetic effect and photo-accelerated disaccommodation is demonstrated in p-type YIG. These effects are explained by a modified two center model in which Fe4+ plays an important role.

The Anderson model for independent electrons in a disordered potential is transformed analytically and exactly to a basis of random extended states leading to a variant of augmented space. In addition to the widely accepted phase diagrams in all physical dimensions, a plethora of additional, weaker Anderson transitions are found, characterized by the long-distance behavior of states. Critical d...
