two groups of students were assigned as experimental and control ones, and were given instruction on directed reading-thinking activities and after some treatment, they were post-tested. although the initial pre-test did not show any significant differences, the final post-test result revealed that the cooperative reading comprehension helped the experimental group. the cooperative students’...
bronchial asthma is the common chronic inflammatory disease and is characterized by chronic airway inflammation, airway remodeling, and airway hyperreactivity (ahr). aim of this study was to investigate the effects of mitochondrial atp-sensitive potassium channels (mitokatp) on the proliferation and secretion of human airway smooth muscle cells (hasmcs). hasmcs were treated with the serum from ...

the aim of this study was to determine the interactional effects of various video shows (skilled and self-model) and feedback type on performance and learning of dart throwing skill. 90 volunteers were randomly divided into 6 groups including self-control, experimenter control and yoked feedback that received either skilled model or self-model. three groups who watched the skilled model observe...
The control performance of the finite set model predictive current (FCS-MPCC) for interior permanent magnet synchronous machine (IPMSM) depends on accuracy mathematical model. A novel robust method based error compensation is proposed in order to reduce parameter sensitivity and improve robustness. In this method, equivalent parameters are obtained from known voltage information at past time be...
in this paper, stabilization conditions and controller design for a class of nonlinear systems are proposed. the proposed method is based on the nonlinear feedback, quadratic lyapunov function and heuristic slack matrices definition. these slack matrices in null products are derived using the properties of the system dynamics. based on the lyapunov stability theorem and sum of squares (sos) dec...
