background: problem-based learning is a student-centered teaching method that encourages students to become active learners in the classroom and  to improve the learning processes.  the aim of this study was to compare two methods of teaching, problem- based learning (pbl) and lecture-based learning, in an embryology course. methods: this was a semi-experimental study conducted in kurdistan uni...

background: mullerian disorders are present in 5-25% of infertile women. myoma, polyp and endometrial adhesions are among other involved factors in infertility. objective: the aim of this study was to determine the frequency distribution of pregnancy occurrence in infertile women after the diagnostic-surgical hysteroscopy on selected infertile cases including those with abnormal uterine. materi...

purpose:     methods:     results:     conclusion:     our study suggests that using mpcd method is an effective way to increase clinical reasoning skills of medical students. the attitude of students about the positive effects of mpcd increased significantly from the first day to the last day (p intervention. 120 third-year medical students at our medical university were randomly assigned to 1...

Transportation problem is a linear programming which considers minimum cost for shipping a product from some origins to other destinations such as from factories to warehouse, or from a warehouse to supermarkets. To solve this problem simplex algorithmis utilized. In real projects costs and the value of supply and demands are fuzzy numbers and it is expected that optimal solutions for determini...

in this paper we consider a nonlinear two-phase stefan problem in one-dimensional space. the problem is mapped into a nonlinear volterra integral equation for the free boundary.

‎in this paper‎, ‎we find matrix representation of a class of sixth order sturm-liouville problem (slp) with separated‎, ‎self-adjoint boundary conditions and we show that such slp have finite spectrum‎. ‎also for a given matrix eigenvalue problem $hx=lambda vx$‎, ‎where $h$ is a block tridiagonal matrix and $v$ is a block diagonal matrix‎, ‎we find a sixth order boundary value problem of atkin...
