The usual ordering “≤" on R is a total ordering, that is, for any two real numbers in R, we can determine their order without difficulty. However, for any two closed intervals in R, there is not a natural ordering among the set of all closed intervals in R. Several methods have been developed to compare two intervals. In this paper, we define the μ-ordering which is a new method for ordering cl...
We prove that affine configurations of 4 lines in R3 are topologically and combinatorially homeomorphic to affine configurations of 6 points in R4.
Quadratic theory of gravity is a complicated constraint system. We investigate some consequences of treating quadratic terms perturbatively (higher derivative version of backre-action effects), which is consistent with the way existence of quadratic terms was originally established (radiative loop effects and renormalization procedures which induced quadratic terms). We show that this approach ...
Let R be a commutative Noetherian ring, I an ideal of R and M a non-zero R-module. In this paper we calculate the extension of annihilator of local cohomology modules H^t_I(M), t≥0, under the ring extension R⊂R[X] (resp. R⊂R[[X]]). By using this extension we will present some of the faithfulness conditions of local cohomology modules, and show that if the Lynch's conjecture, i...
Background and Objective: There are evidences for the beneficial effects of probiotic products on non-alcoholic fatty liver disease (NAFLD). The aim of the current study was to investigate the effects of probiotic yogurt consumption compared to conventional yogurt on enzymes and ecogenisity of liver in patients with NAFLD. Materials and Methods: This study was conducted on 72 patients with NAFL...
در این پایان نامه ضمن معرفی مفاهیم اولیه در سیستم های دینامیکی، ارتباط بین نقاط تناوبی و نقاط ناسرگردان و همچنین نقاط بازگشتی و نقاط تناوبی را برای نگاشت های بازه ای به دست می آوریم و نشان می دهیم که در حالت کلی برای نگاشت های گرافی این رابطه برقرار نیست و رابطه ی اصلی را برای نگاشت های گرافی ارائه می دهیم. سرانجام در مورد وجود نقاط بازگشتی برای نگاشت های گرافی در کمان های مفروض، بحث می شود.
