Data were analyzed by descriptive-statistical methods.Findings: Data obtained from the age groups of under and over 40 years old as w...
هدف: کشت سلول های اسپرماتوگونی و تولید سلول های پر توان embryonic stem cells (es like cells) که دارای قابلیت بازسازی و تولید هرسه نوع لایه زایای جنینی می باشند، این سلول ها را به عنوان منبع کافی و جدیدی برای سلول درمانی و ترمیم در بیماریها از جمله بیماریهای نورودژنراتیو پیشنهاد می دهد. در تحقیق حاضر تمایز سلول های اسپرماتوگونی موش به سلول های شبه الیگودندروسیت و نقش آنها درمیلین سازی پس از پیون...
In this paper, we survey some of latest developments in using preconditioned conjugate gradient methods for solving mildly ill-conditioned Toeplitz systems where the condition numbers of the systems grow like O(n) for some > 0. This corresponds to Toeplitz matrices generated by functions having zeros of order. Because of the ill-conditioning, the number of iterations required for convergence in...
In this paper, we would like to briefly introduce some applications of fractional derivatives in the fields heat and fluid-flows. However, our main focus is on study an inverse source problem for Rayleigh-Stokes problem. The severely ill-posed. We verify ill-posedness Problem 1, applying modified Lavrentiev construct a regularization from exact data. After that, established convergent rate betw...
