Background: Setting up an in vitro follicle culture system that resembles in vivo ovary condition has high value in research. Additionally, expression evaluation of folliculogenesis involved genes could lead us to the designing of better culture system. Materials and Methods: ovaries of 12-day-old female NMRI mice were removed, 100-130 μm pre-antral follicles were mechanically isolated from fre...
in the current study, an effort is made to determine three dimensional bearing capacity of rectangular foundations using discrete element method. the soil mass is modeled as discrete blocks connected with winkler springs. different factors affect the geometry of failure surface. six independent angles are used to define the failure surface. by trial and error, the optimum shape of failure surfa...
