[ 1 ] - The Role of Thermal Conduction in Accretion Disks with Outflows
In this work we solve the set of hydrodynamical equations for accretion disks in the spherical coordinates (r,θ,ϕ) to obtain the explicit structure along θ direction. We study a two-dimensional advective accretion disc in the presence of thermal conduction. We find self-similar solutions for an axisymmetric, rotating, steady, viscous-resistive disk. We show that the global structure of an advec...
[ 2 ] - Comparing postpartum stressors and social support level in primiparous and multiparous women
Background and aim: Postpartum period is an exclusive period after birth which can act as a potential stressor and could be accompanied with psychological disorders. Social support could play an important role in maternal mental health. Considering various stressors and different levels of social support for women, this study aimed to compare postpartum stressors as well as social support level...
[ 3 ] - تحول دینامیکی قرصهای برافزایشی خودگرانشی پلی تروپ با وشکسانی بتا در حضور میدان مغناطیسی چنبرهای
In this paper,the effect of troidal magnetic field is studied in standard self-gravitating thin disks with β priscription. By applying the magnetic field, we expect to see different behaviors compared to a non-magnetic field case.The study reveals self-similar solutions for radial infall velocity, rotation velocity, surface density and mass accretion rate. Our results also show that by increasi...
