SpletThe original Mass Effect series is designed as a trilogy, which allows the player to import their characters from any completed Mass Effect playthrough to subsequent games. This means that several decisions Commander Shepard makes in Mass Effect will carry over and have the potential to impact the story of Mass Effect 2, which in turn affects Mass Effect …
SpletTemperature affects gas–liquid mass transfer through its effect on H2 diffusion, solubility, and biological activity, and it is therefore an important parameter in biological methanation. Increasing temperature will decrease the aqueous solubility of H 2, but will also increase H 2 diffusivity and thus the mass transfer coefficient [ Eq.
