A method for obtaining phases of low-order reflections is presented. It is based on four observations: (1) the electron density inside proteins is smooth and uniform at low resolution. (2) Since all proteins have almost the same density, the total volume of the protein is known if the molecular weight is known. (3) The overall shape of many proteins is fairly spherical. (4) The total scattering...

Background: Nowadays, the optimization of the culture conditions in bioreactors is considered as an approach to produce secondary metabolites such as thebaine. Thebaine is the dominant alkaloid in Iranian poppy that is used as a precursor for the synthesis of analgesic compounds. Objective: Optimization of culture conditions of Papaver bracteatum adventitious roots in bioreactor for the scale...
