In Section 3, we analyze the case ofindirect government control, i.e., state subsidization of privately owned media. We endoge-nize government control in Section 4, asking when the government would choose to take overprivately owned media. Section 5 extends the model to multiple media outlets.
Small Angle Gradient Echo Methods. The gradient echo technique is generally used in combination with an RF excitation pulse that has a small flip angle of less than 90Ë. We will discover that the advantage of this is that it permits the use of shorter TR values and this, in turn, produces faster image acquisition.
An electrochemical gradient is a gradient of electrochemical potential, usually for an ion that can move across a membrane.n biological processes, the direction an ion moves by diffusion or active transport across a membrane is determined by the electrochemical gradient. In mitochondria and chloroplasts, proton gradients are used to generate a chemiosmotic potential that is also known as a proton motive force.
