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.
In cellular biology, an electrochemical gradient refers to the electrical and chemical properties across a membrane. These are often due to ion gradients, particularly proton gradients, and can represent a type of potential energy available for work in a cell.n electrochemical gradient has two components. First, the electrical component is caused by a charge difference across the lipid membrane. Second, a chemical component is caused by a differential concentration of ions across the membrane.
