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.
edge gradient in radiology, the penumbra or partial shadow on a radiograph caused by the three-dimensional shape of an object. electrochemical gradient the difference in ion concentration and electrical potential from one point to another, so that ions tend to move passively along it.ntestinal electrochemical gradient. electrical potential differences and ion concentration differences across the external membrane of the intestinal mucosa arising from the active transport of most electrolytes and some nonelectrolytes across the membrane.
