A metal-composite corrugated hose having a wall including a metal layer forming its innermost layer and a resin layer surrounding it. The method includes forming a first field effect transistor device and a second FET device on a semiconductor substrate. The second code, when executed by the second computing device, causes the second computing device to automatically retrieve the second network resource identified by the second universal resource locator, and automatically invoke execution of second content player code that configures the second computing device to present the content information. A buffer gate electrode layer is formed on top of the metal gate electrode layer and a top gate electrode layer having a poly-silicon alloy is formed over the metal gate electrode layer. Also provided are methods for utilizing ribG polypeptides to screen for antibacterial compounds. In an embodiment, a method includes providing each individual of a group with a wireless audio playback unit, and transmitting body movement instruction signals to the audio playback units of each individual of the group.
