Thyroid eye disease (thyroid orbitopathy or TO) is a condition that causes the muscles and soft tissues of the eye socket to swell. It happens when you have a problem with your thyroid gland.he tears form a protective layer at the front of your eye and also help to direct the light coming into your eye. Your iris, the coloured circle at the front of your eye, changes the size of the pupil which is the dark hole in the middle of the coloured part of your eye.
What is the redline of an engine? All engines have a redline, which is the maximum rpm value they can accommodate. Beyond the redline, the engine will explode. Since you would probably prefer that your engine not explode, you have to keep an eye on the redline, especially in a manual-transmission car. When you shift gears in a manual transmission car, you're making sure that the engine stays below the redline. To shift gears, you move the gear shift and hold down the clutch. The shift lever controls rods that control forks that engage the gears. The clutch is what connects the engine to the transmission.
Essentially, a radial engine works through a process of reciprocating combustion. There are several cylinders that all radiate out from the crankcase. This design gives it an appearance that led to it being called the âstar engineâ in some languages such as German and French.
