If you take blood-thinning medicines regularly, talk with your doctor about how to manage your medicine. Do not take sucralfate (Carafate) or antacids on the day of the test. These medicines can make it hard for your doctor to see your upper GI tract.Before the test, you will put on a hospital gown.If you are wearing dentures, jewelry, contact lenses, or glasses, remove them.For your own comfort, empty your bladder before the test.f you take blood-thinning medicines regularly, talk with your doctor about how to manage your medicine.

A cylinder has 2 flat surfaces and 1 curved surface. In differential geometry, a cylinder is defined more broadly as any ruled surface spanned by a one-parameter family of parallel lines.As such it can have any number of flat surfaces but need not have any at all.A cylinder whose cross section is an ellipse, parabola, or hyperbola is called an elliptic cylinder, parabolic cylinder, or hyperbolic cylinder respectively; these have no flat surfaces.s such it can have any number of flat surfaces but need not have any at all.

The hydraulic cylinder consists of a cylinder barrel, in which a piston connected to a piston rod moves back and forth. The barrel is closed on each end by the cylinder bottom (also called the cap end) and by the cylinder head where the piston rod comes out of the cylinder. The piston has sliding rings and seals.The piston divides the inside of the cylinder in two chambers, the bottom chamber (cap end) and the piston rod side chamber (rod end). The hydraulic pressure acts on the piston to do linear work and motion. Flanges, trunnions, and/or clevisses are mounted to the cylinder body.The piston rod also has mounting attachments to connect the hydraulic cylinder to the object or machine component that it is pushing.he hydraulic pressure acts on the piston to do linear work and motion.
