Large Area Listening Systems. Large area listening systems are the most popular of all hearing enhancement devices, and are used in theaters, movie houses, auditoriums and houses of worship. There are three basic types: FM radio, infra-red (IR) light and a looped wire around the room, called an induction loop.
The strings are called Phloem Bundles (pronounced flom). They are part of the system that carries nutrition to all parts of the banana.
A banana packs nearly 3 grams of fiber into your diet if you eat a 6-inch piece of the fruit. Most of the fiber in bananas is insoluble. This is the type of fiber that pushes out waste and makes your stools easier for you to pass. Bananas also have a small amount of soluble fiber. As soluble fiber travels through your intestines, it soaks up liquid and creates a thick sludge.
