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.
Green bananas contain up to 70-80% starch, on a dry weight basis. During ripening, the starch is converted into sugars and ends up being less than 1% when the banana is fully ripe (2). The most common types of sugar found in ripe bananas are sucrose, fructose and glucose. In ripe bananas, the total content of sugars can reach more than 16% of the fresh weight (2).
