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.
Hereâs Thierry with more info: Bananas contain a protein called lectin, which is also found in many of the ânight shadeâ foods that some people with Celiac or gluten intolerance have trouble with. Lectin is somewhat similar to gluten and can create an autoimmune response. This is due to the body confusing lectin with gluten.
