Maple sap, as it comes from the tree is a clear, slightly sweet liquid. The sugar content rages from one to four percent. A device called a hydrometer can be floated in the sap to determine the exact sugar content. Sweeter sap is favored because less water will have to be evaporated to make maple syrup.t takes about forty gallons of this slightly sweet sap, boiled down, to make one gallon of pure maple syrup. The sugarmaker concentrates his attention to the front of the evaporator where the boiling sap is turning a golden color as it approaches being maple syrup.
Overview: Otosclerosis is a common condition affecting the bone of the otic capsule in 7.3% of Caucasian males and 10.3% of Caucasian females. The condition is rare in non-Caucasians, except East Indians, in whom the incidence is approximately the same as persons of northern or central European origin.
If excessive bone growth interferes with the stapes ability to vibrate and transmit sound waves, hearing loss will result. Otosclerosis is classified as a conductive disorder because it involves the bones of the ear, which conduct the sound to the nerve.If a person has hearing loss classified as neural, the nerve conducting the impulses to the brain is involved.Otosclerosis is a common hereditary condition.eople with otosclerosis almost never become totally deaf, and will usually be able to hear with a hearing aid or with surgery plus a hearing aid. In older people, the tendency for additional hearing loss is diminished due to the hardening of the bones.
