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.
The exact cause of otosclerosis is unknown. It may be passed down through families. People who have otosclerosis have an abnormal sponge-like bone growing in the middle ear. This growth prevents the ear bones from vibrating in response to sound waves. These vibrations are needed in order for you to hear. Otosclerosis is the most common cause of middle ear hearing loss in young adults. It typically begins in early to mid-adulthood. It is more common in women than in men. The condition may affect one or both ears. Risks for this condition include pregnancy and a family history of hearing loss.
