Muscle knots, also referred to as myofascial trigger points, are described as abnormal areas in the muscle, according to Seth Rosenbaum, M.D. Muscle knots often form when the muscle is experiencing a spasm. A muscle spasm occurs when a muscle is in a continuous contraction and typically follows an injury.t is characterized by having ongoing painful trigger points, or muscle knots, according to the MayoClinic.com. This pain tends to worsen or persist. Trigger point injections, physical therapy and medications can help to alleviate the pain and muscle knots.
Ethanol is produced from biomass mostly via a fermentation process using glucose derived from sugars (sugar cane, sugar beet and molasses), starch (corn, wheat, grains) or cellulose (forest products) as raw materials. In this form, it is renewable.
The most common crop used in the United States for making ethanol for gasoline additive is corn, whereas in tropical countries such as Brazil, the crop of choice is sugar cane. The amount of ethanol produced per unit mass of biomass, given in units of liters per kg (L/kg), varies from about 0.07 for sugar cane, 0.16 for wood, and 0.36 for corn.
