The boiler generates high pressure steam by transfering the heat of Combustion in various heat transfer sections. This part of the article series briefly describes the flow and arrangement of the heat transfer sections in a boiler. In line diagrams help make the concept clear.
Abnormalities found within vertebral bones are called transitional vertebrae. The spinal cord runs through the middle of the human spine. Chiropractic manipulation may help treat problems caused by misaligned vertebrae. The tailbone, or coccyx, is the lowest segment of the spinal column.
Most compression fractures happen in the front of the vertebra. When you get enough of them, the front part of the bone can collapse. The back of the vertebra is made of harder bone, so it stays intact. That creates a wedge-shaped vertebra, which can lead to the stooped posture you might know as a dowager's hump. Doctors call it kyphosis.
