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.
Hemivertebrae are a congenital deformity whereby parts of the vertebrae do not develop correctly, resulting in wedge shapes. As these wedged vertebrae line up, the spine may form one of three conditions: lordosis, a curvature in the lower back; kyphosis, a posterior curvature; or scoliosis, a lateral curvature. In many breeds, such as pugs, hemivertebrae development is encouraged, as it is responsible for the screw tail.
