By averaging all 6 values, we can estimate that an average European Swallow flies at cruising speed with a frequency of roughly 15 beats per. second, and an amplitude of roughly 22 cm. Last monthâs article on The Strouhal Number in Cruising Flight showed how simplified flight waveforms that graph amplitude versus.
In the anteroposterior direction, the curvature is referred to as kyphosis (increased posterior convexity of the spine) or lordosis (increased posterior concavity of the spine). Most scoliosis also has a rotational component. Conventional radiographs (x-rays) are an excellent means for assessing scoliosis.ospital for Special Surgery. Spinal malalignment-Scoliosis and Listhesis. Scoliosis refers to abnormal curvature of the spine. Scoliosis may result from various structural causes, although the most common form of scoliosis is called idiopathic scoliosis, which has no known cause.
