in Russian mathematical texts, normal, non-raised, ellipses are used even in repeated summations.The latter formula means the sum of all natural numbers from 1 to 100. However, it is not a formally defined mathematical symbol.
The knot in the noose is placed to the left of the condemned, so that at the end of the drop, the head is jolted sharply upwards and to the right. The force breaks the neck, causing an immediate loss of consciousness and death within a few minutes. Diagnosis
Physical examination
A medical history and physical examination can be sufficient in clearing the cervical spine. Notable clinical prediction rules to determine which patients need medical imaging are Canadian C-spine rule and the National Emergency X-Radiography Utilization Study (NEXUS). Choice of medical imaging
In children, a CT scan of the neck is indicated in more severe cases such as neurologic deficits, whereas X-ray is preferable in milder cases, by both US and UK guidelines. Swedish guidelines recommend CT rather than X-ray in all children over the age of 5. In adults, UK guidelines are largely similar as in children. US guidelines, on the other hand, recommend CT in all cases where medical imaging is indicated, and that X-ray is only acceptable where CT is not readily available. Radiographic detection
On CT scan or X-ray, a cervical fracture may be directly visualized.
