During the initial discovery period of global climate change, the magnitude of the influence of the Sun on Earth's climate was not well understood. Since the early 1990s, however, extensive research was put into determining what role, if any, the Sun has in global warming or climate change.
Paracentral Herniating Disc. A paracentral herniation occurs when the bulge of the affected intervertebral disc points in direction of the middle part of the spinal canal, also called the foramen. The word âparacentralâ originates from the Greek and means ânear the centerâ of something.
A bulging disk is different from a herniated disk in that a bulging disk typically occurs gradually over time rather than suddenly. A herniated disk is often the result of an injury or trauma to the spine. In the majority of patients who experience a bulging disk, there is no pain unless the disk becomes herniated or protrudes into a nerve. In many cases, a bulging disk may be diagnosed as a condition secondary to another problem.
