prominence

 [prom´ĭ-nens]
a protrusion or projection.
frontonasal prominence an expansive facial process in the embryo that develops into the forehead and bridge of the nose; called also frontonasal process.
laryngeal prominence a subcutaneous prominence at the front of the throat produced by the thyroid cartilage of the larynx; popularly known as Adam's apple.
mandibular prominence the ventral prominence formed by bifurcation of the first branchial arch (mandibular arch) in the embryo, which unites ventrally with its fellow to form the lower jaw; called also mandibular process.
maxillary prominence the dorsal process formed by bifurcation of the first branchial arch (mandibular arch) in the embryo, which joins with the ipsilateral median nasal process in the formation of the upper jaw. Called also maxillary process.

Here we performed a cadaveric experiment and related survey study to compare the relative efficacies of the lateral and dorsal tangential (DT) views in the identification of dorsal screw prominence across training backgrounds.
However, the assumption of a homogeneous magnetic field provides us a relatively simple mathematical model to study MHD waves in solar prominence. Several authors [6, 15, 16] used homogeneous magnetic field to study MHD waves in different regions of solar atmosphere.
A notable arch prominence was on the NE limb on Sep 4 but was not present on Sep 5.
Rotating discs in solar prominences were first observed decades ago, using ground-based telescopes, and have puzzled solar physicists since.
In a 1996 study of some 50 such filaments seen in satellite observations, researchers led by Rust concluded that the S shapes were top-down views of extraordinarily hot, twisted prominences. Some scientists suspect that if prominences get too twisted, they become unstable and erupt.
The solar prominence - a magnetically charged cloud of heated gas, known as plasma - erupted above the surface of the sun and was observed by the SDO on Feb.
Near the coronal base, the increased magnetic heating counterbalances the extra cooling, but less heating occurs near the top, allowing enough gas to cool and condense into prominences.
On April 3 a flame prominence was notable on the NW limb and also a rough square shaped prominence hearth on the NE limb.

Until that day, none of the several hundred extended prominences photographed over nine years by Solar Max's coronagraph/polarimeter had been seen returning, says the instrument's chief experimenter, Arthur J.
A hedgerow prominence hearth was seen extending around the SW limb on Feb 7 for about 251,000km and rising to a height of 102,000km.
