The third segment is situated in the open ocean, and consists of a perpendicular to the closing line of the Gulf from the point at which the corrected median line intersects with that line. The delimitation line corresponds to the corrected median line from its intersection with the above-mentioned bisector to the point where it reaches the closing line of the Gulf. For the second segment, the Chamber considered that, in view of the quasi-parallelism between the coasts of Nova Scotia and Massachusetts, a median line should be drawn approximately parallel to the two opposite coasts, and should then be corrected to take account of (a) the difference in length between the coasts of the two States abutting on the delimitation area and (b) the presence of Seal Island off the coast of Nova Scotia. The delimitation line runs from the starting-point agreed between the Parties, and is the bisector of the angle formed by the perpendicular to the coastal line running from Cape Elizabeth to the existing boundary terminus and the perpendicular to the coastal line running from that boundary terminus to Cape Sable. In the case of the first segment, it considered that there was no special circumstance precluding the division into equal parts of the overlapping of the maritime projections of the two States’ coasts. As for the plotting of the delimitation line, the Chamber distinguished between three segments, the first two lying within the Gulf of Maine and the third outside it. It applied criteria of a primarily geographical nature, and used geometrical methods appropriate both for the delimitation of the sea-bed and for that of the superjacent waters. It rejected the delimitation lines proposed by the Parties, and defined the criteria and methods which it considered to be applicable to the single delimitation line which it was asked to draw. It indicated that the delimitation was to be effected by the application of equitable criteria and by the use of practical methods capable of ensuring, with regard to the geographical configuration of the area and the other relevant circumstances, an equitable result. Having established its jurisdiction and defined the area to be delimited, it reviewed the origin and development of the dispute and laid down the principles and rules of international law governing the issue. The Chamber delivered its Judgment on 12 October 1984. This Chamber was constituted by an Order of 20 January 1982, and it was the first time that a case had been heard by an ad hoc Chamber of the Court. Copyright © 2021 by Mutaz B.On 25 November 1981, Canada and the United States notified to the Court a Special Agreement whereby they referred to a Chamber of the Court the question of the delimitation of the maritime boundary dividing the continental shelf and fisheries zones of the two Parties in the Gulf of Maine area. ![]() This new simple method proposed for demarcation of the nasopharyngeal anterior boundary was based on the innate anatomical boundary, which was statistically reliable, technically convenient, and clinically reasonable. Paired t test showed no significant difference between the first and the second examinations. Both the interobserver reliability as well as the intra-observer reliability were very high (intraclass correlation coefficients, 0.985–0.997). The area of the anterior and the inferior boundaries, and the volume of the nasopharynx were measured and repeated with a 2-week interval for the consistency test. ![]() ![]() Precise localization of the reference points that determining the nasopharyngeal anterior and inferior boundaries was managed by recording their coordinates in the interface of the software. Twenty computed tomography scans (age 9.5 ± 2.5 years, 11 males, and 9 females) of head and neck were randomly selected and transferred to Materialism's interactive medical image control system 19.0 for segmentation of the nasopharynx. The present study was to propose a new method based on the anatomical definition for the anterior boundary demarcation of the nasopharynx used in three-dimensional analysis. ![]() Three-dimensional (3D) measurements of the upper airway have been extensively applied and researched, but the division of the airway is carried out in various ways, especially when demarcating the anterior boundary of the nasopharynx.
