New radiocarbon dates from the University of Washington's Quaternary Isotope Laboratory are given for Cornwallis Island, Northwest Territories, Canada, and these and other radiocarbon dates for the area are assembled in a diagram, including the envelope of a tentative emergence curve. Most of the new dates are derived from surface collections but appear to represent a consistent altitude–age relationship confirming the pattern of previously published dates for the general region.The oldest of the new Holocene dates on marine shells indicate that the Resolute Bay area began emerging by at least 9700 years BP. The highest well developed marine strandlines recognized to date are at an altitude of ca. 105 m. However, the postglacial marine limit is probably some 10 m or more higher. As in adjacent regions, early postglacial emergence was initially rapid, of the order of an average 8.3 m/100 years for the first recorded 75 m, then slowed to an average 0.5 m/100 years for the last 40 m.

A rocket-borne cooled (S-1) filter photometer was flown from Resolute Bay, Northwest Territories 75° N during geomagnetically quiet conditions. The derived altitude profile of the (6–2) hydroxyl band emission shows a peak at 95 km. An airglow background of 2.7 R A−1 or less at 8380 A is reported for altitudes above 125 km.

The main provisions of the concept of technology of diamond cutting and drilling of building structures are considered. The innovativeness of the technology, its main possibilities and advantages are presented. Carrying out works with the help of this technology in underwater conditions expands its use when constructing and reconstructing hydraulic structure. The use of diamond drilling equipment with motors equipped with an internal combustion engine is considered. Drilling holes with a variable diameter during the reconstruction of the runways of airfields makes it possible to combine the landing mats into a single structure. The ability to cut inside the concrete mass, parallel to the front surface, has no analogues among the methods of concrete treatment. The use of this technology for producing blind openings in the body of concrete without weakening the structure is also unique. Work with precision quality in cutting and diamond drilling of concrete and reinforced concrete was noted by architects and began to be implemented in the manufacture of inter-room and inter-floor openings. Non-destructive approach to the fragmentation of building structures allows them to be reused. The technology of diamond cutting and drilling is located at the junction of new construction, repair, reconstruction of buildings and structures, and dismantling of structures. Attention is paid to the complexity and combinatorial application of diamond technology. Economic efficiency and ecological safety of diamond technology are presented. The main directions of further research for the development of technology are indicated.
