Like [1.1.1]propellane, 1,3-dehydroadamantane can be polymerized by breaking the axial bond and joining the resulting radicals into a linear chain: Scheme 2: Polymerization of 1,3-dehydroadamantane. In this scheme, 1,3-dehydroadamantane is reacted with acrylonitrile in a radical polymerization initiated with lithium metal in tetrahydrofuran.
[1] [2] The PMI guide Requirements Management: A Practical Guide recommends that a requirements tool should be identified at the beginning of the project, as [requirements] traceability can get complex and that switching tool mid-term could present a challenge. [3] According to ISO/IEC TR 24766:2009, [4] six major tool capabilities exist:
The nuclear magnetic resonance (NMR) spectrum of adamantane consists of two poorly resolved signals, which correspond to sites 1 and 2 (see picture below). The 1 H and 13 C NMR chemical shifts are respectively 1.873 and 1.756 ppm and are 28.46 and 37.85 ppm. [28] The simplicity of these spectra is consistent with high molecular symmetry.
[1] [2] Its target systems are the PlayStation 3, the Xbox 360, Microsoft Windows and the Wii. [1] On the development side, the engine takes the form of various authoring tools focused on large-scale game projects. [1] [3] It encompasses a character viewer for 3D models, an effects and a cutscene editor, a previsualization tool, and a sound maker.

Bladesmith, Nuremberg, Germany, 1569 Bladesmithing is the art of making knives, swords, daggers and other blades using a forge, hammer, anvil, and other smithing tools. [1] [2] [3] Bladesmiths employ a variety of metalworking techniques similar to those used by blacksmiths, as well as woodworking for knife and sword handles, and often leatherworking for sheaths. [4]
Adamant and the literary form adamantine occur in works such as The Faerie Queene, Paradise Lost, Gulliver's Travels, The Adventures of Tom Sawyer, The Lord of the Rings, [4] and the film Forbidden Planet (as "adamantine steel"). All these uses predate the use of adamantium in Marvel's comics. [4]
