The Keesler ground station is maintained as a backup to the primary system at NHC, which has greater data streaming capability, and would be manned by CARCAH personnel in the event of a long-term satellite communications failure at NHC. During temporary outages, 53rd personnel at Keesler act as operators and relay data from the aircraft by land ...
Ag I NHC complexes can be prepared by the methods described above, using Ag I sources. [6] The first to be reported was a [Ag I (NHC) 2] + synthesized through method 1 by Arduengo et al. in 1993. [4] The vast majority of these complexes are synthesized through method 2, due to the ease of using Ag 2 O with air stable imidazolium salts. [6]

As the name suggests, a non-nucleophilic base is a sterically hindered organic base that is a poor nucleophile.Normal bases are also nucleophiles, but often chemists seek the proton-removing ability of a base without any other functions.
Many military analysts consider the Wehrmacht, Nazi Germany's armed forces, as the pioneers of "jointness" (German: integrierter Kriegführung), pointing out that blitzkrieg, the war-fighting style that brought the Wehrmacht stunning victories between 1939 and 1941, depended upon the close integration of ground and air (and sometimes naval) forces and that even after the blitzkrieg campaigns ...
The .50 GI (12.7×23mmRB) pistol cartridge was developed by Alex Zimmermann of Guncrafter Industries.The .50 GI was introduced at the 2004 SHOT Show alongside the Guncrafter Industries Model No. 1, a variation of the M1911.
The system continued strengthening, with NOAA and Air Force Reserve Hurricane Hunters finding that Helene's maximum winds had increased to 80 mph (130 km/h). As a result, NHC upgraded the system to a hurricane by 15:00 UTC on September 25, as it entered the Gulf of Mexico while turning north.
The traditional 5-membered CAACs show similar nucleophilicity to the eight-membered NHC with calculated highest occupied molecular orbitals (HOMO) of 5.290 eV (CAAC-5) vs. 5.110 eV (NHC-8), decreasing the motivation to synthesize expanded ring CAACs. [14] As a result, ring-expanded CAACs have not been widely explored.
