Consequently, it would eventually be replaced by Composition C-4. The velocity of detonation is about 7600 m/s (25,000 feet per second). Composition C-3 consists of 77%–85% cyclonite ( RDX ) and 15%–23% gel made out of liquid nitro compounds (e.g. liquid DNT and small amount of NT ) and nitrocellulose or butyl phthalate and nitrocellulose.
C-4 is a member of the Composition C family of chemical explosives. Variants have different proportions and plasticisers and include compositions C-2, C-3, and C-4. [3] The original RDX-based material was developed by the British during World War II and redeveloped as Composition C when introduced to the U.S. military. It was replaced by ...
C4-FN (C4-fluoronitrile, C4FN) is a perfluorinated compound developed as a high-dielectric gas for high-voltage switchgear. [1] It has the structure (CF 3 ) 2 CFC≡N, which can be described as perfluoro isobutyronitrile , falling under the category of PFAS , or per- and polyfluoroalkyl substances.
The C4 model was created by the software architect Simon Brown between 2006 and 2011 on the roots of Unified Modelling Language (UML) and the 4+1 architectural view model. The launch of an official website under a Creative Commons license [3] and an article [4] published in 2018 popularised the emerging technique. [1]
Americans are weathering the worst flu season in years, as a number of other respiratory illnesses circulate too, such as COVID-19, RSV and the common cold.
Sometimes the name "Réti Opening" is used for the opening move 1.Nf3, [1] although most sources define the Réti more narrowly as the sequence 1.Nf3 d5 2.c4. [2] A flank opening, it is the third most popular of the twenty legal opening moves White has, behind only 1.e4 and 1.d4. [3] [4] [5]
