The breaking of the large hydrocarbon molecules into smaller molecules is more technically referred to by organic chemists as " scission " of the carbon-to-carbon bonds.
42.
Scission is easily achieved by ultraviolet irradiation in the presence of oxygen gas, which suggests that adhesive devices employing diffusive bonding actually benefit from prolonged exposure to heat / light and air.
43.
The first process of degradation in OXO-treated plastic is an oxidative chain scission that is catalyzed by metal salts leading to oxygenated ( hydroxylated and carboxylated ) shorter-chain molecules.
44.
For example, polyethylene usually degrades by " random scission " that is by a random breakage of the linkages ( bonds ) that hold the atoms of the polymer together.
45.
"' Olefin metathesis "'is an organic reaction that entails the redistribution of fragments of alkenes ( olefins ) by the scission and regeneration of carbon-carbon double bonds.
46.
In 2011, the BLOC created a coalition Coalici?Comprom�s, running alongside Iniciativa del Poble Valenci?( a scission of United Left ) and the Green, both partners in the previous coalition.

C'est en 1882 que Maria Deraismes fut initi�e dans la loge fran�aise " Les Libres Penseurs " de Pecq de la " Grande Loge Symbolique �cossaise " ( scission du Supr�me Conseil de France ).
48.
For example, beta-scission of a weak C-S bond was used to favor one of two equilibrating radicals in metal free conversion of phenols to aromatic esters and acids via C-O transposition.
49.
Following the left-wing scission in 1971, the Radical Party " valoisien " maintained the judicial rights to the official name of Republican, Radical and Radical-Socialist Party and is its legal continuation.
50.
The organization was founded in 1979 as " Escoltes de Mallorca ", after a scission of the Roman Catholic " Moviment Escolta i Guiatge a Mallorca " within the Movimiento Scout Cat�lico in 1975.
