It is also occasioned by anodic polarization of iron in sulphuric acid.
His declared sympathy with Brutus and Cassius occasioned his banishment in 66.
Another form of isomerism is occasioned by spatial arrangements, many of the reduced terephthalic acids existing in two stereo-isomeric forms. Baeyer explains this by analogy with fumaric and maleic acids: he assumes the reduced benzene ring to lie in a plane; when both carboxyl groups are on the same side of this plane, the acids, in general, resemble maleic acids, these forms he denotes by rcis-cis, or shortly cis-; when the carboxyl groups are on opposite sides, the acids correspond to fumaric acid, these forms are denoted by rcis-trans, or shortly trans-.
The alchemists used the terms fermentation, digestion and putrefaction indiscriminately; any reaction in which chemical energy was displayed in some form or other - such, for instance, as the effervescence occasioned by the addition of an acid to an alkaline solution - was described as a fermentation (Lat.
It was the great work of Descartes to exclude rigorously from science all explanations which were not scientifically verifiable; and the prevalence of materialism at certain epochs, as in the enlightenment of the 18th century and in the German philosophy of the middle, 9th, were occasioned by special need to vindicate the scientific position, in the former case against the Church, in the latter case against the pseudo-science of the Hegelian dialectic. The chief definite periods of materialism are the pre-Socratic and the post-Aristotelian in Greece, the 18th century in France, and in Germany the, 9th century from about 1850 to 1880.

Repudiation of the tie by fervent women, betrothed or already wives, occasioned much domestic friction and popular persecution.
Meteorological optical phenomena, due to variations in the refractive index of the atmosphere, may be divided into groups: (I) those due to the permanent or normal variation experienced as one ascends in the atmosphere, and (2) those due to sporadic variations occasioned by irregular heating.
Forced back by Seti, the Kheta returned and were found holding Kadesh by Rameses II., who, in his fifth year, there fought against them and a large body of allies, drawn probably in part from beyond Taurus, the battle which occasioned the monumental poem of Pentaur.
He taught with great regularity for upward of thirty years, the only interruptions being that of 1813-1814 (occasioned by the War of Liberation, during which the university was closed) and those occasioned by two prolonged literary tours, first in 1820 to Paris, London and Oxford with his colleague Johann Karl Thilo (1794-1853) for the examination of rare oriental manuscripts, and in 1835 to England and Holland in connexion with his Phoenician studies.
