Historically, the division of Jews in many Western countries into denominations, which in the United States in particular took the form of three large groups known as Orthodox, Conservative and Reform, can be traced to Jewish reaction to the Haskalah ( Jewish Enlightenment ) and its aftermath, and to a certain extent the philosophies of these movements were shaped in reaction to one another.

The required amount of carbon tetrachloride was distilled into a series of reaction cells on a manifold on a vacuum line.

Following observation of the fact that the reaction rates of supposedly identical reaction mixtures prepared on the same filling manifold and exposed under identical conditions often differed by several hundred per cent, a systematic series of experiments was undertaken to see whether the difficulty could be ascribed to the method of preparing the chlorine, to the effects of oxygen or moisture or to the effect of surface to volume ratio in the reaction tubes.

The improvement was most noticeable in the greater consistency among reaction cells prepared as a group on the same manifold.

Some 80 reaction tubes from 13 manifold fillings were illuminated in the temperature range from 40 to 85-degrees in a further endeavor to determine the cause of the irreproducibility and to obtain information on the activation energy and the effect of light intensity.

By comparing reaction cells sealed from the same manifold temperature dependency corresponding to activation energies ranging from 11 to 18 Af was observed while dependence on the first power of the light intensity seemed to be indicated in most cases.

It was possible to make estimates of the quantum yield by observing the extent of reduction of a uranyl oxalate actinometer solution illuminated for a known time in a typical reaction cell and making appropriate conversions based on the differences in the absorption spectra of uranyl oxalate and of chlorine, and considering the spectral distribution of the light source.

-- Although there was some variation in results which must be attributed either to trace impurities or to variation in wall effects, the photochemical exchange in the gas phase was sufficiently reproducible so that it seemed meaningful to compare the reaction rates in different series of reaction tubes for the purpose of obtaining information on the effect of chlorine concentration and of carbon tetrachloride concentration on the reaction rate.

As the name suggests, the postmodernist movement formed partly in reaction to modernism.

As the name suggests, the postmodernist movement formed partly in reaction to the ideals of modernism, but in fact postmodern music is more to do with functionality and the effect of globalization than it is with a specific reaction, movement, or attitude ( Beard and Gloag 2005, 142 ).

Joseph Priestley, for example, in referring to the reaction of steam on iron, whilst fully acknowledging that the iron gains weight as it binds with oxygen to form a calx, iron oxide, iron also loses “ the basis of inflammable air ( hydrogen ), and this is the substance or principle, to which we give the name phlogiston .” Following Lavoisier ’ s description of oxygen as the oxidizing principle ( hence the name oxygen: oxus
