The Mill
the sky demands, and the ray upon the Mill insists upon."[21] The strikingly different appreciation of the painting may have to do with Turner's mindset, but the actual appearance of The Mill was also changing as the result of discolored or tinted varnish. In 1834 the painting was described by C. J. Nieuwenhuys in the following

A revised 10-item version of the Achievement Motives Scale
The Achievement Motives Scale (AMS) is a well-established and frequently used scale to assess hope of success and fear of failure. In three studies with German-speaking samples (N = 3523, N = 132, N = 126), the authors developed a revised form of the AMS using confirmatory factor analysis. As found in previous research, the original 30-item set of …
The Basics of Brick and Refractories for Ferrous Foundries
Gary Bases. In the production of pig iron, brick and refractory materials are used to form the very large ovens or retorts (coke ovens) in which coal is converted to coke. Refractory and brick materials are needed to line huge shaft-like blast furnaces in which the molten pig is formed. The auxiliary furnaces or hot blast stoves, which heat the ...

Refractory Period
Definition. The refractory period of a neuron is the time in which a nerve cell is unable to fire an action potential (nerve impulse). Two subsets exist in terms of neurons: absolute refractory period and relative refractory period. The first describes the inability to send a new impulse when sodium channels preceding this impulse are …
