WebIn this paper, I argue against Terry Pinkard's account of the relation between Deweyian pragmatism and Hegelian idealism. Instead of thinking that their affinity concerns the issue of normative authority, as Pinkard does, I argue that we should trace their affinity to Dewey's appropriation of Hegel's naturalism, especially his theory of habits. cisco 9300 how to stackWebThe McCumber relation [1] [2] expresses the emission cross-seccion in terms of the absorption cross-section : where is temperature, is Boltzmann constant and is zero-line … cisco 9300 show power supply statusWebWe present Emission and absorption cross sections of thulium doped calcium fluoride (Tm:CaF 2) in the visible to short wave infrared (SWIR) wavelength range for temperatures between 80 K and 300 K.For spectral regions of high and low absorption the McCumber relation and the Fuchtbauer-Ladenburg equation have been used to give reliable results. diamond point shadows paysonWebMcCumber theory, which is developed for the study of phonon-terminated lasers based upon transition metal ions [1], gives a more accurate expression for the reciprocity relation between absorption and emission cross sections than FL equation.
