Weinstein spectrum

The relative importance of structures 130 and 131 have long been discussed for the dye indanthrone. Initially, the infrared spectrum was considered to favor 131 ° because a vN—H band could not be found. However, this interpretation has been questioned, and recently the predominance of structure 130 was established by Weinstein and MerritP on the basis of the following evidence (a) a... 

Kaplunovsky and Weinstein [kaplu85j develop a field-theoretic formalism that treats the topology and dimension of the spacetime continuum as dynamically generated variables. Dimensionality is introduced out of the characteristic behavior of the energy spectrum of a system of a large number of coupled oscillators. 

In the experiments of Weinstein and Firestone [26], it was shown that the spectrum of the electron in mixed solvents depends on the mixture of the two components, for example, an alcohol and an ether. If complete relaxation were possible, one would expect that the solvent molecules would interchange and the result would be the lowest energy configuration. This does not appear to occur. 

For instance, if the solids flow rate is specified at Gs = 50 kg/(m2s), choking will take place at Ug = 3.21 m/s for system FCC/air as indicated in the figure. Throughout the entire regime spectrum, only at this unique point (l/pl, K ) can both dense-phase fluidization and dilute-phase transport coexist. At velocities higher than Upt, only dilute transport can exist, shown as Mode FD in Fig. 4 at velocities lower than l/pt, only dense-phase fluidization can take place, shown as Mode PFC in Fig. 4. The transition point at l/pt identifies the unique Mode PFC/FD on the curve of Fig. 5 for the coexistence of both modes, the relative proportion of which depends on other external conditions such as the imposed pressure APimp as reported by Weinstein et al. (1983).
