simulation of the transfer process in the blast furnace shaft with layered burden
Applied Thermal Engineering, 2016Co-Authors: Ping Zhou, Pengyu Shi, Chenn Q ZhouAbstract:Abstract A symmetric, two dimensional, steady state burden distribution model is proposed to simulate the flow of gases and solids in a blast furnace. The Charged Material is treated as porous media with alternating coke and ore layers of different permeability. Their heat transfer processes coupled with fluid flowing and chemical reactions are predicted by Fluent . To investigate the influence of the layered burden treatment on the calculated in-furnace condition, a mixed burden model, in which the charging Materials are assumed as mixed layer of coke and ore, has also been developed with the same boundary condition except for the burden properties. The results indicate that the layered burden treatment has great influence on the calculated temperature distribution as well as the gas pressure distribution. Validation of the layered burden treatment has also been performed. The gas temperature at the furnace top as well as the gas pressure at the furnace wall are in good agreement with the measured data in the operating blast furnace. Obviously, a mathematical model that takes the layered structure into consideration is necessary to simulate the temperature and chemical reactions of Materials in the blast furnace.

Impact of emotion on memory: Controlled study of the influence of emotionally Charged Material on declarative memory in Alzheimer's disease
British Journal of Psychiatry, 2000Co-Authors: Hideki Kazui, S. Tanimukai, E Mori, Tokiji Hanihara, M. Hashimoto, T Imamura, Nobutsugu Hirono, Laurence CahillAbstract:BACKGROUND: In an earlier study we showed that a powerful emotional experience (the Kobe earthquake) reinforced memory retention in patients with Alzheimer's disease, but we could not control factors other than the emotional impact of the earthquake. AIMS: To test our previous findings in a controlled experimental study. METHOD: Recall tests consisting of two short stories were administered to 34 patients with Alzheimer's disease and 10 normal subjects. The two stories were identical except for one passage in each story: one was emotionally Charged (arousing story) and the other (neutral story) was not. RESULTS: In both groups, the emotionally Charged passage in the arousing story was remembered better than the counterpart in the neutral story. In addition, the extent of the memory improvement was similar in the subjects and in the controls. CONCLUSIONS: The results provide further evidence that emotional arousal enhances declarative memory in patients with Alzheimer's disease, and give a clue to the management of people with dementia.
