Electrical Energy Management in the Cement Industry
A cement plant uses about 150 kWh of electrical energy per metric ton of cement produced. Where is this electrical energy being used? How is it being used? Can it be utilized more effectively? If so, how? What can be done to conserve the electrical energy used in an existing cement plant and in future cement plants? An electrical energy management program to resolve these questions is presented. Included is an electrical energy consumption survey of five cement plants. Department consumption is tabulated, and suggestions are made to conserve electrical energy and reduce cost of electrical power in both new and existing plants.
Optimizing Energy Utilization in Cement Plant Operations
With the increased cost of energy, use of energy in cement plants must be reduced. Various means of reducing energy use in existing plants by changes in plant practices are suggested, with estimates of the magnitude of the major reductions.
Linguistic experts as semantic tour guides
This article examines the phenomenon of linguists testifying as experts on meaning in legal disputes over the interpretation of statutes, contracts, transcripts of tape-recorded conversations, and other important legal texts before courts in the USA. It concludes that there is an important role for linguists in such cases -- the role of the tour guide. It suggests that judges need not be concerned about linguists usurping the traditional roles of the judge and the jury as ultimate interpreters provided that the linguist's testimony is appropriately circumscribed.
