Technological-economic indexes

The system s hydraulic resistance, mainly the absorption device, is a very important parameter affecting the economic index of the technology because a huge amount of flue gas is emitted from the power plant. To evaluate the hydraulic resistance of the equipment, the pressure drop Ap, between Points A and B shown in Fig. 7.11, is measured in each run. 

Directions and norms of technological designing and technical-and-economic indexes of a power equipment of the factories of ferrous metallurgy. Metal works. T. 18. It is sewn up aerospheres. Clearing of gases of a dust. Sanitary codeno 1-41-00. SSSR. 2001. 

Moreover, reaction parameters must be selected that will produce more or less complete transformations within the technologically available time, i.e. when the maximal value of rin the fimction n = necessary for finishing the process, does not exceed a limit, set by technological, economic or any other reasons. At the same time, the minimal value of r, at which transformation of the refractive index may be detected (i.e. the induction period of the transformation), is several minutes long. 

The objective of any sea water conversion process is twofold to produce a demineralized water whose quality is adequate for the proposed use, and to produce this water at as low a cost as possible. In considering any new conversion process, after the establishing of the scientific and technologic soundness of the method, the question to be answered is the probable relative economics of the proposed process as compared to other processes, either actual (preferable) or proposed. One method of making this comparison is to prepare cost estimates. However, in some cases, such as this one, other indexes can be used. 

They are technologically easier to construct than conventional planar waveguides and the fabrication processes are more economic and rugged. Conventional waveguides need thicker substrates (10 times thicker) than ARROW structures to reach equivalent losses in this layer. Moreover, they are less suitable to develop optical sensors based on the core propagation, because if the membrane refractive index was the same, a thickness of about 100 nm would be needed to achieve single-mode behavior in the transversal direction to the layers. ARROWS have a 4-pm-thick core,... 

We seek to determine an optimal composition of a multicomponent solvent utilized to remove hydrocarbons from yeast. The major index of purification here is the hydrocarbon content in biomass upon extraction (y). For technological and economic reasons, the experimental design is accomplished in a local section of the concentration, Fig. 3.23. 

These four indexes reflect the business operation of enterprises from four aspects the growth, age composition of employees, investment strength in technological development, and economic benefit. They represent the four dimensions of commercial age.
