Consumptive index systems

Here, r is the cumulative exergy consumption index for a specified product. For the manufacturing of major products, we have 17 < 1. Sometimes, for a byproduct we may have 17 > 1, if the exergy of the product is greater than the exergy of the substituted product of a certain process. It would not be useful to calculate 77 for certain products, such as cars and airplanes, because their usefulness results mainly from their system features, not from the chemical composition of their components. However, the calculation of r may be beneficial for all kinds of products, because the values of r can be used to compare various design variables and production technologies. [Pg.280]

The consumptive index. Cl reflects another aspect of preconcentration system efficiency. i.e.. efficiency of sample utilization. This concept, recently proposed by the Author (11], is defined as the volume of sample, in milliliters, consumed to achieve a unit F. and is expressed by the equation ... [Pg.15]

Taking into account the rationahty of harmoniousness evaluation indexes and the convenience of the quantification in practice, combined with the related indicators of the water conservancy statistics in China, the harmoniousness evaluation indexes are selected. In the social system, guarantee rate of residential, industrial, agricultural and bio-environmental water consumption can be selected. The harmoniousness evaluation index system of water resources allocation is shown in Table 1. [Pg.116]

Research has been done showing that rapid pressnre-driven LC analysis can be done with little solvent consumption, demonstrating this as a viable process analytical tool. Using electrokinetic nanoflow pumps LC can be miniaturized to the point of being a sensor system. Developments in terms of sampling to enable sampling directly from a process stream, to the separation channel on a chip are critical for the application of miniaturized process LC. The components (valves and pumps) required for hydrodynamic flow systems appear to be a current limitation to the fnll miniatnrization of LC separations. Detection systems have also evolved with electrochemical detection and refractive index detection systems providing increased sensitivity in miniaturized systems when compared to standard UV-vis detection or fluorescence, which may require precolumn derivatization. [Pg.535]

There have been some attempts to find chemical or physical correlates of short-term consumption that can be used as indices of biological lability (Amon et al., 2001). For example, there is indication that bioavailability (i.e., in terms of milligrams bacterial biomass per milligrams of DOC consumed) is correlated to the elemental composition in terms of C, N, H, and O, to the aliphatic contents, and to the overall degree of reduction of the DOM (Sun et al., 1997 Hopkinson et al., 1998 Hunt et al., 1999). However, there is still no general index that is applicable to all different aquatic systems, and it is unlikely that a single index will be able to account for variation in the multiple factors that simultaneously determine DOM... [Pg.418]

As previously reported, membrane contactors present interesting advantages with respect to traditional units. Moreover, they well respond to the main targets of the process intensification, such as to develop systems of production with lower equipment-size/production-capacity ratio, lower energy consumption, lower waste production, higher efficiency. In order to better identify the potentialities of membrane contactors in this logic, they have been recently compared to traditional devices for the sparkling-water production in terms of new defined indexes [24]. In particular, the comparison has been made at parity of plant capacity and quality of final product. The metrics used for the comparison between membranes and traditional units are ... [Pg.456]

Carcinogenicity has been used by the World Health Organization as an index for classifying mycotoxins [32]. However, the carcinogenic effects of very few mycotoxins have been established or even directly correlated. Therefore, this method of classifying mycotoxins may not be applicable at the present time. But as the carcinogenic risk of more mycotoxins is established based on ongoing research to identify the associations between human or animal consumption of contaminated food and the incidence of associated mycotoxicosis, this classification system may become very relevant. [Pg.173]

Fig. 11. The hemodynamic response to exercise is influenced by the p2-Ilel64 polymorphism in patients with heart failure. Exercise-induced changes were significantly lower in patients with Ilel64 for 02, stroke volume (SV), cardiac index (Cl), and systemic vascular resistance (SVR). All changes represent increases by the indicated percentage, except for SVR, which was a decrease. HR, heart rate. / < 0.05 vs Thrl64. V02 is maximal oxygen consumption.

As for enzyme-coupled reaction system, initial rate itself is estimated by kinetic analysis of reaction curve based on numerical integration and NLSF of calculated reaction curves to a reaction curve of interest. Consequently, neither the conversion of indexes nor the optimization of parameters for such conversion is required and the integration strategy can be realized easily. By kinetic analysis of enzyme-coupled reaction curve, there still should be a minimum number of the effective data and a minimum substrate consumption percentage in the effective data for analysis these prerequisites lead to unsatisfactory lower limits of linear response for favourable analysis efficiency (the use of reaction duration within 5.0 min). The classical initial rate method is effective to enzyme-coupled reaction systems when activities of the enzyme of interest are not too high. Therefore, this new approach for kinetic analysis of enzyme-coupled reaction curve can be integrated with the classical initial rate method to quantify enzyme initial rates potentially for wider linear ranges. [Pg.168]
