Sentence examples for net useful from inspiring English sources

· Available heat or maximum net useful heat that can be evaluated as mechanical exergy.

This formulation would be suitable to evaluate either the net useful work or the net useful heat of a system being both the outcome of available energy, considering the role of pressure other than temperature, in the evaluation of work and heat interactions in combination with a reservoir as defined in the study of Gyftopoulos and Beretta[1].

As a consequence of the concept of interconvertibility (Gaggioli et al.[5, 6, 7]): 'useful work is not better than useful heat, and the available energy results in maximum net useful heat or, equivalently, maximum net useful work or the combination of both'.

The curves show a low value of limiting current for all the catalyst samples, probably because of the defects present on the CNTs [as is clear from the high value of I D/I G (Raman data)]which may give rise to unwanted side reactions, thus lowering the net useful current.

Thus, the definition of mechanical exergy that represents, in this case, the maximum net useful heat obtained from the available energy in infinitesimal terms may be expressed by the following relationship: d E X M = δ Q REV NET = δ Q REV CONVER + δ Q REV TRANSF Open image in new window (16).

By virtue of the concepts of equivalence and interconvertibility conceived by Gaggioli et al.[5, 6, 7], the available energy of a system results in two outcomes: · Available work or maximum net useful work that can be evaluated as thermal exergy.

Trend No. 3: The Mobile Net Becomes Useful.

The mathematical function we obtained from the net seems useful in determining the relative importance of single variables related to survival.

Petri nets are useful for mathematically modelling disease-causing genetic epistasis.

Moreover we show that Petri Nets are useful in biochemical networks representation and for steady state pathways identification.

Although, very little is known about AFP in NETs, some useful data already exist on the expression and value of α- and β-subunits of hCG (Heitz et al, 1987; Eriksson et al, 1989; Grossmann et al, 1994; Nobels et al, 1997).
