Effects of the various concentrations of salt (0.5–12 g/L NaCl), surfactants (0.005–0.12 g/L LAS), and their co-presence on fermentative volatile fatty acids (VFAs) production from kitchen wastewater were investigated. VFAs production declined by 17–84% with increasing salt concentration...

We consider the bicriteria scheduling problem of minimizing the number of tardy jobs and average flowtime on a single machine. This problem, which is known to be NP-hard, is important in practice, as the former criterion conveys the customer's position, and the latter reflects the manufacturer's...
