Land use of sewage sludge is the primary disposal method in Shanxi, accounting for 42.66% of all. To determine the ecological risk of heavy metals in sewage sludge, contents of seven heavy metals in sewage sludge from 9 municipal waste water treatment plants (WWTPs) that had the highest application for land use were determined. The order of the measured concentrations was: Zn > Cr > Cu > Ni > P...

The aim of this study is to relate spectral realization of vowels and prosodic hierarchy in continuous speech. The IRISA speech alignment system is used and formant values of oral vowels are automatically measured in a total of 500,000 segments from around 30 hours of journalistic broadcast speech in French. The link between the duration of vowels and their spectral realization (through their f...

the aim of this study was to use ahp method to rank the obstacles to improving professional ethics in sport media. in the first step, the existing obstacles were identified by review of literature, searching the authentic websites and finally interview with sport media experts. after this step, the hierarchy tree was portrayed to rank the obstacles and then the analytical hierarchy process (ahp...

In [CS-92] we studied the agreement of operators Plogi and ACi−1 acting on NP . In this article we extend this work to other classes of the polynomial time hierarchy. We show that on Σk , Π P k , ∆ P k and Θ P k -classes both operators have the same behaviour, but this coincidence does not seem to be true on other classes included in the PH hierarchy: we give a set A such that, relativized to A...

We show that some natural re nements of the Straubing and Brzozowski hierarchies correspond (via the so called leaf-languages) step by step to similar re nements of the polynomial-time hierarchy. This extends a result of H.-J. Burtschik and H. Vollmer on relationship between the Straubing and the polynomial hierarchies. In particular, this applies to the boolean hierarchy and the plus{hierarchy.
