Preliminary Investigation on Rapid Potassium Efflux from Activated Sludge in Response to Use of Peroxyacetic Acid
PublicationPreliminary research on activated sludge potassium efflux (GGKE - glutathione-gated potassium efflux) as a result of peroxyacetic acid (PAA) dosing were performed. Similarily as in case of chlorine dosing the PAA dosing causes initiation of bacteria defense mechanisms, related to the transformations of glutathione tripeptide, resulting in the increase of potassium ions concentration in the activated sludge environment. In the range...

Bounds on the cover time of parallel rotor walks
PublicationThe rotor-router mechanism was introduced as a deterministic alternative to the random walk in undirected graphs. In this model, a set of k identical walkers is deployed in parallel, starting from a chosen subset of nodes, and moving around the graph in synchronous steps. During the process, each node successively propagates walkers visiting it along its outgoing arcs in round-robin fashion, according to a fixed ordering. We consider...

MgPdSb─An Electron-Deficient Half-Heusler Phase
PublicationThe half-Heusler family consists of many semiconducting intermetallic compounds, virtually all of them having a valence electron count (VEC) of 18. We have studied an electron-deficient (VEC = 17) phase MgPdSb and its Pd-stuffed variant MgPd1.25Sb. The cubic F4̅3m crystal structure was confirmed by the Rietveld refinement of powder X-ray diffraction (XRD) data. The lattice parameter is a = 6.284 and 6.335 Å for MgPdSb and MgPd1.25Sb,...
