For positive integers N1,N2,...,Nn, let L = Z^n ＋ A and A =- N1Z x -…… x NnZ ＋ F be two rational periodic sets, where A ∩ （1/N1）Z x ... x （1/Nn）Z and F ∩ Z^n are finite sets with （A- A）∩Z^n = {0} and （F- F）N （N1Z x.. x NnZ） = {0}. In this note, we shall determine conditions under which the tiling set L has universal spectrum A. We first obtain a criterion of universal spectra. This criterion combined with the properties of compatible pair yields many necessary and sufficient conditions for A to be a universal spectrum for L. We then show that, under some mild additional conditions, the conjecture of Lagarias and Szab5 is true. The results here extend the corresponding results of Lagarias, Szabo and Wang.

The rate of nitrous oxide emission from a laboratory sequence batch reactor （SBR） wastewater treatment system using synthetic wastewater was measured under controlled conditions. The SBR was operated in the mode of 4 h for aeration, 3.5 h for stirring without aeration, 0.5 h for settling and drainage, and 4 h of idle. The sludge was acclimated by running the system to achieve a stable running state as chemical oxygen demand, NO2^-, NO3^-, NH4^＋, pH, and N2O. indicated by rhythmic changes of total N, dissolved oxygen, Under the present experimental conditions measured nitrous oxide emitted from the off-gas in the aerobic and anaerobic phases, respectively, accounted for 8.6%-16.1% and 0-0.05% of N removed, indicating that the aerobic phase was the main source of N2O emission from the system. N2O dissolved in discharged water was considerable in term of concentration. Thus, measures to be developed for the purpose of reducing N2O emission from the system should be effective in the aeration phase.

The aim of this paper is to investigate the size properties of a planar set whose distance set has some prescribed arithmetic combinatorics. Such research is motivated by the conjecture that the disk has no more than 3 orthogonal exponentials. By proving a shifted version of ErdSs-Solymosi＇s theorem on the distance sets, we give some grounds on the conjecture. The results obtained here extend the corresponding results of Iosevich and Jaming in a simple manner.
