Straws of four ornamental flowers (carnation, rose, lily, and violet) were added into denitrification biofilters using gravel as matrix through vertically installed perforated polyvinylchloride pipes to provide organic carbon for the treatment of nitrate-contaminated wastewater operating in batch mode. Removal efficiencies of nitrate and phosphate, as well(More)
In this paper, we analyze the compatibility of Fong’s reduction and the Glauberman correspondence of characters and then clarify that the p-solvable hypothesis in a paper of Harris and Linckelmann is not necessary. Let O be a complete discrete valuation ring with an algebraically closed residue field k of characteristic p and a quotient field K of(More)
The main purpose of this paper is to prove that the extensions of a nilpotent block algebra and its Glauberman correspondent block algebra are Morita equivalent under an additional group-theoretic condition (see Theorem 1.6); in particular, Harris and Linckelman’s theorem and Koshitani and Michler’s theorem are covered (see Theorems 7.5 and 7.6).
