TL;DR: Analysis of results suggest that the DCB theory best explains the role of cations and suggests that activated sludge systems should attempt to lower the ratio of monovalent to divalent cations to improve floc properties and treatment performance.

TL;DR: SDS PAGE results revealed the presence of a single protein in the exocellular biopolymer extract from municipal, industrial, and laboratory activated sludge samples, and Amino acid analysis and amino acid sequencing results suggested the protein was a Lectinlike protein, and binding site inhibition studies demonstrated that the protein had lectinlike activity.

TL;DR: In this article, the authors examine the performance of 160 pharmaceutical acquisitions from 1994 to 2001 and find evidence that on average acquirers realize significant positive returns, positively correlated with prior acquirer access to information about the research and development activities at target firms and a superior negotiating position.

TL;DR: In this article, the authors examined the performance of acquirers of 160 biotechnology firms from 1994-2001 and found evidence that on average, the acquirer of biotech firms realize significant positive returns.

TL;DR: In this paper, the effect of cations on the settling and dewatering of activated sludge was investigated using laboratory scale sludge reactors, and three parameters were investigated, i.e., the calcium to magnesium ratio, increasing divalent cation ratios, and increasing monovalent cation ratio.
