Reuse of water treatment residuals from lime softening, Part I: Applications for the reuse of lime sludge from water softening

Lime sludge, an inert material mostly composed of calcium carbonate, is the result of softening hard water before distribution as drinking water. A large city such as Des Moines, Iowa, produces about 32 000 tons of lime sludge (dry-weight basis) annually. This is about half of the lime sludge produced in Iowa per year in eight different cities, and these cities currently have 371 800 tons (dry-...

IISG Projects - Water for Our Future

For more than 100 years, the wetland sediments at the Indiana Dunes National Lakeshore (IDNL) and adjacent Indiana Dunes State Park have received atmospheric input of trace metals from industrial sources located upwind and to the west. The objective of this study was to document the extent and magnitude of this trace metal pollution both aerially and with depth within the IDNL, and to identify ...

Lime

Lymphocyte membrane rafts contain molecules critical for immunoreceptor signaling. Here, we report identification of a new raft-associated adaptor protein LIME (Lck-interacting molecule) expressed predominantly in T lymphocytes. LIME becomes tyrosine phosphorylated after cross-linking of the CD4 or CD8 coreceptors. Phospho-LIME associates with the Src family kinase Lck and its negative regulato...

This article examines three contemporary Australian poems that concern themselves with matters of the sacred within the modern Australian city. Noting that Australian poetry and the sacred have often been studied in terms of the landscape, the article approaches these poems as part of an undercurrent of spiritual or sacred writing that takes up urban Australian spaces as important and resonant ...
