NEW REFRACTORY MATERIALS FOR THE COPPER INDUSTRY

Wear of various basic refractory materials to substitute to currently used magnesia chrome bricks has been studied, measuring matte and slag penetration and dissolution, through different cup and rotary slag tests. High magnesia with and without impregnation, magnesia graphite, magnesia-alumina spinel with and without impregnation, olivine-magnesia and olivine magnesia- graphite bricks, as well...

Imaging zinc: old and new tools.

As recently as 20 years ago, all zinc in biological systems was believed to be tightly bound to proteins, and the idea of imaging zinc was considered heretical. Beginning with Maske's research with dithizonate staining of the hippocampus in the 1950s, however, zinc-sensitive dyes have indicated that, in mammalian cells, free zinc can exist in at least three separate pools. These pools include v...

An Old Insight Leads to New Tools

seems an unlikely person to help transform the statistical rigor of experiments in the vanguard of microarray analyses and proteomics. For one thing, he died almost 250 years ago in Tunbridge Wells, an English town that remains sleepy even today. And rather than being a scientist, Bayes was a nonconformist minister. Yet today's microarray and proteomic researchers increasingly use the statistic...

Some old and some new statistical tools for outcomes research.

Outcomes research “seeks to understand the end results of particular health care practices and interventions”1 to inform the development of clinical practice guidelines, evaluate the quality of medical care, and foster effective interventions to improve the quality of care.2 Although randomized trial designs have been used to assess quality of care and to identify effective interventions in the...
