متن کاملThermal electric ice-core drills: history and new design options for intermediate-depth drilling
Ice coring of temperate and polythermal glaciers demonstrates some limitations of most electromechanical (EM) and thermal electric (TE) drills. Most TE drills are heavy, require a heavy power system, work slowly and cannot operate in boreholes going through the cold–temperate ice transition. Antifreeze thermal electric drills (ATED) are capable of operating in polar ice caps, polythermal and te...
متن کاملRecovery of Cu(II) by chemical reduction using sodium dithionite.
Wastewaters containing Cu(II) along with ligands are ubiquitous in various industrial sectors. Efficacy of treatment processes for copper removal, especially precipitation, is greatly debilitated by ligands. Chemical reduction being commonly employed for production of metal nanoparticles has also been used for removing copper. Addition of ammonia was reported to be essential for improving coppe...
متن کاملUsing home schooled children in emergency management drills.
The need to make emergency drills as realistic as possible presents problems in children's hospitals because of the difficulties that exist in recruiting and using children to act as casualties. In this article, the author describes one approach, the use of home school children and their parents, that proved highly successful in conducting a drill involving a school bus accident and possible ch...
متن کاملChemical Recovery in TEMPO Oxidation
To be regarded as environmentally friendly and economical, an industrial process using 2,2,6,6-tetramethylpiperidine 1-oxyl (TEMPO) oxidation requires recycling and/or recovery of chemicals. In this work, hypochlorite recycling via electrolysis was evaluated and potential means for TEMPO recovery were explored. The most important variable affecting electrochemical hypochlorite conversion was th...
