Mineralogy and uranium leaching of ores from Triassic Peribaltic sandstones

The recovery of uranium and other valuable metals from Polish Peribaltic sandstones were examined. The solid-liquid extraction is the first stage of the technology of uranium production and it is crucial for the next stages of processing. In the laboratory experiments uranium was leached with efficiencies 71-100 % by acidic lixiviants. Satisfactory results were obtained for the alkaline leachin...

Budget referendums and government spending: evidence from Swiss cantons

In many Swiss cantons, new government programs must be approved by a referendum of citizens before money can be spent. Referendums seem like a natural way to address citizen–legislator agency problems, yet statistical evidence on how referendums affect spending decisions is almost nonexistent. We estimate regressions for Swiss cantons using panel data from 1980 to 1998 and find that mandatory r...

Pesticide Leaching from Agricultural Fields with Ridges and Furrows

In the evaluation of the risk of pesticide leaching to groundwater, the soil surface is usually assumed to be level, although important crops like potato are grown on ridges. A fraction of the water from rainfall and sprinkler irrigation may flow along the soil surface from the ridges to the furrows, thus bringing about an extra load of water and pesticide on the furrow soil. A survey of the li...
