The possibility of carbon (C) being locked away from the atmosphere for millennia is given in hydromorphic soils. However, the water-table-dependent feedback from soil organic matter (SOM) decomposition to the climate system is less clear. At least three greenhouse gases are produced: carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O). These gases show emission peaks at different water...

BACKGROUND The refrigerant liquids and gases used widely in industry, farming and medicine for their cooling properties may cause severe frostbite. Despite their widespread use, only a few reports on frostbite of the hand involving these liquids and gases have been published. In this study, the circumstances accompanying these injuries, several adjunctive therapies and preventive measures are d...

Sonoluminescence from alkali-metal salt solutions has been studied because emission mechanism from non-volatile alkali-metal ions has been interested. We measured multi-bubble sonoluminescence spectra from KCl solutions saturated with Ar, Xe and He gases at temperatures in the range of 15 40 °C at the frequency of 148 kHz. For Arsaturated solutions, the spectral line width of K atom emission, w...
