Effect of soil moisture on the response of soil respiration to open-field experimental warming and precipitation manipulation
(
Multidisciplinary Digital Publishing Institute (MDPI)
, 2017 , Article)
Soil respiration (RS, Soil CO2 efflux) is the second largest carbon (C) flux in global terrestrial ecosystems, and thus, plays an important role in global and regional C cycling; moreover, it acts as a feedback mechanism ...
Dynamics of charge evolution in glass capillaries for 230-keV Xe23 + ions
(
American Physical Society
, 2012 , Article)
We have measured the transmission of 230-keV (10-keV/q) Xe23+ ions through insulating tapered glass capillaries of microscopic dimensions. The dynamics of charging and discharging processes have been investigated, evidencing ...
