Weathering processes and natural radionuclides
(2011-12-01)
In managing our hydrological systems, increasing use is being made of information generated from studies held for understanding the controls on chemical weathering due to its importance in affecting the evolution of the ...
Calling activity patterns in an anuran assemblage: the role of seasonal trends and weather determinants
(2008)
Calling activity of anuran assemblages were related to seasonal changes in weather factors such as temperature and rainfall. We evaluated the suitability of these variables as determinants of activity of an assemblage and ...
Three frontside full halo coronal mass ejections with a nontypical geomagnetic response
(American Geophysical Union, 2009-06)
Forecasting potential geoeffectiveness of solar disturbances (in particular, of frontside full halo coronal mass ejections) is important for various practical purposes, e.g. for satellite operations, radio communications, ...
