The initial stages of cave formation: Beyond the one-dimensional paradigm
, 2010 The solutional origin of limestone caves was recognized over a century ago, but the short penetration length of an undersaturated solution made it seem impossible for long conduits to develop.

Study of the microstructure resulting from brazed aluminium materials used in heat exchangers [PDF]
, 2005 Re-solidification of AA4343 cladding after brazing as well as the related precipitation in the modified AA3003 core material have been investigated. Analysis of the re-solidified material showed that partial dissolution of the core alloy occurs in both ...

Photoreductive Dissolution of Iron Oxides Trapped in Ice and Its Environmental Implications [PDF]
, 2010 The availability of iron has been thought to be a main limiting factor for the productivity of phytoplankton and related with the uptake of atmospheric CO_2 and algal blooms in fresh and sea waters. In this work, the formation of bioavailable iron (Fe(II)

Uncertainties in (E)UV model atmosphere fluxes
, 2008 During the comparison of synthetic spectra calculated with two NLTE model atmosphere codes, namely TMAP and TLUSTY, we encounter systematic differences in the EUV fluxes due to the treatment of level dissolution by pressure ionization.
