Contrasting Centennial‐Scale Climate Variability in High Mountain Asia Revealed by a Tree‐Ring Oxygen Isotope Record From Lahaul‐Spiti

open access: yesGeophysical Research Letters, 2020
Glacier response analyses in High Mountain Asia have revealed that the glaciers from the Karakoram region were in balance or thickening while most from the other regions were thinning, the “Karakoram anomaly.” It is, however, not clear whether this ...

Isotope effect in superconductors with coexisting interactions of phonon and nonphonon mechanisms

open access: yes, 2003
We examine the isotope effect of superconductivity in systems with coexisting interactions of phonon and nonphonon mechanisms in addition to the direct Coulomb interaction.

Solubility isotope effects in aqueous solutions of methane [PDF]

open access: yes, 2002
The isotope effect on the Henry's law coefficients of methane in aqueous solution (H/D and C-12/C-13 substitution) are interpreted using the statistical mechanical theory of condensed phase isotope effects.

Mass-spectrometric research of ion sputtering processes at high primary ion energies [PDF]

open access: yesЖурнал нано- та електронної фізики, 2009
The article is devoted to mass-spectrometric investigation of ion sputtering processes in a wide range of primary ion energies. For this purpose a design of the secondary neutral mass-spectrometer is developed, which unlike the traditional devices of the

Nitrogen fixation sensitivity related to water use efficiency at reproductive development in soybean

open access: yesPlant, Soil and Environment, 2020
Soybean [Glycine max (L.) Merr.] nitrogen fixation is sensitive differentially to drought among different genotypes at different growth and development stages, which directly affects soybean yield. Acetylene reduction activity (ARA) response to a gradual

Argon annealing of the oxygen-isotope exchanged manganite La_{0.8}Ca_{0.2}MnO_{3+y}

open access: yes, 2000
We have resolved a controversial issue concerning the oxygen-isotope shift of the ferromagnetic transition temperature T_{C} in the manganite La_{0.8}Ca_{0.2}MnO_{3+y}.

Analytical modelling of stable isotope fractionation of volatile organic compounds in the unsaturated zone

open access: yes, 2011
Analytical models were developed that simulate stable isotope ratios of volatile organic compounds (VOCs) near a point source contamination in the unsaturated zone. The models describe diffusive transport of VOCs, biodegradation and source ageing.
