Precipitation is the key determinant of topsoil δ15N values in southern Patagonia's semiarid rangelands
(Soil Science Society of AmericaEstados Unidos, 2022-02-11)
Nitrogen (N) cycling in rangeland soils could potentially be controlled by water supply, stocking rates, or a range of other variables, such as ecosystem N stocks. To gauge the relative importance and elucidate possible ...

Variation in camelid δ13C and δ15N values in relation to geography and climate: Holocene patterns and archaeological implications in central western Argentina
(Academic Press Ltd - Elsevier Science Ltd, 2016-02)
Camelids are among the largest wild and domestic faunas in South America and represent one of the most important taxa to pre-hispanic South America human populations. Stable isotope data from these animals play an important ...
Naturaleza de las interacciones Mδ+⋯δ+C-Oδ- EN carbonilos metálicos: Un estudio basado en la topología de la densidad de carga electrónica y su función laplacianaNature of Mδ+⋯δ+C-Oδ interactions in metal carbonyls: An electronic study based on the topology of the electron charge density distribution and its Laplacian Function
(Sociedade Brasileira de Química, 2016-07)
The nature of the metal-ligand interactions, in the [Ti(CO)6]2-, [V(CO)6]-, [Cr(CO)6], [Mn(CO)6]+, [Fe(CO)6]2+ and [Co(CO)6]3+ complexes has been studied by means of topological analyses of the electron charge density, ...
Consistence between πn Δ spin-3/2 gauge couplings and electromagnetic gauge invariance
(IOP Publishing, 2015-11)
We review the consistency between the recently proposed spin-3/2 gauge interaction for Δ resonance with nucleons (N) and pions (π), and the fundamental electromagnetic gauge invariance in any radiative amplitude. We show ...
