Theoretical matrix elements, for the ground-state to ground-statetwo-neutrino double-beta-decay mode(2 nu }beta -beta of Te128,130isotopes, are calculated within a formalism that describes interactionsbetween neutrons in...

We investigate the use of Hg as a proxy for volcanism by studying four distal and two proximal sections in relation to the Deccan volcanic center, straddling the Cretaceous-Paleogene (KPg) boundary at (a) Højerup (Denma...

Stable oxygen isotopes (d18O) from human bone apatite from central western Argentina (30º–37ºS latitude) were analysed to understand changes in human residential mobility during the Late Holocene. This region contain...

On the basis of their thermal preferences, salmon introduced in South America can distribute over the whole Southern Patagonian Shelf Ecosystem (SPSE). Stable isotope (δ13C and δ15N) data show that the SPSE is dominate...

(〖E(8〗_1^+))/(〖E(2〗_1^+)),(〖E(6〗_1^+))/(〖E(2〗_1^+)) , ( 〖E(4〗_1^+))/(〖E(2〗_1^+)) and the ratios of In this study, the energy of the first exited 21+ for 152-156DY even-even isotopes are compared ...

There are various geotectonic interpretations of the origin of the Eastern Magmatic Belt as part of the Lower Paleozoic Orogen at the Southwestern Gondwana margin in the Puna, NW Argentina. In this research paper, we obt...

Abstract Background Microhabitat heterogeneity plays a crucial role in shaping plant water use strategies and ecophysiological processes in arid ecosystems, yet little is known about the coupled response of leaf water is...

Ground states bands (GSB) and negative parity band (NPB) of  isotopes have been calculated. Bohr-Mottelson (BM), Interacting boson approximation-1(IBM-1) and Interacting vector boson model (IVBM) were used for this purp...

The Neuquén Basin is a stratigraphically- and economically-important Early Cretaceous depocentre located in west-central Argentina. The Early Valanginian to Early Barremian succession (upper Vaca Muerta, Mulichinco and ...

The Ediacaran Period (635-542 Ma) witnessed a series of extraordinary events. It arises with the end of the Marinoan Glaciation and deposition of worldwide enigmatic cap carbonate deposits. This abrupt shift in paleoclim...

En este trabajo se presentan los valores isotópicos de carbono y nitrógeno obtenidos en especímenes de roedores correspondientes a la familia Chinchillidae de contextos arqueológicos del sitio Quebrada Seca 3 (QS3, A...

Latest Maastrichtian climate change caused by Deccan volcanism has been invoked as a cause of mass extinction at the Cretaceous-Paleogene (K-Pg) boundary (~66.0 Ma). Yet late Maastrichtian climate and ecological changes...

Lu-Hf isotope data are presented for dated Permian zircon grains from six samples of the latest Palaeozoic to Jurassic low-grade metasedimentary rocks of western Patagonia and the northern Antarctic Peninsula, as well as...

Constraining the influence of different moisture sources across the flanks of mountain ranges is important for understanding tectonic, geomorphic, and paleoclimate problems at geologic timescales, as well as evaluating c...

The Precordillera terrane (Cuyania) in western Argentina is commonly accepted as an exotic fragmentderived from Laurentia in the Early Paleozoic. Evidence supporting such an interpretation is manly basedon similarities i...

In this paper we illustrate the stratigraphy, geochronology, and geochemistry (major, minor, trace elements and Sr-isotopes) of a Holocene tephra layer found within coastal sedimentary deposits north of Caleta Olivia (Sa...

The choice of sampling method is essential in the development of a population genetic study. This choice influences the type of samples that can be obtained and, therefore, the quality of the extracted DNA. Sampling meth...

Gowertetal. (2025) reported the presence of an adult female Chinook salmon (Oncorhynchust shawytscha) in the Patos Lagoon, Brazil. The authors presented their findings as ‘the firsts cientific record’ of non-native C...

Abstract Tin is a critical metal predominantly sourced from granite-associated deposits linked to anatexis of metasedimentary rocks and extreme magmatic differentiation. However, how metamorphism of sedimentary protolith...

Abstract Rubidium, cesium, strontium, barium and their isotopes are employed as tracers of magmatic differentiation and fluid-mediated metasomatism, but their mobility during mineral-scale alteration remains uncertain. H...

The purpose of this study was to assess hydrological controls (e.g., rainfall, irrigation practices, river discharge, dam operation, evaporation) on surface (SW)- ground water (GW) interactions in an irrigated valley wit...

Abstract Anthropogenic emissions may drive the isotopically light zinc that pervades the low-latitude upper ocean, but major gaps in our understanding of oceanic zinc cycling have hindered the unequivocal detection of an...
