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...
