The structure and rate of late Miocene expansion of C-4 plants: Evidence from lateral variation in stable isotopes in paleosols of the Siwalik Group, northern Pakistan
(GEOLOGICAL SOC AMER, 2007-11)
This study uses stable isotope variation within individual Mio-Pliocene paleosols to investigate subkilometer-scale phytogeography of late Miocene vegetation change in southeast Asia between ca. 8.1 and 5 Ma, a time interval ...
Temporal changes in phytoplankton productivity over the last ∼200 years recorded from mejillones bay laminated sediments Sedimentos laminados de la bahía mejillones como registro de cambios temporales en la productividad fitoplanctónica de los últimos ∼20
(2009)
We analyzed the contents of total organic carbon, biogenic opal, chlorins, and alkenones (as productivity proxies) from a laminated sediment core recovered within Bahía Mejillones, northern Chile, in order to reconstruct ...
Infarto agudo de miocardio sin enfermedad coronaria ateroesclerótica obstructiva: utilidad de las imágenes intravasculares y resonancia cardíaca en su diagnóstico
(Sociedad Médica de Santiago, 2020)
Background: Myocardial infarction with non-obstructive coronary artery disease (MINOCA) is common. Cardiac magnetic resonance (CMR) and intravascular imaging (IVI) may be useful for establishing its etiology. Aim: To ...
Paleolimnological reconstruction of the centennial eutrophication processes in a sub-tropical South American reservoir
(Elsevier, 2020)
Reservoirs hold a detailed record of the changes in the input of sediments and nutrients over decades to centuries. Paleolimnological multi-proxy analysis makes it possible to reconstruct baseline conditions to infer early ...
Two Zn(II) and one Mn(II) complexes using two different hydrazone ligands: spectroscopic studies and structural aspects
(SPRINGER/PLENUM PUBLISHERS, 2008-04)
Three new coordination complexes of Zn(II)
and Mn(II) have been synthesised using two different tridentate
N,N,O donor hydrazone ligands, Hpbh and Hacpbh
respectively. The complexes [Zn(pbh)2] (1) and [Zn
(acpbh)2] (2) ...
Resistivity induced by a rough surface of thin gold films deposited on mica
(ELSEVIER, 2005-03-16)
A central question regarding thin metallic films is how does the roughness of the film affect its electrical transport properties, when its thickness is comparable to or smaller than the electron mean free path. The drive ...
Evidence of the Disassembly of alpha-Cyclodextrin-octylamine Inclusion Compounds Conjugated to Gold Nanoparticles via Thermal and Photothermal Effects
(MDPI, 2016)
Cyclodextrin (CD) molecules form inclusion compounds (ICs), generating dimers that are capable of encapsulating molecules derived from long-chain hydrocarbons. The aim of this study is to evaluate the structural changes ...
Inversion of the spin-torque effect in MTJs via resonant magnon scattering
(Institute of Electrical and Electronics Engineers Inc., 2020)
Gravity derived depth to basement in Santiago Basin, Chile: implications for its geological evolution, hydrogeology, low enthalpy geothermal, soil characterization and geo-hazards
(Servicio Nacional Geología Minerva, 2015)
A recording of 1,115 gravimetric stations, the review of 368 wells, and the petrophysics measurements of 106 samples from representative outcrops have been used for a comprehensive geological/geophysical study of Santiago ...
New Highly Charged Iron(III) Metal−Organic Cube Stabilized by a Bulky Amine
(American Chemical Society, 2020)
In this work, we report a new octanuclear cluster based on FeIII and the ligand 1H-imidazole-4,5-dicarboxylic acid, [Et3NH](12)[Fe-8(IDC)(12)]center dot 10DMF center dot 13H(2)O (1), with a metal core containing eight ...
