-
(IOP Publishing Ltd, 2018)Detailed chemical abundance distributions for 14 elements are derived for eight high-probability stellar members of the solar metallicity old open cluster M67 with an age of similar to 4 Gyr. The eight stars consist of ...

-
(Elsevier, 2016)The Principal Cordillera of Central Chile is characterized by two belts of different ages and lithologies: (i) an eastern Mesozoic belt, consisting of limestone- and gypsum-rich sedimentary rocks at the border between ...
-
(Georg Thieme Verlag Kg, 2020)Candida albicans is the most common human fungal pathogen, and with the increase in resistance rates worldwide, it is necessary to search for new pharmacological alternatives. Lavandula dentata L. essential oil is recognized ...
-
(PERGAMON-ELSEVIER SCIENCE LTD, 2007-04)Fine titanium dioxide particles were hydrothermally treated in a sodium hydroxide aqueous solution. The treatment extended from 1 to 6 days leading to belt-like and wire-like structures of a metastable phase of sodium ...

(Elsevier, 2007)Fine titanium dioxide particles were hydrothermally treated in a sodium hydroxide aqueous solution. The treatment extended from 1 to 6 days leading to belt-like and wire-like structures of a metastable phase of sodium ...
-
(Elsevier B.V., 2019)The Chilean bottled water market has experienced continuous growth since 2000, surpassing 500 million liters sold in 2015. Generally, consumers tend to associate the consumption of bottled water with a healthy lifestyle, ...
-
(ESO, 2015)Aims. Our goal is to determine the molecular composition of the circumstellar disk around AB Aurigae (hereafter, AB Aur). AB Aur is a prototypical Herbig Ae star and the understanding of its disk chemistry is paramount for ...
-
(IOP Publishing, 2017)Chemical abundances of eight O-and B-type stars are determined from high-resolution spectra obtained with the MIKE instrument on the Magellan. 6.5 m Clay telescope. The sample is selected from 42 candidates for membership ...
-
(Institute of Physics Publishing, 2018)The central region of the massive star-forming cloud G33.92+0.11 was investigated with the emission from the deuterated species HDCS and DCN observed at sub-arcsecond angular resolution (∼0 7) using ALMA. HDCS shows a ...

-
(IOP PUBLISHING LTD, 2008-03)Ca (II) triplet spectroscopy has been used to derive stellar metallicities for individual stars in four Large Magellanic Cloud fields situated at galactocentric distances of 3 degrees, 5 degrees, 6 degrees, and 8 degrees ...
-
(IOP PUBLISHING, 2008-09)We present stellar metallicities derived from Ca II triplet spectroscopy in over 350 red giant branch stars in 13 fields distributed in different positions in the Small Magellanic Cloud, ranging from similar to 1 degrees ...
-
(The American Astronomical Society, 2022)We show the results of a study using the spectral synthesis technique study for the full MaNGA sample showing their chemical enrichment history (ChEH) as well as the evolution of the stellar mass-metallicity relation (MZR) ...
-
(Springer Verlag, 2019)© 2018, Springer-Verlag GmbH Germany, part of Springer Nature. Distributed applications are challenging to program because they have to deal with a plethora of concerns, including synchronization, locality, replication, ...
-
(Institute of Physics Publishing, 2018)We present molecular line observations of the high-mass molecular clump IRAS 16562−3959 taken at 3 mm using the Atacama Large Millimeter/submillimeter Array (ALMA) at 1. 007 angular resolution (0.014 pc spatial resolution). ...
-
(Elsevier, 2021)In this work we present a version of the so called Chen and Chv´atal’s conjecture for directed graphs. A line of a directed graph D is defined by an ordered pair (u, v), with u and v two distinct vertices of D, as the ...
-
(Academic Press-Elsevier, 2017)This paper presents a novel form of selecting the likelihood function of the standard sequential importance sampling/re-sampling particle filter (SIR-PF) with a combination of sliding window smoothing and chi-square statistic ...
-
(Elsevier Ltd, 2019)A National Immunization Technical Advisory Group (NITAG) provides independent, evidence–based recommendations to the Ministry of Health for immunization programmes and policy formulation. In this article, we describe the ...
-
(Nature Publishing Group, 2018)Fundamental processes of the seismic cycle in subduction zones, including those controlling the recurrence and size of great earthquakes, are still poorly understood. Here, by studying the 2016 earthquake in southern ...
