(ELSEVIER SCIENCE BV, 2005-01-03)Ar-40/Ar-39 geochronological method is applied to date both emplacement and subsequent very low-grade metamorphism of a thick lava series, the Veta Negra Formation from the Cordon de Chacana area, in the Coastal Range of ...
-
(EDP SCIENCES, 2016)Context. Independent distance estimates are particularly useful to check the precision of other distance indicators, while accurate and precise masses are necessary to constrain evolution models. Aims. The goal is to ...
-
(ELSEVIER, 2004)This article deals with the numerical approximation of Navier-Stokes equations in a domain with moving boundaries. Using the arbitrary Lagrangian-Eulerian (ALE) method we transform the problem from a moving domain to a ...
-
(IEEE Computer Society, 2018)E-coaching systems are a highly valuable asset for promoting healthier lifestyles. However, the design of these systems is intrinsically complex. This article proposes a loosely coupled architecture to support the modeling ...
-
(Slovak Acad Sciences Inst Informatics, 2015)Several researchers have identified the design of collaborative systems as a particularly challenging task, because it has to consider services that are not easily identifiable by software designers. The systems that ...

Are returns to scale with variable network size adequate for transport industry structure analysis? (INST OPERATIONS RESEARCH MANAGEMENT SCIENCES, 2006-08)It is customary to analyze transport industry structure using two indices: (1) economies of density and (2) economies of scale with variable network size. The latter has been defined to analyze the behavior of costs when ...

-
(EDP Sciences, 2003-03)We present K-band imaging observations of ten gamma-ray burst (GRB) host galaxies for which an optical and/or radio afterglow associated with the GRB event was clearly identified. Data were obtained with the Very Large ...
-
(Cambridge University Press, 2019)Glaciers on active volcanoes are subject to changes in both climate fluctuations and volcanic activity. Whereas many studies analysed changes on individual volcanoes, this study presents for the first time a comparison of ...
-
(Blackwell Publishing Ltd, 2019)Pharmacists are trusted health care professionals. Many patients use over-the-counter (OTC) medications and are seen by pharmacists who are the initial point of contact for allergic rhinitis management in most countries. ...

(Oxford, 2022)Accurately measuring stellar parameters is a key goal to increase our understanding of the observable universe. However, current methods are limited by many factors, in particular, the biases and physical assumptions ...
-
(Frontiers Media S.A., 2019)The entactogen MDMA (3,4-methylenedioxy-methamphetamine, “Ecstasy”) exerts its psychotropic effects acting primarily as a substrate of the serotonin transporter (SERT) to induce a non-exocytotic release of serotonin. ...
-
(SPRINGER/PLENUM PUBLISHERS, 2006-04)We consider a system of multicolour disordered lattice gas, following closely the (monocolour) introduced by Faggionato and Martinelli((3,4)). We study the projection on the monocolour system and we derive an estimate of ...
-
(I C D D R B-CENTRE HEALTH POPULATION RESEARCH, 2006-06)The problem of arsenic in Chile was reviewed. In Chile, the population is exposed to arsenic naturally via drinking-water and by air pollution resulted from mining activities. The sources of arsenic were identified to ...
-
(Taylor and Francis, 2020)Today (year 2020), the globally recognized problem of arsenic (As) contamination of water resources and other environments at toxic levels has been reported in all of the 20 Latin American countries. The present review ...
