Riesgos derivados de la presencia de residuos mineros: Disponibilidad de metales en minas abandonadas
(Sociedad española de la ciencia del suelo, 2010)
La minería en Andalucía ha dado lugar a la creación de entornos, formados por sólidos de desecho, que forman lo que se conoce como tecnosoles y que pueden contener elementos potencialmente tóxicos para los recursos ...

Optimizing the relaxation route with optimal control
(American Physical Society, 2021)
We look into the minimization of the connection time between nonequilibrium steady states. As a prototypical example of an intrinsically nonequilibrium system, a driven granular gas is considered. For time-independent ...

Existence and uniqueness theorem for slant immersions in Sasakian-space-forms
(Institute of Mathematics (University of Debrecen), 2001)
In this paper, we present the existence and uniqueness theorems for slant immersions into Sasakian-space-forms. By applying the first result, we prove several existence theorems for slant submanifolds. In particular, we ...

Latitudinal Trends in Human Primary Activities: Characterizing the Winter Day as a Synchronizer
(Scientific Reports, 2018-03-28)
This work analyzes time use surveys from 19 countries (17 European and 2 American) in the middle latitude (38–61 degree) accounting for 45% of world population in this range. Time marks for primary activities are contrasted ...

Comparative Study of Phenolic Profile, Antioxidant Capacity, and Color-composition Relation of Roselle Cultivars with Contrasting Pigmentation
(Springer Nature, 2016)
Roselle is a plant that accumulates anthocyanins significantly, hence its importance as food coloring and as a source of antioxidant compounds for human health. This study was aimed to determine phenolic composition and ...

Universal asymptotic behavior in nonlinear systems driven by a two-frequency forcing
(American Physical Society, 2013)
We examine the time-dependent behavior of a nonlinear system driven by a two-frequency forcing. By using a nonperturbative approach, we are able to derive an asymptotic expression, valid in the long-time limit, for the ...

Morfología y dimorfismo sexual de la pelvis de Pitymys duodecimcostatus
(CSIC - Estación Biológica de Doñana (EBD), 1974-12)
The pelvis of 87 specimens (39 females and 48 males) of Pitymys duodecimcostatus were examined to find morphological and biometrical features allowing the identification and sex determination of remains found in owl ...

Anisotropic lattice expansion determined during flash sintering of BiFeO3 by in-situ energy-dispersive X-ray diffraction
(Elsevier, 2019)
BiFeO3 has a Curie temperature (TC) of 825 °C, making it difficult to sinter using conventional methods while maintaining the purity of the material, as unavoidably secondary phases appear at temperatures above Tc. Flash ...
