Testing the Accuracy of the Cell-Set Model Applied on Vane-Type Sub-Boundary Layer Vortex Generators
(MDPI, 2021-03-11)
Vortex Generators (VGs) are applied before the expected region of separation of the boundary layer in order to delay or remove the flow separation. Although their height is usually similar to that of the boundary layer, ...
Quartz chemistry of granitic pegmatites: Implications for classification, genesis and exploration
(Elsevier, 2021-12-05)
[EN]Quartz from 254 pegmatites representing eight pegmatite fields and provinces worldwide was investigated by laser-ablation inductively-coupled plasma mass spectrometry (LA-ICP-MS) to determine concentrations of trace ...
Electronic Surveillance and Security Applications of Magnetic Microwires
(MDPI, 2021-04-30)
Applications in security and electronic surveillance require a combination of excellent magnetic softness with good mechanical and anticorrosive properties and low dimensionality. We overviewed the feasibility of using ...

(Cambridge University Press, 2021-04-12)
[EN] Background. Faced with the situation of COVID-19, teachers are dealing with new measures,
insecurity and a lack of clear guidelines. The aim of this study is to analyse the levels of stress,
anxiety and depression ...
VinegarScan: A Computer Tool Based on Ultraviolet Spectroscopy for a Rapid Authentication of Wine Vinegars
(MDPI, 2021-10-22)
Ultraviolet-visible (UV-vis) spectroscopy has shown successful results in the last few years to characterize and classify wine vinegar according to its quality, particularly those with a protected designation of origin ...
FODMAP Intake in Spanish Population: Open Approach for Risk Assessment
(MDPI, 2020-08-13)
Fermentable oligo-, di- and monosaccharides and polyols’ (FODMAP) were related with intestinal complications. The present study aimed to determine the FODMAP consumption of Spanish children, adolescents and adults, analyzing ...
Ni-Mn-Sn-Cu Alloys after Thermal Cycling: Thermal and Magnetic Response
(MDPI, 2021-11-13)
Heusler Ni-Mn-Sn-based alloys are good candidates for magnetic refrigeration. This application is based on cycling processes. In this work, thermal cycles (100) have been performed in three ribbons produced by melt-spinning ...
Cross-Validation of Predictive Equation for Cardiorespiratory Fitness by Modified Shuttle Walk Test in Adults with Schizophrenia: A Secondary Analysis of the CORTEX-SP Study
(MDPI, 2021-10-29)
Cardiorespiratory fitness (CRF) can be direct or estimated from different field tests. The Modified Shuttle Walk Test (MSWT) is suitable for all levels of function, allowing a peak response to be elicited. Therefore, we ...
Neurocognitive, social cognitive, and clinical predictors of creativity in schizophrenia
(Pergamon-Elsevier, 2020-10)
Background: Creativity is considered an essential human accomplishment and a key component for daily life problem solving. It has been suggested that impairment in working memory, cognitive flexibility, and theory of mind ...
The Tres Arroyos Granitic Aplite-Pegmatite Field (Central Iberian Zone, Spain): Petrogenetic Constraints from Evolution of Nb-Ta-Sn Oxides, Whole-Rock Geochemistry and U-Pb Geochronology
(MDPI, 2020-11-12)
Abundant Li-Cs-Ta aplite-pegmatite dykes were emplaced in the western Central Iberian Zone of the Iberian Massif during the Variscan Orogeny. Their origin and petrogenetic relationships with the widespread granitoids have ...
