Hábitos de uso de Internet en niños y niñas de 8 a 12 años: un estudio descriptivo
La irrupción de la Web 2.0 ha supuesto la aparición de nuevas formas de producir, distribuir, intercambiar y recibir información a través de medios electrónicos. En este contexto, es necesario alfabetizar a la población ... -
Hardening of cobalt ferrite nanoparticles by local crystal strain release: implications for rare earth free magnets
In this work, we demonstrate that the reduction of the local internal stress by a low-temperature solvent-mediated thermal treatment is an effective post-treatment tool for magnetic hardening of chemically synthesized ... -
Herramientas de gamificación para el aprendizaje de ciencias de la tierra
El porcentaje de abandono escolar en España es superior al de otros países de la Unión Europea, lo que hace necesario fomentar el rendimiento del alumnado y su motivación. En este contexto, la gamificación tiene un futuro ... -
Heterogeneous Fenton- and photo-Fenton-like catalytic degradation of emerging pollutants using Fe2O3/TiO2/pillared clays synthesized from aluminum industrial wastes
The presence of emerging pollutants (EPs) in water is a major environmental concern. This study evaluates for the first time the removal of three EPs, namely triclosan (TCS), 2,6-dichlorophenol (2,6-DCP), and bisphenol A ... -
High magnetic, transport, and optical uniaxial anisotropis generated by controlled directionally grown nano-sheets in Fe thin films
Fe films with thicknesses between 17 and 95 nm were grown with a nano-sheet morphology, which enabled their high uniaxial magnetic, transport, and optical in-plane anisotropies. The top edge of the nano-sheets was directly ... -
Highlighting complex long-term succession pathways in mixed forests of the Pacific Northwest: a Markov chain modelling approach
Forest succession is an ecological phenomenon that can span centuries. Although the concept of succession was originally formulated as a deterministic sequence of different plant communities by F. Clements more than a ... -
La huella litológica de los verracos vetones: análisis geoquímicos de las esculturas zoomorfas de la meseta nordoccidental
Arqueológicamente, el término verraco se aplica a las esculturas zoomorfas vettonas que representan toros o cerdos. El pueblo vetón ocupó un espacio impreciso entre las cuencas de los ríos Tajo y Duero en la Península ... -
Hybrid xerogels: study of the sol-gel process and local structure by vibrational spectroscopy
The properties of hybrid silica xerogels obtained by the sol-gel method are highly dependent on the precursor and the synthesis conditions. This study examines the influence of organic substituents of the precursor on the ... -
Hydrothermal liquefaction of biomass as one of the most promising alternatives for the synthesis of advanced liquid biofuels: a review
The use of biofuels offers advantages over existing fuels because they come from renewable sources, they are biodegradable, their storage and transport are safer, and their emissions into the atmosphere are lower. Biomass ... -
IAOx induces the SUR phenotype and differential signalling from IAA under different types of nitrogen nutrition in Medicago truncatula roots
Indole-3-acetaldoxime (IAOx) is a particularly relevant molecule as an intermediate in the pathway for tryptophan-dependent auxin biosynthesis. The role of IAOx in growth-signalling and root phenotype is poorly studied in ... -
Identification of a Ni-vacancy defect in Ni-Mn-Z (Z = Ga, Sn, In): an experimental and DFT positron-annihilation study
By means of experimental positron-annihilation-lifetime measurements and theoretical density functional theory (DFT) positron-lifetime calculations, vacancy-type defects in Ni50Mn50−xSnx (x = 25, 20, 15, 13, 10) and ... -
Impact of a thermoelectric subcooler heat exchanger on a carbon dioxide transcritical refrigeration facility
To improve the performance of vapour compression refrigeration cycles, the inclusion of a thermoelectric subcooler for low-medium power units has been the focus of recent studies due to its robustness, compactness and ... -
Impact of extraction conditions on the phenolic composition and antioxidant capacity of grape stem extracts
The use of grape stems for the extraction of bioactive compounds to be used in the pharmaceutical, food, and cosmetic industries is a promising objective. The aim of this work is to determine the influence of the different ... -
The importance of the urea cycle and its relationships to polyamine metabolism during ammonium stress in Medicago truncatula
The ornithine–urea cycle (urea cycle) makes a signifcant contribution to the metabolic responses of lower photosynthetic eukaryotes to episodes of high nitrogen availability. In this study, we compared the role of the plant ... -
Improved adhesion of cathodic arc PVD AlCrSiN coating on ion-implanted WC-Co substrates
Ion implantation has been shown to improve adhesion strength of AlCrSiN coatings due to a synergic enhancement on fracture toughness and load bearing capability of the substrate that can potentially increase the in-service ... -
Improved photocatalytic and antibacterial performance of Cr doped TiO2 nanoparticles
The effect of Cr and N doping in the adsorption capacity, photocatalytic properties and antibacterial response of TiO2 anatase nanoparticles is analyzed. The nanoparticles (N-TiO2, Cr-TiO2 and Cr/N-TiO2) were prepared by ... -
Improvement of the adsorption properties of an activated carbon coated by titanium dioxide for the removal of emerging contaminants
Three activated carbon coated titanium dioxide composites are evaluated as adsorbents for the removal of three pharmaceutical compounds: clofibric, gallic and salicylic acids from aqueous solutions. These composite materials ... -
In vitro evaluation of postbiotics produced from bacterial isolates obtained from rainbow trout and nile tilapia against the pathogens Yersinia ruckeri and Aeromonas salmonicida subsp. Salmonicida
The use of antibiotics in aquaculture leads to the proliferation of multidrug-resistant bacteria, and an urgent need for developing new alternatives to prevent and control disease has, thus, arisen. In this scenario, ... -
Incorporating climate effects in Larix gmelinii improves stem taper models in the Greater Khingan Mountains of Inner Mongolia, northeast China
Estimating timber volume and carbon stock in forests is fundamental for silviculture and for accurate estimation of national and global carbon budgets. Taper models are important tools for predicting diameter at any height ... -
Indole-3-acetaldoxime delays root iron-deficiency responses and modify auxin homeostasis in medicago truncatula
Iron (Fe) is an essential plant micronutrient, being a major limiting growth factor in calcareous soils. To increase Fe uptake, plants induce lateral roots growth, the expression of a Fe(III)-chelate reductase (FCR), a ...
