Application of anti-transpirants temporarily alleviates the inhibition of symbiotic nitrogen fixation in drought-stressed pea plants
(Elsevier, 2019)
info:eu-repo/semantics/article,
Stomatal closure is one of the first plant responses under a water deficit situation. This leads to a decline in transpiration but also in the plant photosynthetic activity. Legume plants grown under symbiosis with rhizobium ...
Control of a photovoltaic array interfacing current-mode-controlled boost converter based on virtual impedance emulation
(IEEE, 2019)
info:eu-repo/semantics/article,
Due to the nonlinear characteristics of a photovoltaic (PV) array, its regulation is highly dependent on the operating point. Focusing on a dc-dc boost converter, this paper first shows how the PV voltage and inductor ...
An academic analysis with recommendations for water management and planning at the basin scale: a review of water planning in the Segura River Basin
(Elsevier, 2019)
info:eu-repo/semantics/article,
Water resources management is particularly challenging in water-scarce basins, where low water availability is combined with a potential water demand exceeding the supply capacity of the natural system. This is the case ...
A corpus-driven analysis of certainty stance adverbs: obviously, really and actually in spoken native and learner English
(Elsevier, 2019)
info:eu-repo/semantics/article,
This paper examines the most frequent certainty adverbs in the extended LOCNEC (Aguadoet al. 2012) and their frequency and use in three datasets of the LINDSEI (Chinese, Germanand Spanish LINDSEI components). Our analysis ...
Biodiesel production from heterogeneous catalysts based K2CO3 supported on extruded Γ-Al2O3
(Elsevier, 2019)
info:eu-repo/semantics/article,
Catalytic biodiesel production from sunflower oil and ethanol using K2CO3/γ-Al2O3 in different configurations has been studied. To prepare the catalysts, boehmite was extruded with the aid of a binder and different percentages ...
Modeling ground-shielded integrated inductors incorporating frequency-dependent effects and considering multiple resonances
(IEEE, 2019)
Artículo / Artikulua,
A model for integrated spiral inductors which incorporates the physically expected frequency-dependent effects modifying the device's impedance is proposed. Moreover, it is demonstrated that the effect of resonances occurring ...
Componentes y dimensiones que caracterizan una buena praxis en Educación Infantil (0-3 años)
(Universidad de Murcia, 2019)
info:eu-repo/semantics/article,
Para mejorar la calidad educativa, es fundamental investigar y visibilizar buenas prácticas
docentes. Desde hace varios años y en esta línea, las autoras intervienen en proyectos de
innovación e investigación centrados ...
Holographic acoustic tweezers
(National Academy of Sciences, 2019)
info:eu-repo/semantics/article,
Acoustic tweezers use sound radiation forces to manipulate matter without contact. They provide unique characteristics compared with the more established optical tweezers, such as higher trapping forces per unit input power ...
Postnatal development of NPY and somatostatin-28 peptidergic populations in the human angular bundle
(Frontiers Media, 2019)
info:eu-repo/semantics/article,
The angular bundle is a white matter fiber fascicle, which runs longitudinally along the parahippocampal gyrus. It is best known for carrying fibers from the entorhinal cortex (EC) to the hippocampus through the perforant ...
On the stability of advanced power electronic converters: the Generalized Bode Criterion
(IEEE, 2019)
info:eu-repo/semantics/article,
A key factor in the design of power electronic converters is the development of control systems and, in particular, the determination of their stability. Due to ease of application, the Bode criteria are currently the most ...
