La ocupación romana en la sierra norte de Sevilla: Castiblanco de los Arroyos
Nuestro artículo muestra cómo el poblamiento romano en una zona “marginal” ayuda a comprender el carácter de las rutas secundarias de comercio y distribución de bienes durante el Alto y Bajo Imperio en la Sierra Norte de Sevilla, en la orilla derecha del Baetis, dentro de los…

Isolation of plant-growth-promoting and metal-resistant cultivable bacteria from Arthrocnemum macrostachyum in the Odiel marshes with potential use in phytoremediation
Arthrocnemum macrostachyum is a halophyte naturally growing in southwest coasts of Spain that can tolerate and accumulate heavy metals. A total of 48 bacteria (30 endophytes and 18 from the rhizosphere) were isolated from A. macrostachyum growing in the Odiel River marshes, an…

Evolution of annual rainfall irregularity in the southwest of the Iberian Peninsula
The areas of the Iberian Peninsula with Mediterranean climate are characterised by rainfall irregularity. Standard statistical estimation methods provide a limited insight of all the dimensions of such irregularity. Based on different techniques to describe the inter-annual…

Maximum velocity during loaded countermovement jumps obtained with an accelerometer, linear encoder and force platform: A comparison of technologies
The maximum velocity (Vmax) reached during countermovement jumps (CMJ) has been considered a performance indicator to evaluate the vertical jump ability. The aim of this study was to compare Vmax during loaded CMJ (CMJload) using three different technologies to show a criterion…

VEGF and Neuronal Survival
Vascular endothelial growth factor (VEGF) is well known for its angiogenic activity, but recent evidence has revealed a neuroprotective action of this factor on injured or diseased neurons. In the present review, we summarize the most relevant findings that have contributed to…

The effects of teaching and assessment methods on academic performance: a study of an Operations Management course
Whether the use of more active teaching–learning methods has a positive impact on academic performance remains unanswered. This article seeks to contribute to the issue by conducting a study of an Operations Management course with almost 1000 students per year over three…

El pensamiento sistémico: del constructivismo a la complejidad
Se hace referencia a la importancia de desarrollar un modelo epistemológico derivado de la Teoría de Sistemas, reflexionándose sobre las dificultades existentes para ello, así como a las implicaciones educativas de dicho modelo, en la perspectiva de desarrollar una “teoría…
Numerical study of the inter-fibre failure under biaxial loads
The inter-fibre/matrix failure under transverse tension has already been the object of several micromechanical studies by the authors, for single fibre case or dilute packing. These studies have made it possible to understand the initiation and later progress of failure at the…

Voltage Mode Driver for Low Power Transmission of High Speed Serial AER Links
This paper presents a voltage-mode high speed driver to transmit serial AER data in scalable multi-chip AER systems. To take advantage of the asynchronous nature of AER (Address Event Representation) streams, this implementation allows an energy efficient burst-mode operation…

La influencia de la forma en las zapatas de medianera y de esquina
Se denomina cimentación a la parte de una estructura que transmite al terreno subyacente su propio peso, el de la superestructura y todas las sobrecargas. El cimiento es por tanto el enlace entre la superestructura y el terreno, y son por ello elementos básicos en el diseño y…
Tutte uniqueness of locally grid graphs
A graph is said to be locally grid if the structure around each of its vertices is a 3 × 3 grid. As a follow up of the research initiated in [4] and [3] we prove that most locally grid graphs are uniquely determined by their Tutte polynomial.
Effectiveness of Digital Mental Health Interventions for Children and Adolescents
Background/Objectives: Children’s mental health is an issue of growing global concern, with a significant impact on children’s emotional, social and cognitive development. In recent years, digital apps and platforms have emerged as innovative tools to address mental health…

Medialab Quito: um espaço participativo de cultura, arte, tecnologia e cidadania
O Medialab Quito é hoje um importante espaço equatoriano de apropriação cidadã com papel de propagar a participação, a cooperação e o compartilhamento de saberes e práticas, além do desenvolvimento de projetos inovadores ligados aos temas de comunicação, cultura, arte e…
Impact of the particles impingement on the electronic conductivity of Al doped ZnO films grown by reactive magnetron sputtering
Aluminium doped zinc oxide thin films (4 at.% Al) were deposited by reactive magnetron sputtering technique and characterized by X-ray diffraction (XRD), Rutherford backscattering spectroscopy (RBS), four point probe technique and optical spectrophotometry. High heterogeneities…

Learning Algorithms for Oscillatory Neural Networks as Associative Memory for Pattern Recognition
Alternative paradigms to the von Neumann computing scheme are currently arousing huge interest. Oscillatory neural networks (ONNs) using emerging phase-change materials like VO2 constitute an energy-efficient, massively parallel, brain-inspired, in-memory computing approach. The…
