16 Years (2006–2021) of Surface Ozone Measurements in Córdoba (Southern Spain): Trends and the Impact of the COVID-19 Lockdown
(MDPI, 2022)Surface ozone concentrations (O3) during the period 2006–2021 are analysed at Córdoba city (southern Iberian Peninsula) in suburban and urban sampling sites. The aims are to present the levels and temporal variations, to ... -
A simple and accurate analytical model of the Stark profile and its application to plasma characterization
(Elsevier, 2018)Optical Emission Spectroscopy techniques are among the most employed to perform the characterization of laboratory plasmas. The analysis of the obtained data is based on the convolution of three different types of profiles: ... -
Accesibilidad a Internet: requisitos para la calidad en la docencia e investigación
(Universidad de Córdoba, Vicerrectorado de Innovación y Calidad Docente, 2005)A good Internet platform for teaching and research must be accessible, independently of the computer platform used, language and other peculiarities (personal or external). This work analyzes the current limitations of ... -
An experimental study of the dependence on the current intensity of the erosion of thoriated tungsten cathodes in plasma arcs
(IEEE, 2001)The erosion occurring in thoriated tungsten cathodes used in transferred plasma torches operating with current intensities ranging from 30 to 210 A has been experimentally investigated. The cathode erosion rate was determined ... -
An off-center endohedrally confined hydrogen molecule
(Royal Society of Chemistry, 2022)In this study, we address the problem of a C60 endohedrally confined hydrogen molecule through a configuration–interaction approach to electronic dynamics. Modeling the confinement by means of a combination of two Woods–Saxon ... -
Analysis of Alpha Activity Levels and Dependence on Meteorological Factors over a Complex Terrain in Northern Iberian Peninsula (2014–2018)
(MDPI, 2020)Alpha ambient concentrations in ground-level air were measured weekly in Bilbao (northern Spain) by collecting aerosols in filters between 2014 and 2018. Over this period, the alpha activity concentrations in the aerosol’s ... -
Aplicación del aprendizaje cooperativo a través de Tumblr para la adquisición de competencias
(UCOPress, 2020)El potencial de las redes sociales ha supuesto la aparición de herramientas alternativas para la adquisición de competencias a través de dinámicas de trabajo en grupo e interacción social. El objetivo de este proyecto es ... -
Atmospheric Pathways and Distance Range Analysis of Castanea Pollen Transport in Southern Spain
(MDPI, 2020)The sweet chestnut (Castanea sativa Mill.) is the only native species of this genus in Europe, where it faces various threats that are causing a severe decrease in populations, with the resulting loss of genetic diversity. ... -
BAO cosmology in non-spatially flat background geometry from BOSS+eBOSS and lessons for future surveys
(IOP Publishing, 2024)We study the impact of the assumption of a non-flat fiducial cosmology on the measurement, analysis and interpretation of BAO distance variables, along and across the line-of-sight. The assumption about cosmology enters ... -
Carbon Black as Conductive Additive and Structural Director of Porous Carbon Gels
(MDPI, 2020)This work investigates the impact of carbon black (CB) as a porogenic agent and conductive additive in the preparation of electrically conductive nanoporous carbon gels. For this, a series of materials were prepared by the ... -
Carbon Dioxide Decomposition by a Parallel-Plate Plasma Reactor: Experiments and 2-D Modelling
(MDPI, 2021)The applicability of high voltage electrical discharges for the decomposition of CO2 has been extensively demonstrated. In this study, a new AC parallel-plate plasma reactor is presented which was designed for this purpose. ... -
Characterization of an Air-Based Coaxial Dielectric Barrier Discharge Plasma Source for Biofilm Eradication
(Springer, 2018)Air-based atmospheric-pressure cold plasmas are a source of charged particles, excited species, radicals, and UV rays, known to induce degradation of biomaterials. In this work we characterize an air-based Dielectric Barrier ... -
Clinical and Biological Principles of Cold Atmospheric Plasma Application in Skin Cancer
(Springer, 2016)Plasma-based electrosurgical devices have long been employed for tissue coagulation, cutting, desiccation, and cauterizing. Despite their clinical benefits, these technologies involve tissue heating and their effects are ... -
Complementos pedagógicos para la enseñanza de la Teoría Cuántica en Física y su adecuación a la metodología del Espacio Europeo de Educación Superior

Confined orbitals in fullerenes and quantum dots calculated by analytic continuation method
(Springer, 2021)The Schrödinger equation with a Gaussian potential to model a confined system as a quantum dot or a hydrogen atom inside a fullerene is solved by using the analytic continuation method. The use of the Rodrigues formula ... -
Cosmology of an axion-like majoron
(IOP Publishing, 2022)We propose a singlet majoron model that defines an inverse seesaw mechanism in the ν sector. The majoron ϕ has a mass mϕ ≈ 0.5 eV and a coupling to the τ lepton similar to the one to neutrinos. In the early universe it is ... -
Design of multivariable PID control using iterative linear programming and decoupling
(MDPI, 2024)The design of multivariable process control systems is specially complicated when there are strong interactions between the different control loops, and even more with multiple time delays. This paper proposes an iterative ... -
Determinación de la constante de Hubble mediante observaciones del Universo Local
(Real Sociedad Española de Física, 2020-04)En este trabajo se ofrece el resultado de una determinación directa de la constante de Hubble H0 a partir de observaciones del Universo Local. Para ello hemos usado la técnica de la escalera cósmica de distancias siguiendo ... -
Effects of size on the spectrum and stability of a confined on-center Hydrogen atom
