System Stability of a Small Island's Network with Different Levels of Wind Power Penetration
2018
The reduction of the inertial response of the generation system has been one of the main obstacles to the penetration of high sharing of renewable energy sources in islanded systems. This issue can be solved thanks to innovative control that makes wind turbines able to provide the so-named synthetic inertia. The paper investigates some scenarios with different levels of wind power penetration in a small island whose grid is not supplied by the main grid, by the use of the software NEPLAN 360, simulating the wind power plants accordingly to the standard IEC 61400-27. The aim of the paper is to assess the maximum level of penetration in the island of wind generation, with traditional control …
Effect of nut consumption on oxidative stress and the endothelial function in metabolic syndrome
2010
Effect of nut consumption on oxidative stress and the endothelial function in metabolic syndrome BACKGROUND & AIMS: Oxidative stress has a key role in atherosclerosis, cancer and other chronic diseases. Some bioactive compounds in nuts have been implicated in antioxidant activities. OBJECTIVE: We assessed how nut consumption affected several markers of oxidation and endothelial function (EF) in metabolic syndrome (MetS) patients. PATIENTS AND METHODS: A randomized, controlled, parallel feeding trial was conducted on 50 MetS adults who were recommended a healthy diet supplemented or not with 30 g of mixed nuts (Nut and Control groups, respectively) every day for 12 weeks. The plasma anti…
A Cross-Country Examination on the Fear of COVID-19 and the Sense of Loneliness during the First Wave of COVID-19 Outbreak
2021
The aim of the current study is to examine gender, age. and cross-country differences in fear of COVID-19 and sense of loneliness during the lockdown, by comparing people from those countries with a high rate of infections and deaths (e.g., Spain and Italy) and from countries with a mild spread of infection (e.g., Croatia, Serbia, Slovakia, Slovenia, and Bosnia and Herzegovina). A total of 3876 participants (63% female) completed an online survey on “Everyday life practices in COVID-19 time” in April 2020, including measures of fear of COVID-19 and loneliness. Males and females of all age groups in countries suffering from the powerful impact of the COVID-19 pandemic reported greater fear o…
Comparison of European ICU patients in 2012 (ICON) versus 2002 (SOAP)
2018
Purpose: To evaluate differences in the characteristics and outcomes of intensive care unit (ICU) patients over time. Methods: We reviewed all epidemiological data, including comorbidities, types and severity of organ failure, interventions, lengths of stay and outcome, for patients from the Sepsis Occurrence in Acutely ill Patients (SOAP) study, an observational study conducted in European intensive care units in 2002, and the Intensive Care Over Nations (ICON) audit, a survey of intensive care unit patients conducted in 2012. Results: We compared the 3147 patients from the SOAP study with the 4852 patients from the ICON audit admitted to intensive care units in the same countries as those…
Demonstration of remote optical measurement configuration that correlates to glucose concentration in blood
2010
An optical approach allowing the extraction and the separation of remote vibration sources has recently been proposed. The approach has also been applied for medical related applications as blood pressure and heart beats monitoring. In this paper we demonstrate its capability to monitor glucose concentration in blood stream. The technique is based on the tracking of temporal changes of reflected secondary speckle produced in human skin (wrist) when being illuminated by a laser beam. A temporal change in skin’s vibration profile generated due to blood pulsation is analyzed for estimating the glucose concentration. Experimental tests that were carried out in order to verify the proposed appro…
Interacción genético-ambiental en la modulación de adipocitoquinas y marcadores de inflamación en su asociación con obesidad y otros factores de ries…
2011
La obesidad es una enfermedad metabólica resultado del desequilibrio entre el consumo y el gasto energético, con el consecuente aumento de la cantidad de grasa corporal. Este aumento de grasa corporal produce un desequilibrio en la secreción de adipocitoquinas y marcadores de inflamación relacionado con diversas complicaciones clínicas asociadas con la obesidad y otros factores de riesgo cardiovascular. Las investigaciones de las últimas décadas han permitido un notable aumento en la compresión de los mecanismos moleculares que regulan la homeostasis de la energía, poniendo de manifiesto la importancia de los factores ambientales en la modulación de las reservas energéticas. Además, la vari…
Purity rules in Pentecostal Uganda. Towards an analysis of relational rulework
2022
Rules concerning romantic relationships and sex—what we term ‘purity rules’—are central to Pentecostalism in Uganda. In public church arenas, the born-again variant of the rules laid down during Uganda’s ‘ABC’ response to HIV/AIDS — ‘abstain till marriage and be faithful once you marry’—are presented as clear and non-negotiable. Yet in church members’ lives, and in their conversations with each other or in small church groups, space is often created for interpretation and deliberation about the officially strict rules. In this article, we use ethnographic material from fieldwork in urban Pentecostal churches in Uganda to describe how rules work on people, and people work on rules. We descr…
On Dealing with Uncertainties from Kriging Models in Offline Data-Driven Evolutionary Multiobjective Optimization
2019
Many works on surrogate-assisted evolutionary multiobjective optimization have been devoted to problems where function evaluations are time-consuming (e.g., based on simulations). In many real-life optimization problems, mathematical or simulation models are not always available and, instead, we only have data from experiments, measurements or sensors. In such cases, optimization is to be performed on surrogate models built on the data available. The main challenge there is to fit an accurate surrogate model and to obtain meaningful solutions. We apply Kriging as a surrogate model and utilize corresponding uncertainty information in different ways during the optimization process. We discuss…
Current status of the salutogenesis in Spain. Fifteen years of research
2014
Tras siglos de visión patogénica del cuidado de la salud, en los años 70 el sociólogo y médico Aaron Antonovsky introdujo un modelo de salud que con los años se ha convertido en un concepto establecido en la salud pública y la promoción de la salud, la ‘Salutogénesis’, que propone entender la salud como un continuo entre bienestar y enfermedad en lugar de una visión en que salud y enfermedad se excluyen mutuamente, coincidiendo con el actual enfoque de la Organización Mundial de la Salud. Este trabajo tiene como objetivo principal realizar una revisión y análisis de su estudio y utilización en España, donde va introduciéndose de forma progresiva, con más de 10 artículos publicados, una conf…
Análisis comparativo de las funciones de predicción del riesgo cardiovascular SCORE y Framingham y sus versiones calibradas, SCORE calibrada y REGIDO…
2009
Introducción: Las recomendaciones del ATPIII y las SSCC europeas en prevención primaria cardiovascular aconsejan para la estimación del riesgo individual las funciones de Framingham y SCORE respectivamente. Ambas disponen de versiones calibradas para la población española. Todas, excepto Framingham(ATPIII), han sido derivadas para aplicarlas en un rango de edad limitado. Por otra parte, ninguna de estas funciones predice el riesgo cardiovascular total, ya que SCORE y SCORE calibrada sólo estima el riesgo de muerte y Framingham(ATPIII) y REGICOR el riesgo coronario. Sin embargo todas las medidas preventivas van dirigidas a la prevención de la enfermedad cardiovascular globalmente y las funci…
