An exploratory study to investigate emotion elicited by immersive ambiances

2011

Food behaviour is modulated by the eating situation and environment. In a previous study, we investigated drink choices according to the ambiance by developing an immersive approach based on the concept of “having a drink in a bar”. Two bars (Modern vs. Traditional ambiance) were settled with a few piece of furniture (counter, tables and bar stools) made in raw wood for the Traditional bar and in blue retro-lighted translucent plastic for the Modern bar. A video-clip was projected on one wall: Red moving shapes associated to a “far west” music in the Traditional bar, and Blue moving bubbles associated to an “electro” music in the Modern bar. In each bar, 100 participants were asked which be…

Investigating the Heartbeat-evoked cortical responses through parametric Time-Varying Information Measures

2022

Recent studies showed that the information coming from the heart is constantly processed by the brain. One index to study this process is the heartbeat-evoked potential (HEP), represented by an event-related potential component related to the cortical processing of the heartbeat. In this study we propose an approach to investigate the heartbeat-evoked EEG responses, based on quantifying the changes induced by the heartbeat on the predictability of the brain dynamics. The regularity of EEG signals is assessed through the Information Storage (IS) computed with a time-varying approach able to derive the temporal profile of the measure for each time point. Results show a modulation in the regul…

Estudio volumétrico de la cresta ósea infracigomática mediante tomografía computarizada de haz cónico

2023

Introducción. El estudio anatómico en tres dimensiones de la cresta infracigomática bajo un protocolo de estudio común, previo a la colocación de dispositivos de anclaje temporal, proporciona al clínico una herramienta de pronóstico clave en la seguridad y estabilidad del tratamiento. Objetivos. El propósito de la presente tesis doctoral fue evaluar de forma transversal la cresta ósea infracigomática (IZC) mediante Tomografías Computarizadas de Haz Cónico (TCHC) en primeros y segundos molares superiores, para el estudio sistematizado y enfocado a la colocación de dispositivos de anclaje temporal en ortodoncia. Los objetivos fueron: determinar la altura total de la cresta infracigomática en …

One pot light assisted green synthesis, storage and antimicrobial activity of dextran stabilized silver nanoparticles.

2014

Background Green synthesis of nanomaterials finds the edge over chemical methods due to its environmental compatibility. Herein, we report green synthesis of silver nanoparticles (Ag NPs) mediated with dextran. Dextran was used as a stabilizer and capping agent to synthesize Ag NPs using silver nitrate (AgNO3) under diffused sunlight conditions. Results UV–vis spectra of as synthesized Ag nanoparticles showed characteristic surface plasmon band in the range from ~405-452 nm. Scanning electron microscopy (SEM) and atomic force microscopy (AFM) studies showed spherical Ag NPs in the size regime of ~50-70 nm. Face centered cubic lattice of Ag NPs was confirmed by powder X-ray diffraction (PXRD…

Cambio climático y sustentabilidad económica y social: implicaciones sobre el bienestar social

2008

This article puts forward an explanation of climate change within the context of global change. Climate change can be seen as the spearhead; as a manifestation of the increasing unsustainability of planet Earth. We consider some of the effects of this change, examining its uneven impact on developed and under-developed countries. We then put forward various proposals of how to deal with climate change, highlighting Socolow’s theory in particular. Lastly, we move on to the debate raised by climate change, its impact and possible strategic steps to remedy the situation within the context of environmental sustainability. This will probably lead to a new economic, social and environmental parad…

First operational experience of HIE-ISOLDE

2016

The High Intensity and Energy ISOLDE project (HIE-ISOLDE)* is a major upgrade of the ISOLDE facility at CERN. The energy range of the post-accelerator will be extended from 2.85 MeV/u to 9.3 MeV/u for beams with A/q = 4.5 (and to 14.3 MeV/u for A/q = 2.5) once all the cryomodules of the superconducting accelerator are in place. The project has been divided into different phases, the first of which (phase 1a) finished in October 2015 after the hardware and beam commissioning were completed**. The physics campaign followed with the delivery of both radioactive and stable beams to two different experimental stations. The characteristics of the beams (energies, intensities, time structure and b…
