On the Selection of Non-Invasive Methods Based on Speech Analysis Oriented to Automatic Alzheimer Disease Diagnosis

The work presented here is part of a larger study to identify novel technologies and biomarkers for early Alzheimer disease (AD) detection and it focuses on evaluating the suitability of a new approach for early AD diagnosis by non-invasive methods. The purpose is to examine in a pilot study the potential of applying intelligent algorithms to speech features obtained from suspected patients in order to contribute to the improvement of diagnosis of AD and its degree of severity. In this sense, Artificial Neural Networks (ANN) have been used for the automatic classification of the two classes (AD and control subjects). Two human issues have been analyzed for feature selection: Spontaneous Speech and Emotional Response. Not only linear features but also non-linear ones, such as Fractal Dimension, have been explored. The approach is non invasive, low cost and without any side effects. Obtained experimental results were very satisfactory and promising for early diagnosis and classification of AD patients.

Enhanced Operation of Electricity Distribution Grids Through Smart Metering PLC Network Monitoring, Analysis and Grid Conditioning

Low Voltage (LV) electricity distribution grid operations can be improved through a combination of new smart metering systems' capabilities based on real time Power Line Communications (PLC) and LV grid topology mapping. This paper presents two novel contributions. The first one is a new methodology developed for smart metering PLC network monitoring and analysis. It can be used to obtain relevant information from the grid, thus adding value to existing smart metering deployments and facilitating utility operational activities. A second contribution describes grid conditioning used to obtain LV feeder and phase identification of all connected smart electric meters. Real time availability of such information may help utilities with grid planning, fault location and a more accurate point of supply management.

Fiber Bragg Gratings, IT Techniques and Strain Gauge Validation for Strain Calculation on Aged Metal Specimens

This paper studies the feasibility of calculating strains in aged F114 steel specimens with Fiber Bragg Grating (FBG) sensors and infrared thermography (IT) techniques. Two specimens have been conditioned under extreme temperature and relative humidity conditions making comparative tests of stress before and after aging using different adhesives. Moreover, a comparison has been made with IT tecniques and conventional methods for calculating stresses in F114 steel. Implementation of Structural Health Monitoring techniques on real aircraft during their life cycle requires a study of the behaviour of FBG sensors and their wiring under real conditions, before using them for a long time. To simulate aging, specimens were stored in a climate chamber at 70 degrees C and 90% RH for 60 days. This study is framed within the Structural Health Monitoring (SHM) and Non Destructuve Evaluation (NDE) research lines, integrated into the avionics area maintained by the Aeronautical Technologies Centre (CTA) and the University of the Basque Country (UPV/EHU).

Temperature-and pH-Sensitive Nanohydrogels of Poly(N-Isopropylacrylamide) for Food Packaging Applications: Modelling the Swelling-Collapse Behaviour

Temperature-sensitive poly(N-isopropylacrylamide) (PNIPA) nanohydrogels were synthesized by nanoemulsion polymerization in water-in-oil systems. Several cross-linking degrees and the incorporation of acrylic acid as comonomer at different concentrations were tested to produce nanohydrogels with a wide range of properties. The physicochemical properties of PNIPA nanohydrogels, and their relationship with the swelling-collapse behaviour, were studied to evaluate the suitability of PNIPA nanoparticles as smart delivery systems (for active packaging). The swelling-collapse transition was analyzed by the change in the optical properties of PNIPA nanohydrogels using ultraviolet-visible spectroscopy. The thermodynamic parameters associated with the nanohydrogels collapse were calculated using a mathematical approach based on the van't Hoff analysis, assuming a two-state equilibrium (swollen to collapsed). A mathematical model is proposed to predict both the thermally induced collapse, and the collapse induced by the simultaneous action of two factors (temperature and pH, or temperature and organic solvent concentration). Finally, van't Hoff analysis was compared with differential scanning calorimetry. The results obtained allow us to solve the problem of determining the molecular weight of the structural repeating unit in cross-linked NIPA polymers, which, as we show, can be estimated from the ratio of the molar heat capacity (obtained from the van't Hoff analysis) to the specific heat capacity (obtained from calorimetric measurements).

Disminución de la Ansiedad Estado previa al Cateterismo Cardiaco programado tras una intervención de enfermería

Los pacientes sometidos a cateterismo cardíaco (CC) experimentan niveles significativos de ansiedad relacionados con el procedimiento y puede ser percibido como una amenaza. Es fundamental por ello desarrollar estrategias de educación que se centren en las necesidades psicológicas y fisiológicas, manteniendo una información ordenada y clara, con el propósito de manejar y prevenir las complicaciones que se pueden presentar. El objetivo de este estudio es conocer si disminuye la ansiedad del paciente por medio de una intervención educativa enfermera, previa a la realización por primera vez del CC programado e Identificar el nivel de conocimientos sobre la prueba, el grado de satisfacción y confianza tras los cuidados enfermeros. Basado tanto en la información verbal, escrita y visualizada por medio de CD, como por la realización de técnicas cognitivas-conductuales. Apoyado por musicoterapia durante el periodo de espera previo al inicio del CC. Metodología: Sera un estudio experimental de ensayo clínico aleatorio, desarrollado en el Hospital Universitario Cruces (País Vasco-España), donde se crearan dos grupos: grupo control (pacientes antes de aplicar la intervención educativa, es decir, con la atención habitual) y grupo experimental (pacientes a los que se les aplica la intervención educativa).Formaran parte los primeros 225 pacientes mayores de 18 años que cumplan los requisitos de inclusión. Considero que es justificable la realización de este estudio, puesto que permitirá comprobar la eficacia de una intervención educativa de enfermería contribuyendo así a la disminución de la ansiedad y por consiguiente se podría protocolizar la intervención previa al procedimiento.

[ES] El tramo de muralla se compone de un lienzo recto de unos 40 metros de longitud y entre 6 y 12 metros de altura visible (según los tramos). En el centro de este tramo se encuentra una puerta monumental (denominada Puerta del Camino) a la que se accede por un puente. Este tramo recto se continúa por un cubo cilíndrico de unos 10 metros de radio. Continuando por el otro lado del Cubo la muralla se ha perdido pero se ha realizado una excavación que se extiende otros 30 metros en la que se han encontrado restos de varios sistemas defensivos.
