El Empleo con Apoyo en España: Análisis de Variables que Determinan la Obtención y Mejora de Resultados en el Desarrollo de Servicios

[From Prólogo] El presente documento es la publicación de la tesis doctoral desarrollada por Borja Jordán de Urríes Vega en la cual he participado como director de la investigación, y a la que el tribunal otorgó la calificación de Sobresaliente Cum Laude. Si cualquier tesis implica un proceso de aprendizaje de habilidades investigadoras, en este caso no ha ocurrido de otra manera, y tanto el hoy compañero y Doctor Borja como yo mismo, nos hemos visto inmersos en un proceso que se desarrolló durante más de cuatro años, en el cual hemos tratado de profundizar en un tema de gran interés y relevancia para el mundo de la discapacidad

El método etológico observacional en el medio natural: aplicación al análisis de la actividad y pautas de comportamiento en lagartos de Tenerife (Islas Canarias)

Se presentan los resultados preliminares de la aplicación del método etológico observacional al estudio de la actividad en lagartos de Tenerife en dos zonas de la isla con características ecológicas diferentes (Malpaís de Güimar y en la periferia del Parque Nacional del Teide) y en dos tramos horarios (mañana y mediodía). Durante transectos elegidos al azar, se contabilizó el número de ejemplares activos de cada sexo y categoría, así como el tipo de pauta de comportamiento que realizaban. En ambas zonas fue siempre mayor el número de ejemplares machos activos que el de hembras o juveniles. El número total de animales activos por unidad de área y tiempo estuvo relacionada inversamente con la temperatura ambiental en la zona del P.N. del Teide, mientras que tuvo un máximo a temperaturas intermedias entre los valores máximos en el Malpaís de Güimar. En esta última zona el número de ejemplares observados fue mayor al mediodía que en la mañana, mientras que ocurrió lo contrario en el P.N. del Teide. Estos resultados preliminares apoyan lo encontrado en otras especies respecto al mayor nivel de actividad de los machos. Además, sugieren un patrón diferencial de actividad en relación a la temperatura ambiental en las dos zonas estudiadas.We present preliminary results on the application of the observational ethological method to the study of activity of lizards from Tenerife in two habitats of the island with different ecological characteristics: Malpaís de Güimar (SE of the island) and the periphery of Teide National Park (centre of the island), and in two daily times. We counted the number of animals of each sex and category while walking in transects with hazardously chosen directions. The behaviour pattern performed by each observed animal was also scored. The results show that there were always more active males than females or juveniles in both zones. The number of total active animals per unit area and time was inversely related to the environmental temperature in Teide National Park. In Malpaís de Güimar the higher number of animals was recorded in intermediate temperatures between maximum and minimum ones. The number of observed animals was greater at midday than in the morning in Malpaís de Güimar, but the contrary occurred at Teide N.P. The results support the finding in other species of a higher activity level in males and also suggest a differential activity pattern in relation to environmental temperature in both zones studied

Closerange Photogrametry. Previous Works to the Data Collection

La Fotogrametría es la técnica cuyo fin es estudiar y definir con precisión la forma, dimensiones y posición en el espacio de un objeto cualquiera, utilizando esencialmente medidas hechas sobre una o varias fotografías de ese objeto. Para la correcta toma de las fotografías es necesario conocer el funcionamiento interno de las cámaras fotográficas. En este artículo se desarrolla el cálculo de la posición desde la cual tomar una fotografía para obtener una resolución adecuada, así como la distancia entre una imagen y la siguiente para que el solape sea correcto. La relación existente entre la distancia focal, f, de una cámara de fotos, y la distancia entre la cámara y el objeto a fotografiar, H, cumple con la siguiente característica: es igual a la relación entre el ancho del tamaño del sensor, w, y el ancho real del objeto fotografiado, W. Partiendo de esta relación de proporcionalidad se desarrollan una serie de cálculos que, por seguro, se deben tener en cuenta al planificar un trabajo de fotogrametría terrestre

Analysis of the Fracture of Reinforced Concrete Flat Elements Subjected to Explosions. Experimental Procedure and Numerical Validation

Many of the material models most frequently used for the numerical simulation of the behavior of concrete when subjected to high strain rates have been originally developed for the simulation of ballistic impact. Therefore, they are plasticity-based models in which the compressive behavior is modeled in a complex way, while their tensile failure criterion is of a rather simpler nature. As concrete elements usually fail in tensión when subjected to blast loading, available concrete material models for high strain rates may not represent accurately their real behavior. In this research work an experimental program of reinforced concrete fíat elements subjected to blast load is presented. Altogether four detonation tests are conducted, in which 12 slabs of two different concrete types are subjected to the same blast load. The results of the experimental program are then used for the development and adjustment of numerical tools needed in the modeling of concrete elements subjected to blast

From Science to Policy and Society: Enhancing the Effectiveness of Communication

Abstract Dissemination is now acknowledged as an important component of the research process, in particular for European Union (EU) funded research projects. This article builds on the authors' experience during the EU project DEVOTES (DEVelopment Of innovative Tools for understanding marine biodiversity and assessing good Environmental Status) and aims to assist other scientists to develop a successful dissemination strategy to communicate project achievements. We provide a critical review of the different tools used for outreach to our target audiences, from the academia to the policy makers, and the general public, and try to assess their impact. An effective dissemination strategy and plan should have a clear objective, be designed before the start of the project, identify the target groups and define the methods or tools to be used according to target groups and objectives. The DEVOTES dissemination strategy included two complementary approaches of communication with stakeholders: (i) traditional (e.g., peer reviewed publications, stakeholders workshops, and participation in scientific conferences), and (ii) new (e.g., social networks, smartphone applications) media tools. For each dissemination approach, we defined production targets (e.g., number of articles to be published, individual visitors on the website, etc.) to be achieved by the end of the project, and impact measurements (e.g., citation indices for peer reviewed articles) to monitor the successful implementation of DEVOTES Dissemination. This allowed us to identify which tools had been more (e.g., website) or less useful and relevant (e.g., Facebook) during the project. We conclude that impact measurements cannot be easily identified for all dissemination actions. However, for those that were possible, the DEVOTES dissemination targets were successfully achieved. Overall, the use of the tools and activities outlined in this article, combined with the constant evaluation of the dissemination goals throughout the project duration and the assessment of the effectiveness of the different tools, is essential for the achievement of an effective and timely communication of research results

Post-combustion calcium looping process with a high stable sorbent activity by recarbonation

[EN] This paper presents a novel sorbent regeneration technique for post-combustion calcium looping CO2 capture systems. The advantage of this technique is that it can drastically reduce the consumption of limestone in the plant without affecting its efficiency and without the need for additional reagents. The method is based on the re-carbonation of carbonated particles circulating from the carbonator using pure CO2 obtained from the gas stream generated in the calciner. The aim is to maintain the CO2 carrying capacity of the sorbent close to optimum values for CaL post-combustion systems (around 0.2). This is achieved by placing a small regeneration reactor between the carbonator and the calciner. This reactor increases slightly the conversion of CaO to carbonate so that it exceeds the so-called maximum CO2 carrying capacity of the sorbent. This increase compensates for the loss of CO2 carrying capacity that the solids undergo in the next calcination-carbonation cycle. Two series of experiments carried out in a thermogravimetric analyzer over 100 cycles of carbonation-recarbonation-calcination show that the inclusion of this recarbonation step is responsible for an increase in the residual CO2 carrying capacity from 0.07 to 0.16. A conceptual design of the resulting capture system shows that a limestone make-up flow designed specifically for a CO2 capture system can approach zero, when the solid sorbents purged from the CaL system are re-used to desulfurize the flue gas in the existing power plant.We thank the European Commission for the financial support received through the “CaOling” Project, funded under the 7th Framework Programme.Peer reviewe

Tsunami vs. storm surge deposits: a review of the sedimentological and geomorphological records of extreme wave events (EWE) during the Holocene in the Gulf of Cadiz, Spain

The Gulf of Cadiz region of Spain has undergone many studies examining Holocene tsunami and storm deposists. Some of the studies aimed at determining recurrence intervals of events interpreted of tsunamigenic origin. A review of geomorphologic, sedimentary and paleontological features of these deposits suggests that only a few of them can be accurately ascribed to tsunami events; instead, most of them lack conclusive evidence of a tsunamigenci genesis and should be referred to as generated by extreme wave events (EWE

Numerical analysis of seepage–deformation in unsaturated soils

A coupled elastic–plastic finite element analysis based on simplified consolidation theory for unsaturated soils is used to investigate the coupling processes of water infiltration and deformation. By introducing a reduced suction and an elastic–plastic constitutive equation for the soil skeleton, the simplified consolidation theory for unsaturated soils is incorporated into an in-house finite element code. Using the proposed numerical method, the generation of pore water pressure and development of deformation can be simulated under evaporation or rainfall infiltration conditions. Through a parametric study and comparison with the test results, the proposed method is found to describe well the characteristics during water evaporation/infiltration into unsaturated soils. Finally, an unsaturated soil slope with water infiltration is analyzed in detail to investigate the development of the displacement and generation of pore water pressure

Alberta Stroke Program Early CT Score applied to CT angiography source images is a strong predictor of futile recanalization in acute ischemic stroke

The final publication is available at Springer via http://dx.doi.org/10.1007/s00234-016-1652-7Introduction Reliable predictors of poor clinical outcome despite successful revascularization might help select patients with acute ischemic stroke for thrombectomy. We sought to determine whether baseline Alberta Stroke Program Early CT Score (ASPECTS) applied to CT angiography source images (CTA-SI) is useful in predicting futile recanalization. Methods Data are from the FUN-TPA study registry (ClinicalTrials.gov; NCT02164357) including patients with acute ischemic stroke due to proximal arterial occlusion in anterior circulation, undergoing reperfusion therapies. Baseline non-contrast CT and CTA-SI-ASPECTS, timelapse to image acquisition, occurrence, and timing of recanalization were recorded. Outcome measures were NIHSS at 24 h, symptomatic intracranial hemorrhage, modified Rankin scale score, and mortality at 90 days. Futile recanalization was defined when successful recanalization was associated with poor functional outcome (death or disability). Results Included were 110 patients, baseline NIHSS 17 (IQR 12; 20), treated with intravenous thrombolysis (IVT; 45 %), primary mechanical thrombectomy (MT; 16 %), or combined IVT+MT (39 %). Recanalization rate was 71 %, median delay of 287 min (225; 357). Recanalization was futile in 28 % of cases. In an adjusted model, baseline CTA-SI-ASPECTS was inversely related to the odds of futile recanalization (OR 0.5; 95 % CI 0.3–0.7), whereas NCCT-ASPECTS was not (OR 0.8; 95 % CI 0.5–1.2). A score ≤5 in CTA-SIASPECTS was the best cut-off to predict futile recanalization (sensitivity 35 %; specificity 97 %; positive predictive value 86 %; negative predictive value 77 %). Conclusions CTA-SI-ASPECTS strongly predicts futile recanalization and could be a valuable tool for treatment decisions regarding the indication of revascularization therapie
