Cerebros en obras y en llamas "De autillo a búho nival". Altas Capacidades Intelectuales en defensa de la aceleración

344 páginas«Un país que no mima, cuida, protege y prepara adecuadamente su mejor activo, “para el mundo que viene”, está condenado a una gran dependencia externa, al no progreso social y al estancamiento, en la competitiva Era de la Globalización…». ¿Qué está ocurriendo con las personas de Altas Capacidades Intelectuales (AACC), en nuestros entornos más inmediatos? Proporcionar al lector la posibilidad de conocer algunas «experiencias positivas y gratas» del autor, vividas en el trato con las «personas de AACC», –a lo largo de décadas– reflejado en un recorrido «desde la infancia hasta el mundo del trabajo» con preguntas y testimonios variados…, nos impulsa a animar y creer seriamente, que «otra realidad diferente a la actual» en el panorama estatal de las AACC, es necesaria ¡ya!; ya que el estado de la cuestión a nivel del Estado, en lo relativo a la «atención a las AACC», –que posiblemente, Vd. ya conoce–, es más que triste y altamente deficitario… Actuar sin mayor dilación para que los suaves vientos de cambio, que se están produciendo en educación impulsen adecuadamente las AACC y su «adecuada visibilidad y atención», es una necesidad que no debiera demorarse más en el tiempo

Análisis de Ruido en Reactores PWR

Esta tesis se ha llevado a cabo persiguiendo dos objetivos principales: uno de ellos es el desarrollo y la aplicación de modelos para el mantenimiento predictivo de sensores en centrales nucleares, y el otro es profundizar en el entendimiento de los fenómenos que tienen influencia en el ruido de la señal de los detectores de neutrones de los reactores de agua a presión con ayuda de herramientas de simulación 3D. Para el desarrollo de los trabajos se ha contado con medidas de ruido de reactores PWR actualmente en operación registradas en el curso de la tesis. El análisis de estas medidas ha permitido desarrollar los modelos de los sensores a partir de sus señales reales y comparar lo obtenido en las simulaciones con la realidad. El estudio de los sensores y la elaboración de los modelos se han llevado a cabo mediante la aplicación de técnicas autorregresivas a las señales tomadas en planta. Para la reproducción de los fenómenos que tienen lugar en el núcleo del reactor y que pueden influir en el ruido neutrónico se ha contado con códigos neutrónicos ampliamente utilizados en la industria y con modelos actualizados y validados de las plantas. ABSTRACT There are two goals in this thesis. The first one is the development of models and its application for predictive maintenance of sensors in nuclear power plants. The second one is to improve the understanding of the phenomena that influence the neutron noise in pressurized water reactors by using 3D simulators. Real plant measurements recorded during this thesis have been used to achieve such goals. The information provided by the data led the development of the models and the comparison of the results provided by the computational simulations. Sensor models were obtained by applying autorregresive techniques to the signals recorded in the plant. Wide known codes in the nuclear industry as well as updated and validated models have been used for the reproduction of the phenomena that take place in the core an may influence the neutron noise

Characterization and Use of Char Produced from Pyrolysis of Post-Consumer Mixed Plastic Waste

In this work, the pyrolysis of post-consumer mixed plastic waste (polypropylene (PP), polystyrene (PS) and polyethylene film (PE)) is carried out. The solid product of the pyrolysis is characterized and tested for its use as adsorbent of lead present in aqueous media. The pyrolysis temperature has a great influence on the solid product yield, decreasing when the temperature increases. The highest yield to solid product obtained is from the pyrolysis of film at lower temperature (450 ◦C), reaching almost 14%. The results of product solid characterization reveal that the carbon, hydrogen and nitrogen content decreases with increasing pyrolysis temperature. Furthermore, both the ash and the volatile content are related to the pyrolysis temperature. The ash content is higher when the pyrolysis temperature is higher, while when the temperature increases, a solid product with lower volatile content is obtained. In respect to specific surface area, a higher pyrolysis temperature improves the properties of the solid product as an adsorbent. The adsorption capacity increases as the pyrolysis temperature increases, with the highest value of 7.91 mg/g for the solid obtained in the pyrolysis at 550 ◦C. In addition, adsorption capacity increases as the initial concentration of lead rises, reaching a maximum value close to 26 mg/g for an initial concentration of 40 mg/L. The Sips model is the one that best reproduces the experimental results of the adsorption process equilibrium study.PID2019-108826RB-I00/SRA (State Research Agency)/10.13039/50110001103

Six Collective Challenges for Sustainability of Almería Greenhouse Horticulture

Globally, current food consumption and trade are placing unprecedented demand on agricultural systems and increasing pressure on natural resources, requiring tradeoffs between food security and environmental impacts especially given the tension between market-driven agriculture and agro-ecological goals. In order to illustrate the wicked social, economic and environmental challenges and processes to find transformative solutions, we focus on the largest concentration of greenhouses in the world located in the semi-arid coastal plain of South-east Spain. Almería family farming, predominantly cooperative, greenhouse intensive production, commenced after the 1960s and has resulted in very significant social and economic benefits for the region, while also having important negative environmental and biodiversity impacts, as well as creating new social challenges. The system currently finds itself in a crisis of diminishing economic benefits and increasing environmental and social dilemmas. Here, we present the outcomes of multi-actor, transdisciplinary research to review and provide collective insights for solutions-oriented research on the sustainability of Almeria’s agricultural sector. The multi-actor, transdisciplinary process implemented collectively, and supported by scientific literature, identified six fundamental challenges to transitioning to an agricultural model that aims to ameliorate risks and avoid a systemic collapse, whilst balancing a concern for profitability with sustainability: (1) Governance based on a culture of shared responsibility for sustainability, (2) Sustainable and efficient use of water, (3) Biodiversity conservation, (4) Implementing a circular economy plan, (5) Technology and knowledge transfer, and (6) Image and identity. We conclude that the multi-actor transdisciplinary approach successfully facilitated the creation of a culture of shared responsibility among public, private, academic, and civil society actors. Notwithstanding plural values, challenges and solutions identified by consensus point to a nascent acknowledgement of the strategic necessity to locate agricultural economic activity within social and environmental spheres.This paper demonstrates the need to establish transdisciplinary multi-actor work-schemes to continue collaboration and research for the transition to an agro-ecological model as a means to remain competitive and to create value

Treatment with tocilizumab or corticosteroids for COVID-19 patients with hyperinflammatory state: a multicentre cohort study (SAM-COVID-19)

Objectives: The objective of this study was to estimate the association between tocilizumab or corticosteroids and the risk of intubation or death in patients with coronavirus disease 19 (COVID-19) with a hyperinflammatory state according to clinical and laboratory parameters. Methods: A cohort study was performed in 60 Spanish hospitals including 778 patients with COVID-19 and clinical and laboratory data indicative of a hyperinflammatory state. Treatment was mainly with tocilizumab, an intermediate-high dose of corticosteroids (IHDC), a pulse dose of corticosteroids (PDC), combination therapy, or no treatment. Primary outcome was intubation or death; follow-up was 21 days. Propensity score-adjusted estimations using Cox regression (logistic regression if needed) were calculated. Propensity scores were used as confounders, matching variables and for the inverse probability of treatment weights (IPTWs). Results: In all, 88, 117, 78 and 151 patients treated with tocilizumab, IHDC, PDC, and combination therapy, respectively, were compared with 344 untreated patients. The primary endpoint occurred in 10 (11.4%), 27 (23.1%), 12 (15.4%), 40 (25.6%) and 69 (21.1%), respectively. The IPTW-based hazard ratios (odds ratio for combination therapy) for the primary endpoint were 0.32 (95%CI 0.22-0.47; p < 0.001) for tocilizumab, 0.82 (0.71-1.30; p 0.82) for IHDC, 0.61 (0.43-0.86; p 0.006) for PDC, and 1.17 (0.86-1.58; p 0.30) for combination therapy. Other applications of the propensity score provided similar results, but were not significant for PDC. Tocilizumab was also associated with lower hazard of death alone in IPTW analysis (0.07; 0.02-0.17; p < 0.001). Conclusions: Tocilizumab might be useful in COVID-19 patients with a hyperinflammatory state and should be prioritized for randomized trials in this situatio

Estudo das fases de ataque no basquete infantil masculino: diferenças entre os vencedores e os perdedores

El objetivo del presente estudio es analizar las características de las fases de ataque, y las principales diferencias entre equipos ganadores y perdedores, en categoría infantil masculina. Para ello, se ha aplicado la Metodología Observacional a través de un diseño de seguimiento intersesional, nomotético y multidimensional, analizándose un total de 3079 fases de ataque pertenecientes a los 8 partidos disputados en la Fase Final de la Minicopa Endesa 2015/2016. Los resultados obtenidos indican que el tipo de ataque más usado es el ataque posicional, seguido del contraataque (más efectivo en ganadores), con una duración en torno a los 8 segundos (menor duración en ganadores), con una media de 2,12±1,61 pases realizados y un máximo de 3 jugadores participantes. En cuanto al lugar de fnalización de aquellos ataques que fnalizan en lanzamiento, se encuentra que son mayoritariamente realizados desde posiciones cercanas al aro. Los datos obtenidos indican una escasa participación de los jugadores (tan solo reciben el balón un promedio de 2,69 ± 1,14 jugadores por ataque), así como una escasa efcacia en el lanzamiento, lo que denota una falta de adecuación de la condiciones de práctica a las características de esta etapa.Abstract: Te aim of this study was to analyze the characteristics of the attack phase´s, and the main diferences between winning and losing teams, in boys 14-and-under competition. Observational methodology has been applied through a follow-up, nomothetic and multidimensional design, analyzing a total sample of 3079 phases of attack, belonging to the 8 matches played in the fnal phase of Minicopa Endesa 2015/2016. Te results indicate that the most used type of attack is the positional attack, followed by the counter-attack (more efective in winner team´s), lasting around 8 seconds (shorter duration in winner´s), with an average of 2,12 ± 1,61 passes and no more tan 3 participants. Te places where shot´s are made are mostly positions near the hoop. Te results obtained indicate a low participation of players (an average of 2,69 ± 1,14 player are involved receiving the ball) as well as a very remarkable lack of efcacy. Tat seems indicate that the practice conditions are not adecuate to the characteristics of this stage.Resumo: O objetivo deste estudo é analizar as características das fases de ataque, e as principais diferenças entre as equipas vençedoras e perdedoras em categoria U-14.
