Amortización de instalaciones fotovoltaicas en régimen de autoconsumo

100 páginas.Trabajo Fin de Máster en Tecnología de los Sistemas de Energía Solar y Fotovoltaica (2013/14). Tutor: Juan de la Casa Higueras. Desarrolla una herramienta de simulación que permite evaluar el plazo de amortización de las instalaciones fotovoltaicas operando en la modalidad de autoconsumo, bajo cuatro perfiles de consumo predominantes en el entorno urbano, el perfil residencial, el perfil del comercio minorista, oficinas y pymes, el perfil de restauración y el hotelero. El estudio se orienta hacia pequeñas y medianas instalaciones principalmente sobre cubiertas y tejados. Para simular las condiciones de radiación solar de las ubicaciones, se desarrolla un modelo de radiación solar horario con un comportamiento diario variable para cada mes, a partir del modelo de radiación horario basado en el día medio de cada mes. Dado el actual estado de indefinición del régimen económico que será de aplicación al autoconsumo, en el cálculo de los posibles escenarios se contemplan opciones de peajes de respaldo, neteos horarios, diarios, semanales, mensuales y anuales, para todas las tarifas de baja tensión que están actualmente en vigor. También se contempla la posible comercialización de los excedentes de energía de la generación. El resultado de las simulaciones permite evaluar el comportamiento del parámetro económico DPBT (Discount Pay Back Time) o Plazo de Recuperación con Descuento frente al yield y frente al coste de instalación

Preventing Emotional Dysregulation: Acceptability and Preliminary Effectiveness of a DBT Skills Training Program for Adolescents in the Spanish School System

Emotional dysregulation is a key factor in the development and maintenance of multiple disabling mental disorders through a person’s lifespan. Therefore, there is an urgent need to prevent emotional dysregulation as early as possible. The main aim of this study was to evaluate the acceptability and preliminary effectiveness of an adapted Dialectical Behavior Therapy Skills Training program for Emotional Problem Solving in Adolescents (DBT STEPS-A) during secondary school. The sample included 93 adolescents (mean age = 12.78; SD = 0.54; and 53% female) studying in their 2nd year of secondary school in a public center in Catalonia (Spain). Measures of acceptability, difficulties of emotional regulation, mental health problems, and life satisfaction were completed before and after participation in the DBT STEPS-A program during one academic year. The majority of students rated the program as useful (64%) and enjoyed the classes (62%) and 48% of them reported practicing the newly learned skills. Statistically significant improvements were revealed in some emotional regulation-related variables, namely the number of peer problems (p = 0.003; d = 0.52) and prosocial behaviors (p < 0.001; d = −0.82). Although non-significant, the scores in the remaining outcomes indicated a general positive trend in emotional dysregulation, mental health, and life satisfaction. The adapted DBT STEPS-A was very well-accepted and helped overcome some emotional regulation difficulties in Spanish adolescents

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
