La ventana modular aplicada en la rehabilitación

La ventana tradicional en España, a pesar de responder básicamente a unas premisas comunes, varía según la zona. Sin embargo, todas ellas tienen en común, funcionalmente, los siguientes aspectos: Iluminación natural. Ventilación natural. Contacto visual con el exterior. Hoy en día las ventanas siguen siendo prácticamente iguales a las tradicionales, solo hay mejoras a través de la incorporación de materiales de protección térmica y acústica. En el proyecto INVISO (Industrialización de Viviendas Sostenibles) -subproyecto 10 (Sistemas para la optimización del comportamiento eficiente de las viviendas)- que se está desarrollando en la Escuela Técnica Superior de Arquitectura de Madrid, en relación con los huecos de fachada, se ha diseñado el prototipo llamado VENTANA MODULAR, que integra estrategias tradicionales y mejora notablemente la iluminación y climatización del espacio interior. La ventana modular, es un prisma rectangular, una doble envolvente dinámica, que se modifica de acuerdo a las necesidades y que contiene los elementos necesarios para responder a los cambios estacionales, tanto diurnos como nocturnos. La ventana se caracteriza por lo siguiente: Permite al usuario controlar su propio ambiente interior. Favorece la iluminación natural y el contacto visual con el exterior. Permite la ventilación natural en todo momento. Protege las superficies acristaladas de la radiación solar directa y disminuye las demandas de energía en climatización. Protege el interior del espacio del exceso de ruido exterior. Mariano Vázquez Espí, refiriéndose a la rehabilitación, dice "...llegará el momento en el que solo haga falta rehabilitar o reutilizar, en el que la obra nueva sea una rareza, no la regla... de más de tres millones de viviendas construidas en España en la década de los ochenta, medio millón largo quedaron vacías, desocupadas, lo que representa la sexta parte de lo construido...”

Good and bad practices in pv plants

The PVCROPS project (PhotoVolta ic Cost r€duction, Reliability, Operational performance, Prediction and Simulation), cofinanced by European Commission in the frame of Seventh Framework Programme, has compiled in the “Good and bad practices: Manual to improve the quality and reduce the cost of PV systems” a collection of good and bad practices in actual PV plants . All the situations it collects represent the state-of-the-art of existing PV installations all around Europe. They show how the different parts of an installation can be implem ented properly or not. The aim of this manual is to represent a reference text which can help any PV actor (installers, electricians, maintenance operators, owners, etc.) not only to check and improve an already existing installation but will also, and mainly, avoid the previously known bad practices for the construction of a new PV installation. Thus, solving a priori the known errors, new PV installations will be more reliable, efficient and cost-effective and can recover the initial investment in a shorter time. The manual is going to be free available in the PVCROPS website in several languages

Comparative retention and effectiveness of migraine preventive treatments: A nationwide registry-based cohort study

Background and purpose Little is known about the comparative effects of migraine preventive drugs. We aimed to estimate treatment retention and effectiveness of migraine preventive drugs in a nationwide registry-based cohort study in Norway between 2010 and 2020. Methods We assessed retention, defined as the number of uninterrupted treatment days, and effectiveness, defined as the reduction in filled triptan prescriptions during four 90-day periods after the first preventive prescription, compared to a 90-day baseline period. We compared retention and efficacy for different drugs against beta blockers. Comparative retention was estimated with hazard ratios (HRs), adjusted for covariates, using Cox regression, and effectiveness as odds ratios (ORs) using logistic regression, with propensity-weighted adjustment for covariates. Results We identified 104,072 migraine patients, 81,890 of whom were female (78.69%) and whose mean (standard deviation) age was 44.60 (15.61) years. Compared to beta blockers, botulinum toxin (HR 0.43, 95% confidence interval [CI] 0.42–0.44) and calcitonin gene-related peptide pathway antibodies (CGRPabs; HR 0.63, 95% CI 0.59–0.66) were the least likely to be discontinued, while clonidine (HR 2.95, 95% CI 2.88–3.02) and topiramate (HR 1.34, 95% CI 1.31–1.37) were the most likely to be discontinued. Patients on simvastatin, CGRPabs, and amitriptyline were more likely to achieve a clinically significant reduction in triptan use during the first 90 days of treatment, with propensity score-adjusted ORs of 1.28 (95% CI 1.19–1.38), 1.23 (95% CI 0.79–1.90), and 1.13 (95% CI 1.08–1.17), respectively. Conclusions We found a favorable effect of CGRPabs, amitriptyline, and simvastatin compared with beta blockers, while topiramate and clonidine were associated with poorer outcomes.publishedVersio

Telescopic crowns in adult case with lip and palate cleft : update on the etiology and management

Lip and palatal clefts are among the most important congenital craniofacial malformations to be taken into account in general dental practice, due to their high incidence and important repercussions upon the oral cavity. The underlying causes are genetic and fundamentally environmental, and the disorders manifest as early as in the embryonic period. Males are predominantly affected, with a 7:3 ratio versus females. Our patient, a 20-year-old male, presented the most common association, i.e., total unilateral hare lip with palatal cleft. A description is provided of the treatment for his dental problem, together with an update on the etiology and management of adults with malformations of this kind
