La investigación e innovación técnica en una Escuela de Arquitectura

Compared with other productive economic sectors of society, the building sector shows that technological and industrial production techniques are incorporated slowly, which explains in part the slow overall development. This is due mainly to the deep economic crisis that the sector experience cyclically, and the lack of continued research activities. Within this area, the Construction Science Department of the School of Architecture at the University of Navarra has developed a protocol for the development of new technologies to improve and optimize the performance of facade systems, contributing at the same time to the sustainability of material and environmental resources, and the reduction of the final costs of buildings and the costs derived from its service stage.En el sector de la edificación, en comparación con otros sectores económico-productivos de la sociedad, se aprecia que los avances tecnológicos y las técnicas de producción industriales se van incorporando con lentitud, lo cual explica en parte su lento desarrollo global. Esto es debido, fundamentalmente, a las crisis económicas profundas que el sector experimenta cíclicamente, y a la falta de actividades continuadas de investigación. Dentro de este ámbito, en el Departamento de Edificación de la Escuela de Arquitectura de la Universidad de Navarra se ha elaborado un protocolo para el desarrollo de nuevas tecnologías que permitan mejorar y optimizar las prestaciones de los cerramientos de fachadas, contribuyendo también a la sostenibilidad de los recursos materiales y ambientales y a la disminución de los costes finales de los edificios y los derivados de su estado en servicio

A thorough protocol to study and develop constructive systems of façades

In the Department of Construction Science, we have developed and documented a specific model of systematized process in order to carry out activities of R&D&I oriented to a detailed design of constructive systems of innovative façades. This specific model will be used as a guide for the study, analysis, design and evaluation of the proposed solutions for façades. This model of systematized process of research provides a general idea of the set of stages and activities in the processes of R&D&I, with a graphical map and a documentary structure that describes how all the process works, step by step, facilitating its comprehension and application. The protocol details the key procedures within the global process. This protocol allows elaborating the programme of necessities derived from the conditionings, requirements and demands related to every specific façade, assisting with the definition of the technical characteristics of its parts and components to approach the conceptual and graphical design of constructive solutions, in successive stages. This protocol provides the means to analyze and evaluate every particular design of façade and the process of R&D&I that has been followed, so that it allows to justify and demonstrate the fulfilment of the requirements and demands that concern every stage of the complete life cycle of façades, and to identify fields that could be improved in the R&D&I process, in order to apply corrective actions. This protocol is complemented by some Supporting Technical Documents, where the scientific and technical criteria and the information from compulsory regulations that are necessary to take decisions in the design progress, are developed. On the whole, it is a useful tool that allows rapid availability of knowledge and rigorous information related to the process of R&D&I, to the constructive systems of façades and to the activity of the diverse agents involved in the building process

Es necesario rotular con más claridad los tubos emisores de luz ultravioleta C para la prevención de lesiones en la piel y los ojos

La queratoconjuntivitis actínica se produce por la exposición del ojo sin protección a los rayos ultravioleta, sobre todo de los tipos B y C (UV-B y UV-C). Consiste en una inflamación superficial del ojo muy molesta, que produce sensación de cuerpo extraño, dolor, lagrimeo y fotofobia, con una duración de 12-24 horas. Normalmente no hay secuelas, aunque en ocasiones pueden producirse úlceras corneales. En la mayoría de los casos se debe al uso de equipos de soldadura o a focos de luz potentes..

Role of age and comorbidities in mortality of patients with infective endocarditis

Purpose: The aim of this study was to analyse the characteristics of patients with IE in three groups of age and to assess the ability of age and the Charlson Comorbidity Index (CCI) to predict mortality. Methods: Prospective cohort study of all patients with IE included in the GAMES Spanish database between 2008 and 2015. Patients were stratified into three age groups:<65 years, 65 to 80 years, and = 80 years.The area under the receiver-operating characteristic (AUROC) curve was calculated to quantify the diagnostic accuracy of the CCI to predict mortality risk. Results: A total of 3120 patients with IE (1327 < 65 years;1291 65-80 years;502 = 80 years) were enrolled.Fever and heart failure were the most common presentations of IE, with no differences among age groups.Patients =80 years who underwent surgery were significantly lower compared with other age groups (14.3%, 65 years; 20.5%, 65-79 years; 31.3%, =80 years). In-hospital mortality was lower in the <65-year group (20.3%, <65 years;30.1%, 65-79 years;34.7%, =80 years;p < 0.001) as well as 1-year mortality (3.2%, <65 years; 5.5%, 65-80 years;7.6%, =80 years; p = 0.003).Independent predictors of mortality were age = 80 years (hazard ratio [HR]:2.78;95% confidence interval [CI]:2.32–3.34), CCI = 3 (HR:1.62; 95% CI:1.39–1.88), and non-performed surgery (HR:1.64;95% CI:11.16–1.58).When the three age groups were compared, the AUROC curve for CCI was significantly larger for patients aged <65 years(p < 0.001) for both in-hospital and 1-year mortality. Conclusion: There were no differences in the clinical presentation of IE between the groups. Age = 80 years, high comorbidity (measured by CCI), and non-performance of surgery were independent predictors of mortality in patients with IE.CCI could help to identify those patients with IE and surgical indication who present a lower risk of in-hospital and 1-year mortality after surgery, especially in the <65-year group

Effect of dietary supplementation of palm fruit extracts on the transcriptomes of growth, antioxidant enzyme and immune-related genes in common carp (Cyprinus carpio) fingerlings

This study investigates the effects of date palm extracts [DPE] (Phoenix dactylifera L. Arecaceae) on growth, immune function and antioxidant system in common carp fingerlings (Cyprinus carpio). One hundred and twenty fish (4.06 ± 0.13 g) were divided into six groups fed on control diet or diets containing 200 mL kg−1 DPE for 8 weeks. At the end of feeding trial, the expression of different genes was measured. Selected genes were grouped into three categories: growth factor genes in brain and liver [growth hormone (GH), insulin-like growth factors I and II (IGF-I and IGF-II), antioxidant-related genes in liver [glutathione S-transferase-alpha (GST-α), glutathione reductase (GR) and glutathione peroxidase genes (GPX)] and immune-related genes in head kidney [interleukin-8 (IL-8), interleukin-10 (IL-10) and transforming growth factor-beta (TGF-β) genes]. The relative expression of the growth-related genes in fish fed DPE showed no significant increase compared to control group (P > 0.05). On the other hand, DPE altered the expression of genes encoding antioxidants enzymes in liver of fingerlings which was statistically significant with respect to the control samples in case GPX (P < 0.05). Also, DPE caused remarkable increases in the expression of the immune-related genes (IL-8, IL-10 and TGF-β) analysed on head kidney of common carp fingerlings compared to the control group (P < 0.05). In conclusion, it can be suggested that administration of DPE in early stages of common carp culture can promote immune efficacy and increase the antioxidant activity. © 2016 John Wiley & Sons Lt

Effects of elephant's foot (Elephantopus scaber) extract on growth performance, immune response, and disease resistance of nile tilapia (Oreochromis niloticus) fingerlings

Medicinal plant has been applied as an alternative strategy for antibiotics and chemotherapeutics for controlling the outbreak of diseases in tilapia farming. In this study, five doses of Elephantopus scaber extract (ESE) were added to the basal diet at 0, 2.5, 5, 10, and 20 g kg−1 feed of Nile tilapia fingerlings (13.92 ± 0.06 g initial weight) in triplicate. After 4- and 8- weeks post-feeding, fish were sampled to determine the effects of the ESE supplemented on fish's growth performance, humoral, and skin mucus immune response. After 8 weeks post-feeding, a challenge test against Streptococcus agalactiae was carried out using 10 fish from each tank. Fish fed ESE showed significantly increased serum lysozyme (SL), serum peroxidase (SP), alternative complement (ACH50), phagocytosis (PI), and respiratory burst (RB) compared to the control group (P < 0.05). The skin mucus lysozyme (SMLA) and skin peroxidase (SMPA) were stimulated in fish fed ESE diets. Dietary inclusion of ESE significantly (P < 0.05) promoted final body weight (FW), weight gain (WG), and specific growth rate (SGR); while a reduction in feed conversion ratio (FCR) was observed in fish fed 5 g kg−1 ESE, after 8 weeks post-feeding. The challenge study indicated that the relative percent survival (RSP) was 38.10%, 76.19%, 66.67%, and 47.62% in Diet 2, Diet 3, Diet 4, and Diet 5, respectively. Among the supplemented groups, dietary of 5 g kg−1 ESE showed significantly higher RPS and the highest resistance to S. agalactiae in comparison with other groups. In conclusion, supplementation of ESE (5 g kg−1) enhanced the humoral and mucosal immunity, promoted growth performance, and improved disease resistance of Nile tilapia against Streptococcus agalactiae

Analysis of passive solar systems of Norman Foster's EDF Building, Bordeaux

In the regional headquarters of EDF (Electricite de France) in Bordeaux, designed by Foster and Partners and built in 1996, the HVAC (Heating, Ventilating, and Air Conditioning) system and the facades form an ensemble aiming to ensure an efficient thermal behaviour. The design of the louvers that protect against solar radiation is optimized according to the orientation of the facades. In addition, the building has a centralized computer system for the management of HVAC installations and a series of automation and control sensors supporting them. A computer analysis of the louvers is made, in order to assess the suitability of the selected design to achieve the energy saving targets proposed by the architects. The site visits and interviews with users allowed us to know their level of satisfaction with the implemented energy-saving systems and with the performance of the entire building
