Implementation of urban building energy modelling in historic districts. Seville as case-study
Buildings represent 40% of the European Union’s final energy consumption and are largely of resi-
dential use. From 2006 to 2016, existing European housing stocks have been analysed at national
level to make the energy refurbishment processes transparent and effective. However, at the meta-
scale of regions, cities or neighbourhoods, case-by-case analysis using Building Energy Models (BEM)
becomes an unfeasible decision-support tool. To try to overcome this limitation, the nascent field of
Urban Building Energy Modelling (UBEM) is making substantial progress in the assessment of build-
ing energy performance at urban scale. Still, most of the UBEM projects rely upon archetypes – i.e.
virtual or sample buildings illustrative of the most frequent characteristics of a particular category, and
the definition and description of such archetypes may compromise their reliability. This paper presents
an alternative UBEM approach, especially designed for the homogeneous historic districts of cities
where a significant proportion of the buildings are under preservation rules. These rules can restrict
the scope of the measures to improve their energy efficiency or limit the possibility of implementing
renewable energy systems. We introduce a new parameter (HAD) to classify blocks according to their
heritage asset density. HAD is then mapped onto the study-area and the sample block is selected as
representative of the most frequent HAD category. Using the historic ensemble of Seville as case-study,
this paper shows results in energy consumption on a district scale and proposes a set of solutions to
improve the energy efficiency of the buildings while respecting the heritage preservation rules. To sup-
port consistent policy decisions, validation of these results has been carried out, by in-situ monitoring
of a representative number of dwellings
Análisis del tráfico rodado en Bélgica usando Azure
RESUMEN: Hoy en día el Big Data y la nube están en la mayoría de los servicios que utilizamos sin que ni siquiera seamos conscientes. Son una necesidad para el continuo desarrollo a día de hoy. Traffic Monitoring se trata de una plataforma de datos con la cual se procesan los datos que provienen de sensores de tráfico rodado que el gobierno belga tiene instalados a lo largo de sus carreteras. El sistema es capaz de procesar millones de registros por hora a un coste muy bajo a la vez que es capaz de servir resultados e información relevante en un periodo de tiempo muy bajo manteniendo una latencia aceptable a la hora de ofrecer la información en tiempo real.
El producto ha sido desarrollado utilizando tecnologías que están siendo utilizadas por las compañías más punteras del mundo en el momento de su desarrollo como son BP, Alibaba, Tencent Games, McAfee o UpWork como pueden ser Delta Lake o Spark.
ABSTRACT: Nowadays the Big Data and Cloud are in most of the services we use, and we aren’t aware of it. They
are a necessity for our continuous development in the world today. Traffic Monitoring is a data platform built in Azure that processes data retrieved from traffic sensors installed in the Belgium roads by the government.
The system is capable of processing millions of records per hour at a very low cost while at the same time it is able to serve relevant results and information in a very low period of time while maintaining an acceptable latency in providing the information in real time.
The product has been developed using technologies that are being used by the world’s leading companies such as BP, Alibaba, Tencent Games , McAfee or UpWork Some of the technologies are Delta Lake and Spark

Very compact 3D-printed folded branch-line hybrid coupler based on loaded helical-microstrip transmission lines
This paper presents a 3D topology for high miniaturization of the well-known hybrid branch-line coupler at the UHF band. A preliminary work already proposed the use of helical-microstrip TLs combined with a folded structure for this purpose. This extended work includes a compactness enhancement by loading the TL segments with capacitors. An study of loaded helical-microstrip TL is reported as well. The coupler prototypes have been simulated and fabricated by using a combination of Additive Manufacturing and copper electroplating. The performance results have been compared to the conventional model showing a good agreement. In order to place the designed devices within the state of the art a figure of merit that combines the compactness and the relative bandwidth has been proposed, showing very good results in terms of miniaturization

Acute Colchicine-induced Neuromyopathy in a Patient Treated With Atorvastatin and Clarithromycin
Neuromyopathy is a rare side effect of chronic colchicine therapy, especially without renal impairment. Drugs interacting with colchicine metabolism through CYP3A4 can accelerate accumulation and toxicity. We describe a case of an interaction between atorvastatin, clarithromycin and colchicine resulting in acute neuromyopathy.
Learning points: Colchicine has a narrow therapeutic window, and therefore, often produces side effects.Special caution should be adopted if patients with renal disease and concomitant medications are given colchicine.Before prescribing colchicine, the clinical history, including previous medications and conditions, should be carefully considered
Fístula arteriovenosa femoral postraumática, tratamiento endovascular
ResumenAntecedentesLas fístulas arteriovenosas secundarias a arma de fuego han ido en incremento debido a las cuestiones bélicas, mostrando un beneficio en el manejo endovascular para pacientes hemodinámicamente estables.Caso clínicoSe presenta el caso de un paciente masculino 16años de edad con diagnóstico de fístula arteriovenosa femoral en miembro pélvico izquierdo, que ingresó al Servicio de Cirugía para manejo endovascular. Se realizó procedimiento con stent sin complicaciones, egresando del servicio sin complicaciones. Actualmente en tratamiento anticoagulante y antiagregante.ConclusiónLas fístulas arteriovenosas por debajo de la región inguinal pueden ser tratadas de manera segura con terapia endovascular (mediante stents o embolización) en pacientes hemodinámicamente estables. El objetivo del tratamiento es cerrar el defecto entre la arteria y la vena, obliterando el flujo que la nutre. Este fue el caso de este paciente, con buenos resultados tras la terapia endovascular, con lo que disminuyeron las complicaciones del tratamiento quirúrgico.AbstractBackgroundArteriovenous fistulas secondary to gunshot wounds have been increasing due to military activities, with endovascular treatment showing better results in haemodynamically stable patients.Clinical caseA 16 year-old male with diagnosis of femoral arteriovenous fistula in the left lower extremity was admitted to general surgery for endovascular management. A procedure with stent was performed without complications, and is currently on anticoagulant and antiplatelet treatment.ConclusionArteriovenous fistulas under the inguinal region can be safely treated with endovascular treatment (embolisation or stent) on stable patients. The objective of this therapy is to close the defect between artery and vein. This is the case of a patient with great results due to endovascular treatment, decreasing complications of the surgical treatment
La visibilidad de la mujer a través las capitulaciones matrimoniales del mundo rural del norte de Aragón (siglos XVI-XVIII)
Tradicionalmente se ha concedido un papel subordinado a la mujer en las capitulaciones
matrimoniales, documento básico en la regulación del régimen económico de la familia. Sin
embargo, no eran raras las ocasiones en que la mujer alcanzaba protagonismo. El examen de
varios centenares de capitulaciones del Alto Aragón nos ha permitido sacar a la luz esa realidad.
Son muchos los casos en que sus progenitores u otros familiares la eligen como heredera, no
siendo óbice la existencia de hermanos varones. Protagonismo también en las capitulaciones
pactadas mediante la figura del agermanamiento, en el que la mujer aportaba la herencia y el varón
la dote. Finalmente, protagonismo gracias a la viudedad foral, a la que se podía renunciar y que en
ocasiones era sustituida por el “año de manto”, figura semejante al any de plor catalán y valenciano
