Tipología estructural de los corrales tradicionales de barro en el Páramo de León

Una de las construcciones agrarias tradicionales peninsulares más emblemáticas es la casa de corral, caracterizada por disponer sus partes en torno a un espacio descubierto. De entre todos los tipos de casas de corral, quizá una de las más típicas sea la existente en la comarca del Páramo de León, que pertenece a la denominada arquitectura del barro castellana. Sus pueblos y construcciones son representativas del tipo general de la Meseta Central, abundando los edificios de adobe y tapial. Sus edificaciones muestran pocos huecos a la calle, volcándose la casa hacia el interior del corral

A World Wide Web-Based Practice That Disseminates Photogrammetry. Inspiring secondary students to pursue geomatics careers

This is the accepted version of a manuscript published in IEEE Geoscience and Remote Sensing Magazine. ISSN: 2168-6831. https://doi.org/10.1109/MGRS.2018.2876565The D3MOBILE Metrology World League was established in 2013 with the aim of encouraging curiosity and interest in science, and particularly geoscience, in the secondary students of grades ISCED 1 and 2. Presented as an international championship, D3MOBILE introduces students to the discipline of photogrammetry through the e-learning methodology concept. The use of well-known technologies by the pupils, such as their own mobile devices (smartphones or tablets), allows us to develop educational procedures that are attractive and challenging for them. All the work that we propose for the participants is presented in a scientific, technical, and professional language but in a more interactive format than traditional textbooks or theoretical classes. The proposed challenges provide students with the opportunity to establish their own learning objectives, work as a team and take responsibility for their work. This paper addresses the experience, from an educational perspective, carried out by our research group CIGEO (Civil Engineering and Geomatics) during the organization of the first five editions of this international “concept submission competition”. During this period, we tried to create and improve a project-based learning (PBL) methodology that can be adapted to e-learning and daily classwork at the high school level, which can be easily implemented regardless of the number of participants and can be implemented anywhere in the world. The obtained results demonstrate the potential of alternative teaching methods combined with new technologies to engage students in science learning and improve the perception of the geosciences as a job opportunityWe thankfully acknowledge the financial support from FECYT—Ministerio de Economía y Competitividad (FCT 12-3495; FCT 13-5961; FCT 14-8038; FCT 15-9481); and Xunta de Galicia (ED431B22016/030; ED341DR2016/023).

Análisis tipológico de las estructuras de las construcciones rurales tradicionales de barro. La casa de corral en el Páramo de León (España)

Traditional rural buildings reflect the building techniques inherited from ancestors, where materials mastery is proved. In this job we analyse the structure of one of the most relevant Spanish traditional agrarian building: the "casa de corral"(yard house). Thirty seven "corrales" (yards) of the vernacular earthen construction in the "Páramo de León"(León, Spain) were analysed. It was necessary think up an analysis method, which we called "round analysis method". Generally. radial cross sections of the yard have a main space between two earth walls bearing over stone foundation, which support floor framing, the roof framing, roof sheathing and arabic curved tiles. A gantry is usually built inward the yard, on a stone baseLas construcciones rurales tradicionales suelen reflejar el buen hacer de quienes han heredado las técnicas de sus antepasados, demostrando un dominio admirable de los materiales. En este trabajo nos centramos en el análisis estructural de uno de los edificios más emblemáticos de las construcciones agrarias tradicionales peninsulares: la casa de corral. Se analizaron 37 de estos edificios, uniformemente repartidos por la comarca del Páramo de León (España). pertenecientes a la denominada construcción de barro rural tradicional contemporánea. Para llevar a cabo el estudio fue necesario idear el denominado método giratorio de análisis. en virtud del cual se realizan sucesivos cortes radiales al corral. Esto nos permitió establecer las características constructivas más relevantes de dichos edificios. En general. las secciones radiales del corral suelen contar con un volumen principal de gruesos muros de carga a base de tapial sobre cimiento de piedra. sustentando los forjados y la estructura de cubierta, cuya impermeabilidad se logra mediante teja árabe. dispuesta sobre enlabiado de madera o sobre rama entretejida. Hacia el interior del corral se suele construir el corredor porticado, cuyos soportes transmiten las cargas al terreno mediante una basa pétrea. En cubierta aparecen fundamentalmente tres tipos de estructuras: en parhilera, en tijera y cerchas de pendolón y tornapunta

A PBeL for training non-experts in mobile-based photogrammetry and accurate 3-D recording of small-size/non-complex objects

The high level of automation, user-friendliness and cost-effectiveness of photogrammetry have contributed significantly to its popularisation among amateur users in recent years. Paradoxically, this situation poses challenges when relying on the accuracy of the derived 3-D products requiring control procedures to be implemented. In this context, we present a case study of the D3Mobile project: a fully online competition for participants worldwide funded by the International Society of Photogrammetry and Remote Sensing (ISPRS). The aim is for participants to obtain reality-based 3-D models using their own mobile phones and to critically examine the metric accuracy that hides behind the beguiling realism of photogrammetry. The relative precision of the former participants’ models reached values around 1:2,000, proportionally to the object size. These results provide an idea of the current level of development of photogrammetry and the potential it offers for any kind of user after proper capacity building and trainingS

Congenital hyperinsulinism in two siblings with ABCC8 mutation: same genotype, different phenotypes

Congenital hyperinsulinism (CHI) is a heterogenous disease caused by insulin secretion regulatory defects, being ABCC8/KCNJ11 the most commonly affected genes. Therapeutic options include diazoxide, somatostatin analogues and surgery, which is curative in focal CHI. We report the case of two siblings (born two years apart) that presented themselves with hypoketotic hyperinsulinemic persistent hypoglycemias during neonatal period. The diagnosis of diffuse CHI due to an ABCC8 compound mutation (c.3576delG and c.742C>T) was concluded. They did not benefit from diazoxide therapy (or pancreatectomy performed in patient number 1) yet responded to somatostatin analogues. Patient number 1 developed various neurological deficits (including epilepsy), however patient number 2 experienced an entirely normal neurodevelopment. We believe this case shows how previous knowledge of the firstborn sibling's disease contributed to a better and timelier medical care in patient number 2, which could potentially explain her better neurological outcome despite their same genotype.S
