Applicability of a parametric and semantic model for the HBIM project of the Church of the Company of Jesus in Quito
(Springer, 2015) Nieto Julián, Juan Enrique; Antón García, Daniel; Lara Calderón, Lenin; Universidad de Sevilla. Departamento de Expresión Gráfica y Arquitectónica; Universidad de Sevilla. Departamento de Expresión Gráfica e Ingeniería en la Edificación
This research addresses the parametric and semantic heritage modelling of the Church of the Company of Jesus in Quito, Ecuador, within the Historic Building Information Modelling (HBIM) context to manage information and
support its preventive conservation and maintenance. The construction, architectural and artistic particularities of this emblematic example of the Latin American
Baroque of the Jesuit order, built from 1605 to 1765, require an exhaustive 3D digital replica. An accurate model enables programmed actions in a comprehensive
management project and further monitoring of the asset.
Massive data acquisition technologies, e.g., Terrestrial Laser Scanning (TLS)
and Structure-from-Motion photogrammetry, greatly help capture the real state
of historic constructions. These protocols provide accurate details that enrich the
building’s intrinsic database—structure, materiality, evolution and metamorphosis—and are constantly updated to support future interventions. A large library of
heritage objects that supports the 3D model of the historic building is pursued. To
face this challenge, progress must still be made to effectively implement unstructured data organisation processes and semantic classification by architectural and
artistic typologies.
This work addresses the analysis and implementation of semi-automatic
modelling techniques for accurate heritage representation. Based on TLS data,
this Scan-to-mesh-to-BIM workflow culminates in the creation of 3D parametric objects. The methodological process developed explores several complementary paths to automate modelling processes, whether parts or complete historical
systems, to reinforce the HBIM project.
Courtyards as passive climate buffers: Enhancing thermal comfort and preventive conservation in mediterranean climates
(Elsevier, 2015) Torres González, Marta; Rodríguez Antuña, Luis; Bienvenido Huertas, José David; Alducín Ochoa, Juan Manuel; León Muñoz, Miguel Ángel; Rubio Bellido, Carlos; Universidad de Sevilla. Departamento de Ingeniería Gráfica; Universidad de Sevilla. Departamento de Construcciones Arquitectónicas II (ETSIE)
This study examines the role of Mediterranean courtyards as passive systems for mitigating extreme climatic conditions while enhancing thermal comfort and preserving architectural heritage. Using the Courtyard of the Maidens in the Royal Alcázar of Seville as a case study, the research includes a three-year monitoring campaign (2020–2023) to collect ambient temperature and relative humidity data, assessing seasonal variations and the impact of heatwaves.
Key findings demonstrate that the courtyard moderates extreme temperatures, reducing reliance on active cooling and heating systems, and contributes to improved comfort levels for users. Additionally, the study highlights the courtyard’s role in minimising environmental stress on heritage materials, particularly its ability to maintain conditions favourable for the conservation of plasterwork and other decorative elements.
The study underlines the importance of integrating passive architectural strategies, such as courtyards, into urban planning to promote sustainability and resilience in Mediterranean climates increasingly affected by climate change. It offers valuable insights into how historic architectural features can address contemporary environmental challenges.
Current challenges and practical aspects of molecular pathology for bone and soft tissue tumors
(Springer, 2024-01-23) Álava Casado, Enrique de; Universidad de Sevilla. Departamento de Citología e Histología Normal y Patológica; Universidad de Sevilla. CTS1035: Patología Molecular del Cáncer Sólido
This review shows the extraordinary change molecular pathology has induced in the classification, diagnosis, and clinical
practice of molecular pathologists dealing with sarcomas. We have primarily focused on the practical aspects of molecular
studies and the current and mid-term challenges for our subspecialty, ending with ten tips for the next generation of sarcoma
molecular pathologists.
Guidance for Establishing and Applying Tolerable Upper Intake Levels for Vitamins and Essential Minerals
(Wiley-Blackwell, 2024) Turck, Dominique; Bohn, Torsten; Cámara, Montaña; Castenmiller, Jacqueline; de Henauw, Stefaan; Hirsch-Ernst, Karen Ildico; Jos Gallego, Ángeles Mencía; Maciuk, Alexandre; Mangelsdorf, Inge; McNulty, Breige; Naska, Androniki; Universidad de Sevilla.

Vitamins and essential minerals are micronutrients that are required for the normal functioning of the human body. However, they may lead to adverse health effects if consumed in excess. A tolerable upper intake level (UL) is a science-based reference value that supports policy-makers and other relevant actors in managing the risks of excess nutrient intake. EFSA's principles for establishing ULs for vitamins and minerals were originally developed by the Scientific Committee on Food in 2000. This guidance from the EFSA Panel on Nutrition, Novel Foods and Food Allergens provides an updated framework for UL assessments. A draft was published in 2022 and underwent a 2-year piloting period. The present document incorporates revisions based on the experience gained through its practical implementation. It covers aspects related to the planning of the risk assessment (problem formulation and definition of methods) and its implementation (evidence retrieval, appraisal, synthesis, integration, uncertainty analysis). As in the previous framework, the general principles developed for the risk assessment of chemicals in food are applied, i.e. hazard identification, hazard characterisation, intake assessment, risk characterisation. Specific to nutrients are their biochemical and physiological roles and the specific and selective mechanisms that maintain the systemic homeostasis and accumulation of the nutrient in the body. Such considerations must also be taken into account when conducting risk assessments of nutrients.
Thermomagnetic liquid metal switches with fast bidirectional response
(Springer Nature, 2025-03-17) Chen, Haodong; Xie, Yuyu; Qiao, Kaiming; Xie, Longlong; Yu, Ziyuan; Xu, Chenyu; Liu, Jingyi; Liu, Mingze; Lu, Yongyu; Law, Jia Yan; Franco García, Victorino; Zhang, Hu; Universidad de Sevilla.

Traditional thermal switches usually suffer from long-time and unidirectional response. Herein, we combined liquid metals with magnetic Ni2Mn1.4In0.6 particles and developed a thermomagnetic liquid metal. These materials not only show excellent fluidity and electrical conductivity, but also exhibit fast response at a tuneable temperature that traditional magnetic liquid metals do not have. The ultimate application is designed as micro-channel thermal switch. Particularly, our thermal switch features bidirectional response through the droplet displacement, thus simultaneously cutting off the working circuit while turning on the fire extinguishing. Its response time of 1.2 s is 3.3 − 5.6 times faster than typical commercial thermal switches under the same hot source temperature of 75 °C, and it can be further reduced to 660 ms under the optimal environment. Moreover, this fast-response thermal switch offers the fastest recovery time, low cost, and long-cycle stability, showing a huge potential as a generation of thermal switches for diverse applications.
