Modelling the degradation of externally bonded post-tensioning tendons including bond-slip behaviour

In recent years, brittle fractures of externally bonded post-tensioning tendons have been observed in bridges worldwide, compromising structural safety and durability. Consequently, concern has increased about the mechanical behaviour of these elements when strand or wire breakag...

Development of Sustainable Gypsum Composites Incorporating Silica Fume Waste and Fiber Reinforcement for Construction Applications

This study evaluates the feasibility of developing sustainable gypsum composites incorporating silica fume waste and fiber reinforcement for construction applications. The experimental program was divided into two phases. First, silica fume was incorporated into the gypsum matrix...

Sensor System Design and Deployment for Environmental and Visitor Monitoring in Cultural Heritage Sites

In this paper the design, development, and validation of a set of low-power low-cost sensor systems intended for environmental monitoring and visitor tracking in cultural heritage sites are shown. These systems have been deployed in five pilot cases in four different countries in...

Seismic behaviour of aggregated reinforced masonry dwellings considering the combined influence of diaphragm stiffness and height irregularity

Abstract Aggregate dwellings are a common construction configuration in urban environments in the Americas, where space constraints favour terraced construction. However, seismic interaction between adjacent dwellings can significantly alter their structural response, especially...

Transforming viticulture through genomic innovation and integrated pest management for sustainable grape production

Abstract Climate change and intensifying disease pressure push viticulture beyond incremental adaptation, especially where grape production depends on repeated pesticide applications. Reducing chemical inputs requires an integrated strategy combining broader genetic diversity, co...

Performance Assessment of Gypsum-Based Composites with Coconut Fibers: Durability, Circularity, and Environmental Impact Assessment

Gypsum-based composites are widely used in construction for their rapid setting and fire resistance; however, their low mechanical strength and limited durability in humid conditions restrict their use in highly humid indoor environments. In this study, gypsum-based composites we...

Detailed study of non-equilibrium characteristics of quasi-neutral TNSA plasmas

In an experiment performed in November 2022 at the petawatt (PW) laser facility at Vega III located in Salamanca-Spain, we have studied the successful production of several radioisotopes using protons accelerated by the Target Normal Sheath Acceleration (TNSA) mechanism (Rodrigue...

Comparative laboratory analysis of window sound insulation across glazing types in the 50–5000 Hz range: evaluation of different low-frequency methods

This study investigates the sound insulation performance of windows by presenting laboratory measurements from 50 to 5000 Hz on two window types, with and without an integrated shutter box, each tested across five glazing configurations. While all measurements were conducted unde...

Making residential energy retrofits work: How local intermediaries connect municipal policy and household-level action to advance the energy transition in Madrid

Municipalities play a central role in driving urban sustainability transitions but often struggle to engage critical actors necessary for implementing local climate policy objectives. These challenges are especially visible in the slow uptake of household energy retrofit policies...
