Isolation, Insularity and Resilience: A Review of the Geophysical, Socioeconomic, and Environmental Vulnerabilities of Gran Canaria and Lesvos Islands for Policy Interventions to Global Change

Sustainable Development, EarlyView.
ABSTRACT The dynamic nature of small islands being geographically isolated and their perceived connectedness with global networks complicates research attempts to draw general conclusions on whether insularity leads to marginalization or strengthens their resilience for sustainable development.

In Situ Growth of 2D Perovskite Nanocrystals to Induce β–Phase of PVDF for Piezoelectric Nanogenerators with Ultra‐High Output Voltage

Small, EarlyView.
In situ grown 2D perovskite nanocrystals embedded in PVDF enable flexible piezoelectric nanogenerators with greatly enhanced β‐phase content and a high d33∗${\mathrm{d}}_{33}^{\mathrm{*}}$ of 35.16 pm/V. The devices deliver up to 66.54 V, exhibit light‐enhanced piezoelectricity, and maintain durability over 12000 cycles, offering a stable energy source

Concrete in architecture: Redefining form, space, function, and insights from bibliometric analysis

Structural Concrete, EarlyView.
Abstract Concrete has become a cornerstone in architectural and engineering innovation, as it seamlessly integrates structural performance with artistic expression. Its evolution from ancient opus caementicium to contemporary ultra‐high‐performance concrete illustrates its adaptability to the change in technological, environmental, and design paradigms.

Shear wall plan layout optimization considering seismic loads

Structural Concrete, EarlyView.
Abstract Seismic force resistant structural design requires experience and time. Shear wall elements are generally used in concrete structures due to their high stiffness against horizontal forces. The aim of this study is to obtain optimum structural wall disposition by using building information modeling (BIM) technologies.

Seismikkens ringvirkninger : The impact of seismic surveys

, 2008
Sound is an important means of communication for many species of fish, in terms of feeding, survival and reproduction. The sound waves from seismic guns have low frequencies that overlap the range at which fish hear well. All evidence suggests that fish are not particularly keen on the sound energy produced by seismic surveys.

Influence of steel reinforced grout configuration, and reinforcement ratio on the flexural performance of strengthened continuous RC beams

Structural Concrete, EarlyView.
Abstract The field of reinforced concrete (RC) strengthening continues to evolve as the construction industry seeks cost‐effective and sustainable alternatives to structural replacement. This study, therefore, aimed to comprehensively investigate the pioneering application of steel‐reinforced grout (SRG) for strengthening large‐scale, 3.5‐meter‐long ...

On the preservation of reinforced concrete architectural masterpieces: The challenges of the REcube project

Structural Concrete, EarlyView.
Abstract The preservation of reinforced concrete masterpieces from the 20th century poses a complex challenge. These structures often combine architectural, historical, and technological value, which standard engineering codes and conservation practices are not fully equipped to address. The Erasmus+ REcube project responded to this gap by promoting an

Seismic performance evaluation of a century‐old RC columns for railway's structural concrete

Structural Concrete, EarlyView.
Abstract Since the Great Kanto Earthquake of 1923 in Japan, reinforced concrete (RC) has been adopted for railway bridge piers, and some of these structures, now over 100 years old, continue to support transportation in the capital city of Tokyo. Evaluating the seismic performance of these few remaining RC structures has become an urgent issue. Because
