Impact of the self-healing agent composition on material characteristics of bio-based self-healing concrete

open access: yesCase Studies in Construction Materials, 2019
This paper investigates the composition of the biological self-healing agent based on its impact on material characteristics of concrete. A direct addition of the agent – a mixture of bacterial spores and nutrients – into concrete matrix has been ...

Analysis of behaviour of composite elements with profiled steel sheet/Lenkiamųjų kompozitinių elementų, armuotų profiliuotais metalo lakštais, darbo analizė

open access: yesJournal of Civil Engineering and Management, 2001
Joint action at the interface of concrete and profiled steel sheet layers of composite structures can be achieved in various ways. In most cases different types of roughness (embossments) are made inside sheet waves, which increase mechanical bond ...

Prospecting of Architectural Features Using LiDAR‐UAV Technology, Deep Neural Networks and Visualization Techniques: A Case Study in Kuélap and Cambolín (NW Peru)

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT High‐resolution and accurate synoptic images of terrestrial topography, even in densely forested areas, have proven valuable for archaeology by enabling the identification and characterization of relief patterns associated with ancient human activities. This study presents a novel approach that integrates digital terrain models (DTMs) obtained

From Material Tensions to Organizational Paradoxes: How Manufacturers Cope With the Limits of Circular Product Design

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Circular product design (CPD) is central to advancing the circular economy by enabling the narrowing, slowing, and closing of resource flows. Yet, its implementation remains persistently challenging for firms. Prior research has largely framed these challenges as discrete barriers, overlooking the structural contradictions embedded in CPD ...

Digital documentation of railway tunnel inspection in Austria

open access: yesCivil Engineering Design, Volume 7, Issue 1, Page 3-8, March 2025.
Abstract Infrastructure, especially railway tunnels, require continuous inspection to ensure their safety. Furthermore, the detection of damages at an early stage can improve their service life. These tasks represent a major challenge for those involved and the tunnel down time is a disruption in operation.
