Pullout performance of steel bars partially bonded in concrete with epoxy resin

open access: yesRevista IBRACON de Estruturas e Materiais, 2018
The installation of new reinforcing bars onto an existing structure is a common practice in civil construction both for old and new structures. The use of anchors has been extensively studied and normalized.

Intra‐ and Interspecific Effects on Spatio‐Temporal Behavior of Common Commensal Rodent Species

open access: yesIntegrative Zoology, EarlyView.
This study revealed major findings on spatio‐temporal behavior of commensal rodents on a pig farm showing the influence of interspecific dominance on movement behavior and the resulting species‐specific ecological adaptations. Additionally, rodents tend to stay in their home ranges and migration to other stable buildings is only rare.

Occupational Contact Allergy to Components of Epoxy Resin Systems: Descriptive and Comparative Epidemiological Analyses Based on IVDK Data 2008–2022

open access: yesContact Dermatitis, EarlyView.
This study analyzes patch test data from 23 969 patients with occupational dermatitis to characterise sensitization to bisphenol A diglycidyl ether (DGEBA), reactive diluents, and amine hardeners. The findings show an overall decline in DGEBA sensitization with fluctuations, substantial co‐sensitization, and markedly increased risks in construction ...

Enhanced Bond Performance of Guadua-Reinforced Concrete Synergistic Effects of Epoxy Resin and Grooved Surface Treatments

open access: yesJournal of Applied Science and Engineering
This study investigates the bond behavior between concrete and Guadua angustifolia Kunth bamboo using a pull-out test adapted from ASTM C234. A multifactorial experimental design was employed to evaluate two key treatment parameters: surface texture ...

Histology and fossil diagenesis of a pterosaur tooth from the Crato Formation (Lower Cretaceous of Brazil)

open access: yesThe Anatomical Record, Volume 309, Issue 10, Page 2739-2751, October 2026.
Abstract Pterosaur dental biology remains poorly understood despite its importance for comprehending feeding strategies and flight adaptations. Here, we present the first comprehensive histological analysis of an ornithocheiriform pterosaur tooth from the Lower Cretaceous Crato Formation (Santana Group, Northeast Brazil).

Exploring the Use and Impact of Composite Materials in Robotics: A Systematic Review

open access: yesJournal of Field Robotics, Volume 43, Issue 6, Page 4037-4060, September 2026.
ABSTRACT Lightweight and high‐strength materials are important in robotics, as structural design impacts efficiency, payload capacity, and energy consumption. Composite materials, with their superior stiffness‐to‐weight ratios and multifunctional properties, offer clear advantages over conventional metals and polymers.

Epoxi resins in concreting joints

open access: yesInformes de la Construccion, 1966
As is well known, epoxi resins are overcoming a large number of problems in various fields of industry. In construction their use promises to be useful in many aspects. Concreting joints is a problem which is not well solved. Faced with the possibility that this difficulty can be finally settled by the use of epoxi resins, the Eduardo Torroja Institute
