With the addition of electrically conductive steel or carbon fibers, Ultra-High-Performance Concrete (UHPC) possesses an intrinsic self-sensing capability. This opens up the possibility of combining the resilience and sustainability of UHPC with the development of self-sensing solutions for structural applications. In this study, the self-sensing behaviour of a proprietary nano-engineered UHPC material subjected to tension was investigated. To assess the self-sensing performance of the material, bulk resistivity measurements were used on direct tension and pure flexure tests, while a novel wireless approach that operates on was used on out-of-plane bending tests. The wireless approach used alternate current (AC) measurements while the bulk resistivity methods were performed through direct current (DC) and the four-probe method. In both methods, the fractional change in resistance was correlated to the state of deformation. The disposition of the actual strain field was evaluated using Digital Image Correlation (DIC). It was found that in the case of direct tension and pure flexure, the fractional change of resistance was initially decreased up to the onset of strain localization, while it gradually increased in the post-peak range, where the separation of the localized crack gradually increased. In the case of the wireless approach using AC, the onset of cracking was successfully predicted with an abrupt increase in resistivity. The wireless strain-sensing approach also captured the Poisson's effect due to the loading. [ABSTRACT FROM AUTHOR]

Objective: This study aimed to develop a healthy body image package for adolescents aged 12 to 15 years with body image dissatisfaction. Methods and Materials: The research method was a theory-driven deductive thematic analysis. In the qualitative content determination phase, the content, structure, and final form of the healthy body image package were developed using a five-step method based on theory-driven thematic analysis in line with Attride-Stirling's (2001) thematic network analysis. The statistical population included scientific texts related to a healthy body image and experts in the field of adolescent psychotherapy. Purposeful sampling was employed based on the content relevance of 30 scientific texts to strategies for promoting a healthy body image in adolescents until theoretical saturation was reached. Additionally, 6 expert psychotherapists with more than 10 years of experience in adolescent psychotherapy participated. Data were analyzed using theory-driven thematic analysis. Findings: The findings indicated that the content of the healthy body image package included four main concepts: perceptual strategies training, emotional strategies training, cognitive strategies training, and behavioral strategies training. The content validity of the educational package was equal to 1. Conclusion: According to the results of the present study, it is suggested that this educational package be taught to managers, teachers, and counselors to reduce body image dissatisfaction in adolescents.
