Application of Fractional Calculus in Predicting the Temperature-Dependent Creep Behavior of Concrete

open access: yesFractal and Fractional
Creep is an essential aspect of the durability and longevity of concrete structures. Based on fractional-order viscoelastic theory, this study investigated a creep model for predicting the temperature-dependent creep behavior of concrete.

Comparison of Creep Prediction Models for Self-Compacting and Conventional Concrete [PDF]

open access: yes, 2011
Realistic prediction of concrete creep is of crucial importance for durability and long-term serviceability of concrete structures. To date, research about the behaviour of self-compacting concrete (SCC) members, especially concerning the long-term ...

DNA (cytosine‐5)‐methyltransferase 3A (Dnmt3a) mutations limit normal and autoreactive CD4+ T follicular helper responses and attenuate T cell‐driven joint inflammation

open access: yesArthritis &Rheumatology, Accepted Article.
Objective Somatic DNMT3A mutations are the most common drivers of clonal hematopoiesis in patients with rheumatoid arthritis (RA) and have been associated with seropositive disease and increased inflammatory markers. These mutations are predominantly hypomorphic or dominant‐negative, reducing DNMT3A function.

Monitoring random vehicle load information-based time-varying reliability analysis of PC bridge considering concrete cyclic creep effects

open access: yesAdvances in Bridge Engineering
During the long-term service periods of Prestressed Concrete(PC) continuous girder bridges, structural time-varying reliability will degrade due to cyclic creep induced by dynamic vehicle loading, which increases the risk of structural failure.

Concrete Deformations under Simultaneous Impact of Loading and Alternate Freezing and Thawing

open access: yesMATEC Web of Conferences, 2017
To the best knowledge available today, the creep of concrete is understood as slow plastic deformation caused by continuous external factors. Changes occurring in the structure of concrete are however not discussed.

“They say we're a rights‐respecting school but nobody knows what that really means”: Children's rights implementation in a Scottish secondary school

open access: yesBritish Educational Research Journal, EarlyView.
Abstract Education has been an enduring feature of international human rights law since the Universal Declaration of Human Rights in 1948 and is the only human right that is compulsory for children. Appearing in all major human rights treaties, including the UN Convention on the Rights of the Child, education is multidimensional and a multiplier of ...

Animal empathy reconsidered: a multidimensional profile account

open access: yesBiological Reviews, EarlyView.
ABSTRACT Empathy is the glue that holds societies together and yet several fundamental questions about empathy persist. What is empathy (the definitional question)? Is it uniquely human and, if not, which nonhuman animals possess empathy (the distribution question)? Which type or quality of empathy is realized in different species (the quality question)

Efficient Approximation Method for Concrete Creep Compliance Function

open access: yesYuanzineng kexue jishu
For concrete, the strain tends to grow when the stress is kept at a constant level. This phenomenon is usually referred to as creep. Creep is an important physical property of concrete.

The Evolution and Integration of ESG Reporting: A Framework for Sustainable Business Accountability

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT This study examines how multinational corporations incorporate Environmental, Social, and Governance (ESG) reporting frameworks to foster trust, enhance legitimacy, and move beyond mere symbolic disclosure. A qualitative comparison of Microsoft and Unilever from 2020 to 2023 assesses how both firms integrate leading standards, including GRI ...
