Study on Cumulative Damage Law of Stainless Steel-Reinforced Concrete Columns under Step Impact Loading

Advances in Materials Science and Engineering, 2019
In this study, an ultrahigh drop hammer impact test system was adopted for multiple horizontal impact tests on stainless steel-reinforced concrete columns and ordinary-reinforced concrete columns with the same longitudinal reinforcement diameter.

Experimental and numerical study on the energy dissipation behavior of carbonyl iron powder/shear-thickening composites under high-energy impact [PDF]

AIP Advances
Shear-thickening materials exhibit rate-dependent mechanical responses. However, their intrinsic physical characteristics and dynamic performance under high-energy impact loading remain insufficiently studied.

Leveraging Big Multitemporal Multisource Satellite Data and Artificial Intelligence for the Detection of Complex and Invisible Features: The Case of Extensive Irrigation Mapping

Archaeological Prospection, EarlyView.
ABSTRACT The detection of buried or obscured archaeological features remains a central challenge in landscape archaeology, particularly in the irrigated floodplains of Mesopotamia where levees and canals formed the basis of complex agrarian systems. This study presents a deep learning–based approach for the large‐scale, automated detection of ancient ...

String Figuring young children's perspectives of quality in English early childhood education and care

British Educational Research Journal, EarlyView.
Abstract Quality in early childhood education and care (ECEC) is a contested concept and has generally been conceptualised by inter‐related indicators such as staff qualifications, educational environment, policy or child‐to‐staff ratios. There has been a more limited emphasis on how young children might perceive and experience quality.

Mechanical Behavior of Unsaturated Soils Subjected to Impact Loading

Shock and Vibration, 2016
This paper presents an experimental study on unsaturated soils. A designed test setup was used and the impact loading was applied with a drop hammer. The experimental results show that the soil properties, including water content, density, void ratio ...

Reception Baseline Assessment and ‘small acts’ of micro‐resistance

British Educational Research Journal, EarlyView.
Abstract In September 2021, following the global COVID‐19 pandemic, the Department for Education introduced a national standardised digital Reception Baseline Assessment (RBA) for all English 4‐year‐old children. We analyse RBA and its associated Quality Monitoring Visits, as a further intensification of the new public management of early years ...

Bourdieu in Aotearoa New Zealand: A systematic review of theoretical applications in educational research, 2000–2025

British Educational Research Journal, EarlyView.
Abstract This article presents the first systematic review of scholarship applying Pierre Bourdieu's theoretical framework in New Zealand educational research, drawing on 30 peer‐reviewed studies published between 2000 and 2025. Following PRISMA guidelines, studies were coded for Bourdieusian concepts applied, depth of theoretical application ...

Investigation of Energy Absorption in Aluminum Foam Sandwich Panels By Drop Hammer Test: Experimental Results

, 2017
The sandwich panel structures with aluminum foam core and metal surfaces have light weight with high performance in dispersing energy. This has led to their widespread use in the absorption of energy. The cell structure of foam core is subjected to plastic deformation in the constant tension level that absorbs a lot of kinetic energy before destruction

Animal empathy reconsidered: a multidimensional profile account

Biological 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)
