Flexural performance of concrete‐filled steel tubular beams with wood chip aggregate

Structural Concrete, EarlyView.
Abstract This study investigates the flexural performance of concrete‐filled steel tubular (CFST) beams with partial replacement of aggregates by wood chips (0%–25%) through experimental and numerical analysis. This study is novel in that it experimentally and numerically investigates the flexural behavior of CFST beams with partial replacement of ...

Experimental and design‐oriented research on fiber reinforced concrete segmental tunnel linings: A systematic review

Structural Concrete, EarlyView.
Abstract The use of fiber reinforced concrete (FRC) in precast tunnel segments is among the most established and representative applications of this material. Over the past two decades, numerous tunnel linings were constructed with partial or total substitution of conventional steel reinforcement by fibers, this yielding to quantifiable benefits in ...

Using programmable infusion pump in avian species – a validation methodology in geese

Wildlife Biology, EarlyView.
Wildlife face anthropogenic and natural stressors that affect their physiology and behaviour. The activity of the hypothalamic–pituitary–adrenal axis and glucocorticoid (GC) production is intrinsically linked with energy regulation and environmental stressors.

Environmental supportiveness, physical activity, and sedentary time in children with cerebral palsy

Developmental Medicine &Child Neurology, EarlyView.
Greater environmental supportiveness in home, school, and community settings was associated with reduced sedentary time among children with cerebral palsy, while home environmental supportiveness was related to increased light‐intensity physical activity.

Performance of the Direct Current Electric Potential Difference (DCEPD) Method for Crack Extension Measurement in Fracture Mechanics Specimens Exhibiting Split Delaminations

Fatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT This work investigates the performance of the direct current electric potential difference (DCEPD) method for measuring crack extension (∆a$$ \Delta a $$) during fracture toughness tests of ductile steels exhibiting delaminations perpendicular to the main crack plane, known as splits.

Socio‐Ecological Factors of Physical Activity in Children and Adolescents With Down Syndrome: A Mixed‐Methods Systematic Review

Journal of Intellectual Disability Research, EarlyView.
ABSTRACT Background Children and adolescents with Down syndrome (DS) are at risk of obesity due to a reduced level of physical activity (PA). PA in children and adolescents with DS is a multifaceted phenomenon that includes personal, relationship, community and other social factors.

The Ecology of Human Sleep (EcoSleep) Cohort Study: Protocol for a longitudinal repeated measurement burst design study to assess the relationship between sleep determinants and outcomes under real‐world conditions across time of year

Journal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary The interplay of daily life factors, including mood, physical activity, or light exposure, influences sleep architecture and quality. Laboratory‐based studies often isolate these determinants to establish causality, thereby sacrificing ecological validity.
