Effect of Double Annealing on the Microstructure and Mechanical Properties of a Medium Manganese Steel

steel research international, EarlyView.
A double intercritical annealing strategy is proposed to tailor the multiphase microstructure and mechanical response of a medium‐Mn steel. The treatment produces an ultrafine mixture of ferrite, martensite and multiple austenite populations with graded thermal and mechanical stability, formed through austenite reversion and controlled retransformation.

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 ...

Evolution of the Damping Ratio Considering Cyclic Confining Pressure Under Intermittent Cyclic Loading

Buildings
The damping ratio is essential to conducting dynamic analysis for underground engineering under traffic loading. Variations in the damping ratio are usually studied using cyclic triaxial tests with continuous cyclic loading; however, intermittent loading

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.

Relationships of Cognitive Function With Subsequent Device‐Measured Physical Activity and Sedentary Time in Healthy Individuals and Those With Bipolar Disorder: Findings From the UK Biobank

Acta Psychiatrica Scandinavica, EarlyView.
ABSTRACT Background In bipolar disorder (BD), physical inactivity and sedentary behaviour are prevalent and have been linked to BD's cognitive symptoms, although the directionality of these links is not clear. This proof‐of‐concept study examined whether cognitive function during mid‐ and later‐life was prospectively related to physical activity and ...
