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 ...

CYCLIC STRENGTHS OF CLAY AND SAND BY STRAIN RATE CONTROLLED CYCLIC TRIAXIAL TEST
Doboku Gakkai Ronbunshu, 1995 本研究は, 土の載荷速度依存性に着目して, 飽和粘土を主対象に定ひずみ速度繰返し三軸圧縮試験を行い, 従来の応力制御式による繰返し三軸試験結果と比較検討を行ったものである. また, ゆるい飽和砂とまさ土についても同様の検討を行った. その結果, 定ひずみ速度繰返し三軸試験による実験結果は, 特に粘土やひずみ軟化挙動を起こすような緩い砂, あるいは破砕性土であるまさ土などにおいて応力制御試験によるよりも安定した挙動となることが明らかとなった. さらに, 定ひずみ速度繰返し試験により, 粘土の繰返し強度特性におよぼすひずみ速度の影響について調べた.

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.

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.
