The Journal of the Society of Chemical Industry, Japan, 1965 ポリプロピレンの降伏点強度について,温度,引張速度,分子量,結晶化度等の影響を検討した。その結果,降伏点強度の引張速度に関する分散曲線は,ある温度,引張速度の範囲内でWLF式で表わされる移動係数を用いて重ね合わせられる可能性を認めた。また,分子量の影響はほとんど見られず,結晶化度により大きく影響される。これは結晶化度の増加により非晶部分の変形速度が増加したことに対応する挙動を示し,これについても温度と同様に,結晶化度の異なる各合成曲線を時間軸に対して移動させることにより重ね合わせることができる。

Pediatric Blood &Cancer, EarlyView.ABSTRACT We present two pediatric cases of pediatric low‐grade gliomas (PLGG) with BRAF V600E mutations diagnosed and monitored using cerebrospinal fluid (CSF) liquid biopsy analyzed via digital droplet PCR (ddPCR), without tissue biopsy. Both patients were treated with dabrafenib and trametinib and monitored through clinical assessments, magnetic ...

Simplified method measures changes in tensile yield strength using least number of specimens [PDF]
, 1967 Simplified method determines yield strength due to heat treat, irradiation or mechanical treatment. Each specimen in a group of specimens is tested for yield stress point, subjected to heat treat or irradiation, and retested for new yield stress point ...

Solid-fluid dynamics of yield-stress fluids
, 2014 On the example of two-phase continua experiencing stress induced solid-fluid phase transitions we explore the use of the Euler structure in the formulation of the governing equations.

Stress resultant plasticity for shells revisited [PDF]
, 2012 In this work, we revisit the stress resultant elastoplastic geometrically exact shell finite element formulation that is based on the Ilyushin–Shapiro two-surface yield function with isotropic and kinematic hardening.

Elastoplastic behavior of yield stress fluids [PDF]
Physical Review Fluids, 2019 By means of the incremental elastic modulus for small deformations superimposed on creep and subsequent recovery tests, we follow the structural state of various soft-jammed systems (yield stress fluids) in their solid regime. We demonstrate that the solid state of the material is associated with a persistent elastic network of constant elastic modulus

“Everything flows?”: elastic effects on startup flows of yield-stress fluids
Rheologica Acta, 2017 It is now 30 years since Barnes and Walters published a provocative paper in which they asserted that the yield stress is an experimental artifact. We now know that the situation is far more complicated than understood at the time, and that the mechanics

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Psychological safety (PS) is essential for teamwork, communication, and patient safety in complex healthcare environments. In pediatric oncology, interprofessional collaboration occurs under high emotional and organizational demands. Low PS may increase stress, burnout, and adverse events.
