Observation of Crack Propagation in Wood at the Cellular Level Considering the Occurrence of Lathe Checks [PDF]

open access: yes
単板切削において単板に生ずる裏割れは単板の品質に,また単板をエレメントとする合板の品質に大きく影響を及ぼす。裏割れの発生は切削に伴って工具刃先近傍に発生する諸切削応力のうち,主として引張応力に起因することが明らかになっている。単板内での裏割れの発生および成長過程を細胞レベルにおいて検証するべく,小さい試験片(厚さ2.5mm)の曲げ試験を実施した。試験片の引張側に亀裂を事前に施し,負荷に伴う亀裂の伝播を細胞の変形および破壊挙動を観察した。また,二次元切削を実施し,得られた切屑の横断面(木口面 ...

Biopolymer Films From Pitahaya (Hylocereus sp.) Cladodes: Development and Structural Characterization Toward the Valorization of an Underutilized Pruning Residue

open access: yesJournal of Food Processing and Preservation, Volume 2026, Issue 1, 2026.
Biopolymer films (Bfs) were developed from pitahaya (Hylocereus sp.) cladodes, an abundant pruning residue that is currently underutilized due to handling and disposal constraints. In this study, we evaluated the individual and combined effects of glycerol (0–2% w/w), and cassava starch (0%–6% w/w) on film formation and performance using a casting ...

Are checks overused? [PDF]

open access: yes
This study overturns the conclusion of a 1990 study by David Humphrey and Allen Berger, which found that check float is responsible for the popularity of checks despite their high resource cost compared to electronic payment instruments.
