Some Effects of the Cutting Fluid on Cutting Force
各種の組成を有する切削油剤を用いて, 切削油剤の潤滑効果と冷却効果が, 切削抵抗に及ぼす影響を調べた。超硬バイトによる車軸鋼の切削の場合につき, 普通鋼の高温における機械的性質の変化を考慮に入れて考察した。またそれらに関連して, 切削油剤の作用について, 定性的に一般的考察をした。1) 削り速度20m/min~40m/minにおいては, いずれの切削油剤も有効であるが, 中でも, 極圧潤滑性に富むものの方が, 冷却性に富むものより有効である。水だけでも明らかに切削抵抗を軽減する作用はあるが, その変動係数は比較的大きく, 特に, 削り速度20m/minの場合には, 乾切削の場合よりも大きい。2) 削り速度40m/min以上においては, 塩素系添加剤のものは効果を失い, かえって切削抵抗は高くなる ...

Influence of Cutting Interactions on Cutting Force of a Pick
Abstract Various mechanical excavators have been used for rock cutting. The cutting drum of an excavation machine normally consists of a large number of cutting picks. Accurate calculation of cutting force on individual picks is important to machine design and control. In rock cutting, cuts between picks can interact with each other.

Multi-scale simulation of the nano-metric cutting process
Molecular dynamics (MD) simulation and the finite element (FE) method are two popular numerical techniques for the simulation of machining processes. The two methods have their own strengths and limitations.

Clinical Validation of Plasma p‐217tau in Neurological Diseases
ABSTRACT Objective Plasma p‐217tau is a minimally invasive but specific biomarker for diagnosing Alzheimer's disease (AD). However, its disease specificity remains to be clinically evaluated. We validated the reliability of the p‐217tau biomarker in 12 other neurological diseases.

Memory and Resting‐State Connectivity in Acute Transient Global Amnesia: A Case–Control fMRI Study
ABSTRACT Background and Objectives Transient global amnesia (TGA) is a striking model of isolated amnesia. While hippocampal lesions are well described, the network‐level mechanisms and the precise neuropsychological profile remain debated. Our objective was thus to characterize functional and neuropsychological correlates of acute TGA and their ...
