From energy provision to protein synthesis: Tunnelling nanotubes as mediators of intercellular metabolic cooperation in cancer

FEBS Open Bio, EarlyView.
The cytoskeleton‐mediated transport of mitochondria via tunnelling nanotubes restores respiration, increases ATP production, rescues cells from apoptosis, activates the AKT/mTOR signalling pathway, promotes cell migration and invasiveness, contributes to cancer progression and treatment resistance.

Effects of machining parameters, ultrasonic vibrations and cooling conditions on cutting forces and tool wear in meso scale ultrasonic vibrations assisted end-milling (UVAEM) of Ti–6Al–4V under dry, flooded, MQL and cryogenic environments – A statistical analysis

Journal of Materials Research and Technology
Ti–6Al–4V, an alloy of titanium has recently gained focus of research to overcome its machinability challenges. Miniaturization in devices has forced a shift towards micro and meso-scale machining.

Some Effects of the Cutting Fluid on Cutting Force

Journal of the Japan Society of Precision Engineering, 1966
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 ...

KDAC6 alters cell morphology and motility through positive and negative modulation of F‐actin distribution

FEBS Open Bio, EarlyView.
KDAC6 has been associated with cell motility and actin structures, but specific domain contributions are not established. The two catalytic domains have differential effects on motility and F‐actin regulation, affecting cortical F‐actin density, motility, stress fibers, and cell spreading.

A force model for superfinish turning of pure copper with rounded edge tools at low feed rate [PDF]

, 2010
This paper presents a model for force prediction of superfinish turning operation on pure copper. The model is divided in two parts. The first part computes the forces acting on the rake face of the tool.
