Estimates of the bistable region in metal cutting [PDF]
, 2008 The classical model of regenerative vibration is investigated with new kinds of nonlinear cutting force characteristics. The standard nonlinear characteristics are subjected to a critical review from the nonlinear dynamics viewpoint based on the ...

Behavior of Cutting Heat in High Speed Cutting.
Journal of the Japan Society for Precision Engineering, 1998 (1) 切込みや逃げ面接触長さを変化させることにより, 切屑, 被削材, 工具への切削熱の流入割合を求めることができた.(2) 切削熱の切屑への流入割合は, 切削速度の上昇とともに増加し, 被削材, 工具へは減少していく.(3) 高速切削になるにつれて, 逃げ面での摩擦による発熱は無視できなくなる.

Influence of cutting speed and feed on burr formation
, 2022 S.340-346Current results show that there is no practical, suitible, basic approach for estimating and characterizing burr formation. Especially for high speed cutting, several key issues, such as tool wear, influence the friction, residual workpiece ...

Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Background Chronic micro‐inflammation in patients with end‐stage renal disease (ESRD) is a significant driver of cardiovascular complications and diminished quality of life. While standard hemodialysis (SHD) effectively manages small‐molecule clearance, its ability to remove medium‐to‐large uremic toxins—the primary catalysts of systemic ...

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system
FEBS Letters, EarlyView.Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

FEBS Letters, EarlyView.We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...
