High-Performance Cutting of Micro Patterns

Procedia CIRP, 2012
This research report presents an innovative piezo-actuated fast tool servo (FTS) for milling operations introducing the highperformance cutting of micro patterns. The outstanding dynamics of the tool enable a highly dynamic depth of cut variation during the cutting process.

The Coupled Influence of Material and Geometric Parameters on Cutting-Edge Micro-Morphology and Wear Property Degradation

Metals
Cutting-edge wear is inevitable in the cutting process of the knife. Studying the relationship between the performance of the knife and the cutting-edge wear is conducive to optimizing the design of the knife and increasing its service life.

Modelling tooth–prey interactions in sharks: the importance of dynamic testing [PDF]

Royal Society Open Science, 2016
The shape of shark teeth varies among species, but traditional testing protocols have revealed no predictive relationship between shark tooth morphology and performance. We developed a dynamic testing device to quantify cutting performance of teeth.

Dietary Protein Intake and Peritoneal Protein Losses in Peritoneal Dialysis Patients

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Peritoneal dialysis (PD) patients lose protein in their waste dialysate, potentially increasing their risk for malnutrition. We wished to determine whether there was any association between losses and dietary protein intake (DPI). Methods DPI was assessed from 24‐h dietary recall using Nutrics software.

Comparative Evaluation of Hemodiafiltration, Hemoperfusion, and Standard Hemodialysis on Efficacy, Inflammatory Control, Dialysis Adequacy, and Safety in End‐Stage Renal Disease: A Prospective Observational Study

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 ...

Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

FEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

Study on Cutting Mechanism and Cutting Performance of Machining for Curved Surface by Ball End Mill using 3D—CAD

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2008
This paper deals with the cutting mechanism and cutting performance by ball end milling of curved surface. Firstly, the modeling of a cutter and a workpiece with a concave curved surface are carried out using 3D-CAD. Secondly, the chip area is calculated
