Influence of surface pores on selective laser melted parts under lubricated contacts: a case study of a hydraulic spool valve

Virtual and Physical Prototyping, 2019
Hydraulic valve spools can be produced with hollow structures using SLM to increase dynamic response. The contact between the valve spool and body is crucial and relates to the performance of a hydraulic valve, which has not been studied.

Intraoperative Collection of Ascitic Fluid With Intra‐ or Postoperative Reinfusion in Ovarian Cancer: Safety and Feasibility of a Roller Pumping Method

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Patients with ovarian cancer often present with massive ascites, leading to significant protein loss during surgical procedures. Although cell‐free concentrated ascites reinfusion therapy (CART) is used in palliative settings to mitigate protein loss, its application in intraoperative settings remains unexplored.
