Anchored but not safe: Rare but serious mechanical complications from peritoneal dialysis catheter suture fixation

UroPrecision, EarlyView.
Abstract Background Peritoneal dialysis (PD) catheter fixation techniques are frequently employed to minimize migration and optimize dialysate flow. While mechanical complications of PD catheters are well recognized, adverse events directly attributable to anchoring sutures are rarely described. We report two patients with end‐stage renal failure (ESRF)

DYNAMICS OF AN UMBILICAL CABLE FOR UNDERGROUND BORE-WELL APPLICATIONS

International Journal of Electronics Signals and Systems, 2012
A general model for an umbilical cable for underground bore-well applications is considered. The response of one-degree-of-freedom, nonlinear system under external excitation forces and the effect of the parameters 􀟱2, β and f on the excited system are investigated.
