The aim of this study is to explore the timing and method of endovascular intervention for iliac vein compression syndrome (IVCS) with thrombus.Data from 111 patients with IVCS, complicated acute deep vein thrombosis (DVT), or post-thrombotic syndrome sharpener guide (PTS) who underwent endovascular interventions were analyzed retrospectively.Patie
Cluster-randomized, controlled evaluation of a teacher led multi factorial school based back education program for 10 to 12-year old children
Abstract Background The aim of this cluster-randomised, controlled study was to examine whether a teacher-led multifactorial back education programme could improve back pain in pupils, motor skills, back behaviour, and back knowledge over a 10-month period.Methods There were 176 children from two schools, who were cluster-randomised into interventi
Numerical simulation of low pressure die-casting aluminum wheel
The FDM numerical simulation software, ViewCast system, was employed to simulate the low pressure die casting (LPDC) of an aluminum wheel.By analyzing the mold-fi lling and solidifi cation stage of the LPDC process, the distribution of liquid fraction, temperature field and solidification pattern of castings were studied.The potential shrinkage def
