Abstract Background Percutaneous trans-splenic portal vein recanalization (PVR) has been reported for facilitation of transjugular intrahepatic portosystemic shunts (TIPS), however has not been applied to patients undergoing direct intrahepatic portosystemic shunt (DIPS).We report the utilization of trans-splenic-PVR with DIPS creation in a patient
The reliability assessment of fatigue life of automotive chassis parts is an important part of automobile safety.The fatigue endurance tests of automotive half-axles were carried out.The three-parameter Weibull distribution model was established according to the fatigue life distribution of samples.Using the right approximation method and the genet
We present a mathematical model, based on a compilation of radiocarbon dates, of the transition to the Neolithic, from about 7000 Shoe Inserts to 4000 BC in Europe.With the arrival of the Neolithic, hunting and food gathering gave way to agriculture and stock breeding in many parts of Europe; pottery-making spread into even broader areas.We use a p
