Abstract Background Several anastomotic techniques have been described when performing an oesophagectomy. Each technique has its own merits and drawbacks. The stapled side to creates a widely patent anastomosis with low stricture rate. Methods This video highlights the adopted developed over last 5 years. There are several key steps that need be adhered to, create reliable, robust reproducible ...

Hypervelocity collisions with space debris (SD, natural meteoroids and man-made artifacts) can significantly affect the performance of spacecraft. Here, I use an adaptivemesh Eulerian hydrodynamic code, Mie-Grüneisen solid-mechanics, and a simple material-failure model, running on a modern PC, to analyze the protection afforded by a nominal two-plate aluminum shield to hypervelocity collisions ...
