BACKGROUND There exists a great variety of liver parenchyma transection techniques. The objective of this research is to develop a new method of liver transection, and to compare it with the traditional ones. METHODS An original gas jet transection method of biological tissues and the apparatus "Pneumojet" to make the method practicable were developed in our institute. Comparison between the ...

This paper studied the rule of micro-hole in electrochemical jet machining (EJM) TC4 alloy and established mathematical model process predicted profile. Considering influence gap time, orthogonal experiment was designed. based on response surface analysis (RSA) method. The results indicate that can improve directivity machining, reducing efficiency, but will cause secondary corrosion abrupt cha...

A three-dimensional numerical model was applied to examine the impact of the Burrard Generating Station cooling water on the circulation patterns and thermal regime in the receiving water of Port Moody Arm. A key aspect of this study involved properly incorporating the submerged cooling water buoyant jet into the 3D model. To overcome the scale and interface barriers between the near-field and ...
