Lubricated Plug Valve DesignClearances and leakage prevention are the chief considerations in plug valves. Many plug valvesare of all metal construction. In these versions, the narrow gap around the plug can allowleakage. If the gap is reduced by sinking [r]

Both laparoscopic and fast-track surgery (FTS) have shown some advantages in colorectal surgery. However, the effectiveness of using both methods together is unclear. We performed this meta-analysis to compare the effects of FTS with those of traditional perioperative care in laparoscopic colorectal[r]
