In this paper, we show how a convex optimization methodology can be used to determine a static solution, representing exit-valve settings in a multi-node reservoir system. A tunedvalve algorithm is used to produce an optimal flow solution and is based on the objective of minimizing overall combined sewer overflow (CSO) reservoir spillage to receiving waters under a combination of dry and wet (s...

This paper evaluated the oil spillage risk in the waters near the island of Changxing in Dalian (China) based on the established risk assessment index. Four wind regimes (windless, northerly wind, westerly wind and southerly wind) were selected as weather conditions for the dynamic prediction of oil drift. If an oil spill occurs near the Koumen (a place near the island of Changxing), the foreca...

Abstract—In this work, startability of the Busemann intake family with weak/strong conical shock, as most efficient intakes, via overboard mass spillage method is theoretically analyzed. Masterix and Candifix codes are used to numerically simulate few models of this type of intake and verify the theoretical results. Portions of the intake corresponding to various flow capture angles are conside...

material hazards are the most important risk in scientific laboratories. in risk assessment processing, the potential impact of assessor personal judgment is the most important issue. this study tried to develop a risk assessment pattern based on failure mode and effect analysis (fmea) and analytical hierarchy process (ahp) logics and empirical data in scientific laboratories. the most importan...

Laparoscopic cholecystectomy is considered the gold standard surgical intervention for the treatment of symptomatic gallstones. Gallbladder perforation (1040%) and stone spillage (6-30%) are the two complications encountered most often during the dissection and removal of the gallbladder in LC. Gallstone spillage was initially considered to be a benign event with no serious squeal. However, the...

V caseosa, the “cheese-like” white cutaneous material covering the skin of newborns, is a very unusual cause of peritonitis. Only 15 cases of this entity have been described. Although spillage of amniotic fluid into the peritoneal cavity is almost inevitable after cesarean section, this spillage is usually insignificant and only rarely does it progress to peritonitis. The exact mechanism for th...

Laparoscopic cholecystectomy (LC) is associated with a significant risk of gallbladder perforation with spillage of bile and stones into the peritoneal cavity. The retrieval of the spilled stones is not always possible by laparoscopic technique. Majority of these cases do not have any problem in future but sometimes the lost stones lead to serious complications. The authors present a case of lo...

spillage of scoleces is a major problem in surgery of hydatid cysts, because each of them may develop into a new cyst if it settles on a suitable site such as the peritoneum. many surgeons believe that scoleces in ruptured hydatid cysts of the liver containing bile are not able to develop new cysts, because bile kills thein. in order to prove this idea, the viability of scoleces in such cysts w...
