Feature extraction for improved disruption prediction analysis at JET.

Disruptions are major instabilities and remain one of the main problems in tokomaks. Using Joint European Torus database, a disruption predictor is developed by computational methods including supervised learning techniques. The main objectives of the work are to develop accurate automatic classifiers, to test their performances, and to determine how much in advance of the disruption they can operate with acceptable reliability.

[The laparoscopic treatment of a rare case of intestinal obstruction due to an ectopic pregnancy]. / Trattamento laparoscopico di un raro caso di occlusione intestinale da gravidanza ectopica.

A rare case of intestinal occlusion due to primary abdominal pregnancy is described. Laparoscopy revealed normal appendix and bowel obstruction by adhesion between the last ileal loop and cecum. The adhesion started from a neoformation (diameter 2 cm) localised on the mesenteric side of the ileum, about 30 cm from the ileocecal valve. A resection of the adhesion and dissection of the neoformation were performed. Laparoscopic procedures lasted 30 minutes. Histologic examination of the specimen revealed to be an ectopic pregnancy. The laparoscopic technique permitted to verify the diagnosis and perform the treatment of the abdominal pregnancy in absolute conditions of safety, maintaining the fertility of the patient (actually she is presenting a regular pregnancy).

[Laparoscopy in an abdominal emergency: the diagnosis and therapy in 3 clinical cases of acute abdomen]. / Laparoscopia nell'urgenza addominale: diagnosi e terapia in tre casi clinici di addome acuto.

Authors report three cases of acute abdomen due a probable appendicitis and submit to laparoscopic procedure. In the first case acute abdomen was due to a bowel obstruction secondary to an ectopic pregnancy; in the second case acute appendicitis was associated with a rare congenital malformation (atresia of uterus); in third case acute abdomen was due to a rare case of torsion of accessory spleen in an adult. In all the cases laparoscopy demonstrated the elective procedure in urgency, permitting the diagnosis and the surgical treatment of acute abdomen with the post-operatory advantage of the technique.
