Hyper-impulsive motion on manifolds
No full textHyper-impulsive motion is a branch of control theory applied to
Lagrangian mechanical systems developed in [8]. Suppose that part of system's coordinates are 'controllized' i.e. identified with a control function u that can be discontinuous. Due to the presence of the derivative of u in the dynamic equation, the resulting motion is
discontinuous both in the configurations and momenta in the general case. In this paper we show that the discontinuity in the phase-space trajectory consequent to a jump (a finite discontinuity) of the control can be determined by a parallel transport operation relatively to the dynamic connection introduced by C.M.

Laparoscopic adjustable silicone gastric banding (LAP-BAND): how to avoid complications.
No full textBACKGROUND: The laparoscopic application of LAP-BAND is gaining widespread acceptance as a gastric restrictive procedure. At the same time the reported morbidities (i.e., gastric perforation, stomach and/or band slippage) are cause for some concern.
METHODS: From September 1993 until May 1997, 260 patients underwent LAP-BAND at the Department of Surgery at the University of Padova, Italy.
RESULTS: The mortality rate was zero and the morbidity rate requiring reoperation was 3.4% (stomach slippage, gastric perforation, erosion). In order to avoid complications the key points of the technique are reviewed: (1) reference points for dissection (equator of the balloon, left crus); (2) retrogastric tunnel within the layers of the phrenogastric ligament; (3) embedment of the band; (4) proper outlet calibration; and (5) retention sutures.
CONCLUSIONS: Attention to technical details is of paramount importance for a safe, standardized and effective operation
