Notizen: Abstract PURPOSE: A direct comparison of anal sphincter physiology (muscle performance and anatomy-muscle thickness) has not yet been undertaken but may be of importance in patients with defecation disorders. METHODS: We evaluated 15 healthy volunteers by means of anorectal manometry to determine pressure functions of the internal and external anal sphincter. Transcutaneous electromyography was recorded to assess the electrical activity of the external anal sphincter. Thickness of the anal sphincter muscles was measured sonographically from within the anal canal with dorsal projection using a 7.5-MHz 360° rectal panorama scanner. RESULTS: It was shown that neither is the muscle thickness of the external anal sphincter during rest (6.26±1.02 mm) or during squeezing (7.40±1.39 mm) correlated to its squeeze pressure (138.8±15.2 mmHg), nor is the diameter of the internal anal sphincter (2.09±0.58 mm) correlated to its resting pressure (61.1±15.2 mmHg). Finally, the thicker the internal anal sphincter muscle, the lower the electrical activity of the external anal sphincter during squeezing (r=0.74,P 〈0.001). CONCLUSION: It is concluded that both manometry to assess sphincter function and sonography to determine sphincter morphology are important measures in the evaluation of continence function.

Notizen: A finite element formulation to deal with the flow of metals coupled with thermal effects in presented. The deformation process of the metal is treated using the visco-plastic flow approach and the solution technique for the coupled problem implies a simultaneous solution for velocities and temperatures. Some aspects of the numerical solution of the problem are given and in the last part of the paper some examples of steady-state extrusion and rolling problems showing the applicability of the method are shown.

Notizen: The Pontriagin-Vitt equation governing the mean of the time of first passage of a randomly accelerated particles has been studied extensively by Franklin and Rodemich.1 In their paper is presented the analytic solution for the two-sided barrier problem and solutions by several finite difference procedures.This note demonstrates solution of the problem by a Petrov-Galerkin finite element method using upstream weighting functions,2 shown to give rapidly convergent results. In addition, the equation is generalized to include higher statistical moments, and solutions for the first few ordinary moments are reported.
