2Department of Surgery, Vancouver General Hospital and University of British Columbia, Vancouver, BC, V5Z 1M9 Canada. irt-Hogg-Dubé syndrome is a rare autosomal-dominant inherited disorder characterized by the presence of firm facial papules that on biopsy are shown to represent fibrofolliculomas [1–3]. Patients with Birt-HoggDubé syndrome have a high predisposition to malignant renal tumors, w...

Amodel for torsional vibration of slender thin-walled tubes with constrained-layer dampers is developed. Assuming that the deformation obeys the Saint-Venant hypotheses, we develop a model suitable for prediction of the complex stiffness per unit length in closed, thin-walled tubes whose walls consist of laminated elastic and viscoelastic layers, and formulate a boundary-value problem for the w...

We consider a beam whose cross-section is a tubular neighborhood, with thickness scaling with a parameter δε, of a simple curve γ whose length scales with ε. To model a thin-walled beam we assume that δε goes to zero faster than ε, and we measure the rate of convergence by a slenderness parameter s which is the ratio between ε2 and δε. In this Part I of the work we focus on the case where the c...
