,Effective stability in Hamiltonian systems in the light of Nekhoroshev’s theorem,r exponentially large times. The applications to the restricted three body problem and to a statistical model of a diatomic gas of identical molecules are illustrated, with the aim of giving good estimates for the size of the stability region and for the dependence on the number of degrees of freedo

,Singular solutions of the cubic Schrödinger equation,esented. It is shown that in three dimensions, the solutions have locally a self-similar form with a blow-up rate (.. - .).. In two dimensions, the self-similarity is weakly broken and the blow up rate is found to be ..

,Real lattices modelled by the nonlinear Schrödinger equation and its generalizations,icroscopic spin waves. Using the multiple scale technique of reductive perturbation we show that the original discrete equations of motion can be reduced to a Nonlinear Schrödinger equation with complex coefficients for the first system and two coupled Nonlinear Schrödinger equations for the second

t gain widespread popularity because many urologists believed the operation was technically difficult and was associated with significant intraoperative hemorrhage and postoperative impotence and incontinence. Over the past 15 years, an anatomical approach to radical retropubic prostatectomy has bee

At the same time, similar advanceshave been made in the clinical arena which have improved the diagnosisand treatment of urologic cancers. .This volume attempts to summarize those advances which most impact usas

Piotr Bileries [1]. On the horizon are new therapeutic techniques incorporating our understanding about the molecular biology of cancer. Notions of gene therapy are already becoming reality, indicating the rapid advance in this area. At present, early detection and knowledge about the clinical and biologic sig
