Contact problems are frequent in structural analysis. They are characterized by inequality constraints such as non-interpenetration conditions, sign condition on the normal constraints, and an active contact, an area that is a priori unknown. Several approaches exist for solving the non linear equations issued from the finite element discretization of frictionless contact problems. In this work...

OBJECTIVE This study aimed to assess the application of the Betty Neuman systems model to the care of patient/clients with multiple sclerosis. METHODS This clinical study resulted from the application of the nursing process to a patient/client admitted with multiple sclerosis in the neurological ward of a hospital in an urban area of Iran.

We consider a system of ordinary di erential equations consisting of a singularly perturbed scalar di erential equation of second order and a scalar di erential equation of rst or second order and study a Neuman-Cauchy or a Neuman-Dirichlet problem. We assume that the degenerate equation has two intersecting solutions such that the standard theory for systems of Tichonov's type cannot be applie...

Prologue I thank Ground Water and its editor for the privilege of sharing some highlights of my personal and professional lives with colleagues. The story of my childhood, which is a key to understanding who I am, might otherwise have never been told: I owe it to our younger colleagues, my children, and my grandchildren. I urge the reader to explore further the historical events and circumstanc...
