A NUMERICAL MODEL FOR GEOTECHNICAL PROBLEMS INVOLVING PARTIALLY SATURATED SOILS
The paper deals with a numeric model for coupled solid–fluid FE analyses of geotechnical problems involving partially saturated soils. The Barcelona Basic Model serves as a constitutive model for the soil skel...

A Symmetric Coupled Fe-Be Method for Vibrating Structures Interacting with an Acoustic Fluid
In order to take the interactions between the vibrations of an elastic structure and the sound field in the surrounding fluid into account, a standard finite element formulation for the dynamic behavior of ela...

A Comparison of Two Variational Formulations for Rubber-Like Materials
Two different variational formulations for rubber-like materials within the framework of the finite element method are briefly reviewed. The first formulation deals with the constraint of incompressible materi...

Coupling of FE- and BE-Discretizations for 3D-Stress Analysis of Tunnels in Layered Anisotropic Rock
After introducing the method developed for the coupling of finite element (FE) and boundary element (BE) discretizations of subregions of solids, comments on the inadmissibility of symmetrizing the resulting c...

Steady-State Pharmacokinetics of Nisoldipine in Patients with Liver Disease
Seven patients with liver disease (fatty liver, chronic hepatitis, liver cirrhosis) were treated with 5 mg nisoldipine daily for up to 21 days. Trough plasma levels reached 0.22 ± 0.22 ng/ml (range 0.10–0.99 n...

Einfluß des Alters auf die hepatische Elimination von Koffein, Hexobarbital und Lidocain in einem internistischen Patientenkollektiv
The liver, like other organs, undergoes age dependent atrophy. Physiological functions are not critically diminished, whereas oxidative drug metabolism is impaired for many substrates. This may be the reason f...

Absorption of Hexobarbital und Caffeine in Patients with Liver Cirrhosis
Hexobarbital and caffeine elimination is impaired in patients with hepatitis and liver cirrhosis according to the severity of the disease. However, absorption of both substances is not altered in patients with...
