Abstract A finite element model was developed to simulate the tire-rim interface. Elastomers were modeled by nonlinear incompressible elements, whereas plies were simulated by cord-rubber composite elements. Gap elements were used to simulate the opening between tire and rim at zero inflation pressure. This opening closed when the inflation pressure was increased gradually. The predicted distribution of contact pressure at the tire-rim interface agreed very well with the available experimental measurements. Several variations of the tire-rim interference fit were analyzed.

This paper reports the viscosities measurements for the binary system dimethyl sulfoxide + 1,4-dimethylbenzene over the entire range of mole fraction at 298.15, 303.15, 313.15 and 323.15 K and atmospheric pressure. The experimental viscosities were correlated with the equations of Grunberg-Nissan, Katti-Chaudhri, Hind, Soliman and McAllister; the adjustable binary parameters have been obtained. The excess Gibbs energy of activation of viscous flow (G*E) has been calculated from the experimental measurements and the results were fitted to Redlich-Kister polynomial equation. The obtained negative excess Gibbs free energy of activation and negative Grunberg-Nissan interaction parameter are discussed in structural and interactional terms.

This article presents experimental measurements performed in order to connect a neuronal cell culture to an exoprosthesis. The experiments focused on the biosignals� acquisition from the cell culture. A special gold-plated glass plate device was realized and several constructive variants were analyzed. A Olympus microscope with fluorescence and photo system was used. The acquisition of bio signals from the neuron culture is realized and described in the paper. The measurements were made in the sterile environment within the laboratory of Institute of Cellular Biology and Pathology. The measurements have been made for the pair of electrodes 1-1 at the edge of the glass plate.
