✦ Synopsis

This paper is devoted to the study of foundation e!ects on the dynamic characteristics of rotor-bearing systems. The modelling and analysis of rotor-bearing}foundation systems based on the "nite element method are discussed. A substructure procedure which includes the foundation e!ects in the motion equations and the application of the dynamic solver of a commercial package is addressed. The design criteria of the foundation for rotating machinery avoiding resonance and suppressing response have also been emphasized through numerical examples.

## Abstract Exposure to emissions from laser printers during the printing process is commonplace worldwide, both in the home and workplace environment. In the present study, cytotoxic and genotoxic effects of the emission from five low to medium‐throughput laser printers were investigated with resp
