[Content validity of a culturally adapted checklist for self-assessment of critical incident reporting system audit teams in a Swiss university hospital].

Background: Critical Incident Reporting Systems (CIRS) support the analysis of critical incidents and foster quality improvement in healthcare. The analysis of CIRS reports by designated CIRS teams enable organizational learning. To maintain a constructive work flow CIRS teams should be able to self-assess their work.

Atomic force microscope: a tool for studying ionophores.

The aim of the investigations was to show the analytical use of an atomic force microscopy (AFM) tip coated with an ion-selective membrane and to show that the ion-selective boundary potential is detectable as a force induced by ion-selective electrostatic interactions, which are more pronounced than double-layer forces. This new technique allows the area-specific ion exchange over boundaries to be displayed with a destruction-free technique by AFM in an aqueous buffer. From experiments with ISEs (ion-selective electrodes), a boundary potential for valinomycin was assumed to be established in close vicinity to a K+-releasing surface.
