Zur Rolle von EDA-Komplexen bei kationischen Polymerisationen. VI[1]. Wechselwirkung von Halogenidionen mit organischen aπ-Elektronenacceptoren

The Role of Donor-Acceptor Complexes in Cationic Polymerisations. The Interaction of Halide Ions with Organic aπ-Acceptors The anions of salts of the type Kat⁺X⁻ (Kat⁺  Li⁺, Na⁺, Et₄N⁺; X⁻  Cl⁻, Br⁻, I⁻) form donor-acceptor complexes with organic a π-acceptors. The long-wave charge-transfer absorption show a bathochrome shift with higher periodic numbers of X⁻ and increasing electron affinity of the acceptors Acc. Strong acceptors form radical ions very rapidly with X  I and slowly with X  Br. Cl. The interactions in the system Kat⁺X⁻ → Acc are influenced by solvents in a very complex way. As acceptors they interact preferably with the halide ion X⁻ and, hence, reduce its donicity for the competing acceptor Acc. As donors they change the dissociation of the ion pair Kat⁺X⁻ by solvation of the cation Kat⁺ and influence in that indirect way also the donicity of X⁻ for the acceptor Acc.     

Manipulation of mental models of anatomy in interventional radiology and its consequences for design of human–computer interaction

Interventional radiology procedures require extensive cognitive processing from the physician. A set of these cognitive functions are aimed to be replaced by technology in order to reduce the cognitive load. However, limited knowledge is available regarding mental processes in interventional radiology. This research focuses on identifying mental model–related processes, in particular during percutaneous procedures, useful to improve image guidance during interventions. Ethnographic studies and a prototype-based study were conducted in order to perform a task analysis and to identify working strategies and cognitive processes. Data were compared to theories from visual imagery. The results indicate a high level of complexity of mental model construction and manipulation, in particular when mentally comparing mental model knowledge with radiology images on screen (e.g., to steer a needle correctly). Regarding current interface support, most difficult is the interpretation and selection of oblique views. New interface principles are needed to bring cognitive demands within reasonable human range, and also accompanying cognitive work strategies should be developed.
