Success of minimally invasive salivary gland surgery-Quality of life, prognostic factors.

Objective: Goal of this study was to investigate, whether sialendoscopy in obstructive salivary gland disorders affects patients' oral health-related quality of life compared to healthy individuals, and to determine factors that might influence this relationship.

Study Design: Retrospective observational study.

Setting: University of Kiel, Department of Otorhinolaryngology, Head and Neck Surgery.

Novel Polymeric Thin-Film Composite Membranes for High-Temperature Gas Separations.

Novel selective polymeric thin-film composite membranes (TFCMs) for applications at elevated temperatures were developed. Thin selective layers of the polyimides Matrimid 5218 and 6FDA-6FpDA were cast on a developed polybenzimidazole (PBI) porous support prepared by a phase inversion process. The TFCM properties were investigated with different gases in a wide temperature range, including temperatures up to 270 °C.

Development and Characterization of Defect-Free Matrimid Mixed-Matrix Membranes Containing Activated Carbon Particles for Gas Separation.

In this work, mixed-matrix membranes (MMMs) for gas separation in the form of thick films were prepared via the combination of the polymer Matrimid 5218 and activated carbons (AC). The AC particles had a mean particle size of 1.5 μm and a mean pore diameter of 1.
