Hygieia model: development of a three-dimensional model for the standardized analysis of infection control protocols.

Aim: Until now, there have been no standardized guidelines for the content of infection control protocols. The aim of this research project is therefore to develop a standardized model for the evaluation and analysis of three dimensions: setting, protection targets, and precautions.

Subject And Methods: Events are part of social life and, as such, have a direct or indirect impact on the physical, mental, and social health of all involved groups (employees, artists, subcontractors, visitors, etc.

Additive manufacturing of collagen scaffolds by three-dimensional plotting of highly viscous dispersions.

Additive manufacturing (AM) allows the free form fabrication of three-dimensional (3D) structures with distinct external geometry, fitting into a patient-specific defect, and defined internal pore architecture. However, fabrication of predesigned collagen scaffolds using AM-based technologies is challenging due to the low viscosity of collagen solutions, gels or dispersions commonly used for scaffold preparation. In the present study, we have developed a straightforward method which is based on 3D plotting of a highly viscous, high density collagen dispersion.
