59. Viability of mesenchymal stem cells during electrospinning
Tissue engineering is a technique by which a live tissue can be re-constructed and one of its main goals is to associate cells with biomaterials. Electrospinning is a technique that facilitates the production of nanofibers and is commonly used to develop fibrous scaffolds to be used in tissue engineering. In the present study, a different approach for cell i

60. Influence of a diagonal pre-drilled hole on hole quality during the reaming process using multiblade tools
The requirements of production engineering for a precision hole are to ensure the required quality as well as minimal production costs. The interactions between machine, tool and the pre-drilled hole result in uncertainties during the final reaming process. For this purpose the reaming process itself and the appearance of process faults were focused in a lar
