Amer Alameri1
1Technische Hochschule Mittelhessen, IBMT - Institute for Biomedical Engineering

Bioreactors play a critical role in cultivating biological cells for various applications, such as pharmaceutical production and tissue engineering. Optimizing the cultivation process requires a deep understanding of the flow characteristics within the bioreactor medium. In this study, ... En savoir plus

3-D Modeling of Stresses and Strains in Accessory Carpal Bone Under Maximum Compressive Loading

Thomas Reuter1, Jennifer Gernhardt2, Christian Rutter1, Christoph Lischer2
1Institut Chemnitzer Maschinen- und Anlagenbau e.V., 09117 Chemnitz, Germany
2Klinik für Pferde Allgemeine Chirurgie und Radiologie Freie Universität Berlin, 14163 Berlin, Germany

When treating fractures of the accessory carpal bones in horses, it is important to understand the forces that implants (screws and plates) must withstand. The etiology of the fracture is not fully understood, but their high incidence during exercise suggests a relation to biomechanical ... En savoir plus
