The mechanical behavior of these structures is typically different from those of flat laminated structures due to an alternating lay-up sequence, winding tension and manufacturing induced imperfections. However, design and analysis issues require the same engineering data as used for laminated structures in general. It has therefore become necessary to establish an accompanying quality assurance procedure following the production process to identify the material properties of the manufactured tubes especially for the single layer. Consequently, there are three different approaches of determining the elastic moduli and tensile strengths of a filament wound laminate. Either specimens are resected from a curved tube, from a tube with plane areas or standardized flat specimens are manufactured under deviating production conditions. All approaches entail disadvantages, whether in terms of manufacturing or testing parameters including geometry, lay-up sequence, porosity, fiber tension and load direction. This study presents the discrepancies in the determination of mechanical properties of a filament wound glass-fiber-reinforced polymer tube on curved or cylindrical specimens and flat specimens produced to meet the specifications of international standards. In order to obtain material properties not only in longitudinal but also in transverse direction of the tubes, the so-called split-disk tensile test modeled after ASTM Standard D 2290, is used with tube segments.The procedures of specimen production and preparation are described in detail. Material properties such as the fiber volume and void content of the composite specimens are conducted in order to consider quality and production differences. Finally tensile tests are performed and the results are compared and discussed.}, language = {en} } @article{HoenickaKasparSchmidetal., author = {Hoenicka, Markus and Kaspar, Marcel and Schmid, Christof and Liebold, Andreas and Schrammel, Siegfried}, title = {Contact-free monitoring of vessel graft stiffness - proof of concept as a tool for vascular tissue engineering}, series = {Journal of tissue engineering and regenerative medicine}, volume = {11}, journal = {Journal of tissue engineering and regenerative medicine}, number = {10}, publisher = {Wiley}, doi = {10.1002/term.2186}, pages = {2828 -- 2835}, abstract = {Tissue-engineered vessel grafts have to mimic the biomechanical properties of native blood vessels. Manufacturing processes often condition grafts to adapt them to the target flow conditions. Graft stiffness is influenced by material properties and dimensions and determines graft compliance. This proof-of-concept study evaluated a contact-free method to monitor biomechanical properties without compromising sterility. Forced vibration response analysis was performed on human umbilical vein (HUV) segments mounted in a buffer-filled tubing system. A linear motor and a dynamic signal analyser were used to excite the fluid by white noise (0-200 Hz). Vein responses were read out by laser triangulation and analysed by fast Fourier transformation. Modal analysis was performed by monitoring multiple positions of the vessel surface. As an inverse model of graft stiffening during conditioning, HUV were digested proteolytically, and the course of natural frequencies (NFs) was monitored over 120 min. Human umbilical vein showed up to five modes with NFs in the range of 5-100 Hz. The first natural frequencies of HUV did not alter over time while incubated in buffer (p = 0.555), whereas both collagenase (-35\%, p = 0.0061) and elastase (-45\%, p < 0.001) treatments caused significant decreases of NF within 120 min. Decellularized HUV showed similar results, indicating that changes of the extracellular matrix were responsible for the observed shift in NF. Performing vibration response analysis on vessel grafts is feasible without compromising sterility or integrity of the samples. This technique allows direct measurement of stiffness as an important biomechanical property, obviating the need to monitor surrogate parameters.

Um die {\"o}ffentlichen Verwaltungen zu modernisieren, werden hierbei Managementtechniken aus der privaten Wirtschaft zur strategischen Steuerung an Hochschulen und an anderen {\"o}ffentlichen Verwaltungen {\"u}bernommen. Die Hochschulen werden verst{\"a}rkt als Dienstleister wahrgenommen und st{\"a}rker an ihrem tats{\"a}chlichen Output gemessen. Parallel dazu hat der internationale Wettbewerb zwischen Hochschulen zugenommen. Beide Entwicklungen erfordern von den Hochschulen, effektive Managementstrukturen zu entwickeln, die ihre Qualit{\"a}t und Leistungsf{\"a}higkeit sichern und systematisch weiterentwickeln. Hierbei d{\"u}rfen aber die f{\"u}r den Erfolg der Hochschule essenziellen Faktoren wie Kreativit{\"a}t, Innovation und Diversit{\"a}t nicht eingeschr{\"a}nkt, sondern m{\"u}ssen vielmehr gest{\"a}rkt werden. Zudem weisen Hochschulen mit ihren demokratischen hochschulpolitischen Gremien sowie der grundgesetzlich garantierten Freiheit von Forschung und Lehre besondere Strukturen auf, die sich grunds{\"a}tzlich von denen privatwirtschaftlicher Unternehmen unterscheiden. Viele Aspekte klassischer Managementsysteme und die Prozesse zu deren Einf{\"u}hrung k{\"o}nnen also nicht eins zu eins auf Hochschulen {\"u}bertragen werden. In der DGQ-Arbeitsgruppe 360 "Einf{\"u}hrung von Qualit{\"a}tsmanagement an Hochschulen" haben Experten aus verschiedenen Hochschulen ihre Erfahrungen und ihr Wissen zusammengetragen, wie ein ganzheitliches Qualit{\"a}tsmanagementsystem den besonderen Zielsetzungen und Strukturen von Hochschulen gerecht werden kann. In diesem Praxisbuch zeigen die Autoren Schritt f{\"u}r Schritt, wie ein solches Qualit{\"a}tsmanagementsystem eingef{\"u}hrt und gestaltet werden kann und wie es die Qualit{\"a}t und Leistungsf{\"a}higkeit der Hochschule erh{\"o}hen kann. Dabei wird ein starker Fokus auf die Prozessorientierung und den Einsatz von Verbesserungszyklen gelegt. Die relevanten Standards und Normen werden beschrieben und die wichtigsten Begriffe gekl{\"a}rt. Besonders wertvoll sind aber sicher die vielen Beispiele aus {\"u}ber 20 Hochschulen und die Erl{\"a}uterungen zu typischen Stolpersteinen und wichtigen Erfolgsfaktoren - zum Beispiel die große Bedeutung von Kommunikation und Projektmanagement bei der Einf{\"u}hrung eines Qualit{\"a}tsmanagementsystems. Mit diesem Buch hat die Arbeitsgruppe eine Hilfestellung f{\"u}r Praktiker erarbeitet, die sich in Pr{\"a}sidien, Verwaltungsreferaten und den Fachbereichen der Hochschulen mit dem integrierten Management, der Evaluation von Forschung, Studium und Lehre oder der Qualit{\"a}tssicherung besch{\"a}ftigen.
