Isogeometric Analysis uses NURBS representations of the domain for performing numerical simulations. The first part of this paper presents a variational framework for generating NURBS parameterizations of swept volumes. The class of these volumes covers a number of interesting free-form shapes, such as blades of turbines and propellers, ship hulls or wings(More)
Background For industrial pharmaceutical protein production fast growing, high producing and robust cell lines are required. To select more pH shift permissive and fast growing sub-populations, the CHO DP-12 (ATCC clone #1934) cell line, an anti-IL8 antibody producing CHO K1 (DHFR) clone, was continuously subcultured at high viability (>90 %) for more than(More)
Introduction For industrial pharmaceutical protein production fast growing, high producing and robust cell lines are required. To select pH-shift permissive and faster growing sub-populations, the CHO DP-12 cell line was serially subcultured for more than four hundred days in shaker flasks. Initial adaptation to growth in suspension was carried out in(More)
Introduction In recent years measurement of permittivity signal has been increasingly used for online biomass monitoring of cell cultures. Breweries use it as an established method for fermenter inoculation and bioprocess control for instance [1]. In the case of animal cell cultures the correlation between permittivity and viable cell densities determined(More)
Background Today’s biopharmaceutical industry is under increasing pressure considering cost efficient development. Short timeframes rule the progress starting from the generation of producer cell lines to the establishment of a final production process. Hence, the timescale for optimization of cell culture media is small, but on the other hand it contains(More)
Background Hybridoma technology was established in the 2nd half of the 20th century and in the view of current protein production it might seem old-fashioned. Despite, it is commonly used to produce monoclonal antibodies (mAbs) for R & D, clinical diagnostics or medical applications and the demand for mAbs produced by hybridomas is still high. However,(More)
Background State-of-the-art medium and feed development has proven its potential for increasing bioprocess efficiency many times. By the application of such advanced chemically defined and animal component-free formulations, in combination with recent cell lines, the yield of mammalian cell cultures was pushed to the binary gram per liter level. In this(More)
The Marine Data Infrastructure Germany (MDI-DE) is a thematic network of federal and state organizations. It was created mainly to enable the reporting requirements for the European Marine Strategy Framework Directive (MSFD) to be carried out technically and organisationally. From a technical-conceptual point of view, it is a spatial data infrastructure(More)
