Limitation of natural sources, especially of fossil resources, for base material that is currently used to produce polyamides and related composites together with the increasing demand of these products, promotes the search for renewable sources of the base material. Fermentation by genetically engineered bacteria gains increasing interest as one of these possible sources.
Cadaverine is a biogenic amine that can be produced by Corynebacterium glutamicum from the amino acid lysine by heterologous expression of a lysine decarboxylase from Escherichia coli.
Overexpression of the patA and patD genes from Escherichia coli in Corynebacterium glutamicum enables the latter to further metabolize cadaverine to 5 aminovalerate (5AVA), which is a potential base material for the production of nylon 5 and a C5 platform for the synthesis of base materials for other polyamides.
Chemical industry is facing an increasing demand on polyamides and related composites, whereas in contrast the accessibility of base material from fossil sources for their production alleviates. Therefore, in seek for alternative and renewable sources, bacterial fermentation has become into focus in several chemical production areas. The offered invention provides such a source for nylon production and related composites.

Tunable lasers are used in a wide range of applications like profilometry, laser spectroscopy, optical sensors for measuring pressure and temperature and optical coherence tomography (OCT). In many applications, a very rapid tuning, i.e. shifting from one wavelength to another is desired. A powerful concept enabling ultra-high tuning rates is e.g. Fourier Domain Locking (FDML).

Design and method for positive locking torque transmission. Common steel wheels can be combined with modern carbon composite shafts. Chipping process steps become unnecessary due to the integration in the shaft manufacturing process.

The present invention provides a stent remover for open surgery which can be used to safely remove a stent without causing tissue damage. In a first step, at least three wires are threaded through the mesh of one end of the stent. Then, all wire ends are fed through a sleeve and fixed with a crimping device. Afterwards, the wires in the sleeve can easily be introduced into the funnel-shaped tube of the stent remover. By operating the turning knob of the device, a uniform and controllable pulling force is exerted to the wires. In this way, the stent constricts evenly and can easily be removed without serious tissue damage. In addition, stent removal with this novel device shortens the operation time, thereby reducing the potential for unforeseen complications. On behalf of RWTH Aachen University, PROvendis offers access to rights for commercial use as well as the opportunity for further co-development.

In principal all known conventional satellite navigation systems like GPS, Galileo, GLONASS, QZSS and BeiDou are enabling the determination of the position with accuracy on the centimeter-level by help of the carrier phase. However, the carrier signals, upon which the navigation signals are modulated, are typically impaired by various error sources, like ionospheric errors, tropospheric errors, instrumental errors and/or other error sources, leading to a defective determination of the position. The invention enables a precise and reliable relative positioning (relative kinematic positioning – RTK) with centimeter-level accuracy in urban environments as well as a precise attitude determination (heading estimation with 0.25°/m accuracy) with low-cost sensors. Wit the new method the above mentioned errors can be
eliminated reliably.

The invention concerns hybrid carbon fibre composite parts, whose surfaces are trued up by foils, additional surface processes are obsolete.
