Um diese f{\"u}r weitere Aufarbeitungsschritte zug{\"a}nglich zu machen, wird aus der Silage ein Presssaft hergestellt. Die Milchs{\"a}ure wird aus einem Silagepresssaft mittels Extraktion durch ionische Fl{\"u}ssigkeiten isoliert. Dabei wird zum einen eine reine Milchs{\"a}ure hergestellt, die z. B. f{\"u}r die Herstellung von Polymilchs{\"a}ure genutzt werden kann. Zum anderen wird ein weniger aufgereinigter Extrakt gewonnen, der f{\"u}r die fermentative Produktion von L-Lysin und 1,2-Propandiol genutzt werden soll. Im Rahmen des Projekts erfolgt die gentechnische Optimierung von Corynebacterium glutamicum f{\"u}r die Umsetzung von Milchs{\"a}urezu L-Lysin. Die im nach der Pressung verbleibenden Presskuchen enthaltenen Grasfasern bestehen zu einem großen Teil aus Polysacchariden. Diese werden hydrolysiert und die dabei freigesetzten Zucker zu Grundchemikalien wie Ethanol oder Itakons{\"a}ure fermentiert.

With the help of these light patterns the sensor surface of the LAPS device can be read out sequentially in a raster like scheme (scanning LAPS). The DLP approach has several advantages compared to conventional scanning LAPS set-ups, e.g., the spot size, the shape and the intensity of the light pointer can be changed easily and no mechanical movement is necessary, which reduces the size of the set-up and increases the stability and speed of measurement.}, language = {en} } @article{AbouzarPedrazaSchoeningetal.2010, author = {Abouzar, Maryam H. and Pedraza, A.

In those scenarios the dedicated resources execute submitted jobs according to the request of a workflow engine or Grid wide scheduler. This approach has various limitations, particularly if human interactions should be integrated in workflow execution. To support human interactions with the benefit of enabling inter organizational computation and community approaches, this poster paper proposes the idea of a pull-based task distribution strategy. Here, heterogeneous resources, including human interaction, should actively select tasks for execution from a central repository. This leads to special demands regarding security issues like access control. In the established push-based job execution the resources are responsible for granting access to workflows and job initiators. In general this is done by access control lists, where users are explicitly mapped to local accounts according to their policies. In the pull-based approach the resources actively apply for job executions by sending requests to a central task repository. This means that every resource has to be able to authenticate against the repository to be authorized for task execution. In other words the authorization is relocated from the resources to the repository. The poster paper introduces current work regarding to the mentioned security aspects in the pull-based approach within the scope of the project "HiX4AGWS".}, language = {en} } @article{SchollSchubertZieneretal.2010, author = {Scholl, Ingrid and Schubert, Nicole and Ziener, Pascal and Pietrzyk, Uwe}, title = {GPU-basiertes Volumenrendering von multimodalen medizinischen Bilddaten in Echtzeit}, series = {Bildverarbeitung f{\"u}r die Medizin 2010}, journal = {Bildverarbeitung f{\"u}r die Medizin 2010}, publisher = {Springer}, address = {Berlin}, isbn = {978-3-642-11967-5}, pages = {400 -- 404}, year = {2010}, abstract = {Die vorliegende Arbeit zeichnet sich dadurch aus, dass registrierte unsegmentierte Volumina aus multimodalen Bilddatens{\"a}tzen (z.B.
