In these cases, the loss is not limited to the structure itself, which is valid for usual structures. In the past (Edition 1) this danger was simply taken into account by a special hazard factor, multiplying the existing risk for the structure with a number. Now, in the edition 2, we add to the risk for the structure itself a "second risk" due to the losses outside the structure. The losses outside can be treated independently from what occurs inside. This is a major advantage to analyze the risk for sensitive structures, like chemical plants, nuclear plants, or structures containing explosives, etc. In this paper, the existing procedure given by the European version EN 62305-2 Ed.2 is further developed and applied to a few structures.}, language = {en} } @inproceedings{RosinKubalskiButenweg2014, author = {Rosin, Julia and Kubalski, Thomas and Butenweg, Christoph}, title = {Seismic Design of cylindrical liquid storage tanks}, series = {Seismic design of industrial facilities : proceedings of the International Conference on Seismic Design of Industrial Facilities (SeDIF-Conference) ; [Aachen, 26. - 27.

We concentrate on the elucidation of the influence of target length and recognition sequence position on the sensorial performance. The impedimetric measurements are performed in the presence of the redox system ferri-/ferrocyanide and show an increase in charge transfer resistance upon hybridization of ssDNA to the sensor surface. Investigations on the impedimetric signal stability demonstrate a clear influence of the buffers used during the sensor preparation and the choice of the passivating mercaptoalcanol compound. A stable sensor system has been developed, enabling a reproducible detection of 25mer target DNA in the low nanomolar range. After hybridization, a sensor regeneration can be reached with deionized water by adjustment of effective convection conditions, ensuring a sensor reusability. By investigations of longer targets with overhangs exposed to the solution, we can demonstrate applicability of the impedimetric detection for longer ssDNA. However, a decreasing charge transfer resistance change (ΔRct) is found by extending the overhang. As a strategy to increase the impedance change for longer target strands, the position of the recognition sequence can be designed in a way that a small overhang is exposed to the electrode surface. This is found to result in an increase in the relative Rct change. These results suggest that DNA and consequently negative charge near the electrode possess a larger impact on the impedimetric signal than DNA further away.}, language = {en} } @misc{ReyesOchoa2014, type = {Master Thesis}, author = {Reyes Ochoa, Leonel}, title = {Engineering aspects of a parabolic trough collector field with direct steam generation and an organic rankine cycle}, publisher = {Fachhochschule Aachen}, address = {Aachen}, pages = {X, 72 S.}, year = {2014}, language = {en} } @article{RaueWambachGloeggleretal.2014, author = {Raue, Markus and Wambach, M. and Gl{\"o}ggler, S. and Grefen, Dana and Kaufmann, R. and Abetz, C. and Georgopanos, P. and Handge, U.

The Rankine cycle is heated by solar-heated air and/or by the gas turbine's flue gases. The plant can be operated in solar-only, hybrid parallel or combined cycle-only mode as well as in any intermediate load levels where the solar portion can vary between 0 to 100\%. The simulated plant is based on the configuration of a solar-hybrid power tower project, which is in planning for a site in Northern Algeria. The meteorological data for Barstow-Daggett was taken from the software meteonorm. The solar power tower simulation tool has been developed in the simulation environment MATLAB/Simulink and is validated.}, language = {en} } @article{RatkeMilowLisinskietal.2014, author = {Ratke, Lorenz and Milow, Barbara and Lisinski, Susanne and Hoepfner, Sandra}, title = {On an effect of fine ceramic particles on the structure of aerogels}, series = {Microgravity science and technology}, volume = {26}, journal = {Microgravity science and technology}, publisher = {Springer Nature}, address = {Heidelberg}, issn = {0938-0108 ; 1875-0494}, doi = {10.1007/s12217-014-9380-2}, pages = {103 -- 110}, year = {2014}, language = {en} }
