Then, the absorption spectrum of the reaction product, NADH, was monitored (maximum peak at 340 nm). The results obtained by the spectrophotometric method were compared with the results obtained by the colourimetry, using pH indicators.

Proceedings of an Advisory Group Meeting held in J{\"u}lich, 21-24 November 1994. - Vienna , 1996. - Seite: 43 - 55 IAEA-TECDOC-920 Abstract: It is shown that the difficulty for probabilistic fracture mechanics (PFM) is the general problem of the high reliability of a small population. There is no way around the problem as yet. Therefore what PFM can contribute to the reliability of steel pressure boundaries is demon­strated with the example of a typical reactor pressure vessel and critically discussed. Although no method is distinguishable that could give exact failure probabilities, PFM has several addi­tional chances. Upper limits for failure probability may be obtained together with trends for design and operating conditions. Further, PFM can identify the most sensitive parameters, improved control of which would increase reliability. Thus PFM should play a vital role in the analysis of steel pressure boundaries despite all shortcomings.}, subject = {Bruchmechanik}, language = {en} } @inproceedings{HellmannsBoehmDilger2006, author = {Hellmanns, Mark and B{\"o}hm, Stefan and Dilger, Klaus}, title = {Progress of the manual application of adhesives}, series = {Proceedings of the 3rd World Congress on Adhesion and Related Phenomena : WCARP-III, October 15 -18, 2006, Beijing, China}, booktitle = {Proceedings of the 3rd World Congress on Adhesion and Related Phenomena : WCARP-III, October 15 -18, 2006, Beijing, China}, publisher = {Beijing Adhesion Society of China}, address = {Beijing}, pages = {275 -- 277}, year = {2006}, language = {en} } @inproceedings{PlatenPoghossianSchoening2006, author = {Platen, J. and Poghossian, Arshak and Sch{\"o}ning, Michael Josef}, title = {Pr{\"a}paration von selbstjustierenden Nanostrukturen mittels Schichtausdehnungstechnik}, series = {Sensoren und Mess-Systeme 2006 : Vortr{\"a}ge der 13.

In this study, a single piezoelectric quartz crystal nanobalance modified with polystyrene was employed to detect benzene, toluene, ethylbenzene and xylene (BTEX compounds). The frequency shift of the QCN sensor was found to be linear against the BTEX compound concentrations in the range about 1-45 mg l-1. The correlation coefficients for benzene, toluene, ethylbenzene, and xylene were 0.991, 0.9977, 0.9946 and 0.9971, respectively. The principal component analysis was also utilized to process the frequency response data of the single piezoelectric crystal at different times, considering to the different adsorption-desorption dynamics of BTEX compounds. Using principal component analysis, it was found that over 90\% of the data variance could still be explained by use of two principal components (PC1 and PC2). Subsequently, the successful identification of benzene and toluene was possible through the principal component analysis of the transient responses of the polystyrene modified QCN sensor. The results showed that the polystyrene-modified QCN had favorable identification and quantification performances for the BTEX compounds.}, subject = {Biosensor}, language = {en} } @inproceedings{Kurz2006, author = {Kurz, Melanie}, title = {Recognition of shape in virtual visualizations}, series = {Proceedings : November 15 - 17, 2006, Technische Universit{\"a}t Darmstadt, Darmstadt, Germany ; PACE, Partners for the advancement of collaborative engineering education}, booktitle = {Proceedings : November 15 - 17, 2006, Technische Universit{\"a}t Darmstadt, Darmstadt, Germany ; PACE, Partners for the advancement of collaborative engineering education}, publisher = {Techn.

The most challenging reference mission concerns the transport of a 1.35-tons chemical lander spacecraft into an 80-RJ circular orbit around Jupiter, which would enable to place a 375 kg lander with 50 kg of scientific instruments on the surface of the icy moon "Europa". Thorough analyses show that the best solution in terms of SEP launch mass times thrusting time would be a two-stage EP module and a triple-junction solar array with concentrators which would be deployed step by step. Mission performance optimizations suggest to propel the spacecraft in the first EP stage by 6 gridded ion thrusters, running at 4.0 kV of beam voltage, which would save launch mass, and in the second stage by 4 thrusters with 1.25 to 1.5 kV of positive high voltage saving thrusting time. In this way, the launch mass of the spacecraft would be kept within 5.3 tons. Without a launcher's C3 and interplanetary gravity assists, Jupiter might be reached within about 4 yrs. The spiraling-down into the parking orbit would need another 1.8 yrs. This "large mission" can be scaled down to a smaller one, e.g., by halving all masses, the solar array power, and the number of thrusters. Due to their reliability, long lifetime and easy control, RIT-22 engines have been chosen for mission analysis. Based on precise tests, the thruster performance has been modeled.}, language = {en} }
