An equivalent macro-element constituted by a set of six trusses, two for each transverse, longitudinal and diagonal direction, is introduced. The equivalent trusses, whose stiffness is calculated by fully modeled vaults of different geometry, mechanical properties and boundary conditions, simulate the vault in both global analysis and local analysis, such as kinematic or rocking approaches. A parametric study was carried out to investigate the influence of geometrical characteristics and mechanical features on the equivalent stiffness values. The method was numerically validated by performing modal and transient analysis on a three naves-church in the elastic range. Vibration modes and displacement time-histories were compared showing satisfying agreement between the complete and the simplified models. This procedure is particularly useful in engineering practice because it allows to assess, in a simplified way, the effectiveness of strengthening interventions for reducing horizontal relative displacements between vault supports.}, language = {en} } @article{GieseKirschZiegler2006, author = {Giese, S. and Kirsch, Ansgar and Ziegler, M.}, title = {Numerische Untersuchung von Schervorg{\"a}ngen mit der Diskrete-Partikel-Methode}, series = {Bauingenieur : die richtungsweisende Zeitschrift im Bauingenieurswesen ; offizielle Zeitschrift der VDI-Gesellschaft Bautechnik}, volume = {Bd. 81}, journal = {Bauingenieur : die richtungsweisende Zeitschrift im Bauingenieurswesen ; offizielle Zeitschrift der VDI-Gesellschaft Bautechnik}, number = {H. 5}, issn = {0005-6650}, pages = {232 -- 239}, year = {2006}, language = {de} } @article{GielenWolfBerndtetal.1979, author = {Gielen, Hans-G{\"u}nther and Wolf, G{\"u}nter and Berndt, Heinz and Zahn, Helmut}, title = {Synthese der Fragmente A1-8, A9-15 und A16-21 der Schafinsulin-A-Kette unter Verwendung des S-tert-Butylmercaptorestes als Thiolschutzgruppe}, series = {Hoppe-Seyler's Zeitschrift f{\"u}r physiologische Chemie}, volume = {360}, journal = {Hoppe-Seyler's Zeitschrift f{\"u}r physiologische Chemie}, number = {2}, issn = {1437-4315}, doi = {10.1515/bchm2.1979.360.2.1535}, pages = {1535 -- 1548}, year = {1979}, language = {de} } @article{GhoschBaierSchuetzetal.2016, author = {Ghosch, S. and Baier, M. and Sch{\"u}tz, J. and Schneider, Felix and Scherer, Ulrich W.}, title = {Analysis of electronic autoradiographs by mathematical post-processing}, series = {Radiation Effects and Defects in Solids: Incorporating plasma science and plasma technology}, volume = {171}, journal = {Radiation Effects and Defects in Solids: Incorporating plasma science and plasma technology}, number = {1-2}, publisher = {Taylor \& Francis}, address = {London}, issn = {1029-4953}, doi = {10.1080/10420150.2016.1155587}, pages = {161 -- 172}, year = {2016}, abstract = {Autoradiography is a well-established method of nuclear imaging. When different radionuclides are present simultaneously, additional processing is needed to distinguish distributions of radionuclides. In this work, a method is presented where aluminium absorbers of different thickness are used to produce images with different cut-off energies. By subtracting images pixel-by-pixel one can generate images representing certain ranges of β-particle energies. The method is applied to the measurement of irradiated reactor graphite samples containing several radionuclides to determine the spatial distribution of these radionuclides within pre-defined energy windows. The process was repeated under fixed parameters after thermal treatment of the samples. The greyscale images of the distribution after treatment were subtracted from the corresponding pre-treatment images. Significant changes in the intensity and distribution of radionuclides could be observed in some samples. Due to the thermal treatment parameters the most significant differences were observed in the ³H and ¹⁴C inventory and distribution.}, language = {en} } @article{GermanMikuckiWelchetal.2021, author = {German, Laura and Mikucki, Jill A. and Welch, Susan A. and Welch, Kathleen A. and Lutton, Anthony and Dachwald, Bernd and Kowalski, Julia and Heinen, Dirk and Feldmann, Marco and Francke, Gero and Espe, Clemens and Lyons, W.

This is particularly the case if samples are collected by non-conventional techniques such as those required for aquatic subglacial environments. In this paper we present the first analysis of a subglacial brine from Taylor Valley, (~ 78°S), Antarctica for the trace metals: Ba, Co, Mo, Rb, Sr, V, and U. Samples were collected englacially using an electrothermal melting probe called the IceMole. This probe uses differential heating of a copper head as well as the probe's sidewalls and an ice screw at the melting head to move through glacier ice. Detailed blanks, meltwater, and subglacial brine samples were collected to evaluate the impact of the IceMole and the borehole pump, the melting and collection process, filtration, and storage on the geochemistry of the samples collected by this device. Comparisons between melt water profiles through the glacier ice and blank analysis, with published studies on ice geochemistry, suggest the potential for minor contributions of some species Rb, As, Co, Mn, Ni, NH4+, and NO2-+NO3- from the IceMole. The ability to conduct detailed chemical analyses of subglacial fluids collected with melting probes is critical for the future exploration of the hundreds of deep subglacial lakes in Antarctica.}, language = {en} } @article{GerlingPredel1986, author = {Gerling, Ulrich and Predel, Bruno}, title = {Beitrag zur Frage nach der Assoziatbildung in fl{\"u}ssigen Antimon-Zink-Legierungen}, series = {Zeitschrift f{\"u}r Metallkunde : international journal of materials research and advanced techniques.
