Such surface or liquid phase studies are done with the aim to understand the fundamental mechanisms of DNA radiation damage and to improve cancer radiotherapy. When ionizing radiation is used, abundant secondary electrons are formed during the irradiation process, which are able to attach to the molecular compounds present on the surface. In the present study we experimentally investigate low energy electron attachment to TRIS and methyliminodiacetic acid ( MIDA), an analogue of EDTA, supported by quantum chemical calculations. The most prominent dissociation channel for TRIS is through hydroperoxyl radical formation, whereas the dissociation of MIDA results in the formation of formic and acetic acid. These compounds are well-known to cause DNA modifications, like strand breaks. The present results indicate that buffer compounds may not have an exclusive protecting effect on DNA as suggested previously.}, language = {en} } @misc{AbramowiczArnoldDrorietal.2014, author = {Abramowicz, Isidoro and Arnold, Rafael and Drori, Itamar and Haußig, Hans-Michael and Huber, Jasmina and Katz, Daniel S. and Keßler, Katrin and Kleinecke, Ulrike and Knufinke, Ulrich and Przystawik, Mirko and Nemtsov, Jascha and Rebiger, Bill and Ries, Rotraud and Salzer, Dorothea M. and Schirrmeister, Sebastian and Stellmacher, Martha}, title = {PaRDeS : Zeitschrift der Vereinigung f{\"u}r J{\"u}dische Studien e.V. = 'Ein Gebet ohne Gesang ist wie ein K{\"o}rper ohne Seele.' : Aspekte der synagogalen Musik}, number = {20}, editor = {Denz, Rebekka and Salzer, Dorothea M.}, publisher = {Universit{\"a}tsverlag Potsdam}, address = {Potsdam}, isbn = {978-3-86956-290-2}, issn = {1614-6492}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus-70306}, year = {2014}, abstract = {Die Zeitschrift m{\"o}chte die fruchtbare und facettenreiche Kultur des Judentums sowie seine Ber{\"u}hrungspunkte zur Umwelt in den unterschiedlichen Bereichen dokumentieren.

To this end, we combine county-level data on child care coverage with detailed individual-level information from the German social security records and exploit a set of German reforms leading to a substantial temporal and spatial variation in child care coverage for children under the age of three. We conduct an event study approach that investigates the labor market outcomes of mothers in the years around the birth of their first child. We thereby explore career trajectories, both in terms of quantity and quality of employment. We find that public child care improves maternal labor supply in the years immediately following childbirth. However, the results on quality-related outcomes suggest that the effect of child care provision does not reach far beyond pure employment effects. These results do not change for mothers with different 'career costs of children'.}, language = {en} }
