Am. Chem. Soc., 2010, 132, 1831]. Using models of SAMs of increasing complexity (dimer, linear N-mers, and two-dimensionally arranged N-mers) and density functional theory on the (TD-) B3LYP/6-31G* level, we determine optical absorption spectra, the nature and magnitude of excitonic couplings, and the corresponding spectral shifts. It is found that at inter-monomer distances of about 20 angstrom and above, TD-B3LYP excitation frequencies (and signal intensities) can be well described by the frequently used point-dipole approximation. Further, calculated blue shifts in optical absorption spectra account for the experimental observations made for azobenzene/gold SAMs, and hint to the fact that they can indeed be responsible for reduced switching probability in densely packed self-assembled structures.}, language = {en} } @phdthesis{Urieta2011, author = {Urieta, Kristin}, title = {Kinder in schwierigen {\"U}bergangssituationen vom Elementar- zum Prim{\"a}rbereich : eine biografieanalytische Studie}, publisher = {Curach Bh{\´a}n Publ}, address = {Berlin}, isbn = {978-3-942002-01-1}, pages = {235 S.}, year = {2011}, language = {de} } @phdthesis{Unterlass2011, author = {Unterlass, Miriam Margarethe}, title = {From monomer salts and their tectonic crystals to aromatic polyimides : development of neoteric synthesis routes}, address = {Potsdam}, pages = {147 S.}, year = {2011}, language = {en} } @phdthesis{Ulrich2011, author = {Ulrich, Mathias}, title = {Permafrost landform studies on Earth : Implications for periglacial landscape evolution and habitability on Mars}, address = {Potsdam}, pages = {VIII, 160 S.}, year = {2011}, language = {en} } @misc{Ulmer2011, author = {Ulmer, Martin}, title = {Stefan Lang, Ausgrenzung und Koexistenz : Judenpolitik und j{\"u}disches Leben in W{\"u}rttemberg und im ‚Land zu Schwaben' (1492-1650). - (Schriften zur s{\"u}dwestdeutschen Landeskunde ; 63) / [rezensiert von] Martin Ulmer}, series = {PaRDeS : Zeitschrift der Vereinigung f{\"u}r J{\"u}dische Studien e.V.}, journal = {PaRDeS : Zeitschrift der Vereinigung f{\"u}r J{\"u}dische Studien e.V.}, number = {17}, issn = {1614-6492}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus-53474}, pages = {258 -- 260}, year = {2011}, abstract = {rezensiertes Werk: Lang, Stefan: Ausgrenzung und Koexistenz : Judenpolitik und j{\"u}disches Leben in W{\"u}rttemberg und im ‚Land zu Schwaben' (1492-1650). - Ostfildern : Thorbecke Verlag, 2008. - 432 S.. - (Schriften zur s{\"u}dwestdeutschen Landeskunde ; 63) ISBN 978-3-799-55263-9}, language = {de} } @article{UflackerKowarkZeier2011, author = {Uflacker, Matthias and Kowark, Thomas and Zeier, Alexander}, title = {An instrument for real-time design interaction capture}, isbn = {978-3-642-13756-3}, year = {2011}, language = {en} } @article{Uffelmann2011, author = {Uffelmann, Dirk}, title = {Die Mobilisierung subalternen Sprechens}, series = {Mobilisierte Kulturen}, journal = {Mobilisierte Kulturen}, number = {1}, issn = {2192-3019}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus-57454}, pages = {377 -- 392}, year = {2011}, language = {de} } @misc{Toennies2011, author = {T{\"o}nnies, Sibylle}, title = {Neumann, F., Behemoth, Struktur und Praxis des Nationalsozialismus 1933 - 1944; Frankfurt am Main, Fischer, 2004}, isbn = {978-3-941880-21-4}, year = {2011}, language = {de} } @article{Toennies2011, author = {T{\"o}nnies, Sibylle}, title = {Ganz oder gar nicht!}, series = {WeltTrends-Papiere}, journal = {WeltTrends-Papiere}, number = {16}, publisher = {Universit{\"a}tsverlag Potsdam}, address = {Potsdam}, issn = {1864-0656}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus-63313}, pages = {71 -- 76}, year = {2011}, abstract = {Inhalt: Der Nomos der Erde ; Die Moralisierung des V{\"o}lkerrechts ; Weltgesetz ohne Weltexekutive ; „Police Bombing"}, language = {de} } @article{Toennies2011, author = {T{\"o}nnies, Sibylle}, title = {Von allem ein bisschen, keine Bewegung?}, series = {WeltTrends-Papiere}, journal = {WeltTrends-Papiere}, number = {16}, publisher = {Universit{\"a}tsverlag Potsdam}, address = {Potsdam}, issn = {1864-0656}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus-63374}, pages = {87 -- 89}, year = {2011}, language = {de} } @phdthesis{Taeger2011, author = {T{\"a}ger, Philipp}, title = {Der Schutz von Menschenrechten im internationalen Investionsrecht : unter besondere Beachtung der Rechte und Pflichten des Exportstaates}, series = {Studien zum internationalen Wirtschaftsrecht}, volume = {4}, journal = {Studien zum internationalen Wirtschaftsrecht}, publisher = {Nomos}, address = {Baden-Baden}, isbn = {978-3-8329-6731-4}, pages = {356 S.}, year = {2011}, language = {de} } @article{TurukinaPikovskij2011, author = {Turukina, L.

Here, non-optimized (chloroform cast) and nearly optimized (solvent-annealed o-dichlorobenzene cast) P3HT:PCBM blend films treated over a range of annealing temperatures are studied via optical and photovoltaic device measurements. Parameters related to the P3HT aggregate morphology in the blend are obtained through a recently established analytical model developed by F. C. Spano for the absorption of weakly interacting H-aggregates. Thermally induced changes are related to the glass transition range of the blend. In the chloroform prepared devices, the improvement in device efficiency upon annealing within the glass transition range can be attributed to the growth of P3HT aggregates, an overall increase in the percentage of chain crystallinity, and a concurrent increase in the hole mobilities. Films treated above the glass transition range show an increase in efficiency and fill factor not only associated with the change in chain crystallinity, but also with a decrease in the energetic disorder. On the other hand, the properties of the P3HT phase in the solvent-annealed o-dichlorobenzene cast blends are almost indistinguishable from those of the corresponding pristine P3HT layer and are only weakly affected by thermal annealing. Apparently, slow drying of the blend allows the P3HT chains to crystallize into large domains with low degrees of intra- and interchain disorder. This morphology appears to be most favorable for the efficient generation and extraction of charges.}, language = {en} } @article{TsegayeDeBleserIribarren2011, author = {Tsegaye, Mulugeta Tarekegne and De Bleser, Ria and Iribarren, Carolina}, title = {The effect of literacy on oral language processing implications for aphasia tests}, series = {Clinical linguistics \& phonetics}, volume = {25}, journal = {Clinical linguistics \& phonetics}, number = {6-7}, publisher = {Taylor \& Francis Group}, address = {London}, issn = {0269-9206}, doi = {10.3109/02699206.2011.567348}, pages = {628 -- 639}, year = {2011}, abstract = {Most studies investigating the impact of literacy on oral language processing have shown that literacy provides phonological awareness skills in the processing of oral language.

Aiming at examining the impact of literacy on oral language processing and its implication on aphasia tests, this study tested 12 non-literate and 12 literate individuals with a modified Amharic version of the Bilingual Aphasia Test (Paradis and Amberber, 1991, Bilingual Aphasia Test.

In addition, compared with literate participants, non-literate individuals demonstrated difficulties in the word/sentence-picture matching tasks.

Location: Brandenburg, NE Germany. Methods: The effect of wild ungulate grazing and browsing was studied in three successional stages: (1) Corynephorus canescens-dominated grassland; (2) ruderal tall forb vegetation dominated by Tanacetum vulgare; and (3) Pinus sylvestris-pioneer forest. The study was conducted over 3 yr. In each successional stage, six paired 4 m(2)-monitoring plots of permanently grazed versus ungrazed plots were arranged in three random blocks. Removal of grazing was introduced de novo for the study. In each plot, percentage cover of each plant and lichen species and total cover of woody plants was recorded. Results: Wild ungulates considerably affected successional pathways and species composition in open habitats but this influence became evident in alteration of abundances of only a few species. Grazing effects differed considerably between successional stages: species richness was higher in grazed versus ungrazed ruderal and pioneer forest plots, but not in the Corynephorus sites. Herbivory affected woody plant cover only in the Pioneer forest sites. Although the study period was too short to observe drastic changes in species richness and woody plant cover, notable changes in species composition were still detected in all successional stages. Conclusion: Wild ungulate browsing is a useful tool to inhibit encroachment of woody vegetation and to conserve a species-rich, open landscape.}, language = {en} } @misc{TrollKulkarniWangetal.2011, author = {Troll, K. and Kulkarni, Amit and Wang, W. and Darko, C. and Koumba, A.
