Wolfertz, Iris (2015-07-23)Frühe Ausscheidungscluster der AlCu-Legierungen und der AlMgCu-Legierungen werden mit numerischen ab-initio Methoden mit Hilfe des DFT-Programmcodes SIESTA untersucht. Cu-Atome favorisieren innerhalb der AlCu-Legierungen ... -
ABA-Dependent and -Independent Regulation of Tocopherol (Vitamin E) Biosynthesis in Response to Abiotic Stress in Arabidopsis
Kreszies, Victoria (2019-05-15)Abiotic stresses in plants lead to elevated levels of reactive oxygen species that can have detrimental effects on photosystems and thylakoid lipids. To limit damage, plants increase the production of antioxidants such as ... -
Abbildende Spektroskopie erosionsrelevanter Bodenparameter in Agrarökosystemen
Gerighausen, Heike (2013-01-23)Die Vielzahl der Funktionen, die der Boden in einem Ökosystem übernimmt, verleiht ihm einen hohen Stellenwert im Mensch-Umwelt-System. Der Boden landwirtschaftlicher Nutzflächen ist im Besonderen eine elementare Säule der ... -
Abbildung und farbtonbasierte Analyse ausgedehnter neuronaler Strukturen
Heysel, Jana Lisa (2021-08-03)Der Hippocampus ist eine Gehirnregion im mittleren Temporallappen, welcher für die Formung des expliziten Gedächtnisses zuständig ist. Lange Zeit galt der Dentatus Gyrus (DG), eine Region im Hippocampus, als “Eingang“ für ... -
Absorptions- und Emissionsspektroskopie an superkritischem, flüssigem und gasförmigem Xenon im Vakuum-Ultravioletten Spektralbereich
Wahl, Christian (2019-02-05)Seit 120 Jahren ist die Existenz des schwersten stabilen Edelgases, Xenon, bekannt. In dieser Zeit haben eine Vielzahl an Arbeiten mittels Spektroskopie seine Eigenschaften untersucht. Heutzutage findet sich Xenon in ... -
Acceleration of microglial clearance function by small TREM2-activating anionic disaccharides
Nunes de Paiva, Vanessa (2014-07-29)Triggering receptor expressed on myeloid cells-2 (TREM2) is an innate immune receptor, which is expressed on myeloid cells, like microglia inside the central nervous system. TREM2 signals via the adaptor protein DAP12. ... -
Access to and reactions of P-functional tetrathiafulvalene derivatives
Kermanshahian, Shahriar (2023-05-09)This Ph.D. thesis describes the chemistry of the first P-functional tetrathiafulvalenes; the chlorophosphanyl-substituted TTFs were subjected to a reaction with Galliumtrichloride, as a chloride abstraction reagent, to ... -
Accumulation and Clearing of Ions in Circular Electron Accelerators
Sauerland, Dennis (2020-09-02)Modern sychrotron light sources have to provide stable storage for electron beams with high charge densities to make brilliant synchrotron radiation available to users. Since requirements on the brilliance of the radiation ... -
Accurate Ground Penetrating Radar Numerical Modeling for Automatic Detection and Recognition of Antipersonnel Landmines
Gonzalez Huici, Maria Antonia (2013-11-14)Ground penetrating radar (GPR) is a promising non-invasive technology for imaging shallowly buried low-metal or non-metallic antipersonnel (AP) landmines. However, the application of GPR to the landmine problem remains ... -
Acetylcholine mediates protective immune responses against the rodent filarial nematode Litomosoides sigmodontis
Neumann, Anna Lena (2022-02-22)Tropical infectious diseases are caused by parasitic helminths, such as lymphatic filariasis and onchocerciasis (river blindness). Filariae have the ability to modulate the immune response of their host in order to be ... -
Acquisition, Transmission and Rendering of Objects with Optically Complicated Material Appearance
Schwartz, Jens Christopher (2015-12-10)A major goal in computer graphics is the generation of photorealistic images. Nowadays, the degree of realism is often not restricted by the rendering algorithm but instead mainly depends on the quality of the virtual scene ... -
Actin cytoskeleton and endomembrane system dependent cell growth
Voigt, Boris (2008)In plants, membrane recycling processes are involved in every instance of cell volume changes which occur during growth, development and adaptation to the environment. The thesis work described here addresses membrane ... -
Actin Regulatory Proteins in Dendritic Arborisation Neurons of Drosophila
Stürner, Tomke (2019-10-23)Dendrites are highly branched extensions of nerve cells, along which signals are received and propagated to the cell body. The correct morphology of dendrites is essential for the function of the nervous system. The ... -
Action of zona pellucida glycoproteins in mouse and human sperm
