Morphological Analysis of Kenyon Cells of the Drosophila Mushroom Bodies
(2017-01-18)Learning and memory is an adaptive behavioral trait that allows animals to make predictions about their environment based on previous experiences. Fruit flies that commonly use olfactory cues to locate food sources or ... -
Morphological and molecular adaptation of Aspergillus niger to simulated spaceflight and Mars-like conditions
(2021-10-18)The International Space Station (ISS) is an indoor-closed environment in Low Earth Orbit (LEO). Outside of the ISS, radiation is the most challenging factor outside. In turn, inside the ISS, spaceflight microgravity is the ... -
Morphological instabilities in drying colloids
(2018-10-15)The crystallization of hard sphere colloidal dispersions show a variation of phase behaviours, as the volume fraction of colloidal dispersions increases, particles transform from a liquid to a crystal state, which two ... -
Morphological variation, proximity to water, comparative venom proteomics and snakebite epidemiology of the medically important Cypriot blunt-nosed viper Macrovipera lebetina lebetina
(2023-09-22)Snakes and humans are in a complex relationship. While snakes are of ecological and economic relevance as rodent predators, thus contributing to food security and public health, venomous species are also of medical importance ... -
Mother-infant relationships in wild Guinea baboons (Papio papio)
(2023-02-16)During infancy, primates are heavily dependent on their mothers for nursing, transport, and thermoregulation, but also benefit from associating with their mothers for protection and social support. Furthermore, the mother ... -
Motivierter Informationsaustausch in Gruppen
(2004-08-12)Previous research in the area of information sampling has demonstrated that group discussion is dominated by information known to all members while information exclusively known to only one ... -
Möglichkeiten des Steuerrechts zur Förderung des ökologischen Landbaus - ein Ko-Instrument für eine effizientere Förderung
(2007-02-07)In the context of partially overstressed financial budgets for the acreage payment support in organic farming a more efficient support scheme seems to be necessary in the future. The political ... -
Multi-dimensional Polarized Radiative Transfer Modeling of Titan's Atmosphere
(2003-07-25)The primary purpose of this thesis work is to develop a multi-dimensional radiative transfer model, which includes polarization, for Titan"s atmosphere and to validate this model. The model ... -
Multi-dimensional radiative transfer in circumstellar disks
(2010-01-14)In this thesis a radiative transfer model for the simulation of protoplanetary disks was developed. As a basis served the general stellar atmosphere package PHOENIX (Hauschildt et al. 1999). ... -
Multi-instrument study of the hourly pulsations in Saturn’s magnetosphere
(2017-10-20)The in-situ exploration of the magnetospheres of Jupiter and Saturn has revealed various pulsed phenomena, some of them being periodic. In Saturn's magnetosphere, several studies have reported pulsations with a periodicity ... -
Multi-Layered Policy Generation and Management in Clouds
(2018-01-25)The long awaited Cloud computing concept is a reality now due to the transformation of computer generations. However, security challenges are most important obstacles for the advancement of this emerging technology. A ... -
Multi-Method Chronometric Constraints on the Thermal, Structural and Morphotectonic Evolution of the Eastern and Western Sierras Pampeanas with Special Emphasis on K-Ar Dating of Fault Gouges
(2013-08-20)The thesis presented here is focused on the in investigation of the thermochronological, structural and morphological evolution of the Eastern and Western Sierras Pampeanas in Argentina between 26°S and 34°S latitude. ... -
Multi-modal Statistics of Local Image Structures and its Applications for Depth Prediction
(2008-02-12)Processing in most artificial vision systems and in the human vision system starts with early vision which involves the extraction of local visual modalities (like optical flow, disparity and contrast transition etc.) ... -
Multi-omics studies of RNA polymerase II transcription regulation by cyclin-dependent kinases
(2024-10-30)Phosphorylation of the C-terminal repeat domain (CTD) of RNA polymerase II (Pol II) plays a central role in the regulation of gene transcription in eukaryotes. In yeast and mammals, the CTD is highly conserved and consists ... -
Multi-parameter assessment of mechano-sensitivity driven differentiation of human mesenchymal stem cells
(2020-12-22)What factors and conditions control stem cell differentiation is currently one of the major questions in biomedical research. What factors ultimately influence the cells’ decision is unclear but it has been shown, that ... -
Multi-wavelength Observations of Coronal Waves and Oscillations in Association with Solar Eruptions
(2011-08-11)This thesis presents an observational study of the relationship between flares and filament eruptions, and associated waves and oscillations in flare loops and ambient corona. A detailed ... -
Multifrequenzanalyse eines Samples röntgen- und optisch selektierter Aktiver Galaktischer Kerne
(2005-02-09)The current knowledge of Active Galaxies (AGN) as well as new observational facts suggest that sophisticated observational techniques are necessary to advance our view on AGN. In this work ... -
Multilagenbasierte Transmissionsoptiken für die Röntgenmikroskopie
(2012-08-23)Microscopy in the x-ray regime (0,001 – 10 nm wavelength) is a well-established method filling the gap between light and electron microscopy. Focusing of x-rays using transmission optics like zone plates, spatial resolutions ... -
