PFN4 is Required for Acrosome Biogenesis by Regulating Autophagy through PI3K/AKT/mTOR Pathway <strong>Loss of Profilin3 Impairs Spermiogenesis by Affecting Acrosome Biogenesis, Autophagy, Manchette Development and Mitochondrial Organization</strong> <br> Profilins (PFNs) are key regulatory proteins for the actin ... -
Modellierung des kurzwelligen solaren Strahlungshaushalts im Hochgebirge auf der Basis von digitalen Geländemodellen und Satellitendaten am Beispiel des Hunza-Karakorum / Nordpakistan
(2006)Die vorliegende Arbeit stellt die Entwicklung einer GIS-basierten Methode zur quantitativen Ermittlung landschaftsökologisch bedeutsamer potentieller und annähernd reeller kurzwelliger Strahlungsenergieflüsse in einem ... -
Geometry and derived categories of holomorphic symplectic manifolds
(2022-12-02)In this thesis we study various aspects of hyper-Kähler manifolds and abelian varieties such as their derived categories, sheaves, cycles, and topology. The thesis consists of six parts. <br /> The first part is mostly ... -
Direct lineage conversion enables the generation of rejuvenated donor cells for neurotransplantation
(2022-12-01)With the advent of cell programming, several strategies for disease modeling and cell replacement have become available. While directly converted somatic cell-derived induced neurons largely preserve age-associated traits, ... -
Molecular diversity in early stage high-mass protostars
(2022-11-30)During star formation, the molecular gas undergoes significant chemical evolution with the emergence of dense cores harboring hot cores and hot corinos, rich in complex organic molecules (COMs). The formation pathways, ... -
Topics in the Lp theory for outer measure spaces
(2022-11-30)The theory of L<sup>p</sup> spaces for outer measures, or outer L<sup>p</sup> spaces, was introduced by Do and Thiele. Their main interest was its application to the study of the boundedness properties of some multilinear ... -
Insights into high-temperature mineral reactions of calcium silicate materials revealed in operando by in situ Raman spectroscopy
(2022-11-30)Knowledge of high-temperature calcium silicate materials is becoming increasingly interesting for industry in different ways. On the one hand, their application in the construction, cement, refractory, and ceramics industry ... -
Atoms in the lowest Landau level of a synthetic erbium quantum Hall system
(2022-11-30)This thesis presents results on an experimental realisation of a synthetic Landau like system using ultracold erbium atoms in a two-dimensional quantum Hall ribbon geometry. The scheme used to realise artificial magnetic ... -
Zuni Pueblo und Laguna Pueblo: Ökonomische Entwicklung und kulturelle Perspektiven
(2005)Im Mittelpunkt der Untersuchungen steht die Kultur in Laguna Pueblo und Zuni Pueblo in ihrer jeweiligen Wechselbeziehung zur Ökonomie, sowie eine komparative Analyse der Wirtschaft, ihrer Struktur, Entwicklung und der sie ... -
Verdichtete Siedlungsstrukturen in Sydney: Lösungsansätze für eine nachhaltige Stadtentwicklung
(2005)Die vorliegende Arbeit entstand zwischen 1998 und 2002 als Dissertation am Geographischen Institut der Universität Bonn. Ihr Ziel ist es, verdichtete Siedlungsstrukturen auf ihre Nachhaltigkeit hin zu überprüfen. In der ... -
Regulation of inhibitory synaptic connections and distal neuronal complexity by the Ste20-like kinase Slk
(2022-11-28)Neurons in the brain are typically defined by a characteristic morphology of the dendritic tree. Thereby, they can contact neighboring cells and communicate via excitatory and inhibitory synapses. To allow the establishment ... -
Boden- und Wasserrecht in Shigar, Baltistan: autochthone Institutionen der Ressourcennutzung im Zentralen Karakorum
(2004)Im Mittelpunkt der vorliegenden Studie steht die Analyse von Nutzungsmustern und institutionellen Arrangements im Umgang mit den Ressourcen Boden und Wasser am Beispiel der Talschaft Shigar (Baltistan) im Zentralen Karakorum. ... -
Geomorphometrische Struktur eines mesoskaligen alpinen Geosystems
(2004)Im Zentrum dieser Arbeit steht die Analyse der geomorphometrischen Struktur eines mesoskaligen alpinen Geosystems am Beispiel des Turtmanntals, Wallis, Schweiz. -
Measuring Excitations of a Strongly Interacting Superfluid Fermi Gas
(2022-11-24)This thesis investigates experimentally the superfluid phase of strongly interacting ultracold Fermi gases. The diluteness of the considered gases of neutral atoms ensures that their interaction can be described by a single ... -
Minimisation problems in continuum mechanics and generalised convex hulls
(2022-11-24)The goal of this thesis is the analysis of functionals subject to a differential constraint. These functionals appear in minimisation problems which are connected to problems coming from continuum mechanics. In the ... -
Gain Calibration of the Upgraded ALICE TPC
(2022-11-24)For the upcoming Run 3 of the LHC at CERN, the interaction rate of lead-lead collisions will be increased to 50kHz . Especially for the main detector of the ALICE experiment, the TPC, this is a major challenge, as its ... -
Computation of Mass Spectra Using Quantum Chemical Methods
(2022-11-23)Mass spectrometry (MS) is widely used for the structural elucidation of compounds in a vast variety of scientific research. Unfortunately, many methods that aim to predict mass spectra cannot often elucidate the complete ... -
Alles eine Frage der Logik?: Von automobilen Mobilitätspraktiken und -anforderungen zu künftigen Mobilitätskonzepten – ein transdisziplinärer Ansatz
(2022-11-22)Angesichts aktueller Herausforderungen in Städten, etwa der steigenden Verkehrsnachfrage und der damit einhergehenden Belastung für Mensch und Umwelt, wird die Dringlichkeit einer Reduzierung des motorisierten Individualverkehrs ... -
Vacuum drum drying: a novel technology for enabling formulation principles in the development of oral solid dosage forms
(2022-11-21)The present work demonstrates the applicability of vacuum drum drying (VDD) as novel technology in the development of solid, oral dosage forms for two enabling formulation principles: a) manufacture of amorphous solid ...
