Implementation of a high throughput screening assay to identify and characterize insecticides acting on ion channels
Brockmann, Andreas (2023-11-03)With 800 million people suffering from hunger, new innovative crop protection products are required to ensure food supply and stop hunger. The voltage-sensitive sodium channel (VSSC) was shown to be a safe and effective ... -
Implementation of a kinematic fit of single top-quark production in association with a W boson and its application in a neural-network-based analysis in ATLAS
Loddenkötter, Thomas (2012-09-05)In order to provide discrimination between the <i>Wt</i>-channel signal and its backgrounds for analyses that try to measure single top-quark production in the <i>Wt</i>-channel, a kinematic fit to the lepton+jets decay ... -
Implementation of the local land-use and land-cover change model CLUE-s for Central Benin by using socio-economic and remote sensing data
Orekan, Vincent Oladokoun Agnila (2007)Within the last decades wide areas in West Africa are subjected to serious land-use and land-cover changes (LUCC). The detection of the changes, the understanding of the underlying processes as well as modeling of scenarios ... -
Implementation of the novel high-throughput Fungal Isolation one step Device method FIND and secondary metabolite extraction from the isolate Heydenia cf. alpina
Libor, Benjamin (2021-07-13)Fungi are an important source of bioactive metabolites. The cultivation of source organisms is a crucial step in natural product isolation. With standard isolation methods for fungi it is difficult to isolate rare und ... -
Die Implementierung des Themas Fernerkundung in den Schulunterricht der Sekundarstufe I durch das neue MINT-Wahlpflichtfach "Geographie-Physik": eine Studie zur praktischen Schulfachgestaltung im Differenzierungsbereich der Jahrgangsstufen 8 und 9 an Gymnasien in Nordrhein-Westfalen am Beispiel des Gymnasiums Siegburg Alleestraße
Müller, Christina Maria (2021-10-26)Schülerinnen und Schüler werden in ihrer Alltagswelt seit dem letzten Jahrzehnt immer früher mit Satellitenbildern konfrontiert. Durch den Wetterbericht und die Nachrichtensendung im Fernsehen oder durch virtuelle Globen ... -
The implication of microglial sialic acid-binding immunoglobulin-like lectin-E (Siglec-E) in neuroinflammation
Claude, Janine (2014-03-07)Microglia are the resident immune cells of the central nervous system (CNS). They display a whole set of recognition receptors on their cell surface to sense intact or lesioned cells in the CNS. A subfamily of these receptors ... -
Implication of the TREM2/DAP12 Complex in Microglial-mediated Tissue Homeostasis under Healthy and Pathological Conditions
Bodea, Liviu-Gabriel (2014-03-26)Microglial activation was previously associated with neurodegenerative diseases such as Parkinson’s disease (PD) or Alzheimer’s disease (AD). The prototype of primary microglia neurodegenerative disorder is represented by ... -
The importance of endogenous cannabinoids in stress-related disorders and depression
Jenniches, Imke (2017-02-03)The endogenous cannabinoid system (ECS) is a unique neuromodulatory system, essentially involved in a variety of physiological processes. It consists of the two major endogenous cannabinoids (eCBs), anandamide and 2-AG, ... -
The importance of endogenous opioids in feeding behavior
Ghule, Aishwarya (2018-03-14)Endogenous opioids are involved in a broadly distributed neural network regulating eating behavior. Opioid transmission has long been implicated in controlling hedonic and homeostatic feeding as well as regulating body ... -
Improved Approximation Algorithms for Weighted k-Set Packing
Neuwohner, Meike (2024-01-16)We study the weighted k-Set Packing problem, which is defined as follows: The input consists of a finite collection S of non-empty sets, each of cardinality at most k, as well as a positive weight for each of the sets. The ... -
Improved Cardinality Bounds for Rectangle Packing Representations
Silvanus, Jannik (2019-05-29)Axis-aligned rectangle packings can be characterized by the set of spatial relations that hold for pairs of rectangles (west, south, east, north). A representation of a packing consists of one satisfied spatial relation ... -
Improved techniques for pulsar data analysis
Voraganti Padmanabh, Prajwal (2021-09-29)Pulsars are rapidly rotating, strongly magnetised neutron stars with spin periods ranging from few milliseconds to tens of seconds. They emit beams of electromagnetic radiation that are predominantly detected as periodic ... -
Improvement of hail detection and nowcasting by synergistic combination of information from polarimetric radar, model predictions, and in-situ observations
Schmidt, Mari Luna (2020-10-21)Large hail can pose a major threat to people, infrastructure, and property. While polarimetric radar observations enable us to reliably detect hail, discrimination of hail size and strategies to nowcast and predict hail ... -
Improvements and application of the STatistical Analogue Resampling Scheme STARS
Lutz, Julia (2017-07-03)Basically, there are two approaches to downscale climate simulations from global climate models to a regional scale: dynamical and statistical downscaling. This thesis focuses on a statistical method – the Statistical ... -
Improving solubility and supersaturation of poorly soluble drugs using solid dispersions based on natural polymers and mixtures thereof
