Schütz, Vadim (2022-08-26)This study revealed the impact of 2-benzoxazolinone (BOA), gramine, and quercetin on the microbiota in the bulk soil (Cologne agricultural soil) and investigated direct interactions of the plant secondary metabolites and ... -
The impact of sedimentation and climate variability on the hydrological status of Lake Hawassa, South Ethiopia
Belete, Mulugeta Dadi (2013-12-16)Lake Hawassa is a topographically closed lake in the Central Main Ethiopian Rift Valley. The water level of this lake has been rising significantly with an average rate of 4.9 cm/year over the study period (1970-2010). The ... -
The Impact of Sensor Characteristics and Data Availability on Remote Sensing Based Change Detection
Thonfeld, Frank (2014-12-04)Land cover and land use change are among the major drivers of global change. In a time of mounting challenges for sustainable living on our planet any research benefits from interdisciplinary collaborations to gain an ... -
Impact of the lack of cross-presenting dendritic cells on the generation of inflammatory immune responses in experimental Plasmodium berghei ANKA infection and therapeutic possibilities to limit excessive brain inflammation with doxycycline
Küpper, Janina Melanie (2017-07-21)Malaria is a vector-transmitted disease caused by unicellular parasites of the <em>Plasmodium</em> species and resulted in over 400,000 deaths in 2015, most of them in African children below the age of five. <em>Plasmodium</em> ... -
The impact of the spectral dimension of hyperspectral datasets on plant disease detection
Mewes, Thorsten (2011-04-04)Precision Agriculture as an information based approach requires explicit spatial information about the within field heterogeneities for site-specific applications. Thus, the usage of cost-intensive agrochemicals and the ... -
The impact of tides and mass transfer on the evolution of metal-poor massive binary stars
Marchant Campos, Pablo (2018-05-24)Stars more massive than 10Msun , although few in number compared to objects like our sun, play a very large role in the evolution of the universe. Through strong winds and supernovae they enrich the interstellar medium ... -
Impairment of larval development and a sex-ratio distortion in Litomosoides sigmodontis caused by Wolbachia-depleted microfilariae and localization of a filarial nematode phosphate permease up-regulated during Wolbachia depletion
Arumugam, Sridhar (2009-04-07)The thesis investigates the endosymbiosis between <i>Wolbachia </i>bacteria and their host filarial nematodes. The rodent filaria <i>Litomosoides sigmodontis</i> harbour <i>Wolbachia </i>endosymbionts and the pattern of ... -
Implementation and characterisation of click-SELEX targeting the chemokine CXCL9, for the development of a POC device for renal allograft rejection
Siegl, Julia (2021-11-04)Renal allograft rejection is a serious medicinal condition, as appr. 25 % of the allografts are rejected. This medical disorder will lead to death of the patient if not treated early. Currently the gold standard to diagnose ... -
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 ... -
