Potential Impact of Increasing Ammonia Concentrations upon Microbial Population Dynamics in Anaerobic Meso- and Thermophilic driven Fermenters
(2020-02-06)Anaerobic digestion is the process of decomposition of organic matter by a microbial consortium in an oxygen-free environment. The produced biogas from this process is composed of methane, carbon dioxide, nitrogen, oxygen, ... -
Potential of the predatory pentatomid <i>Eocanthecona furcellata</i> (Wolff) as a biocontrol agent on American bollworm in cotton in Myanmar
(2008-06-02)The American Cotton Bollworm (Helicoverpa armigera Hübner)(ABW) is one of the most serious pests of cultivated crops, especially in cotton in Myanmar. Insecticide applications to control ... -
Potentiell photochrome brückenkopfsubstituierte Furo[2,3-d]furane
(2002-04-08)Within the scope of this thesis a photochromic system consisting of furo[2,3-d]furans and bis-quinonemethides was investigated. In the literature the known compounds of this system are ... -
Power-Linked Evaluation of State Forest Organizations
(2021-06-24)Globally, state forest organizations have a wide scope of tasks. They play a central role in managing state-owned forestlands. In addition, they are responsible for implementing forest law on both private and state-owned ... -
Pr$_{1-x}$Ca$_x$MnO$_x$ for Catalytic Water Splitting - Optical Properties and In Situ ETEM Investigations
(2015-09-17)In this thesis, Ca-doped PrMnO$_3$ (PCMO) is evaluated as a catalyst for (photo)electrochemical water oxidation. The investigations are focused on elementary steps of the overall process. First, the optical absorption in ... -
Practical approaches to macromolecular X-ray structure determination
(2011-11-21)The X-ray structure determination of macromolecules is unsurpassed in precision and detail. However, such structures cannot be derived directly from X-ray diffraction data. Phases and a ... -
Prädiktion von Therapieerfolg und Verlauf psychiatrischer Komorbidität bei prognostisch benachteiligten Alkoholkranken
(2005-02-16)This thesis comprises two articles which are concerned with the prediction of therapy outcome and course of psychiatric comorbidity in chronic multimorbid addicts.Article 1Objective: The ... -
Prädiktoren erfolgreicher Therapieverläufe.
(2021-12-20)In the context of different research approaches, a large number of studies have investigated what conditions successful psychotherapy outcomes. The resulting evidence provides the basis for improving psychotherapeutic ... -
Präparation und röntgenkristallographische Untersuchungen an archaebakteriellen Box C/D sRNPs und einer neuartigen Glukosyltransferase aus Thermotoga maritima MSB8
(2005-10-18)A variety of posttranscriptional nucleotide modifications in ribosomal ribonucleic acids (RNAs) are directed by nucleolar RNAs (snoRNAs). The two major classes involved in these modifications ... -
Prebiotic Synthesis of Inorganic Pyrophosphate (PPi) Driven by a Geochemical Redox Reaction
(2021-10-21)In all extant organisms adenosine triphosphate (ATP) is the energy carrier and transmitter of free energy from exergonic to endergonic processes. Since ATP is a complex molecule, it was unlikely available on prebiotic ... -
Precise Nanoengineering of Polymer Functionalized Nanomaterials with Silica as Coating and Templating Tools
(2022-05-10)The construction of a well-defined hybrid nanostructure becomes possible if functional polymer meets inorganic nanomaterials in a well-designed way. To fully control the structure of the nanohybrid and create the synergy ... -
Precision Measurements of the Top Quark Pair Production Cross Section in the Single Lepton Channel with the ATLAS Experiment
(2012-05-10)Two precision measurements of the top quark pair production cross section in the lepton+jets channel are accomplished using data taken by the ATLAS experiment at the Large Hadron Collider at CERN. The data corresponds to ... -
