p53 activity during adenovirus infection
(2010-06-24)Adenovirus is a small DNA tumour virus that has been extensively studied, leading to fundamental discoveries in molecular biology of mammalian cells. In particular, adenovirus oncoproteins ... -
PAC-Lernen zur Insolvenzvorhersage und Hotspot-Identifikation
(2008-07-22)Methods of machine learning are a very powerful tool in bioinformatics. Due to their versatility they also proof useful in different fields of application. In case of supervised learning, ... -
Pair production of Higgs bosons in the final state with bottom quarks and τ leptons in the ATLAS experiment: Search results using LHC Run 2 data and prospect studies at the HL-LHC
(2021-03-30)After the discovery of the Higgs boson, the ultimate test of the electroweak symmetry breaking and the Standard Model (SM) of particle physics is to establish evidence of Higgs boson self-coupling, which can be achieved ... -
Palaeoecological Evidence of Ecosystem Dynamics in Sumatra, Indonesia. Case Studies of Tropical Submountains and Mangroves
(2019-07-03)The mountain and mangrove ecosystems are an important component of Sumatra’s landscape. These highly diverse ecosystems provide numerous ecological services as well as socio-economic function, but they are also sensitive ... -
Paläoökologische Interaktionen von Organismen aus Baltischem und Bitterfelder Bernstein
(2020-11-06)Because of the quick fixation and detailed conservation of millions-of-years-old arthropods, other small animals and plant parts, amber is very suitable for the conservation of ancient behaviours and interactions. In this ... -
Paläoökologische und geochemische Studien auf Schwamm-Mikroinkrustrierer- Gemeinschaften ausgewählter Cipit Kalke aus der St. Cassian Formation (Unterkarn, Obertrias) von der Dolomiten, Nordostitalien
(2010-12-23)The Lower Carnian St. Cassian Formation (Dolomites, NE Italy) is well known for its very diverse and exceptionally well-preserved fauna. It dates from Middle to Late Triassic and comprises ... -
Paläoproterozoisches Krustenwachstum (2.0-1.8 Ga) am Beispiel der Västervik-Region in SE-Schweden und dem Kamanjab Inlier in NW-Namibia
(2013-02-04)Whole rock geochemical analyses using major and trace elements in combination with the Sm-Nd, Rb-Sr, K-Ar and U-Pb isotope systems as well as studies of P-T conditions on metamorphic rocks from the Västervik-area (SE-Sweden), ... -
Palladium(II)-katalysierte Domino-Reaktionen zur enantioselektiven Synthese von Confluentin, Daurichromen- und Rhododaurichromansäure Untersuchungen zur Synthese von Aglaroxin A
(2011-04-28)This thesis is about Palladium(II) catalysed Domino Reactions for the enantioselective Synthesis of Confluentin, Daurichromenic and Rhododaurichromanic acid. These substances were isolated ... -
Palladium- and Ruthenium-Catalyzed C(sp2)–H and C(sp3)–H Arylations
(2024-06-05)Catalysis is arguably the most impactful area of chemistry for society today, driven by the urgent need for highly efficient and environmentally benign reactions. C−H activation, which allows for the direct introduction ... -
Palladium-Catalyzed Oligocyclizations of Some 2-Bromotetradec-1-ene-7,13-diynes Under Heck Reaction Conditions
(2003-12-16)Synthesis of different substituted 2-bromotetradec-1-ene-7,13-diyne precursors can be easily achieved by using 1,7-octadiyne. The cyclization outcome of these precursors depends on the type ... -
Palladium-katalysierte Domino-Reaktionen zum Aufbau bi- und tricyclischer Systeme
(2001-08-30)Domino-processes between palladium-catalyzed cross-coupling reactions - Heck-reaction and Enyne-Cycloisomerization - followed by Diels-Alder-reactions have been studied. The ... -
