G protein coupled receptors require active Gαq to mobilize Gi-Gβγ-dependent calcium
Pfeil, Eva Marie (2021-06-23)The mechanisms by which GPCRs drive calcium mobilization in living cells have been a topic of intense research interest for many years. One such mechanism is the paradigmatic Gi-calcium pathway, which describes how Gβγ ... -
G protein-coupled receptors mobilize intracellular calcium via the Gs-βγ-PLCβ module
Brands, Julian Maximilian Heinrich (2024-05-22)(noch nicht zugänglich / not yet accessible) -
G-theory of group rings for finite groups
Semikina, Iuliia (2018-12-13)In this thesis we investigate Quillen's G-theory of group rings mostly focusing on the case of finite groups. We study the Hambleton-Taylor-Williams decomposition conjecture for G-theory of the integral group rings. The ... -
Gain Calibration of the Upgraded ALICE TPC
Hauer, Philip (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 ... -
Galactic massive star forming regions near and far: a (sub)millimeter study of the Orion Molecular Cloud 1 and W49A
Peng, Tzu-Cheng (2010-09-10)Massive stars play an important role in shaping the structure of galaxies due to the large energy output during their lifetime. However, because of the short evolutionary time scales, the large extinction toward their birth ... -
Galaxies in Milgromian Dynamics
Lüghausen, Fabian (2015-02-04)Since its first formulation in 1983, Milgromian dynamics (also known as modified Newtonian dynamics or MOND) has been very successful in predicting the gravitational potential of galaxies from the distribution of baryons ... -
Galenische Entwicklung eines Insektenrepellents mit verbesserter Haftfestigkeit
Köhler, Jörn (2001)Insektenrepellents wie N,N-Diethyltoluamid (DEET) wirken in der Dampfphase über der Haut, deshalb kann die Wirkdauer durch mechanischen Abrieb der Formulierung von der Haut, Penetration mit anschließender transdermaler ... -
Gallium-68 und Fluor-18 markierte Annexin V-Analoga zur Darstellung vulnerabler Plaques der Koronargefäße mittels PET/CT
Hashlamun, Yasmin (2016-12-22)Die häufigste Ursache von akuten Koronarsyndromen ist die Ruptur einer athero-sklerotischen Plaque der Koronargefäße, wobei ca. 60 - 80% der Infarkte in Bereichen entstehen, die in den Monaten zuvor nicht signifikant ... -
Galois cohomology of Fontaine rings
Lodh, Rémi Shankar (2007)Let $V$ be a complete discrete valuation ring of mixed characteristic. We express the crystalline cohomology of the special fibre of certain smooth affine $V$-schemes $X=Spec(R)$ tensored with an appropriate ring of $p$-adic ... -
Garnet Systematics of Subducted Continental Margins
Sandmann, Sascha (2015-08-05)Four case studies were performed on former continental margins and on a continental fragment inside an ophiolitic unit. The studies include Lu-Hf garnet dating, and garnet characterization by its chemical zoning. Lu zoning ... -
Garten- und Feldgemüsebau am mittleren Niederrhein
Pley, Herbert (1958)Am mittleren Niederrhein, vor den Toren von Düsseldorf und Neuß, erstreckt sich ein Gemüseanbaugebiet, das bisher wenig untersucht und bekannt ist. Dies mag daran liegen, daß es Nahversorgungsgebiet für die benachbarten ... -
Gas Around Active Galactic Nuclei and New Phase Calibration Strategies for High-Frequency VLBI
Middelberg, Enno (2004)We have a project to measure magnetic fields in the obscuring tori of AGNs. We observed five free-free absorbed jets in radio galaxies with polarimetric VLBI at 15 GHz to determine Faraday rotation measures. Surprisingly, ... -
Gas Electron Multipliers: Development of large area GEMS and spherical GEMS
Duarte Pinto, Serge (2012-01-06)Gaseous radiation detectors have been a crucial part of high-energy physics instrumentation since the 1960s, when the first multiwire proportional counters were built. In the 1990s the first micropattern gas detectors ... -
Gas matters: The Molecular and Atomic Gas Budget in Nearby Galaxies from Centers to Outskirts
Eibensteiner, Cosima (2023-12-18)Hydrogen is the most fundamental component of the baryonic universe, and its various phases have played a key role in its evolution from the Big Bang to the present day. To probe and study these phases of hydrogen in the ... -
A gateway to new physics: direct measurement of the top Yukawa coupling to the Higgs boson
Bruscino, Nello (2017-08-23)The top quark has the largest Yukawa coupling in the Standard Model, is the main contribution to the Higgs mass $m_H$ corrections and defines the evolution of the Higgs effective potential with the energy, together with ... -
Gating of the Hv1 proton channel
Schladt, Till Moritz (2022-03-28)Hv1 is a voltage-gated proton channel, which is involved in the regulation of the intracellular pH (pHi) in immune cells. Among the voltage-gated ion channels, Hv1 is unique because it lacks a classical pore domain and its ... -
Gelfand pairs
Yakimova, Oksana (2005)Let K be a compact subgroup of a real Lie group G. The homogeneous space G/K is called <i>commutative</i> or the pair (G, K) is called a <i>Gelfand pair</i> if the algebra of G-invariant differential operators on G/K is ... -
A GEM based Time Projection Chamber with pixel readout
Brezina, Christoph (2013-09-04)The large number of measured track points and the low material budget make a Time Projection Chamber (TPC) the ideal tracking device for particle flow optimized experiments. A highly segmented readout scheme, based on GEMs ... -
Geminale Rekombinationsdynamik solvatisierter Elektronen in flüssigem und überkritischem Wasser
Kratz, Stephan (2013-07-18)Die geminale Rekombinationsdynamik hydratisierter Elektronen wurde in der Vergangenheit immer wieder intensiv und unter verschiedensten Bedingungen untersucht. Dies lag nicht nur daran, dass diese Untersuchungen Einblick ... -
