G protein coupled receptors require active Gαq to mobilize Gi-Gβγ-dependent calcium
(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
(2024-05-22)(noch nicht zugänglich / not yet accessible) -
G-quadruplex formation in mouse macrophages changes the immune response to bacterial infection
(2024-01-03)G-quadruplexes (G4s) are stable secondary structures that form in guanine-rich regions of DNA and RNA. Guanines bind via Hoogsteen hydrogen bonding and form G tetrads that stack upon each other and become stabilized by a ... -
G-theory of group rings for finite groups
(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 ... -
G. B. Tiepolo und Bildwitz
(2020-02-19)Die Dissertation widmet sich den komischen und scharfsinnigen Elementen im Werk des venezianischen Malers Giambattista Tiepolo und verbindet sie mit der Rhetorik des barocken concettismo. <br /> Verfolgt werden dabei zwei ... -
Gain Calibration of the Upgraded ALICE TPC
(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 ... -
A gain with a drain?: Evidence from rural Mexico on the new economics of the brain drain
(2005-10)Evidence is presented in support of the “brain gain” view that the likelihood of migrating to a destination wherein the returns to human capital (schooling) are high creates incentives to acquire human capital in migrant-sending ... -
Gains of regional cooperation: Environmental problems and solutions
(2004-01)Cooperation between the states of the Caucasus and Central Asia is paramount in solving the region’s environmental problems. Given the acute socio-economic difficulties they face, their slow progress is understandable. ... -
Galactic massive star forming regions near and far: a (sub)millimeter study of the Orion Molecular Cloud 1 and W49A
(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
(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
(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 ... -
Die Galerie Alexanders VII. im Quirinalspalast in Rom: Studien zur Malerei, Ausstattungspraxis und päpstlicher Repräsentation im 17. Jahrhundert
(2021-11-05)Unter den bedeutenden Raumausstattungen mit Monumentalmalereien im 17. Jahrhundert in Rom kommt in der kunsthistorischen Forschung bisher vor allem zwei Werken Pietro da Cortonas eine zentrale Rolle zu: Dem Salone im Palazzo ... -
Das Galeriebild im 18. Jahrhundert und Johann Zoffanys ” Tribuna“
(2006)Die Darstellung von Kunst als Gegenstand der Malerei besitzt eine lange Tradition, deren Erforschung bislang vorzugsweise auf die Blütezeit dieses Genres im 17. Jahrhundert beschränkt blieb. Sammlungsräume, Ateliersituationen, ... -
Gallium-68 und Fluor-18 markierte Annexin V-Analoga zur Darstellung vulnerabler Plaques der Koronargefäße mittels PET/CT
(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
(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 ... -
Die Garantenstellung des Betriebsinhabers
(2017-07-03)Die Arbeit befasst sich mit der Frage, ob der Betriebsinhaber wegen Unterlassens nach §13 StGB für Straftaten seiner Untergebenen verantwortlich ist. Ausgehend vom Ingerenzgedanken gelangt sie zu der Lösung, dass der ... -
Garnet Systematics of Subducted Continental Margins
(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
(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
(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
(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 ...
