Accurate georeferencing of TLS point clouds with short GNSS observation durations even under challenging measurement conditions
Zimmermann, Florian; Holst, Christoph; Klingbeil, Lasse; Kuhlmann, Heiner (2018-08-29)The accuracy of georeferenced TLS point clouds is directly influenced by site-dependent GNSS effects, deteriorating the accuracy of the ground control point coordinate estimation. Especially under challenging GNSS ... -
Acid-Catalyzed Rearrangements of 3-Aryloxirane-2-Carboxamides: Novel DFT Mechanistic Insights
Qu, Zheng-Wang; Zhu, Hui; Katsyuba, Sergey; Mamedova, Vera L.; Mamedov, Vakhid A.; Grimme, Stefan (2020-07-01)Efficient synthesis of 3-arylquinolin-2(1H)-ones and N-(2-carboxyaryl)-oxalamides from protic acid-catalyzed rearrangements of 3-aryloxirane-2-carboxamides was achieved recently but not well understood. In contrast to the ... -
Activity coefficients of binary methanol alcohol mixtures from cluster weighting
Kirchner, Barbara; Ingenmey, Johannes Carl Maria; Marchelli, Gwydyon (2020-07-23)The hydrogen bond network of different small alcohols is investigated via cluster analysis. Methanol/alcohol mixtures are studied with increasing chain length and branching of the molecule. Those changes can play an important ... -
Additive prognostic impact of the cerebrospinal fluid arginine/ornithine ratio to established clinical scores in aneurysmal subarachnoid hemorrhage
Weller, Johannes; Lampmann, Tim; Asoglu, Harun; Schneider, Matthias; Ehrentraut, Stefan Felix; Lehmann, Felix; Güresir, Erdem; Dorn, Franziska; Petzold, Gabor; Vatter, Hartmut; Zimmermann, Julian (2023-04-14)Cerebrospinal fluid (CSF) metabolites are increasingly recognized as prognostic factors in aneurysmal subarachnoid hemorrhage (SAH). The CSF arginine/ ornithine ratio (Arg/Orn) was shown to predict cerebral vasospasms ... -
Aiming at self-calibration of terrestrial laser scanners using only one single object and one single scan
Holst, Christoph; Kuhlmann, Heiner (2014-12-05)When using terrestrial laser scanners for high quality analyses, calibrating the laser scanner is crucial due to unavoidable misconstruction of the instrument leading to systematic errors. Consequently, the development of ... -
Also doch ein Dogma?: Fragen zum Verbindlichkeitsanspruch der Lehre über die Unmöglichkeit der Priesterweihe für Frauen aus kanonistischer Perspektive. Eine Nachlese
Lüdecke, Norbert (2000)Papst Johannes Paul II. hat in seinem Schreiben „Ordinatio sacerdotalis“ (1994) die katholische Lehre über die Unmöglichkeit der Priesterweihe für Frauen als „endgültig festzuhalten“ bezeichnet. Der Beitrag geht der Frage ... -
“El amor al arte necesita fondos para que funcione”: Dinámica Artístico-Económica entre los Productores de Eventos en la Escena Musical Electrónica de Posadas, Misiones, Argentina
Fank Ríos, Ricardo Aníbal (2023)Based on an empirical investigation of the “electronic music scene” of the capital city of a peripheral province in Argentina, I try to contribute to an anthropological definition of the “event producer” as an economic ... -
Assessing the quality of life of patients with metastatic castration-resistant prostate cancer with bone metastases receiving [223Ra]RaCl2 therapy
Sraieb, Miriam; Hirmas, Nader; Conrad, Rupert; Marinova, Milka; Essler, Markus; Herrmann, Ken; Ahmadzadehfar, Hojjat (2020-08-19)[<sup>223</sup>Ra]RaCl<sub>2</sub> dichloride treatment in patients with metastatic castration-resistant prostate cancer (mCRPC) is associated with improved overall survival (OS) and a delay in the time to the first ... -
Die Auferweckung Jesu – oder: Woran glauben Christen?: Die urchristliche Osterbotschaft im Kontext zeitgenössischer Vorstellungen
Ebner, Martin (2009)Was ist eigentlich mit „Auferweckung Jesu“ gemeint? Der Beitrag legt die kulturell verankerten Vorstellungen frei und versucht, das im 1. Jahrhundert für jedermann Plausible an dieser Vorstellung vom Besonderen der Aussage ... -
Der Ausschluss des Bonum Coniugum: Ein Ehenichtigkeitsgrund mit Startschwierigkeiten
Lüdecke, Norbert (1995)Das II. Vatikanische Konzil wollte das katholische Eheverständnis erweitern, die Fixierung auf eine fortpflanzungszentrierte Sexualität überwinden und der personal-partnerschaftlichen Dimension der ehelichen Beziehung einen ... -
Automatic optimization of height network configurations for detection of surface deformations
Holst, Christoph; Eling, Christian; Kuhlmann, Heiner (2013-05-18)Levellings are performed to observe height changes of different epochs at discrete surveying points. A reliable estimation of surface deformations by a bivariate polynomial needs a sufficient configuration of the underlying ... -
Avocado-Toast and Drug Cartels: Superfood Production and its consumption in Germany
Tuitjer, Friederike (2023)In recent years many Latin-American foods have become popular globally as “superfoods”. This article analyses the popular discourse in Germany (ca. 2015-2019) and its ambiguities around one of them: Avocado. On the one ... -
Beyond the history of ethnographic collections: A complex approach to the Cora objects gathered by Konrad Theodor Preuss in view of a restitution process
Valdovinos, Margarita (2022)Nowadays, anthropology museums debate between keeping or restituting objects. Through the study of the Cora ethnographic collection obtained by Konrad Theodor Preuss in Mexico (1906), today preserved in the Ethnologisches ... -
Biased and unbiased estimates based on laser scans of surfaces with unknown deformations
Holst, Christoph; Artz, Thomas; Kuhlmann, Heiner (2014-10-02)The estimates based on laser scans of surfaces with unknown deformations are biased and not reproducible when changing the scanning geometry. While the existence of a bias is only disadvantageous at some applications, ... -
Calibration of Terrestrial Laser Scanners: Kalibrierung terrestrischer Laserscanner
Holst, Christoph; Neuner, Hans; Wieser, Andreas; Wunderlich, Thomas; Kuhlmann, Heiner (2016)The calibration of a laser scanner is necessary to reduce systematic errors in the acquired point cloud.
