New skulls of the basal sauropodomorph Plateosaurus trossingensis from Frick, Switzerland: is there more than one species?
2021
The Triassic basal sauropodomorph Plateosaurus trossingensis is well-known from mass accumulations at the German localities of Trossingen and Halberstadt and the Swiss locality of Frick, and is significant especially regarding its ta-phonomy and proposed developmental plasticity. These implications, however, rely on the assumption that this material derives from a single species, which has been questioned. Here we describe new skull material from Frick including eight complete and six partial skulls, more than doubling the number of known skulls of P. trossingensis. This exceptional sample size allows for gaining a deeper understanding of variability that may occur in a single species. The …
Investigation of insulin resistance in narcoleptic patients: dependent or independent of body mass index?
2011
Alice Engel1,2, Jana Helfrich1, Nina Manderscheid1, Petra B Musholt3, Thomas Forst3, Andreas Pfützner3, Norbert Dahmen1,21Department of Psychiatry, University of Mainz, Germany; 2Fachklinik Katzenelnbogen, Katzenelnbogen, Germany; 3IKFE, Institute for Clinical Research and Development, Mainz, GermanyBackground: Narcolepsy is a severe sleep-wake cycle disorder resulting in most cases from a lack of orexin, the energy balance-regulating hormone. Narcoleptic patients have been reported to suffer from an excess morbidity of Type 2 diabetes, even after correction for their often elevated body mass index.Methods: To explore whether narcolepsy is specifically associated with a propensity …
Prognostic Relevance of CCN3 in Bone Sarcomas
2010
Osteosarcomas and Ewing’s sarcoma (EWS) are aggressive malignant bone tumors. In both cases, prognostic markers are lacking. Presently, only clinical features are widely accepted as prognostic indicators. In this study we assessed the prognostic value of CCN3 (Nov), a matricellular protein that belong to the CCN family of regulatory proteins, whose members were shown to play crucial roles in bone formation. In osteosarcomas, CCN3 expression levels represent a useful tool to early identification of patients with different prognosis. In both osteosarcomas and Ewing’s sarcomas, the expression of a full length CCN3 protein was associated to a worse prognostic and a higher risk to developing met…
Audience experience of commercial videos and feature length films : are they universal or culturally mediated?
2017
Audiovisual contents constitute one of the most common ways of communicating information. However, audiovisual products are difficult to study because they integrate a lot of complex communication and artistic elements. Meaning and emotions are conveyed by combining film elements but also narrative elements, music and other audio aspects, which unfold over time and can be used to impact the audiences. Here, the user experience approach is taken to try to understand the relation between the video’s elements and the emotions produced in the audience. Emotions are understood within an appraisal framework where elements of the audiovisual format and content are integrated in memory with previou…
Los juegos de rol en la educación artística: su aplicación en los museos de arte.
2015
Se trata de una investigación orientada a la práctica educativa, en la que se reflexiona sobre el funcionamiento y la pedagogía ofrecida por los museos de arte y se analiza críticamente, proponiendo un cambio educativo que apueste por la incorporación de los juegos de rol en la práctica docente en el Área de Educación Artística durante las visitas a los museos. Es un estado de la cuestión que busca proponer una práctica educativa innovadora en cuanto a la educación artística y las visitas que tienen lugar en los museos de arte. Es una investigación que toma como datos experiencias que han tenido lugar en museos y centros educativos que han elegido los juegos de rol como medio metodológico p…
Synthesis of Unexpected Dimethyl 2-(4-Chlorophenyl)-2,3-dihydropyrrolo[2,1-a]isoquinoline-1,3-dicarboxylate via Hydrolysis/Cycloaddition/Elimination …
2021
Hydrolysis/[3 + 2] cycloaddition/elimination cascades employed for the synthesis of unexpected tricyclic compound derived from isoquinoline. Reaction of ethylene derivative 1 with the isoquinoline ester iminium ion 2 in alkaline medium (MeOH/NEt3) under reflux for 1 h resulted in the formation of the fused pyrrolo[2,1-a]isoquinoline derivative 3. Its structure was elucidated by X-ray single crystal and other spectrophotometric tools. Hirshfeld calculations for 3 and its crystal structure analysis revealed the importance of the short O…H (19.1%) contacts and the relatively long H…C (17.1%), Cl…H (10.6%) and C…C (6.1%) interactions in the molecular packing. DFT calculations were used to compu…

BIFOCAL PAIRS OF IMAGES FOR LOW-COST SURVEY IN CLOSE RANGE PHOTOGRAMMETRY
2019
Abstract. This paper present a method for close range photogrammetry based on an camera positioning scheme in which two cameras capture an equal portion of an object at the same scale, but have different focal lengths and camera-to-object distances. This scheme is alternative to the stereoscopic scheme and is associated with a system of equations which permits one to calculate first the relief displacement of points on a photograph and then their relief relative to a reference plane. The obtained relief and relief displacement values can be used to produce low-cost orthophotographs by using software for image processing, which doesn’t need to be dedicated, but has to provide measurement and…
UAS BASED TREE SPECIES IDENTIFICATION USING THE NOVEL FPI BASED HYPERSPECTRAL CAMERAS IN VISIBLE, NIR AND SWIR SPECTRAL RANGES
2016
Abstract. Unmanned airborne systems (UAS) based remote sensing offers flexible tool for environmental monitoring. Novel lightweight Fabry-Perot interferometer (FPI) based, frame format, hyperspectral imaging in the spectral range from 400 to 1600 nm was used for identifying different species of trees in a forest area. To the best of the authors’ knowledge, this was the first research where stereoscopic, hyperspectral VIS, NIR, SWIR data is collected for tree species identification using UAS. The first results of the analysis based on fusion of two FPI-based hyperspectral imagers and RGB camera showed that the novel FPI hyperspectral technology provided accurate geometric, radiometric and sp…
HYPERSPECTRAL REFLECTANCE SIGNATURES AND POINT CLOUDS FOR PRECISION AGRICULTURE BY LIGHT WEIGHT UAV IMAGING SYSTEM
2018
Abstract. The objective of this investigation was to study the use of a new type of a low-weight unmanned aerial vehicle (UAV) imaging system in the precision agriculture. The system consists of a novel Fabry-Perot interferometer based hyperspectral camera and a high-resolution small-format consumer camera. The sensors provide stereoscopic imagery in a 2D frame-format and they both weigh less than 500 g. A processing chain was developed for the production of high density point clouds and hyperspectral reflectance image mosaics (reflectance signatures), which are used as inputs in the agricultural application. We demonstrate the use of this new technology in the biomass estimation process, w…
