Zum Akademiestreit als eine Stufe auf dem Weg des Künstlers in sich selbst. Carl Hauptmanns "Einhart der Lächler"
2016
W powieści „Einhart der Lächler“ Carl Hauptmann opisuje drogę życiową artysty, która okazuje się poszukiwaniem własnej tożsamości. Carl Hauptmann ubiera swą opowieść w popularną formę powieści edukacyjnej. Droga Einharta prowadzi przez instytucje sztuki, wówczas napiętnowane przez konflikt pomiędzy wykształceniem akademickim artysty a jego kreatywną wolnością. Poniższy tekst koncentruje się na osadzeniu tego napięcia w ramach historycznych. W dalszej części przedstawione zostaną powiązania głównego bohatera z zaprzyjaźnionym z Carlem Hauptmannem malarzem – Otto Muellerem.
TripAdvisor reviews as a teaching tool in the Tourism Spanish Classroom
2021
RESUMEN: Este artículo tiene como objetivo señalar la importancia de incluir y aprovechar en el aula de español con fines profesionales (Efp) los nuevos materiales del ámbito del turismo que han surgido en los últimos años. El trabajo parte del análisis pragmalingüístico de un corpus de elaboración propia de comentarios negativos de TripAdvisor. Después se señalan sus posibilidades didácticas para su implementación en el aula de español del turismo. ABSTRACT: The purpose of this article is to point out the importance of including and taking advantage of the new materials in the field of tourism that have emerged in recent years in the Spanish classroom for professional purposes (Efp).

The Kingdom of Ends and the Ethical Community: On the Intersubjective Dimension of Kant’s Ethics
2019
En este trabajo propongo considerar dos de las objeciones frecuentemente dirigidas a la filosofía moral kantiana: en primer lugar, aquella que cuestiona su presunto carácter individualista; en segundo lugar, aquella objeción que impugna su pretendido formalismo. Atendiendo a este objetivo examinaré, en primer lugar, la noción de reino de los fines, tal como aparece desarrollada en la Fundamentación de la metafísica de las costumbres y, en segundo lugar, la idea de comunidad ética, esbozada en La religión dentro de los límites de la mera razón. A través del análisis de ambas nociones, y de su posible relación o articulación, intentaré señalar que la ética kantiana, lejos de limitarse a la me…
FRCM systems for strengthening masonry structures
2017
Composite materials have been widely used for strengthening weak masonry buildings. Particularly, wrapping with fibre reinforced polymer (FRP) composites has become a common method for strengthening masonry members primarily subjected to compressive static loads or seismic actions. More recently, in an effort to alleviate some drawbacks associated with the use of FRP materials, fibrereinforced cementitious matrix (FRCM) composites have received a lot of interests for external strengthening of historical masonry structures. It is used as an alternative to FRP in situations where these composites have shown some disadvantages or their use is banned. This paper presents a literature review on …
Constant sign and nodal solutions for nonlinear robin equations with locally defined source term
2020
We consider a parametric Robin problem driven by a nonlinear, nonhomogeneous differential operator which includes as special cases the p-Laplacian and the (p,q)-Laplacian. The source term is parametric and only locally defined (that is, in a neighborhood of zero). Using suitable cut-off techniques together with variational tools and comparison principles, we show that for all big values of the parameter, the problem has at least three nontrivial smooth solutions, all with sign information (positive, negative and nodal).
High-Power Multicarrier Generation for RF Breakdown Testing
2017
Testing of satellite components for high RF power breakdown effects, such as multipactor and corona or passive-intermodulation, is a topic of growing interest in the aerospaceindustry. Switching fromthe classical single carrier approach to the more realisticmulticarrier scenario is very challenging from the experimental point of view. Themulticarrier signals, amplifiedby several RF power amplifiers, need to have controlled phase, amplitude, and frequency in each carrier. Fine tuning of the signal generator phases is required in order to compensate the phase drift occurring in the active elements of the test bed. This paper presents an efficient and low-cost technique to generate multicarrie…
Static and dynamic structure of $ZnWO_4$ nanoparticles
2011
Abstract Static and dynamic structure of ZnWO 4 nanoparticles, synthesized by co-precipitation technique, has been studied by temperature dependent x-ray absorption spectroscopy at the Zn K-edge and W L 3 -edge. Complementary experimental techniques, such as x-ray powder diffraction, Raman and photoluminescence spectroscopies, have been used to understand the variation of vibrational, optical, and structural properties of nanoparticles, compared to microcrystalline ZnWO 4 . Our results indicate that the structure of nanoparticles experiences strong relaxation leading to the significant distortions of the WO 6 and ZnO 6 octahedra, being responsible for the changes in optical and vibrational …
X-ray and dielectric characterization of Co doped tetragonal BaTiO3 ceramics
2016
ABSTRACTThe crystal structure modifications of BaTiO3 induced by cobalt doping were studied. The polycrystalline (1 − x)BaTiO3 + xCo2O3 samples, with x ≤ 10 wt.%, were prepared by high temperature sintering conventional method. According to X-ray phase and structural characterization, performed by full-profile Rietveld refinement technique, all synthesized samples showed tetragonal symmetry perovskite structure with minor amount of parasitic phases. Pure single-phase composition has been detected only in the low level of doping BaTiO3. It was indicated that substitution of Co for the Ti sites in the (1 − x)BaTiO3 + xCo2O3 series led to decrease of tetragonality (c/a) of the BaTiO3 perovskit…
Enhancement of the dielectric response through Al-substitution in La1.6Sr0.4NiO4 nickelates
2016
The structures and dielectric properties of La1.6Sr0.4Ni1−xAlxO4 (x = 0, 0.2 and 0.4) ceramics elaborated using the Pechini method were studied for the first time. The same unique tetragonal phase was found in all compounds. The lattice parameters were found using Rietveld refinement. The surface morphology characterization and elemental analysis of these samples were respectively carried out using scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDS). A giant dielectric response was observed in these ceramics, and one dielectric relaxation was found. The substitution of nickel with aluminum results in a colossal dielectric constant value (>106). The dielectric l…
Spectroscopic study of the electric field induced valence change of Fe-defect centers in SrTiO(3)
2011
The electrochemical changes induced by an electric field in Fe-doped SrTiO(3) have been investigated by X-ray absorption spectroscopy (XANES and EXAFS), electron paramagnetic resonance (EPR) and Raman spectroscopy. A detailed study of the Fe dopant in the regions around the anode and cathode reveals new insights into the local structure and valence state of Fe in SrTiO(3) single crystals. The ab initio full multiple-scattering XANES calculations give an evidence of the oxygen vacancy presence in the first coordination shell of iron. Differences in the length and disorder of the Fe-O bonds as extracted from EXAFS are correlated to the unequivocal identification of the defect type by compleme…
