Crisis y creación. Las ambivalentes relaciones germano-españolas en la producción cinematográfica de la primera mitad del siglo veinte
2016
Politisch-soziale Krisenzeiten tragen in besonderem Maße zur Entstehung und Festigung von bestimmten Auto- und Heterostereotypen bei. Diese schlüssige Behauptung kann man anhand der Analyse der verschiedenen politischen Phasen Spaniens im Laufe seiner Geschichte und ihrer Auswirkung auf das erzeugte Fremdenbild nachvollziehen. Das durch den spanischen Unabhängigkeitskrieg (1808-1814) verbreitete stereotypisierte Gedankengut der Romantik wurde in der ersten Hälfte des zwanzigsten Jahrhunderts zu einem Instrument propagandistischer Manipulation, das den Vorbildcharakter des spanischen Alliierten hervorheben sollte. Dieser politische Kunstgriff verfolgte die ideologische Sympathie für das nati…
Hyaluronan‐coated poly(propylene imine) dendrimers as biomimetic nanocarriers of doxorubicin
2022
A coating technology based on low molecular weight hyaluronic acid (HA) and ferulic acid (FA) was applied to the coating of low generation poly(propylene imine) dendrimers through a biocompatible hexa(ethylene glycol) spacer. The ensuing HA-FA-HEG-PPID dendrimeric materials showed interesting loading capability (between 7.65% and 9.08%) regarding anticancer agent doxorubicin, and their interactions with the drug appeared to hamper the drug release in the physiological environment. Thus, the stable nanostructured loaded delivery systems were able to internalize into cells expressing the HA receptor CD44 and to demonstrate high cytotoxicity comparable to that shown by equivalent amounts of fr…
Nano-graphite cold cathodes for electric solar wind sail
2015
The nanographite (NG) films consisting of tiny graphite crystallites (nanowalls) are produced by carbon condensation from methane–hydrogen gas mixture activated by a direct current discharge. High aspect ratio and structural features of the NG crystallites provides efficient field electron emission (FE). Applicability and performance of the NG films in an electron gun (E-gun) of a solar wind thruster system with an electric sail (E-sail) is tested. The long-term tests are demonstrated suitability of E-gun assembly with the NG cathodes for the real space missions. The results of the tests are analyzed and physical mechanisms of the cathode aging and practical methods for improvement performa…
Bright Visible Luminescence in Silica Nanoparticles
2011
International audience; We demonstrate that a porous film of silica nanoparticles emits a bright visible luminescence associated with defects stabilized by oxygen chemisorption at oxygen deficient center sites. Time-resolved spectra excited by a tunable laser allow us to distinguish the luminescence at 1.99 eV, characteristic of the nonbridging oxygen hole center (NBOHC) (Si-O)3 Si-O*, and a fast and a slow emission: the first (lifetime τ ≈ 25 ns) is peaked at 2.27 eV with an excitation spectrum centered at 5.5 eV; the second (τ ≈ 7.5 μs) is peaked at 2.41 eV and is excited around 3.2 and 5.2 eV. Reaction in an air atmosphere leads to the disappearance of the NBOHC luminescence and of the …
"Media and Society 2022": Proceedings of Scientific Papers
2023
The proceedings represent the collection of reports in two sections of the media and communication science of 80th International Scientific Conference of the University of Latvia. The first section was organized under the auspices of the research project “Risks to Democracy Caused by Disinformation and Conspiracy: Reviewing the Latvian Experience” (lzp-2019/1-0278). This project is implemented with the support of the Fundamental and Applied Project Programme by Latvian Council of Science. The focus of the section was the analysis of current and past information processes, the spread of disinformation, communication ethics, as well as the role of social networks in the spread of information …
Film noir un neo noir komunicētā vēstījuma izmaiņas
2022
Bakalaura darba tēma ir “Film noir un neo noir komunicētā vēstījuma izmaiņas”. Pētījuma mērķis ir uzzināt, kādus vēstījumus nodeva film noir žanra filmas žanra „ziedu laikos” un kādus vēstījumus nodod jaunākas neo noir žanra filmas. Pētījuma teorētisko daļu veido apskats par kino valodu, tās nozīmi un ietekmi, kino valodas elementiem, kā arī film noir teorija, kurā apskatītas film noir iezīmes un stilistika, amerikāņu film noir un neo noir. Tāpat teorijā aprakstīta semiotika un naratīvs. Pētījums veikts, balstoties kvalitatīvās pētījuma metodēs - semiotiskajā analīzē (tiek apskatīti filmu vizuālie elementi) un naratīva analīzē (tiek apskatīta naratīva attīstība, tematika, centrālie notikumi…
"Leggere" e valutare la fiaba cinematografica
2008
Per rintracciare parallelismi e sinergie tra la narrazione filmica e la narrazione letteraria occorre, da un lato, analizzare strumenti, modalità e codici, dall'altro lato, accertare elementi di continuità tra i due modi diversi di raccontare e di rappresentare la realtà, per mettere in evidenza quanto sia importante favorire l'integrazione di diversi tipi di linguaggio. Ci si è proposti, in prospettiva esplorativa, di identificare modalità e livelli di analisi di opere narrative di genere fiabesco trasposte in films. Per stimolare in alunni di scuola primaria il piacere di ricreare e manipolare il prodotto filmico, abbiamo ipotizzato un piano di intervento didattico che consentisse loro la…
Study of Intumescent Coatings Growth for Fire Retardant Systems in Naval Applications: Experimental Test and Mathematical Model
2022
Onboard ships, fire is one of the most dangerous events that can occur. For both military and commercial ships, fire risks are the most worrying; for this reason they have an important impact on the design of the vessel. The intumescent coatings react when heated or in contact with a living flame, and a multi-layered insulating structure grows up, protecting the underlying structure. In this concern, the aim of the paper is to evaluate the intumescent capacity of different composite coatings coupling synergistically modeling and experimental tests. In particular, the experiments have been carried out on a new paint formulation, developed by Colorificio Atria S.r.l., in which the active comp…

Activation of Stainless Steel 316L Anode for Anion Exchange Membrane Water Electrolysis
2023
The increased emphasis on renewable energy has resulted in a surge of R&D efforts into hydrogen and battery research. The intensive electrochemical environment surrounding the anodic oxygen evolution reaction (OER) has plagued both the activity and stability of the catalytic layer, substrate and porous transport layer, ultimately affecting both these industries. Herein, we report the benefits of potential cycling (PC) a 316L stainless steel felt porous transport layer (PTL) for use in anion exchange membrane water electrolysis. The PC increased surface roughness and created a CrFe5Ni2-OxHy layer through the oxidation of iron as shown by SEM, EDS, XPS, XRD and Raman spectroscopy. Post-PC tes…
