Fenêtres sur couples : trois nouvelles de Sean O'Faolain
2003
In several short stories, Sean O'Faolain ponders over the complexity of love relationships and tries to unveil some of the unconscious motivations underlying them. This essay focuses on three of these short stories, namely "There's a Birdie in the Cage", "Discord" and "An Inside Outside Complex", and shows how, in each of them, the fissures or cracks in love relationships are figuratively represented by an isotopy of windows, the various qualities of which are artfully exploited by O'Faolain (the window as partition between contiguous spaces, as transparent filter, as surface or frame). The position of characters with regard to windows (their framing) and their relations to windows (how the…
Building a political image on Instagram: A study of the personal profile of Santiago Abascal (Vox) in 2018
2020
Due to Instagram’s growing popularity in Spain, politicians have also begun to turn to this social network increasingly more. Accordingly, this paper analyses the visual and textual discourse of 259 posts published throughout 2018 on the personal Instagram profile of Santiago Abascal, the leader of the party Vox. Insofar as he is the Spanish politician with the highest number of followers on Instagram, the aim here is to analyse how he uses this social network in order to identify possible strategies that justify his growing number of followers. In the analysis, special attention was paid to aspects that might have contributed to the (self)presentation of Abascal and the promotion of his pa…
Development and characterisation of polymer composite materials with bio-inspired functions
2018
Promocijas darbs ir izstrādāts disertācijas veidā fizikas nozarē materiālu fizikas apakšnozarē. Pētījums tika veikts LU Materiālu mehānikas institūtā. Darbs saistīts ar aktuālu un jaunu pētījumu virzienu: bioinspirēto funkciju tālāku attīstīšanu slodzi nesošos kompozītos. Tās ir mehānisku triecienu vizuālās indikācijas un polimēru matricas vaskulārās pašdziedināšanas funkcijas. Šīs funkcijas tika nodrošinātas, izveidojot viedus slāņus un iebūvējot tos kompozītā. Pētījumā tika noskaidrotas piemērotās pārbaužu secības, attīstītas kvantitatīvas metodes un mehānisks modelis, lai novērtētu jauno funkciju efektivitāti kompozītos. Ir pierādīta funkciju augstā efektivitāte un spēja uzlabot slodzi n…
Towards essential visual variables in user interface design
2014
This paper focuses on visual variables in user interface design from the user perspective. Visual design of user interfaces is essential to users interacting with different software. The study is conducted with 3E-templates for users to express their impressions by writing and drawing regarding visual website design. The data is analyzed with qualitative content analysis through interpretation framework. The results of this study provide new insights into user-centered visual user interface design. The results indicate which are the most essential visual variables in user interface design and therefore should be emphasized in user-centered design that promotes positive UX and, thus, benefit…
Characterization of the "viable but nonculturable" (VBNC) state in the wine spoilage yeast Brettanomyces.
2012
Although the viable but not culturable (VBNC) state has been studied in detail in bacteria, it has been suggested that maintenance of viability with loss of culturability also exists in eukaryotic cells, such as in the wine spoilage yeast Brettanomyces. To provide conclusive evidence for the existence of a VBNC state in this yeast, we investigated its capacity to become viable and nonculturable after sulfite stress, and its ability to recover culturability after stressor removal. Sulfite addition induced loss of culturability but maintenance of viability. Increasing the medium pH to decrease the concentration of toxic SO(2) allowed yeast cells to become culturable again, thus demonstrating …
A Low-Cost Smartphone Sensor-Based UV Camera for Volcanic SO2 Emission Measurements
2017
Recently, we reported on the development of low-cost ultraviolet (UV) cameras, based on the modification of sensors designed for the smartphone market. These units are built around modified Raspberry Pi cameras (PiCams; ≈USD 25), and usable system sensitivity was demonstrated in the UVA and UVB spectral regions, of relevance to a number of application areas. Here, we report on the first deployment of PiCam devices in one such field: UV remote sensing of sulphur dioxide emissions from volcanoes; such data provide important insights into magmatic processes and are applied in hazard assessments. In particular, we report on field trials on Mt. Etna, where the utility of these devices in quantif…
Decoupled control scheme of grid-connected split-source inverters
2017
Grid-connected power conversion systems for renewable energy sources must fulfill several requirements, e.g., the high efficiency, the reduced cost and complexity, and, quite often, the boost capabilities that is usually achieved using a front-end dc–dc boost converter before the inversion stage, leading to a two-stage architecture. Meanwhile, single-stage power conversion systems, which perform the boosting operation within the inversion one, offer some potential advantages, in terms of reducing the complexity and the volume of the whole system. Among several proposed options, the split-source inverter (SSI) has been recently proposed by Abdelhakim et al. as an alternative option with some…
El consumidor especialmente vulnerable: de la protección class-based a la protección state-based
2022
El presente estudio centra su atención en la regulación, desde un punto de vista sustantivo, de la figura del consumidor especialmente vulnerable y de su protección. El legislador español ha querido dar un paso adelante mediante la introducción de dicha figura en el Texto Refundido de la Ley General para la Defensa de los Consumidores y Usuarios (TRLGDCU). Así, la opción escogida ha sido la de incorporar un concepto dinámico del consumidor vulnerable (protección “state-based”), alejado de la concepción tradicional caracterizada por una perspectiva basada exclusivamente en las características individuales (protección “class-based”), que no consideraba factores externos relativos a la situaci…
