Mikroinfluenceru autentiskums sociālajā tīklā "Instagram": Betijas Kalējas, Zanes Milzarājas un Māras Slejas gadījumu analīze
2022
Bakalaura darba „Mikroinfluenceru autentiskums sociālajā tīklā "Instagram": Betijas Kalējas, Zanes Milzarājas un Māras Slejas gadījumu analīze” mērķis ir noskaidrot, kāda nozīme mikroinfluenceru sekotājiem ir to autentiskumam, kā arī, kādus līdzekļus influenceri pielieto sevis prezentēšanai un autentiskuma radīšanai sociālajā tīklā "Instagram". Darbs sastāv no četrām galvenajām daļām – teorētiskās, metodoloģiskās, empīriskās un secinājumiem. Darba teorētiskajā daļā tiek apskatīta akadēmiskā literatūra par sociālo tīklu "Instagram" un komunikācijas iespējām tajā, ietekmētājiem jeb influenceriem un to klasifikāciju, autentiskumu, kā arī lietojumu un apmierinātības teoriju. Metodoloģiskajā daļ…
'No hay libro, por malo que sea, que no tenga alguna cosa buena': la difusión de las novelle de Sebastiano Erizzo y Niccolò Granucci en la España del…
2019
En este artículo se ofrece un primer panorama acerca de la difusión y repercusión de las novelas de Sebastiano Erizzo y Niccolò Granucci en el Siglo de Oro, en particular de dos de sus obras principales, Le sei giornate (1567) y La piacevol notte et lieto giorno (1574). Las características de los ejemplares localizados y los datos recabados en torno a la circulación de ambas obras por tierras españolas permiten suponer que sus novelas, cuyo carácter moralista probablemente favoreciese su difusión, ejercieron un cierto influjo en la literatura áurea. Esta circunstancia invita a volver los ojos hacia las novelas de Sebastiano Erizzo y Niccolò Granucci, hasta ahora poco atendidas en el ámbito …
SARS-CoV-2 vaccine response and rate of breakthrough infection in patients with hematological disorders
2022
Abstract Background The clinical efficacy of SARS-CoV-2 vaccines according to antibody response in immunosuppressed patients such as hematological patients has not yet been established. Patients and methods A prospective multicenter registry-based cohort study conducted from December 2020 to December 2021 by the Spanish transplant and cell therapy group was used to analyze the relationship of antibody response at 3–6 weeks after full vaccination (2 doses) with breakthrough SARS-CoV-2 infection in 1394 patients with hematological disorders. Results At a median follow-up of 165 days after complete immunization, 37 out of 1394 (2.6%) developed breakthrough SARS-CoV-2 infection at median of 77 …
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 …

Experimental investigation on different rainfall energy harvesting structures
2018
In this paper proposes an experimental comparison between different rainfall harvesting devices and the study of the corresponding electrical rectifying circuit. More in detail, three harvesting structures are considered: the cantilever, the bridge and the floating circle. For each of the proposed structure, different waveforms have been acquired and discussed. The processed data have been compared in order to suggest the best choice for the rectifying circuit, from the simplest one to the most endorsed in the technical literature.
Dielectric response of BaTiO3 electronic states under AC fields via microsecond time-resolved X-ray absorption spectroscopy
2021
Abstract For the first time, the dielectric response of a BaTiO 3 thin film under an AC electric field is investigated using microsecond time-resolved X-ray absorption spectroscopy at the Ti K-edge in order to clarify correlated contributions of each constituent atom on the electronic states. Intensities of the pre-edge e g peak and shoulder structure just below the main edge increase with an increase in the amplitude of the applied electric field, whereas that of the main peak decreases in an opposite manner. Based on the multiple scattering theory, the increase and decrease of the e g and main peaks are simulated for different Ti off-center displacements. Our results indicate that these s…

Complex structural contribution of the morphotropic phase boundary in Na0.5Bi0.5TiO3 - CaTiO3 system
2019
Abstract The correlation between structure and dielectric properties of lead-free (1-x)Na0.5Bi0.5TiO3 - xCaTiO3 ((1-x)NBT - xCT) polycrystalline ceramics was investigated systematically by X-ray diffraction, combined with impedance spectroscopy for dielectric characterizations. The system shows high miscibility in the entire composition range. A morphotropic phase boundary (MPB), at 0.09 ≤ x
