Microalgae-bacteria consortia for urban wastewater treatment
2021
Los consorcios de microalgas y bacterias surgen como una opción idónea en el marco de las tecnologías sostenibles para el tratamiento de aguas residuales. Los mecanismos de eliminación de contaminantes son el resultado de interacciones ecológicas directas y/o indirectas entre las microalgas y las bacterias autóctonas de las aguas residuales. Para diseñar sistemas eficaces que incorporen consorcios de microalgas y bacterias es necesario comprender las interacciones ecológicas entre ambas comunidades dentro de los procesos de tratamiento de aguas residuales. El objetivo principal de este trabajo de investigación es, por tanto, estudiar y explorar las interacciones ecológicas para mejorar el t…
Tiesības uz taisnīgu tiesu un tiesības uz komercnoslēpumu
2016
Nereti administratīvā procesa tiesā laikā rodas nepieciešamība noteikt ierobežojumu lietas dalībniekiem iepazīties ar noteiktu daļu lietas materiālu. Šādas tiesas tiesības ir noteiktas Administratīvā procesa likuma 145.panta ceturtajā daļā, lai aizsargātu komerciālo noslēpumu. Tas ir uzskatāms par ierobežojumu tādu tiesību uz taisnīgu tiesu elementiem kā tiesības iepazīties ar lietas materiāliem un tiesības tikt uzklausītam. Maģistra darba mērķis ir izdarīt secinājumus un sniegt priekšlikumus par tiesību uz taisnīgu tiesu un tiesību uz komercnoslēpumu kolīzijas risinājuma vadlīnijām, kas būtu jāņem vērā administratīvajā procesa tiesā. Maģistra darba uzdevumi darba mērķa sasniegšanai ir apko…
High-rise timber architecture: an opportunity for the sustainability of the built environment
2019
Bioeconomy, circular economy, land use reduction, sustainable use of natural resources, reduction of CO2 emissions in the atmosphere and recycling are the keywords which the building world must face in the near future, as the environmental emergency can no longer be postponed. In order to disseminate in the scientific community the different possibilities of timber as a sustainable building material throughout its whole life cycle and to provide the professionals with suitable decision-making tools for a conscious design, within the cultural and scientific scenario of the recent years, the paper serves as a moment of reflection highlighting how a closer integration between different sectors…
Timber framed with masonry infill: a historical anti-seismic device. The Portuguese Pombaline gaiola.
2017
La ricostruzione postsismica e la prevenzione sismica sono stati da sempre un fondamento costruttivo.Questo studio analizza la tipologia costruttiva della gaiola pombalina, un sitema costruttivo e strutturale molto diffuso in Portogallo ma non solo, adottato a Lisbona a seguito del terremoto del 1755. Si analizzano i materiali e le tecniche costruttive, gli elementi utili al rinforzo e consolidamento della struttura muraria, ampiamente diffuso in area mediterranea a partire dal XVIII secolo.Questo sistema costruttivo può e deve anche oggi essere considerato un utile presidio antisismico da riconoscere e preservare da interventi incolti, se non addirittura da incongrue demolizioni. Post-seis…
Differences between female and male gamers and gender-specific risk-factors for internet gaming disorder (IGD)
2020
Introduction: Videogames have become more popular across females, although their widespread diffusion among males. How- ever, few studies have examined differences between female and male gamers and gender-specific risk factors for Internet Gaming Disorder (IGD). Objectives: The study aimed to describe males and females’ differ- ences in a sample of gamers, and to identify gender-specific risk- factors for IGD, accounting for alexithymia, playing habits, and other perceived stressors. Methods: Participants were gamers joining online communities, tested by IGDS-SF9 and TAS-20 for alexithymia. To explore isk-factors for IGD (outcome: IGD>=21), we set a binary logistic regression stratified…

Carbon Nitride-Based Catalysts for High Pressure CO2 Photoreduction
2022
In the current research, the productivity of CO2 photoreduction has been boosted by performing the reaction in an innovative photocatalytic reactor, which allows for operation up to 20 bar. A set of photocatalysts were used, including three types of pristine TiO2, i.e., one commercially prepared (Evonik P25), one home-prepared by flame spray pyrolysis (FSP), and one obtained by the hydrolysis of TiCl4 (TiO2exCl), a bare thermo-exfoliated carbon nitride (C3N4-TE), and binary materials composed of TiO2 and C3N4-TE. The photoreduction was carried out in water at pH 14 and in the presence of Na2SO3 as a hole scavenger. Hydrogen and very small amounts of CO were detected in the head space of the…
