Preparation of photocatalysts by chemical methodologies
2021
Abstract The synthesis of photocatalytic materials is an important task for obtaining better results in terms of activity and/or selectivity in photocatalysis. This chapter reports an overview of the main methodologies using physical techniques to obtain bulky, supported powders or films and coatings to be used as heterogeneous photocatalysts. The classical chemical methodologies for the preparation of photocatalytic materials are presented in the previous chapter, so the information presented here complements the aforementioned one. Materials scientists and engineers have made significant progresses in the improvement of methods of synthesis of nanomaterial solids by developing different a…
Self-efficacy and performance of the roundhouse kick in taekwondo
2014
[ES] El desarrollo de escalas de autoeficacia permite el análisis de las percepciones de los deportistas y el examen de la relación entre dichas percepciones y el rendimiento. El objetivo de este estudio fue (1) desarrollar una escala específica de autoeficacia para una tarea de taekwondo, la patada circular, y (2) analizar el rendimiento deportivo y su relación con los resultados de dos escalas de autoeficacia (específica y general) en función del género de los deportistas. En el estudio participaron 43 taekwondistas (33 hombres y 10 mujeres). Se administraron las escalas de autoeficacia Física (PSE) y Específica (RKSES). Los datos de rendimiento (fuerza de impacto y tiempo total de respue…
Recommendation of RILEM TC237-SIB: protocol for characterization of recycled asphalt (RA) materials for pavement applications
2018
This recommendation proposes an experimental protocol to characterize Recycled Asphalt (RA) materials. The guidelines presented in this document are based on the results of a Round Robin Test (RRT) organized by the RILEM Technical Committee 237-SIB “Testing and characterization of sustainable innovative bituminous materials and systems” and provide information on the testing procedure, data analysis and indications for the preparation of a test report.
Medical English in Italian University Courses in Sports Sciences: Some Issues in Focus
2014
Over the last few decades, the increasingly rapid progress of medical science and technology, together with the growing importance of English as the language of international communication, has made the study of medical English a crucial segment in the curriculum of medical undergraduates. In Italy, medical topics are studied not only in medical degree courses but also in those of sports sciences. This paper focuses attention on some medical English-related issues in sports sciences degree courses in Italian universities. More precisely, the work is divided into four main parts. The first part raises the terminological question concerning the denomination of the discipline “lingua inglese”/…

The Directive 2014/95/EU – Is there a “New” Beginning for CSR in Romania?
2017
Abstract The global commandments of sustainable development, assumed and translated by the EU into a series of communications and resolutions, have found themselves a new (and more powerful) expression into the “Directive 2014/95/EU (…) as regards disclosure of non-financial and diversity information by certain large undertakings and groups”; in order to increase the transparency of their sustainability-related actions and results, these companies need to report (starting from 2018, by referring to the financial year 2017) information “relating to, as a minimum, environmental, social and employee matters, respect for human rights, anti-corruption and bribery matters”. As regards the Romania…
Sarraute's plays : poplyphony and enunciation
2014
The corpus is formed of six plays of Nathalie Sarraute; it hides a duplication of enunciation types in the characters’ dialogue. This duplication is latent due to personal pronouns and verb tenses’ neutralization. The transition from an enunciation layer to another is not marked at all or not traditionally marked. Therefore, deciphering will be more complicated to any reader, listener or spectator. These works of art are also highly polyphonic in terms of enunciation as in semantics, as several voices are intertwined and as the characters resort to authorities of point of view. Thus, readers, listeners and spectators should identify enunciation sources and “other” authorities of point of vi…
Using moss and lichens in biomonitoring of heavy-metal contamination of forest areas in southern and north-eastern Poland.
2017
Abstract In the years 2014–2016 biomonitoring studies were conducted in the forest areas of south and north-eastern Poland: the Karkonosze Mountains, the Beskidy Mountains, the Borecka Forest, the Knyszynska Forest and the Bialowieska Forest. This study used epigeic moss Pleurozium schreberi and epiphytic lichens Hypogymnia physodes. Samples were collected in spring, summer and autumn. Approximately 500 samples of moss and lichens were collected for the study. In the samples, Mn, Ni, Cu, Zn, Cd, Hg and Pb concentrations were determined. Based on the obtained results, the studied areas were ranked by extent of heavy-metal deposition: Beskidy > Karkonosze Mountains > forests of north-eastern …
The impact of soil erosion on soil fertility and vine vigor. A multidisciplinary approach based on field, laboratory and remote sensing approaches
2018
Soil erosion processes in vineyards, beyond surface runoff and sediment transport, have a strong effect on soil organic carbon (SOC) loss and redistribution along the slope. Variation in SOC across the landscape can determine differences in soil fertility and vine vigor. The goal of this research was to analyze the interactions among vines vigor, sediment delivery and SOC in a sloping vineyard located in Sicily. Six pedons were studied along the slope by digging 6 pits up to 60 cm depth. Soil was sampled every 10 cm and SOC, water extractable organic carbon (WEOC) and specific ultraviolet absorbance (SUVA) were analyzed. Erosion rates, detachment and deposition areas were measured by the po…
Multi O- and S-isotopes as tracers of black crusts formation under volcanic and non-volcanic atmospheric conditions in Sicily (Italy)
2020
International audience; The deterioration of monument or building stone materials is mostly due to the growth of black crusts that cause blackening and disaggregation of the exposed surface. This study reports on new oxygen (δ17O, δ18O and Δ17O) and sulphur (δ33S, δ34S, δ36S, Δ33S and Δ36S) isotopic analyses of black crust sulphates formed on building stones in Sicily (Southern Italy). The measurements are used to identify the possible influence of volcanic emissions on black crust formation. Black crusts were mostly sampled on carbonate stone substrate in different locations subject to various sulphur emission sources (marine, anthropogenic and volcanic). Unlike atmospheric sulphate aeroso…
