A siliciclastic shallow-marine turbidite on the carbonate shelf of the Ordovician Baltoscandian palaeobasin
2019
A metre-scale thick siltstone–sandstone lobe is described within the Dapingian outer ramp argillaceous limestone facies of the Baltoscandian palaeobasin. This bed is referred to as the Volkhov Oil Collector in previous studies due to its hydrocarbon accumulation potential. It formed on the palaeoslope of the regional Jelgava Depression, which represents an elongated axial region of the deepest part of the Ordovician Baltoscandian sedimentary basin. Sedimentological and petrological analysis of this siliciclastic bed in core sections shows that it was deposited as a result of a single event of turbidite flow. The internal structure of the turbidite bed follows the classical Bouma divisions o…
Corundum Anorthosites-Kyshtymites from the South Urals, Russia: A Combined Mineralogical, Geochemical, and U-Pb Zircon Geochronological Study
2019
Kyshtymites are the unique corundum-blue sapphire-bearing variety of anorthosites of debatable geological origin found in the Ilmenogorsky-Vishnevogorsky complex (IVC) in the South Urals, Russia. Their mineral association includes corundum-sapphire, plagioclase (An61&ndash
An integrated analytical approach to define the compositional and textural features of mortars used in the underwater archaeological site of castrum …
2019
This paper aims to carry out an archaeometric characterization of mortar samples taken from an underwater environment. The fishpond of the archaeological site of Castrum Novum (Santa Marinella, Rome, Italy) was chosen as a pilot site for experimentation. The masonry structures reached the maximum thickness at the apex of the fishpond (4.70 m) and consisted of a concrete conglomerate composed of slightly rough stones of medium size bound with non-hydraulic mortar. After sampling, for a complete characterization of selected mortar fragments, different and complementary techniques (stereomicroscopy, polarizing optical microscopy, and X-ray powder diffraction analysis) were carried out in order…
Intercultural Communication and its Challenges Within the International Virtual Project Team
2019
With the advance of technology, face-to-face intercultural communication moves into the online virtual environment via electronic tools such as audio-video conferencing, email, messenger chat, platforms, groups, thus distances between individuals from different cultures are reduced and the exchange of information takes place within a few seconds. Cultural differences should not be a barrier to communication but an opportunity for development. International virtual project teams (IVPTs) can benefit from cultural diversity and effective intercultural communication, because it can enhance creativity and innovation within the project team, while at the same time team members are enriched by acq…
Penyagolosa Trails: From Ancestral Roads to Sustainable Ultra-Trail Race, between Spirituality, Nature, and Sports. A Case of Study
2019
[EN] The organization of an open-air sporting event involves a series of challenges. People are drawn by the desire to do sport, preferably in close contact with nature, so as to complement healthy lifestyles, and in search of air purity. Sporting organizations are increasingly searching for new locations that do not only attract athletes, but spectators and companions too. Races in natural parks provide the additional benefit of doing sport in a unique space, usually a transmitter of simplicity, pure air, and tranquillity. Organizing a mountain race in a natural park implies some issues. These are areas of great environmental richness that must be protected. Natural parks are places of ind…
L’ambiente d’apprendimento nella prima infanzia alla luce della prospettiva Montessoriana: un’indagine in Sicilia
2019
The following paper focus on the growing interest in structuring the learning environment in order to promote the psycho-social-attitudinal development of the infant. The montessorian approach enhances a child-friendly environment. It facilitates active participation in the child’s daily life, thus contributing towards a higher level of independence, self-awareness, self-esteem and self-evaluation. The survey conducted in June 2019 shows that in Sicily less people are adopting montessorian approach nowadays into the early childhood structures.
Formazione Service e-Learning: esperienza media-educativa
2023
The use of technology is an interesting device, which constitutes a useful self-training approach, related to an experience, from which to extract significant materials and traces of their personal learning. In Italy, Service Learning (SL) projects that use digital media in the university environment are still rare and therefore there are not many data and research results related to the introduction of SL in the training of future teachers. On the contrary, at the international level we find a vast scientific literature on SL and its applications, also in the academic field. Service e-Learning (Se-L) can in fact represent an essential approach for university education, which allows student…
Terrestrial Inputs Drive Seasonality in Organic Matter and Nutrient Biogeochemistry in a High Arctic Fjord System (Isfjorden, Svalbard)
2020
Climate-change driven increases in temperature and precipitation are leading to increased discharge of freshwater and terrestrial material to Arctic coastal ecosystems. These inputs bring sediments, nutrients and organic matter (OM) across the land-ocean interface with a range of implications for coastal ecosystems and biogeochemical cycling. To investigate responses to terrestrial inputs, physicochemical conditions were characterized in a river- and glacier-influenced Arctic fjord system (Isfjorden, Svalbard) from May to August in 2018 and 2019. Our observations revealed a pervasive freshwater footprint in the inner fjord arms, the geochemical properties of which varied spatially and seaso…
Temperature effects explain continental scale distribution of cyanobacterial toxins
2018
Insight into how environmental change determines the production and distribution of cyanobacterial toxins is necessary for risk assessment. Management guidelines currently focus on hepatotoxins (microcystins). Increasing attention is given to other classes, such as neurotoxins (e.g., anatoxin-a) and cytotoxins (e.g., cylindrospermopsin) due to their potency. Most studies examine the relationship between individual toxin variants and environmental factors, such as nutrients, temperature and light. In summer 2015, we collected samples across Europe to investigate the effect of nutrient and temperature gradients on the variability of toxin production at a continental scale. Direct and indirect…
A New Perspective on the Textile and Apparel Industry in the Digital Transformation Era
2022
The textile and apparel (fashion) industry has been influenced by developments in societal socio-cultural and economic structures. Due to a change in people’s preferences from economic functionality to supra-functionality beyond economic value, the fashion industry is at the forefront of digitalization. The growing digitalization in the fashion industry corresponds to digital fashion, which can satisfy the rapid shift in consumers’ preferences. This paper explores the evolving con-cept of innovations in digital fashion in the textile and apparel industry. Specifically, it centers on the evaluation of Amazon’s digital fashion initiatives, which have made the platform the Un…
