Major ions and trace elements composition of rainwater around the two industrial areas of Milazzo and Priolo Gargallo (Sicily - Italy)

2023

This database shows the concentration of major ions and trace elements in rainwater from two polluted industrial areas of Sicily, Milazzo and Priolo Gargallo, collected from June 2018 to July 2019, through a network of 11 bulk collectors to sample bulk atmospheric deposition, for a total of 131 samples collected. Different sources, both natural and anthropogenic, for both major ions and trace elements have been recognised. This study also highlighted some critical issues with common methods of sampling and analysing atmospheric deposition. The analysis and comparison of two different aliquots, filtered and unfiltered rainwater, has shown that the filtration method removes from the sample a …

Chemistry of atmospheric depositions over two polluted industrial areas of Sicily (Italy)

2021

Dry and wet depositions provide the pathways through which particles and gases emitted into the atmosphere return to the Earth’s surface. Bulk deposition is defined as the sum of dry and wet deposition, which is characterized by water-soluble and insoluble chemical species. Recent studies (e.g. Castillo et al., 2017) showed that most of the atmospheric deposition in Europe occurs in the wet form, but in southern European regions the role of dry contribution can be as significant as that of wet deposition. In the framework of the multidisciplinary project “CISAS” (Centro Internazionale di Studi Avanzati su Ambiente, ecosistema e Salute umana), bulk depositions were monthly sampled over two p…

Sampling and analysis methodology of atmospheric deposition: a study case form Mount Etna

Mount Etna volcanic emissions signature on the chemical composition of bulk atmospheric deposition in Sicily, Italy.

2022

Mt. Etna, on the eastern coast of Sicily (Italy), is one of the most active and most intensely monitored volcanoes on the Earth, widely recognized as a big source of volcanic gases, such as CO2, SO2, halogens, and many trace elements, including technological critical elements (TCEs), to the atmosphere on a regional and global scale. Mt. Etna emissions account for a significant percentage of the worldwide average volcanic budget and especially during eruptive periods, its products can be dispersed over great distances and they influence the chemical composition of the atmosphere of other continents too. The current knowledge about the geochemical cycle of TCEs is still scarce, nevertheless, …

Carbon Dots Dispersed on Graphene/SiO2/Si: A Morphological Study

2019

Low-dimensional carbon materials occupy a relevant role in the field of nanotechnology. Herein, the authors report a study conducted by atomic force microscopy and Raman spectroscopy on the deposition of carbon dots onto graphene surfaces. The study aims at understanding if and how the morphology and the microstructure of chemical vapor deposited graphene on Si/SiO2 may change due to the interaction with the carbon dots. Potential alteration in the graphene's electrical properties might be detrimental for optoelectronic applications. The deposition of carbon dots dispersed in water and ethanol solvents are explored to investigate the effect of solvents with different fluidic properties. The…

E-repozitoriji atvērtās zinātnes kontekstā

2020

Bakalaura darba mērķis ir noskaidrot, kādas kompetences un prasmes saistībā ar repozitorijiem atvērtās zinātnes kontekstā ir nepieciešamas informācijas speciālistam. Darbā tiek pētīti ar atvērto zinātni saistīti jēdzieni un koncepcijas, aprakstīti ar repozitorijiem saistīti jautājumi, situācija Latvijā, kā arī kompetenču profili un modeļi, kuros apkopotas informācijas speciālistiem nepieciešamās prasmes un kompetences atvērtās zinātnes kontekstā. Empīriskajā daļā ir veikta kompetenču profilu un modeļu kontentanalīze un analizētas intervijas ar informācijas speciālistēm, kuru darbs ikdienā saistīts ar atvērtās zinātnes jautājumiem. Pētījuma rezultātā tika apkopotas daudzveidīgās prasmes un k…

Why Open Educational Resources Repositories fail - Review of Quality Assurance Approaches

2014

Regardless of the amount of open educational resources (OER) available, many learning object repositories LORs fail to attract active users and sustainable funding solutions. Previous studies indicate that quality of OER plays a significant role in the success of the repositories; however, there is a lack of systematic deeper understanding of this connection. In this qualitative study we interviewed 35 managers/developers of 27 national, thematic and federated LORs in regards of the LORs’ quality approaches and success. The key findings of this study show that comprehensive quality approach leads to success of the repository in most cases, the key instruments for quality assurance being exp…

Beta-Blocker Use in Older Hospitalized Patients Affected by Heart Failure and Chronic Obstructive Pulmonary Disease: An Italian Survey From the REPOS…

2022

Beta (β)-blockers (BB) are useful in reducing morbidity and mortality in patients with heart failure (HF) and concomitant chronic obstructive pulmonary disease (COPD). Nevertheless, the use of BBs could induce bronchoconstriction due to β2-blockade. For this reason, both the ESC and GOLD guidelines strongly suggest the use of selective β1-BB in patients with HF and COPD. However, low adherence to guidelines was observed in multiple clinical settings. The aim of the study was to investigate the BBs use in older patients affected by HF and COPD, recorded in the REPOSI register. Of 942 patients affected by HF, 47.1% were treated with BBs. The use of BBs was significantly lower in patients with…
