Singing is what we do (together) - redefining "together" : A comparative study

2021

This article discusses the impact that the Covid-19 pandemic has had on singing with children in schools by providing a descriptive analysis of a comparative look at children's experiences of their singing habits and emotional well-being during the first Covid-19 lockdown. Covid-19 has established itself as (for now) an ever-present variable in our daily lives. This paper offers a descriptive analysis of a comparative study of the Covid-19 lockdown(s) influence on children's singing habits and emotional well-being in Italy, Austria, and Finland. A survey was carried out on children and young people aged 10-20 from Austria, Finland, and Italy on how the Coronavirus lockdown has impacted thei…

Rauhan sairaalan evakuoiminen ja sen vaikutukset sijoitussairaaloihin toisen maailmansodan aikana

2017

Tässä tutkielmassa tarkastelun kohteena on Rauhan mielisairaalan evakuoiminen ja sen vaikutukset sijoitussairaaloihin toisen maailmansodan aikana. Rauhan mielisairaala sijaitsi Joutsenossa, Kaakkois-Suomessa. Vaikka Joutseno ei ollut varsinaisella sotatoimialueella eikä alue joutunut alueluovutusten kohteeksi, sairaala evakuoitiin kuitenkin kolme kertaa. Tavoitteena on tutkia evakuointeihin vaikuttaneita syitä, evakuointien käytännön toteutusta sekä piirimielisairaaloiden toimintaa sota-aikana, koska Rauhan sairaala oli piirimielisairaala ja potilaiden sijoitussairaalat olivat myös hoidollisesti samantasoisia sairaaloita. Potilaiden hoitoa vaikeuttivat sairaaloiden tilanahtaus, sillä sairaa…

Consolidation tests on the graffiti of the Steri’s prison with nanotechnological Ca(OH)2 dispersed in iso-propanol

2009

The combination of weathering and human activities often induce pyhisicochemical alteration on the surface of wall paintings. One of the most still largely used restoration techniques for these works of art, is based on the application of organic polymers. Due to their ability to stick detached and powdered pigments,these products provide an immediate consolidating effects. Unfortunately, both their aging and their pyhisicochemical incompatibility with the inorganic support can have serious consequences also causing further damage to the work of art. In this paper a new technological approach is presented based on the use of Ca(OH)2 nanoparticles dispersed in isopropanol. Some applicative t…

Effect of temperature on anaerobic treatment of black water in UASB-septic tank systems

2007

The effect of northern European seasonal temperature changes and low temperature on the performance of upflow anaerobic sludge blanket (UASB)-septic tanks treating black water was studied. Three UASB-septic tanks were monitored with different operational parameters and at different temperatures. The results indicated the feasibility of the UASB-septic tank for (pre)treatment of black water at low temperatures with respect to removal of suspended solids and dissolved organic material. Inoculum sludge had little effect on COD(ss) removal, though in the start-up phase some poorly adapted inoculum disintegrated and washed out, thus requiring consideration when designing the process. Removal of …

Application of molecular imprinted polymers for selective solid phase extraction of bisphenol A

2016

Selective molecularly imprinted polymers (MIPs) with bisphenol A as template were synthesized using the non-covalent imprinting approach. MIPs were prepared using thermally initiated polymerization with 1,1’-azobis(cyclohexanecarbonitryle) (ACHN) as initiator and ethylene glycol dimethacrylate (EDMA) as a cross-linking agent. The tested functional monomers included methacrylic acid, acrylamide, and 4-vinylpyridine. The selectivity of the BPA-MIP for the solid phase extraction of bisphenol A was tested in samples containing other related alkylphenols. The polymers prepared in acetonitrile using methacrylic acid or acrylamide as monomer showed the highest selectivity towards target analyte (t…

Chemical weathering of volcanic rocks, Pantelleria Island: information from soil profile and soil solution investigations

2007

Concentrations of major, minor and trace elements were determined in soil profiles and soil solutions from the island of Pantelleria, Sicily Channel, to evaluate the weathering extent of soils evolved on trachytic and pantelleritic rocks and the aqueous transport of elements by their soil solutions. The chemical index of alteration (CIA) indicates a low-to-moderate degree of weathering; consistently, the mineralogical and geochemical imprints of the parent rocks are generally preserved. The chemical weathering appears to be incongruent, owing to primary minerals and glass dissolving to a variable degree while secondary minerals have formed. Based on the calculated saturation state of primar…

HIGH-RESOLUTION SEISMIC SURVEY IN THE WESTERN CALABRIA AND EASTERN SICILY OFFSHORE: IMPLICATIONS WITH VERTICAL TECTONICS

2016

High-resolution seismic data acquired along the continental shelf/upper slope offshore of Capo Vaticano (western Calabria), Milazzo Promontory and Mt. Etna (eastern Sicily) allow to provide new insights on vertical mobility related to active tectonics. A number of depositional sequences bounded by unconformities or correlative para-conformities were recognized on Sparker profiles in the first 200-300 m below the sea-floor. The most recent sequence overlays a widespread erosional surface that ostensibly formed during the sea level stillstand of the Last Glacial Maximum (LGM), whereas a stack of depositional sequences, which are interpreted as representing the falling and low-stand systems tr…

Vertically Aligned Nanowires and Quantum Dots: Promises and Results in Light Energy Harvesting

2023

The synthesis of crystals with a high surface-to-volume ratio is essential for innovative, high-performance electronic devices and sensors. The easiest way to achieve this in integrated devices with electronic circuits is through the synthesis of high-aspect-ratio nanowires aligned vertically to the substrate surface. Such surface structuring is widely employed for the fabrication of photoanodes for solar cells, either combined with semiconducting quantum dots or metal halide perovskites. In this review, we focus on wet chemistry recipes for the growth of vertically aligned nanowires and technologies for their surface functionalization with quantum dots, highlighting the procedures that yie…

The role of the agreement as a tool for management of property relations in cases of cross border marriages and civil unions/partnerships registered …

2021

The essay examines the role of the agreement as a tool for managing property relationships in crossborder marriages and registered partnerships, in light of EU Regulations 1103 and 1104 of 2016, on the property regimes of international married or registered couples. The main prerogative of such acts is the recognition of the parties? freedom to choose the court and the applicable law. The law governing the matrimonial property regimes, or the property consequences of registered partnerships, has universal scope. This agreement in the form envisaged, which is backed by the need for legal certainty and predictability of the applicable rules, means that the spouses, in family problems which ha…
