Accounting More Precisely for Peat and Other Soil Carbon Resources

2012

In the context of “recarbonization”, it is important to know where the soil C stocks are located and how much of these are prone to emission to the atmosphere. While it may appear to be a trivial question considering available global estimates and maps, yet there is a strong need to emphasize that erroneous estimates are made in assessing the global soil C stocks. Without doubt, peatlands hold the single most important soil C stock at the global scale, and these soils are mostly located in the northern latitudes between 50°N and 70°N. However, there are additional wetlands or other ecosystems which also hold potentially relevant amounts of soil C stocks. From the soil science perspective, i…

Children Witnessing Domestic and Family Violence: A Widespread Occurrence during the Coronavirus Disease 2019 (COVID-19) Pandemic

2021

Across the world, children and adolescents are exposed daily to toxic levels of violent behaviors, including domestic and family violence. Violence increasingly has permeated and profoundly affected the lives of children, who are the most vulnerable members of society.1 Pediatric societies in Europe and North America have raised great concern over the effect that abusive experiences will have on present and future generations.1, 2, 3, 4 The global spread of coronavirus disease 2019 (COVID-19) during the past year has dramatically worsened the situation, contributing to a further increase in violence and aggression within households. Reports of domestic abuse and family violence have increas…

Evolutionary and phenotypic characterization of spike mutations in a new SARS-CoV-2 Lineage reveals two Variants of Interest

2021

Molecular epidemiology of SARS-CoV-2 aims to monitor the appearance of new variants with the potential to change the virulence or transmissibility of the virus. During the first year of SARS-CoV-2 evolution, numerous variants with possible public health impact have emerged. We have detected two mutations in the Spike protein at amino acid positions 1163 and 1167 that have appeared independently multiple times in different genetic backgrounds, indicating they may increase viral fitness. Interestingly, the majority of these sequences appear in transmission clusters, with the genotype encoding mutations at both positions increasing in frequency more than single-site mutants. This genetic outco…

Mapping the Idea of Europe : Cultural Production of Border Imaginaries through Heritage

2021

In contrast to recent reinforcements of Europe's internal and external borders due to the refugee situation on the Mediterranean and the Covid-19 outbreak, talk of European borders has in the past decades focused on the freedom of mobility guaranteed by the Schengen treaty. In many senses, free intra-European mobility has become a recited truth in the EU discourse: a phrase that hides under its repetition the gap between its implied content and empirical realities of many of those who are affected by European borders’ exclusive tendencies. Through the concept of borderscape, this article focuses on the role that cultural products – especially maps exhibited at heritage sites – have in recit…

Why reg. (eu) no. 1103/2016 and 1104/2016 impact on the european citizens daily life?

2021

Why families do need the tools and instruments implemented by PSEFS Project? Why this is not an issue for lawyers, judges and University professors only. The answer to this question is that Reg. (EU) no. 1103/2016 and no. 1104/2016 impact on the European citizens daily life. We follow the problems of a young couple in order to have a better understanding and an evidence of this statement.

Extra-virgin olive oils storage: Effect on constituents of biological significance

2021

Abstract The high oxidative stability of virgin olive oil with respect to other vegetable oils is mainly due to its fatty acid composition, in particular, to the high monounsaturated-to-polyunsaturated ratio, and to the presence of minor compounds that play a major role in preventing oxidation. In spite of its high stability, virgin olive oil is susceptible to oxidative processes, such as enzymatic oxidation, photooxidation, and autoxidation, which mainly occur during processing and storage. Generally, extra-virgin olive oil has a relatively long shelf life of 16–18 months of storage at room temperature. The study of shelf life is generally based on determining of quality parameters (acidit…

Ernesto Basile e le Esposizioni Agricole Siciliane dei primi anni del ‘900

2020

In 1891 the IV Italian National Exposition was held in Palermo, the first to have a southern city as its protagonist. The area on which the pavilions were built, obtained from the expropriation of the land belonging to the Prince of Villafranca, lent itself from the following year to accommodate the housing development and new buildings to complete the Via della Libertà, a high-bourgeois boulevard that already in 1850, by cutting the same "Firriato" of the Villafranca family, had marked the expansion towards the north of the city and seen the construction of the first buildings on its eastern front. Ernesto Basile was one of the main designers of the event and future urban creations. Althou…

Determination of mercury at picogram level in natural waters with inductively coupled plasma mass spectrometry by using 3D printed metal scavengers

2019

The determination of ultra-trace concentrations of Hg in natural water samples via preconcentration using 3D printed metal scavenger technique followed by inductively coupled plasma mass spectrometry (ICP-MS) was developed. The determination of Hg in certified reference material ERM-CA615 (groundwater) was performed with high accuracy and precision resulting in recovery of 100 ± 3% and RSD <2.5%, respectively. Selective laser sintering (SLS) 3D printing was used to fabricate the scavengers using a mixture of polyamide-12 powder with thiol-functionalized silica. The preconcentration procedure is based on the adsorption of Hg on the scavenger and followed by elution of the preconcentrated Hg …
