Seasonal variations in endurance performance, and aerobic and anaerobic variables in competitive cross country skiers
2016
Cross country skiing is known as an endurance sport and both aerobic and anaerobic systems have a major impact on performance in cross country skiers. Coaches and athletes use periodized training programs to optimize physiological adaptations and increase performance. Knowing how the major aerobic and anaerobic variables change during the course of one ski season will allow better implementation of training programs. This study examined variations in endurance performance, and how that relates to the variation in different aerobic and anaerobic variables. There were 19 subjects in the study, 11 male and 8 female. All subjects were competitive cross country skiers. The study took place over …
Toxicity of silver nanoparticles to Lumbriculus variegatus is a function of dissolved silver and promoted by low sediment pH
2018
Toxicity of silver nanoparticles (AgNPs) to benthic organisms is a major concern. The use of AgNPs in industry and consumer products leads to increasing release of AgNPs into the aquatic environment—sediments being the major sink. Effects of sediment pH on the toxicity of AgNPs to benthic oligochaeta Lumbriculus variegatus were studied in a 23‐d toxicity test. Artificially prepared sediments (pH 5 and 7) were spiked with varying concentrations of uncoated AgNP, polyvinylpyrrolidone (PVP)‐coated AgNP, and silver nitrate (AgNO3) as dissolved Ag reference. Number of individuals and biomass change were used as endpoints for the toxicity. The toxic effects were related to the bioaccessible conce…
Biological responses of midge (Chironomus riparius) and lamprey (Lampetra fluviatilis) larvae in ecotoxicity assessment of PCDD/F-, PCB- and Hg-conta…
2016
We evaluated the utility of chironomid and lamprey larval responses in ecotoxicity assessment of polychlorinated dibenzo-p-dioxins, dibenzofurans (PCDD/F)-, polychlorinated biphenyls (PCB)- and mercury (Hg)-contaminated river sediments. Sediment samples were collected from the River Kymijoki with a known industrial pollution gradient. Sediment for the controls and lamprey larvae were obtained from an uncontaminated river nearby. Contamination levels were verified with sediment and tissue PCDD/F, PCB and Hg analyses. Behaviour of sediment-exposed chironomid and lamprey larvae were measured with Multispecies Freshwater Biomonitor© utilizing quadrupole impedance conversion technique. In additi…
The role of Christianity in the European Union’s heritage and history initiatives
2022
In its political discourse, the European Union balances Christian heritage, the secularization of European societies, liberal values and Europe’s culturally and religiously diverse contemporary reality. This article explores how the European Union narrates the story of Europe and the role of Christianity in this narrative. This exploration is based on two qualitative case studies focusing on key heritage and history initiatives of the European Commission and the European Parliament: the European Heritage Label and the House of European History. The article argues that issues related to Christianity become easier to handle for the European Union when they are dealt with as memory, tradition…
Prosociality and life satisfaction: A daily-diary investigation among Spanish university students
2018
Abstract With a diary study, we tested the positive effect of prosociality on life satisfaction. Fifty-six Spanish undergraduate students (45 females; Mage = 21.08 years) rated their life satisfaction, prosociality, self-esteem, and physical appearance for 5 consecutive days. Multilevel results indicated that within-individual positive deviations in prosociality (i.e., behaving more prosocial than usual) were uniquely and significantly associated with higher life satisfaction on that specific day. Students' self-esteem, physical appearance, and positive daily events were also predictive of life satisfaction. Exploratory analyses revealed that the positive effect of prosociality on life sati…

Separation of palladium and silver from E-waste leachate : effect of nitric acid concentration on adsorption to Thiol scavenger
2022
The development of recovery techniques for metals present in low concentrations in E-waste, such as silver and palladium, is important from the aspect of the circular economy. Adsorption of palladium and silver was studied in detail in a batch process with silica-based Thiol scavenger from nitric acid leachate of waste printed circuit boards (PCBs). High adsorption efficiencies of Pd(II) and Ag(I), >97%, were reached in nitric acid concentrations below 3 mol L−1. At higher acid concentrations, adsorption efficiency of Ag(I) decreased drastically which enables the separation of Ag(I) and Pd(II) based on nitric acid concentration in sample solution. Pd(II) and Ag(I) followed pseudo 2nd order …
Autonomie locali e politiche pubbliche per l’economia digitale
2019
La rivoluzione digitale ha causato in questi anni un significativo disalli- neamento tra chi subisce le conseguenze delle nuove forme economiche e la distribuzione delle responsabilità regolative tra i diversi attori. Il risultato è che le città sono le più colpite dai cambiamenti in atto, ma non sempre hanno strumenti adeguati a fronteggiare le novità e interpretarle secondo i propri bisogni e necessità. A partire da queste premesse, il presente lavoro analizza l’impatto delle tecnologie digitali sul tessuto socio-economico delle città e ragiona sulle contrapposte esigenze di politiche ritagliate sulle spe- cificità locali e, al contempo, di regole omogenee per il mercato. Su questa inelim…
‘‘This is my home, too’’: Migration, spectrality and hospitality inRoberta Torre’s Sud Side Stori (2000)
2011
The article explores Roberta Torre’s film Sud Side Stori (2000), an extravagant Italian re-vision of Romeo and Juliet set in the Sicilian city of Palermo which displays awareness of the global circulation of the story of the two ‘‘star-crossed lovers’’. In the film, which combines neo-realist cinematographic techniques with the artificial style of the musical, Shakespeare’s young lovers become Toni Giulietto, a lousy local rock singer, and Romea Wacoubo, a beautiful Nigerian prostitute who falls in love with him when she sees him standing on his balcony. Not unlike West Side Story, the inter-racial passion between Toni and Romea exacerbates pre-existing ethnic conflicts. It is opposed not o…
Shakespeare, Art and Artifice: An Interview with Stuart Sillars
2019
Ahead of the publication of his forthcoming book, Shakespeare Seen: Image, Performance and Society (Cambridge, 2018), Stuart Sillars sat down for an interview with Perry McPartland. The discussion revisited a number of topics that Sillars has explored in his various publications on Shakespeare, including Shakespeare’s aesthetic strategies of transformation, the relationship his work takes to the visual, and the uses to which Shakespeare puts aesthetic artifice. The interview was conducted in two parts over a very nearly adequate Skype connection in the summer of 2018.
