Kilpailu vaikuttaa nieriän ravintoon
2013
Lapin nieriäkannat ovat monin paikoin taantuneet uusien kalalajien levittäytymisen seurauksena. Tuore väitöskirjatutkimus osoittaa, että nieriä voi vaihtaa ravintoaan ja elinpaikkaansa vähentääkseen kilpailua muiden kalalajien kanssa. nonPeerReviewed
Feasibility of hyperspectral vegetation indices for the detection of chlorophyll concentration in three high Arctic plants: Salix polaris, Bistorta v…
2018
Remote sensing, which is based on a reflected electromagnetic spectrum, offers a wide range of research methods. It allows for the identification of plant properties, e.g., chlorophyll, but a registered signal not only comes from green parts but also from dry shoots, soil, and other objects located next to the plants. It is, thus, important to identify the most applicable remote-acquired indices for chlorophyll detection in polar regions, which play a primary role in global monitoring systems but consist of areas with high and low accessibility. This study focuses on an analysis of in situ-acquired hyperspectral properties, which was verified by simultaneously measuring the chlorophyll conc…
The Evaluation of Social and Professional Life Competences of University Students Through Service-Learning
2021
The view previously held in the university regarding teaching-learning processes has changed significantly over the past few years. Undoubtedly, in the case of Europe, this change of pedagogical model has gone hand in hand with the creation of the European Higher Education Area (EHEA). Some of the pivotal areas of EHEA are the independent work of the individual student, the social dimension of learning, and the acquiring of skills, which are not reduced to the mere technical and/or subject matter knowledge. Generic competences and the so-called “soft skills” have also become important, given their significant contribution to the students’ academic, personal, social, and professional develop…

Arginine-rich peptides are blockers of VR-1 channels with analgesic activity
2000
Vanilloid receptors (VRs) play a fundamental role in the transduction of peripheral tissue injury and/or inflammation responses. Molecules that antagonize VR channel activity may act as selective and potent analgesics. We report that synthetic arginine-rich hexapeptides block heterologously expressed VR-1 channels with submicromolar efficacy in a weak voltage-dependent manner, consistent with a binding site located near/at the entryway of the aqueous pore. Dynorphins, natural arginine-rich peptides, also blocked VR-1 activity with micromolar affinity. Notably, synthetic and natural arginine-rich peptides attenuated the ocular irritation produced by topical capsaicin application onto the eye…
Territorialization in Political Discourse: A Pragma-Linguistic Study of Jerzy Buzek’s Inaugural Speeches
2011
The purpose of this study is to review some discursive strategies used to (de)territorialize the European public sphere by the newly elected President of the European Parliament Jerzy Buzek. A corpus of his inaugural speeches (over 7,000 words) is examined in order to identify salient pragma-linguistic devices, such as for example high-frequency references, linguistic markers of identities, values and interests, as well as metaphors and argumentative schemata. These are presumed to have been used by Buzek to territorialize the presidential office: to position himself as its leader, to establish his credibility, to become its agenda-setter. Additionally, the analysis focuses on the way Buzek…
Ariosto barocco e neobarocco
2010
A partire dall’analisi di quello spettacolo di svolta nella storia del teatro contemporaneo che è stato lo Orlando Furioso di Ronconi-Sanguineti, si sviluppa un prolungato ed analitico excursus sulla vitalità del “mitemi” del gran poema dell’Ariosto dal Rinascimento ai nostri giorni, attraverso le innumerevoli rielaborazioni delle spettacolo - teatro di drammaturgia, teatro d’opera, pastorale, danza, teatro di varietà, etc. - e quelle dei media - cinema, TV, fumetto, arti in genere. Dal “Concerto Caccini” al “balletto equestre”, da Lulli ad Händel, da Vivaldi ad Haydn, da Millos alla “modern dance”, emerge così l’importanza degli archetipi mitici che hanno ispirato per cinque secoli tutte l…
Prote Hyle. Notions of Matter in the Platonic and Aristotelian Traditions
2017
How do we experience matter? Does it present itself to the senses? Or is it only an empty substratum that cannot be grasped if deprived of all sensible qualities? Is it perceived as a continuum, or rather intellectually reconstructed through mental and logical forms? Or is it that the very idea of a continuum is itself the outcome of mental abstraction? The nature of matter has been a central issue for philosophy since its inception. The constant oscillation of ancient thought between ma er as indeterminateness that does not have a concept and does not even properly exist - and matter as a principle that allows one to think plurality and otherness, that reaches even into the realm of the in…
Mineral control of arsenic content in thermal waters from volcano-hosted hydrothermal systems: Insights from island of Ischia and Phlegrean Fields (C…
2006
This paper documents arsenic concentrations in 157 groundwater samples from the island of Ischia and the Phlegrean Fields, two of the most active volcano-hosted hydrothermal systems from the Campanian Volcanic Province (Southern Italy), in an attempt to identify the environmental conditions and mineral-solution reactions governing arsenic aqueous cycling. On Ischia and in the Phlegrean Fields, groundwaters range in composition from NaCl brines, which we interpret as the surface discharge of deep reservoir fluids, to shallow-depth circulating fluids, the latter ranging from acid-sulphate steam-heated to hypothermal, cold, bicarbonate groundwaters. Arsenic concentrations range from 1.6 to 690…
Does endovascular treatment with curative intention have benefits for treating High-grade AVM versus radiosurgery? Efficacy, safety, and cost-effecti…
2021
BACKGROUND: The treatment of high-grade arteriovenous malformations (AVMs) remains challenging. Microsurgery provides a rapid and complete occlusion compared to other options, but is associated with undesirable morbidity and mortality. The aim of this study was to compare the occlusion rates, incidence of unfavorable outcomes, and cost-effectiveness of embolization and stereotactic radiosurgery (SRS) as a curative treatment for high-grade AVMs.METHODS: A retrospective series of 57 consecutive patients with high-grade AVM treated with embolization or SRS, with the aim of achieving complete occlusion, was analyzed. Demographic, clinical, and angio-architectonic variables were collected. Both …
