Citizen science: uno strumento di successo per monitorare le specie aliene marine. Il caso studio nelle acque della Sicilia (Mediterraneo centrale)
2019
L’introduzione di specie non indigene invasive (IAS, organismi introdotti in aree esterne al loro areale naturale con comportamento invasivo) è considerata una delle maggiori minacce alla biodiversità e al funzionamento degli ecosistemi naturali (Katsanevakis et al. 2014, Vergeś et al. 2016). Una specie non-nativa (NIS) può diventare invasiva e causare perdita di biodiversità e cambiamenti nei servizi ecosistemici (Giakoumi 2014, Vergés et al. 2016). Nel Mediterraneo oggi sono presenti circa 1.000 NIS, delle quali 134 sono macroite (Verlaque et al. 2015, Alós et al. 2016). Per ridurre il rischio di future introduzioni e meglio comprendere il potenziale invasivo e le dinamiche di diffusione …
Spin Trapping of Carbon-Centered Ferrocenyl Radicals with Nitrosobenzene
2015
In contrast to metal centered 17 valence electron radicals, such as [Mn(CO)5]•, ferrocenium ions [Fe(C5H5)2]+ (1+), [Fe(C5Me5)2]+ (2+), [Fe(C5H5)(C5H4Et)]+ (3+), [Fe(C5H5)(C5H4NHC(O)Me)]+ (4+), and [Fe(C5H5)(C5H4NHC(S)Me)]+ (5+) do not add to nitrosobenzene PhNO to give metal-coordinated stable nitroxyl radicals. In the presence of the strong and oxidatively stable phosphazene base tert-butylimino-tris(dimethylamino)phosphorane, the quite acidic ferrocenium ions 1+–5+ are deprotonated to give a pool of transient and persistent radicals with different deprotonation sites [1–Hx]•–[5–Hx]•. One rather persistent iron-centered radical [4–HN]•, deprotonated at the nitrogen atom, has been detected…
Reactive surface coatings based on polysilsesquioxanes: universal method toward light-responsive surfaces.
2011
Reactive surface coatings were used as an ideal precursor coating for the fabrication of three different photoswitchable surface coatings in parallel. Different light-responsive moieties, such as azobenzene, salicylideneaniline, and spiropyran, were immobilized on glass, polycarbonate, and steel surfaces. Independent from the underlying substrate, wettability could be switched reversibly by UV irradiation. The maximum switching range was obtained after functionalization of the reactive coating with spiropyran, resulting in a contact angle difference between the two isomeric states of almost 30°.
Standardvarietäten in finnischen DaF- und EFL-Lehrwerken : Ein Vergleich zwischen Deutsch-Lehrwerken und Englisch-Lehrwerken
2010
Englanti ja saksa ovat kieliä, jotka ovat virallisia kieliä useammassa maassa eli niillä on useampi standardivarieteetti. Tällöin puhutaan kielen plurisentrisyydestä. Standardivarieteettien tunteminen on oleellinen osa kommunikatiivista kompetenssia ja oppilaan kielitaitoa. Tässä työssä tutkittiin, miten suomalaiset englannin ja saksan vieraankielen oppikirjat ottavat huomioon kielen plurisentrisyyden ja sen eri standardivarieteetit. Tavoitteena oli tutkia, millainen rooli kullakin standardivarieteetilla oppikirjassa on, missä järjestyksessä varieteetit tulevat opinpolulla esiin, mitä kielen aspekteja, esim. sanasto ja ääntäminen, oppikirjat standardivarieteeteista esittelevät. Tavoitteena …
Konsul’stvo Pol’ŝì v Odesì v 1918-1920 rr ta jogo arhìv
2017
General Consulate of the Republic of Poland established in Odessa in 2003 is the third Polish diplomatic mission in the Black Sea region of present — day Ukraine. The second Polish consulate, representing the reviving Polish statehood, functioned at the Black Sea between January 1919 and the beginning of February 1920, with almost a 5-month-long break, during the first Bolshevik occupation of Odessa. Zenon Belina Brzozowki was the consul in office during the period of January, 4, 1919 to March, 3, 1919 and then again since the end of August, (between April and August he stayed in Istanbul), in October and November, 1919 he was replaced by Stanisław Srokowski, a diplomat in the rank of I cla…
The chemical composition of the aerial parts of Stachys spreitzenhoferi (Lamiaceae) growing in Kythira Island (Greece), and their antioxidant, antimi…
2022
The Stachys L. genus has been used in traditional medicine to treat skin inflammations, stomach disorders, and stress. The aim of this study was to investigate the chemical profile and biological activity of the methanolic extract of Stachys spreitzenhoferi Heldr. (Lamiaceae) aerial parts, collected on the island of Kythira, South Greece. The analysis by liquid chromatography coupled with electrospray ionization and high-resolution mass spectrometry [LC-(-)ESI/HRMSn] of the methanol extract revealed the occurrence of thirty-six compounds - flavonoids, phenylethanoid glycosides, iridoids, quinic acid derivatives, aliphatic alcohol glycosides, and oligosaccharides - highlighting the substanti…
Przekształcenia struktur wieku ludności gmin województwa opolskiego wyznacznikiem dla lokalnych polityk społecznych
2018
Obserwowana w ostatnich latach zmiana struktury wieku ludności Polski, a szczególnie województwa opolskiego wykazuje systematyczny wzrost udziału osób starszych przy jednoczesnym spadku udziału ludności w najmłodszych grupach wiekowych, co skutkuje starzeniem się społeczeństwa. Wraz z przekształceniem struktury wieku następują zmiany w strukturze potrzeb ludności. Stąd też na poziomie lokalnym (powiatów i gmin) polityka społeczna w dużej mierze zdeterminowana jest przez przemiany demograficzne, jakie zachodzą na danym obszarze. Szczebel lokalny najbardziej jest predystynowany do zaspokojenia potrzeb w sposób uwzględniający lokalną specyfikę, znajomość struktury potrzeb i możliwości ich zasp…
Przestrzenne ograniczenie teatru wojny w kontekście praw i obowiązków państw neutralnych
2018
Współcześnie, tradycyjnie rozumiana kategoria państwa neutralnego uległa zmianie. Spowodowane jest to przede wszystkim ewolucją nietykalności terytorium państwa. Obecnie, tradycyjnie rozumiana nietykalność terytorialna państwa, wobec współczesnych, technicznych możliwości prowadzenia wojny musi, w sensie regulacji prawnomiędzynarodowych, ulec zmianie. Należy jednoznacznie stwierdzić, że dotychczasowa neutralność państwa jest li tylko kategorią historyczną
Transnational Struggle for Recognition: Axel Honneth on the Embodied Dignity of Stateless Persons
2021
In the last 15 years, scholars have increasingly applied Axel Honneth’s recognition theory to global issues such as justice, poverty, solidarity, peace, cosmopolitanism, and climate change. UNHCR estimates that there are currently 12 million stateless people worldwide. Their citizenship rights and human rights are mis-recognized. As humans, their human rights and human dignity should be protected. However, this requires being a citizen of a state, which, by definition, excludes stateless people. Although representing a fairly large group among today’s irregular migrants, within the above Honneth scholarship, statelessness is seldom investigated. And if being explored, the primary focus is r…
Zeno dynamics and high-temperature master equations beyond secular approximation
2013
Complete positivity of a class of maps generated by master equations derived beyond the secular approximation is discussed. The connection between such class of evolutions and physical properties of the system is analyzed in depth. It is also shown that under suitable hypotheses a Zeno dynamics can be induced because of the high temperature of the bath.
