Glen Philips: Western Australia's poet of the land and environment
2020
Artykuł ten nawiązuje do problematyki stosunkowo młodej gałęzi, jaka rozwinęła się w krytyce literackiej ostatnich dekad, tzw. ekokrytyki i jej obecności w literaturze australijskiej na przykładzie zachodnioaustralijskiego poety i krytyka Glena Philipsa (1936–), którego poezja jest ściśle związana ze środowiskiem naturalnym, w którym wzrastał i które zawsze inspirowało jego pisarstwo. Po skrótowym przedstawieniu historii ekokrytyki w USA, Europie i Australii autor, posługując się koncepcją pochodzenia dzieła sztuki niemieckiego filozofa Martina Heideggera, interpretuje wiersz Glena Philipsa pt. „In the Hollow of the Land”, widząc w nim egzemplifikację wspólnego rozumienia świata, jaki jest …

La lungimiranza politica di Claudio fra storiografia antica e Ragion di stato dei moderni
2018
Il contributo si concentra sul racconto tacitiano del discorso tenuto da Claudio nel 48 d.C. a favore dell’ammissione in senato dei primores della Gallia Comata, esaminando le argomentazioni usate dallo storico per chiarire le reazioni suscitate dalla loro richiesta e la linea argomentativa adottata dall’imperatore per convincere i senatori ad accettarla. Oltre ad esprimere la consapevolezza dell’efficacia dei criteri usati dai romani per istituire un ordinamento imperiale a carattere sopranazionale, il passo mostra l’abilità di Tacito nel sottolineare la pregnanza politica dell’intervento di Claudio e nel renderlo un modello meritevole di sopravvivere ed essere menzionato molti secoli più …
The boundary Harnack inequality for infinity harmonic functions in Lipschitz domains satisfying the interior ball condition
2008
Abstract In this note, we give a short proof for the boundary Harnack inequality for infinity harmonic functions in a Lipschitz domain satisfying the interior ball condition. Our argument relies on the use of quasiminima and the notion of comparison with cones.
Spectral analysis of the low-mass X-ray pulsar 4U 1822-371: Reflection component in a high-inclination system
2021
Context. The X-ray source 4U 1822-371 is an eclipsing low-mass X-ray binary and X-ray pulsar, hosting a NS that shows periodic pulsations in the X-ray band with a period of 0.59 s. The inclination angle of the system is so high (80–85°) that in principle, it should be hard to observe both the direct thermal emission of the central object and the reflection component of the spectrum because they are hidden by the outer edge of the accretion disc. Despite the number of studies carried out on this source, many aspects such as the geometry of the system, its luminosity, and its spectral features are still debated. Aims. Assuming that the source accretes at the Eddington limit, the analysis perf…
Detailed study of the X-ray and optical/UV orbital ephemeris of X1822-371
2011
Recent studies of the optical/UV and X-ray ephemerides of X1822-371 have found some discrepancies in the value of the orbital period derivative. Because of the importance of this value in constraining the system evolution, we comprehensively analyse all the available optical/UV/X eclipse times of this source to investigate the origin of these discrepancies. We collected all previously published X-ray eclipse times from 1977 to 2008, to which we added the eclipse time observed by Suzaku in 2006. This point is very important to cover the time gap between the last RXTE eclipse time (taken in 2003) and the most recent Chandra eclipse time (taken in 2008). Similarly we collected the optical/UV e…
New ephemeris of the ADC source 2A 1822-371: a stable orbital-period derivative over 30 years
2010
We report on a timing of the eclipse arrival times of the low mass X-ray binary and X-ray pulsar 2A 1822-371 performed using all available observations of the Proportional Counter Array on board the Rossi X-ray Timing Explorer, XMM-Newton pn, and Chandra. These observations span the years from 1996 to 2008. Combining these eclipse arrival time measurements with those already available covering the period from 1977 to 1996, we obtain an orbital solution valid for more than thirty years. The time delays calculated with respect to a constant orbital period model show a clear parabolic trend, implying that the orbital period in this source constantly increases with time at a rate $\dot P_orb = …
Solipsismin kritiikki Wittgensteinin myöhäisfilosofiassa
2007
Tässä tutkielmassa käsittelen solipsismin teemaa Ludwig Wittgensteinin myöhäiskauden filosofiassa. Tavoitteena on tarkastella huolellisesti Wittgensteinin solipsismiin liittyviä tekstikokonaisuuksia ja huomautuksia ja selvittää, kuinka näiden kautta hahmottuu moniosainen ja voimakas kritiikki solipsismia vastaan. Esitän, että Wittgensteinin kriittiset argumentit kehittyivät hänen käytyään 1930-luvun alussa ajattelussaan läpi metodologisen solipsismin vaiheen; esitän myös, että Wittgensteinin solipsismin kritiikki pohjautui ”minän” ja ”aistimuksen” käsitteiden kieliopilliseen tarkasteluun; ja että hän tulkitsi metafyysisen solipsismin lähteeksi taipumuksen käyttää tiettyjä käsitteitä irrotet…
Thermo-optical studies of NaNbO3thin films
2007
Thermo-optical studies of sodium niobate NaNbO3 (NN) thin films, deposited by the pulsed laser ablation technique on Si/SrRuO3 substrates, were performed by spectroscopic ellipsometry in the temperature range 300-550°C. Optical constants at the room temperature were measured in the spectral range 250-1000 nm. Substantial changes in the refractive index temperature behaviour (taken at λ = 300 nm) were found at temperatures 370, 445, 503, 520, and 532°C, where the first and the last temperatures are the phase transitions P → R and S → T1, respectively. Other temperatures (445, 503, and 520°C) are suggested as the points of some local structural changes in the NN film.
