Incomplete retention of radiation damage in zircon from Sri Lanka
2004
A suite of 18 zircon gemstones from placers in the Highland/Southwestern Complex, Sri Lanka, were subjected to a comprehensive study of their radiation damages and ages. The investigation included X-ray diffraction, Raman and PL spectroscopy, electron microprobe, PIXE and HRTEM analysis, as well as (U-Th)/He and SHRIMP U-Th-Pb age determinations. Zircon samples described in this study are virtually homogeneous. They cover the range from slightly metamict to nearly amorphous. Generally concordant U-Th-Pb ages averaging 555 ± 11 Ma were obtained. Late Ordovician zircon (U-Th)/He ages scattering around 443 ± 9 Ma correspond reasonably well with previously determined biotite Rb-Sr ages for rock…

Zircon M257 - a homogeneous natural reference material for the ion microprobe U-Pb analysis of zircon
2008
We introduce and propose zircon M257 as a future reference material for the determination of zircon U-Pb ages by means of secondary ion mass spectrometry. This light brownish, flawless, cut gemstone specimen from Sri Lanka weighed 5.14 g (25.7 carats). Zircon M257 has TIMS-determined, mean isotopic ratios (2s uncertainties) of 0.09100 ± 0.00003 for 206pb/238U and 0.7392 ± 0.0003 for 207pb/235U. Its 206pb/238U age is 561.3 ± 0.3 Ma (unweighted mean, uncertainty quoted at the 95% confidence level); the U-Pb system is concordant within uncertainty of decay constants. Zircon M257 contains ∼ 840 μg g−1 U (Th/U ∼ 0.27). The material exhibits remarkably low heterogeneity, with a virtual absence of…
Tuhoisa influentsa tarttui leskipastorska Pihlin kotikirjastoon: pandemian vaikutus 1800-luvun perheen kirjakokoelmaan
2023
1800-luvulla kirjoilla oli esineinä vielä rahallista ja yhteiskunnalliseen statukseen liittyvää arvoa, ja omistajan kuolema aloitti yleensä vain uuden luvun kirjan elämässä. Tutkin kuolinpesien kirjakokoelmien kohtaloja käyttämällä esimerkkinä erästä 1800-luvun lopun tapausta, jossa leskipastorska Pihl antoi kotikirjastonsa kirjoja helsinkiläiselle Minerva-antikvariaatille myytäväksi. Mikrohistoriallinen esimerkki kertoo perheenjäsenen kuolemantapauksen vaikutuksesta eri sukupuolten ja sukupolvien kirjanomistukseen. Tarkastelen, miten säätyläisperheissä, kuten pappisperheissä, yhtäkkinen kuolema muutti kirjojen omistussuhteita, ja kuinka perheen sisällä miesten ja naisten suhtautuminen kirj…

Typhoid fever as a cause of opportunistic infection: case report.
2005
Abstract Background Typhoid fever is a systemic infection caused by the bacterium Salmonella enterica subspecies enterica serotype typhi, which is acquired by ingestion of contaminated food and water. Each year the disease affects at least 16 million persons world-wide, most of whom reside in the developing countries of Southeast Asia and Africa. In Italy the disease is uncommon with a greater number of cases in Southern regions than in Northern ones. Case presentation We report on a 57-year-old Sri-Lankan male affected by typhoid fever, the onset of which was accompanied by oropharyngeal candidiasis. This clinical sign was due to a transient cell-mediated immunity depression (CD4+ cell cou…
Lo Sri Lanka e il conflitto etnico fra tamil e singalesi
2010
Il contributo ha lo scopo di porre l''attenzione su uno dei conflitti etnici più interessanti e di cui però i media discutono poco: quello tra Tamil e Singalesi nello Sri Lanka. Si tratta di un conflitto di cui si individuano le origini antichissime e le fasi di sviluppo, fino ai recenti avvenimenti che hanno determinato, negli ultimi decenni, decine di migliaia di morti e una migrazione senza precedenti. Il risultato a cui si perviene è originale in quanto si dimostra che entrambi i gruppi etnici hanno ragione nell''asserire il loro diritto di originaria presenza sul territorio. Da qui lo sviluppo di alcune ipotesi di risoluzione del conflitto.
Two solitudes: Singalesi e Tamil tra Catania e Palermo
2012
Immigrants from Sri Lanka in Sicily are the prevailing representatives of the Indian Subcontinent. Their migration took place with the beginning of the ethnic conflict which started in 1983. The two communities, Sinhalese and Tamils, decided to settle respectively in Catania and Palermo proposing the same distrust of the conflict. So the “two solitudes” of the two major Sicilian cities are also the mirror of the lack of communication of the two ethnic groups of Sri Lanka.
Il declino delle destinazioni turistiche
2015
Il saggio, partendo dal noto ciclo di vita delle destinazioni turistiche elaborato da Richard Butler nel 1980, riflette sul destino turistico e sulle potenzialità di territori ancora oggi percepiti come pericolosi (Iraq, Sri Lanka, Vietnam). The essay, starting from the well-known life cycle of tourist destinations elaborated by Richard Butler in 1980, reflects on the tourist destiny and on the potential of territories still today perceived as dangerous (Iraq, Sri Lanka, Vietnam).
Cuando la violencia genera identidad. La guerra en Sri Lanka y la diáspora tamil en Sicilia
2011
Sri Lanka, durante las dos últimas décadas, fue el escenario de una prolongada guerra civil entre la mayoría cingalesa budista y la minoría tamil hindú, que ha defendido su independencia. La primera parte de este artículo muestra que no fueron las diferencias de origen étnico-cultural las que llevaron a la guerra, sino las razones políticas y económicas. La guerra civil ha llevado a una radicalización y cristalización de las diferencias étnicas a través de la manipulación del pasado y del papel político del budismo. La guerra provocó la diáspora tamil en todo el mundo, incluyendo también Sicilia. En la segunda parte del artículo, se presentan algunos puntos del trabajo de campo realizado co…
