«INTELLIGENTE, IRONICA». OLTRE IL MATRIARCATO, LA DONNA IN ALCUNE OPERE DI LEONARDO SCIASCIA
2021
Intelligente e ironica. Così appare al pittore protagonista del romanzo Todo modo la donna che lascia il marito nello spiazzale antistante L’Eremo di Zafer. Il tempo di uno sguardo, di una breve sequenza. Tuttavia il suo rilievo espressivo travalica la pagina per andare, insieme a tanti piccoli tasselli narrativi di altri racconti, a comporre un’inedita rappresentazione del personaggio femminile. E ciò assume un significato particolare se facciamo attenzione per un momento alle date, se consideriamo per esempio che l’anno di pubblicazione di Todo modo è lo stesso 1974 in cui lo scrittore rilascia la famosa intervista a Franca Leosini che tanto scandalo ha suscitato soprattutto fra le fem…
La tutela del Patrimonio Storico e Artistico d’interesse religioso nelle autonomie speciali. Due esempi a confronto: Sicilia e Catalogna
2010
Partendo dall’analisi delle caratteristiche comuni al regionalismo c.d. “asimmetrico” italiano e spagnolo, il saggio si propone di utilizzare il paradigma offerto, rispettivamente, dal modello siciliano e catalano, per studiarne l’incidenza sulla regolamentazione e gestione dei beni culturali d’interesse religioso, sia unilaterale sia concertata con le autorità ecclesiastiche. L’obiettivo primario è di fare emergere, attraverso il confronto dei rispettivi regimi, gli elementi di specialità che sono riscontrabili nell’organizzazione del settore e nella relativa disciplina, a causa dell’autonomia differenziata che contraddistingue i due enti regionali; con una particolare attenzione a quelli …
A techno-economic comparison of biogas upgrading technologies in Europe
2012
Biokaasua voidaan hyödyntää lämmön- ja energiantuotannon polttoaineena tai puhdistaa ja jalostaa käytettäväksi esimerkiksi ajoneuvojen polttoaineena . Prosessissa vapautuvaa hiilidioksidia voidaan hyödyntää teollisuudessa. Euroopassa käytettävät pääasialliset biokaasun jalostustekniikat ovat PSA (Pressure Swing Adsorption) sekä vesipesu (Water Scrubbing). Tämän työn ensimmäinen tavoite on vertailla pienten, keskisuurten sekä suurten biokaasun jalostuslaitosten taloudellisuutta Euroopassa. Toinen tavoite on arvioida pienten biokaasulaitosten teknisiä mahdollisuuksia Euroopassa. Tutkimusmenetelmänä on käytetty kyselylomaketta, joka on lähetetty biokaasulaitosten omistajille/operoijille. Kysel…
Survey of the parasitoids of the European Sunflower MothHomoeosoma nebulella [Lep.: Pyralidae] in the palearctic region
1993
The European Sunflower MothHomoeosoma nebulella Denis & Schiffermuller is a potential pest on sunflower in France. The parasitoids of this moth are little known. We present here original data obtained in the south of France together with previous survey. Some parasitoids we found were new records onH. nebulella. The relative weakness of the parasite complex ofH. nebulella (less than 15 species) compared to that of the American Sunflower MothH. electellum (Hulst) is discussed.
Novel Developments on Artemisinin and Its Derivatives for Cancer Therapy
2009
The lack of effective long-term anticancer therapy highlights the necessity to identify new potent anticancer compounds. Many biocompounds of naturally occurring medicinal plants have pharmacological activities and, thus, represent a source of molecules that may have anti-proliferative effects on a variety of cancers. During the past 10 years, we have systematically analyzed medicinal plants used in traditional Chinese medicine and focused our interest on Artemisia annua (sweet wormwood herb). The active principle of sweet wormwood herb is Artemisinin, a sesquiterpene, which exerts not only anti-malarial activity but also profound cytotoxicity against tumour cells. The anti-tumour mechanism…
Zilās gaismas draudu kumulatīvā analīze
2022
Maģistra darbs uzrakstīts angļu valodā uz 42 lappusēm. Tas satur 15 attēlus, 4 vienadojumi, 8 tabulas un 64 atsauces. Cilvēki katru dienu ir pakļauti zilajai gaismai. Zilā gaisma ir bīstama, ja tā pārsniedz 100 J / (cm2-sr) uz 106 ≤ t. Pirmsreceptoru makulas pigmenti, luteīns un zeaksantīns kopā ar lēcas kristālu absorbē zilo gaismu. Zilās gaismas svērtais spožums dažādos ekspozīcijas ilgumos tika modelēts ar doto datu bāzi, kas ņemta no f. fluxometrs dažādiem zilās gaismas avotiem. Rezultāti parādīja, ka gaismai, ko izstaro saules gaisma, īpaši saulainās dienās, ir visaugstākās zilās gaismas spožuma vērtības un tā tiek uzskatīta par kaitīgu, bet tomēr nepārsniedz vērtības, kas pierāda bīst…
Masonry structures subjected to tsunami loads: Modeling issues and application to a case study
2020
Abstract Tsunamis are among the most dangerous natural disasters for coastal areas experiencing tsunami hazard. One of the major concerns in the assessment of strategies for the risk mitigation is to estimate vulnerability of structures and infrastructures. However, reliable approaches for the evaluation of the structural capacity under tsunami loads are nowadays not always available for all the types of structures, especially masonry. On this aim, the paper deals with the modeling issues of 3D masonry structures subjected to tsunami loads and the effect on the structural behavior of different modeling approaches. First, a brief state of the art on the available studies is presented regardi…
FoSBaS: A bi-directional secrecy and collusion resilience key management scheme for BANs
2012
Body Area Network (BAN) consists of various types of small physiological sensors, transmission modules and low computational components and can thus form an E-health solution for continuous all-day and any-place health monitoring. To protect confidentiality of collected data, a shared group key is usually deployed in a BAN, and consequently a secure communication group is generated. In this paper, we propose a bi-directional security and collusion resilience key management scheme for BAN, referred to as FoSBaS. Detailed analysis shows that the scheme can provide both forward security and backward security and resist against collusion attacks. Furthermore, the FoSBaS is implemented on a Sun …
SCARKER: A sensor capture resistance and key refreshing scheme for mobile WSNs
2011
How to discover a captured node and to resist node capture attack is a challenging task in Wireless Sensor Networks (WSNs). In this paper, we propose a node capture resistance and key refreshing scheme for mobile WSNs which is based on the Chinese remainder theorem. The scheme is able of providing forward secrecy, backward secrecy and collusion resistance for diminishing the effects of capture attacks. By implementing our scheme on a Sun SPOT based sensor network testbed, we demonstrate that the time for updating a new group key varies from 56 ms to 546 ms and the energy consumption is limited to 16.5–225 mJ, depending on the length of secret keys and the number of sensors in a group.
