LE INDAGINI BANCARIE - CONTRIBUTO ALLO STUDIO DELLE PRESUNZIONI NEL DIRITTO TRIBUTARIO
2009
La monografia in esame affronta la questione delle presunzioni bancarie inserendole nel più ampio studio delle presunzioni nella materia tributaria. La prima parte riguarda l'evoluzione storica che ha progressivamente condotto all'abbandono del segreto bancario ed all'introduzione delle presunzioni legali relative in materia bancaria. La seconda parte riguarda lo studio comparato delle presunzioni nei sistemi civili, penali e tributari e l'inquadramneto delle presunzioni bancarie nel novero delle presunzioni legali relative. La terza parte riguarda i profili critici della normativa e le ragioni che dovrebbero condurre ad una sua abrogazione, unitamente ad un opzione esegetica che potrebbe c…
La longue durée du scandale: l'Affaire Montesi entre vérité et fiction
2014
Il saggio ripercorre la storia di un celebre fatto di cronaca nera, divenuto scandalo internazionale, il caso Montesi, ne considera la ricezione giornalistica e saggistica in Italia e all'estero, ed esamina alcune delle sue principali elaborazione narrative, al confine tra fiction e non fiction. The essay reconstructs a fait divers which became an international scandal, the Montesi Affair, dealing with its journalistic reception and with its main literary representations, on the edge between fiction and non fiction.
Effect of Pulsed Electric Field Pretreatment on Drying Kinetics, Color, and Texture of Parsnip and Carrot.
2018
The aim of the study was to evaluate the effect of pulsed electric field (PEF) pretreatment on drying kinetics and on color and textural changes in sliced parsnip and carrot. Cell disintegration index measured in parsnips after PEF pretreatment significantly differed from the ones measured for carrots and, consequently, the reduction of the time needed to dry both samples to a final moisture content up to 5% (wet basis). The drying time of the PEF pretreated parsnip was reduced by up to 28% at 70 °C and by up to 21% at 60 °C in carrot, in comparison to untreated samples. The PEF pretreatment influenced the effective diffusivity of water into the samples going from 50 °C to 70 °C: in carrots…
Arquitectura renacentista "inacabada" de Jerónimo Quijano y su integración en determinados templos de origen gòtico
2014
Jerónimo Quijano fue un arquitecto español que destacó durante la etapa del Renacimiento Pleno en España en el tercio central del siglo XVI. Los edificios seleccionados principalmente son: iglesia de Santiago de Orihuela –Alicante– e iglesia de Santa María del Salvador de Chinchilla –Albacete–. En ambos se construyó una nueva cabecera renacentista e integrada en una nave gótica preexistente y en el caso de haber sido “acabadas” íntegramente con el criterio del maestro serían sin duda ejemplos claves del Renacimiento español. En Orihuela se percibe la necesidad de “descubrir” visualmente el magnífico arco de triunfo romano que hace de portada de la nueva cabecera renacentista, sugiriendo así…
Domain shuffling between Vip3Aa and Vip3Ca: chimera stability and insecticidal activity against European, American, African, and Asian pests
2020
The bacterium Bacillus thuringiensis produces insecticidal Vip3 proteins during the vegetative growth phase with activity against several lepidopteran pests. To date, three different Vip3 protein families have been identified based on sequence identity: Vip3A, Vip3B, and Vip3C. In this study, we report the construction of chimeras by exchanging domains between Vip3Aa and Vip3Ca, two proteins with marked specificity differences against lepidopteran pests. We found that some domain combinations made proteins insoluble or prone to degradation by trypsin as most abundant insect gut protease. The soluble and trypsin-stable chimeras, along with the parental proteins Vip3Aa and Vip3Ca, were tested…
Missione archeologica in Libia dell’Università degli Studi di Palermo; Nicola Bonacasa
2021
The paper contains a brief survey of the activities and objectives of the Archaeological Mission of Palermo University in Libya and a profile of Nicola Bonacasa, who led the Mission for forty years (1976-2015).
A New Systematic Series of Foil Sections with Parallel Sides
2020
Parallel-sided foil sections are used for centerboards and rudders in sailing dinghy classes and also for struts placed in a fluid flow. The objective of this work is to create a systematic series of parallel-sided sections to be used under different conditions, with an emphasis on the sailing dinghies 470, 420 and Optimist. The loss, and surprisingly the gain, in performance relative to 4-digit NACA sections are also investigated. A 2D Reynolds-averaged Navier&ndash
Le ricerche in Libia
2016
Si prende in esame l'attività svolta dal prof. Bonacasa in Libia, dalle prime ricerche all'avvio della Missione dell'allora Istituto di Archeologia dell'Università di Palermo (Leptis Magna, Sabratha, Cirene), evidenziandone gli obiettivi e i risultati.
Comparison of essential oil components and in vitro anticancer activity in wild and cultivated Salvia verbenaca.
2015
The objectives of our research were to study the chemical composition and the in vitro anticancer effect of the essential oil of Salvia verbenaca growing in natural sites in comparison with those of cultivated (Sc) plants. The oil from wild (Sw) S. verbenaca presented hexadecanoic acid (23.1%) as the main constituent, while the oil from Sc plants contained high quantities of hexahydrofarnesyl acetone (9.7%), scarce in the natural oil (0.7%). The growth-inhibitory and proapoptotic effects of the essential oils from Sw and Sc S. verbenaca were evaluated in the human melanoma cell line M14, testing cell vitality, cell membrane integrity, genomic DNA fragmentation and caspase-3 activity. Both t…
A new ceramide from the leaves of Lannea schimperi (Hochst. ex A.Rich.) Engl.
2020
A new ceramide is being reported herein together with six known compounds from the methanol extract of the leaves of Lannea schimperi (Hochst. ex A.Rich.) Engl. The metabolites were obtained through repeated open column chromatography and were characterized by spectroscopic and spectrometric techniques. The radical-scavenging activity of the crude extract and isolated compounds was evaluated using the DPPH radical. The obtained results suggest the studied species as prominent candidate to fight reactive oxygen species (ROS).
