Architetture dell'industria del cinema in Sicilia
2022
L'interesse del popolo siciliano per il cinema e l'arte cinematografica si manifesta alla fine del XIX secolo quando, nel capoluogo siciliano viene presentato il Kinetoscopio Edison. Una macchina che permetteva di vedere una figura in movimento accostando l'occhio sulla lente di un meccanismo all'interno del quale girava la pellicola. L'anno successivo, il primo spettacolo di Kinefotografo segna l'inizio delle proiezioni di immagini in movimento su uno schermo. L'evento è seguito dall'arrivo del Cinematografo Lumière che sostituisce le proiezioni itineranti allestite nelle piazze, dando impulso alla nascita di sale di proiezione e, successivamente, a impianti architettonici adeguati ad un p…
Dubbi vecchi e nuovi dinanzi ai recenti "pacchetti sicurezza"
2010
Il saggio si sofferma sulle novità introdotte dalle leggi n.94/2009 e n.125/2008 in materia di legislazione antimafia con precipuo riferimento ai profili civilistici concernenti il regime giuridico degli atti di disposizione e gli effetti patrimoniali delle misure di prevenzione.
Thermal stability of trimeric light-harvesting chlorophyll a/b complex (LHCIIb) in liposomes of thylakoid lipids.
2006
The major light-harvesting chlorophyll a/b complex (LHCIIb) of photosystem (PS) II functions by harvesting light energy and by limiting and balancing the energy flow directed towards the PSI and PSII reaction centers. The complex is predominantly trimeric; however, the monomeric form may play a role in one or several of the regulatory functions of LHCIIb. In this work the dissociation temperature was measured of trimeric LHCIIb isolated from Pisum thylakoids and inserted into liposomes made of various combinations of thylakoid lipids at various protein densities. Dissociation was measured by monitoring a trimer-specific circular dichroism signal in the visible range. The LHCIIb density in t…
Separation, isolation and stereochemical assignment of imazalil enantiomers and their quantitation in an in vitro toxicity test
2016
A simple method for the separation of the enantiomers of the fungicide imazalil was developed. Racemic imazalil was separated into its enantiomers with an enantiomeric purity of 99% using HPLC-UV with an enantioselective column (permethylated cyclodextrin) operated in reversed phase mode (water with 0.2% trimethylamine and 0.08% acetic acid and methanol). The absolute configuration of the separated enantiomers was assigned and unequivocally confirmed by optical rotation as well as by vibrational circular dichroism (VCD) and electronic circular dichroism (ECD) combined with ab-initio calculations. The same enantioselective column was also used to develop an HPLC-MS/MS method for the quantifi…
Conflitti tra azioni esecutive civili e sequestri disposti dal giudice penale
2016
Lo scritto esamina le conseguenza prodotte dai sequestri penali sul patrimonio responsabile del debitore, al fine di approfondire la posizione dei creditori, che vorrebbero sui beni oggetto di sequestro penale. The essay deal with the consequences of penal freezing of the debtor's asset, with regard of the creditors' right to seize the debtor's assets to satisfy their rights.
Weaving words for textile museums: the development of the linked SILKNOW thesaurus.
2022
Abstract The cultural heritage domain in general and silk textiles, in particular, are characterized by large, rich and heterogeneous data sets. Silk heritage vocabulary comes from multiple sources that have been mixed up across time and space. This has led to the use of different terminology in specialized organizations in order to describe their artefacts. This makes data interoperability between independent catalogues very difficult. To address these issues, SILKNOW created a multilingual thesaurus related to silk textiles. It was carried out by experts in textile terminology and art historians and computationally implemented by experts in text mining, multi-/cross-linguality and semanti…
The application of phospholipid removal columns and ultra-high performance liquid chromatography-tandem quadrupole mass spectrometry for quantificati…
2016
In this study a robust and sensitive method based on a proposed sample purification procedure, using zirconia-coated Phree™ columns and analysis by ultra-high performance liquid chromatography with triple quadrupole tandem mass spectrometry are presented for the assessment of multi-class antibiotics in farmed fish species. The sample preparation procedure benefited from combined precipitation of proteins and selective removal of phospholipids by Phree™ columns, resulting in a high sensitivity of the method (LOQ 0.3-9mgkg(-1)). The in-house validation results (precision, repeatability, decision limit CCα, detection capability CCβ, etc.) indicate that the elaborated method is fully suitable f…
Comparison of several methods used for the determination of cephalosporins. Analysis of cephalexin in pharmaceutical samples
2002
The precision of UV absorbance of intact and acid degraded cephalosporins, ninhydrin, high performance liquid chromatography and iodometric methods used for analysis of cefoxitin, cefotaxime, cephazolin and cephalexin were compared. To obtain the calibration graphs the analytical signal used were: absorbance, first derivative absorbance, second derivative absorbance and H-point Standard Additions Method by using absorbance values at two selected wavelengths as analytical signal. These methods and calibration graphs were also used for the determination of cephalexin in pharmaceutical samples.
