Assessment of bacterial and fungal (hemi)cellulose-degrading enzymes in saccharification of ammonia fibre expansion-pretreated Arundo donax
No full textThis study reports enzymatic hydrolysis of the biomass of the giant reed (Arundo donax L.) after ammonia fibre expansion (AFEX) pretreatment. In particular, the capacity of the arabinofuranosidase from the fungus Pleurotus ostreatus recombinantly expressed in Pichia pastoris rPoAbf, its evolved mutant rPoAbf F435Y/Y446F and the endo-cellulase from Streptomyces sp. G12 CelStrep recombinantly expressed in Escherichia coli to enhance the hydrolysis of AFEX-treated A. donax was investigated, using the corn stover as reference feedstock. The investigated enzymes were assayed using a mixture of purified cellulases (CBHI, CBHII, EGI and βG), endoxylanases (LX3, LX4) and accessory hemicellulases (LarbF and LβX) as reference enzyme mixture and substituting EGI with rCelStrep and LarbF with rPoAbf or rPoAbf F435Y/Y446F. The use of rPoAbf F435Y/Y446F in the substitution of LarbF led to improvements in sugar conversion, giving a glucan, xylan and arabinan conversion after 72 h of around 62, 63 and 80 %, respectively, similar or higher than those (44, 66 and 55 %) achieved by 72 h hydrolysis with commercial enzymes Novozymes Cellic®, Ctec3 and Htec3. The enzymes rPoAbf, rPoAbf F435Y/Y446F and rCelStrep were also investigated for their effect on hydrolysis of AFEX-pretreated A. donax by addition to commercial enzyme mixture Novozymes Cellic®, Ctec3 and Htec3, and it was shown that the addition of rPoAbf and its evolved mutant rPoAbf F435Y/Y446F enhanced both xylan and arabinan conversions, which achieved 80 % after 6 days of saccharification with rPoAbf F435Y/Y446F
Boccaccio nel Seicento: censure e recuperi della "compassione"
No full textSIMONA MORANDO, Boccaccio in the sixteenth century: censorship and recovery ofthe «compassion»
In the introduction of this paper, the literature of the seventeenth century is defined as a writing of compassion but not of consolation (quotations from Giovanni Cisano, Torquato Accetto, Emanuele Tesauro, G. B. Marino). The distance between the
writers studied here and Boccaccio is due to the censored editions of the Decameron in sixteenth century, to the censorship of Boccaccio as a «maestro d’amore», to his unrefined language, to his interpretation by many critics as a light and burlesque author. But, as reported in a writing by Boccalini, Boccaccio’s Latin works are very much appreciated in seventeenth century literature. This is especially the case of De casibus virorum illustrium, a gloomy and pessimistic book about misfortunes of famous men and about compassion, which nevertheless believes in the ability of letters to give back fame to ruined men. As shown in the conclusion
through some writings by Tassoni, many other seventeenth century authors do not have this kind of hope
Saccharification of newspaper waste after ammonia fiber expansion or extractive ammonia
No full textThe lignocellulosic fractions of municipal solid waste (MSW) can be used as renewable resources due to the widespread availability, predictable and low pricing and suitability for most conversion technologies. In particular, after the typical paper recycling loop, the newspaper waste (NW) could be further valorized as feedstock in biorefinering industry since it still contains up to 70 % polysaccharides. In this study, two different physicochemical methods—ammonia fiber expansion (AFEX) and extractive ammonia (EA) were tested for the pretraetment of NW. Furthermore, based on the previously demonstrated ability of the recombinant enzymes endocellulase rCelStrep, α-l-arabinofuranosidase rPoAbf and its evolved variant rPoAbf F435Y/Y446F to improve the saccharification of different lignocellulosic pretreated biomasses (such as corn stover and Arundo donax), in this study these enzymes were tested for the hydrolysis of pretreated NW, with the aim of valorizing the lignocellulosic fractions of the MSW. In particular, a mixture of purified enzymes containing cellulases, xylanases and accessory hemicellulases, was chosen as reference mix and rCelStrep and rPoAbf or its variant were replaced to EGI and Larb. The results showed that these enzymatic mixes are not suitable for the hydrolysis of NW after AFEX or EA pretreatment. On the other hand, when the enzymes rCelStrep, rPoAbf and rPoAbf F435Y/Y446F were tested for their effect in hydrolysis of pretreated NW by addition to a commercial enzyme mixture, it was shown that the total polysaccharides conversion yield reached 37.32 % for AFEX pretreated NW by adding rPoAbf to the mix whilst the maximum sugars conversion yield for EA pretreated NW was achieved 40.80 % by adding rCelStrep. The maximum glucan conversion yield obtained (45.61 % for EA pretreated NW by adding rCelStrep to the commercial mix) is higher than or comparable to those reported in recent manuscripts adopting hydrolysis conditions similar to those used in this study
Le chiavi del Paradiso. Primato petrino e devozione mariana di Sisto IV tra Cappella Sistina e S. Maria della Pace
No full textIl volume è strutturato in due parti distinte con una postfazione, un indice dei nomi e n. 55 Tavole a colori fuori testo, valide per entrambe le parti del volume. I. PARTE (di Lorenzo Cappelletti) A partire dalla esplicita indicazione che l’ignoto architetto, collocato sul fianco destro dell’affresco sistino della Consegna delle chiavi di Perugino, fa dell’edificio a pianta centrale che campeggia sullo sfondo, viene operata una completa rilettura iconografica e iconologica dell’intero affresco. Tenendo conto di tutta la migliore bibliografia sul tema e grazie anche alla considerazione di fonti inedite o mai considerate in relazione a tale affresco –– vengono riletti in particolare i due episodi evangelici sullo sfondo, la teoria dei dodici apostoli e dei personaggi dell’attualità di fine Quattrocento e soprattutto il gesto della consegna delle chiavi a Simon Pietro da parte di Gesù.
La rilettura si allarga necessariamente anche alla Punizione di Core, Datan e Abiram, l’affresco di Botticelli posto in chiave tipologica dirimpetto alla Consegna delle chiavi, e alla serie dei 30/32 papi affrescati nel cleristorio.
Lo studio non manca di offrire inoltre spunti per una comprensione più adeguata anche degli altri affreschi quattrocenteschi della sistina. II PARTE (di Simona Benedetti) Nell’ambito della revisione di lettura iconologica e iconografica dell’affresco della Consegna delle chiavi di Perugino nella Cappella Sistina, svolta da Lorenzo Cappelletti, si torna a riflettere anche sul significato dell’architettura dell’edificio rappresentato al centro dell’affresco. In questo senso nel contributo di Simona Benedetti, in primo luogo, si ripercorrono i riferimenti alla trattatistica quattrocentesca in materia di edifici sacri, che possono aver influito nella determinazione dell’edificio ottagonale.
In seconda istanza, si considerano le principali fabbriche a pianta ottagonale costruite precedentemente all’edificio dipinto, che possono aver costituito un fondato riferimento per il Perugino nella Consegna delle chiavi.
In particolare tra le architetture, che possono avere avuto un’influenza determinante nella definizione iconografica della fabbrica ottagonale presente nell'affresco, la chiesa di S. Maria della Pace è quella su cui si concentra il presente studio. L'opera si realizzò nel cuore pulsante della Roma rinascimentale proprio contemporaneamente all’affresco in esame, con esso trova degli innegabili punti di tangenza e corrispondenze, sia storiche che figurative. A questo riguardo interessantissima risulta la connessione tra il motivo dell’edificazione della fabbrica e i fatti storici, i personaggi, gli eventi prodigiosi e le pratiche devozionali, che condizionarono lo svolgersi del cantiere del Templum Pacis negli ultimi anni del pontificato di Sisto IV. La storicità del gesto della consegna delle chiavi a Pietro - avvenimento che si protrae nel tempo ad ogni elezione pontificia nello spazio fisico della Cappella Sistina - costituisce la centralità del messaggio iconografico dell'affresco del Perugino in cui, anche l’architettura, insieme ai personaggi rappresentati, strutturano una narrazione reale, estranea alle simbologie decontestualizzate dall’epoca propriamente sistina. Segue una postfazione di Francesco Andreani dal titolo Enigma del Quattrocento, saggio nel quale si sviluppano considerazioni sulle personalità degli architetti e maestranze attive nella Roma del tardo Quattrocento e negli anni di inizio della fabbrica di S. Maria della Pace. Il volume si conclude con l'indice dei nomi (a cura di Gemma Fusciello)I (of Lorenzo Cappelletti) Starting from the unknown architect’s forefinger pointed to the central plan building found in the background of the Sistine Perugino’s fresco The Keys of the Kingdom of Heaven, the author offers a new interpretation of the entire fresco at both an iconographical and iconological level.
Having considered the most important studies about this fresco and taking into account a number of unpublished and unconsidered sources, the author rereads in particular the meaning of the central plan building, as well as the two Gospel episodes in the background; and he rereads also the grouping of the Twelve, along with the fifteenth century historical personages painted among them, in the foreground.
The author’s vision necessarily broodens also to comprehend Botticelli’s fresco named The Punishment of Corah, Dathan and Abiram which is placed on the opposite wall as a typological prefiguration of The Keys of the Kingdom of Heaven; and it broodens moreover to reconsider the series of 30/32 popes frescoed in the upper register of the Sistine Chapel.
The essay also offers hints for a more complete comprehension of the other fifteenth century frescoes of the Sistine Chapel.
II. (of Simona Benedetti) As part of the review of iconological and iconographic reading about the fresco of the “Delivery of the keys” by Perugino in the Sistine Chapel, conducted by Lorenzo Cappelletti, you go back and think about the significance of the building architecture depicted in the center of the fresco. In this sense, the contribution of Simona Benedetti, first, retraces the references to the fifteenth-century treatises concerning sacred buildings, which may have affected the determination of the octagonal building. Secondly, we consider the main factories octagonal building constructed previously painted, that may have been an established reference for the Perugino in the “Delivery of the keys”. Especially between architectures, which may have had a decisive influence in defining the iconographic factory octagonal present in the fresco, the church of St. Mary of Peace is the one on which this study focuses. The work was realized in the heart of Renaissance Rome just simultaneously fresco concerned, although it is undeniable points of contact and correspondence, both historical and figurative. In this regard are interesting connections between the reason of building the factory, the historical facts, the characters and the miraculous events and devotional, which has conditioned the unfolding of the construction site of the Templum Pacis in the last years of the pontificate of Sixtus IV. The historicity of the act of handing over the keys to Peter, that continues over time in the physical space of the Sistine Chapel, is the centrality of the iconographic message of the fresco by Perugino; so even the architecture, along with the characters represented, the real narrative structure, far from to the symbolism belonging to the Sistine period properly
Playing with autism. Encountering Simona Concaro by her music. Vol. 1.1
No full textPlaying with Autism contains twenty-four original pieces for piano, recorded and carefully transcribed in current music notation by Pierluigi Politi and Hanna Shybayeva. Simona Concaro, the author, is a young woman suffering of low-functioning autism. She lives in Cascina Rossago, a farm-community, designed to meet the needs of people with autism, in Oltrepo pavese (Italy).
Since she was three, Simona Concaro has created original compositions on piano, instrument she learned by herself, refusing any kind of musical education. In everyday life, Simona does not use verbal language and has low autonomy. Her music, on the contrary, contains interesting features – melodic, rhythmic and harmonic –, even in the presence of some iterative elements, typical of the autistic spectrum
Global Sourcing of Services: How Well Are the New EU Member States Coping with the Challenges? (Part II)
No full textIn the current debate on services offshoring, the New EU member states (NMS) have focused increasingly the attention of economists and politicians, as well as the public at large. Particularly in the light of the recent waves of EU enlargement these countries have been considered as highly attractive locations for offshored services both from a European and global perspective. While a fairly large amount of anecdotal evidence documents the NMS high potentialities in terms of services offshoring, academic research on this topic is limited. This paper aims to contribute to this discussion. Drawing on recent literature on the complex issue of services globalisation, the paper investigates NMS trade and FDI flows in services over the 1995-2007 period to find evidence of enhanced offshoring-related activities in these countries. The focus is on NMS-10, i.e. NMS-12 excluding Cyprus and Malta. Given the shortcomings of available statistical data and instruments for gauging the scale and impact of services offshoring, the paper adopts a three-tier approach based on BoP trade and FDI statistics, complemented by alternative sources of information. Notwithstanding the caveats associated with this kind of empirical exercise, the paper documents an accelerated pace of offshoring-related activities in the selected NMS, under both forms: international outsourcing and captive offshoring. Its findings show that the fastly growing exports in some individual services categories over recent years, coupled with the ongoing favourable changes in the structure and performance of NMS services trade are largely driven by enhanced offshoring activities hosted by their economies. Further, the paper highlights the NMS capabilities to cope with the challenges raised by the increasingly competitive global offshoring landscape, as measured by competitiveness indicators. Finally, the findings of the paper confirm that current anecdotal information and consulting companies-based projections on NMS growing attractiveness as targets of offshoring decisions by TNC originating both inside and outside EU-15 are widely backed up by available statistical data. The paper is organised in two parts under the same title.
