Design and Synthesis of Novel Sirtuin Inhibitors as Useful Tools in Understanding Their Potential Activity Against Cancer
No full textMotivi letterari nei libri per l’infanzia di Paolo Di Paolo
No full textThe article, organised in the form of a discussion, aims to analyse the themes and motifs of Paolo Di Paolo’s works that are addressed to young audiences. The author has recently published a large number of volumes directed just at younger readers. When beholding the titles that constitute the author’s bibliography, the reader is struck by Di Paolo’s predisposition to transform literary classics: as much in Giacomo il signor bambino as in the edition of the Divina Commedia, the author’s goal is to try to reach his new readers. Therefore, Di Paolo proves to be a prolific author of the genre; in fact, in his bibliography, volumes of fairy tales with a classic slant, such as La mucca volante, are listed as well.L’articolo contiene un’analisi di temi e di motivi delle opere di Paolo Di Paolo dirette al pubblico più piccolo. L’autore negli ultimi anni ha pubblicato un cospicuo numero di volumi indirizzati, infatti, proprio ai lettori più giovani. Ciò che stupisce scorgendo i titoli che costituiscono la bibliografia dell’autore, è la predisposizione a trasformare i classici della letteratura: tanto in Giacomo il signor bambino quanto nell’edizione della Divina Commedia l’obiettivo è cercare di raggiungere i lettori più giovani. Di Paolo si dimostra, quindi, un autore prolifico del genere, tant’è che nell’elenco non mancano volumi fiabeschi dal taglio classico come La mucca volante. Analizzare le opere giovanili dello scrittore costituisce un fatto inedito

Lavoisierite, Mn2+8[Al10(Mn3+Mg)][Si11P]O44(OH)12, a new mineral from Piedmont, Italy: the link between “ardennite” and sursassite
No full textThe new mineral species lavoisierite, ideally Mn2+8[Al10(Mn3+Mg)][Si11P]O44(OH)12, has been discovered in piemontite-bearing micaschists belonging to the Piedmontese Nappe from Punta Gensane, Viù Valley, Western Alps, Italy. It occurs as yellow-orange acicular to prismatic-tabular crystals up to a few millimeters in length, with white streak and vitreous luster, elongated along [010] and flattened on {001}. Lavoisierite is associated with quartz, ‘‘mica,’’ sursassite, piemontite, spessartine, braunite, and ‘‘tourmaline.’’ Calculated density is 3.576 g cm-3. In plane-polarized light, it is transparent, pleochroic, with pale yellow parallel to [010] and yellow-orange normal to this direction; extinction is parallel and elongation is positive. Birefringence is moderate; the calculated average refraction index n is 1.750. Lavoisierite is orthorhombic, space Group Pnmm, with a 8.6891(10), b 5.7755(3), c 36.9504(20) Å,
V 1854.3(2) Å3, Z = 2. Calculated main diffraction lines of the X-ray powder diffraction pattern are [d in Å , (I), (hkl); relative intensities are visually estimated]: 4.62 (m) (112), 2.931 (vs) (1.1.10), 2.765 (s) (1.1.11), 2.598 (s) (310), 2.448 (ms) (028). Chemical analyses by electron microprobe give (in wt%) P2O5 2.08, V2O5 0.37, SiO2 34.81, TiO2 0.13, Al2O3 22.92, Cr2O3 0.32, Fe2O3 0.86, Mn2O3 6.92, MnO 19.09, MgO 5.73, CaO 1.94, Na2O 0.01, H2O 5.44, sum 100.62 wt%. H2O content was calculated from structure refinement. The empirical formula, based on 56 anions, is (Mn2+5.340 Mg1.810Ca0.686Na0.006)S=7.852 (Al8.921Mn3+1.739Mg1.010Fe3+0.214Cr0.084Ti0.032)S=12.000 (Si11.496P0.582V0.081)S=12.159O43.995(OH)12.005. The crystal structure of lavoisierite was solved by direct methods and refined on the basis of 1743 observed reflections to R1 = 4.6 %. The structure is characterized by columns of edge-sharing octahedra running along [010] and linked to each other by means of [SiO4], [Si2O7], and [Si3O10] groups. Lavoisierite, named after the French chemist and biologist Antoine-Laurent de Lavoisier (1743–1794), displays an unprecedented kind of structure, related to those of ‘‘ardennite’’ and sursassite
Pier Paolo Pasolini e la società: il "sogno di una cosa" travolto dalla "nuova preistoria"
No full textL’articolo prende in esame – nel centenario della nascita – il “pensiero politico” di Pier Paolo Pasolini. Vengono pertanto scandagliati (soprattutto) i suoi scritti sulla società, ma frequenti sono le incursioni nella letteratura e soprattutto nel cinema di questo autore del tutto originale. Ne emerge lo spessore di concetti spesso usati dal poeta per analizzare e criticare il presente: Nuova Preistoria, nuovo capitalismo, consumismo, edonismo, il Potere, il Palazzo, il Processo, sviluppo e progresso, sacralità in primis. Si evidenzia inoltre come l’occhio e il giudizio di Pasolini siano stati principalmente guidati dalla passione e solo di rimando dalla ragione. Un ruolo non secondario nella sua percezione del reale ha inoltre assunto la sua omosessualità. Nella parte finale dello scritto si analizzano alcuni strumenti tecnici utilizzati dall’autore per svolgere la propria opera di comprensione del presente e della sua conseguente traduzione artistico-critica.The article examines - in the centenary of his birth - the "political thought" of Pier Paolo Pasolini.
Therefore, it scrutinizes (above all) his writings on society, but there are frequent incursions into the literature and especially into the cinema of this completely original author. What emerges is the depth of concepts often used by the poet to analyze and criticize the present: New Prehistory, new capitalism, consumerism, hedonism, Power, the Palace, the Process, development and progress, sacredness in primis. It also shows how Pasolini's eye and judgment were mainly guided by passion and only by reason. His homosexuality also played a significant role in his perception of reality. In the final part of the paper we analyze some technical tools used by the author to carry out his work of understanding the present and its consequent artistic-critical translation
