"Ragionare dello stato" : studi su Machiavelli
No full textLa complessità del pensiero e l'incisività della scrittura di Machiavelli su aspetti fondamentali del "ragionare dello stato" (le vie ordinarie e straordinarie, le cause delle crisi e i rimedi, i fondamenti e la "ruina" dello stato) sono i temi focali del volume, che raccoglie saggi di: Gennaro Barbuto, Guglielmo Barucci; Anna Maria Cabrini, Marco Geuna, Giovanni Giorgini, Jean-Jacques Marchan
Oral history interview with Sister Mary Cabrini Rohr, Tacoma, Washington
No full textSister Mary Cabrini Rohr (Frances Rohr, 1910-1997) discusses her decade-spanning nursing and teaching career, including her time as director of the School of Nursing at Providence St. Peter Hospital in Olympia, Washington. Special focus is given to the schools 1954 changeover from a three-year professional program to a one-year practical program, a transition that Sister Cabrini personally oversaw.The oral history interviews with Sister Mary Cabrini Rohr form the core of a class project by M. Connie Smith for the Community History Project under the supervision of Professor Michael K. Honey. The contents of Smiths project are contained in a looseleaf binder, which includes the original sound recordings and transcripts of the interviews, Smith's research paper, and related research materials. Also included is a color photograph of the interviewee taken on the day of the second interview; six additional photos showcase items and sites related to St. Peter Hospital and the School of Nursing
Principe e tiranno in Machiavelli
No full textIl saggio prende in considerazione aspetti e nodi problematici relativi alla figura del principe e del tiranno nell’opera machiavelliana: iniziando da un’indagine lessicale e dagli scritti di ufficio di Machiavelli, l’analisi si concentra poi sul "Principe" (in particolare sul cap. VIII, in relazione alla controversa figura dell’Agatocle machiavelliano) e su punti focali dei "Discorsi"
SCRIPPSIELLA-SPINIFERA SP-NOV (PYRRHOPHYTA) - A NEW DINOFLAGELLATE FROM THE NORTHERN ADRIATIC SEA
No full textScrippsiella spinifera sp. nov. (Pyrrhophyta) is described using light and scanning electron microscopy. The species was first found in the Gulf of Trieste (Italy, Northern Adriatic Sea). The cells are 30-52-mu-m long and 21 - 36-mu-m wide. The epitheca is conical and the hypotheca trapezoidal with short spines at its terminal part. The plate tabulation does not differ from other Scrippsiella species. The thecal plates are perforated by numerous pores surrounded by concentric ridges. A taxonomical discussion and a comparison with the other species of the genus are made
Localization of cyanine dye binding to brush-border membranes by quenching of n-(9-anthroyloxy) fatty acid probes
No full textThe location and orientation of 3,3′-dipropylthiodicarbocyanine (diS-C3-(5)) binding sites in renal brush-border membrane vesicles was examined from the quenching of n-(9-anthroyloxy) fatty acid (n-AS) fluorescence. Based on previous kinetic studies (Cabrini, G. and Verkman, A.S. (1986) J. Membrane Biol. 90, 163-175) monomeric aqueous diS-C3-(5) binds to brush-border membrane vesicles (BBMV) by an initial 6 ms association to form bound monomer, a 30-40 ms equilibrium between bound monomer (M) and bound dimer (D), and a 1-1.3 s translocation of D from the outer to inner membrane leaflet. Based on Stern-Volmer and lifetime analyses, M and D quench the fluorescence of the n-AS probes by a collisional mechanism. At low [diS-C3-(5)]/[BBMV] (R), where M predominates, the n-AS quenching efficiencies (Q) are similar (n = 2-16); at high R, where D predominates, Q increases with n (16 > 12 ⋙ 6 > 2), suggesting that M is oriented parallel, and D perpendicular, to the phospholipid chains deep within the membrane. Mixture of diS-C3-(5) with brush-border membrane vesicles containing n-AS in a stopped-flow apparatus gave a biexponential fluorescence decrease (excitation 390 nm, emission above 450 nm) with time constants 30-40 ms and 1-1.5 s; there was no 6 ms quenching process. These findings are incorporated into a model in which diS-C3-(5) adheres loosely to the outer membrane surface in 6 ms, binds parallel to the membrane phospholipid in 30-40 ms, dimerizes and rotates by 90° in much less than 30 ms, and translocates to the opposite half of the bilayer in 1-1.5 s. © 1986
Piume d'angelo, penne di pappagallo
No full textL’intervento intende mettere a fuoco, saggiandone la rete di riprese e rimandi, ora scopertamente ora sottilmente allusivi, uno dei casi più interessanti tra i percorsi intratestuali che il Decameron offre alla suggestione del lettore, nel rapporto che si instaura, a diversa distanza, fra tre novelle di beffa: le novelle di Ferondo e l’abate (III, 8), di frate Alberto (IV, 2) e di frate Cipolla (VI, 10), che hanno come elemento comune la ‘presenza’, in diversi modi contraffatta, dell’arcangelo Gabriele
Machiavelli's Florentine Histories
No full textNel contributo si delinea il contesto in cui si inserisce la scrittura delle Istorie machiavelliane e si mettono a fuoco, sul piano critico e interpretativo, gli snodi fondamentali dell'opera, con particolare riferimento al tema del conflitto e delle divisioni interne nella città di Firenz
