Il centro storico di Modica : lo spazio pubblico dei servizi
2016
Il dibattito sulla dotazione di attrezzature pubbliche a servizio della residenza si è concentrato per lungo tempo sulla qualità o le caratteristiche prestazionali in contrapposizione alla previsione puramente quantitativa, rimarcando implicitamente come obsoleto il DM 1444/68. In particolare, la possibilità prevista dalla normativa di computare al doppio le aree dedicate alle attrezzature nei centri storici, unitamente all’uso diffuso d’includere i servizi erogati dai privati hanno, difatti, scoraggiato nel tempo la ricerca teorica e talvolta anche la sperimentazione pratica nel campo dell’incremento quanti-qualitativo. Se da una parte la mancanza di adeguate dotazioni territoriali nel mer…
El centro, coartada de la confusión

Treatment with the anti-tumor drugs, cis-platin and mafosfamide, does not affect the structure of prekinetochores in a human breast cancer cell line.…
1996
Abstract The goal of the present article was to determine whether a nuclear parameter, centromere structure of interphase cells, could serve as an indicator to assess cellular damage caused by anti-tumor drugs. These were cis-platin and mafosfamide, which are widely used for the management of solid tumors. To visualize the centromeres, we probed treated and untreated cells of a human breast cancer cell line, MX-1, with a human anti-centromere serum. The serum was obtained from a scleroderma patient and detects antigens associated with prekinetochores of the decondensed chromosomes. The DNA was simultaneously displayed by a specific fluorescent dye. The cells were grown on coverslips, incuba…
Bond strength evaluation of the veneering-core ceramics bonds.
2009
The purpose of this study was to determine whether the bond of veneering porcelain to a ceramic core in bilayered ceramics was similar to that of the metal ceramic control of well known behaviour. Six groups of nine specimens each were fabricated, whose dimensions were 15 mm long and 8 mm in diameter at the core, and 2 mm long and 8 mm in diameter for the veneer. The groups were GR. 1 (control group): CrNi alloy/d.SIGN (Ivoclar), GR. 2: IPS e.maxPress/IPS e.maxCeram (Ivoclar), GR. 3: IPS e.maxZirCad/ IPS e.maxZirPress (Ivoclar), GR. 4: IPS e.maxZirCad/IPS e.maxCeram (Ivoclar), GR. 5: Lava Frame (3M ESPE)/ Lava Ceram (3M ESPE) and GR. 6: Lava Frame (3M ESPE)/IPS e.maxCeram (Ivoclar). A shear…
Sulle tracce di un’antica prassi: la c.d. cessione della moglie
2011
This essay analyzes the evidence which allows us to glimpse the traces of an archaic practice of wife ceding and its development to the late Republican age. The sources which recount the episode of the ceding of Marcia and Livia Drusilla and a passage of the so-called Laudatio Turiae, with special reference to lines 35-36 and the proposed integration of Mommsen liberi [communes] are analyzed. In relation to such integration the Author analyzes Aug. De Bono Coniugali 15. 17 which she ascribes to the ancient biblical practices, criticizing the attribution of the expression “liberi communes” to the Roman law. Finally the Author suggests a hypothesis on the value of the expression koinonìa paid…
Cessione del credito e modificazione del lato attivo dell'obbligazione
2012
Il saggio affronta l'istituto della cessione del credito e si interroga sulla reale portata dogmatica. In particolare, l'autore si sofferma sugli effetti che la cessione del credito determina sul rapporto obbligatorio. La modificazione di quest'ultimo che la cessione produce sta alla base della regola di cui all'art. 1264 c.c., che, a dispetto di quanto ritenuto dalla dottrina largamente prevalente, non contiene una disposizione sull'efficacia relativa della cessione, ma disciplina la fase conclusiva del procedimento di modificazione del lato attivo dell'obbligazione. L'autore critica infine la tesi secondo cui la cessione del credito può determinare una novazione soggettiva attiva, la qual…

CtsR is the master regulator of stress response gene expression in Oenococcus oeni.
2005
ABSTRACT Although many stress response genes have been characterized in Oenococcus oeni , little is known about the regulation of stress response in this malolactic bacterium. The expression of eubacterial stress genes is controlled both positively and negatively at the transcriptional level. Overall, negative regulation of heat shock genes appears to be more widespread among gram-positive bacteria. We recently identified an ortholog of the ctsR gene in O. oeni . In Bacillus subtilis , CtsR negatively regulates expression of the clp genes, which belong to the class III family of heat shock genes. The ctsR gene of O. oeni is cotranscribed with the downstream clpC gene. Sequence analysis of t…
Capitolo VIII della Carta dell’ONU e modelli di azione militare regionale
2019
This contribution deals with relations between regional organizations and the UN Security Council under Chapter VIII of the UN Charter. In this respect, the most recent trends are a shift from subsidiarity to a more equal partnership between these two subjects. The two models of action by delegation or authorization of the Security Council are in fact autonomous. This is demonstrated by the preparatory works of the UN Charter and subsequent practice. The model of authorized regional action enriches the range of instruments that the United Nations Charter provides for the maintenance of peace and collective security.
Nanoscale ear drum: graphene based nanoscale sensors.
2012
The difficulty in determining the mass of a sample increases as its size diminishes. At the nanoscale, there are no direct methods for resolving the mass of single molecules or nanoparticles and so more sophisticated approaches based on electromechanical phenomena are required. More importantly, one demands that such nanoelectromechanical techniques could provide not only information about the mass of the target molecules but also about their geometrical properties. In this sense, we report a theoretical study that illustrates in detail how graphene membranes can operate as nanoelectromechanical mass-sensor devices. Wide graphene sheets were exposed to different types and amounts of molecul…
