Sampling problems in the radiocarbon dating of old mortars and plasters with the “pure lime lumps” technique
No full textSeveral scientific papers describe the radiocarbon dating of lime mortars and plasters [Folk and Valastro, 1976; Van Strydonck et al., 1992; Hale et al., 2003; Nawrocka et al., 2005]. In many cases, these lime based mixtures are dated by using pieces of organic materials contained within the mix such as charcoal, wood or straw. However, this type of application can only provide post-quem chronological information. The results obtainable, in fact, are not connected with the hardening process of lime but with the formation process of the organic material embedded in the mixture and this can be a quite important limitation, in the archaeological interpretation of the results obtained by radiocarbon dating.
Rarer and with not yet fully reproducible results are the papers dealing with the radiocarbon dating of calcium carbonate contained in the mortars as binder phase. In this case, the 14 C dating is carried out directly on the calcium carbonate precipitated during the hardening process of lime by the reaction between calcium hydroxide and atmospheric carbon dioxide. As the content of 14 C contained in the newly formed calcium carbonate reflects the 14 C concentration in the atmosphere at the time of hardening, this material can be used for the radiocarbon dating of old mortars and plasters.
Although the method is quite simple in its basis principle, relevant issues come from the contamination problems of the dated samples with other carbon sources. Grains of carbonate sand or underburned pieces of the same limestone used to produce the lime, that are originally mixed with the binder cannot be, in fact, completely removed from the mixtures. These materials do not contain radioactive carbon 1 but behave as the carbonated lime during the analyses. For this reason, the radiocarbon dating of old lime-based mixtures has not yet been used intensively over the past decades.
Over the past years, this problem led to the development of new techniques for the sample preparation (e.g. Sonninen and Junger, 2001) and among these techniques, the so called “pure lime lumps” represents a fast and reliable method. The technique is based on the use of lumps of pure lime, very often embedded in old lime based mixtures as material for the radiocarbon dating.
Because these lumps are made of pure lime [Bugini and Toniolo, 1990] any contamination problem is avoided [Pesce and Ball, 2012]. However, despite the remarkable results already achieved with this technique [Pesce et al., 2009; Pesce et al., 2012; Pesce et al., 2013], the sample collection is still a very important issue for a successful application of the radiocarbon dating.
This paper describes the main sampling problems faced during a research on the accuracy and precision of the “pure lime lumps” technique, founded by the University of Genoa 2 and carried out together by the University of Genoa and the and CEDAD in Italy and the University of Bath in the United Kingdom. Results of this research were presented at the 21 st International Radiocarbon Conference, held in Paris from 9th to 13th July 2012

No full textL'attrice Caterina Murino si racconta agli studenti e alle studentesse, in una chiacchierata che verterà sugli aspetti gratificanti e su quelli più problematici del suo mestiere, sulla gestione della carriera, sulla formazione, sui casting. Al termine dell'incontro, si terrà il lancio ufficiale del sito del progetto di ricerca F-Actor, una piattaforma dove saranno resi via via disponibili materiali, esiti della ricerca e altre risorse utili a un pubblico di esperti e appassionati.
L'incontro è parte del ciclo "Attrici e attori incontrano il pubblico", ed è organizzato dai ricercatori del progetto PRIN 2017 "F-Actor. Forme dell’attorialità mediale contemporanea. Formazione, professionalizzazione, discorsi sociali in Italia (2000-2020)", in collaborazione con La Soffitta. F-Actor è finanziato dal Ministero dell'Università e della Ricerca e indaga nuove forme di performance, percorsi di carriera di attrici e attori cinematografici e televisivi, e gli intermediari chiave che ne influenzano gli sviluppi professionali. Il progetto è coordinato dal prof. Francesco Pitassio dell’Università di Udine, e le altre tre unità di ricerca sono basate a Bologna, Roma Sapienza e Torino. L’evento vedrà il coinvolgimento di studenti e studentesse di corsi di laurea magistrale e triennale degli atenei coinvolti

The nucleus under the microscope. A biophysical approach.
No full textAt the beginning of 1950, many researchers challenged the possibility to overcome the fundamental Abbe limit. An attempt was made by Giuliano Toraldo di Francia, who showed that the width of the point-spread function can be reduced applying a filtering technique (called apodozation) (1). In 1994, a revolutionary event took place in the field of optical microscopy: Hell described a method for circumventing the light diffraction barrier (2). In this way, details that were not visible in diffraction-limited techniques could be imaged using a fluorescence microscopy. Nowadays, these methods termed Far-field fluorescence microscopy or nanoscopy techniques, has become an indispensable tool for scientist to address important biological and biophysical questions at the single molecule level. To highlight the outstanding importance of such techniques, the Royal Swedish Academy of Sciences awarded Eric Betzig, Stefan W. Hell, and William E. Moerner the Nobel Prize in Chemistry 2014 “for the development of super-resolved fluorescence microscopy”. In addition, several important technical improvements, including confocal laser scanning microscopy (CLSM) (3), multiphoton microscopy, 4Pi (4) and I5M (5) have had an important role in the field of optical microscopy.
On the other side, in 2015 Boyden and colleagues developed a new method termed Expansion Microscopy (ExM), which allows expanding uniformly biological samples by increasing the relative distances among fluorescent molecules labelling specific cellular components (6). ExM permits to achieve a lateral resolution of about 65 nm, using a conventional - diffracted microscope. However, all super resolution methods demand a particular attention in the sample preparation. Achieving super resolved images require the optimization of every steps involved in the labelling process, from the expression of a fluorescent proteins to the fixation of the biological samples. In the last years, these labelling strategies have obtained a critical role in the field of fluorescence microscopy. In particular, the design and the localization precision of specific affinity probes are crucial features that can restrict the applicability of these techniques. In this work, several labelling approaches and optimization of different staining protocol for super resolution techniques were addressed. My effort was focused on STED nanoscopy and ExM, and how to optimize the labelling protocol, the fluorophores choice for a high labelling density. The optimization of the steps involved in the labelling processes allows me combining ExM with STED nanoscopy (ExSTED), to enhance the final resolution (7). In addition, these techniques were used to decipher molecular assemblies in the cellular nuclei. In particular, my attention was focused on an important layer termed nuclear envelope (NE) (8).
This nuclear region encases the genetic material, maintains the regular shape of the nucleus
and regulates the gene expression. NE is composed by two lipid bilayer and different class of
proteins, which pass through or are strictly linked to the nuclear membranes. Nuclear pore
complexes (NPCs) and nuclear lamins, two classes of proteins belonging to the NE, were
investigated in this work. In particular, NPCs was used to evaluate the isotropy and calculate
the expansion factor (EF) at the nanoscale level in ExM. In this work, we show that Nup153, a
filamentous subunit localized in the nuclear pore basket (9), is a good reporter to verify the
isotropy of the expansion process and its quantification. In addition, nuclear lamins, in
particular lamin A (LA) and its mutation ΔLA50 (10), were used to investigate the physiological
and pathological nuclear membrane invagination in normal and aging cells
I discorsi di Paolo in Atti 13 e 14: mise en histoire e memoria social
No full textL’ipotesi che vogliamo presentare è che Luca scrive scegliendo eventi che sono importanti per i suoi destinatari. Se un testo è sempre scritto in funzione dei lettori supposti, si può dire che nella sua redazione Luca ha selezionato eventi, occasioni, ambienti, personaggi, concezioni, scenari che erano ben noti ai suoi destinatari, cioè che sono per essi “parlanti”. In questo modo essi potevano recepire il racconto come parte della propria ‘memoria sociale’. È per il tramite di questi concreti agganci che Luca riesce a penetrare nella ‘memoria sociale’ dei suoi destinatari per modificarla con le nuove concezioni e informazioni che vuole trasmettere
