The Transmission of Birgittine and Catherinian Works within the Mystical Tradition: Exchanges, Cross-Readings, Connections
No full textThis chapter aims to trace the role of Catherine of Siena and Birgitta of Sweden within the Observant reform. After having described the particular modes of the transmission of their mystical works, i.e. respectively the Dialogo and the Revelations, the author focuses on some significant manuscripts from the Italian peninsula and on a few key-figures, both men and women—Alfonso Pecha of Jaén, Cristoforo di Gano Guidini, Tommaso da Siena, Chiara Gambacorta, the Birgittine nuns of Paradiso in Florence and Syon in England and others— in order to demonstrate that there were a fluid context of exchanges between Birgittine and Catherinian circles
C.A.L.M.A. Compendium Auctorum Latinorum Medii Aevi : 7.3 (2022), Ida de Montibus comitissa - Iodocus Gaverius
No full textL’opera è un repertorio riguardante gli autori medievali le cui opere sono databili entro un arco cronologico compreso tra il VI secolo e la prima metà del XVI. Per ciascun autore, il Compendium fornisce: 1 - una scheda contenente la bibliografia generale sull’autore e che comprende: i repertori specializzati, i lessici di riferimento nazionali e internazionali, i dizionari enciclopedici, i manuali generali e alcuni studi sul singolo autore; 2 - l’elenco delle opere attribuite all’autore, incluse quelle di dubbia autenticità, e per ciascuna delle quali si segnala: il repertorio o i repertori di riferimento, l’edizione o le edizioni, i manoscritti relatori, gli studi specifici.
La pubblicazione è in fascicoli semestrali, ordinati per serie alfabetica degli autori.Founded by Michael Lapidge and the late Claudio Leonardi, and now edited by Michael Lapidge, Silvia Nocentini, and Francesco Santi, C.A.L.M.A. is designed to serve as a complete bibliography of medieval and humanist authors. Although various bibliographical reference-works exist for specialized disciplines (e.g. medicine) or for various religious orders (e.g. Franciscans), C.A.L.M.A. is the only reference-work which attempts coverage of all Latin authors in all disciplines and all religious orders.
For each author C.A.L.M.A. provides the following information:
First, a general bibliography (BIBL.GEN.) listing biographical and cultural studies on the author and his/her milieu, in the order of their date of publication. Under this heading are included references to entries in the relevant medieval encyclopedias (e.g. Lexikon des Mittelalters) and literary histories (e.g. Manitius), plus all relevant articles and monographs on the author;
Then follows a list of the author’s individual works (including works of doubtful authenticity), in alphabetical order. Published scholarship pertaining to each work is listed under the following headings:
REF: references to the work in alpha-numerical repertories (e.g. Bibliotheca Hagiographica Latina);
MSS: a list of the principal manuscripts which transmit the work—but these are listed only in cases where the work is unpublished, or in cases where a work is transmitted in an autograph manuscript;
ED: a list of published editions of the work (frequently including incunables);
STU: a list of the published studies—philological, historical, etc.—on the individual work.
C.A.L.M.A. is the result of cooperation between a number of European and North American scholars based in various universities: Barcelona, Cambridge, Cassino, Columbus (OH), Florence, Freiburg i.Br., Genoa, Geneva, Milan, Paris, Perugia, Pisa, Rome, Sassari, and Valladolid. Entries compiled by these various scholars are overseen and edited to a standard format by editors in the two principal centres of redaction, Cambridge and Florence. Each volume of C.A.L.M.A. consists of six fascicules; fascicules are issued at regular six-monthly intervals
Biodegradation of PAHs in aggregates of a low permeability soil
No full textIn the bioremediation of low-permeability soils, pollutant and, especially, the oxygen bioavailability are often the rate limiting steps. In cases when a biopile treatment can represent an applicable technique, pretreatment of the excavated soil is often necessary to attain an adequate air-filled porosity in the soil and to avoid the presence of large soil aggregates. The present work was performed to evaluate the influence of soil aggregate size in the bioremediation of a silt-clay type soil contaminated by PAHs. Microcosms were arranged with spherical soil aggregates of different diameter in near water-saturation conditions. Concentration of two and three aromatic ring PAHs, total biomass, and respiration rates were monitored. PAH concentration profiles inside the particles were also obtained. A simple and quick way to estimate the critical dimension of the soil aggregates was developed based on the evaluation of an oxygen penetration depth, that is, the distance from the external surface to the aggregate core beyond which oxygen concentration is practically zero. A very different time course of PAHs consumption was found in the external layer and the inner core of the aggregates as well as in aggregates of different dimensions. The results suggest that only the 3 mm external layer of the sphere is not limited by oxygen diffusion
An alternative screening model for the estimation of outdoor air concentration at large contaminated sites
No full textSimplified analytical solutions of fate and transport models are often used to carry out risk assessment on contaminated sites, to evaluate the long-term air quality in relation to volatile organic compounds in either soil or groundwater. Among the different assumptions employed to develop these solutions, in this work we focus on those used in the ASTM-RBCA â\u80\u9cbox modelâ\u80\u9d for the evaluation of contaminant dispersion in the atmosphere. In this simple model, it is assumed that the contaminant volatilized from the subsurface is dispersed in the atmosphere within a mixing height equal to two meters, i.e. the height of the breathing zone. In certain cases, this simplification could lead to an overestimation of the outdoor air concentration at the point of exposure. In this paper we first discuss the maximum source lengths (in the wind direction) for which the application of the â\u80\u9cbox modelâ\u80\u9d can be considered acceptable. Specifically, by comparing the results of â\u80\u9cbox modelâ\u80\u9d with the SCREEN3 model of U.S.EPA we found that under very stable atmospheric conditions (class F) the ASTM-RBCA approach provides acceptable results for source lengths up to 200 m while for very unstable atmospheric conditions (class A and B) the overestimation of the concentrations at the point of the exposure can be already observed for source lengths of only 10 m. In the latter case, the overestimation of the â\u80\u9cbox modelâ\u80\u9d can be of more than one order of magnitude for source lengths above 500 m. To overcome this limitation, in this paper we introduce a simple analytical solution that can be used for the calculation of the concentration at the point of exposure for large contaminated sites. The method consists in the introduction of an equivalent mixing zone height that allows to account for the dispersion of the contaminants along the source length while keeping the simplistic â\u80\u9cbox modelâ\u80\u9d approach that is implemented in most of risk assessment tools that are based on the ASTM-RBCA standard (e.g. RBCA toolkit). Based on our testing, we found that the developed model replicates very well the results of the more sophisticated dispersion SCREEN3 model with deviations always below 10%. The key advantage of this approach is that it can be very easily incorporated in the current risk assessment screening tools that are based on the ASTM standards while ensuring a more accurate evaluation of the concentration at the point of exposure
