Caterina Colombini, o della cugina sedotta. Una ‘ricostruzione’ della figura di Caterina attraverso i testi
No full textIn this essay the author demonstrates that it is possible to “reconstruct” the figure of Caterina Colombini (1340?-1387) – Giovanni Colombini’s cousin – through a group of texts: the hagiography of Caterina, the letters sent to her by Giovanni Colombini and, finally, Giovanni’s biography written by Feo Belcari. The author divides his text into four parts: the first part analyzes the content of Caterina’s hagiography; the second examines the linguistic form of the hagiographic text; in the third, the author analyzes the latent meaning of the window, a symbolic place where Giovanni and Caterina converse on divine topics; in the last part, to conclude, the teachings that Giovanni gives to Catherine and her spiritual daughters – the Gesuate – are analyzed

Mold contamination in a controlled hospital environment: a 3-year surveillance in southern Italy.
No full textBackground: Environmental monitoring of airborne filamentous fungi is necessary to reduce fungal concentrations
in operating theaters and in controlled environments, and to prevent infections. The present study reports results of
a surveillance of filamentous fungi carried out on samples from air and surfaces in operating theaters and
controlled environments in an Italian university hospital.
Methods: Sampling was performed between January 2010 and December 2012 in 32 operating theaters and five
departments with high-risk patients. Indoor air specimens were sampled using a microbiological air sampler; Rodac
contact plates were used for surface sampling. Fungal isolates were identified at the level of genera and species.
Results: Sixty-one samples (61/465; 13.1%) were positive for molds, with 18 from controlled environments (18/81;
22.2%) and 43 (43/384; 11.2%) from operating theaters. The highest air fungal load (AFL, colony-forming units per
cubic meter [CFU/m3]) was recorded in the ophthalmology operating theater, while the pediatric onco-hematology
ward had the highest AFL among the wards (47 CFU/m3). The most common fungi identified from culture of air
specimens were Aspergillus spp. (91.8%), Penicillium spp., (6%) and Paecilomyces spp. (1.5%). During the study period,
a statistically significant increase in CFU over time was recorded in air-controlled environments (p = 0.043), while
the increase in AFL in operating theaters was not statistically significant (p = 0.145). Molds were found in 29.1% of
samples obtained from surfaces. Aspergillus fumigatus was the most commonly isolated (68.5%).
Conclusions: Our findings will form the basis for action aimed at improving the air and surface quality of these
special wards. The lack of any genetic analysis prevented any correlation of fungal environmental contamination
with onset of fungal infection, an analysis that will be undertaken in a prospective study in patients admitted to
the same hospital
Caterina Tarabotti Unveiled
No full textCaterina Tarabotti (1615–1693) never identified herself as a painter in contemporary
documents or claimed authorship of any picture with her signature. She would have
surely joined the ranks of the many anonymous women painters of her time, were
it not for the art critic and historian Marco Boschini (1602–1681). In his La Carta
del Navegar Pitoresco (1660), Boschini was the first to notice Caterina’s talents and
provide information about her life.1
Alluding to her namesake saint and surname,
Boschini infused the painter’s biography with lyric flair. A light coming out of the
Varotari workshop, Caterina was, according to Boschini, a virgin very gifted in
painting. She herself honored art with her achievements, which came effortlessly.
Comparing her to a silver lamp that never burns out, the author, with a sense of
optimism, concluded that Caterina would live forever and her name would bear
eternal light and splendor

Publisher Copyright: © 2021 by the author. Licensee MDPI, Basel, Switzerland.Organic light emitting transistors (OLETs) represent a relatively new technology platform in the field of optoelectronics. An OLET is a device with a two-fold functionality since it behaves as a thin-film transistor and at the same time can generate light under appropriate bias conditions. This Review focuses mainly on one of the building blocks of such device, namely the gate dielectrics, and how it is possible to engineer it to improve device properties and performances. While many findings on gate dielectrics can be easily applied to organic light emitting transistors, we here concentrate on how this layer can be exploited and engineered as an active tool for light manipulation in this novel class of optoelectronic devices.Peer reviewe

Recovery time and propagation effects of passenger transport disruptions
No full textWe propose a method to evaluate public transport network vulnerability. We study the evolution of the passenger Volume Over Capacity (VOC) ratio throughout the network to measure the spatial and temporal extent of the impacts caused by an unplanned service segment disruption. The VOC ratio provides an indication of the on-board travel comfort, an important level-of-service indicator, as well as reflects the residual capacity for absorbing additional demand. Because of the dynamic nature of public transport systems, disturbances propagate through the network in both time and space. Our modelling approach is able to capture transit system dynamics and quantify the extent to which the network exhibits spillover effects. We apply the method to the case of the rapid public transport system of Stockholm Sweden We demonstrate how the changes in network saturation and the corresponding recovery time can be quantified.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Transport and Plannin

Susceptibility to echinocandins of Candida spp. strains isolated in Italy assessed by European Committee for Antimicrobial Susceptibility Testing and Clinical Laboratory Standards Institute broth microdilution methods
No full textBackground: The echinocandins are recommended as first-line therapy for Candida species infections, but drug resistance, especially among Candida glabrata, is becoming more frequent. We investigated the antifungal susceptibility of anidulafungin, caspofungin, and micafungin against 584 isolates of Candida spp. (bloodstream, other sterile sites) collected from patients admitted to an Italian university hospital between 2000 and 2013. The susceptibility was evaluated using the broth microdilution method according to both the European Committee for Antimicrobial Susceptibility Testing (EUCAST EDef 7.2) and the Clinical Laboratory Standards Institute (CLSI M27-A3). The echinocandin susceptibilities were assessed on the basis of the species-specific clinical breakpoints proposed by the EUCAST version 6.1 and CLSI M27-S4 documents. The two methods were comparable by assessing essential agreement (EA), categorical agreement (CA), and Spearman's correlation analysis (rho, r).
Results: The modal minimum inhibitory concentrations (MICs; mu g . mL(-1)) values by both methods (EUCAST/CLSI) for anidulafungin, caspofungin, and micafungin for each species were, respectively, as follows: C. albicans, 0.03/0.12, 0.016/0.5, and 0.016/0.008; C. parapsilosis complex, 2/1, 2/2, and 2/1; C. tropicalis, 0.06/0.12, 0.06/0.12, and 0.06/0.12; C. glabrata complex, 0.03/0.25, 0.06/0.12, and 0.03/0.06; C. guilliermondii, 2/1, 2/2, and 2/2; and C. krusei, 0.06/0.12, 0.12/0.5, and 0.06/0.12. The overall resistance rates for EUCAST/CLSI were as follows: anidulafungin, 2.5/0.9 %; caspofungin, breakpoint not available/3.8 %; micafungin, 2.7/1.5 %.
Candida glabrata complex was the least susceptible to all three echinocandins, and the percentages of resistant isolates by EUCAST/CLSI were as follows: anidulafungin, 13.5/2.7 %; caspofungin, breakpoint not available/16.2 %; micafungin, 18.9/13.5 %. The overall EA was 93 % for micafungin, 92 % for anidulafungin, and 90 % for caspofungin. The CA was >90 % for all organism-drug combinations with the exception of C. glabrata and anidulafungin (89 %). Spearman's rho for EUCAST/CLSI was 0.89 (p < 0.001) for caspofungin, 0.85 (p < 0.001) for anidulafungin, and 0.83 for micafungin (p < 0.001).
Conclusions: Independent of the procedure applied, no alarming resistance to the tested agents was found, although a reduced susceptibility was detected for C. glabrata complex. The EUCAST and CLSI methods produce similar MICs, indicating that using one method or the other should not result in susceptibilities different enough to affect treatment decisions
