Architettura e lavoratori del legno: alcune intersezioni e intrecci professionali nella Sicilia d'età moderna
2012
Il contributo individua e analizza intersezioni e intrecci professionali tra lavoratori del legno e architetti nell'architettura siciliana d'età moderna. In questo contesto e alla luce dei documenti rintracciati è possibile ricostruire traiettorie professionali che dal mondo della lavorazione del legno si estendono all'architettura: la presente ricerca ne indica casi significativi.
Tra connoisseurship e militanza culturale: Pietro Selvatico e Ernst Förster nell'oratorio di San Giorgio (1837-1846)
2020
The Nineteenth-Century rediscovery of the Oratory of S. Giorgio offers the opportunity to question the conservation methods, historical analysis and creative reception of fourteenth-century painting in this crucial period for the establishment of art history as a scientific discipline. This essay reconstructs the historical circumstances of the discovery of Altichiero’s frescoes and the consequent discussions among connoisseurs concerning the autography and the cultural value of these paintings. The protagonists of this scholarly discussion – the German art historian Ernst Förster (1800-1885) and his Italian colleague Pietro Selvatico Estense (1803- 1880) – see the Paduan fresco cycle as a …
The role of contact chemoreception in the host location process of an egg parasitoid
2016
Taste allows insects to detect palatable or toxic foods, identify a mate, and select appropriate oviposition sites. The gustatory system strongly contributes to the survival and reproductive success of many species, yet it is rarely studied in insect parasitoids. In order to locate and assess a host in which they will lay their eggs, female wasps actively search for chemical cues using their sensory organs present mainly on the antennae. In this paper, we studied the role of antennal taste sensilla chaetica in the perception of contact semiochemicals in Trissolcus brochymenae (Hymenoptera: Platygastridae), an egg parasitoid of the brassicaceae pest Murgantia histrionica (Heteroptera: Pentat…
A Simple Cardiovascular Model for the Study of Hemorrhagic Shock
2020
Hemorrhagic shock is the number one cause of death on the battlefield and in civilian trauma as well. Mathematical modeling has been applied in this context for decades; however, the formulation of a satisfactory model that is both practical and effective has yet to be achieved. This paper introduces an upgraded version of the 2007 Zenker model for hemorrhagic shock termed the ZenCur model that allows for a better description of the time course of relevant observations. Our study provides a simple but realistic mathematical description of cardiovascular dynamics that may be useful in the assessment and prognosis of hemorrhagic shock. This model is capable of replicating the changes in mean …
Focused Ultrasound Effects on Osteosarcoma Cell Lines
2019
MRI guided Focused Ultrasound (MRgFUS) has shown to be effective therapeutic modality for non-invasive clinical interventions in ablating of uterine fibroids, in bone metastasis palliative treatments, and in breast, liver, and prostate cancer ablation. MRgFUS combines high intensity focused ultrasound (HIFU) with MRI images for treatment planning and real time thermometry monitoring, thus enabling non-invasive ablation of tumor tissue. Although in the literature there are several studies on the Ultrasound (US) effects on cell in culture, there is no systematic evidence of the biological effect of Magnetic Resonance guided Focused Ultrasound Surgery (MRgFUS) treatment on osteosarcoma cells, …
The Sound of Emotion
2014
What is the effect of performers’ experienced emotions on the auditory characteristics of their performances? By asking performers to play a music phrase in response to three different instructions we attempted to answer this question. Performers were instructed to do the following: 1) play while focusing on the technical aspects of their playing; 2) give an expressive performance; and 3) focus on their experienced emotions, prior to which they were subjected to a sadness-inducing mood induction task. Performers were interviewed after each playing condition. We analyzed the tempo, articulation, dynamics, timbre, and vibrato of the performances obtained as well as the interview data. A focus…
Early prediction of COVID-19 outcome using artificial intelligence techniques and only five laboratory indices
2022
We aimed to develop a prediction model for intensive care unit (ICU) hospitalization of Coronavirus disease-19 (COVID-19) patients using artificial neural networks (ANN). We assessed 25 laboratory parameters at first from 248 consecutive adult COVID-19 patients for database creation, training, and development of ANN models. We developed a new alpha-index to assess association of each parameter with outcome. We used 166 records for training of computational simulations (training), 41 for documentation of computational simulations (validation), and 41 for reliability check of computational simulations (testing). The first five laboratory indices ranked by importance were Neutrophil-to-lymphoc…
Crowdsourced analysis of fungal growth and branching on microfluidic platforms
2021
Fungal hyphal growth and branching are essential traits that allow fungi to spread and proliferate in many environments. This sustained growth is essential for a myriad of applications in health, agriculture, and industry. However, comparisons between different fungi are difficult in the absence of standardized metrics. Here, we used a microfluidic device featuring four different maze patterns to compare the growth velocity and branching frequency of fourteen filamentous fungi. These measurements result from the collective work of several labs in the form of a competition named the “Fungus Olympics.” The competing fungi included five ascomycete species (ten strains total), two basidiomycete…
A Laboratory Dust Generator Applying Vibration to Soil Sample: Mineralogical Study and Compositional Analyses
2020
International audience; A laboratory study was carried out using a vibrating system (SyGAVib) to produce aerosols from four soils collected in the central Tunisian region around Sfax. The aim of this device is to mimic dust emission by natural wind erosion. Using compositional analysis, the dust produced was compared to (i) dust generated in a wind tunnel by the same soils, (ii) fine sieved and (iii) original bulk soils, and (iv) naturally occurring aerosol samples collected in the same area. The relative quartz content strongly decreases from bulk to fine soils, and again from fine soils to both wind tunnel and vibration‐generated aerosols. Compositional data analysis (CoDA) clearly shows …
Disclosing Conflict of Interest - Do Experience and Reputation Matter?
2009
In a controlled laboratory experiment, we investigate the effects of disclosing conflicts of interest on the reporting of information providers. First, we replicate the findings of Cain, Loewenstein, and Moore (2005) that such disclosure makes misreporting more likely as it removes moral concerns. Second, we observe that these effects diminish given experience and find, to the opposite, that disclosure reduces bias in auditors' reporting as predicted by economic theory. Third, we identify disclosure of conflicts of interest as a potential impediment to reputation formation.
