Gemelle diverse. Las iglesias de la Santísima Trinidad de Delia y de San Nicolò Regale en Trápani, Sicilia
2019
[EN] The work develops the necessary phases before arriving at a restoration project. The main objectives are: the study and historical-architectural analysis, the knowledge of the current management and enhancement of the two churches, the proposal of strategies to show the value of the remains of the past and to educate the new generations and the development of a method. In addition to the data collection “in situ” relative to the current conditions of the elements, their state of conservation and the documentation of existing pathologies, an architectural survey has been carried out to perform the comparative analysis of both churches and the proposals of action. The two architectures a…
Alpha-1 antitrypsin deficiency: outstanding questions and future directions
2018
BACKGROUND: Alpha-1 antitrypsin deficiency (AATD) is a rare hereditary condition that leads to decreased circulating alpha-1 antitrypsin (AAT) levels, significantly increasing the risk of serious lung and/or liver disease in children and adults, in which some aspects remain unresolved. METHODS: In this review, we summarise and update current knowledge on alpha-1 antitrypsin deficiency in order to identify and discuss areas of controversy and formulate questions that need further research. RESULTS: 1) AATD is a highly underdiagnosed condition. Over 120,000 European individuals are estimated to have severe AATD and more than 90% of them are underdiagnosed. CONCLUSIONS: 2) Several clinical and…
Treatment of Anderson-Fabry Disease
2020
Fabry disease is an X-linked disorder of glycosphingolipid metabolism that results in progressive accumulation of neutral glycosphingolipids, predominantly globotriaosylsphingosine (Gb3) in lysosomes, as well as other cellular compartments of several tissues, causing multi-organ manifestations (acroparesthesias, hypohidrosis, angiokeratomas, signs and symptoms of cardiac, renal, cerebrovascular involvement). Pathogenic mutations lead to a deficiency of the lysosomal enzyme alpha-galactosidase A (GLA). In the presence of high clinical suspicion, a careful physical examination and specific laboratory tests are required. Finally, the diagnosis of Fabry’s disease is confirmed by the demonstrat…
Image Content Enhancement Through Salient Regions Segmentation for People With Color Vision Deficiencies
2019
Color vision deficiencies affect visual perception of colors and, more generally, color images. Several sciences such as genetics, biology, medicine, and computer vision are involved in studying and analyzing vision deficiencies. As we know from visual saliency findings, human visual system tends to fix some specific points and regions of the image in the first seconds of observation summing up the most important and meaningful parts of the scene. In this article, we provide some studies about human visual system behavior differences between normal and color vision-deficient visual systems. We eye-tracked the human fixations in first 3 seconds of observation of color images to build real f…
Vucciria a Palermo: narrazioni contemporanee da Guttuso alla Street Art
2020
Piazza Caracciolo nella Vucciria a Palermo era una dei più antichi e un tempo floridi mercati della città. Purtroppo lo spopolamento prima e l’abbandono del mercato dopo ha determinato la decadenza dello stesso e della sua consistenza storica architettonica. La Vucciria, in età contemporanea, è stata ispiratrice di artisti, scrittori e registi, che come Guttuso, Sciascia, Taravella e Camilleri, che l’hanno immortalata nelle loro opere. Un rinnovato interesse alla conservazione e valorizzazione dell’area oggi è pure espresso dalla Street Art, che si aggiunge e indica una nuova vita per la città storica. Piazza Caracciolo in the Vucciria in Palermo was one of the oldest and once flourishing m…
Pienamente conservare per pienamente fruire: il paradigma della Vucciria di Palermo nel Progetto I-Access
2021
Già dal nome la città di Palermo rivela una delle sue peculiarità più significative, ovvero la capacità di accogliere: dal greco «Pan ormos» - tutto porto. In generale, consapevole della vocazione di Palermo, il mercato della Vucciria è stato scelto per illustrare i contenuti del Progetto Interreg Italia-Malta, I-Access di Implementare l'accessibilità alla fruizione e alla conoscenza del centro storico urbano e per le somiglianze e le differenze riscontrate nel La Valletta e Palermo. Il progetto I-ACCESS ha verificato un metodo per promuovere l'accessibilità in senso culturale e fisico e questa esperienza può essere ripetuta in altri centri storici. La conoscenza della realtà materiale del …
Membrane distillation heat transfer enhancement by CFD analysis of internal module geometry
2011
Module geometry optimisation can be a crucial matter in all separation processes using selective or hydrophobic membranes, e.g. reverse osmosis (RO) and membrane distillation (MD). In fact the choice of suitable channel shape and size can dramatically affect the performance of the process. With reference to the membrane distillation process, temperature polarization phenomena and pres¬sure drops along the channels largely affect the process efficiency (i.e. the efficient use of temperature driving force for the passage of vapour through the membrane) as well as pressure distribution, module mechanical resistance and pumping costs. Several works have been presented so far in literature on th…
L’allevamento bovino nella valle del Torto: un caso di zootecnia sostenibile in Sicilia
2011
In spite of not being the main activities of Sicilian agriculture, zootechny plays a very important social role, even more than economic, for a large part of Sicily. The crisis that has hit the industry since early 2000s, and particularly cattle livestock, caused the closure of many holdings and a strong decrease in the number of animals bred, both meat and dairy cattle. The beef cattle population in the Valle del Torto, in the province of Palermo (area covered by this study), for many decades has significantly contributed to the development of a rural community that trough this activity created his own wealth, income and economic stability. The crisis that over the last decade has affected…
Using Polynomial Loss and Uncertainty Information for Robust Left Atrial and Scar Quantification and Segmentation
2022
Automatic and accurate segmentation of the left atrial (LA) cavity and scar can be helpful for the diagnosis and prognosis of patients with atrial fibrillation. However, automating the segmentation can be difficult due to the poor image quality, variable LA shapes, and small discrete regions of LA scars. In this paper, we proposed a fully-automatic method to segment LA cavity and scar from Late Gadolinium Enhancement (LGE) MRIs. For the loss functions, we propose two different losses for each task. To enhance the segmentation of LA cavity from the multicenter dataset, we present a hybrid loss that leverages Dice loss with a polynomial version of cross-entropy loss (PolyCE). We also utilize …
Inverse Tone Mapping Based upon Retina Response
2014
International audience; The development of high dynamic range (HDR) display arouses the research of inverse tone mapping methods, which expand dynamic range of the low dynamic range (LDR) image to match that of HDR monitor. This paper proposed a novel physiological approach, which could avoid artifacts occurred in most existing algorithms. Inspired by the property of the human visual system (HVS), this dynamic range expansion scheme performs with a low computational complexity and a limited number of parameters and obtains high-quality HDR results. Comparisons with three recent algorithms in the literature also show that the proposed method reveals more important image details and produces …
