Symmetrical Drug-related Intertriginous and Flexural Exanthema (Baboon Syndrome)
Get PDFBaboon syndrome, also called symmetrical drug-related intertriginous and flexural exanthema (SDRIFE), is an erythematous maculopapular rash that presents in skin folds in a symmetrical pattern. This condition may develop after the patient starts a particular agent. Treatment consists of stopping the associated trigger and medicating with topical or systemic corticosteroids.A 30-year-old man with odynophagia, otalgia and fever was prescribed amoxicillin. He developed erythematous and pruriginous lesions in the cubital fossa and inguinal regions. He attended the emergency department (ED) where he was prescribed penicillin. Lesions continued to progressively worsen with a bilateral symmetrical pattern in the axillary region and later in the nape folds, popliteal regions, and on the perineum and buttocks. The patient presented to the ED for a second time, where he was diagnosed with baboon syndrome and prescribed topical steroids with clear improvement
Modellizzazioni galloromanze: testi didattico-moraleggianti del Due e Trecento
Get PDFThe paper aims to show the deep impact of Gallo-romance literature on shaping
and modeling medieval Italian texts. Some significant examples of this
phenomenon can be found in the didactic moral genre between the end of
the 13th and the first half of the 14th century. The paper focuses on the vernacular
items transmitted by the Northern-Italian manuscript “Saibante-Hamilton
390” and the delta and eta versions of the moral philosophy compendium known as Libro di Costumanza. Particular attention is given to the influence
of Old French on both the lexical choices (gallicismi) and the morphosyntactic
structures. The study confirms the major role of the langue d’oïl literary production
as the most prestigious model for Italian prose works in the Middle Ages
On the Role of Competing Interactions in Charged Colloids with Short-Range Attraction
No full textIn this review, we discuss recent advances in the investigation of colloidal systems interacting via a combination of short-range attraction and long-range repulsion. The prototypical examples of this phenomenology are charged colloids with depletion interactions, but the results apply, to a large extent, also to suspensions of globular proteins, clays, and, in general, to systems with competing attractive (hydrophobic) and repulsive (polar) contributions. After a brief introduction to the problem, we focus on the three disordered states that characterize these systems: equilibrium cluster phase, equilibrium gel, and Wigner glass of clusters. We provide a comparison of their static and dynamic observables, mainly by means of numerical simulations. Next, we discuss the few available studies on their viscoelastic properties and on their response to an external shear. Finally, we provide a summary of the current findings and also raise the main open questions and challenges for the future in this topic
Multi-jet physics at high-energy colliders and TMD parton evolution
No full textWe discuss implications of the evolution of transverse momentum dependent (TMD) parton distributions on the structure of multi-jet states at high energies. In particular we analyze the theoretical systematics associated with multijet merging. We introduce a new merging methodology incorporating TMDs, illustrate its main features and present a comparison of our theoretical results with experimental measurements for Z-boson + jets production at the Large Hadron Collider (LHC)
Status of the FraISe facility and diagnostics system
No full textAt Laboratori Nazionali del Sud of INFN (INFN-LNS), the upgrade of the Superconductive Cyclotron (CS) and the building of a new fragment separator, named FraISe (Fragment In-flight Separator), are currently ongoing. FraISe will permit to produce Radioactive Ion Beams (RIBs) with intensity in the range of 103–107 pps, using the In-Flight Fragmentation method. The tuning and transport
process of RIBs represents a critical step to deliver high-quality beams. This process can be very time-consuming and it needs a dedicated diagnostics system measuring features of RIBs. In this paper, the status of the FraISe facility as well as the related diagnostics system are discussed
La cessione dei crediti salvo buon fine nello sconto bancario: prime riflessioni
Get PDFÈ noto come da tempo lo sconto bancario rappresenti un’operazione fondamentale per procurare quel serbatoio di disponibilità finanziaria necessario ad assicurare la continuazione dell’attività economica. Pur essendosi originato con l’intento di convertire in denaro titoli di credito di lunga scadenza, il contratto in oggetto è oggi – caduta in disuso la cambiale quale mezzo di pagamento delle transazioni economiche – frequentemente utilizzato dalle imprese per anticipare i loro crediti nei confronti della clientela e in ciò può essere rinvenuta la nuova finalità dell’istituto. Mentre una siffatta trasformazione si è inevitabilmente riflessa sulla funzione del medesimo, in quanto alla causa di finanziamento inizialmente tipica del contratto di sconto la letteratura scientifica più moderna ha di recente sostituito quella di liquidità, del tutto irrilevanti sono state invece le variazioni in ordine all’essenza giuridica del fenomeno. Il presente lavoro, nel concentrare i propri sforzi sulla figura del salvo buon fine ed in particolare della garanzia quale “croce” della cessione del credito, si propone di indagare, sotto il profilo dogmatico e strutturale, la natura giuridica di tale inciso e le ripercussioni che il medesimo ha sul funzionamento dell’intero negozio di sconto. L’obiettivo intorno al quale si incentra maggiormente la riflessione in esame è proprio quello di individuare nel mancato adempimento a scadenza da parte del debitore ceduto non un risultato indesiderabile del contratto idoneo a produrre – al pari di quanto accade con riferimento alla garanzia per la solvenza del debitore ceduto di cui all’art. 1267 c.c. – uno scioglimento del medesimo, ma l’attuazione, in forza della garanzia pura caratterizzante la clausola salvo buon fine, di un meccanismo giuridico che è in grado di originare in capo allo scontatario l’obbligo di corrispondere un indennizzo allo scontatore
Improving data analysis for size-segregated atmospheric aerosol samples
No full textSize-segregated atmospheric aerosol samples collected with cascade impactors can provide valuable information for the study of aerosol emission sources and processes, especially when size distributions of chemical compounds are retrieved. Nevertheless, such data are rare in the literature and, when available, they are often presented as discrete size distributions since data analysis is not straightforward, thus preventing to retrieve detailed modal structure information. For this reason, all the main steps for a robust analysis of size-segregated data are illustrated in this paper. The MICRON code was used to perform data inversion and a sensitivity test on the main input parameters (weights, smoothing parameter, and derivative order) was carried out to investigate how the output is affected by their variations. A method to fit the inverted distribution with log-normal functions and to validate the final output has been implemented and discussed through a case-study
Probing the morphology of dust particles in deep ice cores with light scattering
No full textThe size distribution and light extinction cross-section of airborne particles are among the climate proxies investigated in palaeoclimate research and required by radiative transfer models. The optical properties of the particles are acquired by a non-invasive, single-particle light scattering technique to characterise aeolian dust stored in deep polar ice core samples. The same method is applied to study alpine ice cores and firn cores. The particle-by-particle approach provides a comprehensive statistical analysis while overcoming the limitations imposed by low concentrations (∼ 101–103 ng/g). From a geometrical standpoint, dust particles deviate significantly from homogeneous spheres, as expected by many studies on mineral dust sources and ice core analysis. Features such as shape and structure prove to have greater importance than the particle refractive index in determining their radiative properties. By comparing experimental data to computationally inexpensive simulations, the main morphological properties of the particles can be inferred, such as the ratio between the axes in prolate particles and the porosity in isometric aggregate particles
Neutronographic investigation of water transfer in porous limestones
No full textIn this work, a comparative neutron radiography (NR) investigation was carried out on two different limestones, i.e., Pietra di Lecce and Pietra d’Aspra, widely employed as building materials during the Italian baroque epoch (XVI–XVII century). The effect of the application of two different mm-thick layer of consolidating products, namely nanosilica (Nano EstelR �) and nanolime (CaLoSiLR �), was evaluated with the aim to qualitatively determine the best protective effectiveness against artificial external stimuli. In this framework, NR represents a wellestablished approach capable to highlight, in a completely non-destructive way, the water suction process by spontaneous imbibition occurring inside porous building materials. Water dynamics represents a powerful marker both for the evaluation of the extent of the weathering process and for the quantification of the consolidating action of a specific product. In our case, the water flow through the porous network of investigated limestones indicated two types of porosity, as revealed by the different “smoothness” of the corresponding water content vs. sample height profiles. The effect of the application of commercially available consolidants was distinguished by monitoring the wetting front positions as a function of time. The obtained results give insight into the different coating/limestone interaction mechanisms, whose understanding appears particularly useful for the selection of a proper intervention plan to be applied
SiPM arrays test for the pSCT camera proposed for the CTA Observatory
No full textArrays of 16 pixels of the Near UltraViolet High-Density thirdgeneration (NUV-HD3) Silicon Photomultipiers (SiPMs) produced by Fondazione Bruno Kessler (FBK) in collaboration with Istituto Nazionale di Fisica Nucleare (INFN) have been assembled and characterised to equip the prototype Schwarzschild-Couder Medium-Sized Telescope (pSCT) camera proposed for the Cherenkov Telescope Array (CTA) Observatory. Each camera module is composed by four 16-pixel optical units coupled with a 64-channel front-end electronics module. The prototype camera has been equipped with 24 of 177 modules and is currently taking data at the Very Energetic Radiation Imaging Telescope Array System (VERITAS) Arizona, since January 2019. Nine of the 24 modules mount FBK NUV-HD SiPMs. Latest results on their characterisation and performance will be shown. pSCT was able to detect its first light soon after the inauguration, in January 2019. A dedicated campaign for the Crab Nebula observation conducted in January 2020 led to the Crab detection. Results of this detection will be shown
