Il progetto necessario: Pasquale Culotta e il giornale della progettazione In Architettura (2010): un omaggio

2010

Raccolta di testimonianze e progetti del maestro cefaludese e di persone a lui vicine. Con questa pubblicazione, sorta di numero speciale, si intende dedicare un omaggio a Culotta. Ripercorrendo alcune delle tappe più importanti della sua attività, dal progetto per la Nuova sede della Facoltà di Architettura di Palermo al concorso per la chiesa di San Carlo Borromeo a Roma, attraverso la memoria e il contributo di chi ebbe occasione di lavorare e studiare con lui, si disegna il ritratto di un professionista, che ha visto nella ricerca costante e nella responsabilità etica del fare, il senso dell’essere architetto.

Ocular Motor Paroxysmal Events in Neonates and Infants: A Review of the Literature

2021

Abstract Background Ocular paroxysmal events can accompany a variety of neurological disorders. Particularly in infants, ocular paroxysmal events often represent a diagnostic challenge. Distinguishing between epileptic and nonepileptic events or between physiological and pathologic paroxysmal events can be challenging at this age because the clinical evaluation and physical examination are often limited. Continuous polygraphic video-electroencephalography (EEG) monitoring can be helpful in these situations. Methods We review ocular paroxysmal events in newborns and infants. The aim is to improve clinical recognition of ocular paroxysmal events and provide a guide to further management. Usin…

Dielectric properties of solutions of antimony (III) halides in methanol

1993

The complex permittivities obtained by time domain reflectometry (TDR) measurements in the frequency range 0.1–15 GHz are reported for solutions of SbF3, SbCl3 and SbBr3 in methanol at 25°C. By increasing the concentration of the solutes, a marked increase of the main relaxation time and of the static permittivity of methanol is observed. These effects have been attributed to the ability of antimony (III) halides to strengthen the hydrogen bonding in methanol and to promote the shift of the dynamic equilibria among the various populations of hydrogen bonded methanol aggregates toward those characterized by a parallel orientation of neighboring dipoles. A second relaxation, occurring at low …

Consumers perception of food safety related risk in the italian market

2019

The aim of this paper is to define the factors affecting the consumers' perception on food risk associated to the consumption of products (i) containing food additives, (ii) obtained with the use of pesticides, and (iii) processed through novel food technologies, in relation to different socio-economic and demographic characteristics, the source of acquisition of information on food safety issues, and the place of purchase of food. The study is based on a sample of 392 consumers, living in Italy, and it uses three ordered probit estimation models to process data collected. Findings show that food risk perception is greater among youngsters, mainly for the additives and residual pesticides i…

Synergistic Effect of Physical Therapy Plus Pharmacological Therapy with Eperisone in Tension-Type Cervicalgia

2019

Background. This study assessed the effect of eperisone + physical therapy compared with physical therapy alone on the alleviation of pain and disability experienced by patients with tension-type cervicalgia. Methods. Patients with tension-type cervicalgia were randomized to eperisone + physical therapy (Group A) or physical therapy alone (Group B). Patients were assessed at baseline (T0), after 4-weeks’ treatment (T1), and at 2 months’ follow-up (T2). Outcome measures included the Numerical Rating Scale, the Italian version of the Neck Pain and Disability Scale, the Short Form-McGill Pain Questionnaire, and the Italian version of the Neck Disability Index. Results. Ninety-eight patients (5…

Identification In Silico and In Vitro of Novel Trypanosomicidal Drug-Like Compounds

2012

Atom-based bilinear indices and linear discriminant analysis are used to discover novel trypanosomicidal compounds. The obtained linear discriminant analysis-based quantitative structure–activity relationship models, using non-stochastic and stochastic indices, provide accuracies of 89.02% (85.11%) and 89.60% (88.30%) of the chemicals in the training (test) sets, respectively. Later, both models were applied to the virtual screening of 18 in-house synthesized compounds to find new pro-lead antitrypanosomal agents. The in vitro antitrypanosomal activity of this set against epimastigote forms of Trypanosoma cruzi is assayed. Predictions agree with experimental results to a great extent (16/18…

Distortions of [Sb2Cl10]4– Bioctahedra and Phase Transitions in the Chloroantimonate(III) (C3H5NH3)2[SbCl5]·(C3H5NH3)Cl

2007

Bis(allylammonium)pentachloroantimonate(III) - allylammonium chloride, (C3H5NH3)2[SbCl5] · (C3H5NH3)Cl, belongs to the chloroantimonate(III) organic-inorganic salts family. The DSC studies of this compound showed two anomalies at 181 K and at 223 K. Both are associated with phase transitions, which mainly occur due to ordering-disordering processes of the organic cations. Between 181 and 223 K the structure is incommensurate. The crystal structure was determined at 298 and 86 K. At both temperatures the crystal structure consists of (C3H5NH3)+ cations, anionic distorted [Sb2Cl10]4− units and isolated Cl− ions. In the room-temperature phase two out of three, and in the low-temperature phase …

Structural and vibrational study of cubic Sb2O3under high pressure

2012

We report an experimental and theoretical study of antimony oxide (Sb${}_{2}$O${}_{3}$) in its cubic phase (senarmontite) under high pressure. X-ray diffraction and Raman scattering measurements up to 18 and 25 GPa, respectively, have been complemented with ab initio total-energy and lattice-dynamics calculations. X-ray diffraction measurements do not provide evidence of a space-group symmetry change in senarmontite up to 18 GPa. However, Raman scattering measurements evidence changes in the pressure coefficients of the Raman mode frequencies at 3.5 and 10 GPa, respectively. The behavior of the Raman modes with increasing pressure up to 25 GPa is fully reproduced by the lattice-dynamics cal…

Synthesis and Characterization of Lead-Free (1-x)(K0.5Na0.5)Nb1-ySbyO3-xBaTiO3

2011

In this study lead-free ceramics with a formula (1-x)(K0.5Na0.5)Nb1-ySbyO3-xBaTiO3 have been synthesized and studied. XRD studies showed that all compositions have perovskite structure with monoclinic or tetragonal cell depending on substitution level. KNN ceramics with BaTiO3 have more homogeneous structure and increased density in comparison with pure KNN or antimony substituted KNN. Dielectric measurements revealed diffuse phase transition.
