IL TRATTAMENTO RIABILITATIVO IN ACQUA NEL BAMBINO CON LESIONE DEL PLESSO BRACHIALE DI TIPO SUPERIORE DA FRATTURA DI CLAVICOLA
2008
La paralisi del plesso brachiale continua a rappresentare una drammatica conseguenza dei parti complicati. Il trattamento riabilitativo in queste lesioni è fondamentale in quanto le forme non trattate hanno una prognosi sfavorevole. Il trattamento in acqua ha permesso il normale sviluppo delle attività psico motorie.
Go Cashless! Mobile Payment Apps Acceptance in Developing Countries: The Jordanian Context Perspective
2022
Despite the expanding global usage of mobile phones in money transactions, the adoption of mobile payment systems in Jordan remains slow. This study employed the technology acceptance model (TAM) to identify the factors with a potential impact on mobile payment systems acceptance. The impact of perceived privacy (PP) and the mediating function of perceived certainty (PC) on the behavioral intention (BI) of mobile payment systems among Jordanian ministries were examined. Data obtained from 270 respondents were analyzed using partial least-squares structural equation modeling (PLS-SEM). The empirical findings show a positive link between perceived usefulness (PU) and PC on the BI of mobile pa…
Decentralized Lightweight Group Key Management for Dynamic Access Control in IoT Environments
2020
Rapid growth of Internet of Things (IoT) devices dealing with sensitive data has led to the emergence of new access control technologies in order to maintain this data safe from unauthorized use. In particular, a dynamic IoT environment, characterized by a high signaling overhead caused by subscribers' mobility, presents a significant concern to ensure secure data distribution to legitimate subscribers. Hence, for such dynamic environments, group key management (GKM) represents the fundamental mechanism for managing the dissemination of keys for access control and secure data distribution. However, existing access control schemes based on GKM and dedicated to IoT are mainly based on ce…
UWSim-NET: An Open-Source Framework for Experimentation in Communications for Underwater Robotics
2019
The communication with the remotely operated vehicles (ROV) in underwater applications are usually based on umbilical cables. The increase in the number of ROVs in cooperative interventions motivates the interest in underwater wireless communications. They have a high impact in robotic applications because of their limited performance in underwater scenarios. In this work we present UWSim-NET, an extension of the simulator for underwater robotics UWSim, which is based on the Robot Operating System (ROS). UWSim-NET integrates a communications module based on Network Simulator 3 (NS3) that allows to model the physical and data link layers. Experiments demonstrating the capabilities of UWSim-N…
I codici in scrittura latina di Alessandro Farnese (1520-1589) a Caprarola e al Palazzo della Cancelleria nel 1589
2016
This article analyses the contents of the manuscripts in Latin script found at the Villa Farnese of Caprarola and the Palazzo della Cancelleria of Rome at the death of Cardinal Alessandro Farnese (1520-1589). They were inventoried by Claudio Tobalducci, librarian to the Cardinal; the inventories were edited by Francois Fossier. Although the manuscript collections seem neither organic nor systematically constituted by the Cardinal (the volumes were mainly borrowed from the great Farnese library in the Palazzo Farnese in Rome), the manuscripts were used by the Cardinal in the last years of his life. They shed light on at least some of the personal interests of this important ecclesiastical, p…
POLLEN MORPHOLOGY AND REPRODUCTIVE PERFORMANCES IN OPUNTIA FICUS-INDICA (L.) MILL.
2015
The fruits of Opuntia ficus-indica (L.) Mill., the most worldwide cultivated species of Cactaceae family, contain viable seeds (100-250) of large size. This characteristic influences the commercial quality of the fruit. The study of floral biology in Opuntia allows to understand the behaviour of the plant during reproductive phase and perhaps to distinguish clones with different fruits behaviour (with seed and seedless). The study resulted in a palynological characterization by optical and scanning microscopy (SEM), followed by a qualitative analysis on the male line with pollen viability and in vitro germination tests, in addition to a pollen-pistil interaction survey. The plant material c…
A parallel simulated annealing approach to the K shortest loopless paths problem
1997
The k shortest loopless paths problem is a significant combinatorial problem which arises in many contexts. When the size of the networks is very large the exact algorithms fail to find the best solution in a reasonable time. The aim of this paper is to suggest parallel efficient algorithms to obtain a good approximation of the solution to the k shortest loopless paths problem between two arbitrary nodes, when the network size is large. The heuristic used is known in literature as Simulated Annealing. Preliminary tests have been conducted for evaluating the validity of the proposed algorithms. The quality of the obtained results represents a significant base for further experimentations.
Transconjunctival sutureless 25-Gauge versus 20-Gauge standard vitrectomy: correlation between corneal topography and ultrasound biomicroscopy measur…
2009
Purpose: To determine the correlation between corneal shape changes and ultrasound biomicroscopy (UBM) findings at the sclerotomy sites in conventional 20-gauge (G) pars plana vitrectomy (PPV) and 25-G transconjunctival sutureless vitrectomy (TSV) and to compare the effectiveness of the two surgical methods. Design: Prospective, comparative, observational case series. Methods: Sixty consecutive eyes (60 patients) undergoing primary 3-port PPV. Thirty eyes (30 patients, group 20-G) were treated with 20-G standard PPV and 30 eyes (30 patients, group 25-G) with 25-G TSV. We compared healing of the sclerotomy sites in the two groups. We determined the correlation between corneal shape changes (…
Gibellina, la città che visse due volte : terremoto e ricostruzione nella Valle del Belice
2019
Il passato di Gibellina Nuova non è Gibellina Vecchia. Le storie delle due città sono profondamente diverse: il terremoto del 1968, che colpì con un’intensità del IX grado della scala Mercalli la Valle del Belice, è stato additato come causa della loro soluzione di continuità, ma i veri fattori che hanno determinato una frattura nella continuità storica vanno ricercati nelle politiche di intervento e nelle utopie urbanistiche che hanno orientato la ricostruzione. Il dopo-terremoto del Belice è stato il banco di prova della Prima Repubblica di fronte alle calamità naturali; dal fallimento delle sperimentazioni urbanistiche operate in vivo nel tessuto sociale, dalla dicotomia tra ricostruzion…
The full Boltzmann hierarchy for dark matter-massive neutrino interactions
2020
The impact of dark matter-neutrino interactions on the measurement of the cosmological parameters has been investigated in the past in the context of massless neutrinos exclusively. Here we revisit the role of a neutrino-dark matter coupling in light of ongoing cosmological tensions by implementing the full Boltzmann hierarchy for three massive neutrinos. Our tightest 95% CL upper limit on the strength of the interactions, parameterized via $u_\chi =\frac{\sigma_0}{\sigma_{Th}}\left(\frac{m_\chi}{100 \text{GeV}}\right)^{-1}$, is $u_\chi\leq3.34 \cdot 10^{-4}$, arising from a combination of Planck TTTEEE data, Planck lensing data and SDSS BAO data. This upper bound is, as expected, slightly …
