Bacterial biofilms: a challenge in the discovery of new anti-infective agents.

2010

The ability to form a biofilm, bacterial communities able to grow on surfaces and surrounded by an extracellular polymeric substance biofilm agents.Our research group focused on discovering of novel chemical agents of potential therapeutic utility in the treatment of staphylococcal biofilm-associatedinfections by screening novel compounds (synthetic or natural). In a recent study, the antistaphylococcalbiofilm activity of pyrrolomycins C,D, F1, F2a, F2b, F3 a family of halogenated pyrroles which are naturally produced byActinosporangium vitaminophylum and of the synthesized related compounds I, II, III were investigated and compared (Schillaci et al, 2010). We also focused on marine inverte…

Optical quality of hyperopic and myopic phakic intraocular lenses

2013

Aims: To assess and compare the optical quality of the myopic and hyperopic implantable collamer lens (ICL) from its wavefront aberrations for different powers and pupil diameters. Settings and Design: Prospective study. Material and Methods: The wavefront aberrations of two myopic (−3 and −6 diopters (D)) and two hyperopic V4b ICLs (+3 and +6D) were measured in vitro . To assess and compare the optical quality of different powers of ICLs, we analyzed the root mean square (RMS) of total higher order aberrations (HOAs), trefoil, coma, tetrafoil, secondary astigmatism, and spherical aberration at 3- and 4.5-mm pupil. In addition, the point spread functions (PSFs) of each ICL evaluated were ca…

Economic Aspects of Hybrid Cloud Infrastructure: User Organization Perspective

2012

Adoption of cloud infrastructure promises enterprises numerous bene- ts, such as faster time-to-market and improved scalability enabled by on-demand provisioning of pooled and shared computing resources. In particular, hybrid clouds, by combining the private in-house capacity with the on-demand capacity of public clouds, promise to achieve both increased utilization rate of the in-house infrastructure and limited use of the more expensive public cloud, thereby lowering the total costs for a cloud user organization. In this paper, an analytical model of hybrid cloud costs is introduced, wherein the costs of computing and data communication are taken into account. Using this model, a cost-e c…

Stili difensivi, alessitimia e percezione della qualità della vita in pazienti affette da neoplasia al seno

2011

Introduzione: Il presente lavoro indaga la qualità delle reazioni emotive e psicologiche delle pazienti affette da cancro mammario, sottoposte a intervento chirurgico e in diversi stadi di malattia. Metodologia: Il campione è composto da 110 pazienti così suddivise: 40 in follow-up, 41 sottoposte a chemioterapia adiuvante, 29 metastatiche. Strumenti: Defense Mechanisms Inventory (DMI, Ihilevich e Gleser, 1986), Toronto Alexithymia Scale (TAS-20, Taylor GJ,1992), EORTC QLQ-C30-BR23 (Fayers PM et al 1998). Risultati: Nei tre gruppi si rivela differenza alle scale F1 (p<.01), F2 (p<.03), F3 (p<.00) della TAS-20 e QoL (p<.02) e FS (p<.01) dell’EORTC. Al DMI si riscontrano punteggi più elevati a…

DYNAMIC ANALYSIS OF MOTORCYCLE BEHAVIOUR ON THE ROAD WITH STEERING PLATE STRUCTURAL OPTIMISATION

2005

On the structural optimization in presence of base isolating devices

2012

The minimum volume design of plane frames constituted by elastic perfectly plastic material and subjected to appropriate combinations of fixed, cyclic and dynamic loads is studied. The influence on the design, in terms of cost (volume) and behavioural features, of seismic protecting devices is particularly focused. The considered protecting device is a lead rubber bearing base isolation system. Two optimal design problem formulations are proposed for the structure with or without the protecting device, both based on the so-called statical approach. The minimum volume frame is reached accounting for three different resistance limits: the purely elastic limit, the (elastic) shakedown limit an…

COMMUNITY DETECTION IN TRIPARTITE NETWORKS OF UNIVERSITY STUDENT MOBILITY FLOWS

2021

The purpose of this study is to explore how the multimode network approach can be used to analyse network patterns derived from student mobility flows. We define a tripartite network based on a three-mode data structure, consisting of Italian provinces of residence, universities and fields of study, with student exchanges representing the links between them. A comparison of algorithms for detecting communities from tripartite networks based on modularity optimization is provided, revealing relevant information about the phenomenon under analysis over time. The findings are applied to a real dataset containing micro-level longitudinal information on Italian university students’ careers.

Omaa paikkaa etsimässä : edistyneisyys suomea toisena kielenään puhuvien kokemana

2022

This article takes up a central question of Kirsti Siitonen’s dissertation – how advancedness in Finnish as a second language can be characterized – and investigates it from the perspective of research terminology as well as the lived experience of language users. We first discuss how and with what implications advanced learners of Finnish have been referred to in the research literature, i.e. whether they have been regarded as learners, speakers or other kinds of language users. Applying a small stories approach to interview data from different research projects, we then explore what advancedness means to such language users themselves. We conclude that advanced learners navigate a complex…

Effect of perceived organizational support on psychological capital - A study of IT industries in Indian framework

2015

In today's business environment, positive psychology and social exchange relationship have been attained great interest for research. Psychological Capital (PsyCap) is an individual's positive psychological state of development and is characterized by optimism, hope, resilience and self- efficacy. The commitment of employees directly depends on the commitment of organization towards their employees i.e. norms of reciprocity and social exchanges work between employee and organization. Perceived organizational support (POS) indicates the perception of employees that at what extent they are cared and valued by organization. The present study was conducted to identify the relationship between P…
