A basic need theory approach to problematic Internet use and the mediating effect of psychological distress
2015
The Internet provides an easily accessible way to meet certain needs. Over-reliance on it leads to problematic use, which studies show can be predicted by psychological distress. Self-determination theory proposes that we all have the basic need for autonomy, competency, and relatedness. This has been shown to explain the motivations behind problematic Internet use. This study hypothesizes that individuals who are psychologically disturbed because their basic needs are not being met are more vulnerable to becoming reliant on the Internet when they seek such needs satisfaction from online activities, and tests a model in which basic needs predict problematic Internet use, fully mediated by p…

Mechanisms of cell death in canine parvovirus-infected cells provide intuitive insights to developing nanotools for medicine
2010
Jonna Nykky, Jenni E Tuusa, Sanna Kirjavainen, Matti Vuento, Leona GilbertNanoscience Center and Department of Biological and Environmental Science, University of Jyväskylä, FinlandAbstract: Viruses have great potential as nanotools in medicine for gene transfer, targeted gene delivery, and oncolytic cancer virotherapy. Here we have studied cell death mechanisms of canine parvovirus (CPV) to increase the knowledge on the CPV life cycle in order to facilitate the development of better parvovirus vectors. Morphological studies of CPV-infected Norden laboratory feline kidney (NLFK) cells and canine fibroma cells (A72) displayed characteristic apoptotic events. Apoptosis was f…
Analysis of structural plasticity in the adult and adolescent mouse brain. Effects of erythropoietin
2019
INTRODUCCIÓN Los organismos están sujetos diariamente a cambios que ocurren en su entorno y dentro del propio organismo. Estas entradas de información del medio externo e interno son integradas y analizadas por el organismo con el fin de dar una respuesta adecuada que asegure la supervivencia. Es crucial, por lo tanto, que el sistema responda de forma apropiada al amplio abanico de cambios y demandas que acontecen a lo largo de la vida del organismo. En este aspecto, el sistema nervioso se destaca como uno de los principales sistemas encargados de mantener el orden interno y reaccionar con cambios adaptativos a los eventos que lo rodean. Un funcionamiento aberrante del sistema da lugar a la…
Vasseuromys rambliensis sp. nov. (Gliridae, Mammalia) from the Ramblian (Lower Miocene) of the Tudela Formation (Ebro basin, Spain)
2012
In this paper, a new species of Vasseuromys, V. rambliensis sp. nov., from the locality Pico del Fraile 1 (PF1, Ebro basin, North-eastern Spain) is described. The association of Ligerimys, Peridyromys murinus and Simplomys simplicidens, and the absence of Eucricetodon and Democricetodon, allows dating of the PF1 locality as Late Ramblian (Early Miocene, MN3, local zone A). Main diagnostic features of V. rambliensis sp. nov. are the presence of four extra ridges in the lower molars, a very reduced anterotropid and a metaloph connected to the posteroloph and not to the protocone. The size and morphology of V. rambliensis sp. nov. are very close to V. bacchius from the upper part of unit MN2, …
Non-linear analysis of plane steel prestressed truss in fire
2002
The concept of analysis of 2-D static loaded prestressed steel trusses till failure during fire using a modified method of forces is presented. Failure of steel trusses in fire is based on the criterion of stresses. Behaviour of steel is described by non-linear constitutive model (based on hypo-elastic Ramberg-Osgood formula and Dorn creep theory) and Plem proposition (for string). Both models are approximated in calculations by hyperbolic Norton-Bailey rule. Fire simulates thermal force as an action of high temperature that increases linearly up to some level. The complete formulation of this method is illustrated by the algorithm of model parameters identification. Analysis of results for…
Criteri per l’analisi post-danno – Criteria for post-damage analysis.
2010
Gli elementi non-strutturali risultano assai più vulnerabili al sisma delle strutture, così come reso evidente dai terremoti che nell’ultimo decennio hanno colpito il nostro paese. Il danneggiamento di tali elementi, oltre a mettere a serio rischio la sicurezza degli edifici, e dunque l’incolumità, spesso rende diseconomici, disagevoli o addirittura impraticabili gli interventi di riparazione degli edifici. Ciò anche quando questi sono a struttura intelaiata e progettati e realizzati con criteri antisismici e le strutture non hanno subito danni di rilievo. D’altronde il comportamento sismico degli elementi non strutturali è stato lungamente trascurato e dall’analisi dello stato dell’arte in…
Seismic prevention and rahabilitation of nonstructural elements. Criteria to define a post-seismic damage analysis procedure

2010
Verificata la mancanza di attenzione alla prevenzione e riabilitazione sismica degli elementi non strutturali nella ricerca scientifica e nella normativa tecnica italiana, è stato avviato un progetto di cooperazione internazionale tra l’Università di Palermo e l’Università di Berkeley dal titolo “Prevenzione e riabilitazione sismica nonstrutturale.Confronto fra due culture di prevenzione sismica al fine di redigere linee guida per un manuale d’uso degli edifici scolastici”, finanziato nell’ambito del programma CoRI 2005/2006 dell’Ateneo di Palermo. Tra le varie attività previste durante la permanenza del partner straniero a Palermo è stato organizzato un workshop, che ha visto coinvolto un …
A Simple, High-Yield Method for Assessing Structural Novelity
2013
The structural dimension of music plays an important role in its affective appreciation. One particular aspect is related to the temporal succession of moments, each characterized by particular musical properties. One classical approach in computational modelling of this aspect is based on similarity matrix representations, where successive states are visualized by successive squares along the main diagonal, bearing some resemblance to checkerboards. One referential method estimates a so-called novelty curve, representing the probability along time of the presence of transitions between successive states, as well as their relative importance. Novelty is traditionally computed by comparing –…
