Epidermal growth factor (EGF), basic fibroblast growth factor (bFGF), insulin-like growth factor-I (IGF-I) and insulin (INS) are powerful mitogens and may regulate gene expression in cultured astrocytes by ADP-ribosylation process. Nuclear poly-ADP ribose polymerase (PARP) and mitochondrial monoADP-ribosyltransferase (ADPRT) are the key enzymes involved in(More)
The growing diffusion of pervasive collaboration environments and technical advancement of sensing technologies have fostered the development of a new wave of online services whose functionalities are based on users' physical position. Thanks to the widespread diffusion of mobile devices (e.g. cell phones), many services can be greatly enriched with data(More)
Third generation mobile networks rely on an architecture where a certain number of operation and maintenance centers handle a large amount of information about the network behavior. In this scenario, the amount of traffic-related data may become so large that even straightforward processing tasks, such as off-line querying, become a serious challenge. In(More)
eXecutIve suMMAry The widespread diffusion of online services provided by public and private organizations, firstly driven by e-commerce and more recently by e-government applications, has stressed the need of secure ways to authenticate users who need to access online resources. The huge number of resources accessible on the Web leads to different(More)
In mobile networks many new services are being planned based on the knowledge of mobile terminals location. Mobile terminal geolocation is aimed at using the cellular network infrastructure and protocols in order to provide a reliable and accurate estimate of mobile terminals positions without the need for global positioning systems such as GPS. In this(More)
Today's pervasive collaboration environments, together with the recent technical enhancements of sensing technologies have boosted the development of a new branch of online services whose functionalities are based on their users' physical position. Many new services are being planned which conveniently exploit the knowledge of users' location, determined(More)
This paper presents the design and the architecure implementation of a system, which provides an user access control framework by means of multiple authentication methods. The user description is provided according to the semantic web standard architecture, based on two different kind of metadata: profile and context. Biometric technology guarantees the(More)
