Role of nitric oxide in glioblastoma therapy: another step to resolve the terrible puzzle?

Glioblastoma Multiforme, the most common and aggressive primary brain tumor, remains incurable despite of the advent of modern surgical and medical treatments. This poor prognosis depends by the recurrence after surgery and intrinsic or acquired resistance to chemotherapy and radiotherapy. Nitric oxide is a small molecule that plays a key roles in glioma pathophysiology. Many researches showing that NO is involved in induction of apoptosis, radiosensitization and chemosensitization. Therefore, NO role, if clarified, may improve the knowledge about this unsolved puzzle called GBM

Effect of mixing time and temperature on the viscosity of asphalt rubber containing waxy additives.

Crumb rubber from end-of-life tyres can be employed in the production of asphalt rubber binders by means of the so-called “wet” mixing technology. However, since the physical and chemical interaction between rubber particles and neat binder causes a significant viscosity increase, corresponding bituminous mixtures require higher mixing and compaction temperatures than those of standard mixtures. Such a need leads to the overall increase of energy consumption and to the emission of a greater quantity of fumes during laying operations, thus partially reducing the eco-friendly character of asphalt rubber technology. The problems highlighted above can be in part balanced by making use of viscosity-reduction additives. In the research work described in this paper, the effects of a waxy additive on the flow properties of asphalt rubber were studied by means of viscosity measurements. Tests were carried out by considering both commercial and laboratory-prepared asphalt rubber products. Factors which were analyzed during the experimental investigation included mixing technique, time and temperature. Obtained results suggest that additive efficiency is strongly related with asphalt-rubber mixing time and temperature. When these two parameters are kept constant, a similar viscosity reduction is recorded for both the commercial and laboratory asphalt-rubber

Tronci, Automated analysis of timed security: A case study on web privacy

Abstract. This paper presents a case study on an automated analysis of real-time security models. The case study on a web system (originally proposed by Felten and Schneider) is presented that shows a timing attack on the privacy of browser users. Three different approaches are followed: LH-Timed Automata (analyzed using the model checker HyTech), finite-state automata (analyzed using the model checker NuSMV), and process algebras (analyzed using the model checker CWB-NC). A comparative analysis of these three approaches is given
