1. Validated analytical study of the effect of Lycopene on the pharmacokinetics of Paracetamol and Chlorzoxazone in rats
Lycopene was reported to influence some cytochrome P450 enzymes activity. The present study investigates the effect of lycopene on the pharmacokinetics of paracetamol and chlorzoxazone. Lycopene (20 mg/kg) was intra-peritoneally administered to two groups of rats for eight consecutive days and two other groups were given vehicle. On the eighth day, chlorzoxa

5. Uma arquitetura de comunicação oportunística
Mobile computing devices often present high processing power and include several wireless network interfaces. 4G networks promise to provide a unified IP based infrastructure with QoS and security support for the communications using such devices. Transmission delays, and network disruptions, however, are often common when considering the current transmissio

6. Uma arquitetura de controle de qualidade de serviço aplicada a redes heterogêneas e serviços convergentes. / An architecture for QoS control applied to heterogeneous networks and convergent services.
One of the targets of the next generation communication systems is to provide access to any service, to any user, anytime, anywhere, regardless the access network technology or type of user device (mobile phone, PDA, personal computer, and so on). This scenario is called convergence of services by heterogeneous networks, and in such scenario quality of servi

8. 3D routing with context awareness
The emergence of low-cost, wireless network interfaces in the market and the ever increasing growth in demand of mobile devices (such as SmartPhones, PDAs, Internet Tablets and Laptops) enabled scenarios where network services for mobile users may exist in an ad hoc fashion, with no pre-existing communications infrastructure. However, the creation of such dy
