Spray chilling technology (also known as spray cooling and spray congealing technology) has been widely studied and used in the pharmaceutical field. In the food industry, this technique is gaining interest and can become useful because functional food formulations can be developed. Spray chilling is a fat-based system, which involves the addition of the(More)
Virtual private networks (VPNs) are a popular and cost-effective means to build wide-area corporate networks, since they provide bandwidth, privacy and security for a fraction of the cost of private networks. However, establishing VPNs across different domains (inter-domain VPNs) is still a cumbersome task, requiring human- based negotiation between(More)
QoS adaptation is an important process in inter-domain service management, since it can guarantee the correct service provisioning when unexpected events occur. However, in inter-domain environments, the human interference and the manual-based operations hamper the deployment of expeditious mechanisms to adapt the QoS of the services. This paper presents an(More)
PURPOSE The reliability and construct validity of three age-adapted-intensity Yo-Yo tests were evaluated in untrained (n = 67) vs. soccer-trained (n = 65) 9- to 16-year-old schoolgirls. METHODS Tests were performed 7 days apart for reliability (9- to 11-year-old: Yo-Yo intermittent recovery level 1 children's test; 12- to 13-yearold: Yo-Yo intermittent(More)
Inter-domain QoS-aware service provisioning is still a complex task due to the Internet heterogeneity. It is necessary to overcome several obstacles in order to achieve a scenario where providers fully interact to satisfy all customer service requirements. Some of these obstacles are service class specification and service composition. This paper presents(More)
This paper implements and evaluates a multi-criteria approach to select appropriate service providers in a large scale multiprovider environment. This approach uses the Analytic Hierarchy Process (AHP) method in a Peer-to-Peer Service Overlay Network (P2P SON) composed of several service providers in order to select the most suitable one to deliver the(More)
Nocardiosis is an opportunistic infection which occurs mostly in immunocompromised individuals. Pulmonary presentation is the most frequent; however it can affect other parts of the body. Antibiotic treatment is usually prolonged to avoid relapses. The authors present a case report of a patient under prolonged immunosuppressive therapy for psoriatic(More)
Cooperation among service providers, network providers, and access providers in the Internet allows the creation of new services to offer to customers that are in other domains, thus increasing revenue. However, the Internet heterogeneous environment, where each provider has its own policies, infrastructure and business goals, hinders the deployment of more(More)
Hepatopulmonary syndrome is an important complication of chronic liver disease occurring in 16 24% of patients. It is characterized by an increase in alveolar -capillary gradient, with or without hypoxemia, due to intrapulmonary vasodilatation. The course of the disease is progressive and associated with increased morbidity and mortality. There is no(More)
Thoracic endometriosis is defined by the presence of endometrial tissue in the lungs or pleura, and is characterised by cyclic hemoptysis or recurrent hemothorax or pneumothorax occurring with the menstruation. Being a rare clinical entity, it is not always considered in the differential diagnosis when these symptoms are evaluated. The exams performed(More)
