Current trends in CMPs indicate that the core count will increase in the near future. One of the main performance limiters of these forthcoming microarchitectures is the latency and high-demand of the on-chip network and the off-chip memory communication. To optimize the usage of on-chip memory space and reduce off-chip traffic several techniques have proposed to use the N-chance forwarding mec...

INTRODUCTION Bile and gallstones are spilled during 13% to 40% of all laparoscopic cholecystectomies. They can act as a septic focus and cause complications. We present 2 cases of perihepatic abscess formation due to dropped gallstones presenting some years later. Delayed diagnosis resulted in unnecessary investigations and had negative economic consequences. CASE DESCRIPTION In 1 patient a p...

An oil pipeline ruptured in May 1994 and 2 700 tons of crude oil leaked into the São Sebastião Channel, affecting several neighboring areas. A program for the monitoring of hydrocarbons in sediments, using the gas chromatography / flame ionization detector methodology, was being undertaken in the area at the time. The data obtained were compared to those of samples collected after the accident ...

In situ combustion of a water-in-oil emulsion layer supported on water is a complex process. In this paper, the combustion process of water-in-oil emulsion layers floating on top of a water body, as in the case of in situ burning of oil spilled at sea that has turned into emulsion, is modeled by using comprehensive mathematical treatment, and the results are compared with data obtained in our l...

Immune response is modulated by different substances that are present in the environment. Nevertheless, some of these may cause an immunotoxic effect. In this paper, the effect of organophosphorus pesticides (frequent substances spilled in aquatic ecosystems) on the immune system of fishes and in immunotoxicology is reviewed. Furthermore, some cellular and molecular mechanisms that might be inv...
