Objective: To investigate the correlation between of the level of sedation with time on mechanical ventilation (MV). Methods: Cross-sectional study with retrospective documentary survey by analysis of medical records of patients admitted to the ICU of the Gurupi Reference Hospital (GRH) in the period February to July 2012. The data investigated in the report nursing care systematization was time on MV and sedation level using the Ramsay scale. Results: The study included 63 records, with a mean age of 63 ± 20 years, 63.5% men. The mean hospital stay was 12 ± 9 days and stay in MV was 7 ± 5 days. The average level of sedation according to the Ramsay scale was found to be 4.8 ± 0.9. No correlation was found between the level of sedation and length of stay in VM. Conclusion: It is concluded that for patient...

Considerando a grande representatividade que a escrita alfabética tem em nossa sociedade grafocêntrica, procura-se pensar meios em que o professor pode atuar na zona de desenvolvimento proximal de seus alunos. Com isso, almeja-se maturar o conhecimento prévio que os alunos de Educação Infantil têm sobre o livro e a leitura por meio da leitura fruição, aqui entendida com uma prática desprovida de obtenção de resultados, ou seja, o ler por gosto de ler, para a partir dessa prática cotidiana, os alunos de Educação Infantil se sentirem próximos e interessados pela leitura e procurem a mesma por seus próprios gostos. Palavras-chave: Leitura fruição; Mediação pedagógica; Perspectiva histórico-cultural.

Algorithms have been developed to identify and address these problems in the data. The methods have been tested on cosmic ray muon data, calorimeter noise data, and single beam data collected with CMS in 2008. The noise rejection algorithms can be applied to LHC collision data at the trigger level or in the offline analysis. The application of the algorithms at the trigger level is shown to remove 90% of noise events with fake missing transverse energy above 100 GeV, which is sufficient for the CMS physics trigger operation.

Cosmic ray muons were detected in the muon chambers and used to trigger the readout of all CMS sub-detectors. About 15 million events with a muon in the tracker were collected. The efficiency of hit and track reconstruction were measured to be higher than 99% and consistent with expectations from Monte Carlo simulation. This article details the commissioning and performance of the Silicon Strip Tracker with cosmic ray muons.
