1. Técnicas de processamento não linear de sinais aplicadas à investigação de limitações práticas do procedimento de ventilação mecânica não invasiva
Individuals with respiratory system dysfunctions or who are recovering from complex surgeries may have difficulty to sustain spontaneous breathing. The mechanical ventilation is a clinical procedure that supports ventilation until the patient is recovered. Noninvasive mechanical ventilation is especially remarkable as it can be used outside the hospital, in

2. Projeto, construção e calibração de um dosador de poeira para ensaios de elementos filtrantes / Project, construction and calibration of a dust feeder for filter elements tests
O desenvolvimento de novos filtros de passagem de ar para atender as mais diversas exigências de projeto e ambientais é um grande desafio. Para o completo estudo das características projetuais de filtros são necessários simulações e experimentos em bancada. Assim, esse trabalho relata o projeto, a construção e calibração de um dosador de poeira pa

3. Airborne environmental endotoxin: a cross-validation of sampling and analysis techniques.
A standard method for measurement of airborne environmental endotoxin was developed and field tested in a fiberglass insulation-manufacturing facility. This method involved sampling with a capillary-pore membrane filter, extraction in buffer using a sonication bath, and analysis by the kinetic-Limulus assay with resistant-parallel-line estimation (KLARE).

4. Evaluation of exposure to polycyclic aromatic hydrocarbons in a coke production and a graphite electrode manufacturing plant: assessment of urinary excretion of 1-hydroxypyrene as a biological indicator of exposure.
OBJECTIVES--Characterisation of the airborne concentration of 13 polycyclic aromatic hydrocarbons (PAHs) at various workplaces in a graphite electrode and a coke production plant. Validation of the urinary excretion of 1-hydroxypyrene (hydroxypyrene) as a biological marker of exposure to PAH. DESIGN--Cross sectional study of workers exposed to PAHs (106 in t
