1. Validação do processo de esterilização por óxido de etileno para determinar o tempo de aeração em frascos enterais / Validation of the sterilization by ethylene oxide to determine the aeration time in bottles enteral
Para estabelecer a segurança da esterilidade nos frascos enterais faz-se necessário a validação do processo de esterilização. O objetivo deste estudo foi determinar o tempo de aeração residual em frascos enterais esterilizados por óxido de etileno. Foram utilizados 120 frascos enterais para realizar da qualificação física, microbiológica e quím

2. Cell toxicity in vitro analysis of PVC tubes consecutively submitted to gamma-rays and ethylene oxide sterilization / Análise in vitro da toxicidade celular de tubos de PVC esterilizados consecutivamente em raios gama e óxido de etileno
In 1967, a letter sent to the British Medical Journal reported that the re-sterilization with Ethylene Oxide (EtO) of previously irradiated Polyvinyl Chloride (PVC) formed large amounts of ethylene chlorohydrin, a highly toxic compound. Even though it did not present measured data, this letter initiated a controversy that still divide the opinion of research

4. Remoção de carbono e nitrogênio em reator de leito móvel submetido à aeração intermitente / Nitrogen and carbon removal in moving bed reactor operated under intermittent aeration
The operating conditions for the combined removal of nitrogen and organic matter in moving- bed biological reactor were investigated. Two bench-scale reactors, two liters each, were operated under intermittent aeration and continuously fed with synthetic wastewater containing ammonia nitrogen (90 to 110 mg/L) and molasses as organic carbon source (COD of 450

5. Desenvolvimento e calibração de um tanque de reaeração equipado com grade oscilante / Development and calibration of a reaeration tank equipped with oscillating grids
Este trabalho apresenta a calibração e o desenvolvimento de um tanque de reaeração, equipamento que gera turbulência com intensidade controlável por meio de grade oscilante. Foram realizadas adequações ao projeto inicial de construção do tanque, idealizado por ROMA, onde se buscou o equilíbrio e as limitações de funcionamento para que, em futuro

6. Effect of calcium on enzymes of antioxidant system in maize (Zea mays L.) âSaracuraâ â BRS-4154 plantlets submitted to how oxygen availability / Efeito do cÃlcio em enzimas do sistema antioxidante em plÃntulas do milho (Zea Mays L.) âSaracuraâ â BRS-4154 submetidas à baixa disponibilidade de oxigÃnio
The present work aimed to verify the influence of calcium in the ADH and antioxidant system enzymes, like SOD, CAT, APX and GR, in maize seedlings "Saracura" during the period of low availability of oxygen and the onset of pos-stress recovery. In this research there were used maize plantlets, âSaracuraâ (BRS-4154), cycle 17. The germination was made in ger

7. Study of turbulent parameters and your relation with the coefficient reaeration with the use of the photographic technique / Estudo de parâmetros turbulentos e sua relação com o coeficiente de reaeração com o uso da técnica fotográfica
The importance given to the parameters of quality of the water, mainly in the last decades, it justifies the accomplishment of this work, that it investigates the relation of some turbulent parameters with the re-aeration coefficient, K IND.2 , through two different techniques of measure: the optic method and the photographic technique. The optic method rela

8. Metabolismo de nitrogenio em plantas de soja [Glycine max (L.) Merr. cv IAC-17] submetidas a deficiencia de O2 no sistema radicular
The soybean (Glycine max (L.) Merr.) is among the most frequently used models to study O IND.2 deficiency in the root system of plants. However, few studies have focussed on waterlogging of the root system and its effects on the metabolic content of the roots, especially nitrogenous compounds, and their means of transportation through the xylem and phloem.

9. Re-Aeration following Hypoxia or Anoxia Leads to Activation of the Antioxidative Defense System in Roots of Wheat Seedlings1
The response of the ascorbate-glutathione cycle was investigated in roots of young wheat (Triticum aestivum L.) seedlings that were deprived of oxygen either by subjecting them to root hypoxia or to entire plant anoxia and then re-aerated. Although higher total levels of ascorbate and glutathione were observed under hypoxia, only the total amount of as

10. Aspergilloma in the frontal sinus expanding into the orbit.
A case of primary frontal sinus aspergilloma in a 79 year old non-immunocompromised woman, who presented with a right sided pyocele expanding into the orbit, is presented. The low susceptibility of the frontal sinus is probably related to the brachycephalic shape of the human skull which locates this sinus far anterosuperiorly to the nasal cavity. In human f

11. Susceptibility of Lipopolysaccharide Mutants to the Bactericidal Action of Human Neutrophil Lysosomal Fractions
Acetate extracts of purified human neutrophil granules (a mixed population containing specific and azurophil granules) were dialyzed against phosphate-buffered saline (pH 7.0) and tested for bactericidal activity against smooth parent and rough mutant, gram-negative bacteria. Rough (Re) mutants of Escherichia coli, Salmonella typhimurium, and Salmonella minn

12. Mineralization of the sulfonated azo dye Mordant Yellow 3 by a 6-aminonaphthalene-2-sulfonate-degrading bacterial consortium.
Under anaerobic conditions the sulfonated azo dye Mordant Yellow 3 was reduced by the biomass of a bacterial consortium grown aerobically with 6-aminonaphthalene-2-sulfonic acid. Stoichiometric amounts of the aromatic amines 6-aminonaphthalene-2-sulfonate and 5-aminosalicylate were generated and excreted into the medium. After re-aeration of the culture, the
