Methodology for Analyzing Dissolved Oxygen Consumption in Benthic Chambers
(American Society of Civil Engineers, 2015)
Dissolved oxygen (DO) consumption in the sediments of natural aquatic ecosystems occurs by mass flux across the water-sediment interface. This mass flux is determined as either the rate of oxygen consumption in the sediment ...
Fire resistance of wood impregnated with soluble alkaline silicates
(Hindawi Publishing Corporation, 2007-12-02)
The aim of this paper is to determine the fire performance of wood panels (Araucaria angustifolia) impregnated with soluble alkaline silicates. Commercial silicates based on sodium and potassium with 2.5/1.0 and 3.0/1.0 ...
Fire retardant impregnants for woods based on alkaline silicates
The aim of this paper was to determine the fire performance of wood panels (Araucaria angustifolia) impregnated in a pressure vessel with post-cured alkaline silicates (water glasses). Several commercial silicates based ...
Zinc borates as flame-retardant pigments in chlorine-containing coatings
(Elsevier Science Sa, 2001-06)
This paper discusses the influence of zinc borates with molecular formulas of 2ZnO·3B2O3·3.5H2O and 2ZnO·3B2O3·7.5H2O used for substituting antimony trioxide on the performance of chlorinated alkyd, flame-retardant coatings. ...
Sterilization of Medical Devices by Ethylene Oxide, Determination of the Dissipation of Residues, and Use of Green Fluorescent Protein as an Indicator of Process Control
Ethylene oxide (EO) is used to sterilize Oxygenator and Tubing applied to heart surgery. Residual levels of EO and its derivatives, ethylene chlorohydrin (ECH) and ethylene glycol (EG), may be hazardous to the patients. ...
Limitaciónes intracapsulares en dos especies de gastropodos con modos de desarrollo contrastantes: crepidula fornicata y c. Coquimbensis
Parental protection in aquatic systems is usually related to the aggregation of the offspring. Many studies suggest that oxygen and food availability to the aggregation are important limiting factors affecting survival and ...
Estudo analítico de um demonstrador da tecnologia da combustão supersônica
(Universidade Federal do Rio Grande do NorteBrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM ENGENHARIA MECÂNICA, 2020-06-29)
The hypersonic airbreathing propulsion based on supersonic combustion (scramjet technology) has high potential to be use as intermediate stage for the aerospace vehicles. Using the atmospheric air as the working fluid ...
Electrochemical degradation of Azo-dye Acid Violet 7 using BDD anode: effect of flow reactor configuration on cell hydrodynamics and dye removal efficiency
Abstract: The electrochemical oxidation of synthetic textile effluent containing Azo-dye Acid Violet 7 (200 mg L−1) was investigated using planar disk electrodes placed in a one inlet–outlet (I–O) cylindrical reaction ...
