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 ...

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 ...

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 ...

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. ...

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. ...

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 ...

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 ...

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 ...
