this study reports the concentrations of important tracers of the marine environment, 210po and210pb, in different matrices from field samples collected at central adriatic sea (italy), a non-contaminatedmarine ecosystem. 210po concentration appears to decrease with increasing distance from the coast and asignificant difference in 210po concentrations in seawater samples at two different depths...

A method of analyzing the detergency of various soils by assuming normal distributions for the soil adhesion and soil removal forces was developed by considering the relationship between the soil type and the distribution profile of the soil removal force. The effect of the agitation speed on the soil removal was also analyzed by this method. Washing test samples were prepared by soiling fabric...

A monitoring campaign in a horizontal subsurface flow constructed wetland under the influence of transient loads of flow-rate, organic matter, nitrogen and suspended solids showed an irregular removal of COD and TSS and lower both removal efficiencies and mass removal rates than the ones observed in other studies for similar operating conditions. This circumstance is associated to the presence ...

Multi-pollutant control technologies will become more important in the future. This new membrane wet electrostatic precipitator (WESP) system is ideally suited to, and very cost effective for, removing PM2.5, SO3 and Hg after limestone wet flue gas desulphurization (WFGD) scrubbers in the utility industry. Several coal-fired utilities have been experiencing increased SO3 emissions from their ex...

Removal of particulate materials from the retinal surface is somewhat difficult during small gauge vitrectomy. Simple injection of balanced salt solution into the vitreous cavity in a controlled manner using a connector tubing between the syringe and needle can produce enough turbulence to float the deposited material and remove it.

Fibers represent a type of structure great interest in catalysis since they combine high area to volume ratio and can be fabricated from many types materials, such as ceramic oxides, polymers, alloys. They used isolated form or structured, the case papers synthesized this work, following modified papermaking technique. The addition cationic anionic polyelectrolytes improved retention fibers dur...

This is a review of acid aluminum phosphate for the binding and coating of materials. The acid aluminum phosphate in the form of a solution obtained by dissolving aluminum hydroxide in phosphoric acid, with a P/Al molar ratio of 23, is effective for the binding of fibrous or particulate materials. Porous ceramic articles are made using this binder by wet forming, followed by heat treatment. The...
