Background and aims: The aluminum-containing compounds are used as glaze in tile and ceramic production plants. It means that the workers working in these plants are in direct exposure to aluminum-containing compounds. The aim of this study was to assess the potential damages caused by aluminum among tile plant workers. Methods: In this cross-sectional study, 60 workers whom were in direct exp...

During air–slip direct chill casting of aluminum alloys, uneven or low air pressure areas at the surface of the porous graphite ring mold, can cause the metal to stick to the graphite ring and produce traces along the billets called vertical drags (VD). To prevent this type of defect, it would be an advantage to decrease the wettability of the graphite ring. It has been shown that nanostructure...

conclusions the results of this study show that it is possible to remove nitrate, and its intermediates from waste water. regarding the desirability of the process, the field scale study is proposed. results the results showed that by applying electric current of 0.14 a for 120 minutes, the nitrate content would reduce down to 97%. the obtained r2 for the nitrate removal model was higher than 0...

Anode carbon residue is produced in the production of electrolytic aluminum. Its properties need to be studied for secondary utilization. In this paper, mineralogy anode from an aluminum plant Guizhou was studied. The chemical composition, structure, mineral occurrence state main elements, etc, investigated. results show that: mainly composed 14 minerals such as cryolite, cryolithionite, elpaso...

Human Serum albumin as well as other biological products prepared by blood fractionation for clinical purposes, was found to contain different amount of aluminum in different commercially available human albumin solutions. It has been reported that interaction of chemicals with the container material can occur during plasma collection, manufacture and storage, so aluminum is introduced into alb...

introduction: dentin hypersensitivity (dh) is characterized by tooth pain arising from exposure of dental roots. in this study the efficiency of neodymium yttrium-aluminum-garnet (nd:yag) laser in association with graphite on dentinal surface changes as the alternative to the treatment of dh was evaluated. methods: sixteen noncarious human third molars were collected and sectioned into 5 parts ...

Abstract: Dolomite based refractories are widely used in Iranian steelmaking plants. In the present research, wear and corrosion of refractories used in steel-making converter lining in Esfahan Steel Company was studied. Post-mortem analysis of refractories clarified that the wear started with oxidation of carbon followed by chemical corrosion. Iron oxide from slag reacted with calcia, resu...

Experimental measurement of nuclear heating rates has been carried out in a simulated D-T fusion neutron environment from 1989 through 1990 under the USDOE/JAERI collaborative program at the Fusion Neutronics Source Facility. The microcalorimetric technique has been employed for online measurements. Small probes of materials have been irradiated in close vicinity of a rotating target. A typical...
