Measurement of organic halogens in boiler feedwater

Materials of steam water cycles can suffer from corrosion induced by halide anions in feedwater. Organic halogen compounds in feedwater can be degraded and release halide anions under high temperature and pressure. Therefore it is necessary to be able to measure the organic halogen concentration. Existing measurements including Adsorbable Organic Halogens and Gas Chromatography are either not c...

Effects of halogens on European air-quality.

Halogens (Cl, Br) have a profound influence on stratospheric ozone (O3). They (Cl, Br and I) have recently also been shown to impact the troposphere, notably by reducing the mixing ratios of O3 and OH. Their potential for impacting regional air-quality is less well understood. We explore the impact of halogens on regional pollutants (focussing on O3) with the European grid of the GEOS-Chem mode...

Replacing IFRS instead of Iranian accounting standard

Accounting standards, are rules governing how to do accounting work, and specify what information must be provided in financial reporting. The main objective of this study was to compare the stronger accounting standards against weaker accounting standards which in this study, we compare accounting standards of Iran and international standard in terms of Rents. The population of the research is...
