In this study, the potential use of halophyte grasses, Aleuropus littoralis and A. lagopoides, on soil desalinization and lowering soil salinity was investigated under glasshouse conditions. The seeds of two species were collected from Rodasht area in Isfahan and grown with four salinity treatments obtained from different types of collected soils and replicated three times. Electrical conductiv...

The purpose of this study is to clarify the chemical characterization of PM2.5 and PM10 in diesel exhaust particles (DEP). Sampling of PM2.5 and PM10 in DEP was carried out in November 1999 using an automobile exhaust testing system at the National Traffic Safety and Environment Laboratory, with a diesel truck (engine type: direct injection, displacement: 7,961 cc, carrying weight: 2,020 kg, eq...

The formation constants of the species formed in the systems H+ + cytidine 5-monophosphate (CMP)and H+ + cytidine 5-monophosphate + Tl (I) ion have been determined in aqueous solution in a widepH range of 1.5 to 10.5 at 25 °C and different ionic strengths ranging from 0.1 to 1.5 moldm-3NaClO4, NaNO3, and NaCl using potentiometric-spectrophotometric technique. The composition ofthe complexes was...

Processing of multimeric precursor tRNAs from Bacillus subtilis by the catalytic RNA component of RNase P was studied in vitro. Previous studies on processing by either Escherichia coli or B. subtilis RNase P-RNA utilized monomeric or dimeric substrates. In the experiments described here, a multimeric precursor tRNA containing six complete tRNA sequences and the partial sequence of a seventh we...

Ionic liquids exhibit a remarkably diverse interfacial chemistry. Recent theoretical and experimental results show that conventional double layers do not form on metal electrodes in ionic liquid systems, rather a multilayer morphology is present. The number of layers and the strength of adsorption are strongly dependent on ionic liquid chemical species, solutes and applied electrode potential. ...

Mechanisms of uptake of rare earth elements (REEs) were investigated, particularly those by REE accumulator species (autumn fern). Rare earth elements are practically insoluble under natural conditions, suggesting some unknown mechanism in REE accumulator species. In the present investigation, two notable phenomena were observed. (I) Concerning the ionic-radius dependence of REE uptake by leave...
