The structures of micelles of the surfactant polysorbate 80 (Tween 80) in 0-50% aqueous dimethyl sulfoxide (DMSO) solutions (pH 7.2, ionic strength 2.44 mM) were investigated by means of small-angle X-ray scattering. At DMSO concentrations of 0-20%, core-shell cylinder micelles formed, and at 30-50% DMSO, core-shell discus micelles formed, that is, changing the hydrophobicity of the DMSO solven...

This work examined teakwood and parawood in wood/poly(vinyl chloride) composite (WPVC) materials under UV-weathering seawater immersion. The mechanical properties as well anti-fungal anti-algal performance were considered. Teakwood (a rubberwood product) WPVC at ratios of 0:100, 20:80, 40:60, 50:50, 60:40, 80:20, 100:0 investigated. ageing periods 0 to 32 days immersion 90 studied. Aspergillus ...

scarce water resources is a worldwide problem, still for iran, a country predominated by an arid and semi-arid climate, water limitation is more severe than for many other areas of the world. a field experiment was conducted to investigate the impact of irrigation regimes on growth, grain yield and irrigation water use efficiency in maize (zea maize l.) in 2006 at the research farm, college of ...

yekta was created in 1981 from crossing between b5 ? m7 and an early maturing palistinian line, in oil seed crops research department of seed and plant improvement institute (spii) at karaj. the pure line of the cross was obtained after five years of selection with pedigree method. preliminary evaluation of the line along with other 31 selected lines was done in 1989 and yekta together with oth...

In order to examine the impact of pure and mixed planting on the production of grasses and also the biological control of weeds an experiment was conducted in the research farm of Alashtar city of Lorestan province between the years 1391 and 1392. This experiment within the design of complete random blocks (RCBD) with 6 protections which included 100:0 (rouph pea pure planting) 0:100 (pure plan...

In this paper, we work on extending a Chinese thesaurus with words distinctly used in various Chinese communities. The acquisition and classification of such region-specific lexical items is an important step toward the larger goal of constructing a Pan-Chinese lexical resource. In particular, we extend a previous study in three respects: (1) to improve automatic classification by removing dupl...
