the problem of removing pollutants from water is an important process and is becoming moreimportant with the increasing of industrial activities. one of the most important environmental problems iswater resources pollution by heavy metals. bioabsorbtion is affordable adsorbents for the removal of heavymetals from aqueous solutions. this study explores the adsorption potential of cr (vi), cd (ii...

Four species of Laboulbeniales collected from Java Island, Indonesia between August and September in 2006 are described. These species, which belong to the genus Coreomyces and were found on the family Corixidae of the order Hemiptera, were as follows; Coreomycus corixae Thaxter, Coreomyces micronectae Thaxter and Coreomyces orientalis Thaxter, which were found on Micronecta sedula Horvath, and...

Acridocarpus orientalis is an important medicinal plant for some of the locals of Arabian region. Very little is known about its phytochemical constituents. In the present study, we aimed to isolate bioactive chemicals from the crude methanolic extract of the aerial parts of A. orientalis. The extraction and isolation resulted in the purification of two flavonoids: morin (1) and morin-3-O-β-D-g...

This study was executed to determine the plant species of herbaceous cover in a skid road subjected to soil compaction due to timber skidding in a beech (Fagus orientalis Lipsky.) stand. Our previous studies have shown that ground based timber skidding destroys the soils extremely, and degradations on ecosystem because of the timber skidding limit recovery and growth of plant cover on skid road...

A complement-fixing antigen specific for scrub typhus occurs in the body fluids and tissues of infected mice, white rats, and cotton rats. The specific serological substance is demonstrable only in those animals which develop a rapidly fatal disease after an incubation period of a few days. Such an experimental infection is induced in mice and rats by the intravenous injection of suspensions of...

A mutant gene, Pale, (/=") has been discovered in the discoglossid frog, Bombina orientalis. Breeding experiments indicate that the gene is recessive to the wild-type allele (P). Embryos, tadpoles and adults homozygous for the Pale gene are lighter in coloration than wild-type animals. Eggs produced by Pale females appear normally pigmented. Neural-retina defects were apparent in Pale tadpoles....

Lasinus orientalis Yin & Bekchiev, new species, is described from the eastern Chinese provinces of Zhejiang and Jiangxi, with major diagnostic features illustrated. The new species is compared with, and distinguished from related congeners.
