the current study is focused on determination of the accumulation rate of cadmium (cd) and lead (pb) in the liver and muscle tissues of the caspian kutum fish. specimens were collected randomly from twelve stations in mazandaran province, the caspian sea basin, between october 2009 and march 2010. fork length, weight and length-weight relationship of samples were measured. one-way analysis of v...
فرض کنیم g گروهی متناهی,irr(g)مجموعه تمام سرشتهای تحویل ناپذیر (مختلط)g و cd(g)مجموعه درجات آنها باشد.موضوع اصلی این پایان نامه مطالعه گروههایی مانند g است که برای آنها cd(g)یا cd(g-1) مجموعهای از اعداد صحیح مثبت متوالی باشند.جنین گروههایی ,ccd-گروه نام دارد.بخصوص نشان می دهیم که اگر cd(g)={1,2,..k}آنگاه k<4 و g حلپذیر است یا k=6 و g زیرگروهی جون h داردکه(2,5)h?sl و g=hz(g.)
in this study chitosan hydrogel beads with porosity ~ 0.86 and diameter ~ 20.07 mm were prepared from 85 % deacetylated chitosan for removal of cd2+ ions from aqueous solutions. chitosan powder was dissolved into dilute acetic acid as solvent and formed into spherical beads using a phase inversion technique. the effect of temperature, initial concentration of cd2+ ions, and the period of agita...
