the modified surface of typha latifolia l. root (mstl), as an alternative economical adsorbent, wasused for the removal of ni (ii) and cd(ii) ions from aqueous solutions. the effect of initial ph, initialconcentration of metal ion, and contact time was investigated in a batch system at room temperature.the kinetics data could be fitted well by pseudo-second-order model with correlation coeffici...

objective: the aim of this study was to compare the qeeg of adolescents affected by bipolar ii disorder with age and gender matched healthy controls, and to extract the characteristics of the alpha frequency band to better understand this disorder. methods: twenty one adolescents affected by acute episodes of bipolar ii disorder (bmd ii), both hypomanic and depressive episodes, were selected vi...

purpose : to compare results of different methods for true corneal power determination and intraocular lens (iol) power calculation formulas in 10 eyes of 7 patients with previous radial keratotomy (rk) with or without astigmatic keratotomy methods : in this case series study, we determined the corneal power of 10 eyes of 7 patients who had undergone rk with or without astigmatic keratotomy wit...

two newly-created water-soluble complexes of palladium(ii)/platinum(ii)-dithiocarbamate, [pd/pt(phen)(pyr-dtc)]no3 (phen = 1,10-phenanthroline and pyr-dtc = pyrrolidinedithiocarbamate) were synthesized. also, their chemical characteristics are reported in the current research paper. in these complexes, the dithiocarbamato ligand coordinates to pt(ii) or pd(ii) center with two sulfur atoms as bi...

in the current investigation a novel nano hybrid adsorbent mcm-41/n-(3-trimethoxysilyl)-propyl)diethylenetriamine (mcm-41/tmspdeta) was prepared and was characterized using dls (dynamic light scattering), fourier transform infrared (ftir), x-ray diffraction (xrd), brunauer–emmett–teller (bet) analytical techniques and transmission electron microscopy (tem). the synthesized mcm-41/tmspdeta adsor...
