Rice straw and corn were selected as raw materials to prepare biocharby anoxic carbonization the biochar was loaded on surface with FeCl3, MnCl2 Fe(NO3)3 & KMnO4, respectively, then two types of six modified prepared. FT-IR, SEM, XRD used characterize analyze physical chemical properties biochar. The adsorption kinetics isothermal tests Cd2+ ions in aqueous solution carried out. results sho...

PURPOSE The removal of excessive melanin pigments that obscure ocular tissue morphology is important to address scientific questions and for differential diagnosis of ocular tumours based on histology. Thus, the goal of the present study was to establish an effective and fast melanin bleaching method for paraffin and frozen mouse and human ocular tissues. METHODS Paraffin-embedded and frozen ...

The nanostructure of Ce doped OMS-2 plays a very important role in its catalytic property. We demonstrate by density functional theory (DFT) calculations that the unique nanostructure of the Ce ion substituted OMS-2 with Mn vacancy in the framework is beneficial for the improvement of catalytic activity, while the nanostructure of the Ce ion substituted OMS-2 without defects are detrimental to ...

Murine polyomavirus (Py) and simian virus (SV40) encode homologous large T antigens (T Ags) and also have comparable sequence motifs in their core replication origins. While the ability of SV40 T Ag to produce specific distortions within the SV40 core replication origin (ori) in a nucleotide-dependent fashion has been well documented, little is known about related effects of Py T Ag on Py ori D...

The Golgi apparatus of most plant and animal cells occurs as a system of dictyosomes (4), often dispersed throughout a large portion of the cytoplasm. Each dictyosome consists of a stack of cisternae (usually 5 or 6) and associated vesicles. The central region of a typical cisterna is sacor platelike and about a/~ /z in diameter. Tubular proliferations extend from this central structure, unit i...
