The performance of different activated carbons for the removal of nonionic surfactants from metallurgic wastewater was assessed through lab scale experiments. Two different matrices were used: a simple one, obtained by dissolving different amounts of a single nonionic surfactant (Triton X100) in distilled water, and a complex matrix, prepared as above but using surfactants-free wastewater from ...

The widespread use of titanium dioxide nanoparticles (TiO2NPs) in consumer products has led to an increase of their concentrations in the environment. For reliable determination of their total concentrations, the microwave assisted digestion procedure for the decomposition of nanoscale anatase and rutile was optimized and Ti concentrations were determined by inductively coupled plasma mass spec...

The glycoprotein profile of Bernard-Soulier platelets was examined by labeling washed platelets with periodate 3H-sodium borohydride, a procedure that labels greater than 30 glycoproteins on the membrane surface of normal platelets. Three Bernard-Soulier patients were studied; two were siblings and the third was unrelated. The platelet protein and glycoprotein profiles were evaluated under nonr...

A gene encoding a special thermophilic multifunctional amylase OPMA-N was cloned from Bacillus sp. ZW2531-1. OPMA-N has an additional 124-residue N-terminal domain compared with typical amylases and forms a relatively independent domain with a β-pleated sheet and random coil structure. Here we reported an unusual substrate and product specificities of OPMA-N and the impact of the additional N-t...

The glucose Enzyme II transporter complex of the Escherichia coli phosphotransferase system (PTS) exists in at least two physically distinct forms: a membrane-integrated dimeric form, and a cytoplasmic monomeric form, but little is known about the physical states of these enzyme forms. Six approaches were used to evaluate protein-protein and protein-lipid interactions in this system. Fluorescen...

In the present research work, evaluation of a non-ionic gemini surfactant derived from palm oil named bis(2-((2-palmitoamidoethyl) amino) ethyl) 1H-imidazole-4,5-dicarboxylate as an ecological corrosion inhibitor X100 steel immersed in NaCl solution at 3.5% saturated with carbon dioxide (CO 2 ) was analyzed. The electrochemical tests performed by Polarization Curves (PC) and Electrochemical Imp...

Physiol. 188(2): 399-402. rg57.-When postheparin plasma was incubated with a coconut oil substrate, a decrease in optical density and an increase in unesterified fatty acids occurred. The increase in unesteri...
