dans le monde où l’homme est l’élément le plus important de la vie, la formation de nouvelles générations a une importance particulière. en rédigeant emile, jean jacques rousseau, exerce une influence extraordinaire sur la vie humaine et mène à réfléchir sur la question de l’éducation en tant qu’un art. ce penseur du xviiie siècle, grâce à son élève imaginaire, emile, présente son idéal pédagog...
A new tris-(2-aminoethyl)amine (TREN) capped tripodal Schiff base ligand has been developed by mimicking structural features of a natural siderophore, Bacillibactin, by substituting the catechol units with salicylaldehyde and employing amino acid as spacer. Synthesis of the ligand N-[2-[bis[2-[[2-[(2-hydroxyphenyl)methylamino]acetyl] amino]ethyl]amino]ethyl]-2-[(2-hydroxyphenyl)methylamino]...
The constitutive relationships presented for concrete modeling are often associated with unknown material constants. These constants are in fact the connectors of mathematical models to experimental results. Experimental determination of these constants is always associated with some difficulties. Their values are usually determined through trial and error procedure, with regard to experimental...
Experiments were carried out to study the rate of PCDD/F formation from carbon on fly ash. The formation follows first order behaviour during the first part of the experiment. With longer reaction times, degradation reactions become more important. Rate constants found were in between 0.01-0.04 min -1.
The formation and structure of inclusion complexes of αand β-cyclodextrins with 2-chlorophenol (2CP), 3-chlorophenol (3CP), 4-chlorophenol (4CP), 2,4-dichlorophenol (24DCP), 2,6-dichlorophenol (26DCP) and 3,4-dichlorophenol (34DCP) have been studied by UV-VIS and 1H NMR spectroscopy. Both cyclodextrins were found to form 1 : 1 inclusion complexes. Binding constants estimated from titration stud...
The formation and liquid-liquid extraction of ion-association complexes between gallium(III)-4-(2-pyridylazo)resorcinol (PAR) anionic chelates and cations of four ditetrazolium chlorides (DT2+) were studied: Neotetrazolium chloride (NTC), Blue Tetrazolium chloride (BTC), Nitro Blue Tetrazolium chloride (NBT) and Tetranitro Blue Tetrazolium chloride (TNBT). The optimum extraction-spectrophotomet...
