Two recently sequenced genomes of the insect-pathogenic bacterium Photorhabdus and a large Serratia entomophila plasmid, pADAP, have phage-related loci containing putative toxin effector genes, designated the "Photorhabdus virulence cassettes" (PVCs). In S. entomophila, the single plasmid PVC confers antifeeding activity on larvae of a beetle. Here, we show that recombinant Escherichia coli exp...

Lead is quantitatively retained on 2-(5-bromo-2-pyridylazo)-5-diethylaminophenol (5-Br-PADAP)-ammonium tetraphenylborate with microcrystalline naphthalene or by a column method in the pH range 4.0-6.0 from a large volume of aqueous solutions of various samples with preconcentration factor of 60. After filtration, the solid mass consisting of the lead complex and naphthalene was dissolved wi...

Manganese is quantitatively retained on 2-(5-bromo-2-pyridylazo)-5-diethylaminophenol (5-Br-PADAP)-ammonium tetraphenylborate with microcrystalline naphthalene or by a column method in the pH range 7.5-10.5 from large volumes of aqueous solutions of various samples. After filtration, each solid mass consisting of the manganese complex and naphthalene was dissolved with 5 ml of dimethylformamide...

La migration japonaise au Bresil, qui debutât en 1908, peut etre concue comme la derniere grande vague migratoire transoceanique vers le Bresil contemporain.

In this work, a new extractant was prepared by immobilizing ligand 2-(5-bromo-2-pyridylazo)-5-diethylaminophenol, (5-Br-PADAP), on the activated carbon and applied to extraction of Pb(II) prior to determination by flame atomic absorption spectrometry. It was confirmed by FT- IR analysis. The metal ion was retained on the 0.05 g of the sorbent in the pH range 6-8, and then eluted with 5 mL of 0....
