Processo eletrolítico em efluente de refinaria de petróleo utilizando eletrodos de ti/tiruo2 e/ou fe/tiruo2

Consiste de uma modalidade de tratamento de efluentes líquidos de refinaria de petróleo que pode ser usado isoladamente ou preferencialmente e mais eficazmente de forma complementar e anterior ao tratamento biológico que utiliza-se de eletrodos óxidos do Ti/TiRuO~ 2~ E/OU Fe/TiRuO~ 2~ os quais atuam no processo de conversão ou combustão eletroquímica de substâncias persistentes ou tóxicas presentes nestes entes, particularmente fenol, amónia, nitrito e cloreto em outras substâncias mais degradáveis e menos tóxicas...

Pulsing With Low Concentration Gibberellin Plus Benzyladenine or Commercial Floral Preservatives Affect Postharvest Longevity, Quality, and Leaf Chlorosis of Cut Lilies and Gladioli

Effects of pulsing with different concentrations of gibberellin plus benzyladenine (GA(4+7) + BA), a proprietary mixture of GA(4+7) plus BA in a commercial floral preservative (GA(4+7) + BA + preservative), or a propriety mixture of sugar plus acidifier developed for bulbous flowers (floral bulb preservative) were studied on postharvest performance and quality of cut lily (Lilium hybrids) and gladiolus ( Gladiolus hybrids) flowers. Pulsing of cut stems of lily with GA(4+7) + BA at 5 or 2 mL.L-1 GA(4+7) + BA + preservative for 20 hours at 3 +/- 1 degrees C extended the vase life and controlled leaf chlorosis of 'Cobra'oriental lily and 'Cappuccino'and Pot Corn'asiatic lily. Cut 'Orange Art'asiatic lily performed best when pulsed with GA(4+7) + BA at 10 mg.L-1. For cut gladiolus, pulsing with GA(4+7) + BA at 10 mg.L-1 extended the vase life of 'Alice', 'Mammoth', and 'Passion', while 'Scarlet'had the longest vase life when pulsed with 5 mg.L-1 GA(4+7) + BA. GA(4+7) + BA + preservative also extended the vase life and controlled leaf chlorosis, but the floral bulb preservative had no effect on vase life extension or preventing leaf chlorosis of lilies. Gladiolus cultivars had no or minor leaf chlorosis during vase period. Overall, overnight pulsing with GA(4+7) + BA + or GA(4+7) + BA + preservative extended the vase life and prevented leaf chlorosis

Bioactivity of pyridine-2-thiolato-1-oxide metal complexes: Bi(III), Fe(III) and Ga(III) complexes as potent anti-Mycobacterium tuberculosis prospective agents

In the search for new therapeutic tools against tuberculosis and to further address the therapeutic potential of pyridine-2-thiol 1-oxide (Hmpo) metal complexes, two new octahedral [M(III)(mpo)3] complexes, with M = Ga or Bi, were synthesized and characterized in the solid state and in solution. Attempts to crystallize [Ga(III)(mpo)3] in CH2Cl2 led to single crystals of the reaction product [GaCl(mpo)2], where the gallium(III) ion is in a square basis pyramidal environment, trans-coordinated at the basis to two pyridine-2-thiolato 1-oxide anions acting as bidentate ligands through their oxygen and sulfur atoms. The biological activity of the new [M(III)(mpo)3] complexes together with that of the previously reported Fe(III) analogous compound and the pyridine-2-thiol 1-oxide sodium salt (Na mpo) was evaluated on Mycobacterium tuberculosis. The compounds showed excellent activity, both in the standard strain H37Rv ATCC 27294 (pan-susceptible) and in five clinical isolates that are resistant to the standard first-line anti-tuberculosis drugs isoniazid and rifampicin. These pyridine-2-thiol 1-oxide derivatives are promising compounds for the treatment of resistant tuberculosis.
