  • A novel flotation column for oily water cleanup

    Aug 09, 1999· Abstract. A novel multi-stage loop-flowflotation column(MSTLFLO®) was developed for fine particle separations. The unique design feature of theMSTLFLO columnis the use of draft-tubes to achieve multi-stage configuration and minimize back-mixing/entrainment in flotation. As a potential application, the column was studied for its performance in separating emulsified oil from water.

  • The HIV transactivator TAT binds to the CDK activating

    Oct 15, 1997· The human immunodeficiency virus (HIV) encodes a highly conserved transcriptional transactivator Tat, that is expressed early in the viral life cycle and is essential for viral replication and progression to disease (Cullen 1993; Jones and Peterlin 1994).Tat binds to the transactivation response (TAR) RNA stem–loop located from positions +1 to +60 in the viral 5′ long terminal repeat (LTR).

  • Analogues and derivatives of Oncrasin 1,a NovelInhibitor

    Apr 28, 2011· To optimize the antitumor activity of oncrasin-1, a small molecule RNA polymerase II inhibitor, we evaluated 69 oncrasin-1 analogues for their cytotoxic activity against normal human epithelial cells and K-Ras mutant tumor cells. About 40 of those compounds were as potent as or more potent than oncrasin-1 in tumor cells and had minimal cytotoxic effect on normal cells.

  • Nanobubbles at the Interface between Water anda

    A very thin layer (5−80 nm) of gas phase, consisting of discrete bubbles with only about 40 000 molecules, is quite stable at the interface between a hydrophobic solid and water.
