    摘要： The present invention describes a synthetic non-viral vector composition for gene therapy and the use of such compositions for in vitro, ex vivo and/or in vivo transfer of genetic material. The invention proposes a pharmaceutical composition containing 1) a non-cationic amphiphilic molecule or macromolecule and its use for delivery of nucleic acids or 2) a cationic amphiphilic molecule or macromolecule that transforms from a cationic entity to an anionic, neutral, or zwitterionic entity by a chemical, photochemical, or biological reaction and its use for delivery of nucleic acids. Moreover this invention describes the use of these non-viral vector compositions in conjunction with a surface to mediate the delivery of nucleic acids. An additional embodiment is the formation of a hydrogel with these compositions and the use of this hydrogel for the delivery of genetic material. A further embodiment of this invention is the use of a change in ionic strength for the delivery of genetic material.

    摘要： With this circuit, a current may be caused to flow through a contact (K) controlling the voltage supply of an electronic control circuit (24), of sufficient intensity for the reliability of the contact to be good, without the current flowing in the control circuit (24) being too high and this independently of the supply voltage (terminals E, 44) applied to the supply terminals of the user circuit (U). For this, the control circuit (24) is fed with power when the contact (K) is closed, through said contact (K), a first diode (31) and a resistor (32) connected in series, whereas a piloting circuit (11), which is an integrated time delay or memory circuit associated with said user circuit (U), is then supplied through said contact (K) and a second diode (26). When contact (K) is open, said piloting circuit (11) is fed through a third diode (29) and a Zener diode (30), the second diode (26) then preventing the control circuit (24) from being supplied with power.

    摘要： A process for the in-ladle treatment of liquid steels by injecting gas through the ladle bottom. The process comprises injecting at least one inert gas from locations which are distributed over the ladle bottom in such a way as to form at the surface of the liquid steel an annular swelling, the outside edge of which is close to the inside edge of the lining of the wall of the ladle. An oxidizing gas may be mixed with the inert gas for decarburization. The process is applied in particular to the treatment of carbon steels.
