  • Publication number: 20220228327
    Abstract: The present invention is an artificial grass block that can accommodate to the different sized cells of the similar grass pavement stones produced by different companies. The artificial grass block can bear an up to 10% size difference of the cells. The artificial grass block can carry out this function by its elastic, flexible positioning-fixing unit, which positions and fixes the artificial grass block inside the cell of a certain size range. The positioning-fixing unit is longer than the cell before insertion and deforms during insertion. This deformed positioning-fixing unit creates a tension that appropriately positions and firmly fixes the artificial grass block within the cell. EOIC 5/20 Pavings made of prefabricated single units; made of units of plastics; EOIC 9/225 Pavings specially adapted for allowing vegetation; EOIC 11/225 Paving specially adapted for through-the-surfacing drainage, e.g.

  • Patent number: 8367394
    Abstract: The present invention relates to a novel selective synthesis of 9?-hydroxy-steroid derivatives of the general formula (I) (I)—wherein the meaning of -A-A?- is —CH2—CH2— or —CH?CH— group—by the bioconversion of compounds of the general formula (II) (II) wherein the meaning of -A-A?- is —CH2—CH2— or —CH?CH— group—by using Nocardia farcinica bacterium strain, deposition number of which is NCAIM (P)—B 001342, as hydroxylating microorganism in the bioconversion.
