Abstract: Disclosed is a hydrodynamic effect device (100) for a flotation body (10) of an inflatable water sports device (1). The hydrodynamic effect device (100) comprises an attachment portion (102) for attaching the hydrodynamic effect device (100) on the rear end (18) of the flotation body (10), for example on the bottom (12) of the flotation body (10). The hydrodynamic effect device (100) comprises at least one separating edge portion (104) which is movable relative to the attachment portion (102) and which, when the flotation body (10) is moved on the water surface, is in contact with water in order to effect an improved and flexible flow separation at least on the rear end (18) of the flotation body (10).

Abstract: A torsion spring assembly according to the invention includes a torsion spring having a cylindrical spring body of wound spring wire and with a plurality of torsion spring windings, and having first and second torsion spring ends for taking up forces in a direction of rotation, and a damping spring abutting the torsion spring on the inner side and having a cylindrical spring body of wound spring wire and with a plurality of damping spring windings, and having first and second damping spring wire ends, wherein the damping spring windings have their outer sides extending partially into the space formed between two respectively adjacent torsion spring windings and abutting in particular rounded, round or beveled inner abutment areas of respectively adjacent torsion spring windings with substantially radially outwardly directed bias.

Abstract: The invention relates to transgenic plants and plant cells comprising a reduced expression of invertase inhibitors. The modification of the expression of the invertase inhibitors is achieved by introducing a cDNA sequence in an antisense orientation with respect to a promoter. The expression of the antisense DNA sequence is under the regulation of either the CaMV35S promoter or a tissue specific promoter.

Abstract: The present invention relates to a process and means for producing an improved sugar beet, in particular a sugar beet which exhibits an increased content of sucrose, a reduced rate of sucrose breakdown during storage and an improved growth. The invention also relates to the use of at least two gene constructs for generating such a plant and to nucleotide sequences which are employed in this connection.

Abstract: The present invention relates to a nucleic acid molecule encoding a vacuolar invertase and its use for modifying the plant saccharose metabolism, in particular in the vacuole of the cell of a plant storage organ. The present invention also relates to a fragment of the nucleic acid molecule, a vector containing the nucleic acid molecule or a fragment thereof, as well as a host cell, in particular a plant cell that contains the nucleic acid molecule or a fragment thereof. The present invention also comprises a transgenic plant, methods for producing a transgenic plant, as well as methods for modifying the saccharose metabolism of a plant, in particular of a plant part.

Abstract: To express selection genes and resistance genes, it would be desirable to have available plant constitutive promoters which has a strong uniform constitutive activity in as many plant tissues or cell types as possible and which, moreover, show an even stronger activity, or are not repressed, under stress conditions. The invention provides DNA constructs which encompass a plant V-ATPase promoter which is operatively linked with a heterologous gene. The invention furthermore relates to the use of these constructs in the form of expression cassettes, recombinant vectors and in transgenic plants, plant cells or protoplasts. In particular the invention relates to the promoter of the Beta vulgaris V-ATPase subunit c isoform 2.
