Abstract: An adapter (112) for connecting a wiper blade to a drive arm, the adapter comprising two substantially parallel walls (28) connected together by at least one connecting element (30), said walls comprising first inner side faces (28a) between which said at least one connecting element extends, and outer side faces (28b) comprising protruding sliding guide patterns (132), characterised in that said patterns are divided into lines and columns.

Abstract: A rollover prevention system prevents a construction machine from rolling over. The rollover prevention system comprises a first angle detection unit (12) disposed adjacent to a turning joint (11) to detect a swing angle of the upper frame (5), a second angle detection unit (13) disposed on the upper frame to detect an angular movement of the upper frame, safety valves (40) disposed on flow passages (25, 32) communicating with hydraulic cylinders for a work attachment (10) and a swing motor (26) to control flows of working oil supplied to the hydraulic cylinders by opening and closing the flow passages in response to external signals, and an electronic controller (14) electrically connected to the first angle detection unit, the second angle detection unit, and the safety valves. The electronic controller comprises a barycenter calculating section (14a), a safety range determining section (14b), and a signal outputting section (14c). A rollover prevention method for a construction machine is also provided.

Abstract: A Stevia rebaudiana plant is characterized by Rebaudioside A (RA) content of 6-20% dry weight and total steviol glycosides content of 15-28% dry weight in the leaf. The plant is developed using selective breeding technologies and identified by RAPD gene analysis.

Abstract: A new stevia variety is characterized by remarkably high levels of Rebaudioside C (RC), and developed by the use of non-GMO selective breeding technologies and wherein such variety is uniquely identified by RAPD gene analysis, and comprises from about 3-8% by weight RC in the leaf (leaf content) and from about 10-13% total steviol glycosides content (TSG) in in leaf (leaf content), both of which are exceptionally high.

Abstract: A new stevia variety is characterized by remarkably high levels of Rebaudioside A (RA), and developed by the use of non-GMO selective breeding technologies and wherein such variety is uniquely identified by RAPD gene analysis, and comprises at least about 7-20% by weight RA in the leaf (leaf content), and comprises about 15-28% by weight total steviol glycosides in the leaf.

Abstract: A method for breeding Stevia rebaudiana with a high content of RA comprises selecting the plants in the perfect stage with a high RA content as parents and hybridizing them to produce F1 generation seeds; stabilizing the traits of the F1 generation in the imperfect stage; producing F2 generation seeds by a backcross method and optionally producing F3 generation seeds by a further backcross method.

Abstract: The present invention relates to a portable blower-vacuum device which comprises a motor (3) operated by a switch (7) and located in a main body (2) and a fan (4) drivable by the motor. A vacuum nozzle (11) and a blower nozzle (12) are associated with the main body and the vacuum nozzle comprises a main portion (14a) extending in a direction of an axis (Z1) of the main portion and a terminal portion (14b) with an axis (Z2) angularly disposed with respect to the axis (Z1) of the main portion.

Abstract: A storage box for storing power tool bits comprises a container, a bit holder and a control device. The container defines a compartment in which is received the bit holder along a common rotary axis. The bit holder comprises a plurality of outwardly radial pockets for receiving bits. The control device selectively disengages from the bit holder so that the bit holder is rotational about the common axis to move the bits rotationally in and out of the compartment.
