Abstract: A method of modifying ethylene biosynthesis in a plant comprises inserting into the genome of the said plant a DNA sequence such as SEQ-ID-NO-1 (encoding 1-aminocyclopropane-1-carboxylic acid synthase (ACS)) and/or sequence SEQ-ID-NO-2 (encoding an ethylene-forming enzyme (EFE)) which modifies the activity of at least one of ACS or EFE. The method may be used to modify fruit ripening characteristics, especially in bananas.

Abstract: The present invention provides for employing SQL to introduce blockchain technologies into a relational database, and thereby leverage the inherent tamper-resistant properties of blockchain, without the need to completely rewrite existing or legacy relational database software. The invention creates a relational database inside of a blockchain and uses a conventional SQL interface for standard database operations. This reduces the burden of introducing blockchain technologies, while providing the benefits of the intrinsic security and verification features of blockchain technology. The invention provides a rich historical record of every transaction thereby greatly reducing, if not eliminating, the relational database's susceptibility to tampering. This allows for temporal queries on arbitrary records within the database and the generation of reports and audits for any point in the history of the database.

Abstract: An aspirator for creating vacuum is disclosed that includes a housing defining a fluid passageway with a first tapering portion and a second tapering portion. Each tapering portion has a larger internal opening and a smaller internal opening, the smaller openings facing one another. The aspirator includes a gate positioned between and in fluid communication with the first and second tapering portions, the gate having a first Venturi tube with a Venturi opening creating vacuum when fluid flows in a direction and a second Venturi tube with a Venturi opening that creates vacuum when fluid flows in the opposite direction. The Venturi openings are in fluid communication with a suction port, and the first and second Venturi tubes may provide different mass flow rates through the aspirator. An engine system having an aspirator with a gate having a first bore and a second bore and an actuator is also disclosed.

Abstract: Recirculation systems for engine intake air are disclosed having a turbocharger compressor with an inlet and an outlet, a recirculation pathway connecting fluid flow from the outlet of the turbocharger compressor to fluid flow into the inlet of the turbocharger compressor, and a recirculation valve assembly controlling fluid flow through the recirculation pathway. The recirculation valve assembly includes an actuator operating a valve coupled to an aspirator assembly that produces vacuum when the fluid flows through the recirculation pathway from the inlet to the outlet and when fluid flows through the recirculation pathway from the outlet to the inlet. Fluid flows through the recirculation pathway from the outlet to the inlet when the turbocharger generates boost. The vacuum generated by the aspirator assembly is in fluid communication with the actuator to move the valve between two or more positions.

Abstract: Noise attenuation units are disclosed that are connectable in a system as part of a fluid flow path. Such units include a housing defining an internal cavity and having a first port and a second port each connectable to a fluid flow path and in fluid communication with one another through the internal cavity, and a noise attenuating member seated in the internal cavity of the housing within the flow of the fluid communication between the first port and the second port. The noise attenuating member enables the fluid communication between the first port and the second port to flow through the noise attenuating member.
