  • Publication number: 20110023352
    Abstract: Provided herein are blends oils or fatty acids comprising more than 50% medium chain fatty acids, or the fatty acid alkyl esters thereof, and having low melting points. Such blends are useful as a fuel or as a starting material for the production of, for example, a biodiesel. Also provided genetically altered or modified plants, modified such that the amount of medium chain fatty acids generated by the plant are increased. Further provided is a method of predicting the melting point of a blend of fatty acid methyl esters and the use of such a method for identifying blends suitable for use as, for example, a biodiesel.

  • Publication number: 20100207460
    Abstract: An apparatus and method for substantially reducing the electrical energy consumption of a.c. induction motor-driven appliances by connecting a database predetermined capacitance in parallel with the motor-driven appliances and connecting a database predetermined inductance in series with the a.c. induction motor-driven appliances to effect the optimal power factor correction and optimal inrush current limiting of such motor-driven appliances thereby conserving electrical energy and reducing electrical energy costs. The databases of the present invention which specify the optimal power factor correction capacitance value and an optimal inductance value for specific a.c. induction motor-driven appliances eliminates the need for preliminary power factor and inrush current related electrical measurements and making the mass production and sale of the present invention practical.

  • Publication number: 20090298150
    Abstract: Provided herein compositions and methods for producing isoprenoids, including squalene. In certain aspects and embodiments provided are genetically altered yeast and uses therefore. In some aspects and embodiments, the genetically altered yeast produce isoprenoids, preferably squalene. The genetically altered yeast may have alterations in the expression or activity of enzymes involved in squalene production. for example, acetyl-CoA carboxylase (or “ACCase”), HMG-CoA reductase, squalene epoxidase, and squalene synthase. One or more genes of a genetically altered yeast may be modified by gene repair oligonucleobases. Also are provided methods of producing squalene using a genetically altered yeast. The invention also provides squalene produced by genetically altered yeast.

  • Publication number: 20080256668
    Abstract: The present invention relates to the production of a non-transgenic plant resistant or tolerant to a herbicide of the phosphoniorethylglycine family, e.g., glyphosate. The present invention also relates to the use of a recombinagenic oligonucleobase to make a desired mutation in the chromosomal or episomal sequences of a plant in the gene encoding for 5-enol pyruvylshikimate-3-phosphate synthase (EPSPS). The mutated protein, which substantially maintains the catalytic activity of the wild-type protein, allows for increased resistance or tolerance of the plant to a herbicide of the phophonomethylglycine family, and allows for the substantially normal growth or development of the plant, its organs, tissues or cells as compared to the wild-type plant irrespective of the presence or absence of the herbicide.

  • Publication number: 20070240230
    Abstract: Systems, methods and media for authenticating a user based on user-browser interaction are disclosed. Embodiments of a method may include, during an e-commerce session with a user, receiving a request for an action from the user and determining whether the requested action requires additional authentication. Embodiments may also include requesting analysis of user-browser interaction for the session, receiving a pattern matching score for the session, and performing an action based on the pattern matching score and the requested action. The pattern matching score may provide an indication of a comparison between the user's interaction with a browser during the session and a user-browser interaction profile for the user. The performed action may include completing an e-commerce transaction, accessing or modifying information, changing a password, requesting additional information, denying the requested action, or other action.

  • Publication number: 20070239604
    Abstract: Systems, methods and media for detecting fraudulent behavior during an Internet commerce session are disclosed. Embodiments of a method may include establishing an e-commerce session with a user and requesting fraud detection analysis of user-browser interaction during the e-commerce session. Embodiments may also include receiving fraud detection results for the e-commerce session, where the fraud detection results may provide an indication of a comparison between the user's interaction with a browser during the e-commerce session and known fraudulent behavior. Embodiments may also include performing an action based on the fraud detection results. Determining the fraud detection results may include determining user-browser interaction data associated with the session and comparing the user-browser interaction data to known fraudulent human or automated program behavior.

  • Publication number: 20070198645
    Abstract: A computer implemented method, data processing system, and computer program product for providing an in-context response to an instant message. One or more instant messaging chat conversations are displayed to a user. When a determination is made that the user has selected a turn in the chat conversation, a response input area is provided to the user, wherein the response input area is used to receive a response from the user to the selected turn. A link is created between the response and the selected turn. The response is sent to one or more participants in the chat conversation. At any point, the response input area may be minimized to a visual response indicator, wherein the visual response indicator is placed in proximity to the selected turn to indicate that the selected turn has an associated response. When a chat participant selects the visual response indicator, the linked response is displayed to the participant.

  • Publication number: 20070171854
    Abstract: A system and method for notifying emergency responders, family, and other contact parties of an urgent vehicle condition such as a breakdown or crash, by using a short-range wireless communicator mounted on the vehicle to employ a peer-to-peer communications capability to find and co-opt a nearby long-range communication device, such as a Bluetooth enabled phone, which is not mounted on the vehicle, such as a passer's-by telephone. The invention obtains authorization from the co-opted device to use it as a forwarding proxy, and transmits a notification message to one or more parties, such as emergency dispatchers, family members, etc., via the short-range link to the co-opted device, which then transmits the message to the recipient via the long-range network, such as via a telephone network.
