Abstract: Lubricating composition comprising (i) base oil and (ii) a Verkade base compound having the formula (1): wherein R1, R2 and R3 are each independently selected from hydrogen and saturated or unsaturated, straight chain or branched, C1-C22 alkyl groups. The lubricating composition of the present invention exhibits improved base number retention and oxidative stability, particularly in the presence of a biofuel such as fatty acid alkyl ester.

Abstract: A system for managing an agricultural resource comprising an input module arranged to receive inputs from a plurality of input sources; a central processor arranged in data communication with the input module to generate at least one long term forecast; the central processor further configured to receive inputs from selected input sources at a predetermined time to adjust a parameter of the at least one long term forecast to derive a short term forecast; and an output module arranged in data communication with the central processor to receive the long term forecast and/or the short term forecast for decision control; the output module arranged in data communication with at least one output device, is disclosed.

Abstract: A tracer-liner portion comprises an inner tube and an outer tube, each including at least one wall having an internal surface and an external surface, the walls of the inner tube and the outer tube being impermeable to fluid flow, the outer tube having an internal diameter which is larger than the outer diameter of the inner tube, the inner tube being arranged coaxially within the outer tube such that at least a portion of the external surface of the inner tube is covered by the outer tube; the internal diameter of the outer tube exceeds the outer diameter of the inner tube by an amount sufficient to form a space between the external surface of the inner tube and the internal surface of the outer tube, and a tracer material containing a tracer compound is present in the space.

Abstract: A Christmas tree and a method of completing a well in a standard wellhead. The tree is presented as separately deployable upper and lower portions with the master valves contained in the lower portion so that they are located below the wellhead housing to lower the height of the tree while increasing well safety and integrity. The upper master valve is bi-directionally sealing to allow for pressure testing, removing the requirement for tubing hanger plugs.

Abstract: A fuel door assembly for a motor vehicle is provided. The fuel door assembly includes a housing, a fuel door and a door seal. The fuel door is hingedly supported by the housing for rotation between an open position and a closed position. The door seal includes a proximal edge supported by the housing and a distal edge separated from the housing. The door seal has an arcuate shape extending from the proximal edge to the distal edge when the fuel door is in the open position.

Abstract: Techniques are described herein for automatically determining play states, intrinsic motivators, play types/patterns and a play personality of a user/subject. Play personalities develop from activation of play states, and vary individually and are expressed in a variety of play type/patterns. These states, personalities, patterns and associated intrinsic motivations may be automatically determined by computing devices based on that user/subject's information, behaviors and biometric data. The play personality may be additionally used as the means for identifying and integrating intrinsic motivators into player-centric design which can alter and personalize user/subject/player engagement, experience and outcomes.

Abstract: Techniques are described herein for automatically determining a play personality of a user. Play personalities develop from play type and play patterns, which may be automatically determined by computing devices based on that user/subject's information and actions. Furthermore, in a gaming environment, the play personality of the user/subject may be represented by an avatar, doppelganger, narrative, graphic or iconic depiction. The play personality may be determined based on the avatar or doppelganger's actions, which may include but are not limited to how they respond to questions posed by non-playing characters and/or the avatars or doppelgangers of other users. Once determined, the play personality may be used as a basis for identifying and integrating intrinsic motivators and integrating user-centric design which can alter some aspect of the game environment, such as the appearance of the avatar, or the nature of a quest, or means for identifying or exploring solutions in gamification.
