Abstract: A firearm assembly includes an upper receiver housing a bolt carrier group that is translatable within the upper receiver, and a lower receiver including a first hinge portion defining a first hinge opening. A second hinge portion is pivotally connected to the first hinge portion, and a buffer assembly is attached to the second hinge portion. A carrier block is positioned within the first hinge portion and is configurable in a blocking configuration and an unblocking configuration. A lock is configurable in a latched position and an unlatched position, and the lock is in mechanical communication with the carrier block when the lock is in the latched position. The carrier block is positioned in the unblocking configuration when the lock is in the latched position, and the carrier block is positioned in the blocking configuration when the lock is in the second position.

Abstract: This invention relates to high drug load compositions of medium chain triglycerides (MCT), and to methods for treatment with such compositions at amounts effective to elevate ketone body concentrations so as to treat conditions associated with reduced neuronal metabolism, for example Alzheimer's disease.

Abstract: A firearm assembly includes an upper receiver housing a bolt carrier group that is translatable within the upper receiver, and a lower receiver including a first hinge portion defining a first hinge opening. A second hinge portion is pivotally connected to the first hinge portion, and a buffer assembly is attached to the second hinge portion. A carrier block is positioned within the first hinge portion and is configurable in a blocking configuration and an unblocking configuration. The second hinge portion is in mechanical communication with the carrier block when the second hinge portion is configured in a folded position. At least a portion of the carrier block is positioned within the first hinge opening when the carrier block is in the blocking configuration. The carrier block prevents translation of the bolt carrier group when the carrier blocking member is in the blocking configuration.

Abstract: Disclosed herein is an apparatus for facilitating enhancing operations of a computer numerical control (CNC) cutting machine, in accordance with some embodiments. Further, the CNC cutting machine comprises a support table, a gantry, a carriage, and a main cutting tool. Further, the gantry is configured to move vertically along a length of the support table and the carriage is configured to move horizontally on the gantry along a length of the gantry defining an operation area on the support table. Accordingly, the apparatus comprises an extension device. Further, the extension device comprises a first end and a second end. Further, the first end is attachable to a carriage housing of the carriage and a tool holder is comprised in the second end. Further, the extension device is configured to extend between two positions. Further, the tool holder is configured for removably holding an auxiliary cutting tool.

Abstract: The present invention provides methods and compositions for the delivery of a biologically active agent to a biological system. The compositions include the active agent and a lyotropic phase and release of the active agent to the biological system is modified by the lyotropic phase.

Abstract: The invention provides a compound containing a head group based on urea, glycerol or glycerate and a tail selected from the group consisting of a branched alkyl chain, a branched alkyloxy chain or an alkenyl chain. The compounds may be used as surfactants to form a lyotropic phase that is stable in excess polar solution.
