Abstract: Disclosed herein is a nanocomposite including a carbonaceous perimorph, the perimorph having a diameter of less than 1,000 ?m and comprising interconnected cells, each of a plurality of the cells comprising a carbonaceous cell wall possessing an average thickness of less than 100 nm or smaller and a morphology corresponding to a surface region of a, non-metallic template particle, the template particle having a diameter of less than 1,000 ?m, and an interior space bounded and enclosed by the cell wall.

Abstract: A system for a grading machine includes a lift cylinder sensor to measure a position or movement of a lift cylinder, which is coupled to a drawbar. The drawbar is coupled to a circle. The circle is coupled a blade carrier assembly, and the blade carrier assembly is coupled to a blade. The system also includes a drawbar sensor to measure a position or movement of the drawbar, a circle sensor to measure a position or movement of the circle, a blade carrier assembly sensor to measure a position or movement of the blade carrier assembly, and a blade sensor to measure a position or movement of the blade. A controller receives information from the lift cylinder sensor and one or more of the aforementioned sensors and determines whether one or more wear components is in need of inspection, repair, or replacement.

Abstract: Described here are devices and methods for strengthening the thenar muscles of the hand. Generally, a device comprises a base shaped to be held in the hand, a thumb rest having a hinge attached to the base such that one end of the thumb rest can be pivoted relative to the base, and an elastic member attached to the base and the thumb rest, which resists the pivoting motion of the thumb rest relative to the base. The user can place the device in his or her hand, and place his or her thumb on the thumb rest. When the user presses the thumb rest toward the base with his or her thumb, the elastic member supplies a force resisting the pressing motion, which exercises the thenar muscles.
