Abstract: Each of an osteochondral plug graft and a kit comprises a trapezoid shaped construct configured for osteochondral implanting. An osteochondral regeneration method comprises forming a recipient socket in a chondral area of an articular joint in need of repair; harvesting a trapezoid shaped graft from another chondral area; and implanting the trapezoid shaped graft into the recipient socket.

Abstract: Methods, systems, and processes are disclosed for determining emissions outputs. One method communicates with a communications network and acquires at least one of energy usage information associated with sources of emissions and emissions information associated with sources of emissions. The energy usage information and the emissions information is acquired as each occurs in real time. The method reports emissions outputs based upon the acquired real time information. Another method communicates with a communications network and acquires at least one of energy usage information associated with sources of emissions and emissions information associated with sources of emissions. This embodiment stores the acquired information as each occurs in real time. Emissions outputs are reported for the industrial process, the emissions outputs based upon the acquired real time information.

Abstract: An ultracapacitor comprises two solid, nonporous current collectors, two porous electrodes separating the collectors, a porous separator between the electrodes and an electrolyte occupying the pores in the electrodes and separator. At least one of the current collectors comprises a conductive metal substrate coated with a metal nitride, carbide or boride coating.

Abstract: A piston production method produces an internal combustion engine piston. The method comprises forging a billet from an initial billet comprising an aluminum alloy that comprises silicon, intermetallic particles, and injected hardening particles, the forging is conducted under at least one of super-plasticity and hot deformation conditions; and heat treating the forged billet. The forging comprises forging at a temperature in a range from about 0.8 Tmelt to about 0.98 Tmelt. The forging also comprises forging at a STRAIN rate in a range from about 5×10−2 s−1 to about 5×10−5 s−1. The piston being formed with a configuration that enables other as parts to be connected to the piston. The initial billet comprises at least one of: coarse grain silicon, intermetallic particles, and injected hardening particles having at least one of a lamellar, comprehensive shape, and fine grain silicon, intermetallic particles, and injected hardening particles being globular in shape.
