Abstract: Described herein are substrates coated with crystals having uniform crystalline morphology on the surface of the substrate. The coated substrates are useful in culturing and performing functional assays on cells such as, for example, resorption studies on bone cells. New methods for producing such coated substrates are also disclosed.

Abstract: A folding exercise rowing or sculling machine has left and right fold-down oar assemblies, each formed of an arm hinged to the side of the frame, and a pivot at the end of the arm on which the oar and oarlock are mounted. A cam plate at a lower end of the pivot pulls a cable that drives the sprocket wheel of a flywheel mounted to the rear or proximal of the frame. The oar assemblies fold to rearward, with the cam wheels fitting in a space between the flywheel and the frame. Multiplier pulley assemblies couple the power cable and elastic cords to a drive chain that is wound around the sprocket.

Abstract: Organic matter, i.e., biomass, fibrous plant matter, organic chemicals or organic waste, or other carbon-based matter is converted to synthesis fuel gas by reactive contact with superheated steam at a temperature of about 200 to 2000 degrees C., typically 500 to 1700 degrees. A reactor has a generally tubular envelope, a rotor within the envelope, and hot reaction spaces disposed annularly within the wall of the tubular envelope. The steam and biomass particles can be heated to the required temperatures by RF induction. The product gases include H2, CO, and CO2 in ratios controlled by a programmable controller. Control of temperature, biomass feed rate and water flow preselects the output synthesis gas mix. The synthesis gas may be processed into portable liquid fuels, or can be used directly in a fuel cell.

Abstract: The present invention relates to a method of making a soot particle and apparatus for making such soot particle. Preferably the method of making the soot particle is substantially free of the step of combusting a fuel and substantially free of the step of forming a plasma. Preferably, the apparatus is devoid of a heating element associated with both combustion and formation of a plasma. A preferred technique for at least one heating step for forming the doped soot particle is induction heating.

Abstract: An exercise canoe paddling machine has a frame, a pull cord that passes over an outer pulley and an inner pulley that are mounted on a pivotable pulley arm on the front of the machine, and thence under the machine to rotate a flywheel mounted beneath the frame. The cord is attached to an elongated canoe paddling handle. The pivoting pulley arm moves from side to side to follow movement of the paddling handle. The resistance that is produced during stroking of the handle is directed substantially parallel to the frame axis and to the same side thereof as the paddling handle.
