Abstract: Example furnaces and methods related thereto include a burner box including at least one burner configured to combust a fuel/air mixture. In addition, the furnace includes a first blower including an inlet nozzle having an air inlet and fuel inlet. The inlet nozzle is configured such that operation of the first blower is to pull air and fuel into the inlet nozzle to produce the fuel/air mixture at a fuel/air ratio that is configured to produce flue products having less than 14 Nano-grams per Joule of nitrogen oxides when combusted. Operation of the first blower is configured to push the fuel/air mixture into the burner box. Further, the furnace includes a heat exchanger assembly fluidly coupled to the burner box through a vestibule, and a second blower configured to pull the flue products through the heat exchanger assembly.

Abstract: Disclosed herein are compounds having Formula I, which are non-natural L-adenosine analogs. Also disclosed are their methods of making. Still further, disclosed are the uses of the disclosed compounds to treat cardiovascular disease, ischemia related injuries; and neurodegenerative diseases. The compounds disclosed herein have the formula: wherein R1 and R2 are, independently, H, branched or straight-chain, substituted or unsubstituted alkyl, alkenyl, alkynyl, or aryl; R3 is branched or straight-chain, substituted or unsubstituted alkyl, hydroxy-alkyl, or —C(?O)NR6R7; and R4 and R5 are, independently, H, hydroxy, halogen, and NR8R9, wherein R6, R7, R8, and R9 are, independently, H, branched or straight-chain, substituted or unsubstituted alkyl, alkenyl, alkynyl, or aryl.

Abstract: A game of skill includes a lighted circular target intended to simulate the sun. A joystick is used to manipulate a crane mechanism and buttons are provided to allow the crane mechanism to be lowered and raised with an included magnet being used to allow lifting and dropping of magnetically attractive disks. The object of the game is to lift each disk, in turn, and to manipulate the joystick to cause disks to be dropped onto the simulated solar target surface to cover as high a percentage of the solar target surface as possible. An indicator is provided to indicate how much of the solar target surface has been covered, and a timer display displays the elapsed time.

Abstract: The disclosure describes an aqueous ceramic slurry having from about 70-weight percent to about 85 weight-percent of a fused yttria-zirconia material. The weight percent of zirconia in the fused yttria-zirconia preferably varies from about 1.0 weight percent to about 10.0 weight percent. Fused slurries may comprise, in addition to fused yttria-zirconia, an inorganic binder (preferably silica), an organic binder (preferably a latex binder), a surfactant (preferably a sodium dioctyl sulfosuccinate), an antifoaming agent (preferably a water-dilutable active silicone defoamer) and titanium dioxide. The slurries of the present invention are used to form ceramic mold facecoatings for casting reactive materials. These slurries are less sensitive to pH fluctuations than are slurries made from 100 percent yttria (yttria slurries). Moreover, slurries as described in the disclosure do not gel prematurely, and exhibit substantially the same formation of oxygen-enriched titanium (alpha case) than do yttria slurries.
