Abstract: A snowmobile ice scratcher has a wire form in the shape of a hook secured to a track frame of the snowmobile. The wire form has a coil portion at the track frame and a downwardly extending leg portion that in an undeflected position has an elongate snow/ice spray generating portion configured as a flattened wire segment portion oriented downwardly, forwardly, and inwardly for generating snow/ice spray on hard packed snow and/or ice surfaces. An upwardly facing flat surface of the elongate snow/ice spray generating portion faces upwardly, inwardly, and forwardly and creates an ice/snow spray as the snowmobile is moving forward that is primarily directed inwardly to provide improved lubrication of the track assembly and improved deposition of ice/snow spray under the tunnel on a heat exchanger, thereby providing improved cooling of the snowmobile engine. The hook shape of the leg portion allows rearward operation of the snowmobile without damage to the ice scratcher.

Abstract: Disclosed is a vaporization apparatus including a ceramic core having a characteristic, such as porosity, that enables a vaporization substance to seep through the ceramic core, and a heating element configured to heat the ceramic core and generate vapor by atomizing the vaporization substance that seeps through the ceramic core. According to an embodiment of the disclosure, the characteristic of the ceramic core is designed to be non-uniform, with a view to control, at least to some extent, how the vaporization substance seeps through the ceramic core. In this manner, it may be possible to mitigate leakage of the vaporization substance out of the vaporization apparatus.

Abstract: A vaporization apparatus includes an atomizer to generate vapor from a vaporization substance and a channel, in fluid communication with the atomizer, to carry the vapor away from the atomizer. In an embodiment, the atomizer includes a ceramic core, and liquid is prevented from leaking through the channel One or more properties of the vaporization substance and/or one or more properties of the ceramic core may contribute to leakage prevention. In some embodiments, a liquid flow control structure in the channel controls flow of liquid within the channel.

Abstract: The invention provides a method of producing a population of human Schwann cells. The method comprises (a) incubating human fascicles with one or more mitogens for a priming period of three to fourteen days to produce primed fascicles, (b) incubating the primed fascicles with one or more tissue dissociation enzymes to produce primed Schwann cells, (c) culturing the primed Schwann cells at an initial Po density for a period of time to achieve no greater than 90% confluence, (d) expanding the population of Schwann cells by culturing the Schwann cells at an initial passage density for a period of time to achieve no greater than 90% confluence for at least two passages, and harvesting the population of human Schwann cells. The invention further provides an isolated population of Schwann cells obtained by the method described herein. In various aspects of the invention, the isolated population is provided in a composition.
