Abstract: A system for drying grain includes a receiving bin defining a cavity therein and further includes intake and outlet ports. A conduit is operably connected to the receiving bin that includes a plurality of check valves and a stop valve. The system further includes a mechanism for introducing air at a selected flow rate into the conduit and a combustion source that includes a pilot gas light wherein fire is created that burns between 2000–3000 degrees Fahrenheit. The combustion source includes a flue positioned thereabove and a drain outlet extending substantially orthogonal to the conduit. A heat exchanger is connected to the combustion source including a fan and a filter operably connected thereto.

Abstract: A surface water runoff filtration device comprises an intake which is adapted to receive storm water and other surface water runoff. The surface water runoff flows from the surface through the intake to a point below the filter media, and then up toward the surface through the filter media. This device may be used in both catch basin storm drains and inline drains.

Abstract: The present invention provides methods for activating the immune systems of newborn animals and methods for enhancing the production performance of the animals. More particularly, the methods of the present invention involve the administration of compositions comprising mycrobacterial cell wall extract, most preferably cell wall extracts of Mycobacterium phlei.
