A light fixture configured for attachment to a standard ceiling fixture junction box includes a metal base, a printed circuit board, a circular array of LEDs, and a domed cover. The metal base has a hole pattern that matches a mounting screw hole pattern of the standard ceiling fixture junction box. The printed circuit board is attached to a bottom surface the metal base. The circular array of LEDs is attached to an outer perimeter of the printed circuit board. The domed cover is attached to the bottom surface of the metal base and covers the printed circuit board and the circular array of LEDs. The domed cover is molded from clear plastic through which light from the LEDs may pass.

A circular grazing system for poultry and/or livestock. The circular grazing system including a center pivot structure installed at a field. The center pivot structure may have a center pivot axis. The field may be a poultry and/or livestock grazing field. The circular grazing system for poultry and/or livestock may include an enclosure for containing poultry and/or livestock. The enclosure may extend generally radially from the center pivot structure to a circumference of the field. The enclosure may be rotably coupled to the center pivot structure such that the enclosure rotates around the center pivot axis.

A ventilation apparatus for ventilating a building. The ventilation apparatus comprises a casing comprising: a cavity for housing a removable heat-exchange cartridge; a service door providing access to the cavity; a primary and secondary pathways fluidly connecting the inside of the building to the outside of the building, wherein the primary pathway and the secondary pathway cross the cavity along about perpendicular axes; a primary ventilator for forcing an airflow in the building through the primary pathway; and a controllable secondary ventilator for forcing a controllable airflow through the secondary pathway. The ventilation apparatus, when the casing houses the heat-exchange cartridge, has the primary ventilator forcing an inflow of air through the primary pathway, and (ii) the controllable second ventilator for controllably forcing either an outflow or an inflow of air through the secondary pathway. The ventilation apparatus, without heat-exchange cartridge, has only inflow(s) forced through the pathway(s).
