The present invention provides a method and system for controlling packet flow through a protocol stack. The display utilizes the persistence of vision approach and presents a series of dynamic images and text on each cycle. The processing electronics can determine presence of the hazard in response to data related to returns received by the weather radar antenna and data from a lightning sensor. lactis JCM 1253, Bifidobacterium animalis subsp. In addition, the antenna dimensions can be markedly minimized by maximally reducing the unit cell size. A relatively thicker transverse member joins the upright posts such that the upper ends thereof are spaced farther apart than the lower ends thereof.
