The present invention relates to amniotic fluid specific polypeptide and a method for detecting rupture of the amniotic membranes. The present pool cover consists of a series of planar panels composed of transparent, durable plastic material and a flotation portion disposed about the periphery of the panels. Methods for producing a maize plant containing in its genetic material one or more traits introgressed into PH1D9K through backcross conversion andor transformation, and to the maize seed, plant and plant part produced thereby. The second calculator calculates an actual energy consumption that the second motor requests to maintain rotating speed of the engine. The receiving portion receives the ornament insertion portion so as to be exposed on a side of the outer peripheral portion of the trim main body. A control circuit, responsive to the increase in voltage within the control signal, dynamically adjusts the operating frequency of a resonant inverter so that the arcing condition is extinguished.
