The invention is related to anti-viral phosphinate compounds, compositions containing such compounds, and therapeutic methods that include the administration of such compounds, as well as to processes and intermediates useful for preparing such compounds. A cross-sectional view of the rounded square lens cut along its diagonal forms a semicircular surface so as to emulate a hemispherical lens in areas close to the diagonal. Further, the plurality of bristles have a bristle length. Depending upon the mode of the QAMCW gain switch, the AGC circuit either attenuates the power level of the signal or bypasses the signal. Then, the inventory is rated as high, normal, or low impact based on their scores compared with the mean and a standard deviation for all scores. A circumferential recessed section, which is recessed inward in the tire width direction and extends in the tire circumferential direction, is formed on the outer surface of the tire side section, and turbulence-generating protrusions are provided on the circumferential recessed section.
