It is unusual to find systemic failure in the absence of liver metastases,[1] although the portosystemic shunting that exists at the anorectal junction does permit hematogenous spread outside the portal circulation to the internal iliac vessels and the cava.
A flexible-fuel vehicle (FFV) or dual-fuel vehicle (colloquially called a flex-fuel vehicle) is an alternative fuel vehicle with an internal combustion engine designed to run on more than one fuel, usually gasoline blended with either ethanol or methanol fuel, and both fuels are stored in the same common tank.
Sure, they are gasoline engine vehicles, but theyâve been modified to operate smoothly on any mixture from straight gasoline and E10 up to E85 (a blend of 85 percent ethanol and 15 percent gasoline). In addition, modifying a conventional auto to make a flex fuel vehicle is inexpensive. FFV technology is estimated to cost roughly $100 per vehicle at the time of manufacture. Whatâs more, retrofit kits are available for many cars for about $400.
