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.
To better judge ethanol's strengths and weaknesses, we decided to buy a flex-fuel vehicle (FFV) and put E85 to the test. E85 is an ethanol mixture promoted as an alternative to gasoline. We put our 2007 Chevrolet Tahoe FFV through our full series of fuel-economy and acceleration tests while running on each fuel.
