Ethanol is "an alcohol product produced from corn, sorghum, potatoes, wheat, sugar cane, even biomass such as cornstalks and vegetable waste. When combined with gasoline, it increases octane levels while also promoting more complete fuel burning that reduces harmful tailpipe emissions such as carbon monoxide and hydrocarbons.Biodiesel is "a domestic, renewable fuel for diesel engines derived from natural oils like soybean oil, and which meets the specifications of ASTM D 6751." Or, for those of you who want a more technical definition, it is "a fuel comprised of mono-alkyl esters of long chain fatty acids derived from vegetable oils or animal fats. Also Biodiesel is made through a chemical process called transesterification "whereby the glycerin is separated from the fat or vegetable oil.Both forms of biofuel have definite environmental advantages over petroleum-based gasoline and diesel fuel.Ethanol contains 35% oxygen. Adding oxygen to fuel results in more complete fuel combustion, thus reducing harmful tailpipe emissions. Ethanol also displaces the use of toxic gasoline components such as benzene, a carcinogen. Ethanol is non-toxic, water soluble and quickly biodegradable.Biodiesel, on the other hand, "is the only alternative fuel to have fully completed the health effects testing requirements of the Clean Air Act. The use of biodiesel in a conventional diesel engine results in substantial reduction of unburned hydrocarbons, carbon monoxide, and particulate matter compared to emissions from diesel fuel. Looking forward for more interesting discussion on this.

Christine, This is from an old study done on bloat. Being involved with Great danes since 1963, we have had our share of bloat and have known many others who have gone through it. Bottom line is - no one really knows. It does run in some bloodlines so genetics can play a part. I have known dogs to bloat on empty stomachs, bloat on raw diets and bloat after just laying around the house. On the other hand, I have known dogs to eat dry food, drink lots of water, run around like crazy after eating and live to 10 or more. This is a horrible health issue that many breeds are affected by and each one of us with affected breeds can only do what we feel is best. So many dane, and other breeds, now tack their dogs as a normal procedure. Again, pros and cons of that. Jan

Its very likely. If you have areas where insulation can enter the living space (recessed lights that are not air tight, a/c boxes not sealed to attic flooring) then insulation particles may be entering this space when hvac system is in use. This will account for the dust & health problems. Having a blower door test will pinpoint areas of leakage. Put the mask back on & take a look in your attic at these areas. If you have recessed lights, & there are holes in the housing where you can see light then air can move through these holes. Feel around an a/c box where it meets the ceiling. If you feel a gap at this junction this is a leakage site also. Sealing ductwork at the plenum ( the origin of the ducts from the heating system ) should also be addressed, if necessary. Mastic products provide a long lasting air tight seal. Returns should also be sealed. Call your state's dept of energy to ask who to call for blower door testing. I do this testing & home owner's are amazed at leakage areas. Most are fairly easily sealed, it is just to know where to seal, and with what to seal. Best of luck.

NyefNyef By "called Blanco", I meant I telephoned Blanco's US HQ and asked them to find me their sink within a 200 mile radius of my home. They pointed me to their regional sales teams, who could not locate it readily available, or in their nat'l warehouse. They said most of the time, nobody really stocks them and they're all custom ordered. No matter. Amazon & FedEx came thru. cal Ditto! I'd love to FedEx them too. breezyThanks for answering my original question. My suspicion was that they weren't as good, just based on how often I see Blanco mentioned and never hear the other makers. And compared to what we've spent already on things, you're right that $100 is a small price to get exactly what we wanted exactly when we need it.
