1-3 Butadiene, an important industrial chemical and a common environmental air pollutant, has been shown to be a weak carcinogen in the rat, but a potent carcinogen in the B6C3F1 mouse. This species difference makes risk extrapolation to humans difficult, and the underlying mechanism must be clarified before meaningful risk extrapolation to humans can be made.

And he who wields white wild magic gold is a paradox - for he is everything and nothing, hero and fool, potent, helpless - and with one word of truth or treachery he will save or damn the Earth because he is mad and sane, cold and passionate, lost and found.

The most potent muse of all is our own inner child.

If winds are the spirit of the sky's ocean, the clouds are the texture. Their is easily the most uninhibited dominion of the earth. Nothing in physical shape is too fantastic for them. They can be round as apples or as fine as string, as dense as a jungle, as wispy as a whiff of down, as mild as puddle water or as potent as the belch of a volcano. Some are thunderous anvils formed by violent up drafts from the warm earth. Some are ragged coattails of storms that have passed. Some are stagnant blankets of warm air resting on cold. I have seen clouds in the dawn that looked like a pink Sultan with his pale harem maidens and a yellow slob of eunuch lolling impotent in the background.

The world could not long ignore a holy church. The church is not despised because it is holy: it is despised because it is not holy enough. There is not enough difference between the people inside the church and those outside to be impressive. A church in which saints were as common as now they are rare would convict the world, if only by contrast. Sanctity cannot be ignored. Even a little bit is potent. So far from the gates of hell prevailing against it, it hammers on their triple steel.

Our risk models are based on at least 50 assumptions, none of which has been scientifically demonstrated. For example, we assume that there is no difference between continuous (as in animal tests) or intermittent (as in human experience) dosages. But that ignores our growing knowledge of the way in which DNA repairs the human system . . .We feed rodents `all-you-can-eat' buffets every day, yet we know that caloric intake is the single greatest contributing cause of cancer [in rodents]. In fact, we found you can modify the cancer causing impact of one of the most potent carcinogens from 90% down to less than 3%, just by cutting caloric intake 20%.

In really hard times the rules of the game are altered. The inchoate mass begins to stir. It becomes potent, and when it strikes, it strikes with incredible emphasis. Those are the rare occasions when a national will emerges from the scattered, specialized, or indifferent blocs of voters who ordinarily elect the politicians. Those are for good or evil the great occasions in a nation's history.

The really potent part of love is that it allows you to carry around beliefs about yourself that make you feel special, desirable, precious, innately good. Your lover couldn't have seen these qualities in you, even temporarily, if they weren't part of your essential being.

A reduction in beef and other meat consumption is the most potent single act you can take to halt the destruction of our environment and preserve our natural resources. Our choices do matter.

|
No power on earth or above the bottomless pit has such influence to terrorize and make cowards of men as the liquor power. Satan could not have fallen on a more potent instrument with which to thrall the world. Alcohol is king!

|
A common allegiance to form of expression that is identified with no single national unit is likely to prove one of the most potent symbols of the freedom of the human spirit that the world has yet known.
