Let Sr be the blow-up of P 2 in r general points, i.e., a smooth Del Pezzo surface of degree 9 − r. For r ≤ 7, we determine the quadratic equations defining its Cox ring explicitly. The ideal of the relations in Cox(S8) is calculated up to radical. As conjectured by Batyrev and Popov, all the generating relations are quadratic.

Elemental sulfur (S8) was found to react with [(TMPA)CuI(CH3CN)]+ to form the trans-mu-1,2 end-on disulfide complex [(TMPA)Cu-S-S-Cu(TMPA)]2+. The X-ray structure of this centrosymmetric disulfide complex shows a Cu(1)-S(1) bond length of 2.280(2) A and a S(1)-S(1A) bond length of 2.044(4) A.

Overwhelming physical evidence has been present for twenty-five years that Venus is a hot new planet, which we maintain resulted from the high velocity impact (> 10 43 ergs) on Jupiter about 6,000 years ago. Up-welling radiation measurements from five independent Pioneer Venus probes all agree that Venus is radiating 250 times more energy than the Earth. The interior is completely molten with a...
