The only alternative that seems to solve Falk’s problem is to repeal the “just and reasonable” rate provision of the Federal Power Act. However, the probability this legislation would make it through Congress is virtually zero. In fact, recent versions of the national Energy Policy Act in Congress increase FERC’s authority and strengthen its mandate to set just and reasonable prices.
In the present paper we find necessary and sufficient conditions on the coefficients of a parabolic equation for convexity to be preserved. A parabolic equation is said to preserve convexity if given a convex initial condition, any solution Nike Air Force 1 Mid Canada
of moderate growth remains a convex function of the spatial variables for each fixed time.
The excited electronic states in the ionic crystal MgO have been studied by electron energy-loss spectroscopy. Structure observed above the thresholds for excitation from the Mg 2p, 2s and 1s core levels shows the final states to be predominantly excitonic levels of the Mg2+ ion. Comparison with the known states of the Mg2+ free ion indicates that solid-state shifts and splittings are small.
We prove that for positive integers n and k and a positive even integer m, the odd integer set 1, 3, 5, …, 2n−1 contains k disjoint subsets having a constant sum Nike Air Force 1 Low m if and only if 4k⩽m⩽n2/k, n2−mk≠4n−2 or n≠4k.
