The speckle patterns scattered from the boundary surfaces of a birefringent slice are imaged on a photographic plate. The method consists in taking account of the variations of the statistical properties of the two superimposed speckle patterns. The results are similar to those obtained by observing this thin slice in a classical parallel or crossed polariscope. This method does not need the slicing of the model.
Small phase-mismatch between the fundamental and high order polarization in the cut-off region, allowing macroscopic phase-matching to be satisfied for these harmonics can be used for generation of extreme ultraviolet radiation with high flux, high coherence and few harmonic orders in a semi-infinite argon gas Nike Air Max 97
We describe a new software package, named Air Max
SumCracker, for proving and finding identities involving symbolic sums and related objects. SumCracker is applicable to a wide range of expressions for many of which there has not been any software available Air Max 97 Og up to now. The purpose of this paper is to illustrate how to solve problems using that package.
Acylation of 3-methyl-2,3-bis(trimethylsiloxy)-l-butene (PhLi) with (E)-2-methyl-2-butenoyl chloride gives the corresponding 3(2H)-furanone derivative, which can be readily converted to the naturally occurring antitumor agent Geiparvarin by two steps.
