Synthesis of 1,3-diarylacetones from N-(arylacetyl)benzotriazoles via arylketene intermediates

Several 1-acylbenzotriazoles were synthesized and treated with sodium hydride to afford symmetrical ketones via the dimerization of intermediate ketenes followed by hydrolysis and the loss of carbon dioxide. © 1996 John Wiley & Sons, Inc.

Stereo‐ and Regioselective Thiolysis of 1,2‐Epoxides in Water

A simple, efficient, stereoselective, and highly regioselective procedure for the synthesis of β‐hydroxy sulfides by thiolysis of various 1,2‐epoxides in water as a solvent, using no catalyst and under very mild conditions, is described.     

Interaction of micellar casein and i-Carrageenan: Influence of high pressure

The effect of high-pressure treatment (HPT) (up to 950 MPa) on the rheological properties of a mixed system of i-Carrageenan (i-Car) + skim milk powder (SMP), expressed in terms of its micellar casein (MC) content, has been investigated. In the presence and absence of ionic calcium, with or without initial thermal processing, no significant effect has been found on the rheology or gelation/melting temperatures of pure i-Car even under harsh HPT conditions. But, in mixed systems, containing varying amounts of i-Car (up to 1 wt.%) and MC (up to 8 wt.%), substantial changes have been detected. Most significantly, at the higher molar ratios of MC, and particularly at the higher pressures (>400 MPa), the dispersions were not thermoreversible in gelation anymore, probably due to the strong interactions of disrupted casein micelles with i-Car molecules, as well as due to the formation of a dominant proteinaceous network.     

Solution of dual fuzzy polynomial equations by modified Adomian decomposition method

In this paper, we present some efficient numerical algorithm for solving dual fuzzy polynomial equations based on Newton’s method. The modified Adomian decomposition method is applied to construct the numerical algorithms. Some numerical illustrations are given to show the efficiency of the algorithms.     

Synthesis of 3‐Substituted Benzpyrid‐4‐imino‐2‐oxime Derivatives

Pyrazolone, Isoxazolone, Pyrimidinone, Pyrimidinothione, thiazolidinone and β‐lactam incorporating 2‐oximino benzpyrid‐4‐one derivatives have been synthesized by cyclocondensation addition reaction and cycloaddition of hydrazine hydrate, phenyl hydrazine, hydroxylamine, urea, thiourea, mercapto acetic acid, and chloroacetylchloride, respectively.     

Intrinsic theory of projective changes in Finsler geometry

The aim of the present paper is to provide an intrinsic investigation of projective changes in Finsler geometry, following the pullback formalism. Various known local results are generalized and other new intrinsic results are obtained. Nontrivial characterizations of projective changes are given. The fundamental projectively invariant tensors, namely, the projective deviation tensor, the Weyl torsion tensor, the Weyl curvature tensor and the Douglas tensor are investigated. The properties of these tensors and their interrelationships are obtained. Projective connections and projectively flat manifolds are characterized. The present work is entirely intrinsic (free from local coordinates) (arXiv:?0904.?1602 [math.DG]).
