Bimetallic Cu/Mg, Ca, Ba mixed oxide compounds acted as catalyst in the dehydrogenation of tetradecanol into tetradecanal,
and were characterized by thermal gravimetric analysis, surface area, X-ray diffraction, temperature-programmed reduction
and desorption of CO2. Alkaline earth oxides increased the total basic site concentration in the order of Mg>Ca>Ba. A correlation was found between
the total basic site concentration and initial dehydrogenation rate.

The anion and cation radicals of vitamin K1 and its analog menadione were characterized using the magnetic resonance techniques of Electron Nuclear Double Resonance (ENDOR), Electron Spin Echo Envelope Modulation (ESEEM), and Electron Paramagnetic Resonance (EPR) at X-band and 2 mm-band. Theg-factor anisotropy of the radicals at 2 mm-band allow them to be distinguished from each other in the solid state. Theg-factor matrix of the radical anion of vitamin K1 is virtually identical with that reported for the reduced A1 acceptor in green plant photosystem I thus demonstrating that reduced A1 is the anion radical of vitamin K1. 相似文献

We consider a difference scheme for the heat equation with nonlocal boundary conditions containing a complex parameter γ. We single out stability domains in the complex γ-plane and derive a criterion for stability with respect to the initial data in the form of a condition on γ and the grid increments. 相似文献

We consider a weighted difference scheme approximating the heat equation with the nonlocal boundary conditions . We show that in this case the system of eigenfunctions of the main difference operator is not a basis but can be supplemented with associated functions to form a basis. Using the method of expansions in the basis of eigenfunctions and associated functions, we find a necessary and sufficient condition for stability with respect to the initial data in some energy norm. We show that this stability condition cannot be weakened by choosing a different norm. The above-mentioned energy norm is shown to be equivalent to the grid L 2-norm.
