Synergistic effects of various pyridine bases on the extractabilities of Co(II)-acetylacetonate (CoA2) into benzene have been studied. The expected variation of the distribution ratio with the pH of the aqueous phase was deduced mathematically and compared with the experimental results. The results show that the synergism is due to the formation and preferential extraction of the 1:2 adduct, CoA2B2, and the synergistic effect decreases with the following order: γ-picoline> β-picoline> 2,4-lutidine> ...

The following abundances (atoms per 106 Si atoms) were measured by neutron activation analysis in three carbonaceous chondrites of types I, II, III, and one enstatite chondrite of type I.

This abundance pattern supports the view that chondrites are a blend of two types of material: a high-temperature fraction (chondrules plus metal) from which the volatiles were lost, and a low-temperature fraction (matrix), which retained ...

Analyses are carried out by using a simplified model of the dynamic current-voltage characteristic of the Gunn diode oscillator. Experiments have been also carried out. For the self-excited mixers, an external signal was injected into the oscillator instead of the signal reflected by the reflector. For the effects of the moving reflector upon the oscillation frequency and dc current were investigated in the static condition.

Resonance modes of a triangular ferrite post are classified into those which correspond to each eigen-excitation in order to select operation modes of the Y circulator. Resonance frequency splits for two rotational phase eigen-excitations are also discussed.

An epimeric mixture of 24-hydroxy-[24-3H]vitamin D3 was synthesized by the reduction of 24-ketovitamin D3 by sodium borotritide. The epimeric mixture was converted to the trimethylsilylether derivatives and subjected to high-pressure liquid chromatography using silica gel columns to separate the 24-hydroxy-[24-3H]vitamin D3 isomers. The 24R-hydroxy-[24-3H] vitamin D3 induced calcification in rachitic rats while the 24S-hydroxy-[24-3H] vitamin D3 had little or no such activity. As both isomers of ...

These adducts have a cis-octahedral configuration except for Ni(hfa)2(py)2. The metal-oxygen stretching frequencies of the adducts in the 405–370 cm−1 region decrease along the series: nickel(II)>cobalt(II)>copper( ...

Operation modes of a waveguide Y circulator with a circular and a triangular ferrite post are investigated both theoretically and experimentally. Field analysis is carried out taking into consideration the field variation along the ferrite axis. Frequencies are calculated by assuming TM modes nearly agree with measured frequencies. It is shown that the circulator action occurs at frequencies where two HE modes interfere with each other, besides occurring at HE mode resonance frequencies. Effects ...

Hexagonal ferrite is used for a circulator at mm-wave frequencies. No external magnet is needed. The center frequency is 73.5 GHz, the bandwidth over which the isolation is greater than 20 dB is 2.4 GHz, and the insertion loss is 1.1 dB at the center frequency. The tensor permeability in a strong uniaxial field is determined. The dependence of the circulator bandwidth on an applied field is determined to show that the large uniaxial field of hexagonal ferrite contributes to the wideband performance ...

Although linear modulation methods can achieve high spectrum efficiency, very little attention has been directed to their use in mobile radio systems. This is mainly due to the fact that the nonlinearity of the transmitter power amplifier tends to spread the spectrum and thus eliminate any spectrum efficiency advantage gained through the use of linear modulation methods. In this paper, a linear modulation system is proposed, which solves the above difficulty and which gives higher spectrum efficiency ...
