Effects of nutrition characteristics on blood lipids in patients with dyslipoproteinemia

Prevalence of risk of ischemic heart disease, such as nutrition and dyslipoproteinaemias are discussed. The interrelation of these risk factors with blood lipids was examined. It was found that risk factors are widespread, and population has low knowledge about their significance. Food, contained surplus of cholesterol, saturated fats, carbohydrates and deficiency of polyunsaturated fat acids increased atherogenic blood lipids and decreased antiaterogenic lipoproteins.     

Synthesis and properties of actinide dimolybdate complexes M<Subscript>2</Subscript>[AnO<Subscript>2</Subscript>(MoO<Subscript>4</Subscript>)<Subscript>2</Subscript>]·H<Subscript>2</Subscript>O (M = Rb,Cs; An = Np,Pu)

New Np(VI) and Pu(VI) dimolybdates Rb₂NpO₂(MoO₄)₂·H₂O (I), Cs₂NpO₂(MoO₄)₂·H₂O (II), Cs₂PuO₂(MoO₄)₂·H₂O (III), and Rb₂PuO₂(MoO₄)₂·H₂O (IV) were synthesized under hydrothermal conditions. The crystal structures of the compounds were determined, and their absorption spectra in the UV, visible, and IR ranges were measured. The compounds crystallize in the monoclinic system. Their crystal structure is based on [AnO₂(MoO₄)₂]_n^2n– anionic layers (An = Np, Pu) formed by (AnO₂)O₅ pentagonal bipyramids and MoO₄ tetrahedra, sharing common vertices. Each An atom in the layer is bonded to other five An atoms via MoO₄ tetrahedra with the formation of a 4343² network. The effect of the ionic radius of the outer-sphere cation on the parameters of the crystal structure and features of the absorption spectra is discussed.     

Preparation of thermoelectric materials based on higher manganese silicide

Rhenium-doped higher manganese silicide based materials have been prepared by hot pressing. It has been shown that the pressing temperature of the materials can be lowered by adding titanium as a reductant or by sonication during pressing. The average thermoelectric figure of merit of the materials in the temperature range 600–900 K is Z ≅ 0.7 × 10⁻³ K⁻¹.     

Recording high-diffraction-efficiency holograms on a photosemiconductor-liquid crystal structure

Experimental real-time holograms were recorded on a structure comprising a liquid crystal and a p-i-n-diode based on a hydrogenated amorphous silicon. The holograms offer unprecedented diffraction efficiency at acceptable spatial frequencies.     

Fire-resistant hydrocellulose fibres

Conclusions A comparative study of the reactivity of various types of hydrocellulose fibres in the reactions of graft copolymerization and ammonolysis has been carried out.The advantage of the fire-protective treatment of hydrocellulose with T-2 in the presence of urea has been demonstrated.Values of the activation energy of the thermal decomposition process of fire-protected hydrocellulose fibres prepared using various fireproofing agents have been calculated.Translated from Khimicheskie Volokna, No. 3, pp. 37–38, May–June, 1984.     

Transition probabilities for 5s-5p, 5p-5d, 4f-5d, and 5d-5f transitions in Ag-like ions with Z = 50-86

The wavelengths, electric dipole transition probabilities, and oscillator strengths are calculated for transitions between low-lying states (5s-5p, 5p-5d, 4f-5d, and 5d-5f) in the silver isoelectronic sequence (50 ? Z ? 86) using relativistic perturbation theory with a zero-approximation model potential. The results are compared with the corresponding data of the relativistic Hartree-Fock theory and the relativistic many-body perturbation theory. The results of these three theoretical approaches are compared with available experimental data for the level lifetimes. Possible reasons for some disagreements are discussed.
