Determination of Different Biological Factors on the Base of Dried Blood Spot Technology

It is well-known that distinct biological indices (analytes) have distinct variability. We try to use some mathematical algorithms to pick out a set of blood parameters which give an opportunity to retrieve the initial volume of the blood spotted, and use it to calculate exact concentrations of analyts interesting to a physician. For our analysis we used the database of biochemical blood parameters obtained in Russian Scientific Center of Roentgen-Radiology during 1995-2000, which includes more than 30000 of patients.Comment: 5 page

Applications of Pulsed Electromagnetic Fields in Powder Materials High Speed Forming

In current article, applications of electromagnetic pulsed fields for processing of powder materials are presented. The main attention is paid to the following applications of pulse electromagnetic fields in powder metallurgy and allied industries: pressing of powders, manufacturing of powder coatings, and conveying of ferromagnetic powders by means of pulsed electromagnetic field

Reduction of the Vibrations Caused by Transport to the General Post-Office of Moscow

After the completion of base reinforcement with cast-in-place piles, instrumental analysis of foundation vibration parameters was made on the basis of the vibration survey results. The analysis showed a considerable decrease in the level of vibrations caused by transport

SYMMETRIC REPRESENTATIONS OF HOLOMORPHIC FUNCTIONS

In this article a class of symmetric functions is defined and used in some special representation of holomorphic functions. This representation plays an important role in transitions from concrete problems of projective description to equivalent problems of inductive description and finds multiple applications in questions connected with spectral synthesis of differential operators

Investigations of Properties of Powdered Ferromagnetic Sorbents

The paper examines possible application of certain disperse materials based on iron powders as ferromagnetic sorbents for collecting the oil products spilled on the water surface. Sorption ability is defined for the investigated ferromagnetic sorbents

Ethyl 2-(4-hydr­oxy-1-methyl-2-oxo-1,2-dihydro­quinolin-3-yl)acetate

In the title compound, C14H15NO4, the bicyclic fragment and the ester group form a dihedral angle of 86.7 (2)°. Inter­molecular O—H⋯O and C—H⋯O hydrogen bonding connects mol­ecules into a helix along the crystallographic b axis

Induced magnetic anisotropy features in FeCrSiBNbCu nanocrystalline alloy: Role of stress distribution proven by direct X-ray measurements

Fe73.5-xCrxSi13.5B9Nb 3Cu1 (x = 1, 2, and 3) amorphous ribbons were prepared by single roller rapid quenching technique. Both conventional and stress annealing at 520 C for 2 h at the value of the specific load of 150 MPa resulted in the formation of a nanocrystalline structure with average grain size about 13 nm. No significant differences in crystallite size were observed for all samples under consideration. The crystallite orientations were practically isotropic indicating no texture in the samples of all types. For all conventionally annealed ribbons a longitudinal effective magnetic anisotropy with an easy magnetization axis parallel to the ribbon axis was observed. For all stress annealed ribbons a transverse induced magnetic anisotropy with the anisotropy constant value of about 1800 ± 50 J/m3 was evident. Induced magnetic anisotropy features in FeCrSiBNbCu nanocrystalline alloy, namely an importance of the stress distribution was proven by direct X-ray measurements. A very good correlation between the induced magnetic anisotropy constant values and anisotropic stress distribution was observed. © 2013 Elsevier B.V. All rights reserved
