Studying the Plastic Deformation of Cu-Ti-C-B Composites in a Favorable Stress State.

Composites with a copper matrix attract the attention of researchers due to their ability to combine high ductility, heat conductivity, and electrical conductivity of the matrix with the high hardness and strength of the reinforcing phases. In this paper, we present the results of studying the effect of thermal deformation processing of a Сu-Ti-C-B composite produced by self-propagating high-temperature synthesis (SHS) on its ability to deform plastically without failure. The composite consists of a copper matrix and reinforced particles of titanium carbide TiC (sized up to 1.

Corrective exercises in multimodality therapy of idiopathic scoliosis in children - analysis of six weeks efficiency - pilot study.

The program of the special corrective exercises according to Schroth method in H.R. Weiss modification was carried out in multimodality conservative therapy of idiopathic scoliosis in our clinic.

[Current approaches to laboratory diagnosis of syphilis].

The efficiency of chemiluminescence immunoassay (CIA) used as a treponemal test in the serological diagnosis of syphilis was evaluated, by applying the serum samples of 219 patients screened for syphilitic infection. The efficiency of CIA was evaluated in two steps: (1) comparison of the results of tests using the IMMULITE 2000 Syphilis Screen and LIAISON Syphilis screen reagent kits; (2) that of the results of tests applying the IMMULITE 2000 Syphilis Screen and Recombi Best antipallidum-summary antibodies kits. A 100% correlation was found when comparing the results of tests employing the IMMULITE 2000 Syphilis Screen and DiaSorin LIAISON Syphilis Screen kits (n=66).

[The protein antigens of Streptococcus pneumoniae].

Protein preparations of three S. pneumoniae strains belonging to different serological types according to the structure of their capsular polysaccharides have been analyzed. Immunoblotting with antiserum to a protein preparation isolated from one strain, pooled serum of patients with pneumococcal infection and individual sera of such patients have revealed that different S.

[Phototransformation of radicals appearing in the result of peptide decarboxylation].

Photoreactions of peptides Ala-Gly-Gly and Gly-Gly-Gly-Gly in the presence of potassium ferricyanide at 77 K were studied by modeling of ESR spectra. There were obtained parameters of ESR spectra of primary radicals of the peptide glycine residue appearing after decarboxylation, and of the secondary acyl radicals. Dependence of the second integrals of the experimental and triplet and singlet ESR spectra on irradiation time within wave lengths 410-510, 330-390 and greater than 530 nm was measured and discussed.
