Experimental, Numerical and Analytical Evaluation of Load-Bearing Capacity of Cold-Formed S-Beam with Sectional Transverse Strengthening.

The article provides information about strengthening cold-formed thin-walled steel beams made of the sigma profile. An innovative concept for sectional transverse strengthening of thin-walled beams subjected to concentrated forces was investigated. The proposed solution's novelty lies in attaching the sectional transverse strengthening to the beam's cross-section, employing a point crimping technique.

Ultra-Fast Impedimetric Immunoassay for Detection of Using Carbon Electrode with Nanodiamonds Film.

This publication presents the results of work on the development of a quick and cheap electrochemical immunosensor for the diagnosis of infections with the pathogen . The research was carried out on the basis of the modification of the well-known glassy carbon (GC) electrodes. The surface of the GC (glassy carbon) electrode was covered with a film made of nanodiamonds, which increased the number of sites for the attachment of anti- antibodies.

Detection of seroconversion to bovine herpesvirus 1 related alphaherpesvirus and bovine viral diarrhea virusin Polish free-living deer.

There are several infectious agents of domestic cattle that can also be present in free-living ruminant populations. These include bovine herpesvirus 1 (BoHV-1) and bovine viral diarrhea virus (BVDV) which are the causative agents of infectious bovine rhinotracheitis and bovine viral diarrhea, respectively. The study was conducted on serum samples from 59 red deer, 24 roe deer, and 3 fallow deer (86 in total), originating from two geographically separate areas of Poland.

Pathogenicity of three genetically diverse strains of PRRSV Type 1 in specific pathogen free pigs.

Studies from Eastern European countries proved that porcine reproductive and respiratory syndrome virus Type 1 (PRRSV-1) harbours high genetic diversity and that genetically divergent subtypes 2-4 circulate in this area. In the present study, we compared the pathogenicity of two different PRRSV-1 subtype 2 strains and a strain representing PRRSV-1 subtype 1. Four groups of 8-week-old specific pathogen free pigs were either infected with subtype 2 strain ILI6, subtype 2 strain or BOR59, subtype 1 strain 18794, or mock inoculated.

Immunohistochemical evaluation of superoxide dismutase (Cu/Zn SOD) concentrations in erythrocytes of dairy cattle and farm-raised deer by a computer-assisted analysis of microscopic images.

The effectiveness of the immunohistochemical method in determining Cu/Zn SOD concentrations in red blood cells of dairy cattle and farm-raised deer was evaluated by a computer-assisted analysis of microscopic images and scanning technique. Superoxide dismutase (Cu/Zn SOD) concentrations in erythrocytes were determined in smears of whole blood samples collected from 16 Polish Holstein-Friesian cows and 22 farm-raised deer in spring. Mouse anti-bovine SOD (Cu-Zn) monoclonal antibodies (2F5, Serotec) were used in 1:50 dilution.
