The enzyme immunoassay of soil suspensions was performed using antibodies against the lipopolysaccharides of Azospirillum brasilense model strains in order to assess the monthly population dynamics of the A. brasilense Sp245 introduced into the soil samples in laboratory simulation experiments and to determine the abundance of azospirilla in the various(More)
A novel approach of normal ECG recognition based on scale-space signal representation is proposed. The approach utilizes curvature scale-space signal representation used to match visual objects shapes previously and dynamic programming algorithm for matching CSS representations of ECG signals. Extraction and matching processes are fast and experimental(More)
The genus-specific surface protein antigens of Azospirillum brasilense strains were visualized immunochemically. The procedure used for cell sample preparation was optimized to ensure that the surface protein structures were detected on cells in situ. Gold and gold-silver nanoparticles were conjugated to antibodies raised against the flagellin of A.(More)
Immunoelectrophoresis and immunodiffusion analysis with antibodies to whole intact cells of the type strain of nitrogen-fixing soil bacteria Azospirillum brasilense Sp7 revealed at least three conservative surface immunogenic proteins of azospirilla. Cross-reactions with these proteins made it possible to use the above antibodies for the detection of(More)
Methods of the differential game theory are applied to the problem of overpassing a vertical obstacle by an aircraft. An algorithm is suggested for constructing the aircraft control by the thrust and elevator that is adaptive with respect to the unknown level of a wind disturbance. The state constraint on the pitch angle is implicitly taken into account.(More)
