A technique for forming Langmuir films from antibodies based on an amphiphilic polyelectrolyte was developed. The physicochemical and immunochemical properties of the Langmuir films obtained were studied. The interaction of HBsAg with the films was found to be described by a model with one binding site, whereas that of HBsAg with antibodies adsorbed on a polystyrene plate, by a model with a positive cooperativity. The use of the novel Langmuir films from antibodies increases the sensitivity of the immunoenzyme assay. 相似文献

Radical copolymerization is considered theoretically taking into account the effect of complexing on the configurational statistics of macromolecules formed. Akinetic model has been developed that considers, apart from the ordinary addition of single monomer units to a propagating chain, the possible addition of monomer unit pairs along with a complexing agent in the form of a ternary complex. Within the framework of this model, the problem of calculating the probabilities of formation of any sequences of monomer units (taking into account their microtacticity) in a macromolecule has been rigorously solved as well as the problem of finding the composition distribution of the copolymer formed. It has been shown that this distribution is described by a conventional Gauss law and the appropriate parameters are given. Possible generalizations of the suggested approach are indicated. 相似文献

The problem of gravitational unloading of the angular momentum of inertial actuators of a spacecraft in the pitch channel
for circular and elliptic orbits is considered using the band theory of modal control. Control laws for gravitational unloading
and stabilization of a given spacecraft position unambiguously determined by the object parameters and given coefficients
of characteristic equation are obtained. 相似文献

We propose a method for the recalculation of dynamic stresses from a photoelastic model to a real solid in plane problems of the mechanics of orthotropic bodies. To estimate the accuracy of the method, we recalculate stresses for a problem with known theoretical solution. 相似文献

Test results for different high-strength steel specimens in static and impact tension and compression over a wide range of strain rates were summarized. These data were used to calculate the generalized deformation curve. The calculations based on this curve were compared with the experimental data on impact indentation with the conical indenter to evaluate the applicability of this method for studying the behavior of metals at high strain rates. 相似文献

Based on band matrices, a new formula for finding polynomial coefficients of the numerator of the transfer function for a linear single-input single-output system is derived. Its properties are studied for analyzing and synthesizing linear systems with many outputs, as a result of which a method is developed for the synthesis of the specified polynomial of zero dynamics (specified output) for a linear system with many outputs. 相似文献

A comparative study of the structure of uniaxially-oriented bulk samples of linear PE of various molecular weights over a wide range of draw ratios has been carried out by means of small and wide angle X-ray analysis, NMR-spectroscopy and DSC. The structure of oriented high molecular weight PE samples, prepared by drawing single crystal mats to draw ratios up to 200, have also been studied. A large number of unfolded tie-molecules have been found to exist in the trans-conformation in PE amorphous regions. These tie-molecules, which connect the adjacent crystallites along the axis of orientation, and are not large crystals, account for the high mechanical properties of these samples. It has been shown that in the course of the orientation process, chain unfolding in the amorphous regions is accompanied by the formation of continuous linear systems consisting of several coherent crystallites and tie-molecules. These are coherently aligned along the macromolecular axis. 相似文献
