Titanium Membranes with Hydroxyapatite/Titania Bioactive Ceramic Coatings: Characterization and In Vivo Biocompatibility Testing.

Titanium membranes and meshes are used for the repair of trauma, tumors, and hernia in dentistry and maxillofacial and abdominal surgery. But such membranes demonstrate the limited effectiveness of integration in recipients due to their bioinertness. In this study, we prepared titania oxide (by microarc oxidation) and/or HAp (by electrophoresis deposition) coatings with alginate soaking.

Flame propagation in two-dimensional solids: Particle-resolved studies with complex plasmas.

Using two-dimensional (2D) complex plasmas as an experimental model system, particle-resolved studies of flame propagation in classical 2D solids are carried out. Combining experiments, theory, and molecular dynamics simulations, we demonstrate that the mode-coupling instability operating in 2D complex plasmas reveals all essential features of combustion, such as an activated heat release, two-zone structure of the self-similar temperature profile ("flame front"), as well as thermal expansion of the medium and temperature saturation behind the front. The presented results are of relevance for various fields ranging from combustion and thermochemistry, to chemical physics and synthesis of materials.

[The concept "a case in outpatient treatment" in military policlinic activity].

Substantiates the necessity of transition of military policlinics to the accounting system and evaluation of their activity on the finished cases of outpatient treatment. Only automating data-statistical processes can solve this problem. On the basis of analysis of the literature data, requirements of the guidance documents and observational results concludes that preliminarily should be done revisal (formalisation) of existing concepts of medical statistics from the position of information environment which in use - electronic databases.

[Optimization of work of polyclinic in medical supply of attached contingents on the base of using of informational technologies].

The article presents review of experience of forming of information system of recording of visiting of policlinics and analyze of treatment measures. Functioning of this system on the base of local computer net permitted considerably improve indexes of work of policlinics.

[Description of the binding of chitosan to DNA at different ionic strengths in terms of the theories of ion condensation and adsorption].

The binding of chitosan molecules to DNA in solutions of different ionic strength has been studied. The data were analyzed in terms of the model of ion condensation and the thermodynamic theory of the binding of protracted ligands to DNA. Combining these approaches made it possible to estimate the sterical and energetic characteristics of chitosan-DNA binding and establish the dependence of the chitosan-DNA binding constant on the ionic strength of solution.
