Purpose. The purpose of the work is an investigation of biophysical properties of liquors of patients with a craniocereberal trauma. This investigation has been directed on definition of a degree of a brain defeat, the forecast of the further current of disease and development of methods treatment. Materials and methods. Liquor was undertaken from 62 patients with the diagnosis of an craniocereberal trauma. Research of thermo-impedancemetry of liquors was made with the help of equipment for measurement of temperature dependence of an electric impedance of ditches with a researched liquid. On the -shaped site?function of dependence of a full impedance from temperature the was observed. This site is due to globule-ball phase transition in liquor albumens. Result. It is shown, that numerical values of parameters of phase transition correlate with albumen concentration in liquor. Values of correlation factors are directly proportional to concentration of albumen. Conclusion. It is established, that numerical values of thermo-impedancemetry parameters of curves are directly connected to a degree of a brain defeat and can be used as diagnostic and prognostic criteria.

The phase transitions and thermal expansion of apatite-structured compounds with the general formula MII5(AVO4)3L (MII = Ca, Sr, Cd, Ba, Pb; AV = P, V, Cr, Mn; L = OH, F, Cl, Br, I) have been studied by high-temperature X-ray diffraction and differential thermal analysis. Polymorphic transition nature was explained on the basis of the structure data. Connection between thermal stability and peculiarities of thermal expansion, which were explained in assumption of composition and structure of apatites was ascertained.

Compounds in Ca10(PO4)6Cl2–Pb10(PO4)6Cl2 system were synthesized by solid state reaction. It was ascertained using DTA and X-ray diffraction methods that in the investigated system there are two fields because of the formation a compound with formula Ca7Pb3(PO4)6Cl2. The first area is the Pb10(PO4)6Cl2–Ca7Pb3(PO4)6Cl2 which is characterized by unbounded mixing of components. The second Ca7Pb3(PO4)6Cl2–Ca10(PO4)6Cl2 area has complicated character due to presence of decomposition processes. In spite of the presence of the one nature polymorphic transitions of Ca10(PO4)6Cl2 and Pb10(PO4)6Cl2 the same effects on all solid solutions were not observed.

In the present work the temperature dependences of pentalead tris(vanadate) chloride heat capacity have been measured for the first time in the range from 7 to 350 K. The experimental data were used to calculate standard thermodynamic functions, namely the heat capacity Cp◦ (T), enthalpy H◦(T)−H◦(0), entropy S◦(T)−S◦(0) and Gibbs function G◦(T)−H◦(0), for the range from T→0 to 350 K. The differential scanning calorimetry in temperature interval 298–1473K was applied to measure temperatures of phase transition and melting of compound under study. The high-temperature X-ray diffraction in range 298–1073K was used for the determining thermal expansion coefficients.

Compounds of composition Pb5(PO4)3FxCl1−x (0≤x≤1), which are synthetic analogues of minerals pyromorphite, flourapatite, and endlichite, were synthesized for the first time by high-temperature solid phase reactions. X-ray diffraction and IR spectroscopy were used to determine the structure of the compounds and revealed complete miscibility in the solid phase of the Pb5(PO4)3F–Pb5(PO4)3Cl binary system. Adiabatic reaction calorimetry was used to measure standard enthalpies of mixing and formation and show that the regular solutions model is applicable to the Pb5(PO4)3F–Pb5(PO4)3Cl system. Differential thermal analysis in tandem with high-temperature X-ray diffraction were used to study the phase diagram and characterize phase transitions.
