. Purpose. The regularities of a simultaneous increase in microhardness and plastic properties of the surface of titanium alloy VT9 are investigated. The hardness and Young’s modulus of thin surface layers are determined. Methodology and Approach. The methods employed are based on the use of nanosecond laser pulses initiating a complex of physical and chemical processes. The method of continuous indentation with a maximum load of 0,05 N is used. The mechanical properties of surface structures of titanium alloy VT9 after laser treatment are analyzed. Using the load-penetration diagrams, the following values were calculated: the contact depth of penetration, the stiffness of the contact ‘indenter–material’ pair, the projection area of the unreconstructed print, and the effective Young’s modulus. On the basis of the Oliver–Pharr method, the nano- and microhardness, as well as the modulus of longitudinal elasticity of the surface layers of a titanium alloy are estimated Results . It is found that as a result of processing, the microhardness of the surface increases by 2,5–4,5 times, and the Young’s modulus by 1,1–1,5 times. A distinctive feature of the proposed treatment method is good adhesion of the surface layer with the bulk material, which reduces the probability of high mechanical stresses and cracking. Theoretical and Practical implications . The proposed method of laser processing makes it possible to form hardened surface layers in a normal atmosphere, which contributes to a significant simplification of the technological process and reduces its cost.

The aim of this work is to analyze the dependence of the electrical conductivity of a thin metal film on the nature of the dependence of the specularity coefficient on the angle of incidence of electrons on the metal surface. The dependence of the specularity coefficient on the angle of incidence is considered, satisfying the Andreev condition. Methodology . A model boundary condition is considered, taking into account the dependence of the specularity coefficient on the angle of incidence of electrons on the metal surface. Results. The considered model of the boundary conditions in the limiting cases transforms into the Fuchs boundary condition and into the Soffer boundary condition. In addition, the considered boundary condition, in contrast to the Fuchs and Soffer boundary conditions, satisfies the Andreev criterion for an almost tangential incidence of electrons on the metal surface. Research implications. The results obtained can find application in the study of the interaction of electromagnetic radiation with a thin metal film, wires, in small metal particles and in describing the skin effect in a metal.

By an elastic solid we mean a mathematical model of a continuous medium, in which the specific density of free energy is a function of only temperature and derivatives of displacement vectors. In the framework of equilibrium thermodynamics, the isothermal principle of virtual work for an elastic solid is obtained. Results. The isothermal principle of virtual work for an elastic solid is derived. The conditions for mechanical equilibrium inside and on the surface of an elastic solid are obtained. Research implications. For a given function of the specific density of free energy and the known value of the temperature, it is possible to determine the dependence of the displacement functions on the coordinates that characterize the deformed state of the considered elastic solid.

The theory of evolution of the early universe predicts the formation of black holes of different mass. Depending on the physical processes, black holes can be formed with masses up to 10 27 g. Because of the Hawking effect of quantum evaporation of black holes, black holes with masses over 10 15 g have survived to our time. The aim of this work is to calculate the intensity of gamma radiation from the primordial black holes, to explain the diffuse gamma spectrum of the Universe’s radiation from them in the range of 10–100 MeV, and to estimate their contribution to dark matter of the Universe. Methodology. The intensity of radiation from an ensemble of black holes is calculated by using an approximation in the form of the δ -function for the radiation of the absolutely black body. Results . It is shown that if the function of the masses of primordial black holes is N(M) = K · M – γ , the intensity of Hawking’s radiation is I( ν ) ~ ν γ . Since the background radiation of the Universe in the range of quantum energies 10–100 MeV has the form of I( ν ) ~ ν –1,3 MeV/cm 2 MeV ⋅ ster, then N(M) = K ⋅ M 1,3 . In this range there emit primary black holes with masses of 10 15 g and sizes of an electron. Research implications. It is shown that the extrapolation of the resulting distribution of masses to the values of 5·10 21 g allows one to explain the observed mass of dark matter in the Universe. At the same time, the concentration of these black holes with masses comparable to the masses of asteroids is such that there may be hundreds of them in the solar system.

Objectives Xanthoastrocytoma (XA) is a low-grade glial tumor seen in young adults and there is lack of robust data on treatment of this rare tumor. In this systematic review and individual patient's data analysis, we aimed to look into the demography, pattern of care, survival outcomes, and prognostic factors in patients with both Grade II and III XA. Methods A comprehensive search was conducted with the Medical Subject Heading terms: "Xanthoastrocytoma; Pleomorphic Xanthoastrocytoma; Anaplastic Xanthoastrocytoma; Xanthoastrocytoma AND treatment; and Anaplastic Xanthoastrocytoma AND survival" to find all possible publications. Results A total of 325 individual patients from a total of 138 publications pertaining to XA were retrieved. Median age of the entire cohort was 19 years. About 56.1% of the patients underwent a gross total resection (GTR) and 31.4% underwent a subtotal resection. Nearly, 76.6% of the patients had a Grade II tumor and adjuvant radiation was delivered in 27.4% of the patients. Estimated 2- and 5-year progression-free survival (PFS) were 68.5 and 51.2%, respectively. Age, grade, and extent of surgery were significant factors affecting PFS. Estimated 2- and 5-year overall survival (OS) was 88.8 and 78%, respectively. The median OS for Grade II and Grade III tumors were 209 and 49 months, respectively. Age and extent of surgery were significant factors affecting OS. Conclusion XA is a disease of young adults with favorable prognosis. Younger patients (<20 years), patients who undergo a GTR, and patients with a lower grade tumor have a better treatment outcome.

. The influence of the composition of the reagent flow on the formation conditions and the structure of ZnO-based layers is studied. It is shown that a key reserve in increasing the electrical conductivity and mobility of charge carriers of Ga-doped ZnO transparent electrodes is to increase the structural perfection of the layers. Analysis of the obtained results shows that an increase in the partial pressure of metal vapors in the gas phase entails a corresponding increase in the mobility of the components and an increase in the crystalline perfection of the synthesized polycrystalline layers.
