Development of a detector based on a CVD-diamond for the use in radiotherapy facilities
High radiation hardness, chemical resistance, high temperature operation capabilities stimulate a growing interest
to use diamond materials as detectors of ionizing radiation. Samples of CVD-diamond materials in sizes 4Γ3 mm
and 4Γ1 mm with thickness from 50 microns up to 500 microns have been grown in INR RAS using a DC glow discharge
in a mixture of gases CH4/H2 on molybdenum substrates.ΠΡΡΠΎΠΊΠ°Ρ ΡΠ°Π΄ΠΈΠ°ΡΠΈΠΎΠ½Π½Π°Ρ ΡΡΠΎΠΉΠΊΠΎΡΡΡ, ΡΡΠΎΠΉΠΊΠΎΡΡΡ ΠΊ Ρ

Hunting down the X17 boson at the CERN SPS
IndexaciΓ³n ScopusRecently, the ATOMKI experiment has reported new evidence for the excess of e+e- events with a mass βΌ 17 MeV in the nuclear transitions of 4He, that they previously observed in measurements with 8Be. These observations could be explained by the existence of a new vector X17 boson. So far, the search for the decay X17 β e+e- with the NA64 experiment at the CERN SPS gave negative results. Here, we present a new technique that could be implemented in NA64 aiming to improve the sensitivity and to cover the remaining X17 parameter space. If a signal-like event is detected, an unambiguous observation is achieved by reconstructing the invariant mass of the X17 decay with the proposed method. To reach this goal an optimization of the X17 production target, as well as an efficient and accurate reconstruction of two close decay tracks, is required. A dedicated analysis of the available experimental data making use of the trackers information is presented. This method provides independent confirmation of the NA64 published results [1], validating the tracking procedure. The detailed Monte Carlo study of the proposed setup and the background estimate show that the goal of the proposed search is feasible.

The paper considers the methodological support and evaluation of operation reliability of rocket and space equipment using the inlet lips of ramjet engine (RJE) as an example. The successful solution to these issues is largely defined by the optimal selection of materials - special high-temperature alloys and structural ceramics.The methods for modeling the loading conditions of the inlet lips in a high-temperature gas flow are developed from the approaches that ensure the similarity of the external effect on the structural element and equivalency of damage to the material under the model and full-scale conditions. The process of modeling of equivalent states of the material of extreme thermally-loaded zones (models) is realized in the form of specialized procedures on a gas-dynamic test bench to investigate the performance of materials and structural elements in high-temperature gas flows with variable thermo-dynamic parameters.The approaches are based on the classical theories of similarity and different dimensions, which were changed and adapted to investigate the thermal cyclic strength of materials and damageability of structural elements under loading in high-speed high-temperature gas flows.The developed procedures and experimental facilities allowed one to carry out a set of investigations on the functional characteristics, as well as obtain the system of properties for three materials at extremely high temperatures. It is demonstrated that the realized methods provide the required information for the development of structural elements operating under conditions of aerodynamic heating.The results of bench tests are presented in compliance with the data obtained in the numerical analysis of the implemented conditions of thermal loading on a gas-dynamic test bench, as well as the calculations of thermal and stress states of the inlet lips made of various materials. Based on the data of experimental and analytical generalization of the boundary heat-exchange conditions, the numerical modeling of the dependence of TSSS of the models on the geometric parameters and physical properties of the material is performed under test bench conditions. It is implied that such comparative tests should be performed using the models of similar shape and the same geometric dimensions since their difference affects the stress state of structural elements significantly.ΠΠ° ΠΏΡΠΈΠΌΠ΅ΡΠ΅ ΠΊΡΠΎΠΌΠΎΠΊ Π²ΠΎΠ·Π΄ΡΡ

Thermal fields diagnostic method of changing aircraft aerodynamic state in flight
A result of the research was the method of aerodynamic condition of the aircraft on the
thermal fields. Based on the mathematical and natural experiments, regularities of formation of temperature gradients in the boundary layer of air that occurs when damage to the contours detected parameters that affect the behavior of the temperature gradient arising from damage, namely the speed and angle of attack of the aircraft, the shape of the profile wings, nature of damage, place of occurrence of damage relative to the outer contours
Pathophysiological and Methodological Aspects of Determining Renal Functional Reserve in Clinical Nephrology
The article pathogenetically substantiates the feasibility of using methods for determining functional renal reserve through salt and water loading of 0.5% sodium chloride in an amount of 0.5 % of the body weight in patients suffering from chronic kidney disease. The informative value of determining the functional renal reserve in clinical nephrology on the example of patients with essential hypertension, diabetes mellitus, and AIDS is shown when assessing the nature and extent of nephron damage
