Authors: Gallenne A. , Mérand A. , Kervella P. , Graczyk D. , Pietrzyński G. , Gieren W. , Pilecki B.
Published: February 2023

Aims. We aim to measure very precise and accurate model-independent masses and distances of detached binary stars. Precise masses at the < 1% level are necessary to test and calibrate stellar interior and evolution models, while precise and independent orbital parallaxes are essential to check for the next Gaia data releases.

Methods. We combined RV measurements with interferometric observations to determine orbital and physical parameters of ten double-lined spectroscopic systems. We report new relative astrometry from VLTI/GRAVITY and, for some systems, new VLT/UVES spectra to determine the radial velocities of each component.

Results. We measured the distance of ten binary systems and the mass of their components with a precision as high as 0.03% (average level 0.2%). They are combined with other stellar parameters (effective temperatures, radii, flux ratios, etc.) to fit stellar isochrones and determine their evolution stage and age. We also compared our orbital parallaxes with Gaia and showed that half of the stars are beyond 1σ with our orbital parallaxes; although, their RUWE is below the frequently used cutoff of 1.4 for reliable Gaia astrometry. By fitting the telluric features in the GRAVITY spectra, we also estimated the accuracy of the wavelength calibration to be ∼0.02% in high and medium spectral resolution modes.

Conclusions. We demonstrate that combining spectroscopic and interferometric observations of binary stars provides extremely precise and accurate dynamical masses and orbital parallaxes. As they are detached binaries, they can be used as benchmark stars to calibrate stellar evolution models and test the Gaia parallaxes.
Astrophysical properties of 15062GaiaDR3 gravity-mode pulsators
Authors: Aerts C. , Molenberghs G. , De Ridder J.
Published: February 2023

Context.Gravito-inertial asteroseismology came into existence thanks to high-precision CoRoT andKeplerspace photometric light curves. So far, it has given rise to the internal rotation frequency of a few hundred intermediate-mass stars, yet only several tens of these have been weighed, sized, and age-dated with high precision using asteroseismic modelling.

Aims.We aim to increase the sample of optimal targets for future gravito-inertial asteroseismology by assessing the properties of 15062 newly foundGaiaDR3 gravity-mode pulsators. We also wish to investigate whether or not there is a connection between their fundamental parameters, the dominant mode, and their spectral line broadening as measured byGaia.

Methods.After reclassifying about 22% of the F-type gravity-mode pulsators as B-type according to their effective temperature, we constructed histograms of the fundamental parameters and mode properties of the 15062 newGaiaDR3 pulsators. We compared these histograms with those of 63Keplerbona fide class members. We fit errors-in-variables regression models to couple the effective temperature, luminosity, gravity, and oscillation properties to the twoGaiaDR3 parameters capturing spectral line broadening for a fraction of the pulsators.

Results.We find that the selected 15062 gravity-mode pulsators have properties that are fully in line with those of their well-knownKepleranalogues, revealing thatGaiahas a role to play in asteroseismology. The dominantɡ-mode frequency is a significant predictor of the spectral line broadening for the class members for which this quantity has been measured. We show that theGaiavbroadparameter captures the joint effect of time-independent intrinsic and rotational line broadening and time-dependent tangential pulsational broadening.

Conclusions.While theGaiamission was not designed to detect non-radial oscillation modes, its multitude of data and homogeneous data treatment allow us to identify a vast number of new gravity-mode pulsators that have fundamental parameters and dominant mode properties in agreement with those of suchKeplerbona fide pulsators. This large new sample ofGaiaDR3 pulsators can be followed up with dedicated high-precision photometric or high-resolution spectroscopic instruments to embark on asteroseismic modelling.
Heating and ionization by non-thermal electrons in the upper atmospheres of water-rich exoplanets
Authors: García Muñoz A.
Published: February 2023

Context. The long-term evolution of an atmosphere and the remote detectability of its chemical constituents are susceptible to how the atmospheric gas responds to stellar irradiation. The response remains poorly characterized for water and its dissociation products, however, this knowledge is relevant to our understanding of hypothetical water-rich exoplanets.

Aims. Our work investigates the effect of photoelectrons, namely, the non-thermal electrons produced by photoionizing stellar radiation on the heating and ionization of extended atmospheres dominated by the dissociation products of water.

Methods. We used a Monte Carlo model and up-to-date collision cross sections to simulate the slowing down of photoelectrons in O-H mixtures for a range of fractional ionizations and photoelectron energies.

Results. We find that that the fraction of energy of a photoelectron that goes into heating is similar in a pure H gas and in O–H mixtures, except for very low fractional ionizations, whereby the O atom remains an efficient sink of energy. The O–H mixtures will go on to produce more electrons because the O atom is particularly susceptible to ionization. We quantified all that information and present it in a way that can be easily incorporated into photochemical-hydrodynamical models.

Conclusions. Neglecting the role of photoelectrons in models of water-rich atmospheres will result in overestimations of the atmospheric heating and, foreseeably, the mass-loss rates as well. It will also underestimate the rate at which the atmospheric gas becomes ionized, which may have implications for the detection of extended atmospheres with Lyman-α transmission spectroscopy. Our simulations for the small exoplanets π Men c and TRAPPIST-1 b reveal that they respond very differently to irradiation from their host stars, with water remaining in molecular form at lower pressures in the latter case.

Context. We are operating an elastic light detecting and ranging system (LIDAR) for the monitoring of atmospheric conditions during regular observations of the MAGIC telescopes.

Aims. We present and evaluate methods for converting aerosol extinction profiles, obtained with the LIDAR, into corrections of the reconstructed gamma-ray event energy and instrument response functions of Imaging Atmospheric Cherenkov Telescopes.

Methods. We assess the performance of these correction schemes with almost seven years of Crab Nebula data obtained with the MAGIC telescopes under various zenith angles and different aerosol extinction scenarios of Cherenkov light.

Results. The methods enable the reconstruction of data taken under nonoptimal atmospheric conditions with aerosol transmissions down to ~0.65 with systematic uncertainties comparable to those for data taken under optimal conditions. For the first time, the correction of data affected by clouds has been included in the assessment. The data can also be corrected when the transmission is lower than 0.65, but the results are less accurate and suffer from larger systematics.

Published: February 2023

The current state of development of deposits with high-viscosity oils is characterized by a low value of the achieved oil recovery with a high water cut in the produced wells. However, ways to improve the implemented development systems in order to increase the recovery factor in conditions of high water cut in well production, especially in the late stage of operation requires further research. Therefore, this research intended to investigate features of filtration of non-Newtonian oils in a porous medium. Oil fields with a complex geological structure have been discovered in many oil and gas regions of the world. These fields are characterized by a small oil-saturated thickness of the reservoirs, low reservoir properties, high viscosity of reservoir oil and heterogeneity of productive horizons. To study the filtration process, a specially designed installation was used. Clearly, the main elements are a column (core holder) with a water jacket, an oil tank, a thermostat and a high-pressure air tank (compressor). A research experiment was undertaken in two oil fields, which are X and Y. The results of physicochemical properties of oil field X showed that the density was 0.878g/cm3, followed by sulfur content (1.51%), pitches (21.89), asphaltenes was 4.19, and paraffin was 5.18.

Published: February 2023

In a comparative aspect and dynamics in the conditions of urbanized territories, the structure of invasive pathology and the effectiveness of anti-invasive measures were studied. It was established that the epizootic situation is controlled by parasitological, microscopic and hematological studies for 12 invasions. It was determined that from the period from 2020 to 2022, there is a negative trend in the defeat of farm animals and unproductive domestic animals with invasive diseases (from 25% in 2020 to 0.57% in 2022). At the same time, nematodes play a leading role in the invasive pathology of animals - from 60.5% of those affected in small cattle to 0.6% in dogs. In our opinion, the negative dynamics is associated with the optimization of the system of anti-epizootic measures in a metropolis, aimed at the source of the pathogen, the mechanism of its transmission and susceptible animals. It was stipulated that in order to control and determine the effectiveness of the implementation of an optimized scientifically based system of antiparasitic measures, continuous study and assessment of the epizootic situation among cattle are required; laboratory screening of animals and habitat.

Published: February 2023

The relevance of gypsum materials in the context of "Eco-construction" is beyond doubt, since gypsum is exactly the building material that fully meets the requirements of ecology and environ-mental protection. Improving the efficiency of gypsum building materials by creating new modi-fied materials with improved technical and operational characteristics currently remains an im-portant and urgent task. In conditions of energy and resource saving due to the lack of the need to build new production lines and sections, this problem was solved by creating modified gypsum materials with improved functional performance properties through the use of modern highly effective modifying micro- and nano-additives. The paper discusses the effect of nanocellulose and styrene latex microadditives on the morphology and properties of gas gypsum – compressive and flexural strength, and sound absorption coefficients. We used a standard gypsum binder of the Peshelan gypsum plant grade G-6. Crystalline citric acid was used as a gas - forming agent. An aqueous emulsion butadiene-styrene latex and an aqueous suspension of nanocellulose were used as strengthening and modifying structuring microadditives.

Authors: Galkin Aleksandr , Pankov Vladimir , Fedorov Yan
Published: February 2023

A correct consideration of the thermal factors during the design phase of civil engineering structures in the permafrost area determines their reliable and safe exploitation. Among the important indicators in selection of design solutions is the thermal conductivity coefficient of the construction materials used. The thermal conductivity coefficient is usually chosen from reference tables, but when using mixtures, the thermal conductivity coefficient is determined through a calculation. The aim of the present research was to compare the calculated values of thermal conductivity coefficient of binary mixtures (a mixture of a binding material and a filler) obtained using Lichtenecker and Schwerdtfeger formulas. The comparison was conducted in the range of properties of materials used for thermal accumulation and thermal insulation mixtures. It was determined that for thermal accumilation binary mixtures the calculation results are quite similar within a wide range of initial values. For thermal insulation binary mixtures, the calculation results are significantly different. The divergencies are by hundreds of percents. At the current stage of research it is impossible to make a conclusion about suitability of either calculation method to determine the thermal conductivity of a thermal insulation binary mixture.

Authors: Lukashov Sergey , Gamazin Victor , Ivanchenkova Oksana
Published: February 2023

In this paper, an ecological and chemical safety assessment of using RDF (Refuse-derived fuel) is considered. It is shown that production and consumption wastes, including combustible unclaimed fractions of secondary material resources from household solid waste, which have undergone preliminary sorting and preparation, in terms of grinding and cleaning from non-combustible inert materials, are used as raw materials for its manufacture. It has been established that it is expedient to use this type of fuel during thermal decomposition (pyrolysis) with a working temperature of about 1200-1500 °C, since at this temperature all substances pass into the composition of flue gases. Installation "Mark 1" is proposed, which can be used in boiler station for burning RDF. The technological scheme and the principle of operation of the proposed installation are described. An assessment of the impact of the operation of this installation on the environment was carried out. It is shown that the concentrations of pollutants from the heating system, according to the protocol for measuring quantitative chemical analysis (QCA) of emissions into the atmosphere at control points at a distance of 25 meters from the mouth of the boiler station pipe, using the example of pilot tests of RDF, do not exceed the MPC. Thus, the ecological and chemical safety of RDF is confirmed and its use in combustion plants equipped with swirling-type furnaces is justified.

Published: February 2023

The article presents research materials on testing the hypothesis about the priority of principles of relevance and coordination when forming the composition of indicators included in social reporting of companies and statistical books by region. To test the hypothesis general scientific methods of analysis and synthesis, statistical methods for processing data on the use of indicators characterizing the human resources of the region and the company, and the secondary analysis of the results of studies published by Russian scientists on social reporting were used. The lack of proposals on overcoming problems of inconsistency of indicators characterizing human resources of systems at different levels, the region and the company, predetermined the need to study this topic. The authors systematized indicators of the level of human resources of companies and the region, which made it possible to analyze their comparability. The results of the analysis determined both priority principles for formation of the information base on human resources and proposals for its formation. Implementation of the proposals will contribute to the creation of a more informative and coordinated information system on the state of human resources, which is of practical importance in organizing personnel security in the region and in companies.

Support solutions and promote the sustainable development of customs, investigate and formulate measures for the management of an innovative control model. It is difficult to underestimate the positive effect of the policy pursued by the FCS, which is also implemented on the basis of the recommendations of the World Customs Organization and the provisions of the Kyoto Convention of 1999. The time for customs formalities has been significantly reduced, electronic declaration centers have been established, allowing for the registration of goods located on the territory of different customs posts. At the same time, the number of contacts of declarants with officials has been minimized due to the categorization of foreign trade participants and the improvement of the risk management system, which allows achieving maximum efficiency with minimal invested costs of the customs authority for conducting this control. However, such an active process of introducing technical means, without which it is impossible to imagine the functioning of customs authorities today, cannot remain without flaws, manifested mainly in customs document management.

Improving seismic resistance using absorbing nodes
Authors: Skachkov S. V. , Kotenko M. P.
Published: February 2023

A flexible gusset is a device that improves the seismic resistance and energy dissipation capacity of a structure. To achieve these solo vibration characteristics, the flexible gusset is designed to remain elastic, resulting in reduced vibration to the structure. The designed energy-absorbing gusset is attached to the column with bolts, thereby connecting the ties to the column and putting them into operation while dissipating vibration. The proposed design was theoretically studied using modeling and calculation in the STARK-ES software package, which allows you to carry out calculations of buildings and structures for stability, as well as calculate natural vibrations in a relatively deformed state, taking into account the one-sided operation of the elements, create a calculation of constraints for forced vibrations with an arbitrary, power, kinematic and dynamic load. The results of the calculation of the bearing capacity assessment showed that the reliability of the system in places of critical stresses was increased. These results allow us to assume that the use of energy-absorbing gussets of frame ties increases the seismic resistance of the building and reduces the load on the foundations of the building than with standard fastening of columns and ties.

In the paper an appreciable hierarchy of mathematical models is proposed. It describes the actual dynamics of COVID-19 thickness during 02/12/2020 – 09/22/2021. The incidence sub-model reflects reliably regular (aperiodic and periodic), as well as random components. It is established that the dynamics of the epidemy is essentially seasonal thrice a year. Model elaborated enables to clarify and explain weak weekly fluctuations in the death rate dynamics. It turned out that the maximum risk of death is at 15 and 22 days of disease duration. It means that this virus will presumably be a "satellite" of the human population with corresponded mortality at 1.75%. Calculations performed enable to estimate the level of stochastics in disease and death dynamics. It is near to the amplitude of periodic variation. Computer experiments with developed model predict the global dynamics of the incidence of COVID-19. New epidemic data can show the prospect of improving our model to regard the competitiveness between new sporadically emerging virus strains.

This article presents the measures and necessary recommendations to reduce the load on the stations, making efficient use of the processing capacity of the stations in the conditions of imbalanced wagon-flows. Also, analyzed the factors that influence the loading of railway stations according to their place of geographical location. Proposals have been made to reduce the level of load arising at the technical stations of the railway using the “Ishikawa” diagram.

The effect of sewage sludge as a fertilizer-ameliorant in the safflower cultivation was studied. Sewage sludge from Volzhskij wastewater treatment plants prepurified by enzyme-cavitation method was used as a fertilizer-ameliorant in the safflower cultivation. It was found that prepurified sewage sludge is environmentally friendly and has a high fertilizing value. The amino acid composition of safflower seeds was studied. The obtained data indicate that sewage sludge introduction made it possible to significantly increase the safflower nutritional value and the soil microbiological activity. It was found that the greatest increase in the safflower crop yields was observed in the case of sewage sludge introduction at a dose of 10 t/ha with chisel tillage. It can be stated that the technology of safflower cultivation proposed by us, including the application of sewage sludge as a fertilizer-ameliorant in combination with the chisel tillage, significantly affects its productivity. The increase in safflower crop yields over the years of the studies was 8.4-15.3%. In general, it can be concluded that sewage sludge has a complex effect on the soil: improves its water-physical, agrochemical and physico-chemical properties, increases the activity of soil biota and the content of organic matter – one of the main indicators of soil fertility.

Development of virgin and fallow lands in Kazakhstan has highlighted a number of problems in the economy of the republic. Introduction of huge territories into land turnover in extreme conditions required search and creation of irrigation system in the North-Kazakhstan region. Authors note that in the North-Kazakhstan region, having difficult natural-climatic conditions caused by sharply continental climate, there was a deficit of fresh artesian water. Therefore, one of the main directions of agrarian policy in the North-Kazakhstan region was to increase the efficiency of irrigated land use, liman irrigation, water supply to settlements, watering of the territory and qualitative improvement of irrigation and reclamation works. The authors conclude that despite the measures taken, the established irrigation systems did not meet the needs of agriculture and the population of the region.
Krankenhauszukunftsgesetz – Voraussetzungen und Chancen gelingender Digitalisierung im deutschen Krankenhauswesen
Authors: Meer Florian , Grau Armin
Published: February 2023

Digitalisierung ist allgegenwärtig im Alltag. Sie begegnet uns Menschen im Privatleben, in der Wirtschaft, im sozialen Bereich und ist ständiger Begleiter der politischen Debatten jeglicher
Ressorts – dies betrifft auch nahezu sämtliche gesundheitspolitischen Themen. Im Kontext der Krankenhauspolitik wird sie ebenso oftmals als wichtiges Ziel der gegenwärtigen Entwicklung des
Krankenhauswesens ausgerufen und das zurecht: Das deutsche Krankenhauswesen ist insbesondere im europäischen Vergleich noch relativ wenig digitalisiert und bietet dementsprechend ein hohes
Potenzial für durch die Politik initiierte Digitalisierungsprozesse.

Das 2020 implementierte Krankenhauszukunftsgesetz hatte durch finanzielle Bereitstellung auf Bundes- und Länderebene hatte eben jene Beförderung des digitalen Transformationsprozesses zum
Ziel: Gefördert werden seitdem u. a. Investitionen in Patient*innenportale, IT-Sicherheit, moderne Notfallkapazitäten und E-Health. Bis hierhin kann festgehalten werden, dass das
Krankenhauszukunftsgesetz einen wichtigen Teil zur Digitalisierung im deutschen Krankenhauswesen beigetragen hat. Gleichwohl gilt es, die Effekte des Krankenhauszukunftsgesetzes weiter zu
evaluieren und gleichzeitig andere wichtige Hebel in Form von politischen Reformen zu betätigen, um langfristig eine bedarfsgerechte und an den Patient*innen orientierte
Krankenhausversorgung gewährleisten zu können.

Dies inkludiert in besonderem Maße eine reformierte a) Krankenhausfinanzierung, die das bestehende DRG-System um ein nach Versorgungsstufen differenziertes System erlösunabhängiger
Vorhaltepauschalen ergänzt, b) eine Krankenhausplanung, die sich an inhaltlichen Leistungsbereichen orientiert und regionale Krankheitslasten sowie Anfahrtszeiten berücksichtigt und
schließlich c) eine intensivierte sektorenübergreifende Versorgung, um gerade Menschen in urbanen, sozial benachteiligten Regionen und im ländlichen Raum adäquat versorgen zu können.

Wird die digitale Transformation im deutschen Krankenhauswesen simultan mit den genannten essenziellen Reformen des Krankenhaus- und Gesundheitswesens gedacht, kann langfristig ein
Krankenhauswesen in Deutschland persistiert werden, das auch weiteren wichtigen Herausforderungen der Zeit begegnen kann und dabei eine bedarfsgerechte Versorgung der Menschen ermöglicht und
die Interessen der Patient*innen wieder mehr in den Fokus rückt.
