Abstract	Introduction.In recent years, there has been a tendency to increase the intensity of vehicle traffic on highways around the world, the share of trucks and road trains with an increased number of axles, total load capacity, increased tire pressure is growing. Problems. When designing pavement, the required margin of strength of the layer material to repeat the load should be assigned depending on traffic intensity, traffic flow, its distribution across the width of the roadway, road life and the ability of the material to resist destruction from fatigue. Goal. Develop a method for predicting the durability of cement concrete pavement from the action of vehicles. Results. On the basis of the given theoretical researches it is offered to define a degree of damage of structure of a cement concrete covering from action of vehicles. As is known from the above analysis, the modulus of elasticity of cement concrete pavement on highways is variable from the time of loading, and also confirmed by the results of theoretical and experimental studies of scientists such as Solodkoy S.Y., Levitsky E.F., Chernigova V.A. , Radovsky B.S., Mozgovoy V.V., Sheikina AE etc. Therefore, tensile stresses arise from the action of vehicles in the cement-concrete pavement of highways and fatigue damage occurs over time. Due to the fact that the load of heavy vehicles increases every year, the pressure in the tire tire increases, which is transmitted to the cement-concrete pavement of highways. Conclusions. To predict the durability of cement-concrete pavement of roads from the action of vehicles, an analytical dependence is proposed, which takes into account the total traffic intensity determined by GBN B.2.3-37641918-557 and the maximum allowable amount of design load that can withstand cement-concrete pavement under horizontal tension. when bending. Keywords: highway, pavement, cement concrete, stress, vehicles, fatigue, crack resistance, durability.

В статье рассмотрены основы для выращивания штеклингов в тепличном комплексе, способы предпосевной подготовки почвы, сроки и схема для посева семян компонентов гибридов сахарной свеклы. Качество семян и получение высоких урожаев, с хорошими технологическими свойствами обусловлены условиями выращивания маточной свеклы. В производстве семян гибридов сахарной свеклы на основе цитоплазматической мужской стерильности (ЦМС) в качестве компонентов скрещивания используются раздельноплодные мужско стерильные (МС) и сростноплодные фертильные растения опылители (Оп). Сахарная свекла имеет двухлетний цикл развития. В первый год образуются корнеплоды, предназначенные для выращивания семян, во второй год из вегетативных почек корнеплода вырастает розетка листьев, а из генеративных почек – цветоносные стебли. Широкое применение нашел способ выращивания штеклингов в теплице при ускоренном репродуцировании селекционноценных номеров. В последнее время получило распространение выращивание маточных корнеплодов путем летних загущенных посевов, которые позволяют получить здоровый посадочный материал без дополнительного расширения площадей под маточную свеклу, тем самым увеличить коэффициент размножения. Поэтому разрешение мелких маточных корнеплодов исследования были направлены на изучение способов одногодичного цикла получения семян и выявления среди них наиболее оптимального обеспечивающего высокий выход здорового посадочного материала.
The Impact of COVID on the Development of HRM in Public Service
Authors: Hazafi Zoltán , Kajtár Edit 
Published: March 2022

COVID has had an immense impact on HRM. The aim of this paper is to examine international responses and detect best practices. We analyse a variety of methods, techniques, trends and ideas from all over the world. Insights from Hungary, Austria, Germany, Spain, Italy, Portugal, the Netherlands, the United Kingdom, Ireland, the US and Canada are considered. Work has been transported to virtual space. Home office has grown into being the engine of public service development. It is likely that the future will be characterised by hybrid models. Online operation is intertwined with numerous issues, such as: simplification and increased efficiency of procedures, legal regulation of the transformation and data protection. Numerous questions require our answer as regards the use of virtual space: How will teamwork function? What adjustments are required in learning and development schemes? What is the new role of leaders? How can we assure mental health? How do we promote resilience? Another trend concerns digitalisation of recruitment and selection. Digitalisation is spilling over to the neighbouring areas, such as job branding, mobility management and onboarding. How will the post-COVID era look like? The scale of HRM changes ranges from mere adjustment to paradigm shift. Areas of utmost importance include: consequences of accelerated digital transformation, growing importance of IT skills, new methodology for learning and development, demand for resiliency, sustainable development, efficiency, social dialogue as well as restoration of trust between employer and employee. Public service has to adapt to the modified socio-economic environment. Its structure and functioning require reform. This process incorporates the hope that digitalisation can bring qualitative changes in the functioning of public service. COVID has also brought about a chance to take advantage of the possibilities digital technology can offer. It has enabled us to reinvent the functioning of the state on a higher level.

Abstract
We present the results of variability power spectral density (PSD) analysis using multiwavelength radio to GeV γ-ray light curves covering timescales of decades/years to days/minutes for the blazars 3C 279 and PKS 1510−089. The PSDs are modeled as single power laws, and the best-fit spectral shape is derived using the “power spectral response” method. With more than 10 yr of data obtained with weekly/daily sampling intervals, most of the PSDs cover ∼2–4 decades in temporal frequency; moreover, in the optical band, the PSDs cover ∼6 decades for 3C 279 due to the availability of intranight light curves. Our main results are the following: (1) on timescales ranging from decades to days, the synchrotron and the inverse-Compton spectral components, in general, exhibit red-noise (slope ∼2) and flicker-noise (slope ∼1) type variability, respectively; (2) the slopes of γ-ray variability PSDs obtained using a 3 hr integration bin and 3 weeks total duration exhibit a range between ∼1.4 and ∼2.0 (mean slope = 1.60 ± 0.70), consistent within errors with the slope on longer timescales; (3) comparisons of fractional variability indicate more power on timescales ≤100 days at γ-ray frequencies compared to longer wavelengths, in general (except between the γ-ray and optical wavelengths for PKS 1510−089); (4) the normalization of intranight optical PSDs for 3C 279 appears to be a simple extrapolation from longer timescales, indicating a continuous (single) process driving the variability at optical wavelengths; and (5) the emission at optical/infrared wavelengths may involve a combination of disk and jet processes for PKS 1510−089.
An In-depth Numerical Study of Exact Laws for Compressible Hall Magnetohydrodynamic Turbulence

Published: March 2022

Abstract
Various exact laws governing compressible magnetohydrodynamic (MHD) and compressible Hall-MHD (CHMHD) turbulence have been derived in recent years. Other than their fundamental theoretical interest, these laws are generally used to estimate the energy dissipation rate from spacecraft observations in order to address diverse problems related, e.g., to heating of the solar wind and magnetospheric plasmas. Here we use various 10243 direct numerical simulation data of free-decay isothermal CHMHD turbulence obtained with the GHOST code (Geophysical High-Order Suite for Turbulence) to analyze two of the recently derived exact laws. The simulations reflect different intensities of the initial Mach number and the background magnetic field. The analysis demonstrates the equivalence of the two laws in the inertial range and relates the strength of the Hall effect to the amplitude of the cascade rate at sub-ion scales. When taken in their general form (i.e., not limited to the inertial range), some subtleties regarding the validity of the stationarity assumption or the absence of the forcing in the simulations are discussed. We show that the free-decay nature of the turbulence induces a shift from a large-scale forcing toward the presence of a scale-dependent reservoir of energy fueling the cascade or dissipation. The reduced form of the exact laws (valid in the inertial range) ultimately holds even if the stationarity assumption is not fully verified.
The Effect of Adiabatic Compression on Dark Matter Halos and the Radial Acceleration Relation

Published: March 2022

Abstract
We use a semiempirical model to investigate the radial acceleration relation (RAR) in a cold dark matter (CDM) framework. Specifically, we build 80 model galaxies covering the same parameter space as the observed galaxies in the SPARC database, assigning them to dark matter (DM) halos using abundance-matching and halo mass–concentration relations. We consider several abundance-matching relations, finding some to be a better match to the kinematic data than others. We compute the unavoidable gravitational interactions between baryons and their DM halos, leading to an overall compression of the original Navarro–Frenk–White (NFW) halos. Before halo compression, high-mass galaxies lie approximately on the observed RAR, whereas low-mass galaxies display up-bending “hooks” at small radii due to DM cusps, making them deviate systematically from the observed relation. After halo compression, the initial NFW halos become more concentrated at small radii, making larger contributions to rotation curves. This increases the total accelerations, moving all model galaxies away from the observed relation. These systematic deviations suggest that the CDM model with abundance matching alone cannot explain the observed RAR. Further effects (e.g., feedback) would need to counteract the compression with precisely the right amount of halo expansion, even in high-mass galaxies with deep potential wells where such effects are generally predicted to be negligible.
Impact of 3D Structure on Magnetic Reconnection

Published: March 2022

Abstract
Results from 2.5D and 3D studies of the onset and development of the tearing instability are presented, using high-fidelity resistive MHD simulations. A limited parameter study of the strength of the reconnecting field (or shear angle) was performed. An initially simple 1D equilibrium was used, consisting of a modified force-free current sheet, with periodic boundary conditions in all directions. In all cases, the linear and nonlinear evolution led to a primary current sheet between two large flux ropes. The global reconnection rate during this later stage was analyzed in all simulations. It was found that in 2.5D the primary current sheet fragmented owing to plasmoids, and as expected, the global reconnection rate, calculated using multiple methods, increases with the strength of the reconnecting field owing to a stronger Alfvén speed. In 3D, the presence of interacting oblique modes of the tearing instability complicates the simple 2.5D picture, entangling the magnetic field of the inflow and introducing a negative effect on the reconnection rate. The two competing effects of stronger Alfvén speed and entangling, which both increase with the strength of the reconnecting field, resulted in a decrease in the reconnection rate with increasing reconnecting field. For all simulations, the 3D rates were less than in 2.5D but suggest that as one goes to weak reconnecting field (or strong guide field) the system becomes more 2.5D-like and the 2.5D and 3D rates converge. These results have relevance to situations like nanoflare heating and flare current sheets in the corona.

The demand for the use of radioactive isotopes in medicine is increasing with each coming year necessitating the increased output of radionuclide products. One of the most widely spread radionuclides used in medicine is technetium-99m (99mТс) (Feasibility of producing molybdenum-99 2015, NEA 2012, The Supply of Medical Radioisotopes 2015). The very short 99mТс life (6-hour half-life) requires its production directly on the site of medical treatment. This is achieved using molybdenum-technetium generators (Kodina and Krasikova 2014, Technical Reports No. NF-T-5.4. 2013, Technetium-99 Generator 2021) loaded with molybdenum-99 (99Мо), which uninterruptedly decays (half-life of 66 hours) yielding 99mTc.
Close attention must be paid in the course of production of molybdenum-technetium generators to radiation safety during transportation of 99Мо on the territory of the manufacturing facility. The main measure for ensuring radiation safety during transportation of 99Мо is the application of special packaging kits. The Karpov Institute of Physical Chemistry JSC uses a wide range of packaging kits of types A and B for transportation of radioactive materials on the territory of the manufacturer with design features providing the required level of radiation safety.
In particular, the KL-15 shipping cask loaded/unloaded from the top is used for onsite transportation of 99Мо for charging molybdenum-technetium generators. The maximum permissible activity of 99Мо is not specified in the passport of the KL-15 cask. Planned construction of a radionuclide production shop in accordance with GMP requirements will require the increase of output of target radionuclides by several times. The above considerations necessitated the evaluation of the maximum permissible activity of 99Мо planned to be transported in KL-15 casks. No other type of standard casks can be used because of their outside dimensions prohibiting the unloading of 99Мо inside the “hot” chamber. Calculation and experimental evaluation of permissible 99Мо activity during transportation inside the KL-15 cask was performed.
The paper presents the calculated evaluation of the maximum permissible activity of 99Мо in a KL-15 cask to ensure the radiation exposure of personnel of group A working with the cask not exceeding the established level at the enterprise (80 μSv per shift) and not requiring the use of additional measures and means of protection.
The results of the work allow us drawing the conclusion that the KL-15 cask ensures the required level of radiation safety with up to 241 Ki of 99Мо loaded in the cask.

Cet article cherche à mesurer l’impact de la crise sanitaire de la Covid-19 sur l’emploi local en France métropolitaine. En partant d’une vaste littérature sur la résilience économique et des premières données locales disponibles sur le nombre de suppressions d’emplois, nous mettons en évidence, d’une part, les différences de résilience des zones d’emploi face à la crise et, d’autre part, les facteurs explicatifs clefs à l’origine de ces disparités. Les premiers résultats économétriques montrent une influence significative de la densité, du niveau de l’emploi dans l’industrie, de la structure productive ainsi que de la dynamique entrepreneuriale du territoire. En revanche, aucune relation n’est trouvée entre les zones d’emploi présentant des niveaux importants de surmortalité et celles qui ont le plus enregistré de pertes d’emplois.

Abstract
This paper aims to share a new concept of assets condition assessment knows as Integrated Metal Magnetic Memory (i-MMM) which integrates capability of various Non-Destructive Testing (NDT) technology in determining the current state of deformed pipeline due to external loadings.
MMM technology is one of NDT technique which can be used for early failure detection especially for Stress Concentration Zones (SCZ), microcrack and fatigue damage for ferromagnetic components. MMM is a passive technology tools that relies on the measurement of Self-magnetic Leakage Field (SMLF) of the ferromagnetic materials. Most of the traditional NDT method able to inspect the macro defect but incapable to identify micro defect due to the stress concentration zone. Based on this, MMM can be integrated and complimentary in its capability to other well-known NDT testing such as Ultrasonic Testing (UT) and Hardness Test.
A case study presented whereby iMMM can be utilized to determined location which are prone to deformation due to stress and detailed assessment from changes of hardness up to development of macro size defect. Based on the findings in the case study, 2 microcrack were found at 2 inspected location of the pipeline.
Finally, based on the results and findings from the integrated approach of i-MMM, it can contribute and provide more impact on the simulation analysis by providing focused anomaly area or location and reduced the processing time.
